DETAILED DESCRIPTION

[0023] The present invention is further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 2 As shown, the structure and function of bidirectional disintegration type degradable plastics are described in detail below;

[0025] A bidirectional disintegrating degradable plastic comprises an inner plate 11 and clamping plates 12 covering both sides of the inner plate 11, side plates 13 are arranged on the outer sides of the two clamping plates 12, a plurality of arc cavities 14 are arranged in the inner plate 11, a plurality of connecting holes 15 are arranged on each clamping plate 12, the plurality of connecting holes 15 are respectively connected to the plurality of arc cavities 14, and the arc cavities 14 are in a vacuum;

[0026] When using, Figure 1As shown, the overall appearance of the bidirectional disintegrating degradable plastic is the same as that of normal plastic, and the surface is flat, which can ensure that the bidirectional disintegrating degradable plastic can be used like normal plastic. During degradation, the bidirectional disintegrating degradable plastic is placed in the degradation agent, and the degradation agent first contacts the side plate 13, which is relatively thin. After the side plate 13 is quickly degraded, the connecting hole 15 is exposed, and the connecting hole 15 is connected to the arc cavity 14. The arc cavity 14 is vacuum, and the arc cavity 14 quickly absorbs the degradation agent into the arc cavity 14. A plurality of arc cavities 14 are arranged on the inner plate 11, and each arc cavity 14 is sucked with a degradation agent, so that the degradation agent starts to degrade the entire bidirectional disintegrating degradable plastic from the inner plate 11. The arc cavity 14 not only increases the contact area between the degradation agent and the bidirectional disintegrating degradable plastic, but also makes the degradation agent degrade the bidirectional disintegrating degradable plastic inside, thereby accelerating the degradation speed of the bidirectional disintegrating degradable plastic, and the bidirectional disintegrating degradable plastic can be used like normal plastic.

[0027] Since the arc cavity 14 needs to be a vacuum structure, the preparation process of the degradable plastic is relatively complicated, so a degradable plastic processing device is designed to process the degradable plastic;

[0028] A degradable plastic processing device comprises a device bracket 21, a plurality of rotating wheels 22 are rotatably connected to the device bracket 21, and four supporting brackets 23 are fixedly connected to the device bracket 21;

[0029] When using, Figure 3 As shown, the bidirectional disintegrating type degradable plastic is placed on a plurality of rotating wheels 22, and the plurality of rotating wheels 22 can support the bidirectional disintegrating type degradable plastic, and the plurality of rotating wheels 22 can rotate, so as to facilitate the movement of the bidirectional disintegrating type degradable plastic on the device;

[0030] A screw rod 31 is rotatably connected to the device bracket 21, and a power mechanism I for driving the screw rod 31 to rotate is fixedly connected to the device bracket 21. The power mechanism I is preferably a servo motor. The threads at both ends of the screw rod 31 have opposite rotation directions. Both ends of the screw rod 31 are connected to clamping brackets 32 through threads. Both clamping brackets 32 are slidably connected to the device bracket 21. Both clamping brackets 32 are rotatably connected to multiple clamping wheels 33. The multiple clamping wheels 33 are transmission-connected. A power mechanism II for driving one of the clamping wheels 33 to rotate is fixedly connected to the clamping bracket 32. The power mechanism II is preferably a servo motor.

[0031] Start the power mechanism I, the output shaft of the power mechanism I starts to rotate, the output shaft of the power mechanism I drives the screw rod 31 to rotate, when the screw rod 31 rotates, it drives the two clamping brackets 32 to move through the thread, the two clamping brackets 32 approach each other, the two clamping brackets 32 drive the multiple clamping wheels 33 to approach each other, the multiple clamping wheels 33 clamp the side of the bidirectional disintegrating type degradable plastic, start the power mechanism II, the output shaft of the power mechanism II starts to rotate, the output shaft of the power mechanism II drives the clamping wheels 33 to rotate, the multiple clamping wheels 33 are connected by transmission, and then the multiple clamping wheels 33 rotate, the multiple clamping wheels 33 contact the side of the bidirectional disintegrating type degradable plastic, and then push the bidirectional disintegrating type degradable plastic to move on the device, so that the bidirectional disintegrating type degradable plastic passes through the lower ends of the multiple punching tools 52 and the multiple extraction cannulas 72 in sequence;

