Description

Technical Field

[0001] This utility model relates to the field of food processing machinery and equipment technology, and in particular to a feeding device for a dough mixer. Background Technology

[0002] A dough mixer is a core piece of equipment in pasta processing, used to mix flour with water and other ingredients to form dough. In actual production, flour is usually lifted from the storage silo and quantitatively fed into the dough mixer.

[0003] Currently, the most common feeding method uses a simple screw conveyor. Although this method is simple in structure, it has the following obvious shortcomings: easy clumping and bridging: especially flour that has been damp or left to stand for a long time, is prone to clumping in the hopper or forming a "bridging" phenomenon at the outlet, resulting in poor feeding and conveying interruption, requiring manual intervention and affecting the continuity and efficiency of automated production; inaccurate quantitative feeding: traditional screw conveyors are difficult to achieve high-precision quantitative feeding. For processes that require strict control of the flour-to-water ratio, inaccurate feeding will directly affect the quality and stability of the dough.

[0004] Therefore, in response to the existing problems of clumping and quantitative control, a feeding device for dough mixers is needed to solve these problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device for a dough mixer. This invention ensures that the flour is homogeneous and loose through the synergistic effect of reciprocating scraping and high-speed crushing; and it ensures consistent flour feeding by using a compressed sleeve volume for precise measurement, thereby stabilizing the flour-to-water ratio and improving the quality of dough mixing.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A feeding device for a dough mixer includes a base, a box body fixedly connected to the top of the base, a support slidably connected to the inner wall of the box body, a first hydraulic column fixedly connected to the right side of the top of the support, a sleeve fixedly connected to the driving end of the first hydraulic column via a metering component, a first movable door installed on the inner wall of the top of the box body, a hopper fixedly connected to the top of the box body, a feed pipe fixedly connected to the top of the hopper body, a motor installed on the top of the hopper body, a first rotating shaft fixedly connected to the driving end of the motor via an anti-caking component, and a spiral blade fixedly connected to the outer wall of the bottom end of the first rotating shaft.

[0008] As a further improvement of this utility model, the anti-caking component includes half gears connected to the upper and lower sides of the outer wall of the top end of the first rotating shaft. The outer walls of the half gears are meshed with movable plates. The upper and lower ends of the movable plates are fixedly connected with baffles. The front and rear ends of the movable plates are fixedly connected with arc-shaped plates. Blades are installed on the upper and lower sides of the outer wall of the first rotating shaft.

[0009] As a further improvement of this utility model, the quantitative component includes a second movable door installed at the bottom end of the sleeve, a fixing ring fixedly connected to the top end of the support, and a conveyor belt installed at the bottom end of the base.

[0010] As a further improvement of this utility model, the inner wall of the arc-shaped plate is slidably connected to the front and rear ends of the baffle, and the baffle is provided with a sliding groove adapted to the arc-shaped plate.

[0011] As a further improvement of this utility model, the outer wall of the sleeve is slidably connected to the inner wall of the fixing ring, and the bottom end of the support is fixedly connected to a second hydraulic column.

[0012] As a further improvement of this utility model, a second rotating shaft is fixedly connected to the right end of the first movable door, and a second rotating shaft is fixedly connected to the right end of the second movable door.

[0013] As a further improvement of this utility model, a water tank is fixedly connected to the top left side of the base, a water pump is installed on the inner wall of the water tank, a water pipe is fixedly connected to the output end of the water pump, and several pipe clamps are fixedly connected to the outer wall of the water pipe, with the bottom ends of the pipe clamps all fixedly connected to the top of the base.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. In this utility model, the two actions of reciprocating scraping and high-speed crushing are organically combined. On the one hand, the arc plate actively scrapes the static flour at the edge of the bin and the dead corner at the bottom towards the center during the reciprocating motion, breaking the arching phenomenon of the material and preventing the formation of lumps. On the other hand, the high-speed rotating blades effectively cut and break up the material concentrated in the center, especially the potential lumps that are pushed in. This mechanism of "combining prevention and treatment" ensures the homogeneity and looseness of the discharged flour.

[0016] 2. In this utility model, the sleeve is driven to rise by a hydraulic column, which mechanically compresses the flour space inside the sleeve. This process eliminates gaps between materials, making them denser and achieving high-precision metering based on a fixed volume. This mechanism ensures that the amount of flour put onto the conveyor belt each time is highly consistent, thereby ensuring the stability of the flour-to-water ratio, which is crucial for ensuring the quality of dough kneading in batch production.

