Description

Technical Field

[0001] This utility model relates to the field of mulch film production technology, and in particular to a traction device for increasing the speed of mulch film production. Background Technology

[0002] Mulch film production is the process of processing plastic raw materials into films with a certain thickness, width and performance through processes such as heating, extrusion, blow molding or calendering, for use in agricultural mulching. The traction device provides power for the movement of the mulch film on the production line, enabling it to pass through each production process in sequence. The mulch film extruded from the extruder smoothly passes through cooling, shaping, printing and other stages under the action of the traction device, and finally completes the production, ensuring the continuity of the production process.

[0003] Current mulch film production traction devices typically lack tension adjustment mechanisms during use, resulting in the inability to adjust the tension of the mulch film in a timely manner. When the traction force on the mulch film is uneven or excessive, local overstretching can easily occur, leading to rupture or cracks in the mulch film. This not only wastes materials but also requires downtime to replace the mulch film, severely impacting production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the tension force in the conveying of plastic film cannot be adjusted in the existing technology, which causes uneven traction force and affects production efficiency. To this end, we propose a traction device to increase the production speed of plastic film.

[0005] To achieve the above objectives, this application adopts the following technical solution: a traction device for increasing the production speed of plastic film, comprising a first fixed plate, a second fixed plate installed at one end of the first fixed plate, two traction rollers installed inside the first and second fixed plates, a rotating motor installed at the other end of the first fixed plate, an adjustment groove formed on the surface of the first fixed plate, a fixed rod fixedly connected inside the adjustment groove, an adjustment block slidably connected inside the adjustment groove and to the surface of the fixed rod, an adjustment roller installed on the opposite side of the adjustment block, traction grooves formed at both the top and bottom of the adjustment block, a traction block slidably connected inside the traction groove, a deflector plate fixedly connected to the opposite side of the traction block, a limit rod fixedly connected to one side of the deflector plate, a locking plate rotatably connected to one end of the adjustment block, limit grooves formed inside both the adjustment block and the adjustment groove, a limit rod slidably connected inside the limit groove, and a locking post fixedly connected to the other end of the deflector plate.

[0006] Preferably, the front and rear ends of the traction groove are provided with first sliding grooves, and the front and rear ends of the traction block are fixedly connected with first sliders, and the interior of the first sliding groove is slidably connected to the first sliders.

[0007] Preferably, a spring is sleeved on the surface of the limiting rod, and the two sides of the spring are fixedly connected to the inside of the toggle plate and the adjusting block, respectively.

[0008] Preferably, a second sliding groove is provided on both sides of the inside of the adjustment groove, and a second slider is fixedly connected to both sides of the adjustment block, and the inside of the second sliding groove is slidably connected to the second slider.

[0009] Preferably, an energy storage spring is sleeved on the surface of the fixing rod, the top end of the energy storage spring is fixedly connected to the inside of the adjusting groove, and the bottom end of the energy storage spring is fixedly connected to the top end of the adjusting block.

[0010] Preferably, the surface of the traction roller is provided with friction grooves, and the number of friction grooves is multiple and evenly distributed on the surface of the traction roller.

