Description

Technical Field

[0001] This application relates to the field of ink proofing machine technology, and more particularly to a replaceable gravure printing proofing machine. Background Technology

[0002] After the ink is prepared, it is applied using a gravure ink proofing machine onto a color display board to observe the coloring effect. After applying the ink, the color display board needs to be cleaned. However, current color display boards are typically secured to the pressure strip using fastening bolts, making them difficult to disassemble and reassemble. Utility Model Content

[0003] To address the aforementioned issues, this technical solution provides a replaceable gravure printing proofing machine.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A replaceable gravure printing proofing machine, including

[0006] A printing table with a color display board on it;

[0007] Pressure strips are respectively disposed on both sides of the printing table and are used to press the color display board firmly onto the printing table;

[0008] A fast-pressing mechanism includes a linkage rod passing through the pressure bar and the printing table, a pivot hinged to the linkage rod, and a handle provided on the pivot.

[0009] When the rotating shaft rotates to the clamping position, it drives the linkage rod to descend, causing the pressure bar to press down towards the printing table and clamp the color display plate; when the rotating shaft rotates in the opposite direction to the releasing position, it drives the linkage rod to rise, causing the pressure bar to rise away from the printing table and release the clamping of the color display plate.

[0010] As described above, in a replaceable gravure printing proofing machine, the fast pressing mechanism further includes a clamping spring disposed between the pressure bar and the printing table, the clamping spring causing the pressure bar to have a tendency to move away from the printing table.

[0011] As described above, in a replaceable gravure printing proofing machine, the pressure bar includes an inner support leg and an outer support leg, a middle part connecting the inner support leg and the outer support leg, and a cavity disposed between the inner support leg and the outer support leg. The compression spring is located in the cavity and is sleeved on the linkage rod.

[0012] As described above, in a replaceable gravure printing proofing machine, the linkage rod is provided with a first through hole, the rotating shaft is provided with a second through hole, and the fast pressing mechanism further includes a central shaft passing through the first through hole and the second through hole.

[0013] As described above, in a replaceable gravure printing proofing machine, the rotating shaft is provided with a positioning plane and an arc-shaped surface. When the rotating shaft is rotated to the pressing position, the positioning plane abuts against the bottom of the printing table, and the pressure strip is in a pressed state. When the rotating shaft is rotated to the relaxing position, the arc-shaped surface abuts against the bottom of the printing table, and the pressure strip is in a relaxed state.

[0014] As described above, in a replaceable gravure printing proofing machine, the rotation angle range of the rotating shaft is ninety degrees.

[0015] In the replaceable gravure printing proofing machine described above, the distance from the arc-shaped surface to the axis of the rotating shaft is less than the distance from the positioning plane to the axis of the rotating shaft.

[0016] As described above, in a replaceable gravure printing proofing machine, the bottom of the printing table is provided with a positioning hole, and a return spring is provided between the handle and the rotating shaft. When the rotating shaft rotates to the pressing position, the return spring drives the handle to insert into the positioning hole.

[0017] The beneficial effects of this application are:

[0018] This utility model provides a replaceable gravure printing proofing machine. By using a fast-pressing mechanism and turning the handle, the rotating shaft is rotated, thereby pressing and releasing the pressure strip, which in turn presses or releases the color plate, making it easy to assemble and disassemble the color plate.

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] A replaceable gravure printing proofing machine, including

[0026] Printing table 1, on which a color display board 2 is provided;

[0027] Pressure strips 3 are respectively disposed on both sides of the printing table 1 and are used to press the color display board 2 onto the printing table 1;

[0028] The fast pressing mechanism 4 includes a linkage rod 41 passing through the pressure bar 3 and the printing table 1, a rotating shaft 42 hinged to the linkage rod 41, and a handle 43 provided on the rotating shaft 42.

[0029] When the rotating shaft 42 rotates to the pressing position, it drives the linkage rod 41 to descend, causing the pressure strip 3 to press down towards the printing table 1 and press the color display plate 2. When the rotating shaft 42 rotates in the opposite direction to the releasing position, it drives the linkage rod 41 to rise, causing the pressure strip 3 to rise away from the printing table 1 and release the clamping on the color display plate 2.

