Description

Technical Field

[0001] This invention relates to the field of tableware recycling technology, specifically to a biodegradable tableware production waste recycling device. Background Technology

[0002] Biodegradable tableware has the value of being recycled and reused. If it is directly piled up and discarded, not only will the scattered waste occupy space, but it will also cause a serious waste of raw material resources. Furthermore, it is easy to deteriorate due to moisture and contamination, affecting subsequent recycling.

[0003] Some tableware has cavities or grooves, especially lunch boxes, which easily trap and accumulate residual oil and soup. Once the oil has solidified, it adheres strongly and cannot be effectively removed by conventional cleaning processes. At the same time, cleaning costs are high and the process is difficult. During the recycling process, the oil residue in the tank cavity is prone to seepage and flow when the items are mixed together, which can contaminate clean and lightly soiled tableware. As a result, a large number of tableware that are eligible for recycling are contaminated with oil and cannot be recycled normally. At the same time, the rampant spread of oil will also make the storage space dirty and increase the burden of subsequent cleaning and maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide a biodegradable tableware production waste recycling device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides a biodegradable tableware production waste recycling device, including a recycling box and a separation chamber opened in the recycling box. The recycling box has a feeding port that communicates with the separation chamber. The recycling box has two chambers. The separation chamber has a recycling chamber inlet and a processing chamber inlet that are spaced apart. The recycling chamber inlet and the processing chamber inlet have a height difference and are respectively connected to the two chambers through the recycling chamber inlet and the processing chamber inlet. The separation chamber is equipped with a separator, and a driving mechanism is provided below the separator for driving the separator to slide along the height direction of the separation chamber. In the initial state, the separator is lower than the inlet of the recovery chamber and the inlet of the processing chamber. The separator includes at least a number of support plates, which are arranged circumferentially with the axis of the separation chamber as the origin, and gaps are left between the support plates for liquid to pass through. The separation chamber is equipped with a detection mechanism, which drives the separator to rotate according to the arrangement of tableware on the support plate, so that contaminated and uncontaminated tableware correspond to the inlet of the recycling chamber and the inlet of the processing chamber, respectively.

[0006] Furthermore, the separator also includes a support rod, the axis of which overlaps with the separation chamber, multiple support plates are arranged at intervals along the outer peripheral wall of the support rod, and a drive mechanism is connected to the support rod to drive the support rod to lift or rotate. The support plate has an arc surface, with the lower end of the arc surface extending to the bottom of the support plate away from the support rod, and the upper end extending to the connection between the top of the support plate and the support rod, so that the support plate is arranged in a fan shape, with the top of the support plate being close to the top of the support rod.

The bottom end of the support plate is hinged to the inner wall of the strip-shaped opening. The vertical channel is equipped with a trigger, which includes at least a plurality of push rods extending into the strip opening. The push rods can slide back and forth along the strip opening to push the support plate to swing around the hinge point as the origin.

[0008] Furthermore, a groove is provided on one side of the support plate, and one end of the top rod extends into the groove and is slidably connected to the groove. A shaft is also provided at the hinge of the support plate and the strip opening. Both ends of the shaft are connected to the inner wall of the strip opening, and the support plate is rotatably connected to the outer wall of the shaft. A torsion spring is sleeved on the shaft, with one end of the torsion spring connected to the support plate and the other end connected to the outer wall of the shaft.

[0009] Furthermore, the bottom opening of the support rod is configured to communicate with the vertical channel. The trigger also includes a mounting rod, which is located in the vertical channel. Multiple strip grooves are formed on the outer peripheral wall of the mounting rod, and the end of the strip groove away from the slide groove extends into the strip groove. The mounting rod has a through channel, and a lead screw is installed in the through channel. The top end of the lead screw is rotatably connected to the inner top wall of the vertical channel. A sliding ring is threaded onto the outer wall of the lead screw, and the outer wall of the sliding ring is slidably connected to the inner wall of the through channel. A collar is fitted onto the outer wall of the mounting rod, and multiple top rods are connected to the collar. At least two connecting rods are connected between the sliding ring and the collar. The mounting rod has a through slot for the connecting rods to pass through, and the through slot communicates with the through channel.

