Description

Technical Field

[0001] This utility model relates to the field of sheet material winding technology, and in particular to a PVC sheet material winding machine. Background Technology

[0002] PVC sheets are made from polyvinyl chloride (PVC) and have properties such as corrosion resistance, insulation, flame retardancy, and waterproofing. Based on their hardness, they can be divided into soft PVC sheets (used for flooring, interior decoration, etc.) and hard PVC sheets (used for building materials, chemical corrosion protection, etc.). They are widely used in architectural decoration, advertising signage, and industrial manufacturing. A PVC sheet winding machine is a specialized piece of equipment used to automatically wind PVC sheets or plates into rolls. It is typically equipped with a constant tension control system, photoelectric correction device, and adjustable speed motor to ensure a smooth, wrinkle-free winding process and improve processing efficiency. It is suitable for winding, packaging, or subsequent processing of cut sheets. These two types of machines correspond to the production and application stages of PVC sheets, respectively.

[0003] Chinese utility model patent application CN201921887760.3 discloses a PVC sheet winding machine, including a base, a main shaft, and a motor. The main shaft is rotatably mounted on the base, and the motor is connected to the main shaft. A lower support is fixedly mounted on the main shaft. One end of the lower support is hinged to an upper support. The other end of the lower support is connected to the upper support via a locking mechanism. The locking mechanism can drive the upper support to swing, with the center of the swing being the hinge point between the upper and lower supports. The upper and lower supports and the locking mechanism allow for convenient disassembly of the roll, and the design is simple and easy to operate.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the winding height and winding guide angle of the above-mentioned devices are fixed, making it difficult to adjust the working state of the devices according to the actual situation and the properties of the sheet material, resulting in a small range of applicability.

[0046] like Figures 1-4 As shown in the figure, this application discloses a PVC sheet winding machine, comprising:

[0047] The positioning bracket 1 has a lifting limit groove inside; the positioning bracket 1 has a fixed connecting rod 101 fixed on both sides inside; and the positioning bracket 1 has vertical limit holes on both sides.

[0048] The lifting operating lever 2 is slidably installed in the lifting limit groove, and its interior is designed with a lifting threaded hole for linkage.

[0049] The linear screw motor 3 is embedded in the bottom of the lifting limit groove, and its output end is threadedly connected to the lifting threaded hole.

[0050] The support positioning plate 4 is fixedly welded to the upper end of the lifting operating rod 2, and a rotating mounting hole is opened at the center position; vertical limiting rods 401 are fixed on both sides of the lower end of the support positioning plate 4, and the vertical limiting rods 401 are slidably arranged inside the vertical limiting hole.

[0051] The winding linkage structure 5 is rotatably mounted within the rotating mounting hole; the winding linkage structure 5 includes:

[0052] The winding operation shaft 501 is rotatably installed in the rotating mounting hole, and has a hexagonal groove inside; the driven gear 502 is fixedly welded to one end of the winding operation shaft 501, and has a telescopic adjustment hole at the center; the winding motor 503 is embedded in the support positioning plate 4 on one side, and its output end is fixedly provided with a drive gear that meshes with the driven gear 502; the linkage support block 504 is slidably installed in the hexagonal groove, and has a telescopic threaded hole at the center; the telescopic screw 505 is rotatably installed in the telescopic adjustment hole and is threadedly connected to the telescopic threaded hole.

[0053] The operating drum 6 is connected to the winding linkage structure 5 and is used to install and wind up PVC rolls. The winding linkage structure 5 is used to rotate the operating drum 6. Both ends of the operating drum 6 are designed with linkage slots that are slidably connected to the linkage support block 504.

[0054] The lever gear 7 is designed on one side of the support positioning plate 4; a storage and installation groove is designed on one side of the support positioning plate 4, and an extension positioning hole is provided at the upper end of the storage and installation groove; a rotating connecting shaft is integrally designed on the outer side of the lever gear 7 and is rotatably installed in the extension positioning hole.

[0060] When it is necessary to adjust the angle of the guide roller 10 to better support and guide the PVC sheet, the angle adjustment motor 8 is started. The power gear at the output end of the angle adjustment motor 8 drives the lever gear 7 to rotate. The lever gear 7 drives the extension support rod 9, which is fixedly welded to it, to rotate, thereby adjusting the angle of the guide roller 10 so that the guide roller 10 can accurately support and guide the PVC sheet.

All technical solutions falling within the scope of this utility model's concept are within its protection scope.
