Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabric splicing, and specifically relates to a non-waste automatic splicing device and method for non-woven fabrics. Background Art

[0002] The non-woven fabric splicing device, through an automatic control system and mechanical devices, precisely aligns and splices different rolls or batches of non-woven fabrics, and produces no waste or very little waste during the splicing process, thereby avoiding the defects that may occur in manual splicing and reducing the waste of raw materials.

[0003] In the prior art, generally through the hot melt splicing technology, seamless splicing of non-woven fabrics is achieved. To ensure the splicing quality, a small amount of material is usually fed at the splicing joint. Therefore, after splicing is completed, there is usually a small amount of fabric edge strip remaining. The current automatic collection method usually fixes one end of the edge strip and then winds it into the aggregate device. The edge strip can be easily separated by using the splicing temperature. However, due to the rich fibers on the fabric surface, when removing, it is very likely that the fibers will stick to the heating strip, affecting the effect of the next splicing.

[0004] In addition, after feeding the material currently, it is still necessary to manually spread the non-woven fabric so that it is laid flat on the surface of the heating strip. This not only has low efficiency, but also may cause the fingers of the staff to accidentally touch the heating strip during the flattening process and be scalded by the residual heat, posing a safety hazard.

[0005] Therefore, in view of this, the present invention proposes a non-waste automatic splicing device and method for non-woven fabrics to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0006] To solve the above technical problems, the present invention proposes a non-waste automatic splicing device and method for non-woven fabrics to solve the problems of fiber adhesion affecting splicing and low efficiency of manual spreading in the prior art.

[0010] Preferably, the aggregate trimming mechanism includes a support frame fixedly connected to the bottom of the hot pressing control box. The side of the support frame away from the hot pressing control box is fixedly connected to the machine body. A servo motor is fixedly connected to the side of the support frame away from the hot pressing control box. The output end of the servo motor rotatably penetrates the outer wall of the support frame and is fixedly connected to a reciprocating lead screw. A slider is threadedly connected to the outer wall of the reciprocating lead screw. One side outer wall of the slider is slidably connected to the support frame, and the other side outer wall of the slider is slidably connected to a collection box. The outer wall of the collection box is fixedly connected to the machine body.

[0011] Preferably, the aggregate trimming mechanism further includes a pressing block slidably connected to the top of the slider. A return spring is fixedly connected to the middle of the pressing block. The end of the return spring away from the pressing block is fixedly connected to the slider. An inclined groove is formed at the top edge of the slider, and a discharge port is formed on the side of the slider close to the collection box. The discharge port, the collection box, and the inclined groove are all interconnected.

[0012] Preferably, the aggregate trimming mechanism further includes a first gear rotatably connected to the inner wall of the middle of the slider. A rack plate is meshed with the outer wall of the first gear. The bottom of the rack plate is fixedly connected to the support frame, and a hot pressing strip is fixedly connected to the top of the rack plate. A hair scraping plate is fixedly connected to the top edge of the slider, and the outer wall of the hair scraping plate is slidably abutted against the surface of the hot pressing strip.

[0013] Preferably, the aggregate trimming mechanism further includes a main bevel gear fixedly connected to the top of the first gear. A sub-bevel gear is meshed with the outer wall of the main bevel gear. A second gear is fixedly connected to the center of the sub-bevel gear. A third gear is meshed with the outer wall of the second gear. The outer walls of the centers of the third gear, the second gear, the sub-bevel gear, and the main bevel gear are all rotatably connected to the inner wall of the slider.

[0014] Preferably, the aggregate trimming mechanism further includes aggregate rods rotatably connected to both sides of the third gear. A rubber head sleeve is fixedly connected to the bottom of a pair of the aggregate rods. The top of one of the aggregate rods rotatably penetrates the inner wall of the slider. A fan-shaped groove frame is fixedly connected to the top inner wall of the slider. The outer wall of the aggregate rod is slidably connected to the inner wall of the fan-shaped groove frame, and the outer wall of the other aggregate rod is slidably connected to the inner wall of the slider.

