[0024] In addition, the top and bottom of the winding column 2 are provided with No. 2 guide grooves 202, the interiors of the two No. 2 guide grooves 202 are slidably connected with two No. 2 guide blocks 208, the outward faces of each No. 2 guide block 208 are fixedly connected with straight plates 209, the interiors of each No. 2 guide groove 202 are fixedly connected with guide columns 203, the opposite No. 2 guide blocks 208 are fixedly connected with return springs 204, the return springs 204 are sleeved on the exteriors of the guide columns 203, the bottoms of one side of the straight plates 209 are fixedly connected with the tops of the No. 2 guide blocks 208 through triangular reinforcing ribs 2010, the opposite faces of the two straight plates 209 are provided with cavities, the interiors of the cavities are fixedly connected with connecting columns 2011, the exteriors of the connecting columns 2011 are slidably connected with expansion plates 2013, the bottoms of the expansion plates 2013 are fixedly connected with the bottoms of the cavities through tight springs 2012, the tight springs 2012 are sleeved on the exteriors of the connecting columns 2011, the ends of the opposite expansion plates 2013 are fixedly connected with side hooks 2014, when the silk screen is not started to be wound or is in a relaxed state, the two No. 2 guide blocks 208 are kept on the opposite sides of the No. 2 guide grooves 202 due to the elastic force of the return springs 204 and are in an open state. At this time, the straight plates 209, the expansion plates 2013 and the side hooks 2014 thereon are also in an open state. When the silk screen is started to be wound on the winding column 2, the tension of the silk screen will gradually increase. With the increase of the tension, the straight plates 209 will be subjected to inward pressure, causing the No. 2 guide blocks 208 to slide inward in the No. 2 guide grooves 202 and compress the return springs 204. With the inward movement of the straight plates 209, the expansion plates 2013 will expand outward under the elastic force of the tight springs 2012 to increase the contact area with the silk screen. At the same time, the side hooks 2014 will also move outward with the expansion of the expansion plates 2013 and hook the edges of the silk screen to further fix the position of the silk screen. With the continuous winding of the silk screen, the above process is repeated. Whenever the tension of the silk screen increases, the straight plates 209 will move inward, and the expansion plates 2013 and the side hooks 2014 will also expand outward correspondingly to ensure that the silk screen is always firmly fixed on the winding column 2. By arranging the No. 2 guide grooves 202, the No. 2 guide blocks 208, the straight plates 209, the expansion plates 2013 and the side hooks 2014, the fixing effect of the silk screen is further enhanced. Even when the tension of the silk screen is large or subjected to external force impact, the silk screen can always be firmly fixed on the winding column 2, avoiding the falling or displacement of the silk screen. Since the expansion plates 2013 and the side hooks 2014 can automatically adjust the position and shape according to the tension of the silk screen, the silk screen can always maintain a tight and orderly state during the winding process. This not only improves the winding quality but also provides a better basis for subsequent production of silk screen printing plates. The triangular reinforcing ribs 2010 not only increase the structural strength of the straight plates 209 but also improve the stability and durability of the entire device.This makes the device can withstand greater tension and impact force, prolong the service life, although the second guide groove 202 and its related structure is increased, but the overall structure of the utility model still keeps simple and clear. The connection and cooperation mode between the parts are reasonable and reliable, so that the adjustment and maintenance of the device become very convenient.

[0025] It should be noted that the drive of the winding column 2 is a prior art, so it is not described in detail.

[0026] The working principle and use process of the utility model are as follows: firstly, when not starting to wind the wire mesh, two first guide blocks 205 are kept on the opposite sides of the first guide slot 201 due to the elastic force of the reset spring 204, and are in the open state, when it is needed to wind the wire mesh on the winding column 2, firstly, the starting end of the wire mesh is passed through the limiting hook 207, and starts to wind along the surface of the winding column 2. Due to the existence of the limiting hook 207, the starting end of the wire mesh is fixed on the winding column 2 firmly, and the slippage phenomenon in the initial winding is avoided, with the continuous winding of the wire mesh, the edge of the wire mesh will gradually contact the first guide block 205. Since the first guide block 205 can slide on the guide column 203, and is subjected to the elastic force of the reset spring 204, they will automatically adjust the position according to the width of the wire mesh, and ensure that the limiting hook 207 can always hook the edge of the wire mesh. In this way, even if the wire mesh is subjected to certain tension or external force in the winding process, it can also be fixed by the fixing action of the limiting hook 207, to avoid relative movement with the winding column 2, to ensure the close winding of the wire mesh, with the continuous winding of the wire mesh, the above process is repeated continuously until the required winding length or thickness is reached, by arranging the first guide slot 201, the first guide block 205, the bottom plate 206 and the limiting hook 207 and other structures, the utility model effectively solves the problem that the wire mesh and the winding column 2 are prone to relative movement in the prior art, so that the wire mesh can be closely and orderly wound on the winding column 2, thereby improving the winding efficiency, the cooperation of the guide column 203 and the reset spring 204 enables the first guide block 205 to automatically adjust the position according to the width of the wire mesh, and enhances the stability and adaptability of the device. This design is not only suitable for wire meshes of different widths, but also can maintain the stability of the wire mesh during the winding process, to avoid its falling off or displacement due to external force or vibration, when not starting to wind the wire mesh or the wire mesh is in a relaxed state, two second guide blocks 208 are kept on the opposite sides of the second guide slot 202 due to the elastic force of the reset spring 204, and are in the open state. At this time, the straight plate 209 and the expansion plate 2013 and the side hook 2014 thereon are also in the relatively open state, when the wire mesh starts to be wound on the winding column 2, the tension of the wire mesh will gradually increase. With the increase of the tension, the straight plate 209 will be subjected to inward pressure, causing the second guide block 208 to slide inward in the second guide slot 202 and compress the reset spring 204, with the inward movement of the straight plate 209, the expansion plate 2013 will expand outward under the elastic force of the tight spring 2012, to increase the contact area with the wire mesh. At the same time, the side hook 2014 will also move outward with the expansion of the expansion plate 2013, to hook the edge of the wire mesh, to further fix the position of the wire mesh, with the continuous winding of the wire mesh, the above process is repeated continuously. Whenever the tension of the wire mesh increases, the straight plate 209 will move inward, and the expansion plate 2013 and the side hook 2014 will also expand outward accordingly, to ensure that the wire mesh is always fixed on the winding column 2 firmly.
