Description

Technical Field

[0001] This utility model relates to the field of folding machine technology, and in particular to a folding machine that avoids paper jams. Background Technology

[0002] Folding machines are mainly used for folding papers of various sizes and thicknesses within the design scope. They are suitable for high-volume folding in fast printing centers, manufacturing enterprises, official documents, and business letters.

[0003] Currently, existing folding machines use two limiting plates on the feed plate to prevent paper from tilting during feeding. Each limiting plate has a slider fixed to its bottom, which embeds into linear grooves on both sides of the folding box, allowing for horizontal movement. The positions of the two limiting plates are adjusted individually using markings on the feed plate surface to accommodate different paper sizes. However, this individual adjustment method is cumbersome, requiring separate operation of each limiting plate and hindering the rapid adjustment of their spacing at once. Further optimization is needed.

[0004] Therefore, this application provides a folding machine that avoids paper jams to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a folding machine that avoids paper jams, thereby solving the problem that existing folding machines are inconvenient to quickly adjust the spacing of the limit plates on the feed plate to adapt to paper specifications.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A folding machine for avoiding paper jams includes a folding box, on which a feeding plate and a dropping plate are provided. Two symmetrical grooves are formed on the center of the surface of the feeding plate perpendicular to the feeding direction. Limiting plates are slidably installed on the two grooves. An adjusting rod is rotatably installed in both grooves. A slider is fixed at the bottom of the limiting plate and slidably embedded in the groove. The adjusting rod has two symmetrically constructed opposite threads in the two grooves. The threads of the adjusting rod in the grooves pass through the slider at the bottom of the limiting plate.

[0008] The feed plate is provided with an electrostatic elimination plate at the feed inlet. The lower end face of the electrostatic elimination plate is provided with a movable plate that can be raised and lowered. The lower end face of the movable plate is provided with conductive wires for abutting against the surface of the paper.

[0009] Optionally, the surface of the feed plate is provided with a scale, and the two limiting plates are symmetrically distributed on the scale.

[0010] Optionally, one end of the adjusting rod extends beyond the side of the feed plate and is fixed with a screw cap.

[0011] Optionally, two vertical guide posts are symmetrically fixed at both ends of the upper surface of the movable plate, and the two guide posts vertically penetrate the static elimination plate.

[0012] Optionally, a fixing frame is fixed to the middle of the upper end face of the movable plate, and a vertical threaded column is rotatably installed on the top of the fixing frame, the threaded column threaded through the static elimination plate.

[0013] Optionally, an electrostatic discharge mechanism is installed inside the fixing frame, and the electrostatic discharge mechanism is electrically connected to the conductive wire.

[0014] Optionally, the electrostatic discharge mechanism includes a capacitor and an LED light.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the cooperation of the slide, the limiting plate and the adjusting rod, the two limiting plates can be driven to move in a mirror image by rotating the adjusting rod at the same time, so as to quickly adjust the distance between the two limiting plates, so that it can quickly adapt to the limiting of different paper sizes and avoid the problem of paper jam caused by the paper being skewed when entering the folding box.

[0017] In the above solution, thanks to the setting of the static elimination plate, the conductive wire on the lower end of the movable plate can be used to abut against the paper entering the folding box to eliminate static electricity, thus avoiding paper jams caused by static sticking and paper accumulation at the roller inlet.

[0018] In summary, this device can not only quickly adjust the spacing of the limiting plates that limit the paper to prevent it from tilting during feeding, but also automatically eliminate static electricity on the paper during feeding to prevent paper from sticking together, thereby effectively reducing paper jams and providing good performance.

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0028] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0030] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0031] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0032] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a folding machine that avoids paper jams, including a folding box 1. The folding box 1 is provided with a feeding plate 2 and a dropping plate 3. Two sliding grooves 4 are symmetrically opened in the middle of the surface of the feeding plate 2 perpendicular to the feeding direction. Limiting plates 5 are slidably installed on the two sliding grooves 4. Adjusting rods 6 are rotatably installed in the two sliding grooves 4.

[0033] The bottom of the limiting plate 5 is fixed with a slider that slides into the groove 4. The adjusting rod 6 has two symmetrically constructed sections with opposite threads within the two grooves 4. The adjusting rod 6 in the groove 4 passes through the slider at the bottom of the limiting plate 5, and one end of the adjusting rod 6 extends beyond the side of the feed plate 2 and is fixed with a cap. Therefore, the adjusting rod 6 can be rotated by tightening the cap, thereby driving the limiting plates 5 on the two grooves 4 to move in a mirror image, achieving the effect of quickly adjusting the distance between the two limiting plates 5.

[0034] In addition, the surface of the feed plate 2 is provided with a scale 201, and the two limiting plates 5 are symmetrically distributed on the scale 201 so as to assist in adjusting the distance between the two limiting plates 5 by means of the scale 201.

[0035] Cooperate Figure 3 and Figure 4As shown, an electrostatic eliminator plate 7 is provided at the feed inlet of the feed plate 2. A movable plate 8, which can move up and down, is provided on the lower end face of the electrostatic eliminator plate 7. A conductive wire 9 for contacting the paper surface is provided on the lower end face of the movable plate 8. Specifically, two vertical guide posts 801 are symmetrically fixed at both ends of the upper end face of the movable plate 8. The two guide posts 801 vertically penetrate the electrostatic eliminator plate 7, forming a vertical movement.

[0036] A fixing frame 802 is fixed in the middle of the upper end face of the movable plate 8. A vertical threaded post 10 is rotatably installed on the top of the fixing frame 802. The threaded post 10 is threaded through the static elimination plate 7. Therefore, the up and down movement of the movable plate 8 can be controlled by rotating the threaded post 10 to adjust the contact pressure of the conductive wire 9 on the paper at the lower end face of the movable plate 8.

[0037] In addition, an electrostatic discharge mechanism 803 is installed inside the fixing frame 802. The electrostatic discharge mechanism 803 is electrically connected to the conductive wire 9. In a specific implementation, the electrostatic discharge mechanism 803 is equipped with a capacitor and an LED light. The electrostatic discharge is stored in the capacitor by electrically connecting the conductive wire 9 and discharged by the LED light. This can be achieved using a basic electrical structure, which will not be described in detail. In other embodiments, the electrostatic discharge mechanism 803 can also be connected to electricity to achieve electrostatic discharge.

[0038] The working principle provided by this utility model is that the paper-jamming folding machine can directly drive the two limiting plates 5 to move in a mirror image by rotating the adjusting rod 6, thereby quickly adjusting the distance between the two limiting plates 5 so that it can quickly adapt to the limiting of different paper sizes and avoid the problem of paper jamming caused by the paper being skewed when entering the folding box 1.

[0039] Meanwhile, since the feed plate 2 is equipped with an electrostatic elimination plate 7 at the port where it enters the folding box 1, the movable plate 8 can use the conductive wire 9 installed on its lower end face to abut against the paper entering the folding box 1, and eliminate the static electricity on its surface by guiding it into the electrostatic release mechanism 803, so as to avoid the paper from sticking together due to static electricity and causing paper jams at the roller inlet.

[0040] In summary, this device can not only quickly adjust the spacing of the limiting plates 5 that limit the paper to prevent it from tilting during feeding, but also automatically eliminate static electricity on the paper during feeding to prevent paper from sticking together, thereby effectively reducing paper jams and achieving good performance.

[0041] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
