Description

Technical Field

[0001] This utility model belongs to the field of automatic feeding and weighing technology for soft strip-shaped items, specifically relating to an automatic weighing device for fresh noodle soft strip-shaped items. Background Technology

[0002] Currently, the weight control of fresh noodles mainly employs two methods: one is to control the weight by adjusting the length of the noodles or soft materials. This method relies on repeated adjustments to the automatic noodle cutter, and multiple readjustments are required for different noodle varieties, making the operation cumbersome and inefficient. Furthermore, the difficulty in heat dissipation of fresh noodles easily affects their quality. The other method is manual weighing, but each weighing must be at least 500 grams, limiting accuracy and efficiency, and incurring high labor costs. Both methods have significant limitations and cannot meet the requirements for efficient and precise weight control. Therefore, a highly automated and adaptable fresh noodle weight control technology is urgently needed to solve these problems. Utility Model Content

[0003] The present invention aims to provide an automatic weighing device for soft strips of fresh noodles, solving the technical problems of cumbersome operation and low efficiency of existing methods for controlling the weight of fresh noodles.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] The automatic weighing equipment for fresh noodles includes a frame, a hopper and a receiving platform installed on the left side of the frame, and a receiving and conveying mechanism, an inclined uniform feeding mechanism, an inductive quantitative weighing mechanism and an automatic pushing mechanism.

[0006] The material receiving and conveying mechanism includes a first variable speed motor, a main double-row sprocket, and an auxiliary double-row sprocket. The first variable speed motor is mounted on the frame, and the main double-row sprocket and the auxiliary double-row sprocket are rotatably mounted on the frame. The main double-row sprocket is connected to the auxiliary double-row sprocket through two chains with a distance between them. The first variable speed motor is driven by the main double-row sprocket.

[0007] The inclined uniform feeding mechanism includes a second variable speed motor, a drive sprocket, and a driven sprocket. The drive sprocket is mounted on the frame, and the driven sprocket is mounted inside the hopper. The driven sprocket is higher than the drive sprocket. The drive sprocket is connected to the driven sprocket via a conveyor chain located between the two chains. The conveyor chain has several teeth arranged side-by-side at equal intervals. The second variable speed motor is driven by the drive sprocket.

[0008] The receiving platform is located directly below the driven sprocket. The inductive quantitative weighing mechanism is used to sense and calculate the weight of the fresh noodles passing through the driven sprocket. The automatic pushing mechanism is used to push the fresh noodles that fall on the receiving platform. The inductive quantitative weighing mechanism is connected to the first variable speed motor, the second variable speed motor and the automatic pushing mechanism respectively.

[0009] Furthermore, the inductive quantitative weighing mechanism is a linear scale, which is placed on the receiving platform.

[0010] Furthermore, the inductive quantitative weighing mechanism consists of a photoelectric counter and a relay. The photoelectric counter is installed on the inner wall of the hopper and faces the driven sprocket. The relay is connected to the photoelectric counter, the first variable speed motor, the second variable speed motor, and the automatic pushing mechanism.

[0011] Furthermore, the automatic feeding mechanism includes a feeding plate, a pulley, a transfer plate, and an electromagnetic push-pull rod. The upper end of the feeding plate is hinged to the bottom of the hopper. The electromagnetic push-pull rod and the pulley are mounted on the hopper. One end of the transfer plate is rotatably mounted on the hopper. The other end of the transfer plate is connected to the middle side of the feeding plate by a first steel wire, which is wound around the pulley. The end of the electromagnetic push-pull rod is connected to the transfer plate by a second steel wire. A spring seat is mounted on the frame. A pull rod is connected to the middle side of the feeding plate, and the pull rod is connected to the spring seat by a spring.

[0012] Furthermore, the first variable speed motor drives the main double-row sprocket to rotate through the first chain drive structure, and the second variable speed motor drives the drive sprocket to rotate through the second chain drive structure.

[0013] Furthermore, two baffles are also provided on the frame. The baffles have an L-shaped cross-section and are arranged side by side. The lower half of the two chains is located between the two baffles.

