Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical equipment, and particularly relates to an ice cream paper wrapping machine. Background Art

[0002] Currently, most ice cream packages on the market are plastic heat-sealed packages. On the one hand, this kind of packaging is not environmentally friendly. On the other hand, toxic and harmful substances will be generated when the plastic is heat-sealed, which is harmful to the human body. In addition, there are also ice creams on the market using wax paper packaging, but generally the manual twisting method is used for packaging. There are problems such as high consumption of manpower and material resources, low production efficiency, irregular appearance molding, and loose packaging in the packaging process.

[0003] The patents with publication numbers CN104401524B and CN113086326A both relate to ice cream paper wrapping machines, but their detailed processing of the wax paper folding and encapsulation on each side of the ice cream is not in place, and there is a situation of one-step completion. For example, an ice cream wax paper wrapping machine proposed in the patent with publication number CN104401524B has a packaging method similar to the traditional manual packaging process, only using mechanical automation for packaging, which improves the production efficiency. However, whether it is the traditional manual packaging process or the technical solutions adopted in the above two patents, the wax paper corresponding to each side of the ice cream is not folded in place during the packaging process, the edges and corners are not clear enough, and at the end of the ice cream wooden stick, the rotating wax paper is used to twist it around the wooden stick for encapsulation, as Figure 1 shown; in addition, it is not seen in the public documents that it is strengthened and fixed with glue, and the wax paper at the wooden stick is easy to reverse and open.

[0084] Working principle of this embodiment: When using this paper wrapping machine to wrap ice cream, the eighth belt transmission mechanism 71 is connected to the previous process mechanism of the production line. The ice cream to be wrapped enters the starting end of the belt transmission of the eighth belt transmission mechanism 71 and is conveyed by the eighth belt transmission mechanism 71; the ice cream to be wrapped is conveyed towards the end of the belt transmission of the eighth belt transmission mechanism 71. When multiple ice creams are in place, the multi-to-one pushing mechanism 72 pushes multiple ice creams on the belt conveying surface of the eighth belt transmission mechanism 71 onto the connecting platform 73 at one time, and the connecting platform 73 pushes them onto the belt conveying surface of the first belt transmission mechanism 21;

[0085] The ice cream to be wrapped enters the starting end of the belt transmission of the first belt transmission mechanism 21 and is conveyed by the first belt transmission mechanism 21; during the conveying process, the space between two adjacent baffles of the baffle synchronous belt is a working station for ice cream conveying. The cover plate 25 covers the belt conveying surface, which can ensure the stable conveying of the ice cream and prevent the ice cream from jumping upward during the conveying process; when the ice cream is conveyed to the end of the belt transmission of the first belt transmission mechanism 21, the lifting mechanism 22 lifts the ice cream on the belt to be level with the paper wrapping platform 24, and the pushing mechanism 23 pushes the lifted ice cream onto the paper wrapping platform 24 and continues to push it towards the feeding port of the first rotating wheel mechanism 31;

[0086] While the pushing mechanism 23 pushes the ice cream, the paper tape transmission mechanism 43 vertically conveys the wrapping paper downward, the cutting knife mechanism 44 cuts a section of the wrapping paper, and the cut section of the wrapping paper is continuously conveyed by the paper tape transmission mechanism 43 towards the paper feeding outlet. The glue spraying machine 6 sprays glue on the cut wrapping paper;

[0087] At the same time, the first turntable 311 of the first rotating wheel mechanism 31 rotates to a position where the U-shaped clamping opening of one of the first die boxes 313 is horizontally facing right and level with the paper wrapping platform 24, ready to receive the material. The pushing mechanism 23 pushes the ice cream to contact the wrapping paper at the paper feeding outlet. The first push rod mechanism 314 on the right side of the first turntable 311 passes through the first die box 313 and contacts the wrapping paper at the paper feeding outlet. The pushing mechanism 23 pushes the ice cream into the first die box 313. The left side of the ice cream is attached to the wrapping paper and carries the wrapping paper into the first die box 313. The first push rod mechanism 314 retracts to assist the pushing mechanism 23 in pushing the ice cream;

