Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a low-energy-consumption and environmentally friendly double-layer extruder. Background Technology

[0002] A double-layer extruder is a rubber processing equipment that combines two different types of rubber or the same material in different colors through co-extrusion to form a double-layer structure product. In rubber extrusion molding equipment, the rubber extruder is usually called the main machine, while the downstream equipment that is matched with it, the rubber extrusion molding machine, is called the auxiliary machine. The rubber extruder can be matched with various rubber molding auxiliary machines such as pipes, films, monofilaments, and strapping to produce a variety of rubber products.

[0003] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0004] Existing extruders heat raw materials to a molten state through a hot-melt mechanism, and then extrude the molten rubber through an extrusion mechanism. However, the raw materials are heated while being conveyed in the equipment, which can easily lead to uneven melting and reduce the quality of the rubber products.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a low-energy-consumption and environmentally friendly double-layer extruder, which solves the problem that traditional double-layer extrusion mechanisms, which directly add raw material particles and then perform hot-melt treatment, are prone to uneven melting, resulting in a reduction in the quality of rubber processed products.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A low-energy-consumption and environmentally friendly double-layer extruder includes a base, a drive mechanism fixedly installed at one end of the base, a crushing cylinder body fixedly installed on the top of the drive mechanism, the crushing cylinder body being inclined at 15 degrees to the other end, a feed inlet opening on one side of the top of the crushing cylinder body, a second servo motor fixedly installed at one end of the crushing cylinder body, a crushing roller fixedly connected to the output end of the second servo motor being rotatably installed inside the crushing cylinder body, and a discharge pipe being fixedly installed through the other side of the bottom of the crushing cylinder body.

[0009] Preferably, a first servo motor that is fixedly connected to the drive mechanism is fixedly installed on the top of one side of the base, and a feed hopper is fixedly installed on the top of the feed inlet.

[0010] Preferably, a double-layer extrusion mechanism is fixedly installed on the top of the base and fixedly connected to the drive mechanism. The discharge pipe is connected through the double-layer extrusion mechanism. An extrusion head is provided through the other end of the double-layer extrusion mechanism, and the number of extrusion heads is two sets.

[0011] Preferably, a cooling mechanism is movably mounted on the other side of the top of the base, and a cooling machine body is fixedly mounted on the top of the cooling mechanism.

[0012] Preferably, a lead screw is rotatably mounted on the other end of the base via a bearing, a threaded collar is sleeved on the outer side of the lead screw, and a connecting rod is fixedly connected through the cooling mechanism and the threaded collar.

[0013] Preferably, a rotating handle is fixedly installed at the other end of the lead screw, and a main control box is fixedly installed at the rear end of the top of the base.

[0014] Compared with the prior art, this utility model provides a low-energy-consumption and environmentally friendly double-layer extruder with the following beneficial effects: This utility model adds rubber raw materials into the interior of the crushing cylinder body through the feed port, and drives the crushing roller to rotate through the second servo motor, so that the crushing blades on the surface of the crushing roller crush the rubber particles. Since the crushing cylinder body is tilted at 15 degrees to the other end, the crushed raw materials flow to the other end of the crushing cylinder body and are mixed evenly. The raw materials are discharged into the interior of the double-layer extrusion mechanism through the discharge pipe for rubber processing extrusion production. This avoids the problem that the traditional double-layer extrusion mechanism can easily cause uneven melting and reduce the quality of rubber products due to the direct addition of raw material particles and subsequent hot melting treatment.

[0021] 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.

[0022] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a low-energy-consumption and environmentally friendly double-layer extruder.

[0023] Please see Figures 1-5 A low-energy-consumption and environmentally friendly double-layer extruder includes a base 1. A drive mechanism 101 is fixedly installed at one end of the base 1. A crushing cylinder body 2 is fixedly installed on the top of the drive mechanism 101. A double-layer extrusion mechanism 103, which is fixedly connected to the drive mechanism 101, is fixedly installed on the top of the base 1. A discharge pipe 204 is connected through the double-layer extrusion mechanism 103. An extrusion head 104 is provided through the other end of the double-layer extrusion mechanism 103, and there are two sets of extrusion heads 104. A device fixedly connected to the drive mechanism 101 is fixedly installed on the top of one side of the base 1. The first servo motor 102 is connected, the crushing cylinder body 2 is tilted 15 degrees to the other end, the top of the crushing cylinder body 2 is provided with a feed port 201 on one side, the second servo motor 202 is fixedly installed at one end of the crushing cylinder body 2, the crushing roller 203 is rotatably installed inside the crushing cylinder body 2 and fixedly connected to the output end of the second servo motor 202, the discharge pipe 204 is fixedly installed through the other side of the bottom of the crushing cylinder body 2, the feed hopper 205 is fixedly installed at the top of the feed port 201, and the main control box 5 is fixedly installed at the rear end of the top of the base 1.

