Blockage-preventing feeding device for blowing feeding machine and feeding method

Abstract

The invention discloses a blockage-preventing feeding device for a blowing feeding machine and a feeding method. The blockage-preventing feeding device for the blowing feeding machine comprises a feeding cylinder, a feeding hopper and connection rods. A material pushing rod is arranged in the feeding cylinder. The feeding hopper is installed above the feeding cylinder. A screening net is arrangedin the feeding hopper. The bottom of the screening net is connected with elastic springs. The bottoms of the elastic springs are provided with fixing plates. The fixing plates are installed on the inner wall of the feeding hopper. The bottom of the connection rod is connected with the screening net. The connection rods are arranged in grooves. The grooves are formed in the feeding hopper. The inner wall of the feeding hopper is provided with cushion blocks located below the fixing plates. According to the blockage-preventing feeding device for the blowing feeding machine, the screening net isarranged in the feeding hopper and is inclined, in this way, when particulate matter falls, particles large in diameter can be blocked by the screening net and slide to the low end of the screening net, and falling of other materials cannot be influenced.

Description

technical field [0001] The invention relates to the technical field of blowing and injection machines, in particular to an anti-clogging feeding device and a feeding method for blowing and injection machines. Background technique [0002] Blowing and injection machine is a kind of mechanical equipment commonly used in processing workpieces. Usually, granular raw materials are injected into the hopper, and then the raw materials enter the barrel from the hopper, and are heated and pressurized in the barrel, and then the raw materials enter into the barrel through the action of the push rod. In the cavity, the raw material molding operation is carried out. [0003] However, the existing blowing and injection machine feeding device cannot sieve and filter the granular raw materials during the feeding process, resulting in the phenomenon that the larger particle size is easy to block the discharge end of the hopper, and the raw materials are easy to be separated from the hopper....

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of anti-clogging blowing injection machine feeding device and feeding method, to solve the problem that the current blowing injection machine feeding device on the market proposed by the above-mentioned background technology cannot correct the particle shape during the feeding process. Raw materials are sieved and filtered, resulting in the phenomenon that the larger particle size is easy to block the discharge end of the hopper, and the raw materials are easy to stick to the inner wall of the hopper, which is not easy to clean, which affects the cleanliness of the hopper and reduces the intake. The problem of the practicality of the feeding device
