Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a recycling and processing device for plastics and cardboard boxes. Background Technology

[0002] Recyclable waste refers to recyclable resources that can be recycled and reused, including paper, cardboard, and plastic products that are reusable in themselves or in terms of their materials.

[0003] Currently, plastic products and cardboard boxes constitute a large proportion of recyclable waste. Due to their hollow structure, plastic products, and due to the varying sizes of cardboard boxes, are difficult to store or take up a lot of space when stored. Furthermore, after being collected in the community, existing plastic and cardboard products still require secondary sorting at waste recycling stations, which is quite cumbersome.

[0004] Currently, there is a lack of recycling equipment that can uniformly sort and process recyclable waste such as plastic products and cardboard boxes, control their volume, and avoid secondary sorting at waste recycling stations. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides an energy-saving recycling device for renewable resources to solve at least one of the above technical problems.

[0006] To achieve the above objectives, this utility model provides an energy-saving recycling equipment for renewable resources, characterized in that it includes two parallel plastic product processing channels and a cardboard product processing channel.

[0007] The plastic product processing channel passes through a first crusher, a first conveying mechanism, and a first hopper.

This facilitates centralized processing of recyclable waste within the community, controlling volume and eliminating the need for secondary sorting.

[0011] More preferably, the compression assembly includes a support base plate on which two front side plates and a rear side plate are mounted side by side.

The upper pressure plate is connected to the telescopic rod of the longitudinal telescopic cylinder, and the upper pressure plate is arranged vertically above and below the support base plate.

[0017] This invention optimizes the structure of the compression mechanism, making it easier to apply force to the left and right sides of the object to be compressed through the left and right compression mechanisms, and then apply pressure to the top of the object to be compressed through the downward pressure of the upper compression mechanism, thereby compressing it into a final block structure.

[0018] Meanwhile, this invention achieves the ejection of the compressed block structure by the synchronous rightward movement of the left and right compression mechanisms.

[0020] The upper pressure plate is equipped with a spraying mechanism for wetting cardboard products, and the spraying direction of the spraying mechanism is downward.

[0021] By combining water spraying and heating, the product is compressed and shaped without the need for secondary addition of packaging materials.

[0022] More preferably, a water seepage hole is formed on the support substrate;

[0023] A water collection tank is installed directly below the supporting base plate.

[0024] It facilitates the collection of seepage water during the compression process.

[0025] More preferably, a guide post is installed on the upper pressure plate;

[0033] A further preferred option includes a cutting device;

[0034] The cutting device is located on one side of the cardboard product processing channel.

[0035] This facilitates the initial cutting of recyclable waste to be processed, thus controlling its volume.

[0036] More preferably, a first weighing hopper is installed between the first crusher and the feed end of the first conveying mechanism;

Detailed Implementation

[0046] The present invention will be further described below with reference to the accompanying drawings.

[0047] See Figures 1 to 4 Specific Embodiment 1: A renewable resource energy-saving recycling device includes two parallel plastic product processing channels 1 and cardboard product processing channels 2. The plastic product processing channel 1 includes a first crusher 11, a first conveying mechanism 12, and a first hopper 13. The inlet end of the first conveying mechanism 12 connects to the bottom outlet of the first crusher 11, and the outlet end of the first conveying mechanism 12 connects to the first hopper 13. The cardboard product processing channel 2 includes a second crusher 21, a second conveying mechanism 22, and a second hopper 23. The inlet end of the second conveying mechanism 22 connects to the bottom outlet of the second crusher 21, and the outlet end of the second conveying mechanism 22 connects to the second hopper 23. A control valve is installed at the bottom of both the first hopper 13 and the second hopper 23. A weighing hopper 3 is connected below the first hopper 13 and the second hopper 23, and the outlet end of the weighing hopper 3 connects to a compression assembly 4. This invention crushes plastic and cardboard products, then compresses them using the compression assembly 4 to form paper or plastic blocks respectively. This facilitates centralized processing of recyclable waste within the community, controlling volume and eliminating the need for secondary sorting. The first shredder is a PE shredder. The second shredder is a waste cardboard shredder.

[0048] Both the first and second conveying mechanisms are inclined upwards from left to right. Baffles are arranged along the conveying direction on the conveyor belts of both mechanisms. The lower right ends of the first conveying mechanism 12 and the second conveying mechanism 22 are directly opposite the first hopper 13 and the second hopper 23, respectively. The upper opening of the weighing hopper is directly opposite the outlet of the first hopper 13 and the second hopper 23.

