Description

Technical Field

[0001] This utility model relates to the field of yogurt packaging equipment technology, specifically to a milk carton packaging roll-up machine. Background Technology

[0002] In yogurt production enterprises, yogurt packaging is classified in different ways. Our factory uses milk carton-shaped hard paper packaging. This type of packaging paper is purchased and customized according to demand and is in the form of a roll. When using it, operators need to feed the packaging paper into the packaging machine for the machine to produce packaging.

[0003] To ensure a longer lifespan for each roll of packaging paper, the customized rolls are quite heavy, making loading difficult for workers and requiring the use of factory handling vehicles with lifting capabilities. However, these vehicles are not compatible with the packaging machines, necessitating manual alignment and installation of the paper rolls at the machine's feed inlet. Furthermore, traditional handling equipment cannot adjust to the roll length when the factory changes its paper roll specifications. Workers must also disassemble and remove the rolls after use while operating the equipment; these steps need to be simplified to improve the efficiency of paper roll replacement. Utility Model Content

Detailed Implementation

[0024] like Figure 1-5 As shown, a milk carton packaging roll-up machine is described. This equipment relies on a frame 1 to support and move a packaging paper roll 22. The bottom of the frame 1 has wheels 2 at both ends; a lifting frame 3 slides between the frames 1; a movable hook groove 1.1 is provided on the inner side of the frame 1; limit wheels 3.1 are rotatably provided on both sides of the lifting frame 3; the limit wheels 3.1 move up and down along the movable hook groove 1.1. A foot-operated hydraulic cylinder 11 is fixed to the inner side of the frame 1 at the back of the lifting frame 3; a T-shaped connector 12 is fixed to the telescopic end of the foot-operated hydraulic cylinder 11; sprockets 13 are movably provided at both ends of the T-shaped connector 12; a fixing plate 15 is installed at the bottom of the frame 1; the fixing plate 15 is fixed to one end of a chain 14; the other end of the chain 14 is fixed to the lifting frame 3; the foot-operated hydraulic cylinder 11 drives the sprockets 13 up and down through lifting and simultaneously engages with the chain 14 for transmission. To ensure the supporting strength of the frame 1, the frame 1 has an overall L-shaped frame structure; a reinforcing rib 16 is fixed to the top of the back of the frame 1. A handrail 17 is fixed in the middle of the back of the frame 1, allowing operators to stand on the back of the frame 1 to move the equipment. A protective backplate 21 is installed on the inside of the handrail 17 on the frame 1, which can isolate the sprocket 13 and chain 14, prevent operators from coming into contact with the sprocket 13 and chain 14, and reduce the risk of equipment operation.

[0025] like Figure 3-5As shown, a connecting plate 4 is fixed to the front of the lifting frame 3; two support plates 5 are movably nested on the front of the connecting plate 4, and the support plates 5 can be adjusted laterally along the axis of the connecting plate 4; a slide groove 7 is fixed below the movably nested position of the connecting plate 4; a partition plate 8 is fixed in the middle of the slide groove 7; a first lead screw 9 and a second lead screw 10 are movably provided on both sides of the partition plate 8; a limiting slider 6 is passed through the first lead screw 9 and the second lead screw 10 respectively, and the limiting slider 6 moves along the slide groove. Each limiting slider 6 is clamped and fixed to the end of a different support plate 5; a first adjusting plate 19 and a second adjusting plate 20 are fixed to the outer end of the first lead screw 9 and the second lead screw 10 respectively, for the operator to adjust the distance between the support plates 5 through the first adjusting plate 19 and the second adjusting plate 20 to accommodate the width of the packaging paper roll 22. The end of the support plate 5 is provided with a groove 5.1 that mates with the shaft; the packaging paper roll 22 is placed between the grooves 5.1 of the two support plates 5. As shown in the figure, side plates 23 are threaded onto both ends of the shaft. The protrusions on the side plates 23 are the mounting support positions inside the packaging machine, while the protruding parts at both ends of the shaft are the positions for mating with the slots 5.1. The two positions are staggered and do not interfere with each other. Furthermore, a shaft-holding plate 18 is fixed to one side of the frame 1; the surface of the shaft-holding plate 18 has a groove 18.1 that mates with the side plates 23 that hold the packaging paper roll 22, and a notch 18.2 for the shaft to enter is opened in the groove 18. Unless otherwise described, the fixing methods mentioned above are all achieved by welding or threaded fastening using common techniques used by industry professionals.

[0026] The working principle is as follows:

[0027] The packaging paper roll 22 is placed upright in the storage area. The operator moves the milk carton packaging roll-up machine to a designated position, positioning the packaging paper roll 22 between the support plates 5. The foot-operated hydraulic cylinder 11 is used to raise the support plates 5, aligning the slots 5.1 of the support plates 5 with the shaft of the packaging paper roll 22. The operator confirms that the spacing between the support plates 5 is appropriate, as the spacing is controlled by the first adjusting plate 19 and the second adjusting plate 20. After confirmation, the machine is raised and lowered a second time until the shaft of the packaging paper roll 22 enters the slot 5.1 and is lifted off the ground. The operator then moves the machine to the packaging machine. The door panel of the packaging machine's roll-up position is opened, and the machine is pushed in. The support plates 5 and the bottom of the frame 1 of the machine enter the packaging machine, while other parts of the machine do not. After the support components of the packaging machine clamp the packaging paper roll 22, the support plates 5 of the machine descend and disengage from the shaft of the packaging paper roll 22. The machine then detaches from the packaging machine, completing the roll-up process.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
