Description

Technical Field

[0001] This utility model relates to the field of swab flocking technology, specifically a clamping component for automatic flocking thread of swabs. Background Technology

[0002] In the field of medical testing and biological sampling, swabs are the core tool for collecting biological samples, and their production quality directly affects the accuracy and reliability of test results. With the development of automation technology, automated flocking lines for swabs have become the mainstream equipment for mass production. The clamping component, as a key structure in the automated flocking line, is responsible for stably fixing the swab array, which integrates multiple spaced swabs, during the flocking process. It is an important link in ensuring flocking accuracy and improving production efficiency.

[0003] Currently, the clamping mechanism of automatic flocking swab lines generally adopts a traditional snap-fit ​​structure, which involves directly inserting a swab holder integrating multiple swabs into a preset groove for positioning. However, in actual flocking operations, to ensure flocking uniformity and coverage, key processes such as sizing, flocking, and drying require continuous angle adjustment and rotation of the clamping device. Existing snap-fit ​​structures rely solely on the physical contact between the groove and the swab holder for fixation, lacking a targeted locking design. Centrifugal force and mechanical vibration during rotation can easily cause the swab holder to loosen or even detach within the groove, potentially damaging the swabs and contaminating the sample collection area. Therefore, this invention proposes a clamping component for automatic flocking swab lines to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping component for automatic flocking of swabs. By setting a rotatable rotating plate in conjunction with a drive component, the swab holder is stably pressed. A limiting component is used to precisely lock the drive component, so as to prevent the swab holder from loosening or falling off due to centrifugal force and mechanical vibration caused by angle adjustment and rotation operation during the flocking process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping assembly for an automatic flocking thread for a swab, comprising a support plate, a mounting post at the bottom of the support plate, a mounting groove on the support plate, a plurality of limiting grooves in the mounting groove, and a rotating plate rotatably disposed in the limiting groove; The support plate is provided with a drive assembly for driving the rotating plate to rotate, and the drive assembly is provided with a limit assembly for locking the drive assembly. The drive assembly includes a long rotating shaft that passes through multiple limiting slots and is fixedly connected to a rotating plate. A gear is fixed to the end of the long rotating shaft, and a toothed plate that is slidably connected to a support plate meshes with the gear.

[0006] Preferably, the support plate is provided with a protective box, and the toothed plate is slidably connected inside the protective box with one end slidably extending out of the protective box.

[0007] Preferably, the limiting component includes a fixed box disposed on the protective box, an insert block disposed inside the fixed box, a sliding rod fixedly connected to the insert block, a connecting plate disposed at the end of the sliding rod, and a return spring sleeved on the sliding rod.

[0008] Preferably, the toothed plate has a first slot and a second slot, and the insert can be inserted into the first slot or the second slot to lock the position of the toothed plate.

[0009] Preferably, the two ends of the reset spring abut against the insert block and the inner wall of the fixing box, respectively.

[0010] Preferably, when the insert is inserted into the second slot, the gear and the rotating shaft remain stationary, and the rotating plate is perpendicular to the support plate.

[0011] Preferably, when the toothed plate slides, the long shaft is rotated by a gear, so that the rotating plate can switch from a vertical state to a horizontal state; When the rotating plate is in a horizontal position, the first slot and the insert block are vertically aligned, and the insert block can be inserted into the first slot to lock the position of the toothed plate.

[0012] Preferably, when the rotating plate is in a horizontal state, its lower surface abuts against the upper surface of the swab holder.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The rotating plate is driven to rotate by the long shaft in the drive assembly. When the rotating plate switches to a horizontal position, its lower surface can tightly abut against the upper surface of the swab holder. Multiple rotating plates are precisely distributed between every two adjacent swabs, forming a targeted pressing structure. Combined with the locking design of the insert block in the limiting assembly, which inserts into the first slot, the swab holder can be effectively prevented from loosening or falling off due to centrifugal force and mechanical vibration caused by angle adjustment and rotation during the flocking process. This solves the problem of the lack of a reliable locking mechanism in traditional snap-fit ​​structures and ensures the stability of the swab production process. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Please see Figures 1 to 6 This utility model provides a technical solution: a clamping assembly for automatic flocking thread of a swab. The support plate 1 is made of high-strength engineering plastic and processed by injection molding. The overall structure is lightweight and has sufficient load-bearing strength. The mounting column 8 at the bottom is integrally injection molded with the support plate 1. The mounting column 8 is provided with threaded holes, which can be stably connected to the flocking thread frame by bolts, thus fixing the entire clamping assembly on the production equipment.

[0023] The mounting groove 2 on the support plate 1 is integrally injection molded along its length. The width of the groove is matched with the width of the swab row seat 5, which plays a preliminary positioning role for the swab row seat 5. The limiting grooves 3 are evenly distributed on both sides of the inner wall of the mounting groove 2 and are integrally injection molded with the support plate 1. The spacing between adjacent limiting grooves 3 is consistent with the spacing between adjacent swabs 6, providing precise space for the installation and operation of the rotating plate 4.

[0024] The rotating plate 4 is driven to rotate by the rotating shaft 71 in the drive assembly 7. When the rotating plate 4 switches to the horizontal state, its lower surface can tightly abut against the upper surface of the swab holder 5, and multiple rotating plates 4 are precisely distributed between every two adjacent swabs 6 to form a targeted pressing structure. With the locking design of the insert block 92 in the limiting assembly 9 inserting into the first slot 96, the swab holder 5 can be effectively prevented from loosening or falling off due to centrifugal force and mechanical vibration caused by angle adjustment and rotation operation during the flocking process. This solves the problem of the lack of a reliable locking mechanism in the traditional snap-fit ​​structure and ensures the stability of the swab 6 production process.

