sleeving a paper tube on the rotating sleeve 2, inserting one end of the paper tube to a step platform of the positioning sleeve 6 to complete the positioning of the end part of the paper tube, and leaving a gap between the paper tube and the rotating sleeve 2; then, the action of a power mechanism II is controlled to drive the conical sleeve 10 to move, the conical sleeve 10 props up the boss 15 in the moving process, the spring generates elasticity, the boss 15 drives the lever 13 to rotate along the hinged point, in the rotating process, the lever 13 drives the connecting rod 12 to move, so that the clamping knife 7 is clamped on the surface of the paper tube, and the clamping knife 7 is matched with the step platform to complete the fixed clamping of the paper tube; controlling the first air cylinder 28 to start, driving the arc-shaped bracket 29 to adjust to a proper height, and enabling the arc-shaped bracket 29 to support the other end of the rotating sleeve 2;
step two, starting the power mechanism I to drive the rotating shaft 9 to rotate, wherein the rotating shaft 9 rotates to drive the positioning sleeve 6 and the clamping knife 7 to rotate, and further the paper tube rotates;
and step three, controlling the cutting mechanism to act to complete the cutting of the paper tube.
The steps also comprise lateral jacking of the paper tube, and the specific method comprises the steps of adjusting the inclination angle of the bottom plate 53, fixing the paper tube through the bolt 54, controlling the second cylinder 5 to move, driving the wheel frame 51 to move, and enabling the wheels 52 to be in contact with the surface of the paper tube, so that when the cutting mechanism is subsequently used for cutting, as the wheels 52 are arranged on the opposite sides of the cutting mechanism, the wheels 52 can stably support the paper tube, and the paper tube is prevented from deflecting due to stress.
It can thus be seen that:
according to the invention, the rotating mechanism is improved, the outer diameter of the rotating sleeve 2 is designed to be smaller than the inner diameter of the paper tube, so that a gap is formed between the paper tube and the rotating sleeve 2, when the cutter 44 is used for cutting, the cutter 44 can be prevented from mistakenly cutting the rotating sleeve 2, a margin is left in the depth, the safety usability is high, and meanwhile, the paper tube can be conveniently installed and detached; because a gap is formed between the paper tube and the rotary sleeve 2, how to fix the paper tube is a big problem, the applicant specially designs a positioning mechanism, the positioning mechanism adopts the structural form of a conical sleeve 10 and a clamping knife 7, the clamping and the loosening of the clamping knife 7 can be realized by utilizing the reducing of the conical sleeve 10, and the operation is convenient and fast; the design of 6 terraces of position sleeve can guarantee on the one hand that the tip is spacing, simultaneously, realizes closely shoring to the paper tube, because the width of position sleeve 6 is narrower, makes things convenient for the butt joint and the dismantlement of paper tube, and the practicality is high.
But change and adopt the mode of relative rotation connection between cover 2 and the pivot 9, when the paper tube is rotatory promptly, change the cover and not rotate along with the pivot, can support rotating cover 2 through arc bracket 29, prevent that pivot 9 and rotating cover 2 from because the setting of encorbelmenting appear that the tip is flagging and then lead to unable coaxial problem, in case the disalignment will influence the cutting quality, this problem can perfectly be solved to arc bracket 29.
Considering that only a single-side fixing mode is adopted, the paper tube is possibly deflected due to acting force on the paper tube during cutting, an inclined opening is formed, and the cutting quality is not easy to guarantee, so that the applicant specially arranges a jacking mechanism, the jacking mechanism and the cutting mechanism are respectively arranged on two sides of the paper tube, the jacking mechanism provides jacking force for offsetting the acting force during cutting, the coaxiality of the paper tube and the rotating shaft 9 can be guaranteed, the use of the paper tube and the rotating shaft combined with the arc-shaped bracket 29 can realize the guarantee of the coaxiality in two transverse and vertical directions, and the cutting quality is improved; in addition, the wheels 52 can reduce friction force, prevent damage to the surface of the paper tube and ensure flatness.
While embodiments of the invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
