Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1-3, a wire coil dismounting system of a wire twisting machine comprises a lifting mechanism 4 and an operating switch 5.

The stranding machine generally comprises a machine frame 1, a stranding bow 2 and a take-up frame 3, wherein a working cavity 11 is formed in the machine frame 1, an openable door is usually arranged on the front side of the working cavity 11, and the stranding bow 2 and the take-up frame 3 are arranged in the working cavity 11 of the machine frame 1 to ensure the safety during working. The two ends of the twisting bow 2 are rotatably arranged on the frame 1, the take-up stand 3 is arranged on the inner side of the twisting bow 2, and the take-up stand 3 is provided with a detachable take-up reel 31.

The lifting mechanism 4 is arranged in the working cavity 11 and located below the take-up stand 3, and the operating switch 5 is connected with the lifting mechanism 4 and used for operating and controlling the lifting action of the lifting mechanism 4.

The lifting mechanism 4 comprises a lifting platform 41, screw rods 42, guide rails 43, a servo motor 44 and a transmission assembly 45, wherein the screw rods 42 and the guide rails 43 are respectively provided with two groups and are arranged on two sides of the rack 1, two ends of the lifting platform 41 are in up-and-down sliding fit with the guide rails 43 and in threaded fit with the screw rods 42, the servo motor 44 is in transmission fit with the screw rods 42 through the transmission assembly 45, the transmission assembly 45 comprises a transmission shaft, an intermediate shaft and a bevel gear set, the servo motor 44 is in linkage fit with a transmission shaft support through belt transmission, the transmission shaft and the intermediate shaft can also be in linkage fit through belt transmission, and the intermediate shaft and the screw rods 42 are in linkage fit through. The servo motor 44 is started to drive the two sets of screws 42 to move simultaneously, so as to drive the lifting platform 41 to slide up and down along the guide rail 43, thereby realizing the lifting action.

The lifting platform 41 comprises a horizontal supporting surface 411, a tilted surface 412 which is tilted downwards is formed at the front side of the horizontal supporting surface 411, and the take-up reel can be conveniently pushed onto/off the lifting platform 41 through the tilted surface 412.

Of course, the structure of the lifting mechanism 4 may also adopt a lifting device structure as disclosed in chinese patent application No. (CN 109686506A), in addition to the above-mentioned manner.

When the take-up reel 31 needs to be dismounted, the lifting mechanism 4 is started through the operating switch 5, the lifting platform 41 is lifted to a certain height to support the take-up reel 31, after the take-up reel 31 is dismounted from the take-up stand 3, the lifting mechanism 4 is started through the operating switch 5, the lifting platform 41 is lowered to the bottom, and the take-up reel 31 is moved out of the lifting platform 41; similarly, when the take-up reel needs to be installed, the take-up reel 31 is placed on the lifting platform 41, then the lifting mechanism 4 is started through the operating switch 5, so that the lifting platform 41 ascends to a certain height to facilitate installation of the take-up reel, and after the take-up reel is installed, the lifting mechanism 4 is started through the operating switch 5, so that the lifting platform 41 descends to the bottom.

The wire coil can be installed more easily and conveniently through the lifting mechanism 4.

Further, operating switch 5 installs on the inside lateral wall of working chamber 11, and only when stranding machine stop work, after opening the door of working chamber 11 front side, operating personnel just can realize the action to operating switch 5, avoids in stranding machine working process, appears operating switch 5's maloperation.

In addition, still include response subassembly 6, response subassembly 6 is used for the position state of response hank bow 2 and whether control operating switch 5 is electrified, thereby can make operating switch 5 not electrified when hank bow 2 is less than take-up stand 3 thereby ensure that elevating system can not started when hank bow is less than the take-up stand, avoids leading to elevating system and the problem that the pressurized of hank bow damaged that leads to the fact because of the maloperation in the in-process that rises with hank bow contact, improves the security of product use.

The sensing assembly 6 is an ultrasonic sensor capable of sensing distance, and the ultrasonic sensor is mounted on the side wall inside the working cavity 11 and located on one side of the rotary connection position of the winch bow 2 and the rack 1. As shown in fig. 2, when the winch bow 2 is in the horizontal position, the ultrasonic sensor can sense the reflected signal, so as to obtain the signal that the winch bow 2 is in the safe position, and then the ultrasonic sensor can send a signal to electrify the operation switch 5 for use, as shown in fig. 3, when the winch bow 2 is in the non-horizontal position, the ultrasonic sensor cannot sense the reflected signal, so as to obtain the signal that the winch bow 2 is in the safe position, and then the ultrasonic sensor can send a signal to electrify the operation switch 5 for use, so as to ensure the safety of the winch bow 2.

Furthermore, the ultrasonic sensor is positioned at the inner side of the joint of the opposite twisting bows 2, so that the error induction of the ultrasonic sensor caused by the fact that a worker enters the working cavity is avoided.

Besides, the winch bow position sensing assembly 6 can also adopt a hall sensor to acquire the rotation angle of the winch bow 2, and only when the winch bow 2 is in a safe position, the hall sensor sends a signal to enable the operation switch 73 to be powered and used, otherwise, the hall sensor sends a signal to enable the operation switch 73 to be not powered and not used.

Of course, there are many ways to implement the function of the winch bow position sensing assembly 6, such as a contact switch, and the like, which are not described herein in detail.
