Abstract
Description
Technical Field
[0001] The invention relates to the technical field of food processing machinery, in particular to a kneading type pasta processing equipment. Background Art
[0002] Noodles are a common food in northern my country, and the production of noodle requires multiple steps such as dough mixing, kneading, and dough forming. For large-scale food processing departments, mechanical equipment is usually used to replace manual operations such as dough mixing and forming.
[0003] At present, the dough kneading mechanisms of common pasta processing equipment on the market can be roughly divided into two categories: horizontal mixers and vertical mixers. Most products adopt a horizontal structure, that is, the stirring shaft is horizontally installed in a square mixing box. In actual use, the dough kneading mechanism of this structure has problems such as poor dough kneading effect and pasta taste, and low efficiency. The reasons are as follows:
[0004] Since the stirrer is arranged horizontally, the stirring teeth or blades and other parts move in a circular motion around the stirring axis during operation. The plane formed by the motion trajectory is perpendicular to the bottom plate of the box. The stirring teeth and other parts turn the dough (or ingredients) up and down around the axis. The stirring action is simple and different from the traditional manual dough kneading method. Since this stirring method lacks kneading and pressing action, it not only needs to increase the stirring time appropriately, but also the kneading effect of the dough and the taste of the finished pasta are far inferior to the traditional processing method. During the dough kneading process, larger dough is easy to stick to the stirring teeth, shafts and other parts, and small pieces of dough or debris are thrown and hit by the stirring teeth and accumulated at the corners of the box. Once the above situation occurs, it is often necessary to stop the machine for processing, which not only affects the taste of the ingredients, but also indirectly reduces the processing efficiency. This problem is particularly obvious for soft dough such as fried dough sticks and vermicelli. Another disadvantage of the horizontal structure is that due to the structural limitations of the horizontal stirrer, it is necessary to bypass the stirrer parts when cleaning the inside of the box, which is time-consuming and laborious.
[0005] In addition, there are a few dough kneading devices with vertical mixers that only change the stirring direction of the ingredients, while problems such as low operating efficiency of horizontal structure products, lack of kneading of dough blanks, and poor taste of finished pasta products have not yet been solved. Summary of the invention
[0006] In view of the above problems, the present invention provides a kneading type pasta processing equipment, which adopts a vertical agitator and a horizontal spiral push rod to push the dough in both vertical and horizontal directions, simulating the traditional manual kneading technique to improve the dough kneading efficiency and the taste of pasta.
[0007] The purpose of the present invention is achieved through the following technical solutions:
[0008] A kneading type pasta processing equipment:
[0009] It includes a main frame, a power device installed on the main frame, a control system connected to the power device and a transmission mechanism; it also includes a dough kneading barrel, a screw push rod, a stirrer, a stirrer support, and a lifter;
[0010] The dough mixing barrel is fixedly connected to the main frame, the top of the dough mixing barrel is a feed inlet, and the lower side wall is provided with a discharge outlet; the spiral push rod is horizontally installed in the dough mixing barrel, and the end of the spiral push rod corresponds to the position of the discharge outlet of the dough mixing barrel;
[0011] The stirrer support includes a column, a lifting bracket, and a shaft seat. The column is vertically arranged on the side of the dough barrel and fixedly connected to the main frame; the lifting bracket is rotatably mounted on the column and can slide axially along the column; the free end of the lifting bracket is provided with a shaft seat, and the stirring end of the stirrer is vertically assembled on the shaft seat downward. When working, the stirrer is suspended above the spiral push rod and is perpendicular to the spiral push rod;
[0012] The rotation of the lifting bracket can drive the agitator to rotate around the axis of the column;
[0013] The lifter is fixed on the main frame, and the lifter is connected to and drives the lifting bracket to rise and fall along the column, so that the stirrer enters and exits the barrel body from the feeding port of the dough barrel;
[0014] A positioning mechanism for locking the lifting bracket is provided between the lifting bracket and the column or the main frame;
[0015] The screw push rod, stirrer and lifter are connected with the power device through a transmission mechanism.
[0016] Furthermore, the column is a hollow structure, and a first transmission half-shaft is installed inside it along the center line of the column; a second transmission half-shaft is installed on the lifting bracket, and the first transmission half-shaft and the second transmission half-shaft are coaxially arranged and connected through splines and spline sleeves to achieve power transmission or disconnection; the second transmission half-shaft is connected through a shaft or chain drive and drives the agitator to rotate.
[0017] Furthermore, the bottom plate of the dough kneading barrel is in a groove-like structure to form a conveying groove, and the spiral push rod is arranged along the conveying groove.
[0018] Furthermore, the upper section of the barrel wall of the dough kneading barrel is a cylindrical structure, and the lower section is a square column structure, and the barrel walls of the cylindrical section and the square column section have a smooth transition.
[0019] Furthermore, there are two spiral push rods, which are arranged in parallel, have the same pushing direction and opposite rotation directions.
[0020] Furthermore, the stirrer structure comprises a stirring shaft and a plurality of fins fixed on the stirring shaft in the shape of paddle blades, and the fins surround the stirring shaft and are spaced apart along the axial direction.
