Description

Technical Field

[0001] This utility model relates to the field of hot melting, and more specifically, to a plastic film hot melting feeding device. Background Technology

[0002] Plastics are high molecular weight compounds polymerized from monomers through addition or condensation reactions. They have moderate resistance to deformation, falling between fibers and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. In the production and processing of materials such as plastics, plastic films, and biodegradable materials, there are often some scraps. These remaining scraps can be recycled and reused, improving resource utilization and protecting the environment. However, in the processing of plastic raw materials such as thermoplastic film recycling and modification, a granulator is usually needed to make the recycled plastic into granules. The granulator melts the recycled film and other thermoplastics in the barrel of a hot melt machine.

[0003] The utility model patent with authorization announcement number CN 218700518 U relates to a feeding device, and more particularly to a plastic film hot-melt feeding device. A plastic film hot-melt feeding device includes a fixed frame, a motor frame, a servo motor, a first rotating shaft, and rollers. The motor frames are respectively fixed to the longitudinal ends on the right side of the fixed frame. The servo motor is fixed to one of the motor frames, and its output shaft is rotatably connected to the fixed frame. A first rotating shaft is located on the left side of the fixed frame, and is rotatably connected to the longitudinal ends on the left side of the fixed frame. The rollers are sleeved on and fixed to the first rotating shaft. Through the fixed frame, servo motor, and conveyor belt, the conveying of the plastic film is automated, reducing worker contact with the plastic film and thus reducing injuries to workers during production.

[0004] In the above-disclosed structure, the plastic film is received and conveyed by connecting the end box. However, it lacks an articulated protective hopper, which cannot be extended to directly enter the hot melt furnace. This can easily damage the conveyor belt, create gaps and cause material leakage, affecting stable conveying and resulting in poor adaptability. Furthermore, it lacks an adjustable scraper to clean the conveyor belt, which is not conducive to aligned collection and is prone to interference. Improvements are needed. Utility Model Content

It has high adaptability, is safe and stable, and avoids interference.

[0011] Furthermore, a square rod is fixedly connected to one side surface of the mounting plate, and a square block is slidably connected to the outer surface of the square rod.

In use, the mounting plate 1 is fixedly connected to the support leg 11, and the front end of the protective hopper 16 is inserted into the hot melt furnace. This can keep the end of the conveyor belt 14 away from the high temperature position to avoid damage, which is safe and efficient.

The clamping block 25 is slidably connected to one end surface of the arc-shaped rod 21 and is clamped to one end of the buffer spring 22. The clamping block 25 is located on one side of the mounting plate 1. By installing the combination screw and the clamping block through the combination holes on the arc-shaped rod, the buffer spring can be clamped in combination, thereby adjusting the clamping length and changing the buffer strength, thus adjusting the vibration amplitude. It has high adaptability, is safe and stable, and avoids interference. The clamping block 25 is connected to the combination holes 23 at different positions and then fixed by the threaded combination screw 24. It is convenient and stable, and the position of the clamping buffer spring 22 can be adjusted to change the compression amount, thereby adjusting the vibration amplitude. It can also adjust the vibration amplitude of the protective hopper 16, avoid interference, and is safe, stable, and highly adaptable.