[0049] The compression assembly 4 includes a support base plate on which two front side plates 41 and a rear side plate 42 are mounted side-by-side. A left compression mechanism 43 and a right compression mechanism 44 are mounted on the support base plate in a mirror-symmetrical arrangement. The left compression mechanism 43 includes a left telescopic cylinder and a left sliding plate, with the telescopic rod of the left telescopic cylinder connected to the left sliding plate. The right compression mechanism includes a right telescopic cylinder and a right sliding plate, with the telescopic rod of the right telescopic cylinder connected to the right sliding plate. The left and right sliding plates are slidably positioned between the front and rear side plates. An upper compression mechanism 45 is also mounted on the support base plate. The upper compression mechanism 45 includes a longitudinal telescopic cylinder and an upper pressure plate, with the upper pressure plate connected to the telescopic rod of the longitudinal telescopic cylinder. The upper pressure plate is positioned vertically above and below the support base plate. This invention optimizes the structure of the compression mechanism, facilitating the application of force to the left and right sides of the object to be compressed via the left and right compression mechanisms 43 and 44, followed by downward pressure from the upper compression mechanism 45, thereby compressing the object into a final block-shaped structure. Simultaneously, the synchronous rightward movement of the left and right compression mechanisms enables the ejection of the compressed block-shaped structure.

[0050] Heating wires are fixed inside the front side panel 41, rear side panel 42, left slide plate, and right slide plate. Heating wires are also fixed to the upper fixed plate. A spray mechanism 46 for wetting cardboard boxes is installed on the upper pressure plate, with the spray direction of the spray mechanism 46 facing downwards. Through the combination of spraying water and heating, compression and shaping are achieved without the need for secondary addition of auxiliary packaging materials. The addition of the spray mechanism wets the cardboard, improving the compression effect of the cardboard boxes in the later stages. The spray mechanism includes spray heads, and four spray heads can be provided. Guide columns are installed on the upper pressure plate. An upper support plate is connected to the support base plate via the support columns, and the guide columns are slidably connected to the upper support plate. A longitudinal telescopic cylinder is installed on the upper support plate. The telescopic rod of the longitudinal telescopic cylinder passes through the upper support plate and is connected to the upper pressure plate. The spray mechanism can spray simultaneously when the lower pressure plate is pressed down, or spray before the lower pressure plate is pressed down, or spray after the lower pressure plate is pressed down.

[0051] A drainage hole is formed on the support base plate; a water collection tank is installed directly below the support base plate to facilitate the collection of water seepage during the compression process. The water collection tank is directly opposite the drainage hole. The drainage hole is located on the support base plate in the area directly opposite the upper pressure plate. The upper pressure plate is provided with an upper pressure part for longitudinal sliding in the space enclosed by the front side plate, rear side plate, left sliding plate, and right sliding plate.

[0052] The left limit position of the left sliding plate is directly opposite the left side of the valve outlet of the weighing hopper, and the right limit position of the left sliding plate is directly opposite the right side of the upper pressure plate. This facilitates the pushing of material from the weighing hopper side to the compression assembly 4 by sliding the left sliding plate to the right, and then pushing it outward from the compression assembly 4, thus facilitating the ejection of the compressed block. The left sliding plate has three sliding positions, namely the left limit position, the middle position (compression position), and the right limit position, arranged from left to right. The right sliding plate has two sliding positions, namely the left sliding position (compression position) and the right sliding position. The left sliding position (compression position) and the middle position (compression position) are both located in the area between the front and rear side plates. The right limit position is located on the right side of the area between the front and rear side plates.

[0053] First, the left slide plate is at its left limit position. After the material is discharged from the valve outlet of the weighing hopper, the left slide plate slides to the right to the middle position (compression position), and the right slide plate slides from the left to the left sliding position (compression position). The lower pressure plate presses down to perform the compression process. After compression, the upper pressure plate rises to the upper limit position, the left slide plate slides to the right to the right limit position, and the right slide plate slides to the right to the right sliding position. The compressed product is then moved out of the area between the front and rear side plates.

