Embodiment Construction

[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0017] Such as figure 1 As shown, the present invention provides a roller blind winding device, which includes a threaded shaft 2, a traveling sleeve and a support for a pulley block, the traveling sleeve is rotatably sleeved on the threaded shaft 2, and the traveling sleeve The thread matched with the threaded shaft 2 can move along the length direction of the threaded shaft 2 with the rotation of the threaded shaft 2, and the support of the unloading pulley block is fixedly arranged on the outer surface of the walking sleeve. In this way, when winding, the threaded shaft 2 rotates clockwise, and the wire harness passes through the unloading pulley bracket. After unloading the unloading pulley bracket, the wire is ...

Abstract

The invention relates to the field of a greenhouse and especially relates to a shutter winding device. The shutter winding device comprises a threaded spindle, a walking sleeve and a force-unloading pulley block bracket, wherein the walking sleeve is rotatably sleeved on the threaded spindle; the walking sleeve is matched with a thread of the threaded spindle and is capable of moving along the length direction of the threaded spindle following the rotation of the threaded spindle; the force-unloading pulley block bracket is fixedly arranged on the outer surface of the walking sleeve. When the threaded spindle clockwise rotates, a wire harness is penetrated through the force-unloading pulley block bracket; after the force is unloaded by the force-unloading pulley block bracket, the wire is wound on the threaded spindle; due to a constraining force of the wire harness, the stress endured by the force-unloading pulley block bracket on a winding position is balanced and the force-unloading pulley block bracket cannot be rotated following the threaded spindle; the force-unloading pulley block bracket is fixedly arranged on the outer surface of the walking sleeve and the walking sleeve is rotatably sleeved on the threaded spindle, so that the walking sleeve can realize displacement in the manner of matching with the thread of the threaded spindle.

Description

technical field [0001] The invention relates to the field of greenhouses, in particular to a roller blind winding device. Background technique [0002] At present, when the shutter machine is working, it is operated by one person. Because the quilt is curled or pulled obliquely when laying, it will cause uneven or reverse winding. If it is not found in time, it will cause the destruction of the skeleton. Maintenance is time-consuming and afraid of fire, and time-consuming and labor-intensive. Injuries happen from time to time. Therefore, it is very time-consuming to adjust the rope from time to time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a winding device for roller blinds, which solves the problems of uneven winding and dangers easily caused by workers when straightening. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a windin...
