Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of solid waste treatment, and particularly relates to an industrial solid waste digital processing device. BACKGROUND

[0002] With the rapid development of industrial manufacturing, the amount of industrial solid waste continues to grow, and its resource recycling and harmless disposal has become a key link to promote the development of circular economy and reduce environmental load. In this process, the digital sorting of industrial solid waste is the core process of efficient recycling.

[0003] The transmission part of the existing industrial solid waste digital processing device generally adopts a flat transmission belt structure. Under this traditional structure, industrial solid waste is easily dispersed to the edges and corners of the transmission belt or arranged irregularly during transmission due to factors such as inertia, mutual collision, and shape difference. Especially for those slightly sticky, irregularly shaped (such as sheet-shaped or strip-shaped) or light-weight wastes, they are more likely to adhere to the side wall of the transmission belt, making it difficult to naturally converge to the preset grabbing area. This dispersed state of waste directly causes the grabbing part to need to frequently adjust its motion parameters after the digital identification system completes data acquisition and positioning. For example, the rotating grabbing support needs to constantly change the rotation angle, and the telescopic mechanical arm needs to adjust the 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 period of single grabbing, but also seriously restricts the efficiency of the entire sorting process. In view of the above problems, an industrial solid waste digital processing device is proposed. SUMMARY

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0037] Embodiment: Refer to Figures 1-12 An industrial solid waste digital processing device, comprising a conveying part 1, a grabbing part, a digital identification system 6 and a collection box 7, the digital identification system 6 collects waste information on the conveying part 1 and transmits to a control host, the control host drives the grabbing part to grab the waste.

[0038] Referring to Figure 1 , Figures 3-7 , the transmission part 1 comprises a first mounting frame 11, both ends of the first mounting frame 11 are rotatably installed with transmission rollers 12, two transmission rollers 12 are rotatably installed with a transmission belt 13, a side wall of the first mounting frame 11 is fixedly installed with a first motor 14, and an output end of the first motor 14 is fixedly connected with the transmission roller 12.

[0039] In use, the first motor 14 is started to drive the transmission roller 12 to rotate, and the transmission roller 12 drives the transmission belt 13 to rotate, so as to transmit the waste falling on the transmission belt 13.

[0040] The first mounting frame 11 is fixedly installed with a limiting plate 15, the limiting plate 15 is U-shaped in cross section, the recessed surface of the limiting plate 15 faces upward, the recessed surface of the limiting plate 15 is provided with a shunt hole 16 communicating with the inner cavity of the limiting plate 15, the limiting plate 15 is provided with a limiting groove 17, the middle of the inner ring side of the transmission belt 13 is fixedly installed with a limiting strip 131, and the limiting strip 131 is slidably installed in the limiting groove 17.

[0041] The limiting groove 17 and the limiting strip 131 are both T-shaped in cross section.

[0042] When the transmission belt 13 passes through the limiting plate 15, the inner side of the transmission belt 13 slides against the limiting plate 15 under the cooperation of the limiting groove 17 and the limiting strip 131, and the two sides of the transmission belt 13 are turned upward under the limitation of the arc-shaped wall of the limiting plate 15, so that the cross section of the transmission belt 13 is U-shaped when passing through the limiting plate 15, and the waste on both sides of the transmission belt 13 rolls down to the middle of the transmission belt 13 under the action of gravity, then passes through the digital identification system 6 to identify the corresponding information (when different wastes are processed, the corresponding identification system can be selected, such as color identification, material identification, size identification, etc.), and then is grabbed by the grabbing part and sent into the collection box 7.

[0043] Referring to Figure 1 , Figure 6 , the transmission part 1 further comprises a second mounting frame 2, a connecting block 18 is fixedly installed on the side wall of the first mounting frame 11, and the connecting block 18 is fixedly connected with the second mounting frame 2.

[0044] Referring to Figures 1-3 and Figure 8The grabbing part comprises a mounting column 21 fixedly installed on the second mounting frame 2, a connecting arm 22 rotatably installed on the mounting column 21, an annular mounting bracket 23 fixedly installed on the connecting arm 22, a plurality of groups of grabbing arms 3 (in the embodiment, preferably 8 groups of grabbing arms 3) arranged on the annular mounting bracket 23, and a grabbing head 35 (the grabbing head 35 is any one of a vacuum chuck, an electromagnet 24 chuck, and a pneumatic clamping jaw, and the corresponding grabbing head 35 can be selected according to the material of the waste to be handled) detachably connected to the grabbing arm 3. The second mounting frame 2 is provided with a driving part 4 for driving the annular mounting bracket 23 to rotate.

