Description

Technical Field

[0001] This utility model relates to the field of processing machinery technology, specifically a lifting mechanism. Background Technology

[0002] Ultrasonic welding converts a 50 / 60 Hz current into 15, 20, 30, or 40 kHz electrical energy using an ultrasonic generator. This high-frequency electrical energy is then converted into mechanical motion of the same frequency by a transducer. This mechanical motion is then transmitted to the welding head via an amplitude converter. The welding head transfers the received vibrational energy to the joint of the workpieces to be welded, where the vibrational energy is converted into heat energy through friction, melting the plastic. Ultrasonic welding can be used not only to weld hard thermoplastics but also to process fabrics and films.

[0003] Existing ultrasonic lifting mechanisms are generally used to adapt to different application environments. However, most existing lifting mechanisms that work with ultrasonic equipment use telescopic motors or cylinders as power sources for lifting. When multi-site welding operations are used, a power source needs to be added, and it is difficult to achieve synchronous lifting, which affects subsequent operations. Therefore, there is an urgent need to provide a lifting mechanism. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a lifting mechanism in which a servo motor operates, and through the cooperation of the active pulley, driven pulley and transmission belt, drives two sets of geared motors to work synchronously. The connecting rod follows the rotation of the geared motor, which in turn drives the eccentric seats and eccentric rods at both ends of the connecting rod to perform eccentric movements, which apply power to the movable plate, causing the movable plate to move up and down along the bottom of the connecting frame, thereby driving the ultrasonic components connected to the connecting frame to move up and down synchronously, realizing simultaneous lifting of multiple positions. Furthermore, the use of dual geared motors to transmit power can ensure heavy loads.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A lifting mechanism comprising:

[0008] As a connecting base frame, the connecting top plate is connected to the bottom of the connecting top plate, and the bottom of the connecting frame is connected to connecting plate one and connecting plate two, and a movable plate is slidably connected on the connecting frame;

[0009] The power unit, connected to the connecting frame, provides power to drive the lifting components.

[0010] The lifting assembly is provided in multiple sets, and each set of lifting assemblies is connected to the connecting frame and moves synchronously with the power assembly.

[0011] As a preferred embodiment of the lifting mechanism described in this utility model, the connecting plate one and the connecting plate two are each provided in two sets. The two sets of connecting plates one are symmetrically connected at the center of the bottom of the connecting frame, and the two sets of connecting plates two are provided at the two ends of the bottom of the connecting frame.

[0012] In a preferred embodiment of the lifting mechanism described in this utility model, multiple sets of hinge seats are connected to the movable plate, and the hinge seats are arranged in a one-to-one correspondence with the eccentric rods.

[0013] As a preferred embodiment of the lifting mechanism described in this utility model, the power component includes a servo motor connected to the left connecting plate and two sets of reduction motors. The left reduction motor is disposed on the outer side of the left connecting plate, and the right reduction motor is mounted on the right connecting plate. The input end of the servo motor is connected to the driving pulley, and the input ends of both sets of reduction motors are connected to the driven pulleys.

[0014] In a preferred embodiment of the lifting mechanism described in this utility model, the left-side reduction motor and servo motor are arranged vertically parallel to each other, the right-side reduction motor and the left-side reduction motor are arranged symmetrically, and the driving pulley is connected to the two sets of driven pulleys by a transmission belt.

[0015] As a preferred embodiment of the lifting mechanism described in this utility model, the lifting assembly includes a connecting rod connected to the output ports of two sets of reduction motors. The connecting rod passes through both sides of the reduction motors, and both ends of the connecting rod are connected to eccentric seats. An eccentric rod is hinged to the outside of the eccentric seat, and the other end of the eccentric rod is hinged to the hinge seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The servo motor operates by cooperating with the active pulley, driven pulley, and transmission belt to drive two sets of geared motors to work synchronously. The connecting rod follows the rotation of the geared motor, which in turn drives the eccentric seats and eccentric rods at both ends of the connecting rod to perform eccentric movements. This applies power to the movable plate, causing the movable plate to move up and down along the bottom of the connecting frame. This, in turn, drives the ultrasonic components connected to the connecting frame to move up and down synchronously, enabling simultaneous lifting and lowering of multiple positions. Furthermore, the use of dual geared motors to transmit power ensures heavy-duty operation. Attached Figure Description
