[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1-9 This utility model provides a fully automatic moxa stick packaging machine, including a base 1, and the top of the base 1 is respectively provided with a film covering component 2, a feeding component 4, a cutting component 5 and a heat sealing component 6;

[0029] A short support block 7 and a long support block 8 are fixedly installed on the lower surface of the base 1. A conveying groove 9, a film outlet groove 10, and a square groove 11 are respectively opened on the surface of the base 1. A first conveyor belt is installed on the inner wall of the conveying groove 9. The film outlet groove 10 is fitted onto the outside of the heat shrink film 212. A connecting box 12 is fixedly installed on the inner wall of the square groove 11. A second conveyor belt is installed on the inner wall of the connecting box 12. A baffle 13 is fixedly installed at the top of the base 1. An array plate 14 is fixedly installed on one side of the baffle 13. An electric push rod 15 is fixedly installed on the other side of the baffle 13. The telescopic end of the electric push rod 15 is fixedly connected to the array plate 14. The front side of the array plate 14 slides against the pusher plate 16. The first conveyor belt moves the moxa column array after the heat shrink film 212 is coated and cut to the inside of the heat sealing shell 601 for heating and sealing. The second conveyor belt transports a single moxa column to one side of the array plate 14. The moxa column is held in place by the array plate 14. The next three moxa columns are held in place by the previous moxa column, so the four moxa columns form a row. The electric push rod 15 is activated. The telescopic end of the electric push rod 15 extends and pushes the pusher plate 16. The pusher plate 16 pushes a row of moxa columns to the vicinity of the baffle plate 403. This process is repeated to form the moxa column array.

[0030] The film coating assembly 2 includes a support frame 201 and a limiting assembly 3. The support frame 201 is fixedly installed on one side of the base 1. A vertical plate 202 is fixedly installed at the top of the support frame 201. A sliding groove 203 is opened at the top of the vertical plate 202. A laser rangefinder sensor 204 is fixedly installed on the inner wall of the bottom end of the sliding groove 203. A sliding plate 205 is slidably connected to the inner wall of the sliding groove 203. An L-shaped plate 206 is fixedly installed at the top of the sliding plate 205. A movable frame 207 is fixedly installed at the bottom end of the L-shaped plate 206. Two pressure rollers 208 are rotatably connected to the surface of the movable frame 207 through a rotating shaft. A horn 209 and a film feeding roller 210 are respectively installed at the bottom end of the L-shaped plate 206.

[0031] A current collector box 211 is fixedly installed on the front of the upright plate 202. A microcontroller is fixedly installed inside the current collector box 211. A switch panel 223 is fixedly installed on the front of the current collector box 211. A microcontroller switch is installed on the surface of the switch panel 223. The microcontroller is electrically connected to an external power supply through the microcontroller switch. A horn 209 is fixedly installed on the surface of the current collector box 211. The horn 209 and the laser range sensor 204 are both electrically connected to the microcontroller. A film feeding roller 210 is rotatably installed on one side of the upright plate 202 via a rotating shaft. A heat shrink film 212 is wound around the surface of the film feeding roller 210. The heat shrink film 212 is slidably connected to the contact parts of the two pressure rollers 208. The microcontroller has a preset program inside. The microcontroller receives and processes the distance value transmitted by the laser range sensor 204. The result of the microcontroller's calculation will determine whether to activate the horn 209. A film roll for supplying the heat shrink film 212 is wound around the surface of the film feeding roller 210. The film roll can be replaced on the surface of the film feeding roller 210.

[0032] A dovetail groove 213 is provided on the inner wall of one side of the slide 203. A dovetail block 214 is slidably connected to the inner wall of the dovetail groove 213. One side of the dovetail block 214 is fixedly connected to one side of the slide plate 205. A first retaining ring 215 is fixedly provided on the surface of the film feeding roller 210. A second retaining ring 216 is threadedly connected to the surface of the film feeding roller 210. The dovetail groove 213 restricts the movement range of the dovetail block 214, thereby preventing the slide plate 205 from detaching from the slide 203 or the slide plate 205 from hitting the laser rangefinder 204 downwards. The cooperation of the first retaining ring 215 and the second retaining ring 216 prevents the heat shrink film 212 from shifting excessively when it is wound by the take-up roller 219. Continuously rotating the second retaining ring 216 causes the second retaining ring 216 to separate from the film feeding roller 210, making it easy to replace the film roll.

