Description

Technical Field

[0001] This utility model relates to the field of automation control technology, specifically to an intelligent metering controller for a slatted sheet machine. Background Technology

[0002] A slatted conveyor, also known as a plate feeder, is a heavy-duty, continuous conveying device designed for handling large, heavy, high-temperature, sharp, or highly abrasive bulk materials. Its operating principle involves an electric motor driving a drive sprocket at the head via a reducer. This drives a chain and chain plates fixed to the chain to circulate along a support track. Material is evenly loaded onto the running chain plates from the feed inlet (usually at the tail or middle), and the chain plates continuously convey the material to the discharge outlet at the head. The operating speed is adjustable to control the material flow rate.

[0003] Existing metering controllers generally use bolt fastening for installation. However, in the vibrating environment of the equipment, the bolts are prone to loosening due to repeated stress, causing the controller body to shift or even fall off, which significantly shortens the service life of the metering controller. During maintenance, users need to use special tools to disassemble multiple sets of bolts one by one. Not only is each maintenance time-consuming and affects the planning of equipment downtime, but the unlocking process is also cumbersome and complicated, which greatly increases manpower and time costs. In addition, frequent disassembly and assembly will accelerate thread wear and structural component fatigue, requiring regular replacement of parts, which increases replacement costs. Summary of the Invention

[0004] The purpose of this utility model is to provide an intelligent metering controller for slatted board machines, which has the advantages of easy disassembly and assembly and good buffering effect, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent metering controller for a slatted board machine, including a back plate, a housing fixedly connected to the front side of the back plate, a metering controller body disposed within the inner cavity of the housing, a heat sink disposed within the inner cavity of the housing, a cooling fan embedded in the rear side of the back plate, a groove formed at the top of the front side of the housing, a first cavity formed at the rear side of the inner cavity of the groove, a square block disposed within the inner cavity of the first cavity, a fixing block fixedly connected to the front side of the square block, the front side of the fixing block fixedly connected to the metering controller body, a first limiting mechanism disposed at the rear side of the inner cavity of the first cavity, and two second cavities formed inside the square block, each second cavity having a second limiting mechanism disposed within its inner cavity.

[0006] Furthermore, as a preferred embodiment of this utility model, the first limiting mechanism includes two protrusions fixedly connected to the rear side of the inner cavity of the first cavity. A long rod is fixedly connected to one side of the two protrusions opposite to each other. Two sleeve blocks are slidably connected to the surface of the long rod. A first spring is sleeved on the surface of the long rod. Both ends of the first spring are fixedly connected to the sleeve blocks. A first connecting member is fixedly connected to the surface of the sleeve blocks. A connecting block is rotatably connected to the inner cavity of the first connecting member. A second connecting member is rotatably connected to the other end of the connecting block. A limiting plate is fixedly connected to the front sides of the two second connecting members.

[0007] Furthermore, in a preferred embodiment of this utility model, the second limiting mechanism includes a wedge-shaped block slidably connected to the inner cavity of the second cavity, a second spring fixedly connected to one side of the inner cavity of the second cavity, one end of the second spring penetrating into the inner cavity of the wedge-shaped block and fixedly connected to the wedge-shaped block, a movable block fixedly connected to the front side of the wedge-shaped block, a toothed plate fixedly connected to the front side of the movable block, a rotating rod rotatably connected to the front side of the square block, a gear sleeved on the surface of the rotating rod, and the toothed plate meshing with the gear.

[0008] Furthermore, as a preferred embodiment of this utility model, one end of the rotating rod extends through to the front side of the metering controller body and is fixedly connected to a handle, the handle being circular in shape.

[0009] Furthermore, as a preferred embodiment of this utility model, the inner cavity of the housing is provided with heat sinks, and a cooling fan is embedded in the rear side of the back plate.

[0010] Beneficial effects: The technical solution of this application has the following technical effects: This utility model has the advantages of easy disassembly and assembly and good buffering effect. In actual use, through the setting of the first limiting mechanism, when the square block enters the first cavity, the limiting plate compresses the first spring through the connecting block and the sleeve block, and uses the elastic potential energy of the first spring to achieve buffering, avoiding damage to the equipment caused by hard collision. The rebound force of the first spring keeps the limiting plate in close contact with the square block, eliminating installation gaps and preventing the square block from loosening or shifting due to vibration or impact, thus improving the reliability of fixation. Through the setting of the second limiting mechanism, during installation, the wedge block is automatically retracted into the second cavity by the pressure of the inner wall of the groove, and quick locking is achieved by the rebound of the second spring. During disassembly, the gear is driven to rotate by turning the handle, which drives the toothed plate and the wedge block to retract synchronously, thereby realizing the unlocking function and significantly improving maintenance efficiency.

