Problems solved by technology
[0003] However, none of the existing hoppers has a processing device, which leads to different particle sizes of raw materials entering the device, which leads to different degrees of dissolution of raw materials with different particle sizes at the same temperature. The raw materials are not completely dissolved or the dissolution time is too long. It may lead to too many impurities and impure color of the product, which does not meet the requirements of product quality; and the existing polyvinylidene fluoride rod hot pressing extrusion device has only one mold, which can only produce one product at a time, and the production efficiency low

The invention discloses a polyvinylidene fluoride bar hot-pressing extruding device which comprises an oil cylinder box. An oil pressing barrel is arranged inside the oil cylinder box, and is connected with a screw splined groove. The screw splined groove is connected with a screw through a screw transmission gear. A hopper is connected with one end, close to the surface of the screw transmission gear, of the top end of the screw. A vibrating mesh is arranged inside the hopper, and is controlled by a motor I at the outer part of the hopper. A heater is arranged on the surface of the screw. The screw is connected with a transmission pipe. The transmission pipe is connected with a charging barrel. The charging barrel is connected with a plurality of dies by means of a spray nozzle in the middle of a fixed die plate. Fixed nuts are arranged on the surface of the fixed die plate. The vibrating mesh and the motor I used in a manner of cooperating with the vibrating mesh are arranged inside the hopper, so that the raw material particles entering the hot-pressing extruding device are little in size difference, and the purity of the product is higher; a fixing device and the fixed nuts are arranged, so that the whole device is dismantled more conveniently; and through the arrangement of the dies, the working efficiency of the device is higher.
Description
technical field [0001] The invention relates to the industrial field, in particular to a polyvinylidene fluoride rod hot-press extrusion device. Background technique [0002] Polyvinylidene fluoride plastic is a kind of plastic with high strength and high toughness under low temperature conditions. The maximum allowable working temperature in the air is between minus 60 degrees and plus 150 degrees (it can work continuously at a temperature of 150 degrees). Excellent chemical corrosion resistance and hydrolysis resistance, outstanding UV resistance and weather resistance, high mechanical strength, good rigidity, good creep resistance, good sliding and wear resistance, inherent low flammability, point insulation Good performance. Can be used on pipes, seals, pump components, rotating discs, valves, slides, etc. It is suitable for component manufacturing in petrochemical, chemical, metallurgy, food, paper, textile, pharmaceutical and atomic energy industries. The pharmaceut...
