[0017] The beneficial effects of the present utility model are as follows: The present utility model uses a plurality of coating cylinders surrounding the cable to perform coating processing on the cable, which can ensure uniform coating and good coating effect. The coating cylinders are arranged on a rotating disk, and the rotating disk is driven by a first driving motor to rotate, so that the coating cylinders can rotate around the cable to ensure that the surface of the cable is fully coated with the coating. And due to the rotation of the plurality of coating cylinders, the coating spheres of each coating cylinder sequentially coat the cable, which not only ensures the uniformity of the coating, but also has a smoothing effect to ensure the appropriate thickness of the coating on the surface of the cable.

[0018] Each coating cylinder is arranged in a through groove of the rotating disk and is matched with an adjusting disk arranged on the side of the rotating disk through a moving column on the side.

The adjusting disk also has a limiting function, which can fix the relative position of the coating cylinder and the rotating disk to prevent the coating cylinder from moving under the action of centrifugal force when the rotating disk rotates, thereby affecting the coating effect.

[0019] An installation base is arranged on the fixed base, and a pull rod and a filling head are arranged on the installation base. When the coating agent in the coating cylinder is used up, the moving mechanism drives the filling head and the pull rod to move towards the coating cylinder. First, the telescopic mechanism is used to make the pull rod and the electromagnet suction head at the end of the pull rod enter the interior of the coating cylinder and magnetically connect with the sealing plug, and then the sealing plug is pulled to move towards the tail end of the coating cylinder to form an injection cavity; then the filling head descends to cooperate with the injection check valve on the side of the coating cylinder to inject the coating agent into the coating cylinder. After the injection is completed, they are disengaged in sequence to avoid affecting the rotation of the rotating disk.

[0020] A movable sealing plug is arranged inside the coating cylinder, which can prevent the coating agent in the coating cylinder from overflowing from the opening at the end of the coating cylinder. At the same time, the sealing plug is connected to the coating cylinder through a spring, so that the sealing plug can move as the coating agent is used. This not only ensures a good sealing effect, but also maintains the pressure on the coating agent, preventing the coating agent from moving outward under the action of centrifugal force and affecting the coating effect.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0034] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0035] As Figure 1 and Figure 2 shown, a refractory cable production and processing device includes: a fixed base 1, the center of the fixed base 1 is open, and a rotatable rotating disk 2 is provided on one side. The opening in the center of the fixed base 1 is circular; the rotating disk 2 is circular, is concentrically arranged with the circular opening, and the rotating disk 2 is rotatable.

[0036] As Figure 5 and Figure 6 shown, a circular hole is opened in the center of the rotating disk 2, a driving gear 3 concentrically arranged therewith is fixedly connected to the first side, and an adjusting disk 4 concentrically arranged therewith is rotatably connected to the second side. The circular hole in the center of the rotating disk 2 is a round hole.

[0037] Among them, asFigure 3 As shown in the figure, a through hole corresponding to the central opening of the rotating disk 2 is provided in the center of the driving gear 3, and it is driven to rotate by a first driving motor 5 arranged on the fixed base 1. The driving gear 3 is fixedly connected to the rotating disk 2, and the two rotate synchronously. A transmission gear 31 is meshed on one side of the driving gear 3, and the transmission gear 31 is in transmission connection with the output shaft of the first driving motor 5.

[0038] As Figure 4 shown in the figure, a through hole corresponding to the central opening of the rotating disk 2 is provided in the center of the adjusting disk 4, and a rotating part 6 is provided on its second side (the side away from the rotating disk 2). The rotating part 6 has a cylindrical structure and is arranged around the circular opening in the center of the adjusting disk 4. At the same time, the rotating part extends towards the fixed base 1 to the outside of the fixed base 1, and a rotating handle 61 is provided at the end of the rotating part 6 located outside the fixed base 1. A circular through hole is also provided in the center of the rotating handle 61. The adjusting disk 4 can be manually rotated relative to the rotating disk 2 by rotating the rotating handle 61. To improve the stability of the adjusting disk 4, the rotational connection between the adjusting disk 4 and the rotating disk 2 is a damped rotational connection, that is, when rotating the adjusting disk 4, it is subject to a damping effect and a large force is required for rotation.

[0039] As Figure 5 and Figure 6 shown in the figure, a plurality of through grooves 21 are provided inside the rotating disk 2. The through grooves 21 extend outward along the diameter direction of the rotating disk 2 from the opening in the center of the rotating disk 2 until they penetrate the rotating disk 2. A slotted opening 22 is provided on one side of the through groove 21. The slotted opening 22 extends inward from the second side of the rotating disk 2 until it communicates with the through groove 21. The slotted opening 22 and the through groove 21 have the same length and both penetrate the rotating disk 2.

