Description

Technical Field

[0001] This invention relates to a flour loading system, specifically a finished product loading system for flour mills and its operating method, belonging to the field of application technology for finished flour loading systems. Background Technology

[0002] The process of transferring bagged flour into trucks for loading is usually done manually. However, due to the large output of flour mills, manual loading is time-consuming and labor-intensive. Therefore, a flour loading system is needed to assist workers in transferring bagged finished flour into trucks to improve loading speed.

[0003] However, the current flour mill's finished product loading system has significant shortcomings. The current system cannot adjust its height during loading, making it inconvenient for workers to transfer flour into the loading system. Furthermore, the current system cannot raise the flour level during loading, preventing it from matching the height of the truck bed and hindering the loading process. Finally, the current system cannot transfer flour to different locations within the truck bed, making it difficult for workers to stack the flour inside the truck. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a finished product loading system for flour mills and its operating method.

[0005] A finished product loading system for a flour mill includes a displacement mechanism and a lifting mechanism. The lifting mechanism is located above the displacement mechanism. A tilting mechanism is installed on one side of the lifting mechanism, and a transmission mechanism is installed on the side of the tilting mechanism away from the lifting mechanism. The tilting mechanism includes a mounting frame and a connecting plate. The connecting plate is located above the mounting frame. An electric cylinder is installed inside the mounting frame, and a pull rod passes through one end of the electric cylinder. A connecting rod is installed between the mounting frame and the connecting plate. The bottom of the connecting plate is fixedly connected to the connecting rod. The electric cylinder controls the lifting and lowering of the pull rod, and in conjunction with the rotation of the connecting rod, drives the connecting plate to rotate, so that the connecting plate can be tilted, thereby driving the transmission mechanism to tilt and change the direction of the transmission mechanism. Thus, after the finished flour is loaded onto the transmission mechanism, it can be tilted to the same height as the truck.

[0006] The conveying mechanism includes a fixed frame and two anti-slip columns. The two anti-slip columns are welded to the bottom sides of the fixed frame. A conveyor belt is installed inside the fixed frame. Rotary rollers are connected to both ends of the fixed frame via rotating shafts. The two ends of the conveyor belt are respectively fitted onto the outer surfaces of the two rotating rollers. When the rotating rollers rotate, they drive the conveyor belt to rotate, thereby moving the finished flour and allowing the finished flour to automatically approach the truck, making loading more convenient. At the same time, the anti-slip columns not only support the finished flour at the bottom, making it easier to fix the finished flour inside the conveying mechanism, but also prevent the flour from slipping when the loading system rotates the flour.

[0007] Preferably, the displacement mechanism includes a base and two slide rails, both of which are located above the base. A slide frame is installed on the slide rail, and the slide frame has an inverted "L" shaped cross-section. A slider is installed on the inner side wall of the top of the slide frame. The slide rail has an "I" shaped cross-section. The slider is adapted to the slide rail and slides along the slide rail, thereby enabling the slide frame to slide back and forth on the base.

[0008] Preferably, mounting plates are welded to both sides of the upper surface of the base. Two slide rails are fixed above the two mounting plates. A motor is installed at one end of one of the mounting plates. A lead screw is connected to the motor via a rotating shaft. A nut is installed on the inner wall of the slide frame near the lead screw. The nut is threadedly engaged with the lead screw. The motor drives the rotating shaft to rotate the lead screw. The rotating lead screw engages with the nut, thereby moving one of the slide frames and providing continuous power to the slide frame, making the slide frame move more smoothly. Universal casters are installed at the four corners of the bottom of the base. When the loading personnel push the loading system, the universal casters rotate, thus saving manpower when the loading system moves.

[0009] Preferably, the lifting mechanism includes a sliding plate, a second mounting plate, and a lifting frame. The second mounting plate is located above the sliding plate, and the lifting frame is located below one side of the second mounting plate. The two ends of the sliding plate are welded to the upper surfaces of the two sliding frames respectively. A second motor is installed on the upper surface of the second mounting plate. A second lead screw is connected to the second motor via a rotating shaft. A second nut is provided in the middle of one side of the lifting frame. The second nut is threadedly engaged with the second lead screw. The second motor drives the rotating shaft to rotate the second lead screw. The rotating second lead screw is threadedly engaged with the second nut, thereby driving the lifting frame to rise and fall.

