[0032] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] See also Figure 1 , Figure 2The utility model provides an automatic cutting machine for measuring towel templates, comprising: a machine platform 1, a sewing machine 2 arranged on the machine platform 1, a measuring towel guiding mechanism 3 arranged beside the sewing machine 2, and a feeding module 4 arranged at the front end of the measuring towel guiding mechanism 3, the measuring towel guiding mechanism 3 comprising: an overhead bracket 31 arranged on the sewing machine 2, a plurality of guide rings 32, an anti-rolling device 33, a shrinking mechanism 34 and a traction mechanism 35 arranged on the overhead bracket 31, an automatic lifting and shearing device 6 and a bowl-shaped presser foot 36 arranged below the sewing machine 2, the measuring towel 5 to be sewn is drawn out from the feeding module 4, bypasses the guide ring 32, the anti-rolling device 33, the traction mechanism 35 and the shrinking mechanism 34 on the overhead bracket 31 in sequence and extends to the bowl-shaped presser foot 36, and the shrinking mechanism 34 is arranged at a position close to the bowl-shaped presser foot 36.

[0034] The towel 5 passes through the anti-roller 33 in a winding manner, which can prevent the towel 5 from twisting during the feeding process, thereby ensuring that the towel 5 can be transmitted in a plane output state. The number of turns of the towel 5 wound on the anti-roller 33 is adjusted to control the tension tightness of the towel 5 during the conveying process. If the number of turns of the towel 5 wound on the anti-roller 33 is more, the resistance of the towel 5 passing through the anti-roller 33 will be greater, so that the tension on the towel 5 is greater, so when the sewing machine 2 sews the towel 5 on the cut piece, the tightness of the towel 5 will also be tighter. On the contrary, if the number of turns of the towel 5 wound on the anti-roller 33 is less, the resistance of the towel 5 passing through the anti-roller 33 will be smaller, so that the tension on the towel 5 is smaller, so when the sewing machine 2 sews the towel 5 on the cut piece, the tightness of the towel 5 will also be looser.

[0035] At the same time, a shrinking mechanism 34 is set at a position close to the bowl-shaped presser foot 36. The shrinking mechanism is synchronized with the X-axis of the sewing machine. According to the length of the towel 5 required for the sewing machine 2 to sew the current towel 5, that is, the moving distance on the X-axis, the corresponding length of the towel 5 is released through the shrinking mechanism 34 to meet the sewing needs of the towel 5, and when the shrinking mechanism does not supply the towel 5, the towel 5 is tightened to effectively ensure the tension applied to the towel 5.

[0036] After the sewing machine 2 sews the towel 5 to the cloth through the template, the automatic lifting and shearing device 6 is started to cut the towel 5, so as to realize the automatic template-based sewing and shearing of the towel 5. Compared with the method in the prior art that requires manual cutting and then stretching the towel and sewing it through the sewing machine, the utility model provides a towel length that is the same as the X-axis moving distance through the shrinking mechanism 34, which is convenient for the sewing machine to sew. At the same time, since the towel 5 is pulled and produces elasticity during the sewing process, the towel 5 is in a stretched state when sewn on the cloth. Therefore, by controlling the tension on the towel 5, the length of the towel 5 meets the requirements of the cloth sewing process after the stitched towel 5 is cut under the action of the automatic lifting and shearing device 6 and shrinks under its own elasticity.

[0037] By automatically supplying the measuring towel 5, stretching, sewing and cutting the measuring towel 5, the template-type measuring towel 5 sewing process is realized, and the manpower input of the operator is reduced, thereby effectively improving the production efficiency and meeting the needs of mass production and processing.