[0021] Furthermore, the lifter adopts a lifting screw mechanism, a hydraulic device, a lifting chain or a winch.
[0022] The beneficial effects of the present invention are:
[0023] The agitator is arranged vertically, and the height of the agitator shaft can be controlled by a lifter to cooperate with the spiral push rod at the bottom of the dough kneading barrel. The spiral push rod is used to push the dough ingredients to the bottom corner of the dough kneading barrel, forcing the dough ingredients to surge upward along the barrel wall, and are pressed down by the agitator fins and sent to the other side of the barrel bottom, and then pushed back to the bottom corner of the dough barrel by the spiral push rod again, simulating the manual dough kneading technique to repeatedly knead the dough, greatly enhancing the taste of the finished pasta and improving the dough kneading efficiency. Since the dough kneading operation is concentrated in the lower section of the barrel, in the process of kneading the ingredients to gradually form the dough, it always rotates between the spiral push rod and the agitator fins, avoiding the dough from being thrown up, and completely solving the problem of dough splashing and equipment adhesion in the existing product box.
[0024] Another advantage of this product is that the stirrer can be lifted out of the dough mixing barrel by means of a lifter and rotated around a column to the side of the barrel, so that the inside of the barrel and the stirrer can be easily cleaned.
[0025] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

Example
[0030] from Figure 1 to Figure 3 It can be seen that the technical solution of the present invention includes a main frame 1, a power device 2 installed on the main frame, a control system and a transmission mechanism connected to the power device, a dough kneading barrel 3, a screw push rod 12, a stirrer 4, a stirrer support, and a lifter;
[0031] The dough mixing barrel 3 is fixedly connected to the main frame 1, the top opening of the dough mixing barrel 3 is a feed inlet, and the lower side wall of the dough mixing barrel is provided with a discharge port 3a;
[0032] The screw push rod 12 is horizontally installed in the lower part of the dough mixing barrel 3, and one end of the screw push rod 12 corresponds to the position of the discharge port 3a of the dough mixing barrel. For the convenience of description, the end corresponding to the discharge port 3a is called the end, that is, the end of the screw push rod 12 points to the discharge port 3a of the dough mixing barrel;
[0033] The stirrer support includes a column 9, a lifting bracket 6, and an axle seat 5. The column 9 is vertically installed on the side of the dough barrel 3 and fixedly connected to the main frame 1; a pipe column is provided at one end of the lifting bracket 6, and the lifting bracket is rotatably mounted on the column 9 through the pipe column and can slide axially along the column; the other end of the lifting bracket 6 (i.e., the free end of the lifting bracket) is provided with a shaft seat 5, and the stirring end of the stirrer 4 is vertically assembled downward on the shaft seat 5. When working, the stirring end of the stirrer is suspended above the screw push rod 12 and is perpendicular to the screw push rod; when the lifting bracket 6 rotates, it can drive the stirrer 4 to revolve around the axis of the column 9;
[0034] The lifter is fixed on the main frame 1. The lifter in this embodiment adopts a lifting screw mechanism, which is composed of a lifting screw 7 vertically mounted on the main frame and a fork 10 (screw nut) threaded with the lifting screw 7 to form a screw pair. The fork 10 is engaged with the card position on the lifting bracket 6. The lifting screw 7 is rotated to make the fork 10 move up and down along the screw, and drive the lifting bracket 6 to slide and lift along the axial direction of the column 9, so that the agitator 4 can enter and exit the barrel from the feeding port of the dough mixing barrel 3. The lifter can also use conventional means such as hydraulic devices, lifting chains or winches to realize the lifting of the lifting bracket.
[0035] A positioning mechanism 11 for locking the lifting bracket 6 is provided between the lifting bracket 6 and the column 9 or the main frame 1 to prevent displacement between the lifting bracket and the column. The positioning mechanism can be a clamp and set at the lower end of the column of the lifting bracket, or a conventional structure such as a jackscrew can meet the requirements.
[0036] The screw push rod 12, the agitator (shaft), and the lifter are all connected to the power device 2 through a transmission mechanism. The power device, control system, and transmission mechanism described in this application can meet the requirements by using existing conventional technologies. According to the power requirements of the agitator, screw push rod, and other components, bidirectional motors of corresponding power can be selected to control them separately. Alternatively, a bidirectional motor can be used in conjunction with a clutch device to provide power for each component to reduce the manufacturing cost.
[0037] During the dough kneading operation, the lifting bracket 6 is lowered by the lifter, so that the agitator 4 enters the dough kneading barrel 3 from the top feed port and is suspended above the spiral push rod 12. The spiral push rod 12 and the agitator 4 rotate perpendicularly to each other to push the ingredients toward the corner of the barrel (i.e., the barrel wall on the opposite side of the dough kneading barrel from the feed port) in the horizontal and vertical directions and knead the dough repeatedly, simulating the manual dough kneading method.
