Description

Technical Field

[0001] The utility model belongs to the technical field related to cable processing, in particular to a heat shrink device for a cable sleeve. Background Art

[0002] The cable sheath is a device used to protect the cable. The cable sheath is usually the outermost layer of the cable, and most of them are made of rubber materials, etc., used to protect the cable core and other structures, and have anti-corrosion and moisture-proof properties. After the cable sheath is set on the outer layer of the cable core, it usually needs to be shrunk by a heat shrink process to tightly adhere to the outer layer of the cable core. However, there are still the following disadvantages in the actual heat shrink operation:

[0003] 1. Conventional cable sheath heat shrinkage processing is mostly carried out in the open air, using the heat of various heating equipment to heat the cable sheath so that it shrinks and adheres to the outer layer of the cable core. However, in the open air, there is no narrow space, whether indoors or outdoors, which leads to more heat loss and low heat shrinkage efficiency.

[0004] 2. The cable core and cable sheath are usually in a loose state before heat shrinkage. If the position is not centered during heat shrinkage, it is easy to cause uneven heating or even local overheating, which may damage the cable sheath and lack a certain supporting structure;

[0005] 3. Secondly, conventional heat shrink devices may only locally concentrate heat and shrink, and the overall heat distribution is uneven, resulting in inconsistent heat shrinkage. Utility Model Content

[0006] The utility model aims to provide a heat shrink device for a cable sheath, which solves the problems of large heat loss, low heat shrink efficiency, lack of auxiliary supporting structure and uneven heat distribution during heat shrinkage of the cable sheath by arranging a processing box, a dustproof and heat-insulating curtain, a ball bearing, a heating sheath and an electric heating tube.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a heat shrink device for a cable sheath, comprising a processing box, a dustproof and heat-insulating curtain and a heating sleeve, wherein an inlet and an outlet are respectively provided at both ends of the processing box, and the inlet and the outlet are communicated with the inner cavity of the processing box, and dustproof and heat-insulating curtains are provided at both ends of the processing box outside the inlet and the outlet;

[0009] Two symmetrical tubular heating jackets are arranged inside the processing box, and spiral electric heating tubes are fixed on the inner walls of the heating jackets;

[0010] The inner walls of the inlet and the outlet are both embedded with rolling balls distributed in a ring array.

[0011] Furthermore, the dustproof and heat-insulating curtain comprises a horizontal bar fixed to the end of the processing box, and the bottom end of the horizontal bar is fixed with curtains distributed at equal intervals, and the bottom end of the curtains is lower than the position of the inlet and the outlet.

[0012] Furthermore, two groups of symmetrically distributed connecting rods are fixed to the outer peripheries of the two heating sleeves, and one end of the connecting rod away from the heating sleeve is fixedly connected to the inner wall of the processing box.

[0013] Furthermore, the two heating jackets are respectively close to the outlet and the inlet, and the inner diameters of the heating jackets and the electric heating tubes are larger than the inner diameters of the inlet and the outlet.

[0014] Furthermore, a controller is fixed on the outer side wall of the processing box, and the electrical control end of the controller is electrically connected to the electrical input end of the electric heating tube.

[0015] Furthermore, the cable core and the cable sheath are guided out after passing through the inlet, two heating sheaths and the outlet in sequence, and the outer wall of the cable sheath contacts the lowest ball.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model solves the problem of large heat loss and low heat shrinkage efficiency when the cable sheath is heat-shrunk by arranging a processing box, a dust-proof and heat-insulating curtain, and a heating sleeve. When the cable sheath is heat-shrunk, the conventional open-air heat shrinkage processing process is changed, and the heating sleeve is placed in the processing box. A large amount of heat generated by the electric heating tube in the heating sleeve is retained in the processing box, and the dust-proof and heat-insulating curtain covers the inlet and outlet positions of the processing box to reduce heat loss as much as possible and increase its heat shrinkage efficiency. When the cable sheath passes through the electric heating tube, the cable sheath is heated to shrink and adhere to the outside of the cable core, so that the overall heat loss is small and the cost is reduced.

[0018] 2. The utility model solves the problem of lack of auxiliary support structure when the cable sheath is heat-shrunk by providing a processing box and balls; the cable core and the cable sheath pass through the inlet, pass through two heating sleeves and then are led out from the outlet, and balls are provided in both the inlet and the outlet to assist the supporting movement of the cable sheath, facilitate the movement, and maintain the cable core and the cable sheath in the center, so that when passing through the heating sleeve, they can fully receive the heat of the electric heating tube, which is convenient for heat shrinkage treatment.

