Description

Technical Field

[0001] The utility model relates to the technical field of tobacco, and particularly relates to a self-suction device for lifting a large pressure plate of a cigarette making machine. Background Technique

[0002] The cigarette gun pressure plate is divided into two parts: a large pressure plate and a small pressure plate. First, the small pressure plate compresses the cut tobacco sent out by the tobacco tongue and wraps it with cigarette paper, compressing the cut tobacco bundle to a diameter slightly smaller than the diameter of a standard cigarette. The other side of the cigarette paper is not restricted by the small pressure plate, but vertically extends out of the forming groove along the fixed side plate for gluing. When it reaches the large pressure plate, the shape at the inlet of the large pressure plate curls the edge of the glued cigarette paper and bonds it with the edge of another curled paper. The large pressure plate is one of the key parts for cigarette rod forming. The shape at the inlet curls the edge of the glued cigarette paper and bonds it with the edge of another curled paper. Its working surface is a semi-circular groove, opposite to the arc of the cigarette gun bottom plate, just forming a cylindrical channel, so that the diameter of the cigarette rod can meet the quality standard requirements.

[0003] The large pressure plate is the working piece that gives the third compression to the cut tobacco bundle in the cigarette gun component. The working surface of the large pressure plate is also a semi-circular groove. It combines with the rear section of the second section of the groove of the cigarette gun bottom plate to form the rear section of the rolling and forming channel - the circular channel. A section at the right end of the large pressure plate overlaps the tail section of the small pressure plate, and a gap is formed without contact at the overlapping section, allowing the cloth tape edge and the cigarette paper edge to be rolled and passed through.

[0004] The large pressure plate wraps the cut tobacco with cigarette paper to form a complete cigarette rod. Therefore, it determines the final diameter of the cigarette rod. The large pressure plate must be installed and adjusted for centering and height according to requirements to ensure that the cigarette paper correctly wraps the cut tobacco. To meet the technical requirements: the arc groove of the large pressure plate should be fully matched with the arc groove of the cigarette gun. It is necessary to frequently lift and lower the four-bar linkage mechanism to drive the large pressure plate to turn up and down for adjustment. Due to the design defect of the ZJ19 cigarette making machine, the large pressure plate four-bar linkage mechanism is extremely prone to free fall when lifted, posing a personal injury to maintenance operators. Therefore, when reversing the four-bar linkage mechanism, manual support or the support of a third party is required, which brings great inconvenience to the maintenance operation.

[0005] According to the space at the large pressure plate part of the equipment and the actual maintenance situation, this application designs a self-suction protection device for lifting the large pressure plate of the ZJ19 cigarette making machine, which can effectively reduce the maintenance time of the large pressure plate and the cigarette gun part, ensure the installation accuracy of the large pressure plate, reduce the safety hazards of maintenance operations, and improve the equipment efficiency.

[0022] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0023] As shown in the figure, a self - suction device for the large pressing plate of a cigarette making machine includes a magnet 1, a positioning plate 2, a hinge mechanism, and a four - link mechanism 4. The following is a detailed description:

[0024] The magnet 1 has a cylindrical structure. A positioning hole is provided at the mid - point of one end of the cylindrical structure, and the positioning hole is used for installing the double - headed screw 11. A threaded hole is provided at the mid - point of the upper end face of the upper hinge 31, and the threaded hole corresponds to the positioning hole in position. The upper end of the double - headed screw 11 is connected to the positioning hole, and the lower end is connected to the threaded hole, thereby realizing the connection between the magnet 1 and the upper hinge 31. Preferably, the diameter of the cylindrical structure is 30 mm and the height is 15 mm; the diameter of the threaded hole is 6 mm and the depth is 4 mm; the diameter of the positioning hole is 6 mm and the depth is 4 mm. Of course, the present application is not limited thereto. The material of the magnet 1 is a magnet.

[0025] The lower end of the positioning plate 2 is fixed to the hinge seat 33 by the positioning plate fixing screw 21. The bottom surface of the hinge seat 33 is connected to the large pressing plate by the large pressing plate fixing screw 34. The number of the above - mentioned screws can be one, two, or more, and the present application is not limited thereto. The positioning plate 2 is a rectangular metal sheet, with a length of 50 mm, a width of 30 mm, and a thickness of 2 mm. The material is metal steel.

[0026] The hinge mechanism includes: an upper hinge 31, a lower hinge 32, and a hinge seat 33 connecting the upper hinge 31 and the lower hinge 32. The upper hinge 31 is connected to the four-bar linkage 4, a magnet 1 is disposed above the upper hinge 31, the rear end of the four-bar linkage 4 is rotatably connected to the hinge seat 33, the lower end of the positioning disk 2 is connected to the hinge seat 33, and the upper end of the positioning disk 2 is located at the rear of the four-bar linkage 4. When the four-bar linkage 4 is lifted upward and rotated, the magnet 1 is magnetically connected to the upper end of the positioning disk 2. A support plate is further disposed between the lower hinge 32 and the upper hinge 31.

[0027] The four-bar linkage 4 is used to fix the upper hinge 31 and can also be used as a handle.

[0028] The principle of the self-suction protection device for the large pressure plate when lifted is based on the action of magnetic force. Magnetic force refers to the force generated by a magnet, and it has the property of attraction. When two magnets approach each other, if their magnetic polarities are opposite, attraction will occur. In a magnetic chuck, the magnet and the chuck have opposite magnetic polarities, so they will attract each other. Specifically, when the magnet approaches the chuck, the magnetic fields between them will interact. Due to the opposite magnetic polarities of the magnet, the magnetic field lines on the chuck will cross the magnetic field lines on the magnet, forming a region with a higher magnetic field intensity. In this region, the magnetic force will attract the magnet and the chuck together, making them fit tightly.

[0029] In actual operation, the large pressure plate is fixed in the four-bar linkage, and the four-bar linkage is connected to the cigarette machine box body. The magnet is installed in the upper hinge at the upper part of the four-bar linkage and can be turned up and down with the four-bar linkage due to operational needs. The positioning disk is connected to the bottom of the four-bar linkage and is a fixed body. When the magnet is turned to the uppermost position with the four-bar linkage, it is attracted to the positioning disk, thus completing the self-suction protection function.

[0030] The self-suction protection device for the large pressure plate when lifted of the ZJ19 cigarette machine not only ensures the part accuracy during the maintenance of the tobacco gun and the large pressure plate, but also can effectively reduce the maintenance time of the tobacco gun assembly, improve the equipment operation efficiency, and effectively eliminate the safety hazards in the maintenance of the large pressure plate at the tobacco gun part.

[0031] Although the present utility model has been disclosed above with embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make various different selections and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model is defined by the claims and their equivalent forms.
