  • Consumables for cryogenic trimming machine – supply of liquid nitrogen Consumables for cryogenic trimming machine – supply of liquid nitrogen
    Apr 10, 2024
    Consumables for cryogenic trimming machine – supply of liquid nitrogen   The frozen cryogenic deflashing machine, as an essential auxiliary manufacturing machinery in the production process of rubber enterprises, has been indispensable. However, since its entry into the mainland market around the year 2000, local rubber enterprises have little knowledge of the working principles and processes of the frozen trimming machine. Therefore, this article will provide a detailed introduction to the storage and supply methods of the cryogen, liquid nitrogen, for cryogenic deflashing machine. In the past, liquid nitrogen was typically stored in separate liquid nitrogen tanks. Therefore, when purchasing a cryogenic trimming machine, it was necessary to buy a matching liquid nitrogen tank to ensure the proper operation of the machine. The installation of the liquid nitrogen tank required approval from the relevant authorities, which was a cumbersome process, and the tanks themselves were expensive. This has led many factories that urgently need to use cryogenic deflashing machines to improve work efficiency to hesitate, as it also involves a certain upfront cost investment. Nanjing PEGE has introduced a liquid nitrogen manifold supply station to substitute for liquid nitrogen tanks. T his system centralizes the gas supply of individual gas points, enabling multiple low-temperature Dewar flasks to be combined for centralized gas supply. It solves the cumbersome process of handling liquid nitrogen tanks, allowing customers to operate the frozen edge trimming machine immediately after purchase. The main body of the system simultaneously connects three bottles of liquid nitrogen Dewar flasks, and it also includes a port that can be expanded to accommodate four bottles. The system pressure is adjustable and equipped with a safety valve. It’s easy to assemble and can be mounted on the wall using a triangular bracket or placed on the ground using the bracket.

    The definition, principal, and composition of a typical Cryogenic Deflashing Machine A cryogenic deflashing machine, also known as a cryogenic deburring system, is a type of equipment used to remove excess material or flash from molded or machined parts. Cryogenic deflashing is a process that involves the use of extremely low temperatures to freeze the parts and then removing the flash using various methods. The cryogenic rubber deflashing machine typically consists of a large chamber or tub where the parts are placed. Liquid nitrogen  is used to rapidly cool the parts, making them brittle. Once the parts are sufficiently cooled, they are subjected to tumbling or blasting action, which causes the brittle flash to break off from the parts. The rubber or plastic flash is then separated from the parts using air, vibration, or other means. Cryogenic deflashing is commonly used in industries such as automotive, aerospace, electronics, and medical devices, where precision and cleanliness are critical. It is an effective and efficient method for removing flash from complex-shaped parts without damaging the component itself. Moreover, cryogenic deflashing is considered to be environmentally friendly compared to traditional methods that involve the use of harsh chemicals or mechanical trimming. Nanjing Pege Techno is a leading supplier of various type of cryogenic deflashing machines.

When the feeder is running, the motor drives the feeding screw, vibrator or pump to move. At the same time, the material in the measuring hopper flows out. By reducing the weight in the unit time, obtain the actual feeding amount, compare it with the set feeding amount to get the error value, and then adjust the speed of the feeding motor through the PID closed-loop control algorithm to achieve the precise feeding requirements. This process ensures an accurate feeding or dosing during the production process. The general purpose of Loss in Weight feed system is to accurately weigh and control the output of variable products either, continuously or as a batch. Benifits Typical loss–in-weight feeders are used to negate the use of weigh hoppers and to eliminate the impact of material. This system is particularly useful when the product to be weighed is sticky and does not have good flow properties. A. Improve measurement accuracyB. Reduce premixing workloadC. Improve product stabilityD. Reduce dust pollution and be more environmentally friendly. E. Improve work and production efficiency.

    Loss-in-Weight Overview Principle In loss-in-weight feeding, the entire feeder, hopper and material are continuously weighed. As the feeder discharges material, the rate of decline in system weight is computed, and feeder speed is adjusted to maintain the desired (set) rate. Advantages, Limitations and Considerations Accuracy – In practice, with today’s advanced weighing and control technologies, reliably high performance accuracy is routinely realized, notwithstanding the significant demands placed on weighing and control operations in loss-in-weight feeding.   Range – Loss-in-weight feeding systems are available for the complete range of rates encountered in plastics compounding and extrusion operations.   Material Handling - Any feeding device suitable to the process material can be employed (e.g., screw, auger, vibrating tray, etc.). Even liquids whose specific gravity varies can be gravimetrically controlled by substituting the hopper/feeder with a holding tank and pump or control valve. (Related info)   Material Containment - Loss-in-weight feeders readily lend themselves to complete material containment where dusting or safety/toxicity concerns apply.   Tare – Under the loss-in-weight principle, moment-to-moment differences in weight matter, not absolute weight. Thus, for the purpose of feed rate control, tare becomes irrelevant.   Weighing – Considering the fact that loss-in-weight feeding involves the accurate detection of small, moment-to-moment changes in system weight while simultaneously weighing a relatively massive feeding system, the demands on the weighing system are substantial. Such measurement requires the highest possible levels of resolution, linearity and stability along with sophisticated filtering and signal processing to extract meaningful weight data from spurious disturbances such as jostling or ambient vibration in the process environment.    Isolation – Loss-in-weight feeders must be effectively isolated from their environment for accurate weighing. Flexible supply and discharge connections typically suffice for process connections, and appropriate measures may be needed at installation to assure that in-plant vibration is not transmitted to the feeder through its mounts.   Refill - Periodic hopper replenishment is required. During this intentionally brief phase, whether accomplished manually or by an automated system, weight measurement is unavailable due to the inflow of material, temporarily preventing true gravimetric control. For materials whose density does not increase appreciably with increasing headload (such as pellets, for example), feeder speed can be held constant throughout refill. Or, for variable-density powders, granules and the like, feeder speed may be automatically reduced to gradually slow feeder speed during refill, accurately compensating for the effect of increasing headload-related material compaction. (Related info)   Size - Unlike the other two operating principles presented below, the physical size and installation footprint of loss-in-weight feeding systems roughly corresponds to its feed rate range. This makes for a relatively small and compact feeder when handling additives, a major benefit where space is at a premium such as when clustering units over an extruder inlet. However, physical size may become a concern for higher rate installations. High-rate feeders tend to be large, require a correspondingly large installation footprint, and may also require a significant support structure. Because of its high accuracy, innate material handling flexibility and ease of material containment, combined with enabling advances in weighing and control, loss-in-weight feeding has matured to become the dominant approach to gravimetric flow rate control since its introduction nearly 50 years ago.
