[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-10 One embodiment of the present invention is: an energy-saving and environmentally friendly plastic processing equipment, comprising: a base 1, a heating device 2 provided on the base 1, a reaction vessel 3 fixedly installed on the top of the base 1, a feed box 4 fixedly installed on the top of the reaction vessel 3, a feed inlet 5 provided on the left side of the feed box 4, and a stirring device provided inside the reaction vessel 3. The stirring device includes a rotating shaft 6, a spiral plate 7, a fixed outer shell 8, a sliding strip 9, a top plate 10, a circular plate 11, a long rod 12, and a scraper 13. The rotating shaft 6 is rotatably installed inside the reactor 3. The spiral plate 7 is fixedly installed on the circumferential surface of the rotating shaft 6. The fixed outer shell 8 is fixedly installed on the inner wall of the reactor 3. The sliding strip 9 is slidably installed inside the fixed outer shell 8. The top plate 10 is fixedly installed on the top of the fixed outer shell 8. The circular plate 11 is fixedly installed on the top of the rotating shaft 6. The long rod 12 is fixedly installed on the circumferential surface of the rotating shaft 6. The scraper 13 is fixedly installed at the end of the long rod 12 away from the rotating shaft 6. The rotation of the spiral plate 7 causes the molten plastic at the bottom of the reactor 3 to rise and enter the fixed outer shell 8, and then flow out from the top of the top plate 10. This ensures more uniform mixing and stirring during the plastic melting process, thereby avoiding local overheating, improving the uniformity of heating and stirring, preventing the plastic from overheating in certain areas and causing scorching or degradation, reducing the risk of plastic overheating, extending the service life of the plastic and ensuring product quality. At the same time, it can reduce unnecessary time waste during the heating process and accelerate the production cycle.

[0023] The scraper 13 contacts the inner wall of the reactor 3. A groove is provided on the fixed outer shell 8. The slide bar 9 is slidably installed in the groove provided on the fixed outer shell 8. The long rod 12 contacts the groove provided on the fixed outer shell 8. The contact ensures that the scraper 13 can clean the inner wall of the reactor 3 when it rotates. The groove ensures that the slide bar 9 can slide normally. The contact ensures that the slide bar 9 can move along the extension direction of the groove. The contact ensures that the long rod 12 can rotate normally.

[0024] In this embodiment, the following steps are required before the plastic melting process begins: First, a professional inspector checks the entire plastic processing equipment. After confirmation, the operator places the plastic to be melted into the feed box 4 through the feed inlet 5. Once inside the feed box 4, the heating device 2 is activated, raising the temperature inside the reactor 3. The plastic then enters the reactor 3 from the feed box 4 and gradually melts at the high temperature. After complete melting, the operator opens the outlet at the bottom of the reactor 3 to discharge the molten plastic for further processing. After the plastic enters the reactor 3, the motor is activated, driving the rotating shaft 6 to rotate. The rotating shaft 6 drives the spiral plate 7 to rotate, causing the molten plastic at the bottom of the reactor 3 to rise into the fixed outer shell 8 and then flow out from the top of the top plate 10. This ensures a more uniform mixing and stirring process during the plastic melting process. Stirring prevents localized overheating, improves the uniformity of heating and stirring, prevents the plastic from overheating in certain areas and causing scorching or degradation, reduces the risk of overheating, extends the service life of the plastic, and ensures product quality. It also reduces unnecessary time wastage during the heating process, accelerating the production cycle. As the rotating shaft 6 drives the spiral plate 7 to rotate, it simultaneously drives the long rod 12 to rotate. The long rod 12 rotates and contacts and pushes the slide bar 9 to move inside the fixed outer shell 8. At the same time, the rotation of the long rod 12 drives the scraper 13 to rotate. The scraper 13 scrapes off any molten plastic that may adhere to the inner wall of the reactor 3, preventing plastic accumulation inside the equipment and avoiding excessive accumulation that could affect normal operation. This ensures the cleanliness of the inner wall of the reactor 3, avoids the impact of molten material on heating efficiency, maintains efficient equipment operation, and effectively removes these adhering substances, preventing overheating and thermal degradation, thus ensuring the stability and quality of the plastic during processing.

