Description

Technical Field

[0001] This application relates to the technical field of sewing equipment, and in particular to an overlock sewing machine. Background Technology

[0002] Overlock sewing machines (also known as edging machines or overlock sewing machines) are sewing equipment specifically designed for processing the edges of fabrics. Their core function is to prevent fabric edges from fraying by cutting, covering, and sewing, while also improving sewing efficiency and aesthetics.

[0003] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN208857457U, which discloses an overlock sewing machine, including a frame with a mounting panel on the top. The top surface of the mounting panel is fixed with the overlock sewing machine body. A needle bar chamber is installed on the top of the overlock sewing machine body, and a presser foot lifting rod is installed at the bottom of the needle bar chamber. The bottom end of the presser foot lifting rod is connected to a presser foot. An oil dipstick is installed on the outer surface of the overlock sewing machine body. A pulley and an oil dipstick are installed on the side of the overlock sewing machine body. An oil window is installed on one side of the needle bar chamber, and the oil window is located on the top of the overlock sewing machine body. Several tension nuts are installed on the front panel of the overlock sewing machine body. Four needle bars are arranged in the needle bar chamber.

[0004] However, during continuous operation, the overlock sewing machine needs to constantly cut edges and trim threads, resulting in a buildup of small pieces of fabric and thread ends on the worktable. These impurities can easily negatively impact the overlock sewing process and create a dirty working environment, interfering with the user's work. Utility Model Content

[0005] In order to reduce the probability that impurities on the workbench surface will adversely affect the fabric overlocking process, this application provides an overlocking machine.

[0006] This application provides an overlock sewing machine, which adopts the following technical solution:

[0007] An overlock sewing machine includes a worktable and a machine body disposed on the worktable. The worktable is equipped with a cleaning device for cleaning impurities from its surface. The cleaning device includes:

[0008] The air cleaning tube is horizontally slidably mounted on the workbench and connected to the air source;

[0009] A collection box is set on a workbench and has a collection hole.

[0010] A moving mechanism, which is mounted on a workbench and is used to drive the movement of the cleaning airway.

[0011] By adopting the above technical solution, a cleaning air pipe is horizontally slidably installed on the workbench via a moving mechanism, and a collection box is then installed on the workbench. By moving the cleaning air pipe to blow air onto the surface of the workbench, impurities scattered on the surface of the workbench can be blown into the collection box for centralized collection and treatment, thereby completing the cleaning of impurities on the surface of the workbench and ensuring that the machine can perform normal overlock sewing work on the fabric.

[0012] Optionally, the moving mechanism includes:

[0013] A movable block is horizontally slidably mounted on a worktable, and the cleaning air pipe is mounted on the movable block;

[0014] A movable lead screw, which is rotatably mounted on the worktable and threadedly connected to a movable block;

[0015] A movable motor is mounted on the worktable and its output shaft is connected to a movable lead screw.

[0016] By adopting the above technical solution, the moving motor starts and drives the moving screw to rotate, the moving screw rotates and drives the moving block to move, and the moving block drives the cleaning air pipe to move. Thus, by controlling the moving motor, the position of the cleaning air pipe on the worktable is moved, so that the cleaning air pipe can blow air to clean various positions on the worktable.

[0017] Optionally, the moving block is provided with a sliding mechanism, and the cleaning air tube is horizontally slidably mounted on the moving block along a direction perpendicular to the moving direction of the moving block via the sliding mechanism. The sliding mechanism includes:

[0018] The slide rail has a horizontal sliding groove on the bottom of the moving block along a direction perpendicular to the moving direction of the moving block, and the slide rail is disposed on the bottom wall of the sliding groove;

[0019] A sliding block is slidably disposed on the slide rail along the length of the slide rail, and the cleaning air tube is disposed on the sliding block;

[0020] A limiting component is disposed on the sliding block and is used to fix and limit the position of the sliding block in the sliding groove.

