Description

Technical Field

[0001] This invention relates to the field of material recycling technology, specifically to an automated storage device for a plastic bottle recycling robot. Background Technology

[0002] In open, flat spaces such as stadiums, there are often a large number of discarded beverage bottles. Some of these bottles may contain liquids, debris, or other substances. Liquid residue can breed insects, produce odors, or leak. Therefore, recycling machines are needed to collect and store these plastic bottles.

[0003] When recycling plastic bottles, the large size of the bottles may prevent the robot from processing large quantities quickly. Therefore, it needs to be paired with appropriate storage equipment to compress and store the bottles as the robot moves, extending its continuous working time. While compressing empty bottles, this process is more efficient. However, for bottles containing liquid, the liquid needs to be drained, which takes time. Therefore, when processing large quantities of bottles, different methods must be used for bottles in different states to ensure the fastest possible storage. Furthermore, if impurities remain after draining the liquid from the bottles, the quality of the recycled bottles will be affected, hindering subsequent resource utilization.

[0004] Therefore, it is necessary to invent an automated collection device for plastic bottle recycling robots to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic collection device for plastic bottle recycling robots. By screening during the bottle recycling process, it achieves automatic sorting, drainage, and compression of empty and heavy bottles in an integrated manner, thereby improving recycling efficiency and quality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0010] As a preferred embodiment of an automatic storage device for a plastic bottle recycling robot, a rack is installed at the bottom of the positioning slider, a guide plate is fixedly installed inside the storage box to support the positioning slider, racks are provided on the inner sides of the adjusting arms on both sides, and a synchronous gear is rotatably installed at the bottom of the positioning slider, which meshes with racks on both sides respectively; when the positioning slider moves towards the discharge end of the heavy bottle processing section, the corresponding positioning slider slides in the opposite direction.

[0011] As a preferred embodiment of an automatic storage device for a plastic bottle recycling robot, both of the positioning sliders are equipped with synchronous push blocks on their sides. The synchronous push blocks extend to the outside of the storage box, and the two synchronous push blocks extend inward. A rack three is installed on the inner side of the extended end of the synchronous push blocks, and the storage box is rotatably equipped with a synchronous gear two that can simultaneously mesh with the rack three on both sides.

[0012] As a preferred embodiment of an automatic storage device for a plastic bottle recycling robot, the empty bottle storage unit includes a positioning block, a cutting blade, and a compression push plate. A positioning block for fixing the bottle is installed on one side of the empty bottle side guide plate of the storage box. The cutting blade is slidably disposed at the bottom end of the empty bottle side guide plate. A groove for storing the cutting blade head is opened at the bottom end of the positioning block. The compression push plate is installed on the vertical surface of the empty bottle side guide plate and connected to the telescopic end of the cylinder. A cavity is left between the empty bottle side guide plate and the storage box for the bottle to fall after compression.

[0013] As a preferred embodiment of an automatic storage device for a plastic bottle recycling robot, the extrusion section includes an extrusion roller and a drive motor. The extrusion roller is located below the second extrusion push plate and close to the side of the motor mounting wall inside the storage box, and the drive motor is mounted on one side of the extrusion roller.

[0014] As a preferred embodiment of an automatic storage device for a plastic bottle recycling robot, the cutting section is located below the side baffle and includes lead screws rotatably mounted on both sides of the discharge end of the heavy bottle processing section and synchronous sliders threadedly connected to the lead screws on both sides. The top of the synchronous slider is equipped with a blade for cutting the bottle body. One end of the lead screw extends to the outside of the storage box and is equipped with a bevel gear. A transmission rod is rotatably mounted on the outside of the storage box, and bevel gears are respectively installed at both ends of the transmission rod, which mesh with bevel gears.

