[0001] This utility model relates to the field of plastic bottle recycling technology, and in particular to a plastic bottle recycling flattening device. Background Technology

[0002] During the production and processing of plastic bottles, a lot of plastic bottle waste is generated that needs to be recycled. At the same time, there are a large number of waste plastic bottles on the market that need to be recycled. When recycling plastic bottles, a flattening device is needed to flatten the waste plastic bottles.

[0003] For example, CN208277497U discloses a flattening device for recycling plastic bottles. Vertical channel steel is fixedly connected to both sides of the base platform. A horizontal plate is welded between the top ends of the vertical channel steel on both sides. A hydraulic cylinder is installed at the center of the horizontal plate. A pressing plate is fixedly connected to the telescopic rod end of the hydraulic cylinder. Guide holes are opened on both sides of the pressing plate. A guide rod is inserted into the opened guide holes. The top end of the guide rod is fixedly connected to the bottom surface of the horizontal plate.

[0004] In existing technologies, recycled waste plastic bottles may not be completely emptied, resulting in incomplete flattening and high rebound force due to gas expansion during compression. Residual liquid splashes and contaminates the equipment. When the emptied bottles are compressed, the compressed bottle blocks are loose and prone to springing back due to gas expansion, requiring secondary compression and affecting the flattening efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art where recycled waste plastic bottles may not be emptied, resulting in incomplete flattening, large rebound force, residual liquid splashing and contamination of the equipment, and affecting flattening efficiency. Therefore, a plastic bottle recycling and flattening device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a plastic bottle recycling and flattening device, comprising a mounting frame, the mounting frame consisting of an upper base plate, a lower base plate and four connecting columns, the four connecting columns being fixed between the upper base plate and the lower base plate, a recycling mechanism being installed on the top of the lower base plate, a flattening mechanism being provided above the recycling mechanism, the flattening mechanism comprising a pressing plate, a fixing rod being fixedly connected to the top of the pressing plate, a push plate being fixedly connected to the top of the fixing rod, a telescopic rod being fixedly connected to the bottom side of the push plate, a moving plate being fixedly connected to one end of the telescopic rod, a compression spring being installed between the moving plate and the push plate, the compression spring being sleeved on the outside of the telescopic rod, and a metal needle being fixedly connected to the bottom side of the moving plate, one end of the metal needle passing through the pressing plate.

[0007] Preferably, a second push block is fixedly connected to the top side of the movable plate, and a first push block is abutted on both sides of the second push block. A guide rail is slidably connected to the top side of the first push block, and one side of the guide rail is fixedly connected to the bottom side of the push plate.

[0008] Preferably, a drive motor is fixedly connected to the bottom side of the push plate, and a threaded rod is fixedly connected to the output end of the drive motor. The other end of the threaded rod is rotatably connected to the push plate, and the two sides of the middle part of the threaded rod are threadedly connected to two first push blocks respectively.

[0009] Preferably, the pressure plate has a perforation, through which a metal needle passes.

[0010] Preferably, the recycling mechanism includes a flattening frame with multiple water filter holes on the bottom side. Electric push rods are fixedly connected to both sides of the flattening frame, and a connecting plate is fixedly connected to one end of each electric push rod. The connecting plate is slidably connected to the outer side of the flattening frame.

[0011] Preferably, the bottom of the flattening frame is fixedly connected to the top of the bottom plate, and a guide frame is fixedly connected to the bottom side of the flattening frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the drive motor drives the threaded rod to rotate, and the two first push blocks move, pushing the second push block downward, which in turn moves the moving plate and adjusts the extension length of the metal needle through the hole. When the hydraulic cylinder pushes the push plate downward, the metal needle first contacts the plastic bottle and pierces the bottle body, releasing the internal gas and residual liquid. The drive motor moves in the opposite direction, driving the end of the metal needle to extend into the inside of the hole. The pressing plate continues to move to complete the flattening operation of the plastic bottle, preventing the metal needle from interfering with the flattening of the plastic bottle, reducing the rebound force and liquid splashing during flattening, and improving the flattening effect and equipment cleanliness.

[0014] 2. In this utility model, when the flattening is flattened, the liquid in the bottle can flow into the lower guide frame through the water filter hole on the bottom side of the flattening frame to achieve centralized collection of liquid. The hydraulic cylinder drives the flattening mechanism to move upward and reset, and the electric push rod extends to push the connecting plate to slide along the outside of the flattening frame, pushing the flattened plastic sheet out of the flattening frame to achieve automatic unloading and improve efficiency.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a plastic bottle recycling and flattening device, including a mounting frame 1. The mounting frame 1 consists of an upper base plate, a lower base plate, and four connecting columns. The four connecting columns are fixed between the upper base plate and the lower base plate. A recycling mechanism 2 is installed on the top of the lower base plate, and a flattening mechanism 3 is arranged above the recycling mechanism 2. The flattening mechanism 3 includes a pressing plate 31. A fixing rod 311 is fixedly connected to the top of the pressing plate 31. A push plate 32 is fixedly connected to the top of the fixing rod 311. A telescopic rod 33 is fixedly connected to the bottom side of the push plate 32. A moving plate 35 is fixedly connected to one end of the telescopic rod 33. A compression spring 312 is installed between the moving plate 35 and the push plate 32. The compression spring 312 is sleeved on the outside of the telescopic rod 33. A metal needle 34 is fixedly connected to the bottom side of the plate 35, and one end of the metal needle 34 passes through the pressure plate 31. A second push block 310 is fixedly connected to the top side of the moving plate 35. Both sides of the second push block 310 abut against the first push block 37. A guide rail 38 is slidably connected to the top side of the first push block 37. One side of the guide rail 38 is fixedly connected to the bottom side of the push plate 32. A drive motor 36 is fixedly connected to the bottom side of the push plate 32. A threaded rod 39 is fixedly connected to the output end of the drive motor 36. The other end of the threaded rod 39 is rotatably connected to the push plate 32. The two sides of the middle part of the threaded rod 39 are threadedly connected to the two first push blocks 37 respectively. A through hole 313 is opened on the pressure plate 31, and the metal needle 34 passes through the inside of the through hole 313.

