A feeding roller 103 and a winding roller 104 are respectively rotatably connected between the two sets of struts 102. A motor 112 is fixedly installed on one side of the struts 102. The output end of the motor 112 is fixedly connected to one end of the winding roller 104. A fabric roll is sleeved on the outer wall of the feeding roller 103, and one end of the fabric is fixedly installed on the outer wall of the winding roller 104. The motor 112 is used to drive the winding roller 104 to rotate, and the fabric pulls the feeding roller 103 to rotate, so as to unroll the fabric roll sleeved on its outer wall; A guide roller 106 is rotatably connected inside the impregnation tank 105.

[0026] Working principle: When the device is in use, first, two groups of struts 102 are fixedly installed on the top of the support base plate 101. A feeding roller 103 and a winding roller 104 are rotatably connected between the two groups of struts 102 respectively. A motor 112 is fixedly installed on one side of the strut 102. The output end of the motor 112 is fixedly connected to one end of the winding roller 104. A fabric roll is sleeved on the outer wall of the feeding roller 103, and one end of the fabric is fixedly installed on the outer wall of the winding roller 104. The motor 112 is used to drive the winding roller 104 to rotate, and the fabric pulls the feeding roller 103 to rotate, so as to unroll the fabric roll sleeved on its outer wall. Secondly, an impregnating tank 105 and two brackets 201 are fixedly installed on the top of the support base plate 101. A second telescopic rod 202 is inserted through the inside of the two brackets 201. An installation base 203 is fixedly connected to the telescopic end of a group of second telescopic rods 202, and a clamping plate 205 is fixedly connected to the telescopic end of the other group of second telescopic rods 202. A heating roller 204 is rotatably connected inside the installation base 203. A clamping seat 206 is fixedly installed on the bottom inner wall of the impregnating tank 105. Card slots 207 are opened on both sides of the clamping seat 206. It is set that the card slots 207 are clamped with the clamping plate 205. The fabric is arranged on the bottom outer wall of the heating roller 204. The second telescopic rod 202 is used to extend, so as to press the fabric into the impregnating tank 105. The heating roller 204 is used to heat the surface of the fabric, which is convenient for better absorption of resin. Then, the fabric is arranged between the clamping plate 205 and the clamping seat 206. The second telescopic rod 202 is used to drive the clamping plate 205 to be clamped with the card slot 207, so as to form a slit between the clamping plate 205 and the clamping seat 206. The fabric passes through the narrow slit, forcing the resin to fully infiltrate the fibers under the action of pressure, which is convenient for improving the uniformity of resin distribution and the stability of prepreg. Then, a guiding roller 106 is rotatably connected inside the impregnating tank 105. The fabric passing through the clamping plate 205 and the clamping seat 206 is sleeved in an S shape between a group of guiding rollers 106. A collecting tank 107 is fixedly communicated with one side of the impregnating tank 105. A guiding plate 108 is fixedly installed on the bottom inner wall of the collecting tank 107. A filter screen 109 is fixedly installed on the top of the collecting tank 107. A group of first telescopic rods 110 are respectively installed on both sides of the collecting tank 107. A pressing roller 111 is rotatably connected inside the group of first telescopic rods 110. The length of the first telescopic rod 110 is adjusted, and the pressing roller 111 is arranged on the top of the fabric. When the winding roller 104 drags the fabric, the pressing roller 111 is driven to rotate on the top of the fabric, so as to extrude the excess resin on the surface of the fabric. The resin falls into the collecting tank 107 through the filter screen 109, and then flows into the impregnating tank 105 through the guiding plate 108, avoiding waste of resin and reducing the cost of raw materials to a certain extent.
