Description

Technical Field

[0001] This utility model relates to the field of edge-locking technology, and specifically to an intelligent edge-locking machine. Background Technology

[0002] The current edge-sealing process for products such as armbands and shoulder patches is all done manually. During manual operation, there is no precise fixed position for edge sealing, resulting in poor edge uniformity and an unattractive appearance after the product is finished. Because it relies entirely on manual operation, the processing cost is high, the processing steps are cumbersome, the labor intensity is high, and the work efficiency is low, which does not meet the needs of automated production advocated by today's society.

[0003] To address this, a shoulder / armband binding machine (CN221421393U) has been proposed. It includes a machine body, a side wall plate on the side of the machine body opposite the needle, a needle plate below the needle, and a sewing table on the outside of the needle plate. The distance between the needle and the side wall plate is 14-14.8mm. An oil-proof cover is located at the lower outer part of the side wall plate to collect waste oil and allow it to flow into a waste oil channel. This shoulder / armband binding machine can bind the edges of shoulder patches and armbands, thereby improving work efficiency, reducing labor intensity, and meeting the demands of automated production advocated in today's society.

[0004] However, when binding / overlocking irregular products, the aforementioned epaulette / armband binding machine requires manual assistance to push the product and control the direction of the stitching to ensure that the spacing between the stitches and the edges is as equal as possible. However, manually pushing the product to control the stitching direction is inefficient and cannot guarantee that the stitching direction is always optimal. Slight errors can easily result in skewed stitches, compromising the quality of the binding / overlocking.

[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an intelligent overlock machine.

The presser wheel is located beside the presser foot and is used to press the product to be overlocked to cooperate with the needle plate teeth to control the movement direction of the product to be overlocked.

[0008] Furthermore, in the above technical solution, the detection module includes a detection swing arm that is mounted on the side of the workbench in a swingable manner and is used to contact the outer edge of the product to be edged, and a sensor mounted on the upper end of the detection swing arm and used to detect the swing amplitude of the detection swing arm.

[0009] Furthermore, in the above technical solution, a swing shaft is fixed in the middle of the detection swing rod. The swing shaft is installed in the connecting block in a swingable manner, and the connecting block is fixed to the machine head. The connecting block also has a swing groove that runs through the upper and lower end faces and the side. The detection swing rod is placed in the swing groove and can swing in the swing groove. The sensor is installed on the machine head in an adjustable relative position through a mounting bracket. A detection block is also provided at the upper end of the detection swing rod, and the detection block is located next to the sensor.

[0010] Furthermore, in the above technical solution, the detection block is provided with a through hole that passes through the upper and lower ends, and the side of the detection block is provided with a transverse screw hole that passes through the through hole. The detection block is sleeved on the upper end of the detection swing rod through the through hole, and the first screw spirals through the transverse screw hole and presses against the outer side of the upper end of the detection swing rod to fix the detection block to the upper end of the detection swing rod.

[0011] Furthermore, in the above technical solution, a support column is provided on the base, and the swing seat is mounted on the support column in a swingable manner through a hinge; a wire cutting module is provided at the front end of the workbench.

[0012] Furthermore, in the above technical solution, the first drive mechanism is fixed on the base, and the upper end of the first drive rod of the first drive mechanism is rotatably connected to the swing seat. The first drive mechanism is an electric push rod, a cylinder, or a hydraulic cylinder.

[0013] Furthermore, in the above technical solution, the lateral drive mechanism includes a lateral slide rail disposed on the swing seat, a lateral slider sleeved on the lateral slide rail, a threaded sleeve disposed in the lateral slider, a lead screw passing through the threaded sleeve, and a servo motor mounted on the swing seat for driving the lead screw to rotate. The lateral moving frame is fixed on the lateral slider.

[0014] Furthermore, in the above technical solution, the second drive mechanism includes a first drive wheel and a second drive wheel disposed at the upper and lower ends of the pressure arm, a transmission component connected between the first drive wheel and the second drive wheel, and a motor mounted on the transverse moving frame for driving the first drive wheel to rotate.