[0088] During the process of the ice cream carrying the wrapping paper into the U-shaped clamping opening of the first die box 313, the folding plate 33 on the first die box 313 folds the wrapping paper at the left edge of the front end face of the ice cream. The wrapping paper at the upper and lower edges of the front end face of the ice cream is caught in the gap between the folding plate 33 and the first die box 313, so that the wrapping paper forms folds at the left edge end corners of the front end face of the ice cream. At the same time, the folding spring piece 34 folds the wrapping paper at the left edge of the rear end face of the ice cream. The wrapping paper at the upper and lower edges of the rear end face of the ice cream is caught in the gap between the folding spring piece 34 and the first die box 313, so that the wrapping paper forms folds at the left edge end corners of the rear end face of the ice cream. In addition, when the ice cream enters the U-shaped clamping opening of the first die box 313, under the action of the folding spring piece 34, the front end of the ice cream abuts against the folding plate 33. 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. During the process of the ice cream entering the first die box 313, the first die box 313 folds the wrapping paper, and the left side, top side, and bottom side of the ice cream are all wrapped by the wrapping paper;

[0089] When the ice cream carrying the wrapping paper completely enters the U-shaped clamping opening of the first die box 313, the first turntable 311 rotates counterclockwise, and the driving motor drives the first folding cardboard 36 to move upward. The first folding cardboard 36 folds the wrapping paper at the lower edge of the right side of the ice cream. The ice cream rotates counterclockwise with the first turntable 311, and the arc-shaped cover 35 folds the wrapping paper at the upper edge of the right side of the ice cream. The wrapping paper at the upper edge is folded and covers the wrapping paper folded at the lower edge, so that the wrapping paper forms an overlapping bonding area on the right side of the ice cream. The first folding cardboard 36 swings downward and retracts, thus completing the folding and wrapping of the wrapping paper on the right side of the ice cream;

[0090] After the first turntable 311 rotates the ice cream 180°, the U-shaped clamping opening of the first die box 313 carrying the ice cream faces horizontally to the left and is horizontally opposite to the U-shaped clamping opening of one of the second die boxes 323 on the second turntable 321. The first push rod mechanism 314 on the left side of the first turntable 311 penetrates into the first die box 313 and pushes the ice cream to the left. The second push rod mechanism 324 on the right side of the second turntable 321 penetrates out of the second die box 323 and contacts the side of the ice cream in the first die box 313. During the process of the ice cream in the first die box 313 moving into the second die box 323, under the clamping action of the first push rod mechanism 314 and the second push rod mechanism 324, the second push rod mechanism 324 compacts the bonding area on the side of the ice cream, so that the adhesive provided in the bonding area bonds and fixes the two layers of wrapping paper;

[0091] During the process of the ice cream carrying the wrapping paper into the U-shaped clamping opening of the second die box 323, the folding plate 33 on the second die box 33 folds the wrapping paper at the left edge of the front end face of the ice cream. The wrapping paper at the upper and lower edges of the front end face of the ice cream is caught in the gap between the folding plate 33 and the second die box 323, so that the wrapping paper forms folds at the left edge end corners of the front end face of the ice cream. At the same time, the folding spring piece 34 folds the wrapping paper at the left edge of the rear end face of the ice cream. The wrapping paper at the upper and lower edges of the rear end face of the ice cream is caught in the gap between the folding spring piece 34 and the second die box 323, so that the wrapping paper forms folds at the left edge end corners of the rear end face of the ice cream. 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 323, under the action of the folding spring piece 34, the front end of the ice cream abuts against the folding plate 33. Since the length dimension of the ice cream varies in actual production, this can make the product wrapped in paper have a better and more regular effect;

[0092] When the ice cream carrying the wrapping paper completely enters the U-shaped clamping opening of the second die box 323 and the second turntable 321 rotates clockwise, when the ice cream rotates to the second folding cardboard 37, the drive motor drives the second folding cardboard 37 to flip. The second folding cardboard 37 folds the wrapping paper at the upper edge of the front end face of the ice cream. The ice cream rotates clockwise with the second turntable 321, and the fan-shaped folding cardboard 38 folds the wrapping paper at the lower edge of the front end face of the ice cream. The wrapping paper at the lower edge is folded and covers the wrapping paper folded at the upper edge, so that the wrapping paper forms an overlapping bonding area on the front end face of the ice cream. The second folding cardboard 37 flips and swings back to complete the folding and wrapping of the wrapping paper on the front end face of the ice cream. When the second die box 323 carries the ice cream and rotates past the pressing rollers 39, the multiple pressing rollers 39 press the bonding area on the front end face of the ice cream multiple times, so that the adhesive provided in the bonding area bonds and fixes the two layers of wrapping paper;

