[0002] As a kind of recyclable garbage, after people discard plastic bottles, cleaners will collect them and then conduct further treatments such as cleaning and crushing.

[0003] Existing plastic bottles generally include a bottle body and a packaging belt (which can also be called a label). Since the materials of the two are different, if they are subjected to a one-time crushing treatment, it will be unfavorable for the targeted recycling of plastics, resulting in poor treatment effects. At present, separating the bottle body and the packaging belt is usually carried out by workers, and this separation by workers will consume a large amount of working time of workers and is not conducive to the recycling efficiency of plastics.

[0040] An embodiment of the present application discloses a plastic recycling device for plastic packaging bottle processing, which adopts a fixing mechanism 1, a packaging tape separating mechanism 2 and a pumping and inflating mechanism 3, and can more conveniently separate the annular packaging tape wrapped and glued on the bottle body of the plastic bottle. There is a large difference in the material strength between the packaging bag and the plastic bottle. Therefore, different methods are required during the recycling process. After separation, the pertinence of the recycling process can be improved, thereby enhancing the recycling effect. At the same time, a cleaning mechanism 4 is adopted, which is combined with the fixing mechanism 1 and the pumping and inflating mechanism 3. When the plastic bottle is in an inflated state, its surface is relatively smooth, without wrinkles or with few wrinkles, and the inner and outer surfaces of the plastic bottle are cleaned, thereby achieving a better cleaning effect.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0042] Embodiment 1, referring to Figures 1 to 9 , a plastic recycling device for plastic packaging bottle processing provided by the present invention includes a fixing mechanism 1, a packaging tape separating mechanism 2 and a pumping and inflating mechanism 3. Among them, the fixing mechanism 1 is used to fix the plastic bottle, the packaging tape separating mechanism 2 is used to remove the packaging tape from the plastic bottle, and the pumping and inflating mechanism 3 is connected to the plastic bottle. The pumping and inflating mechanism 3 is used to fill the plastic bottle with air to expand and smooth the bottle body of the plastic bottle, and to extract the air in the plastic bottle to contract the bottle body of the plastic bottle. When the pumping and inflating mechanism 3 expands the plastic bottle, the packaging tape separating mechanism 2 contacts the packaging tape and fixes the packaging tape. When the pumping and inflating mechanism 3 contracts the plastic bottle, the plastic bottle is separated from the packaging tape, and the packaging tape separating mechanism 2 acts to remove the packaging tape from the plastic bottle

[0043] Specifically, referring to Figure 3 , Figure 4 and Figure 5, the fixing mechanism 1 includes a fixing base 101. A fixing rod 102 is vertically arranged above the fixing base 101. The diameter of the fixing rod 102 is equal to the inner diameter of the bottle mouth of the plastic bottle, and the plastic bottle can be inserted onto the fixing rod 102. When the plastic bottle is inserted and fixed, its bottle mouth faces downward. To facilitate the insertion of the plastic bottle, a tapered rod 103 is connected to the upper end of the fixing rod 102. The diameter of the lower end of the tapered rod 103 is equal to the diameter of the fixing rod 102, and the diameter of the top end of the tapered rod 103 is smaller than the diameter of the fixing rod 102, thereby providing guidance for the insertion of the plastic bottle.

[0044] Further, referring to Figure 3 , Figure 4 and Figure 5 , a sealing rod 104 is connected to the lower end of the fixing rod 102. The sealing rod 104 has the same diameter as the fixing rod 102. A sealing groove 105 is provided on the surface of the sealing rod 104, and a sealing ring 106 is arranged in the sealing groove 105. The outer diameter of the sealing ring 106 gradually increases from top to bottom. The upper end of the sealing ring 106 is flush with the surface of the fixing rod 102, and the diameter of the lower end of the sealing ring 106 is larger than the diameter of the fixing rod 102. When the bottle mouth of the plastic bottle is inserted onto the sealing ring 106, the plastic bottle can be sealed.

