When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiment.

[0037] See also Figures 1 to 6 In an embodiment of the present invention, a polytetrafluoroethylene expansion sealing tape winding device includes an operating table 1 and a bracket 2 provided on the operating table 1, wherein the bracket 2 is provided with a winding assembly, and the winding assembly can wind the sealing tape;

[0038] The operating table 1 is provided with a tensioning assembly, which cooperates with the winding assembly so that the sealing tape is always kept in a taut state during the winding process of the sealing tape;

[0039] A reciprocating translation assembly is provided on the operating table 1 and between the bracket 2 and the tensioning assembly. When the reciprocating translation assembly is in operation, the sealing tape can be evenly wound around the winding assembly.

[0040] A transmission structure is provided between the reciprocating translation assembly and the winding assembly. During the operation of the winding assembly, the reciprocating translation assembly will follow the winding assembly through the transmission structure to move.

[0041] In this solution, through the mutual cooperation between the tensioning component and the winding component, the polytetrafluoroethylene expansion sealing tape can be tightly wound to avoid looseness, and during the operation of the winding component, the reciprocating translation component will follow the winding component through the transmission structure to make the polytetrafluoroethylene expansion sealing tape evenly wound on the winding component, thereby solving the problem of uneven winding and unsightly winding of the polytetrafluoroethylene expansion sealing tape.

[0042] As a further solution of the present invention, the winding assembly includes a reel 3 horizontally rotatably arranged on the bracket 2 and a motor 4 installed on the bracket 2, and the output end of the motor 4 is connected to one end of the reel 3.

[0043] In this embodiment, when in use, the end of the polytetrafluoroethylene expansion sealing tape is first fixed to the outer wall of the reel 3. Since one end of the reel 3 is connected to the output end of the motor 4, when the motor 4 is started, the reel 3 will rotate following the output end of the motor 4, thereby winding the polytetrafluoroethylene expansion sealing tape.

[0044] As a further solution of the present invention, the reciprocating translation assembly includes a fixed frame 5 provided on the operating table 1 and a guide rod 6 horizontally provided on the fixed frame 5, and a movable plate 7 is horizontally slidably provided on the guide rod 6;

[0045] An L-shaped rod 8 is provided on one side of the movable plate 7 , a frame plate 9 is provided at one end of the L-shaped rod 8 , two rollers 10 are provided inside the frame plate 9 for horizontal rotation, and the two rollers 10 are vertically symmetrically arranged.

[0046] In this embodiment, before the end of the polytetrafluoroethylene expansion sealing tape is fixed to the outer wall of the drum 3, the polytetrafluoroethylene expansion sealing tape is first passed between the two rollers 10;

[0047] Since the two rollers 10 and the frame plate 9 are slidably arranged on the guide rod 6 through the L-shaped rod 8 and the movable plate 7, when the movable plate 7 moves horizontally back and forth on the guide rod 6 and the reel 3 rotates, the two rollers 10 will cooperate with the frame plate 9 to make the polytetrafluoroethylene expansion sealing tape evenly wound on the reel 3.

[0048] As a further solution of the present invention, a horizontal plate 11 is provided on the fixing frame 5, and two ends of the horizontal plate 11 are respectively provided with a first rotating shaft 12 and a second rotating shaft 13 for horizontal rotation;

[0049] A first sprocket 14 and a second sprocket 15 are respectively provided at one end of the first rotating shaft 12 and the second rotating shaft 13 , and the first sprocket 14 and the second sprocket 15 are connected by a chain 16 ;

[0050] A T-shaped slot 17 is vertically provided on the other side of the movable plate 7 , and a T-shaped rotating rod 18 is horizontally rotatably provided on one of the links of the chain 16 . The T-shaped rotating rod 18 is located in the T-shaped slot 17 and slides with each other.

[0051] In this embodiment, since the T-shaped rotating rod 18 is located in the T-shaped sliding groove 17 and slides with each other, and the T-shaped rotating rod 18 is horizontally rotatably connected to one of the links on the chain 16, when the chain 16 rotates, the movable plate 7 will cooperate with the T-shaped rotating rod 18 through the T-shaped sliding groove 17 and perform horizontal reciprocating movement on the guide rod 6;

[0052] Because the chain 16 is mounted on the first sprocket 14 and the second sprocket 15 , when the first sprocket 14 on the first rotating shaft 12 rotates, the chain 16 and the second sprocket 15 will rotate synchronously therewith.

[0053] As a further solution of the present invention, the transmission structure includes a first bevel gear 19 provided at the other end of the first rotating shaft 12 and a special-shaped rod 20 provided on the fixing frame 5, a transmission rod 21 is provided on the special-shaped rod 20 for horizontal rotation, and a second bevel gear 22 is provided at one end of the transmission rod 21 which is meshed with the first bevel gear 19;

[0054] A driven wheel 23 is provided at the other end of the transmission rod 21 , and a driving wheel 24 is provided at the other end of the reel 3 . The driven wheel 23 and the driving wheel 24 are connected by a belt 25 .

[0055] In this embodiment, since the first bevel gear 19 and the second bevel gear 22 are meshed with each other, when the transmission rod 21 drives the second bevel gear 22 to rotate, the first bevel gear 19 will rotate along with the second bevel gear 22 and drive the first rotating shaft 12 to rotate synchronously;

[0056] Because the driven wheel 23 and the driving wheel 24 are connected by the belt 25, when the reel 3 rotates, the driving wheel 24 will drive the driven wheel 23 to rotate through the belt 25, so that the transmission rod 21 rotates.

[0057] As a further solution of the present invention, the tensioning assembly includes a support base 26 provided on the operating table 1 and two pressing rollers 27 respectively provided on the support base 26 for horizontal rotation, and the two pressing rollers 27 are vertically symmetrically provided.

[0058] In this embodiment, two pressing rollers 27 are used to keep the polytetrafluoroethylene expansion sealing tape between the reel 3 and the pressing roller 27 in a tight state at all times, thereby preventing the polytetrafluoroethylene expansion sealing tape wound on the reel 3 from being loose.
