Abstract

The invention provides a slide fastener separating device of a slide fastener type flexible package bag packaging machine. The device is characterized in that a double-shaft cylinder of a rubbing clamp with an upper rubbing board and a rubbing board is fixed on a frame of the packaging machine, a compressing cylinder is fixed under the lower rubbing board close the opening position at the right end of the rubbing clamp, and a round bar type rubbing head is also fixed on the frame of the packaging machine. According to the invention, when a packaging bag embedded with a slide fastener is conveyed to the space between the rubbing clamp and the round bar type rubbing head, the double-shaft cylinder extends out and drives the rubbing clamp to move rightwards, the packaging bag is pushed toward the round bar type rubbing head, after the packaging bag is pushed and folded to half wrap the round bar type rubbing head, the compressing cylinder shrinks and clamps, and after the upper rubbing board and the lower rubbing board compress the packaging bag on the round bar type rubbing head moderately, the double-shaft cylinder shrinks and drives the rubbing clamp to move leftwards and retreat so as to leave the round bar type rubbing head, so that two surfaces of the packaging bag are separated, and the slide fastener of the packaging bag are also separated. By adopting a simple device, the mechanism of the slide fastener type flexible package bag packaging machine is greatly simplified, and the cost is lowered; and the device is practical and reliable.

Description

Zipper form soft packaging bag wrapping machine is opened chain stretching device

Technical field

The present invention has introduced a kind of zipper form soft packaging bag wrapping machine and has opened chain stretching device.

Background technology

At present, the food flexible packing bag has two major types, and one type is the zipper form (press insert type slide fastener) of resealable, and another kind of is non-zipper form.Zipper form soft packaging bag wrapping machine all is provided with out chain stretching device; Usually adopt the complicated combined zipper of opening of structure in the existing zipper form soft packaging bag wrapping machine; Its mechanism inhales through vacuum cup to open packing sack both sides, is clamped respectively by two flexible mechanical arms and inhales the both sides sack of opening, and clamping back two mechanical arms remake swing arm and rotate; Rip the slide fastener of packaging bag by force, accomplish and open the slide fastener operation in the automatic packaging process.This type of mechanism is because the motion link is many, and structure is complicated, and cost is generally all very high, and also can pull bad packaging bag once in a while, produces the nonconformity packing.

Summary of the invention

The technical matters that the present invention will solve is; In order to overcome the weak point of opening zipper in the existing zipper form soft packaging bag wrapping machine; Provide a kind of zipper form soft packaging bag wrapping machine to open chain stretching device; It is a constructional feature of utilizing packaging bag slide fastener itself, adopts the principle of rubbing bag with the hands to come the separately slide fastener of packaging bag.

Solution of the present invention is; Provide a kind of zipper form soft packaging bag wrapping machine to open chain stretching device; This device is that the twin shaft cylinder (1) with stranding folder (2) of last washboard (3) and following washboard (11) is fixed on the wrapping machine frame shown in accompanying drawing 1-3, and last washboard (3) all is equipped with rubber stranding head (7) with the right-hand member head of following washboard (11); There is clamping cylinder (13) to be fixed on down below the washboard (11) through a pad of lower inclined plane backing plate (12); The piston rod (6) of clamping cylinder (13) then passes washboard (3) and following washboard (11), and has roller (5) to be hinged on the top of piston rod (6), and roller (5) lower edge is pressed on the ramp backing plate (4) of washboard (3); Pressing from both sides the position that (2) right-hand member opens wide near rubbing with the hands, other has the pole type stranding head (10) of inlaying round rubber coating (9) also to be fixed on the wrapping machine frame.

Working process of the present invention is; Deliver between stranding folder (2) and the pole type stranding head (9) when the packaging bag that is embedded with slide fastener (14) (8), slide fastener this moment (14) and pole type are rubbed (10) axial line with the hands in vertical state, and twin shaft cylinder (1) stretches out to drive to rub with the hands and presss from both sides (2) right lateral; And push packaging bag (8) to the pole type and rub head (10) with the hands; Until last washboard (3) and play washboard (11) packaging bag (8) is pushed away to wrap in by half after the pole type rubs the round rubber coating (9) of head (10) with the hands and go up, twin shaft cylinder (1) stop motion, the piston rod (6) of clamping cylinder this moment (13) shrinks to drive to be gone up washboard (3) and presss from both sides with play washboard (11) receipts; Two rubber of last washboard (3) and play washboard (11) rub with the hands head (7) with packaging bag (8) appropriateness be pressed in round rubber coating (9) that the pole type rubs head (10) with the hands upward after; Piston rod (6) stops contraction, and twin shaft cylinder (1) shrinks to drive and rubs folder (2) left lateral with the hands then, retreats and leaves pole type stranding head (10); Because the friction force that rubber is rubbed with the hands between the two sides that the friction force between head (7) and round rubber coating (9) and packaging bag (8) two sides is superimposed together than packaging bag (8) is big; The one side that packaging bag (8) contacts with rubber stranding head (7) is attaching rubber stranding head (7) and is moving, and another side still is close on the round rubber coating (9), thereby draws back two faces of packaging bag (8); Even the slide fastener (14) above the packaging bag (8) also separates, that accomplishes packaging bag opens the slide fastener operation.

The invention has the beneficial effects as follows; Open the complicated combined zipper of opening of structure that chain stretching device replaces employing usually with simple zipper form soft packaging bag wrapping machine of the present invention; Greatly simplify the mechanism of zipper form soft packaging bag wrapping machine, reduced cost, and practical, reliable.

Description of drawings

Fig. 1 is that zipper form soft packaging bag wrapping machine of the present invention is opened the chain stretching device structural representation;

Fig. 2 is the upward view that zipper form soft packaging bag wrapping machine shown in Figure 1 is opened chain stretching device;

Fig. 3 is the left view of Fig. 2.

Among the figure: 1, twin shaft cylinder, 2, rub folder with the hands, 3, go up washboard, 4, the ramp backing plate, 5, roller; 6, piston rod, 7, rubber rubs head with the hands, 8, packaging bag, 9, round rubber coating, 10, the pole type rubs head with the hands; 11, following washboard, 12, the lower inclined plane backing plate, 13, clamping cylinder, 14, slide fastener.

The specific embodiment

A practical implementation of the present invention is for example shown in the accompanying drawing 1-3; Be that the twin shaft cylinder (1) with stranding folder (2) of last washboard (3) and following washboard (11) is fixed on the wrapping machine frame; This stranding folder (2) is opening and arranges towards the right side; The right-hand member head of last washboard (3) and play washboard (11) all is equipped with rubber rubs head (7) with the hands, clamping cylinder (13) is arranged below a pad of lower inclined plane backing plate (12) is fixed on down washboard (11), and the piston rod (6) of clamping cylinder (13) then passes washboard (3) and following washboard (11); And there is roller (5) to be hinged on the top of piston rod (6); Roller (5) lower edge is pressed on the ramp backing plate (4) of washboard (3), is pressing from both sides the position that (2) right-hand member opens wide near rubbing with the hands, and other has the pole type stranding head (10) of inlaying round rubber coating (9) also to be fixed on the wrapping machine frame.

It is reasonable in design that the zipper form soft packaging bag wrapping machine of the present invention that constitutes is thus opened chain stretching device, tries out through trial-production and be proved to be respond well, greatly simplified the mechanism of zipper form soft packaging bag wrapping machine, reduced cost, and practical, reliable.
