As a specific embodiment of the pasta machine with stable extrusion of the present invention, as shown in fig. 1 to 10, the pasta machine comprises a stationary housing 55 and a pressure roller. The dough pressing rollers are arranged in pairs and extend along the axial direction to form an extrusion gap between a group of dough pressing rollers, and the dough maker comprises four groups of continuously arranged dough pressing rollers, namely a first dough pressing roller 31, a second dough pressing roller 32, a third dough pressing roller 33 and a fourth dough pressing roller 34 from front to back. An extrusion gap is formed between each group of dough pressing rollers, and the extrusion gap is the distance between the outer surfaces of the same group of dough pressing rollers, not the distance of the circle center; similarly, the extrusion speed of the pressure rollers refers to the linear speed of the outer surface of the pressure rollers, but not the rotational speed of the pressure rollers, and for the same set of pressure rollers, the rotational directions are opposite and the speeds are the same. The distance between two adjacent flour pressing rollers refers to the distance between the outer surfaces of two rollers on the same side of the two adjacent flour pressing rollers. The product of the nip and the extrusion speed of the calender roll constitutes the processing amount of the calender roll, and the speed (cm/s) × the distance (cm) ═ cm seen from the cross section, that is, the area of the nip flowing through the calender roll per unit time²As a whole, i.e. the single-stage calender roll unitVolume of dough (cm) processed in time³/s)。

The dough roller comprises a roller body 311 and a roller shaft 312, wherein the roller shaft 312 is arranged at two ends of the roller body 311, preferably, the roller shaft 312 is a waist-shaped shaft. The fixed case 55 is provided with a roller shaft hole 551, and the roller shaft 312 is inserted into the roller shaft hole 551 and is rotatable in the roller shaft hole 551. Preferably, the fixing housing 55 includes fixing plates 552 arranged in parallel, the fixing plates 552 are arranged opposite to each other and form a processing chamber 553 in the middle, the two sides of the dough roller extend into the roller shaft holes of the fixing plates, and the roller body 311 is located in the processing chamber 553. Like this, fixed plate 552 is located processing chamber one side and can sets up to the surface of bright and clean, has guaranteed the holistic clean and tidy of wheaten food, does benefit to the clearance of dough, and simultaneously, the fixed plate still can carry on spacingly to the both sides of roller of pressing the face, when the roller of pressing the face is accomplishing the extrusion, and the conglobation that extends to both sides is spacing by the fixed plate, and the dough is more extends forward. The clearance between the two sides of the roller body and the fixing plate is set to be not more than 2mm, so that the fixing plate can better limit the roller body when the dough pressing roller finishes extrusion, and meanwhile, dough is not easy to enter a gap between the dough pressing roller and the fixing shell, and the reduction of the sanitation caused by the residual dough in the gap is avoided. The diameter of the roller body is set to be not more than 40mm, so that the whole volume of the wheaten food machine can be set to be small and exquisite as much as possible, and although the diameter of the roller body is small, the purpose of quickly making noodles by the wheaten food machine can be still met by setting a high rotating speed.

The wheaten food machine is provided with a driving component for enabling each level of dough pressing roller to be linked, preferably, the driving component comprises a gear component connected with different levels of dough pressing rollers respectively, and the gear component comprises a first-level gear 51, a first driving tooth 521, a first driven tooth 522, a second driving tooth 531, a second driven tooth 532, a third driving tooth 541 and a third driven tooth 542. The primary gears 51 are arranged in pairs and correspond to each stage of dough pressing roller, and the primary gears 51 have the same structure, so that the rotating speeds of the dough pressing rollers of each stage are the same, and the rotating directions are opposite. The first driving tooth 521 is provided with a transmission hole 523 and is connected with a power source through the transmission hole 523, the first driving tooth 521 drives a fourth dough pressing roller and simultaneously drives a first driven tooth 522, the first driven tooth 522 is coaxially arranged with a third dough pressing roller and a second driving tooth 531, the second driving tooth 531 further drives a second driven tooth 532, the second driven tooth 532 is coaxially arranged with the second dough pressing roller and a third driving tooth 541, the third driving tooth 541 further drives a third driven tooth 542, and the third driven tooth 542 is coaxially arranged with the first dough pressing roller. Preferably, the second driving gear 531, the second driven gear 532 and other gear sets are respectively disposed at two sides of the fixed housing 55, so that an excessive space occupied by the transmission assembly when the two gears are disposed at the same side can be avoided.

