Description

Technical Field

[0001] The invention belongs to the technical field of flour production, in particular to a raw material cold grinding device for flour processing. Background Art

[0002] Flour is a powdered food ingredient made from wheat through grinding, screening and other processes. It is one of the basic raw materials for baking, cooking and the food industry. The flour processing and production process usually includes multiple steps. In the flour making process, grinding equipment is required to grind the wheat into powder.

[0003] Patent publication number CN118543409B discloses a cold grinding device for flour production. This patent provides a cold grinding device for flour production, comprising a base plate and a lower hopper. The lower hopper is mounted on the base plate via a support. A servo motor is mounted on the top center side of the lower hopper via a bracket. A gear is provided at the output end of the servo motor. The three corners of the lower hopper are connected to a lower millstone via connecting rods. An upper millstone is rotatably mounted on the lower millstone. A gear ring is provided on the outer ring of the upper millstone, and the gear rings are meshed with the gears. The device also includes a disc-shaped cooling pipe and a cooling circulation mechanism. A disc-shaped cooling pipe is provided within the cavity of the upper millstone, and a cooling circulation mechanism connected to the disc-shaped cooling pipe is provided between the lower and upper millstones. The cooling circulation mechanism, in conjunction with the disc-shaped cooling pipe, can cool the interior of the upper and lower millstones, effectively avoiding the risk of adverse changes in flour properties due to excessive temperatures during the grinding process.

[0004] However, the above technical solution still has the following deficiencies in practical application: The ground flour will fall into the collection container through the discharge port at the bottom of the lower hopper for collection. In some cases, the ground flour will be collected in a woven bag for subsequent packaging, transportation and other operations. Since the woven bag is relatively soft, when the woven bag is placed at the discharge port for receiving the material, the bag mouth may be in a folded state, which makes it difficult for the flour to fall into the woven bag accurately. Moreover, as the amount of flour inside the woven bag increases, the woven bag will continue to deform. When the flour is unevenly distributed inside the woven bag, the woven bag is prone to tilting to one side, causing the flour in the woven bag to flow out, thereby affecting the subsequent packaging, transportation and other operations of the flour. In the process of receiving the material, the workers hold the woven bag by hand to maintain its stability, which is labor-intensive. Summary of the Invention

[0016] The beneficial effects of the present invention are as follows: 1. The raw material cold grinding equipment for flour processing described in the present invention utilizes a cloth bag opening positioning assembly. When a woven bag is needed to hold flour, the opening of the woven bag can be tightened on the discharge pipe by a steel wire rope. When the ground flour falls into the woven bag through the discharge pipe for bagging, since the bag opening of the woven bag fits tightly with the discharge pipe, the flour can fall into the woven bag accurately and will not overflow from the bag opening due to splashing. Similarly, the woven bag will not tilt to one side due to deformation, causing flour to flow out. This ensures the smooth progress of subsequent operations such as packaging and transportation of flour, and also saves workers from the process of holding the woven bag to maintain its stability, thereby reducing the labor intensity of workers.

[0017] 2. The cold grinding equipment for flour processing described in the present invention utilizes a lifting component. When a woven bag receives flour, a turntable can be used to lift the bottom of the woven bag to provide support for the woven bag, thereby avoiding the situation where the bag opening of the woven bag easily slips out of the wire rope due to the increasing weight of the flour inside the woven bag.

[0018] 3. The cold grinding equipment for raw materials of flour processing described in the present invention utilizes an inflation component and a stretching component. When the flour enters the woven bag, the woven bag always remains in a stretched state, thereby avoiding the situation that the flour is unevenly distributed in the woven bag due to wrinkles after entering the woven bag, and the space inside the woven bag is difficult to be fully utilized, thereby ensuring the bagging effect of the flour. Moreover, before the woven bag is removed from the discharge pipe, the bag mouth of the woven bag can be tightened, and then the woven bag can be removed from the discharge pipe, thereby avoiding the situation that the bag mouth of the woven bag is in an open state when it is removed from the discharge pipe, which is easy to cause flour to overflow from the bag mouth of the woven bag due to careless operation or accidental touch, thereby further facilitating subsequent operations on the woven bag.

[0019] 4. The cold grinding equipment for flour processing described in the present invention can use an air cooler to evenly transport cold air to the inner cavity of the grinding cylinder through the annular pipe 2 and the air outlet pipe 1 during the grinding process to cool the grinding roller. In this way, the temperature of the flour during grinding is effectively reduced through cold grinding, avoiding the high temperature environment from destroying the trace elements and nutrients in the wheat raw materials, and ensuring the quality stability of the flour.

