Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically a cutting structure for a slitting machine. Background Technology

[0002] After the production of craft products such as hot stamping foil and glitter paper is completed, they need to be cut into specified sizes and shapes using a slitting machine according to requirements.

[0003] For example, patent CN220945548U discloses an automatic slitting machine for label cutting, including an equipment platform, a cutting spacing adjustment unit, a cutting unit, and a synchronous conveying unit. The equipment platform is a rectangular plate. The cutting spacing adjustment unit includes an adjustment sleeve, a slide rod, a vertical plate, a threaded sleeve, a threaded rod, a motor mounting plate, and a motor. The middle of the front and rear ends of the upper surface of the equipment platform are respectively fixedly connected to the bottom ends of the vertical plate. The top ends of the vertical plate are respectively fixedly connected to the two ends of the slide rod. The slide rod is slidably connected to the adjustment sleeve. The bottom end of the slide rod is fixedly connected to the threaded sleeve. The threaded sleeve is threadedly connected to the threaded rod. The two ends of the threaded rod are respectively rotatably connected to and pass through the corresponding positions of the vertical plate. However, the existing device cannot adjust the cutting depth. If the cutting depth is too shallow, the material may not be completely cut off, resulting in uneven slitting edges, which affects the subsequent processing or packaging effect. In addition, manual pushing is required during the material conveying process, which reduces production efficiency.

[0004] Therefore, in order to solve such problems, we propose a cutting structure for a slitting machine. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting structure for a slitting machine to solve the problems mentioned in the background art, such as the inability to adjust the cutting depth, the possibility that the material may not be completely cut off due to the shallow cutting depth, resulting in uneven cutting edges, affecting subsequent processing or packaging effects, and the need for manual pushing during the material conveying process, which reduces production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting structure for a slitting machine, comprising a support plate and a base fixedly connected to the bottom of the support plate, a bracket fixedly connected to one side of the top of the support plate, a second motor fixedly connected to the upper part of one side of the bracket, the output end of the second motor passing through the bracket, a rotating disk fixedly connected to the output end of the second motor, an eccentric bolt fixedly connected to the side of the rotating disk away from the second motor, an adjustable support rod sleeved on the eccentric bolt, a connecting rod movably connected below the adjustable support rod, and a cutting component fixedly connected to one side of the connecting rod.

[0007] Furthermore, the bracket has limit grooves at both ends of the outer wall on the side away from the second motor, and limit blocks are fixedly connected to both ends of the outer wall on the side of the connecting rod near the bracket, with the limit blocks sliding within the limit grooves.

[0008] Furthermore, a groove is provided on one side of the top of the support plate, and a first motor is fixedly connected to the outer wall of the support plate near the groove. A lead screw is fixedly connected to the output end of the first motor, the lead screw passes through the support plate, and a slider is threaded onto the lead screw. A limit plate is fixedly connected to the top of the slider.

[0009] Furthermore, a cutting groove is provided on the limiting plate, and a rotating roller is rotatably connected in the groove of the limiting plate.

[0010] Furthermore, a U-shaped component is fixedly connected to one end of the top of the limiting plate, a ratchet is rotatably connected to the U-shaped component, and a transmission roller is fixedly connected to the rotating end of the ratchet.

[0011] Furthermore, a fixing plate is fixedly connected to the side of the connecting rod away from the cutting part, and a locking block is elastically rotated by a torsion spring on the lower part of the outer wall of the fixing plate away from the connecting rod.

[0012] Furthermore, the slider is located within the slide groove, and the support plate and the limiting plate are slidably connected to the slide groove via the slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the cutting structure for the slitting machine adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The cutting structure used in the slitting machine can adjust the vertical position of the cutting parts by setting components such as eccentric bolts and adjustable support rods. The cutting depth can be flexibly adjusted according to the thickness of different materials and slitting requirements. The circumferential movement of the eccentric bolt can better slitting the materials, avoiding the situation where the cutting depth is too shallow, resulting in the material not being completely cut off and the cutting edge being uneven. This improves the slitting quality and meets the high precision requirements of subsequent processing or packaging.

[0015] (2) The cutting structure used in the slitting machine utilizes the synergistic effect of ratchet, transmission roller and clamping block to realize automatic feeding of the material to be cut, which changes the traditional slitting machine that requires manual material pushing. This not only improves production efficiency but also reduces labor costs. At the same time, it ensures the stability of the material feeding process and is conducive to improving the cutting accuracy.

