DETAILED DESCRIPTION

[0031] Embodiment 1, as Figure 1-Figure 8 As shown, the present embodiment provides a conveying device for fiberboard processing, which includes a frame 1 and a stacking support mechanism.

[0032] The frame 1 is horizontally provided with a conveying mechanism and a limiting mechanism, and the limiting mechanism includes two limiting plates 20 symmetrically distributed along a direction perpendicular to the conveying direction and an adjusting assembly for adjusting the distance between the two limiting plates 20. According to the width of the fiberboard to be conveyed and stacked, the distance between the two limiting plates 20 is adjusted by the adjusting assembly, so that the two sides of the fiberboard in the width direction are attached to the two limiting plates 20 for conveying, thereby improving the regularity of conveying. The limiting plate 20 is bent outward at one end close to the conveying starting point of the conveying mechanism, thereby playing a guiding role, so that the fiberboard is conveniently conveyed between the two limiting plates 20 by the conveying mechanism.

[0033] like Figure 1As shown, the conveying mechanism includes a plurality of conveying roller groups rotatably arranged on a frame 1, a plurality of second intermediate gears 5 rotatably arranged on the frame 1 and linking the plurality of conveying roller groups, and a motor 2 for driving a group of conveying roller groups to rotate. The conveying roller group includes a mounting shaft rotatably arranged on the frame 1, and a second gear 3 and a conveying roller 4 coaxially arranged on the mounting shaft. The motor 2 is arranged on the frame 1 and can drive a mounting shaft to rotate, and the mounting shaft drives the second gear 3 and the conveying roller 4 to rotate. The two second gears 3 in two adjacent conveying roller groups are meshed and connected with the second intermediate gear 5, and the second intermediate gear 5 is used for reversing. The second gear 3 drives the adjacent second gear 3 to rotate through the second intermediate gear 5, and the adjacent second gear 3 drives the conveying roller 4 to rotate through the corresponding mounting shaft. Similarly, the synchronous rotation of all conveying rollers 4 can be achieved, and the fiberboard can be smoothly conveyed.

[0034] like Figure 1 and Figure 3 As shown, the second gears 3 are arranged at both ends of the terminal conveying roller 4 of the conveying mechanism, that is, a second gear 3 is arranged at each end of the conveying roller 4 at the conveying end point of the conveying mechanism.

[0035] like Figure 1 and Figure 2 As shown, the adjustment assembly includes a bidirectional screw rod 22 rotatably arranged on the frame 1, a guide rod 23 arranged on the frame 1 and parallel to the bidirectional screw rod 22, two first movable plates 24 threadedly connected to the bidirectional screw rod 22 and symmetrically distributed, two second movable plates 25 slidably connected to the guide rod 23 and symmetrically distributed, and a crank 21 connected to one end of the bidirectional screw rod 22. The bidirectional screw rod 22 has a first threaded portion and a second threaded portion with opposite thread rotation directions, and the two first movable plates 24 are respectively threadedly connected to the first threaded portion and the second threaded portion. Each limit plate 20 is connected to a first movable plate 24 and a second movable plate 25. By rotating the crank 21, the bidirectional screw rod 22 can be driven to rotate, and the bidirectional screw rod 22 drives the two first movable plates 24 to move toward or away from each other, thereby realizing the movement of the two limit plates 20 toward or away from each other, and the two limit plates 20 are guided by the sliding of the two second movable plates 25 on the guide rod 23, and the spacing between the two limit plates 20 can be adjusted in the width direction of the conveying mechanism.

[0036] like Figure 3-Figure 6As shown, the stacking support mechanism includes a support seat 45, several groups of support mechanisms, a support plate 26, a plurality of pallets 27 spaced apart on the top of the support plate 26, and two groups of symmetrically distributed conveying and lowering mechanisms. The plurality of pallets 27 are spaced apart, and the fiberboards are stacked and palletized on the plurality of pallets 27. When it is necessary to remove the stacked multi-layer fiberboards, if a forklift is used for unloading, it is convenient to insert the fork from the space between the plurality of pallets 27. The support mechanism includes a guide cylinder 29 disposed on the support seat 45, a vertical rod 28 vertically damped and slidably disposed on the upper part of the guide cylinder 29, and a first spring 30 sleeved on the outer periphery of the vertical rod 28 and connected to the support plate 26 and the support seat 45 at both ends, respectively. The support plate 26 is horizontally disposed on the top of the vertical rod 28. The compression deformation of the first spring 30 is proportional to the weight of the fiberboard. The more layers of fiberboard are stacked, the heavier the total weight of the fiberboard is, the longer the first spring 30 is compressed, the longer the distance the vertical rod 28 extends downward into the guide cylinder 29, and the lower the height of the support plate 26 and the support platform 27. Therefore, the fiberboards can be stacked layer by layer, and each time a fiberboard is stacked at the top, the remaining fiberboards below will move downward a certain distance. Because the vertical rod 28 and the guide cylinder 29 are connected by a damping sliding connection, the first spring 30 will not have continuous elastic oscillation.

