[0002] In the production process of noodles, after the noodles are made, they need to be weighed according to the specified weight, and then the weighed noodles are packaged to complete the production of noodles. In the process of weighing the noodles, a combination weigher is often used for weighing.

[0003] A combination weigher generally consists of multiple weighing units with independent feeding structure, weighing structure and discharging structure. The weight in each weighing unit is automatically optimized and combined by using the principle of permutation and combination to calculate the best combination closest to the quantitative value for packaging.

[0004] When noodles enter the weighing structure of the current combination weigher for weighing, they usually fall from the feed hopper into the buffer hopper, which is used to temporarily store the noodles. The material door of the buffer hopper is opened to allow the noodles to fall into the weighing structure, and the weight of the noodles is controlled by controlling the opening time of the buffer hopper. However, only using the buffer hopper to control the weight of the noodles falling into the weighing structure cannot meet the use requirements when the precision of the combination weigher is high. Summary of the invention

[0005] In order to achieve the pre-distribution of the weight of noodles entering the weighing structure and improve the accuracy of the combination weigher, the present application provides a combination weigher for quantitative weighing of noodles.

The retractable belt reaches the top of multiple receiving hoppers through telescopic movement, so that the noodles can enter the receiving hopper, and the noodles are scattered, sorted and pre-distributed by the scattering and distribution assembly, so that some of the noodles can enter the weighing device, and the weighing device weighs the noodles. The weighed noodles are combined and output by the combining device, and then the noodles output by the combining device are sent to the next process.

[0008] By setting a breaking and distributing component in the receiving hopper, the noodles can be distributed in advance in the receiving hopper, which is beneficial to reduce the weight of the noodles entering the weighing device at one time, making it easier to control the weight of the noodles and improve the accuracy of the combination weigher.

[0009] Optionally, the breaking and distributing assembly includes a discharge plate, a valve plate, a pushing cylinder, a baffle plate and a thumb wheel; the discharge plate is rotatably connected to the receiving hopper; the receiving hopper is provided with a vibration assembly for driving the discharge plate to vibrate; a first comb tooth is provided at the end of the discharge plate; the valve plate is provided with a second comb tooth; the first comb tooth and the second comb tooth cooperate with each other; the baffle plate is connected to the receiving hopper; the pushing cylinder is connected to the receiving hopper and is used to drive the valve plate to move toward or away from the baffle plate; the thumb wheel is rotatably connected to the receiving hopper and driven by a driving motor; the thumb wheel is provided with a plurality of discharge troughs; the noodles pass through the discharge plate and the valve plate and reach the discharge troughs.

When the discharge plate 22 vibrates, the distance between the discharge plate 22 and the lower end of the partition 71 can change, thereby allowing some noodles to pass through, and realizing the scattered distribution of the noodles. A spring piece 7 is also provided above the discharge plate 22. When the noodles fall along the slope of the discharge plate 22, the noodles hit the spring piece 7, causing the spring piece 7 to tilt. The spring piece 7 plays a role similar to a door curtain, which can slow down the falling speed of the noodles, thereby facilitating the breaking up and distribution of the noodles.

[0036] The end of the discharge plate 22 is provided with a first comb tooth 74, the inner side of the receiving hopper 21 is fixedly connected with a bracket, a push cylinder 73 is placed on the bracket, the output end of the push cylinder 73 is connected with a valve plate 72, the valve plate 72 is tilted, the valve plate 72 is provided with a second comb tooth 75, the first comb tooth 74 and the second comb tooth 75 cooperate with each other, so that when the discharge plate 22 vibrates, the valve plate 72 and the discharge plate 22 will not interfere with each other. At the same time, the noodles on the discharge plate 22 can be intercepted by the valve plate 72, and when the push cylinder 73 pushes the valve plate 72 to move, the noodles on the discharge plate 22 can reach above the valve plate 72. The output end of the push cylinder 73 is also connected with an auxiliary plate, the auxiliary plate is arranged below the valve plate 72, and the first comb tooth 74 can abut against the auxiliary plate, so that the vibration degree of the discharge plate 22 can be limited by the auxiliary plate.

[0037] The receiving hopper 21 is also fixed with a baffle plate 24. The receiving hopper 21 is provided with a dial wheel 23 and a driving motor for driving the dial wheel 23 to rotate. The dial wheel 23 is located above the temporary storage hopper 31. The dial wheel 23 is evenly provided with three material discharge grooves 25, and the side wall of the dial wheel 23 is provided with a scraping groove 26.

As the pushing cylinder 73 moves, the noodles reach the valve plate 72, and the valve plate 72 retracts after abutting against the baffle plate 24. Under the action of gravity, the material can enter the material discharge groove 25 along the baffle plate 24 to achieve noodle distribution. When the dial wheel 23 rotates, the scraping teeth 27 slide in the scraping groove 26, and can scrape off some noodles that have not entered the discharge groove 25, so as to keep the dial wheel 23 clean. As the dial wheel 23 rotates, the noodles in the discharge groove 25 reach the temporary storage bucket 31. The dial wheel 23 is also coaxially connected to a detection disk, and the detection disk is electrically connected to a counter, and the counter is set to count the number of rotations of the dial wheel 23.

