Description

Technical Field

[0001] This application relates to the field of rice packaging technology, and in particular to a quantitative weighing device for rice packaging. Background Technology

[0002] On existing rice packaging production lines, the rice packaging process typically involves multiple steps, including weighing the rice, opening the packaging bag, filling the rice, and sealing the packaging bag.

[0003] In practice, some steps still rely on manual operation. Specifically, during rice packaging, workers need to manually place the rice bags onto the conveyor and manually pull the bag opening as the rice is being added to ensure it flows smoothly into the bag. However, this manual method is prone to errors due to improper handling or soft bags, causing one side of the bag opening to collapse and resulting in spillage during the filling process. This not only affects the packaging efficiency but may also lead to inconsistent packaging quality and increase the workload of subsequent processing.

[0004] To address the aforementioned issues, a quantitative weighing device for rice packaging has been designed. Utility Model Content

[0005] This application provides a quantitative weighing device for rice packaging to solve the problem in related technologies where workers need to manually pull the bag opening to open the packaging bag during the rice packaging process. This can easily lead to the bag opening collapsing on one side due to improper operation or the bag being too soft, causing rice to spill during the dispensing process.

[0007] The machine body is provided with a feeding unit for positioning and feeding rice, and the feeding unit includes a feeding port for discharging rice.

[0008] A conveyor located on one side of the machine body is used to place and transport rice packaging bags;

[0009] The bag-opening mechanism, located on the machine body and positioned below the feed inlet, is used to open the rice packaging bags.

[0010] The bag-supporting mechanism includes two slide rails arranged opposite to each other on the machine body. A slide block is provided on the slide rail. Two tension rods are rotatably provided at one end of the slide block. A driving component is provided inside the slide block. The driving component is used to drive the corresponding two tension rods to move closer to each other or unfold, thus opening the bag opening of the rice packaging bag. A lifting part is also provided on the slide block. The lifting part is used to drive the slide block to move up and down.

[0011] In some embodiments, the feeding unit includes a feeding bin with a cavity for holding rice. A support plate is rotatably mounted inside the feeding bin, and a weighing scale is mounted on the support plate. A solenoid valve is mounted above the feeding bin, and a rotating component is mounted on the feeding bin to drive the support plate and the weighing scale to rotate.

[0012] In some embodiments, the rotating component includes a drive motor mounted on the feed hopper, the output shaft of the drive motor being provided with a rotating shaft, and the other end of the rotating shaft being connected to the support plate.

[0013] In some embodiments, mounting grooves are provided at opposite ends of the two slides, and the two sides of the mounting grooves and the end of the slide near the other side are open.

[0014] The driving component includes a rotating shaft that is rotatably mounted on the mounting groove, a gear on the rotating shaft, two adjacent gears meshing with each other, and a second drive motor on the slide, the output shaft of the second drive motor being connected to one end of any rotating shaft.

[0015] One end of the tensioning rod is mounted on the rotating shaft.

[0016] In some embodiments, the tensioning rod includes a transmission rod and a support rod connected to each other, the other end of the transmission rod being connected to the outer side of the corresponding rotating shaft and located above the gear, and the transmission rod and the support rod being arranged perpendicularly.

[0017] In some embodiments, the lifting unit includes two electric push rods disposed opposite each other on the top of the machine body, the piston rod of the electric push rod being provided with a connecting rod at the bottom end, and the other end of the connecting rod being connected to the slide block.

[0018] In some embodiments, a dust removal mechanism is also included, which includes a dust removal chamber disposed outside the feeding hopper, two ventilation nets being embedded opposite each other on the feeding hopper, and an exhaust pipe being disposed on the dust removal chamber, the other end of which is connected to an external dust collection system.

[0019] In some embodiments, the conveyor has an L-shaped enclosure on the side near the machine body, which is used to support one side of the rice packaging bag.

[0020] In some embodiments, a sewing machine is also included, which is arranged along the length of the conveyor and parallel to the machine body.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] This application provides a quantitative weighing device for rice packaging, which can solve the problem in related technologies where workers need to manually pull the bag opening to open the packaging bag during the rice packaging process. This can easily lead to the bag opening collapsing on one side due to improper operation or the bag being too soft, causing rice to spill during the dispensing process.

