On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0026] Please refer to the attached Figure 1-Figure 5 As shown, the utility model provides a technical solution: a fully automatic rice vacuum packaging machine, comprising a base 10, a receiving groove 101 and an elongated cavity 102 are provided on the base 10, a connecting box 16 is fixedly installed on the side of the base 10 close to the receiving groove 101, a sealing mechanism is provided in the connecting box 16, a conveyor belt 18 is provided in the receiving groove 101, and a plurality of isolation rods 181 are fixedly installed on the conveyor belt 18 at equal intervals, a fixed plate 11 is fixedly installed on the side of the base 10 away from the connecting box 16, a limiting mechanism is provided on the side of the fixed plate 11 close to the conveyor belt 18, the limiting mechanism includes a limiting plate 12, the limiting plate 12 is arranged above the isolation rod 181 and is slidably connected to the upper ends of the plurality of isolation rods 181, a first air pump 13 is fixedly installed at both ends of the side of the fixed plate 11 away from the limiting plate 12, and the telescopic ends of the two first air pumps 13 pass through the fixed plate 11 and are fixedly connected to the limiting plate 12.

[0027] Specifically, by placing the rice package to be sealed between adjacent isolation rods 181 on the conveyor belt 18, the position of the rice can be limited by the obstruction of the adjacent isolation rods 181 and the limiting plate 12, so that the rice cannot shift or shake when moving with the conveyor belt 18. At the same time, when sealing smaller rice packages, by simultaneously starting the two first air pumps 13, the telescopic ends of the two first air pumps 13 simultaneously push the limiting plate 12 to slide on the several isolation rods 181 close to the connection box 16, so that the limiting plate 12 fits the bottom end of the smaller rice package, which can effectively limit the smaller rice package, so that the limit can be flexibly adjusted according to the size of the rice package, saving time.

[0028] In one embodiment of the present invention, Figure 1 and Figure 3As shown, a number of rollers 17 are rotatably installed at equal intervals on both sides of the inner wall of the accommodating groove 101, and a conveyor belt 18 is sleeved on the outer surfaces of the rollers 17. A motor 14 is fixedly installed on one side of the base 10. The output end of the motor 14 passes through the base 10 and is fixedly connected to the center end of one of the rollers 17. By starting the motor 14, the output end of the motor 14 drives one of the rollers 17 to rotate, thereby driving the conveyor belt 18 to rotate, and further transporting the rice package to be sealed to the sealing position for vacuum packaging.

[0029] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the sealing mechanism includes two fixed rods 161 fixedly installed between the two ends of the inner wall of the connecting box 16 and the upper end of the base 10, and a movable plate 20 is provided on the two fixed rods 161. The two fixed rods 161 respectively penetrate the movable plate 20 and are slidably connected to the movable plate 20. The upper end of the base 10 and the lower end of the movable plate 20 are respectively fixedly connected with a first heat-sealing pressure plate 103 and a second heat-sealing pressure plate 202 which are symmetrically arranged. The side of the connecting box 16 close to the accommodating groove 101 is open, and grooves 162 are provided on both sides of the open end of the connecting box 16. The two grooves 162 are symmetrically arranged on both sides of the first heat-sealing pressure plate 103. By driving the second heat-sealing pressure plate 202 to slide vertically downward on the two fixed rods 161 to fit the first heat-sealing pressure plate 103, the packaging opening position between the first heat-sealing pressure plate 103 and the second heat-sealing pressure plate 202 can be sealed.

[0030] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, a slide groove 201 is provided in the middle part of the lower end of the movable plate 20, and a movable block 21 is slidably installed in the slide groove 201. The lower side of the movable block 21 away from the open end of the connecting box 16 is set as an inclined surface, which is convenient for the suction pipe 30 to extend into the rice package. The horizontal height of the lower end of the movable block 21 is flush with the lower end of the first heat-sealing pressure plate 103. A spring 22 is fixedly installed between the movable block 21 and the inner wall of the slide groove 201. The lower end of the movable block 21 and the lower end of the second heat-sealing pressure plate 202 have the same hot pressing effect.

