The side plate 20 is erected on the frame 2, the workbench 30 is arranged on the frame 2 and is located on one side of the side plate 20. The third welding machine 31 is arranged at the bottom of the workbench 30, and the welding part of the third welding machine 31 extends to the upper surface of the workbench 30; the mounting frame 32 is arranged on one side of the side plate 20, and the lower end extends above the workbench 30. The lifting frame 33 is slidably connected in the mounting frame 32, the lifting driving member 34 is arranged on the mounting frame 32 and is connected to the lifting frame 33 for driving the lifting frame 33 to move up and down. An installation plate 330 is arranged in the lifting frame 33, the lifting mechanism 35 is arranged on the installation plate 330, and the welding upper die 36 is arranged at the bottom end of the lifting mechanism 35. The translation mechanism 37 is arranged at the bottom end of the lifting frame 33, and a clearance position for avoiding the welding upper die is arranged on the translation mechanism 37. The two groups of second clamping mechanisms 39 are relatively arranged on both sides of one end of the translation mechanism 37 close to the side plate 20, the first clamping mechanism 38 is arranged on the translation mechanism 37, and the clamping position of the first clamping mechanism 38 extends between the clamping positions of the two second clamping mechanisms 39. The translation mechanism 37 drives the first clamping mechanism 38 and the two second clamping mechanisms 39 to extend to the bottom end of the shearing mechanism 16, the two second clamping mechanisms 39 respectively clamp the free ends of the first cloth belt and the second cloth belt, and the first clamping mechanism 38 clamps the middle section of the first cloth belt, so that the cloth belt is in a "T" shape.

[0061] For this T-shaped belt welding equipment, when the T-shaped belt cut by the T-shaped belt forming device 1 is conveyed downward, the first clamping mechanism 38 and the two groups of second clamping mechanisms 39 are driven to extend towards the T-shaped belt, so that the first clamping mechanism 38 clamps the middle section of the T-shaped belt, and the two second clamping mechanisms 39 clamp the two ends of the T-shaped belt, so that the two ends of the T-shaped belt open outwards. The translation mechanism 37 drives the first clamping mechanism 38 and the two groups of second clamping mechanisms 39 to retract, so that the T-shaped belt is located above the workbench 30, and the lifting driving member 34 drives the lifting frame 33 to move downward, so that the T-shaped belt fits on the connecting body on the workbench 30. The lifting mechanism 35 drives the welding upper die 36 to press down, presses the T-shaped belt on the welding part of the third welding machine 31, and under the action of the third welding machine 31, completes the welding of the T-shaped belt and the connecting body, thereby replacing manual sewing or welding, and then realizing the automatic forming of the T-shaped belt and the automatic welding on the connecting body, improving the efficiency and reducing the cost.

[0062] Further, referring to Figure 10 and Figure 12, the translation mechanism 37 includes a connecting frame 370, a translation frame 371, and a driving cylinder 372. The connecting frame 370 is connected to the bottom end of the lifting frame 33. Both the connecting frame 370 and the translation frame 371 are semi-closed frames formed by three connecting plates. The translation frame 371 is slidably connected within the connecting frame 370.

[0063] Furthermore, the first clamping mechanism 38 includes a pneumatic parallel clamp and extended clamping jaws provided on the two clamping jaws of the parallel clamp.

[0064] Further, the upper welding die 36 includes a fixed connecting plate 360 provided at the bottom end of the lifting mechanism 35, and two welding dies 361 oppositely arranged at the bottom of the fixed connecting plate 360. The two welding dies 361 are located on both sides of the clamping jaws of the first clamping mechanism 38. During welding, the driving of the translation mechanism 37 causes the first clamping mechanism 38 holding the cloth tape to move, so that the two ends of the T-shaped cloth tape are located at the bottom ends of the two welding dies 361, thereby completing the welding of the cloth tape.

[0065] Further, please refer to Figure 10 , on one side of the two welding dies 361 close to the side plate 20, guide plates 362 are also provided. The two guide plates 362 form a guiding angle for guiding the cloth tape between the two welding dies 361. Therefore, when the first clamping mechanism 38 clamps the T-shaped cloth tape between the two welding dies 361, the guide plates 362 play a guiding role to prevent the T-shaped cloth tape from touching the sides of the welding dies 361.

[0066] Further, refer to Figures 9 - 13, a turning mechanism 4 is further provided on the side plate 20, and the turning mechanism 4 is arranged at the bottom end of the shearing mechanism 14. Two turning members 40 are provided on the turning mechanism 4, and suction cups 41 are arranged on both of the two turning members 40. The suction cups 41 are connected to a negative pressure system. The turning mechanism 4 drives the two turning members 40 to turn 90°, so that the end of the cloth tape adsorbed by the suction cups 41 turns 90° and faces the clamping position of the second clamping mechanism 39. Specifically in this embodiment, when the T-shaped tape conveyed down is located between the two second clamping mechanisms 39, the two suction cups face the side surfaces of both ends of the T-shaped cloth tape. Therefore, the suction cups adsorb on the side surface of the T-shaped cloth tape. The turning mechanism 4 drives the suction cups 41 to turn downward by 90°, so that the turned end of the T-shaped cloth tape faces between the clamping positions of the second clamping mechanism 39, and the second clamping mechanism 39 clamps the end of the T-shaped tape.

[0067] Further, referring to Figure 13 , the turning mechanism 4 includes a connecting seat 42, a cylinder 43, a connecting rod 44, a support 45, a hinge 46 and a connecting block 47.

In this embodiment, by pressing or pulling the connecting rod 44 downward or upward by the cylinder 43, the two hinges of the hinge 46 are opened and closed, and thus the turning member 40 is turned.

[0068] Further, referring to Figure 9 , a material guiding track 5 is further provided on one side of the side plate 20, and the lower end of the material guiding track 5 extends between the two second clamping mechanisms 39; the material guiding track 5 is provided with a track groove 50 with an opening facing the translation mechanism 37, and the upper end of the track groove 50 is in a trumpet shape; the lower end of the material guiding track 5 is provided with a clearance notch for clearing the clamping position of the first clamping mechanism 38. When the T-shaped tape is conveyed downward, the T-shaped tape is aligned through the track groove 50, and thus it is convenient to convey the T-shaped tape between the two second clamping mechanisms 39.

[0069] Further, the mounting bracket 32 is fixedly connected to one side of the side plate 20.

[0070] Further, referring to Figure 8, the side plate 20 and the workbench 30 are both slidably connected to the frame 2, and a first adjusting screw 23 for adjusting the side plate 20 and a second adjusting screw 24 for adjusting the workbench 30 are further provided on the frame 2. According to the different positions of the T-shaped belt welding, it is necessary to adjust the position of the T-belt and the main body provided on the workbench 30.
