[0048] The rack 10 and the loading table 3 installed on the rack 10, the loading table 3 is provided with a blanking hole; the wall plate is provided with two plates, which are fixedly installed at two ends of the bottom surface of the loading table 3 along the horizontal direction (indicated by the Y direction in the middle);The cigarette receiving device 7 is arranged below the blanking hole, and the two ends of the cigarette receiving device 7 are connected with the two wall plates respectively, and the cigarette receiving device 7 can move along the vertical direction (indicated by the X direction in the middle). Figure 1 Figure 1

[0049] In the embodiment, the top of the loading table 3 is further provided with a limiting table 11, the limiting table 11 is installed on the rack 10, the limiting table 11 is provided with a stacking hole, the cigarette is moved to the loading table 3 through the previous process, the limiting table 11 limits the height of the cigarette flow, prevents the cigarette from being damaged due to the high height of the cigarette accumulation, and the cigarette flow is stacked on the loading table 3, falls into the cigarette receiving device 7 below through the blanking hole, and moves along the vertical direction after receiving the cigarette, so that the effect of automatically receiving the cigarette is realized.

[0050] Optionally, the two ends of the cigarette receiving device 7 are slidably installed on the wall plates through the driving parts respectively.

[0051] Referring to Figure 2 Optionally, the driving part comprises: a rack 4 fixedly installed on the wall plate and laid to the bottom of the wall plate along the vertical direction; a servo motor 6 arranged on one side of the rack 4, a driving gear 5 is arranged on the driving shaft of the servo motor 6, and the driving gear 5 is in meshing connection with the rack 4.

[0052] In one of the embodiments of the application, the rack 4 can be fixed on the wall plates on both sides of the rack 10, the length of the rack 4 can be 40 cm, the width is 2 cm, and the tooth height is 2 cm. The rack 4 is in meshing connection with the driving gear 5, the driving gear 5 is installed on the output shaft of the servo motor 6, and the servo motor 6 is fixedly installed with one end of the cigarette receiving device 7. The servo motor 6, the driving gear 5, the rack 4 and the two washers 9 are respectively installed on the wall plates on both sides of the rack 10, and the two servo motors 6 are synchronous servo motors, so as to synchronously drive the cigarette receiving device 7 to work.

[0053] And through the test, when the driving gear 5 of the servo motor 6 is in meshing connection with the rack 4, the servo motor 6 can stably drive the cigarette receiving device 7 to move back and forth along the vertical direction, without other supporting conditions.

[0054] Optionally, the cigarette tray loading machine can further comprise: a control device arranged on the rack 10 and connected with the servo motor 6; a high-position proximity switch 1 arranged above the loading table 3 and connected with the control device; and a low-position proximity switch 8 arranged at the bottom of the wall plate and connected with the control device. Specifically, the connection mode of the control device with the servo motor 6 and / or the high-position proximity switch 1 and / or the low-position proximity switch 8 can be signal connection.

[0055] ​In this embodiment, the high proximity switch 1 is arranged at the preset height of the feeding table 3, which is used to pre-store some cigarettes on the feeding table 3 when feeding in the previous process, so as to prevent the gap between the cigarette receiving device 7 and the feeding table 3 caused by the feeding speed being less than the descending speed of the cigarette receiving device 7 when the cigarette receiving device 7 descends, and thus prevent the cigarette from being damaged when feeding in the subsequent process. The low proximity switch 8 prevents the servo motor 6 from being separated from the rack 4 when the servo motor 6 descends, so as to prevent the cigarette receiving device 7 from falling.

[0056] When the feeding table 3 starts to fill the cigarettes, the cigarette receiving device 7 is located at the discharging port of the feeding table 3. When the cigarette passes through the discharging port of the feeding table 3, the cigarette receiving device 7 accumulates the cigarettes at the discharging port. When the cigarettes are accumulated to a certain height, the high proximity switch 1 is blocked by the cigarettes. The high proximity switch 1 transmits a high starting signal to the control device. The control device controls the two servo motors 6 on the wall plate to be connected in circuit, and the two servo motors 6 drive the driving gear 5 to rotate and move vertically along the rack 4 synchronously. The cigarette receiving device 7 moves vertically along the wall plate synchronously under the driving of the two servo motors 6. When the servo motor 6 moves to the bottom of the wall plate, the low proximity switch 8 arranged on the wall plate is triggered, and the control device controls the servo motor 6 to stop running. During the whole feeding process, the cigarettes on the feeding table 3 are continuously filled and fall into the cigarette receiving device 7 through the discharging port. When the filling speed of the cigarettes on the feeding table 3 is greater than the automatic filling speed of the cigarettes after the servo motor 6 stops running, the high proximity switch 1 is blocked by the cigarettes again. At this time, the control device controls the filling of the cigarettes on the feeding table 3 to be temporarily suspended until the high proximity switch 1 is no longer blocked by the cigarettes.

