Description
Technical Field
[0001] This utility model relates to the field of material label processing, and in particular to a horizontally arranged horizontal die-cutting machine unit. Background Technology
[0002] Currently, in the material label processing industry, it is common practice to install two die-cutting units at the back end of the equipment to perform die-cutting on the paper. For example... Figure 1 As shown, most existing die-cutting units are vertical die-cutting units, which apply working pressure to the die-cutting rollers through a vertical pressure device. Due to the weight of the die-cutting rollers themselves, even after the pressure device is released, the pressure of the die-cutting rollers' own weight still exists, making the adjustment of the die-cutting rollers and the paper quite troublesome.
[0003] Furthermore, existing die-cutting machines can only replace die-cutting rollers by using a lifting device installed on the equipment. This process is not only cumbersome and time-consuming, but also poses certain safety risks.
[0004] In addition, existing die-cutting units have a long paper path between the two die-cutting groups due to their independent single-die-cutting layout. This makes the changes in paper tension have a significant impact on the registration between the two die-cutting groups, resulting in poor registration stability between the two die-cutting groups.
[0005] Therefore, it is necessary to improve the existing die-cutting units. Utility Model Content

[0032] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.
[0033] like Figure 1 and Figure 2 As shown, most existing die-cutting units are vertical die-cutting units, applying working pressure to the die-cutting rollers through a vertical pressure device. Due to the weight of the die-cutting rollers themselves, this structure means that even after the pressure device is released, the rollers still bear the weight of the rollers, making adjustments to the rollers and paper cumbersome. Furthermore, when replacing the die-cutting rollers in existing units, the only option is to use a lifting device installed on the equipment. This process is not only cumbersome and time-consuming but also poses certain safety risks. In addition, because existing die-cutting units have an independent single-die-cutting layout, the paper path between the two die-cutting groups is very long. This means that changes in paper tension significantly affect the registration between the two die-cutting groups, resulting in poor registration stability.
[0034] like Figure 3 and Figure 4As shown, this embodiment provides a horizontally arranged die-cutting machine unit, including a frame 1. A front traction assembly 2, a front die-cutting roller group 3, a rear die-cutting roller group 4, and a rear traction assembly 5 are sequentially arranged on the frame 1. The front die-cutting roller group 3 and the rear die-cutting roller group 4 are arranged horizontally side-by-side, with a die-cutting drive roller 6 positioned between them. A front die-cutting pressure device 7 is located on one side of the front die-cutting roller group 3, and a rear die-cutting pressure device 8 is located on one side of the rear die-cutting roller group 4. The die-cutting pressure devices enable horizontal pressure application to the die-cutting rollers.
[0035] The front die-cutting roller group 3 includes a front die-cutting roller lower support 31, a first front die-cutting roller upper support 32, a second front die-cutting roller upper support 33, a front die-cutting roller 34, and a front die-cutting bottom roller 35. The front die-cutting roller lower support 31 is slidably disposed on the frame 1 in the direction of approaching or moving away from the rear die-cutting roller group 4. The first front die-cutting roller upper support 32 and the second front die-cutting roller upper support 33 are slidably disposed on the front die-cutting roller lower support 31 in the direction of moving into or out of the frame 1. The front die-cutting roller 34 is detachably disposed on the first front die-cutting roller upper support 32, and the front die-cutting bottom roller 35 is detachably disposed on the second front die-cutting roller upper support 33. The rear die-cutting roller assembly 4 includes a rear die-cutting roller lower support 41, a first rear die-cutting roller upper support 42, a second rear die-cutting roller upper support 43, a rear die-cutting roller 44, and a rear die-cutting bottom roller 45. The rear die-cutting roller lower support 41 is slidably mounted on the frame 1 along the direction approaching or away from the front die-cutting roller assembly 3. The first and second rear die-cutting roller upper supports 42 and 43 are slidably mounted on the rear die-cutting roller lower support 41 along the direction of moving into or out of the frame 1. The rear die-cutting roller 44 is detachably mounted on the first rear die-cutting roller upper support 42, and the rear die-cutting bottom roller 45 is detachably mounted on the second rear die-cutting roller upper support 43. The arrangement of the upper and lower supports for the die-cutting rollers greatly improves the safety of die-cutting roller replacement and significantly reduces the replacement time.
