The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the disclosure of the specification, the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships that are based on those shown in the drawings, which are merely for convenience in describing the invention and to simplify the description, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and, therefore, the above-described terms should not be construed as limiting the invention.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

Referring to fig. 1 and 2, a curtain door driving apparatus according to a preferred embodiment of the present invention will be described in detail below, wherein the curtain door driving apparatus 100 includes a driving shaft 10, a driving mechanism 20, a pay-off mechanism 30 and a balancing mechanism 40, wherein the driving shaft 10 extends in a predetermined direction in a manner capable of being driven to rotate. Generally, the extending direction of the driving shaft 10 is parallel to the direction of the plane of the door curtain 50. In addition, the transmission shaft 10 is composed of two half shafts 11 connected in a straight line, and the two half shafts 11 are symmetrically sleeved with a multi-groove guide wheel 12. The driving mechanism 20 includes a driving motor 21 and a transmission seat 22, wherein a speed reducer and two couplers 23 are disposed in the transmission seat 22, the speed reducer is rotatably connected to a driving end of the driving motor 21, the two couplers 23 are disposed on two sides of the speed reducer respectively, and the two half shafts 11 are fixedly connected to the opposite ends of the two couplers respectively. In this way, the two half shafts 11 can be driven to rotate synchronously by a motor, that is, the transmission shaft 10 is driven to rotate, and then the two guide wheels 12 are driven to rotate synchronously. In addition, a rotating motor may be provided at any end of the transmission shaft 10 to control the two guide wheels 12 of the transmission shaft 10 to rotate synchronously, but it takes up a large space and is inconvenient to install, and it is easy to apply additional gravity to the transmission shaft 10 at the installation end to affect the balance of the transmission shaft 10.

In addition, the pay-off mechanism 30 includes two pay-off rollers 31 and two pay-off wires 32 wound on the pay-off rollers 31, wherein the pay-off rollers 31 are distributed corresponding to the guide wheel 12, and one end of each of the pay-off wires 32 on each of the pay-off rollers 31 is fixedly connected to one wheel groove of the guide wheel 12, and the other end of each of the pay-off wires 32 is fixedly connected to the door curtain 50, so that the door curtain 50 can be driven to move up and down directionally through the half shaft 11, the guide wheel 12 and the pay-off wires 32 in sequence when the driving motor 21 operates.

In addition, it is particularly noted that the balancing mechanism 40 includes at least one balancer 41 and a balancing rope 42 disposed at an output end of the balancer 41, wherein the balancer 41 is located at the other side of the transmission shaft 10 opposite to the paying-off drum 31, that is, the paying-off mechanism 30 is located at the left side of the transmission shaft 10, the balancing mechanism 40 is located at the right side of the transmission shaft 10, and the other end of the balancing rope 42 is fixed in the other wheel groove of the guide wheel 12. When the driving motor 21 is operated to drive the guide wheel 12 to rotate directionally through the half shaft 11, the guide wheel 12 drives the wire releasing rope 32 and the balancing rope 42 to release in opposite directions in different wheel grooves, so that the wire releasing rope 32 and the door curtain 50 are effectively balanced through the balancing rope 42.

More specifically, when the door curtain 50 descends, on the basis of the force applied by the self-gravity of the door curtain 50, the driving motor 21 rotates reversely to drive the guide wheel 12 to rotate leftward, the wire releasing rope 32 is gradually released in the wheel groove, at the same time, the balancing rope 42 is gradually wound on the guide wheel 12, and as the descending distance of the door curtain 50 increases, the reaction force applied by the balancing rope 42 to the guide wheel 12 by the balancer 41 is stronger, so as to slow down the descending speed of the door curtain 50, buffer the door curtain 50, and be safer to use; in addition, since the door curtain 50 has a large weight, the driving motor 21 may be shortened due to a certain adverse effect of the falling speed, and the driving motor 21 may be indirectly protected by applying an additional force to limit the falling speed of the door curtain 50 under the action of the balancing mechanism 40.

As a preferred embodiment, the balancer 41 is implemented as a spring balancer or a torsion spring, which is low in cost and easy to manufacture, so that energy can be accumulated based on a buffering action generated when the door curtain 50 descends during transmission, and when the door curtain 50 needs to ascend, the accumulated energy is released in an auxiliary manner in accordance with the forward rotation of the driving motor 21, thereby reducing power consumption of the driving motor 21, prolonging the service life thereof, and saving cost.

Preferably, the guide wheel 12 is implemented as a two-slot guide wheel, and the balancer 41 is implemented as two, wherein two balancers 41 are respectively provided corresponding to the two payoff drums 31, configured to synchronously apply balanced forces on both sides of the top of the door curtain 50. Therefore, more balance force can be applied, the operation of the door curtain 50 is more stable, the cost is further saved, and the stress of the transmission shaft 10 can be balanced.

In addition, with reference to fig. 1 and 3, the present application further provides a damping type can curtain door, which includes a mounting platform 200, the above-mentioned can curtain door transmission device 100, and a door body 300, wherein the can curtain door transmission device 100 is disposed at the left end of the top of the mounting platform 200, and the door body 300 extends in the vertical direction at a side close to the can curtain door transmission device 100, and is symmetrically and fixedly connected with the pay-off lines 32 on the two pay-off drums 31 through the top thereof. In the operation process of the damping type can curtain door, the balancing mechanism 40 in the can curtain door transmission device 100 effectively balances the gravity of the door body 300 and the rotation driving force of the driving motor 21 through the guide wheel 12, so that the door body 300 can be buffered to descend, the damping type can curtain door is safer to use, the operation of the driving motor 21 can be effectively buffered, the power consumption of the driving motor is reduced, the service life of the driving motor 21 is prolonged, and the operation cost is reduced.

Preferably, the canister curtain door actuator 100 and the door body 300 are implemented in two and are correspondingly disposed at opposite ends of the mounting platform 200.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The advantages of the present invention are complete and effective.
