Description

Technical Field

[0001] This invention relates to the field of geocell processing technology, specifically to extrusion equipment for producing geocells. Background Technology

[0002] A geocell is a civil engineering structure composed of a series of extruded sheets. Its main function is to reinforce soil, improve its stability and bearing capacity, prevent soil settlement and erosion, and reduce the impact of land settlement on buildings or other infrastructure. Geocells are generally composed of extruded sheets made of plastic materials such as PET, and the size and shape of these sheets can be adjusted according to actual needs. In practical engineering, geocells are typically laid on or below the soil surface, integrating with the soil to form a unified whole, thereby achieving the purpose of soil reinforcement.

[0003] Extrusion equipment for producing geocells is a technology used to manufacture geocell foundations. Its main technical background includes extrusion molding, materials mechanics, soil mechanics, control technology, and automation technology. Extrusion molding technology is a processing method for manufacturing shaped products. Its principle is to extrude raw materials through an extrusion machine to form them into a specific shape and size. Because extrusion molding has advantages such as high production efficiency, low production cost, and short production cycle, it is widely used in the field of geocell manufacturing.

[0004] In existing geocell production, molten plastic raw material is typically extruded directly into a mold to form the entire geocell. However, this method requires molds of specific lengths for geocells of varying lengths, making it unsuitable for producing geocells of different lengths and resulting in high equipment costs. Furthermore, it presents challenges in precisely adjusting the molding process for geocells of different lengths. Therefore, we offer extrusion equipment for geocell production. Summary of the Invention

[0005] The technical problem solved by this invention is:

[0006] (1) In the production of existing geocells, the molten plastic raw material is usually directly extruded into the corresponding mold, and then the entire plastic geocell is formed. However, this forming method requires geocells of different lengths, which requires molds of specific lengths. It is not suitable for forming geocells of different lengths, resulting in high equipment costs.

[0007] (2) At the same time, it is inconvenient to make precise adjustments when forming geocells of different lengths.

[0008] The present invention can be achieved by the following technical solution: an extrusion device for producing geocells, including a mounting platform, a forming cavity provided on the mounting platform, a feeding component provided on the mounting platform and the feeding component being located above the forming cavity, and a linear drive component for driving the feeding component to move horizontally on the mounting platform;

[0009] The bottom of the feeding component is provided with a discharge roller, the discharge roller is provided with a discharge groove, and the discharge groove is arranged along the circumference of the discharge roller. One end of the discharge roller is provided with a transmission gear, and the mounting platform is provided with a rack along the length direction of the forming cavity. The transmission gear and the rack are meshed and connected for transmission.

[0010] A further technical improvement of the present invention is that: the feeding component includes a feeding box, the feeding box is provided with a feeding pipe, the feeding pipe is located on the top side of the feeding box, and the feeding box is provided with multiple conveying components; each conveying component includes a conveying auger and a rotating rod, the multiple rotating rods are rotatably connected to the feeding box, the multiple conveying augers are respectively connected to one end of the multiple rotating rods, and the multiple conveying augers are vertically arranged in the feeding box, and the feeding box is provided with a drive motor for driving the multiple rotating rods to rotate.

[0011] A further technical improvement of the present invention is that: a conical groove is provided in the feeding box, a polymerization box is provided at the bottom end of the conical groove, the bottom end of the polymerization box is connected to the discharge box, and the bottom end of the discharge box is connected to the molding cavity, and the discharge roller is rotatably connected to the discharge box.

[0012] A further technical improvement of the present invention is that: the discharge box and the polymerization box are provided with a connected mounting threaded hole, and a threaded fixing rod is provided in the mounting threaded hole.

[0013] A further technical improvement of the present invention is that: the feeding box is provided with multiple air guide pipes, and the multiple air guide pipes are arranged vertically and are connected to the interior of the polymerization box.

[0014] A further technical improvement of the present invention is that: a cover plate is provided on one side of the polymerization box, and the cover plate is horizontally arranged, and the cover plate can cover the molding cavity along the length direction of the molding cavity.

[0015] A further technical improvement of the present invention is that: the linear drive component includes an electric slide rail, the electric slide rail is arranged along the length direction of the molding cavity, the feeding box is provided with a movable frame, and the movable frame is mounted on the electric slide rail.

