Technical Field
[0001] The utility model relates to the technical field of film production, in particular to a film guiding device for controlling the transmission direction. Background Art
[0002] Film, as one of the indispensable materials in modern industry and daily life, has a wide range of applications, from food packaging, electronic product protection, medical supplies to building materials. The diversity of film is not only reflected in its material - from plastic films such as polyethylene and polypropylene, to special films based on adhesives, to rubber films and various composite films, each material gives the film unique physical, chemical properties and usage characteristics. In the film production process, winding is a crucial link, which is responsible for winding the continuously produced film according to a certain length or weight for easy storage and transportation. and subsequent processing, however, to ensure the efficiency and high quality of the winding process, the smooth transmission of the film is a prerequisite, among which the guide roller plays a key role in film transmission, but the traditional guide roller system often seems powerless when facing complex and changeable film materials, especially in the winding process of the film. When the film material is soft and easy to deform, or the production speed is fast, wrinkles are prone to appear on the surface of the film, which not only affects the aesthetics of the film, but may also damage its physical properties, thereby affecting the subsequent winding effect and product quality. In addition, the film will also shift in position during the winding process, resulting in problems such as uneven winding and film damage. Utility Model Content
[0003] The main purpose of the utility model is to provide a film guiding device for controlling the transmission direction, which can effectively solve the problems in the background technology.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] The film guide device for controlling the transmission direction comprises a workbench, the upper right part of the workbench is fixedly connected to a connecting frame, the middle part of the inner front wall and the middle part of the inner rear wall of the connecting frame are jointly movably connected with a film roller, the rear right part of the workbench is fixedly connected to an adjusting tensioning force device, the adjusting tensioning force device is located on the left side of the connecting frame, the upper left part of the workbench is fixedly connected to a frame, the front upper part of the frame is fixedly connected to a control keyboard, the right part of the inner front wall and the right part of the inner rear wall of the frame are both provided with a cross slot with a through upper end, and a film flattening structure is jointly slidably connected in the two cross slots, and the front upper part of the frame is fixedly connected to a main roller, and the rear of the main roller is located in the frame.
[0006] The film flattening structure includes a lower pressure roller, the front end and rear end of the lower pressure roller are fixedly connected to the lower part of the inner front wall and the lower part of the inner rear wall of the frame respectively, a connecting shaft is provided directly above the lower pressure roller, the outer surface of the connecting shaft is movably connected with the upper pressure roller, and the front end and rear end of the connecting shaft are fixedly connected with a cross block.
[0007] Preferably, the lower pressure roller is located at the lower right of the main roller, and the connecting shaft is movably connected to the frame through two cross clamping blocks and two cross clamping slots.
[0008] By adopting the above technical solution: the lower pressure roller and the upper pressure roller can cooperate to flatten the film passing through them, the connecting shaft provides support and rotation axis for the upper pressure roller, so that the upper pressure roller can rotate stably, and the connecting shaft is movably connected to the cross slot of the frame through the cross clamp block. This connection method not only ensures the stability of the position of the upper pressure roller, but also facilitates flexible adjustment of its position according to different thicknesses of films or flattening requirements to achieve the best flattening effect.
[0009] Preferably, the tension adjustment device includes a frame, which is fixedly connected to the left rear end of the workbench, and limiting grooves are provided on the rear end of the inner left wall and the rear end of the inner right wall of the frame. The upper end of the frame is fixedly connected to a servo motor, and the output end of the servo motor passes through the middle of the upper end of the frame and is fixedly connected to a screw rod. The lower end of the screw rod is movably connected to the frame through a bearing, and the outer surface of the frame is movably connected to an anti-correction component through threads.
[0010] By adopting the above technical solution: the limiting slide can limit the movement of the anti-correction component, ensuring that the anti-correction component can only move smoothly along a specific direction. The anti-correction component directly acts on the film, and changes the tension of the film by its up and down movement, which can adjust the tension and prevent the film from correcting.
[0011] Preferably, the anti-correction component includes a base fixing frame, a screw hole is opened at the upper rear end of the base fixing frame, an enlarged friction roller is movably connected between the upper inner front wall and the upper inner rear wall of the base fixing frame, and a correction block is movably connected between the outer front and outer rear surfaces of the enlarged friction roller.
[0012] By adopting the above technical solution: the base fixing frame provides support and installation basis for the entire anti-correction component, the main function of the enlarged friction roller is to increase the friction between it and the film. When the film passes by, the enlarged friction roller can better control the movement of the film and prevent the film from deviating during the transmission process. The two correction blocks are interlaced and movably connected at the front and rear of the outer surface of the enlarged friction roller. They can assist the enlarged friction roller to correct the film. When the film has a tendency to deviate, the correction block can limit the deviation direction of the film and help the film maintain the correct position, thereby playing a role in preventing deviation.
