Description

Technical Field

[0001] The invention relates to the technical field of fried pasta processing, in particular to a slicer for processing fried pasta. Background Art

[0002] The processing of fried noodles usually requires three steps: kneading, resting and shaping. Shaping involves rolling, squeezing and cutting the rested dough. During the dough cutting process, the cutting blade may stick to the dough, especially when the moisture content of the dough is high or the surface of the dough is relatively moist, which will affect the subsequent cutting work. Summary of the invention

[0003] The invention aims to provide a slicer for processing fried pasta, which can prevent the cutting blade from adhering to the dough and improve the cutting work quality.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: a slicer for processing fried pasta, comprising a processing frame and a conveying frame located below the processing frame, wherein the processing frame and the conveying frame are both provided with conveyor belts, and the processing frame is provided with a dough pressing component, an oiling component, a dough cutting component and a slicer component in sequence along the conveying direction of the conveyor belt, the dough pressing component is used to roll the dough into a dough cake, the oiling component is used to oil the surface of the dough cake, the dough cutting component is used to evenly cut the dough cake into strips, and the slicer component is used to cut the strip dough cake into slices.

[0005] By adopting the above technical scheme, the kneaded dough is transported along the processing frame conveyor belt in the shape of strips. The dough pressing component first squeezes the dough into a flat dough cake to facilitate subsequent slicing of the dough. Then the oiling component oils the surface of the dough cake. The dough cake is evenly cut into long strips when passing through the cutting component. The oiling can form a thin film on the surface of the dough, reducing the friction between the dough and the blade, thereby reducing the possibility of adhesion and making the cutting smoother. The dough cake cut into long strips is cut into several pieces to achieve the shape of a finished product when passing through the slicing component, which is conducive to the subsequent frying work.

[0006] The present invention is further configured as follows: the noodle pressing assembly includes brackets fixed on both sides of the processing frame and noodle pressing rollers rotatably connected between the brackets on both sides.

[0007] By adopting the above technical solution, the dough is squeezed into a flat shape by the dough pressing roller when passing through the dough pressing roller, which is convenient for subsequent cutting and processing.

[0008] The present invention is further configured as follows: the noodle cutting assembly comprises a lifting frame arranged on the processing frame and a plurality of equidistantly arranged connecting plates sliding on the lifting frame, and a noodle cutting knife is fixed to the bottom end of the connecting plate.

[0009] By adopting the above technical solution, the dough cutter can cut the dough into long strips at equal intervals. At the same time, since there is a thin film of oil on the dough, the dough and the dough cutter will not stick to each other. The dough cutter can slide through the dough more easily without pulling the dough during cutting, thereby maintaining the integrity and uniformity of the slices.

[0010] The present invention is further configured as follows: lifting cylinders are fixed on both sides of the processing frame, and the lifting frame is fixed between the output ends of the lifting cylinders on both sides.

[0011] By adopting the above technical solution, the operation of the noodle cutting knife is controlled by controlling the lifting height of the noodle cutting knife through the lifting cylinder.

[0012] The present invention is further configured as follows: a connecting rod perpendicular to the conveying direction of the conveyor belt is fixed on the lifting frame, the connecting plate is inserted and slid on the connecting rod, the lifting frame is rotatably connected to an adjusting shaft, a plurality of limit grooves are provided on the adjusting shaft, the limit groove located in the middle is vertically arranged along the wall surface of the adjusting shaft, the other limit grooves are symmetrically distributed along the limit groove located in the middle and the ends are inclined toward the middle, a limit block sliding in the limit groove is fixed on the connecting plate, and an adjusting motor for driving the adjusting shaft to rotate is installed on the lifting frame.

[0013] By adopting the above technical solution, the adjusting motor drives the adjusting shaft to rotate, and the rotation of the adjusting shaft controls the sliding of the limit block through the limit groove, so that multiple connecting plates slide along the direction of the connecting rod to adjust the distance between the connecting plates, thereby adjusting the distance between the cutting knives, so that the cutting knives can cut dough of different widths, thereby improving production flexibility and meeting the market demand for different products.

[0014] The present invention is further configured as follows: the oiling assembly includes an oil tank fixed on the processing frame, an oil outlet arranged below the oil tank, a blocking block sliding on the oil tank and covering the oil outlet, and a sponge block fixed to the oil tank and located below the oil outlet.

