[0018] 4. The bottle body and bottle cap of plastic bottles are made of different materials and need to be recycled separately. The conveyor belt sends the broken plastic pieces into the water tank. The bottle body fragments sink to the bottom of the water, and the bottle cap fragments and some remaining label fragments float on the water surface. In the process of conveying plastic pieces on the conveyor belt, the swing fork plate swings upward continuously to fork up the bottle cap fragments and label fragments on the water surface.

DETAILED DESCRIPTION

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] Embodiment 1: A plastic product recycling device, such as Figure 1-Figure 10As shown, it includes a label removing cylinder 2, an inner lining cylinder 2001, a sliding plate 201, a return spring 202, a scraper 203, a rotating conveying mechanism and a crushing mechanism. The inner lining cylinder 2001 is fixedly connected to the label removing cylinder 2, and the sliding plate 201 is slidably connected to the outside of the label removing cylinder 2 through a guide rod. The scraper 203 is fixedly connected to the sliding plate 201. The end of the scraper 203 away from the sliding plate 201 passes through the label removing cylinder 2 and is located on the inner side of the inner lining cylinder 2001. The sliding plate 201 and the label removing cylinder 2 are connected through the return spring 202. One end of the return spring 202 is fixedly connected to the sliding plate 201, and the other end is fixedly connected to the guide rod outside the label removing cylinder 2. The rotating conveying mechanism is installed in the inner lining cylinder 2001. The rotating conveying mechanism drives the plastic bottles put into the inner lining cylinder 2001 to rotate and gradually move downward. The crushing mechanism is arranged below the label removing cylinder 2, and the crushing mechanism crushes the plastic bottles with labels removed.

[0032] The flattened plastic bottles are put into the label removal cylinder 2 from the top, and the rotating conveying mechanism is driven by an external device. During the operation of the rotating conveying mechanism, the plastic bottles are driven to rotate in the inner liner cylinder 2001. The plastic bottles come into contact with the scraper 203 during the movement, and the scraper 203 scrapes off the labels on the plastic bottles. As the rotating conveying mechanism continues to operate, the plastic bottles put into the label removal cylinder 2 fall downward into the crushing mechanism, and the crushing mechanism crushes the plastic bottles with the labels removed.

[0033] Embodiment 2: Based on embodiment 1, Figure 1-Figure 5 As shown, the rotating conveying mechanism includes a rotating cylinder 204, a movable fan plate 205, a return spring 2051 and an alternating support assembly. A support plate is provided on the top of the label removal cylinder 2, and the rotating cylinder 204 is rotatably connected to the support plate on the top of the label removal cylinder 2. The movable fan plate 205 is slidably connected in the rotating cylinder 204. Small blades are installed on the upper and lower surfaces of the movable fan plate 205 and the inner surface of the liner cylinder 2001 to cooperate with the scraper 203 to remove the labels adhered to the plastic bottles during the rotation process. The movable fan plate 205 and the rotating cylinder 204 are connected by the return spring 2051. One end of the return spring 2051 is fixed on the movable fan plate 205, and the other end is fixed in the rotating cylinder 204. The alternating support assembly is installed on the rotating cylinder 204, and the alternating support assembly is used to push the movable fan plate 205 to slide out of the rotating cylinder 204 alternately.

[0034] The external device drives the rotating cylinder 204 to rotate. When the rotating cylinder 204 rotates, the moving fan plate 205 rotates accordingly, and the plastic bottles on the moving fan plate 205 rotate accordingly. During the rotation of the plastic bottles, they come into contact with the scraper 203, and the scraper 203 removes the labels on the surfaces of the plastic bottles. During the rotation of the rotating cylinder 204, the alternating support assembly cooperates with the return spring 2051, so that the moving fan plates 205 at different heights continuously slide back and forth along the rotating cylinder 204. When the moving fan plate 205 at a higher position slides into the rotating cylinder 204, the moving fan plate 205 at a slightly lower level will slide out of the rotating cylinder 204. At this time, the plastic bottles on the moving fan plate 205 at a higher position will fall downward. Under the action of the alternating support assembly and the return spring 2051, the moving fan plate 205 slides back and forth along the rotating cylinder 204 and continuously transfers the plastic bottles downward.

