Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to an automatic weighing equipment for flour processing. Background Art

[0002] Flour, also known as wheat flour, is a powder made from wheat that has been ground into powder. It is one of the common food ingredients and one of the staple food ingredients in most parts of northern China.

[0003] The Chinese utility model with authorization announcement number CN220380591U discloses a weighing device for wheat flour processing. When in use, the device drives the movable plate to move through multiple sets of clamping motors to fix the four corners of the bag opening, and then drives the bag opening to close through a second electric push rod to ensure that the wheat flour will not fly during the discharge and weighing process. However, in actual use, the device has certain defects. For example, the movable plates are located at the four corners and their spacing cannot be adjusted. When clamping smaller bags, it is easy to cause the four corners of the bag to be over-clamped, and even cause the bottom of the bag to be lifted, making it impossible to effectively fix the position of the bag, and thus unable to accurately weigh the flour. Therefore, it is necessary to propose an automatic weighing device for flour processing to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an automatic weighing device for flour processing.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] Preferably, the end of the sliding rod is fixedly connected to a limiting block, and the radius of the limiting block is larger than the radius of the fixing plate.

[0010] Preferably, a spring is sleeved on the outer wall of the sliding rod, one end of the spring is fixedly connected to the fixing plate, and the other end of the spring is fixedly connected to the limiting block.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the present invention, the rotation of the double-headed threaded rod drives the two sets of clamping plates to slide, which can evenly cover and clamp the bag opening. The arc shape of the inner wall of the slide groove matches the design of the clamping plates, making the contact between the clamping plates and the bag opening smoother, avoiding the situation of local excessive clamping, ensuring that the clamping force is evenly distributed on the bag opening, and avoiding the risk of the bottom of the bag being lifted or deformed, thereby accurately weighing the flour.

[0016] 2. The utility model provides a spring that provides gentle elastic pressure, further ensuring that the clamping force is neither too large nor too small, thereby avoiding the stability of the bag opening being affected by clamping too tightly or too loosely. Therefore, the bag can maintain a stable posture and can be accurately fixed in position during the weighing process regardless of its size, thereby achieving accurate weighing.

[0017] The curved clamping plate and spring design effectively avoids bag instability caused by uneven or excessive clamping in traditional equipment, ensuring accurate and stable bag weighing throughout the entire weighing process. Furthermore, through more precise bag opening coverage and closure, this equipment effectively reduces flour dust, improves the working environment, and enhances weighing accuracy and production efficiency. These two improvements not only enhance the equipment's reliability and adaptability, but also better meet the needs of flour processing operations at different scales.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-5 , an automatic weighing device for flour processing, including a frame 1, the outer wall of the frame 1 is fixedly connected to a storage barrel 2, the lower end surface of the storage barrel 2 is fixedly connected to a hopper 17, and is communicated with the interior of the storage barrel 2, a bottom plate 3 is installed on the upper end of the frame 1, an electronic weighing plate 4 is embedded in the end surface of the bottom plate 3, a chute 5 is opened on the outer wall of the hopper 17, the inner wall of the chute 5 is arc-shaped, two groups of side plates 6 are fixedly connected to the inner wall of the frame 1, a double-headed threaded rod 7 is rotatably connected between the two groups of side plates 6, and two groups of sliders 11 are threadedly connected on the threaded section of the double-headed threaded rod 7. The outer walls of the two groups of sliders 11 Both are equipped with clamping plates 10, and the inner walls of the clamping plates 10 are in contact with the inner walls of the chute 5; with the help of two sets of clamping plates 10 sliding into the inside of the chute 5, the bag opening arranged at the discharge port of the hopper 17 can be covered, effectively preventing wheat flour from flying due to the bag opening not being completely closed or the unstable position during the discharge process, reducing dust pollution, and improving the working environment. At the same time, the design of the arc-shaped clamping plates 10 can ensure that the contact between the clamping plates 10 and the bag is smoother and more uniform, and no excessive clamping force will be applied at a certain point, thereby avoiding local excessive clamping that causes the bottom of the bag to be lifted.

[0026] The outer wall of the slider 11 is fixedly connected to a connecting rod 12, and the end of the connecting rod 12 is fixedly connected to a fixing plate 13. The outer wall of the fixing plate 13 is slidably connected to a sliding rod 14, and the end of the sliding rod 14 is fixedly connected to the clamping plate 10. The two sets of side plates 6 are fixedly connected to the limit rod 8. The two sets of sliders 11 are slidably connected to the outer wall of the limit rod 8, and the end of the sliding rod 14 is fixedly connected to the limit block 15. The radius size of the limit block 15 is larger than the radius size of the fixing plate 13. The outer wall of the sliding rod 14 is sleeved with a spring 16. One end of the spring 16 is fixedly connected to the fixing plate 13, and the other end of the spring 16 is fixedly connected to the limit block 15; the setting of the spring 16 can provide a certain elastic pressure for the clamping plate 10. This pressure enables the clamping plate 10 to apply force evenly and softly when clamping the bag opening, avoiding local over-clamping and preventing the bottom of the bag from being lifted or deformed. At the same time, it ensures that the clamping plate 10 can adjust the pressure according to the size of the bag opening, which can not only adapt to bags of different sizes, but also maintain the stability of the bag opening to avoid flour flying.

[0027] The inner walls of the two sets of clamping plates 10 are both curved and consistent with the curvature of the inner wall of the chute 5. A solenoid valve is installed in the hopper 17. The contact surfaces between the two sets of clamping plates 10 and the inner wall of the chute 5 are both installed with rubber pads. One set of side plates 6 is fixedly connected to the side wall of a servo motor 9, and the end of the output shaft of the servo motor 9 is coaxially fixedly connected to the double-headed threaded rod 7.

[0028] In the present utility model, the device is specifically used as follows: first, the bag opening is placed on the hopper 17, the operator starts the equipment, the servo motor 9 starts to run, driving the double-headed threaded rod 7 to rotate, so that the slider 11 slides along the limit rod 8, driving the clamping plate 10 to slide into the inside of the slide 5, and after the clamping plate 10 contacts the inner wall of the slide 5, it can automatically cover the bag opening. When the clamping plate 10 contacts the bag opening, the spring 16 provides a certain amount of pressure to the clamping plate 10 through elastic action, ensuring that the clamping force acts evenly and gently on the bag opening, which avoids the bag opening being clamped too tightly and prevents the bottom of the bag from being lifted or deformed.

[0029] The two groups of clamping plates 10 evenly clamp the bag opening through the arc-shaped design of the inner wall of the slide 5, ensuring that the bag opening is firmly clamped and the bag will not loosen or the bottom lift due to uneven clamping. After the bag opening is stably clamped, the wheat flour in the storage barrel 2 begins to flow into the bag through the hopper 17. The solenoid valve controls the discharge of the wheat flour to ensure a smooth and accurate discharge process. The electronic weighing plate 4 monitors the weight of the wheat flour in the bag in real time. When the weighing is completed, the solenoid valve closes to stop the discharge of the wheat flour. Then the servo motor 9 drives the double-headed threaded rod 7 to reverse, driving the clamping plate 10 to return to its initial position.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
