It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0032] Reference Figure 1-Figure 9A fruit automatic packaging equipment includes a packaging machine 1, a stepper motor 2, a turntable 3, a loading rod 4, a guide roller 5, a first distance sensor 6, a first electric push rod 7, a first clamping plate 8, an air pump 9, a second electric push rod 11, a second clamping plate 12, a hot melter 13, a controller 14, a feeding mechanism and a tensioning mechanism. The stepper motor 2 is installed at the lower rear part of the packaging machine 1 by bolts, and the turntable 3 is connected to the output shaft of the stepper motor 2. The left and right sides of the front side of the turntable 3 are rotatably connected to the loading rod 4. The left side of the packaging machine 1 is rotatably connected to the guide roller 5, and the guide roller 5 can guide the packaging film to make the packaging film more neat. The first distance sensor 6 is installed at the lower left part of the packaging machine 1 by bolts. The first distance sensor 6 is flush with the loading rod 4 on the left side. The first electric push rod 7 is installed at the front and rear sides of the right part of the packaging machine 1 by bolts. The left ends of the telescopic rods of the two first electric push rods 7 are connected together. A first clamping plate 8 is connected, and the first clamping plate 8 is a hollow structure. An air pump 9 is installed on the front side of the top of the first clamping plate 8 by bolts. The air inlet end of the air pump 9 is connected to the front side of the first clamping plate 8, and the air inlet end of the air pump 9 is communicated with the first clamping plate 8. Suction holes 10 are evenly spaced at the bottom of the first clamping plate 8. Second electric push rods 11 are installed on both sides of the front and rear of the lower left part of the packaging machine 1 by bolts. The upper ends of the telescopic rods of the two second electric push rods 11 are commonly connected to the second clamping plate 12. Heat fusers 13 are installed on the left and right sides of the first clamping plate 8 and the left and right sides of the second clamping plate 12 by bolts. A controller 14 is installed on the upper front side of the packaging machine 1 by bolts. The stepper motor 2, the first distance sensor 6, the first electric push rod 7, the air pump 9 and the second electric push rod 11 are all electrically connected to the controller 14. The feeding mechanism is used to transport the fruit into the packaging machine 1, and the packaging machine 1 is provided with a tensioning mechanism for tightening the packaging film.

[0033] Reference Figure 7 and Figure 8 The feeding mechanism includes a frame 151, a conveyor belt 153, a conveyor rod 154, a conveyor 155 and a material collection box 156. A V-shaped groove 152 is opened in the middle of the top of the frame 151, and the V-shaped groove 152 corresponds to the feeding end of the packaging machine 1. A conveyor belt 153 is installed in the frame 151, and conveyor rods 154 are evenly spaced and connected to the conveyor belt 153. The conveyor rods 154 are located in the V-shaped groove 152. The distance between two adjacent conveyor rods 154 is just enough to accommodate one fruit, ensuring that only a single fruit is packaged each time. A material collection box 156 is connected to the left side of the top of the conveyor 155.

[0034] Reference Fig. 9 The tensioning mechanism includes a mounting plate 161, a slide rail 162, a slider 163 and a tensioning roller 164. The mounting plate 161 is connected to the lower left part of the packaging machine 1 by bolts, and the front and rear sides of the top of the mounting plate 161 are connected to the slide rails 162 by bolts. The sliders 163 are slidably connected to the slide rails 162, and the tensioning roller 164 is rotatably connected between the two sliders 163.

