Description

Technical Field

[0001] This invention relates to the field of flour feeding equipment technology, specifically a flour processing feeding device. Background Technology

[0002] Flour is a powdery substance made from wheat. Based on its protein content, it can be classified into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. It is widely used in food processing, catering, and other fields. In the industrial production and processing of flour, it needs to go through standardized processes such as cleaning and impurity removal, grinding and milling, sieving and grading, and post-processing and packaging. Among these, the post-processing and packaging process directly affects the storage stability, transportation safety, and product appearance quality of flour, and is one of the key processes in the flour production chain.

[0003] In the post-processing and packaging process, flour processing and feeding equipment is the core equipment for transferring flour from storage or conveying to packaging containers. Currently, the industry generally uses a combination structure of screw conveyor and funnel hopper to complete the flour feeding and collection operation. The conventional operation process of this type of equipment is as follows: the screw conveyor concentrates and continuously transports the ground and sieved flour into the funnel hopper. The conical structure of the funnel hopper guides the flour to converge at the bottom outlet, and then it falls precisely from the outlet into receiving containers such as packaging bags and material barrels, completing the preparatory work for quantitative feeding. However, due to the influence of the shape of the funnel hopper, the flour will pile up in a hill-like shape when it is fed into the receiving container, which can easily cause flour to overflow outside the receiving container opening.

[0018] 2. This flour processing feeding device uses a strut to drive the mixing blades to adjust the spacing inside the regulating trough. This causes the mixing area of ​​the mixing blades to change continuously as they rotate. Similarly, the struts repeatedly rise and fall as they rotate, causing the area of ​​the struts that mix the flour to change continuously. This further improves the range and uniformity of flour mixing, reduces the probability of flour clumping and bridging, and improves the smoothness of flour feeding. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1:

[0031] Please see Figure 1-9 A flour processing feeding device includes a screw conveyor, which includes a screw conveyor body, an operating platform 1, and a second connecting member 5. A support column 11 is fixed to the top of the operating platform 1, a support frame 12 is fixed to the surface of the support column 11, an outer frame 2 is fixed to the surface of the support frame 12, a feeding funnel 21 is fixed to the surface of the outer frame 2, an internal cavity 201 is opened inside the outer frame 2, a ventilation pipe 23 is fixed to the top of the outer frame 2, a first spring 24 is fixed to the inner wall of the internal cavity 201, a first connecting member 25 is fixed to the surface of the first spring 24, a heat-conducting rod 26 is fixed to the surface of the first connecting member 25, and the heat-conducting rod 26 is slidably and sealingly connected to the feeding funnel 21.

[0032] A mounting box 3 is fixed to the top of the support column 11. The mounting box 3 has a first mounting chamber 31 and a second mounting chamber 32. The fan blade shaft 33 is rotatably connected inside the second mounting chamber 32. A first motor 34 is fixed to the surface of the mounting box 3. The output shaft of the first motor 34 passes through the mounting box 3 and is fixed to the rotating shaft of the fan blade shaft 33. An electric heating tube 35 is fixed to the inner wall of the second mounting chamber 32 below the fan blade shaft 33. The second mounting chamber 32 is connected to the internal cavity 201 through the ventilation pipe 23.

[0033] A sealing door 211 is hinged to the surface of the feeding funnel 21. A top cover 22 is fixed to the top of the feeding funnel 21. A feed pipe 221 is fixed to one side of the top of the top cover 22. A second motor 4 is fixed inside the first installation chamber 31. The output shaft of the second motor 4 passes through the installation box 3 and the top cover 22. The output shaft of the second motor 4 extends into the inside of the feeding funnel 21. A first sealing pipe 41 is fixed to the output shaft of the second motor 4. A crossbeam 42 is fixed to the bottom of the first sealing pipe 41. Adjustment grooves 43 are opened on both sides inside the crossbeam 42. A stirring blade 44 is slidably connected inside the adjustment groove 43. A second spring 45 is fixed to one side of the stirring blade 44. One end of the second spring 45 is fixed to the crossbeam 42.

