Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to an internal card insertion machine that can be precisely positioned. Background Technology

[0002] A card inserter is a paper processing device mainly used to insert partitions or liners into cartons or other packaging boxes to protect packaged goods and prevent damage during transportation and storage. However, in the existing technology, the gluing of the inner compartments of the packaging box to the outer box is usually done manually, which is inefficient and lacks sufficient gluing precision, easily leading to misalignment and a large number of defective products.

[0003] Although some processing equipment can automate the process, the conveying mechanism of the equipment cannot correct the deviation of the outer box. This results in inaccurate relative positions between the inner compartments of the packaging box and the outer box, which in turn makes the bonding between the outer box and the inner card fail to meet the process requirements. Consequently, it cannot meet the requirements of high precision, high efficiency, and automated production of modern packaging boxes with inner compartments. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide an internal card insertion machine capable of high-precision and high-speed bonding.

[0005] This utility model provides a precise positioning inner card insertion machine, which includes a frame and a base. The frame is fixed above the base and is equipped with an inner card conveying mechanism. An outer box conveying mechanism is provided on the base. The inner card conveying mechanism and the outer box conveying mechanism have the same feeding direction. The inner card conveying mechanism includes a first conveyor belt and a second conveyor belt. The first conveyor belt is located at the front section of the inner card feeding direction, and the second conveyor belt is located at the rear section of the inner card feeding direction. The outer box conveying mechanism is equipped with a suction conveyor belt.

[0006] Optionally, the frame is also provided with a positioning device, which is located at the junction of the outer box conveying mechanism and the inner card conveying mechanism;

[0007] The positioning device includes an inner card correction wheel, an inner card photoelectric sensor, an outer box photoelectric sensor, and a controller. The inner card photoelectric sensor is used to sense the inner card position signal, the outer box photoelectric sensor is used to sense the outer box position signal, and the controller is used to control the operation of the inner card correction wheel according to the inner card position signal and the outer box position signal.

[0008] The frame is also equipped with a suction platform, which is connected to the outer box conveying mechanism and the inner card conveying mechanism. The inner card conveying mechanism is located on the suction platform and is at a certain angle relative to the suction platform. The suction platform is equipped with a glue spraying device, which is located at the junction of the inner card conveying mechanism and the outer box conveying mechanism. The inner card conveyed by the inner card conveying mechanism and the outer box conveyed by the outer box conveying mechanism arrive at the glue spraying device at the same time, so that the glue spraying device sprays glue onto the outer box to glue the inner card inside the outer box.

[0009] Optionally, the outer box conveying mechanism includes an outer box suction device, which has multiple suction conveyor belts and a wind chamber plate and a wind box disposed below the suction conveyor belts;

[0010] The suction conveyor belt is equipped with a guide rail correction device on both sides. The guide rail correction device includes a correction baffle and multiple clamping bearings. The clamping bearings are inclined to achieve correction when the outer box is pulled laterally by friction.

[0011] Optionally, the inner card conveying mechanism further includes inner card baffles, which are disposed on both sides of the first conveyor belt;

[0012] The first and second conveyor belts have a paper feeding gap at their junction. The inner card is located above the first conveyor belt and, after reaching the paper feeding gap via the first conveyor belt, is pressed by the second conveyor belt and continues to be conveyed to the suction platform.

[0013] Optionally, the base includes two support plates arranged parallel to each other in the vertical direction, each support plate being formed by splicing a first baffle and a second baffle; multiple crossbeams are provided between the two support plates, and multiple support feet are also provided at the bottom of the support plates; the outer box conveying mechanism is disposed on the crossbeams and located within the space formed by the two support plates.

[0014] The technical effect achieved by the precisely positioning internal card insertion pin of this utility model is:

[0015] 1. The inner card and outer box are fed by a suction conveyor belt throughout the process, supplemented by a guide rail, which ensures that the outer box is transported forward smoothly. This further ensures that the outer box and inner box reach the meeting point at the same time, which can more effectively complete the correction action, meet the needs of high-speed bonding, and expand the application range of the equipment.

[0016] 2. By using the same motor to drive both the outer box conveying mechanism and the card conveying mechanism, the synchronization of their movements is ensured, enabling high-speed paper feeding and bonding operations and effectively improving production efficiency. The installation of a photoelectric sensing positioning device ensures automatic front-end correction of the outer box and inner compartment during high-speed transport, guaranteeing bonding accuracy.

Detailed Implementation

[0027] The embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only for explaining the present invention and are not restrictive.

[0028] This utility model embodiment provides a precise positioning inner card insertion machine, which includes a frame 10 and a base 20. The frame 10 is fixed above the base 20 and is provided with an inner card conveying mechanism 30. The base 20 is provided with an outer box conveying mechanism 40, and the inner card conveying mechanism 30 and the outer box conveying mechanism 40 have the same feeding direction.

[0029] The frame 10 is also equipped with a suction platform 11, which is simultaneously connected to the outer box conveying mechanism 40 and the inner card conveying mechanism 30. The inner card conveying mechanism 30 is located on the suction platform 11 and forms a certain angle with respect to the suction platform 11. The suction platform 11 is equipped with a glue spraying device, located at the junction of the inner card conveying mechanism 30 and the outer box conveying mechanism 40. The inner card conveyed by the inner card conveying mechanism and the outer box conveyed by the outer box conveying mechanism arrive at the glue spraying device simultaneously, so that the glue spraying device sprays glue onto the outer box to glue the inner card inside the outer box. The frame 10 includes a first gantry frame 12 disposed above two first baffles 21 and a second gantry frame 13 disposed above two second baffles 22. The inner card conveying mechanism 30 is fixedly connected to the first gantry frame 12 and the second gantry frame 13.

