Description

Technical Field

[0001] The utility model relates to the technical field of cigarette box production, in particular to a material cutting device for cigarette box production. Background Art

[0002] The outer packaging paper of cigarettes needs to go through processes such as printing, hot stamping, and die-cutting before being made into boxes. Among them, in the traditional die-cutting process, a cutting device is needed to cut the raw paper.

[0003] Chinese patent CN221892658U discloses a cutting device for cigarette box production. The cutting device can easily install and disassemble the cutting blade assembly, making it easy to replace the cutting blade assembly according to the structure of the cigarette box. The operation is simple, and the anti-slip pad has friction, which can improve the placement stability of the cutting blade assembly and bring better use prospects. However, while solving the problems, the cutting device has the following defects:

[0004] When replacing the cutting knife group, multiple telescopic rods, a second cylinder and a first cylinder need to be used together. The structure is complicated, and multiple telescopic rods and a second cylinder are provided on both sides of the fixed frame, which undoubtedly increases the cost of the equipment and is therefore not easy to promote. Utility Model Content

[0005] The purpose of the present invention is to at least solve one of the technical defects described in the background technology.

[0006] Therefore, one purpose of the present invention is to provide a cutting device for cigarette box production, aiming to solve the problem that the cutting equipment for cigarette box production in the prior art is high in cost and difficult to promote.

[0007] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the present invention provides a cutting device for cigarette box production, including a cutting table, a support frame is fixedly connected to the rear side of the top of the cutting table, a cylinder is fixedly installed on the top of the support frame, a piston rod end of the cylinder is fixedly connected to a joint, both sides of the joint are slidably connected to a traction rod, the bottom end of the traction rod is fixedly connected to a splint, a limiting plate is hinged between the two splints, a fixing plate is clamped between the two splints, a cutting knife group is fixedly installed on the bottom of the fixing plate, the internal thread of the bottom end of the joint is connected to a positioning screw, and the bottom end of the positioning screw is fixedly connected to a support seat.

[0008] The beneficial effects are as follows: when replacing the cutting knife group, the positioning screw is rotated to raise the support seat, and then the cutting knife group is lowered. After the cutting knife group contacts the cutting table, the traction rod will slide on the surface of the slide rod through the slide groove, so that the bottom of the two clamps are opened, thereby loosening the fixed plate.

When installing the cutting knife group, the joint is lowered, and the limit plate is held by hand at the same time, so that the two clamps are in an open state. When the limit plate contacts the fixed plate above the cutting knife group, the limit plate is loosened, and then the joint is raised, and the bottom of the two clamps are brought together to clamp the fixed plate, thereby completing the replacement of the cutting knife group. Only one cylinder is required to control the replacement of the cutting knife group. The structure is simple and the cost is low, which makes it easy to promote.

[0009] Preferably, any of the above schemes is provided with two symmetrical grooves on both sides of the fixing plate, a hook groove is provided at the bottom of the groove, and a hook is fixedly connected to the bottom of the inner side of the splint.

[0010] The beneficial effect is that when the two clamping plates clamp the fixed plate, the hook can be hung in the hook groove, thereby avoiding the problem of the fixed plate sliding downward during the rising process, and improving the reliability of the structure.

[0011] Preferably, any of the above schemes is that a pull rope is fixedly connected to one side of the joint, an end of the pull rope is fixedly connected to an insertion rod, and a plug hole is provided on the side of the limiting plate.

[0012] The beneficial effect is that when disassembling and assembling the cutting knife group, the insertion rod is inserted into the insertion hole to limit the distance between the limit plate and the joint, so that the bottoms of the two clamping plates are in an open state, so that the process of disassembling and assembling the cutting knife group does not require manual support, further improving the convenience of replacing the cutting knife group.

For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0023] The utility model provides a material cutting device for producing cigarette boxes.

[0024] Example 1:

