A lower grading roller is arranged between the fixed seats. This device has high automation efficiency, improves processing efficiency, and solves the problem of manually rotating the grading roller. However, it still has the following shortcomings:

[0003] While the aforementioned equipment can adjust the position of the pressure rollers to a certain extent to enable it to crimp different specifications of paperboard, it is not convenient to disassemble and replace the pressure rollers. Due to wear and tear on the pressure rollers after prolonged use, the precision of the crimped paperboard may be insufficient. Therefore, we propose a quick adjustment device for the crimping gap of a paper slitting machine. Utility Model Content

[0004] The purpose of this utility model is to provide a quick adjustment device for the creasing gap of a paper slitting machine. Through the adjustment mechanism and the limiting mechanism, it solves the problem that although the position of the pressure roller can be adjusted to a certain extent during the use of the above-mentioned equipment, so that it can creasing paperboard of different specifications, it is not convenient to disassemble and replace the pressure roller. As the pressure roller will wear out after long-term use, it may lead to insufficient precision of the creasing paperboard.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a quick adjustment device for the pressure line gap of a paper slitting machine, including a base, a connecting frame fixedly connected to the top outer wall of the base, and an adjustment mechanism provided on the outer wall of the connecting frame;

[0007] The adjusting mechanism includes a rotating shaft, a worm gear fixedly connected to the outer wall of the rotating shaft, a worm rotatably connected to the inner wall of the connecting frame near the worm gear, a plurality of limiting grooves formed on the inner wall of the connecting frame near the rotating shaft, a second connecting frame slidably connected to the inner wall of each of the limiting grooves, a connecting rod fixedly connected to the outer wall of the rotating shaft near the second connecting frame, a plurality of arc-shaped grooves formed on the inner wall of the connecting rod near the second connecting frame, a fixed shaft slidably connected to the inner wall of each of the second connecting frames, a pressure roller rotatably connected to the outer wall of the fixed shaft, a plurality of sliding rods slidably connected to the inner wall of the second connecting frame near the fixed shaft, a spring fixedly connected to the outer wall of each of the sliding rods, a plurality of positioning holes formed on the inner wall of the fixed shaft near the sliding rod, and a limiting mechanism provided on the outer wall of the base.

[0008] Furthermore, the outer wall of the rotating shaft is rotatably connected to the central axis of the top outer wall of the connecting frame, and the outer wall of the worm gear meshes with the outer wall of the worm wheel.

[0009] Furthermore, the inner wall of the arc-shaped groove is slidably connected to the outer wall of the connecting frame two, and the outer wall of the slide rod is inserted into the inner wall of the positioning hole.

[0010] Furthermore, the limiting mechanism includes several fixing blocks, and the outer walls of the fixing blocks are all fixedly connected to the outer wall of the base.

[0011] Furthermore, the inner walls of several fixed blocks are rotatably connected to fixed shafts II, and the outer walls of several fixed shafts II are rotatably connected to connecting rods II.

[0012] Furthermore, each of the connecting rods 2 has an arc-shaped groove 2 on its inner wall near the connecting frame, and a top plate is slidably connected to the inner wall of each of the arc-shaped grooves 2.

[0013] Furthermore, each of the connecting rods 2 has an arc-shaped groove 3 on its inner wall at the end away from the arc-shaped groove 2, and each of the arc-shaped groove 3 has a limit block slidably connected to its inner wall.

[0014] Furthermore, the inner wall of the limiting block is threaded with a bidirectional threaded rod, the outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the base, and the inner wall of the connecting frame near the top plate is provided with several sliding grooves, the inner wall of the sliding grooves is slidably connected to the outer wall of the top plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a limiting slide groove in the connecting frame, allows for the adjustment of the crease spacing of the cardboard when the equipment needs to be used. When the cardboard is pulled out, one or more pressure rollers can be selected for simultaneous use according to actual needs. Multiple slide rods are pulled upwards to compress the springs. After the slide rods are completely pulled out of the positioning holes, the fixed shaft can be pulled out from both sides, and then one pressure roller can be removed from the connecting frame. This allows users to freely adjust the position of the pressure rollers according to their actual crease requirements for the cardboard, facilitating the pressing of creases at different spacings on the cardboard. Simultaneously, the pressure rollers are easy to install and disassemble, making it convenient for users to replace or maintain them later.

[0017] 2. This utility model incorporates limiting blocks on a bidirectional threaded rod. During equipment use, the cardboard is first placed on the base, positioned between the top plates. Then, the bidirectional threaded rod is rotated. This rotation simultaneously causes the limiting blocks on both sides to slide within the arc-shaped groove three. Consequently, the connecting rod two rotates around the fixed shaft two. As the connecting rod two rotates, it drives the top plate to slide linearly within the groove through the arc-shaped groove two. When the top plate slides towards the center simultaneously, it effectively limits the position of the cardboard during the creasing process, preventing displacement that could lead to insufficient creasing accuracy or even creasing failure.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a quick adjustment device for the pressure gap of a paper slitting machine, including a base 1. A connecting frame 101 is fixedly connected to the top outer wall of the base 1. An adjustment mechanism 2 is provided on the outer wall of the connecting frame 101. The position of the rotating shaft 201 can be limited by the connecting frame 101 to prevent it from falling off.

