Abstract
Description
Technical Field
[0001] This utility model relates to the field of document printing equipment technology, specifically an improved document box printer. Background Technology
[0002] The printing of file boxes is usually done by a file box printer. A typical file box printer consists of a printer body and feed and output paperboards on the front and back sides. The printer body is equipped with dedicated software, which allows operators to intuitively edit the printing content, making printing simpler. The file box can enter the printer body from the feed paperboard to complete the printing work and be transported out from the output paperboard. In order to accommodate the printing of large-sized file boxes, an extension plate is usually set on the front side of the feed paperboard.
[0003] However, in the aforementioned file box printers, the extension plate is usually bolted to the feed plate, which makes the extension plate take up a lot of space and inconvenient to operate when printing file boxes of intermediate size. Furthermore, when printing small-sized file boxes, the extension plate needs to be removed to improve space utilization, and it is very easy to lose the extension plate if it is not used for a long time. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model provides an improved file box printer.
[0005] The technical solution of this utility model is as follows:
[0006] An improved file box printer includes a printer body and a feed plate on its front side. An extension plate is also provided on the front side of the feed plate. The printer body is used to print file boxes. The file boxes enter the printer body through the feed plate from the extension plate for printing. The extension plate is used to support the printing of large-sized file boxes.
[0007] As the core technical concept of this utility model, the front side of the feed paperboard is provided with an insertion port, and an extension plate is slidably provided in the insertion port. This file box printer also includes a fixing bolt. An elongated hole is opened on the extension plate. The fixing bolt is set vertically through the feed paperboard and the elongated hole, and a fixing nut is connected to the lower end. A clamping component is provided between the upper end and the extension plate. The cooperation between the elongated hole and the fixing bolt also plays a guiding role in adjusting the extension plate. The extension length of the extension plate is adjustable, and the extension plate can be fixed by the clamping component.
[0008] When using it, first loosen the fixing bolts, then push the extension plate to adjust its extension length, and then turn the fixing bolts in the opposite direction to press the clamping parts to tighten the extension plate. This allows the extension plate to be retracted into the cardboard while printing various sizes of file boxes, without having to remove the file box. This avoids the loss of the extension plate when printing small file boxes for a long time and improves the convenience of use.
[0009] Meanwhile, through the coordinated arrangement of the feed paper, extension plate, clamping component, fixing bolt, and fixing nut, the extension plate is fixed while avoiding the risk of defects such as pits caused by the fixing bolt directly acting on the upper surface of the feed paper, thus ensuring normal paper feeding. At the same time, since the fixing bolt penetrates the upper and lower sides of the feed paper and a fixing nut is provided on the lower side of the feed paper, even if the extension plate is pushed to the front of the feed paper, the extension plate will not easily come out of the slot, ensuring the safety of use.
[0010] Furthermore, the fixing bolt includes a screw and a bolt head at its upper end, and the clamping element is a cylindrical structure sleeved on the upper outer ring of the screw.
[0011] Specifically, the upper side of the cardboard insert has a through hole for the clamping component to pass through, and the lower side has a threaded hole for the screw to connect with it. During installation, the lower end of the screw of the fixing bolt passes vertically through the clamping component, the through hole on the upper side of the cardboard insert, and the elongated hole of the extension plate in sequence, and then connects with the threaded hole on the lower side of the cardboard insert and the fixing nut in sequence. At this time, the upper and lower ends of the clamping component abut against the lower end of the bolt head and the cardboard insert, respectively, thereby completing the fixing of the extension plate. When printing file boxes of different sizes, the extension plate can be adjusted by turning the fixing bolt to release the lower end face of the clamping component from the clamping state of the extension plate.
[0012] For ease of operation, the upper side of the clamping part is higher than the feed paperboard so that the bolt head of the fixing bolt is exposed on the upper side of the feed paperboard, making it easier to tighten the fixing bolt.
[0013] As one implementation method, the elongated hole is a countersunk hole with a waist shape. The lower end of the clamping component matches the countersunk part of the waist-shaped countersunk hole to improve the clamping effect.
[0014] Furthermore, a sliding groove is provided on the feed paperboard, and a sliding strip is provided on the extension plate corresponding to the sliding groove to slide and cooperate with it, so as to further improve the stability of the sliding cooperation between the extension plate and the feed paperboard.
[0015] Preferably, the sliding strip is located on the lower side of the extension plate, and the sliding groove is connected to the insertion port.
[0016] As one implementation method, there are two elongated holes, located on both sides of the sliding direction of the extension plate.
[0017] For ease of use, the upper and lower sides of the front center of the extension board are provided with curved grip areas, which are also provided with anti-slip textures.
[0018] For ease of processing, the cross-sectional shape of the sliding groove is rectangular, and the cross-sectional shape of the spigot is rectangular.