[0015] By adopting the above technical solution, the oil tank is filled with edible oil, and the blocking block is used to block the oil outlet. When the blocking block rises, the oil outlet is opened, and the edible oil in the oil tank overflows from the oil outlet onto the sponge block. The sponge block evenly spreads the oil on the dough to avoid uneven or excessive oil distribution.

[0016] The present invention is further configured as follows: the slicing assembly includes a fixed frame fixed between the end of the processing frame and the conveying frame, two slicing rollers located above the conveying frame and rotating on the fixed frame, and slicing knives fixed to the slicing rollers and evenly arranged along the circumference of the slicing rollers, a driving motor for driving the slicing rollers to rotate is installed on the fixed frame, the slicing rollers are fixed with a rotating shaft that rotates and extends out of the fixed frame, and two ends of the rotating shafts are fixed with gears that mesh with each other.

[0017] By adopting the above technical scheme, when the conveyor belt continues to transport the noodles cut into strips forward, the noodles hang from the conveyor belt and fall between the slicing rollers on both sides. The driving motor drives the slicing roller on one side to rotate, and drives the slicing roller on the other side to rotate in the opposite direction through the engagement of two gears. Then, the slicing rollers on both sides rotate in the opposite direction and the slicing knife cuts the noodles evenly into slices to achieve the finished product shape. The sliced ​​noodles fall onto the conveyor belt of the conveyor rack and continue to be transported forward, which is conducive to the subsequent frying work.

[0018] The present invention is further configured as follows: the processing frame is hinged with an inclined movable plate located below the slicing roller, the fixed frame is rotatably connected with a movable shaft, a first belt is sleeved between one end of the movable shaft and the end of the rotating shaft, and the other end of the movable shaft is located below the movable plate and is fixed with a first cam.

[0019] By adopting the above technical solution, the sliced ​​dough falls onto the movable plate. When the slicing roller and the rotating shaft rotate, the rotating shaft drives the movable shaft to rotate synchronously through the first belt. The rotation of the movable shaft drives the movable plate to move up and down repeatedly relative to the processing frame through the first cam, so as to scatter the dough on the movable plate to avoid the dough sheets from sticking to each other. At the same time, the dough on the movable plate is shaken off onto the conveyor belt, which is convenient for subsequent processing.

[0020] The present invention is further configured as follows: the cross section of the oil outlet is configured as an inverted trapezoid, and the blocking block is configured as an inverted trapezoid block adapted to the oil outlet.

[0021] By adopting the above technical solution, when the blocking block moves upward, part of the oil outlet can be opened to control the oil flow in the oil outlet; when the blocking block falls, the oil outlet is closed.

[0022] The present invention is further configured as follows: a slot is provided at the upper end of the sponge block for the bottom end of the blocking block to extend into, sliding plates that slide out of the sponge block are fixed on both sides of the blocking block, fixed plates are fixed on both sides of the oil tank, sliding rods that are inserted and slid on the fixed plates are fixed on the sliding plates, a telescopic spring that is sleeved on the outside of the sliding rod is fixed between the sliding plate and the fixed plate, connecting shafts are rotatably connected on both sides of the processing frame, a second cam that contacts the sliding plate is fixed at one end of the connecting shaft, and a second belt is sleeved between the end of the connecting shaft away from the second cam and the end of the rotating shaft.

[0023] By adopting the above technical solution, when the rotating shaft rotates to perform slicing, the connecting shaft is driven to rotate by the second belt. The connecting shaft rotates to repeatedly lift the sliding plate and the blocking block through the cam to add oil to the sponge block. This can avoid the oil outlet being kept open during work to over-oil the sponge block and waste raw materials. It can also be started and stopped according to the working state of the rotating shaft, thereby improving the coordination and reliability between structures.

[0024] The beneficial effects of the present invention are:

[0025] 1. The kneaded dough is transported along the conveyor belt of the processing frame in the form of strips. The dough pressing component first squeezes the dough into a flat dough cake to facilitate subsequent slicing of the dough. Then the oiling component applies oil to the surface of the dough cake. When passing through the cutting component, the dough cake is evenly cut into strips. The oiling can form a thin film on the surface of the dough, reducing the friction between the dough and the blade, thereby reducing the possibility of adhesion and making cutting smoother;

[0026] 2. The adjusting motor drives the adjusting shaft to rotate. The adjusting shaft rotates to control the sliding of the limit block through the limit slot, so that multiple connecting plates slide along the direction of the connecting rod to adjust the distance between the connecting plates, thereby adjusting the distance between the cutting knives, so that the cutting knives can cut dough of different widths, improve production flexibility, and meet the market demand for different products;

