Description

Technical Field

[0001] The utility model relates to the field of medical dressing equipment, and particularly relates to a long-distance ultrasonic sealing device. Background Art

[0002] In traditional ultrasonic sealing devices, the speed of the anvil wheel is usually fixed and directly determined by gear transmission, and it cannot be adjusted according to the properties and thickness of the processed materials. This may cause excessive stretching of the materials during the sealing process, resulting in holes or false soldering, seriously affecting the sealing quality. In addition, the prior art also has the following deficiencies:

[0003] The welding head is prone to wear after long-term use, resulting in false soldering. After wear, it needs to be rotated manually by a certain angle, which is inconvenient to use. The distance between the anvil wheel and the welding head is large, which is prone to false soldering. During operation, due to the relatively high speed, the anvil wheel will have slight fluctuations, resulting in imbalance on both sides. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a long-distance ultrasonic sealing device, which introduces an adjustable-speed anvil wheel driving device, a down pressing cylinder with constant pressure, the integration of a fine-tuning plate and a transducer, a welding head design with automatic rotation and uniform wear, and a synchronous sliding system, solves the problem of unstable sealing effect existing in the existing ultrasonic sealing device, and greatly improves the sealing quality, production efficiency and service life of the equipment.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A long-distance ultrasonic sealing device includes an ultrasonic welding head, the ultrasonic welding head is arranged opposite to the anvil wheel, and the anvil wheel is driven to rotate by an anvil wheel driving device; the anvil wheel is installed on a lifting frame by the anvil wheel driving device, and the lifting frame is driven to move up and down by a down pressing cylinder.

[0007] Preferably, the ultrasonic welding head is installed on a fine-tuning plate, a transducer is installed at the bottom of the fine-tuning plate, and the transducer is electrically connected to the ultrasonic welding head.

[0008] Preferably, both the fine-tuning plate and the lifting frame are connected to a lateral support, the lateral support is connected to the right side wallboard through a horizontal sliding rail, and the lateral support is driven to move by a transverse moving motor.

[0009] Preferably, the ultrasonic welding head is installed on the fine-tuning plate through a bearing, and the ultrasonic welding head is driven to rotate by a rotating motor through a belt pulley and a belt.

[0010] Preferably, a left side wallboard is provided on the opposite side of the right side wallboard, and the left side wallboard is connected to the lateral support through a horizontal sliding rail.

[0012] The utility model can achieve the following beneficial effects:

[0013] 1. A driving device for the anvil wheel is introduced, usually a motor, which enables the rotation speed of the anvil wheel to be adjusted according to the transverse movement speed, effectively avoiding excessive pulling of the raw material during the sealing process and ensuring the sealing quality.

[0014] 2. The ultrasonic welding head is driven by a pressing cylinder to keep in constant pressure contact with the anvil wheel, ensuring that the best contact state is always maintained between the welding head and the anvil wheel during the sealing process and avoiding false soldering.

The set screw and the socket head cap bolt with a glass bead on the fine-tuning plate cooperate to accurately adjust the parallelism between the welding head and the anvil wheel, ensuring the stability and consistency during the sealing process.

[0016] 4. The ultrasonic welding head is driven by a rotating motor to rotate a certain angle when it is in the non-working position, making the wear of the welding head more uniform during use, extending the service life of the welding head, and also eliminating the trouble of manual adjustment.

[0017] 5. The whole device is driven by a transverse movement motor to realize the synchronous sliding of the ultrasonic welding head and the anvil wheel, ensuring the relative position stability of the two during the sealing process and improving the sealing efficiency and accuracy.
