Description

Technical Field

[0001] The utility model belongs to the technical field of silk screen tooling, in particular to a silk screen tooling for processing circuit breakers. Background Art

[0002] Screen printing tooling refers to the auxiliary tools and equipment used in the screen printing process, which help improve printing efficiency and quality. Screen printing tooling includes but is not limited to screen printing machines, screens, scrapers, inks, substrates, etc. The selection and use of screen printing tooling has a vital impact on the screen printing effect. Therefore, it can be seen that the existing screen printing tooling basically meets people's usage needs, but the following problems still exist.

[0003] When the operator is in the process of silk screen printing, the operator places the silk screen screen on the outer surface of the circuit breaker, and then the operator places the paint in the silk screen screen, and then the operator uses a paint scraper to scrape the paint, thereby silk screen printing on the surface of the circuit breaker. However, when the paint scraper is scraping the paint, the operator needs to hold the paint scraper at a certain angle to the silk screen screen to ensure that the paint scraper can print the paint on the surface of the circuit breaker. However, during the silk screen printing process, the operator may not be able to ensure that the angle between the paint scraper and the silk screen screen is the perfect scraping angle, which may cause the operator to be inconvenient when scraping the paint. For this reason, we propose a silk screen tooling for circuit breaker processing. Utility Model Content

[0004] The utility model provides a screen printing tool for circuit breaker processing. The operator pushes a rotating block, which drives a scraper to move. Then the operator screws a nut, which is threadedly matched with a threaded rod to fix the rotating block between two groups of fixed blocks, thereby fixing the angle between the scraper and the screen printing frame, and increasing the stability of the operator when pulling the scraper to scrape paint.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a silk screen tooling for circuit breaker processing, comprising a silk screen frame, wherein fixed plates are symmetrically provided on both sides of the silk screen frame, and the fixed plates are slidingly connected to the silk screen frame, support rods are fixed on the surfaces of the fixed plates, and mounting blocks are slidingly connected to the ends of the support rods, and fixed blocks are fixed to the ends of the mounting blocks, a rotating block is provided between the two groups of the fixed blocks, and threaded rods passing through one side of the fixed block are fixed to the ends of the rotating blocks on both sides, nuts are threadedly installed on the surface of the threaded rods, and a scraper inserted into the silk screen frame is fixed on the surface of the rotating block.

[0006] Furthermore, spring grooves are provided around the fixed block, and a pull rod is passed through the middle of the spring groove. Positioning blocks and pull rings are fixed to the two side ends of the pull rod respectively. The surface of the pull rod is wrapped with springs that respectively abut against the inner wall of the spring groove and the surface of the abutment block fixed on the pull rod. The surface of the positioning block is sleeved with a positioning groove provided on the rotating block.

[0007] Furthermore, the spring grooves are connected to the receiving grooves on the outer wall of the fixed block near the rotating block, and the receiving grooves are all configured as rectangular grooves, which match the rectangular blocks configured for the positioning blocks.

[0008] Furthermore, the receiving grooves are all arranged in an annular shape, and a plurality of groups of wave-shaped grooves are opened on the surface of the receiving grooves.

[0009] Furthermore, a traction rod is fixed on one side where the mounting block and the support rod are in contact with each other, and the surface of the traction rod is provided with a traction groove opened in the support rod, and a guide rod fixed on the inner wall of the traction groove passes through the middle of the traction rod.

[0010] Furthermore, a slider is fixed on one side of the fixed plate and the rotating block that are in contact with each other, and the surface of the slider is sleeved with a sliding groove provided on the silk screen frame.

[0011] Furthermore, screw blocks are symmetrically fixed on the surface of the nut, and arc-shaped grooves are formed at the ends of the screw blocks.

[0012] Furthermore, a support frame is fixed at the angle between the support rod and the fixed plate, and the support frame is triangular.

