Increasing the roughness can also ensure the adhesion effect of the chemical coating in the subsequent spraying process.

[0039] like Figure 8 As shown, in order to adapt to knitted fabrics of various materials, the sanding frame 44 is made of elastic material, and an air pipe 45 is installed on the sanding frame 44. The air pipe 45 is arranged parallel to the connecting frame 41, and one end of the air pipe 45 is connected to a plurality of expansion tubes 451, and the expansion tubes 451 are connected to the air pipe 45.

A driving ring 52 is provided for rotation outside the positioning sleeve rod 51, and a servo motor is installed inside the positioning sleeve rod 51 to drive the driving ring 52 to rotate. Positioning rings 53 are installed at both ends of the driving ring 52;

[0041] A pair of air inlet grooves 56 are provided on the positioning ring 53, and a plurality of arc-shaped fan blades 561 are installed on the inner wall of the positioning ring 53. A rubber ring 531 is clamped at one end of the positioning ring 53. The driving ring 52 can rotate, and cooperate with the compression ring 43 to push the reset slide bar 42 to move, and the reset slide bar 42 can be reset under the action of the elastic rod, thereby driving the bottom sanding frame 44 to reciprocate as a whole, and can perform sanding treatment on the surface of the knitted fabric. In addition, as the driving ring 52 rotates, it can cooperate with the arc-shaped fan blades 561 to pour the diffused dust and debris into the air inlet groove 56, and transmit it to the outside of the dust suction plug 54, thereby reducing the diffusion of dust.

[0042] like Figure 6 As shown, in order to reduce the clogging during the dust collection process, a pair of dust collection plug rods 54 are clamped on the positioning frame 5, and the dust collection plug rods 54 have a "C"-shaped cross section. The dust collection plug rods 54 are symmetrically arranged at both ends of the positioning sleeve rod 51, and docking blocks 57 are installed at both ends of the positioning sleeve rod 51. The dust collection plug rods 54 are clamped on the docking blocks 54;

[0043] A clamping plate 55 is installed at one end of the dust suction plug rod 54 for auxiliary limiting. Transmission holes are provided on the clamping plate 55 and the dust suction plug rod 54. The dust suction plug rod 54 is hollow. A plurality of arc grooves are provided on the surface of the dust suction plug rod 54.

At the same time, the rubber ring 531 at one end of the positioning ring 53 can be squeezed between the elastic shaft 541, and the elastic shaft 541 can be toggled to cause a certain amplitude of twisting during the dust suction process, so that the dust adhering to the surface of the dust suction plug rod 54 can be toggled and squeezed, so that it enters the dust suction plug rod 54 along the air flow, and cooperates with each other to dynamically filter the dust, which has a good dust suction effect.

[0044] Working principle: First, when the knitted fabric needs to be processed, it can be transmitted on the transmission frame 2, and the knitted fabric can be clamped at the bottom of the connecting frame 41 by the cooperation of the guide frame 4, which can play a role of limiting. During the rotation of the driving ring 52, the compression ring 43 on one side of the reset slide bar 42 can, under the cooperation of the driving ring 52, push the reset slide bar 42 and the bottom sanding frame 44 to move as a whole, so as to perform sanding treatment on the surface of the knitted fabric, so as to facilitate the subsequent adhesion of chemical coatings, and under the cooperation of the spray plate 32 and the hot air blower inside the spray chamber 3, the processing quality of the equipment can be guaranteed, and along with the sanding pretreatment process, when the surface of the knitted fabric needs to be sanded, the airflow entering the air pipe 45 can be adjusted according to different materials, and the expansion tube 451 can be driven to move axially under the action of air pressure, thereby driving the sanding frame 44 to deform as a whole, so that the sanding plate 461 at the bottom can be attached to the surface of the knitted fabric, which has good applicability;

[0045] Then the driving ring 52 can rotate, and the compression ring 43 can be cooperated to push the reset slide bar 42 to move, and the reset slide bar 42 can be reset under the action of the elastic rod, thereby driving the bottom sanding frame 44 to reciprocate as a whole, and the surface of the knitted fabric can be sanded. In addition, as the driving ring 52 rotates, the arc-shaped fan blades 561 can be cooperated to pour the diffused dust and debris along the air inlet groove 56 and transmit it to the outside of the dust suction plug rod 54. The dust suction plug rod 54 can be connected to the external air pressure pipe and can play a dust suction role under the action of negative pressure. At the same time, the rubber ring 531 at one end of the positioning ring 53 can be squeezed between the elastic shaft 541, and the elastic shaft 541 can be toggled to cause a certain amplitude of twisting during the dust suction process, so that the dust adhering to the surface of the dust suction plug rod 54 can be toggled and squeezed, so that it enters the dust suction plug rod 54 along the air flow, and cooperates with each other to dynamically filter the dust, which has a good dust suction effect.

[0046] Finally, after the fabric enters the spray chamber 3, the transmission shaft 33 can be moved to transport the spray plate 32 to the top of the knitted fabric, and its surface can be sprayed. The wear-resistant agent is sprayed at a pressure of 0.3MPa, and the amount can be adjusted according to the fabric of different materials. The excess chemical substances can be absorbed by the adsorption shaft to reduce the excess paint dripping on the surface of the knitted fabric.
