[0018] By setting up a bag loading component, the second suction cup is driven to descend by the second telescopic cylinder during clamping, and the rice packaging bag inside the placement box is adsorbed and then rises to the pneumatic clamp. After the pneumatic clamp is clamped, the rice packaging bag is positioned in a vertical state to just below the unloading component and the bag opening component through the rotating part, thereby realizing automatic bag loading; when the pneumatic clamp is worn after long-term use, the rice packaging bag tends to slide down after clamping due to loose clamping, and the side of the anti-skid gear in contact with the rice packaging bag is subjected to a downward force, and the anti-skid gear tends to rotate.

At this time, the first suction cups on both sides open the bag opening of the rice packaging bag, and at the same time, the mounting plate drives the connecting rod to rotate back with the first threaded rod as the axis. When the opening rod rotates back, it moves down and inserts into the bag opening, and with the rotation of the connecting rod, the bag opening is further opened from the inside to the outside, and the bag opening is fully opened to avoid rice spilling during feeding.

At this time, the pressure rod on one side is pressed to drive the corresponding sliding rod to slide downward, and the sliding rod pushes the first piston connected to one end downward, so that the pressure in the chamber on one side of the partition increases. When the two pressure sensors detect that the pressure difference in the chambers on both sides of the partition exceeds a certain range, the second electromagnet is immediately energized in the reverse direction, and the mobile valve is pushed out by the repulsive force to close the feeding, and the card bead is slid into the limit hole to limit the mobile valve to avoid large-scale leakage.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to solve the technical problem that rice bags still need to be opened manually when they are packed, which reduces the efficiency of rice packing, such as Figure 1-Figure 4 As shown, the following preferred technical solutions are provided:

[0033] A rice bagging and rice dispensing device for food processing comprises a support 1 and a rice dispensing drum 2 fixedly connected to the support 1, the rice dispensing drum 2 is used to hold a certain amount of rice, a feeding assembly 3 is fixedly connected to the bottom surface of the rice dispensing drum 2, a certain amount of rice is transported to a rice packaging bag by opening and closing the feeding assembly 3, a bag opening assembly 4 is fixedly connected to the lower ends of the side walls on both sides of the feeding assembly 3, the bag opening assembly 4 is arranged to open the bag mouth of the rice packaging bag and further stretch it open to avoid leakage when the rice is filled by the feeding assembly 3, and a detection assembly 5 is fixedly arranged below the bag opening assembly 4, the detection assembly 5 is used to detect whether the rice packaging bag is filled with rice. When the rice packaging bag is tilted, the unloading port of the unloading component 3 is closed and the unloading component 3 is limited. An upper bag component 6 is fixedly installed on the side of the detection component 5. The upper bag component 6 is used to grab the placed rice packaging bag to the unloading position. A pressure component 7 is fixedly connected to the side wall of the unloading component 3. The pressure component 7 is connected to the detection component 5 through a pipeline. When the rice packaging bag is tilted, the loaded rice is accumulated to one side so that the detection component 5 is pressurized. When the detection component 5 is pressurized, the pressure of the pressure component 7 is increased through the pipeline. After the pressure component 7 releases the pressure, it is used to release the limiting effect on the unloading component 3.

[0034] When in use, first a certain amount of rice is conveyed into the rice dispensing barrel 2, and then the horizontally stacked rice packaging bags are adsorbed to the clamping position through the bag upper assembly 6. After the rice packaging bags are clamped from both sides, the bag upper assembly 6 is rotated 90 degrees in the direction of the lower material assembly 3, so that the rice packaging bags are positioned in a vertical state directly below the lower material assembly 3. During the rotation process, the clamping parts on both sides approach each other, so that the rice packaging bag forms an opening. After the rice packaging bag is positioned, the bag opening assembly 4 approaches and adsorbs the rice packaging bag, and then moves outward to further pull the rice packaging bag open. At the same time, the other side of the bag opening assembly 4 is inserted into the rice packaging bag to form a support from the inside, thereby completing the automatic bagging and opening of the rice packaging bag. When bagging rice, there is no need to manually install the packaging bag to the lower material position, thereby improving the rice bagging efficiency. During bagging, the lower material assembly 3 forms a passage with the inside of the rice dispensing barrel 2, and the lower material assembly 3 is closed after being opened for a period of time, thereby completing the packaging of a certain amount of rice.

