[0002] Raw materials are added during production and processing. Whether in the form of granules or powders, dust is generated, polluting the production workshop and affecting product quality. This necessitates remote material feeding, separating the production workshop from the raw material warehouse. Current equipment on the market typically weighs and mixes the various raw materials before delivering them to the production workshop. Conventional powders are delivered via negative pressure, but their high density and tendency to agglomerate during transport, coupled with their small particle size and surface tension, can easily clog the vacuum suction port.

[0003] This case was created to solve the above problems. Summary of the Invention

[0006] (2) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automated raw material storage, distribution and transmission system, including a batching tank and multiple powder storage tanks for storing powder. The powder storage tank is connected to the batching tank through a connecting pipe. A control valve is provided on the connecting pipe between the powder storage tank and the batching tank. The powder storage tanks are all located above the batching tank, and the distribution is completed by the deadweight of the powder located at a high place. The connecting pipe is provided with an arch-breaking component at the connection between the powder storage tank, and a gradual guide mechanism is provided at the bend of the connecting pipe. The powder can be discharged in the connecting pipe under the action of the arch-breaking component and the gradual guide mechanism.

[0008] As a preferred solution, further, the arch-breaking mechanism includes a limit seat that is connected to the connecting pipe and the powder storage tank and is connected to the upper and lower parts of the limit seat. An expansion ball that is connected to the upper and lower parts of the limit seat is provided in the limit seat. The expansion ball is respectively connected to the powder storage tank and the connecting pipe, and the upper and lower ports are fixed on the inner wall of the limit seat. There is a surplus space between the outer side of the expansion ball and the limit seat.

[0009] As a preferred solution, further, the expandable sphere is deformable under stress and is made of any one of jute fiber, synthetic fiber and silica gel.

[0010] As a preferred solution, further, a through groove is opened on the relative inner side of the limit seat, and a push block is placed in it. The outer side of the push block is connected by a push rod, and the push rod applies inward thrust to stir the expanded sphere filled with powder inside.

[0011] As a preferred embodiment, the powder storage tank is placed around a circle, and the horizontal external force applied to the push rod is a cam driven by a motor, wherein the distance between the tip of the cam and the axis is larger than the distance between the inner end of the push rod and its axis.

[0012] As a preferred solution, further, a curved pipe is connected to the turning point of the connecting pipe, a guide plate is provided on the outer arc side of the curved pipe, a hinge seat is connected to the inner middle part of the inner side of the guide plate, and both ends of the guide plate are connected to the outer inner wall of the curved pipe through flexible connecting belts, forming a spatial seal for the inner hinge seat.

[0015] (3) Beneficial effects

[0016] After adopting the above technical solution, the automated raw material storage, distribution and transmission system provided by the present invention has the following beneficial effects compared with the prior art:

[0017] 1. Use multiple powder storage tanks at high positions, and use their own weight to deliver to the connected batching tanks below. There is no need to set up negative pressure delivery at each powder storage tank, and the powder storage tank itself can also store powder.

[0018] 2. A vertically penetrating stopper is installed at the junction of the connecting pipe and the powder storage tank. An expansion sphere is installed within the stopper. Under normal conditions, there is excess space between the outer side of the expansion sphere and the stopper. This allows the expansion sphere to be squeezed outward when the powder falls, preventing instantaneous blockage. Furthermore, an external driving force is used to continuously and repeatedly apply external force to the expansion sphere during the feeding process.

[0019] 3. Connect an elbow to the turning point of the connecting pipe. A guide plate is installed on the outer arc side of the elbow. A hinge is connected to the middle of the inner side of the guide plate. A spring is installed on one side to realize the lever principle corresponding to the inclined surface of the feeding point. The gradual transition of the feeding point is achieved through forced swing. Secondly, the spring can be replaced with an electromagnet and a magnet. When energized, the electromagnet generates a repulsive force with the same pole as the magnet. Then, intermittent power can be used to achieve active deflection of the guide plate, making it difficult for powder to accumulate and clog at the turning point of the connecting pipe.

DETAILED DESCRIPTION

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0029] See attached Figure 1As shown, an automated raw material storage, distribution and transmission system includes a batching tank 2, above which is a powder storage tank 1, which is connected by a connecting pipe 6. A control valve is installed on the connecting pipe 6 between the powder storage tank 1 and the batching tank 2. The batching tank 2 distributes and mixes various raw materials, and then transfers them to the connected raw material tank 3 for use.

