Description

Technical Field

[0001] The present application relates to the technical field of weighing modules, and in particular to a raw material feeding trough for precise weighing. Background Art

[0002] The present application discloses a raw material feeding tank with accurate weighing. The conventional feeding device puts the raw material into the feeding tank, and the feeding tank transmits data to the automatic control device through the weighing instrument. During the feeding process, when the feeding tank reaches the set weight, the feeding is stopped. During the feeding process, the weighed weight of the ingredients is inevitably wrong, and the impact force generated by the raw material on the feeding tank body when it is put in will also cause the error of the feeding tank weighing.

[0003] With regard to the above-mentioned related technologies, the impact force generated on the tank body when the raw materials are added will cause errors in the weighing of the feeding tank, which is not conducive to the accurate weighing of the raw materials. Utility Model Content

[0004] In order to improve the measurement accuracy of the weighing structure of a feeding trough, the present application provides a raw material feeding trough for precise weighing.

[0005] The present application provides a raw material feeding trough for accurate weighing, which adopts the following technical solution:

[0006] A precisely weighed raw material feeding trough, comprising:

[0007] Trough;

[0009] The number of buffer mechanisms is equal to that of the weighing mechanisms, and the number of buffer mechanisms is equal to that of the weighing mechanisms, and all of them are installed on the weighing mechanisms in groups of no less than four.

[0010] By adopting the above technical solution, when the user adds raw materials to the trough, the weighing mechanism can measure the weight of the raw materials in the trough in real time. At the same time, the weighing structure can check whether the trough is tilted. The buffer mechanism can play a buffering role when adding raw materials to the trough, buffering the impact force on the trough when adding raw materials, thereby improving the measurement accuracy of the weighing mechanism.

[0011] Optionally, the weighing mechanisms of at least four groups each include:

[0012] A bearing plate, the bearing plate is fixedly mounted on the peripheral side of the trough;

[0013] An upper connecting member, the upper connecting member is fixedly mounted on the bearing plate;

[0019] By adopting the above technical solution, when adding raw materials to the trough, the load-bearing plate transmits the weight to the weighing sensor, and the weighing sensor can measure the weight of the raw materials in the trough. The upper connecting piece and the lower connecting piece fix the position of the weighing sensor. The upper limit column and the lower limit column can prevent the shaking caused when the raw materials are added to the trough, which affects the measurement accuracy of the weighing sensor, so that the data measured by the weighing mechanism is more accurate.

[0020] Optionally, the buffer mechanisms, the number of which is equal to that of the weighing mechanisms, include:

At the same time, after being squeezed, the airbag will produce a pressure effect on the movable end of the telescopic rod through the air pipe, and the movable end of the telescopic rod will produce a top effect on the trough through the top plate after being pressed, thereby producing a fixing effect on the trough, and the trough will be more stable under the action of the close fit of the top plate.

[0030] Optionally, at least two rubber pads are fixedly mounted on the top plate.

[0031] By adopting the above technical solution, the rubber pad will increase the friction with the material trough, so that the adhesion of the top plate to the material trough is more stable.

[0053] The following is combined with Figure 1-2 This application is described in further detail.

[0054] The embodiment of the present application discloses a raw material feeding trough for precise weighing.

[0055] Reference Figure 1 and Figure 2 The raw material feeding trough for precise weighing includes: a trough 1, at least four groups of weighing mechanisms 2, at least four groups of weighing mechanisms 2 evenly installed on the side of the trough 1, and buffer mechanisms 3 equal in number to the weighing mechanisms 2, and the buffer mechanisms 3 are all installed on the weighing mechanisms 2.

[0056] When the user uses the raw material feeding trough 1 and adds raw materials to the trough 1, the weighing mechanism 2 can measure the weight of the raw materials in the trough 1 in real time, and the weighing mechanism 2 can also check whether the trough 1 is tilted. The buffer mechanism 3 can play a buffering role when the raw materials are added to the trough 1, buffering the impact force of the raw materials on the trough 1, and improving the measurement accuracy of the weighing structure.

