Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and more specifically, to a fabric edge cutting device. Background Technology

[0002] During the fabric coating process, it is necessary to thoroughly cut the allowance edge. This operation not only ensures that the fabric size meets the set requirements, but also makes the fabric edge neat and smooth, thereby improving the quality and appearance of the fabric.

[0003] Currently, in order to recycle the cut strips, a collection basket is usually placed under the cutter, so that the cut strips fall into the basket under the force of gravity and accumulate.

[0004] However, once the basket is full, the cutting strips need to be cut manually to remove the long strips from the basket. But since the fabric is transported continuously, this method is limited by the volume of the basket and requires frequent cleaning, which is time-consuming and labor-intensive. Moreover, since the basket is close to the equipment that transports the fabric and this equipment is in motion, it is easy to touch the equipment during the collection of the cutting strips, which could lead to a safety accident. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a fabric cutting edge strip device, designed to automatically collect the cut edge strips, improving collection efficiency and safety.

[0006] A fabric edge-cutting device according to an embodiment of the present invention includes a conveyor belt, a first cutting component, a first adsorption component, a second cutting component, and a second adsorption component. A roller of the conveyor belt has a corner section, the corner section having a first side and a second side. The conveyor belt is used to transport fabric. The first cutting component is located on the first side and is used to cut the edge of the fabric to form a cut edge strip. The first adsorption component is located on the second side and has a cyclically rotating adhesive portion that can generate negative pressure for adsorbing the cut edge strip. The second cutting component... The component is located on the second side and has a cutting part. The second cutting component is tractively connected to the first adsorption component. The second adsorption component is provided with an openable and closable first vacuum nozzle for adsorbing and pulling the cut edge strip on the side close to the first adsorption component. When the bonding part rotates, the cutting part periodically presses against and moves away from the bonding part. When the cut edge strip adsorbed on the bonding part is cut by the cutting part, a part of the bonding part stops generating negative pressure, so that the first vacuum nozzle can pull the cut edge strip. When the cutting part moves away from the bonding part, the area corresponding to the bonding part generates negative pressure again.

[0007] According to some embodiments of the present invention, the first adsorption component includes a partition, an annular steel belt, a plurality of second vacuum nozzles, and a driving component. The annular steel belt is rotatably disposed on the partition and is sealed between the annular steel belt and the partition to form an air cavity. The annular steel belt array is provided with air holes. The plurality of second vacuum nozzles are all disposed in the air cavity. The second vacuum nozzles face the side of the annular steel belt that is in contact with the cutting edge strip. The driving component is drivenly connected to the annular steel belt to drive the annular steel belt to rotate. The driving component is also drivenly connected to the second cutting component.

[0008] According to some embodiments of the present invention, the driving assembly includes a driving wheel, at least one driven wheel, and a driver. The driving wheel is rotatably mounted on the partition and is driven by the annular steel belt. The driven wheel is rotatably mounted on the partition and is driven by the annular steel belt. The driver is driven by the driving wheel.

[0009] According to some embodiments of this utility model, the second cutting assembly includes a base, a slider, an elastic element, a connecting rod, a cutting blade, and a rotating block. The base is provided with a sliding groove and two opposing limiting parts. The slider is slidably limited within the sliding groove. The elastic element is disposed between the sliding groove and the slider and is in a compressed state. One end of the connecting rod is rotatably connected to the end of the slider away from the elastic element. The cutting blade is rotatably disposed on the base and close to the annular steel strip. The cutting blade is rotatably connected to the other end of the connecting rod and is limited between the two limiting parts. The rotating block is driven by the driver and is provided with a top block that cooperates with the cutting blade. When the driver drives the rotating block to rotate half a turn, the top block pushes the cutting blade upward, causing the cutting blade to tilt towards its rotation center.

[0010] According to some embodiments of the present invention, the cutting knife includes a knife holder and a blade. The middle part of the knife holder is rotatably connected to the connecting rod. A straight arm is formed on both sides of the rotation center of the knife holder. The knife holder is limited between the two limiting parts. A stop block is provided on the straight arm. The blade is disposed at the end of one of the straight arms.

[0011] According to some embodiments of the present invention, the top block has an arc-shaped edge.

[0012] According to some embodiments of the present invention, the second adsorption component includes a vacuum pump and a vacuum pipe connected to the suction port of the vacuum pump. The first vacuum nozzle is provided at one end of the vacuum pipe away from the suction port. The fabric cutting edge strip device further includes a crushing device, which is connected in series in the vacuum pipe of the vacuum pump.

[0013] According to some embodiments of the present invention, a bag filter is provided between the crushing chamber of the crushing device and the vacuum pump.

[0014] According to some embodiments of the present invention, the first cutting assembly includes a telescopic cylinder, a first swing arm, a second swing arm, and a rotating cutter head.

The middle part of the second swing arm is rotatably mounted on the conveyor belt. The rotating cutter head is located at the end of the second swing arm away from the first swing arm.

