Description

Technical Field

[0001] The present invention relates to the field of cigarette manufacturing, and particularly to a swing loader for packing cut tobacco into boxes. Background Art

[0002] At present, the external transportation of cut tobacco in the tobacco industry still relies on traditional simple methods, using manual packing and sealing of boxes. Since cut tobacco is relatively fluffy in a free state, it occupies a large volume and has a light weight when packed in boxes, resulting in relatively high packing and transportation costs. During the stage of quantitatively packing boxes with cut tobacco, when the box is filled with the specified weight and exits the packing station, the height of the cut tobacco packed in the box greatly exceeds the upper surface of the box, and manual compaction is required. During the compaction process, a large amount of breakage is easily generated, which has a great impact on the quality of cut tobacco. At the same time, the box filled with cut tobacco is transported backward under the action of a roller conveyor. When it stops at the sealing and packing station, the cut tobacco is likely to fall out of the box under the action of inertia, and then float onto the equipment and the ground, which not only affects the production site environment but also greatly wastes cut tobacco raw materials. Summary of the Invention

[0003] In view of the above, the present invention aims to provide a swing loader for packing cut tobacco into boxes to solve the aforementioned technical problems.

[0004] The technical solution adopted by the present invention is as follows:

Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0034] An embodiment of a swing loader for packing cut tobacco is proposed by the present invention. Specifically, as Figures 1 to 6 shown, which includes:

[0035] A frame 1, a roller 2, a lifting cylinder 3, a swing cylinder 4, a lifting link 5, a swing push rod 6, a swing link 7, and two top box blocks 8; wherein, the lifting link 5 has an asymmetric cross-shaped structure, the swing link 7 includes a swing arm 71 having a preset first obtuse angle (pointing to the middle part in the figure), the swing push rod 6 includes a vertical plate 65 and a horizontal plate 63 fixedly connected to the vertical plate 65 and having a preset second obtuse angle, the horizontal plate 63 is located below the swing arm 71 and is used to push the swing arm 71 to move; preferably, the first obtuse angle is greater than the second obtuse angle.

[0036] The frame 1 is installed below the blanking hopper of the cut tobacco conveying belt;

[0037] A plurality of the rollers 2 are installed on the cross beam of the frame 1 and are arranged parallel to each other; further, the upper surface of the roller 2 is higher than the upper surface of the frame 1, which is convenient for the conveyance of the carton on the surface of the roller.

[0038] The first end 51 of the lifting link 5 is rotatably connected to the cross beam of the frame 1 (this rotational connection can be achieved through a first spherical plain bearing 9 fixed on the cross beam of the frame 1. Specifically, the first spherical plain bearing 9 is two external thread spherical plain bearings, the screw of the first spherical plain bearing 9 passes through the frame 1 and is fixed by a nut, and the first end 51 is movably connected to the spherical eye holes of the two external thread spherical plain bearings respectively);

[0039] The swing cylinder 4 is installed on the second end 52 of the lifting link 5 (when implementing, it can be considered that the tail end of the swing cylinder 4 is movably installed on the second end 52 of the lifting link 5 through a first double-ear cylinder seat 10 ( Figure 1 There is occlusion in the figure, for reference, see Figure 6 ), the cylinder rod of the swing cylinder 4 is rotatably connected to the lower part 62 of the vertical plate 65 (this rotational connection can be achieved through a second spherical plain bearing 11. Specifically, the second spherical plain bearing 11 can adopt an internal thread spherical plain bearing, and the lower part 62 of the swing push rod 6 is movably connected to the spherical eye hole of the second spherical plain bearing 11);

[0040] The third end 53 of the lifting link 5 is rotatably connected to the middle of the swing arm 71 through a hole 61 in the upper part of the vertical plate 65 (a common bearing can be used here);

[0041] The lifting cylinder 3 is installed on the frame 1 (when implemented, it can be considered to be movably installed on a crossbar in the middle of the frame 1 through a second double-ear cylinder seat 13 at the tail end of the lifting cylinder 3). The cylinder rod of the lifting cylinder 3 is rotatably connected to the fourth end 54 of the lifting link 5 (this rotational connection can be achieved through a third spherical plain bearing 12. Specifically, the third spherical plain bearing 12 can be an internal thread spherical plain bearing, and the fish-eye hole of the third spherical plain bearing 12 is movably connected to the fourth end 54 of the lifting link 5). The fourth end 54 is opposite to the second end 52;