[0015] Furthermore, in the above technical solution, the second driving mechanism includes a motor disposed at the lower end of the pressure arm, and the rotating shaft of the motor is connected to the pressure roller to drive the pressure roller to rotate.

[0016] Furthermore, in the above technical solution, the pressure arm includes a first arm body and a second arm body with adjustable relative positions. The upper end of the second arm body is provided with a strip-shaped hole, and the lower end of the first arm body is provided with a first screw hole. The second screw passes through the strip-shaped hole and is screwed into the first screw hole for fixation.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: When the present invention is working, the product to be edged is placed on the worktable and placed on the upper end of the needle plate teeth, and then the presser foot presses the product to be edged. At the same time, the first drive mechanism of the auxiliary edge-locking device drives the swing seat, which in turn drives the press arm to press down, thereby pressing the press roller to press the product to be edged, so that the product to be edged is in close contact with the worktable. The detection module detects the position of the outer edge of the product to be edged in real time, determines that the outer edge of the product to be edged is in the optimal position, ensures that the spacing of the edge-locking is equal in the later stage, and thus ensures the edge-locking quality. Subsequently, the machine head works to sew the edges of the product to be overlocked, and the needle plate teeth cooperate to drive the product to be overlocked to move. At the same time, the second drive mechanism drives the pressure roller to rotate, which in turn assists the needle plate teeth in driving the product to be overlocked to move. Thus, the pressure roller not only presses down on the product to be overlocked to prevent local bulging and other defects during the overlocking process, but also assists the needle plate teeth in driving the product to be overlocked to move, thereby controlling the direction of the overlock stitch. It does not require manual operation, reduces labor intensity, avoids hand injuries, and ensures that the stitch direction of the product to be overlocked is always in the optimal direction, ensuring the quality of the overlock / overlocking. When overlocking the convex or concave edges of a product, the detection module detects whether the outer edge of the product is convex or concave and controls the second drive mechanism to drive the pressure roller to rotate counterclockwise or clockwise. At the same time, the auxiliary needle plate teeth continue to drive the product to be overlocked from front to back and control the rotation speed of the pressure roller, thereby driving the product to turn. This ensures that the machine head always sews at equidistant positions on the outer edge of the product to achieve equidistant binding / overlocking. It always ensures that the stitching direction of the product to be overlocked is in the optimal direction and there will be no skewing, thus guaranteeing the binding / overlocking quality of the product.

[0025] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0026] See Figure 1-7 The image shows an intelligent overlock machine, comprising a base 1, a worktable 2 mounted on the base 1 for supporting the product to be overlocked, a machine head 3 located beside the worktable 2 for overlocking the product, needle plate teeth 4 mounted on the worktable 2, and presser feet 5 adapted to the needle plate teeth 4. In operation, the product to be overlocked is placed on the worktable 2 and positioned on top of the needle plate teeth 4. The presser feet 5 then hold the product in place. The machine head 3 then operates to overlock the edges of the product, while the needle plate teeth 4 work in conjunction to move the product, continuously overlocking the edges. This is the working process of a conventional overlock machine and represents conventional technology.

[0027] The main improvements of this utility model are as follows: The base 1 is also provided with an auxiliary locking device 6, which includes a swing seat 61 mounted on the base 1 in a swingable manner and a first drive mechanism 62 for driving the swing seat 61 to swing, a transverse drive mechanism 63 mounted on the swing seat 61, a transverse moving frame 64 mounted on the transverse drive mechanism 63, a pressure arm 65 mounted on the transverse moving frame 64, a pressure roller 66 mounted at the end of the pressure arm 65 and distributed in a vertical direction, a detection module 67 located on the side of the workbench 2 for detecting the position of the outer edge of the product to be locked, and a second drive mechanism 68 for cooperating with the detection module 67 to control the pressure roller 66 to rotate clockwise / counterclockwise. The pressure roller 66 is located on the side of the pressure foot 5 and is used to press the product to be locked in order to cooperate with the needle plate teeth 4 to control the movement direction of the product to be locked.