[0010] Furthermore, the top rod has a through-hole and is fitted onto the collar through the through-hole. There is a gap between the outer wall of the collar and the inner wall of the through-hole. A first magnetic surface is installed on one end of the top rod close to the strip groove, and a second magnetic surface is installed on the side of the strip groove corresponding to the top rod. The first magnetic surface and the second magnetic surface are magnetically attracted to each other.

[0011] Furthermore, a tray is installed at the bottom of the support rod, and multiple partitions corresponding vertically to the support plate are installed on the top of the tray. A flow channel is formed between adjacent partitions. The tray is located below the support plate, and a support pedestal is installed on the top of the tray. The support pedestal extends from the bottom of the support rod into the vertical channel. The bottom of the mounting rod is connected to the top of the support pedestal, and the bottom of the lead screw is rotatably connected to the top of the support pedestal. A driving component is provided inside the tray, and the driving end of the driving component is connected to the bottom of the lead screw.

[0012] Furthermore, the drive mechanism includes a threaded rod, the top end of which is connected to the bottom of the tray. A base is installed on the inner bottom wall of the separation chamber. A first electric push rod and a second electric push rod are respectively installed on the top of the base. A bracket is rotatably connected to the bottom of the threaded rod. The telescopic end of the first electric push rod is connected to the inner top wall of the bracket. The outer wall of the threaded rod is threaded with a threaded sleeve, and a fixing plate is installed on the outer wall of the threaded sleeve. The telescopic end of the second electric push rod is connected to the bottom of the fixing plate.

[0013] Furthermore, an inclined plate is installed inside the separation chamber, with one end of the inclined plate connected to the delivery port and the other end extending inclinedly towards the top of the support rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, after the tableware is put into the separation chamber, it falls onto the support plate. The support plate prevents the tableware from falling. Residual oil stains between the tableware can naturally seep through the gaps between multiple support plates. The driving mechanism can drive the support plate to swing back and forth slightly to accelerate the discharge of oil stains. Clean and lightly soiled tableware can be directly collected and recycled, while heavily soiled tableware can be collected separately for easy subsequent unified processing. Through physical partitioning and isolation, cross-contamination can be effectively avoided and the tableware recycling rate can be improved.

[0015] 2. In this invention, after the tableware falls onto the support plate, it can naturally slide and disperse along the arc surface, avoiding accumulation in the middle position, so that the tableware is evenly distributed in the area around the support plate. The whole adopts a rounded transition design without sharp edges and corners, which effectively prevents the tableware from getting stuck and avoids collisions that cause damage, thus improving the stability of the feeding and sorting process.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a technical solution: See Figures 1-15 As shown, a biodegradable tableware production waste recycling device includes a recycling box 1 and a separation chamber 21 opened in the recycling box 1. The recycling box 1 has a feeding port 2 that communicates with the separation chamber 21. The recycling box 1 has two chambers. The separation chamber 21 has a recycling chamber inlet 23 and a processing chamber inlet 24 that are spaced apart. The recycling chamber inlet 23 and the processing chamber inlet 24 have a height difference and are respectively connected to the two chambers through the recycling chamber inlet 23 and the processing chamber inlet 24. The separation chamber 21 is provided with a separator, and a driving mechanism is provided below the separator for driving the separator to slide along the height direction of the separation chamber 21. In the initial state, the separator is lower than the inlet 23 of the recovery chamber and the inlet 24 of the processing chamber. The separator includes at least a plurality of support plates 3, which are arranged circumferentially with the axis of the separation chamber 21 as the origin, and gaps are left between the plurality of support plates 3 for liquid to pass through. The separation chamber 21 is equipped with a detection mechanism, which drives the separator to rotate according to the arrangement of tableware on the support plate 3, so that contaminated and uncontaminated tableware correspond to the recycling chamber inlet 23 and the processing chamber inlet 24 respectively.