[0029] Adjustment mechanism 2 includes a rotating shaft 201, a worm gear 202 fixedly connected to the outer wall of the rotating shaft 201, and a worm 203 rotatably connected to the inner wall of the connecting frame 101 near the worm gear 202. Several limiting grooves 204 are provided on the inner wall of the connecting frame 101 near the rotating shaft 201. The connecting frame 101 limits the position of the rotating shaft 201 to prevent it from falling off. The limiting grooves 204 limit the movement trajectory of the connecting frame 206, ensuring it can only slide within the connecting frame 206, preventing it from falling off. The inner walls of the limiting grooves 204 are all slidably connected to the connecting frame 206. A connecting rod 205 is fixedly connected to the outer wall of the rotating shaft 201 near the connecting frame 206. Several arc-shaped grooves are provided on the inner wall of the connecting rod 205 near the connecting frame 206. 212. Fixed shafts 207 are slidably connected to the inner walls of several connecting frames 206. The arc-shaped grooves 212 can limit the movement trajectory of the connecting frames 206 and prevent the connecting rods 205 from jamming when driving the connecting frames 206. Pressure rollers 208 are rotatably connected to the outer wall of the fixed shafts 207. Several sliding rods 209 are slidably connected to the inner wall of the connecting frame 206 near the fixed shafts 207. Springs 210 are fixedly connected to the outer walls of the sliding rods 209. Several positioning holes 211 are opened on the inner wall of the fixed shaft 207 near the sliding rods 209. The outer wall of the base 1 is provided with a limit mechanism 3. Through the positioning holes 211, when the sliding rods 209 are inserted into the positioning holes 211, the position of the fixed shaft 207 can be limited to prevent the fixed shaft 207 from slipping out of the connecting frame 206.

[0030] The outer wall of the rotating shaft 201 is rotatably connected to the central axis of the top outer wall of the connecting frame 101. The outer wall of the worm 203 meshes with the outer wall of the worm wheel 202. The inner wall of the arc groove 212 is slidably connected to the outer wall of the connecting frame 206. The outer wall of the slide rod 209 is inserted into the inner wall of the positioning hole 211. The limiting mechanism 3 includes several fixing blocks 301. The fixing blocks 301 can limit the position of the fixing shaft 302, so that it can only rotate within the fixing blocks 301. At the same time, it can prevent the fixing shaft 302 from falling off. The outer walls of the several fixing blocks 301 are all fixedly connected to the outer wall of the base 1. The inner walls of the several fixing blocks 301 are rotatably connected to the fixing shaft 302. The outer walls of the several fixing shafts 302 are rotatably connected to the connecting rod 303. The fixing shaft 302 can limit the position of the connecting rod 303 and prevent the connecting rod 303 from falling off.

[0031] Several connecting rods 303 have arc-shaped grooves 304 on their inner walls near the connecting frame 101. Top plates 305 are slidably connected to the inner walls of these arc-shaped grooves 304. Arc-shaped grooves 306 are also formed on the inner walls of the connecting rods 303 away from the arc-shaped grooves 304. These arc-shaped grooves 306 limit the movement trajectory of the limiting block 307 and prevent jamming during movement. Limiting blocks 307 are slidably connected to the inner walls of these arc-shaped grooves 306, and the inner walls of the limiting blocks 307 are threaded together. A bidirectional threaded rod 308 is connected, and the outer wall of the bidirectional threaded rod 308 is rotatably connected to the inner wall of the base 1. When the user rotates the bidirectional threaded rod 308, the rotation of the bidirectional threaded rod 308 can drive the limiting block 307 to move in the arc-shaped groove 306. Several sliding grooves 309 are opened on the inner wall of the end of the connecting frame 101 near the top plate 305. The inner wall of the sliding groove 309 is slidably connected to the outer wall of the top plate 305. The sliding groove 309 can limit the movement trajectory of the top plate 305, so that it can only slide in a straight line in the connecting frame 101 along the direction of the sliding groove 309.

[0032] One specific application of this embodiment is:

[0033] When the operator needs to use the equipment, first place the cardboard on the base 1, positioning it between the top plates 305. Then, rotate the bidirectional threaded rod 308. The rotation of the bidirectional threaded rod 308 simultaneously drives the limiting blocks 307 on both sides to slide within the arc-shaped groove 306. This causes the connecting rod 303 to rotate around the fixed shaft 302. When the connecting rod 303 rotates, it drives the top plate 305 to slide linearly within the slide groove 309 through the arc-shaped groove 304. When the top plate 305 slides towards the center and presses against both sides of the cardboard, the position of the cardboard is limited, preventing displacement during subsequent creasing. After the position of the cardboard is limited, pull the cardboard back and forth. Since the pressure roller 208 at the top presses against the cardboard, the movement of the cardboard will drive the pressure roller 208 to rotate on the fixed shaft 207, thus pressing it against the pressure roller 208. For line processing, when it is necessary to adjust the crease spacing of the cardboard, when the cardboard is pulled out, select one or more pressure rollers 208 to use simultaneously according to actual needs. Pull multiple slide bars 209 upward to compress the spring 210. After the slide bars 209 are completely pulled out from the positioning hole 211, the fixed shaft 207 can be pulled out from both sides. Then, one pressure roller 208 can be removed from the connecting frame 206, leaving only one pressure roller 208 for use. Then, rotate the worm gear 203. The rotation of the worm gear 203 can drive the worm wheel 202 to rotate, causing the rotating shaft 201 to rotate. When the spring 210 rotates, it will drive the connecting rod 205 to rotate. When the connecting rod 205 rotates, it will drive the connecting frame 206 to slide left and right in the limiting slide groove 204 through the arc groove 212, thereby controlling the position of the pressure roller 208 and performing crease processing on different positions on the cardboard.
