Description

Technical Field

[0001] This utility model relates to the field of flour processing technology, specifically to a flour grinding device that facilitates feeding. Background Technology

[0002] Flour, also known as wheat flour, is a powdery substance produced by milling wheat and is a common food ingredient. Flour processing requires grinding, making flour milling equipment an indispensable and important piece of equipment in flour production.

[0003] Application number CN202020627880.6 discloses a flour grinding device for easy diversion and feeding. It includes a collecting trough with its lower sidewall inclined at an angle equal to that of the feeding pipe. A feeding trough is welded to the upper end of the collecting trough, and its longitudinal section is an inverted isosceles trapezoid, facilitating feeding after grinding. A movable rod is included; rotation of the semi-circular gear causes the movable frame to slide the rod on the fixed box, resulting in elastic deformation of the return spring. The movable rod is slidably connected to a baffle, facilitating control of the baffle's back-and-forth rotation. A baffle is also included, forming a flipping structure inside the hopper, with the lower end of the hopper located inside the slot, facilitating control of the raw material feeding amount and diverting the feed, thus improving grinding efficiency. However, this design has shortcomings: the first drive motor lacks a heat dissipation mechanism, resulting in low heat dissipation efficiency; and the hopper cannot dry damp flour, limiting its application.

[0004] Therefore, we propose a flour grinding device that facilitates material feeding. Utility Model Content

[0005] The main objective of this invention is to provide a flour grinding device that facilitates material feeding. By incorporating a heat dissipation mechanism consisting of a tube, fan, air outlet, and heat dissipation channels, the fan draws in external cold air and precisely blows it onto the first motor through the air outlet. Simultaneously, hot air is promptly discharged through the heat dissipation channels, significantly improving the heat dissipation efficiency of the first motor. A heating jacket is attached to the inner wall of the hopper, and the heating resistance wire within the jacket heats and dries the raw materials in the hopper. Combined with the stirring action of the feeding rod driven by the second motor, the raw materials are heated evenly, ensuring effective drying and effectively solving the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A flour grinding device for easy feeding includes a housing, a mounting cover, a first motor, and a hopper. The hopper is fixedly inserted into the top of the housing. A heating sleeve is snapped into the inner wall of the hopper. A fastener is fitted onto the top of the hopper. The top of the heating sleeve is fixedly connected to the lower part of the inner wall of the fastener. A clamping plate for mounting a second motor is snapped into the center of the top of the fastener. A protective cover is provided on the outside of the second motor. The bottom end of the protective cover is fixedly connected to the upper surface of the clamping plate. The hopper also contains a rotating shaft and a feeding rod. The top of the rotating shaft is connected to the output shaft at the bottom of the second motor through a coupling.

[0008] The bottom of the housing has a centrally located, upward-protruding mounting cover. The mounting cover contains a mounting cavity for assembling the first motor. The lower part of the bottom of the housing has a heat dissipation channel communicating with the mounting cavity. The lower part of one side of the housing has a socket for installing a tube. One end of the tube passes through the socket and is vertically inserted into one side of the mounting cover. The mounting cover has an air outlet at the location of the tube. The tube contains an air inlet channel for installing a fan. The air inlet channel communicates with the air outlet. An air outlet cover is fastened to the inner wall of the mounting cavity near the air outlet.

[0009] By adopting the above technical solution, and by setting up a heat dissipation mechanism consisting of a tube, a fan, an air outlet shroud, and a heat dissipation channel, the fan introduces external cold air and blows it precisely onto the first motor through the air outlet, while the hot air is discharged in time through the heat dissipation channel. This greatly improves the heat dissipation efficiency of the first motor, ensures the stable operation of the first motor, extends its service life, realizes the drying function of damp flour, and reduces the limitations of use.

[0010] Specifically, the air outlet hood has an air outlet cavity that communicates with the air outlet. The air outlet hood is located on one side of the first motor, and the side of the air outlet hood near the first motor has multiple air outlet holes that are equidistantly arranged.