When the wheaten food machine works, the power source drives one of the first-stage dough pressing rollers to rotate through the transmission hole, drives other first-stage dough pressing rollers to synchronously rotate through the gear set, and the extrusion speed of the different first-stage dough pressing rollers is in a preset value through setting the transmission proportion of the gear set.

The process volume of back one-level pressure face roller is greater than the process volume of preceding one-level pressure face roller in the adjacent two-stage pressure face roller, thus, in the course of working, back one-level needs more dough to satisfy its process volume, but strengthen extruded dough by preceding one-level pressure face and be not enough to satisfy back one-level pressure face roller completely, back one-level pressure face roller has the trend of dragging in order to satisfy its self process volume, thus, back one-level pressure face roller is in the extruded while, can produce backward pulling force to the dough, the line direction of gluten is unanimous in this kind of pulling force and the dough, can be favorable to the line formation of noodless more, make noodless more chewy, the taste is better, satisfy the demand that personnel pursue better quality wheaten food.

The extrusion clearance of the dough pressing roller is reduced from front to back in sequence, and meanwhile, the extrusion speed of the dough pressing roller is increased from front to back in sequence. The extrusion gap of the first dough pressing roller is H1, the extrusion speed is V1, correspondingly, the extrusion gap of the second dough pressing roller is H2, and the extrusion speed is V2; the extrusion gap of the third dough pressing roller is H3, and the extrusion speed is V3; the extrusion gap of the fourth dough roller is H4, and the extrusion speed is V4. Wherein H1> H2> H3> H4, and V1< V2< V3< V4. Furthermore, the extrusion gap and the extrusion speed of the two adjacent stages of the dough rollers have a proportional relation, namely V2/V1 is k multiplied by H1/H2, and 1< k is less than or equal to 1.5. When k is 1, the extrusion gap and the extrusion speed of the two adjacent dough pressing rollers have an inverse proportional relation, so that the flow rate (namely the volume of the dough sheet flowing through the dough pressing rollers in unit time) of the two adjacent dough pressing rollers is the same, the dough sheet extruded by the previous dough pressing roller is ensured, and in the continuous thinning process of the next dough pressing roller, the dough sheet can be normally extruded at a higher speed, and the situation that the next dough pressing roller cannot be completely extruded and stacked at the next dough pressing roller after the previous dough pressing roller finishes is avoided. Further, set up k >1, can guarantee that the last one-level last roll has faster extrusion speed, can guarantee the normal extrusion of extrusion subassembly, simultaneously, because last one-level last roll extrusion speed is very fast, when accomplishing normal extrusion, last roll still can produce certain effect of dragging to the dough sheet for the gluten of dough sheet is more smooth and easy, and the dough sheet is more bright and clean, advances the face and has guaranteed the taste of noodless. Set up k <1.5, guarantee that the effect of dragging between one-level last-flour noodle roller and the preceding one-level last-flour noodle roller can not be too big, if k sets up great, the effort of dragging of the last-level last-flour noodle roller is too big, probably causes the dough sheet to break at the extrusion in-process, influences the normal processing of extrusion subassembly on the contrary. Of course, for the dough with enough toughness, for example, common stretched noodles, the dough itself has enough toughness and needs to be repeatedly pulled, at this time, the dough pressing roller with larger pulling force is arranged, so that the requirement of pulling the dough can be met, and the noodles meeting the requirement can be processed.

The extrusion gap is set to be not more than 10mm, namely the maximum extrusion gap of each level of dough pressing roller is 10 mm. Preferably, the extrusion gap of the first-stage dough pressing roller is not more than 8mm, and can be 6mm, 7mm, 8mm and the like; the extrusion gap of the second-stage dough pressing roller is not more than 6mm, and can be 4mm, 5mm, 6mm and the like; the extrusion gap of the third-stage dough pressing roller is not more than 4mm, and can be 2mm, 3mm, 4mm and the like; the extrusion clearance of fourth level pressure face roller sets up to no longer than 2mm, and the preferred 1mm that is can guarantee like this that the final dough sheet of wheaten food machine or noodless can satisfy user's demand at thickness, guarantee better taste. Meanwhile, the compression ratio between every two stages of dough pressing rollers is reasonably set, and the next stage of dough pressing roller does not need overlarge extrusion force.

