Description

Technical Field

[0001] The utility model belongs to the technical field of PETG sheet production, and particularly relates to a winding device for PETG sheet production. Background Art

[0002] PETG material is a transparent plastic. Due to the flexibility of the PETG sheet, it is easy to bend, so the PETG sheet needs to be wound up after production.

[0003] Currently, the Chinese utility model with the publication number CN215592102U discloses a winding machine for PETG sheet production, which includes a fixed bottom plate. Connection plates are arranged inside both ends of the fixed bottom plate. A first motor is installed on the surface of the fixed bottom plate, and the output end of the first motor is connected to the connection plate. A movable bottom plate is arranged on the top side of the connection plate. A sliding groove is formed inside the movable bottom plate. A pneumatic pump is arranged on the bottom side of the movable bottom plate, and the output end of the pneumatic pump extends to the inside of the sliding groove and is provided with a lifting plate. When it is necessary to fix the sheet after winding, the pneumatic pump drives the lifting plate inside the movable bottom plate to lift. When it reaches the sheet, the glue in the glue tank is pumped by a glue pump and then conveyed to the discharge port. Then, the glue is discharged by driving the slider to move left and right through an electric slide rail to make the sheet adhere. And the slider is in a certain arc shape to facilitate gluing with the sheet on the winding shaft.

[0004] The existing winding of PETG sheets generally requires winding them on a special reel. However, the PETG sheet cannot be directly attached to the surface of the reel. Therefore, it is necessary to manually coat one side of the reel surface with glue so that one end of the PETG sheet can be adhered to the reel for winding. However, the existing winding device cannot quickly and evenly coat glue on the surface of the reel, the glue coating area is small, and it is easy to cause the PETG sheet to come off from the reel. And the reel cannot be quickly fixed on the winding device, so the winding efficiency of the PETG sheet is low, reducing the practicability. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a winding device for PETG sheet production, which has the advantages of facilitating the fixation of various different types of reels on the winding device and quickly coating glue on the surface of the reel.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a winding device for PETG sheet production, comprising a support column, a rotating seat is arranged on the top of the support column, four corners inside the rotating seat are rotatably connected with a first screw, the surface of the first screw is threadedly sleeved with a first screw sleeve, one side of the rotating seat is symmetrically slidably connected with a support rod fixedly connected to the first screw sleeve, a first motor is fixedly installed inside the rotating seat, the output end of the first motor and the end of the first screw close to each other are respectively installed with a first bevel gear and a second bevel gear that mesh with each other, and a reel is sleeved on the surface of the support rod.

[0007] By adopting the above technical solution, the support rods on one side of the rotating seat can be synchronously slid toward or away from each other by turning on the first motor. As a result, the support rods can come into contact with the inner surface of the reel during the sliding process away from each other, and various types of reels can be quickly fixed, which is convenient for winding PETG sheets of different diameters; the lifting seat slides upward to drive the rotating drum to come into contact with the outer surface of the reel. Then, the reel drives the rotating drum to rotate, so that the rotating drum can stick out the solid glue inside the lifting seat during different rotation processes. Then, by contacting with the reel and coating it on the surface of the reel, the rotating drum can evenly apply glue to a large area of the reel surface, reducing the risk of the PETG sheet and the reel being loosened, and improving the winding efficiency.

[0008] The utility model is further configured as follows: a second motor is bolted to one side of the bottom of the support column, a second screw is rotatably connected inside the support column, an output end of the second motor and a bottom of the second screw are fixedly connected to mutually meshing third bevel gears, a second screw sleeve is threadedly sleeved on the surface of the second screw, an end of the second screw sleeve away from the inside of the support column is fixedly connected to a lifting seat, a rotating drum is rotatably connected to the top of the lifting seat, and solid glue used in conjunction with the rotating drum is filled inside the lifting seat.

[0009] By adopting the above technical solution, the rotating drum can evenly apply glue to a large area of the roll surface, reduce the risk of the PETG sheet and the roll being loosened, and improve the winding efficiency.

[0010] The utility model is further configured as follows: clamping plates are slidably sleeved on both sides of the surface of the support rod, and a spring fixedly connected to the clamping plate is fixedly connected inside the support rod.

[0011] By adopting the above technical solution, the clamping plate is driven to slide on the surface of the support rod by the elastic force of the spring, so that after the clamping plate is stretched open by the reel, it can fit with both sides of the reel to clamp and fix the reel on the surface of the support rod.

[0012] The utility model is further configured as follows: a bottom plate is fixedly connected to the bottom of the support column.

[0013] By adopting the above technical solution, the grounding area of the device is increased, and the stability is improved.

[0014] The present utility model is further configured such that: a third motor is bolted to the top of the support column, and the output end of the third motor is fixedly connected to the side of the rotating seat away from the support rod.

[0015] By adopting the above technical solution, by starting the third motor to drive the rotating seat to rotate, the winding drum fixed on the surface of the support rod can wind the PETG sheet.

[0016] The present utility model is further configured such that: a threaded shaft is threadedly connected through the inside of the lifting seat, and the top of the threaded shaft is rotatably connected to a lifting plate.

[0017] By adopting the above technical solution, by rotating the threaded shaft to engage with the lifting seat in a threaded manner, the lifting plate is driven to slide upward, pushing the solid glue inside the lifting seat upward to keep the rotating cylinder in contact with the solid glue.

[0018] The present utility model is further configured such that: a glue injection valve is fixedly communicated with the side of the lifting seat away from the support column.

[0020] The present utility model is further configured such that: sealing gaskets slidably connected to the lifting seat are bonded to both sides of the lifting plate.

[0021] By adopting the above technical solution, the sealing performance is improved, and the leakage of solid glue is avoided.

