Description

TECHNICAL FIELD

[0001] The utility model belongs to timber processing technical field, especially relate to a wood base material push-avoiding loading device. BACKGROUND

[0002] Plywood, also known as a clamp plate, is one of the commonly used materials for furniture, and is a kind of artificial board. A group of veneers are usually assembled into a board by gluing with the wood grain direction of adjacent layers perpendicular to each other. The surface plate and the inner layer plate are symmetrically arranged on both sides of the center layer or the board core. The inner layer plate is also known as wood base material. The board blank is made by matching the wood grain direction of the glued veneers vertically and horizontally, and is pressed under heating conditions. The physical and mechanical properties of the vertical and horizontal directions are less different. Commonly used ones are three-ply board, five-ply board, etc. Plywood can improve the utilization rate of wood and is a major way to save wood.

[0003] The wood base material (wood board) often needs to be fed during processing. In view of the automation of feeding operation, the patent document with publication number CN109079918A discloses a wood board pushing and feeding machine, which comprises a feeding bottom plate, a feeding stand, a feeding lifting plate and a feeding assembly. The feeding lifting plate is in sliding cooperation with the feeding stand, and the feeding lifting plate is provided with a feeding lifting motor. The feeding assembly is arranged on the feeding lifting plate. The feeding assembly comprises a feeding roller mounting seat, a buffer guide column and a board limiting frame. The feeding roller mounting seat is matched with the feeding lifting plate through the buffer guide column. The feeding roller mounting seat is provided with a motor lead screw mechanism and a feeding push plate. The board limiting frame is arranged on the discharge side of the feeding roller mounting seat. The feeding assembly of the present application can automatically feed the stacked boards on the bottom plate backward. As the number of stacked boards decreases, the feeding lifting plate can also lower the height of the feeding assembly.

[0004] In the above-mentioned comparative document, the feeding assembly is located directly above the stacked boards. The existing wood base material is heavy. In order to pursue efficiency, the loading machinery such as crane, loader and forklift is usually used for stacking operation. The comparative document does not provide an avoiding mechanism, that is, the feeding assembly located directly above the stacked boards will affect the work of the loading machinery, resulting in that the above-mentioned equipment can only rely on manual stacking of boards from the side of the equipment, which is too time-consuming and laborious.

[0006] The above technical purpose of the utility model is realized by the following technical scheme:

[0008] Furthermore, in order to improve the pushing strength of the push plate and reduce the wear of the push plate, a block-shaped pushing ridge made of wear-resistant steel is fixed to the bottom of the push plate. The single-side thickness of the pushing ridge and the push plate connected to it is less than the thickness of the wooden base material required for the pusher.

[0009] Furthermore, in order to ensure that the push plate can reach the specified position each time and only push one wooden substrate each time, two sets of rod-shaped limit bars are fixed on the push plate, and the axis of the limit bars is parallel to the axis of the pusher hydraulic cylinder.

[0010] Furthermore, in order to prevent the wear-resistant pusher strips from damaging the wood substrate and to improve the smoothness of the pusher strips sliding on the wood substrate, the pusher strips are rotatably coupled with at least two sets of pulleys of roller structure via shafts.

[0011] Furthermore, in order to ensure that the pushing convex strip always exerts a continuous downward pressure on the wooden base material, the pushing convex strip can immediately move down to the side of the wooden base material when it reaches the appropriate position; an elastic component is provided on the telescopic rod of the deflection hydraulic cylinder, and the main body of the elastic component is a spring. The telescopic rod of the hydraulic cylinder is disconnected from it to form a concentric first telescopic rod and a second telescopic rod, and the first telescopic rod and the second telescopic rod are concentrically connected by a spring.

[0012] Furthermore, in order to prevent the spring from being over-pulled and causing its deformation to be unable to recover, and to prevent the spring from bending and shifting, the elastic component also includes: a sleeve and a limit ring.

[0014] Furthermore, in order to improve the connection strength between the base frame and the vertical frame and improve the anti-rolling ability of the vertical frame, the two sides of the vertical frame are connected and fixed to the base frame with reinforcing ribs.

