[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a winding device for fiberglass products, including a fixed frame 1. A rotary clamping member 2 is arranged inside the fixed frame 1. The rotary clamping member 2 includes a driver and a clamping member. After clamping and fixing the mold core 3, it can drive the mold core 3 to rotate, so that the fiberglass can be quickly wound around the outside of the mold core 3. A mold core 3 is arranged inside the rotary clamping member 2. A fiber injector 4 is arranged on the upper side inside the fixed frame 1. A reciprocating lead screw group is arranged outside the fiber injector 4. When the reciprocating lead screw group is started, it can drive the fiber injector 4 to perform a linear reciprocating motion in the left-right direction, so that the fiberglass ejected by the fiber injector 4 can be evenly and reciprocally wound outside the mold core 3, improving the winding effect.

[0033] Referring to Figures 2 - 3 , a collection box 5 is fixedly connected to the inner bottom surface of the fixed frame 1. A scraper 6 is detachably connected inside the collection box 5. When the mold core 3 rotates, the scraper 6 can scrape off the excess glue on the outside of the mold core 3 caused by the winding of the fiberglass, avoiding affecting the forming effect of the fiberglass product. The scraped-off excess glue will slide down along the front surface of the scraper 6. Two inclined platforms 7 are fixedly connected to the left and right sides of the inner bottom surface of the collection box 5 in a mirror image structure. A section of plastic film is laid on the bottom surface of the collection box 5. The inclined platforms 7 will lift the left and right ends of the plastic film upward, so that the plastic film forms a concave structure. The glue sliding down from the scraper 6 will enter the plastic film for collection and treatment. The concave structure can prevent the glue from leaking from the left and right sides of the plastic film.

[0034] A winding unit is arranged on the front surface of the collection box 5. The winding unit includes a mounting frame 71. The mounting frame 71 is fixedly connected to the front surface of the collection box 5. A motor 72 is fixedly connected to the left surface of the mounting frame 71. The right output end of the motor 72 penetrates through the mounting frame 71. The right output end of the motor 72 is fixedly connected to a winding roller 73. When the motor 72 is started, it can drive the winding roller 73 to rotate. The right end of the winding roller 73 is rotatably connected to the inner wall surface of the right side of the mounting frame 71. The staff can wind the plastic film around the outside of the winding roller 73. When the plastic film needs to be used, the motor 72 can be started to drive the winding roller 73 to rotate to release the plastic film, and the operation is simple.

[0035] A pressing plate 8 is provided at the rear side of the scraping plate 6, and an extrusion unit is provided at the rear side of the pressing plate 8. The extrusion unit includes a screw 81. The screw 81 is rotatably connected to the back surface of the pressing plate 8. The rear end of the screw 81 penetrates through the collection box 5. The screw 81 is threadedly connected to the collection box 5. When the screw 81 rotates, it can move linearly in the front-rear direction relative to the collection box 5. At this time, the screw 81 can drive the pressing plate 8 to move synchronously. A handle 82 is fixedly connected to the rear end of the screw 81. A limiting rod 83 is fixedly connected to the back surface of the pressing plate 8. The rear end of the limiting rod 83 penetrates through the collection box 5. The inner wall of the collection box 5 can guide and limit the movement of the limiting rod 83, so that the limiting rod 83 can only move linearly in the front-rear direction, and further can guide and limit the movement of the pressing plate 8, so that the pressing plate 8 can also only move in the front-rear direction.

[0036] After the plastic film enters the interior of the collection box 5, the rear end of the plastic film can be placed in the gap between the scraping plate 6 and the pressing plate 8. Subsequently, the handle 82 can be rotated to drive the screw 81 to rotate. Under the push of the limiting rod 83, the pressing plate 8 is driven to move forward, and cooperates with the scraping plate 6 to squeeze and fix the rear end of the plastic film, so that the plastic film is stably placed at the inner bottom end of the collection box 5. After the fiberglass product is manufactured, after the product is taken away, the front end of the plastic film can be cut off with a sharp object. Subsequently, the handle 82 is turned to drive the pressing plate 8 to move backward, quickly releasing the limit on the rear end of the plastic film. Then, this part of the plastic film with adhesive is taken out and cleaned, so as to prevent the adhesive from accumulating too much in the collection box 5 and affecting the use of the collection box 5 after hardening.

[0037] Refer to Figures 4 - 5 , slots 9 are provided on the inner wall surfaces of the left and right sides of the collection box 5. The left and right ends of the scraping plate 6 are respectively inserted into the slots 9 provided on the left and right side surfaces of the collection box 5. A limiting groove 10 is provided on the surface of the slot 9 away from the scraping plate 6. A clamping block 11 is inserted into the limiting groove 10. The upper end of the surface of the clamping block 11 close to the scraping plate 6 is arranged in an inclined structure. When the end of the scraping plate 6 is inserted into the slot 9, the clamping block 11 can be squeezed along the inclined surface of the clamping block 11, so that the clamping block 11 enters the limiting groove 10. The bottom surface of the clamping block 11 fits with the upper surface of the part of the scraping plate 6 located inside the slot 9. A connecting rod 12 is fixedly connected to the surface of the clamping block 11 away from the scraping plate 6. One end of the connecting rod 12 away from the clamping block 11 penetrates through the collection box 5. A connecting plate 13 is fixedly connected to the end of the connecting rod 12 away from the clamping block 11. The staff can pull the clamping block 11 through the connecting rod 12. A spring 14 is sleeved on the outer side of the connecting rod 12. One end of the spring 14 is fixedly connected to the outer wall of the clamping block 11, and the other end of the spring 14 is fixedly connected to the inner wall surface of the limiting groove 10. When the clamping block 11 moves into the limiting groove 10, the spring 14 can be squeezed, so that the spring 14 compresses to generate elastic potential energy.

[0038] When the scraper 6 is completely inserted into the slot 9, it will contact and squeeze the clamping block 11, causing the clamping block 11 to pop out under the action of the elastic potential energy of the spring 14 to limit and fix the scraper 6. When it is necessary to disassemble and clean the scraper 6, the staff can pull the connecting plate 13 to pull the clamping block 11 into the limiting groove 10 to quickly release the limit on the scraper 6, and the operation is simple and convenient.

[0039] Working principle: Start the motor 72 to release the plastic film, put the rear end of the plastic film into the gap between the pressing plate 8 and the scraper 6, rotate the handle 82 to drive the pressing plate 8 to move forward to squeeze and fix the rear end of the plastic film. After the plastic film is laid at the bottom of the collection box 5, the inclined platform 7 will lift the left and right ends of the plastic film, making the plastic film as a whole arranged in a concave structure. After placing the mold core 3 into the rotary clamping member 2 for clamping and fixing, start the driving member in the rotary clamping member 2 to drive the mold core 3 to rotate. At the same time, the fiber injector 4 automatically sprays and winds fibers onto the mold core 3 until the required thickness is stacked. During the process of rotary winding, the scraper 6 can scrape off the excess glue on the surface of the mold core 3, and the scraped glue will slide down along the inclined surface of the scraper 6 into the plastic film for collection. After taking away the mold core 3 after winding, the staff can cut off the front end of the plastic film, then rotate the handle 82 to release the rear end of the plastic film, and then take away this section of the plastic film for cleaning.
