Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brush production, in particular to an auxiliary feeding device for producing brush filaments. Background Art
[0002] The production of brush filaments is a delicate and multi-step process, which involves key steps such as material selection, processing and forming, heat treatment and final cutting. In the production line of brush filaments, every link is crucial and directly affects the quality, durability and performance of the final product.
[0003] The final stage of brush production is the cutting stage. At present, many factories still use manual intermittent pushing to cut brush wires. Although this method is simple, it has many shortcomings. First, manual pushing cannot ensure the speed and stability of the brush wire entering the wire cutter, which may lead to inconsistent cutting lengths and affect the specifications of the brush wire. Secondly, manual operation is prone to fatigue, which reduces work efficiency and also increases safety hazards. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an auxiliary feeding device for producing bristle brush filaments with consistent cutting length of the filaments.
[0005] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: an auxiliary feeding device for the production of bristle brushes and brush filaments, including a cutting machine and a conveying frame, the cutting machine is equipped with a mounting plate and a cutting knife, the conveying frame is connected to one side of the cutting machine, and also includes a rotating seat, a pressure roller, a gear and a rack, the rotating seat is fixedly connected to the side of the mounting plate, a pressure roller is rotatably connected between the rotating seats, a coaxial gear is fixedly connected to the middle of the pressure roller, the rack is fixedly connected to the side of the cutting knife, and the rack can contact and mesh with the gear.
[0006] A further preferred solution of the utility model is that the gear is a one-way gear.
[0007] A further preferred solution of the utility model is: it also includes a fixed plate, a guide rod, a push plate and a reset spring, the conveying frame is fixedly connected to the guide rod, the push plate is slidably connected to the guide rod, and a reset spring is connected between the push plate and the fixed plate.
[0008] A further preferred solution of the utility model is that it also includes a handle, and the handle is fixedly connected to the side of the push plate.
[0009] A further preferred solution of the utility model is that it also includes an anti-skid pad, and the handle is covered with the anti-skid pad.
[0010] A further preferred solution of the utility model is: it also includes balls, and the balls are evenly arranged on the upper surface of the conveying frame.
[0011] A further preferred solution of the utility model is: it also includes a clamping rod, which is fixed to the fixing plate, and the clamping rod can limit and fix the push plate by clamping.
[0012] A further preferred solution of the utility model is: it also includes a foam pad, and the outer part of the pressure roller is covered with the foam pad.
[0013] Compared with the prior art, the advantage of the utility model is that a gear is set to limit the pressure roller to rotate in one direction. When the cutter moves downward, the brush filaments are cut into segments, and then the cutter moves upward. During this period, the rack will drive the gear to rotate, and then drive the pressure roller to rotate. The pressure roller guides the brush filaments to the right. Since the reciprocating distance of the cutter is a fixed value, the distance that the pressure roller drives the brush filaments to move is also a fixed value. Therefore, the cutter can cut the brush filaments into uniform length specifications, thereby improving the quality of the brush. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0021] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.
[0022] This embodiment mainly describes the structure of the feeding device, which is as follows:
[0023] An auxiliary feeding device for producing bristle brush filaments, such as Figure 1-Figure 3 As shown, it includes a cutting machine 1 and a conveying frame 4, the cutting machine 1 is equipped with a mounting plate 2 and a cutting knife 3, the conveying frame 4 is connected to the left side of the cutting machine 1, and also includes a rotating seat 5, a pressure roller 6, a gear 7 and a rack 8. The rotating seat 5 is fixedly connected to the side of the mounting plate 2, and the pressure roller 6 is rotatably connected between the rotating seats 5. The outer surface of the pressure roller 6 is provided with a foam pad 17, and a coaxial gear 7 is fixedly connected to the middle of the pressure roller 6. The gear 7 is a one-way gear, and the rack 8 is fixedly connected to the side of the cutting knife 3. The rack 8 can contact and mesh with the gear 7. The gear 7 limits the pressure roller 6 to rotate in one direction. Therefore, when the cutting knife 3 moves downward, it cannot drive the pressure roller 6 to rotate. At this time, the cutting knife 3 cuts the brush wire into segments, and then the cutting knife 3 moves upward. During this period, the rack 8 will drive the gear 7 to rotate, and then drive the pressure roller 6 to rotate, and the pressure roller 6 guides the brush wire to the right.
[0024] like Figure 2 As shown, it also includes a fixed plate 9, a guide rod 10, a push plate 11 and a return spring 13. The guide rod 10 is fixedly connected to the conveying frame 4, the push plate 11 is slidably connected to the guide rod 10, and a return spring 13 is connected between the push plate 11 and the fixed plate 9.
[0025] like Figure 1 and Figure 3 As shown, a handle 12 is also included. The handle 12 is fixedly connected to the side of the push plate 11. An anti-skid pad 14 is provided on the handle 12 to facilitate the staff to operate the handle 12.
[0026] like Figure 1 and Figure 4 As shown, it also includes balls 15. The balls 15 are evenly arranged on the upper surface of the conveying frame 4. When the brush wire is placed on the conveying frame 4, the balls 15 effectively reduce the friction coefficient between the brush wire and the conveying frame 4, thereby improving the passing rate of the brush wire.
[0027] like Figure 1 As shown, a clamping rod 16 is also included. The clamping rod 16 is fixed to the fixing plate 9. The clamping rod 16 can limit and fix the push plate 11 by clamping.
[0028] Working principle: Move the push plate 11 to the left through the handle 12 until the card rod 16 limits and fixes the push plate 11, and then place the brush wire in the conveying frame 4, and then rotate the end of the card rod 16 to release the fixation of the push plate 11, the left end of the brush wire will be pushed by the push plate 11, and the right end of the brush wire is located at the cutter 3, turn on the cutting machine 1 to drive the cutter 3 to reciprocate up and down. Because the gear 7 limits the pressure roller 6 to rotate in one direction, when the cutter 3 moves downward, it cannot drive the pressure roller 6 to rotate. At this time, the cutter 3 cuts the brush wire, and then the cutter 3 moves upward. During this period, the rack 8 will drive the gear 7 to rotate, and then drive the pressure roller 6 to rotate. The pressure roller 6 guides the brush wire to the right. When the cutter 3 moves downward again, the above action will be repeated. Since the reciprocating distance of the cutter 3 is a fixed value, the pressure roller 6 drives the brush wire to move a fixed value. Therefore, the cutter 3 can cut the brush wire into uniform length specifications, thereby improving the quality of the brush.
