Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a side sealing device for a tissue box forming machine. Background Technology

[0002] Existing technologies for packaging tissues use either direct-push forming or rotary forming, ensuring that the tissue packaging is completed within the same vertical plane. However, high-speed glue guns cannot bend their glue delivery tubes and are unsuitable for high-speed movement, making them unsuitable for direct-push or rotary forming methods. This hinders the application of glue to the side seals of the outer packaging material. Consequently, tissue packaging requires an outer packaging material with an adhesive coating, along with a side-sealing heat press, to meet the requirements of this method. This not only increases the pre-coating process on the outer packaging material but also raises production costs. Utility Model Content

[0003] The purpose of this invention is to provide a side sealing device for a tissue paper packaging forming machine, which aims to solve the problem in the prior art that it is impossible to spray adhesive on the side sealing position of the tissue paper outer packaging material.

[0005] Furthermore, the lower sealing conveyor is provided with a lower folding mechanism adjacent to the glue spray gun on one side, and the upper sealing conveyor is provided with an upper folding mechanism opposite to the lower folding mechanism on one side.

[0006] Furthermore, the lower side sealing conveyor includes a lower side sealing machine box and a lower conveyor synchronous belt. The glue spray gun is vertically arranged on one side of the lower side sealing machine box and located on one side of the feeding pressure plate. The lower folding mechanism is arranged on one side of the lower side sealing machine box near the glue spray gun. The lower conveyor synchronous belt is arranged on the upper surface of the lower side sealing machine box along the length direction of the lower side sealing machine box.

[0007] Furthermore, the lower folding mechanism includes a lower connecting slide plate, a lower folding pressure plate, and a lower swing motor. The lower connecting slide plate is vertically mounted on one side of the lower side sealing machine housing via a guide rail slider. The lower folding pressure plate is parallel to and close to the side end face of the lower side sealing machine housing. The lower end of the lower folding pressure plate is connected to the upper end of the lower connecting slide plate. The lower swing motor is located at the bottom of the lower side sealing machine housing. The shaft end of the lower swing motor is provided with an eccentric wheel. The eccentric wheel is connected to the lower connecting slide plate via a swing linkage assembly, which drives the lower connecting slide plate to move vertically and linearly back and forth.

[0008] Furthermore, the upper side sealing conveyor includes an upper side sealing machine box and an upper conveying synchronous belt. The upper folding mechanism is disposed on one side of the upper side sealing machine box and located on one side of the feeding pressure plate.

Bearing seats are provided at both ends of the upper connecting slide plate. The upper end of the upper folding pressure plate is rotatably connected to the bearing seats via a swing shaft. A swing shaft motor is provided at one end of the swing shaft for driving the upper folding pressure plate to flip. The upper swing motor is located at the upper end of the upper side sealing machine box. The shaft end of the upper swing motor is connected to the upper connecting slide plate via a swing linkage assembly for driving the upper connecting slide plate to move vertically back and forth.

[0010] Furthermore, the upper side sealing conveyor can be vertically mounted above the lower side sealing conveyor.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] As shown in Figures 1 to 4, a side sealing device for a tissue packaging forming machine includes a mounting base plate 10, a lower side sealing conveyor 20, an upper side sealing conveyor 30, two feeding pressure plates 40, and a glue spray gun 50.

[0029] The mounting base plate 10 is used to install on the frame of the side sealing station of the tissue paper packaging forming machine. The lower side sealing conveyor 20 is set on the mounting base plate 10. The upper end face of the lower side sealing conveyor 20 is provided with a lower conveying synchronous belt 21. The upper side sealing conveyor 30 is mounted on the lower side sealing conveyor 20 at intervals. The lower end face of the upper side sealing conveyor 30 is provided with an upper conveying synchronous belt 31.

[0030] Two feeding plates 40 are arranged opposite to each other and parallel to each other on the same end face of the lower side sealing conveyor 20 and the upper side sealing conveyor 30, and form a feeding port on one side of the tissue paper between the two feeding plates 40, so that the tissue paper wrapped with packaging material can enter between the lower side sealing conveyor 20 and the upper side sealing conveyor 30 from the feeding port.

[0031] A glue spray gun 50 is vertically mounted on the side end face of the lower side sealing conveyor 20, and is positioned near the end of the feed plate 40 on the lower side sealing conveyor 20. It is used to spray glue onto the bottom surface of the packaging material being passed through. This glue spray gun 50 is a high-speed glue spray gun 50.

[0032] In practice, tissues wrapped in packaging material enter between the lower side-sealing conveyor 20 and the upper side-sealing conveyor 30 through the feed inlet, and are transported by the lower conveyor synchronous belt 21 and the upper conveyor synchronous belt 31.

[0033] During operation, the packaging material protruding from the lower conveyor belt 21 passes through the glue spray gun 50. The glue spray gun 50 sprays glue in a straight line onto the bottom surface of the packaging material protruding from the lower conveyor belt 21. Since the glue spray gun 50 is fixed and the packaging material moves with the belt, the problem of spraying glue onto the side seal of the outer packaging material of the tissue box is solved. The hot melt glue sprayed by the glue spray gun 50 forms a line on the packaging material.

[0034] In this embodiment, the lower sealing conveyor 20 is provided with a lower folding mechanism adjacent to the glue gun 50 on one side, and the upper sealing conveyor 30 is provided with an upper folding mechanism opposite to the lower folding mechanism on one side.

[0035] In practice, the packaging materials protruding from the side edges of the upper conveyor belt 31 and the lower conveyor belt 21 can be stacked together using the lower folding mechanism and the upper folding mechanism, and the side panels of the packaging materials can be glued and sealed with adhesive.

