Technical Field

[0001] The utility model relates to the field of environmental protection equipment, in particular to waste recycling equipment and a feeding mechanism. Background Art

[0002] Waste recycling is an important measure to maintain environmental hygiene, protect the health of citizens, promote resource recycling and achieve sustainable development. Waste recycling is an important part of waste recycling, an important part of resource recycling and environmental protection, and is of great significance to promoting sustainable development. Waste recycling refers to the process of collecting, sorting, processing and treating recyclable materials in waste so that they can re-enter the production cycle. In the process of waste recycling, the existing loading method is to directly pile the waste on the conveyor belt. When the amount of waste is large, it will cause material blockage on the conveyor belt, and it is easy for waste to fall.

[0003] Therefore, providing a waste recycling device and a feeding mechanism to solve the problem of waste accumulation on the conveyor belt and easy waste falling during the waste recycling process has become an urgent problem to be solved by technical personnel in this field.

[0043] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0044] In a specific implementation manner, as Figures 1-8 shown, the feeding mechanism provided by the present utility model is used for waste recycling equipment. The feeding mechanism includes a hopper, a material conveying assembly, and a control unit. Among them, the hopper is used to collect and store waste to be recycled, and the waste enters the material conveying assembly through the feeding port of the hopper. Specifically, the hopper can be formed by inclined plates arranged on both sides of the material conveying assembly. The plate members on both sides are inclined to form a flared shape with a large top and a small bottom. The inclination angle of the inclined plate can be 30° - 60°, so as to ensure the smooth feeding of materials. A mesh plate is arranged at the end of the inclined plate, and a discharge door is opened on the mesh plate. In order to prevent the materials from overflowing due to excessive height, a baffle can be arranged above the hopper. The baffle can be a mesh structure plate specifically, and multiple groups of baffles can be arranged to surround the entire hopper. For the convenience of equipment maintenance, a maintenance door can also be opened on the baffle. The maintenance door can be reversibly connected to the baffle by a pivot connection structure so as to be turned over and opened vertically. To ensure the stability of the equipment, a support frame can be arranged at the bottom of the entire feeding mechanism. The support frame has a leg structure, and the legs can be selected in a structure with adjustable height.

[0045] The feeding assembly is arranged below the hopper and receives the materials dropped from the hopper. The feeding assembly includes a first conveyor belt and a second conveyor belt arranged at intervals in the vertical direction. The second conveyor belt is located above the first conveyor belt and partially covers the belt surface of the first conveyor belt on the vertical projection surface. The first conveyor belt moves horizontally in a first direction when driven by a first power component, and the second conveyor belt moves horizontally in a first direction or a second direction when driven by a second power component. The first direction is opposite to the second direction.

[0046] Specifically, the first power component and the second power component can both be motors. For the convenience of description, the first power component is the first motor and the second power component is the second motor; the first power component is used to drive the first conveyor belt to move horizontally in the first direction. In theory, it can be a motor, a pneumatic motor or a hydraulic motor. In the waste recycling feeding mechanism, the motor is cost-effective, easy to control and relatively simple to maintain, and is a better implementation method. The motor is connected to the drive shaft of the first conveyor belt by belt drive, gear drive or direct drive, so that it moves at a set speed and direction. The second power component is used to drive the second conveyor belt to move horizontally in the first direction or the second direction. Similar to the first power component, the second power component can also be a motor, a pneumatic motor or a hydraulic motor. The type of power component to be selected depends on the power, speed and control requirements required by the conveyor belt.

[0047] The control unit is used to receive the current stockpile height in the hopper; when the current stockpile height reaches a first preset height, the control unit sends a start instruction to the second power component to make the second power component move at an initial speed; when the current stockpile height is higher than a second preset height, the control unit sends a first speed regulation instruction to the second power component so that the second power component accelerates relative to the initial speed according to the first speed regulation instruction; when the current stockpile height is lower than the first preset height, the control unit sends a second speed regulation instruction to the second power component so that the second power component decelerates relative to the initial speed according to the second speed regulation instruction, and adjusts the movement speed of the second conveyor belt according to the current stockpile height in the hopper.

[0048] In order to ensure that a speed difference can be generated between the two conveyor belts, thereby achieving the effect of using the second conveyor belt to reduce the amount of material falling from the first conveyor belt, when the second conveyor belt moves along the first direction, the control unit controls the first power component and the second power component so that the movement speed of the first conveyor belt in the first direction is greater than the movement speed of the second conveyor belt in the first direction.

