Description

Technical Field

[0001] This invention belongs to the field of packaging equipment, specifically a bagging machine with good bagging effect. Background Technology

[0002] Currently, e-commerce sales models can bring in a large number of customers and significantly increase sales volume. This surge in sales volume has led to a demand for rapid packaging. In the packaging process, many products are placed in bags and then the bags are placed into boxes. This current process wastes a lot of time and significantly impacts packaging efficiency. Furthermore, the bags are prone to being misaligned, resulting in a decline in packaging aesthetics and quality. In addition, current bagging equipment cannot fully unfold the bags and has requirements regarding the shape of the containers to be bagged. Different shaped containers require different clamps, making the bagging process inconvenient.

[0003] For example, patent CN202022379803.6 uses an anti-static device to avoid the problem of plastic bags failing to be bagged due to static electricity, and also to avoid the problem of personnel injury caused by static electricity. However, it does not solve the problem of the plastic bag not being fully opened and adhered to the carton or other containers after bagging, which is also a problem that exists in the current mainstream bagging machines. Summary of the Invention

[0004] This invention provides a bagging machine with good bagging effect, capable of fully opening plastic bags and fitting them tightly to the bagging container, especially suitable for situations where the packaged contents are large and the plastic bags need to be fully opened. The technical problem to be solved is that current bagging machines cannot fully open plastic bags, leading to reduced packaging efficiency and a tendency to misalign the bags during packaging.

[0005] The technical solution adopted in this invention is patented: A bagging machine with good bagging effect includes a frame, a transport frame, a shearing frame, an opening frame, and a bag-supporting frame. The shearing frame is fixedly installed at the top of the frame, and the bag-supporting frame is installed directly below the shearing frame and directly below the opening frame. The transport frame is fixedly installed at the bottom of the frame. The shearing frame, bag-supporting frame, and opening frame are all fixedly connected to the frame. The opening frame is located directly below the shearing frame. The frame as a whole is a frame structure.

[0006] Furthermore, the transport frame includes a grid frame, a lifting frame, and conveying rollers. The transport frame is composed of multiple parallel conveying rollers. A grid frame is installed in the gap between adjacent conveying rollers. Adjacent grids of the grid frame are connected and fixed by the lifting frame. The top of the lifting frame extends outside the transport frame. A hydraulic cylinder is fixedly connected to the bottom of the lifting frame. Limiting strips are installed on the top of the grids at both ends of the grid frame. The lifting frame is located directly below the open frame.

[0007] Furthermore, the shearing frame includes a fixed plate, a rotating shaft, a chain, sprockets, and slide rails. The fixed plate is fixedly installed on the top of the frame, with one fixed plate on each side. The rotating shaft is rotatably connected between the two fixed plates. The shearing frame is a frame, with sprockets installed at the four corners of the lower part of the shearing frame. The four sprockets are fitted with chains on their exterior. A slide rail is installed on the lower inner surface of the shearing frame, directly below the chain. One slide rail is installed on each of the two opposite inner sidewalls, and the two ends of the slide rail are slidably connected to the oblique blade and the flat blade, respectively.

[0008] Furthermore, the opening frame includes a telescopic rod and a suction cup. The opening frame is located directly below the shearing frame and is fixedly connected to the shearing frame. The opening frame is a frame structure, and one suction cup is provided on each of the two opposite side walls of the shearing frame. The suction cups are connected to the opening frame via the telescopic rod.

[0009] Furthermore, the bag support frame includes a mounting plate, movable rods, a bag support plate, a telescopic column, and a rotating shaft. The bag support frame is located in the middle of the open frame. Movable rods are fixedly connected to two opposite side walls of the inner wall of the open frame. The movable rods are provided with sliding grooves. The bottom of the mounting plate is slidably connected to the two movable rods through the sliding grooves. The telescopic column is fixedly connected to the bottom center of the mounting plate. The end of the telescopic column away from the mounting plate is fixedly connected to the bag support plate. Air inlets are evenly arranged on the upper surface of the bag support plate, and exhaust ports are evenly arranged on the lower surface of the bag support plate. The air inlets and exhaust ports correspond one-to-one and are interconnected. The air inlets are connected to a blower.