[0025] like Figure 3 As shown, the rotating plate 4 is made of wear-resistant hard plastic injection molding, which has a certain structural strength and can avoid scratching the swab. The rotating long shaft 71 and the rotating plate 4 are integrally formed by injection molding, ensuring that the rotating long shaft 71 can drive the rotating plate 4 to rotate synchronously when it rotates. The rotating long shaft 71 rotates in the limiting groove 3 through the bearing. One end of the rotating long shaft 71 extends to the outside of the support plate 1, and the end is fixed to the plastic gear 72 by hot pressing. The inner wall of the gear 72 is provided with a spline groove that matches the end of the rotating long shaft 71. After hot pressing, a reliable power transmission structure is formed.

[0026] The protective box 74 is made of plastic injection molding and is fixed to the side of the support plate 1 by self-tapping screws. The screws pass through the mounting ears of the protective box 74 and are threaded to the screw posts of the support plate 1, which protects the meshing structure of the toothed plate 73 and gear 72 inside. The protective box 74 has a guide groove that matches the toothed plate 73. The toothed plate 73 is made of wear-resistant hard plastic injection molding, is embedded in the guide groove and can slide along the groove. A gap is reserved between the guide groove and the toothed plate 73 to ensure the smoothness of the sliding process of the toothed plate 73. One side of the toothed plate 73 is fully engaged with the gear 72, and the other side slides to the outside of the protective box 74 and is integrally injection molded with the fixing block 98, which makes it convenient for the operator to move the toothed plate 73 by pushing the fixing block 98.

[0027] like Figure 4 as well as Figure 5 As shown, the fixing box 91 of the limiting component 9 is made of plastic injection molding and is fixed to the top of the protective box 74 by self-tapping screws. The screws pass through the mounting holes at the bottom of the fixing box 91 and connect with the pre-set screw holes in the protective box 74. The interior of the fixing box 91 is hollow, providing space for the sliding of the insert block 92. The insert block 92 is made of plastic injection molding and is slidably set inside the fixing box 91. It matches the shape of the first slot 96 and the second slot 97 to ensure that the insert block 92 can be smoothly inserted into the slot to achieve locking. One end of the sliding rod 93 is integrally formed with the insert block 92 by injection molding, and the other end passes through the through hole at the top of the fixing box 91 and is fixedly connected to the connecting plate 94 by bolts. The operator can move the plug 92 by pulling the connecting plate 94. The return spring 95 is made of stainless steel and is sleeved in the section of the sliding rod 93 located inside the fixed box 91. Its two ends are in close contact with the upper surface of the plug 92 and the inner wall of the fixed box 91, respectively. It can provide a return force after the plug 92 moves. The inner wall of the fixed box 91 has a pre-set spring positioning boss to prevent the return spring 95 from shifting during the extension and retraction process.

[0028] In the initial state, the reset spring 95 is in a naturally extended state, and the insert block 92 is inserted into the second slot 97 under the elastic force of the reset spring 95. At this time, the toothed plate 73 is in the initial position, the gear 72 and the rotating long shaft 71 do not rotate, and the rotating plate 4 is in a vertical state, perpendicular to the opening direction of the mounting slot 2, which facilitates the insertion of the swab holder 5.

[0029] When swabs need to be installed for flocking, the operator first aligns the swab holder 5 with the mounting groove 2, ensuring that the bottom of the swab holder 5 is accurately inserted into the mounting groove 2, completing the initial positioning. Then, the connecting plate 94 is pulled upwards, causing the sliding rod 93 to move upwards. The sliding rod 93 causes the insert block 92 to gradually move out of the second slot 97. During this process, the insert block 92 compresses the return spring 95, allowing the return spring 95 to store elastic potential energy.

[0030] Subsequently, the operator pushes the fixing block 98, which causes the toothed plate 73 to slide along the guide groove of the protective box 74. Since the toothed plate 73 meshes with the gear 72, the sliding of the toothed plate 73 causes the gear 72 to rotate. The gear 72, through the rotating shaft 71, causes the rotating plate 4 to rotate around the axis of the rotating shaft 71 within the limiting groove 3. As the toothed plate 73 continues to slide, the rotating plate 4 gradually changes from a vertical state to a horizontal state.

[0031] When the rotating plate 4 rotates to a horizontal position, its lower surface presses tightly against the upper surface of the swab holder 5, and the multiple rotating plates 4 are precisely positioned above the gap between each pair of swabs 6, forming a stable clamping force on the swab holder 5. At this time, the first slot 96 on the toothed plate 73 moves directly below the insert block 92. The operator releases the connecting plate 94, the return spring 95 releases its elastic potential energy, and pushes the insert block 92 downward, so that the insert block 92 is accurately inserted into the first slot 96, thereby locking the position of the toothed plate 73 and preventing the toothed plate 73 from sliding in subsequent operations, ensuring that the clamping state of the rotating plate 4 on the swab holder 5 is stable and reliable.

[0032] After the flocking operation is completed, when it is necessary to remove the swab holder 5, the operator pulls the connecting plate 94 upwards again, causing the insert 92 to move out of the first slot 96 and releasing the lock on the toothed plate 73. Then, the fixing block 98 is pushed in the opposite direction, causing the toothed plate 73 to slide in the opposite direction, and the gear 72 rotates in the opposite direction, driving the rotating plate 4 from the horizontal position back to the vertical position through the rotation of the long shaft 71. When the rotating plate 4 returns to the vertical position, the second slot 97 on the toothed plate 73 moves to directly below the insert 92. The connecting plate 94 is released, and the insert 92 is inserted into the second slot 97 under the action of the return spring 95, completing the reset. At this time, the operator can easily remove the swab holder 5 from the mounting slot 2.
