Description

Technical Field

[0001] This utility model relates to the field of plastic granulator technology, specifically to a conveying mechanism for a plastic granulator. Background Technology

[0002] A plastic granulator is a device for recycling waste plastics. It mainly consists of a heating system for heating and melting the waste plastics and extruding them into strips, a cooling system for cooling the extruded plastic strips, and a crushing system for breaking the cooled plastic strips into smaller pieces.

[0003] Currently, when plastic granulators cool the extruded plastic strips, they usually extrude multiple plastic strips into a water tank for cooling. However, when a plastic strip breaks, the subsequently extruded plastic strips accumulate in the water tank and gradually solidify. It is necessary to reheat and melt the solidified and bent plastic strips, which affects the processing efficiency. Therefore, a conveying mechanism for a plastic granulator is provided. Utility Model Content

[0004] The purpose of this invention is to provide a conveying mechanism for a plastic granulator to solve the problem that when a plastic strip breaks, the subsequently extruded plastic strips accumulate in the water tank and gradually solidify, requiring the solidified and bent plastic strips to be reheated and melted, which affects processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying mechanism for a plastic granulator, comprising:

[0006] Granulator body;

[0007] A cooling water tank is located at the discharge end of the granulator body and is used to cool the plastic strips.

[0008] A tracked conveyor is installed at the bottom of the cooling water tank;

[0009] Several strip-shaped damping blocks are provided and evenly distributed on the track conveyor device;

[0010] Several U-shaped openings are provided and evenly distributed on the strip-shaped damping block, and plastic strips are placed inside the U-shaped openings;

[0011] A traction assembly, located at the discharge end of the cooling water tank, is used to move the plastic strip.

[0012] Preferably, the traction assembly includes fixed blocks arranged opposite to each other at the discharge end of the cooling water tank, two rotating rods rotatably mounted between the two fixed blocks, several pairs of traction rollers arranged opposite each other on the side walls of the two rotating rods, gears meshing with each other at the shaft ends of the two rotating rods, and the shaft end of the lower rotating rod being synchronously rotatably connected to the shaft end of the track conveyor.

[0013] Preferably, a first transmission roller is provided at the shaft end on the side of the lower rotating rod away from the gear, and a second transmission roller is provided at the shaft end of the track conveyor. A transmission belt is provided between the first transmission roller and the second transmission roller, and the first transmission roller and the second transmission roller have the same diameter.

[0014] Preferably, the discharge end of the cooling water tank is set as an inclined surface, and the included angle between the bottom surface of the cooling water tank and the inclined surface is not less than 135 degrees.

[0015] Preferably, the inclined surface of the discharge end of the cooling water tank is provided with a plurality of guide slides adapted to the traction component, and the opening spacing of the guide slides decreases step by step as they approach the traction component.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The conveying mechanism of this utility model for a plastic granulator, in use, uses a crawler conveyor device in conjunction with a traction component to convey plastic strips. When a plastic strip breaks after entering the cooling water tank, several strip-shaped damping blocks on the crawler conveyor device increase the resistance between the plastic strip and the conveyor, thereby enabling the plastic strip to continue to be conveyed. This avoids the problem that the plastic strips extruded later will accumulate in the water tank and gradually solidify, requiring the solidified and bent plastic strips to be reheated and melted, thus ensuring the processing efficiency of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a conveying mechanism for a plastic granulator, including a granulator body 1 for heating and melting waste plastic and extruding it into strips; a cooling water tank 2 disposed at the discharge end of the granulator body 1 for cooling the plastic strips; a crawler conveyor 3 disposed at the bottom of the cooling water tank 2; several strip-shaped damping blocks 4 disposed and evenly distributed on the crawler conveyor 3; several U-shaped openings 5 ​​disposed and evenly distributed on the strip-shaped damping blocks 4, the U-shaped openings 5 ​​being used to place the plastic strips; and a traction assembly 6 disposed in the cooling water tank 2. The discharge end is used to pull the plastic strips. During use, when the plastic granulator body 1 extrudes multiple plastic strips into the cooling water tank 2 for cooling, the crawler conveyor 3 is activated in conjunction with the traction component 6 to transport the plastic strips. When the plastic strips break in the cooling water tank 2, the damping effect of several strip-shaped damping blocks 4 on the crawler conveyor 3 drives the plastic strips to continue being transported. This avoids the problem that the plastic strips extruded later will accumulate in the water tank and gradually solidify, requiring the solidified and bent plastic strips to be reheated and melted, thus ensuring the processing efficiency of the equipment.

