[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0020] like Figures 1 to 4 As shown, the utility model provides an infrared pre-drying device, which includes a frame 1, an infrared mounting cavity 2 arranged on the frame 1 and a plurality of infrared components 3 arranged in the infrared mounting cavity 2, wherein the infrared components 3 include a lower mounting frame 4 arranged on the frame 1, an upper mounting frame 5 arranged on the lower mounting frame 4, a plurality of protective baffles 6 arranged on the upper mounting frame 5 and a plurality of infrared heating tubes 7 arranged on the lower mounting frame 4, and the plurality of infrared heating tubes 7 and the plurality of protective baffles 6 are arranged one by one up and down.

[0021] Specifically, the upper mounting frame 5 is arranged above the lower mounting frame 4. In actual use, the utility model can be widely used for pre-drying various strips to be dried, and the infrared heating tube 7 can adopt the existing infrared heating tube 7. The strip is repeatedly wound in the infrared mounting cavity 2, and the strip passes through the gaps of multiple protective baffles 6. The strip is dried by the infrared heating tube 7 to improve the drying efficiency of the strip. After the strip is pre-dried by the infrared heating tube 7, the strip is secondary dried in a drying box. In the actual installation process, multiple protective baffles 6 are respectively installed on the upper mounting frame 5, and multiple infrared heating tubes 7 are respectively installed on the lower mounting frame 4, and then the upper mounting frame 5 is installed on the lower mounting frame 4, and the lower mounting frame 4 is installed on the rack 1, so as to quickly and conveniently complete the installation of a whole set of infrared components 3. The infrared component 3 of the utility model is easy to install, and the whole set of infrared components 3 can be quickly disassembled and replaced, which is convenient for the maintenance of the infrared heating tube 7. A protective baffle 6 is added. When the strip material breaks unexpectedly, the protective baffle 6 can protect the infrared heating tube 7 to prevent the strip material from damaging the infrared heating tube 7, thereby increasing the service life of the utility model.

[0022] Furthermore, the protective baffle plate 6 is located above the infrared heating tube 7 , and a plurality of through holes 8 are provided on the protective baffle plate 6 .

[0023] In actual use, the protective baffle 6 protects the infrared heating tube 7, and a plurality of through holes 8 are added to facilitate the passage of light from the infrared heating tube 7, so that the light from the infrared heating tube 7 is irradiated more onto the strip, further improving the drying efficiency of the strip.

[0024] Furthermore, the infrared pre-drying device also includes a dyeing tank 9 arranged below the frame 1.

[0025] In actual use, the strip passes through the dyeing tank 9 and the infrared installation cavity 2 in sequence, the dyeing tank 9 dyes the strip, and the infrared installation cavity 2 dries the dyed strip. The dyeing tank 9 can adopt an existing structure, which will not be described here. The dyeing tank 9 and the infrared installation cavity 2 are integrated on the frame 1, and the dyeing tank 9 is arranged below the infrared installation cavity 2, so that the utility model occupies a smaller area in the horizontal direction and has a more compact structure.

[0026] Furthermore, the infrared pre-drying device also includes a cabinet door 10 arranged at the top of the frame 1, and the cabinet door 10 is used to open or close the infrared installation cavity 2.

[0027] When it is necessary to observe the condition of the tape in the infrared installation cavity 2, the cabinet door 10 can be opened for direct observation, which makes it convenient to observe the tape.

[0028] Furthermore, the infrared pre-drying device also includes a tension adjustment component 11 arranged on the frame 1, and the tension adjustment component 11 is used to adjust the tension of the external belt material.

[0029] Specifically, the tension adjustment assembly 11 includes a mounting frame 12 arranged on the frame 1, an angle sensor 13 arranged on the mounting frame 12, a rotating shaft 14 rotatably arranged on the mounting frame 12, a rocker arm 15 connected to the rotating shaft 14 at one end, a first guide shaft 16 rotatably connected to the other end of the rocker arm 15, a second guide shaft 17 rotatably arranged on the mounting frame 12, and a driver 18 rotatably arranged on the mounting frame 12; the angle sensor 13 is used to sense the rotation angle of the rotating shaft 14; the output end of the driver 18 is rotatably connected to the middle part of the rocker arm 15; the second guide shaft 17 and the first guide shaft 16 are arranged up and down.

[0030] In actual use, the strip is wound out of the infrared installation cavity 2 and then wound on the first guide shaft 16 and the second guide shaft 17 in sequence. When the tension of the strip needs to be too tight, under the action of the tension of the strip, the strip will reversely drive the first guide shaft 16 to rotate in the direction close to the second guide shaft 17 to reduce the length of the strip between the first guide shaft 16 and the second guide shaft 17, thereby reducing the tension of the strip. At the same time, the first guide shaft 16 drives the swing rod 15 and the rotating shaft 14 to rotate, and the driver 18 is synchronously compressed by the strip in the opposite direction. The angle sensor 13 senses the rotation angle of the rotating shaft 14 and sends it to the control center. The control center controls the strip in the dyeing tank 9 to quickly enter the infrared installation cavity 2 to adjust the tension of the strip to normal, and controls the driver 18 to drive the swing rod 15 to reset through the control center. The tension of the strip of the utility model is convenient to adjust, and the tension of the strip can be detected in real time to prevent the problem of breakage caused by excessive tension of the strip, and further improve the production efficiency and quality of the strip. The driver 18 can adopt an existing cylinder or linear push rod.

[0031] Furthermore, the infrared pre-drying device also includes a plurality of bevel block assemblies 19 arranged on the frame 1, and the bevel block assemblies 19 include a connecting frame 20 arranged on the frame 1 and a bevel block rod 21 rotatably arranged on the connecting frame 20, and the bevel block rod 21 is obliquely arranged on the connecting frame 20.

[0032] In actual use, the oblique blocking rod 21 can separate the strips that are sleeved in the infrared installation cavity 2 for multiple times to prevent the strips from contacting each other, making the strips more evenly colored and avoiding wear caused by contact of the strips. Adding multiple sets of oblique blocking components 19 can separate the strips at different positions. The oblique blocking rod 21 is rotatably arranged, and the friction between the oblique blocking rod 21 and the strips is small.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
