Description

Technical Field

[0001] The invention relates to the technical field of plate stacking, and in particular to a processing device for producing fiberboards. Background Art

[0002] Fiberboard, also known as density board, is a man-made board made of wood fiber or other plant fiber as raw materials, with urea-formaldehyde resin or other suitable adhesives applied. Fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, and not easy to crack. The manufacture of wood fiberboard requires a series of procedures such as cutting, steaming, hot grinding, drying, and pressing. After the final product is made, for the convenience of transportation and management, single fiberboards need to be stacked into stacks. At present, stacking work is usually done manually in small enterprises, and large enterprises use automatic assisted stacking devices. The stacking device is set at the end of the conveyor line. The fiberboard moves to the stacking position under its inertia to complete the stacking. This type of stacking device includes a lifter. At the beginning, the lifter rises to the same height as the conveyor line. As the fiberboard is slowly stacked, the lifter slowly descends to a level that can better receive the next stack of fiberboards.

[0003] The Chinese patent document with authorization announcement number CN114906597B discloses a sheet material stacker, comprising a base, a frame is installed on the base along the vertical direction, a conveying structure is fixed on the upper part of the frame, and also comprises a unloading structure, the unloading structure is arranged at the discharge end of the conveying structure, and is used to unload the sheet material; the unloading structure comprises a connecting frame, and the connecting frame is provided with the discharge end of the conveying structure along the length direction of the conveying structure; the unloading guide frame is arranged at the edge of the connecting frame at one end away from the conveying structure; the unloading of the sheet material is supported by adjusting the inclination angle of the top surface of the unloading guide frame; at least two of the handles are rotatably connected to the two sides of the connecting frame, and the rotating shaft of the handle is perpendicular to the length direction of the conveying structure; the toggle member is fixed on the top end of the handle; the toggle member unloads the sheet material under the drive of the handle; the sheet material stacker can adjust its own structure so that the sheet material can be unloaded smoothly.

[0004] During use of the existing stacking device, one end of the next fiberboard first contacts the previous fiberboard, and then slides along the upper surface of the previous fiberboard, which will scratch the upper surface of the previous fiberboard and wear the side of the next fiberboard that contacts the previous fiberboard, affecting product quality. Summary of the invention

[0005] The present invention provides a processing device for fiberboard production, aiming to solve the problem of wear caused by relative friction during fiberboard stacking in the related art.

[0006] A processing device for fiberboard production comprises a conveying mechanism, a cutting mechanism and a stacking mechanism, wherein the cutting mechanism and the stacking mechanism are respectively arranged at two ends of the conveying mechanism, and also comprises a feeding mechanism arranged at the rear end of the conveying mechanism, wherein the feeding mechanism comprises two telescopic rods symmetrically installed at the rear end of the conveying mechanism, the front end of the telescopic rod is installed on the conveying mechanism, a synchronization component for controlling the same elongation of the two telescopic rods is installed between the two telescopic rods, a reset component for restoring the telescopic rod to a contracted state is installed on the telescopic rod, a vertically arranged spring rod is installed at the telescopic end of the telescopic rod, a baffle plate abutting against the rear end surface of the fiberboard is installed on the piston rod of the spring rod, a tug wheel is installed below the baffle, and in the initial state, the tug wheel contacts the top fiberboard of the stacking mechanism, a support rod is installed on the bottom of the baffle plate in a horizontal sliding direction, and a control component is installed on the support rod, and when the tug wheel does not contact the fiberboard on the stacking mechanism, the spring rod extends, and the control component causes the support rod to separate from the supported fiberboard.

[0007] The effect is: in the initial state, the supporting surface of the support rod for supporting the fiberboard is lower than the bottom surface of the fiberboard on the feeding mechanism. When the tug wheel is not in contact with the fiberboard on the stacking mechanism, the gravity of the fiberboard on the support rod causes the spring rod to stretch, and the control component causes the support rod to move backward relative to the baffle, thereby allowing the support rod to separate from the supported fiberboard to complete the stacking.

[0008] Preferably, a mounting frame is fixedly mounted at the rear end of the conveying mechanism, and the front end of the telescopic rod is slidably mounted on the mounting frame, so that the distance between the two telescopic rods can be adjusted conveniently according to the thickness of the fiberboard.

[0009] Preferably, the synchronization component includes a telescopic connecting rod, and both ends of the telescopic connecting rod are respectively connected to the telescopic ends of the two telescopic rods, so that the two telescopic rods can be telescoped synchronously.

[0010] Preferably, the resetting assembly comprises an elastic belt, both ends of which are respectively connected to the telescopic connecting rod and the conveying mechanism, so as to facilitate resetting the telescopic rod, thereby automatically stacking the next fiberboard.

