[0032] Example 1

[0033] like Figure 1 and 2 As shown, a multi-strip sewing machine includes a sewing device 100 and a tape-making device 200 arranged side by side. The tape-making device 200 includes a tape-winding module 210, a tape-feeding module 220, a tape-cutting module 230, and a transfer module 240 arranged sequentially.

[0034] The tape winding module 210 includes a plurality of tape winding reels 211 arranged in parallel;

[0035] The tape feeding module 220 includes a plurality of tape feeding mechanisms 221 arranged in parallel, and one tape feeding mechanism 221 corresponds to one tape reel 211;

[0036] The tape cutting module 230 includes a plurality of tape cutting mechanisms 231 arranged in parallel, and one tape cutting mechanism 231 corresponds to one tape feeding mechanism 221;

[0037] The transfer module 240 includes a first forward mechanism 242, a rotating mechanism 243, and a plurality of transfer clamps 241 arranged in parallel. Each transfer clamp 241 corresponds to a cutting mechanism 231. All transfer clamps 241 are mounted on the first forward mechanism 242, and the first forward mechanism 242 is mounted on the rotating mechanism 243. When the rotating mechanism 243 rotates all transfer clamps 241 simultaneously toward the cutting module 230, the first forward mechanism 242 can simultaneously drive all transfer clamps 241 to translate relative to the cutting module 230. When the rotating mechanism 243 rotates all transfer clamps 241 simultaneously toward the sewing device 100, the first forward mechanism 242 can simultaneously drive all transfer clamps 241 to translate relative to the sewing device 100.

[0038] The multi-strip sewing equipment of this utility model simultaneously produces multiple strips by simultaneously setting multiple tape reels 211, multiple tape feeding mechanisms 221 and multiple tape cutting mechanisms 231 in the tape making device 200. Through the cooperation of the first forward mechanism 242 and the rotating mechanism 243, all transfer clamps 241 are controlled to transfer all strips from the tape cutting module 230 to the sewing device 100, and the sewing device 100 sews all strips onto the fabric, thereby improving sewing efficiency and shortening sewing time.

[0039] In operation, the operator first loads the corresponding raw material strips onto each reel 211, then extracts each raw material strip from its corresponding reel 211 and feeds it into its corresponding feeding mechanism 221; then, the multi-strip sewing equipment is started. After startup, the rotating mechanism 243 simultaneously rotates all the transfer clamps 241 toward the cutting module 230, aligning each transfer clamp 241 with its corresponding cutting mechanism 231. Simultaneously, the first forward mechanism 242 moves all the transfer clamps 241 closer to the cutting module 230, allowing each transfer clamp 241 to extend into its corresponding cutting mechanism 231. Then, each feeding mechanism 221 feeds the corresponding raw material strip into its corresponding cutting mechanism 231. The feeding length of each feeding mechanism 221 can be set individually, and each transfer clamp 241 clamps the corresponding raw material strip. Next, each cutting mechanism 231 cuts the corresponding raw material strip to form multiple strips. Then, the first forward mechanism 242 drives... All transfer clips 241 are moved away from the cutting module 230 so that each transfer clip 241 extends out of the corresponding cutting mechanism 231. The rotating mechanism 243 simultaneously rotates all transfer clips 241 toward the sewing device 100. The first forward mechanism 242 drives all transfer clips 241 to move closer to the sewing device 100 so that each transfer clip 241 extends into the sewing device 100. Each transfer clip 241 releases its corresponding strip. The first forward mechanism 242 drives all transfer clips 241 to move away from the sewing device 101 so that each transfer clip 241 extends out of the sewing device 100. Finally, the sewing device 100 sews all the strips onto the fabric.

[0040] In this embodiment, the sewing device 100 and the tape-making device 200 are arranged side by side along a first direction, and the tape winding module 210, tape feeding module 220, tape cutting module 230, and transfer module 240 are arranged sequentially along a second direction. In this case, the rotation angle of the rotating mechanism 243 is less than 180°. Ideally, the first direction is perpendicular to the second direction, in which case the rotation angle of the rotating mechanism 243 is equal to 90°.

[0041] In some examples, the parallel direction between the sewing device 100 and the tape-making device 200 is parallel to the arrangement direction between the tape winding module 210, the tape feeding module 220, the tape cutting module 230 and the transfer module 240, in which case the rotation angle of the rotating mechanism 243 is equal to 180°.

