Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, specifically to a screen printing device. Background Art

[0002] Screen printing refers to the process of creating a screen printing plate with images and text using a photosensitive method. Screen printing consists of five main elements: the screen printing plate, the squeegee, the ink, the printing table, and the substrate. It utilizes the basic principle that ink can pass through the mesh openings of the screen printing plate in the image areas, while ink cannot pass through the openings in the non-image areas. The squeegee applies pressure to the ink areas of the screen printing plate while moving at a constant speed towards the other end. During this movement, the ink is forced through the mesh openings in the image areas onto the substrate.

[0003] For example, the national authorized patent announcement number CN209240657U discloses a screen printing device, including an exposure host and an automatic feeding device located on one side of the exposure host. The exposure host includes a worktable with a feeding station and an exposure station. An exposure head is installed at the exposure station. The automatic feeding device includes a feeding platform with a robotic arm mounted on it. The robotic arm's terminal is equipped with a first suction cup assembly. The robotic arm can switch between the replenishment station and the feeding station to deliver the material tray to the feeding station. A transfer device is installed on the feeding platform to move the material tray to the finished product storage station. This printing equipment can realize automatic feeding, exposure, and unloading of mobile phones, achieving a higher degree of automation and reducing labor costs.

[0004] However, the aforementioned screen printing equipment cannot quickly change the screen plate according to different patterns. This makes it difficult for the production line to adapt to different production tasks in production environments that require frequent changes of different patterns or designs. A lot of time needs to be spent changing the screen plate for printing, which will lead to long machine downtime and reduce overall production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a screen printing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A screen printing device includes: a screen printing machine body, a linear module fixedly installed on the upper surface of the screen printing machine body, an printing table fixedly installed between the moving blocks on the upper surface of the linear module, a cross slide fixedly installed at the other end of the upper surface of the screen printing machine body, and a squeegee fixedly installed at one end of the moving block of the cross slide.

[0008] The screen printing machine body has a connecting frame fixedly installed on its upper surface. A brake motor is fixedly installed at one end of the connecting frame. A changing disc is fixedly installed at one end of the output shaft of the brake motor. A guide cylinder is fixedly installed at one end of the changing disc. A printing mechanism is slidably installed inside the guide cylinder.

[0009] The lower end of the outer surface of the connecting frame is fixedly installed with a pushing mechanism. The pushing mechanism can be inserted into the pressing port to make it fit into the guide cylinder, and can push the printing mechanism to fit against the upper surface of the printing table. The pressing port is connected to the guide cylinder.

[0010] Preferably, the rotating disc is able to drive the printing mechanism inside the guide cylinder to be flush with the printing table via a brake motor.

[0011] Preferably, during the process of the rotating disc driving the four sets of printing mechanism rings to rotate, the scraper will be located at the center of the four sets of printing mechanisms via the cross slide.

[0012] Preferably, the printing mechanism includes a screen printing plate, one end of which is fixedly mounted with a guide block, and the screen printing plate is slidably mounted inside a guide cylinder via the guide block.

[0013] Preferably, the screen printing plate slides vertically down within the guide cylinder via the guide block, allowing it to come into contact with the upper surface of the printing table.

[0014] Preferably, a sliding column is fixedly installed inside the guide cylinder, a guide block is slidably installed on the outer surface of the sliding column, and a spring is fitted on the outer surface of the sliding column.

[0015] Preferably, one end of the spring is fixedly connected to one end of the disassembly plate, the disassembly plate is disassembled and installed at one end of the guide cylinder by bolts, blocking the guide block inside, while the other end of the spring touches one end of the guide block.

[0016] Preferably, the pushing mechanism includes an electric push rod, which is fixedly installed on the lower end of the outer surface of the connecting frame. A connecting arm is fixedly installed on one end of the piston rod of the electric push rod, and a push block is fixedly installed on the other end of the connecting arm.

[0017] Preferably, the push block is flush with the top pressure port and can be pushed into the guide cylinder.

