Description

Technical Field

[0001] This invention belongs to the field of plastic processing technology, and specifically relates to a hybrid type recycled plastic processing machine. Background Technology

[0002] With the increasing consumption of plastic products, the amount of waste plastic is also increasing. Plastic recycling refers to the process of recycling waste plastics using certain recycling technologies to turn waste into treasure. The production process of plastic recycling and processing mainly includes steps such as collection and classification, cleaning, crushing, granulation, and molding. Since different types of plastics have different physical and chemical properties, mixing them together will reduce recycling efficiency and product quality. Therefore, it is necessary to classify and sort these mixed plastics during processing. With the continuous advancement of technology, traditional plastic sorting methods such as manual visual inspection and mechanical selection are gradually being phased out, while the use of advanced equipment such as hyperspectral cameras to sort and process mixed plastics is playing an increasingly important role.

[0003] In the existing technology, plastic fragments are transported to a spectral detection lens by a feeding conveyor belt for recording and identification. The signal control system controls the air valve and other devices to spray plastic according to the identification signal to achieve sorting and processing. However, the inventors discovered that during actual processing, the external ambient air is filled with dust generated during processing. This dust may adhere to the spectral detection lens and the illumination source, causing light scattering or absorption, thereby reducing the clarity and accuracy of the image. It is also necessary to frequently clean the dust on components such as the lens and the illumination system, which increases the workload and maintenance cost of the equipment. Furthermore, the light conditions and intensity in the external environment are not the same. For example, the same type of plastic may exhibit different spectral characteristics under sunlight and artificial light sources. Plastic fragments may also produce strong reflection or scattering phenomena. This change will reduce the accuracy of the spectral signal and produce errors. The mixed plastic fragments are covered with various stains and need to be cleaned and dried before sorting. Drying relies on airflow for heating, but because the plastic fragments tend to pile up and stick together after being wet, some areas may be too hot while other areas are too cold, resulting in uneven drying. Summary of the Invention

[0004] The purpose of this invention is to provide a hybrid plastic recycling processing machine that can protect the conveyor belt and spectral detection device from dust and light through a light-absorbing cover and a closed cover. At the same time, a two-way fan removes dust and filters the drawn airflow before discharge. With the rotation of the rollers, the plastic processing material is blown and dehumidified. This not only prevents dust from the external environment from entering the sorting device, but also prevents the influence of external light on the spectral detection device. It can also further turn over and air dry the plastic processing material that is not completely dried, thereby improving the detection quality.

[0005] The specific technical solution adopted by this invention is as follows: A hybrid type recycled plastic processing machine includes a fixed frame fixedly assembled on one side of a sorting device. A spectral detection device is fixedly assembled inside the sorting device. A partition is provided on the top of the fixed frame adjacent to the sorting device. A light-absorbing cover is mounted on one side of the fixed frame and driven by the partition. Several rollers for turning materials are rotatably arranged at equal distances inside the fixed frame and on one side of the light-absorbing cover. The outer wall of the rollers is provided with spiral perforations in an array. A spiral guide plate for guiding materials is fixedly connected to the inner wall of the rollers. A meshing transmission mechanism for driving the rollers to rotate is provided at one end of the rollers. The roller is symmetrically connected to a connecting pipe seat above it. A bidirectional ventilator is fixedly assembled on the top of each connecting pipe seat, and the ventilator extends the suction airflow to the area below the spectral detection device to adsorb dust through the ventilation components. The light-absorbing cover can prevent external dust and light from entering the sorting device, and is used to shield the spectral detection device and the plastic processing material from light and dust.

A first sliding groove is provided on one side of the top of the light-absorbing cover for the sliding wheel to slide.

[0009] The top two ends of the partition are symmetrically fixed with spring coiling devices. A shielding strip is spring-connected between the two spring coiling devices and inside the sliding groove. The outer wall of the sliding rod is fixedly connected to the shielding strip. A fixing plate is fixedly connected to one side of the partition. A magnetic suction plate for adsorbing the sliding rod is fixedly assembled at one end of the fixing plate.

[0010] The top of the light-absorbing cover is provided with an observation window, and a folding plate is movably arranged above the observation window. The top of the light-absorbing cover is equipped with a threaded transmission mechanism for simultaneously controlling the folding of the folding plate. The threaded transmission mechanism includes a sliding block, a fixed platform is fixedly assembled on the top of the light-absorbing cover and at both ends of the folded plate, one end of the folded plate is fixedly connected to one of the fixed platforms, a screw is rotatably connected between the two fixed platforms, a limit rod is fixedly assembled below the screw, the sliding block is threaded onto the outer wall of the screw, and the middle part of the sliding block is slidably connected to the limit rod.