[0011] Preferably, the control assembly includes a slide seat which is slidably arranged on the rear side of the baffle plate, the slide seat is rotatably mounted on the sleeve of the spring rod, the slide seat is provided with an inclined groove, and the support rod is provided with a sliding block which is adapted to the inclined groove. When the tug wheel is out of contact with the fiberboard on the stacking mechanism, the gravity of the fiberboard on the support rod causes the spring rod to extend, and at the same time causes the sliding block to slide along the front inclined surface of the inclined groove, thereby causing the support rod to move toward the rear end until the support rod is separated from the supported fiberboard, and the fiberboard is then aligned and lowered.

[0012] Preferably, the groove width at the rear end of the inclined slide groove in the height direction is greater than the groove height at the front end in the height direction, and the groove height difference Δh between the rear end and the front end of the inclined slide groove in the height direction is greater than the thickness t of the fiberboard. After the support rod passes over the fallen fiberboard upward, it contacts the rear inclined surface of the inclined slide groove, thereby preventing the support rod from moving forward and applying pressure to the front end of the fiberboard.

[0013] Preferably, rollers are installed on the surface of the support rod for supporting the fiberboard.

[0014] Preferably, the front end of the tugboat does not exceed the plane where the front end surface of the baffle is located.

[0015] Preferably, the baffle is rotatably mounted on the telescopic end of the spring rod about the axis of the spring rod, and a fastener for fixing the baffle and the spring rod together is mounted on the baffle.

[0016] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0017] When the fiberboard on the conveying mechanism is fed to the lifting platform, the fiberboard first contacts the baffle plate, thereby pushing the baffle plate to move backward, thereby extending the telescopic rod. When the center of gravity of the fiberboard passes over the conveying mechanism, the rear end of the fiberboard drops, and the supporting rod supports the rear end bottom surface of the fiberboard. At the same time, the spring rod is stretched by the downward pulling force, and the tugwheel contacts the lifting platform / fiberboard below, thereby providing support for the rear end of the fiberboard and avoiding sliding friction between the fiberboard below and the fiberboard being stacked, thereby preventing the fiberboard from being damaged. The tugwheel then continues to move until the front end of the tugwheel exceeds the rear end surface of the lifting platform / bottom fiberboard. Due to the gravity of the fiberboard on the supporting rod, the spring rod is stretched, and the sliding block slides along the front inclined surface of the inclined slide groove, thereby moving the supporting rod to the rear end until the supporting rod is separated from the supported fiberboard, and the spring rod contracts, thereby causing the supporting rod to move forward relative to the baffle plate to reset, and the supported fiberboard falls on the lifting platform / fiberboard below, and the rear end surface of the fiberboard is flush with the rear end surface of the lifting platform, thereby completing the stacking.

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figure 1 and Figure 2 As shown, a processing device for fiberboard production includes: a conveying mechanism 1, a cutting mechanism 2, a feeding mechanism 4 and a stacking mechanism 3. The cutting mechanism 2 is arranged at the front end of the conveying mechanism 1, and is used to cut the fiberboard into segments evenly. The cut fiberboard is conveyed to the feeding mechanism 4 by the transportation mechanism, and the fiberboard is sent to the stacking mechanism 3 by the feeding mechanism 4 for stacking.

[0029] like Figure 1 , Figure 5 and Figure 6 As shown, the feeding mechanism 4 includes: a telescopic rod 41, a synchronization component 42, a reset component 43, a spring rod 44 and a supporting component. The number of the telescopic rods 41 is two. A mounting frame is fixedly installed at the rear end of the conveying mechanism 1. The front end of the telescopic rod 41 is slidably installed on the mounting frame. The distance between the two telescopic rods 41 is adjusted to adapt to plates of different widths. The synchronization component 42 and the reset component 43 are installed between the two telescopic rods 41 to control the synchronous extension and reset of the two telescopic rods 41.

[0030] There are two spring rods 44, which are composed of a sleeve, a piston rod and a tension spring arranged in the sleeve, and are vertically installed at the telescopic ends of the two telescopic rods 41 respectively. Two supporting assemblies are respectively installed at the bottom ends of the two spring rods 44 to support the rear end of the fiberboard.

[0031] The synchronization component 42 includes a telescopic connecting rod, and both ends of the telescopic connecting rod are respectively connected to the telescopic ends of the two telescopic rods 41, so that the two telescopic rods 41 are kept at the same telescopic amount.

[0032] The reset assembly 43 includes an elastic belt, the two ends of which are respectively connected to the telescopic connecting rod and the conveying mechanism 1. When the fiberboard is separated from the supporting assembly, the elastic belt contracts to move the telescopic connecting rod back, thereby shortening the two telescopic rods 41.

