Belt dragger

Abstract

The invention provides a belt dragger which comprises a stand (1), a first drive device, a dragging wheel (6), a second gear (7) and a counter torque device, wherein an outer belt (3) is arranged on the stand (1), the first drive device is arranged on the stand (1), the output end of the first drive device is provided with a first gear (8), the dragging wheel (6) is arranged on the stand (1), an inner belt (11) matched with the outer belt (3) is arranged on the dragging wheel, the second gear (7) is matched with the first gear (8) and connected with the dragging wheel (6) and used for drivingthe dragging wheel to rotate; and the counter torque device is arranged on the stand (1) and comprises a second drive device and a counter torque gear (103) arranged at the output end of the second drive device and meshed with the second gear, and a torque applied to the second gear (7) is opposite to the torque applied to the second gear (7) by the first gear (8) in a direction. The belt draggerrealizes that a cable core is more stably dragged, and further ensures that the operation speed of the cable core is more uniform, thus bamboo joints during extruding materials are avoided.

Description

technical field [0001] The invention relates to the technical field of strapping tractors, and more specifically, relates to a strapping tractor with an anti-torque device. Background technique [0002] Taping tractor is a very important equipment in the cable process. After the wire core (such as aluminum core and copper core) enters the tape tractor, it moves forward under the traction of the tape tractor. The wire core coming out of the tube passes through the extruder to extrude the material (plastic, rubber, etc.) on the wire core. [0003] In the process of extruding the material of the wire core, the running speed of the wire core is very important, which directly affects the quality of the extruded plastic of the wire core. [0004] Please refer to the attached figure 1 , which shows a schematic structural view of an existing tape tractor. The tape tractor includes: a motor 04, a gearbox and a reducer 05, a second gear 07, a traction wheel 06, a first gear 08, an ...

AI Technical Summary

Problems solved by technology

[0005] However, in the existing tape tractor, the backlash of the second gear 07 and the first gear 08 is large, which causes the motor and the traction wheel to respond inconsistently during the gear transmission process, and the traction wheel does not run smoothly, resulting in unstable tension of the wire core. Stability, which eventually leads to unstable running of the wire core, and its running speed varies from time to time. In the process of extruding the wire core, the material extruded by the extruder wraps the wire core, because the extruded material is uniform. , so when the running speed of the wire core is slow, the extruded material will lead to a large diameter of the cable after wrapping the material. small diameter

The diameter of the above-mentioned cables after extruded materials fluctuates greatly, that is, bamboo knots occur (that is, the entire cable is similar to bamboo knots), which affects the quality of the cables
