Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, and particularly to a cleaning device for PET plastic bottle fragments. Background Art

[0002] Nowadays, due to its light weight and low price, plastic bottles are used in various industries. Most plastic bottles are disposable products. Since plastic itself cannot be naturally degraded, it has become a major pollutant of the environment. Therefore, the recycling and reuse of plastic bottles are very important. Plastic bottles include bottle bodies and bottle caps. Since the plastic components of the bottle body and the bottle cap are different, unified recycling and processing will cause pollution between the two plastics, which is not conducive to people's health.

[0003] Although the prior art can perform cleaning operations on plastic bottle fragments, the broken bottle cap plastic bottle fragments and the bottle body PET plastic fragments are mixed together, which makes it inconvenient to separate and collect the bottle cap plastic bottle fragments and the bottle body PET plastic fragments after cleaning the plastic bottle fragments. Summary of the Invention

[0009] Preferably, the extending mechanism further includes a second guiding groove formed inside the support frame. The second sliding plate is slidably connected to the second guiding groove.

[0010] Preferably, the bottle cap fragment cleaning mechanism includes a second motor arranged above the drive box. The output end of the second motor is fixedly connected to a first pulley. The first pulley is connected to a second pulley through a first transmission belt. The inner side of the second pulley is fixedly connected to a stirring shaft. A plurality of stirring blades are fixedly connected to the outer wall of the stirring shaft.

[0011] Preferably, the bottle cap fragment cleaning mechanism further includes a limiting plate fixedly connected to the drive box. A plurality of first partition plates are fixedly connected to the bottom of the limiting plate. There are a plurality of stirring shafts. Adjacent stirring shafts are connected to each other through a third pulley and a second transmission belt.

[0012] Preferably, one side of the limiting plate is fixedly connected to a first support plate. The stirring shaft is rotatably connected to the first support plate.

[0013] Preferably, the bottle body fragment cleaning mechanism includes a second partition plate fixedly connected to the bottom of the partition leakage plate. A second support plate is fixedly connected inside the cleaning tank. A spring is connected inside the cleaning tank. One end of the spring away from the cleaning tank is connected to a shaking plate. A protective shell is arranged inside the sealing plate. A third cylinder is fixedly installed inside the protective shell. The output end of the third cylinder is fixedly connected to an impact plate. The bottle body fragment cleaning mechanism further includes a third pipeline communicated with the cleaning tank. A second control valve is arranged on the third pipeline. A retaining net is arranged inside the third pipeline.

[0014] Preferably, the bottle body fragment cleaning mechanism further includes a plurality of separation plates fixedly connected to the top of the shaking plate. The plurality of separation plates are distributed in a rectangular shape.

[0015] Beneficial effects: In the present invention, the plastic bottle fragments are first conveyed into the interior of the cleaning tank through the opening at the top of the cleaning tank. Then, an external water supply pipe is connected to one end of the first pipe. After opening the first control valve, the external liquid will be conveyed into the interior of the water tank through the first pipe. Since the water tank is connected to a second pipe and a solenoid valve is provided on the second pipe, after opening the solenoid valve, the liquid will be sprayed from the water tank into the interior of the cleaning tank through the second pipe. When the interior of the cleaning tank is filled with the liquid, the plastic bottle cap fragments will float on the water surface, and the PET plastic fragments of the bottle body will sink to the bottom of the cleaning tank, separating the plastic bottle cap fragments from the PET plastic fragments of the bottle body and realizing the sorting and cleaning function of the plastic bottle fragments.

[0016] When the liquid and plastic fragments enter the interior of the cleaning tank in the present invention, the first cylinder is started. The output end of the first cylinder will drive the connecting plate to move reciprocally. Since the connecting plate is fixedly connected to the bottom of the cleaning tank, the cleaning tank will be driven to move reciprocally. In addition, the first sliding plate fixedly connected to the bottom of the cleaning tank will slide in the first guiding groove opened on the top of the base, thereby improving the stability of the cleaning tank during movement. While shaking the cleaning tank, the present invention will drive the plastic fragments inside the cleaning tank to disperse in the liquid, enabling the plastic fragments to be evenly distributed inside the cleaning tank and realizing the function of uniform feeding.

[0017] When the plastic bottle cap fragments float on the water surface and the PET plastic fragments of the bottle body sink to the bottom of the cleaning tank in the present invention, the second cylinder fixedly installed on the L-shaped bracket is started. The output end of the second cylinder will drive the partition leakage plate into the interior of the cleaning tank. The partition leakage plate has a separating effect on the plastic bottle cap fragments and the PET plastic fragments of the bottle body. The plastic bottle cap fragments will be cleaned above the partition leakage plate, and the PET plastic fragments of the bottle body will be cleaned below the partition leakage plate, improving the cleaning effect on the plastic bottle fragments.