[0010] Preferably, slide rods are fixed on both sides of the lead screw, and sliders are provided on both sides of the nut. The slide rods pass through the sliders. When the lifting frame is raised or lowered, the sliders slide along the slide rods, thereby fixing the lifting direction of the lifting frame and making the lifting frame more stable during lifting. The middle of the slider is provided with an opening, and several balls are installed inside the opening. The balls slide along the two slide rods respectively, and the balls can reduce friction when the slider slides along the slide rods.

[0011] Preferably, the mounting frame has an inverted "L" shaped cross-section. The electric cylinder is hinged to the bottom of the mounting frame. A connecting block is welded to the top of the pull rod. A flipping frame is provided at the top of the pull rod. The flipping frame has a "U" shaped cross-section. A bearing is installed at the top of the connecting block. The bottom of the flipping frame passes through the connecting block, and the bottom of the flipping frame is rotatably fitted in the middle of the bearing at the top of the connecting block. The two ends of the flipping frame away from the connecting block are welded to the upper end face of the connecting plate. When the electric cylinder pulls the pull rod to extend or retract, the connecting plate can be pulled through the connecting block and the flipping frame.

[0012] Preferably, bearing seats are fixed to both sides of the top of the mounting frame with nuts. The two ends of the connecting rod are located inside the two bearing seats respectively, and the two ends of the connecting rod are rotatably fitted in the middle of the two bearing seats. This not only allows the two ends of the connecting rod to be kept stable through the two bearing seats, but also allows the connecting rod to rotate smoothly in the middle of the two bearing seats. The lifting frame has an "L" shaped cross-section, and the bottom of the mounting frame is welded to the inside of the lifting frame. The lifting frame can drive the mounting frame to rise and fall, thereby improving the flexibility of the mounting frame during operation.

[0013] Preferably, two bottom posts are welded to one end of the connecting plate, and a limit block is welded to the bottom of the bottom posts. The limit block is located on the upper surface of the mounting frame. After the connecting plate is flipped downward to a certain angle, the bottom posts and the limit block can abut against the upper surface of the mounting frame, thereby preventing the connecting plate from flipping excessively and causing the transmission mechanism to collide with the mounting frame and be damaged.

[0014] Preferably, a motor is installed on the fixed frame. The motor is connected to one end of one of the rotating rollers via a rotating shaft. The motor drives the rotating roller to rotate, which in turn drives the other rotating roller to rotate, thereby driving the conveyor belt to rotate and providing power support for the conveyor belt. Side plates are welded on both sides of the fixed frame, and both side plates are welded to the connecting plate. Several raised strips are welded at equal intervals on the outer surface of the conveyor belt, so that the raised strips can increase the friction between the finished flour bag and the conveyor belt.

[0015] Preferably, the operating method of the finished product loading system for a flour mill specifically includes the following steps:

[0016] Step 1: The loading personnel push the loading system, and the casters rotate, moving the loading system to the front of the truck to be loaded. Motor 1 drives the shaft to rotate the lead screw, which engages with the nut, thus moving one of the sliding frames. This, in turn, moves the slider along the slide rail, causing the slide to move left and right. The sliding frame, through the lifting frame, mounting frame, connecting plate, and side plate, moves the fixed frame and anti-slip post left and right. Simultaneously, Motor 2 drives the shaft to rotate the lead screw, which engages with the nut, causing the slider to slide along the slide rail, raising and lowering the lifting frame. The raised frame, through the mounting frame, connecting plate, and side plate, moves the fixed frame and anti-slip post up and down. Through this coordination, the fixed frame and anti-slip post can move smoothly left and right and rise and fall. The left and right moving fixed frame and anti-slip post can quickly move to the side of the finished flour pile to be loaded, and with the lifting of the fixed frame and anti-slip post, they can be raised and lowered to a height suitable for workers to load the flour.

[0017] Step Two: The worker loads the finished flour onto the anti-slip posts, close to the fixed frame. The pull rod lifts and lowers the connecting block and the tilting frame, causing the connecting plate to tilt. The tilted connecting plate then tilts through the side plate, keeping the fixed frame parallel to the ground. This raises the finished flour and brings it closer to the truck. Then, the motor drives the shaft to rotate the screw, which engages with the nut. The slider slides along the slide rod, raising and lowering the lifting frame. The lifting frame, through the mounting frame, connecting plate, and side plate, raises and lowers the fixed frame and anti-slip posts. This allows for precise adjustment of the height of the fixed frame and anti-slip posts, ensuring they are higher than the bottom of the truck bed.

