Technical Field

The invention relates to an air suction type print wheel, and belongs to the field of cable production equipment.

Background

The identification mark of the wire and cable sheath generally adopts the modes of spray printing and coining, and from the aspect of effect, the spray printing is more economical and convenient, and the coining is more durable. The impressing and printing are that in the process of sheathing a cable, a concave wheel is placed in front of a first water-saving groove, the temperature of a sheathing material which is just extruded is high, the sheathing material is soft, the concave wheel is pressed on the cable which is just extruded with the sheathing material, and the concave wheel rotates around the center along with the sheathing by utilizing the friction force with the sheathing to generate convex printing. The characters printed on the concave character wheel are sequentially arranged according to the circumference of the wheel surface, the center of the concave character wheel is provided with a bearing, the wheel width is slightly larger than that of the cable, and the sheath is easy to deform through extrusion printing to influence the roundness of the cable. If the width of the concave wheel is smaller than that of the cable, two indentations are generated on the surface of the sheath on two sides of the concave wheel.

The mainstream cable formers in the market all adopt crawler-type disc stranders, and the cable cores are pulled to advance by friction force generated by the pressure of a crawler on the cable cores. The advantages are that: the production speed is high; the disadvantages are as follows: the cable core is flat after cabling; the filling specification mismatch leads to multiple factors such as the sinle silk is not round, makes concave character wheel part unable and restrictive coating contact, leads to printing on the cable incomplete.

Detailed Description

As shown in fig. 1 to 4, the air suction type print wheel comprises a wheel body, the wheel surface of the wheel body is provided with a printing strip clamping groove 11, and the printing strips 1 are installed in the printing strip clamping groove 11, namely, the printing strips 1 are installed on the wheel surface of the wheel body in a surrounding mode through the printing strip clamping groove 11. The printing strip 1 is provided with a plurality of hollowed-out printing units, and the hollowed-out parts form fonts, so that different hollowed-out parts can be arranged according to different fonts. As shown in fig. 4, the font part is a hollow part.

The printing strip 1 is fixed on the wheel body through a positioning pin. Or the head end of the printing strip 1 is provided with a first fixing block, the tail end of the printing strip 1 is provided with a second fixing block, the wheel body is provided with a fixing groove matched with the first fixing block and the second fixing block, and the first fixing block and the second fixing block are fixed in the fixing groove through positioning pins. Or, on both sides of the printing strip 1, the head end of the printing strip 1 is provided with a first connecting sheet 5, the tail end of the printing strip 1 is provided with a second connecting sheet 6, and the first connecting sheet 5 and the second connecting sheet 6 are fixed on the side surface of the wheel body through screws.

Under the lettering strip 1, the wheel surface of the wheel body is uniformly provided with a plurality of grooves 2, and the grooves 2 are arranged corresponding to the lettering units.

Be provided with air duct 3 on the wheel body, 3 air outlets 31 one end of air duct is connected with recess 2, and 3 other ends of air duct stretch to the wheel body axle center, and 3 air intakes 32 of air duct are located axle center department promptly, a plurality of air intakes 32 evenly distributed of axle center department.

The bearing 7 is installed at the wheel body axle center, and the wheel body rotates along bearing 7. Specifically, at the axial center of the wheel body, along the axial direction of the wheel body, the bearing 7 is located on one side of the axial center of the wheel body, and the interface between the air duct 3 and the exhaust pipe 8, that is, the air inlet 32, is located on the other side of the axial center of the wheel body.

An exhaust pipe 8 is arranged at the axle center of the wheel body, the exhaust pipe 8 can be used as a support, and the bearing 7 is arranged on the exhaust pipe 8 (steel). After the exhaust pipe 8 passes through the bearing 7, the tail end is reduced in diameter to form an exhaust opening 81. The air inlet 81 is connected to the air inlet 32 of the air duct 3. Exhaust column 8 is connected with the air exhauster, and air exhauster, exhaust column 8, ventiduct 3 and recess 2 form complete negative pressure suction channel, recess 2 this moment be the recess 2 that cable sheath and wheel body contact correspond.
