Description

Technical Field

[0001] The present invention relates to the field of vermicelli processing, and specifically relates to a fixed-length cutting device and method for an instant vermicelli extruder. Background Art

[0002] The cutting device of the traditional vermicelli extruder actually uses a cutting knife to extrude the vermicelli, that is, the vermicelli breaks after being extruded. However, because the vermicelli has a certain viscosity when it is not dried, the broken vermicelli crumbs will stick to the cutting knife. At this time, when the cutting device continues to operate, the vermicelli crumbs will be air-dried and solidified on the cutting surface of the cutting knife. Subsequently, when the cutting knife continues to cut the subsequent vermicelli, the subsequent vermicelli will be contaminated by the air-dried vermicelli crumbs, thereby affecting the quality of the subsequent vermicelli. At the same time, after the air-dried vermicelli crumbs adhere to the cutting knife, the cleaning difficulty of the cutting knife will increase, thereby affecting the overall working efficiency of the equipment.

[0003] At the same time, because the traditional cutting device is mostly fixedly installed beside the output end of the extruder, when cutting the same batch of extruded vermicelli, the cutting knife at a fixed position will cause a slight deviation in the cutting position, and it cannot meet the requirement of fixed-length cutting (that is, there will be an error in the length between the vermicelli that first contacts the cutting knife and the vermicelli that last contacts the cutting knife in the same batch of vermicelli). At this time, the operator needs to perform secondary processing on the vermicelli later to prevent difficulties in packaging due to inconsistent vermicelli lengths during the subsequent automatic packaging process. During this process, the secondary processing requires additional time and manpower, which may cause delays in the production process.

[0004] Therefore, we need to design a fixed-length cutting device for the vermicelli extruder to solve the above problems. Summary of the Invention

[0021] A method for using a fixed-length cutting device for an instant vermicelli extruder, further comprising the following steps:

[0022] S1: The operator starts the extruder first, and the extruder extrude the vermicelli downward through the material tray. After the vermicelli is extruded, the operator adjusts the output efficiency of the synchronization mechanism according to the extrusion speed of the vermicelli;

[0023] S2: After the homology mechanism is activated, it will drive the lifting platform to move at the same speed as the extrusion speed of the vermicelli. At this time, the lifting platform and the vermicelli remain relatively stationary;

[0024] S3: Finally, the cutting mechanism is activated and the vermicelli is cut to a fixed length by a steel wire.

[0025] The beneficial effects of the present invention compared with the prior art are as follows:

[0026] Firstly: This device uses a steel wire to cut the vermicelli. Compared with the traditional cutting by a cutter, the steel wire in this device can vibrate at a high speed along its own axis direction, thereby achieving uniform cutting of the vermicelli, reducing burrs and deformation at the cut of the vermicelli. At the same time, compared with the cutter, less vermicelli scraps adhere to the steel wire, greatly improving the appearance quality and product grade of the vermicelli;

[0027] Secondly: This device uses an atomizer and a blower in cooperation to clean the steel wire, ensuring that after the steel wire cuts the vermicelli, the atomizer and the blower can cooperate to soften and clean the remaining vermicelli scraps on the steel wire, preventing the vermicelli scraps from drying and solidifying and sticking to the cutter. The removed vermicelli scraps will be sucked away by a suction machine, improving the hygiene level of the vermicelli during the cutting process;

[0028] Thirdly: This device uses a homology mechanism to ensure that when the steel wire cuts the same batch of vermicelli, the steel wire can synchronously adjust the cutting position along with the extrusion of the vermicelli, ensuring that after the vermicelli is cut, the cut vermicelli can be cut to a fixed length, improving the quality of the vermicelli.

[0042] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0043] Refer to Figures 1 to 11 , a fixed - length cutting device for an instant - noodle - like vermicelli extruder, which includes a frame 5 fixedly connected to the upper end of a workbench 8 and an extruder 1 fixedly connected to the upper end of the frame 5, and further includes:

[0044] A material tray 2, coaxially and fixedly connected to the output end of the extruder 1;

[0045] Two first slide rails 6, fixedly connected to one side of the frame 5 close to the extruder 1;

[0046] A lifting platform 7, arranged below the extruder 1 and slidably connected to the two first slide rails 6;

[0047] A homology mechanism 9, connected to the frame 5 and the output end thereof is connected to the lifting platform 7;

[0048] Cutting mechanism 15, connected to the lifting platform 7, includes a transfer plate 23, a steel wire 24, two wire seats 22, two self-cleaning mechanisms 26 and two wire racks 25. The transfer plate 23 is fixedly connected to the lower end of the lifting platform 7. The two wire seats 22 are arranged on the side of the transfer plate 23 away from the lifting platform 7 (refer to Figure 3 ), the two wire racks 25 are symmetrically arranged coaxially at the lower end of the transfer plate 23 and are respectively slidably connected to the two wire seats 22. The two ends of the steel wire 24 are respectively fixedly connected to the two wire racks 25. The two self-cleaning mechanisms 26 are respectively arranged on both sides of the steel wire 24 and are fixedly connected to the lower end of the transfer plate 23.

