Description

Technical Field

[0001] This utility model relates to the field of polymer material processing technology, and in particular to a high-efficiency plastic extrusion and drawing machine with tension adjustment. Background Technology

[0002] Plastic extrusion drawing, as an important polymer material processing technology, transforms plastic raw materials into high-strength fibers or filaments through melt extrusion and stretching processes, finding wide applications in packaging, construction, agriculture, and medical fields. This technology efficiently utilizes plastic materials, enhancing their mechanical properties and functionality. Furthermore, by adjusting process parameters, it allows for product diversification to meet the needs of different industries. In addition, the application of intelligent production equipment will further improve process precision and efficiency, driving the industry towards automation and refinement. In the future, with the integration of new materials and processes, plastic extrusion drawing technology is expected to expand its market reach in high-end fiber products and composite materials.

[0003] Plastic extrusion and filament drawing units integrate melting, extrusion, and stretching processes to transform plastics into high-strength, performance-controllable fibers or flat filaments, meeting industrial demands for lightweight and durable materials. Its core significance lies in three aspects: first, improving product mechanical properties and reducing waste through temperature control, screw optimization, and draw ratio adjustment; second, adapting to various plastics and modified materials, expanding applications in packaging, geotextiles, and filter materials; and third, promoting energy conservation and intelligent upgrades. Under environmental trends, this technology is compatible with recycled and biodegradable materials, promoting a circular economy, and has significant potential in the fields of high-end composite materials and precision filament drawing.

[0004] Some existing plastic extrusion filament units lack tension adjustment functions, which leads to uneven diameter, rough surface, or even filament breakage due to tension fluctuations during the stretching process. This defect is amplified, especially during high-speed production, when changes in the melt viscosity of the raw material or deviations in the traction speed can amplify it. Furthermore, in the subsequent winding stage, problems such as uneven tension and misalignment of layers can occur due to uncontrolled tension, which not only reduces the neatness of the rolls but may also cause loosening and detachment during transportation or use. Therefore, a high-efficiency plastic extrusion filament unit with tension adjustment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a high-efficiency plastic extrusion drawing unit with tension adjustment, which aims to improve the problem that when operators disassemble the drying cylinder or calendering roller, the unrestrained roll paper will produce irregular displacement due to mechanical vibration. This dynamic interference not only causes the shaft force application axis to deviate, but also causes scratches on the mating surface of the precision bearing seat.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency plastic extrusion and drawing machine unit with tension adjustment includes a base plate, a U-shaped plate fixedly connected to the top of the base plate, a stretching mechanism installed on the top of the U-shaped plate, a drawing mechanism installed on the top of the base plate, a water tank installed on the top of the base plate, a clamping plate installed on the top of the water tank, a rotating rod rotatably connected to the outside of the clamping plate, a rotating rod rotatably connected to the inside of the water tank, and a refrigeration unit installed inside the water tank. The stretching mechanism includes a housing, a control board mounted on the outside of the housing, a drive motor mounted on the top of the housing, a roller fixedly connected to the drive end of the drive motor, a lifting assembly mounted inside the housing, and a support plate fixedly connected to the outside of the lifting assembly. As a further description of the above technical solution: The lifting assembly includes a connecting plate, a slide rail fixedly connected to the outside of the connecting plate, a lifting motor mounted on the outside of the connecting plate, a rotating wheel fixedly connected to the drive end of the lifting motor, a belt coupled to the outside of the rotating wheel, a slider slidably connected to the outside of the slide rail, a fixing block fixedly connected to the outside of the belt, a limit block fixedly connected to the outside of the slide rail, and a fixing rod fixedly connected to the outside of the connecting plate. As a further description of the above technical solution: The wire drawing mechanism includes a support block and a discharge port. An electrical distribution box is installed on the outside of the support block. A discharge pipe is fixedly connected to the top of the support block. A feed port is fixedly connected to the top of the discharge pipe. A stirring rod is rotatably connected inside the feed port. A shaping component is installed inside the discharge pipe. A fixing component is installed on the outside of the discharge port. As a further description of the above technical solution: The shaping component includes a telescopic shell, a handle is fixedly connected to the outside of the telescopic shell, multiple partitions are fixedly connected to the inside of the telescopic shell, a shaping mesh is fixedly connected to the top of the partitions, a bolt is threadedly connected to the inside of the partitions, and a roller is rotatably connected to the outside of the telescopic shell. As a further description of the above technical solution: The fixing component includes a groove, a baffle is slidably connected inside the groove, and a bolt is threadedly connected inside the baffle.

