[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The main steps of carton machine production usually include the following stages: 1. Paper feeding stage: First, the cardboard is fed into the processing area of ​​the carton machine through the paper feeding equipment; 2. Slotting and folding: In this stage, according to the preset specifications and drawings, the cardboard is slotted and folded to make it the basic shape of the carton; 3. Bonding stage: Next, use an adhesive (such as glue) to bond the edges of the cardboard together to fix the shape; 4. Forming and flattening: Flatten the bonded cardboard to ensure that the edges of the carton are firm and the shape is regular, and the paper feeding equipment is one of the indispensable equipment in the carton production process.

[0023] Embodiment 1:

[0024] Based on the technical defects of the existing technology that the cardboard is easily damaged due to the clamping method of conveying the cardboard, please refer to Figure 1-Figure 4 The utility model provides a paper feeding device for a carton machine, which uses a suction cup 414 to absorb cardboard, so that the cardboard is placed one by one on the conveying mechanism 6, which can realize the rapid feeding of cardboard, and the surface of the cardboard is not easily damaged, which can improve the production quality of the carton. A lifting mechanism 2 for compensating the height of the cardboard is provided on the inner side of the frame 1, and a side panel 3 is installed on the frame 1. A feeding mechanism 4 for carrying the cardboards one by one is fixed on the front of the side panel 3. An extension table 5 is also fixed on one side of the frame 1, and a conveying mechanism 6 for conveying the cardboard is provided on the inner side of the extension table 5; the bundles of cardboard are stacked on the lifting mechanism 2, and then the feeding mechanism 4 is moved to gradually place the cardboard on the conveying mechanism 6, and the cardboards are fed into the carton machine one by one by using the conveying mechanism 6.

[0025] In order to ensure that the cards can be fed into the carton machine one by one, a feeding mechanism 4 is set to transport the cards one by one, and the feeding mechanism 4 includes a motor 2 41 installed at the bottom of the side panel 3, and a reciprocating moving component is connected to the output shaft of the motor 2 41, and two groups of adsorption components that are in contact with the surface of the cardboard are connected to the reciprocating moving component. The motor 2 41 works and drives the adsorption component to move through the reciprocating moving component. When the adsorption component contacts the surface of the cardboard, the top layer of the cardboard can be sucked, and then the two groups of adsorption components can be reciprocated to place the cardboards one by one on the conveying mechanism 6.

[0026] As the number of cardboards decreases, the height of the cardboards on the lifting mechanism 2 will decrease, while the height of the suction cup moving each time is the same, and the problem that the suction cup cannot touch the cardboard will occur. In order to solve this problem, a lifting mechanism 2 is set, and the lifting mechanism 2 includes a motor 21 installed at the bottom of the frame 1, and a screw 22 is fixedly provided on the output shaft of the motor 21. The top of the screw 22 is rotatably connected to the inner side of the frame 1 through a bearing seat 23. A screw sleeve 24 is spirally connected to the outer wall of the screw 22. The screw sleeve 24 is fixed on the lifting arm 25, and the lifting arm 25 is slidably set on one side of the frame 1. The motor 21 is used to drive the screw 22 to rotate, and the screw 22 drives the lifting arm 25 to move upward through the spiral transmission action with the screw sleeve 24, thereby gradually compensating for the height of the cardboard, so that the topmost cardboard can always be in contact with the suction cup.

[0027] In order to facilitate the control of the reciprocating movement of the adsorption component, a moving component is set up, and the moving component includes a rotating arm 42 whose one end is fixedly connected to the output shaft of the second motor 41, and a movable hole is opened on the rotating arm 42. A guide rod 43 is slidably set in the movable hole. One end of the guide rod 43 is slidably set in the guide groove on the inner side of the guide rail 44, and the guide rail 44 is installed on the side plate 3 through a fixed block 45. The other end of the guide rod 43 is fixedly connected to a spline shaft 46, and a movable plate 410 is fixedly provided at the bottom of the spline shaft 46. Both ends of the movable plate 410 are connected to the adsorption component; the second motor 41 can control the reciprocating swing of the rotating arm 42, and the rotating arm 42 drives the spline shaft 46 to reciprocate through the guide rod. Since the guide rod is limited by the guide groove on the inner side of the guide rail 44, the adsorption component moves along the guide groove to complete the feeding work.

[0028] To ensure the stability of the adsorption assembly during the reciprocating movement, a spline sleeve 47 is provided on the top of the spline shaft 46. The spline sleeve 47 is fixedly connected to a slider 48. The slider 48 is slidably arranged on the inner side of a slide rail 49. The slide rail 49 is installed on the side panel 3 through a bracket. The limiting effect between the spline shaft 46 and the spline sleeve 47 can limit the rotation of the spline shaft 46 without affecting the lifting movement. At the same time, the slider 48 and the slide rail 49 make the adsorption assembly more stable during horizontal movement.

[0029] In order to ensure that the cardboard can be fixed, an adsorption component is set up, and the adsorption component includes a connecting column 411 inserted at one end of the movable plate 410, the top of the connecting column 411 is threadedly connected with a nut 412, and the bottom of the connecting column 411 is fixed with a mounting plate 413, and both ends of the mounting plate 413 are installed with suction cups 414; the suction cups 414 are used to contact with the cardboard, so that the cardboard is adsorbed and fixed for subsequent transportation.

[0030] Embodiment 2:

[0031] Since the cardboard needs to be fed into the carton machine, and there is still a certain distance for the cardboard to enter the carton machine, to ensure that the cardboard can enter the carton machine smoothly, please refer to Figure 1 and Figure 4 On the basis of the first embodiment, the conveying mechanism 6 includes a roller shaft 61 rotatably connected to the frame 1 and the inner side of the extension table 5, a plurality of conveyor belts 52 are transmission-connected between the two roller shafts 61, and a motor 3 63 fixedly connected to one end of the roller shaft 61 is installed on the side wall of the frame 1; the extension table 5 is placed inside the paper inlet of the carton machine, and then the cardboard can smoothly enter the carton machine under the action of the conveyor belt 52.

[0032] Through the above embodiments, it can be known that the use process of the device is as follows: when conveying cardboard, the motor 2 41 is used to control the reciprocating swing of the rotating arm 42, and the rotating arm 42 drives the spline shaft 46 to reciprocate through the guide rod. Since the guide rod is limited by the guide groove on the inner side of the guide rail 44, the adsorption component moves along the guide groove, and the adsorption component on the left side can place the cardboard on the frame 1, and then the adsorption component on the right side can place the cardboard on the conveying mechanism 6. At this time, the motor 3 63 is used to work and drive the conveyor belt 52 to move through the roller 61, so that the cardboard can be delivered to the inside of the carton machine. As the number of cardboards decreases, the height of the cardboard on the lifting mechanism 2 will decrease. At this time, the motor 1 21 is used to drive the screw 22 to rotate, and the screw 22 drives the lifting arm 25 to move upward through the spiral transmission action with the screw sleeve 24, thereby gradually compensating for the reduced height of the cardboard, so that the top cardboard can always be in contact with the suction cup.

[0033] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
