[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-3 As shown, this embodiment is a worktable for an offset printing machine, comprising:

[0031] A worktable assembly, which includes a body 11;

[0032] The workbench assembly also includes a support rod 12 and a cover 13; the support rod 12 is fixed to one side corner of the top of the machine body 11, and the cover 13 is located between opposite ends of the support rod 12 on one side;

[0033] The machine body 11 is used to connect components such as the support rod 12. The support rod 12 is used to connect the cover 13. The cover 13 is used to shield the printing area of ​​the machine body 11 from light.

[0034] The auxiliary support assembly includes a groove 21, a horizontal plate 22, a push plate 23, a spring 24, and a connecting plate 25. The groove 21 is located at the top of the body 11. The horizontal plate 22 is located at the upper two edges of the inner side of the groove 21. The push plates 23 are arranged in a group and are located between opposite ends of the horizontal plates 22. The springs 24 are arranged in a group and are fixed to the bottom of the push plates 23. The connecting plate 25 is fixed to the bottom of the springs 24 and the bottom of the connecting plate 25 is fixedly connected to the bottom of the inside of the groove 21.

[0035] The groove 21 is used to connect the horizontal plate 22, the horizontal plate 22 is used to open the connecting groove 26, the push plate 23 is used to place the paper and the object to be printed, the spring 24 is used to move the push plate 23, and the connecting plate 25 is used to connect the spring 24 and the inside of the groove 21.

[0036] A set of connecting grooves 26 are provided at opposite ends of the horizontal plate 22. A slider 27 is slidably connected to the inside of the connecting groove 26. The opposite ends of the horizontal and vertical adjacent sliders 27 are fixedly connected to both ends of the push plate 23.

[0037] The connecting groove 26 is used for the connection and movement of the slider 27. The slider 27 is used for the connection between the two ends of the push plate 23 and the connecting groove 26. When the push plate 23 moves by the spring 24, the pushing force pushes the slider 27 to move in the connecting groove 26 through the push plate 23, so that the push plate 23 moves along the direction of the connecting groove 26, thereby preventing the position of the push plate 23 from shifting during the movement.

[0038] Extension plates 28 are fixedly connected to the lower ends of push plate 23, and extension plates 28 are in contact with the bottom surface of horizontal plate 22;

[0039] A magnetic block 29 is fixedly connected to the bonding surface of the extension plate 28, and an adsorption block 291 is fixedly connected to the bottom end of the horizontal plate 22. The magnetic block 29 and the adsorption block 291 are attracted to each other.

[0040] The extension plate 28 is used to limit the push plate 23 when it moves upward. When the push plate 23 moves upward by the spring 24, the extension plate 28 is in contact with the bottom surface of the horizontal plate 22, which causes the magnetic block 29 to be attracted to the adsorption block 291, thereby limiting the push plate 23 after it moves upward.

[0041] Working principle: When the component is not in use, the extension plate 28 and the bottom surface of the horizontal plate 22 are in contact, and the magnetic block 29 and the adsorption block 291 are in contact. When the component is in use, paper or other objects to be printed are placed on the top of the push plate 23, and then the printing tool prints on it. The printing force squeezes the spring 24 through the push plate 23, and the printing force pushes the slider 27 to move in the connecting groove 26, causing the push plate 23 to move down through the spring 24 and the slider 27. At this time, the part with uniform force will be printed normally. The part with uneven force is not squeezed enough by the spring 24, causing the push plate 23 with uneven force to move up through the spring 24, so that the push plate 23 is squeezed against the printing surface of the printing tool, thereby achieving uniform and constant printing pressure.

[0042] The above steps prevent uneven ink coverage and large color differences in printed materials.

[0043] Please see Figure 1 , Figures 3-4 As shown, this embodiment, based on the above embodiment, further includes:

[0044] Connection components;

[0045] The connecting assembly includes a plug groove 31, a plug block 32, and a fixing plate 33. The plug groove 31 is opened at the upper edge of both ends of the inner side of the groove 21. The plug blocks 32 are arranged in two sets and are fixed to opposite ends of the horizontal plate 22 respectively. The plug blocks 32 are engaged with the plug groove 31. The fixing plate 33 is fixed to the top of the plug block 32.

[0046] The insertion slot 31 is used for the insertion of the insertion block 32, the insertion block 32 is used for the connection between the horizontal plate 22 and the machine body 11, and the fixing plate 33 is used for the connection of the limiting rod 35.

[0047] One side of the fixing plate 33 is attached to the top of the body 11, and a limit rod 35 passes through the joint between the two;

[0048] The body 11 has a limit groove 34 at the point where it passes through the limit rod 35, and the limit groove 34 is threadedly connected to the limit rod 35.

[0049] The limiting rod 35 is used to limit the fixed plate 33 and the plug-in block 32 after they are inserted. The limiting groove 34 is used for the insertion and rotation of the limiting rod 35. When the plug-in block 32 is inserted into the plug-in groove 31, the fixed plate 33 is attached to the top of the machine body 11. Then the limiting rod 35 is rotated and inserted into the attachment point between the fixed plate 33 and the machine body 11, thereby limiting the horizontal plate 22.

[0050] Working principle: When the component is not in use, the plug block 32 is not inserted into the plug slot 31. When the component is in use, hold the horizontal plate 22 by hand and insert the plug block 32 into the plug slot 31 so that the fixing plate 33 is in contact with the top of the machine body 11. The limiting rod 35 is threaded through the connection between the fixing plate 33 and the machine body 11, so that the limiting rod 35 is inserted into the limiting groove 34. Rotate the limiting rod 35 so that the limiting rod 35 is rotatably connected to the limiting groove 34 through the thread, thereby limiting the horizontal plate 22 after insertion. At the same time, it is convenient for the staff to disassemble the horizontal plate 22 and maintain the inside of the groove 21.

[0051] The above steps can improve its functionality.

[0052] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
