Description

Technical Field

[0001] This utility model relates to the field of bag opening machine technology, specifically to a bag opening machine slitting device with a fabric lifting device. 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: After the existing bag-opening machine laser-cuts the fabric, it is necessary to replace the laser-cut template with a bag fabric sewing template. During the template replacement process, in order to prevent the fabric from falling off when the template is pulled out, several columnar lifting devices that can move upward are set on the machine to lift the fabric. However, the lifting area of ​​the columnar lifting devices is small. When lifting small pieces of fabric, it is often difficult to obtain a good lifting effect due to its small contact area. This can easily cause the fabric to become skewed as the template is pulled, affecting the subsequent sewing accuracy of the bag fabric. At the same time, when fixing, the segmentation device must be fixed in the position of the lifting device on the machine and cannot be moved, which affects the processing speed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a bag-opening machine segmentation device with a fabric lifting device that can move and fix fabric and adapt to fabrics of different sizes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bag-opening machine slitting device with a fabric lifting device, comprising a back plate and a slitting device body fixedly disposed at the lower end of the front side of the back plate, wherein a slitting frame is detachably provided on the back plate, and a fabric lifting device extending to the lower front side of the slitting device body is also provided on one side of the slitting device body, wherein the fabric lifting device includes a fabric support plate slidably disposed below the slitting device body, and the fabric lifting device further includes a push-pull cylinder fixedly connected to one side of the slitting device body, wherein the end of the push-pull cylinder is fixedly connected to the edge of the fabric support plate.

[0006] A further improvement is that the support plate has several square slots integrally formed.

[0007] After adopting the above technical solution, the beneficial effects of this utility model are as follows: After the fabric bag is opened, the fabric lifting device set on one side of the slitting device body can fix the bag fabric placed on the template. During the opening process, the push-pull cylinder of the fabric lifting device is in the extended state, so that the supporting plate will not directly contact the fabric. After the opening is completed, the push-pull cylinder is pulled back to retract and drive the supporting plate to move, thereby inserting the supporting plate under the template with the bag fabric for lifting. Together with the separation device body, the bag fabric is clamped and fixed. Thus, when the template of the bag fabric is removed, the bag fabric can be clamped, fixed and lifted, and the bag fabric will not be pulled by the template and become skewed. At the same time, compared with the existing columnar structure lifting device, the supporting plate has a larger coverage area, thus it can adapt to smaller bag fabrics and has better adaptability. In addition, the fabric lifting device moves with the slitting device, so it does not need to be in a specific position and wait when fixing the fabric, thus improving the processing speed.

Detailed Implementation

[0010] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0011] See Figure 1-3 As shown, the technical solution adopted in this specific embodiment is: a bag-opening machine with a fabric lifting device for separating pieces, including a back plate 41 and a separating device body 42 fixedly disposed on the lower front side of the back plate 41. A separating frame 44 is detachably provided on the back plate 41. A fabric lifting device extending to the lower front side of the separating device body 42 is also provided on one side of the separating device body 42. The fabric lifting device includes a fabric support plate 430 slidably disposed below the separating device body 42. In use, the bag fabric is placed on the separating device body 42 of the separating device, and then a pocket is formed by laser cutting in conjunction with the pressing down of the separating frame provided on the back plate 41. The pocket fabric is then pulled open by the separating device body 42. After the pocket is opened, the fabric can be lifted by the separating device body 42. 2. The bag fabric lifting device on one side is used to fix the bag fabric placed on the template. During the opening process, the bag fabric lifting device support plate 430 is in a pulled-out state, so that the support plate 430 does not directly contact the bag fabric. After the opening is completed, the support plate 430 is pushed inward so that it moves along the lower surface of the segmentation device body 42, and then the support plate 430 is inserted under the template with the bag fabric for lifting. Together with the segmentation device body 42, the bag fabric is clamped and fixed. So when the template of the bag fabric is removed, the bag fabric can be clamped, fixed and lifted, and the bag fabric will not be pulled by the template and become skewed. At the same time, compared with the existing columnar structure lifting device, the support plate 430 has a larger coverage area, so it can be adapted to smaller bag fabrics and has better adaptability. The fabric lifting device also includes a push-pull cylinder 45 fixedly connected to one side of the sheet-splitting device body 42. The end of the push-pull cylinder 45 is fixedly connected to the edge of the fabric support plate 430, which is beneficial to directly drive the fabric support plate 430 to move through the push-pull cylinder 45, thereby eliminating the need to manually push the fabric support plate 430 to move to fix the bag fabric, and further improving automation. The support plate 430 has several square slots integrally formed. These square slots help to reduce the contact area when the template is pulled out, thereby reducing the frictional resistance when the template is pulled out. This makes the force required to pull out the template smaller, while ensuring the contact area with the bag fabric so that the bag fabric can be fully supported.

[0012] The working principle of this utility model is as follows: When in use, the bag fabric is placed on the body 42 of the slitting device. Then, a pocket is formed by laser cutting and pressing down on the slitting frame on the back plate 41. The pocket fabric is then pulled open by the body 42 of the slitting device. After the pocket is opened, the bag fabric placed on the template is fixed by a bag fabric lifting device located on one side of the body 42. During the opening process, the fabric lifting device's support plate 430 is in a pulled-out state, thus preventing direct contact with the template. After the bag fabric is opened, the support plate 430 is pushed inward so that it moves along the lower surface of the dividing device body 42. The support plate 430 is then inserted under the template with the bag fabric to lift it up. Together with the dividing device body 42, the bag fabric is clamped and fixed. When the template of the bag fabric is removed, the bag fabric can be clamped, fixed and lifted up, preventing the bag fabric from being pulled by the template and becoming skewed. At the same time, compared with the existing columnar lifting device, the support plate 430 has a larger coverage area, which can accommodate smaller bag fabrics and has better adaptability.
