Description

Technical Field

[0001] The invention belongs to the technical field of pressure regulation, and in particular relates to a pressure regulating device for a high-precision noodle rolling machine. Background Art

[0002] The pressure regulator of a high-precision noodle rolling mill is typically used to precisely control the pressure during the rolling process to ensure the finished product has precise dimensions, finish, and surface quality. This is typically done mechanically, by rotating a screw regulator or other mechanical device to adjust the gap between the rollers and, in turn, the pressure applied to the material.

[0003] The existing technology requires continuous adjustment of the distance between the two rollers during rolling to adjust the pressure on the opposite sides of the device. During this process, since the pressure of the rollers is adjusted by twisting the screw, it may be impossible to maintain a constant pressure, resulting in pressure fluctuations during the rolling process and affecting product quality.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention places the dough on top of the conveying member by arranging the adjustment component and the positioning component, and performs the conveying work on the surface. At the same time, the motor is started to rotate the first and second rolling rollers. During the rotation of the first and second rolling rollers, the dough is rolled on the surface. When the pressure needs to be adjusted, the staff twists the adjustment screw frame, and the adjustment screw frame drives the connecting frame to move vertically upward along the top thread of the working shell. The connecting frame drives the second cross bar and the second rolling roller to move upward, thereby adjusting the pressure. When the connecting frame stops rising, it is elastically squeezed by the extrusion spring, and the extrusion spring drives the piston plate and the positioning cone rod to move into the positioning hole of the connecting frame, thereby locking the connecting frame, preventing the connecting frame from slightly moving up and down during the operation of the device, thereby ensuring that the pressure adjustment will not be disturbed by vibration or error, and ensuring stability. When the piston plate moves, the two connecting frame plates will approach each other, and the connecting frame plates drive the elastic suction cups to move, thereby adsorbing the side walls of the connecting frame. This adsorption effect can provide additional stability, making the connecting frame more firm during operation, preventing unnecessary displacement or vibration, and improving the stability after pressure adjustment.

[0017] The present invention cooperates with adjustment components, positioning components, and auxiliary components. When the connecting frame moves upward and squeezes the positioning cone rod, the positioning cone rod drives the piston plate to move toward the squeezing spring. The piston plate moves along the interior of the square shell, allowing the edible oil inside the square shell to enter the interior of the discharger. The edible oil is sprayed toward the outer wall of the first rolling roller through the discharger, lubricating the outer wall of the first rolling roller and reducing direct frictional contact. This prevents the roller from adhering to the surface due to overly precise pressure, reduces physical contact caused by excessive pressure, and prevents excessive pressure from being generated between the first and second rolling rollers, causing the surface to adhere to the outer surface of the first rolling roller. This reduces the adhesion problem caused by excessive pressure and maintains smooth conveying of the fabric. When the piston plate moves, it drives the rotating bar, which in turn drives the block and vertical rod upward along the inner wall of the square shell. The vertical rod drives the L-shaped frame and elastic frame plate upward, and the elastic frame plate drives the sponge bar upward, thereby coating the outer wall of the first rolling roller with cooking oil, allowing the cooking oil to adhere evenly to the outer wall of the first rolling roller. This coating prevents the fabric from sticking to the first rolling roller, avoiding surface damage or uneven quality problems caused by excessive friction. It also helps maintain stable operation of the device and reduces equipment failures and maintenance requirements.

[0018] The present invention cooperates with an adjustment component, a positioning component, an auxiliary component, and a reflux component. When the sponge bar rises vertically, the edible oil adsorbed inside the sponge bar falls after being squeezed by the first rolling roller, and the edible oil falls into the interior of the receiving shell. This process effectively collects the excess edible oil on the outer wall of the first rolling roller, avoiding waste. At the same time, when the piston plate moves along the inner wall of the square shell toward the connecting frame, suction is generated. This suction draws the edible oil collected in the receiving shell through the bend and guides it into the interior of the square shell, thereby realizing the recovery and recycling of the edible oil. This design not only improves the efficiency of resource utilization, but also effectively reduces the waste of edible oil, further ensuring the stability and environmental protection of the production process.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

[0034] The pressure regulating mechanism 5 includes a motor 51 fixedly connected to the bottom of the inner cavity of the working shell 1, and the output end of the motor 51 is fixedly connected to a rotating shaft 52. The outer wall of one end of the rotating shaft 52 is fixedly connected to a first bevel gear 53. The outer wall of one end of the rotating shaft 52 close to the first bevel gear 53 is fixedly connected to a second bevel gear 54. The outer wall of the first bevel gear 53 is provided with an adjusting component 55 for adjusting the pressure.