[0038] When cleaning the barrel after the dough kneading operation is completed or when adding flour again, the lifting bracket 6 and the stirrer 4 can be lifted to the outside of the barrel by the lifting device, and the lifting bracket can be pushed to rotate around the column to move the stirrer to the side of the dough kneading barrel. At this time, the stirrer is completely exposed outside the barrel. In order to prevent injuries caused by misoperation, the transmission mechanism of the stirrer adopts a two-stage transmission shaft design that can be clutched, and its structure is as follows:
[0039] The column 9 adopts a hollow structure, and a first transmission half shaft 8a is installed inside it along the center line of the column, and a second transmission half shaft 8b is installed on the lifting bracket 6, so that the first transmission half shaft 8a and the second transmission half shaft 8b are coaxially arranged and connected through splines and spline sleeves to transmit or disconnect power; the second transmission half shaft 8b is connected through a shaft or chain drive and drives the agitator shaft to rotate.
[0040] When the lifting bracket 6 is lowered until the agitator enters the barrel, the splines of the first and second transmission half-shafts engage with the spline sleeves to realize power transmission; when the lifting bracket 6 is lifted to raise the agitator out of the barrel, the second transmission half-shaft 8b goes up with the lifting bracket 6, and the splines between the two half-shafts are separated from the spline sleeves to cut off the power to ensure the safety of the operator.
[0041] In order to facilitate the collection of food materials at the bottom of the barrel, as an optimization solution, the barrel bottom plate of the dough barrel 3 can be made into a groove-shaped structure to form a conveying trough 3b, and the discharge port 3a of the dough barrel is set at the end of the conveying trough 3b. The spiral push rod 12 is arranged along the conveying trough, and the bottom plate of the conveying trough 3b is processed into a curved surface to match the shape of the spiral push rod to avoid blind spots or dead angles between the bottom of the trough and the push rod. In this embodiment, two spiral push rods 12 are arranged horizontally and side by side in the conveying trough. The cross-section of the bottom of the trough is wavy and matched with the two spiral push rods. The two spiral push rods have the same propulsion direction and opposite rotation directions.
[0042] As another optimization scheme, the agitator 4 structure is composed of a stirring shaft 4a and a plurality of fins 4b fixed on the stirring shaft in the shape of paddles. Each fin 4b surrounds the stirring shaft 4a and is spaced apart along the axial direction of the stirring shaft, that is, the fins are arranged in layers to press the fabric ingredients that rise to different heights in the barrel back to the bottom of the barrel.
[0043] Another optimization scheme is that the upper section of the barrel body of the dough kneading barrel 3 is a cylindrical structure, which is used to cooperate with the rotation trajectory of the vertical fins of the stirrer 4 to prevent the occurrence of a mixing blind spot on the barrel wall; the lower section of the barrel body of the dough kneading barrel is a square columnar structure, which cooperates with the horizontal spiral push rod, and the barrel walls of the cylindrical section and the square column section should have a smooth transition.
[0044] Using this equipment to process pasta can greatly reduce labor costs, reduce labor intensity, and improve work efficiency. The working process is as follows:
[0045] First, add flour into the dough kneading barrel 3, start the lifter and drive the lifting bracket 6 downward along the column through the fork 10, so that the stirrer enters the dough kneading barrel from top to bottom, and lowers the stirrer to a suitable height according to the amount of flour and makes it hover above the spiral push rod 12; slowly inject water into the barrel, and start the stirrer and the spiral push rod to stir. During this process, the propulsion direction of the spiral push rod should be set to push from the end of the conveying trough 3b to its front end, and the rotation direction of the stirrer should ensure that the deflection angle of its fins 4b pushes downward, that is, the spiral push rod pushes the food away from the discharge port 3a, forcing the food accumulated at the front end of the conveying trough to surge upward, and is pressed down by the stirrer fins 4b to stir to the middle and rear section or the end of the conveying trough, and then pushed back to the front end of the conveying trough by the spiral push rod 12, simulating manual kneading and pressing repeatedly, which greatly enhances the taste of the food.
[0046] After the dough is kneaded, the stirrer stops rotating and the spiral push rod rotates in the opposite direction, that is, the dough is pushed in the opposite direction along the conveying trough to be discharged from the dough mixing barrel through the discharge port 3a. If the dough accumulates and blocks the discharge port, the stirrer can be started to rotate in the opposite direction, and the fins 4b can be used to lift the dough to relieve the congestion.
[0047] After the dough kneading operation is completed, the lifter is started to drive the lifting bracket 6 upward to lift the agitator out of the dough kneading barrel, and the lifting bracket is pushed to make the agitator leave the barrel mouth, and the barrel is cleaned or flour is added again.
[0048] This equipment can be used with various pasta forming equipment, such as Figures 1 to 3 As shown, the discharge port 3a of the device is connected to the feed port of the steamed bread machine 13. After the dough is kneaded, the dough is directly introduced into the steamed bread machine for cutting and kneading, eliminating the need to transfer the dough between the two devices, saving time and effort.
[0049] Finally, it should be noted that the above embodiments are used to illustrate the technical solution of the present invention rather than to limit it. Technicians in the relevant field may modify the implementation methods or make equivalent substitutions for some technical features without departing from the essence of the technical solution of the present invention, and all of these should be included in the scope of protection required by the present invention.