[0049] That is to say, when the stacking height of the material in the hopper increases, the control unit will detect this change and correspondingly increase the moving speed of the second conveyor belt to prevent excessive waste products from entering the first conveyor belt and blocking the outlet of the feeding mechanism; when the stacking height of the material in the hopper decreases, the control unit will slow down the moving speed of the second conveyor belt to ensure the waste material transportation. Through the intelligent adjustment of the control unit, the smooth flow of waste products from the hopper to the material conveying assembly is ensured, and the efficiency and safety of waste product recycling are improved. During the working process, the waste products are directly unloaded into the hopper and fall into the material conveying assembly. When the current stacking height in the hopper reaches a preset first preset height, the second power component is started to move relative to the second conveyor belt, and by moving in the same or different directions at different speeds from the first conveyor belt, a speed difference is generated between the two conveyor belts, so that a part of the material falling from the hopper will be carried away in the reverse direction by the second conveyor belt before falling onto the first conveyor belt, and only a small amount of material falls onto the first conveyor belt, thereby reducing the accumulation of material on the first conveyor belt and improving the feeding efficiency and feeding effect.

[0050] In some embodiments, the second conveyor belt includes a sprocket drivingly connected to the second power component and a chain plate bypassing the sprocket. It should be understood that the sprocket includes a driving sprocket and a driven sprocket. The driving sprocket is drivingly connected to the second power component, and the driven sprocket is drivingly connected to the second power component through the transmission of the chain plate; specifically, a guide groove plate can be installed on the support frame, and the chain plate is arranged in the guide groove laterally opened in the guide groove plate to improve the guiding property during the movement of the chain plate and prevent the chain plate from shifting. The guide groove plates are preferably two groups, and both ends of the chain plate are respectively located in the guide grooves of the two guide groove plates. When the sprocket is drivingly connected to the second power component and the second power component is a second motor, the output shaft of the second motor is fixedly connected to the sprocket. When the second power component (such as a motor) rotates, the sprocket will also rotate accordingly, thereby driving the chain plate to move; the chain plate bypasses the sprocket and is the medium for transmitting power, ensuring that the entire conveyor belt can move continuously; the chain plate constitutes the belt surface of the conveyor belt. When the second power component is started, it drives the sprocket to rotate through the driving connection, and the rotation of the sprocket causes the chain plate bypassing it to move accordingly, thereby driving the chain plate to move horizontally. Since the chain plate constitutes the belt surface of the conveyor belt, the transportation of the material is realized through the movement of the chain plate. The second power component needs to be able to adjust the rotation speed and direction of the sprocket according to the instructions of the control unit to achieve the efficient transportation and distribution of the material. The control unit adjusts the output of the second power component according to the stacking height of the material in the hopper, thereby controlling the movement speed and direction of the chain plate, enabling the second conveyor belt to flexibly respond to the change in the material flow rate, ensuring that the material can be removed from the hopper in a timely manner, and at the same time preventing the material from accumulating on the first conveyor belt.

[0051] During the entire working process, the sprocket and the chain plate of the second conveyor belt work together and cooperate closely with the second power component, achieving efficient conveying and precise distribution of materials, and improving the performance and reliability of the waste recycling feeding mechanism.

[0052] In some embodiments, the chain plate includes a plurality of plate bodies, and adjacent plate bodies are detachably connected by connecting pieces. In this way, the chain plate is composed of a plurality of plate bodies, each plate body being a unit on the chain, responsible for carrying materials and moving along with the chain. Adjacent plate bodies are connected by connecting pieces, and the connecting pieces are of a detachable structure, enabling the plate bodies to be easily removed or replaced. With the detachable connection structure, since the plate bodies are connected by detachable connecting pieces, when maintaining and replacing the chain plate, the damaged or worn plate bodies can be individually removed without the need to replace the entire chain plate, which greatly reduces the maintenance cost and downtime; the detachable connecting pieces enable the chain plate to be adjusted according to different material types and working environments. For example, if heavier materials need to be carried, stronger plate bodies and connecting pieces can be selected; when the chain plate needs to be lengthened or shortened, the length of the chain plate can be quickly adjusted by increasing or decreasing the number of plate bodies to meet different conveying requirements; when the chain plate is damaged or worn, maintenance personnel can quickly use tools to remove the damaged plate body and replace it with a new one without complex operations or professional skills; the plate bodies and connecting pieces of the chain plate can be customized according to specific application requirements to optimize the performance and efficiency of material conveying.

[0053] During the entire working process, the design of the chain plate fully considers the convenience, adaptability, and flexibility of maintenance, enabling the second conveyor belt to better adapt to different working environments and material handling requirements, and improving the overall efficiency and reliability of the waste recycling feeding mechanism.

