Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a film tension maintaining mechanism for an anilox coating head. Background Art

[0002] The anilox roller is the core component of printing. The material passes through the anilox roller for coating printing. When changing the roll, the pressure roller needs to be separated from the anilox roller. At this time, the pressure roller moves upward, and the film cloth wound between the input roller and the pressure roller will inevitably be loose, making it impossible to achieve online roll change;

[0003] In summary, how to ensure that the membrane cloth is always tensioned on the input roller and the pressure roller when changing the roll has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to ensure that the membrane cloth is always stretched tight on the input roller and the pressure roller when changing the roll;

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The utility model discloses a film tension maintaining mechanism for an anilox coating head, comprising: a frame; an anilox roller, which is arranged on the frame; a pressure roller, which is driven by an actuator to slide on the frame and is suitable for contacting with or separating from the anilox roller; an input roller, which is arranged on one side of the frame through a sliding component; a film cloth, which is wound around the input roller and the pressure roller; and a linkage tensioning component, wherein when the actuator drives the pressure roller to move away from the anilox roller, the linkage tensioning component passively drives the input roller to move linearly, so as to keep the film cloth tensioned on the input roller and the pressure roller;

[0007] In this scheme, when the roll needs to be changed, the pressure roller moves upward and away from the anilox roller under the drive of the actuator. During the upward movement of the pressure roller, the power is transmitted to the input roller under the cooperation of the linkage tensioning assembly, so that the input roller moves outward, so that the spacing between the input roller and the anilox roller will not change significantly, so that the membrane cloth is always tensioned on the input roller and the pressure roller;

[0008] Specifically, during the upward movement of the pressure roller, the input roller moves outward in conjunction with the pressure roller, so that the membrane cloth is always tensioned on the input roller and the pressure roller.

[0009] In order to explain how the pressure roller performs lifting movement, the utility model adopts a lifting slide seat provided on the frame; a lifting slider, which is slidably provided on the lifting slide seat; the input roller, which is provided on the lifting slider;

[0010] The lifting position of the pressure roller can be adjusted by the cooperation of the lifting slide and the lifting block.

[0011] For the specific structure of the sliding component, the present utility model adopts a sliding component including: a horizontal sliding base, which is arranged on the frame; a horizontal sliding block, which is slidably arranged on the horizontal sliding base, and an input roller is arranged thereon.

[0012] Through the cooperation of the horizontal sliding base and the horizontal sliding block, the input roller can be adjusted left and right in the horizontal direction.

[0013] For the specific structure of the actuator, the present utility model adopts the actuator including: a lifting cylinder, whose cylinder body is connected to the frame, and whose movable end is connected to the lifting slider.

[0014] The actuator adopts a lifting cylinder, the cylinder is connected to the lifting slider, and the operation of the cylinder realizes the lifting of the lifting slider.

[0015] For the specific structure of the linkage tensioning component, the present utility model adopts the linkage tensioning component including: a vertical rack, which is connected to one side of the lifting slider; a horizontal rack, which is connected to one side of the horizontal slider; a transmission gear, which is rotatably arranged on the frame and meshes with the vertical rack and the horizontal rack respectively.

[0016] In this solution, the transmission gear is freely rotatably arranged on the frame and meshes with the vertical rack and the horizontal rack; when the lifting cylinder works, it drives the vertical rack to lift, then drives the transmission gear to rotate, thereby realizing the horizontal movement of the horizontal rack, and finally realizing the linear movement of the input roller; that is, when the vertical rack is forced to rise, the transmission gear can rotate counterclockwise, thereby realizing the horizontal outward movement of the horizontal rack and the input roller.

[0017] The beneficial effect of the present utility model: The present utility model is a film tension maintaining mechanism for a gravure coating head. When a roll change is required, the pressure roller moves upward and away from the gravure roll under the drive of the actuator. During the upward movement of the pressure roller, with the cooperation of the linkage tensioning component, the power is transmitted to the input roller, so that the input roller moves outward, so that the distance between the input roller and the gravure roll does not change greatly, and the film is always tensioned on the input roller and the pressure roller.

[0021] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0022] like Figure 1 As shown, the utility model is a film tension maintaining mechanism for an anilox coating head, comprising: a frame 1; an anilox roller 2, which is arranged on the frame 1; a pressure roller 3, which is driven by an actuator to slide on the frame 1, and is suitable for contacting with or separating from the anilox roller 2; an input roller 4, which is arranged on one side of the frame 1 through a sliding component; a film cloth 5, which is wound around the input roller 4 and the pressure roller 3; a linkage tensioning component, when the actuator drives the pressure roller 3 to move away from the anilox roller 2, the linkage tensioning component passively drives the input roller 4 to move linearly, and keeps the film cloth 5 tensioned on the input roller 4 and the pressure roller 3;

[0023] In this scheme, when the roll needs to be changed, the pressure roller moves upward and away from the anilox roller under the drive of the actuator. During the upward movement of the pressure roller, the power is transmitted to the input roller under the cooperation of the linkage tensioning assembly, so that the input roller moves outward, so that the spacing between the input roller and the anilox roller will not change significantly, so that the membrane cloth is always tensioned on the input roller and the pressure roller;

[0024] Specifically, during the upward movement of the pressure roller, the input roller moves outward in conjunction with the pressure roller, so that the membrane cloth is always tensioned on the input roller and the pressure roller.

[0032] In this solution, the transmission gear is freely rotatably arranged on the frame and meshes with the vertical rack and the horizontal rack. When the lifting cylinder works, it drives the vertical rack to lift, then drives the transmission gear to rotate, and further realizes the horizontal movement of the horizontal rack, and finally realizes the linear movement of the input roller. That is, when the vertical rack rises under force, the transmission gear can rotate counterclockwise, and further realizes the horizontal outward movement of the horizontal rack and the input roller.
