Description

Technical Field

[0001] This utility model relates to the field of silicone rubber product mixing technology, specifically to a mixing machine for processing silicone rubber products. Background Technology

[0002] A mixing machine is a specialized piece of equipment used to mix raw silicone rubber with various compounding agents. In order to improve the performance of silicone rubber products, improve the process and reduce costs, various compounding agents are often added to the raw rubber for mixing. The purpose is to use mechanical force to fully mix the raw rubber and compounding agents to form a compound with specific properties, providing a basic material for subsequent processing of silicone rubber products.

[0003] Existing mixing machines typically require manual feeding of raw materials. Manual operation makes it difficult to ensure that the amount and speed of raw materials fed in each time are completely consistent, resulting in increased batch-to-batch differences in the mixed rubber.

[0004] For example, the mixing device for producing silicone rubber products disclosed in patent CN208451975U does not have an automatic feeding function. It requires manual lifting of the material bucket and pouring it into the mixing chamber from the base material inlet. Manually lifting the material bucket and pouring it into the mixing chamber requires considerable physical strength, especially when the material bucket is heavy or when frequent feeding is required. This significantly increases the labor intensity of the operators. Furthermore, the speed and accuracy of manually pouring raw materials are limited by the operator's skills and physical strength, making it difficult to match the efficiency of automated equipment.

[0005] Therefore, it is necessary to invent a mixing machine for processing silicone rubber products to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a mixing machine for processing silicone rubber products, so as to solve the problem that the technology does not have an automatic feeding function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mixing machine for processing silicone rubber products, comprising a mixing tank, a conveyor belt, and a feeding box. A feed inlet is provided on one side of the upper part of the mixing tank, and a conveyor belt is provided on the rear side of the mixing tank. A feed hopper is provided at the bottom of the discharge end of the conveyor belt, and a feeding box is provided at the bottom of the feed hopper. A feeding box is provided on one side of the feeding box. A spiral shaft is horizontally arranged at the center of the inside of the feeding box, and spiral blades are provided on the spiral shaft. A discharge pipe is provided at the discharge end of the spiral blades and is located at one end of the bottom of the feeding box. The discharge end of the discharge pipe is directly opposite the feed inlet of the feed inlet.

[0008] Preferably, a support frame is provided below the mixing tank, and a discharge port is provided on one side of the bottom of the mixing tank to facilitate the discharge of the mixed material from the mixing tank.

[0009] Preferably, the mixing tank is equipped with an agitator inside, with both ends of the agitator rotatably mounted on the mixing tank. The rotation of the agitator ensures that the materials inside the mixing tank are fully mixed and stirred.

[0010] Preferably, a servo motor is installed on the outside of the mixing tank and located on a support frame. The output end of the servo motor is connected to the shaft end of the agitator. The agitator rotates at a constant speed through the drive of the servo motor.

[0011] Preferably, the feed hopper is connected to the feed box, and the feed box is connected to the delivery box, forming a complete raw material conveying path to ensure that the raw material can smoothly enter the feed box from the feed hopper and then be conveyed to the mixing tank through the delivery box.

[0012] Preferably, one end of the spiral shaft is rotatably mounted on the feeding box, and the other end of the spiral shaft is rotatably mounted on the feed box and extends to its outside, so that the raw materials are conveyed in the feeding box and the feed box through its rotation.

[0013] Preferably, a rotary motor is provided on the outer top surface of the feed box, a main pulley is provided at the output end of the rotary motor, and a driven pulley is provided on the shaft end of the spiral shaft that passes through the feed box. A transmission belt is tensioned on the main pulley and the driven pulley. The rotation of the rotary motor drives the main pulley to rotate, and then the power is transmitted to the driven pulley through the transmission belt, thereby driving the spiral shaft to rotate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention facilitates the initial conveying and stacking of raw materials through the installation of a conveyor belt. Used in conjunction with a feeding hopper, and with a spiral shaft and blades inside the feeding box, driven by a rotary motor, it achieves automatic material conveying. The interconnected design of the conveyor belt, feeding hopper, feeding box, and feeding hopper forms a complete raw material conveying path, ensuring that raw materials are smoothly conveyed from the conveyor belt to the feeding hopper, then into the feeding box, and finally to the mixing tank. This further guarantees the continuity and stability of automatic feeding. The continuous and stable supply of raw materials helps maintain the stability of the mixing process, not only improving the uniformity and consistency of the product, thus enhancing product quality, but also reducing the time and error of manual operation, making the addition of raw materials more accurate and timely, thereby improving mixing efficiency.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figures 1-5 The mixing machine shown includes a mixing tank 1, a conveyor belt 7, and a feeding box 10. A feed inlet 3 is provided on one side of the upper part of the mixing tank 1. The conveyor belt 7 is provided on the rear side of the mixing tank 1. A feed hopper 8 is provided at the bottom of the discharge end of the conveyor belt 7. A feeding box 9 is provided at the bottom of the feed hopper 8. A feeding box 10 is provided on one side of the feeding box 9. A spiral shaft 11 is horizontally arranged at the center of the inside of the feeding box 10. Spiral blades 12 are provided on the spiral shaft 11. A discharge pipe 17 is provided at the discharge end of the spiral blades 12 and is located at one end of the bottom of the feeding box 10. The discharge end of the discharge pipe 17 is directly opposite the feed end of the feed inlet 3.

