Description

Guide roller for film coating transmission

Technical Field

The invention relates to the technical field of transmission equipment, in particular to a guide roller for film-coating transmission.

Background

At present, agricultural plastic film mulching has obvious effects of improving ground temperature, maintaining soil humidity, reducing weeds, preventing plant diseases and insect pests and the like, and is an advanced agricultural technology which is fully recognized by vast farmers. At present, the crops generally using the mulching film covering technology mainly comprise cotton, peanuts and the like. However, the implementation of the technology has the problems of more labor, high labor intensity, complex process, incapability of ensuring the seeding covering quality and the like. The existing land preparation machinery, seeding machinery and film covering machinery are provided with shaped products, and guarantee is provided for improving production efficiency. However, the existing film laminating machine has defects, for example, the existing film laminating machine is easy to deviate when a film is laid, so that the film laminating effect is poor, particularly, the automatic film laminating machine is usually discovered only when the film laminating of a whole ridge is finished under the condition of no constant supervision, and the rework cost is high.

The laminating roller structure of the existing laminating machine can only carry out transmission and cannot carry out deviation correction, and in the prior art, the deviation is prevented by arranging limiting mechanisms at two ends of a transmission roller, for example, the laminating roller structure of the laminating machine with the Chinese patent publication No. CN206851554U, but the limiting mechanisms can only limit the deviation without exceeding the range and cannot correct the deviation, and when contacting the limiting mechanisms during deviation of a laminating film, the laminating roller structure can be extruded and folded on one side under the condition of continuing deviation, so that dents are caused, and the dents on the surface of the laminating film can not be corrected and also can be caused. To this end, we propose a guide roller for the transfer of the coating.

Disclosure of Invention

The present invention is directed to a guide roller for film coating transportation, which solves the above problems in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a can correct deflector roll of tectorial membrane transmission of off tracking, includes the mount, be provided with the transmission roller between the mount and correct the roller, the transmission roller is provided with the multiunit, just it is located in the middle of the multiunit transmission roller to correct the roller, the one end of correcting the roller is connected with the detection mobile device.

Preferably, detect the mobile device including installing the motor on the mount, be connected with the lead screw on the output shaft of motor, the lead screw passes through the bearing and is fixed in on the mount of installation motor, just threaded connection has the thread bush on the lead screw, just one side of thread bush is connected with the one end of correcting the roller, be provided with distance sensor on the mount, distance sensor is used for detecting whether the off tracking is gone up to the tectorial membrane commentaries on classics conveying roller to remove through the removal part drive that detects in the mobile device, thereby correct.

Preferably, the fixing frame is connected with a telescopic rod, the output end of the telescopic rod is fixed with a mounting block for mounting the distance sensor, and the telescopic rod can adjust different distances, so that the film laminating machine can be suitable for laminating films with different widths.

Preferably, the telescopic link is electric telescopic handle, and electric telescopic handle is convenient for adjust more, and the regulation distance is more accurate.

Preferably, the outer surface of the correction roller is connected with a guide layer, and a certain friction force is formed between the guide layer and the film covering, so that the effect of driving the film covering when the correction roller moves towards two sides is better.

Compared with the prior art, the invention has the beneficial effects that:

the invention detects two side edges of the covering film through the distance sensors in the detection moving device so as to judge whether the deviation exists, the motor drives the screw rod to rotate after the deviation is detected, the screw rod enables the threaded sleeve to move so as to move the correcting roller, and the distance sensor on which side detects the deviation enables the correcting roller to move towards the opposite side, so that the aim of correcting is achieved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a guide roller for conveying a film comprises a fixing frame 1, wherein a conveying roller 2 and a correcting roller 3 are arranged between the fixing frame 1, the conveying roller is provided with a plurality of groups, the correcting roller 3 is positioned in the middle of the groups of conveying rollers 2, the correcting roller 3 is used for correcting the off tracking of the film and is arranged in the middle of the conveying rollers 2 so as to be conveyed at a normal position after correction, one end of the correcting roller 3 is connected with a detection moving device 4, the film off tracking condition is detected by the movement detecting device 4 and correspondingly adjusted so as to ensure the normal path track to convey, a lifting device (not shown in the figure) is further arranged at the bottom of the detection moving device, the height position of the correcting roller 3 is changed through the lifting device so as not to generate the film when the film is not corrected, and the film is descended through the lifting device after the film is corrected, and then the correcting roller 3 is reset through the movement detecting device, to facilitate the next correction.
