[0021] See also Figures 1 to 4The present invention relates to a knitted fabric shaping device. On both sides of the device, an unwinding machine and a winding machine for knitted fabric rolls are respectively arranged to realize automatic conveying of knitted fabric during shaping processing. The present invention relates to a prior art device. The device comprises a shaping table 1. A concave frame 2 is fixedly connected to the center line of the upper side wall of the shaping table 1. The upper end of the concave frame 2 is fixedly connected to a hydraulic cylinder 3. The lower end of the hydraulic cylinder 3 passes through the concave frame 2 and is fixedly connected to a pressure relief mechanism. The lower end of the pressure relief mechanism is fixedly connected to an upper hot pressing plate 4. A lower hot pressing plate 5 is fixedly connected to the upper side wall of the shaping table 1 directly below the upper hot pressing plate 4. The upper hot pressing plate 4 and the lower hot pressing plate 5 are plate bodies with electric heating plates installed inside. The present invention relates to a common prior art device. Both ends of the shaping table 1 are fixedly connected to a stretching shaping device for positioning and stretching the two side edges of the knitted fabric. The hydraulic cylinder 3 pushes the upper hot pressing plate 4 to move downward, and performs hot pressing and shaping processing on the knitted fabric conveyed to the lower hot pressing plate 5.

[0022] The stretching and shaping device includes a fixed strip shell 6 fixed at one end of the shaping table 1, one end of the fixed strip shell 6 is inserted and rotatably connected to a first hand rod 7, one end of the first hand rod 7 extends into the fixed strip shell 6 and is fixedly connected to a bidirectional screw rod 8, two symmetrically arranged threaded blocks 9 are threadedly connected to the bidirectional screw rod 8, and the upper sides of the two threaded blocks 9 are fixedly connected to a connecting block 10, the upper side wall of the fixed strip shell 6 is provided with two openings, and the two connecting blocks 10 are respectively passed through the two openings and are fixedly connected to a movable strip shell 11, and the two movable strip shells 11 are provided with a spacing adjustment mechanism. A sliding opening is provided on one side of the moving strip shell 11, and both ends of the spacing adjustment mechanism pass through the sliding opening and are rotatably connected to clamping rollers 12. When the two sets of clamping rollers 12 clamp the two side edges of the knitted cloth respectively, the first hand rod 7 is rotated to drive the bidirectional screw rod 8 to rotate. Since the bidirectional screw rod 8 is threadedly connected to the two threaded blocks 9 respectively, at this time, the two threaded blocks 9 are forced to move in opposite directions, thereby driving the two clamping rollers 12 to stretch and position the two side edges of the knitted cloth to prevent the knitted cloth from wrinkling during transportation, thereby ensuring the quality of subsequent hot pressing and shaping processing.

[0023] like Figure 3 and Figure 4As shown: the spacing adjustment mechanism includes a second hand rod 13 inserted into one side of the moving bar housing 11 and rotatably connected thereto, one end of the second hand rod 13 extends into the moving bar housing 11 and is fixedly connected to a driving bevel gear 14, both ends of the inner wall of the moving bar housing 11 are rotatably connected to threaded rods 15 through a first bearing seat, and the adjacent ends of the two threaded rods 15 are fixedly connected to a driven bevel gear 16 meshing with the driving bevel gear 14, the two threaded rods 15 are threadedly connected to nut blocks 17, and the same side of the two nut blocks 17 are fixedly connected to a connection block 18, and the moving bar housing Two sliding openings are provided on one side of 11, and two connecting blocks 18 pass through the two sliding openings respectively and are rotatably connected with the two clamping rollers 12 respectively, so that the side edge of the knitted cloth is placed between the two clamping rollers 12, and the second hand lever 13 is rotated. Since the active bevel gear 14 is meshed with the two driven bevel gears 16, the two threaded rods 15 are driven to rotate in opposite directions at the same time. At this time, since the two threaded rods 15 are threadedly connected with the two nut blocks 17, the two nut blocks 17 are forced to move toward each other, driving the two clamping rollers 12 to clamp the side wall of the knitted cloth for positioning, and the positioning is firm to prevent falling off.

[0024] like Figure 2 As shown: the pressure relief mechanism includes a mounting plate 19 fixedly connected to the lower end of the hydraulic cylinder 3, and two symmetrically arranged sliding rods 20 are inserted and slidably connected to the mounting plate 19. The lower end of the sliding rod 20 is fixedly connected to the upper hot pressing plate 4, and a pressure relief spring 21 is fixedly connected between the mounting plate 19 and the upper hot pressing plate 4. The pressure relief spring 21 is sleeved on the sliding rod 20. When the hydraulic cylinder 3 pushes the upper hot pressing plate 4 downward, the upper hot pressing plate 4 performs hot pressing and shaping processing on the knitted fabric on the lower hot pressing plate 5. At this time, the mounting plate 19 slides on the sliding rod 20, and the pressure relief spring 21 is squeezed and contracted to generate elastic force, which can buffer the extrusion force of the upper hot pressing plate 4 on the lower hot pressing plate 5 to prevent damage caused by excessive pressure.

[0025] like Figure 2 As shown: the upper end of the slide bar 20 is fixedly connected to a limit stopper 22 to prevent the slide bar 20 from being separated from the mounting plate 19.

[0026] like Figure 4 As shown: the inner wall of the fixed bar housing 6 is rotatably connected to the end of the bidirectional screw rod 8 away from the first hand rod 7 through the second bearing seat, which can support the rotation of the bidirectional screw rod 8.

[0027] like Figure 1 As shown: the front side wall of the concave frame 2 is fixedly connected with a control panel 23, and the control panel 23 is electrically connected to the hydraulic cylinder 3, the upper hot pressing plate 4 and the lower hot pressing plate 5 respectively, which is convenient to operate and has an external power supply. The circuit involved is the existing technology and can be fully implemented by those skilled in the art without further explanation.

[0028] like Figure 1As shown: the upper side walls of the shaping table 1 located on both sides of the lower hot pressing plate 5 are provided with two symmetrically arranged supporting rollers 24, which can support the conveyance of the knitted fabric during the shaping process.

[0029] Working principle: When the knitted fabric is subjected to hot pressing and shaping processing, the side edge of the knitted fabric is placed between the two clamping rollers 12, and the second hand rod 13 is rotated. Since the active bevel gear 14 is meshed with the two driven bevel gears 16, the two threaded rods 15 are driven to rotate in opposite directions at the same time. At this time, since the two threaded rods 15 are threadedly connected with the two nut blocks 17, the two nut blocks 17 are forced to move toward each other, driving the two clamping rollers 12 to clamp the side wall of the knitted fabric for positioning. The positioning is firm to prevent it from falling off. Then, the first hand rod 7 is rotated to drive the bidirectional screw rod 8 to rotate. Since the bidirectional screw rod 8 is threadedly connected with the two threaded blocks 9 respectively, the two threaded blocks 9 are forced to move in opposite directions, driving the two clamping rollers 12 to stretch and position the two side edges of the knitted fabric to prevent the knitted fabric from wrinkling during transportation, thereby ensuring the quality of subsequent hot pressing and shaping processing.

[0030] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
