[0002] In the die-cutting production process, in order to compound multiple film materials together, a compound module is often provided in the die-cutting equipment. In the related art, the compound module includes a first compound roller and a second compound roller arranged in parallel. Before the compound module works, the staff needs to manually pass the various film materials to be compounded between the first compound roller and the second compound roller. Due to the limited space in the die-cutting equipment and the small gap between the first compound roller and the second compound roller, it is inconvenient for the staff to pass the various film materials to be compounded through the gap between the first compound roller and the second compound roller. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the first aspect of the present invention provides a composite module, which allows workers to more conveniently pass each film material to be composited into the gap between the first composite roller and the second composite roller.

[0004] The second aspect of the present invention also provides a die-cutting device.

[0032] Reference below Figures 1 to 3 A composite module according to an embodiment of the first aspect of the present invention is described in detail.

[0033] refer to Figure 1According to a first embodiment of the present invention, a composite module comprises a first mounting seat 100, a first composite roller 200, a mounting frame 300, and a second composite roller 400; the first composite roller 200 is arranged on the first mounting seat 100; the mounting frame 300 is rotatably arranged on the first mounting seat 100 around a preset axis 300a; the extension direction of the preset axis 300a is spaced at a certain angle from the extension direction of the first composite roller 200; the second composite roller 400 is arranged on the mounting frame 300, and can be moved on the mounting frame 300 0 is driven to the working position, or is driven by the mounting frame 300 to rotate out of the working position; wherein, when the second composite roller 400 is located at the working position, the second composite roller 400 is coplanar with the first composite roller 200 and parallel to the first composite roller 200, and can cooperate with the first composite roller 200 to composite the film material; when the second composite roller 400 is out of the working position, the second composite roller 400 is out of the plane with the first composite roller 200, so as to facilitate the film material to be passed between the second composite roller 400 and the first composite roller 200.

[0034] It should be noted that when the composite module is applied to the die-cutting equipment, the second composite roller 400 is coplanar with and parallel to the first composite roller 200, and can cooperate with the first composite roller 200 to composite the film material. In this case, before the composite module composites the film material, the staff needs to pass the various film materials to be composited through the gap between the first composite roller 200 and the second composite roller 400 along the extension direction of the film material moving path. Due to the limited space in the die-cutting equipment, the gap between the first composite roller 200 and the second composite roller 400 is small, and the operation is inconvenient.

[0035] In the composite module of the present application, since the mounting frame 300 is rotatably arranged on the first mounting seat 100 around a preset axis 300a, the first composite roller 200 is arranged on the first mounting seat 100, and the second composite roller 400 is arranged on the mounting frame 300, before the composite module composites the film material, the staff rotates the mounting frame 300 around the preset axis 300a to make the second composite roller 400 disengage from the working position. At this time, the second composite roller 400 is not in the same plane as the first composite roller 200, and the gap between the first composite roller 200 and the second composite roller 400 is increased. The staff can pass each film material to be composited from one side of the axial direction of the first composite roller 200 along the width direction of the film material moving path through the gap between the first composite roller 200 and the second composite roller 400. Then, the staff rotates the mounting frame 300 around the preset axis 300a to make the second composite roller 400 in the working position. At this time, the second composite roller 400 is parallel and coplanar with the first composite roller 200.

[0036] It can be understood that when the composite module of the present application is working, the staff can rotate the mounting frame 300 around the preset axis 300a to increase the gap between the first composite roller 200 and the second composite roller 400, so that the film material can more conveniently pass through the gap between the first composite roller 200 and the second composite roller 400, thereby reducing the operating difficulty of the staff.

[0037] refer to Figure 1 In some embodiments of the present invention, the composite module further includes a second mounting seat 500, one end of the first composite roller 200 is arranged on the first mounting seat 100, the second mounting seat 500 is arranged on the mounting frame 300, and when the mounting frame 300 carries the second composite roller 400 and rotates to the working position, the second mounting seat 500 can be connected to the end of the first composite roller 200 away from the first mounting seat 100 to lock the second composite roller 400 in the working position. It can be understood that the staff rotates the mounting frame 300 to drive the second composite roller 400 to rotate to the working position, and then connects the second mounting seat 500 to the end of the first composite roller 200 away from the first mounting seat 100, thereby locking the second composite roller 400 in the working position, so as to prevent the second composite roller 400 from leaving the working position when the various film materials are composited.

[0038] In some of these embodiments, reference Figure 1 The second mounting seat 500 is slidably disposed on the mounting frame 300 along the axial direction of the second composite roller 400, and a receiving groove 500a is provided on the side of the second mounting seat 500 facing the first mounting seat 100, and the second mounting seat 500 can be sleeved on the end of the first composite roller 200 away from the first mounting seat 100 through the receiving groove 500a.

