Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly relates to a facial tissue packaging and forming machine. Background Art

[0002] Currently, in the packaging and forming process of the production and processing of napkin facial tissues, a packaging machine is required to wrap plastic film around the facial tissues. In this process, a conveyor belt is needed to transport the facial tissues and the outer packaging materials for packaging the facial tissues. The outer packaging materials can be divided into plastic packaging films and degradable environmental protection paper films. Since the facial tissues and the outer packaging materials are relatively light in weight, it is easy to cause the packaging of the facial tissues to be unsmooth and unstable during the transportation and packaging process. Therefore, a reciprocating forming mechanism for facial tissues is proposed to solve the above problems.

[0003] In the prior art, the packaging method for facial tissues is straight-push forming or rotary table forming, which makes the packaging and forming of facial tissues all in the same vertical plane. Since the glue delivery pipe of the high-speed glue spray gun cannot be bent and is not suitable for high-speed movement, it is not convenient to realize side-sealing glue spraying on the outer packaging materials. This results in that when packaging and forming facial tissues, outer packaging materials with an adhesive coating are required, and side-sealing ironing plates are needed to cooperate to meet the above-mentioned forming and packaging methods for facial tissues. This not only increases the processing procedure of pre-coating glue on the outer packaging materials, increases the production cost, but also is not conducive to improving the packaging efficiency.

[0036] The present invention will be described in detail below in conjunction with specific embodiments.

[0037] In the present invention, when orientation words appear, these orientation words are for the convenience of describing the present invention 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 should not be construed as limiting the specific protection scope of the present invention.

[0038] In the present invention, unless otherwise clearly specified and defined, when terms such as "set on", "connected", "linked" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or connected through an intermediate medium, and can be internally connected and communicated between two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0039] As Figures 1 to 3 shown, a facial tissue packaging and forming machine includes a machine frame bottom plate 10, a film feeding device 20, a side - sealing and forming conveying device, a loading and pushing device, a discharging and pushing device 80, and a discharging tail frame 90.

[0040] A workbench 11 is provided on the machine frame bottom plate 10, and a machine frame vertical plate 12 is vertically provided on one side of the workbench 11.

[0041] The film feeding device 20 is arranged on one side of the machine frame vertical plate 12 and is used for tensioning and feeding the rolled packaging material. A film cutting mechanism 21 is provided at one end of the film feeding device 20 for feeding out and cutting the packaging material.

[0042] The side-sealing forming conveying device is arranged on the workbench 11 along the length direction of the workbench 11, and is used for spraying glue on the side edges of the packaging material wrapped with paper towels and folding and side-sealing the film.

[0043] The side-sealing forming conveying device includes an upper side-sealing conveying device 30 and a lower side-sealing conveying device 40 which are arranged at an interval up and down. The feeding ends of the upper side-sealing conveying device 30 and the lower side-sealing conveying device 40 are horizontally connected with a feeding pressing plate 50. A film-sucking plate 51 is arranged at the feeding port of the feeding pressing plate 50, and is used for adsorbing the packaging material vertically sent out from the film-cutting mechanism 21.

[0044] On one side of the lower side-sealing conveying device 40, close to the edge of the feeding pressing plate 50, a glue spraying gun 41 is vertically arranged, and is used for spraying glue on the side surface of the passing packaging material. Specifically, it sprays glue on the lower surface of the packaging material whose side edge is exposed in the lower side-sealing conveying device 40, so as to prevent the hot melt adhesive from directly contacting the inner paper towels during film folding and sealing.

[0045] The feeding pushing device is arranged on one side of the vertical plate 12 of the frame and is located below the film-feeding device 20. The feeding pushing device is used for transferring the stacked paper towels to the feeding port of the feeding pressing plate 50, and pushing the stacked paper towels to wrap the vertically adsorbed packaging material, and entering between the upper side-sealing conveying device 30 and the lower side-sealing conveying device 40 from the feeding port of the feeding pressing plate 50.

[0047] The discharging tail frame 90 is arranged on the workbench 11. One end of the discharging tail frame 90 is horizontally connected to the other side of the discharging end of the side-sealing forming conveying device and is arranged opposite to the discharging pushing device 80, and is used for folding and forming the front two sides of the pushed-out packaging material, and heat-sealing and shaping the left and right sides of the packaging material.

[0048] Through the upper side-sealing conveying device 30 and the lower side-sealing conveying device 40 which are distributed at an interval up and down, and cooperating with the vertical glue spraying gun 41 arranged on one side of the lower side-sealing conveying device 40, the side surface of the passing packaging material is sprayed with glue, and the pressing side-sealing after glue spraying on the side edge of the packaging material is completed. Through the relative cooperation of the discharging pushing device 80 and the discharging tail frame 90, the left and right sides of the side-sealed packaging material can be folded and heat-sealed and shaped, so as to complete the complete wrapping of each surface of the paper towels, which can effectively reduce the processing procedures of pre-coating glue on the packaging material, save production costs, and effectively improve the packaging efficiency.

