Description

Technical Field

[0001] This utility model relates to the field of slitting machines, and more particularly to a slitting machine for sheet production. Background Technology

[0002] Sheet materials are widely used in industries such as plastics, packaging, textiles, and electronics. Downstream industries have diverse needs for sheets of different widths. For example, the packaging industry needs to cut wide plastic sheets into strips that fit packaging sizes, while the electronics industry needs to cut metal foil into fine widths for circuit boards. Slitting machines have become key equipment in the sheet processing industry chain, meeting the needs of precise material cutting and adapting to diverse production requirements.

[0003] Existing slitting machines operate fully automatically, covering feeding, positioning, slitting to output, reducing manual intervention, completing a large number of slitting tasks in a short time, improving production speed, and enabling continuous operation. They are suitable for large-scale production and can adapt to various roll materials such as plastics, paper, and metals. By changing parts, they can meet the processing needs of different thicknesses, widths, and shapes. Some models can also be used for multiple purposes. They are equipped with a user-friendly human-machine interface, making operation simple and intuitive. Some models support intelligent functions such as program self-design and tool life detection, reducing the skill requirements for operators.

[0004] However, existing slitting machines have some problems in actual use. They cannot adapt to the width of the sheet and cannot change blades quickly, which can cause the sheet to deviate from the track during transportation, resulting in uneven cutting and increased scrap rate. The inability to change blades quickly leads to long blade change time and a significant reduction in production efficiency. Therefore, a slitting machine for sheet production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a slitting machine for sheet production, which aims to improve the problems of low production efficiency caused by excessively long blade changing time and uneven cutting caused by roll material deviation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sheet slitting machine includes a support frame, an unwinding shaft rotatably connected inside the support frame, a roll of material disposed outside the unwinding shaft, a quick-change tool assembly fixedly connected inside the support frame, and a clamping assembly fixedly connected to the top of the support frame.

[0008] The quick tool changer includes multiple clamping plates, which are fixedly connected inside the bracket. Two clamping plates are fixedly connected to the outer wall of the clamping plates. A shaft is provided inside the bracket, and a clamping plate is slidably connected inside the shaft. A spring is provided inside the shaft, and both ends of the spring are fixedly connected to the outer walls of the two clamping plates. The clamping plates are slidably connected inside the shaft, and multiple tool sleeves are slidably connected to the outer wall of the shaft. The outer wall of the clamping plates is slidably connected to the inside of the tool sleeves, and a blade is fixedly connected to the outer wall of the tool sleeves.

[0014] The bracket is fixedly connected to a guide rail inside, the slider is slidably connected to the outer wall of the guide rail inside, and a base is fixedly connected to the outer wall of the guide rail.

[0015] As a further description of the above technical solution:

[0016] A support column is fixedly connected to the top of the base, and a support plate is fixedly connected to the top of the support column.

[0017] As a further description of the above technical solution:

[0018] A motor is fixedly connected to the top of the support plate, and a rotating rod is fixedly connected to the output end of the motor.

[0031] 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.

[0032] Reference Figures 1-4This utility model provides an embodiment of a sheet slitting machine, including a support 1. The support 1 serves as the basic load-bearing structure of the entire machine, providing stable support for the internal components. An unwinding shaft 3 is rotatably connected inside the support 1. The unwinding shaft 3 can rotate flexibly, and a roll of material 2 is provided outside the unwinding shaft 3 to facilitate the smooth unwinding of the roll of material 2. A quick-change blade assembly is fixedly connected inside the support 1. The quick-change blade assembly can quickly replace the appropriate blade 17 according to different materials of the roll of material 2, greatly reducing the downtime caused by blade replacement and improving equipment utilization. A clamping assembly is fixedly connected to the top of the support 1. The clamping assembly can firmly fix the roll of material 2 during transportation through mechanical clamping plates 15 to prevent it from shifting, shaking, or loosening due to inertia and vibration during transportation, ensuring the stability of sheet slitting and the quality of finished products.