[0011] The meshing transmission mechanism includes extension rings fixedly assembled at both ends of the roller. The outer walls of each extension ring are rotatably assembled with fixed rings. The closed cover is fixedly connected to the fixed rings. The outer walls of each extension ring located at one end of the roller are fixedly connected with gear 1. Every two gear 1 are meshed with each other. A motor is fixedly assembled at one end of the interior of the fixed frame. The output end of the motor is fixedly connected with gear 2. Gear 2 meshes with any gear 1.

[0012] Inside the fixed frame and below the light-absorbing cover, a conveyor belt is installed. At the bottom of one end of the roller and above the conveyor belt, a feed plate is provided. One side of the feed plate is fixedly connected with protruding rods in an array. Support rods are symmetrically fixedly connected to both sides of the inner wall of the fixed frame.

[0015] The technical effects achieved by this invention are as follows: This invention uses a light-absorbing cover and a sealing cover to cover the outside of the conveyor belt, while simultaneously protecting the conveyor belt and the spectral detection device from dust and light. At the same time, a two-way ventilation fan removes dust from the surface of the spectral detection device and filters the drawn airflow before discharging it. With the rotation of the rollers, the plastic processing material is blown and dehumidified. By covering the outside of the conveyor belt with a light-absorbing cover, and by installing internal air ducts and air nozzles, external dust can be prevented from entering the sorting device during inspection and processing. This prevents dust from adhering to the spectral detection device and the processed materials, thereby maintaining the clarity and accuracy of the image signal from the spectral detection device, reducing the frequency of maintenance and cleaning, and reducing workload. By using a light-absorbing cover placed above the conveyor belt and the adaptive sliding of the folding curtain, the external ambient light can be prevented from directly illuminating the spectral detection device and the processed materials during inspection and processing. This avoids reflection and scattering of the processed materials, reduces the influence and interference of external light on the spectral detection device, and thus improves the accuracy of the spectral signal. By using a two-way fan to blow air through the spiral perforations into the drum, the processed materials that were missed during the drying process and were not completely dried are further turned over and dried, removing moisture from the surface of the processed materials, avoiding light scattering caused by moisture, and improving the quality of testing.

[0018] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0019] like Figures 1-4 As shown, a hybrid type recycled plastic processing machine includes a fixed frame 101 fixedly assembled on one side of a sorting device 1. A spectral detection device 110 is fixedly assembled inside the sorting device 1. A partition 207 is provided on the top of the fixed frame 101 adjacent to the sorting device 1. A light-absorbing cover 2 is mounted on one side of the fixed frame 101 and driven by it. A conveyor belt 109 is mounted inside the fixed frame 101 and below the light-absorbing cover 2. A closed cover 102 is fixedly assembled above the roller 3, and a connecting pipe seat 103 is fixedly connected to the top of the closed cover 102. Example 1: See attached document Figure 1 , Figures 4-8 , Figure 13Inside the fixed frame 101, and equidistantly rotatably arranged on one side of the light-absorbing cover 2, are several rollers 3 for turning materials. A feed hopper 105 is fixedly assembled at the top of the closed cover 102 and at one end of the rollers 3. The outer walls of the rollers 3 are perforated with spiral holes 301 arranged in an array. A spiral guide plate 318 for guiding materials is fixedly connected to the inner wall of the rollers 3. One end of the rollers 3 is provided with a meshing transmission mechanism for driving its own rotation. The meshing transmission mechanism includes extension rings 302 fixedly assembled at both ends of the rollers 3. Fixed rings 303 are rotatably assembled on the outer walls of the extension rings 302. The closed cover 102 is fixedly connected to the fixed rings 303. Gear 1 304 is fixedly connected to the outer wall of the extension rings 302 located at one end of the rollers 3. Every two gear 1 304 mesh with each other. A motor 305 is fixedly assembled at one end inside the fixed frame 101. A gear 2 306 is fixedly connected to the output end of the motor 305. Wheel 2 306 meshes with any gear 1 304. A feed plate 308 is provided at the bottom of one end of the roller 3 and above the conveyor belt 109. A protruding rod 309 is fixedly connected in an array on one side of the feed plate 308. Support rods 2 316 are symmetrically fixedly connected on both sides of the inner wall of the fixing frame 101. The feed plate 308 is slidably connected to the support rods 2 316 through the sliding block 2 317 at the bottom. A vertical plate 314 is fixedly connected to the bottom of the feed plate 308. A through groove 315 is opened through the middle of the vertical plate 314. A connecting shaft 310 is fixedly connected to one side of the gear 2 306 and below the roller 3. A rotating wheel 312 is fixedly connected to one end of the connecting shaft 310. A locking rod 313 for movably embedding into the through groove 315 is fixedly connected to one side of the rotating wheel 312. A cover plate 311 is symmetrically rotated and assembled on the top of the connecting shaft 310. The cover plate 311 is fixedly connected to the fixing frame 101 through the fixing rod 307 on the outer wall.

