The working mode of the pasta machine is as follows: Mixing stage: Put the flour and water into the stirring cup, the motor drives the stirring rod to rotate, mix and mix the flour and water, and when it reaches the set level, enter the exit stage; : The motor reversely drives the stirring rod to push the flour into the extrusion nozzle. Under the pushing action of the screw, the flour is extruded from the exit die to complete the processing.

However, the existing noodle machine has the following technical problems: if the user forgets to add water during the processing, the screw continues to push the flour to the front end, and the flour cannot be squeezed out by the exit die in time, resulting in the extrusion nozzle. The pressure at the front end continues to increase, which in turn causes the explosion of the extrusion cylinder, the end cover or the exit die. The continuous increase of the pressure also increases the output power of the motor, causing the current to continuously rise and the temperature of the motor to rise. , will burn the motor. In the existing noodle machine, if the exiting die is blocked, the screw will continue to feed, so that the pressure at the front end of the screw and the extrusion nozzle is getting larger and larger, and eventually the extrusion nozzle or the extrusion die is severely cracked. It will also cause harm to the user.

In addition, in the prior art, since the difference in the diameter of the screw is small, the pressing gap is uniform, and the force of the dough in the pressing chamber does not change much, so the dough entering the pressing chamber is not sufficiently squeezed. The process is pushed to the molding die for extrusion molding, so that the quality of the noodles during extrusion molding depends on the number of faces entering the face, and the amount of the face at the face is random, and cannot be guaranteed to enter the extrusion. The continuity of the dough in the pressure chamber, and the dough entering the dough tube from the stirring cup is only stirred, and the dough is not fully squeezed in the pressing chamber, which is relatively fluffy, resulting in a squeeze from the squeeze head The extruded shaped noodles have poor toughness and gluten, and the noodles are easily broken from the middle, and the taste and appearance of the noodles are poor. In the prior art, the thread is usually set to one. If a larger pitch is set, the screw requires a large torque, the power requirement of the pasta machine is high, and the probability of screw damage is increased; if a small pitch is set , the extrusion speed is slow, affecting the processing efficiency of the pasta machine.

Thus, a feature defining "first" or "second" may explicitly or implicitly include one or more of the features, using "the first When "one", it does not necessarily contain the corresponding "second" feature.

The beneficial effects of the present disclosure are that

1. By providing the safety protection structure, when the screw is formed in the extrusion surface, or during abnormal processing such as squeezing dry flour, if the front end pressure is too large, the material can be prevented from entering between the screw and the end cover. Or, the material between the screw and the end cap is discharged to the rear end of the screw to reduce the material pressure at the front end of the screw, which can effectively prevent the crushing surface component caused by the continuous feeding of the screw in the working process of the noodle machine.

2. The safety protection structure is configured as a pressure relief rib, so that a certain pressure difference is formed before and after the pressure relief rib, and when the pasta machine fails to come out normally, the material is intercepted at the pressure relief rib, The pressure formed by the material at the front end of the pressure relief rib blocks the back end material from entering the front of the pressure relief rib through the pressure relief rib, so that the front end pressure of the screw is always maintained within a safe range, thereby ensuring the safety of the pasta machine. Prevent the pasta machine from being damaged. At the same time, if the flour enters the extrusion chamber, under the action of the pressure relief ribs, the flour is blocked by the pressure relief ribs, and the continuity cannot be formed, which further blocks the possibility of entering the extrusion die, ensuring the squeeze. The die does not get too much pressure or even bursts due to the accumulation of flour in the face.

3. The pressure relief ribs are arranged in a plurality of strips, preferably two, and one of them is disposed at the end of the thread. In this way, a pressure zone is formed between the two pressure relief ribs to prevent the back end material from entering the area, and the material of the front end of the screw can be further entered into the area to reduce the pressure between the screw and the end cover. The safety of the pasta machine is effectively ensured.

4. The safety protection structure is provided as a notch, and when the front end pressure of the screw is abnormal, the pressing front end material is discharged from the notch to the rear end, thereby reducing the pressure at the front end. The notch center line is disposed at an angle with the center line of the screw. When the screw is normally pressed, the notch does not have too much influence on the extruded surface; and when the noodle machine needs to be arranged to the rear end When the pressure is released, the material can be guaranteed to move from the notch to the back end to the maximum extent, thereby effectively releasing the pressure and achieving a safe pressure range, thereby ensuring the safety of the pasta machine.

