Description

Technical Field

[0001] The present invention relates to the technical field of conveying systems, and particularly to a safe conveying system for food processing. Background Art

[0002] With the development of the times and the progress of industry, automated equipment has been widely used in various industries. The food processing industry is no exception. In the food processing industry, the conveying system is like the blood vessels of a person, continuously conveying raw materials to each workshop and each process, and conveying the processed finished products to the designated location for storage, so as to ensure the orderly progress of production.

[0003] In food production, the safety of conveying is also an essential part to be considered. For example, in the process of producing flour products such as bread and noodles, it is necessary to convey the raw material, that is, flour. During the process of conveying flour, the flour is likely to disperse into the air. When the concentration of flour in the air reaches a certain level, if it encounters an open flame, it is prone to dust explosion, which is very dangerous. In order to ensure the safety during the production process of foods using flour as a raw material, currently, a dust-free feeding system for flour can be used to convey flour. For example, the Chinese utility model patent with the application number: CN201820271182.X is for dust-free feeding. It uses an air compressor unit to drive the flour to move inside the pipeline by airflow, avoiding the dispersion of flour into the external air and the risk of flour contacting an open flame, effectively ensuring the safety during the flour conveying process.

[0004] However, most existing manufacturers generally buy bagged flour during food production. Although the dust-free feeding system has greatly solved the problem of flour dispersion into the air during flour conveying, bagged flour needs to be unpacked and poured into the feeding port of the dust-free feeding system. During this operation step, there will still be a problem of flour dispersion into the air. Moreover, in order to ensure that the flour inside the bag can be poured into the feeding port as much as possible, workers will shake the bag, which will also cause the flour to further disperse into the air, increasing the dust concentration in the air and thus prone to safety accidents of dust explosion.

[0005] Although a protective cover is generally equipped at the feeding port, the protective cover is generally closed after the flour is poured into the feeding port, so the problem of flour dispersion into the air during the feeding process has not been solved.

[0006] Therefore, a safe conveying system for food processing is proposed. Summary of the Invention

[0007] The purpose of the present invention is to provide a safe conveying system for food processing. By first placing a whole bag of flour at the feeding port and covering it with a dust-proof cover, and then cutting open the plastic bag of the bagged flour to allow the flour to enter the interior of the feeding port, the problem of flour escaping during feeding at the feeding port of the dust-free feeding system described in the above background technology is solved.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A safe conveying system for food processing includes a feeding platform, a feeding port, a feeding pipe, an air compressor unit, and a discharging pipe. A plurality of supporting feet for fixing the feeding platform are fixed to the bottom of the feeding platform. The feeding port is opened in the middle of the feeding platform for flour feeding. The feeding pipe is communicated with the feeding port. One end of the feeding pipe away from the feeding port is connected to the discharging pipe. The air compressor unit is installed between the feeding pipe and the discharging pipe for conveying the flour in the direction of the discharging pipe. A clamping assembly for clamping the bagged flour is arranged on the feeding platform. An installation column is fixedly installed on the feeding platform. A dust-proof cover for covering the clamping assembly and the feeding port is slidably installed on the installation column. A tray is horizontally slidably installed at the feeding port. The tray is aligned with the feeding port and is used to support the bottom of the bagged flour. A blade is fixedly installed on one side of the top of the tray. A pull handle is fixedly installed at one end of the tray away from the blade. When the tray slides in the direction where the pull handle is located, the feeding port is opened and the blade cuts through the bottom of the bagged flour along the sliding direction of the tray.

[0010] The bagged flour is placed on the tray, and the clamping assembly is used to clamp the bagged flour to prevent the bagged flour from falling into the interior of the feeding port after the feeding port is opened. The clamping assembly can be a robotic arm or other devices or mechanisms capable of clamping the bagged flour. The dust-proof cover can slide up and down along the installation column. When the dust-proof cover slides down, it can cooperate with the feeding platform to cover the feeding port, the bagged flour, and the clamping assembly together, avoiding the flour from escaping into the air. Subsequently, the pull handle is pulled to make the tray move horizontally in the direction of the pull handle. The tray opens the feeding port, and the blade on the pull handle cuts through the bottom of the flour bag from the bottom of the bagged flour, allowing the flour inside the flour bag to fall into the feeding port from the cut opening. The air compressor assembly then sucks the flour at the feeding port into the feeding pipe and conveys the flour in the direction of the discharging pipe.

