Abstract
The invention discloses a transverse seal cutting mechanism of a vertical packaging machine which includes a transverse seal bottom plate (33), a front sealing cutter (51), a back sealing cutter (52) and a cutter (53). A cam (27) is arranged on the back of the transverse seal bottom plate. The back sealing cutter is connected with an installation base (17) of a back sealing cutter. The installation base of the back sealing cutter is connected with the groove of the cam through a back pushing plate (31). A transmission shaft (28) which passes through the transverse seal bottom plate is arranged on the center of the cam. The transmission shaft is connected with a motor (36) which is equipped with a reduction gearbox. A guiding shaft (7) is installed on the two sides of the cam and on the transverse seal bottom plate. A front seat (11) and a connecting plate (21) are respectively arranged between the front end and the back end of the guiding shaft. The front seat is connected with the front sealing cutter. The connecting plate is connected with the groove of the cam through a front pushing plate (24). The invention can realize the low temperature thermal sealing and the constant temperature timing sealing on plastic films. The expansion ratio and the firmness of the sealing are improved. The thermal sealing cutter is driven by bidirectional center force of the cam and the two guiding shaft, which improves the thermal sealing quality and lowers the working noises.
Description
One, technical field
The present invention relates to a kind of packing mechanical equipment, specifically relate to a kind of traverse closing-cutting mechanism of upright packing machine.
Two, background technology
At present, the traverse closing-cutting mechanism of vertical material packing machine is that the plastic sheeting after the material filling is carried out transversal heat seal, cuts off to make required packaging bag (serving as three banding bags of back of the body envelope formula), the action of its hot knife, cutting knife is controlled by cylinder separately, and hot knife then earlier drives crank again, cranks arm and realize by cylinder the heat-sealing of plastic sheeting.Because the air pressure that cylinder produces, the size of air-flow are difficult to accurate control, the power that crank, the motion of cranking arm produce is unidirectional force again, temperature height during heat-sealing, sealing can be wrinkling, thereby the heat-sealing effect of plastic sheeting is brought negative effect, and the noise that the action of two cylinders produces is higher.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and provide a kind of low noise, plastic sheeting can realized to seal the traverse closing-cutting mechanism of upright packing machine that can be not wrinkling.
Purpose of the present invention realizes by following technical solution: a kind of traverse closing-cutting mechanism of upright packing machine, comprise horizontal sealing base plate, preceding envelope cutter, back envelope cutter, cutting knife, cutting knife links to each other with the cutting knife cylinder, on the rear portion of described horizontal sealing base plate, cam is housed, back envelope cutter links to each other with back envelope cutter mount pad, and back envelope cutter mount pad joins by the groove of back push pedal and cam; In described cam center, pass the horizontal sealing base plate and transmission shaft be housed, transmission shaft links to each other with the motor of band drop-gear box; On described cam both sides, horizontal sealing base plate the axis of guide is housed, front stall, connecting panel are housed respectively between the front end of the axis of guide, the rear end, front stall links to each other with preceding envelope cutter, and connecting panel joins by the groove of preceding push pedal and cam.
After adopting structure of the present invention, preceding push pedal, back push pedal are travelled forward or motion backward by electric machine control cam rotation, thus envelope cutter and back envelope cutter closed or separate to come plastic sheeting is sealed or enters before making.Thereby can realize regularly involution of low-temperature heat-sealing, constant temperature to plastic sheeting, improve magnification ratio, the firmness of plastic sheeting involution; Drive by cam, two axis of guides is two-way central force to hot knife, has promoted the quality of heat-sealing, and has reduced work noise.
Four, description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of the traverse closing-cutting mechanism of upright packing machine of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the back view of Fig. 1.
Five, the specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3 as can be known, the traverse closing-cutting mechanism of upright packing machine of the present invention, comprise horizontal sealing base plate 33, preceding envelope cutter 51, back envelope cutter 52, cutting knife 53, cutting knife 53 (by cutting knife mounting blocks 54) (only is one with cutting knife cylinder 55, reduced noise) link to each other, cam 27 is housed on the rear portion of described horizontal sealing base plate 33, and envelope cutter 52 in back links to each other with back envelope cutter mount pad 17, and back envelope cutter mount pad 17 grooves by back push pedal 31 and cam 27 join; At described cam 27 centers, pass horizontal sealing base plate 33 and transmission shaft 28 be housed, transmission shaft 28 links to each other with the motor 36 of band drop-gear box; On described cam 27 both sides, horizontal sealing base plate 33, the axis of guide 7 is housed, front stall 11, connecting panel 21 (using nut 8,18 to fix) are housed respectively between the front end of the axis of guide 7, the rear end, front stall 11 (by screw 4) links to each other with preceding envelope cutter 51, and connecting panel 21 joins by the groove of preceding push pedal 24 with cam 27.
Wherein: the groove oval in shape of cam 27, preceding push pedal 24 and back push pedal 31 are connected in two of this groove respectively; On horizontal sealing base plate 33, the axis of guide also is equipped with the box unit 12 of several linear bearings for 7 times; Cutting knife cylinder 55 can be contained on the back envelope cutter mount pad 17; The motor 36 of band drop-gear box is contained in the horizontal sealing base plate 33 times by motor mounting plate 56, and the motor 36 of described band drop-gear box can be servomotor (in order to control the rotating speed of transmission shaft more accurately), and it links to each other with drop-gear box 46 by coupler 39, as shown in Figure 2; The front end of transmission shaft 28 is equipped with flat key 29, and is contained in the center of cam 27 with circlip 30; For back envelope cutter is moved more stably, described back envelope cutter mount pad 17 all is enclosed within on two axis of guides 7, as shown in Figure 1.
Principle of work of the present invention is: electric motor starting and drive drop-gear box, transmission shaft work, thus drive the cam rotation.When plastic sheeting need seal, back push pedal, preceding push pedal move to A, the B position of cam groove shown in Figure 1, the moving back of pusher strip envelope cutter mount pad travels forward back envelope cutter, before push pedal drive connecting panel, the axis of guide, front stall and make before the envelope cutter move backward, preceding envelope cutter is closed and plastic sheeting is sealed with back envelope cutter.At this moment, preceding envelope cutter is determined by rotating speed of motor fully with the speed of back envelope cutter motion, can realize regularly involution of low-temperature heat-sealing, constant temperature to plastic sheeting, improves magnification ratio, the firmness of plastic sheeting involution, and it is unlikely wrinkling that its heat-sealing is sealed.Then, the cutting knife cylinder is also along with back envelope cutter mount pad and promote cutting knife and travel forward the plastic sheeting that has sealed realized cutting off and make packaging bag.When plastic sheeting need enter, back push pedal, preceding push pedal move to C, the D position (dotted line is represented) of cam groove shown in Figure 1, the moving back of pusher strip envelope cutter mount pad moves back envelope cutter backward, before push pedal drive connecting panel, the axis of guide, front stall and make before the envelope cutter travel forward, preceding envelope cutter separates with back envelope cutter and plastic sheeting is entered.