[0042] The top box blocks 8 are respectively fixed at both ends of the swing arm 71, and a gap for the top box blocks 8 to lift through is provided between the rollers 2 corresponding to the positions of the top box blocks 8, so that the top box blocks 8 drive the cartons on the rollers 2 to swing;

[0043] The two top box blocks 8 and each of the rollers 2 between them form a carton loading station.

[0044] Further, threaded holes 64 are respectively opened at both ends of the horizontal plate 63. The threaded holes 64 are used to connect rubber top blocks 14 with screw rods. The rubber top blocks 14 are used to push the swing arm 71 to swing.

[0045] Finally, it can also be supplemented that, in order to ensure more reliability during the process of swinging the carton, a supporting baffle 81 is provided at the top box block 8. The supporting baffle 81 cooperates with both sides of the bottom of the carton to play a role of reliably supporting and preventing the carton from slipping out.

[0046] Based on the above various embodiments, the following working process is provided for reference: Before the cardboard box reaches the packing station, the piston rod of the lifting cylinder 3 can be in the retracted state, and the box-lifting block 8 is located below the roller 2; when the cardboard box is placed or conveyed to the packing position (the cardboard box can be sent to the packing station by the roller), the original machine equipment starts to pour tobacco shreds into the cardboard box. At this time, the two cylinders respectively perform the pushing, swinging and lifting actions, that is, the solenoid valve controls the piston rod of the lifting cylinder 3 to extend, driving the multiple ends of the lifting link 5 to rise, so that the swing arm 71 installed on the third end 53 drives the box-lifting blocks 8 on both sides to rise as a whole, lifting the cardboard box; the solenoid valve controls the piston rod of the swing cylinder 4 to extend, driving the swing push rod 6 to rotate counterclockwise, and one side of the cross plate 63 lifts the same side of the swing arm 71, and the cigarette box is lifted by the corresponding box-lifting block. Correspondingly, the solenoid valve then controls the piston rod of the swing cylinder 4 to retract, driving the swing push rod 6 to rotate clockwise, and the other side of the cross plate 63 lifts the same side of the swing arm 71, and the cigarette box is lifted by the corresponding box-lifting block. During the process of packing tobacco shreds, the two box-lifting blocks take turns to lift the cardboard box, making the cardboard box swing regularly, so that after the tobacco shreds enter the cardboard box, under the action of gravity and inertia during the bumping and shaking process, they evenly and tightly fill the space inside the cardboard box, filling the internal voids of the cardboard box, thereby increasing the packing weight of the cigarette box. After packing is completed, the solenoid valve controls the piston rod of the lifting cylinder 3 to retract, and the box-lifting block descends below the roller, so that the cigarette box can move from the roller to the next process.

[0047] In summary, the main design concept of the present invention is that at the material receiving station of the manual cardboard box packing line for tobacco shreds, the pneumatic swing mechanism of the present swing loader is used to push the cardboard box above to swing and shake, so that the tobacco shreds falling into the cigarette box evenly and tightly fall inside the cigarette box under the action of gravity and inertia, forming a natural compaction effect. Specifically, the main body of the swing loader is composed of a frame, a roller, a lifting cylinder, a swing cylinder, a lifting link, a swing push rod, a swing link and two box-lifting blocks. The lifting cylinder and the swing cylinder respectively provide driving forces to drive the mechanism assembly composed of the lifting link, the swing push rod and the swing link to achieve lifting and swinging. The box-lifting blocks at both ends of the swing arm with an obtuse bending structure can achieve alternating swinging after rising above the roller, so that the cigarette box at the packing station between the two box-lifting blocks makes corresponding swinging actions. The present invention can increase the packing weight, reduce the transportation cost, reduce the breakage of tobacco shreds, improve the on-site environment and increase the economic benefits.
