[0002] A die-cutting machine is one of the most commonly used devices for manufacturing printed products. First, die-cutting knives are combined into a die-cutting plate according to the patterns required by product design, and under the action of pressure, printed products or other circular blanks are rolled and cut into the required shapes or cut marks. Among them, workpieces such as printed products need to be transported, and the transportation is carried out through rollers. Currently, a U-shaped mounting bracket is used for the installation of the roller. However, the upper end of the U-shaped mounting bracket is open, so the stability is not very high. Moreover, the two side plates of the U-shaped mounting bracket are pressed by a hydraulic cylinder, but the hydraulic cylinder requires a matching oil source, and most factories have a gas source but few have an oil source, so additional adaptation is required, and thus the cost is relatively high. Summary of the Invention

[0028] The following further elaborates on the specific embodiments of the present utility model in conjunction with the accompanying drawings.

[0029] As Figures 1-6 shown, an installation structure of a roller includes an installation frame 1 and a roller 2, and the installation frame 1 includes a bottom plate 11 and two connecting plates 12 located on the bottom plate 11, and the tops of the two connecting plates 12 are connected by a top plate 14.

[0030] Therefore, in the actual use process, the U - shape is changed into a rectangle through the setting of the top plate 14, so the stability is increased.

[0031] Meanwhile, the roller 2 is located between the two connecting plates 12, and one of the connecting plates 12 is movable and connected to a first cylinder 13. Therefore, in the actual use process, the first cylinder 13 drives the connected connecting plate 12 to achieve left - right pressing. Thus, the present utility model uses a cylinder instead of a hydraulic cylinder, which can reduce the oil source and further reduce the cost.

[0032] Secondly, the structure of the top plate 14 is as follows: First, connection grooves 141 are opened at the bottoms of both ends of the top plate 14, and the tops of the two connecting plates 12 are located in the connection grooves 141, and the top plate 14 and the connecting plates 12 are connected by fasteners. The fasteners are screws.

[0033] Moreover, a second cylinder 15 is provided on the bottom plate 11, and the second cylinder 15 is used to drive the bottom plate 11 to achieve up - down pressing. Therefore, in the actual use process, the second cylinder 15 drives the connected bottom plate 11 to achieve up - down pressing.

[0034] As Figure 4 shown, the structure of the roller 2 is as follows: First, connection portions 21 are provided at both ends of the roller 2, and the connecting plate 12 includes an upper plate 121 and a lower plate 122, and a first bearing 22 is sleeved outside the connection portion 21 and is located between the upper plate 121 and the lower plate 122.

[0035] Therefore, in the actual use process, the setting of the first bearing 22 avoids the situation that the connecting plate 12 is driven by the roller 2 to rotate synchronously.

[0036] As Figures 1-2 shown, it further includes two side plates 3, and a plurality of rollers 2 are provided between the two side plates 3, and the rollers 2 correspond to the installation frames 1 one by one.

[0037] Meanwhile, a drive shaft 4 is arranged between the two middle rollers 2, and the rollers 2 and between the drive shaft 4 and the rollers 2 are connected by gears. One end of the drive shaft is connected to a drive source 6 through a coupling 5, and the coupling 5 is made of metal.

[0038] Therefore, during actual use, since the coupling 5 is made of metal, it can ensure that the rotations on both sides are synchronous without differences. This is because previously it was a flexible connection, so when rotating, the coupling 5 might deform, thus causing slight differences in the rotations on both sides. Now the coupling 5 is a simple metal tube, that is, a rigid connection, so it can ensure that the rotations on both sides are synchronous without differences.

[0039] The drive shaft is connected to the side plate 1 through a connection seat 60, and a third bearing is arranged between the connection seat 60 and the drive shaft.

[0040] Meanwhile, the gear connection is as follows: First, mounting parts are arranged at both ends of the roller 2 and the drive shaft 4, and gears 8 are sleeved outside the mounting parts. Therefore, during actual use, the gear connection is achieved through the arrangement of the gears 8, and after the gears 8 are sleeved, screws are also required for fastening.

[0041] Moreover, sliders 16 are arranged at the bottom of the bottom plate 11, and tracks 7 are arranged on the inner wall of the side plate 3 corresponding to the sliders 16. Therefore, during actual use, by moving the sliders 16, the position of the roller 2 is adjusted to ensure the tightness and stability of the gear connection, that is, to ensure the meshing of the gears 8 and the tightness of the meshing.

[0042] Meanwhile, a mounting seat 30 and a housing 40 are successively arranged between the drive source 6 and the drive shaft 4. One side of the mounting seat 30 is provided with an opening for connecting the drive source 6. A shaft is arranged on the other side of the mounting seat 30, and the shaft is connected to the drive shaft through the coupling 5. The housing 40 is provided with a hole for the user to view the internal situation.

[0043] Therefore, during actual use, a housing 40 is arranged outside the coupling 5 to protect it, and the housing 40 is provided with a hole for the user to view the internal situation.

[0044] As Figures 1-2 shown, a pressing member 9 is arranged on one side of the outer roller 2. There are two pressing members 9, which are respectively on one side of both ends of the roller 2. And each pressing member 9 is connected to an electric cylinder 10 on the side far from the roller 2, and the electric cylinder 10 is used to drive the pressing member 9 to move. Moreover, the two pressing members 9 are connected through a connecting member 20 to achieve synchronous movement, and a second bearing is arranged on the side of each pressing member 9 close to the roller 2.

[0045] Therefore, in the actual use process, the electric cylinder 10 is used to replace the hydraulic cylinder, so that pipelines, oil sources, etc. can be reduced, and thus the structure can be simplified and the cost can be reduced. At the same time, the synchronous movement is realized through the connecting piece 20, and the movement of the workpiece is more convenient through the setting of the second bearing, and the rotation of the roller 2 will not affect the pressing piece 9.

[0046] At the same time, the electric cylinder 10 is arranged between the two side plates 3 through the mounting plate 50.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. At the same time, the present invention is not limited by the above embodiments. Therefore, without departing from the principles and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