[0011] Since the dust-proof cover covers the bagged flour and then cuts open the flour bag, the flour is isolated by the dust-proof cover after the flour bag is cut open, avoiding the flour from escaping into the air outside the dust-proof cover and preventing the flour from coming into contact with an open flame and causing a dust explosion accident, thereby ensuring the safety during flour conveying.

[0012] Moreover, the opening of the flour bag is located below the flour bag and is directly opposite the feeding port. The airflow at the feeding port continuously sucks the flour into the feeding pipe, which improves the feeding speed and can also avoid the situation where the flour is lifted again after falling, reducing the dispersion of flour inside the dust cover and further reducing the situation where flour escapes into the air when the dust cover is opened.

[0013] Preferably, the grasping and clamping assembly includes a plurality of first support rods fixedly installed on one side of the feeding port. The plurality of first support rods are vertically fixed on the feeding platform, and the plurality of first support rods are evenly spaced along the edge of the feeding port. On the upper side of each first support rod, a first insertion rod is horizontally fixedly installed in the direction towards the feeding port. One end of the insertion rod towards the feeding port is provided with a first pointed cone portion. A plurality of sliding grooves corresponding to the plurality of first support rods are also formed on the feeding platform. The sliding grooves are all located on the side of the feeding port opposite to the first support rods. A second support rod is vertically slidably installed inside each sliding groove. A second insertion rod is horizontally fixed on the upper side of the second support rod. The second insertion rod is arranged in the direction towards the first insertion rod. One end of the second insertion rod towards the first insertion rod is provided with a second pointed cone portion. A connecting rod is arranged between the plurality of second support rods, and the connecting rod is used to fixedly connect the plurality of second support rods together. A driving assembly for driving the second support rod to move towards the first support rod is also provided on the feeding platform. Among them, the driving assembly can be an electric cylinder, a cylinder, or a device or mechanism capable of driving an object to move horizontally.

[0014] The driving assembly drives the second support rod to move horizontally towards the first support rod. The pointed cone portions on the first insertion rod and the second insertion rod pierce the side wall of the flour bag, and the flour bag is hung on the first insertion rod and the second insertion rod, realizing the grasping and clamping operation of the bagged flour, and avoiding the flour bag falling into the feeding port during the feeding process and causing blockage to the feeding port.

[0015] The reason for grasping and clamping the flour bag by piercing the side wall of the flour bag is that after the bottom of the flour bag is cut by the blade, the flour inside the flour bag will continuously flow out of the bottom opening of the flour bag. Without the support of the flour, the flour bag will become shriveled. If the flour bag is clamped by a robotic arm, a manipulator, etc., as the flour leaks from the inside of the flour bag, the grasping and clamping of the flour bag by the robotic arm and the manipulator will fail, and the flour bag is likely to fall into the feeding port. Although the pressure detection method can be used to make the robotic arm and the manipulator change the clamping degree as the flour inside the flour bag leaks, so as to avoid the flour bag falling into the feeding port, this will lead to a significant increase in the control cost and is not conducive to the saving of production costs.

[0016] However, by adopting the method of piercing the side wall of the flour bag, it is not necessary to consider the clamping force on the bagged flour and it can also avoid the situation where the flour bag falls into the feeding port, effectively saving the production and control costs of the equipment.

[0017] Preferably, the driving assembly includes an arc-shaped guiding portion provided at the top of each second rod. A guiding ramp corresponding to the guiding portion is also provided on the dust cover. A first spring is horizontally arranged inside the sliding groove. The first spring is used to keep pushing the second rod away from the first rod. When the dust cover moves downward, the guiding ramp presses the guiding portion and drives the second rod to slide toward the first rod.

[0018] The guiding ramp on the dust cover drives the clamping assembly to clamp the bagged flour. Compared with driving the clamping assembly to clamp the bagged flour by means of a motor, a push rod, etc., the production cost of the equipment is saved. Moreover, driving the clamping assembly to move by the action of the dust cover can also improve the synchronization of the clamping assembly and the dust cover, ensuring that the clamping assembly can clamp the bagged flour when the dust cover completely covers the bagged flour, which not only saves the control cost of the clamping assembly but also ensures the operation stability of the equipment.

