Description

Technical Field

[0001] The utility model relates to the technical field of peeling machines, in particular to a wood peeling machine with a protection function. Background Art

[0002] Peeling machine is a thin wood board cutting production equipment. The wood cut into cylindrical shape is put into the peeling machine. The wood is positioned and driven by three columnar positioning rollers, and the relative movement between the cutting board and the wood is coordinated to realize peeling on the surface of the wood.

[0003] Most of the existing peeling machines use mechanical transmission to transport the wood to the top of the peeling machine when feeding, and feed from top to bottom. The wood falls from the feeding point into the space between three columnar positioning rollers, and finally the peeling operation is achieved through the push of the hydraulic device and the proximity of the cutting board. However, in actual use of the above equipment, when the wood is fed from a high place, due to the weight of the wood itself, it is easy to generate a large impact force on the positioning roller when it falls from above to the positioning roller. In the long run, it is easy to cause more wear and damage to the positioning roller, affecting the normal operation of the peeling machine. In view of this, we propose a wood peeling machine with a protective function. Utility Model Content

[0024] In one embodiment of the utility model, a transmission cavity is opened on the arc-shaped outer wall of the positioning roller 8, a transmission block 10 is slidably installed on the inner wall of the transmission cavity, a protection spring 11 is fixedly connected between the bottom outer wall of the transmission block 10 and the bottom inner wall of the transmission cavity, a connecting rod 12 is rotatably installed on the bottom inner wall of the transmission block 10, a contact ball 14 is fixedly installed on the top of the connecting rod 12, a volute spring 13 is sleeved on the arc-shaped outer wall of the connecting rod 12, a spiral groove 15 is opened on the spherical surface of the contact ball 14, and a magnetic block 16 is fixedly installed on the bottom end of the side wall of the transmission block 10.

[0025] Furthermore, the feeding mechanism 2 includes a fixed plate fixedly mounted on the base 1 and a motor arranged on the side, the output end of the motor is fixedly connected to the transmission roller and the conveyor belt connected to the arc-shaped outer wall of the transmission roller. Through the setting of the feeding mechanism 2, the thin plate cut by the rotary cutter can be transported to the right for collection by the staff, and the auxiliary mechanism 3 includes a column fixedly mounted on the base 1 and an auxiliary roller arranged on the side of the column, and there are two groups of auxiliary rollers, and the two groups of auxiliary rollers are vertically installed on the side of the column. At the same time, the two groups of auxiliary rollers are connected to the output end of the motor installed on the side of the column through a chain, so that they can cooperate with the positioning roller 8 to transmit the wood, so that it can rotate in the interval formed between the two groups of auxiliary rollers and the positioning roller 8.

[0026] In addition, a protrusion is fixedly installed at the bottom end of the sliding column 6, and a rectangular sliding groove adapted to the protrusion is opened on the upper surface of the base 1, so that when the hydraulic rod 5 is started, the sliding column 6 will move horizontally along the upper surface of the base 1, thereby controlling the size of the interval enclosed by the positioning roller 8 and the auxiliary roller, so that during the peeling of the wood, the positioning roller 8 always keeps in close contact with the surface of the wood, thereby assisting the cutting board 9 to peel it.

[0027] Specifically, the size of the transmission block 10 is adapted to the size of the transmission cavity. At the same time, a limiting groove adapted to the size of the magnetic block 16 is opened on the inner wall of the transmission cavity, and a magnetic sheet with the same magnetic properties as the magnetic block 16 is fixedly installed on the top inner wall of the limiting groove, so that when the magnetic block 16 moves upward in the vertical direction along the limiting groove, the repulsive force between the magnetic sheet and the magnetic block 16 can suppress the upward movement speed of the transmission block 10, so as to avoid the elastic force of the protective spring 11 affecting the transmission block 10 to bounce upward quickly after being compressed, causing the wood on the surface of the positioning roller 8 to jump repeatedly.

[0028] In the present invention, when in use, the hydraulic rod 5 is started to drive the sliding column 6 to move toward the side away from the auxiliary mechanism 3 to expose the space between the positioning roller 8 and the auxiliary roller. At this time, the wood is put into the space between the positioning roller 8 and the auxiliary roller in cooperation with the external feeding equipment. At this time, the hydraulic rod 5 is controlled to push the sliding column 6 to move slowly toward the side of the auxiliary mechanism 3, and at the same time, the motors arranged in the auxiliary mechanism 3 and the feeding mechanism 2 and the driving motor 7 arranged on the side of the sliding column 6 are started to drive the positioning roller 8 and the auxiliary roller to rotate, so as to realize the continuous rolling of the wood, and cooperate with the cutting board 9 It is pressed against the surface of the wood to realize the peeling of the wood. At the same time, by providing a protection mechanism and cooperating with the protection spring 11, when the wood falls and contacts the positioning roller 8, the transmission block 10 and the contact ball 14 can reduce the impact of the wood, and by providing a number of protection mechanisms in a spiral array on the arc-shaped outer wall of the positioning roller 8, the positioning roller 8 can provide a certain protection effect on the impact of the wood regardless of any rotation angle, thereby preventing the positioning roller 8 from being bent or damaged due to long-term impact, thereby affecting the normal operation of the equipment.
