Description

Technical Field

[0001] This utility model relates to the field of masking film processing technology, specifically to a winding device for masking film. Background Technology

[0002] Masking film is mainly used in various painting, decoration and protection scenarios. It can effectively prevent paint leakage. In the processing of masking film, winding is an important step. By winding, the masking film can be rolled into a compact roll, which is convenient for storage and transportation and reduces space occupation. Therefore, a winding device is required.

[0003] However, during the winding process of the shielding film, friction between the film and the core, as well as between the film layers, generates heat. During continuous operation, the core temperature can reach 45-50℃. Due to the differences in the coefficients of thermal expansion of different materials, the degree of expansion of the film varies with temperature. After winding is completed, the film begins to cool and shrink as the temperature gradually decreases. However, because the coefficients of expansion and the degree of shrinkage of each film layer are not entirely consistent, shrinkage stress is generated. This uneven distribution of stress ultimately causes the rolled shielding film to exhibit a deformation phenomenon similar to a "telescope" after cooling; that is, the film at the core becomes loose, while the outer film may wrinkle or deform due to excessive shrinkage. Utility Model Content

[0004] The purpose of this invention is to provide a winding device for masking film, which has the effect of cooling the core by circulating coolant during the winding process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a winding device for shielding film, comprising a base, supports, and hollow columns, wherein the number of supports is two sets, and further comprising:

[0006] A hollow column is rotatably connected to the surface of the support. A cylinder is bolted to one side inside the hollow column. Short pipes and connecting pipes are respectively connected to both sides of the cylinder. A transverse cylinder is also bolted to the inside of the hollow column, and the other end of the short pipe is connected to the transverse cylinder.

[0007] A rotating column is rotatably connected inside the transverse cylinder. The surface of the rotating column is bolted with helical blades. A return pipe is also connected to the other side of the bottom of the transverse cylinder. An annular pipe is provided on the surface of the hollow column. The other end of the connecting pipe is connected to the annular pipe. The other end of the return pipe is connected to the annular pipe. Several heat-conducting plates are also welded to the surface of the annular pipe.

[0008] A transmission assembly for driving the rotating column to rotate.

[0009] Preferably, the transmission assembly includes a ring gear, a first rotating rod, and a second rotating rod. The ring gear is bolted to the surface of the support. The first rotating rod and the second rotating rod are both fixed to the inner wall of the hollow column by bearings. A first gear and a second gear are bolted to the surfaces of the first rotating rod and the second rotating rod, respectively. The first gear and the second gear mesh with each other. A third gear that meshes with the second gear is also bolted to the surface of the rotating column.

[0010] Preferably, the first gear has the same size as the second gear, and the bottom of the hollow column is provided with a groove for the first gear and the second gear to pass through.

[0011] Preferably, a vertical plate is bolted to one side of the top of the base, a hydraulic rod is provided through the surface of the vertical plate, and the output shaft of the hydraulic rod is bolted to the surface of one set of supports.

[0023] Please see Figures 1-5 As shown, a winding device for shielding film includes a base 1, supports 2, and hollow columns 3. There are two sets of supports 2. A vertical plate 4 is bolted to one side of the top of the base 1. A hydraulic rod 5 is threaded through the surface of the vertical plate 4, and the output shaft of the hydraulic rod 5 is bolted to the surface of one set of supports 2. A slide rail 6 is also bolted to the top of the base 1, and one set of supports 2 is slidably connected to the surface of the slide rail 6, allowing the supports 2 on that side to move more stably. The other set of supports 2 is bolted to the top of the base 1. The device also includes a transmission assembly 17. A hollow column 3 is rotatably connected to the surface of the supports 2. A cylinder 7 is bolted to one side of the interior of the hollow column 3. Short pipes 11 and connecting pipes 13 are respectively connected to both sides of the cylinder 7. The interior of the hollow column 3... A transverse cylinder 8 is also bolted to it, and the other end of the short pipe 11 is connected to the transverse cylinder 8. A rotating column 9 is rotatably connected inside the transverse cylinder 8, and a spiral blade 10 is bolted to the surface of the rotating column 9. A return pipe 12 is also connected to the other side of the bottom of the transverse cylinder 8. An annular pipe 14 is provided on the surface of the hollow column 3. The other end of the connecting pipe 13 is connected to the annular pipe 14, and the other end of the return pipe 12 is connected to the annular pipe 14. Several heat-conducting plates 15 are also welded to the surface of the annular pipe 14, and both the annular pipe 14 and the heat-conducting plates 15 are made of metal. A fixing rod 16 is also bolted to the surface of the hollow column 3, and a fixing sleeve 18 is bolted to the other end of the fixing rod 16 and fitted onto the surface of the annular pipe 14 to achieve auxiliary fixation of the annular pipe 14 and increase the stability of the annular pipe 14.

[0024] The transmission assembly 17 includes a ring gear 171, a first rotating rod 172, and a second rotating rod 173. The ring gear 171 is bolted to the surface of the support 2. The first rotating rod 172 and the second rotating rod 173 are both fixed to the inner wall of the hollow column 3 by bearings, which enables the first rotating rod 172 and the second rotating rod 173 to rotate. The surfaces of the first rotating rod 172 and the second rotating rod 173 are respectively bolted with a first gear 174 and a second gear 175. The first gear 174 and the second gear 175 mesh with each other. The surface of the rotating column 9 is also bolted with a third gear 176 that meshes with the second gear 175. The size of the first gear 174 is the same as the size of the second gear 175. The bottom of the hollow column 3 is also provided with a groove for the first gear 174 and the second gear 175 to pass through.

[0025] Before operation, the cylinder 7, transverse cylinder 8, short pipe 11, connecting pipe 13, return pipe 12, and annular pipe 14 are all filled with heat transfer oil. During operation, the required membrane roll is first aligned with one set of hollow columns 3. Then, the hydraulic rod 5 is activated to extend its output shaft, moving one set of supports 2. The hollow column 3 on that side then enters the other end of the membrane roll. A motor for driving is also installed on the support 2, transmitting power through gears. Activating the motor rotates the hollow column 3, which in turn rotates the roll for winding. The hollow column 3 drives the first rotating rod 172, the second rotating rod 173, the first gear 174, and the second gear 175 in a circular motion. The first gear 174 moves in a circular motion along the inner wall of the ring gear 171, causing the first gear 174 and the first rotating rod 172 to rotate, which in turn drives the second rotating rod 173 and the second gear... The cylinder rotates at 175 degrees, driving the third gear 176 and the rotating column 9 to rotate, causing the spiral blades 10 to rotate. This drives the hydraulic oil inside the transverse cylinder 8 to flow, simultaneously propelling the heat transfer oil inside the short pipe 11, cylinder 7, connecting pipe 13, annular pipe 14, and return pipe 12 to flow together, achieving the circulation of the heat transfer oil. During the winding process, the core temperature can reach 45-50℃, which transfers heat to the inside of the hollow column 3 and to the heat transfer oil inside the cylinder 7, causing the temperature inside the core to drop. When the flowing heat transfer oil passes through the annular pipe 14, it transfers heat to the surface of the heat transfer sheet 15. As the heat transfer sheet 15 and the annular pipe 14 follow the rotation of the hollow column 3 and make circular motions, they disturb the surrounding air, causing air flow and cooling the heat transfer sheet 15, thereby lowering the temperature of the heat transfer oil flowing inside the annular pipe 14 and maintaining the cooling effect on the core.