[0033] The quick tool changer includes multiple clamping plates 18, which are used to hold the tool holder 16. The clamping plates 18 are fixedly connected inside the bracket 1. Two clamping plates 15 are fixedly connected to the outer wall of the clamping plates 18. A shaft 14 is provided inside the bracket 1. The clamping plates 18 are slidably connected inside the shaft 14. A spring 19 is provided inside the shaft 14. The two clamping plates 15 on the outer wall of the clamping plates 18 cooperate with the shaft 14 and the spring 19 to form an elastic positioning system. The clamping plates 15 are slidably connected inside the shaft 14. Both ends of the spring 19 are fixedly connected to the outer walls of the two clamping plates 15. When the clamping plates 15 and the clamping plates 18 slide, the spring 19 provides buffering and restoring force to ensure that the clamping plates 18 are accurately positioned during tool change and can quickly spring back to their original position. Multiple blade sleeves 16 are slidably connected to the outer wall of the shaft 14, enabling flexible installation and removal of the blade sleeves 16. The outer wall of the clamping plate 18 is slidably connected inside the blade sleeve 16, and the blade 17 is fixedly connected to the outer wall of the blade sleeve 16. When the blade sleeve 16 needs to be replaced, only an external force needs to be applied to the clamping plate 15 to overcome the elastic force of the spring 19, causing the clamping plate 15 to drive the clamping plate 18 to slide inward and disengage. When installing the blade sleeve 16, it is aligned with the clamping plate 18. Under the elastic action of the spring 19, the clamping plate 18 automatically resets and tightly engages with the blade sleeve 16, completing a quick blade change and reducing the downtime of the slitting machine caused by blade changes.

[0034] Reference Figure 5The clamping assembly includes a clamp 5, which slides inward along a guide rail 12 to apply clamping force to the sheet, fix the sheet position, and prevent the sheet from shifting due to tension and cutting force during slitting, thus ensuring slitting dimensional accuracy. The outer wall of the clamp 5 is positioned above the support 1, and a base 4 is fixedly connected to the bottom of the clamp 5. The base 4 serves as the direct bearing platform for the clamp 5, distributing and transmitting the force of the clamp 5 to avoid local stress damage to the support 1. It also provides an installation reference for the slider 13, ensuring the stability of the clamp 5's movement. The slider 13 is fixedly connected to the bottom of the base 4. A guide rail 12 is fixedly connected inside the support 1, and the slider 13 is slidably connected to the outer wall of the guide rail 12. The slider 13 slides along the guide rail 12, ensuring that the clamp 5's movement trajectory is straight. A base 11 is fixedly connected to the outer wall of the guide rail 12, and the base 11 is the bottom layer of the entire assembly. The support, fixed to the bracket 1, provides a stable foundation for the pillar 10 and guide rail 12, ensuring that the upper structure does not wobble under stress. The pillar 10 is fixedly connected to the top of the base 11, and the pillar 10 is vertically connected to the base 11. The support plate 9 is fixedly connected to the top of the pillar 10, and the motor 8 is fixedly connected to the top of the support plate 9. The output end of the motor 8 is fixedly connected to the rotating rod 7. The motor 8 is the power source for the clamping action, converting electrical energy into mechanical energy to drive the rotating rod 7 to rotate, providing power for the opening and closing of the clamp 5. This is existing technology, so it will not be described in detail. Both ends of the rotating rod 7 are rotatably connected to the transmission rod 6. The rotating rod 7 converts the rotational motion of the motor 8 into a synchronous pushing and pulling action on the transmission rod 6. One end of the transmission rod 6 is rotatably connected to the top of the platform 4. Through the lever principle, the rotational motion of the rotating rod 7 is converted into the linear motion of the platform 4 and the clamp 5.

[0035] Working principle: During the cutting process of the roll material 2 by the blade 17, there are two clamping plates 18 inside the shaft 14, connected to the clamping plates 18 by a clamping plate 15. A spring 19 is provided between the two clamping plates 15. When installing the blade 17, the two clamping plates 15 are pressed down, which compresses the spring 19. The clamping plate 18 moves towards the center of the spring 19. At this time, the blade 17 is placed on the blade sleeve 16 with a slot and placed on the shaft 14. After releasing the clamping plate 15, the spring 19 returns to its original state, and the clamping plate 18 moves outward into the slot, fixing the blade 17. This allows for quick replacement of the appropriate blade 17 according to different roll material 2 materials, saving blade changing time and improving production efficiency. Finally, the winding shaft rewinds the cut roll material 2.

[0036] During the unwinding process of the unwinding shaft 3 unwinding the roll 2, the clamping mechanism clamps the roll 2 to maintain its stability. The motor 8 outputs power to the rotating rod 7 to rotate. The rotating rod 7 drives the transmission rod 6 to swing. The transmission rod 6 then drives the platform 4 and the clamp 5 located on it to move horizontally through the guide rail 12 and the slider 13, thereby clamping the conveyed roll 2 so that it will not deviate and cause uneven cutting, thus reducing the scrap rate.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
