[0019] like Figure 1-4 As shown, an automatic powder feeding mechanism for a cable sheath production device includes multiple storage bins 1, a feed hopper 2, a suction pump 3, a receiving box 4, multiple sealing mechanisms, and an electrical control cabinet 7. Specifically, each storage bin 1 is equipped with a pressure sensor (not shown in the figure) at its bottom. The pressure sensor can detect the weight of the powder in the storage bin 1. The feed hopper 2 is fixedly installed on a mixer 9. The suction pump 3 is fixedly installed on the mixer 9, and its outlet is connected to the feed hopper 2 through a pipe. The receiving box 4 has a hollow structure. One discharge pipe 41 and two feed pipes 42 are provided at the upper end of the receiving box 4. Both the discharge pipe 41 and the feed pipes 42 are connected to the receiving box 4. The discharge pipe 41 is connected to the inlet of the suction pump 3 through a pipe. The feed pipe 42 is connected to the storage tank 1 through a pipe. Each sealing mechanism includes a drive device 5 and a sealing plate 6. The drive device 5 is installed on the receiving box 4. The output shaft of the drive device 5 passes into the receiving box 4 and is connected to the sealing plate 6 located in the receiving box 4. The drive device 5 can drive the sealing plate 6 to move in the receiving box 4 to seal or unseal the feed pipe 42. The electrical control cabinet 7 is equipped with a PLC module. The pressure sensor detects the amount of material stored in the storage tank 1. The PLC module analyzes and receives the pressure sensor signal and controls the suction pump 3 to stop through preset logic.

[0020] In this embodiment, there are two storage tanks 1, so there are also two sealing mechanisms and two feed pipes 42. In other words, this application can automatically proportion and feed two different powders. Of course, storage tanks 1, sealing mechanisms and feed pipes 42 can be added according to the actual production situation.

[0021] In this embodiment, the feed pipe 42 is provided with an abutting step 421 at one end in the receiving box 4. The abutting step 421 is used in conjunction with the sealing plate 6. When the output shaft of the drive device 5 extends to its limit, the sealing plate 6 will abut against the abutting step, thereby sealing the feed pipe 42.

[0022] In this embodiment, a transparent observation window 43 is provided on the receiving box 4. The transparent observation window 43 is made of acrylic and fixed on the receiving box 4, so that the operator can easily observe the internal condition of the receiving box 4.

[0023] In this embodiment, each storage bin 1 is provided with a feeding port 11, through which operators can add materials to the storage bin 1.

[0024] In this embodiment, the electrical control cabinet 7 is equipped with a touch screen 71, which is electrically connected to the PLC module. The pressure sensor, the suction pump 3, and the drive device 5 are all electrically connected to the PLC module. The circuit connection adopts the conventional connection method in the prior art, so it will not be described in detail here.

[0025] In this embodiment, the driving device 5 is one of an electric push rod, a pneumatic cylinder, and a hydraulic cylinder, preferably a pneumatic cylinder.

[0026] In this embodiment, a bracket 8 is also included, and the receiving box 4 is mounted on the bracket 8 via a connecting component. Specifically, the connecting component is a bolt, that is, the receiving box 4 is fixedly mounted on the bracket 8 by bolts.

[0027] This utility model relates to an automatic powder feeding mechanism for a cable sheath production device. Its working principle is described in conjunction with the accompanying drawings: The operator can input the desired powder weight via touchscreen 71, for example, the desired weight of powder in left storage bin 1 is 100kg and the desired weight of powder in right storage bin 1 is 300kg. After input, the automatic powder feeding mechanism is activated, and the right drive device 5 drives the sealing plate 6 to block the right feed port. At this time, the left feed pipe 42 and the right feed pipe 42 open, and the suction pump 3 works to suck out the powder from left storage bin 1. The powder in left storage bin 1 first passes through the pipe, left feed pipe 42, receiving box 4, discharge pipe 41, pipe, suction pump 3, and finally enters the feed hopper 2; when the left storage bin... When the weight of the powder in bucket 1 decreases by 100kg, the left drive device 5 drives the sealing plate 6 to block the left feed port, and the right drive device 5 drives the sealing plate 6 to move away from the right feed pipe 42. The left feed pipe 42 is closed and the right feed pipe 42 is opened. The suction pump 3 works to suck out the powder in the right storage bucket 1. The powder in the right storage bucket 1 first passes through the pipe, the right feed pipe 42, the receiving box 4, the discharge pipe 41, the pipe, the suction pump 3, and the pipe, and finally enters the feed hopper 2. When the weight of the powder in the right storage bucket 1 decreases by 300kg, the suction pump 3 stops working, completing the powder proportioning and automatic feeding.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