[0025] like Figure 1-5As shown, it includes a cutting table 1, the rear side of the top of the cutting table 1 is fixedly connected to a support frame 11, the top of the support frame 11 is fixedly installed with a cylinder 2, the piston rod end of the cylinder 2 faces downward, the piston rod end of the cylinder 2 is fixedly connected to a joint 21, both sides of the joint 21 are slidably connected to a traction rod 3, the outer surface of the joint 21 is fixedly connected to two symmetrical fixed blocks 211, both sides of the fixed block 211 are fixedly connected to a slide bar 212, a side of the traction rod 3 is provided with a slide groove 34, the slide bar 212 is slidably connected in the slide groove 34, the bottom end of the traction rod 3 is fixedly connected to a splint 31, and the two splints 31 are hinged with each other. The limiting plate 4 and one side of the top of the splint 31 are fixedly connected with a positioning block 32. Positioning grooves 41 are provided on both sides of the limiting plate 4. The positioning block 32 is hinged in the positioning groove 41. The limiting plate 4 limits the distance between the two splints 31 to avoid the problem of the two splints 31 being close together when the joint 21 rises. A guide hole 12 is provided on the top of the support frame 11. A guide rod 42 is fixedly connected to the rear side of the top of the limiting plate 4. The guide rod 42 is slidably inserted in the guide hole 12 to limit the moving direction of the limiting plate 4, which can avoid the problem of the limiting plate 4 being skewed. A fixing plate 5 is clamped between the two splints 31. Figure 1 As shown, when the piston rod of the cylinder 2 contracts and drives the joint 21 to rise, the slide bar 212 slides in the slide groove 34, so that the bottoms of the two clamping plates 31 are brought together. Two symmetrical grooves 51 are provided on both sides of the fixed plate 5, so that the clamping plates 31 can be clamped in the grooves 51 on both sides of the fixed plate 5. Continuing to rise the joint 21 can drive the fixed plate 5 to rise, and a hook groove 52 is provided at the bottom of the groove 51. The bottom of the inner side of the clamping plate 31 is fixedly connected with a hook 33. The hook 33 can be hung in the hook groove 52, thereby avoiding the problem of the fixed plate 5 sliding downward during the rising process. The cutting knife group 6 is fixedly installed at the bottom of the fixed plate 5. The cutting knife group 6 is lowered. When the cutting knife group 6 contacts the top surface of the cutting table 1, the joint 21 is continued to be lowered. At this time, it can be lowered. The traction rod 3 is pressed so that the bottoms of the two clamping plates 31 move away from each other. At this time, the clamping plates 31 can be loosened from the fixing plate 5. The internal thread at the bottom end of the joint 21 is connected to the positioning screw 22, and the bottom end of the positioning screw 22 is fixedly connected to the support seat 23. After the joint 21 drives the fixing plate 5 to rise, the positioning screw 22 is rotated to press the support seat 23 on the top of the limit plate 4. At this time, when the cutting knife group 6 is lowered to cut the raw paper of the cigarette box, the joint 21 can press the limit plate 4 down through the positioning screw 22 and the support seat 23, and then press the fixing plate 5 through the limit plate 4, thereby applying force to the cutting knife group 6 to achieve the purpose of cutting the raw paper of the cigarette box. During this process, the two clamping plates 31 will not loosen the fixing plate 5. Therefore, when the joint 21 is raised, the fixing plate 5 will not fall.

[0026] The working principle of the present invention is as follows: when using, when replacing the cutting knife group 6, rotate the positioning screw 22 to make the support seat 23 rise, then extend the cylinder 2, make the cutting knife group 6 contact the cutting table 1, continue to lower the joint 21, because the limit plate 4 resists the fixed plate 5 and cannot continue to fall, so the traction rod 3 will slide on the surface of the slide rod 212 through the slide groove 34, so that the bottom of the two clamping plates 31 is opened, thereby loosening the fixed plate 5, at this time, raise the joint 21 again, and lift the limit plate 4 upward at the same time, so that the fixed plate 5 and the cutting knife group 6 can be lowered. The group 6 is removed, and then the new cutting knife group 6 is placed on the cutting table 1, and then the joint 21 is lowered, and at the same time, the limit plate 4 is held by hand so that the two clamps 31 are in an open state. When the limit plate 4 contacts the fixed plate 5 above the cutting knife group 6, the limit plate 4 is released, and then the joint 21 is raised. The bottom of the two clamps 31 are brought close together, thereby clamping the fixed plate 5, and then the cutting knife group 6 can be driven to rise. Finally, the positioning screw 22 is rotated so that the support seat 23 contacts the top of the limit plate 4, thereby completing the replacement of the cutting knife group 6.

[0027] Example 2:

[0028] like Figure 1 As shown, on the basis of embodiment 1, a pull rope 24 is fixedly connected to one side of the joint 21, and an insertion rod 25 is fixedly connected to the end of the pull rope 24. A socket 43 is provided on the side of the limit plate 4. When the cutting knife group 6 is removed, the cutting knife group 6 contacts the cutting table 1, and the bottoms of the two clamping plates 31 are opened. After loosening the fixing plate 5, the insertion rod 25 is inserted into the socket 43, thereby limiting the distance between the joint 21 and the limit plate 4. At this time, the joint 21 is raised again, and the limit plate 4 can be lifted upward by the pull rope 24. At this time, the two clamping plates 31 are in an open state, thereby completing the disassembly of the cutting knife group 6. When installing a new cutting knife group 6, the limit plate 4 is directly lowered. Since each clamping plate 31 is in an open state next year, the bottom of the limit plate 4 can be smoothly overlapped with the top of the fixed plate 5. At this time, the insertion rod 25 is pulled out from the insertion hole 43, and then the joint 21 is raised, so that the two clamping plates 31 can clamp the fixed plate 5. Finally, the positioning screw 22 is rotated to make the support seat 23 contact the top of the limit plate 4.
