Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to an ultrasonic welding machine with a protective mechanism. Background Technology

[0002] Ultrasonic welding machines are highly efficient industrial welding equipment. Their working principle involves using a generator to produce high-frequency signals, which are then converted into high-frequency mechanical vibrations by a transducer system. These vibrations act on plastic workpieces. The frictional heat generated by these vibrations rapidly melts the workpiece interface, which then cools and solidifies under pressure, thus achieving welding. Ultrasonic welding machines offer advantages such as short welding time, high weld strength, and no need for adhesives, making them widely used in various fields including automotive manufacturing, plastics and electronics production, toy and stationery manufacturing, and medical supplies manufacturing. Furthermore, they are easy to operate, energy-efficient, and environmentally friendly, making them an indispensable piece of equipment in modern industrial production.

[0003] During welding operations, the use of ultrasonic welding machines may generate a certain amount of harmful gases. These gases include, but are not limited to, various volatile organic compounds, ozone, and other substances that may be harmful to the environment and human health. If these harmful gases are not properly handled in the work environment and instead diffuse into the work area, workers may inadvertently inhale them during routine operations. Inhalation of these harmful gases may irritate the worker's respiratory system, and long-term exposure may lead to more serious health problems, such as respiratory diseases, neurological damage, and other potential health risks. Therefore, an ultrasonic welding machine with protective mechanisms is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic welding machine with a protective mechanism to solve the problem that welding may generate harmful gases in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic welding machine with a protective mechanism, comprising a welding machine base, a positioning support fixedly installed on the welding machine base, a welding machine body slidably installed on the positioning support, an ultrasonic welding head provided on the welding machine body, a protective mechanism installed on the positioning support, the protective mechanism comprising a drive cylinder fixedly installed inside the positioning support, a sliding bracket fixedly installed at the output end of the drive cylinder, a movable sliding sleeve fixedly installed on the sliding bracket, a hollow support arm fixedly installed on the movable sliding sleeve, a protective cover fixedly installed at the end of the hollow support arm, and a processing mechanism connected to the hollow support arm.

[0006] Preferably, the protective cover has an inlet and outlet through hole, and the hollow support arm is fixedly installed with a positioning sleeve at its end.

[0007] Preferably, the positioning support column has a movable notch, and the sliding bracket is movably installed on the positioning support column through the movable notch.

[0008] Preferably, the hollow support arm is slidably mounted on the positioning support via a movable sliding sleeve, the protective cover is fixedly mounted on the end of the hollow support arm via a positioning sleeve, the ultrasonic welding head extends into the protective cover through an inlet / outlet through-hole, a connection interface is provided in the middle of the sliding bracket, and the output end of the drive cylinder is connected to the sliding bracket via the connection interface.

[0009] Preferably, the processing mechanism includes a connecting pipe connected to the hollow support arm, a volute fixedly installed at the end of the connecting pipe, a conveying pipe fixedly installed on one side of the volute, a drive motor fixedly installed on the other side of the volute, an activated carbon canister fixedly installed at the end of the conveying pipe, a drive shaft fixedly installed at the output end of the drive motor, and a fan blade fixedly installed on the drive shaft.

[0010] Preferably, the volute is provided with a bearing, and the drive shaft is rotatably mounted on the volute via the bearing.

[0011] Preferably, the output end of the drive motor is provided with a coupling, the drive shaft is fixedly installed on the output end of the drive motor through the coupling, the fan blade is rotatably installed in the volute through the drive shaft, one end of the conveying pipe is connected to the volute, and the other end of the conveying pipe is connected to the activated carbon canister.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, after the drive cylinder extends, it causes the sliding bracket to displace downwards. Subsequently, the downward displacement of the sliding bracket drives the hollow support arm on the movable sleeve to move downwards accordingly. The downward movement of the hollow support arm then causes the protective cover to move downwards, thereby covering the two workpieces. This covering action aims to prevent harmful gases generated during welding from diffusing into the work area, thus ensuring the safety of personnel in the work area.