[0027] 3. The oil tank is filled with edible oil, and the block is used to block the oil outlet. When the block rises, the oil outlet is opened, and the edible oil in the oil tank overflows from the oil outlet onto the sponge block. The sponge block evenly spreads the oil on the dough to avoid uneven or excessive oil distribution;

[0028] 4. The sliced ​​dough falls onto the movable plate. When the slicing roller and the rotating shaft rotate, the rotating shaft drives the movable shaft to rotate synchronously through the first belt. The movable shaft rotates through the first cam to drive the movable plate to move up and down repeatedly relative to the processing frame, so as to scatter the dough on the movable plate to prevent the dough sheets from sticking to each other. At the same time, the dough on the movable plate is shaken off onto the conveyor belt, which is convenient for subsequent processing.

[0029] 5. When the shaft rotates to perform slicing, the second belt drives the connecting shaft to rotate. The connecting shaft rotates to repeatedly lift the sliding plate and the block through the cam to add oil to the sponge block. This can avoid the oil outlet being open all the time during work to over-oil the sponge block and waste raw materials. It can also be started and stopped according to the working status of the shaft, thereby improving the coordination and reliability between structures. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1, a slicer for processing fried noodles, such as Figure 1 As shown, it includes a processing frame 1 and a conveying frame 2 located below the processing frame 1, and conveyor belts 3 are driven on the processing frame 1 and the conveying frame 2. The processing frame 1 is provided with a dough pressing component 4, an oiling component 5, a noodle cutting component 6 and a slicing component 7 in sequence along the conveying direction of the conveyor belt 3. The kneaded dough is transported along the conveyor belt 3 of the processing frame 1 in the shape of strips. The dough pressing component 4 is used for rolling the dough into a dough cake, the oiling component is used for oiling the surface of the dough cake, the noodle cutting component 6 is used for evenly cutting the dough cake into strips, and the slicing component 7 is used for cutting the strip dough cake into slices.

[0039] like Figure 1 As shown, the dough pressing assembly 4 includes a bracket 41 fixed on both sides of the processing frame 1 and a dough pressing roller 42 rotatably connected between the brackets 41 on both sides, so that the dough is squeezed into a flat shape by the dough pressing roller 42 when passing through the dough pressing roller 42, which is convenient for subsequent cutting and processing.

[0040] like Figure 1-2As shown, the noodle cutting assembly 6 includes a lifting frame 61 arranged on the processing frame 1 and a plurality of equidistantly arranged connecting plates 62 sliding on the lifting frame 61, a noodle cutting knife 63 is fixed to the bottom end of the connecting plate 62, lifting cylinders 64 are fixed on both sides of the processing frame 1, the lifting frame 61 is fixed between the output ends of the lifting cylinders 64 on both sides, the lifting cylinders 64 drive the lifting frame 61 to descend so that the noodle cutting knife 63 is in a working state, and the noodle cutting knife 63 can cut the passing dough into long strips at equal intervals. At the same time, because there is a thin film of oil on the dough, the dough and the noodle cutting knife 63 will not stick to each other, and the noodle cutting knife 63 can slide through the dough more easily.

[0041] like Figure 2 As shown, a connecting rod 65 perpendicular to the conveying direction of the conveyor belt 3 is fixed on the lifting frame 61, and a connecting plate 62 is inserted and slid on the connecting rod 65. The lifting frame 61 is rotatably connected to an adjusting shaft 66. A plurality of limiting grooves 67 are provided on the adjusting shaft 66. The limiting groove 67 located in the middle is vertically arranged along the wall surface of the adjusting shaft 66, and the other limiting grooves 67 are symmetrically distributed along the limiting groove 67 located in the middle and the ends are inclined toward the middle. A limiting block 68 sliding in the limiting groove 67 is fixed on the connecting plate 62. An adjusting motor 69 for driving the adjusting shaft 66 to rotate is installed on the lifting frame 61. The adjusting motor 69 is started to drive the adjusting shaft 66 to rotate. The adjusting shaft 66 rotates to control the sliding of the limiting block 68 through the limiting groove 67, so that the plurality of connecting plates 62 slide along the direction of the connecting rod 65 to adjust the spacing between the connecting plates 62, thereby adjusting the spacing between the cutting knives 63, so that the cutting knives 63 can cut noodles of different widths, thereby improving production flexibility.

