Description

Technical Field

[0001] The present application relates to the technical field of screen printing mechanisms, and specifically to a four-column screen printing mechanism applicable to a screen printing machine. Background Art

[0002] A screen printing machine, also known as a silk screen printing machine, is a machine that uses a silk screen printing plate for printing and belongs to a type of printing machine. Its main function is to print text and images. A four-column screen printing machine is one type of screen printing machine. When the four-column screen printing machine is working, a sufficient amount of ink is provided above the silk screen. The squeegee moves in a straight line on the silk screen, causing the squeegee to transfer the ink through the silk screen and print it on the surface of the product. Subsequently, the squeegee returns to its original position and scrapes the ink back to its original position on the silk screen. However, during this process, the squeegee will cause wear on the silk screen, resulting in a short service life of the silk screen. Therefore, it is necessary to regularly and frequently replace the silk screen.

[0003] After retrieval, a Chinese patent discloses a screen printing mechanism for a lead-acid battery (authorized publication number CN116890507 A), which includes a silk screen mechanism. The silk screen mechanism includes a silk screen frame, and a silk screen cloth is detachably installed inside the silk screen frame. It is characterized in that it further includes a screen printing mechanism installed above the silk screen cloth. The screen printing mechanism includes a mounting block, on which a first cylinder and a second cylinder are installed in parallel. The extended end of the first cylinder is detachably connected to a doctor blade, and the extended end of the second cylinder is detachably connected to a squeegee. The lower end of the doctor blade inclines towards the squeegee; a linear movement mechanism is connected to the mounting block to drive the screen printing mechanism to perform a linear reciprocating movement;

[0004] Although this patented technology can avoid the contact friction between the squeegee and the silk screen cloth during the return process and reduce wear, the installation of its silk screen frame and silk screen cloth is still the same as that of a traditional four-column screen printing machine, which is completed by tightening multiple screws. When it is necessary to replace the silk screen frame and silk screen cloth, each screw needs to be loosened one by one before it can be disassembled. Such an operation method undoubtedly increases the labor intensity of workers, and at the same time, repeatedly turning the screws is likely to cause the occurrence of thread stripping, which is not conducive to actual application and operation.

[0005] Therefore, those skilled in the art provide a four-column screen printing mechanism applicable to a screen printing machine to solve the problems raised in the above background art. Summary of the Utility Model

[0032] The present application will be further described in detail below with reference to the drawings and embodiments.

[0033] Referring to Figure 1 and Figure 2 , an embodiment of the present application provides a four-column screen printing mechanism applicable to a screen printing machine, including a frame 1. A transverse movement mechanism is arranged inside the frame 1, and a screen printing mechanism is arranged on the transverse movement mechanism. The transverse movement mechanism is used to drive the screen printing mechanism to move transversely, so as to facilitate screen printing operations through the screen printing mechanism.

[0034] Both ends of the frame 1 are equipped with connecting plates 21. At both ends of the bottom of the connecting plate 21, second cylinders 22 are provided. The piston rods of the second cylinders 22 are fixedly connected to the bottom of the connecting plate 21. By using the operation of the second cylinders 22, the overall height position of the frame 1 can be controlled. At the bottom of each of the second cylinders 22, a mounting plate 23 is installed. At the four corners of the top of the mounting plate 23, mounting holes are provided. By using the mounting plate 23 with mounting holes, the device can be installed on a silk screen printing machine for use.

[0035] Four fixing rods 2 are fixed to the bottom of the frame 1. Between the bottoms of the corresponding two fixing rods 2, mounting bars 3 are installed. A screen frame 4 is slidably installed between the two mounting bars 3. A screen cloth 5 is installed inside the screen frame 4. An installation mechanism is provided between the two mounting bars 3 for limiting and fixing the screen frame 4.

[0036] By providing an installation mechanism at the bottom of the frame 1, the traditional screw installation method can be replaced. On the one hand, the installation and disassembly operations of the screen frame 4 and the screen cloth 5 can be realized quickly, without having to screw each screw one by one. This not only reduces the labor intensity of workers, but also improves the installation and disassembly efficiency. On the other hand, it can avoid the occurrence of the phenomenon of thread slipping caused by screwing the screws multiple times, ensuring the service life of the device and being beneficial to practical application and operation.

[0037] Refer to Figure 1 and Figure 2 In one aspect of this embodiment, the lateral movement mechanism includes two grooves 6, a lead screw 7, a slide bar 8, a motor 9 and a cross plate 10. The two grooves 6 are respectively opened on both sides of the inner wall of the frame 1. The lead screw 7 is rotatably connected inside one of the grooves 6, and the slide bar 8 is fixed inside the other groove 6. The motor 9 is installed outside the frame 1, and the output shaft of the motor 9 is fixedly connected to one end of the lead screw 7. By using the operation of the motor 9, the lead screw 7 can be driven to rotate. The cross plate 10 is threadedly connected to the outside of the lead screw 7, and the end of the cross plate 10 away from the lead screw 7 is slidably connected to the slide bar 8. By rotating the lead screw 7, the cross plate 10 threadedly connected thereto can be driven to move laterally inside the frame 1.

