Description

Technical Field

[0001] The present application relates to the technical field of taping machines, and in particular to a telescopic single-arm center frame. Background Art

[0002] The taping machine, also known as the wrapping machine, rotates the insulating tape through a turntable and wraps the insulation around the wire rod to increase the thickness and improve the insulation performance.

[0003] When wrapping tape on an existing tape wrapping machine, the tape wrapping disk continuously rotates to wrap the insulating tape around the wire rod. However, during the winding process, the wire rod to be processed will shake due to the tension of the winding, which affects the tightness of the winding and cannot guarantee the quality. This problem needs to be solved urgently. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a telescopic single-arm center frame.

[0005] The present application provides a telescopic single-arm center frame, comprising a taping machine head; the taping machine head comprises a main board; a clamping assembly for securing a wire rod to be processed is provided on the main board; the clamping assembly comprises a telescopic support arm fixedly mounted on the main board; a fixed caliper is fixedly mounted on the telescopic support arm; a matching dynamic caliper is hingedly connected to the fixed caliper; the dynamic caliper is driven by a driving mechanism; and the driving mechanism is hingedly mounted on the dynamic caliper.

[0006] Furthermore, the taping machine head is provided with a through hole for the wire rod to be processed to pass through and an opening connected to the through hole; the opening is arranged along the radial direction of the through hole.

[0007] Furthermore, the telescopic support arm is a double-rod cylinder; the end of the cylinder rod is fixedly connected to the fixed caliper and moves along the radial direction of the through hole.

[0008] Furthermore, the fixed caliper and the dynamic caliper are respectively provided with limiting grooves, which are assembled into a limiting area after being engaged.

[0009] Furthermore, the limiting groove is a 90° concave notch; and the limiting area is a rectangle.

[0010] Furthermore, a corresponding bracket is provided on the fixed caliper corresponding to the driving mechanism; the driving mechanism is a single-rod cylinder; the single-rod cylinder is fixedly mounted on the bracket, and the piston rod is connected to the dynamic caliper.

[0011] The advantages and positive effects of this application are:

[0012] This technical solution provides a clamping assembly on the taping machine head to limit the position of the wire rod to be processed, thereby preventing the wire rod from shaking excessively due to the tension of the insulating tape.

[0013] When the taping machine head is working, the telescopic support arm extends out to cooperate with the clamping assembly to control the wire rod to be processed to prevent the wire rod to be processed from shaking too much; when encountering a bent angle shape of the wire rod to be processed, the clamping assembly releases the clamping and the telescopic support arm retracts to make space for bending the wire rod to be processed.

[0014] The center frame assembly of the present technical solution is centrally arranged on the left side of the taping machine head end face, and does not occupy the space on the right side of the taping machine head end face, thereby facilitating the taping machine head to adapt to the wire rod to be processed with a bending angle.

[0015] The clamping assembly clamps the wire rod to be processed through a dynamic caliper and a fixed caliper. The opening and closing of the dynamic caliper and the fixed caliper are controlled by a single-rod cylinder. Therefore, the wire rod can be clamped by controlling the extension and contraction of the single-rod cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
