Abstract
Description
Technical Field
[0001] This utility model relates to the field of inkjet printing machine structure technology, and more specifically, to a printing machine printhead lifting device. Background Technology
[0002] An inkjet printer is a device that uses inkjet printing technology to print on textiles or other materials. It is widely used in clothing, home furnishings, advertising materials and other fields, and has the advantages of high efficiency, flexibility and environmental friendliness.
[0003] Inkjet printers spray ink into a substrate in the form of tiny droplets through a printhead. The printhead typically consists of multiple nozzles, each capable of precisely controlling the ink volume and position. The substrate (such as fabric or paper) moves within the machine via a conveyor belt or roller system, ensuring the ink is evenly distributed in the desired location. In existing technology, inkjet printers use a slide rail on the conveyor mechanism to connect the printhead and the substrate, with a slider on the machine body that engages with the slide rail. This allows the machine body to be extended to the side of the conveyor mechanism for maintenance.
[0004] In this structure, the minimum distance between the machine body and the conveying mechanism that carries the substrate is the distance between the printhead and the carrier component. This distance cannot be adjusted. When printing on different substrates, the thickness of the substrates also varies, resulting in different optimal printing distances. When printing on substrates of different thicknesses and specifications, the machine body needs to be replaced to adjust the printing distance, which is inconvenient to use. Utility Model Content

[0031] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0032] See Figure 1 , Figure 2 The printing machine nozzle lifting device provided in this embodiment includes a bracket assembly 100, a machine body 200, and a displacement mechanism 300.
[0033] The support assembly 100 includes a support frame 110 and a mounting frame 120. The support frame 110 supports the mounting frame 120, the machine body 200, and the displacement mechanism 300. The mounting frame 120 is located on the support frame 110 and has an installation space within it. The machine body 200 is located within the installation space and includes an inkjet assembly with its nozzles facing downwards. The displacement mechanism 300 includes a lifting assembly located on the mounting frame 120, and its moving end is connected to the machine body 200 via a transmission connection.
[0034] Specifically, in this embodiment, the mounting frame 120 is mounted on the support frame, and the machine body 200 is mounted on the mounting frame 120 via a lifting assembly, so that the machine body 200 can move vertically relative to the support frame 110 and the mounting frame 120, thereby adjusting the height of the nozzle.
[0035] During inkjet printing, if there are protrusions or wrinkles on the substrate surface, these can be avoided by raising the nozzle height, preventing the inkjet assembly from being scratched or bumped, thus avoiding damage. Furthermore, when inkjet printing on substrates of different thicknesses, the nozzle height can be adjusted using the lifting assembly to adapt to different substrate thicknesses, eliminating the need to replace the entire machine body, making it very convenient to use.
[0036] In this embodiment, the mounting bracket 120 is a mounting groove with its opening facing downwards, forming an installation space within the mounting groove. The lifting assembly includes a drive motor 310 and a transmission screw 320. The drive motor 310 is mounted on the mounting bracket 120, and the transmission screw 320 includes a rotating part and a moving part. The rotating part is vertically positioned within the mounting groove and is connected to the drive motor 310. The moving part is located on the rotating part and threadedly engages with it, and is connected to the machine body 200.
[0037] Specifically, in this embodiment, the body 200 is disposed in the mounting slot, which surrounds the body 200, thus protecting the body 200 and preventing it from colliding with external objects. In this embodiment, the height of the body 200 is adjusted by driving the transmission screw 320 through the drive motor 310. The drive motor 310 is connected to the rotating part to drive the rotating part to rotate. During the rotation of the rotating part, the moving part moves along the direction in which the rotating part is set, thereby achieving the height adjustment of the body 200.
[0038] In this embodiment, the lifting assembly further includes a drive shaft 330. There are two drive screws 320. The two drive screws 320 are respectively disposed on the inner walls of both ends of the mounting groove, and the two drive screws 320 are positioned opposite each other. The drive shaft 330 is drive-connected to the drive end of the drive motor 310, and the drive shaft 330 is drive-connected to the two drive screws 320 respectively.
[0039] In this embodiment, the two transmission screws 320 are respectively set on the two opposite inner walls of the mounting groove, thereby realizing the two-point connection and synchronous drive of the machine body 200. Both screws are connected to the drive end of the drive motor 310 through the transmission shaft 330, so that the drive motor 310 can synchronously drive the two transmission screws 320 through one transmission shaft 330, further ensuring the stability of the height adjustment of the machine body 200.