[0033] The supporting assembly includes a baffle 45, a supporting rod 47, a tug wheel 46 and a control assembly 48. The baffle 45 is fixedly mounted at the bottom end of the spring rod 44, the tug wheel 46 is mounted at the bottom of the baffle 45, and the front end of the tug wheel 46 does not exceed the plane where the front end surface of the baffle 45 is located. There are two supporting rods 47 that are connected and slidably mounted at the bottom of the baffle 45. In the initial state, the supporting surface of the supporting rod 47 for supporting the fiberboard is lower than the bottom surface of the fiberboard on the feeding mechanism 4, and a roller 471 is installed on the supporting surface of the supporting rod 47. When the tug wheel 46 is not in contact with the fiberboard on the stacking mechanism 3, the spring rod 44 is extended due to the gravity of the fiberboard on the supporting rod 47, and the control assembly 48 causes the supporting rod 47 to move backward relative to the baffle 45, thereby causing the supporting rod 47 to separate from the supported fiberboard.

[0034] like Figure 5 , Figure 6 and Figure 7 As shown, the control assembly 48 includes a slide seat 481 which is slidably arranged on the rear side of the baffle 45 through a guide groove, and the top end of the slide seat 481 is rotatably mounted on the sleeve of the spring rod 44 through a rotating ring. An inclined slide groove is provided on the slide seat 481, and the shape of the inclined slide groove is trapezoidal. The front inclined surface of the inclined slide groove is parallel to the rear inclined surface, and the top inclined surface is connected to the front inclined surface, and the top inclined surface gradually tilts downward from the front end to the rear end. A sliding block 482 is provided on the support rod 47 to abut against the inclined slide groove, and the inclined surface on the front side of the inclined slide groove abuts against the sliding block 482.

[0035] Assume that the diameter of the sliding block 482 is r, the distance between the front and rear inclined surfaces of the inclined slot in the vertical direction is Δh, and the thickness of the fiberboard is t, then r+t<Δh. In this way, when the tug 46 is out of contact with the fiberboard on the stacking mechanism 3, the gravity of the fiberboard on the supporting rod 47 causes the spring rod 44 to extend, and at the same time, the sliding block 482 slides along the front inclined surface of the inclined slot, so that the supporting rod 47 moves to the rear end until the supporting rod 47 is out of contact with the supported fiberboard (such as Figure 4 As shown), the spring rod 44 contracts, the sliding block 482 moves upward, and the support rod 47 passes over the fallen fiberboard and contacts the rear inclined surface of the inclined slide, thereby preventing the support rod 47 from moving forward and applying pressure to the front end of the fiberboard. Finally, the sliding block 482 abuts against the top inclined surface of the inclined slide, so that the support rod 47 moves forward relative to the baffle 45 to reset.

[0036] The stacking mechanism 3 includes a lifting platform and a lifting mechanism for controlling the lifting of the lifting platform. In the initial state, the top surface of the lifting platform is lower than the top surface of the conveyor belt of the conveying mechanism 1, and the minimum height difference between the two is a fiberboard thickness t. When the fiberboard detaches from the support rod 47 and falls onto the lifting platform, the lifting mechanism controls the lifting platform to descend to a height of a fiberboard thickness t.

[0037] Working principle: When the fiberboard on the conveying mechanism 1 is fed to the lifting platform, the fiberboard first abuts against the baffle 45, thereby pushing the baffle 45 to move backward, so that the telescopic rod 41 extends. When the center of gravity of the fiberboard passes over the conveying mechanism 1, the rear end of the fiberboard drops, and the support rod 47 supports the rear end bottom surface of the fiberboard. At the same time, the spring rod 44 is stretched by the downward pulling force, and the tug wheel 46 contacts the lifting platform / fiberboard below, thereby providing support for the rear end of the fiberboard (such as Figure 3 As shown), while avoiding sliding friction between the fiberboard below and the fiberboard being stacked, thereby preventing the fiberboard from being damaged, the tugboat 46 continues to move until the front end of the tugboat 46 exceeds the rear end face of the lifting platform / bottom fiberboard, the spring rod 44 is extended due to the gravity of the fiberboard on the support rod 47, and the sliding block 482 slides along the front inclined surface of the inclined slide slot, thereby moving the support rod 47 to the rear end until the support rod 47 is separated from the supported fiberboard, and the spring rod 44 contracts, thereby causing the support rod 47 to move forward relative to the baffle 45 to reset, and the supported fiberboard falls on the lifting platform / fiberboard below, and the rear end face of the fiberboard is flush with the rear end face of the lifting platform, thereby completing the stacking.

[0038] like Figure 1 and Figure 6 As shown, in order to adapt to the fiberboard with an inclined rear end, in another embodiment, the other structures are the same as the above embodiment, except that: the baffle 45 is rotatably mounted on the telescopic end of the spring rod 44 with the axis of the spring rod 44, and a fastener 451 for fixing the baffle 45 and the spring rod 44 together is installed on the baffle 45, and the telescopic connecting rod and the telescopic ends of the two telescopic rods 41 are also adjustably installed, by loosening the fastener 451, and then changing the angle between the telescopic connecting rod and the baffle 45 and the front-view reference plane, so that the two are parallel to the rear end surface of the fiberboard, and then tightening the fastener 451, so as to adapt.

[0039] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
