[0002] Chinese patent application CN215623191U discloses a plastic film continuous sealing machine. In actual production operations, the same plastic film continuous sealing machine may need to seal plastic packaging bags of different sizes, so that the use cost is reduced. However, the existing film sealing machine still has the following problems in the continuous sealing process: the conveying table and the frame are separate structures, so when the conveying table is against the frame, there is always a large gap between the conveying wheel and the facing surface of the conveying table. However, the capacity of the film bags is different. For example, when a small-capacity film bag is moving, the large gap can easily cause the film bag to lag behind in movement speed or fall into the gap, thereby affecting the sealing efficiency of the film bag.

DETAILED DESCRIPTION

[0017] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0018] See also Figure 1-4 The utility model provides an embodiment: an automatic film sealing machine, comprising a frame 1, a protective cover 2 installed above the frame 1, and a support member 3 is provided below the frame 1; the support member 3 comprises a support plate 30, and both ends of the support plate 30 are connected to the frame 1 through a connecting member 31; the connecting member 31 comprises a support column 35, and the support column 35 passes through the support plate 30 through a screw rod 34 and is connected to a nut 32.

[0019] In summary, by adjusting the gap between the support plate 30 and the conveying wheel, the support plate 30 is brought close to the conveying wheel to meet the sealing requirements of small-capacity film bags; when the gap between the support plate 30 and the conveying wheel is enlarged, the device can seal large-capacity film bags. Based on this, the utility model adjusts the position of the support plate without affecting the movement of the film bag so that the support plate can carry film bags of different capacities.

[0020] Furthermore, since a stud 36 is provided on one side of the nut 32 facing the screw rod 34, wherein the outer side surface of the stud 36 is threadedly engaged with the limiting plate 33, and the inner wall surface of the stud 36 is threadedly engaged with the screw rod 34, when the stud 36 passes through the support plate 30, the limiting plate 33 can ensure that the support plate 30 is clamped together by the limiting plate 33 and the nut 32, and then when the inner wall surface of the stud 36 rotates outside the screw rod 34, the support plate 30 can be driven to approach or move away from the conveying wheel, so the adjustment of the gap between the support plate 30 and the conveying wheel can be achieved through a simple mechanical structure.

[0021] Furthermore, since the size of the end of the support column 35 facing the support plate 30 is larger than the size of the limit plate 33, the end face of the support column 35 can be used to limit the support plate 30 from approaching the conveying wheel without restriction, thereby avoiding the problem of wear and abnormal noise of the support plate 30 and the conveying wheel caused by the support plate 30 sticking to the conveying wheel during operation.

[0022] On the basis of the above scheme, since the support member 3 is movably mounted on the cover plate 5, and the cover plate 5 is movably mounted on the frame 1, the motor and other electrical components inside the frame 1 can be repaired and maintained by disassembling the cover plate 5, and the assembly of the equipment is also facilitated during the production process.

[0023] In order to improve the stability of the support member 3 during operation, a support leg 4 is further provided under the cover plate 5; wherein the upper surface of the support leg 4 contacts the lower surface of the support member 3, and the lower surface of the support leg 4 contacts the ground through a rubber pad 6 provided.

[0024] Among them, the specific structure of the support plate 30 is as follows: the support plate 30 includes a vertical plate 37; the bottom of the vertical plate 37 is in contact with the support leg 4 through a provided pad 38, and the upper end of the vertical plate 37 uses a provided support plate 310 to support the film bag. In actual production, the sheet metal process is used to form the support plate 30, so that the support plate 30 has sufficient strength while being easy to produce and process. In particular, the sheet metal process technology is mature, so the processing time and processing cost of the support plate 30 can be reduced.

[0025] In addition, since a bending plate 39 is provided at one end of the supporting plate 310 away from the vertical plate 37 , the problem of the film bag being scratched by the edge of the supporting plate 310 when moving can be reduced.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