[0036] In this invention, the horizontally arranged die-cutting configuration enables horizontal movement of the front and rear die-cutting roller groups. Furthermore, the unified layout, where the die-cutting drive roller 6 drives both sets of die-cutting rollers, results in a very short paper path between the front die-cutting roller 34 and the rear die-cutting roller 44. This minimizes the impact of relative registration tension changes between the two sets of die-cutting rollers, leading to highly stable registration between them. Technically, this achieves: a maximum die-cutting width of 550mm; a die-cutting roller repeat circumference range of 342.9mm to 698.5mm; a maximum operating speed of 200 meters per minute; and a registration accuracy of ±0.15mm between the two sets of die-cutting rollers. This significantly simplifies the die-cutting process for material label products, greatly improves product changeover efficiency, and greatly ensures product stability.
[0037] Specifically, a slidable roller changing trolley 9 is provided on one side of the frame 1. The top surface of the roller changing trolley 9 is flush with the top surfaces of the front die-cutting roller lower support 31 and the rear die-cutting roller lower support 41. The first front die-cutting roller upper support 32 or the second front die-cutting roller upper support 33 can be moved horizontally from the top of the front die-cutting roller lower support 31 onto the roller changing trolley 9; the first rear die-cutting roller upper support 42 or the second rear die-cutting roller upper support 43 can be moved horizontally from the top of the rear die-cutting roller lower support 41 onto the roller changing trolley 9. With the assistance of the roller changing trolley 9, operators can easily change different die-cutting rollers on the die-cutting unit, and the die-cutting rollers can be changed quickly and easily by pulling them out.
[0038] Preferably, a control system is provided on the frame 1. The control system is electrically connected to the front die-cutting and pressing device 7 and the rear die-cutting and pressing device 8, respectively. The control system controls the front die-cutting and pressing device 7 to pressurize the front die-cutting roller group 3 and controls the rear die-cutting and pressing device 8 to pressurize the rear die-cutting roller group 4. This makes the operation of the die-cutting machine more automated and facilitates better operation by the staff.
[0039] Furthermore, both the front die-cutting pressurizing device 7 and the rear die-cutting pressurizing device 8 include a hydraulic system and a piston rod 12 connected to the hydraulic system. A pulley 11 is provided on the other side of the piston rod 12 for tangential movement with the front die-cutting roller group 3 or the rear die-cutting roller group 4. This structural design of the die-cutting pressurizing device allows the pulley 11 to move more flexibly.
[0040] Furthermore, a front support rail 13 and a rear support rail 14 are respectively provided on both sides of the frame 1. The two sides of the front die-cutting roller lower support 31 are slidably connected to the front support rail 13, and the two sides of the rear die-cutting roller lower support 41 are slidably connected to the rear support rail 14. On the one hand, high-precision, heavy-duty linear guides are used for the horizontal movement of the die-cutting roller and the die-cutting bottom roller to ensure load-bearing capacity and movement accuracy. On the other hand, under the action of the front support rail, the working pressure between the die-cutting roller and the die-cutting bottom roller can be easily released after the die-cutting pressure device is released, facilitating some adjustments to the die-cutting roller or paper.
