Specific implementation mode

[0036] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0037] Embodiment 1: Refer to the appendix Figure 1-2 , a noodle pulling device for handmade noodle production, including a support frame 1 as the main body. Drive motors 14 are installed on both the front and rear sides of the right part of the support frame 1. Drive wheels 15 are rotatably connected to both the left and right parts of the front and rear sides of the support frame 1. A drive belt 16 is wound around the drive wheels 15 on the front side, and a drive belt 16 is also wound around the drive wheels 15 on the rear side. Uniformly distributed small bumps are provided on the outer sides of the two drive belts 16. The upper noodle stretching rods 18 are placed between the two drive belts 16, and the small bumps can separate several upper noodle stretching rods 18.

[0038] In the process of making hand-pulled noodles, after preliminary steps such as kneading and proofing the dough, the dough needs to be processed into long and thin noodle shapes. These noodles are then manually wound around two long and thin bamboo skewers. This process requires the exquisite skills and patience of the craftsman to ensure that the hand-pulled noodles are of uniform thickness, tightly wound without sticking to each other. This step is called winding the noodles; then, the craftsman holds one of the bamboo skewers, that is, the upper noodle stretching rod 18, and places it on the two drive belts 16. The other bamboo skewer, which is wound with noodles, that is, the lower noodle stretching rod 17, will naturally hang directly below it. The two bamboo skewers and the wound noodles are distributed vertically. This step is the so-called placing on the rack; finally, the craftsman holds the lower noodle stretching rod 17 and performs repeated stretching to gradually elongate the noodles to an appropriate length. This process can not only make the noodles become longer, thinner and more elastic, but also further improve their taste and texture.

[0039] In the process of making hand-pulled noodles, in order to ensure the storage of the noodles, it is necessary to dry the noodles to remove unnecessary moisture, ensure that the noodles are not prone to mildew and deterioration during storage, and at the same time maintain their taste and quality during cooking. Therefore, in this embodiment, the pulled noodles need to be dried during the production process of the noodles.

[0040] Specifically, a drying rack 11 is fixedly connected to the upper side of the support frame 1. A ventilation motor 12 is installed on the drying rack 11. The output shaft of the ventilation motor 12 is connected to a ventilation fan blade 13 through a coupling. The ventilation fan blade 13 is located above the two transmission belts 16. After the ventilation motor 12 is started, the ventilation motor 12 will drive the ventilation fan blade 13 to rotate, enhancing air flow and forming forced convection. In this way, the wind blown by the ventilation fan blade 13 can take away the moisture on the surface of the noodles, promote the evaporation of moisture, and make the noodles gradually become dry so that they can be stored for a long time.

[0041] Reference appendix Figure 2-5 In this embodiment, in order to improve the efficiency of pulling noodles to meet the needs of large-scale production, specifically, an electric telescopic rod 19 is installed on the lower left side of the support frame 1. The electric telescopic rod 19 adopts an existing telescopic push rod, that is, starting the motor can make the electric telescopic rod 19 move downward. This technology is an existing technology and will not be elaborated here. The electric telescopic rod 19 is composed of four small cylinders, and the arrangement order of these small cylinders from bottom to top is gradually tapering.

[0042] The telescopic end on the upper side of the electric telescopic rod 19 is fixedly connected to a lower pressing plate 110. The front and rear sides of the lower pressing plate 110 are both slidably connected to lower limiting plates 111. Return springs 112 are connected between the two lower limiting plates 111 and the lower pressing plate 110. The two return springs 112 are both wound around the lower pressing plate 110. The lower limiting plate 111 and the lower pressing plate 110 can form a buckle.

[0043] Since the noodles need to be quickly pulled back and forth during the stretching process to adjust the arrangement order of the gluten proteins in the noodles, making the randomly arranged protein molecules arranged into a long chain, which is called straightening the tendons in the industry. Therefore, the lower noodle stretching rod 17 needs to be clamped into the buckle, aiming to make the lower noodle stretching rod 17 in the buckle move up and down together during the up and down movement of the electric telescopic rod 19. Specifically, limiting members 113 are fixedly connected to the front and rear parts on the upper left side of the support frame 1, and inclined surfaces are provided at the lower right parts of the two limiting members 113.