[0011] Preferably, the adjusting roller is made of stainless steel.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, when workers need to adjust the tension of the mulch film during transport, the locking plate is engaged with the locking post to release the fixed actuating plate. The actuating plate is then moved to pull the limiting rod out of the limiting groove, releasing the fixed adjusting block. The adjusting block is then moved to drive the adjusting roller against the mulch film, adjusting it to the appropriate tension. The actuating plate is then moved to re-insert the limiting rod into the limiting groove, and the locking plate is engaged with the locking post, achieving synchronous fixing of the adjusting block and the adjusting roller. By adjusting the tension during mulch film production, the tension can be adjusted according to changes in production speed, ensuring the mulch film maintains appropriate tension. This prevents the mulch film from becoming loose or misaligned due to insufficient tension, or from breaking due to excessive tension, thus ensuring the stability of the mulch film during high-speed operation, reducing production interruptions and defect rates, and improving production efficiency.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a traction device for increasing the production speed of plastic film, including a first fixed plate 1, a second fixed plate 2 installed at one end of the first fixed plate 1, two traction rollers 3 installed inside the first fixed plate 1 and the second fixed plate 2, a rotating motor 4 installed at the other end of the first fixed plate 1, an adjustment groove 5 opened on the surface of the first fixed plate 1, a fixed rod 6 fixedly connected inside the adjustment groove 5, an adjustment block 7 slidably connected inside the adjustment groove 5 and the surface of the fixed rod 6, an adjustment roller 8 installed on the opposite side of the adjustment block 7, traction grooves 9 opened at both the top and bottom ends inside the adjustment block 7, a traction block 10 slidably connected inside the traction groove 9, a toggle plate 11 fixedly connected to the opposite side of the traction block 10, a limit rod 12 fixedly connected to one side of the toggle plate 11, a snap-fit ​​plate 13 rotatably connected to one end of the adjustment block 7, and limit grooves 14 opened inside both the adjustment block 7 and the adjustment groove 5, the limit grooves 14 slidingly connected to the limit rod 12. The other end of the actuating plate 11 is fixedly connected to a locking post 18. When the operator needs to adjust the tension of the mulch film during transport, the locking plate 13 is engaged with the locking post 18 to release the actuating plate 11. Then, the actuating plate 11 is moved to pull the limiting rod 12 out of the limiting groove 14, releasing the adjusting block 7. At this time, the adjusting block 7 is moved to drive the adjusting roller 8 to abut against the mulch film, adjusting the mulch film to the appropriate tension. Then, the actuating plate 11 is moved again to insert the limiting rod 12 back into the limiting groove 14, and the locking plate 13 is then engaged with the locking post 18 to achieve synchronous fixation of the adjusting block 7 and the adjusting roller 8. By adjusting the tension of the mulch film during production, the tension of the mulch film can be adjusted according to the changes in production speed, so that the mulch film always maintains a suitable tension, avoiding slackness and deviation due to insufficient tension, or breakage due to excessive tension, thereby ensuring the stability of the mulch film under high-speed operation, reducing production interruptions and defect rates, and improving production efficiency.

[0022] Reference Figure 5 As shown in this embodiment: the front and rear ends of the traction groove 9 are provided with first sliding grooves 15, and the front and rear ends of the traction block 10 are fixedly connected with first sliders 16. The interior of the first sliding groove 15 is slidably connected to the first sliders 16. Through the setting of the first sliding groove 15 and the first sliders 16, the toggle plate 11 can form a stable guiding effect when it moves inside the adjusting block 7, so that the limiting rod 12 can be stably inserted into the limiting groove 14 without deviation, effectively ensuring the effective fixation of the adjusting roller 8 after adjustment.

[0023] Reference Figure 5 As shown in this embodiment: a spring spring 17 is sleeved on the surface of the limiting rod 12. The two sides of the spring spring 17 are fixedly connected to the inside of the actuating plate 11 and the adjusting block 7, respectively. By setting the spring spring 17, when it is necessary to adjust the position of the adjusting roller 8, the actuating plate 11 is released. At this time, the elastic force stored in the spring spring 17 is released, which drives the limiting rod 12 to pop out from the inside of the limiting groove 14, so that the adjusting block 7 is released, thereby achieving convenient adjustment of the adjusting roller 8 and improving operating efficiency.

[0024] Reference Figure 2 and Figure 3 As shown in this embodiment: a second sliding groove 19 is provided on both sides of the inside of the adjusting groove 5, and a second slider 20 is fixedly connected to both sides of the adjusting block 7. The inside of the second sliding groove 19 is slidably connected to the second slider 20. Through the setting of the second sliding groove 19 and the second slider 20, the adjusting block 7 can form a stable limiting effect when sliding inside the adjusting groove 5, thereby making the adjusting roller 8 more stable when adjusting up and down, less prone to shaking and deviation, and improving the stability and adjustment efficiency during the adjustment process.

