[0017] 1. The present invention cooperates with the positioning conveying mechanism, the hot pressing compounding mechanism, the driving mechanism and the locking mechanism. When the knitted fabric is heated unevenly during hot pressing compounding, the positioning conveying mechanism will suspend its work. At this time, the driving mechanism will be activated, thereby driving the hot pressing compounding mechanism to move, so as to re-hot press compound the knitted fabric between the positioning conveying mechanisms. While the driving mechanism is working, the locking mechanism will also be started to ensure that the re-hot pressing compounded fabric remains fixed to prevent it from shifting during the compounding process. This improvement significantly improves production efficiency and avoids the situation where the entire roll of fabric needs to be removed for secondary compounding due to uneven heating of the fabric.

[0018] 2. The present invention cooperates with the second hydraulic cylinder, the lifting plate, the fixed rod, the limiting ball, the sleeve and the second gear. By starting the second hydraulic cylinder, the fixed rod can be driven to move upward. At this time, the limiting ball in the fixed rod cooperates with the arc-shaped limiting groove inside the sleeve to drive the sleeve to rotate, thereby achieving gear rotation, and further providing power for the movement of the moving block.

[0019] 3. The present invention cooperates with the slider, connecting rod, limit block, locking block and spring so that when the lifting plate moves upward, the spring is driven to move upward, thereby driving the slider to move, and then driving the locking block upward through the connecting rod, so that the locking block abuts against the friction wheel, and the friction force generated between the locking block and the friction wheel limits the rotation of the friction wheel, thereby ensuring that the re-heat-pressed composite fabric remains fixed.

[0031] In a further embodiment, referring to Figure 3-Figure 4The hot pressing composite mechanism 3 includes a moving block 31 and a hot pressing roller 37. The left and right end surfaces of the workbench 1 are both provided with a limiting sliding hole 11. The moving block 31 is slidably connected inside the limiting sliding hole 11. The end of the moving block 31 away from the heating frame 6 is provided with a limiting hole 311. The limiting hole 311 is slidably connected with a mounting block 32. A rotating shaft 36 is rotatably connected between the two groups of mounting blocks 32. The hot pressing roller 37 is fixedly connected to the side wall of the rotating shaft 36. The end of the moving block 31 away from the hot pressing roller 37 is fixedly connected to a fixed seat 33. The upper end of the fixed seat 33 is fixedly connected to a first hydraulic cylinder 34. The output shaft end of the first hydraulic cylinder 34 is fixedly connected to the lower end of the mounting block 32. The upper end of the fixed seat 33 located at the left end of the workbench 1 is fixedly connected to a first motor 35. The output shaft end of the first motor 35 is fixedly connected to the left end of the rotating shaft 36.

[0032] In this embodiment, the first motor 35 can be used to drive the rotating shaft 36 to rotate, and the rotation of the rotating shaft 36 drives the hot pressing roller 37 to rotate, and cooperate with the heating frame 6 to perform hot pressing and compounding on the knitted fabric; when the hot pressing and compounding of the knitted fabric is uneven, the hot pressing roller 37 is driven to move by moving the moving block 31 backward. At this time, the first motor 35 is started and drives the hot pressing roller 37 to rotate in the opposite direction, so that the hot pressing roller 37 can roll on the upper end of the knitted fabric, thereby achieving the effect of repeated hot pressing.

[0033] In a further embodiment, referring to Figure 2 , Figure 5 and Figure 8 The positioning and conveying mechanism 2 includes a rotating shaft 21 and a conveying roller 22. The rotating shaft 21 is rotatably connected inside the front and rear sides of the workbench 1. Two groups of rotating shafts 21 are provided and arranged up and down. The side walls of the upper and lower groups of rotating shafts 21 are fixedly connected to the conveying rollers 22. The right end side walls of the upper and lower groups of rotating shafts 21 are fixedly connected to the first gears 23. The two groups of first gears 23 are meshed with each other. A second motor 25 is fixedly connected to the upper end of the workbench 1. The right ends of the two groups of rotating shafts 21 located on the upper side of the workbench 1 are connected to the output shafts of the second motor 25 through a synchronous belt drive assembly 26. The left ends of the two groups of rotating shafts 21 located on the lower side of the workbench 1 are fixedly connected to the friction wheels 24.