[0038] Refer to Figure 3, in one aspect of this embodiment, the silk-screen printing mechanism includes two first cylinders 11, an ink doctor blade 12, a squeegee 13, and four limit rods 14. The two first cylinders 11 are both installed on the top of the cross plate 10, and the piston rods of the first cylinders 11 extend to the bottom of the cross plate 10. The ink doctor blade 12 and the squeegee 13 are respectively fixed on the piston rods of the two first cylinders 11. By the operation of the first cylinders 11, the height positions of the ink doctor blade 12 and the squeegee 13 can be adjusted, so as to perform silk-screen printing operations better. The limit rods 14 are all slidably connected to the top of the cross plate 10 and are located on both sides of the two first cylinders 11. The limit rods 14 can be used to increase the stability of the ink doctor blade 12 and the squeegee 13 when moving up and down.

[0039] Referring to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , in one aspect of this embodiment, the installation mechanism includes two sliding grooves 15, two buffer grooves 16, an unlocking plate 17, two springs 18, two clamping blocks 19, and two clamping grooves 20. The two sliding grooves 15 are respectively opened on one side of the two installation strips 3 close to each other. The screen frame 4 slides between the two sliding grooves 15. The sliding grooves 15 can be used to quickly perform preliminary position limitation on the screen frame 4. The two buffer grooves 16 are respectively opened at one end inside the two installation strips 3. The unlocking plate 17 slides between the tops of the two installation strips 3, and the bottom of the unlocking plate 17 extends into the buffer grooves 16. The springs 18 are fixed between the unlocking plate 17 and the top of the inner wall of the buffer grooves 16. The springs 18 can be used to control the unlocking plate 17 to return to its position inside the buffer grooves 16. The two clamping blocks 19 are respectively installed at both ends of the bottom of the unlocking plate 17. The two clamping grooves 20 are respectively opened at both ends of the top of the screen frame 4. One end of each clamping block 19 extends into the corresponding clamping groove 20. By the clamping blocks 19 entering the clamping grooves 20, the position of the screen frame 4 is fixed, so that it cannot slide out of the sliding grooves 15. A 45-degree inclined surface is provided on one side of each clamping block 19. Due to the effect of the inclined surface, when the screen frame 4 slides and is installed into the sliding grooves 15, it can abut against the clamping blocks 19, causing the unlocking plate 17 to move inside the buffer grooves 16 and compress the springs 18. When the screen frame 4 slides and is installed to the designated position, under the elastic force of the springs 18, the unlocking plate 17 and the clamping blocks 19 can return to their positions, so that the clamping blocks 19 enter the corresponding clamping grooves 20, thus quickly completing the installation operation.

[0040] Working principle:

[0041] When in use, first install the device on the silk-screen printing machine through the mounting plate 23 with mounting holes, and then connect the motor 9, the first cylinders 11, and the second cylinders 22 to the controller on the silk-screen printing machine, so as to facilitate subsequent use control;

[0042] When performing screen printing operations, by controlling the operation of the second cylinder 22, the height position of the frame 1 and the screen frame 4 is adjusted so that the bottom of the screen frame 4 touches the surface of the product to be screen printed. Then, by controlling the motor 9 to operate, the lead screw 7 is driven to rotate. Through the rotation of the lead screw 7, the cross plate 10 threadedly connected thereto is driven to move horizontally inside the frame 1, thereby driving the ink return blade 12 and the squeegee 13 to move horizontally, and using the ink return blade 12 and the squeegee 13 to perform screen printing operations;

[0043] When it is necessary to replace the screen frame 4 and the screen cloth 5, the unlocking plate 17 can be toggled upward, so that its bottom moves upward inside the buffer groove 16 and compresses the spring 18. At the same time, the clamping block 19 is driven to move upward, and the clamping block 19 is disengaged from the inside of the clamping groove 20. At this time, the screen frame 4 is pulled to disengage it from the inside of the sliding groove 15, and the screen frame 4 can be disassembled. Then, the new screen frame 4 and the screen cloth 5 are placed inside the sliding groove 15 and slidably installed. When one end of the screen frame 4 touches the inclined surface outside the clamping block 19, the screen frame 4 is continuously pushed to slide and install. At this time, due to the action of the inclined surface, when the screen frame 4 slides and installs into the inside of the sliding groove 15, it can abut against the clamping block 19, driving the unlocking plate 17 to move inside the buffer groove 16 and compress the spring 18. When the screen frame 4 slides and installs to the designated position, under the elastic force of the spring 18, the unlocking plate 17 and the clamping block 19 can be reset, so that the clamping block 19 enters the corresponding clamping groove 20, thus quickly completing the installation operation;

[0044] By providing an installation mechanism at the bottom of the frame 1, it can replace the traditional screw installation method. On the one hand, it can achieve rapid installation and disassembly operations of the screen frame 4 and the screen cloth 5 without having to screw each screw one by one. This not only reduces the labor intensity of workers but also improves the installation and disassembly efficiency. On the other hand, it can avoid the occurrence of thread slipping caused by screwing the screws multiple times, ensuring the service life of the equipment and being beneficial to actual application and operation.

[0045] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