[0013] Preferably, the base fixing frame is movably connected to the screw rod through a screw hole, and the left rear end and the right rear end of the base fixing frame are respectively located in two limiting sliding grooves and are slidably connected.
[0014] By adopting the above technical solution: the screw hole cooperates with the screw rod thread, so that when the screw rod rotates, it can drive the base fixing frame to move up and down along the screw rod, and the position of the base fixing frame can be adjusted, thereby changing the height position of the anti-correction component to achieve the purpose of adjusting the tension. The left rear end and the right rear end of the base fixing frame slide in two limiting slide grooves respectively, limiting the movement of the base fixing frame to only along the vertical frame, preventing it from deflecting or rotating, and ensuring the stability and accuracy of the movement of the base fixing frame.
[0015] Preferably, the two deviation-correcting blocks are distributed in a front-to-back mirror image manner, and the friction-enhancing roller is located between the lower pressure roller and the film roller.
[0016] By adopting the above technical solution: the two correction blocks are distributed in a front-to-back mirror image manner. This distribution method can correct and limit the film passing through the enlarged friction roller from the front and back directions, ensuring the stability of the front and back position of the film during transmission, reducing the deviation of the film in the transmission direction, and the enlarged friction roller is located between the lower pressure roller and the film roller. This position enables the enlarged friction roller to play a tensioning and limiting role in the process of transmitting the film from the film roller to the lower pressure roller.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. In the utility model, through the cooperation of the upper pressure roller and the lower pressure roller, uniform pressure can be applied to the passing film, effectively eliminating wrinkles on the surface of the film, making its surface smooth, and improving the aesthetics and physical properties. In addition, the connecting shaft is movably connected to the frame through a cross block and a cross slot, and the position of the upper pressure roller can be flexibly adjusted according to the hardness and production speed of the film material, thereby changing the pressure on the film, ensuring that a good flattening effect can be achieved under different conditions, and can also adapt to the production of films with different specifications and requirements.
[0019] 2. In the present invention, a servo motor drives the screw rod to rotate, causing the base bracket to move up and down along the screw rod, thereby precisely adjusting and increasing the pressure of the friction roller on the film, thereby achieving precise control of the film tension. Appropriate tension can reduce the film's slack and shaking during transmission, reducing the possibility of positional deviation. The mirror-image distribution of the front and back correction blocks can limit the film's deviation from the front and back directions. When the film tends to deviate, the correction blocks can promptly block and correct its position, ensuring that the film is transported along the correct path. This effectively solves the problem of film positional deviation, allows the film to be more neatly wound during the winding process, and prevents film damage, thereby significantly improving the winding quality and yield rate.

[0029] See also Figure 1-5 , the utility model provides a technical solution:
[0030] A film guiding device for controlling the transmission direction includes a workbench 1, a connecting frame 2 is fixedly connected to the upper right end of the workbench 1, and a film roller 3 is movably connected to the middle of the inner front wall and the middle of the inner rear wall of the connecting frame 2. A tensioning force adjustment device 4 is fixedly connected to the right rear end of the workbench 1, and the tensioning force adjustment device 4 is located on the left side of the connecting frame 2. The upper left end of the workbench 1 is fixedly connected to a frame 5, and a control keyboard 6 is fixedly connected to the upper front end of the frame 5. A cross slot 7 with a through upper end is opened on the right inner front wall and the right inner rear wall of the frame 5, and a film flattening structure 9 is slidably connected in the two cross slots 7. A main roller 8 is fixedly connected to the upper front end of the frame 5, and the rear of the main roller 8 is located inside the frame 5.
[0031] In this embodiment, the film flattening structure 9 includes a lower pressure roller 91, the front end and the rear end of the lower pressure roller 91 are fixedly connected to the lower part of the inner front wall and the lower part of the inner rear wall of the frame 5 respectively, and a connecting shaft 92 is provided directly above the lower pressure roller 91. The outer surface of the connecting shaft 92 is movably connected with an upper pressure roller 93, and the front end and the rear end of the connecting shaft 92 are fixedly connected with a cross block 94. The lower pressure roller 91 is located at the lower right of the main roller 8, and the connecting shaft 92 is movably connected to the frame 5 through two cross blocks 94 and two cross slots 7 respectively.
