Description

Technical Field

[0001] This invention belongs to the field of solid waste treatment technology, and more specifically, relates to a digital treatment device for industrial solid waste. Background Technology

[0002] With the rapid development of industrial manufacturing, the amount of industrial solid waste generated continues to grow. Its resource recycling and harmless disposal have become key links in promoting the development of a circular economy and reducing environmental burden. In this process, the digital sorting of industrial solid waste is the core process for achieving efficient recycling.

[0003] Existing digital processing devices for industrial solid waste generally use a planar conveyor belt structure for their transmission sections. Under this traditional structure, industrial solid waste is easily dispersed to the edges and corners of the conveyor belt or arranged irregularly during transmission due to its own inertia, mutual collisions, and differences in shape. This is especially true for waste that is slightly sticky on the surface, irregular in shape (such as flakes or strips), or lightweight, which is more likely to adhere to the side wall of the conveyor belt, making it difficult for it to naturally converge into the preset grabbing area. This dispersed state of waste directly causes the grabbing section to frequently adjust its motion parameters after the digital identification system completes data acquisition and positioning. For example, the rotating grabbing bracket needs to constantly change its rotation angle, and the telescopic robotic arm needs to adjust its extension distance in real time to adapt to the random and non-concentrated position of the waste. This not only greatly increases the complexity of the control logic and prolongs the cycle of a single grabbing, but also seriously restricts the efficiency of the entire sorting and processing process. In view of the above problems, a digital processing device for industrial solid waste is proposed here. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an industrial solid waste digital treatment device that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A digital treatment device for industrial solid waste includes a transmission unit, a gripping unit, a digital identification system, and a collection box. The digital identification system collects waste information on the transmission unit and transmits it to a control host. The control host drives the gripping unit to grab the waste. The transmission unit includes a conveyor belt and a limiting plate. A diversion hole communicating with the inner cavity of the limiting plate is provided on the groove surface of the limiting plate. When the conveyor belt passes the limiting plate, both sides of the conveyor belt flip upward. The gripping unit includes an annular mounting bracket with multiple gripping arms. Gripping heads are detachably connected to the gripping arms. When the gripping arms are working, they generate airflow that blows onto the upward-flipping conveyor belt, causing the conveyor belt to vibrate. Combined with gravity, this drives the waste to move to the middle position of the conveyor belt. The annular mounting bracket rotates to replace the gripping heads, grabs the waste in the middle of the conveyor belt, and rotates again to send the waste into the collection box.

[0006] In a preferred embodiment of the present invention, the transmission unit further includes a first mounting frame, both ends of which are rotatably mounted with transmission rollers, the transmission belt is rotatably mounted on the transmission rollers, the limiting plate is fixedly mounted on the first mounting frame, and a first motor is fixedly mounted on the side wall of the first mounting frame, the output end of the first motor being fixedly connected to the transmission rollers.

[0007] As a preferred embodiment of the present invention: a limiting groove is provided on the limiting plate, and a limiting strip is fixedly installed in the middle of the inner ring side of the conveyor belt, and the limiting strip is slidably installed in the limiting groove.

[0008] As a preferred embodiment of the present invention, it further includes a second mounting bracket, wherein a connecting block is fixedly mounted on the side wall of the first mounting bracket, and the connecting block is fixedly connected to the second mounting bracket.

[0009] In a preferred embodiment of the present invention, the gripping part further includes a mounting column fixedly mounted on a second mounting frame, a connecting arm rotatably mounted on the mounting column, a ring mounting bracket fixedly mounted on the connecting arm, a second motor fixedly mounted on the second mounting frame, and the second motor and the connecting arm being connected by a pulley group for transmission.