[0018] Preferably, the push block inserted into the guide cylinder can push the guide block to move vertically downward.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. Through the design of linear modules, printing tables, cross slides, squeegees, rotating discs, brake motors, printing mechanisms, and push-mounting mechanisms, in printing tasks that require frequent screen replacements, operators can pre-assemble the required screens onto the printing mechanism. Then, during printing, operators can activate the brake motor to drive the rotating disc to rotate multiple times. The rotating disc will then drive the printing mechanism, which is slidably installed in the guide cylinder, to rotate in turn until the required printing mechanism is flush with the printing table. Then, the push-mounting mechanism can be activated to insert into the pressure port. The push-mounting mechanism inserted into the pressure port will touch one end of the printing mechanism, pushing the printing mechanism to slide vertically down in the guide cylinder, so that the printing mechanism touches and adheres to the upper surface of the printed material placed on the upper surface of the printing table. Then, the squeegee will scrape the ink through the cross slide against the screen of the printing mechanism to perform the printing operation, allowing the ink to be printed onto the upper surface of the printed material through the screen.

[0021] By rotating the screen printing plate using a rotating disc, the screen printing plate can be changed quickly. This allows for faster switching between different printing tasks and reduces the time required for each screen printing plate change. This means the machine can be in operation for more time, thereby improving overall production efficiency. Furthermore, the quick rotation function reduces the workload of operators and lowers the skill requirements, thus reducing labor costs.

[0022] 2. Through the design of the screen printing plate, guide block, spring, disassembly plate, electric push rod, connecting arm, and push block, in printing tasks requiring frequent screen printing plate changes, the operator can pre-slide the required screen printing plate into the guide cylinder via the guide block, while simultaneously allowing the sliding column to slide through the guide block. Then, the spring fixedly connected to one end of the disassembly plate can be fitted onto the outer surface of the sliding column, and the disassembly plate can be bolted to one end of the guide cylinder. This ensures that the spring at one end of the disassembly plate always remains in contact with the guide block. During printing, the operator can activate the brake motor to rotate the rotating disc multiple times. The rotating disc will then rotate the guide block and screen printing plate, which are slidably installed inside the guide cylinder, in rotation until the required screen printing plate is flush with the printing table. Then, the electric push rod can be activated to push the push block at one end of the connecting arm into the pressure port. This allows the connecting arm to push the push block into the guide cylinder, where the push block will contact one end of the guide block, causing the guide block to move the screen printing plate vertically downwards until it contacts the upper surface of the printing table. The ink is applied to the upper surface of the printed material, and simultaneously, the guide block presses against one end of the spring. The spring then applies an upward force to the guide block, and the squeegee, via the cross slide, scrapes the ink onto the screen plate to perform the printing operation. This allows the ink to be printed onto the upper surface of the printed material through the screen plate. When printing a second set of printed materials and needing to replace the screen plate again, the electric push rod can be restarted to pull the push block out of the guide cylinder and the pressing port through the connecting arm. The guide block, no longer under pressure, is then springed up by the spring force, detaching it from the upper surface of the printing table. The brake motor can then be activated to rotate the rotating disc, thus rotating and changing the screen plate. This screen plate rotation function significantly reduces machine downtime, allowing the production line to operate continuously, thereby significantly improving production efficiency. It also allows for quick switching between different screen plates, enabling the production line to more flexibly respond to diverse market demands. Enterprises can quickly adjust production plans to meet customers' personalized needs. Attached Figure Description

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please see Figures 1-5 This utility model provides a technical solution:

[0031] like Figures 1-3 As shown, a screen printing device includes: a screen printing machine body 1, a linear module 101 fixedly installed on the upper surface of the screen printing machine body 1, an ink table 102 fixedly installed between the moving blocks on the upper surface of the linear module 101, a cross slide 103 fixedly installed at the other end of the upper surface of the screen printing machine body 1, and a squeegee 109 fixedly installed at one end of the moving block of the cross slide 103.

[0032] Among them, a connecting frame 104 is fixedly installed on the upper surface of the screen printing machine body 1, a brake motor 106 is fixedly installed at one end of the connecting frame 104, a rotating disk 105 is fixedly installed at one end of the output shaft of the brake motor 106, a guide cylinder 107 is fixedly installed at one end of the rotating disk 105, and a printing mechanism 2 is slidably installed inside the guide cylinder 107.

