Patent Application
20200384665
The present invention relates to a pusher for a planer which when the planner cutter rotates, the drive shaft transmits kinetic energy to the movable control portion to urge the pushing wheel to rotate synchronously, and the drive shaft drives the pushing wheel to rotate slowly via the reduction wheel, hence the wood is pushed slowly and is pressed and pushed by the pushing wheel to be planed automatically.
A conventional planer contains a body on which a press device is arranged, and the conventional planer contains multiple idlers arranged in the press device so that when a wood is pushed through a body, it is pushed by a press force. Furthermore, the wood is pushed forward smoothly.
However, the conventional reading stand has defects as follows:
A wood is pushed by a user, but it cannot be pushed forward to be planned with an even pushing force.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary aspect of the present invention is to provide a pusher for a planer which when the planner cutter rotates, the drive shaft transmits kinetic energy to the movable control portion to urge the pushing wheel to rotate synchronously, and the drive shaft drives the pushing wheel to rotate slowly via the reduction wheel, hence the wood is pushed slowly and is pressed and pushed by the pushing wheel to be planed automatically.
With reference to
The auxiliary rod 54 is supported on an auxiliary abutting block 50 inserted onto a positioning rod 52 which is mounted on a base 51, and a returning spring 53 is fitted on the positioning rod 52 between the base 51 and the auxiliary abutting block 50.
Furthermore, the movable control portion 20 includes a rotary shaft 21 mounted on an upper end of the movable control portion 20 and extending to the movable control portion 20 inwardly. The movable control portion 20 includes a movable pedestal 22 connected with the wheel rod 40 and the actuation rod 44, the movable pedestal 22 has a press post 24 arranged therebelow, the press post 24 has two pressing wheels 24 arranged on a front end and a rear end of the press post 24 respectively, a rear end of the press post 24 abuts against the upper belt 36 between the auxiliary rod 54 and the second receiving portion 41, and a control wheel 25 is biased against the transmitting belt 43 between the guiding portion 42 and the actuation portion 47.
Referring to
Accordingly, when the planer operates, a wood is pushed to the planer 11 from a platform 12, the wood 19 contacts with the pushing wheel 45 of the push member 46, and a user rotates the rotary shaft 21 to control the pushing wheel 45 to press the wood 19. When the planner cutter 13 rotates, the drive shaft 14 transmits kinetic energy to the movable control portion 20 to urge the pushing wheel 45 to rotate synchronously, and the drive shaft 14 drives the pushing wheel 45 to rotate slowly via the reduction wheel 17, thus pushing the wood 19 slowly. The wood 19 is pressed and pushed by the pushing wheel 45 to be planed automatically.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
