Abstract

The utility model provides a roller shaft structure of a non-clamping rotary cutter. The roller shaft structure comprises a machine base, a first roller shaft body, a second roller shaft body, a third roller shaft body and a roller shaft body bracket for connecting the roller shaft bodies and the machine base. The roller shaft bodies are of independent complete structures, a roller shaft body bracket groove is formed in the middle of each roller shaft body, and a plurality of grooves are formed in the first roller shaft body and the second roller shaft body respectively and are distributed in a staggered mode, namely the positions of the grooves on the first roller shaft bodies correspond to the positions having no grooves on the second roller shaft body. One side of the roller shaft body bracket is a straight edge and is fixed on the base, and the other side of the roller shaft body bracket is a C-shaped groove and matched with the roller shaft body bracket. The rotary shaft structure of the non-clamping rotary cutter can effectively overcome the shortcomings that the existing roller shaft is large in error and low in working accuracy and needs much maintenance due to sectioned connection, greatly prolongs service life, improves work efficiency and reduces production cost.

Description

The roll shaft structure of card-less rotary cutter

Technical field

The utility model relates to the wood processing machinery technical field, relates in particular to a kind of roll shaft structure of card-less rotary cutter.

Background technology

Most widely used in the wood processing machinery is card-less rotary cutter, but at present, the single roll shaft axis body of this peeler is divided into three sections, two sections interface has bearing to connect, shown in figure-1, because be that segmentation connects, influence the roll shaft precision, when timber is moist, can ooze out moisture in the rotary-cut process; During the drying of wood, be easy to generate chip in the rotary-cut process, all can shorten bearing service life, fault rate height, and maintenance trouble, inefficiency increases production cost.

Given this, be necessary to provide a kind of roll shaft structure of new card-less rotary cutter to solve above-mentioned technical problem.

Summary of the invention

The technical problem that the utility model solves is to provide a kind of roll shaft structure of card-less rotary cutter, and it is simple in structure, and fault rate is low, and long service life can be increased work efficiency greatly, and the product cost of being born.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of roll shaft structure of card-less rotary cutter, the roll shaft axis body carriage that comprises support, the first roll shaft axis body, the second roll shaft axis body, the 3rd roll shaft axis body, connection roll shaft axis body and support, it is characterized in that: described roll shaft axis body is the independent completion body, roll shaft axis body middle part is equipped with 1 roll shaft axis body bracket slot, roll shaft axis body as the independent completion body, prolonged the service life of roll shaft axis body, improved peeler work precision.

Further improvement as the technical program, be equipped with a plurality of grooves that are interspersed on the described first roll shaft axis body, the second roll shaft axis body, i.e. unnotched position on the corresponding second roll shaft axis body in reeded position on the first roll shaft axis body, interlaced groove structure, increase friction area, effectively avoid strengthening because of the beaming roller overstriking diameter of offal core.

As the further improvement of the technical program, described roll shaft axis body carriage one side is straight flange, is fixed on the support, and opposite side is the C connected in star, coincide with roll shaft axis body bracket slot.Roll shaft axis body carriage replaces original bearing and bearing block, can play the effect that prevents roll shaft axis body compressive deformation, and installation and maintenance are convenient.

Compared with prior art, the roll shaft structure of the utility model card-less rotary cutter changes segmentation roll shaft axis body into one, prolonged the service life of roll shaft axis body, improved peeler work precision, be equipped with 1 roll shaft axis body bracket slot on the roll shaft axis body, under the effect of roll shaft axis body carriage, it is stronger to bear the external force ability, make maintenance more convenient, be equipped with the groove that is interspersed on the first roll shaft axis body, the second roll shaft axis body, increase the rubbing surface in the timber process, reduced the waste of residue timber, reduced production cost.

The specific embodiment

See also Fig. 2 to shown in Figure 5, the utility model provides a kind of roll shaft structure of card-less rotary cutter, comprise support A, B, be fixed in the first roll shaft axis body 1, the second roll shaft axis body 2 at support A two ends, be fixed in the 3rd roll shaft axis body 3 at support B two ends, described roll shaft axis body is isometric, independent completion body, and roll shaft axis body middle part is equipped with 1 roll shaft axis body bracket slot 4.

It is straight flange that roll shaft axis body carriage 5 is fixed in support one side, opposite side is the C connected in star, C connected in star and roll shaft axis body bracket slot 4 match, and roll shaft axis body carriage 5 is shared the suffered external force of roll shaft axis body in the timber process, prevent the distortion at work of roll shaft axis body.

On the first roll shaft axis body 1, the second roll shaft axis body 2 a plurality of grooves 6 are arranged all, groove is interspersed, the position that does not namely have groove on the corresponding second roll shaft axis body 2 of the groove location on the first roll shaft axis body 1, the groove that is interspersed has increased the attrition surface of roll shaft axis body and timber in the timber process, has reduced the core diameter of residue timber.

Timber is adding 7 places of position in man-hour in Fig. 4, support A maintains static, the first roll shaft axis body 1 and the second roll shaft axis body 2 that are fixed on the support A can not move forward and backward, can only rotate, support B can move forward and backward, outer can also moving forward and backward with support B as required rotated in the 3rd roll shaft axis body 3 decapacitation that are fixed on the support B, when timber is placed, according to the timber thickness, mobile support B is until position suitable, in process, along with diminishing of timber core diameter, the 3rd roll shaft axis body 3 moves to the first roll shaft axis body 1 and the second roll shaft axis body, 2 directions gradually with support B, finishes processing request.

The roll shaft structure of the utility model card-less rotary cutter changes segmentation roll shaft axis body into one, prolonged the service life of roll shaft axis body, improved peeler work precision, be equipped with 1 roll shaft axis body bracket slot on the roll shaft axis body, under the effect of roll shaft axis body carriage, it is stronger to bear the external force ability, make maintenance more convenient, be equipped with the groove that is interspersed on the first roll shaft axis body, the second roll shaft axis body, increased the rubbing surface in the timber process, reduce the waste of residue timber, reduced production cost.

The above; it only is most preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; any those of ordinary skill in the art; do not breaking away under the technical solutions of the utility model scope situation; utilize the method content of above-mentioned announcement that technical solutions of the utility model are made many possible changes and modification, all belong to the scope of claims protection.
