[0002] The print carriage of a digital printing device is used to perform inkjet printing on print media. The interior of the print carriage houses several nozzle assemblies, a control valve assembly, ink tubes for accessing ink, and other components. Therefore, the print carriage is provided with a front side panel that can be opened or closed to facilitate operator access to the internal components of the carriage, as well as repair and maintenance. Existing front side panels are typically hinged to the carriage at the top. This structure allows the front side panel to pivot and open around the connection when opened, exposing the internal structure of the carriage. This installation method leaves the front side panel suspended above the operator's head, creating a risk of it falling and striking the operator. Furthermore, the panel forms a certain angle with the main body of the carriage when opened, resulting in limited clearance and making it difficult for the operator to perform proper removal, repair, and maintenance of the carriage. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] See also Figures 1-2 The present invention provides a front cover mounting structure for a printing carriage, comprising a front cover 1 and a carriage body 2. The front cover 1 comprises side panels 11 and a top panel 12 disposed on top of the side panels 11. The top panel 12 is provided on top of the carriage body 2 with a mounting position 21 adapted to fit the top panel 12. The side panels 11 cover the front end of the carriage body 2, which is the front side of the carriage body when in operation. The top panel 12 is secured in place in the mounting position 21.

[0027] By setting the side panels 11 of the front cover 1 to cover the front end surface of the trolley body 2, and the top panel 12 of the front cover 1 to cooperate with the top mounting position 21 of the trolley body 2, the front cover 1 and the trolley body 2 can be detachably installed. When it is necessary to disassemble and maintain the components in the trolley body 2, the front cover 1 can be directly removed, which can avoid the risk of falling when the front cover 1 and the trolley body 2 are connected in a hinged manner. In addition, directly removing the front cover 1 can also maximize the exposure of the internal structure of the trolley body 2, which is convenient for the operator to disassemble, assemble and inspect and maintain. At the same time, only the top panel 12 is matched with the mounting position 21, which facilitates the removal and installation of the front cover 1. The disassembly and assembly are extremely simple. After the front cover 1 is removed, the front cover 1 can also be hung on other platforms through the top panel 12, including but not limited to the edge of the printing platform of digital equipment. The structural design is clever, which can avoid the phenomenon of messy placement after the front cover 1 is removed.

[0028] The printing carriage front cover installation structure provided by the present invention does not create the risk of the front cover 1 falling off when the internal components of the carriage body 2 are disassembled, assembled, inspected, and maintained. Opening or closing the interior of the carriage body 2 through the front cover 1 is extremely easy to operate.

[0029] Specifically, the front cover 1 can be made of transparent materials, including but not limited to acrylic plates, so that it is convenient to observe abnormal conditions inside the trolley body 2 when the trolley body 2 is working. At the same time, the transparent material is light in weight, which can reduce the burden when disassembling and assembling the front cover 1.

[0030] See also Figure 3 Specifically, a first positioning member 121 is provided on the side of the top plate 12 facing the vehicle body 2, and a first positioning groove 211 is provided on the mounting position 21 to match the first positioning member 121. When the top plate 12 is engaged with the mounting position 21, the first positioning member 121 is snapped into the first positioning groove 211. This ensures a secure fit between the top plate 12 and the mounting position 21, preventing the front cover 1 from falling off the vehicle body 2.

[0031] See also Figure 2 、 Figure 4 Furthermore, second positioning members 111 are provided on opposite sides of a side panel 11 facing the trolley body 2, and strip grooves 22 are provided on opposite sides of the front end surface of the trolley body 2. The strip grooves 22 extend in the vertical direction, and the second positioning members 111 cooperate with the strip grooves 22 and can move in the strip grooves 22. When the second positioning members 111 are inserted into the strip grooves 22, the front cover 1 moves downward, and the first positioning members 121 are snapped into the first positioning grooves 211. A second positioning piece 111 is provided on the side panel 11 facing the trolley body 2, and a strip groove 22 matching the second positioning piece 111 is provided on the trolley body 2. During installation, it is only necessary to align the second positioning piece 111 with the strip groove 22. At this time, the first positioning piece 121 is just above the first positioning groove 211. By moving the front cover 1 downward as a whole, the first positioning piece 121 can be accurately inserted into the first positioning groove 211. There is no need to deliberately make the first positioning piece 121 find the first positioning groove 211, which is convenient for the operator to install and makes the installation extremely fast. When removing the front cover 1, it is only necessary to move the front cover 1 upward as a whole to disengage the first positioning piece 121 from the first positioning groove 211 to remove the front cover 1. Disassembly is also extremely quick and easy.

