Description

Technical Field

[0001] This utility model relates to the field of protective film processing technology, specifically a positioning and die-cutting device for protective film processing. Background Technology

[0002] Protective film processing refers to the production, fabrication, customization, and further processing of protective films to meet the needs of different industries and users. Processing technology: Protective films require multiple processing techniques from production to material processing. Common processes include blown film extrusion, where plastic is melted and plasticized in an extruder, extruded into a film tube through a ring die, and then inflated and cooled by compressed air to form a thin film; casting, which uses a multi-layer co-extrusion process, where molten resin is extruded through a T-die and then cooled by a quenching roller to obtain a film; and biaxial stretching.

[0003] Patent Publication No.: CN220364117U. This utility model relates to the field of protective film processing technology and discloses a film cutting device for protective film processing. It includes a die-cutting table, two feeding rollers for conveying the protective film, a die-cutting equipment body, and a die-cutting device for die-cutting the protective film. Support legs are fixed at the four corners of the bottom of the die-cutting table. The device also includes a fixed box on the left side of the bottom of the die-cutting table, with a drive structure inside; and an L-shaped mounting bracket on the left side of the die-cutting table. This utility model has a cleaning function, allowing the die-cutting device to automatically clean the dust on the surface of the feeding rollers, effectively improving the cleaning effect. Furthermore, the cleaning structure on top of the device has a storage function, allowing it to be flipped and stored after use, thus preventing the cleaning structure from affecting the feeding of the protective film and providing convenience for the workers.

[0004] Current die-cutting equipment can only clean the feeding rollers, but cannot adjust the spacing between them. This means that for protective films of different thicknesses, the spacing between the feeding rollers needs to be manually adjusted, which is not quick and reduces the working efficiency of the die-cutting equipment. Utility Model Content

[0005] The purpose of this invention is to provide a positioning die-cutting device for protective film processing. This solves the problem that current film cutting devices can only clean the feeding rollers but cannot adjust the spacing between them. As a result, when using protective films of different thicknesses, the spacing between the feeding rollers needs to be manually adjusted, which cannot be done quickly and reduces the working efficiency of the die-cutting equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning die-cutting device for protective film processing, comprising a positioning die-cutting device body, a die-cutting component fixedly installed on the right side of the top of the positioning die-cutting device body, a fixed plate fixedly connected to the left side of the top of the positioning die-cutting device body, a first transmission roller rotatably connected to the inner side of the fixed plate, a movable frame slidably connected to the left side of the bottom of the positioning die-cutting device body, a second transmission roller rotatably connected to the inside of the movable frame, a servo motor fixedly connected to the front of both the first and second transmission rollers, and an adjustment component provided at the bottom of the movable frame.

[0007] Preferably, the adjusting component includes a screw, which is rotatably connected to the left side of the bottom of the positioning die-cutting equipment body. The screw is threadedly connected to the movable frame. A transmission frame is fixedly connected to the left side of the bottom of the positioning die-cutting equipment body. A transmission motor is fixedly connected inside the transmission frame. A first helical gear is fixedly connected to the output end of the transmission motor. A second helical gear meshes with the left side of the first helical gear. The second helical gear is fixedly connected to the bottom of the screw.

[0008] Preferably, a positioning rod is fixedly connected to the left side of the bottom of the positioning die-cutting equipment body, and the positioning rod is slidably connected to the moving frame. Preferably, a protective cover is fixedly connected to the bottom of the transmission frame, and the protective cover is located outside the transmission motor. Preferably, a connecting plate is fixedly connected to the outer side of the protective cover, and the positioning rod is fixedly connected to the connecting plate. Preferably, there are two positioning rods, which are located at the bottom of the positioning die-cutting equipment body. Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a drive motor. Once the drive motor is running, it drives the first helical gear connected to it to rotate. The meshing relationship between the helical gears allows the rotation of the first helical gear to effectively transmit power. The rotating first helical gear meshes with the second helical gear, thereby driving the second helical gear to rotate. This helical gear transmission method can not only change the direction of power transmission but also achieve deceleration or acceleration to a certain extent to meet the speed requirements of the screw rotation. The rotating second helical gear drives the screw connected to it to rotate. The screw has a unique helical structure. When the screw rotates, its helical characteristics can convert rotational motion into linear motion. There is a threaded fit between the screw and the moving frame. The rotation of the screw causes the moving frame to move along the axial direction of the screw. The movement of the moving frame realizes the adjustment of the distance between the first and second transmission rollers. Attached Figure Description

A first transmission roller 4 is rotatably connected to the inner side of the fixing plate 3. A movable frame 5 is slidably connected to the left side of the bottom of the positioning die-cutting device body 1. A second transmission roller 6 is rotatably connected to the inside of the movable frame 5. A servo motor 7 is fixedly connected to the front of both the first transmission roller 4 and the second transmission roller 6. An adjustment component 8 is provided at the bottom of the movable frame 5.

