Description

Technical Field

[0001] The present invention relates to the technical field of paper box forming equipment, and in particular to a compartmentalized paper box forming device and a multi-compartment paper box forming machine. Background Art

[0002] Paper boxes are widely used for packaging of various products, including food, medicine, and electronics. Paper boxes on the market generally have a single cavity, so they can only hold items of the same type. As people's needs change, more and more people want to divide the interior of a paper box into multiple compartments, so that different types of items can be placed separately in a single box. The processing of multi-compartment paper boxes is usually done manually, by gluing dividing paper inside the box to divide the boxes. This not only requires high labor costs but also has low production efficiency.

[0003] For example, a multi-grid paper box automatic forming machine disclosed in a Chinese utility model patent (CN 209832767 U) includes a first paper storage rack arranged on a frame, a first paper feeding assembly is provided near the first paper storage rack, a paper box forming assembly is provided on one side of the first paper feeding assembly, a strip connecting assembly is provided on one side of the paper box forming assembly, a strip forming assembly is provided near the strip connecting assembly, the strip forming assembly includes a second paper storage rack, and a second paper feeding assembly and a movably arranged strip forming mold are provided between the second paper storage rack and the strip connecting assembly.

[0004] During operation, the paper feeder feeds the paper sheets stacked on the second paper storage rack into the insert forming mold. The upper mold descends and cooperates with the lower mold to form the inserts. The inserts are then transferred to the insert connecting assembly, where they are connected to the inner cavity of the formed paper box, thereby dividing the paper box into multiple compartments. However, the insert forming and insert connecting components of the insert forming assembly cannot be performed simultaneously, resulting in long waiting times in between, resulting in low work efficiency.

[0005] In order to improve work efficiency, the above patent further sets up two sets of strip forming components, which work alternately. However, such a setting not only makes the equipment larger and increases the occupied space area, but also greatly increases the cost. Summary of the Invention

[0022] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0023] As shown in the figure, a multi-grid carton forming machine includes a machine base 1, on which is provided a carton conveying device 100 capable of conveying carton along the X-axis direction, and a main box forming device 200, a grid carton forming device 300, and a finished product carton unloading device 400 arranged in sequence along the conveying direction of the carton conveying device 100.

[0024] The machine base 1 is provided with a mounting bracket 8, and the mounting bracket 8 includes a middle platen 82 and an upper platen 81. The middle platen 82 is mounted on the machine base 1 through a first column 83, and the upper platen 81 is mounted on the middle platen 82 through a second column. A hollow groove 821 is formed on the middle platen 82 for the upper mold mechanism 7 to move.

[0025] The paper box conveying device generally includes two groups of box body clamping mechanisms 14 and two groups of box cover clamping mechanisms 15. The two groups of box body clamping mechanisms 14 are arranged on the base 1 at intervals along the X-axis direction and slide with the base 1. The two groups of box body clamping mechanisms 14 are synchronously connected to the first conveying drive assembly and can slide synchronously along the X-axis direction. The two groups of box cover clamping mechanisms 15 are arranged on the middle plate 82 at intervals along the X-axis direction and slide with the middle plate 82. The two groups of box cover clamping mechanisms 15 are synchronously connected to the second conveying drive assembly and can slide synchronously along the X-axis direction. Among them, the first conveying drive assembly and the second conveying drive assembly both adopt a synchronous belt transmission method. Of course, in order to ensure the synchronization of the movement of the box body clamping mechanism and the box cover clamping mechanism, the first conveying drive assembly and the second conveying drive assembly are driven by the same motor and synchronous transmission is achieved through a synchronous belt.

[0026] During transportation, the box body clamping mechanism clamps the side of the carton body, and the box cover clamping mechanism clamps the side of the carton cover, thereby achieving reliable clamping of the carton, and then through sliding action along the X-axis direction, the carton is transported from the main box forming device 200 to the grid carton forming device 300, and the carton is transported from the grid carton forming device 300 to the finished carton unloading device 400. The two sets of box body clamping mechanisms 14 and the two sets of box cover clamping mechanisms 15 can achieve the synchronous transportation of the carton from the main box forming device 200 to the grid carton forming device 300 and the grid carton forming device 300 to the finished carton unloading device 400, thereby improving work efficiency.

