A hydraulic rod 310 is slidably installed on the inner wall of the hydraulic cylinder 309. When the water in the hydraulic cylinder 309 and the hydraulic rod 310 squeeze the water in the hydraulic cylinder 309, the hydraulic rod 310 will not move in the hydraulic cylinder 309 due to the characteristic that water is difficult to be compressed. A water hole 311 is opened at the upper end of the hydraulic cylinder 309, and the water hole 311 is arranged The positions are symmetrically staggered on the outer wall of the hydraulic cylinder 309, so that when the hydraulic cylinder 309 is restored to its original state, it is more convenient for water to flow back into the hydraulic cylinder 309 through the water hole 311 under the action of air pressure. A pressure relief ring 312 is slidably sleeved on the outer wall of the hydraulic cylinder 309 near the water hole 311, and a sealing ring is provided on the upper end of the pressure relief ring 312 (not shown in the figure).

A control rod 315 is fixedly installed on the outer wall of the pressure relief ring 312, and a stop rod 316 is fixedly installed on the inner wall of the cutting frame 301 close to the control rod 315. When the pressure relief ring 312 moves downward, the stop rod 316 blocks the movement of the control rod 315, so that the pressure relief ring 312 starts to move upward. The chamber 313 set in the pressure relief ring 312 is connected to the water passage. The hole 311 is connected, so that the water in the hydraulic cylinder 309 enters the pressure relief ring 312, and the air pressure in the pressure relief ring 312 begins to increase, so that the hydraulic rod 310 moves to squeeze the gas, so that when the hydraulic rod 310 cuts the pencil and cuts to the pencil lead position, the pressure relief ring 312 moves, so that the force of the hydraulic rod 310 cutting the pencil lead becomes smaller. When the pencil lead is disconnected, the air pressure in the chamber 313 reaches a certain level, and the air pressure pushes the pressure of the hydraulic rod 310 to restore the cutting force during hydraulic cutting.

[0040] See also Figures 1 to 7 , sliding rails 317 are symmetrically installed at both ends of the cutting frame 301, and sliding blocks 318 are slidably installed on the side ends of the sliding rails 317, and a cutting knife 319 is fixedly installed between the sliding blocks 318, and the lower end of the cutting knife 319 is set to be in a flat state on one side and an inclined knife shape on the other end, so that the cutting knife 319 cuts the remaining pencils to maintain a plane, and the upper end of the cutting knife 319 is fixedly installed with a mounting block 320, and the end of the hydraulic rod 310 away from the hydraulic cylinder 309 is rotatably installed on the upper end of the mounting block 320, so that the hydraulic rod 310 drives the hydraulic rod 310 to rotate more conveniently during the rotation process.

[0041] See also Figures 1 to 7The cutting frame 301 is slidably mounted with a mounting frame 324 at the lower end near the cutting knife 319, and a return spring 321 is fixedly mounted between the mounting frame 324 and the cutting frame 301. When the cutting knife 319 pushes the mounting frame 324 to move, the return spring 321 pulls the mounting frame 324 to provide a force for lateral movement of the mounting frame 324. The mounting frame 324 is fixedly mounted with a mounting telescopic rod 322 at the upper end near the cutting knife 319, and the above-mentioned mounting telescopic rod 322 is an existing The telescopic rod 322 is controlled by a spring, and a whetstone 323 is fixedly installed on the upper end of the telescopic rod 322.

A fixed retractor 416 is fixedly installed on the lower end of the collecting tank 410. The above-mentioned fixture is a heat melter in the prior art, and the output end of the heat melter is arranged to be a retractable heat melt head. After the pencil is wrapped by the packing rope 413, the connection of the packing tape is cut and fused, so that the pencil packaging is more convenient.

[0044] The working principle of the present invention is as follows: when the processed pencils need to be cut and packaged, the processed pencils are placed in the placement groove 203 provided on the placement plate 202, the spring telescopic rod 204 drives the fixed plate 205 to descend, the rolling wheel 209 and the guide wheel 210 abut against the surface of the wall, the driving motor 207 is started, the rotating rod 208 starts to rotate, the rolling wheel 209 drives the pencils to start moving, and when all the pencils are inserted into the rubber ring provided on the limiting plate 404;

[0045] When the pencil moves to a suitable length, the cutting motor 302 is started, so that the cutting disc 304 drives the rotating cylinder 307 to start rotating, and the linkage rod 308 drives the hydraulic cylinder 309 to start descending, so that the hydraulic rod 310 pushes the cutting knife 319 to descend to cut the pencil pen wood. When the cutting knife 319 cuts the pen, the blocking rod 316 blocks the movement of the control rod 315, and the pressure relief ring 312 starts to slide on the outer wall of the hydraulic cylinder 309. When the cutting knife 319 moves to the position of the pencil lead, the chamber 313 in the pressure relief ring 312 moves to the water hole 311 set in the hydraulic cylinder 309. The water hole 311 connects the chamber 313 with the hydraulic cylinder 309, and the water in the hydraulic cylinder 309 enters the chamber 313. The water in the hydraulic cylinder 309 enters the chamber 313 to squeeze the air in the chamber 313, and the water squeezes the air in the chamber 313, so that the hydraulic rod 310 contracts. The hydraulic rod 310 pushes the water in the hydraulic cylinder 309 to enter the chamber 313 to squeeze the air in the chamber 313, and the cutter 319 cuts the pencil lead. The force of the cutter 319 to cut the pencil lead is reduced, so as to avoid excessive force in cutting the pencil lead in the process of cutting the pencil, resulting in the pencil lead being broken.

[0046] After the pencil is cut, the electric telescopic rod 402 is started, and the winding spring 408 pushes the limit plate 404 to start rotating, so that the pencil inserted into the limit plate 404 starts rotating. After the pencil moves to the collecting groove 410, the pencil is separated from the limit plate 404, and the pencil moves to the bottom of the collecting groove 410. The electric packer 412 is started to make the packing rope 413 wrap around the pencil. After the packing rope 413 wraps and fixes the pencil, the fixer is started to cut, heat and fuse the position where the packing rope 413 is attached, so that the pencil packaging is more convenient.
