Description

Technical Field

[0001] The present invention relates to the technical field related to sheet processing, and specifically to an intelligent blanking mechanism for a press metering belt. Background Art

[0002] As is known, in the process of preparing high-density boards, it is necessary to convey and control the materials in the silo to the paving device through transportation, and it is also necessary to accurately control the blanking amount from the silo, that is, the input amount conveyed to the paving device. Therefore, in the prior art, a metering belt or a belt scale is generally selected to achieve accurate output of the materials in the silo.

[0003] For example, in the patent with the publication number CN104444422B, the publication date of June 19, 2017, and the name "A Double-Weighting Metering Silo", it includes: a belt transportation mechanism; a silo erected on the belt transportation mechanism, an inlet is arranged at the position near the rear end along the transportation direction of the belt transportation mechanism at the top of the silo, and an outlet is arranged at the position near the front end along the transportation direction of the belt transportation mechanism at the bottom of the silo; a large-range weighing mechanism installed in the belt transportation mechanism and near the position where the vertical projection of the inlet of the silo on the belt transportation mechanism; and a small-range weighing mechanism installed in the belt transportation mechanism and behind the outlet of the silo; the belt transportation mechanism includes a frame, a driving roller, a driven roller, a belt and a driving device, the driving roller is axially arranged at the rear end of the frame, the driven roller is axially arranged at the front end of the frame, the belt is wound around the driving roller and the driven roller, and the driving device is installed on the frame and drives the driving roller to rotate; the silo is supported on the frame of the belt transportation mechanism through a silo frame, and a throwing device is arranged between the large-range weighing mechanism and the small-range weighing mechanism under the inlet of the silo in the silo, and the throwing device includes a throwing roller bracket, a plurality of throwing rollers and a driving motor for driving the plurality of throwing rollers to rotate.

[0004] In the prior art, the belt transportation mechanism in the above-mentioned authorized patent is a metering mechanism, and the intelligent blanking control of the materials in the silo can be realized through the belt transportation mechanism. However, since a part of the belt transportation mechanism is installed through the bottom of the silo, when the silo is filled with materials, the weight of all the materials in the entire silo will be applied to the belt transportation mechanism, that is, the belt transportation mechanism bears the weight of a large amount of materials in the entire silo, rather than bearing the materials sent out each time, resulting in increased wear and energy consumption of the belt transportation mechanism during operation, and there may also be a slipping phenomenon between the roller shaft and the belt in the belt transportation mechanism, thus affecting the blanking control of the materials.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the appended Figure 1 to the appended Figure 5 for a further detailed introduction to the present invention.

[0028] An embodiment of the present invention provides an intelligent blanking mechanism for a press metering belt, including a bin 1 and a metering and conveying mechanism 2. The metering and conveying mechanism 2 is installed through the inside of the bin 1. The metering and conveying mechanism 2 is used to send the material in the bin 1 out from the discharge port 11. A baffle 13 is also installed in the bin 1, and the baffle 13 is installed above the metering and conveying mechanism 2.

[0029] Specifically, the metering and conveying mechanism 2 is a metering belt, which can also be understood as a belt scale, or it can be understood that a weighing mechanism is installed in the conveyor belt for calculating the amount of material output when conveying the material. This is prior art and will not be elaborated. The baffle 13 is horizontally arranged above the metering and conveying mechanism 2. The baffle 13 divides the inside of the bin 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 is provided with holes. The first chamber 16 and the second chamber 17 are interconnected through the holes. When the material is conveyed from the feed port to the inside of the bin 1, the material in the bin 1 will first enter the first chamber 16. Among them, part of the material accumulates on the baffle 13, and the other part of the material enters the second chamber 17 through the holes and lands on the metering and conveying mechanism 2. As the material continuously enters the bin 1, the space in the first chamber 16 is gradually filled with the material, and the material in the first chamber 16 also continuously enters the second chamber 17 through the holes. At the same time, the metering and conveying mechanism 2 continuously sends the material in the second chamber 17 out from the feed port. Due to the design of the baffle 13, during the process of conveying the material by the metering and conveying mechanism 2, the metering and conveying mechanism 2 only needs to bear the weight of the material in the second chamber 17, and the material in the first chamber 16 is supported by the baffle 13. Therefore, under the action of the baffle 13, the weight of the material borne by the metering and conveying mechanism 2 during the material conveying process is reduced, and the problem of increased energy consumption caused by excessive load is also reduced.

