Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and in particular to a color printing nozzle for a wall painting printing machine. Background Technology

[0002] In the field of contemporary architectural decoration and public art, wall printing presses are revolutionizing the paradigm of traditional wall art with their cutting-edge technology. This specialized printing equipment uses high-precision inkjet or transfer technology to directly replicate digital patterns on various wall surfaces, transforming design drafts into large-scale wall art.

[0003] In the prior art, for example, Chinese Patent No. CN218315909U discloses a color printing nozzle for a wall painting printing machine, including a base plate, a support frame fixed above the base plate, a drive screw mounted on the support frame, and a color painting spraying assembly mounted on the drive screw. The color painting spraying assembly includes an ink tank, a movable support plate, a pressure pump, a nozzle assembly, a cleaning assembly, and a spraying housing. The movable support plate is connected to the rear of the ink tank. In this wall painting printing machine, a conical connecting nozzle punctures the film at the bottom of the pigment bottle for spraying. This puncture-type installation prevents pigment leakage. When spraying different wall painting patterns, the pigment bottle is threaded, facilitating the replacement of different color pigment bottles. The entire nozzle assembly is detachable, facilitating nozzle replacement and cleaning, preventing internal blockage. A sealing ring is provided at the connection point to improve overall sealing efficiency, prevent pigment leakage, and clean the inside of the pipe to prevent pigment mixing, thus achieving the desired wall painting effect.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: although it can make the entire nozzle assembly detachable, facilitating nozzle replacement and cleaning and preventing internal blockage, it can only disassemble one nozzle at a time when rotating and disassembling the nozzle, which is time-consuming and labor-intensive, resulting in low nozzle disassembly efficiency. This, in turn, reduces the efficiency of the wall painting printing machine. Furthermore, it can only perform color printing on vertical walls and cannot perform color printing on top walls or inclined walls, thus reducing the applicability of the device. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing technologies. Although the entire nozzle assembly can be disassembled for easy replacement and cleaning, preventing internal blockage, the nozzles can only be disassembled one at a time when rotating them, which is time-consuming and laborious, resulting in low efficiency of nozzle disassembly and consequently reducing the efficiency of wall painting printing. Furthermore, these technologies can only print on vertical walls and cannot print on top or sloping walls, thus limiting the applicability of the device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a color printing head for a wall painting printing machine, comprising: a linear module two, and further comprising:

[0007] A nozzle assembly is disposed on one side of the linear module two. The nozzle assembly includes a nozzle seat. Multiple circular holes are equidistantly opened on one side of the nozzle seat. A nozzle is movably connected to the inside of the circular holes. Multiple sleeves are fixedly connected at equal intervals on the other side of the nozzle seat. The nozzle is threadedly connected to the sleeves. Sliding grooves are opened on opposite sides of the nozzle seat. Square frames are slidably connected to the inner walls of the two sliding grooves. Multiple circular rods are symmetrically fixedly connected at equal intervals on one side of the square frames. A rack is fixedly connected to one end of the two circular rods. Gears are fixedly connected to the outer surface of the nozzle. The multiple gears are evenly divided into multiple groups. The teeth of the multiple groups of gears mesh with the teeth of the multiple racks respectively. A connecting frame is rotatably connected to the outer surface of the multiple nozzles.

[0008] An adjustment mechanism is located on one side of the linear module two and is used to adjust the nozzle assembly.

[0009] Preferably, the nozzle assembly further includes a hose, which is fixedly connected to the sleeve, and the hose, sleeve, and nozzle are connected in communication. The ratio of the width of the gear to the width of the rack is 5:1.

[0010] Preferably, a fixing ring is fixedly connected to the inner wall of the sleeve, a rubber sealing ring is fixedly connected to one end of the nozzle, and a handle is fixedly connected to the other side of the frame.

[0011] Preferably, the bottom of the linear module two is provided with the linear module one, the moving block of the linear module one is fixedly connected to the linear module two, and the adjustment mechanism includes an L-shaped plate, which is fixedly connected to the moving block of the linear module two.

