Description

Technical Field

[0001] The utility model relates to the technical field of plastic belt production, and particularly relates to a plastic belt production device. Background Art

[0002] Plastic belts are usually used for packing and bundling items, and can also be called packing belts. Existing plastic packing belts are polypropylene packing belts. Polypropylene packing belts are an environmentally friendly packing belt with a light weight produced from polypropylene, and are used in fully automatic packing machines, semi-automatic packing machines, manual packing machines, etc. They are suitable for bundling cartons or trays with a weight ranging from several kilograms to hundreds of kilograms of relatively light objects.

[0003] In the prior art, for example, a granulator for plastic belt production disclosed in the utility model with the patent publication number CN220784815U. An inlet mechanism is provided at the top of the feeding place. Materials enter the inlet mechanism through the conveyor belt. The output shaft of the power motor is connected to the roller shaft in the barrel and drives the roller shaft to rotate. The power motor drives the inlet mechanism to press the materials conveyed by the conveyor belt into the inlet mechanism to achieve the feeding action. This granulator for plastic belt production allows operators to fill materials without contacting the inlet mechanism, effectively avoiding safety problems. At the same time, the pressure column of the feeding system can provide downward pressure. When it is inconvenient for materials to enter the inlet mechanism, the pressure provided by the pressure column and the cross-cutting steel can effectively cut the materials, facilitating them to fall into the barrel and improving work efficiency.

[0004] In actual use, after the materials are cut, they fall into the barrel. Larger materials require a longer time during the melting process, restricting production efficiency.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above defects. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a plastic belt production device that can effectively solve the above technical problems.

[0007] To achieve the purpose of the utility model, the following technical solution is adopted: A plastic belt production device includes an extrusion barrel, a feeding component for chopping raw materials, and a power component for driving the feeding component to operate.

[0008] The feeding component includes a crushing barrel. An inlet is fixedly installed on the outer wall of the crushing barrel, and a rotating tube is rotatably installed on the central axis of the crushing barrel. Cutting knives for chopping raw materials are evenly installed on the rotating tube, and rotatable balls are installed on the inner wall of the rotating tube.

[0009] Further, the power assembly includes: a moving frame symmetrically and fixedly installed with straight racks on the inner wall, the moving frame is slidably installed in a fixed track, a half gear meshing with the straight racks, and a mounting frame fixedly installed on the top of the moving frame. A vertical threaded rod is fixedly installed on the mounting frame.

[0010] Further, both sides of the cutting knife are cutting edges.

[0011] Further, the threaded rod is slidably installed inside the rotating tube, and a ball is slid in the thread groove on the threaded rod.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0021] As Figures 1 to 4 shown, a plastic belt production device of the present utility model includes: an extrusion barrel 1, the extrusion barrel 1 is fixed on a base through a support plate, a discharge port 2 fixedly installed on the extrusion barrel 1, a granulating device installed in the discharge port 2, a motor 5 for driving the extrusion barrel 1 to work, a conveyor belt 3 for conveying materials to a feeding assembly, a collector 4 located below the discharge port 2, water for cooling plastic pellets is contained in the collector 4, a feeding assembly for chopping raw materials, and a power assembly for driving the feeding assembly to operate.

[0022] The feeding assembly includes: a crushing cylinder 11, the crushing cylinder 11 is fixedly installed on the top of a heating device 13, the raw materials are melted in the heating device 13 after being chopped, the heating device 13 is fixedly installed on the outer wall of the extrusion barrel 1, and the melted raw materials enter the extrusion barrel 1 from the heating device 13 through a feeding pipe. An inlet 12 is fixedly installed on the outer wall of the crushing cylinder 11, the inlet 12 is aligned with the upper end of the conveyor belt 3, the conveyor belt 3 conveys the raw materials to the inlet 12, and then enters the crushing cylinder 11 through the inlet 12. A rotating pipe 14 is rotatably installed on the central axis of the crushing cylinder 11, the top of the rotating pipe 14 is rotatably installed on the inner wall of the top of the crushing cylinder 11, cutting knives 15 for chopping raw materials are uniformly installed on the rotating pipe 14, both sides of the cutting knives 15 are cutting edges, and when the rotating pipe 14 rotates forward or backward, the cutting knives 15 can cut the materials, cutting larger materials into small pieces. Rotating balls 16 are rotatably installed on the inner wall of the rotating pipe 14.

[0023] The power assembly includes a moving frame 8 with straight racks symmetrically and fixedly installed on its inner wall. The moving frame 8 is slidably installed in a fixed track 7, and the fixed track 7 is fixedly installed on the base to restrict the moving direction of the moving frame 8, enabling the moving frame 8 to move only in the vertical direction. The straight racks are engaged with a half gear 6, and the half gear 6 is fixedly installed on the rotating shaft of a motor 5. The rotation of the half gear 6 is driven by the rotating shaft of the motor 5. When the half gear 6 is engaged with the straight rack on one side of the moving frame 8, the moving frame 8 descends; when the half gear 6 is engaged with the straight rack on the other side of the moving frame 8, the moving frame 8 ascends. A mounting frame 9 is fixedly installed at the top of the moving frame 8, and a vertical threaded rod 10 is fixedly installed on the mounting frame 9. The moving frame 8 drives the threaded rod 10 to move in the vertical direction through the mounting frame 9. The threaded rod 10 is slidably installed inside a rotating tube 14, and a ball 16 slides in the thread groove on the threaded rod 10. When the mounting frame 9 drives the threaded rod 10 to slide down in the rotating tube 14, the ball 16 moves along the thread groove on the threaded rod 10, causing the rotating tube 14 to rotate forward and driving the cutting blade 15 to cut the material. When the mounting frame 9 drives the threaded rod 10 to slide up in the rotating tube 14, the rotating tube 14 drives the cutting blade 15 to rotate in reverse, which can effectively cut raw materials that are difficult to cut when the cutting blade 15 rotates forward.

[0024] The existing technology for plastic tape production is as follows: batching and mixing, heating and melting plastic pellets, extruding into water to form a tape embryo, heating and stretching for shaping, embossing, heating and cooling (shaping treatment), winding, packaging, and warehousing. During the process of heating and melting the material, larger materials require longer melting time to avoid affecting the quality of the plastic pellets. When heating and melting the material for a long time, it will affect the production efficiency. Therefore, by cutting and crushing the material and achieving a stirring effect during the cutting process to mix the material, the chopped material can melt quickly, reducing the melting time required. At the same time, the cutting blade 15 can rotate forward and backward, and materials that are not easily cut by the cutting edge on one side of the cutting blade 15 can be cut by the cutting edge on the other side, improving the chopping effect on the material.

[0025] Working principle: Start the motor 5. While driving the feeding cylinder to work, the motor 5 drives the half gear 6 to rotate. The half gear 6 drives the straight rack to move, causing the moving frame 8 to move up and down in the fixed track 7. The moving frame 8 drives the threaded rod 10 to slide up and down in the rotating tube 14 through the mounting bracket 9. By the movement of the ball 16 in the thread groove on the threaded rod 10, the rotating tube 14 drives the cutting knife 15 to rotate forward and backward. The material is cut into small pieces by the cutting edges on both sides of the cutting knife 15, enabling the material to melt faster, reducing the time required for melting, and improving work efficiency. The standard parts used in this utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings.