[0035] The adjustment assembly 55 includes a third bevel gear 551 meshedly connected to one side of the outer wall of the first bevel gear 53, and a first cross bar 552 is fixedly connected to one side of the third bevel gear 551. The middle end outer wall of the first cross bar 552 is fixedly connected to the first rolling roller 553, and the first rolling roller 553 is arranged on the outside of the working shell 1. The outer wall of the second bevel gear 54 is meshedly connected to the fourth bevel gear 554.

[0036] One side of the fourth bevel gear 554 is fixedly connected to a second cross bar 555, and the outer walls of both ends of the second cross bar 555 are slidably connected to the inner wall of the strip hole 4, and the outer wall of the middle end of the second cross bar 555 is fixedly connected to the second rolling roller 556, and the outer walls of both ends of the second cross bar 555 away from the second rolling roller 556 are rotatably connected to a connecting frame 557, and a plurality of positioning holes 558 are provided on one side of the outer wall of the connecting frame 557, and the top of the connecting frame 557 is rotatably connected to an adjusting screw frame 559, and the outer wall of one end of the adjusting screw frame 559 is threadedly connected to the top of the working shell 1.

[0037] A positioning assembly 56 is provided on the inner wall of the working shell 1. The positioning assembly 56 includes a square shell 561 that penetrates and is fixedly connected to one side of the inner wall of the working shell 1. The inner wall of the square shell 561 is slidably connected to a piston plate 562. One side of the piston plate 562 is fixedly connected to multiple positioning cone rods 563. One end of the positioning cone rod 563 contacts the inner wall of the positioning hole 558.

[0038] The above solution is adopted: the positioning cone rod 563 moves into the positioning hole 558 at the connecting frame 557, thereby positioning the connecting frame 557 to prevent the connecting frame 557 from moving slightly up and down during the operation of the device, thereby ensuring that the pressure will not be disturbed by vibration or error after adjustment, and ensuring stability.

[0039] One end of the piston plate 562 away from the positioning cone rod 563 is fixedly connected to two extrusion springs 564, one end of the extrusion spring 564 is fixedly connected to the inner wall of the square shell 561, and both ends of the side of the piston plate 562 close to the positioning cone rod 563 are rotatably connected to a rotating plate 565. Sliding holes 566 are respectively provided at both ends of one side of the outer wall of the square shell 561, and the end of the rotating plate 565 away from the piston plate 562 is rotatably connected to a slider 567.

[0040] The outer wall of the slider 567 is slidably connected to the inner wall of the sliding hole 566, and the end of the slider 567 away from the rotating plate 565 is fixedly connected to the connecting frame plate 568. A plurality of elastic suction cups 569 are passed through and slidably connected to one side of the outer wall of the connecting frame plate 568, and one end of the elastic suction cup 569 contacts the side wall of the connecting frame 557.

[0041] With the above solution, the elastic suction cup 569 can generate an adsorption force to adsorb the outer wall of the connecting frame 557, thereby reducing the phenomenon of slight upward and downward movement of the connecting frame 557.

[0042] like Figures 1 to 11 As shown, the outer wall of the square shell 561 is provided with an auxiliary component 57, and the auxiliary component 57 includes a discharger 571 connected to one side of the outer wall of the square shell 561. The outer wall of one end of the discharger 571 is connected to a first one-way valve 572, and the side of the piston plate 562 close to the extrusion spring 564 is rotatably connected to a rotating bar 573.

[0043] With the above solution, the first one-way valve 572 can discharge the cooking oil inside the square shell 561 to the outside, and prevent the outside air from entering the inside of the square shell 561 through the discharger 571 .

[0044] The end of the rotating bar 573 away from the piston plate 562 is rotatably connected to the block 574, the bottom of the block 574 is fixedly connected to the vertical rod 575, the bottom of the vertical rod 575 is fixedly connected to the L-shaped frame 576, and the side wall of the end of the L-shaped frame 576 away from the vertical rod 575 passes through and is slidably connected to the elastic frame plate 577.

[0045] A sponge strip 578 is fixedly connected to the side wall of one end of the elastic frame plate 577, and one side of the sponge strip 578 is in contact with the outer wall of the first rolling roller 553. A sealing ring 579 is fixedly connected to the bottom of the square shell 561, and the inner wall of the sealing ring 579 is sleeved on the outer wall of one end of the vertical rod 575.

[0046] With the above solution, the sealing ring 579 can seal the sliding hole between the square shell 561 and the vertical rod 575 , thereby improving the sealing effect inside the square shell 561 .

[0047] The inner cavity of the working shell 1 is provided with a reflux component 58, which includes a fixed rod 581 fixedly connected to the center of the bottom of the inner cavity of the working shell 1, and the top of the fixed rod 581 is fixedly connected to the receiving shell 582. The bottom side of the receiving shell 582 is connected to a curved pipe 583, and the end of the curved pipe 583 away from the receiving shell 582 is connected to the bottom of the square shell 561, and the outer wall of one end of the curved pipe 583 is connected to a second one-way valve 584.

