Description

Technical Field

[0001] This utility model relates to the field of fabric spreading technology for pre-shrinking machines, and in particular to a spreading device for a pre-shrinking machine. Background Technology

[0002] A pre-shrinking machine, also known as an anti-shrinking machine, is a piece of equipment for pre-shrinking and finishing fabrics. It refers to the process where, under suitable humid and hot conditions, the weft density and radial shrinkage of a fabric are increased to a certain extent by utilizing the expansion and contraction deformation of an elastic blanket, thereby creating a relaxed structure. When the fibers are mixed and swollen, the radial length is no longer shortened, resulting in a significant reduction in the shrinkage rate of the finished product.

[0003] Steam pre-shrinking machines are a common type of fabric pre-shrinking machine. They use steam heating to pre-shrink the fabric. Specifically, high-temperature steam is injected into the fabric being treated, placing it in a high-temperature and humid environment. This causes the fibers in the fabric to deform to a certain extent, thus achieving the pre-shrinking effect. However, when using current steam pre-shrinking machines, the fabric shrinks and gathers towards the center when exposed to high-temperature steam. Workers need to manually and continuously pull the fabric to flatten the edges. This not only wastes a lot of manpower when using current steam pre-shrinking machines, but also results in low production efficiency.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a flattening device for a pre-shrinking machine in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flattening device for a pre-shrinking machine, comprising a supporting base plate, a supporting column fixedly installed on the upper end of the outer wall of the supporting base plate, a mounting seat fixedly connected to the upper end of the outer wall of the supporting column, a conveyor belt assembly provided on the upper end of the outer wall of the mounting seat, and fixed frames symmetrically fixedly installed on the upper end of the outer wall of the mounting seat, with rotating rollers linearly arranged and rotatably mounted on both the left and right fixed frames.

[0007] As a further improvement of this utility model, the rotating roller is a rubber roller.

[0008] As a further embodiment of this utility model: the inner wall of the fixed frame is linearly arranged and rotatably connected to rotating blocks one, and the outer walls of all rotating blocks one on the left and right sides are rotatably connected to rotating shafts at their opposite ends, and rotating rollers are fixedly installed on the side walls of the rotating shafts.

[0009] As a further embodiment of this utility model: the lower end of the outer wall of the mounting base is symmetrically connected to electric telescopic rods on both the front and rear sides, and the upper end of the output end of each electric telescopic rod on the left and right sides is rotatably connected to a connecting rod. The upper end of the outer wall of each connecting rod on the left and right sides is simultaneously rotatably connected to a movable frame. Rotating blocks two are linearly arranged and rotatably connected to the inner wall of the movable frame. A connecting frame is fixedly installed at the end of the rotating block two near the fixed frame. The connecting frame is rotatably connected to the rotating shaft.

[0010] As a further embodiment of this utility model: a drive motor is fixedly installed on the inner wall of the connecting frame, and the output end of the drive motor passes through the connecting frame and is fixedly connected to the rotating shaft.

[0011] As a further improvement of this utility model: the upper end of the outer wall of the rotating roller is flush with the upper end of the outer wall of the conveyor belt assembly.

[0012] As a further improvement of this utility model: each of the movable frames has a support rod symmetrically fixedly connected to the lower end of its outer wall, and all the support rods have universal wheels fixedly installed on their lower ends.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses the rotation of a conveyor belt assembly to move the fabric above it. At the same time, an electric telescopic rod drives the moving frames on both sides to move, thereby changing and adjusting the rotation angle of the rotating rollers on both sides. The start of the drive motor drives the rotating shaft to rotate, which in turn drives the rotating rollers to rotate. The rotation of the rotating rollers applies a pulling force to the left and right sides to pull the fabric passing by and flatten it out. This achieves automatic spreading and flattening of the fabric passing by the device, eliminating the need for manual straightening and flattening by workers, and greatly improving the efficiency of the pre-shrinking machine in processing fabric.

