[0019] The following describes exemplary embodiments of the present invention in conjunction with specific circumstances:

[0020] Please refer to Figures 1-3 The present invention provides a fruit packaging mechanism, including a packaging support. Along the fruit conveying direction, the packaging support is provided with a conveying device, a mouth-opening transfer device, and a mouth-closing and cutting device for conveying the fruit to a designated position. The mouth-opening transfer device is used to open the packaging bag 52 and transfer it to the mouth-closing and cutting point. The mouth-closing and cutting device is used to close the packaging bag 52 and cut it neatly. In this embodiment, the conveying device includes a conveyor belt 91 and a drive motor 93. The drive motor 93 can drive the conveyor belt 91 to rotate. A conveying baffle 92 is provided on the conveyor belt 91.

[0021] A supporting lifting device is provided below the conveying device. The supporting lifting device includes a lifting bracket 1. A supporting module is slidably mounted inside the lifting bracket 1. The supporting module includes a supporting bracket 2. A first roller 3 and a second roller 4 are rotatably mounted on the supporting bracket 2.

A transmission gear 7 is fixed to the left end of the first rotating shaft 5. A transmission rack 8 is fixed to the lifting bracket 1. The transmission gear 7 meshes with the transmission rack 8. A guide plate 9 is fixed to the supporting bracket 2. The guide plate 9 is located behind the first roller 3. An inclined guide block 10 is fixed to the guide plate 9.

[0022] In this embodiment, the first roller 3 rotates and, with the cooperation of the guide block 10, guides the bottom of the packaging bag 52 to move between the first roller 3 and the second roller 4. Then, the height of the first roller 3 and the second roller 4 is raised, and then slowly lowered when the fruit falls, so as to reduce the height difference when the fruit falls and reduce the probability of damage to the fruit surface.

[0023] A sliding guide rail is vertically laid inside the lifting bracket 1, and a sliding limit block is slidably fixed on the sliding guide rail. The support bracket 2 is detachably fixed on the sliding limit block.

[0025] In this embodiment, the lifting drive motor 14 is used to adjust the height of the support module. During adjustment, the first roller 3 is driven by the cooperation of the transmission rack 8 and the transmission gear 7.

[0026] Working principle description: The packaging bag 52 is pulled above the guide block 10 and the first roller 3 by the opening transfer device. The lifting transmission motor 14 is started. Under the action of the lifting transmission motor 14, the support bracket 2 moves upward. At the same time, the first roller 3 rotates clockwise under the action of the transmission rack 8. When the packaging bag 52 contacts the first roller 3, the bottom of the packaging bag 52 is guided between the first roller 3 and the second roller 4. Then the lifting transmission motor 14 continues to rotate, driving the first roller 3 and the second roller 4 to the designated height, shortening the height difference between the bottom of the packaging bag 52 and the conveyor belt 91.

[0027] With the help of the opening-opening transfer device, the bag opening is opened, and under the action of the external conveyor belt 91, the fruit falls through the bag opening into the packaging bag 52. The first roller 3 and the second roller 4 can receive the fruit falling into the packaging bag 52. During the falling process, the number of fruits in the packaging bag 52 increases in turn. The lifting transmission motor 14 is started to drive the first roller 3 and the second roller 4 on the support bracket 2 to move slowly downward until a certain number of fruits are received in the packaging bag 52.

[0028] Please refer to Figures 4-9 The opening transfer device includes a first sliding rod group 16, on which a bag support module and an opening module are slidably mounted; The support module includes a support bracket 17 slidably disposed on a first sliding rod group 16, a second sliding rod group 18 disposed inside the support bracket 17, an adsorption bracket 19 slidably disposed on the second sliding rod group 18, and a first adsorption clamping module and a second adsorption clamping module symmetrical to the first adsorption clamping module disposed on the adsorption bracket 19. The first adsorption clamping module includes a first adsorption support frame 20, a first rotary cylinder 21 is horizontally arranged on the front side of the first adsorption support frame 20, a first clamping piece 22 is fixed on the cylinder body of the first rotary cylinder 21, and a first industrial suction cup 23 is arranged on the first adsorption support frame 20 at a position opposite to the first clamping piece 22.