[0020] Start the drive motor 36 to rotate the threaded rod 39. Since the threaded connection directions on both sides of the middle of the threaded rod 39 are opposite, the two first push blocks 37 will move towards or away from each other along the guide rail 38. When the first push block 37 moves to the point where its inclined surface contacts the inclined surface of the second push block 310, it pushes the second push block 310 downward, causing the moving plate 35 to move. Adjust the extension length of the metal needle 34 through the through hole 313 on the pressure plate 31. The telescopic rod 33 provides guidance for the moving plate 35, and the compression spring 312 plays a buffering and protective role. When the hydraulic cylinder 4 pushes the push plate 32 downward... As the pressure plate 31 moves downward, the metal needle 34 first contacts the plastic bottle and pierces the bottle body, releasing the internal gas and residual liquid. Then the pressure plate 31 continues to move downward, while the drive motor 36 moves in the opposite direction, causing the first push block 37 to separate from the second push block 310. The deformed compression spring 312 drives the metal needle 34 to move upward until its end extends into the interior of the perforation 313. The pressure plate 31 continues to move to complete the flattening operation of the plastic bottle, preventing the metal needle 34 from interfering with the flattening of the plastic bottle, reducing the rebound force and liquid splashing during flattening, and improving the flattening effect and equipment cleanliness.

[0021] Example 2: Figure 1 and Figure 4As shown, the recycling mechanism 2 includes a flattening frame 24, with multiple filter holes on the bottom side of the flattening frame 24. Electric push rods 22 are fixedly connected to both sides of the flattening frame 24. One end of the electric push rod 22 is fixedly connected to a connecting plate 21, and the connecting plate 21 is slidably connected to the outer side of the flattening frame 24. The bottom of the flattening frame 24 is fixedly connected to the top of the lower base plate, and a guide frame 23 is fixedly connected to the bottom side of the flattening frame 24. The four corners of the push plate 32 are slidably connected to the outside of four connecting columns, and a hydraulic cylinder 4 is fixedly connected to the top side of the upper base plate. One end of the hydraulic cylinder 4 passes through the upper base plate and is fixedly connected to the top side of the push plate 32.

[0022] The plastic bottle to be flattened is placed in the flattening frame 24. If there is residual liquid in the plastic bottle, the liquid can flow into the lower guide frame 23 through the water filter hole on the bottom side of the flattening frame 24 during the flattening process, so as to achieve centralized collection of liquid. The hydraulic cylinder 4 is started, which drives the push plate 32 to slide down along the four connecting columns of the mounting frame 1, thereby driving the flattening mechanism 3 to move down as a whole. The pressing plate 31 flattens the plastic bottle in the flattening frame 24. After flattening, the hydraulic cylinder 4 drives the flattening mechanism 3 to move up and reset. The electric push rod 22 extends and pushes the connecting plate 21 to slide along the outside of the flattening frame 24, pushing the flattened plastic sheet out of the flattening frame 24, thereby achieving automatic unloading and improving efficiency.

[0023] The operating method and working principle of this device are as follows: Start the drive motor 36, which rotates the threaded rod 39. The two first push blocks 37 will move towards or away from each other along the guide rail 38, causing the second push block 310 to move. Adjust the extension length of the metal needle 34 through the through hole 313 on the pressing plate 31, and place the plastic bottle to be recycled into the pressing frame 24 to complete the loading. Start the hydraulic cylinder 4, which pushes the push plate 32 downwards along the four connecting columns of the mounting frame 1, causing the pressing mechanism 3 to move downwards as a whole. The metal needle 34 first contacts the plastic bottle, piercing the bottle body and releasing the residual gas or liquid inside. The liquid flows into the lower guide frame 23 through the filter hole on the bottom side of the flattening frame 24, achieving centralized collection of the liquid. After the metal needle 34 pierces the plastic bottle, the drive motor 36 moves in the opposite direction, driving the metal needle 34 to move upward until its end extends into the interior of the perforation 313. The flattening plate 31 continues to move downward, applying pressure to the plastic bottle and flattening it into a plastic sheet. The hydraulic cylinder 4 drives the push plate 32 to move upward, causing the flattening mechanism 3 to reset. The electric push rod 22 is activated, pushing the connecting plate 21 to slide along the outside of the flattening frame 24, pushing the flattened plastic sheet out of the flattening frame 24, completing the unloading and facilitating subsequent collection and transportation.
