Reloading method of molding plastic extruding machine hopper

Abstract

The invention discloses a reloading method of a molding plastic extruding machine hopper. The molding plastic extruding machine hopper comprises a hopper body, and further comprises a chute fixedly mounted on a plastic extruding machine, wherein the internal width of the chute is greater than the opening width thereof; a feed port communicated with the plastic extruding machine is formed in the bottom of the chute; an upper slide block and a lower slide block are mounted below the hopper body, are respectively positioned inside and outside the chute, and are connected through a pipe; an internal cavity of the hopper body is communicated with the feed port by a pipe; and the chute outwards extends, and is provided with an unloading hole in the bottom. The hopper body has no need to be taken down, so that higher labor intensity is prevented; and as the hopper body has no need to be overturned, compared with a structure form of a traditional hopper fixed on the plastic extruding machine, the problems of troublesome material variety replacement, material residue and high labor intensity of workers are solved, and the purpose of quick replacement is realized.

Description

technical field [0001] The invention relates to a hopper of an extruder in the sensor manufacturing industry, in particular to a material changing method for forming a hopper of an extruder. Background technique [0002] Automobile wheel speed sensor is mainly composed of sensor head, wiring harness and accessories. The function of the induction head is to cooperate with the target gear installed on the chassis of the car to measure the speed of the car wheel, which is composed of coils, magnetic poles and other parts. On this basis, in order to ensure the normal operation of the sensor, the sensor must be properly installed on the chassis of the vehicle, and there are many installation methods. There is a wheel speed sensor commonly used now, which relies on the outer steel casing of the induction head to cooperate with a part, namely, an elastic bushing, and install it into the corresponding mounting hole of the chassis. When designing the sensor, it is necessary to comb...

Problems solved by technology

The chute is in the shape of a cuboid as a whole, with an opening on the surface and a cavity inside. The inner width of the chute is greater than the width of the opening. The cross section of the chute is in the shape of a "concave". , wherein, the lower slider is located inside the chute; the upper slider is located above the lower slider and outside the chute, the upper slider and the lower slider are connected by pipes, and the feed port of the extruder is arranged on the chute , the feeding port is located at the bottom of the chute, the upper slider and the lower slider are passed through by the pipe, and the pipe connects the feeding port and the hopper, so that when it is necessary to change the material type in the hopper, the hopper will be removed from the feeding port The position of the hopper moves outward along the chute so that the through hole of the lower slider can be connected with the discharge hole, and the hopper body can be cleaned well, the material can be discharged from the discharge hole, and the required material can be filled. The hopper body is removed, which avoids high-intensity labor and does not need to turn over the hopper body. Compared with the traditional structural form in which the hopper is fixed on the extruder, it solves the difficulty of changing material types, material residues, and labor intensity of workers. problem, to achieve the purpose of quick replacement