[0029] In this embodiment, when a certain number of fruits fall into the packaging bag 52, the first industrial suction cup 23 and the second industrial suction cup 27 of the opening transfer device can adsorb the packaging bag 52. After adsorption, the first clamping piece 22 and the second clamping piece 26 limit one side of the packaging bag 52 between the first clamping piece 22 and the first industrial suction cup 23, and the second clamping piece 26 and the second industrial suction cup 27, while the other side is limited by the limiting hook 37. The opening operation of the packaging bag 52 can be quickly achieved through the above operation.

[0030] A vibration cylinder 28 is vertically downwardly mounted on the top of the support bracket 17, and the piston rod of the vibration cylinder 28 is fixedly connected to the adsorption bracket 19. A distance adjustment cylinder 29 is mounted on the front side of the first sliding rod, and the slider of the distance adjustment cylinder 29 is fixedly connected to the support bracket 17. An elastic guide module is mounted on the top of the support bracket 17. The elastic guide module includes an elastic guide frame 30, and two guide posts 31 are fixed on the elastic guide frame 30. The guide posts 31 are slidably inserted into the inside of the guide sleeve 32, and the guide sleeve 32 is fixed to the top of the adsorption bracket 19. A buffer spring 33 is mounted on the guide post 31, and the buffer spring 33 is located between the elastic guide frame 30 and the adsorption bracket 19.

[0031] In this embodiment, the vibration cylinder 28 can generate high-frequency vibration to prevent the fruit from accumulating and bridging at the bag opening during the falling process, while the distance adjustment cylinder 29 can adjust the distance between the first adsorption clamping module, the second adsorption clamping module and the bag support frame 34, thereby realizing the opening operation of the packaging bag 52. The elastic guide frame 30 is elastically limited on the guide sleeve 32 by the guide post 31, and the fruit can be elastically dropped into the packaging bag 52 through the elastic guide frame 30 to reduce damage.

[0032] The bag support module includes a bag support frame 34, which is slidably mounted on a first sliding rod assembly 16. Two inclined bag hanging rods 35 are provided on the bag support frame 34. A limiting rod 36 is rotatably mounted at the bottom of the bag support frame 34, and two limiting hooks 37 are provided on the limiting rod 36. A limiting adjustment cylinder 38 is hinged to the top of the bag support frame 34, and the piston rod of the limiting adjustment cylinder 38 is hinged to an arc-shaped guide plate 39, which is fixed to the limiting rod 36. A compression adjustment plate 40 is sleeved on the bag hanging rod 35, and a counterweight 41 is provided on the compression adjustment plate 40.

[0033] In this embodiment, the limiting adjustment cylinder 38 can make the limiting hook 37 abut against the left inner wall of the packaging bag 52, thereby cooperating with the opening module to realize the opening operation; the bag hanging rod 35 is set in an inclined position, and under the action of the squeezing adjustment plate 40, the packaging bag 52 on the bag hanging rod 35 can always move downward and fit against the left side of the bag hanging rod 35.

[0034] A transfer module is provided between the first adsorption support frame 20 and the second adsorption support frame 24. The transfer module includes a transfer bracket 42, which is movably disposed inside the adsorption support frame 19 and slidably disposed on a third sliding rod assembly 43. The third sliding rod assembly 43 is fixed between the first transfer support frame 44 and the second transfer support frame 45. A first transfer clamping cylinder 46 is hinged inside the transfer bracket 42, and the piston rod of the first transfer clamping cylinder 46 is hinged to a transfer clamping plate 47. The top of the transfer clamping plate 47 is rotatably disposed inside the transfer bracket 42. An alignment through hole 48 is provided on the transfer clamping plate 47. A second transfer clamping cylinder 49 is horizontally disposed on the top of the transfer bracket 42. A clamping ball 50 that matches the alignment through hole 48 is fixed on the piston rod of the first transfer clamping cylinder 46. A transfer cylinder 51 is horizontally disposed on the second transfer bracket 42, and the piston rod of the transfer cylinder 51 is fixedly connected to the transfer bracket 42.