[0014] Compared with existing technologies, the advantages of this invention are as follows: The equipment adopts a compact design, small in size but significantly improving weighing efficiency. Through a unique method of sequentially weighing single noodles, it mimics the precision of manual weighing, minimizing errors while achieving high-speed continuous operation. Compared to traditional methods, this equipment eliminates the need for repeated adjustments for different noodle varieties, offering strong versatility and significantly reducing operational complexity. The innovative structural design ensures sufficient heat dissipation of fresh noodles during transport, effectively solving the problem of poor heat dissipation in traditional methods. The equipment can seamlessly connect with fully automatic noodle cutters, conveyor belts, and packaging machines to form a complete automated production line, achieving intelligent operation throughout the entire process from noodle cutting and weighing to packaging, significantly improving production efficiency. This weighing system not only boasts high measurement accuracy and stability but also fully adapts to the needs of continuous industrial production, resulting in a qualitative leap in the automation level and output of fresh noodle production, providing food processing enterprises with an efficient and reliable automation solution.

[0021] 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.

[0022] The present invention will be further described in detail below with reference to the embodiments.

[0023] like Figure 1-4 As shown, here is a specific embodiment 1 of the automatic weighing device for fresh noodle strips provided by this utility model:

[0024] An automatic weighing device for soft strips of fresh noodles includes a frame 1. A hopper 2 and a receiving platform 3 are installed on the left side of the frame 1. The frame 1 is also equipped with a receiving and conveying mechanism, an inclined uniform feeding mechanism, an inductive quantitative weighing mechanism, and an automatic pushing mechanism.

[0025] The receiving and conveying mechanism is used to receive the noodles output by the automatic noodle cutter and drive them to the left. It includes a first speed-changing motor 8, a main double-row sprocket 9 and an auxiliary double-row sprocket 10. The first speed-changing motor 8 is mounted on the frame 1. The main double-row sprocket 9 and the auxiliary double-row sprocket 10 are rotatably mounted on the frame 1. The main double-row sprocket 9 is connected to the auxiliary double-row sprocket 10 through two chains 11. The distance between the two chains 11 is 2cm. The first speed-changing motor 8 drives the main double-row sprocket 9 to rotate through the first chain drive structure 12.

[0026] The inclined uniform feeding mechanism is responsible for the uniform feeding of noodles. It includes a second variable speed motor 13, a drive sprocket 14, and a driven sprocket 15. The drive sprocket 14 is mounted on the frame 1, and the driven sprocket 15 is mounted in the hopper 2. The driven sprocket 15 is higher than the drive sprocket 14. The drive sprocket 14 is connected to the driven sprocket 15 through a transmission chain 16. The transmission chain 16 is located between two chains 11. The transmission chain 16 is provided with a number of teeth 17, and all the teeth 17 are arranged side by side at equal intervals. The second variable speed motor 13 drives the drive sprocket 14 to rotate through a second chain drive structure 18.

[0027] The receiving platform 3 is located directly below the driven sprocket 15. The sensing and quantitative weighing mechanism is a linear scale 19, which is set on the receiving platform 3. It is used to sense and calculate the weight of the fresh noodles falling through the driven sprocket 15. When the weight reaches the set value, the linear scale 19 sends a signal to the first variable speed motor 8, the second variable speed motor 13 and the automatic pushing mechanism to stop the conveying and trigger the pushing action. The automatic pushing mechanism is responsible for pushing the fresh noodles that have fallen on the linear scale 19. The linear scale 19 is connected to the first variable speed motor 8, the second variable speed motor 13 and the automatic pushing mechanism respectively.