[0038] See also Figure 3 The shrinking mechanism 34 includes: a shrinking bracket 341 arranged on the overhead bracket 31, a shrinking drive motor 342 arranged on the shrinking bracket 341, an active rubber roller 343 connected to the output end of the shrinking drive motor 342, a pressure wheel bracket 344 hinged on the shrinking bracket 341, and a shrinking pressure wheel 345 arranged on the pressure wheel bracket 344, the shrinking pressure wheel 345 is movably attached to the active rubber roller 343, a limiting wheel 346 is arranged on the hinged position between the pressure wheel bracket 344 and the shrinking bracket 341, and a limiting groove 3461 is arranged on the cylindrical surface of the limiting wheel 346 along the circumferential direction. After the traction mechanism 35 extracts the measuring towel 5 from the feeding module 4, the measuring towel 5 will be suspended on the measuring towel guide mechanism 3 at a certain length. When the sewing machine is sewing the towel 5 on the cloth, as the X-axis moves, the shrinking drive motor 342 is started, driving the active rubber roller 343 to start, pulling the towel 5 forward for transportation, thereby releasing the towel 5 of a length corresponding to the moving distance of the X-axis. At the same time, since the shrinking pressing wheel 345 presses the towel between the shrinking pressing wheel 345 and the active rubber roller 343, a large pressure is applied to the towel 5, which not only meets the need to pull and feed the towel 5 through the active rubber roller 343, but also provides tension for the sewing of the towel 5, meeting the tension requirement for sewing the towel 5 to the cloth. At the same time, by passing the towel 5 around the limiting wheel 346 and then passing through the active rubber roller 343 and the shrinking pressing wheel 345 for feeding, the limiting groove 3461 on the limiting wheel 346 provides the towel 5 with a limit and guide, thereby preventing the towel 5 from being offset.

[0039] See also Figure 4The anti-roller 33 is a wavy curved strip, and the towel 5 passes through the wavy curved strip of the anti-roller 33 in a winding manner. By using the wavy curved strip as the anti-roller 33, it is convenient for the towel 5 to be wound on the anti-roller 33, and the number of turns of the towel 5 wound on the anti-roller 33 can be changed according to the tightness of the towel 5 required for processing, so as to meet the requirements of the towel 5 for deviation correction, anti-rolling and anti-twisting during the processing, so that the towel 5 can be output in a plane, so that the towel 5 can be sewed by the sewing machine 2 later, and the finished product yield can be affected by the twisting of the towel.

[0040] A wire management box 334 is provided at one end of the anti-roller 33. After the towel 5 passes through the anti-roller 33, it passes through the wire management box 333 and extends forward. By providing the wire management box 333 fixed to the rear end of the anti-roller 33, after the towel 5 passes through the anti-roller 33, the towel 5 passes through the wire management box 333. The wire management box 333 is provided with a towel through hole 334 corresponding to the width and thickness of the towel 5, thereby preventing the towel 5 from sliding at the rear end of the anti-roller 33 and falling off the anti-roller 33, and ensuring that the output position of the towel 5 after passing through the anti-roller 33 is stable. When a tensioner 34 is provided at the rear end of the anti-roller 33, the tensioner 34 can directly play the role of the wire management box 333.

[0041] A fixing ring 331 is provided at one end of the anti-roll device 33 and the guide ring 32, and a threaded hole 332 is provided on the side wall of the fixing ring 331. By providing the fixing ring 331 on the anti-roll device 33 and the guide ring 32, it is convenient to sleeve the anti-roll device 33 or the guide ring 32 on the overhead bracket 31, and by screwing a screw into the threaded hole 332, the end of the screw is pressed against the overhead bracket 31, so as to achieve the installation and fixation of the anti-roll device 33 or the guide ring 32. At the same time, when the screw is loosened, the fixing ring 331 can rotate around the cantilever of the overhead bracket 31, and then the screw is locked and fixed to meet the adjustment of the feeding angle of the towel 5.

