Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically a four-color printing press. Background Technology

[0002] During printing, the printed image is first printed onto the rubber roller from the printing plate, and then transferred from the rubber roller to the paper. Printing presses can be classified into sheet-fed printing presses and roll-fed printing presses according to the paper feeding method; they can be classified into single-color, two-color, four-color and multi-color printing presses according to the number of colors printed in one pass; and they can be classified into small printing presses, six-open, four-open, half-open and full-sheet printing presses according to the maximum paper size they can print.

[0003] An investigation revealed that a Chinese utility model patent discloses a four-color, four-page printing machine with a finishing device (publication number: CN217376750U), comprising: a machine body, a discharge port, a guide plate, a storage box, a positioning groove, a guide rail, a groove, a lead screw, a handwheel, a tapping plate, a spring, a movable plate, and a guide rod; the machine body has a discharge port on its right side; the bottom of the discharge port is fixed to the guide plate by bolts; the storage box is located below the front side of the guide plate and is placed on the top of the right side of the machine body; a positioning groove is formed in the middle of the bottom of the storage box; a guide rail is welded to the top of the right side of the machine body; the guide rail is fitted with the inner side of the positioning groove; two grooves are symmetrically arranged on the left and right sides of the guide rail, and the grooves are formed on the top of the right side of the machine body.

[0004] In the aforementioned patent, the flexible connection between the movable plate and the striking plate is achieved through the elastic force of the spring. This design prevents the striking plate from applying excessive force when striking protruding papers in the paper stack, thereby reducing the possibility of paper edge bending. However, when the protruding paper is located in the lower part of the paper stack, due to the pressure from the paper above, the striking plate may have difficulty striking the paper stack completely neatly, resulting in an unsatisfactory paper stack neatness.

[0005] Therefore, this utility model provides a four-color printing press to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a four-color printing press, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes a work plate 1, a printing machine body 2 fixedly connected to the top of the work plate 1, a tidying box 3 on one side of the printing machine body 2, a transfer frame 16 movably connected inside the tidying box 3, a support block 4 fixedly connected to the top of the work plate 1, a first slide rod 6 fixedly connected to the support block 4, a slider 5 slidably connected to the side surface of the first slide rod 6, one side of the slider 5 fixedly connected to one side of the tidying box 3, a support base 8 fixedly connected to the top of the work plate 1, a first motor 9 fixedly connected to the top of the support base 8, a rotating drum 10 fixedly connected to the output end of the first motor 9, a push plate 13 fixedly connected to one side of the tidying box 3, a moving strip 11 fixedly connected to the side of the push plate 13 away from the tidying box 3, a pin 12 fixedly connected to the inner side of the moving strip 11, a guide rail opened on the side surface of the rotating drum 10, the inner side of the moving strip 11 fitting against the side surface of the rotating drum 10, and the pin 12 inserted into the inside of the guide rail.

[0027] A second motor 25 is fixedly connected to one side of the tidying box 3. A bidirectional threaded rod 19 is fixedly connected to the output end of the second motor 25. The bidirectional threaded rod 19 passes through the tidying box 3. A movable plate 21 is threadedly connected to the side surface of the bidirectional threaded rod 19. A connecting rod 22 is slidably connected to the movable plate 21. A contact plate 23 is fixedly connected to one end of the connecting rod 22. A second spring 24 is sleeved on the side surface of the connecting rod 22. One end of the second spring 24 is fixedly connected to the side of the movable plate 21 near the contact plate 23, and the other end of the second spring 24 is fixedly connected to the side of the contact plate 23 near the connecting rod 22.

[0028] A first spring 7 is fitted on the side surface of the first slide rod 6. One end of the first spring 7 is fixedly connected to one side of the support block 4, and the other end of the first spring 7 is fixedly connected to one side of the slider 5.

[0029] The internal structure of the tidying box 3 is fixedly connected to a second slide bar 20, which passes through the movable plate 21.

