Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to an overlock machine. Background Technology

[0002] In the garment manufacturing process, since materials such as polyester are generally synthetic fibers, their texture is relatively stiff. After cutting, the threads at the seams of the cut fabric tend to fray due to their high stiffness. Therefore, overlocking is necessary: ​​a special overlocking machine is used to overlock the seams to prevent the threads in the fabric from fraying. This also serves an aesthetic purpose.

[0003] In the existing technology, overlock machines are mostly equipped with a machine body and a worktable. The machine body is set on the worktable and has a pressure plate and pressure needles that are movable. There are two sets of pedals on the worktable. The pedals are linked to the pressure plate and pressure needles respectively, so that the pressure plate and pressure needles are moved by the user's foot movements to perform the overlock operation. In addition, the user manually moves the fabric to be processed through the pressure plate and pressure needles to perform the overlock operation.

[0004] However, existing overlock machines require workers to move the fabric with both hands during overlocking. After the fabric is processed, workers also need to manually pick up the fabric and use scissors to cut the thread that is still connected to the presser after overlocking. The operation is cumbersome and affects the efficiency of overlocking. Utility Model Content

[0005] To improve the efficiency of edge copying, this application provides an edge copying machine.

[0006] The overlock machine provided in this application adopts the following technical solution: An overlock machine includes a worktable and a machine body. The machine body is mounted on the worktable and has a work plate connected to the worktable. A pressure plate and a pressure needle are slidably mounted on the machine body. The pressure plate is used to press fabric onto the work plate, and the pressure needle is used to thread the fabric for overlocking. The worktable is rotatably equipped with a first pedal and a second pedal. The first pedal is used to move the pressure plate up and down, and the second pedal is used to move the pressure needle back and forth. A cutting tool for cutting the thread is slidably mounted on the side wall of the pressure plate. The pressure plate is equipped with a drive assembly for driving the cutting tool to move and cut the thread.

[0007] By adopting the above technical solution, the staff steps on the first and second pedals to control the pressure plate and pressure needle to move up and down, respectively. This, combined with manually moving the fabric on the work plate, is used for overlocking. After the fabric is overlocked, the drive assembly moves the cutter to cut the thread end. This eliminates the need to manually pick up and use scissors to cut the thread end, reducing labor intensity and increasing the thread cutting speed, thereby improving overlocking efficiency.

[0008] Preferably, two cutting tools are provided, and the driving assembly is used to drive the two cutting tools to move in opposite directions or towards each other.

[0009] By adopting the above technical solution, two sets of cutters move towards each other to cut the wire ends, which improves the stability of wire end cutting, reduces the probability of the wire ends not being completely cut off after the cutters move, thereby reducing the number of times the wire ends need to be manually cut off during rework, and further improving the edge cutting efficiency.

[0010] Preferably, the drive assembly includes a drive motor, a first drive screw, a second drive screw, a first drive block, and a second drive block. The first and second drive screws are rotatably mounted on the pressure plate. The first and second drive screws are connected and have opposite threads. The first and second drive blocks are slidably mounted on the pressure plate. One of the cutting tools is connected to the first drive block, and the other cutting tool is connected to the second drive block. The first drive screw is threaded through the first drive block, and the second drive screw is threaded through the second drive block. The drive motor is mounted on the pressure plate, and the drive motor shaft is connected to the first drive screw.

[0011] By adopting the above technical solution, after the drive motor starts, it drives the first drive screw and the second drive screw to rotate. Because the threads are different, the first drive block and the second drive block move in opposite directions or towards each other, thereby driving the tool to move in opposite directions or towards each other. Only the motor needs to be started, making the operation simple, convenient and easy to use.

[0012] Preferably, the pressure plate is provided with a drive groove, the first drive screw and the second drive screw are both rotatably disposed in the drive groove, the first drive block and the second drive block are both slidably disposed in the drive groove, the side wall of the pressure plate is provided with a moving groove communicating with the drive groove, and the cutting tool is slidably disposed in the moving groove.

