Description

Technical Field

[0001] This utility model relates to the field of tufting machine technology, and in particular to a brush feeding mechanism for an automatic tufting machine. Background Technology

[0002] Brushes are common household items with a very high demand. The main component of a brush, the brush head, requires bristles to be implanted into the brush base during production.

[0003] A search revealed that application CN221153375U discloses a brush bristle feeding mechanism for an automatic brush bristle implantation machine. However, this feeding mechanism has the following drawbacks during use:

[0004] During the conveying process, the brushes on both sides can contact the conveyor belt, while the brushes in the middle cannot. This causes the brushes in the middle to accumulate, affecting the conveying effect.

[0005] Therefore, those skilled in the art provide a brush feeding mechanism for an automatic bristle implantation machine to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic bristle feeding mechanism for a bristle implantation machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An automatic bristle feeding mechanism for a bristle feeding machine includes a mounting frame and a pushing mechanism. Two adjusting plates are slidably provided on one side of the mounting frame, and two rotating rollers are rotatably provided through the adjusting plates. The two rotating rollers are connected to the same conveyor belt. A first motor is fixedly provided on one side of the adjusting plate, and the output end of the first motor is fixedly connected to the corresponding rotating roller for conveying the bristles downward.

[0009] An electric push rod is fixedly installed on one side of the mounting frame. The output end of the electric push rod is connected to two adjusting plates through a connector, which is used to drive the two conveyor belts to move closer to each other to convey the brush.

[0010] The pushing mechanism is located on one side of the mounting frame and between the two adjustment plates, and is used to push the brush.

[0011] As a further embodiment of this utility model, the connecting member includes a sliding rod slidably disposed on one side of the mounting bracket, and two sets of connecting rods are rotatably disposed on one side of the sliding rod, and the other end of the connecting rod is rotatably connected to the corresponding adjusting plate through a rotating shaft.

[0012] As a further embodiment of this utility model, the pushing mechanism includes a connecting frame fixedly mounted on one side of the mounting frame, two adjusting plates located between the mounting frame and the connecting frame, a screw rotatably mounted through one side of the connecting frame, a nut block threaded onto the screw, a push plate located on one side of the nut block, the push plate being located on the centerline in front of the two adjusting plates, and a driving component located at the top of the connecting frame for driving the screw to rotate and causing the push plate to move up and down.

[0013] As a further embodiment of this utility model, the driving component includes a second motor fixedly mounted on the top of the connecting frame, and the output end of the second motor is fixedly connected to the screw.

[0014] As a further embodiment of this utility model, two extension frames are provided on both sides of the connecting frame. The end of the extension frame away from the connecting frame is provided with a mounting ear. The mounting ear and one side of the mounting frame are provided with the same bolt, which is threadedly connected to the tufting machine.

[0015] As a further embodiment of this utility model, extension plates are slidably provided on both sides of the push plate, and elastic elements are provided inside the extension plates to drive the extension plates to contact one side of the conveyor belt.

[0016] As a further embodiment of this utility model, the elastic element includes two guide rods fixedly provided on the inner walls of both sides of the push plate, and a sliding groove corresponding to the guide rod is opened on one side of the extension plate. The guide rod is slidably disposed in the sliding groove, and a spring located inside the push plate is sleeved on the outer wall of the guide rod.

[0017] As a further embodiment of this invention, the nut block is slidably connected to one side of the connecting frame via a guide rail and a slider.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. By designing two sliding adjustment plates and a conveyor belt connected to them, the mechanism can flexibly adjust the conveying distance of the brushes, thereby achieving efficient and orderly feeding of the brushes. At the same time, the drive of the first motor ensures the stable operation of the conveyor belt, further improving the feeding efficiency.

[0020] 2. The combined design of the electric push rod and connector allows the two conveyor belts to move closer or further apart to accommodate the feeding needs of brushes of different specifications and quantities. This not only makes the process flexible and convenient but also greatly improves the adaptability and practicality of the equipment and increases the friction between the brushes and the conveyor belts.

[0021] 3. The design of the pushing mechanism, especially the combination of the screw, nut block and push plate, enables the brush to be pushed while being conveyed, improving the accuracy and efficiency of the operation. In addition, the push plate can always maintain contact with the conveyor belt during the pushing process, avoiding the brush in the middle from being pushed and accumulating.