[0048] With the above solution, the second one-way valve 584 allows the cooking oil in the receiving shell 582 to enter the interior of the square shell 561 through the bend 583 , and prevents the cooking oil in the square shell 561 from entering the interior of the receiving shell 582 through the bend 583 .

[0049] The working principle and use process of the present invention:

[0050] The noodles are placed on the top of the conveying member 3 and the opposite side is conveyed. At the same time, the motor 51 is started, the working shell 1 drives the rotating shaft 52 to rotate, and the rotating shaft 52 drives the first bevel gear 53 and the second bevel gear 54 to rotate. The first bevel gear 53 drives the third bevel gear 551 to rotate, and the third bevel gear 551 drives the first cross bar 552 and the first noodle rolling roller 553 to rotate. The second bevel gear 54 drives the fourth bevel gear 554 to rotate. The fourth bevel gear 554 drives the second cross bar 555 and the second noodle rolling roller 556 to rotate. During the rotation of the first noodle rolling roller 553 and the second noodle rolling roller 556, the noodle rolling work is performed on the opposite side. When the pressure needs to be adjusted, the staff twists the adjusting screw rack 559, and the adjusting screw rack 559 drives the connecting rack 557 to move vertically upward along the top thread of the working shell 1. The connecting rack 557 drives the second cross bar 555 and the second noodle rolling roller 556 to move upward, thereby adjusting the pressure. When the connecting frame 557 stops rising, it is elastically squeezed by the extrusion spring 564, which drives the piston plate 562 and the locking cone rod 563 to move into the locking hole 558 of the connecting frame 557, thereby locking the connecting frame 557 in place and preventing the connecting frame 557 from moving slightly up and down during operation. This ensures that the pressure adjustment is not disturbed by vibration or error, ensuring stability. When the piston plate 562 moves, the piston plate 562 drives the rotating plate 565 to move, and the rotating plate 565 drives the slider 567 to slide along the inner wall of the sliding hole 566. The slider 567 drives the connecting frame plate 568 to move, and the two connecting frame plates 568 approach each other. The connecting frame plate 568 drives the elastic suction cup 569 to move, thereby adsorbing the side wall of the connecting frame 557. This adsorption effect provides additional stability, making the connecting frame 557 more secure during operation, preventing unnecessary displacement or vibration, and improving the stability after pressure adjustment.

[0051] As the connecting frame 557 moves upward, squeezing the locking cone rod 563, the locking cone rod 563 drives the piston plate 562 toward the squeezing spring 564. The piston plate 562 moves along the interior of the square shell 561, allowing the cooking oil inside the square shell 561 to enter the interior of the discharger 571. The cooking oil is sprayed through the discharger 571 toward the outer wall of the first noodle roller 553, lubricating the outer wall of the first noodle roller 553 and reducing direct frictional contact. This can reduce physical contact caused by excessive pressure and prevent excessive pressure from being generated between the first noodle roller 553 and the second noodle roller 556, which could cause the dough to adhere to the outer surface of the first noodle roller 553. This reduces the problem of adhesion caused by excessive pressure and maintains smooth conveyance of the fabric. When the piston plate 562 moves, it drives the rotating bar 573 to move. The rotating bar 573 drives the block 574 and the vertical rod 575 upward along the inner wall of the square housing 561. The vertical rod 575 drives the L-shaped frame 576 and the elastic frame plate 577 upward. The elastic frame plate 577 drives the sponge bar 578 upward, thereby coating the outer wall of the first noodle rolling roller 553 with cooking oil, allowing the cooking oil to adhere evenly to the outer wall of the first noodle rolling roller 553. This cooking oil coating prevents the fabric from sticking to the first noodle rolling roller 553, avoiding surface damage or uneven quality problems caused by excessive friction. It also helps maintain stable operation of the device and reduces equipment failures and maintenance requirements.

[0052] When the sponge strip 578 rises vertically, the edible oil absorbed inside the sponge strip 578 falls off after being squeezed by the first rolling roller 553, and the edible oil will fall into the inside of the receiving shell 582. This process effectively collects the excess edible oil on the outer wall of the first rolling roller 553, avoiding waste. At the same time, when the piston plate 562 moves along the inner wall of the square shell 561 toward the connecting frame 557, suction is generated. This suction sucks the edible oil collected in the receiving shell 582 through the bend 583 and guides it into the inside of the square shell 561, thereby realizing the recovery and recycling of the edible oil. This design not only improves the efficiency of resource utilization, but also effectively reduces the waste of edible oil, further ensuring the stability and environmental protection of the production process.
