Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting processing, in particular to a die-cutting device. Background Art

[0002] During the die-cutting process, the axial direction of the die-cutting roller is usually perpendicular to the extension direction of the material strip moving path. However, after the material strip is rewound, the tension of the material strip will change. Since the tension of the material strip is one of the important factors affecting the material strip moving path, the extension direction of the material strip moving path will be offset after the material strip is rewound. At this time, the axial direction of the die-cutting roller and the extension direction of the material strip moving path are difficult to maintain a perpendicular state, resulting in poor quality of the products die-cut on the material strip. In the traditional die-cutting process, after the material strip is rewound, the staff needs to readjust the tension of the material strip to achieve deviation correction of the material strip moving path. However, since the staff needs to debug the tension of the material strip every time the material strip is installed, and the debugging time is long, this greatly reduces the working efficiency of the die-cutting device.

[0033] Reference below Figures 1 to 3 A die-cutting device according to an embodiment of the present invention is described in detail.

[0034] refer to Figure 1 According to some embodiments of the present invention, a die-cutting device includes a mounting seat 100, a die-cutting roller 200, a first mounting member 300 and an adjustment structure 400; the first mounting member 300 is rotatably arranged on the mounting seat 100 around a vertical axis; the die-cutting roller 200 is rotatably arranged on the first mounting member 300 around its own axis, and is used to die-cut the material strip; the adjustment structure 400 is arranged on the mounting seat 100, the adjustment structure 400 is connected to the first mounting member 300, and is used to adjust the rotation angle of the first mounting member 300 around the vertical axis.

[0035] In a die-cutting device of this embodiment, when the extension direction of the moving path of the material strip deviates, the first mounting member 300 is adjusted to rotate about the vertical axis by a certain angle through the adjustment structure 400, thereby driving the die-cutting roller 200 to rotate about the vertical axis by a certain angle until the axial direction of the die-cutting roller 200 remains perpendicular to the extension direction of the moving path of the material strip. From the above adjustment process, it can be seen that when the extension direction of the moving path of the material strip deviates, the axial direction of the die-cutting roller 200 can be adjusted through the adjustment structure 400, so that the axial direction of the die-cutting roller 200 and the extension direction of the moving path of the material strip remain perpendicular. There is no need to adjust the tension of the material strip, the adjustment process is simpler and more convenient, and the working efficiency of the die-cutting device can be improved.

[0036] In some embodiments of the present invention, the adjustment structure 400 includes a threaded adjustment member 410 and a fixed block 420. The fixed block 420 is provided on the mounting base 100. The threaded adjustment member 410 is threadedly connected to the fixed block 420 and is rotatably connected to one end of the first mounting member 300 in a preset horizontal direction. The preset horizontal direction is spaced at a certain angle from the axis direction of the die-cutting roller 200. Under the action of an external force, the threaded adjustment member 410 can rotate relative to the mounting base 100 to drive the first mounting member 300 to rotate around the vertical axis. For example, Figure 1 As shown, the preset horizontal direction is the front-to-back direction, the adjustment structure 400 is disposed on the front side of the first mounting member 300, the threaded adjustment member 410 extends in the front-to-back direction, the threaded adjustment member 410 is threadedly connected to the fixing block 420, and the rod portion of the threaded adjustment member 410 is rotatably connected to the front end of the first mounting member 300. It can be understood that by rotating the threaded adjustment member 410 relative to the mounting base 100 so that the threaded adjustment member 410 moves in the front-to-back direction, the threaded adjustment member 410 drives the first mounting member 300 to rotate about the vertical axis, thereby achieving adjustment of the rotation angle of the first mounting member 300 about the vertical axis.

