Description

Technical Field

[0001] The invention relates to the technical field of non-woven fabric splicing, and in particular to a non-woven fabric waste-free automatic splicing device and a method thereof. Background Art

[0002] The non-woven fabric splicing equipment uses an automated control system and mechanical devices to accurately align and splice non-woven fabrics from different rolls or batches, and produces no or very little waste during the splicing process, thereby avoiding the defects that may be caused by manual splicing and reducing the waste of raw materials;

[0003] In the prior art, hot melt splicing technology is generally used to make non-woven fabrics seamlessly spliced. In order to ensure the quality of splicing, it is usually necessary to release a small amount of material from the splicing joint. Therefore, after the splicing is completed, a small amount of fabric edge strips will usually remain. The current automatic collection method usually uses one end of the fixed edge strip and then rolls it into a collection device. The edge strips can be easily separated by the splicing temperature. However, due to the rich fibers on the surface of the fabric, the fibers are likely to stick to the heating strip when removing them, affecting the effect of the next splicing.

[0004] In addition, after loading, the non-woven fabric needs to be spread manually so that it can be laid evenly on the surface of the heating strip. This is not only inefficient, but may also cause the workers' fingers to accidentally touch the heating strip during the laying process, causing burns from the residual heat, posing a safety hazard.

[0005] In view of this, the present invention proposes a non-woven fabric waste-free automatic splicing device and method thereof to make up for and improve the deficiencies of the prior art. Summary of the invention

[0020] Step 2: Splicing operation: When the non-woven fabric rolls are placed, the hot pressing control box will automatically start the splicing operation, which is to connect the edges of the two rolls of non-woven fabrics together through the hot pressing process, so that the double layers of fabrics are melted and bonded together.

After hot-melt splicing, the material collecting and trimming mechanism is set up, and a reciprocating slider is used as a drive, and finally the third gear is driven to rotate, so that the top of the collecting rod rotates eccentrically on the outer wall of the third gear. Under the gravity of the collecting rod, a pair of collecting rods swing back and forth alternately, and the rubber head cover at the bottom reciprocates and rubs against the surface of the fabric edge strip, and the edge strip is continuously pushed into the inclined groove of the slider. In combination with the horizontally moving scraper plate, a small amount of fabric edge strip residue near one side of the collection box can be completely scraped off, and a small amount of waste material of the edge strip can be automatically and efficiently collected, so as to improve the recycling efficiency and make the working environment free of waste. At the same time, the double material removal of the collecting rod and the scraper plate effectively prevents the non-woven fabric fibers from sticking to the surface of the hot pressing strip, ensuring the next splicing effect, and the scraper plate scrapes away the excess fabric at the splicing, so that the splicing edge can be trimmed and seamlessly spliced;

[0024] 2. When collecting waste materials, the pressure block can be set to limit the top of the pressure pad during the pressing process of the pressure pad. Under the limiting and pressurizing effect of the pressure block, the pressure of the fabric between the pressure pad and the hot pressure strip can be uniform, so that the heat is more uniform, thereby improving the splicing quality;

[0025] 3. Through the setting of the automatic flattening mechanism, when the pressure strip pad is pressed down, the top of the V-shaped frame can also be pressed down, and the bottom keeps approaching the cloth. With the friction of the anti-slip pad, the two sides of the cloth can be pulled outward to keep the cloth flat. The staff only needs to place the cloth on the position of the hot pressure strip, and there is no need to manually spread the non-woven fabric, which improves efficiency while reducing safety hazards.

[0050] Among them: the collecting rod 23 is used for auxiliary material collection, and the pressing block 16 is used for limiting and increasing 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 edge strip, which is then rolled into a collection device. The edge strip can be easily separated by using the temperature of the splicing. However, due to the rich fibers on the surface of the cloth, the fibers are likely to stick to the heating strip when being removed, affecting the effect of the next splicing.

[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 to a layering pad 11, and a pair of V-shaped frames 8 are rotatably connected to both sides of the layering pad 11, and the sides of the pair of V-shaped frames 8 away from the layering pad 11 are movably connected to the support frame 9, and the bottom edges of the V-shaped frames 8 are fixedly connected to anti-slip pads 14;

[0054] The V-shaped frames 8 are respectively located above the two sides of the heat pressing strip 7;

[0055] Wherein: sliding grooves are provided at the connection places between the two sides of the support frame 9 and the V-shaped frame 8 to ensure the mobility of the V-shaped frame 8.

[0056] The effects achieved by this embodiment are as follows: In the prior art, after loading, the non-woven fabric needs to be spread manually so that it can be laid flat on the surface of the heating strip, which is not only inefficient, but also may cause the staff's fingers to accidentally touch the heating strip during the laying process, and be burned by the residual temperature, causing safety hazards. Compared with the prior art, through the implementation of this embodiment, an automatic flattening mechanism is set up to be able to drive the top of the V-shaped frame 8 to press down during the pressing process of the pressure strip pad 11, and the bottom continues to approach the fabric. With the friction force of the anti-slip pad 14, the two sides of the fabric can be pulled outward to keep the fabric flat. The staff only needs to place the fabric on the position of the hot pressure strip 7, and there is no need to manually spread the non-woven fabric.