[0030] In another embodiment of the present invention, further, a driving component 18 is installed on the side of the silo 1. The driving component 18 is connected to the baffle 13, and the driving component 18 is used to drive the baffle 13 to reciprocate horizontally in the silo 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 silo 1. The two ends of the baffle 13 respectively extend into the two groups of support blocks 14. A sliding groove 15 is formed inside the support blocks 14. The baffle 13 and the sliding groove 15 form a sliding guiding fit. In this embodiment, a driving component 18 is installed on the side of the silo 1. The driving component 18 can be a linear driving mechanism such as an electric push rod or a cylinder. The output shaft of the driving component 18 penetrates through the wall plate of the silo 1 to connect the baffle 13. During the feeding process of the metering and conveying mechanism 2, the driving component 18 drives the baffle 13 to reciprocate horizontally between the first chamber 16 and the second chamber 17, that is, to slide between the two groups of support blocks 14. Through this reciprocating movement, the movement speed of the material in the first chamber 16 towards the second chamber 17 can be accelerated, so that the material in the first chamber 16 can smoothly pass through the holes and enter the second chamber 17 and fall on the metering and conveying mechanism 2. The material is sent out from the discharge port 11 through the metering and conveying mechanism 2.

[0032] The raw material of the high-density board is wood fiber. In this embodiment, the material in the silo 1 is wood fiber. Because wood fiber has strong hygroscopicity and is prone to adhesion and agglomeration, when the agglomerated wood fiber enters the subsequent processes such as paving, it will cause problems such as uneven subsequent paving, uneven board density, decreased strength, and surface defects. Therefore, in order to prevent the agglomerated material in the silo 1 from being sent out from the discharge port 11, in another embodiment of the present invention, further, a filtering mechanism 3 for filtering the agglomerated material is installed inside the second chamber 17. The filtering mechanism 3 is installed directly below the baffle 13.

[0033] Specifically, the filtering mechanism 3 includes a filter screen 31 installed below the baffle 13. The filter screen 31 is connected to the baffle 13 through a connecting rod 36. When the baffle 13 reciprocates horizontally, the filter screen 31 is driven by the baffle 13 to move synchronously, that is, the filter screen 31 reciprocates horizontally in the second chamber 17, that is, swings left and right. When the material falls from the holes of the baffle 13, the material will fall on the filter screen 31. The filter screen 31 filters the agglomerates in the material. The fine wood fibers in the material pass through the filter screen 31 and fall on the metering and conveying mechanism 2, and the agglomerates are left on the filter screen 31. And through the left and right swing of the filter screen 31 in the second chamber 17, the phenomenon of material accumulation on the filter screen 31 can also be reduced, so that the filtering of the material can be carried out smoothly.

[0034] It should be noted that although there are holes in the baffle 13, since the aperture of the holes in the baffle 13 is relatively large and there is a large amount of accumulated material in the first chamber 16, 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, and does not have the effect of filtering the material in the first chamber 16. Moreover, since the amount of material in the first chamber 16 is large, it is also difficult for the baffle 13 and the holes on it to play a role in filtering the material.

[0035] In order to avoid the accumulation of agglomerated materials on the filter screen, the traditional method is to adopt an inclined filter screen so that the agglomerated materials are discharged along the inclined direction of the filter screen. However, the inclined filter screen will also discharge fine materials, that is, non-agglomerated wood fibers. In other words, it will cause some normal materials to be sent out, resulting in waste of this part of the materials. Therefore, in another embodiment, further, the filtering 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. Both ends of the connecting plate 33 are fixedly connected within the fixed frame 32. There are multiple groups of connecting plates 33, and the multiple groups of connecting plates 33 are arranged at equal intervals along the length direction of the fixed frame 32. The filter screen 31 is installed between two adjacent groups of connecting plates 33, and a wedge-shaped block 34 is installed on the upper surface of the connecting plate 33.