[0030] Specifically, in the prior art, the ground flour will fall into the collection container through the discharge port at the bottom of the lower hopper for collection. In some cases, the ground flour will be collected in a woven bag for subsequent packaging, transportation, etc. Since the woven bag is relatively soft, when the woven bag is placed at the discharge port for receiving the material, the bag opening may be in a folded state, which makes it difficult for the flour to fall into the woven bag accurately. Moreover, as the amount of flour inside the woven bag increases, the woven bag will continue to deform. When the flour is unevenly distributed inside the woven bag, the woven bag is likely to tilt to one side, causing the flour in the woven bag to flow out, thereby affecting the subsequent packaging, transportation, etc. of the flour. In addition, during the receiving process, the workers have to hold the woven bag by hand to maintain its stability, which is labor-intensive. Therefore, in order to solve the above problems, when the present embodiment is in use, the woven bag for holding the flour is placed under the grinding cylinder 3, and the bag opening is sleeved on the discharge pipe 13. At this time, the steel wire rope 24 is in a straight state and is located on the left side of the discharge pipe 13. Then, the adjusting block 21 is driven to move laterally by the cylinder 12, so that the adjusting block 21 moves from the discharge pipe 13 to the right side of the discharge pipe 13. During the movement of the adjusting block 21, the bag opening of the woven bag will be restrained by the steel wire rope 24 and fit into the surface of the discharge pipe 13. At the same time, the motor 4 22 is used to drive the roller 23 to rotate and unwind the steel wire rope 24, so that the steel wire rope 24 is always kept taut. At this time, one side of the bag opening of the woven bag is pressed against the surface of the discharge pipe 13, and then the adjusting block 21 is used to move laterally. The motor 3 19 drives the bidirectional threaded rod 1 20 to rotate, so that the two cylinders 12 approach each other, and the two ends of the wire rope 24 also approach each other until the wire rope 24 forms a U shape, and then the motor 2 11 drives the mounting plate 41 to rotate 180 degrees, so that the U-shaped wire rope 24 crosses, and then the motor 8 38 drives the gear 39 to rotate, so that the rack rod 37 slides on the mounting plate 41, and the pressure rod 40 moves laterally and approaches the angle of the intersection of the wire ropes 24, and pushes the intersection of the wire ropes 24 until the intersection of the wire ropes 24 fits the outer wall of the discharge pipe 13. At this time, the wire rope 24 is tightly fitted with the outer wall of the discharge pipe 13, and the woven bag mouth is tightened to the discharge pipe 13 by the wire rope 24. Then the wheat raw material is added to the grinding cylinder 3, and the wheat raw material is in the gap between the grinding roller 43 and the grinding cylinder 3. At the same time, the grinding roller 43 is driven to rotate by the motor 5, and the wheat raw material can be ground by the grinding roller 43. The ground flour falls into the woven bag through the discharge pipe 13 for bagging. During the whole material receiving process, since the bag opening of the woven bag is tightly fitted with the discharge pipe 13, the flour can be accurately dropped into the woven bag and will not overflow from the bag opening due to splashing. Similarly, the woven bag will not fall to one side due to deformation, resulting in flour flowing out. This ensures the smooth progress of subsequent operations such as packaging and transportation of flour, and also saves the workers from having to hold the woven bag to maintain its stability, thereby reducing the workers' labor intensity. As the amount of flour in the woven bag continues to increase, the weight of the flour inside the woven bag will also continue to increase, and the woven bag mouth will easily slip out of the steel wire rope 24, causing the woven bag to tip over and cause trouble. Therefore, in order to avoid this situation, according to the size of the woven bag, the motor 7 36 drives the threaded rod 1 35 to rotate, so as to raise the lifting plate 16, and use the turntable 31 to lift the bottom of the woven bag to provide support for the woven bag, thereby avoiding the situation that the woven bag mouth is easy to slip out of the steel wire rope 24 due to the increasing weight of the flour inside the woven bag; When the woven bag is filled with a sufficient amount of flour, the steel wire rope 24 is driven away from the bag opening and the woven bag can be removed.

