[0023] The present invention is further described in detail below in conjunction with specific implementation methods.

[0024] Leather flanging machine Figure 1 , including an operating table 1, on which are arranged four rotating plates 21, 22, 23, 24 in a "mouth" shape, in the front, rear, left and right directions. The lower ends of the four rotating plates 21, 22, 23, 24 are respectively hinged to the operating table 1. The hinge axes of the rotating plates 21, 22, 23, 24 are parallel to the axes of the rotating plates 21, 22, 23, 24. Specifically, the axes of the front and rear rotating plates 21, 22 are in the left-right direction, and the hinge axes of the two rotating plates 21, 22 are also in the left-right direction. The axes of the left and right rotating plates 23, 24 are in the front-back direction, and the hinge axes of the two rotating plates 23, 24 are also in the front-back direction. Figure 3 The left rotating plate 23 extends to the right with front and rear clamping blocks 231 and 232, and the front and rear rotating plates 21 and 22 are respectively provided with front and rear clamping grooves 211 and 221 with slots facing left. Figure 1 In the state, the front and rear blocks 231, 232 of the left rotating plate 23 are respectively inserted into the front and rear slots 211, 221 of the front and rear rotating plates 21, 22 toward the right. In this state, the front rotating plate 21 cannot be rotated forward due to being blocked by the front block 231 of the left rotating plate 23, and the rear rotating plate 22 cannot be rotated backward due to being blocked by the rear block 232 of the left rotating plate 23. Figure 1 and Figure 2 The front surface of the front rotating plate 21, the rear surface of the rear rotating plate 22, the left surface of the left rotating plate 23 and the right surface of the right rotating plate 24 are all provided with electric heating plates 4.

[0025] See Figure 3The operating table 1 is provided with an installation opening 11, which is located behind the front rotating plate 21, in front of the rear rotating plate 22, to the right of the left rotating plate 23, and to the left of the right rotating plate 24. The leather flanging machine includes a driving mechanism 3, which includes a torsion spring 30, the front and rear ends 301 and 302 of which are connected to the front and rear rotating plates 21 and 22 respectively. Figure 1 , that is, when the front and rear rotating plates 21 and 22 have not rotated and unfolded, the torsion spring 30 is in an elastic deformation state, and its front and rear ends 301 and 302 apply forward and backward torques to the front and rear rotating plates 21 and 22 respectively. However, since the front and rear rotating plates 21 and 22 are blocked by the front and rear blocks 231 and 232 respectively, the front and rear rotating plates 21 and 22 will not rotate and unfold under the action of the torsion spring 30. The driving mechanism 3 includes left and right driving units 33 and 34. The left and right driving units 33 and 34 can respectively drive the left and right rotating plates 23 and 24 to rotate and unfold to the left and right. The left and right driving unit structures 33 and 34 are symmetrical. In this embodiment, the left driving unit 33 is taken as an example. Figure 6 The left driving unit 33 includes a left hinge block 331, a left connecting rod 332, a left extension rod 333 and a left electric push rod 334. The left hinge block 331 is arranged on the right end surface of the left rotating plate 23. The lower end of the left hinge block 331 extends downward into the installation opening 11. The upper end of the left connecting rod 332 is hinged to the lower end of the left hinge block 331. The lower end of the left connecting rod 332 is hinged to the upper end of the extension rod 333. The lower end of the left extension rod 333 is fixedly connected to the push rod body 3341 of the left electric push rod 334. The left electric push rod 334 is fixedly installed below the operating table 1. When the left electric push rod 334 is energized, the push rod body 3341 thereof moves upward, which will drive the left extension rod 333 to move upward, thereby driving the left connecting rod 332 to swing upward through the left extension rod 333. The upward swing of the left connecting rod 332 will drive the left hinge block 331 and the left rotating plate 23 to rotate to the left and unfold. After unfolding, as shown in FIG. Figure 7 As shown, that is, the worker only needs to energize the left electric push rod 334 of the left rotating unit 33 to drive the left rotating plate 23 to rotate to the left and unfold. If the left electric push rod 334 is powered off after the left rotating plate 23 is unfolded, the push rod body 3341 of the left electric push rod 334 will drive the left extension rod 333 to move downward and reset, thereby driving the left connecting rod 332 to swing downward through the left extension rod 333, and the left connecting rod 332 swinging downward will drive the left hinge block 331 and the left rotating plate 23 to rotate to the right and reset. After reset, Figure 6 That is to say, after the left rotating plate 23 is unfolded, the worker only needs to turn off the power of the left electric push rod 334 of the left driving unit 33 to drive the left rotating plate 23 to rotate rightward and reset. Figure 3 ) is symmetrical with the left drive unit 33, and will not be described in detail here. Figure 5, the worker only needs to energize the right electric push rod 344 of the right drive unit 34 to drive the right rotating plate 24 to rotate to the right and unfold. After the right rotating plate 24 unfolds, the worker only needs to de-energize the right electric push rod 344 of the right drive unit 34 to drive the right rotating plate 24 to rotate to the left and reset. This leather flanging machine includes a first power supply line (not shown in the figure). The power supply end of the first power supply line draws power from the outside, and the power supply end is electrically connected to the left and right electric push rods 334 and 344 of the left and right drive units 33 and 34 to supply power to the left and right electric push rods 334 and 344. The drive mechanism 3 includes a normally open first foot switch 35. The first foot switch 35 is connected in series on the first power supply line and disconnects the first power supply line under normal conditions, so that the left and right electric push rods 334 and 344 of the left and right drive units 33 and 34 are de-energized.