[0018] Step 3: The fixing frame and anti-slip post move left and right, inserting the finished flour and one end of the fixing frame into the car. Then, the motor drives the rotating roller to rotate, which in turn drives the conveyor belt to rotate, transferring the finished flour from inside the loading system to the car for loading.

[0019] The beneficial effects of this invention are:

[0020] (1) The electric cylinder controls the lifting and lowering of the pull rod in this invention, which drives the connecting plate to flip. The flipped connecting plate then flips through the side plate, keeping the fixed frame parallel to the ground, thereby raising the finished flour and bringing it closer to the truck. In addition, the second motor drives the rotating shaft to rotate the second screw, which in turn drives the lifting frame to lift. The lifting frame lifts through the mounting frame, connecting plate, and side plate, which in turn drives the fixed frame and anti-slip column to lift. The height of the fixed frame and anti-slip column can be precisely adjusted again, so that the loading system can adapt to trucks of different models and heights, thereby expanding the scope of application of the loading system. It is highly applicable and helps to promote its application.

[0021] (2) In this invention, the first motor drives the rotating shaft to rotate the first lead screw, which in turn drives the sliding plate to move left and right through the sliding frame. The sliding plate moves left and right through the lifting frame, mounting frame, connecting plate, and side plate, which in turn drives the fixed frame and anti-slip column to move left and right. Combined with the second motor driving the rotating shaft to rotate the second lead screw, the lifting frame is driven to rise and fall. The rising and falling lifting frame drives the fixed frame and anti-slip column to rise and fall through the mounting frame, connecting plate, and side plate. Through the above coordination, the fixed frame and anti-slip column can move left and right and rise and fall smoothly. On the one hand, the left and right moving fixed frame and anti-slip column can quickly move to the side of the finished flour pile that needs to be loaded, shortening the distance between the loading system and the flour pile to be loaded. The lifting mechanism of the fixed frame and anti-slip columns allows them to be raised to a suitable height for workers to load flour, facilitating the handling and transfer of finished flour. This enables the finished flour to be quickly transferred into the loading system. Furthermore, after the fixed frame is rotated to be parallel to the ground, the lifting mechanism of the fixed frame and anti-slip columns can raise both the fixed frame and the finished flour again. Combined with the left and right movement of the fixed frame and anti-slip columns, one end of the fixed frame and the finished flour can be inserted into the truck, making it easier for workers inside the truck to lift and stack the finished flour, thus facilitating loading. Moreover, when using this loading system, workers do not need to raise the finished flour during loading, making the loading operation simple, time-saving, and labor-saving.

[0022] (3) The electric cylinder controls the lifting and lowering of the pull rod in this invention, which, together with the connecting rod, drives the connecting plate to rotate and flip. The flipped connecting plate, through the side plate, flips, keeping the fixed frame parallel to the ground, thereby raising the finished flour and bringing it closer to the trolley. Combined with the motor's three-drive system, the rotating roller rotates, which in turn drives the conveyor belt to rotate, transferring the finished flour from inside the loading system to inside the trolley. Combined with the left and right movement of the fixed frame and anti-slip column, the finished flour is transferred to different positions inside the trolley, making it easier for workers inside the trolley to stack it. This makes the loading system more efficient, the loading speed of the finished flour faster, and helps to improve the flour mill's output speed. Attached Figure Description

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1-9As shown, a finished product loading system for a flour mill includes a displacement mechanism 1 and a lifting mechanism 2. The lifting mechanism 2 is located above the displacement mechanism 1. A tilting mechanism 3 is installed on one side of the lifting mechanism 2, and a transmission mechanism 4 is installed on the side of the tilting mechanism 3 away from the lifting mechanism 2. The tilting mechanism 3 includes a mounting frame 301 and a connecting plate 302. The connecting plate 302 is located above the mounting frame 301. An electric cylinder 305 is installed inside the mounting frame 301. A pull rod 306 passes through one end of the electric cylinder 305. A connecting rod 304 is installed between the mounting frame 301 and the connecting plate 302. The bottom of the connecting plate 302 is fixedly connected to the connecting rod 304. The electric cylinder 305 controls the lifting and lowering of the pull rod 306, and in conjunction with the rotation of the connecting rod 304, it drives the connecting plate 302 to rotate, so that the connecting plate 302 can be tilted, thereby driving the transmission mechanism 4 to tilt, thus changing the direction of the transmission mechanism 4. After the finished flour is loaded onto the transmission mechanism 4, it can be tilted to the same height as the truck, which facilitates loading and saves time and effort.