[0030] The design of this embodiment is based on the fact that conventional powder materials are delivered by negative pressure, but due to their high density, they tend to agglomerate during delivery, and their small particle size and surface tension can easily block the vacuum suction port. Therefore, multiple powder storage tanks 1 are installed at a high position, and their deadweight is used to deliver the powder to the connected batching tanks 2 below. This eliminates the need for negative pressure delivery at each powder storage tank 1, and the powder storage tanks 1 themselves can also store the powder.

[0031] Considering that one batching tank 2 needs to be matched with multiple powder storage tanks 1 to achieve batching, and each powder storage tank 1 has its own space, it is impossible for each powder storage tank 1 to be located directly above the batching tank 2. As a result, the connecting pipes 6 between them will be bent at a certain angle, which in turn causes the powder to easily become blocked during the distribution process. Therefore, this application mainly focuses on optimizing and improving the structure of the locations where blockage is likely to occur during the delivery process, as follows.

[0032] like Figure 2 As shown, at the discharge outlet of the powder storage tank 1, it is easy to generate agglomeration at the connection point of the connecting pipe 6, resulting in instantaneous blockage during discharge. Therefore, a limit seat 15 that passes through the upper and lower parts is set at the connection point of the connecting pipe 6 and the powder storage tank 1. An expansion ball 17 that passes through the upper and lower parts is provided in the limit seat 15. The expansion ball 17 is respectively communicated with the powder storage tank 1 and the connecting pipe 6, and the upper and lower ports are fixed on the inner wall of the limit seat 15.

[0033] Under normal conditions, there is a surplus space 16 between the outer side of the expansion sphere 17 and the limit seat 15, so that when the powder falls, the expansion sphere 17 is squeezed outward and expanded, which makes it less likely to be blocked instantly. Figure 3 The figure shows the expansion sphere 17 after expansion under force. The inner wall of the limit seat 15 at the surplus space 16 forms a support package for the expansion sphere 17 to prevent it from being damaged due to excessive force.

[0034] The expansion ball 17 can be made of a deformable material such as jute fiber / synthetic fiber, silicone, etc.

[0035] A further example is that Figure 4As shown, a through slot is provided on the inner side of the stopper seat 15, into which a push block 20 is placed. The outer side of the push block 20 is connected by a push rod 18. The push rod 18 applies an inward thrust to agitate the expanded sphere 17 filled with powder inside. This creates a force difference between the expanded sphere 17 and the agglomerated powder inside under the action of an external force, thereby greatly preventing clogging. Furthermore, a spring is connected between the push rod 18 and the outer wall of the stopper seat 15, allowing for rapid recovery when the horizontal external force on the push rod 18 is removed.

[0036] As attached Figure 5 As shown, the horizontal external force applied to push rod 18 is a cam driven by a motor. Under normal conditions, the distance between the cam's tip and the axis is greater than the distance between the inner end of push rod 18 and its axis. This allows the cam's tip to push outward when it contacts push rod 18, transmitting an external force to expand sphere 17. Combined with the spring-driven reset of push rod 18, the cam's rotation allows for continuous and repeated external force application to expand sphere 17 during feeding. It should be noted that the powder storage tank 1 must be positioned in a circular arrangement.

[0037] A further example is that Figure 6 As shown, a curved pipe is connected to the turning point of the connecting pipe 6 (the connecting pipe 6 can be disconnected and connected through the curved pipe). A guide plate 7 is installed on the outer arc side of the curved pipe. A hinge seat 8 is connected to the inner middle part of the inner side of the guide plate 7. A spring is installed on one side to realize the lever principle corresponding to the inclined surface of the feed point. The forced swinging achieves a gradual transition at the feed point. Secondly, flexible connecting strips 10 are connected to the inner wall of the outer side of the curved pipe at both ends, forming a spatial seal with the inner hinge seat 8.

[0038] As an improvement, Figure 7 As shown, the spring is replaced with an electromagnet 1211 and a magnet 11. Magnet 11 is connected to the inner side of the guide plate 7 and is placed on the outer inner wall of the curved pipe. When energized, electromagnet 1211 generates a repulsive force with the same polarity as magnet 11. Intermittent energization can then be used to achieve active deflection of the guide plate 7, making it difficult for powder to accumulate and clog at the turning point of the connecting pipe 6. Secondly, a buffer pad is connected to the contact surface of the electromagnet 1211 or magnet 11 to prevent excessive damage to the electromagnet 1211 and magnet 11 due to constant contact.

[0039] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
