Description

Technical Field

[0001] The utility model relates to the field of writing brush processing equipment, in particular to a multi-station combing device for writing brush processing. Background Art

[0002] After the preparation of the brush is completed, in order to make it smoother when writing, it is usually necessary to comb the bristles of the brush. In the past, combing was done manually, and the processing efficiency was relatively low. Later, with the advancement of science and technology, people developed relevant automated equipment to comb the bristles of the brush, thus forming an assembly line for brush processing, which effectively improved production efficiency. For example, a Chinese patent disclosed patent number CN211075288U, entitled a multi-station combing device for brush processing, which installs the combing bristles on a belt when combing the bristles of the brush, and combs the bristles by the rotation of the belt. However, in this way, the combing bristles only act on the surface of the brush bristles during the process of following the rotation of the belt, and the middle area of the brush bristles cannot be combed, which results in the brush bristles of the brush not being thoroughly combed. Based on this, the present utility model is proposed. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0021] See also Figures 1-6This embodiment provides a multi-station combing device for brush processing. The device includes a brush holder 3 for securing the brushes. Multiple processing stations are distributed on the brush holder 3. The brush holder 3 utilizes currently known prior art technology. The specific structure can be referenced in the structure disclosed in Patent No. CN211075288U. Each processing station can accommodate a brush and can rotate along its own axis to achieve a comprehensive combing operation. A combing brush 6 is disposed below each processing station. A rotating plate 4 is disposed between each adjacent combing brush 6. Rotating plates 4 are also disposed at the ends of the two outermost combing brushes 6. All rotating plates 4 are capable of synchronous axial rotation. Each rotating plate 4 has a second limiting groove 21 defined within it. One end of the second limiting groove 21 is located at the center of the rotating plate 4, while the other end extends radially outward from the rotating plate 4. A sliding post 18 is fixedly connected to each end of each combing brush 6. The sliding post 18 extends into the corresponding second limiting groove 21 and slidably engages with it. When the combing brush 6 combs the brush hairs, all the second limiting grooves 21 on the rotating plate 4 are distributed in the vertical direction, and the sliding column 18 slides inside the second limiting groove 21 toward the center of the rotating plate 4. At this time, the combing brush 6 moves from top to bottom to comb the brush hairs. When the combing brush 6 moves below the brush hairs, it has to move again above the brush hairs to comb them again until the brush completes a 360° rotation inside the brush fixing tooling 3. However, during the upward movement of the combing brush 6, it is required not to move in the vertical direction, otherwise the combed brush hairs will be disrupted. Therefore, the combing brush 6 needs to be moved upward. During the return process, the combing brush 6 is misaligned and avoided with the brush hair. To this end, all the rotating plates 4 are first rotated a certain angle in the direction away from the brush fixing tooling 3, so that the second limit groove 21 is in an inclined state. In this state, the entire combing brush 6 can avoid the brush hair. After the slide column 18 slides to a suitable distance in the second limit groove 21 (the slide column 18 does not slide to the end of the second limit groove 21), all the rotating plates 4 are rotated in the opposite direction again to make the second limit groove 21 in a vertical state. At this time, the combing brush 6 can be inserted into the upper end of the brush hair, and the combing brush 6 can move downward to comb the brush hair.

[0022] Specifically, in this embodiment, two support frames 2 are fixed on the top of the workbench 1, and a rotating plate 4 is installed on one side of the two support frames 2 to rotate toward each other. A support plate 7 is provided under all the remaining rotating plates 4. The bottom end of the support plate 7 is fixed on the workbench 1, and the top is fixedly connected to a holding plate 20. The rotating plates 4 are rotatably embedded in the corresponding holding plates 20. The holding plates 20 can support several rotating plates 4 in the middle. All the rotating plates 4 are connected and fixed by the second linkage column 22. This can ensure that all the rotating plates 4 rotate synchronously. Of course, the rotation of the rotating plates 4 is driven by the first motor 5 installed on the outside of one of the support frames 2. In addition, in this embodiment, there are certain requirements for the distribution position of the second linkage column 22. The second linkage column 22 is installed on Figure 1 In the position shown, when the first motor 5 drives all the rotating plates 4 to rotate clockwise until the second linkage column 22 contacts the holding plate 20 and then stops rotating, that is, the second linkage column 22 can also limit the rotation angle of the rotating plates 4, so that all the rotating plates 4 can only rotate clockwise to a fixed angle (in actual conditions, rotating the rotating plates 4 by 8° can ensure that the combing brush 6 can smoothly avoid the misalignment with the brush hairs).

