[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0020] like Figures 1-9 The shown embodiment is a quantitative feeding mechanism for the production of cable insulation glue, comprising a feeding tube 1, a hopper 2 being fixedly connected to one end of the feeding tube 1, a spiral rod 3 being rotatably connected to the inner wall of the feeding tube 1, a fixed frame 4 being fixedly connected to the other end of the feeding tube 1, a movable seat 5 being provided on the fixed frame 4, a movable seat 6 being slidably fitted in the movable seat 5, a winding seat 7 being fixedly connected to the movable seat 6, a brushing spring steel cable 8 being provided in the winding seat 7, and a pushing mechanism 9 being rotatably connected to the movable seat 6.

[0021] like Figure 4As shown, a valve 101 is fixedly connected to the bottom end of the feeding tube 1, a mounting base 102 is fixedly installed on the lower side of the feeding tube 1, a discharge cover 103 is threadedly connected to the top opening of the feeding tube 1, and a stirring frame 104 is slidingly fitted at the connection between the feeding tube 1 and the hopper 2. The bottom end of the stirring frame 104 is a conical structure, and the bottom end of the stirring frame 104 is in sliding contact with the outer wall of the spiral rod 3.

[0022] like Figure 5 As shown, the middle portion of the spiral rod 3 is hollow. One end of the spiral rod 3 extends through the inner wall of the feeding tube 1 to the outside and is rotatably connected to a hollow seat 301. A liquid inlet pipe 302 is fixedly connected to one side of the hollow seat 301. The liquid inlet pipe 302 is fixedly connected to the feeding tube 1. A plurality of flushing holes 303 are formed through the outer wall of the spiral rod 3. A sealing plug 304 is slidingly provided on the inner wall of the flushing hole 303. A tension spring 305 is fixedly connected to the inner end of the sealing plug 304. The other end of the tension spring 305 is fixedly connected to the inner wall of the spiral rod 3. A hole is formed on the outer wall of one end of the spiral rod 3 located in the hollow seat 301. The tension spring 305 can drive the sealing plug 304 to reset. High-pressure cleaning fluid is injected into the hollow seat 301 through the liquid inlet pipe 302. The high-pressure cleaning fluid then pushes open the sealing plug 304 and sprays out through the flushing holes 303 on the spiral rod 3.

[0023] like Figure 6 As shown, a baffle 401 is fixedly connected to one side of the fixed frame 4, and the baffle 401 is in sliding contact with the opening of the movable seat 5. An electric push rod 402 is fixedly connected to the top of the fixed frame 4, and the other end of the electric push rod 402 is fixedly connected to the movable seat 5.

[0024] like Figure 7 As shown, a motor A501 is fixedly connected to the outer wall of one side of the moving seat 5, a transmission disk 502 is fixedly connected to the outer wall of one end of the motor A501 located inside the moving seat 5, and a plurality of protrusions 503 are fixedly provided on the inner wall of the moving seat 5.

[0025] like Figure 8As shown, both ends of the movable seat 6 are annular in structure and rotatably connected with multiple rollers 601, and the rollers 601 are arranged in sliding contact with the inner wall of the movable seat 5. A fixed rod 602 is fixedly connected to one side of the movable seat 6, and a contact wheel 603 is rotatably connected to the other end of the fixed rod 602. The contact wheel 603 is arranged in sliding contact with the protruding block 503, and a plurality of guide rods 604 are fixedly connected to one end of the movable seat 6. The guide rods 604 are slidably matched with the transmission disk 502, and a spring 605 is sleeved on the outer wall of the guide rod 604. One end of the spring 605 is fixedly connected to the movable seat 6, and the other end of the spring 605 is fixedly connected to the transmission disk 502. Motor A501 drives the connected transmission disk 502 to rotate, allowing the transmission disk 502 to drive the movable seat 6 connected to the guide rod 604 to rotate, and at the same time drive the brush spring cable 8 to rotate. Then, when the movable seat 6 rotates, the contact wheel 603 contacts the raised block 503 and is reset by the spring 605, causing the movable seat 6 to reciprocate, thereby driving the brush spring cable 8 to reciprocate. The roller 601 and contact wheel 603 reduce friction when the movable seat 6 rotates and moves.

[0026] like Figure 9 As shown, a reel 701 is rotatably connected to the inner wall of the reel seat 7. One end of the reel 701 extends through the inner wall of the reel seat 7 to the outside and is fixedly connected to a motor B702. The motor B702 is fixedly connected to the outer wall of the reel seat 7. The motor B702 drives the connected reel 701 to rotate, driving the brush spring cable 8 to be retracted into the reel seat 7.

