DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0029] Specific implementation examples Figure 1As shown, the present invention relates to a handheld automatic apple bagging machine, comprising a housing 1, a control handle 2 arranged on the housing 1, and a bag spreading mechanism 4, a bag holding mechanism 5, a slitting mechanism 6, a bag top sealing mechanism 7 and a bag bottom sealing mechanism 8 arranged on the housing 1 in sequence along the conveying direction of the apple bag 3, and a closing mechanism 9 matched with the bag bottom sealing mechanism 8 is also arranged on the housing 1. The housing 1 is formed by buckling a plurality of shells.

[0030] The control handle 2 is provided with a driving button, and the housing 1 is provided with a power supply, a controller and a driving motor. The working program of the bagging machine is recorded in the controller. The staff holds the control handle 2 and presses the driving button. The controller drives the bag roller 4, the bag support mechanism 5, the slitting mechanism 6, the bag top sealing mechanism 7, the bag bottom sealing mechanism 8, the closing mechanism 9 and other working parts to cooperate and move according to the working program to realize automatic bagging. In this embodiment, the closing mechanism 9 is located below the bag bottom sealing mechanism 8.

[0031] During operation, the control handle 2 is held to set the discharging end of the bag-supporting mechanism 5 downward, that is, the opening of the opened apple bag 3 output by the bag-supporting mechanism 5 is downward, and the driving button is pressed, and the controller controls the bag-expanding mechanism 4 to convey the apple bag. After the folded apple bag 3 is opened by the bag-supporting mechanism 5, it passes through the slitting mechanism 6, the bag top sealing mechanism 7, the bag bottom sealing mechanism 8 and the closing mechanism 9 under the action of gravity, and the apple bag 3 is put on the apple from top to bottom, and the bag top sealing mechanism 7 seals the part between the slitting mechanism 6 and the top of the apple on the apple bag 3, and the closing mechanism 9 closes and gathers the apple bag at the fruit handle, and the bag bottom sealing mechanism 8 seals the apple bag 3 near the closing part, and the slitting mechanism 6 cuts the apple bag 3 above the bag top sealing mechanism 7. When using the bagging machine to bag apples, there is no need to twist and seal the bag mouth of the apple bag 3 by hand, which effectively reduces the work intensity and improves the work efficiency.

[0032] The bag spreading mechanism 4 includes an apple bag roller 23 and a bag spreading roller pair 24. The width direction of the apple bag 3 is folded. Fig.10 As shown, when the apple bag 3 is on the apple bag roller 23, its edge is folded in a wave line to reduce the width of the apple bag 3, thereby reducing the width of the apple bag roller 23 and the bag unfolding roller 24. The bag unfolding roller 24 is controlled by the controller to rotate, unfold the apple bag 3 from the apple bag roller 23 and convey it to the bag supporting mechanism 5.

[0033] The bag support mechanism 5 includes an outer ring 27 and a bag support block 28. Figure 1-2As shown, the outer ring 27 is connected to the housing 1, and a conical cavity with a larger diameter at the top and a smaller diameter at the bottom is provided on the outer ring 27. The bag-supporting block 28 is located in the conical cavity and is arranged in conjunction with the outer ring 27. A bag-supporting conveying channel is formed between the bag-supporting block 28 and the outer ring 27, and a group of driving rollers 29 are provided on the side wall of the conical cavity. The bag-supporting block 28 is a conical ring mechanism with a larger diameter at the top and a smaller diameter at the bottom and a hole in the middle. The bag-supporting block 28 is inserted between the conical cavities of the outer ring 27, and the outer ring 27 supports the bag-supporting block 28 to prevent the bag-supporting block 28 from falling downward; the bag-supporting block 28 is located in the apple bag 3 to open the apple bag 3, and the driving roller 29 is connected to the driving motor by means of a flexible shaft. The driving roller 29 presses the apple bag 3 on the side wall of the bag-supporting block 28, and the driving roller 29 rotates forward to smoothly convey the apple bag 3 downward in the bag-supporting conveying channel.

[0034] Furthermore, the outer ring 27 and the bag-supporting block 28 are equipped with a magnetic attraction component 30, which is located above the driving roller 29. The bag-supporting block 28 is connected to the outer ring 27 by means of the magnetic attraction component 30. In this embodiment, magnets are respectively inlaid on the outer ring 27 and the bag-supporting block 28. The magnets on the outer ring 27 and the bag-supporting block 28 attract each other and form the magnetic attraction component 30. The magnets are arranged at multiple points along the bag-supporting conveying channel. The bag-supporting block 28 and the outer ring 27 are relatively fixed by means of the mutual attraction between the magnets to prevent the bag-supporting block 28 and the outer ring 27 from falling off during flipping or moving.

[0035] A rubber layer 22 is respectively provided on the side wall of the conical cavity and the side wall of the bag support block 28. The rubber layer 22 covers the surface of the magnetic attraction component 30. The rubber layer 22 increases the distance between the magnets in the magnetic attraction component 30 to reduce the suction force. At the same time, the friction of the outer ring 27 and the bag support block 28 on the apple bag 3 is reduced to prevent the apple bag 3 from being torn.

