Description

Technical Field

[0001] The utility model belongs to the field of product box sealing, in particular to a gap feeding device for product box sealing. Background Art

[0002] In the process of sealing the boxes and dividing the boxes, the newly delivered boxes need to be temporarily detained. After the box dividing work at the sealing station is completed to a certain extent, the temporarily detained boxes will be transported to the sealing station. In the process of temporarily detaining the newly delivered boxes, the conveying assembly at the temporary detention location will be flipped over so that the temporarily detained boxes are lower than the conveying plane, and the boxes to be sealed will be blocked and temporarily detained. However, after the conveying assembly is flipped over and the boxes are blocked, the boxes on the conveying assembly will be squeezed under the action of gravity, and the boxes that are blocked first on the conveying assembly in the flipped state will bear the weight of the boxes delivered later, which is easy to cause squeezing damage to the boxes that are blocked first. Summary of the Invention

[0003] In view of this, the utility model aims to propose a gap feeding device for product box sealing, so as to solve the technical problem that after the conveying component is flipped over and the box is blocked, the box on the conveying component will be squeezed under the action of gravity, and the box that is first blocked on the conveying component in the flipped state will bear the weight of the box conveyed from behind, which is easy to cause squeezing damage to the box that is first blocked.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0005] A gap feeding device for product box sealing includes a support frame, the support frame has an installation cavity, and also includes: a flip conveying assembly, the flip conveying assembly includes a flip frame and a flip adjustment assembly, the flip frame is rotatably connected to the inside of the installation cavity, a plurality of second conveying rollers are rotatably arranged inside the flip frame, and the flip adjustment assembly is used to adjust the flip angle of the flip frame; a clamping assembly, the clamping assembly includes two clamping claws, the two clamping claws are used to clamp and support the subsequent box on the surface of the second conveying roller and which squeezes the box that was first blocked.

[0006] It should be understood that when the box needs to be temporarily retained, the flip frame is adjusted to flip through the flip adjustment component, and the height of the first box support that is retained first is lowered, and it is temporarily retained by the support frame. The newly conveyed second box will stick to the first box under the action of gravity and the conveying action of the second conveying roller, causing extrusion. At this time, the second box in the flipped state is clamped and positioned through the clamping component to achieve support for the second box, thereby reducing the extrusion force of the second box on the first box, which is beneficial to reduce the extrusion damage to the first box.

[0007] Furthermore, each of the two clamping jaws includes an arcuate segment and a horizontal segment. The arcuate segment passes through the gaps between adjacent second conveyor rollers among the plurality of second conveyor rollers. Two support rods are slidably connected to the bottom ends of the arcuate segments, and the ends of the two support rods are fixedly connected to the inner wall of the mounting cavity. The clamping jaws also include a linkage assembly, which includes two linkage rails fixedly connected to the surfaces of the two clamping jaws and symmetrically arranged with respect to the flip frame. The linkage rails include a guide rail and a maintenance rail. A linkage pin is slidably disposed within each of the guide rails. A support member is fixedly connected to the surface of each linkage pin, and the support member is fixedly connected to the inner wall of the flip frame. It should be understood that during the flip frame flipping process, the support member drives the linkage pin to move within the linkage rail. As the linkage pin moves within the guide rail, it pushes the linkage rails, causing the two linkage rails to approach each other. When the two linkage pins move to the maintenance rails, the second box is clamped and maintained. It should be noted that by dividing the clamping jaws into an arcuate segment and a horizontal segment, the second conveyor rollers are avoided, and the clamping area of ​​the second box is increased.

[0008] Furthermore, the support member is a gas spring, which is fixedly mounted on the inner side wall of the flip frame, and the telescopic end is fixedly connected to the linkage pin. It should be understood that by providing the gas spring, when the support member is in the track maintenance position, the gas spring is compressed, exerting an elastic support force on the clamping claw, thereby maintaining the clamping support for the second box while avoiding rigid clamping.

[0009] Compared with the prior art, the gap feeding device for product box sealing described in the present invention has the following beneficial effects:

[0010] The utility model discloses a gap feeding device for sealing products. The flipping of the flipping frame is adjusted by a flipping adjustment component, and the height of the first box body supported by the support frame is lowered, and the box body is temporarily retained by the support frame. The newly conveyed second box body will stick to the first box body under the conveying action of gravity and the second conveying roller, causing extrusion. At this time, the second box body in the flipped state is clamped and positioned by the clamping component to achieve support for the second box body, thereby reducing the extrusion force of the second box body on the first box body, which is beneficial to reduce the extrusion damage to the first box body.

[0011] The utility model discloses a gap feeding device for sealing a product. By arranging a gas spring, when the support member is on the maintenance track, the gas spring is compressed, and an elastic supporting force is exerted on the clamping claw, thereby maintaining the clamping support for the second box body and avoiding rigid clamping.
