Description
Technical Field
[0001] The invention belongs to the technical field of film rolling machines, and in particular relates to a plastic film rolling machine with adjustable fastening force. Background Art
[0002] In the plastic film processing industry, film rolling machines are one of the key equipment in plastic film production lines. Their performance and efficiency are directly related to the quality and production cost of plastic film products. With the continuous expansion of the application field of plastic film, the requirements for film rolling machines are also increasing, especially in terms of the control of the fastening force of plastic film. Traditional film rolling machines mostly use a fixed fastening structure to achieve the winding and fixing of plastic film through mechanical compression or friction. However, this fixed fastening method has many limitations and it is difficult to meet the needs of modern plastic film production for precise control of fastening force.
[0003] However, although the existing technology has made certain progress in this regard, there are still significant deficiencies in the precise adjustment of the tightening force. On the one hand, due to the diversity of plastic film materials and different thicknesses, fixed fastening structures or simple electric and pneumatic adjustment methods are difficult to adapt to plastic films of different materials and thicknesses. This lack of adaptability can easily cause the plastic film to become loose or too tight after winding, thereby affecting the subsequent use and overall quality of the plastic film. The uniformity of winding and the control of the tightening force are particularly important. On the other hand, existing film winding machines often lack sufficient flexibility and precision when adjusting the tightening force, and cannot be fine-tuned according to actual needs, so staff need to improve them.

[0032] When in use, the servo motor 2 is used as a power source and can rotate forward and reverse, driving the driving wheel 4 to rotate through the driving rod 3, and then transmitting the power to the transmission wheel 6 through the transmission belt 5. The transmission wheel 6 is connected to the reducer 7. The function of the reducer 7 is to reduce the speed and increase the torque to ensure the stability during the film rolling process. The installation sleeve 8 is fixedly connected to the connecting pipe 10 through the support frame 9. A movable rod 11 is provided inside the connecting pipe 10. The top of the movable rod 11 is connected to the handle 12, and the bottom end is connected to the threaded rod 13. The threaded rod 13 is connected to the threaded plug rod 14 through a threaded connection. Sliding wheels 15 are provided around the threaded rod 14, and the sliding wheels 15 slide on the inner wall of the connecting tube 10, so that the threaded rod 14 can move up and down. By rotating the handle 12, the position of the threaded rod 14 can be adjusted, thereby controlling the tightening strength of the winding rod 16. The surface of the winding rod 16 is provided with an anti-slip rod 18 to ensure that the plastic film does not slip during the winding process, thereby achieving precise adjustment of the film winding force. The forward and reverse rotation functions of the servo motor 2 enable the film winding process to be adjusted as needed, ensuring the tightness and uniformity of the film winding, and improving the film winding efficiency and quality.
[0033] Example 2:
[0034] See also Figures 1 to 7 As shown, a winding rod 16 is inserted into the inner wall of the mounting sleeve 8, a limiting hole 17 is provided on the surface of the winding rod 16, and the inner wall of the limiting hole 17 is sleeved on the surface of the threaded insertion rod 14, and a plurality of anti-slip rods 18 are fixedly connected to the surface of the winding rod 16, a connecting sleeve 19 is sleeved on the surface of the winding rod 16, and a mounting rod 20 is fixedly connected to the bottom of the connecting sleeve 19, and a protective box 21 is overlapped on the top of the mounting platform 1, and fixing bolts are threadedly connected to both sides of the bottom of the protective box 21, and the surface of the fixing bolts is threadedly connected to the inner wall of the mounting platform 1.
[0035] When in use, the sleeve 8 is installed as the core supporting structure, and the winding rod 16 is inserted inside. A limiting hole 17 is provided on the surface of the winding rod 16 for cooperating with the threaded plug rod 14 to achieve the adjustment of the fixation and tightening force of the winding rod 16. A plurality of anti-slip rods 18 are fixedly connected to the surface of the winding rod 16. The anti-slip rods 18 can increase the friction between the plastic film and the winding rod 16 to prevent the plastic film from slipping or loosening during the winding process, thereby ensuring the stability and uniformity of the rolled film. A connecting sleeve 19 is also sleeved on the surface of the winding rod 16 to connect The bottom of the sleeve 19 is fixedly connected to the mounting rod 20, and the mounting rod 20 is used to support and fix the winding rod 16 to ensure that it remains stable during the film rolling process and avoids deviation or shaking due to uneven force. It not only achieves efficient winding of the plastic film, but also flexibly adjusts the fastening force of the winding rod 16 through the cooperation of the limiting hole 17 and the threaded insert rod 14 to ensure that the plastic film always maintains appropriate tension during the winding process to avoid being too loose or too tight. At the same time, the cooperation between the anti-slip rod 18 and the mounting rod 20 further enhances the stability and reliability of the film rolling.
[0036] Example 3:
[0037] See also Figures 1 to 7 As shown, heat dissipation fins 22 are fixedly connected to both sides of the protective box 21, an assembly box 23 is fixedly connected to the top of the protective box 21, a micro motor 24 is fixedly connected to the inner wall of the assembly box 23, a transmission rod 25 is installed at the output end of the micro motor 24, and a fan blade 26 is fixedly connected to the bottom end of the transmission rod 25.