[0025] In this embodiment, the conveyor belt 7 is used to transport raw materials into the feed hopper 8. The feed hopper 8 receives the raw materials falling from the conveyor belt 7 and guides them into the feed box 9 and the feeding box 10. The rotation of the spiral shaft 11 and spiral blades 12 inside the feeding box 10 transports the raw materials from one side of the feeding box 10 to the other side, so that the raw materials pass through the discharge pipe 17 into the mixing tank 1, realizing the automatic conveying of raw materials. The raw materials enter the mixing tank 1 at a uniform speed and quantity through the conveying of the spiral shaft 11 and spiral blades 12, which helps to achieve full mixing and uniform mixing of raw materials and improves the mixing effect.

[0026] A support frame 2 is provided below the mixing tank 1. A discharge port 4 is provided on one side of the bottom of the mixing tank 1. An agitator 6 is provided inside the mixing tank 1. Both ends of the agitator 6 are rotatably mounted on the mixing tank 1. A servo motor 5 is provided outside the mixing tank 1 and is located on the support frame 2. The output end of the servo motor 5 is connected to the shaft end of the agitator 6.

[0027] In this embodiment, the stirrer 6 rotates under the drive of the servo motor 5, which fully stirs and mixes the materials in the mixing tank 1, thereby improving the mixing effect.

[0028] The feed hopper 8 is connected to the feed box 9, and the feed box 9 is connected to the feeding box 10. One end of the spiral shaft 11 is rotatably mounted on the feeding box 10, and the other end of the spiral shaft 11 is rotatably mounted on the feed box 9 and extends to its outside. A rotary motor 13 is provided on the outer top surface of the feed box 9. A main pulley 14 is provided at the output end of the rotary motor 13. A driven pulley 15 is provided on the shaft end of the spiral shaft 11 that passes through the feed box 9. A transmission belt 16 is tensioned on the main pulley 14 and the driven pulley 15.

[0029] In this embodiment, the continuous and stable conveying of materials is achieved through the interconnected design of the feeding hopper 8, the feeding box 9 and the feeding box 10, and the rotation of the spiral shaft 11 driven by the rotary motor 13 in conjunction with the main pulley 14, the driven pulley 15 and the transmission belt 16. This design avoids interruption and accumulation of materials during the conveying process, and ensures that the materials enter the mixing tank 1 at a constant speed and direction, thereby improving production efficiency.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual appendix Figures 1-5 When using this invention, firstly, start the conveyor belt 7 to begin operation, and pour the raw material onto the conveyor end of the conveyor belt 7. As the conveyor belt 7 rotates, the raw material is conveyed above the feed hopper 8 and falls into the feed hopper 8. Therefore, the raw material falling into the feed hopper 8 will naturally flow into the feed box 9. At the same time as the raw material enters the feed box 9, start the rotary motor 13. The output end of the rotary motor 13 is equipped with a main pulley 14, which is connected to the driven pulley 15 on the screw shaft 11 through the transmission belt 16, thereby driving the screw shaft 11 to rotate. The rotation of the screw shaft 11 drives the screw... As the spiral blade 12 rotates, the raw material is conveyed in the feeding box 10 to the discharge end of the spiral blade 12, and falls into the inlet 3 of the mixing tank 1 through the discharge pipe 17. The discharge end of the discharge pipe 17 is directly opposite the inlet end of the inlet 3, ensuring that the raw material can enter the mixing tank 1 accurately and smoothly. After the raw material enters the mixing tank 1, the servo motor 5 is started, and the servo motor 5 drives the agitator 6 to rotate, which fully stirs and mixes the raw material in the mixing tank 1. Through the above operation steps, the mixer realizes the automatic feeding and mixing process of silicone rubber products, improving production efficiency and product quality.

[0032] The conveyor belt 7 mentioned above is an existing technology product, and its specific structure and function will not be described in detail here.