[0013] The beneficial effects of the utility model are:

[0014] 1. The screen printing tooling for circuit breaker processing is equipped with a rotating block, a fixed block, a threaded rod and a nut. When the operator pushes the rotating block, the rotating block drives the threaded rod to rotate in a circular through hole opened on one side of the fixed block where the threaded rod passes through, so that the rotating block drives the scraper to rotate between the two sets of fixed blocks. Then the operator screws the nut, which is threadedly engaged with the threaded rod to fix the position of the rotating block, thereby adjusting the angle between the scraper and the screen printing frame, and increasing the stability of the operator pulling the scraper to scrape the paint.

[0015] 2. The silk-screen tooling for circuit breaker processing is provided with a pull ring, a pull rod, a positioning block and a positioning groove. When the operator pulls the pull ring, the pull ring drives the positioning block to move through the pull rod, so that the positioning block is moved out of the positioning groove. After the positioning block and the positioning groove no longer restrict the fixed block and the rotating block, the rotating block can be rotated between the two groups of fixed blocks. After the positioning block is inserted into the positioning groove, the positioning block and the positioning groove restrict the rotating block, so that the rotating block cannot rotate between the two groups of fixed blocks. This facilitates pre-positioning of the rotating block when fixing it, and improves the convenience of the operator in fixing the rotating block. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] Example:

[0024] See also Figure 1 - Figure 4A screen printing tool for circuit breaker processing includes a screen printing frame 1, fixed plates 7 are symmetrically provided on both sides of the screen printing frame 1, and the fixed plates 7 are slidably connected to the screen printing frame 1. A slider 3 is fixed on the side where the fixed plate 7 and the rotating block 10 are in contact with each other, and the surface of the slider 3 is provided with a slide groove 4 opened on the screen printing frame 1. A support rod 5 is fixed on the surface of the fixed plate 7, and the end of the support rod 5 is slidably connected to the mounting block 11. A traction rod 24 is fixed on the side where the mounting block 11 and the support rod 5 are in contact with each other, and the surface of the traction rod 24 is provided with a traction groove 22 opened in the support rod 5. A guide rod 23 fixed to the inner wall of the traction groove 22 is passed through the middle of the traction rod 24. , and a fixed block 9 is fixed to the end of the mounting block 11, a rotating block 10 is provided between the two groups of fixed blocks 9, and the ends of both sides of the rotating block 10 are fixed with a threaded rod 8 that passes through one side of the fixed block 9, and a nut 19 is threadedly installed on the surface of the threaded rod 8. A scraper 2 inserted into the screen printing frame 1 is fixed on the surface of the rotating block 10. When the operator needs to adjust the angle between the scraper 2 and the screen printing frame 1, the operator first screws the nut 19 to make the nut 19 threadedly matched with the threaded rod 8. After the nut 19 is threadedly matched with the threaded rod 8, the nut 19 no longer squeezes the rotating block 10, and the operator pushes the scraper 2, and the scraper 2 drives the rotating block 10 to rotate between the two groups of fixed blocks 9, so that the scraper The plate 2 slides in the screen printing frame 1 to adjust the angle between the scraper 2 and the screen printing frame 1. Then the operator takes the nut 19 again so that the nut 19 is no longer threaded with the threaded rod 8. The operator fixes the rotating block 10 between the two sets of fixing blocks 9 again, thereby fixing the position of the scraper 2, making it convenient to fix the angle between the scraper 2 and the screen printing frame 1. Then the operator pulls the rotating block 10, and the rotating block 10 drives the traction rod 24 to move through the mounting block 11. The traction rod 24 drives the support rod 5 to move through the traction groove 22. The support rod 5 drives the slider 3 to slide in the slide groove 4, so that the rotating block 10 drives the scraper 2 to slide in the screen printing frame 1 , and when the operator needs to pull the rotary block 10 back, the operator pulls the rotary block 10, the rotary block 10 drives the mounting block 11 to move, and the mounting block 11 drives the traction rod 24 to slide in the traction groove 22, and the waist-shaped hole opened in the middle of the traction rod 24 slides on the surface of the guide rod 23 set to a cylindrical shape, and the waist-shaped hole opened in the middle of the traction rod 24 is demarcated on the surface of the guide rod 23. The guide rod 23 restricts the traction rod 24 to prevent the traction rod 24 from moving out of the traction groove 22, and the rotary block 10 drives the scraper 2 to separate from the screen printing frame 1 to prevent the paint attached to the surface of the scraper 2 from scraping the surface of the screen printing frame 1 again when the scraper 2 moves back.

