Description

Technical Field

[0001] The utility model relates to the technical field of film processing equipment, in particular to a film slitting and positioning device. Background Art

[0002] Film is a thin, soft, transparent sheet made of plastic, adhesive, rubber, or other materials. Film is often used for packaging and other purposes, such as protection and preservation. Formed through polyaddition or polycondensation reactions, it is a polymer compound, commonly known as plastic or resin, that can freely change its composition and shape. It consists of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The existing film production process requires cutting the produced film into sections of varying lengths to meet market demand. In the existing technology, when replacing the winding core, an operator manually marks the winding roll with a marker and then moves the core to a set position to secure it. However, manual adjustment of the winding core is prone to errors and cannot align it with the winding core on the other roll, resulting in deviations between adjacent winding cores. During winding, adjacent film edges rub against each other, causing damage and compromising the quality of the film after slitting. To address this issue, a film slitting and positioning device is proposed. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] A film cutting and positioning device, such as Figure 1 、 Figure 4 、 Figure 5 As shown, it includes a frame 1; a winding mechanism 2 is provided on the frame 1, and the winding mechanism 2 can perform a winding operation on the film.

[0027] Specifically, the winding mechanism 2 includes a winding roller 201, which is rotatably connected to the inner side of the frame 1. There are two winding rollers 201, which can support the entire winding mechanism 2. At the same time, the other end of the winding roller 201 is an open structure, which can support the end of the winding roller 201 with a support structure that slides on the frame 1, thereby improving the rotation stability of the winding roller 201. The winding roller 201 is movably connected to a winding core 202. The winding core 202 structure can be easily installed and inserted into the outside of the winding roller 201 or removed from the winding roller 201. The winding core 202 includes models of different widths, which facilitates slitting the film into various widths. The winding roller 201 is internally rotatably connected to a screw 203, and the screw 203 is meshed with a drive block 204 on the outside. The screw 203 can drive the drive block 204, and the position of the winding core 202 is adjusted by the drive block 204. A cutter is slidably connected to the frame 1, and the cutter structure can perform a cutting operation on the film.

[0028] Furthermore, a movable block 205 is slidably connected to the outside of the screw 203. The winding core 202 is connected to the movable block 205 and the driving block 204. By adjusting the movable block 205 and the driving block 204, the winding core 202 can be synchronously adjusted to meet the needs of slitting of different widths. Buffer springs 206 are fixedly connected to the sides of the driving block 204 and the sides of the movable block 205. The buffer springs 206 can control the spacing between the movable blocks 205 and the spacing between the movable blocks 205 and the driving block 204. Because the buffer springs 206 have the same elasticity, when the buffer springs 206 are squeezed, the pressure can be distributed to different buffer springs 206, so that the buffer springs 206 are subjected to the same force, thereby ensuring that the spacing between the movable blocks 205 and the spacing between the movable blocks 205 and the driving block 204 are the same. A movable groove 207 is provided on the side of the winding roller 201, and a positioning block 208 is fixedly connected to the driving block 204 and the movable block 205. The positioning block 208 is connected inside the movable groove 207. The movable groove 207 structure can cooperate with the positioning block 208. When the screw 203 drives the driving block 204, the driving block 204 is limited to prevent the driving block 204 from rotating with the screw 203.

[0029] Furthermore, a positioning ball 209 is slidably connected to the inside of the winding core 202, and a positioning spring 210 is connected to the inside of the positioning ball 209. The slidably connected positioning ball 209 can be moved outward by the elastic action of the positioning spring 210, thereby positioning the winding core 202. The positioning block 208 is provided with a positioning groove 211 that corresponds to the positioning ball 209. The positioning groove 211 has a ∠-shaped structure, which can position the winding core 202 on the driving block 204 or the moving block 205, thereby allowing the winding performance to be adjusted as the driving block 204 and the moving block 205 move.

[0030] Example 2

[0031] like Figure 2 、 Figure 3 、 Figure 6 As shown, based on Example 1, a driving mechanism 3 is provided on the frame 1, and the driving mechanism 3 can drive the winding so that the slit film is wound through the winding core 202.