[0036] Specifically, there are multiple groups of connecting plates 33, and each group of connecting plates 33 is provided with a wedge-shaped block 34. The length directions of the connecting plate 33 and the wedge-shaped block 34 are the same as the width direction of the fixed frame 32. An adapter plate 35 is installed inside the second chamber 17, and the fixed frame 32 is placed on the adapter 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-shaped block 34 has an inclined guiding surface 342 and an arc-shaped blocking surface 341. As Figure 3 and Figure 4 shown, the blocking surface 341 is located on the left side surface of the wedge-shaped block 34, and the guiding surface 342 is located on the right side surface of the wedge-shaped block 34. A discharge port 12 for discharging agglomerated materials is provided on the left side surface of the second chamber 17, that is, the arc-shaped blocking surface 341 on the wedge-shaped block 34 is located on the side close to the discharge port 12. During 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 adapter plate 35. During the horizontal reciprocating movement of the filtering mechanism 3, in this embodiment, the movement stroke of the filtering mechanism 3 from right to left is recorded as the first stroke, and the first stroke is that the filtering mechanism 3 moves toward the side close to the discharge port 12. The movement stroke from left to right is the second stroke, and the second stroke is that the filter screen 31 mechanism moves away from the side of the discharge port 12;

[0037] In the first stroke, the fixed frame 32 moves in the second chamber 17 towards the side closer to the discharge port 12, driving 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 towards the side closer to the discharge port 12, and the arc-shaped blocking surface 341 of the wedge block 34 provides a strong block, the material (especially the agglomerated part with a large frictional force with the mesh surface) is pushed by the arc-shaped blocking surface 341 of the wedge block 34 and moves a certain distance towards the side closer to the discharge port 12 along with the filter screen 31;

[0038] In the second stroke, the fixed frame 32 moves in the second chamber 17 towards the side away from the discharge port 12, driving the filter screen 31 and the wedge block 34 to move synchronously. At this time, the material on the filter screen 31 tends to maintain its current position or move less due to its own gravity and inertia. As the wedge block 34 moves, the material moves onto the guiding inclined surface 342 due to inertia, that is, relative movement occurs between the guiding inclined surface 342 and the material. The guiding inclined surface 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 towards the side away from the discharge port 12. When the material falls back onto the filter screen 31 again, the material is closer to the discharge port 12 on the filter screen 31 than its initial position. In the subsequent first stroke, it is more convenient for the wedge block 34 to move the agglomerated material in the material towards the side closer to the discharge port 12. Repeating this process in sequence can continuously move the agglomerated material towards the discharge port 12; To ensure that the agglomerated material can cross the guiding inclined surface 342 during the above process, the speed of the second stroke can be made faster. Such an instantaneous acceleration can ensure relative movement between the agglomerated material and the guiding inclined surface 342.

[0039] In summary, the wedge block 34 forms a one-way structure on the connecting plate 33 and the filter screen 31, that is, in the first stroke, due to the slow movement speed of the fixed frame 32 and the block of the arc-shaped blocking surface 341 on the wedge block 34, the material will remain relatively stationary with respect to the filter screen 31. The movement of the filter screen 31 towards the side closer to the discharge port 12 will drive the material on it to move synchronously. In the second stroke, the movement speed of the fixed frame is faster and the material remains stationary. At this time, the filter screen 31 moves towards the side away from the discharge port, and relative movement occurs between the material and the filter screen 31. The material moves a certain distance towards the side closer to the discharge port 12 on the filter screen 31. Therefore, under the combination of the first stroke and the second stroke, the wood fibers fall from the filter screen 31 during the movement, the agglomerated wood fibers move towards the side closer to the discharge port 12 on the filter screen 31, and finally are discharged from the discharge port 12. At this time, they can be collected by an external collection device.

[0040] In the above embodiment, in the second stroke, the material will move onto the guiding inclined surface 342 due to inertia. Since the guiding inclined surface 342 has an inclined gradient, to a certain extent, this inclined gradient also blocks the movement of the material on the filter screen 31 towards the discharge port 12 side. Therefore, in another embodiment of the present invention, further, the wedge-shaped block 34 includes a first state and a second state. In the first state, the wedge-shaped block 34 is located on the surface of the connecting plate 33, and in the second state, the wedge-shaped block 34 is located inside the connecting plate 33.

[0041] Specifically, the first state of the wedge-shaped block 34 is its natural state when it protrudes from the connecting plate 33. In the second state, the entire wedge-shaped block 34 shrinks into the connecting plate 33. At this time, the guiding inclined surface 342 of the wedge-shaped block 34 and the filtering surface of the filter screen 31 are on the same horizontal plane, which can reduce the resistance to the movement of the material onto the guiding inclined surface 342. An adjusting mechanism 4 is installed in the bin 1, and the adjusting mechanism 4 is used to adjust the wedge-shaped block 34 to move from the first state to the second state.

