[0034] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0035] See also Figures 1 to 4 The inkjet printing platform provided in this embodiment includes a platform body 100 and a plane detection mechanism 200 .

[0036] The platform body 100 has a guide belt 110 for holding and transporting printed materials, and the moving direction of the guide belt 110 is a first direction.

[0037] The plane detection mechanism 200 includes a transmitter 210, a reflector and an installation assembly 220. There are two installation assemblies 220, which are arranged on both sides of the guide belt 110 perpendicular to the first direction. The transmitter 210 and the reflector are arranged in a one-to-one correspondence with the two installation assemblies 220.

[0038] Specifically, the mounting assembly 220 in this embodiment includes a mounting plate 221, a connecting plate 222 and an adjusting member 223. The mounting plate 221 is spaced apart from the platform body 100. The side of the mounting plate 221 close to the platform body 100 is the mounting surface. The connecting plate 222 is disposed between the mounting plate 221 and the platform body 100 and is connected to the platform body 100. A launching port is provided on the connecting plate 222. Both ends of the adjusting member 223 are respectively connected to the mounting plate 221 and the connecting plate 222. The adjusting member 223 is used to adjust the distance between the mounting plate 221 and the connecting plate 222. There are multiple adjusting members 223, and the multiple adjusting members 223 are evenly arranged along the circumference of the mounting plate 221.

[0039] When transported by the guide belt 110 in this embodiment, the reflector and the emitter 210 are respectively arranged on both sides of the guide belt 110 through the mounting assembly 220, and the laser emitted by the emitter 210 is reflected back by the reflector. If the laser can be received normally, the surface of the guide belt 110 is flat.

[0040] Before detection, the distances corresponding to different positions of the mounting plate 221 and the connecting plate 222 are adjusted through the adjusting parts 223, thereby changing the inclination angle of the mounting plate 221, and further changing the orientation direction of the emitting part 210 or the reflecting part, thereby adjusting the orientation direction of the emitting part 210 and the reflecting part, so that the emitting part 210 and the reflecting part can accurately scan the top surface (i.e., the loading surface) of the guide belt 110, and the adjustment is very convenient.

[0041] In this embodiment, the mounting assembly 220 further includes an elastic reset member 230 . Two ends of the elastic reset member 230 are respectively in contact with the mounting plate 221 and the connecting plate 222 . The adjusting member 223 is inserted into the elastic reset member 230 .

[0042] The elastic reset member 230 is arranged between the mounting plate 221 and the connecting plate 222, and the elastic reset member 230 can push the mounting plate 221 and the connecting plate 222 to both sides. After the spacing between the mounting plate 221 and the connecting plate 222 is adjusted to a point where detection can be achieved by the adjusting member 223, the elastic reset member 230 pushes the mounting plate 221 and the connecting plate 222 until both reach the limit position. At this time, the outer sides of the mounting plate 221 and the connecting plate 222 are blocked by the adjusting member 223, so that the mounting plate 221 and the connecting plate 222 will not fall off the adjusting member 223, and the inner sides of the mounting plate 221 and the connecting plate 222 are pushed outward by the elastic reset member 230, so as to prevent the mounting plate 221 and the connecting plate 222 from sliding or moving on the adjusting member 223, causing the orientation angle of the transmitting member 210 or the reflecting member to change.

[0043] In this embodiment, the elastic reset member 230 is a compression spring, and the adjustment member 223 is a bolt. The two ends of the compression spring are respectively in contact with the mounting plate 221 and the connecting plate 222. The mounting plate 221 and the connecting plate 222 are provided with connecting holes at opposite positions. The bolt connects the mounting plate 221 and the connecting plate 222 through the connecting holes, and the end away from the nut is inserted into the connecting plate 222. The nut is located on the side of the mounting plate 221 away from the platform body 100.

[0044] The compression spring has excellent elasticity. After being slightly compressed, it is sleeved on the screw rod of the bolt, and can keep both ends in contact with the mounting plate 221 and the connecting plate 222 respectively, thereby ensuring that the relative position between the mounting plate 221 and the connecting plate 222 remains fixed.

[0045] Specifically, the nut of the bolt in this embodiment is pressed on the surface of the mounting plate 221. When installing, the end of the bolt away from the nut must first be inserted into the connection hole on the mounting plate 221, and then inserted into the compression spring and the connecting plate 222 in sequence, thereby achieving the connection between the bolt, the mounting plate 221, the compression spring and the connecting plate 222. The nut can press the mounting plate 221 from both sides with the compression spring. When adjusting the spacing between the mounting plate 221 and the connecting plate 222, the adjustment can be achieved by turning the bolt, which is convenient to operate and easy to maintain.

[0046] In this embodiment, a long hole is provided at one end of the connecting plate 222 away from the mounting plate 221. The long hole extends in the vertical direction and penetrates the connecting plate 222 in the horizontal direction, and the connecting plate 222 is connected to the platform body 100 through the long hole.

