[0002] Currently, grading machines and other printing equipment are widely used to grade student assignments and exams, and generate learning analysis reports, helping teachers reduce their workload and increase efficiency, and enabling personalized teaching.

[0003] However, in practical applications, it has been found that student assignments often have varying degrees of wrinkles after writing, and the surface may have foreign matter such as correction fluid or correction tape adhering to it. In addition, the paper used to print student assignments is usually thinner and lighter than office paper (i.e., with a lower grammage), and the paper cannot maintain a stable posture during printing. These factors together cause paper jams to occur frequently when existing printing equipment is used for printing assignment grading. To improve this situation, a comprehensive and complex adjustment and modification of the printer's software and hardware is required, which is costly, time-consuming, and labor-intensive.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] The following is combined Figures 1-6 The printing guidance device and printing equipment provided by the utility model embodiments will be described in detail through specific implementation methods and application scenarios.

[0027] In the first aspect, such as Figure 1 , Figure 2 and Figure 6 As shown, this utility model embodiment provides a printing guide device 1, including: a base 11, a slide rail assembly 12, a paper feed roller 13, and a paper pressing assembly 14; The base 11 is configured to be located in the printing link of the printing body 2; The slide rail assembly 12 is disposed on the upper side of the base 11 and is used to guide the print head 100 to move left and right. The slide rail assembly 12 includes a first slide rail 121 and a second slide rail 122. Both the first slide rail 121 and the second slide rail 122 can be metal rails, such as stainless steel rails. The first slide rail 121 and the second slide rail 122 are spaced apart along the paper feeding direction. A paper inlet is formed between the first slide rail 121 and the base 11, and a paper outlet is formed between the second slide rail 122 and the base 11. The paper feed roller 13 is rotatably disposed on the first slide rail 121 and located on the side of the first slide rail 121 facing the paper inlet; for example, the paper feed roller 13 is disposed on the side of the first slide rail 121 facing the base 11. The paper pressing assembly 14 is disposed between the first slide rail 121 and the second slide rail 122. A paper feeding gap is formed between the paper pressing assembly 14 and the base 11. One end of the paper feeding gap is disposed opposite to the paper inlet, and the other end is disposed opposite to the paper outlet.

[0028] It is understood that the paper feed direction of the paper to be printed 200 is the length direction of the paper to be printed 200. The first slide rail 121 and the second slide rail 122 corresponding to the slide rail assembly 12 are arranged side by side along the length direction of the paper to be printed 200. The first slide rail 121 and the second slide rail 122 form a moving range for the print head 100 to move left and right along the width direction of the paper to be printed 200. The first slide rail 121 and the second slide rail 122 both extend along the width direction of the paper to be printed 200. In this embodiment, the size of the paper to be printed 200 is not specifically limited.

[0029] For the paper pressing assembly 14, at least a portion of the paper pressing assembly 14 is disposed on the upper side of the base 11 to form a paper feeding gap between the paper pressing assembly 14 and the base 11. The width of the paper feeding gap should be greater than the thickness of the paper to be printed 200 to ensure that the paper to be printed 200 passes smoothly through the paper feeding gap.

[0030] The paper pressing assembly 14 can be made of metal or plastic, and there is no specific limitation on this. The setting of the paper pressing assembly 14 should not affect the normal movement of the print head 100, nor should it affect the printing operation of the print head 100 on the paper 200.

[0031] The printing guide device 1 shown in this utility model, by setting up a base 11, a slide rail assembly 12, a paper feed roller 13, and a paper pressing assembly 14, allows the paper feed roller 13 to contact the surface of the paper 200 and roll at a constant speed during the printing process. When the paper to be printed 200 enters the paper inlet between the first slide rail 121 and the base 11 through the printing link of the printing body 2, the paper feed roller 13 will roll at a constant speed to drive the paper 200 towards the paper outlet. During this process, the paper pressing assembly 14 can be used to control the paper 200 to be conveyed through the paper feed gap between the paper pressing assembly 14 and the base 11, so as to correct the posture of the conveyed paper 200 and limit the height of the paper 200 from the upward tilt caused by wrinkles to a certain extent. This ensures that the paper 200 is smoothly output from the paper outlet between the second slide rail 122 and the base 11, thereby significantly reducing the probability of paper jams and effectively solving the problem of frequent paper jams in existing printing equipment during batch printing.

[0032] In some embodiments, such as Figure 2 As shown, the gap width D1 of the paper feed gap is not greater than the gap width D2 of the paper outlet.

[0033] It is understandable that when the paper to be printed 200 is wrinkled, when the paper to be printed 200 is conveyed to the paper outlet under the drive of the paper feed roller 13, the head end of the paper to be printed 200 will roll and curl upward. If the height difference between the paper to be printed 200 and the paper outlet is too large, it will cause paper misalignment and paper jam.

[0034] Therefore, in this embodiment, by setting the gap width D1 of the paper feed gap to be no greater than the gap width D2 of the paper outlet, even if the head of the paper to be printed 200 is tilted upwards, the head of the paper will be ensured to smoothly enter the paper outlet during the feeding process, thereby reducing the probability of paper jams.