[0010] Furthermore, the movable rod is provided with teeth parallel to the slide groove, which cooperate with the movable rod to form a rack. A rotating shaft is provided above the mounting plate, and movable gears are fixedly connected to both ends of the rotating shaft. The movable gears at both ends mesh with the teeth on both sides respectively. Both ends of the rotating shaft are connected to the bearing seat through the bearing seat, which is fixedly connected to the upper surface of the mounting plate. A driven bevel gear is fixedly connected to the end of the rotating shaft. A movable motor is fixedly connected to the upper surface of the mounting plate, and the output end of the movable motor is fixedly connected to the driving bevel gear. The driving bevel gear meshes with the driven bevel gear.

[0011] Furthermore, the flat blade and the oblique blade are opposite to each other, the end of the rotating shaft is connected to the rotating motor (3-10) through a coupling, the rotating motor (3-10) is fixedly installed on the side of the fixed plate opposite to the rotating shaft, the cutting motor is fixedly connected above the sprocket, and the cutting motor is fixedly connected to the frame of the shearing frame.

[0012] Furthermore, both the flat blade and the beveled blade are provided with connecting rods at their ends, and both the flat blade and the beveled blade are fixedly connected to the chain via the connecting rods. The connecting rods for the flat blade and the beveled blade are located at the ends on different sides.

[0013] Furthermore, the blade lengths at both ends of the oblique blade are different.

[0014] The above structure has the following beneficial effects: 1. By using a shearing frame with a rotating shaft and a combination of oblique and flat blades, the packaging bags are quickly cut and separated, overcoming the problem of discontinuous feeding in traditional feeding methods. This greatly improves the feeding speed of the packaging bags and ensures stable work efficiency.

[0015] 2. By using an opening frame to quickly open the packaging bag, it overcomes the limitations of existing packaging equipment that cannot quickly open the packaging bag, thus enabling rapid opening of the packaging bag, facilitating subsequent work, and improving work efficiency and quality.

[0016] 3. Because the bag support frame is used to quickly open the packaging bag, and the structure of the packaging box allows the packaging bag to fit the shape of the packaging box, it overcomes the problem that existing bagging machines cannot fit the shape of the packaging box well, thereby improving the bagging effect and quality.

[0019] like Figure 1-11 As shown: A bagging machine with good bagging effect includes a frame 1, a transport frame 2, a shearing frame 3, an opening frame 4, and a bag support frame 5. The shearing frame 3 is fixed to the top of the frame 1 with screws, and the bag support frame 5 is set directly below the shearing frame 3. The bag support frame 5 is located in the middle of the opening frame 4. The transport frame 2 is fixed to the bottom of the frame 1 with screws. The shearing frame 3, the bag support frame 5, and the opening frame 4 are all fixedly connected to the frame 1 with screws. The opening frame 4 is located directly below the shearing frame 3. The frame 1 is a frame structure. The frame structure can ensure strength while reducing machine weight and material consumption, and facilitates the adjustment of the bagging machine.

[0020] The transport frame 2 includes a grid frame 2-1, a lifting frame 2-2, and conveying rollers 2-5. The transport frame 2 is composed of multiple parallel conveying rollers 2-5, which facilitate and quickly transport the packaging boxes to the designated position. The grid frame 2-1 is installed in the gap between adjacent conveying rollers 2-5. The adjacent grids of the grid frame 2-1 are connected and fixed by the lifting frame 2-2. The top of the lifting frame 2-2 extends outside the transport frame 2, and the lifting frame 2-2 can rise from the gap between the conveying rollers 2-5 of the transport frame 2, thereby quickly lifting the packaging box to accommodate the packaging bag. The lifting frame 2-2 is fixedly connected to the bottom of the hydraulic cylinder 2-3 by screws. The hydraulic cylinder 2-3 can stably raise and lower the lifting frame 2-2. Limiting strips 2-4 are set on the top of the grids at both ends of the grid frame 2-1 to prevent the packaging box from falling. The lifting frame 2-2 is located directly below the open frame 4.