[0057] Reference Figure 1 and Figure 2The weighing mechanism 2 includes: a bearing plate 21 fixedly mounted on the side of the trough 1, an upper connecting member 22 fixedly mounted on the bearing plate 21, a weighing sensor 23 with a clearance fit with the upper connecting member 22, a lower connecting member 24 with a clearance fit with the weighing sensor 23, a fixing plate 25 fixedly connected to the lower connecting member 24, two upper limit posts 26 symmetrically and fixedly mounted on both sides of the bearing plate 21, and two lower limit posts 27, the two lower limit posts 27 are symmetrically and fixedly mounted on both sides of the fixing plate 25, a groove is opened on the lower limit post 27, and one end of the upper limit post 26 is slidably mounted in the groove.

[0058] After the user adds raw materials to the trough 1, the weighing sensor 23 can measure the weight of the raw materials. The upper limit column 26 and the lower limit column 27 can prevent the raw materials from shaking during the process of adding the raw materials to the trough 1, which affects the measurement accuracy of the weighing sensor 23, so that the weighing mechanism 2 measures data more accurately.

[0059] Reference Figure 1 and Figure 2 The buffer mechanism 3 includes: a bottom plate 31 for fixing and installing the trough 1, a box body 32 fixedly installed on the bottom plate 31, a pressing plate 33 fixedly connected to the fixing plate 25, the pressing plate 33 is slidably installed in the box body 32, an air bag 34 fixedly installed in the box body 32, the air bag 34 abuts against the pressing plate 33, an air pipe 35, one end of the air pipe 35 is connected with the air bag 34, a telescopic rod 36, a fixed end of the telescopic rod 36 is fixedly installed on the bottom plate 31, and the other end of the air pipe 35 is connected with the fixed end of the telescopic rod 36, a top plate 37, one side of the top plate 37 is fixedly connected with the movable end of the telescopic rod 36, and the other side of the top plate 37 can be closely fitted with the trough 1, and a spring 38, the spring 38 is sleeved on the telescopic rod 36, one end of the spring 38 is fixedly connected with the movable end of the telescopic rod 36, and the other end of the spring 38 is fixedly connected with the top plate 37.

[0060] After adding raw materials to the trough 1, the weight of the raw materials on the trough 1 will be transmitted to the buffer mechanism 3 through the fixed plate 25 of the weighing mechanism 2. The airbag 34 of the buffer mechanism 3 will play a buffering role on the trough 1 after being squeezed, reducing the impact force generated when adding raw materials and improving the accuracy of raw material weighing. At the same time, after being squeezed, the gas inside the airbag 34 will produce a pressure effect on the movable end of the telescopic rod 36 through the air pipe 35. After the movable end of the telescopic rod 36 is pressurized, it will exert a top effect on the trough 1 through the top plate 37, thereby producing a fixing effect on the trough 1. The trough 1 will be more stable under the tight fit of the top plate 37.

[0061] Reference Figure 1 and Figure 2 The material trough 1 is provided with an observation window 11 on the peripheral side, a discharge valve 12 is provided at the bottom, and a temperature sensor is provided inside the material trough 1 .

[0062] The user can check the internal situation of the trough 1 through the observation window 11, and can find out in time when there is a problem inside the trough 1. When the trough 1 stops working or is under maintenance, the user can discharge the raw materials in the trough 1 through the discharge valve 12. The user can measure the internal temperature of the trough 1 through the temperature sensor.

[0063] Reference Figure 1 and Figure 2 A rubber pad 39 is installed on the top plate 37, and the rubber pad 39 increases the friction with the material trough 1, so that the adhesion of the top plate 37 to the material trough 1 is more stable.

[0064] Reference Figure 1 and Figure 2 A silicone pad 28 is fixedly installed at the lower end of the limiting column, and the silicone pad 28 can buffer the impact force generated when adding materials.

[0065] The implementation principle of the raw material feeding trough for precise weighing in the embodiment of the present application is as follows: when the user adds raw materials to the trough 1, the limit column will stabilize the weighing mechanism 2 and reduce the shaking during the feeding. At the same time, the silicone shock-absorbing pad of the upper limit column 26 will produce a buffering effect, and the airbag 34 of the buffer mechanism 3 will also produce a buffering effect during the feeding, thereby reducing the influence of the shaking and impact force generated during the feeding on the weighing data and improving the measurement accuracy of the weighing structure.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
