Description

Technical Field

[0001] This utility model relates to an automated production equipment for a packaging line, specifically a high-speed cardboard forming device with glue dispensing function. Background Technology

[0002] Packaging boxes are indispensable packaging products in daily life and industrial production. Due to their environmental friendliness, lightweight nature, and ease of processing, they are widely used in the packaging of various products, from food and pharmaceuticals to electronic devices. Cardboard boxes are not only containers for protecting and storing products, but also tools for conveying product information and promoting sales.

[0003] The basic functions of cardboard boxes can be summarized in three points: First, they protect products, ensuring they are not damaged by various external factors during production, transportation, storage, and sales; second, they facilitate storage and transportation, as the rational structure of cardboard boxes effectively utilizes space and facilitates transportation and stacking for storage; and third, they promote sales, as a well-designed cardboard box can attract consumers' attention, enhance the display effect of goods, and stimulate consumers' desire to buy. Only carefully designed and manufactured cardboard boxes can make a product stand out among numerous commodities.

[0004] However, most cardboard boxes on the market are foldable after production, mainly to save on transportation and storage costs. When in use, these foldable boxes need to be unfolded and shaped into a three-dimensional form. Currently, many companies still use traditional manual methods to complete this operation, which is not only inefficient and costly, but also prone to errors, leading to deformation or damage to the boxes.

[0005] Traditional manual box opening and shaping methods have many shortcomings. First, the large amount of manpower required means high labor costs, especially in mass production. Second, the instability of manual operation can lead to inconsistent box quality, which can have serious consequences in some fields with strict packaging requirements, such as pharmaceuticals and cosmetics. Furthermore, with increasingly stringent environmental regulations, manual box opening and shaping can also lead to material waste, which is detrimental to environmental protection.

[0006] For the reasons mentioned above, there is an urgent need in the market for a new type of paper box opening and forming method and equipment to improve production efficiency, reduce labor costs, ensure stable paper box quality, and meet increasingly stringent environmental protection requirements.

[0012] Corresponding to the folding area, a presser is installed above it by sliding up and down via a guide post. Driven by the folding power mechanism, the presser moves up and down along the guide post, driving the presser into the folding area to fold the cardboard to be formed into a packaging box.

[0013] The pushing device includes a pushing slider that is slidably installed at the bottom of the guide rail groove, and the pushing slider is driven to move by a pushing power mechanism.

[0014] The aforementioned feeding power mechanism includes a feeding pulley driven by a feeding servo motor, which drives the feeding slider to move via a feeding timing belt.

[0015] The front end of the pusher slider is equipped with a pusher baffle, which drives the cardboard to be formed to move.

[0016] The presser includes an upper positioning plate and a lower positioning plate, which are spaced apart and connected by a column.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. A high-speed cardboard forming device with glue dispensing function is characterized in that it includes a feeding mechanism 1, a glue dispensing mechanism 2, and a stamping forming mechanism 3.

[0029] The feeding mechanism 1 includes a guide rail groove 11, and a pushing device is provided at the tail of the guide rail groove 11. After the cardboard 7 to be formed is placed in the guide rail groove 11, it is pushed by the pushing device to move in the discharge direction.

[0030] The dispensing mechanism 2 includes a dispensing gun that spans across the upper end of the feeding mechanism 1. The dispensing gun expels hot melt adhesive and drips it onto the cardboard 7 to be formed below.

[0031] The stamping forming mechanism 3 includes: a base plate 31, a positioning frame 32 installed on the base plate 31, and rollers 33 rolled on the four side plates of the positioning frame 32, with the four rollers 33 forming a folding area 35.

[0032] Corresponding to the folding area 35, a presser 4 is installed above it by sliding up and down through a guide post 36. Driven by the folding power mechanism, the presser 4 moves up and down along the guide post 36, driving the presser 4 into the folding area 35 to fold the cardboard 7 to be formed into a packaging box 71.

[0033] The pushing device includes a pushing slider 37 that is slidably installed at the bottom of the guide rail groove 11. The pushing slider 37 is driven to move by a pushing power mechanism.

