Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric feeding technology, and more specifically to a nonwoven fabric feeding mechanism. Background Technology

[0002] Wet wipes are a common daily necessity in our lives. Their cleaning ability is stronger than that of most dry wipes, which is why they are widely popular. Wet wipes are mainly composed of a base material and a liquid. The base material is mostly non-woven fabric. When making wet wipes, non-woven fabric base material needs to be folded and cut. Before these processes, special feeding equipment is generally needed to transport the non-woven fabric to the corresponding feeding port.

[0003] Currently, the non-woven fabric raw materials purchased by wet wipe manufacturers are generally in rolls. The feeding equipment mainly unrolls the non-woven fabric and conveys it along a designated path. Conventional conveying equipment generally consists of a roller and a drive mechanism that controls the rotation of the roller. During feeding, the roll of non-woven fabric substrate is fixedly placed on the roller, and then the end of the rolled non-woven fabric is pulled to the feed port of the back-end processing equipment. Then, the drive mechanism drives the roller to rotate, so that the non-woven fabric can be continuously conveyed to the back-end equipment, thus realizing feeding.

[0004] However, the aforementioned equipment still has certain drawbacks during use. The rolled nonwoven fabric substrate has a certain length, and after it is fully unrolled, a new roll of nonwoven fabric needs to be replaced. At this time, the supply of material to the downstream equipment will be interrupted, thereby affecting the production cycle and production efficiency. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a nonwoven fabric feeding mechanism to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: a nonwoven fabric feeding mechanism, comprising: a frame; idlers, which are rotatably mounted on the frame, on which nonwoven fabric rolls can be fitted and rotate synchronously with the idlers, and there are at least two sets of idlers; a docking assembly, which is mounted on the frame and located between the two sets of idlers, wherein the beginning ends of the nonwoven fabric rolls on the two sets of idlers are aligned and pass through the middle of the docking assembly, and the beginning end of one of the nonwoven fabric rolls flows into the feed port of the rear equipment, and when the nonwoven fabric roll is released, the docking assembly will neatly connect the beginning end of the nonwoven fabric on the other set of idlers with the end end of the released nonwoven fabric roll.

[0007] Furthermore, the docking assembly includes a mating plate and guide rollers. A support frame is fixedly installed on the side of the frame, and the mating plate is slidably mounted on the support frame. There are two sets of mating plates and guide rollers, which are arranged opposite to each other. The beginning ends of the nonwoven fabric rolls on the two rollers pass between the two mating plates, and the beginning end of one nonwoven fabric roll is connected to the rear end equipment, while the beginning end of the other nonwoven fabric roll is placed on the mating plate. At the same time, the sliding of the mating plate can make the two sections of nonwoven fabric fit together. The guide rollers are rotatably mounted on the side of the frame, and the nonwoven fabric strips released from the two nonwoven fabric rolls are respectively mounted on the surface of the two guide rollers. The two sets of mating plates are each equipped with a power assembly, and the mating plates are driven to slide by the power assembly.

[0008] Furthermore, the power assembly includes a cylinder, a swing arm, a connecting rod, and a guide column. The guide column is slidably mounted on the support frame, and the plate is fixedly connected to the end of the guide column. The swing arm is rotatably mounted on the side of the support frame. One end of the connecting rod is rotatably connected to the end of the swing arm away from its rotation center, and the other end is rotatably connected to the end of the guide column away from the plate. This allows the swing arm to rotate and drive the guide column to slide through the connecting rod. The cylinder is rotatably mounted on the frame, and a control rod is rotatably mounted on the movable end of the cylinder. The end of the control rod away from the movable end of the cylinder is fixedly connected to the swing arm's pivot shaft, and when the movable end of the cylinder moves, it drives the swing arm to rotate through the control rod.

[0009] 4. A nonwoven fabric feeding mechanism according to claim 3, characterized in that: a retaining ring is fixedly installed on the surface of the guide column, a compression spring is installed between the retaining ring and the support frame, and the compression spring is sleeved on the guide column. At the same time, when the guide column slides to drive the bonding plate to adhere to the nonwoven fabric, it will simultaneously drive the retaining ring to squeeze the compression spring.

