[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0022] 1. This utility model, by setting a first cylinder, a second cylinder, an upper heat-sealing plate, and a lower heat-sealing plate, when the first cylinder runs, it will drive the hinge block to move in opposite directions through two movable blocks. At this time, the upper heat-sealing plate and the lower heat-sealing plate will clamp the opening of the packaging bag during the movement. Since the upper heat-sealing plate and the lower heat-sealing plate are equipped with heating wires inside, the upper heat-sealing plate and the lower heat-sealing plate can seal the opening of the packaging bag. When the second cylinder runs, it will drive the movable block to move to the left through the movable plate. At this time, the upper heat-sealing plate and the lower heat-sealing plate will drive the packaging bag to the left, so that the rice ball can enter the inside of the packaging bag, thereby automatically sealing the rice ball. Furthermore, due to the design of the upper heat-sealing plate and the lower heat-sealing plate, when the upper heat-sealing plate and the lower heat-sealing plate clamp the packaging, they will automatically cut the packaging.
[0023] 2. This utility model, by setting a first guide block, a second guide block, heating wires, and heat-sealing wheels, provides excellent guidance for the packaging bag due to the design of the first and second guide blocks, allowing the packaging bag to automatically bend into a circle. The gap at the bottom of the first guide block allows both ends of the packaging bag to extend to the outside of the first guide block and be in a close fit. The bidirectional screw is threadedly connected to the connecting block; when the bidirectional screw rotates, it drives the two connecting blocks to move in opposite directions. At this time, the two heat-sealing wheels clamp the two ends of the packaging bag during this opposite movement. The design of the two heating wires allows the two heat-sealing wheels to seal the sides of the packaging bag when clamping it. Since the two heat-sealing wheels are movably connected to two round shafts, when the packaging bag is pulled to the left, the two heat-sealing wheels will rotate and continue to seal the packaging bag.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] like Figures 1 to 8 As shown, this utility model provides a processing and packaging device for rice balls, comprising:
[0035] A base 1 has vertical plates 2 fixedly installed on both the front and rear sides of the top of the base 1. A long plate 17 is fixedly installed on the top of the vertical plate 2. A fixing frame 3 is fixedly installed on the left side of the top of the base 1. A fixing block 16 is fixedly installed on the outer surface of the fixing frame 3. A long rod 21 is fixedly sleeved inside the vertical plate 2 and the fixing frame 3.
[0036] The motion mechanism is located inside the fixed block 16 and the long plate 17;
[0037] The encapsulation mechanism is located inside the top of the base 1;
[0038] The encapsulation mechanism includes a motion plate 4, the outer surface of which is movably connected to the interior of the top of the base 1. A fixed plate 5 is fixedly installed on the right side of the top of the motion plate 4. A first cylinder 6 is fixedly sleeved inside the fixed plate 5. A movable block 7 is fixedly installed on the left end of the first cylinder 6. A short rod 8 is movably sleeved inside the movable block 7. Support plates 9 are fixedly sleeved on both ends of the short rod 8. The bottom end of the support plate 9 is fixedly connected to the top of the motion plate 4. A motion rod 10 is movably sleeved inside the movable block 7. A hinge block 11 is hinged to the other end of the motion rod 10. There are two sets of hinge blocks 11. An upper heat-sealing plate 12 and a lower heat-sealing plate 13 are fixedly installed on the outer surfaces of the two sets of hinge blocks 11, respectively. A vertical rod 14 is movably sleeved inside the two sets of hinge blocks 11. Motion blocks 15 are fixedly installed on both the upper and lower ends of the vertical rod 14. The interior of the motion block 15 is movably sleeved on the outer surface of the long rod 21.
[0039] When the operator simultaneously activates the two first cylinders 6, the two first cylinders 6 will drive the two movable blocks 7 to move to the left along the two sets of short rods 8. Due to the design of the two short rods 8, the two movable blocks 7 will run more stably. At the same time, the two movable blocks 7 will drive the two sets of hinge blocks 11 to move towards each other along the two vertical rods 14 through the two sets of moving rods 10. At this time, the upper heat sealing plate 12 and the lower heat sealing plate 13 will move towards each other under the drive of the two sets of hinge blocks 11. The upper heat sealing plate 12 and the lower heat sealing plate 13 will clamp the opening of the packaging bag in the process of moving towards each other. Since the upper heat sealing plate 12 and the lower heat sealing plate 13 are equipped with heating wires inside, they can seal the packaging bag at the same time when clamping the opening of the packaging bag. Furthermore, due to the design of the upper heat sealing plate 12 and the lower heat sealing plate 13, the packaging will be automatically cut when the upper heat sealing plate 12 and the lower heat sealing plate 13 clamp the packaging.
