[0026] Example

[0027] like Figure 1-2 As shown, an embodiment of the utility model provides a continuous feeding system based on a loss-in-weight feeder, comprising: a first loss-in-weight feeder 110 and a second loss-in-weight feeder 120; wherein the discharge port of the first loss-in-weight feeder 110 cooperates with the feed port of the second loss-in-weight feeder 120; and is used to transfer the material in the first loss-in-weight feeder 110 to the second loss-in-weight feeder 120.

[0028] It should be noted that, as those skilled in the art should know, the loss-in-weight feeder includes a hopper, a feeder, a weighing system and a regulator. During operation, the hopper, the material and the feeder are weighed continuously together, and the material supply amount is determined by obtaining the difference in data; wherein, the feeder includes a double-axis and a single-axis structure, therefore, the first loss-in-weight feeder can adopt a single-axis structure or a double-axis structure, and the second loss-in-weight feeder can adopt a single-axis structure or a double-axis structure, without specific limitation.

[0029] The discharge port of the first loss-in-weight feeder 110 cooperates with the feed port of the second loss-in-weight feeder 120 to transfer the material in the first loss-in-weight feeder 110 to the second loss-in-weight feeder 120. Specifically, it should be known to those skilled in the art that the material after passing through the first loss-in-weight feeder 110 is fed to the second loss-in-weight feeder 120, and the specific feeding method includes but is not limited to gravity feeding or other transportation methods, etc., which can realize the transfer of materials from the first loss-in-weight feeder 110 to the second loss-in-weight feeder 120.

[0030] In the present solution, the continuous feeding system is based on a loss-in-weight feeder, which includes two loss-in-weight feeders, wherein a first loss-in-weight feeder 110 is spaced apart from the second loss-in-weight feeder 120, and a discharge port of the first loss-in-weight feeder 110 cooperates with a feed port of the second loss-in-weight feeder 120 to transfer the material in the first loss-in-weight feeder 110 to the second loss-in-weight feeder 120; when the continuous feeding system is used for feeding, due to the setting of the first loss-in-weight feeder 110, the discharge amount of the first loss-in-weight feeder 110 can be accurately obtained, thereby obtaining the feed amount of the second loss-in-weight feeder 120. In the feeding process of the system, the problem of uncontrollable feeding process when using a single loss-in-weight feeder is effectively avoided, and the risk of inaccurate measurement errors caused by the inability to effectively obtain accurate weight data of the actual outflow of the second loss-in-weight feeder during the feeding process is reduced.

[0031] In some embodiments, both the first loss-in-weight feeder 110 and the second loss-in-weight feeder 120 are double-shaft screw feeders.

[0032] It should be noted that, as those skilled in the art should know, a loss-in-weight feeder includes a hopper and a feeder, and the feeding of the material in the hopper is completed by the feeder. In order to improve the feeding efficiency, the feeder adopts a double-axis structure.

[0033] In some embodiments, the first loss-in-weight feeder 110 is provided with a first control system, and the first control system includes a start-stop module, and the start-stop module is used to implement start-stop control of the first loss-in-weight feeder 110 .

[0036] Specifically, as those skilled in the art should know, when the material in the hopper of the second loss-in-weight feeder 120 is reduced and needs to be refilled, in order to avoid the effective operation of the second loss-in-weight feeder 120, the material output speed of the first loss-in-weight feeder 110 should be greater than the material output speed of the second loss-in-weight feeder 120. The settings of the first control system and the second control system can ensure that the above purpose is achieved.

[0037] Among them, the second control system is used to realize the feeding rate control of the second loss-in-weight feeder 120. Specifically, as those skilled in the art should know, in order to ensure the discharge volume of the second loss-in-weight feeder 120, the second control system should be able to obtain the real-time discharge weight of the first feeder in real time, so as to accurately control the real-time discharge volume of the second feeder by comparing the difference between the discharge volume of the first feeder and the theoretical increment of the second feeder; specifically, the second control system is connected to the first control system by signal, and is used to transmit the discharge data of the first loss-in-weight feeder to the second loss-in-weight feeder, so as to ensure the discharge volume of the second loss-in-weight feeder.

[0038] When the feeding of the second loss-in-weight feeder 120 is completed, the first control system can be used to realize the shutdown operation of the first loss-in-weight feeder 110.

[0039] Specifically, as those skilled in the art should know, during the feeding process, the actual discharge amount of the second loss-in-weight feeder 120 is equal to the discharge amount of the first loss-in-weight feeder 110 minus the material increase of the second loss-in-weight feeder 120.

[0041] Among them, the support surface is used to cooperate with the ground to realize the installation of the frame structure. As those skilled in the art should know, the support surface is used to support the feeding system, so the matching surface of the support surface includes but is not limited to the ground, and can be any rigid plane.

[0042] The material is transferred between the first loss-in-weight feeder 110 and the second loss-in-weight feeder 120 based on gravity, thereby achieving energy saving while ensuring the transfer.

[0043] In some embodiments, in order to ensure that the material can be effectively transferred between the first loss-in-weight feeder 110 and the second loss-in-weight feeder 120, a protective structure is further provided at the discharge port of the first loss-in-weight feeder 110, and the projection of the protective structure on the plane where the hopper entrance of the second loss-in-weight feeder 120 is located falls within the range of the hopper of the second loss-in-weight feeder 120.

[0044] In some embodiments, an extruder 300 is further included, wherein an inlet of the extruder 300 cooperates with an outlet of the second loss-in-weight feeder 120 .

[0045] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail.
