Description

Technical Field

[0001] This application relates to the field of textile technology, and in particular to a collar cutting device capable of both edge trimming and center trimming. Background Technology

[0002] In the textile industry, the collar strips of knitted garments are woven using flat knitting machines or circular knitting machines. The width of these knitted strips is often insufficient to meet the precision requirements of the product, so the collar edges need to be narrowed after knitting. Furthermore, traditional techniques consider the cost of knitting collars one strip at a time to be too high; therefore, they are typically knitted using two strips of equal length to reduce costs, and then cut in the center of the two strips after knitting. In other words, traditional techniques achieve product quality and production requirements by trimming the collar strips at the edges and centering the cut. However, this trimming and centering process requires manual operation by workers, one strip after another. After trimming, multiple strips are arranged neatly before being cut in the center on a cutting bed. This manual operation is inefficient, and the instability of manual operation also affects the dimensional accuracy of the collar strips, thus impacting the quality of the finished product. Utility Model Content

[0003] Therefore, it is necessary to provide a collar cutting device that can perform edge trimming and center cutting. The collar cutting device of this application that can perform edge trimming and center cutting can improve the degree of automation, realize edge trimming and center cutting of the knitted collar strip, improve the quality of the finished collar strip, reduce manual intervention, and reduce labor costs.

[0004] One embodiment of this application provides a collar cutting device capable of both edge trimming and center trimming.

[0005] A collar cutting device capable of edge trimming and center cutting includes a machine base and a feeding mechanism, an overlocking mechanism, a feeding mechanism, a limiting mechanism, and a cutting mechanism mounted on the machine base. The feeding mechanism is used to feed connecting collar strips one by one to the overlocking mechanism. The overlocking mechanism is used to overlock and trim the connecting collar strips. The feeding mechanism is located between the overlocking mechanism and the cutting mechanism. The feeding mechanism is used to feed the connected collar strips processed by the overlocking mechanism to the cutting mechanism. The limiting mechanism is used to restrict the processed connected collar strips to a predetermined position. The cutting mechanism is used to center-cut the connecting collar strips to obtain two separate collar strips.

[0006] In some embodiments, the feeding mechanism includes a feeding plate, a feeding drive component, and a feeding component. The feeding plate is movably connected to the machine base for placing stacked connecting strips. The feeding drive component is mounted on the machine base and connected to the feeding plate. The feeding drive component drives the feeding plate to move up and down until it is flush with the worktable surface of the machine base. The feeding component is movably connected to the machine base for conveying the connecting strips on the feeding plate one by one to the overlocking mechanism. After the first layer of connecting strips on the feeding plate is conveyed by the feeding component, the feeding drive component drives the feeding plate to rise to the height of one connecting strip thickness.

[0007] In some embodiments, the feeding component includes pneumatic fingers that are capable of feeding the connecting strips on the feeding plate one by one to the overlocking mechanism.

[0008] In some embodiments, the feeding mechanism further includes a feeding roller and a feeding drive component. The feeding roller is movably connected between the feeding component and the overlock mechanism. The feeding drive component is mounted on the machine base and connected to the feeding roller. The feeding drive component is used to drive the feeding roller to press down onto the connecting strip and drive the connecting strip into the overlock mechanism.

[0009] In some embodiments, the feeding mechanism includes a first feeding conveyor belt and a first feeding drive component, one end of the first feeding conveyor belt extending to the overlock mechanism and the other end extending to the cutting mechanism, and the first feeding drive component being connected to the first feeding conveyor belt for driving the first feeding conveyor belt to move.

[0010] In some embodiments, the first feeding conveyor belt is located above the worktable of the machine and has a gap with the worktable for the passage of the connecting strip, and the first feeding conveyor belt drives the connecting strip to move forward under the drive of the first feeding drive component.

[0011] In some embodiments, the feeding mechanism includes a second feeding conveyor belt and a second feeding drive component. The second feeding conveyor belt is mounted on the machine base and adjacent to the cutting mechanism. The second feeding drive component is connected to the second feeding conveyor belt to drive the second feeding conveyor belt to move. The second feeding conveyor belt receives the connecting strip processed by the overlocking mechanism and conveys the connecting strip to a predetermined position that conforms to the center cut.

