Description

Technical Field

[0001] This invention relates to the technical field of sheet metal processing, specifically to an intelligent feeding mechanism for a press metering belt. Background Technology

[0002] As is known, in the process of preparing high-density fiberboard, it is necessary to control the material flow from the silo to the laying device, and it is also necessary to accurately control the amount of material discharged from the silo, i.e. the amount of material input to the laying device. Therefore, in the existing technology, metering belts or belt scales are generally used to achieve accurate output of materials in the silo.

[0003] For example, a patent with announcement number CN104444422B, announcement date June 19, 2017, and titled "A Dual Weighing Measuring Silo," includes: a belt conveyor mechanism; a silo mounted on the belt conveyor mechanism, wherein a feed inlet is provided at the top of the silo near the rear end along the conveying direction of the belt conveyor mechanism, and a discharge outlet is provided at the bottom of the silo near the front end along the conveying direction of the belt conveyor mechanism; a large-capacity weighing mechanism installed within the belt conveyor mechanism and positioned near the feed inlet of the silo, with its vertical projection onto the belt conveyor mechanism; and a discharge outlet installed within the belt conveyor mechanism and located at the discharge outlet of the silo. A small-range weighing mechanism is located behind the feed inlet; the belt conveyor mechanism includes a frame, a drive roller, a driven roller, a belt, and a drive device. The drive roller shaft is located at the rear end of the frame, and the driven roller shaft is located at the front end of the frame. The belt wraps around the drive roller and the driven roller. The drive device is mounted on the frame and drives the drive roller to rotate. The bin is supported on the frame of the belt conveyor mechanism by a bin frame. A throwing device is located in the bin below the feed inlet and between the large-range weighing mechanism and the small-range weighing mechanism. The throwing device includes a throwing roller bracket, several throwing rollers, and a drive motor that drives the several throwing rollers to rotate.

[0004] In the prior art, the belt conveyor mechanism in the aforementioned authorized patent is a metering mechanism. Intelligent feeding control of materials in the silo can be achieved through the belt conveyor mechanism. However, since a part of the belt conveyor mechanism is installed through the bottom of the silo, when the silo is full of materials, the weight of the entire material in the silo will be applied to the belt conveyor mechanism. That is, the belt conveyor mechanism bears the weight of a large amount of material in the entire silo, rather than carrying the material delivered in a single batch. This leads to increased wear and energy consumption of the belt conveyor mechanism during operation. Furthermore, slippage may occur between the rollers and the belt in the belt conveyor mechanism, which will affect the feeding control of materials. Summary of the Invention

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 5 The present invention will now be described in further detail.

[0028] This invention provides a press metering belt intelligent feeding mechanism, including a hopper 1 and a metering conveying mechanism 2. The metering conveying mechanism 2 is installed through the inside of the hopper 1 and is used to send the material from the hopper 1 out of the discharge port 11. A baffle 13 is also installed inside the hopper 1 and is installed above the metering conveying mechanism 2.

[0029] Specifically, the metering conveyor 2 is a metering belt, which can also be understood as a belt scale or a weighing mechanism installed inside the conveyor belt. It is used to calculate the output material quantity during material conveying. This is existing technology and will not be elaborated further. A baffle 13 is horizontally arranged above the metering conveyor 2, dividing the hopper 1 into a first chamber 16 and a second chamber 17. The first chamber 16 is located above the second chamber 17. The baffle 13 has holes through which the first chamber 16 and the second chamber 17 are interconnected. When material is conveyed into the hopper 1 from the inlet, the material in the hopper 1 first enters the first chamber 16. Some of the material accumulates on the baffle 13, while the other part enters the second chamber 17 through the holes and falls onto the metering conveyor 2. As material continues to be input into the hopper 1, the material in the first chamber 16... The space is gradually filled with materials, and the materials in the first chamber 16 are continuously entering the second chamber 17 through the holes. At the same time, the metering and conveying mechanism 2 continuously sends the materials in the second chamber 17 out from the feed port. Due to the design of the baffle 13, during the process of conveying materials, the metering and conveying mechanism 2 only needs to bear the weight of the materials in the second chamber 17, while the materials in the first chamber 16 are supported by the baffle 13. Therefore, under the action of the baffle 13, the weight of materials borne by the metering and conveying mechanism 2 during the material conveying process is reduced, and the problem of increased energy consumption due to excessive load is also reduced.

[0030] In another embodiment of the present invention, a drive assembly 18 is further installed on the side of the hopper 1. The drive assembly 18 is connected to the baffle 13. The drive assembly 18 is used to drive the baffle 13 to move horizontally back and forth in the hopper during the feeding process of the metering and conveying mechanism 2.

