Description

Technical Field

[0001] This utility model relates to the field of flour production technology, and in particular to an alternating flour quantitative bagging machine. Background Technology

[0002] With the development of the food industry, flour, as an important food raw material, is undergoing continuous improvement in processing and packaging technology. However, traditional flour packaging equipment, due to technological limitations, often faces problems such as complex operation and low efficiency, which to some extent restricts the efficiency of the entire production line.

[0003] In modern flour processing technology, common packaging equipment includes simple gravity feeding systems and mechanical metering devices. These devices typically only support single-process operations and cannot meet the high efficiency and precision requirements of modern production lines. For example, some equipment requires a pause after completing one bag of flour, waiting for another bag to be placed at the outlet before resuming bagging, thus impacting bagging efficiency.

[0004] However, existing flour bagging equipment has a significant problem in practical operation: it cannot effectively achieve rapid and continuous quantitative bagging of flour. Especially on high-volume production lines, a single bagging device can hardly cope with the continuous bagging demand, resulting in limited efficiency of the entire production process. Utility Model Content

[0005] The purpose of this invention is to propose an alternating flour quantitative bagging machine to solve the problem that existing flour bagging equipment cannot achieve fast and continuous quantitative bagging of flour.

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

[0007] An alternating flour quantitative bagging machine includes a frame, a storage hopper, a switching mechanism, a quantitative hopper, and a bag clamping mechanism. Multiple horizontal beams are vertically arranged on the frame, and the quantitative hopper and bag clamping mechanism are respectively mounted on different horizontal beams. The storage hopper is installed at the top of the frame, and its bottom has two openings for flour discharge. The switching mechanism is installed at the openings to alternately open and close the two openings. The quantitative hopper is located at the bottom of the switching mechanism and is used to receive the flour from the storage hopper. The bag clamping mechanism is installed at the bottom of the quantitative hopper and is used to clamp flour bags and receive the flour from the quantitative hopper.

[0008] By adopting the above technical solution, rapid and continuous quantitative bagging of flour can be achieved, improving bagging efficiency and reducing bagging delays caused by waiting for flour bags.

[0009] Furthermore, a weighing sensor is provided between the crossbeam and the quantitative chamber, and there are two quantitative chambers, which are located at the bottom of the two openings respectively.

[0010] By adopting the above technical solutions, the quantitative control of flour can be improved, and the bagging accuracy can be enhanced.

[0011] Furthermore, the bottom of the quantitative hopper is provided with an arc-shaped discharge port, and a baffle for opening and closing the discharge port is rotatably provided on the side wall of the discharge port. The shape of the baffle is adapted to the discharge port. A first hydraulic cylinder is rotatably provided on the baffle and the quantitative hopper. The first hydraulic cylinder drives the baffle to open and close the discharge port.

[0012] By adopting the above technical solution, the discharge port can be opened and closed quickly, thus improving the bagging speed.

[0013] Furthermore, after the flour in the storage silo is discharged into the metering silo, it is then discharged from the outlet into the bag clamping mechanism. When one of the metering silos is discharging, the outlet of the other metering silo is blocked by a baffle.

[0014] By adopting the above technical solution, it can be ensured that the two quantitative silos work alternately, avoiding the chaos caused by the simultaneous discharge of flour.

[0015] Furthermore, the switching mechanism includes a switching plate that is slidably disposed at two openings, a second hydraulic cylinder that drives the switching plate to slide, a flow port of the same size as the openings being opened in the middle of the switching plate, and blocking portions on both sides of the flow port of the switching plate that block the openings.

[0016] By adopting the above technical solution, the switching plate can be quickly slid between the two openings, thereby improving the switching efficiency.

[0017] Furthermore, the size of the blocking portion is larger than the size of the flow opening, so as to block the opening.

[0018] By adopting the above technical solution, it can be ensured that the switching plate completely blocks the opening when not in operation, preventing flour leakage.

[0019] Furthermore, a stabilizing plate is installed on the side wall of the storage silo, a track is fixedly installed on the stabilizing plate, a slider that slides on the track is fixedly installed on the switching plate, and the second hydraulic cylinder is rotatably connected to the stabilizing plate.

[0020] By adopting the above technical solution, the stability of the switching plate during the sliding process can be ensured, and the bagging error caused by shaking can be reduced.

