Technical Field

[0001] This utility model relates to the field of placket processing technology, and in particular to a feeding mechanism for placket sewing. Background Technology

[0002] Originating in the 19th century, the polo shirt has evolved into a classic garment that people enjoy wearing and is widely seen on various occasions. In the production process of the polo shirt, attaching the placket is an important step in its sewing process.

[0003] Currently, most plackets on the market are sewn using template machines. This requires first placing the placket fabric on a large piece of fabric and sewing a V-shaped topstitch. Then, by folding the placket fabric left and right, a hidden stitch is sewn on each side of the V-shaped topstitch to ensure the quality of the placket sewing. However, in the above placket sewing process, the feeding, sewing, and unloading of the placket all need to be completed on the sewing processing table, which seriously affects the efficiency of placket sewing. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a feeding mechanism for placket sewing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding mechanism for placket sewing includes: a feeding table, on which a template is placed, and on which clamps for holding and fixing the two sides of the placket fabric are provided, and on which a push rod capable of driving the clamps to open is provided.

[0007] Preferably, the clamp includes a movable seat, and the push rod is slidably disposed on the unloading platform and can be driven to press against the movable seat to open the clamp.

[0008] Preferably, the push rod is provided with a pressing slope, which can abut against the movable seat and be driven to compress the movable seat.

[0009] Preferably, the push rod is laterally slidably mounted on the feeding platform via a sliding block, and the push rod is driven to slide laterally and can press against the moving seat.

[0010] Preferably, the feeding platform is provided with a push rod cylinder, and a connecting rod connected to the sliding block is hinged to the driving end of the push rod cylinder.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit 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.

[0029] Example 1:

[0030] refer to Figures 5-12 As shown, this embodiment discloses a feeding mechanism for placket sewing, including: a feeding platform 6, which is used to place the template 3 and is located on one side of the processing table 1. The template 3 is provided with clamps for clamping and fixing the two sides of the placket fabric. The clamps include clamping pieces 321 and folding pieces 324. It can also be understood that the feeding platform 6 is provided with a push rod 61 that can drive the clamping pieces 321 away from the folding pieces 324. That is, the feeding platform 6 is provided with a push rod 61 that can drive the clamps to open. The clamps are opened by the push rod 61 so that the template 3 on the feeding platform 6 can be picked up and fed.

[0031] That is, by setting up a feeding platform 6 independently on one side of the processing table 1, the large fabric and the placket fabric can be picked up and fed on the feeding platform 6 at the same time when they are sewn on the processing table 1, so as to avoid the processing table 1 being in standby mode during the picking up and feeding process, thereby greatly improving the efficiency of placket sewing.

[0032] The clamp also includes a movable seat 323. The push rod 61 is slidably disposed on the feeding platform 6 and can be driven to press against the movable seat 323 to open the clamp. The push rod 61 moves back and forth along the longitudinally distributed slide rail. A pressing inclined surface 611 is provided on the push rod 61. The pressing inclined surface 611 can approach and squeeze the movable seat 323 to move.

[0033] Specifically, the feeding platform 6 is equipped with a push rod cylinder 62 that drives the push rod 61 to move back and forth. The push rod cylinder 62 can drive the push rod 61 to press against the movable seat 323, that is, the pressing inclined surface 611 can abut against the movable seat 323 and be driven to squeeze the movable seat 323, so that the movable seat 323 can move and open the clamps on both sides.

[0034] To increase the stroke of the push rod 61 in driving the clamp to open, the push rod 61 can also be slidably arranged laterally. Specifically, the push rod 61 is slidably arranged laterally on the feeding table 6 via the sliding block 64, and the sliding block 64 is slidably connected to the slide rail, so that the push rod 61 can be laterally displaced through the sliding block 64 and the slide rail.

