[0030] In order to facilitate the recovery work of the recovery assembly 7, as an embodiment of the present application, the recovery assembly 7 comprises two groups of side frames 8, the winding machine 2 is connected with the side frames 8 through a truss 9, the lower ends of the side frames 8 are provided with supporting wheels 10, the two groups of side frames 8 are connected through a connecting plate 11, an arc-shaped frame 12 with an opening upward is connected between the two groups of side frames 8, the upper ends of the side frames 8 are connected with first air cylinders 13, the movable ends of the first air cylinders 13 are connected with supports 14, and the supports 14 are rotatably connected with first auxiliary rollers 15 in rolling contact with the inner lining plate 6.

[0031] In use, one of the two groups of side frames 8 is connected with the bottom of the winding machine 2 through the truss 9 and moves synchronously with the winding machine 2; the supporting wheels 10 at the lower ends of the side frames 8 support on the ground to ensure that the recovery assembly 7 moves stably; and the arc-shaped frame 12 is opposite to the winding position below the square core mold 1 to receive the falling materials.

[0032] It should be noted that, in use, the arc-shaped frame 12 is opposite to the winding position of the square core mold 1 of the winding forming machine, and the first auxiliary roller 15 is located in front of the winding position, that is, the first auxiliary roller 15 does not contact the square core mold 1 after winding the materials, so as to avoid that the glue of the winding materials adheres to the first auxiliary roller 15.

[0033] In order to facilitate the collection of the materials falling into the arc-shaped frame 12, as an embodiment of the present application, the two ends of the arc-shaped frame 12 are connected with the upper parts of the side frames 8 through the fixed ends of arc-shaped cylinders 16, the arc-shaped cylinders 16 are communicated with the first air cylinders 13 through pipelines, and the movable ends of the arc-shaped cylinders 16 are connected with scraping plates 17 in sliding contact with the inner walls of the arc-shaped frame 12.

[0034] In use, when the first cylinder 13 extends and retracts, the air pressure is transmitted to the arc-shaped cylinder 16 through the pipeline to drive the movable end of the arc-shaped cylinder 16 to move synchronously, and the scraper 17 at the lower end of the movable end of the arc-shaped cylinder 16 is in sliding contact with the inner wall of the arc-shaped frame 12, thereby completing the cleaning of the arc-shaped frame 12 and the collection of the falling materials; when the square core mold 1 rotates, the square core mold 1 presses the first auxiliary roller 15, thereby repeatedly pressing the first cylinder 13, so that the scraper 17 moves with the arc-shaped cylinder 16 to slide back and forth along the inner wall of the arc-shaped frame 12, and the residual resin or fiber waste in the arc-shaped frame 12 is scraped, facilitating the subsequent recycling work and preventing accumulation and keeping the equipment clean.

[0035] In order to avoid the influence of the upward scraping of the scraper 17 on the recycling convenience, as an embodiment of the present application, the movable end of the arc-shaped cylinder 16 is fixedly connected with a horizontal support shaft 18, the support shaft 18 is rotatably connected with the upper part of the scraper 17 through a damping bearing, and the lower end surface of the scraper 17 is an arc-shaped surface that is in close contact with the inner wall of the arc-shaped frame 12.

[0036] In use, the arc-shaped surface of the lower end surface of the scraper 17 can ensure that the lower end of the scraper 17 can be in close contact with the inner wall of the arc-shaped frame 12 when the scraper 17 scrapes downward, thereby ensuring the cleaning effect and avoiding excessive swinging of the scraper 17 away from the inner wall of the arc-shaped frame 12; on the contrary, when the scraper 17 scrapes upward, the scraper 17 is facilitated to swing toward the axis of the arc-shaped frame 12, so that the scraper 17 is separated from the inner wall of the arc-shaped frame 12, and the upward scraping of the scraper 17 with the waste is effectively reduced.

[0037] In order to facilitate the discharging work of the arc-shaped frame 12, as an embodiment of the present application, the middle part of the arc-shaped frame 12 is concave to form an arc-shaped discharge chute 20, a spiral discharge shaft 21 is arranged in the discharge chute 20, a discharge port 22 corresponding to the spiral discharge shaft 21 is arranged on the side surface of the discharge chute 20, and the end of the spiral discharge shaft 21 away from the discharge port 22 is rotatably connected with the inner wall of the discharge chute 20.

[0038] In use, after the waste is scraped into the discharge chute 20 by the scraper 17, the waste is pushed from the discharge port 22 to a collection container by rotating the spiral discharge shaft 21, thereby realizing automatic conveying of the waste and avoiding manual cleaning.

[0039] In order to further facilitate the control of the state of the scraper 17, as an embodiment of the present application, the inner side of each end of the arc-shaped frame 12 is connected with a first stop rod that is magnetically adsorbed with the scraper 17, the inner side of the lower part of the arc-shaped frame 12 is connected with two groups of second stop rods that are magnetically adsorbed with the scraper 17, and the two groups of second stop rods are arranged on the two sides of the discharge chute 20.

[0041] When the scraper 17 is lowered and magnetically adsorbed to the second stop rod, the second stop rod pulls the lower end of the scraper 17 to swing to one side of the second stop rod, so that the lower end of the scraper 17 is separated from the inner wall of the arc-shaped frame 12, thereby avoiding the upward scraping of the waste by the scraper 17 during the upward resetting, and affecting the subsequent recycling effect.

[0043] In use, as the square core mold 1 rotates, the square core mold 1 repeatedly extrudes the second cylinder 27 to compress the gas, thereby repeatedly driving the third cylinder 32 to repeatedly stretch; when the third cylinder 32 stretches, the movable ring 28 moves away from the third cylinder 32, at this time, the one-way bearing 30 is locked, and the spiral discharge shaft 21 is driven to rotate by the cooperation of the positioning protrusion 29 and the spiral guide groove 26, so as to discharge the waste in the discharge slot 20; when the extrusion force on the second cylinder 27 decreases, the second cylinder 27 automatically resets and stretches, at this time, the third cylinder 32 automatically resets and shortens, the one-way bearing 30 is in an unlocked state, and the movable ring 28 can quickly slide in the cavity 25.

[0044] It should be noted that the second auxiliary roller 34 does not contact the square core mold 1 after winding the material, so as to avoid the adhesive of the winding material from adhering to the first auxiliary roller 15.
