Sanding machine fault repair, debugging and maintenance


Everyone is familiar with the metal sanding machine. It is a device that uses sand belts for sanding (or grinding) processing of various boards, wooden workpieces, and woodworking handicrafts. Metal sanding machines are widely used in wood-based panels and furniture industries, with large demand and many types, and have developed rapidly in recent years.

The metal sanding machine can be used for the dimensional accuracy control of the workpiece, and can also be used to control the surface roughness of the workpiece; it is suitable for processing workpieces with wide materials and narrow workpieces; processing various planes, processing various curved surfaces; suitable for For mass production, it can also be processed in small batches.

Metal sanders often fail due to the processing environment, high dust, and high sawdust. Everyone learns some emergency treatment methods, maintenance and repair methods, which are very useful to everyone.

1. Belt deviation


Usually caused by improper adjustment, the normal belt swing range is 15~20mm, the frequency is 25~35 times, and the swing speed should be the same in the meeting! If it is in an abnormal state, a phase may appear over time!

A metal sanding machine factory is a specialized facility where machines that smooth metal surfaces are manufactured. The most common type of metal sanding machine is the belt sander, which uses a continuous loop of abrasive-coated fabric to remove paint, rust, and other materials from metal surfaces. Other types of metal sanding machines include disc sanders, orbital sanders, and hand-held power tools with abrasive attachments. Metal sanding machine factories typically have large industrial belt sanders and other heavy equipment to create smooth finishes on metal surfaces.

A metal sanding machine factory is a type of manufacturing facility that produces metal sanding machines. These machines are used to sand down metal surfaces to create a smooth, even finish. The factory will generally have a variety of different models and sizes of machines to accommodate the different needs of its customers.


2. Sand belt fracture


The main reason for the fracture of the abrasive belt is that the limit switch of the belt running belt is damaged, and it cannot be stopped in time! The blunt abrasive belt has not been replaced in time, or the cutting load is large, or hard objects are encountered during the sanding process, or the quality of the abrasive belt itself is caused by a problem! The abrasive belt should be avoided as far as possible, so as not to cause safety hazards such as fire!

When the ammeter is found to be abnormal, the abrasive belt should be checked or replaced in time! And check whether there are foreign objects in the sanding plate, whether there are debris in the conveyor belt, etc...


3. Feed deviation


The deviation of the feed is mostly caused by damage to the pressing rod, or slippage and rebound caused by insufficient adjustment. In the adjustment of the metal sander, it is required to adjust the back pressure spring of the upper conveying roller to two-thirds (the remaining one-third ), the interval between the upper conveying roller and the lower conveying roller should be 1.5mm or 1mm less than the thickness of the passing slab, otherwise it will cause the slab to deviate or slip. In severe cases, it will cause rebound, which may injure personal safety.

If the bearing of the pressing roller is locked, or the rubber surface of the pressing roller is damaged, the bearing or pressing roller should be replaced in time

4. Change the abrasive belt, the cutting size changes


When the cantilever of the metal sander is loosened or locked, the position fluctuates greatly, and it should normally be within 0.5mm. If it is too large, when the locking block locks the cantilever, the difference in the locking force will cause a difference in the repeatability of the cantilever, causing the size of the sanding plate to fluctuate, which directly affects the sanding accuracy of the metal sander. When the cantilever error is too large (more than 0.5mm), the fixing bolts of the locking block should be unscrewed and adjusted properly. At the same time, when the abrasive belt is replaced, the locking force of the locking block should be consistent.


5. The conveyor belt is intermittently conveyed or not conveyed


During work, the above situation cannot generally be observed. It can only be found when the car is empty. The reason is that the worm gear is partially or completely worn during the deceleration of the worm gear that transmits power. Although it will not affect the work, other worm gears will shorten the life due to the increased workload and cause greater losses. Therefore, as soon as this condition is found, it should be replaced immediately.

A metal sanding machine wholesaler is a company that sells metal sanding machines to other companies. These machines are used to remove paint, rust, or other materials from metal surfaces. The wholesaler may also offer services such as machine repair and maintenance.

Disc Sanders are less common, but they are very useful for finishing workpieces with irregular surfaces.


6. Abnormal vibration of bearing seat


Under normal circumstances, the vibration of the main bearing seat is very small, and an experienced operator can judge whether it is normal by touching it. Generally, there is no condition to measure it with an instrument on site, but it can be judged by comparing it with other bearing seats, or it can be judged from the surface of the sanding board. bad to judge. When there is abnormal vibration of the bearing seat, it can be considered that there are two reasons. One is that the bearing is damaged, just replace the bearing, and the other is that the contact roller is worn out and lost, and the original dynamic balance is destroyed, resulting in abnormal vibration. This situation must be Remove the sand roller for maintenance
