[0021] Please refer to Figures 1 to 4 , an on-line recycling system for plastic film production edge materials, including a fixed seat 1. An electric guide rail 101 is installed on the lower end surface of the inner wall of the fixed seat 1. The outer wall of the electric guide rail 101 is slidably connected with a limit ring 102 through an electric sliding sleeve. The right side of the inner wall of the fixed seat 1 is movably connected with a first fixed disk 2. A fixed shaft 201 is fixedly connected to the left side of the first fixed disk 2. A fixed ring 3 is sleeved on the outer wall of the fixed shaft 201. A take-up reel 302 located on the outer wall of the fixed shaft 201 is fixedly connected to the left side of the fixed ring 3.

[0022] A plurality of sliding grooves 303 are formed on the outer wall of the take-up reel 302. A moving disk 4 is movably connected to the outer wall of the take-up reel 302. A plurality of cutting knives 401 located inside the sliding grooves 303 are installed on the left side of the moving disk 4. A spring 402 is installed between the other side of the moving disk 4 and the fixed ring 3.

[0023] In this embodiment: The take-up reel 302 is sleeved on the outer wall of the fixed shaft 201. At the same time, the right side of the fixed ring 3 abuts against the first fixed disk 2. Then, the second fixed disk 5 is placed on the left side of the fixed shaft 201, and the second fixed disk 5 is rotated to drive the limit cap 501 to rotate and be threadedly connected to the inner wall of the fixed shaft 201 and the outer wall of the take-up reel 302. Then, the recycled plastic film is placed in the limit ring 102, and the electric guide rail 101 is driven to move the limit ring 102 left and right. At the same time, the first fixed disk 2 is driven to rotate by a motor on the right side of the fixed seat 1, so as to drive the fixed shaft 201 and the take-up reel 302 to rotate, and then the recycled plastic film can be wound around the outer wall of the take-up reel 302.

[0024] After the plastic film recycling is completed, the second fixed disk 5 can be rotated to drive the limit cap 501 to rotate, so that the limit cap 501 is separated from the fixed shaft 201 and the winding drum 302. Then, the fixed ring 3 is pushed to the left, so that the winding drum 302 moves to the left on the outer wall of the fixed shaft 201 until the winding drum 302 is separated from the fixed shaft 201, thus facilitating the replacement of the winding drum 302 for recycling plastic film. Then, hold and push the moving disk 4 to the left, so that the moving disk 4 drives the cutting knife 401 to move leftward in the sliding groove 303. The plastic film wound around the outer wall of the winding drum 302 can be cut by a plurality of cutting knives 401, thus realizing the cutting and removal of the recycled and wound plastic film and centralized collection, thereby improving the efficiency of plastic film recycling.

[0025] As a technical optimization scheme of the present utility model, an installation long groove 203 is provided on the outer wall of the fixed shaft 201, and an installation boss 304 matched with the installation long groove 203 is fixedly connected to the inner wall of the winding drum 302.

[0026] In this embodiment: The winding drum 302 is slidably sleeved on the outer wall of the fixed shaft 201, and the installation long groove 203 corresponds to the installation boss 304, so as to complete the positioning installation of the winding drum 302 and the fixed shaft 201, so that the winding drum 302 can be driven to rotate while the first fixed disk 2 drives the fixed shaft 201 to rotate.

[0027] As a technical optimization scheme of the present utility model, a positioning groove 202 is provided on the left side of the first fixed disk 2, and a positioning block 301 matched with the positioning groove 202 is fixedly connected to the right side of the fixed ring 3.

[0029] As a technical optimization scheme of the present utility model, a circular hole is provided through the middle of the outer wall of the moving disk 4.

[0030] In this embodiment: The moving disk 4 can move smoothly on the outer wall of the winding drum 302 through the circular hole.

[0031] As a technical optimization scheme of the present utility model, the lower end surface of the second fixed disk 5 contacts the left side of the bottom end of the inner wall of the fixed seat 1.

[0032] In this embodiment: Through the contact between the lower end surface of the second fixed disk 5 and the left side of the bottom end of the inner wall of the fixed seat 1, while the fixed seat 1 supports the second fixed disk 5, it can also separate the second fixed disk 5 from the fixed seat 1.

[0033] Working principle:

[0034] First, the winding drum 302 is sleeved on the outer wall of the fixed shaft 201 through the cooperation of the installation slot 203 and the installation boss 304. At the same time, the right side of the fixing ring 3 abuts against the first fixing plate 2, and the positioning block 301 is located in the positioning slot 202. Then, the second fixing plate 5 is placed on the left side of the fixed shaft 201, and the second fixing plate 5 is rotated to drive the limit cap 501 to rotate and be threadedly connected to the inner wall of the fixed shaft 201 and the outer wall of the winding drum 302. Next, the recycled plastic film is placed in the limit ring 102, and the limit ring 102 is driven to move left and right by the electric guide rail 101. At the same time, the first fixing plate 2 is driven to rotate by the motor on the right side of the fixed seat 1, so as to drive the fixed shaft 201 and the winding drum 302 to rotate, and then the recycled plastic film can be wound around the outer wall of the winding drum 302.

[0035] When the recycling of the plastic film is completed, the second fixing plate 5 can be rotated to drive the limit cap 501 to rotate, so that the limit cap 501 is separated from the fixed shaft 201 and the winding drum 302. Then, the fixing ring 3 is pushed to the left to make the winding drum 302 move left on the outer wall of the fixed shaft 201 until the winding drum 302 is separated from the fixed shaft 201, thus facilitating the replacement of the winding drum 302 for recycling the plastic film. Immediately afterwards, the fixing pin for fixing the moving plate 4 and the fixing ring 3 is removed, and then the moving plate 4 is held and pushed to the left to drive the cutting knife 401 to move left in the sliding slot 303, and the spring 402 is stretched. Then, the plastic film wound around the outer wall of the winding drum 302 can be cut off by the plurality of cutting knives 401 and collected centrally.

[0036] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "left", "right", "up", "down", "top", "bottom", "front", "rear", "inner", "outer", "back", "middle", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0037] However, the above are only specific embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. Therefore, the replacement of equivalent components or the equivalent changes and modifications made according to the scope of patent protection of the present invention should still fall within the scope covered by the claims of the present invention.
