Description

Technical Field

[0001] This invention relates to the field of rubber band processing equipment, specifically to a rubber band machine. Background Technology

[0002] The production of elastic band rings typically involves using bundles or rolls of elastic bands as raw materials, cutting them into sections, and sewing them into rings. This production process is usually completed manually or by operating multiple single machines with different functions separately.

[0003] Existing elastic band cutting machines have two cutting methods when cutting fabric: ordinary cutting blades and ultrasonic cutting blades. Due to the need to adjust the cutting requirements, improve cutting efficiency and quality, or reduce costs, it is necessary to change to different cutting blade methods. When switching between the two cutting blades, the entire cutting device needs to be replaced because the two cutting blades have different structures.

[0004] For example, an automatic rubber band machine disclosed in Chinese patent application CN201920429727.X cuts rubber bands using an ultrasonic cutting device. The ultrasonic cutting device includes an upper cutting blade assembly and a lower anvil mold assembly that work together. When the ultrasonic cutting device needs to be replaced with a regular cutting blade, both the upper cutting blade assembly and the lower anvil mold assembly need to be completely disassembled and replaced.

[0005] For example, Chinese patent application CN202020890751.6 discloses a rubber band machine, which has a cutting assembly on the frame of the material conveying device. The cutting assembly includes a moving blade and a blade holder arranged opposite each other. The moving blade is connected to a second power source and moves up and down to cut the material on the blade holder. When it is necessary to replace the cutting assembly with an ultrasonic cutter, the entire cutting assembly needs to be removed from the frame.

[0006] In conclusion, whether replacing the ultrasonic cutter with a regular cutter or vice versa, the entire cutting device needs to be replaced, leading to inconvenience in operation. Summary of the Invention

[0019] The outstanding and beneficial technical effects of this invention compared to the prior art are:

[0020] 1. The moving blade mechanism designed in this invention can be adapted to two different fixed blade mechanisms. By adjusting the tilt angle of the moving blade, the moving blade can cooperate with ordinary blades or ultrasonic cutters to cut the fabric. When it is necessary to switch between ordinary cutters and ultrasonic cutters, only the fixed blade mechanism needs to be replaced and the guide can be installed or removed. There is no need to replace the entire moving blade mechanism, which is convenient to operate.

[0021] 2. The material handling device designed in this invention can straighten out piles and bundles of elastic bands. When the elastic band gets stuck, the elastic band machine can be started and stopped by the sensor and the material handling rod, which ensures that the elastic bands fed into the feeding device are neat and thus ensures the yield rate of the elastic bands after they are sewn into the elastic band rings.

[0022] 3. The present invention is designed with an adjustment component to adjust the tilt angle of the pulling device on the workbench, so that when the pulling device moves the elastic band to the clamping and flipping device, the position of the elastic band will not tilt, thereby ensuring that the two ends of the elastic band can be aligned after flipping, and ensuring the yield rate of the elastic band after sewing.

[0023] 4. The clamping and flipping device designed in this invention adjusts the orientation of the clamping components by adjusting component two, so that after the two clamping components clamp and flip the two ends of the elastic band, the distance between the two sides of the elastic band is the same, avoiding the two ends of the elastic band being too close to each other on one side and too far apart on the other side, thus ensuring the aesthetics of the elastic band after sewing.

[0024] 5. The moving blade of the present invention has three-dimensional adjustment methods: First, the adjustment of the connecting plate on the support frame (adjustment plate on the support frame) can be raised and lowered or tilted, which is the first level of adjustment; Second, pressing the pressure cap can switch the moving blade between the upper and lower positions, which is the second level of adjustment; Third, rotating the connecting sleeve allows for fine adjustment of the position of the connecting sleeve on the crossbeam, which is the third level of adjustment; thereby making the cutting device suitable for cutting rubber bands of different material types and thicknesses.

[0050] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. See also Figures 1-24 .

[0051] Example 1, see Figures 1-10 ,as well as Figures 15-24 :

[0052] Combination Figure 1 and Figure 2 A rubber band machine includes: a workbench 1; a material handling device 2, installed on the side of the workbench 1, for handling rubber band strips; a feeding device 3, installed on the workbench 1, for conveying the rubber band strips to a cutting area 40; a cutting device 4, installed on the side of the feeding device 3, and having a cutting area 40 inside, wherein the rubber band strips conveyed by the feeding device 3 pass through the cutting area 40 and are cut by the cutting device 4; and a pulling device 5, installed on the workbench 1 and located to the side of the cutting device 4, for clamping the rubber band strips exiting from the cutting area 40. The device includes a flipping area 60; a clamping and flipping device 6, which is installed on a workbench 1 between the cutting device 4 and the pulling device 5, and the clamping and flipping device 6 has a flipping area 60. The clamping and flipping device 6 is used to clamp and flip the two ends of the elastic band located in the flipping area 60 so that the two ends of the elastic band are aligned; and a sewing device (a sewing machine in the prior art), which is installed on a workbench 1 located at the front end of the clamping and flipping device 6, for sewing the two ends of the elastic band after they have been flipped and aligned by the clamping and flipping device 6, thereby sewing the elastic band into an elastic band ring.

