Description

Technical Field

[0001] This utility model belongs to the field of cotton swab preparation technology, and in particular relates to a cotton swab head forming device for preparing dust-free cotton swabs. Background Technology

[0002] In high-end fields such as electronics manufacturing, biomedicine, and precision instruments, the demand for cleanroom swabs is increasing. These swabs not only require extremely high cleanliness but also stringent standards for the forming precision, structural regularity, and adhesion of the swab head. As the key component for cleanroom swabs to perform core functions such as cleaning and wiping, the forming quality of the swab head directly determines the product's performance. Deviations in the position of the swab head on the swab stick can lead to inaccurate wiping positioning; loose wrapping can cause fiber shedding and contaminate the work environment; and weak adhesion can easily result in the swab head falling off. All of these can cause serious consequences such as damage to precision components or distortion of experimental data. Therefore, achieving precise and regular forming of the swab head at specific locations on the swab stick has become a core technical challenge in the preparation of cleanroom swabs.

[0003] In the cotton swab forming process, existing cotton swabs vary in length, and the rotation and position adjustment mechanisms of existing devices are mostly independently controlled, making it difficult to achieve coordinated operation between the two. This results in insufficient stability of the cotton swab's posture during the cotton swab winding process. Some devices can only achieve a single rotation of the cotton swab, unable to adapt to changes in the winding tension of the cotton swab by fine-tuning the horizontal position. This easily leads to uneven winding and inconsistent density of the cotton swab, affecting the structural regularity of the cotton swab head and its wear resistance during use. At the same time, for cleanroom cotton swab preparation scenarios that require adhesive reinforcement, the insufficient rotational stability of the cotton swab in existing devices results in the glue not being evenly distributed on the surface of the cotton swab, and insufficient adhesion strength between the cotton swab and the cotton swab. This poses a risk of cotton head detachment during use and fails to meet the requirements of high-end cleanroom cotton swabs for service life. Therefore, a cotton swab head forming device for cleanroom cotton swab preparation is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a cotton swab head forming device for preparing dust-free cotton swabs. By setting an adapter component, specifically by activating a cylinder to drive the connecting bracket to move, during this process, a limiting plate drives the support frame to move forward, and the synchronously moving support frame adjusts the horizontal position of the cotton swab stick. When rolling the cotton, a motor drives the support frame to rotate, causing the cotton swab stick to rotate accordingly. This solves the problem in the cotton rolling process where, due to the varying lengths of existing cotton swab sticks and the fact that the existing devices often have independently controlled rotating and position-adjusting mechanisms, it is difficult to achieve coordinated operation between the two, resulting in unstable posture of the cotton swab stick during the cotton wrapping process. The existing devices suffer from insufficient stability. Some devices can only achieve a single rotation of the swab stick, and cannot adapt to changes in the winding tension of the cotton strip by fine-tuning the horizontal position. This easily leads to problems such as uneven winding and inconsistent density of the cotton strip, affecting the structural regularity of the cotton swab head and its wear resistance during use. At the same time, for the preparation of dust-free cotton swabs that require adhesive reinforcement, the existing devices suffer from insufficient stability of the swab stick rotation, resulting in the glue not being evenly distributed on the surface of the cotton stick. The adhesion strength between the cotton strip and the cotton stick is insufficient, and there is a risk of the cotton head falling off during use. This makes it difficult to meet the requirements of high-end fields for the service life of dust-free cotton swabs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] Furthermore, a number of clamping blocks are provided on the side of the partition away from the driven gear plate. The clamping blocks are arranged in two groups, and a connecting rod is fixedly connected between the two groups of clamping blocks. A sliding rod is fixedly connected to the back of the clamping blocks located on the back side.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5As shown, this utility model is a cotton swab head forming device for preparing dust-free cotton swabs, including a support device mounting plate 111 and a preparation mechanism 2. The preparation mechanism 2 is mounted on the mounting plate 111 and includes an adapter component 21 mounted on the mounting plate 111 and a clamping component 22 disposed on the front side of the mounting plate 111. The adapter component 21 includes a cylinder 212 fixed to the back side of the mounting plate 111. A support frame 211 is provided on the front side of the mounting plate 111. A limiting plate 216 is rotatably connected to the edge of the back side of the support frame 211. The side of the limiting plate 216 away from the support frame 211 is fixedly connected to the front output end of the cylinder 212. A clamping component is mounted on the side of the limiting plate 216 away from the support frame 211. The rotating component, the limiting plate 216, has several heat dissipation holes on the side away from the support frame 211. The starting cylinder 212 drives the connecting bracket 213 to move. During this process, the limiting plate 216 moves the support frame 211 forward, and the synchronously moving support frame 211 adjusts the horizontal position of the cotton swab. When rolling the cotton, the motor 215 drives the support frame 211 to rotate, causing the cotton swab to rotate accordingly. This dual adjustment precisely positions the cotton swab to the target position, ensuring the cotton strip is precisely wound around one end, achieving a tight and neat cotton head, even glue distribution, and strong adhesion, improving product performance and appearance quality. The mounting plate 111 has several guide rods 214 fixedly connected to its front side, and the outer surfaces of the guide rods 214 are slidably connected to the inner edge of the back side of the limiting plate 216. Several guide rods 214 are used to guide and limit the limiting disk 216. The clamping assembly 22 includes a second motor 221 disposed inside the cavity of the limiting disk 216. The front of the second motor 221 is fixedly connected to the back of the support frame 211. The back of the cavity of the support frame 211 is rotatably connected to a driven gear 223 via a pin. The outer surface of the driven gear 223 is meshed with a driving gear 224. The output end of the front of the second motor 221 is fixedly connected to the center of the driving gear 224 through the support frame 211 and a coupling. The second motor 221 provides power output for clamping and fixing the cotton swab. A partition 222 is provided on the front of the driven gear 223. The outer ring of the partition 222 is fixedly connected to the inner wall of the cavity of the support frame 211. The partition 222 has several curved grooves 226 inside, and several straight grooves 225 inside. The straight grooves 225 and the curved grooves 226 are respectively arranged correspondingly. Several clamping blocks 227 are arranged on the side of the partition 222 away from the driven gear 223. The clamping blocks 227 are arranged in two groups, and a connecting rod 228 is fixedly connected between the two groups of clamping blocks 227. The back of the clamping blocks 227 on the back side is fixedly connected to a sliding rod 210. The outer surface of the sliding rod 210 is slidably connected to the inside of the straight grooves 225 and the curved grooves 226 respectively. The straight grooves 225 provide a limiting and guiding function for the sliding rods 210. The front of the clamping blocks 227 on the front side is slidably connected to a slide rail 229.Several slide rails 229 are fixedly connected to the front side of the inner wall of the support frame 211 cavity on the side away from the clamping block 227. The slide rails 229 provide guidance and support for the clamping blocks 227 on the front. A circular hole is opened at the center of the front of the support frame 211. The starter motor 221 drives the drive gear 224 to rotate forward, which in turn drives the driven gear 223 to rotate. The arc groove 226 guides the slide rod 210 to converge inward along the straight groove 225. The connecting rod 228 synchronously drives the two sets of clamping blocks 227 to move towards each other. The slide rails 229 provide guidance and limit for the clamping blocks 227, realizing... Multiple sets of clamping blocks 227 provide adaptive clamping and fixation for the cotton swabs. This structure is compatible with cotton swabs of different diameters, offering strong versatility and low cost. The stable clamping system formed by the two sets of clamping blocks 227 effectively suppresses shaking during processing, enhances the tight and uniform forming effect of the cotton head during the rolling process, and improves product quality stability. The rotating component includes a motor 215 fixed to the side of the limiting plate 216 away from the support frame 211. The front output end of the motor 215 passes through the limiting plate 216 and is fixedly connected to the back of the support frame 211. The motor 215 provides power output for the rotation of the cotton swabs.

