Description

Technical Field

[0001] This utility model relates to the technical field of polyester film production equipment, and more specifically, to a winding device for 6-micron polyester film. Background Technology

[0002] In polyester film production, the formed polyester film needs to be wound up and packaged by a winding device for easy storage and transportation. Polyester film winding devices typically utilize conveyor rollers for transport. However, current conveyor rollers are prone to defects such as film deviation, wrinkles, streaks, and creases due to precision issues or film tension problems during transport. This can even prevent the polyester film from completing the designated process stably or being wound neatly. Furthermore, dust particles easily adhere to the polyester film during winding, causing contamination. Utility Model Content

The specific implementation of this utility model is described in more detail below with reference to specific embodiments:

[0029] like Figure 1 , Figure 2 and Figure 3As shown, this utility model embodiment provides a winding device for 6-micron polyester film, used along the production direction (e.g., Figure 1 The polyester film 10 is wound up (in the direction indicated by the middle arrow), including a frame 1, a winding roller 2, a dust removal assembly 3, a tension adjustment assembly 4, and a conveyor roller 5; the winding roller 2 is rotatably connected to the frame 1; the dust removal assembly 3 is rotatably connected to the frame 1 and is located in front of the winding roller 2 along the production direction, for adsorbing dust particles on the polyester film 10; the tension adjustment assembly 4 is connected to the frame 1 and is located in front of the dust removal assembly 3 along the production direction, for adjusting the tension of the polyester film 10; the conveyor roller 5 is rotatably connected to the frame 1 and is located in front of the tension adjustment assembly 4 along the production direction, for conveying the polyester film 10.

[0030] Specifically, the polyester film 10 is conveyed along the production direction by the conveying roller 5. The tension adjusting component 4 presses the polyester film 10 downward to increase its tension, thus preventing the polyester film from deviating and avoiding defects such as wrinkles, streaks, and creases. Then, it passes through the dust removal component 3, which removes dust particles from the surface of the polyester film 10. Finally, the take-up roller 2 winds up and stores the polyester film 10.

[0031] In one optional embodiment of this invention, the take-up roller 2 includes a take-up roller body 21, a take-up motor 22, a rotating shaft 23, and baffles 24. Baffles 24 are provided at both ends of the take-up roller body 21. The rotating shaft 23 is connected to the take-up roller body 21 and passes through the baffles 24 to connect to the output shaft of the take-up motor 22. The baffles 24 at both ends of the take-up roller body 21 are used to limit the polyester film 10, preventing the polyester film 10 from shifting along the axial direction of the take-up roller body 21 during the take-up process.

[0032] Preferably, the take-up roller 22 further includes fasteners that securely connect the baffle 24 and the take-up roller body 21. Connecting the baffle 24 and the take-up roller body 21 with fasteners facilitates the disassembly and installation of the baffle. Fasteners include, but are not limited to, bolts and screws.

[0033] In one optional embodiment of this invention, the dust removal assembly 3 includes a first dust removal roller 31, a second dust removal roller 32, a first dust collection paper roll 33, and a second dust collection paper roll 34. The first dust removal roller 31 and the second dust removal roller 32 are disposed opposite to each other and attached to both sides of the polyester film 10. The dust collection paper on the first dust collection paper roll 33 is connected to the first dust removal roller 31, and the dust collection paper on the second dust collection paper roll 34 is connected to the second dust removal roller 32. The first dust collection paper roll 33 is used to transfer dust from the first dust removal roller 31, and the second dust collection paper roll 34 is used to transfer dust from the second dust removal roller 32.

[0034] In one optional embodiment of this invention, the tension adjustment assembly 4 includes a drive motor 41, a lead screw 42, a connecting base 43, and a pressure roller 44. The drive motor 41 is fixedly connected to the frame 1, the lead screw 42 is connected to the output end of the drive motor 41, the connecting base 43 is threadedly connected to the lead screw 42, and the pressure roller 44 is rotatably connected to the connecting base 43. The drive motor 41 drives the lead screw 42 to rotate, thereby causing the connecting base 43 to move along the length direction of the lead screw 42, and finally driving the pressure roller 44 to move in a direction perpendicular to the surface of the polyester film 10, thereby pressing or releasing the polyester film 10. When the pressure applied by the pressure roller 44 to the polyester film 10 increases, the tension of the polyester film 10 also increases accordingly, thereby achieving the adjustment of the tension of the polyester film 10. Specifically, the number of drive motor 41, lead screw 42 and connecting base 43 is preferably two. One end of pressure roller 44 is connected to one connecting base 43 and the other end of pressure roller 44 is connected to another connecting base 43. Through symmetrical driving on both sides, pressure roller 44 can apply pressure to polyester film 10 stably and uniformly.

[0035] In one optional embodiment of this invention, the tension adjusting assembly 4 further includes two guide rods 45. A guide hole is provided on the connecting base 43, and the guide rods 45 pass through the guide hole. The length direction of the guide rods 45 is parallel to the length direction of the lead screw 42. The guide rods 45 serve a guiding function, restricting the connecting base 43 to move only along the length direction of the lead screw.

[0036] In one optional embodiment of this invention, the pressure roller 44 is a rubber roller. The surface of the rubber roller is relatively soft and will not damage the polyester film 10 when it is squeezed.

[0037] As one optional implementation of this embodiment, the frame 1 is made of stainless steel. Stainless steel is durable and can effectively extend the service life of the equipment.

[0038] Specifically, the 6-micron polyester film winding device provided in this embodiment can be used in a 10400mm wide polyester film production line. The manufacturing process of the 10400mm wide polyester film production line is as follows: polyester melt – extruder – metering pump – filter – melt conveying pipeline – static mixer – adapter – die – casting – longitudinal stretching – transverse stretching – thickness measurement – ​​edge trimming – traction – winding – material inspection – slitting – quality inspection – packaging – winding and warehousing. This 6-micron polyester film winding device can be used in the first winding process.

[0039] Preferably, the 10400mm wide polyester film is developed and produced using melt direct stretching technology, which has the advantages of higher quality, lower cost, and larger scale compared with the commonly used slice indirect stretching process at home and abroad; the polyester film is preferably produced by five-layer co-extrusion of ABRBA to reduce production costs and improve product performance; recycled materials and trimmed materials are used to reduce costs.

[0040] The following technical means are used to control production quality during the production process:

[0041] 1. Change the filter design type, reduce foreign matter inside the membrane, and improve product quality.

[0042] 2. Optimize process parameters to improve the stability of the inner membrane of the bellows.

[0043] 3. The online trimmed material can be directly returned to the R-layer extruder, eliminating the need for secondary granulation and saving energy.

[0044] 4. Control the longitudinal heat shrinkage rate of the 6μm polyester film to be less than 2.0% and the transverse heat shrinkage rate to be less than 0.5%.

[0045] 5. Control the thickness flatness of the 6μm polyester film to ensure that the average thickness deviation 2-sigma value is less than 2%.

[0046] 6. Control the longitudinal tensile strength of the 6μm polyester film to be greater than 220 MPa and the transverse tensile strength to be greater than 210 MPa.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
