Description

Technical Field

[0001] This utility model specifically relates to the field of cardboard folding technology, and more specifically to a fully automatic cardboard folding device. Background Technology

[0002] With the booming commodity economy, the output of various products has increased significantly, leading to a growing demand for packaging. Cardboard folding boxes, due to their wide availability of raw materials, ease of processing, low cost, and the ability to achieve exquisite designs through printing, have become one of the mainstream choices in the packaging industry. Currently, traditional cardboard box folding relies on manual labor, which is inefficient and can lead to fatigue and affect folding quality over time. While automated folding devices have emerged to meet increasingly higher quality requirements, they often produce unclear creases on the cardboard, resulting in uneven folds and misalignment between adjacent or opposite sides, further impacting quality. Furthermore, traditional equipment cannot precisely control the folding process during transport, compromising efficiency. Although some devices incorporate crease-setting mechanisms, the pressure applied during transport can cause the cardboard ends to curl upwards, hindering accurate and precise crease application at the folding points. A search revealed Chinese Patent Publication No. CN201920267021.8, which discloses an automatic box folding machine. The machine includes: a feeding mechanism, a material feeding mechanism, a material conveying mechanism, and a pressing mechanism; a mold support mechanism for closing the side panels of the pressed cardboard to form a semi-finished box; a side folding mechanism for folding the upright side panels of the cardboard inward to the inner wall of the semi-finished box, forming an open box; and a semi-finished product transport mechanism for conveying the semi-finished box from the mold support mechanism to the side folding mechanism and from the side folding mechanism to the box storage area. The device in the aforementioned patent directly presses down on the cardboard when folding it. This may cause the cardboard to bend on one side due to unclear creases, resulting in different dimensions between the different sides of the carton and affecting the overall quality of the folded cardboard box. Furthermore, if the pressing mechanism in the aforementioned patent malfunctions, it cannot effectively guarantee the folding operation. Utility Model Content

[0003] The purpose of this invention is to provide a fully automatic cardboard folding device. In this device, cardboard is fed one by one through a feeding component, which effectively avoids interference between adjacent cardboards during transport. The transmission component effectively transports the cardboard. During transport, the cooperation between the conveyor belt on the transmission frame and the hanging wheels at the bottom of the hanging wheel frame effectively ensures the flatness of the cardboard during transport. A crease component set between two transmission frames can effectively crease the cardboard at the bending position through the crease roller, thereby effectively ensuring the quality of the folding in subsequent folding. The crease roller cooperates with the belt through a pulley, and one of the pulleys cooperates with the rotating shaft at one end of the conveyor belt in the transmission component through a drive shaft, so that the crease roller and the conveyor belt rotate synchronously, thereby effectively ensuring the crease quality of the crease roller on the cardboard and ensuring the quality of the subsequent folding of the cardboard; thus solving the problems of the aforementioned background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An automatic cardboard folding device includes a base; a feeding component is mounted on the base; the discharge end of the feeding component is mounted with a conveying component; the conveying component includes two symmetrical conveyor frames; a conveyor belt is mounted inside each conveyor frame; one end of each conveyor belt is mounted with a rotating shaft; the conveyor frames are fixedly mounted to a protective frame via a support plate; the rotating shaft at one end of the protective frame drives the conveyor belts inside the two conveyor frames to rotate, effectively conveying the cardboard to the bottom of the folding component, thereby effectively ensuring the quality of the cardboard folding process. The top of the conveyor frame near the feeding component is equipped with a roller frame; the top of the roller frame is fixedly installed with the hanger; the hanger is detachably installed at the bottom of the C-shaped frame top plate; the C-shaped frame and the support plate are integrally formed; the cooperation between the rollers at the bottom of the two roller frames and the conveyor belt effectively ensures that the conveyor belt can contact both ends of the cardboard during the conveying process, thereby effectively ensuring the conveying effect. At the same time, the downward pressure of the rollers can effectively prevent the cardboard from sagging in the middle during the conveying process.

[0005] As a further technical solution of this utility model, a crease assembly is provided at the middle position of the end of the two conveyor frames away from the feeding assembly; the crease assembly includes a carrier plate; the carrier plate is fixedly installed to the support plate via a base plate; a double round head frame is provided at the bottom of the carrier plate; a mating belt is fitted on the double round head frame; the double round head frame is fixedly installed to the support hanging plate; multiple pulleys are symmetrically arranged on both sides of the support hanging plate; the multiple pulleys are connected by belts; when the cardboard is conveyed to the bottom of the crease assembly, the carrier plate, mating belt and cardboard make effective contact, and at the same time, when the rotating shaft drives the conveyor belt to rotate, it is also connected to the drive shaft, so as to effectively realize the rotation of the creasing wheel coaxially installed on one of the pulleys through the cooperation between the belt and the pulleys, thereby ensuring the creasing quality of the cardboard.

