Description

Technical Field

[0001] The utility model relates to the technical field of carton bottom sealing machines, in particular to an automatic carton bottom forming and sealing machine. Background Art

[0002] Cardboard boxes are widely used packaging products in modern society. Before placing items in a carton, the carton boards need to be folded and sealed at the bottom. This is usually done with tape, staples, or other methods. Using an automatic carton bottom forming and sealing machine can significantly improve packaging efficiency, reduce labor costs, and ensure consistent sealing quality.

[0003] When using an automatic carton bottom sealing machine to seal the bottom of a carton, the carton is moved over the conveyor roller of the machine body to the rotating roller with tape. The tape is stuck to the bottom as the carton moves to complete the bottom sealing. When the carton moves to the tape roller, one end of the carton may be lifted up, resulting in poor bottom sealing effect or failure of the bottom sealing. Utility Model Content

[0004] The utility model aims to solve the problem that when the carton moves to the tape roller, one end of the carton may be tilted, resulting in poor bottom sealing effect or bottom sealing failure, and proposes an automatic carton forming and bottom sealing machine.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic carton forming and bottom sealing machine, comprising a frame, the top of the frame is rotatably connected to a plurality of rollers, the top of the frame is provided with two groups of conveying devices, the conveying device is composed of a driving motor, a casing and a rubber conveyor belt, the outer surface of the frame is provided with a bottom sealing mechanism, the bottom sealing mechanism is composed of a tape roller for winding tape and an electric telescopic cutting knife for cutting the tape, the top of the frame is provided with a positioning device, the positioning device comprises a plurality of slot rods, the bottom ends of two of the slot rods are fixedly connected to the top end of the casing of a conveying device, the inner wall of the slot rod is slidably connected to a sliding rod, the top end of the sliding rod is fixedly connected to a rectangular rod, one side of the rectangular rod is rotatably connected to a plurality of cylindrical blocks, one side of the top end of the casing of the conveying device is rotatably connected to a screw, and the outer surface of the screw is threadedly connected to one side of the inner wall of the rectangular rod.

[0006] The effect achieved by the above components is: by setting cylindrical blocks, when using an automatic forming bottom sealing machine to seal the bottom of the carton, you can first push the screw to rotate on one side of the two conveying devices according to the height of the carton, so that the rectangular rod moves up and down on the outer surface of the screw, driving the sliding rod to slide up and down on the inner wall of the groove rod to adjust the height position of the rectangular rod and the cylindrical block. When the carton passes between the two conveying devices, the top end will move on the surface of several cylindrical blocks on one side of the two rectangular rods and drive the cylindrical blocks to rotate. The cylindrical blocks are used to limit the position of the carton between the conveying devices to avoid the carton from tilting up in some parts during the movement, which affects the bottom sealing effect of the bottom end of the carton.

[0007] Preferably, the top end of the screw is fixedly connected to an operating block, and the outer surface of the operating block is fixedly connected to a plurality of protrusions.

[0008] The effect achieved by the above components is that by holding the protrusion on the outer surface of the operating block, the operating block and the screw can be more conveniently controlled to rotate and adjust the height position of the sliding rod and the rectangular rod.

[0009] Preferably, both sides of the bottom end of the rectangular rod are fixedly connected with oblique rods, and one end of the oblique rod away from the rectangular rod slides on one side of the groove rod.

[0010] The effect achieved by the above components is: when the screw is rotated to control the rectangular rod to move up and down, one end of the oblique rod on both sides of the bottom end of the rectangular rod will slide on one side of the slot rod, further limiting the angle between the rectangular rod, the slot rod and the frame, and avoiding the angle deviation at both ends of the rectangular rod as much as possible.

[0011] Preferably, a positioning ring is fixedly connected to one side of the top end of the casing of the conveying device, and the outer surface of the screw rotates on the inner wall of the positioning ring.

[0012] The effect achieved by the above components is: when the screw is rotated, the outer surface of the screw will rotate on the inner wall of the positioning ring. The positioning ring can further limit the angle between the screw and the conveying device, thereby avoiding as much as possible the deviation of the angle of the screw during rotation to affect normal use.

[0013] Preferably, a collecting device is provided at one end of the frame, and the collecting device includes a collecting box. A movable wheel is provided at the bottom end of the collecting box. Two rectangular blocks are fixedly connected to one side of the collecting box. Two slots are opened at one end of the frame. The size and shape of the outer surface of the rectangular block are adapted to the size and shape of the inner wall of the slot.

[0014] The effect achieved by the above components is: when using the bottom sealing machine, the collection box can be pushed to move the position through the moving wheels at the bottom to insert the two rectangular blocks at one end into the two slots at one end of the frame, so that the collection box is fixed on one side of the frame. After passing between the two conveying devices and the bottom sealing mechanism, the cartons with the bottom sealed will enter the interior of the collection box for centralized collection, which is convenient for centralized transportation and improves the convenience when using the bottom sealing machine.

[0015] Preferably, a guide plate is fixedly connected to the top of the collection box, and one side of the outer surface of the guide plate is an inclined surface.

[0016] The effect achieved by the above components is that the cartons output through the rack will enter the interior of the collection box through the guide plate. The guide plate can make the cartons enter the interior of the collection box more smoothly and are not easily stuck at the connection between the collection box and the rack.

[0017] Preferably, a plurality of convex strips are fixedly connected to the upper and lower sides of the rectangular block, and the convex strips are rubber strips.

[0018] The effect achieved by the above components is that the rubber ridges can increase the friction between the rectangular block and the inner wall of the slot when the rectangular block is inserted into the slot, making it difficult for the rectangular block to accidentally fall off from the slot.

[0019] Preferably, a pull rod is fixedly connected to one side of the collection box, and the cross-section of the pull rod is U-shaped.

[0020] The effect achieved by the above components is that the movement position of the collection box can be more conveniently controlled by holding the outer surface of the U-shaped pull rod.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] In the utility model, a positioning device is provided and the height positions of the rectangular rods and the cylindrical blocks are adjusted by rotating the screw, so that the carton moves on the surfaces of several cylindrical blocks on one side of the two rectangular rods and drives the cylindrical blocks to rotate. The position of the carton between the conveying devices is restricted by the cylindrical blocks, and it is avoided as much as possible that part of the carton is tilted during the movement, which affects the bottom sealing effect of the carton.