[0017] ① An avoidance mechanism is provided so as not to affect the stacking operation of the loading equipment. By setting up the deflection hydraulic cylinder, the lifting platform is started to make the upper surface of the loading plate and the upper surface of the working platform flush, and then the deflection hydraulic cylinder is started to contract, and the deflection hydraulic cylinder drives the pushing hydraulic cylinder, the pushing plate, and the limiting bar to deflect as a whole around the vertical frame, reserving an avoidance space for stacking the wood base material, and then the wood base material to be processed is neatly stacked on the loading plate by a crane or a loader; then the deflection hydraulic cylinder is started to extend, and the deflection hydraulic cylinder drives the hydraulic cylinder, the pushing plate, and the limiting bar to deflect as a whole until the limiting bar is attached to the upper surface of the uppermost wood base material, and the pushing convex strip is located on the side of the wood base material.

[0018] ② The loading height can be maintained unchanged: through the establishment of the lifting platform, because the top layer of wood substrate is pushed away, the thickness of the existing wood substrate is not flush with the feeding position. At this time, the external controller starts the lifting platform again to drive the loading plate to move upward by the thickness of the wood substrate. Then repeat the above action to complete the feeding operation at the same loading height. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Example:

[0027] See also Figure 1-Figure 5 , this utility model provides a technical solution:

[0028] A wood-based material pushing and avoiding feeding device comprises: a base frame 1, a vertical frame 2, and a working platform 3; the working platform 3 is a ground platform, and a pit 11 is provided on the side of the working platform 3, and a lifting platform 9 is provided in the pit 11 (the lifting platform 9 is a direct application of this application and is not within the protection scope of this application, and it can be a hydraulic lifting platform or a scissors-type lifting platform); a loading plate 10 with a flat plate structure is provided on the top of the lifting platform 9, and the working platform 3 is provided with a T-shaped base frame 1 on the side of the pit 11, a vertical frame 2 with a bracket structure is vertically fixed on the base frame 1, and a pusher hydraulic cylinder 5 is rotatably fitted on the vertical frame 2, and a push plate member 7 with an angle steel structure is fixed on the telescopic end of the pusher hydraulic cylinder 5, and a deflection hydraulic cylinder 6 is rotatably fitted on the lower middle part of the pusher hydraulic cylinder 5, and the deflection hydraulic cylinder 6 is located on the side of the pusher hydraulic cylinder 5 away from the pit 11, and the other end of the deflection hydraulic cylinder 6 is rotatably fitted with the base frame 1.

[0029] In order to improve the pushing strength of the pushing plate 7 and reduce the wear of the pushing plate 7, a block-shaped pushing ridge 71 made of wear-resistant steel is fixed to the bottom of the pushing plate 7. The thickness of the pushing ridge 71 and the single side of the pushing plate 7 connected to it (the single side thickness of the angle steel) is less than the thickness of the wooden base material 14 required for the pushing piece.

[0030] In order to ensure that the push plate 7 can reach the specified position each time and push only one wooden substrate each time, two groups of rod-shaped limit bars 72 are fixed on the push plate 7, and the axis of the limit bars 72 is parallel to the axis of the pusher hydraulic cylinder 5.

[0031] In order to prevent the wear-resistant pusher strips 71 from damaging the wood substrate 14 and to improve the smoothness of the pusher strips 71 sliding on the wood substrate 14, the pusher strips 71 are rotatably coupled with at least two sets of pulleys 73 of roller structure via shafts.

[0032] In order to ensure that the pushing convex strip 71 always exerts a continuous downward pressure on the wooden substrate 14, so that the pushing convex strip 71 can immediately move down to the side of the wooden substrate 14 when it reaches the appropriate position; the telescopic rod of the deflection hydraulic cylinder 6 is provided with an elastic component 8, the main body of the elastic component 8 is a spring 83, and the telescopic rod of the hydraulic cylinder 6 is broken into a concentric first telescopic rod 61 and a second telescopic rod 62, and the first telescopic rod 61 and the second telescopic rod 62 are concentrically connected by the spring 83.

[0033] In order to prevent the spring 83 from being over-pulled and causing its deformation to be irreversible, and to prevent the spring 83 from bending and shifting, the elastic component 8 also includes: a sleeve 81 and a limiting ring 82. The first telescopic rod 61 and the second telescopic rod 62 are each provided with an outwardly convex ring structure on the opposite surface to form a convex ring 63. The two groups of convex rings 63 and the outer periphery of the spring 83 are covered with a cylindrical sleeve 81. The two ends of the sleeve 81 are provided with limiting rings 82 with an inner diameter consistent with the outer diameter of the first telescopic rod 61 and the second telescopic rod 62. The convex ring 63 cannot pass through the two ends of the sleeve 81.

