Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery technology, and in particular to a device for folding paper. Background Technology

[0002] Patent document CN 207943250 U discloses a fully automatic instruction manual conveying device. This device uses a paper folding machine to fold the instruction manuals and convey them to a flat belt conveyor for clamping the manuals. The manuals are then transported to subsequent equipment via a clamping conveyor chain. This technical solution has a high degree of automation, which is beneficial for improving production efficiency. However, it has several drawbacks. Since the paper folding machine and the flat belt conveyor are an integrated structure, sharing a single motor and multiple synchronous belt drive mechanisms for power transmission, maintenance of the paper folding machine or replacement of the internal folding boards to accommodate different paper sizes requires removing the entire device. This is inconvenient, time-consuming, and labor-intensive. Furthermore, because it uses two synchronously running belts for clamping and conveying, the clamping force cannot be set too high to avoid damaging the folded paper. Therefore, the folded paper may slip during conveying, resulting in inconsistent conveying speed and poor stability. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a device with a simple structure that is easy to maintain and replace folded paper of different specifications.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A paper folding device includes a frame, a paper folding mechanism, and a first driving member disposed on the paper folding mechanism. The frame is provided with a sliding mechanism, the paper folding mechanism is disposed on the sliding mechanism, and the frame is provided with a second driving member and a feeding conveying mechanism connected to the second driving member.

[0006] As a further improvement to the above technical solution: the sliding mechanism includes a slide rail disposed on the frame and a slide base disposed on the slide rail, and the folding mechanism is disposed on the slide base.

[0007] As a further improvement to the above technical solution: the slide is provided with a limiting plate, and the end of the limiting plate is provided with a limiting part that cooperates with the frame.

[0008] As a further improvement to the above technical solution: the folding mechanism is provided with a connecting plate, which is detachably connected to the frame.

[0009] As a further improvement to the above technical solution: the connecting plate is provided with a locking handle, which is threadedly connected to the frame.

[0010] As a further improvement to the above technical solution: the folding mechanism is provided with a transition conveying mechanism, the first driving member is connected to the transition conveying mechanism, one end of the feeding conveying mechanism is connected to the transition conveying mechanism, and the other end is provided with a folding paper outlet. The frame is also provided with an adjustment mechanism for adjusting the folding paper conveying speed at the folding paper outlet.

[0011] As a further improvement to the above technical solution: the feeding and conveying mechanism includes an inner synchronous belt and an outer synchronous belt that operates synchronously with the inner synchronous belt, the adjusting mechanism includes an adjusting synchronous belt, the operating speed of the adjusting synchronous belt is less than the operating speed of the inner synchronous belt, and multiple adjusting baffles are evenly arranged on the adjusting synchronous belt.

[0012] As a further improvement to the above technical solution: both the inner synchronous belt and the outer synchronous belt are provided with two columns arranged in a one-to-one correspondence, and the adjusting baffle is located between the two columns of the inner synchronous belt.

[0013] As a further improvement to the above technical solution: the active pulley of the adjusting synchronous belt is connected to the second driving component.

[0014] As a further improvement to the above technical solution: both the first driving component and the second driving component are servo motors.

[0015] Compared with the prior art, the advantages of the present invention are as follows: The paper folding device disclosed in the present invention is powered by a first driving member and a second driving member, respectively. There is no need to set a transmission mechanism between the feeding conveying mechanism and the first driving member. At the same time, the first driving member is set on the paper folding mechanism, while the second driving member is set on the frame. The paper folding mechanism is set on the sliding mechanism of the frame. The overall structure is simple. When it is necessary to maintain the paper folding mechanism or change the specifications of the internal folding paperboard, it is only necessary to slide the paper folding mechanism out relative to the frame. The feeding conveying mechanism does not need to be moved out and will not obstruct the sliding of the paper folding mechanism, making the operation more convenient and efficient.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Figures 1 to 5 An embodiment of the paper-folding apparatus of the present invention is shown. This embodiment includes a frame 1, a paper-folding mechanism 2, and a first driving member 21 disposed on the paper-folding mechanism 2. The frame 1 is provided with a sliding mechanism, and the paper-folding mechanism 2 is disposed on the sliding mechanism. The frame 1 is provided with a second driving member 11 and a feeding conveying mechanism 4 connected to the second driving member 11. The structure of the paper-folding mechanism 2 is the same as in the prior art and will not be described in detail here.

[0024] In this embodiment, the paper folding device 2 and the feeding conveying mechanism 4 are powered by the first driving member 21 and the second driving member 11, respectively. There is no need to set a transmission mechanism between the feeding conveying mechanism 4 and the first driving member 21. The first driving member 21 is set on the paper folding mechanism 2, while the second driving member 11 is set on the frame 1. The paper folding mechanism 2 is set on the sliding mechanism of the frame 1. The overall structure is simple. When it is necessary to maintain the paper folding mechanism 2 or change the specifications of the internal folding paperboard, it is only necessary to slide the paper folding mechanism 2 out relative to the frame 1. The feeding conveying mechanism 4 does not need to be moved out and will not obstruct the sliding of the paper folding mechanism 2, making the operation more convenient and efficient.