[0049] Such as Figure 1 、 Figure 3 and 4As shown in combination, in this embodiment, the upper side sealing conveying device 30 is disposed on the workbench 11 in a liftable manner and is located above the lower side sealing conveying device 40. The upper side sealing conveying device 30 includes an upper side sealing machine case 31, an upper hemming mechanism 32, and an upper synchronous belt conveying mechanism 33. At both ends of the upper side sealing machine case 31, lifting guide rods 34 are vertically provided. The lower ends of the lifting guide rods 34 are connected by a lifting connecting rod. At the bottom of the workbench 11, a screw lift 35 connected to the lifting connecting rod is provided.

[0050] During specific implementation, the upper side sealing conveying device 30 is disposed on the workbench 11 in a liftable manner through the lifting connecting rod and the screw lift 35, which is convenient for adjusting the spacing distance between the upper side sealing conveying device 30 and the lower side sealing conveying device 40, so as to meet the tissue packaging requirements with different height requirements.

[0051] In this embodiment, the upper hemming mechanism 32 includes an upper connecting slide plate 321, an upper hemming pressing plate 322, and an upper swing motor 323. The upper connecting slide plate 321 is vertically disposed on one side of the upper side sealing machine case 31 through a guide rail slider. Bearing seats 324 are provided at both ends of the upper connecting slide plate 321. The upper end of the upper hemming pressing plate 322 is rotatably connected to the bearing seat 324 through a swing shaft 325. One end of the swing shaft 325 is provided with a swing shaft 325 motor for driving the upper hemming pressing plate 322 to flip.

[0054] Among them, the lower hemming mechanism 43 includes a lower connecting sliding plate 431, a lower hemming pressing plate 432 and a lower swing motor 433. The lower connecting sliding plate 431 is vertically arranged on one side of the lower side sealing machine box 42 through a guide rail slider. The lower hemming pressing plate 432 is arranged parallel to and close to the side end face of the lower side sealing machine box 42. The lower end of the lower hemming pressing plate 432 is connected to the upper end of the lower connecting slider. The lower swing motor 433 is arranged at the bottom of the lower side sealing machine box 42. An eccentric wheel 434 is arranged at the shaft end of the lower swing motor 433.

[0055] In specific implementation, when the packaging material half-wrapping the paper towels moves to the station of the lower hemming mechanism 43, the glue spraying gun 41 sprays glue linearly on the lower surface of the passing packaging material. When it is sent to the station of the lower hemming mechanism 43, the lower swing motor 433 drives the lower connecting sliding plate 431 to rise, presses and folds the packaging material below the side sealing position upward, and completely folds it with the upper packaging material.

[0056] Such as Figure 1 、 Figure 6 and Figure 7 As shown in combination, in this embodiment, the feeding and pushing device includes a feeding mechanism 60 and a pushing mechanism 70. The feeding mechanism 60 is vertically arranged on one side of the frame vertical plate 12. The upper end of the feeding mechanism 60 is close to the feeding end of the feeding pressing plate 50. The pushing mechanism 70 is horizontally arranged on one side of the frame vertical plate 12. The feeding mechanism 60 and the pushing mechanism 70 are arranged at a vertical angle.

[0057] In specific implementation, the feeding mechanism 60 is used for feeding the stacked paper towels and sending the stacked paper towels to the feeding port of the feeding pressing plate 50. The pushing mechanism 70 is used for pushing the stacked paper towels at the feeding port of the feeding pressing plate 50 towards the vertically adsorbed packaging material for wrapping and feeding them into the space between the upper side sealing conveying device 30 and the lower side sealing conveying device 40 from the feeding port of the feeding pressing plate 50.

[0058] In this embodiment, the feeding mechanism 60 includes a vertical mounting base 61, a material discharging box 62, and a pressing plate 64.

At this time, the stacked paper towels are close to the side of the vertically adsorbed packaging material. The stacked paper towels are pushed towards the vertically adsorbed packaging material for wrapping through the pushing mechanism 70, and then are fed into the space between the upper side sealing conveying device 30 and the lower side sealing conveying device 40 from the feeding port of the feeding pressing plate 50.

The pushing connecting rod 72 makes a linear reciprocating movement in the length direction of the horizontal mounting base 71 through a guide rail slider and a connecting rod driving mechanism, and can drive the pushing plate 73 to extend into the feeding pressing plate 50.

