In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0022] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] The present application relates to a packaging bag conveying device, Figure 1 The packaging bag conveying device includes a rejecting mechanism and a feeding mechanism 3000, combined with the attached Figure 2 The rejecting mechanism has a feeding trough 1100, and the feeding trough 1100 has a rejecting notch 1101. Furthermore, the feeding mechanism 3000 has a conveyor belt, and the packaging bags conveyed by the feeding mechanism 3000 enter the feeding trough 1100. In the feeding trough 1100, if the packaging bags are stacked, they do not meet the feeding requirements. These packaging bags that do not meet the feeding requirements fall from the rejecting notch 1101, thereby completing the rejection of the packaging bags, and the packaging bags that meet the feeding requirements are conveyed from the rejecting mechanism to the next process.

[0024] Furthermore, combined with Figure 1The packaging bag conveying equipment includes a return material mechanism 4000, which has a conveyor belt. The packaging bags rejected by the rejection mechanism fall from the rejection gap 1101 to the return material mechanism 4000. The return material mechanism 4000 conveys the rejected packaging bags to the feeding mechanism 3000 so that the rejected packaging bags enter the feeding trough 1100 again.

[0025] Combined with Figure 1 The feeding mechanism 3000 includes a feeding hopper 3100 , and the returning mechanism 4000 extends to the feeding hopper 3100 , and the returning mechanism 4000 transports the packaging bags to the feeding hopper 3100 .

[0026] As an implementation method, in combination with the attached Figure 1 The packaging bag conveying equipment includes a feeding mechanism 5000, which has a conveyor belt. The packaging bags that meet the feeding requirements on the rejection mechanism are conveyed to the feeding mechanism 5000, and the feeding mechanism 5000 conveys the packaging bags to the next process.

[0027] The other structures and operations of the packaging bag conveying equipment have been recorded in the relevant technology for ordinary technicians in this field and will not be described in detail here. The structure of the rejection mechanism will be introduced below.

[0028] The present application relates to a rejection mechanism, combined with the attached Figure 1 and attached Figure 2 The rejection mechanism includes a vibrating conveying component 1000 and a blowing component 2000. The packaging bags enter the vibrating conveying component 1000. The vibrating conveying component 1000 conveys the packaging bags by vibration and can disperse the packaging bags by vibration so that the packaging bags are not stacked. The packaging bags are conveyed one by one. The blowing component 2000 blows down the packaging bags in the vibrating conveying component 1000 that do not meet the feeding requirements, thereby completing the rejection of the packaging bags.

[0029] It is understandable that the blowing assembly 2000 is connected to the air source and combined with the attached Figure 2 The blowing assembly 2000 includes an air nozzle 2100, and the air nozzle 2100 blows a high-pressure airflow toward the stacked packaging bags to make the stacked packaging bags fall.

[0030] Combined with Figure 2 The vibration conveying assembly 1000 includes a feeding trough 1100, an air nozzle 2100 is arranged above the feeding trough 1100, and a rejection notch 1101 is arranged on the side wall of the feeding trough 1100. The air nozzle 2100 corresponds to the position of the rejection notch 1101, and the air nozzle 2100 blows air toward the rejection notch 1101 to make the stacked packaging bags passing through the rejection notch 1101 fall from the rejection notch 1101.

[0031] It should be noted that the vibration conveying assembly 1000 includes a vibrator, and the feeding trough 1100 is connected to the vibrator. Under the action of the motor of the vibrator, the feeding trough 1100 vibrates to convey the packaging bag.

[0032] Furthermore, the elimination notch 1101 is located near the outlet of the feeding trough 1100 so as to extend the conveying path of the packaging bags in the feeding trough 1100, thereby allowing the packaging bags in the feeding trough 1100 to be spread out as much as possible during the vibration conveying process, thereby reducing the stacking of packaging bags, reducing the packaging bags that do not meet the feeding requirements, and improving the efficiency of packaging bag conveying.

[0033] Combined with Figure 3 A baffle 1102 is provided at one end of the feeding trough 1100 away from the outlet, and the baffle 1102 seals the port of the feeding trough 1100 to prevent the packaging bag from falling from this end, thereby ensuring that the packaging bag is transported from the feeding trough 1100 to the end where the outlet is located.

[0034] As an implementation method, in combination with the attached Figure 2 and attached Figure 3 The feeding trough 1100 has an inclined side wall, and the packaging bag entering the feeding trough 1100 is conveyed along the side wall in an inclined posture. Specifically, the feeding trough 1100 is configured as a V-shaped trough, and the cross section of the feeding trough 1100 is in a V-shaped shape.

[0035] Combined with Figure 2 and attached Figure 3 The material removal notch 1101 is arranged on the inclined side wall of the feeding trough 1100, and a part of the inclined side wall of the feeding trough 1100 is hollowed out to form the material removal notch 1101, and a part of the side wall is retained near the bottom for supporting the inclined packaging bag.