[0027] The master box forming device 200 includes a master box paper feeding mechanism 9, a master box paper conveying mechanism 10, and a master box forming mechanism 11, which are sequentially arranged along the Y-axis direction. The master box paper feeding mechanism 9 includes a first paper storage rack for storing master box paper sheets, below which is disposed a master box paper suction cup assembly that can move up and down; the master box paper conveying mechanism 10 includes a first paper feeding rack for conveying master box paper sheets and a first paper feeding drive assembly that can drive the paper feeding rack to move along the Y-axis direction; the first paper feeding rack is formed with a master box paper positioning groove corresponding to the master box paper sheets; the master box forming mechanism 11 includes a master box forming lower mold and a main box forming upper mold; the main box forming lower mold is movably arranged on the machine base, and the main box forming upper mold is movably arranged on the middle plate 82.

[0028] When the main box is formed, the main box paper suction cup assembly rises and sucks the main box paper at the bottom of the first paper storage rack, and then the main box paper suction cup assembly descends, pulls out a main box paper piece downward and places it in the main box paper piece positioning slot of the first paper feeding rack, and then the first paper feeding drive assembly drives the paper feeding rack to move along the Y-axis direction to transport the main box paper piece to the main box forming mechanism, and then the main box forming lower mold and the main box forming upper mold are closed, and the main box is formed. At the same time, the first paper feeding drive assembly drives the first paper feeding rack to reset and move along the Y-axis direction to perform the next main box forming action.

[0029] The finished product carton unloading device 400 includes a conveyor belt 12 arranged along the Y-axis direction and a unloading mechanism 13 that pushes the finished product master box into the conveyor belt 12.

[0030] The compartment paper box forming device includes a compartment paper feeding mechanism 2 for feeding compartment paper sheets, a baffle forming lower mold 3 for forming the baffle, and a bonding lower mold 4 for bonding the baffle to the main box, which are sequentially arranged on the machine base 1 along the Y-axis direction.

[0031] Among them, the grid paper feeding mechanism 2 includes a second paper storage rack 21 for storing main box paper sheets, and a grid paper suction cup assembly 22 that can move up and down is provided under the second paper storage rack 21; the baffle forming lower mold 4 and the bonding lower mold 5 can be movably provided on the machine base.

[0032] The compartmented carton forming device 300 further includes a lower turntable 5 , an upper turntable 6 and an upper mold mechanism 7 .

[0033] The lower turntable 5 is rotatably mounted between the grid paper feeding mechanism 2 and the baffle forming lower die 3. Two centrally symmetrical grid paper positioning slots 51 are formed on the lower turntable 5, and the two grid paper positioning slots 51 correspond to the grid paper feeding mechanism 2 and the baffle forming lower die 3, respectively. The lower turntable 5 is rotatably mounted on one of the first uprights 83 and is connected to a first rotary drive assembly 52 that drives its rotation. The first rotary drive assembly 52 utilizes a motor-driven belt transmission structure. The lower turntable 5 uses the first upright 83 as its central rotation axis, effectively utilizing space and achieving a reasonable and compact layout.

[0034] The upper turntable 6 is rotatably mounted between the baffle forming lower mold 3 and the bonding lower mold 4. A "7"-shaped support 61 is mounted on the machine base 1. A rotating shaft 62 is rotatably mounted between the support 61 and the upper platen 81. The rotating shaft 62 is connected to a second rotating drive component 63 that drives it to rotate. The upper turntable 6 is sleeved outside the rotating shaft 62 and fixedly connected to the rotating shaft 62. The second rotating drive component 63 adopts a belt transmission structure driven by a motor.

[0035] The upper mold mechanism 7 is installed on the upper turntable 6. The upper mold mechanism 7 is provided with two groups and is symmetrically arranged along the center of the upper turntable 6. The two groups of upper mold mechanisms 7 correspond to the baffle molding lower mold 3 and the bonding lower mold 4 respectively. The upper mold mechanism 7 includes an upper mold 73, a guide shaft 74, and an elastic reset member 75. The upper end of the upper mold 73 is connected to a plurality of guide shafts 74, and the upper end and the upper turntable 6 are slidably matched through the guide shafts 74. The elastic reset member 75 is connected to the guide shaft 74 and can provide an elastic force for the guide shaft 74 to slide upward. There are four guide shafts 74, and the upper end of the guide shaft 74 is connected to the limit block 76. The elastic reset member 75 includes a plurality of springs. The springs are sleeved on the guide shaft 74, and the upper end of the spring is against the limit block 76, and the lower end is against the upper turntable 6.