[0010] In a preferred embodiment of the present invention: the gripping arm includes a piston cylinder fixedly mounted on an annular mounting bracket and an electromagnet fixedly mounted on a mounting column. A slide rod is slidably mounted on the piston cylinder. A connecting plate connected to the gripping head is fixedly mounted at the bottom of the slide rod. A permanent magnet is fixedly mounted at the top of the slide rod. A piston plate is fixedly mounted on the slide rod. An air inlet is provided on the piston plate. A sealing gasket is fixedly mounted on the slide rod. The top of the sealing gasket is in contact with the piston plate. A spring is sleeved on the slide rod. The two ends of the spring abut against the sealing gasket and the piston cylinder, respectively. A limit rod is slidably mounted on the annular mounting bracket. The limit rod is fixedly connected to the slide rod.

[0011] As a preferred embodiment of the present invention: the electromagnet is provided with five magnetic surfaces, wherein the included angle between two adjacent magnetic surfaces is 135°, and the middle magnetic surface is parallel to the horizontal plane.

[0012] As a preferred embodiment of the present invention: a gas-gathering pipe is fixedly installed at the exhaust end of the piston cylinder, an exhaust hole connected to the gas-gathering pipe is provided on the connecting arm, a vent hole communicating with the exhaust hole is provided on the mounting column, a rotary joint communicating with the vent hole is fixedly installed on the mounting column, an exhaust pipe is fixedly installed at the output end of the rotary joint, and the exhaust pipe is connected to the inner cavity of the limiting plate.

[0013] As a preferred embodiment of the present invention: the collection box is provided with multiple slots, which are arranged in a stepped manner. By controlling the extension distance of the sliding rod, the grabbed waste can be placed into the corresponding slot.

[0014] As a preferred embodiment of the present invention: the digital recognition system includes a grating fixedly mounted on a second mounting bracket, and a visual camera is fixedly mounted on the side wall of the grating.

[0015] Beneficial effects: This invention utilizes the upward bending of the conveyor belt on both sides to initially gather edge waste towards the center under gravity. Combined with the airflow generated by the gripping unit during operation, this airflow blows onto the inclined belt wall, causing it to vibrate and further detach the waste from the belt wall, allowing it to roll into the central area. This achieves precise centering of waste during transport. This process ensures that all waste to be gripped is located in the fixed central area of ​​the conveyor belt, allowing the annular mounting bracket to simply rotate at a preset fixed angle to complete the replacement and precise alignment of the gripping head. There is no need for frequent adjustments to the rotation stroke due to waste position deviations. This significantly simplifies the control logic, improves gripping efficiency, reduces frequent speed and direction changes in the gripping unit, and lowers the probability of missed or misaligned gripping. Furthermore, the functional reuse of airflow eliminates the need for an additional calibration power source, controlling costs while ensuring gripping stability and equipment lifespan, and improving the stability, accuracy, and efficiency of waste gripping and sorting.

[0016] This invention utilizes the airflow buffered by the gripping section to drive the vibration of the conveyor belt, thereby creating an active peeling effect. Combined with the inclined guidance of the U-shaped conveyor belt, it drives waste that is slightly adhered to the surface, has an irregular shape (such as sheet-like or strip-like), or is easily attached to the conveyor belt wall to move towards the middle of the conveyor belt, reducing the positioning failure problem caused by the special shape of the waste.

[0017] In this invention, the combination of airflow vibration and gravity centering is a non-contact and low-impact centering method. Compared with the rigid correction structures such as mechanical feeding plates and side push blocks used in traditional devices, it can avoid the waste from being squeezed, scratched or deformed by collision, making it easier to recycle recyclable solid waste (such as plastic parts, glass products, etc.) that needs to maintain its integrity, thereby improving the value of downstream resource utilization.

[0018] In this invention, after the waste is accurately centered, the gripping head can stably grip the waste, avoiding the waste from falling or tilting during the transfer process due to the gripping position deviation, ensuring that it can accurately fall into the corresponding stepped bin, reducing the error rate of waste classification and improving the sorting purity.

[0019] In this invention, the airflow buffer mechanism of the gripping part not only protects the gripping head and the waste, but also absorbs the impact force generated by the movement of the sliding rod, reducing the noise generated by mechanical collision; at the same time, the conveyor belt achieves smooth centering through the limiting structure and airflow assistance, avoiding conveyor belt jamming and abnormal noise caused by waste deviation, thus reducing the environmental noise and equipment vibration during the operation of the device as a whole.

