Description

Technical Field

[0001] This utility model relates to the field of plastic film coating and winding technology, specifically an automated PVC recycled plastic film coating and winding machine. Background Technology

[0002] PVC recycled plastic film is a material produced by processing recycled PVC plastic for film coating processes. It can be used in fields such as agriculture and construction engineering, reducing plastic waste and negative environmental impact. After molding, PVC recycled plastic film needs to be rolled up by a reel for easy transportation, sales and storage.

[0003] Currently, when winding PVC recycled plastic film, once the predetermined amount of plastic film wound on a winding drum is reached, the winding drum needs to be disassembled and replaced with a new one before the plastic film can continue to be wound. This replacement of the winding drum takes a long time, resulting in a large amount of plastic film being wasted due to unwound film. To address this, we propose an automated PVC recycled plastic film winding machine. Utility Model Content

[0004] The purpose of this utility model is to provide an automated PVC recycled plastic film coating and winding machine, which has the advantages of saving the time of changing the winding drum during the PVC recycled plastic film winding process, avoiding the waste of a large amount of plastic film due to unwound film, and improving work efficiency. It solves the problem that when the plastic film wound on a winding drum reaches the predetermined amount, the winding drum needs to be disassembled and replaced with a new winding drum in order to continue winding the plastic film. The time required for changing the winding drum is long, resulting in a large amount of plastic film wasted due to unwound film.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated PVC recycled plastic film coating and winding machine, comprising a vertical plate and winding rollers. A rotating plate is rotatably mounted on the front surface of the vertical plate via a rotating shaft. Winding rollers are rotatably mounted on both ends of the front surface of the rotating plate. A transmission gear is fixedly connected to one end of each winding roller near the rear surface of the rotating plate. A winding motor is fixedly mounted on the rear surface of the vertical plate. A motor gear is fixedly connected to the end of the output shaft of the winding motor, and the motor gear and the transmission gear mesh. A through hole is provided at the middle position of the front surface of the rotating plate, and a sliding rod is slidably inserted into the through hole. Insertion holes are symmetrically provided on both sides of the rotating shaft on the front surface of the vertical plate.

[0006] Preferably, a helical spring is spirally wound on the outer surface of the slide rod, and the two ends of the helical spring are respectively fixedly connected to the outer surface of the slide rod and the front surface of the rotating plate. The elastic force of the helical spring is used to insert one end of the slide rod into the insertion hole, preventing the slide rod from slipping out of the insertion hole.

[0007] Preferably, guide rollers are rotatably installed on the front surface of the rotating plate near the two take-up rollers, and the guide rollers guide the PVC recycled plastic film being wound onto the outer surface of the take-up drum.

[0008] Preferably, limit rings are fixedly installed on the outer surfaces of both guide rollers near both ends. The limit rings limit the PVC plastic film before winding, which helps the plastic film to be neatly wound onto the outer surface of the winding drum and prevents deviation.

[0009] Preferably, a fixing ring is fixedly installed on the outer surface of each of the two take-up rollers near the rotating plate, and a screw is fixedly connected to the end of each of the two take-up rollers away from the fixing ring. Nuts are movably sleeved on the outer surface of each of the two screws, and pressure rings are fixedly installed on the rear surface of each of the two nuts. When the take-up drum is sleeved on the outer surface of the take-up roller, the nuts are turned so that the fixing ring and pressure ring fix and press the two ends of the take-up drum tightly, thereby fixing the take-up drum on the take-up roller.

[0010] Preferably, a base is fixedly installed on the lower surface of the vertical plate, and fixing holes are provided on the upper surface of the base near the four corners. After the bolts pass through the fixing holes, the base is fixed in the position of use.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a vertical plate, a rotating shaft, a rotating plate, a winding roller, a transmission gear, a winding motor, a motor gear, a through hole, a slide rod, and an insertion hole, achieves the effect of saving the time of changing the winding drum during the winding process of PVC recycled plastic film, avoiding the waste of a large amount of plastic film due to not being wound up, and improving work efficiency. The winding motor drives the upper winding roller and the winding drum on its surface to rotate through the motor gear and the transmission gear, so that the PVC recycled plastic film is wound onto the outer surface of the winding drum. At this time, a new winding drum can be fixedly fitted onto the lower winding drum. On the outer surface of the roller, when the amount of plastic film wound on the upper take-up drum reaches the predetermined amount, the connection between the plastic film and the upper take-up drum is cut off, the slide bar is pulled to separate it from the insertion hole, and then the rotating plate is rotated to exchange the positions of the upper and lower take-up rollers. The slide bar is then inserted into the insertion hole to fix the rotating plate, and the new take-up drum rotates to the top to continue winding the plastic film. The take-up drum on the lower take-up roller is then removed and replaced with a new take-up drum. This operation process greatly saves the time wasted during the take-up drum replacement process and avoids the waste of a large amount of plastic film due to not being wound.