[0012] Preferably, a rotating rod is rotatably connected to one side of the L-shaped plate, and a motor is fixedly connected to the other side of the L-shaped plate, with the output end of the motor fixedly connected to one end of the rotating rod.

[0013] Preferably, the other end of the rotating rod is fixedly connected to a movable strip, and a slide bar is slidably connected inside the movable strip, the slide bar being fixedly connected to the nozzle seat.

[0014] Preferably, a fixing block one is fixedly connected to one side of the movable strip, an electric telescopic rod is fixedly connected to the top of the fixing block one, and a fixing block two is fixedly connected to one side of the slide bar, with the fixing block two being fixedly connected to the electric telescopic rod.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model allows the user to push the square frame to one side by holding the handle, causing it to slide along the inside of the groove. This simultaneously moves the round rod and rack to one side. The meshing of the rack and gear allows the gear to rotate the nozzle. The threaded connection between the nozzle and the sleeve allows the nozzle to rotate out of the sleeve, simultaneously moving it a suitable distance along the inside of the round hole. This also moves the connecting frame and gear a suitable distance. At this point, the teeth of the gear and rack slide against each other. When the nozzle detaches from the sleeve, multiple nozzles can be removed together through the connecting frame; conversely, they can be installed together. This allows for simultaneous disassembly or installation of multiple nozzles, saving time and effort and improving the efficiency of nozzle disassembly and installation, thereby increasing the efficiency of the wall painting printing machine.

[0017] 2. This utility model uses a controller to start a motor, causing its output shaft to drive a rotating rod to rotate, which in turn drives the movable bar, slide bar, and nozzle assembly to rotate. This causes the nozzle assembly to face upwards or maintain a certain tilt angle. The nozzle assembly is adjusted to a suitable height using linear module two, and moved left and right using linear module one. The controller then controls the electric telescopic rod to extend or retract, applying a pushing or pulling force to fixed block two. This simultaneously drives the slide bar to slide outwards or inwards along the inside of the movable bar, connecting the nozzle assembly to the pigment delivery equipment for color printing on the top wall surface. This allows for color printing not only on vertical walls but also on top and inclined walls, thus improving the applicability of the device. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Examples, such as Figure 1-4 As shown, this utility model provides a color printing head for a wall painting printing machine, including: a linear module 2, and a printhead assembly disposed on one side of the linear module 2. The printhead assembly includes a printhead base 4, on one side of the printhead base 4, a plurality of circular holes 412 are equidistantly opened, and a spray pipe 401 is movably connected inside the circular holes 412. On the other side of the printhead base 4, a plurality of sleeves 402 are fixedly connected at equal intervals, and the spray pipe 401 is threadedly connected to the sleeves 402. A sliding groove 404 is opened on each opposite side of the printhead base 4. A square frame 405 is slidably connected to the inner wall. Multiple round rods 407 are symmetrically and equidistantly fixed to one side of the square frame 405. A rack 408 is fixedly connected to one end of two round rods 407. A gear 409 is fixedly connected to the outer surface of the nozzle 401. The multiple gears 409 are evenly divided into multiple groups. The teeth of the multiple groups of gears 409 mesh with the teeth of the multiple racks 408 respectively. A connecting frame 413 is rotatably connected to the outer surface of the multiple nozzles 401. An adjustment mechanism is set on one side of the linear module 2 and is used to adjust the nozzle assembly.

[0027] Furthermore, such as Figure 1-4 As shown, the nozzle assembly also includes a hose 403, which is fixedly connected to the sleeve 402. The hose 403, sleeve 402 and nozzle 401 are connected. The width ratio of the gear 409 to the width of the rack 408 is 5:1. With the above configuration, the pigment conveying device can sequentially convey pigment to the hose 403, sleeve 402 and nozzle 401.

[0028] Furthermore, such as Figure 1-4 As shown, a retaining ring 411 is fixedly connected to the inner wall of the sleeve 402, a rubber sealing ring 410 is fixedly connected to one end of the nozzle 401, and a handle 406 is fixedly connected to the other side of the frame 405. With the cooperation of the rubber sealing ring 410 and the retaining ring 411, when the nozzle 401 is rotated into the sleeve 402, the rubber sealing ring 410 will be in close contact with the retaining ring 411, thus achieving a certain sealing effect.