[0037] The conveying and lowering mechanism includes two groups of symmetrically distributed conveying and lowering components, a linkage component that drives the conveying and lowering components to connect with the conveying mechanism, and a switching mechanism for driving the two groups of conveying and lowering components to move toward or away from each other. When the switching mechanism drives the two groups of conveying and lowering components to move away from each other to the outside of the two limit plates 20, that is, when the conveying and lowering components no longer support and convey the fiberboard, the fiberboard will fall from the two groups of conveying and lowering components onto the support platform 27 or onto the fiberboard that has fallen previously.

[0038] like Figure 3-Figure 6As shown, the conveying lowering assembly includes a plurality of lowering roller assemblies arranged horizontally side by side, and the lowering roller assembly includes a wheel frame 8 arranged on a frame 1, two rollers 9 rotatably arranged on the wheel frame 8 and symmetrically distributed, a first gear 7 located between the two rollers 9 and in rolling contact with both rollers 9, a sliding shaft 10 and a key 11 slidingly arranged on the first gear 7, and a lowering roller 12 coaxially arranged on the sliding shaft 10, wherein the sliding shaft 10 has a first keyway, the first gear 7 has a second keyway, the key 11 is arranged at the first keyway, and is slidably connected to the first gear 7 through the second keyway. The first gear 7 can not only realize the rotation of the sliding shaft 10, the key 11 and the lowering roller 12, but also guide the sliding shaft 10 and the key 11, so that the lowering roller 12 moves outward and inward during rotation. The lowering roller 12 is lower than the limit plate 20, and the distance between the top of the lowering roller 12 and the bottom of the limit plate 20 is less than the thickness of the fiberboard. When the lowering roller 12 moves to the outside of the limit plate 20, the fiberboard is blocked by the limit plate 20 and will not be dragged out from between the two limit plates 20. When the first gear 7 rotates, it is limited by the two rollers 9, and the first gear 7 rotates at a determined position.

[0039] like Figure 3-Figure 5 As shown, the linkage assembly includes a plurality of first intermediate gears 6 that are rotatably arranged on the frame 1 and link the plurality of lowering roller assemblies. The second gears 3 at both ends of the terminal conveying roller 4 are respectively meshed and connected with the two first intermediate gears 6 of the linkage assembly. The two first gears 7 in the two adjacent lowering roller assemblies are both meshed and connected with the first intermediate gears 6. Then, the second gear 3 can first drive the adjacent first intermediate gears 6 to rotate. The first intermediate gear 6 drives the adjacent first gear 7 to rotate. The first gear 7 drives the sliding shaft 10 to rotate through the key 11. The first gear 7 drives the adjacent other first gear 7 to rotate through the first intermediate gear 6 on the other side, thereby realizing the synchronous rotation of the plurality of sliding shafts 10, and then realizing the synchronous rotation of the plurality of lowering rollers 12. The fiberboard is conveyed by the plurality of lowering rollers 12. The second gear 3 has the same size as the first gear 7, so the rotation speeds of the conveying roller 4 and the lowering roller 12 are equal, and a smooth connection and conveying can be performed.