The distance between every two adjacent flour pressing rollers is H, and H is less than or equal to 30 mm. Because the pasta machine is mainly used for household use, namely a user usually uses the pasta machine in a household kitchen, the user only needs to generate a small volume to meet the requirements of pasta processing. The space between two adjacent dough pressing rollers is too large, so that the product volume is increased, namely the product occupies space, and the product is inconvenient to move and operate by a user; on the other hand, the interval is too big, and the dough sheet needs to set up transmission structure specially when transmitting between two-stage pressure face roller, needs extra power to guarantee even that the dough sheet can follow last level pressure face roller and transmit to next level pressure face roller, makes the product more complicated equally.

Because the function that the pressure face roller mainly realizes relies on extrusion clearance and extrusion speed between the same group pressure face roller, consequently, only need guarantee the extrusion clearance and the extrusion speed of pressure face roller can, the diameter of pressure face roller can set up according to the volume demand of product to, the pressure face roller of different stages can set up to same diameter size or different diameter size. Preferably, in this embodiment, the distances between the rotation centers of the four-stage dough pressing rollers are the same, and the diameters of the four-stage dough pressing rollers are sequentially increased, so that the installation distance of the four-stage dough pressing rollers and the driving device can be set to be the same. Of course, the diameter of the flour pressing roller can be completely the same, so that all the flour pressing rollers can be used commonly, and the production and the manufacture of the flour pressing rollers are convenient.

As shown in fig. 3, a connecting line between the center of the pressing gap of the first press roller 31 and the center of the pressing distance of the second press roller 32 forms an angle a with the vertical direction, where a is greater than 0 °, that is, the pressing distance of the pressing assembly is not completely set in the vertical direction, but is set obliquely to one side. Preferably, the angle a is >45 °. The extrusion assembly is obliquely arranged, so that the height in the vertical direction can be reduced, and the phenomenon that the height of a cooked wheaten food machine product is too high is avoided; simultaneously, dough sheet or noodless after the extrusion subassembly processing is accomplished are discharged from the lateral wall by the extrusion subassembly guide, and can not be located the processing subassembly below that knead dough subassembly and extrusion subassembly constitute, and the person of facilitating the use controls the dough sheet or noodless that processing was accomplished.

As shown in fig. 2 and 3, a guide plate 35 is further provided between the two adjacent stages of the dough rollers, the guide plate 35 is provided between the lower dough rollers of the two adjacent stages of the dough rollers, the guide plate 35 includes a guide portion 351 and a fixing portion 352, a guide surface 350 is formed on the upper side of the guide portion 351, and the guide surface 350 is provided along the pressing direction of the dough rollers. The guide plate 35 has a T-shaped cross section, the guide portion 351 is located at the upper portion and has a plate shape, and the fixing portion 352 is located at the opposite side of the guide surface 350 for connecting and fixing with the base. The guide plates positioned between different dough pressing rollers are set to be different in size according to the space between different dough pressing rollers. Preferably, the guide plate 35 may be slightly longer in axial length than the pressure roller, i.e., both sides of the guide plate protrude from the pressure roller. When the dough pressing roller extrudes the dough sheet, the extrusion gap is smaller than the thickness of the dough sheet, the dough sheet becomes thin, therefore, the dough sheet can deform forwards and forwards at two sides to release the volume change of the dough sheet, the dough sheet extends forwards to be expected to be thin, and the deformation towards the two sides is not expected, generally, the side surface of the dough pressing roller is attached to the fixing seat of the extrusion assembly, the dough sheet is prevented from extending towards the two sides by the fixing seat, but the extruded dough sheet has the tendency of extending towards the two sides, so that the dough sheet can generate deformation and distortion, and the introduction of the dough sheet into the next-stage dough pressing roller is not facilitated. The width of the guide plate is set to be larger than that of the dough pressing roller, so that the extension trends of dough sheets on two sides can be released during guiding, the dough sheets are more flat during transferring, and the dough sheets are favorably transferred to the lower-level dough pressing roller.

The lower dough pressing roller connecting line of two adjacent dough pressing rollers forms a pressing surface 310, the distance between the guide surface and the pressing surface is L, the radius of the smaller dough pressing roller of the adjacent dough pressing rollers is R, and 0< L < R. Like this, as shown in fig. 3, the extension line of the guide surface and the tangent line of the intersection point of the dough pressing roller form an obtuse angle, the dough sheet extruded by the first dough pressing roller is transmitted to the second dough pressing roller along the guide surface, after the dough sheet is contacted with the second dough pressing roller, the running direction of the dough sheet and the rotating direction of the dough pressing roller form a smaller included angle, the dough sheet is easily driven by the dough pressing roller and is received and extruded by the second dough pressing roller, the dough sheet is high in transmission efficiency between the two stages of dough pressing rollers, the extrusion assembly is high in running speed, and the processing efficiency and speed of the pasta machine are ensured.