[0021] By adopting the above technical solution, a slide rail is installed on the moving block, and a sliding block is slidably installed on the slide rail. By unlocking the limiting component, the sliding block can be moved along the slide rail to adjust the position of the cleaning air tube on the moving block. This realizes the movement of the cleaning air tube at any position on the workbench and expands the cleaning range of the cleaning air tube.

[0022] Optionally, the limiting component includes:

[0023] The limiting block has a horizontal moving groove on the side wall that contacts the inner side wall of the sliding groove, and the limiting block is slidably disposed on the moving groove.

[0024] A limiting spring is provided on the bottom wall of the sliding groove and connected to a limiting block. The limiting block is pressed against the inner side wall of the sliding groove under the action of the limiting spring.

[0025] A driving component, which is mounted on a sliding block and is used to drive the limiting block to move in compression of the limiting spring.

[0026] By adopting the above technical solution, when it is necessary to move the sliding block, the driving component is used to drive the limiting block to compress the limiting spring and move it, so that the limiting block is disengaged from the inner wall of the sliding groove, thereby releasing the limiting effect of the limiting block on the sliding block, and thus the sliding block can move freely. When the sliding block moves to the target position, the driving rod is used to move the limiting block back to its original position, and then the limiting block is pressed against the inner wall of the sliding groove under the action of the limiting spring, thereby limiting the sliding block in the sliding groove.

[0027] Optionally, the driving element includes:

[0028] A drive rod, which is vertically slidably mounted on a sliding block;

[0029] A driving block is disposed at the top of a driving rod. The top of the driving block has an inclined first guide surface, the height of the end of the first guide surface near the limiting spring being lower than the height of the end away from the limiting spring. An inclined second guide surface is disposed on the lower side wall of the limiting block, the height of the end of the second guide surface near the limiting spring being lower than the height of the end away from the limiting spring. When the driving block extends into the sliding groove so that the first guide surface and the second guide surface are in contact, the limiting block compresses the limiting spring and the whole is located in the sliding groove.

[0030] By adopting the above technical solution, when it is necessary to move the sliding block, the moving drive rod moves upward, which drives the driving block to move upward. After the driving block moves upward, the first guide surface on the driving block and the second guide surface on the limiting block come into contact. As a result, the limiting block will move along with the driving block and compress the limiting spring, causing the limiting block to disengage from the inner wall of the sliding groove. After the limiting block disengages from the inner wall of the sliding groove, the sliding block can move freely. After the sliding block moves to the target position, the moving drive rod moves downward, which drives the driving block to move downward until the driving block disengages from the limiting block. Then, the limiting block disengages from the inner wall of the sliding groove, thereby limiting the sliding block.

[0031] Optionally, the cleaning air tube includes a base, a tube body, and an air outlet. The base is mounted on a sliding block and is connected to an air source. The tube body is a flexible hose made of a flexible material. The air outlet is located at the end of the tube body away from the base. A fixing component is provided on the workbench, and the air outlet is fixed to the workbench through the fixing component.

[0032] By adopting the above technical solution, the cleaning tube is made of a flexible material, which allows the user to move the tube freely to blow air onto the workbench surface, greatly improving the convenience of using the cleaning tube. When the cleaning tube is not in use, it is fixed and stored on the workbench by a fixing component, which reduces the interference caused by the shaking of the cleaning tube to the workers and also protects the cleaning tube.

[0033] Optionally, the fixing component includes:

[0034] A fixed hook is provided on the workbench;

[0035] A fixed hanging ring is provided on the air outlet and is sleeved with a fixed hook.

[0036] By adopting the above technical solution, a fixed hook is installed on the workbench. When the cleaning air pipe is not needed, the fixed hanging ring on the air outlet of the cleaning air pipe can be moved and hung on the fixed hook, which is convenient, quick and efficient.

[0037] Optionally, the workbench is provided with guide plates, and two guide plates are provided, which are located on both sides of the collection box in the horizontal direction and connected to both ends of the collection hole.