[0020] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] Example: Refer to Figures 1-12 A digital processing device for industrial solid waste includes a transmission unit 1, a gripping unit, a digital identification system 6, and a collection box 7. The digital identification system 6 collects waste information on the transmission unit 1 and transmits it to the control host. The control host drives the gripping unit to grip the waste.

[0025] Reference Figure 1 , Figures 3-7 The transmission unit 1 includes a first mounting frame 11, with transmission rollers 12 rotatably mounted on both ends of the first mounting frame 11. A transmission belt 13 is rotatably mounted on the two transmission rollers 12. A first motor 14 is fixedly mounted on the side wall of the first mounting frame 11, and the output end of the first motor 14 is fixedly connected to the transmission rollers 12.

[0026] When in use, the first motor 14 is started, which drives the transmission roller 12 to rotate, and the transmission roller 12 drives the transmission belt 13 to rotate, thereby transporting the waste that falls onto the transmission belt 13.

[0027] A limiting plate 15 is fixedly installed on the first mounting bracket 11. The limiting plate 15 has a U-shaped cross-section and the groove surface of the limiting plate 15 faces upward. A diversion hole 16 communicating with the inner cavity of the limiting plate 15 is provided on the groove surface of the limiting plate 15. A limiting groove 17 is provided on the limiting plate 15. A limiting strip 131 is fixedly installed in the middle of the inner ring side of the conveyor belt 13. The limiting strip 131 is slidably installed in the limiting groove 17.

[0028] Both the limiting groove 17 and the limiting strip 131 have T-shaped cross sections.

[0029] When the conveyor belt 13 passes the limiting plate 15, the inner side of the conveyor belt 13 slides against the limiting plate 15 with the cooperation of the limiting groove 17 and the limiting strip 131. Under the restriction of the arc-shaped wall of the limiting plate 15, the two sides of the conveyor belt 13 flip upward. Therefore, when passing the limiting plate 15, the cross-section of the conveyor belt 13 is U-shaped. The waste located on both sides of the conveyor belt 13 rolls down to the middle of the conveyor belt 13 under the action of gravity. Then, the corresponding information is identified by the digital identification system 6 (when processing different wastes, the corresponding identification system can be selected, such as color identification, material identification, size identification, etc.). Then, the grabbing part grabs and sends it into the collection box 7.

[0030] Reference Figure 1 , Figure 6 It also includes a second mounting bracket 2, and a connecting block 18 is fixedly installed on the side wall of the first mounting bracket 11, the connecting block 18 being fixedly connected to the second mounting bracket 2.

[0031] Reference Figures 1-3 and Figure 8 The gripping part includes a mounting column 21 fixedly mounted on the second mounting frame 2. A connecting arm 22 is rotatably mounted on the mounting column 21. An annular mounting bracket 23 is fixedly mounted on the connecting arm 22. The annular mounting bracket 23 is provided with multiple sets of gripping arms 3 (preferably 8 sets in this embodiment). A gripping head 35 is detachably connected to the gripping arm 3 (the gripping head 35 is any one of a vacuum suction cup, an electromagnet suction cup 24, or a pneumatic gripper, and the appropriate gripping head 35 can be selected according to the material of the waste being processed). The second mounting frame 2 is provided with a driving part 4 for driving the annular mounting bracket 23 to rotate.

[0032] Reference Figure 2 and Figure 9The drive unit 4 includes a second motor 41 fixedly mounted on the second mounting bracket 2. The second motor 41 is connected to the connecting arm 22 via a pulley set 42.

[0033] When in use, the second motor 41 is started, and the second motor 41 drives the connecting arm 22 to rotate on the mounting column 21 through the pulley group 42.