[0019] The beneficial effect of this improved file box printer is that, through the sliding cooperation between the extension plate and the feed plate, and through the detailed structural design of the two and the connection with the fixing bolts, not only can the extension length of the extension plate be adjusted to adapt to file boxes of different sizes, but it can also be retracted into the feed plate. When printing small-sized file boxes for a long time, it does not need to be removed, reducing the probability of loss and making it more convenient to use. Attached Figure Description

[0028] Combination Figure 2 An improved file box printer includes a printer body 1 and a feed plate 2 on its front side. An extension plate 3 is also provided on the front side of the feed plate 2. The printer body 1 is used to print file boxes. The file boxes enter the printer body 1 through the feed plate 2 and the extension plate 3 for printing. The extension plate 3 is used to support the printing of large-sized file boxes. The connection structure between the printer body 11 and the feed plate 22 is existing technology (e.g., ...). Figure 1 (This will not be elaborated upon here.)
[0029] Combination Figure 3As the core technical concept of this utility model, the front side of the feed paperboard 2 is provided with an insertion port 21, and an extension plate 3 is slidably provided in the insertion port 21. This file box printer also includes a fixing bolt 4. The extension plate 3 is provided with an elongated hole 31. The fixing bolt 4 is set vertically through the feed paperboard 2 and the elongated hole 31, and a fixing nut 6 is connected to the lower end. A clamping member 5 is provided between the upper end and the extension plate 3. The cooperation between the elongated hole 31 and the fixing bolt 4 also plays a guiding role for the extension plate 3. The extension length of the extension plate 3 is adjustable, and the extension plate 3 can be fixed by the clamping member 5.
[0030] In use, first loosen the fixing bolt 4, then push the extension plate 3 to adjust its extension length, and then twist the fixing bolt 4 in the opposite direction to make the clamping part 5 press the extension plate 3. This allows the extension plate 3 to be retracted into the cardboard 2 while printing various sizes of file boxes, without having to remove the file box. This avoids the loss of the extension plate 3 when printing small file boxes for a long time, and improves the convenience of use.
[0031] Meanwhile, through the coordinated arrangement of the feed plate 2, extension plate 3, clamping member 5, fixing bolt 4 and fixing nut 6, the extension plate 3 is fixed while avoiding the risk of defects such as pits caused by the fixing bolt 4 directly acting on the upper surface of the feed plate 2, thus ensuring normal paper feeding on the upper surface of the feed plate 2. At the same time, since the fixing bolt 4 penetrates the upper and lower sides of the feed plate 2 and the fixing nut 6 is also provided on the lower side of the feed plate 2, even if the extension plate 3 is pushed to the front end of the feed plate 2, the extension plate 3 will not easily come out of the insertion port 21, thus ensuring the safety of use.
[0032] Combination Figure 4 The fixing bolt 4 includes a screw 41 and a bolt head 42 at its upper end, and the clamping member 5 is a cylindrical structure sleeved on the upper outer ring of the screw 41.
[0033] Specifically, the upper side of the insert 21 of the paperboard 2 has a through hole for the clamping member 5 to pass through, and the lower side has a threaded hole for the screw 41 to be threaded and connected to it. During installation, the lower end of the screw 41 of the fixing bolt 4 passes vertically through the clamping member 5, the through hole on the upper side of the paperboard 2 and the elongated hole 31 of the extension plate 3 in sequence, and then threadedly connects downward to the threaded hole on the lower side of the paperboard 2 and the fixing nut 6 in sequence. At this time, the upper end and the lower end of the clamping member 5 abut against the lower end of the bolt head 42 and the paperboard 2 respectively, thereby completing the fixing of the extension plate 3. When printing file boxes of different specifications, the extension plate 3 can be adjusted by turning the fixing bolt 4 to release the lower end face of the clamping member 5 from the clamping state of the extension plate 3.
[0034] The upper side of the clamping member 5 is higher than the feed plate 2 so that the bolt head 42 of the fixing bolt 4 is exposed on the upper side of the feed plate 2, making it easier to tighten the fixing bolt 4.
[0035] Combination Figure 2 and Figure 3 To improve the clamping effect of the clamping member 5, the elongated hole 31 is a waist-shaped countersunk hole. The lower end of the clamping member 5 is matched with the countersunk part of the waist-shaped countersunk hole. The elongated hole 31 has two holes, which are located on both sides of the sliding direction of the extension plate 3.
[0036] Combination Figure 2 The extension plate 3 is provided with an arc-shaped hand grip area 33 on the upper and lower sides of the front middle section, and it is also provided with anti-slip texture, so that the operator can hold the arc-shaped hand grip area 33 to push the extension plate 3.
[0037] Combination Figure 3 and Figure 5 The feed plate 2 is also provided with a sliding groove 22, and the extension plate 3 is provided with a sliding strip 32 corresponding to the sliding groove 22 to slide and cooperate with it, so as to further improve the stability of the sliding cooperation between the extension plate 3 and the feed plate 2. The sliding strip 32 is located on the lower side of the extension plate 3, and the sliding groove 22 is connected to the insertion port 21.
[0038] For ease of processing, the cross-sectional shape of the sliding groove 22 is rectangular, and the cross-sectional shape of the socket 21 is rectangular.