[0019] 3. The utility model solves the problem of uneven heat distribution during heat shrinkage by arranging a heating sleeve and an electric heating tube; the heating sleeve is a tubular structure, and a spiral electric heating tube is arranged on its inner wall. When the cable sleeve passes through, a surrounding heat shrinkage treatment is performed on it, which is more uniform and comprehensive. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1-5 As shown, the utility model is a heat shrink device for a cable sleeve, comprising a processing box 1, a dustproof and heat-insulating curtain 2 and a heating sleeve 3. An inlet 103 and an outlet 104 are respectively provided at both ends of the processing box 1, and the inlet 103 and the outlet 104 are communicated with the inner cavity of the processing box 1, and dustproof and heat-insulating curtains 2 are provided at both ends of the processing box 1 outside the inlet 103 and the outlet 104;

[0030] Two symmetrical tubular heating jackets 3 are arranged inside the processing box 1, and spiral electric heating tubes 302 are fixed on the inner walls of the heating jackets 3;

[0031] The processing box 1 is the main place for heat shrinkage of the cable sheath. The cable core is covered with an un-heat-shrunk cable sheath. The cable sheath passes through the dust-proof heat-insulating curtain 2 at the entrance 103, enters from the entrance 103, and enters the processing box 1. After passing through the heating sheath 3 and the electric heating tube 302 on the inner wall, the cable sheath is heated and heat-shrunk, and is attached to the outside of the cable core, thereby completing the heat shrinkage. Finally, the cable sheath is led out from the exit 104 through the dust-proof heat-insulating curtain 2;

[0032] The inner walls of the inlet 103 and the outlet 104 are both embedded with rolling balls 102 distributed in a ring array; the arrangement of the balls 102 facilitates the cable sheath to contact the balls 102 when passing through the inlet 103 and the outlet 104, making the rolling friction smoother and facilitating movement.

[0033] The dustproof and heat-insulating curtain 2 comprises a horizontal bar 201 fixed to the end of the processing box 1, and the bottom end of the horizontal bar 201 is fixed with equally distributed curtains 202, and the bottom end of the curtains 202 is lower than the positions of the inlet 103 and the outlet 104;

[0034] The horizontal bar 201 is fixed to the end of the processing box 1 , and a curtain 202 is installed below the horizontal bar 201 . The curtain 202 will block the inlet 103 and the outlet 104 to reduce the heat loss in the processing box 1 .

[0035] Two sets of symmetrically distributed connecting rods 301 are fixed to the outer periphery of the two heating sleeves 3 , and one end of the connecting rod 301 away from the heating sleeve 3 is fixedly connected to the inner wall of the processing box 1 ; the heating sleeve 3 is fixed in the processing box 1 through the connecting rod 301 .

[0036] The two heating jackets 3 are respectively close to the outlet 104 and the inlet 103 , and the inner diameters of the heating jackets 3 and the electric heating tube 302 are larger than the inner diameters of the inlet 103 and the outlet 104 ; thus, the passage of the cable jacket is not affected.

[0037] A controller 101 is fixed on the outer wall of the processing box 1, and the electric control end of the controller 101 is electrically connected to the electric input end of the electric heating tube 302;

[0038] The controller 101 is used to control the operation of the electric heating tube 302 . The controller 101 is a conventional controller 101 , and the specific model is not limited.

[0039] The cable core and the cable sheath pass through the inlet 103, the two heating sheaths 3 and the outlet 104 in sequence and then are led out, and the outer wall of the cable sheath contacts the lowest ball 102; the ball 102 assists the movement of the cable sheath, making it more labor-saving.

[0040] The specific working principle of the utility model is as follows: first, the processing box 1 is placed stably, and the controller 101 is used to control the electric heating tube 302 to make it work, and then a non-heat-shrunk cable sheath is arranged on the cable core, and the cable sheath passes through the dust-proof and heat-insulating curtain 2 at the entrance 103, and enters from the entrance 103. After entering the processing box 1, it passes through the heating sheath 3 and the electric heating tube 302 on the inner wall thereof. Because the electric heating tube 302 generates heat during operation, the cable sheath is heated and heat-shrunk, and sticks to the outside of the cable core, thereby completing the heat shrinkage. Finally, the finished cable is led out from the exit 104 through the dust-proof and heat-insulating curtain 2. When the cable sheath passes through the entrance 103 and the exit 104, it will contact the ball 102, realizing the rolling friction type of travel processing.

[0041] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