[0049] For the convenience of understanding, Figure 7 This is an inverted view of the cutting mechanism 15 in this device. When the device is running, the operator first starts the extruder 1, and the extruder 1 will extrude the vermicelli downward through the material tray 2. After the vermicelli is extruded, the operator adjusts the output efficiency of the synchronization mechanism 9 according to the extrusion speed of the vermicelli. Subsequently, the synchronization mechanism 9 starts and drives the lifting platform 7 to move. The lifting platform 7 will move at the same speed as the extrusion speed of the vermicelli. At this time, the lifting platform 7 and the vermicelli remain relatively stationary. After the cutting mechanism 15 starts, it will drive the steel wire 24 to cut the vermicelli (combined with Figure 3 and Figure 7 ), and the steel wire 24 after the cutting work is completed will be cleaned by the self-cleaning mechanism 26, thereby avoiding the subsequent vermicelli being contaminated during the cutting process.

[0050] In order to prevent the uncut vermicelli from being contaminated by external dust during the movement of the lifting platform 7, the following features are specifically set:

[0051] On the side of the output end of the extruder 1 close to the lifting platform 7, there is a corrugated cover 4 (refer to Figure 3 ), the upper end of the corrugated cover 4 is fixedly connected to the extruder 1, and the lower end is fixedly connected to the upper end of the lifting platform 7. The material tray 2 is formed with a number of material holes 3 arranged in an equiangular array along the circumferential direction. The diameter of the material holes 3 is 1.5 mm, and the number is 380. During the movement of the lifting platform 7, the corrugated cover 4 will expand and contract with the movement of the lifting platform 7 to facilitate the protection of the uncut vermicelli and prevent these vermicelli from being contaminated by external dust. At the same time, after testing, the vermicelli produced by the material tray 2 with a diameter of 1.5 mm and a number of 380 has the best quality.

[0052] In order to supplement the specific structure of the self-cleaning mechanism 26, the following features are specifically set:

[0053] The self-cleaning mechanism 26 further includes a cleaning frame 27, an atomizer 28, a fan 29 and a number of air nozzles 30. The cleaning frame 27 is fixedly connected to the lower end of the transfer plate 23 (refer to Figure 5), the fan 29 is fixedly connected to the lower end of the cleaning frame 27. A plurality of air nozzles 30 are arranged at equal intervals along the long side direction of the cleaning frame 27 on the side close to the transfer plate 23. The air nozzles 30 are fixedly connected to the output end of the fan 29. The atomizer 28 is arranged on the side of the plurality of air nozzles 30 away from the steel wire 24 and is fixedly connected to the cleaning frame 27. The output end of the atomizer 28 is arranged in the same direction as the output ends of the plurality of air nozzles 30. When cleaning the steel wire 24, the atomizer 28 sprays fine water mist. Since the fan 29 also outputs gas to the steel wire 24 through the plurality of air nozzles 30, the fine water mist will be blown by these gases and cooperate with the gases to clean the fan debris attached to the steel wire 24, preventing the fan debris from solidifying on the steel wire 24 and affecting the subsequent cutting work of the fans.

[0054] To facilitate the collection of the debris washed off and prevent the debris from flying around and affecting the quality of the fans, the following features are specifically set:

[0055] The self-cleaning mechanism 26 further includes a flow guide cover 31 and a suction machine 32. Two flow guide covers 31 are arranged on the side where the two cleaning frames 27 are close to each other (refer to Figure 6 ), and two suction machines 32 are respectively arranged on the side of the transfer plate 23 close to the lifting platform 7 (refer to Figure 7 ). The output ends of the two suction machines 32 are respectively communicated with the upper ends of the two flow guide covers 31. After the fan debris attached to the steel wire 24 is cleaned, the flow guide cover 31 will block these fan debris, and after the suction machine 32 is started, it will suck and process these blocked fan debris to prevent these debris from flying and re-attaching to the fans cut to a fixed length below.

