Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric carding technology, and more particularly to a nonwoven fabric carding machine. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It is called cloth because it resembles fabric in appearance and possesses some of its properties. Currently, the processing of non-woven fabric requires carding the fiber raw materials. The purpose of this is to comb the fiber bundles into individual fibers and ensure the uniformity of the web, which involves the use of carding machines. During the processing of non-woven fabric, a large amount of lint is generated. If this lint is not collected and absorbed in time, it will diffuse into the air, and inhaling large quantities can easily cause harm to the body.

[0003] A search revealed Chinese patent publication number CN214004885U, which discloses an automatic carding machine for nonwoven fabrics. The machine includes a main body with a conveyor belt installed at its feed inlet. A dust cover with an opening at the bottom is located directly above the conveyor belt, and the dust cover has an inlet on its side near the feed inlet. It also includes a dust collection assembly. One end of a dust collection pipe is connected to the dust cover, and the other end is connected to the air inlet of a fan. One end of a dust exhaust pipe is connected to the air outlet of the fan, and the other end is connected to the top of a dust collection box. The bottom of the dust cover has an insertion block, and the conveyor belt has an insertion groove for inserting the insertion block. The conveyor belt also has a limiting component for stabilizing the insertion block in the insertion groove. This device effectively reduces the amount of fine fiber raw materials floating in the air during processing, protecting the health of the operator.

[0004] However, when using the above-mentioned device, the negative pressure generated by the adsorption mechanism will attract materials on the normal production path, causing unnecessary waste. Furthermore, after a period of production, when cleaning the fine fiber raw materials on the dust cover and in the dust collection box, it is necessary to stop the adsorption of the fine fiber raw materials by the device, which leads to a reduction in the production efficiency of the device. Summary of the Invention

[0005] The purpose of this invention is to provide a nonwoven fabric carding machine that reduces the impact of negative pressure on normal production, greatly improves the continuity of adsorption, and also improves the continuity of the cleaning process, thereby improving the overall work efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a nonwoven fabric carding machine, comprising: a carding machine body, an outer cover provided outside the carding machine body, a negative pressure suction device provided on the side of the outer cover opposite to the felt board, the suction head of the negative pressure suction device being able to extend into the interior of the outer cover, and a side support provided between the carding machine body and the suction head, two side supports located on the same side being arranged opposite to each other, and a plurality of felt boards arranged vertically between the two side supports, a shaft being fixedly connected to the inner side of the felt board, the shaft being rotatably connected to the side support, and a synchronous pulley being fixedly installed at one end of the shaft, and the plurality of synchronous pulleys being connected by a synchronous belt drive;

[0007] Two slide rails are vertically spaced between the felt board and the suction head. A sliding chamber is slidably connected between the two symmetrically arranged slide rails. Several turntables are spaced apart on one side of the sliding chamber relative to the felt board. Several rubber rods are fixedly installed on the surface of the turntables.

[0008] The following are further improvements to the above technical solution:

[0009] 1. In the above scheme, a collection box is provided inside the negative pressure aspirator, and a support shell with a built-in roller is fixedly installed on the outer wall of the negative pressure aspirator, and a membrane roll is wound on the circumferential outer wall of the roller.

[0010] 2. In the above scheme, the end of the membrane roll is fixedly connected with several hooks, and a snap-fit ​​bracket that cooperates with the hooks is provided on the outer wall of the collection box.

[0011] 3. In the above scheme, a torsion spring return device connected to the roller is provided on one side of the support housing.

[0012] 4. In the above scheme, a multi-port pipe is provided inside the sliding chamber, and the air outlet of the multi-port pipe is located between two adjacent turntables. The air inlet of the multi-port pipe is connected to the air outlet of a fan.

[0013] 5. In the above scheme, a second synchronous wheel is fixedly connected inside the sliding chamber and to the turntable, and a second synchronous belt is connected to the outer wall of the second synchronous wheel.

[0014] 6. In the above scheme, one of the second synchronous pulleys is fixedly connected to the output shaft of a stepper motor, and the stepper motor is fixedly installed on the outer wall of the sliding chamber.

[0015] 7. In the above scheme, the fan is installed on the side of the sliding chamber opposite to the felt plate.

[0016] 8. In the above scheme, one of the support shafts is fixedly connected to the output shaft of the servo motor, and the servo motor is fixedly mounted on the side bracket.

[0017] 9. In the above scheme, the support shaft is rotatably connected to the side bracket via a damping bearing.

[0018] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0019] 1. The nonwoven fabric carding machine of the present invention has a negative pressure suction device on one side of the outer cover opposite to the felt board. The suction head of the negative pressure suction device can extend into the inside of the outer cover. Several felt boards are arranged vertically between the two side supports.

[0028] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0029] Example 1: A nonwoven fabric carding machine, comprising: a carding machine body 1, characterized in that: an outer cover 3 is provided outside the carding machine body 1, and a negative pressure suction device 402 is provided on the side of the outer cover 3 opposite to the felt plate 205 respectively;

[0030] The front end of the carding machine body is covered by an outer cover, which seals the lint inside the cover. Multiple felt plates set on both sides of the carding machine body adsorb the floating lint.

