Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a double-rotating wheel packaging mechanism for ice cream paper packages. Background Art

[0002] Currently, most of the ice cream packaging on the market is plastic heat-sealed packaging. On the one hand, this type of packaging is not environmentally friendly. On the other hand, when the plastic is heated and sealed, it will produce toxic and harmful substances, which are harmful to the human body.

[0003] In addition, there are also ice creams on the market that are packaged in wax paper, but they are generally packaged by manual twisting. The packaging process has problems such as high consumption of manpower and material resources, low production efficiency, irregular appearance, and loose packaging.

[0004] Patents with publication numbers CN104401524B and CN113086326A both involve ice cream paper wrapping machines, but they do not properly handle the details of folding and wrapping the wax paper on each side of the ice cream, and there is a situation where the whole process is done in one step. For example, the ice cream wax paper wrapping machine proposed in publication number CN104401524B proposes that "the paper feeding mechanism feeds and cuts the wax paper, and the ice cream passes through the paper feeding mechanism at the same time. The cut wax paper is just wrapped on the ice cream, and then the ice cream is fed into the winding paper machine, and the wax paper on the ice cream is bent and rotated to be fixed to the ice cream stick, thereby achieving the purpose of automatically wrapping the ice cream with wax paper." The ice cream packaged by the prior art is as follows: Figure 1 In the two forms, the packaged ice cream generally has problems such as the wax paper on each side is not firmly bonded, and there are still problems such as irregular appearance and loose packaging. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention proposes a double-rotor packaging mechanism for ice cream paper packages, which can orderly fold, compact and bond the packaging paper on each side of the ice cream during the packaging process, so that the packaged ice cream has a neat appearance and is tightly packaged.

At this time, the wrapping paper at the front and rear end faces of the ice cream has completed folding; in addition, when the ice cream enters the U-shaped clamping opening of the second die box, under the action of the folding elastic sheet, the front end of the ice cream abuts against the folding plate. Since the length dimension of the ice cream is different in actual production, this can make the product effect of the paper wrapping better and more regular.

When the second turntable rotates, the two spring clamping arms gradually close, and fold the wrapping paper at the upper and lower edges of the rear end surface of the ice cream, and clamp the wrapping paper on the wooden handle. Under the clamping action of the two spring clamping arms, the adhesive on the wrapping paper makes the wrapping paper adhere to the wooden handle of the ice cream, thereby completing the paper package on the rear end surface of the ice cream.

[0023] As can be seen from the above technical solutions, a double-rotor packaging mechanism for ice cream paper bags provided by the present invention has the following beneficial effects: When wrapping ice cream with paper bags, the double-rotor packaging mechanism is used to fold the wrapping paper to complete the ice cream paper bag.

The inner side of the fan-shaped folding paper board 36 is in clearance contact with the front end face of the second die box 33, and a plurality of pressing rollers 37 are installed on the fan-shaped folding paper board 36 in a scattered manner.

[0052] As Figure 8 and 9 shown in the figure, in this embodiment, the rear-end paper folding mechanism includes a clamping arm mechanism 7. The clamping arm mechanism 7 is arranged on the rear side of the second turntable 31. The clamping arm mechanism 7 includes a planar groove cam 71, a positioning disk 72, and a plurality of mechanical clamping arms 73. The planar groove cam 71 is fixedly connected to the second turntable support cylinder 32, and a curve groove is provided on the planar groove cam 71. The positioning disk 72 is fixedly connected to the second turntable 31. The mechanical clamping arm 73 includes a Y-shaped push rod 731 and two spring clamping arms 732. One end of the Y-shaped push rod 731 is slidably connected to the curve groove of the planar groove cam 71, and the two spring clamping arms 732 are symmetrically installed at the other end of the Y-shaped push rod 731. A plurality of radial sliding grooves are provided on the positioning disk 72, and the plurality of radial sliding grooves are scattered. The plurality of Y-shaped push rods 731 are correspondingly arranged in the plurality of radial sliding grooves one by one.

