[0003] Especially in the hot melt bonding and fixed-length cutting links, the cutting mechanism of the existing brush piece processing device cannot synchronously achieve brush filament separation and precise positioning. During cutting, it is easy to cause molten adhesion due to the residual temperature, and manual intervention for separation is often required, and the burr rate of the cutting surface is relatively high. Summary of the Invention

[0016] 2. The present invention sets a brush cutting mechanism. Before cutting, the cold air nozzle will forcefully cool the hot melt bonding part, so that the PP brush wire can be quickly shaped and the surface viscosity can be reduced.

[0017] 3. The present invention sets a brush wire bonding mechanism, controls the reverse rotation of the upper and lower feeding components through the linkage of the gear drive, and cooperates with the elastic pressing roller structure of the clamping component to realize the automatic compression and precise alignment of the PP brush wire during the conveying process. It can integrate the brush wire arrangement, compression and conveying and hot melt shaping processes into the same workstation, which not only eliminates the problem of poor bonding caused by brush wire displacement in traditional processes, but also effectively improves processing efficiency.

[0018] 4. The present invention sets up an automatic feeding mechanism and utilizes the mutual cooperation between the material guiding inclined tube and the feeding funnel to enable the PP brush filaments to be discharged to the lower feeding assembly at a uniform rate.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1 In the prior art, the integration degree of the brush piece processing device is relatively low. The cutting mechanism cannot synchronously realize the separation and precise positioning of the brush wires, and it is easy to cause melting and adhesion due to the residual temperature during cutting, often requiring manual intervention for separation, and the burr rate of the cutting surface is relatively high. To solve this technical defect existing in the prior art, as Figure 1 、 Figure 2 and Figures 8 - 10 shown, this embodiment proposes a PP wire middle sweeping brush piece processing device with high integration degree, which completely solves the common melting and adhesion problems during the cutting process. A brush wire bonding mechanism 2 for conveying and heating PP brush wires is provided on the mounting plate 1 of the device. An automatic cloth feeding mechanism 3 is arranged on one side of the brush wire bonding mechanism 2. The automatic cloth feeding mechanism 3 is used for the PP brush wires to enter the pressing station of the brush wire bonding mechanism 2 at a constant rate and without accumulation. A brush piece cutting mechanism 4 is arranged on the other side of the brush wire bonding mechanism 2. A waste gas treatment mechanism 5 is movably installed on the mounting plate 1. After the staff puts the PP brush wires into the automatic cloth feeding mechanism 3, the automatic cloth feeding mechanism 3 can make the PP brush wires enter the inside of the brush wire bonding mechanism 2 neatly arranged. Subsequently, the brush wire bonding mechanism 2 will heat and bond one end of the PP brush wires. After the bonding is completed, the brush piece cutting mechanism 4 will perform fixed-length cutting on the PP brush wires, thus completing the processing of the brush pieces.

[0026] Specifically, the brush slice cutting mechanism 4 includes a cutting table 401 fixedly installed on the mounting plate 1. Two L-shaped sliding grooves 402 are symmetrically formed on the cutting table 401. A wire-pulling rubber block 404 is slidably connected inside the L-shaped sliding groove 402. An L-shaped tooth groove 405 is formed on the inner wall of the L-shaped sliding groove 402. A driving gear 406 is movably installed on the wire-pulling rubber block 404, and the driving gear 406 meshes with the L-shaped tooth groove 405. An installation vertical groove 403 is formed on the cutting table 401. A cutting tool 407 is movably installed inside the installation vertical groove 403. When the driving gear 406 rotates, the two wire-pulling rubber blocks 404 will first move downward simultaneously, and then move to both sides respectively. The gap between the two wire-pulling rubber blocks 404 is greater than the thickness of the cutting tool 407. During the synchronous downward movement of the two wire-pulling rubber blocks 404, the cutting tool 407 will not interfere with their movement. A driving cylinder 408 for driving the cutting tool 407 to move up and down is provided inside the installation vertical groove 403. When the cutting tool 407 moves downward rapidly, it will cut and process the bonded PP brush filaments. A cold air nozzle 409 is detachably installed on the mounting plate 1. The cold air nozzle 409 is connected to a cold air pipeline. After the cold air inside the cold air pipeline is ejected through the cold air nozzle 409, it will rapidly cool the hot-melt bonding part on the PP brush filaments, thereby preventing adhesion during the cutting process.

[0027] According to the above content, as Figure 2 shown, the PP brush filaments after hot-melt bonding treatment will pass in front of the cold air nozzle 409. At the same time, the cold air inside the cold air pipeline will be rapidly ejected through the cold air nozzle 409, thereby rapidly cooling the hot-melt part of the PP brush filaments and preventing adhesion during the subsequent cutting process.

[0028] Next, the cooled and formed PP brush filaments will move above the cutting table 401 and continue to move horizontally. At this time, the infrared sensor installed on the cutting table 401 will monitor the moving distance of the PP brush filaments.