[0027] A specific application of this embodiment is as follows: In use, the cotton swab is first clamped and fixed by inserting it into the support frame 211. Then, the motor 221 is started to drive the drive gear 224 to rotate forward. During the rotation of the drive gear 224, the driven gear 223 is simultaneously driven to rotate. The driven gear 223, in turn, drives multiple sliding rods 210 to move through multiple arc grooves 226. The sliding rods 210 are then brought together by the limiting effect of the straight grooves 225. During this convergence, the back clamping block 227 moves synchronously. Simultaneously, during the movement of the back clamping block 227, the front clamping block 227 slides on its surface through the connecting rod 228. At the same time, the sliding rods 220... 10 slides inside the arc groove 226 and the straight groove 225, and the slide rail 229 guides and limits the movement trajectory of the connecting rod 228. When multiple connecting rods 228 converge, they achieve the effect of clamping and fixing the cotton swab. It can be used to clamp and fix cotton swabs of various diameters. There is no need to equip different forming devices for cotton swabs of different diameters, which reduces production costs and improves the versatility and flexibility of the equipment. At the same time, by clamping and fixing the cotton swab through two sets of connecting rods 228, the shaking or displacement of the cotton swab during processing can be effectively reduced, and the forming quality stability of the cotton swab head can be improved. For example, during the cotton rolling process, the cotton head can be wrapped more tightly and evenly, reducing the occurrence of loose cotton head or irregular shape.

[0028] Meanwhile, a position sensor is installed on the mounting plate 111 to detect the length of the cotton swab. The control system then activates cylinder 212 to move the connecting bracket 213. During the movement of the connecting bracket 213, the limiting plate 216 moves the support frame 211 forward. Simultaneously, as the limiting plate 216 moves, its back edge slides on the outer surface of multiple guide rods 214, providing stability to the movement trajectory of the limiting plate 216. The movement of the support frame 211 synchronously moves the cotton swab, adjusting its horizontal position. Furthermore, when rolling the cotton swab head, motor 215 is activated to move the support frame 211. The support frame 211 rotates, which in turn drives the cotton swab to rotate synchronously. By adjusting the horizontal position of the cotton swab and rotating it during cotton rolling, the cotton swab can be accurately delivered to the designated position, allowing the cotton swab head to be formed in a specific part of the cotton swab. For example, during cotton rolling, the cotton strip can be precisely wrapped around one end of the cotton swab, enhancing the positional accuracy of the cotton swab head. During the cotton swab head forming process, the rotation of the cotton swab can make the cotton strip evenly wrapped around its surface, forming a tight and regular cotton head, improving the performance and appearance quality of the cotton swab. If glue needs to be applied during the cotton rolling process, the rotation of the cotton swab helps the glue to be evenly distributed on its surface, making the adhesion between the cotton strip and the cotton swab stronger and reducing the possibility of the cotton head falling off.

[0029] It should be noted that the control of cylinder 212, motor 215, and motor 221 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLCs. The position sensor is a magnetic position sensor AS5048B, which is a high-performance magnetic sensor from Osram, featuring 14-bit resolution, a measurement accuracy of 0.5°, and an operating voltage of 3.3-5VDC. It is suitable for miniaturized device designs. Its advantage lies in non-contact measurement, which avoids the risk of contamination caused by direct contact with the cotton swab. Furthermore, its operating temperature range is -40℃ to 150℃, making it suitable for the temperature control environment of cleanrooms, especially for medical cotton swab production scenarios with extremely high cleanliness requirements.
