Detailed description of the invention
Be below a specific embodiment of the present invention, existing the present invention will be further described by reference to the accompanying drawings.
A kind of automatic blackboard eraser descaling machine, mainly comprises mechanical driving device and circuit control system.
As shown in Figure 1, mechanical driving device bag entirety is in box, and frame 1, for supporting whole device, it is enclosed with shell, is provided with dividing plate 14 in shell, and frame 1 is divided into the left and right two parts of being separated by by dividing plate 14; Beating plate 2 comprises a straight-bar and is fixed on the beating head of square plate type of straight-bar front end, pat on head and have equally distributed through hole, is hinged on dividing plate 14, ensures that beating plate 2 two ends can swing up and down in the middle of beating plate 2 through dividing plate 14; Back-moving spring 13 upper end is fixed in frame 1, and back-moving spring 13 lower end is connected to the tail end of beating plate 2; Camshaft 12 is arranged in frame 1, and the cam of camshaft 12 is positioned at the top of beating plate 2 rear end and is close to beating plate 2, and the effect of back-moving spring 13 is exactly the cam making beating plate 2 be close to camshaft 12, and camshaft 12 is connected with DC speed-reducing M210; Below the beating head of beating plate 2, be provided with conveyer belt 7 and belt wheel 8, conveyer belt 7 is fixed with baffle plate, for placing blackboard eraser 9 on baffle plate, the effect of conveyer belt 7 is taken blackboard eraser 9 to beating plate 2 and is patted immediately below head; Conveyer belt 7 side is fixed with block 4, frame 1 is fixed with block 4 with the use of contact 3, belt wheel 8 is connected with DC speed-reducing M16; Be provided with receiver 5 below conveyer belt 7, receiver 5 is in drawer type, and receiver 5 is connected by slide rail with frame 1, can collect and be clapped the chalk powder of falling, when running up to abundant, can concentrate disposable cleaning.
The fixed form of blackboard eraser is that assigned address arranges baffle plate on a moving belt.Simple and convenient during this fixed form placement blackboard eraser, and prevent it from collecting together all around, simultaneously through calculating amplitude of oscillation when beating plate is patted, distance between extreme higher position and extreme lower position is less than the thickness of blackboard eraser, so in the process of patting fast, blackboard eraser also can not drop because of vibrations.
As shown in Figure 2, circuit control system comprises power supply, the master switch SB1 and double-point double-throw switch K111 of series connection; On double-point double-throw switch K111, closing point has connected DC speed-reducing M16 parallel with one another and DC speed-reducing M210, at this moment, be connected with contact switch SQ2 in the circuit of DC speed-reducing M1, in the circuit of DC speed-reducing M2, be connected with the contact switch SQ2 ' linked with contact switch SQ2; Under double-point double-throw switch K1, closing point has connected DC speed-reducing M1, at this moment, be connected with contact switch SQ1 in the circuit of DC speed-reducing M1, the current direction in DC speed-reducing M1 is contrary with its current direction on double-pole double throw switch K1 during closing point.
In this invention, mechanical driving device is divided into two lines, and Article 1 route is that DC speed-reducing M1 drives conveyer belt, and blackboard eraser is put in blackboard eraser fixed dam on a moving belt, blackboard eraser is delivered to assigned address, is sent out after cleaning out by conveyer belt again; Article 2 route is that DC speed-reducing M2 provides power, drives the rotation of camshaft by power and Movement transmit to beating plate, thus drives beating plate to move up and down, and reaches beating plate and pats blackboard eraser object; The function that circuit control system will realize is: after conveyer belt put by blackboard eraser, start DC speed-reducing M1 and blackboard eraser is delivered to assigned address, then DC speed-reducing M2 work drives beating plate to pat blackboard eraser, and clean out after a few second, DC speed-reducing M1 sends out blackboard eraser again.
