Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of empty bottle filling production line, more particularly to an empty bottle conveying air duct. BACKGROUND

[0002] In order to improve production efficiency, an empty bottle conveying air duct is generally used to convey empty bottles on the filling production line. When working, the empty bottles slide along the bottle neck slide under the drive of the bottle blowing machine. The bottle neck slide has two guide bottle strips arranged in parallel and having a certain spacing on both sides. The bottle neck of the conveyed empty bottle is located between the two guide bottle strips, and the support ring of the empty bottle is supported by the upper surface of the guide bottle strip and can slide thereon.

[0003] However, when the existing empty bottle conveying air duct is used to convey empty bottles, the empty bottles often become skewed and then get stuck at a certain position, hindering the normal conveying of the empty bottles, affecting the subsequent filling process, and even affecting the production process. Currently, a person is usually assigned to monitor and, when the empty bottle gets stuck at a certain position, the person shakes or pulls the empty bottle to make it continue to convey. However, due to the long empty bottle conveying air duct and the continuous production for 24 hours, the conveying speed of the empty bottles is relatively fast, and the worker often cannot timely find the stuck position, which may also affect the production process due to inadequate monitoring, and the labor is relatively large.

[0004] Therefore, it is an urgent problem for those skilled in the art to provide an empty bottle conveying air duct that runs smoothly. SUMMARY

[0005] Therefore, the present application provides an empty bottle conveying air duct that can timely find the stuck position and take measures to ensure the normal and continuous conveying of the empty bottles and the production process.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0007] An empty bottle conveying air duct is installed between a bottle blowing machine and a filling machine, comprising a shell, a lifting assembly, an ultrasonic sensor, and a controller. The shell has a bottle neck slide in the center of the bottom. The lifting assembly is installed on the shell by a linear guide rail driven by a stepping motor. The ultrasonic sensor is installed on the lifting assembly. The ultrasonic sensor is electrically connected to the controller, and the controller is electrically connected to the lifting assembly.

[0008] Through the above technical solutions, the present application has the following advantages:

[0009] The lifting assembly can slide on the shell along the linear guide rail, and the ultrasonic sensor detects the empty bottle, when no empty bottle is detected, the controller drives the lifting assembly to lift the empty bottle stuck in the adjacent position, so that the empty bottle stuck in the adjacent position moves forward, the position of the stuck bottle is found in time, and measures are taken to ensure the continuous conveying of the empty bottle, reduce the labor, and ensure the production process.

[0010] Further, the lifting assembly comprises a support frame, a bracket, two telescopic cylinders and a supporting plate, two linear guide rails are respectively fixed on the two side walls of the shell; the support frame is sleeved on the top of the shell and fixed on the slider of the linear guide rail; the bracket is located directly below the support frame, and the two ends of the bracket are respectively connected with the two ends of the support frame through two telescopic cylinders; the supporting plate is horizontally fixed on the top of the bracket; the ultrasonic sensor is installed on the side wall of the bracket.

[0011] The beneficial effects produced by the above further technical solutions are that the whole composed of the support frame, the bracket and the two telescopic cylinders is surrounded on the shell, which does not affect the normal conveying of the empty bottle, when the bottle is found to be stuck, the telescopic cylinder drives the bracket to move upward, and the supporting plate lifts the stuck bottle, and the two sides of the neck of the stuck bottle return to the bottle neck sliding way for normal conveying.

[0012] Further, the cylinder body of each telescopic cylinder is installed on the side wall of the support frame through a fixing frame and bolts, and the telescopic rod of each telescopic cylinder is fixedly connected with the bracket.

[0013] The beneficial effects produced by the above further technical solutions are that the up-down position of the telescopic cylinder and the bracket at the bottom of the telescopic cylinder can be adjusted, so as to adapt to the conveying of empty bottles of different heights and sizes.

[0014] Further, a rubber pad is laid on the top plane of the supporting plate.

[0015] The beneficial effects produced by the above further technical solutions are that damage to the empty bottle during lifting is avoided.

[0016] Further, guide strips are laid on the two sides of the bottle neck sliding way, and the guide strips comprise an arc segment, a horizontal segment and a vertical support segment connected in sequence.

[0017] The beneficial effects produced by the above further technical solutions are that the arc segment design can reduce the contact area between the neck of the empty bottle and the guide strip, reduce the friction, and increase the smoothness of conveying, and the horizontal segment and the vertical support segment design can reduce the possibility of the neck of the empty bottle sliding out.

[0018] Further, baffle plates are installed on the two sides of the bottom of the shell in parallel, and the baffle plates are located on the inner side of the lifting assembly.

[0019] The beneficial effect of adopting the above-mentioned further technical solution is to minimize the tilting of empty bottles during the transportation process. Attached Figure Description
