DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and implementation modes:

[0023] It should be noted that the interdental brush includes a brush handle and a brush head, wherein the brush handle includes a handle 101 and a connecting section, and the handle 101 and the connecting section are connected by a snap-in connection method. The existing connection method for the handle 101 and the connecting section is usually assembled by manual docking, and this assembly method is relatively inefficient. Therefore, it is necessary to propose a twisting mechanism for an interdental brush cap assembly machine, which is used to clamp the handle 101 part, thereby pushing the handle 101 to move toward the connecting section so that it docks with the connecting section, and rotating the handle 101 relative to the stationary connecting section for snap-in connection and fixing, thereby replacing manual labor to assemble the handle 101 and the connecting section, thereby improving the assembly efficiency of the brush handle, increasing the degree of automation and reducing labor costs.

[0024] like Figures 1 to 3 As shown, a material twisting mechanism for an interdental brush cap assembly machine includes a fixed plate 10, a driving member 20 and a sliding member 30. The fixed plate 10 is provided with a slide rail 11. The sliding member 30 is located above the slide rail 11 and is slidably connected to the slide rail 11. The driving member 20 is connected to one end of the fixed plate 10, and the driving member 20 is used to drive the sliding member 30 to move on the slide rail 11. In addition, it also includes a material twisting assembly 40, which is located above and connected to the sliding member 30. The material twisting assembly 40 includes a material twisting motor 41, a connecting member 42 and a clamping member 43. One end of the connecting member 42 is connected to the material twisting motor 41, and the other end is connected to the clamping member 43. The clamping member 43 is used to clamp the handle 101 of the interdental brush, wherein the material twisting motor 41 is used to drive the connecting member 42, the clamping member 43 and the handle 101 to rotate axially, and the driving member 20 is used to drive the material twisting assembly 40 and the sliding member 30 to reciprocate along the axial direction.

[0025] In this embodiment, the material twisting mechanism includes a fixed plate 10, a driving member 20, a sliding member 30 and a material twisting assembly 40. The lower end surface of the fixed plate 10 is connected and fixed with the assembly machine bolts, and the upper end surface is bolted with a slide rail 11. The sliding member 30 is slidably arranged on the slide rail 11. Specifically, the sliding member 30 is a sliding block provided with a slide groove adapted to the slide rail 11, wherein the driving member 20 is connected and fixed with one end of the fixed member, and the output end of the driving member 20 is connected with the sliding member 30. By controlling the driving member 20 to drive The sliding member 30 reciprocates along the direction of the slide rail 11. In addition, the twisting assembly 40 is connected and fixed to the sliding member 30, and moves along the axial direction of the slide rail 11 with the sliding member 30. Specifically, the twisting assembly 40 includes a twisting motor 41, a connecting member 42 and a clamping member 43, wherein the lower end surface of the twisting motor 41 is bolted and fixed to the upper end surface of the sliding member 30, the end of the twisting motor 41 away from the driving member 20 is bolted and fixed to one end of the connecting member 42, and the other end of the connecting member 42 is bolted and fixed to the clamping member 43. The connecting member 43 is connected and fixed, and the connecting member 42 is used to clamp and fix the handle 101. It should be noted that by controlling the driving member 20, the sliding member 30 and the twisting assembly 40 can be driven to reciprocate along the axial direction of the slide rail 11, thereby driving the clamping member 43 to approach the handle 101 and clamp the handle 101. In combination with controlling the twisting motor 41 to drive the connecting member 42 and the clamping member 43 to rotate along the axial direction, the handle 101 is driven to rotate, so that the handle 101 is fixed to the connecting member 42 fixed on the assembly machine. The connecting section is connected and fixed by snapping, that is, the utility model uses the structural arrangement of the fixed plate 10, the driving member 20, the sliding member 30, that is, the twisting assembly 40, to clamp the handle 101 on the conveyor belt of the assembly machine, so that the clamping member 43 moves forward to clamp the handle 101, and moves to the connecting section, and the handle 101 is rotated by the clamping of the twisting motor 41 and the connecting member 42 to be snap-connected with the connecting section, thereby replacing the manual assembly of the handle 101 and the connecting section, thereby improving the degree of automation and reducing the labor input cost.

[0026] It needs to be explained that the interdental brush cap assembly machine is provided with a conveying mechanism that matches the twisting mechanism. The conveying mechanism can transport the handle 101 and the connecting section, and the stop position corresponds to the axial direction of the clamping member 43. To be precise, the connecting section is fixedly connected to the conveying mechanism, and the handle 101 is connected to the conveying mechanism in a locking manner. When the conveying mechanism is paused, the connecting section, the handle 101, and the clamping member 43 are located in the same straight line direction (locking direction), and the handle 101 is connected to the conveying mechanism in a sliding manner along the locking direction. Specifically, the locking direction is parallel to the axial direction of the slide rail 11, and is also arranged to coincide with the axial direction of the clamping member 43, so that the conveying mechanism is adapted to the pushing mechanism, so that the pushing mechanism replaces manual assembly of the brush handle of the interdental brush, thereby improving the production efficiency of the brush handle.