[0032] Example 1: A feeding device for a dough mixer includes a base 20, a box 11 fixedly connected to the top of the base 20, a support 16 slidably connected to the inner wall of the box 11, a first hydraulic column 14 fixedly connected to the right side of the top of the support 16, a sleeve 13 fixedly connected to the driving end of the first hydraulic column 14 via a metering component, a first movable door 12 installed on the inner wall of the top of the box 11, a bin 1 fixedly connected to the top of the box 11, a feed pipe 2 fixedly connected to the top of the bin 1, a motor 3 installed at the top of the bin 1, and a first rotating shaft 7 fixedly connected to the driving end of the motor 3 via an anti-caking component. The material is 40Cr or 420 stainless steel, both of which have high strength and good wear resistance, and can withstand the impact and torque of the blade 6 when crushing flour. Diameter: According to the load design, the diameter of the main load-bearing section is recommended to be Φ30mm. A spiral blade 8 is fixedly connected to the outer wall of the bottom end of the first rotating shaft 7. The material is 304 stainless steel. The size is: welded to the first rotating shaft 7, the gap between the outer diameter and the inner wall of the feeding channel is less than 2mm, and the pitch is approximately... The outer diameter is 0.8 times the outer diameter, with an outer diameter of Φ120mm and a pitch of approximately 100mm. The core working components of this device include an anti-caking component and a metering component. The anti-caking component is responsible for pre-treating the flour before it enters the conveying stage to ensure that the flour is loose and free of lumps. The metering component is responsible for accurately controlling the amount of flour conveyed to the kneading area each time to achieve quantitative feeding. The anti-caking component specifically includes half gears 9 connected to the upper and lower sides of the outer wall of the top of the first rotating shaft 7. The material is 45# steel with surface hardening or 304 stainless steel. Sufficient tooth surface hardness is required to ensure wear resistance and smooth transmission. The size is: module m=2. The number of teeth can be designed according to the reciprocating motion stroke requirements. The outer walls of the half gears 9 are meshed with moving plates 10. The upper and lower ends of the moving plates 10 are fixedly connected with baffles 4. The front and rear ends of the moving plates 10 are fixedly connected with arc-shaped plates 5. The material is 304 stainless steel. The dimensions of the arc-shaped plates 5 are: the radius of curvature matches the inner wall of the silo body 1, the height is the same as the effective height of the side wall of the silo body 1, and the plate thickness is 1.5mm, the first rotating shaft 7 has blades 6 installed on both the upper and lower sides of its outer wall. The material is 420 high-carbon stainless steel or 5Cr15MoV, ensuring high hardness and sharpness, wear resistance and not easy to chip. The size is recommended to be rectangular or fan-shaped, with a length of 80mm, a width of 20mm and a thickness of 2mm. The motor 3 drives the first rotating shaft 7 to rotate, which drives the half gear 9 on it to rotate synchronously. When the half gear 9 meshes with the toothed blocks on the inner wall of the moving plate 10, it pushes the moving plate 10 and the arc-shaped plate 5 connected to it to move to one side. When the half gear 9 disengages, the moving plate 10 moves to the other side under the action of the symmetrically distributed toothed block structure, driven by the other half gear 9 or by inertia and structural cooperation, thus forming a cyclical translational motion. The curved plate 5 on the side continuously scrapes the flour from the edge of the silo 1 towards the center. At the same time, the high-speed rotating first shaft 7 drives the blades 6 on its outer wall to effectively crush the lumpy flour. This design significantly improves the flowability of the flour and avoids uneven kneading caused by lumps. The inner wall of the curved plate 5 is slidably connected to the front and rear ends of the baffle 4. The baffle 4 has grooves that match the curved plate 5. This structure ensures the stability and trajectory accuracy of the curved plate 5 during reciprocating motion. The metering component includes a second movable door 25 installed at the bottom of the sleeve 13, a fixing ring 15 fixedly connected to the top of the support 16, and a conveyor belt 22 installed at the bottom of the base 20. Its working process is as follows: the flour after anti-lumping treatment passes through the spiral blades. Under the conveying of 8, the flour enters the casing 13 through the channel at the lower end of the silo 1. Subsequently, the second hydraulic column 24, fixedly connected to the bottom end of the support 16, actuates, pushing the support 16 and casing 13 upward, compressing the internal space of casing 13, expelling excess air and compacting the flour, thereby achieving initial volumetric metering. Materials: cylinder body is 45# steel, piston rod is 40Cr, chrome-plated for rust prevention. First hydraulic column 14 and second hydraulic column 24. Parameters: First hydraulic column 14: stroke is determined according to the moving distance of casing 13 from the receiving position to the feeding position, recommended 300mm; Second hydraulic column 24: stroke determines the compression volume of casing 13, recommended 50mm; thrust needs to be calculated and selected based on the reaction force of compressing the flour. Then, the first hydraulic... The column 14 drives the sleeve 13 to slide within the fixed ring 15, moving horizontally above the conveyor belt 22. During this movement, the structure at the top of the box 11 blocks the first movable door 12 above, preventing flour leakage. Upon reaching the designated position, the second movable door 25 at the bottom of the sleeve 13 opens, and a measured amount of flour falls onto the conveyor belt 22. A second rotating shaft 23 is fixedly connected to the right end of both the first and second movable doors 12 and 25. The second rotating shaft 23 enables the doors to open and close. Materials: Door body is made of 304 stainless steel, rotating shaft is made of 40Cr. Dimensions: Door body thickness is 2mm, recommended diameter of the second rotating shaft 23 is Φ15mm. It is equipped with a food-grade fluororubber sealing ring to ensure sealing. The structure is simple and reliable.