[0042] More specifically, in the first stroke, the wedge-shaped block 34 remains in the first state, that is, the wedge-shaped block 34 protrudes from the surface of the connecting plate 33. The filter screen 31 and the wedge-shaped block 34 thereon move synchronously towards the side close to the discharge port 12. At this time, the agglomerated material on the filter screen 31 has a tendency to move towards the side away from the discharge port 12. Due to the protrusion of the wedge-shaped block 34 from the connecting plate 33 in the first state, under the blockage of the arc-shaped blocking surface 341 of the wedge-shaped block 34, the material will move synchronously with the filter screen 31 towards the side close to the discharge port 12 for a certain distance. It can be understood that the blocking surface 341 pushes the material towards the side close 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-shaped block 34 to passively switch from the first state to the second state. That is to say, before the fixed frame 32 and the filter screen 31 etc. stop moving before the end of the first stroke, the agglomerated material on the filter screen 31 will move towards the side close to the discharge port 12 on the filter screen 31 due to the inertia generated when stopping. At this time, the formation of the second state, that is, the disappearance of the guiding inclined surface 342, can prevent the inclined gradient of the guiding inclined surface 342 from blocking the inertial movement of the agglomerated material, and increases the moving distance of the agglomerated material towards the discharge port 12 side.

[0044] In the second stroke, the wedge block 34 remains in the second state. Since the filter screen 31 follows the fixed frame 32 at a relatively fast moving speed, the agglomerated material on the filter screen 31 has a tendency to move towards the side close to the discharge port 12. It can be understood that the material remains stationary, the filter screen 31 moves below the material, and relative movement is generated between the material and the filter screen 31. And after the guiding inclined surface 342 and the mesh surface of the filter screen 31 are horizontal, the agglomerated material can easily cross the guiding inclined surface 342, and the guiding inclined surface 342 will not block the tendency of the agglomerated material on the filter screen 31 to move towards the side close to the discharge port 12 in this stroke, reducing the backhaul of the agglomerated material on the filter screen 31 caused by the movement of the filter screen 31 in 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 to say, 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 towards the side away from the discharge port 12 on the filter screen 31 due to the inertia generated when stopping. 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, and the blocking surface 341 of the wedge block 34 constitutes a block to the movement of the agglomerated material towards the side away from the discharge port 12 again, reducing the distance of the agglomerated material moving towards the side away from the discharge port 12, that is, reducing the phenomenon of backhaul of the agglomerated material.

[0046] In this way, in the continuous alternation process of the first stroke and the second stroke, the whole of the wood fiber (material) moves towards the side close to the discharge port, and the wood fiber falls from the filter screen 31 during the movement. The agglomerated wood fiber (agglomerated material) rolls or slides unidirectionally on the filter screen 31 and finally is discharged from the discharge port 12.

[0047] More specifically, the adjusting mechanism 4 includes a coupling shaft 41, a gear 42 and a rack 43. The gear 42 is rotatably connected to the connecting plate 33 through the coupling shaft 41. Both ends of the coupling shaft 41 extend into the fixed frame 32. The gear 42 is fixedly installed at both ends of the coupling shaft 41. A guiding groove 321 is formed inside the fixed frame 32. The rack 43 is installed in the guiding groove 321 and forms a sliding guiding fit with the guiding groove 321. The rack 43 meshes with the gear 42. The groove direction of the guiding groove 321 is consistent with the length direction of the fixed frame 32. The guiding groove 321 penetrates the fixed frame 32 and both ends are provided with openings. A receiving groove 331 is also formed inside the connecting plate 33. The wedge block 34 is located in the receiving groove 331. There are multiple groups of the gear 42 and the coupling shaft 41, which are respectively installed on each wedge block 34;

[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 close to the discharge port 12 extends out from the side opening of the guiding groove 321, and the other end is located in the opening on the other side in the guiding groove 321. When the fixed frame 32 moves in the first stroke at this time and 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 guiding groove 321 to contact the side wall of the silo 1. Under the resistance of the side wall of the silo 1, the rack 43 is forced to contract into the guiding groove 321, that is, the rack 43 slides in the guiding groove 321 and drives the gear 42 to move synchronously. The gear 42 drives the wedge block 34 to rotate through the coupling 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 guiding inclined surface 342 of the wedge block 34 is horizontal with the upper surfaces of the connecting plate 33 and the filter net 31. At the same time, the other end of the rack 43 extends out from the other end opening of the guiding 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 silo 1, and under the resistance of the side wall of the silo 1, the rack 43 is forced to reset and move in the guiding groove 321, and drives 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 realize the blocking of the material backhaul.

[0050] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
