Description

Technical Field

[0001] The invention relates to the technical field of cable head sealing, in particular to an automatic heat shrink capping device. Background Art

[0002] Cable heads are crucial components in power engineering, widely used in industrial and civil construction cable lines. During shipment, transportation, and storage, cable heads must be sealed to prevent moisture from entering the exposed cable heads and degrading the cable's insulation.

Although existing capping devices can automatically seal cables, in actual use, workers usually fix the cable and the cap, then start a hot air blower to blow on the cap to melt the hot melt adhesive inside the cap and bond the cap to the cable. However, this method makes it difficult to evenly heat the hot melt adhesive on the inner wall of the cap, thereby reducing the bonding effect between the cap and the cable, and the sealing effect after sealing is poor.

[0051] The rotating mechanism includes a circular shaft 5 and a driving device 7;

[0052] The round shaft 5 is arranged in the interior of the frame 3 in a rotating mode;

[0053] The round shaft 5 is in a tubular structure, and the cable is extended into the interior of the round shaft from one end (i.e. the cable extension end) of the round shaft 5, and the cap is extended out from the other end (i.e. the cable extension end) of the round shaft 5;

When the automatic heat shrink cap device is used to seal the cable head, the cable can be first placed in the interior of the round shaft 5, and the cable is fixed by the clamping mechanism, and then the cap is sleeved on the end of the cable extending out of the round shaft 5; then the heating device is started to heat the position of the cable sleeved with the cap; finally, the driving device 7 is started to rotate the lead screw 8, the rotation of the lead screw 8 drives the moving block 9 to move the sliding block 10 to the cable extension end or to the cable extension end of the round shaft 5, the sliding block 10 extrudes the inner wall of the arc-shaped slot 6 on the round shaft 5, the round shaft 5 drives the cable fixed by the clamping mechanism to rotate, the sleeved cap rotates with the cable, the heat adhesive on the cap and the inner wall of the cap is uniformly heated under the heating of the heating device, the adhesion effect of the cap and the cable is improved, and the sealing effect after the cap is better.

[0060] It should be noted that the driving device 7 is a driving device which drives in a rotating mode, and is preferably a brake motor; the heating mechanism is preferably a hot air heating mechanism, and the air outlets can be arranged in multiple directions at the cap, and hot air streams are blown out in multiple directions to heat the cap more fully; specifically, Figures 1 to 2As shown, a table 2 is provided at the bottom of the frame 3, and a plurality of brackets 1 are provided at the bottom of the table 2; a universal wheel 21 can be installed at the bottom end of the bracket 1, and the universal wheel 21 corresponding to each bracket 1 has the same size.

[0061] In a preferred embodiment, the clamping mechanism includes a first lifting device 11, a lifting frame 12, a clamping block 13 and a round block 15;

[0062] The first lifting device 11 is fixedly mounted on the outer surface of the circular shaft 5;

[0063] The outer surface of the circular shaft 5 is provided with two movable holes penetrating into the interior;

[0064] There are two clamping blocks 13, and the two clamping blocks 13 are movably mounted on the circular shaft 5 through the two movable holes;

[0065] The clamping block 13 is provided with a through hole 14 on the portion outside the circular shaft 5, and the through hole 14 is arranged obliquely relative to the depth direction of the movable hole;

[0066] The lifting frame 12 is in a Π shape and includes two vertical frames and a horizontal frame. The horizontal frame of the lifting frame 12 is fixedly connected to the output end of the first lifting device 11;

[0067] One end of the round block 15 is fixedly mounted on the bottom of the vertical frame, and the other end of the round block 15 extends into the through hole 14 .

[0068] It should be noted that the first lifting device 11 can be a linear motor, an electric push rod, a cylinder or other device that transmits in a linear motion, preferably an electric push rod; the round block 15 is slidably connected to the through hole 14; the side of the clamping block 13 that extends into the round shaft 5 and contacts the cable is preferably an arc surface and is roughened, which can enhance the clamping effect of the clamping block 13 on the cable.

[0069] Specifically, if Figure 5As shown, the movable hole is opened in the part of the circular shaft 5 near the cable extension end, and the two movable holes are evenly distributed along the circumferential direction of the circular shaft 5. The depth direction of the movable hole is perpendicular to the lifting direction of the lifting frame 12; the through hole 14 is inclined relative to the depth direction of the movable hole, and can be inclined in the direction of the lifting frame 12 descending or in the direction of the lifting frame 12 ascending; if the through hole 14 is inclined relative to the depth direction of the movable hole and in the direction of the lifting frame 12 descending, by starting the output end of the first lifting device 11 to descend, the lifting frame 12 can be moved downward, thereby causing the round block 15 to move downward to squeeze the through hole 1 4, thereby causing the two clamping blocks 13 to move toward each other to clamp and fix the cable. Conversely, by starting the output end of the first lifting device 11 to rise, the two clamping blocks 13 can release the cable. If the through hole 14 is inclined relative to the depth direction of the movable hole and in the direction of the lifting frame 12 rising, by starting the first lifting device 11 to rise, the lifting frame 12 can be moved upward, thereby causing the round block 15 to move upward to squeeze the inner wall of the through hole 14, thereby causing the two clamping blocks 13 to move toward each other to clamp and fix the cable. Conversely, by starting the output end of the first lifting device 11 to descend, the two clamping blocks 13 can release the cable.

[0070] In a preferred embodiment, the heating mechanism includes a hot air blower 16, an air inlet pipe 17 and an exhaust pipe 18;

[0071] The hot air blower 16 is fixedly mounted on the top of the frame 3 near the cable extension end of the circular shaft 5;

[0073] The exhaust pipe 18 is fixedly installed at the bottom of the hot air blower 16. The exhaust pipe 18 passes through the frame 3. The air outlet at the bottom end of the exhaust pipe 18 faces the sealing cap, that is, the cable extending end of the circular shaft 5.

[0074] It can be understood that by starting the hot air blower 16, the air inlet pipe 17 can draw in external air, convert it into hot air flow and then spray it downward from the exhaust pipe 18, thereby heating the sealing cap, causing the sealing cap to shrink and the hot melt adhesive on the inner wall of the sealing cap to melt, and the sealing cap to be bonded to the outside of the cable.

[0075] In a preferred embodiment, the automatic heat shrink capping device provided by the present invention further includes an anti-falling mechanism, which includes a second lifting device 19 and a baffle 20;

[0076] The baffle 20 is fixedly connected to the output end of the second lifting device 19;

[0077] The second lifting device 19 is installed next to the sealing cap, specifically, it can be installed on the table 2 near the cable extension end of the circular shaft 5; when the output end of the second lifting device 19 is at the maximum stroke position, the baffle faces the bottom surface of the sealing cap, that is, the cable extension end of the circular shaft 5.

[0078] It can be understood that by starting the second lifting device 19, the baffle 20 can be moved upward. When the baffle 20 moves to the highest position, the sealing cap can be covered to prevent the sealing cap from falling off the cable head during the rotation of the cable, resulting in failure of cable sealing. The baffle 20 can be square; the side of the baffle 20 facing the bottom of the sealing cap is smoothed to reduce the friction between it and the sealing cap, preventing the sealing cap and the cable from rotating due to friction between the sealing cap and the baffle 20, resulting in relative rotation between the sealing cap and the cable, affecting the normal sealing work.
