Description

Technical Field

[0001] This utility model relates to the technical field of packaging box manufacturing equipment, and in particular to a double suction bottom box opening machine. Background Technology

[0002] Before being formed, a typical cardboard box is a piece of paper with a certain number of creases. This includes a type of box where the top, bottom, and side panels are pre-assembled. Therefore, when folding the bottom, simply pull apart the top and bottom panels; folding can then be done from the top or bottom. Especially for sealing the bottom box, the inner tongue usually needs to be inserted into the box handles to prevent the bottom from opening. (See reference...) Figure 4 .

[0003] Existing cardboard box folding machines generally fold the cardboard box gradually during the pressing process by pressing down on it and relying on pre-set sheet metal. Therefore, this method of folding is generally suitable for cardboard boxes with top and bottom lids, but not for semi-finished cardboard boxes.

[0004] The overall length of the semi-finished cardboard box usually varies depending on the production batch. If the above-mentioned sheet metal folding method is used, it is easy to manually adjust the sheet metal position or select the sheet metal length, so further improvement is needed.

The lower suction and conveying device is installed below the storage mechanism, the upper box opening device, and the sealing component for conveying the carton. The upper box opening device is mounted above the lower suction and conveying device and works with it to open the carton. The upper box opening device includes a horizontal linear module, and the output end of the horizontal linear module is equipped with a suction pressure ear assembly that can move in the vertical direction.

A middle sealing cylinder is installed on the middle adjustment seat. The middle sealing cylinder is connected to the base plate in an adjustable manner through the middle adjustment seat. The lower box ear top block is fixedly provided at the end of the piston rod of the middle sealing cylinder. The lower box ear top block is mounted above the inner tongue bending top plate through the middle adjustment seat.

Subsequently, a sealing component sequentially folds and seals the bottom ears of the unfolded box. The sealing component's lifting angle is adjustable, and it uses two cylinder suction heads. The upper cylinder is paired with a horizontal linear module whose lateral movement distance is adjustable, thus adapting to cardboard boxes of different lengths and widths. This replaces manual box opening and sealing, improving packaging box production efficiency. The sequential control of the sealing component prevents interference and damage to the box ears during folding, increasing the yield rate of finished packaging boxes. Attached Figure Description

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0029] like Figure 1-3 As shown, this embodiment provides a double suction bottom box opening machine, including a storage mechanism 3, a lower suction conveying device, an upper box opening device, and a sealing component; the lower suction conveying device is installed below the storage mechanism 3, the upper box opening device, and the sealing component for conveying the carton; the upper box opening device is mounted above the lower suction conveying device and cooperates with the lower suction conveying device to open the carton. The upper box opening device includes a horizontal linear module 15, and the output end of the horizontal linear module 15 is equipped with a suction pressure ear assembly that can move in the vertical direction. The sealing component is located at one end of the lower suction conveying device.

[0030] During use, the lower suction and conveying device can pick up the paper from the storage mechanism 3 and move it to the lower part of the upper opening device. Then, the lower suction and conveying device can move down to pick up the paper from one side and pull it up to form a preliminary shape. This process can support the paper, and then the sealing component begins to seal the bottom of the pre-formed paper.

[0031] In this embodiment, the suction ear assembly includes a lifting drive 14, which is fixedly connected to the output end of a horizontal linear module 15, thus enabling the lifting drive 14 to move laterally. A lifting platform 10 is fixedly mounted on the output end of the lifting drive 14. Preferably, the lifting drive 14 uses a vertically positioned linear module, allowing it to control the vertical movement of the lifting platform 10. A suction head 11 is fixedly mounted at the bottom of the lifting platform 10. After descending to its designated position, the suction head 11 can pick up one side of the paper. As the lifting drive 14 controls the lifting platform 10 to move upward, it pulls up the suctioned paper for initial shaping. A flipping component 12 for folding the box ear is hinged to one side of the bottom of the lifting platform 10. When the lifting platform 10 moves downward, the flipping component 12 also descends to its designated position. A push-pull cylinder 13 is also fixedly mounted on one side of the lifting platform 10, extending downward and rotatably connected to the flipping component 12. Then, the push-pull cylinder 13 will push downwards, causing the flipping component 12 to also flip downwards. The downward flipping of the flipping component 12 can cause the upper ear of the cardboard box to bend downwards, waiting for the ear in other positions to be inserted and sealed. As can be seen from the above, the lifting platform 10 can move in both the horizontal and vertical directions through the horizontal linear module 15 and the lifting drive component 14.

[0032] In this embodiment, the lower adsorption and conveying device includes a longitudinal moving module and a lifting cylinder 8. The lifting cylinder 8 is fixedly connected to the output end of the longitudinal moving module. The longitudinal moving module can control the lifting cylinder 8 to move back and forth between the upper opening device, the packaging component, and the storage component. An adsorption fixture 9 is fixedly provided at the end of the piston rod of the lifting cylinder 8. The lifting cylinder 8 can control the adsorption fixture 9 to move upward to adsorb the paper placed in the storage component. Then, the lifting air hole controls the adsorption fixture 9, which has gripped the paper, to move downward. Under the control of the longitudinal moving module, the adsorption fixture 9, which has gripped the paper, moves to a position below the upper opening device, and then performs the above-mentioned opening action and the folding action of the upper box ear.

