The ends of the upper pressing roller 12 and the lower pressing roller 11 are both provided with a first motor to drive the upper pressing roller 12 and the lower pressing roller 11 to rotate at a uniform speed in opposite directions.

[0034] The collecting tank 14 with an opening is located at the bottom of the lower pressing roller 11, and the collecting tank 14 is detachably connected to the frame 1 by bolts, and the collecting tank 14 is used to collect liquid dripping from the cotton fabric. The drying roller 13 is located on one side of the upper pressing roller 12, and a second motor is installed on the drying roller 13 to drive the drying roller 13 to rotate.

[0035] Reference Figure 2 and Figure 3 , a connecting member 5, an abutment plate 43, a slider 45 and a pusher 6 are installed on the horizontal plate 41. There are two connecting members 5, and the two connecting members 5 are respectively located on both sides of the horizontal plate 41. Each connecting member 5 includes a support frame 51, a vertical rod 52, a connecting plate 53 and a spring 54. The two support frames 51 are respectively located on both sides of the horizontal plate 41. Each vertically arranged support frame 51 is L-shaped. The bottom of each support frame 51 contacts the top of the horizontal plate 41, and the side wall of each support frame 51 is used to contact the side wall of the cotton fabric. The horizontally arranged abutment plate 43 is located on the top of the cotton fabric, and the bottom of the abutment plate 43 contacts the top of the cotton fabric. The side wall of the abutment groove 44 is horizontally provided with an abutment groove 44. There are two abutment grooves 44, and the two abutment grooves 44 are respectively located on both sides of the abutment plate 43. The vertical rod 52 is located at the top of the support frame 51, and one end of the vertical rod 52 passes through the support frame 51 and is fixedly connected to the connecting plate 53.

[0036] There are two sliders 45 and two pushers 6, and each slider 45 and each pusher 6 corresponds to each support frame 51. Each slider 45 is T-shaped, and the top of each slider 45 is fixedly connected to the bottom of the support frame 51. The bottom of each slider 45 extends into the slide groove 42 and contacts the side wall of the slide groove 42. The pusher 6 includes a screw rod 61 and a hand wheel 62. One end of the horizontally arranged screw rod 61 is threadedly inserted into the frame 1 and then rotatably connected to the side wall of the support frame 51. The other end of the screw rod 61 is circumferentially fixedly connected to the hand wheel 62. The vertically arranged hand wheel 62 is provided with anti-slip grooves.

[0037] When the cotton fabric passes through the gap between the abutment plate 43 and the cross plate 41, the bottom of the abutment plate 43 contacts the top of the cotton fabric, and the top of the cross plate 41 contacts the bottom of the cotton fabric, making it difficult for the cotton fabric to wrinkle, thereby improving the drying effect of the drying roller 13. When processing cotton fabrics of different thicknesses, through the elastic potential energy of the spring 54, the vertical rod 52 is lifted and lowered to drive the connecting plate 53 and the abutment plate 43 to lift and lower synchronously, so that the abutment plate 43 is always in contact with the top of the cotton fabric, so that the cotton fabric is not easy to wrinkle. When processing cotton fabrics of different widths, the staff rotates the hand wheel 62, thereby driving the two to rotate synchronously, so that the two support frames 51 move in a direction close to or away from each other until the support frame 51 moves to the set position, so that the side wall of the support frame 51 contacts the side wall of the cotton fabric, so that the cotton fabric is not easy to deflect, and at the same time, it can adapt to cotton fabrics of different widths.

[0038] Reference Figure 2 and Figure 3 Two lifting devices 2 are installed at the end of the lower pressure roller 11, and the two lifting devices 2 are respectively located at the two ends of the lower pressure roller 11, and each lifting device 2 includes a driving source 22 and a lifting block 21. The driving source 22 includes a cylinder 221 and a lifting rod 222. The cylinder 221 is located on the frame 1, and the cylinder body of the cylinder 221 is fixedly connected to the frame 1. The piston rod of the cylinder 221 is vertically arranged upward, and the piston rod of the cylinder 221 is coaxially fixedly connected to the lifting rod 222. The top of the vertically arranged lifting rod 222 is connected to the bottom of the lifting block 21.

[0039] The horizontally arranged lifting block 21 is located below the lower pressure roller 11, and a lifting groove 31 is horizontally opened on the side wall of the lifting block 21. The lifting groove 31 is arc-shaped, and the concave arc side opening of the lifting groove 31 is vertically upward. The side wall of the lifting groove 31 is used to contact the end of the lower pressure roller 11. A plurality of balls 32 are installed on the side wall of the lifting groove 31. The plurality of balls 32 are evenly distributed along the circumference of the lifting groove 31. One side of each ball 32 is rotatably connected to the side wall of the lifting groove 31, and the other side of each ball 32 contacts the end of the lower pressure roller 11, thereby reducing wear and extending the service life of the lifting block 21.

[0040] When the cotton fabric passes through the gap between the upper pressing roller 12 and the lower pressing roller 11, the upper pressing roller 12 and the lower pressing roller 11 squeeze the cotton fabric, so that the moisture on the fabric is separated from the cotton fabric, thereby reducing the moisture on the cotton fabric, thereby reducing the time required for the drying roller 13 to dry the cotton fabric, and improving work efficiency. When processing cotton fabrics of different thicknesses, the staff starts the cylinder 221, and the piston rod of the cylinder 221 lifts and lowers the lifting block 21 synchronously to contact the end of the lower pressing roller 11 through the lifting groove 31 on the lifting block 21, thereby driving the lower pressing roller 11 to lift and lower synchronously, and then adjusting the distance between the lower pressing roller 11 and the upper pressing roller 12, so as to adapt to cotton fabrics of different thicknesses and expand the scope of use.

[0041] The implementation principle of a cotton fabric drying machine in an embodiment of the present application is as follows: when the cotton fabric is processed, the staff transfers the cotton fabric to the transverse plate 41, and the cotton fabric passes through the gap between the abutment plate 43 and the transverse plate 41. The cotton fabric is not easy to wrinkle by the abutment plate 43. The staff rotates the hand wheel 62, and the rotation of the hand wheel 62 drives the screw 61 to rotate synchronously. Through the slider 45 and the slide groove 42, the support frame 51 moves in the horizontal direction until the side wall of the abutment plate 43 contacts the side wall of the cotton fabric, so that the cotton fabric is not easy to deflect. Then the cotton fabric is transferred to the gap between the upper pressing roller 12 and the lower pressing roller 11. Through the squeezing effect of the upper pressing roller 12 and the lower pressing roller 11, the moisture on the cotton fabric is separated from the cotton fabric, thereby reducing the moisture on the cotton fabric, and then reducing the time required for the drying roller 13 to dry the cotton fabric, thereby improving production efficiency.

[0042] When processing cotton fabrics of different thicknesses, when the cotton fabrics pass through the gap between the horizontal plate 41 and the abutment plate 43, the vertical rod 52 drives the connecting plate 53 and the abutment plate 43 to rise and fall in the vertical direction through the elastic potential energy of the spring 54, so as to adapt to cotton fabrics of different thicknesses. At the same time, the staff starts the cylinder 221, and the lifting and lowering of the piston rod of the cylinder 221 drives the lifting rod 222 to rise and fall synchronously, thereby driving the lifting block 21 to rise and fall synchronously, and the side wall of the lifting groove 31 contacts the end of the lower pressure roller 11, so that the lower pressure roller 11 rises and falls synchronously with the lifting block 21, so as to adapt to cotton fabrics of synchronous thickness, further expanding the scope of use.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