[0013] 2. By setting a helical spring, this utility model utilizes the elastic force of the helical spring to insert one end of the slide rod into the insertion hole, preventing the slide rod from slipping out of the insertion hole.

[0014] 3. By setting guide rollers and limiting rings, this utility model guides and limits the PVC recycled plastic film wound on the outer surface of the winding drum, which helps the plastic film to be wound in an orderly manner on the outer surface of the winding drum and prevents the plastic film from deviating during the winding process.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-4As shown, this utility model proposes an automated PVC recycled plastic film coating and winding machine, including a vertical plate 2 and winding rollers 9. A base 7 is fixedly installed on the lower surface of the vertical plate 2. Fixing holes 8 are provided on the upper surface of the base 7 near the four corners. Bolts pass through the fixing holes 8 to fix the base 7 in the use position. A rotating plate 1 is rotatably installed on the front surface of the vertical plate 2 via a rotating shaft 5. Winding rollers 9 are rotatably installed on the front surface of the rotating plate 1 near both ends. The winding rollers 9 and the rotating plate 1 are rotatably connected by bearings. The winding rollers 9 pass through the rotating plate 1. A retaining ring 16 is fixedly installed on the outer surface of the two take-up rollers 9 near the rotating plate 1. A screw 19 is fixedly connected to the end of each take-up roller 9 away from the retaining ring 16. Nuts 18 are movably sleeved on the outer surface of each screw 19. Pressure rings 17 are fixedly installed on the rear surface of each nut 18. When the take-up drum is sleeved on the outer surface of the take-up roller 9, the nuts 18 are turned so that the retaining ring 16 and pressure rings 17 fix and press the two ends of the take-up drum to fix the take-up drum on the take-up roller 9. The formed PVC recycled plastic film is wound on the outer surface of the take-up drum for easy transportation and sale.

[0023] Two take-up rollers 9 are fixedly connected to one end of the rear surface of the rotating plate 1 with transmission gears 15. A take-up motor 3 is fixedly installed on the rear surface of the vertical plate 2. A motor gear 4 is fixedly connected to the end of the output shaft of the take-up motor 3, and the motor gear 4 and the transmission gear 15 mesh. The take-up motor 3 drives the take-up rollers 9 to rotate through the motor gear 4 and the transmission gear 15, so that the PVC recycled plastic film is wound on the outer surface of the take-up drum. A through hole 12 is provided in the middle of the front surface of the rotating plate 1. A slide rod 14 is slidably inserted into the through hole 12. A spiral spring 13 is spirally wound on the outer surface of the slide rod 14, and the two ends of the spiral spring 13 are fixedly connected to the outer surface of the slide rod 14 and the front surface of the rotating plate 1, respectively. Insertion holes 6 are symmetrically provided on both sides of the rotating shaft 5 on the front surface of the vertical plate 2. After one end of the slide rod 14 is inserted into the insertion hole 6, the rotating plate 1 can be fixed. The elastic force of the spiral spring 13 acts on the slide rod 14 to prevent the slide rod 14 from slipping out of the insertion hole 6.

[0024] In use, the winding motor 3 drives the upper winding roller 9 and its surface winding drum to rotate via the motor gear 4 and transmission gear 15, so that the PVC recycled plastic film is wound onto the outer surface of the winding drum. At this time, a new winding drum can be fixedly fitted onto the outer surface of the lower winding roller 9. When the amount of plastic film wound on the upper winding drum reaches the predetermined amount, the connection between the plastic film and the upper winding drum is cut off, the slide rod 14 is pulled to separate it from the insertion hole 6, and then the rotating plate 1 is rotated to interchange the positions of the upper and lower winding rollers 9. The slide rod 14 is then inserted into the insertion hole 6 to fix the rotating plate 1, and the new winding drum rotates to the top to continue winding the plastic film. The winding drum on the lower winding roller 9 can be removed and replaced with a new winding drum. This operation greatly saves the time wasted during the replacement of the winding drum and avoids the waste of a large amount of plastic film due to not being wound.
