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 device, which comprises a bag feeding device and a material discharging component. The material discharging component puts small materials into a packaging bag. The small materials are small packaging bags or granules.

[0024] The present application relates to a bag feeding device, which comprises a bag feeding conveying assembly, wherein the bag feeding conveying assembly is used for conveying packaging bags, and a material discharge assembly is arranged above the bag feeding conveying assembly.

[0025] Furthermore, the bag feeding device includes a bag feeding supply assembly, which is arranged at the feeding end of the bag feeding conveying assembly, and the bag feeding supply assembly provides packaging bags for the bag feeding conveying assembly.

[0026] The other structures and operations of the packaging equipment and the bag feeding device 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 bag feeding conveying component will be introduced below.

[0027] The present application relates to a bag feeding conveying assembly, which includes a first conveying assembly 1000 and a second conveying assembly 2000, wherein the second conveying assembly 2000 is located on the upper side or the lower side of the first conveying assembly 1000, and both the first conveying assembly 1000 and the second conveying assembly 2000 are capable of clamping packaging bags, and both the first conveying assembly 1000 and the second conveying assembly 2000 extend along a first direction parallel to the conveying direction of the packaging bag in the bag feeding conveying assembly.

[0028] Along a second direction perpendicular to the first direction, the first conveying assembly 1000 and the second conveying assembly 2000 can be opened and closed alternately, so that the first conveying assembly 1000 clamps the packaging bag or the second conveying assembly 2000 clamps the packaging bag. It should be noted that the alternating opening and closing of the first conveying assembly 1000 and the second conveying assembly 2000 means that when the first conveying assembly 1000 is closed and clamps the packaging bag, the second conveying assembly 2000 opens and releases the packaging bag, and when the second conveying assembly 2000 is closed and clamps the packaging bag, the first conveying assembly 1000 opens and releases the packaging bag.

[0029] Further, the bag feeding conveying assembly includes a bag feeding conveying driving assembly 3000, and the bag feeding conveying driving assembly 3000 is connected to the second conveying assembly 2000. In the first direction, the position of the first conveying assembly 1000 is fixed, and under the drive of the bag feeding conveying driving assembly 3000, the second conveying assembly 2000 can move parallel to the first direction to move the packaging bag in the first conveying assembly 1000 forward.

[0030] Specifically, the second conveying assembly 2000 clamps the Mth packaging bag, the first conveying assembly 1000 releases the Mth packaging bag, the second conveying assembly 2000 moves forward a set distance L parallel to the first direction, the Mth packaging bag moves forward to a set position, the first conveying assembly 1000 clamps the Mth packaging bag, the second conveying assembly 2000 releases the Mth packaging bag, and the second conveying assembly 2000 moves backward a set distance L parallel to the first direction.

[0031] It can be understood that, in the bag feeding conveying assembly, the first conveying assembly 1000 and the second conveying assembly 2000 are alternately opened and closed, and the second conveying assembly 2000 reciprocates within a set distance L, thereby realizing the forward conveyance of the packaging bags one by one.

[0032] The first conveying assembly 1000 includes at least two first clamping assemblies, which are arranged at intervals along the first direction.

[0035] As an embodiment, the first clamping assembly includes two first clamps 1100, and the two first clamps 1100 are paired. Along the second direction, the two first clamps 1100 are arranged at intervals, and the ends of the first clamps 1100 are used to abut against the outer side of the packaging bag. The packaging bag to be clamped by the first conveying assembly 1000 is located between the two first clamps 1100 of the first clamping assembly. The two first clamps 1100 are close to or away from each other, so as to clamp or release the packaging bag.

[0036] Furthermore, to prevent the first clamp 1100 from damaging the packaging bag, the first clamp assembly is designed such that the first clamp 1100 applies elastic pressure to the outer side of the packaging bag. Specifically, a spring is disposed inside the end of the first clamp 1100, or a soft cushion is disposed at the end of the first clamp 1100.

[0037] As an embodiment, the first conveying assembly 1000 includes two first support beams 1200, the first support beams 1200 extend parallel to the first direction, the two first support beams 1200 are spaced apart along the second direction, and the two first clampers 1100 of the first clamping assembly are respectively arranged on the two first support beams 1200.

[0038] It can be understood that the two first support beams 1200 move closer to or farther away from each other along the second direction so that the first clamping assembly clamps or releases the packaging bag, and each first clamping assembly in the first conveying assembly 1000 can synchronously clamp or release the packaging bag.

The two first clamping drive connecting rods 1303 respectively drive the two first clamping movable seats 1301 to move closer to or away from each other, and then drive the two first support beams 1200 to move closer to or away from each other, thereby realizing the first conveying component 1000 clamping or releasing the packaging bag.

[0044] In some examples, in order to enable the first conveying assembly 1000 to open and close smoothly, at least two first clamping drive assemblies 1300 are provided, and the first clamping drive assemblies 1300 are arranged at intervals along the first direction.

The packaging bag to be clamped by the second conveying assembly 2000 is located between the two second clamps 2100 of the second clamping assembly, and the two second clamps 2100 are close to or away from each other, so as to clamp or release the packaging bag.

[0048] Furthermore, in order to prevent the second clamper 2100 from damaging the packaging bag, the second clamping assembly is designed so that the second clamper 2100 applies elastic pressure to the outer side of the packaging bag. Specifically, a spring is provided inside the end of the second clamper 2100, or a cushion is provided at the end of the second clamper 2100.

[0049] As an embodiment, the second conveying assembly 2000 includes two second support beams 2200, which extend parallel to the first direction. The two second support beams 2200 are spaced apart along the second direction, and the two second clampers 2100 of the second clamping assembly are respectively arranged on the two second support beams 2200.