[0013] By adopting the above technical solution, both the first driving block and the second driving block are slidably disposed in the driving groove, which improves the stability of the movement of the first driving block and the second driving block, and the tool is slidably disposed in the moving groove, which improves the stability of the tool movement.

[0014] Preferably, the work plate is equipped with a photoelectric sensor, and the worktable is equipped with a controller. The controller is connected to the photoelectric sensor and the drive motor. The photoelectric sensor is used to detect the position of the fabric moving on the work plate, and the controller is used to start the drive motor according to the detection result of the photoelectric sensor.

[0015] By adopting the above technical solution, the photoelectric sensor is used to detect the position of the fabric on the work plate. After the fabric has finished the overlocking process and no longer blocks the photoelectric sensor, the controller starts the drive motor according to the detection result of the photoelectric sensor, thereby driving the cutter to move and cut the thread end, realizing automatic thread cutting, further improving the convenience of thread cutting, saving thread cutting time, and thus further improving the overlocking efficiency.

[0016] Preferably, the controller is signal-connected to both the first pedal and the second pedal, and the controller starts the drive motor according to the rotation state of the first pedal, the rotation state of the second pedal, and the detection result of the photoelectric sensor.

[0017] By adopting the above technical solution, the rotation states of the first pedal and the second pedal are both input to the controller. The controller only starts the drive motor after the photoelectric sensor detects that the fabric overlocking is completed before the first pedal drives the pressure plate to move up and the second pedal drives the pressure needle to move up. This ensures that the pressure plate presses the fabric onto the work plate during cutting, thus guaranteeing the stability of the fabric. At the same time, the upward movement of the pressure needle will not interfere with the movement of the cutter, thereby improving the stability of the cutting.

[0018] Preferably, the working plate is provided with a mounting plate, and the mounting plate is provided with a light-emitting block, which is aligned with the photoelectric sensor.

[0019] By adopting the above technical solution, the light-emitting block is aligned with the photoelectric sensor to improve the stability of the photoelectric sensor detection.

[0020] Preferably, the working plate is provided with a limiting plate, and the mounting plate is provided on the limiting plate. The limiting plate is used to limit the fabric being processed.

[0021] By adopting the above technical solution, the limiting plate limits the processed fabric, improves the stability of the fabric movement, reduces the offset during the fabric movement, and thus improves the stability of the fabric overlock position.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a worktable, machine body, work plate, pressure needle, pressure plate, first pedal, second pedal, cutter and drive assembly, the operator steps on the first pedal and second pedal on the worktable, which respectively drive the pressure needle and pressure plate on the machine body to move. In conjunction with the hand, the operator moves the fabric on the work plate to perform overlocking. After overlocking is completed, the drive assembly drives the cutter to move and cut the thread ends. There is no need to manually pick up and use scissors to cut the thread ends, which reduces labor intensity and increases the thread cutting speed, thereby improving overlocking efficiency. 2. By setting up a drive motor, a first drive screw, a second drive screw, a first drive block, and a second drive block, the drive motor drives the first drive screw and the second drive screw to rotate after starting. The screw drives the first drive block and the second drive block to move in opposite directions or towards each other, thereby driving the tool to move in opposite directions or towards each other, thus realizing tool driving. The operation is simple and convenient, and easy to use. 3. By setting up a controller, a light-emitting block, and a photoelectric sensor, the fabric moves between the light-emitting block and the photoelectric sensor. The photoelectric sensor detects the movement position of the fabric. The controller only starts the drive motor after the first pedal moves the pressure plate upward and the second pedal moves the pressure needle upward, based on the photoelectric sensor detecting that the fabric overlocking is complete. This ensures that the pressure plate presses the fabric onto the work plate during cutting, guaranteeing the stability of the fabric. At the same time, the upward movement of the pressure needle will not interfere with the movement of the cutter, improving the stability of the cutting. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses an edge-sealing machine. (Refer to...) Figures 1 to 3The device includes a workbench 1 and a machine body 2. A work plate 23 is fixedly mounted on the machine body 2. A pressure plate 21 and a pressure needle 22 are pneumatically slidably mounted on the machine body 2. The pressure plate 21 presses the fabric onto the work plate 23, and the pressure needle 22, after being threaded, moves back and forth to overlock the fabric. A first pedal 11 and a second pedal 12 are rotatably mounted on the bottom of the workbench 1. Both pedals 11 and 12 are connected to the machine body 2 via connecting rods. The first pedal 11 drives the pressure plate 21 to move up and down, and the second pedal 12 drives the pressure needle 22 to move back and forth. A moving groove 212 is provided on the side wall of the pressure plate 21 near the pressure needle 22. Two cutters 3 protrude from the moving groove 212 for cutting thread ends. A drive assembly 4 is provided on the pressure plate 21, which drives the two cutters 3 to move in opposite directions or towards each other. By using the drive assembly 4 to move the cutters 3 to cut the thread, no additional action is required from the operator, reducing labor intensity, increasing speed, and improving overlock efficiency.

