As the preferable technical scheme of the utility model, the supporting piece is movably arranged on the cover plate, and the cover plate is movably arranged on the frame.
According to the preferable technical scheme, supporting legs are further arranged below the cover plate, wherein the upper surfaces of the supporting legs are in contact with the lower surfaces of the supporting pieces, and the lower surfaces of the supporting legs are in contact with the ground through rubber pads.
The support plate comprises a vertical plate, the bottom of the vertical plate is contacted with the support legs through a cushion plate, and the upper end of the vertical plate is used for supporting the film bag by a bearing plate.
As the preferable technical scheme of the utility model, one end of the bearing plate, which is far away from the vertical plate, is also provided with a bending plate.
By adopting the technical scheme, the device has the beneficial effects that the supporting plate is close to the conveying wheel by adjusting the gap between the supporting plate and the conveying wheel so as to meet the sealing requirement of the small-capacity film bag, and the device can seal the large-capacity film bag when the gap between the supporting plate and the conveying wheel is enlarged. Based on the above, the utility model can bear film bags with different capacities by adjusting the position of the supporting plate while not influencing the movement of the film bags.

Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1-4, an embodiment of the present utility model provides an automatic film sealing machine, which comprises a frame 1, a protective cover 2 installed above the frame 1, and a support member 3 arranged below the frame 1, wherein the support member 3 comprises a support plate 30, two ends of the support plate 30 are connected with the frame 1 through connecting members 31, the connecting members 31 comprise support columns 35, and the support columns 35 are connected with nuts 32 after passing through the support plate 30 through screws 34.
In summary, by adjusting the gap between the support plate 30 and the conveying wheel, the support plate 30 is made to approach the conveying wheel to meet the sealing requirement of the small-capacity film bag, and when the gap between the support plate 30 and the conveying wheel is enlarged, the device can seal the large-capacity film bag. Based on the above, the utility model can bear film bags with different capacities by adjusting the position of the supporting plate while not influencing the movement of the film bags.
Further, since the screw cap 32 is provided with the stud 36 on a surface facing the screw 34, wherein the outer side surface of the stud 36 is in threaded engagement with the provided limiting piece 33, and the inner wall surface of the stud 36 is in threaded engagement with the screw 34, when the stud 36 passes through the support plate 30 and then is clamped together with the screw cap 32 by the limiting piece 33, the support plate 30 can be driven to approach or separate from the conveying wheel by the inner wall surface of the stud 36 when the screw 34 rotates, and therefore, the gap between the support plate 30 and the conveying wheel can be adjusted by a simple mechanical structure.
Further, since the dimension of the end of the support column 35 facing the support plate 30 is larger than the dimension of the limit plate 33, the end face of the support column 35 can be used to limit the support plate 30 from being infinitely close to the conveying wheel, so that the problems of abrasion and abnormal noise of the support plate 30 and the conveying wheel caused by the adhesion of the support plate 30 to the conveying wheel in the working process can be avoided.
On the basis of the scheme, as the supporting piece 3 is movably arranged on the cover plate 5, and the cover plate 5 is movably arranged on the frame 1, the motor and other electrical components inside the frame 1 can be maintained and maintained through the dismounting cover plate 5, and the equipment is convenient to assemble in the production process.
In order to improve the stability of the support 3 during operation, a support leg 4 is further arranged below the cover plate 5, wherein the upper surface of the support leg 4 is in contact with the lower surface of the support 3, and the lower surface of the support leg 4 is in contact with the ground through a rubber pad 6.
The support plate 30 has a specific structure that the support plate 30 comprises a vertical plate 37, the bottom of the vertical plate 37 is contacted with the support legs 4 through a cushion plate 38, and the upper end of the vertical plate 37 is used for supporting a film bag by a bearing plate 310, and in actual production, the support plate 30 is promoted to be molded by a sheet metal process, so that the support plate 30 has enough strength and is convenient for production and processing of the support plate 30, and particularly, the sheet metal process is mature, so that the processing time and processing cost of the support plate 30 can be reduced.
In addition, since the end of the supporting plate 310 far from the vertical plate 37 is further provided with the bending plate 39, the problem that the film bag is scratched by the corners of the supporting plate 310 during moving can be reduced.
The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