5. The safety protection structure is a screw body with a large diameter at the front end and a small diameter at the rear end, and the pitch of the thread is gradually reduced from the rear end to the front end, and the space between the rear end of the screw and the extrusion cylinder is relatively large at the front end, the front end The pressure changes rapidly. When the current end pressure is abnormal, the material at the back end can no longer be pushed to the front end, thus effectively ensuring that the pasta machine is always processed under safe conditions. Moreover, the screw is disposed such that the front end diameter is larger than the rear end diameter, and the thread gradually decreases from the rear end to the front end and the height gradually decreases, so that the front end of the screw enters the surface when the amount of the surface is large, thereby being squeezed After a sufficient squeezing in the pressure chamber, the surface at the front end of the die is continuous, which ensures uniform surface. Setting the rear end of the screw to a smaller diameter and setting a larger pitch ensures that more dough can enter the pitch of the screw, and the dough can be fully mixed and squeezed by the extrusion of the screw, and formed. The connected noodle pieces are extruded from the exiting die, so that the noodles processed are good in continuity, and the toughness and the gluten of the noodles are improved, thereby improving the satisfaction of the use of the noodle machine.

6. A primary thread and a secondary thread are provided, and the secondary thread is located within a pitch of the primary thread. The main thread advances the dough forward at the rear end to process the feed; the main thread and the auxiliary thread cooperate at the front end, and the noodle is mixed and squeezed, the squeezing effect is good and the processing is fast, and the feeding is improved. The processing efficiency of the pasta machine.

7. The screw is provided with a pressure relief groove, and when the exit die is blocked, the pressure relief groove can further discharge the material of the extrusion nozzle and the screw front end to the rear end, and the extrusion nozzle is not in the extrusion cylinder And the front end of the screw is stacked to effectively reduce the extrusion tube and screw Pressure on the front end of the rod to prevent damage to the pasta machine.

8.

Embodiment 1

As a first embodiment of the operation-safe pasta machine of the present disclosure, as shown in FIGS. 1 to 4, the screw 7 further includes a safety protection structure including a front end of the screw 7 The pressure relief rib includes a first pressure relief rib 91 and a second pressure relief rib 92, and the main thread 73 disposed on the screw 7 is a single thread.

The screw 7 includes a screw body 700 and a baffle 71. The screw body 700 has a cylindrical shape. The baffle 71 divides the screw body 700 into a transmission portion 701 and a pressing portion 702. The transmission portion 701 is provided. There is a polygonal transmission shaft 72 through which the polygonal shaft 72 is coupled to the stirring rod. The surface of the extruded surface portion 702 is provided with a main thread 73. The front and rear heights of the main thread 73 are the same, and the pitch of the main thread 73 is gradually reduced from the rear end to the front end. The main thread 73 and the baffle 71 are A notch 76 is provided between the main thread 73 and the baffle 71, and the front end of the transmission portion 701 is further provided with a rotating protrusion 77.

As shown in FIGS. 3 and 4, the first pressure relief rib 91 is disposed at an end of the main thread 73, within a pitch formed by the main thread 73, and the end of the main thread 73 is rearward. Extending and connecting with the adjacent main thread 73, the end outlet of the main thread 73 is closed. The second pressure relief rib 92 is in the same plane as the first pressure relief rib 91, and is different from the first pressure relief rib 91 by 1.5 pitches, so that the second pressure relief rib 92 and the first pressure relief rib 91 are respectively located at two sides of the screw 7. The first pressure relief rib 91 has the same shape as the second pressure relief rib 92, The first pressure relief rib 91 and the second pressure relief rib 92 are both disposed along the axial direction of the screw 7.