[0040] like Figure 3 and Figure 4As shown, the switching mechanism includes two groups of connecting components and a switching component for driving the two groups of connecting components to move in opposite directions. The connecting components include a mobile frame 13 for rotatably mounting a plurality of lowering rollers 12 in the same group of conveying and lowering components, a horizontally distributed connecting column 14 connected to the mobile frame 13 at one end, and a horizontally distributed rack 15 connected to the other end of the connecting column 14. The two groups of connecting components correspond to the two groups of conveying and lowering components respectively, and a plurality of lowering rollers 12 in the same group of conveying and lowering components are rotatably mounted on each of the mobile frames 13. The switching component includes a third intermediate gear 19 rotatably mounted on the frame 1 and simultaneously meshed with two racks 15 in the two groups of connecting components, a connecting plate 18 connected to one rack 15, a first telescopic mechanism 17 arranged on the frame 1 and driving the connecting plate 18 to move horizontally, and two guide plates 16 arranged on the frame 1 and respectively for the two connecting columns 14 to slide horizontally. The first telescopic mechanism 17 can be an electric push rod, a hydraulic cylinder or an air cylinder, which can drive the connecting plate 18 to move by telescoping, and the connecting plate 18 drives a rack 15 to move, and the rack 15 drives another rack 15 to move through the third intermediate gear 19. The moving directions of the two racks 15 are opposite, and the two racks 15 drive the two connecting columns 14 to move respectively. The two guide plates 16 guide the two connecting columns 14 to move horizontally respectively, and the two connecting columns 14 drive the two moving frames 13 to move respectively. The moving directions of the two moving frames 13 are opposite, so the moving directions of the two groups of conveying and lowering components are opposite, and the moving directions of the two rows of lowering rollers 12 are opposite. When the inner end of the lowering roller 12 moves outward to the outer side of the limit plate 20, the fiberboard on the lowering roller 12 will fall down for stacking and palletizing; when the inner end of the lowering roller 12 moves inward again to the lower side of the inner side of the two limit plates 20, it can be reused for the subsequent conveying of the fiberboard and is ready for the subsequent lowering of the fiberboard.

[0041] like Figure 6 As shown, a second telescopic mechanism 47 is horizontally arranged on the frame 1, and a baffle 46 that can block the top of the support plate 26 is connected to the movable end of the second telescopic mechanism 47. The second telescopic mechanism 47 can adopt an electric push rod, a hydraulic cylinder or a cylinder, and can drive the baffle 46 to move horizontally by telescoping. When the fiberboard reaches the target number of stacking layers and height, the height of the baffle 46 is between the height of the top surface of the support plate 26 and the top surface of the pallet 27, that is, the baffle 46 can be extended to the top of the support plate 26 under the drive of the second telescopic mechanism 47, and is located between the intervals of the pallet 27. Then, the fork of the forklift is inserted into the intervals between the multiple pallets 27 to lift up the multi-layer stacked fiberboard. When the first spring 30 pushes the support plate 26 up to abut against the baffle 46, the fork can move the lifted fiberboard outward to complete a stacking and transportation process. Then, the second telescopic mechanism 47 moves the baffle plate 46 outward to release the blocking of the support plate 26, and the first spring 30 pushes the support plate 26 upward to prepare for the next stacking process.

[0042] The conveying method of the conveying device for fiberboard processing comprises the following steps:

[0043] S1, conveying the fiberboard through a conveying mechanism;

[0044] S2, the fiberboard is limited by two limit plates 20 during the conveying process, and the fiberboard is conveyed horizontally and the conveying is relatively regular;

[0045] S3, the fiberboard is conveyed to the lowering rollers 12 on the two lowering roller assemblies. During the conveying process of the fiberboard, the two lowering roller assemblies drive the two rows of lowering rollers 12 in the two lowering roller assemblies to move away from each other through the switching mechanism. When the lowering rollers 12 move to the outside of the limit plate 20, there is no structure under the fiberboard to support it. The fiberboard falls from between the two limit plates 20 onto the support platform 27. This is the first lowering of the fiberboard, and the first spring 30 is compressed.

[0046] S4, the conveying mechanism continues to operate, and subsequent fiberboards are stacked and fall onto the previous fiberboard in sequence, the total weight of the multiple fiberboards gradually increases, the compression degree of the first spring 30 gradually increases, and the length gradually shortens;

[0047] S5, when the number of fiberboards stacked and palletized reaches the requirement, the plurality of fiberboards stacked and palletized are removed from the pallet 27. Then, the next stacking and palletizing and taking-out cycle is prepared.

[0048] This embodiment can automatically stack and palletize multiple fiberboards by dropping them during transportation, thereby improving the palletizing efficiency and the palletizing height. The lowering roller 12 can be used for both the transportation of fiberboards and the release of the support for the fiberboards by moving outward, so that the fiberboards fall due to their own gravity, one fiberboard at a time. As the conveying mechanism continuously transports multiple fiberboards at intervals, the lowering roller 12 moves back and forth inward and outward during the rotation process, and the moving distance is relatively short, so that multiple fiberboards can be lowered in sequence to achieve the stacking and palletizing of multiple fiberboards.

