DETAILED DESCRIPTION

[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 the embodiments.

[0022] Reference Figure 1-4 A high-efficiency rubber oil pipe production auxiliary material feeding device includes a mounting plate 1 and a servo motor 2. A first support rod 3 and a second support rod 4 are fixedly installed on the top of the mounting plate 1. A support block 5 and a round tube 6 are fixedly installed on the top of the first support rod 3 and the second support rod 4 respectively. The servo motor 2 is fixedly installed on the support block 5, wherein scale lines are arranged on the outer wall of the round tube 6. Specifically, by setting the scale lines, the feeding amount can be intuitively observed.

[0023] A push plate 7 is slidably provided in the circular tube 6, a fixed plate 8 is fixedly installed in the circular tube 6, and a drainage mechanism is provided on the fixed plate 8. The driving shaft of the servo motor 2 is fixedly connected to a threaded rod 9, and the free end of the threaded rod 9 is fixedly connected to a driven rod 10 provided with a rotating seal penetrating the side wall of the circular tube 6. The free end rotating seal of the driven rod 10 penetrates the push plate 7 and the fixed plate 8, and a rotating block 11 is fixedly installed at the free end of the driven rod 10. By opening the ball valve, the additive is transported into the circular tube 6 through the connecting pipe 18. When the space between the push plate 7 and the fixed plate 8 is filled, the ball valve can be closed, and then the servo motor 2 is started. The driving shaft of the servo motor 2 drives the threaded rod 9 to rotate, and the threaded rod 9 causes the internal thread block 16 to slide thereon, and the internal thread block 16 drives the push plate 7 to move through the connecting plate 33 and the fixed rod 17.

[0024] Among them, the additive flows into the circular tube 6 on the right side of the fixed plate 8. At the same time, when the threaded rod 9 drives the internal threaded block 16 to move, the threaded rod 9 will also drive the driven rod 10 to rotate, and the driven rod 10 drives the rotating block 11 to rotate, thereby achieving the purpose of grinding the additive flowing through the rotating block 10 and the inner wall of the circular tube 6.

[0025] The driven rod 10 and the rotating block 11 are respectively provided with an air guide hole 12 and a chamber 13, and a through hole 14 is provided on the side wall of the air guide hole 12;

[0026] A sliding mechanism is provided through the sliding seal on the side wall of the chamber 13, a through opening 15 is provided between the air guide hole 12 and the chamber 13, an internal thread block 16 is threadedly sleeved on the threaded rod 9, and two adjustment mechanisms are slidably provided on the round tube 6, both of which are fixedly connected to the internal thread block 16, a fixed rod 17 provided through the side wall of the round tube 6 is provided with a sliding seal between the adjustment mechanism and the push plate 7, a connecting pipe 18 is provided on the top of the round tube 6, wherein a ball valve is provided on the connecting pipe 18, specifically, for connecting and closing the connecting pipe 18, a feeding port 19 is opened on the side wall of the round tube 6, and a sealing block 20 fixedly connected to the sliding mechanism is slidably provided in the feeding port 19.

[0027] Among them, the discharge mechanism includes a discharge port 21 opened on the fixed plate 8 and two limit rods 22 fixedly installed on the side wall of the fixed plate 8, a blocking block 23 is provided in the discharge port 21 for sliding sealing, the free ends of the two limit rods 22 are fixedly installed with the same limit plate 24, a telescopic rod 25 is fixedly connected between the limit plate 24 and the blocking block 23, and a first return spring 26 slidably sleeved on the telescopic rod 25 is fixedly connected between the limit plate 24 and the blocking block 23.

[0028] It should be noted that, when the push plate 7 moves to the right, the push plate 7 will squeeze the additive between it and the fixed plate 8. Due to the pressure, the blocking block 23 slides in the drain port 21 on the fixed plate 8, so that it slides out of the drain port 21, thereby achieving the purpose of discharging the additive between the push plate 7 and the fixed plate 8. At this time, the telescopic rod 25 is retracted and the first return spring 26 is compressed. When the push plate 7 moves to fit with the fixed plate 8, the additive can be completely discharged. At this time, the first return spring 26 in a compressed state drives the blocking block 23 to reset, and the blocking block 23 moves to the drain port 21.

[0029] Among them, the sliding mechanism includes a sliding block 27 arranged in a sliding seal that passes through the chamber 13, the sliding block 27 is fixedly connected to the sealing block 20, and a sliding plate 28 is provided in the sliding seal in the chamber 13, one side of the sliding plate 28 is fixedly connected to the sliding block 27, and a second return spring 29 is fixedly connected between the other side of the sliding plate 28 and the inner wall of the chamber 13, and further, a connecting rod 30 is fixedly connected between the sliding block 27 and the sealing block 20.

[0030] It should be noted that when the sliding plate 28 slides to the left in the chamber 13, the sliding plate 28 drives the sliding block 27 to move to the left, and the sliding block 27 drives the sealing block 20 to move to the left through the connecting rod 30, so that the feeding port 19 is in an open state, thereby achieving the purpose of feeding. When the sliding plate 28 moves to the right, the purpose of closing the feeding port 19 is achieved, thereby not affecting the production of the rubber oil pipe.