[0029] When the moving distance reaches the specified length, the two wire-pulling rubber blocks 404 will first move downward under the action of the driving gear 406. At this time, the lower ends of the two wire-pulling rubber blocks 404 will be inserted into the interior of the PP brush filaments (at this time, the wire-pulling rubber blocks 404 have already contacted the cutting table 401). Subsequently, the two wire-pulling rubber blocks 404 will move to both sides respectively, thereby prying the PP brush filaments near the cutting site to both sides.

[0030] At the same time, the cutting tool 407 will rapidly move downward under the action of the driving cylinder 408, thereby cutting the bonded PP brush filaments into brush slices of equal length (as Figure 6 shown, Figure 6 the upper part is the appearance after cutting, and the lower part is formed by connecting the brush slices end to end and is used to manufacture the sweeping brush in the floor sweeper).

[0031] In this embodiment, by providing a brush slice cutting mechanism 4, through the meshing transmission between the L-shaped tooth groove 405 and the driving gear 406, the two wire-pulling rubber blocks 404 can first move downward and insert into the PP brush filaments, and then spread apart to both sides, so as to form a clear separation gap at the cutting site, effectively avoiding damage to the brush filaments by the cutting tool 407 during the cutting process. Moreover, in this embodiment, by providing the brush slice cutting mechanism 4, the cold air nozzle 409 will forcibly cool the hot melt bonding part before cutting, enabling the PP brush filaments to be quickly shaped and reducing the surface stickiness. Combining with the pre-separation effect of the wire-pulling rubber blocks 404, the common molten adhesion problem during the cutting process is completely solved.

[0032] Embodiment Two In order to integrate the processes of arranging, pressing and conveying the brush filaments and hot melt shaping at the same station, thereby improving the processing efficiency, on the basis of Embodiment One, as Figures 1 - 5 shown, this embodiment provides a brush filament bonding mechanism 2. Specifically, the brush filament bonding mechanism 2 includes a fixed platform 201. The fixed platform 201 is fixedly connected to the mounting plate 1. A lower feeding component 202 and an upper feeding component 203 are movably mounted on the mounting plate 1. A pressing component 204 is arranged above the upper feeding component 203. The pressing component 204 includes a mounting frame slidably connected to the mounting plate 1. A pressing roller is movably mounted on the mounting frame. When the mounting frame moves downward under the elastic force of the spring, the pressing roller will contact the upper feeding component 203, so that the upper feeding component 203 is in a taut state. A gear driving member 205 is provided on the back of the mounting plate 1. The gear driving member 205 can make the lower feeding component 202 and the upper feeding component 203 rotate in opposite directions. A telescopic bracket 206 is fixedly mounted on the mounting plate 1. An electric heater 207 is detachably mounted on the telescopic bracket 206. When the PP brush filaments move horizontally along the mounting plate 1, the electric heater 207 will automatically heat one end of the PP brush filaments to bond them together.

[0033] According to the above content, during the processing of the brush slice, the PP brush filaments will neatly fall onto the lower feeding component 202 under the action of the automatic feeding mechanism 3. Next, the PP brush filaments will enter the feeding gap between the lower feeding component 202 and the upper feeding component 203 and move synchronously with the lower feeding component 202 and the upper feeding component 203, so as to press and horizontally convey the PP brush filaments.

[0034] During the horizontal conveying process, one end of the PP brush filaments will pass through the inside of the electric heater 207. At the same time, the electric heater 207 will perform hot melt pressing treatment on the end of the PP brush filaments, so as to bond one end of the PP brush filaments together.

[0035] In this embodiment, by setting up the brush filament bonding mechanism 2, the upper feeding component 203 and the lower feeding component 202 are driven to rotate in opposite directions through the gear driving member 205, and then combined with the elastic pressing roller structure of the pressing component 204, automatic pressing and precise alignment of the PP brush filaments during the conveying process are achieved. The processes of arranging, pressing and conveying the brush filaments and hot melt shaping can be integrated at the same station, which not only eliminates the problem of poor bonding caused by the displacement of the brush filaments in the traditional process, but also effectively improves the processing efficiency.

[0036] Embodiment Three In order to ensure that the brush filaments can be neatly arranged and stably conveyed, and to minimize the displacement phenomenon in the hot melt bonding process, on the basis of the above embodiment, as Figures 1 - 7 and Figure 12 shown, this embodiment sets up an automatic feeding mechanism 3. Specifically, the automatic feeding mechanism 3 includes a feeding funnel 301 fixedly connected to the mounting plate 1. A guiding inclined pipe 302 is fixedly installed at the lower end of the feeding funnel 301. An installation square box 303 is arranged on the guiding inclined pipe 302. An inclined conveyor belt assembly 304 is movably installed inside the installation square box 303. After the PP brush filaments enter the inside of the guiding inclined pipe 302, they will be evenly discharged downward under the action of the inclined conveyor belt assembly 304, which can effectively prevent the PP brush filaments from accumulating on the lower feeding component 202. A leveling flat plate 305 is movably installed on the fixed platform 201. An electric telescopic rod 306 is arranged between the leveling flat plate 305 and the fixed platform 201. During the reciprocating contraction of the electric telescopic rod 306, the leveling flat plate 305 will reciprocate. During the reciprocating movement of the leveling flat plate 305, the uneven PP brush filaments can be aligned.

