Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a feeding mechanism for degradable plastic particles. Background Technique

[0002] Degradable plastics refer to a type of plastics whose various properties of products can meet the use requirements, remain unchanged during the storage period, and can be degraded into environmentally harmless substances under natural environmental conditions after use. Therefore, they are also called environmentally degradable plastics. Degradable plastic particles are semi-finished products in the plastic processing industry and can be further processed into plastic products such as plastic bags. A feeding mechanism is required when adding plastic particles to an injection molding machine.

[0003] Chinese Utility Model Publication No.: CN215396501U includes a feeding housing. The four corners of the lower end face of the feeding housing are fixed to support columns. The feeding housing is a frame structure with a rectangular cross-section. One end of the feeding housing is fixedly connected to a motor carrier plate. The motor carrier plate is fixedly connected to a driving motor. The output shaft of the driving motor passes through one end of the feeding housing and is fixedly connected to a feeding rod. The outer circumference of the crushing rotating shaft is fixedly connected to a crushing rod. The lower end face of the crushing box body is fixedly connected to a filter screen plate, and the lower end face of the filter screen plate is flush with the feeding groove opened on the upper end face of the feeding housing. The end of the feeding housing away from the motor carrier plate is communicated with a discharge pipe. Compared with the prior art, the utility model has the following beneficial effects: it realizes the dispersion of plastic particles bonded together and increases the melting efficiency of plastic particles.

[0004] The applicant found that there are some deficiencies in the use of this patent: this patent uses a limiting rod to insert the limiting rod into the ground to avoid the phenomenon of the feeding housing moving during the feeding process. However, when the ground is a hard cement floor, the limiting rod is not easy to insert into the ground, and the feeding housing is still prone to instability.

[0005] Therefore, the utility model designs a feeding mechanism for degradable plastic particles to solve the problems existing in the prior art. Content of the Utility Model

[0009] Preferably, the moving assembly includes a receiving groove, the receiving groove is opened at the bottom of the conveying box, a lifting plate is slidably installed in the receiving groove, moving wheels are arranged at four corners of the bottom of the lifting plate, an electric push rod is installed on the inner wall of the top of the U-shaped frame, an output end of the electric push rod penetrates through the base and is connected to the top of the lifting plate. When feeding, the electric push rod drives the lifting plate to rise, so that the moving wheels enter the receiving groove, and the bottom of the base contacts the ground, thereby improving the stability of the base and preventing the discharge pipe from shifting.

[0010] Preferably, a handrail is installed on one side of the top of the base, and the handrail facilitates the staff to push the base to move.

[0011] Preferably, rubber anti-slip pads are arranged on both sides of the bottom of the base, and the rubber anti-slip pads can increase the friction between the base and the ground and improve the stability.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. With the settings of the base and the moving component in the present utility model, during the feeding process, the bottom of the base contacts the cement floor. Due to the large contact area, the friction is also large, and the base is not easily displaced, avoiding the deviation of the discharge pipe. When it is necessary to move, the electric push rod drives the lifting plate to descend so that the moving wheels come into contact with the ground, and the base leaves the ground, and the staff can then move the base;

[0015] 2. With the settings of the dispersing blades and the driving component in the present utility model, during the rotation of the conveying shaft, the rotating shaft is rotated through the belt and the belt pulley. The rotating shaft drives the dispersing blades to disperse the agglomerated plastic particles in the feeding hopper, avoiding affecting the subsequent processing effect of the plastic particles. Through the transmission of the belt and the belt pulley, the use of one motor is saved. BRIEF DESCRIPTION OF THE DRAWINGS