[0049] In addition, a positioning plate can be vertically arranged on the frame 1, and the positioning plate is located outside the farthest lowering roller 12. A pressure sensor and a controller are arranged on the surface of the positioning plate facing the lowering roller 12. The pressure sensor and the controller are connected in communication, and the controller is connected in control with the first telescopic mechanism 17. When the fiberboard is conveyed by the lowering roller 12 to abut against the pressure sensor, the pressure sensor detects the pressure and sends a signal to the controller, and the controller controls the first telescopic mechanism 17 to move, so as to realize the separation of the two rows of lowering rollers 12 and drop the fiberboard. At this time, multiple fiberboards fall at the same position, which makes it easier to stack and stack them neatly.

[0050] Embodiment 2, as Figure 1-Figure 8As shown, the present embodiment proposes a conveying device for fiberboard processing. Compared with the first embodiment, in the present embodiment, the guide cylinder 29 includes a first vertical section, a first horizontal section, a second vertical section and a second horizontal section which are connected in sequence. The vertical rod 28 is provided with damping sliding on the first vertical section. The cross-sectional dimension of the inner channel of the first vertical section is larger than the cross-sectional dimension of the inner channel of the second horizontal section. The second horizontal section is provided with a cross bar 32 for damping sliding. After the vertical rod 28 slides downward for a certain distance, the distance that the cross bar 32 slides outward is farther than the distance that the vertical rod 28 slides. The bottom of the second horizontal section is connected with a venting end 291. The opening dimension of the venting end 291 is smaller than the opening dimension of the outer end of the second horizontal section. The air pressed by the downward movement of the vertical rod 28 is preferentially used to push the cross bar 32 outward. The outward movement is the outward movement of the cross bar 32 relative to the second horizontal section of the guide cylinder 29, and is also the movement of the cross bar 32 toward the fiberboard direction. The outer end of the cross bar 32 is connected to a vertically arranged push plate 31. When the cross bar 32 moves outward, the push plate 31 is driven to move outward. The two push plates 31 push from both sides of the fiberboard to align the two sides of the multi-layer fiberboard. A bracket 34 is provided on the frame 1. A second spring 33 sleeved on the outer periphery of the cross bar 32 and the second horizontal section is connected between the bracket 34 and the push plate 31. Because the cross bar 32 and the second horizontal section are connected by sliding damping, the second spring 33 will not have elastic oscillation. A blocking component capable of blocking the ventilation end 291 is provided on the push plate 31, and a guide component for switching the blocking component to block or release the ventilation end 291 is provided on the frame 1.

[0051] When the push plate 31 moves outward and pushes the fiberboard, the second spring 33 is stretched and stores elastic potential energy. At the initial position where the push plate 31 starts to move outward, the blocking assembly blocks the ventilation end 291. When the fiberboard falls onto the support platform 27, the vertical rod 28 moves down suddenly due to the impact force. The air in the guide cylinder 29 pressed by the vertical rod 28 is mainly used for the outward movement of the cross bar 32. Until the push plate 31 moves outward to the limit position, the blocking assembly releases the blocking of the ventilation end 291. At this time, the outside air begins to enter the guide cylinder 29 through the ventilation end 291, the second spring 33 pulls the push plate 31 to move toward the guide cylinder 29, and the cross bar 32 slides inward at the second horizontal section of the guide cylinder 29 and keeps the ventilation of the ventilation end 291. Until the cross bar 32 moves inward to the limit position, the blocking assembly blocks the ventilation end 291 again, and the push plate 31 is reset. When the two push plates 31 are reset, the distance between the two push plates 31 is greater than the width of the fiberboard. When the support platform 27 is impacted by the falling fiberboard next time, the vertical rod 28 continues to move downward, and the push plate 31 continues to move outward to align the fiberboard and move inward to reset. Each time a fiberboard falls, the pushing process is performed.

[0052] like Figure 7As shown, the blocking assembly includes a guide seat 35 provided on the push plate 31 and having a strip hole, a slide rail 36 provided below the guide seat 35, a threaded knob 40 penetrating the strip hole and threadedly connected to the slide rail 36, a slider 37 slidably provided on the slide rail 36, a blocking strip 38 connected to the slider 37, and a guide wheel 39 rotatably provided at the end of the blocking strip 38. The slide rail 36 is located below the guide seat 35 and the lateral position is adjustable, so as to adjust the distance from the outer end of the blocking strip 38 to the ventilation end 291, so as to be suitable for the blocking state and the unblocking state at different distances. When adjusting, the threaded knob 40 is loosened, and the slide rail 36 is moved to the target position. The threaded knob 40 moves along the strip hole during this process, and then the threaded knob 40 is tightened, and the threaded knob 40 abuts against the guide seat 35, so that the slide rail 36 is installed in place. In order to prevent the slider 37 from falling off the slide rail 36, a blocking platform can also be detachably installed at both ends of the slide rail 36 to limit the range of motion of the slider 37.

