Description

Technical Field

[0001] This utility model relates to the field of screen printing machine feeding, specifically an automatic feeding device for an intelligent servo screen printing machine. Background Technology

[0002] Screen printing is short for "silk screen printing". Screen printing involves stretching silk fabric, synthetic fiber fabric, metal mesh, etc. on a screen frame, and making a screen printing plate by manually cutting paint film or photochemical plate making. During printing, the ink is forced through the mesh of the image area by the pressure of a squeegee and transferred to the substrate to form the image and text that is the same as the original design. After printing, the substrate needs to be dried to allow the ink to dry and solidify on the surface of the substrate.

[0003] Chinese Patent CN210759724U discloses a screen printing machine feeding device. This utility model relates to a screen printing machine feeding device, which includes an unwinding roller. A guide box for limiting the printing material is provided on one side of the unwinding roller. The guide box has an inlet and an outlet for the printing material to pass through on both sides. A first guide roller is provided inside the guide box near the inlet, and a second guide roller is provided inside the guide box near the outlet. The first guide roller and the second guide roller are parallel to each other in the horizontal direction. By setting up the guide box, the printing material is guided and limited by the guide box after it comes out of the unwinding roller, thereby restricting the printing material to a certain position. This is beneficial for the printing material to enter the designated position of the screen printing machine better, and it also helps to keep the surface of the printing material flat when it enters the screen printing machine, which is convenient for pattern printing.

[0004] However, in the above technical solution, the guide box guides and limits the printing material after it comes out of the unwinding roller, thus confining the printing material to a certain position. This facilitates the printing material entering the designated position of the screen printing machine. However, when screen printing on various specifications of gauze, the fixing facilities of the screen printing machine need to fix different gauze, which wastes a lot of time during operation and reduces production efficiency. Therefore, this utility model proposes an automatic feeding device for an intelligent servo screen printing machine to solve the above-mentioned technical problems. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: an automatic feeding device for an intelligent servo screen printing machine, the automatic feeding device for an intelligent servo screen printing machine includes: a feeding frame 1, an electric push rod 2 is provided at the bottom of the feeding frame 1, and a push plate 3 is provided at the lifting end of the electric push rod 2;

[0023] Positioning frame 4, a moving screw 5 is screwed into the positioning frame 4, a first bearing 6 is sleeved on one end of the moving screw 5, an mounting plate 7 is provided on the surface of the first bearing 6, a lifting screw 8 is screwed into the mounting plate 7, a limit bearing 9 is sleeved on one end of the lifting screw 8, and a pressing plate 10 is provided on the surface of the limit bearing 9.

[0024] First, place the material in the positioning frame 4. Then, rotate the moving screw 5 according to the material of different lengths. This will allow the mounting plate 7 to move in conjunction with the first bearing 6. Once the mounting plate 7 has been moved to the appropriate distance, rotate the lifting screw 8 to move the pressing plate 10 down, thereby positioning the material. Then, start the electric push rod 2 to move the positioning frame 4 up for easier material loading.

[0025] Example 2: Based on Example 1, an installation plate 7 is provided to facilitate the positioning of materials of different lengths. The pusher plate 3 is fixedly connected to the lifting end of the electric push rod 2. The pusher plate 3 has an overall "U" shaped plate structure and can lift the positioning frame 4. The installation plate 7 has an overall "L" shaped plate structure and is in contact with the surface of the positioning frame 4. The installation plate 7 can move within the positioning frame 4. One end of the moving screw 5 is fixedly connected to the inner ring surface of the first bearing 6. The pressing plate 10 has an overall square plate structure. One end of the lifting screw 8 is fixedly connected to the inner ring surface of the limit bearing 9. The pressing plate 10 can move up and down within the pressing plate 10.

[0026] In use, the first moving screw 5 can be rotated in conjunction with the first bearing 6, so that the mounting plate 7 can be moved within the positioning frame 4. When the mounting plate 7 is moved, it contacts the bottom of the positioning frame 4, thus preventing the mounting plate 7 from rotating when the moving screw 5 is rotated. Then, the pressing plate 10 is moved down by the lifting screw 8, and the pressing plate 10 is moved within the mounting plate 7. The mounting plate 7 has an overall "L" shaped plate structure, which can prevent the pressing plate 10 from rotating within the mounting plate 7.

[0027] Example 3: Based on Example 2, in order to facilitate the removal and limiting of the positioning frame 4, a limiting plate 12 is set. A baffle 11 is set on the surface of the loading rack 1. A lifting port is opened on the surface of the loading rack 1. The limiting plate 12 is set inside the lifting port. A base plate 13 is set at the bottom of the limiting plate 12. The limiting plate 12 can move up and down within the lifting port. A support plate 14 is set on the side of the loading rack 1. A vertical rod 15 is set on the surface of the support plate 14. A limiting spring 16 is sleeved on the surface of the vertical rod 15. The base plate 13 is sleeved on the vertical rod 15. The base plate 13 can move up and down along the vertical rod 15. One end of the limiting spring 16 is fixedly connected to the bottom of the base plate 13, and the other end of the limiting spring 16 is fixedly connected to the surface of the support plate 14.

[0028] In use, the positioning frame 4 can first be positioned by the baffle 11 and the limiting plate 12 to prevent the positioning frame 4 from sliding on the surface of the loading rack 1. When the positioning frame 4 needs to be removed, first press the bottom plate 13 to move the bottom plate 13 down along the upright 15, so that the limiting plate 12 can move down and lose its limiting on the positioning frame 4, and the positioning frame 4 can slide off the loading rack 1. The setting of the limiting spring 16 also makes it convenient to automatically reset after pressing the bottom plate 13.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