[0041] like Figure 5 and Figure 6As shown, the front die-cutting roller 34, the front die-cutting bottom roller 35, the rear die-cutting roller 44, and the rear die-cutting bottom roller 45 are arranged horizontally and perform die-cutting pressure work together through the front die-cutting pressure device 7 and the rear die-cutting pressure device 8, which are controlled by a hydraulic system. When the front die-cutting pressure device 7 and the rear die-cutting pressure device 8 are released simultaneously, the front die-cutting roller 34, the front die-cutting bottom roller 35, the rear die-cutting roller 44, and the rear die-cutting bottom roller 45 can easily move horizontally along the die-cutting roller support on the front support transfer rail 13 and the rear support transfer rail 14, thereby releasing the die-cutting pressure. This easily releases the working pressure between the die-cutting roller and the die-cutting bottom roller, facilitating adjustments to the die-cutting roller or the paper.
[0042] When the die-cutting machine unit changes to die-cutting rollers of different sizes, the front support rail 13 and the rear support rail 14 move the die-cutting rollers to a working position where they are close to each other in the horizontal direction, and extend the front die-cutting pressure device 7 and the rear die-cutting pressure device 8 to apply pressure to the die-cutting rollers and start the die-cutting work.
[0043] Furthermore, a front locking device 15 is provided between the lower support 31 and the first upper support 32 of the front die-cutting roller, and between the lower support 31 and the second upper support 33 of the front die-cutting roller. The front locking device 15 includes recesses 151 on both sides of the bottom end of the first upper support 32 or the second upper support 33 of the front die-cutting roller, and a locking plate 152 below the recesses 151. The front locking device 15 also includes a slot 153 on the lower support 31 of the front die-cutting roller that matches the recesses 151. The front locking device 15 allows the lower support 31 and the first upper support 32 of the front die-cutting roller, and the lower support 31 and the second upper support 33 of the front die-cutting roller, to be detachably connected together. By providing a locking device between the upper and lower supports, the requirements for machine operation are met, and the stability of the die-cutting roller in its working position is ensured.
[0044] Preferably, a rear locking device 16 is provided between the lower support 41 of the rear die-cutting roller and the upper support 42 of the first rear die-cutting roller, as well as between the lower support 41 of the rear die-cutting roller and the upper support 43 of the second rear die-cutting roller. The structure of the rear locking device 16 is the same as that of the front locking device 15. This facilitates workers in using the same replacement method for different die-cutting rollers, improving work efficiency.
[0045] In addition, a waste removal device 10 is provided on the top of the frame 1, which is used to process paper waste.
[0046] Furthermore, the waste removal device 10 includes a waste removal conveying roller 101 and a paper pressing roller 102 positioned directly above the die-cutting drive roller 6, and a waste rolling roller 103 positioned above and behind the paper pressing roller 102. The waste rolling roller 103 has a recycling chamber 104 below it for recycling waste materials. This facilitates the unified processing of waste materials and helps maintain a clean working area.
[0047] like Figures 7 to 9 As shown, the process of transferring the die-cutting roller and the die-cutting bottom roller is demonstrated by taking the transfer of the front die-cutting roller 34 as an example. In the figure, 34(1) represents the original front die-cutting roller 34 installed on the frame 1, and 34(2) represents the new front die-cutting roller 34 newly installed on the frame 1.
[0048] Figure 7 The position of the front die-cutting roller 34(1) in the working state is shown.
[0049] Figure 8 The demonstration showed that when the staff were changing the front die-cutting roller 34, they first released the front locking device 15, and then pulled out the front die-cutting roller 34 (1) and the first front die-cutting roller support 32 together by pulling them out and placing them on the roller changing trolley 9.
[0050] Figure 9 The demonstration showed that after the staff installed the front die-cutting roller 34(2) onto the first front die-cutting roller upper support 32, they could easily push the front die-cutting roller 34(2) and the first front die-cutting roller upper support 32 together into the front die-cutting roller lower support 31, and then re-fix the front locking device 15 to complete the replacement of the front die-cutting roller 34.
[0051] The transfer and replacement of other die-cutting rollers and die-cutting bottom rollers should be carried out in accordance with the above methods.
[0052] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