[0016] As a preferred embodiment of an automatic collection device for a plastic bottle recycling robot, the wastewater collection unit further includes a water-gathering slope located at the bottom of the empty bottle side guide plate. A drain hole is provided on one side of the side wall of the collection box located at the bottom of the water-gathering slope. A water-gathering hole is provided on one side of the side wall of the collection box located on the U-shaped water-collecting plate. A water-collecting channel is provided on the outside of the collection box. The two ends of the water-collecting channel are respectively connected to the drain hole and the water-gathering hole. A filter plate for collecting debris is provided on the inner side of the U-shaped water-collecting plate.

[0017] The beneficial effects of this invention are as follows: Bottles are sorted by gravity, empty bottles, bottles containing water, and bottles containing impurities are screened, and the corresponding bottles are processed in different ways. When processing bottles containing water, the bottom of the bottle is cut, and the bottle is lifted by clamping. Gas is injected into the open bottle through an injection needle to quickly expel the liquid inside. After injection, the weight of the bottle is detected by a weighing sensor. By comparing the weight after drainage, it is determined whether the bottle contains large-volume impurities that cannot be drained. This method of injection drainage + weighing comparison provides automated quantitative detection of the drainage effect, improving the processing efficiency of the bottles and avoiding problems such as damage to the equipment casing or equipment jamming during bottle compression and storage, which could affect the normal operation of the equipment.

[0044] refer to Figures 1 to 12This invention provides an automatic storage device for a plastic bottle recycling robot, including a storage box 3 connected to the end of a bottle recycling robot 1. The top of the storage box 3 has a bottle storage opening, and the bottom of the bottle storage opening has a gravity sorting component 4 for sorting empty bottles and heavy bottles containing water. On both sides of the gravity sorting component 4 are respectively provided an empty bottle storage section 6 for processing empty bottles and a heavy bottle processing section 7 for processing heavy bottles. The heavy bottle processing section 7 includes a cutting section 8 for cutting the bottle body and a lifting section for clamping and lifting the bottle body. The lifting section includes a clamping block 701, which has a diameter smaller than the bottle body and larger than the bottle... The cap has a circular groove 704, inside which are installed multiple gas injection needles 703 for piercing the cap. The gas injection needles 703 are connected to the gas output end 5 through a gas supply pipe 702. The lifting part also includes a weighing sensor 708 for weighing the bottle body. The bottom end of the heavy bottle processing part 7 is provided with a wastewater collection part 12. The top end of the wastewater collection part 12 is provided with a heavy bottle sorting part 9 for sorting empty bottles after drainage and heavy bottles containing impurities after drainage. The heavy bottle sorting part 9 includes a sorting slider 901 that can slide to the feeding end of the heavy bottle processing part 7. Both output ends of the heavy bottle sorting part 9 are provided with squeezing parts for compressing the bottle body. An air pump is installed on one side of the storage opening of the storage box 3. The air pump injects air into the air injection needle 703 through the air supply pipe 702. The extrusion part located on the side of the impurity bottle is relatively reinforced to avoid jamming the equipment when compressing the impurity bottle. The weighing sensor 708 is used to measure the weight of the bottle after drainage.

[0045] The heavy bottle processing unit 7 includes two side baffles 710 for storing bottles. A positioning slider 909 for supporting the bottle is slidably mounted on the bottom end of each side baffle 710. The positioning sliders 909 on both sides can slide inwards or outwards synchronously. An inclined surface for supporting the gravity sorting component 4 is provided at the top end of each side baffle 710. Clamping blocks 701 are located on both sides of the side baffles 710. Rectangular slots are respectively opened at both ends of the storage box 3. Slide rails 709 are installed on both sides of the rectangular slots. Mounting plates 707 are slidably mounted on the slide rails 709. A cylinder 705 for pushing the clamping blocks 701 to clamp the bottle is mounted on the mounting plate 707. A weighing sensor 708 is fixedly mounted on the bottom end of the mounting plate 707. A cylinder 706 for lifting the mounting plate 707 is provided at the bottom end of the weighing sensor 708. The cylinders 705, weighing sensor 708, and cylinder 706 on both sides operate synchronously via a controller. The heavy bottle processing unit 7 is used to receive and fix the bottle body, which facilitates the subsequent cutting of the bottle body. It is also used to sort and weigh the bottle body. By setting the air injection needle 703, the bottle body is injected with air to achieve the purpose of rapid drainage.

