DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] like Figure 1 As shown, the utility model provides a cutting device for sandal production, comprising a support frame 1 and a feeding port 2 opened on the support frame 1 for conveying leather materials.

[0023] like Figures 1 to 3 As shown, in this embodiment, a cylinder 3 is locked and fixed on the top of the support frame 1, and a limiting component 4 for positioning the leather material is provided in the feeding port 2;

[0024] The piston rod at the bottom of the cylinder 3 moves vertically through the top of the support frame 1 and is connected to the lifting frame 5, so that the lifting frame 5 can be driven to move vertically up and down in the support frame 1 by controlling the cylinder 3. An electric slide bar 6 is fixedly installed in the middle of the bottom end surface of the lifting frame 5. The electric slide bar 6 extends in the left and right directions and is used to adjust the position of the electric slide seat 11. A tensioning assembly is respectively provided at the front and rear ends of the bottom of the lifting frame 5 for pressing the leather material.

[0025] An electric slide seat 11 is slidably mounted on the electric slide bar 6, a motor 12 is locked and fixed on the electric slide seat 11, a cutting knife 13 for cutting leather material is fixed on the output shaft of the motor 12, and the leather is cut by driving the cutting knife 13 to rotate by the motor 12. A support plate 14 connected to the inner bottom of the support frame 1 is arranged below the cutting knife 13, and the support plate 14 is used to provide support for the leather material;

[0026] In this embodiment, the tensioning assembly includes a fixed cylinder 7 installed at the left and right ends of the bottom of the lifting frame 5, and a sliding frame 8 movably inserted into the fixed cylinder 7. The sliding frame 8 is connected to the bottom end surface of the lifting frame 5 through a spring 9, and a pressure roller 10 is rotatably installed at the bottom of the left and right opposite surfaces of the two sliding frames 8;

[0027] The bottom end surfaces of the sliding frame 8 and the cutting knife 13 are higher than the bottom end surface of the pressing roller 10, so that the pressing roller 10 can press and fix the leather.

[0028] In this embodiment, a strip groove 15 is formed on the top surface of the support plate 14, and the strip groove 15 is located vertically below the cutting blade 13 to prevent the cutting blade 13 from being damaged due to collision with the support plate 14;

[0029] In this embodiment, a cylinder 3 is provided at each of the left and right ends of the top of the support frame 1, and the bottom piston rods of the two cylinders 3 are respectively connected to the left and right ends of the top of the lifting frame 5, so that the lifting frame 5 can be driven to move vertically stably by the two cylinders 3;

[0030] During operation, the leather for producing the upper of the sandals is conveyed to the support frame 1 through the feeding port 2. When the cut leather is large, the unwinding frame and the winding frame of the leather are respectively arranged on the front and rear sides of the support frame 1, and the end of the leather passes through the feeding port 2.

[0031] When it is necessary to cut the leather, the lifting frame 5, the fixed cylinder 7, the movable frame 8 and the pressure roller 10 can be driven downward by controlling the air cylinder 3. The pressure roller 10 moves downward to apply pressure to the leather. The leather is supported by the support plate 14. The pressure exerted by the pressure roller 10 on the leather is located on both sides of the support plate 14, so that the leather is under pressure and is in a taut state. When the lifting frame 5 continues to move downward, the spring 9 is compressed by the pressure of the movable frame 8. The lifting frame 5 drives the cutting knife 13 to continue to move downward and contact the leather. Then the motor 12 is started to drive the cutting knife 13 to rotate and cut the leather. The electric slide 6 can be controlled to make the electric slide 11 move along the electric slide 6. The electric slide 11 drives the motor 12 and the cutting knife 13 to move to cut different parts of the leather. Then the cut leather is pulled out. The air cylinder 3 is controlled to drive the cutting knife 13 to move upward, and the leather is pulled again for further cutting.

[0032] like Figure 3 and Figure 4 As shown, in this embodiment, the limiting assembly 4 includes a guide roller 41 rotatably mounted in the feeding port 2, the guide roller 41 provides support for the leather, and improves the stability of the leather during transportation. Two limiting sleeves 42 are slidably mounted on the guide roller 41, and a bolt 43 is movably passed through each limiting sleeve 42. The bolt 43 passes through the outer surface of the limiting sleeve 42 and is closely attached to the outer end surface of the guide roller 41;

[0033] In this embodiment, a threaded hole is formed on the limit sleeve 42, and the inner side of the threaded hole cooperates with the bolt 43, and the limit sleeve 42 is pressed and fixed on the guide roller 41 through the bolt 43 and the threaded hole;

[0034] During use, when it is necessary to provide positioning for the leather, the bolt 43 can be turned to disengage the guide roller 41, and then the two limit sleeves 42 can be moved so that the two limit sleeves 42 are respectively attached to the left and right sides of the leather, and then the bolt 43 is turned in the opposite direction to fix the limit sleeves 42 on the guide roller 41. The two limit sleeves 42 are used to provide positioning for the leather, reduce the deviation and sliding of the leather, and improve the leather cutting effect.

[0035] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
