Background

With the development of modern technology, various modern printers are widely used in the printing process, and printing rollers are important parts on the printers.

The printing roll is typically coated with a flexible print film on its outer wall prior to printing. Since most of the objects to be printed are located directly below the printing roller, it is necessary to ensure that the soft printing film is located at the middle position of the printing roller, so that the situation that the local parts of the objects to be printed are not contacted with the soft printing film and are subjected to missing printing is avoided.

However, in the prior art, after the packaging of the printing film is completed, an operator judges whether the printing film is positioned in the middle of the printing roller through ruler or naked eye observation, so that the detection efficiency is low, and when batch detection is needed, the condition of detection error is easy to occur due to negligence, so that the subsequent normal printing is affected.

Fig. 1 is a schematic structural view of a printing film position detecting device of the present utility model.

Detailed Description

The printed film position detecting apparatus of the present utility model will be described in more detail below with reference to the drawings, in which preferred embodiments of the present utility model are shown, it being understood that the present utility model described herein may be modified by those skilled in the art, while still achieving the advantageous effects of the present utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.

The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the utility model will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1, an embodiment of the present utility model proposes a printed film position detecting device including a detecting table 1, two sliding abutment plates 2, and a detecting member 3.

The two sliding abutting plates 2 are slidably mounted on the detecting table 1, abutting blocks 21 are arranged on the sides, close to each other, of the two sliding abutting plates 2 to bear the printing roller 4 to be detected in an extrusion mode, the two sliding abutting plates 2 slide along the sides, close to each other, of the two sliding abutting plates 2, and then the printing roller 4 to be detected is extruded through the abutting blocks 21, and therefore positioning of the printing roller 4 to be detected is completed.

In this embodiment, a specific detecting member 3 is provided to improve the accuracy of detecting the position of the printed film 5 and the detection rate instead of manually by visual inspection or manual measurement.

The detecting member 3 includes a range finder 31 and a range plate 32.

The range finder 31 is provided on the side wall of the sliding abutment plate 2.

The distance measuring plate 32 is slidably mounted on the detecting table 1 and abuts against the printing film 5 on the printing roller 4 to be detected.

To sum up, this device is through setting up distancer 31 and range finder plate 32, when needs carry out the detection to printing film 5 position, only need to wait to detect printing roller 4 butt through sliding butt plate 2 earlier, then slide range finder plate 32, make range finder plate 32 and printing film 5's tip laminating, and then measure printing film 5 one end and distance of distancer 31, then take out to wait to detect printing roller 4, and place in opposite directions, through above-mentioned step, measure printing film 5 other end and distance of distancer 31, when the printing film 5 both ends that measure are the same with distance of distancer 31, then represent printing film 5 and be in the middle part of waiting to detect printing roller 4, accord with the standard promptly, otherwise, represent that printing film 5 position skew appears.

The distance measuring plate 32 is provided with a through hole 6 matched with the printing roller 4 to be detected, so that the printing roller 4 to be detected cannot interfere when the distance measuring plate 32 moves, the distance measuring plate 32 can be abutted against the end part of the printing film 5, and subsequent measurement is facilitated.

In addition, the abutting block 21 is provided with a placement hole matched with the printing roller 4 to be detected, so as to bear and support the printing roller 4 to be detected.

In order to avoid that the distance meter 31 is blocked by the printed film 5, the distance from the end of the printed film 5 to the distance meter 31 cannot be measured. A height difference is formed between the rangefinder 31 and the printed film 5.

Specifically, the distance meter 31 is configured as a laser measuring instrument.

In a further embodiment, the detecting members 3 are provided in two groups, and the detecting members 3 in two groups are provided in an interleaved manner. The distance between the two ends of the printing film 5 is measured by the two groups of detection members 3 respectively, as shown by L1 and L2 in the figure, so as to quickly compare whether the printing film 5 is positioned at the middle position of the printing roller 4 to be detected, namely, repeated measurement is not needed, and the detection rate is further improved.

Preferably, a gap is formed between the two ranging plates 32 and the inner wall of the detection table 1, so that the range finder 31 can conveniently measure the distance by forming the gap, and the shielding is avoided in the measuring process, so that the detection precision is improved.

In other embodiments, a screw assembly 7 is also provided to control the movement of the sliding abutment plate 2, ensuring that the printing roller 4 to be inspected does not move during the inspection process.

The detection table 1 is internally provided with a screw rod assembly 7, and the sliding abutting plate 2 is in threaded connection with the screw rod assembly 7.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model.