[0044] Under normal conditions, when the noodle needs to be stretched, the telescopic end of the electric telescopic rod 19 extends upward to the highest point. When the craftsman places the upper noodle stretching rod 18 on the two conveyor belts 16, the front and rear ends of the lower noodle stretching rod 17 hanging below are exactly located directly below the two lower limiting plates 111. When the electric telescopic rod 19 moves downward, the electric telescopic rod 19 will drive the lower pressing plate 110 and the lower limiting plate 111 to move downward together. The downward moving lower limiting plate 111 will press on the lower noodle stretching rod 17, causing the lower noodle stretching rod 17 to also move downward, thereby stretching the noodle downward.

[0045] When the downward moving lower limiting plate 111 contacts the inclined surface of the limiting member 113, the lower limiting plate 111 will be resisted by the limiting member 113 and slide to the right. The return spring 112 will be compressed, and the lower limiting plate 111 will move away from above the lower noodle stretching rod 17. As the lower pressing plate 110 and the lower limiting plate 111 continue to move downward, the lower pressing plate 110 will contact the top of the lower noodle stretching rod 17. When the downward moving lower limiting plate 111 passes over the limiting member 113, under the elastic force of the return spring 112, the lower limiting plate 111 will slide to the left. At this time, the lower noodle stretching rod 17 will be located within the buckle formed by the lower pressing plate 110 and the lower limiting plate 111.

[0046] In this embodiment: The noodle is wound around the upper noodle stretching rod 18 and the lower noodle stretching rod 17. The upper noodle stretching rod 18 is placed on the conveyor belt 16 and remains stationary. The electric telescopic rod 19 drives the lower noodle stretching rod 17 to move downward through the lower limiting plate 111 and the lower pressing plate 110, and then slowly and uniformly stretches the noodle. During the slow stretching process, the noodle is stretched by a certain amplitude through the swinging mechanism. At this time, the swinging mechanism drives the lower noodle stretching rod 17 to move downward while pulling it slightly left and right. At the same time, due to the elasticity of the noodle, it quickly retracts after being pulled slightly. At this time, the lower noodle stretching rod 17 moves upward slightly as the noodle retracts. Repeatedly moving up and down quickly enables the noodle to achieve the effect of straightening the tendons, thereby improving the toughness of the noodle.

[0047] Reference appendix Figure 6-9 As a technical optimization solution of the present invention, the swinging mechanism includes a guide rod 23. Symmetrically distributed guide rods 23 are fixedly connected to the lower left side of the support frame 1. A connecting plate 22 is slidably connected between the two guide rods 23. Two return springs 24 are connected between the connecting plate 22 and the support frame 1. The two return springs 24 are respectively wound around the adjacent guide rods 23. Both the front and rear sides of the connecting plate 22 are slidably connected with sliding rods 2. A limiting member 25 is rotatably connected to each sliding rod 2. A small notch for placing the lower noodle stretching rod 17 is formed between the limiting member 25 and the sliding rod 2.

[0048] A clamping torsion spring 26 is connected between each limiting member 25 and the adjacent sliding rod 2. The two clamping torsion springs 26 are respectively wound around the adjacent sliding rods 2. Push blocks 28 are also slidably connected to the front and rear sides of the connecting plate 22. The left side of each push block 28 is in contact with the adjacent limiting member 25. Small cylinders are provided on the mutually remote sides of the push blocks 28. A compression spring 27 is connected between each push block 28 and the connecting plate 22. The two compression springs 27 are both wound around the connecting plate 22. The front and rear parts on the left side of the support frame 1 are fixedly connected with S-shaped sliding channels 21. The sliding rods 2 are respectively located in the adjacent S-shaped sliding channels 21. The front and rear parts on the lower left side of the support frame 1 are fixedly connected with limiting blocks 29. An inclined chute that fits the small cylinder is opened on the upper side of each limiting block 29.

[0049] In this embodiment: When the lower noodle stretching rod 17 moving downward presses on the connecting plate 22, the front and rear ends of the lower noodle stretching rod 17 will fall into the small notch formed between the limiting member 25 and the sliding rod 2. As the lower noodle stretching rod 17 moves downward, the lower noodle stretching rod 17 will press the connecting plate 22 downward, and the return spring 24 will be compressed, thereby driving the sliding rod 2, the limiting member 25, and the push block 28 to move downward together. Since the sliding rod 2 is located in the S-shaped sliding channel 21, the lower noodle stretching rod 17 located in the notch swings slightly left and right while moving downward. When the downward moving push block 28 enters the inclined chute of the limiting block 29, the push block 28 will slide leftward to push the lower end of the limiting member 25, and the compression spring 27 will be compressed. At the same time, the upper end of the limiting member 25 deflects rightward, the clamping torsion spring 26 will be twisted, and the small notch formed between the limiting member 25 and the sliding rod 2 is opened, releasing the limitation on the lower noodle stretching rod 17. At this time, the noodles have been stretched to the appropriate length.