[0034] Reference Figure 8 , Figure 9 and Figure 11 The gripping arm 3 includes a piston cylinder 31 fixedly mounted on an annular mounting bracket 23 and an electromagnet 24 fixedly mounted on a mounting column 21. A slide rod 32 is slidably mounted on the piston cylinder 31. A connecting plate 34 connected to the gripping head 35 is fixedly mounted at the bottom of the slide rod 32. A permanent magnet 37 is fixedly mounted at the top of the slide rod 32. A piston plate 5 is fixedly mounted on the slide rod 32. An air inlet 51 is provided on the piston plate 5. A sealing gasket 52 is fixedly mounted on the slide rod 32. The top of the sealing gasket 52 is in contact with the piston plate 5. A spring 33 is sleeved on the slide rod 32. The two ends of the spring 33 abut against the sealing gasket 52 and the piston cylinder 31, respectively. A limit rod 36 is slidably mounted on the annular mounting bracket 23. The limit rod 36 is fixedly connected to the slide rod 32.

[0035] In this process, the top of the spring 33 only abuts against the inner ring of the sealing gasket 52. When the electromagnet 24 is energized and generates magnetic force, the electromagnet 24 and the permanent magnet 37 generate a repulsive force. The permanent magnet 37 drives the slide rod 32 to slide towards one end of the gripping head 35. During this process, the spring 33 is compressed. In addition, the air inside the piston cylinder 31 is compressed. Therefore, the pressure inside the piston cylinder 31 is greater than the external pressure. Under the action of the pressure difference, the sealing gasket 52 and the piston plate 5 are tightly attached to each other, sealing the air inlet 51. A one-way valve for exhausting gas is also provided at the exhaust end of the piston cylinder 31. The gas inside the piston cylinder 31 is discharged through the one-way valve after being compressed.

[0036] Reference Figure 8 The electromagnet 24 is provided with five magnetic surfaces (a magnetic surface is a surface that can generate magnetic force after the electromagnet 24 is energized). The included angle between two adjacent magnetic surfaces is 135°, and the middle magnetic surface is parallel to the horizontal plane. For ease of description, the middle magnetic surface is called the material picking surface, and the magnetic surfaces on both sides are called the material discharging surface.

[0037] When the material-grabbing surface generates a repulsive force, the slide bar 32 drives the gripping head 35 to move vertically downward to grab the waste. After grabbing the waste, the material-grabbing surface is de-energized, the magnetic force is eliminated, and then the compressed spring 33 is reset, thereby driving the slide bar 32 to move towards the mounting column 21. At this time, the air pressure inside the piston cylinder 31 is lower than that outside the piston cylinder 31. Under the pressure difference, the external air passes through the air inlet 51, pushes open the sealing gasket 52, and enters the piston cylinder 31.

[0038] Reference Figure 2 , Figure 3 and Figure 12 The piston cylinder 31 has a gas-gathering pipe 53 fixedly installed at its exhaust end. The connecting arm 22 is provided with an exhaust hole 54 connected to the gas-gathering pipe 53. The mounting column 21 is provided with a vent hole 55 communicating with the exhaust hole 54. The mounting column 21 is fixedly installed with a rotary joint 56 communicating with the vent hole 55. The output end of the rotary joint 56 is fixedly installed with an exhaust pipe 57. The exhaust pipe 57 is connected to the inner cavity of the limiting plate 15.

[0039] During use, the sliding bar 32 drives the gas flow as it slides back and forth. On the one hand, the damping generated by the gas flow buffers the extension and resetting of the sliding bar 32, preventing the gripping head 35 from being damaged by rapid impact. It also prevents fragile and easily deformable waste from being damaged or deviated from its proper position, ensuring the integrity of the gripping process. On the other hand, the discharged gas is sent into the limiting plate 15 and discharged through the diversion hole 16. The discharged gas blows towards the upwardly bent belt wall of the conveyor belt 13, causing the inclined belt wall of the conveyor belt 13 to vibrate slightly, causing the waste on the inclined belt wall of the conveyor belt 13 to detach from the belt wall and finally roll down to the middle area of ​​the conveyor belt 13, preventing the position of the waste from deviating from the gripping point of the gripping head 35 and improving the gripping accuracy.