[0033] Please see Figures 1-3 A rice packaging quantitative weighing device includes: a body 1, on which a feeding unit 2 for positioning and feeding rice is provided, the feeding unit 2 including a feeding port 26 for discharging rice; a conveyor 3 arranged on one side of the body 1 for placing and conveying rice packaging bags; and a bag-supporting mechanism 4 arranged on the body 1, which is arranged below the feeding port 26 and is used to support the rice packaging bags. The bag-supporting mechanism 4 includes two slide rails 41 arranged opposite to each other on the body 1, and a slide seat 42 is provided on the slide rails 41. Two tension rods 43 are rotatably arranged at one end of the slide seat 42. A driving member 44 is provided inside the slide seat 42. The driving member 44 is used to drive the corresponding two tension rods 43 to move closer to each other or unfold, thereby opening the mouth of the rice packaging bag. A lifting part 45 is also provided on the slide seat 42, and the lifting part 45 is used to drive the slide seat 42 to rise and fall.

[0034] The rice is placed in the feeding unit 2, and the feeding port 26 is the exit for the rice to enter the packaging bag.

[0035] The rice packaging bag is placed on the conveyor 3. The operation opens the packaging bag, and the bag-supporting mechanism 4 starts to work. The lifting part 45 adjusts the position of the slide 42 according to the height of the rice packaging bag to ensure that the tensioning rod 43 can accurately extend into the bag opening.

[0036] Subsequently, the drive unit 44 is activated, driving the two tension rods 43 to unfold relative to each other. Since the tension rods 43 are rotatably mounted on the slide block 42, when they unfold relative to each other, the four tension rods 43 can open the bag opening into a quadrilateral shape, thereby opening the bag opening of the rice packaging bag.

[0037] Once the rice bag is opened, the feeding unit 2 begins to quantitatively add rice into the bag through the feeding port 26. After filling, the bag-opening mechanism 4 returns to its original position, releasing the rice bag, which then continues to be conveyed along the conveyor 3 to the next process, such as the sealing machine, for sealing. During this process, the operator holds the bag opening to prevent it from tipping over.

[0038] The automated bag-opening mechanism 4 enables the rice packaging bags to be opened quickly and accurately, evenly and stably, preventing rice spillage caused by one side of the bag collapsing. This helps maintain the cleanliness and hygiene of the rice inside the packaging bag, improving packaging quality. Furthermore, workers no longer need to perform tedious manual bag-opening operations, significantly reducing labor intensity. High adaptability:

[0039] The bag-supporting mechanism 4 of this device can adapt to rice packaging bags of different sizes and materials by adjusting the unfolding angle of the tension rod 43 and the lifting height of the slide 42. This makes the device more widely applicable and flexible.

[0040] like Figure 3 As shown, the feeding unit 2 in this embodiment includes a feeding bin 21, which has a cavity for holding rice. A support plate 22 is rotatably mounted inside the feeding bin 21. A weighing scale 23 is mounted on the support plate 22. A solenoid valve 24 is mounted above the feeding bin 21. A rotating component 25 is mounted on the feeding bin 21, which drives the support plate 22 and the weighing scale 23 to rotate.

[0041] The rice is fed into the cavity inside the feeding hopper 21 via a solenoid valve 24. When the rice falls onto the weighing scale 23 on the support plate 22, the weighing scale 23 starts working and accurately measures the weight of the rice on the support plate 22.

[0042] The weighing scale 23 continuously monitors the weight of the rice and compares it with a preset weight value. When the measured weight of the rice reaches the preset value, the solenoid valve 24 automatically closes, stopping the feeding of rice into the feeding hopper 21. Simultaneously, the rotating component 25 starts, driving the support plate 22 and the weighing scale 23 to rotate together. This action ensures that the rice flows evenly downwards from the weighing scale 23 and flows out through the feeding port 26. The design of the rotating component 25 ensures the uniformity and stability of the feeding process.

