Detailed Implementation Modes

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] like Figures 1-3 A double-station end plate feeding device shown in the figure comprises two frame bodies 1, the two frame bodies 1 are arranged side by side on the left and right, a parallel steel rail 2 is arranged in the middle position of the frame body 1, the parallel steel rail 2 is arranged upwardly inclined along the horizontal plane, a pushing device 3 is arranged on the parallel steel rail 2, and a roller 32 that can move on the parallel steel rail 2 with a limited position is arranged on the pushing seat plate 31 of the pushing device 3, so that the pushing seat plate 31 can move along the parallel steel rail 2, and the bottom of the pushing seat plate 31 is arranged on a transmission chain 4 driven by a motor, and the reciprocating motion of the pushing seat plate 31 along the parallel steel rail 2 can be realized through the forward and reverse rotation of the motor, and the pushing seat plate 31 A push plate 33 is provided at the front end, and the push plate 33 pushes the end plate to move and makes the end plate fall into the blanking groove 5 provided at the end of the parallel rail 2. In order to improve the stability of the pushing device 3, notches 11 are provided on both sides of the upper part of the frame body 1, and auxiliary wheels 34 are provided on both sides of the push plate 33 extending outward, and the auxiliary wheels 34 are limitedly moved in the notches 11. In addition, in order to limit the moving distance of the pushing seat plate 31 on the parallel rail 2 and prevent it from derailing, travel switch mounting plates 12 are arranged at intervals on the frame body 1, and a travel switch is arranged on the travel switch mounting plate 12, and a touch plate for touching the travel switch is arranged on the push plate 33.

[0023] The transmission chain 4 includes two parallel sub-chains 41, and the two sub-chains 41 are connected by a transmission shaft 42. In order to adjust the tightness of the transmission chain 4 and improve its stability, a tensioning plate 7 is arranged below the transmission shaft 42. The tensioning plate 7 is moved by an adjusting screw rod 8 connected to it and is fixed by bolts, thereby driving the transmission shaft 42 to move and tension the transmission chain 4.

[0024] The material moving device 6 includes a push rod 61, one end of which is connected to a rotating shaft 62 arranged on a side plate of the blanking trough 5, and the other end is transmission-connected to a material moving cylinder 63. When the end plate falls into the blanking trough 5, the material moving cylinder 63 extends out to drive the push rod 61 to rotate around the axis of the rotating shaft 62, thereby moving the end plate out of the blanking trough 5. A material blocking cylinder 9 is provided at the exit of the left blanking trough 5 to limit the end plate from rolling out. When the end plate needs to be moved out, the material blocking cylinder 9 retracts to release the end plate. In order to make it easier for the end plate to roll down, the two pushing devices 3 and the material moving device 6 are arranged with the left lower and the right higher.

[0025] A double-station end plate feeding device mentioned in the present utility model realizes automatic control by using a PLC controller. During specific use, the end plate is placed on it, and then the motor rotates to drive the transmission chain 4 to move, so that the pushing seat plate 31 moves to drive the push plate 33 to push the end plate, causing the end plate to fall into the blanking chute 5. Subsequently, the material transfer device 6 pushes the end plate away from this device. During the whole process, a time interval can be set. The pushing device 3 on the left moves first. When the end plate on it is transferred, the pushing device 3 on the right just arrives at the blanking chute 5 and continues to push the end plate, while the pushing device 3 on the left retreats to the starting point to replenish the end plate. When the pushing device 3 on the right retreats to the starting point, the pushing device 3 on the left just arrives at the blanking chute 5 again. This cycle repeats, greatly improving the conveying efficiency of the end plate. Of course, the two pushing devices 3 can also be set to move simultaneously and synchronously to be applicable to different occasions.