[0045] It should be noted that in this embodiment, for the plastic bottle to be sealed, the bottle mouth of the plastic bottle needs to be kept on the sealing ring 106. Based on this, a limiting ring 107 is further sleeved outside the sealing rod 104 in this embodiment. The limiting ring 107 is elliptical and horizontally arranged. The major axis of the limiting ring 107 is arranged horizontally. The limiting ring 107 has no contact with the fixing rod 102, and the central axis of the limiting ring 107 coincides with the axis of the fixing rod 102. A limiting chute 108 is provided on the inner wall of the limiting ring 107, and two limiting sliding seats 109 are slidably arranged in the limiting chute 108.

[0046] Meanwhile, referring to Figure 3 and Figure 6 , a rotating ring 110 is arranged below the limiting ring 107. The rotating ring 110 is coaxially sleeved outside the sealing rod 104. The rotating ring 110 has no contact with the fixing rod 102. A driving ring 111 is rotatably sleeved outside the rotating ring 110. Driving seats 112 are arranged at both ends of the driving ring 111. A driving bracket 113 is connected to the upper end of the driving seat 112. A driving cylinder 114 is arranged at the top end of the driving bracket 113. The driving cylinder 114 is located in the plane where the limiting chute 108 is located. A limiting rod 115 is slidably arranged in the driving cylinder 114. One end of the limiting rod 115 is connected to the limiting sliding seat 109, and the other end is connected to a sealing clamping plate 116.

[0047] Specifically, referring to Figure 6, a rotating motor 117 is provided on the rotating ring 110. The rotating motor 117 is in transmission connection with the driving ring 111. A sealing cylinder 118 is provided on one side of the sealing rod 104. The output end of the sealing cylinder 118 is vertically upward. Both the limiting ring 107 and the rotating ring 110 are connected to the output end of the sealing cylinder 118.

[0048] The ring below the thread of the plastic bottle mouth is the fixed ring. When the two limiting sliding seats 109 respectively move to the transverse two ends of the limiting sliding groove 108, the inner end of the limiting rod 115 is in a contracted state, and the distance between the two sealing clamping plates 116 is greater than the diameter of the fixed ring. In this state, the output end of the sealing cylinder 118 extends, and the sealing clamping plates 116 can be driven to move above the fixed ring.

[0049] When the two limiting sliding seats 109 respectively move to the longitudinal two ends of the limiting sliding groove 108, the inner end of the limiting rod 115 is in an extended state, and the distance between the two sealing clamping plates 116 is greater than the outer diameter of the plastic bottle mouth but less than the diameter of the fixed ring. In this state, the output end of the sealing cylinder 118 retracts, and the fixed ring and the plastic bottle can be driven to move downward, so that the plastic bottle is in close contact with the sealing ring 106 to achieve sealing.

[0050] Through the above settings, when the plastic bottle is not inserted on the fixed rod 102, the sealing cylinder 118 is in a contracted state, and the limiting ring 107 and the rotating ring 110 are located at the lower part of the sealing rod 104. At this time, the limiting sliding seat 109 is located at the transverse two ends of the limiting sliding groove 108, the inner end of the limiting rod 115 is in a contracted state, and the distance between the two sealing clamping plates 116 is greater than the diameter of the fixed ring.

[0051] When the plastic bottle is inserted on the fixed rod 102 and the bottle mouth is inserted on the upper part of the sealing rod 104, the output end of the sealing cylinder 118 extends, driving the limiting ring 107 and the rotating ring 110 to move upward, so that the limiting ring 107 moves to the outside of the bottle mouth. Since the distance between the two sealing clamping plates 116 is greater than the diameter of the fixed ring, the sealing clamping plates 116 can move above the fixed ring.

[0052] After the sealing clamping plates 116 move above the fixed ring, the rotating motor 117 operates, driving the driving ring 111 to rotate 90°, so that the two limiting sliding seats 109 move to the longitudinal two ends of the limiting sliding groove 108, the inner end of the limiting rod 115 is in an extended state, and the distance between the two sealing clamping plates 116 is greater than the outer diameter of the plastic bottle mouth but less than the diameter of the fixed ring.