[0042] like Figure 3As shown, the belt feeding module 220 includes a belt feeding base plate 222, which has a pulley groove 223. Each belt feeding mechanism 221 includes a first limiting block 2211, a second limiting block 2212, a belt feeding wheel assembly 2213, and a belt pressing wheel assembly 2214. The first limiting block 2211 and the second limiting block 2212 are arranged opposite each other on the belt feeding base plate 222 in a direction perpendicular to the belt feeding direction to define a belt feeding groove for the corresponding raw material belt on the belt feeding base plate 222. The belt feeding wheel assembly 2213 is located on the belt feeding base plate 222. Below, there are a feed roller 2213a and a feed driver 2213b. The feed driver 2213b drives the feed roller 2213a to rotate. The feed roller 2213a is disposed in the pulley groove 223. The pressure roller assembly 2214 is located above the feed base plate 222 and includes a pressure roller 2214a and a pressure driver 2214b. The pressure driver 2214b drives the pressure roller 2214a to move up and down. The feed roller 2213a and the pressure roller 2214a are arranged opposite to each other.

[0043] In this embodiment, the belt feeding driver 2213b is a drive motor. The operator can adjust the belt feeding length of each belt feeding mechanism 221 by setting the number of rotations of each drive motor during belt feeding. The belt pressing driver 2214b is a compression spring, which uses the elastic force of the compression spring to push the belt pressing wheel 2214a against the belt feeding wheel 2213a, and provides a certain elastic buffer to prevent damage to the raw material belt.

[0044] like Figure 2 The belt feeding module 220 further includes a first adjustment mechanism 224. The first adjustment mechanism 224 drives the first limiting block 2211 and the second limiting block 2212 of all belt feeding mechanisms 221 to move relative to each other, so as to adjust the interval distance between the first limiting block 2211 and the second limiting block 2212, thereby adjusting the width of the belt feeding groove of all belt feeding mechanisms 221 to adapt to raw material belts of different widths.

[0045] like Figure 3 As shown, the first adjustment mechanism 224 includes an adjustment knob 2241, a plurality of first threaded screws 2242, and a plurality of first couplings 2243. Each first threaded screw 2242 corresponds to a belt feeding mechanism 221. The two ends of each first threaded screw 2242 are respectively threadedly connected to the corresponding first limiting block 2211 and second limiting block 2212, and the threading directions are opposite. Adjacent first threaded screws 2242 are connected to each other through corresponding first couplings 2243. The adjustment knob 2241 is connected to one of the first threaded screws 2242.

[0046] By manually rotating the adjustment knob 2241, the operator can simultaneously adjust the width of the feeding groove of each feeding mechanism 221 through the power transmission of the first threaded screw 2242 and the first coupling 2243.

[0047] In this embodiment, each first limiting block 2211 includes a first front limiting portion 2211(a) and a first rear limiting portion 2211(b) separately disposed on the front and rear sides of the pressure roller 2214a along the belt feeding direction, and each second limiting block 2212 includes a second front limiting portion 2212a and a second rear limiting portion 2212b separately disposed on the front and rear sides of the pressure roller 2214a along the belt feeding direction; the first front limiting portion 2211(a) and the second front limiting portion 2212b of the same belt feeding mechanism 221 212a is threadedly connected to a first threaded screw 2242, and the first rear limiting part 2211(b) and the second rear limiting part 2212b of the same belt feeding mechanism 221 are threadedly connected to another first threaded screw 2242; among all belt feeding mechanisms 221, one of the first threaded screws 2242 located in front of the pressure roller 2214a is connected to one of the first threaded screws 2242 located behind the pressure roller 2214a through a transmission assembly 2244.

[0048] In this embodiment, the transmission component 2244 is composed of a transmission wheel and a transmission belt, which is a common transmission structure in the art and will not be described in detail here.

[0049] like Figure 4 As shown, each tape cutting mechanism 231 includes a third limiting block 2311, a fourth limiting block 2312, and a cutter assembly 2313. The third limiting block 2311 and the fourth limiting block 2312 are arranged opposite each other in the direction perpendicular to the tape feeding direction to define the tape clamping groove of the corresponding transfer clamp 241. The cutter assembly 2313 is located between the tape clamping groove and the corresponding tape feeding mechanism 221. When all transfer clamps 241 move closer to the tape cutting module 230, each transfer clamp 241 extends into the corresponding tape clamping groove.

[0050] The cutting module 230 also includes a second adjustment mechanism 2314. The second adjustment mechanism 2314 connects and drives the third limiting block 2311 and the fourth limiting block 2312 of all cutting mechanisms 231 to move relative to each other, so as to adjust the interval distance between the third limiting block 2311 and the fourth limiting block 2312, thereby adjusting the width of the clamping groove of all cutting mechanisms 231 to adapt to raw material strips of different widths.