[0039] It can be understood that by rotating the mounting frame 300 to drive the second composite roller 400 to rotate, when the second composite roller 400 rotates to the working position, there is a certain distance between the second mounting seat 500 and the end of the first composite roller 200 away from the first mounting seat 100, and the staff then slides the second mounting seat 500 along the axial direction of the second composite roller 400 so that the end of the first composite roller 200 away from the first mounting seat 100 is inserted into the accommodating groove 500a of the second mounting seat 500, thereby fixing the second composite roller 400 on the mounting frame 300 in the working position.

[0040] like Figure 1 and Figure 2As shown, in a further embodiment of the present invention, the second mounting seat 500 includes a fixed block 510 and a mounting plate 520, the mounting plate 520 is slidably disposed on the mounting frame 300 along the axial direction of the second composite roller 400, the fixed block 510 is rotatably disposed on the side of the mounting plate 520 facing the first mounting seat 100, and a receiving groove 500a is provided on the side of the fixed block 510 facing the first mounting seat 100, and the fixed block 510 can be sleeved on the end of the first composite roller 200 away from the first mounting seat 100 through the receiving groove 500a.

[0041] In one embodiment of the present invention, the mounting frame 300 includes a connecting rod 310, a screw rod 320 and a rotating rod 330. The rotating rod 330 is rotatably arranged on the first mounting seat 100 around a preset axis 300a. The connecting rod 310 and the screw rod 320 are both arranged on the rotating rod 330 and are both arranged parallel to the second composite roller 400. The second mounting seat 500 is slidably sleeved on the connecting rod 310. A threaded abutment 321 is threadedly sleeved on the screw rod 320. The threaded abutment 321 abuts against the end face of the second mounting seat 500 away from the first mounting seat 100. For example, Figure 1 and Figure 2 As shown, the mounting frame 300 includes a connecting rod 310, a screw rod 320 and a rotating rod 330. The rotating rod 330 is rotatable around a preset axis 300a and is disposed on the first mounting seat 100. The connecting rod 310 and the screw rod 320 are both disposed on the rotating rod 330 and are both disposed parallel to the second composite roller 400. The second mounting seat 500 can be slidably mounted on the connecting rod 310 and the screw rod 320. A threaded abutment 321 is threadedly mounted on the screw rod 320 on a side of the second mounting seat 500 away from the first mounting seat 100, and the threaded abutment 321 abuts against the end face of the second mounting seat 500 facing away from the first mounting seat 100.

[0042] It can be understood that when the second composite roller 400 is located in the working position, the staff slides the second mounting seat 500 so that the groove wall of the accommodating groove 500a of the second mounting seat 500 abuts against the end face of the first composite roller 200 away from the first mounting seat 100, and then screws the threaded abutment 321 so that the threaded abutment 321 abuts against the end face of the second mounting seat 500 away from the first composite roller 200, thereby locking the second mounting seat 500 on the connecting rod 310 to prevent the second mounting seat 500 from being separated from the first composite roller 200 during the composite process of various film materials.

[0043] refer to Figure 1 and Figure 2In some embodiments of the present invention, the mounting frame 300 further includes two connecting structures 340, which are distributed on the connecting rod 310 along the axial direction of the connecting rod 310, and the opposite ends of the second composite roller 400 are respectively connected to the two connecting structures 340. It can be understood that the two connecting structures 340 are connected to the opposite ends of the second composite roller 400, so that the second composite roller 400 is more stable during operation.

[0044] In one embodiment, the connection structure 340 is connected to the connection rod 310 through a threaded connection member; the mounting frame 300 also includes two abutment member groups, which are arranged one by one with the connection structure 340, and the abutment member group includes two abutment members 350, which are threadedly connected to the screw rod 320, and the two abutment members 350 of the same abutment member group abut against two opposite end surfaces of the corresponding connection structure 340. For example, Figure 1 and Figure 2 As shown, the connection structure 340 is connected to the connection rod 310 through a threaded connection member, and the threaded connection member extends along the radial direction of the connection rod 310. The mounting frame 300 also includes two groups of abutment member groups. The screw rod 320 is provided with two connection structures 340. The abutment member groups are arranged one by one corresponding to the connection structures 340. The abutment member groups include two abutment members 350. The abutment members 350 are threadedly connected to the screw rod 320. The two abutment members 350 of the same abutment member group abut against the two opposite end faces of the corresponding connection structure 340. It can be understood that the two connection structures 340 are connected to the connection rod 310 through the threaded connection member, and then the two abutment members 350 abut against the two opposite end faces of the connection structure 340, thereby reducing the shear force of the threaded connection member, so that the connection between the connection structure 340 and the connection rod 310 and the screw rod 320 is more stable.