[0053] Then, the output end of the sealing cylinder 118 retracts, driving the limiting ring 107 and the rotating ring 110 to move downward. After the sealing clamping plate 116 moves to contact the upper surface of the fixed ring, as the output end of the sealing cylinder 118 retracts, the sealing clamping plate 116 drives the fixed ring to move downward, that is, to move the plastic bottle downward, so that the mouth of the plastic bottle is hermetically inserted into the sealing ring 106.

[0054] Further, referring to Figure 7 , in this embodiment, the packaging belt separating mechanism 2 includes a separating ring 201. The separating ring 201 is coaxial with the fixed rod 102. A plurality of pressing cylinders 202 are arranged through the separating ring 201. The pressing cylinders 202 are arranged along the radial direction of the separating ring 201. The output end of the pressing cylinder 202 faces the center of the separating ring 201. The output end of the pressing cylinder 202 is connected with a suction cup 203.

[0055] In the packaging belt separating mechanism 2 of this embodiment, when the output end of the pressing cylinder 202 extends, it can push the suction cup 203 against the surface of the plastic bottle, so as to adsorb the packaging belt.

[0056] It should be noted that before the suction cup 203 adsorbs the packaging belt, the air pumping and inflation mechanism 3 acts first, so that the plastic bottle is in an inflated state, and the body of the plastic bottle expands and becomes smooth, thus facilitating the adsorption of the suction cup 203.

[0057] Further, referring to Figure 2 , the packaging belt separating mechanism 2 further includes a telescopic cylinder 204. The telescopic cylinder 204 is vertically arranged above the conical rod 103. The output end of the telescopic cylinder 204 is vertically downward and connected with a telescopic seat 205. A rotary motor 206 is arranged on the telescopic seat 205. The rotary motor 206 is connected with a rotary plate 207. The rotary plate 207 is horizontally arranged and a plurality of vertical rods 208 are arranged on its lower surface. The plurality of vertical rods 208 are evenly distributed along the circumference of the rotary plate 207. A rotating cylinder 209 is rotatably arranged on the outer circumference of the vertical rod 208.

[0058] In the above-mentioned packaging belt separating mechanism 2, the output end of the telescopic cylinder 204 extends, driving the telescopic seat 205, the rotary motor 206, the rotary plate 207, the vertical rods 208 and the rotating cylinder 209 to move downward. The plurality of vertical rods 208 are distributed in a circular shape, and this circle is coaxial with the fixed rod 102, that is, coaxial with the plastic bottle.

[0059] It should be noted that after the suction cup 203 adsorbs the packaging tape, the air pumping and inflating mechanism 3 further operates to extract the air inside the plastic bottle, causing the bottle body of the plastic bottle to shrink and the bottle body to separate from the packaging tape. At this time, the output end of the telescopic cylinder 204 extends to drive the vertical rod 208 and the rotating cylinder 209 to insert into the gap between the bottle body and the packaging tape. Then, the rotating motor 206 operates to drive the rotating plate 207, the vertical rod 208, and the rotating cylinder 209 to rotate. After the rotating cylinder 209 rotates to the adhesive part between the packaging tape and the bottle body, the rotation of the rotating cylinder 209 separates the adhesive part, thereby removing the packaging tape from the bottle body, and the packaging tape adheres to the rotating cylinder 209.

[0060] Further, referring to Figure 4 and Figure 5 , the air pumping and inflating mechanism 3 includes an air vent passage 301 opened in the fixed rod 102. The air vent passage 301 extends into the conical rod 103 and the sealing rod 104. The air vent passage 301 is connected with an air inlet pipe 302 and an air outlet pipe 303. The air inlet pipe 302 is connected with an air inflator 304, and the air outlet pipe 303 is connected with an air extractor 305.

[0061] A three-way valve is connected between the air vent passage 301, the air inlet pipe 302, and the air outlet pipe 303 to control the connection of the three. When the air inlet pipe 302 is connected to the air vent passage 301, the end of the conical rod 103 outputs air. When the air outlet pipe 303 is connected to the air vent passage 301, the end of the conical rod 103 extracts air.