[0038] By adopting the above technical solution, two guide plates are fixedly installed on the workbench. The two guide plates guide the impurities blown by the cleaning air pipe and guide the impurities into the collection box, thereby improving the collection efficiency of the collection box for impurities.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0040] 1. By horizontally sliding the cleaning air pipe on the workbench via a moving mechanism, and then installing a collection box on the workbench, the cleaning air pipe is moved to blow air onto the surface of the workbench, which blows the impurities scattered on the surface of the workbench into the collection box for centralized collection and treatment, thus completing the cleaning of impurities on the surface of the workbench and ensuring that the machine can perform normal overlock sewing work on the fabric.

[0041] 2. The moving motor starts and drives the moving screw to rotate. The rotation of the moving screw drives the moving block to move. The movement of the moving block drives the cleaning air pipe to move. Thus, by controlling the moving motor, the position of the cleaning air pipe on the worktable is moved, so that the cleaning air pipe can blow air to clean various positions on the worktable.

[0042] 3. By fixing two guide plates on the workbench, the two guide plates guide the impurities blown by the cleaning air pipe and guide the impurities into the collection box, thereby improving the collection efficiency of the collection box for impurities. Attached Figure Description

[0047] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0048] This application discloses an overlock sewing machine.

[0049] Reference Figure 1 The overlock sewing machine includes a worktable 11 and a machine body 12 disposed on the worktable 11. A cleaning device 2 is provided on the worktable 11 for cleaning impurities on the surface of the worktable 11.

[0050] Reference Figure 1 and Figure 2The cleaning device 2 includes a cleaning air pipe 21, a collection box 22, and a moving mechanism 23. The cleaning air pipe 21 is horizontally slidable on the worktable 11 via the moving mechanism 23 and is connected to an air source. The collection box 22 is fixedly installed on the worktable 11. A horizontal collection hole is opened on the side wall of the collection box 22 near the machine body 12, and the collection hole is connected to the inside of the collection box 22. Guide plates 13 are fixedly installed on the worktable 11 at both ends of the horizontal direction of the collection hole, and the ends of the two guide plates 13 that are close to each other are respectively connected to the two ends of the collection hole.

[0051] Reference Figure 1 and Figure 2 The moving mechanism 23 includes a moving block 24, a moving screw 25, and a moving motor 26. The moving block 24 is horizontally slidable on the worktable 11 along the length of the opening of the collection box 22. The moving screw 25 is rotatably mounted on the worktable 11 and is set in a horizontal position, and the moving screw 25 is threadedly connected to the moving block 24. The moving motor 26 is fixedly mounted on the worktable 11 and its output shaft is connected to the moving screw 25.

[0052] Reference Figure 2 The moving motor 26 starts, driving the moving lead screw 25 to rotate. The rotation of the moving lead screw 25 drives the moving block 24 to move, and the movement of the moving block 24 drives the cleaning air pipe 21 to move. Thus, by controlling the moving motor 26, the position of the cleaning air pipe 21 on the worktable 11 is moved, allowing the cleaning air pipe 21 to blow air to clean various locations on the worktable 11. After the cleaning air pipe 21 is ventilated, the impurities scattered on the surface of the worktable 11 are blown into the collection box 22 for centralized collection and treatment, thereby completing the cleaning of impurities on the surface of the worktable 11 and ensuring that the machine body 12 can perform normal overlock sewing work on the fabric.

[0053] Reference Figure 2 and Figure 3 A sliding mechanism 3 is provided on the movable block 24, through which the cleaning air tube 21 is horizontally slidably mounted on the movable block 24 in a direction perpendicular to the moving direction of the movable block 24. The sliding mechanism 3 includes a slide rail 31, a sliding block 32, and a limiting component 33. A horizontal sliding groove 34 is formed on the lower surface of the movable block 24 in a direction perpendicular to the moving direction of the movable block 24. The slide rail 31 is fixedly mounted on the bottom wall of the sliding groove 34. The sliding block 32 is slidably mounted on the slide rail 31 along the length of the slide rail 31.

