Description

Technical Field

[0001] This utility model relates to the field of material forming technology, and in particular to a waterproof material board forming extrusion device. Background Technology

[0002] Waterproof material boards are a type of board that can prevent water penetration. They are widely used in many fields such as construction, water conservancy, and underground engineering. Their main function is to form a barrier through their physical structure and material properties to prevent water from seeping from one side to the other.

[0003] The manufacture of waterproof materials requires the addition of various raw materials with different particle sizes. However, the current extrusion equipment lacks a pretreatment process for the raw material particles. This results in inconsistent transmission rates of different raw materials within the screw, which can easily lead to an imbalance in raw material distribution. This negatively impacts the molding quality and final effect of the waterproof material board, causing the product to fail to meet the expected waterproof performance and physical property standards. This severely restricts the improvement of production efficiency and product quality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a waterproof material board forming extrusion device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof material board forming extrusion device, comprising a barrel, a servo motor, and a screw. The top surface of the barrel is connected to a conical hopper, and a spiral cutter is rotatably connected to the inner wall of the conical hopper. A conical gear set is provided at the top of the conical hopper. The central shaft of the spiral cutter passes through the top wall of the conical hopper and is fixedly connected to one end of the conical gear set. The other end of the conical gear set is connected to a conveyor belt. One end of the conveyor belt is drivenly connected to a rotating shaft. The output end of the servo motor is connected to the rotating shaft, and the other end of the rotating shaft is fixedly connected to the screw.

[0006] Preferably, the outer wall of the conical hopper is connected to a feed hopper, the output end of the servo motor is fixedly connected to a reducer, and the servo motor is fixedly connected to the rotating shaft through the reducer.

[0007] Preferably, a base is provided below the bottom end of the material cylinder, and a stand is fixedly connected to the top surface of the base.

[0008] Preferably, the upright is fixedly connected to the outer wall of the material cylinder.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a spiral blade in the conical hopper, the spacing between the blades gradually becomes denser from top to bottom, and the width of the blades gradually decreases from top to bottom. This can cut raw materials and additives of different particle sizes to a certain size range, effectively solving the problem of mixing caused by differences in particle size. This allows the materials to be mixed more thoroughly in the barrel, thereby improving the quality of the waterproof board and ensuring the stability and reliability of its performance.

[0014] 2. In this utility model, a heating device is set on the inner wall of the material cylinder to form a temperature gradient difference, which promotes the full mixing and melting of the raw materials.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1-4 As shown, this utility model provides a waterproof material board forming extrusion device, including a barrel 2, a servo motor 6 and a screw 12. The top surface of the barrel 2 is connected to a conical hopper 10. A spiral cutter 13 is rotatably connected to the inner side wall of the conical hopper 10. A bevel gear set 8 is provided at the top of the conical hopper 10. The central shaft of the spiral cutter 13 passes through the top wall of the conical hopper 10 and is fixedly connected to one end of the bevel gear set 8. The other end of the bevel gear set 8 is connected to a conveyor belt 11. One end of the conveyor belt 11 is drivenly connected to a rotating shaft 14. The output end of the servo motor 6 is connected to the rotating shaft 14. The other end of the rotating shaft 14 is fixedly connected to the screw 12.

[0024] The specific setup and function of this embodiment will be described in detail below. Generally, polymer materials are used to make waterproof material boards. This article takes polyvinyl chloride (PVC) waterproof board as an example. PVC resin and various additives (such as stabilizers, plasticizers, etc.) are put into the conical hopper 10. Through the interaction of the screw 12 and the barrel 2, the large particles are divided into small particles and continue to move forward with the rotation of the screw 12 until they are extruded from one end of the discharge plate 3. A heating device is set on the inner wall of the barrel 2 to ensure the temperature gradient difference inside the barrel 2, so that the above raw materials are fully mixed and melted to form a molten waterproof material. A mold for manufacturing the board is connected at the discharge plate 3. The specifications and dimensions of the mold can be changed as needed for the installation reagents. After a period of time, the molten raw material in the mold can form a whole waterproof material board. Because the raw materials and various additives used in the production of waterproof membrane have different particle sizes, their throughput in the screw 12 varies, resulting in insufficient mixing of the raw materials and additives. Before entering the inner cavity of the barrel 2, a rotatable spiral cutter 13 is installed in the conical hopper 10. The spiral cutter 13 consists of a central shaft and blades. The blades gradually become denser from top to bottom, and the width of the blades gradually decreases from top to bottom. The spiral cutter 13 can cut materials of different particle sizes into a certain size range, so that the raw materials and additives can be mixed more evenly in the barrel 2, thereby improving the quality of the waterproof membrane produced.

[0025] Example 2: Figure 1 and Figure 4 As shown, the outer wall of the conical hopper 10 is connected to the feed hopper 9. The output end of the servo motor 6 is fixedly connected to the reducer 5, and the servo motor 6 is fixedly connected to the rotating shaft 14 through the reducer 5. A base 1 is provided below the bottom of the material cylinder 2, and a stand 4 is fixedly connected to the top surface of the base 1. The stand 4 is fixedly connected to the outer wall of the material cylinder 2. The other end of the material cylinder 2 is fixedly connected to the discharge plate 3, and the surface of the discharge plate 3 is evenly covered with through holes. A fixing frame 7 is fixedly connected to the top of the base 1, and the bevel gear set 8 is rotatably connected to the fixing frame 7 through a shaft. The outer wall of the material cylinder 2 is wrapped with an insulation layer, and a heater is provided on the inner wall of the material cylinder 2.

[0026] The overall effect of this embodiment is that, in order to save on the cost of using the motor, the servo motor 6 drives the reducer 5 to rotate, which in turn drives the rotating shaft 14 to rotate. The rotating shaft 14 can drive the screw 12 to select, so that the fixed material in the barrel 2 is squeezed forward. On the other hand, it drives the bevel gear set 8 to rotate through the conveyor belt 11, so that the bevel gear set 8 rotates the spiral cutter 13 through the central shaft. Therefore, when the servo motor 6 is started, it can drive the screw 12 to rotate and push the material, and drive the spiral cutter 13 to rotate and cut the material, thus reducing the cost of using the motor.

[0027] The method of use and working principle of this device: First, put PVC resin and various additives into the conical hopper 10;

[0028] Then, the servo motor 6 is started, which drives the reducer 5 to rotate, thereby causing the rotating shaft 14 to rotate. The rotating shaft 14 drives the bevel gear set 8 to rotate through the conveyor belt 11, thereby causing the spiral cutter 13 to rotate. It can cut materials of different particle sizes to a certain size range so that they can be more easily mixed in subsequent processes.

[0029] Next, the servo motor 6 drives the screw 12 to rotate via the rotating shaft 14, and the screw 12 extrudes the material in the barrel 2. Under the interaction of the two, the large particles are broken down into small particles and continue to move forward with the rotation of the screw 12. At the same time, the heating device on the inner wall of the barrel 2 ensures that there is a temperature gradient difference inside, which promotes the raw materials to be fully mixed and melted to form a molten waterproof material.

[0030] Finally, the molten raw material reaches the discharge plate 3 and is connected to the corresponding mold. The mold specifications and dimensions can be changed as needed. After a period of solidification, a whole waterproof board is formed.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
