[0034] In order to solve the problem that the manual weighing and batching method in the prior art is not only time-consuming and labor-intensive but also has poor weighing accuracy, the present application provides a weighing and batching device.

[0035] like Figures 1 to 6 As shown, the weighing and batching device includes a first material storage structure 10, a weighing device 20, a second material storage structure 30, a spiral feeding mechanism 40, a mixing structure 50 and a control module. The first material storage structure 10 is used to cache the main material, the weighing device 20 includes a base 21, a weighing sensor 22 and a support base 23, the weighing sensor 22 is arranged on the base 21, and the support base 23 is arranged on the weighing sensor 22. The second material storage structure 30 is arranged on the support base 23, and the second material storage structure 30 includes a material storage body 31 and a discharge pipe 32 connected to each other, and the material storage body 31 is used to store auxiliary materials. The spiral feeding mechanism 40 includes a motor 41 and a screw 42, the motor 41 is connected to the screw 42 to drive the screw 42 to rotate; the screw 42 extends into the discharge pipe 32. The mixing structure 50 is connected to the discharge port of the first material storage structure 10, and at least part of the discharge pipe 32 extends into the mixing structure 50. The control module is electrically connected to the weighing sensor 22 and the motor 41. The control module controls the speed and start and stop of the motor 41 to adjust the weight of the auxiliary material entering the mixing structure 50.

[0036] By applying the technical solution of this embodiment, the weighing device 20 can automatically and accurately weigh the auxiliary materials in the second material storage structure 30 to replace manual weighing of the auxiliary materials, which not only improves the weighing efficiency and reduces the labor intensity of the staff, but also improves the weighing accuracy, and solves the problem that the manual weighing method of mixing ingredients in the prior art is not only time-consuming and labor-intensive but also has poor weighing accuracy, so that the auxiliary materials can be accurately and evenly added to the mixing structure 50 to mix with the main materials.

[0037] In this embodiment, when the weighing value of the weighing sensor 22 is less than or equal to the preset weight value, the motor 41 is controlled to stop running through the control module. In this way, by immediately stopping the motor 41 when the auxiliary material reaches the preset weight, the waste of resources and the decline of product quality caused by excessive addition of auxiliary materials are avoided, and the intelligence level of the weighing batching device is improved.

[0038] Specifically, when the weighing value of the weighing sensor 22 is less than or equal to the preset weight value, it is determined that there is no auxiliary material in the second material storage structure 30, and the motor 41 is controlled to stop running to avoid waste of resources. When the weighing value of the weighing sensor 22 is greater than the preset weight value, it is determined that a predetermined amount of auxiliary material is present in the second material storage structure 30, and the motor 41 is started to drive the screw 42 to rotate, so as to transport the auxiliary material to the mixing structure 50 for mixing with the main material.

[0039] like Figure 5 As shown, the weighing device 20 also includes a first mounting seat 24. The first mounting seat 24 is arranged on the machine base 21, and the first mounting seat 24 has a first through hole. The screw 42 passes through the first through hole and extends into the mixing structure 50. Among them, the weighing and batching device also includes a second mounting seat 70, and the motor 41 is arranged on the second mounting seat 70, and the second mounting seat 70 is connected to the second material storage structure 30. In this way, the above arrangement facilitates the maintenance and adjustment of the weighing and batching device, and improves the versatility of the weighing and batching device. At the same time, the above arrangement makes the internal structural layout of the weighing and batching device more reasonable and compact, and realizes the miniaturized design of the weighing and batching device.

[0040] In this embodiment, the motor 41 is a servo motor. In this way, the use of the servo motor as a driving device ensures the stability and accuracy of the feeding, thereby meeting the strict requirements of the feed industry and the injection molding industry on the raw material ratio, and improving the production quality and safety.

[0041] like Figure 5 and Figure 6 As shown, the base 21 has a receiving cavity, and a socket 25 is provided on the base 21. The weighing batching device also includes a battery, which is provided in the receiving cavity to power the weighing sensor 22 and the socket 25. The socket 25 is electrically connected to the plug 411 of the motor 41. In this way, the above arrangement makes the installation and use of the weighing batching device more flexible and is not limited by the power supply position. At the same time, the above arrangement improves the power safety of the weighing batching device, avoids electric shock accidents, and improves the safety performance of the weighing batching device.