[0019] Preferably, round rods are fixedly installed on both the left and right sides of the tray. Second springs are wound around the round rods. The second springs are used to pull the tray toward the blade and align the tray with the feed port. A locking reed is fixedly installed obliquely on the side of the feed port away from the blade. The locking reed faces the direction of the blade, and the locking reed slopes downward from the feeding platform toward the feed port. One end of the locking reed facing the direction of the blade is bent downward to form a hook portion. The hook portion is used to hook the edge of the tray when the tray slides toward the pull handle and reaches the extreme position.

[0020] When the bagged flour is placed on the tray, the weight of the bagged flour presses the locking reed, and the locking reed is pressed downward toward the tray. When an operator pulls the tray to slide toward the pull handle and the end of the tray away from the pull handle crosses the hook portion, the second spring is compressed under force. And the locking reed bends downward and deforms under the gravity of the bagged flour, and the hook portion will hook the end edge of the tray to prevent the tray from resetting under the elastic force of the second spring. As the flour inside the flour bag continuously flows downward from the break cut by the blade, the quality of the flour bag also continuously decreases. When the hook portion can no longer pull the edge of the tray, the second spring will push the tray to move away from the pull handle. The edge of the tray gives an upward component force to the hook portion, and the locking reed is pushed upward to reset, and the tray also resets under the action of the second spring.

[0021] An automatic unlocking device is set up by utilizing the weight of the bagged flour and the mutual cooperation of the locking reed and the hook portion. When pulling the tray to open the feed port, the tray is automatically locked. When the flour feeding is completed, the automatic reset of the tray reminds the operator, facilitating the operator to feed the flour again.

[0022] Preferably, a plurality of through slots are provided on the top of the support plate, the plurality of through slots are evenly distributed on the support plate, and the through slots are not aligned with the locking spring in the axial direction of the round rod.

[0023] When the pallet is reset, the flour inside the flour bag may not completely flow out from the hole, and some of it may remain inside the flour bag. At this time, the flour inside the flour bag will fall onto the top surface of the pallet. When the dust cover is opened, the flour on the top surface of the pallet needs to be cleaned manually, which is easy to escape into the air and cause the concentration of flour in the air to increase. In addition, the accumulation of flour on the top surface of the pallet can easily affect the smoothness of the pallet's sliding.

[0024] After multiple slots are set, the flour that falls on the top of the pallet can slide down to the feed port through the slots, preventing the flour from accumulating on the top of the pallet. Since the air compressor continuously draws the flour field at the feed port to the discharge pipe through the airflow, the airflow can also clean the flour that falls on the pallet, preventing the flour from escaping into the air after the dust cover is opened. Even if multiple slots are set, the pallet will not lose its support for the bagged flour.

[0025] The purpose of not aligning the through groove with the locking spring in the axial direction of the round rod is to avoid the locking spring from getting stuck in the through groove and causing interference when the support plate slides toward the handle, thereby avoiding the support plate from getting stuck and ensuring the stability of the equipment during operation.

[0026] Preferably, two paddles are arranged on the support plate, and the paddles are both made of elastic metal sheets, and the two paddles are symmetrically arranged on the support plate with respect to the blade.

[0027] When the second spring drives the support plate to return to its original position, the paddles continuously scrape the bottom of the flour bag and vibrate the bottom of the flour bag, so that the residual flour inside the flour bag can be shaken off from the opening cut by the blade as much as possible. The two paddles are symmetrical about the blade, so that the flour bag can be vibrated more evenly from both sides of the opening.

[0028] Preferably, a wavy vibration part is provided on the paddle. The wavy vibration part helps to increase the vibration frequency of the paddle when the paddle scrapes the bottom of the bag of flour, thereby further increasing the shaking frequency of the flour bag, helping to shake out the flour inside the flour bag from the opening cut by the blade as much as possible, and further reducing the residual flour inside the flour bag.

[0029] Preferably, a plurality of blocks are fixedly installed at the bottom of the dust cover corresponding to the plurality of slide grooves, and when the dust cover moves downward and closes the feed port, the plurality of blocks are respectively inserted into the plurality of slide grooves and prevent the second support rod from moving in a direction away from the first support rod.

