[0026] The hot pressing plate 4 is arranged on the pressing block 3 , and the swing arm 2 drives the pressing block 3 to swing so that the hot pressing plate 4 is close to the heat conducting plate 5 .

[0027] Specifically, a heat conducting plate 5 is arranged inside the base 6, a side frame 1 is arranged at one side of the base 6, and a rotating shaft 8 is arranged on the side frame 1, a swing arm 2 and a pressing block 3 are arranged on the rotating shaft 8 in sequence, an L-shaped block 22 is arranged on the pressing block 3, a slide groove 222 is symmetrically opened on the L-shaped block 22, a slider 221 is slidably arranged in the slide groove 222, a second spring 223 is arranged between the slider 221 and the slide groove 222, a connecting rod 24 matched with the slider 221 is symmetrically arranged on the swing arm 2, a hot pressing plate 4 is arranged on the pressing block 3, the swing arm 2 drives the pressing block 3 to swing so that the hot pressing plate 4 is close to the heat conducting plate 5, at least two L-shaped blocks 22 are arranged to improve the connection effect between the swing arm 2 and the pressing block 3, when the cloth is placed on the heat conducting plate 5, the hot pressing plate 4 on the pressing block 3 is driven by the swing arm 2 to flip and approach the cloth, so as to perform hot pressing on the cloth, and the device is used for detecting the hot pressing temperature and pressure of small samples of new non-woven fabrics, and can also be used for hot pressing bonding of small cloths.

[0028] As an embodiment further provided by the present invention, a second inclined portion 51 is symmetrically provided on the heat conducting plate 5, a screw 13 is rotatably provided on the base 6, an extrusion block 14 is symmetrically threadedly connected to the screw 13, and a first inclined portion 15 that fits with the second inclined portion 51 is provided on the extrusion block 14. When replacing cloths of different thicknesses, the screw 13 is rotated to make the two extrusion blocks 14 slide relative to or toward each other, so as to control the height of the heat conducting plate 5 on the base 6, that is, the distance between the heat pressing plate 4 and the heat conducting plate 5 when the heat pressing plate 4 is descended. For cloths of the same thickness, the smaller the distance, the greater the pressure of the heat pressing plate 4 on the cloth.

[0029] As an embodiment further provided by the present invention, a block 12 cooperating with the swing arm 2 is slidably provided on the side frame 1, and a first spring 11 is provided between the block 12 and the side frame 1. When the swing arm 2 contacts the block 12, the first spring 11 pushes the block 12 to extend from the side frame 1, thereby fixing the swing arm 2. The upper plane of the block 12 is inclined, and when the swing arm 2 contacts the inclined end, the block 12 will be squeezed to retract into the side frame 1.

[0030] As an embodiment further provided by the present invention, a heating wire 41 is provided on the hot pressing plate 4, and a temperature controller 7 electrically connected to the heating wire 41 is provided on the pressing block 3. The temperature controller 7 has a model of xh-w3002. The temperature controller 7 has a display screen and a switch for controlling the heating wire 41. The hot pressing temperature of the hot pressing plate 4 is adjusted by the temperature controller 7. The hot pressing temperature of the non-woven fabric is generally between 120°C and 160°C, and the hot pressing pressure is generally 1kg / cm 2 ~5kg / cm 2 The temperature or pressure is adjusted within the range between the two for detection. At the same time, when the sample is hot pressed, when the hot pressing plate 4 contacts the heat conducting plate 5, the pressure detection head 53 reads the squeezing force of the device on the cloth, which is then transmitted to the pressure display 52 through an electrical signal, making it convenient for workers to read. After multiple tests, the temperature and pressure of the sample during hot pressing are compared to obtain the optimal hot pressing temperature and pressure.

[0031] As an embodiment further provided by the present invention, a torsion spring in contact with the pressure block 3 is arranged on the rotating shaft 8, and when the swing arm 2 is pressed down, the elastic force of the torsion spring causes the swing arm 2 to slowly descend.

[0032] As an embodiment further provided by the present invention, a grip portion 21 is provided at one end of the swing arm 2, and square grooves are provided on the grip portion 21 in a circular array. The square grooves increase the friction with the hand, thereby reducing the phenomenon of arm slipping.

[0033] As an embodiment further provided by the present invention, a locking column 23 is provided on the swing arm 2, and the locking column 23 is threadedly connected to the connecting rod 24. One end of the locking column 23 has a thread and is connected to the connecting rod 24 through the thread, so that the pressure block 3 is connected to the swing arm 2.

[0034] Working principle: First, according to the thickness of the cloth, the screw 13 is controlled to rotate on the base 6, so as to control the two extrusion blocks 14 to slide towards or relative to each other, so as to control the height of the heat conducting plate 5 on the base 6, that is, to control the distance between the heat conducting plate 5 and the hot pressing plate 4 when they are in contact, and then output through the temperature controller 7 to control the heating wire 41 to heat the heating plate, and the hand grip 21 is held and applied downward to control the pressing block 3 on the side frame 1 to swing, so as to control the hot pressing plate 4 to approach the cloth on the heat conducting plate 5. When the hot pressing plate 4 contacts the cloth, the second spring 223 pushes the slider 221 to buffer the swing. The downward pressure of the arm 2 also reminds the operator that the hot pressing plate 4 has come into contact with the fabric, thereby reducing the force on the arm. The end of the swing arm 2 cooperates with the block 12, so that the hot pressing time is between 10 seconds and 30 seconds according to the thickness of the fabric. After the hot pressing is completed, the block 12 is pulled open, and the swing arm 2 moves the hot pressing plate 4 away from the fabric under the action of the torsion spring, thereby completing the hot pressing of the fabric. At the same time, the temperature and pressure values ​​during hot pressing are read through the temperature sensor 7 and the pressure display 52 and recorded. After multiple tests, the optimal hot pressing temperature and pressure values ​​during hot pressing of the non-woven fabric are obtained through data comparison.

[0035] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.

[0036] The technical solutions in the above embodiments have clearly and completely described the contents of the utility model. 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.
