Description

Technical Field

[0001] This utility model belongs to the technical field of release film slitting equipment, specifically a release film slitting machine. Background Technology

[0002] A slitting machine is a specialized piece of machinery widely used in industries such as papermaking, wire and cable manufacturing, mica tape production, and printing and packaging. It is mainly used to cut wide-width paper, mica tape, or film into multiple narrow strips.

[0003] In the prior art, the release film slitting machine with patent publication number CN213226461U provides a multi-blade slitting solution. Although this equipment can achieve the slitting function of release film, it still has obvious technical defects in actual use. Specifically, when adjusting the position of the blades, the operator needs to loosen the fixing bolts one by one, manually adjust the position of each blade, and then tighten them again. This adjustment method is not only cumbersome and time-consuming, but also makes it difficult to ensure the consistency of the spacing between the blades because it is adjusted manually one by one. Ultimately, this makes it difficult to control the width accuracy of the slitting product, affecting product quality.

[0004] Furthermore, this traditional adjustment method has the following problems: First, the operator's experience and skill level directly affect the adjustment accuracy, increasing the risk of human error; second, frequent adjustment operations during continuous production reduce the equipment's production efficiency; finally, due to the lack of a precise positioning device, it is difficult to achieve rapid and accurate cutter position adjustment, especially when product specifications need to be frequently changed. Therefore, developing a slitting machine that can achieve rapid, precise, and synchronous cutter adjustment is of significant practical importance. Utility Model Content

[0005] Therefore, it is necessary to provide a release film slitting machine that can quickly and synchronously adjust multiple cutters, with high precision, high efficiency, and convenient operation.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A release film slitting machine includes a slitting machine body, on which a slitting mechanism is mounted. The slitting mechanism includes a mounting plate, on which the mounting plate is mounted. A movable groove is provided at the bottom centerline of the mounting plate. First sliders are slidably connected to both ends of the movable groove. Multiple second sliders are slidably connected to the movable groove at equal intervals.

The two ends of the screw are threadedly connected to the two first sliders and slidably connected to the multiple second sliders. Motors are installed inside both ends of the mounting plate. The two ends of the screw extend into the mounting plate and are connected to the output shaft of the motor.

[0008] Optionally, in one embodiment of the present invention, the first slider, the second slider, and the movable groove are all "T" shaped structures, and the bottoms of the first slider and the second slider extend to the outside of the mounting plate.

[0009] Optionally, in one embodiment of the present invention, the cutter surface is a teardrop-shaped structure, and one end of the plurality of cutters is threadedly connected to the bottom of the first slider and the second slider by a second bolt.

[0010] Optionally, in one embodiment of the present invention, two symmetrical mounting seats are installed on the slitting machine body, and the mounting seats are provided with slots on opposite sides, and the two ends of the mounting plate engage with the two slots.

[0011] Optionally, in one embodiment of the present invention, the tops of the two mounting bases are respectively threaded with a first bolt, the first bolt extending into the slot and abutting against the mounting plate.

[0027] Example 1

[0028] Existing release film slitting machines suffer from inefficiency due to the cumbersome operation of adjusting multiple cutters. Therefore, the structure of the slitting machine has been optimized, and a release film slitting machine with convenient cutter adjustment has been designed. The specific solution is as follows:

[0029] like Figure 1-6 As shown, a release film slitting machine includes a slitting machine body 1, a slitting mechanism 2 mounted on the slitting machine body 1, and a mounting plate 201. The mounting plate 201 has a movable groove 205 at its bottom centerline. First sliders 206 are slidably connected to both ends of the movable groove 205. Multiple equidistantly distributed second sliders 207 are slidably connected to the movable groove 205. Cutting blades 208 are respectively mounted on the bottom of the two first sliders 206 and the multiple second sliders 207. A scissor-type extension is provided on the inner side of the top of the movable groove 205. The telescopic frame 212 has a rotating shaft 213 rotatably connected to its intermediate shaft. The bottom of multiple rotating shafts 213 is rotatably connected to the top center of the first slider 206 and the second slider 207, respectively. The movable groove 205 is provided with a screw 210 with opposite thread directions at both ends. The two ends of the screw 210 are threadedly connected to the two first sliders 206, and the screw 210 is slidably connected to multiple second sliders 207. Motors 211 are installed inside both ends of the mounting plate 201. The two ends of the screw 210 extend into the mounting plate 201 and are connected to the output shaft of the motor 211.