The volute spring 24 is arranged in the frame wheel 22, and the two ends of the volute spring 24 are fixedly connected with the wheel shaft 23 and the frame wheel 22 respectively. The baffle 25 is arranged at the bottom of the outer shell 21, and one end of the baffle 25 is fixedly connected with the frame wheel, and the other end of the baffle 25 extends out of the opening and is fixedly connected with the cigarette receiving device 7.

[0059] In this embodiment, the roll type telescopic guard plate 2 is arranged on both sides of the blanking opening, two are arranged, the wheel shaft 23 is installed at the center of the inside of the shell 21, the volute spring 24 is made of carbon steel material with certain toughness, one end is fixedly connected with the wheel shaft 23, the other end is fixedly connected with the frame wheel 22, the guard plate 25 is arranged in the shell 21, and the strip steel wrapping the frame wheel 22 is fixedly connected with the frame wheel 22, and the other end extends out of the opening and is fixedly connected with the cigarette receiving tool 7. When the driving part drives the cigarette receiving tool 7 to move in the vertical direction, the guard plate 25 is driven to extend in the vertical direction, the guard plate 25 drives the frame wheel 22 to rotate, the frame wheel 22 drives the volute spring 24 to shrink under stress and deform, when the cigarette receiving tool 7 needs to return, the external force applied by the driving part disappears, the volute spring 24 needs to restore to the original state, drives the frame wheel 22 to rotate in the opposite direction, the frame wheel 22 drives the guard plate 25 to recover, and the guard plate 25 drives the cigarette receiving tool 7 to move in the opposite direction in the vertical direction, thereby realizing the automatic recovery function of the cigarette receiving tool 7.

[0060] As shown in Figure 4 Optionally, the cigarette receiving tool 7 can include: a first cigarette receiving disc 71 connected with one of the servo motors 6, the first cigarette receiving disc 71 being provided with first mounting holes distributed at equal intervals in the horizontal direction; a second cigarette receiving disc 72 connected with the first cigarette receiving disc 71 and the other servo motor 6 respectively, the second cigarette receiving disc 72 being provided with second mounting holes distributed at equal intervals in the horizontal direction, the second mounting holes having the same size as the first mounting holes; and a plurality of tooth nails 73 respectively installed in the first mounting holes and the second mounting holes. The first cigarette receiving disc 71 and the second cigarette receiving disc 72 can slide relative to each other in the horizontal direction, and the tooth nails 73 installed in the first mounting holes and the tooth nails 73 installed in the second mounting holes are arranged alternately.

[0061] Optionally, the first cigarette receiving disc 71 is fixedly connected with one of the servo motors 6, and the second cigarette receiving disc 72 is fixedly connected with the other servo motor 6.

[0062] In this embodiment, the conventional cigarette has a diameter of 0.77 cm and a length of 8.4 cm. The tooth nail has a diameter of 0.5 cm, a length of 10 cm, and a spacing of 1 cm. The first cigarette receiving disc 71 has a L-shaped structure, and the second cigarette receiving disc 72 is arranged in mirror image symmetry with the first cigarette receiving disc 71. One end of each of the first cigarette receiving disc 71 and the second cigarette receiving disc 72 is fixedly connected with the driving part and arranged on two wallboards. The length of each of the first cigarette receiving disc 71 and the second cigarette receiving disc 72 is 52 cm. The number of tooth nails on each of the first cigarette receiving disc 71 and the second cigarette receiving disc 72 is 34. The first cigarette receiving disc 71 is provided with a “T”-shaped sliding groove 711 at the bottom, and the second cigarette receiving disc 72 is provided with a “T”-shaped protrusion corresponding to the sliding groove 711. The protrusion is installed along the sliding groove 711 and can slide along the sliding groove 711 in the horizontal direction (indicated by the Y direction in the figure) back and forth. Figure 1

[0063] ​The positions of the tooth pegs on the first and second cigarette receiving trays 71 and 72 are staggered up and down, and the vertical projection planes of the tooth pegs on the first and second cigarette receiving trays 71 and 72 are horizontally adjacent to each other, so that the distance between the tooth pegs on the vertical projection planes of the first and second cigarette receiving trays 71 and 72 is 0.5 cm, which is smaller than the diameter of a cigarette, and the cigarettes can be received and will not fall off.