[0036] The upper platen 81 is also equipped with a cylinder assembly 71 corresponding to the position of the baffle forming lower mold 3, and an oil cylinder assembly 72 corresponding to the position of the bonding lower mold 4. The baffle forming and baffle bonding are driven by the cylinder and the oil cylinder respectively. The cylinder action block is low in cost and can realize rapid molding of the baffle. The oil cylinder has a stronger locking force to ensure stable mold closing between the upper mold and the bonding lower mold, and ensure that the baffle and the main box can be bonded.

[0037] The forming of the compartmentalized paper box mainly includes two parts: baffle forming and baffle bonding.

[0038] When the baffle is formed, the grid paper suction cup assembly 22 first rises and sucks the grid paper at the bottom of the second paper storage rack 21. Then the grid paper suction cup assembly 22 descends, pulls out a grid paper and places it in the grid paper positioning groove 51 of the lower turntable 5. Then the first rotary drive assembly 52 drives the lower turntable 5 to rotate 180 degrees, transporting the grid paper to the top of the baffle forming lower mold 3. Then the cylinder assembly 71 is activated to press the corresponding upper mold mechanism downward. The upper mold 73 pushes the grid paper downward from the grid paper positioning groove. The upper mold 73 and the baffle forming lower mold 3 are closed to form the grid paper into a baffle. After the baffle is formed, the cylinder assembly 71 is reset. The upper mold 73 is also reset under the action of the elastic reset member 75. The formed baffle is left in the upper mold, so that the upper mold 73 can move with the formed baffle. Among them, the baffle is in an inverted V shape after being formed and can be supported in the molding groove at the bottom of the upper mold 73. Of course, an adsorption component can be further provided in the upper mold 73 for adsorbing the baffle to ensure that the upper mold 73 can carry and transfer the baffle.

[0039] When the baffle is bonded, the second rotary drive assembly 63 drives the upper turntable 6 to rotate 180°, transferring the upper mold mechanism 3 from above the baffle forming lower mold 3 to above the bonding upper mold 4, and the cylinder assembly 72 is actuated to press the upper mold mechanism downward, and the upper mold 73 is moved downward to close the bonding lower mold 4, so that the baffle in the upper mold 73 and the main box in the bonding lower mold 4 are bonded to each other to form a complete compartmented paper box.

[0040] The working process of the above-mentioned carton forming machine is as follows:

[0041] 1. Master box forming: the master box paper is formed into a master box through the steps of loading, conveying and forming in sequence;

[0042] 2. Master box conveying, the box body clamping mechanism and the box cover clamping mechanism clamp the side of the master box body and the side of the main box cover respectively, and transfer the master box from the master box forming mechanism to the bonding lower mold;

[0043] 3. The grid paper box is formed. The grid paper pieces are sequentially loaded, conveyed, and formed to form a baffle structure. The baffle is then transferred to the bonding station through the upper mold mechanism and cooperated with the bonding lower mold to bond the baffle to the main box to form a finished grid paper box.

[0044] 4. The compartmented carton is conveyed. The box body clamping mechanism and the box cover clamping mechanism clamp the side of the main box body and the side of the main box cover respectively, and transfer the finished compartmented carton from the bonding lower mold to the unloading station;

[0045] 5. The finished product compartment carton is unloaded, and the unloading mechanism is activated to push the finished product compartment carton to the conveyor belt, and then sent out by the conveyor belt.

[0046] By adopting the above scheme, the compartmented paper box forming device 300 adopts a two-turntable structure of an upper turntable and a lower turntable, so that during the compartmented paper box forming process, the compartmented paper suction cup assembly 22, the cylinder assembly 71, and the oil cylinder assembly 72 can move synchronously, thereby realizing the synchronous action of compartmented paper sheet loading, baffle forming, and baffle bonding, reducing the intermediate waiting time and greatly improving work efficiency. At the same time, compared with the structure of setting two groups of strip forming assemblies in the prior art, the overall volume is smaller, saving space and reducing production costs.