[0051] The second adjustment mechanism 232 includes a first adjustment driver 2321, a plurality of second threaded screws 2322, and a plurality of second couplings 2323. Each second threaded screw 2322 corresponds to a cutting mechanism 231. The two ends of each second threaded screw 2322 are respectively threadedly connected to the corresponding third limiting block 2311 and fourth limiting block 2312, and the threading directions are opposite. Adjacent second threaded screws 2322 are connected to each other through corresponding second couplings 2323. The first adjustment driver 2321 is connected to one of the second threaded screws 2322.

[0052] In this embodiment, the first adjustment driver 2321 is a drive motor. By setting the number of rotations of the drive motor, the operator can transmit power through the second threaded screw 2322 and the second coupling 2323, and simultaneously adjust the width of the clamping groove of each tape cutting mechanism 231.

[0053] Each cutting blade assembly 2313 includes a rotating blade holder 2313a, a mechanical blade head 2313b, a rotating driver 2313c, and a lifting driver 2313d. The rotating blade holder 2313a has a tape inlet 2313e that aligns with the corresponding tape clamping groove and tape feeding mechanism 221. The mechanical blade head 2313b and the lifting driver 2313d are mounted on the rotating blade holder 2313a, and the lifting driver 2313d drives the mechanical blade head 2313b to move up and down relative to the tape inlet 2313e. The rotating driver 2313c drives the rotating blade holder 2313a to rotate around the lifting shaft.

[0054] Each feeding mechanism 221 feeds the raw material strip into the corresponding cutting mechanism 231, and through the inlet 2313e of the corresponding cutter assembly 2313, it enters the clamping groove between the third limiting block 2311 and the fourth limiting block 2312; when the lifting driver 2313d drives the mechanical cutter head 2313b to descend, the mechanical cutter head 2313b cuts the corresponding raw material strip from the inlet 2313e.

[0055] The rotary driver 2313c drives the rotary cutter holder 2313a to rotate around the lifting shaft, adjusting the effective width of the tape inlet 2313e to accommodate raw material tapes of different widths. The effective width refers to the projection size of the tape inlet 2313e along the tape feeding direction onto the feeding groove of the corresponding tape feeding mechanism 221. When the rotary cutter holder 2313a rotates around the lifting shaft to different angles, the projection size of the tape inlet 2313e will also change accordingly.

[0056] like Figure 5As shown, the transfer module 240 also includes a third adjustment mechanism 244, which drives all the transfer clips 241 to move relative to each other to adjust the spacing between all the transfer clips 241 to adapt to the sewing spacing of all the strips on the fabric.

[0057] After the first forward mechanism 242 simultaneously moves all the transfer clamps 241 away from the cutting module 230, so that all the transfer clamps 241 remove all the tape strips from the cutting module 230, the third adjustment mechanism 244 then moves all the transfer clamps 241 relative to each other according to the sewing spacing of all the tape strips on the fabric, so as to adjust the spacing between all the transfer clamps 241. Before the first forward mechanism 242 simultaneously moves all the transfer clamps 241 closer to the cutting module 230, so that all the transfer clamps 241 extend into the cutting module 230, the third adjustment mechanism 244 first moves all the transfer clamps 241 relative to each other according to the spacing between all the cutting modules 231, so as to adjust the spacing between all the transfer clamps 241.

[0058] The third adjustment mechanism 244 includes a third threaded screw 2442 and a second adjustment driver 2441. The two ends of the third threaded screw 2442 are respectively threadedly connected to the corresponding transfer clamps 241, and the threading directions are opposite. The second adjustment driver 2441 drives the third threaded screw 2442 to rotate.

[0059] In this embodiment, the second adjustment driver 2441 is a drive motor. By setting the number of rotations of the drive motor, the operator can transmit power through the third threaded screw 2442 and simultaneously adjust the spacing between all the transfer clamps 241.

[0060] In this embodiment, a transfer clamp 241 is threadedly connected to both ends of the third threaded screw 2442, so the thread structure at both ends of the third threaded screw 2442 has a uniform pitch. If two or more transfer clamps 241 are threadedly connected to both ends of the third threaded screw 2442, then the thread structure at both ends of the third threaded screw 2442 has a uniform pitch, and the thread structure at both ends needs to gradually increase the pitch from the inside to the outside, so that when the third threaded screw 2442 rotates, the transfer clamps 241 closer to the ends of the third threaded screw 2442 move a greater distance.

