[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] According to an embodiment of this utility model, a bristle supply mechanism and a brush making machine are provided. Please refer to [link / reference]. Figures 1 to 6 The component includes: a bristle support assembly 1, which has a support portion for supporting the bristles; the support portion extends along a first preset direction, and a preset angle is provided between the extension direction of the support portion and the ground, the preset angle being greater than or equal to 0° and less than 65°.

[0029] By adopting the above technical solution, the support part forms an inclination angle of 0° to 65° with the ground. When the bristles are placed on the support part, the specific inclination angle formed by the support part and the ground can effectively prevent the bristles from falling off the support part during installation. This effectively solves the technical problem that the container for holding the bristles is set vertically and the installation port is opened on one side of the container. This setting makes it easy for the bristles to fall off during placement, which not only causes waste but also results in low installation efficiency.

[0030] The preferred included angle is 0°.

[0031] Please refer to Figure 1 The bristle carrier assembly 1 includes: a carrier 2, which extends along a first preset direction, and has a carrier space 3 for accommodating bristles, and a bristle outlet communicating with the carrier space 3; the bristle outlet is located on one side of the carrier space 3 and is used to form a unidirectional conveying path in the carrier space 3; wherein, the carrier 2 forms a carrier section.

[0032] By adopting the above technical solution, the inclined structural feature 1 combined with the constraint of the bearing space 3 effectively reduces the falling of brush bristles during installation or conveying, reduces material loss compared to traditional vertical containers, and creates basic conditions for automated feeding.

[0033] Please refer to Figure 5 The support member 2 includes: a first connecting plate 4, a second connecting plate 5 and a third connecting plate 6 connected in sequence, with the first connecting plate 4 and the third connecting plate 6 arranged opposite to each other; the first connecting plate 4, the second connecting plate 5 and the third connecting plate 6 all extend along a first preset direction; wherein the first connecting plate 4, the second connecting plate 5 and the third connecting plate 6 form a support space 3.

[0034] By adopting the above technical solution, the U-shaped bearing space 3 formed by the first connecting plate 4, the second connecting plate 5 and the third connecting plate 6 achieves the directional guidance of the brush bristles through the three-sided enclosure structure; wherein the second connecting plate 5 serves as the bearing bottom surface to provide stable support.

[0035] Please refer to Figure 4The bristle supply mechanism further includes: a bristle feeding assembly 7, which includes: a first guide plate 8 extending along the extension direction of the carrier member 2, a first sliding groove 9 extending along the extension direction of the first guide plate 8; the first guide plate 8 is installed at the end of the first connecting plate 4 away from the second connecting plate 5; a second guide plate 10 extending along the extension direction of the carrier member 2, a second sliding groove 11 extending along the extension direction of the second guide plate 10; the second guide plate 10 is installed at the end of the third connecting plate 6 away from the second connecting plate 5; the first guide plate 8 and the second guide plate 10 are spaced apart; the first sliding groove 9 and the second sliding groove 11 are opposite to each other; and a bristle feeding plate 12 disposed between the first guide plate 8 and the second guide plate 10, with both ends of the bristle feeding plate 12 movably disposed within the first sliding groove 9 and the second sliding groove 11 along the extension direction of the second connecting plate 5, and the bristle feeding plate 12 is used to push the bristles in the carrier space 3 to a designated position.

[0036] By adopting the above technical solution, the symmetrical guiding structure of the first sliding groove 9 and the second sliding groove 11, combined with the double-sided sliding connection design of the bristle feeding plate 12, forms a high-precision linear pushing system; this structure enables the bristle feeding plate 12 to maintain a horizontal posture during long-stroke movement, avoids single-sided jamming, and ensures the uniform distribution of bristle pushing force.

[0037] Please refer to Figure 4 The wool feeding assembly 7 also includes: a first driving member 13, which is mounted on the second connecting plate 5 and extends and retracts along the extension direction of the second connecting plate 5; the extension end of the first driving member 13 is driven to connect with the wool feeding plate 12 so as to drive the wool feeding plate 12 to move through the extension end of the first driving member 13.

[0038] By adopting the above technical solution, the first driving component 13 is designed to be directly connected to the axial direction of the second connecting plate 5 and the bristle feeding plate 12, thereby achieving precise control of the pushing stroke and speed. This driving method forms a motion closed loop with the first sliding groove 9 and the second sliding groove 11, effectively compensating for changes in bristle accumulation resistance and improving the reliability of the pushing action.

[0039] Please refer to Figure 3 The bristle supply mechanism also includes a beating component 14, which is located above the bristle outlet. The beating component 14 has a beating part and a driving part. The beating part is movably disposed above the carrying space 3 in a vertical direction. The telescopic end of the driving part is driven to connect with the beating part so as to drive the beating part to move through the telescopic end of the driving part to beat the bristles in the carrying space 3.

