Description

Technical Field

[0001] The present invention relates to the field of noodle production equipment, and in particular to a high-quality noodle pulling and forming equipment. Background Art

[0002] Due to its good taste, convenient consumption, low price, and easy storage, noodles have always been one of the favorite staple foods of people. There are various types of noodles, thick or thin, round or flat, solid or hollow, machine-rolled noodles or hand-pulled noodles, made of pure wheat flour or flavored noodles with added auxiliary materials.

[0003] When traditional machine-made noodles are produced, taking the noodle production line with the application number: 201710866610.3 and the patent name: A Noodle Production Line as an example, the flour is stirred, fermented, and cooked, and then repeatedly rolled into a standard thin noodle blank. The thin noodle blank is cut into wet noodles by a cutting roller knife, and the wet noodles are then dried by hanging, cut, and packaged to complete the processing. The biggest feature of machine-made noodles is the short processing cycle, high production efficiency, and the ability to produce different thicknesses, round or flat types of noodles by forming with a cutting roller knife. However, limited by the process, the toughness of machine-made noodles is not as good as that of hand-pulled noodles. Therefore, high-quality noodles still adopt the pulling and forming method.

[0004] When producing so-called high-quality noodles, after the flour is stirred, cooked, and fermented, a noodle knife is used to cut the fermented noodle blank into large strips for waking up, medium strips for waking up, and small strips for waking up, and gradually pull and knead the dough-like noodle blank into a strip-shaped noodle blank as thick as a little finger. Then, the strip-shaped noodle blank as thick as a thumb is wound around two parallel noodle-supporting rods in the shape of an "8". After completion, two workers gradually pull the two noodle-supporting rods apart, so that the strip-shaped noodle blank as thick as a thumb is gradually stretched. After stretching, it is cut and packaged after natural drying. Although the output of the noodles produced in this way is not as high as that of machine-made noodles, its taste and quality are higher than those of machine-made noodles. In fact, the production method of repeatedly kneading and pulling the large-strip noodle blank replaces the traditional production method of rolling and then forming with a cutting roller knife, greatly improving the toughness and taste of the finished noodles and the quality of the noodles.

[0005] Currently, the production of high-quality hanging noodles is limited by efficiency because there are too many manual operation links during production and the degree of automation is low. Especially when the two noodle-supporting rods are separated and pulled, two workers are required to operate simultaneously. Moreover, continuous force application cannot be carried out during pulling, and pulling and relaxation need to be combined. Continuous force application will cause the noodles to break. In addition, during the pulling process, the noodles need to be dusted with powder to prevent the elongated noodles from sticking to each other. Therefore, the entire pulling process not only requires a large number of workers, but also the workers need to cooperate with each other during pulling, which requires a high level of proficiency. And powdering also needs to be carried out, with cumbersome operations and high labor intensity for workers. Therefore, to solve the problem of low production efficiency of existing high-quality hanging noodles, it is urgently necessary to optimize and improve the production links of high-quality hanging noodles, and add automated equipment on the original process level to improve the production efficiency of high-quality hanging noodles. Summary of the Invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a high-quality hanging noodle pulling and forming device, which effectively solves the problem of low production efficiency caused by the low degree of automation and large personnel demand in the production pulling link of existing high-quality hanging noodles.

[0007] The technical solution for solving the problem includes a horizontal support frame, on which two symmetrically arranged pulling units are installed. The pulling unit includes a U-shaped plate slidably installed on the support frame and opening downward. A rack along its length direction is provided at the upper end of the support frame. A gear meshing with the rack is rotatably installed inside the U-shaped plate. Each U-shaped plate is provided with a motor for driving the gear to rotate. The two motors rotate synchronously and in opposite directions. At the inner side of each of the two lower ends of each U-shaped plate, a connecting rod is rotatably installed. The two connecting rods are parallel and synchronously driven by the gear. A positioning cylinder is fixed at the free end of each connecting rod. The two positioning cylinders on the same U-shaped plate are coaxial and have opposite openings. A horizontal tray is provided below the support frame. The tray can move up and down. During the process that the connecting rod rotates downward from the vertical state and gradually tends to the horizontal state, the tray moves up. During the process that the connecting rod rotates downward from the horizontal state and gradually tends to the vertical state, the tray moves down. The tray does not contact the positioning cylinder during the whole process.