[0015] Preferably, the automatic flattening mechanism includes a plurality of electric push rods fixedly connected to the top of the support frame. A pressing strip pad is fixedly connected to the output ends of the plurality of electric push rods. A pair of V-shaped frames are rotatably connected to both sides of the pressing strip pad. One side of a pair of the V-shaped frames away from the pressing strip pad is movably connected to the support frame. Anti-slip pads are fixedly connected to the bottom edges of the V-shaped frames.

[0016] Preferably, the V-shaped frames are respectively located above both sides of the hot pressing strip.

[0017] Preferably, a pair of the aggregate rods are symmetrically arranged about the axis of the third gear. The aggregate rods are both L-shaped, and the bottom of the rubber head sleeve is arc-shaped.

[0018] A method for automatic splicing of waste-free non-woven fabrics comprises the following steps:

[0019] Step 1: Coil preparation: Workers overlap the fabric heads of two non-woven fabric coils to be spliced and place them together at the designated position of the equipment.

[0020] Step 2: Splicing operation: After the non-woven fabric coils are placed, the hot pressing control box will automatically start the splicing operation. Specifically, the edges of the two non-woven fabrics are connected together by hot pressing technology, so that the double-layer fabrics are melted and bonded together. At the same time, the automatic flattening mechanism will stretch and flatten the fabrics to both sides before the hot pressing operation to ensure the neatness of the fabrics.

[0021] Step 3: Waste treatment: For a very small amount of edge strip waste generated at the splicing site, the equipment will automatically collect and process it through the aggregate trimming mechanism to ensure the cleanliness and environmental protection of the production site and no waste generation.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. After hot melt splicing, through the setting of the aggregate trimming mechanism, a reciprocating slider is used as the drive, and finally the third gear is driven to rotate, so that the top of the aggregate rod makes an eccentric rotation on the outer wall of the third gear. Under the action of the gravity of the aggregate rod, a pair of aggregate rods make a reciprocating alternating swinging motion, and the rubber head sleeve at the bottom reciprocally adheres to and rubs against the surface of the fabric edge strip, continuously dialing the whole edge strip into the inclined groove of the slider. Then, in cooperation with the laterally moving scraping plate, a small amount of fabric edge strip residues on the side close to the collection box can be completely scraped off, automatically and efficiently collecting a small amount of waste of the edge strip, improving the recycling and treatment efficiency, making no waste generated in the working environment. At the same time, the double material removal of the aggregate rod and the scraping plate effectively avoids the adhesion of non-woven fabric fibers on the surface of the hot pressing strip, ensuring the splicing effect of the next time, and the scraping plate fits to scrape off the redundant fabric at the splicing site, enabling the splicing edge to be trimmed neatly and smoothly, achieving seamless splicing;

[0024] 2. When collecting waste, through the setting of the pressing block, during the pressing process of the pressing strip pad, the pressing block can be clamped on the top of the pressing strip pad for limiting. Under the limiting and pressing action of the pressing block, the pressure of the fabric between the pressing strip pad and the hot pressing strip is uniform, so its heating is more uniform, thereby improving the splicing quality;

[0025] 3. Through the setting of the automatic flattening mechanism, during the pressing process of the pressing strip pad, the top of the V-shaped frame can also be driven to press down, and the bottom continuously approaches the fabric. With the friction of the anti-slip pad, the two sides of the fabric can be pulled outwards to keep the fabric in a flat state. The staff only needs to place the fabric at the position of the hot pressing strip, without manually spreading the non-woven fabric, which improves the efficiency and reduces the safety hazards at the same time.

[0039] Embodiment 1 of the present invention

[0040] Please refer to Figures 1 to 10 as shown

[0041] To solve the problems mentioned in the technical solution, the embodiment of the present application provides a waste-free automatic splicing device for non-woven fabrics, including a machine body 1.

