[0002] When a conventional winder winds up an object, the winder roller is limited and pressed against the top of the drive roller, and the drive roller is used to drive the winder roller to rotate, so that the material is continuously wound into the winder roller. The limiting structure of the winder roller is an axial limiting structure, which can only prevent the winder roller from moving in the lateral direction. The winder roller will jump in the vertical direction. During the jumping process, a large amount of gas will be drawn in to form bubbles on the wound product. Especially when the winding speed is high, a large number of bubbles or even sheets of bubbles will be formed on the wound product, affecting the quality of the wound product. Utility Model Content

[0012] The utility model has the following advantages:

[0013] 1. A pressing mechanism for a winding machine according to the utility model, by arranging a transfer structure, a first pressing structure and a second pressing structure. When winding, the transfer structure is used to transfer and move the winding roller to the positions of the first pressing structure and the second pressing structure.

Since the first swinging block and the second swinging block are respectively on one side of the winding roller, the first swinging block and the second swinging block can limit the vertical direction of the winding roller after abutting against the winding roller, thereby effectively reducing the jumping of the winding roller during winding, reducing the air entering the material, and ensuring the quality of the winding finished product.

[0014] 2. The pressing mechanism of the utility model, by arranging the first fixing block and the second adjusting block, can quickly position and install the first limiting block by using the first mounting holes of the first fixing block. The installation position of the second limiting block can be quickly adjusted through the second mounting holes of the second adjusting block, so as to adapt to winding rollers and materials of different processes, and increase the applicability of the pressing mechanism.

[0027] Referring to Figure 1 and Figure 2 , a pressing mechanism for a winding machine, is disposed at both ends in the width direction of the winding device 01, and includes a transfer structure 1 for supporting the winding roller 012, a first pressing structure 2 and a second pressing structure 3. When the pressing mechanism operates, the transfer structure 1 drives the winding roller 012 to move to the first pressing structure 2 and the second pressing structure 3, and then the first pressing structure 2 and the second pressing structure 3 approach the winding roller 012 and press against the winding roller 012. The first pressing structure 2 and the second pressing structure 3 form an enclosing limit for the winding roller 012, so as to prevent the winding roller 012 from jumping in the vertical direction, thereby ensuring the winding quality.

[0028] Specifically, the winding device 01 has a driving roller 011. After the transfer structure 1 drives the winding roller 012 to move into place, the winding roller 012 will abut against the driving roller 011. The transfer structure 1 includes a transfer fixing seat 11 provided on the winding device 01, a sliding component 12 slidably connected to the transfer fixing seat 11, and a lifting support component 13 provided on the sliding component 12. The transfer fixing seat 11 is fixedly connected to the outside of the winding device 01. The transfer fixing seat 11 extends along the length direction of the winding device 01. The sliding component 12 includes a transfer guide rail 121 provided on the transfer fixing seat 11, a transfer sliding seat 122 slidably connected to the transfer guide rail 121, and a sliding drive member 123 for driving the transfer sliding seat 122. The transfer guide rail 121 is laid along the length direction of the transfer fixing seat 11. The transfer sliding seat 122 is in an "L" shape. One end of the transfer sliding seat 122 is slidably connected to the transfer guide rail 121, and the other end of the transfer sliding seat 122 passes through the winding device 01 and is located inside the winding device 01. The winding device 01 is provided with a chute for cooperating with the transfer sliding seat 122. The sliding drive member 123 is fixed to the outside of the winding device 01. The sliding drive member 123 is a cylinder. Under the drive of the sliding drive member 123, the transfer sliding seat 122 reciprocates along the length direction of the transfer guide rail 121.

[0029] Referring to Figure 2 , Figure 3 and Figure 4 , the lifting support component 13 includes a lifting drive member 131 provided on the transfer sliding seat 122 and a transfer support member 132 provided on the lifting drive member 131. The transfer support member 132 has a support groove 1321 for supporting the winding roller 012. The lifting drive member 131 is fixed to the transfer sliding seat 122. The lifting drive member 131 is a cylinder. The output end of the lifting drive member 131 faces vertically downward. The transfer support member 132 is arranged at the output end of the lifting drive member 131. The support groove 1321 has an opening for cooperating to fit the winding roller 012.

[0030] The first pressing structure 2 includes a first swing block 21 rotatably connected to the driving roller 011 and a first driving component 22 for driving the first swing block 21. In this embodiment, the first swing block 21 is a rotating block sleeved outside the driving roller 011. The first swing block 21 rotates independently of the driving roller 011. The side of the first swing block 21 faces the winding roller 012. In this embodiment, the first driving component 22 includes a first driving cylinder 221 hinged to the driving roller 011. A first connecting block 222 is arranged at the output end of the first driving cylinder 221. The first connecting block 222 is a hinge seat. The first connecting block 222 is rotatably connected to the first swing block 21. Under the drive of the first driving component 22, the first swing block 21 abuts against or disengages from the winding roller 012.

[0031] In order to quickly limit the winding roller 012, the first swing block 21 is provided with a first limiting block 211. The first limiting block 211 is provided with a first limiting groove 2111 facing the winding roller 012, and the first limiting groove 2111 is arranged in an arc shape. When the first swing block 21 moves into place, the first limiting groove 2111 will abut against the winding roller 012 to form a semi-surrounding limit. At the same time, the first pressing structure 2 further includes a first fixing block 23 arranged on the first swing block 21. The first fixing block 23 is provided with a number of first mounting holes, and the first limiting block 211 is connected to one of the first mounting holes.

[0032] Similarly, the second pressing structure 3 includes a second swing block 31 rotatably connected to the driving roller 011 and a second driving assembly 32 for driving the second swing block 31. The second swing block 31 faces the other side of the winding roller 012, and the second swing block 31 abuts against or disengages from the winding roller 012. The second swing block 31 is a rotating block sleeved outside the driving roller 011, and the second swing block 31 rotates independently of the driving roller 011. The second swing block 31 is provided with a second limiting block 311. The second limiting block 311 is provided with a second limiting groove 3111 facing the winding roller 012. The second limiting groove 3111 has a straight portion and an arc portion. When the second swing block 31 moves into place, the straight portion and the arc portion of the second limiting groove 3111 will abut against the winding roller 012 to form the other part of the semi-surrounding limit.

[0033] The second driving assembly 32 includes a second driving cylinder 321 hinged to the winding device 01. The output end of the second driving cylinder 321 is provided with a second connecting block 322, and the second connecting block 322 is connected to the second swing block 31. It is worth mentioning that the second pressing structure 3 further includes a second adjusting block 33 arranged on the second swing block 31. The second adjusting block 33 is provided with a number of second mounting holes, and the second limiting block 311 is connected to the second mounting holes. The position of the second limiting block 311 can be adjusted through the second adjusting block 33, so as to adjust the distance between the second limiting block 311 and the winding roller 012 to adapt to the winding roller 012 of different processes.

[0034] In order to limit the winding roller 012 in the horizontal direction, a number of limiting bearings are arranged on the winding roller 012, and a number of limiting bearings form a limiting groove. When the pressing mechanism operates, the first pressing structure 2 and the second pressing structure 3 approach the winding roller 012 simultaneously. The first limiting block 211 and the second limiting block 311 are buckled into the limiting groove to limit the winding roller 012 in the horizontal direction. At the same time, the first limiting block 211 and the second limiting block 311 form an enclosing limit to prevent the winding roller 012 from jumping in the vertical direction and ensure the winding quality.
