Description

Technical Field

[0001] This utility model relates to the field of digital printing equipment, and in particular to a digital printing precision alignment device. Background Technology

[0002] In the digital printing process, precise alignment between the printed pattern and the fabric is crucial. Currently, the alignment of fabrics for clothing and other textiles mostly relies on manual labor to precisely lay them flat on a material table. This process is time-consuming, inefficient, and prone to deviations, resulting in inaccurate printed pattern placement and affecting the product's aesthetics and quality. Furthermore, different batches of fabric may vary in size and shape, and traditional positioning methods cannot adapt to these changes, further reducing alignment accuracy. Therefore, a precise alignment device for digital printing is proposed to address these issues. Utility Model Content

[0003] The main purpose of this invention is to provide a digital printing precision alignment device to solve the problems of low efficiency and easy deviation in traditional positioning methods.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a digital printing precision alignment device, including a support platform, a circular conveyor line set on the support platform, and a digital printing machine. The digital printing machine includes two support frames set on the side of the support platform and on the central axis of the support platform. The tops of the two support frames are flush with each other and are equipped with a digital printing body that can move horizontally and vertically. The circular conveyor line passes under the digital printing body. Alignment material platforms are set on the conveyor platforms of the circular conveyor line. An image acquisition device is also set on the support platform in front of the digital printing machine. The image acquisition device is located directly above the alignment material platform that passes through it.

[0005] The alignment material platform includes a support platform set on the conveyor platform and extending forward, a cross displacement mechanism set on the support platform, and a material platform set at the bottom of the cross displacement mechanism.

[0006] In the preferred embodiment, the top of the conveyor table is provided with an end connection part, and the support platform is provided on the front side of the top of the end connection part.

[0007] In the preferred embodiment, a longitudinal reinforcing rib is provided between the bottom of the support platform and the front side of the end connection, a transverse reinforcing rib is provided on the side of the longitudinal reinforcing rib, and the bottom of the transverse reinforcing rib is connected to the bottom of the support platform.

[0008] In the preferred embodiment, the cross displacement mechanism includes a longitudinal alignment mechanism longitudinally arranged on the top of the support platform and a transverse alignment mechanism transversely driven on the longitudinal alignment mechanism.

[0009] In the preferred embodiment, both the longitudinal alignment mechanism and the transverse alignment mechanism include a U-shaped groove. A rotatable displacement screw and two limit rods are provided in the U-shaped groove. A drive motor with its output end connected to the displacement screw is provided on one side of the U-shaped groove.

[0010] Both the lateral alignment mechanism and the bottom of the material table are equipped with three sleeve shafts. Two of the sleeve shafts are slidably fitted onto the corresponding limit rods, and the other sleeve shaft is threaded onto the corresponding displacement screw.

[0011] In the preferred embodiment, an inverted L-shaped mounting bracket is provided on the support platform, and the image acquisition device is suspended below the end of the inverted L-shaped mounting bracket.

[0012] In the preferred embodiment, the top of the material platform is provided with an anti-slip surface.

[0013] This invention provides a digital printing precision alignment device. An alignment material platform is set on the conveyor table of a circular conveyor line, and an image acquisition device is set on the front side of the digital printing machine above the alignment material platform. The image acquisition device can be used to locate and detect the material laid flat on the alignment material platform.

Detailed Implementation

[0021] like Figure 1-5 As shown, a digital printing precision alignment device includes a support platform 1, a circular conveyor line 2 mounted on the support platform 1, and a digital printing machine 4. The digital printing machine 4 includes two support frames 401 mounted on the side of the support platform 1 and on the central axis of the support platform 1. The tops of the two support frames 401 are flush and are equipped with a digital printing body 402 that can move horizontally and vertically. The circular conveyor line 2 passes under the digital printing body 402. Each conveyor table 201 of the circular conveyor line 2 is equipped with an alignment material table 3, so that each alignment material table 3 on the circular conveyor line 2 can pass through the digital printing body 402 through the operation of the circular conveyor line 2. An image acquisition device 6 is also mounted on the support platform 1 in front of the digital printing machine 4. The image acquisition device 6 is located directly above the alignment material table 3 that passes through it, so that each alignment material table 3 that passes through it can be detected by the image acquisition device 6. In this embodiment, the image acquisition device 6 is an industrial camera.