[0093] When the ice cream carrying the wrapping paper completely enters the U-shaped clamping opening of the second die box 323 and the second turntable 321 rotates clockwise, the positioning disk 302 rotates with the second turntable 321. The positioning disk 302 drives each mechanical clamping arm 303 to rotate. The Y-shaped push rod 3031 of the mechanical clamping arm 303 slides in the curve groove of the planar groove cam 301, and under the action of the planar groove cam 301, the Y-shaped push rod 3031 reciprocates radially in the radial chute to control the opening and closing of the two spring clamping arms 3032. When the ice cream enters the U-shaped clamping opening of the second die box 323, the wooden handle of the ice cream is caught in the folding spring piece 34. At this time, the two spring clamping arms 3032 of the mechanical clamping arm 303 corresponding to the second die box 323 are in an open state. When the second turntable 321 rotates, the two spring clamping arms 3032 gradually close and fold the wrapping paper at the upper and lower edges of the rear end face of the ice cream, sandwiching the wrapping paper on the wooden handle. Under the clamping action of the two spring clamping arms 3032, the adhesive provided on the wrapping paper bonds the wrapping paper to the wooden handle of the ice cream to complete the paper wrapping of the rear end face of the ice cream;

[0094] The second push rod mechanism 324 on the left side of the second turntable 321 penetrates into the second die box 323 and pushes the ice cream to the left, and the second push rod mechanism 324 pushes the ice cream onto the belt conveying surface of the second belt transmission mechanism 51; the speed at which the second push rod mechanism 324 pushes the ice cream is greater than the belt running speeds of the second belt transmission mechanism 51 and the third belt transmission mechanism 521, and the belt running speed of the second belt transmission mechanism 51 is slightly greater than the belt running speed of the third belt transmission mechanism 521. The ice cream is pushed onto the belt conveying surface of the second belt transmission mechanism 51, and the ice cream will move to the left along the belt baffle of the third belt transmission mechanism 521; at the corner of the third belt transmission mechanism 521, the belt baffle gradually separates from the ice cream, which will not affect the running state of the ice cream. The belt baffle is made of soft plastic and has a buffering effect on the ice cream;

[0095] The fourth belt transmission mechanism 531 is connected to the transmission end of the second belt transmission mechanism 51. The second belt transmission mechanism 51 conveys the ice cream wrapped in paper to the fourth belt transmission mechanism 531, and the fourth belt transmission mechanism 531 conveys the ice cream to the fifth belt transmission mechanism 532. Under the blocking and positioning action of the baffle on the fifth belt transmission mechanism 532, multiple ice creams are arranged and gathered on the belt conveying surface of the fifth belt transmission mechanism 532, waiting to be stacked; on the seventh belt transmission mechanism 534, the push plate rotates with the belt, and the push plate pushes the multiple ice creams detained by the baffle on the fifth belt transmission mechanism 532 onto the belt conveying surface of the sixth belt transmission mechanism 533 until multiple layers of ice creams are stacked on the belt conveying surface of the third belt transmission mechanism 521. The sixth belt transmission mechanism 533 conveys the stacked ice creams out, which is convenient for subsequent multi-layer and multi-piece ice cream integrated packaging and can improve production efficiency;

[0096] When cleaning and disinfecting the paper wrapping machine, the ice cream paper wrapping machine runs without load. The eighth conveyor belt, the first conveyor belt, the first rotating wheel mechanism 31 and the second rotating wheel mechanism 32 rotate at set speeds respectively, and the water pump 82 runs. The opening and closing of the electric valves at each spray head 83 are controlled as needed. The water pump 82 pumps the cleaning and disinfecting liquid in the water tank 81 to each spray head 83, and each spray head 83 sprays the cleaning and disinfecting liquid on the first conveyor belt, the eighth conveyor belt, the first rotating wheel mechanism 31 and the second rotating wheel mechanism 32, so as to achieve on-line cleaning and disinfection, with high cleaning efficiency and ensuring the hygiene and food safety and health of the food production line;

[0097] It should be noted here that in addition to wrapping ice cream, this paper wrapping machine can also be applied to the production and processing of square products such as ice cream. The square products include but are not limited to Sachima and rice flower candy. Although Sachima and rice flower candy do not include a wooden handle structure, it can be imagined that by referring to the origami structure on the front end surface of the ice cream and making slight improvements to the first rotating wheel mechanism 31 and the second rotating wheel mechanism 32, it is possible to wrap Sachima and rice flower candy without a wooden handle.