[0042] An aggregate trimming mechanism for automatically and efficiently collecting a small amount of waste of the side strip and pressurizing and removing the material;

[0043] An automatic flattening mechanism for automatically flattening the fabric during hot pressing;

[0044] The aggregate trimming mechanism includes a support frame 9 fixedly connected to the bottom of the hot pressing control box 3. One side of the support frame 9 away from the hot pressing control box 3 is fixedly connected to the machine body 1. A servo motor 13 is fixedly connected to one side of the support frame 9 away from the hot pressing control box 3. The output end of the servo motor 13 rotates through the outer wall of the support frame 9 and is fixedly connected to a reciprocating lead screw 20. A slider 12 is threadedly connected to the outer wall of the reciprocating lead screw 20. One side outer wall of the slider 12 is slidably connected to the support frame 9. The other side outer wall of the slider 12 is slidably connected to a collection box 15. The outer wall of the collection box 15 is fixedly connected to the machine body 1;

[0045] The aggregate trimming mechanism further includes a pressing block 16 slidably connected to the top of the slider 12. A reset spring 17 is fixedly connected to the middle of the pressing block 16. One end of the reset spring 17 away from the pressing block 16 is fixedly connected to the slider 12. An inclined groove is formed at the top edge of the slider 12. A discharge port 22 is formed on one side of the top of the slider 12 near the collection box 15. The discharge port 22, the collection box 15 and the inclined groove are all interconnected;

[0046] The aggregate trimming mechanism further includes a first gear 27 rotatably connected to the inner wall of the middle part of the slider 12. The outer wall of the first gear 27 is meshed with a rack plate 21. The bottom of the rack plate 21 is fixedly connected to the support frame 9. The top of the rack plate 21 is fixedly connected to a hot pressing strip 7. The top edge of the slider 12 is fixedly connected to a fluff scraping plate 18. The outer wall of the fluff scraping plate 18 is slidably abutted against the surface of the hot pressing strip 7.

[0047] The aggregate trimming mechanism further includes a main bevel gear 29 fixedly connected to the top of the first gear 27. The outer wall of the main bevel gear 29 is meshed with a sub-bevel gear 28. The center of the sub-bevel gear 28 is fixedly connected to a second gear 26. The outer wall of the second gear 26 is meshed with a third gear 25. The outer walls of the centers of the third gear 25, the second gear 26, the sub-bevel gear 28, and the main bevel gear 29 are all rotatably connected to the inner wall of the slider 12.

[0048] The aggregate trimming mechanism further includes aggregate rods 23 rotatably connected to both sides of the third gear 25. Both bottoms of the pair of aggregate rods 23 are fixedly connected with rubber head sleeves 24. The top of one aggregate rod 23 rotatably penetrates through the inner wall of the slider 12. The inner wall of the top of the slider 12 is fixedly connected with a fan-shaped groove frame 19. The outer wall of the aggregate rod 23 is slidably connected to the inner wall of the fan-shaped groove frame 19. The outer wall of the other aggregate rod 23 is slidably connected to the inner wall of the slider 12.

[0049] The pair of aggregate rods 23 are symmetrically arranged about the axis of the third gear 25. The aggregate rods 23 are both L-shaped. The bottom of the rubber head sleeve 24 is arc-shaped.

[0050] Wherein: the aggregate rod 23 is used for assisting in aggregating materials, and the pressing block 16 is used for limiting and boosting pressure.

[0051] The effects achieved by this embodiment are as follows: In the prior art, the automatic collection method usually uses one end of a fixed side strip and then winds it into the aggregate device. Due to the temperature of splicing, the side strip can be easily separated. However, since the surface of the fabric is rich in fibers, when removing the side strip, it is very likely that the fibers will adhere to the heating strip, affecting the effect of the next splicing. Compared with the prior art, through the implementation of this embodiment, the aggregate trimming mechanism can use the reciprocating slider 12 as a drive, and finally drive the third gear 25 to rotate, so that the top of the aggregate rod 23 makes an eccentric rotation on the outer wall of the third gear 25. Under the action of the gravity of the aggregate rod 23, the pair of aggregate rods 23 make a reciprocating alternating swinging motion. The rubber head sleeve 24 at the bottom reciprocally adheres to and rubs against the surface of the fabric side strip, continuously dialing the side strip as a whole into the inclined groove of the slider 12. Then, in cooperation with the laterally moving fluff scraping plate 18, the small amount of fabric side strip residues near the collection box 15 can be completely scraped off, automatically and efficiently collecting the small amount of waste of the side strip, improving the recycling and treatment efficiency, and making the working environment free of waste.

