It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0026] Referring to Figure 1 The utility model embodiment provides an observation device, be applied to multi -process digital printing equipment, including rack 1, transmission roller 2, cutting platform 3 and material pressing assembly 4. Among them, transmission roller 2 is located in the transmission roller 2 of the opposite sides of rack 1 along the conveying direction of printing medium 10, and transmission roller 2 is used for printing medium 10 around the transmission of printing medium 10, cutting platform 3 is located between transmission roller 2 on rack 1, and cutting platform 3 is used to extract printing medium 10 sample and carries out inspection, and the number of material pressing assembly 4 is two groups, and two groups of material pressing assembly 4 are located on cutting platform 3 and are spaced apart along the conveying direction of printing medium 10, and material pressing assembly 4 is pressed tightly when printing medium 10 needs to be extracted.

[0027] When the printing medium 10 is driven by the transmission roller 2 of the observation device in the multi-process digital printing equipment, the operator can observe the printing effect of the printing process at the front end of the observation device, and since there are usually multiple color overprints in multi-process printing, when the observation device is applied to the multi-process printing equipment, the effect of the printing medium 10 after overprint in part of the process can be monitored through the observation device, so that the printing accuracy of the previous part can be adjusted in time to ensure the printing effect, and after ensuring that the printing effect of the printing medium 10 meets the requirements, the printing medium 10 is transferred to the next process, so that the accuracy of the entire multi-process printing can be effectively and timely controlled, and the situation that the printing effect is poor in the previous part of the process but the printing effect is not known until the printing is completed can be avoided, and the waste of time and material cost is avoided; the cutting platform 3 is provided, so that when further analysis and detection of the sample is required, for example, the sample cannot be observed abnormally by the human eye, and special equipment or other methods are required for detection, the sample can be extracted on the cutting platform 3 for detection; in actual production and before formal printing processing of the printing medium 10, the printing medium 10 needs to pass through each device of the multi-process digital printing equipment to form a complete cloth passing closed loop, so that the printing medium 10 is arranged in the multi-process digital printing equipment with a certain tension, and when the sample needs to be extracted, the printing medium 10 is pressed tightly by the pressing assembly 4, so that the printing medium 10 is not disconnected and runs to the unwinding unit and the winding unit in two directions when the printing medium 10 is extracted at the cutting station, so that the cloth passing work of the printing medium 10 needs to be completed again after the sample is extracted.

[0028] The observation device provided by the utility model can provide an observation platform in the process of printing operation when applied to the multi-process digital printing equipment, avoid that the printing medium in the multi-process digital printing equipment continuously flows in the multi-process to cause that the printing effect abnormality cannot be found in time, and further extract the sample for detection, so that the accuracy of the entire multi-process printing can be effectively and timely controlled, and the printing effect is improved.

[0029] Referring to Figures 1-2 Further, two cutting grooves 31 are arranged on the cutting platform 3 along the medium printing direction. The cutting grooves 31 are arranged, and when the printing medium 10 is pressed on the cutting platform 3 by the pressing assembly 4, the cutting knife can quickly cut the printing medium 10 from the cutting groove 31, so that the sample extraction efficiency can be improved.

[0030] Referring to Figure 3Further, the at least one cutting groove 31 is arranged obliquely relative to the conveying direction of the printing medium 10.

The pressing bar 42 is provided with a positioning pin 421, and the fixed bar 41 is provided with a positioning hole 411 for the positioning pin 421 to pass through. The positioning pin 421 can move in the positioning hole 411. The cooperation of the positioning pin 421 and the positioning hole 411 can guide the movement of the pressing bar 42 and also provide structural connectivity between the pressing bar 42 and the fixed bar 41, thereby improving the structural stability of the pressing bar 42. The elbow clamp is arranged on the fixed bar 41. The pressing head of the elbow clamp passes through the fixed bar 41 and is connected with the pressing bar 42. The movement of the pressing head can be controlled by controlling the rocker arm of the elbow clamp, thereby driving the fixed bar 41 to move.

[0034] It should be noted that the elbow clamp is an existing product, and the structure of the elbow clamp is not protected in this embodiment, so the structure of the elbow clamp will not be described here.

[0035] Referring to Figure 2 Further, the observation device is provided with a deviation rectifying mechanism 5 arranged at the rear end of the cutting platform 3 in the conveying direction of the printing medium 10, so that the deviation rectifying mechanism 5 can rectify the printing medium 10 output from the observation device before conveying to the next process.

On the other hand, the deviation rectifying mechanism 5 can rectify the printing medium 10 after the sample is extracted and spliced, and can rectify the printing medium 10 after splicing, so as to improve the running accuracy of the printing medium 10 and improve the printing effect.

[0036] Referring to the drawings, further, the deviation rectifying mechanism 5 is arranged below the cutting platform 3, that is, below the cutting platform 3, so that the space in the vertical direction of the observation device can be reasonably utilized to avoid the observation device being too large.

[0037] It should be noted that the deviation rectifying mechanism 5 is a commonly used deviation rectifying mechanism 5 in the art, and the structure of the deviation rectifying mechanism 5 will not be described in detail here.

[0038] The utility model also provides a kind of multi-process digital printing equipment, including aforementioned observation device. By being provided with observation device in multi-process digital printing equipment, the printing medium 10 after overprinting in part process can be effect monitored, so as to timely adjust the printing accuracy of front part to ensure printing effect, after ensuring that the printing effect of printing medium 10 meets the demand, make printing medium 10 flow to next process, can effectively, timely control the accuracy of whole multi-process printing, can avoid the situation that printing effect is not good when in front part process, but printing effect is not in line with requirements after printing is completed, avoid causing the waste of working hours and material cost.