[0034] In this embodiment, through the second motor 25, since the right ends of the two groups of rotating shafts 21 located on the upper side of the workbench 1 are connected to the output shaft of the second motor 25 through the synchronous belt transmission assembly 26, the rotating shaft 21 is driven to rotate, and the rotation of the rotating shaft 21 drives the first gear 23 to rotate. Since the two groups of first gears 23 are meshed with each other, the two groups of rotating shafts 21 are driven to rotate at the same time. The rotation of the rotating shaft 21 drives the conveying roller 22 to rotate, and the knitted fabric is clamped by the two groups of conveying rollers 22. The knitted fabric can be driven to move on the upper end of the heating frame 6 through the rotation of the conveying roller 22, thereby providing power for the movement of the knitted fabric.

[0035] In a further embodiment, referring to Figure 5-Figure 7 The driving mechanism 4 includes a sleeve 45 and a fixed rod 43. The lower end of the cross plate 13 is fixedly connected to the second hydraulic cylinder 41. The output shaft end of the second hydraulic cylinder 41 is fixedly connected to the lifting plate 42. The left and right ends of the lifting plate 42 pass through the left and right sides of the workbench 1. The upper ends of the lifting plates 42 located on the left and right sides of the workbench 1 are fixedly connected to the fixed rods 43. The side walls above the fixed rods 43 are fixedly connected to the limiting balls 44. The left and right ends of the workbench 1 are rotatably connected with the sleeve 45 through the bearing seat. The sleeve 45 is provided with a buffer limiting groove 451 and an arc limiting groove 452. The buffer limiting groove 451 is located at the lower end of the arc limiting groove 452 and is connected. The limiting ball 44 is located in the buffer limiting groove 451 and is slidably connected thereto. The outer wall of the upper end of the sleeve 45 is fixedly connected to the second gear 46. A tooth groove 312 is provided on the end surface of the moving block 31 away from the heating frame 6, and the gear and the tooth groove 312 are meshed with each other.

[0036] In this embodiment, the lifting plate 42 is driven upward by starting the second hydraulic cylinder 41, and the upward movement of the lifting plate 42 drives the fixing rod 43 to move upward, thereby driving the limiting ball 44 to move upward, so that the limiting ball 44 slides in the buffer limiting groove 451 inside the sleeve 45 inside the arc limiting groove 452. When the limiting ball 44 slides inside the arc limiting groove 452, it will drive the sleeve 45 to rotate, and the rotation of the sleeve 45 drives the second gear 46 to rotate. Since the gear is meshed with the tooth groove 312, it provides power for the movement of the moving block 31.

[0037] In a further embodiment, referring to Figure 2 A locking mechanism 5 is provided at the left end of the workbench 1, and the locking mechanism 5 includes a slider 51 and a locking block 54. A vertical limit groove 12 is provided on the left end surface of the workbench 1, and a limit block 53 is slidably connected inside the vertical limit groove 12. The upper end of the limit block 53 on the left side of the workbench 1 is fixedly connected with a locking block 54, and the lower end of the limit block 53 on the left side of the workbench 1 is fixedly connected with a connecting rod 52. A slider 51 is fixedly connected between the two groups of connecting rods 52. The fixed rod 43 penetrates the slider 51 and is slidably connected thereto. A spring 55 is fixedly connected to the lower end of the slider 51, and the lower end of the spring 55 is fixedly connected to the upper end of the lifting plate 42.

[0038] In this embodiment, when the lifting plate 42 moves upward, the limiting ball 44 first slides inside the buffer limiting groove 451. When the lifting plate 42 moves upward, the spring 55 is driven to move upward, thereby driving the slider 51 to move upward. The slider 51 moves, and then drives the locking block 54 to move upward through the connecting rod 52, so that the locking block 54 abuts against the friction wheel 24. The friction force generated between the locking block 54 and the friction wheel 24 limits the rotation of the friction wheel 24, thereby ensuring that the re-hot pressed composite fabric remains fixed.