[0010] Furthermore, a protective cover is fixedly installed on the surface of the support frame, which covers the support frame and the power components.

[0011] Furthermore, the docking assembly also includes a sensing component, which is mounted on the frame and contacts the nonwoven fabric roll on the idler roller. The sensing component can detect the thickness of the nonwoven fabric roll on the idler roller and trigger to give the cylinder a working signal when the nonwoven fabric roll is completely released.

[0012] Furthermore, the sensing component includes a support shaft, a mounting plate, and an infrared sensor. The support shaft is fixedly mounted on the frame, and the mounting plate is rotatably mounted on the support shaft and mounted on the surface of the nonwoven fabric roll on the roller. A window is opened on the mounting plate, and the infrared sensor is fixedly mounted on the surface of the mounting plate, with the sensing end pointing from the window to the surface of the nonwoven fabric roll. At the same time, when the infrared sensor is triggered, it will give a start signal to the control circuit of the cylinder.

[0013] Furthermore, the docking assembly also includes a cutting assembly, which cuts the nonwoven fabric between the connection point of the two nonwoven fabric strips and the end of the released nonwoven fabric roll when the two nonwoven fabric strips are connected.

[0014] Furthermore, the cutting assembly includes a roller, a cutter, and an anvil. The roller is mounted on the side of the support frame, and the roller's rotation axis is coaxially connected to the swing arm's rotation axis and rotates synchronously with it. The cutter is fixedly mounted on the surface of the roller, and the anvil is mounted on the side of the support frame and below the roller. The nonwoven fabric strip mounted on the guide roller passes between the roller and the anvil, and the rotation of the roller will drive the cutter to cut the nonwoven fabric strip between the roller and the anvil.

[0015] The present invention also provides a method for feeding nonwoven fabric, based on a nonwoven fabric feeding mechanism according to any one of claims 1-9, the method comprising: S1: Secure the non-woven fabric roll onto the idler roller; S2: Pull out the first end of the non-woven fabric roll on the idler roller, so that it passes in sequence through the gap between the roller shaft and the anvil, the surface of the guide roller, and between the two mating plates; S3: Insert a strip of nonwoven fabric that passes between the two mating plates into the feed port of the back-end equipment.

[0016] The technical effects and advantages of this invention are as follows: This invention, by setting a connecting component, can automatically continue a new nonwoven fabric roll at its tail end when a section of nonwoven fabric roll is released, thereby achieving continuous feeding and effectively improving production efficiency. In addition, during the continuation process, the redundant "old" nonwoven fabric outside the connection point of the two sections of nonwoven fabric will be automatically cut off, reducing the connection point and minimizing interference with downstream production equipment.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative and are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1-7 This invention provides a nonwoven fabric feeding mechanism, comprising: a frame 1, idler rollers 2, and a docking assembly 3; the idler rollers 2 are rotatably mounted on the frame 1, and nonwoven fabric rolls can be fitted onto the idler rollers 2 and rotate synchronously with the idler rollers 2, and there are at least two sets of idler rollers 2; the docking assembly 3 is mounted on the frame 1 and is located between the two sets of idler rollers 2, and the beginning ends of the nonwoven fabric rolls on the two sets of idler rollers 2 are aligned and pass through the middle of the docking assembly 3, and the beginning end of one of the nonwoven fabric rolls flows into the feed port of the rear equipment, and when the nonwoven fabric roll is released, the docking assembly 3 will neatly connect the beginning end of the nonwoven fabric on the other set of idler rollers 2 with the end end of the released nonwoven fabric roll.