[0012] In some embodiments, the limiting mechanism includes a limiting baffle located at the end of the second feeding conveyor belt in the conveying direction. The limiting baffle is used to restrict the end of the connecting strip. When the front end of the connecting strip abuts the limiting baffle, it indicates that the connecting strip has moved to a predetermined position that conforms to the center cut.

[0013] In some embodiments, the limiting mechanism further includes a trigger switch mounted on the surface of the limiting baffle facing the second feeding conveyor belt. When the front end of the connecting strip abuts against the limiting baffle and triggers the trigger switch, the cutting mechanism operates.

[0014] In some embodiments, the cutting mechanism includes a cutting push plate, a push plate driving component, a cutter, and a cutting driving component. The cutting push plate is movably connected to the machine base, and the push plate driving component is mounted on the machine base and connected to the cutting push plate. The push plate driving component is used to drive the cutting push plate to push the connecting strip located at a predetermined position into the cutting station.

[0015] The cutter is movably connected to the machine base, and the cutting drive component is installed on the machine base and connected to the cutter. The cutting drive component is used to drive the cutter to cut the connecting strip at the cutting station in the center to obtain two separated strips.

[0016] In some embodiments, the collar cutting device capable of edge trimming and center cutting further includes a receiving mechanism mounted on the machine base, the receiving mechanism being used to receive the two separated collar strips after center cutting.

[0017] In some embodiments, the receiving mechanism includes a receiving plate, a receiving drive component, a receiving basket, and a receiving release component. The receiving plate has multiple spaced racks on the side facing the predetermined position. The receiving plate is provided with a cutting station and can receive connecting strips from the predetermined position. The receiving drive component is mounted on the machine base and connected to the receiving plate. The receiving drive component can drive the receiving plate to move up and down and to move horizontally. The receiving basket is disposed below the receiving plate to receive two separated strips that have been cut in the center on the receiving plate. The receiving release component includes multiple spaced stops that can cross-engage with multiple racks on the receiving plate.

[0018] After the center cut is completed, the receiving drive component drives the receiving plate to descend to a predetermined height and disengage from the receiving release component in the height direction. The receiving drive component then drives the receiving plate to move laterally to the other side of the receiving release component. The receiving drive component then drives the receiving plate to return to its horizontal position. The collar strip on the receiving plate disengages from the receiving plate under the restriction of the receiving release component and is collected in the receiving basket. Finally, the receiving drive component drives the receiving plate to rise and return to its original position.

[0019] Alternatively, after the center cut is completed, the receiving drive component drives the receiving plate to move laterally into the receiving basket, the receiving detachment component descends to interlock with the receiving plate, and the receiving drive component drives the receiving plate to reset laterally so that the collar strip on the receiving plate is detached from the receiving plate under the restriction of the receiving detachment component and collected in the receiving basket.

[0020] The aforementioned collar cutting device, capable of edge trimming and center cutting, automatically performs edge trimming, center cutting, and other processes on the connecting collar strips by setting up a feeding mechanism, overlocking mechanism, feeding mechanism, limiting mechanism, and cutting mechanism that work together. The process requires virtually no manual intervention, has a high degree of automation, significantly saves labor, reduces labor costs, and improves production efficiency. Automated operation can also improve the quality of products in different batches and enhance product quality consistency. Attached Figure Description

[0035] This application provides a collar cutting device capable of edge trimming and center cutting to solve at least one of the following technical problems in the traditional technology of trimming and center cutting the woven collar strips: (1) It requires operators to operate by hand throughout the entire process, one strip after another. After trimming, multiple collar strips are arranged neatly before being cut in the center on a cutting bed, which requires a high level of manpower and is highly dependent on manual labor; (2) The efficiency of manual operation in the traditional technology is low, and the instability of manual operation has a certain impact on the dimensional accuracy of the collar strips, affecting the quality of the collar strip products. The collar cutting device capable of edge trimming and center cutting will be described below with reference to the accompanying drawings.

[0036] The collar cutting device 10 provided in this application embodiment, which can realize edge cutting and center cutting, is exemplified by [example provided]. Figure 1 As shown, Figure 1 This is a schematic diagram of the collar cutting device 10, which enables edge trimming and center cutting, provided in an embodiment of this application. The collar cutting device 10 of this application can be used to automatically trim and center collar strips, significantly reducing labor costs and improving the quality of finished collar strips.