[0031] The suction head 401 of the negative pressure suction device 402 can extend into the outer cover 3. A side support 201 is provided between the combing machine body 1 and the suction head 401. Two side supports 201 located on the same side are arranged opposite each other. Several felt plates 205 are arranged vertically between the two side supports 201. A shaft 204 is fixedly connected to one side of the inner side of the felt plate 205. The shaft 204 is rotatably connected to the side support 201. A synchronous pulley 202 is fixedly installed at one end of the shaft 204. Several synchronous pulleys 202 are connected by a synchronous belt 203.

[0032] After a certain period of adsorption, the servo motor controls one of the support shafts to rotate. Under the action of the synchronous pulley and synchronous belt, multiple lint grids are flipped over, with the side containing lint turning inward. This creates a partition through the lint grids, preventing negative pressure adsorption from affecting normal production. At the same time, it achieves automatic adsorption and collection of lint, reducing cleaning difficulty. In addition, through double-sided adsorption, uninterrupted adsorption can be achieved. With this structure, automatic collection of lint is achieved without affecting normal production, reducing the workload of workers and facilitating the secondary use of lint, thus reducing production costs.

[0033] Two slide rails 501 are vertically spaced between the felt plate 205 and the suction head 401. A sliding chamber 502 is slidably connected between the two symmetrically arranged slide rails 501. Several turntables 507 are spaced apart on one side of the sliding chamber 502 relative to the felt plate 205. Several rubber rods 506 are fixedly installed on the surface of the turntables 507.

[0034] During negative pressure collection, the stepper motor drives the turntable to rotate rapidly, causing multiple rubber rods to rotate and act on the inner wall of the felt board, separating the lint on the felt board. Under the action of the fan, air is continuously delivered, blowing up the lint and guiding it through the sliding chamber to act sequentially on multiple felt boards, which helps to prevent the lint from adhering too tightly and ensures thorough collection.

[0035] The negative pressure suction device 402 has a collection box 403 inside, and a support housing 404 with a built-in roller 408 is fixedly installed on the outer wall of the negative pressure suction device 402. A membrane roll 406 is wound around the circumferential outer wall of the roller 408.

[0036] The end of the aforementioned membrane roll 406 is fixedly connected with several hooks 407, and a snap-fit ​​bracket 410 that cooperates with the hooks 407 is provided on the outer wall of the aforementioned collection box 403.

[0037] A torsion spring return device 405 connected to a roller 408 is provided on one side of the aforementioned support housing 404.

[0038] A multi-port pipe 505 is provided inside the sliding chamber 502, and the air outlet 510 of the multi-port pipe 505 is located between two adjacent turntables 507. The air inlet of the multi-port pipe 505 is connected to the air outlet of a fan 503. Furthermore, the air outlet of the multi-port pipe continuously blows the lint, effectively reducing the difficulty of cleaning caused by the lint adhering too tightly, and improving the cleaning effect.

[0039] Inside the sliding chamber 502 and fixedly connected to the turntable 507, there is a second synchronous pulley 508, and the outer wall of the second synchronous pulley 508 is connected to a second synchronous belt 509.

[0040] One of the aforementioned second synchronous pulleys 508 is fixedly connected to the output shaft of a stepper motor 504, which is fixedly mounted on the outer wall of the sliding chamber 502.

[0041] One of the aforementioned support shafts 204 is fixedly connected to the output shaft of the servo motor 207, and the servo motor 207 is fixedly mounted on the aforementioned side bracket 201.

[0042] The aforementioned support shaft 204 is rotatably connected to the side bracket 201 via a damping bearing 206.

[0043] The aforementioned rubber rods 506 are distributed at equal intervals.

[0044] The aforementioned turntables 507 are equidistantly spaced along the length of the sliding chamber 502.

[0045] Example 2: A nonwoven fabric carding machine, comprising: a carding machine body 1, characterized in that: an outer cover 3 is provided outside the carding machine body 1, and a negative pressure suction device 402 is respectively provided on the side of the outer cover 3 opposite to the felt plate 205. The suction head 401 of the negative pressure suction device 402 can extend into the outer cover 3. A side support 201 is provided between the carding machine body 1 and the suction head 401. Two side supports 201 on the same side are arranged opposite to each other, and a plurality of felt plates 205 are arranged vertically between the two side supports 201. A shaft 204 is fixedly connected to one side of the inner side of the felt plate 205. The shaft 204 is rotatably connected to the side support 201, and a synchronous pulley 202 is fixedly installed at one end of the shaft 204. The plurality of synchronous pulleys 202 are connected by a synchronous belt 203.

[0046] The suction head of the negative pressure suction device attracts the flying lint, and the felt plate located between the suction head and the carding machine body automatically adsorbs the lint. The felt plate also forms a barrier against the negative pressure, greatly reducing the impact of the negative pressure on normal production. In addition, the felt plate can be flipped to achieve double-sided adsorption.