As a further description of the above technical solution: The telescopic shell is slidably connected inside the discharge pipe, and the outside of the bolt is slidably connected inside the shaped mesh.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the operator controls the lifting motor to start through the control panel. After the lifting motor is started, the belt will start to rotate under the drive of the rotating wheel, thereby driving the pallet connected to the fixed block to move up and down on the slide rail. This causes the drive motor and the roller driven by the drive motor to move up and down outside the shell, thereby achieving a relatively uniform tension during the stretching process, reducing surface roughness or broken wires, and preventing problems such as difficulty in tightening or misalignment of layers due to uncontrolled tension during the subsequent winding process.

[0008] 2. In this utility model, the operator can remove the second bolt on the fixing component and pull the baffle out of the groove, so that the shaping component can slide inside the discharge pipe by pulling the handle to make the telescopic shell with rollers slide, thereby achieving quick disassembly. This enables the unit to adapt to multiple processing needs by disassembling the shaping mesh on the shaping module when facing different processing and shaping needs. At the same time, the detachable design greatly reduces downtime and maintenance costs in the event of equipment failure, and extends the service life of the components. Attached Figure Description

[0010] 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. Example

[0011] A high-efficiency plastic extrusion and drawing unit with tension adjustment, as described above. Figure 1 , Figure 2 and Figure 7 The system includes a base plate 1, which provides load and support for the connection of other components. A U-shaped plate 3 is fixedly connected to the top of the base plate 1, which also provides load and support for other components. A tensioning mechanism 2 is installed on the top of the U-shaped plate 3, which is used to adjust the tension. A wire drawing mechanism 4 is installed on the top of the base plate 1, which is used to process polymer materials. A water tank 5 is installed on the top of the base plate 1, which is used to store cold water to cool the plastic. A clamping plate 6 is installed on the top of the water tank 5, which restricts the movement of other components. A rotating rod 7 is rotatably connected to the outside of the clamping plate 6. A rotating rod 8 is rotatably connected to the inside of the water tank 5. The rotating rod 7 and the rotating rod 8 are used to perform simple stretching and guiding of the plastic. A chiller 9 is installed inside the water tank 5 to regulate the water temperature to meet the cooling requirements.

[0012] The stretching mechanism 2 includes a housing 21, which encloses the core component and provides physical protection. A control board 22 is mounted on the outside of the housing 21, which controls components that require motor operation. A drive motor 23 is mounted on the top of the housing 21, which drives other components to work. A roller 24 is fixedly connected to the drive end of the drive motor 23, which stretches the plastic in multiple stages to achieve tension adjustment. A lifting assembly 25 is installed inside the housing 21, which informs the roller 24 and the drive motor 23 of their height. A support plate 26 is fixedly connected to the outside of the lifting assembly 25, which provides load and support for the drive motor 23.

[0013] The lifting assembly 25 includes a connecting plate 251 for connecting other components. A slide rail 253 is fixedly connected to the outside of the connecting plate 251, allowing other components to slide in a specified direction. A lifting motor 252 is mounted on the outside of the connecting plate 251, driving the lifting assembly 25. A rotating wheel 254 is fixedly connected to the drive end of the lifting motor 252, rotating under the drive of the lifting motor 252. A belt 255 is externally coupled to the rotating wheel 254, rotating on the rotating wheel 254 and thus driving other components on the belt 255. The slide rail 253 is externally slidably connected to a slider 256, which slides on the slide rail 253. The belt 255 is externally fixedly connected to a fixing block 257, which is used to connect with other components so that the other components are driven by the belt 255. The slide rail 253 is externally fixedly connected to a limit block 258, which is used to limit the movement range of other components and prevent the pallet 26 from moving beyond the length of the slide rail 253, thus causing the pallet 26 to detach from the slide rail 253. The connecting plate 251 is externally fixedly connected to a fixing rod 259, which is used to connect a rotating wheel 254 to the other end of the slide rail 253.

[0014] The bottom of the slide rail 253 is fixedly connected to the inside of the housing 21, the outside of the support plate 26 is fixedly connected to the outside of the slider 256, the outside of the support plate 26 is fixedly connected to the outside of the fixing block 257, the inside of the rotating wheel 254 is rotatably connected to the outside of the fixing rod 259, and the bottom of the drive motor 23 is fixedly connected to the top of the support plate 26.

[0015] Specifically, the lifting motor 252 is turned on by the control board 22. After the lifting motor 252 is turned on, the belt 255 will start to rotate under the drive of the rotating wheel 254, thereby driving the pallet 26 connected to the fixed block 257 to move up and down on the slide rail 253, so that the drive motor 23 and the roller 24 driven by the drive motor 23 will move up and down outside the housing 21.