[0045] With reference to Figure 2 and Figure 9 , the driving part 4 comprises a second motor 41 fixedly installed on the second mounting frame 2, and the second motor 41 is in transmission connection with the connecting arm 22 through a belt wheel set 42.

[0046] 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 belt wheel set 42.

[0047] With reference to Figure 8 、 Figure 9 and Figure 11 , the grabbing arm 3 comprises a piston cylinder 31 fixedly installed on the annular mounting bracket 23 and the electromagnet 24 fixedly installed on the mounting column 21. The grabbing arm 3 further comprises a sliding rod 32 slidably installed on the piston cylinder 31, a connecting plate 34 fixedly installed at the bottom of the sliding rod 32 and connected to the grabbing head 35, a permanent magnet 37 fixedly installed at the top of the sliding rod 32, a piston plate 5 fixedly installed on the sliding rod 32, an air inlet hole 51 arranged on the piston plate 5, a sealing gasket 52 fixedly installed on the sliding rod 32 and abutting against the piston plate 5, and a spring 33 sleeved on the sliding rod 32 and abutting against the sealing gasket 52 and the piston cylinder 31 at two ends thereof. The annular mounting bracket 23 is slidably installed with a limiting rod 36 fixedly connected with the sliding rod 32.

[0048] In the embodiment, the top end of the spring 33 only abuts against the inner ring of the sealing gasket 52. When the electromagnet 24 generates a magnetic force after being powered, the electromagnet 24 generates a repulsive force with the permanent magnet 37, the permanent magnet 37 drives the sliding rod 32 to slide towards one end of the grabbing head 35, in the process, the spring 33 is compressed. In addition, the air in the piston cylinder 31 is compressed, so that the pressure in the piston cylinder 31 is greater than the external pressure. Under the action of the pressure difference, the sealing gasket 52 is tightly abutted against the piston plate 5, and the air inlet hole 51 is sealed. A one-way valve for discharging air outward is further arranged at the exhaust end of the piston cylinder 31, and the gas in the piston cylinder 31 is discharged through the one-way valve after being compressed.

[0049] With reference to Figure 8The electromagnet 24 is provided with five magnetic force surfaces (a magnetic force surface refers to a surface that can generate magnetic force after the electromagnet 24 is powered on), wherein the included angle between two groups of adjacent magnetic force surfaces is 135°, and the magnetic force surface in the middle is parallel to the horizontal plane, in order to facilitate description, the magnetic force surface in the middle is referred to as a material taking surface, and the magnetic force surfaces on both sides are referred to as material discharging surfaces.

[0050] When the repulsive force is generated on the material taking surface, the slide rod 32 drives the grabbing head 35 to move vertically downward to grab the waste, after the waste is grabbed, the material taking surface is powered off, the magnetic force is eliminated, and then the compressed spring 33 is reset, so as to drive the slide rod 32 to move towards the mounting column 21, at this time, the air pressure inside the piston cylinder 31 is lower than the outside of the piston cylinder 31, under the pressure difference, the external air enters the inside of the piston cylinder 31 through the air inlet hole 51 and pushes open the sealing gasket 52.

[0051] Referring to Figure 2 , Figure 3 and Figure 12 , the gas collecting pipe 53 is fixedly installed at the exhaust end of the piston cylinder 31, the exhaust hole 54 connected with the gas collecting pipe 53 is arranged on the connecting arm 22, the air hole 55 communicating with the exhaust hole 54 is arranged on the mounting column 21, the rotating joint 56 communicating with the air hole 55 is fixedly installed on the mounting column 21, the exhaust pipe 57 is fixedly installed at the output end of the rotating joint 56, and the exhaust pipe 57 is connected with the inner cavity of the limiting plate 15.

[0052] In use, the slide rod 32 drives the gas flow when reciprocally sliding, on the one hand, the damping generated by the gas flow buffers the extension and reset of the slide rod 32, avoids damage of the grabbing head 35 due to rapid impact, and prevents fragile and deformable waste from being damaged or deviated, so as to ensure the integrity of the grabbing process, on the other hand, the discharged gas is sent into the limiting plate 15 and discharged through the shunt hole 16, the discharged gas blows towards the upwardly bent wall of the conveying belt 13, so that the inclined wall of the conveying belt 13 slightly vibrates, the waste on the inclined wall of the conveying belt 13 is caused to separate from the wall, and finally falls into the middle region of the conveying belt 13, so as to avoid deviation of the position of the waste from the grabbing point of the grabbing head 35, and improve the grabbing precision.