[0035] In this embodiment, the transfer module can limit the opening of the fruit-filled packaging bag 52 and transfer it to a designated position. Specifically, the piston rod of the transfer cylinder 51 extends to bring the clamping ball 50 against the packaging bag 52. Then, the piston rod of the first transfer clamping cylinder 46 is shortened and the piston rod of the second transfer clamping cylinder 49 is extended. The transfer clamping plate 47 brings the packaging bag 52 against the upper alignment through hole 48 and the clamping ball 50 to limit and close the opening. Then, the transfer cylinder 51 is activated to transfer the closed packaging bag 52 to the designated position.

[0036] Working principle description: A certain number of packaging bags 52 are hung on the bag hanging rod 35. The distance adjustment cylinder 29 is activated to move to the left, so that the first industrial suction cup 23 and the second industrial suction cup 27 abut against the right outer wall of the packaging bag 52. The external vacuum generator is activated to adsorb the right outer wall of the packaging bag 52. The first rotary cylinder 21 and the second rotary cylinder 25 are activated, so that the first clamping plate 22 and the second clamping plate 26 clamp the right inner wall of the packaging bag 52.

[0037] Then, the distance adjustment cylinder 29 is activated again to move to the right to the specified distance, so that the packaging bag 52 is opened. At this time, the piston rod of the limit adjustment cylinder 38 is extended, which drives the limit rod 36 to rotate, so that the limit hook 37 abuts against the left inner wall of the packaging bag 52.

[0038] The conveyor belt 91 transports a certain amount of fruit into the packaging bag 52. When fruit falls onto the elastic guide frame 30, it is cushioned by the elastic guide frame 30 and falls into the packaging bag 52, which can reduce fruit damage. During the fruit transport and falling process, the vibrating cylinder 28 can generate high-frequency vibration to drive the adsorption bracket 19 to vibrate up and down at high frequency, thereby causing the fruit bag to shake up and down at high frequency when the fruit falls, preventing the fruit from accumulating and bridging at the bag opening during the falling process.

[0039] After filling is completed, the piston of the limiting adjustment cylinder 38 shortens, causing the limiting rod 36 to rotate, and the limiting hook 37 releases the limiting of the packaging bag 52. At this time, the right side of the packaging bag 52 is still limited by the first clamping piece 22 and the second clamping piece 26. The piston rod of the transfer cylinder 51 extends and brings the clamping ball 50 against the packaging bag 52. The piston rod of the first transfer clamping cylinder 46 shortens and causes the transfer clamping plate 47 to rotate clockwise. The transfer clamping plate 47 contacts the packaging bag 52. The piston rod of the second transfer clamping cylinder 49 extends and the transfer clamping plate 47 brings the packaging bag 52 against the upper alignment through hole 48 and the clamping ball 50 for limiting and closing. Then, the transfer cylinder 51 is activated to transfer the closed packaging bag 52 to the designated position.

[0043] In this embodiment, the horizontal position adjusting cylinder 74 can drive the slider 56 to slide on the conveying guide rail 55, which can move the sealed packaging bag 52 to the cutting head for easy cutting.

[0044] The closing extrusion module includes a first closing extrusion bracket 75 and a second closing extrusion bracket 76 adapted to the first closing extrusion bracket 75. The first closing extrusion bracket 75 is provided with a plurality of first guide rollers 77, and a first conveying extrusion belt 79 is wound on the first guide rollers 77. The second closing extrusion bracket 76 is provided with a plurality of second guide rollers 78, and a second conveying extrusion belt 80 is wound on the second guide rollers 78. A transmission motor 81 is vertically downward on the closing frame 53. The rotor of the transmission motor 81 drives the first conveying extrusion belt 79 to rotate along the first guide roller 77. The first conveying extrusion belt 79 is attached to the second conveying extrusion belt 80. Material photoelectric sensor gates 82 are provided on the first closing extrusion bracket 75 and the second closing extrusion bracket 76. In this embodiment, the transfer module can transport the packaging bag 52 between the first conveyor extrusion belt 79 and the second conveyor extrusion belt 80, thereby limiting and transporting the packaging bag 52 to the corresponding closing claw for easy closing operation. The material photoelectric sensor gate 82 is used to detect whether a packaging bag 52 has arrived.