[0035] like Figure 3-Figure 5 As shown, the alternating support assembly includes a transposition platform 2042, a guide rod 206, a lifting frame 207, a wedge-shaped push block 2071 and a fixed slider 2072. The transposition platform 2042 is fixedly connected to the rotating cylinder 204, the guide rod 206 is fixedly connected to the outside of the mark removal cylinder 2, the lifting frame 207 is slidably connected to the guide rod 206, the central round rod of the lifting frame 207 is located in the rotating cylinder 204, and the top of the lifting frame 207 is fixedly connected to the fixed slider 2072 near the transposition platform 2042. The fixed slider 2072 is connected to the transposition platform 2042. The surface of the positioning platform 2042 is in contact with the rotating cylinder 204. The positioning platform 2042 pushes the lifting frame 207 to move up and down through the fixed slider 2072 during the rotation of the rotating cylinder 204. The round rod of the lifting frame 207 is fixed with a wedge-shaped push block 2071. The number of the wedge-shaped push blocks 2071 is the same as the number of layers of the movable fan plate 205. During the up and down movement of the lifting frame 207, the movable fan plate 205 is alternately pushed to extend outward from the rotating cylinder 204, so that the plastic bottle gradually falls downward during the process of removing the label on the plastic bottle.

[0036] The movable fan plates 205 on the rotating cylinder 204 are divided into multiple layers, and the height of each layer of movable fan plates 205 is consistent. The wedge-shaped push blocks 2071 on the round rod of the lifting frame 207 are divided into two types, one facing upward and the other facing downward. The states of two adjacent wedge-shaped push blocks 2071 are different. In the initial state, the lifting frame 207 is located at a low position. At this time, the downward wedge-shaped push blocks 2071 contact the movable fan plates 205 with an even number of layers and push them out of the rotating cylinder 204. The return springs 2051 at the corresponding positions are compressed. During the rotation of the rotating cylinder 204, the transposition table 2042 rotates accordingly. When the inclined surface on the transposition table 2042 contacts the fixed slider 2072, the fixed slider 2072 and the lifting frame 207 will move along the transposition table 2042. The inclined surface rises, and when the lifting frame 207 rises to a high position, the upward wedge-shaped push block 2071 contacts the moving fan plates 205 with an odd number of layers from top to bottom and pushes them out of the rotating cylinder 204, and the downward wedge-shaped push block 2071 disengages from the other half of the moving fan plates 205. At this time, the return springs 2051 of the even number of layers push the moving fan plates 205 of the even number of layers to slide and reset along the rotating cylinder 204, and the plastic bottles on the moving fan plates 205 of the even number of layers will fall downward. During the rotation of the rotating cylinder 204, the lifting frame 207 continuously moves up and down, so that the moving fan plates 205 of the odd number of layers and the even number of layers continuously slide back and forth along the rotating cylinder 204, thereby causing the plastic bottles to continuously fall, thereby realizing the function of conveying the plastic bottles downward.

[0037] like Figure 2 As shown, it also includes a label extraction tube 2002 and a curved rod 2041. The label extraction tube 2002 is fixedly connected to the label removal cylinder 2. The end of the label extraction tube 2002 passes through the inner lining cylinder 2001. The label extraction tube 2002 extracts the label peeled off the plastic bottle. A ring rod is fixedly connected to the rotating cylinder 204. The curved rod 2041 is fixedly connected to the ring rod of the rotating cylinder 204. During the rotation of the rotating cylinder 204, the sliding plate 201 is pushed to slide outward along the label removal cylinder 2 through the curved rod 2041, so that the scraper 203 slides along the label removal cylinder 2, and the label wrapped around the scraper 203 is removed when the label removal cylinder 2 is lowered.