[0030] This utility model provides a replaceable gravure printing proofing machine. By using a fast-pressing mechanism and turning the handle, the rotating shaft is rotated, thereby pressing and releasing the pressure strip, which in turn presses or releases the color plate, making it easy to assemble and disassemble the color plate.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the fast-pressing mechanism 4 also includes a compression spring 44 disposed between the pressure strip 3 and the printing table 1. The compression spring 44 causes the pressure strip 3 to tend to move away from the printing table 1. The compression spring 44 provides the pressure strip 3 with an elastic force for automatic upward reset. When the rotating shaft 42 rotates to the relaxed position, the spring force assists the pressure strip 3 to be lifted quickly and reliably, ensuring that the color display plate 2 can be smoothly released and removed.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the pressure strip 3 includes an inner support leg 31 and an outer support leg 32, a middle portion 33 connecting the inner support leg 31 and the outer support leg 32, and a cavity 34 disposed between the inner support leg 31 and the outer support leg 32. The compression spring 44 is located in the cavity 34 and is sleeved on the linkage rod 41. The cavity provides downward pressure space for the middle portion, providing greater downward pressure. The "U"-shaped structure (inner support leg 31, outer support leg 32, middle portion 33) and cavity 34 design of the pressure strip 3 provide ideal housing space and protection for the compression spring 44, while allowing the spring force to be more concentrated on the edge of the display plate 2 through the middle portion 33, improving the pressing effect and downward pressure.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the linkage rod 41 is provided with a first through hole 411, the rotating shaft 42 is provided with a second through hole 421, and the fast-pressing mechanism 4 further includes a central shaft 45 passing through the first through hole 411 and the second through hole 421. The central shaft 45 passes through the first through hole 411 of the linkage rod 41 and the second through hole 421 of the rotating shaft 42 to form a hinge, resulting in a simple and reliable structure that ensures the rotating shaft 42 can smoothly and stably drive the linkage rod 41 up and down to transmit the pressing force when rotating.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the rotating shaft 42 is provided with a positioning plane 422 and an arc-shaped surface 423. When the rotating shaft 42 rotates to the pressing position, the positioning plane 422 abuts against the bottom of the printing table 1, and the pressure strip 3 is in a pressed state; when the rotating shaft 42 rotates to the relaxed position, the arc-shaped surface 423 abuts against the bottom of the printing table 1, and the pressure strip 3 is in a relaxed state. The design of the positioning plane 422 and the arc-shaped surface 423 on the rotating shaft 42 utilizes planar contact to achieve a stable and self-locking pressing state, and utilizes arc-shaped contact to form a support gap to achieve a relaxed state. The structure is ingenious, the pressing state is reliably locked, and the relaxed state is clear and unambiguous.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the rotation angle range of the rotating shaft 42 is ninety degrees. By limiting the rotation range of the rotating shaft 42 to 90 degrees (from the pressing position to the releasing position), the operating handle 43 only needs to be rotated a quarter turn, resulting in a shorter stroke and faster, less strenuous operation.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the distance from the arcuate surface 423 to the axis of the rotating shaft 42 is less than the distance from the positioning plane 422 to the axis of the rotating shaft 42. The radius of the arcuate surface 423 is smaller than the radius of the positioning plane 422, ensuring that in the relaxed position, the overall position of the rotating shaft 42 is higher than the bottom of the printing table 1, providing sufficient space for the lifting of the linkage rod 41 and the pressure strip 3, and assisting the spring 44 to achieve more complete relaxation.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the printing table 1 is provided with a positioning hole 11 at its bottom, and a return spring 12 is provided between the handle 43 and the rotating shaft 42. When the rotating shaft 42 rotates to the pressing position, the return spring 12 drives the handle 43 to insert into the positioning hole 11. The positioning hole 11 and the return spring 12 cooperate to automatically spring the handle 43 into the positioning hole and lock it in place when the rotating shaft 42 reaches the pressing position. This effectively prevents the handle 43 from rotating or the rotating shaft 42 from loosening due to vibration or accidental contact during the proofing process, thereby preventing the pressure strip 3 from being accidentally released, ensuring the stability and safety of the pressing state.

[0038] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