[0036] In this embodiment, the lower side sealing conveyor device 20 includes a lower side sealing machine box 22 and a lower conveyor synchronous belt 21. The glue gun 50 is vertically arranged on one side of the lower side sealing machine box 22 and located on one side of the feeding pressure plate 40. The lower folding mechanism is arranged on one side of the lower side sealing machine box 22 near the glue gun 50. The lower conveyor synchronous belt 21 is arranged on the upper end face of the lower side sealing machine box 22 along the length direction of the lower side sealing machine box 22.

[0037] The lower folding mechanism includes a lower connecting slide plate 23, a lower folding pressure plate 24, and a lower swing motor 3725. The lower connecting slide plate 23 is vertically mounted on one side of the lower side sealing machine box 22 via a guide rail slider. The lower folding pressure plate 24 is parallel to and close to the side end face of the lower side sealing machine box 22. The lower end of the lower folding pressure plate 24 is connected to the upper end of the lower connecting slide plate 23. The lower swing motor 3725 is located at the bottom of the lower side sealing machine box 22. The shaft end of the lower swing motor 3725 is provided with an eccentric wheel 26. The eccentric wheel 26 is connected to the lower connecting slide plate 23 via a swing linkage assembly, which is used to drive the lower connecting slide plate 23 to move vertically and linearly back and forth.

[0038] In this embodiment, the upper side sealing conveyor device 30 includes an upper side sealing machine box 32 and an upper conveying synchronous belt 31. The upper folding mechanism is disposed on one side of the upper side sealing machine box 32 and located on one side of the feeding pressure plate 40. The upper conveying synchronous belt 31 is disposed on the lower end face of the upper side sealing machine box 32 along the length direction of the upper side sealing machine box 32.

[0039] The upper folding mechanism includes an upper connecting slide plate 33, an upper folding pressure plate 34, and an upper swing motor 35. The upper connecting slide plate 33 is vertically mounted on one side of the upper sealing housing 32 via a guide rail slider. Bearing seats 36 are provided at both ends of the upper connecting slide plate 33. The upper end of the upper folding pressure plate 34 is rotatably connected to the bearing seats 36 via a swing shaft. A swing shaft motor is provided at one end of the swing shaft to drive the upper folding pressure plate 34 to rotate.

[0040] The motor 35 is located at the upper end of the upper sealing box 32. The shaft end of the upper swing motor 35 is connected to the upper connecting slide plate 33 through the swing linkage assembly, which is used to drive the upper connecting slide plate 33 to move vertically and reciprocally.

[0041] In practical implementation, since the hot melt adhesive sprayed by the glue gun 50 forms a line on the bottom surface below the packaging material, the lower side sealing conveyor 20 and the upper side sealing conveyor 30 stop when the packaging material wrapped with paper towels moves between the upper folding mechanism and the lower folding mechanism. The lower folding pressure plate 24 folds the packaging material sprayed with hot melt adhesive on one side of the lower conveyor timing belt 21 upwards, while the upper folding pressure plate 34 folds the upper conveyor timing belt upwards.

[0042] 31 The packaging material on one side is folded down, and the upper packaging material covers the lower packaging material sprayed with hot melt adhesive. The upper folding edge pressure plate 34 and the lower folding edge pressure plate 24 move back and forth in a straight line, so that the packaging materials are bonded together by hot melt adhesive, so that the packaging material wraps the tissue paper on four sides: top, bottom, front, and back. The wrapped tissue paper is then sent to the discharge position by the lower conveyor synchronous belt 21 and the upper conveyor synchronous belt 31.

[0043] In this embodiment, the upper side sealing conveyor 30 is vertically and flexibly positioned above the lower side sealing conveyor 20.

[0044] Specifically, the upper sealing box 32 has vertical lifting guide rods 38 at both ends. The lower end of the lifting guide rod 38 guides through the mounting base plate 10 and is connected by a lifting connecting rod. The bottom of the mounting base plate 10 is provided with a screw jack 39 connected to the lifting connecting rod.

[0045] In practical implementation, the upper side sealing conveyor 30 is flexibly mounted on the mounting base plate 10 via a lifting connecting rod and a screw lift 39, which facilitates the adjustment of the interval between the upper side sealing conveyor 30 and the lower side sealing conveyor 20, thereby meeting the paper towel packaging requirements of different heights.

[0046] In this embodiment, the feeding ends of the two feeding plates 40 are provided with adsorption plates 41. The adsorption plates 41 can vertically adsorb the packaging material onto the ends of the two feeding plates 40, so that the paper towel can be wrapped on one side by the packaging material.

[0047] In this embodiment, a push-out port 60 is provided between the lower side sealing conveyor 20 and the upper side sealing conveyor 30, and on the side away from the two feeding pressure plates 40, for sending out the paper that has been side sealed and entering the end sealing process.

[0048] The side sealing device of the tissue paper packaging forming machine provided by this utility model, compared with the prior art, forms a side inlet for wrapping tissue paper between two feeding pressure plates 40, and the stacked tissue paper enters from the inlet.

[0049] The material is fed in through the inlet, and the packaging material wraps one side of it. The packaging material on the opposite side protrudes horizontally from the side edge of the upper conveyor belt 31 and the lower conveyor belt 21. The upper conveyor belt 31 and the lower conveyor belt 21 press down on the tissue paper wrapped in the packaging material and move it in a straight line. When it passes the glue spray gun 50, glue can be sprayed in a straight line onto the bottom surface of the packaging material protruding from the lower conveyor belt 21. This solves the problem of spraying glue on the side seal of the outer packaging material wrapping the tissue paper, which can reduce the processing steps of pre-coating the packaging material and save production costs.

[0050] It should be noted that the packaging material mentioned in this embodiment can be packaging paper film or plastic packaging film.

[0051] Where there is no conflict, the above embodiments and features can be combined with each other.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