[0035] For example, D1 can be set to be greater than the thickness of the paper to be printed (200), and D1 can be equal to 25% to 100% of D2. For example, D1 can be equal to 25%, 50%, 75%, 100% of D2 or other suitable percentages, without specific limitations.

[0036] In some embodiments, such as Figure 1 , Figure 3 and 4 As shown, the paper pressing assembly 14 includes a first paper pressing member 141, which includes a first fixing part 1411, a pressing part 1412, and a second fixing part 1413. The first fixing part 1411 is connected to the first slide rail 121, the pressing part 1412 is disposed between the first slide rail 121 and the second slide rail 122, and forms a paper feeding gap with the base 11. The first end of the pressing part 1412 is connected to the first fixing part 1411; the second fixing part 1413 is connected to the second slide rail 122 and is connected to the second end of the pressing part 1412.

[0037] It is understandable that by configuring the first paper pressing component 141 as a first fixing part 1411, a pressing part 1412, and a second fixing part 1413, it is convenient to install and set the first paper pressing component 141 based on the first slide rail 121 and the second slide rail 122.

[0038] In practical applications, the first fixing part 1411 and the first slide rail 121 can be bonded together; and / or, the second fixing part 1413 and the second slide rail 122 can be bonded together. Of course, the first fixing part 1411 and the first slide rail 121 can also be detachably connected, as can the second fixing part 1413 and the second slide rail 122, without any specific limitation.

[0039] In order to facilitate control of the posture of the paper to be printed 200 during the conveying process, a pressing part 1412 can be provided to extend along the paper feeding direction of the paper to be printed 200, and the pressing part 1412 is arranged parallel to the upper side of the base 11.

[0040] In some embodiments, such as Figure 1 and Figure 4 As shown, the pressing part 1412 includes: a paper feed pressing head 14121, a pressing bar 14122, and a paper output pressing head 14123; The paper feed head 14121 is connected to the first fixing part 1411; the pressure bar 14122 is configured to extend along the paper feed direction and is located in the center line area of ​​the paper to be printed 200, and the first end of the pressure bar 14122 is connected to the paper feed head 14121 to form a "T" shaped structure; the paper output head 14123 is connected to the second fixing part 1413, and the second end of the pressure bar 14122 is connected to the paper output head 14123 to form a "T" shaped structure.

[0041] It is understandable that, considering that the content to be printed is usually distributed in the first and second areas on the paper to be printed 200, and the first and second areas are set on both sides of the center line area of ​​the paper to be printed 200, pressing the center line area of ​​the paper to be printed 200 by the pressure strip 14122 can press the paper to be printed 200 without affecting the printing operation of the print head 100 on the paper to be printed 200.

[0042] Meanwhile, since the paper feed head 14121 and the pressure bar 14122 form a "T" shape, and the pressure bar 14122 and the paper output head 14123 form a "T" shape, the paper feed head 14121 can control the pressing area of ​​the paper to be printed 200 when it enters the paper feed gap. During the conveying process within the paper feed gap, the pressure bar 14122, with its relatively small pressing area, mainly presses and controls the paper to be printed 200, and the paper feed head 14121 controls the paper to be printed 200 to maintain its conveying posture from the rear side along the conveying direction. When the paper to be printed 200 is output from the paper feed gap, the paper output head 14123 mainly controls the pressing area of ​​the paper to be printed 200. This design can effectively reduce the effective contact area between the holding part 1412 and the paper to be printed 200 while ensuring the pressing effect of the paper to be printed 200, thus achieving the effect of correcting and maintaining the conveying posture of the paper to be printed 200.

[0043] In some embodiments, such as Figure 2 As shown, a guide surface P is formed between the holding part 1412 and the first fixing part 1411. The guide surface P is disposed facing the paper inlet to guide the paper to be printed 200 input from the paper inlet into the paper feed gap.

[0044] It is understandable that, considering that the gap width of the paper feed opening is greater than the gap width of the paper feed gap, in order to ensure that the paper to be printed 200 smoothly enters the paper feed gap, a guide surface P needs to be provided between the holding part 1412 and the first fixing part 1411. The guide surface P can be an inclined surface or an arc surface, and there is no specific limitation on it.

[0045] In practical applications, driven by the paper feed roller 13, the paper to be printed 200 is conveyed from the paper inlet toward the paper feed gap. During this process, the leading end of the paper to be printed 200 will first contact the guide surface P, and under the guidance of the guide surface P, the leading end of the paper to be printed 200 will gradually move downward until it enters the paper feed gap.

[0046] In some embodiments, such as Figure 3 and Figure 4 As shown, at least one of the first fixing part 1411 and the second fixing part 1413 includes: a first folding plate 14111, a second folding plate 14112 and a third folding plate 14113; The first folding plate 14111 is disposed in the gap space between the first slide rail 121 and the second slide rail 122, and is connected to the pressing part 1412; the second folding plate 14112 is bent and connected to the first folding plate 14111, and is horizontally disposed on the top surface of the first slide rail 121 or the second slide rail 122; the third folding plate 14113 is bent and connected to the second folding plate 14112, and is used to hang in the groove on the first slide rail 121 or the second slide rail 122.

