Description

automatic noodle grinder

technical field

The utility model relates to a grinding machine, in particular to a device for continuously grinding one side or both sides of a small wood chip.

The machines suitable for constant thickness grinding in the woodworking industry are mainly sanding machines, but sanding machines are mainly suitable for large-sized plates, and cannot process small-sized wood blocks. For most small wood products manufacturers, the specifications of materials used in many production processes are extremely small. This is not only because of the small size of the products themselves, but also because the precious mahogany resources are becoming increasingly scarce, so companies must not have a large number of wood products. Use scraps. For example, wooden comb companies use a large number of short wooden blocks with specifications of 30-80*30-50*10-13 (length*width*height, unit mm) to make comb teeth. Some of the above-mentioned wooden blocks are parallel to each other. Some have a certain included angle between the upper and lower sides, and the sanding process not only needs to grind the above short wooden blocks on both sides to meet the thickness-setting requirements, but sometimes also needs to grind the upper and lower sides of the wooden blocks into a certain included angle to reduce the subsequent The processing volume of the process. Since the specification of this part of the material is too small, it is impossible to use a sander for constant thickness grinding, so it can only be manually polished on a flat belt machine and then turned over to polish the other side. In mass production, the operating efficiency is low, the working environment is dusty, the labor intensity of the operator is high, and the wooden blocks are easy to fly off and cause safety accidents if a little careless. Guaranteed dimensional accuracy and shape accuracy after grinding, not to mention batch consistency.

Therefore, there is a need for an automatic continuous processing equipment that can not only realize the double-sided constant thickness grinding of short and small wood blocks, but also realize the fixed angle grinding of short and small wood blocks, so as to solve the problems of low grinding efficiency, poor grinding quality and labor intensity of short and small wood blocks. Big, unsafe problem.