[0021] The shearing frame 3 includes a fixed plate 3-1, a rotating shaft 3-2, a chain 3-3, a sprocket 3-4, and a slide rail 3-6. The fixed plate 3-1 is fixedly installed on the top of the frame 1. There is one fixed plate 3-1 on each side. The rotating shaft 3-2 is rotatably connected between the two fixed plates 3-1. The shearing frame 3 is a frame. Sprockets 3-4 are installed at the four corners of the lower part of the shearing frame 3. The four sprockets 3-4 are externally connected to the chain 3-3. The sprockets 3-4 can drive the chain 3-3 to rotate. The slide rail 3-6 is installed on the lower inner surface of the shearing frame 3, directly below the chain 3-3. There is one slide rail 3-6 on each of the two opposite inner side walls. The two ends of the slide rail 3-6 are slidably connected to the oblique blade 3-7 and the flat blade 3-8 respectively. Both blades can slide along the slide rail 3-6, so that the cutting of the packaging bag can be completed quickly with the cooperation of the oblique blade 3-7 and the flat blade 3-8.

[0022] The opening frame 4 includes a telescopic rod 4-1 and suction cups 4-2. The opening frame 4 is located directly below the shearing frame 3 and is fixedly connected to the shearing frame 3 by screws. The opening frame 4 is a frame structure, with one suction cup on each of the two opposite side walls of the shearing frame 3. The frame of the opening frame 4 is a rectangular frame. Suction cups 4-2 are installed on the opposite sides of the two opening frames 4. The suction cups 4-2 quickly suck up the packaging bag from both sides with the help of suction, making it easy to open the packaging bag. The suction cups 4-2 are connected to the opening frame 4 through the telescopic rod 4-1. The extension and retraction of the telescopic rod 4-1 helps to quickly open the packaging bag with the help of the suction cups 4-2.

[0023] The bag support frame 5 includes a mounting plate 5-1, movable rods 5-2, a bag support plate 5-3, a telescopic column 5-6, and a rotating shaft 5-10. The bag support frame 5 is located in the middle of the opening frame 4. The two opposite side walls of the inner wall of the bag support frame 5 are fixedly connected to the movable rods 5-2 by screws. The movable rods 5-2 are provided with sliding grooves 5-8. The bottom of the mounting plate 5-1 is slidably connected to the two movable rods 5-2 through the sliding grooves 5-8. The mounting plate 5-1 can move along the movable rods 5-2, thereby controlling the position of the mounting plate 5-1. The bottom center of the mounting plate 5-1 is fixedly connected to the telescopic column 5-6 by screws. The end of the telescopic column 5-6 away from the mounting plate 5-1 is fixedly connected to the bag support plate 5-3 by screws. Air inlets 5-5 are evenly arranged on the upper surface of the bag support plate 5-3, and exhaust ports 5-4 are evenly arranged on the lower surface of the bag support plate 5-3. The air inlets 5-5 and exhaust ports 5-4 correspond one-to-one and are interconnected. The air inlet 5-5 is connected to a blower. The bag support plate 5-3 can enter the opening of the packaging bag with the help of the telescopic column 5-6. The gas discharged from the exhaust port 5-5 will quickly expand the packaging bag. With the help of the gas, the packaging bag can fit the structure of the packaging box, making the packaging work more convenient and improving the quality of bagging.