[0034] An L-shaped frame 6 is fixed to the bottom of the support frame 12 near the feeding hopper 21. A dustproof chamber 61 is opened inside the horizontal part of the L-shaped frame 6. An electromagnet 62 is fixed to the inner wall of the dustproof chamber 61 away from the feeding hopper 21. An elastic rope 63 is fixed to the surface of the electromagnet 62. A sealing plate 64 is fixed to one end of the elastic rope 63. The sealing plate 64 is slidably connected to the dustproof chamber 61 and slidably sealed to the bottom of the feeding hopper 21.

[0035] In the specific operation process, the outlet of the external screw conveyor is first connected to the feed pipe 221 through a pipe, and then the flour is conveyed into the inside of the discharge hopper 21. Then, the controller starts the first motor 34 and the electric heating tube 35. The electric heating tube 35 heats the air in the second installation chamber 32. The first motor 34 drives the fan blade shaft 33 to rotate, so that the heated air in the second installation chamber 32 is blown into the interior of the ventilation pipe 23. The hot air enters the interior of the internal cavity 201 through the ventilation pipe 23. Then, the hot air heats the outer frame 2, the first connecting piece 25 and the heat-conducting rod 26.

[0036] Heat is transferred to the feeding hopper 21 through the outer frame 2, so that the feeding hopper 21 is heated, and the flour inside the feeding hopper 21 is heated, thereby improving the dryness of the flour inside the feeding hopper 21, reducing the moisture content of the flour, and thus reducing the probability of the flour clumping and clogging the feeding hopper 21 due to moisture absorption, thereby improving the smoothness of feeding from the feeding hopper 21.

[0037] Then, the heat is further transferred directly to the feeding hopper 21 through the heat-conducting rod 26, reaching deeper layers of flour and further expanding the range of flour drying by heat.

[0038] Furthermore, once the flour in the feeding hopper 21 reaches its upper limit, the controller starts the second motor 4, which drives the first sealing tube 41 to rotate, which in turn drives the crossbeam 42 to rotate, which in turn drives the stirring blade 44 to rotate. During the rotation, the stirring blade 44 stirs the flour, thereby reducing the probability of flour clumping and bridging, and thus improving the smoothness of subsequent flour feeding.

[0039] Meanwhile, with the stirring of the stirring blade 44, flour from different areas can be continuously carried to the area around the heat-conducting rod 26, which further expands the drying range of the flour by the heat-conducting rod 26. Similarly, the stirring blade 44 can also continuously carry flour from different areas to the inner wall of the feeding funnel 21, which increases the uniformity of the flour drying on the inner wall of the feeding funnel 21, thereby reducing the probability of flour clumping and improving the smoothness of flour feeding.

[0040] When feeding is required, the controller de-energizes the electromagnet 62, causing it to generate magnetic force and attract the sealing plate 64. This causes the sealing plate 64 to retract into the dustproof chamber 61, opening the feeding port of the feeding funnel 21 and thus completing the smooth feeding of flour. After feeding is completed, the power supply to the electromagnet 62 is cut off, causing it to lose its attraction to the sealing plate 64. Under the reset action of the elastic rope 63, the sealing plate 64 is reset, sealing the feeding port of the feeding funnel 21.

[0041] It should be noted that all the equipment in this invention is controlled by a controller. The sealing door 211 is made of transparent acrylic sheet and can be used as a window to observe the flour feeding situation. When necessary, the sealing door 211 can be opened to maintain components such as the crossbeam 42 and the stirring blade 44.

[0042] Example 2:

[0043] A sliding groove 46 is provided on one side of the two stirring blades 44 facing each other. A second sealing tube 47 is fixed at the bottom of the crossbeam 42. A first sealing tube 41 is connected to the second sealing tube 47 through the crossbeam 42. A cylinder 48 is fixed inside the first sealing tube 41. The second sealing tube 47 is slidably sealed to the second connecting piece 5. The top of the second connecting piece 5 is fixed to the output shaft of the cylinder 48. A support rod 51 is fixed at the bottom of the second connecting piece 5. The two ends of the support rod 51 are slidably connected to the sliding groove 46.

[0044] Specifically, based on Embodiment 1, when the second motor 4 is started, the second motor 4 drives the first sealing tube 41 and the crossbeam 42 to rotate, that is, the crossbeam 42 drives the stirring blade 44 to rotate, that is, the second motor 4 drives the stirring blade 44 to rotate inside the feeding funnel 21. During this process, the controller starts the cylinder 48, causing the output shaft of the cylinder 48 to push out, so that the output shaft of the cylinder 48 drives the second connecting member 5 to extend outward from the inside of the second sealing tube 47. That is, the pushing out of the cylinder 48 drives the second connecting member 5 to descend along the vertical direction of the second sealing tube 47, and the return stroke of the cylinder 48 drives the second connecting member 5 to rise along the vertical direction of the second sealing tube 47.

