The prior art polishing process has the following technical defects:

(1) In the polishing process, a polishing device is usually arranged to drive the polishing device to a certain fixed position, so that the polishing operation is carried out on the materials on the conveying line. However, along with the loss of the polishing material on the polishing device, the polishing device arranged at a fixed position polishes the material or has the condition of insufficient polishing stroke, so that the polishing effect is not good enough.

(2) In the polishing process, a large-scale driving structure is required, so that the high efficiency and stability of the overall propelling and withdrawing action strokes of the polishing device and the auxiliary structure thereof are ensured; however, the conventional larger driving mechanism does not have an accurate stroke control effect, so that the propelling stroke of the polishing device is easily larger or insufficient, and the refined material polishing application cannot be met.

If the polishing material is not replaced in time, the polishing effect is poor, and the material is not processed well. In the processing procedure of batch materials, the whole polishing period of the materials is long, and if the polishing material loss in the polishing device is excessive, the situation of a large number of defective products is easily caused, so that serious economic loss is caused.

After the main translation unit 43 is set to the operating position, the translation drive mechanism 422 performs forward or backward movement of a predetermined stroke in accordance with the system program setting or other sensing feedback control setting.

Further, in order to ensure the accuracy of the position of the polishing station of the polishing device, the polishing method applied in the polishing system of the invention further comprises the following steps: in the step (2-2): (2-2-1) sensing the contact pressure of the grinding end face 31 to the grinding face by using a pressure sensor; (2-2-2) according to the feedback contact pressure condition, the linkage translation driving mechanism 422 drives the grinding device to carry out fine adjustment advancing or retreating actions.

Example 3:

in order to effectively and fully enable the grinding device to effectively grind the transition position 132 between the front section position of the material 13 and the special-shaped convex position 131, the grinding system comprises the following working and processing steps:

(3-1) when the polishing surface of the material 13 is a non-flat end surface, pushing a polishing device for polishing driving action towards one side of the position of the material 13, and enabling the polishing end surface 31 to contact with the polishing surface and perform polishing treatment;

(3-2) when the special-shaped convex position 131 of the polishing surface is contacted with the polishing end surface 31, the polishing device is pushed along the conveying direction of the material 13;

(3-3) retreating the side of the polishing device far away from the material 13, enabling the polishing end surface 31 and the special-shaped convex position 131 of the polishing surface to form the matching of the polishing stroke, and polishing the special-shaped convex position 131 of the polishing surface.

When the irregular convex position 131 of the polishing surface is contacted with the polishing end surface 31, the polishing device which continuously works performs pushing action synchronous with the conveying of the material 13, so that the polishing of the transition position 132 can be more fully formed; meanwhile, in the process of polishing the transition position 132, one side of the polishing device, which is far away from the material 13, is retreated, so that the polishing device can effectively clean the transition position 132, from which the protrusion extends, along with the movement of the retreating action; when the grinding end face 31 and the irregular protruding position 131 of the grinding face form the matching condition of the grinding stroke, the grinding device retreats from the end face of the protruding position to perform effective grinding treatment.

In order to prevent the grinding process from being accompanied by the forward advancing process of the material 13, the irregular protrusions entangle the soft and loose grinding material in the grinding device, and the grinding device performs the returning movement in the opposite direction to the conveying direction of the material 13 after the side of the grinding device away from the material 13 is retreated.

When the irregular convex position 131 of the polishing surface is in contact with the polishing end surface 31 to generate entanglement of the polishing material, the entanglement condition is relieved to a certain extent along with the pushing of the polishing device which performs the polishing driving action towards one side of the position of the material 13, and deeper entanglement condition is not generated any more; along with the back-off of the polishing device, the polishing device is enabled to reset and move at a high speed along the opposite conveying direction of the material 13, so that the soft and loose polishing material can be pulled apart from the polishing device, and the fault condition of the polishing device caused by the fact that the subsequent material 13 and the polishing device are hooked and wound due to the depth is avoided.

In the application of the polishing method, the translation driving mechanism 422 as in embodiment 2 can be adopted to control the forward and backward movement of the polishing device; in accordance with practical requirements, a horizontal driving mechanism arranged along the conveying direction of the material 13 is added to the driving part of the grinding device in the grinding driving device 4, so as to meet the application of the grinding device in reciprocating motion relative to the conveying direction of the material 13. The horizontal driving mechanism adopts the transmission form of the air cylinder or the screw rod in the prior art to drive and control the grinding device.

Example 4:

in order to avoid the condition of poor polishing effect caused by loss and untimely replacement of polishing materials, the polishing method further comprises the following steps: arranging at least two mounting stations for mounting and mounting grinding materials on the grinding device; in the processing procedure of polishing, when the loss degree of the polishing material on one dress station reached the predetermined condition, make two dress stations carry out the station and switch the application to the polishing material on another dress station continues to carry out the processing of polishing of material 13.
