Description

Technical Field

[0001] This invention relates to the field of plastic processing technology, and in particular to an environmentally friendly recycling device for processing plastic materials. Background Technology

[0002] Chinese patent CN118906313A discloses a device for crushing and recycling polypropylene plastic. When workers need to crush plastic parts, the plastic parts are poured into a crushing seat. Then, an electric push rod is driven to move the grinding hammer located on the lower side of the lifting seat at its movable end downward to a position close to the upper part of the crushing seat. This drives a second motor to rotate a rotating rod fixedly connected to its output shaft via a coupling. Consequently, two protrusions on the rotating rod rotate synchronously, repeatedly pushing the concave seats they contact. This causes a rectangular plate fixedly connected to each concave seat and a hammer seat fixedly connected below it to move downward synchronously, thereby repeatedly crushing the plastic parts in the crushing seat into powder.

[0003] However, during the hammering process, small plastic particles will adhere to the surface of the hammer seat. As the hammer seat moves back and forth, although the grinding hammer can scrape off the plastic particles adhering to the surface of the hammer seat, some of the scraped plastic particles remain at the junction of the grinding hammers. As the hammer seat moves back and forth, the plastic particles are easily carried into the space between the hammer seat and the grinding hammer. After the waste plastic in the crushing seat is crushed, it is necessary to manually clean the plastic particles carried into the space between the hammer seat and the grinding hammer. However, cleaning the plastic particles requires stopping the machine and disassembling the corresponding parts, which reduces the continuity of waste plastic crushing and is inconvenient to clean. Summary of the Invention

[0015] This invention has the following advantages: By creating an annular groove on the outside of the hammer holder, it provides a space to accommodate the small plastic particles brought between the hammer holder and the grinding seat, which helps reduce wear on the contact surfaces of the hammer holder and the grinding seat. After hammering, the invention first controls the cylinder to move the hammer holder downward until the annular groove is disengaged from the grinding seat. Then, it controls the delivery pump to deliver air into the cavity through the connecting pipe. The air is then ejected through the first exhaust channel, blowing the inside of the annular groove and quickly blowing the plastic particles remaining in the annular groove downward. Compared to existing methods that require removing the hammer holder from the grinding seat and cleaning the plastic particles attached to both the hammer holder and the grinding seat, this invention eliminates the need for manual removal of the hammer holder, allowing for convenient and quick cleaning of the plastic particles attached between the hammer holder and the grinding seat, ensuring continuous waste plastic crushing.

[0016] During grinding, an external air pump delivers cold air through a delivery pipe to the cold air flow channel on the grinding seat. The cold air flow channel then delivers the cold air to the cavity through the first air intake channel. The cold air in the cavity then passes through the first exhaust channel, the annular groove, and the second air intake channel into the exhaust pipe. Finally, it enters the second exhaust channel from the exhaust pipe and is blown out to the outside. In other words, the cold air flow channel cools the grinding seat and the hammer seat, ensuring stable grinding and preventing the temperature of the grinding seat and the hammer seat from rising, which would affect the grinding and crushing of the waste plastic, thus preventing the waste plastic from softening.

[0017] This invention integrates the cleaning and drying process into the grinding bucket, which can greatly reduce the overall size of the equipment, lower costs, and is more convenient and faster than existing equipment with external cleaning and drying processes, while also improving the continuous processing efficiency of waste plastics.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0028] Example 1

[0029] An environmentally friendly recycling device for processing plastic materials, such as Figures 1-6 As shown, it includes a fixed frame 1 and a mounting frame 2; the mounting frame 2 is connected to the fixed frame 1;

[0030] It also includes a hydraulic cylinder 101, a grinding seat 102, a grinding bucket 103, a pneumatic cylinder 104, a hammer seat 105, a connecting pipe 107, and a driver 1010; the fixed frame 1 is bolted to the hydraulic cylinder 101; the extension end of the hydraulic cylinder 101 is connected to the grinding seat 102; the mounting frame 2 is rotatably connected to the grinding bucket 103, which is located directly below the grinding seat 102, and the inner shape of the grinding bucket 103 matches the outer shape of the grinding seat 102; the grinding seat 102 has two sliding grooves 1021; several pneumatic cylinders 104 are fixedly connected to the grinding seat 102; each pneumatic cylinder 104 has a hammer seat 105 fixedly connected to its extension end, and the hammer seat 105 is in the corresponding sliding groove 1021. The internal sliding mechanism includes: an annular groove 1051 on each hammer base 105; a cavity 106 on each hammer base 105; a connecting pipe 107 fixedly connected to each hammer base 105, and the connecting pipe 107 communicating with the corresponding cavity 106; two first exhaust channels 108 on each hammer base 105, the first exhaust channels 108 communicating with the annular groove 1051 of the corresponding hammer base 105, and the communication position between the first exhaust channels 108 and the annular groove 1051 being located on the upper side of the annular groove 1051; a driver 1010 is bolted to the mounting bracket 2, the driver 1010 being a servo motor, and the output shaft of the driver 1010 being fixedly connected to the grinding bucket 103.