[0045] Furthermore, since the second connecting piece 5 is fixed to the support rod 51, and the two ends of the support rod 51 are slidably connected to the sliding groove 46 respectively, when the second connecting piece 5 is descending, the second connecting piece 5 drives the support rod 51 to descend synchronously, so that the support rod 51 slides down along the sliding groove 46 from top to bottom. Since the distance between the two sliding grooves 46 gradually shortens from top to bottom, the support rod 51 gradually pushes the stirring blade 44 inside the adjusting groove 43 and slides towards both sides during the downward sliding process. That is, when the support rod 51 continues to descend, the two stirring blades 44 continue to move towards both sides of the crossbeam 42.

[0046] As the support rod 51 continues to rise, the two stirring blades 44 remain attached to both ends of the support rod 51 under the action of the second spring 45. That is, as the support rod 51 continues to rise, the two stirring blades 44 gradually close towards the direction of the second motor 4. Therefore, when the cylinder 48 repeatedly pushes out and returns, the cylinder 48 drives the second connecting piece 5 and the support rod 51 to repeatedly close and separate the stirring blades 44.

[0047] That is, after the second motor 4 and the cylinder 48 are started at the same time, the distance between the two stirring blades 44 is constantly changing, which in turn causes the area of ​​the stirring blades 44 stirring the flour in the feeding funnel 21 to change continuously, thereby improving the uniformity of flour stirring, further reducing the probability of flour clumping and bridging, and once again improving the smoothness of flour feeding.

[0048] Furthermore, when the stirring blade 44 rotates, its rotation trajectory contacts the heat-conducting rod 26. That is, when the stirring blade 44 is stirring the flour, it will periodically and briefly contact the heat-conducting rod 26, thereby squeezing the heat-conducting rod 26. Under the action of the first spring 24 and the first connecting member 25, the heat-conducting rod 26 slides repeatedly on the inner wall of the feeding funnel 21. During the repeated sliding of the heat-conducting rod 26, it plays a role in directly striking the flour, further reducing the probability of flour clumping. At the same time, the repeated sliding of the heat-conducting rod 26 can reduce the probability of flour being electrostatically adsorbed on the surface of the feeding funnel 21, further improving the smoothness of flour feeding.

[0049] While the heat-conducting rod 26 slides repeatedly, it drives the first connector 25 to move repeatedly inside the built-in cavity 201. During the movement of the first connector 25, the first connector 25 can repeatedly tap the outer wall of the feeding funnel 21, thereby shaking off the flour electrostatically adsorbed on the inner wall of the feeding funnel 21, thus reducing the probability of the feeding funnel 21 being blocked due to electrostatic adsorption of flour, and further improving the smoothness of flour feeding.

[0050] Furthermore, during the rotation of the first sealing tube 41 driven by the second motor 4, since the cylinder 48 is fixed inside the first sealing tube 41, when the first sealing tube 41 rotates, the cylinder 48 drives the second connecting piece 5 and the support rod 51 to rotate synchronously. While rotating, the support rod 51 is driven by the push-out and return stroke of the cylinder 48, and the support rod 51 is in a state of rotating while rising or falling. In this way, the flour at the center of the feeding funnel 21 is stirred by the support rod 51, which further improves the efficiency of stirring the flour, reduces the probability of flour clumping and bridging stroke, and improves the smoothness of flour feeding.

[0051] It should be noted that the two ends of the support rod 51 are hemispherical, which ensures the smooth sliding of the support rod 51 in the sliding groove 46. At the same time, the bottom of the stirring blade 44 is not closed and is in an open state. Furthermore, with the two ends of the support rod 51 being hemispherical, flour will not accumulate inside the sliding groove 46, thus avoiding the waste of flour.