[0020] According to the above structure, the plastic processing material is fed into the interior of one end of the roller 3 through the feed hopper 105. The electric control motor 305 drives the second gear 306 to rotate, and the second gear 306 drives the first gear 304 to rotate. When one gear 304 rotates, it can drive the other gears 304 to rotate together. The first gear 304 drives the extension ring 302 and the roller 3 to rotate. The fixed ring 303 provides support at both ends of the roller 3. When the roller 3 rotates, it causes the processing material inside to be lifted and turned over. The spiral perforation 301 is used for the injection of subsequent external airflow and the dissipation of moisture. The spiral direction of the spiral perforation 301 can make the external airflow gain a rotational component when it passes through, and affect the airflow direction and flow rate, increasing the contact area between the airflow and the material inside the roller 3. When the material is turned over, it is blown and dehumidified. The spiral direction of the spiral guide plate 318 can guide the material to move forward in the direction of the conveyor belt 109 when rotating. After the material is turned over and splashed with water by the roller 3, the spiral guide plate 318 guides it to the conveyor belt 109. The material is discharged onto the feed plate 308. When the motor 305 drives the gear 306 to rotate, the connecting shaft 310 also rotates. The connecting shaft 310 drives the turntable 222, the wheel 312, and the insert rod 313 to rotate. Since the insert rod 313 is always engaged with the through groove 315, and the feed plate 308 is restricted to moving only left and right by the support rod 316, the insert rod 313 drives the vertical plate 314 to move linearly through the annular sliding within the through groove 315, thereby causing the feed plate 308 to reciprocate, and the material falls onto the feed plate 308. When the material is released, the feeding plate 308 disperses the material, and the small contact area of ​​the protruding rod 309 results in a short collision time with the material, making it easier to bounce the material up and make it fall more evenly onto the conveyor belt 109. The fixing rod 307 supports the connecting shaft 310, and the cover plate 311 prevents water splashed out by the roller 3 from falling onto the connecting shaft 310. It should be noted that, in order to fully display the structure under the roller 3, the bottom protective cover of the fixing frame 101 is temporarily hidden, therefore, attached Figure 7 The bottom of the central fixing bracket 101 is hollow, which should not be considered as affecting the sealing performance of the fixing bracket 101.

[0021] The working principle of this invention is as follows: the motor 305 controls the drum 3 to further turn and air dry the materials that were missed or not completely dried during the pre-drying process, remove the moisture from the surface of the materials, improve the detection quality, and can also synchronously control the reciprocating movement of the vertical plate 314 and the feed plate 308, so that when the materials fall onto the feed plate 308, they are shaken and bounced up, so that the materials are more evenly distributed on the conveyor belt 109.

[0022] Example 2: See attached document Figure 1 , Figure 4 , Figure 6 , Figures 9-12A connecting pipe seat 103 is symmetrically arranged above the roller 3. A bidirectional ventilator 104 is fixedly assembled on the top of each connecting pipe seat 103. The ventilator extends the suction airflow to below the spectral detection device 110 to adsorb dust via a ventilation assembly. The ventilation assembly includes an outer duct 106 fixedly mounted on the top of the bidirectional ventilator 104. An outer duct 107 is symmetrically fixedly assembled on both sides of the mounting frame 101. One end of the outer duct 106 is connected to the outer duct 107. An inner duct 111 is symmetrically fixedly assembled inside the sorting device 1 on both sides of the spectral detection device 110. An inner duct 112 is fixedly connected to the bottom of each inner duct 111. One end of the inner duct 112 is inclinedly positioned on both sides of the bottom of the spectral detection device 110. One end of the inner duct 111 is connected to the outer duct 107. The outer wall of the mounting frame 101 and... A filter box 108 is fixedly assembled in the middle of the outer air duct 107. An inner air duct 113 is arranged and assembled inside the partition 207 and the enclosure 102 and along the edge of the light-absorbing cover 2. Air nozzles 114 are fixedly assembled at equal intervals on the outer wall of the inner air duct 113. One end of the inner air duct 113 is connected to the outer air duct 107. An air valve 115 is fixedly assembled at one end of the inner air duct 113 and inside the sorting device 1. A rod 211 is movably inserted into one side of the sorting device 1 and outside the light-absorbing cover 2. The rod 211 is movably inserted into the air valve 115 through a branch rod 226 at one end. A clamping block 210 for sliding engagement of the rod 211 is fixedly connected to one side of the light-absorbing cover 2. Support rods 212 are symmetrically fixedly connected to the outer wall of the rod 211 and on both sides of the clamping block 210. A notch is opened on one side of the clamping block 210 for the support rod 212 to slide through.