[0056] To supplement the specific structure of the synchronization mechanism 9, ensure that the steel wire 24 can move synchronously with the fans, and thus realize the fixed-length cutting of the fans, the following features are specifically set:

[0057] The synchronization mechanism 9 includes a first motor 10, a first bevel gear 11, a second bevel gear 12, a screw 13 and a screw base 14. The screw base 14 is fixedly connected to the lifting platform 7 (refer to Figure 2 ). The upper end of the screw 13 is rotatably connected to the machine frame 5, and the lower end is rotatably connected to the workbench 8. The screw 13 is threadedly connected to the screw base 14. The second bevel gear 12 is rotatably connected to the lower end of the workbench 8 through a bevel gear frame. The second bevel gear 12 is coaxially fixedly connected to the lower end of the screw 13. The first bevel gear 11 is rotatably connected to the bevel gear frame and meshes with the second bevel gear 12. The first motor 10 is fixedly connected to the lower end of the workbench 8 and the output end is coaxially fixedly connected to the first bevel gear 11. After the first motor 10 is started, the first motor 10 drives the second bevel gear 12 to rotate through the first bevel gear 11. The second bevel gear 12 drives the screw base 14 to move through the screw 13. When the screw base 14 moves, it drives the lifting platform 7 to move. When the lifting platform 7 moves, it is limited by the two first slide rails 6.

[0058] During the process of extruding vermicelli, the lifting platform 7 will move at the same speed as the extrusion speed of the vermicelli. At this time, the lifting platform 7 and the vermicelli remain relatively still, ensuring that the steel wire 24 can cut the same batch of vermicelli into a fixed length. After each cutting, since the steel wire 24 moves from one end of the lifting platform 7 to the other end, the lifting platform 7 will not move in the horizontal direction before the next time the steel wire 24 cuts the vermicelli, thereby preventing the steel wire 24 from mistakenly cutting the vermicelli during the upward movement of the lifting platform 7.

[0059] In order to drive the steel wire 24 to move so that the steel wire 24 can cut the vermicelli, the following features are also specifically set:

[0060] The cutting mechanism 15 also includes a driving motor 16, a driving pulley 17, two driven pulleys 18, two screw rods 19, two screw seats 20 and two positioning seats 21. The driving motor 16 is fixedly connected to one end of the lifting platform 7 through a motor frame (refer to Figure 7 ), the driving pulley 17 is coaxially connected to the output end of the driving motor 16, the two driven pulleys 18 are respectively rotatably arranged on both sides of the driving motor 16 and are respectively connected to the driving pulley 17 through belts, and the two positioning seats 21 are respectively connected to one end of the lifting platform 7 close to the transfer plate 23 (reference Figure 3 ), the transfer plate 23 is fixedly connected to the two positioning seats 21, and the two screw rods 19 are respectively rotatably arranged on one side of the transfer plate 23 close to the lifting platform 7, and the two screw rods 19 are respectively coaxially fixedly connected to the two driven pulleys 18 (reference Figure 7 ), the two thread holders 20 are respectively threadedly connected with the two threaded rods 19 (reference Figure 3 ), the two wire seats 20 are respectively slidably connected with the two positioning seats 21, and the two wire seats 22 are respectively fixedly connected with the two wire seats 20. After the active motor 16 is started, the active motor 16 will drive the two driven pulleys 18 to rotate through the active pulley 17, and the two driven pulleys 18 will drive the two wire seats 20 to move through the two screw rods 19. During the movement of the two wire seats 20, the two positioning seats 21 are used to limit the position, and the two wire seats 20 will drive the two wire racks 25 to move through the two wire seats 22. The two wire racks 25 will drive the steel wires 24 fixedly connected thereto to move in the horizontal direction. When the steel wires 24 move, the vermicelli will be cut to a fixed length. Compared with the traditional cutter, the steel wires 24 can reduce the burrs and deformation at the incision of the vermicelli, and there are fewer vermicelli shavings attached to the steel wires 24, which greatly improves the appearance quality and product grade of the vermicelli.