[0032] A lifting bracket Ⅰ41 is slidably connected between the two supporting brackets 23 located at the rear side, a spring Ⅰ is fixedly connected between the lifting bracket Ⅰ41 and the supporting bracket 23, a first telescopic mechanism 42 is fixedly connected to the lifting bracket Ⅰ41, a mounting bracket Ⅰ43 is fixedly connected to the telescopic end of the first telescopic mechanism 42, a plurality of rotating cylinders 51 are rotatably connected to the mounting bracket Ⅰ43, the plurality of rotating cylinders 51 are transmission-connected, a power mechanism III for driving one of the rotating cylinders 51 to rotate is fixedly connected to the mounting bracket Ⅰ43, the power mechanism III is preferably a servo motor, a punching tool 52 is fixedly connected to the lower end of each rotating cylinder 51, a water injection pipe 53 is rotatably connected to the upper end of each rotating cylinder 51, a second telescopic mechanism 54 is fixedly connected to the lifting bracket Ⅰ41, a plurality of sealing columns 55 are fixedly connected to the telescopic end of the second telescopic mechanism 54, the plurality of sealing columns 55 are respectively inserted into the plurality of punching tools 52, and the punching tools 52 are hollow structures;

[0033] A lifting bracket II 61 is slidably connected between the two support brackets 23 located at the front side, a spring II is fixedly connected between the lifting bracket II 61 and the support bracket 23, a third telescopic mechanism 62 is fixedly connected to the lifting bracket II 61, a mounting bracket II 63 is fixedly connected to the telescopic end of the third telescopic mechanism 62, a plurality of extraction pipes 71 are fixedly connected to the mounting bracket II 63, an extraction cannula 72 is fixedly connected to the lower end of each extraction pipe 71, the extraction cannula 72 is communicated with the extraction pipe 71, a sliding cylinder 73 is slidably connected to each extraction cannula 72, a spring III is fixedly connected between the sliding cylinder 73 and the extraction cannula 72, an injection pipe 74 is fixedly connected to the sliding cylinder 73, a closed suction cup 75 is fixedly connected to the sliding cylinder 73, the closed suction cup 75 is made of elastic material, and the injection pipe 74 is communicated with the closed suction cup 75 through the injection hole 76;

[0034] When the bidirectional disintegrating biodegradable plastic moves to the lower end of the plurality of punching cutters 52, the first telescopic mechanism 42 is started. The first telescopic mechanism 42 may be a hydraulic cylinder or an electric push rod. The telescopic end of the first telescopic mechanism 42 drives the mounting bracket I 43 to move downward, and the mounting bracket I 43 drives the plurality of punching cutters 52 to move downward, so that the punching cutters 52 are in contact with the side plate 13.

[0035] The power mechanism III is started in advance, and the output shaft of the power mechanism III starts to rotate. The output shaft of the power mechanism III drives the rotating cylinder 51 to rotate. The multiple rotating cylinders 51 are connected by transmission, and the multiple rotating cylinders 51 rotate together. The rotating cylinder 51 drives the punching tool 52 to rotate. At the same time, the second telescopic mechanism 54 is started. The second telescopic mechanism 54 can be a hydraulic cylinder or an electric push rod. The telescopic end of the second telescopic mechanism 54 drives the sealing column 55 to move, so that the sealing column 55 is always inserted into the punching tool 52 to ensure that the bottom of the punching tool 52 is closed. When the punching tool 52 contacts the bidirectional disintegrating biodegradable plastic, the punching tool 52 punches holes on the side plate 13;

[0036] During the process of the punching tool 52 rotating to punch the side plate 13, since the lifting bracket Ⅰ41 is slidably connected between the two supporting brackets 23, the lifting bracket Ⅰ41 slides between the two supporting brackets 23, thereby ensuring that the bidirectional disintegrating degradable plastic and the punching tool 52 move forward together, ensuring the processing efficiency of the punching, that is, during the process of the bidirectional disintegrating degradable plastic moving forward, the punching tool 52 can still punch the side plate 13;

