Technical Field

[0001] This utility model relates to the field of toothbrush manufacturing technology, specifically a multi-specification toothbrush clamping and positioning device. Background Technology

[0002] Toothbrush bristle implantation is a core process in toothbrush manufacturing. It involves using sophisticated automated equipment to accurately implant and fix clumps of bristles onto a pre-drilled toothbrush head plate. The mainstream technology uses tiny metal pins to clamp the bristle clumps in the middle within a mold and then bend and fix them into grooves on the back of the brush head.

[0003] In the prior art, the authorized announcement number is CN113876112A, which discloses a high-efficiency toothbrush bristle implantation device, including an operating table, a central controller, a drilling station and a bristle implantation station. The output end of the drive motor under the operating table is provided with a turntable through a rotating shaft, and a plurality of first rectangular through slots and second rectangular through slots are arranged in sequence with the center of the turntable as the center.

[0004] After the toothbrush handle is fixed in place, it can be rotated by a turntable. This accurately moves the toothbrush handle to the predetermined position below the bristle implantation head, preparing it for subsequent bristle implantation. Because different types of toothbrush products have different dimensions, the length, diameter, and other parameters of the toothbrush handle will vary, which places higher demands on the positioning device. To meet the production needs of toothbrush handles of different specifications, a multi-specification toothbrush clamping and positioning device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-specification toothbrush clamping and positioning device to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-specification toothbrush clamping and positioning device, comprising a turntable, a device notch on the turntable, a housing fixedly installed at the device notch, a base fixedly installed inside the housing, a clamping mechanism installed at one end of the base, the clamping mechanism comprising two mechanism housings fixedly installed on the base, a first guide rod slidably installed inside the two mechanism housings, a clamping plate fixedly installed at the end of the first guide rod, a V-shaped groove on the clamping plate, a thrust spring sleeved on the first guide rod, and a positioning mechanism at the other end of the base.

[0007] Preferably, the clamping mechanism further includes a movable shaft rotatably mounted on the bottom of the clamping plate, a guide roller rotatably mounted on the movable shaft, and a sliding groove provided on the base.

[0008] Preferably, the bottom of the clamping plate is provided with a rotating groove, and the movable shaft is rotatably mounted on the bottom of the clamping plate through the rotating groove.

[0009] Preferably, the movable shaft is slidably mounted on the base via a slide groove, one end of the thrust spring is connected to the clamping plate, the other end of the thrust spring is connected to one end of the mechanism housing, and the clamping plate is slidably mounted inside the mechanism housing via a first guide rod.

[0010] Preferably, the positioning mechanism includes a cylinder fixedly installed inside the housing and a second guide rod slidably installed on the base. A pressure block is fixedly installed at the end of the second guide rod, and a return spring is sleeved on the second guide rod. A drive rod is fixedly installed at the output end of the cylinder, and a top block is fixedly installed on the drive rod. The end of the drive rod is fixedly installed on a trapezoidal plate.

[0011] Preferably, the base has a sliding hole, and the second guide rod is slidably mounted on the base through the sliding hole.

[0012] Preferably, the base has a sliding sleeve at the bottom, and the drive rod is slidably mounted on the bottom of the base through the sliding sleeve.

[0013] Preferably, the top block is movably mounted on one side of the pressure block via a drive rod, one end of the return spring is connected to the pressure block, and the other end of the return spring is connected to the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, the trapezoidal plate positioned between the two guide rollers can expand the clamping plates, thus eliminating obstructions on the base. Toothbrush heads of different sizes can be placed on the base. After the toothbrush head is placed on the base, the cylinder can be extended. When the cylinder extends, the trapezoidal plate moves forward, causing it to separate from the guide rollers. After the trapezoidal plate separates from the guide rollers, the thrust spring causes the two clamping plates to move towards each other, clamping them onto the neck of the toothbrush handle, thereby achieving initial positioning of the toothbrush handle.

[0015] 2. In this application, when the cylinder extends continuously, it drives the top block to move forward. The top block moves forward, which in turn causes the pressure block to move forward, making it tightly fit against the brush head, thereby securing toothbrush handles of different sizes to the base. At the same time, when the cylinder retracts, the return spring pulls the pressure block back to its original position, and the trapezoidal plate moves between the two guide rollers, thereby releasing the locking state of the toothbrush handle and facilitating the unloading operation of the toothbrush handle.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a multi-specification toothbrush clamping and positioning device, including a turntable 1, a device notch 2 on the turntable 1, a housing 3 fixedly installed at the device notch 2, a base 4 fixedly installed inside the housing 3, a clamping mechanism 5 installed at one end of the base 4, and a positioning mechanism 6 provided at the other end of the base 4.