[0042] Specifically, the design of the built-in storage battery and the socket 25 eliminates the dependence on a fixed power source, so that the weighing and batching device can operate normally in an environment where the power supply condition is unstable or lacking, thereby ensuring the continuity and accuracy of the weighing and batching.

[0043] In this embodiment, the mixing structure 50 has a first feed inlet and a second feed inlet, the first feed inlet is connected to the discharge port of the first material storage structure 10, and the second feed inlet is connected to the discharge pipe 32; wherein the first feed inlet is located above the second feed inlet. In this way, the above layout ensures the full mixing of the main and auxiliary materials, and also makes the internal structure layout of the weighing and batching device more reasonable and compact, thereby improving the space utilization rate.

[0044] Specifically, the second material storage structure 30 is located on one side of the mixing structure 50, and the first material storage structure 10 is located above the mixing structure 50. By setting the main feed port above the auxiliary feed port, gravity is used to assist material mixing, which effectively improves the mixing uniformity of the main and auxiliary materials.

[0045] Optionally, a first transparent window 51 is provided on the mixing structure 50; and / or a second transparent window 33 is provided on the second material storage structure 30. In this way, the above-mentioned setting of the transparent window facilitates the staff to observe the storage and mixing of materials, and improves the user experience.

[0046] In this embodiment, a first transparent window 51 is provided on the mixing structure 50, and a second transparent window 33 is provided on the second material storage structure 30. Thus, the above-mentioned arrangement of the first transparent window 51 and the second transparent window 33 provides an intuitive observation angle, and the operator can monitor the storage and mixing of materials in real time, so as to adjust the batching parameters in time.

[0047] like Figure 1 and Figure 4 As shown, a filter screen 34 is provided at the feed inlet of the second material storage structure 30. Thus, the above-mentioned setting of the filter screen 34 ensures the purity of the auxiliary material, avoids the mixing of impurities, ensures the quality of the final product, and improves the yield and reliability of the product.

[0048] Optionally, the second material storage structure 30 has a second through hole, a material storage cavity and a third through hole, the second through hole and the third through hole are both connected to the material storage cavity, and the screw 42 passes through the second through hole, the third through hole and the first through hole in sequence and then extends into the mixing structure 50; wherein the second mounting seat 70 and the first mounting seat 24 are respectively located on both sides of the second material storage structure 30. In this way, the above arrangement optimizes the flow path of the material and improves the batching efficiency.

[0049] Specifically, the above-mentioned optimized material flow path design, combined with the efficient spiral feeding mechanism, makes the batching process smoother and shortens the batching time to a great extent.

[0050] Optionally, the weighing device 20 further includes a detection device, which is arranged at the discharge pipe 32 to detect whether there is auxiliary material at the discharge port of the discharge pipe 32. The detection device is electrically connected to the control module, and when the detection device detects that there is auxiliary material at the discharge port, the control module controls the motor 41 to continue to operate. In this way, the above arrangement ensures the continuous supply of auxiliary materials, avoids interruptions in the batching process, improves the continuity and stability of weighing, and improves the weighing efficiency.

[0051] In this embodiment, the weighing sensor 22 weighs the auxiliary materials at every preset time interval, and the motor 41 is controlled to stop running by the control module during the weighing process of the auxiliary materials by the weighing sensor 22. In this way, the above-mentioned timing weighing and adjustment design ensures the stability of the batching process, ensures the continuous stability of the batching process, thereby avoiding the batching error caused by long-term operation, and improving the production quality and safety of food.

[0052] like Figure 2 As shown, the weighing and batching device further includes a suction pipe 60, and both ends of the suction pipe 60 are respectively connected to the second material storage structure 30 and the feeding device.

[0053] Specifically, the working principle of the weighing batching device is as follows:

[0054] When auxiliary materials are stored in the discharge pipe 32, the detection value F0 of the weighing sensor 22 is G+M; when auxiliary materials are not stored in the discharge pipe 32, the detection value F1 of the weighing sensor 22 is G, and the weight of the auxiliary materials fed into the mixing structure 50 is F=F0-F1=G+MG=M. The feeding weight of the screw 42 is controlled by adjusting the rotation speed of the servo motor, thereby realizing automatic batching weighing.

[0055] In this embodiment, the weighing device takes 2 seconds for each weighing, and the servo motor stops once.

[0056] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0057] The weighing and batching device includes a first material storage structure, a weighing device, a second material storage structure, a spiral feeding mechanism, a mixing structure and a control module.