[0038] During the process of removing the label on the plastic bottle, the label extraction tube 2002 draws air outward from the inner liner tube 2001, and the label peeled off the plastic bottle is extracted outward by the label extraction tube 2002 along with the airflow. During the rotation of the rotating cylinder 204, the arc rods 2041 on the ring rods at the upper and lower ends of the rotating cylinder 204 rotate accordingly. During the movement of the arc rods 2041, they will contact the sliding plate 201 and push it to slide in the direction away from the label removal cylinder 2. During the sliding of the sliding plate 201, the scraper 203 is driven to move and compress the return spring 202. During the movement of the scraper 203, the label wrapped around the scraper 203 is blocked by the label removal cylinder 2 to remove the label wrapped around the scraper 203. After the arc rod 2041 is out of contact with the sliding plate 201, the return spring 202 pushes the sliding plate 201 to slide in the direction close to the label removal cylinder 2, and the scraper 203 on the sliding plate 201 moves accordingly and re-enters the inner liner tube 2001.

[0039] Embodiment 3: Based on embodiment 2, Figure 6-Figure 8 As shown, the crushing mechanism includes a base frame 1, a crushing baffle 101, a screen plate 1011, a crushing shaft 102, a transmission shaft 103, a first belt transmission member 104, a second belt transmission member 105, a receiving tray 301 and a receiving assembly. The base frame 1 is provided below the label removal cylinder 2, the crushing baffle 101 is fixedly connected inside the base frame 1, the left end of the base frame 1 and the crushing baffle 101 together form a circular frame, the base frame 1 is fixedly connected to the receiving tray 301, the receiving tray 301 is located directly below the label removal cylinder 2, the bottom of the receiving tray 301 is rotatably connected to the crushing shaft 102, and the base frame 1 and the crushing baffle 101 are rotatably connected to the screen plate 301. Plate 1011, the crushing shaft 102 is fixedly connected to the screen plate 1011, the crushing baffle 101 is rotatably connected to the transmission shaft 103 outside, the transmission shaft 103 and the crushing shaft 102 are connected through the first belt transmission member 104, the transmission shaft 103 and the rotating cylinder 204 are connected through the second belt transmission member 105, the rotating cylinder 204 drives the crushing shaft 102 to rotate through the second belt transmission member 105, the transmission shaft 103 and the first belt transmission member 104 to crush the plastic bottles after the labels are removed, and the receiving component is installed on the receiving tray 301, and the receiving component is used to prevent the plastic bottles from being blocked on the receiving tray 301.

[0040] When the plastic bottles fall from the bottom-level moving fan plate 205, they will fall onto the receiving tray 301. When the lifting frame 207 rises, it drives the receiving assembly to run, so as to push the plastic bottles on the receiving tray 301 into between the base frame 1 and the crushing baffle 101. When the rotating cylinder 204 rotates, the crushing shaft 102 is driven to rotate through the second belt transmission member 105, the transmission shaft 103 and the first belt transmission member 104. A crushing knife is installed on the crushing shaft 102. The plastic bottles passing through the receiving tray 301 are shredded by the crushing knife on the crushing shaft 102. The screen plate 1011 screens the plastic bottles during the rotation of the crushing shaft 102, and the crushed plastic flakes fall downward through the screen plate 1011.

[0041] like Figure 7 and Figure 8 As shown, the receiving assembly includes a fixed round rod 2073, a rotating frame 3, a toggle rod 302 and a material blocking fan plate 303. The receiving tray 301 is rotatably connected with the rotating frame 3. The rotating frame 3 is fixedly connected to the toggle rod 302. The toggle rod 302 is located above the receiving tray 301. The receiving tray 301 is rotatably connected with the material blocking fan plate 303. The rotating frame 3 is fixedly connected to the material blocking fan plate 303. The material blocking fan plate 303 blocks the fan-shaped through hole on the receiving tray 301. The bottom end of the round rod is fixedly connected to the fixed round rod 2073, and an arc-shaped slide is opened on the rotating frame 3. The fixed round rod 2073 is located in the arc-shaped slide on the rotating frame 3. When the lifting frame 207 rises, it drives the fixed round rod 2073 to rise. When the fixed round rod 2073 rises, it drives the rotating frame 3 to rotate and makes the blocking fan plate 303 turn away from the fan-shaped through hole on the receiving tray 301, so that the unlabeled plastic bottles that fall on the receiving tray 301 fall between the base frame 1 and the crushing baffle 101.