[0035] The staff puts two rolls of packaging film on the two loading rods 4 respectively, then passes the packaging film on the left loading rod 4 around the guide roller 5 and the tensioning roller 164 and puts it into the packaging machine 1. The packaging film can be tightened by the gravity of the tensioning roller 164 to prevent the packaging film from being loose, and then the fruit is put into the gathering box 156. The gathering box 156 gathers the fruit into the conveyor 155. The conveyor 155 conveys the fruit to the right and conveys the fruit to the V-shaped groove 152. The fruit will fall between the two adjacent conveying rods 154. The conveyor belt 153 drives the conveying rod 154 to rotate. The conveying rod 154 conveys the fruit to the right and conveys the fruit to the packaging machine 1. The packaging machine 1 automatically packs the fruit. The packaged fruit is sent out from the discharge end of the packaging machine 1. The first distance transmission The sensor 6 can detect the distance between the first distance sensor 6 and the packaging film on the left loading rod 4. The conveying rod 154 continuously conveys the fruit to the packaging machine 1, and the packaging machine 1 continuously packages the fruit. As time goes by, the packaging film on the left loading rod 4 gradually decreases, and the distance between the first distance sensor 6 and the packaging film on the left loading rod 4 becomes farther and farther. When the packaging film on the left loading rod 4 is consumed, the tail end of the packaging film on the left loading rod 4 will fall onto the second clamping plate 12, and the first distance sensor 6 will send a signal to the controller 14, and the controller 14 will control the telescopic rod of the first electric push rod 7 to extend, driving the first clamping plate 8 to move to the left, and at the same time the controller 14 will control the air pump 9 to work, and the air pump 9 will pump air, and the outside The air suction hole 10 is sucked into the first clamping plate 8. When the first clamping plate 8 moves to the left, it will pass above the right loading rod 4. The air pump 9 can suck the head end of the packaging film on the right loading rod 4 onto the first clamping plate 8. At this time, the first clamping plate 8 continues to move to the left, and the first clamping plate 8 can pull out the packaging film on the right loading rod 4. When the first clamping plate 8 moves to the left to just above the second clamping plate 12, the controller 14 will control the first electric push rod 7 to close. At the same time, the controller 14 will control the telescopic rod of the second electric push rod 11 to extend, driving the second clamping plate 12 to move upward, the second clamping plate 12 and the first clamping plate 8 clamp the packaging film, and the hot melter 13 can hot-melt the packaging film to weld the two packaging films together. At this time, the packaging machine 1 is still packaging the fruit. The packaging film is continuously consumed, and the second clamping plate 12 and the first clamping plate 8 have clamped the packaging film, so the packaging film will pull the tensioning roller 164 to move upward. Under the gravity of the tensioning roller 164, the packaging film can be continuously tightened. After the packaging film is welded, the controller 14 will control the telescopic rod of the second electric push rod 11 to shorten, drive the second clamping plate 12 to move downward and reset, and loosen the packaging film. The tensioning roller 164 moves downward under the action of its own gravity. At the same time, the controller 14 will control the telescopic rod of the first electric push rod 7 to shorten, drive the first clamping plate 8 to move rightward and reset, and at the same time, the controller 14 will control the air pump 9 to turn off. After the telescopic rod of the first electric push rod 7 is shortened and reset, the controller 14 will control the output shaft of the stepping motor 2 to rotate 180 degrees.The turntable 3 is driven to rotate 180 degrees, and the turntable 3 drives the loading rod 4 to rotate 180 degrees, and the two loading rods 4 are swapped, and the packaging film is automatically replaced, which has higher continuity and can continuously package the fruits, thereby improving the overall work efficiency.

[0036] Reference Fig.10 and Fig.11 , also includes a storage box 17, a first double-axis cylinder 18, a first stopper 19, a second double-axis cylinder 20, a second stopper 21 and a second distance sensor 22. The storage box 17 is connected to the right rear side of the top of the frame 151 by bolts. Two first double-axis cylinders 18 are installed on the right rear side of the top of the frame 151 by bolts. The two first double-axis cylinders 18 are arranged opposite to each other on the left and right. The storage box 17 is located between the two first double-axis cylinders 18. The telescopic rods of the first double-axis cylinders 18 are connected to the first stopper 19. The two first stoppers 19 slide through the storage box 17 respectively. On the left and right sides, two second double-axis cylinders 20 are installed on the right rear side of the top of the frame 151 by bolts, and the two second double-axis cylinders 20 are arranged opposite to each other on the left and right sides. The storage box 17 is located between the two second double-axis cylinders 20, and the telescopic rods of the second double-axis cylinders 20 are connected with second blocks 21. The two second blocks 21 slide through the left and right sides of the storage box 17 respectively, and a second distance sensor 22 is installed on the right rear side of the top of the frame 151 by bolts. The first double-axis cylinder 18, the second double-axis cylinder 20 and the second distance sensor 22 are all electrically connected to the controller 14.

[0037] Initially, the telescopic rod of the first double-axis cylinder 18 is in a shortened state, and the telescopic rod of the second double-axis cylinder 20 is in an extended state; the staff can put the spare fruits into the storage box 17, and the second stopper 21 can block the fruits. When the conveyor 155 conveys the fruits to the V-shaped groove 152, there may be a gap, resulting in no fruits between the two adjacent conveying rods 154. At this time, the distance detected by the second distance sensor 22 will become longer, so the second distance sensor 22 will send a signal to the controller 14, and the controller 14 will control the telescopic rod of the second double-axis cylinder 20 to shorten, driving the two second stoppers 21 to move away from each other, and the second stoppers 21 will no longer block the fruits, and the fruits will fall between the two adjacent conveying rods 154. At the same time, the controller 14 controls the telescopic rod of the first double-axis cylinder 18 to extend, driving the two first blocks 19 to move towards each other, and the first blocks 19 can block the remaining fruits in the storage box 17 to prevent too much fruit from falling into the V-shaped groove 152. Then the controller 14 controls the telescopic rod of the second double-axis cylinder 20 to extend, driving the two second blocks 21 to move towards each other, and at the same time, the controller 14 controls the telescopic rod of the first double-axis cylinder 18 to shorten, driving the two first blocks 19 to move away from each other, and the first blocks 19 no longer block the fruits. The fruits roll forward, and the second blocks 21 can block the fruits.

