Description

Technical Field

[0001] The utility model relates to the technical field of palletizer auxiliary equipment, in particular to an adjustable clamp for a palletizer. Background Art

[0002] A palletizer is an efficient palletizing equipment with a high degree of automation and good integration. It is mainly used to stack cartons, bags or other packaging materials that have been loaded into containers on pallets and pallets in a certain arrangement for automatic stacking. It can stack multiple layers and then be pushed out for forklifts to transport them to warehouses for storage. Adjustable clamps refer to clamps that can be adjusted according to the size, shape and characteristics of different workpieces to meet diverse production needs. Some of the existing palletizers use adjustable clamps, which clamp materials by driving corresponding clamps with corresponding telescopic cylinders. Some of the palletizers use adjustable clamps, which lift and lower clamps with a single telescopic cylinder. There are some problems with adjustable clamps used in such palletizers. For example, corresponding clamps are driven by corresponding clamps with corresponding telescopic cylinders. As the use time of the telescopic cylinders increases, the working errors between the telescopic cylinders may increase, which in turn affects the synchronization of the operation of the clamps, resulting in instability in the clamping of materials by the clamps. A single telescopic cylinder lifts and lowers the clamp, which may affect the stability of the clamp's force. Utility Model Content

[0024] The working principle of the adjustable clamp for a palletizer provided by the utility model is as follows: during operation, the personnel bolts the threaded hole at the upper end of the connecting plate 4 to the mounting hole of the palletizer stably, thereby stably connecting the adjustable clamp for the palletizer to the palletizer, thereby realizing the stable installation of the adjustable clamp for the palletizer, and the personnel realize the operation of the electric push rod 27 by controlling the switch group 7, and the telescopic end of the electric push rod 27 extends to generate thrust on the two cross bars 35, so that the cross bars 35 push the two longitudinally adjacent connecting rods 34 to rotate in the direction away from the center of the connecting plate 4, and the connecting rods 34 are The lower ends of the connecting rods 32 are driven by the connecting shafts to rotate in the direction away from the center of the connecting plate 4, so that the lower ends of the connecting rods 32 push the working bin 1 to move upward through the vertically adjacent connecting seats 31. At the same time, the guide columns 6 slide inside the corresponding sliding openings to provide a guide for the movement of the working bin 1. The working bin 1 moves downward and drives the clamping plate 5 to move downward through the clamping plate adjustment mechanism 2. When the clamping plate 5 moves downward to the required height, the personnel turns off the electric push rod 37 through the control switch group 7 and realizes the operation of the motor 21. The output shaft of the motor 21 rotates to drive the two-way screw rod 23 to rotate. The driving seats 24 are moved in the driving groove 22 toward the center of the working bin 1, and the driving seats 24 drive the ends of the two vertically adjacent adjusting handles 25 close to the center of the working bin 1 to move toward the center of the working bin 1, so that the ends of the adjusting handles 25 away from the center of the working bin 1 pull the vertically adjacent adjusting seats 24 to move toward the center of the working bin 1, and finally the clamping plate 5 moves toward the center of the working bin 1 to clamp the material. After the clamping is stable, the personnel turn off the motor 21 through the control switch group 7 and realize the electric push rod 27 is running, the telescopic end of the electric push rod 37 is contracted, so that the working bin 1 is moved up, and the external stacker realizes the movement of the adjustable clamp, and then realizes the movement of the material. When the adjustable clamp reaches the required position, the external stacker stops moving the adjustable clamp, and then the electric push rod 27 is operated by controlling the switch group 7. The telescopic end of the electric push rod 27 is extended, so that the clamped material moves down, and the material is stacked. After the material is stacked stably, the personnel realizes the reverse operation of the motor 21 by controlling the switch group 7 to release the material, and then wait for the next material stacking.