[0031] Specifically, support blocks 14 are symmetrically arranged on both sides of the baffle 13. The support blocks 14 are fixedly connected to the inside of the hopper 1. The two ends of the baffle 13 extend into the two sets of support blocks 14 respectively. The support blocks 14 have grooves 15 inside. The baffle 13 and the grooves 15 form a sliding guide fit. In this embodiment, a drive assembly 18 is installed on the side of the hopper 1. The drive assembly 18 can be a linear drive mechanism such as an electric push rod or a cylinder. The output shaft of the drive assembly 18 passes through the wall of the hopper 1 to connect to the baffle 13. During the feeding process of the metering and conveying mechanism 2, the drive assembly 18 drives the baffle 13 to move horizontally back and forth between the first chamber 16 and the second chamber 17, that is, to slide between the two sets of support blocks 14. This back and forth movement can accelerate the movement speed of the material in the first chamber 16 into the second chamber 17, so that the material in the first chamber 16 can smoothly enter the second chamber 17 through the hole and fall on the metering and conveying mechanism 2. The metering and conveying mechanism 2 sends the material out from the outlet 11.

[0032] The raw material for high-density fiberboard is wood fiber. In this embodiment, the material in the hopper 1 is wood fiber. Since wood fiber is highly hygroscopic, it is easy to adhere and clump together. When the clumps of wood fiber enter the subsequent laying and other processes, it will cause problems such as uneven laying, uneven board density, reduced strength, and surface defects. Therefore, in order to prevent the clumps of material in the hopper 1 from being sent out from the discharge port 11, in another embodiment of the present invention, a filter mechanism 3 for filtering clumps of material is further installed inside the second chamber 17. The filter mechanism 3 is installed directly below the baffle 13.

[0033] Specifically, the filtration mechanism 3 includes a filter screen 31 installed below the baffle 13. The filter screen 31 is connected to the baffle 13 via a connecting rod 36. When the baffle 13 moves horizontally back and forth, the filter screen 31 moves synchronously, that is, the filter screen 31 moves horizontally back and forth in the second chamber 17, or swings left and right. When the material falls through the holes of the baffle 13, the material will fall onto the filter screen 31. The filter screen 31 filters the clumps in the material. The fine wood fibers in the material pass through the filter screen 31 and fall onto the metering and conveying mechanism 2, while the clumps remain on the filter screen 31. Furthermore, the left and right swinging of the filter screen 31 in the second chamber 17 can reduce the accumulation of material on the filter screen 31, so that the filtration of the material can proceed smoothly.

[0034] It should be further explained that although the baffle 13 has holes, the holes on the baffle 13 have a large diameter and the first chamber 16 contains a large amount of material. Therefore, in this embodiment, the baffle 13 only serves to support the material in the first chamber 16 and allow the material to leak into the second chamber 17 through the holes. It does not filter the material in the first chamber 16. Furthermore, the amount of material in the first chamber 16 is large, so the baffle 13 and its holes are also insufficient to filter the material.

[0035] To avoid the accumulation of agglomerated materials on the filter screen, the filter screen is traditionally tilted so that the agglomerated materials are discharged along the tilt direction of the filter screen. However, the tilted filter screen will also discharge fine materials, i.e., non-agglomerated wood fibers. In other words, some normal materials will be sent out, resulting in waste of these materials. Therefore, in another embodiment, the filter mechanism 3 further includes a connecting plate 33 and a fixed frame 32. The fixed frame 32 is suspended below the baffle 13 by a connecting rod 36. The two ends of the connecting plate 33 are fixedly connected to the fixed frame 32. Multiple sets of connecting plates 33 are provided, and the multiple sets of connecting plates 33 are equidistantly arranged along the length direction of the fixed frame 32. The filter screen 31 is installed between two adjacent sets of connecting plates 33. A wedge block 34 is installed on the upper surface of the connecting plate 33.

[0036] Specifically, the connecting plate 33 is provided in multiple sets, and each set of connecting plates 33 is provided with a wedge block 34. The length direction of the connecting plate 33 and the wedge block 34 is consistent with the width direction of the fixed frame 32. The connecting plate 35 is installed inside the second chamber 17, and the fixed frame 32 rests on the connecting plate 35. The upper end of the connecting rod 36 is fixedly connected to the baffle 13, and the lower end is fixedly connected to the fixed frame 32. The wedge block 34 has an inclined guide slope 342 and an arc-shaped blocking surface 341, such as... Figure 3 and Figure 4 As shown, the blocking surface 341 is located on the left side of the wedge block 34, and the guide slope 342 is located on the right side of the wedge block 34. The left side of the second chamber 17 is provided with a discharge port 12 for discharging agglomerated materials. That is, the arc-shaped blocking surface 341 on the wedge block 34 is located on the side closer to the discharge port 12. In actual use, the fixed frame 32 moves horizontally back and forth synchronously with the baffle 13. The fixed frame 32 drives the connecting plate 33 and the filter screen 31 to move synchronously. At this time, the fixed frame 32 slides on the connecting plate 35. During the horizontal back and forth movement of the filter mechanism 3, in this embodiment, the movement stroke of the filter mechanism 3 from right to left is called the first stroke. The first stroke is the movement of the filter mechanism 3 towards the side closer to the discharge port 12. The movement stroke from left to right is called the second stroke. The second stroke is the movement of the filter screen 31 towards the side away from the discharge port 12.