[0036] The conveying mechanism 4 includes a fixed frame 401 and two anti-slip posts 405. The two anti-slip posts 405 are welded to the bottom sides of the fixed frame 401. A conveyor belt 402 is installed inside the fixed frame 401. Rotary rollers 403 are connected to both ends of the fixed frame 401 through rotating shafts. The two ends of the conveyor belt 402 are respectively sleeved on the outer surface of the two rotary rollers 403. When the rotary rollers 403 rotate, they drive the conveyor belt 402 to rotate, thereby moving the finished flour and allowing the finished flour to automatically approach the truck, making loading more convenient. At the same time, the anti-slip posts 405 not only support the finished flour at the bottom, making it easier to fix the finished flour inside the conveying mechanism 4, but also prevent the flour from slipping when the loading system rotates the flour, effectively speeding up the loading speed and improving the working efficiency of the loading system.

[0037] In an optional embodiment of the present invention, the displacement mechanism 1 includes a base 101 and two slide rails 106. Both slide rails 106 are located above the base 101. A sliding frame 105 is installed on the slide rails 106. The cross-section of the sliding frame 105 is an inverted "L" shape. A slider 108 is installed on the inner sidewall of the top of the sliding frame 105. The cross-section of the slide rail 106 is an "I" shape. The slider 108 is adapted to the slide rail 106 and slides along the slide rail 106, thereby enabling the sliding frame 105 to slide back and forth on the base 101, improving the flexibility of the sliding frame 105.

[0038] In one optional embodiment of the present invention, mounting plates 102 are welded to both sides of the upper surface of the base 101. Two slide rails 106 are respectively fixed above the two mounting plates 102. A motor 103 is mounted on one end of one of the mounting plates 102. A lead screw 104 is connected to the motor 103 via a rotating shaft. A nut 107 is installed on the inner side wall of the slide frame 105 near the lead screw 104. The nut 107 is threadedly engaged with the lead screw 104. The motor 103 drives the rotating shaft to move... The lead screw 104 rotates, and the rotating lead screw 104 engages with the nut 107, thereby driving one of the slide frames 105 to move, thus providing continuous power to the slide frame 105, making the slide frame 105 move more smoothly when moving back and forth, thereby improving the stability of the transmission of the loading system. Universal wheels 109 are installed at the four corners of the bottom of the base 101. When the loading personnel push the loading system, the universal wheels 109 rotate, thereby saving manpower when the loading system moves and making the loading system move more quickly.

[0039] In an optional embodiment of the present invention, the lifting mechanism 2 includes a sliding plate 201, a second mounting plate 202, and a lifting frame 203. The second mounting plate 202 is located above the sliding plate 201, and the lifting frame 203 is located below one side of the second mounting plate 202. The two ends of the sliding plate 201 are respectively welded to the upper end surfaces of two sliding frames 105. A second motor 206 is installed on the upper end surface of the second mounting plate 202. A second lead screw 207 is connected to the second motor 206 through a rotating shaft. A second nut 205 is provided in the middle of one side of the lifting frame 203. The second nut 205 is threadedly engaged with the second lead screw 207. The second motor 206 drives the rotating shaft to drive the second lead screw 207 to rotate. The rotating second lead screw 207 is threadedly engaged with the second nut 205, thereby driving the lifting frame 203 to rise and fall, improving the flexibility of the lifting frame 203 during operation.

[0040] In an optional embodiment of the present invention, slide rods 208 are fixed on both sides of the lead screw 207, and sliders 204 are provided on both sides of the nut 205. The slide rods 208 pass through the sliders 204. When the lifting frame 203 is raised or lowered, the sliders 204 slide along the slide rods 208, thereby fixing the raising and lowering direction of the lifting frame 203 and making the lifting frame 203 more stable during raising and lowering. The middle part of the sliders 204 has an opening, and several balls are installed inside the opening. The balls slide along the two slide rods 208 respectively. When the sliders 204 slide along the slide rods 208, the balls can reduce friction, thereby reducing the wear rate between the sliders 204 and the slide rods 208, and thus extending the service life of the loading system.

