[0022] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined arbitrarily with each other.

[0023] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 Shown in the embodiments of the present invention, a synthetic leather cutting device is disclosed in this embodiment, which includes a cutting table 1, a control arm 2 and a laser cutting part 3. The control arm 2 includes two support frames 21 respectively arranged on the cutting table 1. A walking arm 22 is vertically arranged between the two support frames 21, and both ends of the walking arm are slidably connected to the corresponding support frames 21. A hydraulic cylinder 23 is fixedly connected to the middle position at the bottom of the walking arm 22, a piston end of the hydraulic cylinder 23 is fixedly connected to a mounting frame 24, and the laser cutting part 3 is arranged on the mounting frame 24.

[0024] In this embodiment, a walking motor structure (not shown in the figure) is provided between the walking arm 22 and the support frame 21, so that the walking arm 22 can slide along the length direction and the width direction of the support frame 21. The laser cutting part 3 is composed of a universal control head and a cutting head, so that the laser cutting part 3 can be adapted to the processing of products with different shapes. This is the prior art and will not be elaborated here.

[0025] As Figure 2 、 Figure 3 Shown, a support shaft 4 is vertically rotatably connected to the mounting frame 24. The support shaft 4 is located behind the laser cutting part 3, and the mounting frame 24 can drive the support shaft 4 and the laser cutting part 3 to move vertically synchronously. Two receiving rods 5 are horizontally fixedly connected to the support shaft 4. The two receiving rods 5 are vertically distributed, and a suction cup assembly 6 is respectively arranged on each receiving rod 5.

[0026] As Figure 1 、 Figure 2 Shown, the position of the suction cup assembly 6 is set as: when the laser cutting part 3 completes the cutting operation and moves to the next cutting position, one of the suction cup assemblies 6 is located above the finished leather material that has been cut. A control member 7 for controlling the reciprocating rotation of the support shaft 4 is arranged between the two support frames 21, so that the two suction cup assemblies 6 are alternately located above the finished leather material, so that when the mounting frame 24 drives components such as the support shaft 4 to move vertically, the two suction cup assemblies 6 can alternately extract the finished leather material.

[0027] After the laser cutting unit 3 completes the cutting operation, the walking arm 22 drives components such as the mounting frame 24 to move synchronously until the laser cutting unit 3 reaches the next cutting position. At this time, one of the suction cup assemblies 6 is located above the finished leather material that has been cut. Subsequently, the hydraulic cylinder 23 controls the mounting frame 24 to drive components such as the support shaft 4 to move downward until the laser cutting head reaches the cutting position. At this time, the suction cup assembly 6 abuts against the finished leather material, and the suction cup assembly 6 sucks the finished leather material under the action of negative pressure. After the laser cutting unit 3 finishes cutting again, the hydraulic cylinder 23 controls the mounting frame 24 to drive components such as the support shaft 4 to move upward. At this time, the suction cup assembly 6 extracts the finished leather material.

[0028] During the process of the laser cutting unit 3 moving to the next cutting position again, the support shaft 4 rotates, and the suction cup assembly 6 rotates to the side. Another suction cup assembly 6 is located above the finished leather material that has been cut. The staff only needs to remove the finished leather material adsorbed by the suction cup assembly 6 to complete the collection operation of the finished leather material. By repeating this process, the automatic extraction of the finished leather material during the synthetic leather cutting process can be achieved, reducing the burden on the staff and improving the operation efficiency.

[0029] As Figure 1 、 Figure 2 shown, the control member 7 includes two support bars 71 horizontally fixed to the corresponding support frames 21 respectively. A plurality of control racks 72 are horizontally arranged on the opposite sides of the two support bars 71, and the plurality of control racks 72 on the two support bars 71 are arranged alternately. At the same time, a control gear 73 is fixedly sleeved on the support shaft 4, and the control gear 73 can mesh with any one of the control racks 72.

