Description

Technical Field

[0001] The utility model relates to the field of material bins for injection molding machines, in particular to a vibrating material bin for injection molding machines used for producing sandals. Background Art

[0002] Sandals are also a kind of slippers. As the name suggests, they are sandals, which are divided into flip-flops and inverted flops. Injection molding machines are needed in the production of sandals. The injection molding machine melts the raw materials of the sandals and squeezes them into the mold to form the prototype of the sandals. At present, when the raw materials of the sandals enter the injection molding machine, they need to be placed in the silo of the injection molding machine for feeding the injection molding machine. In order to ensure that the silo will not be blocked when unloading, a vibrator will be installed on the silo to form a vibrating silo, which can effectively prevent the raw materials from being compressed and accumulated in the silo.

[0003] For example, a Chinese utility model with the announcement number CN205820063U discloses a vibrating silo, including: a silo body supported and connected to a frame, the top of the silo body is open, a discharge port is arranged at the bottom of the silo body, a pair of vibration pumps are installed on the side wall of the silo body, the pair of vibration pumps are evenly arranged around the side wall of the silo body, the silo body and the frame are connected by an elastic shock absorbing mechanism, and the pair of vibration pumps can drive the silo body to vibrate vertically up and down on the frame. The advantages of the utility model are: a pair of vibration pumps can drive the silo body to vibrate vertically up and down on the frame, which can effectively prevent the powder material in the silo body from agglomerating or forming bridges, and greatly improve the smoothness of the powder material discharge; in addition, in the process of the silo body vibrating up and down, the elastic shock absorbing mechanism can absorb the vertical up and down vibration force of the silo body, which plays a good shock absorbing role on the silo body, thereby effectively preventing damage to the connection between the silo body and the frame.

[0004] In summary, although the silo can achieve the effect of vibration, there are still certain problems when using it. For example, the silo lacks a screening structure, and the raw materials of sandals are mostly plastic particles. The sizes of the plastic particles are different, and there will be some larger plastic particles. When the larger raw materials enter the injection molding machine, the melting speed is slow, which will result in incomplete melting, and it is easy to block the injection molding machine gun head. At the same time, the injection molding machine silo generally adopts the pouring method when loading. During the pouring process, the tiny particles in the raw materials will form dust, causing dust to spread in the workshop, seriously affecting the respiratory health of the staff.

By designing the main silo to be closed, a sleeve is connected to the top of the main silo. When the negative pressure fan inside the sleeve is working, the feed pipe at the top of the main silo can generate negative pressure, and external granular raw materials can be sucked into the main silo without generating dust when dumping the raw materials, thereby ensuring the cleanliness of the environment.

[0018] The utility model is further configured as follows: a clamping block is symmetrically bolted on the surface of the negative pressure fan, and the other side of the clamping block is bolted to the inner wall of the sleeve.

[0019] The negative pressure fan is fixed by adopting the above technical solution.

[0020] The utility model is further configured as follows: an end of the support spring away from the fixing seat is installed with a mounting seat through a fixing piece, and the mounting seat is bolted to the injection molding machine through bolts.

[0021] By adopting the above technical solution, it is convenient to fix the support spring on the top of the injection molding machine.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. The utility model installs a cavity at the bottom of the main silo, and a screening plate is installed inside the cavity. When the silo is vibrating, the material can be screened through the screening plate inside the cavity to prevent large materials that do not meet the size from entering the injection molding machine, thereby ensuring the normal hot melt operation of the injection molding machine;
