Technical Field

[0001] The utility model relates to the field of food processing equipment with bowl-shaped packaging, and specifically to an automatic folding device for the pull tabs of sealed easy-open lids of packaging bowls. Background Art

[0002] Sealed food in bowl-shaped packaging, such as sealed easy-open lid packaging PP plastic bowls, sealed easy-open lid packaging aluminum bowls, small gold bowls, etc., is a new type of environmentally friendly food packaging. The materials are environmentally friendly, healthy and safe. The products are covered with aluminum film or tin film, with excellent barrier properties: having excellent oxygen, water vapor and light barrier capabilities, good sealing performance, strong heat preservation and freshness preservation capabilities, high chemical stability: the aluminum film and tin film are not easy to react chemically with most substances, ensuring that the packaged contents are not contaminated. Good heat-sealing performance: it is easy to achieve tight heat-sealing with the bowl mouth, ensuring the reliability of the seal. The freshness preservation effect is remarkable: it can effectively inhibit the growth of microorganisms, extend the shelf life of food, and at the same time avoid spilling or being contaminated during food storage and transportation. It has high recyclability and regenerability, and can be recycled; there is a pull tab for easy opening on the sealed easy-open lid of the packaging bowl, and labels introducing product information are usually pasted on the sealed easy-open lids of the aluminum film and tin film. In traditional production processes, the pull tabs are usually folded manually. After folding the pull tabs outside the bowl, labeling is then carried out by a labeling machine or manually. The labor cost is relatively high, and the production efficiency is low. In view of this, this case is thus generated. Content of the Utility Model

[0028] The following further describes the present utility model through specific embodiments.

[0029] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model is further described below in conjunction with specific embodiments.

[0030] As Figures 1-4 shown, the automatic folding easy-open lid handle device for the sealed easy-open lid packaging bowl of the present utility model sequentially includes, from the feeding end to the discharging end:

[0031] A belt clamping and material distributing mechanism 1, which is provided with a clamping and material distributing channel 11 for distributing materials at a fixed interval;

[0032] A belt speed difference steering mechanism 2, which is provided with a differential steering channel 21 for steering materials;

[0033] A handle folding mechanism 3, which is provided with a handle folding channel 31 for folding the handle of the material;

[0034] As Figure 3 shown, the clamping and material distributing channel 11, the differential steering channel 21, and the handle folding channel 31 are sequentially connected, and a flat conveyor 4 is provided below. The automatic folding easy-open lid handle device for the sealed easy-open lid packaging bowl provided by the present utility model is applicable to sealed food in bowl-shaped packages, such as sealed easy-open lid packaging PP plastic bowls, sealed easy-open lid packaging aluminum bowls, small gold bowls, etc. As Figure 6 shown, its bowl rim has a circular contour, and the sealed easy-open lid 100 is provided with a handle 200 for easy opening. The packaging bowl is in contact with the belt surface of the conveyor belt of each mechanism during transportation for transportation; the double belts of the belt clamping and material distributing mechanism 1 are used to distribute the sealed easy-open lid packaging bowls at a fixed interval, the angle of the handle is positioned through visual recognition, and the double belts of the belt speed difference steering mechanism 2 are used for differential steering so that the handles are in the same direction. Finally, the high-speed rotating brush 341 on the handle folding mechanism 3 folds the handle 200 from the inside of the bowl to the outside of the bowl, which is convenient for the labeling machine in the subsequent process to label. The whole process adopts automated continuous operation, replacing the traditional manual folding process, reducing the labor cost, and greatly improving the production efficiency.

[0035] The belt clamping and material separating mechanism 1 includes a left clamping conveyor belt 12 and a right clamping conveyor belt 13, and a clamping and material separating channel 11 is formed between the left clamping conveyor belt 12 and the right clamping conveyor belt 13. The packaging bowl enters the clamping and material separating channel 11. The left and right belts contact the rim contour of the packaging bowl and drive it forward. The conveying rhythm is controlled by the conveying of the double belts, so that the packaging bowl enters the differential steering channel 21 of the subsequent belt speed difference steering mechanism 2 at a fixed interval, realizing continuous production.

[0036] The belt speed difference steering mechanism 2 includes a left steering conveyor belt 22, a right steering conveyor belt 23 and a visual recognition device 24. A differential steering channel 21 is formed between the left steering conveyor belt 22 and the right steering conveyor belt 23, and the visual recognition device 24 is suspended above the differential steering channel 21. The visual recognition device 24 identifies the position of the handle by taking pictures, calculates the angle required to rotate the handle to the opposite direction of the belt conveying, as well as the required speed difference of the servo motor, and transmits the speed difference data to the servo controller to control the speed difference of the double belts to steer the packaging bowl while conveying. The steering process does not stop, and continuous production can be realized, which is different from traditional manual production or intermittent production of existing equipment, and can greatly improve production efficiency.