[0037] To more clearly illustrate the structure of the collar cutting device 10 that can perform edge trimming and center trimming, the collar cutting device 10 that can perform edge trimming and center trimming will be described below with reference to the accompanying drawings.

[0038] For example, please refer to Figure 1 As shown, a collar cutting device 10 capable of edge trimming and center cutting includes a machine base 100 and a feeding mechanism 200, a sewing mechanism 300, a feeding mechanism 400, a limiting mechanism 500, and a cutting mechanism 600 mounted on the machine base 100. The feeding mechanism 200 feeds the connecting collar strips one by one to the sewing mechanism 300. The sewing mechanism 300 performs sewing and edge trimming on the connecting collar strips. The feeding mechanism 400 is positioned between the sewing mechanism 300 and the cutting mechanism 600. The feeding mechanism 400 feeds the connected collar strips processed by the sewing mechanism 300 to the cutting mechanism 600. The limiting mechanism 500 restricts the processed connecting collar strips to a predetermined position. The cutting mechanism 600 performs a center cut on the connecting collar strips to obtain two separate collar strips.

[0039] In some embodiments, the feeding mechanism 200 includes a feeding plate 201, a feeding drive component 202, and a feeding component 203. The feeding plate 201 is movably connected to the machine base 100 for placing stacked connecting strips. The feeding drive component 202 is mounted on the machine base 100 and connected to the feeding plate 201. The feeding drive component 202 drives the feeding plate 201 to move up and down until it is flush with the worktable surface 101 of the machine base 100. The feeding component 203 is movably connected to the machine base 100 for conveying the connecting strips on the feeding plate 201 one by one to the overlock sewing mechanism 300. After the first layer of connecting strips on the feeding plate 201 is conveyed by the feeding component 203, the feeding drive component 202 drives the feeding plate 201 to rise by the thickness of one connecting strip. In this application, the feeding plate 201 and the feeding drive component 202 are set to realize the feeding of the connecting strip in the vertical direction. After the first layer of connecting strip is fed, the feeding plate 201 can rise to a certain height under the drive of the feeding drive component 202, so that the connecting strip located in the second layer is sent to the first layer position for the next feeding.

[0040] Preferably, the feeding mechanism 200 further includes a height detection sensor. The height detection sensor is used to detect the height position of the feeding plate 201 or the height position of the first layer connecting strip on the feeding plate 201. When the height detection sensor does not detect the corresponding object, the feeding drive component 202 drives the feeding plate 201 to rise until the height detection sensor detects the corresponding object.

[0041] In some embodiments, the feeding component 203 includes pneumatic fingers. The pneumatic fingers are capable of feeding the connecting strips on the feed plate 201 one by one to the overlock sewing mechanism 300.

[0042] In some embodiments, the feeding mechanism 200 further includes a feeding roller 204 and a feeding drive component 205. The feeding roller 204 is movably connected between the feeding component 203 and the overlock sewing mechanism 300. The feeding drive component 205 is mounted on the machine base 100 and connected to the feeding roller 204. The feeding drive component 205 drives the feeding roller 204 down onto the connecting strip and drives the connecting strip into the overlock sewing mechanism 300. The feeding roller 204 is provided with a roller, and the feeding drive component 205 drives the feeding roller 204 down onto the first layer of connecting strip, driving the feeding roller 204 to move toward the overlock sewing mechanism 300. When the first end of the first layer of connecting strip moves to the overlock sewing mechanism 300, the feeding drive component 205 drives the feeding roller 204 to reset, ready for the next feeding.

[0043] In some embodiments, the feeding mechanism 400 includes a first feeding conveyor belt 401 and a first feeding drive component 402. One end of the first feeding conveyor belt 401 extends to the overlock mechanism 300 and the other end extends to the cutting mechanism 600. The first feeding drive component 402 is connected to the first feeding conveyor belt 401 to drive the first feeding conveyor belt 401 to move. In this embodiment, the first feeding conveyor belt 401 is used to move the connecting strip from the overlock mechanism 300 to the cutting mechanism 600, so that the overlocked and trimmed connecting strip enters the cutting mechanism 600.

[0044] In some embodiments, the first feeding conveyor belt 401 is located above the worktable 101 of the machine base 100 and has a gap with the worktable 101 for the passage of the connecting strip. The first feeding conveyor belt 401 drives the connecting strip forward under the drive of the first feeding drive unit 402.

