Description

Technical Field

[0001] This utility model relates to the field of noodle processing technology, specifically to a fixed-length cutting device for alkaline noodles. Background Technology

[0002] In the food processing industry, the length-cutting process of alkaline noodles, a common noodle product, is crucial. Currently, the length-cutting of alkaline noodles faces the following problems: Traditional methods mostly involve manual cutting or simple mechanical cutting. Manual cutting, due to human error, makes it difficult to ensure that each noodle is of uniform length, leading to inconsistent product quality and low production efficiency, failing to meet the demands of large-scale industrial production. While some simple mechanical cutting equipment improves cutting speed to some extent, the lack of precise length control and positioning devices also results in uneven noodle lengths, wasting raw materials and impacting the product's market competitiveness. Friction during cutting: The friction between the blade and the noodle is significant, easily causing the noodles to be stretched, deformed, or even break, affecting their appearance and texture. This is especially pronounced for softer alkaline noodles. Existing cutting equipment often lacks effective solutions to this problem, making it difficult to guarantee cutting quality. Cleanliness of the production environment: The cleanliness of the cutting environment has a significant impact on product quality during the production of alkaline noodles. If there are a lot of dust, impurities, and other pollutants in the air during the cutting process, they can easily adhere to the surface of the noodles, affecting not only their hygienic quality but also potentially causing them to spoil during storage and transportation. However, many current alkaline noodle cutting machines lack effective air purification and protective measures, failing to provide a clean cutting environment. Utility Model Content

[0012] This invention provides a fixed-length cutting device for alkaline noodles, which has the following significant advantages compared to the prior art:

[0013] 1. Improve cutting accuracy and efficiency:

[0014] By installing a conveyor belt inside the support platform and mounting a cutting cylinder and cutting blade inside a U-shaped frame above the conveyor belt, combined with real-time monitoring by infrared sensors, the length of the noodles can be precisely controlled, ensuring accurate cutting. This design effectively avoids the waste and inconsistent quality problems caused by uneven lengths in traditional manual or mechanical cutting, significantly improving production efficiency and product quality.

[0015] 2. Reduce friction between the knife blade and the noodles:

[0016] The transducers, evenly distributed at the top of the cutting blade, are connected to an ultrasonic generator, introducing ultrasonic vibrations during the cutting process. These ultrasonic vibrations effectively reduce friction between the blade and the noodles, lowering cutting resistance and making the cutting process smoother. This reduces pulling and damage to the noodles, further improving cutting quality and noodle integrity.

[0017] 3. Provides a clean cooling environment:

[0018] The equipment features a protective enclosure with an air inlet and exhaust outlet on the top, forming a closed cutting environment along with an intake and exhaust fan. Inside the filter box outside the air inlet, polyester fiber filter cotton, a glass fiber filter element, and an activated carbon adsorption layer are sequentially installed, effectively filtering dust and impurities from the air and ensuring clean air entering the protective enclosure. This design not only protects the noodles from contamination during cutting but also improves the product's hygiene standards.

[0019] 4. Cooling and drying functions:

[0020] The air intake and purification mechanism inside the protective box not only provides clean air but also cools and dries the noodles. Through the combined action of the intake and exhaust fans, the airflow within the box is evenly distributed, accelerating the evaporation of moisture from the noodle surface, preventing the noodles from sticking together, and extending the product's shelf life.

[0021] 5. Modular design and easy maintenance:

[0022] All components of the equipment, such as the cutting blades, transducers, filter cotton, filter elements, and adsorption layers, are designed to be detachable, facilitating daily maintenance and replacement. In particular, the door on one side of the filter box makes replacing filter media simple and quick, greatly reducing equipment maintenance costs and time.

[0023] 6. Enhance the mobility and usability of the equipment:

[0024] The evenly spaced casters on the bottom of the base plate allow for easy movement of the equipment, adapting to different production environments and site requirements. An air pump and storage cabinet are also installed on the base plate. The air pump is connected to the cutting cylinder via an air injection pipe and is equipped with a pressure gauge to ensure stable working pressure of the cutting cylinder, further improving the equipment's reliability and ease of operation.

[0025] 7. Intelligent control:

[0026] The servo motor drives the conveyor belt, and the controller enables precise control of the cutting process, allowing for flexible adjustment of cutting speed and length to meet the production needs of noodles of different specifications. Furthermore, the use of laser ranging or image recognition technology to measure noodle length in real time further enhances cutting accuracy and automation.

