Hand-pulled noodle splitting device

Abstract

This invention relates to a noodle-splitting device for hand-pulled noodles, comprising a frame and a stretching and sorting mechanism, a secondary stretching and conveying mechanism, and a noodle-splitting mechanism sequentially mounted on the frame. The stretching and sorting mechanism performs a primary stretching and sorting of the hand-pulled noodles using a step-by-step stretching and sorting method. The secondary stretching and conveying mechanism performs a secondary stretching and conveying of the hand-pulled noodles. The noodle-splitting mechanism is used to separate the hand-pulled noodles into individual noodles. All three mechanisms are connected to a control box. The advantages of this invention are: the stretching and sorting mechanism, through a cam linkage, achieves step-by-step stretching of the noodle column, with intermittent movement of the grooved wheel and rotating arm wheel, mimicking the one-pull-one-rebound effect of hand-pulled noodles, resulting in a gradual, step-by-step stretching effect and saving manpower. The secondary stretching and conveying mechanism simultaneously performs the final stretching of the noodle column and accurately conveys it to the correct position; the noodle-splitting mechanism mimics the up-and-down combing of noodles by hand, ensuring precise positioning, high noodle-splitting efficiency, and saving labor.

[0023] The working principle of this invention is as follows:

[0024] Operating principle of the stretching and sorting mechanism: The sorting drive motor 3 drives the sorting drive shaft 6 to rotate via the sorting drive sprocket 4 and the sorting driven sprocket 5. The sorting drive shaft 6 drives the sorting drive cam 7 to rotate. The sorting drive cam 7, through the cam connecting rod 8, drives the lifting plate 13 to move up and down on the slide rail block 14. At the same time, the sorting drive cam 7 drives the bottom of the rocker arm 16 to swing left and right. The top of the rocker arm 16, through the connecting rod 17, drives the moving plate 18 to move left and right on the slide rail 19. The sorting drive shaft 6 drives the first rotating arm wheel 11 to rotate. The first rotating arm 11 drives the sorting upper grooved wheel 9 to rotate intermittently. The sorting upper grooved wheel 9 drives the sorting upper sprocket 29 to rotate intermittently. The sorting upper sprocket 29, through the chain, drives the front drive shaft sprocket 30 and the front auxiliary drive shaft sprocket 131 to rotate intermittently. Wheel 30 drives the face rod drive chain 31 to rotate intermittently, which in turn drives the front rod 36 and the rear rod 37 to move forward intermittently. The sorting drive drive shaft 6 drives the second rotating arm wheel 12 to rotate, the second rotating arm wheel 12 drives the sorting lower groove wheel 10 to rotate intermittently, the sorting lower groove wheel 10 drives the sorting lower sprocket 21 to rotate intermittently, the sorting lower sprocket 21 drives the middle drive sprocket 22 and the middle drive rear sprocket 130 to rotate intermittently, the middle drive rear sprocket 130 drives the middle lever chain 23 to move intermittently, the middle drive sprocket 22 transmits to the middle drive shaft 114, the middle drive shaft cone wheel 116, the lower cone wheel 24, the transmission shaft 25, and the transmission upper cone wheel 26 to drive the upper shaft cone wheel 118, the upper shaft sprocket 27 to rotate intermittently, and the upper shaft sprocket 27 drives the upper lever chain 28 to move intermittently.