[0031] In this embodiment, Figure 2-Figure 8 As shown, the support frame 2 is also provided with an inflatable component; The inflation component includes an air pump 15 fixedly connected to one side of the support frame 2. The air outlet end of the air pump 15 is connected to a connecting pipe 2 14. One end of the connecting pipe 2 14 is connected to an annular pipe 1 25. A plurality of air outlet pipes 26 are connected and fixed around the inner side of the annular pipe 25. The air outlet pipe 2 26 penetrates the discharge pipe 13, and the air outlet of the air outlet pipe 2 26 extends to the bottom of the discharge pipe 13.

[0032] A stretching component is also provided on the base 1; The stretching assembly includes a slide rod 18 fixedly connected to one side of the upper end face of the base 1, the slide rod 18 is slidably connected to the frame 17, two slide rods 2 34 are slidably connected to the middle of the four sides of the frame 17, one end of the slide rod 2 34 is fixedly connected to the finger cylinder 44, the middle of the four sides of the frame 17 are fixedly connected to the cylinder 2 33, the piston end of the cylinder 2 33 is fixedly connected to one side of the finger cylinder 44, a fixed rod 45 is fixedly connected to one side of the upper end face of the base 1, and threaded rods 2 46 are rotatably provided at both ends of the fixed rod 45, the threaded rod 2 46 is threadedly connected to the frame 17, the upper end of the fixed rod 45 is fixedly connected to a motor 9 47, and the output end of the motor 9 47 is fixedly connected to one end of the threaded rod 2 46.

[0033] Both sides of the turntable 31 are slidably connected with clamping blocks 32, and two sides of the lower end of the turntable 31 are rotatably provided with two-way threaded rods 29, both sides of the two-way threaded rods 29 are threadedly connected to the clamping blocks 32, one side of the lower end of the turntable 31 is fixedly connected to a six-motor 30, and the output end of the six-motor 30 is fixedly connected to one end of the two-way threaded rod 29, and the middle part of the lower end surface of the lifting plate 16 is fixedly connected to a five-motor 27, and the output end of the five-motor 27 is fixedly connected to the bottom of the rotating plate 28.

[0034] Specifically, in the above embodiment, although the woven bag can be fixed on the discharge pipe 13 to receive the flour, since the woven bag is made of a flexible material, the woven bag may have many wrinkles. After the flour enters the woven bag, it is easy to cause uneven distribution in the woven bag due to the wrinkles, and the space inside the woven bag is difficult to be fully utilized, thereby affecting the bagging effect of the flour. The bag is then drawn up and the bag is in a straight line, so that the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line, and the bag is in a straight line This prevents the bag from being spilled due to careless operation or accidental touching when the bag is removed from the discharge pipe 13, thereby further facilitating subsequent operation on the bag.

[0035] In this embodiment, Figure 3 As shown, a cooling component is also provided on the support frame 2; The cooling component includes an air cooler 9 fixedly connected to one side of the upper end of the support frame 2. The air outlet end of the air cooler 9 is connected to a connecting pipe 10. One end of the connecting pipe 10 is connected to an annular pipe 2 42. The annular pipe 2 42 is fixedly connected to the grinding cylinder 3. A plurality of air outlet pipes 8 are provided on the annular pipe 42, and the ends of the air outlet pipes 8 extend to the inner cavity of the grinding cylinder 3.

[0036] Specifically, since the grinding roller 43 generates a large amount of heat due to friction during grinding, the temperature of the grinding roller 43 increases. This high-temperature environment will destroy the trace elements and nutrients in the wheat raw materials, thereby reducing the quality of the produced flour. Therefore, in order to avoid this situation, during the grinding process, the cold air can be evenly transported by the cold air blower 9 through the annular pipe 2 42 and the air outlet pipe 1 8 to the inner cavity of the grinding cylinder 3 to cool the grinding roller 43. In this way, the temperature of the flour during grinding is effectively reduced by cold grinding, thereby ensuring the quality stability of the flour.

