The secondary drying method can dry the plastic particles entering the extrusion machine more thoroughly, reduce the bubbles in the insulating layer of the formed cable, and improve the product quality. However, the drying method of plastic particles in the existing CN210026220U patent is too simple and the drying effect is not good. By setting a stirring blade assembly to prevent plastic particles from sticking, but no screen is set below the stirring blade assembly for effective interception.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0022] Next, the embodiments of the present utility model will be described according to its overall structure.

[0023] Please refer to Figures 1 - 3, An auxiliary feeding device for an extrusion equipment, including a crushing barrel 1, a water filling barrel 11 and a feeding bin 16. The top of the crushing barrel 1 is integrally provided with a feeding pipeline 2, and a baffle 3 is welded to the inner wall of the feeding pipeline 2. A support rod 4 is fixed below the baffle 3, and the baffle 3 is arranged in an inclined structure. By injecting raw materials into the crushing barrel 1 through the feeding pipeline 2, the raw materials are processed inside the crushing barrel 1. With the setting of the baffle 3, it can prevent the raw materials from spraying out of the crushing barrel 1 during the crushing process. The setting of the support rod 4 enhances the stability of the baffle 3. Inside the crushing barrel 1, there is a main rod 5, and crushing rods 6 are welded and distributed on the surface of the main rod 5. The lower end of the main rod 5 is connected to a first motor 7, and the lower end of the main rod 5 passes through the bottom end of the crushing barrel 1 through a bearing and is fixedly connected to the output end of the first motor 7. And the crushing rods 6 are symmetric about the central axis of the main rod 5. Starting the first motor 7 drives the main rod 5 to rotate, so that the crushing rods 6 rotate at a high speed, which is convenient for crushing and stirring the raw materials, making the large pieces of raw materials broken into small pieces and reducing the subsequent thermoplasticity difficulty. Inside the crushing barrel 1, there is a screen 8. The outer side of the top end of the main rod 5 is rotatably connected to a ring 9, and the outer side of the ring 9 is fixed to one end of a connecting rod 10, and the other end of the connecting rod 10 is fixed to the inner wall of the crushing barrel 1. Through the setting of the ring 9 and the connecting rod 10, the shaking amplitude of the top end of the main rod 5 during high-speed rotation is reduced, thereby improving the stability of the main rod 5. The main rod 5 passes through the screen 8 through a bearing, and the central axis of the screen 8 coincides with the central axis of the crushing barrel 1. The screen 8 is used to intercept large-particle raw materials, so as to ensure that the raw materials discharged from the first discharge pipeline 15 are all small particles, which is convenient for subsequent raw material thermoplasticity;

[0024] The water filling barrel 11 is arranged outside the crushing barrel 1, and an electric heating tube 12 is fixedly installed inside the water filling barrel 11. The top of the water filling barrel 11 is integrally provided with a water inlet 13, and the left lower end of the water filling barrel 11 is provided with a drain pipe 14. The bottom of the water filling barrel 11 is fixed with a first discharge pipeline 15;

[0025] The feeding bin 16 is arranged below the water filling barrel 11. Inside the feeding bin 16, there is a through rod 17. A spiral blade 18 is wound around the surface of the through rod 17, and a second motor 19 is arranged at the top end of the through rod 17. Below the top end of the feeding bin 16, a second discharge pipeline 20 is welded. The lower end of the first discharge pipeline 15 is inserted into the feeding bin 16, and the top end of the through rod 17 passes through the top end of the feeding bin 16 through a bearing and is connected to the output end of the second motor 19. The raw materials enter the feeding bin 16 through the first discharge pipeline 15. Under the action of the second motor 19, the through rod 17 drives the spiral blade 18 to rotate, and the rotating spiral blade 18 pushes the raw materials to move until the raw materials are discharged from the second discharge pipeline 20.

[0026] Working principle: When in use, inject raw materials into the inside of the crushing barrel 1 through the feeding pipeline 2. Then, start the first motor 7 through the controller. The first motor 7 drives the main rod 5 and the crushing rod 6 to rotate at a high speed, facilitating the crushing and mixing of the raw materials, so that large pieces of raw materials are broken into small pieces. Inject clear water into the water filling barrel 11 through the water inlet 13. Then, energize the electric heating tube 12. The electric heating tube 12 heats the clear water inside the water filling barrel 11, causing the temperature inside the crushing barrel 1 to rise, thereby dehydrating and drying the raw materials inside the crushing barrel 1. The raw materials that have been broken into small particles pass through the sieve mesh 8 and the first discharge pipeline 15 and enter the inside of the feeding bin 16. The controller starts the second motor 19. The second motor 19 drives the through rod 17 and the spiral blade 18 to rotate. The rotating spiral blade 18 pushes the raw materials upward until the raw materials are pushed out from the second discharge pipeline 20 and fall into the extrusion equipment. In this way, the feeding process of the raw materials is completed.

[0027] The control mode of this device is automatically controlled through the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art and belongs to the common general knowledge in this field. Therefore, the control mode and circuit connection of this device will not be explained in detail.
