Description

Technical Field

[0001] The utility model belongs to the technical field of screen printing machines, and particularly relates to an ink anti-leakage mechanism for screen printing machines. Background Technique

[0002] A screen printing machine is a machine that uses a screen printing plate for printing and belongs to a type of printing machine; it is mainly used for printing characters and images and is the general term for equipment for producing printed matter; the screen printing machine is representative in stencil printing machines, and the materials for making the screen include natural silk, nylon wire, copper wire, steel wire, or stainless steel wire, etc.; screen printing machines can be divided into types such as flat screen printing machines, curved screen printing machines, rotary screen printing machines, etc.; there are various types of screen printing machines, and according to different printing methods, they can be divided into the following several types: flat screen flat screen printing; flat screen curved screen printing; circular screen printing; indirect screen printing.

[0003] Currently, during screen printing, after printing is completed, there will be some ink on the screen. When the screen moves upward away from the substrate, some ink will leak down through the gaps in the screen under the action of its own gravity, resulting in too much ink on the product, thus causing a leakage phenomenon. Based on this, an ink anti-leakage mechanism for screen printing machines is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a simple-structured and reasonably designed ink anti-leakage mechanism for screen printing machines to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] An ink anti-leakage mechanism for screen printing machines includes a base, a fixed frame is fixedly connected to the top of the base, a guiding roller is rotatably connected to the fixed frame, a fitting mechanism is installed in the fixed frame, an adjusting mechanism is installed on the fixed frame, an anti-pollution mechanism is installed on the adjusting mechanism, and the anti-pollution part of the anti-pollution mechanism is attached to the top of the fitting mechanism.

[0007] As a further optimized scheme of the utility model, the fitting mechanism includes a fixing plate fixedly connected in the fixed frame, a telescopic rod is fixedly connected to the top of the fixing plate, a supporting plate is fixedly connected to the top of the telescopic rod, and a connecting spring is sleeved on the telescopic rod.

[0008] As a further optimized scheme of the utility model, the bottom of the connecting spring is fixedly connected to the top of the fixing plate, and the top of the connecting spring is fixedly connected to the bottom of the supporting plate.

[0009] As a further optimization solution of the present utility model, the adjusting mechanism includes a bidirectional threaded rod rotatably connected to the fixed frame. A first moving plate and a second moving plate are threadedly connected to the bidirectional threaded rod. A first plugging block is rotatably connected to one side of the first moving plate close to the second moving plate. A motor is fixedly connected to the side of the second moving plate away from the first moving plate. A rotating shaft is fixedly connected to the output end of the motor. A second plugging block is rotatably connected to one side of the second moving plate close to the first moving plate. The free end of the bidirectional threaded rod is rotatably connected to a handle.

[0010] As a further optimization solution of the present utility model, the rotating shaft penetrates through the second moving plate and is rotatably connected to the second moving plate. Both the first moving plate and the second moving plate are slidably connected to the top of the base. Both the first plugging block and the second plugging block are provided in a hexagonal prism shape. The part of the rotating shaft extending out of the second moving plate is provided in a hexagonal prism shape.

[0011] As a further optimization solution of the present utility model, the anti-fouling mechanism includes a paper feeding roller and a paper receiving roller arranged between the first moving plate and the second moving plate.

Specific embodiments

[0019] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0020] Embodiment

[0021] As Figures 1-4 shown, an ink anti-leakage mechanism for a screen printing machine includes a base 1. A fixing frame 2 is fixedly connected to the top of the base 1. A guiding roller 3 is rotatably connected to the fixing frame 2. A fitting mechanism is installed inside the fixing frame 2. An adjusting mechanism is installed on the fixing frame 2. An anti-fouling mechanism is installed on the adjusting mechanism. The anti-fouling part of the anti-fouling mechanism is attached to the top of the fitting mechanism. The fitting mechanism includes a fixing plate 401 fixedly connected inside the fixing frame 2. A telescopic rod 402 is fixedly connected to the top of the fixing plate 401. A supporting plate 404 is fixedly connected to the top of the telescopic rod 402. A connecting spring 403 is sleeved on the telescopic rod 402. The bottom of the connecting spring 403 is fixedly connected to the top of the fixing plate 401. The top of the connecting spring 403 is fixedly connected to the bottom of the supporting plate 404.