[0043] As the rice flows out of the feed inlet 26, the bag-opening mechanism 4 below has already opened the rice packaging bag. The rice smoothly enters the packaging bag until the set weight is reached. At this point, the bag-opening mechanism 4 releases the bag opening.

[0044] The precise measurement by the weighing scale 23 and the precise control by the solenoid valve 24 ensure that the amount of rice dispensed each time meets the standard requirements, greatly improving the precision and accuracy of packaging.

[0045] Specifically, in this embodiment, the rotating component 25 includes a drive motor mounted on the feeding bin 21, the output shaft of the drive motor being provided with a rotating shaft, and the other end of the rotating shaft being connected to the support plate 22.

[0046] The rotating component 25 mainly consists of a drive motor, a rotating shaft, and a connecting mechanism. The drive motor is mounted on the feeding hopper 21, and its output shaft is connected to the rotating shaft. The other end of the rotating shaft is fixedly connected to the support plate 22 through the connecting mechanism.

[0047] When the measured weight of the rice reaches the preset value, the solenoid valve 24 closes, stopping the feeding of rice into the feeding hopper 21. At this time, the drive motor starts, and its output shaft drives the rotating shaft to rotate. Since the rotating shaft is fixedly connected to the support plate 22 through a connecting mechanism, the support plate 22 and the weighing scale 23 will also rotate together.

[0048] During the rotation, the rice flows evenly downward from the weighing scale 23, flows out through the feed port 26, and enters the packaging bag opened by the bag-supporting mechanism 4 below.

[0049] like Figure 5 and Figure 6In one embodiment, a slider is provided on the slide rail 41, and the other end of the slider is connected to the slide block 42. Each of the two slide blocks 42 has a mounting groove 421 at one opposite end, and both sides of the mounting groove 421 and the end of the slide block 42 near the other side are open. The driving component 44 includes a rotating shaft 441 rotatably mounted on the mounting groove 421, a gear 442 mounted on the rotating shaft 441, two adjacent gears 442 meshing with each other, a second drive motor 443 mounted on the slide block 42, and the output shaft of the second drive motor 443 connected to one end of any rotating shaft 441. One end of the tensioning rod 43 is mounted on the rotating shaft 441. A cavity is formed inside the slide block 42, the bottom end of the rotating shaft 441 extends into the cavity, and the gear 442 is arranged inside the cavity.

[0050] A slider is provided on the slide rail 41, and the other end of the slider is connected to the slide block 42, so that the slide block 42 can slide on the slide rail 41. Each of the two slide blocks 42 has a mounting groove 421 at one end opposite to the other. The two sides of the mounting groove 421 and the end of the slide block 42 near the other side are open, providing sufficient space for the installation of the drive component 44.

[0051] The driving component 44 includes a rotating shaft 441 rotatably mounted on a mounting groove 421, and a gear 442 mounted on the rotating shaft 441. Two adjacent gears 442 mesh with each other to form a gear transmission mechanism, ensuring smooth power transmission. A drive motor 443 is mounted on the slide 42, and its output shaft is connected to one end of either rotating shaft 441, serving as the power source for the gear transmission mechanism.

[0052] One end of the tension rod 43 is mounted on the rotating shaft 441, and the other end is used to adjust the tension of the packaging bag. When the rotating shaft 441 rotates, the tension rod 43 will rotate accordingly, thereby adjusting the angle between the two tension rods 43. The slide 42 has a cavity inside, the bottom end of the rotating shaft 441 extends into the cavity, and the gear 442 is arranged inside the cavity.

[0053] When it is necessary to adjust the opening size and tension of the packaging bag, drive motor 443 starts, and its output shaft drives the connected rotating shaft 441 to rotate. Since two adjacent gears 442 mesh with each other, the rotation of one rotating shaft 441 will drive the rotation of the adjacent rotating shaft 441, forming a gear transmission chain. The rotation of the rotating shaft 441 drives the tension rod 43 to rotate. Since one end of the tension rod 43 is set on the rotating shaft 441, the rotation of the rotating shaft 441 will change the angle between the two tension rods 43. This change in angle will directly affect the opening size and tension of the packaging bag, thereby achieving precise adjustment.

