Description

TECHNICAL FIELD

[0001] The utility model relates to printer technical field, concretely relates to printing device and printing system. BACKGROUND

[0002] The file processing device includes a printer, a copier, a scanner and an email gateway. With the increasing demand for printing, the function of the printer is gradually enriched, and the speed and quality are greatly improved. In the double-sided printing function, the most important problem to be solved is the design of the reverse paper path. The cooperation between the tray and the paper winding wheel is particularly important.

[0003] However, the related printer paper outlet paper holding groove is deep, and the paper holding surface is an inclined plane. The printer not only prints ordinary paper, but also applies to books with covers such as booklets. The booklet generally contains multiple pages, and the outermost page is usually a higher gram weight paper product. When printing, the printer generally discharges the printed paper along the upward inclined direction. Affected by high temperature, the outermost page will have a certain warping deformation, and under the action of gravity, the side of the outermost page away from the paper outlet will fall down more. When the higher gram weight paper product falls on the paper holding surface away from the paper outlet, it is easy to cause the contact angle between the paper product and the paper outlet to be too large, resulting in the size and direction of the impact force being offset by the paper discharge force, greatly increasing the probability of paper jam of the printer. SUMMARY

[0004] Therefore, the utility model provides a kind of printing device and printing system to solve the related printer paper outlet paper holding groove is deep, and the paper holding surface is an inclined plane, printer not only prints ordinary paper, but also applies to books with covers such as booklets, booklet generally contains multiple pages, and the outermost page is usually a higher gram weight paper product. When printing, the printer generally discharges the printed paper along the upward inclined direction. Affected by high temperature, the outermost page will have a certain warping deformation, and under the action of gravity, the side of the outermost page away from the paper outlet will fall down more. When the higher gram weight paper product falls on the paper holding surface away from the paper outlet, it is easy to cause the contact angle between the paper product and the paper outlet to be too large, resulting in the size and direction of the impact force being offset by the paper discharge force, greatly increasing the probability of paper jam of the printer.

[0005] In a first aspect, the utility model provides a kind of printing device, comprising:

[0006] Printer body, the printer body is provided with paper outlet, the printer body is also set up paper holding groove corresponding the paper outlet;

[0007] Paper holding tray, the paper holding tray is detachably installed in the paper holding groove, and the top surface of the paper holding tray close to the paper outlet is a paper holding surface.

[0008] Wherein, the distance between the paper supporting surface and the paper outlet gradually decreases in the vertical direction from the direction close to the paper outlet to the direction far from the paper outlet, and the paper supporting surface is arranged in an arc shape.

[0009] Beneficial effects: A paper supporting plate with a certain thickness is arranged. When the paper is discharged from the paper outlet, the paper supporting surface on the paper supporting plate is higher than the top surface of the paper supporting groove. The paper supporting surface can contact the discharged paper earlier than the paper supporting groove. Therefore, the side of the paper far from the paper outlet can hit the surface of the paper supporting plate before it completely falls down. The contact angle between the side of the paper far from the paper outlet and the paper supporting surface is small, thereby reducing the impact angle between the paper and the paper supporting surface, reducing the counterforce between the side of the paper and the paper discharge force, and reducing the probability of paper jamming in the printer. The distance between the paper supporting surface and the paper outlet gradually decreases in the vertical direction from the direction close to the paper outlet to the direction far from the paper outlet, and the paper supporting surface is arranged in an arc shape. The contact angle between the side of the paper far from the paper outlet and the paper supporting surface is further reduced, the impact force between the paper and the paper supporting surface is further reduced, the probability of paper jamming in the printer is further reduced, and the small contact angle can also prevent the impact between the paper and the paper supporting surface from causing creases or wear on the side of the paper.

[0010] In an optional embodiment, the paper supporting plate comprises:

[0011] a bottom plate, which is installed in the paper supporting groove;

[0012] a plurality of support rib groups, which are arranged on the bottom plate to support the printing paper.

[0019] Beneficial effects: The two support ribs in the support rib group can support the two sides of the corresponding paper pattern, while the several support ribs in the middle can provide auxiliary support for the middle part of the largest paper pattern, preventing the middle from collapsing due to the softness of the paper pattern.

[0020] In one optional embodiment, a first limiting rib is provided on the top surface of the paper tray along the paper discharge direction;

[0021] The bottom plate is provided with a second limiting rib on the side away from the supporting rib group, corresponding to the first limiting rib;

[0022] When the paper tray is placed in the paper tray groove, the first limiting rib is attached to the first limiting rib to restrict the degree of freedom of the paper tray.