[0029] Furthermore, such as Figure 1-4 As shown, linear module 1 is provided at the bottom of linear module 2. The moving block of linear module 1 is fixedly connected to linear module 2. The adjustment mechanism includes an L-shaped plate 3, which is fixedly connected to the moving block of linear module 2. By setting linear module 1, linear module 2, adjustment mechanism and nozzle assembly can be driven to move left and right. By setting linear module 2, adjustment mechanism and nozzle assembly can be driven to move up and down.

[0030] Furthermore, such as Figure 1-4 As shown, a rotating rod 301 is rotatably connected to one side of the L-shaped plate 3, and a motor 302 is fixedly connected to the other side of the L-shaped plate 3. The output end of the motor 302 is fixedly connected to one end of the rotating rod 301. The motor 302 is started by the controller, so that its output shaft drives the rotating rod 301 to rotate.

[0031] Furthermore, such as Figure 1-4 As shown, the other end of the rotating rod 301 is fixedly connected to a movable bar 303, and a slide bar 307 is slidably connected inside the movable bar 303. The slide bar 307 is fixedly connected to the nozzle seat 4. With the above arrangement, the slide bar 307 can slide inside the movable bar 303, and synchronously drive the nozzle seat 4 to move.

[0032] Furthermore, such as Figure 1-4 As shown, a fixing block 304 is fixedly connected to one side of the movable bar 303, and an electric telescopic rod 305 is fixedly connected to the top of the fixing block 304. A fixing block 306 is fixedly connected to one side of the slide bar 307. The fixing block 306 is fixedly connected to the electric telescopic rod 305. The electric telescopic rod 305 can be extended or retracted by controlling the controller, which can apply a pushing or pulling force to the fixing block 306, and simultaneously drive the slide bar 307 to slide outward or inward along the inside of the movable bar 303.

[0033] Working principle: When disassembling the nozzle 401, hold the handle 406 and push the square frame 405 to one side, causing it to slide along the inside of the groove 404. This simultaneously moves the round rod 407 and the rack 408 to one side. Then, with the meshing of the rack 408 and the gear 409, the gear 409 can drive the nozzle 401 to rotate. Subsequently, with the threaded connection between the nozzle 401 and the sleeve 402, the nozzle 401 can rotate out from inside the sleeve 402, simultaneously moving the nozzle 401 a suitable distance to one side along the inside of the round hole 412. The connecting frame 413 and gear 409 move a suitable distance synchronously. At this time, the teeth of gear 409 and rack 408 slide against each other. When the nozzle 401 disengages from the sleeve 402, multiple nozzles 401 can be removed collectively through the connecting frame 413. Conversely, they can be installed collectively. In this way, when it is necessary to disassemble or install the nozzles 401, multiple nozzles 401 can be disassembled or installed simultaneously, which saves time and effort, thereby improving the efficiency of nozzle disassembly and installation, and thus improving the efficiency of color printing of the wall painting printing machine. This is achieved through the linear module 1. The linear module 2 can be configured to drive the adjustment mechanism and nozzle assembly to move left and right. The linear module 2 can also be configured to drive the adjustment mechanism and nozzle assembly to move up and down. Linear modules 1 and 2 are existing technologies and will not be described in detail. When the nozzle assembly needs to paint on the top or inclined wall surface, the controller starts the motor 302, causing its output shaft to drive the rotating rod 301 to rotate, simultaneously driving the movable bar 303, slide bar 307, and nozzle assembly to rotate, making the nozzle assembly face upwards or maintain a certain tilt angle. Module 2 adjusts the nozzle assembly to a suitable height, and the linear module 1 adjusts the nozzle assembly to move left and right. Then, the controller controls the electric telescopic rod 305 to extend or retract, which can apply a pushing or pulling force to the fixed block 306. Simultaneously, it drives the slide bar 307 to slide outward or inward along the inside of the movable bar 303, and connects the nozzle assembly to the pigment delivery equipment to perform color printing on the top wall. This not only allows for color printing on vertical walls, but also on top walls and inclined walls, thereby improving the applicability of this device.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
