Description

TECHNICAL FIELD

[0001] The present application relates to the field of cable production, in particular to a cable marking machine. BACKGROUND

[0002] After the cable production is completed, it is usually marked to identify the relevant parameters such as the specifications and production batch of the cable. In the prior art, a portable marking machine is generally used for small cables, which is similar to the principle of a printing machine, and a segment is printed every time a segment is used. This method is only suitable for small cables. For large cables, laser printing is usually performed on the cable sheath before the cable is wrapped with an outer sheath. Then the cable is wrapped. Since the cable sheath has a shrinkage property, it is difficult to ensure that the font is clear and complete. A more common marking device is an intelligent laser marking machine. This device is expensive, and generally needs to be matched with an intelligent production line for operation, which requires high operating personnel and high use and maintenance costs, thereby increasing the production cost. In actual use, some less dense markings such as length coding and cable warning markings also need to be printed, usually one to two meters per print. The printer head of the intelligent marking machine is very dense, and the whole machine needs to be started during use. The operation of the single print head leads to ineffective use of the device and waste of production capacity. SUMMARY

A detachable marker is arranged on one side of the marking support plate facing the cable passage. A gear pair is arranged on the rear support. The gear pair drives the marking mechanism to make the marking support plate reciprocate towards and away from the cable passage. The upper and lower marking support plates are simultaneously introduced into the cable passage from the same side of the cable passage.

[0006] Further, the gear pair comprises an upper gear and a lower gear that are engaged with each other. The upper gear and the lower gear are the same in size and number of teeth. The lower gear is driven to rotate by the driving mechanism.

[0024] like Figure 1 As shown, a cable marking machine includes a body 1, which comprises a cuboid frame structure formed by a base plate 101, a rear support 102, a top plate 103, a front sealing plate 104, a left sealing plate, and a right sealing plate. A drive mechanism 2 is provided outside the body 1, which is generally an electric motor or a hydraulic motor. A cable channel 4 is provided at the center of the body 1. Two sets of marking mechanisms 3 with the same structure are provided inside the body 1, symmetrically arranged vertically along the cable channel 4. The marking mechanism 3 includes a rotary kinematic pair and a marking support plate 305 provided at the moving end of the rotary kinematic pair. A detachable marking device is provided on the side of the marking support plate 305 facing the cable channel 4. A gear pair is provided on the rear support 102.

[0025] In use, the cable 5 passes through the cable passage 4, the driving mechanism 2 drives the marking support plate 305 to move back and forth towards the cable passage 4 through the gear pair, when the marking device contacts the cable 5, the marking device prints the mark on the cable 5. The marking device can adopt a printing plate, or can adopt laser printing. In order to make the working state better, generally, a traction mechanism and a winding mechanism are also needed to be equipped at the inlet and outlet of the device, and a tensioning mechanism can also be set as necessary, which can be referred to the prior art.

Taking the marking mechanism 3 above the cable passage 4 as an example, the rotary motion pair includes four cranks which are hinged at four corners of the marking support plate 305, which are the first crank 301, the second crank 302, the third crank 303 and the fourth crank 304, the other end of the crank is fixedly connected with the crank shaft 310 which is perpendicular to the crank face, the crank shaft 310 of the first crank 301 is fixedly connected with the central shaft of the upper gear 201, when the upper gear 201 rotates, the first crank 301 is driven to move in a circular motion, the crank shaft 310 of the second crank 302 is hinged on the rear support 102; the other end of the third crank 303 and the fourth crank 304 is hinged on the front sealing plate 104 through the crank shaft 310; the four cranks always keep parallel state when moving, and each two adjacent cranks form a parallelogram, when the first crank 301 rotates, the remaining cranks rotate together, thereby driving the marking support plate 305 to rotate in a horizontal state. The movement principle of the marking mechanism 3 below the cable passage 4 is the same, since the movement directions of the upper gear 201 and the lower gear 202 are different, the movement directions of the upper and lower marking support plates 305 are also different, but always keep from the same side into the cable passage 4 synchronously.

[0027] In a preferred embodiment of the present application, the crank shaft 310 of the crank on the same side of the marking support plate 305 is provided with a linkage assembly, which ensures the synchronous movement of the cranks on the same side.

When one of the cranks moves, the cam 309 rotates together, the cam 309 drives the linkage rod, thereby ensuring the synchronous movement of the cranks on the same side of the cable channel 4. In addition, the marking support plate 305 is connected by a connecting shaft penetrating the marking support plate 305, and the connecting shaft is directly hinged at both ends of the crank or fixedly connected at both ends of the crank, and the connecting shaft rotates in the marking support plate 305.

This mode can replace different marking dies 306 according to the size of the cable 5, and the marker can be a laser type or a printing type. When the printing type marker is used, the body 1 is further provided with a drying device 7 at one end. The drying device 7 can be an electric heating drying box, so that the cable 5 passes through the middle, and when the marker is a simple ink printing plate or the like, the marker can be dried. The marker can also be an electric heating needle. The specific structure and principle of the marker can refer to the prior art
