Technical Field

The utility model relates to a timber rotary-cut apparatus technical field, concretely relates to long timber log has card peeler.

Background

The processing of wood requires that bark is firstly stripped and then deep processing is carried out, and the stripping method of the bark generally comprises two methods of manual processing and mechanical processing; the manual bark cutting consumes a large amount of manpower, the processing efficiency is low, the bark is cleaned to generate a large number of flaws, the quality of a finished product is poor, and the requirement of modern people for high-quality life cannot be met; the existing main stream method is to remove bark by machining, and the rotary cutter adopted by the existing machining generally consists of a frame, a static cutter head and a feeding mechanism with a movable cutter head, wherein the feeding mechanism moves left and right relatively on the frame under the action of a gear rack and a gear motor. Due to the cooperation gap between the gear rack and the gear motor, the distance between the two ends of the static cutter disc and the movable cutter disc has errors, and the round log is subjected to rotary cutting to have a big end and a small end. Therefore, improvements are needed.

The chinese national intellectual property office discloses a utility model patent that patent number is ZL2018207833024, this scheme includes the base etc., and a plurality of support frames all are located the base bottom, and a plurality of protection shields are all on a support frame, and the mount is fixed on the movable plate, and the ventilation hole is on the rotary-cut case, and wherein the rotary-cut case includes box etc. the fan is located the top of the inside of box, and a plurality of rotary-cut saw bits are located the inside both sides of box respectively, leading board is located the front of box, and rotatory jogged joint is on leading board, and a plurality of blades all are located the rotatory downthehole. The utility model discloses a fix the material on the mount, rethread movable plate removes by oneself and carries out the rotary-cut to the material, and whole mechanization has improved work efficiency, has reduced operating time, has saved manpower and materials, and cleaning equipment is more convenient.

However, with the use of the mechanism in production, the mechanism can achieve the above effects to a certain extent, but with the advancement of social science and technology, the mechanism and the existing advanced equipment can not obviously meet the requirements of the current environment, and are mainly embodied in the following points:

1. as is known, after a large log is cut, the diameter of the large log is larger than 50cm, and when the large log is rotatably cut, the large log is limited by the structure of the device, so that the device cannot be used for positioning and rotatably cutting the large-diameter log.

2. After a series of transportation, the bark on the surface of the log can be rotten; this just makes when carrying out rotary-cut to this row of log, need carry out the preliminary treatment in advance with rotten region or bark on log top layer, but the device adds man-hour to this type of log, because waste material and certified products are in a guide passageway, for convenient subsequent processing for still need sort out the waste material from the certified products, when having improved the labour, still reduced work efficiency.

3. Although the device can be used for rounding and rotary-cutting round logs, the device can be used for processing long round logs, and the round logs cannot vibrate due to the weight of the round logs; however, when a log having a short length and an irregular shape is machined, the shape of the log is limited, and thus effective rotary cutting cannot be performed.

4. When the wood chips are used for producing the plates, the width requirements of the wood chips are different according to different plate requirements, if the rotary cut width is narrow, the overlapping of the adjacent wood chips can be met, and if the width of the wood chips is wider, the wood chips are required to be subjected to secondary shearing; as is known, the collected wood chips are processed again, which inevitably results in inconvenient feeding and reduced yield of the wood chips.