[0040] The sports facilities include:
[0041] The second cylinder 18 has its outer surface fixedly connected to the inside of the fixed block 16 and the long plate 17, and a movable plate 19 is fixedly installed on the left end of the second cylinder 18.
[0042] The connecting rod 20 is fixedly connected to the right side of the movable plate 19 at its left end, and the outer surface of the right end of the connecting rod 20 is fixedly connected to the outer surface of the moving block 15.
[0043] Due to the design of the fixed block 16 and the long plate 17, the second cylinder 18 can be well supported. When the second cylinder 18 is running, the movable plate 19 will drive the moving block 15 to move to the left along the long rod 21 through the connecting rod 20. At this time, the moving block 15 will drive the hinge block 11 to move to the left through the vertical rod 14. Since the upper heat sealing plate 12 and the lower heat sealing plate 13 are in the state of clamping the packaging bag, the packaging bag will move to the left under the drive of the upper heat sealing plate 12 and the lower heat sealing plate 13, so that the rice ball can enter the packaging bag, thereby automatically putting the rice ball into the bag.
[0044] The base 1 has a collection box 22 that is movably connected inside, and a handle 23 is fixedly installed on the top left side of the collection box 22.
[0045] Due to the design of the collection box 22, it is possible to collect packaged rice balls. Due to the design of the handle 23, the operator can pull the collection box 22 out of the base 1 by pulling the handle 23.
[0046] Among them, a baffle 24 is fixedly installed on the right side of the top of the base 1, and a driven roller 25 is movably sleeved on the left side inside the baffle 24.
[0047] Because the driven roller 25 is movably sleeved inside the baffle 24, the driven roller 25 can rotate inside the baffle 24.
[0048] Among them, a motor 26 is fixedly installed on the right side of the front of the baffle 24, and a rotating shaft 27 is fixedly sleeved on the other end of the output shaft of the motor 26. The outer surface of the rotating shaft 27 is movably sleeved with the inside of the baffle 24.
[0049] When motor 26 is running, shaft 27 will rotate.
[0050] Among them, a drive roller 28 is fixedly sleeved on the outer surface of the rotating shaft 27, and the drive roller 28 is connected to the driven roller 25 through the transmission belt 29.
[0051] When the rotating shaft 27 rotates, it will drive the drive roller 28 to rotate. At this time, the drive roller 28 will drive the driven roller 25 to rotate through the transmission belt 29. The transmission belt 29 will then be able to drive the rice ball to move to the left and enter the inside of the packaging bag.
[0052] Among them, an arc-shaped bracket 30 is fixedly installed at the top of the base 1, a first guide block 31 is fixedly sleeved inside the arc-shaped bracket 30, and a second guide block 32 is provided inside the first guide block 31.
[0053] Due to the design of the first guide block 31 and the second guide block 32, the packaging bag can be guided and automatically bent into a circle. Due to the design of the bottom gap of the first guide block 31, both ends of the packaging bag can extend to the outside of the first guide block 31 through the gap, and at this time the two ends of the packaging bag will be in a close fit.
[0054] The arc-shaped bracket 30 has a bidirectional screw 34 movably sleeved inside, and a screwing block 33 is fixedly installed at the front end of the bidirectional screw 34. The back of the screwing block 33 is movably connected to the outer surface of the arc-shaped bracket 30.
[0055] When the operator turns the turning block 33, the bidirectional screw 34 will rotate under the drive of the turning block 33.
[0056] The outer surface of the bidirectional screw 34 is threaded with a connecting block 35, and the bottom end of the connecting block 35 is movably connected to the top end of the base 1.
[0057] Since the bidirectional screw 34 is threadedly connected to the connecting block 35, when the bidirectional screw 34 rotates, it will drive the two connecting blocks 35 to move towards each other along the top of the base 1.
[0058] The connecting block 35 has a fixed sleeve of a round shaft 36 inside, a heating wire 37 inside the round shaft 36, and a heat sealing wheel 38 movably sleeved on the outer surface of the round shaft 36.