[0035] The feeding platform 6 is equipped with a push rod cylinder 62. The drive end of the push rod cylinder 62 is hinged to a connecting rod 63 connected to the sliding block 64. When the drive end of the push rod cylinder 62 retracts, the connecting rod 63 drives the sliding block 64 and the push rod 61 to slide towards the middle, so that the connecting rod 63 drives the sliding block 64 to slide laterally and drives the push rod 61 to press against the moving seat 323. That is, the push rod 61 is driven to slide laterally and can press against the moving seat 323, so that the clamps on both sides can be opened to a greater extent.

[0036] A positioning plate 39 is fixed on the template 3, and a positioning groove 391 is provided on the positioning plate 39. The feeding table 6 is provided with a card plate 65 that can be locked into the positioning groove 391. The template 3 is quickly positioned and placed by the card plate 65 being locked into the positioning groove 391.

[0037] This embodiment discloses another placket sewing device, including a processing table 1. The processing table 1 is provided with a sewing machine head 11, a template movement device 13, and a cutting device 12. The cutting device 12 is located on one side of the sewing machine head 11. The cutting device 12 can be a laser cutting device or a cold knife cutting device, used to cut the main fabric and the placket fabric.

[0038] The template 3 has a base plate 31 and a cover plate 32 for placing the large fabric and the placket fabric respectively. The large fabric is placed on the base plate 31, and the cover plate 32 is hinged to the base plate 31. The large fabric on the base plate 31 is pressed and positioned by flipping the cover plate 32.

[0039] The base plate 31 and cover plate 32 are provided with sewing grooves 33, through which the sewing machine head 11 can sew a V-shaped topstitch on the main fabric and the placket fabric. Both sides of the sewing groove 33 are provided with clamps that can hold the sides of the placket fabric. The clamps extend along the length of the sewing groove 33, and each clamp can be moved from one side of the sewing groove 33 to the other side to hold the left and right sides of the folded placket fabric.

[0040] In this embodiment, the clamp includes a clamping piece 321 and a folding piece 324. It can be understood that the clamping piece 321 and the folding piece 324 are provided on both sides of the sewing groove 33. The clamping piece 321 can be driven to move relative to the folding piece 324 and clamp the side of the placket fabric. The folding piece 324 can be driven to fold the side of the placket fabric. That is, the folding piece 324 can be driven to slide and drive the clamping piece 321 to move to the other side of the sewing groove 33 to fold the side of the placket fabric.

[0041] By placing a large piece of fabric on the base plate 31 and pressing it together with the cover plate 32, and then placing the placket fabric on the cover plate 32 and clamping and fixing the two sides of the placket fabric with the cooperation of the clamping pieces 321 and folding pieces 324 on both sides, the placket fabric is positioned and fixed, preventing it from shifting during the sewing process. This ensures the stability of the placket fabric during the folding process and improves the quality and effect of the subsequent sewing of the placket fabric. Moreover, this embodiment has a compact structure, is simple to operate, and has a low cost. At the same time, no manual intervention is required during the sewing process, and its degree of automation is high, making it suitable for widespread application.

[0042] The clamping piece 321 and the folding piece 324 are respectively fixed on the slider 1 322 and the slider 2 325. The cover plate 32 is provided with a slide rail that is slidably connected to the slider 1 322 and the slider 2 325. The clamping piece 321 and the folding piece 324 slide laterally on the slide rail through the slider 1 322 and the slider 2 325. A movable seat 323 is fixedly installed on the clamping piece 321. The movable seat 323 is fixed on the slider 1 322. When driven, the movable seat 323 can move the clamping piece 321 away from the folding piece 324 so that the placket fabric can be removed from between the clamping piece 321 and the folding piece 324.

[0043] The template 3 is connected to the template motion device 13 and can be driven to move horizontally on the processing table 1. Specifically, the processing table 1 is provided with a locking device 2 that is detachably connected to the template motion device 13. The locking device 2 includes a locking cylinder 22 that is detachably connected to the template motion device 13. The locking device 2 is detachably connected to the template motion device 13 through the locking cylinder 22.

