Description

Technical Field

[0001] This utility model relates to the field of fabric processing equipment technology, specifically a shaping mechanism for hot pressing of polypropylene fabric. Background Technology

[0002] Knitted fabric is a type of fabric formed by bending yarns into loops and interlocking them using knitting needles. It is divided into warp-knitted fabric and weft-knitted fabric. Knitted fabric is a soft and elastic material. During the manufacturing process, due to the loose fibers, knitted fabric is prone to deformation. Therefore, setting technology is a very important step to help knitted fabric maintain good dimensional stability and shape. The common setting method for knitted fabric is to use a hot press to heat and set it.

[0003] The current setting mechanism does not properly stretch and flatten the knitted fabric during the heat setting and conveying process, resulting in insufficient stretching and setting of the knitted fabric during conveying, which affects the quality of subsequent setting processes. At the same time, the fabric is too hot after heat setting, making it difficult for workers to remove it for cooling and collection immediately.

[0004] This case arose in order to resolve the aforementioned issues. Summary of the Invention

A heating roller is provided below the flat plate. Multiple conveying rollers are provided inside the shaping box. An inlet and an outlet are respectively opened on the side walls of the shaping box. A collection box is provided on the side wall of the shaping box, and the collection box is directly opposite the outlet. A clamping structure is provided on the collection box.

[0007] Preferably, the clamping structure includes a threaded rod, a moving block, a support block, a displacement column, and a clamping block.

A second motor is provided above the cross column, and the output end of the second motor is fixedly connected to a transmission belt.

[0008] Preferably, the transmission belt passes through the cross column and connects to the middle position of the threaded rod. The threaded rod has its threads on the left and right sides arranged in opposite directions with the center of the transmission belt connection as the midpoint. Moving blocks and support blocks are slidably connected to the threaded rods on both sides. A rotating gear is rotatably connected to the inner side of the moving block, and a clamping block is fixed on the rotating gear.

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-4As shown: A shaping mechanism for hot pressing of polypropylene fabric includes a shaping box 1 and a conveying roller 2. A heating box 3 is provided on the top of the shaping box 1. The heating box 3 is connected to a flat plate 4 that extends into the interior of the shaping box 1. A heating roller 5 is provided below the flat plate 4. Multiple conveying rollers 3 are provided inside the shaping box 1. The side walls of the shaping box 1 are respectively provided with an inlet and an outlet 6. A collection box 7 is provided on the side wall of the shaping box 1, which is directly opposite the outlet 6. The collection box 7 is provided with a clamping structure. In use, the knitted fabric enters the shaping box 1 through the inlet channel. The knitted fabric passes through the conveying roller 2 in sequence. The flat plate 4 falls and moves towards the knitted fabric, so that the heating roller 5 contacts the knitted fabric. At the same time, a fan can be provided below the shaping box 1 to blow hot air onto the fabric. The conveying roller on the right side rolls up to the right to stretch and shape the heated knitted fabric and send it out of the outlet 6.

[0017] The working principle of the clamping structure is as follows: First, the drive motor 8 drives the support column 9 to move until the clamping block 16 is aligned with the fabric fed from the outlet 6. Then, the second motor 10 drives the transmission belt 13 to rotate, thereby driving the threaded rod 11 to rotate, which in turn drives the moving block 12 and the support block 14 on it to move synchronously to the appropriate position. Then, the micro motor drives the displacement column 15 to move backward. At this time, the rack 19 on it moves forward, thereby driving the two rotating gears 18 meshing with it to rotate clockwise, so that the two opposing clamping blocks 16 move to the corresponding clamping surfaces, thereby clamping the fabric. Then, the output of the reverse drive motor 8 causes the support column 9 to move away from the shaping box 1 to the appropriate position. Then, the output of the reverse micro motor is reversed, the displacement column 15 moves forward, driving the rotating gears 18 to rotate counterclockwise, and the two clamping blocks 16 rotate outward, releasing the fabric, which then falls into the collection box 7.

[0018] The clamping structure includes a threaded rod 11, a moving block 12, a support block 14, a displacement column 15, and a clamping block 16. The collection box 7 is provided with two slide rails, and a support column 9 is slidably connected in the slide rails. The two support columns 9 are fixedly connected by a cross column. A second motor 10 is provided above the cross column. The output end of the second motor 10 is fixedly connected to the transmission belt 13. The threaded rod 11 is driven to rotate by the rotation of the transmission belt 13.

[0019] The transmission belt 13 passes through the cross column and connects to the middle position of the threaded rod 11. The threaded rod 11 has its threads on the left and right sides reversed with the center point of the connection of the transmission belt 13 as the midpoint. Therefore, when the threaded rod 11 rotates, the two corresponding moving blocks 12 and the support block 14 on it will move inward or outward synchronously to ensure that the positions are corresponding. Moving blocks 12 and support blocks 14 are slidably connected on the left and right sides of the threaded rod 11. A rotating gear 18 is rotatably connected to the inner side of the moving block 12. A clamping block 16 is fixed on the rotating gear 18. The rotating gear 18 is provided with a long strip of teeth to achieve limit and prevent excessive rotation.

[0020] The support block 14 is equipped with a micro motor, the output end of which is connected to the displacement column 15. The displacement column 15 is provided with racks 19 directly above and below it. A rotating gear 18 is rotatably connected to the inner wall of the support block 14.

[0021] The two rotating gears mesh with the upper and lower racks 19 of the displacement column 15 respectively. When the displacement column 15 moves, it drives the two rotating gears 18 to rotate synchronously. The support block 14 is "L" shaped, so that the rotating gear 18 connected to its inner wall corresponds to the rotating gear 18 connected inside the moving block 12. The positions of the two clamping blocks 16 correspond, and the middle position of the two clamping blocks 16 corresponds to the discharge port 6.

[0022] The end of the support column 9 is connected to the output end of the drive motor 8 to enable the support column 9 to move within the slide rail.

[0023] Determine the scope of its protection.