[0040] Reference Figure 2 and Figure 10 The digital identification system 6 includes a grating 61 fixedly installed on the second mounting bracket 2, and a visual camera 62 is fixedly installed on the side wall of the grating 61.

[0041] The grating 61 forms an optical mesh along the width of the conveyor belt 13. By blocking the position and duration of the optical axis, it can digitally output the three-dimensional spatial coordinates of the waste on the X-axis (width direction of the conveyor belt 13) and Y-axis (transmission direction), as well as the basic dimensions such as length and width. It can also send digital trigger signals to activate subsequent equipment. After the vision camera 62 captures high-definition images of the waste, it converts the color, texture, shape and other features into digital information such as RGB values ​​and texture parameters through algorithms. The two types of data are transmitted to the control host in real time. After digital fusion and analysis, structured instructions such as waste type code, gripper head 35 model and collection box 7 number are generated. This drives the ring mounting bracket 23 of the gripper to rotate at a digital angle and the slide bar 32 to extend at a digital distance. At the same time, all collected data such as waste location, type and sorting results are digitally stored, providing accurate basis and traceable management for the sorting process.

[0042] Reference Figure 1 and Figure 2 The collection box 7 is equipped with multiple slots arranged in a stepped manner. By controlling the extension distance of the slide bar 32, the grabbed waste can be placed into the corresponding slot.

[0043] In summary, the upward bending of the conveyor belt 13 on both sides causes the edge waste to initially gather towards the center under gravity. Combined with the airflow generated by the gripping unit during operation, which blows the airflow onto the inclined belt wall of the conveyor belt 13 and causes it to vibrate, the waste on the belt wall is further dislodged and rolled into the central area, achieving precise centering of waste during the transmission process. This process ensures that all waste to be gripped is in the fixed central area of ​​the conveyor belt 13, so that the annular mounting bracket 23 only needs to rotate at a preset fixed angle to complete the replacement and precise alignment of the gripping head 35. There is no need to frequently adjust the rotation stroke due to waste position deviation. This not only greatly simplifies the control logic and improves gripping efficiency, but also reduces the frequent speed and direction changes of the gripping unit, reducing the probability of missing or misaligned gripping. At the same time, the functional reuse of airflow eliminates the need for an additional calibration power source, controlling costs while ensuring gripping stability and equipment lifespan, and improving the stability, gripping accuracy, and gripping efficiency of waste gripping and sorting.

[0044] For waste that is slightly sticky on the surface, irregular in shape (such as flakes or strips), or heavy enough to easily adhere to the wall of the conveyor belt 13, relying solely on gravity for centering can easily result in residue. However, the vibration of the conveyor belt 13 driven by airflow can create an active peeling effect. Combined with the inclined guidance of the U-shaped conveyor belt 13, it can cover the centering needs of waste with more different shapes and reduce the positioning failure problem caused by the special shape of the waste.

[0045] The combination of airflow vibration and gravity centering is a non-contact and low-impact centering method. Compared with the rigid correction structures such as mechanical feeding plates and side push blocks used in traditional devices, it can avoid the waste from being squeezed, scratched or deformed by collision. It is convenient to recycle recyclable solid waste (such as plastic parts, glass products, etc.) that needs to maintain its integrity, thereby improving the value of downstream resource utilization.

[0046] After the waste is accurately centered, the gripper head 35 can stably grip the waste, avoiding the waste from falling or tilting during the transfer process due to the gripping position deviation. This ensures that the waste can fall accurately into the corresponding stepped bin, reducing the error rate of waste classification and improving the sorting purity.

[0047] The airflow buffer mechanism of the gripping section not only protects the gripping head 35 and the waste, but also absorbs the impact force generated by the movement of the slide bar 32, reducing the noise generated by mechanical collisions. At the same time, the conveyor belt 13 achieves smooth centering through the limiting structure and airflow assistance, avoiding the conveyor belt 13 from jamming and abnormal noise caused by waste deviation, thus reducing the environmental noise and equipment vibration during the operation of the device.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