[0053] Combination Figures 3-10The cutting device 4 includes: a support frame 11, which is mounted on the workbench 1; a moving blade mechanism 41, which is mounted on the support frame 11 and positioned above the feeding device 3; and a fixed blade mechanism 42, which is mounted on the support frame 11 and positioned below the feeding device 3. The moving blade mechanism 41 and the fixed blade mechanism 42 form a cutting area 40. The moving blade mechanism 41 has: a sliding plate 411, whose two ends are slidably placed in vertical grooves 460 on both sides of the support frame 11; and a moving blade 412, which is mounted on the sliding plate 411 and has several slotted holes 425. Screws, bolts, or pins pass through the slotted holes 425 and are connected to the sliding plate 411. The moving blade 412 is adjusted by adjusting the position of the screws, bolts, or pins in the slotted holes 425. The tilt angle on the sliding plate 411; the guide 415, which is mounted on the sliding plate 411 and is located at the side end of the moving blade 412, with the lower end of the guide 415 lower than the lower end of the moving blade 412; the adjustment assembly 43, which is movably disposed on the upper end of the support frame 11; and two drive components 413 (which are drive cylinders or linear motors), which are mounted on the adjustment assembly 43 and whose drive ends are movably connected to the left and right ends of the sliding plate 411 respectively, for making the sliding plate 411 slide up and down in the vertical slide groove 460; by adjusting the fixed position of the adjustment assembly 43 on the support frame 11, the positions of the two drive components 413 on the left and right sides of the support frame 11 are adjusted, thereby changing the tilt angle of the sliding plate 411 and thus adjusting the tilt angle of the moving blade 412.

[0054] The ordinary cutter or ultrasonic cutter can be adjusted by changing the fixed blade mechanism 42. When using the ordinary cutter, the tilt angle of the moving blade 412 is adjusted so that there is a certain angle between the lower edge of the moving blade 412 and the fixed blade 422. At the same time, the guide 415 is installed on the sliding plate 411, so that the moving blade 412 can cooperate with the fixed blade 422 of the fixed blade mechanism 42 to cut the fabric. When using the ultrasonic cutter, the tilt angle of the moving blade 412 is adjusted so that the lower edge of the moving blade 412 and the anvil are at a certain angle. The upper surface of the bottom mold 424 is parallel, and the guide 415 is removed from the sliding plate 411, so that the moving blade 412 can work with the bottom mold 424 to cut the elastic band. When the cutting device 4 is changed between a regular cutter and an ultrasonic cutter, it is not necessary to disassemble the entire moving blade mechanism 41. Only the fixed blade mechanism 42 needs to be replaced, which is convenient to operate. One set of moving blade mechanism 41 can be adapted to a regular cutter or an ultrasonic cutter. It has strong adaptability and does not require an additional set of moving blade mechanism 41, saving production costs.

[0055] Meanwhile, when using a regular cutter, the angle between the moving blade 412 and the fixed blade 422 affects the cutting effect of the elastic band. To adapt to elastic bands of different thicknesses or materials, it is necessary to change the angle between the moving blade 412 and the fixed blade 422. The fixed blade 422 is generally directly fixed on the fixed plate 421 (i.e., the blade of the fixed blade 422 is horizontally set). Therefore, it is necessary to change the tilt angle of the moving blade 412 to adjust the angle between the moving blade 412 and the fixed blade 422. This solution provides two adjustment methods for users to choose from: adjusting the tilt angle of the moving blade 412 after it is installed on the sliding plate 411 through the strip hole 425 on the moving blade 412, or adjusting the tilt angle of the sliding plate 411 and the moving blade 412 as a whole through the adjustment component 43. This allows the tilt angle of the moving blade 412 to increase to cope with thicker or more difficult-to-cut elastic bands, ensuring the cutting effect of the elastic band and avoiding situations where the elastic band cannot be cut.

[0056] When the fixed blade mechanism 42 uses a common cutter, the guide 415 is installed on the sliding plate 411. When the sliding plate 411 moves down, the guide surface formed on the lower side of the guide 415 will contact the upper blade of the fixed blade 422, so that the side of the guide 415 slides against the front end face of the fixed blade 422, thereby avoiding direct collision between the blades of the moving blade 412 and the fixed blade 422, which would cause damage to the blades and ensure the service life and safety of the blades.