[0036] When the output length of the apple bag 3 reaches a step distance, the slitting mechanism 6 slits the part of the apple bag 3 on the apple and the initially opened apple bag 3. The housing 1 is provided with a first telescopic rod 31 and a second telescopic rod 32. The first telescopic rod 31 is connected to the outer ring 27, and the second telescopic rod 32 is matched with the upper end of the bag support block 28. The slitting mechanism 6 includes a ring-shaped second heating wire, which is located at the bottom of the conical cavity and fixedly connected to the side wall of the conical cavity. The first telescopic rod 31 contracts to drive the outer ring 27 to rise, and the second telescopic rod 32 extends to limit the position of the bag support block 28, so that the outer ring 27 slightly moves upward relative to the bag support block 28. The second heating wire presses the apple bag 3 against the bag support block 28 and heats it, so that the apple bag 3 is thermally melted and broken. Then the first telescopic rod 31 drives the outer ring 27 and the bag support block 28 to reset.

[0037] While the slitting mechanism 6 is working, the bag top sealing mechanism 7 seals the apple bag 3 above the apples. Fig. 9As shown, the bag top sealing mechanism 7 includes an electric clamp 25 and a first electric heating wire 26. The electric clamp 25 includes a pair of claws 2501 arranged in a V shape. The first electric heating wire 26 is arranged on the working surface of the claw 2501, and the apple bag 3 passes between the working surfaces of the claw 2501. The controller controls the claws 2501 of the electric clamp 25 to close each other, clamp and flatten the apple bag 3, and at the same time, the first electric heating wire 26 is heated to adhere the side walls of the apple bag 3 to form a closed top of the apple bag 3. Since the electric clamp 25 closes the apple bag 3, the apple bag 3 is pulled, and the apple bag 3 can also be prevented from being adhered to the second electric heating wire after hot-melt slitting.

[0038] At the same time, the closing mechanism 9 works. Figure 3 , Figure 4 As shown, the closing mechanism 9 comprises a box body 18 with a closing wire roller 17, a second conveying roller group 20 and a clamping roller group 21 sequentially arranged on the box body 18 along the conveying direction of the closing wire 19, a through hole for the apple bag 3 to pass through is arranged on the box body 18, a guide groove 1801 for the closing wire 19 is opened on the side wall of the through hole, the clamping roller group 21 is located at the entrance end of the guide groove 1801, and the closing wire roller 17 is fixedly connected to the end of the guide groove 1801. The closing mechanism 9 is located at the apple handle. When closing the apple bag 3, the second conveying roller group 20 is reversed to recycle the closing wire 19 in the guide groove 1801 to the closing wire roller 17, so that the closing wire 19 forms a ring structure with a cross-sectional area smaller than the cross-sectional area of ​​the through hole in the through hole, thereby closing the opened apple bag 3 and making the lower end of the apple bag 3 gather and close into a structure similar to an hourglass. After the closing mechanism 9 completes the closing work, the electric clamping jaws 25 open.

[0039] like Figure 5 , Figure 6 , Figure 7 As shown, the bag bottom sealing mechanism 8 includes a sealing strip roller 11, a first conveying roller group 12, a winding roller group 13 and a cutting knife 14 which are sequentially arranged along the conveying direction of the sealing strip 10. The winding roller group 13 includes a first shaping roller 15 and a second shaping roller 16. The first shaping roller 15 is respectively provided with an inner guide groove 1501 and an outer guide groove 1502. The second shaping roller 16 is matched with the outer guide groove 1502. The sealing strip 10 passes through the outer guide groove 1502 and the inner guide groove 1501 in sequence and then spirally coils around the waist of the hourglass-shaped apple bag 3 to seal. The first conveying roller group 12 rotates to unfold and convey the sealing strip 10 on the sealing strip roller 11. When the sealing strip 10 passes through the outer guide groove 1502 on the first shaping roller 15, the second shaping roller 16 squeezes the sealing strip 10 respectively, so that the sealing strip 10 is bent and gradually coiled around the closing position of the apple bag 3, as shown in FIG. Figure 8As shown, during the spiraling process, the end of the sealing strip 10 passes through the inner guide groove 1501, and the inner guide groove 1501 further shapes the sealing strip 10. The spirally coiled sealing strip 10 binds the lower end of the apple bag 3 to prevent the lower end of the apple bag 3 from opening. Then the cutting knife 14 moves to cut the sealing strip 10. The spirally coiled sealing strip 10 is relatively fixed to the apple bag 3 under the friction between the apple bag 3 and will not fall off.

[0040] The cutting knife 14 is moved by means of an electric telescopic rod.

[0041] The driving roller 29 on the outer ring 27 reverses to move the apple bag 3 in the bag support conveying channel upward to prevent the apple bag 3 from sticking to the second heating wire. Then the driving roller 29 cooperates with the bag unfolding roller 24 to convey the apple bag 3 outward by a step length.

[0042] In this embodiment, the closing wire 19 is a steel bar. In the closing mechanism 9, the second conveying roller group 20 rotates forward to convey the closing wire 19 to the guide groove 1801. The clamping roller group 21 guides the closing wire 19, and the closing wire 19 is pressed into the guide groove 1801 again to prepare for closing the apple bag 3.