[0037] The visual recognition device 24 includes a camera and a controller. The camera is responsible for collecting graphic signals and transmitting the signals to the controller for analysis. The software of the controller identifies the position of the handle according to the graphic signals, calculates the angle required to rotate the handle to the customized positioning, and then calculates the respective traveling speeds of the left steering conveyor belt 22 and the right steering conveyor belt 23, and transmits the signals to the left steering conveyor belt 22 and the right steering conveyor belt 23 to realize differential speed and steering control. The visual recognition device 24 is suspended above the differential steering channel 21 through a visually recognizable support frame 25 with adjustable position. The visually recognizable support frame 25 includes a support base, a longitudinal L-shaped adjustment member and a transverse positioning seat. The longitudinal L-shaped adjustment member is provided with longitudinal strip holes and transverse strip holes. The support base is connected to the longitudinal L-shaped adjustment member through a connecting member passing through the longitudinal strip holes, and the transverse positioning seat is connected to the longitudinal L-shaped adjustment member through a connecting member passing through the transverse strip holes. By adjusting the positions in the longitudinal strip holes and the transverse strip holes, the horizontal and vertical positions of the visual recognition device 24 are positioned to adapt to packaging bowls with different diameters and heights and maintain the best height for visual recognition.

[0038] The folding handle mechanism 3 includes a left folding handle conveyor belt 32, a right folding handle conveyor belt 33, and a handle flipping device 34. A folding handle channel 31 is formed between the left folding handle conveyor belt 32 and the right folding handle conveyor belt 33. The handle flipping device 34 includes a flipping member for driving the handle to flip and a flipping drive unit for driving the flipping member to rotate. The flipping member is located within the folding handle channel 31. The rotating flipping member contacts the handle and drives it to fold outwards.

[0039] There is one or more handle flipping devices 34. One or more brushes 341 are provided on the flipping member. The flipping drive unit is a rotating motor 342, and the rotating motor 342 drives the brush 341 to rotate. When multiple handle flipping devices 34 work in cooperation, the success rate of handle folding can be further improved. The handle flipping device 34 further includes an adjustable-height handle flipping base 343. A longitudinal adjustment slider is provided on the handle flipping base 343, and the rotating motor 342 is fixed on the longitudinal adjustment slider. The height of the longitudinal adjustment slider on the handle flipping base 343 is adjustable. The bristles on the brush 341 have good flexibility. As a flipping member, it can adapt to packaging bowls and handles of different shapes and can work stably and efficiently in cooperation with a high-speed rotating motor, ensuring that the handle is folded in the folding handle channel 31.

[0040] The left clamping conveyor belt 12, the right clamping conveyor belt 13, the left turning conveyor belt 22, the right turning conveyor belt 23, the left folding handle conveyor belt 32, and the right folding handle conveyor belt 33 are driven by servo motors. The servo motors can accurately control the conveying speeds of each conveyor belt, so as to achieve synchronous or differential travel.

[0041] The left clamping conveyor belt 12, the right clamping conveyor belt 13, the left turning conveyor belt 22, the right turning conveyor belt 23, the left folding handle conveyor belt 32, and the right folding handle conveyor belt 33 are all arranged on the base of the lead screw adjustment mechanism 5. The distance between the opposite conveyor belts can be adjusted through the lead screw adjustment mechanism 5, and then the widths of the clamping and feeding channel 11, the differential turning channel 21, and the folding handle channel 31 can be adjusted. Since there are different size specifications for the packaging bowls, with different diameters and heights, the distance between the channels can be adjusted through the lead screw adjustment mechanism 5 to adapt to packaging bowls of different diameters. The brush 341 itself has flexibility, and combined with the adjustable height of the brush 341, it can therefore adapt to products within different height ranges. The lead screw adjustment mechanism 5 is equipped with a locking positioner to ensure that the distance remains fixed after positioning.

[0042] As Figure 5 shown, the automatic folding easy-open lid handle device for the sealed easy-open lid packaging bowl further includes a housing to achieve closed production, and a maintenance door is provided on the side of the housing.

[0043] A method for automatically folding the pull tab, which is produced by using the above-mentioned automatic folding equipment for the pull tab of the sealed easy-open lid packaging bowl, includes the following steps:

[0044] Step a: The sealed easy-open lid packaging bowl is conveyed into the clamping and feeding channel 11 of the belt clamping and feeding mechanism 1 through the flat conveyor 4. The left clamping conveyor belt 12 and the right clamping conveyor belt 13 moving at the same speed clamp the outer circular contour of the packaging bowl and convey the packaging bowl to the differential turning channel 21 at a fixed speed and fixed interval.

[0045] Step b: Driven by the left clamping conveyor belt 12 and the right clamping conveyor belt 13, the packaging bowl enters the differential turning channel 21. When passing under the visual recognition device 24, the visual recognition device 24 locates the current angle of the pull tab of the packaging bowl and transmits the data of the required turning distance and direction to the differential servo. The differential servo controls the left clamping conveyor belt 12 and the right clamping conveyor belt 13 to form a speed difference, thereby driving the packaging bowl to turn, so that the pull tabs are in the same direction. After visual recognition positioning and differential turning by the belt differential turning mechanism 2, all the pull tabs of the packaging bowls entering the pull tab folding channel 31 will be in the opposite direction of the conveying direction, which is convenient for the subsequent pull tab folding mechanism 3 to flip the pull tabs.

[0046] Step c: The packaging bowl enters the pull tab folding channel 31. The left pull tab conveying conveyor belt 32 and the right pull tab conveying conveyor belt 33 maintain the same speed, so that the pull tabs of the packaging bowl remain in the same direction during transportation. Driven by the high-speed rotating brush 341, the original pull tab inside the bowl is turned outwards to the outside of the bowl. The rotating direction of the brush 341 is towards the incoming material direction, and the soft bristles lift the pull tab and turn it outwards. After the pull tab is turned outwards to the outside of the bowl, it is convenient for the labeling machine to label the sealed easy-open lid of the packaging bowl in the subsequent process.

[0047] The above are only several specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive modification made to the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
