Description

Technical Field

[0001] This utility model relates to a packaging bag placement mechanism in packaging equipment, and particularly to a flat bag storage mechanism for a packaging machine. Background Technology

[0002] Currently, the bag storage mechanism in packaging equipment is a single-station design. This means that operators or robots place stacked packaging bags in the storage area, and then a suction mechanism (such as a suction cup) transfers them. Due to this single-station design, when the packaging bags in this station are completely used up (i.e., completely transferred by the suction cup), it is necessary to pause the operation of subsequent equipment to replenish some packaging bags in this station, thus affecting the operating efficiency of the equipment.

[0003] Examples include the Chinese patent "Storage mechanism compatible with both handle-fastening and non-handle-fastening packaging bags" (Announcement No. CN221776199U) and "A packaging machine suitable for the retail and takeaway industry" (Announcement No. CN214452272U). Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to propose a flat bag storage mechanism for a packaging machine. The flat bag storage mechanism of this packaging machine is reasonably designed and conducive to improving the working efficiency of the equipment.

[0005] This utility model is implemented using the following solution.

[0006] The packaging machine of this utility model has a flat bag storage mechanism, characterized in that: it includes a circulating chain conveyor belt horizontally installed on the frame, and multiple bag pushers are vertically installed at equal intervals on the circulating chain conveyor belt. The upper surface of the circulating chain conveyor belt is provided with multiple sets of horizontal bag storage stations for placing stacked packaging bags and a set of bag preparation stations. The circulating chain conveyor belt is driven by a first motor, and each time the first motor works, the bag pusher moves one station forward.

[0007] Preferably, the frame is provided with a base frame and a circulating chain conveyor belt on the base frame. Multiple support legs are provided below the base frame. The left and right sides of the upper surface of the base frame are respectively provided with roller seats, rotating rollers rotatably connected to the roller seats, and two sprockets fixed at intervals on the rotating rollers. Each of the two sprockets on both sides is equipped with a chain. The first motor drives a rotating roller to rotate. The multiple pusher rods are fixed parallel to each other at equal intervals on the chain.

[0008] Preferably, the upper surface of the base frame is provided with multiple vertical support columns. At the horizontal bag storage station, a horizontal support plate for packaging bags is fixedly installed on the upper surface of the multiple vertical support columns. At the bag preparation station, a horizontal perforated plate is fixedly installed on the upper surface of the multiple vertical support columns. The horizontal support plate for packaging bags and the horizontal perforated plate are located directly above the base frame, and both the horizontal support plate for packaging bags and the horizontal perforated plate are provided with strip-shaped seams to avoid the operation of the bag pusher rod.

[0009] Preferably, the aforementioned horizontal perforated plate is provided with multiple racetrack-shaped holes, and a number of racetrack-shaped holes are fixedly installed with baffles for limiting the packaging bags in the bag preparation station.

[0010] Preferably, the strip seam in the aforementioned horizontal storage bag station extends through the beginning and end of the horizontal support plate of the packaging bag, and the end of the strip seam on the horizontal support plate of the packaging bag is connected to the strip seam in the horizontal perforated plate.

[0011] The working principle of the flat bag storage mechanism of this packaging machine is as follows: the operator places multiple stacks of packaging bags on multiple sets of horizontal bag storage stations at one time. The first motor drives the circulating chain conveyor belt, which is equipped with pusher rods at intervals. These pusher rods can transport the prepared packaging bags from the horizontal bag storage stations to the bag preparation stations for equipment to pick up the bags (such as by suction cup mechanism). This allows the operator to place multiple stacks of packaging bags at once, reducing the number of operations; and it does not require stopping the operation of subsequent equipment, thus improving the working efficiency of the equipment.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] The packaging machine of this utility model has a flat bag storage mechanism including a circulating chain conveyor belt A2 horizontally mounted on a frame A1. Multiple bag pushers A3 are vertically installed at equal intervals on the circulating chain conveyor belt A2. The upper surface of the circulating chain conveyor belt A2 is provided with multiple sets of horizontal bag storage stations A5 for placing stacked packaging bags A4 and a set of bag preparation stations A6. The circulating chain conveyor belt is driven by a first motor A7. Each time the first motor works, the bag pusher A3 moves one station, that is, moves one unit along the running direction of the circulating chain conveyor belt A2 (this unit represents moving from one horizontal bag storage station to the next horizontal bag storage station, or from the horizontal bag storage station to the bag preparation station).

[0018] Specifically, the frame A1 is equipped with a base frame A8 and a circulating chain conveyor belt A2 on the base frame. Multiple support legs A10 are provided below the base frame A8. The left and right sides of the upper surface of the base frame are respectively equipped with roller seats A11, rotating rollers A12 rotatably connected to the roller seats, and two sprockets A13 fixed at intervals on the rotating rollers. Chains A14 are installed on the two sprockets A13 on both sides. The first motor drives a rotating roller to rotate. Multiple pusher rods A3 are fixed parallel to each other at equal intervals on the chain A14.

[0019] To ensure a reasonable design and smooth pushing of the packaging bags, multiple vertical support columns A15 are provided on the upper surface of the aforementioned base frame A8. At the horizontal bag storage station, a horizontal support plate A16 for the packaging bags is fixedly installed on the upper surface of the multiple vertical support columns A15. At the bag preparation station, a horizontal perforated plate A17 is fixedly installed on the upper surface of the multiple vertical support columns. The horizontal support plate and the horizontal perforated plate are located directly above the base frame, and both the horizontal support plate and the horizontal perforated plate are provided with strip seams A18 to avoid the movement of the bag pusher. The strip seam in the horizontal bag storage station runs through the beginning and end of the horizontal support plate, and the end of the strip seam on the horizontal support plate connects with the strip seam in the horizontal perforated plate.

[0020] The horizontal perforated plate has multiple racetrack-shaped holes A19, and some of these racetrack-shaped holes are fixedly installed with retaining strips A20 for limiting the packaging bags in the bag preparation station.

[0021] The working principle of the flat bag storage mechanism of this packaging machine is as follows: the operator places multiple stacks of packaging bags on multiple sets of horizontal bag storage stations at one time. The first motor drives the circulating chain conveyor belt, which is equipped with pusher rods at intervals. These pusher rods can transport the prepared packaging bags from the horizontal bag storage stations to the bag preparation stations for equipment to pick up the bags (such as by suction cup mechanism). This allows the operator to place multiple stacks of packaging bags at once, reducing the number of operations; and it does not require stopping the operation of subsequent equipment, thus improving the working efficiency of the equipment.

[0022] When the equipment is in operation, the first motor drives the chain to rotate a set stroke. The pusher bar on the chain moves each stack of packaging bags one step towards the bag preparation station, so that there is a stack of packaging bags available for retrieval at the bag preparation station. After the packaging bags at the bag preparation station are used up, the first motor drives the pusher bar again, pushing the packaging bags at the horizontal bag storage station one stroke towards the bag preparation station, so that there are packaging bags available for use at the bag preparation station again. Since the chain is a circulating type, the pusher bar on the chain can also be reused.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