[0025] Reference Figure 2 As shown in this embodiment: an energy storage spring 21 is sleeved on the surface of the fixing rod 6. The top end of the energy storage spring 21 is fixedly connected to the inside of the adjusting groove 5, and the bottom end of the energy storage spring 21 is fixedly connected to the top end of the adjusting block 7. With the setting of the energy storage spring 21, when the ground film is conveyed, the adjusting block 7 is released. At this time, the elastic force or tension stored in the energy storage spring 21 is released, which drives the adjusting block 7 to move to the initial position, thereby achieving convenient reset of the adjusting roller 8 after use, which is convenient for the next use.

[0026] Reference Figure 1 As shown in this embodiment: the surface of the traction roller 3 is provided with friction grooves 22. There are multiple friction grooves 22 and they are evenly distributed on the surface of the traction roller 3. By setting the friction grooves 22, the traction roller 3 and the mulch film can have greater friction, thereby making the mulch film less prone to deviation and parallel sliding during the transportation process, and improving the transportation efficiency of the mulch film.

[0027] Reference Figure 3 As shown in this embodiment: the adjusting roller 8 is made of stainless steel. By using the adjusting roller 8 made of stainless steel, the adjusting roller 8 has higher strength and corrosion resistance when adjusting the tension of the mulch film, ensuring that it is not easily deformed or damaged during long-term use. At the same time, the stainless steel material also has good wear resistance, which can reduce frictional wear between it and the mulch film and extend its service life.

[0028] Working principle: When the operator needs to adjust the tension of the plastic film during delivery, the locking plate 13 is engaged with the locking post 18 to release the fixed actuating plate 11. Then, the actuating plate 11 is moved to pull the limiting rod 12 out of the limiting groove 14, releasing the fixed adjusting block 7. At this point, the adjusting block 7 is moved, causing the adjusting roller 8 to abut against the plastic film, adjusting the film to the appropriate tension. The actuating plate 11 is then moved again to insert the limiting rod 12 back into the limiting groove 14, and the locking plate 13 is then engaged with the locking post 18, achieving synchronous fixing of the adjusting block 7 and the adjusting roller 8. This allows for adjustment of the tension during plastic film production, which can be adjusted according to changes in production speed. The tension of the mulch film ensures it maintains appropriate tension, preventing it from becoming loose or misaligned due to insufficient tension, or breaking due to excessive tension. This guarantees the stability of the mulch film during high-speed operation, reduces production interruptions and defect rates, and improves production efficiency. The first groove 15 and the first slider 16 provide a stable guide for the actuating plate 11 as it moves within the adjusting block 7, allowing the limiting rod 12 to be stably inserted into the limiting groove 14 without deviation. This effectively ensures the effective fixation of the adjusting roller 8 after adjustment. The spring spring 17 allows the actuating plate to be adjusted when the position of the adjusting roller 8 needs to be changed. 11. When the fixing is released, the elastic force stored in the elastic spring 17 is released, causing the limiting rod 12 to pop out from inside the limiting groove 14, thus releasing the fixing of the adjusting block 7. This allows for convenient adjustment of the adjusting roller 8, improving operational efficiency. The second slide groove 19 and the second slider 20 ensure a stable limiting effect when the adjusting block 7 slides inside the adjusting groove 5, making the adjusting roller 8 more stable during up-and-down adjustment, less prone to wobbling and deviation, improving stability and efficiency during adjustment. With the energy storage spring 21, after the ground film is conveyed, the fixing of the adjusting block 7 is released, and the elastic force or tension stored in the energy storage spring 21 is released. The release mechanism moves the adjusting block 7 to its initial position, allowing the adjusting roller 8 to be easily reset after use, facilitating future use. The friction groove 22 increases the friction between the traction roller 3 and the mulch film, preventing the mulch film from shifting or sliding during transport and improving transport efficiency. The stainless steel adjusting roller 8 provides higher strength and corrosion resistance when adjusting the tension of the mulch film, ensuring it is less prone to deformation or damage during long-term use. Furthermore, the stainless steel material has excellent wear resistance, reducing frictional wear and extending service life.
