[0025] The fixed clamping part includes a fixed clamping component, which is arranged corresponding to the movable clamping component. The bottom end of the fixed clamping component is hinged with a swing rod 9, which is arranged corresponding to the fixed plate 18. The bottom end of the fixed clamping component is provided with a sensing component, which is arranged corresponding to the swing rod 9. The sensing component and the driving component are both electrically connected to the controller.

[0026] In this embodiment, the fixed clamping part and the movable clamping part are respectively fixedly mounted on the two side clamping plates on the opening and closing mechanism of the automatic production line body. The packaging bag is conveyed to the opening and closing mechanism through the conveying structure of the automatic production line body. The opening and closing mechanism drives the two side clamping plates to make the fixed clamping part and the movable clamping part close to each other, and tightens and fixes the opening of the packaging bag through the movable clamping assembly and the fixed clamping assembly. The bag is transferred to the sealing process and the production batch printing flow of the post-process through the opening and closing mechanism. When the sensing component senses that the packaging bag is an empty bag, the sensing component transmits a signal to the controller. The controller controls the driving component to drive the movable clamping component to separate from the fixed clamping component, and the empty bag falls off, thereby realizing the online removal of empty bags.

[0027] The utility model can realize online empty bag rejection, prevent the empty bags from flowing to the subsequent process and causing processing waste, replace manual rejection, and reduce production costs.

[0028] Furthermore, the driving assembly includes a mounting plate 25, a telescopic member is fixedly mounted on the top of the mounting plate 25, the telescopic member is in transmission cooperation with the movable clamping assembly, the fixed plate 18 is fixedly mounted on the bottom of the mounting plate 25, and the telescopic member is electrically connected to the controller.

[0029] The movable clamping assembly is driven to move by the expansion and contraction of the provided telescopic member, thereby realizing the abutment and separation of the movable clamping group and the fixed clamping assembly.

[0030] Furthermore, the movable clamping assembly includes a slide rail 2 13 fixedly connected to the telescopic end of the telescopic member, and two sliders 2 14 are slidably connected to the slide rail 2 13. The side of the slider 2 14 away from the telescopic member is fixedly connected to a clamping block 24, and the clamping block 24 is arranged corresponding to the fixed clamping assembly.

[0031] Furthermore, the fixed clamping assembly includes a slide rail 3, and two sliders 4 are slidably connected to one side of the slide rail 3 near the clamping block 2 24. The end of the slider 4 near the clamping block 24 is fixedly connected to the clamping block 5. The clamping block 5 is arranged corresponding to the clamping block 24. The bottom end of the slide rail 3 is fixedly installed with a bracket 19, and the top end of the swing rod 9 is hinged on the bracket 19.

[0032] By adjusting the distance between the two sliders 14 and correspondingly adjusting the distance between the two sliders 1 4 , packaging bags with different bag widths can be clamped.

[0033] Furthermore, the sensing component includes two mounting blocks 1 fixedly connected to the side of the slide rail 3 away from the slider 4, a sensor 22 is installed on one mounting block 1, the sensor 22 is electrically connected to the controller, the sensor 22 is arranged corresponding to the swing rod 9, and a spring fixed shaft 21 is fixedly connected to the side of the other mounting block 1 close to the swing rod 9, a spring fixed shaft 1 20 is fixedly connected to the top of the swing rod 9, and the spring fixed shaft 1 20 and the spring fixed shaft 2 21 are elastically connected by a spring 23.

[0034] In this embodiment, the sensor 22 is a proximity sensor.

[0035] In the initial state, after the packaging bag containing food is clamped by the clamping block 1 5 and the clamping block 2 24, due to the certain volume of the food, under the abutment of the fixed plate 18, the volume of the food causes the swinging rod 9 to overcome the elastic force of the spring 23 and move away from the fixed plate 18 and rotate. At this time, the swinging rod 9 is right in front of the sensor 22. In this state, the cylinder 15 is in an extended state; and when the packaging bag is missing food, the swinging rod 9 is reset under the reaction force of the spring 23, and the sensor 22 transmits a signal to the controller. The controller controls the solenoid valve to control the on and off of the air path, and the cylinder 15 contracts, so that the slide rail 2 13 drives the slider 2 14 and the clamping block 2 24 to separate from the clamping block 1 5, and the empty bag falls, thereby realizing the removal of the empty bag.

[0036] Furthermore, in order to improve the stability of clamping the packaging bag, elastic pads 6 are fixedly connected to the side walls of the second clamping block 24 and the opposite side walls of the first clamping block 5.

The two guide rods 12 slide in cooperation with the linear bearings 11.

[0038] The online empty bag detection and rejection device provided by the present invention has the following working principles: when in use, the fixed clamping part and the movable clamping part are respectively fixedly mounted on the two side clamping plates of the opening and closing mechanism of the automatic production line body, the packaging bag is transmitted to the opening and closing mechanism through the transmission structure of the automatic production line body, and the opening and closing mechanism drives the two side clamping plates to make the fixed clamping part and the movable clamping part approach each other, so that the two sides of the opening of the packaging bag are clamped between the clamping block 1 5 and the clamping block 2 24. In the initial state, since the food occupies a certain volume in the packaging bag, under the abutment of the fixed plate 18, the food causes the swing rod 9 to overcome the elastic force of the spring 23 and move away from the fixed plate 18 And rotate, at this time the swing arm 9 is right in front of the sensor 22. In this state, the controller receives the information transmitted by the sensor 22 and controls the solenoid valve to extend the cylinder 15. When the packaging bag leaks food, the swing arm 9 is reset under the reaction force of the spring 23. The sensor 22 senses the position change of the swing arm 9 and transmits the data to the controller. The controller controls the solenoid valve to control the on and off of the air path, so that the cylinder 15 contracts, thereby realizing that the slide rail 2 13 drives the slider 2 14 and the clamping block 2 24 to separate from the clamping block 1 5, and the empty bag falls, thereby realizing online detection and rejection of the empty bag.
