Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 3 As shown, a high elastic non-woven fabric hot pressing forming device includes an operating table 11, a mounting seat 12 is fixedly connected to the upper end of the operating table 11, a conveyor belt 13 for conveying non-woven fabric is arranged in the mounting seat 12 (the conveyor belt 13 is driven by a conveyor roller, and the conveyor roller is driven by a motor, which is not shown in the figure), and a carrying plate 14 is fixedly connected to the mounting seat 12 in the conveyor belt 13, and the carrying plate 14 gives the conveyor belt 13 a certain supporting force to prevent the conveyor belt 13 from collapsing downward during the hot pressing process;

[0027] The operating table 11 is fixedly connected with a mounting plate above the conveyor belt 13, and a lifting cylinder 15 is fixedly connected to the mounting plate. A hot pressing plate 16 is fixedly connected to the piston rod of the lifting cylinder 15, and the hot pressing plate 16 presses down the non-woven fabric on the conveyor belt 13, so that it is heated and formed;

[0028] Furthermore, the operating platform 11 is provided with a limiting roller group for limiting the non-woven fabric on one side of the conveyor belt 13, and a cold air mechanism for accelerating the cooling of the non-woven fabric is fixedly connected to the operating platform 11 below the limiting roller group;

[0029] The limiting roller group driven by the motor (not shown in the figure) can effectively prevent the non-woven fabric from floating upward due to the airflow blown out by the cold air mechanism during the transmission process.

[0030] In addition, a collecting box 33 is provided on the side of the limiting roller group away from the operating table 11, a connecting plate 17 is provided between the limiting roller group and the collecting box 33, and a collecting mechanism for collecting the thermoformed non-woven fabric is provided in the collecting box 33.

[0031] The working principle of the utility model is as follows: after the non-woven fabric to be processed is placed on the conveyor belt 13, the non-woven fabric is located directly below the hot pressing plate 16 after the position is adjusted by the conveyor belt 13, and then the lifting cylinder 15 drives the hot pressing plate 16 to move downward and press the non-woven fabric, thereby hot-pressing the non-woven fabric. After the hot pressing is completed, the conveyor belt 13 drives the non-woven fabric to enter the limiting roller group, and the cold air mechanism cools the non-woven fabric. The non-woven fabric after cooling enters the collecting box 33. The above structure accelerates the cooling speed of the non-woven fabric, shortens the cooling time required for the non-woven fabric, and thus improves production efficiency.

[0032] The cooling air mechanism includes a blower 18, an air supply pipe 19 and an air outlet pipe 20;

[0033] The specific structure of the cold air mechanism is as follows: the air outlet pipe 20 is arranged directly below the limiting roller group, a working chamber 21 is opened in the operating table 11, the blower 18 is installed in the working chamber 21, and a plurality of communication holes are opened on the side of the working chamber 21, one end of the air supply pipe 19 is connected to the air outlet of the blower 18, and the other end of the air supply pipe 19 extends to the outside of the working chamber 21 and is connected to the air outlet pipe 20, and a plurality of ventilation holes are opened at the upper end of the air outlet pipe 20. During the hot pressing operation, the blower 18 produces airflow and cools the non-woven fabric through the air outlet pipe 20, thereby accelerating the cooling speed of the non-woven fabric.

[0034] In addition, the limiting roller group includes a plurality of transmission rollers 22 arranged vertically, and the transmission rollers 22 can squeeze the non-woven fabric while transmitting the non-woven fabric, so that the layers of raw materials of the non-woven fabric can fit more closely, and a supporting short plate 34 is fixedly connected between each of the transmission rollers 22, and a plurality of ventilation holes (not shown in the figure) are opened on the supporting short plate 34 for air flow to pass through, and the supporting short plate 34 can give the non-woven fabric a certain supporting force to prevent the non-woven fabric from falling between each of the transmission rollers 22, and the ventilation gap can make the airflow blown out of the air outlet pipe 20 contact with the non-woven fabric, and a transition plate 35 is provided between the transmission roller 22 and the conveyor belt 13 on the side close to the conveyor belt 13, and the transition plate 35 can prevent the non-woven fabric from falling between the transmission roller 22 and the conveyor belt 13 during the transmission process.

[0035] The collecting mechanism includes a placement plate 23 and a piezoresistive sensor 24, and the piezoresistive sensor 24 is fixedly connected to the lower end of the placement plate 23;

[0036] The collecting box 33 is provided with a collecting chamber 25, in which a reciprocating screw rod 26 is rotatably connected, the placing plate 23 is threadedly connected to the reciprocating screw rod 26, and the collecting box 33 is provided with a rotating assembly for driving the reciprocating screw rod 26 to rotate.

[0037] The non-woven fabric after cooling is moved to the placement plate 23 through the connecting plate 17, and the piezoresistive sensor 24 converts the weight change of the placement plate 23 into an electromagnetic signal and transmits it to the controller (not shown in the figure). The rotating assembly moves downward according to the signal so that the non-woven fabric falling into the collection box 33 can be neatly stacked on the placement plate 23, which is convenient for the operators to collect.

[0038] The rotating assembly includes a first bevel gear 27, a second bevel gear 28 and a servo motor 29;

[0039] The first bevel gear 27 is fixedly connected to the lower end of the reciprocating screw 26 , the servo motor 29 is fixedly connected to the outer end of the hot pressing plate 16 , the second bevel gear 28 is fixedly connected to the output shaft of the servo motor 29 , and the second bevel gear 28 is meshed with the first bevel gear 27 .

[0040] The servo motor 29 cooperates with the first bevel gear 27 via the second bevel gear 28 , thereby driving the reciprocating screw rod 26 to rotate.

[0041] The operating table 11 is provided with a cleaning seat 30 below the conveyor belt 13 . The cleaning seat 30 is provided with a dirt collecting groove 31 . The cleaning seat 30 is provided with an inclined scraper 32 on one side of the dirt collecting groove 31 .

After the adhesive solidifies, the surface of the conveyor belt 13 will be uneven. If it is not removed in time, it will affect the flatness of the non-woven fabric after hot pressing. The inclined scraper 32 can scrape off the residual adhesive on the surface of the conveyor belt 13, and the scraped adhesive falls into the sump 31. The mounting seat 12 is provided with a through opening for the cleaning seat 30 to pass through. The operator can take out the cleaning seat 30 through the through opening and clean the adhesive in the sump 31.