[0024] Specifically, the traction assembly 6 includes fixed blocks 6-1 arranged opposite to the discharge end of the cooling water tank 2. Two rotating rods 6-2 are rotatably mounted between the two fixed blocks 6-1. Several pairs of traction rollers 6-3 are arranged opposite to each other on the side walls of the two rotating rods 6-2. The rotating shaft ends of the two rotating rods 6-2 are equipped with gears 6-4 that mesh with each other. The rotating shaft end of the lower rotating rod 6-2 is synchronously connected to the rotating shaft end of the track conveyor 3. In use, the rotating shaft end of the track conveyor 3 drives the lower rotating rod 6-2 to rotate synchronously, so that the rotation direction of the lower rotating rod 6-2 is the same as the conveying direction of the track conveyor 3. At the same time, the lower rotating rod 6-2 drives the lower gear 6-4 to rotate, and the lower gear 6-4 drives the upper gear 6-4 and the rotating rod 6-2 to rotate in opposite directions, so that the two traction rollers 6-3 arranged opposite to each other on the two rotating rods 6-2 rotate first, so that the plastic strip enters between the two traction rollers 6-3 for traction.

[0025] Specifically, a first transmission roller 7 is provided at the shaft end of the lower rotating rod 6-2 on the side away from the gear 6-4, and a second transmission roller 8 is provided at the shaft end of the track conveyor 3. A transmission belt 9 is provided between the first transmission roller 7 and the second transmission roller 8. The first transmission roller 7 and the second transmission roller 8 have the same diameter. In use, the track conveyor 3 is started to drive the second transmission roller 8 to rotate. The second transmission roller 8 drives the first transmission roller 7 to rotate through the transmission belt 9, thus realizing the starting of the track conveyor 3 to drive the traction component 6 to rotate. At the same time, since the first transmission roller 7 and the second transmission roller 8 have the same diameter, the synchronous rotation of the first transmission roller 7 and the second transmission roller 8 realizes that the conveying speed of the track conveyor 3 is the same as the traction speed of the traction component 6.

[0026] Specifically, the discharge end of the cooling water tank 2 is set as an inclined surface, and the included angle between the bottom surface of the cooling water tank 2 and the inclined surface is not less than 135 degrees. By setting the discharge end of the cooling water tank 2 as an obtuse-angled inclined surface, when the broken end of the plastic strip comes into contact with the inclined surface, it can effectively prevent the broken end of the plastic strip from hitting and getting stuck with the inclined surface, ensuring that the broken end of the plastic strip moves along the inclined surface of the cooling water tank 2 after contacting the inclined surface, thus ensuring the smoothness of the equipment's conveying of the plastic strip.

[0027] Specifically, the inclined surface of the discharge end of the cooling water tank 2 is provided with several guide slides 10 adapted to the traction component 6. The opening spacing of the guide slides 10 gradually decreases as they approach the traction component 6. The guide slides 10 are narrower at the top and wider at the bottom, and the bottoms of two adjacent guide slides 10 are connected. When the plastic strip moves upward along the inclined surface of the discharge end of the cooling water tank 2 and its position deviates, the broken end of the plastic strip will contact the side wall of the guide slide 10, and the plastic strip will slide along the side wall of the guide slide 10 during its forward movement. The guide channel 10 guides the plastic strip to the correct position and into the traction component 6, thus realizing the reintroduction of the broken end of the plastic strip into the traction component 6 for retraction through the guide slide 10.

[0028] Working principle: When the plastic granulator body 1 extrudes multiple plastic strips into the cooling water tank 2 for cooling, the crawler conveyor 3 is activated in conjunction with the traction component 6 to transport the plastic strips. The strip-shaped damping block 4 on the crawler conveyor 3 ensures that the broken plastic strips continue to be transported.
