Description

Technical Field

[0001] This utility model relates to the field of wire mesh processing technology, and in particular to a wire mesh welding device. Background Technology

[0002] Ultrasonic welding of nylon mesh is a highly efficient and rapid joining method, particularly suitable for thermoplastic materials like nylon. The principle is that ultrasonic welding utilizes high-frequency vibration waves (typically 20-40kHz) transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces rub against each other, generating heat and causing fusion between molecular layers. This welding method does not require additional welding wire or electrodes; the connection is achieved through the melting of the nylon material itself.

[0003] Existing technology typically uses ultrasonic welding machines to weld wire mesh, and the welding head is used to weld the two ends of the wire mesh together. However, for welding annular wire mesh, it usually requires the support of a mold, which is not conducive to the convenient use of the welding machine. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a wire mesh welding device, which can facilitate the positioning of the wire mesh by sleeve of the wire mesh sheet on the placement shaft and pressing it with the pressing component. By adjusting the alignment of the welding parts of the wire mesh sheet, the device can process several ring-shaped wire mesh products.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A wire mesh welding device is fixedly installed at one end of an ultrasonic welding machine, including a fixed frame, which is fixedly connected to the welding machine. A placement shaft is rotatably connected to the inner wall of the fixed frame. Two drive rollers are symmetrically arranged on both sides above the placement shaft. One end of the central shaft of each drive roller passes through the fixed frame and is connected to a drive assembly, which is fixedly connected to the fixed frame. A gap is provided between the outer side of the placement shaft and the outer side of the drive rollers for placing or driving the wire mesh to move on the outer side of the placement shaft. A pressing assembly is provided between the two drive rollers, and one end of the pressing assembly is hinged to the side wall of the fixed frame.

[0007] Preferably, the pressing assembly includes a first arc plate and a second arc plate, with a gap between the opposite sides of the first arc plate and the second arc plate and adapted to the welding head of the welding machine; a fixed plate and a hinge plate are fixedly connected to both ends of the first arc plate and the second arc plate, respectively; a transmission assembly is provided on the fixed plate and the hinge plate, and a shearing blade is drivenly connected to the transmission assembly; two shearing blades are provided and are slidably connected to the first arc plate and the second arc plate, respectively; a connecting plate is hinged to one end of the hinge plate, and the connecting plate is fixedly connected to the inner wall of the fixed frame.

[0008] Preferably, the bottom surfaces of the first arc plate and the second arc plate are adapted to and fitted against the outer surface of the placement shaft, respectively.

[0009] Preferably, the fixing plate and the hinge plate are respectively provided with mounting grooves; the transmission assembly includes a screw, with sliders screwed to both ends of the screw, the sliders being fixedly connected to the shearing blade, both ends of the screw being rotatably connected to the mounting groove, one end of the screw passing through the mounting groove and being connected to a motor, and the two motors being fixedly connected to the fixing plate and the hinge plate respectively.

[0010] Preferably, the first arc plate and the second arc plate are respectively provided with sliding grooves on their opposite sides, and the inner wall of the sliding groove is slidably connected to the shearing blade.

[0011] Preferably, the cutting edges of the two shearing blades are meshed with each other.

[0013] Compared with the prior art, the present invention has the following advantages and technical effects:

[0014] This invention utilizes a fixed frame to securely mount a welding machine, enabling the ultrasonic welding technology to fix and connect wire mesh placed on the outside of a support shaft. To allow for multi-position welding at the wire mesh joints, two drive rollers are used to drive the wire mesh to slide or roll along the support shaft, adjusting the relative position of the wire mesh and the welding machine to enhance the weld strength. Simultaneously, the pressure assembly is compatible with the welding head, facilitating both pre-positioning of the welding position and trimming of excess wire mesh after welding.

Detailed Implementation

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] It should be noted that all components in the technical solution of this application require necessary additional facilities for water supply, oil supply, power supply, and gas supply for driving and / or control. Unless otherwise stated, they are assumed to be used and equipped with existing technology and no special explanation is required.

[0025] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Depend on Figure 1-5The wire mesh welding device shown is fixedly installed at one end of an ultrasonic welding machine 2. It includes a fixed frame 1, which is fixedly connected to the welding machine 2. A placement shaft 4 is rotatably connected to the inner wall of the fixed frame 1. Two drive rollers 3 are symmetrically arranged on both sides above the placement shaft 4. One end of the central shaft of the drive roller 3 passes through the fixed frame 1 and is connected to a drive assembly. The drive assembly is fixedly connected to the fixed frame 1. A gap is provided between the outer side of the placement shaft 4 and the outer side of the drive roller 3. The gap is used to place or drive the wire mesh to move on the outer side of the placement shaft 4. A pressing assembly is provided between the two drive rollers 3. One end of the pressing assembly is hinged to the side wall of the fixed frame 1.