[0020] First look Figure 2 The tableware is put into the separation chamber 21 from the feeding port 2. In the initial state, when viewed along the height direction of the separation chamber 21, the height of the support plate 3 is lower than the inlet 23 of the recycling chamber and the inlet 24 of the processing chamber. The inlet 23 of the recycling chamber and the inlet 24 of the processing chamber serve as the inlets of two chambers respectively. The chamber corresponding to the inlet 23 of the recycling chamber is the recycling chamber, and the chamber corresponding to the inlet 24 of the processing chamber is the processing chamber. Some of the lunch boxes with recessed spaces contain oil stains. After these utensils enter the separation chamber 21, they fall onto multiple support plates 3. The multiple support plates 3 shield the utensils to prevent them from falling further. After the utensils collide with the support plates 3, they are scattered on the multiple support plates 3. Then, the oil stains in some of the lunch boxes with oil stains flow down through the gaps between the support plates 3. To help the food container drain the oil, the drive mechanism can drive the support plate 3 to rotate back and forth slightly, causing the tableware to shake. After the oil spills out, the tableware scattered on the multiple support plates 3 is detected, and the drive mechanism drives the support plate 3 to rotate. The tableware contaminated with oil is aligned with the processing chamber inlet 24, while the tableware that is not contaminated or has a small degree of contamination is aligned with the recycling chamber inlet 23. The height of the processing chamber inlet 24 is lower than that of the recycling chamber inlet 23. After the drive mechanism drives the support plate 3 to rotate to a suitable angle, it drives the support plate 3 to move upward. The support plate 3 first reaches the processing chamber inlet 24. Some of the more heavily soiled lunch boxes corresponding to the processing chamber inlet 24 directly pass through the processing chamber inlet 24 and fall into the processing chamber. Then the support plate 3 continues to move upward. After reaching the recycling chamber inlet 23, the uncontaminated and less contaminated lunch boxes pass through the recycling chamber inlet 23 and fall into the recycling chamber. Since tableware is distributed around the support plate 3, after the support plate 3 reaches the position of the processing chamber inlet 24 and the recycling chamber inlet 23, the support plate 3 will still rotate and adjust the angle so that all the tableware can fall into the recycling chamber inlet 23 or the processing chamber inlet 24 without being left behind. The recovery chamber and the processing chamber are independent and sealed separate chambers, which are fixed on both sides of the separation chamber 21. The inlet 23 of the recovery chamber and the inlet 24 of the processing chamber are both through openings with the opening size adapted to the shape of the tableware. The gap width between adjacent support plates 3 is smaller than the minimum external size of conventional tableware, allowing only liquid impurities such as oil and sewage to seep downwards to prevent the tableware from falling. The detection mechanism is a combination of a high-definition visual inspection module and an oil stain sensor, which is fixedly installed on the upper part of the inner side wall of the separation chamber 21, directly facing the bearing area of ​​the support plate 3. The detection mechanism is electrically connected to the main control unit of the device to collect data on the surface stains and oil stains of the tableware in real time. In the initial state, the drive mechanism is locked and the separator is stationary, ensuring that the tableware falls stably on the bearing surface of the support plate 3. The surface of the support plate 3 is treated with an anti-stick coating to reduce oil adhesion and accelerate the rapid collection and leakage of liquid oil. The small-amplitude alternating rotation is a limited angle reciprocating rotation, with the rotation angle less than 30° to prevent tableware from tipping over and falling off. The oil leakage time is preset to a fixed time, and the detection agency will start identification and judgment after the time is reached. Height limit sensors are installed on the inner wall of the separation chamber 21, corresponding to the inlet 24 of the processing chamber and the inlet 23 of the recycling chamber, respectively. They provide real-time feedback on the lifting position of the support plate 3, enabling precise start and stop control. After a single lifting and sorting operation is completed, the separator is reset to the initial low position, ready for the next batch of tableware to be delivered. By utilizing the leakage gaps reserved between multiple support plates 3, oil pre-separation can be completed in advance before sorting and classification. This proactively discharges free oil that is easy to flow inside the tableware cavity, reducing the amount of oil adhering and weakening the solidification conditions of stubborn oil. Tableware that meets the conditions can be directly recycled, while heavily contaminated tableware can be destroyed or cleaned later depending on the situation, ensuring the recycling rate. At the same time, it isolates some tableware that does not need to be cleaned, reducing the workload and processing costs of subsequent cleaning.

