In the textile and printing fields, heat transfer technology is widely used due to its unique advantages, and heat transfer paper is an indispensable material in this technology. The coating uniformity of heat transfer paper directly affects the transfer effect. Uneven coating will cause problems such as color deviation, wrinkling, and arching during transfer, affecting the quality and aesthetics of the final product.

The detector is installed on the detection frame, and the detection frame can be installed on the support plate. By using a supporting plate and supporting columns for the heat transfer printing paper, the position of the paper is stabilized. However, the supporting plate and supporting columns rotate through rollers to drive the paper to be conveyed. However, the heat transfer printing paper may be uneven or not tight enough during the conveying process, resulting in a situation where a certain part of the heat transfer printing paper may not be detected.

Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0022] The present utility model provides a technical solution: As Figures 1-3As shown in the figure, in this embodiment, a device for detecting the coating uniformity of a heat transfer paper includes a printing paper coating uniformity detection mechanism 100 and a conveyor roller tensioning assembly 200. The conveyor roller tensioning assembly 200 includes a first tension rotating plate 205 and a second tension rotating plate 206. One end of the first tension rotating plate 205 and the second tension rotating plate 206 is rotatably connected to the fixed bracket 101 through a movable bolt 207. A tensioning conveying roller 202 is fixedly installed at one end of the first tension rotating plate 205 and the second tension rotating plate 206. A connecting block 213 is fixedly installed at the lower ends of the first tension rotating plate 205 and the second tension rotating plate 206. The connecting block 213 connects and fixes the telescopic guide post 209 through a connecting bolt 212. The telescopic guide post 209 is installed inside the telescopic hydraulic cylinder 208. One end of the telescopic hydraulic cylinder 208 is provided with a rotating bolt 211. The rotating bolt 211 is rotatably connected inside the fixed block 210. The fixed block 210 is welded to one end of the fixed bracket 101.

[0023] As Figures 1-2 shown, a first conveyor roller 201 is fixedly installed at the upper end of the fixed bracket 101, a winding roller 203 is fixedly installed at the lower end of the fixed bracket 101. A servo motor 204 is installed at one end of the winding roller 203. A printing paper body 104 is conveyed outside the first conveyor roller 201 and the winding roller 203. A support frame 102 is fixedly installed at the lower end of the fixed bracket 101. A detection workbench 103 is fixedly installed at the upper end of the support frame 102. A coating uniformity detection component 300 is installed on the detection workbench 103.

[0024] By driving the servo motor 204 to drive the winding roller 203 to rotate, the printing paper body 104 is further conveyed from the first conveyor roller 201 and the tensioning conveying roller 202. By an operator controlling and driving the telescopic hydraulic cylinder 208 to drive the telescopic guide post 209 to move, when the telescopic guide post 209 moves, it further drives the first tension rotating plate 205 and the second tension rotating plate 206 to rotate up and down, and further controls and adjusts the tensioning conveying roller 202 to rotate up and down. When the tensioning conveying roller 202 rotates with the first tension rotating plate 205 and the second tension rotating plate 206, the tension of the printing paper body 104 can be effectively adjusted, so as to avoid unevenness during the conveying process. By adjusting the tension of the printing paper body 104, it is avoided that the printing paper body 104 is uneven or not tight enough during the conveying process, resulting in possible undetected parts in a certain part of the heat transfer paper. Then, the coating uniformity detection component 300 on the detection workbench 103 detects the printing paper body 104.

[0025] As Figure 1 、 Figures 4-5As shown in the figure, the coating uniformity detection component 300 includes a vertical moving guide rail plate 302, which is bolted to both side ends of the detection workbench 103. A moving groove 304 is provided inside the vertical moving guide rail plate 302. A moving block 313 is slidably connected inside the moving groove 304. One end of the moving block 313 is fixedly installed with a receiving plate 312. A threaded rod 309 is rotatably connected inside the moving block 313. A rotary motor 301 is installed at the upper end of the threaded rod 309. The upper end of the receiving plate 312 is bolted and fixed to the horizontal moving guide rail plate 303. A sliding groove 305 is provided inside the horizontal moving guide rail plate 303. A sliding block 314 is slidably connected inside the sliding groove 305. A lead screw 310 is rotatably connected inside the sliding block 314. A micro motor 315 is installed at one end of the lead screw 310. One end of the sliding block 314 is bolted and fixed to the mounting plate 306. An infrared temperature detector 307 is installed at one end of the mounting plate 306.

[0026] By driving the rotary motor 301 to drive the threaded rod 309 to rotate, the threaded rod 309 rotates inside the moving block 313, further driving the moving block 313 to move vertically up and down, thereby driving the receiving plate 312 to move vertically up and down. By driving the micro motor 315 to drive the lead screw 310 to rotate, further, the lead screw 310 rotates inside the sliding block 314 and drives the sliding block 314 to move back and forth inside the horizontal moving guide rail plate 303, further driving the mounting plate 306 and the infrared temperature detector 307 to move horizontally. During the vertical and horizontal movement of the infrared temperature detector 307, the hot stamping transfer paper to be detected can be fully covered, ensuring that each part can be detected. The all-round detection avoids the occurrence of missed detection, improves the detection accuracy of the product, can continuously detect, and reduces manual intervention.

[0027] The utility model provides a device for detecting the coating uniformity of a heat transfer paper, and the specific working principle is as follows: By driving the servo motor 204 to drive the winding roller 203 to rotate, the printing paper body 104 is further conveyed from the first conveying roller 201 and the tension conveying roller 202. The operator controls the driving telescopic hydraulic cylinder 208 to drive the telescopic guide column 209 to move. When the telescopic guide column 209 moves, it further drives the first tension rotating plate 205 and the second tension rotating plate 206 to rotate up and down, and further controls and adjusts the tension conveying roller 202 to rotate up and down. When the tension conveying roller 202 rotates with the first tension rotating plate 205 and the second tension rotating plate 206, the tension of the printing paper body 104 can be effectively adjusted, so as to avoid unevenness during the conveying process. By adjusting the tension of the printing paper body 104, it is avoided that the printing paper body 104 is uneven or not tight enough during the conveying process, resulting in possible undetected parts of the heat transfer paper. Then, the coating uniformity detection component 300 of the detection workbench 103 is used to detect the printing paper body 104. The driving rotation motor 301 drives the threaded rod 309 to rotate. The threaded rod 309 rotates inside the moving block 313, and further drives the moving block 313 to move vertically up and down, thereby driving the bearing plate 312 to move vertically up and down. By driving the micro motor 315 to drive the lead screw 310 to rotate, the lead screw 310 rotates inside the sliding block 314, and drives the sliding block 314 to move back and forth inside the transverse moving guide rail plate 303, and further drives the mounting plate 306 and the infrared temperature detector 307 to move horizontally. When the infrared temperature detector 307 moves in the vertical and horizontal directions, it can fully cover the heat transfer paper to be detected, ensuring that each part can be detected. The all-round detection avoids the occurrence of undetected situations, improves the detection accuracy of the product, can continuously detect, and reduces manual intervention.