[0015] As attached Figure 1 To be continued Figure 6As shown: This embodiment provides an intelligent metering controller for a slatted board machine, including a back plate 1, a housing 2 fixedly connected to the front side of the back plate 1, a metering controller body 3 disposed in the inner cavity of the housing 2, a heat sink 4 disposed in the inner cavity of the housing 2, a cooling fan 5 embedded in the rear side of the back plate 1, a groove 13 opened at the top of the front side of the housing 2, a first cavity 6 opened at the rear side of the inner cavity of the groove 13, a square block 7 disposed in the inner cavity of the first cavity 6, a fixing block 8 fixedly connected to the front side of the square block 7, the front side of the fixing block 8 fixedly connected to the metering controller body 3, a first limiting mechanism 9 disposed at the rear side of the inner cavity of the first cavity 6, two second cavities 10 opened inside the square block 7, and a second limiting mechanism 11 disposed in the inner cavity of the second cavity 10.

[0016] Specifically: The metering controller uses an STM32 chip for internal calculation, edge computing, and filtering to obtain the real-time conveying capacity of the slatted conveyor. It then uses data comparison to control the output analog current to adjust the frequency of the slatted conveyor's inverter, thereby adjusting the inverter's conveying capacity. The metering controller consists of one computing controller, two angle sensors, and one speed sensor. The angle sensors are installed on the side of the slatted conveyor, and the speed sensor is installed on the tail shaft. During operation, the angle sensors measure the rotational intersection value with the pressure plate, and then calculate the height difference using the angle difference. This height difference represents the material layer value. The speed sensor on the tail shaft measures the angular velocity of the tail shaft. The gear ratio of the reducer is used to calculate the linear speed of the conveyor chain, which in turn calculates the conveying distance per unit time. The width of the slatted conveyor is a design value. By calculating the material height difference, the conveying distance per unit time, and the width of the slatted conveyor, the conveying capacity per unit time can be obtained. Finally, the real-time conveying capacity of the slatted conveyor is calculated.

[0017] In this embodiment, the metering controller body 3 can monitor the conveying volume of the slatted board machine in real time, and convey the equipment to the set standard volume through intelligent learning and edge computing closed-loop control, thereby reducing the error rate of manual operation; the adjustment lag time is greatly reduced, saving operating costs.

[0018] Specifically, the first limiting mechanism 9 includes two protrusions 91 fixedly connected to the rear side of the inner cavity of the first cavity 6. A long rod 92 is fixedly connected to one side of the two protrusions 91. Two sleeve blocks 93 are slidably connected to the surface of the long rod 92. A first spring 94 is sleeved on the surface of the long rod 92. Both ends of the first spring 94 are fixedly connected to the sleeve blocks 93. A first connecting member 95 is fixedly connected to the surface of the sleeve blocks 93. A connecting block 96 is rotatably connected to the inner cavity of the first connecting member 95. A second connecting member 97 is rotatably connected to the other end of the connecting block 96. A limiting plate 98 is fixedly connected to the front sides of the two second connecting members 97.

[0019] In this embodiment: by setting the first limiting mechanism 9, when the square block 7 enters the first cavity 6, the limiting plate 98 compresses the first spring 94 through the connecting block 96 and the sleeve block 93, and uses the elastic potential energy of the first spring 94 to achieve buffering, avoiding damage to the equipment caused by hard collision. The rebound force of the first spring 94 keeps the limiting plate 98 in close contact with the square block 7, eliminating installation gaps, preventing the square block 7 from loosening or shifting due to vibration or impact, and improving the reliability of fixing.

[0020] Specifically, the second limiting mechanism 11 includes a wedge block 111 slidably connected to the inner cavity of the second cavity 10. A second spring 112 is fixedly connected to one side of the inner cavity of the second cavity 10. One end of the second spring 112 passes through the inner cavity of the wedge block 111 and is fixedly connected to the wedge block 111. A movable block 113 is fixedly connected to the front side of the wedge block 111. A toothed plate 114 is fixedly connected to the front side of the movable block 113. A rotating rod 115 is rotatably connected to the front side of the square block 7. A gear 116 is sleeved on the surface of the rotating rod 115. The toothed plate 114 meshes with the gear 116.