[0030] The first slider 206, the second slider 207, and the movable groove 205 are all "T" shaped structures. The bottom of the first slider 206 and the second slider 207 extends to the outside of the mounting plate 201, which facilitates the smooth sliding of the first slider 206 and the second slider 207 on the mounting plate 201 without falling off, and also facilitates the external exposure of the cutter 208 to cut the release film.

[0031] The cutter 208 has a teardrop-shaped cut surface. One end of the multiple cutters 208 is threaded to the bottom of the first slider 206 and the second slider 207 via the second bolt 209. This makes it easy to disassemble and maintain the cutter 208, and convenient to operate. At the same time, it can separate the cut release film.

[0032] The slitting machine body 1 is equipped with two symmetrical mounting seats 202. The mounting seats 202 have slots 203 on opposite sides. The two ends of the mounting plate 201 engage with the two slots 203. With the installation of the mounting seats 202 and the cooperation of the slots 203, the mounting plate 201 and the slitting machine body 1 can be detachably connected, which is beneficial for subsequent maintenance.

[0033] The top of each of the two mounting bases 202 is threaded with a first bolt 204. The first bolt 204 extends into the slot 203 and abuts against the mounting plate 201. The installation of the first bolt 204 facilitates the contact with the mounting plate 201, making the mounting plate 201 stable and securely installed inside the slot 203.

[0034] The top of the mounting plate 201 is provided with a measuring mechanism 3, which includes a slide groove 301. The top side of the mounting plate 201 is provided with a slide groove 301. The bottom of the slide groove 301 is connected to the movable groove 205. Multiple guide blocks 302 are slidably connected on the slide groove 301. The bottom of the multiple guide blocks 302 is rotatably connected to multiple rotating shafts 213 respectively. The opening of the slide groove 301 facilitates the installation of multiple guide blocks 302. The movement of the cutter 208 facilitates the movement of multiple guide blocks 302, making it easy to observe the distance between the two cutters 208.

[0035] The top of the mounting plate 201 is provided with symmetrically distributed exposed scales 303, and the two ends of the guide blocks 302 are located on one side of the exposed scales 303. The exposed scales 303 facilitate accurate observation of the distance between the guide blocks 302.

[0036] The guide block 302 has a "T" shaped structure and a diamond-shaped top, which makes it easier for the guide block 302 to mark the exposed scale 303 and accurately determine the position.

[0037] Instructions for use:

[0038] First, install the two mounting bases 202 onto the slitting machine body 1. Then, engage the two ends of the mounting plate 201 with the slots 203 on the two mounting bases 202. Next, tighten the mounting plate 201 by rotating the two second bolts 209 to ensure stable installation. Then, control the two motors 211 to drive the screw 210 to rotate, thereby driving the two first sliders 206 to drive the two ends of the scissor-type telescopic frame 212. This allows the scissor-type telescopic frame 212 to control the distance between the two first sliders 206 and the multiple second sliders 207, thus adjusting the width of the multiple cutters 208. At the same time, multiple guide blocks 302 are installed on the top of the mounting plate 201. With the cooperation of the exposed scale 303, the position of the guide blocks 302 can be observed when adjusting the width, ensuring precise adjustment of the cutters 208. After the distance between the multiple cutters 208 is adjusted, the release film is passed through the multiple cutters 208 to slit the release film.

[0039] The release film slitting machine of this solution, through the installation of the mounting plate, facilitates the sliding connection of two first sliders and multiple second sliders and makes it easy to install the cutter, thereby enabling multiple cutters to slit the release film.

[0040] The inner top of the movable slot is equipped with a scissor-type telescopic frame that works in conjunction with two first sliders and multiple second sliders to ensure that the distance between the two first sliders and the multiple second sliders is equal. The screw rotates synchronously through the synchronous operation of two motors. The reverse thread causes the two first sliders to slide synchronously in opposite directions, which can lengthen or shorten the scissor-type telescopic frame. This drives the distance between the first sliders and the second sliders to move closer or further apart, making it easier to control the cutting width. The operation is more convenient and efficient, and the cutting accuracy is ensured.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