[0045] The sealing module includes a sealing tape 85 and a cutting head 83, and an elastic pressure block 84 is hinged to the sealing frame 53 at a position opposite to the sealing tape 85 and the cutting head 83.

[0046] In this embodiment, after the packaging bag 52 is closed by the closing claw, it moves between the sealing tape 85 cutting head 83 and the elastic pressure block 84 under the action of the transfer module. The sealing tape 85 will stick to the closing part of the packaging bag 52. When the closing part of the packaging bag 52 moves to the cutting part, the elastic pressure block 84 will apply the sealing tape 85 to the sealing tape 85 cutting head 83 under the action of the spring force, thereby cutting the sealing tape 85.

[0047] The cutting module includes a cutting frame 87, a cutting cylinder 88 is hinged inside the cutting frame 87, a cutting push rod 89 is hinged to the piston rod of the cutting cylinder 88, and a packaging bag 52 cutting blade is fixed on the cutting push rod 89.

[0048] In this embodiment, a sealing belt conveyor 86 is provided on the right side of the cutting module. Both the sealing belt conveyor 86 and the sealing module are existing technologies. You can refer to the sealing machine for plastic bags in supermarkets. The working principle will not be described in detail here. The cutting module can perform cutting operations on the position above the closing part of the packaging bag 52, thereby improving production efficiency.

[0049] Working principle description: Under the action of the transfer module, the packaging bag 52 is clamped and transferred between the first conveyor extrusion belt 79 and the second conveyor extrusion belt 80, so as to facilitate the extrusion and limiting transfer of the packaging bag 52 between the first closing claw 66 and the second closing claw 67, and between the third closing claw 70 and the fourth closing claw 71.

[0050] When the packaging bag 52 moves between the corresponding closing claws, the piston rods of the first closing cylinder 64, the second closing cylinder 65, the third closing cylinder 68, and the fourth closing cylinder 69 are all extended, and the upper and lower parts of the packaging bag 52 can be quickly closed through the corresponding closing claws.

[0051] After the sealing is completed, the packaging bag 52 continues to move to the right under the action of the transfer module, while the piston rod of the horizontal position adjusting cylinder 74 shortens, causing the sealing claw to move synchronously with the transfer cylinder 51. At this time, the sealing tape 85 is guided to the right side of the first sealing compression bracket 75 and the second sealing compression bracket 76. As the packaging bag 52 continues to move to the right, the sealing tape 85 contacts and sticks to the sealing end of the packaging bag 52.

[0052] When the closing end of the packaging bag 52 moves to the cutting end, the elastic pressure block 84, under the action of the spring force, will apply the sealing tape 85 to the sealing tape 85 cutting head 83, thereby cutting the sealing tape 85.

[0053] Subsequently, the height adjustment cylinder 62 drives the first closing claw 66 and the second closing claw 67 to move upward, tightening the packaging bag 52 and reserving a cutting position for the cutting blade of the packaging bag 52.

[0054] The piston rod of the cutting cylinder 88 is extended, causing the cutting blade of the packaging bag 52 to extend out from the cutting frame 87 and act on the reserved cutting position of the packaging bag 52 to achieve flat cutting. After cutting, the closing claw releases the restriction on the packaging bag 52, and the packaging bag 52 falls to the designated position.

[0055] Overall workflow description of the equipment: A certain number of packaging bags 52 are hung on the bag hanging rod 35. The distance adjustment cylinder 29 is activated to move to the left, so that the first industrial suction cup 23 and the second industrial suction cup 27 abut against the right outer wall of the packaging bag 52. The external vacuum generator is activated to adsorb the right outer wall of the packaging bag 52. The first rotary cylinder 21 and the second rotary cylinder 25 are activated, so that the first clamping plate 22 and the second clamping plate 26 clamp the right inner wall of the packaging bag 52.

