Description

Technical Field

[0001] The utility model relates to the technical field of thermal films, in particular to a thermal film drying detection structure. Background Art

[0002] After the thermal film is dried, it needs to be tested to determine whether it has reached sufficient drying standards. Since the thermal film is in a long strip state during drying, it is difficult to test the film in pieces. Therefore, the testing standards and accuracy are difficult to control and unify, so it is impossible to make an accurate judgment, which makes it difficult to judge the drying effect in a timely manner.

[0003] To this end, we propose a thermal film drying detection structure to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a thermal film drying detection structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A thermal film drying detection structure includes a door frame, a column, and a roller. There are multiple columns, which are fixed on the lower end surface of the door frame. The number of rollers is equal to the number of columns. The lower end of the column is provided with an embedding groove, and the roller is rotatably connected to the column in the embedding groove. The roller is provided with multiple holes, which are distributed in a circular shape on the roller, and an infrared detection head is installed in each of the holes.

[0007] Preferably, the distance between each of the columns is no less than 7 cm.

[0008] Preferably, a pair of sponge pads are fixedly connected to the edge of the roller.

[0009] Preferably, a glass sheet is fixedly connected to the end of the hole.

[0010] Preferably, a laser emitter is embedded in the top of the embedding groove, and a laser receiver is installed in the hole.

[0011] Preferably, the laser receiver and the infrared detection head are arranged side by side, and the height of the laser receiver is higher than that of the infrared detection head.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Through the coordination of the set columns, rollers and infrared detection heads, the column is used to fix the rollers, so that the rollers are in contact and relative motion with the thermal film moving forward, thereby driving the rollers to rotate. During the rotation, the infrared detection head detects the stability of the thermal film, thereby forming an image of the temperature of the entire thermal film, and judging the drying effect of each position of the whole through the stability of the area.

[0014] 2. Through the coordination of the laser transmitter and the laser receiver, the laser emitted by the laser transmitter is received by the laser receiver, so that the infrared detection head of the corresponding group refreshes the signal, resets the data to zero, and forms a complete distance count. The distance the roller rolls is calculated to compare the actual distance the thermal film moves, thereby improving the accuracy and controllability of reading temperature.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] After the thermal film is dried, it needs to be tested to determine whether it has reached the drying standard. Since the thermal film is in a long strip state during drying, it is difficult to test the film in sections. Therefore, the test standard and accuracy are difficult to control and unify, so it is impossible to make an accurate judgment, which makes it difficult to judge the drying effect in time. Figure 1-3 The traditional humidity detection method cannot be used for thermal film. This scheme designs a thermal film drying detection structure, including a door frame 1, a column 2, and a roller 3. The column 2 is provided with multiple columns. The door frame 1 spans above the thermal film conveyor belt that has undergone the drying operation. Since the width of the thermal film is relatively fixed, the distance between each column 2 is maintained at not less than 7 cm to evenly cover most of the area that should be detected by the thermal film.

[0021] The column 2 is fixed on the lower end surface of the door frame 1. The number of rollers 3 is equal to the number of columns 2. A groove 4 is provided at the lower end of the column 2. During installation, the roller 3 is rotatably connected to the column 2 in the groove 4 so that the roller 3 can move freely. A laser transmitter 8 is embedded in the top center of the groove 4 for detecting and resetting the movement of the roller 3, and a laser receiver 9 is installed in the hole.

[0022] A plurality of holes are provided on the roller 3, and a glass sheet 7 is fixedly connected to the end of the hole for sealing the hole. The plurality of holes are distributed in a circular shape on the roller 3, and a pair of sponge ring pads 6 are fixedly connected to the edge of the roller 3 for supporting the roller 3, so that the roller 3 does not directly contact the thermal film, but contacts the thermal film through the sponge ring pads 6. The sponge ring pads 6 have a good friction coefficient and will not easily damage the thermal film.

[0023] The detection method is as follows: an infrared detection head 5 is installed in each hole, a laser receiver 9 is arranged side by side with the infrared detection head 5, and the height of the laser receiver 9 is higher than that of the infrared detection head 5. During the detection, as the roller 3 rotates, the infrared detection head 5 continuously measures the temperature of the thermal film at the corresponding position. The measurement time is as follows: the laser receiver 9 starts timing after receiving the laser transmitter 8. Since the moving speed of the thermal film is fixed, the infrared detection head 5 will be turned on and measured at a specific time. The measurement transmits and records the data, so as to determine whether the temperature of the thermal film at the corresponding position remains normal, and to determine whether the drying program is normal.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
