Abstract

The utility model discloses an automatic-centralized closing-cutting device capable of re-centralizing a side plate of a supporting tray entering a closing-cutting line to enable a closing blade not to cut the side plate of the supporting tray by error during cutting of the closing blade. The utility model comprises a machine frame, an upper bracket fixed on the upper part of the machine frame, an upper piston cylinder fixed on the upper bracket, a closing blade fixedly connected with an upper piston rod in the upper piston cylinder, a lower bracket fixed on the lower part of the machine frame, a lower piston cylinder fixed on the lower bracket, and a silica gel fixing seat fixed on a lower piston rod in the lower piston cylinder. Because of the lower piston cylinder adopted in the device, the upper piston cylinder and the lower piston cylinder can work together to fundamentally solve the problem of miscut of the closing blade and improve production efficiency. The device can be widely used in the field of automatic flow process of encasing machinery.

Description

A kind of self-righting sealing-cutting device

Technical field

The utility model relates to a kind of wrapping machine, refers more particularly to the sealing-cutting device in a kind of wrapping machine.

Background technology

Generally, all be provided with sealing-cutting device in the wrapping machine, mainly comprise: frame, the top of frame is set with upper bracket, be set with the upper piston cylinder on the upper bracket, the envelope cutter is captiveed joint with the upper piston rod in the upper piston cylinder, and the bottom of frame is set with the silica stationary seat, and the bench board of silica stationary seat and frame both sides maintains an equal level.During work, after bottom tray that push pedal will need to seal film is pushed into sealing-cutting device along workplatform, push pedal is withdrawed from immediately, the envelope cutter that is fixed on then on the upper piston rod constantly moves down under the effect of upper piston cylinder, until joining, realize the film that is coated on the bottom tray is sealed the purpose of cutting on the silica stationary seat with the silica stationary seat.In real work, be provided with bending line between base plate on the bottom tray and the side plate, after bottom tray is pushed into the envelope tangent line, side plate on the bottom tray becomes the bending state under the pushing of push pedal, but after push pedal is return, because bottom tray is generally all thinner, the side plate of bottom tray can not keep the bending state long period, can be toppled over to straight direction again by the side plate of bending, cause side plate to enter into before envelope is cut in the stroke range of envelope cutter, seal and cut this moment, and the envelope cutter is not to cut on film, but cut on side plate, cause envelope to cut failure.

The utility model content

Thereby technical problem to be solved in the utility model provides the side plate of bottom tray that a kind of energy will enter the envelope tangent line and sets upright again and make the envelope cutter can not cut the sealing-cutting device on the bottom tray side plate in the incision process by mistake.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of self-righting sealing-cutting device, comprise: frame, top in frame is set with upper bracket, be set with the upper piston cylinder on upper bracket, the envelope cutter is captiveed joint with the upper piston rod in the upper piston cylinder, is set with lower bracket in the bottom of described frame, on lower bracket, be set with the lower piston cylinder, be set with the silica stationary seat on the lower piston rod in the lower piston cylinder.

The sense of motion that is parallel to upper and lower piston rod between the above-mentioned upper and lower support is set with two pilot bars, two pilot bars active passing from envelope cutter and silica stationary seat.

The beneficial effects of the utility model are: owing to set up a lower piston cylinder in the bottom of frame, in the descending process of envelope cutter, the silica stationary seat that is fixed on the lower piston rod also begins up under the effect of lower piston cylinder, one side side of up silica stationary seat just in time buttresses the side plate of bottom tray, make it keep the bending state, fundamentally solve the problem that envelope cutter mistake is cut, improved production efficiency.

Description of drawings

Fig. 1 is a main TV structure scheme drawing of the present utility model;

Fig. 2 is the view of A-A when the envelope of being looked is cut the beginning among Fig. 1;

Fig. 3 is that the envelope cutter seals view when cutting among Fig. 2.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing, but the utility model should not only limit to this embodiment.

As shown in Figure 1, a kind of self-righting sealing-cutting device described in the utility model comprises: frame 1 is set with upper bracket 11 on the top of frame 1, be set with upper piston cylinder 2 on upper bracket 11, envelope cutter 3 is captiveed joint with the upper piston rod 21 in the upper piston cylinder 2; Be set with lower bracket 12 in the bottom of frame 1, on lower bracket 12, be set with lower piston cylinder 6, and upper and

lower piston rod

21,61 is parallel to each other, be set with silica stationary seat 5 on the lower piston rod 61 in lower piston cylinder 6.When actual fabrication, on the sense of motion that is parallel to upper and

lower piston rod

21,61, be set with two pilot bars 4 between the above-mentioned upper and

lower support

11,12, two pilot bars 4 active passing from envelope cutter 3 and silica stationary seat 5, that is: envelope cutter 3 and silica stationary seat 5 all can slide along pilot bar 4 easy on and off; Silica stationary seat 5 maintains an equal level with the bench board 20 of frame 1 both sides.

The principle of work of sealing-cutting device described in the utility model is: as shown in Figure 2, the bottom tray 7 that needs is coated film 8 when push pedal is when workplatform 20 pushes sealing-cutting device and be pushed into the envelope tangent line, side side plate 71 on the bottom tray 7 becomes the bending state under the pushing of push pedal, but after push pedal is return, because bottom tray 7 is generally all thinner, one side side plate 71 of bottom tray 7 can not keep the bending state long period, just can the straight direction before bending be toppled over again by the side plate 71 of bending---as shown in Figure 2; At this moment,, depend upper piston cylinder 2 alone and cut, envelope cutter 3 mistakes are cut on the side plate 71 of the bottom tray 7 of toppling over, cause envelope to cut failure by upper piston rod 21 drive envelope cuttves 3 descending envelopes if silica stationary seat 5 is motionless; And the utility model is by being provided with the lower piston cylinder, drive the envelope that is arranged on the upper piston rod 21 at upper piston cylinder 2 and cut 3 along pilot bar 4 when descending, lower piston cylinder 6 is also started working, the silica stationary seat 5 that drive is arranged on the lower piston rod 61 moves up along pilot bar 4, and the side plate 71 of toppling over is set upright.Concrete working process is: upper and

lower piston rod

21,61 drives envelope cutter 3 respectively and silica stationary seat 5 is done relative motion, also drawn close gradually along pilot bar 4, up silica stationary seat 5 positive good utilisation one side sides are set upright a side side plate 71 of toppling on the bottom tray 7 gradually, finally join on the top of side plate 71 and descending

envelope cutter

3,3 pairs of bags of realization envelope cutter are carried out and are sealed the purpose of cutting at the film on the bottom tray 78 on silica stationary seat 5---as shown in Figure 3; Envelope cuts complete, upper and

lower piston cylinder

2,6 beginning reverse operations, and upper and

lower piston rod

21 and 61 drives envelope cutter 3 and silica stationary seat 5 is got back to initial position---referring to shown in Figure 2, prepare for seal to cut next time.