[0013] Please see Figure 3 The adjusting component 8 includes a screw 81, which is rotatably connected to the left side of the bottom of the positioning die-cutting equipment body 1. The screw 81 is threadedly connected to the moving frame 5. A transmission frame 82 is fixedly connected to the left side of the bottom of the positioning die-cutting equipment body 1. A transmission motor 83 is fixedly connected inside the transmission frame 82. A first helical gear 84 is fixedly connected to the output end of the transmission motor 83. A second helical gear 85 meshes with the left side of the first helical gear 84. The second helical gear 85 is fixedly connected to the bottom of the screw 81.

[0014] Furthermore, by adjusting the settings of component 8, precise control of the position of the second transmission roller 6 is achieved, enabling the equipment to adapt to protective films of various thicknesses. This adjustment function ensures the stability of the processing and transmission process, while providing great convenience to users and simplifying the operation process.

[0015] Please see Figure 3 A positioning rod 9 is fixedly connected to the left side of the bottom of the positioning die-cutting equipment body 1, and the positioning rod 9 is slidably connected to the moving frame 5.

[0016] Furthermore, the configuration of the positioning rod 9 allows for precise positioning of the moving frame 5, significantly improving its stability. This improvement effectively prevents the moving frame 5 from shaking and tilting during use, ensuring the smooth operation of the equipment and making it easier for users to operate the equipment.

[0017] Please see Figure 3 A protective cover 10 is fixedly connected to the bottom of the transmission frame 82, and the protective cover 10 is located outside the transmission motor 83.

[0018] Furthermore, the protective cover 10 provides external protection for the drive motor 83, effectively preventing damage caused by collisions with external objects. This protective measure greatly improves the safety of the equipment, ensures the stable operation of the drive motor 83, and provides users with a safer working environment.

[0019] Please see Figure 2 A connecting plate 11 is fixedly connected to the outer side of the protective cover 10, and the positioning rod 9 is fixedly connected to the connecting plate 11.

[0020] Furthermore, the configuration of the connecting plate 11 provides solid support for the bottom of the positioning rod 9, enhancing support efficiency. This design reduces the possibility of the moving frame 5 swaying, ensuring the stability of the equipment and a smooth operating experience for the user.

[0021] Please see Figure 2 There are two positioning rods 9, which are located at the bottom of the positioning die-cutting equipment body 1.

[0022] Furthermore, the number of positioning rods 9 is set to two, providing support for two key positions of the mobile frame 5. This dual-point support design improves support efficiency, effectively prevents the mobile frame 5 from shaking, and brings users a more stable and reliable user experience.

[0023] The specific implementation process of this utility model is as follows: When it is necessary to adjust the spacing of the transmission rollers in the protective mold transmission: the user starts the transmission motor 83. After the transmission motor 83 starts running, it drives the first helical gear 84 connected to it to start rotating. The meshing relationship between the helical gears allows the rotation of the first helical gear 84 to effectively transmit power. The rotating first helical gear 84 meshes with the second helical gear 85, thereby driving the second helical gear 85 to rotate. This helical gear transmission method can not only change the direction of power transmission, but also achieve the function of deceleration or acceleration to a certain extent, so as to meet the speed requirements of the screw 81. The rotating second helical gear 85 drives the screw 81 connected to it to rotate. The screw 81 has a unique helical structure. When the screw 81 rotates, its helix... The characteristics of the screw 81 enable it to convert rotational motion into linear motion. There is a threaded connection between the screw 81 and the movable frame 5. The rotation of the screw 81 causes the movable frame 5 to move along the axial direction of the screw 81. The movement of the movable frame 5 realizes the adjustment of the distance between the first transmission roller 4 and the second transmission roller 6. Because the movable frame 5 has a certain connection with the first transmission roller 4 and the second transmission roller 6, its movement will inevitably cause the distance between the two transmission rollers to change. During the movement of the movable frame 5, the positioning rod 9 plays an important role. The positioning rod 9 contacts the movable frame 5 and limits it, avoiding the movable frame 5 from deviating, shaking or other unstable situations during the movement, thereby effectively improving the stability of the movable frame 5 and ultimately achieving a good effect of easy adjustment of the distance.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
