Description

Technical Field

[0001] The invention relates to the technical field of wire or cable processing equipment, and in particular to a device for automatically cutting off weaving or winding inside a wire. Background Art

[0002] At present, there are many kinds of wires for electronic products used in the market. Among them, wires with excellent anti-interference and structural performance usually include a core wire, an inner filling layer, a braided layer or a winding layer, and an outermost protective shell arranged from the inside to the outside. In the actual production process, this type of wire usually needs to strip the braided layer or winding layer at its connection end and the outermost protective shell, and perform inspection or port connection operations after stripping according to actual production needs. At present, there are many stripping devices for the outer protective shell of wires on the market, and the technology can basically meet the requirements of production and process standards. However, the braided layer or winding layer of the wire is relatively thin and the material used is relatively soft. It is difficult for existing processing equipment to completely strip and clean the braided layer or winding layer. It is necessary to manually trim and clean the remaining flying wires for a second time. During the second manual trimming and cleaning, the problem of missing cleaning will occur due to manual errors. The remaining flying wires are prone to short circuits or poor electrical performance. Therefore, a device that can completely strip and remove the braid or winding without manual secondary cleaning is urgently needed in the current market. Summary of the invention

After the upper jaw 202 and the lower jaw 208 reach the specified height, the first cylinder 203 drives the upper jaw 202 to close and clamp the upper half of the inner braided layer or winding, and the second cylinder 209 drives the lower jaw 208 to close and tighten the lower half of the inner braided layer or winding. Then drive the upper support plate 205 to slide upward, and in the process of upward movement, the upper clamp 202 maintains a continuous closed state, that is, the closed mouth of the upper clamp 202 gradually closes completely as the height of the upper support plate 205 rises, until it reaches a completely closed state when leaving the highest point of the wire, and the operating principle of the lower clamp 208 is the same as that of the upper clamp 202, except that the movement direction of the lower support plate 211 is opposite to that of the upper support plate 205. This operation can ensure that the upper clamp 202 and the lower clamp 208 always maintain a clamped inner braided layer or winding state, and completely pull and tear the inner braided layer or winding from the middle of the wire to avoid residual silk threads. After the inner braided layer or winding is straightened, drive the rear cutter 103 to move forward and close with the front cutter 102, cut the straightened inner braided layer or winding, and the upper clamp 202 and the lower clamp 208 are loosened, and the inner braided layer or winding waste falls into the waste discharge hopper 611. Straightening first and then cutting the inner braid or wrapping it can ensure a thorough cut without leaving any residual silk.

[0059] The number of the upper clamping jaws 202 and the number of the lower clamping jaws 208 are both two, and correspondingly, the number of the first cylinders 203 and the number of the second cylinders 209 are both two. The two first cylinders 203 are fixed to the two sides of the upper supporting plate 205, and the two second cylinders 209 are fixed to the two sides of the lower supporting plate 211.