[0015] According to an embodiment of the present invention, a fabric edge-cutting device has at least the following advantages: when the bonding part rotates, the cutting part can periodically press against and move away from the bonding part. When the cutting part periodically presses against the bonding part, the edge strips adsorbed on the bonding part are cut, and at the same time, a portion of the bonding part stops generating negative pressure. Thus, the negative pressure generated by the first vacuum nozzle pulls the edge strips away. When the cutting part moves away from the bonding part, the corresponding area of ​​the bonding part generates negative pressure again. By repeating the above operation, the edge strips can be automatically collected. The existing collection method has higher collection efficiency and does not require manual intervention or consideration of personnel safety. Attached Figure Description

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Reference Figures 1 to 4As shown, this utility model discloses a fabric edge-cutting device, including a conveyor belt 100, a first cutting component 200, a first adsorption component 300, a second cutting component 400, and a second adsorption component. A roller 110 of the conveyor belt 100 has a corner section with a first side 111 and a second side 112. In use, the conveyor belt 100 is used to transport fabric. The first cutting component 200 is located on the first side 111 and is used to cut the edge of the fabric to form a cut edge strip. The first adsorption component 300 is located on the second side 112 and has a rotating, cyclically rotating adhesive portion that generates negative pressure to adsorb the cut edge strip. The second cutting component 400 is located on the second side 112 and has a cutting portion. The second cutting component 400 is drive-connected to the first adsorption component 300. The second adsorption component is provided with a first vacuum nozzle 510 for adsorbing and pulling the cut edge strip on the side near the first adsorption component 300. In order to adjust the working state of the first vacuum nozzle 510, the first vacuum nozzle 510 can be opened and closed.

[0031] In this embodiment, when the bonding part rotates, the cutting part periodically presses against and moves away from the bonding part. When the cutting part periodically presses against the bonding part, the cutting edge strip adsorbed on the bonding part is cut, and at the same time, a part of the bonding part stops generating negative pressure. In this way, the negative pressure generated by the first vacuum nozzle 510 pulls the cutting edge strip, thereby sucking the cutting edge strip away. When the cutting part moves away from the bonding part, the area corresponding to the bonding part generates negative pressure again.

[0032] In some embodiments of this utility model, such as Figure 2 As shown, the first adsorption assembly 300 includes a partition 310, an annular steel belt 320, multiple second vacuum nozzles 330, and a drive assembly. The annular steel belt 320 is rotatably mounted on the partition 310, and the annular steel belt 320 and the partition 310 are sealed together to form a relatively sealed air cavity 350. The multiple second vacuum nozzles 330 are all located within the air cavity 350, and each second vacuum nozzle 330 has an air hole 331 on the side of the annular steel belt 320 that is in contact with the cutting edge. The second vacuum nozzles 330 are used to connect to external vacuum equipment, such as a vacuum pump. The drive assembly is driven by the annular steel belt 320. When the drive assembly is in operation, it drives the annular steel belt 320 to rotate. The drive assembly is also driven by the second cutting assembly 400. Thus, when the annular steel belt 320 rotates, the drive assembly simultaneously drives the cutting part to periodically press against and move away from the side of the annular steel belt 320 that is in contact with the cutting edge.

[0033] It should be noted that the radiation area of ​​the adsorption effect of each second vacuum nozzle 330 corresponds to a local area of ​​the side of the annular steel belt 320 that is in contact with the cutting edge strip. This can control the partial area of ​​the contact part to stop generating negative pressure, ensuring that when cutting the cutting edge strip, the cutting edge strip that continues to be conveyed on the conveyor belt 100 can be adsorbed by the area of ​​the contact part that has not stopped generating negative pressure, while the cutting edge strip in the area of ​​the contact part that has stopped generating negative pressure loses its adsorption effect and is thus successfully sucked away by the negative pressure generated by the first vacuum nozzle 510.

[0034] In some embodiments of this utility model, such as Figure 1 As shown, the drive assembly includes a drive wheel 341, at least one driven wheel 342, and a driver. The drive wheel 341 is rotatably mounted on the partition 310 and is driven by the annular steel belt 320. The driven wheel 342 is rotatably mounted on the partition 310 and is driven by the annular steel belt 320. The driver is driven by the drive wheel 341. Optionally, the driver can be a rotary cylinder, a rotary motor, or other power device.

[0035] In this embodiment, when the driver is in working condition, the driver drives the drive wheel 341 to rotate, and the rotation of the drive wheel 341 drives the annular steel belt 320 to rotate.

[0036] In some embodiments of this utility model, such as Figure 3 As shown, the second cutting assembly 400 includes a base 410, a slider 420, an elastic element 430, a connecting rod 440, a cutting blade 450, and a rotating block 460.