[0016] Refer to the figures and diagrams Figures 4 to 6 The drawing mechanism 4 includes a support block 41 and a discharge port. The support block 41 is used to raise other components and provide load and support for them. A power distribution box 42 is installed on the outside of the support block 41. The power distribution box 42 is used to control the power switch of the drawing mechanism 4. A discharge pipe 45 is fixedly connected to the top of the support block 41. The discharge pipe 45 is used as a channel for discharging the processed plastic. A feed port 43 is fixedly connected to the top of the discharge pipe 45. The feed port 43 is used to add the mixed material into the drawing mechanism 4 for processing. A stirring rod 44 is rotatably connected inside the outlet 43. The stirring rod 44 is used to stir the added materials to make the materials more uniform and the quality of the processed products more stable. A shaping component 46 is installed inside the discharge pipe 45. The shaping component 46 is used to shape the mixed materials after heat processing, so that the wire drawing mechanism 4 can produce products according to the processing requirements. A fixing component 47 is installed outside the discharge port. The fixing component 47 is used to stabilize the position of the shaping component 46 and prevent the shaping component 46 from shifting, which would cause unstable product quality.

[0017] The shaping component 46 includes a telescopic shell 461, which serves as a carrier for other components of the shaping component 46, facilitating connection between them. A handle 462 is fixedly connected to the outside of the telescopic shell 461, allowing for disassembly of the shaping component 46 by pulling it out. Multiple partitions 463 are fixedly connected inside the telescopic shell 461, used for dragging and dropping other components. A shaping mesh 464 is fixedly connected to the top of each partition 463 for shaping the material. Bolts 465 are threadedly connected inside each partition 463, securing the shaping mesh. Fixed on the partition plate 463, the telescopic shell 461 is rotatably connected to the outside of the roller 466. The roller is used to make it easier to disassemble and install the telescopic shell 461 in the discharge pipe 45. The fixing component 47 includes a groove 471, which is used to provide load for other inserted parts. A baffle 472 is slidably connected inside the groove 471. The baffle 472 is used to restrict the movement of the shaping component 46. A bolt 473 is threaded inside the baffle 472. The bolt 473 is used to fix the baffle 472 to the discharge pipe 45, thereby restricting the movement of the shaping component 46.

[0018] The bottom of the distribution box 42 is fixedly connected to the top of the base plate 1. The outside of the groove 471 is fixedly connected to the outside of the discharge pipe 45. The outside of the bolt 473 is threadedly connected to the inside of the discharge pipe 45. The telescopic shell 461 is slidably connected to the inside of the discharge pipe 45 and slidably connected to the inside of the plastic mesh 464 outside the bolt 465.

[0019] Specifically, by removing bolt 473 on the fixing component 47, the baffle 472 can be pulled out of the groove 471, allowing the shaping component 46 to slide inside the discharge pipe 45 by pulling the handle 462, thereby achieving quick disassembly.

[0020] The implementation principle of this application embodiment is as follows: the operator adds raw pulp at the feed inlet 43, processes it in the drawing mechanism 4, and completes the shaping by passing through the shaping mesh 464 in the shaping component 46 in the discharge pipe 45, so that the product meets the processing requirements. Then the product is produced from the discharge pipe 45, first passes through the water tank 5, and is cooled by cold water, and then passes through the stretching mechanism 2 to complete the tension adjustment.

[0021] The operator controls the lifting motor 252 via the control panel 22. After the lifting motor 252 is turned on, the belt 255 will start to rotate under the drive of the rotating wheel 254, thereby driving the pallet 26 connected to the fixed block 257 to move up and down on the slide rail 253. This causes the drive motor 23 and the roller 24 driven by the drive motor 23 to move up and down outside the housing 21. This achieves stable tension during the stretching process, resulting in relatively uniform product tension, reducing surface roughness or broken wires, and preventing problems such as difficulty in tightening or misalignment of layers due to uncontrolled tension during subsequent winding.

[0022] During equipment maintenance, operators can remove bolts 473 on the fixing component 47 and pull the baffle 472 out of the groove 471. This allows the shaping component 46 to slide inside the discharge pipe 45 by pulling the handle 462, which in turn allows the telescopic shell 461 with rollers 466 to slide. This enables quick disassembly, allowing the unit to adapt to different processing and shaping needs by disassembling the shaping mesh 464 on the shaping module. At the same time, the detachable design greatly reduces downtime and maintenance costs in the event of equipment failure, and extends the service life of components.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