[0030] When the dust cover squeezes and pushes the second rod towards the first rod, the first spring is compressed under force. As a result, the first spring will exert a thrust on the second rod in the direction away from the first rod, and under the action of the guiding part, the second rod will exert an upward component force on the dust cover. At this time, in order to ensure the clamping stability of the bagged flour and the sealing performance of the dust cover for the feeding port, it is necessary to manually keep pressing the dust cover downwards, or place a heavy object on the top of the dust cover to prevent the second rod from lifting the dust cover. After the clamping block is provided, only by pressing the dust cover downwards and making the clamping block snap into the inside of the chute can the situation that the second rod lifts the dust cover upwards be avoided, improving the convenience during the operation of the equipment. When it is necessary to push open the dust cover, only an upward force needs to be applied to the dust cover manually.

[0031] Preferably, the dust cover is made of a transparent material. The material for making the dust cover can be transparent plastic, transparent glass, or other transparent materials. The dust cover is set to be transparent mainly to facilitate the workers to observe the remaining amount of flour at the feeding port and the remaining amount of flour inside the bagged flour, so as to facilitate timely replenishment after the flour at the feeding port is conveyed. This helps to ensure the continuity of the flour transportation during food production and processing and the efficiency of food production.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] 1. A safety conveying system for food processing designed by the present invention first covers the bagged flour with a dust cover, and grabs and clamps the bagged flour inside the dust cover through a clamping component to prevent the bagged flour from falling into the feeding port. Subsequently, the pallet is pulled, and the bottom of the bagged flour is cut open inside the dust cover by the blade on the pallet, preventing the flour from escaping into the air outside the dust cover during flour feeding, thereby avoiding the occurrence of dust explosion and further ensuring the safety during flour feeding.

[0034] 2. A safety conveying system for food processing designed by the present invention grabs and clamps the flour by the form that the clamping component pierces the side wall of the flour bag through the first inserting rod and the second inserting rod. When the flour gradually flows out of the flour bag, it can firmly hold the flour bag, avoiding the situation that the clamping component cannot hold the bagged flour due to the change in the shape of the bagged flour, and preventing the flour bag from falling into the feeding port and causing blockage of the feeding port, further ensuring the stable operation of the equipment.

[0035] 3. A safe conveying system for food processing designed by the present invention is also provided with a paddle on the pallet, so that the paddle can move the bottom of the flour bag when the pallet is reset, so that the flour remaining in the flour bag can flow out more completely from the break at the bottom of the flour bag, avoiding excessive flour remaining in the flour bag and requiring subsequent manual cleaning, thereby improving the efficiency of the flour conveying system.

Detailed implementation manners

[0048] Please refer to Figures 1 to 11 , the present invention provides a safe conveying system for food processing, and the technical solution is as follows:

[0049] A safe conveying system for food processing, referring to Figure 1 , includes a feeding platform 1, a feeding port 2, a feeding pipe 3, an air compressor unit 4 and a discharging pipe 5. A plurality of supporting feet 6 for fixing the feeding platform 1 are fixed at the bottom of the feeding platform 1. The feeding port 2 is opened in the middle of the feeding platform 1 for flour feeding. The feeding pipe 3 is communicated with the feeding port 2. One end of the feeding pipe away from the feeding port 2 is connected with the discharging pipe 5. The air compressor unit 4 is installed between the feeding pipe 3 and the discharging pipe 5 for conveying the flour in the direction of the discharging pipe 5.

[0050] Referring to Figure 1 and Figure 2 , an installation column 7 is fixedly installed on the feeding platform 1. A dust-proof cover 8 for covering the gripper assembly and the feeding port 2 is slidably installed on the installation column 7. The dust-proof cover 8 of the dust-proof cover 8 is made of transparent plastic material. An inclined guiding slope 21 is further arranged on one side of the dust-proof cover 8 away from the installation column 7.

[0051] Referring to Figures 1 to 5 , a pallet 9 is horizontally slidably installed at the feeding port 2. The pallet 9 is aligned with the feeding port 2 and is used for supporting the bottom of the bagged flour. A blade 10 is fixedly installed on one side of the top of the pallet 9. A pull handle 11 is fixedly installed at one end of the pallet 9 away from the blade 10. Round rods 23 are fixedly installed on both the left and right sides of the pallet 9. A second spring 24 is wound around each round rod 23. The second spring 24 is used for pulling the pallet 9 in the direction of the blade 10 and making the pallet 9 aligned with the feeding port 2. A locking spring piece 25 is fixedly installed obliquely on the side of the feeding port 2 away from the blade 10. The locking spring piece 25 faces the direction of the blade 10, and the locking spring piece slopes downward from the feeding platform 1 towards the feeding port 2. One end of the locking spring piece 25 facing the direction of the blade 10 is bent downward to form a hook portion 26. The hook portion 26 is used for hooking the edge of the pallet 9 when the pallet 9 slides in the direction of the pull handle 11 and moves to the limit position.