[0028] The auxiliary overlocking device 6 plays an auxiliary role when the overlocking machine is overlocking the product to be overlocked. Specifically, the product to be overlocked is placed on the worktable 2 and placed on the upper end of the needle plate teeth 4. The presser foot 5 presses down on the product to be overlocked. At the same time, the first drive mechanism 62 of the auxiliary overlocking device 6 drives the swing seat 61, which in turn drives the press arm 65 to press down, thereby pressing the press roller 66 to press down on the product to be overlocked, so that the product to be overlocked is in close contact with the worktable 2. The detection module 67 detects the position of the outer edge of the product to be overlocked in real time, determines that the outer edge of the product to be overlocked is in the optimal position, ensures that the spacing of the overlocking is equal in the later stage, and thus ensures the quality of overlocking. Subsequently, the machine head 3 works to sew the edge of the product to be overlocked, and the needle plate teeth 4 cooperate to drive the product to be overlocked to move. At the same time, the second drive mechanism 68 drives the pressure roller 66 to rotate, thereby assisting the needle plate teeth 4 in driving the product to be overlocked to move. Thus, the pressure roller 66 not only presses down on the product to be overlocked to prevent local bulging and other defects during the overlocking process, but also assists the needle plate teeth 4 in driving the product to be overlocked to move, thereby controlling the direction of the overlocking stitch. It does not require manual operation, reduces labor intensity, avoids hand injuries, and ensures that the stitch direction of the product to be overlocked is always in the optimal direction, ensuring the quality of the overlocking / overlocking of the product. When overlocking the convex edge of the product to be overlocked, the detection module 67 detects that the outer edge of the product to be overlocked is a convex edge, and controls the second drive mechanism 68 to drive the pressure roller 66 to rotate counterclockwise. At the same time, the auxiliary needle plate teeth 4 continue to drive the product to be overlocked from front to back, and control the rotation speed of the pressure roller 66, thereby driving the product to be overlocked to turn, so that the machine head always sews at equidistant positions on the outer edge of the product to be overlocked to achieve equidistant binding / overlocking. Similarly, when overlocking the concave edge of the product to be overlocked, the detection module 67 detects that the outer edge of the product to be overlocked is a convex edge. The outer edge of the product is concave. The second drive mechanism 68 drives the pressure roller 66 to rotate clockwise. At the same time, the auxiliary needle plate teeth 4 continue to drive the product to be edged from front to back and control the rotation speed of the pressure roller 66. This allows the product to be edged to turn, so that the machine head always sews at equidistant positions on the outer edge of the product to be edged to achieve equidistant binding / locking. This ensures that the stitching direction of the product to be edged is always in the optimal direction and there will be no crooked stitching, thus ensuring the binding / locking quality of the product to be edged.

[0029] The function of the transverse drive mechanism 63 is to drive the pressure arm 65 and the pressure roller 66 at its lower end to move outward, thereby driving the product pressed by the pressure roller 66 and completed with the edge locking to move outward, so that the product with the edge locking is removed from the needle plate teeth 4, which facilitates the subsequent cutting and blanking of the product with the edge locking, and also provides enough space for the next product to be edge locked for edge locking processing.

