Description
Technical Field
[0001] This utility model relates to the field of textile machinery technology, specifically to a secondary pressing structure for an upward-turning bag opening machine. 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. 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
[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a secondary pressing structure for an upward-turning bag opening machine that offers a large operating space and reduces the difficulty of loading fabric.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a secondary pressing structure for an upward-turning bag opening machine, comprising a pressing device disposed on the front side of the rear plate of the slitting device and pointing downward toward the tray of the slitting device, the pressing device comprising a guide rail disposed on the rear plate of the slitting device and a lower slide plate slidably disposed on the guide rail, the bottom of the lower slide plate being movably engaged with a lifting plate by a locking structure, a secondary pressing cylinder being fixedly disposed on the bottom surface of the front side of the lifting plate, the bottom end of the secondary pressing cylinder being provided with a pressing frame, the pressing device further comprising a lifting device fixedly disposed on the rear plate of the slitting device, the top of the lifting device being fixedly connected to the top back of the lower slide plate.
[0005] A further improvement is that the bottom of the sliding plate is also provided with an L-shaped support frame that can fit against the bottom surface of the lifting plate.
[0006] A further improvement is that the engaging structure includes a rotating shaft integrally formed on one side of the lifting plate and a rolling bearing sleeved on the outer wall of the end of the rotating shaft. The engaging structure also includes an insertion hole integrally formed on the bottom of the lower slide plate. The rotating shaft is inserted into the insertion hole and is engaged with the insertion hole through the rolling bearing.
[0007] A further improvement is that a spring is also fixedly installed on the lifting frame.
[0008] A further improvement is that a fixing device is provided between the rear plate and the lifting plate of the segmentation device.
[0009] A further improvement is that the fixing device includes a recessed groove integrally formed on the rear plate of the segmentation device and a movable block detachably installed on the side of the lifting plate near the rear plate. The lower end of the recessed groove is integrally formed with a lifting step, and a rolling wheel with its outer side abutting the surface of the lifting step is movably engaged inside the movable block.
[0010] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When using this utility model, when it is necessary to put the fabric into the tray of the slitting device, the lifting device can be pulled back first, so that the lower slide can drive the lifting plate and the pressure frame to rise, thereby creating a certain distance between the tray and the pressure frame. This allows the fabric to be placed on the tray. When placing larger fabrics, after raising the pressure frame, the lifting plate can also be raised upwards, causing the lifting plate to rotate upwards along the pivot axis, thereby creating a certain angle of upward movement. This increases the distance between the tray and the pressure frame, providing more operating space when placing large pieces of fabric, making the operation more convenient, and greatly reducing the difficulty of loading fabrics.

Detailed Implementation
[0013] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0014] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a secondary pressing structure for an upward-turning bag opening machine, including a pressing device 3 disposed on the front side of the rear plate 2 of the slitting device and pointing downward toward the tray 1 of the slitting device. The pressing device 3 includes a guide rail 31 disposed on the rear plate 2 of the slitting device and a sliding plate 32 slidably disposed on the guide rail 31. The bottom of the sliding plate 32 is movably engaged with a lifting plate 34 through a locking structure. A secondary pressing cylinder 343 is fixedly disposed on the bottom surface of the front side of the lifting plate 34. A pressing frame 35 is disposed at the bottom end of the secondary pressing cylinder 343. The pressing device 3 also includes a lifting device fixedly disposed on the rear plate 2 of the slitting device. 