[0059] When the two connecting blocks 35 move toward each other, the two connecting blocks 35 will drive the two heat sealing wheels 38 to move toward each other through the two round shafts 36. At this time, the two heat sealing wheels 38 will clamp the two ends of the packaging bag in the process of moving toward each other. Due to the design of the two heating wires 37, the two heat sealing wheels 38 can seal the sides of the packaging bag when clamping the packaging bag.
[0060] Working principle and usage process of this utility model:
[0061] First, the operator places the packaging bag between the first guide block 31 and the second guide block 32. Due to the design of the first guide block 31 and the second guide block 32, the packaging bag will be well guided. Under the guidance of the first guide block 31 and the second guide block 32, the packaging bag will become round. At the same time, both ends of the packaging bag will extend through the gap at the bottom of the first guide block 31 to below the bottom of the first guide block 31. At this time, the two ends of the packaging bag will be in a closed state. Then, the operator turns the turning block 33. At this time, the bidirectional screw 34 will be driven by the turning block 33. The screw rotates downwards. Since the outer surface of the bidirectional screw 34 is threaded into the inner thread of the connecting block 35, when the bidirectional screw 34 rotates, it will drive the two connecting blocks 35 to move towards each other along the top of the base 1. At the same time, the two connecting blocks 35 will drive the two heat sealing wheels 38 to move towards each other through the two round shafts 36. Then, the two heat sealing wheels 38 will clamp the two ends of the packaging bag in the opposite direction. Due to the design of the two heating wires 37, the heat sealing wheels 38 can be heated. Therefore, when the two heat sealing wheels 38 clamp the packaging bag, the sides of the packaging bag will be sealed at the same time.
[0062] The operator then simultaneously activates two first cylinders 6. These cylinders drive two movable blocks 7 to move to the left along the outer surface of the two sets of short rods 8. Simultaneously, the movable blocks 7 drive two sets of moving rods 10. The other ends of the moving rods 10 then drive two sets of hinge blocks 11 to move towards each other along the outer surface of the two sets of vertical rods 14. At the same time, the hinge blocks 11 drive the upper heat-sealing plate 12 and the lower heat-sealing plate 13 to move towards each other. The upper heat-sealing plate 12 and the lower heat-sealing plate 13 will then clamp the opening of the packaging bag during their relative movement. Since both the upper heat-sealing plate 12 and the lower heat-sealing plate 13 are equipped with heating wires, when the upper heat-sealing plate... When the upper heat sealing plate 12 and the lower heat sealing plate 13 clamp the packaging bag, they will seal the opening on one side of the packaging bag. Then, the operator starts the second cylinder 18. At this time, the movable plate 19 will drive the moving block 15 to move to the left along the outer surface of the long rod 21 through the connecting rod 20. Since the upper heat sealing plate 12 and the lower heat sealing plate 13 are clamping the packaging bag at this time, the packaging bag will move to the left under the drive of the upper heat sealing plate 12 and the lower heat sealing plate 13. At this time, the packaging bag will drive the two heat sealing wheels 38 to rotate around the connection point with the round shaft 36 as the axis. During this process, the heat sealing wheels 38 will continuously seal the side of the packaging bag while rotating.
[0063] Next, the operator starts motor 26. At this time, shaft 27 drives drive roller 28 to rotate. Simultaneously, drive roller 28 drives driven roller 25 to rotate via transmission belt 29. Transmission belt 29 then transports the rice ball to the left. When transmission belt 29 moves the rice ball into the packaging bag, the operator starts the two first cylinders 6 again. The upper heat-sealing plate 12 and lower heat-sealing plate 13 release their clamping action on the packaging. Then, the operator starts the second cylinder 18. The movable plate 19, via connecting rod 20, drives moving block 15 to the right to reset. When the outer surface of the upper heat sealing plate 12 is in contact with the outer surface of the vertical plate 2, the operator starts the two first cylinders 6 again. At this time, the upper heat sealing plate 12 and the lower heat sealing plate 13 will move towards each other again to seal the opening at the other end of the packaging bag. Due to the design of the outer surfaces of the upper heat sealing plate 12 and the lower heat sealing plate 13, they will mesh with each other when the upper heat sealing plate 12 and the lower heat sealing plate 13 clamp the packaging. At this time, the upper heat sealing plate 12 and the lower heat sealing plate 13 will be able to automatically cut the packaging, thereby realizing the function of automatically bagging and sealing the rice ball. Then the packaged rice ball will fall into the inside of the collection box 22 to complete the collection.
