Description

Technical Field

[0001] This utility model belongs to the field of digital printer technology, and in particular relates to a digital printer material output detection device. Background Technology

[0002] Traditional digital printers lack real-time material output detection. After printing, the material needs to enter the drying oven. Because the drying oven speed is mismatched with the printing speed (the printing speed varies with the image width), the printed material easily accumulates and piles up on the platform, causing scratches on the image and material waste. Current technology does not solve this problem, requiring manual intervention to stop the machine, which is inefficient and costly.

[0003] Therefore, we propose a digital printer material output detection device. Utility Model Content

[0004] The purpose of this invention is to provide a device that can detect the material stacking status in real time and automatically pause printing, thereby avoiding scrap caused by material accumulation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a material output detection device for a digital printer, including an infrared sensor, a main control board and a horizontal platform;

[0007] The infrared sensor is fixed below the platform by a sensor bracket and is used to detect materials in real time;

[0008] The main control board receives infrared sensor signals and controls the printer to pause when material is detected.

[0009] In one embodiment, the platform is located between the printer output and the oven inlet.

[0010] In one embodiment, the detection direction of the infrared sensor is parallel to the platform.

[0011] In one embodiment, the infrared sensor is electrically connected to the main control board, which is also connected to the oven controller to synchronously reduce the oven transmission speed when the printer is paused.

[0012] This utility model has the following beneficial effects:

[0013] Real-time automatic detection: The infrared sensor monitors the accumulation of printing material on the platform in real time, avoiding manual intervention and significantly improving the level of automation.

[0014] Preventing material stacking and scrapping: When material sagging and accumulation are detected, the main control board immediately controls the printer to pause, effectively preventing scratches and scrapping caused by material stacking and reducing production costs.

[0015] Simple and reliable structure: The parallel detection design using a horizontal platform and infrared sensors ensures detection accuracy; the overall device is easy to install and maintain, and has low cost.

[0016] Improve production efficiency: Solve the problem of mismatch between oven and printer speeds, reduce downtime, and ensure the stability of continuous production.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] Example 1

[0026] Please see Figure 1 As shown, this utility model is a material output detection device for a digital printer, including an infrared sensor 1, a main control board 2, and a horizontal platform 3;

[0027] Infrared sensor 1 is fixed to the bottom of platform 3 via sensor bracket for real-time detection of material 4;

[0028] The main control board 2 receives the signal from the infrared sensor 1 and controls the printer to pause when material 4 is detected.

[0029] Platform 3 is located between the printer output and the oven inlet.

[0030] The detection direction of infrared sensor 1 is parallel to that of platform 3.

[0031] The infrared sensor 1 is electrically connected to the main control board 2, which is also connected to the oven controller. When the printer is paused, the oven transmission speed is reduced synchronously.

[0032] Example 2

[0033] Please see Figure 1 As shown, this embodiment provides a digital printer material output detection device, such as... Figure 1 As shown, it includes:

[0034] Infrared sensor 1: A through-beam infrared sensor is used, with its transmitter and receiver fixed on both sides below the horizontal platform 3 by a metal bracket, and the detection direction is parallel to the plane of the platform 3.

[0035] Main control board 2: Electrically connected to infrared sensor 1 via wires;

[0036] Horizontal platform 3: Located between the printer output roller and the oven conveyor belt inlet;

[0037] Oven linkage module: The output of the main control board 2 is connected to the oven controller through a relay, which can send deceleration commands synchronously.

[0038] Work process:

[0039] 1. After the printing material 4 is output from the printer, it is transferred to the drying oven via platform 3;

[0040] 2. When the oven speed is lower than the printing speed, material 4 hangs and accumulates in the platform 3 area;

[0041] 3. The drooping material 4 blocks the optical path of the through-beam infrared sensor 1, triggering an interrupt signal;

[0042] 4. The main control board 2 immediately pauses the printer's paper feed shaft 5 and simultaneously sends a speed reduction command to the oven controller;

[0043] 5. After the accumulation is eliminated (infrared signal is restored), the printing and drying speeds will automatically resume their original speeds.
