Description

Technical Field

[0001] The present invention relates to the technical field of wet cotton pretreatment, and more specifically to an automatic wet cotton turning and tray taking machine. Background Art

[0002] In the existing dyeing process, for the wet cotton formed into a cake shape by adding water and squeezing, the technical treatment of dehydration and loosening is as follows: First, the wet cotton is lifted to the tail of the opener by a traveling crane and placed flat on its pallet. Then, the pallet is lifted 90° upward from the rearmost end by hydraulic pressure, so that the cotton cake is inverted 90° as a whole inside the conveyor belt. The chassis is taken out and sent forward, and then the cotton is dispersed by a beater, and then enters the feeding machine. Its disadvantages are as follows: 1. The wet cotton cake on the pallet is generally about 400KG. Using hydraulic pressure to lift it forcefully results in high fuel consumption and power consumption, and it often needs to be maintained, with high costs. 2. Due to the large weight of the wet cotton, the conveyor belt is squeezed by it, and it is inevitable that the conveying is not smooth, unstable, and the conveyor belt is damaged. 3. When the wet cotton enters the beater for loosening, without any partition, it is freely opened and struck, resulting in uneven force on the beater, uneven cotton block sizes, poor cotton opening uniformity, and even jamming, which will cause uneven drying in the subsequent dryer, reduce the efficiency of the dryer, and increase the difficulty of subsequent processing.

[0003] Therefore, how to provide an automatic wet cotton turning and tray taking machine is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] The present invention aims to solve the above technical problems in the prior art to a certain extent, and provides an automatic wet cotton turning and tray taking machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An automatic wet cotton turning and tray taking machine, comprising: a fixed frame;

[0007] A first turning and cotton feeding mechanism, which is horizontally arranged on the fixed frame, and its middle part is rotationally connected to the fixed frame;

[0008] A second turning and cotton feeding mechanism, which is located below the discharging end of the first turning and cotton feeding mechanism and is arranged in parallel with the first turning and cotton feeding mechanism. The middle part of the second turning and cotton feeding mechanism is rotationally connected to the fixed frame;

[0009] A beater mechanism, which includes a machine shell, a beater assembly and a conveyor belt. The machine shell is located below the discharging end of the second turning and cotton feeding mechanism. The top of the machine shell is provided with falling cotton grille holes. The beater assembly is arranged inside the machine shell and reciprocates horizontally. The conveyor belt is inclined and arranged below the beater assembly, and one end extends out of the machine shell and is connected to a pre-opener.

[0010] Through the above solution, the present invention can automatically tilt and flip forward to complete the removal of the wet cotton tray only by its own displacement, without the need for a hydraulic device. The cotton cake only undergoes two automatic flips and then falls on the top of the machine shell. Through the barrier at the top of the machine shell, the cotton grabbing beater inside the machine shell rotates to grab the cotton. The grabbed cotton blocks are small, uniform, and have a high degree of loosening, without the worry of large and small cotton blocks. The support moves back and forth along one side of the slide rail, and while the cotton grabbing beater grabs the wet cotton, it easily sends it downward, achieving overall average grabbing.

[0011] Further, the first flip and cotton feeding mechanism includes a first bracket, a first movable roller, a first driving roller, and a first driving motor. A plurality of the first movable rollers are provided and symmetrically distributed on both sides of the first driving roller. Both the first movable roller and the first driving roller are rotatably connected in the first bracket, and one end of the first driving roller penetrates through the first bracket and is pivotally connected to the fixed frame. A synchronous transmission belt is sleeved outside the plurality of first movable rollers and the first driving roller, and the first driving roller is in transmission connection with the first driving motor.

[0012] Further, the second flip and cotton feeding mechanism includes a second bracket, a second movable roller, a second driving roller, and a second driving motor. A plurality of the second movable rollers are provided and symmetrically distributed on both sides of the second driving roller. Both the second movable roller and the second driving roller are rotatably connected in the second bracket, and one end of the second driving roller penetrates through the second bracket and is pivotally connected to the fixed frame. A synchronous transmission belt is sleeved outside the plurality of second movable rollers and the second driving roller, and the second driving roller is in transmission connection with the second driving motor.

[0013] Further, counterweights are provided at the bottom of the feeding ends of the first bracket and the second bracket, and a limiting plate is provided on the fixed frame. When the first bracket or the second bracket is horizontally arranged, the counterweight contacts the limiting plate.

[0014] Further, the beater assembly includes a cotton grabbing beater, a beater motor, a traveling motor, a support, and a slide rail. The two slide rails are symmetrically arranged on the inner walls on both sides of the machine shell. The cotton grabbing beater, the beater motor, and the traveling motor are all arranged on the support. The cotton grabbing beater is in transmission connection with the beater motor. A pulley adapted to the slide rail is provided at the bottom of the support, and the pulley is in transmission connection with the traveling motor.

[0015] Further, a plurality of plate nails are uniformly arranged on the surface of the cotton grabbing beater, and the nail heads of the plate nails penetrate through the holes of the falling cotton grille.

[0016] Further, vertical adjustment holes are provided at both ends of the support, and bearings are connected to both ends of the cotton grabbing beater. The bearings are respectively detachably connected to the vertical adjustment holes.

[0017] As can be seen from the above technical solutions, compared with the prior art, the present invention discloses a wet cotton automatic turnover and disk-taking machine, which has the following advantages:

[0018] 1. It does not require a hydraulic device. Only relying on the displacement of the cotton cake itself along with the synchronous conveyor belt, the wet cotton cake is automatically tilted forward and turned over at the center of the first bracket to complete the disk-taking of the wet cotton cake, saving electricity and fuel, and reducing the failure rate.

[0019] 2. The cotton cake is only automatically turned over twice and falls on the top of the machine shell. Through the barrier at the top of the machine shell, the cotton is grabbed by the cotton grabbing beater inside the machine shell. The grabbed cotton blocks are small and uniform, with a high degree of loosening. While the support moves back and forth along the slide rail, the cotton grabbing beater easily grabs the wet cotton and sends it down, achieving overall average grabbing and good mixing effect, and the loosening is safe and stable.

[0020] 3. The cotton grabbing beater can be adjusted and moved up and down. According to the cotton variety or humidity, the length of the plate nails extending out of the cotton dropping grille holes is adjusted to ensure smooth cotton grabbing and prevent the phenomenon of blockage of the cotton dropping grille holes.
