Description

Technical Field

[0001] This utility model relates to the field of fabric printing and dyeing technology, and more specifically, to a tension adjustment frame for printed and dyed fabrics. Background Technology

[0002] A fabric tension adjustment frame is a mechanical device installed between various units of a printing and dyeing machine. It adjusts the fabric tension by adjusting the tension rollers, so that the fabric surface does not loosen and wrinkle or deform due to excessive stretching during dyeing, printing, drying and other processes, thereby ensuring uniform color, stable dimensions and continuous and efficient production.

[0003] During the tensioning and conveying of fabric, it is necessary to unfold the fabric. However, there is a chance that the fabric will fold after unfolding. After the fabric is tensioned, the folded fabric cannot be naturally flat, which will cause misprints or insufficient printing accuracy in subsequent printing and dyeing. Therefore, it is necessary to keep the fabric flat before tensioning. However, using tools to flatten the fabric may cause wear and tear on the fabric, affecting the accuracy of subsequent printing and dyeing. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a tension adjustment frame for printed and dyed fabrics, so as to solve the problem that the folded fabric cannot be naturally flat after being tensioned, which leads to misprints or insufficient printing accuracy in subsequent printing and dyeing due to folding.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A tension adjusting frame for printed and dyed fabrics includes connecting frames. A laying frame is fixedly connected to the top of four connecting frames. A guide post is slidably inserted into the lower surface of the laying frame. A second support plate is fixedly connected to the bottom end of each guide post. Two support stands are fixedly connected to both sides of the second support plate. A rotating cylinder is rotatably connected to the upper end of each of the two support stands. A tension adjusting roller is fixedly sleeved on the surface of the rotating cylinder. Support frames are fixedly connected to both sides of the laying frame. An air inlet hood is fixedly connected between the two support frames. An air supply fan is fixedly connected inside the air inlet hood. An air jet hood is connected to the bottom end of the air inlet hood.

[0007] Furthermore, a cross-shaped frame is fixedly connected to the upper interior of the jet shroud, and a flow divider is fixedly connected to the lower surface of the cross-shaped frame.

[0008] Furthermore, the flow divider is located inside the jet shroud, and both the flow divider and the jet shroud are frustum-shaped.

[0009] Furthermore, the air supply fan consists of fan blades and a motor.

[0010] Furthermore, a first support plate is fixedly connected to the surface of each of the four connecting frames, and a hydraulic rod is fixedly connected to the upper surface of the first support plate. The top end of the hydraulic rod is fixedly connected to the lower surface of the second support plate.

[0011] Furthermore, the lower surface of the jet hood is connected to a shield plate, and the lower surface of the shield plate is rotatably connected to multiple baffles.

[0012] Furthermore, a sub-bracket is fixedly connected to the surface of the support frame, and a heating rod is fixedly inserted into the interior of the longitudinal arm end of the sub-bracket.

[0013] Furthermore, the heating rod is inserted into the interior of the rotating cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This solution uses an air supply fan to deliver external air into the air intake hood, and guides the airflow in an inclined ring to spray onto the surface of the fabric through the diverter block, so that the fabric unfolds from the inside out, thereby achieving the purpose of keeping the fabric flat and preventing the fabric from folding. During the tensioning and conveying process, the subsequent fabric is still in a folded state, which affects the subsequent printing and dyeing of the fabric. Moreover, the non-contact unfolding will not damage the fabric.

[0016] (2) When the tension regulating roller supports the fabric, the heat generated by the heating rod increases the temperature of the tension regulating roller surface, which can shape the unfolded fabric and eliminate the creases on the fabric surface, improve the flatness of the fabric surface, and thus improve the accuracy of subsequent printing and dyeing of the fabric.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A tension adjusting frame for printed and dyed fabrics includes connecting frames 1. A laying frame 312 is fixedly connected to the top of four connecting frames 1. Guide posts 316 are slidably inserted into the lower surface of each laying frame 312. A second support plate 301 is fixedly connected to the bottom end of each guide post 316. Two support stands 311 are fixedly connected to both sides of the second support plate 301. A rotating cylinder 315 is rotatably connected to the upper end of each of the two support stands 311. A tension adjusting roller 302 is fixedly sleeved on the surface of the rotating cylinder 315. Tension adjusting rollers 302 are fixedly connected to both sides of the laying frame 312. A support frame 303 is attached, and an air intake hood 305 is fixedly connected between two support frames 303. An air supply fan 306 is fixedly connected inside the air intake hood 305. A jet hood 304 is connected to the bottom end of the air intake hood 305. A cross-shaped frame 317 is fixedly connected inside the upper end of the jet hood 304. A flow divider block 308 is fixedly connected to the lower surface of the cross-shaped frame 317. The flow divider block 308 is located inside the jet hood 304. Both the flow divider block 308 and the jet hood 304 are frustum-shaped. The air supply fan 306 consists of fan blades and a motor.

[0025] The four connecting frames 1 are fixedly connected to the surfaces of the first support plates 2. The upper surface of the first support plates 2 is fixedly connected to the hydraulic rods 309. The top of the hydraulic rods 309 is fixedly connected to the lower surface of the second support plates 301. The lower surface of the jet hood 304 is connected to the shielding plate 307. The lower surface of the shielding plate 307 is rotatably connected to multiple stop bars 310. The surface of the support frame 311 is fixedly connected to the sub-support 313. The interior of the longitudinal arm end of the sub-support 313 is fixedly inserted with a heating rod 314. The heating rod 314 is inserted into the interior of the rotating drum 315.

[0026] By adopting the above technical solution, the fabric needs to be conveyed and unfolded during the fabric printing and dyeing process. On the fabric conveying path, the fabric is placed between the masking plate 307 and the second support plate 301. Then, the second support plate 301 is moved upward by the hydraulic rod 309, which simultaneously moves the tension adjusting roller 302 upward. This allows the fabric to be lifted during the fabric conveying process, thereby achieving the purpose of adjusting the fabric tension.

[0027] Before tensioning the fabric, the air supply fan 306, consisting of fan blades and a motor, is activated to deliver external air into the air intake hood 305, and then out through the jet hood 304. Guided by the diverter block 308, the airflow is sprayed onto the surface of the fabric in an inclined ring, causing the fabric to unfold from the inside out, thereby keeping the fabric flat and preventing it from folding. During the tensioning and conveying process, the subsequent fabric remains folded, which would affect the subsequent printing and dyeing.

[0028] When the tension adjusting roller 302 is used to support the fabric, the heat generated by the heating rod 314 increases the surface temperature of the tension adjusting roller 302. This allows the unfolded fabric to be shaped and creases on the fabric surface to be eliminated during the process of the fabric being in close contact with the surface of the tension adjusting roller 302 and being conveyed, thereby improving the flatness of the fabric surface and thus improving the accuracy of subsequent printing and dyeing.

[0029] Instructions for use: First, place the fabric between the cover plate 307 and the second support plate 301;

[0030] Next, the air supply fan 306 is turned on to deliver outside air into the air intake hood 305, causing the fabric to unfold from the inside out.

[0031] Finally, the tension adjusting roller 302 is moved upward by the hydraulic rod 309 to adjust the fabric tension;

[0032] At the same time, the heat generated by the heating rod 314 shapes the unfolded fabric.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