[0046] The wastewater collection unit 12 includes a U-shaped water collection plate 1205 located at the discharge end of the heavy bottle processing unit 7. Guide plates 913 for sliding the sorting slider 901 are respectively provided on both sides of the top of the U-shaped water collection plate 1205. The upper half of the sorting slider 901 is inclined, and the lower half is provided with a compression push plate 904 for compressing the bottles. Adjusting arms 903 are respectively installed on both sides of the sorting slider 901. Both adjusting arms 903 are connected to a cylinder push plate 902, which is connected to the output end of a cylinder. The crossbar of the adjusting arm 903 is located above the cutting unit 8. The sorting slider 901 is responsible for performing secondary sorting and, while moving the sorting position, automatically controls the opening and closing of the upper positioning slider 909 to release the bottles.

[0047] The bottom end of the positioning slider 909 is equipped with a rack 908. A guide plate 906 for supporting the positioning slider 909 is fixedly installed inside the storage box 3. Racks 905 are provided on the inner sides of the adjusting arms 903 on both sides. A synchronous gear 907 is rotatably mounted on the bottom end of the positioning slider 909, and the synchronous gear 907 meshes with the racks 905 and 908 on both sides respectively. When the positioning slider 909 moves towards the discharge end of the heavy bottle processing section 7, the corresponding positioning slider 909 slides in the opposite direction. Through the above-mentioned linkage mechanism, it is ensured that after the bottles are drained and weighed, they can be seamlessly and reliably transferred from a fixed position to the sorting slider 901.

[0048] Both positioning sliders 909 are equipped with synchronous push blocks 910 on their sides. The synchronous push blocks 910 extend to the outside of the storage box 3, and both synchronous push blocks 910 extend inward. A rack 912 is installed on the inner side of the extended end of the synchronous push blocks 910. The storage box 3 is rotatably equipped with a synchronous gear 911 that can simultaneously mesh with the racks 912 on both sides. Through the linkage between the synchronous push blocks 910 and the racks 908, when the sorting slider 901 slides inward, it can drive the positioning slider 909 to slide outward synchronously, ensuring the drop of the bottle and forming a complete control chain.

[0049] The empty bottle storage unit 6 includes a positioning block 601, a cutting blade 602, and a compression pusher plate 603. The positioning block 601 for fixing the bottle body is installed on one side of the empty bottle side guide plate of the storage box 3. The cutting blade 602 is slidably disposed at the bottom end of the empty bottle side guide plate. The bottom end of the positioning block 601 has a groove for storing the cutting blade head of the cutting blade 602. The compression pusher plate 603 is installed on the vertical surface of the empty bottle side guide plate and connected to the telescopic end of the cylinder. A cavity is left between the empty bottle side guide plate and the storage box 3 for the bottle body to fall after compression.

[0050] The extrusion section includes an extrusion roller 1002 and a drive motor 1003. The extrusion roller 1002 is located below the extrusion push plate 904 and near the motor mounting wall inside the storage box 3. The drive motor 1003 is mounted on one side of the extrusion roller 1002. The sorting slider 901 is also used to initially compress the bottle body to facilitate subsequent processing by the extrusion roller 1002.

[0051] The cutting section 8 is located below the side baffle 710 and includes lead screws 801 rotatably mounted on both sides of the discharge end of the heavy bottle processing section 7 and synchronous sliders 802 threadedly connected to both lead screws 801. A blade 803 for cutting the bottle is mounted at the top of the synchronous slider 802. One end of the lead screw 801 extends to the outside of the storage box 3 and is equipped with a bevel gear 804. A transmission rod 805 is rotatably mounted on the outside of the storage box 3, and two bevel gears 806 meshing with the bevel gear 804 are mounted at both ends of the transmission rod 805. After cutting the bottle, the cutting section 8 moves to the side away from the bottle to prevent the bottle from being intercepted by the synchronous slider 802 during its descent.