[0021] See Figures 2-3 The separator also includes a support rod 4, which overlaps with the axis of the separation chamber 21. Multiple support plates 3 are arranged at intervals along the outer peripheral wall of the support rod 4. The drive mechanism is connected to the support rod 4 and is used to drive the support rod 4 to lift or rotate. The support plate 3 has an arc surface 31. The lower end of the arc surface 31 extends to the bottom of the support plate 3 away from the support rod 4, and the upper end extends to the connection between the top of the support plate 3 and the support rod 4, so that the support plate 3 is arranged in a fan shape, and the top of the support plate 3 is set close to the top of the support rod 4.

[0022] The support rod 4 is located in the middle between multiple support plates 3. The top of the arc surface 31 is close to the top of the support rod 4, and then the arc surface 31 forms an outward arched slope. Its bottom end is close to the inner wall of the separation cavity 21. After the tableware falls from the top onto the support plate 3, it will be dispersed in all directions along the arc surface 31 and will not gather at the top, helping the tableware to spread on multiple support plates 3, that is, around the support rod 4. The curved surface 31 has a smooth, rounded transition structure with no sharp edges, preventing tableware from getting stuck or broken.

[0023] See Figures 4-9 The support rod 4 has a vertical channel 42 inside, and the support rod 4 has multiple strip openings 41 with the same number as the support plate 3. The strip openings 41 are connected to the vertical channel 42. One side of the support plate 3 is inserted into the strip opening 41, and the bottom end of the support plate 3 is hinged to the inner wall of the strip opening 41. The vertical channel 42 is equipped with a trigger, which includes at least a plurality of push rods 7 extending into the strip opening 41. The push rods 7 can slide back and forth along the strip opening 41 to push the support plate 3 to swing around the hinge point. The strip opening 41 is a long rectangular groove with dimensions matching the shape of the insertion end of the support plate 3, and a margin for swinging movement is reserved.

[0024] First look Figure 5 Multiple strip-shaped openings 41 are evenly spaced along the length of the support rod 4. The left side and bottom of the support plate 3 are flat. The vertical surface of the left side of the support plate 3 is inserted into the strip-shaped openings 41. Then look... Figure 7 The intersection of the vertical surface on the left side of the support plate 3 and the horizontal surface at the bottom is the hinge point. The support plate 3 is hinged to the inner wall of the strip opening 41 through the hinge point, and the support plate 3 can swing with the hinge point as the origin. The hinge point is located within the strip opening 41 and close to the vertical channel 42. An elastic reset structure is provided at the hinge point to keep the support plate 3 in place. Figure 7 In this state, the vertical surface on the left side of the support plate 3 is located inside the strip opening 41, and the initial position of the push rod 7 is at the top of the vertical channel 42. When the support plate 3 reaches the area of ​​the processing chamber inlet 24 or the recovery chamber inlet 23, the push rod 7 is controlled to move downward along the vertical channel 42. Please see here. Figure 8 As the top rod 7 gradually moves down and approaches the shaft 32, the top rod 7 will abut against the left side of the support plate 3, causing the arc surface 31 on the support plate 3 to swing downward to the right, helping the tableware located on the arc surface 31 to be pushed into the processing chamber inlet 24 or the recycling chamber inlet 23 by the arc surface 31. When the top rod 7 moves up again, the elastic recovery structure will pull back the support plate 3, causing it to swing back to its initial position.

[0025] See Figures 9-12 A groove 33 is provided on one side of the support plate 3. One end of the top rod 7 extends into the groove 33 and is slidably connected to the groove 33. A shaft 32 is also provided at the hinge of the support plate 3 and the strip opening 41. Both ends of the shaft 32 are fixedly connected to the inner wall of the strip opening 41. The support plate 3 is rotatably connected to the outer wall of the shaft 32. A torsion spring is sleeved on the shaft 32. One end of the torsion spring is connected to the support plate 3, and the other end is fixedly connected to the outer wall of the shaft 32.

