Description

Technical Field

[0001] The present invention relates to the technical field of wood-based panels, and particularly to a double-infeed board conveyor. Background Art

[0002] Existing wood-based panel production lines generally adopt a single-infeed mechanism. After the lifting table feeds each stack of boards to subsequent equipment, the lifting table needs to be lowered to a low position before feeding the boards again. During this pallet-changing period, it takes a long time, and all subsequent wood-based panel processing equipment has been running idly, resulting in a waste of electric power resources.

[0003] For this reason, the Chinese Utility Model Patent Authorization Publication No. CN205222096U discloses a wood-based panel double-infeed device, which includes a first infeed unit and a second infeed unit connected in series. Both the first infeed unit and the second infeed unit include a lifting table and a pusher mechanism above the lifting table. The pusher mechanism includes a guide rail horizontally arranged above the lifting table, a slider on the guide rail, a pusher fixed on the slider, and a first cylinder fixed on the guide rail for driving the slider.

[0004] However, the above-mentioned wood-based panel double-infeed device is actually two infeed units connected in series (which actually pushes the slab to the next working station, and the applicant believes it is outfeed), and can only send the board to the next working station unidirectionally; there is no baffle device to jointly align the slab with the universal ball platform. In addition, this patent cannot automatically achieve left-right horizontal infeed and longitudinal outfeed.

[0005] The Chinese Utility Model Patent Authorization Publication No. CN213678714U discloses a multifunctional wood-based panel double-infeed device, which includes a first infeed unit, a second infeed unit, a board conveyor, board conveyor rollers, a slab conveying and guiding roller structure, a slab output angle adjustable structure, and an adjustable slab surface cleaning wheel structure. Both the first infeed unit and the second infeed unit include a first infeed support, a second infeed support, a pusher, a limit switch, a lifting motor, a rotating screw, a lifting nut, and a slab loading table. A pusher is horizontally bolted to the upper part inside the first infeed support. The arrangement of the conveyor rollers, long axle, guiding frame, connecting seat, and connecting frame in this patent is beneficial to conveying the slab and ensuring the tightness efficiency of the board. It is actually two infeed units connected in series (which actually pushes the slab to the next working station, and the applicant believes it is outfeed), and can only send the board to the next working station unidirectionally; there is no baffle device to jointly align the slab with the universal ball platform. In addition, this patent cannot automatically achieve left-right horizontal infeed and longitudinal outfeed.

[0006] The Chinese invention patent application publication number CN111347502A discloses a blanking feeding and moving device in the production of composite floors, including a support frame, a moving mechanism, a clamping mechanism, and a conveying mechanism; the moving mechanism is installed on the support frame to reciprocate on the support frame; the clamping mechanism is installed on the moving mechanism to clamp the composite board and drive the composite board to move along with the moving mechanism; the conveying mechanism is installed on the support frame, and the moving mechanism pushes the composite floor to slide on the conveying mechanism so that the composite floor enters the next process equipment. The blanking feeding and moving device of the present invention can cooperate with the composite floor drying device in the previous process of the composite floor, eliminating the need for manual conveying, saving a large amount of human resources. At the same time, the composite floor conveyed by the universal ball platform conveying mechanism is automatically tangent to the guide wheels on both sides in the blanking device, thus achieving automatic correction. The design is ingenious and reasonable, and the work is safe and reliable. However, this patent does not provide a feeding drive mechanism, resulting in a long feeding time. In addition, this patent does not have a feeding guiding function, and it cannot automatically achieve left-right horizontal feeding and longitudinal discharging. Summary of the Invention

[0038] In order to smoothly send the slab fed by the left feeding driving mechanism 200 and at least one left pressing wheel mechanism, and the right feeding driving mechanism 300 and at least one left pressing wheel mechanism to the discharging side of the rack, a universal wheel platform is arranged between the upper rack 102 and the lower bracket 101, and a pushing plate mechanism is arranged on the other side of the rack opposite to the discharging side.