[0047] In this embodiment, the connecting plate 222 and the platform body 100 are detachably connected by means of screw locking, and the screws are passed through the long holes to lock the connecting plate 222 to the side of the platform body 100. When the height of the emitting element 210 or the reflecting element needs to be adjusted, the screws can be loosened and the connecting plate 222 can be moved vertically through the long holes, and the screws can be tightened again when the height is appropriate, which is very convenient for installation and adjustment.

[0048] In this embodiment, there are two long holes, which are parallel to each other and spaced apart in the horizontal direction.

[0049] Screws are inserted into the two long holes for locking. The two-point locking method is more stable and the connecting plate 222 is not easy to rotate after locking.

[0050] In this embodiment, the transmitting element 210 includes a laser signal transmitter, a signal amplifier and a signal receiver. The laser signal transmitter is connected with the signal amplifier and is disposed on the mounting plate 221. The signal receiver is disposed on the mounting plate 221.

[0051] Specifically, the laser signal transmitter in this embodiment can generate and emit a light curtain, and the light curtain is amplified by a signal amplifier to prevent the light curtain signal from being too weak to be received. The signal receiver can receive the light curtain, and when the signal reception is incomplete or missing, it is because the surface of the guide belt 110 is uneven.

[0052] In this embodiment, the reflective element and the emitting element 210 are arranged opposite to each other.

[0053] In this embodiment, after the signal reflecting element and the emitting element 210 are arranged relative to each other, the light curtain is reflected by the reflecting element to further increase the height of the light curtain. The receiver and the laser signal transmitter are arranged on the same side. The light curtain is received by the signal receiver after being reflected by the reflecting element. When the signal reception is incomplete or missing, it is because the surface of the guide belt 110 is uneven.

[0054] In this embodiment, the emission content of the emission element 210 is a light curtain with a height greater than or equal to 1 cm, and the bottom of the light curtain overlaps with the guide belt 110, and the overlapped portion of the light curtain with the guide belt 110 is less than or equal to 30% of the height of the light curtain.

[0055] Specifically, the height of the light curtain in this embodiment is one centimeter, and the width of the light curtain above the guide belt 110 is 70 millimeters. In the structure where part of the light curtain overlaps with the guide belt 110 (or the side of the platform), the remaining non-overlapping light curtain can ensure that it fits the upper surface of the guide belt 110, thereby ensuring the accuracy of detection.

[0056] In this embodiment, there are a plurality of plane detection mechanisms 200 , which are arranged at intervals along the conveying direction of the guide belt 110 .

[0057] After a plurality of plane detection mechanisms 200 are arranged at intervals along the conveying direction of the guide belt 110, multiple and multi-position detections of the guide belt 110 can be realized, thereby avoiding missed detection or wrong detection when a laser component is damaged.

[0058] See also Figure 5 The printing machine provided in this embodiment includes an inkjet printing platform.

[0059] The inkjet printing platform includes a platform body 100 and a plane detection mechanism 200. The platform body 100 has a guide belt 110 for holding and transporting printed materials, and the moving direction of the guide belt 110 is a first direction. The plane detection mechanism 200 includes an emitting element 210, a reflecting element, and a mounting assembly 220. There are two mounting assemblies 220, which are arranged on both sides of the guide belt 110 perpendicular to the first direction, and the emitting element 210 and the reflecting element are arranged one by one with the two mounting assemblies 220. Specifically, the mounting assembly 220 in this embodiment includes a mounting plate 221, a connecting plate 222 and an adjusting member 223. The mounting plate 221 is spaced apart from the platform body 100. The side of the mounting plate 221 close to the platform body 100 is the mounting surface. The connecting plate 222 is disposed between the mounting plate 221 and the platform body 100 and connected to the platform body 100. The connecting plate 222 is provided with an emission port. The two ends of the adjusting member 223 are respectively connected to the mounting plate 221 and the connecting plate 222. The adjusting member 223 is used to adjust the distance between the mounting plate 221 and the connecting plate 222. There are multiple adjusting members 223, and the multiple adjusting members 223 are evenly arranged along the circumference of the mounting plate 221. When transported by the guide belt 110 in this embodiment, the reflector and the emitting member 210 are respectively arranged on both sides of the guide belt 110 through the mounting assembly 220. The emitting member 210 emits laser light and reflects it back through the reflector. If the laser light can be received normally, the surface of the guide belt 110 is flat. Before detection, the distances corresponding to different positions of the mounting plate 221 and the connecting plate 222 are adjusted through the adjusting parts 223, thereby changing the inclination angle of the mounting plate 221, and further changing the orientation direction of the emitting part 210 or the reflecting part, thereby adjusting the orientation direction of the emitting part 210 and the reflecting part, so that the emitting part 210 and the reflecting part can accurately scan the top surface (i.e., the loading surface) of the guide belt 110, and the adjustment is very convenient.