[0061] Preferably, one of the transfer clamps 241 is a fixed clamp 241a, which is not connected to the third adjustment mechanism 244. The third adjustment mechanism 244 connects and drives the other transfer clamps 241 to move relative to the fixed clamp 241a, so as to adjust the interval distance between the other transfer clamps 241 and the fixed clamp 241a.

[0062] Setting one of the transfer clamps 241 as a fixed clamp 241a that is not connected to the third adjustment mechanism 244 not only simplifies the transmission structure of the third adjustment mechanism 244, but also allows the position of the fixed clamp 241a to be used as a calibration reference. When adjusting the position of other transfer clamps 241, the relative position between the other transfer clamps 241 and the corresponding cutting mechanism 231 can be determined by the reference position of the fixed clamp 241a.

[0063] The transfer module 240 also includes a lifting mechanism 245. All transfer clamps 241 are mounted on the first forward mechanism 242 via the lifting mechanism 245 so that they can be lifted and lowered by the lifting mechanism 245.

[0064] The lifting mechanism 245 is mainly used to lower all the transfer clips 241 to the fabric inside the sewing device 100 after all the transfer clips 241 have been inserted into the sewing device 100, so that the strips inside all the transfer clips 241 can be placed more stably on the fabric.

[0065] Preferably, the transfer module 240 further includes at least one second forward mechanism 246, and at least one transfer clamp 241 is disposed on the first forward mechanism 242 or the lifting mechanism 245 through the corresponding second forward mechanism 246. The translation direction of the second forward mechanism 246 is parallel to the translation direction of the first forward mechanism 242. Each second forward mechanism 246 can drive the corresponding transfer clamp 241 to translate independently.

[0066] When different strips have different lengths, each second forward mechanism 246 drives the corresponding transfer clamp 241 to move independently according to the length of the corresponding strip, so as to adjust the front and rear positions of each transfer clamp 241, so that all transfer clamps 241 can clamp the raw material strips of different lengths after extending into the cutting module 230.

[0067] In this embodiment, the rotating mechanism 243 includes a rotating cylinder, and the first forward mechanism 242, the lifting mechanism 245, and the second forward mechanism 246 all include linear cylinders and corresponding guide rail assemblies.

[0068] like Figure 6The sewing device 100 includes a sewing table 110 and a sewing head 120, a clamping mechanism 130, a pressing mechanism 140, and a two-axis moving mechanism 150 disposed on the sewing table 110. The clamping mechanism 130, the pressing mechanism 140, and the two-axis moving mechanism 150 are located below the sewing head 120, and the clamping mechanism 130 and the pressing mechanism 140 are disposed on the two-axis moving mechanism 150, which simultaneously drives them to translate on the sewing plane.

[0069] When the fabric is fed to the sewing machine head 120 by the operator or the feeding robot, the clamping mechanism 130 clamps the fabric under the sewing machine head 120. When all the tapes are fed to the sewing machine head 120 by the transfer module 240, the pressing mechanism 140 presses all the tapes onto the fabric. Then, the two-axis moving mechanism 150 simultaneously drives the clamping mechanism 130 and the pressing mechanism 140 to translate on the sewing plane according to the sewing trajectory. The sewing machine head 120 then sews the fabric and tapes to cooperate with the translation of the two-axis moving mechanism 150, sewing all the tapes onto the fabric respectively.

[0070] The clamping mechanism 130 includes a base plate 131, a clamping plate 132, and a clamping drive assembly 133. The clamping drive assembly 133 drives the base plate 131 and the clamping plate 132 to move relative to each other, so as to press or release the fabric on the base plate 131. The pressing belt mechanism 140 is disposed on the clamping plate 132 and includes a pressing plate 141 and a pressing belt drive assembly 142. The pressing belt drive assembly 142 drives the pressing plate 141 to move relative to the clamping plate 132, so as to press or release all the belts on the fabric.

[0071] Preferably, the clamping plate 132 is provided with a plurality of clamping slots 1321 on the side facing the transfer module 240, and one clamping slot 1321 corresponds to one transfer clamp 241. When all transfer clamps 241 are moved to the underside of the sewing machine head 120, each transfer clamp 241 extends into the corresponding clamping slot 1321. Each transfer clamp 241 is provided with a pressing slot 2411 at its far end. The pressing plate 141 includes a plurality of pressing heads 1411. When all pressing heads 1411 move close to the clamping plate 132, each pressing head extends into the corresponding pressing slot 2411.
