[0027] refer to Figure 2-Figure 4The connecting parts include a hinge seat 41, a hinge rod 42 and a tension spring 43. The bottom of the lifting plate 4 and the four corners of the top of the kneading plate 5 are fixedly connected with a hinge seat 41. A hinge rod 42 is hinged between the two hinge seats 41 opposite to each other. The upper and lower ends of the hinge rod 42 have a spherical part 44 that cooperates with the hinge seat 41. Four tension springs 43 are fixedly connected between the lifting plate 4 and the kneading plate 5.

The output shaft of the driving motor is connected to the rotating block 51. The bottom of the rotating block 51 is connected to the cam 52. The cam 52 is rotatably connected to the protrusion 53 located in the straight groove 54 at a position deviated from the axis.

[0029] refer to Figure 2 and Figure 5 The high-efficiency cotton kneading device for the production and processing of blended cotton yarn also includes a connecting rod 62 and a second protrusion 63. The rotating plate 6 includes a rotating shaft portion 60, and the rotating plate 6 rotates around the rotating shaft portion 60. A straight hole 61 is opened on the rotating plate 6. The front and rear sides of the left part of the lifting plate 4 are fixedly connected with a connecting rod 62, and the bottom end of the connecting rod 62 is rotatably connected to the second protrusion 63 located in the straight hole 61.

[0030] refer to Figure 2 and Figure 5 The high-efficiency cotton kneading device for the production and processing of blended cotton yarn also includes an adjusting mechanism, which includes a slider 72, a rotating block 73 and an electric push rod 74. A straight hole 71 is opened at one end of the rotating plate 6 away from the rotating shaft portion 60. The rotating plate 6 is provided with a slider 72 that slides along the straight hole 71. The lower electric roller 7 is rotatably connected between the two rotating plates 6, and the upper electric roller 7 is rotatably connected between the two sliders 72. The slider 72 and the rotating plate 6 are rotatably connected with the rotating block 73. The rotating block 73 on the rotating plate 6 is bolted with an electric push rod 74, and the telescopic rod of the electric push rod 74 is fixedly connected to the rotating block 73 on the slider 72.

[0031] The method for adjusting the distance between the two electric rollers 7 is as follows: control the telescopic rod of the electric push rod 74 to extend, the rotating block 2 73 rotates adaptively, the distance between the two rotating blocks 2 73 on the same side increases, and the slider 72 slides upward along the straight hole 2 71, thereby driving the upper electric roller 7 to move upward, and the distance between the two electric rollers 7 increases; then control the telescopic rod of the electric push rod 74 to shorten, conversely, the distance between the two rotating blocks 2 73 on the same side decreases, the slider 72 slides downward along the straight hole 2 71, and the distance between the two electric rollers 7 decreases.

[0032] First, the electric push rod 74 is controlled to increase the distance between the two electric rollers 7 so that the guide cylinder 9 guides the yarn to between the two electric rollers 7, and the electric push rod 74 is controlled to reduce the distance between the two electric rollers 7 to adapt to the thickness of the yarn; then the reduction motor 1 is controlled to drive the electric roller 7 to rotate intermittently, the rotation direction of the upper electric roller 7 is counterclockwise, and the rotation direction of the lower electric roller 7 is clockwise, so that the yarn is transmitted to the conveyor belt 2 through the two electric rollers 7, and the servo motor 1 is controlled to drive the conveyor roller 21 to rotate intermittently, driving the conveyor belt 2 to rotate intermittently, and the conveyor belt 2 intermittently transports the yarn to the right.

[0033] The electric cylinder is controlled to drive the lifting plate 4 to descend, driving the connecting piece, kneading plate 5, rotating drum 50, rotating block 1 51, cam 52, connecting rod 62 and protrusion 2 63 to descend as a whole, so that the rotating drum 50 presses down the yarn on the conveyor belt 2, and the support plate 22 plays a supporting role. At this time, the servo motor 1 and the reduction motor 1 stop working, the electric drum 7, the conveyor roller 21 and the conveyor belt 2 stop rotating, and the driving motor is controlled to drive the rotating block 1 51 to rotate, driving the cam 52 to rotate, and the protrusion 2 63 rotates around the rotating block 1 51. Since the protrusion 1 53 is located in the slot 54, the hinge rod 42 is hinged to the hinge seat 41, and the rotating protrusion 1 53 will continuously push the kneading plate 5. Between the hinge rod 42 and the tension spring 43 Under the cooperation of elastic force, flexible kneading is formed to reduce fiber damage. The spherical part 44 can adaptively rotate on the hinge seat 41, so that the yarn directly below is kneaded through the rotating drum 50 on the kneading plate 5, so that the yarn is further formed into a cotton batting; at the same time, since the second protrusion 63 is located in the straight hole 1 61, the descending protrusion 2 63 will push the rotating plate 6 to rotate upward with the rotating shaft part 60 as the axis, driving the two electric rollers 7 to rotate with the rotating shaft part 60 as the axis. The electric roller 7 is located at a higher position, and the yarn on the left side of the electric roller 7 can adaptively droop a distance, so that the subsequent yarn has sufficient temporary storage space to avoid yarn entanglement. There is no need to stop the feeding of the yarn, and the purpose of continuous feeding of the yarn can be achieved.