[0061] During specific implementation, the pushing connecting rod 72 makes a linear reciprocating movement in the length direction of the horizontal mounting base 71 through a guide rail slider and a connecting rod driving mechanism, so as to drive the pushing plate 73 at the end of the pushing connecting rod 72 to make a linear reciprocating movement. The stacked paper towels sent to the top of the material discharging box 62 are pushed towards the vertically adsorbed packaging material and into the space between the upper side sealing conveying device 30 and the lower side sealing conveying device 40 through the pushing plate 73.

[0062] As Figure 2 and Figure 9As shown in combination, in this embodiment, the discharging and pushing device 80 includes a discharging guide rail mounting plate 81, a discharging slide plate 82, and a discharging connecting rod 83.

The end of the discharging push rod 84 is provided with a rear folding plate 85, and a pushing insertion angle member 86 with an end bent outward is arranged on the outer side of the rear folding plate 85.

[0063] During specific implementation, after the side sealing of the packaging material of the stacked paper towels is completed, it is sent to the discharging port by the upper side sealing conveying device 30 and the lower side sealing conveying device 40, and when it is at the working station of the discharging and pushing device 80, the discharging slide plate 82 drives the discharging push rod 84 on the discharging connecting rod 83 to perform linear movement, and the edges of the packaging material that are not folded on both sides are folded from the rear of the packaging material through the rear folding plate 85, and at the same time, it is pushed into the feeding port of the discharging tail frame 90.

[0064] In addition, the discharging push rod 84 can adjust the spacing distance on the discharging connecting rod, so as to adapt to paper towel packages of different lengths.

[0066] Such as Figures 1 to 10As shown in the figure, in specific implementation: Place the stacked paper towels on the top plate 63 inside the feeding box 62. The top plate 63 drives the stacked paper towels to rise to the top of the feeding box 62, and the top of the stacked paper towels is pressed by the pressing plate 64. At this time, the stacked paper towels are close to the side of the vertically adsorbed packaging material. The stacked paper towels are pushed towards the vertically adsorbed packaging material for wrapping through the pushing mechanism 70, and then sent into the forming channel between the upper side-sealing conveying device 30 and the lower side-sealing conveying device 40 from the feeding port of the feeding pressing plate 50. At the same time, the film cutting mechanism 21 cuts and separates one end of the packaging material. The upper synchronous belt conveying mechanism 33 and the lower synchronous belt conveying mechanism 44 simultaneously drive the stacked paper towels partially wrapped by the packaging material to move from the feeding position to the side-sealing station. During the movement of the synchronous belt, the lower packaging material passes through the hot melt adhesive gun 41, and the hot melt adhesive gun 41 sprays hot melt adhesive onto the packaging material on the side of the lower synchronous belt conveying mechanism 44. Since the hot melt adhesive gun 41 is fixed and the packaging material moves with the synchronous belt, the hot melt adhesive sprayed by the hot melt adhesive gun 41 forms a line on the packaging material. When the upper and lower synchronous belt conveying mechanisms move to the side-sealing position and stop, the lower folding pressing plate 432 folds the packaging material sprayed with hot melt adhesive on the side of the lower conveying synchronous belt conveying mechanism upwards, and at the same time, the upper folding pressing plate 322 folds the packaging material on the side of the upper conveying synchronous belt conveying mechanism downwards. The upper packaging material covers the lower packaging material sprayed with hot melt adhesive. The upper folding pressing plate 322 and the lower folding pressing plate 432 perform reciprocating linear movement up and down, so that the packaging materials are bonded together by the hot melt adhesive, enabling the packaging material to form upper, lower, front, and rear four-sided wrapping on the stacked paper. The wrapped stacked paper towels are then sent to the discharging position by the upper synchronous belt conveying mechanism 33 and the lower synchronous belt conveying mechanism 44. The wrapped stacked paper towels are pressed and folded from the rear by the rear folding plate 85 and the movable corner inserts and pushed into the discharging tail frame 90. When entering the feeding port of the discharging tail frame 90, the packaging material in front of the stacked paper towel packaging material that has not been pressed and folded will first be pressed and folded by the front folding plate 91, so that the edges of the packaging materials on both sides of the packaging material in the front and rear directions are pressed together. Then, the packaging materials in the up and down directions are pressed together through the folding guide grooves 93 on both sides of the stacking and forming section. Then, through the high-temperature heat-sealing conveyor belt mechanisms 95 on both sides of the heat-sealing section 94, the two sides of the pressed packaging materials are heat-sealed and formed. Finally, the packaged stacked paper towels are sent out through the discharging end of the discharging tail frame 90.
