[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Reference Figure 1-Figure 10 As shown, the present invention provides a packaging plastic hot melt recycling device, comprising:

[0047] A bottom plate 1, a mixing tank 2 is arranged on the top of the bottom plate 1, a feed slot 418 is opened on the outside of the mixing tank 2, a conveying shell 6 is fixedly connected to the right side of the mixing tank 2, and the mixing tank 2 is connected to the inside of the conveying shell 6 through the feed slot 418;

[0048] The cleaning mechanism 4 includes a cleaning component, a cleaning component and a drying component. The cleaning component is arranged on the inner side of the conveying shell 6 to screen out the impurities before the packaging plastic is hot-melted. The cleaning component is arranged on the outer side of the conveying shell 6 to clean the impurities carried on the packaging plastic. The drying component is arranged on the outer side of the mixing tank 2 to dry the cleaned packaging plastic.

[0049] The mixing mechanism 3 includes a stirring component and a drainage component. The stirring component is arranged inside the mixing tank 2 and is used for hot-melting and stirring the packaging plastic in the mixing tank 2. The drainage component is arranged inside the mixing tank 2 and is used for discharging solid particles in the packaging plastic after hot-melting.

[0050] The feeding assembly 5 is arranged outside the conveying shell 6 and is used for feeding and crushing the packaging plastic.

[0051] In a further embodiment, referring to Figure 1-Figure 3 and Figure 6The impurity removal component includes a conveyor belt 417, which is arranged inside the conveying shell 6. The conveyor belt 417 is arranged in a mesh shape. The conveyor belt 417 is fixedly connected with convex strips 416 distributed at equal intervals. The convex strips 416 are used to push the accumulated plastic to move when the conveyor belt 417 conveys the plastic. The top of the convex strips 416 is arranged in an arc shape, and one end of the sieve plate 413 can be intermittently pushed up when moving. The conveying shell 6 is provided with an inclined sieve plate 413. The bottom of the conveying shell 6 is provided with a discharge trough 405. The discharge trough 405 is used to discharge dust impurities and cleaning water in the plastic and enter the collection container below to be collected. A fixing rod 414 is movably connected to the side through a bearing, and a sieve plate 413 is fixedly connected to the outer side of the fixing rod 414. Under the action of the rotatable fixing rod 414, the side of the sieve plate 413 close to the conveyor belt 417 can be flipped, and can be intermittently shaken under the action of the convex strip 416, so as to improve the efficiency of screening out dust and debris in the plastic. A dust box 410 is arranged under the conveying shell 6, and the dust box 410 collects the dust and impurities screened out by the sieve plate 413. An L-shaped plate 415 is fixedly connected to the outer side of the conveying shell 6, and a driving motor 302 is fixedly connected to the L-shaped plate 415. The driving motor 302 provides power for the operation of the conveyor belt 417 and the crushing roller 502.

[0052] Specifically, the sieve plate 413 is disposed below the feed hopper 501 and one side thereof is placed on the conveyor belt 417. The plurality of convex strips 416 on the conveyor belt 417 intermittently push the sieve plate 413 to lift and shake when the conveyor belt 417 moves, and the vibration generated thereby screens out dust in the plastic.

[0053] In this embodiment, the driving motor 302 drives the conveyor belt 417 to operate via the output shaft. When the conveyor belt 417 is in operation, it conveys the crushed plastic, and the screen plate 413 can be shaken under the action of the conveyor belt 417 to screen out dust and debris in the plastic. By screening out debris in the plastic, the quality of the recycled plastic is improved.

[0054] In a further embodiment, referring to Figure 1-Figure 3 and Figure 5The cleaning component includes a water pump 407, which is arranged on the top of the conveying shell 6. The water pump 407 can provide a stable water supply for the nozzle 411. The water outlet of the water pump 407 is fixedly connected to the water outlet pipe 408, and the other end of the water outlet pipe 408 is provided with a nozzle 411. The water pumped by the water pump 407 enters the nozzle 411 through the water outlet pipe 408. The bottom of the nozzle 411 is provided with nozzles 412 distributed at equal intervals. The water inlet of the water pump 407 is fixedly connected to the water inlet pipe 406, and the other end of the water inlet pipe 406 extends into the drying component. When the drying component is working, the water flowing in the water inlet pipe 406 is heated to improve the cleaning effect of dust and residue on the outside of the plastic. A water collecting tank 401 is provided at the bottom of the conveying shell 6. The water collecting tank 401 is used to collect cleaning waste water, so that the cleaning water can be continuously used after treatment, thereby improving the utilization rate.