[0031] In one embodiment of the present invention, Figure 2 、 Figure 3 and Figure 4As shown, the base 10 is provided with an elongated hole 104 below the connecting box 16, the elongated hole 104 is connected to the elongated cavity 102, a circular gear 24 is rotatably installed in the elongated hole 104, and two symmetrically arranged long toothed rods 23 are slidably installed at both ends of the elongated hole 104, and the two long toothed rods 23 are respectively engaged with the circular gear 24, and the upper ends of the two long toothed rods 23 pass through the connecting box 16 and are slidably connected to the connecting box 16. Both ends of the movable plate 20 are provided with limited Slot 203, the two long tooth rods 23 are fixedly connected to the limiting block 231 on one side close to the movable plate 20, and the two limiting blocks 231 are slidably installed on the lower end of the inner wall of the two limiting slots 203. When the driving circular gear 24 rotates, it can drive the two long tooth rods 23 to slide downward along the inner wall of the elongated hole 104. Under the push of the two limiting blocks 231, the second heat sealing plate 202 on the movable plate 20 can be driven to move vertically downward close to the first heat sealing plate 103.

[0032] In one embodiment of the present invention, Figure 3 and Figure 5 As shown, two symmetrically arranged L-shaped baffles 106 are fixedly connected to the inner wall of the connecting box 16 away from the open end, and a tooth plate 25 is slidably installed between the two L-shaped baffles 106. The lower end of the tooth plate 25 is serrated and meshes with the circular gear 24. An air intake pipe 30 is fixedly installed on the upper end of the tooth plate 25. A positioning sensor is provided on the side of the air intake pipe 30 close to the open end of the connecting box 16. A second air pump 33 is fixedly installed on the outer side of the connecting box 16. The telescopic end of the second air pump 33 passes through the connecting box 16 and is fixedly connected to the tooth plate 25.

[0033] Specifically, when the rice package moves to the connecting box 16 through the conveyor belt 18 and the suction pipe 30 is in the middle position of the rice package after being sensed by the positioning sensor, the positioning sensor sends a signal to turn off the motor 14 and start the second air pump 33 at the same time, so that the telescopic end of the second air pump 33 pushes the tooth plate 25 to move in the two L-shaped baffle bars 106, so that the suction pipe 30 on the tooth plate 25 extends into the rice package. When the tooth plate 25 moves, it can drive the circular gear 24 to rotate in the moving direction of the tooth plate 25, and further drive the two long tooth rods 23 to move vertically downward, and then the two limit blocks 231 respectively push the second heat sealing plate 202 at the lower end of the movable plate 20 in the two limit grooves 203 to fit closely with the first heat sealing plate 103. During the continuous movement of the tooth plate 25, when the second heat sealing plate 202 is close to the first heat sealing plate 103, When sealing the pressure plate 103, the moving block 21 is fitted against the upper end of the suction pipe 30 and the spring 22 is squeezed into a squeezed state. After completing the vacuuming of the rice package, the second air pump 33 is started, and the tooth plate 25 is pulled to separate the suction pipe 30 from the rice package. In the process of the suction pipe 30 separating from the rice package, the limiting blocks 231 on the two long tooth rods 23 move from the lower end of the limiting groove 203 to the upper end, and the second heat-sealing pressure plate 202 is always fitted against the first heat-sealing pressure plate 103. Under the elastic force of the spring 22, the moving block 21 is quickly moved down to fit the first heat-sealing pressure plate 103, and the rice package at the original suction pipe 30 is sealed. During the continuous movement of the tooth plate 25, the limiting blocks 231 on the two long tooth rods 23 push the second heat-sealing pressure plate 202 away from the first heat-sealing pressure plate 103, thereby completing the vacuum packaging of the rice.

[0034] In one embodiment of the present invention, Figure 2 、 Figure 3 and Figure 5 As shown, a vacuum pump 32 is fixedly installed in the elongated cavity 102, and an air suction hole 321 and an air outlet hole 322 are provided on the vacuum pump 32. A connecting hole 105 is provided on the side of the base 10 close to the elongated hole 104. A flexible conduit 31 is fixedly connected to the side of the suction pipe 30 away from the open end of the connecting box 16. The flexible conduit 31 passes through the connecting hole 105 and is fixedly connected to the suction hole 321. Through the vacuum pump 32, the air in the rice package can be sucked out under the transmission of the suction pipe 30 and the flexible conduit 31.

[0035] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, air-permeable plates 15 are fixedly mounted on both sides of the elongated cavity 102 .

[0036] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