[0042] See also Figure 5The traction mechanism 35 includes: a traction drive motor 351 disposed on the overhead support 31, an active rubber roller 352 connected to the output end of the traction drive motor 351, a pressure adjustment rod 353 hinged on the overhead support 31, a driven pressure wheel 354 rotatably connected to the pressure adjustment rod 353, and an electrostatic eliminator 355 disposed on the overhead support 31, wherein the pressure adjustment rod 353 rotates around the hinge position to drive the driven pressure wheel 354 to approach or move away from the active rubber roller 352. The electrostatic eliminator 355 contacts the towel 5, thereby eliminating the static electricity on the towel 5 through the electrostatic eliminator 355, preventing the towel 5 from sticking due to static electricity, and avoiding the adhesion from affecting the feeding of the towel 5. During operation, the measuring cloth 5 passes between the active rubber roller 352 and the driven pressure wheel 354. When the traction drive motor 351 is started, the traction drive motor 351 drives the active rubber roller 352 to rotate, and through the meshing transmission between the active rubber roller 352 and the driven pressure wheel 354, the effect of pulling and pulling the measuring cloth 5 is achieved. By adjusting the position of the pressure adjustment rod 353, the distance between the driven pressure wheel 354 and the active rubber roller 352 is changed, thereby changing the pressure between the driven pressure wheel 354 and the active rubber roller 352. The greater the pressure between the active rubber roller 352 and the driven pressure wheel 354, the greater the traction force applied to the measuring cloth 5, which meets the demand for pulling and feeding the measuring cloth 5.

[0043] The towel guiding mechanism 3 further includes: a suspended counterweight block 37, a detection sensor 38 disposed on the overhead bracket 31, and a towel hooking mechanism 39 disposed beside the bowl-shaped presser foot.

[0044] The cloth 5 bypasses the counterweight 37, and the counterweight 37 presses the cloth 5 downward so that the cloth 5 is in a tensioned state. After the traction mechanism 35 pumps the cloth 5, the cloth 5 will be suspended on the overhead bracket 31 in a U-shaped structure, which is convenient for the sewing machine 2 to sew the cut pieces. At the same time, when the template machine drives the template loaded with the cut pieces to move, it will pull the cloth 5 suspended on the overhead bracket 31 to feed the material, thereby meeting the sewing requirements of the cut pieces and the cloth 5, avoiding the situation in which the cloth 5 is pulled due to the untimely or asynchronous feeding of the cloth by the traction mechanism 2 during the sewing process, resulting in a change in the tension of the cloth 5 during the sewing process. By using the counterweight 37 to suppress the U-shaped structure formed by the cloth 5 hanging on the overhead bracket 31, the U-shaped cloth 5 will not be twisted, and the cloth 5 is provided with tension. By replacing the counterweights 37 of different weights, the tension on the hanging towel 5 can be adjusted, thereby adjusting the tightness of the towel 5 sewn on the cut piece.

[0045] The detection end of the detection sensor 38 faces the towel 5 wound on the counterweight 37. When the sewing machine 2 sews the towel 5 on the cut piece, as the sewing proceeds, the hanging U-shaped structure of the towel 5 section will be pulled, so that the length of the section of the towel 5 is gradually shortened, and the counterweight 37 moves upward. When the lowest position of the section of the towel 5 moves to a position higher than the detection sensor 38 as the length of the towel 5 is reduced, the detection sensor 38 does not detect the towel 5, and sends corresponding detection information to the control system. After receiving the detection information, the control system sends a corresponding control signal to the traction drive motor 351 of the traction mechanism 35, starts the traction drive motor 351, and thus pulls and extracts the towel 5 from the feeding module 4, so that the towel 5 is re-formed into a hanging U-shaped structure under the pressure of the counterweight 37, meeting the material demand for the towel 5 in the subsequent sewing work.

[0046] See also Figure 6 The hook mechanism 39 includes: a hook fixing plate 391 provided on the sewing machine 2, a hook adjusting block 392 provided on the hook fixing plate 391, a hook driving cylinder 393 provided on the hook adjusting block 392 away from the sewing machine 2, a hook fixing block 394 connected to the output end of the hook driving cylinder 393, and a hook 395 provided on the hook fixing block 394, wherein the hook 395 is bent inwardly at the end close to the sewing machine 2, and the cloth 5 passes through the bent part of the hook 395. If the cloth 5 does not need to be sewed and fixed to the cut piece to be sewn in the current sewing process, the hook driving cylinder 393 retracts, and the cloth 5 under the bowl-shaped presser foot 36 is pulled to the side to avoid the position through the hook 395, thereby avoiding the cloth 5 from being sewn on the cut piece during the sewing operation, and meeting the needs of different sewing processes.

