[0002] In the production process of power cables, the inside of the cables needs to be filled with powder and granular materials. These powder and granular materials can be talcum powder, magnesium powder and other substances. These powders are used to keep the insulation layer inside the cable from sticking. A cable powdering machine is needed to fill the cable with powder and granular materials. After the powder and granular materials inside the cable powdering machine are used up, it is necessary to add materials inside the cable powdering machine.

[0003] In the existing cable powder feeding operation, the staff generally uses a knife or other tools to cut the seal of the powder bag, and manually carries the whole powder bag, and then pours the powder inside the powder bag into the cable powder machine. This method requires manual operation, and during the transportation process, the powder bag may spill from the cut opening, which will cause the spilled powder to pollute the working environment. Therefore, in order to solve this problem, we propose a powder feeding device for producing power cables. Utility Model Content

[0004] The purpose of the utility model is to provide a powder and granular material feeding device for producing power cables, so as to solve the problems proposed in the above-mentioned background technology that the powder and granular material bags are cut, transported, poured and fed manually, and during the transportation process, the powder and granular material bags may spill out from the cut opening, thereby causing the spilled powder and granular material to pollute the working environment.

[0008] Preferably, one end of the hook frame is provided with a sharp structure, and the sharp structure is pressed against the surface of the powder and granular material bag.

[0009] Preferably, springs are connected to the front and rear ends of the other side surface of the movable plate, and the movable plate is connected to the side end wall inside the feeding frame through two springs.

[0010] Preferably, both sides of the rear end of the feeding frame are fixedly connected with an electric push rod body, the front end of the electric push rod body is movably provided with a push rod movable end, the push rod movable end extends through the interior of the feeding frame, and the front end of the push rod movable end is fixedly connected to the slider.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model obliquely inserts the whole powder and granular material bag on one side end surface of the movable plate, so that the bearing plate at the lower end of the feeding frame supports the whole powder and granular material bag, and then starts the electric push rod body at the rear end of the feeding frame, so that the electric push rod body is energized and the push rod movable end at the front end of the electric push rod body moves horizontally.

[0014] One end of the slider is fixedly connected with a blade, and the edge of the blade is pressed against the lower surface of the powder bag, so that the blade on one side of the slider can cut the lower end of the powder bag, thereby opening the lower end of the powder bag. Under the action of gravity, the powder and granules inside the powder bag continuously fall downward into the cable powder machine on the lower side of the movement. This arrangement enables the overall device to automatically open the powder bag and automatically discharge the material, replacing manual dumping, thereby avoiding the phenomenon of powder and granules spilling during the manual dumping process;

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 4 The utility model provides an embodiment: a powder and granular material feeding device for producing power cables, comprising a feeding frame 2, a cable powder machine 1 is fixedly connected to the lower end of the feeding frame 2, a three-phase motor 3 is fixedly connected to the rear ends of both sides of the feeding frame 2, a polarization disk 4 is fixedly connected to the output shaft at the front end of the three-phase motor 3 through a coupling, and movable plates 7 are movably provided on the inner sides of the side walls on both sides of the feeding frame 2, wherein the polarization disk 4 rotates through the output end of the front end of the three-phase motor 3, and the polarization disk 4 vibrates the movable plate 7 on one side;

[0023] A powder and granular material bag 5 is obliquely inserted on one side of the movable plate 7, and a supporting plate 12 is provided on one side of the lower end of the movable plate 7. The front and rear ends of the supporting plate 12 are fixedly connected to the front and rear ends of the inner side of the feeding frame 2, and the upper end of the supporting plate 12 is in contact with the lower end of the powder and granular material bag 5. The front and rear sides of the inside of the feeding frame 2 are laterally fixedly connected with slide rails 9, and the slide rails 9 are movably provided with a slider 10 toward one side end of the powder and granular material bag 5.

[0024] The setting of the bearing plate 12 at the lower end of the feeding frame 2 supports the entire powder and granular material bag 5. The front and rear ends of both sides of the upper end of the feeding frame 2 are fixedly connected with hook frames 8, and the hook frames 8 are set as a bending structure. One end of the hook frame 8 is provided with a sharp structure, and the sharp structure is pressed on the surface of the powder and granular material bag 5. When the powder and granular material bag 5 is placed on one side of the movable plate 7, the sharp structure on the hook frame 8 penetrates into the powder and granular material bag 5, and the hook frame 8 can fix the entire powder and granular material bag 5. This setting further improves the fixing performance of the two hook frames 8 on the powder and granular material bag 5.

[0025] The front and rear ends of the other side of the movable plate 7 are connected with springs 6, and the movable plate 7 is connected between the side end walls inside the feeding frame 2 through two springs 6. The setting of the spring 6 provides elastic force to the movable plate 7. Both sides of the rear end of the feeding frame 2 are fixedly connected with an electric push rod body 14, and the front end of the electric push rod body 14 is movably provided with a push rod movable end 13, which extends through the interior of the feeding frame 2, and the front end of the push rod movable end 13 is fixedly connected to the slider 10.

[0026] When the device is in use, the whole powder and granular material bag 5 is first obliquely inserted on one side end surface of the movable plate 7, so that the bearing plate 12 at the lower end of the feeding frame 2 supports the whole powder and granular material bag 5, and then the electric push rod body 14 at the rear end of the feeding frame 2 is started, so that the electric push rod body 14 is energized and the push rod movable end 13 at the front end of the electric push rod body 14 moves horizontally. The front end of the push rod movable end 13 must be fixedly connected to the slider 10, and the push rod movable end 13 drives the front end slider 10 to move horizontally forward and backward on the slide rail 9, wherein One end of the slider 10 is fixedly connected with a blade 11, and the edge of the blade 11 is pressed against the lower surface of the powder bag 5, so that the edge of the blade 11 can cut the lower end of the powder bag 5, thereby making the lower end of the powder bag 5 open.

After the polarization disk 4 rotates, the movable plate 7 vibrates, and the spring 6 on one side of the movable plate 7 provides an elastic force to the movable plate 7, and this elastic force further increases the vibration amplitude of the movable plate 7. Under the vibration provided by the polarization disk 4 and the movable plate 7, the powder and granular material inside the powder and granular material bag 5 falls from the opening faster, and this arrangement accelerates the efficiency of the device in feeding the cable powder passing machine 1.