[0018] When the separating leakage plate enters the cleaning tank and separates the plastic bottle caps from the PET plastic fragments of the bottle body, the first motor is started. The output end of the first motor drives the worm to rotate. Since a worm gear is meshed on the outer side of the worm, the worm gear and the transmission lead screw fixedly connected to the inner side of the worm gear are driven to rotate. Under the action of the lead screw nut and the second guide groove, the second sliding plate is driven to move downward. Since one end of the second sliding plate is fixedly connected with a drive box and the plastic bottle cap cleaning mechanism is arranged on the drive box, the plastic bottle cap cleaning mechanism can be driven to extend into the cleaning tank and be located above the plastic bottle caps. When the plastic bottle cap cleaning mechanism of the present invention moves above the plastic bottle caps, the limiting plate on the plastic bottle cap cleaning mechanism has a limiting effect on the top of the plastic bottle caps, and the separating leakage plate has a limiting effect on the bottom of the plastic bottle caps, so that the plastic bottle caps are limited between the limiting plate and the separating leakage plate. In addition, a plurality of first separating plates fixedly connected to the bottom of the limiting plate divide the limiting space into a plurality of small spaces. At this time, the second motor is started, and the output end of the second motor drives the first pulley to rotate. Since the first pulley is connected to the second pulley through the first transmission belt, the second pulley and the stirring shaft inside the second pulley are driven to rotate. There are a plurality of stirring shafts, and the plurality of stirring shafts are connected through the third pulley and the second transmission belt, so that the plurality of stirring shafts can drive the stirring blades fixedly connected to the outside to rotate under the drive of the transmission structure, so that the plastic bottle caps are rotated and stirred in the plurality of small spaces to be separated, thereby improving the cleaning effect of the plastic bottle caps.

[0019] When the separating leakage plate moves into the cleaning tank in the present invention, since a plurality of second separating plates are fixedly connected to the bottom of the separating leakage plate, the plurality of second separating plates will move into the cleaning tank following the separating leakage plate. The plurality of second separating plates have a separating effect on the PET plastic fragments of the bottle body inside the cleaning tank, so that the PET plastic fragments of the bottle body are limited in a plurality of small spaces. Then, the third cylinder inside the protective shell is started, and the output end of the third cylinder drives the impact plate to move downward and impact the shaking plate. The shaking plate is connected to the inside of the cleaning tank through a spring, so that the shaking plate will reciprocate inside the cleaning tank under the action of the spring, and then the PET plastic fragments of the bottle body located on the shaking plate are thrown off the shaking plate, so that the PET plastic fragments of the bottle body are quickly separated from each other, facilitating the water liquid to wash the PET plastic fragments of the bottle body. In addition, a plurality of separating plates distributed in a rectangle are fixedly connected to the top of the shaking plate, and the separating plates will move upward following the shaking plate. The thrown PET plastic fragments of the bottle body can be effectively separated under the impact of the separating plates, improving the cleaning effect of the PET plastic fragments of the bottle body. When the plastic bottle caps and the PET plastic fragments of the bottle body are cleaned in the present invention, the sewage will be discharged through the third pipeline. In addition, a retaining net is arranged inside the third pipeline, and the retaining net has a blocking effect on the PET plastic fragments of the bottle body to prevent the PET plastic fragments of the bottle body from being discharged through the third pipeline.

[0020] After the cleaning of the plastic bottle cap fragments and the PET plastic fragments of the bottle body is completed in the present invention, the second pipeline no longer conveys the water liquid into the cleaning tank, and the dirty liquid inside the cleaning tank will be completely discharged through the third pipeline. Then, under the action of gravity, the plastic bottle cap fragments will fall on the partition leakage plate. The reverse rotation of the output end of the first motor will drive the drive box and the bottle cap fragment cleaning mechanism on the drive box to disengage from the cleaning tank, opening the top opening of the cleaning tank. The staff can remove the plastic bottle cap fragments on the partition leakage plate through the top opening of the cleaning tank. In addition, under the action of gravity, the PET plastic fragments of the bottle body will fall on the shaking plate. The staff opens the sealing plate through the hinge, enabling the staff to remove the PET plastic fragments of the bottle body on the shaking plate through the side opening of the cleaning tank. The present invention facilitates the removal of the plastic bottle cap fragments and the PET plastic fragments of the bottle body after cleaning and realizes the function of separating and discharging materials.