[0023] According to the above structure, when the bidirectional ventilator 104 is started, its impeller rotates to generate centrifugal force, drawing air from the inner duct 112. The opening of the inner duct 112 is tilted towards the bottom of the spectral detection device 110, so as not to affect the spectral detection work of the spectral detection device 110, and can also suck away the dust on its outer wall. The sucked air enters the outer duct 107 along the inner duct 111. When passing through the filter box 108 in the middle of the outer duct 107, the air is filtered for dust. Then the airflow enters the outer duct 106, and after being accelerated by the impeller inside the bidirectional ventilator 104, it is discharged into the connecting pipe seat 103. After passing through the connecting pipe seat 103, it is directly blown onto the drum 3. When the drum 3 tumbles the material, the material is blown in through the spiral perforation 301. The light-absorbing hood 2 can be hydraulic, pneumatic, electric, etc. The existing transmission method is used for opening and closing. When it is necessary to open the light-absorbing cover 2 to inspect, examine, and maintain the internal components, the insertion rod 211 is rotated by the support rod 212 so that the support rod 212 is aligned with the notch on one side of the clamping block 210 for easy sliding removal. When the insertion rod 211 rotates, it will drive the air valve 115 to rotate through the branch rod 226 at one end. When the air valve 115 rotates and opens, the inner air duct 113 and the partition 207 are unobstructed. The suction airflow from the bidirectional fan 104 is divided into the inner air duct 113. The inner air duct 113 is ventilated through the air nozzle 114. The inner air duct 113 is laid along the opening shape of the light-absorbing cover 2 to form a suction area to prevent external dust from entering the partition 207 and the sorting device 1 after the light-absorbing cover 2 is opened.

[0024] The working principle of this invention is as follows: by controlling the arrangement of the bidirectional ventilation fan 104 and the outer air duct 107, inner air duct 111 and inner air duct 113, the outer wall of the spectral detection device 110 can be vacuumed, and the open opening can be sucked to prevent dust when the light absorption cover 2 is opened. The sucked air is finally filtered by the filter box 108 and delivered to the connecting pipe seat 103 for blowing and drying the material in the roller 3.

[0025] Example 3: See attached document Figures 1-3 , Figures 10-11The top of the partition 207 has a through-hole sliding groove 208. Spring coiling devices 213 are symmetrically fixed at both ends of the top of the partition 207. A cover strip 223 is spring-connected between the two spring coiling devices 213 and inside the sliding groove 208. The outer wall of the sliding rod 215 is fixedly connected to the cover strip 223. A folding curtain 225 is provided between the two plates of the partition 207, and a manual opening and closing mechanism for driving the folding curtain 225 is correspondingly configured. The manual opening and closing mechanism includes the through-hole sliding groove 208 at the top of the partition 207, with the sliding rod 215 slidably connected to the inner wall of the sliding groove 208. A support rod 224 is fixedly connected to the inner wall and below the sliding groove 208. The folding curtain 225 is slidably sleeved on the outer wall of the support rod 224. One end of the folding curtain 225 is fixedly connected to the partition 207. One end of the sliding rod 215 is fixedly connected to one end of the folding curtain 225. A sliding wheel 216 is fixedly connected to the outer wall of one end of the sliding rod 215 at an incline. A sliding groove 206 is provided on one side of the top of the light-absorbing cover 2 for the sliding wheel 216 to slide. A fixing plate 209 is fixedly connected to one side of the partition 207. A magnetic suction plate 214 for adsorbing the sliding rod 215 is fixedly assembled at one end of the fixing plate 209.

