DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] The following will further elaborate on the present utility model in conjunction with the attached Figures 1-5 , for a more detailed description.
[0028] A leather cutting machine for rugby production, referring to Figures 1-5 , including a workbench 1, a die 2 and a flattening member 4.
[0029] The workbench 1 is arranged horizontally, and a bracket 11 is fixedly installed on the upper end surface of the workbench 1. The bracket 11 in this embodiment is set as an inverted L shape. A cylinder 12 is fixedly installed on the bracket 11. The output shaft of the cylinder 12 is arranged vertically and is located directly above the workbench 1. A mounting plate 13 is fixedly connected to the output shaft of the cylinder 12.
[0030] The die 2 is installed at one end of the mounting plate 13 close to the workbench 1, and the side of the die 2 with a cutting edge faces the upper end surface of the workbench 1. A connecting member 3 is arranged between the die 2 and the mounting plate 13. The die 2 can be detachably connected to the mounting plate 13 through the connecting member 3 so as to replace dies 2 of different models according to actual needs.
[0031] The flattening member 4 is also installed at one end of the mounting plate 13 close to the workbench 1. Before the die 2 cuts the leather on the workbench 1, the flattening member 4 can flatten the part of the die 2 facing the leather and its surrounding parts. Therefore, the part of the leather cut by the die 2 will not bulge or fold, so that the shape of the leather cut by the die 2 will be the same as the shape of the die 2, and thus the produced rugby can meet the production standards, improving the qualified rate of rugby production.
[0032] Among them, the connecting member 3 includes a clamping block 31 and a driving member 32.
[0033] In this embodiment, two clamping blocks 31 are provided. The two clamping blocks 31 are arranged opposite to each other along the length direction of the die 2 and are both slidably connected to the bottom surface of the mounting plate 13. The driving member 32 is also installed on the bottom surface of the mounting plate 13, and the driving member 32 is used to drive the two sliders to move in the direction of approaching or separating from each other. When installing the die 2, place the die 2 between the two clamping blocks 31, and then drive the two clamping blocks to move in the direction of approaching each other through the driving member 32 until the two clamping blocks respectively abut against the side walls of the die 2, thereby realizing the installation of the die 2; on the contrary, driving the two clamping blocks 31 to move in the direction of separating from each other through the driving member 32 can realize the disassembly of the die 2.
[0034] In order to further improve the connection stability between the die 2 and the clamping block 31, limiting grooves 311 are opened on the opposite end faces of the two clamping blocks 31. The tips on both sides of the die 2 are respectively located in the limiting grooves 311 of the two clamping blocks 31. The setting of the limiting grooves 311 further restricts the lateral movement of the die 2, thereby further improving the stability of the die 2.
[0035] The driving member 32 includes a bidirectional lead screw 321 and a sliding nut 322.
[0036] A sliding groove 131 is formed in the lower end face of the mounting plate 13. The bidirectional lead screw 321 is located in the sliding groove 131. Both ends of the bidirectional lead screw 321 are rotatably connected to the groove walls of the sliding groove 131. Two sliding nuts 322 are provided. The two sliding nuts 322 are oppositely arranged on both sides of the middle of the bidirectional lead screw 321. The two sliding nuts 322 correspond to the two clamping blocks 31 one by one, and the two sliding nuts 322 are in sliding contact with the groove walls of the sliding groove. The clamping block 31 is fixedly connected to the lower end face of the sliding nut 322. One end of the bidirectional lead screw 321 extends to the outside of the sliding groove 131 and is fixedly connected with a rotating handle 323.
[0037] When it is necessary to drive the two clamping blocks 31 to move in the directions away from or close to each other, rotate the rotating handle 323 forward to drive the two sliding nuts 322 to move in the direction close to each other, so as to drive the two clamping blocks 31 to move in the direction close to each other. On the contrary, rotate the rotating handle 323 in the reverse direction, and the two clamping blocks 31 can be driven to move in the directions away from each other.
[0038] In addition, a positioning member 33 is further provided between the rotating handle 323 and the mounting plate 13. The positioning member 33 includes a rotating disc 331 and a plug pin 332.
[0039] The rotating disc 331 is fixedly installed coaxially at one end of the bidirectional lead screw 321 located outside. The rotating handle 323 is fixedly installed on the rotating disc 331. A first plug pin hole 3311 for the plug pin 332 to pass through is formed in the rotating disc 331. A plurality of second plug pin holes 132 for the plug pin 332 to be inserted into are formed in the side wall of the mounting plate 13. The plurality of second plug pin holes 132 are evenly spaced around the axis of the rotating disc 331. The first plug pin hole 3311 is communicated with one of the second plug pin holes 132. When the two clamping blocks 31 are both in tight contact with the mold 2, the rotating disc 331 cannot rotate any more. At this time, insert the plug pin 332 through the first plug pin hole 3311 and into the second plug pin hole 132. Therefore, the rotating disc 331 and the bidirectional lead screw 321 cannot rotate back, and the two clamping blocks 31 can always be in a state of being in tight contact with the mold 2, thereby further improving the connection stability between the mold 2 and the clamping blocks 31, and further improving the working stability of the equipment.
[0040] Finally, the flattening member 4 in this embodiment includes a hinged rod 41, a connecting rod 42 and a flattening rod 43.
[0041] There are two articulated rods 41, which are arranged on both sides of the mold 2 relative to each other along the width direction of the mold 2, and are both articulated to the lower end surface of the mounting plate 13. An articulated spring 44 is arranged between the articulated rod 41 and the mounting plate 13. There are also two connecting rods 42, and the two connecting rods 42 correspond to the two articulated rods 41 one by one. One end of the connecting rod 42 is fixedly connected to the articulated rod 41. There are also two flattening rods 43, and the two flattening rods 43 correspond to the two connecting rods 42 one by one. The flattening rod 43 is fixedly connected to the other end of the connecting rod 42, and the peripheral wall of the flattening rod 43 abuts against the leather on the workbench 1. The flattening rod 43 is closer to the workbench 1 than the mold 2.
[0042] When the cylinder 12 is started, the cylinder 12 moves downward, and at the same time drives the entire mounting plate 13 to move downward. The flattening rod will first abut against the leather on the workbench 1. As the mounting plate 13 continues to move downward, the two connecting rods 42 will rotate in a direction away from each other, thereby driving the flattening rods 43 to move in a direction away from each other. The flattening rods 43 are always in contact with the leather on the workbench 1 during the movement. Therefore, the leather between the two flattening rods 43 will be flattened. Then, as the cylinder 12 continues to move, the mold 2 will cut the leather between the two flattening rods 43, so that the shape of the cut leather is the same as the shape of the mold 2; when the cutting is completed, the cylinder 12 is started to move upward. Due to the setting of the articulated spring 44, the two connecting rods 42 rotate in a direction close to each other, thereby driving the two flattening rods 43 to move in a direction close to each other, so that the flattening rods 43 return to their original state for flattening the leather next time.
[0043] In order to avoid the phenomenon of jamming when the connecting rod 42 rotates as much as possible, the two connecting rods 42 are arranged obliquely in a direction away from each other, so that when the flattening rod 43 contacts the leather, the two connecting rods 42 will only rotate in a direction away from each other, and the situation where the two flattening rods 43 move in a direction close to each other and abut against and squeeze each other is avoided, thereby ensuring the smooth operation of the equipment.

The same parts are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