[0064] Optionally, the cigarette receiving device further comprises two gaskets 9 arranged in the tooth gaps at the bottom of the rack 4, and the servo motor 6 can be moved onto the gaskets 9, so that the servo motor 6 is moved in the horizontal direction, and the tooth pegs 73 on the first and second cigarette receiving trays 71 and 72 fixedly connected with the servo motor 6 are moved from the adjacent vertical projection planes to the vertical projection planes of the tooth pegs 73.

[0065] In this embodiment, the length of the rack 4 is 40 cm, the width is 2 cm, and the tooth height is 2 cm. The gaskets 9 at the bottom of the rack 4 have a height of 0.5 cm. The servo motor 6 drives the cigarette receiving tool 7 to move to the bottom of the rack 4, and the two drive gears 5 are synchronously moved to the gaskets 9. The two gaskets 9 move the drive gears 5 in the current horizontal direction by 0.5 cm respectively, the two servo motors 6 are synchronously moved by 0.5 cm, and the first and second cigarette receiving trays 71 and 72 installed on the servo motors 6 are synchronously moved by 0.5 cm. The tooth pegs 73 on the first and second cigarette receiving trays 71 and 72 are changed from the staggered arrangement on the vertical projection planes to the overlapped arrangement. At this time, the distance between the tooth pegs 73 on the vertical projection planes of the first and second cigarette receiving trays 71 and 72 is 1 cm, which is greater than the diameter of a conventional cigarette, i.e. 0.77 cm. The cigarettes fall from the gap between the tooth pegs 73 on the first and second cigarette receiving trays 71 and 72 to the drop roller on the next process, and the automatic filling of the cigarettes is completed.

[0066] In summary, when the cigarette loading table 3 starts to fill the cigarettes, the cigarette receiving device 7 is located at the discharge port of the cigarette loading table 3, and the vertical projection planes of the first cigarette receiving disc 71 and the second cigarette receiving disc 72 are horizontally adjacent to each other. When the cigarettes fall through the discharge port of the cigarette loading table 3, the cigarettes are accumulated at the discharge port. When the cigarettes are accumulated to a certain height, the cigarettes block the high-level proximity switch 1, and the high-level proximity switch 1 transmits a blocking signal to the control device. The control device controls the two servo motors 6 on the wall plate to be connected in circuit, and the two servo motors 6 synchronously drive the driving gear 5 to rotate and move vertically along the rack 4. The first cigarette receiving disc 71 and the second cigarette receiving disc 72 are synchronously moved vertically along the two servo motors 6. The two roll-type retractable guards 2 are respectively fixedly connected to the adjacent first cigarette receiving disc 71 or the second cigarette receiving disc 72. The connection points of the guard plates 25 of the two roll-type retractable guards 2 are respectively arranged close to the connection points of the first cigarette receiving disc 71 or the second cigarette receiving disc 72 and the servo motor 6. The driving gear 5 drives the first cigarette receiving disc 71 and the second cigarette receiving disc 72 to move vertically, and further drives the roll-type retractable guards 2 to work, so as to pull out the guard plates 25 arranged on the first cigarette receiving disc 71 and the second cigarette receiving disc 72. The cigarettes falling through the discharge port are continuously dropped onto the first cigarette receiving disc 71 and the second cigarette receiving disc 72. The guard plates 25 and the first cigarette receiving disc 71 and the second cigarette receiving disc 72 moving vertically form a trapezoidal area for bearing the cigarettes, and the guard plates 25 protect the cigarettes dropped onto the first cigarette receiving disc 71 and the second cigarette receiving disc 72 from falling or scattering.

[0067] When the filling of the cigarettes is completed, the control device controls the servo motor 6 to return vertically. At this time, the volute spring 24 of the roll-type retractable guard 2 needs to be restored to the original state, and drives the frame wheel 22 to rotate in the opposite direction. The frame wheel 22 drives the guard plate 25 to be recovered, and the guard plate 25 drives the first cigarette receiving disc 71 and the second cigarette receiving disc 72 to move in the opposite direction vertically. The servo motor 6 and the roll-type retractable guard 2 jointly realize the function of automatically recovering the first cigarette receiving disc 71 and the second cigarette receiving disc 72.

[0068] Although the application has been illustrated and described with reference to certain preferred embodiments thereof, it should be understood by the skilled in the art that the foregoing is a further detailed description of the application in connection with specific embodiments, and is not intended to limit the application to the specific embodiments. The skilled in the art can make various changes in form and details without departing from the spirit and scope of the application, including making a number of simple deductions or substitutions.
