Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a drying device for the production of cable protection pipes. Background Technology

[0002] Cable protection pipes are metal protective tubes with a certain mechanical strength, laid on the outer layer of cables to prevent damage. They are mainly installed at intersections where communication cables and power lines cross, preventing short circuits caused by power line breaks that could electrify communication cables and steel ropes. This protects cables, switches, circuit boards, and even the entire device from burning out. They also provide some isolation against magnetic field interference from power lines. After production, cable protection pipes need to be cooled by water spraying and their surface moisture needs to be dried. To better dry the surface of cable protection pipes, a drying device for cable protection pipe production is proposed.

[0003] For example, the drying device for producing cable protection pipes disclosed in the authorization announcement number CN222528275U includes a base plate, a fixed frame, a movable frame, a fixed plate, a movable plate, a pipe body fixing assembly, a pipe body rotation drive assembly, a pipe body distance adjustment assembly, and a drying adjustment assembly;

[0004] Although it achieves multiple sets of pipe fixing components, facilitating the fixing of multiple sets of cable protection pipes and thus enabling simultaneous drying of multiple sets of cable protection pipes, thereby improving the drying efficiency of cable protection pipes; through the use of pipe rotation drive components, the cable protection pipes are driven to rotate during the drying process, reducing the labor intensity of workers and further improving the drying efficiency of cable protection pipes; through the use of pipe distance adjustment components, the distance between the fixed plate and the moving plate can be adjusted, making the equipment suitable for fixing cable protection pipes of different sizes, thereby improving the applicability of the equipment;

[0005] However, the existing drying device does not solve the problem that it is not convenient to use the bidirectional linkage clamping and conveying protection tube and the reciprocating swing blowing drying protection tube, which is not conducive to multi-position blowing drying of the protection tube and increasing the contact area between the drying gas and the protection tube, thus affecting the drying efficiency of the protection tube.

A cylinder is installed on the outer wall of the drying cylinder, and a push arm is installed at the output end of the cylinder. A slip ring is installed at the end of the push arm away from the cylinder, and the slip ring is slidably connected to the drying cylinder. Multiple sets of long linkage arms are arranged at equal intervals on the outer wall of the slip ring. Each long linkage arm has a hinge shaft at its end near the slip ring, and the long linkage arm is movably connected to the slip ring via the hinge shaft. Each long linkage arm has a short linkage arm at its end away from the slip ring, and a linkage shaft is installed at the end of each short linkage arm near the long linkage arm, and the short linkage arm is movably connected to the long linkage arm via the linkage shaft. An air jet pipe is fixedly installed at the end of each short linkage arm away from the long linkage arm, and the air jet pipe is movably connected to the drying cylinder.

[0008] Preferably, a drive motor is installed on the outer wall of the placement platform, and a bidirectional lead screw is installed at the output end of the drive motor, and the bidirectional lead screw is movably connected to the placement platform.

[0009] Preferably, the surface of the bidirectional lead screw is fitted with two sets of threaded sleeves, and the threaded sleeves are threadedly connected to the bidirectional lead screw.

[0010] Preferably, each of the threaded sleeves is provided with a swing arm at its top end, and each swing arm is provided with a connecting shaft at the end near the threaded sleeve, and the swing arm is movably connected to the threaded sleeve through the connecting shaft.

[0011] Preferably, each swing arm has a movable shaft at its center, and the swing arm is movably connected to the placement platform through the movable shaft.

[0012] Preferably, a clamping motor is provided at the end of the swing arm away from the threaded sleeve, and the clamping motor is fixedly connected to the swing arm.

[0014] Preferably, each surface of the drive shaft is provided with a clamping roller, and the clamping roller is fixedly connected to the drive shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the drying device not only realizes convenient bidirectional linkage clamping and conveying of the protective tube and reciprocating swing blowing drying of the protective tube, which facilitates multi-position blowing drying of the protective tube and increases the contact area between the drying gas and the protective tube, but also improves the drying efficiency of the protective tube.

[0016] (1) By placing the protective tube to be dried between two sets of clamping rollers, the drive motor drives the bidirectional screw to rotate, the bidirectional screw drives the two sets of threaded sleeves to move away from each other, the threaded sleeve drives the swing arm to rotate around the movable shaft through the connecting shaft, the swing arm drives the clamping motor, drive shaft and clamping rollers to move closer to each other, and the clamping rollers contact the outer wall of the protective tube, the two sets of clamping rollers clamp the protective tube, the clamping motor drives the clamping rollers to rotate through the drive shaft, the two sets of clamping rollers rotate in opposite directions, and the protective tube moves under the mutual cooperation of the two sets of clamping rollers. When the protective tube moves into the air drying cylinder, the external air source is connected to the flexible hose, the external drying gas is delivered to the air jet pipe through the flexible hose and sprayed out to the surface of the protective tube to dry the protective tube by blowing air. This realizes convenient bidirectional linkage clamping and conveying of the protective tube, which facilitates the air drying of the protective tube in multiple positions.