[0027] Furthermore, ultrasonic welding machines, industrial welding equipment, work by generating a 20kHz (or 15kHz) high-voltage, high-frequency signal. This signal is converted into high-frequency mechanical vibrations by a transducer system and applied to the plastic workpiece. Through friction between the workpiece surface and molecules, the temperature at the interface rises. When the temperature reaches the workpiece's melting point, the interface melts rapidly, filling the gaps. When the vibration stops, the workpiece cools and solidifies under pressure, achieving the welding purpose. Computer-controlled ultrasonic welding enables high-quality welding of plastic products; this is existing technology and will not be elaborated upon further.

[0028] Further optimizing the design, the pressing assembly includes a first arc plate 5 and a second arc plate 6. The first arc plate 5 and the second arc plate 6 have a gap between their opposite sides, which is adapted to the welding head 7 of the welding machine 2. When the welding head 7 descends and comes into contact with the gap, the wire mesh contacts the welding head 7, facilitating welding and allowing the user to clearly see and adjust the position to be welded. A fixed plate 8 and a hinge plate 9 are fixedly connected to both ends of the first arc plate 5 and the second arc plate 6, respectively. The fixed plate 8 and the hinge plate 9 are each equipped with a transmission assembly, which is connected to two shearing blades 10. Two shearing blades 10 are provided and slidably connected to the first arc plate 5 and the second arc plate 6, respectively. Through the relative sliding of the two shearing blades 10, they interlock, cutting the wire mesh positioned between them. A connecting plate 11 is hinged to one end of the hinge plate 9, and the connecting plate 11 is fixedly connected to the inner wall of the fixed frame 1.

[0029] In a further optimized design, the bottom surfaces of the first arc plate 5 and the second arc plate 6 are respectively adapted to and fitted to the outer surface of the placement shaft 4, and the wire mesh is placed between the bottom surfaces of the first arc plate 5 and the second arc plate 6 and the outer surface of the placement shaft 4. The first arc plate 5 and the second arc plate 6 respectively slide in contact with the wire mesh, which facilitates the adjustment of the welding position of the wire mesh.

[0030] Further optimizing the design, mounting slots are provided on both the fixed plate 8 and the hinge plate 9. The transmission assembly includes a screw 12, which is a double-ended screw with opposite rotation directions of the threads at both ends. Rotating the screw 12 allows the sliders 13 screwed to both ends of the screw 12 to move closer or further apart. Slider 13s are screwed to both ends of the screw 12, and the sliders 13 are fixedly connected to the shearing blade 10. Both ends of the screw 12 are rotatably connected to the mounting slots. One end of the screw 12 passes through the mounting slot and is connected to a motor 14. The two motors 14 are fixedly connected to the fixed plate 8 and the hinge plate 9, respectively. The motors 14 can drive the screw 12 to rotate, thereby driving the shearing blade 10 through the sliders 13 to complete the shearing operation on the wire mesh.

[0031] In a further optimized design, the first arc plate 5 and the second arc plate 6 are respectively provided with sliding grooves 15 on their opposite sides, and the inner wall of the sliding grooves 15 is slidably connected to the shearing blade 10.

[0032] In a further optimized design, the cutting edges of the two shearing blades 10 are set to mesh with each other, forming a scissor-shaped structure. The relative movement of the shearing blades 10 achieves the cutting of the wire mesh.

[0033] A further optimized solution includes a drive unit 16, which is fixedly connected to the fixed frame 1 and driven by the central shaft of the drive roller 3. Furthermore, the drive unit 16 is a servo motor, capable of driving the drive roller 3 to rotate with high precision, thereby adjusting the wire mesh. This is existing technology and will not be elaborated further here.

[0034] The working process of this embodiment is as follows:

[0035] After aligning the two ends of the cut wire mesh, it is inserted into the outer side of the placement shaft 4 and fits against the outer side of the drive roller 3. Then, the pressing assembly is flipped down to press the wire mesh tightly onto the placement shaft 4. The welding machine 2 is started, and the welding head 7 will be driven down by the welding machine 2 until it comes into contact with the first arc plate 5 and the second arc plate 6, thus completing the contact with the wire mesh. The contacted wire mesh is then melted and welded using ultrasonic welding technology.

[0036] When there are leftover scraps of wire mesh, the scraps will be placed through the gap between the first arc plate 5 and the second arc plate 6. After the welding head 7 is welded, the motor 14 is started to drive the screw 12 to rotate, which in turn drives the two sliders 13 to move closer to each other, and finally drives the two shearing blades 10 fixedly connected to the sliders 13 to shear and mesh with each other, thereby removing the scraps.

[0037] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