[0025] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, a feeding control device is provided inside the feeding box 4, and a ventilation device is provided on the right side of the feeding box 4.

[0026] The feeding control device includes a rotating rod 141, a rotating block 142, a turntable 143, a fixed column 144, a transmission belt 145, a sliding ring 146, a fixed rod 147, and a baffle 148. The rotating rod 141 is fixedly installed on the top of the circular plate 11. The rotating block 142 is rotatably installed on the top of the inner wall of the feeding box 4. The turntable 143 is fixedly installed on the bottom of the rotating block 142. The fixed column 144 is fixedly installed on the bottom of the turntable 143. The rotating rod 141 and the rotating block 142 are connected by the transmission belt 145. The baffle 148 is slidably installed inside the feeding box 4. The fixed rod 147... Fixedly installed on the top of the baffle 148, the sliding ring 146 is fixedly installed on the top of the fixed rod 147. The baffle 148 reciprocates to open the channel to help the plastic material enter the heating zone or melting zone more evenly, avoid the material from gathering in a certain part, ensure that the melting degree of each part of the plastic is consistent, effectively control the speed at which the material enters the melting zone, avoid feeding too much material at one time, which would cause the temperature to be too high during the melting process, resulting in overheating or thermal degradation of the plastic. At the same time, it avoids the material from accumulating or getting stuck at the feeding box 4, ensuring that the material can continuously and stably enter the processing area.

[0027] The feeding control device also includes two rotating columns 149, a second transmission belt 1410, a pusher plate 1411, and a connecting block 1412. The two rotating columns 149 are rotatably installed on the right side of the feeding box 4 and are connected by the second transmission belt 1410. The pusher plate 1411 is fixedly installed on the left side of the second transmission belt 1410. One end of the connecting block 1412 is fixedly installed on the top of the baffle 148, and the other end of the connecting block 1412 is fixedly installed on the left side of the second transmission belt 1410. The pusher plate 1411 moves to push the plastic on the baffle 148 into the interior of the reactor 3, ensuring that the material enters the heating zone continuously and evenly. This helps to control the stability of the heating process, reduce unnecessary interruptions, and avoid uneven or unstable feeding of materials. At the same time, it can effectively avoid such accumulation and blockage, ensuring that the material enters the heating zone smoothly and avoiding production interruptions or equipment damage caused by material jamming.

[0028] The sliding ring 146 contacts the fixed post 144, and the push plate 1411 contacts the baffle 148. The contact ensures that the fixed post 144 can drive the sliding ring 146 to move when it rotates, and the contact ensures that the push plate 1411 can fully push the plastic on the baffle 148.

[0029] The ventilation device includes a movable plate 151, a connecting rod 152, a ventilation box 153, a fan 154, and a filter plate 155. The movable plate 151 is slidably installed on the inner wall of the feed box 4. One end of the connecting rod 152 is fixedly installed on the left side of the movable plate 151, and the other end of the connecting rod 152 is fixedly installed on the circumferential surface of the fixed rod 147. The ventilation box 153 is fixedly installed on the right side of the feed box 4. The fan 154 is located inside the ventilation box 153. The filter plate 155 is slidably installed inside the ventilation box 153. The fixed plate 156 is fixedly installed on the side of the filter plate 155 away from the ventilation box 153. The elastic telescopic rod 157 is fixedly installed. On the upper and lower sides of the fixed plate 156, the locking block 158 is fixedly installed at the movable end of the elastic telescopic rod 157, the limiting block 159 is fixedly installed on the right side of the feed box 4, and the pull plate 1510 is fixedly installed on the right side of the locking block 158. When toxic gases and other waste gases enter the ventilation box 153, they come into full contact with the filter plate 155. The filter plate 155 absorbs and filters most of the toxic gases and other waste gases, preventing these harmful substances from being directly emitted into the environment, reducing air pollution, lowering the concentration of toxic gases in the air inside the factory, thereby reducing the risk of workers inhaling harmful gases and helping to protect the health of workers.