[0014] 2. In this application, after the drive motor is started, the drive motor will drive the drive shaft to rotate at high speed, which in turn will drive the fan blades to rotate at high speed inside the volute. This process creates a negative pressure inside the volute, causing harmful gases inside the protective cover to be drawn into the volute. Subsequently, these harmful gases are transported to the activated carbon canister through a delivery pipe for purification treatment. Attached Figure Description

[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] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an ultrasonic welding machine with a protective mechanism, including a welding machine base 3, a positioning support 4 fixedly installed on the welding machine base 3, a welding machine body 1 slidably installed on the positioning support 4, an ultrasonic welding head 2 provided on the welding machine body 1, a protective mechanism 5 installed on the positioning support 4, and a processing mechanism 6 connected to the hollow support arm 504. Through the combined use of the protective mechanism 5 and the processing mechanism 6, the harmful gases generated during welding can be treated, reducing the risk to workers.

[0022] like Figure 2 and Figure 3 As shown, the protective mechanism 5 includes a drive cylinder 506 fixedly installed inside the positioning support column 4. A sliding bracket 507 is fixedly installed at the output end of the drive cylinder 506. A movable sliding sleeve 505 is fixedly installed on the sliding bracket 507. A hollow support arm 504 is fixedly installed on the movable sliding sleeve 505. A protective cover 501 is fixedly installed at the end of the hollow support arm 504. An inlet / outlet through hole 503 is opened on the protective cover 501. A positioning sleeve 502 is fixedly installed at the end of the hollow support arm 504. A movable notch is opened on the positioning support column 4. The sliding bracket 507 is movably installed on the positioning support column 4 through the movable notch.

[0023] Specifically, when the drive cylinder 506 extends, it triggers a series of mechanical actions. First, the sliding bracket 507 moves downward as the cylinder extends. As the sliding bracket 507 descends, it further causes the hollow support arm 504 on the movable sleeve 505 to move downward as well. The descent of the hollow support arm 504 causes the protective cover 501 to move downward as well, ultimately covering the two workpieces. This design ensures that harmful gases generated during welding do not diffuse into the work area, thus protecting personnel in the work area from the effects of these harmful gases.

[0024] like Figure 2 and Figure 4 As shown, the processing mechanism 6 includes a connecting pipe 603 connected to the hollow support arm 504. A volute 604 is fixedly installed at the end of the connecting pipe 603. A conveying pipe 602 is fixedly installed on one side of the volute 604. A drive motor 607 is fixedly installed on the other side of the volute 604. An activated carbon canister 601 is fixedly installed at the end of the conveying pipe 602. A drive shaft 606 is fixedly installed at the output end of the drive motor 607. A fan blade 605 is fixedly installed on the drive shaft 606. A bearing is provided on the volute 604. The drive shaft 606 is rotatably mounted on the volute 604 through the bearing.

[0025] Specifically, when the drive motor 607 is started, it begins to rotate the drive shaft 606 at high speed. As the drive shaft 606 rotates at high speed, the fan blades 605 also rotate at extremely high speeds within the volute 604. This high-speed rotation creates a negative pressure zone inside the volute 604, which effectively draws harmful gases from the protective cover 501 into the volute 604. Once the harmful gases are drawn into the volute 604, they are transported to the activated carbon canister 601 through the delivery pipe 602. Inside the activated carbon canister 601, these harmful gases undergo a purification process, thereby removing or reducing their harmful components.

[0026] Working principle: During use, two workpieces can be placed on the welding machine base 3. After placement, the ultrasonic welding head 2 on the welding machine body 1 can be controlled to descend, thus welding the two workpieces together. Before welding, the drive cylinder 506 can be extended. The extension of the drive cylinder 506 will cause the sliding bracket 507 to move downwards. This downward movement of the sliding bracket 507 will then cause the hollow support arm 504 on the movable sliding sleeve 505 to move downwards. Finally, the downward movement of the hollow support arm 504 will cause the protective cover 501 to move downwards, thus covering the two workpieces. The protective cover 501 is designed to prevent harmful gases generated during welding from spreading to the work area, thus protecting personnel in the work area. Simultaneously, the drive motor 607 can be activated, which in turn drives the drive shaft 606 to rotate at high speed. This high-speed rotation of the drive shaft 606 drives the fan blade 605 to rotate at high speed within the volute 604, creating a negative pressure that draws harmful gases from the protective cover 501 into the volute 604. The harmful gases drawn into the volute 604 are then transported through the delivery pipe 602 to the activated carbon canister 601 for purification.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