[0040] A coating cylinder 7 is arranged in the through groove 21, and the coating cylinder 7 slides in the through groove 21. The coating cylinder 7 is preferably a cylindrical structure and is hollow inside. A coating sphere 71 with a fixed position and capable of rotating is provided at the first end, and the second end is provided with an opening. The coating cylinder 7 can accommodate a coating agent inside, and its first end has a structure with a gradually decreasing diameter.

[0041] As Figure 7 shown in the figure, a movable sealing plug 72 is arranged inside the coating cylinder 7, and a moving column 73 and an injection check valve 74 are arranged on the outer wall. The sealing plug 72 is used to seal the barrel of the coating cylinder 7 to prevent the internal coating agent from leaking. A first spring 75 is connected to the side of the sealing plug 72 away from the first end of the coating cylinder 7. The other end of the first spring 75 extends outside the coating cylinder 7 and is connected to a retaining piece 76 arranged outside the coating cylinder 7. The first spring 75 is a spring with a cylindrical structure, and a through hole is left in its center for the following pull rod 11 to pass through. The moving column 73 and the injection check valve 74 are fixedly arranged on the same side of the coating cylinder 7, and the moving column 73 is closer to the first end of the coating cylinder 7.

[0042] Among them, the baffle 76 is circular, with an opening in the center. The opening is circular and corresponds to the central hole of the first spring 75. Further, extension parts 78 are provided on both sides of the baffle 76. The extension parts 78 extend to both sides of the coating cylinder 7 and are connected to the first end of the second spring 79. The second end of the second spring 79 is connected to the fixing piece 710 arranged on the outer peripheral surface of the coating cylinder 7, making the baffle 76 elastically cooperate with the coating cylinder 7. When there is more coating agent in the coating cylinder 7, the extrusion seal plug 72 is pushed closer to the second end of the coating cylinder 7. At this time, the first spring 75 is compressed and drives the second spring 79 to be stretched to ensure the pressure of the seal plug 72 on the coating agent. As the coating agent is used, the seal plug 72 gradually moves closer to the first end of the coating cylinder 7, and the first spring 75 gradually elongates. When the first spring 75 elongates, the pressure on the baffle 76 decreases. At this time, the baffle 76 moves closer to the coating cylinder 7 under the action of the second spring 79. If the position of the baffle 76 is fixed differently, the pressure of the seal plug 72 on the coating agent will be smaller as time goes on. Therefore, in this embodiment, the baffle 76 is elastically connected to the coating cylinder 7 through the second spring 79, so that the baffle 76 can gradually approach the coating cylinder 7 as the coating agent is used to ensure the relative constancy of the pressure of the seal plug 72 on the coating agent.

[0043] As Figure 4 and Figure 5 shown, both the moving column 73 and the injection check valve 74 extend from the slot 22 to the outside of the rotating disk 2. At the same time, the upper section of the moving column 73 is slidably fitted in the arc-shaped sliding groove 41 opened on the adjusting disk 4. The number of arc-shaped sliding grooves 41 is several, corresponding to each coating cylinder 7, and cooperating with the moving column 73 to realize the relative fixation of the position of the coating cylinder 7. When the adjusting disk 4 is rotated, the arc-shaped sliding groove 41 will drive the moving column 73 to move, and then drive the coating cylinder 7 to move along the through groove 21 to change the distance between the first ends of the coating cylinders 7 to adapt to cables of different diameters.

[0044] A connection groove 77 is provided at the central position of the side surface of the seal plug 72 away from the center of the rotating disk 2. The connection groove 77 is located at the center of the first spring 75, corresponding to the position of the central through hole of the first spring 75 and also corresponding to the opening at the center of the baffle 76, so that the external pull rod 11 can extend into the coating cylinder 2 to be connected to the seal plug 72.

[0045] The rotating disk 2 is rotatably connected to the fixed base 1 through a rotating connection cylinder 13. The rotating connection cylinder 13 is in a cylindrical structure and is arranged around the outside of the adjusting disk 4. The rotating connection cylinder 13 includes two rotatable parts, one part is connected to the fixed base 1, and the other part is connected to the rotating disk 2. The injection check valve 74 is located outside the rotating connection cylinder 13 for the filling head 10 to cooperate.