[0054] The opening size and tension of the packaging bag can be precisely adjusted through the gear transmission mechanism and tension rod 43 to ensure packaging quality.

[0055] The structural design allows the opening size and tension of the packaging bag to be flexibly adjusted according to actual needs, adapting to different sizes and types of packaging bags.

[0056] like Figure 5 and Figure 6 As shown, specifically, the tensioning rod 43 includes a transmission rod 431 and a support rod 432 connected to each other. The other end of the transmission rod 431 is connected to the outer side of the corresponding rotating shaft 441 and is located above the gear 442. The transmission rod 431 and the support rod 432 are arranged perpendicularly.

[0057] The other end of the transmission rod 431 is connected to the outside of the corresponding rotating shaft 441 and is located above the gear 442, ensuring that the transmission rod 431 will not interfere with the gear 442.

[0058] The transmission rod 431 and the support rod 432 are arranged perpendicularly, so that the support rod 432 can vertically adjust the opening size and tension of the packaging bag.

[0059] When it is necessary to adjust the opening size and tension of the packaging bag, drive motor 443 starts. Its output shaft drives the connected rotating shaft 441 to rotate. The rotation of the rotating shaft 441 is transmitted to the support rod 432 through the transmission rod 431. Since the transmission rod 431 and the support rod 432 are set perpendicularly, the rotation of the rotating shaft 441 will change the position or angle of the support rod 432. The change in the position or angle of the support rod 432 will directly affect the opening size and tension of the packaging bag, thereby achieving precise adjustment.

[0060] like Figure 2 and Figure 3 As shown, in one embodiment, the lifting part 45 includes two electric push rods 451 disposed opposite to each other on the top of the body 1. The piston rod of the electric push rod 451 is provided with a connecting rod 452 at the bottom end, and the other end of the connecting rod 452 is connected to the slide 42.

[0061] The sliding block 42 and the drive unit 44 and tension rod 43 mounted on the sliding block 42 can be raised and lowered by the extension and retraction of the electric push rod 451.

[0062] When it is necessary to adjust the height of the slide block 42 and the components mounted on it, the electric push rod 451 is activated, the piston rod of the electric push rod 451 extends and retracts, and drives the slide block 42 to rise and fall through the connecting rod 452.

[0063] like Figure 3 As shown, in one embodiment, a dust removal mechanism 5 is also included. The dust removal mechanism 5 includes a dust removal chamber 51 arranged outside the feeding hopper 21. Two ventilation nets 52 are embedded in the feeding hopper 21. An exhaust pipe 53 is provided on the dust removal chamber 51. The other end of the exhaust pipe 53 is connected to an external dust collection system.

[0064] There are two ventilation nets 52 that allow air to pass through but block materials. The dust removal chamber 51 is equipped with an exhaust pipe 53, the other end of which is connected to an external dust collection system to extract air from the dust removal chamber.

[0065] When the feeding hopper 21 is working, the external dust collection system is activated, and air is drawn from the dust collection chamber 51 through the air extraction pipe 53. Since the feeding hopper 21 is equipped with a ventilation net 52, the air will carry the dust in the feeding hopper 21 into the dust collection chamber 51 during the flow process, and then be discharged into the external dust collection system through the air extraction pipe 53, thereby achieving the dust removal effect.

[0066] like Figure 1 As shown, it should be noted that in this embodiment, the conveyor 3 is provided with a side panel 6 on the side close to the machine body 1. The side panel 6 is L-shaped and is used to support one side of the rice packaging bag.

[0067] During the conveyor 3's transport of rice packaging bags, the L-shaped side panel 6 supports one side of the packaging bag to ensure stable transport and prevent tipping or deformation.

[0068] This embodiment also includes a sewing machine 7, which is arranged along the length of the conveyor 3 and is parallel to the machine body 1.

[0069] Sewing machine 7 is used to sew rice packaging bags that have been conveyed by conveyor 3 to complete the packaging process.