[0026] According to the above structure, when the light-absorbing cover 2 is opened, one end of it is a rotating shaft, and the other end is raised upwards. When the light-absorbing cover 2 is raised, it squeezes the sliding wheel 216 through the sliding groove 206, causing it to move. The movement of the sliding wheel 216 drives the magnetic suction plate 214 to move. As one end of the light-absorbing cover 2 is continuously raised, the sliding rod 215 also continuously moves towards one end of the partition 207. When the partition 207 moves, it drives the folding curtain 225 to unfold along the support rod 224, thereby opening on one side of the spectral detection device 110. To prevent external light from affecting the spectral detection device 110 when the light-absorbing cover 2 is open, the shielding strip 223 moves together with the sliding rod 215, and the coiling spring device 213 also rolls up and down the shielding strip 223 accordingly. The shielding strip 223 can always keep the sliding groove 208 closed, preventing dust and light. When the light-absorbing cover 2 is closed, the sliding wheel 216 is pulled down by the sliding groove 206 and begins to move towards the fixing plate 209, and is finally attracted and fixed by the magnetic plate 214.

[0027] See attached document Figures 1-4 , Figure 11The light-absorbing cover 2 has an observation window 201 on its top. A folding plate 202 is movably arranged above the observation window 201. A threaded transmission mechanism for simultaneously controlling the folding of the folding plate 202 and the movement of the sliding rod 215 is assembled on the top of the light-absorbing cover 2. The threaded transmission mechanism includes a sliding block 217. Fixed platforms 203 are fixedly assembled on the top of the light-absorbing cover 2 at both ends of the folding plate 202. One end of the folding plate 202 is fixedly connected to one of the fixed platforms 203. A screw 204 is rotatably connected between the two fixed platforms 203. A limit rod 205 is fixedly assembled below the screw 204. One end of the screw 204 is located at the fixed platform 205. A turntable 222 is fixedly connected to one side of the platform 203. A sliding block 217 is threaded onto the outer wall of the screw 204. The middle part of the sliding block 217 is slidably connected to the limiting rod 205. One end of the sliding block 217 is fixedly connected to one end of the folding plate 202. A sliding groove 218 is provided through one end of the sliding block 217. A baffle 219 is symmetrically damped and slidably connected to the inner wall of the sliding groove 218. A crossbar 220 is slidably connected to the top of the sliding block 217. One end of the crossbar 220 is fixedly connected to the baffle 219. The other end of the crossbar 220 is fixedly connected to a hook rod 221 for hooking and fixing the platform 203.

[0028] According to the above structure, the interior of the light-absorbing cover 2 can also be observed through the observation window 201. The folding of the folding plate 202 can make the observation window 201 appear or disappear. In order to prevent external light from passing through the observation window 201 and entering the partition 207 and the detection port below the spectral detection device 110 during observation, the folding curtain 225 must be able to move synchronously with the sliding block 217, and a forced prompting for this operation should be made every time the folding plate 202 is folded. The following are the operation steps: In the initial state, in order to ensure that the baffle 219 does not affect the movement of the sliding rod 215 when the light-absorbing cover 2 is open, the baffle 219 is normally located outside the end of the sliding rod 215. However, when observation is required through the observation window 201... At this time, since the hook 221 is hooked onto the fixed platform 203, rotating the turntable 222 cannot make the screw 204 rotate. Only by pushing the crossbar 220, the crossbar 220 drives the two baffles 219 to move to both sides of the sliding rod 215. The hook 221 also moves away from the fixed platform 203. At this time, rotating the turntable 222 drives the screw 204 to rotate. At the same time, under the restriction of the limit rod 205, the sliding block 217 moves radially along the screw 204. The sliding block 217 drives the baffle 219 to move together. The baffle 219 can then push the sliding rod 215 to move together, thereby causing the folding curtain 225 inside the partition 207 to move accordingly. The sliding block 217 simultaneously drives one end of the folding plate 202 to start folding, revealing the observation window 201.

[0029] The working principle of the present invention is as follows: by covering the top of the fixed frame 101 with the light-absorbing cover 2 and the sealing cover 102, external dust and light can be prevented from entering the sorting device 1 and the conveyor belt 109. When the light-absorbing cover 2 and the folding plate 202 are opened and closed respectively, the folding curtain 225 can be controlled to move and block the light on one side of the spectral detection device 110.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