[0026] The position of the slide groove 33 is the vertical surface on the left side of the support plate 3, that is, the side inside the strip opening 41. When the push rod 7 moves, it slides along the slide groove 33, and at the same time, it abuts against and pushes the support plate 3 to swing. The shaft 32 is fixed inside the strip opening 41. When the support plate 3 swings, the lower left corner of the support plate 3 will rotate along the outer wall of the shaft 32, and at the same time, it will compress the torsion spring. When the push rod 7 moves upward and no longer resists the support plate 3, the torsion spring is responsible for pulling the support plate 3 back to the initial angle. The torsion spring is a circumferential force storage structure, which continuously provides reset torque under normal conditions. After the push rod 7 releases the pushing force, the torsion spring torque drives the support plate 3 to automatically rotate and reset.

[0027] See Figures 11-15 The bottom opening of the support rod 4 is connected to the vertical channel 42. The trigger also includes a mounting rod 71, which is located in the vertical channel 42. Multiple strip grooves 74 are provided on the outer peripheral wall of the mounting rod 71, and one end of the strip groove 74 away from the slide groove 33 extends into the strip groove 74. The mounting rod 71 has a through channel 711, and a lead screw 72 is installed in the through channel 711. The top end of the lead screw 72 is rotatably connected to the inner top wall of the vertical channel 42. A sliding ring 77 is threadedly connected to the outer wall of the lead screw 72. The outer wall of the sliding ring 77 is slidably connected to the inner wall of the through channel 711. A collar 73 is fitted on the outer wall of the mounting rod 71. Multiple top rods 7 are connected to the collar 73. At least two connecting rods 75 are fixedly connected between the sliding ring 77 and the collar 73. The mounting rod 71 has a through slot 76 for the connecting rods 75 to pass through. The slot 76 communicates with the through channel 711.

[0028] The drive screw 72 rotates alternately clockwise and counterclockwise, allowing the sliding ring 77 to slide up and down along the outer wall of the screw 72. The two ends of the connecting rod 75 are fixedly connected to the outer walls of the sliding ring 77 and the collar 73, respectively. The strip groove 76 is opened through the through channel 711 to provide space for the connecting rod 75 to slide. When the sliding ring 77 slides along the outer wall of the screw 72, it drives the collar 73 to slide together through the connecting rod 75. Then, the collar 73 drives multiple push rods 7 to move the push rods 7 up or down. When the push rod 7 moves, one end can slide along the strip groove 74 and the other end can slide along the sliding groove 33. Both ends of the push rod 7 have sliding support paths, making it more stable when moving.

[0029] See Figure 15 The push rod 7 has a through-hole 78, which is fitted onto the collar 73. There is a gap between the outer wall of the collar 73 and the inner wall of the through-hole 78. A first magnetic surface 79 is installed at one end of the push rod 7 close to the strip groove 74, and a second magnetic surface 710 is installed on the side of the strip groove 74 corresponding to the push rod 7. The first magnetic surface 79 and the second magnetic surface 710 are magnetically attracted to each other.

[0030] Please see Figure 15 According to the size of the cross-section of the inlet 23 of the recycling chamber, the opening 78 must be larger than this size. The first magnetic attraction surface 79 can be a magnet, while the second magnetic attraction surface 710 can be an electromagnet. Only when the corresponding second magnetic attraction surface 710 is energized can it attract the corresponding first magnetic attraction surface 79, so that the two are magnetically attracted and the push rod 7 is horizontal. When the support plate 3 reaches the position corresponding to the processing chamber inlet 24 or the recycling chamber inlet 23, the second magnetic attraction surface 710 in part of the area corresponding to the processing chamber inlet 24 or the recycling chamber inlet 23 is energized, and then the corresponding first magnetic attraction surface 79 is attracted, so that the push rod 7 is horizontal. Then, when the collar 73 moves, it can drive the push rod 7 to push the slide 33. The remaining unenergized second magnetic surface 710, the first magnetic surface 79 and the second magnetic surface 710 are not in a magnetic attraction state. When the collar 73 moves, the end of the push rod 7 away from the strip groove 74 will droop and not be horizontal. In this way, the push rod 7 cannot push the support plate 3 to swing when it moves. Therefore, the support plate 3 outside the range of the processing chamber inlet 24 or the recycling chamber inlet 23 does not need to swing, so as to prevent the support plate 3 from clamping the tableware when swinging. It is only necessary to make the support plate 3 within the range of the processing chamber inlet 24 or the recycling chamber inlet 23 swing and push the tableware. The electromagnet is electrically connected to the main control unit of the device, receives the zone control signals from the detection mechanism, and realizes fixed-point individual electromagnetic attraction.

