DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] For example, see Figures 1 to 5 The present embodiment provides an empty bottle leak detection device for detergent production, comprising a conveyor frame 1, a support frame 2 is provided on one side of the conveyor frame 1, a Z-axis linear motor 3 is fixed on the top of the support frame 2, a mounting member 4 is fixed to the moving end 31 of the Z-axis linear motor 3, a gas pipeline 5 is fixed on the mounting member 4, a switching component 6 is installed on the mounting member 4, and eight abutting heads 7 are installed on the switching component 6 at equal angles;

[0023] When leak detection is performed, the empty detergent bottle to be tested is transported by the conveyor rack 1. The structure of the conveyor rack 1 is prior art and will not be described in detail again.

[0024] The switching assembly 6 includes a main shaft 61 rotatably connected to the mounting member 4 through a bearing, an end of the main shaft 61 away from the Z-axis linear motor 3 is slidably connected to a carrier plate 62, eight abutting heads 7 are fixed on the carrier plate 62 at equal angles, the abutting heads 7 include a connecting pipe 71 fixed to the carrier plate 62, a abutting plate 72 fixed to the end of the connecting pipe 71 away from the gas pipeline 5, and a abutting ring 73 fixed to the end of the connecting pipe 71 close to the gas pipeline 5, one end of the connecting pipe 71 close to the abutting ring 73 cooperates with the gas pipeline 5, a rubber sealing gasket 8 is fixed to the side of the abutting plate 72 away from the connecting pipe 71, a groove wheel 64 is fixed to the end of the main shaft 61 close to the mounting member 4, a motor 65 is fixed to the mounting member 4, a driving wheel 66 is fixed to the protruding end of the motor 65, and the driving wheel 66 cooperates with the groove wheel 64, an electric push rod 63 is fixed to the outer wall of the main shaft 61, and the protruding end of the electric push rod 63 is fixed to the outer wall of the bearing plate 62;

[0025] Before leak detection, the switching assembly 6 needs to be operated to ensure that a pressing head 7 matching the diameter of the mouth of the empty detergent bottle to be tested is rotated and switched to face directly downward;

[0026] The specific switching process is as follows. First, the electric push rod 63 is driven to extend, pushing the bearing plate 62 to slide on the main shaft 61 away from the motor 65, so that the end of the connecting pipe 71 can be pulled out from the end of the gas transmission pipeline 5, and the tightening ring 73 is separated from the end of the gas transmission pipeline 5. Then, the motor 65 is driven to rotate, driving the driving wheel 66 to rotate. Each time the driving wheel 66 rotates one circle, the grooved wheel 64 is driven to rotate 45 degrees until a required tightening head 7 rotates to face the top surface of the conveying rack 1 directly below, completing the switching work. Then, the electric push rod 63 is driven to contract, pulling the bearing plate 62 to slide on the main shaft 61, so that the end of the gas transmission pipeline 5 of a required tightening head 7 is inserted into the end of the gas transmission pipeline 5 to communicate with the gas transmission pipeline 5, and the tightening ring 73 of a required tightening head 7 is tightened against the end of the gas transmission pipeline 5;

[0027] Before the detection work, an air pump device is set up, and the air outlet end of the air pump device is connected to the air inlet end of the gas transmission pipeline 5. During the detection, when the empty bottle to be tested is conveyed by the conveying rack 1 to directly below a required tightening head 7, the Z-axis linear motor 3 drives the mounting member 4 to descend, so that the tightening plate 72 facing the empty bottle descends to press the rubber sealing washer 8 against the mouth of the empty bottle to be tested. Subsequently, the air pump device pumps air, and the gas enters the gas transmission pipeline 5, then enters the connecting pipe 71, and then enters the empty bottle for leak detection.

[0028] In summary, a plurality of tightening heads 7 with modular design are adopted, and each tightening head 7 is equipped with tightening plates 72 with different diameters. The sizes of these tightening plates 72 are precisely matched with the specifications of the mouths of various common dishwashing liquid empty bottles on the market. The switching component 6 is integrated in the device, and this component can automatically and accurately drive the corresponding tightening head 7 to rotate to the working position according to the real-time size change of the mouth of the dishwashing liquid empty bottle on the conveyor belt. This design realizes a high degree of automation in the leak detection process, and there is no need to manually replace the tightening head 7 to adapt to dishwashing liquid empty bottles with different mouth diameters.