[0052] Further embodiment: Please refer to Figure 3, Figure 4 as shown

[0053] The automatic flattening mechanism includes a plurality of electric push rods 10 fixedly connected to the top of the support frame 9. The output ends of the plurality of electric push rods 10 are commonly fixedly connected with a pressure strip pad 11. A pair of V-shaped frames 8 are rotatably connected to both sides of the pressure strip pad 11. One side of the pair of V-shaped frames 8 away from the pressure strip pad 11 is movably connected to the support frame 9. Anti-slip pads 14 are fixedly connected to the bottom edges of the V-shaped frames 8;

[0054] The V-shaped frames 8 are respectively located above both sides of the hot pressure strip 7;

[0055] Wherein: chutes are provided at the joints of both sides of the support frame 9 and the V-shaped frames 8 to ensure the mobility of the V-shaped frames 8.

[0056] The effects achieved by this embodiment are as follows: In the prior art, after feeding, it is still necessary to manually spread the non-woven fabric so that it is flatly laid on the surface of the heating strip. This not only has low efficiency, but also may cause the fingers of the staff to accidentally touch the heating strip during the flattening process and be scalded by the residual heat, resulting in potential safety hazards. Compared with the prior art, through the implementation of this embodiment, by setting the automatic flattening mechanism, during the downward pressing of the pressure strip pad 11, the top of the V-shaped frame 8 can also be driven to press downward, and the bottom continuously approaches the fabric. With the friction of the anti-slip pads 14, the two sides of the fabric can be pulled outward to keep the fabric in a flat state. The staff only needs to place the fabric at the position of the hot pressure strip 7 without manually spreading the non-woven fabric.

[0057] Embodiment II of the present invention

[0058] A method for automatic splicing of non-woven fabric without waste includes the following steps:

[0059] Step 1: Coil preparation: The staff overlaps and overlaps the fabric heads of the two rolls of non-woven fabric coils to be spliced and places them together at the designated position of the equipment;

[0060] Step 2: Splicing operation: When the non-woven fabric coils are placed, the hot press control box 3 will automatically start the splicing operation. Specifically, the edges of the two rolls of non-woven fabric are connected together by a hot press process, so that the double-layer fabric melts and adheres together. At the same time, the automatic flattening mechanism will stretch and flatten the fabric to both sides before the hot press operation to ensure the neatness of the fabric;

[0061] Step 3: Waste treatment: For the very small amount of edge strip waste generated at the splicing joint, the equipment will automatically collect and process it through the aggregate trimming mechanism to ensure the cleanliness and environmental protection of the production site without waste generation.

[0062] The complete usage steps and working principles of the above embodiments are as follows:

[0063] In the initial state: The slider 12 is located on the side of the reciprocating lead screw 20 closer to the servo motor 13, the pressure strip pad 11 is in a position away from the hot pressing strip 7, and the return spring 17 is in a natural and relaxed state.

[0064] Working process:

