Technical Field

The application relates to the field of grinding equipment, in particular to a saw chain grinding machine.

Background

The chain saw hole making machine is a device which is widely used in the fields of lumbering and timber making and the like and utilizes the movement of a cutter on a saw chain to complete the shearing action of materials when the saw chain rotates. After long-term use, the blade of the saw chain cutter and the blade surface are abraded to cause the blade to become smooth, the shearing resistance is increased to cause the shearing efficiency and effect to be obviously reduced, therefore, the saw chain cutter is generally ground by a chain grinding machine to restore the blade to be sharp. The existing chain grinding machine can only grind a single cutter on one saw chain at one time, and the grinding efficiency is extremely low. In addition, for the tapping machine with a plurality of saw chains, when the saw chains are ground, factors such as grinding depth and knife face angle are changed easily due to installation errors caused by saw chain replacement or slight angle change of a grinding device, and therefore differences exist between every two saw chains after grinding, and the using effect of the tapping machine is influenced on the contrary.

SUMMERY OF THE UTILITY MODEL

In order to solve the grinding efficiency that chain grinding machine exists among the prior art low, to having many saw chain tapping machines, be difficult to guarantee that saw chain cutter keeps unanimous problem after the grinding, this application provides a saw chain grinding machine that can carry out the grinding to the cutter on a plurality of saw chains simultaneously.

In order to achieve the purpose, the technical scheme adopted by the application is as follows:

a saw chain grinding machine comprises a grinding device for grinding cutters on saw chains and a chain conveying device for fixing the saw chains, wherein the chain conveying device tensions a plurality of saw chains in parallel and rotates the saw chains to enable the cutters on the parallel saw chains to move to a grinding position to be ground simultaneously.

After the saw chain is used for a long time, the cutting resistance is easy to increase due to cutter abrasion, the cutting surface is rough, and other negative effects are easily caused, but the cost for directly replacing the saw chain is high, so that in an actual application scene, a chain grinder is often used for grinding cutters of the saw chain, the cutting edges of the cutters are recovered to be sharp, and the cutter surfaces are recovered to be smooth and then are continuously used. The existing saw chain grinding machine has the disadvantages that after a single saw chain is fixed in a chain conveying device, a grinding device is used for grinding cutters in sequence, and the working efficiency is low. In some chain-type hole opening machines, the hole opening work is completed by means of the parallel combined action of a plurality of saw chains, the saw chains are ground one by the chain grinding machine, the efficiency is low, and the cutter after the grinding of the saw chains on the final hole opening machine is different due to slight change of the installation angle or the grinding angle when the ground saw chains are replaced, so that the using effect of the hole opening machine is influenced.