[0057] Embodiment 2 of the present invention

[0058] The method for automatically splicing non-woven fabrics without waste comprises the following steps:

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

[0060] Step 2: Splicing operation: After the non-woven fabric rolls are placed, the hot pressing control box 3 will automatically start the splicing operation, specifically connecting the edges of the two rolls of non-woven fabrics together through a hot pressing process, so that the double layers of fabrics are melted and bonded together. At the same time, the automatic flattening mechanism will stretch the fabric to both sides and flatten it before the hot pressing 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 joints, the equipment will automatically collect and process it through the aggregate trimming mechanism to ensure a clean and environmentally friendly production site without waste generation.

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

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

[0064] Working process:

[0065] When in use, the staff places the overlapping two layers of cloth heads on the surface of the hot pressing strip 7, and makes their short sides face the position of the collecting box 15. When the hot pressing control box 3 is started, the electric push rod 10 drives the pressing strip pad 11 to press the hot pressing strip 7, and the cloth on the surface of the hot pressing strip 7 is heated and melted. The double-layer cloth on the side away from the collecting box 15 is bonded and spliced, while a small amount of cloth edge strip residue on the side close to the collecting box 15 needs to be recycled. At this time, the equipment automatically starts the servo motor 13 according to the preset parameters, drives the reciprocating screw 20 to rotate, so that the slider 12 slides back and forth on the outer wall of the reciprocating screw 20. When the slider 12 moves, it can synchronously drive the first gear 27, so that the first gear 27 rotates under the meshing action of the rack plate 21, and the main bevel gear 29 is driven to rotate by the first gear 27, and then the auxiliary bevel gear 28 is driven to rotate by the main bevel gear 29, so that the vertically arranged second gear 26 also rotates, and then the second gear The wheel 26 can drive the third gear 25 to rotate, and finally make the top of a pair of collecting rods 23 rotate eccentrically on the outer wall of the third gear 25. Under the limiting effect of the fan-shaped slot frame 19 and the slider 12, and the gravity of the collecting rod 23, the pair of collecting rods 23 perform reciprocating and alternating swinging motions, so that the rubber head cover 24 at the bottom of the collecting rod 23 reciprocates and rubs against the surface of the fabric edge strip, and the edge strip is continuously pushed into the inclined groove of the slider 12 as a whole. In combination with the scraper plate 18 that moves laterally, a small amount of fabric edge strip residue near one side of the collection box 15 can be completely scraped off, collected into the inclined groove, and then discharged into the collection box 15 through the discharge port 22, completing the recycling of the edge strip. The double 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 scraper plate 18 fits and scrapes away the excess fabric at the splicing, so that the splicing edge can be neat and traceless.

[0066] Furthermore, during the process of pressing down the pressure strip pad 11, the pressing block 16 can be pushed to squeeze the reset spring 17 until the pressure strip pad 11 is close to the hot pressure strip 7. The pressing block 16 is reset under the elastic force of the reset spring 17 to limit the pressure strip pad 11. The reciprocating slider 12 can synchronously drive the pressing block 16. Therefore, under the limiting and pressurizing action of the pressing block 16, the pressure of the fabric between the pressure strip pad 11 and the hot pressure strip 7 can be uniform, thereby making the heating more uniform, ensuring the splicing quality, and making it easier to separate the residual material.

[0067] Please refer to the above working process Figures 1 to 3 , Figures 5 to 10 .

[0068] Furthermore, when the pressure strip pad 11 is pressed down, the tops of the V-shaped frames 8 on both sides can also be driven to press down, so that the anti-skid pad 14 at the bottom of the V-shaped frame 8 is constantly approaching the cloth, and at the same time, the two sides of the V-shaped frames 8 that are away from each other are abutted on the support frame 9 to rotate and slide in the slide groove. Through the external shear force of the V-shaped frames 8 on both sides and the friction force of the anti-skid pad 14, the two sides of the cloth can be pulled outward to keep the cloth flat, ensuring that the cloth splicing is flat and traceless, without manual spreading of the non-woven fabric. After the splicing and the collection of the residual materials are completed, the coiled material can be automatically rolled into the main roll of non-woven fabric through the transfer roller 4, so that the newly replaced coiled material can be continuously discharged at the feeding roller 2, thereby improving the degree of automation;

[0069] Please refer to the above working process Figure 3 to Figure 4 .

The non-woven fabric waste-free automatic splicing equipment according to claim 6, characterized in that: A pair of the collecting rods (23) are centrally symmetrically arranged with the axis of the third gear (25) as the center of the circle, the collecting rods (23) are all arranged in an L shape, and the bottom of the rubber head cover (24) is arranged in an arc shape.

10. A method for automatically splicing non-woven fabrics without waste, applied to the automatic splicing device for automatically splicing non-woven fabrics without waste according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Coil preparation: The staff overlaps the fabric heads of the two rolls of non-woven fabric to be spliced ​​and places them together at the position specified by the equipment; Step 2: Splicing operation: After the non-woven fabric rolls are placed, the hot pressing control box (3) will automatically start the splicing operation, specifically connecting the edges of the two rolls of non-woven fabrics together through a hot pressing process, so that the double layers of fabrics are melted and bonded together. At the same time, the automatic flattening mechanism will stretch the fabrics to both sides and flatten them before the hot pressing operation to ensure the neatness of the fabrics. Step 3: Waste treatment: For the very small amount of edge strip waste generated at the splicing point, the equipment automatically collects and treats it through the aggregate trimming mechanism to ensure the cleanliness and environmental protection of the production site without waste generation.
