Description

Technical Field

[0001] This utility model relates to the field of blanket processing technology, and more specifically to a pressing device for blanket edge locking. Background Technology

[0002] Blankets are a common type of bedding, providing warmth. They are typically thinner than quilts and are mostly made from animal or synthetic fibers, though blends are also used. During production, blankets are usually edge-locked to ensure a strong edge, prevent fraying and wear, and extend their lifespan. This is done using an overlock machine to ensure neat, secure edges. Additionally, a pressing device (such as a presser foot) is often used to tighten the edges, improving the quality of the overlock process. However, presser feet have a limited lifespan; wear or deformation can lead to uneven stitching or frayed edges, requiring replacement. Since presser feet are usually bolted in place, replacement requires tools (such as a wrench) to remove the old presser foot and install a new one, a cumbersome process that doesn't allow for replacement without tools. This aspect needs improvement. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pressing device for blanket edge locking, so as to solve the problems existing in the background art.

[0020] like Figure 1-5As shown, a pressing device for overlocking blankets includes an overlocking worktable 1, an overlocking machine 2 fixedly mounted on the top of the overlocking worktable 1, an overlocking needle 21 fixedly mounted on the overlocking end of the overlocking machine 2, a fixed box 4 fixedly mounted on one side below the overlocking machine 2, a limiting cover 5 provided below the fixed box 4, a presser foot 3 overlapping the bottom of the limiting cover 5, a through groove 31 opened in the middle of one side of the presser foot 3, the overlocking needle 21 located inside the through groove 31, an assembly block 32 fixedly connected to one side of the top of the presser foot 3, the assembly block 32 and the presser foot 3 being integrally formed, the outer wall of the assembly block 32 movably fitting into the inside of the limiting cover 5, connecting brackets 58 overlapping on both sides of the limiting cover 5, and positioning rods 59 movably fitting on both sides of the limiting cover 5, the number of positioning rods 59 being two, one of the two positioning rods 59 The end of the positioning rod 59 is inserted into the interior of both sides of the assembly block 32. The other end of the positioning rod 59 is fixedly connected to one side of the connecting frame 58. The top of the limiting cover 5 is fixedly installed with a protective cover 51. The interior of the protective cover 51 is provided with a bidirectional lead screw 55. The outer wall of the bidirectional lead screw 55 is symmetrically threaded with two push plates 56. The outer wall of the push plates 56 is slidably connected to the interior of the protective cover 51. The sides of the two push plates 56 are fixedly connected with two push rods 57. One end of the push rod 57 extends to the outside of the protective cover 51 and is fixedly connected to the top of one side of the connecting frame 58. A micro motor 52 is fixedly installed on one side of the inner wall of the protective cover 51. The output end of the micro motor 52 is fixedly installed on one end of the bidirectional lead screw 55. The other end of the bidirectional lead screw 55 is rotatably installed on the other side of the inner wall of the protective cover 51 through a bearing.

[0021] In this embodiment, by inserting one end of the two positioning rods 59 into the interior of both sides of the assembly block 32 through the limiting cover 5, the assembly block 32 can be fixed inside the limiting cover 5, and the presser foot 3 can be fixed below the limiting cover 5. If the presser foot 3 needs to be disassembled, the push rod 57, the connecting frame 58 and the positioning rod 59 can be moved by the cooperation of the micro motor 52 and the bidirectional lead screw 55, so that one end of the two positioning rods 59 can be moved out from the interior of both sides of the assembly block 32. At this time, the assembly block 32 can be moved out from the interior of the limiting cover 5, and the presser foot 3 can be disassembled. Example

[0022] like Figure 1-5 As shown, a geared motor 41 is fixedly installed on the top of the inner wall of the fixed box 4. A drive screw 42 is fixedly installed on the output end of the geared motor 41. The bottom end of the drive screw 42 is rotatably installed on the bottom of the inner wall of the fixed box 4 through a bearing. A pressure plate 43 is provided on the upper part of the inside of the fixed box 4. The internal thread of the pressure plate 43 is connected to the outer wall of the drive screw 42. Pressure rods 44 are fixedly connected to the four corners of the bottom of the pressure plate 43. There are four pressure rods 44. The bottom ends of the four pressure rods 44 penetrate the bottom of the fixed box 4 and are fixedly connected to the four corners of the top of the limit cover 5.

[0023] In this embodiment, the cooperation of the geared motor 41 and the drive screw 42 facilitates the movement of the pressure plate 43 inside the fixed box 4. The pressure plate 43, through the four pressure rods 44, drives the limiting cover 5, the assembly block 32 and the presser foot 3 to move downward, so that the presser foot 3 presses down on the edge of the blanket, which facilitates the pressing operation of the blanket edge. The pressing operation can ensure the firmness of the stitching of the blanket edge and improve the edge locking effect. The geared motor 41 and the micro motor 52 are both equipped with self-locking components. The fixed box 4 and the protective cover 51 are both equipped with power supplies, which can supply power to the geared motor 41 or the micro motor 52.

[0024] In summary, as Figure 1-5 As shown, this pressing device for blanket edge locking, when the edge locking needle 21 of the edge locking machine 2 is used to sew and lock the edge of the blanket, can drive the drive screw 42 to rotate through the output end of the geared motor 41. The drive screw 42 drives the pressure rod 44 to move through the pressure plate 43. The bottom end of the pressure rod 44 drives the limit cover 5, the assembly block 32 and the pressure foot 3 to move downward, so that the pressure foot 3 presses down on the edge of the blanket, which is convenient for pressing the edge of the blanket. The output end of the geared motor 41 rotates in the opposite direction, which is convenient for driving the pressure foot 3 to move upward, thereby releasing the pressing operation of the pressure foot 3 on the blanket.

[0025] When the presser foot 3 needs to be replaced, the bidirectional lead screw 55 is driven to rotate by the micro motor 52. The bidirectional lead screw 55 drives the two push plates 56 to move relative to each other inside the protective cover 51. At the same time, the two push plates 56 drive one end of the two positioning rods 59 to move out from the inside of the two sides of the assembly block 32 through the push rod 57 and the connecting bracket 58. At this time, the assembly block 32 can be moved out from the inside of the limiting cover 5, and the presser foot 3 can be disassembled. During installation, the assembly block 32 at the top of the presser foot 3 is placed inside the limiting cover 5. At this time, the bidirectional lead screw 55 is driven to rotate in the opposite direction by the micro motor 52, and one end of the two positioning rods 59 is inserted into the inside of the two sides of the assembly block 32 in the same way. The presser foot 3 can then be fixedly installed under the limiting cover 5, thereby completing the replacement of the presser foot 3.
