Description

Technical Field

[0001] This utility model relates to the field of bag opening machine technology, specifically to a secondary pressing structure for a bag opening machine segmentation device that can be flipped up. Background Technology

[0002] A pocket opening machine is a professional sewing device used to cut and sew pocket openings on garments. Its main body is a large flat platform equipped with a servo drive system, a laser cutting system, a slitting device, and a sewing machine head. The servo drive system precisely moves the fabric clamping mechanism on the platform. The laser cutting system achieves non-contact cutting of the fabric, resulting in clean, burr-free cuts. The slitting device separates the laser-cut fabric into the shape of the pocket opening. Finally, the sewing machine head sews the opening onto the garment, thus shaping the pocket. The slitting device is typically fixedly installed on the pocket opening machine. On the large flatbed of the machine, directly below the laser cutting system, the servo drive system moves the fabric to the position of the slitting device. The slitting device then fixes the fabric, which is then cut by the laser cutting system. After cutting, the slitting device separates the two sides of the opening in the fabric and folds the fabric at the opening. Then, in conjunction with the servo drive system, the template is moved so that the cut fabric is sewn by the sewing machine head to form a fabric with pockets. This process is highly automated, has good slitting stability, and produces consistently high-quality fabric with pockets.

[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: the existing bag opening machines are equipped with a fabric pressing device on the slitting device for fixing the fabric. The fabric pressing device is pushed up and down by a cylinder. Due to the limited lifting space of the fabric pressing device, the gap between it and the body of the slitting device is small. When loading large pieces of fabric, the small operating space makes it difficult to observe whether the fabric is aligned with the scale on the template. Loading the fabric is difficult and inconvenient to operate, requiring a high level of experience. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a secondary pressing structure for a flip-up bag opening machine's slitting device that offers a large operating space and easy fabric loading.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a secondary pressing structure for a bag-opening machine slitting device that can be flipped up, including a pressing device that is slidably disposed on the front side of the rear plate of the slitting device and points downward toward the tray of the slitting device. The pressing device includes a lifting plate that is slidably disposed on the front side of the rear plate of the slitting device and a lower pressing plate that is movably engaged with the bottom surface of the lifting plate. A pressing cylinder is provided on the front edge of the lower pressing plate, and a pressing frame is provided at the lower end of the pressing cylinder.

[0006] A further improvement is that the lifting plate is also equipped with a rear plate front cylinder that is fixedly connected to the front side of the rear plate of the segmentation device.

[0007] A further improvement is that a lifting cylinder is movably engaged on the front of the lifting plate, and the bottom end of the lifting cylinder is movably engaged with the upper surface of the pressing plate.

[0008] A further improvement is that the side edge of the lower pressure plate is also provided with a pressure frame adjustment block for adjusting the front and rear position of the pressure frame, and the pressure frame adjustment block is locked with a fastening screw with a handle.

[0009] A further improvement is that a buffer spring with its bottom attached to the fabric pressing frame is also installed on the pressing plate.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are as follows: In the process of using this utility model, when it is necessary to put the fabric into the tray of the slitting device, the pressing cylinder can be pulled back first to raise the pressing frame, thereby creating a certain distance between the tray and the pressing frame, so that the fabric can be put in. When placing larger pieces of fabric, the lower pressing plate can be lifted up simultaneously, causing the lower pressing plate, together with the pressing cylinder and the pressing frame, to tilt upwards, thereby increasing the distance between the tray and the pressing frame. This provides more operating space when placing large pieces of fabric, making the operation more convenient and greatly reducing the difficulty of loading fabric. Attached Figure Description