[0030] A support column 11 is provided on the base 1, and the swing seat 61 is mounted on the support column 11 in a swingable manner through a hinge 611. Its assembly structure is simple. The hinge 611 can be a hinge or the like. A wire cutting module 21 is provided at the front end of the workbench 2. When the lateral drive mechanism 63 drives the pressure arm 65 and the pressure roller 66 at its lower end to move outward, the finished edge-locking product is moved outward. The lateral drive mechanism 63 also drives the pressure arm 65 and the pressure roller 66 at its lower end to reset. After the machine head performs stitching on the next product to be edge-locked, the stitching of the finished edge-locking product is still connected to the product to be edge-locked. As the product to be edge-locked rotates, the finished edge-locking product rotates along with the stitching and falls below the front end of the worktable 2. The stitching is straightened and falls into the thread-cutting module 21. The thread-cutting module 21 cuts the stitching, causing the finished edge-locking product to fall into the discharge hopper 10. The discharge hopper 10 is located on the lower side of the front end of the worktable 2 and below the thread-cutting module 21 to receive the finished edge-locking product.

[0031] The structure of the detection module 67 is described in detail below:

[0032] The detection module 67 includes a detection swing arm 671 mounted oscillatingly on the side of the workbench 2 for contacting the outer edge of the product to be edged, and a sensor 672 mounted on the upper end of the detection swing arm 671 for detecting the swing amplitude of the detection swing arm 671. During operation, when the product to be edged is in contact with the lower end of the detection swing arm 671, and the edge of the product shifts, the product will push the detection swing arm 671 to swing. At this time, the sensor 672 detects the swing amplitude of the detection swing arm 671, and then controls the rotation direction and speed of the second drive mechanism 68 driving the pressure roller 66. This assists the needle plate teeth 4 in driving the product to change its direction of movement, thereby adjusting the stitch direction of the product to be edged to always be in the optimal direction, so that the machine head always sews at equidistant positions on the outer edge of the product to achieve equidistant edge binding / locking.

[0033] Specifically, a swing shaft 673 is fixed in the middle of the detection swing rod 671. The swing shaft 673 is installed in the connecting block 674 in a swingable manner, and the connecting block 674 is fixed on the machine head 3. The connecting block 674 also has a swing groove 675 that runs through the upper and lower end faces and the side. The detection swing rod 671 is placed in the swing groove 675 and can swing in the swing groove 675 to ensure that the swing direction is in one direction and avoid deviation. The sensor 672 is installed on the machine head 3 in an adjustable relative position through a mounting bracket 676. The relative position of the sensor 672 can be adjusted by the mounting bracket 676 to improve the detection quality. A detection block 677 is also provided at the upper end of the detection swing rod 671. The detection block 677 is located next to the sensor 672. The sensor 672 can be a photoelectric sensor or the like. The detection block 677 is used to reflect the light emitted by the sensor 672, and the sensor 672 receives the reflected light to calculate the offset of the swing arm 671. This is a conventional technology and will not be described in detail here.

[0034] The detection block 677 is provided with a through hole 601 that passes through the upper and lower ends. The side of the detection block 677 is provided with a transverse screw hole 602 that passes through the through hole 601. The detection block 677 is sleeved on the upper end of the detection swing rod 671 through the through hole 601. The first screw spirals through the transverse screw hole 602 and presses against the outer side of the upper end of the detection swing rod 671 to fix the detection block 677 to the upper end of the detection swing rod 671. Its assembly structure is simple, its installation is convenient, and it is easy to adjust and maintain.

[0035] The first drive mechanism 62 is fixed to the base 1. The upper end of the first drive rod 621 of the first drive mechanism 62 is rotatably connected to the swing seat 61. The first drive mechanism 62 is an electric push rod, a pneumatic cylinder, or a hydraulic cylinder. In this embodiment, the first drive mechanism 62 is a pneumatic cylinder, which has a simple structure and low cost.

[0036] The lateral drive mechanism 63 includes a lateral slide rail 631 mounted on a swing base 61, a lateral slider 632 sleeved on the lateral slide rail 631, a threaded sleeve disposed in the lateral slider 632, a lead screw 633 passing through the threaded sleeve, and a servo motor 634 mounted on the swing base 61 for driving the lead screw 633 to rotate. The lateral moving frame 64 is fixed to the lateral slider 632. The lateral drive mechanism 63 has a simple structure and can accurately drive the lateral moving frame 64 to move laterally.

