Description

Technical Field

[0001] The utility model belongs to the technical field of sealing and cutting packaging machines, in particular to a sealing and cutting component of an edge sealing machine. Background Art

[0002] The sealing and cutting machine is a fully automatic unmanned packaging machine, which is widely used in the assembly line of mass production packaging. It has high working efficiency and automatic film sealing and cutting. It can be used in conjunction with the automated packaging assembly line and is the first choice for product sealing and heat shrink packaging.

[0003] The sealing and cutting machine is equipped with a horizontal sealing mechanism and a side sealing mechanism for heat sealing different parts. Figure 4 The middle one is the existing transverse sealing mechanism, in which the movement of the upper and lower transverse sealing modules is driven by a cylinder. The reciprocating cycle of the cylinder is long, and the stroke cannot be set arbitrarily. When packaging shorter products, it leads to a lot of waste of cylinder stroke and reduced transverse sealing efficiency. The other is that the linkage is achieved by setting the swing arm connecting rod. When it is necessary to package taller products, the length of the swing arm connecting rod needs to be lengthened, resulting in an increase in the overall working volume of the linkage mechanism in the three dimensions of length, width and height. The structure has large limitations and is not conducive to expansion. Utility Model Content

[0033] like Figure 3 The utility model provides a sealing and cutting assembly of a side sealing machine, comprising: a frame 1, a transverse sealing mechanism 2 and a side sealing mechanism 3. The side sealing mechanism 3 is arranged beside the transverse sealing mechanism 2 and is responsible for different sealing and cutting steps and parts respectively.

[0034] like Figure 1 In the middle is the prior art transverse sealing mechanism D and the prior art side sealing mechanism E.

[0035] Among them, Figure 4 The horizontal sealing mechanism 2 includes a first support plate 20, a support rod 21, an upper sealing and cutting unit 22 and a lower sealing and cutting unit 23. The support rod 21 is vertically fixed on the first support plate 20. The upper sealing and cutting unit 22 and the lower sealing and cutting unit 23 are arranged up and down and slidably connected to the support rod 21. The upper sealing and cutting unit 22 and the lower sealing and cutting unit 23 are prior arts and are not described in detail in this embodiment.

[0036] The upper sealing and cutting unit 22 and the lower sealing and cutting unit 23 are connected via a linkage unit. A driving unit is disposed on the first support plate 20. The driving unit and the linkage unit are drivingly connected to control the opening and closing of the seal.

[0037] More specifically, the linkage unit includes a first connecting rod 4 and a second connecting rod 5 . The first connecting rod 4 and the second connecting rod 5 have a rod portion A at their upper ends and a rack portion B at their lower ends.

[0038] like Figure 4The driving unit includes a first gear 6, a motor 7, a second gear 8, a third gear 9 and a rotating shaft 10. The motor 7 is mounted on the first supporting plate 20 through a motor mounting frame 11. The second gear 8 is fixedly connected to the output end of the motor 7. The rotating shaft 10 is rotatably arranged on the first supporting plate 20 through a bearing seat 12. The third gear 9 is fixed on the rotating shaft 10 and meshed with the second gear 8. The first gear 6 is fixed on both ends of the rotating shaft 10. The first gear 6 is driven to rotate. The upper ends of the first connecting rod 4 and the second connecting rod 5 are respectively fixedly connected to the upper sealing and cutting unit 22 and the lower sealing and cutting unit 23, and the lower ends of the first connecting rod 4 and the second connecting rod 5 are respectively fixedly connected to the upper sealing and cutting unit 22 and the lower sealing and cutting unit 23. The ends are rack parts B respectively meshing with the two sides of the first gear 6, the first connecting rod 4 and the second connecting rod 5 are both arranged vertically, and a limit block 13 is also provided on the rotating shaft 10. When the rotating shaft 10 rotates to a certain angle, the limit block 13 and the first support plate 20 abut against each other. When the limit block 13 abuts against the first support plate 20, the motor 7 needs to stop working to avoid excessive travel. The driving unit also includes a protective frame 14, which is fixed on the first support plate 20, and the first gear 6 and part of the rack part B are located in the protective frame 14. The protective frame 14 ensures that the first connecting rod 4 and the second connecting rod 5 always move in the same vertical line.

On the other hand, the design of the swing arm connecting rod is replaced by the meshing transmission of the gear rack. The gear rotates, and the meshing drives the first connecting rod 4 and the second connecting rod 5 to always move up and down in the same vertical line, thereby driving the upper sealing and cutting unit 22 and the lower sealing and cutting unit 23 to move and seal. When packaging higher products, it is only necessary to extend the length of the first connecting rod 4 and the second connecting rod 5 to meet the requirements. It only increases in the height direction, and the other two dimensions do not need to be changed, and the working volume limitation is relatively small.

[0040] In this embodiment, Figure 5The edge sealing mechanism 3 includes a guide rail 30, a sliding frame 31, a second support plate 32, a third support plate 33 and a manual adjustment unit.

The second support plate 32 and the third support plate 33 are both provided with an edge sealing unit C. The manual adjustment unit can be rotatably connected to the sliding frame 31 and one end is hingedly connected to the upper part of the second support plate 32, and the other end can be shaken to drive the second support plate 32 to move closer to or away from the third support plate 33. Specifically, the manual adjustment unit includes a rotating wheel 34, a handle 35 and a connecting handle 36. The rotating wheel 34 is rotatably connected to the upper part of the sliding frame 31, and one side of the rotating wheel 34 is fixedly connected to the handle 35. The eccentricity of the rotating wheel 34 The upper part of the second support plate 32 is hingedly connected to the position by a connecting handle 36, and the handle 35 is shaken to drive the rotating wheel 34 to rotate, thereby driving the second support plate 32 to move up and down. Secondly, the edge sealing mechanism 3 also includes a hand wheel 37 and a screw rod 38. The screw rod 38 vertically passes through the guide rail 30 and the sliding frame 31. The hand wheel 37 is fixedly connected to the top of the screw rod 38 and is rotatably connected to the upper end of the guide rail 30, driving the edge sealing mechanism 3 to rise and fall as a whole, which can not only meet the edge sealing requirements of products of different heights, but also can change the traditional fixed plate into a second support plate 32 and a third support plate 33 that can be detachably moved. The second support plate 32 and the third support plate 33 are driven to lean against or separate through the manual adjustment unit, which is convenient for the later maintenance and replacement of the edge sealing unit, and reduces the difficulty and cost of maintenance.

[0041] The embodiments of the present application are described above in conjunction with the accompanying drawings.