[0057] Combination Figures 3-5The adjustment assembly 43 includes: two adjustment plates 431, each with an oblong hole. Adjustment plates 431 are mounted on the support frame 11 by means of fasteners (bolts, screws, or pins) passing through the oblong holes and being fixed to the left and right sides of the support frame 11. The fasteners can slide within the oblong holes by adjusting their tightness. Each adjustment plate 431 is connected to a driving member 413. A connecting plate 432 is movably connected to the sliding plate 411 in its middle, and its two ends are hinged to the driving ends of the two driving members 413. The connecting plate 432 has connecting holes 4321 at both ends for driving the driving members 413. The hinge shaft on the end moves within the connecting hole 4321. To ensure that both ends of the connecting plate 432 can be connected to the driving end of the driving component 413 after tilting, the connecting hole 4321 is an oblong hole or the diameter of the connecting hole 4321 is large enough to allow the hinge shaft to move within the connecting hole 4321. By adjusting the position of the two adjusting plates 431 on the side of the corresponding support frame 11, the connecting plate 432 is tilted, which drives the sliding plate 411 to tilt, thereby adjusting the tilt angle of the moving blade 412. Thus, after the tilt angle of the moving blade 412 is changed, it can not only be used to adapt to different fixed blade mechanisms 42, but also to adapt to cut rubber bands of different thicknesses or materials.

[0058] To ensure the service life of the moving blade 412 after it is installed on the sliding plate 411, this design includes a second pressure plate 414 movably connected to the sliding plate 411. The second pressure plate 414 presses against the moving blade 412 to fix it to the sliding plate 411. Both the second pressure plate 414 and the sliding plate 411 have corresponding connecting holes, and fasteners (screws, bolts, or pins) are installed in the connecting holes. The middle part of the fastener passes through the first slot 425 of the moving blade 412. The two ends of the fastener connect the second pressure plate 414 and the sliding plate 411 respectively, reducing the gap between the second pressure plate 414 and the sliding plate 411 to clamp and fix the moving blade 412. The second pressure plate 414 prevents the fastener from directly pressing against the edge of the first slot 425 of the moving blade 412, which would cause the moving blade 412 to be stressed and worn, thus ensuring the service life of the moving blade 412.

[0059] Combination Figures 3-5The support frame 11 is provided with a mounting plate 46, and a moving blade mechanism 41 is mounted on the mounting plate 46. Limiting protrusions 461 are vertically provided at both ends of the mounting plate 46. A pressure plate 462 is provided on the end side of each limiting protrusion 461. The side end of the pressure plate 462 protrudes from the side end of the limiting protrusion 461 and forms a vertical sliding groove 460 between it and the mounting plate 46. Sufficient space exists between the bottoms of the vertical sliding grooves 460 on both sides of the support frame 11 for placing the sliding plate 411 when it is cut at an angle (the sliding plate 411 is a cuboid). When tilted, it can be placed between two vertical slide grooves 460, and regardless of whether the sliding plate 411 is tilted, a portion of the side end of the sliding plate 411 is placed within the vertical slide groove 460; wherein, a fixing pin 47 is connected to the limiting protrusion 461, the fixing pin 47 passes through the pressure plate 462, and a compression spring 471 is sleeved on the fixing pin 47, the compression spring 471 movably abuts against the pressure plate 462, so that the pressure plate 462 movably presses against the front ends of the sliding plate 411 on both sides; when using a common cutter, as the cutter moves As the blade 412 moves downward, the guide 415 abuts against the front end face of the fixed blade 422. This causes the pressure plate 462 on the side closer to the guide 415 to move forward and compress the compression spring 471. Meanwhile, the pressure plate 462 away from the guide 415 presses against the side end of the sliding plate 411 under the pressure of the compression spring 471. This causes one side of the sliding plate 411 to tilt towards the front end face, resulting in the moving blade 412 rotating forward. This ensures that when the moving blade 412 moves downward, the cutting edge of the moving blade 412 and the cutting edge of the fixed blade 422 are in contact. The blades will always partially abut against each other, ensuring that there is a shearing force between the moving blade 412 and the fixed blade 422 to cut the rubber band. At the same time, as the moving blade 412 moves downward, the pressure plate 462 on the side away from the guide 415 will also move forward to compress the compression spring 471, ensuring the shearing force between the moving blade 412 and the fixed blade 422, while avoiding excessive friction between the moving blade 412 and the fixed blade 422, reducing the wear of the moving blade 412 and increasing its service life.