[0015] 2. When in use, this utility model provides additional support for the moving frame and rotating roller by installing support rods and casters, making the moving frame more stable and secure when moving and the rotating roller when performing flattening operations, thereby improving the stability of the device.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a flattening device for a pre-shrinking machine: it includes a supporting base plate 100, a supporting column 110 fixedly installed on the upper end of the outer wall of the supporting base plate 100, a mounting base 200 fixedly connected to the upper end of the outer wall of the supporting column 110, a conveyor belt assembly 210 provided on the upper end of the outer wall of the mounting base 200, and fixed frames 220 symmetrically fixedly installed on the upper end of the outer wall of the mounting base 200. Rotating rollers 300 are linearly arranged and rotatably installed on both left and right fixed frames 220, and the fabric above them is conveyed and moved by the rotation of the conveyor belt assembly 210.

[0024] Please refer to this carefully. Figure 1-3 The inner wall of the fixed frame 220 is linearly connected to rotating blocks 400. All rotating blocks 400 on the left and right sides are rotatably connected to rotating shafts 410 on their opposite ends. Rotating rollers 300 are fixedly installed on the side walls of rotating shafts 410. Electric telescopic rods 500 are symmetrically connected to the lower end of the outer wall of the mounting base 200 on both the front and rear sides. Connecting rods 510 are rotatably connected to the upper end of the output end of each electric telescopic rod 500 on the left and right sides. Moving frames 520 are rotatably connected to the upper end of the outer wall of each connecting rod 510 on the left and right sides. Rotating blocks 530 are linearly connected to the inner wall of the moving frame 520. Connecting frames 540 are fixedly installed at the end of rotating blocks 530 near the fixed frame 220. Connecting frames 540 are rotatably connected to rotating shafts 410.

[0025] In this embodiment: by activating the electric telescopic rod 500, the moving frames 520 on both sides are moved, thereby changing and adjusting the rotation angle of the rotating rollers 300 on both sides. The rotation of the rotating rollers 300 applies a pulling force to the upper fabric to the left and right, pulling the fabric to the left and right to flatten it.

[0026] Please refer to this carefully. Figure 4 and 5 As shown, a drive motor 600 is fixedly installed on the inner wall of the connecting frame 540. The output end of the drive motor 600 passes through the connecting frame 540 and is fixedly connected to the rotating shaft 410. The drive motor 600 drives the rotating shaft 410 to rotate, thereby driving the rotating roller 300 to rotate.

[0027] In this embodiment, the upper end of the outer wall of the rotating roller 300 is flush with the upper end of the outer wall of the conveyor belt assembly 210, thereby ensuring that the fabric can maintain stable contact with both the rotating roller 300 and the conveyor belt assembly 210. The rotating roller 300 is a rubber roller, which has a large coefficient of friction, thereby ensuring a large frictional force between the rotating roller 300 and the fabric.

[0028] Please refer to this carefully. Figure 1 and Figure 2 As shown, each movable frame 520 has a support rod 700 symmetrically fixedly connected to the lower end of its outer wall. All the support rods 700 have casters 710 fixedly installed on the lower end of their outer walls. The support rods 700 and casters 710 can provide additional support for the movable frame 520 and the rotating roller 300 above, making the movable frame 520 more stable when moving and in use.

[0029] The working principle of this utility model is as follows: During use, the device moves the fabric above it by rotating the conveyor belt assembly 210. At the same time, the electric telescopic rod 500 is activated to move the moving frames 520 on both sides, thereby changing and adjusting the rotation angle of the rotating rollers 300 on both sides. The drive motor 600 is activated to drive the rotating shaft 410 to rotate, thereby driving the rotating rollers 300 to rotate. The rotation of the rotating rollers 300 applies a pulling force to the fabric above to the left and right, pulling the fabric to the left and right to flatten it. Furthermore, all the support rods 700 are fixedly installed with universal wheels 710 at the lower end of their outer walls. The support rods 700 and universal wheels 710 provide additional support for the moving frames 520 and rotating rollers 300 above, making the moving frames 520 more stable during movement and use.