[0037] It is understandable that the adjustment range of the rotation angle of the first mounting member 300 around the vertical axis is relatively small in actual application. Accordingly, when adjusting the rotation angle of the first mounting member 300 around the vertical axis, corresponding adjustment accuracy is also required. The pitch of the thread on the threaded adjustment member 410 is small and the accuracy is high. When the threaded adjustment member 410 rotates, the staff can control the number of turns of the rotating threaded adjustment member 410 and adjust the distance that the threaded adjustment member 410 moves along the preset horizontal direction, thereby realizing the adjustment of the rotation angle of the first mounting member 300 around the vertical axis.

[0038] In some embodiments, the first mounting member 300 is provided with an adjustment structure 400 on two opposite sides in a preset horizontal direction, and the threaded adjustment members 410 of the two adjustment structures 400 are rotatably abutted against the two ends of the first mounting member 300 in the preset horizontal direction. Figure 1 and Figure 2As shown, an adjustment structure 400 is provided on each of the front and rear sides of the first mounting member 300, and the threaded adjustment members 410 of the two adjustment structures 400 are respectively rotatably abutted against the front and rear ends of the first mounting member 300. It is understandable that since the threaded adjustment members 410 of the two adjustment structures 400 are respectively abutted against the front and rear ends of the first mounting member 300, the two threaded adjustment members 410 can cooperate to limit the first mounting member 300 in the front-to-back direction. When the staff needs to rotate the first mounting member 300 around the vertical axis, the staff can respectively screw the two threaded adjustment members 410 so that the two threaded adjustment members 410 can drive the first mounting member 300 to swing forward or backward, thereby adjusting the rotation angle of the first mounting member 300 around the vertical axis.

[0039] refer to Figure 1 and Figure 2 In some embodiments of the present invention, the fixing block 420 is vertically adjustable on the mounting base 100. It is understood that by adjusting the position of the fixing block 420 in the vertical direction, the position of the threaded adjustment member 410 in the same adjustment structure 400 can be adjusted in the vertical direction, so that the threaded adjustment member 410 can be connected to the first mounting member 300.

[0040] refer to Figure 2 and Figure 3 In some embodiments, the adjustment structure 400 further includes a threaded connector 430. The fixing block 420 is provided with a through hole 421. The mounting base 100 is provided with a plurality of first threaded holes 110 spaced apart in the vertical direction. The threaded connector 430 is passed through the through hole 421 and is threadedly connected to the wall of one of the first threaded holes 110. It is understood that since the plurality of first threaded holes 110 are arranged in the vertical direction, the vertical position of the fixing block 420 connected to the threaded connector 430 can be adjusted by selectively threading the threaded connector 430 to the wall of one of the first threaded holes 110.

[0041] refer to Figure 2 and Figure 3In one embodiment, the insertion hole 421 is in the shape of an elongated strip extending in the vertical direction, and the threaded connector 430 is slidably provided in the insertion hole 421 in the vertical direction. It is understandable that when the threaded connector 430 is threadedly connected to the hole wall of one of the first threaded holes 110, the threaded connector 430 is screwed to separate from the fixing block 420. At this time, the fixing block 420 can slide relative to the threaded connector 430. By sliding the fixing block 420, the threaded adjustment member 410 connected to the fixing block 420 can abut against the first mounting member 300. Then, the threaded connector 430 is screwed again to increase the friction between the fixing block 420 and the mounting base 100, thereby achieving locking and fixing of the fixing block 420 in the vertical direction.

[0042] refer to Figure 3 In a further embodiment of the present invention, the through hole 421 is a countersunk hole. It is understood that the through hole 421 is set as a countersunk hole so that the threaded connector 430 does not protrude from the surface of the fixing block 420 when the fixing block 420 is locked.

[0043] refer to Figure 2 In some embodiments, the adjustment structure 400 includes two threaded connectors 430, and the fixing block 420 is provided with two through-holes 421. The two through-holes 421 are located on opposite sides of the threaded adjustment member 410 in the vertical direction. The two threaded connectors 430 are respectively inserted into the two through-holes 421, and the hole spacing between the two through-holes 421 is the same as the hole spacing between any two adjacent first threaded holes 110. It can be understood that because the two through-holes 421 are respectively provided on the upper and lower sides of the threaded adjustment member 410, the two threaded connectors 430 respectively inserted into the two through-holes 421 can make the fixing block 420 more stable on the mounting base 100 when fixing it to the mounting base 100.