[0038] The temporary storage bucket 31 and the weighing bucket 32 ​​are arranged vertically, and the feed port of the weighing bucket 32 ​​is arranged below the discharge port of the temporary storage bucket 31. The weighing bucket 32 ​​is connected to a weighing component, and the weight of the noodles in the weighing bucket 32 ​​is detected by the weighing component. The discharge ports of the temporary storage bucket 31 and the weighing bucket 32 ​​are both provided with closing components, and the noodles in the temporary storage bucket 31 / the weighing bucket 32 ​​are prevented from falling. When the discharge port at the bottom of the temporary storage bucket 31 is in a closed state, the noodles are temporarily stored in the temporary storage bucket 31. When the discharge port of the temporary storage bucket 31 is opened, the noodles fall from the discharge port of the temporary storage bucket 31 into the weighing bucket 32. A weighing sensor is arranged on one side of the weighing bucket 32, and the weighing sensor weighs the noodles in the volume of the weighing bucket 32. When the noodles in the weighing bucket 32 ​​reach a set weight, the discharge port of the temporary storage bucket 31 is closed, so that the noodles in the temporary storage bucket 31 do not continue to fall into the weighing bucket 32. The closing assembly and the weighing sensor both adopt structures of current technology to achieve the corresponding purposes.

[0039] In this embodiment, the combination device 4 includes a conveyor 41 and a combination bucket 42. The conveyor 41 is used to convey noodles, and the combination bucket 42 is used to collect multiple noodles. Specifically, the noodles of two adjacent weighing buckets 32 are first collected by the first combination bucket 42, and the noodles collected by the first combination buckets 42 of the four corresponding rows of units fall into the first conveyor 41. The first conveyor 41 conveys the noodles into the second combination bucket 42, and the second combination bucket 42 collects the noodles and then falls into the second conveyor 41. The second conveyor 41 is divided into two sections for conveying in opposite directions, so that the two rows of noodles are conveyed into the third combination bucket 42 in the middle, and the noodles are finally collected, and then the collected noodles are sent out through the third conveyor 41.

[0040] Among them, the first transmission member 41, the second transmission member and the third transmission member 41 are all configured as conveyor belts. The first combination bucket 42, the second combination bucket 42 and the third combination bucket 42 have the same structural configuration, and all include a beam frame, a support plate, and a bucket box, and the bucket box is connected to the beam frame through the support plate. Side panels are provided at the front and rear ends of the lower ends of the bucket boxes, and the lower ends of the bucket boxes are connected to bucket doors through hinges for rotation to the left and right. The beam frame is hinged with a driving cylinder, and the bucket door is hinged to the output end of the driving cylinder, so that the left and right bucket doors can be driven to rotate by the driving cylinder. When the bucket door and the side panel are in contact, the bucket door is closed at this time, and the noodles in the bucket box cannot fall. When the bucket door is opened, the noodles in the bucket box can fall onto the conveyor belt for transmission.

[0041] When weighing and packaging noodles, there are a total of sixteen weighing buckets 32 in this embodiment, and the weight of noodles set in each weighing bucket 32 ​​is the same. The weight of noodles required for final packaging can be the sum of the weights of noodles output by the eight weighing buckets 32. However, the errors generated by different weighing buckets 32 are different. In order to reduce the error of the weight of noodles required for final packaging, after the weighing sensor of a weighing bucket 32 ​​weighs the weight of noodles in the weighing bucket 32, the noodles are combined according to the weights of noodles in other weighing buckets 32, and the noodles in the weighing bucket 32 ​​closest to the weight required for final packaging after combination are released. The corresponding weighing bucket 32 ​​is driven by the driving cylinder to open the bucket door to release the noodles, and finally merge into the third combination bucket 42 and output from the output end of the third transmission member, and then packaged, thereby improving the weighing accuracy and weighing efficiency of noodles.

[0042] The implementation principle of a combination weigher for quantitative weighing of noodles in an embodiment of the present application is as follows: noodles fall into the lower hopper 11 from the previous process, and reach the retractable belt through the lower hopper 11. The rotating motor 54 drives the screw rod 53 to rotate, driving the moving rod 55 to move along the slide groove 56, thereby realizing the movement of the moving frame 52, driving the slider 5 and the moving roller 18 to move along the slide groove 51, and the driven roller 15 moves to drive the end of the conveying belt 13 away from the conveying frame 12 to approach or move away from the conveying frame 12, thereby realizing the extension and retraction of the conveying belt 13. When the output end of the retractable belt reaches above the receiving hopper 21, the noodles enter the receiving hopper 21.

[0043] After the noodles enter the receiving hopper 21, they fall along the discharge plate 22. The vibration component drives the discharge plate 22 to vibrate so as to arrange and adjust the noodles, improve the neatness of the noodles, and slow down the falling speed of the noodles through the spring piece 7. The spacing between the discharge plate 22 and the partition 71 allows some noodles to pass through, thereby realizing the primary distribution; the noodles fall to the end of the discharge plate 22 and are intercepted by the valve plate 72. The valve plate 72 moves toward the material blocking plate 24, retracts after touching it, and some noodles fall into the discharge trough 25 of the dial wheel 23 under the action of gravity, thereby realizing the secondary distribution. The noodles in the discharge trough 25 reach the temporary storage bucket 31 as the dial wheel 23 rotates, and then reach the weighing bucket 32.

[0044] The closing component prevents the noodles in the weighing bucket 32 ​​from falling, and the noodles in the volume of the weighing bucket 32 ​​are weighed by the weighing component. When the set weight is reached, the discharge port of the temporary storage bucket 31 is closed, so that the noodles in the temporary storage bucket 31 do not continue to fall into the weighing bucket 32. The best combination that is closest to the quantitative value is calculated through the principle of permutation and combination, and the corresponding discharge port of the weighing bucket 32 ​​is opened. The noodles in the weighing bucket 32 ​​fall into the combining bucket 42 for combination, and are transported to the next packaging process through the conveyor 41.

[0045] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
