Description

Technical Field

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

[0002] Screen printing machines are machines used to print text and images. They are a general term for machines or equipment used to produce printed materials, and come in many types, including flatbed screen printing and curved flatbed screen printing. Curved flatbed screen printing offers the best printing results. Its internal printing screen is coiled on a screen tube, and the rotation of the screen tube carries the ink out of the printing machine. Because the screen tube has a limited lifespan and needs to be replaced periodically, it is clamped inside the printing machine using a clamping device.

[0003] However, existing screen printing cylinders require the use of nuts and screws for installation and removal, which is cumbersome. Furthermore, the clamping distance cannot be adjusted according to the size of the screen printing cylinder, reducing the overall usability of the equipment and limiting its application. Therefore, this screen printing cylinder clamping device does not meet the current requirements, and we propose a screen printing clamping device for screen printing. Utility Model Content

[0004] The purpose of this utility model is to provide a screen clamping device for screen printing, so as to solve the problems mentioned in the background art, which are that the existing screen tubes need to be installed and disassembled by the cooperation of nuts and screws when replacing them, which is cumbersome. In addition, the entire device cannot adjust the clamping distance according to the size of the screen tube, thereby reducing the usage frequency of the entire device and causing the limitations of the screen tube clamping device for screen printing machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screen printing clamping device, comprising a base, a fixing plate fixedly mounted on one side of the upper surface of the base, a first motor mounted on one side of the outer surface of the fixing plate, a rotating shaft provided on the other side of the outer surface of the fixing plate, four strip-shaped inserts evenly mounted on the outer surface of the rotating shaft, and a movable plate movably mounted on the other side of the upper surface of the base via a moving mechanism. A cylinder is provided on the opposite side of the outer surface of the movable plate and the rotating shaft, and a circular slot is provided on one side of the outer surface of one of the cylinders. The inner wall of the circular slot is evenly distributed with... There are four strip-shaped slots. A circular groove is provided on one side of the opposite outer surface of each of the two cylinders. A roller is provided inside the circular groove. A wire mesh tube is fixedly connected to one side of the opposite two rollers. A clamping mechanism is provided at the front and rear of each roller. The clamping mechanism includes arc-shaped clamping plates. A threaded rod is provided on one side of the opposite outer surface of each pair of arc-shaped clamping plates. The threaded rod is installed on the front and rear faces of the cylinder through threaded holes. A rotating plate is installed on one side of the opposite outer surface of each pair of threaded rods. A limiting mechanism is provided below the rotating plate, allowing the rotating plate to be limited by the limiting mechanism.

[0006] Preferably, support columns are installed at the four corners of the lower end face of the base, and anti-slip pads are fixedly connected to the lower end face of each support column. The output end of the first motor is fixedly connected to one end of the rotating shaft through a coupling. The rotating shaft can be inserted into the inner side of the circular slot. The strip plate can be inserted into the inner side of the strip slot. The other cylinder is rotatably connected to the outer surface of the movable plate through a bearing.

[0007] Preferably, the moving mechanism includes a lead screw, which is disposed in front of and behind one side of the upper end face of the base via a transverse groove. A threaded plate is sleeved on the outer surface of the lead screw, and the upper end face of the threaded plate is fixedly connected to the lower end face of the moving plate.

[0008] Preferably, two second motors are installed on one side of the outer surface of the base. The output end of the second motor is fixedly connected to one end of the lead screw through a short shaft, and the other end of the lead screw is rotatably connected to the inner wall of the transverse groove through a bearing.

[0009] Preferably, the threaded rod and the threaded hole are connected by threads, the threaded rod and the arc-shaped clamp are rotatably connected by bearings, and a miniature air pump is installed on the rear end face of both the moving plate and the fixed plate. The miniature air pump is connected to the airbag through a connecting pipe.

[0010] Preferably, the limiting mechanism includes a horizontal plate, a through hole is provided on the upper end surface of the horizontal plate, a pull rod is provided inside the through hole, a spring is sleeved on the outer surface of the pull rod, and a limiting rod is installed on the upper end surface of the pull rod.

[0011] Preferably, the horizontal plate is fixedly connected to the outer surface of the cylinder, the lower end face of the pull rod is fixedly connected to a pull plate, the lower end face of the rotating plate is provided with a limit hole, and the limit rod can be inserted into the inner side of the limit hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting up a movable plate and a movable mechanism, can control the switch of the second motor. The second motor drives the lead screw to rotate, thereby driving the threaded plate to move on the outer surface of the lead screw, and driving the movable plate to move. The distance between the movable plate and the fixed plate can be adjusted, which facilitates the installation and disassembly of the roller and the wire mesh cylinder. It can clamp wire mesh cylinders of different lengths, improving its applicability.

[0014] 2. This utility model, by incorporating a clamping mechanism and a limiting mechanism, allows for easy replacement of the wire mesh cylinder. First, the two pull rods are pulled downwards using the pull plate to release the limiting effect on the rotating plate. Then, the threaded rod is rotated, causing it to move outwards from the inside of the threaded hole, thus moving the arc-shaped clamping plate away from the outer surface of the roller shaft and releasing the clamping effect on the roller shaft. At this point, the moving mechanism moves the moving plate away from the wire mesh cylinder, causing the roller shaft to leave the inner side of the circular groove. Similarly, the limiting effect on the other side of the roller shaft is released, allowing the wire mesh cylinder to be removed from the side opposite the moving plate and the fixed plate for replacement. During installation, the pull rods are first pulled downwards to release the limiting effect on the rotating plate. After the roller shaft is inserted into the inner side of the circular groove, the threaded rod is rotated, causing it to move inward within the threaded hole. This moves the arc-shaped clamping plate closer to the outer surface of the roller shaft. A miniature air pump and airbag are included; the air pump can be turned on to inflate the airbag, improving the tightness of the arc-shaped clamping plate's grip on the roller shaft. Then, the pull plate is released, and under the action of the spring, it moves the limiting rod upward. The limiting rod engages with the inner side of the limiting hole, limiting the rotation plate and improving the stability of the threaded rod. This further enhances the stability of the arc-shaped clamping plate, making the clamping of the screen tube more stable, increasing the firmness of the screen tube clamping, and improving printing quality.