The upper end of the guide portion 361 is located at the lower side of the noodle inlet 30, the lower end of the guide portion 361 inclines towards one side of the noodle pressing roller, the lower end of the guide portion 361 is further provided with a shielding portion 363, the shielding portion 363 is arranged at the lower end of the guide portion 361 and extends along the opposite side of the guide surface 360, and the shielding portion 363 is arranged in an arc shape similar to the shape of the noodle pressing roller on the opposite side of the noodle pressing roller. Preferably, the extension line of the guide surface 360 is located between the centers of the two pressure rollers of the first-stage pressure roller 31, i.e., located above the center of the lower pressure roller, so that the tangent line at the intersection point of the guide surface 360 and the pressing surface of the lower pressure roller forms an obtuse angle, and the dough sheet entering from the dough inlet 30 is guided by the guide surface 360 and rapidly enters the pressing gap of the pressure roller.

As shown in fig. 8-10, the pasta machine is further provided with a noodle cutting assembly disposed downstream of the last level of the dough rollers, so that the dough sheet extruded by the dough rollers can directly enter the noodle cutting assembly and be cut into noodles by the noodle cutting assembly. The tangent plane subassembly includes mated tangent plane roller, and single tangent plane roller is equipped with tangent plane tooth 61 and tangent plane groove 62 along the axial in proper order, and mated tangent plane groove parallel arrangement, and simultaneously, corresponding tangent plane tooth sets up with tangent plane groove is crisscross to tangent plane tooth pegs graft each other with tangent plane groove, and the tangent plane tooth of the tangent plane roller of one side inserts the tangent plane inslot of the tangent plane roller of opposite side promptly, and like this, the dough is sheared through two adjacent tangent plane teeth, accomplishes the shaping of noodless. Preferably, the tangent plane tooth and the tangent plane groove are set to be equal in width.

Further, clean tooth end sets up to the arc with tangent plane roller assorted to the clearance of cleaning the teeth and having a cut the dough roller is not more than 2mm, and like this, the clean tooth of cleaning can be pressed close to tangent plane tank bottom as far as possible, and can be clean more thoroughly.

In the above embodiments, the various proportional relationships and parameters do not limit the specific pressure roller or the two-stage specific position pressure rollers, but include the matching relationship between all the pressure rollers and the adjacent pressure rollers, and therefore, although the embodiment limits V2/V1 to k × H1/H2, the embodiment does not limit the proportional relationship between the first-stage pressure roller and the second-stage pressure roller, but means that all the adjacent two-stage pressure rollers follow such a proportional relationship.

It is understood that the dough rollers can be arranged in three groups, five groups, six groups, etc.

It will be appreciated that the calender rolls may be set to rotate at exactly the same speed, with the nip and speed being set according to proportions. Therefore, the transmission can be realized by directly arranging the same transmission gear, and the transmission is convenient.

It can be understood that the pasta machine can be finally added with a flat roller with the same extrusion gap as the previous roller and with the same or faster extrusion speed. Because the extrusion clearance between every grade of extrusion subassembly reduces in proper order, the dough sheet that extrudees has the trend of kick-backing, and the dough sheet that extrudes at last must be equal to the extrusion clearance of last one-level pressure face roller completely to, because the extrusion clearance between the pressure face rollers of each grade continues to reduce, the dough sheet that extrudes at last probably influences the outward appearance shape of final dough sheet or noodless owing to receive volume change and produce burr or deformation etc.. The dough pressing roller with the same extrusion gap is further arranged, the dough sheet can be reshaped after the last-stage dough pressing roller is extruded, the gap output of the dough sheet according to the design requirement is ensured, and meanwhile, the burr equal-pressure dough pressing sheet can be used for enabling the appearance of the final dough sheet or the noodle to be tidier and more tidy, and the satisfaction degree of a user is improved.

It will be appreciated that the drive assembly may also be provided with a universal drive such as a belt drive.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, i.e. all equivalent changes and modifications made according to the present invention are covered by the scope of the claims of the present invention, which is not illustrated herein.
