Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, in particular to an inner-grid card inserting machine with a back-side adsorption function. Background Art

[0002] A card inserter is a paper processing device primarily used to insert partitions or liners into cartons or other packaging boxes to protect the packaged items and prevent damage during transportation and storage. However, conventional methods typically use manual labor to bond the inner and outer compartments of packaging boxes, resulting in poor efficiency and limited bonding precision, which can easily lead to misalignment and a large number of defective products.

[0003] Although some processing equipment can automatically process the products, the conveying mechanism of the equipment cannot correct the deviation of the outer box, which makes the relative position of the inner grid and the outer box inaccurate, and the bonding between the outer box and the inner card does not meet the process requirements, and cannot meet the requirements of high-precision, efficient and automated production of modern packaging boxes with inner grids.

DETAILED DESCRIPTION

[0014] The embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to illustrate the present invention and are not intended to limit the present invention.

[0015] An embodiment of the present invention provides an inner-grid card insertion machine, comprising 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. An outer box conveying mechanism 40 is provided on the base 20. The inner card conveying mechanism 30 and the outer box conveying mechanism 40 have the same feeding direction. The frame 10 is also provided with a suction platform 11, which is connected to both 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 is angled relative to the suction platform 11. The suction platform 11 is provided with a glue spraying and bonding device, which is located at the intersection 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 simultaneously reach the gluing device, where the gluing device sprays glue on the outer box to bond the inner card to the inner box. The glue spraying and bonding device of the embodiment of the present invention can be selected from existing mature products, and its specific structure is not limited.

[0016] The outer box conveying mechanism 40 includes an outer box suction device, which has a plurality of suction conveyor belts 41 and an air chamber plate and a bellows 44 arranged below the suction conveyor belt 41; the bellows 44 is installed below the air chamber plate. Optionally, the air chamber plate is provided with at least two rows of air holes and evenly distributed grooves, and the suction conveyor belt 41 is provided with evenly arranged adjustment holes and evenly distributed suction holes. In the embodiment of the present invention, due to the use of a movable air chamber plate, at least two rows of bellows 44 are provided in the front and rear under the air chamber plate, and the air hole switch assembly and evenly distributed grooves are provided on the air chamber plate, so that the suction distribution on the entire air chamber plate is even, and the number of air holes to be opened and closed can be determined according to the specifications of the outer box. The opening and closing operation of the air hole suction is performed by a solenoid valve to achieve flexible adjustment of the suction area, thereby saving wind power and ensuring effective concentration of air volume, and achieving fast and stable transportation.

[0017] A pulling gauge correction device is provided on both sides of the suction conveyor belt 41. The pulling gauge correction device includes a correction baffle 42 and multiple clamping bearings 43. The clamping bearings 43 are tilted and located below the suction conveyor belt 41 to achieve correction of the outer box when it is pulled by horizontal friction.

[0018] When the outer box is traveling on the suction conveyor belt 41, it is easy to deviate from the conveyor belt due to the high-speed movement of the outer box. In the embodiment of the present invention, the outer box is driven to move outward by cooperating with the gauge correction bearing device set on the suction conveyor belt 41, and finally fits with the correction baffle 42 on the gauge correction device to correct the position of the deviated outer box. Since the gauge correction device may deviate on the conveyor belt during the high-speed transmission of the outer box, the fixing frame below the conveyor belt can be locked by a locking member to enhance the stability of the conveyor belt operation. Specifically, the upper locking plate and the lower locking plate of the locking member can be locked together, and the position of the locking member on the slide can be controlled to achieve up and down movement. The positions of the upper and lower locking plates are adjusted to lock the offset gauge correction device, enhance the stability of the conveyor belt operation, and prevent the conveyor belt from shaking and affecting the correction effect of the outer box. The pressing device can be realized by any pressing device in the prior art in combination with hot melt adhesive.

[0019] 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 in the front of the inner card feeding direction, and the second conveyor belt 33 is located in the rear section of the inner card feeding direction. The inner card baffle 31 is arranged on both sides of the first conveyor belt 32; there is a paper feeding gap 34 at the connection between the first conveyor belt 32 and the second conveyor belt 33. 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 transported to the suction platform 11.

[0020] The base 20 includes two support plates arranged in parallel in the vertical direction, each support plate is formed by splicing a first baffle 21 and a second baffle 22; a plurality of cross beams 23 are arranged between the two support plates, and a plurality of supporting feet 24 are also arranged at the bottom of the support plates; the outer box conveying mechanism 40 is arranged on the cross beams 23 and is located in the space formed by the two support plates.

[0021] The frame 10 includes a first gantry 12 disposed above two first baffles 21 and a second gantry 13 disposed above two second baffles 22 ; the inner card conveying mechanism 30 is fixedly connected to the first gantry 12 and the second gantry 13 .

[0022] The frame 10 is also provided with a positioning device, which is arranged at the intersection of the outer carton 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 carton photoelectric sensor 53, and a controller 54. The inner card photoelectric sensor 52 is used to sense the inner card position signal, and the outer carton photoelectric sensor 53 is used to sense the outer carton position signal. 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 carton position signal. Specifically, the controller 54 can compare the inner card position signal transmitted by the inner card photoelectric sensor 52 with the outer carton signal transmitted by the outer carton photoelectric sensor 53 to determine whether the inner card and outer carton positions correspond. If the inner card and outer carton positions do not correspond, the correction motor in the correction device is activated to drive the correction wheel to correct the position, thereby achieving automatic correction of the outer carton and inner card at the front end during high-speed conveyance, ensuring the accuracy of the alignment between the two and the quality of the finished product.

[0023] The internal card insertion machine provided in the embodiment of the present invention operates as follows: an inner card is conveyed to a paper feed table. Suction devices are located below the first conveyor belt 32 and above the second conveyor belt 33 of the paper feed table, operating in the same manner as the outer box suction device. A paper feed 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 conveyor mechanism 40 conveys the outer box via the suction conveyor belt 41 of the guide guide device. Finally, a positioning device aligns the inner card and outer box, ensuring that they are conveyed at the same speed to the adhesive bonding device, reaching the junction point simultaneously and completing the bonding process. The entire process is driven by a single motor, enhancing the synchronization and coordination between the inner card conveyor mechanism and the outer box conveyor mechanism 40, further improving the accuracy of the packaging box bonding process.
