Description

Technical Field

[0001] This utility model relates to the field of printing machinery, and in particular to an imprinting device with a textured coating head and a standby steel roller. Background Technology

[0002] Anilox rollers are the core component of flexographic printing presses. They are mainly used to evenly transfer a certain amount of ink onto the printing plate to print various patterns on the printed matter.

[0003] In conventional printing equipment, ink is applied to the anilox roller and then pressed onto the printing plate to form the desired pattern on the printed material. However, for the pressing of the anilox roller, usually only a single rubber roller is used to press the anilox roller. But for printed materials with high pattern quality requirements, the rubber roller itself has a certain elasticity, which causes uneven pressure on the anilox roller, resulting in a blurry and unclear pattern on the printed material. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides an imprinting device with a textured coating head and a standby steel roller that can improve the pressure uniformity during imprinting.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an imprinting device with a textured coating head and a standby steel roller, which is set between two wall panels of a coating machine that are set apart from each other. Linear guide rails are respectively installed on the inner side of the wall panels. Upper shaft seats and lower shaft seats that are set apart from each other are slidably arranged on the linear guide rails. A steel roller is rotatably installed between the upper shaft seats, and an imprinting rubber roller is rotatably installed between the lower shaft seats. A connecting plate is fixed to the front side of the upper shaft seat. An elongated hole is opened at the lower end of the connecting plate. A suspension screw is connected to the inner side of the front side of the lower shaft seat through the elongated hole. An upwardly extending limiting rack is fixed to the rear side of the lower shaft seat. A locking component is provided between the wall panels to control the movement or stop of the lower shaft seat through the limiting rack.

[0006] Furthermore, a propulsion cylinder is installed on the wall plate above the upper shaft seat, and the piston rod of the propulsion cylinder is connected to the upper shaft seat.

[0007] Specifically, the locking assembly includes a rotating shaft installed between the wall panels. A limiting gear that meshes with the limiting rack is installed on the rotating shaft corresponding to the position of the limiting rack. A bracket is fixed on the outer side of the right wall panel. A locking gear and a locking gear ring are installed sequentially on the rotating shaft extending out of the right wall panel. A locking cylinder is installed on the bracket to push the locking gear ring to slide on the rotating shaft, thereby enabling the locking gear ring to engage with or disengage from the locking gear.

[0008] Furthermore, in order to control the stroke of the propulsion cylinder, a limiting swing rod is fitted on the shaft between the locking gear and the right side wall plate. The limiting swing rod is axially fixed to the side of the locking gear, and limiting posts that control the back-and-forth swing position of the limiting swing rod are fixed on the right side wall plate symmetrical to the central axis of the locking gear.

[0009] The beneficial effects of this utility model are as follows: By setting a steel roller above the printing roller, when it is necessary to increase the printing force of the printing roller, the steel roller can be moved downward to press against the printing roller, thereby achieving the effect of applying pressure to the printing roller, thus improving the uniformity of pressure during printing and ensuring the clarity of the printed pattern.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] like Figures 1-3 The illustrated imprinting device for a textured coating head with a standby steel roller is located between two wall panels 1 spaced apart on the left and right sides of a coating machine. Linear guide rails 2 are respectively installed on the inner side of the wall panels 1. Upper shaft seats 3 and lower shaft seats 4, which are spaced apart vertically, are slidably mounted on the linear guide rails 2. A steel roller 5 is rotatably mounted between the upper shaft seats 3, and an imprinting roller 6 is rotatably mounted between the lower shaft seats 4. A propulsion cylinder 10 is installed on the wall panel 1 above the upper shaft seats 3, and the piston rod of the propulsion cylinder 10 is connected to the upper shaft seats 3.

[0017] A connecting plate 7 is fixed to the front side of the upper shaft seat 3. A long waist hole 7-1 is opened at the lower end of the connecting plate 7. A suspension screw 8 is connected to the inner side of the front side of the lower shaft seat 4 through the long waist hole 7. An upwardly extending limiting rack 9 is fixed to the rear side of the lower shaft seat 4. A locking assembly is provided between the wall panels 2 to control the movement or stop of the lower shaft seat 4 through the limiting rack 9.

[0018] Figure 3 As shown, the locking assembly includes a rotating shaft 11 installed between the wall panels 1. A limiting gear 12, which meshes with the limiting rack 9, is installed on the rotating shaft 11 corresponding to the position of the limiting rack 9. A bracket 13 is fixed on the outer side of the right wall panel 1. A locking gear 14 and a locking gear ring 15 are sequentially installed on the rotating shaft 11 extending out of the right wall panel 1. A locking cylinder 16 is installed on the bracket 13. The piston rod of the locking cylinder 16 is fixedly connected to the right end of the locking gear ring 15. The locking cylinder 16 pushes the locking gear ring 15 to slide on the rotating shaft 11. When the locking gear ring 15 moves to the left to mesh with the locking gear 14, the limiting gear 12 and the limiting rack 9 are locked. When the locking gear ring 15 moves to the right to disengage from the locking gear 14, the limiting gear 12 and the limiting rack 9 are unlocked.

[0019] To control the stroke of the propulsion cylinder 10, a limiting swing rod 17 is fitted on the rotating shaft 11 between the locking gear 14 and the right side wall plate 1. The limiting swing rod 17 is axially fixed to the side of the locking gear 14. On the right side wall plate 1, which is symmetrical to the central axis of the locking gear 14, limiting posts 18 are fixed to control the back-and-forth swing position of the limiting swing rod 17.

[0020] It should be noted that, in the above Figure 1 The locking assembly shown in the diagram is an unfolded view, and its installation position is located on the rear side of the upper shaft seat 3 and the lower shaft seat 4.

[0021] The locking cylinder 16 pushes the locking gear ring 15 to the left to mesh with the locking gear 14, the limiting gear 12 cannot rotate, the limiting rack 9 is locked, and the lower shaft seat 4 is supported on the linear guide rail 2 through the meshing between the limiting rack 9 and the limiting gear 12.

[0022] If it is necessary to increase the pressure of the printing roller 6, the push cylinder 10 is activated, pushing the upper shaft seat 3 downward. The locking cylinder 16 pulls the locking gear ring 15 to the right to disengage from the locking gear 14, unlocking the limiting rack 9. As the upper shaft seat 3 moves up and down on the linear guide rail 2, the suspension screw 8 moves relative to the long waist hole 7-1 until it is in close contact with the upper end of the long waist hole 7-1, pushing the lower shaft seat 4 downward synchronously. When the limiting gear 12 meshes with the limiting rack 9 and rotates, it drives the limiting swing rod 17 to swing forward. When the limiting swing rod 17 contacts the front limiting post 18, the push cylinder 10 stops, and the limiting rack 9 returns to the locked state to support the lower shaft seat 4. At this time, the steel roller 5 presses on the printing roller 6 to increase the printing force of the printing roller 6.

[0023] To move the steel roller 5 upwards and away from the printing roller 6, the push cylinder 10 is activated to pull the upper shaft seat 3 upwards. At the same time, the limit rack 9 is unlocked again. During the upward movement of the upper shaft seat 3, when the suspension screw 8 moves relative to the long waist hole 7-1 to the lower end of the long waist hole 7-1, the limit swing rod 17 contacts the limit post 18 on the rear side, the push cylinder 10 stops, the limit rack 9 is locked, and the steel roller 5 and the printing roller 6 are in a state of vertical separation.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
