[0009] When the cloth in the preheating box is transported to the drying oven, the cloth has a certain temperature in advance, which shortens the heating time of the wet cloth in the drying oven to a certain extent, so that the drying oven can heat and shape more wet cloth per unit time, which saves energy to a certain extent and improves the working efficiency of the drying oven.

[0011] By adopting the above technical solution, after the filter assembly has been working for a long time, a certain amount of lint may be attached to the filter assembly. The operator can loosen the limit nut to release the limit bolt and the limit nut from limiting the first limit plate and the second limit plate, thereby detaching the cylinder body from the cover body. After detaching the cylinder body from the cover body, the operator can clean the filter assembly in the cylinder body, maintain the filtering quality and filtering efficiency of the filter assembly to a certain extent, thereby improving the preheating quality of the cloth to a certain extent.

[0012] Optionally, the filter assembly includes a first filter plate and a second filter plate, the first filter plate is located directly below the second filter plate, the first filter plate is provided with a first filter hole, the second filter plate is provided with a second filter hole, and the aperture of the first filter hole is larger than the aperture of the first filter hole.

[0013] By adopting the above technical solution, the high-temperature steam entering the preheating box passes through the first filter and the second filter in sequence. By setting the first filter and the second filter, the high-temperature steam is filtered twice to remove the fluff mixed in the high-temperature steam as much as possible, thereby improving the preheating quality of the cloth to a certain extent.

[0014] Optionally, the first filter plate and the second filter plate are installed on the cylinder in the same manner. Taking the first filter plate as an example, a first clamping block is fixedly connected to the first filter plate, a first clamping groove is opened on the inner wall of the cylinder along the axial direction of the cylinder, and a second clamping groove is opened on the inner wall of the cylinder along the circumferential direction of the cylinder. The first clamping groove and the second clamping groove are connected, and the first clamping block slides with the first clamping groove and the second clamping groove.

[0015] By adopting the above technical solution, when in use, the operator aligns the first clamping block of the first filter plate with the first clamping groove, and the first clamping groove is opened along the axial direction of the cylinder.

The first clamping block is clamped and matched with the third clamping groove. When the first filter is installed in the third clamping groove, the first clamping block is fixedly connected with the third clamping groove along the circumferential direction of the cylinder, and under the action of gravity, the first clamping block is always tightly pressed against the bottom of the third clamping groove on the side away from the first clamping groove. The provision of the third clamping groove further improves the stability of the first filter installed on the cylinder.

[0021] By adopting the above technical solution, assuming that the high-temperature steam in the first row of heat pipes directly passes through the first filter and the second filter, most of the high-temperature steam will pass through the area where the first filter and the second filter are located directly above the first row of heat pipes, while the amount of high-temperature steam passing through the edge areas of the first filter and the second filter is small, that is, the lint will mainly be concentrated in the area where the first filter and the second filter are located directly above the first row of heat pipes, and the effective utilization rate of the first filter and the second filter is low.

[0022] By setting up the first heat removal plate, after the high-temperature steam passes through the first heat removal plate, the high-temperature steam in the first heat removal pipe is evenly divided into several portions, and each portion of the high-temperature steam passes through the first filter plate and the second filter plate in turn.

At this time, a step surface is formed between the cover body and the sealing block, that is, a step surface is formed at the connection between the cover body and the cylinder body, which further improves the sealing between the cover body and the sealing block, that is, reduces the probability of high-temperature steam overflowing from the connection between the cover body and the cylinder body.

[0025] Optionally, a mounting frame is fixedly connected to the inside of the cover body, and a sealing ring is sleeved on the mounting frame. The outer diameter of the sealing ring is matched with the inner diameter of the cylinder.

[0053] The implementation principle of a shaping machine with waste heat recycling function in the embodiment of the present application is as follows: the conveyor belt 120 is used to transport the cloth to be shaped, and the cloth is driven by the conveyor belt 120 and passes through the preheating box 130 and the oven 110 in sequence. The preheating box 130 preheats the cloth to make the cloth have a certain temperature in advance, and the oven 110 dries and shapes the preheated cloth.

[0054] When the oven 110 dries and shapes the fabric, a certain amount of high-temperature steam is generated. The high-temperature steam enters the filter cartridge 200 through the first heat discharge pipe 230, and the high-temperature steam first passes through the first heat discharge plate 250. The first heat discharge holes 260 provided on the first heat discharge plate 250 evenly divide the high-temperature steam into eight parts. The high-temperature steam passes through the first filter sheet 310 and the second filter sheet 320 in sequence, and the first filter sheet 310 and the second filter sheet 320 block the lint in the high-temperature steam.

[0055] The filtered high-temperature steam enters the second heat exhaust pipe 240. A portion of the high-temperature steam entering the second heat exhaust pipe 240 is discharged from the exhaust pipe 270, and the other portion of the high-temperature steam enters the preheating box 130. The high-temperature steam entering the preheating box 130 preheats the cloth.

[0056] After the first filter 310 and the second filter 320 have been working for a long time, the operator can loosen the limit bolt 410 and the limit nut 420 to separate the cover 220 of the filter cartridge 200 from the cartridge 210. The disassembly method of the first filter 310 and the second filter 320 is the same. Taking the disassembly of the first filter 310 as an example, the operator first pulls the first filter 310 vertically upward. At this time, the first clamping block 330 on the first filter 310 is separated from the third clamping groove 343 and enters the second clamping groove 342. The operator rotates the first filter 310. At this time, the first clamping block 330 slides along the second clamping groove 342 until the first clamping block 330 slides to the slot of the first clamping groove 341. The operator then pulls the first filter 310 vertically upward. At this time, the first clamping block 330 slides vertically upward along the first clamping groove 341, and the first filter 310 is taken out. The second filter 320 is taken out in the same way.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