[0024] With the above-described structural configuration, when using this low-energy, environmentally friendly double-layer extruder, the main control box 5 controls the switch of the device. Then, feed pellets are added to the inside of the feed hopper 205, sliding down through the feed inlet 201 into the inside of the crushing cylinder body 2. Next, the output of the second servo motor 202 drives the crushing roller 203 to rotate, causing the crushing blades on the surface of the crushing roller 203 to crush the rubber pellets. Because the crushing cylinder body 2 is tilted 15 degrees to the other end, the crushed rubber raw material is conveyed to the other end, while the raw material is uniformly mixed. The raw material is then conveyed to the inside of the discharge pipe 204 through the discharge port at the other end of the crushing cylinder body 2. The material is then discharged into the interior of the double-layer extrusion mechanism 103. At this time, the first servo motor 102 drives the double-layer extrusion mechanism 103 to enter the working state through the drive mechanism 101 to perform heating and extrusion operations on the raw material. Since the rubber particles are more likely to enter the molten state after being crushed, the rubber can be processed and extruded more evenly. Since the double-layer extrusion mechanism 103 is a double extrusion mechanism, two sets of processed rubber products are extruded from the extrusion head 104, which improves the processing efficiency of the device and solves the problem that the traditional double-layer extrusion mechanism 103 is prone to uneven melting after directly adding the raw material particles and performing hot melt treatment, which leads to a reduction in the quality of rubber processed products.

[0025] Furthermore, a cooling mechanism 3 is movably installed on the other side of the top of the base 1, and a cooling machine body 301 is fixedly installed on the top of the cooling mechanism 3. The extruded rubber product enters the interior of the cooling mechanism 3 and is cooled by the cooling machine body 301, so that the rubber product is quickly cooled and shaped, thereby improving the production efficiency of the rubber product.

[0026] Furthermore, a lead screw 4 is rotatably mounted on the other end of the base 1 via a bearing. A handle 401 is fixedly mounted on the other end of the lead screw 4. A threaded collar 402 is sleeved on the outer side of the lead screw 4. A connecting rod 403 is fixedly connected between the cooling mechanism 3 and the threaded collar 402. When the inlet and outlet of the extrusion head 104 and the cooling mechanism 3 need to be cleaned, the handle 401 is rotated to make the lead screw 4 rotate inside the base 1. At this time, the threaded collar 402 moves to the other end on the outer side of the lead screw 4. The connecting rod 403 drives the cooling mechanism 3 to move to the other end, thereby moving the inlet of the cooling mechanism 3 away from the extrusion head 104. This makes it easier for workers to clean the inlet of the extrusion head 104 and the cooling mechanism 3, and prevents the accumulation of impurities in the extrusion head 104 and the cooling mechanism 3 during long-term operation, which would affect the production of rubber products.

[0027] Working principle:

[0028] The working principle of this low-energy and environmentally friendly double-layer extruder is as follows: First, the main control box 5 is started to open the equipment, and rubber raw material granules are poured into the feed hopper 205, which slides into the crushing cylinder body 2 at a 15-degree inclination through the feed inlet 201. The second servo motor 202 drives the crushing roller 203 to rotate, and the crushing blades on its surface efficiently crush the rubber granules. The crushed raw material is conveyed towards the discharge pipe 204 under the action of the inclined structure, and preliminary mixing is completed in this process. After the raw material enters the double-layer extrusion mechanism 103 through the discharge pipe 204, the first servo motor 102 drives the double-layer screw to rotate through the drive mechanism 101. The crushed raw material is easier to melt due to its uniform particle size. The double-layer screw design allows the two sets of raw materials to be extruded simultaneously, forming a double-layer structure product through the two sets of extrusion heads 104. The main body of the cooler 301 rapidly cools and shapes the extruded products. When cleaning is required, rotating the handle 401 drives the lead screw 4 to rotate, causing the threaded collar 402 to rotate and move to the other end. The threaded collar 402 pushes the main body of the cooler 301 horizontally through the connecting rod 403, completely separating the extrusion head 104 from the inlet of the cooling mechanism 3. This facilitates thorough cleaning of residual impurities inside the equipment, ensuring the stability of product quality during continuous production. The entire process, through the synergistic effect of crushing pretreatment and the double-layer extrusion structure, effectively solves the technical problem of uneven melting in traditional equipment. Furthermore, the modular design facilitates maintenance.