[0026] See Figure 1 and Figure 2 , when the leather 9 has a "mouth"-shaped opening 91, the worker uses this leather flanging machine to flange the four edges of the opening 91. The operation is as follows: First, put the leather 9 on the outside of the four rotating plates 21, 22, 23, and 24 so that the four rotating plates 21, 22, 23, and 24 enter the "mouth"-shaped opening 91 of the leather 9. In this state, the four edge fabrics 92 at the "mouth"-shaped opening 91 of the leather 9 are all located outside the four rotating plates 21, 22, 23, and 24; the worker applies glue on these four edge fabrics 92, and then steps on the first foot switch 35 to make the first foot switch 35 conduct the first power supply line, so that the left and right electric push rods 334 and 344 of the left and right drive units 33 and 34 are energized. See Figure 3 and Figure 5 , then the left and right electric push rods 334 and 344 of the left and right drive units 33 and 34 respectively drive the left and right rotating plates 23 and 24 to rotate to the left and right and unfold. The front and rear clamping blocks 231 and 232 of the left rotating plate 23 will disengage from the front clamping groove 211 of the front rotating plate 21 and the rear clamping groove 221 of the rear rotating plate 22. The front and rear rotating plates 21 and 22 are no longer blocked by the front and rear clamping blocks 231 and 232 of the left rotating plate 23, and the front and rear rotating plates 21 and 22 will respectively rotate forward and backward under the torsion of the torsion spring 30. That is to say, the drive mechanism 3 drives the four rotating plates 21, 22, 23, and 24 to rotate and unfold towards the outside of the "mouth" shape respectively. During this process, the four rotating plates 21, 22, 23, and 24 respectively press the four edge fabrics 92 of the leather 9 onto the leather body 90, so that the four edges of the "mouth"-shaped opening 91 of the leather 9 can be flanged simultaneously, saving time and effort. The electric heating sheets 4 on the four rotating plates 21, 22, 23, and 24 can heat the four edge fabrics 92 after flanging to accelerate the curing of the glue. The cured leather 9 is as Figure 4 shown.

