Specific embodiments

[0022] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail through specific embodiments.

[0023] Please refer to Figure 1 , the present utility model provides a polylactic acid film winding device, including a machine table 1, a machine shaft 2, a tensioning roller 3, a power cord 4, a control panel 5 and an auxiliary shearing device 6. The machine shaft 2 is rotatably installed on the upper right side of the machine table 1, and the rotation of the machine shaft 2 is controlled by the machine table 1. The tensioning roller 3 is rotatably installed on the lower right side of the machine table 1. The power cord 4 is connected to the top left side of the machine table 1. The control panel 5 is arranged at the top end of the machine table 1. The auxiliary shearing device 6 is arranged in the middle on the right side of the machine table 1.

[0024] Please refer to Figure 2 , the auxiliary shearing device 6 in the present utility model includes a bracket 61, a tool rest 62, a sliding groove 63, a tool holder 64, a cutting knife 65 and a handle 66. The bracket 61 is installed in the middle on the right side of the machine table 1. The tool rest 62 is hinged and installed on the shaft body in the middle of the bracket 61. The tool rest 62 can be turned forward and backward. A sliding groove 63 is horizontally arranged on the top surface of the tool rest 62. The sliding groove 63 runs longitudinally through the tool rest 62. A tool holder 64 is slidably assembled inside the sliding groove 63. A cutting knife 65 is embedded at the top of the tool holder 64. The cutting knife 65 is used for cutting the film. The handle 66 is installed at the bottom of the tool holder 64 by screws.

[0025] Further explanation: The tool rest 62 is parallel to the machine shaft 2 and the tension roller 3, and the tool rest 62 is located between the machine shaft 2 and the tension roller 3 at a position where the film has been tensioned by the tension roller 3, enabling the cutter 65 to more easily cut the film horizontally and avoiding the situation where the film wrinkles and the cutter 65 cannot cut in smoothly.

[0026] Further explanation: The chute 63 is parallel to the machine shaft 2, and the length of the chute 63 is not less than the length of the machine shaft 2, ensuring that the cutter 65 has sufficient movement range, enabling the cutter 65 to smoothly cut the film and ensuring that the film cut is flat.

[0027] Further explanation: The cutter 65 adopts an arc-shaped blade, and the arc-shaped blade can reduce the resistance when the cutter 65 cuts the film, making the cutting more smooth.

[0028] Please refer to Figures 4 - 5 In the present utility model, a storage box 67 is installed by screws at the top right end of the tool rest 62. The storage box 67 is located directly above the chute 63, and the storage box 67 communicates with the inner side of the chute 63, enabling the cutter 65 to move to the right end of the chute 63 and thus enter the interior of the storage box 67 to provide storage protection for the cutter 65, so that the blade of the cutter 65 will not be exposed, ensuring safety.

[0029] Further explanation: A first magnetic sheet 68 is adhesively laid on the right end face of the chute 63, and a second magnetic sheet 69 is adhesively laid on the right side of the tool holder 64. The second magnetic sheet 69 can generate magnetic adsorption with the first magnetic sheet 68 to position the tool holder 64 at the right end of the chute 63, preventing the cutter 65 from disengaging from the storage box 67 by itself.

[0030] Please refer to Figure 3 In the present utility model, a bracket 610 is integrally provided at the top of the leg of the bracket 61. When the tool rest 62 is turned forward to the horizontal state, the tool rest 62 will be placed on the top of the bracket 610. The bracket 610 can support the tool rest 62 and position the tool rest 62 at the front part of the bracket 61, preventing the tool rest 62 from turning down by itself and blocking the moving path of the film.

[0031] The working principle is as follows:

[0032] First, before the winding operation, the tool rest 62 is first turned forward to the horizontal state, so that the tool rest 62 is placed on the top of the bracket 610, thereby positioning the tool rest 62 at the front part of the bracket 61 and preventing the tool rest 62 from turning down by itself and blocking the moving path of the film.

[0033] Second, when performing the winding operation, first connect the power cord 4 to the external power supply interface to ensure the power supply demand of the machine 1. Then, sleeved the paper tube onto the surface of the machine shaft 2. Subsequently, pass the tail end of the film around the lower part of the tension roller 3 and then wind and fix it onto the surface of the paper tube. Finally, set the number of winding turns through the control panel 5 and start the rotation of the machine shaft 2, so that the machine shaft 2 drives the paper tube to rotate, thereby winding the film onto the surface of the paper tube one by one, thus realizing the winding of the film.

[0034] Third, when the machine shaft 2 reaches the set number of turns, it will automatically stop. At this time, it is necessary to cut and separate the film. The specific operation method is as follows: Flip the tool rest 62 from top to back until the tool rest 62 abuts against the film. Subsequently, the operator holds the handle 66 to control the movement of the tool holder 64, so that the cutter 65 on the tool holder 64 cuts into the film and transversely cuts it. Since the tool holder 64 moves linearly along the sliding groove 63, it is ensured that the cutter 65 can cut the film straight, keeping the film incision flat. Thus, the splitting operation of the film is completed. A cutting function is added to the machine 1. The operator does not need to prepare tools by himself, which is convenient to use and achieves a better cutting effect. After cutting, wind the remaining film onto the paper tube, and then the paper tube can be removed and replaced.

[0035] Fourth, after the cutter 65 is used, the operator holds the handle 66 to control the tool holder 64 to move to the right end of the sliding groove 63, so that the cutter 65 enters the interior of the storage box 67 to provide storage protection for the cutter 65. In this way, the blade of the cutter 65 will not be exposed, ensuring safety. At the same time, the second magnetic piece 69 on the tool holder 64 can generate magnetic adsorption with the first magnetic piece 68 on the sliding groove 63 to position the tool holder 64 at the right end of the sliding groove 63, ensuring that the cutter 65 will not detach from the storage box 67 by itself.

[0036] The utility model provides a polylactic acid film winding device. By arranging an auxiliary shearing device 6 in the middle of the right side of the machine 1, the operator holds the handle 66 to control the movement of the tool holder 64, so that the cutter 65 on the tool holder 64 cuts into the film and transversely cuts it, keeping the film incision flat. Thus, the splitting operation of the film is completed. A cutting function is added to the machine 1. The operator does not need to prepare tools by himself, which is convenient to use and achieves a better cutting effect. By arranging a storage box 67 at the top of the right end of the tool rest 62, after the cutter 65 is used, the operator holds the handle 66 to control the tool holder 64 to move to the right end of the sliding groove 63, so that the cutter 65 enters the interior of the storage box 67 to provide storage protection for the cutter 65. In this way, the blade of the cutter 65 will not be exposed, ensuring safety.

[0037] The above are only the preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