[0033] Among them, a push-mounting mechanism 3 is fixedly installed on the lower end of the outer surface of the connecting frame 104. The push-mounting mechanism 3 can be inserted into the pressing port 108 so that it is inserted into the guide cylinder 107, and can push the printing mechanism 2 to fit against the upper surface of the printing table 102. The pressing port 108 is connected to the guide cylinder 107.

[0034] The rotating disc 105 can drive the printing mechanism 2 inside the guide cylinder 107 to be flush with the printing table 102 via the brake motor 106.

[0035] During the rotation of the four printing mechanisms 2 by the rotating disc 105, the scraper 109 will be located at the center of the four printing mechanisms 2 via the cross slide 103.

[0036] Through the design of the linear module 101, printing table 102, cross slide 103, squeegee 109, rotating disc 105, brake motor 106, printing mechanism 2, and pushing mechanism 3, in printing tasks requiring frequent screen printing plate 201 changes, the operator can pre-assemble the required screen printing plate 201 onto the printing mechanism 2. Then, during printing, the operator can activate the brake motor 106 to drive the rotating disc 105 to rotate 90° multiple times. The rotating disc 105, in turn, drives the printing mechanism 2, which is slidably mounted inside the guide cylinder 107, to rotate in rotation until... After rotating the printing mechanism 2 to be flush with the printing table 102, the push mechanism 3 can be activated and inserted into the pressure port 108. The push mechanism 3 inserted into the pressure port 108 will touch one end of the printing mechanism 2, and can push the printing mechanism 2 to slide vertically down in the guide tube 107, so that the printing mechanism 2 touches and adheres to the upper surface of the printed matter placed on the upper surface of the printing table 102. Then the squeegee 109 will touch the screen plate 201 of the printing mechanism 2 through the cross slide 103 to scrape the ink and perform the printing operation, so that the ink can be printed on the upper surface of the printed matter through the screen plate 201.

[0037] By rotating the screen printing plate 201 via the rotating disc 105, the screen printing plate 201 can be quickly changed, allowing for faster switching between different printing tasks and reducing the time required for each screen printing plate 201 change. This means the machine can be in working condition for more time, thereby improving overall production efficiency. Furthermore, the quick rotation function also reduces the workload of operators and lowers the skill requirements, thus reducing labor costs.

[0038] like Figures 4-5 As shown, the printing mechanism 2 includes a screen printing plate 201, a guide block 202 is fixedly installed at one end of the screen printing plate 201, and the screen printing plate 201 is slidably installed in the guide cylinder 107 through the guide block 202.

[0039] The screen printing plate 201 slides vertically down in the guide cylinder 107 via the guide block 202, and can then come into contact with the upper surface of the printing pad 102.

[0040] A sliding column 203 is fixedly installed inside the guide cylinder 107. A guide block 202 is slidably installed on the outer surface of the sliding column 203. A spring 204 is fitted on the outer surface of the sliding column 203.

[0041] One end of the spring 204 is fixedly connected to one end of the disassembly plate 205. The disassembly plate 205 is disassembled and installed on one end of the guide cylinder 107 by bolts, blocking the guide block 202 inside, while the other end of the spring 204 touches one end of the guide block 202.

[0042] The pushing mechanism 3 includes an electric push rod 301, which is fixedly installed on the lower end of the outer surface of the connecting frame 104. A connecting arm 302 is fixedly installed on one end of the piston rod of the electric push rod 301, and a push block 303 is fixedly installed on the other end of the connecting arm 302.

[0043] The push block 303 can be flush with the top pressure port 108 and pushed into the guide cylinder 107.

[0044] The push block 303 inserted into the guide cylinder 107 can push the guide block 202 to move vertically downward.