[0025] Furthermore, in this embodiment, the sliding mechanism includes a slide rail 12 mounted on the frame 1 and a slide block 22 mounted on the slide rail 12, with the folding mechanism 2 mounted on the slide block 22. See details below. Figure 4 and Figure 5 When the origami mechanism 2 needs to be moved out, the slide block 22 slides on the slide rail 12, which can provide guidance for the origami mechanism 2 and reduce frictional resistance, making the movement of the origami mechanism 2 more stable and smooth.

[0026] In a preferred embodiment, the slide 22 is provided with a limiting plate 23, and the end of the limiting plate 23 is provided with a limiting part 24 that cooperates with the frame 1. When the limiting part 24 abuts against the frame 1, the slide 22 can no longer slide, indicating that the stroke of the folding mechanism 2 has reached its maximum value, thereby preventing the folding mechanism 2 from falling off the frame 1 and improving safety and reliability.

[0027] Furthermore, in this embodiment, the folding mechanism 2 is provided with a connecting plate 25, which is detachably connected to the frame 1. Preferably, the connecting plate 25 is provided with a locking handle 26, which is threadedly connected to the frame 1, and the connecting plate 25 is also provided with a push-pull handle 27. When the locking handle 26 is tightened on the frame 1, the folding mechanism 2 cannot slide relative to the frame 1, thus preventing accidental movement of the folding mechanism 2 during operation. The structure is simple and reliable. When the folding mechanism 2 needs to be moved out, the locking handle 26 is loosened first, and then the folding mechanism 2 is pulled out using the push-pull handle 27, which is convenient to use. Of course, in other embodiments, a buckle or similar device can also be used to achieve a detachable connection between the connecting plate 25 and the frame 1.

[0028] Furthermore, in this embodiment, the folding mechanism 2 is equipped with a transition conveying mechanism 3. The first driving member 21 is connected to the transition conveying mechanism 3 (that is, the transition conveying mechanism 3 is also powered by the first driving member 21, avoiding the need for additional driving members and saving costs. Specifically, power transmission can be achieved through a synchronous belt mechanism, etc.). One end of the unloading conveying mechanism 4 is connected to the transition conveying mechanism 3, and the other end is equipped with a folded paper outlet 43. The frame 1 is also equipped with an adjustment mechanism 5 for adjusting the folded paper conveying speed at the folded paper outlet 43. The folding mechanism 2 completes the folding of paper (e.g., instructions for medicine), and then conveys the folded paper to the transition conveying mechanism 3. The transition conveying mechanism 3 then conveys the paper to the unloading conveying mechanism 4. When the folded paper is conveyed to the folded paper outlet 43, the output speed is adjusted by the adjustment mechanism 5 to keep the output speed of the folded paper stable and consistent, eliminating the influence of slippage and other problems during the conveying process, which is beneficial to the stable operation of downstream equipment.

[0029] In a preferred embodiment, the feeding conveyor 4 includes an inner synchronous belt 41 and an outer synchronous belt 42 that operates synchronously with the inner synchronous belt 41 (i.e., the inner synchronous belt 41 and the outer synchronous belt 42, which operate synchronously, clamp and convey the folded paper from both the inner and outer sides). The adjusting mechanism 5 includes an adjusting synchronous belt 51, the operating speed of which is less than that of the inner synchronous belt 41. Multiple adjusting baffles 52 are evenly arranged on the adjusting synchronous belt 51. When the folded paper is conveyed to the folded paper outlet 43 at a relatively high speed, it is blocked by the adjusting baffle 52 and slowed down. Then, it moves synchronously with the adjusting baffle 52 and is output at this speed. Similarly, the output speed of the next folded paper is controlled by the next adjusting baffle 52. This cycle ensures that all folded paper is output at the speed of the adjusting baffle 52, eliminating the effects of slippage during the feeding conveyor 4 and the transition conveyor 3 (the transition conveyor 3 can also be conveyed by clamping two synchronous belts). The structure is simple and reliable.

[0030] In a preferred embodiment, both the inner synchronous belt 41 and the outer synchronous belt 42 are provided with two rows arranged in a one-to-one correspondence. The adjusting baffle 52 is located between the two rows of inner synchronous belts 41. While adjusting the output speed of the folded paper, the adjusting baffle 52 can also adjust the position of the folded paper to avoid skewing, achieving two goals at once.

[0031] Furthermore, in this embodiment, the driving pulley of the adjusting synchronous belt 51 is connected to the second driving member 11 (that is, the adjusting synchronous belt 51 is also powered by the second driving member 11, avoiding the need for additional driving members and saving costs. Specifically, power transmission can be achieved through a synchronous belt mechanism or the like).

[0032] In a preferred embodiment, both the first drive component 21 and the second drive component 11 are servo motors. Servo motors offer high motion precision and are easy to automate. Of course, in other embodiments, other existing drive components can also be used to drive the folding mechanism 2, the transition conveying mechanism 3, and the unloading conveying mechanism 4.

[0033] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
