The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.
[0025] Please see Figure 1 The paper feeding device provided by this utility model will now be described. The paper feeding device includes a conveyor belt 10, a rotating frame 20, a pushing component 30, and a feeding component 40; the conveyor belt 10 is used to transport the paper after feeding; the rotating frame 20 is located at one end of the conveyor belt 10, and multiple carriers 21 are spaced apart along its circumference, each carrier 21 being used to hold different types of paper; the rotating frame 20 has a feeding plate 221 that is flush with the height of the conveyor belt 10, and the rotating frame 20 is used to drive each carrier 21 to rotate sequentially until it is aligned with the feeding plate 221; the pushing component 30 is located on the rotating frame 20 and is used to push the paper placed on the carrier 21 aligned with the feeding plate 221 onto the feeding plate 221; the feeding component 40 is located on the conveyor belt 10 and is used to transfer the paper on the feeding plate 221 to the conveyor belt 10.
[0026] It should be noted that the rotating frame 20 is equipped with multiple carriers 21 spaced circumferentially, and each carrier 21 can hold different types of paper. By rotating the frame 20, multiple types of paper can be sequentially conveyed to the feeding plate 221, which is level with the conveyor belt 10. This allows for the feeding of multiple types of paper on a single device, greatly improving the efficiency of paper supply. Since only one device is involved, compared to multiple feeding devices, maintenance and management are simplified, reducing training costs and labor input, and making troubleshooting and repair of device malfunctions more convenient and faster.
[0027] The beneficial effects of the paperboard feeding device provided by this utility model are as follows: Compared with the prior art, the rotating frame 20 in this utility model is provided with multiple carriers 21 spaced apart along the circumference, and each carrier 21 can hold different types of paper. By rotating the rotating frame 20, multiple types of paper can be conveyed sequentially to the feeding plate 221, which is level with the height of the conveyor belt 10. Multiple types of paper can be fed through one device, improving the efficiency of paper supply and meeting the diverse production needs of paperboard products. Through the design of the rotating frame 20 and the carriers 21, the storage and feeding functions of multiple types of paper are integrated into one device, which can save space, make reasonable use of limited space, and improve space utilization.
[0028] In one possible implementation, please refer to Figure 2 The rotating frame 20 includes a ring frame 22, a rotating frame 23, a rotary drive component 24, and multiple load-bearing components 21. The ring frame 22 is fixedly connected to one end of the conveyor belt 10, and the ring frame 22 is provided with a feeding plate 221 and a pushing assembly 30. The rotating frame 23 is rotatably connected inside the ring frame 22, and the rotating frame 23 is provided with multiple rotating shafts 231 at intervals along its circumference. Each rotating shaft 231 is rotatably connected to one of the load-bearing components 21. The rotary drive component 24 is provided on the ring frame 22, and its output end is connected to the rotating frame 23.
[0029] It should be noted that the rotating frame 23 is rotatably connected to multiple carrier components 21 via a rotating shaft 231. Under the action of the rotating drive component 24, it can achieve smooth and precise rotation. This allows the paper in different carrier components 21 to rotate precisely in a preset order to align with the feed plate 221 on the ring frame 22. By precisely controlling the rotation angle and speed of the rotating frame 23 through the rotating drive component 24, specific types of paper can be quickly conveyed to the feed plate 221, improving the response speed of paper supply and increasing sales efficiency. The rotating frame 20 has a good modular structure. The ring frame 22, rotating frame 23, rotating drive component 24, and carrier components 21 are relatively independent yet cooperate with each other. They can be assembled and debugged separately during equipment installation. During the installation of the ring frame 22, the ring frame 22 is first fixed to one end of the conveyor belt 10, then the rotating frame 23 and rotating drive component 24 are installed, and finally the carrier components 21 are connected. Each step is simple and clear, reducing installation difficulty. During the debugging process, if a problem is found in a certain part, that part can be adjusted and repaired separately without affecting the normal operation of other parts.
[0030] In some embodiments, please refer to Figure 2 and Figure 3 The support member 21 includes a support frame 211 and a support plate 213; a bushing 212 is provided above the support frame 211, and the bushing 212 is rotatably sleeved on the rotating shaft 231; the support plate 213 is used to place paper.