[0041] In one optional embodiment of the present invention, the mounting bracket 301 has an inverted "L" shaped cross-section. The electric cylinder 305 is hinged to the bottom of the mounting bracket 301. A connecting block 307 is welded to the top of the pull rod 306. A flipping frame 308 is provided on the top of the pull rod 306. The flipping frame 308 has a "U" shaped cross-section. A bearing is installed on the top of the connecting block 307. The bottom of the flipping frame 308 passes through the connecting block 307, and the bottom of the flipping frame 308 is rotatably fitted in the middle of the bearing on the top of the connecting block 307. The two ends of the flipping frame 308 away from the connecting block 307 are welded to the upper end face of the connecting plate 302. When the electric cylinder 305 pulls the pull rod 306 to extend or retract, the connecting plate 302 can be pulled through the connecting block 307 and the flipping frame 308, making the connecting plate 302 more stable when flipping.

[0042] In an optional embodiment of the present invention, bearing seats 303 are fixed to both sides of the top of the mounting frame 301 by nuts. The two ends of the connecting rod 304 are respectively located inside the two bearing seats 303, and the two ends of the connecting rod 304 are rotatably engaged in the middle of the two bearing seats 303. This not only allows the two ends of the connecting rod 304 to be kept stable by the two bearing seats 303, but also allows the connecting rod 304 to rotate smoothly in the middle of the two bearing seats 303. The lifting frame 203 has an "L" shaped cross-section, and the bottom of the mounting frame 301 is welded to the inside of the lifting frame 203. The lifting frame 203 can drive the mounting frame 301 to rise and fall, thereby improving the flexibility of the mounting frame 301 during operation.

[0043] In one optional embodiment of the present invention, two bottom posts 309 are welded to the bottom of one end of the connecting plate 302, and a limiting block 310 is welded to the bottom of the bottom posts 309. The limiting block 310 is located on the upper end face of the mounting frame 301. After the connecting plate 302 is flipped downward to a certain angle, the bottom posts 309 and the limiting block 310 can abut against the upper end face of the mounting frame 301, thereby preventing the connecting plate 302 from over-flipping and causing the transmission mechanism 4 to collide with the mounting frame 301 and cause damage, thus extending the service life of the loading system.

[0044] In an optional embodiment of the present invention, a motor 404 is installed on the fixed frame 401. The motor 404 is connected to one end of one of the rotating rollers 403 via a rotating shaft. The motor 404 drives the rotating roller 403 to rotate, which in turn drives the conveyor belt 402 to rotate, providing power support for the conveyor belt 402. Side plates 407 are welded to both sides of the fixed frame 401. Both side plates 407 are welded to the connecting plate 302. Several protrusions 406 are welded at equal intervals on the outer surface of the conveyor belt 402. The protrusions 406 can increase the friction between the finished flour bag and the conveyor belt 402, preventing the finished flour from falling off the loading system.

[0045] In operation, the loading personnel first push the loading system, causing the casters 109 to rotate and move the system to the truck to be loaded. Motor 103 drives the shaft, which in turn rotates the lead screw 104. The rotating lead screw 104 engages with the nut 107, which in turn moves one of the sliding frames 105. This, in turn, moves the slider 108 along the slide rail 106, causing the slide frame 105 to move left and right. The sliding frame 105 then moves the slide plate 201 left and right. The moving slide plate 201, through the lifting frame 203, mounting bracket 301, connecting plate 302, and side plate 407, moves the fixing frame 401 and anti-slip post 405 left and right. Simultaneously, motor 206 drives the shaft, which rotates the lead screw 207. The rotating lead screw 207 engages with the nut 205, which in turn moves the slider 208. 204 slides along the slide bar 208, driving the lifting frame 203 to rise and fall. The rising and falling lifting frame 203 drives the fixed frame 401 and anti-slip column 405 to rise and fall through the mounting frame 301, connecting plate 302 and side plate 407. Through the above cooperation, the fixed frame 401 and anti-slip column 405 can move smoothly left and right and rise and fall. The left and right moving fixed frame 401 and anti-slip column 405 can quickly move to the side of the finished flour pile to be loaded, shortening the distance between the loading system and the flour pile to be loaded. In addition, with the lifting and falling of the fixed frame 401 and anti-slip column 405, the fixed frame 401 and anti-slip column 405 can be raised and lowered to a height suitable for workers to load flour, thereby facilitating workers to move and transfer finished flour, and thus facilitating the rapid transfer of finished flour into the loading system.