[0011] Specifically, the inner wall of the insertion tube is provided with an assembly groove for installing a fan at the center. The fan is fixedly engaged with the inner wall of the insertion tube and blows air towards the air outlet.

[0012] Specifically, an assembly plate is fixedly sleeved on the outer side of the end of the insertion tube away from the mounting cover. The assembly plate is fixedly connected to the lower part of one side of the box body by bolts. A protective net is snapped into the inner wall of the end of the insertion tube near the assembly plate. Both ends of the protective net have buckle grooves on their inner walls.

[0013] Specifically, the heating jacket is equipped with a heating resistance wire, the outer side of the heating jacket is in contact with the inner wall of the hopper, and the rotating shaft is located inside the heating jacket.

[0014] Specifically, the top of the hopper is provided with a slot that matches the card plate, a heat dissipation mesh is embedded on one side of the protective cover, and a feeding rod is vertically welded to both sides of the rotating shaft.

[0015] The beneficial effects of this utility model are as follows: The flour grinding device for easy feeding described in this utility model, through the heat dissipation mechanism composed of a tube, fan, air outlet, and heat dissipation channel, allows the fan to introduce external cold air and precisely blow it onto the first motor through the air outlet, while hot air is promptly discharged through the heat dissipation channel. This significantly improves the heat dissipation efficiency of the first motor, ensures its stable operation, extends its service life, and enables the drying function of damp flour, reducing its usage limitations. A heating jacket is attached to the inner wall of the hopper, and the heating resistance wire inside the jacket can heat and dry the raw materials in the hopper. Combined with the stirring action of the feeding rod driven by the second motor, this allows the raw materials to be dried. Uniform heating ensures effective drying, making the device suitable not only for drying flour but also for handling damp flour. The rotating feed rod inside the hopper effectively moves the raw materials downwards while stirring them, preventing accumulation and ensuring smooth feeding. Combined with the heating and drying function, this further ensures stable feeding and improves overall grinding efficiency. The device features a rational structural design, making installation and maintenance of each component convenient. For example, the insert is fixed to the housing via mounting plates and bolts, facilitating disassembly and maintenance. The protective net can be easily removed for cleaning via a clip. The heating jacket is securely connected to the hopper via fasteners, also facilitating subsequent replacement and maintenance, thus reducing the device's operating and maintenance costs.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As one embodiment of this utility model, such as Figures 1-4 As shown, the present invention discloses a flour processing grinding device for easy feeding, comprising a housing 1, a mounting cover 2, a first motor 5, and a hopper 11. The hopper 11 is fixedly inserted into the top of the housing 1. A heating sleeve 12 is snapped into the inner wall of the hopper 11. A fastener 13 is fitted onto the top of the hopper 11. The top of the heating sleeve 12 is fixedly connected to the lower part of the inner wall of the fastener 13. A clamping plate 20 for installing a second motor 21 is snapped into the center of the top of the fastener 13. A protective cover 22 is provided on the outside of the second motor 21. The bottom end of the protective cover 22 is fixedly connected to the upper end face of the clamping plate 20. The hopper 11 also contains a rotating shaft 18 and a feeding rod 19. The top end of the rotating shaft 18 is connected to the output shaft at the bottom of the second motor 21 through a coupling.

[0024] The bottom of the housing 1 has a centrally located, upwardly protruding mounting cover 2. The mounting cover 2 has a mounting cavity 3 for assembling the first motor 5. The bottom of the housing 1 has a heat dissipation channel 4 communicating with the mounting cavity 3. The bottom of one side of the housing 1 has a socket 7 for installing a tube 8. One end of the tube 8 passes through the socket 7 and is vertically inserted into one side of the mounting cover 2. The mounting cover 2 has an air outlet 15 located at the position of the tube 8. The tube 8 has an air intake channel 16 for installing a fan 10. The air intake channel 16 communicates with the air outlet 15. An air outlet cover 6 is fastened to the inner wall of the mounting cavity 3 near the air outlet 15.