[0035] During the rice bagging process, the clamping parts on the upper bag assembly 6 can prevent the rice packaging bag from sliding down. When the rice packaging bag is still tilted, the rice loaded will tend to one side. The pressure degree on both sides of the bottom of the packaging bag is detected by the detection assembly 5. When the pressure difference on both sides of the bottom of the rice packaging bag exceeds a certain range, it is determined that it is tilted. At this time, the unloading assembly 3 is immediately closed and reaches the limit position to avoid large-scale leakage of rice and cause unnecessary losses. When the detection assembly 5 is pressurized, the connecting pipe of the pressure assembly 7 is pressurized. After the pressure is increased, the valves at both ends of the pipe are closed to maintain the pressure. After the tilting fault of the rice packaging bag is eliminated, the rice packaging bag is positioned below the unloading assembly 3 again. At this time, the valve close to the side of the pressure assembly 7 is opened to release the pressure, and the limit of the unloading assembly 3 is released through the pressure assembly 7. At the same time, the unloading assembly 3 is powered on and turned on.

[0036] The feeding assembly 3 includes a feeding pipe 31, a movable valve 32, a first electromagnet 33 and a second electromagnet 34. The feeding pipe 31 passes through and is fixedly connected to the bottom surface of the rice mixing barrel 2. A sliding hole 311 is provided on the side wall of the feeding pipe 31. The movable valve 32 is slidably connected inside the sliding hole 311. A connecting hole 321 is provided on the top surface of the movable valve 32. When the connecting hole 321 is moved to the inside of the feeding pipe 31, a passage is formed between the feeding assembly 3 and the inside of the rice mixing barrel 2. A card bead 322 is embedded on the side wall of the movable valve 32. The first electromagnet 33 is fixedly connected to one end of the movable valve 32. The second electromagnet 34 is fixedly connected to the side wall of the bracket 1. The second electromagnet 34 can attract or repel the first electromagnet 33 by energizing in forward and reverse directions, thereby controlling the moving direction of the movable valve 32, and further controlling whether the feeding assembly 3 is connected to the rice mixing barrel 2.

[0037] The bag opening assembly 4 includes connecting pieces 41 symmetrically fixedly connected to the lower ends of the outer walls on both sides of the feeding tube 31, and each connecting piece 41 is fixedly connected to a first telescopic cylinder 42 on the side wall, and each movable end of the first telescopic cylinder 42 is fixedly connected to a mounting plate 43, and the mounting plate 43 is driven to move by the first telescopic cylinder 42, and a connecting frame 44 is symmetrically penetrated and rotatably connected to the upper side wall of each mounting plate 43, and a connecting rod 45 is sleeved on the outer wall of each connecting frame 44 away from the mounting plate 43. The connecting rod 45 can slide up and down along the outer wall of one side of the connecting frame 44, and the two connecting pieces located on the same side of the feeding tube 31 The connecting frame 44 and the two connecting rods 45 are arranged in a W shape, and a spreading rod 46 is fixedly connected to the bottom surface of one end of each connecting rod 45, and a first threaded rod 47 is fixedly connected to the top surface of the other end of each connecting rod 45. Each first threaded rod 47 is threadedly connected to the bottom surface of the discharge pipe 31. When the first telescopic cylinder 42 drives the mounting plate 43 to move, the connecting rod 45 can be driven by the connecting frame 44 to rotate around the first threaded rod 47 as the axis, so that the spreading rod 46 rises when it rotates outward, and descends when it rotates inward to insert into the opening of the rice packaging bag, so that the bag opening of the rice packaging bag is pulled open to both sides and is spread and limited from the inside.

[0038] A plurality of first suction cups 48 are fixedly connected to the side wall at the lower end of each mounting plate 43. The first suction cups 48 can be driven to move when the mounting plate 43 moves, and the rice packaging bag is sucked from both sides and then retracted, so as to open the bag mouth of the rice packaging bag.