[0032] See also Figure 4 Specifically, the first positioning member 121 is a plate-like structure, and the side and bottom edges of the first positioning member 121 are transitioned by arcuate surfaces 121a. Thus, even if there is a slight deviation between the first positioning member 121 and the first positioning groove 211, the arcuate surfaces 121a can help the first positioning member 121 slide smoothly into the first positioning groove 211, thereby improving the smoothness of the fit between the first positioning member 121 and the first positioning groove 211.

[0033] See also Figure 2 、 Figure 4 Furthermore, at least two second positioning members 111 are provided on one side, and the at least two second positioning members 111 are spaced apart in the vertical direction. The strip grooves 22 correspond one-to-one with the at least two second positioning members 111. Thus, as long as any corresponding set of second positioning members 111 engages with the strip grooves 22, the first positioning member 121 and the first positioning groove 211 are aligned, allowing the first positioning member 121 to quickly engage with the first positioning groove 211, further improving the efficiency of installing the front cover 1 and the trolley body 2.

[0034] In this embodiment, three second positioning members 111 are provided on each side, and three corresponding strip-shaped grooves 22 are also provided on the same side.

[0035] See also Figures 4-6Furthermore, the front cover 1 also includes a bottom plate 13 disposed at the bottom of the side plate 11. The bottom plate 13 includes a first plate 131 connected to the side plate 11 and a second plate 132 extending downward from the first plate 131. A second positioning groove 23 is provided on the inner side of the front end surface of the trolley body 2. When the side plate 11 covers the front end surface of the trolley body 2, the second plate 132 is inserted into the second positioning groove 23. This improves the structural tightness of the bottom of the side plate 11 of the front cover 1 and the front end surface of the trolley body 2, preventing a gap from forming between the bottom of the side plate 11 and the trolley body 2, which could cause debris to fall into the trolley body 2.

[0036] See also Figure 6 Furthermore, a slanted plate 133 is provided at the front end of the second plate 132 inserted into the second positioning groove 23. The slanted plate 133 is inclined from the second plate 132 in a direction away from the side plate 11. When the bottom plate 13 is inserted into the second positioning groove 23, the slanted plate 133 abuts against the notch wall of the second positioning groove 23 and is inserted into the second positioning groove 23. By providing the slanted plate 133, the slanted plate 133 can guide the bottom plate 13 when it is inserted into the second positioning groove 23. After the second positioning member 111 is engaged with the strip groove 22, when the first positioning member 121 is located above the first positioning groove 211, the slanted plate 133 abuts against the notch of the second positioning groove 23. When the front cover 1 moves downward, the slanted plate 133 drives the entire bottom plate 13 along the notch and into the second positioning groove 23. Therefore, there is no need to calibrate and position the bottom plate 13 and the second positioning groove 23. The installation and positioning steps of the entire front cover 1 are extremely simple and quick.

[0037] To sum up, when installing the entire front cover 1, it is only necessary to match the second positioning member 111 with the strip groove 22 and place the top plate 12 above the installation position 21. At this time, the first positioning member 121 is aligned with the first positioning groove 211 on the installation position 21, and the inclined plate 133 of the bottom plate 13 also abuts against the slot mouth wall of the second positioning groove 23. Put down the front cover 1, and the gravity of the front cover 1 causes it to move downward. The first positioning member 121 is stuck in the first positioning groove 211, and the inclined plate 133 of the bottom plate 13 drives the bottom plate 13 to slide into the second positioning groove 23. The installation of the front cover 1 is completed; when disassembling, lift the front cover 1 upward and then move it out horizontally to remove the front cover 1.

[0038] Figure 6 Furthermore, the second positioning groove 23 is the waste ink drain groove of the trolley body 2. Specifically, a waste ink drain groove is provided at a position near the front end side surface of the front end side surface of the trolley body 2. A plurality of ink drain joints 3 are provided on one side of the waste ink drain groove close to the inside of the trolley body 2. The ink drain joints 3 are used to connect with the nozzles one by one when repairing the nozzles, so that the ink in the nozzles is discharged into the waste ink cartridge through the ink drain joints 3. Therefore, the existing waste ink cartridge is reasonably used in conjunction with the bottom plate 13, which can avoid additional processing of the second positioning groove 23 and will not change the internal structure of the trolley body 2.

[0039] Furthermore, when the top plate 12 is matched with the mounting position 21, the surface of the top plate 12 is flush with the surface of the trolley body 2, so that the consistency of the external structure of the trolley body 2 can be maintained, avoiding damage to the external structure of the trolley body 2, making it more beautiful.

[0040] Furthermore, when the side panel 11 covers the front end face of the trolley body 2, the surface of the side panel 11 protrudes from the adjacent side face of the trolley body 2 and its front end face, and the specific protruding height is the thickness of the side panel 11. This makes it convenient for the operator to hold the front cover 1 from both sides of the side panel 11, facilitating the disassembly and assembly of the front cover 1.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