[0031] See Figures 3-6 A tray 5 is fixedly installed at the bottom of the support rod 4. Multiple partitions 51 corresponding vertically to the support plate 3 are fixedly installed on the top of the tray 5. A guide channel 52 is formed between adjacent partitions 51. The tray 5 is located below the support plate 3. A support base 53 is fixedly installed on the top of the tray 5. The support base 53 extends from the bottom of the support rod 4 into the interior of the vertical channel 42. The bottom of the mounting rod 71 is fixedly connected to the top of the support base 53. The bottom of the lead screw 72 is rotatably connected to the top of the support base 53. A driving component is provided inside the tray 5. The driving end of the driving component is connected to the bottom of the lead screw 72.

[0032] The driving component can be a motor, which is fixed inside the tray 5. The driving end of the motor passes through the support base 53 and is fixedly connected to the bottom end of the lead screw 72 to drive the lead screw 72 to rotate. The mounting rod 71 is fixed to the top of the support base 53. The oil stains fall along the support plate 3 into the guide channel 52 and then flow down through the outer edge of the tray 5.

[0033] See Figure 3 The drive mechanism includes a threaded rod 6, the top end of which is fixedly connected to the bottom of the tray 5. A base 25 is fixedly installed on the inner bottom wall of the separation chamber 21. A first electric push rod 64 and a second electric push rod 65 are fixedly installed on the top of the base 25 respectively. A bracket 63 is rotatably connected to the bottom of the threaded rod 6. The telescopic end of the first electric push rod 64 is fixedly connected to the inner top wall of the bracket 63. The outer wall of the threaded rod 6 is threaded with a threaded sleeve 61, and a fixing plate 62 is fixedly installed on the outer wall of the threaded sleeve 61. The telescopic end of the second electric push rod 65 is fixedly connected to the bottom of the fixing plate 62.

[0034] The first electric push rod 64 is used to push the bracket 63 to move up or down, and then the bracket 63 drives the threaded rod 6 to move up or down, thereby realizing the lifting and lowering of the support plate 3. When only the support plate 3 needs to move up, the first electric push rod 64 and the second electric push rod 65 start synchronously. The first electric push rod 64 drives the bracket 63 to move up, and the second electric push rod 65 synchronously drives the threaded sleeve 61 and the fixed plate 62 to move up. When the support plate 3 needs to rotate, the first electric push rod 64 stops driving the threaded rod 6 to move up or down, and the second electric push rod 65 drives the threaded sleeve 61 to move up or down. Through the threaded engagement between the threaded sleeve 61 and the threaded rod 6, the threaded rod 6 rotates, which in turn drives the tray 5 to rotate the support rod 4 and the support plate 3. The synchronous and individual operation modes of the first electric push rod 64 and the second electric push rod 65 are switched and controlled by the main control program, realizing conflict-free switching between the lifting and rotating operation modes.

[0035] See Figure 2 An inclined plate 22 is fixedly installed inside the separation chamber 21. One end of the inclined plate 22 is connected to the delivery port 2, and the other end extends inclinedly towards the top of the support rod 4.

[0036] After the tableware is put into the inlet 2, it falls to the top of the support rod 4 along the guide slope of the inclined plate 22. Then the tableware spreads freely around the support rod 4 and is distributed on multiple support plates 3.