[0021] When using the above-mentioned feeding mechanism, simply first place a non-woven fabric roll on each of the two idler rollers 2 and fix it on the idler roller 2 so that it rotates with the idler roller 2. The idler roller 2 can be a commonly available tensioning shaft to achieve the above function. Then, pull out non-woven fabric strips from the two non-woven fabric rolls and pass them through the middle of the docking assembly 3. Connect one of them to the feed port of the back-end equipment, and temporarily mount the other on the docking assembly 3. When this step is completed, it is necessary to keep the two non-woven fabric strips in the docking assembly 3 aligned. This can be achieved by... Alignment of the two rollers 2 is achieved. Then, a piece of double-sided tape is cut and one side is attached to the surface of the nonwoven fabric mounted on the docking component 3. At this time, after the nonwoven fabric roll connected to the rear feed port is released, the docking component 3 will drive the two nonwoven fabric strips to stick together, thereby connecting the two nonwoven fabrics. Then, the previously used nonwoven fabric roll is replaced and a new one is installed. The first end is pulled out and passed through the docking component 3 and finally mounted on the docking component 3 to achieve continuous nonwoven fabric supply.

[0022] It should be noted that the joints of the non-woven fabric at both ends will be manually removed during subsequent processing and will not affect the finished wet wipes.

[0023] The docking assembly 3 includes a mating plate 31 and a guide roller 32. A support frame 33 is fixedly installed on the side of the frame 1. The mating plate 31 is slidably installed on the support frame 33. There are two sets of mating plates 31 and guide rollers 32, which are arranged opposite to each other. The beginning ends of the nonwoven fabric rolls on the two rollers 2 pass through the two mating plates 31. The beginning end of one nonwoven fabric roll is connected to the rear end equipment, and the beginning end of the other nonwoven fabric roll is placed on the mating plate 31. At the same time, the sliding of the mating plate 31 can make the two sections of nonwoven fabric fit together. The guide roller 32 is rotatably installed on the side of the frame 1. At the same time, the nonwoven fabric strips released from the two nonwoven fabric rolls are respectively mounted on the surface of the two guide rollers 32. The two sets of mating plates 31 are respectively equipped with a power assembly 34, and the mating plates 31 are driven to slide by the power assembly 34.

[0024] In this way, simply pass the non-woven fabric strips through the two mating plates 31 in alignment, and attach double-sided tape to the alternative non-woven fabric strip at the position aligned with the mating plate 31. Then, when it is necessary to continue the non-woven fabric, simply drive the mating plate 31 to move through the power component 34, which will cause the two non-woven fabric strips to stick together to achieve the continuation.

[0025] The power assembly 34 includes a cylinder 341, a swing arm 342, a connecting rod 343, and a guide column 344. The guide column 344 is slidably mounted on the support frame 33 and is fixedly connected to the end of the plate 31. The swing arm 342 is rotatably mounted on the side of the support frame 33. One end of the connecting rod 343 is rotatably connected to the end of the swing arm 342 away from its rotation center, and the other end is rotatably connected to the end of the guide column 344 away from the plate 31. This allows the swing arm 342 to rotate and drive the guide column 344 to slide through the connecting rod 343. The cylinder 341 is rotatably mounted on the frame 1, and a control rod 345 is rotatably mounted on the movable end of the cylinder 341. The end of the control rod 345 away from the movable end of the cylinder 341 is fixedly connected to the pivot of the swing arm 342. This allows the swing arm 342 to rotate through the control rod 345 when the movable end of the cylinder 341 moves.

[0026] Thus, when it is necessary to drive the mating plate 31 to move, simply start the cylinder 341, so that its movable end drives the control rod 345 to rotate. The control rod 345 will drive the swing arm 342 to rotate, and the swing arm 342 will drive the guide column 344 to slide through the connecting rod 343, thereby driving the mating plate 31 to slide to achieve the bonding and connection of the two sections of non-woven fabric.

[0027] A retaining ring 346 is fixedly installed on the surface of the guide post 344. A compression spring 347 is installed between the retaining ring 346 and the support frame 33. The compression spring 347 is sleeved on the guide post 344. When the guide post 344 slides and drives the bonding plate 31 to bond with the non-woven fabric, it will simultaneously drive the retaining ring 346 to squeeze the compression spring 347.

