Description

Technical Field

[0001] The utility model relates to the technical field, in particular to an imprinting device of a printing press. Background Art

[0002] A pad printer is a highly efficient printing device whose operating principle is primarily based on the transfer of ink and the deformation of a silicone pad. During the printing process, ink is first evenly applied to a pad (also known as a squeegee) using an ink scraper. The pad is then coated with ink, transferring the ink from the recessed areas of the pad to the surface of the silicone pad. At this point, an ink pattern corresponding to the recessed areas of the pad is formed on the surface of the silicone pad. The silicone pad is then mechanically driven to move over the substrate (such as plastic, leather, or metal) and into contact with the surface. The silicone pad's elasticity and deformability allow it to conform to the surface of the substrate, accurately transferring the ink pattern. Finally, through proper drying and curing, the ink pattern is firmly fixed to the surface, creating the final print. Pad printers offer advantages such as high printing speed, high precision, and wide adaptability, making them widely used in various fields.

[0003] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: a connecting structure is provided on the top of the glue head, which is fixed to the moving mechanism of the moving mechanism through the connecting structure, but the connecting structure can only play a connecting role. When the printing position and the required position are slightly offset in one direction during printing, the adaptation effect can only be achieved by adjusting the moving distance of the moving mechanism, but the adjustment distance is relatively large and cannot meet the needs of fine displacement adjustment, which brings inconvenience to use. Utility Model Content

[0004] The main purpose of the utility model is to provide a printing press imprinting device, which can effectively solve the problems in the background technology.

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

[0006] The printing press imprinting device includes a rubber head, a top plate is fixed on the top of the rubber head, half box frames are provided at both ends of the top of the top plate, an adjusting block is inserted between the half box frames, an adjusting column is fixed on the top of the adjusting block, four key grooves are equidistantly chiseled on the outer side of the top of the adjusting column, a screw rod 2 is fixed at the top center position of the adjusting column between the four key grooves, a nut 2 is threadedly connected to the outer wall of the screw rod 2, screw grooves are chiseled on the sides of the half box frames away from each other, hexagonal bolts are threadedly connected to the inside of the screw grooves, and jacks are chiseled on the side walls on both sides of the screw groove of the adjusting block.

[0007] Preferably, the inner thickness of the half box frame matches the thickness of the adjustment block, the distance between the front and rear ends of the adjustment block matches the distance between the front and rear ends of the half box frame, and the adjustment blocks slide inside the half box frame respectively.

[0008] Preferably, one end of the hexagonal bolt passing through the screw groove is respectively inserted into the inside of the socket at the matching position, and the outer dimensions of the hexagonal bolt are respectively matched with the inner dimensions of the socket.

[0009] Preferably, the two ear plates at matching positions are detachably connected via bolt assemblies.

[0010] Preferably, the second screw rod is respectively connected to a through hole of matching size, and the second nut is located at the inner bottom of the U-shaped seat.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

The fine-tuning distance can make it match and return to the correct position when it is slightly offset in one direction, avoiding defective printing.

[0014] 2. The U-shaped seat is welded to the bottom of the base of the moving mechanism. The combination of the U-shaped seat and the auxiliary structure on the adjustment block enables the device to be quickly installed on the moving mechanism. When the adjustment column is rotated ninety degrees, the rubber head can be converted from the X-axis to the Y-axis direction, and the insertion of the spline and the keyway can achieve the effect of limiting the position after the steering adjustment. Subsequently, the screw rod 2 is re-pierced through the hole and threadedly connected to the nut 2 to complete the limit. This technical solution can avoid the problem that the traditional connection structure cannot adjust the axial direction and needs to replace the connection mechanism with different axial directions, which is cumbersome and increases the cost.

A spline 52 is fixed to the bottom of the U-shaped seat 5 at the keyway 43. Ear plates 33 are fixed to the front and rear ends of the half box frame 3 on the side close to each other, and a bolt assembly 35 is provided between the two ear plates 33 at matching positions. Ear plates 2 34 are fixed to the two ends of the half box frame 3 on the side away from each other, and a screw 21 is fixed to the top of the top plate 2 at the position of the ear plate 2 34. The outer wall of the screw 21 is threadedly connected with a nut 22. A matching groove 36 is bored on the top of the half box frame 3 at the position of the adjusting column 42, and the adjusting column 42 is connected to the matching groove 36.

[0022] Specifically, the internal thickness of the half box frame 3 matches the thickness of the adjustment block 4, the spacing length between the front and rear ends of the adjustment block 4 matches the spacing length between the front and rear ends of the half box frame 3, and the adjustment blocks 4 slide inside the half box frame 3 respectively, and one end of the hexagonal bolt 32 passes through the screw groove 31 and is inserted into the socket 41 at the matching position, and the outer dimensions of the hexagonal bolt 32 match the inner dimensions of the socket 41, so that the adjustment movement is more horizontal.

[0023] Specifically, the two ear plates 33 at matching positions are detachably connected via bolt assemblies 35 , so that the adjustment block 4 can be conveniently embedded therein.

[0024] Specifically, the second screw 44 is connected to the through hole 51 of matching size, and the second nut 45 is located at the inner bottom of the U-shaped seat 5, so that the second screw 44 and the U-shaped seat 5 welded to the base of the moving mechanism can be quickly disassembled and assembled.

[0026] Working principle:

[0027] The hexagonal bolts 32 at both ends of the half-box frame 3 are mutually adjusted so that the adjustment block 4 can change the position of the rubber head 1 according to the fine-tuning requirements. The fine-tuning distance can make it match and return it when it is slightly offset in one direction, avoiding the situation of defective printing.

[0028] Adjustment: The hexagonal bolts 32 on the left and right rotate in opposite directions at the same time, and the ends thereof inserted into the sockets 41 can press against the adjustment block 4 to move left and right in the half-box frame 3, thereby changing the direction of the rubber head 1 and completing the stripping work.

[0029] When the adjusting column 42 is rotated ninety degrees, the rubber head 1 can be converted from the X-axis to the Y-axis direction, and the insertion of the spline 52 and the keyway 43 can achieve the effect of limiting the position after the steering adjustment. Then, the screw 2 44 is re-through the through-hole 51 and threadedly connected with the nut 2 45 to complete the limiting. The U-shaped seat 5 is welded to the bottom of the base of the moving mechanism. The combination of the U-shaped seat 5 and the auxiliary mechanism on the adjusting block 4 can enable the device to be quickly installed on the base of the moving mechanism. This technical solution can avoid the problem that the traditional connection structure cannot adjust the axial direction and the need to replace the connection mechanism with different axial directions is cumbersome and cost-increased.
