Description
Technical Field
[0001] The utility model relates to the technical field of cigarette making machines, in particular to a cigarette making machine thread pressing wheel device and a cigarette making machine. Background Art
[0002] A cigarette making machine is a special machine that uses cigarette paper to roll tobacco into cigarettes. The cigarette making machine mainly includes four main functional modules: tobacco supply mechanism, forming mechanism, cutting mechanism and weight control. In addition, some intelligent cigarette making machines also have auxiliary parts such as printing and dust removal.
[0003] After working under high load for a long time, the pressing wheel in the cigarette making machine is prone to wear. If the damaged pressing wheel is not replaced in time, it will further cause the suction belt to wear, and the cigarettes will have quality defects such as high empty rate. The existing pressing wheel is usually installed with smaller bearings at both ends along the axial direction, and the pressing wheel and the bearing are fixed with interference fit, which is very difficult to disassemble and replace, and the operation is time-consuming and labor-intensive, which can easily cause the cigarette making machine to stop for too long, affecting production efficiency and economy.
[0004] In order to solve the above problems, the prior art provides a wire pressing wheel and a cigarette making machine. By directly connecting the bearing to the suction belt, the bearing can play the role of a traditional wire pressing wheel. When the bearing is worn, the bearing is removed from the cigarette making machine and replaced with a new bearing to complete the maintenance. However, there are still some problems with using bearings to replace wire pressing wheels. If ordinary bearings are used, the wear resistance of the outer circumference of the bearing is too low, which leads to the need to frequently replace the bearings, which in turn leads to a long cumulative downtime for maintenance of the equipment, reducing the working efficiency of the cigarette making machine; if customized wear-resistant bearings are used, the cost is high, which increases the burden on the enterprise.

A support shaft 3 is arranged between the first wing plate 1 and the second wing plate 2. A bearing 4 is sleeved on the support shaft 3. An outer ring of the bearing 4 is sleeved with a connecting sleeve 5. A first groove 51 is arranged on an outer peripheral surface of the connecting sleeve 5. A ring-shaped wire pressing wheel 6 is sleeved on the outer periphery of the connecting sleeve 5. The wire pressing wheel 6 is in clearance fit with the connecting sleeve 5. A second groove 61 that is opposite to the position of the first groove 51 is arranged on an inner peripheral surface of the wire pressing wheel 6. The wire pressing wheel device for a cigarette making machine further includes an elastic tightening assembly 7. One end of the elastic tightening assembly 7 is installed in the first groove 51, and the other end is installed in the second groove 61. The elastic tightening assembly 7 is tightly connected between the connecting sleeve 5 and the wire pressing wheel 6. Exemplarily, one end of the elastic tightening assembly 7 can be fixed in the first groove 51. When the wire pressing wheel 6 is installed on the connecting sleeve 5, the elastic tightening assembly 7 retracts under the extrusion of the wire pressing wheel 6, so that the other end of the elastic tightening assembly 7 extends into the second groove 61 and is in tight contact with the wire pressing wheel 6, to ensure a firm connection between the connecting sleeve 5 and the wire pressing wheel 6 without interference fit, reduce the number of collisions between the connecting sleeve 5 and the wire pressing wheel 6, and improve the service life of the connecting sleeve 5 and the wire pressing wheel 6. It should be noted that in this embodiment, the wire pressing wheel 6 is located between the first wing plate 1 and the second wing plate 2 and has a gap with both the first wing plate 1 and the second wing plate 2 to ensure the normal rotation of the wire pressing wheel 6.