[0045] Through the design of the screen stencil 201, guide block 202, spring 204, disassembly plate 205, electric push rod 301, connecting arm 302, and push block 303, in printing tasks that require frequent replacement of the screen stencil 201, the operator can pre-slide the required screen stencil 201 into the guide cylinder 107 via the guide block 202, while simultaneously allowing the sliding column 203 to slide through the guide block 202. Then, the spring 204, fixedly connected to one end of the disassembly plate 205, can be fitted onto the outer surface of the sliding column 203, and the disassembly plate 205 can be bolted to one end of the guide cylinder 107. This ensures that the spring 204 at one end of the disassembly plate 205 always remains in contact with the guide block 202. At one end, during the printing process, the operator can activate the brake motor 106 to drive the rotating disc 105 to rotate 90° multiple times. The rotating disc 105 will then drive the guide block 202 and the screen printing plate 201, which are slidably installed inside the guide cylinder 107, to rotate alternately until the screen printing plate 201 is aligned with the printing table 102. Then, the electric push rod 301 can be activated to push the push block 303 at one end of the connecting arm 302 into the pressure port 108. This allows the connecting arm 302 to drive the push block 303 into the guide cylinder 107. The push block 303 inside the guide cylinder 107 will then contact one end of the guide block 202, allowing the guide block 202 to rotate. The guide block 202 moves the screen plate 201 vertically downward until it touches the upper surface of the printed material on the printing table 102. At the same time, the guide block 202 presses against one end of the spring 204, and the spring 204 applies an upward elastic force to the guide block 202. Subsequently, the squeegee 109 touches the screen plate 201 through the cross slide 103 to scrape ink and perform the printing operation. This allows the ink to be printed onto the upper surface of the printed material through the screen plate 201. When printing a second set of printed materials and the screen plate 201 needs to be replaced again, the electric push rod 301 can be restarted to push the push block 303 from the guide cylinder 102 through the connecting arm 302. 07 and the top pressure port 108 are pulled out, and the guide block 202, which is not under the pressure, is pushed up by the elastic force of the spring 204, so that it is separated from the upper surface of the printing table 102. Then the brake motor 106 can be started to drive the rotating disk 105 to rotate and realize the operation of rotating and changing the screen printing plate 201. This function of rotating the screen printing plate 201 can greatly reduce the machine downtime, enable the production line to operate continuously, thereby significantly improving production efficiency. It can also quickly switch between different screen printing plates 201, so that the production line can respond more flexibly to diverse market demands. Enterprises can quickly adjust production plans to meet the personalized needs of customers.

[0046] Based on the above technical solution, the working steps of this solution are summarized as follows: During use, the operator places the printed material on the upper surface of the printing table 102. After placement, the linear module 101 is activated to slide the printing table 102 until it is flush with the screen printing plate 201. This allows the printing table 102 to align the printed material with the screen printing plate 201. Subsequently, the operator can activate the brake motor 106 to rotate the rotating disc 105 multiple times by 90°. The rotating disc 105 will then... The guide block 202 and the screen printing plate 201, which are slidably installed inside the guide cylinder 107, rotate alternately until the screen printing plate 201 is flush with the printing table 102. Then, the electric push rod 301 is activated to push the push block 303 at one end of the connecting arm 302 into the pressing port 108. This allows the connecting arm 302 to drive the push block 303 into the guide cylinder 107. The push block 303 inside the guide cylinder 107 will then contact one end of the guide block 202, allowing the guide block to... 202 drives the screen 201 to move vertically downwards until it touches the upper surface of the printed material on the printing table 102. At the same time, the guide block 202 presses against one end of the spring 204, and the spring 204 applies an upward elastic force to the guide block 202. Subsequently, the squeegee 109 touches the screen 201 through the cross slide 103 to scrape ink and perform the printing operation. This allows the ink to be printed onto the upper surface of the printed material through the screen 201, completing the printing operation. Meanwhile, for the second... When printing is being done and the screen printing plate 201 needs to be replaced again, the electric push rod 301 can be restarted to pull the push block 303 out of the guide cylinder 107 and the pressure port 108 through the connecting arm 302. The guide block 202, which is not under pressure, will be pushed up by the elastic force of the spring 204, so that it is detached from the upper surface of the printing table 102. Then the brake motor 106 can be started to drive the rotating disk 105 to rotate, so as to realize the operation of rotating and rotating the screen printing plate 201.

[0047] In summary, the function of this rotating screen printing plate 201 can significantly reduce machine downtime, allowing for faster switching between different printing tasks and enabling the production line to operate continuously, thereby significantly improving production efficiency. Furthermore, the ability to quickly switch between different screen printing plates 201 allows the production line to respond more flexibly to diverse market demands, and enables companies to quickly adjust production plans to meet customers' personalized needs.