[0055] One end of the water inlet pipe 406 is arranged to penetrate the gas pipeline 402. The hot air transported by the gas pipeline 402 heats the water inside the gas pipeline 402. The water inlet pipe 406 located in the gas pipeline 402 is made of copper or other materials with good thermal conductivity.

[0056] In this embodiment, the plastic cleaned by the impurity removal component moves to the bottom of the nozzle 412 under the action of the conveyor belt 417. The nozzle 412 rinses the plastic on the conveyor belt 417, and the rinsing water is heated by the drying component, which can effectively rinse off the dust and residue on the outside of the plastic.

[0057] In a further embodiment, referring to Figure 1-Figure 3 and Figure 5 as well as Figure 7 The drying component includes an air delivery pipe 402, which is arranged on the top of the mixing tank 2. The top of the mixing tank 2 is fixedly connected with heat conduction fins 419 distributed at equal intervals. The bottom of the heat conduction fins 419 passes through the top of the mixing tank 2 and extends into the interior of the mixing tank 2, which is used for heat exchange and conduction of heat in the mixing tank 2. A blower 403 is fixedly connected to the top of the air delivery pipe. The blower 403 can transmit stable and continuous wind power to the air delivery pipe 402 to facilitate the flow of heat. The air outlet of the blower 403 is fixedly connected with an air inlet pipe 404, and the other end of the air inlet pipe 404 passes through the air delivery pipe 402 and is connected to the inside of the air delivery pipe 402.

[0058] Specifically, the gas flow rate of the blower 403 entering the gas pipeline 402 through the air inlet pipe 404 should not be too large, and can stably drive the hot air to flow into the conveying shell 6 to avoid the blowing of the plastic due to excessive wind force. The blown air passes through the conveyor belt 417 and the plastic, and is discharged from the conveying shell 6 through the discharge trough 405.

[0059] After the hot air dries the water stains on the surface of the plastic, the heat can preheat the plastic, so that the plastic entering the mixing tank 2 is heated, which is convenient for the subsequent rapid melting of the plastic under the action of the heating strip 201.

[0060] In this embodiment, the heat generated by the hot-melt plastic in the mixing tank 2 is transmitted to the gas pipeline 402 through the heat conduction fins 419, and the cleaned plastic is dried under the action of the blower 403. By drying the cleaned plastic, a large amount of water is avoided in the hot-melt plastic, which helps to improve the hot-melt speed and effect of the plastic.

[0061] In a further embodiment, referring to Figure 1-Figure 4 The feed assembly 5 includes a feed hopper 501, which is fixedly connected to the outside of the conveying shell 6. A crushing roller 502 is arranged inside the feed hopper 501. The crushing rollers 502 are symmetrically arranged. The rear ends of the two crushing rollers 502 are driven by two gears. A sprocket 503 is fixedly connected to the outside of one of the crushing rollers 502 and the outside of the output shaft of the driving motor 302.

[0062] Specifically, the two sprockets 503 are sleeved with the same chain on their outer sides, and the two sprockets 503 are connected via a chain transmission. When the driving motor 302 drives the conveyor belt 417 to work, one of the crushing rollers 502 is driven to rotate under the action of the sprocket 503 and the chain, thereby crushing the plastic. The gap between the two crushing rollers 502 is set appropriately so that the crushed plastic is in block shape, and it should not be too small.

[0063] In this embodiment, the feed hopper 501 crushes the recycled packaging plastic when it enters, so that the dust and residue on the outside of the packaging plastic can fall off during crushing, and the crushing roller 502 and the cleaning mechanism 4 are driven by the sprocket 503 and the chain, which reduces the use of the motor and improves the linkage of the various components of the device.