[0061] In order to drive the steel wire 24 to reciprocate along its own axis, the following features are also specifically provided:

[0062] The cutting mechanism 15 further includes a third motor 34, a cam 35, a connecting block 33, a tension spring 38, two sliding plates 36 and four sliding guide rods 39. The third motor 34 is fixedly connected to one side of a wire seat 22 away from the transfer plate 23 through a motor bracket (refer to Figure 10 ), the cam 35 is coaxially fixedly connected to the output end of the third motor 34, the two sliding plates 36 are respectively arranged on the sides of the two wire seats 22 away from each other, the connecting block 33 is fixedly connected to the sliding plate 36 close to the third motor 34, the connecting block 33 abuts against the outer edge of the cam 35, the two sliding plates 36 are respectively rotatably connected to the two wire frames 25, one sliding guide rod 39 is fixedly connected to each end of each sliding plate 36, the sliding guide rod 39 is slidably connected to the wire seat 22, the tension spring 38 is coaxially sleeved on the wire frame 25 close to the third motor 34, one end of the tension spring 38 is fixedly connected to the wire seat 22 close to the third motor 34, and the other end is fixedly connected to the sliding plate 36 close to the third motor 34. When the wire seat 20 moves, starting the third motor 34 will drive the cam 35 to rotate. After the cam 35 rotates, it will push the sliding plate 36 in contact with it through the connecting block 33 to move. After the sliding plate 36 moves, it will be limited by the corresponding sliding guide rod 39. At the same time, when the sliding plate 36 moves, it will also drive the steel wire 24 to reciprocate along its own axis direction through the wire frame 25. During the reciprocating movement of the steel wire 24, the vermicelli can be quickly cut. When the wire frame 25 close to the third motor 34 moves, it will be reset through the tension spring 38, realizing the high-speed reciprocating vibration of the steel wire 24.

[0063] Compared with the working mode of traditional cutting knives, when traditional cutting knives cut vermicelli, due to the large contact area between the blade and the vermicelli, it is easy to produce extrusion and tearing effects on the vermicelli, resulting in problems such as deformation, fracture or internal structure damage of the vermicelli near the cut. The diameter of the steel wire 24 is relatively thin, and the contact area with the vermicelli is small, so the damage to the vermicelli during the cutting process is small, and the original quality and taste of the vermicelli can be better maintained.

[0064] In order to buffer and limit the movement of the wire frame 25 away from the third motor 34, the following features are specifically set:

[0065] The cutting mechanism 15 further includes a spring 37. The spring 37 is coaxially sleeved on the wire frame 25 away from the third motor 34 (refer to Figure 2 、 Figure 3 and Figure 11 ), one end of the spring 37 is fixedly connected to the wire seat 22 away from the third motor 34, and the other end is fixedly connected to the sliding plate 36 away from the third motor 34. When the steel wire 24 moves, the sliding plate 36 away from the third motor 34 will be reset and buffered through the spring 37 to ensure that the steel wire 24 will not be slack due to the force on one end during the movement of the steel wire 24.

[0066] In order to enable the two wire frames 25 to rotate during movement, and further ensure that the steel wire 24 fixedly connected to the wire frame 25 can also rotate, the following features are specifically set:

[0067] The cutting mechanism 15 further includes two sliding racks 40, two sliding gears 41, two third bevel gears 42 and two fourth bevel gears 43. The two third bevel gears 42 are rotatably connected to the side of the two wire seats 22 close to each other through a bevel gear frame (refer to Figure 8 ), the two third bevel gears 42 are respectively key-connected to the two wire frames 25, the two fourth bevel gears 43 are respectively rotatably connected to the corresponding bevel gear frames and meshed with the two third bevel gears 42, the two sliding gears 41 are respectively rotatably connected to the corresponding bevel gear frames through tooth seats, the two sliding gears 41 are respectively coaxially fixedly connected to the two fourth bevel gears 43, the two sliding racks 40 are respectively slidably connected to the two wire seats 22 and meshed with the two sliding gears 41, and the two sliding racks 40 are respectively fixedly connected to the adjacent sliding guide rods 39. When the two wire frames 25 reciprocate along the axial direction of the steel wire 24, the wire frame 25 will drive the sliding guide rod 39 to move through the sliding plate 36 (refer to Figure 10 ), after the sliding guide rod 39 moves, it will drive the sliding gear 41 to rotate through the sliding rack 40 (refer to Figure 8 ), after the sliding gear 41 rotates, it will drive the third bevel gear 42 to rotate through the fourth bevel gear 43, and the third bevel gear 42 will drive the wire frame 25 key-connected to it to rotate. As can be seen from the previous text, at this time, when the wire frame 25 moves along its own axial direction, the wire frame 25 will also rotate along its own circumferential direction, that is, the steel wire 24 can reciprocally vibrate and rotate during the lateral movement. During this process, in order to ensure that the two wire frames 25 rotate synchronously and in the same direction, the installation positions of the two sliding racks 40 (refer to Figure 11 ).