[0047] The hook adjusting block 392 is provided with a plurality of hook adjusting strip holes 3921 along the output direction of the hook driving cylinder 393. The hook adjusting block 392 is connected and fixed to the hook fixing plate 391 by screws passing through the hook adjusting strip holes 3921 and being locked to the bottom of the hook fixing plate 391. The hook fixing block 394 is provided with hook fixing threaded holes 3941 corresponding to the hook 395 on the side wall. The hook fixing block 394 is locked in the hook fixing threaded holes 3941 by screws, so that the end of the screw is pressed against the hook 395, thereby installing and fixing the hook 395. When it is necessary to adjust the gripping position of the hook claw 395, the screw connecting the hook claw adjustment block 392 and the hook towel fixing plate 391 can be loosened, and the hook claw adjustment block 392 can be pushed and pulled along the direction of the hook claw adjustment strip hole 3921. After the hook claw 395 is moved to the corresponding setting position, the screw can be tightened at the bottom of the hook towel fixing plate 391 to lock and fix the hook claw adjustment block 392 to prevent the hook claw 395 from colliding with the sewing machine 2 or other mechanisms under the drive of the hook claw driving cylinder 393.

[0048] At the same time, loosen the screw screwed into the claw fixing threaded hole 3941, loosen the top fixing of the claw 395, adjust the fixed position of the claw 395 on the claw fixing block 394, and then lock the screw in the claw fixing threaded hole 3941 to fix the position of the claw 395. By adjusting the setting position of the claw 395, the pulling action requirements of the hook mechanism 39 on the towel 5 in different processes are met, and the situation of sewing the towel to the cloth in the process where the towel 5 does not need to be sewn is avoided, so that different sewing processes can be realized on the same sewing machine, and the number of equipment invested in the overall process of product forming is reduced, or the number of repeated placement, movement and other operations on the product is reduced, effectively saving production costs and improving production efficiency, while avoiding the influence of repeated placement and other operations on product yield, thereby improving product yield.

[0049] See also Figure 7 , the feeding module 4 adopts a roll material feeding module 41 or a bulk material feeding module 42. The towel material is generally stored and preserved in two ways: a towel roll material and a shake-bag type towel. The towel roll material is in the form of winding the towel 5 on a reel. During feeding, as the towel 5 is pumped, the entire roll of towel material will rotate. Therefore, during feeding, the towel roll material needs to be hung to ensure the smooth pumping process of the towel 5. The shake-bag type towel is to arrange the towel 5 in a stacked manner, and then put the towel 5 into a packaging bag or a packaging box. During feeding, it is necessary to open the packaging bag or the packaging box, and pull out one end of the towel 5 to meet the pumping and feeding needs of the towel 5.

[0050] The coil material feeding module 41 includes: a feeding fixed bracket 411 arranged on the overhead bracket 31 or the sewing machine 2, and a barrel 412 arranged on the feeding fixed bracket 411, and the barrel 412 can be movably sleeved with a cloth coil. In the embodiment provided by the utility model, when a cloth coil is used for feeding, the cloth coil is sleeved on the barrel 412, and the front end of the cloth 5 is drawn out from the cloth coil, passes through the anti-roll device 33 at the top of the overhead bracket 31, and then passes between the active rubber roller 352 and the driven pressure wheel 354, and then passes through a plurality of fixed rings 32, passes through the clamping position of the rear pneumatic clamp 39 and the shrinking mechanism 34, and then penetrates into the bowl-shaped presser foot 36, so as to facilitate the sewing machine 2 to perform sewing processing.

[0051] The bulk material feeding module 42 includes a material box placed on the machine 1 or beside the machine 1, and a shaking bag type towel is placed in the material box. In the embodiment provided by the utility model, when the shaking bag type towel is used for feeding, the shaking bag type towel is placed on the machine 1, or the shaking bag type towel is placed beside the machine 1, and the front end of the towel 5 is pulled out from the shaking bag type towel, passes through the anti-roller 33 on the top of the overhead bracket 31, and then passes between the active rubber roller 352 and the driven pressure wheel 354, and then passes through a plurality of fixed rings 32, passes through the clamping position of the rear pneumatic clamp 39 and a plurality of anti-rollers 33 with tensioners 34, and then penetrates into the bowl-shaped presser foot 36, so as to facilitate the sewing machine 2 to perform sewing processing.