[0027] In summary, this invention, through innovative design and technical means, effectively solves the problems of low cutting accuracy, high friction, and unclean environment in the prior art, and significantly improves the performance and production efficiency of the alkaline noodle fixed-length cutting equipment.

Connect the main power supply to the equipment and start the controller 12, servo motor 14, air pump 18, ultrasonic generator 25, intake fan 27 and exhaust fan 28, etc., to put them into standby mode.

[0073] noodle conveying stage

[0074] Noodle feeding: The alkaline noodles are put into the feed port 3 at one end of the protective box 4 and fall onto the conveyor belt 2.

[0075] Conveyor belt operation: When the servo motor 14 is powered on, its drive wheel drives the drive wheel of the conveyor belt 2 to rotate via the transmission belt 13. The conveyor belt 2 then starts running, conveying the alkaline noodles forward. The guide wheels on both sides of the conveyor belt 2 ensure smooth operation of the conveyor belt, reducing friction and damage to the noodles.

[0076] Noodle length detection stage

[0077] Length monitoring: When the alkaline noodles move along the conveyor belt 2 and pass under the cutting blade 21, the infrared sensors 34 installed on both sides of the inner wall of the support platform 1 start to work and detect the time it takes for the conveyor belt 2 to move the noodles in real time.

[0078] Length calculation: Based on the running speed of the conveyor belt 2 (pre-set and stored in the controller 12) and the noodle movement time detected by the infrared sensor 34, the controller 12 calculates the current length of the noodle.

[0079] noodle cutting stage

[0080] Cutting trigger: When the controller 12 calculates that the noodle length has reached the preset cutting length, it sends a command to the air pump 18 and the ultrasonic generator 25.

[0081] Cutting cylinder operation: Air pump 18 starts, inputting compressed air into cutting cylinder 9 through air injection pipe 17. The output end of cutting cylinder 9 drives mounting plate 22 and cutting blade 21 to move downward. Guide rods 23 at both ends of the top of mounting plate 22 slide within guide holes 24 of U-shaped frame 10, ensuring that cutting blade 21 moves vertically downward precisely.

[0082] Ultrasonic-assisted cutting: Simultaneously with the operation of the cutting cylinder 9, the ultrasonic generator 25 begins to work, generating high-frequency ultrasonic signals. These signals are converted from electrical energy to mechanical energy via the transducer 29, causing the cutting blade 21 to vibrate ultrasonically. This ultrasonic vibration reduces the friction between the blade and the noodles, lowering cutting resistance and making the cutting process smoother, thus reducing the pulling and damage to the noodles.

[0083] Cutting complete reset: After cutting is completed, the controller 12 controls the air pump 18 to stop supplying air, the cutting cylinder 9 retracts, and drives the cutting blade 21 to reset upward, returning to the initial position, waiting for the next cutting command.

[0084] Air purification and environmental protection stage

[0085] Air filtration and circulation: The intake fan 27 draws in outside air through the intake port 7, and the air first passes through the filter box 8. Inside the filter box 8, the polyester fiber filter cotton 31 filters out larger particles, the glass fiber filter element 32 filters out smaller particles, and the activated carbon adsorption layer 33 adsorbs harmful gases and odors in the air. The clean air that has passed through multiple stages of filtration enters the protective chamber 4, and the exhaust fan 28 exhausts the air inside the protective chamber 4 through the exhaust port 5, forming an air circulation that keeps the air inside the protective chamber 4 clean, providing a good environment for noodle cutting, while also cooling and drying the noodles to prevent them from sticking together.

[0086] Filter material replacement: Regularly open the door on one side of the filter box 8 to check and replace the polyester fiber filter cotton 31, glass fiber filter element 32 and activated carbon adsorption layer 33 to maintain the air filtration effect.

[0087] Equipment shutdown and maintenance phase

[0088] Equipment shutdown: After completing the cutting of alkaline noodles, turn off the power to the controller 12, servo motor 14, air pump 18, ultrasonic generator 25, intake fan 27 and exhaust fan 28 in sequence.

[0089] Equipment cleaning: Clean the noodle scraps remaining on the conveyor belt 2, wipe the cutting blade 21, protective box 4 and other parts to keep the equipment clean.

[0090] Equipment inspection and maintenance: Check whether the connections of each component are loose, such as the vertical plate 20 and the base plate 15, the servo motor 14 and the bracket, the cutting blade 21 and the mounting plate 22, etc.; check the wear of the cutting blade 21 and replace it if necessary; check the operating status of the air pump 18, servo motor 14 and other equipment to ensure that the equipment can be used normally next time.