[0030] For ease of use, please refer to Figure 3 The drive assembly 4 includes a drive motor 41, a first drive screw 42, a second drive screw 43, a first drive block 44, and a second drive block 45. The pressure plate 21 has a drive groove 211 communicating with the moving groove 212. Both the first drive screw 42 and the second drive screw 43 are rotatably mounted within the drive groove 211, with opposite threads and coaxially fixedly connected. The first drive block 44 is slidably mounted within the drive groove 211 and fixedly connected to one of the cutting tools 3. The second drive block 45 is slidably mounted within the drive groove 211 and fixedly connected to the other cutting tool 3. The first drive screw 42 is threaded through the first drive block 44, and the second drive screw 43 is threaded through the second drive block 45. After the drive motor 41 starts, it drives the first drive screw 42 and the second drive screw 43 to rotate. Through the threads, the first drive block 44 and the second drive block 45 move in opposite directions or towards each other, thereby driving the cutting tools 3 to move in opposite directions or towards each other, achieving tool driving. The operation is simple and convenient, making it easy to use.

[0031] To further improve the efficiency of edge copying, refer to Figures 2 to 4A limit plate 5 is provided on the side of the working plate 23 near the machine body 2 to limit the movement of the fabric on the working plate 23. An L-shaped mounting plate 51 is fixedly installed on the limit plate 5. A light-emitting block 52 for emitting light is provided on the bottom wall of the mounting plate 51. A photoelectric sensor 61 for detecting the movement position of the fabric is provided on the surface of the working plate 23 directly below the light-emitting block 52. The machine body 2 is provided with a controller 6 that is signal-connected to both the photoelectric sensor 61 and the drive motor 41. The connecting rods inside the machine body 2 that are connected to the first pedal 11 and the second pedal 12 are all equipped with angle sensors that are signal-connected to the controller 6, so that the controller 6 can determine the rotation state of the first pedal 11 and the second pedal 12 through the angle sensors. The controller 6 starts the drive motor 41 according to the rotation state of the first pedal 11, the rotation state of the second pedal 12 and the detection result of the photoelectric sensor 61. This allows the controller 6 to start the drive motor 41 before the first pedal 11 moves the pressure plate 21 upward and after the second pedal 12 moves the pressure needle 22 upward, based on the photoelectric sensor 61 detecting that the overlocking of the fabric is completed, to cut the thread ends and automatically improve the efficiency of overlocking.

[0032] The implementation principle of the overlock machine in this application embodiment is as follows: When the overlocking of the fabric is about to be completed, the fabric moves away from the photoelectric sensor 61. The photoelectric sensor 61 directly receives the light from the light-emitting block 52. At this time, the fabric is pressed by the pressure plate 21 and the final part of the overlocking is performed by the pressure needle 22. When the overlocking is completed, the operator moves the pressure needle 22 and the pressure plate 21 upward by the first pedal 11 and the second pedal 12. During this process, when the pressure needle 22 moves upward but the pressure plate 21 has not moved upward, the controller 6 starts the drive motor 41, which drives the cutter 3 to move by rotating the lead screw, thereby cutting the thread. There is no need to manually use scissors to cut the thread, which reduces labor intensity and saves operation time, thereby improving the overlocking efficiency.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