Detailed Implementation

[0027] 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. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0028] Reference Figures 1-4An automatic bristle feeding mechanism for a bristle applicator includes a mounting frame 1 and a pushing mechanism. Two adjusting plates 2 are designed on one side of the mounting frame 1, and these two adjusting plates 2 can slide along the side of the mounting frame 1. Inside each adjusting plate 2, two rotating rollers 6 are rotatably mounted. The same conveyor belt 3 is driven and connected to these two rotating rollers 6, ensuring that the brush can move smoothly on the conveyor belt 3. To drive the conveyor belt 3, a first motor 4 is fixedly mounted on one side of the adjusting plate 2, and the output end of the first motor 4 is fixedly connected to the corresponding rotating roller 6, thereby realizing the downward conveying function of the brush.

[0029] To adjust the spacing between the two conveyor belts 3, an electric push rod 11 is fixedly installed on one side of the mounting frame 1. The output end of the electric push rod 11 is connected to two adjusting plates 2 via a connector. The connector includes a sliding rod 12 slidably mounted on one side of the mounting frame 1, with two sets of connecting rods 13 rotatably mounted on one side of the sliding rod 12. The other end of the connecting rods 13 is rotatably connected to the corresponding adjusting plate 2 via a rotating shaft 14. When the electric push rod 11 extends or retracts, it pushes or pulls the adjusting plate 2 through the rotation of the connecting rods 13 and the rotating shaft 14, thereby adjusting the spacing between the two conveyor belts 3.

[0030] Next, the pushing mechanism is set on one side of the mounting frame 1, between the two adjusting plates 2. It mainly includes a connecting frame 5 fixedly mounted on one side of the mounting frame 1. A screw 7 is rotatably mounted through one side of the connecting frame 5, with a nut block 8 threaded onto the screw 7. A push plate 10 is connected to one side of the nut block 8, and the push plate 10 is located on the center line between the two adjusting plates 2. To drive the screw 7 to rotate, a driving component, specifically a second motor 9, is set on the top of the connecting frame 5, with its output end fixedly connected to the screw 7. When the second motor 9 rotates, it drives the screw 7 to rotate, which in turn drives the nut block 8 and the push plate 10 to move up and down through the threaded engagement, thus pushing the brush.

[0031] To ensure the pushing mechanism can be stably installed on the hair implantation machine, two extension frames 17 are provided on both sides of the connecting frame 5. The end of the extension frame 17 away from the connecting frame 5 is provided with a mounting ear 18. The pushing mechanism can be firmly connected to the hair implantation machine by the same bolt 15 that runs through the mounting ear 18 and one side of the mounting frame 1.

[0032] Furthermore, to increase the contact and stability between the push plate 10 and the conveyor belt 3, extension plates 16 are slidably arranged on both sides of the push plate 10. Each extension plate 16 contains an elastic element for driving it to contact one side of the conveyor belt 3. This elastic element specifically includes two guide rods 21 fixedly mounted on the inner walls of both sides of the push plate 10, and a sliding groove 20 corresponding to the guide rods 21 opened on one side of the extension plate 16, with the guide rods 21 slidably positioned within the sliding groove 20. A spring 22 is also fitted inside the push plate 10 on the outer wall of the guide rods 21, with both ends of the spring 22 fixedly connected to the adjacent sides of the push plate 10 and the extension plate 16, respectively. Thus, when the push plate 10 moves up and down, the extension plate 16 will always maintain contact with the conveyor belt 3 under the action of the spring 22.

[0033] Finally, to ensure that the nut block 8 can slide stably on one side of the connecting frame 5, a sliding connection between the guide rail and the slider is adopted. In this way, when the screw 7 rotates, the nut block 8 can slide stably along the guide rail, thereby driving the push plate 10 to move up and down.

[0034] Working principle: In use, the brush is installed on the automatic tufting machine using multiple bolts 15. Then, the brush is placed between two conveyor belts 3. The electric push rod 11 is then activated to extend. During the extension of the electric push rod 11, the sliding rod 12 moves upward. The upward movement of the sliding rod 12 causes two adjusting plates 2 to move closer together via two sets of connecting rods 13, thereby causing the two conveyor belts 3 to move closer together to clamp the brush. Then, the first motor 4 is activated to drive the rotating roller 6 to rotate. During the rotation of the rotating roller 6, the conveyor belt 3 moves and conveys the brush. At the same time, the second motor 9 is activated to drive the screw 7 to rotate. During the rotation of the screw 7, the nut block 8 moves up and down. The up and down movement of the nut block 8 causes the push plate 10 to move up and down. During the downward movement of the push plate 10, the brush between the two conveyor belts 3 is pushed downward. When the extension plate 16 contacts the conveyor belt 3, it moves inward according to the distance of the conveyor belt 3 and compresses the spring 22, so that the outer side of the extension plate 16 is always in contact with one side of the conveyor belt 3, thus pushing the brush to move.

[0035] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