[0040] Specifically, in this embodiment, the drive motor 310 is mounted on the mounting bracket 120 and located outside the mounting space. The drive motor 310 and the two transmission screws 320 are located on the same straight line. The mounting bracket 120 is provided with a shaft hole, one end of the transmission shaft 330 passes through the shaft hole and is connected to the drive end of the drive motor 310, and the other end passes through the mounting space and is connected to the two transmission screws 320 for transmission.
[0041] In this embodiment, the drive motor 310 is located on the outer wall of the mounting slot to avoid occupying installation space, thereby reducing the volume of the mounting bracket 120. Specifically, the drive motor 310 is arranged horizontally outside the mounting slot, and one end of the transmission shaft 330 passes through the shaft hole in the side wall of the mounting slot to connect with the output end of the drive motor 310, so that the drive motor 310 can drive the transmission shaft 330 to rotate, thereby driving the two transmission screws 320 to rotate.
[0042] Furthermore, in this embodiment, a bushing 340 is provided on the top of the mounting bracket 120. The drive shaft 330 passes through the bushing 340 and slides in cooperation with the bushing 340.
[0043] Specifically, in this embodiment, the bushing 340 is disposed in the shaft hole. The bushing 340 has good lubrication performance, which can reduce the friction between the shaft and the hole, reduce the friction and wear between the drive shaft 330 and the shaft hole, and protect the drive shaft 330 and the shaft hole from damage.
[0044] As one feasible approach, there are multiple drive motors 310 and transmission screws 320. The multiple drive motors 310 are spaced apart in the mounting slots, and multiple lifting components and the machine body 200 are respectively connected by transmission.
[0045] When dealing with a larger body 200, which is heavier, multiple drive motors 310, transmission screws 320, and transmission shafts 330 can be set to form multiple lifting components, which together drive the body 200 to lift.
[0046] In this embodiment, the bracket assembly 100 further includes a guide member 130. A guide portion is provided on the body 200. The guide member 130 is disposed on the inner wall of the mounting groove, and is vertically arranged and connected to the guide portion.
[0047] The guide component 130, in conjunction with the guide part, can guide the movement of the machine body 200, preventing the transmission screw 320 from shaking during movement due to the excessive weight of the machine body 200 when the machine body 200 is too heavy, thus affecting the structural stability.
[0048] In this embodiment, the guide member 130 is a slider. The guide part is a groove, and the slider is inserted into the groove and slides in cooperation with the groove.
[0049] Combination Figure 2 Specifically, in this embodiment, the guide 130 is a slider, which is disposed on the inner wall of the mounting groove. Multiple sliders are symmetrically arranged on two opposite inner walls of the mounting groove to ensure stable movement of the machine body 200.
[0050] In this embodiment, the mounting groove wall is provided with weight reduction holes 121.
[0051] The weight reduction hole 121 can reduce the weight of the mounting bracket 120 and prevent the mounting bracket 120 from being too heavy, which would cause the support bracket 110 to bear too much weight.
[0052] In this embodiment, the displacement mechanism 300 further includes a lateral movement assembly. The support frame 110 has a horizontally extending beam 111. The lateral movement assembly is disposed on the beam 111, and the moving end of the lateral movement assembly is kinetically connected to the mounting frame 120.
[0053] Specifically, since the machine body 200 is located inside the mounting frame 120 in this embodiment, when maintaining and inspecting the machine body 200, it is necessary to move the machine body 200 out of the mounting frame 120, but the machine body 200 is located above the conveying mechanism. Therefore, in this embodiment, a lateral movement component is used to drive the mounting frame 120 and the machine body 200 to move laterally. When maintenance and inspection of the machine body 200 are required, the mounting frame 120 and the machine body 200 can be driven to move laterally together out of the area above the transmission mechanism, so that there is sufficient space below the mounting frame 120 for maintenance and inspection of the machine body 200.
[0054] Furthermore, in this embodiment, during the printing process of the machine body 200, the state of the machine body 200 inside the mounting slot can also be observed through the weight reduction hole 121. When performing a small amount of maintenance work, it can be operated directly through the weight reduction hole 121, which is very convenient to use.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