[0053] Referring to Figure 2 and Figure 10 , the digital recognition system 6 includes the grating 61 fixedly installed on the second mounting frame 2, and the visual camera 62 fixedly installed on the side wall of the grating 61.

[0054] The grating 61 forms a light grid along the width direction of the conveying belt 13, and can output the three-dimensional space coordinates of the waste in the X axis (width direction of the conveying belt 13) and the Y axis (conveying direction) and the basic dimensions such as length and width by shielding the position and duration of the optical axis, and can also send a digital trigger signal to activate the subsequent equipment; after the visual camera 62 shoots the high-definition image of the waste, the color, texture, shape and other characteristics are converted into digital information such as RGB value and texture parameter through algorithm; the two types of data are transmitted to the control host in real time, and the waste type code, the type of grabbing head 35, the number of collection box slot 7 and other structured instructions are generated through digital fusion analysis, which drives the annular mounting bracket 23 of the grabbing part to rotate at a digital angle, and the slide rod 32 to extend by a digital distance, and all the collected waste position, type, sorting result and other data are also digitally stored, which provides accurate basis and traceable management for the sorting process.

[0055] With reference to Figure 1 and Figure 2 The collection box 7 is provided with a plurality of box slots, and the plurality of box slots are arranged in a stepped manner, and by controlling the extension distance of the slide rod 32, the grabbed waste can be placed into the corresponding box slot.

[0056] As described above, the edge waste is preliminarily gathered to the middle under the action of gravity through the action of bending the two sides of the conveying belt 13 upward, and further the waste on the belt wall is separated and rolled to the middle area by the airflow generated during the working of the grabbing part blowing to the inclined belt wall of the conveying belt 13 and vibrating it, so as to realize the accurate centering of the waste in the conveying process; this process ensures that all the waste to be grabbed is in the fixed middle area of the conveying belt 13, so that the annular mounting bracket 23 only needs to rotate at a preset fixed angle to complete the replacement and accurate positioning of the grabbing head 35, without the need to frequently adjust the rotation stroke due to the position deviation of the waste, which not only greatly simplifies the control logic and improves the grabbing efficiency, but also reduces the frequent speed and direction changes of the grabbing part, reduces the probability of grabbing empty and grabbing deviation, and through the functional reuse of the airflow, the additional correction power source is saved, which not only ensures the stability and service life of the grabbing, but also controls the cost, and improves the stability, grabbing accuracy and efficiency of the waste grabbing and sorting.

[0057] For the waste with slightly sticky surface, irregular shape (such as flaky and strip-shaped) or light weight attached to the wall of the conveying belt 13, gravity alone may cause residue, and the vibration of the conveying belt 13 driven by the airflow can form an active peeling effect, which can cover more waste centering needs of different shapes and reduce the positioning failure problem caused by special waste shape.

[0058] The combination of airflow vibration and gravity homing belongs to a non-contact and low-impact homing method, which can avoid the waste from being squeezed, scraped or collided and deformed compared with the hard correction structure such as mechanical raking plate and side pushing block used in the traditional device, and is convenient for recycling the recyclable solid waste (such as plastic parts, glass products, etc.) which needs to be kept in the original shape, and improves the value of resource utilization at the end.

[0059] After the precise homing of the waste, the grabbing head 35 can stably grab the waste, avoid the waste from falling or tilting in the transfer process due to the deviation of the grabbing position, and ensure that the waste can accurately fall into the corresponding stepped box groove, thereby reducing the error rate of waste classification and improving the sorting purity.

[0060] The airflow buffering mechanism of the grabbing part not only protects the grabbing head 35 and the waste, but also absorbs the impact force generated by the movement of the sliding rod 32, reduces the noise generated by the mechanical collision, and at the same time, the transmission belt 13 realizes stable homing through the limiting structure and airflow assistance, avoids the transmission belt 13 from being stuck and making abnormal sound due to the deviation of the waste, and overall reduces the environmental noise and equipment vibration during the operation of the device.

[0061] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above-mentioned embodiments are still within the scope of the present application.