[0023] Beneficial effects: When the paper tray is placed in the paper tray groove, the two second limiting ribs on the left side of the base plate are attached to the left side of the corresponding first limiting rib, and the two second limiting ribs on the right side of the base plate are attached to the right side of the corresponding first limiting rib, thereby limiting the paper tray in the left and right directions and improving its stability in the paper tray groove.

[0024] In one alternative implementation, all corners of the paper tray are chamfered.

[0025] Beneficial effect: Reduces the risk of the paper tray scratching the paper.

[0026] In one alternative embodiment, the base plate and the supporting rib assembly are integrally formed.

[0027] Beneficial effect: Improves the overall structural strength of the paper tray.

[0028] Secondly, the present invention also provides a printing system, including: the above-mentioned printing device;

[0029] The printer body is also equipped with an adjustable paper tray.

[0030] Beneficial effects: The adjustable paper tray can hold different paper sizes, automatically switching between different paper types during printing, saving manual adjustment time and allowing printing jobs to be completed more quickly, thus improving printing efficiency. Furthermore, the adjustable paper tray always keeps the paper in optimal printing-ready condition, preventing quality defects such as blurry text and incomplete images caused by paper skew or poor feed, ensuring consistently high-quality printouts that meet user requirements.

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0042] The file processing device includes a printer, a copier, a scanner and an email gateway. With the increasing demand for printing, the function of the printer is gradually enriched, and the speed and quality are greatly improved. In the double-sided printing function, the most important problem to be solved is the design of the reverse paper path, and the cooperation between the tray and the paper winding wheel is particularly important.

[0043] However, the related printer paper outlet 11 is deep, and the paper supporting surface 23 is an inclined plane, so the printer is not only suitable for printing ordinary paper 3, but also for printing books such as booklets with covers. The booklet generally contains multiple pages, and the outermost page is usually a higher gram weight paper product. When printing, the printer generally discharges the printed paper in an upwardly inclined direction, and the outermost page will be deformed due to the high temperature. Under the action of gravity, the side of the outermost page away from the paper outlet 11 will be more downwardly inclined. When the higher gram weight paper product away from the paper outlet 11 falls on the paper supporting surface 23, the contact angle between the paper product and the paper outlet 11 is too large, the impact force and direction are counteracted by the paper discharge force, and the probability of paper jamming of the printer is greatly increased.

[0044] To solve the above technical problems, the embodiment provides a printing device.

[0045] The embodiment of the present application is described below. Figures 1 to 5 The embodiment of the present application is described below.

[0046] According to the embodiment of the present application, on the one hand, a printing device is provided, as shown in Figure 1 The printing device comprises a printer body 1 and a paper supporting disc 2. The printer body 1 is provided with a paper outlet 11, and the paper outlet 11 is provided with a paper supporting groove 12 opposite the position. The depth of the paper supporting groove 12 gradually increases from the side away from the paper outlet 11 to the side close to the paper outlet 11. The paper supporting disc 2 is detachably installed in the paper supporting groove 12. The paper supporting disc 2 has a certain thickness, and the top surface of the paper supporting disc 2 close to the paper outlet 11 is a paper supporting surface 23. Any point on the paper supporting surface 23 is closer to the paper outlet 11 than the corresponding point directly below on the surface of the paper supporting groove 12. Compared with the prior art, when the paper is discharged from the paper outlet 11, the paper supporting surface 23 on the paper supporting disc 2 is higher than the top surface of the paper supporting groove 12. The paper supporting surface 23 can be in contact with the discharged paper 3 earlier than the paper supporting groove 12, so that the paper 3 with a higher gram weight collides with the surface of the paper supporting disc 2 before the side away from the paper outlet 11 completely falls. The contact angle between the side of the paper 3 away from the paper outlet 11 and the paper supporting surface 23 is small, and the contact angle between the side of the paper 3 away from the paper outlet 11 and the paper supporting surface 23 is Figure 2The angle θ is an angle between a tangent line of a side of the paper 3 far away from the paper outlet 11 and a tangent line of a contact point between the paper 3 and the paper supporting surface 23 when the side of the paper 3 far away from the paper outlet 11 contacts the paper supporting surface 23. The angle θ can reduce an impact angle between the paper 3 and the paper supporting surface 23, and reduce a counterforce between the paper 3 and the paper supporting surface 23, and reduce a probability of paper jamming of the printer. The distance between the paper supporting surface 23 and the paper outlet 11 in the vertical direction gradually decreases from a direction close to the paper outlet 11 to a direction far away from the paper outlet 11, and the paper supporting surface 23 is arranged as an arc shape protruding upward, which further reduces the contact angle between the side of the paper 3 far away from the paper outlet 11 and the paper supporting surface 23, further reduces the impact force between the paper 3 and the paper supporting surface 23, and reduces the probability of paper jamming of the printer. The small contact angle can also prevent the paper 3 from being jammed or the side of the paper 3 from being creased and abraded due to the impact between the paper 3 and the paper supporting surface 23.