[0044] The locking device 2 also includes an insert plate 211 that can be inserted into the positioning groove 391 of the positioning plate 39, and a clamping plate 24 that is driven to move and snapped into the fixing groove 392 of the positioning plate 39. The insert plate 211 is inserted into the positioning groove 391 to quickly and initially position the template 3 on the locking device 2, and the clamping plates 24 on both sides are driven to snap and fix the template 3 into the fixing grooves 392 on both sides of the positioning plate 39, so as to detachably lock and fix the template 3 to the locking device 2. The template 3 is detachably connected to the template movement device 13 through the locking device 2.

[0045] Specifically, the locking device 2 also includes a mounting plate 21 for fixing the insert plate 211 and a sliding plate 23 that is lifted and lowered on the mounting plate 21. A lifting cylinder 231 is installed on the mounting plate 21. The driving end of the lifting cylinder 231 is connected to the sliding plate 23 and can drive the sliding plate 23 to move up and down so as to drive the clamping plate 24 on the sliding plate 23 to move up and down together.

[0046] The sliding plate 23 is equipped with a clamping cylinder 241 for driving the clamping plate 24 to slide laterally. The clamping plate 24 is laterally slidably disposed on the sliding plate 23 and can be driven to engage in the fixing grooves 392 on both sides of the positioning plate 39, so as to achieve a reliable connection of the template 3 by engaging the clamping plate 24 in the fixing grooves 392.

[0047] When it is necessary to separate the locking device 2 from the template 3, the lifting cylinder 231 drives the clamping plate 24 upward away from the template 3 through the sliding plate 23, and avoids the sliding plate 23 from moving left and right to separate from the template 3 and dragging the template 3, and facilitates the quick disassembly, replacement and installation of the template 3.

[0048] Meanwhile, in the embodiment, both the clamping cylinder 241 and the folding cylinder 5 are mounted on the slide plate 23, and the clamping cylinder 4 is not used to open the clamps on the template 3, which greatly reduces the weight of the template 3 and makes it easier to manually move and transfer the template 3.

[0049] This embodiment also discloses a sewing method for a placket sewing device, including:

[0050] a. Place the large fabric and placket fabric to be sewn on template 3 of feeding platform 6;

[0051] b. After the large fabric and placket fabric on the template 3 of the processing table 1 are sewn, the template 3 on the processing table 1 is removed and the template 3 on the material feeding table 6 is placed on the worktable 1 for sewing.

[0052] c. Remove the large fabric and placket fabric that have been sewn and processed from the feeding table 6, and put the large fabric and placket fabric to be sewn and processed back on.

[0053] Example 2:

[0054] refer to Figures 1-4 As shown, this embodiment also discloses a placket sewing device. The difference between this embodiment and embodiment 1 is that in this embodiment, the template 3 is provided with a locking device 2 that is detachably connected to the template machine. The locking device 2 is fixedly installed on the template 3. The locking device 2 includes a locking cylinder 22 that can be detachably connected to the template movement device 13. The template movement device 13 is provided with a pin that can be inserted into the drive end of the locking cylinder 22. Thus, the template 3 can clamp and fix the pin through the drive end of the locking cylinder 22 to realize the quick insertion and removal of the template 3 and the template movement device 13.

[0055] Once the template motion device 13 is fixed to the template 3, the template motion device 13 can drive the template 3 to move in the XY direction on the processing table 1.

[0056] The cover plate 32 is equipped with a connecting seat 371 that can be driven to swing open and close. The base plate 31 is rotatably mounted with a cover plate cylinder 37. The driving end of the cover plate cylinder 37 is hinged to the connecting seat 371 so that the connecting seat 371 is driven by the cover plate cylinder 37 to swing open the cover plate 32 so that a large cloth can be placed on the base plate 31.

[0057] Furthermore, the cover plate 32 is equipped with a handle 38 that can drive it to swing open and close relative to the base plate 31. The cover plate 32 can be manually swung open and closed via the handle 38 to facilitate equipment debugging and use.

[0058] A clamping cylinder 4 is installed on the template 3. The driving end of the clamping cylinder 4 can abut against the movable seat 323 and drive the clamping piece 321 away from the folding piece 324. Thus, when the driving end of the clamping cylinder 4 abuts against the movable seat 323, the clamping piece 321 can slide away from the folding piece 324.