[0034] The aforementioned feeding power mechanism includes a feeding pulley 39 driven by a feeding servo motor 38, which drives the feeding slider 37 to move via a feeding timing belt.

[0035] The front end of the pusher slider 37 is equipped with a pusher baffle 392, which drives the cardboard 7 to be formed to move.

[0036] The presser 4 includes an upper positioning plate 41 and a lower positioning plate 42. The upper and lower positioning plates are distributed at intervals and connected by a column 43. The lower positioning plate 42 has a hollowed-out center to form a cavity 44. An inner pressure plate 45 is installed in the cavity 44. A folding cylinder 46 on the upper positioning plate 41 is connected to the inner pressure plate 45. The folding cylinder 46 drives the inner pressure plate 45 to move up and down in the cavity 44.

[0037] The inner pressure plate 45 is equipped with a sliding column 47 on its top, and the sliding column 47 is slidably inserted into the sleeve 48 located on the upper positioning plate 41.

[0038] The folding power mechanism includes a drive plate 5 slidably mounted on the guide post 36, a presser 4 fixed below the drive plate 5, a folding power motor 51 fixed on the frame 6 and a main pulley 52 driven by it, the main pulley 52 being connected to a driven pulley 54 fixed on the frame 6 via a synchronous belt 53, the synchronous belt 53 being connected to the drive plate 5 via a pressure bar 55, and the presser 4 being driven by the synchronous belt 53 during operation.

[0039] There are two main pulleys 52, which are symmetrically installed on both ends of the rotating shaft 56 on the frame 6. Correspondingly, there are two driven pulleys 54 on both sides of the frame 6, and the synchronous belt 53 is located on both sides of the drive plate 5.

[0040] The rotating shaft 56 is driven to rotate by the folding motor 51.

[0041] Working principle: The design of this high-speed cardboard forming device completely solves the problems of low efficiency and instability of traditional manual box opening. Its detailed working principle is as follows:

[0042] 1. Feeding Process: Initially, the cardboard 7 to be formed is placed into the guide rail groove 11 by automated equipment or manually. Subsequently, the pusher pulley 39, driven by the pusher servo motor 38, drives the pusher slider 37 to begin its movement via the pusher timing belt 53. The front end of this slider is equipped with a pusher baffle 392, which ensures that the cardboard moves smoothly and orderly along the guide rail groove, and then enters the next workstation. This mechanized conveying process significantly improves the feeding speed and accuracy.

[0043] 2. Glue Dispensing Process: As the cardboard passes through glue dispensing mechanism 2, the glue gun located above the feeding mechanism expels an appropriate amount of hot melt glue according to a preset program and position, accurately dripping it onto the cardboard to be formed. This automated and precise control not only reduces glue waste but also ensures consistent glue dispensing quality and position for each carton. The hot melt glue dripping point is generally set at the junction of the cardboard side panels, allowing for side panel connection using the overlapping areas during carton forming.

[0044] 3. Forming Process: The cardboard then moves to the stamping forming mechanism 3. Here, the base plate 31 and the positioning frame 32 cooperate to ensure that the cardboard is accurately positioned. At this time, the rotating shaft 56 driven by the folding power motor 51 in the folding power mechanism starts. The main pulley 52 and the driven pulley 54 connected by the timing belt 53 move synchronously, driving the drive plate 5 and the presser 4 to move up and down. When the presser descends to the appropriate position, the lower positioning plate restricts the position of the cardboard. Then, the inner pressure plate 45 moves downward, pressing the bottom of the cardboard into the folding area 35. With the cooperation of the upper positioning plate 41, the lower positioning plate 42, and the inner pressure plate 45, the cardboard is completely folded into a box shape.

[0045] In summary, the entire automated cardboard forming process is a series of precise, efficient, and stable mechanical actions. From cardboard feeding and gluing to folding and forming, each step is meticulously designed to ensure the high quality of the final cardboard box. This automated production method significantly improves production efficiency, reduces labor and material costs, and makes the entire production process more economical, environmentally friendly, and stable.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this invention.