[0050] In order to prevent the noodles from rebounding upward due to their own elasticity, it is necessary to dry the noodles after they are stretched so that the lengths of the noodles can be unified. Specifically, the front and rear parts on the lower side of the support frame 1 are fixedly connected with guide frames 114. Chutes are opened in both guide frames 114. When the small notch is opened, the lower noodle stretching rod 17 will be flush with the left entrance of the guide frame 114.

[0051] At this time, the driving motor 14 can be controlled to drive the driving wheel 15 to rotate, so that the transmission belt 16 conveys the upper noodle stretching rod 18 to the right. The lower noodle stretching rod 17 hanging below it also moves rightward synchronously along the chute of the guide frame 114. During the movement of the noodles wound between the lower noodle stretching rod 17 and the upper noodle stretching rod 18, the water on the noodles will be promoted to evaporate by the wind blown by the ventilation fan blades 13, making the noodles gradually become dry.

[0052] After the lower noodle stretching rod 17 enters the guide frame 114, the electric telescopic rod 19 can be controlled to drive the lower pressing plate 110 and the lower limiting plate 111 to move upward to the initial position. Under the elastic force of the return spring 24, the connecting plate 22 will drive the sliding rod 2, the limiting member 25, and the pushing block 28 to move upward and reset. At the same time, under the action of the compression spring 27 and the clamping torsion spring 26, the pushing block 28 will slide to the right and reset, and the upper end of the limiting member 25 will deflect to the left and reset.

[0053] In this embodiment, during the production process of hanging noodles, the last step is to cut the dried noodles into a certain length for packaging and selling. When transferring the noodles to the cutting table, the lower noodle stretching rod 17 needs to be taken out from the noodles.

[0054] Embodiment 2: Refer to Appendix Figure 10-14 As shown in FIGS. 8 and 17, the following technical solution is adopted in this embodiment: A rotary motor 32 is installed at the rear side of the rear part of the support frame 1. The output shaft of the rotary motor 32 is connected with a rotary knife 3 through a coupling. A limiting frame 31 is fixedly connected to the lower right part of the support frame 1. The height of the limiting frame 31 is slightly higher than that of the lower noodle stretching rod 17. When the lower noodle stretching rod 17 and the upper noodle stretching rod 18 drive the dried noodles to move to the right and contact the limiting frame 31, the limiting frame 31 will block the right side of the noodles. At this time, the rotary motor 32 can be controlled to drive the rotary knife 3 to rotate clockwise. The rotating rotary knife 3 will pass above the lower noodle stretching rod 17 and cut the lower part of the noodles, so that the lower noodle stretching rod 17 is separated from the noodles.

[0055] When the rotary knife 3 cuts the lower part of the noodles, under the action of the self-gravity of the lower noodle stretching rod 17, the lower noodle stretching rod 17 will fall naturally. Since the lower noodle stretching rod 17 and the upper noodle stretching rod 18 are generally made of cylindrical bamboo or pine, the cylindrical shape has the advantages of uniform stress, anti-adhesion, and easy rolling. Therefore, the fallen lower noodle stretching rod 17 will roll around on the ground, which not only increases the difficulty of collection but also causes pollution. Therefore, this embodiment needs to collect the lower noodle stretching rod 17.

[0056] Specifically, a noodle stretching rod collection box 417 is fixedly connected to the right front side of the support frame 1. Fixed plates 42 and connecting frames 418 are respectively fixedly connected to the front and rear sides of the noodle stretching rod collection box 417. A lead screw 41 is rotatably connected between the fixed plate 42 and the connecting frame 418. A guide plate 45 is fixedly connected between the fixed plate 42 and the connecting frame 418. A clamp plate 4 is threadedly connected to the lead screw 41. The clamp plate 4 slides on the guide plate 45. A servo motor 43 is installed on the fixed plate 42. The output shaft of the servo motor 43 is connected with the lead screw 41 through a coupling. The clamp plate 4 is provided with a clamping assembly for clamping the lower noodle stretching rod 17. When the servo motor 43 controls the lead screw 41 to rotate, the lead screw 41 will drive the clamp plate 4 to move back and forth on the guide plate 45, so as to drive the lower noodle stretching rod 17 to move towards the noodle stretching rod collection box 417 through the clamping assembly.