[0039] Specifically, after the rice packaging bag is positioned below the blanking assembly 3, the first telescopic cylinder 42 is started to push the mounting plate 43 forward. When the mounting plate 43 moves forward, the connecting rod 45 is driven by the connecting frame 44 to rotate outward with the first threaded rod 47 as the axis, so that the opening rod 46 connected to the bottom surface of the connecting rod 45 moves up a certain distance when it rotates outward. At the same time, when the mounting plate 43 moves forward, it can also drive the first suction cup 48 to approach the rice packaging bag and adsorb it. Then the first telescopic cylinder 42 moves in the opposite direction to drive the mounting plate 43 to move back. At this time, the first suction cups 48 on both sides open the bag opening of the rice packaging bag. At the same time, the mounting plate 43 drives the connecting rod 45 to rotate back with the first threaded rod 47 as the axis. When the opening rod 46 rotates back, it moves down and inserts into the bag opening, and as the connecting rod 45 The rotation of the rod 45 further stretches the bag opening from the inside to the outside, so that the bag opening can be fully opened to avoid rice spilling when unloading, and no manual operation is required, so it is convenient to use. After the bag opening of the rice packaging bag is opened, the first electromagnet 33 is energized in a direction, and the second electromagnet 34 is energized in the forward and reverse directions periodically. When energized in the forward direction, the first electromagnet 33 and the second electromagnet 34 have different polarities, which attract the movable valve 32 to move so that the part with the connecting hole 321 enters the inside of the unloading pipe 31. At this time, the rice mixing barrel 2 and the unloading component 3 form a passage. After a certain amount of rice is transported to the packaging bag, the second electromagnet 34 is energized in the reverse direction. At this time, the first electromagnet 33 and the second electromagnet 34 have the same polarity, and the movable valve 32 is reset by the repulsive force to block the unloading pipe 31.

[0040] In order to solve the technical problem that when the rice packaging bag is tilted during the rice filling process, no corresponding protective measures are set, which may cause unnecessary losses due to large-scale leakage of rice, such as Figure 5-Figure 8 As shown, the following preferred technical solutions are provided:

[0041] The detection component 5 includes a mounting platform 51 fixedly installed on the ground directly below the bag opening component 4, a vertical plate 52 is fixedly connected to the top surface of the mounting platform 51, vertical slide grooves 521 are symmetrically opened on the side walls of the vertical plate 52, a pressure rod 53 is slidably connected in each vertical slide groove 521, and a detection box 54 is fixedly connected to the bottom surface of the mounting platform 51.

[0042] The detection box 54 includes a box body 541, and a partition 542 is fixedly connected to the inner wall of the box body 541, and the interior of the box body 541 is divided into two chambers by the partition 542. The side walls on both sides of the partition 542 are sealed and slidably connected to the inner wall of the box body 541. A sliding rod 544 is fixedly connected to the top surface of each first piston 543. The sliding rod 544 penetrates and slides through the box body 541 and the top wall of the mounting platform 51. The top ends of the two sliding rods 544 are respectively fixedly connected to the bottom surfaces of the two pressure rods 53. The bottom surfaces of the two pressure rods 53 and the top surface of the mounting platform 51 are elastically connected by springs 545, and the two sliding rods 544 are respectively penetrated and arranged on the two springs 545. 5, when the rice packaging bag is not tilted, the two pressure rods 53 only bear the pressure caused by the expansion of the packaging bag, which is not enough to overcome the elastic force of the spring 545. Pressure sensors 546 are fixedly installed on the outer walls of both sides of the box body 541 for detecting the pressure in the chambers on both sides of the partition 542. A pressure pipe 547 is fixedly connected to the outer wall of the box body 541. The pressure pipe 547 is a three-way structure. One end of the pressure pipe 547 is connected to the pressure assembly 7, and the other two ends of the pressure pipe 547 are respectively connected to the chambers on both sides of the partition 542. Each connecting end of the pressure pipe 547 is installed with a solenoid valve 548. After the pressure pipe 547 is pressurized, the solenoid valve 548 is closed to maintain the pressure.