[0030] The outer box conveying mechanism 40 includes an outer box suction device, which has multiple suction conveyor belts 41 and a wind chamber plate and air boxes 44 disposed below the suction conveyor belts 41; the air boxes 44 are installed below the wind chamber plate. Optionally, the wind chamber plate has at least two rows of air holes and evenly distributed grooves, and the suction conveyor belts 41 have evenly arranged adjustment holes and evenly distributed suction holes. This embodiment of the invention uses a movable wind chamber plate, with at least two rows of air boxes 44 arranged below the wind chamber plate, air hole switching components on the wind chamber plate, and evenly distributed grooves, ensuring uniform air suction distribution across the entire wind chamber plate. Furthermore, the number of air holes that can be opened or closed can be determined according to the specifications of the outer box. The opening and closing of the air holes is controlled by a solenoid valve to flexibly adjust the suction area, thereby saving airflow and ensuring effective concentration of air volume, achieving fast and stable conveying.

[0031] The suction conveyor belt 41 is provided with a guide correction device on both sides. The guide correction device includes a correction baffle 42 and multiple clamping bearings 43. The clamping bearings 43 are inclined and located below the suction conveyor belt 41 to realize the correction of the outer box when it is pulled laterally by friction.

[0032] As the outer box travels on the suction conveyor belt 41, its high speed can easily cause it to deviate from the conveyor belt. In this embodiment, a guide bearing device mounted on the suction conveyor belt 41 moves the outer box outward, eventually engaging with the correction baffle 42 on the guide bearing device to correct the deviated position. Since the guide bearing device may deviate from the conveyor belt during high-speed transport, a locking mechanism can be used to lock the lower frame of the conveyor belt, enhancing its stability. Specifically, the upper and lower locking plates of the locking mechanism work together to lock the guide bearing. By controlling the position of the locking mechanism on the slide groove, the upper and lower locking plates are adjusted to lock the deviated guide bearing device, enhancing the stability of the conveyor belt and preventing belt vibration from affecting the outer box correction effect. The pressing device can be implemented using any existing pressing device combined with hot melt adhesive.

[0033] The inner card conveying mechanism 30 includes an inner card baffle 31, a first conveyor belt 32, and a second conveyor belt 33. The first conveyor belt 32 is located at the front section of the inner card feeding direction, and the second conveyor belt 33 is located at the rear section of the inner card feeding direction. The inner card baffle 31 is disposed on both sides of the first conveyor belt 32. The connection between the first conveyor belt 32 and the second conveyor belt 33 has a paper feeding gap 34. The inner card is located above the first conveyor belt 32, and after reaching the paper feeding gap 34 via the first conveyor belt 32, it is pressed by the second conveyor belt 33 and continues to be conveyed to the suction platform 11.

[0034] The base 20 includes two support plates arranged parallel to each other in the vertical direction. Each support plate is formed by splicing a first baffle 21 and a second baffle 22. Multiple crossbeams 23 are arranged between the two support plates, and multiple support feet 24 are also arranged at the bottom of the support plates. The outer box conveying mechanism 40 is arranged on the crossbeams 23 and is located in the space formed by the two support plates.

[0035] A positioning device is also provided on the frame 10, located at the junction of the outer box conveying mechanism 40 and the inner card conveying mechanism 30. The positioning device includes an inner card correction wheel 51, an inner card photoelectric sensor 52, an outer box photoelectric sensor 53, and a controller 54. The inner card photoelectric sensor 52 is used to sense the inner card position signal, the outer box photoelectric sensor 53 is used to sense the outer box position signal, and the controller 54 is used to control the operation of the inner card correction wheel 51 based on the inner card position signal and the outer box position signal. Specifically, the controller 54 can compare the inner card position signal transmitted by the inner card photoelectric sensor 52 and the outer box signal transmitted by the outer box photoelectric sensor 53 to see if the inner card and outer box positions correspond. When the inner card and outer box positions do not correspond, the correction motor in the correction device is activated to drive the correction wheel to correct the alignment, thereby realizing the automatic correction function of the outer box and inner card at the front end during high-speed conveying, ensuring the accuracy of their alignment and the quality of the finished product.

[0036] The working process of the inner card inserter provided in this embodiment of the utility model is as follows: the inner card is conveyed to the paper feeding table. Suction devices are also provided below the first conveyor belt 32 and above the second conveyor belt 33 on the paper feeding table, and their working principle is the same as that of the outer box suction device. A paper feeding gap 34 is formed between the outer box suction device and the second conveyor belt 33. The inner card is conveyed along the second conveyor belt 33, while the outer box conveying mechanism 40 conveys the outer box via the suction conveyor belt 41 of the guide correction device. Finally, the positioning device calculates and corrects the inner card and the outer box to achieve the same speed as the inner card and the outer box, which are then conveyed to the glue spraying and bonding device, allowing the inner card and the outer box to reach the confluence point simultaneously and complete the bonding. The entire process is driven by a single motor, which improves the synchronization and coordination of the inner card conveying mechanism and the outer box conveying mechanism 40, and is more conducive to improving the accuracy of packaging box bonding.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