[0053] The working principle of this embodiment:

[0054] When using this double - rotating wheel packaging mechanism to wrap the ice cream 8 with paper, the first turntable 21 of the first turntable mechanism 2 rotates until the U - shaped clamping opening 4 of one of the first die - boxes 23 faces horizontally to the right, which is connected to the previous process. The paper feeding mechanism in the previous process transports the packaging paper 9 downward to the designated position. The glue - spraying machine in the previous process applies glue to the packaging paper 9. The pushing mechanism in the previous process pushes the ice cream 8 to contact the packaging paper 9. The first push - rod mechanism 24 on the right side of the first turntable 21 passes through the first die - box 23 and contacts the packaging paper 9. The previous process pushes the ice cream 8 into the first die - box 23. The left side of the ice cream 8 is attached to the packaging paper 9 and carries the packaging paper 9 into the first die - box 23. The first push - rod mechanism 24 retracts to assist the previous process in pushing the ice cream 8;

[0055] During the process of the ice cream 8 carrying the packaging paper 9 into the U - shaped clamping opening 4 of the first die - box 23, the folding plate 5 on the first die - box 23 folds the packaging paper 9 at the left - hand edge of the front end face of the ice cream 8. The packaging paper 9 at the upper and lower edges of the front end face of the ice cream 8 is stuck into the gap between the folding plate 5 and the first die - box 23, so that the packaging paper 9 forms folds at the left - hand edge end - corners of the front end face of the ice cream 8 respectively. At the same time, the folding spring piece 6 folds the packaging paper 9 at the left - hand edge of the rear end face of the ice cream 8. The packaging paper 9 at the upper and lower edges of the rear end face of the ice cream 8 is stuck into the gap between the folding spring piece 6 and the first die - box 23, so that the packaging paper 9 forms folds at the left - hand edge end - corners of the rear end face of the ice cream 8 respectively. In addition, when the ice cream 8 enters the U - shaped clamping opening 4 of the first die - box 23, under the action of the folding spring piece 6, the front end of the ice cream 8 abuts against the folding plate 5. Since the length dimension of the ice cream 8 varies in actual production, this can make the product effect of the paper - wrapped product better and more regular;

[0056] During the process of the ice cream 8 entering the first die - box 23, the first die - box 23 folds the packaging paper 9, and the left side, top side, and bottom side of the ice cream 8 are all wrapped by the packaging paper 9;

[0057] When the ice cream 8 carrying the packaging paper 9 completely enters the U - shaped clamping opening 4 of the first die - box 23, the first turntable 21 rotates counter - clockwise, and the drive motor drives the first folding cardboard 26 to move upward. The first folding cardboard 26 folds the packaging paper 9 at the lower edge of the right side of the ice cream 8. The ice cream 8 rotates counter - clockwise with the first turntable 21, and the arc - shaped cover 25 folds the packaging paper 9 at the upper edge of the right side of the ice cream 8. The packaging paper 9 at the upper edge is folded and covers the packaging paper 9 folded at the lower edge, so that the packaging paper 9 forms an adhesive area overlapping each other on the right side of the ice cream 8. The first folding cardboard 26 swings downward and retracts, thus completing the folding of the packaging paper 9 on the right side of the ice cream 8 and wrapping the ice cream 8;

[0058] After the first turntable 21 rotates the ice cream 8 by 180°, the U-shaped clamping opening 4 of the first mold box 23 carrying the ice cream 8 faces horizontally to the left and is horizontally opposite to the U-shaped clamping opening 4 of one of the second mold boxes 33 on the second turntable 31. The first push rod mechanism 24 on the left side of the first turntable 21 penetrates into the first mold box 23 and pushes the ice cream 8 to the left. The second push rod mechanism 34 on the right side of the second turntable 31 penetrates out of the second mold box 33 and contacts the side surface of the ice cream 8 in the first mold box 23. During the movement of the ice cream 8 in the first mold box 23 into the second mold box 33, under the clamping action of the first push rod mechanism 24 and the second push rod mechanism 34, the second push rod mechanism 34 compacts the adhesive area on the side surface of the ice cream 8, so that the adhesive provided in the adhesive area bonds and fixes the two layers of wrapping paper 9;

[0059] During the process of the ice cream 8 carrying the wrapping paper 9 entering the U-shaped clamping opening 4 of the second mold box 33, the folding angle plate 5 on the second mold box 33 folds the wrapping paper 9 at the left edge of the front end surface of the ice cream 8. The upper and lower edges of the wrapping paper 9 on the front end surface of the ice cream 8 are stuck into the gap between the folding angle plate 5 and the second mold box 33, so that the wrapping paper 9 forms folding angles at the left edge end corners of the front end surface of the ice cream 8 respectively. At the same time, the folding angle elastic piece 6 folds the wrapping paper 9 at the left edge of the rear end surface of the ice cream 8. The upper and lower edges of the wrapping paper 9 on the rear end surface of the ice cream 8 are stuck into the gap between the folding angle elastic piece 6 and the second mold box 33, so that the wrapping paper 9 forms folding angles at the left edge end corners of the rear end surface of the ice cream 8 respectively. At this time, the wrapping paper 9 at the front and rear end surfaces of the ice cream 8 has completed folding angles. In addition, when the ice cream 8 enters the U-shaped clamping opening 4 of the second mold box 33, under the action of the folding angle elastic piece 6, the front end of the ice cream 8 abuts against the folding angle plate 5. Since the length dimension of the ice cream 8 has differences in actual production, doing so can make the product wrapped by the paper have a better and more regular effect;