[0043] The pressure assembly 7 includes a limit block 71 fixedly connected to the side wall of the discharge pipe 31, and a limit hole 711 is opened on the side wall of the limit block 71. The movable valve 32 is limited by the clamping bead 322 embedded on the side wall of the movable valve 32 and the limit hole 711 opened on the limit block 71. One end of the limit hole 711 is fixedly connected to a plunger cylinder 72, and one end of the plunger cylinder 72 is connected to the inside of the limit hole 711. A second piston 73 is slidably connected to the inside of the plunger cylinder 72. When the solenoid valve 548 near one end of the pressure assembly 7 is opened, the pressure released by the pressure tube 547 pushes the second piston 73 to move and push out the clamping bead 322, thereby releasing the limit on the movable valve 32.

[0044] Specifically, initially, the solenoid valve 548 near one end of the pressure assembly 7 is in a closed state, and the solenoid valve 548 near one end of the box 541 is in an open state. When the rice packaging bag is tilted, the rice is gathered to one side. At this time, the pressure rod 53 on one side is pressed to drive the corresponding slide rod 544 to slide downward. The slide rod 544 pushes the first piston 543 connected to one end thereof downward, so that the pressure in the chamber on one side of the partition 542 increases. The two pressure sensors 546 detect that the pressure difference in the chambers on both sides of the partition 542 exceeds a certain value. When the bag is within the specified range, the second electromagnet 34 is immediately energized in the reverse direction, and the movable valve 32 is pushed out by the repulsive force to close the material discharge, and the card bead 322 is slid and stuck in the limiting hole 711, so as to limit the movable valve 32 and avoid large-scale leakage. At the same time, the solenoid valve 548 near one end of the box body 541 is closed to maintain the pressure inside the pressure tube 547. After the fault is eliminated and the packaging bag is re-clamped, the solenoid valve 548 near one end of the pressure assembly 7 is opened to release the pressure, and the second piston 73 is pushed to move so that the card bead 322 is pushed out of the limiting hole 711.

[0045] In order to solve the technical problems that rice bagging needs to be done manually, long-term repeated operations may lead to improper clamping, and the clamping components may be worn after long-term use, and the rice packaging bags may be tilted during the rice filling process due to loose clamping.

[0049] Specifically, the rotary arm 653 is initially in a vertical state. During clamping, the second suction cup 64 is first driven downward by the second telescopic cylinder 63 to absorb the rice packaging bag inside the placement box 61 and then rise to the pneumatic clamp 66. The pneumatic clamp 66 clamps the horizontally placed rice packaging bag from both sides, and then the rotary motor 651 drives the rotary arm 653 to rotate 90 degrees, so that the rice packaging bag is positioned in a vertical state directly below the blanking component 3 and the bag opening component 4. During this process, the rotary motor 651 drives the driving plate 654 to rotate, and the telescopic rod 655 can drive the rotary arm 653 to rotate around the second threaded rod 652 as the axis, so that the clamped rice packaging bag is rotated to a vertical state. The rotary arms 653 on both sides rotate while moving closer to each other along the second threaded rod 652. The rice packaging bag is squeezed from both sides to initially open the bag opening, allowing air to enter the interior of the packaging bag, making it easier for the subsequent bag opening assembly 4 to further open the bag opening. When the pneumatic clamping jaws 66 are worn after long-term use, the rice packaging bag tends to slide down after clamping due to loose clamping. The side of the anti-skid gear 663 in contact with the rice packaging bag is subjected to a downward force, and the anti-skid gear 663 tends to rotate. When the anti-skid gear 663 rotates, it drives the tooth plate 664 to rise through the meshing action with the tooth plate 664, and then the second wedge block 665 acts on the first wedge block 662 to push the first wedge block 662 out a certain distance, so that it clamps the rice packaging bag tightly, thereby achieving a better anti-skid effect and preventing the rice packaging bag from sliding down and tilting due to inadequate clamping.