[0059] Furthermore, the template 3 is provided with a tension spring 34 connected to the clamping piece 321. The clamping piece 321 approaches and abuts against the folding piece 324 under the action of the tension spring 34. Thus, when the clamping piece cylinder 4 is not driving to abut against the moving seat 323, the clamping piece 321 can slide close to the folding piece 324 under the pulling force of the tension spring 34, so that the clamping piece 321 and the folding piece 324 can clamp and fix the placket fabric relatively stably and reliably.

[0060] Furthermore, by connecting a tension spring 34 to the clamping piece 321, the clamping piece 321 is subjected to the action of the tension spring 34 and cooperates with the folding piece 324 to continuously and stably clamp and fix the side of the placket fabric. When the clamping piece 321 moves away from the folding piece 324, it can be conveniently placed or removed from the placket fabric. When the folding piece 324 moves away from the action of the tension spring 34 through the clamping piece 321, it can drive the clamping piece 321 to fold and move, thereby realizing the folding action of the placket fabric. Under the action of the tension spring 34, the clamping piece 321 and the folding piece 324 can be automatically reset. Therefore, this embodiment has the advantages of convenient use and stable clamping.

[0061] A push plate 326 is fixedly installed on the folding piece 324. The push plate 326 is fixed on the slider 325. The two sides of the push plate 326 are provided with an outer limiting plate 35 and an inner limiting plate 36 for abutting and limiting the displacement of the folding piece 324. The left and right displacement stroke of the folding piece 324 is limited by the outer limiting plate 35 and the inner limiting plate 36. The push plate 326 can drive the folding piece 324 and the clamping piece 321 to move.

[0062] The template 3 is equipped with a folding cylinder 5. The driving end of the folding cylinder 5 can abut against the push plate 326 and drive the folding piece 324 to move. For example, when the left folding piece 324 is driven to the right position, the folding piece 324 abuts against the first slider 322 through the second slider 325 to drive the clamping piece 321 to move to the right. That is, the folding piece 324 overcomes the tension of the tension spring 34 and folds the left side of the placket fabric to the right, thereby realizing the folding action on both sides of the placket fabric so that the sewing machine head 11 can sew the hidden lines on the left and right sides.

[0063] Furthermore, the clamping piece 321 and the folding piece 324 are respectively provided with locking plates 327 that can abut and engage with each other. The locking plates 327 on the clamping piece 321 and the locking plates 327 on the folding piece 324 are staggered. When the clamping piece 321 and the folding piece 324 abut against the side of the placket fabric, the two staggered locking plates 327 can engage with each other to ensure the stability of the clamping between the clamping piece 321 and the folding piece 324.

[0064] Furthermore, limit baffles 328 are respectively installed vertically and vertically on the two sets of clamping pieces 321 and folding pieces 324 distributed on both sides (see reference). Figure 6 As shown in the figure, it can also be understood that the two clamps distributed on both sides are respectively installed with limit baffles 328 in an alternating manner, the two clamps on the left and right sides can be distributed in an alternating manner, and by setting the limit baffles 328 on the clamps, the clamping piece 321 and the folding piece 324 are prevented from being misaligned during the folding of the side of the placket fabric.

[0065] This embodiment also discloses a sewing method for a placket sewing device, including:

[0066] S1. Open the cover plate 32, place the large cloth on the base plate 31, and then press the large cloth together through the cover plate 32;

[0067] S2. The two sides of the placket fabric are clamped and fixed by clips 321 and folding tabs 324;

[0068] S3, Move template 3 to below sewing machine head 11 and sew a V-shaped topstitch;

[0069] S4. Move the side of the placket fabric horizontally using clip 321 and folding clip 324, and sew the hidden stitches on the left and right sides.

[0070] S5. The template 3 is moved to the bottom of the cutting device 12 and cuts the placket fabric and the main fabric along the center line to complete the sewing process.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