[0021] Furthermore, the bag clamping mechanism includes a flow guide chamber mounted on other crossbeams, two clamps rotatably mounted on the flow guide chamber, and a third hydraulic cylinder that drives the clamps to rotate. The two clamps are arranged opposite to each other. A cylinder for fitting flour bags is installed at the bottom of the flow guide chamber. The clamps and the cylinder abut against each other to clamp the flour bags. The cylinder body and piston rod of the third hydraulic cylinder are rotatably connected to the two clamps respectively.

[0022] By adopting the above technical solutions, the stable clamping of flour bags can be ensured, improving the accuracy and efficiency of bagging.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The alternating flour quantitative bagging machine of this utility model achieves rapid and continuous quantitative bagging of flour by setting an alternating opening and closing switching mechanism and a quantitative bin, thereby improving bagging efficiency; by setting a weighing sensor and a baffle, the accuracy and speed of bagging are improved; by setting a hydraulic cylinder to control the baffle and switching plate, the stability and reliability of the bagging process are enhanced; and by setting a bag clamping mechanism, the clamping stability of flour bags is improved, and errors in the bagging process are reduced.

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] This embodiment relates to an alternating flour quantitative bagging machine, the overall structure of which is as follows: Figure 1 and Figure 3 As shown, it includes a frame 1, a storage bin 2, a switching mechanism 3, a metering bin 4, and a bag clamping mechanism 5.

[0044] The frame 1 has multiple vertically arranged crossbeams 6. The metering bin 4 and the bag clamping mechanism 5 are arranged and installed on different crossbeams 6. The storage bin 2 is installed on the top of the frame 1. The bottom of the storage bin 2 has two openings 7 for flour discharge. The switching mechanism 3 is installed at the openings 7 and alternately opens and closes the two openings 7. The metering bin 4 is located at the bottom of the switching mechanism 3. The flour in the storage bin 2 is discharged into the metering bin 4. The bag clamping mechanism 5 is installed at the bottom of the metering bin 4. The bag clamping mechanism 5 clamps the flour bag and discharges the flour in the metering bin 4 into the flour bag.

[0045] Based on the above overall introduction, this embodiment presents an exemplary structure of an alternating flour quantitative bagging machine, such as... Figure 2 As shown, a weighing sensor 8 is installed between the crossbeam 6 and the quantitative bin 4. There are two quantitative bins 4, located at the bottom of the two openings 7 respectively. It should be noted that the weighing sensor 8 is a common sensor in the prior art. Its function is to measure the weight of the flour falling. When the set weight is reached, the switching mechanism 3 switches the opening 7 to discharge the flour, thereby realizing alternating discharge and improving bagging efficiency.

[0046] As a preferred option, it remains as follows Figure 2 As shown, in this embodiment, the bottom of the quantitative silo 4 is provided with a discharge port 9, which is arc-shaped. A baffle 10 for opening and closing the discharge port 9 is rotatably provided on the side wall of the quantitative silo 4. The shape of the baffle 10 matches that of the discharge port 9. A first hydraulic cylinder 11 is rotatably provided on the baffle 10 and the quantitative silo 4. The first hydraulic cylinder 11 drives the baffle 10 to open and close the discharge port 9. Specifically, after the flour in the storage silo 2 is discharged into the quantitative silo 4, it is discharged from the discharge port 9 into the bag clamping mechanism 5. When one quantitative silo 4 is discharging, the discharge port 9 of the other quantitative silo 4 is blocked by the baffle 10. That is to say, the baffles 10 of the two quantitative silos 4 are opened alternately. The shape of the baffle 10 and the discharge port 9 are the same. The purpose is to ensure that the discharge port 9 can be sealed when blocked by the baffle 10. The cylinder body of the first hydraulic cylinder 11 is rotatably connected to the side wall of the quantitative silo 4, and the piston rod of the first hydraulic cylinder 11 is rotatably connected to the baffle 10. This arrangement enables the baffle 10 to be driven to rotate.