[0037] In the first stroke, the fixed frame 32 moves in the second chamber 17 toward the side closer to the discharge port 12, and drives the filter screen 31 and the wedge block 34 to move synchronously. During the movement, the arc-shaped blocking surface 341 of the wedge block 34 directly abuts against the agglomerated material in front of it. Since both the filter screen 31 and the wedge block 34 are moving toward the side closer to the discharge port 12, and the arc-shaped blocking surface 341 of the wedge block 34 provides a strong barrier, the material (especially the agglomerated part with greater friction with the screen surface) is pushed by the arc-shaped blocking surface 341 of the wedge block 34 and moves a distance toward the side closer to the discharge port 12 together with the filter screen 31.

[0038] In the second stroke, the fixed frame 32 moves away from the discharge port 12 within the second chamber 17, causing the filter screen 31 and wedge block 34 to move synchronously. At this time, the material on the filter screen 31 tends to maintain its current position or move only slightly due to its own gravity and inertia. As the wedge block 34 moves, the material moves onto the guide slope 342 due to inertia, that is, the guide slope 342 and the material move relative to each other. The guide slope 342 also lifts the material in contact with it upwards. At this time, relative movement occurs between the material and the filter screen 31. During the process of the material being lifted upwards, the filter screen... 31 moves away from the discharge port 12. When the material falls back onto the filter screen 31, it is closer to the discharge port 12 than its initial position. In the subsequent first stroke, it is easier for the wedge block 34 to move the agglomerated material in the material towards the discharge port 12. By repeating this process, the agglomerated material can be continuously moved towards the discharge port 12. To ensure that the agglomerated material can cross the guide slope 342 during the above process, the speed of the second stroke can be faster. This instantaneous acceleration can ensure that the agglomerated material and the guide slope 342 move relative to each other.

[0039] In summary, the wedge block 34 forms a unidirectional structure on the connecting plate 33 and the filter screen 31. In the first stroke, due to the slow movement speed of the fixed frame 32 and the obstruction of the arc-shaped blocking surface 341 on the wedge block 34, the material remains relatively stationary with respect to the filter screen 31. The movement of the filter screen 31 towards the discharge port 12 will cause the material on it to move synchronously. In the second stroke, the fixed frame moves faster, and the material remains stationary. At this time, the filter screen 31 moves away from the discharge port, and the material moves relative to the filter screen 31. The material is equivalent to moving a distance on the filter screen towards the discharge port 12. Therefore, with the combination of the first and second strokes, the wood fibers fall off the filter screen 31 during the movement. The clumps of wood fibers move on the filter screen 31 towards the discharge port 12 and are eventually discharged from the discharge port 12. At this time, they can be collected by an external collection device.

[0040] In the above embodiment, during the second stroke, the material will be transported to the guide slope 342 due to inertia. Since the guide slope 342 has an inclined slope, the inclined slope also blocks the material from moving towards the discharge port 12 on the filter screen 31 to a certain extent. Therefore, in another embodiment of the present invention, the wedge block 34 further includes a first state and a second state. In the first state, the wedge block 34 is located on the surface of the connecting plate 33, and in the second state, the wedge block 34 is located inside the connecting plate 33.

[0041] Specifically, the first state of the wedge block 34 is its natural state when it extends out of the connecting plate 33. In the second state, the wedge block 34 is retracted into the connecting plate 33. At this time, the guide slope 342 of the wedge block 34 and the filter surface of the filter screen 31 are on the same horizontal plane, which can reduce the resistance to the material moving onto the guide slope 342. An adjustment mechanism 4 is installed in the hopper 1. The adjustment mechanism 4 is used to adjust the movement of the wedge block 34 from the first state to the second state.

[0042] More specifically, during the first stroke, the wedge block 34 remains in the first state, that is, the wedge block 34 protrudes from the surface of the connecting plate 33. The filter screen 31 and the wedge block 34 on it move synchronously towards the side closer to the discharge port 12. At this time, the agglomerated material on the filter screen 31 will tend to move away from the discharge port 12. Because the wedge block 34 protrudes from the connecting plate 33 in the first state, the material will move synchronously with the filter screen 31 towards the side closer to the discharge port 12 under the obstruction of the arc-shaped blocking surface 341 of the wedge block 34. It can be understood that the blocking surface 341 pushes the material towards the side closer to the discharge port 12.