[0054] Reference Figure 2 and Figure 3 The air duct 21 includes a base 27, a tube body 28, and an air outlet 29. The base 27 is fixedly mounted on the lower surface of the sliding block 32 and is in communication with the air source. The tube body 28 is mounted on the lower surface of the base 27 and is a flexible hose made of a flexible material. The air outlet 29 is fixedly mounted on the end of the tube body 28 away from the base 27.

[0055] Reference Figure 2 and Figure 3 A limiting component 33 is disposed on the sliding block 32 and is used to fix and limit the position of the sliding block 32 within the sliding groove 34. The limiting component 33 includes a limiting block 35, a limiting spring 36, and a driving member 37. A horizontal moving groove 38 is formed on the side wall of the sliding block 32 that contacts the inner side wall of the sliding groove 34, and the limiting block 35 is slidably mounted on the moving groove 38. The limiting spring 36 is fixedly mounted on the bottom wall of the moving groove 38 and connected to the limiting block 35, and the limiting block 35 is pressed against the inner side wall of the sliding groove 34 under the action of the limiting spring 36.

[0056] Reference Figure 2 and Figure 3 A driving component 37 is mounted on the sliding block 32 and is used to drive the limiting block 35 to compress the limiting spring 36. The driving component 37 includes a driving rod 41 and a driving block 42. The driving rod 41 is vertically slidably mounted on the bottom of the sliding block 32. The driving block 42 is fixedly mounted on the top of the driving rod 41. An inclined first guide surface 43 is provided at the top of the driving block 42, and the height of the end of the first guide surface 43 near the limiting spring 36 is lower than the height of the end away from the limiting spring 36. An inclined second guide surface 44 is provided on the lower side wall of the limiting block 35, and the height of the end of the second guide surface 44 near the limiting spring 36 is lower than the height of the end away from the limiting spring 36. When the driving block 42 extends into the sliding groove 34 so that the first guide surface 43 and the second guide surface 44 are in contact, the limiting block 35 compresses the limiting spring 36 and is entirely located within the moving groove 38.

[0057] Reference Figure 2 and Figure 3 When the sliding block 32 needs to be moved, the moving drive rod 41 moves upward, causing the driving block 42 to move upward. After the driving block 42 moves upward, the first guide surface 43 on the driving block 42 and the second guide surface 44 on the limiting block 35 come into contact. As a result, the limiting block 35 will move along with the driving block 42, compressing the limiting spring 36 and causing the limiting block 35 to disengage from the inner wall of the sliding groove 34. After the limiting block 35 disengages from the inner wall of the sliding groove 34, the sliding block 32 can move freely. After the sliding block 32 moves to the target position, the moving drive rod 41 moves downward, causing the driving block 42 to move downward until the driving block 42 disengages from the limiting block 35. Then, the limiting block 35 disengages from the inner wall of the sliding groove 34, thus limiting the sliding block 32.

[0058] Reference Figure 1 and Figure 2A fixing component 5 is provided on the workbench 11, and the air outlet 29 is connected and fixed to the workbench 11 through the fixing component 5. The fixing component 5 includes a fixing hook 51 and a fixing ring 52. The fixing hook 51 is fixedly installed on the workbench 11. The fixing ring 52 is fixedly installed on the outer wall of the air outlet 29 and is sleeved with the fixing hook 51. When the cleaning air pipe 21 is not needed, the fixing ring 52 on the air outlet 29 of the cleaning air pipe 21 can be moved and hung on the fixing hook 51, which is convenient, quick and efficient.

[0059] The working principle of this application embodiment is as follows:

[0060] The cleaning air pipe 21 is horizontally slidable and installed on the workbench 11, and the collection box 22 is installed on the workbench 11. By moving the cleaning air pipe 21 to blow air onto the surface of the workbench 11, the impurities scattered on the surface of the workbench 11 can be blown into the collection box 22 for centralized collection and treatment, thereby completing the cleaning of impurities on the surface of the workbench 11 and ensuring that the machine body 12 can perform normal overlock sewing work on the fabric.