[0042] like Figure 1 , 3 As shown, the oiling assembly 5 includes an oil tank 51 fixed on the processing frame 1, an oil outlet 52 arranged below the oil tank 51, a blocking block 53 sliding on the oil tank 51 and covering the oil outlet 52, and a sponge block 54 fixed to the oil tank 51 and located below the oil outlet 52.

The oil tank 51 is filled with edible oil, and the blocking block 53 is used to block the oil outlet 52. When the blocking block 53 rises, the oil outlet 52 is opened, and the edible oil in the oil tank 51 overflows from the oil outlet 52 to the sponge block 54. The sponge block 54 evenly spreads the oil on the dough. When the blocking block 53 falls, the oil outlet 52 is closed.

[0043] like Figure 1 , 4As shown, the slicing assembly 7 includes a fixed frame 71 fixed between the end of the processing frame 1 and the conveying frame 2, two slicing rollers 72 located above the conveying frame 2 and rotating on the fixed frame 71, and slicing knives 73 fixed to the slicing rollers 72 and uniformly arranged along the circumference of the slicing rollers 72. A driving motor 74 for driving the slicing rollers 72 to rotate is installed on the fixed frame 71. The slicing rollers 72 are fixed with a rotating shaft 75 that rotates and extends out of the fixed frame 71. The ends of the two rotating shafts 75 are fixed with gears 76 that mesh with each other. When the conveyor belt 3 is cut into strips of noodles by the noodle cutting knife 63 and continues to convey them forward, the noodles fall from the conveyor belt 3 to between the slicing rollers 72 on both sides. The driving motor 74 drives the slicing roller 72 on one side to rotate, and drives the slicing roller 72 on the other side to rotate in the opposite direction through the meshing of two gears 76. Then, the slicing rollers 72 on both sides rotate in the opposite direction to cut the noodles into sheets uniformly through the slicing knives 73, so as to achieve the shape of the finished product. The sheet-shaped noodles fall onto the conveyor belt 3 of the conveying frame 2 and continue to be conveyed forward, which is beneficial to the subsequent frying work.

[0044] like Figure 4 As shown, the processing frame 1 is hinged with an inclined movable plate 8 located below the slicing roller 72, and the fixed frame 71 is rotatably connected with a movable shaft 9. A first belt 10 is sleeved between one end of the movable shaft 9 and the end of the rotating shaft 75. The other end of the movable shaft 9 is located below the movable plate 8 and is fixed with a first cam 11. The sliced ​​dough falls onto the movable plate 8. When the slicing roller 72 and the rotating shaft 75 rotate, the rotating shaft 75 drives the movable shaft 9 to rotate synchronously through the first belt 10. The rotation of the movable shaft 9 drives the movable plate 8 to move up and down repeatedly relative to the processing frame 1 through the first cam 11, so as to scatter the dough on the movable plate 8 to avoid adhesion between the sliced ​​dough, and at the same time, the dough on the movable plate 8 is shaken off onto the conveyor belt 3, which is convenient for subsequent processing.

[0045] like Figure 1 , 5As shown, a slot 55 is provided at the upper end of the sponge block 54 for the bottom end of the blocking block 53 to extend into, sliding plates 56 that slide out of the sponge block 54 are fixed on both sides of the blocking block 53, and fixed plates 57 are fixed on both sides of the oil tank 51. The sliding plate 56 is fixed with a slide rod 58 that inserts and slides on the fixed plate 57, and a telescopic spring 59 that is sleeved on the outside of the slide rod 58 is fixed between the sliding plate 56 and the fixed plate 57. The processing frame 1 is rotatably connected with a connecting shaft 12 on both sides, and a second cam 13 that contacts the sliding plate 56 is fixed at one end of the connecting shaft 12. A second belt 14 is sleeved between the end of the connecting shaft 12 away from the second cam 13 and the end of the rotating shaft 75. When the rotating shaft 75 rotates When slicing is performed, the second belt 14 drives the connecting shaft 12 to rotate. The connecting shaft 12 rotates to repeatedly lift the sliding plate 56 and the blocking block 53 through the cam. When the cam moves away, the sliding plate 56 drives the blocking block 53 to move down and close the oil outlet 52 under the pressure of the telescopic spring 59, so that the oil outlet 52 is repeatedly opened and closed, and the edible oil in the oil tank 51 overflows in a limited manner from the groove 55 to the sponge block 54 to add oil to the sponge block 54. This can avoid the oil outlet 52 being kept open during work to over-oil the sponge block 54 and waste raw materials. It can also be started and stopped according to the working state of the rotating shaft 75, thereby improving the coordination and reliability between the structures.