[0037] Specifically, the base 410 is provided with a slide groove 411, and the base 410 is provided with two opposing limiting parts 412. The slider 420 is slidably disposed in the slide groove 411, and the slide groove 411 simultaneously limits the slider 420, preventing the slider 420 from disengaging from the slide groove 411 during movement. Optionally, an end cap can be provided at the edge of the slide groove 411, with a through hole on the end cap, making the slider 420 stepped. The larger end of the slider 420 matches the size of the slide groove 411, and the smaller end of the slider 420 extends from the through hole to the outside of the slide groove 411. An elastic element 430 is disposed between the slide groove 411 and the slider 420, and the elastic element 430 is always in a compressed state. Optionally, the elastic element 430 can be a spring, a sheet spring, or other components. One end of the connecting rod 440 is rotatably connected to the end of the slider 420 away from the elastic element 430. The cutting blade 450 is rotatably mounted on the base 410 and close to the annular steel belt 320. When the cutting blade 450 rotates, its swing range is limited by the limiting part 412. The cutting blade 450 is rotatably connected to the other end of the connecting rod 440. The rotating block 460 is connected to the drive driver. The rotating block 460 is provided with a top block 461 that cooperates with the cutting blade 450.

[0038] In this embodiment, when the driver drives the rotating block 460 to rotate half a turn, the top block 461 pushes the cutting blade 450 upward, causing the cutting blade 450 to tilt towards one side of its rotation center. When the driver drives the rotating block 460 to continue rotating half a turn, the top block 461 pushes the cutting blade 450 upward, causing the cutting blade 450 to tilt towards the other side of its rotation center. It should be noted that the rotation speed of the rotating block 460 must match the transmission speed of the conveyor belt 100 to prevent the cutting blade 450 from scratching the surface of the transmitted fabric.

[0039] In some embodiments of this utility model, such as Figure 3 As shown, the limiting part 412 is a stop bar. The cutting blade 450 includes a blade holder 451 and a blade 452. The middle part of the blade holder 451 is rotatably connected to the connecting rod 440. When the blade holder 451 rotates, its swing range is limited by the stop bar. A straight arm 453 is formed on both sides of the rotation center of the blade holder 451. A stop block 454 is provided on each of the two straight arms 453. The blade 452 is located at the end of one of the straight arms 453. When the cutting blade 450 tilts to one side of its rotation center, the blade 452 presses against the side of the annular steel strip 320 that is in contact with the cutting edge strip, thereby quickly cutting the cutting edge strip.

[0040] In some embodiments of this utility model, such as Figure 3 As shown, in order to prevent the top block 461 from being blocked by the stop block 454 and thus stop rotating, the top block 461 is provided with an arc-shaped edge 4611. By setting the arc-shaped edge 4611, the stop block 454 can be smoothly raised gradually along the extension path of the arc-shaped edge 4611.

[0041] In order to accurately control the negative pressure in certain areas of the bonding part, in some embodiments of this utility model, the driving stroke of the driver can be detected by a sensor. When the driver drives the annular steel belt 320 to rotate and move a preset stroke, the second vacuum nozzle 330 stops generating negative pressure, for example, by turning off the vacuum pump connected to the second vacuum nozzle 330.

[0042] In order to accurately control the negative pressure in certain areas of the bonding part, in some embodiments of this utility model, a sensor can be used to detect whether the cutting blade 450 is in contact with the surface of the annular steel strip 320. When the cutting blade 450 is detected to be in contact with the surface of the annular steel strip 320, the second vacuum nozzle 330 is stopped from generating negative pressure, for example, by turning off the vacuum pump connected to the second vacuum nozzle 330.

[0043] In some embodiments of this utility model, such as Figure 1As shown, the second adsorption assembly includes a vacuum pump (not shown in the figures) and a vacuum pipe 520 connected to the suction port of the vacuum pump. A first vacuum nozzle 510 is provided at one end of the vacuum pipe 520 away from the suction port of the vacuum pump. The fabric cutting edge strip device also includes (not shown in the figures), a crushing device connected in series in the vacuum pipe 520 of the vacuum pump.

[0044] In some embodiments of this invention, a bag filter (not shown in the drawings) is provided between the crushing chamber of the crushing device and the vacuum pump to prevent fabric scraps from being sucked into the vacuum pump.

[0045] In some embodiments of this utility model, such as Figure 4 As shown, the first cutting assembly 200 includes a telescopic cylinder 210, a first swing arm 220, a second swing arm 230, and a rotating cutter head 240. The cylinder body 211 of the telescopic cylinder 210 is rotatably mounted on the conveyor belt 100. One end of the first swing arm 220 is connected to the telescopic rod 212 of the telescopic cylinder 210. One end of the second swing arm 230 is rotatably connected to the end of the first swing arm 220 away from the telescopic rod 212. The middle part of the second swing arm 230 is rotatably mounted on the conveyor belt 100. The rotating cutter head 240 is located at the end of the second swing arm 230 away from the first swing arm 220.

[0046] In this embodiment, when the telescopic rod 212 of the telescopic cylinder 210 extends or retracts, the rotating cutter head 240 moves closer to and further away from the fabric on the conveyor belt 100 through the transmission of the first swing arm 220 and the second swing arm 230.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
