Description

Technical Field

[0001] This utility model relates to the field of palletizing machines, specifically a vibration-proof palletizing machine base structure. Background Technology

[0002] In the palletizing process of industrial production, the stability of the palletizer base directly determines the palletizing accuracy, equipment lifespan, and safety of the working environment. Existing palletizer base structures have several shortcomings:

[0003] Firstly, the vibration suppression effect is poor. The palletizer will generate severe vibration during high-speed operation and during the grabbing and placing of goods. This vibration not only leads to a decrease in palletizing positioning accuracy and causes problems such as goods stacking deviation and collapse, but also aggravates the wear of the base and upper actuator components, shortening the service life of the equipment.

[0004] Secondly, there is an imbalance between structural rigidity and flexibility. Most shelters adopt an integrated rigid design to improve stability, which results in insufficient flexibility in the rotation, pitch and other movements of the upper actuator, making them unsuitable for complex palletizing scenarios. Utility Model Content

[0005] The purpose of this invention is to provide a vibration-resistant palletizer base structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vibration-resistant palletizer base structure includes a base platform. A terminal block is installed on the upper side of the base platform.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a technical solution: a vibration-resistant palletizer base structure, including a base 1. A terminal block 19 is bolted to the upper side of the base 1. A bearing base 20 is bolted to the upper center of the base 1. A deep groove ball bearing and a thrust bearing are installed inside the bearing base 20. A vertical shaft 22 is rotatably connected to the shaft center. A ring frame 21 is rotatably connected to the top of the bearing base 20. The ring frame 21 is an aluminum alloy ring frame, which is fixedly connected to the outside of the vertical shaft 22 by a key. A mounting platform 2 is welded to the outer wall of the ring frame 21. The mounting platform 2 is a rectangular steel structure. Two sets of cylinders 6 are arranged on the upper inner part. The two sets of cylinders 6 are fixedly connected to the upper inner part of the mounting platform 2 by a connecting shaft, forming a symmetrical and stable mounting structure. A base plate 3 is bolted to the bottom of the two sets of cylinders 6. The base plate 3 fits against the inner side of the mounting platform 2, improving the installation stability of the cylinders 6.

[0022] The push end of cylinder 6 is equipped with a push plate 17 via a flange. The push plate 17 is a stamped steel plate. The outer wall is bolted with a lower side frame 18. The top of the lower side frame 18 is welded and fixedly connected with a support arm 4. The support arm 4 is an arc-shaped steel structure that can disperse vibration stress. The top of the mounting platform 2 is bolted with an upper frame 16. The upper frame 16 is a rectangular aluminum alloy frame. The upper inner part is equipped with an arc arm 5 via a pin. The arc arm 5 is a high-strength aluminum alloy arc-shaped part. The top is rotatably connected with an arc frame 8 via a pin. The arc radius of the arc frame 8 is the same as that of the arc arm 5 to ensure smooth rotation.

[0023] The top of the support arm 4 is fixedly connected to the bearing seat 14 by bolts. The bearing seat 14 contains a precision bearing. The back is mounted with a motor 15 via a motor mount. The motor 15 is a servo motor with speed precision adjustment function. Its drive end is rotatably connected to the protective sleeve 7 via a coupling. The outer wall of the protective sleeve 7 is fixedly connected to the arc frame 8 by welding. One end of the arc frame 8 is hinged to the arc arm 5 via a pin shaft to achieve precise angle adjustment under motor drive.

[0024] The other end of the arc frame 8 is equipped with a rotating shaft 13 via a bearing. The end of the rotating shaft 13 away from the arc frame 8 is fixedly connected to a hinge rod 12 by welding. The hinge rod 12 is an adjustable telescopic rod used to connect to the upper actuator. One end of the bearing seat 14 is fixedly connected to a forearm 9 by welding. The outer wall of the end of the forearm 9 away from the bearing seat 14 is bolted to a rotating shaft seat 11. A bidirectional bearing is installed inside the rotating shaft seat 11. An assembly frame 10 is bolted to the front end. The assembly frame 10 is a rectangular frame used to install actuators such as palletizing grippers.

[0025] Working principle: Before use, the working air pressure and buffer parameters of cylinder 6 are adjusted through the air circuit control system according to the weight, specifications and stacking speed of the goods to be stacked, and the speed and angle adjustment accuracy of motor 15 are set through the servo motor controller.

[0026] During operation, the terminal block 19 connects to the power supply of the equipment, the upper actuator of the palletizer is installed and fixed through the assembly frame 10, and the pipelines are neatly arranged through the through-hole structure of the forearm 9.

[0027] When the grasping and stacking actions generate vibration, the support arm 4 transmits the vibration to the lower frame 18 and the push plate 17. The two sets of symmetrical cylinders 6 extend and retract in real time according to the direction and intensity of the vibration, and apply reverse force through the push plate 17 to cancel the vibration. At the same time, the hinge structure of the arc arm 5 and the arc frame 8 and the flexible connection of the hinge rod 12 further buffer the residual vibration and prevent the vibration from being transmitted to the mounting platform 2 and the base 1.

[0028] When it is necessary to adjust the stacking direction, the vertical shaft 22 (not shown in the diagram) is driven to rotate around the bearing base 20 by the drive mechanism, and the ring frame 21 drives the mounting platform 2 to rotate synchronously. When it is necessary to adjust the pitch angle of the actuator, the motor 15 drives the protective cylinder 7 to rotate, which drives the arc frame 8 to rotate around the hinge point of the arc arm 5, so as to achieve precise angle adjustment.

[0029] The forearm 9 drives the assembly frame 10 to rotate through the pivot seat 11, and in conjunction with the extension and retraction of the hinge rod 12, it realizes multi-dimensional action of the actuator to meet the needs of complex palletizing scenarios.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
