Description

Technical Field

[0001] The present invention relates to the technical field of mooncake packaging equipment, in particular to a pillow-type automatic mooncake packaging machine. Background Art

[0002] Mooncakes are categorized into two main types: traditional and non-traditional. Traditional mooncakes are traditional Chinese mooncakes, classified by origin, sales volume, and characteristics into four main types: Cantonese, Beijing, Suzhou, and Chaozhou. With growing consumer demand, mooncake varieties are becoming increasingly diverse. After processing, mooncakes need to be packaged.

[0003] Most existing pillow-type automatic packaging machines use conveyor belts to transport mooncakes until they are placed into packaging bags, where they are then sealed and cut. During this process, because the mooncake crust is made of flour, milk powder, and syrup, the crust's dryness is easily affected during transport. The crust tends to stick to the conveyor belt, causing it to become stuck when docked with the bag. Furthermore, food debris and powder from the crust can easily become lodged on the conveyor belt, affecting its cleanliness. Summary of the Invention

[0004] In order to solve the above problems, the purpose of this application is to provide a pillow-type mooncake automatic packaging machine.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a pillow-type mooncake automatic packaging machine, comprising a conveying structure and a positioning structure, a film wrapping structure, a transverse sealing structure and a frame located behind the conveying structure. The mooncakes are transferred by the conveying structure to the surface of the positioning structure and connected to the packaging, and then are transferred to the inner side of the film wrapping structure and the transverse sealing structure for sealing operations.

[0006] The conveying structure includes a conveyor belt that can convey moon cakes, a guide frame arranged on both sides of the conveyor belt, and a plurality of push rods located above the conveyor belt. Both ends of the push rods are threadedly connected to extension rods, and the extension rods pass through the guide frame and extend to its outside. A movable conveyor timing belt is provided on the outside of the guide frame. The conveyor timing belt can drive the extension rods and push rods to rotate along their motion trajectory and contact the surface of the conveyor belt.

[0007] The surface of the transmission timing belt is provided with a docking protrusion that can accommodate the extension rod to pass through, and the inner side of the transmission timing belt is provided with a pair of synchronous wheels that are compatible with it. The front end of the synchronous wheel is installed on the outer side of the guide frame through the frame, and a servo motor that is compatible with the synchronous wheel is installed on the surface of the frame.

[0008] Furthermore, the alignment structure includes a limit seat connected to the conveyor belt, a support frame is installed below the limit seat, and the support frame is installed on the inner side of the frame. The packaging bag can be transferred from the inner side of the gap between the conveyor belt and the limit seat to the inner side of the limit seat.

[0009] A guide roller is provided below the limit seat, the guide roller is installed on the inner side of the frame, and a servo motor 2 adapted to the guide roller is installed on the surface of the frame.

[0010] Furthermore, a winding roller capable of receiving and storing packages is provided behind and below the guide roller, and a chassis capable of controlling the rotation of the winding roller is installed on the surface of the frame.

[0011] Furthermore, the film-wrapping structure includes multiple groups of heat-sealing plates arranged behind the limit seat, and the tops of the heat-sealing plates are each equipped with a rotating wheel. The same positioning frame is installed above the multiple rotating wheels, and the upper surface of the positioning frame is equipped with multiple servo motors three that can drive the rotating wheels and the heat-sealing plates to rotate. Positioning arms are installed on both sides of the positioning frame, and the positioning arms are installed on the inner side of the frame.

[0012] Furthermore, a conveyor belt 2 is installed on the inner side of the positioning arm 1, and the conveyor belt 2 is located directly behind the limiting seat.

[0013] Furthermore, the transverse sealing structure includes a liftable transverse sealing block, which can be heated to perform a heat-sealing operation on the mooncake outer packaging. A cutting piece is embedded on the surface of the transverse sealing block for cutting the mooncake outer packaging to form a separate bag body.

[0014] A linkage frame is installed on the top of the horizontal sealing block, and positioning arms 2 are installed on both sides of the horizontal sealing block. A cylinder that can drive its lifting and lowering movement is installed above the linkage frame. The cylinder is installed on the crossbeam surface of positioning arm 2, and positioning arm 2 is installed on the inner side of the frame.

[0015] Furthermore, a conveyor belt three is installed on the inner side of the positioning arm two, and the conveyor belt three is located directly behind the transverse sealing block, and is used to transfer the transversely sealed and cut moon cakes.

[0016] Furthermore, a docking die base adapted to the transverse sealing block is installed on the inner side of the second positioning arm, and the docking die base is located on the front side of the third conveyor belt.

[0017] In summary, the technical effects and advantages of the present invention are as follows:

[0029] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] Example: Reference Figure 1 、 Figure 2 The pillow-type mooncake automatic packaging machine shown includes a conveying structure 1, a positioning structure 2, a film wrapping structure 3 and a transverse sealing structure 4 arranged in sequence behind the conveying structure 1. The mooncakes are transferred by the conveying structure 1 to the surface of the positioning structure 2 where they are connected to the packaging, and then are transferred to the inner side of the film wrapping structure 3 and the transverse sealing structure 4 for sealing operations.

[0031] like Figure 3 、 Figure 4 As shown, the conveying structure 1 includes a conveyor belt 11 for conveying moon cakes, a guide frame 12 arranged on both sides of the conveyor belt 11, and a plurality of push rods 13 located above the conveyor belt 11. Both ends of the push rods 13 are threadedly connected with extension rods 14, which pass through the guide frame 12 and extend to the outside thereof. A movable conveyor timing belt 15 is provided on the outside of the guide frame 12. The conveyor timing belt 15 can drive the extension rods 14 and the push rods 13 to rotate along their motion trajectory and contact the surface of the conveyor belt 11.

