Abstract
Description
Technical Field
[0001] This utility model relates to the field of PET polyester sheet production technology, and in particular to a PET polyester sheet winding machine. Background Technology
[0002] An adjustable tension PET polyester sheet processing winding machine, with publication number CN 221916563 U, is described. It comprises a PET polyester sheet positioning roller, a limiting roller, an assembly plate, a drive motor, a mounting plate, pulleys, a PET polyester sheet winding roller, and a fixing plate. The PET polyester sheet passes through the gap between the positioning roller and the limiting roller. The positioning roller and the limiting roller fix the feeding position of the PET polyester sheet, preventing it from falling off and improving feeding stability. The sheet is then wound onto the surface of the PET polyester sheet winding roller via a fixing frame mechanism. The PET polyester sheet take-up roller can be quickly assembled and disassembled by connecting the fixed plate to the mounting plates on both sides with bolts. The drive motor can drive the upper mounting plate to rotate, which in turn drives the front mounting plate to rotate through the PET polyester sheet take-up roller. Through the belt pulley drive, the lower mounting plate and the PET polyester sheet take-up roller can rotate synchronously to perform automatic winding. However, the above-mentioned take-up roller requires the fixed plate to be connected to the mounting plates on both sides with bolts for assembly and disassembly, which makes the assembly and disassembly of the take-up roller inconvenient and affects the efficiency of use.

[0024] The present invention will be further described below with reference to the accompanying drawings:
[0025] like Figures 1-6 As shown, a PET polyester sheet winding machine includes a support mechanism, which includes a support box 11 and a base plate 12. The base plate 12 is fixed to one side of the support box 11. The support box 11 is provided with a winding mechanism for intermittently winding PET polyester sheets, and a pressing assembly provided on the support box 11 for pressing the wound PET polyester sheets.
[0026] In this embodiment: the winding mechanism includes a winding assembly, and an intermittent rotating assembly is connected to the rear end of the winding assembly. The winding assembly includes a turntable 21 rotatably mounted on the front wall of the support box 11. Four winding shafts 22 are evenly distributed around the circumference of the turntable 21. The winding shaft 22 located at the front end of the support box 11 is hexagonal prism-shaped. A cavity is provided inside the winding wheel 23 to cooperate with the hexagonal prism of the winding shaft 22. The front end of the winding shaft 22 is threadedly connected to a locking nut 24. By removing the locking nut 24, the winding wheel 23 is sleeved on the winding shaft. 22 enables quick loading and unloading; a large gear 25 is installed on the take-up shaft 22 inside the support box 11, and a take-up wheel 23 is connected to the front side of the take-up shaft 22. A lifting assembly is set at the upper position of the support box 11, and a power shaft 26 is installed on the lifting assembly. A small gear 27 is fixed on the power shaft 26, and a take-up motor 28 is connected to the rear end of the power shaft 26. A circular recessed platform is opened on the inner rear wall of the support box 11 to support the rotation of the take-up shaft 22. The take-up shaft 22 is rotatably connected to the turntable 21 and the support box 11.
[0027] The lifting assembly includes an electric telescopic rod 202 mounted on the upper end of the support box 11, a lifting frame 201 fixed at the lower end of the electric telescopic rod 202, and a power shaft 26 rotatably mounted on the lifting frame 201. The front and rear side walls of the support box 11 are provided with sliding grooves, and a sliding seat supporting the power shaft 26 is provided in the sliding grooves. The power shaft 26 is rotatably connected to the sliding seat. Before the turntable 21 rotates, the electric telescopic rod 202 retracts, causing the lifting frame 201 and the power shaft 26 to move upward as a whole, so that the small gear 27 disengages from the large gear 25. Then, the intermittent rotation assembly drives the rotating shaft 29 to rotate.
[0028] The intermittent rotation assembly includes a rotating shaft 29 fixed at the rear center of the turntable 21 and passing through the support box 11. The rear end of the rotating shaft 29 is provided with a wheel groove 210, and a support shaft 211 is provided on the lower side of the wheel groove 210. A dial wheel 212 that meshes with the wheel groove 210 is mounted on the support shaft 211. A servo motor 213 is connected to the rear end of the support shaft 211. The rotating shaft 29 is rotatably connected to the support box 11. The servo motor 213 drives the dial wheel 212 on the support shaft 211 to rotate, so that the dial wheel 212 dials the wheel groove 210 and the rotating shaft 29 to rotate 90°, thereby switching the winding wheel 23.
[0029] The pressing assembly is provided in two places, located on the uppermost side and the outer side of the winding assembly on the horizontal side, respectively. The pressing assembly includes a fixed frame 31 fixed on the front wall of the support box 11. A guide rod 32 is vertically inserted through the fixed frame 31. A mounting frame 33 is fixed to one end of the guide rod 32 near the winding wheel 23. A pressure roller 34 is rotatably mounted on the mounting frame 33. A spring 35 is sleeved on the outer diameter of the guide rod 32 between the mounting frame 33 and the fixed frame 31. The guide rod 32 is provided in at least two places. The guide rod 32 is slidably connected to the fixed frame 31. During the winding process of the winding wheel 23 winding the PET polyester sheet, the spring 35 pushes the mounting frame 33 and the pressure roller 34 to move towards the winding wheel 23 under the limit of the guide rod 32, so that the pressure roller 34 presses the winding PET polyester sheet to ensure flatness during winding.
[0030] The working principle and usage process of this utility model are as follows: The produced PET polyester sheet is wound onto the uppermost take-up reel 23. The take-up motor 28 drives the power shaft 26 and the pinion 27 to rotate, causing the pinion 27 to mesh with the large gear 25, which in turn drives the take-up shaft 22 and the take-up reel 23 to rotate, thus winding the PET polyester sheet onto the take-up reel 23. At the same time, the pressure roller 34 on the upper side of the take-up reel 23 moves downward under the push of the spring 35 against the mounting bracket 33 and the pressure roller 34, pressing the wound PET polyester sheet. When it is necessary to switch the take-up reel 23, the take-up motor 28 is stopped, and the electric telescopic rod 202 retracts, causing the lifting frame 201 and the power shaft 26 to move upward as a whole, so that the pinion 27 meshes with the large gear 25. After gear 25 disengages, the servo motor 213 drives the actuating wheel 212 on the support shaft 211 to rotate, causing the actuating wheel 212 to rotate the wheel groove 210 and the rotating shaft 29 by 90°, rotating the winding wheel 23 of the PET polyester sheet to a horizontal position. Then, the PET polyester sheet between the pressing components is cut off. The electric telescopic rod 202 extends and pushes the lifting frame 201 and the power shaft 26 to move downward as a whole, so that the small gear 27 meshes with the large gear 25, and continues to wind up the PET polyester sheet. Then, the locking nut 24 on the winding shaft 22 that rotates to the lower side to wind up the PET polyester sheet is removed, and the winding wheel 23 of the PET polyester sheet is pulled out and replaced.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