[0021] In this embodiment: by setting the second limiting mechanism 11, during installation, the wedge block 111 is squeezed by the inner wall of the groove 13 and automatically retracts into the second cavity 10. The second spring 112 rebounds to achieve quick locking. During disassembly, the handle 12 drives the gear 116 to rotate, which drives the toothed plate 114 and the wedge block 111 to retract synchronously, thereby realizing the unlocking function and significantly improving maintenance efficiency.

[0022] Specifically, one end of the rotating rod 115 extends through to the front of the metering controller body 3 and is fixedly connected to a handle 12, which is circular in shape.

[0023] In this embodiment, the handle 12 increases the contact area between the user's palm and the handle 12, thereby making it easier for the user to rotate the gear 116.

[0024] Specifically, the inner cavity of the housing 2 is provided with heat sink 4, and the rear side of the back plate 1 is embedded with a heat dissipation fan 5.

[0025] In this embodiment: the heat sink 4 can dissipate heat from the metering controller body 3. By activating the cooling fan 5, the cooling fan 5 can also dissipate heat from the inner cavity of the housing 2, thereby extending the service life of the metering controller body 3.

[0026] The working principle and usage process of this utility model: The user places the metering controller body 3 into the inner cavity of the housing 2. The rear side of the metering controller body 3 will come into contact with the heat sink 4. The heat sink 4 can dissipate heat from the metering controller body 3. By starting the cooling fan 5, the cooling fan 5 can also dissipate heat from the inner cavity of the housing 2, thereby extending the service life of the metering controller body 3.

[0027] When the metering controller body 3 moves, it drives the fixed block 8 to move. The fixed block 8 drives the square block 7 into the inner cavity of the groove 13. As the metering controller body 3 continues to move, the wedge block 111 comes into contact with the inner wall of the groove 13. As the metering controller body 3 continues to move backward, the wedge block 111 is pressed against the inner wall of the groove 13, causing the wedge block 111 to move into the inner cavity of the second cavity 10. When the wedge block 111 moves, it drives the second spring 112 to compress. At the same time, the wedge block 111 also drives the movable block 113 to move. 13 drives the toothed plate 114 to move, so that the two toothed plates 114 move relative to each other. When the toothed plate 114 moves, it drives the gear 116 to rotate. The gear 116 drives the rotating rod 115 to rotate. When the wedge block 111 is completely inserted into the inner cavity of the second cavity 10, the metering controller body 3 continues to move backward, so that the square block 7 enters the inner cavity of the first cavity 6. When the square block 7 moves to a specified distance, the rebound force of the second spring 112 will drive the wedge block 111 to pop out, thereby limiting the square block 7 and preventing the square block 7 from leaving the inner cavity of the first cavity 6.

[0028] When the square block 7 enters the inner cavity of the first cavity 6, it contacts the limiting plate 98. As the square block 7 moves, the limiting plate 98 moves backward, causing the limiting plate 98 to move the second connecting member 97. The second connecting member 97 causes one end of the connecting block 96 to move backward, while the other end of the connecting block 96 causes the first connecting member 95 to move, so that the two first connecting members 95 move relative to each other. The first connecting member 95 causes the sleeve block 93 to slide on the surface of the long rod 92. When the long rod 92 slides, it causes the first... When the spring 94 is compressed, the movement of the metering controller body 3 will stop once the wedge block 111 is fully inserted into the inner cavity of the first cavity 6. At this time, the elastic force of the long rod 92 will cause the limiting plate 98 to come into close contact with the square block 7. The limiting plate 98 will drive the square block 7 to move forward, and the square block 7 will drive the wedge block 111 to move, so that the front side of the wedge block 111 comes into contact with the inner wall of the first cavity 6, thereby effectively fixing the square block 7 and preventing the square block 7 from displacing in the inner cavity of the first cavity 6.

[0029] When it is necessary to disassemble the metering controller body 3, the user rotates the handle 12, which drives the rotating rod 115 to rotate. When the rotating rod 115 rotates, it drives the two toothed plates 114 to move relative to each other. The toothed plates 114 drive the movable block 113 to move. The movable block 113 drives the wedge block 111 to move into the inner cavity of the second cavity 10. When the wedge block 111 moves, it drives the second spring 112 to compress. When the wedge block 111 is fully inserted into the inner cavity of the second cavity 10, the metering controller body 3 is moved forward. The metering controller body 3 drives the fixed block 8 to move. The fixed block 8 drives the square block 7 to disengage from the inner cavity of the first cavity 6, thus facilitating the user to disassemble and repair the metering controller body 3.