[0047] Two slide rails 501 are vertically spaced between the felt plate 205 and the suction head 401. A sliding chamber 502 is slidably connected between the two symmetrically arranged slide rails 501. Several turntables 507 are spaced apart on one side of the sliding chamber 502 relative to the felt plate 205. Several rubber rods 506 are fixedly installed on the surface of the turntables 507.

[0048] While adsorbing on one side, the rotating disc can drive the rubber rod to clean the other side, greatly improving the continuity of adsorption and cleaning, thereby increasing overall work efficiency.

[0049] The negative pressure suction device 402 has a collection box 403 inside, and a support housing 404 with a built-in roller 408 is fixedly installed on the outer wall of the negative pressure suction device 402. A membrane roll 406 is wound around the circumferential outer wall of the roller 408.

[0050] The end of the membrane roll 406 is fixedly connected with several hooks 407, and a snap-fit ​​bracket 410 that cooperates with the hooks 407 is provided on the outer wall of the collection box 403.

[0051] During operation, lint enters the collection box inside the negative pressure suction device through the suction head. When the collection box is removed, some lint may fly up due to the removal action, making collection difficult. By incorporating a membrane roll, which is hooked onto the clip frame before removal, the membrane roll unfolds simultaneously when the collection box is removed, covering the collection box with film. After complete extraction to ensure no lint flies up, the hook is removed, and the lint is then collected. This structure ensures the stability of lint collection and further reduces the difficulty of operation.

[0052] A torsion spring return device 405 connected to a roller 408 is provided on one side of the aforementioned support housing 404.

[0053] A multi-port pipe 505 is provided inside the sliding chamber 502, and the air outlet 510 of the multi-port pipe 505 is located between two adjacent turntables 507. The air inlet of the multi-port pipe 505 is connected to the air outlet of a fan 503.

[0054] Inside the sliding chamber 502 and fixedly connected to the turntable 507, there is a second synchronous pulley 508, and the outer wall of the second synchronous pulley 508 is connected to a second synchronous belt 509.

[0055] One of the aforementioned second synchronous pulleys 508 is fixedly connected to the output shaft of a stepper motor 504, which is fixedly mounted on the outer wall of the sliding chamber 502.

[0056] The aforementioned fan 503 is installed on the side of the aforementioned sliding chamber 502 opposite to the felt plate 205.

[0057] One of the aforementioned support shafts 204 is fixedly connected to the output shaft of the servo motor 207, and the servo motor 207 is fixedly mounted on the aforementioned side bracket 201.

[0058] The aforementioned support shaft 204 is rotatably connected to the side bracket 201 via a damping bearing 206.

[0059] A handle 409 is provided on the outer wall of the collection box 403, and the handle 409 and the card holder 410 are located on the same side of the outer wall.

[0060] The aforementioned card holder 410 has an L-shaped structure.

[0061] The working principle is as follows:

[0062] During production, the front end of the carding machine body is covered by an outer cover to seal the lint inside the cover. Multiple felt plates set on both sides of the carding machine body adsorb the floating lint.

[0063] After a certain period of adsorption, the servo motor controls one of the support shafts to rotate. Under the action of the synchronous pulley and synchronous belt, multiple lint grids are flipped over, with the side containing lint turning inward. This creates a partition through the lint grids, preventing negative pressure adsorption from affecting normal production. At the same time, it achieves automatic adsorption and collection of lint, reducing cleaning difficulty. In addition, through double-sided adsorption, uninterrupted adsorption can be achieved. With this structure, automatic collection of lint is achieved without affecting normal production, reducing the workload of workers and facilitating the secondary use of lint, thus reducing production costs.

[0064] In addition, during negative pressure collection, the stepper motor drives the turntable to rotate rapidly, causing multiple rubber rods to rotate and act on the inner wall of the felt board, separating the lint on the felt board. Under the action of the fan, air is continuously delivered to blow up the lint, which is then guided by the sliding chamber and acts sequentially on multiple felt boards, thus preventing the lint from adhering too tightly and ensuring thorough collection.

[0065] During operation, lint enters the collection box inside the negative pressure suction device through the suction head. When the collection box is removed, some lint may fly up due to the removal action, making collection difficult. By incorporating a membrane roll, which is hooked onto the clip frame before removal, the membrane roll unfolds simultaneously when the collection box is removed, covering the collection box with film. After complete extraction to ensure no lint flies up, the hook is removed, and the lint is then collected. This structure ensures the stability of lint collection and further reduces the difficulty of operation.

[0066] When using the aforementioned nonwoven fabric carding machine, the suction head of the negative pressure suction device attracts the flying lint, and the felt plate located between the suction head and the carding machine body automatically adsorbs the lint. The felt plate also acts as a barrier against the negative pressure, greatly reducing the impact of the negative pressure on the carding machine. Furthermore, the rotatable felt plate can achieve double-sided adsorption. While adsorbing on one side, the rubber rod driven by the turntable can clean the other side, greatly improving the continuity of adsorption and the cleaning process, thereby improving the overall work efficiency.