[0033] Example 2: To achieve automated dough mixing, a water tank 17 is fixedly connected to the top left of the base 20. A water pump 18 is installed on the inner wall of the water tank 17. A water pipe 19 is fixedly connected to the output end of the water pump 18. Several pipe clamps 21 are fixedly connected to the outer wall of the water pipe 19. The bottom ends of the pipe clamps 21 are all fixedly connected to the top of the base 20. When a certain amount of flour falls onto the conveyor belt 22, the water pump 18 starts and sprays water onto the flour through the water pipe 19. The pipe clamps 21 ensure that the position of the water pipe 19 is fixed, preventing water supply failure due to detachment or displacement, thereby achieving synchronous and quantitative mixing of flour and water.

[0034] As one of the optimized structural designs for Example 1, such as Figures 1-4 As shown, the anti-caking assembly includes half-gears 9 connected to the upper and lower sides of the outer wall of the top of the first rotating shaft 7. Movable plates 10 are meshed with the outer walls of the half-gears 9. Baffles 4 are fixedly connected to the upper and lower ends of the movable plates 10, and arc-shaped plates 5 are fixedly connected to the front and rear ends of the movable plates 10. Blades 6 are installed on the upper and lower sides of the outer wall of the first rotating shaft 7. After the motor 3 starts, it drives the first rotating shaft 7 and the half-gears 9 on it to rotate 360 ​​degrees. Since the half-gears 9 are incomplete gears, and the tooth blocks on the inner wall of the movable plates 10 are symmetrically distributed, when one side of the half-gear 9 meshes with the tooth block... When the half gear 9 disengages and the other half gear 9 engages, it drives the moving plate 10 and the arc plate 5 on that side to move in one direction. When the half gear 9 disengages and the other half gear 9 engages, it drives the moving plate 10 on the other side to move in the opposite direction, or the original moving plate 10 is reset through the linkage of the structure. This generates a cyclical translational motion. The arc plates 5 installed at the front and rear ends of the moving plate 10 scrape back and forth in the silo 1, continuously pulling the flour attached to the edge and bottom corner of the silo 1 towards the central area, effectively solving the problem of material accumulation at the edge of the silo 1.

[0035] Working principle: Flour is poured in through the feed pipe 2, and the motor 3 is turned on. The motor 3 drives the half gear 9 on the first rotating shaft 7 to rotate. When the half gear is only in contact with one side, it moves horizontally. Because the gear rotates 360 degrees and the tooth blocks on the inner wall of the moving plate 10 are symmetrically distributed, a cyclical horizontal movement is generated. The arc-shaped plates 5 at both ends of the moving plate 10 reciprocate, pulling the flour towards the center. The blades 6 on the outer wall of the first rotating shaft 7 rotate with the first rotating shaft 7, crushing the lumpy flour to prevent insufficient kneading caused by flour clumping. Then, the flour is driven from the channel at the lower end of the hopper 1 by the spiral blades 8 to... Inside the sleeve 13, the second hydraulic column 24 rises and compresses the internal space, making the amount of flour transferred each time more consistent. The first hydraulic column 14, through cyclical movement, drops the flour through the first movable door 12 onto the conveyor belt 22. When the sleeve 13 moves to the left end, the plate on the right side of the top will block the first movable door 12 above to prevent leakage. The water tank 17 on the left side of the top of the base 20 delivers water through the water pump 18 inside. The outer wall of the water pipe 19 is fixed by the pipe clamp 21 to prevent the water pipe 19 from falling off and causing water shortage. The flour on the conveyor belt 22 and the water in the water tank 17 are output simultaneously to achieve quantitative dough mixing.
