The end of the clamping bolt 31 abuts against the outer wall of the support plate 2. In order to accurately limit the chain, the present invention sets a limit plate 3 above the support plate 2. The bottom end of the limit plate 3 is connected to the base 1 to ensure that its position is fixed. At the same time, a clamping bolt 31 is installed on the top of the limit plate 3. By tightening the clamping bolt 31, the end of the clamping bolt 31 can abut against the outer wall of the support plate 2, thereby achieving the clamping and limiting effect on the chain. This design not only ensures the stability of the chain during the sharpening process, but also facilitates the adaptive adjustment of chains of different specifications.

[0029] In this embodiment, the pushing component 4 includes a driving bin 41, two movable grooves 44 are provided on one side of the driving bin 41, a push rod 42 is provided on the outer wall of the movable groove 44, a push head 421 is installed at the bottom end of the push rod 42, and a movable rod 43 is connected to the top end of the push rod 42, and the movable rod 43 is slidably matched with the movable groove 44.

[0030] Specifically, a cross bar 45 is provided inside the driving bin 41, and both ends of the cross bar 45 are hinged to the moving rod 43, one end of the cross bar 45 is connected to an eccentric wheel 47 through a connecting rod 46, and the eccentric wheel 47 is driven by a motor, and the eccentric hole of the eccentric wheel 47 is hinged to one end of the connecting rod 46, and one end of the connecting rod 46 is hinged to one end of the moving rod 43. The pushing assembly 4 is one of the core components in the present invention, which is responsible for pushing the chain to perform the sharpening action. Its specific structure includes components such as a driving bin 41, a moving groove 44, a push rod 42, and a moving rod 43. A driving mechanism, such as a motor and a transmission mechanism, is provided inside the driving bin 41 to provide a driving force.

This design enables the present invention to adapt to the sharpening operation of chains of different specifications and shapes.

[0032] Furthermore, the outer wall of the guide positioning column 7 is provided with an external thread, the surface of the bracket 5 is provided with a through hole, and a guide groove 8 is installed on the top of the pushing component 4. The guide positioning column 7 passes through the through hole and the bottom end slides with the guide groove 8, ensuring the stability and accuracy of the bracket 5 during the movement, and avoiding the impact of vibration or displacement on the sharpening effect.

[0033] Further, the grinding wheel assembly 9 includes a motor 91, a grinding wheel 92 is installed at the output end of the motor 91, a grinding wheel cover 93 is provided on the outside of the grinding wheel 92, a support plate 94 is hinged on the back of the grinding wheel cover 93, and the top of the support plate 94 is connected to one end of the bracket 5, and the grinding wheel assembly 9 is used to perform actual sharpening operations on the chain. The grinding wheel assembly 9 includes components such as a motor 91, a grinding wheel 92, and a grinding wheel cover 93. The output end of the motor 91 is installed with a grinding wheel 92, and the grinding wheel 92 is driven by the motor 91 to rotate at a high speed, thereby grinding the chain. The grinding wheel cover 93 is sleeved on the outside of the grinding wheel 92 to play a protective and dustproof role. At the same time, the back of the grinding wheel cover 93 is hinged with a support plate 94, and the top of the support plate 94 is connected to one end of the bracket 5 to ensure that the position of the grinding wheel assembly 9 is fixed and reliable.

[0034] Furthermore, an angle adjustment screw 95 is installed on the upper cover of the support plate 94, and the top end of the angle adjustment screw 95 abuts against the outer wall of the motor 91. By rotating the angle adjustment screw 95, the inclination angle of the motor 91 and the grinding wheel 92 can be adjusted, so as to adapt to the sharpening operation of chains with different angles and shapes. This design greatly improves the practicality and flexibility of the present invention.

[0035] Furthermore, the front shape of the pusher head 421 fits the outside of the chain, and the rear of the pusher head 421 is an outwardly protruding arc structure.

[0036] Furthermore, the front and rear surfaces of the grinding wheel cover are hollow structures, and the mounting rods at the hollow parts are provided with dust-proof nets, which have a certain dust-proof effect.

[0037] When the automatic sharpening machine for felling chains of the present invention is used, the felling chain to be sharpened is first mounted on the support plate 2 and limited by the limit plate 3. The clamping bolt 31 is tightened so that its end abuts against the outer wall of the support plate 2, thereby achieving the clamping and limiting effect on the chain and ensuring the stability of the chain during the sharpening process.

[0038] Then, the motor in the pushing assembly 4 is started to drive the eccentric wheel 47 to rotate. The eccentric hole of the eccentric wheel 47 is connected to one end of the cross bar 45 through the connecting rod 46, and the two ends of the cross bar 45 are hinged to the moving rod 43. As the eccentric wheel 47 rotates, the connecting rod 46 drives the cross bar 45 to reciprocate, thereby causing the moving rod 43 to slide in the moving groove 44. The sliding of the moving rod 43 drives the push rod 42 to reciprocate, and the push head 421 at the bottom end of the push rod 42 directly contacts and pushes the chain to move on the support plate 2.

[0039] When the chain is pushed to the position of the grinding wheel assembly 9, the motor 91 is started to rotate the grinding wheel 92 at a high speed. The grinding wheel 92 contacts and grinds the cutting edge of the chain, thereby removing the blunt part and restoring the sharpness.

[0040] During the sharpening process, the bracket 5 is fixed to the base 1 through the center column 6, and its height and position are adjusted by adjusting the nut to adapt to chains of different specifications and shapes. The guide positioning column 7 passes through the through hole set on the surface of the bracket 5 and slides with the guide groove 8 on the top of the push component 4 to ensure the stability and accuracy of the bracket 5 during movement.

[0041] When the inclination angle of the motor 91 and the grinding wheel 92 needs to be adjusted, the angle adjustment screw 95 on the support plate 94 can be rotated so that its top end abuts against the outer wall of the motor 91, thereby adjusting the inclination angle of the motor 91 and the grinding wheel 92 to adapt to the sharpening operation of chains of different angles and shapes.

[0042] During the sharpening process, the grinding wheel cover 93 plays a protective and dustproof role. Its front and rear surfaces are hollow structures and are equipped with a dustproof net to prevent the dust generated during the grinding process from splashing.