[0052] In different embodiments, the user may use the coil feeding module 41 or the material box for feeding according to usage requirements, thereby performing corresponding customized assembly according to the user's usage habits to improve the applicability of the towel template machine.

[0053] See also Figure 8 An automatic lifting and shearing device 6 is provided below the sewing machine 2. The automatic lifting and shearing device 6 is provided at one end of the bowl-shaped presser foot 36 away from the towel guide mechanism 3. The automatic lifting and shearing device 6 comprises: a lifting bracket 61 provided on the sewing machine 2, a clamping claw lifting cylinder 62 provided on the lifting bracket 61, a pneumatic clamping claw 63 connected to the output end of the clamping claw lifting cylinder 62, a scissor lifting cylinder 64 provided on the lifting bracket 61, and a pneumatic scissor 65 provided on the output end of the scissor lifting cylinder 64, the pneumatic clamping claw 63 is close to the bowl-shaped presser foot 26, and the pneumatic scissor 65 is provided on the side of the pneumatic clamping claw 63 away from the bowl-shaped presser foot 36. After the sewing machine 2 completes the sewing of the towel 5 and the cut piece, the clamping claw lifting cylinder 62 extends, drives the pneumatic clamping claw 63 to move to the corresponding position of the towel 5 to be sheared, and starts the pneumatic clamping claw 63 to clamp and fix the towel 5 to ensure the stability of the towel 5. Then the scissor lifting cylinder 64 extends out, driving the blade of the pneumatic scissors 65 to move to the corresponding position of the towel 5, and the pneumatic scissors 65 are started to cut the towel 5, thereby completing the sewing of the cut pieces and the towel 5, facilitating the sewing of the next set of cut pieces and the towel 5, and improving the automation degree of the overall work, reducing manual participation and operation.

[0054] The pneumatic clamp 63 and the pneumatic scissors 65 form an inclination angle with the machine 1, so that the pneumatic clamp 63 and the pneumatic scissors 65 can be moved to the front end of the stitching position of the cut piece and the towel 5 by the clamp lifting cylinder 62 and the scissor lifting cylinder 64, respectively, to cut the unstitched towel 5. At the same time, the inclined setting can make the working position of the pneumatic clamp 63 and the pneumatic scissors 65 nearly vertical to the lifted and tilted towel 5, thereby improving the clamping and cutting effect of the towel 5.

[0055] After the sewing machine 2 completes the sewing of the towel 5 on the template, the template will continue to move a distance, and at the same time the bowl-shaped presser foot 36 is lifted upward, so that the towel 5 is tilted upward at a certain angle and extends upward, making it easier for the pneumatic clamp 63 to clamp and fix the towel 5, thereby cutting the towel 5 through the pneumatic scissors 65.

[0056] In actual work, in order to ensure the shearing effect of the pneumatic scissors 65 on the towel 5, when the pneumatic scissors 65 are started for shearing, the pneumatic scissors 65 are started and reset several times to ensure that the towel 5 is cut off to avoid affecting the subsequent sewing work between the cut piece and the towel 5.

[0057] See also Figure 8 , Fig. 9 The bowl-shaped presser foot 36 comprises: a presser foot lifting cylinder 361 arranged on the sewing machine 2, a presser foot main body 362 arranged on the output end of the presser foot lifting cylinder 361, and a cloth fixing device 363 arranged on the side wall of the presser foot main body 362. The center of the presser foot main body 362 is provided with a clearance hole 364 corresponding to the sewing needle position of the sewing machine 2. The presser foot main body 362 is provided with a cloth limiting groove 365 on the other side of the presser foot main body 362 relative to the cloth fixing device 363. The cloth limiting groove 365 is connected to the clearance hole 364. When sewing, the presser foot lifting cylinder 361 is pushed out to drive the presser foot main body 362 to move downward, so that the cloth 5 is pressed against the sewing hole opened on the template corresponding to the cutting piece through the presser foot main body 362. Then the sewing machine 2 is started, and the sewing needle performs up and down reciprocating motion to realize the sewing work. At the same time, the moving mechanism arranged on the machine table 1 of the template machine drives the template to move, thereby moving the template position and transporting the cutting piece forward.