[0054] A valve is installed at the bottom of the weighing hopper 3. Once the weight value sensed by the weighing hopper 3 exceeds a set value, the valve opens. The valve faces the area between the front side plate 41 and the rear side plate 42. The valve outlet at the bottom of the weighing hopper 3 and the upper compression mechanism are located in the area between the front and rear side plates. This facilitates the transfer of material from the valve outlet of the weighing hopper to directly below the upper compression mechanism via the rightward movement of the left compression mechanism. Simultaneously, the compressed material is pushed to the right, pushing it out of the area between the front and rear side plates.

[0055] It also includes a stacking mechanism 5, which includes a clamping mechanism for holding the compressed finished product. The clamping mechanism is mounted on the three-dimensional transfer mechanism. This facilitates the transfer of the compressed finished product to the appropriate position via the three-dimensional transfer mechanism. It also includes a frame with a storage platform 51, located above the plastic product processing channel 1 and the cardboard product processing channel 2. The three-dimensional transfer mechanism is used to transfer items from the compression assembly 4 to the storage platform. The three-dimensional transfer mechanism includes a gantry and a three-dimensional translation mechanism mounted on the gantry.

[0056] It also includes a cutting device 6; the cutting device 6 is located on one side of the cardboard product processing channel 2. This facilitates the preliminary cutting of recyclable waste to be processed, controlling its volume.

[0057] A first weighing hopper is installed between the feed ends of the first crusher 11 and the first conveying mechanism 12; a second weighing hopper 24 is installed between the feed ends of the second crusher 21 and the second conveying mechanism 22. The bottom of both the first and second weighing hoppers is equipped with discharge ports and control valves for opening and closing these ports. This allows the discharge ports at the bottom of the first and second weighing hoppers to open and release material once a certain weight has been reached. Once the weight falls below a certain threshold, the discharge ports at the bottom of the first and second weighing hoppers close.

[0058] The weighing hopper, the first weighing hopper, and the second weighing hopper all include a hopper base with an opening at the bottom. A control valve is installed at the bottom opening of the hopper base. The hopper base is connected to a support base via a tension / compression sensor, facilitating weight monitoring.

[0059] When using this device, plastic products are placed in the first crusher 11 of the plastic product processing channel 1 for crushing and then transferred to the first hopper 13 for collection; cardboard boxes are placed in the second crusher 21 of the cardboard box product processing channel 2 for crushing and then transferred to the second hopper 23 for collection.

[0060] When compressing the plastic product, the control valve at the bottom of the first hopper 13 opens. When the weighing hopper senses the set maximum weight value, the control valve at the bottom of the first hopper 13 closes, and the valve at the bottom of the weighing hopper opens. When the weighing hopper senses the set minimum weight value, the valve at the bottom of the weighing hopper closes. The material is then fed into the compression assembly 4 for pressing into blocks. When the compression assembly compresses the plastic product, the left compression mechanism moves to the right to the compression position, the right compression mechanism moves to the left to the compression position, and the upper compression mechanism moves downward to the compression position. The front side plate 41, rear side plate 42, left slide plate, right slide plate, and upper pressure plate are heated to the set temperature and held under pressure for the set time, such as 1 minute, to complete the compression. After compression, the upper compression mechanism moves upward to the upper limit position, the left slide plate slides to the right limit position, and the right slide plate slides to the right sliding position. The pressed block is then moved out of the area between the front and rear side plates.

[0061] When compressing cardboard products, the control valve at the bottom of the second hopper 23 opens. When the weighing hopper senses the set maximum weight value, the control valve at the bottom of the second hopper 23 closes, and the valve at the bottom of the weighing hopper opens. When the weighing hopper senses the set minimum weight value, the valve at the bottom of the weighing hopper closes. The material is then fed into the compression assembly 4 for pressing. When the compression assembly compresses the cardboard products, the left compression mechanism moves to the right to the compression position, the right compression mechanism moves to the left to the compression position, and the upper compression mechanism moves downwards to the compression position. The front side plate 41, rear side plate 42, left slide plate, right slide plate, and upper pressure plate are heated to the set temperature and held under pressure for a set time, such as 1 minute. The spray mechanism is activated for a set time, such as 15 seconds, and then held under pressure for the set time, such as 1 minute, completing the compression. After compression, the upper compression mechanism moves upwards to the upper limit position, the left slide plate slides to the right limit position, and the right slide plate slides to the right sliding position. The pressed product is then moved out of the area between the front and rear side plates.

[0062] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