[0047] It is understandable that by setting the second folding plate 14112 and the first folding plate 14111 to be bent and connected, it is convenient to set the first folding plate 14111 in the gap space between the first slide rail 121 and the second slide rail 122, so as to realize the arrangement of the horizontally distributed pressing part 1412 based on the first folding plate 14111 in the gap space.

[0048] By setting the third fold plate 14113 and the second fold plate 14112 to be bent and connected, a hook structure can be formed based on the third fold plate 14113 and the second fold plate 14112, so that the third fold plate 14113 can be conveniently hung in the groove on the first slide rail 121 or the second slide rail 122, which serves to prevent the first paper pressing component 141 from moving relative to the slide rail assembly 12 along the width direction of the paper to be printed 200.

[0049] In practical applications, the first folding plate 14111 and the second folding plate 14112 can be set perpendicularly, and the second folding plate 14112 and the third folding plate 14113 can be set perpendicular to each other or parallel to the first folding plate 14111, without specific limitations. The first slide rail 121 or the second slide rail 122 is provided with multiple grooves for the third folding plate 14113 to be attached.

[0050] In some embodiments, such as Figure 2 and Figure 4 As shown, the first fixing part 1411 and the second fixing part 1413 have the same structure. Taking the first fixing part 1411 as an example, the first fixing part 1411 includes a first folding plate 14111, a second folding plate 14112 and a third folding plate 14113. The first folding plate 14111 of the first fixing part 1411 is located on the side of the first slide rail 121 facing the second slide rail 122, and the first folding plate 14111 of the second fixing part 1413 is located on the side of the second slide rail 122 facing the first slide rail 121. This design can prevent the first paper pressing part 141 from moving relative to the slide rail assembly 12 along the length direction of the paper to be printed 200.

[0051] In some embodiments, such as Figure 1 As shown, the paper pressing assembly 14 further includes two second paper pressing members 142, which are spaced apart from each other and disposed opposite to each other on both sides of the first paper pressing member 141. One of the second paper pressing members 142 is used to press one side of the paper to be printed 200, and the other second paper pressing member 142 is used to press the other side of the paper to be printed 200. The second paper pressing member 142 has the same structure as the first paper pressing member 141, and also includes the first fixing part 1411, the pressing part 1412 and the second fixing part 1413 shown in the above embodiment. The first fixing part 1411 of the second paper pressing member 142 is connected to the first slide rail 121, and the second fixing part 1413 of the second paper pressing member 142 is connected to the second slide rail 122.

[0052] It is understood that the paper feeding gap between the first paper pressing component 141 and the base 11 and the paper feeding gap between the second paper pressing component 142 and the base 11 can be the same or different, and no specific limitation is made in this regard.

[0053] In this embodiment, the two second paper pressing members 142 are used in conjunction with the first paper pressing member 141. While the first paper pressing member 141 presses the paper to be printed 200 along the center line area of ​​the paper to be printed 200, the two second paper pressing members 142 press the two sides of the paper to be printed 200 to ensure that the paper to be printed 200 maintains a flat posture during the conveying process and avoids the paper to be printed 200 from curling up due to wrinkles during the conveying process.

[0054] In some embodiments, such as Figure 3 and Figure 5 As shown, in order to ensure the pressing effect of the two second paper pressing parts 142 on both sides of the paper to be printed 200, and to be applicable to pressing the paper to be printed 200 with different widths, the width W1 of the pressing part 1412 of the second paper pressing part 142 can be set to be greater than the width W2 of the pressing part 1412 of the first paper pressing part 141 along the width direction of the paper to be printed 200. The width W1 of the pressing part 1412 of the second paper pressing part 142 is 5 to 20 mm, for example, the width W1 of the pressing part 1412 of the second paper pressing part 142 is 5 mm, 10 mm, 15 mm, 20 mm and other suitable width values.

[0055] In the second aspect, such as Figure 6 As shown, this utility model embodiment also provides a printing device, including: a printing body 2 and a printing guide device 1 as described above disposed on the printing body 2.

[0056] It is understood that the printing body 2 has a paper feed side 201 and a paper output side 202, and a printing link is formed between the paper feed side 201 and the paper output side 202 for conveying the paper to be printed 200 and printing the paper to be printed 200.

[0057] like Figure 1 and Figure 6 As shown, the paper feed side 201 can be located on the top of the printing body 2, the paper output side 202 can be located on the side of the printing body 2, and the printing guide device 1 is located inside the printing body 2 and is positioned opposite to the printing mechanism on which the print head 100 is located.

[0058] Since the printing device includes a printing guide device 1, and the specific structure of the printing guide device 1 is as described in the above embodiments, the printing device of this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiments, which will not be described in detail here.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