[0037] Working principle: Place the woven bag for holding flour under the grinding cylinder 3, and the bag opening is sleeved on the discharge pipe 13. At this time, the steel wire rope 24 is in a straight state and is located on the left side of the discharge pipe 13. Then, the cylinder 12 drives the adjusting block 21 to move horizontally, so that the adjusting block 21 moves from the discharge pipe 13 to the right side of the discharge pipe 13. During the movement of the adjusting block 21, the bag opening of the woven bag will be restrained by the steel wire rope 24 and fit into the surface of the discharge pipe 13. At the same time, the motor 4 22 is used to drive the roller 23 to rotate and unwind the steel wire rope 24, so that the steel wire rope 24 is always kept taut. At this time, one side of the bag opening of the woven bag is pressed against the surface of the discharge pipe 13, and then the motor 3 19 is used to drive the bidirectional threaded rod. The first cylinder 20 rotates, causing the two cylinders 12 to approach each other, and the two ends of the wire rope 24 also approach each other until the wire rope 24 forms a U shape, and then the motor 21 drives the mounting plate 41 to rotate 180 degrees, so that the U-shaped wire rope 24 crosses, and then the motor 8 38 drives the gear 39 to rotate, so that the rack rod 37 slides on the mounting plate 41, and the pressure rod 40 moves laterally and approaches the angle of the intersection of the wire ropes 24, and pushes the intersection of the wire ropes 24 until the intersection of the wire ropes 24 fits the outer wall of the discharge pipe 13. At this time, the wire rope 24 is tightly fitted with the outer wall of the discharge pipe 13, and the woven bag mouth is tightened to the discharge pipe 13 by the wire rope 24. Then the wheat raw material is added The flour is fed into the grinding drum 3, and the wheat raw material is in the gap between the grinding roller 43 and the grinding drum 3. At the same time, the grinding roller 43 is driven to rotate by the motor 5, and the wheat raw material can be ground by the grinding roller 43. The ground flour falls into the woven bag through the discharge pipe 13 for bagging. During the whole material receiving process, since the bag opening of the woven bag is tightly fitted with the discharge pipe 13, the flour can be accurately dropped into the woven bag and will not overflow from the bag opening due to splashing. Similarly, the woven bag will not tilt to one side due to deformation, resulting in flour outflow. This ensures the smooth progress of subsequent operations such as packaging and transportation of flour, and also saves the process of workers holding the woven bag to maintain its stability, reducing the workers' labor. The bag is then loaded with the bag's outer surface, which in turn causes the bag to fall over and become overturned, which in turn causes the bag to become overturned and overturned.When the woven bag is fixed on the discharge pipe 13, the air pump 15 is used to transport gas to the connecting pipe 2 14. The gas is filled into the woven bag after passing through the annular pipe 1 25 and the outlet pipe 2 26. The wrinkles on the surface of the woven bag will be reduced due to the filling of the gas. After the gas is filled, the woven bag will have a more regular shape. At this time, according to the height of the bottom edge of the woven bag, the motor 9 47 can be used to drive the threaded rod 2 46 to rotate, so that the frame 17 rises, so that the clamping end of the finger cylinder 44 is flush with the bottom edge of the woven bag, and then the cylinder 2 33 is used to drive the finger cylinder 44 to the bottom edge of the woven bag. The bag is then stretched with the cooperation of the four finger cylinders 44. When the flour enters the bag, the bag is always kept in a stretched state, thereby avoiding the uneven distribution of the flour in the bag due to wrinkles after the flour enters the bag, and the difficulty in fully utilizing the space inside the bag, thereby ensuring the bagging effect of the flour. Moreover, when the bag is filled with a sufficient amount of flour and the bag opening is removed from the discharge pipe 13, the bag opening is in an open state, which is easy to Flour may overflow from the mouth of the woven bag due to careless operation or accidental touch. Therefore, in order to avoid this situation, before removing the woven bag from the discharge pipe 13, the two-way threaded rod 29 can be driven by the motor 6 30 to rotate, so that the two clamping blocks 32 are close to each other to clamp the woven bag. At the same time, the motor 5 27 is used to drive the turntable 31 to rotate, so that the woven bag rotates. Since the mouth of the woven bag is fixed, the mouth of the woven bag will be tightened when the woven bag body rotates. At this time, the woven bag is removed from the discharge pipe 13. Since the mouth of the woven bag is tightened, Therefore, flour is less likely to overflow from the opening of the woven bag, preventing the woven bag opening from being easily spilled due to careless operation or accidental touching when the woven bag opening is removed from the discharge pipe 13. This further facilitates subsequent handling of the woven bag. During the grinding process, the cold air blower 9 can be used to evenly deliver cold air through the annular pipe 2 42 and the outlet pipe 1 8 to the inner cavity of the grinding cylinder 3, thereby cooling the grinding roller 43. This cold grinding method effectively reduces the temperature of the flour during grinding and ensures the stability of the flour quality.