[0034] In order to increase the deflection range of the pusher hydraulic cylinder 5 around the vertical frame 2, the bottom of the deflection hydraulic cylinder 6 is connected to the base frame 1 by an inclined beam 4 with an inclined rod structure. The deflection hydraulic cylinder 6 and the inclined beam 4 rotate in coordination, and the inclined beam 4 is tilted and fixed on the base frame 1 and the vertical frame 2.

[0035] In order to improve the connection strength between the base frame 1 and the vertical frame 2 and enhance the anti-rolling capability of the vertical frame 2 , the vertical frame 2 is fixedly connected to the base frame 1 using reinforcing ribs 12 on both sides.

[0036] In order to reduce the weight of the limiting rod 72 and prevent it from falling seriously due to its weight and affecting the sliding smoothness of the pusher protrusion 71, the limiting rod 72 is a hollow tubular structure, and the end of the limiting rod 72 away from the push plate 7 is hemispherically sealed.

[0037] Brief description of the usage process:

[0038] When in use, the pusher hydraulic cylinder 5, the deflection hydraulic cylinder 6, and the lifting platform 9 are connected to an external hydraulic control system; Figure 1 As shown, the lifting platform 9 is started to make the upper surface of the loading plate 10 flush with the upper surface of the working platform 3, and then the deflection hydraulic cylinder 6 is started to retract. The deflection hydraulic cylinder 6 drives the pushing hydraulic cylinder 5, the pushing plate 7, and the limiting bar 72 to deflect as a whole around the vertical frame 2, reserving an avoidance space for stacking the wooden substrates 14. Then, the wooden substrates 14 to be processed are neatly stacked on the loading plate 10 using a crane or a loader until the uppermost wooden substrate of the wooden substrate 14 is flush with the feeding point 13 of the wooden substrate processing equipment (the feeding point 13 is the feeding point of the wooden substrate processing mechanism in the next step, which is not within the scope of protection of this application. The feeding point 13 is marked here only for the convenience of description and understanding).

[0039] Then the deflection hydraulic cylinder 6 is started to extend, and the extension of the deflection hydraulic cylinder 6 drives the hydraulic cylinder 5, the push plate 7, and the limit bar 72 to deflect as a whole until the limit bar 72 is attached to the upper surface of the uppermost wooden substrate 14, and the push convex strip 71 is located on the side of the wooden substrate 14.

[0040] The hydraulic cylinder 6 is deflected and extended for another distance. Since the deflection of the hydraulic cylinder 5 and the limiting bar 72 is limited by the wooden base material 14, the further extended hydraulic cylinder 6 will compress the spring 83, causing the spring 83 to be in a compressed state (according to the maximum length of the spring 83, the extension distance of the deflection hydraulic cylinder 6 cannot be greater than the maximum compressible length of the spring 83).

[0041] The pushing hydraulic cylinder 5 is started again to extend. After the pushing hydraulic cylinder 5 is extended, the pushing ridge 71 located on the side of the wood base material 14 pushes the uppermost wood base material 14 toward the feeding position 13 under the extension action of the pushing hydraulic cylinder 5, until the uppermost wood base material 14 is pushed to the wood base material processing mechanism behind the feeding position 13, and then the pushing hydraulic cylinder 5 retracts. Under the action of the compressed spring 83, the spring 83 will give a pushing ridge 71 a force to press the wood base material downward, so as the hydraulic cylinder 5 retracts, the pushing ridge 71 will slide on the current uppermost layer of the wood base material 14 under the action of the pulley 73 until the pushing ridge 71 moves to the uppermost edge of the current wood base material 14 and separates from the uppermost layer of the wood base material 14.

[0042] Because the spring 83 exerts a downward force on the pusher rib 7 to hold the wood substrate 14, the moment the pusher rib 71 leaves the uppermost edge of the wood substrate 14, the pusher rib 71 is deflected to the side of the wood substrate 14 by the spring force. At this time, the limit bar 72 limits the downward movement of the pusher rib 71 and presses against the uppermost surface of the wood substrate 14, preventing the pusher rib 71 from moving excessively.

[0043] At this time, because the top layer of wood substrate 14 has been pushed away, the thickness of the existing wood substrate 14 is not flush with the feeding position 13. At this time, the external controller starts the lifting platform 9 again to drive the loading plate 10 to move upward by the thickness of one wood substrate 14. The above action is repeated to complete the feeding process of the next group of wood substrates 14.

[0044] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