[0042] When the lifting frame 207 rises, it drives the rotating frame 3 to rotate through the fixed round rod 2073. When the rotating frame 3 rotates, it drives the material blocking fan plate 303 to slide away from the fan-shaped through hole on the receiving tray. The toggle rod 302 on the rotating frame 3 stirs the plastic bottles on the receiving tray 301 during the rotation process to prevent the plastic bottles from getting stuck in the fan-shaped through hole on the receiving tray 301.

[0043] like Fig. 9 and Fig.10As shown, it also includes a receiving plate 4, a conveyor belt 401, a positioning rod 402, a rotating shaft 403, a bevel gear transmission group 404, a missing gear 405, a rotating gear 406, a swing fork plate 407 and a water tank 408. The receiving plate 4 is fixedly connected to the base frame 1, and the receiving plate 4 is located below the screen plate 1011. The conveyor belt 401 is installed in the base frame 1. The receiving plate 4 is in an inclined state and connected to the conveyor belt 401. The positioning rod 402 is fixedly connected to the base frame 1, and the positioning rod 402 is pressed on both ends of the conveyor belt 401 to limit its shape. The water tank 408 is fixedly connected to the base frame 1, and the rotating shaft 403 is rotatably connected to the water tank 408. The rotating shaft 403 is connected to the roller of the conveyor belt 401 through the bevel gear transmission group 404. When the conveyor belt 401 is running, the rotating shaft 4 is driven by the bevel gear transmission group 404. 03 rotates, the other end of the rotating shaft 403 is fixedly connected to the missing gear 405, and a swing fork plate 407 is rotatably connected in the water tank 408. The insertion rods on the two swing fork plates 407 are staggered to ensure that when the two swing fork plates 407 swing upward, all the bottle cap fragments or residual label fragments floating on the water surface of the water tank 408 are picked up. The rotating shaft of the swing fork plate 407 passes through the water tank 408 and is fixedly connected to the rotating gear 406. When the missing gear 405 rotates, it can mesh with the rotating gear 406. Every rotation of the missing gear 405 can drive the rotating gear 406 and the swing fork plate 407 to rotate 150 degrees to pick up the plastic bottle cap fragments on the water surface. When the missing gear 405 is out of contact with the rotating gear 406, the rotating gear 406 and the swing fork plate 407 are affected by gravity and swing downward to reset.

[0044] After the plastic bottles are broken, the plastic flakes are formed and fall onto the receiving plate 4 and the conveyor belt 401 through the sieve plate 1011. The plastic flakes on the receiving plate 4 slide along its surface onto the conveyor belt 401. When the conveyor belt 401 is running, the broken plastic flakes are sent into the water tank 408. Due to the different types of plastics used for the bottle body and the bottle cap, when the broken plastic flakes fall into the water, the bottle cap fragments and the label fragments remaining on the plastic bottle will float on the water surface, and the broken fragments of the plastic bottle body will sink to the bottom of the water. During the operation of the conveyor belt 401, the rotating shaft 403 and the missing gear 4 are driven by the bevel gear transmission group 404. 05 rotates, and when the missing gear 405 rotates, it drives the swing fork plate 407 to swing upward through the rotating gear 406. The two swing fork plates 407 swing upward to pick up the bottle cap fragments and label fragments on the water surface. When the swing fork plates 407 swing upward more than 120 degrees, the bottle cap fragments and label fragments will slide downward along the swing fork plates 407 to the collecting plates on both sides of the water tank 408. When the missing gear 405 is out of contact with the rotating gear 406, under the action of the gravity of the swing fork plates 407, the swing fork plates 407 swing downward to reset, thereby realizing the function of picking out the bottle cap fragments and label fragments.