[0031] The lower side of the annular groove 1051 of the hammer seat 105 is provided with a beveled surface 1052. The lower side of the annular groove 1051 is flat, while the beveled surface can facilitate the air to clean up the debris and reduce the residue.

[0032] The outer side of the grinding seat 102, the inner side of the grinding bucket 103, and the bottom surface of the hammer seat 105 are all provided with rough textures to improve the grinding and crushing effect on waste plastics.

[0033] In this invention, the connecting pipe 107 is connected to an external delivery pump; initially, the bottom surface of the grinding seat 102 and the bottom surface of the hammer seat 105 together form a complete plane;

[0034] In use, the waste plastic to be ground and crushed is manually poured into the grinding hopper 103. Then, the driver 1010 is started, and the output shaft of the driver 1010 drives the grinding hopper 103 to rotate. Then, the hydraulic cylinder 101 drives the grinding seat 102 and its connecting parts to move vertically downward, so that the grinding seat 102 extends into the grinding hopper 103 until the grinding seat 102 contacts the waste plastic and grinds the waste plastic. When it is necessary to hammer and crush the waste plastic, the hydraulic cylinder 101 drives the grinding seat 102 to move downward and closer to the inside of the grinding hopper 103. Then, the air cylinder 104 drives the hammer seat 105 to move vertically back and forth, so that the hammer seat 105 hammers the plastic inside the grinding hopper 103 at high frequency.

[0035] Considering that during the hammering process, small plastic particles adhere to the outside of the hammer stand 105, some of these particles are carried into the space between the hammer stand 105 and the grinding stand 102 during the reciprocating movement of the hammer stand 105. Over time, this can easily cause wear on the contact surface between the hammer stand 105 and the grinding stand 102. Therefore, this invention provides an annular groove 1051 on the outside of the hammer stand 105 to accommodate the small plastic particles carried into the space between the hammer stand 105 and the grinding stand 102, thereby reducing wear on the contact surface between the hammer stand 105 and the grinding stand 102. It should be noted that during the reciprocating movement of the hammer stand 105, the annular groove 1051 of the hammer stand 105 is not connected to the outside, meaning that the plastic particles in the grinding bucket 103 will not be carried into the space between the hammer stand 105 and the grinding stand 102.

[0036] After the hammering is finished and the plastic powder in the grinding bucket 103 is manually removed, the plastic particles remaining in the annular groove 1051 need to be removed in time. In this invention, the cylinder 104 is first controlled to move the hammer seat 105 downward until the annular groove 1051 is disengaged from the grinding seat 102. Then, the conveying pump is controlled to deliver air into the cavity 106 through the connecting pipe 107. The air is then sprayed out through the first exhaust channel 108 to blow the inside of the annular groove 1051, quickly blowing the plastic particles and powder remaining in the annular groove 1051 downward. Compared with the existing method of removing the hammer seat 105 from the grinding seat 102 and cleaning and maintaining the plastic particles attached to the hammer seat 105 and the grinding seat 102, this invention does not require manual removal of the hammer seat 105. The plastic particles attached between the hammer seat 105 and the grinding seat 102 can be cleaned and maintained, which is convenient and quick, and ensures continuous crushing of waste plastics.

[0037] Example 2

[0038] Based on Example 1, such as Figures 4-6As shown, it also includes a conveying pipe 201, a cold air flow channel 202, and an exhaust pipe 203; the grinding base 102 is fixedly connected to the conveying pipe 201; a cold air flow channel 202 is opened inside the grinding base 102, and the conveying pipe 201 communicates with the cold air flow channel 202; each hammering base 105 has a first air intake channel 109, and the first air intake channel 109 communicates with the cold air flow channel 202, and the diameter of the first air intake channel 109 is larger than the diameter of the cold air flow channel 202; each hammering base 105 is fixedly connected to an L-shaped exhaust pipe. The air inlet of the air pipe 203 is located inside the cavity 106; the grinding seat 102 has two second exhaust channels 1022, and the second exhaust channels 1022 are connected to the corresponding exhaust outlets of the exhaust pipes 203, and the diameter of the second exhaust channels 1022 is larger than the diameter of the exhaust pipes 203; each hammer seat 105 has a second air inlet channel 204, which is connected to the annular groove 1051 and the cavity 106, and the second air inlet channel 204 is located below the first exhaust channel 108.

