Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, and particularly refers to a pressing device for a die-cutting machine. Background Art

[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. 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. In order to make the workpieces fit the rollers and keep the workpieces flat, pressing parts are provided. Secondly, the pressing parts are driven by hydraulic cylinders, but the hydraulic cylinders require a matching oil source. Most factories have a gas source but few have an oil source, so additional adaptation is required, resulting in relatively high costs. Secondly, the connection between the hydraulic oil and other components uses pipelines, making the structure relatively complex and messy. Summary of the Invention

[0029] The following further describes in detail the detailed implementation manners of the present utility model with reference to the accompanying drawings.

[0030] As Figures 1-7 shown, a pressing device for a die - cutting machine includes two side plates 1, and a plurality of rollers 2 are arranged between the two side plates 1. A pressing member 4 is arranged on one side of the outermost roller 2. The pressing members 4 are two and are respectively located on one side of both ends of the roller 2. And each pressing member 4 is connected to an electric cylinder 5 on the side far from the roller 2, and the electric cylinder 5 is used to drive the pressing member 4 to move.

[0031] At the same time, the two pressing members 4 are connected by a connecting member 6 to achieve synchronous movement, and each pressing member 4 is provided with a bearing one 41 on the side close to the roller 2.

[0032] Therefore, in the actual use process, by using an electric cylinder 5 instead of a hydraulic cylinder, pipelines and oil sources can be reduced, etc., and thus the structure can be made simple and the cost can be reduced. At the same time, synchronous movement is achieved through the connecting member 6, and through the setting of the bearing one 41, it is more convenient for the workpiece to move, and the rotation of the roller 2 will not affect the pressing member 4.

[0033] Secondly, the two pressing members 4 are respectively located on one side of both ends of the roller 2. Compared with only pressing the middle part, the pressing effect is better.

[0034] Moreover, the number of rollers 2 can be selected according to the actual situation. Five rollers 2 are shown in the drawings, that is, five rollers 2 are sequentially arranged between the two side plates 1, and two pressing members 4 are arranged on the outside of the first and fifth rollers 2.

[0035] As Figure 4As shown in the figure, the structure of the pressing member 4 is as follows: First, the pressing member 4 includes a mounting member 42 and a connecting shaft 43, and the connecting shaft 43 is connected to the electric cylinder 5. Moreover, the mounting member 42 is provided with an opening 44 on the side away from the electric cylinder 5, and two first bearings 41 are arranged in the opening 44.

[0036] The arrangement of the two first bearings 41 increases the pressing area and thus ensures the pressing effect.

[0037] As Figure 4 shown in the figure, the structure of the electric cylinder 5 is as follows: First, a mounting plate 7 is arranged between the two side plates 1, and the electric cylinder 5 is arranged on one side of the mounting plate 7. Moreover, the telescopic rod 51 of the electric cylinder 5 passes through the mounting plate 7 and is thus connected to the pressing member 4.

[0038] As Figures 1-2 and Figures 6-7 shown in the figure, the structure of the roller 2 is as follows: First, the rollers 2 are connected by gears. Moreover, one of the rollers 2 is a driving shaft and is connected to a first driving source 8, and the first driving source 8 is connected to the driving shaft through a coupling 3, and the coupling 3 is made of metal.

[0039] Therefore, in the actual use process, since the coupling 3 is made of metal, it can ensure that the rotations on both sides are synchronous and there is no difference. This is because previously it was a flexible connection, so when rotating, the coupling 3 might be deformed, which would cause a slight difference in the rotations on both sides. Now the coupling 3 is a simple metal tube, that is, a rigid connection, so it can ensure that the rotations on both sides are synchronous and there is no difference.

[0040] Meanwhile, a mounting seat 40 and a housing 30 are sequentially arranged between the first driving source 8 and the driving shaft. Moreover, one side of the mounting seat 40 is provided with an opening for connecting the first driving source 8, and the other side of the mounting seat 40 is provided with a shaft, and the shaft is connected to the driving shaft through the coupling 3. Moreover, the housing 30 is provided with a hole for the user to observe the internal situation.

[0041] Therefore, in the actual use process, the housing 30 is arranged outside the coupling 3 to protect it, and the housing 30 is provided with a hole for the user to observe the internal situation.

[0042] As Figure 5 and Figure 7 shown in the figure, mounting parts 21 and connecting parts 22 are arranged at both ends of each roller 2. Among them, the connecting part 22 is used for connecting to the side plate 1. Moreover, a gear 10 is sleeved outside the mounting part 21 at one end of the roller 2, and second bearings 23 are sleeved outside the connecting parts 22 at both ends of the roller 2. Moreover, the connecting part 22 at one end of the driving shaft is connected to the first driving source 8 through the coupling 3.

[0043] Therefore, during actual use, gear connection is achieved through the setting of gear 10, and after the gear 10 is sleeved, screws are also required for fastening. At the same time, bearings two 23 are sleeved on the outer sides of the joint parts 22, so as to ensure that the rotation of the roller 2 will not affect other components, such as the side plate 1, while achieving the connection.

[0044] Moreover, a connection seat 50 for connecting with the side plate 1 is arranged on the outer side of the bearing two 23 of the drive shaft.

[0045] Such as Figure 2 and Figure 5 As shown, except for the drive shaft, the roller 2 is arranged between the two side plates 1 through the mounting frame 9, and a slider 91 is arranged at the bottom of the mounting frame 9, and a track 20 is correspondingly arranged on the inner wall of the side plate 1 for the slider 91.

[0046] Therefore, during actual use, the position of the roller 2 is adjusted by the movement of the slider 91, so as to ensure the meshing of the gear 10 and the tightness of the meshing.

[0047] Moreover, the drive shaft is generally arranged in the middle, and the mounting frame 9 includes a bottom plate 92 and two connecting plates 93. One of the connecting plates 93 is movable and connected with a drive source two 94, and the drive source two 94 is mainly used for pressing the two connecting plates 93, that is, pressing left and right, so that the roller 2 can be stably located between the two connecting plates 93.

[0048] Secondly, the mounting frame 9 further includes a top plate 95, and a cylinder 96 is arranged at the bottom of the bottom plate 92. Therefore, the pressing between the top plate 95 and the bottom plate 92 is achieved through the cylinder 96, so that the roller 2 can be stably located between the top plate 95 and the bottom plate 92.

[0049] At the same time, the connecting plate 93 includes an upper plate 931 and a lower plate 932, and the joint part 22 of the roller 2 is located between the upper plate 931 and the lower plate 932.

[0050] 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.