[0025] Description of the stretching and sorting mechanism: The various mechanisms work together to gradually lengthen the distance between the front rod 36 and the rear rod 37 while intermittently advancing, ultimately completing the stretching and sorting process of the rods placed on the rod drive chain 31. At the start of the movement, the front rod 36 and the rear rod 37 are placed side-by-side on the rod drive chain 31, with the rod 38 wrapped around them. When the rod drive chain 31 stops its intermittent movement, the lifting panel 13 lifts the rear rod 37. When the rear rod 37 is stretched to its highest point, the moving plate 18 is at an intermittent moving node, moving to the lower part of the lifting panel 13. As the lifting panel 13 reaches its highest point, it begins to descend, transferring the rear rod 37 to the moving plate 18. Subsequently, the moving plate 18 enters an intermittent backward moving node, driving the rear rod 37 backward by one station. Simultaneously, the bottom rod drive chain 31 also enters an intermittent backward moving node, moving the bottom front rod... When lever 36 moves backward one station, the front lever 36 and the rear lever 37 complete one stretching and one synchronous backward movement. This cycle is repeated 4-5 times to gradually stretch the face column 38 and gradually move the front lever 36 and the rear lever 37 backward. When the front lever 36 and the rear lever 37 are gradually stretched to the specified length and the moving panel 18 is in a backward movement resting state, the bottom middle lever chain 23 and the top upper lever chain 28 are in an intermittent motion state. Through the chain plates on their own chains, the front lever 36 and the rear lever 37 are transferred to the middle lever chain 23 and the upper lever chain 28. Finally, the sorting action of the front lever 36 and the rear lever 37 is realized on the middle lever chain 23 and the upper lever chain 28.

[0026] Description of the secondary stretching conveyor mechanism's motion: The bottom middle lever chain 23 and the top upper lever chain 28 move intermittently eight times, arranging the eight front rods 67 and rear rods 68 at the top and bottom of the chain. The turntable drive motor 39 drives the turntable 40 to rotate. The turntable 40 drives the first connecting rod 41, the upper rocker arm 42, and the lower rocker arm 43 to swing. The lower rocker arm 43, through the second connecting rod 45, pulls the first push panel 46 upward. At the same time, the rocker arm 43, through the third connecting rod 44, rotates the arm 48, and the fourth connecting rod 49 pushes the second push panel 47 downward, achieving simultaneous stretching of the eight upper rods 67 and eight lower rods 68. The top 8 rods 67 are lifted upwards to the lower end of the top chain 72, and the bottom 8 rods 68 are lifted downwards to the upper end of the bottom chain 77. The sprocket drive motor 69 rotates through the first drive sprocket 70, the first driven sprocket 71, the sprocket drive drive shaft 78, and the second drive sprocket 132. The second drive sprocket 132 drives the top chain 72 to move. The sprocket drive drive shaft 78 drives the bevel gear 119, the upper bevel gear 73, the transmission shaft 74, the lower bevel gear 75, the bevel gear 121, the driven shaft 120, and the driven sprocket 76 to rotate. The driven sprocket 76 drives the bottom chain 77 to move, so as to realize the synchronous movement of the top 8 rods 67 and the bottom 8 rods 68.

[0027] Description of the faceting mechanism's movement: Left plate 79, right plate 80, front plate 81, rear plate 82, support 83, slide rail 84, and slide rail 85 combine to form a frame structure A. The faceting lifting motor 106 drives the frame structure A up and down via the drive shaft 107, right end sprocket 108, left end sprocket 109, front lifting chain 110, and rear lifting chain 111. The faceting drive motor 86 drives the moving seat 90 to move back and forth on the first faceting slide rail 84 and the second faceting slide rail 85 via the faceting sprocket 88 and faceting chain 89. The first faceting motor 97 and the second faceting motor 98 drive the moving seat 90 to move back and forth on the first faceting slide rail 84 and the second faceting slide rail 85 via the first faceting sprocket 99 and the second faceting slide rail 85. A face sprocket 100, a drive shaft sprocket 102, and a faceting chain 101 drive the first faceting shaft 94 to rotate. The motion sequence is described as follows: The secondary stretching conveyor at the front end transports eight faceting rods 67 and 68 to a designated position. The faceting drive motor 86 drives the moving seat 90 forward. The first faceting shaft 94 inserts into the middle of the faceting column wound on the faceting rods 67 and 68. The faceting lifting motor 106 begins to drive the frame structure A downward. Simultaneously, the first faceting motor 97 and the second faceting motor 98 begin to drive the first faceting shaft 94 to rotate, achieving the faceting action of the first faceting shaft 94 moving downward while simultaneously faceting. When the first faceting shaft 94 reaches the upper part of the faceting rod 68, the faceting lifting motor 106 stops rotating downward, and the faceting drive motor 86 drives the moving seat 90 backward. The first faceting shaft 94 is pulled out from the faceting column, and the faceting lifting motor 106 rotates upward, driving the frame structure A to move upward and reset.