[0024] A toothed profile 5-7 parallel to the slide groove 5-8 is provided on the moving rod 5-2. The toothed profile 5-7 and the moving rod 5-2 form a rack. A rotating shaft 5-10 is provided above the mounting plate 5-1. Both ends of the rotating shaft 5-10 are keyed to moving gears 5-13. The moving gears 5-13 at both ends mesh with the toothed profile 5-7 on both sides. Both ends of the rotating shaft 5-10 are connected to the bearing seat 5-9 through bearings. The bearing seat 5-9 is connected to the upper surface of the mounting plate 5-1 by screws. The end of the rotating shaft 5-10 is keyed to the driven bevel gear 5-11. The upper surface of the mounting plate 5-1 is connected to the moving motor 5-14 by screws. The output end of the moving motor 5-14 is keyed to the driving bevel gear 5-12. The driving bevel gear 5-12 meshes with the driven bevel gear 5-11. Through the meshing of the gears, the moving motor 5-14 can drive the mounting plate 5-1 to move by rotating the rotating shaft 5-10 and the moving gear 5-13, thereby conveniently controlling the position of the bag-supporting plate 5-3. The mounting plate is moved away before the packaging bag enters the packaging box. After the packaging bag enters the packaging box and the opening is completed, the mounting plate 5-1 is moved so that the bag-supporting plate 5-3 is located directly above the packaging bag, so as to complete the bag-supporting work and ensure that the bagging work is carried out stably and smoothly.

[0025] The flat blade 3-8 and the oblique blade 3-7 face each other. The blade lengths of the two ends of the oblique blade 3-7 are different. The flat blade 3-8 and the oblique blade 3-7 form a scissor structure, which can effectively improve the cutting effect compared with the traditional two flat blades. The end of the rotating shaft 3-2 is connected to the rotating motor 3-10 through a coupling. The rotating motor 3-10 is fixedly set on the side of the fixed plate 3-1 opposite to the rotating shaft 3-2 by screws. The cutting motor 3-5 is fixedly connected above the sprocket 3-4 through a coupling. The cutting motor 3-5 is fixedly connected to the frame of the shearing frame 3 by screws.

[0026] Both the flat blade 3-8 and the oblique blade 3-7 are equipped with connecting rods 3-9 at their ends. Both the flat blade 3-8 and the oblique blade 3-7 are fixedly connected to the chain 3-3 through the connecting rods 3-9. The connecting rods 3-9 of the flat blade 3-8 and the oblique blade 3-7 are located at the ends on different sides. When the chain 3-3 moves, the two chains 3-3 on both sides move in opposite directions. At this time, with the help of the connecting rods 3-9, the flat blade 3-8 and the oblique blade 3-7 can move towards each other, thereby quickly completing the cutting of the packaging bag. Reversing the chain 3-3 can separate the two blades.

[0027] How this example works: During use, the entire roll of packaging bags is placed on the rotating shaft 3-2 and secured. As the shaft rotates, the packaging bags are quickly fed into the workstation. Simultaneously, the transport frame 2 transports the packaging box directly beneath the packaging bags. The lifting frame 2-2 then lifts the packaging box. At this point, the rotating motor 3-10 drives the chain to rotate, feeding the packaging bags into the shearing frame 3. Simultaneously, the telescopic rod 4-1 drives the suction cup 4-2 to hold the packaging bags. Then, the cutting motor 3-5 is started, driving the chain 3-3 to move, causing the flat blade 3-8 and the oblique blade 3-7 to move towards each other, completing the cutting of the packaging bags. After the cutting is complete, the telescopic rod 4-1 drives the suction cup 4-2 to reset. As the suction cup resets, the opening of the packaging bag is opened. The bottom of the bag falls into the packaging box. At this time, the moving motor 5-14, with the help of the rotating shaft 5-10 and the moving gear 5-13, drives the mounting plate 5-1 to the top of the packaging bag. The telescopic column 5-6 then lowers the bag-supporting plate 5-3 into the opening of the packaging bag. The gas discharged through the exhaust port 5-4 expands the packaging bag. Because of the external packaging box, it can ensure that the shape of the packaging bag is the same as that of the packaging box, and can fit tightly. Compared with traditional bagging equipment, the bag-supporting and fitting by gas greatly improves the bag-supporting effect. At the same time, it can also achieve good fitting for packaging boxes of different shapes, which facilitates subsequent packaging work. Moreover, the bag-supporting effect is better with the help of gas, and the packaging bag can be fully unfolded, improving the quality of bagging.