[0045] In some embodiments, the feeding mechanism 400 includes a second feeding conveyor belt 403 and a second feeding drive component. The second feeding conveyor belt 403 is mounted on the machine base 100 and adjacent to the cutting mechanism 600. The second feeding drive component is connected to the second feeding conveyor belt 403 to drive the second feeding conveyor belt 403. The second feeding conveyor belt 403 receives the connecting strip processed by the overlock sewing mechanism 300 and conveys the connecting strip to a predetermined position that conforms to the center cut. In this embodiment, by setting the second feeding conveyor belt 403, the connecting strip is moved from the cutting mechanism 600 to the predetermined position that conforms to the center cut, so that the cutting push plate 601 of the cutting mechanism 600 pushes the connecting strip directly below the cutter 603. This application achieves automatic conveying of connecting strips through the first feeding conveyor belt 401 and the second feeding conveyor belt 403, saving the trouble of manual auxiliary conveying. The first feeding conveyor belt 401 and the second feeding conveyor belt 403 work together to move the connecting strips to the accurate position so as to make center cutting.

[0046] In some embodiments, the limiting mechanism 500 includes a limiting baffle 501. The limiting baffle 501 is located at the end of the second feeding conveyor belt 403 in the conveying direction. The limiting baffle 501 is used to restrict the end of the connecting strip; when the front end of the connecting strip abuts against the limiting baffle 501, it indicates that the connecting strip has moved to a predetermined position conforming to the center cut. See also... Figure 1 As shown, the limiting baffle 501 is located at the end of the conveying direction. When the connecting strip is conveyed by the second feeding conveyor belt 403 to abut the limiting baffle 501, it indicates that the connecting strip has moved into place in the conveying direction. At this time, the second feeding conveyor belt 403 notifies the conveying mechanism that the cutting push plate 601 of the cutting mechanism 600 can push the connecting strip to move directly below the cutter 603 of the cutting mechanism 600 in a direction perpendicular to the conveying direction. That is, at this time, the connecting part of the connecting strip at the center position is located directly below the cutter 603 of the cutting mechanism 600.

[0047] In some embodiments, the length of the limiting baffle 501 along the worktable surface 101 of the machine tool 100 is not less than the width of the second feeding conveyor belt 403. This arrangement ensures that the limiting baffle 501 can cover the second feeding conveyor belt 403 in the horizontal direction, and any point of the end of the connecting strip is within the limiting range of the limiting baffle 501. The width of the second feeding conveyor belt 403 mentioned above refers to the width of the second feeding conveyor belt 403 along the direction of the worktable surface 101, that is, the dimension perpendicular to the length direction of the second feeding conveyor belt 403.

[0048] In some embodiments, the limiting mechanism 500 also includes a trigger switch. The trigger switch is mounted on the surface of the limiting baffle 501 facing the second feeding conveyor belt 403. When the front end of the connecting strip abuts against the limiting baffle 501 and triggers the trigger switch, the second feeding conveyor belt 403 stops conveying, and then the cutting mechanism 600 actuates. For example, the cutting mechanism 600 pushes the connecting strip on the second feeding conveyor belt 403 along a direction perpendicular to the conveying direction directly below the cutter 603 for centered cutting.

[0049] In some embodiments, the cutting mechanism 600 includes a cutting pusher plate 601, a pusher plate driving component 602, a cutter 603, and a cutting drive component 604. The cutting pusher plate 601 is movably connected to the machine base 100. The pusher plate driving component 602 is mounted on the machine base 100 and connected to the cutting pusher plate 601. The pusher plate driving component 602 drives the cutting pusher plate 601 to push the connecting strip located at a predetermined position into the cutting station. The cutter 603 is movably connected to the machine base 100. The cutting drive component 604 is mounted on the machine base 100 and connected to the cutter 603. The cutting drive component 604 drives the cutter 603 to cut the connecting strip at the cutting station in the center, so as to obtain two separated strips. In this application, the connecting strip on the second feeding conveyor belt 403 is pushed directly below the cutter 603 by the cooperation of the cutting push plate 601 and the push plate driving component 602. That is, at this time, the connecting part of the connecting strip at the center position is directly below the cutter 603 of the cutting mechanism 600.