[0053] like Figure 6-Figure 8 As shown, the guide assembly includes a bracket 41 arranged on the bracket 34, a first guide frame 42 arranged on the bracket 41, a second guide frame 43 horizontally slidably connected to the first guide frame 42, and a bolt 44 connecting the first guide frame 42 and the second guide frame 43. A parallelogram guide channel for the guide wheel 39 to roll against the edge is formed between the first guide frame 42 and the second guide frame 43, and the adjacent two angles of the guide channel are respectively an obtuse angle and an acute angle, that is, the guide channel is not a square and a rectangle. When the guide wheel 39 is respectively at the two acute angles of the guide channel, the blocking strip 38 is in two states of the upper surface blocking the ventilation end 291 and the unblocked ventilation end 291. The two obtuse angles of the guide channel can also be rounded so that the guide wheel 39 moves more smoothly along the outer peripheral surface of the guide channel. In the initial state, the guide wheel 39 is at the acute angle of the local guide channel on the first guide frame 42, and the blocking strip 38 blocks the ventilation end 291.

[0054] When the push plate 31 moves outward to align the fiberboard, the guide wheel 39 first moves in a straight line along the first guide frame 42 toward the second guide frame 43, and the position of the slider 37 on the slide rail 36 remains unchanged. When the guide wheel 39 moves to the obtuse angle of the local guide channel of the second guide frame 43, the guide wheel 39 will continue to move in the inclined direction. During the movement, the slider 37 slides on the slide rail 36. When the guide wheel 39 moves to the acute angle of the local guide channel on the second guide frame 43, the sealing strip 38 moves away from the bottom end of the ventilation end 291 to release the blockage of the ventilation end 291. When the push plate 31 is pulled by the second spring 33, the guide wheel 39 first moves from the acute angle of the local guide channel of the second guide frame 43 to the obtuse angle of the local guide channel of the first guide frame 42, and then moves from the obtuse angle along the inclined direction to the initial position, that is, the acute angle of the local guide channel of the first guide frame 42. During the movement, the ventilation end 291 is not blocked, and the outside air can enter the guide cylinder 29 through the ventilation end 291. After the guide wheel 39 moves to the initial position, the sealing strip 38 re-blocks the ventilation end 291.

[0055] The first guide frame 42 includes an integrally formed first guide platform 421 and a first limiting platform 422. The first guide platform 421 has a first partial guide groove with one end open. The outer peripheral surface of the first partial guide groove is used to guide the guide wheel 39. The first limiting platform 422 is arranged in the middle of the open end of the first partial guide groove to limit the range of movement of the guide wheel 39. The second guide frame 43 includes an integrally formed second guide platform 431, a second limiting platform 432 and a sliding plate 433. The second guide platform 431 has a second partial guide groove with one end open. The outer peripheral surface of the second partial guide groove is used to guide the guide wheel 39. The second limiting platform 432 is arranged in the middle of the open end of the second partial guide groove and extends outward. The second limiting platform 432 is slidably connected to the first limiting platform 422. The first limiting platform 422 and the second limiting platform 432 work together to limit the range of movement of the guide wheel 39. The first guide platform 421 has a slide groove slidably connected to the slide plate 433, and the slide plate 433 can be used to guide the guide wheel 39 when it moves. The bolt 44 is threadedly connected to the first guide platform 421 and the end thereof abuts against the slide plate 433. After adjusting the relative positions of the first guide frame 42 and the second guide frame 43, the two parts are connected by the bolt 44.

[0056] In this embodiment, by adjusting the relative positions of the first guide frame 42 and the second guide frame 43, the side length of the parallelogram guide channel can be adjusted, thereby adjusting the size of the guide channel, and then adjusting the limit distance of movement of the push plate 31, so as to push and align fiberboards of different widths. At the same time, it is also necessary to adjust the two limit plates 20 in place in advance to be suitable for guiding fiberboards of corresponding widths.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