[0031] It should be noted that the support frame 211, in conjunction with the carrier plate 213, provides a stable and suitable placement platform for the paper. The flat surface of the carrier plate 213 ensures that the paper remains neatly arranged during placement, preventing slippage or misalignment due to unstable placement, effectively preventing paper damage and maintaining paper integrity. The bushing 212 above the support frame 211 rotatably mounts onto the rotating shaft 231, allowing the carrier component 21 to rotate flexibly and smoothly under the drive of the rotating frame 23. This rotatable connection reduces friction generated during the rotation of the rotating frame 20, making the rotation of the carrier component 21 more stable. When the rotary drive 24 drives the rotating frame 23 to rotate, the carrier component 21 can easily follow the rotation, accurately transferring the paper on the carrier plate 213 to the alignment position with the feed plate 221, improving the efficiency and accuracy of paper switching supply. The design of the carrier plate 213 has strong versatility and expandability. By adjusting the size and shape of the carrier plate 213 and its mounting method on the support frame 211, it can easily accommodate paper of different specifications and sizes. Whether the paper is small, medium, or large, it can be properly placed on the carrier plate 213.
[0032] For example, please refer to Figure 4 The ring frame 22 is equipped with a lifting drive 222. The output end of the lifting drive 222 is vertically upward and connected to the loading plate 221.
[0033] It should be noted that the lifting drive unit 222 installed on the ring frame 22 can precisely control the height of the feeding plate 221. During the paper feeding process, the stacking thickness of different batches of paper may vary, or the height of the feeding plate 221 needs to be adapted due to minor adjustments to the height of the conveyor belt 10 when connecting with it. When the thickness of a new batch of paper is slightly thicker than that of the previous batch, the lifting drive unit 222 raises the feeding plate 221 to a suitable height, ensuring that the pushing component 30 can smoothly push the paper from the carrier 21 to the feeding plate 221, while ensuring that the feeding component 40 can accurately grab the paper and transfer it to the conveyor belt 10, avoiding paper falling or feeding difficulties due to height differences, and improving the flexibility and accuracy of the feeding operation. The lifting drive unit 222 can also achieve seamless docking with other equipment by precisely controlling the height of the feeding plate 221, improving the continuity and automation of the entire paper sales and post-processing process. When the feeding assembly 30 pushes the paper onto the feed plate 221, if the height of the feed plate 221 is not appropriate, excessive friction may occur between the paper and the carrier 21 or the feed plate 221 during the feeding process. This not only affects the paper quality but also accelerates the wear of the feeding assembly 30. By precisely controlling the height of the feed plate 221, the feeding process is made smoother, and the wear of mechanical parts is reduced.
[0034] For example, please refer to Figure 4 The feeding assembly 30 includes a first telescopic drive member 31 and a push plate 32; the first telescopic drive member 31 is disposed on the rotating frame 20 and located on the side of the feeding plate 221 away from the conveyor belt 10; the push plate 32 is connected to the output end of the first telescopic drive member 31 and is horizontally aligned with the feeding plate 221.
[0035] It should be noted that the first telescopic drive 31 drives the push plate 32 to perform a feeding motion, enabling precise paper pushing. When the carrier 21 rotates to the position aligned with the feed plate 221, the first telescopic drive 31 is activated, and its output end pushes the push plate 32, smoothly pushing the paper placed on the carrier 21 onto the feed plate 221. The pushing assembly 30 can push different types of paper onto the feed plate 221 one by one in a fast and stable manner according to a set frequency, meeting the high-frequency feeding requirements and ensuring that the conveyor belt 10 can continuously and efficiently transport the paper after feeding, thus improving the paper feeding efficiency. The first telescopic drive 31 is located on the side of the feed plate 221 away from the conveyor belt 10, and the pushing direction of the pushing assembly 30 is consistent with the final conveying direction of the paper, reducing the possible deviation or jamming of the paper due to changes in direction during the pushing process. The pusher plate 32 acts directly on the paper, ensuring that the pushing force is evenly distributed on the paper, avoiding paper damage or stacking disorder caused by uneven local force, and ensuring the integrity of the paper and the accuracy of feeding.
[0036] In one possible implementation, please refer to Figure 5 The feeding assembly 40 includes a mounting frame 41 and a suction cup structure 42. The mounting frame 41 is mounted on the conveyor belt 10, and the suction cup structure 42 is mounted on the mounting frame 41 and located above the feeding plate 221.
[0037] It should be noted that the suction cup structure 42 is located above the feeding plate 221, enabling precise gripping of the paper placed on the feeding plate 221. The suction cup structure 42 can evenly adhere to the paper surface, ensuring the stability and reliability of the gripping process, preventing the paper from falling or being damaged during gripping and transfer, and ensuring the accuracy and integrity of paper feeding.