[0044] For the wire pressing wheel device of the cigarette making machine in this embodiment, by installing a connecting sleeve 5 on the bearing 4 and installing a wire pressing wheel 6 on the connecting sleeve 5, it ensures that the wire pressing wheel 6 with relatively high wear resistance is used to roll the cut tobacco during the working process, reducing the number of times of replacing the wire pressing parts during the working process, improving the working efficiency of the cigarette making machine, and the annular wire pressing wheel 6 requires less manufacturing material and has a low cost, solving the problem in the prior art that using a bearing to replace the wire pressing wheel results in either frequent replacement of the bearing or too high cost. Moreover, for this wire pressing wheel device of the cigarette making machine, by arranging a first groove 51 on the outer peripheral surface of the connecting sleeve 5 and a second groove 61 on the inner peripheral surface of the wire pressing wheel 6, and both ends of the elastic tightening component 7 are tightly installed in the first groove 51 and the second groove 61 respectively, it can ensure the stable connection between the wire pressing wheel 6 and the connecting sleeve 5, realizing the synchronous rotation of the two, and the wire pressing wheel 6 and the connecting sleeve 5 are in a non-interference fit, which is convenient for disassembly and replacement, and it is easy to remove the wire pressing wheel 6 from the connecting sleeve 5, avoiding the inconvenient situation of taking out during the interference fit, solving the problem in the prior art that the traditional wire pressing wheel is inconvenient to maintain when installed through a small bearing. In addition, in this embodiment, when replacing the wire pressing wheel 6, it is not necessary to replace the bearing 4 together, reducing the cost of single replacement.
[0045] Optionally, a first mounting hole 11 is provided on the first wing plate 1 of this embodiment, a second mounting hole 21 is provided on the second wing plate 2, and both ends of the support shaft 3 are inserted into the first mounting hole 11 and the second mounting hole 21 respectively.

Of course, in other embodiments, other methods can also be used to fix the support shaft 3 between the first wing plate 1 and the second wing plate 2, and the first wing plate 1 and the second wing plate 2 can be connected by fasteners. Further, the inner ring of the bearing 4 and the support shaft 3 are in an interference fit, and the outer ring of the bearing 4 and the connecting sleeve 5 are in an interference fit. In this way, while ensuring the stable rotation of the connecting sleeve 5 relative to the support shaft 3, the installation reliability and use safety of the device are improved.
[0046] In this embodiment, the wire pressing wheel 6 is made of cemented carbide material to improve the wear resistance of the wire pressing wheel 6, extend its service life, reduce the number of replacements of the wire pressing wheel 6, and thus reduce the cost. In other embodiments, the wire pressing wheel 6 can also be made of stainless steel and a wear-resistant coating is provided on its surface, which can also increase the wear resistance of the wire pressing wheel 6.
[0047] Optionally, the elastic pressing component 7 of this embodiment includes a first connection key 71, a second connection key 72, and an elastic member 73. The first connection key 71 is disposed in the first groove 51, the second connection key 72 is disposed in the second groove 61, and there is a gap between the first connection key 71 and the second connection key 72; the elastic member 73 is tightly pressed between the first connection key 71 and the second connection key 72, and can make the first connection key 71 tightly press against the first groove 51, and the second connection key 72 tightly press against the second groove 61. In this embodiment, the elastic pressing component 7 is set as a split first connection key 71 and second connection key 72, which is convenient for installation and disassembly, and enables the first connection key 71 and the second connection key 72 to be made of metal materials, greatly improving its structural strength; and the elastic member 73 provided between the first connection key 71 and the second connection key 72 ensures that the elastic pressing component 7 can be elastically pressed between the connecting sleeve 5 and the wire pressing wheel 6. Further, a first clamping groove 711 is provided on the side of the first connection key 71 opposite to the second connection key 72, and a second clamping groove is provided on the side of the second connection key 72 opposite to the first connection key 71, and the elastic member 73 is clamped between the first clamping groove 711 and the second clamping groove. In this embodiment, the first connection key 71 can be fixed in the first groove 51, the second connection key 72 can be fixed in the second groove 61, and the elastic member 73 can be fixed in the first clamping groove 711. In this way, when the wire pressing wheel 6 is installed on the connecting sleeve 5, the elastic member 73 is squeezed and retracted. When the elastic member 73 enters the second clamping groove, the assembly of the wire pressing wheel 6 and the connecting sleeve 5 is completed, and the operation is simple and easy. In the present utility model, the elastic member 73 can be selected from a spring, a rubber ball, etc. Preferably, the elastic member 73 of this embodiment adopts a rubber ball, which has a simple structure, is convenient for installation, and has a low cost.
