Classification and operation safety of sanding machines

⒈ Ordinary sander

Ordinary sanding machine configuration power is small, the frame is relatively light, the model is small and light, the sanding force of the sand roller is relatively small, and it is easy to be damaged by overload operation, but the price is relatively low, suitable for small-scale production use

⒉ Heavy sanding machine

The heavy-duty sander is equipped with high power, heavy frame, large and heavy model, large sanding roller, large sanding force, strong and durable, but the price is about 30% higher than the ordinary type, suitable for large-scale production use

⒊ Overhead sander

The overhead sander is a sander developed and produced for the edge sanding of the board on the basis of the heavy-duty sander. The lifting height of the worktable can be adjusted within the range of 0-650MM, and the lifting range of the customized machine can be more than 1 meter.

⒋ Double-sided sanding machine

The sanding machine that sands both sides at the same time at one time has a complex structure, inconvenient adjustment and high cost, and is only used by large sheet metal processing enterprises.

⒌ Primer Sander

Special sander for sanding primers

Characteristics of sander

⒈ There is a lot of dust in the use environment, and the equipment should be specially designed so that it can run stably without being affected.

⒉ The equipment is precise but the quality of the operator is low. The operation and adjustment of the equipment should be designed as simple and intuitive as possible, and the operation should be trained by specialized personnel.

3. The abrasive belt is relatively easy to deviate, the control abrasive belt system should be stable, and the protection abrasive belt and braking system should be reliable.

⒋The thickness and size of the left and right are uneven, and the lifting system of the worktable is stable.

⒌ The use time is long but the maintenance is relatively poor. Regular maintenance is required to prolong the service life.

Safe operation of sanders

1. The operator must be familiar with the performance, use and operation precautions of the machine before operation. It is strictly forbidden for beginners to operate the machine alone, and non-related personnel are not allowed to approach the machine

2. The operator is not allowed to wear clothes that are easily involved in the machine (such as ties, necklaces, loose clothes, etc.) Those with long hair should curl their hair, pull up or wear a hood, and it is strictly forbidden to wear gloves to operate the machine

3. Do not dismantle the safety device on the sanding machine at will, and do not place any non-work objects on the workbench, such as wrenches, etc., to prevent foreign objects from being stuck and causing damage to the machine

4. Before turning on the power switch, be sure to confirm that all switches are in the OFF position. Before normal operation, check the cleanness and sharpness of the abrasive belt, and check whether the installation direction of the abrasive belt is correct (the arrow on the back of the abrasive belt points in the same direction as the rubber wheel) , Whether the belt specification is suitable, whether the belt swing is moderate, whether the belt is tight, whether the conveyor belt is running on the right track, whether the conveyor belt is tight, whether the planer blade is installed correctly and firmly

5. All protective covers must not be removed before processing. You must first determine whether the size of the wood is within the processing range of the machine, and adjust the correct processing thickness. If the wood is too thick, the conveyor belt will be stuck and broken. This equipment only It can be used for sanding wood with uniform thickness. It cannot be used for horizontal correction of wood bending, and triangular, diamond and arc-shaped wood cannot be processed. Be sure to pay attention to the workpiece without metal and other accessories to avoid damage to the machine.

6. During normal operation, please pay attention to the electric load of the ammeter at any time to prevent the machine from tripping or the sandpaper being overwhelmed due to the overload of the machine, resulting in the cracking or breaking of the abrasive belt.

Correction method: 1. Slow down the speed of the sanding belt; 2. Replace the sandpaper with coarser grit; 3. Raise the position of the rubber wheel or sanding platen to reduce the amount of sanding

7. When the operator is working, once the workpiece is placed on the conveyor belt, his hands should leave immediately, and the workpiece should be evenly placed on the conveyor belt, so that the abrasive belt and the rubber wheel are evenly stressed to avoid unilateral wear and shorten the time between the abrasive belt and the rubber wheel. Applicable life

8. The table top and bottom of the sander can be adjusted using the computer digital lifting controller. The table adjustment is strictly prohibited beyond the adjustment range of the controller, and the table height cannot be manually adjusted without permission, so as to avoid the table tilt or the data error of the lifting controller. The speed of the conveyor belt is infinite Variable speed adjustment, the speed should be adjusted while the machine is running

9. After the work is completed, please be sure to clean up the inside of the machine. When cleaning the interior, be sure to remove the sandpaper. When the cleaning is completed, install the sandpaper again. It is recommended to relax the abrasive belt after the work is completed to avoid the gradual relaxation of the abrasive belt due to long-term tension.

10. New employees must be trained before they can operate the machine, and before the employee is fully familiar with the performance of the machine, there must be an old employee to accompany the work, and do not operate alone. If the operator wants to leave the post due to something, he must shut down the machine first, so as to avoid chatting with others during the operation.