[0032] Through the above scheme: during the transmission process, the film passes between the lower pressure roller 91 and the upper pressure roller 93. Since the lower pressure roller 91 is fixed on the frame 5 and its position remains unchanged, and the upper pressure roller 93 is movably connected to the cross slot 7 on the frame 5 through the cross block 94 at the front and rear ends of the connecting shaft 92, the position of the upper pressure roller 93 can be adjusted as needed. When the film passes through, the lower pressure roller 91 provides support and downward pressure, and the upper pressure roller 93 applies pressure. Under the joint action of the two, the passing film can be squeezed, thereby achieving a flattening effect. By adjusting the position of the upper pressure roller 93, the pressure on the film can be controlled to meet the flattening requirements of films of different thicknesses or materials.
[0033] In this embodiment, the tension adjustment device 4 includes a frame 41, which is fixedly connected to the left rear end of the workbench 1. The rear inner left wall and the rear inner right wall of the frame 41 are both provided with limiting slide grooves 42. The upper end of the frame 41 is fixedly connected to a servo motor 43. The output end of the servo motor 43 passes through the middle of the upper end of the frame 41 and is fixedly connected to a screw rod 44. The lower end of the screw rod 44 is movably connected to the frame 41 through a bearing. The outer surface of the frame 41 is movably connected to an anti-correction component 45 through a thread. The anti-correction component 45 includes a base fixing frame 451. The upper rear end of the base fixing frame 451 There is a through screw hole 452, and an enlarged friction roller 453 is inserted and movably connected between the upper part of the inner front wall and the upper part of the inner rear wall of the base fixing frame 451. The outer front and outer rear surfaces of the enlarged friction roller 453 are both inserted and movably connected with a correction block 454. The base fixing frame 451 is threadably connected to the screw rod 44 through the screw hole 452. The left rear end and the right rear end of the base fixing frame 451 are respectively located in the two limiting slide grooves 42 for sliding connection. The two correction blocks 454 are distributed in a front-to-back mirror image. The enlarged friction roller 453 is located between the lower pressure roller 91 and the film roller 3.
[0034] Through the above scheme: when working, the film is unfolded from the film roller 3, passes above the increased friction roller 453 located on the left side of the lower pressure roller 91 and the film roller 3, and the servo motor 43 is started to work. The output end of the servo motor 43 drives the screw rod 44 to rotate. Since the base fixing frame 451 is threadedly connected to the screw rod 44 through the screw hole 452, and the left rear end and the right rear end of the base fixing frame 451 slide in the two limiting slide grooves 42 respectively, the base fixing frame 451 is limited to move only along the vertical direction of the frame 41. When the screw rod 44 rotates, the base fixing frame 451 will move up and down along the screw rod 44. Through this up and down movement, the contact pressure between the increased friction roller 453 and the film can be changed, thereby adjusting the tension of the film. At the same time, the front and rear mirror-distributed correction blocks 454 can limit and correct the film from the front and rear directions during the film transmission process to prevent the film from deviating.
[0035] It should be noted that the present invention is a film guiding device for controlling the transmission direction. During use, the film is wound around the film roller 3, and then one end of the film is unfolded from the film roller 3. The film is located on the upper side of the increased friction roller 453 and then passes between the lower pressure roller 91 and the upper pressure roller 93 and is wrapped and fixed to the outer surface of the main roller 8. By starting the servo motor 43, the servo motor 43 drives the screw rod 44 to rotate. Since the base fixing frame 451 is threadedly connected to the screw rod 44 through the screw hole 452, and the left rear end and the right rear end of the base fixing frame 451 slide in the two limiting slide grooves 42 respectively, when the screw rod 44 rotates, the base fixing frame 451 will move up and down along the screw rod 44, and this movement will change the contact between the increased friction roller 453 and the film. The contact pressure is used to adjust the tension of the film. At the same time, the front and rear mirror-image distribution of the correction blocks 454 can limit and correct the film to prevent it from deviating. After the tension is adjusted and the correction is corrected, the film continues to be transmitted and will pass between the lower pressure roller 91 and the upper pressure roller 93. Because the lower pressure roller 91 is fixed on the frame 5, the upper pressure roller 93 is movably connected to the cross slot 7 on the frame 5 through the cross clamping blocks 94 at the front and rear ends of the connecting shaft 92, and the position can be adjusted according to the thickness and flattening requirements of the film, so that the upper pressure roller 93 and the lower pressure roller 91 can jointly squeeze and flatten the film, and the flattened film is transmitted to the main roller 8. Therefore, the entire transmission and processing process can be controlled and adjusted through the control keyboard 6, and finally the film can be guided, tensioned, corrected and flattened.
[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