[0057] Specifically, the clamping assembly includes a clamp block 410, and the symmetrically distributed clamp blocks 410 are all slidably connected to the clamp plate 4. A tension spring 47 is connected between the side of the clamp block 410 that is away from each other and the clamp plate 4. Each tension spring 47 is wound around the clamp plate 4. In order to allow the clamping assembly to automatically clamp the lower stretched noodle rod 17 and place it into the stretched noodle rod collection box 417, an opening assembly for controlling the clamping and loosening of the clamp block 410 is provided on the limiting frame 31, and a triangular protrusion with a similar function is also provided on the connecting frame 418.

[0058] The stretching assembly includes a stretching block 44, the stretching block 44 is fixedly connected to the limiting frame 31, the right clamping block 48 and the left clamping block 49 are rotatably connected to the stretching block 44, a limiting torsion spring 46 is connected between the right clamping block 48 and the left clamping block 49, and the limiting torsion spring 46 is wound around the stretching block 44, and the right clamping block 48, the left clamping block 49, and the stretching block 44 form a triangle with each other. When the clamp plate 4 drives the clamp block 410 to move backward, the two clamp blocks 410 will be stretched open by the right clamping block 48 and the left clamping block 49, so that the clamping assembly is in an open state and is separated on the left and right sides of the lower noodle stretching rod 17, and the tension spring 47 is compressed. As the clamp block 410 continues to move backward to pass the stretching block 44, under the elastic force of the tension spring 47, the clamp block 410 clamps the front end of the lower noodle stretching rod 17.

[0059] As mentioned above, when the clamp block 410 clamping the lower noodle rod 17 moves forward with the clamp plate 4 until it contacts the triangular protrusion of the connecting frame 418, the clamp block 410 continues to be stretched open by the triangular protrusion, and the lower noodle rod 17 is released and rolls into the noodle rod collection box 417 along the guide plate 45.

[0060] Reference Figure 15-17 In the process of making noodles and stretching noodles, noodles may stick to the upper noodle stretching rod 18 and the lower noodle stretching rod 17. When the rotating knife 3 cuts the lower part of the noodles, some scraps may stick to the lower noodle stretching rod 17. Therefore, it is necessary to clean the lower noodle stretching rod 17 at the same time when collecting it. Specifically, a lifting rod 412 is slidably connected to the fixed plate 42, and an inclined block is provided on the lifting rod 412. A connecting spring 413 is connected between the lifting rod 412 and the fixed plate 42, and the connecting spring 413 is wound around the lifting rod 412. The connecting spring 413 is always in a compressed state, and a right cleaning ring 415 is rotatably connected thereto. A reset torsion spring 416 is connected between the right cleaning ring 415 and the fixed plate 42, and the reset torsion spring 416 is wound around the fixed plate 42, and the reset torsion spring 416 is always in a torsion state.

[0061] As described above, when the fixture plate 4 moves backward past the lifting rod 412, under the elastic force of the connecting spring 413, the lifting rod 412 slides downward until it no longer abuts against the right cleaning ring 415. Under the action of the reset torsion spring 416, the right cleaning ring 415 will flip upward to form a circle with the left cleaning ring 414 and fit over the lower dough stretching rod 17. When the lower dough stretching rod 17 moves forward, the scraps adhering to the lower dough stretching rod 17 will be scraped off and fall into the waste collection box 411. When the fixture plate 4 moves forward, the fixture plate 4 will squeeze the inclined block of the lifting rod 412 to make it continue to move downward, and the connecting spring 413 is stretched. When the fixture plate 4 moves forward past the inclined block, under the elastic force of the connecting spring 413, the lifting rod 412 slides upward to reset.

[0062] Similarly, when the fixture plate 4 moves backward to the initial position, the fixture plate 4 will squeeze the inclined block of the lifting rod 412 to make it move upward, compress the connecting spring 413, and the lifting rod 412 will abut against the right cleaning ring 415 to make it deflect downward and open the circle, and the reset torsion spring 416 returns to the twisted state.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