[0008] Furthermore, the support frame is composed of two parallel support square rods. The brackets on the two support square rods are fixed into a whole through connecting rods. Legs are provided at both the left and right ends of the support frame. A rack is fixed at the upper end of each support rod.

[0009] Furthermore, a horizontal chute is provided on each of the front and rear side walls of the support frame. A slider that can slide in the chute is fixed on the U-shaped plate.

[0010] Further, a first pulley fixed to a warp beam and a gear is rotatably installed on the outer side of each side wall of the U-shaped plate. A second pulley is coaxially fixed on the rotation central axis of the connecting rod. The first pulley and the second pulley are connected by a belt. A third pulley is coaxially fixed on the output shaft of the motor. A fourth pulley is coaxially fixed on one of the first pulleys. The third pulley and the fourth pulley are connected by a belt.

[0011] Further, a retaining disc is slidably installed in the positioning cylinder, and the retaining disc is connected to the bottom of the positioning cylinder by a spring.

[0012] Further, a plurality of electric cylinders are provided at the lower end of the tray, and the electric cylinders are electrically connected to the motor through a PLC control unit.

[0013] By imitating the force application process of manually pulling noodles, the noodles are gradually stretched under a variable force, avoiding the problem that the noodles are easily broken by traditional constant force pulling. At the same time, during the pulling process, the powdering of the stretched part of the noodles can be automatically realized, reducing the problem of adhesion. The whole operation is automated, reducing the labor cost and effectively improving the efficiency of noodle pulling. Description of the Drawings

[0019] The following further describes the specific embodiments of the present invention in detail with reference to the drawings.

[0020] By Figures 1 to 5It can be seen that the present invention includes a horizontal support frame 1, on which two symmetrically arranged traction units are installed. The traction unit includes a U-shaped plate 2 slidably installed on the support frame 1 and opening downward. In order to realize the sliding installation of the U-shaped plate 2 on the support frame 1, a horizontal chute 9 is provided on each of the front and rear side walls of the support frame 1. A slider 10 that can slide in the chute 9 is fixed on the U-shaped plate 2. A rack 3 is provided at the upper end of the support frame 1 along its length direction. In order to realize the fixation and installation of the support frame 1, the support frame 1 is composed of two parallel support square rods, and the two support square rods of the support frame 1 are fixed into a whole by a connecting rod. Legs 8 are provided at both the left and right ends of the support frame 1. A rack 3 is fixed at the upper end of each support rod. A gear 4 meshing with the rack 3 is rotatably installed in the U-shaped plate 2. A motor for driving the gear 4 to rotate is provided on each U-shaped plate 2, and the two motors rotate synchronously and in opposite directions. A connecting rod 5 is rotatably installed on the inner side of each of the two lower end parts of each U-shaped plate 2. In order to facilitate driving, a first pulley 11 fixed to the gear 4 by a shaft is rotatably installed on the outer side of the side wall of each U-shaped plate 2. A second pulley 12 is coaxially fixed on the rotation center shaft of the connecting rod 5. The first pulley 11 and the second pulley 12 are connected by a belt. A third pulley 13 is coaxially fixed on the output shaft of the motor. A fourth pulley 14 is coaxially fixed on one of the first pulleys 11. The third pulley 13 and the fourth pulley 14 are connected by a belt. The two connecting rods 5 are kept parallel and are synchronously driven by the gear 4. A positioning cylinder 6 is fixed at the free end of each connecting rod 5. In order to realize the installation of the support surface rod in the positioning cylinder 6, a stop disk is slidably installed in the positioning cylinder 6, and the stop disk is connected to the bottom of the positioning cylinder 6 by a spring. The two positioning cylinders 6 on the same U-shaped plate 2 are coaxial and have opposite openings. A horizontal tray 7 is provided below the support frame 1. In order to realize the up and down driving of the tray 7, a plurality of electric cylinders 15 are provided at the lower end of the tray 7. The electric cylinders 15 are electrically connected to the motors through a PLC control unit. The tray 7 can move up and down. During the process that the connecting rod 5 rotates downward from the vertical state and gradually tends to the horizontal state, the tray 7 moves up. During the process that the connecting rod 5 rotates downward from the horizontal state and gradually tends to the vertical state, the tray 7 moves down. During the whole process, the tray 7 does not contact the positioning cylinder 6.

