Description
Technical field
The utility model belongs to packing mechanical equipment field, relates to a kind of piston type controllable switch device.
Background technology
At present, the corrugated paper molding structure using in Corrugating Machine generally includes watt roller and lower watt of roller, in order to allow corrugated paper be adsorbed on lower watt of roller, guarantee the smooth gluing of corrugated paper, the uniform pore of offering of meeting on the roll body of common lower watt of roller, the two ends of lower watt of roller or surface connect air extractor, by taking above-mentioned technological means, Corrugating Machine is when work, and corrugated paper can be adsorbed on watt roller while passing through lower watt of roller, guarantees watt paper and upper glue roller run-in synchronism.Find that in practice the ubiquitous problem of such scheme is: when the width of the corrugated paper that sometimes will produce is less than the width of machine (lower watt of roller), can cause the place not covered by watt paper on watt roller that the phenomenon of pore gas leakage can occur, cause energy loss, in addition, the centre position that fits in watt roller due to watt paper is located, and air extractor is to bleed from roll body two ends on watt roller, this has just caused the air-leak section at both ends on roll body, leak gas larger, and to centre, successively decrease gradually, and then have influence on watt absorption affinity of roller middle part surface to watt paper.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of piston type controllable switch device simple in structure, ingenious, rational is provided, and this device can regulate according to the corrugated paper of required production the quantity of air vent on Corrugator roller.
The technical scheme providing according to the utility model: a kind of piston type controllable switch device, be characterised in that: comprise the Corrugator roller that is circular, described Corrugator roller outer shroud length surface direction is laid with the vacuum annular groove that several are radially arranged, in Corrugator roller, place, ring centre position is provided with bleeding point, and the endoporus of Corrugator roller is connected in bleeding point lower end; Along the circumferential direction uniformly in annular groove between outer shroud and interior ring offer a plurality of axially extending bores, described in each, through hole and vacuum annular groove and bleeding point are interconnected, in the inner both sides of through hole, be respectively equipped with left piston, right piston, screw mandrel runs through described left piston, right piston vertically, screw mandrel arranged on left and right sides surface forms respectively the first threaded portion, the second threaded portion, left piston is connected on described the first threaded portion, right piston is connected on described the second threaded portion, and described the first threaded portion thread surface is contrary with the second threaded portion thread surface rotation direction.
As further improvement of the utility model, described bleeding point has one at least.
Compared with prior art, advantage is the utility model: the utility model product structure is simple, design, reasonable, and the width of the corrugated paper that can produce as required effectively regulates the quantity of the passage on Corrugator roller; When the width of the corrugated paper of processing is less than the width of Corrugator roller, regulate both sides piston to move to centre, because this product hermeticity can be good, must cause negative pressure in Corrugator roller to raise, reach the effect of sizing, and can be effectively energy-conservation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram of left piston or right piston.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, comprise left piston 1, vacuum annular groove 2, right piston 3, screw mandrel 4, the first threaded portion 4-1, the second threaded portion 4-2, Corrugator roller 5, bleeding point 6, through hole 7, endoporus 8 etc.
As shown in Figure 1 and Figure 2, a kind of piston type controllable switch device of the utility model, comprise the Corrugator roller 5 that is circular, described Corrugator roller 5 outer shroud length surface directions are laid with the vacuum annular groove 2 that several are radially arranged, place, the interior ring of Corrugator roller 5 centre position is provided with bleeding point 6, and the endoporus 8 of Corrugator roller is connected in bleeding point 6 lower ends, along the circumferential direction uniformly in annular groove between outer shroud and interior ring offer a plurality of axially extending bores 7, described in each, through hole 7 is interconnected with vacuum annular groove 2 and bleeding point 6, in the inner both sides of through hole 7, be respectively equipped with left piston 1, right piston 3, screw mandrel 4 runs through described left piston 1 vertically, right piston 3, screw mandrel 4 left sides, right both side surface forms respectively the first threaded portion 4-1, the second threaded portion 4-2, left piston 1 is connected on described the first threaded portion 4-1, right piston 3 is connected on described the second threaded portion 4-2, and described the first threaded portion 4-1 thread surface is contrary with the second threaded portion 4-2 thread surface rotation direction.
Described bleeding point 6 has one at least, and when the quantity of bleeding point is one, this bleeding point is placed in the interior ring of Corrugator roller 5 centre position.
Operation principle of the present utility model is as follows: when the width of the corrugated paper of needs processing is less than the length of Corrugator roller, rotary screw rod 4, by screw mandrel 4, drive left piston 1, right piston 3 provided thereon to draw close to the centre of Corrugator roller 5, to reduce the quantity of the vacuum annular groove 2 of ventilation on Corrugator roller 5, reach energy-conservation object; Above-mentioned purpose be achieved be mainly due to: 4 liang of end surfaces of screw mandrel are provided with the first threaded portion 4-1 and the second threaded portion 4-2 that rotation direction is contrary, left piston 1 is equipped with on the first threaded portion 4-1, right piston 3 is equipped with on the second threaded portion 4-2, guarantee when screw mandrel 4 rotates, left piston 1 was drawn close in the middle of Corrugator roller 5 with right piston 3 or while, or to Corrugator roller 5 both sides, moved simultaneously; While rotating for fear of screw mandrel 4 simultaneously, left piston 1 and right piston 3 are followed screw mandrel 4 and are synchronizeed rotation, structure to left piston 1, right piston 3 has been carried out particular design,, on left piston 1, right piston 3 surfaces, be equipped with engaging lug, engaging lug is placed in the groove that Corrugator roller 5 offers vertically, guarantees that left piston 1, right piston 3 can only move vertically, and can not rotate.
The utility model product structure is simple, design, reasonable, and the width of the corrugated paper that can produce as required effectively regulates the quantity of the passage on Corrugator roller; When the width of the corrugated paper of processing is less than the width of Corrugator roller, regulate both sides piston to move to centre, because this product hermeticity can be good, must cause negative pressure in Corrugator roller to raise, reach the effect of sizing, and can be effectively energy-conservation.