[0036] It is understandable that at the rejection notch 1101, the upper part of the packaging bag is suspended in the air, and the lower part contacts the inclined side wall of the feeding trough 1100. When the packaging bag is acted upon by the high-pressure gas of the air nozzle 2100, the packaging bag falls from the rejection notch 1101.

[0037] Furthermore, combined with Figure 2 and attached Figure 3 , the side wall where the rejecting notch 1101 is located in the feeding trough 1100 is set as a plane side wall, so that the angle of inclination of the packaging bag when it is transported along the side wall is stable. Specifically, if the side wall of the feeding trough 1100 is set as a plane side wall, the inclination angle of the side wall is consistent, and the inclination angle of the packaging bag before it moves to the rejecting notch 1101 and the inclination angle when it moves to the rejecting notch 1101 are the same, so as to avoid the posture of the packaging bag changing when it moves to the position where the rejecting notch 1101 is located, so as to prevent the packaging bag from falling from the rejecting notch 1101 by mistake.

[0038] In some examples, along the extension direction of the length of the feeding trough 1100, one of the side walls of the feeding trough 1100 has a larger outward inclination angle than the other side wall, so that each packaging bag is inclined to the same side of the feeding trough 1100. Figure 2 and attached Figure 3 The blanking notch 1101 is arranged on the side wall with a larger inclination angle.

[0039] In some examples, the Figure 2 and attached Figure 3 Among the side walls on both sides of the feeding trough 1100, one side wall is a vertical side wall and the other side wall is an inclined side wall.

[0040] It should be noted that if the packaging bags can be tilted toward the side walls on both sides of the feeding trough 1100, the air nozzle 2100 needs to change direction when removing the stacked packaging bags, which affects the removal efficiency and increases the manufacturing cost of the equipment.

[0041] As an implementation mode, at least two feeding troughs 1100 are provided, and the feeding troughs 1100 are arranged side by side to increase the capacity of the rejection mechanism, and at the same time, multiple feeding troughs 1100 are vibrating and conveying the packaging bags.

[0042] Accordingly, at least two air nozzles 2100 are provided, and each air nozzle 2100 is arranged at intervals along the direction in which each feeding trough 1100 is arranged side by side. It can be understood that the number of air nozzles 2100 is the same as that of feeding trough 1100, and the air nozzles 2100 correspond to the feeding trough 1100 one by one.

[0043] Combined with Figure 2 The blowing assembly 2000 includes a first bracket 2200, which is disposed above the vibration conveying assembly 1000, connected to the frame of the packaging bag conveying device, and the air nozzle 2100 is connected to the first bracket 2200. On the first bracket 2200, the air nozzles 2100 are distributed at intervals.

[0044] As an implementation method, at least two parallel feeding troughs 1100 are formed by continuously bending a plate, and the plate is made of a steel plate or an aluminum plate. Figure 2 and attached Figure 3 The plate is continuously bent to form a plurality of V-shaped grooves, which are used as feeding troughs 1100 respectively.

[0045] Furthermore, a notch 1101 for removing blanks is simultaneously formed on the side wall of each feeding trough 1100 by cutting. Figure 2 and attached Figure 3The material removal notch 1101 is set on the side wall at the outlet of the feeding trough 1100, and the side wall of the feeding trough 1100 is cut along the length extension direction of the feeding trough 1100. The side wall of the feeding trough 1100 is cut along the direction perpendicular to the length extension direction of the feeding trough 1100, so that the material removal notch 1101 can be formed on the side wall at the outlet of the feeding trough 1100.

[0046] It is understandable that when processing the feed trough 1100, multiple feed troughs 1100 are cut at the same time, and after two consecutive cuts, the removal gap 1101 can be formed at the same time, thereby improving the processing efficiency.

[0047] In some examples, in order to reduce the difficulty of processing the feed trough 1100 , at least one alternative design can be provided: at least two plates bent to form the feed troughs 1100 are combined to form a structure with more feed troughs 1100 , and each plate is bent to form at least two feed troughs 1100 .

[0048] As an embodiment, the rejection mechanism includes an image acquisition component, which includes a camera, and the camera is used to take photos of the packaging bags in the feeding trough 1100 and upload the photos to the host computer. The host computer identifies and determines whether the packaging bags are stacked. If so, the host computer starts the blowing component 2000 corresponding to the feeding trough 1100.

[0049] Furthermore, the rejection mechanism includes an in-place sensor, which is arranged near the rejection notch 1101 and is used to detect whether the packaging bag reaches the rejection notch 1101. The packaging bag reaching the rejection notch 1101 triggers the in-place sensor, which generates a signal and uploads it to the host computer, which starts the image acquisition component to take a picture of the packaging bag.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
