Problems solved by technology
[0002] In the previous lifting head device, the centering adjustment was carried out by visual inspection, which was difficult to adjust and the adjustment accuracy was not high; the flexible shaft in the reel box was operated by the groove track set by the wire reel, and the concave groove would be broken during operation. Wear occurs, the gap of the concave groove will change, and the running track of the flexible shaft will also change, so the flexible shaft will deviate from the center; if the flexible shaft does not run in the center, the damping sleeve will be worn, and the damping sleeve will be lost; the loss of the damping sleeve It will happen that the flexible shaft cannot run smoothly during the operation, and there will be a swing phenomenon; the swing phenomenon of the flexible shaft will affect the normal production of the crystal

Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0013] Such as figure 1 with figure 2 As shown, a new type of pulling head device according to the present invention includes a reel box 1, an opening 2 is provided on one side of the upper part of the reel box 1, and the reel box at the opening 2 is A scale cover 3 is provided on the body 1, a load-bearing bracket 4 is provided at the connection between the reel box body 1 and the scale cover 3, and a rear cover 5 of the reel box is provided at one side end of the reel box body. A plug 6 is provided at the side end of the cover 5 behind the reel box, a main shaft 7 is provided in the reel box 1, and a winding wheel 8 is arranged on the main shaft 7. 8. A threaded sleeve 9 is provided on the main shaft 7 at one end, and a copper nut 10 is provided on the threaded sleeve 9. The copper nut 10 is connected with the inner wall of the reel box 1 through a...

The invention relates to a novel lifting head device, which comprises a roll box. The roll box at the opening part is provided with a weighing cover. A bearing support is arranged at the joint of the roll box and the weighing cover. A main shaft is disposed inside the roll box. The main shaft is provided with a wire curl wheel. An end of the main shaft, close to a rear seal cap of the roll box, is provided with a first bearing. A pulley bracket is arranged on the bearing support. The pulley bracket is provided with a pulley which is connected to the pulley bracket through a bearing shaft and a second bearing arranged on the bearing shaft. The wire curl wheel is provided with a steel wire rope, which passes through the pulley to freely hang down. A spherical pad is arranged at the joint of the pulley bracket and the bearing support. Steel wire pinch rollers are arranged on the steel wire rope on the pulley. By arranging a fixed vertical point, centering debugging is not required. Manual centering cost is saved; a flexible shaft is prevented from winding and springback; abrasion to a damper bushing is reduced; and the overall operation is stable and reliable.
Description
technical field [0001] The invention relates to a pulling head device, in particular to a flexible shaft pulling head device. Background technique [0002] In the previous pulling head device, the centering adjustment was carried out by visual inspection, which was difficult to adjust and the adjustment accuracy was not high; the flexible shaft in the reel box was operated by the groove track set by the wire reel, and the concave groove would be broken during operation. Wear occurs, the gap of the concave groove will change, and the running track of the flexible shaft will also change, so the flexible shaft will deviate from the center; if the flexible shaft does not run in the center, the damping sleeve will be worn, and the damping sleeve will be lost; the loss of the damping sleeve It will appear that the flexible shaft cannot run smoothly during operation, and there will be a swing phenomenon; the swing phenomenon of the flexible shaft will affect the normal production o...
