Description

Technical Field

[0001] This utility model belongs to the field of gravure printing technology, and specifically relates to a pressing device for a slitting machine. Background Technology

[0002] Traditional gravure printing presses use a pressing device for the material take-up at the die head. However, when this structure is directly used on a slitting machine, the material needs to be divided into segments. During pressing and winding, since the material roll is divided into numerous segments from a single roll, the uneven thickness of the roll affects the neatness of the winding. If some parts of the roll are relatively thin, it will lead to incomplete pressing, resulting in edge bursting and loose winding during the winding process. At the same time, the amount of tension on the roll is also one of the reasons for the uneven thickness of the roll. Because the film is long, it is cut into numerous segments in the final process, and the roll is more easily stretched, resulting in uneven thickness. Utility Model Content

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] Example 1:

[0025] like Figure 1-4 As shown, this embodiment provides a pressing device for a slitting machine, including: two opposing pressing arm support plates 4 slidably connected to a wall panel 1, and a transmission unit disposed on the pressing arm support plates 4; the transmission unit includes a swing arm shaft 11 rotatably connected to the pressing arm support plates 4, traction swing arms 14 and 21 fixedly connected to the swing arm shaft 11, a swing arm roller shaft 13 rotatably connected to the traction swing arms 14 and 21, and a roller 15 disposed on the swing arm roller shaft 13 for pressing the material film; a drive unit disposed on the pressing arm support plates 4 capable of driving the swing arm shaft 11 to rotate; the drive unit includes a traction swing arm cylinder 9, one end of which is rotatably connected to the pressing arm support plates 4 via a cylinder connecting shaft 8, and the other end of which is connected to the swing arm shaft 11 via a connector 10.

[0026] The pressure of the roller 15 on the film is adjusted by the drive unit and transmission unit, so that the film with uneven thickness can be pressed, avoiding problems such as edge bursting and loose winding, and improving the neatness of winding.

[0027] Preferably, it further includes an auxiliary traction unit disposed on the traction arms 14, 21 to drive the roller 15 to rotate; the auxiliary traction unit includes a motor plate 19 fixedly connected to the traction arms 14, 21, a motor 20 disposed on the motor plate 19, a first synchronous pulley 18 connected to the output shaft of the motor 20, a second synchronous pulley 16 connected to the end of the roller 15, and a synchronous belt 17 connecting the first synchronous pulley 18 and the second synchronous pulley 16.

[0028] The auxiliary traction unit can help increase the tension of the film, avoid excessive winding tension which would cause the film to be stretched and have uneven thickness, avoid edge bursting and loose winding, and improve the neatness of winding.

[0029] Preferably, it also includes a lifting cylinder 6 provided on the wall panel 1 and connected to the pressure arm support plate 4; a slider 3 is connected to the side of the pressure arm support plate 4 near the wall panel 1, and the slider 3 can slide up and down along the guide rail 2 provided on the wall panel 1 under the traction of the lifting cylinder 6.

[0030] The lifting structure allows for adjustment of the space of the pressing device to adapt to different working needs.

[0031] Preferably, it further includes a pressure arm positioning shaft 25 rotatably connected to the pressure arm support plate 4, a pressure arm support member 27 fixedly connected to the pressure arm positioning shaft 25 for supporting the rotatable pressure roller 33 from both ends; a pressure arm cylinder 24 disposed on the pressure arm support plate 4 for pulling the pressure arm support member 27 to rotate around the pressure arm positioning shaft 25; the pressure arm cylinder 24 is connected to the pressure arm support plate 4 through a pressure arm connector 23.

[0032] This allows the pressure roller 33 to adjust its contact with the material film in the vertical direction via the pressure arm cylinder 24.

[0033] Preferably, the device further includes an adjustment unit for adjusting the movement of the pressure roller 33 at the end of the pressure arm support 27. This allows the adjustment unit to adjust the horizontal contact between the pressure roller 33 and the material film. The structure of the adjustment unit is quite common in the art, for example, employing a combination of a handwheel and a pressure bar, and will not be described in detail here.

[0034] Work process:

[0035] The traction arm cylinder 9 pulls the connecting piece 10 to move, thereby driving the swing arm shaft 11 to rotate, which in turn drives the traction swing arms 14 and 21 to rotate, thereby driving the roller 15 that presses the film to move.

[0036] The rotation of motor 20 is transmitted to the swing arm roller shaft 13 through the first synchronous pulley 18, the synchronous belt 17, and the second synchronous pulley 16, thereby driving the roller 15 to rotate to assist in the traction of the pressed film.

[0037] When it is necessary to change the working space of the pressing device, the lifting cylinder 6 moves, thereby driving the pressing arm support plate 4 to slide up and down along the guide rail 2 via the slider 3.

[0038] Start the pressure arm cylinder 24 to pull the pressure arm support 27 to rotate around the pressure arm positioning shaft 25, thereby driving the material pressing roller 33 to rotate to adjust the pressing of the material film.

[0039] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