[0052] Referring to Figure 3 and Figure 11 , a plurality of through slots 27 are further opened on the top of the pallet 9. The plurality of through slots 27 are evenly distributed on the pallet 9, and the through slots 27 are not aligned with the locking spring piece 25 in the axial direction of the round rod 23.

[0053] Referring to Figure 2 , Figure 5 and Figure 11, two paddles 28 are arranged on the pallet 9. The paddles 28 are both made of elastic metal sheets, and the two paddles 28 are symmetrically arranged on the pallet 9 with respect to the blade 10. A wavy vibration part 29 is also arranged on the paddle 28

[0054] Reference Figures 1 to 6 And Figure 10 , a gripper assembly for clamping the bagged flour is also arranged on the feeding platform 1. The gripper assembly includes three first support rods 12 fixedly installed on one side of the feeding port 2 close to the mounting column 7. The three first support rods 12 are vertically fixed on the feeding platform 1, and the three first support rods 12 are evenly spaced along the edge of the feeding port 2. A first insertion rod 13 is horizontally fixedly installed on the upper side of each first support rod 12 in the direction towards the feeding port 2. A first pointed cone part 14 is arranged at one end of the insertion rod towards the feeding port 2. Three sliding grooves 15 corresponding to the three first support rods 12 are also formed on the feeding platform 1. The sliding grooves 15 are all located on one side of the feeding port 2 opposite to the first support rods 12. A second support rod 16 is vertically slidably installed inside each sliding groove 15. A first spring 22 is horizontally arranged inside each sliding groove 15. The first spring 22 is used to keep pushing the second support rod 16 in the direction away from the first support rod 12. An arc-shaped guiding part 20 corresponding to the guiding slope 21 is arranged on one side of the top of each second support rod 16 away from the first support rod 12. A second insertion rod 17 is horizontally fixed on the upper side of the second support rod 16. The second insertion rod 17 is arranged in the direction towards the first insertion rod 13. A second pointed cone part 18 is arranged at one end of the second insertion rod 17 towards the first insertion rod 13. A connecting rod 19 is arranged between the three second support rods 16. The connecting rod 19 is used to fixedly connect the three second support rods 16 together.

[0055] Reference Figure 1 , three clamping blocks 30 are also installed at the bottom of the dust cover 8. The three clamping blocks 30 correspond to the three sliding grooves 15 in the vertical direction one by one.

[0056] Before use, the second spring 24 aligns the pallet 9 with the feeding port 2 under the action of its own elastic force. During use, first pull up the dust cover 8 vertically along the mounting column 7, and then place the bagged flour on the pallet 9 at the feeding port 2. At this time, the air pressure component sucks air and makes the air flow from the direction of the feeding port 2 along the feeding pipe 3 towards the discharging pipe 5.

[0057] Reference Figures 1 to 4 And Figure 10, when the bagged flour is placed on the pallet 9, the bagged flour presses down on the locking spring piece 25 under its own gravity. However, at this time, there is the pallet 9 supporting below the locking spring piece 25, so the locking spring piece 25 cannot continue to bend downward and deform. Subsequently, the dust-proof cover 8 is pulled downward along the mounting post 7. When the dust-proof cover 8 moves downward, the guiding slope 21 on the dust-proof cover 8 will press against the guiding part 20 on the second support rod 16. Under the extrusion of the guiding part 20 and the guiding slope 21, the dust-proof cover 8 will give the second support rod 16 a horizontal component force and make the second support rod 16 move horizontally in the direction of the first support rod 12, and the first spring 22 is compressed. When the second support rod 16 moves in the direction of the first support rod 12, it will press against the bagged flour and push the bagged flour in the direction of the first support rod 12. Finally, the second pointed cone part 18 on the second support rod 16 and the first pointed cone part 14 on the first support rod 12 respectively pierce the flour bag from the left and right sides of the bagged flour. The first insertion rod 13 and the second insertion rod 17 are inserted into the interior of the flour bag. When the dust-proof cover 8 moves downward to the limit position, the bottom of the dust-proof cover 8 fits against the upper surface of the feeding platform 1, and the dust-proof cover 8 covers the bagged flour, the feeding port 2, the first support rod 12, and the second support rod 16. At this time, the three clamping blocks 30 at the bottom of the dust-proof cover 8 are respectively clamped into the three sliding grooves 15. The clamping blocks 30 prevent the second support rod 16 from resetting under the push of the first spring 22 and avoid the dust-proof cover 8 from opening upward.