[0052] The maximum stroke of cylinder 48 is shown in the instruction manual. Figure 7 and Figure 8 As shown, after the cylinder 48 is pushed out to its maximum stroke, the stirring blade 44 moves to both sides to its maximum stroke, and the support rod 51 moves to the bottom of the sliding groove 46. After the stirring blade 44 reaches its maximum stroke, it contacts the heat-conducting rod 26. The spacing of the stirring blade 44 is adjustable, which means that the force of the stirring blade 44 pressing the heat-conducting rod 26 is adjustable.

[0053] Example 3:

[0054] The bottom of the second connector 5 is fixed with a screw 52, ​​and the surface of the screw 52 is threaded with an extension rod 53. Limiting grooves 7 are opened on both sides of the operating table 1. An insertion hole 71 is opened on the side of the operating table 1 near the feeding funnel 21. A locking block 72 is slidably connected inside the limiting groove 7. The two locking blocks 72 are fixedly connected by the placement table 73. A pin 74 is slidably connected inside the locking block 72. The diameter of the pin 74 is equal to the diameter of the insertion hole 71.

[0055] Specifically, based on Embodiment 1 and Embodiment 2, before feeding the flour, the pin 74 is first pulled out from the inside of the locking block 72, and then the height of the placement platform 73 is adjusted so that the placement platform 73 drives the locking block 72 to rise and fall inside the limiting groove 7. After the adjustment is completed, the pin 74 is passed through the locking block 72 and inserted into the inside of the insertion hole 71, thereby completing the fixation of the placement platform 73. After the container is placed on the top of the placement platform 73, the inlet of the container is located below the feeding port of the feeding funnel 21. Then, the electromagnet 62 is energized by the controller so that the electromagnet 62 attracts the sealing plate 64, thereby releasing the seal on the feeding port of the feeding funnel 21.

[0056] Furthermore, during the start-up of cylinder 48, support rod 51 drives screw 52 and extension rod 53 to move synchronously. That is, during the repeated descent and ascent of support rod 51, extension rod 53 repeatedly descends and ascends inside the feeding hopper 21. During the repeated descent and ascent of extension rod 53, it repeatedly passes through the feeding port of feeding hopper 21. Subsequently, the metal of the feeding port of feeding hopper 21 can be cleared through extension rod 53, reducing the probability of blockage and bridging at the feeding port of feeding hopper 21, thereby improving the smoothness of flour feeding.

[0057] Meanwhile, when the extension rod 53 moves repeatedly inside the discharge port of the discharge hopper 21, it can reduce the discharge flow rate of the discharge hopper 21, avoid bridging and agglomeration, and prevent the discharge speed from being too fast after breaking up. This reduces the occurrence of material rushing in the discharge hopper 21, thereby improving the accuracy of the discharge from the discharge hopper 21 and avoiding excessive material rushing, which could lead to errors in the weight of the flour output.

[0058] Furthermore, when the container receives flour below the discharge port of the feeding funnel 21, as the amount of flour discharged gradually increases, the height of the flour in the container gradually increases, and a hill-like shape is formed near the container opening. During the descent, the extension rod 53 extends into the container opening to press down the piled-up flour, achieving the effect of spreading the flour evenly. This makes the flour in the container tend to be horizontal, preventing flour from overflowing during subsequent flour collection and thus improving the integrity of flour collection.

[0059] It should be noted that when the sealing plate 64 is not released from the discharge port of the discharge funnel 21, that is, when the flour is not discharged, the cylinder 48 cannot reach the maximum stroke. Therefore, the support rod 51 cannot move to the bottom of the sliding groove 46, the spacing of the stirring blade 44 cannot reach the maximum stroke, and the stirring blade 44 cannot contact the heat-conducting rod 26. Therefore, the heat-conducting rod 26 cannot slide on the inner wall of the discharge funnel 21, and the first connecting piece 25 cannot strike the discharge funnel 21.

[0060] Only when the sealing plate 64 releases the seal on the discharge port of the discharge funnel 21, i.e. when flour is being discharged, can the spacing of the stirring blades 44 reach its maximum stroke, and the stirring blades 44 contact and press the heat-conducting rod 26, so that the first connecting member 25 can strike the inner wall of the discharge funnel 21. This prevents the inner wall of the discharge funnel 21 from being electrostatically attracted to flour. In other words, the first connecting member 25 can only strike the discharge funnel 21 when flour is being discharged, and there is no need to strike the discharge funnel 21 when no flour is being discharged.
