21062G64K2219 - Automatic Welding Machine for Longitudinal Seam Joints of 14m Container Corrugated Board

Base and pad

The machine base is the basic support of the machine, which is composed of base, support, lifting mechanism and other parts. The machine base is made of steel structure and has enough rigidity to withstand the clamping force. There is a protective gas inlet port on the back of the liner, and the liner and the liner seat can be electrically lifted. There are multiple sets of wedge-shaped blocks under the cushion seat, the wedge-shaped blocks are installed on the fixed bottom plate, and the motor drives the bottom plate to make corresponding movements through the reducer, so that the lifting action of the cushion can be realized. The working height of the pad can be controlled by the proximity switch, so as to realize the function of repeated lifting and lowering, and at the same time, the highest and lowest limit switches are installed on the base. The lining strip adopts a water-cooled structure, which is cooled by circulating water in the cooling water tank.

piano key holder

The key clamp has a left-right symmetrical structure and is installed on the machine base, which can apply pressure to both sides of the welding seam respectively. The specific clamping method of the keyboard clamp is to inject compressed air into the air bag, and the air bag expands to apply pressure to the lever mechanism. It can be adjusted as needed (usually 7~25kgf/cm) to meet the welding requirements of different thicknesses and lengths. The clamping body controls the clamping or loosening of the left and right pressing fingers respectively through the foot switch.

Adjustment of the width between the pressing fingers: The width between the pressing fingers needs to be determined according to the welding process and the thickness of the plate. The width between the pressing fingers can be changed by adjusting the rear end support adjusting screw of the pressing plate to meet the different welding processes and plate thickness. requirements.

Beam and welding trolley

The beam is fixed on the clamping body through the linear guide rail, and the DC motor drives the gear to mesh with the rack through the micro reducer to realize the movement. Due to the use of linear guides, the trolley runs smoothly and flexibly. The speed of the DC motor can be adjusted steplessly, and the traveling speed of the trolley is set at 65-1250mm/min. When the trolley needs to be moved quickly, the trolley locking handle can be pulled to disengage the gear from the rack, and the trolley can be pushed to move quickly. The travel of the trolley can be set as required to realize digital control, and a limit is set at the end of the beam to ensure the safety of personnel and equipment.

Air system

The compressed air system is built-in, which consists of air source triples, solenoid valves, joints and other parts. In general use, the pressure of the pressure reducing valve can be adjusted to 0.2 ~ 0.6Mpa. When welding thinner plates, a lower air pressure should be used, and the gas pressure should be correspondingly increased when the plate thickness increases or the deformation increases.

Weld alignment device

The device adopts the method of pneumatic centering and is installed on one side of the gasket seat, and the number of installed centering devices is determined according to the length of the workpiece. When aligning, the cylinder on the device is pushed out, aligned with the center of the welding seam, the workpiece is pushed forward, the centering block is held up, the workpiece is pressed, the centering device is released, and the centering block is automatically returned to its original position to compress the alignment of the workpiece at the end. The seam position is used as the benchmark, and then the other side to be stitched together. The installation position of the centering device will not affect the entry and exit of the workpiece, and has sufficient rigidity to adapt to the impact of the plate material on the device during centering.

Feeding platform (customer-made, supplier provides drawings)

The feeding platform generally adopts the steel ball type or the rubber wheel method. When the steel ball type is adopted, the upper surface is protected by a steel plate to avoid damage to the steel ball during the sliding process of the workpiece. The effective size of the feeding platform is determined according to the width of the steel plate and the splicing length. Generally, the feeding end: the length is the effective length of the panel, and the width is 6000mm, and the length of the discharge end is the effective length of the panel, and the width is 6000mm. The height of the feeding platform is matched with the panel tooling. For a large number of splices of steel plates at the inlet and outlet ends and the workpiece is thick, it is necessary to increase the feeding and discharging drive mode and extend the width of the feeding and discharging platform, such as the use of electric roller feeding method, or the composite use of steel balls and rollers, etc. .

The controller is the central system to complete the whole process of multi-task longitudinal circumferential seam welding. Adopt stable and reliable PLC programmable control technology platform.

In the actual production welding process, in order to complete the complex welding tasks of different products, the relevant welding parameters and motion parameters should be matched and implemented through a centralized controller. The controller adopts a multi-module centralized control mode, and coordinates and communicates with the relevant welding parameters and motion parameters through programming. The controller has the characteristics of simple programming, intuitive interface, convenient maintenance, and strong anti-interference ability. Considering that the network voltage in the workshop may fluctuate greatly at any time, a large engineering control cabinet is used for the system controller, and the cabinet is arranged for ventilation. , dustproof, heat dissipation, anti-interference and other functions can achieve stable work, and at the same time facilitate monitoring and maintenance. The input voltage of the control cabinet is within 380V or 220V 50Hz ±10%. If it exceeds this range, it is recommended to increase the regulated power supply. The functional modules and switching elements are reasonably installed in the controller through the wire trough. A fan is installed on the top of the control box, which can effectively dissipate heat inside the chassis. There are dust-proof spacers on the edge of the box, which can effectively isolate the dust at the work site, and prevent the dust from entering the control box and depositing on the components and causing the device to fail.