[0039] It also includes a flow divider 205; each hammer seat 105 is fixedly connected to a flow divider 205, and the flow divider 205 is located in the cavity 106, and the exhaust pipe 203 passes through the flow divider 205, and the flow divider 205 is located between the first exhaust channel 108 and the second intake channel 204.

[0040] Both the grinding seat 102 and the hammering seat 105 are made of metal with high thermal conductivity, which improves the cooling efficiency of the first exhaust channel 108.

[0041] In this embodiment, the connecting pipe 107 is not provided, the hammer seat 105 is a sealed configuration, and the cavity 106 is not connected to the outside. In this embodiment, the airflow for blowing away plastic granules and powder comes from the conveying pipe 201. The purpose of the conveying pipe 201 is to deliver cold air to the cold airflow channel 202 to cool the grinding seat 102 and the hammer seat 105. The conveying pipe 201 is connected to an external air pump. The specific principle is as follows:

[0042] When grinding and crushing waste plastic, the grinding seat 102 and the hammer seat 105 reciprocate and rub against the plastic, causing the temperature of the grinding seat 102 and the hammer seat 105 to rise. Therefore, during grinding, an external air pump delivers cold air to the cold air channel 202 through the delivery pipe 201. Then, the cold air channel 202 delivers cold air to the cavity 106 through the first air intake channel 109. Next, the cold air in the cavity 106 passes through the first exhaust channel 108, the annular groove 1051 and the second air intake channel 204 and enters the exhaust pipe 203. Finally, it enters the second exhaust channel 1022 from the exhaust pipe 203 and is blown out to the outside. That is, the grinding seat 102 and the hammer seat 105 are cooled by the cold air channel 202 to ensure stable grinding and avoid the temperature rise of the grinding seat 102 and the hammer seat 105 from affecting the grinding and crushing of waste plastic, that is, to prevent the waste plastic from softening.

[0043] During the hammering process of the hammer base 105, since the diameter of the first air intake channel 109 is larger than the diameter of the cold air flow channel 202, and the downward distance of the hammer base 105 is smaller than the diameter difference between the first air intake channel 109 and the cold air flow channel 202, the cold air in the cold air flow channel 202 can still normally enter the first air intake channel 109 during the hammering process to cool the hammer base 105. Also, since the diameter of the second exhaust channel 1022 is larger than the diameter of the exhaust pipe 203, the cold air in the exhaust pipe 203 can still normally enter the second exhaust channel 1022 during the hammering process.

[0044] During the cleaning and maintenance of the hammer seat 105, since the annular groove 1051 is dislodged from the grinding seat 102, the cold air passes through the first exhaust channel 108 and directly blows the inside of the annular groove 1051, quickly blowing out the plastic particles powder remaining in the annular groove 1051 downwards. It should be noted that during the grinding and hammering process, the annular groove 1051 is not connected to the outside. That is, after the cold air enters the annular groove 1051 through the first exhaust channel 108, the airflow is restricted and enters the exhaust pipe 203 through the second air intake channel 204 for discharge.

[0045] It should be noted that by setting a flow divider 205 in the cavity 106, the flow divider 205 is located between the first exhaust channel 108 and the second intake channel 204 in the cavity 106, so that the cold air in the cavity 106 will not be directly discharged through the exhaust pipe 203. This ensures that the cold air entering the cavity 106 can pass normally through the first exhaust channel 108, the annular groove 1051 and the second intake channel 204, ensuring the cooling effect on the hammer seat 105 and ensuring the effect of subsequent blowing on the inner side of the annular groove 1051.

[0046] Example 3

[0047] Based on Example 2, such as Figures 1-3 , Figure 7 and Figure 8As shown, it also includes a cleaning assembly, which includes a first connecting plate 301, a first electric push rod 302, a first annular push plate 303, a second connecting plate 304, a water pipe 305, a fixing ring 306, a drying pipe 307, a third connecting plate 308, a second electric push rod 309, and a second annular push plate 3010; the fixing frame 1 is fixedly connected to the first connecting plate 301 and the second connecting plate 304 through the fixing plate; the fixing frame 1 is fixedly connected to two first electric push rods 302 through the fixing plate; the telescopic ends of all the first electric push rods 302 are fixedly connected to a first annular push plate 303, the first annular push plate 303 is composed of an L-shaped base plate, a movable part 3031, and an elastic part 3032, the vertical part of the L-shaped base plate is rotatably connected to the movable part 3031, the horizontal part of the L-shaped base plate is fixedly connected to the elastic part 3032, and the other end of the elastic part 3032 is... The L-shaped base plate is fixedly connected to the active part 3031 and slidably connected to the first connecting plate 301 and the second connecting plate 304. A water pipe 305 is fixedly connected to the first connecting plate 301 and passes through the first connecting plate 301. A fixing ring 306 is fixedly connected to the side of the second connecting plate 304 away from the first connecting plate 301. Eight drying pipes 307 are fixedly connected to the fixing ring 306. A third connecting plate 308 is fixedly connected to the fixing ring 306. Two second electric push rods 309 are fixedly connected to the fixing plate through the fixing plate. The telescopic ends of all the second electric push rods 309 are fixedly connected to a second annular push plate 3010, which is located between the second connecting plate 304 and the third connecting plate 308. The drying pipes 307 pass through the fixing ring 306 and the second annular push plate 3010. The telescopic ends of the second electric push rods 309 pass through the fixing ring 306.