[0046] In the embodiment, the bottle cap fragment cleaning mechanism 12 includes a second motor 1201 arranged above the drive box 11. The output end of the second motor 1201 is fixedly connected to a first pulley 1202. The first pulley 1202 is connected to a second pulley 1204 through a first transmission belt 1203.

[0048] In the embodiment, the bottle body debris cleaning mechanism 13 includes a second partition plate 1301 fixedly connected to the bottom of the partition leakage plate 6. A second support plate 1302 is fixedly connected inside the cleaning tank 1. A spring 1304 is connected inside the cleaning tank 1. One end of the spring 1304 away from the cleaning tank 1 is connected to a shaking plate 1303. A protective shell 1306 is arranged inside the sealing plate 15.

[0049] In the present invention, the output end of the third cylinder 1307 drives the impact plate 1308 to move downward and impact the shaking plate 1303. The shaking plate 1303 is connected to the inside of the cleaning tank 1 through the spring 1304, so that the shaking plate 1303 will reciprocally shake inside the cleaning tank 1 under the action of the spring 1304, and then the PET plastic debris of the bottle body on the shaking plate 1303 will be thrown out from the shaking plate 1303, enabling the PET plastic debris of the bottle body to be quickly separated from each other, which is convenient for the water liquid to wash the PET plastic debris of the bottle body. In addition, a plurality of separation plates 1305 distributed in a rectangular shape are fixedly connected to the top of the shaking plate 1303. The separation plates 1305 will move upward following the shaking plate 1303, and the thrown PET plastic debris of the bottle body can be effectively separated under the impact of the separation plates 1305, improving the cleaning effect of the PET plastic debris of the bottle body.

[0050] Working principle: Step 1: In the present invention, the plastic bottle debris is first conveyed into the cleaning tank 1 through the opening at the top of the cleaning tank 1. Then, an external water delivery pipeline is connected to one end of the first pipeline 7. After opening the first control valve 8, the external water liquid will be conveyed into the water tank 9 through the first pipeline 7. Since a second pipeline 10 communicates with the water tank 9 and an electromagnetic valve is arranged on the second pipeline 10, after opening the electromagnetic valve, the water liquid will be sprayed from the water tank 9 into the cleaning tank 1 through the second pipeline 10. When the cleaning tank 1 is filled with the water liquid, the plastic bottle caps will float on the water surface, and the PET plastic debris of the bottle body will sink to the bottom of the cleaning tank 1, separating the plastic bottle caps from the PET plastic debris of the bottle body and realizing the sorting and cleaning function of the plastic bottle debris.

[0051] Step 2: When the water liquid and plastic fragments enter the inside of the cleaning tank 1 in the present invention, the first cylinder 202 is started. The output end of the first cylinder 202 will drive the connecting plate 203 to do reciprocating motion. Since the connecting plate 203 is fixedly connected to the bottom of the cleaning tank 1, the cleaning tank 1 will be driven to do reciprocating motion. In addition, the first sliding plate 204 fixedly connected to the bottom of the cleaning tank 1 will slide in the first guiding groove 205 opened at the top of the base 201, thereby improving the stability of the cleaning tank 1 during movement. While shaking the cleaning tank 1, the present invention will drive the plastic fragments inside the cleaning tank 1 to disperse in the water liquid, so that the plastic fragments can be evenly distributed inside the cleaning tank 1, realizing the function of uniform feeding.

[0052] Step 3: When the plastic fragments of the bottle caps and plastic bottles will float on the water surface and the plastic fragments of the bottle body PET sink to the bottom of the cleaning tank 1 in the present invention, the second cylinder 5 fixedly installed on the L-shaped bracket 4 is started. The output end of the second cylinder 5 will drive the partition leak plate 6 into the inside of the cleaning tank 1. The partition leak plate 6 has a partitioning effect on the plastic fragments of the bottle caps and plastic bottles. The plastic fragments of the bottle caps and plastic bottles will be cleaned above the partition leak plate 6, and the plastic fragments of the bottle body PET will be cleaned below the partition leak plate 6, improving the cleaning effect on the plastic bottle fragments.

[0053] Step 4: When the partition leak plate 6 enters the inside of the cleaning tank 1 to partition the plastic fragments of the bottle caps and plastic bottles from the plastic fragments of the bottle body PET in the present invention, the first motor 302 is started. The output end of the first motor 302 will drive the worm 303 to rotate. Since a worm gear 304 is meshed on the outer side of the worm 303, the worm gear 304 and the transmission lead screw 305 fixedly connected to the inside of the worm gear 304 will be driven to rotate. Under the action of the lead screw nut 306 and the second guiding groove 308, the second sliding plate 307 will be driven to move downward. Since one end of the second sliding plate 307 is fixedly connected to the driving box 11 and the bottle cap fragment cleaning mechanism 12 is arranged on the driving box 11, the bottle cap fragment cleaning mechanism 12 can be driven to extend into the inside of the cleaning tank 1 and be located above the plastic fragments of the bottle caps and plastic bottles.