[0025] In other embodiments, spring grooves 16 are provided on all sides of the fixed block 9, and a pull rod 17 is passed through the middle of the spring groove 16. Positioning blocks 13 and pull rings 20 are fixed to the two side ends of the pull rod 17 respectively. The surface of the pull rod 17 is wrapped with springs 21 that respectively abut against the inner wall of the spring groove 16 and the surface of the block 15 fixed on the pull rod 17. The surface of the positioning block 13 is sleeved with a positioning groove 14 provided on the rotating block 10. When the operator adjusts the position of the scraper 2 and rotates the rotating block 10, the operator first pulls the receiving groove 12. The receiving groove 12 drives the block 15 to slide in the spring groove 16 through the pull rod 17, and when the block 15 slides in the spring groove 16, the block 15 squeezes the spring 21, causing the spring 21 to undergo elastic deformation. After the change, the spring 21 avoids the resisting block 15, so that the pull rod 17 drives the positioning block 13 to move out of the receiving groove 12. After the positioning block 13 and the positioning groove 14 no longer fix the rotating block 10, the operator pushes the rotating block 10 to rotate, and when the rotating block 10 no longer rotates, the operator releases the pull ring 20. After the pull ring 20 no longer squeezes the spring 21 through the pull rod 17, the elastic deformation of the spring 21 is restored, and the spring 21 pushes the pull rod 17 to move. The pull rod 17 drives the positioning block 13 to move, so that the positioning block 13 is moved out of the receiving groove 12, and the positioning block 13 is inserted into the positioning groove 14, and the position of the rotating block 10 is pre-fixed to prevent the rotating block 10 from rotating arbitrarily between the two sets of fixed blocks 9 when the operator screws the nut 19 to threadably engage with the threaded rod 8.

[0026] In other embodiments, the spring groove 16 is connected to the side of the rotating block 10 with a receiving groove 12 opened on the outer wall of the fixed block 9, and the receiving groove 12 is set as a rectangular groove. The rectangular groove set in the receiving groove 12 matches the rectangular block set in the positioning block 13. By matching the rectangular groove set in the receiving groove 12 with the rectangular block set in the positioning block 13, the positioning block 13 can be moved into the receiving groove 12, so that the receiving groove 12 can accommodate the positioning block 13, so that after the positioning block 13 is moved out of the positioning groove 14, the positioning block 13 is accommodated in the receiving groove 12, and the positioning block 13 avoids the rotating block 10.

[0027] In other embodiments, the receiving grooves 12 are all configured to be annular, and a plurality of groups of wavy grooves are provided on the surface of the receiving grooves 12. By configuring the receiving grooves 12 to be annular, the receiving grooves 12 surround the nut 19, and a plurality of groups of wavy grooves are provided on the surface of the receiving grooves 12, thereby increasing the friction force of the operator's hand holding the surface of the receiving grooves 12 and improving the stability of the operator pulling the receiving grooves 12.

[0028] In other embodiments, the surface of the nut 19 is symmetrically fixed with a screw block 18, and the end of the screw block 18 is provided with an arc-shaped groove. When the operator screws the nut 19 to rotate it, the operator holds his hand on the surface of the screw block 18. When the operator holds his hand on the surface of the screw block 18, the arc-shaped groove on the surface of the screw block 18 is convenient for accommodating the operator's fingers, thereby increasing the comfort of the operator's fingers in screwing the screw block 18. Then the operator drives the nut 19 to rotate through the screw block 18, thereby improving the convenience of the operator in screwing the nut 19.

[0029] In other embodiments, a support frame 6 is fixed at the angle between the support rod 5 and the fixed plate 7, and the support frame 6 is triangular. The support frame 6 is fixed at the angle between the support rod 5 and the fixed plate 7 to form a triangle, so that the support frame 6 supports the angle between the support rod 5 and the fixed plate 7, increases the strength between the support rod 5 and the fixed plate 7, and improves the stability of the support rod 5 and the fixed plate 7 when in use.

[0030] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