[0025] During use, in the grinding process, the first motor 5 located in the mounting cavity 3 inside the mounting cover 2 provides power for grinding. To prevent the first motor 5 from overheating and affecting its operation, the fan 10 inside the insertion tube 8 is started. The fan 10 blows air towards the air outlet 15. The external air enters the air intake channel 16 after being filtered by the protective net 9, and then enters the air outlet cavity of the air outlet cover 6 through the air outlet 15. Finally, it is blown towards the first motor 5 through multiple equidistant air outlet holes 14 on the side of the air outlet cover 6 near the first motor 5 to dissipate heat. The hot air generated by the first motor 5 is discharged through the heat dissipation channel 4 at the bottom of the housing 1, which is connected to the mounting cavity 3, forming a good heat dissipation cycle.

[0026] The present invention also includes an air outlet cavity that communicates with the air outlet 15 inside the air outlet cover 6, the air outlet cover 6 being located on one side of the first motor 5, and the air outlet cover 6 having a plurality of equidistant air outlet holes 14 on the side near the first motor 5.

[0027] The present invention also includes an assembly groove for installing a fan 10 at the center of the inner wall of the insertion tube 8, wherein the fan 10 is fixedly engaged with the inner wall of the insertion tube 8 and the fan 10 blows air toward the air outlet 15.

[0028] The present invention also includes an assembly plate 23 fixedly sleeved on the outer side of the end of the insertion tube 8 away from the mounting cover 2. The assembly plate 23 is fixedly connected to the lower part of one side of the box body 1 by bolts. A protective net 9 is snapped into the inner wall of the end of the insertion tube 8 near the assembly plate 23. Both ends of the inner wall of the protective net 9 are provided with buckle grooves 24.

[0029] The present invention also includes a heating resistance wire 17 inside the heating sleeve 12, the outer side of the heating sleeve 12 being in contact with the inner wall of the hopper 11, and the rotating shaft 18 being located inside the heating sleeve 12.

[0030] The present invention also includes a slot at the top center of the hopper 11 that is compatible with the card plate 20, a heat dissipation mesh embedded on one side of the protective cover 22, and feeding rods 19 vertically welded on both sides of the rotating shaft 18.

[0031] In use, the flour raw material to be ground is put into the hopper 11. At this time, the heating resistance wire 17 inside the heating jacket 12 is activated. The outer side of the heating jacket 12 contacts the inner wall of the hopper 11, which can evenly heat the raw material in the hopper 11 to dry the damp flour. At the same time, the second motor 21 installed on the card plate 20 is activated. The protective cover 22 on the outside of the second motor 21 can protect it. The heat dissipation mesh on one side of the protective cover 22 can dissipate the heat generated by the second motor 21 in time. The output shaft at the bottom of the second motor 21 drives the rotating shaft 18 to rotate through the coupling. The feed rods 19 vertically welded on both sides of the rotating shaft 18 rotate together with the rotating shaft 18. The rotating feed rods 19 can not only stir the raw material to make it heat more evenly, but also assist the raw material to flow downward, which is convenient for subsequent grinding.

[0032] During the grinding process, the first motor 5 located in the mounting cavity 3 inside the mounting cover 2 provides power for grinding. To prevent the first motor 5 from overheating and affecting its operation, the fan 10 inside the insertion tube 8 is started. The fan 10 blows air towards the air outlet 15. The external air enters the air intake channel 16 after being filtered by the protective net 9, and then enters the air outlet cavity of the air outlet cover 6 through the air outlet 15. Finally, it is blown towards the first motor 5 through multiple equidistant air outlet holes 14 on the side of the air outlet cover 6 near the first motor 5 to dissipate heat. The hot air generated by the first motor 5 is discharged through the heat dissipation channel 4 at the bottom of the housing 1, which is connected to the mounting cavity 3, forming a good heat dissipation cycle.