[0023] The top of the lifting rod 15 is hinged with a connecting rod 17, and the end of the connecting rod 17 is connected to the corresponding combing brush 6. The lifting rod 15 is synchronously lifted and lowered inside the corresponding fixed frame 10, which can drive the combing brush 6 to move periodically to comb the brush hair. When the second limiting groove 21 is in the vertical direction, the lifting rod 15 slides downward inside the fixed frame 10. At this time, the combing brush 6 moves downward in the vertical direction to comb the brush hair. When the second limiting groove 21 is in an inclined state, the lifting rod 15 slides upward inside the fixed frame 10. At this time, the connecting rod 17 rotates relative to the lifting rod 15, and the connecting rod 17 acts on the combing brush 6, causing the sliding posts 18 on both sides of the combing brush 6 to slide inside the second limiting groove 21, thereby causing the combing brush 6 to move upward in the inclined direction.

[0024] Furthermore, in this embodiment, the bottoms of all the lifting rods 15 are fixedly connected by the first linkage column 16, and all the first limiting grooves 19 corresponding to the sliding tracks of the first linkage column 16 on both sides of the fixed frame 10 are provided. The two ends of the first linkage column 16 are integrally formed with sliding rollers 14, and slide rails 8 are respectively mounted on both sides of the upper end of the workbench 1. The interiors of the two slide rails 8 are both slidingly guided and installed with sliding plates 9. The two sliding plates 9 are respectively provided with guide grooves 13 that pass through the plate surfaces. The sliding rollers 14 extend into the corresponding guide grooves 13 and are slidably connected thereto. The two sliding plates 9 slide inside the slide rails 8 to drive the lifting rods 15 to move in the vertical direction relative to the fixed frame 10. It should be further explained that when the second limit groove 21 is in an inclined state, after the first linkage column 16 slides upward to the top of the first limit groove 19, the slide columns 18 on both sides of the combing brush 6 still have a certain distance D from the end of the second limit groove 21. Because when the rotating plate 4 rotates to the second limit groove 21 and is distributed in a vertical direction, the combing brush 6 moves toward the direction of the brush hair, and the slide column 18 will also slide relative to the second limit groove 21. Therefore, the above-mentioned distance D is to reserve sliding space for the slide column 18 relative to the second limit groove 21. When the second limit groove 21 rotates to a vertical state, the slide column 18 can just slide to the end of the second limit groove 21.

[0025] The two sliding plates 9 can be driven by the synchronous movement of two sliding plates 9 of the same specifications to drive the lifting rod 15 to rise and fall relative to the fixed frame 10. Of course, another more reasonable method can also be adopted. Specifically, the bottom of the two sliding plates 9 passes through the workbench 1 downward and is fixedly connected to a rack 12, and the bottom of the workbench 1 is located between the two racks 12 and a gear disk 11 is rotatably installed (the gear disk 11 is connected to the second motor drive installed at the bottom of the workbench 1). The two racks 12 are respectively engaged with the gear disk 11, and the guide grooves 13 on the two sliding plates 9 are tilted in opposite directions. When the second motor drives the gear disk 11 to rotate, the two sliding plates 9 move in opposite directions through the engagement of the rack 12 and the gear disk 11. Since the guide grooves 13 on the two sliding plates 9 are tilted in opposite directions, it is equivalent to applying force to both sides of the first linkage column 16 to make it move in the vertical direction.

[0026] As a preferred embodiment, this embodiment also has protrusions extending outward from the positions where the two sliding plates 9 contact the sliding rails 8, and the inner side of the sliding rails 8 is recessed inward along its length to form a groove that matches it. The cooperation between the protrusions and the grooves can improve the sliding stability of the sliding plates 9 and prevent them from slipping off the sliding rails 8.