[0037] The second drive mechanism 68 may include at least two of the above structures:

[0038] The first structure is: combination Figure 6As shown, the second drive mechanism 68 includes a first drive wheel 681 and a second drive wheel 682 disposed at the upper and lower ends of the pressure arm 65, a transmission component 683 connected between the first drive wheel 681 and the second drive wheel 682, and a motor 684 mounted on the transverse moving frame 64 for driving the first drive wheel 681 to rotate. The first drive wheel 681 and the second drive wheel 682 are pulleys, and the transmission component 683 is a belt; alternatively, the first drive wheel 681 and the second drive wheel 682 are gears, and the transmission component 683 is a chain.

[0039] The second structure is as follows: the second drive mechanism 68 includes a motor disposed at the lower end of the pressure arm 65, and the rotating shaft of the motor is connected to the pressure roller 66 to drive the pressure roller 66 to rotate.

[0040] The pressure arm 65 includes a first arm body 651 and a second arm body 652 with adjustable relative positions. The upper end of the second arm body 652 is provided with a strip hole 603, and the lower end of the first arm body 651 is provided with a first screw hole 604. A second screw passes through the strip hole 603 and is screwed into the first screw hole 604 for fixation. Its assembly structure is simple, and the length of the entire pressure arm 65 is adjustable, which facilitates the adjustment of the pressure roller's pressing height.

[0041] In summary, during operation, the product to be edged is placed on the workbench 2 and positioned on the upper end of the needle plate teeth 4. The presser foot 5 then presses down on the product. Simultaneously, the first drive mechanism 62 of the auxiliary edge-locking device 6 drives the swing seat 61, which in turn drives the press arm 65 to press down, thereby pressing the press roller 66 against the product, ensuring that the product is tightly attached to the workbench 2. Furthermore, the detection module 67 detects the position of the outer edge of the product in real time, determining that the outer edge of the product is in the optimal position to ensure that the spacing of the subsequent edge-locking is equal, thus ensuring the edge-locking quality. Subsequently, the machine head 3 works to sew the edge of the product to be overlocked, and the needle plate teeth 4 cooperate to drive the product to be overlocked to move. At the same time, the second drive mechanism 68 drives the pressure roller 66 to rotate, thereby assisting the needle plate teeth 4 in driving the product to be overlocked to move. Thus, the pressure roller 66 not only presses down on the product to be overlocked to prevent local bulging and other defects during the overlocking process, but also assists the needle plate teeth 4 in driving the product to be overlocked to move, thereby controlling the direction of the overlocking stitch. It does not require manual operation, reduces labor intensity, avoids hand injuries, and ensures that the stitch direction of the product to be overlocked is always in the optimal direction, ensuring the quality of the overlocking / overlocking of the product. When overlocking the convex edge of the product to be overlocked, the detection module 67 detects that the outer edge of the product to be overlocked is a convex edge, and controls the second drive mechanism 68 to drive the pressure roller 66 to rotate counterclockwise. At the same time, the auxiliary needle plate teeth 4 continue to drive the product to be overlocked from front to back, and control the rotation speed of the pressure roller 66, thereby driving the product to be overlocked to turn, so that the machine head always sews at equidistant positions on the outer edge of the product to be overlocked to achieve equidistant binding / overlocking. Similarly, when overlocking the concave edge of the product to be overlocked, the detection module 67 detects that the outer edge of the product to be overlocked is a convex edge. The outer edge of the product is concave. The second drive mechanism 68 drives the pressure roller 66 to rotate clockwise. At the same time, the auxiliary needle plate teeth 4 continue to drive the product to be edged from front to back and control the rotation speed of the pressure roller 66. This allows the product to be edged to turn, so that the machine head always sews at equidistant positions on the outer edge of the product to be edged to achieve equidistant binding / locking. This ensures that the stitching direction of the product to be edged is always in the optimal direction and there will be no crooked stitching, thus ensuring the binding / locking quality of the product to be edged.
