Description
Technical Field
The utility model belongs to the technical field of the peeler, concretely relates to swing feeds cam drive formula peeler.
Background
Among the prior art, rotary shaver generally all is provided with the slide rail of horizontal direction linear motion and supplies blade holder or two roller holders to do the spacing action of advancing and withdrawing the sword, and its drive mode is mostly the lead screw drive, and speed control adopts variable frequency speed governing to swing mode feed replaces current this kind of straight line feed mode, and mechanical structure can be simpler, and the reliability is also good, and is most common.
The rotary cutter has the problems that the rotary cutter can ensure the cutting back angle to be kept in a proper range, the research is carried out only by selecting a proper swing fulcrum position, particularly, the change of the back angle to be less than 0.3 degree is completely feasible aiming at the rotary cutter with the small diameter of less than 15 cm, the cutter can be fed and withdrawn by utilizing a 360-degree closed swing cam, the continuous work can be realized by conveniently adjusting the speed and automatically controlling the cutter to be not stopped and not to be reversed, and the quick-return characteristic is realized by reasonably distributing the cutter feeding and withdrawing angles of the cam, so that the rotary cutter is very important.
Based on the above principle, a full-automatic rotary cutting machine without clamp driven by a swing feed cam is developed, and the technical purpose to be realized by the utility model is taken as the necessary supplement of the existing rotary cutting machine.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem existing in the prior art and providing a swing feed cam drive type rotary cutter to overcome the defects of the prior art.
The utility model relates to a swing feed cam driving type rotary cutter, which comprises a frame; a double-roller seat is arranged on one side of the frame; a double roller rotatably connected with the double roller seat is arranged on the double roller seat; a cutter holder is arranged on the other side of the rack; the cutter holder is provided with a single-roller seat; a single roller is arranged on the single roller seat; a rotary cutter is arranged below the single roller;
the double-roller double; cam sliding plates are symmetrically and fixedly arranged on two sides of the cutter holder respectively; a cam which is attached to the cam sliding plate to slide is arranged below the cam sliding plate; the cam is in transmission connection with a transmission part arranged on the rack.
The utility model provides a continuous advancing and retracting of blade holder is realized in the continuous syntropy operation of cam, and the cam is power during the feed, leans on the blade holder dead weight slope during retracting.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a rotary cutter does not establish the linear motion track and adopts the swing to feed mechanical structure and simplify, and the control of veneer thickness degree of consistency has cam profile to confirm, and the cam constant speed is rotatory can the even veneer of rotary-cut, attaches to realize full-automatic rotary cutting with automatic feeding system single twin roll cam continuous rotation.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, a frame 2, a tool apron 3, a single-roller seat 4, a single roller 5, wood 6, a double roller 7, a double-roller seat 8, a cam 9, a cam shaft 10, a cam sliding plate 11 and a rotary cutter.
Detailed Description
Referring to fig. 1, the utility model relates to a swing feed cam driven rotary cutter, which comprises a frame 1; a double-roller seat 7 is arranged on one side of the frame 1; a double roller 6 which is rotatably connected with the double-roller seat 7 is arranged on the double-roller seat; a tool apron 2 is arranged on the other side of the rack 1; the tool apron 2 is provided with a single-roller seat 3; the single roller seat 3 is provided with a single roller 4; a rotary cutter 11 is arranged below the single roller 4;
one end of the cutter holder 2 is rotationally connected with the double-roller seat 7 through a rotating shaft; cam sliding plates 10 are symmetrically and fixedly arranged on two sides of the tool apron 2 respectively; a cam 8 which is attached to the cam sliding plate to slide is arranged below the cam sliding plate 10; the cam 8 is in transmission connection with a transmission part arranged on the frame 1.
The utility model provides a continuous advancing and retracting of blade holder is realized in the continuous syntropy operation of cam, and the cam is power during the feed, leans on the blade holder dead weight slope during retracting.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a rotary cutter does not establish the linear motion track and adopts the swing to feed mechanical structure and simplify, and the control of veneer thickness degree of consistency has cam profile to confirm, and the cam constant speed is rotatory can the even veneer of rotary-cut, attaches to realize full-automatic rotary cutting with automatic feeding system single twin roll cam continuous rotation.
The double-roller seat 7 is fixed on the frame 1, the camshaft 9 is supported, the rotary cutter 11 is installed on the cutter holder 2, the double rollers 6 are installed on the double-roller seat 7, the double-roller seat 7 is hinged to the cutter holder 2, the single roller seat 3 is provided with the single roller 4 which is installed on the cutter holder 2 together, the relative position of the single roller 4 and the rotary cutter 11 can be finely adjusted, and the two cams 8 are respectively arranged at the two sides of the cutter holder 2 and attached to the cam sliding plates 10 at the two ends of the camshaft 9 and the two sides of the cutter holder 2 in a symmetrical key-free connection mode. Fig. 1 shows the maximum opening position of the rotary cutting machine, the cam rotates counterclockwise to feed and cut the wood, when the rotary cutting at the top end of the curve is finished, the cam continues to rotate in the same direction and retracts by the dead weight of the tool holder 2 to the position shown in the figure to complete a working cycle, and the next wood is cut.
The shape of the cam 9 is strictly designed according to the rotary cutting process requirements and the mechanism parameters, the rotary cutting thickness of the cam 9 is linearly related to the rotary cutting linear speed, the rotary cutting thickness does not change along with the rotary cutting diameter, the control procedure is simplified, and the fault is low and the precision is high. The cam 9 is a 360-degree continuous closed cam, and the angle of the feed part is larger than that of the withdrawal part, so that the cutting machine has a quick return characteristic, and the working efficiency of the rotary cutter is improved.
