A kind of vacuum sealer of automatic pinch-off seal
Technical field
The utility model relates to the vacuum sealer of a kind of vacuum sealer, particularly a kind of automatic pinch-off seal.
Background technology
At present, the cover of vacuum sealer product be manual pressing structure mostly, when vacuum packing product, need manually will seal cover compresses downwards and with the fuselage fastening after, carry out vacuum suction and heat sealing again.This structure operation is got up inadequately convenient, because cover is the machinery fastening with fuselage, also has the gap between the buckle, and annular seal space is fitted tightly, and causes easily to seal bad and leak gas.
Summary of the invention
In order to overcome the deficiency of existing vacuum sealer, the utility model provides a kind of vacuum sealer of automatic pinch-off seal.This capper need not manually to fasten cover, and only need needs vacuum-packed packaging bag be positioned over the capper workplatform, press switch, cover automatically downwards fastening and fit tightly with fuselage after, capper carries out vacuum suction and heat sealing again to be operated.
For solving the problems of the technologies described above, the utility model is realized as follows: a kind of vacuum sealer of automatic pinch-off seal comprises fuselage, cover, vacuum suction device, heat sealing plate, derby, electromagnet and automatic pressing device.
Said automatic pressing device comprises a cylinder, an air cylinder tie rod, a briquetting, a retracing spring, a connection transmission shaft; Be provided with the cylinder spring in the said cylinder; One end of said air cylinder tie rod places cylinder interior, and said retracing spring places under the briquetting, and the retracing spring tail end is stuck on the fuselage plane; The two ends of said connection transmission shaft connect the cover of capper; Said briquetting places on the said connection transmission shaft, and when said inblock cylinder band of gas dynamic air cylinder pull bar was moved downward, the other end of air cylinder tie rod contacted with briquetting.
Said cover is provided with derby, on this capper fuselage and the corresponding position of derby, is provided with electromagnet, and said derby is arranged on the cover two ends.
The good effect of the utility model is: the use of the utility model, and capper packaged products annular seal space is fitted tightly, reach good sealing property, easy to operate.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
A kind of vacuum sealer of automatic pinch-off seal comprises: fuselage (101), cover (102), vacuum suction device (not shown), heat sealing plate (not shown), derby (205), electromagnet (206) and automatic pressing device.
Said automatic pressing device comprises a cylinder (201), an air cylinder tie rod (202), a briquetting (203), a retracing spring (210), a connection transmission shaft (204); Be provided with cylinder spring (209) in the said cylinder (201); One end of said air cylinder tie rod (202) places cylinder (201) inside; Said retracing spring (210) places under the briquetting (203); Retracing spring (210) tail end is stuck on fuselage (101) plane, and the two ends of said connection transmission shaft (204) connect the cover (102) of capper, and said briquetting (203) places on the said connection transmission shaft (204); Make said cylinder (201) exhaust drive air cylinder tie rod (202) when moving downward, the other end of air cylinder tie rod (202) contacts with briquetting (203).
Said cover (102) is provided with derby (205), on this capper fuselage (101) and the corresponding position of derby (205), is provided with electromagnet (206), and said derby (205) is arranged on cover (102) two ends.
As shown in Figure 2; Behind this capper of starting, cylinder (201) carries out exhaust drive air cylinder tie rod (202) and moves downward, and air cylinder tie rod (202) is rotated down it through being arranged at the briquetting (203) that connects on the transmission shaft (204); Thereby drive and is connected the downward fastening of transmission shaft (204) bonded assembly cover (102); Cover (102) and fuselage (101) are fitted tightly, be the tight ness rating of reinforcement cover (102) with the fastening of fuselage (101), cover (102) two ends are provided with derby (205); Be provided with electromagnet (206) with the fuselage (101) of derby (205) correspondence position; After cover (102) and fuselage (101) fastened, electromagnet (206) and derby (205) adhesive had each other increased the tight ness rating that cover (102) and fuselage (101) are fitted.Cover (102) carries out vacuum suction and heat sealing operation after fitting tightly with fuselage (101) again.When sealing operation is accomplished; Electromagnet (206) outage separates with derby (205); Cylinder (201) loses heart simultaneously; Cylinder spring (209) in the cylinder (201) upwards pushes away air cylinder tie rod (202), and briquetting (203) also and then rotates up under the effect of retracing spring (210) after losing pressure, thereby drives and be connected transmission shaft (204) bonded assembly cover (102) and open.