[0060] Combination Figures 3-5The moving blade mechanism 41 has a width limiting component 44, which is placed within the cutting area 40. The width limiting component 44 includes: an adjusting rod 441, which passes through a limiting protrusion 461 on one side of the support frame 11, and a limiting member 443 is provided on the end side of the adjusting rod 441, with a limiting part 445 on the limiting member 443; and an adjusting rod 442, which passes through a limiting protrusion 461 on the other side of the support frame 11, and a limiting member 444 is provided on the end side of the adjusting rod 442, with a limiting part 446 on the limiting member 444. By adjusting the adjusting rod 442... The positions of the first section rod 441 and the second adjustment rod 442 on the support frame 11 allow the first limiting part 445 and the second limiting part 446 to move and abut against the side end of the elastic band, and allow the first limiting part 443 and the second limiting part 444 to move and abut against the upper end of the elastic band, limiting the swaying of the elastic band and ensuring that the ends of the elastic band are neat after cutting. The positions of the first adjustment rod 441 and the second adjustment rod 442 on the support frame 11 are manually adjusted so that the first limiting part 445 and the second limiting part 446 can better abut against both ends of the elastic band and avoid excessive pressure that could cause the elastic band to deform.

[0061] Combination Figures 6-8 The fixed blade mechanism 42 includes: a fixed plate 421, which is disposed on the support frame 11 and is located below the feeding device 3; a fixed blade 422, which is mounted on the fixed plate 421, and when the moving blade 412 of the moving blade mechanism 41 moves downward, a shearing force is formed between the fixed blade 422 and the moving blade 412 to cut the elastic band; or, the fixed blade mechanism 42 includes: a fixed frame 12, which is mounted on the lower end of the support frame 11; an ultrasonic generator 423, which is mounted on the fixed frame 12; and an anvil bottom mold 424, which is mounted on the ultrasonic generator 423 and is located at the lower end of the moving blade 412, and the anvil bottom mold 424 and the moving blade 412 cut the elastic band.

[0062] Combination Figures 3-5The support frame 11 is provided with a limiting component 45, which includes: a limiting rod 451, which passes through the crossbeam 463 at the upper end of the support frame 11, and the lower end of the limiting rod 451 is movably connected to the upper end of the sliding plate 411 (the lower end of the limiting rod 451 is hinged to the upper end of the sliding plate 411 or threaded to the sliding plate 411. When threaded, the gap of the threads on the sliding plate 411 is larger, thereby ensuring that the limiting rod 451 can swing on the sliding plate 411 without disengaging); and several fixing parts 452, which are threaded to the limiting rod 451. On rod 451, and fixing part 452 movably abuts against the upper end of crossbeam 463 of support frame 11, to limit the movement range of sliding plate 411 on support frame 11; when using ultrasonic cutter, the force of moving blade 412 against the bottom mold of cutting board 424 should not be too large, otherwise it will easily cause wear of bottom mold of cutting board 424. Therefore, by adjusting the position of fixing part 452 on limiting rod 451, the downward movement position of limiting rod 451 is limited. Limiting rod 451 limits the downward movement range of sliding plate 411, thereby avoiding excessive force of moving blade 412 pressing against bottom mold of cutting board 424.

[0063] The drive end of the drive component 413 is threadedly connected to a hinge seat 433. The end of the hinge seat 433 has a hinge groove 4331. Hinges 4332 are provided opposite to each other on both sides of the hinge groove 4331. The end of the connecting plate 432 is movably placed in the hinge groove 4331 and hinged to the hinge hole 4332. The hinge groove 4331 has space for the connecting plate 432 to rotate around the hinge hole 4332.

[0064] Combination Figure 15 and Figure 16The material handling device 2 includes: a shaping frame 21 located on the side of the workbench 1; a shaping plate assembly 22 installed inside the shaping frame 21, with a shaping channel 221 vertically arranged inside the shaping plate assembly 22; a material feeding assembly 23 located at the upper end of the shaping frame 21 for feeding the elastic band to the upper end of the shaping channel 221; a transmission pressure roller assembly 24 located on the shaping frame 21 below the shaping channel 221; and a material guide rod 25, the middle of which is rotatably mounted on the shaping frame 21 below the transmission pressure roller assembly 24, and the front end of the material guide rod 25 has a feeding mechanism. The elastic band passes through a feed inlet 251, and the rear end of the feed rod 25 has a sensing part 250; a sensing device 26 is disposed on the shaping frame 21 corresponding to the movement trajectory of the sensing part 250, and the sensing device 26 has a sensing area 261 and a sensing area 262; when the feed rod 25 rotates, the sensing part 250 cooperates with the sensing area 261 or the sensing area 262 to control the start and stop of the elastic band machine. The machine will only start or stop when the sensing device 26 senses the sensing part 250, to prevent the elastic band from being blown by the wind and triggering the sensing device 26; when When the elastic band is conveyed by the feeding device 3, the length of the elastic band between the feeding device 3 and the transmission pressure roller assembly 24 gradually decreases. The elastic band lifts the feed inlet 251 at the front end of the feeder rod 25, causing the feeder rod 25 to rotate. This places the sensing part 250 within the sensing area 261. After the sensing device 26 senses the sensing part 250 through the sensing area 261, it activates the feeding assembly 23 to feed the elastic band, thus feeding it. However, if the elastic band gets stuck due to improper alignment, the elastic band... The length of the rubber band decreases further due to untimely supply, causing the sensing part 250 to be placed in the sensing area 262. After the sensing device 26 senses the sensing part 250 through the sensing area 262, the entire machine will stop working. At this time, after the rubber band is straightened manually, the sensing part 250 will be removed from the sensing area 262, and the sensing device 26 will restart the rubber band machine. The sensing device 26 can feed the rubber band in a timely manner and can also prevent the rubber band from being torn due to the machine continuing to run after the rubber band is stuck, thus ensuring the safety and stability of feeding.