[0017] (2) The cylinder drives the push arm to move, the push arm drives the slip ring to slide on the outer wall of the drying tube, the slip ring drives the long linkage arm to rotate through the hinge shaft, the long linkage arm drives the short linkage arm to rotate through the linkage shaft, and the short linkage arm drives the jet pipe to rotate. Because the jet pipe is designed to be curved, the air delivery direction of the jet pipe can be changed. At the same time, under the reciprocating switch action of the cylinder, the jet pipe can be driven to swing and blow air to dry the protective tube, thereby improving its drying efficiency. This realizes convenient reciprocating swing blowing and drying of the protective tube, which facilitates increasing the contact area between the drying gas and the protective tube and improving the drying efficiency of the protective tube.

Each short linkage arm 7 is fixedly installed with a jet pipe 6 at the end away from the long linkage arm 16, and the jet pipe 6 is movably connected to the air drying cylinder 3. Each jet pipe 6 is installed with a flexible hose 5 at the end away from the air drying cylinder 3.

[0026] The protective tube to be dried is placed between two sets of clamping rollers 4. The drive motor 11 is turned on, which drives the bidirectional lead screw 8 to rotate. With the bidirectional lead screw 8 threadedly connected to the threaded sleeve 10, the bidirectional lead screw 8 drives the two sets of threaded sleeves 10 to move away from each other. The threaded sleeves 10 drive the swing arm 19 to rotate around the movable shaft 9 via the connecting shaft 21. The swing arm 19 drives the clamping motor 18, drive shaft 20, and clamping rollers 4 to move closer together, so that the clamping rollers 4 contact the outer wall of the protective tube. The two sets of clamping rollers 4 clamp the protective tube. Then the clamping rollers are turned off. The clamping motor 18 drives the clamping rollers 4 to rotate via the drive shaft 20. The two sets of clamping rollers 4 rotate in opposite directions. With the cooperation of the two sets of clamping rollers 4, the protective tube is moved. When the protective tube moves into the air drying tube 3, the external air source is connected to the flexible hose 5. The external drying gas is delivered to the jet pipe 6 through the flexible hose 5 and sprayed out onto the surface of the protective tube to dry it. This realizes convenient bidirectional linkage clamping and conveying of the protective tube, which facilitates multi-position air drying of the protective tube.

[0027] A drive motor 11 is installed on the outer wall of the placement platform 1. The drive motor 11 plays the role of power drive. A bidirectional lead screw 8 is installed at the output end of the drive motor 11, and the bidirectional lead screw 8 is movably connected to the placement platform 1.

[0028] Two sets of threaded sleeves 10 are fitted on the surface of the bidirectional lead screw 8, and the threaded sleeves 10 are threadedly connected to the bidirectional lead screw 8. Each threaded sleeve 10 has a swing arm 19 at its top end, and each swing arm 19 has a connecting shaft 21 at one end near the threaded sleeve 10.

[0031] When cylinder 12 is opened, it drives push arm 13 to move. Push arm 13 drives slip ring 14 to slide on the outer wall of drying cylinder 3. Slip ring 14 drives long linkage arm 16 to rotate through hinge shaft 15. Long linkage arm 16 drives short linkage arm 7 to rotate through linkage shaft 17. Short linkage arm 7 drives jet pipe 6 to rotate. Because jet pipe 6 is curved, the air delivery direction of jet pipe 6 can be changed. At the same time, under the reciprocating switch action of cylinder 12, jet pipe 6 can be driven to swing and blow air to dry the protective tube, thereby improving its drying efficiency. This realizes convenient reciprocating swing blowing to dry the protective tube, which facilitates increasing the contact area between the drying gas and the protective tube and improves the drying efficiency of the protective tube.

[0032] Working principle: The protective tube to be dried is placed between two sets of clamping rollers 4. The drive motor 11 drives the bidirectional lead screw 8 to rotate, which in turn drives the two sets of threaded sleeves 10 to move away from each other. The threaded sleeves 10 drive the swing arm 19 to rotate around the movable shaft 9 via the connecting shaft 21. The swing arm 19 drives the clamping motor 18, drive shaft 20, and clamping rollers 4 to move closer together, bringing the clamping rollers 4 into contact with the outer wall of the protective tube. The two sets of clamping rollers 4 clamp the protective tube. The clamping motor 18 drives the clamping rollers 4 to rotate via the drive shaft 20. The two sets of clamping rollers 4 rotate in opposite directions. With the cooperation of the two sets of clamping rollers 4, the protective tube moves. When the protective tube moves into the air drying cylinder 3, the external air source is connected to the flexible hose 5. Drying gas is delivered through flexible hose 5 into jet pipe 6 and sprayed from jet pipe 6 onto the surface of protective pipe to dry it. Cylinder 12 drives push arm 13 to move, and push arm 13 drives slip ring 14 to slide on the outer wall of drying cylinder 3. Slip ring 14 drives long linkage arm 16 to rotate through hinge shaft 15. Long linkage arm 16 drives short linkage arm 7 to rotate through linkage shaft 17. Short linkage arm 7 drives jet pipe 6 to rotate. Because jet pipe 6 is curved, the air delivery direction of jet pipe 6 can be changed. At the same time, under the reciprocating switch action of cylinder 12, jet pipe 6 can be driven to swing and blow air to dry the protective pipe, thereby improving its drying efficiency. The above is the complete usage of the drying device for cable protection pipe production.