[0054] Step Five: When the cap fragment cleaning mechanism 12 of the present invention moves above the cap and plastic bottle fragments, the limiting plate 1209 on the cap fragment cleaning mechanism 12 has a limiting effect on the top of the cap and plastic bottle fragments, and the separation leakage plate 6 has a limiting effect on the bottom of the cap and plastic bottle fragments, so that the cap and plastic bottle fragments are limited between the limiting plate 1209 and the separation leakage plate 6. In addition, a plurality of first separation plates 1210 fixedly connected to the bottom of the limiting plate 1209 will divide the limiting space into a plurality of small spaces. At this time, the second motor 1201 is started, and the output end of the second motor 1201 will drive the first pulley 1202 to rotate. Since the first pulley 1202 is connected to the second pulley 1204 through the first transmission belt 1203, the second pulley 1204 and the stirring shaft 1205 inside the second pulley 1204 will be driven to rotate. There are a plurality of stirring shafts 1205, and the plurality of stirring shafts 1205 are connected through the third pulley 1207 and the second transmission belt 1208, so that the plurality of stirring shafts 1205 can drive the stirring blades 1206 fixedly connected to the outside to rotate under the drive of the transmission structure, so that the cap and plastic bottle fragments are rotated and stirred and separated in a plurality of small spaces, thereby improving the cleaning effect of the cap and plastic bottle fragments.

[0055] Step Six: When the separation leakage plate 6 of the present invention moves into the cleaning box 1, since a plurality of second separation plates 1301 are fixedly connected to the bottom of the separation leakage plate 6, the plurality of second separation plates 1301 will move into the cleaning box 1 following the separation leakage plate 6. The plurality of second separation plates 1301 have a separating effect on the PET plastic fragments of the bottle body inside the cleaning box 1, so that the PET plastic fragments of the bottle body are limited in a plurality of small spaces. Then, the third cylinder 1307 inside the protective shell 1306 is started, and the output end of the third cylinder 1307 will drive the impact plate 1308 to move downward and impact the shaking plate 1303. The shaking plate 1303 is connected to the inside of the cleaning box 1 through the spring 1304, so that the shaking plate 1303 will reciprocate inside the cleaning box 1 under the action of the spring 1304, and then the PET plastic fragments of the bottle body located on the shaking plate 1303 will be thrown from the shaking plate 1303, so that the PET plastic fragments of the bottle body are quickly separated from each other, facilitating the water liquid to wash the PET plastic fragments of the bottle body. In addition, a plurality of separation plates 1305 distributed in a rectangle are fixedly connected to the top of the shaking plate 1303, and the separation plates 1305 will move upward following the shaking plate 1303. The thrown PET plastic fragments of the bottle body can be effectively separated under the impact of the separation plates 1305, improving the cleaning effect of the PET plastic fragments of the bottle body.

[0056] Step Seven: When the cap and plastic bottle fragments and the PET plastic fragments of the bottle body are cleaned, the sewage will be discharged through the third pipeline 1309. In addition, a retaining net 1311 is arranged inside the third pipeline 1309, and the retaining net 1311 has a blocking effect on the PET plastic fragments of the bottle body to prevent the PET plastic fragments of the bottle body from being discharged through the third pipeline 1309.

[0057] Step Eight: After the cleaning of the cap plastic bottle fragments and the bottle body PET plastic fragments of the present invention is completed, the second pipeline 10 no longer conveys the liquid to the inside of the cleaning tank 1, and the waste liquid inside the cleaning tank 1 will be completely discharged through the third pipeline 1309. Then, under the action of gravity, the cap plastic bottle fragments will fall on the partition leakage plate 6, and the reverse rotation of the output end of the first motor 302 will drive the drive box 11 and the cap fragment cleaning mechanism 12 on the drive box 11 to disengage from the cleaning tank 1, so that the top opening of the cleaning tank 1 is opened, and the staff can remove the cap plastic bottle fragments on the partition leakage plate 6 through the top opening of the cleaning tank 1. In addition, the bottle body PET plastic fragments will fall on the shaking plate 1303 under the action of gravity, and the staff opens the sealing plate 15 through the hinge 14, so that the staff can remove the bottle body PET plastic fragments on the shaking plate 1303 through the side opening of the cleaning tank 1. The present invention facilitates the removal of the cleaned cap plastic bottle fragments and the bottle body PET plastic fragments, and realizes the function of separating and discharging materials.
