Description

Technical Field

[0001] The utility model relates to the technical field of dough processing devices, in particular to a powder sprinkling mechanism for a dough conveying device. Background Art

[0002] Chinese patent application number 201822132836.3 discloses a continuous calender for ramen noodles that is easy to control powder sprinkling, including a machine body, a box body, a powder sprinkling roller with bristles, and a driver for driving the powder sprinkling roller to rotate. The box body is fixed to the machine body, and a powder sprinkling net with powder sprinkling holes is provided at the bottom of the box body. It also includes a mask with hooks fixed at both ends of the mask. Fixed grooves are provided on both sides of the box body along the length direction of the box body. The mask is elastic and the hooks are hooked on the fixed grooves.

[0003] In the above technical solution, the flour is preliminarily stored in the box on the machine body, and the flour is brought out by the powder roller with bristles to achieve powder spreading. This can prevent the friction between the flour from causing the flour to pile up, facilitate the spreading of the flour, and improve the falling and powder spreading effects of the flour. However, the inevitable friction between the flour will still cause the flour above the powder roller to accumulate, and only the flour directly above the powder roller will fall, while the flour near the inner wall of the box and the lower inclined surface of the inner wall cannot fall, resulting in the flour remaining in an area near the inner wall of the box and the lower inclined surface of the inner wall. Human intervention is required to refill it above the powder roller, and then the powder roller will bring it out to achieve powder spreading, which requires frequent manual supervision. Utility Model Content

[0004] The utility model aims to provide a powder sprinkling mechanism for a dough conveying device which can reduce the amount of flour retained in a box during the flour falling and sprinkling processes.

[0005] To achieve the above-mentioned purpose, the utility model discloses a powder sprinkling mechanism for a dough conveying device, comprising a storage bin, a power assembly arranged at one end of the storage bin and a sprinkling roller arranged in the storage bin, the storage bin comprising a left side plate located on the left, a right side plate located on the right and a front end plate and a rear end plate located at the front and rear ends, the left side plate comprising a first vertical portion at the upper end and a first inclined portion at the lower end of the first vertical portion, the right side plate comprising a second vertical portion at the upper end and a second inclined portion at the lower end of the second vertical portion, the first inclined portion and the second inclined portion gradually converge from top to bottom, the transition between the first vertical portion and the first inclined portion is lower than the transition between the second vertical portion and the second inclined portion, and the sprinkling roller drives the flour in the storage bin to move from the first inclined portion to the second inclined portion.

[0006] When it is necessary to sprinkle flour on the dough during transportation, the power component drives the spreading roller to rotate, and the spreading roller carries flour through friction. When the outer surface of the spreading roller rotates to the lower side of the first inclined portion and the second inclined portion, the flour falls, thereby completing the powder sprinkling. The first inclined portion and the second inclined portion located on the lower side of the storage bin can prevent flour from leaking from the lower edge of the storage bin, thereby improving the storage effect. The lower side of the second inclined portion is the discharge side.

[0007] The utility model makes the transition point between the first vertical portion and the first inclined portion lower than the transition point between the second vertical portion and the second inclined portion, thereby preventing flour located on one side of the first vertical portion from remaining on the left side plate, thereby reducing flour retention on the left side plate, causing the flour to be filled onto the spreading roller under the action of gravity, and eliminating the need for frequent human intervention to refill the flour in the storage bin onto the top of the spreading roller.

[0008] The power assembly is any existing power mechanism for driving the spreading roller to rotate, such as a motor or a motor connected to a speed change.

[0009] Preferably, the transition point between the first vertical portion and the first inclined portion is no higher than the limit position on the outer circumferential surface of the spreading roller, thereby facilitating the spreading roller to drive the flour in the storage bin to the side of the second inclined portion.

[0010] Preferably, the inclination angle of the first inclined portion is greater than the inclination angle of the second inclined portion.

[0011] By designing the left plate on the left and the right plate on the right in the storage bin, and designing the inclined parts on the lower sides of the two side plates differently, the bristles on the outer surface of the spreading roller drive the flour to spread the flour. Due to the larger inclination angle of the discharge side, the component of gravity along the inclined surface is greater than the friction between the flour, so that the side plate on the discharge side can be filled to the surrounding area of the spreading roller autonomously, so that the flour above the spreading roller and on the side of the side plate close to the discharge side can be brought out by the spreading roller, reducing the flour retained on the inclined part on the discharge side, and eliminating the need for frequent human intervention to refill the flour in the storage bin to the top of the spreading roller.

[0012] Preferably, a grid structure is provided on the lower side of the storage bin, and when the spreading roller rotates, the grid structure can prevent the flour from falling in lumps and only falls in powder form.

[0013] The grid structure may be any existing mesh with a pore size that is suitable for allowing flour to fall in powder form, thereby keeping the flour loose, making it easier to sprinkle the flour and improving the flour falling and sprinkling effects.

[0014] Preferably, the storage bin is provided with fixing parts, and at least two fixing parts are provided and are respectively located on both sides of the length direction of the storage bin, and the storage bin is connected to the power assembly through the fixing parts.

[0015] The fixing part can be any existing workpiece for fixing the storage bin, such as a bolt, a welding layer formed by welding material in a molten state, etc.

[0016] Preferably, the fixing part includes a fixed block and a fixed screw fixed to the outer surface of the storage bin. There are four fixed blocks and they are respectively located on both sides of the length direction of the storage bin. There are two fixed screws, each of which passes through the fixed block on the same side. One end of the screw is threadedly connected to the power assembly, and the other end of the screw is provided with a knob.