[0006] As a further technical solution of this utility model, one of the pulleys is fixedly installed with the drive shaft, and an indentation wheel is coaxially arranged on the pulley below the drive shaft; the indentation wheel is coaxially arranged with one of the pulleys, so that the drive shaft drives one pulley to rotate, and multiple pulleys are effectively coordinated through belts, thereby effectively achieving the synchronous rotation effect of the indentation wheel; As a further technical solution of this utility model, a mounting frame is provided at the top of the end of the transmission frame away from the feeding component; the side wall of the mounting frame is fixedly installed to the connecting plate by a hanger; multiple sets of pressure rollers are provided at the bottom of the mounting frame; and a mating belt is also fitted on the mounting frame.

[0007] As a further technical solution of this utility model, the feeding component includes a frame; the top of the frame is provided with multiple support plates; a feeding belt is installed between two adjacent support plates; a rear baffle is adjustablely installed on one side of the support plate; two symmetrical side plates are fixedly installed on the frame, and the cooperation between the rear baffle and the two side plates effectively prevents the cardboard from becoming loose on the support plates, thereby effectively ensuring the stability of feeding.

[0008] As a further technical solution of this utility model, a crossbeam is fixedly installed between the two upright plates on the base; two fixing frames are detachably installed on the crossbeam; a front baffle is detachably installed inside each of the two fixing frames by bolts; the front baffle effectively ensures that the cardboard will not tilt forward on the support plate, thereby ensuring the stability between the cardboards; the front baffle cooperates with the fixing frame on the cross plate by bolts, and by adjusting the distance between the front baffle and the rear baffle, the limiting feeding effect of cardboard of different sizes can be effectively achieved.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, the cardboard is placed on the support plate, and the cardboard is effectively limited by the rear baffle installed on the support plate and the front baffle installed on the crossbeam, thereby ensuring the stability of the cardboard during feeding. The cardboard is conveyed forward by the feeding belt between two adjacent support plates through the rotating shaft installed at one end of the frame. After the cardboard is separated from the feeding component, it is driven to the end away from the feeding component by the conveyor belt on the two conveyor frames. 2. In this utility model, during transmission, both ends of the cardboard are located between the conveyor belt and the rollers at the bottom of the roller frame. This effectively ensures the flatness of the cardboard and also effectively prevents the cardboard from sagging in the middle during transmission. After the cardboard separates from the rollers at the bottom of the roller frame, the cardboard is then transported by the mating belt and pressure rollers set on the mounting frame. 3. In this utility model, the carrier plate and mating belt in the crease assembly set between two mounting frames are synchronously transported in contact with the cardboard. At the same time, when the conveyor belt inside the conveyor frame is transported, the rotating shaft at one end also drives the drive shaft to rotate via a chain. The drive shaft is installed with multiple pulleys through belt cooperation. The creasing wheel coaxially mounted on one of the pulleys rotates synchronously, thereby effectively creasing the crease position of the cardboard, thus effectively ensuring the quality of subsequent work and effectively improving production efficiency.

The feeding belt 22 between two adjacent support plates 21 is realized through the rotating shaft installed at one end of the frame 20 to transport the cardboard forward. After the cardboard is separated from the feeding component 2, it is driven to the end away from the feeding component 2 by the conveyor belt 34 on the two conveyor frames 30.

[0021] In this embodiment, one of the pulleys 44 is fixedly installed with the drive shaft 45, and an indentation wheel 42 is coaxially provided on the pulley 44 below the drive shaft 45.

This effectively ensures the flatness of the cardboard and also effectively prevents the cardboard from sagging in the middle during transmission. After the cardboard separates from the rollers at the bottom of the roller frame 32, the cardboard is then transported by the mating belt 35 and pressure roller 310 set on the mounting frame 311. The carrier plate 40 and the mating belt 41 in the creasing assembly 4 set between the two mounting frames 311 are synchronously transported in contact with the cardboard. At the same time, when the conveyor belt 34 inside the conveyor frame 30 is transported, the rotating shaft 37 at one end also drives the drive shaft 45 to rotate through the chain. The drive shaft 45 is installed in cooperation with multiple pulleys 44 through belts 43. The creasing wheel 42 coaxially mounted on one of the pulleys 44 rotates synchronously, thereby effectively creasing the bending position of the cardboard, thus effectively ensuring the quality of subsequent work and effectively improving production efficiency.