[0028] Thus, after the two sections of nonwoven fabric are connected, if the cylinder 341 is damaged, the compression spring 347 will also reset and cause the mating plate 31 to separate, thereby ensuring that the nonwoven fabric is not clamped by the mating plate 31 and the feeding is not interrupted, further ensuring the feeding stability.

[0029] A protective cover 348 is fixedly installed on the surface of the support frame 33, which covers the support frame 33 and the power assembly 34. This can prevent other interfering objects from entering the power assembly 34 and further ensure operational stability.

[0030] The docking assembly 3 also includes a sensing assembly 35, which is mounted on the frame 1 and contacts the nonwoven fabric roll on the idler roller 2. The sensing assembly 35 can detect the thickness of the nonwoven fabric roll on the idler roller 2 and trigger it to give the cylinder 341 a working signal when the nonwoven fabric roll is completely released.

[0031] The sensing component 35 includes a support shaft 351, a mounting plate 352, and an infrared sensor 353. The support shaft 351 is fixedly mounted on the frame 1, and the mounting plate 352 is rotatably mounted on the support shaft 351 and mounted on the surface of the nonwoven fabric roll on the roller 2. A window is provided on the mounting plate 352, and the infrared sensor 353 is fixedly mounted on the surface of the mounting plate 352, with the sensing end pointing from the window to the surface of the nonwoven fabric roll. When the infrared sensor 353 is triggered, it will give a start signal to the control circuit of the cylinder 341.

[0032] Thus, as the nonwoven fabric roll is continuously released until it is finished, the infrared sensing line emitted by the infrared sensor 353 will gradually move from tilted to horizontal. When it is close to horizontal, the nonwoven fabric roll is finished being released. At this time, the sensing end of the infrared sensor 353 will be unobstructed, which will trigger the cylinder 341 to work and drive the cylinder 341 to move. In this way, automatic operation can be achieved.

[0033] The docking assembly 3 also includes a cutting assembly 36, which cuts the nonwoven fabric between the connection point of the two nonwoven fabric strips and the end of the released nonwoven fabric roll when the two nonwoven fabric strips are connected. The cutting assembly 36 includes a roller 361, a cutter 362, and an anvil 363. The roller 361 is mounted on the side of the support frame 33, and the rotation axis of the roller 361 is coaxially connected to the rotation axis of the swing arm 342 and rotates synchronously with it. The cutter 362 is fixedly mounted on the surface of the roller 361. The anvil 363 is mounted on the side of the support frame 33 and is located below the roller 361. The nonwoven fabric strip mounted on the guide roller 32 passes between the roller 361 and the anvil 363, and the rotation of the roller 361 will drive the cutter 362 to cut the nonwoven fabric strip between the roller 361 and the anvil 363.

[0034] Thus, before the nonwoven fabric passes through the two bonding plates 31, it must pass through the gap between the cutter 362 and the anvil 363. In this way, when connecting the two sections of nonwoven fabric, the rotation of the swing arm 342 will drive the roller 361 to rotate, which in turn drives the cutter 362 to fit with the anvil 363. This will cut the nonwoven fabric between the cutter 362 and the anvil 363, thereby avoiding excessive redundant nonwoven fabric strips being dragged outside the connection point of the two sections of nonwoven fabric, reducing the difficulty of subsequent manual removal, and ensuring that the back-end equipment can work smoothly.

[0035] Therefore, the complete usage process is as follows: First, place a non-woven fabric roll on each of the two idler rollers 2 and fix it on the idler rollers 2 so that it rotates with the idler rollers 2. Then, pull out non-woven fabric strips from the two non-woven fabric rolls and pass them evenly between the two mating plates 31. Connect one of them to the feed port of the back-end equipment, and temporarily mount the other on the protective cover 348 as a backup. Apply double-sided tape to the backup non-woven fabric strip at the position aligned with the mating plate 31. Then, when it is necessary to continue the non-woven fabric, that is, when the infrared sensor 353 is triggered, the cylinder 341 will start, and its movable end will drive the control rod 345 to rotate. The control rod 345 The swing arm 342 will rotate, and the swing arm 342 will drive the guide column 344 to slide through the connecting rod 343, thereby driving the mating plate 31 to slide to achieve the bonding and connection of the two non-woven fabrics. Before the non-woven fabric passes through the two mating plates 31, it must pass through the gap between the cutter 362 and the anvil 363. In this way, when connecting the two non-woven fabrics, the rotation of the swing arm 342 will drive the roller 361 to rotate, thereby driving the cutter 362 to bond with the anvil 363. This will cut the non-woven fabric between the cutter 362 and the anvil 363, thus avoiding excessive redundant non-woven fabric strips being dragged outside the connection point of the two non-woven fabrics.