[0033] In this embodiment, a substrate 1 is also included. The packaging assembly is mounted on the substrate 1. The packaging assembly includes an inner tongue bending top plate 20 and multiple packaging cylinders. The inner tongue bending top plate 20 is movably connected to the substrate 1 through the packaging cylinders. The inner tongue bending top plate 20 is used to initially bend the inner tongue, so that it is easier to insert the lower ear into the upper ear when folding and packaging, and it can improve the reliability after packaging at the bottom of the box.

[0034] In this embodiment, a lower ear top block 21 is also provided above the inner tongue bending top plate 20. The inner tongue bending top plate 20 is a flat plate arranged parallel to the substrate 1. The inner tongue bending top plate 20 can be translated by the control of the sealing cylinder to perform preliminary bending on the end of the inner tongue. The substrate 1 is also fixedly provided with a middle adjustment seat 22, on which a middle sealing cylinder 23 is mounted. The middle sealing cylinder 23 is adjustablely connected to the substrate 1 through the middle adjustment seat 22. The lower ear top block 21 is fixedly provided at the end of the piston rod of the middle sealing cylinder 23. The lower ear top block 21 is supported above the inner tongue bending top plate 20 through the middle adjustment seat 22. The lower ear top block 21 can move forward to seal the lower ear inward. The lower ear top block 21 acts on the lower ear, causing the inner tongue, which is integral at one end of the lower ear, to be further inserted inward, specifically, to be inserted into the inner wall of the upper ear.

[0035] In this embodiment, a first encapsulation cylinder 16 extending obliquely upward is also installed at the bottom of the substrate 1. The piston rod of the first encapsulation cylinder 16 is fixedly provided with an encapsulation bending piece 17. The first encapsulation cylinder 16 controls the encapsulation bending piece to move in the oblique direction. Because the first encapsulation cylinder 16 is arranged obliquely, the piston rod of the first encapsulation cylinder 16 moves obliquely. The encapsulation bending piece 17 is fixedly provided at the top end of the piston rod, that is, the encapsulation bending piece 17 also moves obliquely. Therefore, when the encapsulation bending piece 17 moves obliquely upward, it can cause the lower ear to initially fold upward and wait for the lower ear top block 21 to move forward, so that the inner tongue at the end of the lower ear can be further inserted into the upper ear.

[0036] In this embodiment, a pair of side sealing cylinders 18 are symmetrically arranged on both sides of the tongue bending top plate. The piston rod end of the side sealing cylinder 18 is fixedly provided with a side box ear top block 19. Each pair of side sealing cylinders 18 is equipped with a side adjustment component. The side sealing cylinders 18 are movably and adjustablely connected to the substrate 1 through the side adjustment component. The side sealing cylinders 18 are all arranged at an angle, which can bend the side box ears respectively. Because during the opening action, that is, when the side box surface is pulled up, the side box ears on both sides are vertically pulled up and perpendicular to the substrate 1. At this time, the movement of the side box ear top block 19 will cause the side box ears on both sides to bend.

[0037] To further elaborate, the side adjustment assembly includes a relay plate, a slide rail, a screw, an adjusting sleeve, and a pair of bearing seats; the pair of bearing seats are fixedly mounted on the base plate 1, the bottom of the relay plate is equipped with a slide rail, and the relay plate is movably connected to the base plate 1 through the slide rail; both ends of the screw are rotatably connected to the bearing seats, the adjusting sleeve is threadedly connected to the screw, the adjusting sleeve is fixedly connected to the relay plate, and the side sealing cylinder 18 is fixedly mounted on the relay plate.

[0038] This invention uses dual cylinders to suction and tighten the upper and lower surfaces of the box, maintaining the stability of the box during the sealing process at the bottom. This means that the positional stability of each ear and inner tongue is higher, preventing misalignment or movement during sealing and ensuring the reliability of the sealed product. After adjusting the positions of each sealing cylinder, the sealing action can be performed. The specific sealing action is as follows: First, the flipping component 12 flips the upper box ear downwards. Then, the side box ear top blocks 19 on both sides move forward and fold the side box ears inwards. At the same time, the inner tongue bending top plate 20 moves forward to pre-bend the inner tongue at one end of the lower box page. Then, the sealing bending piece 17 moves diagonally upwards to control the lower box page to fold upwards. Then, the lower box ear top block 21 moves forward to control the lower box ear to move forward, and the inner tongue will be inserted into the upper box ear. The sealing is then completed. Afterwards, the lower suction and conveying device cancels the suction and resets. The suction head 11 on the lifting platform 10 moves the formed and sealed cardboard box to one side through the horizontal straight module 15 and then resets. When the next sealed cardboard box moves, it is similarly moved to one side through the horizontal straight module 15, which will continuously push out the previous cardboard box to achieve the effect of material discharge and feeding.

[0039] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
