In the specific embodiment, as shown in fig. 1 and fig. 2, the upper end of the bin 2 is connected with a feeding and conveying mechanism, the feeding and conveying mechanism is a belt transmission mechanism which is obliquely arranged, a finished welding rod near the ground is conveyed upwards to the upper part of the bin 2 by the feeding and conveying mechanism, a zigzag feeding channel 8 is arranged in the bin 2, an included angle between the inclined surface of the zigzag feeding channel 8 and the horizontal plane is 10-30 degrees, preferably 15 degrees, a blanking port 201 and a supplementing port 202 are sequentially arranged along the inclined surface of the bottom of the zigzag feeding channel 8 from top to bottom, the welding rod rolls along the zigzag direction after entering the zigzag feeding channel 8 and finally reaches the bottom of the bin 2, the rolling process is a dynamic arrangement process of the welding rod, and in the prior art, the direct blanking to the bottom of the bin 2 is easy to cause the state that the welding rod is mutually intersected and the direction is uncertain;
a loosening mechanism is arranged between the blanking port 201 and the blanking channel 203 and between the supplementing port 202 and the supplementing channel 204, the loosening mechanism comprises two rollers 7 rotating in the same direction, a gap between the two rollers 7 and the corresponding blanking channel 203 or supplementing channel 204 are positioned on the same plane, the rotating shafts of the two rollers 7 are erected in the supporting frame 1 through bearings, a parallelogram synchronous mechanism is connected between the two rotating shafts, as shown in fig. 1, a hinged connecting rod is arranged between the synchronous mechanism and the rotating shaft of the grinding wheel below the synchronous mechanism, when the corresponding grinding wheel rotates, the synchronous mechanism is driven to reciprocate, so that the two rollers 7 are driven to synchronously reciprocate in the same direction, the originally stable mutually-crossed and mutually-compacted welding rod states in the bin are damaged, so that the welding rods can loosen and flow into the blanking channel 203 and the supplementing channel 204, and the condition of difficult blanking caused by mutual extrusion and cross between welding rods existing during blanking intervals is avoided;
based on the structure, a closed transmission mechanism in the support frame 1 rotates and drives the receiving grooves 3 to move, each receiving groove 3 sequentially moves to the lower parts of the first grinding wheel 401 and the second grinding wheel 402, a counter 5 is arranged below each of the first grinding wheel 401 and the second grinding wheel 402, a telescopic stop device is arranged at the rear of each of the first grinding wheel 401 and the second grinding wheel, the telescopic stop device is selected as an air cylinder, the telescopic end of the air cylinder extends to the lower end position of the blanking channel 203 in an upward inclined mode, when the corresponding grinding wheel does not work, the extending state is formed, welding rods are blocked at the uppermost end of the grinding wheel, the condition that the welding rods fall off freely is avoided, when the grinding wheel acts, the air cylinder is in a contracted state, the welding rods can be driven by the grinding wheel and fall along the circumferential direction of the grinding wheel, and in the falling process, the counting of the welding rod falling quantity is performed through the counter 5;
the closed transmission mechanism drives the material receiving groove 3 to sequentially pass through the lower parts of the first grinding wheel 401 and the second grinding wheel 402, firstly, when the material receiving groove 3 is positioned under the first grinding wheel 401, the falling speed, the extending material blocking action of the telescopic material blocking device and the stopping action of the first grinding wheel 401 cannot be unified absolutely, and no delay exists, so that errors in quantity can be generated when the first grinding wheel 401 drives the falling welding rods, when the quantity of the first grinding wheel 401 is designed to drive the falling welding rods, the working is stopped when the quantity of the first grinding wheel 401 reaches 70% -80% of the preset quantity, the final actual quantity can be larger than the preset quantity, the step is a coarse packet, the step ensures that the quantity of the falling welding rods does not exceed the preset quantity, then the closed transmission mechanism continues to rotate, the material receiving groove 3 stops when the welding rods move forwards under the second grinding wheel 402, the telescopic device 601 in the lifting weighing mechanism stretches upwards, the bearing plates 603 at the two sides of the upper end of the weighing device 602 lift the welding rods in the receiving groove 3, the weighing device 602 weighs, then the second grinding wheel 402 drives the welding rods to fall so as to supplement the rest weight, as the supplement quantity is less than 20% -30% of the total weight, the grinding speed of the second grinding wheel 402 also reduces, so that the transmission continuity can be ensured, the problem of larger weighing error caused by too fast falling speed of the welding rods can be ensured, when the welding rods fall to supplement the weight of less than 1 welding rod, the operation is carried out in two cases, when the weight of less than half the weight is less than 1 welding rod, the driving of the welding rods to fall is stopped, when the weight of more than half the weight is greater than 1 welding rod is driven, after the supplement is finished, the telescopic device 601 contracts to the original position, this ensures that the error between the final actual number of falling electrodes and the required target number is less than half a root.
The support frame 1 is provided with the horizontal direction in second grinding wheel 402 below both sides position and expects board 9, it is greater than the horizontal width of draw-in groove to expect board 9 interval, the setting height of expecting board 9 is less than the open position of receiving groove 3 upper end, the slope that expects the in-process of welding rod unloading appears drops the phenomenon has been avoided in the setting of board 9 of expecting, in the in-service use, it is in the form that can follow vertical lift to expect board 9 to set up, when the draw-in groove in the lifting weighing machine constructs rises, it is the horizontality to expect board 9 to rise along with this and push the welding rod of slope, realize the arrangement function of welding rod group, and the condition that the influence weighing accuracy that the slope welding rod was led to the supporting to the board 9 of expecting that appears in the lifting weighing process can be avoided.
A blanking guide mechanism is arranged on one rotation output side of the second grinding wheel 402, and comprises two vertical baffle plates with a distance not larger than the width of the receiving groove 3; the striker plate includes the transverse support board 10 of upper end and fixes at its lower extreme and along a set of flexible board 11 of transversely arranging, flexible board 11 material is transparent plastics or transparent rubber, the transverse support board 10 bottom that is close to second grinding wheel 402 leans forward, inclined plane and vertical face contained angle are 10-50 degrees, preferably 30 degrees, blanking guiding mechanism can provide the auxiliary guidance in-process that drops for the welding rod of second grinding wheel 402 grinding output, and because the transverse support board 10 bottom that is close to second grinding wheel 402 leans forward, the bottom of the flexible board of its lower extreme also has the trend of forward slope, the interval between the flexible board of two transverse support boards 10 lower extreme is more close to down, the welding rod drops down along the interval between two sets of flexible boards 11, the welding rod is through the buffering of flexible board and the restriction of dropping the position, supplementary welding rod falls the form of the upper end of subcontracting, the process and the cost of setting up additional arrangement mechanism of post-stage manual work has been avoided.
The power source of the whole bagging machine can be a group of motors, but in order to save energy, a driving motor is set by the closed transmission mechanism, then the first grinding wheel 401 and the second grinding wheel 402 are respectively provided with respective driving motors, and the first grinding wheel 401 and the second grinding wheel 402 respectively drive two rollers 7 in the loosening mechanism above each through a connecting rod and a parallelogram synchronous mechanism.