[0039] The universal wheel platform is used to receive the slab fed from the left side of the rack by the cooperation of the left feeding driving mechanism 200 and the left pressing wheel mechanism and the slab fed from the right side of the rack by the cooperation of the right feeding driving mechanism 300 and the right pressing wheel mechanism. The pushing plate mechanism pushes the slab on the universal wheel platform to the discharging side of the rack and is sent out by the discharging driving mechanism 600 and the discharging pressing wheel mechanism.

[0040] The height positions of the left feeding driving mechanism 200, the left pressing wheel mechanism, the right feeding driving mechanism 300, the right pressing wheel mechanism, the discharging driving mechanism 600, and the discharging pressing wheel mechanism are adapted to the height position of the plate conveying surface of the universal wheel platform.

[0041] The universal wheel platform includes a plurality of longitudinal beams 401 spacedly installed on the rack, a plurality of cross bars 402 spacedly installed on the longitudinal beams 401, a plurality of universal wheels 403 installed on the cross bars 402, and a cover plate 404. The cover plate 404 is fixed on the longitudinal beams 401 and the cross bars 402. Universal wheel through holes are opened at positions of the cover plate 404 corresponding to each universal wheel 403, and part of the universal wheels 403 penetrate through the universal wheel through holes. The structure of the universal wheel platform is simplified, and the slab can be placed in place without additional mechanical actions, which is convenient for discharging the plate.

[0042] The pusher mechanism includes a pusher driving mechanism 501, a pusher head 504 driven by the pusher driving mechanism 501 to perform linear reciprocating motion, and two sets of slide rail mechanisms 502 and 503. The pusher driving mechanism 501 drives the pusher head 504 to push the slab of the caster platform to the plate-out side of the rack and is sent out by the plate-out driving mechanism 600 and the plate-out pressing wheel mechanism.

[0043] The pusher head 504 is connected to the slide rail mechanisms 502 and 503 to ensure the smoothness of the pusher head 504 during linear reciprocating motion. The slide rail mechanisms 502 and 503 are arranged on the left and right sides of the pusher driving mechanism 501.

[0044] In addition, in order to straighten the slabs fed from the left side of the rack by the cooperation of the left-side plate-in driving mechanism 200 and the left-side pressing wheel mechanism and the slabs fed from the right side of the rack by the cooperation of the right-side plate-in driving mechanism 300 and the right-side pressing wheel mechanism, and facilitate plate-out, the present invention is provided with a left-side baffle mechanism on the left side of the rack. The left-side baffle mechanism cooperates with the caster platform to guide the slabs entering from the left side of the rack; a right-side baffle mechanism is provided on the right side of the rack. The right-side baffle mechanism cooperates with the caster platform to guide the slabs entering from the right side of the rack.

[0045] The left-side baffle mechanism and the right-side baffle mechanism of the present invention have the same structure, and both include a baffle seat 802 installed on the rack and a baffle 801 installed on the baffle seat 802. The free end of the baffle 801 is bent downward to facilitate the slabs to enter the baffle 801.

[0046] The working principle of the present invention is as follows:

[0047] The slabs on the left and right sides enter the caster platform on the caster platform alternately from the left and right sides of the rack through the left-side plate-in driving mechanism 200 and the left-side pressing wheel mechanism and the right-side plate-in driving mechanism 300 and the right-side pressing wheel mechanism. During the process of the slabs entering the casters 403 on the caster platform, the left-side baffle mechanism and the right-side baffle mechanism conduct lateral plate-in guiding on the slabs. The slabs resting on the casters 403 of the caster platform are longitudinally guided by the combined action of the left-side baffle mechanism, the right-side baffle mechanism, and the casters 403 of the caster platform, and then move to the plate-out side of the rack under the push of the pusher mechanism, and are sent to the next process section through the cooperation of the plate-out driving mechanism 600 and the plate-out pressing wheel mechanism.
