Abstract
A kind of adjustable hydraulic damping device for transverse cutting machine back feed paper, it is made up of cylinder body (1), piston rod (2), limit removing from mould air restrictor (3,4), oil pipe (5), spring (6), cylinder cap (7), top board (8); It also has nut (9), and nut (9) is contained on the piston rod (2) by screw thread, and spring one end is against in the seat hole of cylinder cap (7), and the other end is against on the nut (9).Top board (8) becomes revolute pair by straight pin with piston rod (2) end connection.Advantage is: the present invention compared with prior art, compact conformation, easy to adjust, be fit to the action of low speed high frequency, cost is low, cost of production is few, installs, maintenance is convenient.
Description
Technical field
The present invention relates to corrugated board production machinery auxiliary field, relate in particular to a kind of adjustable hydraulic damping device for transverse cutting machine back feed paper.
Background technology
Transverse cutting unit is an extremely important unit on the corrugated paper board production line.After the cardboard crosscut, require the cardboard of the discontinuous operation of different length is steadily exported, again not to not cut paper plate operation formation disturbance, otherwise, will influence the cut paper precision, this just requires defeated letterweight power is carried out active balance and buffering control.The balance of transverse cutting machine back feed paper and shock absorber have following several mode in the market: 1, the clump weight balance adds the extension spring buffering.This structure takes up room greatly, and extension spring causes spring easily, defeated paper stationarity of influence and cut paper precision.2, the clump weight balance adds the cylinder energy disperser.Because cylinder is suitable for the quick operated buffering with energy disperser, rigidity is soft, so necessary with the energy disperser competence exertion effect of one group of cylinder, so the cost height, structure is not compact yet.
Summary of the invention
Purpose of the present invention is exactly at the balance and the above-mentioned deficiency of shock absorber of transverse cutting machine back feed paper in the market, and provide a kind of compact conformation, can directly adjust the auxiliary device of defeated letterweight power and buffering effect, promptly a kind of adjustable hydraulic damping device for transverse cutting machine back feed paper.
The present invention is made up of cylinder body 1, piston rod 2, top board 8, limit removing from mould air restrictor 3,4, oil pipe 5, spring 6, cylinder cap 7; Cylinder cap 7 is buckled on the cylinder mouth of cylinder body 1, in cylinder body 1, be separated with fluid chamber 1-1 and following fluid chamber 1-2 by piston rod 2 and cylinder cap 7, last fluid chamber 1-1 and following fluid chamber 1-2 are respectively equipped with hydraulic fluid port, oil pipe 5 two ends communicate with the hydraulic fluid port of last fluid chamber 1-1 and the hydraulic fluid port of following fluid chamber 1-2 by limit removing from mould air restrictor 3 and limit removing from mould air restrictor 4 respectively, piston rod 2 one ends link to each other with top board 8, spring 6 is placed in piston rod 2 external parts, one end is against in the seat hole of cylinder cap 7, and the other end is against on the top board 8.It also has nut 9, has outside thread at piston rod 2 one ends, and nut 9 is contained on the piston rod 2 by screw thread, and spring one end is against in the seat hole of cylinder cap 7, and the other end is against on the nut 9.Top board 8 can become revolute pair with piston rod 2 end connections by straight pin.
Advantage of the present invention is: the present invention compared with prior art, compact conformation, easy to adjust, be fit to the action of low speed high frequency, cost is low, cost of production is few, installs, maintenance is convenient.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention; Accompanying drawing 2 is scheme of installation of the present invention.
Specific embodiments
Cylinder cap is buckled on the cylinder mouth of cylinder body, piston rod is "T"-shaped, in cylinder body, be separated with fluid chamber and following fluid chamber by piston rod and cylinder cap, last fluid chamber and following fluid chamber are respectively equipped with hydraulic fluid port, the oil pipe two ends (are the flow regulating valve of limitting out check valve in parallel by limit removing from mould air restrictor respectively, regulate its throttling bore respectively, the lower oil cavitie string speed oil of both direction from top to bottom or from the bottom up on just changing) communicate with the hydraulic fluid port of last fluid chamber and the hydraulic fluid port of following fluid chamber, top board can be coupled to revolute pair by straight pin and piston rod end.Spring is placed in the piston rod external part, and an end is against in the seat hole of gland, and the other end is against on the top board.Have outside thread at piston rod one end, nut is contained on the piston rod by screw thread, and spring one end is against in the seat hole of gland, and the other end is against on the nut, and setting nut changes the elastic force of spring can adjust defeated paper press force, sees Fig. 1.
Using method: as shown in Figure 2, the cardboard 11 of operation through a pair of crosscut rotor 12, is cut into the cardboard 13 of control preseting length continuously, by the two roller belt conveyors 14 in front and back, exports next procedure under the pressure holding of last feed rollers 15.Last feed rollers 15 is contained in 16 of fixing hinged connecting levers, can fluctuate.When its deadweight or the dynamic load that float to produce cause press force excessive, will damage paper and the stupefied type of corrugation of carrying cardboard; In addition, when preseting length equals or be slightly larger than crosscut rotor 12 to the horizontal throw of last feed rollers 15, in the time of the damage paper, will produce disturbance with detecting, influence the crosscut precision the operation of cardboard.For avoiding these problems, in the coaxial mounting hole of connecting lever 16 and last feed rollers 15, load onto this adjustable hydraulic damping device for transverse cutting machine back feed paper 17.
Mode of operation: limit removing from mould air restrictor is regulated its throttling bore, just can change the upper and lower oil pocket string speed oil of both direction from top to bottom or from the bottom up, makes connecting lever 16 and last feed rollers 15 fluctuate surge time of both direction adjusted.Top board is coupled to revolute pair by straight pin and piston rod end.When top board fixedly the time, piston rod only bears axial load, is beneficial to sealing, increases the service life; Setting nut changes the elastic force of spring can adjust defeated paper press force; When defeated paper press force transfers to the minimum press force of next procedure requirement, and downward surge time transfers to greater than cardboard and at interval during elapsed time, will can not damage cardboard again and influence the crosscut precision.