[0065] Combination Figure 15 and Figure 16The material feeding assembly 23 includes: a connecting frame 231, which is installed on the upper end of the shaping frame 21; a triangular wheel 232, which is rotatably connected to the connecting frame 231; a second driving component 233 (a motor or a rotary cylinder), which is installed on the connecting frame 231 and is used to drive the triangular wheel 232 to rotate; a first straightening rod 234, which is installed on the connecting frame 231; and a second straightening rod 235, which is installed on the connecting frame 231. When the elastic band moves between the first straightening rod 234 and the second straightening rod 235 through the triangular wheel 232, the first straightening rod 234 presses against the upper surface of the elastic band, and the second straightening rod 235 presses against the lower surface of the elastic band, thereby straightening the elastic band.

[0066] Two limiting elements 236 are provided on the straightening rod 235 to prevent the rubber band from detaching from the straightening rod 235.

[0067] A roller 252 is fitted on one side edge of the feed inlet 251. When the elastic band moves, the roller 252 rotates, thereby reducing the friction between the elastic band and the edge of the feed inlet 251 and preventing the elastic band from being pulled and deformed.

[0068] The shaping plate assembly 22 includes: a first shaping plate 222, which is vertically mounted on the shaping frame 21; and a second shaping plate 223, which is vertically movably connected to the shaping frame 21, forming a shaping channel 221 between the second shaping plate 223 and the first shaping plate 222. The shaping frame 21 has a guide hole 211, through which a guide rod 224 passes, the end of which is connected to the side end of the second shaping plate 223. The shaping frame 21 is equipped with a third driving component 225 (a cylinder or linear motor), the driving end of which is movably connected to the second shaping plate 223, used to adjust the width of the shaping channel 221. The first shaping plate 222 and the second shaping plate 223 respectively compress the elastic band, making the elastic band flat and ensuring the aesthetic appearance of the sewn elastic band.

[0069] The transmission pressure roller assembly 24 includes: a rotating frame 241, the middle of which is hinged to the shaping frame 21; a first roller 242, which is rotatably connected to the front end of the rotating frame 241; a second roller 243, which is rotatably connected to the shaping frame 21 and movably abuts against the first roller 242; and a fourth driving component 244 (which is a rotary cylinder or motor), which is mounted on the rotating frame 241 and is used to drive the second roller 243 to rotate.

[0070] A connecting rod 245 is provided on the shaping frame 21. A tension spring is connected to the rear end of the rotating frame 241 via the connecting rod 245, which is used to allow the first roller 242 to move against the second roller 243, thereby ensuring that the second roller 243 can drive the elastic band to move when it rotates.

[0071] The rotating frame 241 is provided with two limiting members 246 to prevent the elastic band from disengaging from between roller 1 242 and roller 243.