[0038] In some embodiments, please refer to Figure 5 The suction cup structure 42 includes a slider 421, a second telescopic drive member 422, an adsorption plate 423, and a vacuum device 424. The slider 421 is horizontally slidably connected to the mounting frame 41. The second telescopic drive member 422 is located on the mounting frame 41, and its output end is connected to the slider 421. The adsorption plate 423 is located at the bottom of the slider 421. The vacuum device 424 is located on the slider 421 and is connected to the adsorption plate 423.
[0039] It should be noted that the vacuum device 424 can be a piston-type air pump, which extracts air from the adsorption plate 423 through the reciprocating motion of the piston. This type of air pump allows for adjustment of the piston's movement frequency and stroke as needed, thereby flexibly controlling the adsorption force. It is particularly suitable for applications requiring precise adjustment of adsorption force, especially when simultaneously gripping different types of paper. The slider 421 is horizontally connected to the mounting frame 41, and in conjunction with the second telescopic drive 422, enables precise horizontal positioning of the adsorption plate 423. During paper feeding, slight deviations may occur in the position of different batches of paper on the feeding plate 221. By controlling the slider 421 to slide using the second telescopic drive 422, the adsorption plate 423 can be accurately moved directly above the paper, ensuring reliable gripping. This guarantees accurate gripping every time, improving the accuracy and stability of feeding. The adsorption plate 423 can flexibly adapt to different paper arrangements. Whether the paper is arranged in a single row or multiple rows, by adjusting the position of the slider 421, the suction plate 423 can pick up the paper in different positions as needed, meet diverse feeding requirements, and improve feeding efficiency.
[0040] For example, please refer to Figure 5 The mounting bracket 41 is provided with a horizontal sliding groove 411, and the slider 421 slides and fits against the inner wall of the sliding groove 411.
[0041] It should be noted that the chute 411 provides a precise movement track for the slider 421, making its horizontal movement smoother and more accurate. During the paper feeding process, whether adjusting the suction plate 423 to grip the paper directly above it or switching between gripping papers at different positions, the slider 421 can move accurately along the guide of the chute 411. When multiple rows of papers need to be gripped sequentially on the feed plate 221, the slider 421 can move along a stable trajectory under the constraint of the chute 411, ensuring that the suction plate 423 is accurately positioned above each sheet of paper, improving the accuracy of the gripping position, and thus enhancing the stability and reliability of the feeding process.
[0042] For example, please refer to Figure 4 The rotating frame 20 is equipped with a position sensor 223, which is used to detect the rotation position of the support 21.
[0043] It should be noted that the position sensor 223 can monitor the position information of the carrier 21 in real time. When the carrier 21 approaches the feeding plate 221 as the rotating frame 20 rotates, the sensor quickly detects its position change. During the paper sales process, various types of paper are stored in different carriers 21. When a specific type of paper needs to be fed, the rotating frame 20 starts to rotate. The position sensor 223 accurately senses the rotation angle and position of the carrier 21. Once the carrier 21 reaches the position precisely aligned with the feeding plate 221, the position sensor 223 immediately sends a signal to control the rotation drive 24 to stop working, ensuring that the carrier 21 stops accurately. This allows the paper in the carrier 21 to be accurately pushed to the feeding plate 221 by the pusher assembly 30, avoiding misalignment of the paper due to positional deviation of the carrier 21 and improving the accuracy of paper feeding.
[0044] In one possible implementation, please refer to Figure 2 The paperboard feeding device also includes a controller 50, which is electrically connected to the rotating frame 20, the position sensor 223, the pushing component 30, and the feeding component 40.
[0045] It should be noted that the controller 50 is electrically connected to the rotary drive 24 on the ring frame 22, and can precisely control the rotation of the rotating frame 20 based on the signal fed back by the position sensor 223. When the position sensor 223 detects that the carrier 21 carrying the paper has reached the position aligned with the feeding plate 221, the controller 50 can promptly send a command to stop the rotary drive 24, ensuring that the carrier 21 accurately stops at the aligned position on the feeding plate 221, thus achieving precise feeding. The controller 50 is electrically connected to the pushing assembly 30 and the feeding assembly 40, and can coordinate the working sequence and rhythm between the components. After the carrier 21 reaches the designated position, the controller 50 first triggers the pushing assembly 30 to push the paper from the carrier 21 to the feeding plate 221, and then starts the feeding assembly 40 to convey the paper out, so that the entire feeding process proceeds in an orderly manner and improves feeding efficiency.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