[0036] In summary, the entire feeding mechanism can continuously feed non-woven fabric to the back end during use, enabling continuous production of the back-end equipment and effectively improving production efficiency.

[0037] In the above solution, double-sided tape needs to be manually applied each time two sections of non-woven fabric are connected, which is undoubtedly very tedious. Therefore, further optimization is needed: The mounting plate 31 includes a fixed plate 311 and a movable plate 312. The fixed plate 311 is fixedly connected to the guide post 344. A groove is provided on the side of the fixed plate 311 away from the guide post 344. The movable plate 312 is slidably installed in the groove. A receiving groove 313 is machined on the surface of the movable plate 312 away from the fixed plate 311. A number of staples are installed in the receiving groove 313. A top piece 314 is fixedly installed in the movable plate 312. A cover plate 315 is provided for the receiving groove 313. The cover plate 315 is detachably fixed to cover the receiving groove 313 by screws. At the same time, a through groove is machined in both the cover plate 315 and the receiving groove 313. The size of the through groove corresponds to the width of a staple. The top piece 314 can be inserted into the through groove and push out the staples aligned with the cover plate 315 from the through groove.

[0038] A return spring 316 is connected between the movable plate 312 and the groove. When the movable plate 312 is fixed and the guide post 344 drives the fixed plate 311 to move, it stores energy and releases it when the two mating plates 31 are separated, so that the side of the movable plate 312 that is close to the fixed plate 311 moves away from the fixed plate 311, that is, the top piece 314 slides out from the cover plate 315.

[0039] A slider 317 is slidably provided in the receiving groove 313. A top spring 318 is connected between the slider 317 and the inner wall of the receiving groove 313. The top spring 318 can push the slider to slide, and the slider 317 will push the staple to slide to ensure that there is always a staple aligned with the cover plate 315. The cover plates 315 on the two mating plates 31 are staggered, and the surface of the movable plate 312 opposite the cover plate 315 is concave, which allows the two staple teeth to bend better.

[0040] Thus, when the two mating plates 31 are mated, the two movable plates 312 will first come into contact. At this time, the two movable plates 312 will mat the two sections of non-woven fabric that need to be connected together. Then, the guide post 344 will continue to move, thereby driving the fixed plate 311 to move. This will drive the top piece 314 to move to insert into the through groove and push out a staple. This staple will pierce the overlapping part of the two sections of non-woven fabric, and then bend under the limiting action of the opposite movable plate 312. In this way, the two sections of non-woven fabric can be nailed together, thereby achieving connection. In this structure, since the receiving groove 313 can accommodate multiple staples, the user does not need to frequently apply tape, thus effectively simplifying the operation and further facilitating use.

[0041] The present invention also provides a method for feeding nonwoven fabric, based on a nonwoven fabric feeding mechanism according to any one of claims 1-9, the method comprising: S1: Secure the non-woven fabric roll onto the idler roller 2; S2: Pull out the first end of the non-woven fabric roll on the idler roller 2, so that it passes in sequence through the gap between the roller shaft 361 and the anvil 363, the surface of the guide roller 32, and between the two mating plates 31. S3: Insert a strip of nonwoven fabric that passes between the two mating plates 31 into the feed port of the back-end equipment.

[0042] Using this method for nonwoven fabric feeding can ensure a continuous supply of nonwoven fabric to the back-end equipment, effectively improving production efficiency.

[0043] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this invention only involve the structures involved in the embodiments disclosed in this invention.