[0037] A plurality of punching tools 52 punch holes in the side plate 13, and the holes punched by the punching tools 52 are connected to the connecting holes 15. After the punching is completed, the second telescopic mechanism 54 is started, and the telescopic end of the second telescopic mechanism 54 drives the sealing column 55 to move, so that the sealing column 55 leaves the punching tool 52. The water pipe is pre-connected to the water injection pipe 53, and water is injected into the rotating cylinder 51 through the water injection pipe 53, and then injected into the arc cavity 14 and the connecting hole 15 through the punching tool 52;

[0038] Then, the bidirectional disintegrating type degradable plastic passes through a plurality of punching cutters 52, so that water is injected into the arc cavity 14 and the connecting hole 15 on the bidirectional disintegrating type degradable plastic;

[0039] When the multiple punching tools 52 are withdrawn, the lifting bracket I 41 is reset under the action of the spring I to prepare for subsequent processing;

[0040] When the bidirectional disintegrating degradable plastic moves to the lower end of the plurality of extraction cannulas 72, the third telescopic mechanism 62 is started. The third telescopic mechanism 62 may be a hydraulic cylinder or an electric push rod. The telescopic end of the third telescopic mechanism 62 drives the mounting bracket II 63 to move. The mounting bracket II 63 moves downward. The mounting bracket II 63 drives the plurality of extraction cannulas 72 to move downward, so that the plurality of extraction cannulas 72 are inserted into the holes punched by the plurality of punching tools 52, and then the plurality of extraction cannulas 72 are inserted into the plurality of arc cavities 14 through the plurality of connecting holes 15.

[0041] At the same time, when the telescopic end of the third telescopic mechanism 62 drives the extraction cannula 72 to move downward, the sliding cylinder 73 is pushed downward, and the sliding cylinder 73 drives the closed suction cup 75 to move downward, so that the closed suction cup 75 contacts the side plate 13, and the closed suction cup 75 is squeezed under the action of the spring III, so that the closed suction cup 75 covers the hole punched by the punching tool 52, that is, the closed suction cup 75 covers the outside of the hole punched by the punching tool 52;

[0042] An extraction pump is pre-connected to the extraction pipe 71, and then the extraction pump extracts all the water in the arc cavity 14 and the connecting hole 15 through the extraction cannula 72. At the same time, due to the sealing of the sealing suction cup 75, a vacuum environment is formed in the arc cavity 14 and the connecting hole 15.

[0043] The injection molding pipe is connected to the injection pipe 74 in advance. The injection molding material in the injection molding pipe is the same as the material of the side plate 13. At this time, the closed suction cup 75 is tightly attached to the side plate 13 after the extraction of the extraction tube 72, and the injection molding is passed into the closed suction cup 75. At this time, the extraction tube 72 is still inserted into the arc cavity 14. When the arc cavity 14 and the extraction tube 72 are separated, the closed suction cup 75 is still attached to the side plate 13 under the action of the spring III. Then, when the extraction tube 72 leaves the arc cavity 14, the closed suction cup 75 pushes the injection molding into the hole punched by the punching tool 52, and the hole punched by the punching tool 52 is blocked, thereby completing the processing of the bidirectional disintegrating degradable plastic.

[0044] At the moment when the extraction cannula 72 and the side plate 13 are separated, the closed suction cup 75 pushes the injection molded object into the hole punched by the punching tool 52. The diameter of the closed suction cup 75 is much larger than the diameter of the hole punched by the punching tool 52. A spring II is fixedly connected between the lifting bracket II 61 and the supporting bracket 23. In the process of spring II pushing the lifting bracket II 61 to reset, the closed suction cup 75 is still in contact with the side plate 13 for a period of time under the action of spring III. At the same time, the clamping wheel 33 drives the bidirectional disintegrating type biodegradable plastic to move forward for a short distance, and the clamping wheel 33 moves slowly, so that the distance that spring II pushes the lifting bracket II 61 to reset is less than the radius of the closed suction cup 75, that is, after the lifting bracket II 61 is reset, the closed suction cup 75 is still in contact with the side plate 13 for a period of time. During the reset movement of the lifting bracket II 61, the closed suction cup 75 is still in contact with the side plate 13, smoothing the upper surface of the side plate 13 to ensure the flatness of the side plate 13, and also giving the injection molded object some time to fix.
