Detailed Description

The first embodiment; as shown in fig. 1-2, a vacuum packaging machine cover comprises a cover body 100, wherein a hollow part 110 for installing a transparent observation window 200 is arranged at a position, with small stress, of the cover body 100, the transparent observation window 200 is further included, the transparent observation window 200 is fixedly assembled at the hollow part 110 and is in sealing fit with the cover body 100, the transparent observation window 200 is arranged to enable the packaging machine to see an internal working process during operation, the internal condition can be seen during maintenance, and the periphery of the cover is mainly made of metal or other firm materials, so that the cover is not easy to deform, crack or break; the position that cover body and vacuum chamber are connected also is metal or other firm material, and non-deformable is difficult for bursting, the breakage, and the position that the vacuum chamber is connected is all at the edge of certain one side of lid, and when the machine worked, incessantly repeated opening and closed in-process, this edge junction is long-term atress, is the place that the atress is the biggest moreover, and its top atress is less relatively, so set up transparent viewing window here, can not produce any negative effect to the use of cover.

The transparent observation window 200 is fixedly assembled at the hollow part 110 of the cover body 100 through bolts, and because the vacuum packaging machine evacuates air inside when in use, negative pressure is generated, so that the structure is fixed through the bolts more firmly.

The cover body 100 is provided with a recessed step 120 at the edge of the hollow 110, the step 120 is provided with a step surface 121, the step surface 121 is provided with a plurality of bolt connecting seats 122, the edge of the transparent observation window 200 is provided with a plurality of holes or notches 210 for bolts to pass through, the transparent observation window further comprises a pressing plate 300, the pressing plate 300 is provided with a plurality of through holes 310 for bolts to pass through, the bolts pass through the through holes 310 of the pressing plate 300 and the holes or notches 210 of the transparent observation window 200 and are in threaded connection and fixation with the bolt connecting seats 122, the design that the transparent observation window 200 is provided with the notches 210 at the edge is adopted in the embodiment, when the glass is processed, the glass and the number of the bolts are set according to specific requirements, the eight bolts are regularly arranged and installed in the embodiment, the installation effect is stable, the transparent observation window 200 is pressed into the recessed step 120 through, the transparent observation window 200 is inserted into the pressing plate 300, and the pressing plate is screwed and fastened with the screw connection seat 122 through a screw.

Transparent observation window 200 laminating cover body 100's one side border department is equipped with the recess (not shown) that is used for imbedding sealing washer 220, still includes sealing washer 220, in the sealing washer 220 embedding recess, the recess outside is arranged in to hole or incision 210 at transparent observation window 200 border, realizes the sealed cooperation between transparent observation window 200 and the cover body 100 through sealing washer 220, because sealing washer 220 sets up at the bolt inner circle, so incision 210 or the hole on the transparent observation window 200 can not influence its leakproofness.

The steps 120 are formed by bending the plate located at the hollow part 110 of the cover body 100, and the edges of the adjacent steps 120 are sealed into a whole by welding, so that the sealing performance and the structural stability of the cover body are ensured.

The bolt connecting seat 122 is fixed on the step surface 121 through welding, so that the assembling stability of the transparent observation window 200 is ensured.

Transparent observation window 200 is made for the glass material, for current transparent glass cover, its thickness specifically sets for according to the cover size, and it wholly adopts the glass material to make, and at vacuum packaging machine during operation, form the negative pressure in the cover, and the cover that traditional glass material made bursts easily under stronger negative pressure, and is very dangerous, and the whole fuselage of this product adopts the metal material, and under the negative pressure condition, the position that influences the minimum sets up transparent observation length, can not influence the whole steadiness of fuselage, can observe the inside condition simultaneously.

Transparent observation window 200 shape is circular, ellipse, rectangle or polygon, and cover body 100's fretwork 110 shape and transparent observation window 200 shape phase-match, and transparent observation window 200 shape does not do too much and gives unnecessary details, and what adopt in this embodiment is square observation window, does benefit to production and processing.

The first embodiment; as shown in fig. 3, the present embodiment is applied to a single-box vacuum packaging machine, and the assembly thereof is consistent with the conventional assembly structure, which will not be described in detail.

Example two; as shown in fig. 4, the present embodiment is applied to a double-box vacuum packaging machine, and the position of the cover is switched by swinging of two rocker arms, which is also a common structure of the existing vacuum packaging machine and will not be described in detail.

Except that the transparent observation window 200 is additionally provided with the sealing ring 220 for sealing, the sealing mode of other parts of the product is consistent with the structure of the traditional packaging machine, and redundant description is not repeated.

The connection between the lid body 100 and the vacuum chamber is made by a portion of metal or another sturdy material surrounding the lid body 100.

The utility model provides a vacuum packaging machine cover, the product is convenient for observing the processing condition in the vacuum packaging machine by arranging a transparent observation window on the cover, the operation is convenient, the structure is simple, the sealing performance is good, the normal operation of the vacuum packaging machine can be ensured, and the vacuum packaging machine cover is very practical; and the materials outside the transparent window of the cover are all metal or other firm materials, are not easy to deform and crack and break, thereby ensuring that the integral quality of the cover is better than that of the original cover.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