[0056] Then, the distance adjustment cylinder 29 is activated again to move to the right to the specified distance, opening the packaging bag 52. At this time, the piston rod of the limit adjustment cylinder 38 extends, driving the limit rod 36 to rotate, causing the limit hook 37 to abut against the left inner wall of the packaging bag 52. When the packaging bag 52 is open, its bottom is above the guide block 10 and the first roller 3. The lifting drive motor 14 is activated, and under the action of the lifting drive motor 14, the support bracket 2 moves upward. At the same time, the first roller 3 rotates clockwise under the action of the transmission rack 8. When the packaging bag 52 contacts the first roller 3, the bottom of the packaging bag 52 is guided between the first roller 3 and the second roller 4. Then, the lifting drive motor 14 continues to rotate, driving the first roller 3 and the second roller 4 to the specified height, shortening the height difference between the bottom of the packaging bag 52 and the conveyor belt 91.

[0057] The conveyor belt 91 transports a certain amount of fruit into the packaging bag 52. When fruit falls onto the elastic guide frame 30, it is cushioned by the elastic guide frame 30 and falls into the packaging bag 52, which can reduce fruit damage. During the fruit transport and falling process, the vibrating cylinder 28 can generate high-frequency vibration to drive the adsorption bracket 19 to vibrate up and down at high frequency, thereby causing the fruit bag to shake up and down at high frequency when the fruit falls, preventing the fruit from accumulating and bridging at the bag opening during the falling process.

[0058] When the fruit falls into the packaging bag 52, the first roller 3 and the second roller 4 can catch the fruit falling into the packaging bag 52. During the falling process, the number of fruits in the packaging bag 52 increases in turn. The lifting transmission motor 14 is started to drive the first roller 3 and the second roller 4 on the support bracket 2 to move slowly downward until the packaging bag 52 has caught a certain number of fruits.

[0059] After filling, the piston of the limiting adjustment cylinder 38 shortens, causing the limiting rod 36 to rotate, and the limiting hook 37 releases the limiting of the packaging bag 52. At this time, the right side of the packaging bag 52 is still limited by the first clamping piece 22 and the second clamping piece 26. The piston rod of the transfer cylinder 51 extends, causing the clamping ball 50 to abut against the packaging bag 52. The piston rod of the first transfer clamping cylinder 46 shortens, causing the transfer clamping plate 47 to rotate clockwise. The transfer clamping plate 47 contacts the packaging bag 52. The piston rod of the second transfer clamping cylinder 49 extends, and the transfer clamping plate 47 abuts the packaging bag 52 against the upper alignment through hole 48 and the clamping ball 50 for limiting and closing. Then, the transfer cylinder 51 is activated, and the closed packaging bag 52 is transferred to the corresponding closing claws via the first conveyor extrusion belt 79 and the second conveyor extrusion belt 80.

[0060] When the packaging bag 52 moves between the corresponding closing claws, the piston rods of the first closing cylinder 64, the second closing cylinder 65, the third closing cylinder 68, and the fourth closing cylinder 69 are all extended, and the upper and lower parts of the packaging bag 52 can be quickly closed through the corresponding closing claws.

[0061] After the sealing is completed, the packaging bag 52 continues to move to the right under the action of the transfer module, while the piston rod of the horizontal position adjusting cylinder 74 shortens, causing the sealing claw to move synchronously with the transfer cylinder 51. At this time, the sealing tape 85 is guided to the right side of the first sealing compression bracket 75 and the second sealing compression bracket 76. As the packaging bag 52 continues to move to the right, the sealing tape 85 contacts and sticks to the sealing end of the packaging bag 52.

[0062] When the closing end of the packaging bag 52 moves to the cutting end, the elastic pressure block 84, under the action of the spring force, will apply the sealing tape 85 to the sealing tape 85 cutting head 83, thereby cutting the sealing tape 85.

[0063] Subsequently, the height adjustment cylinder 62 drives the first closing claw 66 and the second closing claw 67 to move upward, tightening the packaging bag 52 and reserving a cutting position for the cutting blade of the packaging bag 52.

[0064] The piston rod of the cutting cylinder 88 is extended, causing the cutting blade of the packaging bag 52 to extend out from the cutting frame 87 and act on the reserved cutting position of the packaging bag 52 to achieve flat cutting. After cutting, the closing claw releases the restriction on the packaging bag 52, and the packaging bag 52 falls to the designated position.