[0072] Combination Figure 17 and Figure 18 The material pulling device 5 includes: a second mounting plate 51, which is mounted on the worktable 1; a clamping assembly 52, which is mounted on the second mounting plate 51, for clamping the elastic band passing through the cutting area 40; and at least two sets of adjusting assemblies 53, which are disposed at both ends of the second mounting plate 51 and connected to both ends of the clamping assembly 52, for adjusting the orientation of the clamping assembly 52 on the second mounting plate 51 to avoid situations such as... Figure 19 Regarding the issue of the elastic band 9, when there are more than two sets of adjustment components 53, the stability of the connection between the mounting plate 2 51 and the clamping component 52 can be improved. Each adjustment component 53 includes: an adjustment frame 531 mounted on the mounting plate 2 51; at least two adjustment members 534 threadedly connected to the adjustment frame 531 and distributed at both ends of the strip hole 2 5371, with the lower end of the adjustment member 534 movably abutting against the mounting plate 2 51; and an adjustment rod 3 535 movably connected to the adjustment frame 531, and adjusting... The end of the third section 535 is movably connected to the clamping assembly 52; by adjusting the position of the adjusting piece 534 and the third section 535 on the adjusting frame 531, the orientation of the clamping assembly 52 on the mounting plate 51 is adjusted, ensuring that the elastic band can be pulled out parallel when the clamping assembly 52 clamps the elastic band coming out of the cutting area 40. This ensures that the two ends of the elastic band 9 can be aligned after flipping, improving the aesthetics of the elastic band after sewing it into an elastic band ring and avoiding the defect of misalignment after flipping the two ends of the elastic band 9 (such as...). Figure 19 (The problems presented in the text).

[0073] The adjusting frame 531 includes: a horizontal plate 537 with a strip-shaped hole 5371 and several adjusting holes 532, the adjusting holes 532 being distributed on both sides of the strip-shaped hole 5371; a vertical plate 538, vertically positioned above the horizontal plate 537, with a through hole 533; a fixing component four (a screw, bolt, or pin) connected to the strip-shaped hole 5371, the fixing component four connecting to the mounting plate 51; an adjusting component 534 movably connected to the adjusting hole 532; and an adjusting rod 535 movably connected to the through hole 533; by adjusting the position of the adjusting component 534 within the adjusting hole 532, the lower end of the adjusting component 534 abuts against the mounting plate 51, causing the horizontal plate 537 to tilt, thereby tilting the adjusting frame 531 and adjusting the tilt angle of the clamping assembly 52 on the adjusting frame 531 (e.g., ...). Figure 17(Adjust the rotation angle of the clamping assembly 52 in the plane of the X and Z axes); when only one set of adjusting components 53 is adjusted, the rotation adjustment of the clamping assembly 52 in the plane of the Y and Z axes is achieved; by adjusting the position of the adjusting rod 3 535 in the through hole 533, the lengths of the adjusting rod 3 535 extending out of the through hole 533 in the two sets of adjusting components 53 are different, thereby achieving the adjustment of the rotation angle of the clamping assembly 52 in the plane of the X and Y axes, ensuring that the elastic band will not tilt when it is taken out, and avoiding misalignment of the two ends after the elastic band 9 is sewn into an elastic band ring.

[0074] Adjusting rod 3 535 is inserted into through hole 533, and several fixing parts 2 536 are threadedly connected to adjusting rod 3 535. Fixing parts 2 536 are movably abutted against both sides of vertical plate 538 to restrict the movement of adjusting rod 3 535 in through hole 533.

[0075] The adjusting component 534 is threadedly connected to a fixing component 539, which movably abuts against the horizontal plate 537, ensuring the connection strength of the adjusting component 534 and preventing the adjusting component 534 from moving within the adjusting hole 532.

[0076] Combination Figures 22-24 The clamping and flipping device 6 includes: a mounting frame 61; two rotary drive sources 62 (motors or rotary motors) arranged side by side on the mounting frame 61, and a clamping assembly 63 is provided on the output end of the rotary drive source 62; an adjustment assembly 64, which is disposed between the rotary drive source 62 and the mounting frame 61, for mounting the rotary drive source 62 onto the mounting frame 61; and a slide rail assembly, which is mounted on the worktable 1, for driving the mounting frame 61 to move on the worktable 1, thereby moving the elastic band with both ends flipped into the sewing machine for sewing; wherein, the adjustment assembly 64 includes: an adjustment plate 641, which is movably connected to the mounting frame 61, and the rotary drive source 62 is mounted on the adjustment plate 641; and a plurality of adjustment pins 642, which pass through the periphery of the adjustment plate 641, and the ends of the adjustment pins 642 movably abut against the mounting frame 61, and the adjustment pins 642 are threadedly connected to the adjustment plate 641.

[0077] The adjusting pin 642 is threadedly connected to a fixing member 643, and the fixing member 643 moves against the adjusting plate 641 to prevent the adjusting pin 642 from disengaging from the adjusting plate 641.

[0078] Adjusting plate 641 and mounting bracket 61 are connected and fixed by screws, bolts, or pins. By adjusting the position of the adjusting pins 642 at the four corners of adjusting plate 641, the length of the front end of the adjusting pin 642 extending out of adjusting plate 641 is adjusted, thereby changing the distance between the periphery of adjusting plate 641 and mounting bracket 61, and thus adjusting the tilt angle of the rotary drive source 62 on adjusting plate 641. This ensures that after the two clamping assemblies 63 clamp the two ends of the elastic band and flip the two ends of the elastic band through the rotary drive source 62, the two ends of the elastic band are parallel, ensuring the aesthetics of the elastic band after sewing it to the elastic band ring and avoiding defects such as... Figure 20 and Figure 21 The problem of uneven distances between the two ends of the elastic band appears in the process.