[0031] Furthermore, in the process of the push plate 7 moving toward the fixed plate 8, since the internal space of the circular tube 6 on the left side of the push plate 7 becomes larger, the interior of the circular tube 6 on the left side of the push plate 7 is in a negative pressure state, so that the air guide hole 12 is in a negative pressure state, so that the sliding plate 28 slides to the left in the chamber 13, so that the sliding plate 28 drives the sliding block 27 to move to the left, and the sliding block 27 drives the sealing block 20 to move to the left through the connecting rod 30, so that the loading port 19 is in an open state, thereby achieving the purpose of loading.

[0032] Furthermore, after the loading is completed, the servo motor 2 is reversed to reset the push plate 7, so that the pressure inside the circular tube 6 on the left side of the push plate 7 is restored to its original state. At this time, the pressure inside the chamber 13 is also restored to its original state, and the sliding plate 28 is reset by the second reset spring 29 in a compressed state, so that the sliding block 27 drives the sealing block 20 to move through the connecting rod 30, so that the loading port 19 is closed.

[0033] The adjustment mechanism includes an alignment plate 31 slidably arranged on the circular tube 6 , a movable plate 32 is fixedly connected to the side wall of the alignment plate 31 , the movable plate 32 is fixedly connected to the internal thread block 16 with a connecting plate 33 , and the connecting plate 33 is fixedly connected to the fixing rod 17 .

[0034] It should be noted that the threaded rod 9 drives the internal thread block 16 to move, and the internal thread block 16 drives the alignment plate 31 to move through the connecting plate 33 and the moving plate 32, thereby achieving the purpose of adjusting the feeding amount.

[0035] Furthermore, the inner cross-sectional area of ​​the circular tube 6 is a constant S1, the outer cross-sectional area of ​​the driven rod 10 is a constant S2, and the distance between the push plate 7 and the fixed plate 8 is a variable H. Thus, we can derive the volume change equation between the push plate 7 and the fixed plate 8 as: V=(S1-S2)*H, so that the amount of additive can be adjusted according to the volume change, which can be directly expressed by the scale line.

[0036] In the present invention, by opening the ball valve and conveying the additive into the circular tube 6 through the connecting pipe 18, when the space between the push plate 7 and the fixed plate 8 is filled, the ball valve can be closed, and then the servo motor 2 is started, and the driving shaft of the servo motor 2 drives the threaded rod 9 to rotate, and the threaded rod 9 causes the internal thread block 16 to slide thereon, and the internal thread block 16 drives the push plate 7 to move through the connecting plate 33 and the fixed rod 17.

[0037] Thereby, the push plate 7 will squeeze the additive between it and the fixed plate 8. Due to the pressure, the blocking block 23 will slide in the discharge port 21 on the fixed plate 8, so that it slides out of the discharge port 21, thereby achieving the purpose of discharging the additive between the push plate 7 and the fixed plate 8. At this time, the telescopic rod 25 is retracted, and the first return spring 26 is compressed. When the push plate 7 moves to fit with the fixed plate 8, the additive can be completely discharged. At this time, the first return spring 26 in a compressed state drives the blocking block 23 to reset, and the blocking block 23 moves to the discharge port 21.

[0038] At this time, the additive flows into the circular tube 6 on the right side of the fixed plate 8. At the same time, when the threaded rod 9 drives the internal threaded block 16 to move, the threaded rod 9 will also drive the driven rod 10 to rotate, and the driven rod 10 will drive the rotating block 11 to rotate, thereby achieving the purpose of grinding the additive flowing through the rotating block 10 and the inner wall of the circular tube 6.

[0039] During the movement of the push plate 7 toward the fixed plate 8, the internal space of the circular tube 6 on the left side of the push plate 7 becomes larger, so that the interior of the circular tube 6 on the left side of the push plate 7 is in a negative pressure state, so that the air guide hole 12 is in a negative pressure state, so that the sliding plate 28 slides to the left in the chamber 13, so that the sliding plate 28 drives the sliding block 27 to move to the left, and the sliding block 27 drives the sealing block 20 to move to the left through the connecting rod 30, so that the loading port 19 is in an open state, thereby achieving the purpose of loading.

[0040] After the loading is completed, the servo motor 2 is reversed to reset the push plate 7, so that the pressure inside the circular tube 6 on the left side of the push plate 7 is restored to its original state. At this time, the pressure inside the chamber 13 is also restored to its original state, and the sliding plate 28 is reset by the second reset spring 29 in a compressed state, so that the sliding block 27 drives the sealing block 20 to move through the connecting rod 30, so that the loading port 19 is closed.

[0041] By controlling the servo motor 2 to rotate, the threaded rod 9 drives the internal thread block 16 to move, and the internal thread block 16 drives the alignment plate 31 to move through the connecting plate 33 and the moving plate 32, thereby achieving the purpose of adjusting the feeding amount.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