[0016] A further technical improvement of the present invention is that a molding template is horizontally slidably installed inside the molding cavity, and a handle is provided at one end of the molding template.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This device uses an electric slide rail to drive the moving frame, feeding box and its components to move horizontally, so that the discharge roller moves along the length of the molding cavity and rotates, causing the plastic raw material in the discharge roller and its discharge groove to fall into the molding cavity. The transmission gear at one end of the discharge roller meshes with the rack, thereby driving the discharge roller to rotate evenly, thus ensuring that the plastic raw material in the discharge roller and its discharge groove can fall evenly into the molding cavity. When a geocell of a certain length is required, only the length of the plastic raw material falling into the molding cavity needs to be adjusted, which improves the applicability of the entire device. At the same time, the rack can position the discharge roller and its discharge groove, so that each time the plastic geocell is formed in the molding cavity, it can be in the same position in the molding cavity. The molding template in the molding cavity can correspond to the discharge groove on the discharge roller, thereby ensuring the accuracy of the geocell forming.

[0019] (2) The drive motor drives multiple rotating rods to rotate, thereby driving multiple conveying augers to rotate, causing the multiple conveying augers to move the molten plastic material in the feeding box to the discharge roller. At the same time, the molten plastic material in the feeding box slides down the conical groove to increase the aggregation of the plastic material. Then the molten plastic material slides along the polymerization box into the discharge box, causing the molten plastic material to adhere to the discharge groove of the discharge roller, so that the molten plastic material can be fully utilized.

[0020] (3) The discharge box and the discharge roller on it can be disassembled and installed on the polymerization box through the threaded fixing rod in the installation threaded hole, so as to facilitate the replacement of the discharge roller with different textured discharge grooves. The molding template can be moved horizontally by the handle, thereby driving the molding template to be disassembled and replaced in the molding cavity, thus ensuring that the molding template is compatible with the corresponding discharge groove, thereby improving the applicability of the whole device.

[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0028] Please see Figures 1-4 As shown, the present invention proposes an extrusion device for producing geocells, including a mounting platform 1, a forming cavity on the mounting platform 1, a feeding component on the mounting platform 1, and the feeding component being located above the forming cavity. The mounting platform 1 is also provided with a linear drive component for driving the feeding component to move horizontally.

[0029] The bottom of the feeding component is equipped with a discharge roller 2, and the discharge roller 2 is equipped with a discharge groove 3, which is arranged along the circumference of the discharge roller 2. One end of the discharge roller 2 is equipped with a transmission gear 4, and a rack 5 is provided on the mounting platform 1 along the length direction of the molding cavity. The transmission gear 4 and the rack 5 are meshed and connected for transmission. Molten plastic material is added into the feeding component, and the plastic material will move towards the discharge roller 2 through the feeding component, causing the molten plastic material to adhere to the discharge groove 3 of the discharge roller 2. Then, the feeding component is driven to move horizontally through a linear drive component, so that the discharge roller 2 moves along the length direction of the molding cavity. The discharge roller 2 rotates, causing the plastic raw material in the discharge roller 2 and its discharge trough 3 to fall into the molding cavity, thus forming the plastic geocell. At the same time, the transmission gear 4 at one end of the discharge roller 2 meshes with the rack 5, thereby driving the discharge roller 2 to rotate more evenly, ensuring that the plastic raw material in the discharge roller 2 and its discharge trough 3 can fall evenly into the molding cavity, thereby improving the molding effect of the plastic geocell. At the same time, the rack 5 can position the discharge roller 2 and its discharge trough 3, so that the plastic geocell can be in the same position in the molding cavity each time it is formed.

[0030] The feeding component includes a feeding box 6, on which a feeding pipe 7 is provided. The feeding pipe 7 is located on the top side of the feeding box 6. Multiple conveying components 8 are provided inside the feeding box 6. Each conveying component 8 includes a conveying auger 801 and a rotating rod 802. Multiple rotating rods 802 are rotatably connected to the feeding box 6. Multiple conveying augers 801 are respectively connected to one end of multiple rotating rods 802, and multiple conveying augers 801 are vertically arranged inside the feeding box 6. The feeding box 6 is provided with a drive motor 9 that drives the multiple rotating rods 802 to rotate. The drive motor 9 drives the multiple rotating rods 802 to rotate, thereby driving the multiple conveying augers 801 to rotate. This causes the multiple conveying augers 801 to move the molten plastic raw material in the feeding box 6 toward the discharge roller 2, thereby fully filling the discharge trough 3 with the molten plastic raw material and ensuring the molding effect of the plastic geocell.

[0031] The feeding box 6 is provided with a conical groove 10, and the bottom end of the conical groove 10 is provided with a polymerization box 11. The bottom end of the polymerization box 11 is connected to the discharge box 12, and the bottom end of the discharge box 12 is connected to the molding cavity. The discharge roller 2 is rotatably connected to the discharge box 12. The molten plastic material in the feeding box 6 slides downward along the conical groove 10 to increase the aggregation of the plastic material. Then the molten plastic material slides along the polymerization box 11 into the discharge box 12, and is discharged into the molding cavity through the rotating discharge roller 2 and the discharge groove 3, thereby ensuring the discharge effect of the plastic material.