[0030] When the first motor 9 is started, the output end of the first motor 9 can directly drive the rotating drum 10 to rotate. The guide rail on the rotating drum 10 is a circular track. The insertion post 12 on the moving bar 11 is located in this track and is in contact with the inner wall of this track. When the rotating drum 10 rotates, the insertion post 12 is squeezed by the inner wall of the circular track, which can force the insertion post 12 to move horizontally back and forth with the moving bar 11. The moving bar 11 is connected to the tidying box 3 through the push plate 13 fixed thereto. Therefore, when the moving bar 11 moves, it can drive the tidying box 3 and the slider 5 to move. When the tidying box 3 and the slider 5 move on the first slide bar 6, they can compress the first spring 7. After the tidying box 3 and the slider 5 are reset, the first spring 7 will also be released. The first spring 7, together with the reciprocating movement of the tidying box 3, forms a shaking effect. This shaking effect can be transmitted to the transfer frame 16, thereby causing the paper stack in the transfer frame 16 to shake.

[0031] When the second motor 25 is started, the output end of the second motor 25 can directly drive the bidirectional threaded rod 19 to rotate. The second slide rod 20 provides a limiting effect for the moving plate 21. Therefore, when the bidirectional threaded rod 19 rotates, the moving plate 21 can move. There are two moving plates 21 on the bidirectional threaded rod 19. Each of the two moving plates 21 is equipped with a contact plate 23. When the bidirectional threaded rod 19 drives the two moving plates 21 to approach the paper stack, the contact plate 23 will make contact with the paper stack first. The contact plate 23 is flexibly connected to the moving plate 21 through the connecting rod 22 and the second spring 24. This setting makes the force of the contact plate 23 when it contacts the paper stack not too harsh, thereby reducing the possibility of bending and curling of the paper edges.

[0032] The paper stack 3 is located at the paper feed of the main body 2 of the printing press. After printing, the paper falls into the transfer frame 16 to form a paper stack. After all the paper in the current batch has been printed, the first motor 9 and the second motor 25 can be started at the same time. At this time, the paper stack in the transfer frame 16 will shake. The shaking can loosen the paper stack slightly. At the same time, the contact plate 23 will gradually approach the paper stack and squeeze the paper stack, pushing the protruding paper back into the paper stack, thereby effectively improving the paper stack neatness.

[0033] Furthermore, in order to improve the stability of the moving strip 11 during movement, such as Figure 1 , Figure 2 and Figure 3 As shown, a slide bar 14 is fixedly connected to the outer side of the moving bar 11, and a limit frame 15 is fixedly connected to one side of the support base 8. A slide groove is provided on the limit frame 15, and the slide bar 14 is inserted into the inside of the slide groove.

[0034] When the moving bar 11 moves horizontally back and forth, the slide bar 14 fixed to it will also slide in the groove on the limit frame 15. The setting of the limit frame 15 and the slide bar 14 provides a limiting effect for the moving bar 11, which effectively improves the stability of the moving bar 11 when it moves.

[0035] In order to improve the stability of the transfer frame 16, such as Figure 2 , Figure 4 and Figure 5 As shown, the bottom of the transfer frame 16 is fixedly connected to a limiting strip 17, and the inside of the tidying box 3 is fixedly connected to a support plate 18. The top of the support plate 18 has a slot, the bottom of the transfer frame 16 fits against the top of the support plate 18, and the limiting strip 17 is inserted into the slot.

[0036] A connecting post 27 is fixedly connected to one side of the transfer frame 16, and a clamping plate 26 is rotatably connected to one side of the tidying box 3. The clamping plate 26 has a slot that matches the connecting post 27.

[0037] The support plate 18 is provided to support the transfer frame 16. After the transfer frame 16 is installed inside the tidying box 3, the clamping plate 26 can be rotated so that the clamping holes on the clamping plate 26 hook the connecting column 27, thereby fixing the transfer frame 16. Combined with the limiting effect of the upper limit bar 17, the stability of the transfer frame 16 is effectively improved.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