[0079] The clamp assembly 63 includes: a first clamping plate 631, which is movably connected to the drive end of the rotary drive source 62; a second clamping plate 632, which is movably placed on the first clamping plate 631; and a sixth drive member 633 (which is a cylinder or a linear motor), which is movably connected to the first clamping plate 631, and the drive end of the sixth drive member 633 passes through the first clamping plate 631 and is movably connected to the second clamping plate 632; the second clamping plate 632 is driven to move closer to or away from the first clamping plate 631 by the sixth drive member 633, thereby clamping the elastic band between the first clamping plate 631 and the second clamping plate 632.

[0080] A connector 65 is movably connected to the drive end of the rotary drive source 62, and the connector 65 is movably connected to a clamping plate 631. The connector 65 has a clamping part 651 and a clamping part 652, and a connecting hole 2 is formed between the clamping part 651 and the clamping part 652. A fixing member 6 (which is a screw, bolt or pin) passes through the clamping part 651 and the clamping part 652. The clamping part 651 and the clamping part 652 are brought closer to each other through the fixing member 6, thereby fixing the drive end of the rotary drive source 62 in the connecting hole 2.

[0081] The upper end of the mounting bracket 61 is provided with several air blowing pipes 66, and the air blowing ends of the air blowing pipes 66 are bent and aligned with the space between the two clamping assemblies 63.

[0082] Combination Figure 5 , Figure 9 and Figure 10 The feeding device 3 includes: a first roller 31, which is rotatably connected to the support frame 11; a second roller 32, which is rotatably connected to the support frame 11 and the second roller 32 movably abuts against the first roller 31; a rotating assembly 33, which is mounted on the support frame 11 and is used to drive the first roller 31 to rotate; a rotating assembly 34, which is mounted on the support frame 11 and is used to drive the second roller 32 to press against the first roller 31; and a metering assembly 35, which is mounted on the support frame 11 and is used to measure the conveying length of the elastic band.

[0083] The rotating assembly 33 has a motor, a first transmission wheel, a second transmission wheel, and a transmission belt. The first transmission wheel rotates through the motor drive end, and the first transmission wheel drives the second transmission wheel to rotate through the transmission belt. The second transmission wheel drives the first roller 31 to rotate.

[0084] The rotating assembly 34 has a drive cylinder, a transmission block, and a rotating frame. The drive cylinder is mounted on the support frame 11. The horizontal shaft on the rotating frame is connected to the support frame 11. The transmission block connects the horizontal shaft and the drive end of the drive cylinder. The second roller 32 is rotatably connected to the end of the rotating frame away from the horizontal shaft. The drive cylinder drives the transmission block to rotate around the horizontal shaft, thereby causing the transmission block to drive the rotating frame to rotate, so that the second roller 32 presses against the first roller 31.

[0085] The metering component 35 is specifically described in the structure disclosed in Chinese patent application CN201920430316.2, and will not be repeated here.

[0086] Example 2, see Figures 11-14 :

[0087] The design scheme of this embodiment is basically the same as that of Embodiment 1, except that:

[0088] Combination Figures 11-14 The support frame 11 is provided with a limiting component 48, which includes: a connecting sleeve 481, which is threadedly connected to the upper end of the support frame 11. The inner wall of the connecting sleeve 481 has a plurality of circumferentially distributed guide blocks 4811. The ends of the guide blocks 4811 are all formed with inclined guide surfaces 4812. The guide blocks 4811 are interleaved with limiting grooves 4813 and limiting grooves 4814; and a driving sleeve 482, whose outer wall has circumferentially distributed limiting blocks 4821. The limiting blocks 4821 slide within the limiting grooves 4813, and the ends of the driving sleeve 482 have a plurality of circumferentially distributed guide grooves 4822. The two side walls of 4822 are inclined toward the opening of the guide groove 4822; the rotating sleeve 483 is rotatably disposed in the connecting sleeve 481, and the outer wall of the rotating sleeve 483 has several circumferentially distributed linkage blocks 4831, the ends of the linkage blocks 4831 are all formed with inclined guide surfaces 4832, and the guide surfaces 4832 can fit with the guide surfaces 4812; the elastic element 484 is a spring or disc spring, which is sleeved on the guide rod 485, and the two ends of the elastic element 484 abut against the sliding plate 411 and the rotating sleeve 483 respectively, so that the linkage block 4831 is placed in the limiting groove 4813 or the limiting groove 4814 and abuts against the drive sleeve 482;