[0045] refer to Figure 2 and Figure 3In some embodiments of the present invention, the connection structure 340 includes a slider 341, a mounting block 342 and an elastic member 343. The mounting block 342 is connected to the connecting rod 310, the slider 341 is connected to the second composite roller 400, and the opposite ends of the elastic member 343 are respectively connected to the slider 341 and the mounting block 342. The elastic member 343 is used to provide an elastic force for the slider 341 to drive the second composite roller 400 to approach the first composite roller 200. It can be understood that when the second composite roller 400 is in the working position, the film material to be composited is located between the first composite roller 200 and the second composite roller 400. Since the second composite roller 400 is connected to one end of the elastic member 343, the mounting block 342 is connected to the other end of the elastic member 343, and is fixedly connected to the connecting rod 310, when the elastic member 343 is in a compressed state, the elastic member 343 can provide the slider 341 with an elastic force to approach the first composite roller 200, thereby providing the second composite roller 400 with pressure to cooperate with the first composite roller 200 to composite each film material.

[0046] In a further embodiment of the present invention, a slide groove 342 a is provided on the mounting block 342 , and the slider 341 is slidably disposed in the slide groove 342 a along the radial direction of the second composite roller 400 .

[0047] refer to Figure 3 In some embodiments of the present invention, the second composite roller 400 includes a roller core 410, a roller sleeve 420 and a handle 430. The roller sleeve 420 is rotatably mounted on the roller core 410. An eccentric structure 410a is provided at the end of the roller core 410. The roller core 410 is rotatably connected to the slider 341 through the eccentric structure 410a. The handle 430 is connected to the roller core 410. Under the action of external force, the handle 430 can drive the roller core 410 to rotate relative to the slider 341. It can be understood that the staff rotates the handle 430 to drive the roller core 410 to rotate. Since the roller core 410 is rotatably connected to the slider 341 through the eccentric structure 410a, when the roller core 410 rotates, under the action of the eccentric structure 410a, the second composite roller 400 can approach or move away from the first composite roller 200, thereby adjusting the gap between the first composite roller 200 and the second composite roller 400.

[0048] Specifically, the eccentric structure 410a is a semicircular block. In some other embodiments of the present invention, the eccentric structure 410a is a cam.

[0049] like Figure 1 and Figure 2As shown, in some embodiments of the present invention, the first mounting seat 100 includes a locking block 110 and a connecting block 120, the mounting frame 300 is rotatably disposed on the connecting block 120 around a preset axis 300a, the locking block 110 and the connecting block 120 are detachably connected, and an insertion hole 100a is formed between the locking block 110 and the connecting block 120, and one end of the first composite roller 200 is inserted into the insertion hole 100a. It can be understood that since the locking block 110 and the connecting block 120 are detachably connected, when the first composite roller 200 and the first mounting seat 100 are connected, the staff removes the locking block 110 from the connecting block 120, and then places the first composite roller 200 between the locking block 110 and the connecting block 120, and then connects the locking block 110 to the connecting block 120, so that the first composite roller 200 can be inserted into the insertion hole 100a; when the first composite roller 200 is disassembled from the first mounting seat 100, the staff removes the locking block 110 from the connecting block 120, so that the first composite roller 200 can be detached from the first mounting seat 100.

[0050] In a further embodiment of the present invention, the locking block 110 and the connecting block 120 are connected by bolts, and the bolts penetrate the locking block 110 and are threadedly connected to the connecting block 120. It is understandable that when the first composite roller 200 is penetrated in the insertion hole 100a, the staff screws the bolts to make the locking block 110 close to the connecting block 120, the gap between the locking block 110 and the connecting block 120 is reduced, and the aperture of the insertion hole 100a is reduced to adapt to the diameter of the first composite roller 200, thereby locking the first composite roller 200 on the first mounting seat 100.

[0051] The die-cutting device of the second embodiment of the present invention is described below. A die-cutting device of the second embodiment of the present invention includes a composite module of the first embodiment. By using the composite module in the die-cutting device, the staff can more conveniently pass each film material to be composited into the gap between the first composite roller 200 and the second composite roller 400. For example, in one embodiment, the die-cutting device includes a composite module, and the die-cutting device adopts a composite module of the first embodiment. The operator rotates the mounting frame 300 to drive the second composite roller 400 out of the working position, so that the second composite roller 400 and the first composite roller 200 are not on the same plane. At this time, the staff can more conveniently place each film material to be composited between the first composite roller 200 and the second composite roller 400.

[0052] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