[0032] The discharge box 12 and the polymerization box 11 are provided with connecting mounting threaded holes 19, and a threaded fixing rod 20 is provided in the mounting threaded holes 19; the discharge box 12 and the discharge roller 2 on it can be disassembled and installed on the polymerization box 11 through the threaded fixing rod 20 in the mounting threaded holes 19, so as to facilitate the replacement of the discharge roller 2 of the discharge trough 3 with different textures to form geocells with different textures, thereby improving the applicability of the whole device.

[0033] The feeding box 6 is equipped with multiple air guide pipes 13, which are arranged vertically and are connected to the interior of the polymerization box 11. When the molten plastic raw material is transferred in the feeding box 6, the multiple air guide pipes 13 guide air into the feeding box 6 and the polymerization box 11, thereby ensuring the normal air pressure in the feeding box 6 and the polymerization box 11, and thus ensuring the effective transfer of the molten plastic raw material.

[0034] A cover plate 14 is provided on one side of the polymerization box 11, and the cover plate 14 is set horizontally. The cover plate 14 can cover the molding cavity along the length direction of the molding cavity. When the feeding box 6 and the polymerization box 11 move horizontally, the cover plate 14 on the polymerization box 11 moves horizontally along the length direction of the molding cavity, thereby sealing the molding cavity and preventing the plastic geocell from being affected by external debris during molding, thus ensuring the molding effect of the plastic geocell.

[0035] The linear drive includes an electric slide rail 15, which is arranged along the length of the molding cavity. A movable frame 16 is provided on the feeding box 6 and is mounted on the electric slide rail 15. The electric slide rail 15 drives the movable frame 16, the feeding box 6 and its components to move horizontally, thereby driving the transmission gear 4 at one end of the discharge roller 2 to mesh with the rack 5, thereby driving the discharge roller 2 to rotate uniformly.

[0036] A molding template 17 is horizontally slidably installed inside the molding cavity, and a handle 18 is provided at one end of the molding template 17. The molding template 17 inside the molding cavity can correspond to the discharge groove 3 on the discharge roller 2, thereby ensuring the molding effect of the geocell. The molding template 17 is moved horizontally by the handle 18, thereby enabling the molding template 17 to be disassembled and replaced inside the molding cavity, thereby ensuring that the molding template 17 is compatible with the corresponding discharge roller 2 and discharge groove 3, thereby improving the applicability of the entire device.

[0037] In use, molten plastic material is added to the feeding component. The drive motor 9 drives multiple rotating rods 802 to rotate, thereby driving multiple conveying augers 801 to rotate. This causes the multiple conveying augers 801 to move the molten plastic material in the feeding box 6 towards the discharge roller 2. At the same time, the molten plastic material in the feeding box 6 slides downward along the conical groove 10 to increase the aggregation of the plastic material. Then, the molten plastic material slides along the polymerization box 11 into the discharge box 12, causing the molten plastic material to adhere to the discharge groove 3 of the discharge roller 2.

[0038] Then, the electric slide rail 15 drives the moving frame 16, the feeding box 6 and its components to move horizontally, so that the discharge roller 2 moves along the length of the molding cavity and rotates, causing the plastic raw material in the discharge roller 2 and its discharge groove 3 to fall into the molding cavity. The transmission gear 4 at one end of the discharge roller 2 meshes with the rack 5, thereby driving the discharge roller 2 to rotate evenly, thus ensuring that the plastic raw material in the discharge roller 2 and its discharge groove 3 can fall evenly into the molding cavity. At the same time, the rack 5 can position the discharge roller 2 and its discharge groove 3, so that each time the plastic geocell is formed in the molding cavity, it can be in the same position in the molding cavity. The molding template 17 in the molding cavity can correspond to the discharge groove 3 on the discharge roller 2, thereby ensuring the molding effect of the geocell.

[0039] The discharge box 12 and the discharge roller 2 thereon can be disassembled and installed on the polymerization box 11 through the threaded fixing rod 20 provided in the installation threaded hole 19, so as to facilitate the replacement of the discharge roller 2 of the discharge groove 3 with different textures. The molding template 17 is moved horizontally by the handle 18, so as to disassemble and replace the molding template 17 in the molding cavity, thereby ensuring that the molding template 17 is compatible with the corresponding discharge groove 3, thereby improving the applicability of the entire device.