[0043] At the end of the first stroke and before the start of the second stroke, the adjusting mechanism 4 drives the wedge block 34 to passively switch from the first state to the second state. That is, before the end of the first stroke, before the fixed frame 32 and the filter screen 31 stop moving, the agglomerated material on the filter screen 31 will move towards the side closer to the discharge port 12 due to the inertia generated when it stops. At this time, the formation of the second state, that is, the disappearance of the guide slope 342, can avoid the inclination of the guide slope 342 from blocking the inertial movement of the agglomerated material, and increase the distance that the agglomerated material moves towards the discharge port 12.

[0044] During the second stroke, the wedge block 34 remains in the second state. Because the filter screen 31 moves faster with the fixed frame 32, the agglomerated material on the filter screen 31 tends to move towards the side closer to the discharge port 12. This can be understood as the material remaining stationary while the filter screen 31 moves below the material. Relative movement occurs between the material and the filter screen 31. After the guide slope 342 is level with the mesh surface of the filter screen 31, the agglomerated material can easily cross the guide slope 342. The guide slope 342 will not block the agglomerated material from moving towards the side closer to the discharge port 12 on the filter screen 31 during this stroke, reducing the backflow of agglomerated material on the filter screen 31 during this stroke.

[0045] At the end of the second stroke and before the start of the first stroke, the adjusting mechanism 4 drives the wedge block 34 to passively reset from the second state to the first state. That is, before the end of the second stroke, when the fixed frame 32 and the filter screen 31 stop moving, the agglomerated material on the filter screen 31 will move away from the discharge port 12 on the filter screen 31 due to the inertia generated when it stops. At this time, the formation of the first state causes the wedge block 34 to protrude from the surface of the connecting plate 33 again. The blocking surface 341 of the wedge block 34 once again forms a block against the movement of the agglomerated material away from the discharge port 12, reducing the distance that the agglomerated material moves away from the discharge port 12, thus reducing the phenomenon of agglomerated material being carried back.

[0046] In this alternating process of the first and second strokes, the wood fibers (material) move towards the side closer to the discharge port. During this movement, the wood fibers fall off the filter screen 31, and the clumps of wood fibers (clumps of material) roll or slide unidirectionally on the filter screen 31 and are eventually discharged from the discharge port 12.

[0047] More specifically, the adjusting mechanism 4 includes a connecting shaft 41, a gear 42, and a rack 43. The gear 42 is rotatably connected to the connecting plate 33 via the connecting shaft 41. Both ends of the connecting shaft 41 extend into the fixed frame 32. The gear 42 is fixedly installed at both ends of the connecting shaft 41. The fixed frame 32 has a guide groove 321 inside. The rack 43 is installed in the guide groove 321 and forms a sliding guide engagement with the guide groove 321. The rack 43 meshes with the gear 42. The groove direction of the guide groove 321 is consistent with the length direction of the fixed frame 32. The guide groove 321 penetrates the fixed frame 32 and has openings at both ends. The connecting plate 33 also has a receiving groove 331 inside. The wedge block 34 is located in the receiving groove 331. Multiple sets of gears 42 and connecting shaft 41 are provided and installed on each wedge block 34 respectively.

[0048] In the first state, i.e., the initial state, the wedge block 34 is located at the upper opening of the receiving groove 331 and extends out of the receiving groove 331. At this time, one end of the rack 43 near the discharge port 12 extends out from the side opening of the guide groove 321, and the other end is located in the opening on the other side of the guide groove 321. When the fixed frame 32 moves during the first stroke, at the end of the first stroke, the movement of the fixed frame 32 causes the end of the rack 43 extending out of the guide groove 321 to contact the side wall of the hopper 1. The sidewalls force the rack 43 to retract into the guide groove 321, that is, the rack 43 slides in the guide groove 321 and drives the gear 42 to move synchronously. The gear 42 drives the wedge block 34 to rotate through the connecting shaft 41, so that the wedge block 34 rotates into the receiving groove 331. At this time, the wedge block 34 moves to the second state, and the guide slope 342 of the wedge block 34 is horizontal with the upper surface of the connecting plate 33 and the filter screen 31. At the same time, the other end of the rack 43 extends out from the other end opening of the guide groove 321.

[0049] Similarly, at the end of the second stroke, the movement of the fixed frame 32 causes the other end of the rack 43 to contact the side wall of the hopper 1, and under the contact of the side wall of the hopper 1, the rack 43 is forced to reset and move in the guide groove 321, and drive the wedge block 34 to reset and rotate, that is, to extend out of the receiving groove 331. At this time, the wedge block 34 reaches the first state to block the material from being carried back.

[0050] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
