This invention, with its movable disc and clamping blocks, makes overall grinding more convenient.

[0004] Existing technologies often have the following drawbacks: during the needle production and grinding process, the use of grinding rollers to grind the needles can lead to residual needle debris on the surface of the grinding rollers, affecting the uniformity and efficiency of the grinding process.

[0005] Therefore, this utility model provides a uniform grinding device for needle production. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where grinding rollers for needles can lead to residual needle debris on the roller surface, affecting the uniformity and efficiency of the grinding process. Therefore, this invention proposes a uniform grinding device for needle production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a uniform grinding device for needle production, comprising an operating table, a clamping drive table fixedly connected to the upper surface of the operating table, two adjusting plates slidably connected to the side of the operating table near the clamping drive table, grinding rollers rotatably connected to the inner walls of the two adjusting plates, and a cleaning device provided on the side of the two adjusting plates that are far apart from each other. The cleaning device comprises two "L"-shaped plates, which are respectively fixedly connected to the side of the two adjusting plates that are far apart from each other. A scraper is fixedly connected to the side of the two "L"-shaped plates near the adjusting plates, and the scraper abuts against the grinding roller.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a uniform grinding device for needle production, including an operating table 1, a clamping drive table 4 fixedly connected to the upper surface of the operating table 1, two adjusting plates 2 slidably connected to the side of the operating table 1 near the clamping drive table 4, grinding rollers 3 rotatably connected to the inner walls of the two adjusting plates 2, a cleaning device 5 provided on the side of the two adjusting plates 2 that are far apart from each other, and a collection device 6 provided on the upper surface of the operating table 1.

[0031] The following section will describe the specific setup and function of the cleaning device 5 and the collection device 6.

[0032] Reference Figures 1-4 As shown in this embodiment: the cleaning device 5 includes two L-shaped plates 501, which are fixedly connected to the opposite sides of the two adjusting plates 2. A scraper 503 is fixedly connected to the side of each L-shaped plate 501 closest to the adjusting plate 2, and the scraper 503 abuts against the grinding roller 3. A brush 504 is fixedly connected to the side of each L-shaped plate 501 closest to the adjusting plate 2. During the grinding process of the grinding roller 3 on the needles, the scraper 503 and brush 504 can clean the needle debris remaining on the surface of the grinding roller 3. Two side plates 505 are fixedly connected to the opposite sides of the two adjusting plates 2, and a fixing rod 506 is fixedly connected to the side of the two side plates 505 closest to each other. The fixing rod 506 is installed on the side of the brush 504 closest to the operating table 1. The side plate 505 can be used to connect the fixing rod 506 and the adjusting plate 2. After the brush plate 504 is used, the fixing rod 506 can be used to promote the separation and falling off of the remaining needle debris on the brush plate 504.

[0033] Each of the two L-shaped plates 501 has a detachable collection box 502 installed on the side closest to the brush plate 504. Each of the two adjusting plates 2 has a sliding groove on the side furthest from each other. A slider 510 is slidably connected to the surface of the sliding groove on each of the two adjusting plates 2, and the slider 510 is fixedly connected to the L-shaped plate 501. The collection box 502 collects the needle debris cleaned by the brush plate 504. The slider 510 ensures a stable connection between the L-shaped plate 501 and the adjusting plate 2 while allowing the L-shaped plate 501 to move relative to the adjusting plate 2. A connecting block 507 is fixedly connected to the side of each adjusting plate 2 furthest from each other. An electric telescopic rod 508 is fixedly connected to the side of the connecting block 507 furthest from the adjusting plate 2. The output end of the electric telescopic rod 508 is fixedly connected to the L-shaped plate 501. A stabilizing plate 509 is fitted onto the surface of the electric telescopic rod 508, and the stabilizing plate 509 is fixedly connected to the L-shaped plate 501. The electric telescopic rod 508 can be used to control the position adjustment of the "L"-shaped plate 501. During the extension and retraction of the electric telescopic rod 508, the stabilizing plate 509 can improve its stability.

[0034] Reference Figure 2 and Figure 5 As shown, specifically, the collection device 6 includes a storage box 61, which is fixedly connected to the upper surface of the operating table 1. A sealing plate 65 is slidably connected to the inner wall of the storage box 61. The storage box 61 allows for the unified collection of polished needles, and the sealing plate 65 facilitates the opening and closing of the storage box 61, enabling the transfer of the needles inside. Two rotating rods 63 are rotatably connected to the inner wall of the storage box 61, and five baffles 64 are fixedly connected to the surface of each of the two rotating rods 63. The rotating rods 63 rotatably connected to the inner wall of the storage box 61 ensure that the baffles 64 can move in a circular motion relative to the storage box 61, thereby providing a buffering effect as the needles enter the storage box 61.

[0035] A control plate 66 is fixedly connected to the side of the sealing plate 65 away from the clamping drive stage 4. The control plate 66 is slidably connected to the inner wall of the storage box 61. A ramp 62 is fixedly connected to the inner wall of the storage box 61, with the side of the ramp 62 closer to the clamping drive stage 4 being higher than its opposite side. The control plate 66 allows for easy movement of the sealing plate 65, and the ramp 62 guides the needles inside the storage box 61 to exit the storage box 61.

[0036] Working principle: When the needle is polished using a uniform polishing device for needle production, the electric telescopic rod 508 on the connecting block 507 is activated, causing it to slide on the inner wall of the stabilizing plate 509, thereby pushing the "L"-shaped plate 501 to move. The movement of the "L"-shaped plate 501 causes the slider 510 to slide on the surface of the groove on the adjusting plate 2, while simultaneously moving the scraper 503 and the brush 504 closer to the polishing roller 3. This allows the needle debris on the surface of the polishing roller 3 to be cleaned during the rotation of the polishing roller 3. The cleaned debris falls into the collection box 502. After the polishing process is completed, the "L"-shaped plate 501 is moved away from the polishing roller 3 again by the electric telescopic rod 508. During this process, the brush 504 is separated from the remaining needle debris by the fixing rod 506 on the side plate 505. With the cleaning device 5, during the grinding process of the grinding roller 3, the scraper 503 and brush 504 can be used to clean the debris generated by grinding the needle on the surface of the grinding roller 3, so as to avoid the depressions on the surface of the grinding roller 3 being filled with needle debris, thereby maximizing the uniformity and efficiency of grinding the needle by the grinding roller 3.

[0037] After the needle is polished on the operating table 1, the clamping drive table 4 is used to control the needle to move away from the adjusting plate 2. When the needle moves above the storage box 61 and the clamping drive table 4 loses its clamping effect due to the movement of the needle, the needle falls into the storage box 61 under the action of gravity. The needle falls onto the surface of the baffle 64 on the rotating rod 63 and then enters the storage box 61 under the guidance of the baffle 64, thus realizing the collection of the needle. When it is necessary to transfer the needle in the storage box 61, the container storing the needle is placed on the side of the storage box 61 close to the control plate 66. The control plate 66 is used to move the sealing plate 65 away from the operating table 1 to release the sealing of the storage box 61. Thus, under the guidance of the inclined table 62, the needle can be transferred. With the collection device 6, the needles can be stored in a centralized manner in the storage box 61 after the needles have been polished, thereby reducing the repetitive collection work during the feeding process. At the same time, the rotating rod 63 and the baffle 64 can be used to block and buffer the falling needles, so as to avoid the needles from being bumped and damaged as much as possible.