[0060] When the ice cream 8 carrying the wrapping paper 9 completely enters the U-shaped clamping opening 4 of the second mold box 33 and the second turntable 31 rotates clockwise, when the ice cream 8 rotates to the second folding cardboard 35, the drive motor drives the second folding cardboard 35 to flip. The second folding cardboard 35 folds the wrapping paper 9 at the upper edge of the front end surface of the ice cream 8. The ice cream 8 rotates clockwise with the second turntable 31, and the fan-shaped folding cardboard 36 folds the wrapping paper 9 at the lower edge of the front end surface of the ice cream 8. The wrapping paper 9 at the lower edge is folded and covers the wrapping paper 9 folded at the upper edge, so that the wrapping paper 9 forms an overlapping adhesive area on the front end surface of the ice cream 8. The second folding cardboard 35 flips and swings back, thus completing the folding and wrapping of the wrapping paper 9 on the front end surface of the ice cream 8 around the ice cream 8. When the second mold box 33 carrying the ice cream 8 rotates past the pressing roller 37, the multiple pressing rollers 37 compact the adhesive area on the front end surface of the ice cream 8 multiple times, so that the adhesive provided in the adhesive area bonds and fixes the two layers of wrapping paper 9;

[0061] When the ice cream 8 with the wrapping paper 9 completely enters the U-shaped clamping opening 4 of the second die box 33 and the second turntable 31 rotates clockwise, the positioning disk 72 rotates with the second turntable 31. The positioning disk 72 drives each mechanical clamping arm 73 to rotate. The Y-shaped push rod 731 of the mechanical clamping arm 73 slides in the curve groove of the planar groove cam 71. Under the action of the planar groove cam 71, the Y-shaped push rod 731 reciprocates radially in the radial sliding groove, thereby controlling the opening and closing of the two spring clamping arms 732. When the ice cream 8 enters the U-shaped clamping opening 4 of the second die box 33, the wooden handle of the ice cream 8 is stuck into the folding elastic piece 6. At this time, the two spring clamping arms 732 of the mechanical clamping arm 73 corresponding to the second die box 33 are in an open state. When the second turntable 31 rotates, the two spring clamping arms 732 gradually close and fold the wrapping paper 9 at the upper and lower edges of the rear end face of the ice cream 8, clamping the wrapping paper 9 on the wooden handle. Under the clamping action of the two spring clamping arms 732, the adhesive provided on the wrapping paper 9 makes the wrapping paper 9 adhere to the wooden handle of the ice cream 8, thereby completing the paper wrapping of the rear end face of the ice cream 8.

[0062] When paper wrapping the ice cream 8, the double turntable encapsulation mechanism is used to fold the wrapping paper 9 to complete the paper wrapping of the ice cream 8. During the entire paper wrapping process, the first turntable mechanism 2 and the second turntable mechanism 3 each have their own division of labor, orderly folding and compacting and adhering the wrapping paper 9 on each side of the ice cream 8. Each folding process is closely coordinated, with a short stagnation time and a good packaging operation rhythm, significantly improving the paper wrapping efficiency. The double turntable encapsulation mechanism has in-place details in folding the wrapping paper 9 to package the ice cream 8. The packaged ice cream 8 has a regular appearance, the wrapping paper 9 on each side is firmly adhered, and the packaging is tight. It should be noted here that in addition to being able to paper wrap the ice cream 8, this double turntable encapsulation mechanism can also be applied to the production and processing of square products such as ice cream 8. Square products include but are not limited to Sachima and puffed rice candy. Although Sachima and puffed rice candy do not include a wooden handle structure, it can be imagined that by referring to the paper folding structure of the front end face of the ice cream 8 and making slight improvements to the first turntable mechanism 2 and the second turntable mechanism 3, it is possible to achieve the paper wrapping of Sachima and puffed rice candy without a wooden handle.