[0034] When the kneading process of this part of the yarn is completed, the electric cylinder, lifting plate 4, connecting piece, kneading plate 5, rotating drum 50, rotating block 1 51, cam 52, connecting rod 62 and protrusion 2 63 are controlled to rise as a whole. The rising protrusion 2 63 pushes the rotating plate 6 to rotate downward and reset with the rotating shaft part 60 as the axis, driving the electric roller 7 to reset to the initial position, and controlling the reduction motor 1 to drive the electric roller 7 to rotate again. At the same time, controlling the servo motor 1 to make the conveyor belt 2 rotate again, and conveying the next part of the yarn to the bottom of the kneading plate 5. Similarly, the kneading plate 5 kneads again, and the collecting frame 23 scrapes off a small amount of cotton wool that falls on the surface of the lower half of the conveyor belt 2, reducing the influence of the cotton wool on subsequent kneading. In this way, the yarn is continuously fed, the electric roller 7 and the conveyor belt 2 automatically feed intermittently, and the rotating drum 50 on the kneading plate 5 kneads intermittently. The process is continuous and the kneading efficiency is improved.

[0035] Implementation method 2: Based on implementation method 1, refer to Figure 1 、 Figure 2 and Figure 6 The efficient cotton kneading device for the production and processing of blended cotton yarn also includes a fixed plate 101, a rotating frame 102 and a flattening cylinder 103. The fixed plate 101 is symmetrically fixedly connected to the front and back of the right side of the workbench 1. A rotating frame 102 driven by a second reduction motor is rotatably connected between the two fixed plates 101, and two symmetrical flattening cylinders 103 are rotatably connected to the rotating frame 102.

[0036] refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8 The high-efficiency cotton kneading device for the production and processing of blended cotton yarn also includes a slitting mechanism, which includes a fixed rod 121, a second guide cylinder 122, a rotating rod 123, a slitting wheel 124, a sliding sleeve 125 and a bolt 126. The right part of the workbench 1 is symmetrically bolted with fixed rods 121 front and back. The lower parts of the two fixed rods 121 are rotatably connected with the second guide cylinder 122. The upper parts of the two fixed rods 121 are rotatably connected with a rotating rod 123 driven by a second servo motor. A row of sliding sleeves 125 are provided on the rotating rod 123. The sliding sleeves 125 are all connected with slitting wheels 124. The sliding sleeves 125 are all threadedly connected with bolts 126 whose ends are in close contact with the surfaces of the rotating rods 123.

[0037] refer to Figure 1 、 Figure 2 and Figure 9 The efficient cotton kneading device for the production and processing of blended cotton yarn also includes a fixed frame 131 and a crushing roller 132. The fixed frame 131 is welded on the right side of the workbench 1, and a pair of crushing rollers 132 driven by a reduction motor 2 are installed in the fixed frame 131.

[0038] By controlling the reduction motor 2 to drive the rotating frame 102 to rotate clockwise, the rotating frame 102 drives the two flattening cylinders 103 to rotate. At the same time, the flattening cylinder 103 can rotate on its own. The rotating flattening cylinder 103 pushes the cotton batt to flatten the cotton batt to prevent it from wrinkling; then the flattened cotton batt passes through the position between the guide cylinder 2 122 and the slitting wheel 124, and the servo motor 2 is controlled to drive the rotating rod 123 and the slitting wheel 124 to rotate together, and the slitting wheel 124 cuts the cotton batt; by loosening the bolt 126, the sliding sleeve 125 can be pushed to slide on the rotating rod 123 to adjust the distance between the two adjacent slitting wheels 124, and then tightening the bolt 126, so that the cotton batt can be cut into cotton batts of different widths according to actual needs. The uneven parts of the front and rear edges of the cotton batt fall between the two crushing rollers 132 for crushing. After crushing, the cotton wool is temporarily stored in the fixed frame 131 for subsequent recycling. Each process is closely coordinated to further improve the continuity and processing efficiency of the process.