[0022] In summary, the present utility model has the following beneficial effects:

[0023] 1. By starting the first motor, the support rods on one side of the rotating seat can slide synchronously closer to or away from each other. Thus, during the sliding process of the support rods moving away from each other, they can contact the inner surface of the winding drum, quickly fixing various different models of winding drums, facilitating the winding of PETG sheets with different diameters;

[0024] 2. By the upward sliding of the lifting seat, the rotating cylinder is driven to contact the outer surface of the winding drum. Then, the rotating cylinder is driven to rotate by the winding drum, and the solid glue inside the lifting seat is adhered out during the different rotation processes of the rotating cylinder. Then, by contacting the winding drum, it is coated on the surface of the winding drum, so that the rotating cylinder can uniformly coat a large area of the surface of the winding drum, reducing the risk of the PETG sheet coming loose from the winding drum and improving the winding efficiency.

By turning on the first motor 3, the support rod 8 on one side of the rotating seat 2 can synchronously slide closer to or away from each other. Therefore, the support rod 8 can conflict with the inner surface of the reel 9 during the sliding process away from each other, and a plurality of different types of reels 9 can be quickly fixed, so as to facilitate the winding of PETG sheets of different diameters.

The elastic force of the spring 18 drives the clamping plate 19 to slide on the surface of the support rod 8. Therefore, after the clamping plate 19 is stretched open by the reel 9, it can fit with both sides of the reel 9, and clamp the reel 9 to the surface of the support rod 8.

[0033] refer to Figure 1 , Figure 2, the bottom of the support column 1 is fixedly connected with a bottom plate 22, which increases the grounding area of the device and improves stability.

[0034] Reference Figure 2 , the top of the support column 1 is bolted with a third motor 23, and the output end of the third motor 23 is fixedly connected to the side of the rotating seat 2 away from the support rod 8. By turning on the third motor 23, the rotating seat 2 is driven to rotate, so that the winding drum 9 fixed on the surface of the support rod 8 winds the PETG sheet.

[0035] Brief description of the usage process: By turning on the first motor 3, the first conical gear 5 and the second conical gear 6 mesh with each other to drive the first screw rod 4 inside the rotating seat 2 to rotate synchronously. Then, after the first screw rod 4 is threadedly engaged with the first screw sleeve 7, the support rods 8 on one side of the rotating seat 2 can slide closer to or away from each other synchronously. Thus, during the sliding process of the support rods 8 moving away from each other, they can contact the inner surface of the winding drum 9, so as to quickly fix various different types of winding drums 9. Finally, by turning on the third motor 23, the rotating seat 2 can be driven to rotate, and the winding drum 9 winds the PETG sheet.

[0036] Embodiment 2:

[0037] Reference Figure 1 , Figure 2 , a winding device for PETG sheet production, on one side of the bottom of the support column 1 is bolted with a second motor 10, inside the support column 1 is rotatably connected with a second screw rod 11, the output end of the second motor 10 and the bottom of the second screw rod 11 are both fixedly connected with meshing third conical gears 12, the surface of the second screw rod 11 is threadedly sleeved with a second screw sleeve 13, one end of the second screw sleeve 13 away from the inside of the support column 1 is fixedly connected with a lifting seat 14, the top of the lifting seat 14 is rotatably connected with a rotating cylinder 15, and the inside of the lifting seat 14 is filled with solid glue used in cooperation with the rotating cylinder 15. By the upward sliding of the lifting seat 14, the rotating cylinder 15 is driven to contact the outer surface of the winding drum 9. Then, the winding drum 9 drives the rotating cylinder 15 to rotate, and during different rotation processes of the rotating cylinder 15, the solid glue inside the lifting seat 14 is adhered out. Then, by contacting the winding drum 9, it is coated on the surface of the winding drum 9, so that the rotating cylinder 15 can uniformly coat a large area of the surface of the winding drum 9, reducing the risk of the PETG sheet loosening from the winding drum and improving the winding efficiency.

[0038] Reference Figure 2 , the inside of the lifting seat 14 is threadedly connected through a threaded shaft 16, and the top of the threaded shaft 16 is rotatably connected with a lifting plate 17. By rotating the threaded shaft 16 to be threadedly engaged with the lifting seat 14, the lifting plate 17 is driven to slide upward, pushing the solid glue inside the lifting seat 14 upward to keep the rotating cylinder 15 in contact with the solid glue.

[0039] Reference Figure 2, a glue injection valve 20 is fixedly communicated with the side of the lifting seat 14 away from the support column 1, which is convenient for injecting solid glue into the lifting seat 14 after the solid glue is used up.

[0040] Reference Figure 2 , sealing gaskets 21 that are adhesively connected to both sides of the lifting plate 17 and slidably connected to the lifting seat 14 are provided, which improves the sealing performance and prevents the leakage of solid glue.

After the second screw rod 11 is threadedly engaged with the second nut 13, the lifting seat 14 is driven to slide up and down on one side of the support column 1. Then, the lifting seat 14 slides upward to drive the rotating cylinder 15 to contact the outer surface of the winding drum 9. When driving the winding drum 9 to rotate, since the rotating cylinder 15 contacts the solid glue inside the lifting seat 14, it is relatively sticky, so the frictional force between the surfaces of the winding drum 9 and the rotating cylinder 15 is very large, and thus the rotating cylinder 15 can be driven to rotate, so that the solid glue inside the lifting seat 14 is adhered out during different rotation processes of the rotating cylinder 15. Then, by contacting the winding drum 9, it is coated on the surface of the winding drum 9, and this process is repeated, so that the rotating cylinder 15 can uniformly coat a large area of the surface of the winding drum 9.
