Description

Technical Field

[0001] The utility model relates to the technical field of preparation of electric wires and cables, in particular to a blowing device for producing electric wires and cables. Background Art

[0002] With the development of wire and cable production technology, the production speed of cables is getting faster and faster, but the drying and uniformity of the cable surface has become a bottleneck. The production of wires and cables is that the copper wire is coated with a layer of insulation through an extruder, then cooled in a water tank, and then dried evenly by a blowing device before being rolled. The degree of drying of the cable surface affects the smoothness of the cable appearance. Therefore, in the preparation process of wires and cables, it is necessary to use a blowing device to drive the gas to the cable wire for cooling treatment.

[0003] In the process of cable and wire preparation, in order to maintain the cable preparation efficiency, the cable needs to be kept in a state of rapid transportation continuously. Therefore, when the outside of the cable is blown, the outside of the fast-moving cable needs to be blown. However, in the blowing device, the blowing device will drive the gas from the upper end to the lower end, which will cause the gas to contact the upper part of the cable first, resulting in different blowing efficiencies at the upper and lower ends of the cable, thus affecting the cooling effect of the cable surface. For this reason, we proposed a blowing device for wire and cable production. Utility Model Content

[0004] In view of the shortcomings of the existing blowing devices for the production of wires and cables, the utility model provides a blowing device for the production of wires and cables, which has a blowing sleeve that is sleeved on the outside of the cable, and an inner sleeve is installed inside the blowing sleeve. The inner sleeve drives the gas to flow, and when the gas is transmitted to the inside of the blowing sleeve, the fan blades are pushed to rotate, thereby improving the gas flowability inside the blowing sleeve. At the same time, the gas is evenly driven to be transmitted to the outside of the cable through the air outlet, thereby improving the advantage of more uniform blowing effect on the cable surface, thereby solving the problems raised in the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a blowing device for the production of wires and cables, comprising a support plate, a protective sleeve is fixedly connected to the upper end of the support plate, a bracket is fixedly connected to the side of the protective sleeve, a gas transmission sleeve is installed on the top of the bracket, fans are installed inside the two sides of the gas transmission sleeve, rollers are installed at both ends of the upper part of the support plate, cables are placed on the upper part of the rollers, a gas transmission pipe is fixedly connected to the middle of the lower end of the gas transmission sleeve, a blowing sleeve is fixedly connected to the lower end of the gas transmission pipe, an inner sleeve is fixedly connected to the inside of the blowing sleeve, a cylinder is movably sleeved inside the inner sleeve, a fan blade is fixedly connected to the outside of the cylinder, an air outlet is opened on the inner side of the blowing sleeve, and an auxiliary blowing pipe is installed on the outside of the blowing sleeve.

[0006] Preferably, the protective sleeve is sleeved on the outside of the two sets of blowing sleeves, and the roller is arranged on the side of the protective sleeve.

[0007] Preferably, the fans are arranged in a horizontal direction, and the gas transmission pipe is arranged in the middle of the lower end of the gas transmission sleeve.

[0008] Preferably, the two groups of blowing sleeves are both sleeved on the outside of the cable, and air outlet holes are evenly opened on the inner side of the blowing sleeves.

[0009] Preferably, the fan blades are fitted onto one end of the interior of the blowing sleeve, and the fan blades are arranged at equal intervals outside the cylinder.

[0010] Preferably, one end of the inner sleeve is provided with an opening, and the opening faces the outside of the blowing sleeve.

[0011] Preferably, the auxiliary blowing pipe is installed on the outside of two groups of blowing sleeves, three groups of the auxiliary blowing pipe are installed, and the inner side of the auxiliary blowing pipe is arranged on the outside of the cable.

[0012] Compared with the existing blowing device for wire and cable production, the utility model has the following beneficial effects:

[0013] 1. The blowing device for wire and cable production is connected to the outside of the cable through a blowing sleeve. At the same time, the inner sleeve drives the gas transported to the inside of the blowing sleeve to provide activity space when blowing to the outside of the cable. At the same time, the gas drives the fan blades to rotate. The fan blades increase the circulation time of the gas inside the blowing sleeve. At the same time, the air outlet drives the gas to be blown to the outside of the cable, ensuring the uniformity and synchronization of the gas blowing.

[0014] 2. The blowing device for wire and cable production is installed on the outside of two groups of blowing sleeves through an auxiliary blowing pipe. At the same time, the blowing sleeve drives excess gas to the inside of the auxiliary blowing pipe, and then the auxiliary blowing pipe drives the gas to the outside of the cable installed between the two groups of blowing sleeves. When the outside of the cable is blown, the sufficiency of the gas blowing is improved. BRIEF DESCRIPTION OF THE DRAWINGS