[0064] In a further embodiment, referring to Figure 7-Figure 10The stirring assembly includes a transmission rod 307, which is movably connected to the inner side of the mixing tank 2 through a bearing. A stirring blade 306 is fixedly connected to the upper side of the transmission rod 307. The stirring blade 306 is distributed in a ring shape on the outer side of the transmission rod 307 and is used to stir the plastic when rotating. A spiral blade 308 is arranged at the lower side of the transmission rod 307. The spiral blade 308 can stir the melted plastic at the bottom of the mixing tank 2, and can drive it to move upward while stirring, thereby improving the stirring effect. The inner side of the mixing tank 2 is provided with heating strips 201 distributed at equal intervals. The heating strips 201 are used to heat and melt the plastic entering the mixing tank 2. A bracket 304 is fixedly connected to the top of the mixing tank 2. A servo motor 409 is fixedly connected to the inner side of the bracket 304. The servo motor 409 A driving gear 303 is fixedly connected via an output shaft, a driven gear 305 is fixedly connected to the top of a transmission rod 307, an outer side of the driving gear 303 meshes with an outer side of the driven gear 305, an annularly distributed oblique rod 310 is fixedly connected to the inner side of the mixing tank 2, the oblique rod 310 is used to block and guide particles sliding down the inner wall of the mixing tank 2, and facilitate their entry into the discharge hole 309, an annularly distributed discharge hole 309 is provided on the inner side of the mixing tank 2, a drain pipe 301 is fixedly connected to the inner side of the discharge hole 309, the drain pipe 301 is used to discharge collected particulate matter, a valve 1 is provided in the middle of the drain pipe 301 for controlling the drain pipe 301, a discharge pipe 311 is provided at the bottom of the mixing tank 2, a valve 2 is provided in the middle of the discharge pipe 311 for controlling the discharge of the discharge pipe 311.

[0065] In this embodiment, the servo motor 409 drives the transmission rod 307 to rotate through the output shaft, the driving gear 303 and the driven gear 305, and stirs the plastic in the mixing tank 2 under the action of the stirring blade 306, so as to facilitate uniform heating and improve the melting efficiency. At the same time, some solid particles in the plastic melt can be removed while stirring, further improving the quality of the recycled plastic.

[0066] It should be noted that the above-mentioned drive motor 302, servo motor 409, water pump 407, blower 403 and heating strip 201 are all related to the prior art and are well known in the art, and will not be described in detail again.

[0067] The working principle of the present invention is as follows:

[0068] When hot-melt recycling of packaging plastics is performed, the recycled packaging plastics are put into the feed hopper 501. The packaging plastics entering the feed hopper 501 are crushed by the crushing roller 502. When crushing, the dust and debris on the surface and inside of the plastics are separated and dropped, and enter the bottom through the sieve plate 413 for collection;

[0069] The crushed plastic falls onto the screen plate 413, and enters the conveyor belt 417 under the action of the inclined screen plate 413. The convex strips 416 on the conveyor belt 417 can convey the plastic, and the screen plate 413 is intermittently shaken under the action of the convex strips 416 to screen out dust and debris;

[0070] The plastic processed by the sieve plate 413 enters the conveyor belt 417 for transportation. When it is transported to the bottom of the nozzle 412, the water pump 407 drives the water to enter the nozzle 412. The hot water sprayed by the nozzle 412 washes the plastic on the conveyor belt 417. The washed water carries dust and impurities and enters the water collection tank 401 below for storage.

[0071] The heat from the melted plastic in the mixing tank 2 enters the air delivery pipe 402 through the heat conduction fins 419, and the blower 403 can blow air into the air delivery pipe 402 through the air inlet pipe 404, driving the heated air into the delivery shell 6;

[0072] The washed plastic continues to move to the left along the conveyor belt 417. When the conveyor belt is under the gas pipeline 402, the hot air output from the gas pipeline 402 dries the washed plastic. The dried plastic enters the mixing tank 2 for hot melting operation.

[0073] The plastic entering the mixing tank 2 is heated and melted by the heating strip 201, and the servo motor 409 drives the transmission rod 307 to rotate through the output shaft, the driving gear 303 and the driven gear 305. The transmission rod 307 rotates and stirs the plastic in the mixing tank 2 under the action of the stirring blade 306, so as to facilitate its rapid melting.

[0074] When the stirring blade 306 continues to stir the hot-melt plastic melt, the unprocessed solid particles in the plastic melt are thrown out under the action of centrifugal force, flow downward along the inner wall of the mixing tank 2, and enter the discharge hole 309 and are discharged under the obstruction of the inclined rod 310 and the heating strip 201. The packaging plastic that has been hot-melt treated is discharged from the mixing tank 2 through the discharge pipe 311 to proceed to the next process.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