[0068] When the rotating steel wire 24 cuts the vermicelli, it can apply the cutting force more evenly, avoiding the problem of uneven cut edges that may occur in traditional fixed-angle cutting, making the cut edges of the vermicelli neater, which is beneficial to subsequent packaging and processing. At the same time, the rotation of the steel wire 24 can reduce the friction and adhesion between it and the vermicelli, and reduce the resistance during the cutting process. That is, under the drive of the same power, the steel wire 24 can cut more smoothly, improve the cutting speed, and thus improve the overall cutting efficiency.

[0069] A method for using a fixed-length cutting device for an instant vermicelli extruder further includes the following usage steps:

[0070] S1: The operator first starts the extruder 1, and the extruder 1 will extrude the vermicelli downward through the material tray 2. After the vermicelli is extruded, the operator adjusts the output efficiency of the synchronization mechanism 9 according to the extrusion speed of the vermicelli;

[0071] S2: After the homology mechanism 9 is started, it will drive the lifting platform 7 to move at the same speed as the extrusion speed of the vermicelli. At this time, the lifting platform 7 and the vermicelli remain relatively stationary.

[0072] S3: Finally, the cutting mechanism 15 is started and the vermicelli is cut to a fixed length by the steel wire 24.

[0073] The working principle of this device is that when the device is running, the operator first starts the extruder 1, and the extruder 1 will extrude the vermicelli downward through the material tray 2.

[0074] After the vermicelli is extruded, the operator adjusts the output efficiency of the first motor 10 according to the extrusion speed of the vermicelli. After the first motor 10 is started, the first motor 10 will drive the lifting platform 7 to move. That is, during the extrusion process of the vermicelli, the lifting platform 7 will move at the same speed as the extrusion speed of the vermicelli. At this time, the lifting platform 7 and the vermicelli remain relatively stationary, ensuring that the steel wire 24 can cut the same batch of vermicelli to a fixed length. And after each cut, since the steel wire 24 moves from one end of the lifting platform 7 to the other end, the steel wire 24 will not move horizontally before the lifting platform 7 moves upward until the next time the steel wire 24 cuts the vermicelli, preventing the steel wire 24 from wrongly cutting the vermicelli during the upward movement of the lifting platform 7.

[0075] During the cutting process, the lifting platform 7 and the vermicelli remain relatively stationary, and the relative stationary state ensures that at the moment of cutting, the distance from the extrusion point to the cutting point of the vermicelli is always fixed, providing the necessary position condition for fixed-length cutting. Subsequently, the distance when the steel wire 24 moves from one end of the lifting platform 7 to the other end is fixed and precisely controllable. When the steel wire 24 moves to a preset specific position, the steel wire 24 will perform a cutting operation on the vermicelli. Since the lifting platform 7 and the vermicelli are relatively stationary and the moving stroke of the steel wire 24 is fixed, the vermicelli is cut at the same position each time, thus ensuring that the length of the vermicelli cut each time is exactly the same. During the processing, the above process is repeated, thereby realizing the precise "fixed-length" cutting of the vermicelli.

[0076] During the movement of the steel wire 24, when the third motor 34 is started, it will drive the steel wire 24 to perform reciprocating vibration along its own axis. The steel wire 24 can quickly cut the vermicelli during the reciprocating movement. When the wire frame 25 close to the third motor 34 moves, it will be reset through the tension spring 38 to realize the high-speed reciprocating vibration of the steel wire 24. At the same time, the wire frame 25 can also perform reciprocating rotation during the reciprocating movement. At this time, the steel wire 24 can apply a more uniform cutting force to the vermicelli compared with the traditional cutting tool, avoiding the problem of uneven cut edges that may occur in traditional fixed-angle cutting, making the cut edges of the vermicelli neater. At the same time, the rotating steel wire 24 can reduce the adhesion amount of vermicelli scraps and reduce the difficulty of subsequent cleaning.

[0077] When the steel wire 24 moves to one end of the transfer plate 23, the atomizer 28 will spray out fine water mist. Since the fan 29 will also output gas to the steel wire 24 through a number of air nozzles 30, the fine water mist will be blown by these gases and cooperate with the gases to clean the vermicelli debris attached to the steel wire 24. After the vermicelli debris attached to the steel wire 24 is cleaned, the flow guide cover 31 will block these vermicelli debris, and after the suction machine 32 is started, it will suck and process these blocked vermicelli debris to prevent these debris from flying and reattaching to the vermicelli cut to a fixed length below.

[0078] The above embodiments only express one or several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