[0032] In this embodiment, the drive mechanism 3 includes a transmission gear 301, which is fixedly connected to the end of the screw 203. The side of the transmission gear 301 is meshed with a driven gear 302. The driven gear 302 can transmit power to the two transmission gears 301. At the same time, the winding roller 201 can be moved and adjusted, and moves around the driven gear 302 during the adjustment process, so that the transmission gear 301 remains meshed with the driven gear 302. At the same time, one of the transmission gears 301 is meshed with a steering gear, which meshes with the driven gear 302, so that the two winding rollers 201 can rotate in opposite directions. The driven gear 302 is rotatably connected to the side of the frame 1, and the frame 1 can support the driven gear 302.

[0033] On this basis, a motor 303 is fixedly connected to the frame 1, and a driving gear 304 is fixedly connected to the end of the output shaft of the motor 303. The driving gear 304 and the driven gear 302 are meshed with each other. The motor 303 structure can drive the driven gear 302 through the driving gear 304, so that the driven gear 302 rotates continuously.

[0034] Furthermore, a support frame 305 is fixedly connected to the frame 1, and an adjustment frame 306 is slidably connected to the support frame 305. An adjustment rod 307 is movably connected to the inner side of the adjustment frame 306. The end of the adjustment rod 307 is fixedly connected to the transmission gear 301. The adjustment structure can adjust the movement of the transmission gear 301. The support frame 305 has an arc-shaped structure, which can guide the movement of the adjustment rod 307.

[0035] It is worth noting that the end of the screw 203 is fixedly connected to a limit block 308, and a limit slot 309 is provided on the inside of the winding roller 201, which corresponds to the limit block 308 structure. The limit block 308 structure can cooperate with the limit slot 309 structure to allow the screw 203 to rotate inside the winding roller 201 or to rotate synchronously with the winding roller 201. The outside of the winding roller 201 and the frame 1 are fixedly connected to a limit tooth 310. The limit tooth 310 structure can position the winding roller 201, so that the winding roller 201 can be limited after the limit block 308 is disengaged from the limit slot 309.

[0036] When using a film slitting and positioning device according to the present invention, the winding core 202 of a set model is first placed on the outside of the winding roller 201 and moved along the winding roller 201 toward the other end. After the winding core 202 moves to a position corresponding to the driving block 204, the winding core 202 is rotated so that the positioning ball 209 on the inside of the winding core 202 rotates to the positioning groove 211, and the installation of a single winding core 202 is completed. The remaining winding cores 202 are then placed on the outside of the winding roller 201 in sequence and installed on the moving block 205 in the same manner. After all the winding cores 202 are installed, the adjustment frame 306 is moved, and the adjustment rod 307 on the inside of the adjustment frame 306 moves along the arc-shaped support frame 305 and drives the winding rollers 201 to move synchronously until the winding rollers 201 approach each other. The adjustment frame 306 is then pushed outward, which in turn pushes the screw 203 until the stop block 308 on the side of the screw 203 moves away from the stop slot 309. Simultaneously, the stop block 308 pushes the winding roller 201 inward, causing the stop teeth 310 on the winding roller 201 to contact the stop teeth 310 on the frame 1, thereby limiting the position of the winding roller 201. At this point, the winding cores 202 on the two winding rollers 201 are alternately positioned. The motor 303 is then started, which drives the driven gear 302 via the drive gear 304, thereby rotating the transmission gear 301. The screw 203 inside the transmission gear 301 then rotates, pushing the drive block 204 toward the moving block 205. The drive blocks 204 within the two winding rollers 201 move synchronously with this, driven by the buffer springs 206, which in turn drive the moving blocks 205. During movement, the elastic action of the buffer springs 206 maintains consistency between the moving blocks 205 and the spacing between them and the drive blocks 204. The moving blocks 205 and the drive blocks 204 drive the winding cores 202 in sync during movement. When the winding cores 202 contact the adjacent winding cores 202 at either end, the motor 303 stops. At this point, the slitting blades are moved adjacent to the winding cores 202. After adjustment is complete, the adjustment frame 306 is pushed inward, pushing the screw 203 until the stop block 308 on the side of the screw 203 moves into the stop slot 309. Simultaneously, the stop block 308 pushes the winding rollers 201 inward, disengaging the stop teeth 310 on the winding rollers 201 from those on the frame 1. The adjusting frame 306 is then moved, and the adjusting rod 307 moves the winding rollers 201 away from each other. The motor 303 is then started again, and the transmission gear 301 rotates again. Now, due to the constraints of the limit block 308 and the limit slot 309, the screw 203 and the winding roller 201 rotate synchronously, and the slit film is wound through the winding core 202.