As shown in FIG. 5, the second pressure relief rib 92 is the same height as the main thread 73, so that the second pressure relief rib 92 completely blocks the main thread 73. The top surface of the second pressure relief rib 92 has a width D. Of course, the first pressure relief rib 91 has the same shape as the second pressure relief rib 92, and has the same top surface width D. , 2mm D 6mm. For example, the width D may be: 2 mm, 2. 2 mm, 2. 5 mm, 2. 8 mm, 3 mm, 3. 3 mm, 3. 5 mm, 3. 8 mm, 4 mm, 4. 3 mm, 4. 5 mm, 4. 7 mm, 5mm, 5. 2mm, 5. 5mm, 5. 8mm, 6mm. The advantage of this arrangement is that if the first pressure relief rib and the second pressure relief rib width are set too small, the function of the barrier material is not well played, and the material can still freely be discharged by the first vent. The pressure retaining rib and the gap between the second pressure releasing rib and the pressing surface cylinder enter the front end of the screw, and the function of pressure relief in the present disclosure cannot be achieved; if the first pressure releasing rib and the second pressure releasing rib width are set If it is too large, during the normal processing of the pasta machine, the first pressure relief rib and the second pressure relief rib will affect the feeding of the screw, affecting the normal feeding, and thus affecting the processing efficiency of the pasta machine.

As shown in FIG. 5, the second pressure relief rib 92 has a pushing surface 921 and a blocking surface 922, and the inclined surface of the pushing surface 921 is α, 15 ° α 30 °; the inclination of the blocking surface 922 The angle is β, 0 ° β 15 ° and α > β. The α is optional: 15 °, 17 °, 19 °, 20 °, 22 °, 25 °, 27 °, 30 °, etc.; the β is optional: 0 ° , 2 ° , 4 ° , 5 ° , 7 ° , 9 ° , 10 ° , 13 ° , 15 ° , etc. The angle of inclination refers to: as shown in FIG. 5, in the transverse section of the screw 7, the center of the screw 7 is 0, and the center of the top surface of the second pressure relief rib 92 is Β, The line connecting the pushing surface 921 and the 0 即 constitutes the inclination angle of the pushing surface 921. Similarly, the line connecting the blocking surface 922 and the 0 即 constitutes the inclination angle of the blocking surface. The advantage of such setting is that: the pushing surface 921 is set to a specific angle, if the angle setting is too small, it is not conducive to the normal feeding of the screw, affecting the processing efficiency of the pasta machine; if the angle setting is too large, it is venting During the pressing process, the material will still enter the front end of the screw from the top of the first pressure relief rib and the second pressure relief rib, which does not function well. The blocking surface 922 is disposed at a small angle with the pushing surface 921. When the pasta machine is unable to discharge normally, the pressure before and after the first pressure releasing rib and the second pressure releasing rib can be raised to prevent the material from being blocked. The first pressure relief rib and the second pressure relief rib enter the front end of the screw to form a protection at the front end of the screw, thereby effectively functioning as a safety. Of course, it can be understood that the first pressure relief rib 91 also has a pushing surface and a blocking surface, and the first pressure releasing rib and the pushing surface and the blocking surface of the second pressure releasing rib can be set to be the same. Different inclination angles may be set for the inclination angle, but the inclination angles of the first pressure relief rib and the pushing surface and the blocking surface of the second pressure relief rib are the same.

The stirring rod and the screw 7 rotate at a speed of 5 (T70 rpm), and the stirring rod and the screw 7 rotate at a speed of 4 (T65 rpm) and are opposite to the stirring phase. The rotational speed selectable values include: 40 rpm, 42 rpm, 45 rpm, 48 rpm, 50 rpm, 53 rpm, 55 rpm, 58 rpm, 60 rpm, 62 rpm, 65 rpm, 67 rpm, 70 rpm, etc. The noodle machine rotates at a slightly higher rotational speed than when it exits. The utility model has the following advantages: the stirring rod only mixes and stirs flour and water during stirring, the power is small, and a large rotating speed can be set to improve the processing efficiency; when the surface is out, the screw and the feeding cylinder and the die are pressed. With the cooperation, the power is large, and the smaller speed is set to provide higher torque. If the speed setting is too small, the machining efficiency is poor. If the speed is set too large, the dry flour will be lifted during the stirring phase and the stirring will be affected. Effect, and affect the user; at the exit stage, the screw and the advance The friction between the barrel and the die increases, and the temperature rises, causing the noodles to mature, affecting the normal processing and taste of the noodles. At the same time, if the rotational speed is too large when the surface is out, the first pressure relief rib and the second pressure relief rib have more blocking materials and cannot achieve uniform feeding, which affects the normal processing of the pasta machine. When the noodle machine is stirred, the steering is opposite to the turning when the surface is turned out, so that the noodle machine can directly realize the function of the surface after the stirring is completed, so that the noodle machine can realize automatic processing without manual operation. Easy to use.