[0016] Furthermore, the limiting groove on the support cooperates with the limiting block on the connecting rod, so that the connecting rod can only slide along the limiting groove during the movement, effectively limiting the movement trajectory of the connecting rod, ensuring the stability of the cutting part during the cutting process, and further improving the accuracy and reliability of the cutting. The support plate and the limiting plate are slidably connected by a slider and a slide groove, ensuring the smooth movement of the limiting plate and providing a stable support structure for material conveying and cutting.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides the following technical solution: a cutting structure for a slitting machine.

[0026] Example 1: A cutting structure for a slitting machine, wherein the vertical position of the cutting piece 26 can be adjusted by means of components such as an eccentric bolt 231 and an adjustable support rod 24, for example... Figure 1 - Figure 4As shown, a cutting structure for a slitting machine includes a support plate 1 and a base 3 fixedly connected to the bottom of the support plate 1. A bracket 2 is fixedly connected to one side of the top of the support plate 1. A second motor 22 is fixedly connected to the upper part of one side of the outer wall of the bracket 2. The output end of the second motor 22 passes through the bracket 2. A rotating disk 23 is fixedly connected to the output end of the second motor 22. An eccentric bolt 231 is fixedly connected to the side of the rotating disk 23 away from the second motor 22. An adjustable support rod 24 is sleeved on the eccentric bolt 231. A connecting rod 25 is movably connected to the lower part of the adjustable support rod 24. A cutting piece 26 is fixedly connected to one side of the outer wall of the connecting rod 25. Limiting grooves 21 are opened at both ends of the outer wall of the bracket 2 away from the second motor 22. Limiting blocks 251 are fixedly connected to both ends of the outer wall of the connecting rod 25 near the bracket 2. The limiting blocks 251 slide within the limiting grooves 21.

[0027] First, the second motor 22 is started, which drives the rotating disk 23 to rotate. The eccentric bolt 231 on the rotating disk 23 then makes a circular motion. Since the eccentric bolt 231 is fitted with an adjustable support rod 24, the adjustable support rod 24 will move up and down with the rotation of the eccentric bolt 231, thereby driving the connecting rod 25 connected below to move up and down. The cutting part 26 fixed on one side of the outer wall of the connecting rod 25 will also move up and down, realizing the adjustment of the cutting depth. During this process, the limiting block 251 slides in the limiting groove 21, which plays a guiding and limiting role, ensuring the stability and accuracy of the movement of the connecting rod 25 and the cutting part 26.

[0028] Example 2: Unlike Example 1, the material to be cut is conveyed through a ratchet 151, a transmission roller 152, and a locking block 271, resulting in a stable structure. Figure 5 - Figure 6 As shown, a groove 11 is provided on one side of the top of the support plate 1. A first motor 12 is fixedly connected to the outer wall of the support plate 1 near the groove 11. A lead screw 121 is fixedly connected to the output end of the first motor 12. The lead screw 121 passes through the support plate 1. A slider 122 is threaded onto the lead screw 121. A limit plate 13 is fixedly connected to the top of the slider 122. A cutting groove 131 is provided on the limit plate 13. A rotating roller 14 is rotatably connected to the groove of the limit plate 13. 3. A U-shaped piece 15 is fixedly connected to one end of the top. A ratchet 151 is rotatably connected to the U-shaped piece 15. A transmission roller 152 is fixedly connected to the upper part of the rotating end of the ratchet 151. A fixing plate 27 is fixedly connected to the side of the connecting rod 25 away from the cutting piece 26. A locking block 271 is elastically rotated below the outer wall of the fixing plate 27 away from the connecting rod 25 by a torsion spring. The slider 122 is located in the slide groove 11, and the support plate 1 and the limiting plate 13 are slidably connected to the slide groove 11 through the slider 122.

[0029] The first motor 12 is started, which drives the lead screw 121 to rotate. The slider 122, which is threaded on the lead screw 121, moves along the slide groove 11 under the rotation of the lead screw 121, thereby driving the limit plate 13 to move. When the connecting rod 25 moves downward, the locking block 271 under the fixed plate 27 will contact the ratchet 151 and push the ratchet 151 to rotate. The ratchet 151 drives the transmission roller 152 to rotate. When the transmission roller 152 rotates, it will drive the material to be cut placed on its surface to be conveyed forward. When the connecting rod 25 moves upward, the locking block 271 is lifted upward under the action of the torsion spring and disengages from the ratchet 151. The ratchet 151 will not rotate in the opposite direction, and thus the transmission roller 152 will not rotate in the opposite direction, thereby realizing the unidirectional conveying of materials and ensuring the smoothness of material conveying.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] 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.