[0038] When in use, the protective box 21 is used to protect the key components inside to prevent dust, foreign objects from entering or external impact from damaging the equipment. At the same time, the bottom of the protective box 21 is connected to the mounting platform 1 by fixing bolts to ensure its stability. The protective box 21 is fixedly connected to both sides of the heat dissipation fins 22. The heat dissipation fins 22 can effectively increase the heat dissipation area, help quickly dissipate the heat generated by the servo motor 2 and other components during operation, and prevent the equipment from being affected by overheating or damaged. The top of the protective box 21 is fixedly connected to the assembly box 23, and a micro motor 24 is installed inside the assembly box 23. The micro motor 24 drives the fan blades 26 to rotate through the transmission rod 25. The airflow generated by the fan blades 26 further enhances the heat dissipation effect of the equipment, ensuring that the equipment maintains a suitable operating temperature during long-term operation. It not only provides effective protection for the equipment, but also significantly improves the heat dissipation efficiency of the equipment through the dual heat dissipation mechanism of the heat dissipation fins 22 and the fan blades 26, avoiding equipment performance degradation or failure due to excessive temperature.
[0039] Example 4:
[0040] See also Figures 1 to 7 As shown, in industrial production, plastic films are widely used in various packaging, protection and covering scenarios, such as dustproof, moisture-proof and temporary protection in the fields of building materials, electronic products, mechanical equipment, etc. Since these application scenarios have high requirements on the winding tightness and uniformity of plastic films, traditional film rolling machines often find it difficult to accurately control the winding force, resulting in the plastic film becoming loose or too tight during the winding process, affecting the subsequent use effect. Therefore, a film rolling machine that can flexibly adjust the tightening force is needed to ensure that the plastic film maintains appropriate tension during the winding process to avoid quality problems caused by looseness or overtightening.
[0041] The factory installed a plastic film winding machine with adjustable tightening force at the end of the production line, ensuring that the mounting platform 1 is firmly fixed to the ground. The servo motor 2 is powered on, the drive rod 3 is connected to the drive wheel 4, and the drive belt 5 is connected to the drive wheel 6 and the reducer 7 in sequence, ensuring smooth power transmission. The winding rod 16 is inserted into the mounting sleeve 8 and engages with the threaded insert 14 through the stop hole 17, ensuring the correct initial position of the winding rod 16.
[0042] According to production requirements, the operator rotates the movable rod 11 through the handle 12, driving the threaded rod 13 to rotate, and then adjusts the position of the threaded rod 14. The threaded rod 14 is inserted into the limiting hole 17 of the winding rod 16.
[0043] Servo motor 2 has forward and reverse rotation capabilities, allowing it to flexibly adjust its rotation direction according to winding requirements. To increase winding density, servo motor 2 rotates forward, driving drive wheel 4 via drive rod 3. Drive wheel 4 transmits power to drive wheel 6 via transmission belt 5. Drive wheel 6 is connected to reducer 7, which transmits power to mounting sleeve 8, rotating winding rod 16 to tightly wind the plastic film. To reduce winding density or make reverse adjustments, servo motor 2 rotates in the reverse direction, partially loosening the winding tension and ensuring the plastic film is wound with the appropriate force, avoiding excessive tightness or looseness.
[0044] After the servo motor 2 is started, the winding force is flexibly adjusted through the forward and reverse functions, and the plastic film is evenly wound on the winding rod 16. The anti-slip rod 18 increases the friction between the plastic film and the winding rod 16 to prevent the plastic film from slipping or loosening during the winding process, ensuring the stability and uniformity of the rolled film.
[0045] When the plastic film is wound, the operator stops servo motor 2, removes the wound plastic film roll, and prepares for the next round of winding. With this equipment, the factory can complete the plastic film winding work efficiently and stably, ensuring product quality and improving production efficiency.
[0046] Working principle: The servo motor 2 is used as the power source. After starting, it drives the driving wheel 4 to rotate through the driving rod 3. The driving wheel 4 transmits power to the transmission wheel 6 through the transmission belt 5. The transmission wheel 6 is connected to the reducer 7. The reducer 7 transmits power to the mounting sleeve 8. The mounting sleeve 8 is fixedly connected to the connecting pipe 10 through the support frame 9, driving the winding rod 16 to rotate. The plastic film begins to wind on the winding rod 16. A limiting hole 17 is opened on the surface of the winding rod 16. The threaded insert 14 cooperates with the winding rod 16 through the limiting hole 17.
[0047] The operator rotates the movable rod 11 through the handle 12, and the threaded rod 13 at the bottom end of the movable rod 11 rotates accordingly, driving the threaded rod 14 to move up and down.
[0048] A plurality of anti-slip rods 18 are fixedly connected to the surface of the winding rod 16. The anti-slip rods 18 increase the friction between the plastic film and the winding rod 16 to prevent the plastic film from slipping or loosening during the winding process, thereby ensuring the stability and uniformity of the winding. The connecting sleeve 19 and the erection rod 20 further support and fix the winding rod 16 to ensure that it remains stable during the winding process and avoids deviation or shaking due to uneven force.
[0049] The protective box 21 is used to protect the key components inside and prevent dust, foreign objects from entering or external impact from damaging the equipment. The heat dissipation fins 22 and the fan blades 26 driven by the micro motor 24 work together to quickly dissipate the heat generated by the servo motor 2 and other components during operation, ensuring that the equipment maintains a suitable operating temperature during long-term operation and avoiding equipment performance degradation or failure due to overheating.