[0050] In some embodiments, the cutting pusher plate 601 and the pusher plate driving component 602 form a group. The number of cutting pusher plates 601 and pusher plate driving components 602 can be multiple groups. Each group is used to push the connecting strip so that the entire connecting strip moves directly below the cutter 603. That is, multiple cutting pusher plates 601 can push multiple positions of the connecting strip to ensure that the entire connecting strip can move.

[0051] In some embodiments, the collar cutting device 10, which enables edge trimming and center cutting, also includes a receiving mechanism 700 mounted on the machine base 100. The receiving mechanism 700 is used to receive the two separated collar strips after center cutting.

[0052] In some embodiments, the receiving mechanism 700 includes a receiving plate 701, a receiving drive component, a receiving basket 702, and a receiving release component 703. The receiving plate 701 has multiple spaced racks on one side facing a predetermined position. A cutting station is provided on the receiving plate 701. The receiving plate 701 is capable of receiving connecting strips from the predetermined position. The receiving drive component is mounted on the machine base 100 and connected to the receiving plate 701. The receiving drive component is capable of driving the receiving plate 701 to move vertically and horizontally. The receiving basket 702 is disposed below the receiving plate 701 to receive two separated strips that have been cut centered on the receiving plate 701. The receiving release component 703 includes multiple spaced-apart stops 7032. The multiple stops 7032 can engage with multiple racks on the receiving plate 701 in a cross-coupling manner. The receiving drive component is not shown in the drawings.

[0053] In some embodiments, the receiving and detaching component 703 includes a detaching plate 7031, a plurality of spaced-apart baffles 7032 connected to the detaching plate 7031, and a detaching drive component 7033. The detaching plate 7031 and the plurality of spaced-apart baffles 7032 are generally comb-shaped. The detaching drive component 7033 is mounted on the machine base 100 and connected to the detaching plate 7031. In this embodiment, the receiving mechanism 700 may perform the following: In the initial stage, the receiving plate 701 is flush with the second feeding conveyor belt 403. When the connecting strip on the second feeding conveyor belt 403 reaches a predetermined position, the push plate drive component 602 drives the cutting push plate 601 to push the connecting strip onto the flush receiving plate 701. The cutting drive component 604 drives the cutter 603 to cut the connecting strip at the cutting station in the center, resulting in two separated strips. After the center cut is completed, the receiving drive unit drives the receiving plate 701 to move laterally above the receiving basket 702. The disengagement drive unit 7033 drives the disengagement plate 7031 to descend until each stop bar 7032 inserts into the gap between adjacent racks on the receiving plate 701, completing the cross-coupling of the stop bars 7032 and the racks. When the stop bars 7032 and the racks move independently, they do not affect each other. The receiving drive unit drives the receiving plate 701 to move laterally to reset. Due to the blocking effect of the stop bars 7032, the collar strips on the receiving plate 701 will remain in place. When the receiving plate 701 is completely removed from above the receiving basket 702, the collar strips fall into the receiving basket 702 without the support of the receiving plate 701, completing the collection of the collar strips. Since the collar strips are collected one by one, the collar strips in the receiving basket 702 are stacked along the height direction, which facilitates neat collection and avoids the trouble of manually sorting the collar strips again laterally.

[0054] It is not difficult to connect them. The cooperation between the receiving plate 701, the receiving drive component, the receiving basket 702, and the receiving detachment component 703 can also be in other forms, as long as the collar strip can be detached from the receiving plate 701.

[0055] For example, in some embodiments, after the center cut is completed, the take-up drive component drives the take-up plate 701 to descend to a predetermined height and disengage it from the take-up release component 703 in the height direction. The take-up drive component drives the take-up plate 701 to move laterally to the other side of the take-up release component 703. The take-up drive component drives the take-up plate 701 to return to its lateral position, and the collar strip on the take-up plate 701 disengages from the take-up plate 701 under the constraint of the take-up release component 703 and is collected in the take-up basket 702. The take-up drive component drives the take-up plate 701 to rise and return to its original position.

[0056] For example, in some embodiments, after the center cut is completed, the receiving drive component drives the receiving plate 701 to move laterally into the receiving basket 702. The receiving detachment component 703 descends to interlock with the receiving plate 701. The receiving drive component drives the receiving plate 701 to return to its lateral position so that the collar strip on the receiving plate 701 is detached from the receiving plate 701 under the constraint of the receiving detachment component 703 and collected in the receiving basket 702.

[0057] It is easy to understand that the receiving mechanism 700 in this application can also receive materials in other ways.