[0038] Reference Fig.12 , also includes an electric guide rail 23, a third electric push rod 24 and an electric suction cup 25. The electric guide rail 23 is installed on the right side of the top of the frame 151 by bolts. The electric guide rail 23 is connected to the left side of the storage box 17. The third electric push rod 24 is installed on the right side of the moving block of the electric guide rail 23 by bolts. The lower end of the telescopic rod of the third electric push rod 24 is connected to the electric suction cup 25.

[0039] The welding position of the packaging film is not beautiful, so the packaging film with welding marks does not need to be used to wrap the fruit. Therefore, when welding the packaging film, the fruit at the corresponding position in the V-shaped groove 152 needs to be taken out; when welding the packaging film, the staff controls the telescopic rod of the third electric push rod 24 to extend, driving the electric suction cup 25 to move downward, and the electric suction cup 25 moves downward to contact the fruit at the corresponding position in the V-shaped groove 152 and suck the fruit. Then, the telescopic rod of the third electric push rod 24 is controlled to shorten, driving the electric suction cup 25 to move upward, and the fruit is taken out from the V-shaped groove 152 to avoid packaging the fruit with the packaging film with welding marks. Then, the electric guide rail 23 is controlled to drive the third electric push rod 24 and the electric suction cup 25 to move backward, and the fruit is moved to the top of the storage box 17. The electric suction cup 25 releases the fruit, and the fruit falls into the storage box 17.

[0040] Reference Fig.13, also includes a vacuum cleaner 26, a vacuum pipe 27 and a connecting frame 28. The vacuum cleaner 26 is installed on the lower front side of the packaging machine 1 by bolts, the vacuum cleaner 26 is connected to the vacuum pipe 27, the connecting frame 28 is connected to the discharge end of the packaging machine 1, the vacuum pipe 27 passes through the top of the connecting frame 28, and the vacuum pipe 27 and the connecting frame 28 are connected.

[0041] The packaging film with welding marks will still enter the packaging machine 1. In order to prevent the packaging film with welding marks from being mixed with the packaged fruits, the packaging film with welding marks needs to be removed; the staff starts the vacuum cleaner 26, and the vacuum cleaner 26 sucks air through the vacuum pipe 27. The packaging film with welding marks will pass under the vacuum pipe 27 when it is sent out from the discharge end of the packaging machine 1. The packaging film with welding marks will be sucked into the vacuum pipe 27 and enter the vacuum cleaner 26 through the vacuum pipe 27 to remove the packaging film with welding marks to prevent the packaging film with welding marks from being mixed with the packaged fruits.

[0042] Reference Fig.14 and Fig.15 , also includes a fourth electric push rod 29 and a thorn needle 30. The fourth electric push rod 29 is installed on the top of the connecting frame 28 by bolts. The telescopic rod of the fourth electric push rod 29 is connected to the thorn needle 30, and the thorn needle 30 slides through the dust suction pipe 27.

[0043] There is air inside the packaging film with traces of welding, which will occupy a larger space inside the vacuum cleaner 26, so the staff can control the extension and retraction of the telescopic rod of the fourth electric push rod 29 to drive the needle 30 to move up and down. When the packaging film with traces of welding enters the vacuum tube 27, the needle 30 can pierce the packaging film with traces of welding to discharge the air inside the packaging film with traces of welding, thereby reducing the space occupied by the packaging film with traces of welding, improving the utilization rate of the internal space of the vacuum cleaner 26, and allowing the vacuum cleaner 26 to accommodate more packaging film with traces of welding. When the telescopic rod of the fourth electric push rod 29 is shortened, the needle 30 will move out of the vacuum tube 27 to prevent the needle 30 from pulling the packaging film with traces of welding.

[0044] Reference Figure 8 , also includes balls 31, the V-shaped groove 152 is evenly spaced and rotatably connected with the balls 31, when the conveying rod 154 conveys the fruit, the fruit will roll on the balls 31, and the balls 31 can prevent the fruit from rubbing against the frame 151 and prevent scratches on the fruit.
