[0026] Example 1

[0027] In a typical implementation of the present invention, Figure 1 and Figure 2 As shown, an end-sealed folding block for a lifting channel of a small box transparent paper cigarette pack of a packaging machine is provided, comprising a folding block 1 and a folding block bracket 2, the folding block bracket 2 is provided with an L-shaped groove, the folding block is installed in the L-shaped groove of the folding block through a bearing and can swing in the L-shaped groove, the folding block 1 is provided with a first permanent magnet piece 3 on the inner side surface of the L-shaped groove, the folding block bracket 2 is provided with a second permanent magnet piece 4 on the inner side surface opposite to the folding block 1, the first permanent magnet piece 3 and the second permanent magnet piece 4 repel each other, and the folding block 1 is made to swing back and forth in the folding block bracket 2 by utilizing the mutually repelling magnetic force generated between the first permanent magnet piece 3 and the second permanent magnet piece 4.

[0028] In this embodiment, through holes are provided at the lower position of both side walls of the L-shaped groove, and bearings 6 are installed in the through holes. A through hole is provided at the top of the folding stopper 1, and the shaft passes through the through hole and is connected to the bearing 6 on the groove wall. The shaft and the folding stopper are fixed by bolts 8, and there is no relative movement between the shaft and the folding stopper, and the swing of the folding stopper is realized by the rotation of the bearing; a limiting column 7 is provided on the upper part of one of the side walls of the L-shaped groove where the folding stopper is installed, and correspondingly, a groove is provided at the position of the folding stopper 1, and the limiting column 7 is located in the groove of the folding stopper, which plays a limiting role in the swing of the folding stopper, and by providing a groove on the folding stopper, the folding stopper protrudes from the surface of the folding stopper bracket in the initial state.

[0029] In this embodiment, the folding stopper 1 is located at the middle position of the inner side of the L-shaped groove to open a groove, the first permanent magnet piece 3 is embedded in the groove and fixed by gluing, the groove area is slightly larger than the first permanent magnet piece 3, which is convenient for the embedding of the first permanent magnet piece 3. No mechanical fixation such as screws is used here, but strong glue is used for bonding. Experimental verification shows that it is firm and has high strength.

[0030] In this embodiment, a groove is provided on the inner side surface of the folding stopper bracket 4 opposite to the folding stopper 2. The second permanent magnet sheet 4 is embedded in the groove and fixed by gluing. The groove area is slightly larger than the first permanent magnet sheet 3, which is convenient for embedding the first permanent magnet sheet 3. Mechanical fixation such as screws is not used here, but strong glue is used for bonding. Experimental verification shows that it is firm and has high strength.

[0031] By providing a groove and embedding the permanent magnet piece in the groove, a better limiting effect can be achieved for the permanent magnet piece.

[0032] Furthermore, the first permanent magnet piece 3 and the second permanent magnet piece 4 are staggered with a distance of 15-20 mm. According to experiments, the first permanent magnet piece 3 and the second permanent magnet piece 4 are slightly staggered, which can achieve a better use state and meet the magnetic field principle.

[0033] In this embodiment, the first permanent magnet piece 3 and the second permanent magnet piece 4 are both made of neodymium iron boron magnets, whose working limit is 80-180° C., and the first permanent magnet piece 3 and the second permanent magnet piece 4 are the same in size.

[0034] In a specific implementation of this embodiment, the first permanent magnet sheet and the second permanent magnet sheet are both made of NdFeB magnets with a specification size of 20×10×2mm, with a maximum operating temperature of 80-180°C, and a temperature at the small box lifting device of 30-60°C. In this environment, the magnetic force of the NdFeB magnets can be ignored, and the service life can reach more than 10 years. At this time, the size of the slots on the folding block and the folding block bracket is 25×15×3mm, wherein the groove on the folding block is located at the center of the inner side of the folding block, and the groove on the folding block bracket is located 20mm to the left of the center of the inner side of the folding block, so as to realize the staggered installation of the first permanent magnet sheet and the second permanent magnet sheet.

[0036] In this embodiment, the folding block bracket 2 is connected to the lifting guide plate 5, and the lifting guide plate 5 is also connected to a plow-type folder (not shown in the figure, which is an existing structure). The plow-type folder serves as the entrance for the transparent paper of the cigarette package to enter the folding block, and is responsible for the first folding of the transparent paper at both ends. The plow-type folder is connected to the folding block bracket 2 by screws.

[0037] The end seal folding block provided in this embodiment is fixed to the original CH lifting channel installation position of the packaging machine, and the elastic force provided by the original torsion spring is changed into magnetic force by using the principle of permanent magnet repulsion. In the initial state, the folding block protrudes from the surface of the folding block bracket under the repulsive force of the two permanent magnetic sheets and the limiting action of the limiting column, and the transparent paper cigarette pack is pushed into the folding channel by the output push plate to complete the folding of the other two folding corners and the lower short side at both ends of the cigarette pack; then the stacking plate lifts the cigarette pack upward, and when it contacts the folding block, the part of the folding block protruding from the surface of the folding block bracket is pressed into the folding block bracket, and the cigarette pack is clamped under the repulsive force of the two permanent magnetic sheets. The cigarette pack is lifted upward by the stacking plate to complete the folding of the upper short sides at both ends, and the cigarette pack stacked into two packs completes heat sealing at both ends in the end sealing channel. After the cigarette pack leaves the folding block, the folding block is reset to the initial state.

[0038] Before use, debug the installed new CH lifting channel, press the folding block manually to check whether the permanent magnet is in place, turn the machine manually to check whether the transparent paper of the cigarette package is folded normally; observe whether there is transparent paper adhesion or double package rejection signal when running at low, medium and high speeds. When the machine is turned to normal speed, the small package of transparent paper is intact, and the folding block of the lifting channel end seal moves smoothly without hysteresis, and the debugging is completed.

[0039] After the GDX2 unit replaced the CH lifting channel end seal folding block, it ran stably, the folding action was flexible and accurate, the downtime rate was reduced, and the effective operation rate of the equipment was effectively improved. The number of maintenance times was reduced, maintenance costs were saved, and maintenance time was saved.

[0040] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
