Description

Technical Field

[0001] This utility model relates to the field of box-opening machine technology, specifically a novel self-locking bottom high-speed box-opening machine. Background Technology

[0002] A carton opening machine is an automated device used to unfold flat cardboard box blanks that have been cut and glued to form a predetermined three-dimensional packaging box shape. It features automatic unfolding and forming operation, uses PLC control and touch screen operation, has a high degree of automation, and some models support unlimited material feeding. It is easy to operate and is widely used in packaging production lines in industries such as pharmaceuticals, food, toys, and daily chemical products.

[0003] In pharmaceutical packaging production lines, many pharmaceutical packaging boxes require two sets of equipment to complete the entire opening and locking process. Opening and locking are done independently, which not only increases the floor space occupied by the packaging production line equipment, but also increases the overall time for opening and locking, thus affecting efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel self-locking bottom high-speed box opening machine, which solves the problems of increased floor space and reduced efficiency caused by using two sets of equipment to complete the unfolding and bottom locking of pharmaceutical packaging boxes.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A novel self-locking bottom high-speed box opening machine includes a feeding component, a box opening and bottom locking component, a discharging component, and two parallel platforms. The feeding component is located on top of the upper platform and includes a small inclined platform for placing flat boxes, a large inclined platform connected between one end of the small inclined platform and the upper surface of the upper platform, and a limiting plate for limiting the flat boxes, which is located on one side of the large inclined platform, parallel to the large inclined platform, and bent downward at the lower end. Limiting guardrails for limiting the flat boxes are installed on the front and back of the small and large inclined platforms.

[0007] The platform located above is provided with a through groove for the flat cardboard box to pass through at the position between the large sloping platform and the limiting plate. Positioning clips for engaging the flat cardboard box are fixed on the lower surface of the platform above at the position around the through groove.

[0008] The flat cardboard box includes two front panels and two side panels that are parallel to each other, and the two front panels and two side panels are connected at intervals.

[0009] The platform located below is provided with a clearance groove at the position of the lower front panel of the flat cardboard box directly above. The box opening and locking assembly includes a descending and unfolding push rod fixedly installed at the bottom of the lower platform corresponding to the lower front panel of the flat cardboard box. The upper end of the piston rod of the descending and unfolding push rod is fixed with an installation plate. Multiple descending and unfolding suction cups connected to an air pump via hoses are installed on the installation plate.

[0010] The box opening and bottom locking assembly also includes a fixed guide plate fixed on one side of the clearance groove on the lower platform, and a clamping push rod installed on the other side of the clearance groove on the lower platform. The piston rod front end of the clamping push rod is fixed with a movable guide plate located on the opposite side of the fixed guide plate.

[0011] The flat cardboard box is squeezed and expanded by the movable guide clamp and the fixed guide clamp to form a three-dimensional cardboard box. The three-dimensional cardboard box includes a box panel, a box side panel, a bottom flap, a bottom locking cover, and two side flaps.

[0012] The box opening and bottom locking assembly also includes a side support push rod installed on the lower platform on the back of both sides of the three-dimensional cardboard box and with the front end corresponding to the side flap; a lower support push rod installed at the bottom of the lower platform below the back of the three-dimensional cardboard box and with the front end corresponding to the bottom flap; an upper support push rod installed at the bottom of the upper platform above the back of the three-dimensional cardboard box and with the front end corresponding to the bottom locking cover; and a support block fixed to the front end of the piston rods of the side support push rod, the lower support push rod, and the upper support push rod.

[0013] The feeding assembly includes a rodless cylinder that is vertically installed at the bottom of the upper platform on one side of the through groove. A feeding lifting push rod is vertically fixed on the cylinder body of the rodless cylinder. A mounting frame is fixed at the lower end of the piston rod of the feeding lifting push rod. A feeding suction cup that corresponds to the upper panel of the three-dimensional cardboard box and is connected to the air pump through a hose is fixed on the mounting frame.

[0014] A photoelectric sensor is fixedly installed on the platform below, located in front of the clamping push rod, and a conveyor is horizontally arranged on the front of the platform below, located in front of the photoelectric sensor.

[0016] Preferably, the opposite ends of the limiting guardrails corresponding to the large slope platform and the small slope platform are in contact with each other, and the lower end of the limiting guardrail corresponding to the large slope platform is in contact with the upper surface of the upper platform.

[0017] Preferably, the positioning card is L-shaped, and the curved part of the positioning card is engaged at the edge of the bottom of the flat cardboard box.

[0018] Preferably, there are four descending and unfolding suction cups, which are respectively located on the lower front panel of the flat cardboard box near the four corners.

[0019] Preferably, both the fixed guide plate and the movable guide plate include a vertical lower half and an inclined guide upper half.

[0020] Preferably, the support block is an elastic silicone pad.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention, by setting up an opening and locking bottom assembly, allows a flat cardboard box to automatically unfold into a three-dimensional box when it is pulled downwards by a descending unfolding suction cup and supported by the guide slope of a movable guide clamp. After being clamped by a clamping push rod, the lower support push rod, the side support push rod, and the upper support push rod work in sequence to close and lock the bottom flap, side flap, and locking bottom cover of the three-dimensional cardboard box, thus completing the self-locking bottom. This organically combines the opening and locking bottom assemblies, not only reducing the volume but also reducing the transfer time of the three-dimensional cardboard box between the two processes, improving efficiency and facilitating efficient packaging production. It solves the problems of increased floor space and reduced efficiency associated with using two sets of equipment for unfolding and locking pharmaceutical packaging boxes.

[0048] Working principle:

[0049] The flat cardboard boxes are manually placed on the large and small inclined platforms of the feeding assembly. The boxes are periodically pushed and adjusted to move downwards onto the positioning clips. The front and side panels of the flat cardboard boxes are parallelogram-shaped. The descending unfolding push rod and descending unfolding suction cup pull the flat cardboard boxes downwards. They are automatically unfolded into three-dimensional cardboard boxes by the guide slope of the movable guide clamp. The clamping push rod supports the movable guide clamp so that it clamps the three-dimensional cardboard boxes with the fixed guide clamp. The lower support push rod, side support push rod and upper support push rod work in sequence to close and lock the bottom flap, side flap and bottom locking cover of the three-dimensional cardboard boxes to complete the self-locking bottom. The unloading lifting push rod drives the unloading suction cup to pick up the three-dimensional cardboard boxes. The rodless cylinder moves the boxes forward to the conveyor to complete the unloading. Each time the photoelectric sensor recognizes the three-dimensional cardboard boxes, one opening, self-locking bottom and unloading cycle is completed.