[0027] like Figure 9 As shown, one end of the brushing spring steel cable 8 is wound on the winding shaft 701, and the outer wall of the brushing spring steel cable 8 is fixedly connected with nylon bristles 801, which are in sliding contact with the inner wall of the feeding tube 1 and the outer wall of the spiral rod 3.

[0028] By arranging a scrubbing spring steel cable 8 and arranging nylon bristles 801 on the surface of the scrubbing spring steel cable 8, the scrubbing spring steel cable 8 can be inserted into the feeding tube 1 through the pushing mechanism 9, so that the scrubbing spring steel cable 8 can move corresponding to the spiral shape of the spiral rod 3, and can effectively clean the residue on the surface of the spiral rod 3. Due to the softness of the nylon bristles 801 and the flexibility of the scrubbing spring steel cable 8, comprehensive automatic cleaning can be performed without damaging the spiral rod 3, especially the cleaning of the spiral structure area is more thorough, which not only improves the cleaning efficiency but also ensures the accuracy of quantitative feeding.

[0029] like Figure 8As shown, the pushing mechanism 9 includes two rotating shafts 901, which are rotatably connected to the inner wall of the winding seat 7. The bottom ends of the rotating shafts 901 are fixedly connected to a gear 902. The two gears 902 are meshed and driven. The bottom end of one of the rotating shafts 901 is fixedly connected to a motor C903, which is fixedly connected to the movable seat 6. The top end of the rotating shaft 901 is fixedly connected to a rubber wheel 904. The outer wall of the rubber wheel 904 is in frictional contact with the outer wall of the brush spring steel cable 8. The motor C903 drives the connected rotating shaft 901 to rotate. At this time, the rotating shaft 901 drives the rotating shaft 901 connected to the other gear 902 to rotate through the connected gear 902, so that the rotating shaft 901 can drive the connected rubber wheel 904 to rotate. At this time, the rubber wheel 904 pushes the brush spring steel cable 8, causing the brush spring steel cable 8 to extend into the feeding tube 1.

[0030] Working principle: When feeding the cable insulation glue raw material, the screw rod 3 is driven to rotate so that the screw rod 3 can contact and squeeze the stirring frame 104, so that the stirring frame 104 moves in the hopper 2, so that the raw material in the hopper 2 can fall smoothly into the feeding tube 1, and then the screw rod 3 can transport the raw material through the discharge cover 103 to complete the feeding. By controlling the rotation speed of the screw rod 3, quantitative feeding can be achieved; Then, when it is necessary to clean the screw rod 3 and the feeding tube 1, firstly, high-pressure cleaning liquid is injected into the hollow seat 301 through the liquid inlet pipe 302, and then the high-pressure cleaning liquid will push open the sealing plug 304 and spray out through the flushing hole 303 on the screw rod 3 to soak and clean the screw rod 3 and the feeding tube 1; Then, the discharge cover 103 is opened, and the electric push rod 402 is used to drive the movable seat 5 to move downward, so that the opening of the movable seat 5 is aligned with the top opening of the feeding tube 1. Then, the motor C903 is used to drive the connected rotating shaft 901 to rotate. At this time, the rotating shaft 901 will drive the rotating shaft 901 connected to another gear 902 to rotate through the connected gear 902, so that the rotating shaft 901 can drive the connected rubber wheel 904 to rotate. At this time, the rubber wheel 904 will push the brush spring steel cable 8, so that the brush spring steel cable 8 extends into the feeding tube 1 and moves along the spiral structure of the spiral rod 3 until it contacts the inner wall of the bottom end of the feeding tube 1; Then, the motor A501 is used to drive the connected transmission disc 502 to rotate, so that the transmission disc 502 can drive the movable seat 6 connected to the guide rod 604 to rotate, and at the same time drive the brush spring steel cable 8 to rotate. Then, when the movable seat 6 rotates, the contact wheel 603 contacts the protruding block 503, and then the spring 605 is reset, so that the movable seat 6 reciprocates, thereby driving the brush spring steel cable 8 to reciprocate, so that the nylon bristles 801 can scrub; After cleaning is completed, the waste liquid is discharged by opening the valve 101, and then the motor B702 is used to drive the connected winding shaft 701 to rotate, driving the brush spring steel cable 8 to be retracted into the winding seat 7.