[0058] Reference Figure 1 , Figure 7 , Figures 8 to 10 , then the staff pulls the pull handle 11, and moves the pallet 9 horizontally in the direction of the pull handle 11. The blade 10 provided at the end of the pallet 9 away from the pull handle 11 moves together with the pallet 9, and the blade 10 cuts the flour bag at the bottom of the bagged flour during the movement. At this time, although the bottom of the bagged flour gradually loses support due to the gradual movement of the pallet 9, the flour inside the flour bag also continuously flows out from the break, and the weight of the bagged flour also continuously decreases. Therefore, even if the supporting force of the pallet 9 on the bagged flour becomes smaller, the flour will not fall into the feeding port 2. And because the flour bag is pierced by the first insertion rod 13 and the second insertion rod 17, the flour bag will also hang on the first insertion rod 13 and the second insertion rod 17, and the flour bag will not fall into the feeding port 2.

[0059] Reference Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 11, when the pallet 9 moves in the direction of the pull handle 11, the second spring 24 is compressed. The flap 28 also moves horizontally together with the blade 10 from the bottom of the bagged flour. At this time, since the bagged flour is still filled with flour inside, the flap 28 is squeezed and bent by the bottom of the bagged flour. When the end of the pallet 9 far from the pull handle 11 crosses the hook portion 26 on the locking spring piece 25, the locking spring piece 25 loses the support of the pallet 9, and the locking spring piece 25 will be further bent downward by the weight of the bagged flour. At this time, the pull handle 11 is released, and under the action of the second spring 24, the pallet 9 is horizontally pushed and reset in the direction away from the pull handle 11. Since the hook portion 26 is bent downward, it hooks the edge of the end of the pallet 9 far from the pull handle 11, and the pallet 9 cannot be reset.

[0060] Reference Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 11 , as the flour continuously flows downward from the break of the flour bag, the weight of the bagged flour continuously decreases, and the downward pressure on the locking spring piece 25 continuously decreases. When the locking spring piece 25 is no longer under the pressure of the bagged flour, the locking spring piece 25 resets upward under the action of its own elastic force, and the hook portion 26 no longer hooks the edge of the pallet 9. The pallet 9 moves horizontally in the direction away from the pull handle 11 under the elastic force of the second spring 24 to reset. During the reset process of the pallet 9, since the squeezing force of the bagged flour on the flap 28 also decreases after the flour continuously flows out from the break, the flap 28 resets upward under its own elastic force. The vibrating portion 29 on the flap 28 continuously scrapes the bottom of the flour bag during the reset process following the pallet 9, causing the flour bag to vibrate, so that the remaining flour inside the flour bag can more completely flow into the feed port 2 from the break.

[0061] When the pallet is completely reset, reference Figure 1 and Figure 11 , due to multiple through slots provided on the pallet, the air pressure assembly can still suck the flour out of the flour bag from the break through the air flow at this time, and make the flour be sucked into the inside of the feed port, and then continue to transport the flour to the discharge pipe. When the pallet is reset, the employee can observe the situation inside the dust-proof cover through the transparent dust-proof cover. When the flour inside the dust-proof cover is transported as much as possible towards the discharge pipe and there is no longer any raised flour inside the dust-proof cover, the dust-proof cover can be pulled upward. After the dust-proof cover is pulled upward, since there is no clamping block to limit the second rod, the second rod automatically resets under the action of the first spring. Subsequently, after the staff removes the flour bag from the first insertion rod and the second insertion rod, repeating the above steps can continue the flour feeding operation.

[0062] The above has described in detail a specific embodiment of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiment. For those skilled in the art, without departing from the principles and ideas of the present invention, various changes, modifications, substitutions, and variations made to these embodiments should still fall within the protection scope of the present invention.
