Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a melting device for recycling plastic particles. Background Art

[0002] Plastic is an important organic synthetic polymer material. It is a material or plastic material product that can be molded into various shapes and can maintain its shape. It has good transparency and wear resistance and is widely used.

[0003] The existing plastic particles are of different sizes. When they are poured into the hopper of the melting machine for melting, some larger plastic particles are easily stuck in the hopper to form a blockage, which affects the processing efficiency of the plastic particles.

[0004] The reason for this problem is that, in order to reduce the pollution of plastic waste, plastic products are recycled for secondary processing. When the plastic is recycled for secondary processing, it will be cut and crushed first, and then melted in the hopper of the melting machine. Due to the different hardness of plastic products, it is easy to cause uneven cutting and crushing of the plastic. As a result, when pouring plastic particles, the plastic particles will quickly fall into the hopper. Some longer and larger plastic particles are easy to get stuck in the hopper and form a blockage, affecting the processing efficiency of the plastic particles. In view of the shortcomings of the existing technology, we propose a melting device for plastic particle recycling to solve the above problems. Utility Model Content

The side wall of the hopper 101 is provided with a screening mechanism 2. The screening mechanism 2 includes:

[0031] The specific functions and operation of the plastic melting machine 1 can refer to the straight-cut plastic granulating unit of model GG2-130;

[0032] The screen 3 and the material box 201 are arranged inside the hopper 101, and the screen 3 and the material box 201 are used to screen the plastic particles;

[0033] The movable plate 4 and the clamping plate 5 are arranged inside the material box 201 and used to adjust the spacing of the material boxes 201 . The clamping plate 5 is arranged on the side wall of the hopper 101 and the side wall of the hopper 101 is used to limit the material box 201 and the movable plate 4 .

[0035] The inner wall of the material box 201 is fixedly connected with a square bar 203 , and two sides of the movable plate 4 are provided with sliding grooves 401 , and the square bar 203 is slidably connected inside the sliding grooves 401 .

[0036] The screening mechanism 2 also includes:

[0037] A vibration motor 301 is arranged at the bottom of the screen 3, and the vibration motor 301 is used to move the screen 3;

[0038] The specific functions of the vibration motor 301 can refer to the miniature double-headed fan-shaped strong vibration motor model R-555.

[0039] The screw rod 501 is rotatably connected to the bottom of the clamping plate 5 , and the clamping plate 5 is used to move the clamping plate 5 .

[0040] The inner wall of the material box 201 is fixedly connected with a fixed plate 202, a vibration motor 301 is fixedly connected to the top of the fixed plate 202, and a screen 3 is fixedly connected to the top of the vibration motor 301. The screen 3 can be driven to vibrate by the vibration motor 301, so that the recycled plastic particles can be easily filtered through the screen 3, thereby preventing larger plastic particles from being easily stuck in the feed hopper 101, causing the feed hopper 101 to be blocked and affecting the processing efficiency.

[0041] The side wall of the feed hopper 101 is provided with a limiting groove 103, and the card plate 5 is slidably connected inside the limiting groove 103.