[0054] In some embodiments, the connecting piece is a transfer plate, and both ends of the transfer plate are screwed to adjacent two plate bodies respectively. The transfer plate, as the connecting piece, is used to connect adjacent two plate bodies together to form a continuous chain plate. The connecting plate is a key component of the chain plate, ensuring the integrity and continuity of the chain plate. The transfer plate not only connects the plate bodies but also is responsible for transmitting power, enabling the chain plate to move smoothly as the chain and sprocket rotate; both ends of the transfer plate are connected to adjacent two plate bodies by screws respectively. This connection method is simple and firm, ensuring the stable and reliable connection between the plate bodies; due to the use of screw connection, the connection between the transfer plate and the plate bodies can be easily disassembled, facilitating maintenance and replacement. When it is necessary to replace the plate body or adjust the chain plate, only the corresponding screws need to be removed; the screw connection method of the transfer plate makes the maintenance of the chain plate more convenient and fast. When the chain plate is worn or damaged, the damaged plate body or transfer plate can be quickly replaced, reducing the maintenance time and cost.

[0055] During the entire working process, the screw connection method of the adapter plate provides a stable and reliable connection for the chain plate, while taking into account the convenience and adaptability of maintenance, enabling the second conveyor belt to better adapt to different working environments and material handling requirements, and improving the overall efficiency and reliability of the waste recycling feeding mechanism.

[0056] In addition to the above feeding mechanism, the present utility model also provides a waste recycling device including this feeding mechanism. The waste recycling device includes a feeding mechanism, an appraisal mechanism, and a sorting mechanism. The appraisal mechanism is arranged downstream of the feeding mechanism, and the sorting mechanism is arranged downstream of the appraisal mechanism. For the structures of other parts of the waste recycling device, please refer to the prior art and will not be elaborated here.

[0057] The present utility model also provides a feeding control method based on the feeding mechanism as described above. As Figure 9 shown, the method includes the following steps:

[0058] S910: Obtain the current stacking height in the hopper; for example, sensors (such as ultrasonic sensors, photoelectric sensors, etc.) can be used to monitor the stacking height in the hopper in real time, and transmit the sensor data to the control unit.

[0059] S920: Generate a start command when the current stacking height reaches a first preset height. The start command is used to control the second power component to move at an initial speed; for example, the first preset height can be any value in the range of 0.1 - 0.5 m, and the initial speed can be any value in the range of 1 m / s - 10 m / s; taking the first preset height of 0.2 m and the initial speed of 8 m / s as an example, when the first preset height is 0.2 m, start the second power component to make the second power component move at a speed of 8 m / s.

[0060] S930: After the second power component is started, generate a first speed regulation command when the current stacking height is higher than a second preset height. The first speed regulation command is used to control the second power component to accelerate relative to the initial speed according to the first speed regulation command; in the actual use scenario, if the stacking height is too high and the material still moves at the initial speed, it may cause the accumulation of materials on the first conveyor belt due to the insufficient buffering effect of the second conveyor belt to relieve the accumulation of a large amount of materials, resulting in the blockage of the outlet of the conveying mechanism; to solve this problem, it is necessary to increase the speed of the second conveyor belt to speed up the reverse conveying of materials and avoid the accumulation of a large amount of materials on the first conveyor belt.

[0061] S940: After the second power component is started, when the current stockpiling height is lower than the first preset height, a second speed regulation instruction is generated, and the second speed regulation instruction is used to control the second power component to decelerate relative to the initial speed according to the second speed regulation instruction; that is to say, when the stockpiling height is low, the risk of material accumulation on the first conveyor belt is low, and at this time, the speed of the second conveyor belt can be appropriately reduced to reduce energy consumption.

[0062] In some embodiments, an ultrasonic sensor or a photoelectric sensor can be used to collect the current material height; among them, the ultrasonic sensor measures the distance by emitting and receiving ultrasonic waves, and it can be installed on the hopper wall. When the ultrasonic waves encounter the material, part of the waves are reflected back, and the sensor receives these reflected waves and calculates the height of the material accordingly. The photoelectric sensor uses the reflection of light to measure the distance, and it usually includes a transmitter and a receiver. When the emitted light is reflected by the material, the receiver receives the reflected light, thereby calculating the height of the material.

[0063] In one embodiment, a computer device is provided. The computer device can be a server, and its internal structure diagram can be as Figure 10 shown. The computer device includes a processor, a memory, and a network interface connected through a system bus.
