Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figures 1-5 This embodiment of the present invention provides a screen printing squeegee pressure regulating device, comprising:

[0028] The support mechanism 100 includes a mounting base 101, an adjustment component 102 disposed at the bottom of the mounting base 101, and a bracket 103 fixedly installed on the outside of the adjustment component 102;

[0029] The positioning mechanism 200 includes a lower plate 201 fixedly installed in the inner cavity of the bracket 103, an upper plate 202 snapped onto the top of the lower plate 201, and a fastener 203 disposed on the outside of the upper plate 202.

[0030] The layered structure of the lower plate 201 and the upper plate 202 facilitates the positioning and fixing of the scraper body 205. The fastener 203 further ensures the firmness of the connection between the upper plate 202 and the lower plate 201. When installing the scraper body 205, it can be easily placed in the positioning groove 204.

[0031] Specifically, the support mechanism 100 also includes an arc-shaped channel 104 opened on the outside of the bracket 103, a fastening bolt 105 movably installed in the inner cavity of the arc-shaped channel 104, a rotating shaft 106 hinged to the inner surface of the bracket 103, a plate 107 fixedly installed at the end of the rotating shaft 106, a sealing seat 108 fixedly installed on the top of the mounting base 101, and a drive motor 109 fixedly installed on the top of the sealing seat 108.

[0032] In this method, by loosening the fastening bolt 105, the angle of the positioning mechanism 200 within the arc-shaped channel 104 can be adjusted, and then the bolt 105 can be tightened to fix the position. This facilitates operation and improves the flexibility of the device. When the squeegee body 205 is subjected to uneven pressure, the plate 107 can rotate to a certain extent through the rotating shaft 106, thereby adjusting the contact angle between the squeegee body 205 and the screen, which helps to evenly distribute the pressure and improve the printing quality.

[0033] Furthermore, the adjustment assembly 102 includes a drive member 102a fixedly installed at the bottom of the mounting base 101, an electromagnetic guide rail 102b fixedly installed on the outside of the drive member 102a, and a drive sliding sleeve 102c movably sleeved on the outer surface of the electromagnetic guide rail 102b.

[0034] By adjusting the coordinated operation of the drive component 102a, electromagnetic guide rail 102b, and drive sleeve 102c in component 102, the up and down movement of the squeegee body 205 can be precisely controlled, thereby adjusting the pressure of the squeegee body 205 on the screen, which helps to adapt to different printing requirements, different ink thicknesses, screen mesh counts, and the fineness of the printed pattern.

[0035] Preferably, the fastener 203 includes a recess 203a that is engaged on the surface of the upper plate 202, a ring 203b that is fixedly installed at the bottom of the recess 203a, and a threaded rod 203c that is fixedly installed at the bottom of the ring 203b. The fastener 203 also includes a spring 203d that is sleeved on the outer surface of the threaded rod 203c, and a nut seat 203e that cooperates with the threaded rod 203c. The threaded rod 203c passes through the upper plate 202 to the outer side of the bottom of the lower plate 201. The threaded rod 203c is threadedly connected to the nut seat 203e. The upper plate 202 and the lower plate 201 are movably engaged.

[0036] The upper and lower plates are fixed by fasteners 203, so that the scraper body 205 is stably positioned in the device. The combination of the concave block 203a, ring 203b, threaded rod 203c, spring 203d and nut seat 203e in the fastener 203 allows the threaded rod 203c to pass through the upper plate 202 to the bottom outer side of the lower plate 201 and be threaded to the nut seat 203e. The elasticity of the spring 203d can ensure a firm connection while adapting to a certain degree of vibration or pressure change.

[0037] Furthermore, the positioning mechanism 200 also includes a positioning groove 204 formed between the upper plate 202 and the lower plate 201, and a scraper body 205 inserted into the cavity of the positioning groove 204.

[0038] The positioning groove 204 provides a precise installation position for the squeegee body 205, ensuring the positional accuracy of the squeegee body 205 during the printing process. This ensures that the contact angle and pressure distribution between the squeegee body 205 and the screen are uniform, improving the uniformity of ink transfer and thus improving printing quality.

[0039] In use, the mounting base 101 in the bearing mechanism 100 first provides a stable mounting foundation, the adjustment component 102 starts to work, the drive component 102a, the electromagnetic guide rail 102b and the drive sliding sleeve 102c work together to adjust the scraper to move up and down to control the pressure, the bracket 103 provides support and connection, the arc-shaped channel 104 and the fastening bolt 105 facilitate the adjustment of the component position, the rotating shaft 106 and the plate 107 assist in buffering or adjusting the contact angle during pressure adjustment, the sealing seat 108 protects the drive motor 109, and the motor provides power for adjustment;

[0040] The positioning mechanism 200 includes a lower plate 201 and a snap-fit ​​upper plate 202 for positioning the scraper body 205. The fastener 203 includes a recess 203a, a ring 203b, a threaded rod 203c, a spring 203d, and a nut seat 203e. The threaded rod 203c passes through the upper plate 202 and the lower plate 201 and is threadedly connected to the nut seat 203e. The elasticity of the spring 203d ensures a firm connection and adapts to vibration or pressure changes. After the scraper body 205 is placed in the positioning groove 204, the upper and lower plates are fixed by the fastener 203 to ensure the stable position of the scraper body 205.

[0041] In summary, the positioning mechanism 200 allows the squeegee body 205 to be conveniently placed in the positioning groove 204 during installation. Then, the upper plate 202 and the lower plate 201 are fixed by fasteners 203, so that the squeegee body 205 is stably positioned in the device. This enables quick disassembly and replacement of different types of squeegees. Furthermore, during the printing process, even if affected by squeegee pressure and equipment vibration, the position of the squeegee body 205 remains stable, thereby ensuring the accuracy and consistency of the printed pattern.