The operation of the first motor 8 can drive the rotating shaft 9 to rotate. When the rotating shaft 9 is inserted into the inner side of the circular slot 13 and the strip plate 11 is inserted into the inner side of the strip slot 12, the rotation of the rotating shaft 9 can drive the cylinder 3 on the left side to rotate, thereby driving the roller 4 to rotate.

[0024] The moving mechanism 10 includes a lead screw 1003, which is disposed in front of and behind the upper end face of the base 1 via a transverse groove 1001. A threaded plate 1002 is sleeved on the outer surface of the lead screw 1003. The upper end face of the threaded plate 1002 is fixedly connected to the lower end face of the moving plate 2.

When the second motor 1004 is working, it can drive the short shaft to rotate, thereby driving the lead screw 1003 to rotate, thus improving the stability of the rotation of the lead screw 1003.

[0026] The threaded rod 1502 is connected to the threaded hole 1504 by threads, and the threaded rod 1502 is rotatably connected to the arc-shaped clamping plate 1501 by bearings.

The threaded rod 1502 can move left and right inside the threaded hole 1504, driving the arc-shaped clamping plate 1501 to move. When the miniature air pump works, it can inflate the air bag 1503, so that the arc-shaped clamping plate 1501 clamps the roller shaft 4 tightly.

[0027] The limiting mechanism 14 includes a horizontal plate 1404, with a through hole 1403 extending through the upper end face of the horizontal plate 1404. A pull rod 1406 is provided inside the through hole 1403, and a spring 1405 is sleeved on the outer surface of the pull rod 1406. A limiting rod 1402 is installed on the upper end face of the pull rod 1406. The horizontal plate 1404 is fixedly connected to the outer surface of the cylinder 3. A pull plate 1407 is fixedly connected to the lower end face of the pull rod 1406. A limiting hole 1401 is provided on the lower end face of the rotating plate 1505. The limiting rod 1402 can be inserted into the inner side of the limiting hole 1401 to improve the stability of the connection between the horizontal plate 1404 and the cylinder 3. The pull rod 1406 can be pulled by the pull plate 1407 to move the limiting rod 1402. When the limiting rod 1402 leaves the inner side of the limiting hole 1401, the limiting of the rotating plate 1505 can be released.

[0028] When using this screen printing screen clamping device, the power is first turned on. Equipped with a moving plate 2 and a moving mechanism 10, the second motor 1004 is controlled by a switch. The second motor 1004 rotates the lead screw 1003, causing the threaded plate 1002 to move on the outer surface of the lead screw 1003, thus moving the moving plate 2. The distance between the moving plate 2 and the fixed plate 7 can be adjusted, facilitating the installation and removal of the roller 4 and the screen tube 5. It can clamp screen tubes 5 of different lengths, improving its applicability. The clamping mechanism 15 and the limiting mechanism 14 allow for adjustments when needed. When replacing the wire mesh cylinder 5, first pull down the two pull rods 1406 using the pull plate 1407 to release the restriction on the rotating plate 1505. Then rotate the threaded rod 1502, causing it to move outward from the inside of the threaded hole 1504, thus moving the arc-shaped clamping plate 1501 away from the outer surface of the roller shaft 4 and releasing the clamping of the roller shaft 4. At this time, the moving plate 2 is moved away from the wire mesh cylinder 5 using the moving mechanism 10, and the roller shaft 4 moves away from the inside of the circular groove 6. Similarly, the restriction on the other side of the roller shaft 4 is released, and the wire mesh cylinder 5 can be removed from the side opposite the moving plate 2 and the fixed plate 7 for further processing. For replacement, during installation, first pull down the pull rod 1406 to release the limit on the rotating plate 1505. Then, insert the roller shaft 4 into the inner side of the circular groove 6. By rotating the threaded rod 1502, the threaded rod 1502 moves inward inside the threaded hole 1504, causing the arc-shaped clamping plate 1501 to move closer to the outer surface of the roller shaft 4. Since a miniature air pump and airbag 1503 are provided, the switch of the miniature air pump can be turned on to inflate the airbag 1503, improving the tightness of the arc-shaped clamping plate 1501 in clamping the roller shaft 4. Then, release the pull plate 1407, which is then held in place by the spring 140. Under the action of 5, the limiting rod 1402 moves upward and is engaged in the inner side of the limiting hole 1401, limiting the rotating plate 1505 and improving the stability of the threaded rod 1502, thereby further improving the stability of the arc-shaped clamping plate 1501, making the clamping of the screen tube 5 more stable, improving the firmness of the clamping of the screen tube 5, and improving the printing quality. This utility model can clamp screen tubes 5 of different lengths, improving applicability, and facilitating the disassembly and installation of the screen tube 5, improving efficiency. At the same time, the clamping of the screen tube 5 is more stable, improving the printing quality.