[0030] As Figure 1 、 Figure 2 shown, when the control rack 72 separates from the corresponding control rack 72 on one of the support frames 21, the control rack 72 just meshes with the corresponding control rack 72 on the other support bar 71, so that the control gear 73 can rotate reciprocally under the action of the plurality of control racks 72. This design enables the support shaft 4 to automatically rotate reciprocally during the movement of the walking arm 22, which can not only improve the linkage cooperation effect between components but also improve the resource utilization efficiency.

[0031] As Figure 1 、 Figure 2 shown, the control rack 72 is set such that during the process of the control gear 73 meshing with and separating from the control rack 72, the support shaft 4 rotates 90°, that is, it rotates 90° during the extraction process of the finished leather material, so that the finished leather material can just move to both sides of the cutting position, facilitating the staff to collect the finished leather material on both sides of the cutting table 1.

[0032] As Figure 3As shown, each suction cup assembly 6 respectively includes a vacuum generator 61 and a pneumatic suction cup 62. The vacuum generator 61 is connected to the pneumatic suction cup 62 and is used to make the pneumatic suction cup 62 form a negative pressure. At the same time, a push button switch 63 is respectively connected to each vacuum generator 61, and the push button switch 63 is used to control the opening and closing of the corresponding vacuum generator 61.

[0033] As Figure 3 、 Figure 4 shown, a plurality of control blocks 8 are respectively arranged on the opposite sides of the two support bars 71, and the plurality of control blocks 8 are arranged in one-to-one correspondence with the plurality of control racks 72. At the same time, when the support shaft 4 rotates 90°, the push button switch 63 can abut against the corresponding control block 8. At this time, the control block 8 touches the contact button of the push button switch 63 to close the corresponding vacuum generator 61.

[0034] This design enables the negative pressure between the finished leather material and the corresponding pneumatic suction cup 62 to disappear after the finished leather material moves 90°. The finished leather material can automatically fall on both sides of the cutting table 1, facilitating the staff to collect the finished leather material. Moreover, this design can realize the automatic opening and closing control of the vacuum generator 61 without consuming an additional power source, thereby improving the resource utilization efficiency.

[0035] As Figure 1 、 Figure 5 shown, guide frames 9 are respectively vertically slidably connected to both sides of the cutting table 1. Support seats 10 are respectively horizontally slidably connected to the opposite sides of the two guide frames 9, and the sliding direction of the support seats 10 is perpendicular to the advancing direction of the laser cutting part 3. The two support seats 10 are connected by a pair of horizontally and parallel pressing plates 11, and the laser cutting part 3 can be located between the pair of pressing plates 11. A driving member 12 is arranged on the cutting table 1, and the driving member 12 is used to control the two guide frames 9 to move downward synchronously and make the pair of pressing plates 11 jointly press the synthetic leather material against the cutting table 1.

[0036] When cutting the synthetic leather material, the positions of the two pressing plates 11 can be adjusted, and the synthetic leather material can be pressed against the cutting table 1 by the two pressing plates 11, reducing the risk of the synthetic leather material shifting and also reducing the risk of the synthetic leather material moving upward synchronously when the pneumatic suction cup 62 extracts the finished leather material, ensuring the cutting accuracy.

[0037] As Figure 1 、 Figure 5 shown, the driving member 12 includes two groups of driving cylinders 121. The two groups of driving cylinders 121 are symmetrically arranged on both sides of the cutting table 1. The piston ends of each group of driving cylinders 121 are respectively fixedly connected to the corresponding guide frames 9, so that the two guide frames 9 can move vertically synchronously smoothly.

[0038] As Figure 1 、 Figure 5As shown, elastic protective layers 13 are fixedly connected to the bottoms of two pressing plates 11 respectively. In this embodiment, the protective layer 13 is made of an elastic material such as latex or silica gel to reduce the risk of the pressing plate 11 scratching the synthetic leather material, thereby ensuring product quality.