[0017] By fixing the screw rod through the fixed block on the same side, the distance between the storage bin and the power assembly can be adjusted after the storage bin is fixed to the power assembly by the fixed screw rod, and the storage bin can be removed by flipping the screw rod, which is convenient for the staff to disassemble and assemble; the knob facilitates manual assembly.

[0018] Preferably, a sleeve for wrapping the screw rod is provided between the two fixing blocks on the same side.

[0019] The sleeve can prevent flour driven by the flowing air in the production workshop from falling directly onto the surface of the screw, thereby protecting the screw and preventing the flour from getting stuck in the screw when the worker turns it.

[0020] Preferably, a matching cover is provided on the upper side of the storage bin, thereby protecting the flour from being carried away by the air flowing in the production workshop while not affecting the workers adding flour. The utility model can reduce the amount of flour retained on the inclined portion on the discharge side, and does not require frequent human intervention to refill the flour in the storage bin onto the spreading roller, which has the advantage of not requiring frequent manual supervision.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Depend on Figure 1 As shown, this embodiment discloses a powder sprinkling mechanism for a dough conveying device, comprising a power assembly 11 provided on the dough conveying device and a storage bin 12 provided on the power assembly 11, a spreading roller 14 which can rotate relative to the inner wall of the storage bin 12 is provided in the storage bin 12, bristles 141 are provided on the spreading roller 14, the axial direction of the spreading roller 14 is parallel to the length direction of the storage bin 12, one axial end of the spreading roller 14 passes through the storage bin 12 and is connected to the power assembly 11, the other axial end of the spreading roller 14 is connected to the inner wall of the storage bin 12 through the bearing seat 13, the power assembly 11 is any existing method for driving the spreading roller 14 to rotate The movable power mechanism is a motor or a motor connected to a variable speed motor. The side plates of the storage bin 12 on both sides of the outer cylindrical surface of the spreading roller 14 include a vertical portion and an inclined portion located below the vertical portion, so that the lower side of the storage bin 12 is retracted. The two inclined portions are respectively a first inclined portion 121 and a second inclined portion 122. The inclination angle of the first inclined portion 121 is greater than the inclination angle of the second inclined portion 122. The first inclined portion 121 and the second inclined portion 122 are respectively tangent to the outer cylindrical surface of the spreading roller 14, thereby preventing flour from leaking from the lower edge of the storage bin 12 and improving the storage effect. One side of the first inclined portion 121 is the discharge side.

[0026] Depend on Figure 2 As shown, an arc-shaped concave bag net 15 is provided on the lower side of the storage bin 12. The bag net 15 is made of hard material. The axis of the bag net 15 coincides with the axis of the spreading roller 14, so that the bag net 15 is in contact with the spreading roller 14, ensuring that when the rotating spreading roller 14 drives the bristles 141 to rotate, the ends of the bristles 141 can be in contact with the bag net 15. When the power component 11 drives the spreading roller 14 to rotate, the rotating spreading roller 14 drives the bristles 141 to rotate, and the ends of the bristles 141 are in contact with the lower edge of the storage bin 12 and the bag net 15. The bag net 15 takes away the flour carried by the ends of the bristles 141. Under the power provided by the ends of the bristles 141 and the action of gravity, the flour is sprinkled onto the dough, so that the flour is kept in a loose state and sprinkled, thereby improving the falling and sprinkling effects of the flour.

[0027] When the spreading roller 14 rotates, the net 15 can prevent the flour from falling in the form of lumps and only falls in the form of powder.

[0028] The storage bin 12 is provided with a fixing part, which includes a fixing block 16 fixed to the outer surface of the storage bin 12 and a fixed screw. There are four fixing blocks 16 and they are respectively located on both sides of the length direction of the storage bin 12. There are two fixed screws, each of which passes through the fixed block 16 on the same side. The storage bin 12 is connected to the power component 11 through the fixed screw. One end of the fixed screw is threadedly connected to the power component 11, and the other end of the screw is provided with a knob 18. A sleeve 17 for wrapping the fixed screw is provided between the two fixed blocks 16 on the same side.

[0029] The staff uses the knob 18 to pass one end of the fixed screw through the fixed block 16 and the sleeve 17 located on the same side, and makes it threadedly connected to the power component 11, thereby completing the installation and fixation of the storage bin 12.

[0030] The upper side of the storage bin 12 is provided with a corresponding cover (not shown in the figure). When the dough skin needs to be sprinkled with powder during the conveying process, the power assembly 11 drives the spreading roller 14 to rotate. The spreading roller 14 rotates relative to the inner wall of the storage bin 12 through the bearing seat 13. The spreading roller 14 with bristles 141 carries flour through friction. When the bristles 141 on the outer surface of the spreading roller 14 rotate to the bag net 15, the bag net 15 takes away the flour carried by the ends of the bristles 141. Under the power provided by the ends of the bristles 141 and the action of gravity, the flour is sprinkled onto the dough skin, thereby completing the powdering. In this process, the spreading roller 14 moves along the second inclined portion 122 The path from the first inclined portion 121 to the net 15 is rotated, so that one side of the first inclined portion 121 is the discharging side. The flour located above the first inclined portion 121 has a larger inclination angle of the first inclined portion 121, so that the component of gravity along the inclined surface is greater than the friction between the flour, so that the flour located on one side of the first inclined portion 121 can be filled to the surrounding area of the spreading roller 14 independently, so that the flour located on one side of the first inclined portion 121 can be brought out by the spreading roller 14 without manual intervention, thereby reducing the frequency of manual intervention and supervision.