[0089] When the drive sleeve 482 is pressed, the drive sleeve 482 pushes the rotating sleeve 483 forward, and the linkage block 4831 is placed in the guide groove 4822 through the guide surface 4832. When the linkage block 4831 disengages from the limiting groove 4813 and the drive sleeve 482 is released, the elastic element 484 drives the rotating sleeve 483 to move backward, so that the linkage block 4831 slides into the limiting groove 4814 through the guide surface 4812. At this time, the rotating sleeve 483 is in the second position in the connecting sleeve 481. After the drive sleeve 482 is pressed again and released, the linkage block 4831 moves from the limiting groove 4814 to the limiting groove 4813. At this time, the rotating sleeve 483 is in the first position in the connecting sleeve 481.

[0090] Combination Figure 11 and Figure 12 A guide rod 485 is engaged at the upper end of the sliding plate 411. The guide rod 485 passes through the first elastic element 484, the drive sleeve 482, and the rotating sleeve 483 in sequence. A pressure cap 4891 is connected to the upper end of the guide rod 485. The lower end of the pressure cap 4891 movably abuts against the upper end of the drive sleeve 482 to push the drive sleeve 482 downward. A plane bearing 4895 is provided between the first elastic element 484 and the rotating sleeve 483. A second elastic element 4892 (a spring or disc spring) is sleeved on the guide rod 485, and the second elastic element 4892 movably abuts against the pressure cap 4891 and the connecting sleeve 481 respectively. The elastic force of the second elastic element 4892 is greater than that of the first elastic element 484, so that the guide rod 485 has an upward tendency.

[0091] When the drive sleeve 482 is pressed, causing the rotating sleeve 483 to move from the first position to the second position within the connecting sleeve 481, the rotating sleeve 483 is located at a lower position within the connecting sleeve 481. The elastic element 484 is compressed to a greater extent, thereby pushing the sliding plate 411 downward. After the sliding plate 411 moves downward, it will drive the guide rod 485 downward and cause the pressure cap 4891 to squeeze the elastic element 4892. This results in the guide rod 485 being initially positioned lower, ultimately causing the moving blade 412 on the sliding plate 411 to have a shorter downward cutting stroke. This ensures greater force when cutting the fabric and guarantees the cutting effect on thicker or harder elastic bands.

[0092] When the drive sleeve 482 is pressed, causing the rotating sleeve 483 to move from the second position to the first position within the connecting sleeve 481, the rotating sleeve 483 is located at the upper part of the connecting sleeve 481. The elastic element 484 is compressed by a small amount. Since the elastic force of the elastic element 4892 is greater than that of the elastic element 484, the guide rod 485 moves upward, thereby driving the sliding plate 411 to move upward. This results in the guide rod 485 being initially positioned higher, ultimately causing the moving blade 412 on the sliding plate 411 to have a longer downward cutting stroke. This ensures that the force required to cut the fabric is smaller, allowing the cutter to cut thinner or softer materials, thus improving the cutting effect.

[0093] The elastic element 4892 can also prevent the pressure cap 4891 and the connecting sleeve 481 from colliding when the cutting is completed, thus reducing noise.

[0094] When the driving component 413 is a cylinder, a one-way pressure valve is installed on the cylinder's air intake pipe. When the pressure inside the cylinder reaches a set value, the internal gas is discharged through the one-way pressure valve. During actual operation, the moving blade 412 moves downward and performs cutting work. The pressure accumulated in the elastic component 4892 gradually increases. After cutting is completed, the pressure of the elastic component 484 and the elastic component 4892 and the pressure inside the cylinder reach equilibrium, and the cylinder stops moving downward, thus preventing the moving blade 412 from moving too far. After the cylinder finishes working, the elastic component 484 and the elastic component 4892 reset, realizing the upward reset of the moving blade 412.

[0095] The lower outer wall of the connecting sleeve 481 has a threaded portion 4893, which is used to adjust the position of the connecting sleeve 481 on the crossbeam 463 on the support frame 11, thereby adjusting the initial position of the limiting component 48 on the support frame 11 and realizing the adjustment of the initial position of the moving blade 412.

[0096] The moving blade of this invention has three adjustment methods: First, the adjustment of the connecting plate on the support frame (adjustment plate on the support frame) allows for both lifting and tilting adjustment, which is the first level of adjustment; Second, pressing the pressure cap switches the moving blade between its upper and lower positions, which is the second level of adjustment; Third, rotating the connecting sleeve allows for fine adjustment of its position on the crossbeam, which is the third level of adjustment. This makes the cutting device suitable for cutting elastic bands of different material types and thicknesses.
