Description

Technical Field

[0001] This utility model relates to the field of medical cotton swab production and processing technology, and in particular to a cotton swab stick fixed-distance cutting device for dust-free cotton swab production. Background Technology

[0002] In modern medicine and daily life, cleanroom swabs are widely used, and their quality directly affects their effectiveness and safety. With the increasing market demand for cleanroom swabs, the performance requirements for swab production equipment, especially swab stick cutting equipment, are also rising.

[0003] Traditional cotton swab cutting equipment has several drawbacks. Regarding distance control, early equipment often used simple mechanical positioning or manual measurement, making it difficult to guarantee the accuracy of each cut. This resulted in inconsistent swab lengths, affecting the overall product quality and subsequent use. In terms of cutting stability, some equipment relied on simple slide rails or chain drives for the blade holder movement, which is prone to shaking and jamming during the cutting process. This not only reduces cutting efficiency but may also cause uneven cut surfaces, affecting product quality.

[0004] In terms of automation, some traditional equipment relies on a lot of manual operation. From the placement and movement of cotton swabs to the collection after cutting, manual intervention is required. This not only consumes labor costs, but also has low production efficiency and is difficult to meet the needs of large-scale production.

[0005] Therefore, those skilled in the art have provided a cotton swab cutting device for dust-free cotton swab production at a fixed distance to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a distance-fixed cutting device for cotton swab production in the form of a dust-free cotton swab. To achieve the above objective, this utility model provides the following technical solution: a threaded connection between a lead screw and a slider is used, along with a high-precision driver, so that the moving placement seat can achieve precise distance movement, ensuring a high degree of consistency in the cutting length of the cotton swab and significantly improving product quality.

[0007] Preferably, the tool holder utilizes the meshing transmission of an L-shaped movable block, a rack, and transmission gears to achieve smooth reciprocating linear motion during cutting. Combined with the cutting tool fixed to the tool holder, this effectively prevents jamming and deviation during cutting, greatly improving cutting efficiency and quality.

[0008] Preferably, the entire process, from fixing and moving the cotton swabs at a fixed distance to cutting and finally collecting the finished product, is completed collaboratively by automated components. An electric cylinder automatically controls the clamping mechanism to fix the cotton swabs, a drive motor automatically moves the cutter holder to cut, and a motor automatically drives the oscillating pusher to collect the finished product, significantly reducing manual intervention, lowering labor costs, and improving production efficiency.

[0009] Preferably, the equipment has a compact and reasonable structure, with the chassis integrating multiple components such as the collection tank and workbench, and the connection and transmission between the components are ingeniously designed. This compact layout not only saves space but also facilitates the installation, maintenance, and daily operation of the equipment, greatly enhancing its practicality and economy compared to existing equipment with complex and loose structures.

[0010] Preferably, a protective component is installed on the outer wall of the output shaft, which can effectively prevent operators from accidentally contacting the rotating parts, reduce the risk of safety accidents, and provide a reliable guarantee for safe production.

[0011] Preferably, the clamping member matches the placement groove, and the oscillating pusher matches the placement groove.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, each step, from fixing the cotton swab, moving it at a fixed distance, cutting it, to pushing and collecting the material, involves corresponding automated components working in concert. For example, the electric cylinder automatically controls the clamping component to fix the cotton swab, the drive motor automatically drives the cutter to cut, and the motor automatically drives the swinging pusher to collect the finished product, greatly reducing manual intervention, improving production efficiency, and lowering labor costs.

[0014] 2. In this utility model, the tool holder is driven by the meshing of the L-shaped movable block, rack and transmission gear, which makes the reciprocating linear motion of the tool holder during cutting more stable. Combined with the cutting tool fixed on the tool holder, it can achieve more stable and efficient cutting and reduce problems such as jamming and deviation during the cutting process.

[0015] 3. In this utility model, the threaded connection between the lead screw and the slider, combined with the precise control of the driver, enables extremely precise fixed-distance movement of the moving placement seat, ensuring that the cutting length error of each cotton swab is minimal, greatly improving the consistency and quality of the product.

[0023] Reference Figure 1 — Figure 5This invention relates to a device for cutting cotton swabs at a fixed distance in the production of dust-free cotton swabs. The purpose of this invention is to address the shortcomings of existing technologies by providing such a device. To achieve the above objective, this invention provides the following technical solution: It includes a housing 1. A collection groove 9 is installed at the middle position of the top of the rear side wall of the housing 1. A workbench 2 is installed at the middle position of the top of the housing 1. A sliding groove 6 is located at the middle position of the top of the workbench 2. A lead screw 7 is rotatably connected to the inner side wall of the sliding groove 6. A slider is threadedly connected to the outer side wall of the lead screw 7. The slider is slidably connected to the middle position of the inner side wall of the sliding groove 6. A movable placement seat 3 is installed at the middle position of the top of the slider. The top of the movable placement seat 3 has several openings. The cotton swabs are arranged in an array. A limiting cover 4 is installed above the movable placement seat 3. An electric cylinder 5 is installed at the top center of the limiting cover 4 near the front side. The output end of the electric cylinder 5 passes through the bottom of the limiting cover 4 and is connected to a lifting plate 16. Several clamping components 17 arranged in an array are installed at the bottom center of the lifting plate 16. A movable groove 22 is opened at the top center of the limiting cover 4 near the rear side. A swinging pusher 23 is rotatably connected to the inner wall of the movable groove 22. A motor 24 is connected to the input end of the swinging pusher 23. The motor 24 is installed on one side wall of the limiting cover 4. From fixing the cotton swabs, moving them at a fixed distance, cutting them, to pushing and collecting them, each step has corresponding automated components working together. For example, the electric cylinder 5 automatically controls the clamping components 17 to fix the cotton swabs, the drive motor 13 automatically drives the cutter to cut, and the motor 24 automatically drives the swinging pusher 23 to collect the finished product, which greatly reduces manual intervention, improves production efficiency, and reduces labor costs.