[0028] like Figure 4 As shown, the automatic feeding mechanism includes a feeding plate 20, a pulley 21, a transfer plate 22, and an electromagnetic push-pull rod 23. The upper end of the feeding plate 20 is hinged to the bottom of the hopper 2. The electromagnetic push-pull rod 23 and the pulley 21 are mounted on the hopper 2. One end of the transfer plate 22 is rotatably mounted on the hopper 2. The other end of the transfer plate 22 is connected to the middle side of the feeding plate 20 by a first steel wire 24. The first steel wire 24 is wound around the pulley 21. The end of the electromagnetic push-pull rod 23 is connected to the transfer plate 22 by a second steel wire 25. A spring seat 26 is mounted on the frame 1. A pull rod 27 is connected to the middle side of the feeding plate 20. The pull rod 27 is connected to the spring seat 26 by a spring 28.

[0029] The working process of the automatic weighing device for fresh noodle strips in this embodiment is as follows:

[0030] (1) Conveying stage: The first speed motor 8 drives the main double row sprocket 9 to rotate through the first chain drive structure 12. Under the drive of the main double row sprocket 9, the two chains 11 are conveyed to the left. The noodles 100 from the automatic noodle cutter fall on the two chains 11. At this time, the noodles 100 are symmetrically placed on the chains 11, and there is a distance between the two adjacent noodles 100. At the same time, the second speed motor 13 drives the drive sprocket 14 to rotate through the second chain drive structure 18. Under the drive of the drive sprocket 14, the conveying chain 16 is inclined to convey upward. During the conveying process, the single tooth 17 on the conveying chain 16 "catches" the single noodle transported from the chain 11. The conveying chain 16 moves upward at an incline, and the tooth 17 grabs the noodles one by one and conveys them evenly to the driven sprocket 15.

[0031] (2) Weighing stage: After the noodles pass through the driven sprocket 15, they fall freely to the linear scale 19 under the action of gravity. The linear scale 19 weighs the noodles on it. When the weight reaches the set value, the first speed motor 8, the second speed motor 13 and the electromagnetic push-pull rod 23 stop working. The push rod part of the electromagnetic push-pull rod 23 retracts. The electromagnetic push-pull rod 23 pulls the adapter plate 22 to rotate through the second steel wire 25. The adapter plate 22 pulls the push-pull plate 20 through the first steel wire 24, so that the push plate 20 rotates rapidly around the hinge point. During the rotation, the push-pull plate 20 pulls the spring 28 through the pull rod 27. The spring 28 is stretched. The rotating push-pull plate 20 pushes out the noodles on the linear scale 19. A basin or other container can be placed on the left side of the linear scale 19 in advance to catch the quantitative noodles that are pushed out.

[0032] (3) Reset stage: The linear scale 19 is powered on again, the first variable speed motor 8, the second variable speed motor 13 and the electromagnetic push-pull rod 23 are also powered on, the receiving conveying mechanism and the inclined uniform feeding mechanism start working again, the push rod part of the electromagnetic push-pull rod 23 extends, the second steel wire 25 is in the released state, the spring 28 pulls the push-pull plate 20 to reset to the vertical state, the push-pull plate 20 pulls the adapter plate 22 to rotate to the initial state through the first steel wire 24, and then measures the noodles that need to be weighed in the next round.

[0033] To prevent contamination during noodle conveying, an L-shaped baffle 29 is provided on the frame 1. The lower half of the two chains 11 is located between the baffle 29. The baffle 29 can separate the noodles from the frame 1, ensuring that the noodles only come into contact with the clean baffle 29, thus improving hygiene.

[0034] Specific embodiment 2 of the automatic weighing device for fresh noodle strips provided by this utility model:

[0035] The difference between this embodiment and specific embodiment 1 lies in the sensing quantitative weighing mechanism. In this embodiment, the sensing quantitative weighing mechanism consists of a photoelectric counter 30 and a relay, such as... Figure 5As shown, the photoelectric counter 30 is installed on the inner wall of the hopper 2, and the photoelectric counter 30 faces the driven sprocket 15. The relay is connected to the photoelectric counter 30, the first variable speed motor 8, the second variable speed motor 13 and the automatic pushing mechanism.

[0036] A photoelectric counter 30 is installed on the inner wall of the hopper 2 to detect the number of noodles falling and convert it into weight. When the set value is reached, the relay controls the conveying mechanism to pause and triggers the automatic pushing mechanism to complete the pushing action.