[0033] A first side plate 217 is fixedly provided at the bottom of the support frame 201. A transmission rod 218 is rotatably connected to one side of the first side plate 217 via a bearing. A take-up roller 219 is fixedly provided at one end of the transmission rod 218. The surface of the take-up roller 219 is bonded to one end of the heat shrink film 212. Two third retaining rings 221 are fixedly provided on the surface of the take-up roller 219. A second side plate 220 is rotatably connected to one end of the take-up roller 219 via a rotating shaft. One side of the second side plate 220 is fixedly connected to the other side of the base 1. A take-up motor 222 is fixedly provided on the other side of the first side plate 217. The take-up motor 222 is a forward and reverse servo motor. The transmission shaft of the take-up motor 222 is fixedly connected to the other end of the transmission rod 218. When the take-up motor 222 is started, the take-up motor 222 drives the transmission rod 218 and the take-up roller 219 to rotate. The take-up roller 219 will take up the heat shrink film 212 whose rectangular portion has been cut off.

[0034] Specifically, after the film roll for supplying heat-shrink film 212 is installed, the L-shaped plate 206 is released. The L-shaped plate 206 moves downward and pushes the slide plate 205, the moving frame 207, and the two pressure rollers 208 to move, causing the two pressure rollers 208 to adhere to the outer surface of the heat-shrink film 212 on the outside of the film roll. When the take-up roller 219 rotates, the heat-shrink film 212 slides relative to the pressure rollers 208, and the thickness of the film roll gradually decreases. The microcontroller is activated by the microcontroller switch, and the laser range sensor 204 measures its own distance from the slide plate 205. The distance between 5 and the preset value is transmitted to the microcontroller. The microcontroller has a preset program that can compare the distance value with the preset value. As the heat shrink film 212 is supplied, the thickness of the film roll becomes thinner. The moving frame 207 is supported by the film roll by two pressure rollers 208. Therefore, the moving frame 207 and the slide plate 205 move downward and reduce the transmission distance value. When the distance value is less than the preset value, the microcontroller activates the speaker 209 to issue an audible warning, reminding the worker to replenish the new film roll in time to ensure the normal operation of the Aizhu packaging machine.

[0035] Example 2:

[0036] The limiting component 3 includes a card holder 301, which is fixedly disposed on the other side of the base 1. The surface of the card holder 301 is respectively provided with a groove 302 and a through hole communicating with the interior of the groove 302. A card block 303 is slidably connected to the inner wall of the groove 302. An anti-detachment groove 304 is provided at the bottom end of the card block 303. A limiting seat 305 and a limiting rod 306 that slides with the through hole are respectively fixedly disposed on one side of the card block 303. A sliding rod 307 is slidably connected to the inner wall of the limiting seat 305. One end of the sliding rod 307 is fixedly connected to one end of the film feeding roller 210. An auxiliary groove 308 communicating with the groove 302 is provided on one side of the card holder 301. An operating plate 309 is slidably connected to the inner wall of the auxiliary groove 308. A reset spring 310 is fixedly disposed between the operating plate 309 and the auxiliary groove 308. An anti-detachment plate 311 that engages with the anti-detachment groove 304 is fixedly disposed at the top of the operating plate 309.

[0037] Specifically, first, push the operating plate 309 downwards to move it downwards. The operating plate 309 will then move the anti-detachment plate 311, causing it to disengage from the anti-detachment groove 304 and releasing the lateral restriction of the anti-detachment plate 311 on the locking block 303. At this time, push the locking block 303 to the right. The locking block 303 will then move the limiting seat 305 away from the slide bar 307. The locking block 303 will then move the limiting rod 306 away from the through hole, releasing the vertical restriction of the locking block 303 by the limiting rod 306. This allows the locking block 303 to be disassembled, facilitating the replacement of the film roll used to supply the heat shrink film 212 from one end of the film feeding roller 210. It should be noted that the slide bar 307 will rotate along the inner wall of the limiting seat 305 when the film feeding roller 210 rotates.

[0038] Example 3:

[0039] The feeding assembly 4 includes a transmission screw 401 and a feeding motor 404. The transmission screw 401 is rotatably mounted on the inner wall of the support frame 201 via a bearing. The surface of the transmission screw 401 is threadedly connected to a pusher plate 402 that slides against the inner wall of the support frame 201 via a screw nut. A baffle plate 403 is fixedly mounted on the back of the pusher plate 402. The feeding motor 404 is fixedly mounted on the front of the support frame 201. The feeding motor 404 is a forward and reverse servo motor. The transmission shaft of the feeding motor 404 is fixedly connected to one end of the transmission screw 401.