[0046] As Figure 1 and Figure 2 shown, mounting bases 8 are provided on the fixed base 1. The number of mounting bases 8 is several, corresponding to each coating cylinder 7.

[0047] As shown in Figure 8 and Figure 9 shown, a sliding base 9 is slidably arranged on the side of the mounting base 8, and the sliding base 9 is driven by a moving mechanism to move in a direction close to or away from the coating cylinder 7. Among them, the moving mechanism includes a lead screw 81, and the lead screw 81 is rotatably arranged on the mounting base 8 and is driven to rotate by a second driving motor 82 arranged on the mounting base 8. A sliding connection part 92 is arranged on the sliding base 9, and the sliding connection part 92 is in threaded fit connection with the lead screw 81. The lead screw 81 drives the sliding connection part 92, that is, the sliding base 8, to move.

[0048] A liftable filling head 10 is arranged at the first end of the sliding base 9, and a telescopic pull rod 11 is arranged at the second end. An electromagnet suction head 12 is arranged at the end of the pull rod 11, and the electromagnet suction head 12 is adapted to the connecting groove 77 to realize the magnetic attraction connection between the pull rod 11 and the sealing plug 72. The filling head 10 is adapted to the injection check valve 74 and can be docked to inject the coating agent into the coating cylinder 7.

[0049] Specifically, as shown in Figure 8 shown, the sliding base 9 is of an L-shaped structure, and the L-shaped structure is divided into a horizontal arm and a vertical arm. The filling head 10 is arranged at the end of the horizontal arm, the pull rod 11 is arranged at the bottom end of the vertical arm, and at the same time, the sliding connection part 92 is located in the middle of the vertical arm.

[0050] More specifically, as shown in Figure 10 shown, the filling head 10 is lifted and lowered through a lifting mechanism. The lifting mechanism includes a bottom plate 101, the bottom plate 101 is fixed to the end of the horizontal arm, a lifting cylinder 102 is arranged on the bottom plate 101, a sliding block 103 that is slidably matched with the bottom plate 101 is connected to the end of the piston rod of the lifting cylinder 102, and the filling head 10 is connected to the sliding block 103. The filling head 10 is lifted and lowered by the lifting cylinder 102 to realize its cooperation with the injection check valve 74. At the same time, the pull rod 11 is telescoped through a telescoping mechanism. The telescoping mechanism includes a telescoping cylinder 111, the telescoping cylinder 111 is fixed to the bottom end of the vertical arm, and its piston rod is connected to the pull rod 11 to drive the pull rod 11 to move, so that the pull rod 11 can enter the coating cylinder 7.

[0051] A butting rod 91 is arranged on the sliding base 9. The butting rod 91 is arranged below the horizontal arm and can butt against a butting platform 23 arranged on the outer peripheral surface of the rotating disk 2 to limit the moving position of the sliding base 9 and facilitate positioning.

[0052] Coating process: The cable 100 passes through the central opening of each structure, and the adjustment disk 4 drives each coating cylinder 7 to move, so that the coating ball 71 contacts the surface of the cable 100. The cable 100 moves forward, and at the same time, the first drive motor 5 drives the drive gear 3 and the rotating disk 2 to rotate, and the rotating disk 2 drives the coating cylinder 7 to rotate, so that the coating agent is evenly coated on the surface of the cable 100.

[0053] Filling process: When the coating agent in the coating cylinder 7 is used up, the rotating disk 2 and each coating cylinder 7 are rotated to the set position. Then the second drive motor 82 drives the screw rod 81 to rotate, and the screw rod 81 drives the sliding base 9 to move forward until the abutment rod 91 abuts on the abutment platform 23. At this time, the filling head 10 is facing the injection check valve 74, and the pull rod 11 is facing the coating cylinder 7. After that, the telescopic cylinder 111 works, driving the pull rod 11 and the electromagnet suction head 12 to move, and after passing through the opening in the center of the baffle 76 and the internal through hole of the first spring 75 in turn, the electromagnet suction head 12 is inserted into the connecting groove 77 on the sealing plug 72, and the power is turned on to realize the magnetic connection, and then the telescopic cylinder 111 retracts, so that the pull rod 11 drives the sealing plug 72 to move toward the second end of the coating cylinder 7, so that there is an injection cavity in the coating cylinder 7. Maintaining magnetic attraction, the upgrading cylinder 102 drives the filling head 10 to descend so that it cooperates with the injection check valve 74 and injects the coating agent. After the injection is completed, the filling head 10 is disengaged first, and then the pull rod 11 is disengaged, and the sliding base 9 returns to its original position.