[0062] It should be noted that in this embodiment, by setting the fixing mechanism 1, the packaging tape separating mechanism 2, and the air pumping and inflating mechanism 3, the annular packaging tape wrapped and adhered to the bottle body of the plastic bottle can be separated more conveniently. There is a large difference in the material strength between the packaging bag and the plastic bottle. Therefore, different methods are required during the recycling process. After separation, the pertinence of the recycling process can be improved, thereby enhancing the recycling effect.

[0063] Embodiment 2, referring to Figures 1 to 9 , based on the above-set fixing mechanism 1 and air pumping and inflating mechanism 3, when the plastic bottle is in an inflated state, a cleaning mechanism 4 is further set. Since the surface of the plastic bottle is relatively smooth and has no or few wrinkles when it is in an inflated state, the cleaning effect is better when cleaning in this state.

[0064] Specifically, referring to Figure 7 , Figure 8 and Figure 9The cleaning mechanism 4 includes a lifting cylinder 401, which is vertically arranged on one side of the fixed rod 102. The output end of the lifting cylinder 401 is vertically upward and connected to a horizontal ring 402. The horizontal ring 402 is coaxial with the fixed rod 102. The inner surface of the horizontal ring 402 is provided with an annular groove 403. A cleaning ring 404 is slidably arranged in the annular groove 403. A cleaning brush is arranged on the inner surface of the cleaning ring 404. A cleaning motor 405 is arranged on the side of the horizontal ring 402. An annular rack 406 is arranged on the side of the cleaning ring 404. The cleaning motor 405 is transmission-connected to the annular rack 406.

[0065] In the above-mentioned cleaning mechanism 4, the cleaning motor 405 can drive the annular rack 406 to rotate when working, and the annular rack 406 drives the cleaning ring 404 to rotate, so that the brush continuously brushes the surface of the plastic bottle, thereby cleaning the outer surface of the plastic bottle.

[0066] Further, refer to Figure 5 The cleaning mechanism 4 further comprises a cleaning nozzle 407, which is arranged at the top of the tapered rod 103. A cleaning channel 408 is arranged inside the tapered rod 103. The cleaning channel 408 is connected to the cleaning nozzle 407, and the cleaning channel 408 is connected to a cleaning pipe 409. In the above cleaning mechanism 4, the cleaning pipe 409 is connected to a cleaning water tank filled with cleaning liquid. A water pump is also arranged, and the water outlet of the water pump is connected to the cleaning pipe 409. When the water pump is working, the cleaning liquid can be pumped into the cleaning pipe 409, and the cleaning liquid is sprayed from the cleaning nozzle 407 and sprayed on the inner wall of the plastic bottle.

[0067] A reflux channel is also provided inside the fixed rod 102, and the reflux channel extends to the tapered rod 103 and the sealing rod 104. After the cleaning liquid cleans the inner wall of the plastic bottle, it gathers at the bottle mouth under gravity. When the water pump no longer pumps in the cleaning liquid, the cleaning liquid flows out from the reflux channel.

[0068] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0069] The present application can conveniently separate the annular packaging belt wrapped and glued to the body of the plastic bottle by setting a fixing mechanism 1, a packaging belt separation mechanism 2 and a pumping and inflating mechanism 3. The material strength of the packaging bag and the plastic bottle is quite different, so different methods need to be adopted during recycling. After separation, the targetedness of the recycling can be improved, thereby improving the recycling effect.

[0070] At the same time, the present application uses a cleaning mechanism 4, which is combined with the fixing mechanism 1 and the pumping and inflation mechanism 3. It utilizes the fact that the surface of the plastic bottle is relatively smooth when it is in an inflated state, with no wrinkles or few wrinkles, to clean the inner and outer surfaces of the plastic bottle, thereby achieving a better cleaning effect.

[0071] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.

[0072] The above is only a preferred specific embodiment of the embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application, according to the technical solution and its concept of the present application, makes equivalent replacements or changes, and should be covered by the protection scope of the present application.