33. The top of the lifting device 33 is fixedly connected to the top back of the lower slide plate 32. The engaging structure includes a rotating shaft 341 integrally formed on one side of the lifting plate 34 and a rolling bearing 342 sleeved on the outer wall of the end of the rotating shaft 341. The engaging structure also includes an insertion hole 321 integrally formed on the bottom of the lower slide plate 32. The rotating shaft 341 is inserted into the insertion hole 321 and is movably engaged with the insertion hole 321 through the rolling bearing 342. The insertion hole 321 is a blind hole, and its inner diameter is interference-fitted with the outer ring of the rolling bearing 342. The end of the rotating shaft 341 is interference-fitted with the inner ring of the rolling bearing 342, thereby enabling the lifting plate 34 to rotate around the rotating shaft 341. The axis rotates smoothly. During use, when the fabric needs to be placed onto the tray 1 of the slitting device, the lifting device 33 can be pulled back first. The lifting device 33 can be a pneumatic cylinder or a hydraulic cylinder. This causes the lower slide plate 32 to be lifted by the lifting device 33, simultaneously lifting the lifting plate 34, the secondary pressing cylinder 343, and the pressure frame 35. This creates a certain distance between the tray 1 and the pressure frame 35, allowing the fabric to be placed onto the tray 1. When placing larger fabrics, after raising the pressure frame 35, the lifting plate 34 can also be manually raised. The operator can manually pull the lifting plate 34 upwards. This causes the tray to rotate upward around the pivot 341, resulting in an upward tilt at a certain angle. This increases the distance between the tray 1 and the pressure frame 35, providing more operating space when placing large pieces of fabric. This makes the operation more convenient and greatly reduces the difficulty of loading the fabric. After the fabric is placed, the lifting device 33 can drive the lower slide plate 32, the lifting plate 34, and the pressure frame 35 to descend and press them onto the fabric. Then, the secondary pressing cylinder 343 is driven to push the pressure frame 35 downward and press it firmly onto the fabric. This fully flattens and fixes the fabric, allowing subsequent operations to be performed by the bag opening machine. The bottom of the sliding plate 32 is also provided with an L-shaped support frame 36 that can fit against the bottom surface of the lifting plate 34. This is beneficial for supporting the lifting plate 34 when the pressure frame 35 is lifted, so that it can be kept horizontal and prevented from tilting downwards. No manual support is required, making it more convenient to use.
[0015] A fixing device 37 is also provided between the rear plate 2 of the segmentation device and the lifting plate 34. The fixing device 37 includes a recessed groove 371 integrally formed on the rear plate 2 of the segmentation device and a movable block 373 detachably installed on the side of the lifting plate 34 near the rear plate 2. The lower end of the recessed groove 371 is integrally formed with a lifting step 372. The movable block 373 is movably engaged with a rolling wheel 374 whose outer side is attached to the surface of the lifting step 372. During use, when the sliding plate 32 drives the lifting plate 34 to rise to a certain degree, the movable block 373 drives the rolling wheel 374 to move away from the lifting step 372 and enter the recessed groove 371. When the pressure frame 35 stops pressing the fabric after entering the groove 371, the roller 374 leaves the surface of the lifting step 372, creating a gap between it and the groove 371. At this point, the lifting plate 34 can be raised, allowing it to change angle. When it is necessary to press the fabric, the sliding plate 32 is lowered, causing the roller 374 to move back down to the surface of the lifting step 372. This eliminates the space for the roller 374 to move, thus limiting the lifting plate 34 and preventing it from being raised. This improves the stability of pressing the fabric and prevents abnormal lifting from affecting the pressing effect. A spring is also fixed on the lifting frame 36, which is beneficial to automatically lift the lifting plate 34 after the lower slide plate 32 rises and the rolling wheel 374 moves into the recessed groove 371. This allows for a certain lifting angle without manual pushing, and reduces the resistance when manually lifting.
[0016] The working principle of this utility model is as follows: When using this utility model, if it is necessary to place the fabric onto the tray 1 of the separating device, the lifting device 33 can be pulled back first. The lifting device 33 can be a cylinder, a hydraulic cylinder, or a motor lifting structure. At this time, the lower slide plate 32 can be lifted by the lifting device 33, and simultaneously the lifting plate 34, the secondary pressing cylinder 343, and the pressure frame 35 can be lifted, thereby creating a certain distance between the tray 1 and the pressure frame 35. This allows the fabric to be placed onto the tray 1. When placing larger fabrics, after raising the pressure frame 35, the lifting plate 34 can also be raised upwards, allowing the lifting plate to... 34 rotates upward along the pivot 341, thereby increasing the distance between the tray 1 and the pressure frame 35. 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 lifting device 33 can drive the lower slide plate 32, the lifting plate 34, and the pressure frame 35 to descend and press them onto the fabric. Then, the secondary pressing cylinder 343 is driven to push the pressure frame 35 down and press it firmly onto the fabric, thereby fully flattening and fixing the fabric, and allowing subsequent operations to be performed by the bag opening machine.