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0014] See Figure 1-2As shown, the technical solution adopted in this specific embodiment is: a secondary pressing structure for a flip-up bag-opening machine slitting device, including a pressing device 425 slidably disposed on the front side of the rear plate 41 of the slitting device and pointing downwards toward the tray 421 of the slitting device. The pressing device 425 includes a lifting plate 13 slidably disposed on the front side of the rear plate 41 of the slitting device and a lower pressing plate 12 movably engaged with the bottom surface of the lifting plate 13. A pressing cylinder 16 is provided on the front edge of the lower pressing plate 12, and a pressing frame 15 is provided at the lower end of the pressing cylinder 16. In use, before loading the fabric, the pressing cylinder 16 is first retracted upwards, causing it to drive the lower pressing plate 12 and the pressing frame 15 to move upwards synchronously, so that a certain gap is created between the pressing frame 15 and the tray 421 of the slitting device. The template can be placed on the tray 421 of the slitting device, and the fabric can be taken out. The fabric is placed on the template through the gap between the pressing frame 15 and the tray 421. When placing a large piece of fabric, the lower pressing plate 12 can be lifted upwards at the same time, so that the lower pressing plate 12, together with the pressing cylinder 16 and the pressing frame 15, will move upwards, thereby increasing the distance between the tray 421 and the pressing frame 15. This provides more operating space when placing large pieces of fabric, making the operation more convenient and greatly reducing the difficulty of loading the fabric. After the fabric is placed, the lower pressing plate 12 and the pressing frame 15 can be restored. Then, the pressing cylinder 16 is driven to push the pressing frame 15 down and press it firmly on the fabric, thereby flattening and fixing the fabric. The lifting plate 13 is also equipped with a rear plate front cylinder 426 that is fixedly connected to the front side of the rear plate 41 of the slitting device. This is beneficial for controlling the lifting plate 13 to rise and fall through the rear plate front cylinder 426. In the case of limited space, the lifting plate 13 can be raised to obtain more operating space. At the same time, the lifting plate 13 can also drive the pressing frame 15 to fall, so that the pressing frame 15 can be initially attached to the fabric. This allows the fabric to be subjected to the dual pressure of the rear plate front cylinder 426 and the pressing cylinder 16, so as to obtain a better fixing and flattening effect. The lifting plate 13 has a lifting cylinder 11 that is movably engaged on the front. The bottom end of the lifting cylinder 11 is movably engaged with the upper surface of the lower pressing plate 12. This allows the entire lower pressing plate 12 and the fabric pressing frame 15 to be lifted obliquely by retracting the lifting cylinder 11 when not in use. This provides more operating space when the fabric is placed, and eliminates the need for manual lifting of the lower pressing plate 12, thus increasing the degree of automation. It also prevents the operation space from being too small when loading large pieces of fabric, which would affect the accuracy of placement. Furthermore, it makes placing the fabric simpler by expanding the operating space. The side edge of the pressing plate 12 is also provided with a pressing frame adjusting block 14 for adjusting the front and rear position of the pressing frame 15. The pressing frame adjusting block 14 is locked with a fastening screw with a handle, which makes it easy to adjust the pressing frame adjusting block 14 by loosening the fastening screw, thereby controlling the front and rear position of the pressing frame 15, so that the pressing frame 15 can be adapted to various sizes of fabric. The pressure plate 12 is also equipped with a buffer spring 17 whose bottom is attached to the pressure frame 15. This helps to absorb the reverse force after the pressure frame 15 descends rapidly, thereby preventing the pressure frame 15 from rebounding and bouncing, which would affect the pressure effect.

[0015] The working principle of this utility model is as follows: Before loading the fabric, the pressing cylinder 16 is first retracted upwards, causing the lower pressing plate 12 and the pressing frame 15 to move upwards synchronously. This creates a gap between the pressing frame 15 and the tray 421 of the separating device. The template can then be placed onto the tray 421 of the separating device, and the fabric can be removed. The fabric is then placed onto the template through the gap between the pressing frame 15 and the tray 421. When placing larger pieces of fabric, the lower pressing plate 12 can be lifted upwards simultaneously. This causes the lower pressing plate 12, along with the pressing cylinder 16 and the pressing frame 15, to tilt upwards, thereby increasing the distance between the tray 421 and the pressing frame 15. This provides more operating space when placing large pieces of fabric, making the operation more convenient and greatly reducing the difficulty of loading the fabric. After the fabric is placed, the lower pressing plate 12 and the pressing frame 15 can be restored. Then, the pressing cylinder 16 is driven to push the pressing frame 15 downwards and press it firmly onto the fabric, thereby flattening and fixing the fabric.