[0037] According to the above content, during feeding, the operator will put a bunch of PP brush filaments into the inside of the feeding funnel 301 at one time. As Figure 7 shown, next, the PP brush filaments inside the feeding funnel 301 will fall onto the lower feeding component 202 through the guiding inclined pipe 302.

[0038] During the movement of the PP brush filaments inside the guiding inclined pipe 302, the inclined conveyor belt assembly 304 will rotate at a constant speed. When the inclined conveyor belt assembly 304 rotates, it will have a certain limiting effect on the PP brush filaments, so as to ensure that the PP brush filaments can fall onto the lower feeding component 202 evenly at a constant speed, which can not only prevent the PP brush filaments from accumulating on the lower feeding component 202, but also prevent the PP brush filaments from shifting to a certain extent during the movement.

[0039] At the same time, the leveling flat plate 305 will reciprocate under the action of the electric telescopic rod 306. When the leveling flat plate 305 reciprocates, it will align one end of the PP brush filaments, which is convenient for the subsequent hot melt shaping processing.

[0040] In this embodiment, by setting up the automatic feeding mechanism 3 and utilizing the mutual cooperation between the material guiding inclined pipe 302 and the feeding funnel 301, the PP brush filaments can be discharged to the lower feeding component 202 at a uniform rate. Moreover, during the conveying process, the inclined conveyor belt component 304 exerts a limiting effect on the PP brush filaments, ensuring that the brush filaments can be neatly arranged and stably conveyed, effectively reducing the displacement phenomenon in subsequent processing. In addition, in this embodiment, by setting up the automatic feeding mechanism 3, the reciprocating motion of the alignment flat plate 305 is used to automatically align the PP brush filaments on the lower feeding component 202. This structure can quickly correct the unevenness at the ends of the brush filaments, ensure that the end faces of the brush filaments entering the hot melting station are neat, make the hot melting bonding position of the electric heater 207 more accurate, and avoid uneven bonding strength caused by the misalignment of the brush filaments.

[0041] Embodiment 4 In order to reduce the air pollution caused by the hot melting process in the production workshop and facilitate the cleaning and maintenance of the equipment, on the basis of the above embodiment, as Figure 1 、 Figure 4 and Figure 11 shown, this embodiment sets up an exhaust gas treatment mechanism 5. Specifically, the exhaust gas treatment mechanism 5 includes installation horizontal grooves 501 symmetrically opened on the installation plate 1. A sliding shield 502 is movably installed on the installation plate 1, and the sliding shield 502 is slidably connected to the installation horizontal grooves 501. A suction pump 503 is fixedly installed at the upper end of the sliding shield 502. An absorption round box 504 is provided at the output end of the suction pump 503. During the hot melting bonding process, the suction pump 503 will suck the exhaust gas generated in the hot melting area into the interior of the absorption round box 504. Activated carbon 505 is provided inside the absorption round box 504, and a number of exhaust round holes are opened on the surface of the absorption round box 504. After the exhaust gas enters the absorption round box 504, the activated carbon 505 will adsorb and remove the harmful substances in the exhaust gas.

[0042] According to the above content, during the hot melting bonding process of the brush piece, the sliding shield 502 will surround the outside of the hot melting area, and the exhaust gas generated during the hot melting bonding process will enter the interior of the absorption round box 504 under the action of the suction pump 503.

[0043] Next, the activated carbon 505 inside the absorption round box 504 will absorb and remove the harmful components in the exhaust gas. Subsequently, the gas will be discharged outward through the exhaust round holes, which can reduce the impact of the hot melting process on the surrounding environment to a certain extent.

[0044] Moreover, the sliding shield 502 can move horizontally along the installation horizontal grooves 501. When the staff needs to clean or maintain the hot melting area, they only need to push the sliding shield 502 to the side, without the need for frequent disassembly.

[0045] This embodiment sets up an exhaust gas treatment mechanism 5, and utilizes the synergistic effect of the sliding shield 502 and the suction air pump 503 to form a semi-closed exhaust gas collection space during the hot melting process, so that the exhaust gas is first adsorbed and purified by the absorption round box 504 before being discharged, which can effectively remove harmful substances such as benzene and aldehydes in the exhaust gas, and greatly reduce the air pollution in the production workshop; moreover, this embodiment sets up an exhaust gas treatment mechanism 5, and the sliding shield 502 is adjusted horizontally by installing a transverse groove 501, which can not only enclose the hot melting area during processing, but also be quickly pushed to one side during maintenance. This design breaks through the cumbersome problem of disassembly and assembly of traditional fixed covers, and significantly improves the efficiency of equipment cleaning, maintenance, replacement and other operations.

[0046] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by a person skilled in the art. The provision of power is also common knowledge in the art. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are not explained in detail in the present invention.

[0047] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
