Simultaneously because of the winding of plastic film on the tooth mounting bracket, can cause the hookup position of cross mounting bracket and tooth mounting bracket to twine the plastic film easily, lead to the tooth mounting bracket to be stuck nonrotation, the unpowered source stop work of guider, the stability decline of whole machines influences the incomplete membrane and picks up the rate.
Disclosure of Invention
The invention aims to solve the technical problem of providing a film picking mechanism with an externally hung guide wheel aiming at the defects of a guide device of the film picking mechanism in the prior art, and solves the problems that the guide wheel is seriously worn and the plastic film is wound and stuck, so that the guide of film picking teeth of a residual film recycling machine cannot be realized, the whole machine tool is unstable in work and the residual film pickup rate is low, and the machine tool operation efficiency and the machine tool stability are improved.
The technical scheme adopted for solving the technical problems provided by the invention is as follows:
a film picking mechanism with an externally hung guide wheel, which comprises a cross-shaped mounting rack, a film picking shaft, a tooth mounting rack and film picking teeth, the cross-shaped mounting rack is sleeved at two ends of the membrane picking shaft, the membrane picking shaft is arranged on the frame through a bearing seat, a tooth mounting rack is axially connected with the cross mounting rack, a plurality of film picking teeth are arranged on the tooth mounting rack, an anti-winding sleeve is arranged between the tooth mounting rack at one end of the film picking shaft and the cross mounting rack, the other end of the film picking shaft is provided with an externally-hung guide wheel device which comprises a connecting rod, one end of the connecting rod is coupled with one end of the tooth mounting rack, the other end of the connecting rod is mounted on the inner end surface of the outer guide wheel through a connecting rod shaft, the outer end face of the outer guide wheel is provided with a plurality of bearings, the frame is provided with an inner guide wheel, and the inner guide wheel is positioned in a circle formed by the bearings and is in line contact with each bearing.
The inner guide wheel is in contact with the outer guide wheel in the radial direction, the inner guide wheel is only in contact with a bearing arranged on the outer guide wheel in the axial direction, and the outer guide wheel pushes the bearing to roll on the outer circumferential surface of the inner guide wheel under the driving of the connecting rod.
And a plurality of film raising teeth are detachably arranged on the tooth mounting rack.
According to the invention, the anti-winding sleeve is additionally arranged between the cross-shaped mounting frame and the tooth mounting frame, so that the phenomenon that the tooth mounting frame is clamped and does not rotate when a mulching film is wound between the cross-shaped mounting frame and the tooth mounting frame is prevented, the normal rotation work of the inner guide wheel and the outer guide wheel is ensured, and the operation reliability of the machine tool is improved; the surface contact type sliding support of the inner guide wheel and the outer guide wheel and the bearing line contact type rolling support arranged on the outer end surfaces of the inner guide wheel and the outer guide wheel are improved into simple line contact of the inner guide wheel and the bearing, so that the friction and abrasion of the bearing and the inner guide wheel are reduced, the power consumption of the film picking mechanism is reduced, and the operation stability of the machine tool is improved. Simultaneously with the design of the film picking teeth for installing the demountable installation mode on the tooth mounting bracket through the nut, if the film picking teeth appear damages such as bending, the film picking teeth can be replaced quickly to continue the operation, and the operation efficiency of the machine tool is improved.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in the attached drawings 1-3, the membrane selecting mechanism with the externally-hung guide wheel comprises a cross mounting frame 1, a membrane selecting shaft 5, a tooth mounting frame 10 and membrane selecting teeth 11, wherein the cross mounting frame 1 is mounted at two ends of the membrane selecting shaft 5 through flange plates 3, bearing seats 2 are mounted at two ends of the membrane selecting shaft 5 and close to the outside, and the membrane selecting shaft 5 is mounted on a rack 14 through the bearing seats 2. Four tooth mounting brackets 10 equipartition suit are on cross mounting bracket 1, and a plurality of membrane-raising teeth 11 pass through nut 4 equidistance detachable and install on tooth mounting bracket 10. Install antiwind cover 12 between the tooth mounting bracket 10 of choosing the one end of membrane axle 5 and cross mounting bracket 1, antiwind cover 12 is installed and is located cross mounting bracket 1 inboard at tooth mounting bracket 10 both ends. An external guide wheel device is arranged at the other end of the film picking shaft 5 and comprises a connecting rod 9, one end of the connecting rod 9 is connected with one end of a gear mounting frame 10 in a shaft mode, the other end of the connecting rod 9 is mounted on the inner end face of an external guide wheel 8 through a connecting rod shaft 13, a plurality of bearings 6 are mounted on the outer end face of the external guide wheel 8, an internal guide wheel 7 is mounted on a rack 14, a groove is formed in the outer edge of the internal guide wheel 7, the bearings 6 roll on the surface of the internal guide wheel 7, so that the internal guide wheel 7 is not in contact with the external guide wheel 8 in the radial direction, the internal guide wheel 7 is only in contact with the bearings 6 mounted on the external guide wheel 8 in the axial direction, and the external guide wheel 8 drives the bearing 6 to roll on the outer circumferential.
During operation, choose membrane axle 5 to rotate, drive cross mounting bracket 1 and tooth mounting bracket 10 and rotate, choose membrane tooth 11 to follow tooth mounting bracket 10 and rotate and begin work.
