[0034] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0035] like Figure 1-6 As shown, a filter cloth high temperature shaping device proposed by the present invention comprises a feeder 1, a dosing machine 2, a conveyor 3, a shaping machine 4, a cooler 6 and a reclaimer 7 which are sequentially arranged along the forward direction of the filter cloth;

[0036] A roller table 11 is installed on the inner wall of the feeder 1, and a feed roller 12 and a traction roller 13 for assisting the conveyance of the filter cloth are installed on the roller table 11;

[0037] A conveyor 3 is arranged behind the feeder 1, and a conveyor roller group 31 for assisting the conveying of the filter cloth is installed on the conveyor 3. A dosing machine 2 is arranged between the feeder 1 and the conveyor 3, and a steam generator 21 is installed at the bottom end of the dosing machine 2, and a plurality of steam spraying stations 22 are installed on the top of the steam generator 21;

[0038] A setting machine 4 is arranged behind the conveyor 3, and the setting machine 4 has a setting roller group 41 built in. The upper and lower parts of the setting machine 4 are respectively provided with an upper heater 43 and a lower heater 42 for releasing heat. The setting machine 4 has a setting mechanism 5 built in. The setting mechanism 5 includes a hanging plate 51 installed on the setting machine 4 through a connecting rod, and a cylinder 52 is symmetrically installed on the hanging plate 51. The output end of the cylinder 52 is connected to a piston rod 53, and the other end of the piston rod 53 is connected to a heating plate 54, and a filter cloth transmission gap is left between two adjacent heating plates 54;

[0039] A material reclaimer 7 is arranged behind the setting machine 4 , and a cooler 6 for assisting cooling of the filter cloth is arranged between the setting machine 4 and the material reclaimer 7 .

[0040] In this embodiment, the filter cloth is heat-set in the high-temperature chamber of the setting machine 4. Since the filter cloth shrinks after heating, it will collapse tightly on the outer wall of the setting roller group 41. A setting mechanism 5 is set in the inner cavity of the setting machine 4. The cylinder 52 on the hanging plate 51 drives the heating plate 54 connected to the piston rod 53 to extend. The two groups of heating plates 54 approach the upper and lower surfaces of the filter cloth. The heating plates 54 are inclined structures. The clamping gap between the two can pass through the transmitted filter cloth. On the one hand, it plays a role in lifting and guiding the filter cloth to prevent surface cracks from occurring when the filter cloth is transmitted in a taut state, thereby affecting the integrity of the filter cloth. On the other hand, the heating end faces of the heating plates 54 are attached to the upper and lower surfaces of the filter cloth, so that the upper and lower surfaces are heated evenly, thereby improving its setting quality.

[0041] It should be noted that: there are two groups of shaping mechanisms 5, which are respectively arranged at the front and rear of the shaping machine 4. The filter cloth transmitted in the shaping machine 4 is shaped in the front and rear parts in turn, so that the shaping is balanced and the product quality is improved.

[0042] like Figure 3 As shown, the steam generator 21 has a built-in medicine box, and setting medicine is placed in the medicine box cavity. After the setting medicine is mixed with water, it is heated by the steam generator 21 to produce droplets in a steam state. The steam spray station 22 sprays the droplets on the surface of the filter cloth to attach the setting medicine to the surface of the filter cloth. The setting medicine in a steam state can penetrate into the gaps in the inner layer of the filter cloth, and the contact and adhesion effect of the two is better.

[0043] It should be added that, on the one hand, the conveyor 3 is used to transport the filter cloth attached with medicine solution in the dosing machine 2, and on the other hand, it is used to increase the transmission time of the filter cloth, wherein a water tank 32 is arranged at the inner bottom end of the conveyor 3, and the opening end of the water tank 32 is located behind the steam generator 21. During the transmission of the filter cloth attached with medicine solution droplets in the conveyor 3, the excess droplets fall into the water tank 32 under the action of gravity, so as to prevent the excess medicine solution from entering the internal chamber of the setting machine 4 and causing temperature difference change, thereby controlling the internal chamber of the setting machine 4 to be in a constant temperature and dry environment.

[0044] like Figure 4 As shown, the setting machine 4 is a semi-closed structure, with filter cloth inlet and outlet slots at the feed end and the discharge end. The slots are only used to pass the filter cloth to prevent excessive openings from causing heat to flow out of the internal chamber of the setting machine 4, thereby reducing energy waste.

[0045] In order to increase the transmission time of the filter cloth in the setting machine, further, the setting roller group 41 includes five groups of rollers, and the five groups of rollers are arranged in an inverted "W-shaped" structure, and the filter cloth is transmitted along the rollers in a serpentine shape.

[0046] It should be noted that the lower heater 42 and the upper heater 43 have the same structure and both are provided with through holes 421 for releasing heat. The lower heater 42 and the upper heater 43 both release heat through the through holes to create a high temperature environment in the chamber of the setting machine 4 .

[0047] like Figure 6 As shown, the cooling machine 6 has a built-in cooling roller group 61 for assisting the transmission of the filter cloth. A fan table 62 is provided below the cooling roller group 61. A plurality of fans 63 are mounted on the fan table 62. The fans 63 on the fan table 62 rotate to supply air, blowing the surface of the filter cloth to cool it down, assisting its cooling and facilitating the subsequent storage of the filter cloth.

[0048] Step 1: The filter cloth to be shaped is fed through the feeder 1, and the steam of the shaping liquid is attached in the dosing machine 2. The filter cloth attached with the shaping liquid is transported to the shaping machine 4 through the conveyor 3, and the excess shaping liquid drops fall into the water tank 32 during the transportation process;

[0049] Step 2: After the filter cloth enters the setting machine 4, it is transmitted along the setting roller group 41 in a serpentine shape. The heat released by the lower heater 42 and the upper heater 43 creates a high temperature environment in the setting machine 4, and cooperates with the setting mechanism 5 to perform surface ironing and setting.

[0050] Step 3: After the filter cloth is heat-set in the setting machine 4, it is transferred to the cooling machine 6 for physical cooling. The cooled filter cloth is pulled out by the material taking machine 7.

[0051] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