[0048] Of course, in other embodiments, the elastic pressing component 7 can also be an integral elastic structure, for example, an integral rubber block is adopted. One end of the rubber block is fixed in the first groove 51, and the other end can abut against the second groove 61, so as to realize the tight connection between the wire pressing wheel 6 and the connecting sleeve 5.
[0049] Optionally, the number of the first grooves 51 is at least two, and at least two first grooves 51 are arranged at equal intervals along the circumferential direction of the connecting sleeve 5; and the number of the second grooves 61 is equal to that of the first grooves 51 and is arranged in one-to-one correspondence; the number of the elastic pressing components 7 is equal to that of the first grooves 51 and is arranged in one-to-one correspondence. The tight connection between the connecting sleeve 5 and the wire pressing wheel 6 is realized through at least two groups of elastic pressing components 7, which increases the connection reliability and improves the force balance of the wire pressing wheel 6. Exemplarily, four first grooves 51 are evenly arranged on the outer peripheral surface of the connecting sleeve 5 in this embodiment, four second grooves 61 are evenly arranged on the inner peripheral surface of the wire pressing wheel 6, and four groups of elastic pressing components 7 are respectively tightly installed in the corresponding first grooves 51 and second grooves 61.

The first retaining ring 8 is sleeved on the support shaft 3, and both ends of the first retaining ring 8 are respectively abutted against the first wing plate 1 and the inner ring of the bearing 4. At the same time, a second retaining ring 9 is provided between the second wing plate 2 and the bearing 4. The second retaining ring 9 is sleeved on the support shaft 3, and both ends of the second retaining ring 9 are respectively abutted against the second wing plate 2 and the inner ring of the bearing 4. By providing the first retaining ring 8 and the second retaining ring 9, it is possible to prevent the bearing 4 from moving left and right on the support shaft 3 during the working process, ensuring the stability of the device operation. Further, there is a clearance fit between the first retaining ring 8 and the support shaft 3, and there is a clearance fit between the second retaining ring 9 and the support shaft 3. In this way, the connections between the first retaining ring 8, the second retaining ring 9 and the support shaft 3 are all non-interference fits, facilitating the removal of the first retaining ring 8 and the second retaining ring 9 from the support shaft 3 during subsequent maintenance.
[0051] When assembling the wire pressing wheel device of the cigarette making machine in this embodiment, first install the bearing 4 on the support shaft 3, then install the connecting sleeve 5 on the bearing 4, and then detachably install the wire pressing wheel 6 on the connecting sleeve 5 through the elastic pressing component 7. After that, install the first retaining ring 8 and the second retaining ring 9 on the support shaft 3, and finally install the above assembled body together between the first wing plate 1 and the second wing plate 2 to complete the assembly. When the wire pressing wheel 6 is worn and needs to be replaced after working for a period of time, at least one of the first wing plate 1 and the second wing plate 2 can be removed axially, and at least one of the first retaining ring 8 and the second retaining ring 9 can be removed, and then the wire pressing wheel 6 can be removed from the connecting sleeve 5. At this time, a new wire pressing wheel 6 can be replaced. The disassembly and replacement operation of the wire pressing wheel 6 in this embodiment is simple, time-saving and labor-saving, which is beneficial to reducing the downtime of the cigarette making machine, improving production efficiency and reducing production costs.
[0052] This embodiment also provides a cigarette making machine, including the above-mentioned wire pressing wheel device of the cigarette making machine, which can realize the rolling operation of the cut tobacco through the wire pressing wheel 6. This cigarette making machine solves the problems in the prior art that the wire pressing wheel is installed with a small bearing and the maintenance is inconvenient, and the problems that either the bearing needs to be frequently replaced or the cost is too high when using a bearing to replace the wire pressing wheel.
