1300mm primer sanding machine

    The 1300mm primer sanding machine from Jixingyuan is a specially designed high-performance equipment used for polishing primer after painting. It is particularly suitable for various flat products, especially flat wooden furniture. After being processed by this machine, the painted surface becomes smooth without white edges, ensuring first-class smoothness.

The machine adopts a heavy-duty body made of welded steel plate bent parts, which has significant stability during operation. It has undergone annealing treatment, effectively preventing deformation over time and ensuring long-term reliable use.

    The sand belt operation adopts imported frequency converter for variable speed control. This enables it to adapt to the unique characteristics of different types of paints, ensuring optimal sanding performance. The alignment of the sand belt is automatically controlled by a photoelectric system, which maintains precise tracking and prevents misalignment during operation.

    The feeding speed is regulated by a stepless speed controller to achieve smooth and precise control. The workbench is lifted and lowered by a four column lifting structure to ensure stable operation, minimal movement, and high precision.

    The running rubber roller is made of 25SH rubber, which has excellent elasticity. They are very effective in eliminating horizontal grain white edges, with high accuracy and long service life. Optional polishing wheel with variable speed control and adjustable height. This feature further enhances the machine's ability to remove lateral particles, thereby achieving a flawless surface finish.

    The conveyor belt is a 3mm thick imported high-strength belt, which is wear-resistant and durable. It is equipped with an automatic belt deviation correction mechanism, which continuously adjusts the running trajectory of the conveyor belt during operation without manual intervention.

    The sanding belt motor is a part of the variable speed control system. The operator can easily change the linear speed of the sanding belt by adjusting the speed control knob on the control panel. The height adjustment of the workbench can be achieved through specific operating methods, and the digital thickness gauge provides accurate readings. To fine tune the slight displacement, the handwheel on the lifting motor shaft can be rotated.

    The conveying and feeding device consists of a conveyor belt on the workbench, a continuously variable transmission, a manual tension adjustment mechanism, a cylinder, and an automatic centering system with sensor control valves. By manipulating the gear lever on the continuously variable transmission, the feed speed can be easily adjusted.

    Safety is the top priority of this machine. There is an emergency stop button (self-locking) on the control panel, and two photoelectric switches are installed on the left and right sides of the sanding machine frame. When the pressure in the pneumatic system is insufficient, the pressure relay will be activated, and a disc brake is installed on the motor pulley to ensure rapid braking and stopping in emergency situations. In addition, the fault indicator light on the control panel will remind the operator to pay attention to issues such as low air pressure and sand belt deviation.

    The machine also has a unique dust collection device that can significantly improve dust collection efficiency and maintain a clean working environment.

    In terms of technical specifications, this model is JXR-R-1300. Its effective processing width range is 30 to 1300 millimeters, and it can handle boards coated with primer with a thickness of 2 to 110 millimeters. The minimum processing length is 300mm, and the conveyor speed can be adjusted between 5-15m/min.