[0065] During use, the staff places the overlapped two-layer fabric heads on the surface of the hot pressing strip 7 with their short sides facing the collection box 15. When the hot pressing control box 3 is started, the electric push rod 10 drives the pressure strip pad 11 to press the hot pressing strip 7, and the fabric on the surface of the hot pressing strip 7 is heated and melted. The double-layer fabric on the side away from the collection box 15 is adhesively spliced. A small amount of fabric side strip residues on the side close to the collection box 15 still need to be recycled. At this time, the device automatically starts the servo motor 13 according to the preset parameters, driving the reciprocating lead screw 20 to rotate, causing the slider 12 to reciprocate on the outer wall of the reciprocating lead screw 20. When the slider 12 moves, it can synchronously drive the first gear 27, causing the first gear 27 to rotate under the meshing action of the rack plate 21. The main bevel gear 29 is driven to rotate by the first gear 27, and then the secondary bevel gear 28 is driven to rotate by the main bevel gear 29, causing the vertically arranged second gear 26 to also rotate. Then the second gear 26 can drive the third gear 25 to rotate. Finally, the tops of a pair of aggregate rods 23 perform eccentric rotation on the outer wall of the third gear 25. Under the limiting action of the sector groove frame 19 and the slider 12, and the gravitational action of the aggregate rods 23, a pair of aggregate rods 23 perform reciprocating alternating swinging motions, so that the rubber head sleeves 24 at the bottoms of the aggregate rods 23 reciprocally adhere to and rub against the surface of the fabric side strips, continuously dialing the side strips into the inclined groove of the slider 12. Cooperating with the laterally moving scraping plate 18, the small amount of fabric side strip residues on the side close to the collection box 15 can be completely scraped off, collected in the inclined groove, and then discharged into the collection box 15 through the discharge port 22, completing the recycling of the side strips. The dual material removal not only accelerates the collection of residues but also effectively prevents non-woven fabric fibers from sticking to the surface of the hot pressing strip 7, ensuring the next splicing effect. And the scraping plate 18 fits and scrapes off the excess fabric at the splicing position, enabling the splicing edge to be neat and traceless;

[0066] Furthermore, during the downward pressing of the pressure strip pad 11, it can push the pressure block 16 to squeeze the return spring 17. Until the pressure strip pad 11 is close to the hot pressing strip 7, the pressure block 16 resets under the elastic force of the return spring 17 to limit the pressure strip pad 11. The reciprocating slider 12 can synchronously drive the pressure block 16. Therefore, under the limiting and pressurizing action of the pressure block 16, the pressure between the pressure strip pad 11 and the hot pressing strip 7 on the fabric is uniform, and thus the heating is more uniform, ensuring the splicing quality and making it easier to separate the residues;

[0067] Please refer to the above working process Figures 1 to 3 、 Figures 5 to 10 。

[0068] Furthermore, when the caulking pad 11 is pressed downwards, it can also drive the tops of the V-shaped frames 8 on both sides to press downwards, so that the anti-slip pads 14 at the bottoms of the V-shaped frames 8 continuously approach the fabric. At the same time, the mutually separated sides of the two V-shaped frames 8 abut against the support frame 9 and rotate, and slide in the chute. Through the external cutting force of the V-shaped frames 8 on both sides and the frictional force of the anti-slip pads 14, the two sides of the fabric can be pulled outwards to keep the fabric in a flat state, ensuring that the splicing joint of the fabric is flat and traceless. There is no need for manual spreading of the non-woven fabric. After splicing and waste material collection are completed, the coiled material can be directly and automatically wound into the main non-woven fabric through the transfer roller 4, and the newly replaced coiled material can continuously feed at the feeding roller 2, improving the degree of automation;

[0069] Please refer to the above working process Figures 3 to 4 。

[0070] The circuits and controls involved in the present invention are all prior arts and will not be elaborated here too much.

The scope of the present invention is defined by the appended claims and their equivalents.

7. A method for automatic splicing of non-woven fabrics without waste, applied to the non-woven fabric waste-free automatic splicing equipment according to any one of claims 1-6, characterized in that, It includes the following steps: Step 1: Coil preparation: The staff overlaps and overlaps the cloth heads of two rolls of non-woven fabric coils to be spliced and places them together at the designated position of the non-waste automatic splicing equipment for non-woven fabric. Step 2: Splicing operation: When the non-woven fabric coils are placed, the hot pressing control box (3) will automatically start the splicing operation. Specifically, the edges of the two rolls of non-woven fabric are connected together through the hot pressing process, causing the double-layer cloth to melt and bond together. At the same time, the automatic flattening mechanism will stretch and flatten the cloth to both sides before the hot pressing operation to ensure the neatness of the cloth. Step 3: Waste treatment: For the extremely small amount of edge strip waste generated at the splicing joint, the non-waste automatic splicing equipment for non-woven fabric automatically collects and treats it through the aggregate trimming mechanism to ensure the cleanliness and environmental protection of the production site without waste generation.
