Description

Technical Field

[0001] The present invention relates to the technical field of cable installation for tobacco equipment, and in particular to the technology of installing and fixing cables used in a rolling and packaging equipment under a three-way or multi-way cable tray structure, and specifically to a cable tray with a roller-type anti-wear adjustable function. Background Art

[0002] The tobacco industry's various equipment, like other general equipment, also requires the centralized laying, installation and fixing of cables, signal lines, air pipelines or other pipelines between the equipment and the electrical cabinet, the main equipment and the sub-equipment. The tobacco packaging equipment is particularly special, so here we conduct technical research and development on some common problems in the cable laying process of packaging equipment.

[0003] At present, the mainstream equipment for tobacco wrapping is the ZB45 packaging unit, which is mainly composed of several independent equipment such as small box packaging machine, box outer transparent paper packaging machine, strip box packaging machine, strip outer transparent paper packaging machine and electrical cabinet ancillary facilities. The power supply between equipment and between equipment and electrical cabinets is connected by cable lines. These lines are laid and installed in the main bridge system, and then enter the connection position of each equipment from the main bridge system. The main bridge is generally a two-way straight-through bridge structure. The operation method is to put the cable into the bridge base first, and then cover the bridge cover to complete the cable laying work. Finally, when the cable and various pipelines are connected to each split equipment, due to the different connection points, the cable will have multiple directions, so it will Three-way or multi-way bridges are used for laying. The laying method of this bridge is different from that of the straight-through bridge. The bridge cover is covered first, and then the cables and other pipelines are passed through each outlet of the bridge cover one by one. Because the laying space is small, the number of cables is large, the cables are thick and hard, and the cable bending curvature is small (about 130-145 degrees), it is not easy to bend and turn. In addition, during the laying process, since the outlets of the bridge are generally fixed and cannot be adjusted, the operation is very difficult and the work efficiency is low. In addition, during the laying process, the cable sheath is easy to produce long-term friction with the contact surface of the metal bridge, which will cause the cable sheath to be damaged to varying degrees, causing the outermost protective layer of the cable to be worn and affect the cable quality. Therefore, the current situation is that the cables and other pipelines in the final access equipment do not use bridges, but are directly exposed, resulting in disorder and chaos on the site, and there are certain safety hazards. At present, there are more than 800 sets of ZB45 packaging units in the national tobacco industry, all of which have the above situation. This situation not only affects the overall appearance of the equipment, but also poses certain safety hazards due to the exposed cables, and does not meet the requirements of lean management and on-site management in the tobacco industry.

[0004] The present invention is based on the above-mentioned common problems. On the basis of the existing known technology and current status of cable bridges, in order to overcome and solve the problems of difficult operation, damage to cables and messy on-site, the applicant has conducted multiple sufficient investigations, analyses and redesigns on-site, and provided key technologies for roller-type wear-resistant adjustable cable bridges. By setting a push-pull guide outlet and a guide roller structure, the size of the guide outlet can be adjusted according to needs. With the cooperation of dual technologies, the operability of three-way or multi-way cable bridge connections and cable outlets can be flexibly responded to; the guide roller replaces the original sliding friction with rolling friction, which solves the possibility of wear of the cable sheath by the metal surface of the bridge during the laying of the cable, and perfectly solves the many problems of exposed cables and many safety hazards in the "last meter" of cable laying work of the ZB45 model packaging unit in the current tobacco industry, achieving the effect of easier operation, higher efficiency, lean management and higher level of on-site management than conventional cable bridge structures. At the same time, this technology can also be promoted and applied to similar professional technologies in other industries. Summary of the invention

DETAILED DESCRIPTION

[0029] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-5As shown, a roller-type wear-resistant adjustable cable tray includes a tray base 1, a tray cover 2, a guide roller 3, a guide outlet 4 and a lock 5. It is characterized in that: the tray base 1 is a U-shaped channel steel structure, which is composed of a left tray base 11, a first bolt 12, a U-shaped connecting frame 13, a first long through hole 14, a right tray base 15, a lock 5 and a movable plate 16 from left to right; the left tray base 11 and the right tray base 15 are fixedly connected to the two ends of the U-shaped connecting frame 13 respectively; the upper end of the U-shaped opening of the right tray base 15 is provided with a guide roller 3, and the upper right of the guide roller 3 is provided with a guide outlet 4, and the guide roller 3 is provided with a guide outlet 4. The outlet 4 is composed of a front U-shaped frame 45 and a rear U-shaped frame 41, and is installed on the front and rear ends of the bridge cover 2 in a front-to-back order; the bridge cover 2 is composed of a right cover 25, a first connecting plate 24, a second long through hole 23, a second bolt 22 and a left cover 21 from right to left; the right cover 25 and the left cover 21 are fixedly connected to the two ends of the first connecting plate 24 to form a bridge cover 2; the bridge cover 2 is locked with the bridge base 1 by a lock 5.

[0031] The present invention is implemented in this way: a roller-type wear-resistant and adjustable cable bridge. When the cable laying work enters the final stage, the length suitable for the cable bridge installation is adjusted and fixed by adjusting the length dimensions between the bridge base, the bridge cover and the retractable U-shaped connecting frame according to the specific conditions of the installation space and reserved position of the on-site bridge. Then, according to the number of cables in the straight-through cable bridge or the direction of the straight-through cable outlet, the size or outlet position of the straight-through bridge outlet is adjusted by pushing and pulling the movable plate. Then, the cables and other lines that need to be directly connected to the equipment sent by the main bridge system are neatly laid in the bridge base, and the cables that need to be laid from the guide outlet are first passed through the guide outlet and the bridge cover is covered; then, the retractable connection structure set for the bridge guide outlet can be used to make The opening area of ​​the guide outlet is increased by more than 30% to 50%, and then the cables and other pipelines are laid one by one along the guide roller and from the guide outlet. Under the rolling action of the guide roller, the direct friction between the cable sheath and the contact surface of the metal bridge is avoided, the cable is protected from damage during the laying process, and the construction difficulty is reduced. When all the cables are laid in place, the telescopic connection structure of the guide outlet is adjusted to restore the guide outlet to its original state or other position suitable for the placement of the cable and fix it, which further reduces the rebound of the cable after bending. At this point, after the laying of the cable bridge, bridge cover and cable fully meets the requirements, the four locks can be fastened, thus completing the installation and fixation of the entire cable line, thereby efficiently realizing the three-way or multi-way cable laying and installation work.
