Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, in particular to an improved device for overlapping packages of a tobacco packaging machine. Background Art

[0002] The ZB45 hard box and hard strip packaging machine is a unit transformed by introducing foreign models and combining domestic technologies, and is a relatively popular hard strip packaging unit at the present stage. Among them, the YB55 outer box transparent paper packaging machine, as an important part, has the functions of wrapping transparent paper outside the small box of cigarettes, improving the aesthetic degree of cigarette packaging and providing high-quality sealing to achieve moisture-proof, etc. Reasonable use of this unit can effectively improve product characteristics and ensure product quality. However, it is found after actual use that the original lifting and overlapping package design method of the YB55 packaging machine has defects, and equipment failures such as transparent paper corner folding and cigarette package adhesion, sliding baffle wear and torsion spring fracture frequently occur, which are likely to cause product quality problems. The movable block of this device relies on the pressure of the torsion spring to realize the reset function and complete the reciprocating swing. Limited by the structure, friction is inevitably generated between the torsion spring pressing arm and the surface of the movable block during the movement process. The high-frequency movement of the torsion spring is extremely likely to cause wear of the horizontal pressing arm of the torsion spring under long-term action, resulting in fatigue and breakage; wear occurs on the surface of the movable block, causing the movable block to not return to its normal position; in addition, with the high-frequency reciprocating movement of the movable block, the extrusion impact force of the cigarette package will also exceed the fatigue limit of the torsion spring, causing wear and even fatigue breakage of the two stress arms of the torsion spring, reducing the service life of the torsion spring and resulting in the phenomenon of frequent replacement of the torsion spring. The mechanical wear of the torsion spring causes parts replacement and wastes a lot of maintenance time, increases the equipment maintenance workload, and causes unnecessary losses; the wear of the cigarette package movable block will seriously affect the fixed position of the torsion spring, making the cigarette package movable block unable to return to its correct position, resulting in misalignment of the folded transparent paper due to mutual friction, and the transparent paper of the subsequent cigarette package will overlap with it, and after heat sealing with the soldering iron, the transparent papers of the two cigarette packages will adhere to each other, resulting in the situation of connected packages. If the cigarette packages are adhered together and the two cigarette packages cannot be successfully separated, it will cause cigarette package blockage, frequently cause malfunction shutdown, and reduce the production efficiency of the equipment. Slight adhesion of cigarette packages and poor folding of cigarette packages will rotate and convey along with the turning wheel, and cannot be correctly identified and removed when passing through the rejection position. They are pushed out of the wheel by the output push rod, and then enter the next packaging process through the cigarette package beautifier and into the strip box, ultimately causing serious quality problems of the product.

The sliding block 1 is the main part of the improved device for overlapping packaging, having a cuboid structure and being centrally installed in the groove of the folding frame 4. The rolling bearing 2 is used to install the small shaft 3, and the bearing model with an inner diameter equal to the diameter of the small shaft 3 is selected. The small shaft 3 is cylindrical and is inserted into the sliding block 1 with an interference fit therebetween. The folding frame 4 is the main body of the entire overlapping packaging device, and circular holes are provided on both sides of the groove for installing the rolling bearings 2, with the diameter of the circular holes being equal to the outer diameter of the rolling bearings 2. Three spring positioning holes are evenly designed and processed around the center on the inner side above the folding frame 4, and the positioning holes are slightly larger than the circumference of the spring 5. The spring 5 is cylindrical and rebounds and resets the sliding block 1. The screw 6 is an ordinary countersunk hexagon socket head bolt for fixing the sliding block 1 and the small shaft 3. The pin 7 is cylindrical and slightly shorter in length, and is installed on one side in the groove of the folding frame 4 to limit the elastic return position of the sliding block 1;

[0022] The sliding block 1 is the main part of the improved device for overlapping packaging, having a cuboid structure. A long pin hole is provided at the bottom to centrally install the sliding block 1 in the groove of the folding frame 4. The front face of the sliding block 1 folds down the upper wing transparent paper at both ends of the lifted cigarette packet and clamps and holds the lifted cigarette packet in place. Three spring positioning holes are evenly designed and processed around the center on the inner side above the folding frame 4, and the positioning holes are slightly larger than the circumference of the spring 5;

[0023] The rolling bearings 2 are installed in the fixed holes on both sides of the groove of the folding frame 4 for installing the small shaft 3 to enable the sliding block 1 to be flexibly reset, and the bearing model with the same diameter as the small shaft 3 is selected;

[0024] The small shaft 3 is cylindrical and is inserted into the sliding block 1 with an interference fit therebetween, and both ends of the small shaft 3 are installed in the rolling bearings 2;

[0025] The folding frame 4 is the main body of the entire overlapping packaging device. Circular holes are provided on both sides of the groove for installing the rolling bearings 2, with the diameter of the circular holes being equal to the outer diameter of the rolling bearings 2. Three circular positioning holes with a depth of 3 mm and a diameter of 6 mm are evenly designed and processed around the center on the inner side above the folding frame 4, corresponding to the positioning holes on the sliding block 1 and cooperating to install the spring 5;

[0026] The spring 5 is cylindrical. When the cigarette packet is lifted in place, it resets the sliding block 1 and clamps and holds the cigarette packet.

[0029] Working principle: Re-select the cylindrical compression spring piece to replace the original torsion spring piece, so that each swing of the movable block only changes the compression amount of the compression spring. On the premise that the structure of the cigarette packet movable block of the packet folding device remains unchanged and the effect is the same, the sliding friction between the spring 5 and the sliding block 1 is reduced, the force on the cigarette packet movable block becomes uniform, the impact force of the spring 5 is reduced, it is easy to receive the impact from the top and bottom of the cigarette packet, the spring 5 is less worn and not easily broken, and the service life of the equipment is extended. In addition, the reaction force of the spring 5 will not cause wear to the cigarette packet movable block, and the structural defect in the original design can be effectively solved without changing the structure, avoiding quality accidents and improving production efficiency.