[0024] The input end of the lead screw 7 is connected to a driver. The driver is installed in the middle of the upper part of the inner side wall of the housing 1 near the rear. The clamping part 17 matches the placement groove, and the swing pusher part 23 matches the placement groove. The lead screw 7 and the slider are connected by a thread. With the high-precision driver, the moving placement seat 3 can achieve precise fixed-distance movement, ensuring the high consistency of the cotton swab cutting length and significantly improving product quality.

[0025] A tool holder 8 is slidably connected to the top center of the chassis 1 near the rear side. A cutting tool 15 is bolted to the inner wall of the tool holder 8 near the bottom. A drive motor 13 is installed on one side of the top of the chassis 1 near the front side. The output end of the drive motor 13 is connected to an output shaft 14. The other end of the output shaft 14 is connected to a first support base 11. The other end of the output shaft 14 is rotatably connected to the middle of the inner wall of a second support base 12. An L-shaped movable block 18 is installed on one side wall of the tool holder 8 near the lower end. A rack 21 is installed at the bottom of the L-shaped movable block 18. A transmission groove 20 is opened between the rack 21 and the L-shaped movable block 18. A transmission tooth 19 is rotatably connected to the inner wall of the transmission groove 20. The bottom of the transmission tooth 19 meshes with the top of the rack 21. The tool holder 8 can perform a smooth reciprocating linear motion during the cutting process by means of the meshing transmission of the L-shaped movable block 18, the rack 21, and the transmission tooth 19. The cutting tool 15, which is fixed on the tool holder 8, effectively avoids jamming and deviation during cutting, greatly improving cutting efficiency and quality.

[0026] A transmission gear 19 is installed on the outer wall of the output shaft 14 and located between the first support 11 and the worktable 2. A protective member 10 is sleeved on the outer wall of the output shaft 14 and outside the transmission gear 19. The protective member 10 on the outer wall of the output shaft 14 can effectively prevent operators from accidentally contacting the rotating parts, reduce the risk of safety accidents, and provide reliable protection for safe production.

[0027] Working principle: First, place the cotton swab to be cut in the placement slot at the top of the movable placement seat 3, then lower the limit cover plate 4, and push the lifting plate 16 through the electric cylinder 5 to lower the clamping part 17 and match it with the placement slot, thereby firmly fixing the cotton swab.

[0028] The input end of the lead screw 7 is connected to the driver, which is installed in the middle of the upper part of the inner side wall of the housing 1 near the rear. When the driver is started, it drives the lead screw 7 to rotate, causing the slider threadedly connected to the lead screw 7 to move in the slide groove 6, thereby driving the movable placement seat 3 to move according to the set distance to achieve fixed-distance positioning.

[0029] The drive motor 13 is installed on the top side of the chassis 1, near the front. Its output end is connected to the output shaft 14, which passes through the first support base 11 and is rotatably connected to the middle of the inner wall of the second support base 12. A transmission gear 19 is installed on the outer wall of the output shaft 14 between the first support base 11 and the worktable 2. The tool holder 8 is slidably connected to the top of the chassis 1, near the rear. An L-shaped movable block 18 is installed on the middle of one side wall of the tool holder 8, near the lower end. A rack 21 is installed at the bottom of the L-shaped movable block 18. The transmission gear 19 is rotatably connected in the transmission groove 20 between the L-shaped movable block 18 and the rack 21, and the bottom of the transmission gear 19 meshes with the top of the rack 21. When the drive motor 13 starts, it drives the output shaft 14 to rotate, which in turn drives the transmission gear 19 to rotate. The rotation of the transmission gear 19, through meshing with the rack 21, pushes the tool holder 8 to make reciprocating linear motion along the top of the housing 1. The cutting tool 15, which is bolted to the middle of the inner wall of the tool holder 8 near the bottom, can then cut the cotton swab after it has been positioned at a fixed distance.

[0030] After cutting, the motor 24 is installed on one side wall of the limit cover plate 4. The motor 24 is started, which drives the swing pusher 23 to rotate in the movable groove 22. The swing pusher 23 matches the placement groove and pushes the cut cotton swab out of the placement groove, so that it falls into the collection groove 9 installed at the middle position of the top of the rear side wall of the machine box 1, thus completing the entire fixed-distance cutting and collection process.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
