Description

Technical Field

[0001] The utility model relates to the technical field of screen clamp replacement, in particular to a quick-replacement screen clamp for a drum-type screen printing machine. Background Art

[0002] Screen printing, also known as silk screen printing, is an image reproduction technology that uses silk screen as the plate-making material and uses a scraper to scrape and squeeze the ink on the printing plate to print the ink on the substrate. When the screen is used for a long time, it usually needs to be disassembled for maintenance or cleaning. However, most existing printing machines need to dismantle the device before replacing the screen, which is quite time-consuming.

[0003] A search for the above-mentioned problem revealed that among the currently disclosed prior arts, there is a fully automatic high-precision screen printing machine structure proposed in publication number CN216545247U. This structure places the screen on a placement rack and fixes the screen with a fixing plate. When disassembling the screen, the fixing plate is rotated to open it and then the screen is detached. However, when disassembling the screen, it needs to be manually disassembled and installed. Since there is ink on the screen, the ink may adhere to the operator's body or hands when disassembling the screen. In addition, if the screen is heavy, it is also more laborious to manually disassemble and carry it. Utility Model Content

By starting the motor 104, the motor 104 drives the reciprocating screw 102 to rotate in the support cover 101, so that the screw nut 103 moves on the support cover 101 and the reciprocating screw 102, which can drive the splint 104 and the splint 20 5 to move left and right, thereby realizing the transportation and replacement of the screen 1.

[0029] In this embodiment, reference Figure 3The adjustment component includes a support plate 201 and a sliding rod 202. There are two support plates 201, which are fixedly mounted on both sides of the splint 1 4 respectively. There are two sliding rods 202, which are fixedly mounted on the two support plates 201 respectively, and the splint 2 5 is slidably mounted on the two sliding rods 202.

[0030] In this embodiment, reference Figure 3 The adjustment component also includes a fixing frame 203 and a bolt 204. There are two fixing frames 203, and the two fixing frames 203 are respectively fixedly mounted on both sides of the clamping plate 4, and a threaded hole is opened on the fixing frame 203, and a threaded hole is opened on the clamping plate 2 5, and the bolt 204 is adapted to the threaded hole. A pull handle 8 is fixedly installed on the top of the clamping plate 2 5. The clamping plate 2 can be moved up and down on the slide rod 202 by holding the pull handle 8 and attached to the screen 1. Then, the bolt 204 is threadedly connected to the fixing frame 203 and the clamping plate 2 5 to fix it. The pull handle 8 on the side of the support cover 101 can be held by hand, and the movable frame 3 is slidably mounted in the slide groove of the printing frame 2, so that it can be pushed to make the clamping plate 1 4 fit the side bottom surface of the screen 1, so that the clamping plate 1 4 and the clamping plate 2 5 clamp and fix the screen 1.

[0031] In this embodiment, reference Figure 4 The lifting assembly includes a placing plate 301, a sliding plate 302, a cylinder 303 and a lifting frame 304.

There are two cylinders 303, and both cylinders 303 are mounted on the sliding plate 302. The bottom end of the lifting frame 304 is fixedly connected to the output end of the cylinder 303, and the top end of the lifting frame 304 is fixedly connected to the bottom end of the moving frame 3. The lifting frame 304 is slidably mounted in the through groove of the printing frame 2, so when the moving frame 3 is pushed, the sliding frame 302 can be driven. The plate 302 and the cylinder 303 move synchronously, and after the clamping is completed, the cylinder 303 is started, and the cylinder 303 pushes the movable frame 3 and the support cover 101 to move upward, thereby lifting the screen 1, and then moving it left and right. The replacement frame 6 is fixedly installed on both sides of the brush frame, and a placement slot is provided on the replacement frame 6. The replaced screen 1 is placed on the replacement frame 6, and a new screen 1 can be placed on the replacement frame 6 at the other end to clamp and replace it. The replacement frame 6 and the support frame 7 are at the same horizontal position, and the replacement frame 6 is at the same height as the support frame 7, so it is more convenient to move.

[0032] When the screen 1 is replaced, the screen 1 can be placed in the groove of the support frame 7 and clamped, so as to prevent the screen 1 from sliding during printing. When it needs to be replaced, the handle 8 on the side of the support cover 101 can be pushed to slide the movable frame 3 toward the position of the screen 1. When the sliding movable frame 3 slides, the cylinder 303 can also be synchronously slid on the placement plate 301 through the connection of the lifting frame 304, so that the clamp 1 4 is attached to the side bottom surface of the screen 1, and then the handle 8 at the top of the clamp 2 5 is pulled to slide down on the slide bar 202 and attach it to the top of the screen 1, and then the bolt 204 is threaded into the threaded hole of the fixing frame 203 and the clamp 1 4 for fixed clamping. After clamping is completed, the cylinder 303 is started, and the cylinder 303 pushes the lifting frame 304 to move up, thereby pushing the movable frame 3 and the support cover 101 to drive the clamp 1 4, the clamp 2 5 and the screen 1 to move up. Start the motor 104, which drives the reciprocating screw 102 to rotate in the support cover 101. It should be added that the screw nut 103 fits against the inner side of the support cover 101, so that the screw nut 103 moves on the support cover 101 and the reciprocating screw 102, driving the screen 1 to move left and right, and move it to the replacement rack 6 on one side of the printing machine frame 2, place it on it, and then move it to the replacement rack 6 at the other end again. The replacement rack 6 at the other end can place a new screen 1, thereby clamping and moving the new screen 1, and moving it into the groove of the support rack 7 to continue subsequent printing work.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