[0032] The surface of the transmission timing belt 15 is provided with a docking protrusion 16 that can accommodate the extension rod 14 to pass through, and the inner side of the transmission timing belt 15 is provided with a pair of synchronous wheels 17 that are compatible with it. The front end of the synchronous wheel 17 is installed on the outer side of the guide frame 12 through the frame, and a servo motor 18 that is compatible with the synchronous wheel 17 is installed on the surface of the frame.

[0033] During the mooncake packaging process, the PLC controller controls the operation of servo motor 18, which in turn controls the rotation of one of a pair of synchronous wheels 17 located on the same side, thereby pulling the conveyor belt 15 in a crawler-like motion. During this process, the extension rod 14 and push rod 13 continuously pass over the mooncakes near the alignment structure 2, move behind them, and push them into the surface of the alignment structure 2. This process effectively prevents the mooncake crust from sticking to the surface of conveyor belt 11, improving the accuracy of the mooncake and packaging bag connection.

[0034] When the mooncake is pushed into the surface of the alignment structure 2 and contacts the packaging bag, the push rod 13 located behind it can contact the surface of the conveyor belt 11 as the conveyor timing belt 15 moves, cleaning the food debris adhering to the surface of the conveyor belt 11, thereby ensuring the cleanliness of the conveyor belt 11. As the conveyor timing belt 15 continues to operate, the push rod 13 can move repeatedly to implement continuous cleaning operations, effectively preventing food debris from adhering to the surface of the conveyor belt 11 to form stains, thereby reducing the workload of manual cleaning.

[0035] like Figure 5 、 Figure 6 As shown, the alignment structure 2 includes a limit seat 21 connected to the conveyor belt 11, and a support frame 22 is installed below the limit seat 21. The support frame 22 is installed on the inner side of the frame. The packaging bag can be transferred from the inner side of the gap between the conveyor belt 11 and the limit seat 21 to the inner side of the limit seat 21.

[0036] A guide roller 23 is located below the stopper 21 and is mounted on the inside of the frame. A servo motor 24, compatible with the guide roller 23, is mounted on the surface of the frame. During the mooncake packaging process, the servo motor 24 controls the operation of the guide roller 23, ensuring the accuracy of the packaging bag's position as it is transferred from the gap between the conveyor belt 11 and the stopper 21 to the inside of the stopper 21, thereby reducing friction between the packaging bag and the edge of the stopper 21.

[0037] A reel 25 for receiving the package is located behind and below the guide roller 23. A housing 26 is mounted on the frame to control the rotation of the reel 25. The housing 26 controls the rotation of the reel 25, smoothly transferring the reeled package bag to the surface of the retaining seat 21, thereby connecting the package bag to the mooncake.

[0038] like Figure 5 、 Figure 6As shown, the film-wrapping structure 3 includes multiple sets of heat-sealing plates 31 positioned behind the retaining seat 21. Rotating wheels 32 are mounted on top of each heat-sealing plate 31. A common positioning frame 33 is mounted above the multiple rotating wheels 32. Mounted on the upper surface of the positioning frame 33 are multiple servo motors 34 that drive the rotating wheels 32 and heat-sealing plates 31. When the mooncakes and packaging bags are transferred directly below the film-wrapping structure 3, the PLC controller controls the servo motors 34, rotating the rotating wheels 32 and heat-sealing plates 31, driving the sides of the package to seal and close, ensuring the packaging bag is precisely wrapped around the surface of the mooncake.

[0039] Positioning arms 35 are mounted on either side of the positioning frame 33, located inside the frame. Conveyor belt 36 is mounted inside positioning arms 35, located directly behind the stopper 21. Conveyor belt 36 smoothly transports the mooncake packaging bags and their contents to the bottom of the transverse sealing structure 4.

[0040] like Figure 6 、 Figure 7 As shown, the transverse sealing structure 4 includes a liftable transverse sealing block 41. A linkage frame 43 is mounted on top of the block 41, and two positioning arms 45 are mounted on either side of the block 41. A cylinder 44, which drives the linkage frame 43 upward and downward, is mounted above the linkage frame 43. Cylinder 44 is attached to the crossbeam surface of the second positioning arm 45, which is mounted inside the frame. When the mooncakes and packaging bags are transported directly below the transverse sealing structure 4, the PLC controller controls the operation of the cylinder 44, which in turn drives the linkage frame 43, the transverse sealing block 41, and the cutting blade 42 to descend synchronously, heat-sealing the mooncake packaging. A cutting blade 42 is embedded in the surface of the transverse sealing block 41 to sever the mooncake packaging into individual bags.

[0041] like Figure 5 As shown, a third conveyor belt 46 is mounted on the inner side of the second positioning arm 45. This conveyor belt 46 is located directly behind the transverse sealing block 41 and is used to transport the transversely sealed and cut mooncakes. A docking die holder 47, which mates with the transverse sealing block 41, is mounted on the inner side of the second positioning arm 45. This docking die holder 47 is located in front of the third conveyor belt 46. When the transverse sealing block 41 descends, it presses the packaging bag against the surface of the docking die holder 47, sealing the bag and forming an indentation, ensuring a tight connection between the bags.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