[0021] Specific working process of the present invention: When the device is in use, the motor drives two pulling units to move closer to each other, causing the free ends of the connecting rods 5 on the two U-shaped plates 2 to approach each other. At this time, the two noodle support rods with dough pieces are respectively fixed in the corresponding positioning cylinders 6. The retaining disks flexibly connected by springs in the positioning cylinders 6 can limit the two ends of the noodle support rods, preventing the noodle support rods from detaching during the pulling process, and at the same time facilitating manual installation and unloading. After the installation is completed, the two pulling units move in the opposite direction under the synchronous drive of the motor, and the connecting rods 5 on the pulling units on both sides rotate synchronously in the opposite direction. During this movement process, the motor drives the gear 4 to rotate through the third belt pulley 13 and the fourth belt pulley 14. The gear 4 meshes with the rack 3. The rotation of the gear 4 enables the two pulling units to rotate synchronously in the opposite direction during this rotation process. At the same time, the rotation of the gear 4 drives the connecting rod 5 to rotate through the first belt pulley 11 and the second belt pulley 12.

[0022] During this driving process, the pulling units move at a constant speed in the opposite direction under the drive of the motor. This movement can achieve the forward pulling of the noodles at a constant speed. At the same time, when the connecting rods 5 on both sides rotate and their free ends move away from each other, the forward pulling of the noodles can be achieved at a variable speed. The superposition of the two forward pullings accelerates the pulling of the noodles. When the connecting rods 5 on both sides rotate to make their free ends approach each other, the noodles are reversely relaxed at a variable speed. When the value of this reverse relaxation is greater than the value of the constant pulling maintained by the pulling units under the drive of the motor, the noodles will no longer be tightened in this state. At this time, the noodles droop downward in the middle under the action of gravity. During the drooping process, when the connecting rod 5 rotates downward from the vertical state and gradually tends to the horizontal state, the electric cylinder 15 drives the tray 7 to move upward to support the noodles drooping in the middle. The dry powder thinly sprinkled in the tray 7 is supported and dusted while falling onto the tray 7 in the middle of the noodles. After completion, with the continuous rotation of the motor, under the action of the PLC control unit, the electric cylinder 15 retracts and the tray 7 moves downward. The entire process will not cause contact between the positioning cylinder 6 and the tray 7. As the free ends of the connecting rods 5 on both sides move away from each other again, the connecting rod 5 rotates to drive the noodles to be pulled forward at a variable speed again. The noodles are tightened and stretched again. This cycle is repeated to automatically realize the gradual stretching of the noodles while completing the dusting on the surface of the stretched noodles. Finally, after the noodles are stretched, the noodle support rods are removed at both ends of the support frame 1 and enter the next drying link, and the motor drives the pulling units to reset.

[0023] The advantages of this device are as follows:

[0024] 1. By imitating the force application process of manually pulling noodles, this device enables the noodles to be gradually stretched under variable forces, avoiding the problem that traditional constant force pulling easily causes the noodles to break. At the same time, during the pulling process, the dusting of the stretched part of the noodles can be automatically realized, reducing the problem of adhesion. The entire operation is automated, reducing labor costs and effectively improving the efficiency of noodle pulling.

[0025] 2. The uniform reverse movement of the U-shaped plate 2 provides a constant-speed forward pulling force for the pulling of the noodles, which is defined as A. When the two side connecting rods 5 move away from each other, a variable-speed forward pulling force for the noodles is provided and defined as B. When the two side connecting rods 5 move closer to each other, a variable-speed reverse relaxation for the noodles is provided, defined as C. Therefore, during the entire periodic motion process, it is divided into two processes: A + B and A - C. When A + B and A - C are positive values, the noodles are pulled, and the greater the value, the greater the pulling force. When A - C is positive, it is pulling; when A - C is negative, the noodles relax and droop. When A - C is negative, the electric cylinder 15 drives the tray 7 to move upward and approach the drooping noodles at this time, and the stretched part of the noodles is dusted on the tray 7.

[0026] 3. The structure of this device is ingenious, with low production costs, convenient to use, conducive to large-scale use and promotion. It can greatly improve the production efficiency of high-quality hanging noodles, and replace the laborious manual operation links in the traditional process with automated equipment, which not only improves production efficiency but also effectively reduces the investment in labor costs and reduces the labor intensity of workers.
