Description

Technical Field

[0001] This utility model relates to the field of garment processing machinery technology, specifically to a material setting mechanism for a bag opening machine. Background Technology

[0002] Currently, the bag opening machines widely used in the garment industry are equipped with a material setting device, a laser cutting device, a bag folding device, and a sewing device. Moreover, the bag folding device and the material setting device are set separately. The bag folding device is generally fixed above the material feeding area of ​​accessories such as bag eyebrow, bag fabric, or zipper, while the material setting device slides back and forth between the bag folding device, the laser cutting device, and the sewing device.

[0003] Chinese utility model patent CN222666241 U discloses a bag opening machine, which integrates a folding mechanism and a material setting mechanism into a bag opening forming device. It can fold the bag opening fabric immediately after it is cut, avoiding the offset and displacement of the bag opening fabric during transportation. In addition, it shortens the length of the worktable, shortens the moving distance of the bag opening fabric, improves the processing speed and efficiency, and also shortens the size of the bag opening machine, saving space.

[0004] However, during the bag manufacturing process, after the first piece of bag fabric is sewn together and the second piece is received, the first piece of bag fabric will sag downwards due to the weight of the fabric itself, causing wrinkles when it meets the second piece of bag fabric, resulting in a high product defect rate. Utility Model Content

[0005] The purpose of this invention is to provide a material setting mechanism for a bag opening machine, which solves the problem of wrinkles occurring when the first piece of bag fabric is sewn together with the second piece of bag fabric in the prior art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A material setting mechanism for a bag opening machine includes a small pressure frame and an outer pressure frame mounted on a connecting plate and raised and lowered in coordination. The small pressure frame is located above the outer pressure frame, and the outer pressure frame and the small pressure frame are respectively provided with bag opening processing windows. A bag clamping device is provided at the outer pressure frame.

[0008] The bag fabric clamping device consists of two clamping components. Each clamping component includes a mounting part and a clamping part. The two clamping components are located on the outer edge of the outer pressure frame. The two clamping parts are arranged opposite to each other. The two clamping parts clamp or release the bag fabric by moving closer or further apart from each other.

[0009] The clamping part includes a clamping arm and a drive component for driving the clamping arm to move.

[0010] The driving component is a cylinder, and the piston of the cylinder is connected to the clamping arm; the cylinders of the two clamping parts drive the two clamping arms to move closer or further apart to clamp or release the bag fabric.

[0011] The mounting part is a clamping structure set on the drive component. The clamping structure includes upper and lower clamps, which are clamped on the outer edge of the outer pressure frame.

[0012] The upper and lower clamping plates and the outer edge of the outer pressure frame are provided with corresponding mounting holes. Bolts or rivets are used to fix the bag cloth clamping device to the outer edge of the outer pressure frame through the mounting holes.

[0013] The advantages of this utility model are: 1. A bag-holding device is added to the outer pressure frame so that the first bag does not sag during movement and does not wrinkle when it overlaps with the second bag; 2. The mounting part of the bag-holding device is designed with two clamping pieces, which are easy to install on the outer edge of the outer pressure frame and easy to fix; 3. The clamping arm is driven by a cylinder, which is convenient to install, low in cost, and flexible. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent.

[0019] To simplify the description of this embodiment, some components that are well-known to those skilled in the art but are not related to the main content of this invention may be omitted in the accompanying drawings or description. Additionally, for ease of description, some components in the drawings may be omitted, enlarged, or reduced, but these do not represent the actual product dimensions or the complete structure.

[0020] A material setting mechanism for a bag opening machine, such as Figure 1As shown, it includes a small pressure frame 32 and an outer pressure frame 33 disposed on the connecting plate 31 and raised and lowered in coordination. The small pressure frame 32 is located above the outer pressure frame 33, and the outer pressure frame 33 and the small pressure frame 32 are respectively provided with bag opening processing windows 34; the above technical features are prior art.

[0021] A bag-holding device 6 is installed at position 33 of the outer pressure frame. For example... Figure 2 As shown, the bag fabric clamping device 6 consists of two clamping components. Each clamping component includes a mounting part 61 and a clamping part. The two clamping components are located on the outer edge of the outer pressure frame 33, and the two clamping parts are arranged opposite to each other. The two clamping parts clamp or release the bag fabric 64 by moving closer or further apart from each other. The clamping part includes a clamping arm 62 and a driving component 63 for driving the clamping arm 62.

[0022] Preferably, the driving component 63 is a cylinder, and the piston of the cylinder is connected to the clamping arm 62; the cylinders of the two clamping parts drive the two clamping arms 62 to move closer or further apart to clamp the bag cloth 64 or release the bag cloth 64.

[0023] After sewing the bag eyebrow and the first piece of bag fabric 64 is completed, as follows Figure 3 As shown, the cylinders of the two clamping parts drive the two clamping arms 62 to move closer together, clamping the outer end of the first pocket fabric 64. This prevents wrinkles from forming at the seam between the pocket flap and the first pocket fabric 64 due to the sagging of the first pocket fabric 64 during the movement towards the second pocket fabric 64. Consequently, no wrinkled defective products are produced when the first pocket fabric 64 overlaps with the second pocket fabric 64. When the first pocket fabric 64 moves above the second pocket fabric 64, the cylinders drive the two clamping arms 62 to move away and separate, releasing the first pocket fabric 64.

[0024] Preferably, without making major changes to the structure of the existing material feeding mechanism, the bag clamping device 6 is located on the outer edge of the outer pressure frame 33, such as... Figure 2 As shown, the mounting part 61 is a clamping structure provided on the driving component 63. The clamping structure includes two clamping pieces 611, which are clamped to the outer edge of the outer pressure frame 33.

[0025] The upper and lower clamping plates 611 and the outer edge of the outer pressure frame 33 are provided with corresponding mounting holes 612. Bolts or rivets are used to fix the clamping bag cloth device 6 to the outer edge of the outer pressure frame 33 through the mounting holes 612.

[0026] In the prior art, after the fabric is sewn with the bag flap and the first piece of bag fabric 64, a support is needed to hold the fabric down during the process of the material positioning device moving to receive the second piece of bag fabric 64. Otherwise, when the first piece of bag fabric 64 is attached to the fabric after the movement, it is easy for wrinkles to form, resulting in the bag opening not meeting the requirements. The function of the bag fabric clamping device 6 of this utility model is that, after the fabric is sewn with the bag flap and the first piece of bag fabric 64, during the process of the material positioning device moving to receive the second piece of bag fabric 64, the clamping arm 62 clamps the outer end of the first piece of bag fabric 64. In this way, the first piece of bag fabric 64 will not shift and wrinkle during the movement, and it will be very flat when attached to the second piece of bag fabric 64, significantly reducing the defect rate of the product, and at the same time, no support is needed.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made within the scope of the claims of this utility model should be considered within the technical scope of this utility model.