The advantage of the arrangement is that: during the noodle machine, the stirring rod with the animal material enters the extrusion nozzle from the inlet port, and the screw pushes the material to move from the rear end to the front end. And extruded by the exit die. During the processing, if the exiting die is blocked, the material continues to accumulate at the front end of the extrusion nozzle and the screw. At this time, the first pressure relief rib and the second pressure relief rib form a pressure difference before and after, a pressure region is formed in the pitch between the first pressure relief rib and the second pressure relief rib, and the pressure prevents the material from passing over the first pressure relief rib and the second pressure relief rib, thereby causing the extrusion The pressure at the front end of the dough tube and the screw is stable and will not increase continuously, effectively protecting the extrusion tube, the exit die and the end cover to prevent damage of the extrusion component.

Embodiment 2

As a second embodiment of the operation-safe pasta machine of the present disclosure, as shown in Fig. 6, the difference from the first embodiment is that the safety protection structure is a notch provided at the screw front end thread.

As shown in FIGS. 6 and 7, the safety protection structure includes a first notch 93 and a second notch 94 disposed on the main thread 73. The first notch 93 is disposed at the end of the main thread 73. The first notch 93 and the second notch 94 are disposed on the same side of the screw 7 and have a pitch difference between the front and the rear. The first notch 93 and the second notch 94 cut the main thread 73 and connect the front and rear pitches of the main thread 73.

As shown in FIG. 7, the first notch 93 and the second notch 94 have the same shape. The angle between the center line of the first notch 93 and the axis of the screw 7 is δ, 45 ° δ 70 °. The center line of the first notch 93 is biased to the opposite side of the main thread 73, that is, as shown in FIG. 7, the direction of rotation of the main thread 73 is left-handed, and the center line of the first notch 93 is biased toward the center line. The axial direction of the screw 7 is on the right side. Correspondingly, if the thread is right-handed, then The center line of the first notch is biased to the left of the axial line of the screw. The included angle δ can be selected from: 45 °, 48 °, 50 °, 52 °, 55 °, 57 °, 60 °, 63 °, 65 °, 68 °, 70 °, and the like.

With the cooperation, the power is large, and the smaller speed is set to provide higher torque. If the speed setting is too small, the machining efficiency is poor. If the speed is set too large, the dry flour will be lifted during the stirring phase and the stirring will be affected. The effect is affected by the user; during the exiting stage, the friction between the screw and the feeding cylinder and the die increases, and the temperature rises, causing the noodles to mature. The normal processing and taste of the noodles. At the same time, if the rotation speed is too large when the surface is out, some materials will be discharged backward from the first notch and the second notch when the surface is normally discharged, which will also affect the normal processing of the noodle machine, resulting in Processing efficiency is reduced.

The safety protection structure works in the following manner: during the noodle machine, the stirring rod with animal material enters the extrusion nozzle from the inlet port, and the screw pushes the material from the rear end The front end of the barrel moves and is extruded from the exit die. During normal processing, the material pressure difference between the front and rear ends of the screw is not large, and the material moves along the pitch of the thread and is finally extruded. When the pasta machine is working abnormally, that is, when the exiting die can not come out normally, at this time, the front end pressure of the pressing face cylinder and the screw increases, and the back end pressure does not change, the front end material is under the pressure The notch moves toward the rear end of the screw and prevents the material from moving to the front end, thereby ensuring that the pressure at the front end is no longer increased and the pasta machine is prevented from being damaged.

It can be understood that the safety protection structure only sets the first gap. It can be understood that the stirring rod is integrated with the screw, and a baffle is arranged between the stirring rod and the screw.