[0022] During use, first place the product to be printed on the anti-fouling part, and then printing can begin. At this time, due to the action of the screen, a downward pressing driving force will be generated on the supporting plate 404, causing the telescopic rod 402 to contract, and at the same time the connecting spring 403 is compressed. During the printing process, through the operation of the squeegee, the supporting plate 404 will be pressed downward again. At this time, the connecting spring 403 ensures the printing pressure when the squeegee scrapes the ink. After printing is completed, when the screen moves upward, the supporting plate 404 will push the printed product upward under the action of the connecting spring 403 and the telescopic rod 402 until the supporting plate 404 reaches the highest position. Then the screen moves away from the product again, and the printed product can be taken off;

[0023] After printing is completed, since the gap between the product and the screen is too large, the ink remaining on the screen leaks onto the product through the gap of the screen under its own gravity. At the same time, the time when there is a gap between the product and the screen after screen printing is shortened, thereby ensuring the quality of screen printing and reducing the probability of ink leakage.

[0024] As Figures 1-5 shown, the adjusting mechanism includes a bidirectional threaded rod 501 rotatably connected to the fixed frame 2. A first moving plate 503 and a second moving plate 504 are threadedly connected to the bidirectional threaded rod 501. A first plugging block 505 is rotatably connected to the side of the first moving plate 503 close to the second moving plate 504. A motor 506 is fixedly connected to the side of the second moving plate 504 away from the first moving plate 503. A rotating shaft 507 is fixedly connected to the output end of the motor 506. A second plugging block 508 is rotatably connected to the side of the second moving plate 504 close to the first moving plate 503. A handle 502 is rotatably connected to the free end of the bidirectional threaded rod 501. The rotating shaft 507 passes through the second moving plate 504 and is rotatably connected to the second moving plate 504. Both the first moving plate 503 and the second moving plate 504 are slidably connected to the top of the base 1. Both the first plugging block 505 and the second plugging block 508 are arranged in a hexagonal prism shape. The part of the rotating shaft 507 extending out of the second moving plate 504 is arranged in a hexagonal prism shape. The anti-pollution mechanism includes a paper feeding roller 601 and a paper receiving roller 603 arranged between the first moving plate 503 and the second moving plate 504. An anti-leakage paper 602 is wound on both the paper feeding roller 601 and the paper receiving roller 603. The anti-leakage paper 602 is an anti-pollution part. The anti-leakage paper 602 is attached to the guiding roller 3. The anti-leakage paper 602 is attached to the top of the supporting plate 404. Plugging holes 604 are opened at both ends of the paper feeding roller 601 and the paper receiving roller 603. The plugging holes 604 are adapted to the first plugging block 505, the second plugging block 508 and the rotating shaft 507.

[0025] When in use, anti-pollution mechanisms of different sizes can be selected according to the size of the pattern in screen printing. When installing the anti-pollution mechanism, first place the paper feeding roller 601 between the first plugging block 505 and the second plugging block 508, and make the anti-leakage paper 602 attached to the supporting plate 404. At the same time, make the paper receiving roller 603 located between the first plugging block 505 and the rotating shaft 507. Then hold the handle 502 and rotate the bidirectional threaded rod 501 to make the first moving plate 503 and the second moving plate 504 slide inwards or outwards simultaneously until the first plugging block 505, the second plugging block 508 and the rotating shaft 507 enter the plugging holes 604, and the installation of the anti-pollution mechanism is completed. After one printing is completed, start the motor 506 to make the rotating shaft 507 rotate, thereby driving the paper receiving roller 603 to rotate, winding the anti-leakage paper 602 onto the paper receiving roller 603, and at the same time making the paper feeding roller 601 release the anti-leakage paper 602;

[0026] The collection of the leaked ink is further realized, preventing the ink from leaking onto the supporting plate 404, which may cause the need for personnel to clean the supporting plate 404, reducing the burden on the personnel. At the same time, it prevents the ink from polluting the supporting plate 404. In addition, leak-proof papers 602 of different sizes can be used as needed, preventing waste of resources caused by using a leak-proof paper 602 of a larger size for a smaller printed pattern.

[0027] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