[0048] The upper side of the first connecting plate 301 is higher than the upper side of the second connecting plate 304, and the upper side of the second connecting plate 304 is higher than the upper side of the third connecting plate 308.

[0049] The upper surface of the second annular push plate 3010 is inclined toward the third connecting plate 308.

[0050] It also includes a third electric push rod 3011; the mounting bracket 2 is slidably connected to the fixed bracket 1; the fixed bracket 1 is bolted to the third electric push rod 3011, and the telescopic end of the third electric push rod 3011 is fixedly connected to the mounting bracket 2.

[0051] In this embodiment, water pipe 305 is connected to an external water pump, the inside of the first annular push plate 303 is connected to an external air pump, and drying pipe 307 is connected to an external air pump.

[0052] Considering that existing methods require cleaning and drying of waste plastics before grinding and pulverizing them to avoid the presence of excessive dust and impurities in the plastic powder, this invention addresses this issue. Before processing the waste plastics, an external water pump and water pipe 305, connected to the first annular pusher plate 303, deliver cleaning fluid to the cleaning chamber composed of the first connecting plate 301, the first annular pusher plate 303, and the second connecting plate 304. Subsequently, the waste plastics to be processed are manually poured into the cleaning chamber, allowing them to soak and clean in the cleaning fluid. During the cleaning process, an external air pump is controlled to repeatedly fill and deflate the first annular pusher plate 303, causing the movable part 3031 to move up and down within the cleaning chamber and the elastic part 3032 to be stretched repeatedly, pushing the plastic within the cleaning chamber and causing it to roll, thus improving the cleaning efficiency and effectiveness.

[0053] After cleaning is completed (the cleaning time is preset manually, such as 15 minutes or 20 minutes), the external water pump and water pipe 305 are first used to remove the cleaning fluid from the cleaning chamber. Then, the first electric push rod 302 is controlled to move the first annular push plate 303 upward until the upper sides of the first annular push plate 303 and the second connecting plate 304 are aligned. Next, the external air pump is started to supply air into the first annular push plate 303, making the outer side of the first annular push plate 303 higher than the inner side. This allows the cleaned waste plastic on the first annular push plate 303 to fall into the drying chamber formed by the second connecting plate 304, the third connecting plate 308, and the second annular push plate 3010 under its own gravity. During the initial cleaning, the outer side of the first annular push plate 303 is lower than the inner side to guide the cleaning fluid, facilitating the flow of the cleaning fluid in the cleaning chamber into the water pipe 305 under its own gravity. After venting, the external air pump is started, and hot air is delivered to the inside of the second connecting plate 304 through the drying pipe 307 to dry the waste plastic inside the second connecting plate 304. After drying, the second electric push rod 309 is controlled to push the second annular push plate 3010 upward. At this time, the waste plastic inside the second connecting plate 304 falls downward into the grinding bucket 103 for processing under its own gravity. Since the upper surface of the second annular push plate 3010 is inclined towards the third connecting plate 308, the waste plastic is guided downward to avoid plastic residue inside the second connecting plate 304. In this way, the present invention integrates the cleaning and drying process into the grinding bucket 103. Compared with the existing equipment with external cleaning and drying processes, it can greatly reduce the overall size of the equipment, reduce costs, and is more convenient and faster, while improving the continuous processing efficiency of waste plastic.

[0054] It should be noted that the upper side of the first connecting plate 301 is higher than the upper side of the second connecting plate 304, meaning that the cleaned waste plastic will not fall out through the first connecting plate 301; it should also be noted that the upper side of the second connecting plate 304 is higher than the upper side of the third connecting plate 308, meaning that the dried waste plastic will not fall into the cleaning chamber through the second connecting plate 304.

[0055] After grinding is completed, the third electric push rod 3011 drives the grinding bucket 103 to move down through the mounting bracket 2, so that the grinding bucket 103 is separated from the third connecting plate 308, making it easier for the plastic particles in the grinding bucket 103 to be manually removed.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