It can be understood that the screw body of the screw gradually becomes larger in diameter from the rear end to the front end, and the thread gradually becomes lower from the rear end to the front end.

As a third embodiment of the operation-safe pasta machine of the present disclosure, as shown in FIGS. 8-13, the screw 7 is advanced. The step includes a safety protection structure, which is a screw body 700 having a large front end diameter and a small rear end diameter. The surface of the screw body 700 is provided with a thread, and the pitch of the thread on the surface of the screw body 700 gradually changes from the rear end to the front end. small.

As shown in FIGS. 9, 10 and 11, the thread includes a main thread 73, a first auxiliary thread 74, and a second auxiliary thread 75. The main thread 73 is disposed on the pressing surface portion 702, and the main thread 73 is A gap 76 is formed between the baffles 71 to disconnect the main thread 73 from the baffle 71. The first auxiliary thread 74 and the second auxiliary thread 75 are disposed within the pitch of the main thread 73. The starting end of the first auxiliary thread 74 is provided with a first auxiliary thread grading starting section 741, and the starting end of the second auxiliary thread 75 is provided with a second auxiliary thread grading starting section 751. The first auxiliary thread grading starting section 741 and the second auxiliary thread grading starting section 751 mean that the first auxiliary thread 74 and the second auxiliary thread 75 are set from the starting point to the setting on the screw body 700. The height is a gradual change section, so that the first auxiliary thread 74 and the second auxiliary screw 75 are prevented from being directly disposed in the initial stage. Specifically, a starting end of the first auxiliary thread 74 is located in front of the starting end of the main thread 73, and a starting end of the first auxiliary thread progressive starting section 741 is located at a front side of the front opening 41 Between the front end of the screw 7. The starting end of the second auxiliary thread grading starting section 751 is located in front of the starting end of the first auxiliary thread grading starting section 741, that is, the second auxiliary thread grading starting section 751 is opposite to the The starting end of the first gradual initiating section 741 is closer to the front end of the screw 7. The second auxiliary threads 75 are disposed in two, evenly distributed within the pitch of the main thread 73 and the first auxiliary thread 74. The main thread 73, the first auxiliary thread 74 and the second auxiliary thread 75 terminate at the front end of the screw 7, and respectively form a step 78, whereby the step 78 is plural and along the thread end And set.

The conveying section 703 refers to the baffle 71 and the starting end of the first auxiliary thread grading starting section 741; the mixing section 704 refers to the first auxiliary thread grading starting section 741 The beginning end is between the start end of the second auxiliary thread gradual start section 751; the squeezing section 705 is between the start end of the second auxiliary thread fading start section 751 and the trailing end of the thread The extruded section 706 refers to the section of the step 78.

Preferably, the diameter of the screw body 700 located in the conveying section 703 is constant, and the diameter of the screw body 700 located in the mixing section 704 and the squeezing section 705 is gradually increased from the rear end to the front end to make the screw body of the section It has a conical shape. The main thread 73 gradually becomes smaller from the rear end to the front end and the height gradually decreases. The advantage of such an arrangement is that: during the operation of the pasta machine, the dough enters the extrusion cylinder 4 from the inlet opening 41. At this time, the dough is fluffy, and the inside of the dough is large and cannot be used for extrusion molding. When the main thread 73 is set to push the dough forward, and the main thread has a high height and a large pitch, can accommodate more dough and accelerate the advancement of the screw; in the mixing section, the diameter of the screw body becomes smaller, and the number is increased. a auxiliary thread, the space between the screw and the extrusion cylinder is reduced, the dough is squeezed and mixed in the mixing section, and the gap in the dough is compressed to form a continuous dough piece; in the squeezing section, The gap and the space between the screw and the extrusion cylinder are further reduced, and at the same time, the second auxiliary thread is added, and the main thread, the first auxiliary thread and the second auxiliary thread are jointly arranged, so that the adjacent thread pitch becomes smaller, and more The threads work together to cause the dough piece to be squeezed and squeezed multiple times in a short distance to improve the toughness of the dough piece, thereby increasing the processing of the noodle strip; in the extruded section, the step 78 pushes the dough piece It moves forward quickly and is discharged by the molding hole 61 to complete the processing.