[0020] Specifically, through the coordinated operation of the clamping mechanism 5 and the positioning mechanism 6, toothbrushes of different specifications and sizes can be effectively fixed and securely mounted on the turntable 1. The turntable 1 can drive the toothbrush handles fixed on it to rotate stably, thereby accurately conveying the toothbrush handles to the preset bristle implantation station. This provides a reliable positioning reference and operating conditions for subsequent efficient bristle implantation operations, enabling the automation of key processes in toothbrush production.

[0021] Example 2: Figure 2 and Figure 3 As shown, the clamping mechanism 5 includes two mechanism housings 501 fixedly installed on the base 4. A first guide rod 505 is slidably installed inside the two mechanism housings 501. A clamping plate 502 is fixedly installed at the end of the first guide rod 505. A V-shaped groove 503 is opened on the clamping plate 502. A thrust spring 504 is sleeved on the first guide rod 505. The clamping mechanism 5 also includes a movable shaft 507 rotatably installed at the bottom of the clamping plate 502. A guide roller 506 is rotatably installed on the movable shaft 507. A sliding groove 401 is opened on the base 4. A rotating groove is opened at the bottom of the clamping plate 502. The movable shaft 507 is rotatably installed at the bottom of the clamping plate 502 through the rotating groove.

[0022] Specifically, when cylinder 601 retracts, trapezoidal plate 605 is positioned between the two guide rollers 506. Located between the two guide rollers 506, trapezoidal plate 605 can open clamping plate 502, ensuring no obstructions on base 4. Toothbrush heads of different sizes can be placed on base 4. After the toothbrush head is placed on base 4, cylinder 601 can be extended. When cylinder 601 extends, trapezoidal plate 605 moves forward, separating from guide rollers 506. After separation, thrust spring 504 causes the two clamping plates 502 to move towards each other, clamping the toothbrush handle neck and achieving initial positioning of the toothbrush handle.

[0023] Example 3: Figure 2 and Figure 4 As shown, the positioning mechanism 6 includes a cylinder 601 fixedly installed inside the housing 3 and a second guide rod 606 slidably installed on the base 4. A pressure block 604 is fixedly installed at the end of the second guide rod 606, and a return spring 607 is sleeved on the second guide rod 606. A drive rod 602 is fixedly installed at the output end of the cylinder 601, and a top block 603 is fixedly installed on the drive rod 602. The end of the drive rod 602 is fixedly installed on a trapezoidal plate 605. A sliding hole is provided on the base 4, and the second guide rod 606 is slidably installed on the base 4 through the sliding hole. A sliding sleeve is provided at the bottom of the base 4, and the drive rod 602 is slidably installed on the bottom of the base 4 through the sliding sleeve.

[0024] Specifically, as the cylinder 601 extends continuously, it drives the top block 603 to move forward. After the top block 603 moves forward, it drives the pressure block 604 to move forward, so that the pressure block 604 presses tightly against the brush head, thereby fixing the toothbrush handle to the base 4.

[0025] At the same time, when the cylinder 601 retracts, the return spring 607 will drive the pressure block 604 to reset, and the trapezoidal plate 605 will move between the two guide rollers 506, thereby releasing the lock on the toothbrush handle and making it easier to remove the toothbrush handle.

[0026] Working principle: When cylinder 601 retracts, trapezoidal plate 605 is positioned between two guide rollers 506. Located between the two guide rollers 506, trapezoidal plate 605 can open clamping plate 502, ensuring no obstructions on base 4. Toothbrush heads of different sizes can be placed on base 4. After the toothbrush head is placed on base 4, cylinder 601 can be extended. When cylinder 601 extends, trapezoidal plate 605 moves forward, separating from guide rollers 506. After separation, thrust spring 504 causes the two clamping plates 502 to move towards each other, clamping the toothbrush handle neck and achieving initial positioning of the toothbrush handle. Then, cylinder 601 extends further, which drives top block 603 forward. This forward movement of top block 603 then drives pressure block 604 forward, pressing it firmly against the brush head and fixing the toothbrush handle to the base 4. Simultaneously, retracting cylinder 601 causes return spring 607 to reset pressure block 604, and trapezoidal plate 605 moves between the two guide rollers 506, releasing the toothbrush handle from its lock and facilitating its removal. After fixing the toothbrush handle to the base 4, the turntable 1 can rotate it, transferring the toothbrush handle to the bristle-attaching station for bristle-attaching operations.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