[0047] As shown in Figure 3 and Figure 5 , the paper supporting disc 2 comprises a bottom plate 21 and a plurality of support ribs 22. The bottom surface of the bottom plate 21 is adapted to the upper surface of the paper outlet groove. The paper supporting disc 2 is stably installed in the paper outlet groove by the self-weight of the paper supporting disc 2, so as to smoothly discharge different paper types when the printer discharges paper. The plurality of support ribs 22 are arranged on the upper surface of the bottom plate 21. Each of the plurality of support ribs 22 comprises two support ribs 22. The two support ribs 22 in each of the plurality of support ribs 22 are symmetrically fixed on the bottom plate 21 with respect to the symmetry axis of the bottom plate 21 in the paper discharge direction. The distance between the outer surfaces of the two support ribs 22 in any two of the plurality of support ribs 22 is different to support different paper types.

[0048] In an embodiment, the two opposite support ribs 22 far away from the symmetry axis of the bottom plate 21 correspond to the maximum paper type that the printer body 1 can print. The distance between the outer sides of the two support ribs 22 in the support rib group far away from the symmetry axis of the bottom plate 21 is less than the width of the maximum paper type that the printer body 1 can print, and the difference between them is 5-10 mm. Figure 4 As shown in Figure 4 , for example, the maximum paper type that the printer can print is A4 paper, and the width of the A4 paper is 210 mm. The distance between the two support ribs 22 in the support rib group far away from the symmetry axis of the bottom plate 21 is selected to be between 200 mm and 205 mm to support the two sides of the maximum paper type. The middle plurality of support ribs 22 can assist in supporting the middle part of the maximum paper type to prevent the middle part from collapsing due to the softness of the paper type.As shown, the spacing between the outer surfaces of the two opposite support ribs 22 along the direction from inside to outside is A1, A2, A3, A4, A5, A6, A7, A8, A9 and A10 respectively. A1 = 17.0 mm; A2 = 60.0; A3 = 108.0 mm; A4 = 126.0 mm; A5 = 146.0 mm; A6 = 156.0 mm; A7 = 166.0 mm; A8 = 180.0 mm; A9 = 198.0 mm; A10 = 203.0 mm.

[0049] In one embodiment, the top surface of the paper supporting groove 12 is provided with first limiting ribs 13 along the paper discharging direction. Four first limiting ribs 13 are symmetrically arranged on both sides of the symmetric axis of the bottom plate 21, and two first limiting ribs 13 are arranged on each side of the symmetric axis of the bottom plate 21. Four second limiting ribs 24 are arranged on the side of the bottom plate 21 away from the group of support ribs 22, corresponding to the four first limiting ribs 13, as shown in Figure 1 and Figure 5 As shown, the two second limiting ribs 24 on the left side of the symmetric axis of the bottom plate 21 are arranged on the left side of the corresponding first limiting rib 13, and the two second limiting ribs 24 on the right side of the symmetric axis of the bottom plate 21 are arranged on the right side of the corresponding first limiting rib 13. When the paper supporting disc 2 is placed in the paper supporting groove 12, the two second limiting ribs 24 on the left side of the bottom plate 21 are fitted on the left side of the corresponding first limiting rib 13, and the two second limiting ribs 24 on the right side of the bottom plate 21 are fitted on the right side of the corresponding first limiting rib 13, thereby limiting the paper supporting disc 2 in the left-right direction and improving its stability in the paper supporting groove 12.

[0050] In one embodiment, the corners of the paper supporting disc 2 are chamfered to reduce the risk of scratching the paper 3. The bottom plate 21 and the group of support ribs 22 in the paper supporting disc 2 are integrally formed, which has high structural strength.

[0051] Specifically, the paper supporting disc 2 is provided with multiple sizes, including the width that can adapt to different sizes of the paper supporting groove 12, the height of the support rib 22 and the arc of the paper supporting surface 23 on the support rib 22. When the paper supporting disc 2 is installed in the paper supporting groove 12, after the paper 3 is discharged obliquely upward from the paper discharging port 11, the side of the paper 3 away from the paper discharging port 11 falls in a region between the tangent of the right-side arc of the paper supporting surface 23 and the horizontal line, and the included angle between the tangent and the tangent of the contact point of the paper supporting surface 23 and the paper 3 is less than 45 degrees. Preferably, it is 35 degrees.