[0052] The gravity sorting assembly 4 includes a hinge plate 401 and a counterweight 402. The inlet of the storage box 3 is located on the side of the hinge plate 401 near the heavy bottle processing section 7, and the counterweight 402 is located at the bottom end of the hinge plate 401 near the empty bottle storage section 6. The gravity sorting assembly 4 can also improve sorting accuracy by first weighing the bottles and then controlling the rotation of the hinge plate 401 to the corresponding direction via a motor after weighing.

[0053] The wastewater collection unit 12 also includes a water-gathering inclined surface 1203 located at the bottom end of the empty bottle side guide plate. A drain hole 1201 is provided on one side of the storage box 3 at the bottom end of the water-gathering inclined surface 1203. A water-gathering hole 1202 is provided on one side of the storage box 3 at the U-shaped water-collecting plate 1205. A water-collecting channel 1204 is provided on the outer side of the storage box 3, with both ends of the channel communicating with the drain hole 1201 and the water-collecting hole 1202, respectively. A filter plate 1206 for collecting debris is provided on the inner side of the U-shaped water-collecting plate 1205. The wastewater collection unit 12 is used to recycle wastewater from the bottles inside the storage box 3. The filter plate 1206 is slidably installed on the inner side of the U-shaped water-collecting plate 1205, and a drain outlet is connected to the bottom end of the U-shaped water-collecting plate 1205.

[0054] During the operation of the bottle recycling robot 1 of this invention, the transfer claw 2 transports the bottle to the inlet of the storage box 3. When the bottle enters the gravity sorting component 4, the weight of the empty bottle is light and cannot press down the hinge plate 401. It slides into the empty bottle storage part 6 along the inclined surface. When it encounters a bottle containing water or impurities, its weight presses down the hinge plate 401 and slides into the heavy bottle processing part 7. The heavy bottle enters the channel formed by the side baffle 710. The positioning slider 909 at the bottom extends from both sides to support and fix the bottle body. The cutting part 8 below is activated, and the blade 803 moves under the drive of the screw 801 to open at the bottom of the bottle body for subsequent drainage.

[0055] The two clamping blocks 701 move towards the center under the push of cylinder 705, and the circular groove 704 clamps the bottle opening below the cap, securing the bottle. The entire clamping mechanism is then lifted upwards by cylinder 706, raising the bottle and exposing the opening for drainage. The air injection needle 703 inside the clamping block 701 pierces the cap during clamping. An external air source injects gas into the bottle through the air supply pipe 702, increasing the internal pressure and forcibly expelling the liquid from the cut opening. The lifting mechanism integrates a weighing sensor 708, which weighs the bottle after drainage to determine its mass. Based on the weighing result, the sorting slider 901 of the heavy bottle sorting section 9 slides to the corresponding position, guiding the bottle into different processing channels. The extrusion push plate 904 at the bottom of the sorting slider 901 can initially compress the bottle during contraction, facilitating the compression and storage of the bottle by the lower extrusion roller 1002.

[0056] When the sorting slider 901 sorts, it drives the corresponding positioning slider 909 to slide in the opposite direction via a gear and rack mechanism. When the sorting slider moves to one side to receive a bottle, it will drive the positioning sliders 909 on both sides to retract synchronously, making way for the bottle to fall. The whole process is automatic and synchronized, requiring no additional control.

[0057] It should be stated that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to the present invention. However, such variations, as long as they do not depart from the spirit of the present invention, should be within the scope of protection of the present invention. Furthermore, some terminology used in this specification and claims is not limiting, but merely for ease of description.