[0027] See Figure 5The driving mechanism 3 also serves as a reset mechanism, and its left and right driving units 33 and 34 can respectively drive the left and right rotating plates 23 and 24 to rotate and reset. The driving mechanism 3 also includes front and rear reset units 31 and 32, which can respectively drive the front and rear rotating plates 21 and 22 to rotate and reset. The front and rear reset units 31 and 32 are symmetrical in structure, and the front reset unit 31 is taken as an example in this embodiment. Figure 8 The front reset unit 31 includes a front hinge block 311, a front connecting rod 312, a front extension rod 313 and a front electric push rod 314. The front hinge block 311 is arranged on the rear end surface of the front rotating plate 21. The lower end of the front hinge block 311 extends downward into the installation opening 11. The upper end of the front connecting rod 312 is hinged to the lower end of the front hinge block 311. The lower end of the front connecting rod 312 is hinged to the upper end of the front extension rod 313. The lower end of the front extension rod 313 is movably connected to the push rod body 3141 of the front electric push rod 314 and can move up and down along the push rod body 3141 of the front electric push rod 314. The upper end of the push rod body 3141 of the front electric push rod 314 is provided with a retaining ring 3142. The retaining ring 3142 blocks the front extension rod 313 so that the front extension rod 313 cannot be separated from the push rod body 3141 of the front electric push rod 314 upward. The front electric push rod 314 is fixedly installed below the operating table 1. Rear reset unit 32 (see Figure 5 ) is symmetrical with the front reset unit 31, and will not be described here. The leather flanging machine includes a second power supply line (not shown in the figure), the power supply end of the second power supply line takes power from the outside, and the power supply end supplies power to the front and rear electric push rods 314, 324 of the front and rear reset units 31, 32, and supplies power to the front and rear electric push rods 314, 324. Figure 5 The driving mechanism 3 includes a normally open second foot switch 36, which is connected in series to the second power supply line. Under normal circumstances, the second power supply line is disconnected to cut off the power to the front and rear electric push rods 314 and 324 of the front and rear reset units 31 and 32.

[0028] See Figure 5 , Figure 8 , Fig. 9 and Fig.10, the worker steps on the second foot switch 36 before stepping on the first foot switch 35. At this time, the second foot switch 36 conducts the second power supply line to energize the front and rear electric push rods 314 and 324 of the front and rear reset units 31 and 32, and the push rod bodies 3141 and 3241 of the front and rear electric push rods 314 and 324 extend upward. After the push rod bodies 3141 and 3241 of the front and rear electric push rods 314 and 324 extend upward, the worker steps on the first foot switch 35 to control the four rotating plates 21, 22, 23, and 24 to rotate and unfold. In this process, taking the front rotating plate 21 as an example, the front rotating plate 21 rotates forward and unfolds, which drives the front hinge block 311 to rotate forward, and the front hinge block 311 drives the front connecting rod 312 to swing upward, and the front connecting rod 312 drives the front extension rod 313 to move upward along the push rod body 3141 of the front electric push rod 314. After the flanging is completed, the worker first releases the second foot switch 36 to disconnect the second power supply line so as to cut off the power supply to the front and rear electric push rods 314 and 324 of the front and rear reset units 31 and 32. Taking the front reset unit 31 as an example, the push rod body 3141 of the front electric push rod 314 of the front reset unit 31 drives the front extension rod 313 to move downward and reset, thereby driving the front connecting rod 312 to swing downward, and the swinging of the front connecting rod 312 drives the front hinge block 311 and the front rotating plate 21 to rotate backward and reset. Correspondingly, the rear electric push rod 324 of the rear reset unit 32 also drives the rear rotating plate 22 to rotate forward and reset. After the front and rear rotating plates 21 and 22 are reset, the worker releases the first foot switch 35 to disconnect the first power supply line, thereby powering off the left and right electric push rods 334 and 344 of the left and right driving units 33 and 34, and then the left and right electric push rods 334 and 344 of the left and right driving units 33 and 34 respectively drive the left and right rotating plates 23 and 24 to rotate and reset. When the four rotating plates 21, 22, 23, and 24 are all reset, the worker can take out the leather 9 that has been turned up.

[0029] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