[0046] Then, the worker loads the finished flour onto the anti-slip post 405, close to the fixed frame 401. The pull rod 306 raises and lowers the connecting block 307 and the tilting frame 308, causing the connecting plate 302 to tilt. The tilted connecting plate 302 then tilts via the side plate 407, keeping the fixed frame 401 parallel to the ground, thereby raising the finished flour and bringing it closer to the trolley. Then, the motor 206 drives the shaft to rotate the lead screw 207. The rotating lead screw 207 engages with the nut 205, which in turn engages with the slider 2... 04 Slide along the slide bar 208 to drive the lifting frame 203 to rise and fall. The rising and falling lifting frame 203 drives the fixed frame 401 and anti-slip column 405 to rise and fall through the mounting frame 301, connecting plate 302 and side plate 407. The height of the fixed frame 401 and anti-slip column 405 can be precisely adjusted again so that the fixed frame 401 and anti-slip column 405 are higher than the bottom of the car body. This allows the loading system to adapt to car bodies of different models and heights, thereby expanding the scope of application of the loading system. It has strong applicability and helps to promote its application.

[0047] Finally, the fixing frame 401 and anti-slip column 405 move left and right, inserting the finished flour and one end of the fixing frame 401 into the interior of the trolley. Then, the motor 404 drives the rotating roller 403 to rotate, which in turn drives the conveyor belt 402 to rotate, transferring the finished flour from inside the loading system to inside the trolley for loading. This system is convenient for loading, as workers do not need to lift the finished flour during loading. The loading operation is simple, time-saving, and labor-saving. Furthermore, the left and right movement of the fixing frame 401 and anti-slip column 405 allows the finished flour to be transferred to different positions inside the trolley, making it convenient for workers inside the trolley to lift and stack the finished flour. This makes the loading system highly efficient, and the loading speed of the finished flour is faster, which helps to improve the output speed of the flour mill.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.

2. The working method of a finished product loading system for a flour mill according to claim 1, characterized in that: The method specifically includes the following steps: Step 1: The loading personnel push the loading system, and the casters (109) rotate, moving the loading system to the front of the truck to be loaded. Motor 1 (103) drives the shaft to rotate the lead screw 1 (104). The rotating lead screw 1 (104) engages with the nut 1 (107) threadedly, thereby moving one of the sliding frames (105). This, in turn, moves the slider 1 (108) along the slide rail (106), which in turn moves the slide plate (201) left and right through the sliding frame (105). The left and right moving slide plate (201) moves the fixed frame (401) and anti-slip post (405) left and right through the lifting frame (203), mounting frame (301), connecting plate (302), and side plate (407). This, combined with the motor 2 (206) driving the shaft to rotate the lead screw 2 (207), causes the fixed frame (401) and anti-slip post (405) to move left and right. The rotating lead screw (207) is threadedly engaged with the nut (205), and the slider (204) slides along the slide bar (208), driving the lifting frame (203) to rise and fall. The lifting frame (203) drives the fixed frame (401) and anti-slip column (405) to rise and fall through the mounting frame (301), connecting plate (302) and side plate (407). Through the above coordination, the fixed frame (401) and anti-slip column (405) can move smoothly left and right and rise and fall. The left and right moving fixed frame (401) and anti-slip column (405) can quickly move to the side of the finished flour pile that needs to be loaded. In conjunction with the rising and falling of the fixed frame (401) and anti-slip column (405), the fixed frame (401) and anti-slip column (405) can be raised and lowered to a height suitable for workers to load flour. Step Two: The worker loads the finished flour onto the anti-slip column (405), close to the fixed frame (401). The pull rod (306) raises and lowers the connecting block (307) and the tilting frame (308), causing the connecting plate (302) to tilt. The tilted connecting plate (302) then tilts through the side plate (407), keeping the fixed frame (401) parallel to the ground, thereby raising the finished flour and bringing it closer to the trolley. Then, the motor (206) drives the rotating shaft to rotate the screw (207). The screw rod (207) and nut (205) are threaded together, and the slider (204) slides along the slide rod (208) to drive the lifting frame (203) to rise and fall. The lifting frame (203) drives the fixed frame (401) and anti-slip column (405) to rise and fall through the mounting frame (301), connecting plate (302) and side plate (407). The height of the fixed frame (401) and anti-slip column (405) can be precisely adjusted again so that the fixed frame (401) and anti-slip column (405) are higher than the bottom of the car body. Step 3: The fixed frame (401) and anti-slip column (405) move left and right, inserting the finished flour and one end of the fixed frame (401) into the car. Then, the motor (404) drives the rotating roller (403) to rotate, and the other rotating roller (403) rotates, which in turn drives the conveyor belt (402) to rotate, so that the finished flour is transferred from the loading system to the car and loaded into the car.
