Description

Disc chipper with material pressing system

[ technical field ] A method for producing a semiconductor device

The invention belongs to the technical field of wood processing equipment, and particularly relates to a disc chipper with a material pressing system.

[ background of the invention ]

A chipping machine, also called a wood slicing machine, belongs to one of wood processing series devices, and is widely applied to material preparation working sections in the production processes of textile, papermaking, pulping, artificial boards and other industries. The chipping machine can be divided into a drum type chipping machine and a disc type chipping machine according to the mechanical structure, and the working principle is as follows: when the wood contacts the fly cutter, the wood is cut along with the high-speed rotation of the cutter head, and the cut wood chips are sent out by the high-speed steam flow generated by the fan blades on the cutter head.

The invention patent ZL201610264304.8 discloses a disc type material chipping machine which comprises a rack, wherein a cutter disc driven by a driving mechanism is arranged at one side end of the upper part of the rack, the cutter disc is vertically arranged above the rack, a material guide channel is obliquely arranged at the side edge of the cutter disc, and wood is pushed into a material inlet through the material guide channel. Because the cutter on the cutter head must keep a certain inclination angle with the wood to cut the wood (like a pencil), and the cutter head is vertically arranged on the machine frame, the material guide channel must have a certain included angle with the cutter head. The inclined material guide channel needs manual feeding, the automation degree is low, and the working efficiency is low.

[ detailed description ] embodiments

As shown in fig. 1 to 3, a disc chipper comprises a frame 1, a cutter head 2 driven by a driving mechanism is arranged above the frame 1, and the cutter head 2 is arranged in a cutter head box 3 (fig. 1 is provided with a part of the cutter head box 3 removed for easy understanding, and the cutter head 2 is actually completely covered by the cutter head box 3); the cutter head box 3 and the vertical direction form an inclined angle of 25-60 degrees. The bottom of the cutter head box 3 is provided with a feeding hole 4. The feed port 4 is butted with a horizontal material conveying belt 5; a material discharging mechanism (not shown) is arranged below the cutter head box 3.

A crawler climbing pressing mechanism 6 is obliquely arranged between the horizontal material conveying belt 5 and the cutter head 2.

The crawler climbing pressing mechanism 6 comprises a motor 61, a first roller shaft 62, a second roller shaft 63 and a crawler 64.

A pair of optical axes 65 is obliquely arranged on the frame 1 between the cutter head box 3 and the horizontal material conveying belt 5.

Both sides of the motor 61, the first roller shaft 62, and the second roller shaft 63 are bridged on the optical axis 65 by linear bearings 66 and slide thereon.

The first roller shaft 62 and the second roller shaft 63 are connected by a crawler belt 64, and the output shaft of the motor 61 is connected to the first roller shaft 62 through a transmission 67.

The motor 61 drives the first roller 62 to rotate, and the first roller 62 drives the second roller 63 to rotate through the crawler belt 64.

When the material 100 on the horizontal material conveying belt 5 is conveyed to the feeding hole 4, firstly the material 100 touches the caterpillar track 64, the rotating caterpillar track 64 can drive the whole caterpillar track to climb the pressing mechanism 6 and move up along the optical axis 65 until the lowermost caterpillar track 64 falls right above the material 100, and when the height of the material 100 becomes low, the caterpillar track climbing pressing mechanism 6 slides down due to the action of gravity and still presses the material 100.

The track 64 may be comprised of a plurality of chains having serrated blades.

Because the cutter head 1 and the horizontal material conveying belt 5 form a specific angle, the horizontal material conveying belt 5 is away from the cutting position by a certain distance (approximately about 10-30 cm), and in order to ensure that the distance of 3-10 cm away from the cutting position has a downward pressure, a pressure plate 7 is arranged at the position, namely the crawler climbing pressure mechanism 6 is also connected with the pressure plate 7, two sides of the tail part of the pressure plate 7 are positioned above the second roller 63 and erected on the optical axis 65 through a linear bearing 66, and the head part of the pressure plate 7 extends to the lower part of the second roller 63. When the material 100 on the horizontal material conveying belt 5 is conveyed to the feeding hole 4, firstly the rotating track 64 touches the track 64, the rotating track 64 can drive the whole track to climb the pressing mechanism 6 to move upwards along the optical axis 65, and since the linear bearings on both sides of the tail of the pressing plate 7 are located above the linear bearings on both sides of the second roller 63, the second roller 63 moves upwards to support the pressing plate 7 to move upwards, and the head of the pressing plate 7 below the second roller 63 can still press the lower material. When the material that the front end is close to feed inlet 4 department is high, and the material that the rear end track climbed swager mechanism 6's the material department of pressing is low, this moment, presses flitch 7 still can keep pressing the material effect, and the track of rear end climbs swager mechanism 6 gliding simultaneously, does not influence the front end and presses the material. The horizontal material conveying belt 5 of the chipper is a small distance away from the cutting position, and the crawler climbing and pressing mechanism 6 of the invention also has forward conveying force on the material in the upward climbing process. In addition, the material pressing plate 7 is lifted while the crawler belt 64 ascends, so that the phenomenon of material blocking is avoided.

As shown in fig. 4, a plurality of circular arc cutters 11 are arranged at intervals on the cutter head 1 in this embodiment, a bed knife 41 is arranged at the lower end of the feed port 4, and the bed knife 41 is circular arc. As shown in fig. 5, the circular bottom knife 41 and the circular cutting knife 11 can achieve better slicing effect during cutting. The circular arc-shaped bed knife and the cutter form certain holding force on the materials, the materials cannot move towards one side to be stacked and then broken, and the shape of the sliced finished product is regular.

According to the wood chipping machine, the two-stage pressing system (the track climbing pressing mechanism and the pressing plate) is arranged above the position as close as possible to the shearing position, so that even if a short wood raw material enters, pressure for preventing the wood from warping and jumping or being broken exists above the wood in the chipping process. The invention also changes the traditional mode of the cutter and the bottom knife, and changes the original linear mode of the bottom knife and the cutter into the circular arc mode, thereby effectively solving the problem that wood moves to one side and is stacked due to shearing force in the cutting process.

The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