[0040] By adopting the above technical solution, the vertical reciprocating motion of the tapping part driven by the drive part intermittently sorts and compacts the bristles in the bearing space 3; the timing of this action is coordinated with the bristle feeding component 7 to complete the material density adjustment before each push, ensuring the consistency of the bristle output per unit time.

[0041] Please refer to Figure 5 The tapping assembly 14 further includes: a tapping plate 15, which is movably disposed above the bearing space 3 in a vertical direction, and the tapping plate 15 forms a tapping part; a bracket 16, which is mounted on the bearing member 2; and a second driving member 17, which is mounted on the bracket 16, and the telescopic end of the second driving member 17 is drivenly connected to the tapping plate 15, and the second driving member 17 forms a driving part.

[0042] By adopting the above technical solution, the planar striking surface of the striking plate 15 and the rigid support structure of the bracket 16, together with the vertical driving path of the second driving component 17, form an efficient impact compaction mechanism; the matching design of the striking surface and the opening on the bearing space 3 enables the striking energy to be concentrated on the fluffy bristle layer, avoiding energy dispersion.

[0043] Please refer to Figure 6 The bristle supply mechanism also includes a bristle pushing assembly 18, which includes: a placement plate 19 extending along a second preset direction, the extension direction of the placement plate 19 being perpendicular to the extension direction of the carrier 2, the placement plate 19 being located on the side of the carrier 2 near the bristle outlet, the placement plate 19 being connected to the side of the first guide plate 8 away from the first drive member 13, a placement cavity 20 being formed on the placement plate 19, the placement cavity 20 being connected to the bristle outlet, and the placement cavity 20 being used to place the bristles pushed by the bristle feeding plate 12; and a sliding groove being formed on the placement plate 19; the sliding groove is positioned along the placement plate 19. The plate 19 extends in the extending direction, and the sliding groove communicates with the placement cavity 20; an output port is provided at the end of the sliding groove away from the placement cavity 20; a brush pushing plate 21 extends along the extending direction of the placement plate 19, and the brush pushing plate 21 is movably disposed on the side of the placement plate 19 away from the carrier 2 along the extending direction of the placement plate 19; a brush pushing groove 23 is provided on the brush pushing plate 21, and the brush pushing groove 23 extends along the height direction of the placement plate 19; the brush pushing groove 23 is used to push the bristles in the placement cavity 20 to move towards the output port along the extending direction of the sliding groove when the brush pushing plate 21 moves.

[0044] By adopting the above technical solution, the vertical extension feature of the pusher groove 23 and the horizontal channel of the placement cavity 20 form a spatial orthogonal layout; when the pusher plate 21 moves, the pusher groove 23 simultaneously generates a horizontal thrust on the bristles, so that the output bristle bundle meets the shape requirements of the implantation process.

[0045] Please refer to Figure 6The bristle supply mechanism also includes: a mounting frame 24, which is mounted on a mounting base, and a carrier 2 is mounted on the top of the mounting frame 24; the bristle pushing assembly 18 also includes: a third drive member 25, which is mounted on the mounting frame 24, and the third drive member 25 extends and retracts along the extension direction of the placement plate 19. The extension end of the third drive member 25 is driven to connect with the bristle pushing plate 21 so as to drive the bristle pushing plate 21 to move through the third drive member 25 so as to push the bristles in the placement cavity 20 to the designated position through the bristle pushing groove 23.

[0046] By adopting the above technical solution, the mounting bracket 24 serves as a unified installation benchmark. Through the integrated fixing of modules such as the bearing component 2 and the pusher assembly 18, the relative positional accuracy between the components is ensured. The linear drive connection between the third drive component 25 and the pusher plate 21 further optimizes the response speed and positioning accuracy of the pusher action.

[0048] Working principle:

[0049] Step 1: Load the brush bristles;

[0050] The bristles are placed in batches into the carrying space 3 of the bristle carrying component 1.

[0051] Step 2: Automatic tapping;

[0052] Start the tapping component 14, and the second drive component 17 drives the tapping plate 15 to move vertically and reciprocally, compacting the bristles in the bearing space 3 and eliminating loose gaps.

[0053] Step 3: Send the feathers to the push;

[0054] The first driving member 13 pushes the bristle feeding plate 12 to move linearly along the first sliding groove 9 and the second sliding groove 11, pushing the bristles from the bristle outlet into the placement cavity 20.

[0055] Step 4: Trimming and finishing;

[0056] The third driving component 25 drives the brush pusher plate 21 to slide along the placement plate 19, and the brush pusher groove 23 simultaneously applies a horizontal pushing force to the brush bristles, pushing the brush bristles to the implantation station of the brush making machine.

[0057] Step 5: Reset loop;

[0058] After a single feeding cycle is completed, the feeding plate 12 returns to its initial position, the patting plate 15 resets, and the pushing plate 21 retracts, preparing for the next work cycle.