[0027] For further reference, Figure 1The connecting member 42 includes a connecting block 421 and a connecting cylinder 422. One end of the connecting block 421 is connected to the output end of the twisting motor 41, the other end of the connecting block 421 is connected to one end of the connecting cylinder 422, and the other end of the connecting cylinder 422 is connected to the clamping member 43.

[0028] In this embodiment, the distance between the output end of the twisting motor 41 and the clamping member 43 is relatively large. In order to better and stably transmit the power of the twisting motor 41 to the clamping member 43, so that the clamping member 43 drives the handle 101 to rotate, the utility model uses the structural setting of the connecting block 421 and the connecting cylinder 422, combined with the output end of the twisting motor 41 passing through the connecting block 421 for rotation, and connected to the connecting cylinder 422, and the connecting block 421 is connected to the sliding member 30, so that the connecting block 421, the twisting motor 41 and the sliding member 30 form a whole in structure, thereby improving the stability of the power transmitted from the twisting motor 41 to the clamping member 43, and avoiding the large shaking amplitude of the handle 101 when the clamping member 43 rotates, and it cannot be assembled with the connecting section fixed on the conveying mechanism.

[0029] For further reference, Figure 1 and Figure 2 The clamping member 43 includes a first clamping jaw 431 and a second clamping jaw 432 . The first clamping jaw 431 and the second clamping jaw 432 are arranged opposite to each other, and a clamping position 433 adapted to the handle 101 is formed between the first clamping jaw 431 and the second clamping jaw 432 .

[0031] For further reference, Figure 1 and Figure 2 A concave surface 44 is provided on one side of the first clamping jaw 431 facing the second clamping jaw 432 and on one side of the second clamping jaw 432 facing the first clamping jaw 431 . The concave surface 44 is used to improve the clamping stability of the clamping position 433 on the handle 101 .

[0032] In this embodiment, since the cross-section of one end of the handle 101 connected to the clamping position 433 is elliptical, the utility model can increase the clamping position between the clamping jaws and the handle 101 by providing a concave surface 44 on both the first clamping jaw 431 and the second clamping jaw 432, thereby avoiding slipping between the clamping position 433 and the handle 101 when the clamping member 43 rotates.

[0033] For further reference, Figure 1 , Figure 2 and Figure 3 The clamping member 43 also includes two displacement blocks 45 for changing the size of the clamping position 433 . The other two opposite ends of the connecting cylinder 422 are provided with fixing grooves 423 adapted to the displacement blocks 45 , and the displacement blocks 45 are installed in the fixing grooves 423 .

[0034] In this embodiment, two fixing grooves 423 are provided at one end of the connecting cylinder 422 facing the clamping member 43, and the two fixing grooves 423 are arranged opposite to each other. Two displacement blocks 45 are respectively installed in the fixing grooves 423, and the displacement blocks 45 are fixed to the connecting cylinder 422 by screws. Through the structural setting of the fixing grooves 423, the adjustment direction of the clamping position 433 by the displacement block 45 can be limited, thereby avoiding the problem of looseness between the displacement block 45 and the connecting cylinder 422 during the rotation of the clamping member 43.

[0035] For further reference, Figure 1 , Figure 2 and Figure 3 The transposition block 45 is provided with a plurality of adjustment holes 451 , and the adjustment holes 451 are used to adjust the width between the first clamping jaw 431 and the second clamping jaw 432 .

[0036] In this embodiment, the transposition block 45 is provided with two adjustment holes 451 at one end of the clamping member 43, and the first clamping jaw 431 and the second clamping jaw 432 are both provided with connecting holes in the direction of the connecting cylinder 422. The clamping jaws of the utility model are threadedly connected to the adjusting holes 451 by screws passing through the connecting holes, so that the first clamping jaw 431 and the second clamping jaw 432 are relatively arranged in the two adjusting holes 451. At the same time, through the structural setting of the adjusting hole 451, the distance between the first clamping jaw 431 and the second clamping jaw 432 can be adjusted, thereby adjusting the size of the clamping position 433, so that the utility model can assemble brush handles of different specifications.

[0037] For further reference, Figure 1 The driving member 20 includes a driving unit 21 and a fixed vertical plate 22 . The fixed vertical plate 22 is connected to the fixed plate 10 , and the fixed vertical plate 22 abuts against the slide rail 11 . The driving unit 21 is connected to the fixed vertical plate 22 .

[0038] In this embodiment, the fixed vertical plate 22 is located at one end of the fixed plate 10, and the connecting block 421 is located at the other end of the fixed plate 10, and the connecting block 421 and the fixed vertical plate 22 are both connected and fixed to the fixed plate 10 by screws. At the same time, the fixed vertical plate 22 and the connecting block 421 are respectively abutted against the two ends of the slide rail 11, thereby limiting the moving range of the sliding member 30.

[0040] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