[0022] This design allows the material to be printed to be laid flat on the alignment material table 3, and then transported by the circular conveyor line 2 through the image acquisition device 6 to the area below the digital printing body 402. As the material passes through the image acquisition device 6, it can be positioned on the alignment material table 3. If a deviation is detected, the alignment material table 3 will self-adjust to move the material to the corresponding position before it enters the area below the digital printing body 402 for printing. This eliminates the need for staff to precisely position the material when placing it, greatly improving printing efficiency while ensuring printing accuracy.

[0023] It should be noted that an electrical control device is also provided for information collection and instruction transmission of the entire device, so as to realize the operation control of the entire device. The digital printing body 402, which can move in both horizontal and vertical directions, is also a commonly used device in this field. Therefore, the electrical control device and the digital printing body 402 will not be described in detail here.

[0024] Furthermore, the alignment material platform 3 includes a support platform 32 that is set on the conveyor platform 201 and extends forward. The support platform 32 is equipped with a cross displacement mechanism, and a material platform 35 is set at the bottom of the cross displacement mechanism. The material platform 35 can move in both longitudinal and lateral directions under the action of the cross displacement mechanism, thereby achieving the effect of adjusting the alignment of the material on it.

[0025] In a preferred embodiment, an end connection portion 31 is fixedly provided on the top of the conveyor table 201, and a support platform 32 is provided on the front side of the top of the end connection portion 31. A longitudinal reinforcing rib 310 is provided between the bottom of the support platform 32 and the front side of the end connection portion 31. A transverse reinforcing rib 311 is provided on the side of the longitudinal reinforcing rib 310. The bottom of the transverse reinforcing rib 311 is connected to the bottom of the support platform 32, thereby effectively improving the supporting force of the support platform 32 by utilizing the transverse reinforcing rib 311 and the longitudinal reinforcing rib 310.

[0026] In the preferred embodiment, the cross displacement mechanism includes a longitudinal alignment mechanism 33 longitudinally arranged on the top of the support platform 32 and a transverse alignment mechanism 34 transversely arranged on the longitudinal alignment mechanism 33. The material platform 35 is transversely arranged on the transverse alignment mechanism 34, thereby realizing the longitudinal adjustment of the material platform 35 by using the longitudinal alignment mechanism 33 and the transverse alignment mechanism 34.

[0027] In the preferred embodiment, both the longitudinal alignment mechanism 33 and the transverse alignment mechanism 34 include a U-shaped groove 330. A rotatable displacement screw 331 and two limiting rods 332 are provided in the U-shaped groove 330. The displacement screw 331 is rotatably disposed in the U-shaped groove 330 through bearings and is located in the middle. The two limiting rods 332 are respectively disposed on both sides of it. A drive motor 334 with its output end connected to the displacement screw 331 is provided on one side of the U-shaped groove 330, so that the displacement screw 331 can be driven to rotate by the driving force of the drive motor 334.

[0028] Both the transverse alignment mechanism 34 and the material table 35 have three sleeve shafts 335 at their bottom. Two of the sleeve shafts 335 are slidably mounted on the corresponding limit rods 332, and the other sleeve shaft 335 is threaded onto the corresponding displacement screw 331. The transverse alignment mechanism 34 is driven onto the longitudinal alignment mechanism 33 through the three sleeve shafts 335, and the material table 35 is driven onto the transverse alignment mechanism 34 through the three sleeve shafts 335. Thus, the displacement of the transverse alignment mechanism 34 or the material table 35 is achieved by rotating the displacement screw 331.

[0029] In the preferred embodiment, an inverted L-shaped mounting bracket 5 is provided on the support platform 1, and the image acquisition device 6 is suspended below the end of the inverted L-shaped mounting bracket 5, thereby facilitating the hoisting of the image acquisition device 6 above the alignment material platform 3.

[0030] In the preferred embodiment, the top of the material platform 35 is provided with an anti-slip surface, which can effectively prevent the material from sliding on it. The anti-slip surface can be made of rubber, silicone, etc.

[0031] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