As shown in FIGS. 9, 12 and 13, the screw 7 further includes a pressure relief groove 730 provided in the main thread 73. The vent The pressure groove 730 is located between the front side of the face opening 41 and the end of the first auxiliary thread grading start section 741. The pressure relief groove 730 is disposed along a radial direction of the screw 7 and surrounds the center of the screw 7, and the pressure relief groove 730 is for cutting the main thread 73 and conducting the front thread pitch of the main thread 73. The gap. The advantage of the arrangement is that: the pressure relief groove is disposed on the front side of the inlet port, and does not affect the pushing of the main thread; the pressure relief groove is disposed on the first auxiliary thread to gradually disappear On the back side of the end of the beginning, when pressure relief is required, the dough can be quickly discharged from the pressure relief groove to the rear end of the screw and not pushed back into the front end of the screw by the first auxiliary thread. This is because the material is discharged from the pressure relief groove. It does not fall into the pushing space of the first auxiliary thread. The gradual starting section of the first auxiliary thread can only partially push the material, and most of the dough is discharged to the rear end of the screw to realize the pressure relief function.

As shown in FIGS. 12 and 13, the pressure relief groove 730 has a "V" shape in cross section, and the bottom width of the pressure relief groove 730 is L, 3 mm ^ L ^ 6 mm (understandably, the pressure relief The groove 730 has a "V" shape in cross section, and is not limited to the bottom portion of the pressure relief groove having a sharp angle, and is mainly used to explain that the two side walls of the pressure relief groove are inclined, so The pressure relief groove may also have a bottom width when it is in a "V" shape.

The advantages of this arrangement are as follows: If the pressure relief groove is set too small, the pressure relief function cannot be well performed. When the pressure relief is required, the function of the pressure relief groove is lost because the material cannot be discharged from the pressure relief groove in time. If the pressure relief groove is set too large, during the normal processing of the pasta machine, some of the dough is discharged from the pressure relief groove to the rear end of the screw, which affects the processing efficiency of the pasta machine.

The height of the step 78 in the axial direction of the screw 8 is H, lmm H 20 mm. For example, the height H is optional: 1 let, 2 let, 3 let, 5 let, 7 let, 9 let, 10 let, 12 let, 15 let, 17 let, 20 let, etc. The advantage of this arrangement is that the step 78 is mainly used for extruding the surface. If the step height is too small, the exit speed is slow, so that the processing efficiency of the pasta machine is deteriorated; if the step height is too large, the surface is out. When a large torque is required, the processing power of the noodle machine is increased. At the same time, if the height of the step is too large, the surface of the step will accommodate more noodles, and the toughness and the gluten of the noodle block will be reduced. Affect the taste of processed noodles. The step 78 is formed by the main thread 73, the first auxiliary thread 74 and the second auxiliary thread 75 at the end of the screw, so that the step 78 has a plurality of portions, and is evenly arranged along the end of the screw When the step 78 is out of the surface, the force is uniform, the surface is even, the noodles are uniform, and the mouthfeel is good.

The advantage of such an arrangement is that the screw body is arranged to gradually increase in diameter from the rear end to the front end, and the thread gradually decreases from the rear end to the front end and the height gradually decreases, so that the screw is realized according to different functional areas. Different processing requirements can fully improve the processing efficiency of the screw and improve the processing effect of the pasta machine. The screw is provided with a main thread and a auxiliary thread, and can be quickly fed by the main thread when pushing the material, and when mixing and squeezing, the plurality of threads can fully mix the dough and fully squeeze the dough piece to enhance the noodle stripiness. Make the noodles taste better. Providing the pressure relief groove, when the noodle machine is abnormally processed, the screw and the front end material of the extrusion nozzle can be discharged to the rear end in time, and the pressure inside the screw and the extrusion nozzle is reduced, and the screw or the extrusion is prevented. The tube is damaged.

It can be understood that the diameter of the front end of the screw body is larger than the diameter of the rear end. As in the above embodiment, the rear end has a section of a cylinder, and the front end is a cone; or a cone whose diameter is gradually increased from the rear end to the front end; or The screw body The diameter gradually increases from the rear end to the front end but varies nonlinearly.
