Description

Technical Field

[0001] This utility model relates to the field of weighing devices, specifically an automatic raw material feeding and weighing device. Background Technology

[0002] When weighing raw materials, manual handling is usually required. However, manual operation is relatively slow and requires frequent handling, weighing, and adding of raw materials. This not only consumes a lot of manpower but also reduces production efficiency and increases production costs. Therefore, an automatic raw material feeding and weighing device is needed.

[0003] Existing raw material weighing devices require manual handling of raw materials, which is cumbersome and affects work efficiency. They also lack filtration of raw materials, which leads to impurities affecting the accuracy of weighing. Therefore, there is an urgent need for an automatic raw material feeding and weighing device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an automatic raw material feeding and weighing device to solve the problems of existing automatic raw material feeding and weighing devices, such as the cumbersome manual handling of raw materials affecting work efficiency, and the lack of filtering of raw materials, which leads to impurities in the raw materials affecting the accuracy of weighing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic raw material feeding and weighing device, comprising a weighing device, a placing plate installed on the top of the weighing device, a support frame installed on the top of the weighing device, a feeding cylinder installed on the outer wall of the support frame, a filter basket installed on the inner wall of the feeding cylinder, bolts installed on the inner wall of the filter basket, a telescopic rod installed on the side wall of the filter basket, and a spring installed on the outer wall of the telescopic rod.

[0006] The outer wall of the feeding cylinder is fitted with a flange, the top of the feeding cylinder is fitted with a pipe, the outer wall of the pipe is fitted with a vacuum fan, and the top of the pipe is fitted with a suction hood.

[0007] Preferably, the filter basket is movably connected to the feed cylinder, and the side wall of the feed cylinder is slotted.

[0008] Preferably, the filter basket is threadedly connected to the telescopic rod, and the filter basket forms a telescopic structure with the feed cylinder through the telescopic rod.

[0009] Preferably, the spring is sleeved with the telescopic rod, and the telescopic rod is symmetrically arranged about the central axis of the filter basket.

[0010] Preferably, the suction hood is shaped like a frustum, and both the top of the suction hood and the inner wall of the pipe are threaded.

[0011] Preferably, the suction hood is threadedly connected to the pipe, and the pipe is connected to the flange of the discharge cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of a feeding cylinder, filter basket, bolts, telescopic rod and spring, can intercept impurities in the raw materials through the filter basket to prevent impurities from affecting the weighing accuracy. By pressing the telescopic rod, the filter basket can be moved downward. The elastic rebound of the spring can move the filter basket upward and generate vibration to remove the impurities blocking the filter basket and prevent blockage from affecting the feeding.

[0014] 2. This utility model uses a set of pipes, vacuum fans, and suction hoods. By starting the vacuum fans, the material is sucked into the feeding cylinder through the suction hood and pipes for feeding, which facilitates weighing. At the same time, the suction hood can be rotated to remove it from the pipes for replacement. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1-4An automatic raw material feeding and weighing device includes a weighing device 1, a placing tray 2 mounted on the top of the weighing device 1, a support frame 3 mounted on the top of the weighing device 1, a feeding cylinder 4 mounted on the outer wall of the support frame 3, a filter basket 5 mounted on the inner wall of the feeding cylinder 4, bolts 6 mounted on the inner wall of the filter basket 5, a telescopic rod 7 mounted on the side wall of the filter basket 5, and a spring 8 mounted on the outer wall of the telescopic rod 7. The filter basket 5 is movably connected to the feeding cylinder 4, and the side wall of the feeding cylinder 4 is slotted. The filter basket 5 is threadedly connected to the telescopic rod 7, and the filter basket 5 is connected to the telescopic rod via the telescopic rod. 7 and the feeding cylinder 4 form a telescopic structure. The spring 8 is sleeved with the telescopic rod 7, and the telescopic rod 7 is symmetrically arranged about the central axis of the filter basket 5. When using the device, the filter basket 5 can intercept impurities in the raw materials to prevent impurities from affecting the weighing accuracy. By pressing the telescopic rod 7, the filter basket 5 can be moved downward, and the spring 8 can be compressed. Then, the elastic rebound of the spring 8 can be used to push the telescopic rod 7 and the filter basket 5 and generate vibration to remove the impurities that are blocked on the filter basket 5, so as to prevent blockage and affect the feeding.

[0023] Please see Figure 1-4 An automatic raw material feeding and weighing device is disclosed. A flange 9 is installed on the outer wall of a feeding cylinder 4, a pipe 10 is installed on the top of the feeding cylinder 4, a vacuum blower 11 is installed on the outer wall of the pipe 10, and a suction hood 12 is installed at the top of the pipe 10. The suction hood 12 is shaped like a frustum, and both the top of the suction hood 12 and the inner wall of the pipe 10 are threaded. The suction hood 12 is threadedly connected to the pipe 10, and the pipe 10 is flanged to the feeding cylinder 4. When using the device, the vacuum blower 11 is started, and the suction hood 12 is used to suck the material into the pipe 10 and then transfer it to the feeding cylinder 4 for feeding, which facilitates weighing. At the same time, the suction hood 12 can be rotated to remove it from the pipe 10 for replacement.

[0024] Working principle: In use, first move the device to a suitable position, then rotate the suction hood 12 to remove it from the pipe 10, replace it with a suction hood 12 of a suitable shape, and then start the vacuum blower 11. The suction hood 12 is used to suck the material into the pipe 10, and then the material is transferred to the discharge cylinder 4 through the pipe 10. The filter basket 5 in the discharge cylinder 4 can filter and intercept impurities in the material. When the filter basket 5 becomes clogged, the telescopic rod 7 is pressed down, which moves the filter basket 5 downward, compressing the spring 8. The elasticity of the spring 8 then rebounds, pushing the telescopic rod 7 and the filter basket 5 downward and generating vibration, which removes the impurities clogging the holes of the filter basket 5. The filtered material is then transferred to the placement tray 2 and weighed using the weighing device 1. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