[0044] In some embodiments of the present invention, a vertically extending mounting groove 120 is provided on the mounting base 100, and the first mounting member 300 is slidably provided in the mounting groove 120 along the vertical direction. In the preset horizontal direction, an adjustable gap is left between the first mounting member 300 and the groove wall of the mounting groove 120. For example, Figure 1 and Figure 2As shown, the mounting base 100 is provided with a mounting groove 120 extending in the vertical direction. The first mounting member 300 is slidably disposed in the mounting groove 120 in the vertical direction. An adjustable gap exists between the first mounting member 300 and the groove wall of the mounting groove 120 in the front-to-back direction. It can be understood that by sliding the first mounting member 300 in the vertical direction, the vertical position of the first mounting member 300 can be adjusted. Due to the adjustable gap between the first mounting member 300 and the groove wall of the mounting groove 120 in the front-to-back direction, the first mounting member 300 can rotate about the vertical axis in the first mounting groove 120.

[0045] refer to Figure 1 and Figure 2 In some embodiments of the present invention, a locking structure 500, a driven roller 600, and a second mounting member 700 are further included. The second mounting member 700 is disposed in the mounting groove 120 and is located below the first mounting member 300. The driven roller 600 is rotatably disposed on the second mounting member 700 and is used to cooperate with the die-cutting roller 200 to die-cut the material strip. The locking structure 500 is disposed on the mounting base 100 and is connected to the upper end of the first mounting member 300. The locking structure 500 is used to apply a locking force to the first mounting member 300 to keep it close to the second mounting member 700. It is understandable that a worker can use the locking structure 500 to push the first mounting member 300 toward the second mounting member 700 so that the roller surface of the driven roller 600 can be closely attached to the roller surface of the die-cutting roller 200, thereby enabling the driven roller 600 to cooperate with the die-cutting roller 200 to complete the die-cutting of the material strip.

[0046] refer to Figure 1 In some embodiments, the locking structure 500 includes a mounting block 510 and a threaded locking member 520. The mounting block 510 is disposed on the mounting base 100 and is located above the first mounting member 300. The mounting block 510 is provided with a second vertically extending threaded hole. The threaded locking member 520 is threadedly connected to the wall of the second threaded hole and abuts against the upper end of the first mounting member 300. It will be appreciated that securing the threaded connector 430 to the mounting base 100 via the mounting block 510, rather than by slotting the mounting base 100, simplifies the manufacture of the mounting base 100.

[0047] In other embodiments of the present invention, the locking structure 500 includes a mounting block 510, a threaded locking member 520, and a compression spring. The mounting block 510 is disposed on the mounting base 100 and is located above the first mounting member 300. The mounting block 510 is provided with a second vertically extending threaded hole. The threaded locking member 520 is threadedly connected to the wall of the second threaded hole. The threaded locking member 520 is connected to the first mounting member 300 via a compression spring. The compression spring is used to provide an elastic force to maintain the first mounting member 300 in contact with the second mounting member 700. It is understood that the compression spring can provide a downward elastic force to the first mounting member 300, thereby maintaining the first mounting member 300 in contact with the second mounting member 700. By tightening the threaded locking member 520, the compression of the compression spring is increased or decreased, thereby increasing or decreasing the elastic force provided to the first mounting member 300, thereby controlling the pressure between the first mounting member 300 and the second mounting member 700.

[0048] In some other embodiments of the present invention, two mounting seats 100 are provided, each mounting seat 100 is provided with a first mounting member 300, and the two first mounting members 300 are rotatably arranged around the same vertical axis, and the left and right ends of the die-cutting roller 200 are rotatably connected to the two mounting seats 100 around their own axes.

[0049] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