[0040] Specifically, the feeding motor 404 drives the pusher plate 402 to move via the transmission screw 401. The pusher plate 402 pushes the moxibustion column array to move, and the moving moxibustion column array squeezes the taut heat shrink film 212, causing the taut heat shrink film 212 to deform into a < shape. Then, the cutting component 5 is started to cut the <-shaped part of the heat shrink film 212, so that the surface of the moxibustion column array is covered with heat shrink film 212. After that, the pusher plate 402 pushes the moxibustion column array and the heat shrink film 212 covering the surface of the moxibustion column array, so that the two move onto the belt of the first conveyor belt. Then, the feeding motor 404 rotates in the opposite direction, causing the pusher plate 402 to return to its original position. At the same time, the winding motor 222 increases its speed until the heat shrink film 212 is taut again and then returns to its original speed.

[0041] Example 4:

[0042] The cutting assembly 5 includes a C-shaped plate 501, which is fixedly mounted on the top of the base 1. Two telescopic cylinders 502 are fixedly mounted on the top of the C-shaped plate 501. A lifting plate 503 that slides against the inner wall of the C-shaped plate 501 is fixedly mounted on the telescopic end of the two telescopic cylinders 502. A slice 504 is fixedly mounted on the bottom end of the lifting plate 503. The slice 504 is configured in the shape of the C-shaped plate.

[0043] Specifically, two telescopic cylinders 502 are activated, and the telescopic ends of the two telescopic cylinders 502 extend and push the lifting plate 503 and the slice 504 downward. After the U-shaped slice 504 cuts the heat shrink film 212 of the <-shaped part, it cuts out a folded rectangular heat shrink film 212 on the surface of the heat shrink film 212, and the rectangular heat shrink film 212 covers the surface of the moxibustion column array.

[0044] Example 5:

[0045] The heat sealing assembly 6 includes a heat sealing shell 601, which is fixedly mounted on the top of the base 1. A first electric heating plate 602 is fixedly mounted on the inner wall of the top and the inner walls on both sides of the heat sealing shell 601. A second electric heating plate 603 is fixedly mounted on the inner wall of the front and the inner wall of the back of the heat sealing shell 601. An inlet 604 and an outlet 605 are respectively opened on the surface of the heat sealing shell 601. A curtain is provided on the inner wall of the inlet 604 and the inner wall of the outlet 605.

[0046] Specifically, the second electric heating plate 603 and the first electric heating plate 602 are activated. The second electric heating plate 603 and the first electric heating plate 602 release heat to raise the temperature inside the heat-sealed shell 601 so that the rectangular heat-shrink film 212 covering the surface of the moxibustion array can adhere and shrink, thus completing the packaging of the moxibustion array.

[0047] In use, after installing the film roll for supplying heat-shrink film 212, the L-shaped plate 206 is released. The L-shaped plate 206 moves downward and pushes the slide plate 205, the moving frame 207, and the two pressure rollers 208 to move, causing the two pressure rollers 208 to adhere to the outer surface of the heat-shrink film 212 on the outside of the film roll. When the take-up roller 219 rotates, the heat-shrink film 212 slides relative to the pressure rollers 208, and the thickness of the film roll gradually decreases. The microcontroller is activated by the microcontroller switch, and the laser range sensor 204 measures its own distance from the slide plate 205. The distance between 5 is measured and transmitted to the microcontroller. The microcontroller has a preset program that can compare the distance value with the preset value. As the heat shrink film 212 is supplied, the thickness of the film roll becomes thinner. The moving frame 207 is supported by the film roll through two pressure rollers 208. Therefore, the moving frame 207 and the slide plate 205 move downward and reduce the transmission distance value. When the distance value is less than the preset value, the microcontroller activates the speaker 209 to issue an audible warning, reminding the worker to replenish the new film roll in time to ensure the normal operation of the Aizhu packaging machine.

[0048] It should be added that the dovetail groove 213 restricts the movement range of the dovetail block 214 to prevent the slide plate 205 from disengaging from the slide groove 203 or from the slide plate 205 from damaging the laser rangefinder 204. The surface of the film feeding roller 210 is threaded with a second retaining ring 216. Continuously rotating the second retaining ring 216 causes the second retaining ring 216 to separate from the film feeding roller 210, pushing the operating plate 309 downward. The operating plate 309 will drive the anti-detachment plate 311 to move, causing the anti-detachment plate 311 to disengage from the anti-detachment groove 304, releasing the lateral limit of the anti-detachment plate 311 on the locking block 303. Then, the locking block 303 is pushed to the right, causing the locking block 303 to drive the limiting seat 305 to disengage from the slide rod 307. The locking block 303 will drive the limiting rod 306 to disengage from the through hole, releasing the vertical limit of the limiting rod 306 on the locking block 303, completing the disassembly of the locking block 303, which is convenient for replacing the film roll used to supply the heat shrink film 212.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
