Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to fig. 1 to 4, the present invention discloses an in-line heat compressor, which includes a vertically-arranged mounting frame 10, wherein a first driving source 11, a heating assembly 20 and a pneumatic clamping jaw 30 for clamping a cable 50 are arranged on the mounting frame 10.

The first driving source 11 drives the heating unit 20 to move up and down. The pneumatic gripper 30 is located on the underside of the heating assembly 20. The cable 50 is vertically arranged, a heat shrink sleeve 51 is arranged at the upper end part of the cable 50, and the pneumatic clamping jaw 30 clamps the cable 50.

Heating element 20 includes heating member 21, heat insulating material and dustcoat 24 that set gradually from inside to outside, and the holding tank that holds heat shrinkable sleeve 51 is seted up to the lower tip of heating member 21, and cable 50 is located the holding tank under. A handle 40 is provided on the mounting frame 10. The handle 40 is convenient for people to hold the on-line thermal shrinkage machine, is convenient to move and can be used anytime and anywhere.

When the heat shrinkable sleeve 51 on the cable 50 needs to be processed, the heating member 21 is preheated, the pneumatic clamping jaw 30 clamps the cable 50, and then the first driving source 11 drives the heating assembly 20 to descend, and the heat shrinkable sleeve 51 is located in the accommodating groove of the heating member 21. The heating member 21 then heats the heat shrinkable sleeve 51. And the insulation layer 22 insulates the heating member 21 from overheating of the outer cover 24. After the heating is completed, the first driving source 11 drives the heating unit 20 to ascend. The pneumatic gripper 30 releases the cable 50.

The pneumatic jaw 30 comprises a first jaw 32 and a second jaw 33, the first jaw 32 being brought into close proximity to the second jaw to effect the clamping. The first claw 32 is provided with a first stopper 34, the second claw 33 is provided with a second stopper 35, and the heat-shrinkable sleeve 51 is positioned between the first stopper 34 and the second stopper 35. The first limiting member 34 and the second limiting member 35 can limit the heat shrinkable sleeve 51. Thereby ensuring a stable structure of the heat shrinkable sleeve 51.

The first limiting part 34 includes a first semicircular arc ring, the second limiting part 35 includes a second semicircular arc ring, the first semicircular arc ring and the second semicircular arc ring are matched to form a circular limiting groove, and the heat-shrinkable sleeve 51 is arranged in the limiting groove. The circular limiting groove can better limit the heat shrinkable sleeve 51.

The heat insulation piece is a ceramic fiber heat insulation piece. The ceramic fiber insulation may better insulate the heating element 21.

A fixed cover 23 is further arranged between the outer cover 24 and the heat insulation layer 22 of the fixed cover 23, and a cavity is arranged between the fixed cover 23 and the outer cover 24. The cavity may be further insulated.

One end of the cavity is connected with the air supply device, and the other end of the cavity is connected with the exhaust device. The air supply device can be compressed air and an air inlet pipe, the compressed air continuously enters the cavity through the air inlet pipe, and original hot air in the cavity is discharged out of the cavity. The exhaust device can be an air outlet pipe which exhausts heat. Thus, heat is further dissipated by air cooling.

The heating member 21 is a hot runner. The heating member 21 may also be a resistance wire product.

The first driving source 11 is a cylinder.

The pneumatic clamping jaw 30 comprises a second driving source 31, the second driving source 31 drives the clamping jaw to move, and the second driving source 31 and the heating assembly 20 are respectively arranged on two sides of the mounting frame 10. Because the handle 40 is arranged on the mounting frame 10, the heating assembly 20 and the second driving source 31 are arranged on two sides of the mounting frame 10, so that the structure is more stable, the center of the thermal shrinkage machine falls on the accessory of the mounting frame 10, and the thermal shrinkage machine is convenient to take by using the handle 40.