[0047] As a preferred implementation method, such as Figure 3As shown, the switching mechanism 3 of this embodiment includes a switching plate 301 that is slidably disposed at two openings 7, and a second hydraulic cylinder 302 that drives the switching plate 301 to slide. The middle part of the switching plate 301 is provided with a flow port 303 of the same size as the opening 7, and the switching plate 301 is provided with blocking parts on both sides of the flow port 303 to block the opening 7. It should be noted that the cylinder body of the second hydraulic cylinder 302 is rotatably connected to the storage bin 2, and the piston rod of the second hydraulic cylinder 302 is rotatably connected to the side of the switching plate 301. This arrangement enables the second hydraulic cylinder 302 to drive the switching plate 301 to slide at the two openings 7. The size of the flow port 303 is the same as the size of the opening 7. When the switching plate 301 slides, the flow port 303 overlaps with the two openings 7 in turn. When the flow port 303 overlaps with the opening 7, the storage bin 2 discharges flour into the metering bin 4. Of course, when the flow port 303 overlaps with one of the openings 7, the other opening 7 is blocked by the blocking part. This arrangement enables alternating discharge, and the size of the blocking part can only be larger than the size of the flow port 303 in order to block the opening 7.

[0048] As a preferred option, such as Figure 4 As shown, in this embodiment, a stabilizing plate 304 is installed on the side wall of the storage bin 2. A track 305 is fixedly installed on the stabilizing plate 304, and a slider 306 that slides on the track 305 is fixedly installed on the switching plate 301. The second hydraulic cylinder 302 is rotatably connected to the stabilizing plate 304. Specifically, the track 305 is arranged parallel to the two openings 7, and the slider 306 slides on the track 305. The arrangement of the track 305 and the slider 306 ensures that the switching plate 301 can maintain balance with the openings 7, preventing flour leakage when the blocking part overlaps with the openings 7. Connecting plates extend from the stabilizing plate 304 and the switching plate 301, respectively. The cylinder body and piston rod of the second hydraulic cylinder 302 are rotatably connected to the connecting plates, ensuring that the second hydraulic cylinder 302 can remain parallel, thereby improving the smoothness of the operation of the switching mechanism 3.

[0049] As a preferred implementation method, such as Figure 5 As shown, the bag clamping mechanism 5 in this embodiment includes a flow guide chamber 501 mounted on another crossbeam 6, two clamps rotatably mounted on the flow guide chamber 501, and a third hydraulic cylinder 504 that drives the clamps to rotate. It should be noted that the two clamps are arranged opposite each other, and a cylinder 505 for fitting flour bags is installed at the bottom of the flow guide chamber 501. The clamps and cylinder 505 abut against each other to clamp the flour bags. The cylinder body and piston rod of the third hydraulic cylinder 504 are rotatably connected to the two clamps respectively. This arrangement can fix the flour bags on the sleeve and also facilitates the replacement of flour bags.

[0050] As a preferred option, it remains as follows Figure 5As shown, in this embodiment, the clamping component consists of two obtuse-angled rods 502 and an arc-shaped ring 503. The two obtuse-angled rods 502 are arranged opposite each other on the flow guide chamber 501. The bottom ends of the two obtuse-angled rods 502 are rotatably connected to the two ends of the arc-shaped ring 503, and the top ends of the obtuse-angled rods 502 are rotatably connected to the flow guide chamber 501. A third hydraulic cylinder 504 is rotatably connected to the bend of the obtuse-angled rods 502. Specifically, the radius of the arc-shaped ring 503 is the same as the radius of the circular sleeve, ensuring that the arc-shaped ring 503 can clamp the flour bag on the circular sleeve. The third hydraulic cylinder 504 pushes the obtuse-angled rods 502 to rotate. The obtuse-angled rods 502 rotate around the top and the rotation point of the flow guide chamber 501 as the center, thereby allowing the arc-shaped ring 503 to move closer to or away from the circular sleeve, ensuring that the bag clamping mechanism 5 can automatically clamp the bag.

[0051] The alternating flour quantitative bagging machine in this embodiment achieves rapid and continuous quantitative bagging of flour by setting an alternating opening and closing switching mechanism 3 and a quantitative bin 4, thereby improving bagging efficiency; by setting a weighing sensor 8 and a baffle 10, the accuracy and speed of bagging are improved; by setting a hydraulic cylinder to control the baffle 10 and the switching plate 301, the stability and reliability of the bagging process are enhanced; and by setting a bag clamping mechanism 5, the clamping stability of the flour bags is improved, and errors in the bagging process are reduced.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