[0030] The ventilation device also includes a fixed plate 156, an elastic telescopic rod 157, a locking block 158, a limiting block 159, and a pull plate 1510. The fixed plate 156 is fixedly installed on the side of the filter plate 155 away from the ventilation box 153. The elastic telescopic rod 157 is fixedly installed on the upper and lower sides of the fixed plate 156. The locking block 158 is fixedly installed on the movable end of the elastic telescopic rod 157. The limiting block 159 is fixedly installed on the right side of the feed box 4. The pull plate 1510 is fixedly installed on the right side of the locking block 158. By replacing the filter plate 155 with a brand new one, it is ensured that the filter plate 155 can properly adsorb and filter harmful gases in the next operation, and the filter plate 155 is prevented from losing its adsorption and filtration effect due to overuse.

[0031] The locking block 158 contacts the limiting block 159. The side of the locking block 158 that contacts the limiting block 159 is set as an inclined surface. The contact ensures that the limiting block 159 can restrict the locking block 158, and the inclined surface ensures that the locking block 158 can be pushed smoothly when moving.

[0032] In this embodiment, during operation: the rotating shaft 6 drives the spiral plate 7 to rotate, simultaneously causing the circular plate 11 to rotate. The circular plate 11 rotates, causing the rotating rod 141 to rotate. The rotating rod 141 rotates, causing the transmission belt 145 to rotate. The transmission belt 145 rotates, causing the rotating block 142 to rotate. The rotating block 142 rotates, causing the turntable 143 to rotate. The turntable 143 rotates, causing the fixed column 144 to rotate. The fixed column 144 rotates, causing the sliding ring 146 to move. The sliding ring 146 moves, causing the fixed rod 147 to move. The fixed rod 147 moves, causing the baffle 148 to move. The baffle 148 moves, opening the channel between the feed box 4 and the reactor 3. As the fixed column 144 rotates, causing the sliding ring 146 to move back and forth, the baffle 148 repeatedly opens the channel to help the plastic material enter the heating zone or melting zone more evenly, avoiding material accumulation in a certain part, ensuring that the melting degree of each part of the plastic is consistent, and effectively controlling the material flow. The speed at which material enters the melting zone is controlled to avoid excessive feeding at once, which could lead to overheating or thermal degradation of the plastic during the melting process. Simultaneously, it prevents material accumulation or blockage at the feed box 4, ensuring a continuous and stable flow of material into the processing area. As the baffle 148 moves to open the channel between the feed box 4 and the reactor 3, it simultaneously moves the connecting block 1412. The movement of the connecting block 1412 causes the transmission belt 1410 to rotate around the rotating column 149. The rotation of the transmission belt 1410 then moves the push plate 1411, which pushes the plastic on the baffle 148 into the reactor 3. This ensures continuous and uniform material entry into the heating zone, helping to control the stability of the heating process, reducing unnecessary interruptions, and preventing uneven or unstable feeding. It also effectively prevents accumulation and blockage, ensuring smooth material entry into the heating zone and avoiding production interruptions or equipment damage caused by material blockage.

[0033] As the fixed rod 147 moves, it drives the baffle 148 to move, simultaneously causing the connecting rod 152 to move. The moving rod 152 then drives the moving plate 151 to move, opening the channel between the ventilation box 153 and the feed box 4. At this time, the fan 154 starts blowing air outwards. Because the fan 154 blows air outwards, a negative pressure state is created inside the feed box 4. Under this negative pressure state, the toxic gases and other waste gases generated by heating and melting the plastic are discharged outwards through the ventilation box 153. When the toxic gases and other waste gases enter the ventilation box 153, they come into full contact with the filter plate 155. The filter plate 155 absorbs and filters most of the toxic gases and other waste gases, preventing these harmful substances from being directly emitted into the environment and reducing emissions. To reduce air pollution and lower the concentration of toxic gases in the factory's interior air, thereby reducing the risk of workers inhaling harmful gases and helping to protect their health, when the filter plate 155 needs to be replaced after work, the worker pulls the pull plate 1510, causing the pull plate 1510 to move the locking block 158. The locking block 158 moves and disengages from the limiting block 159, and then the limiting block 159 releases its restriction on the filter plate 155. At this time, the worker pulls the handle of the filter plate 155 to pull out the filter plate 155 to replace it with a brand new filter plate 155. This ensures that the filter plate 155 can properly adsorb and filter harmful gases in the next work, and avoids the filter plate 155 losing its adsorption and filtration effect due to overuse.
