[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] refer to Figure 1-4A specific embodiment of the utility model provides a new type of sealing strip for a laminator, which is installed between the upper cavity strip 4 and the hot pressing plate 6 of the laminator. The first sealing side of the sealing strip is set as a square head strip 1, and the square head strip 1 is installed on the upper cavity strip 4. The second sealing side of the sealing strip is set as an arc strip 2, and the arc strip 2 is set in contact with the hot pressing plate 6.

[0024] At present, the commonly used ones in the industry are round rubber strips 7 or square rubber strips 5. The round rubber strips 7 are constantly deformed and aged with the increase of working times during use, which affects the service life and weakens the sealing effect. The square rubber strips 5 increase the overall strength of the rubber strips during use, but increase the installation accuracy a lot, which is easy to cause air leakage, and the square rubber strips 5 are prone to cracking as the working time increases. In the present application, a square-headed strip 1 and an arc-shaped strip 2 are respectively provided on the two relative sealing sides of the sealing strip, the square-headed strip 1 is used to increase the supporting strength of the sealing strip and the square-headed strip 1, and the arc-shaped strip 2 is used to improve the sealing effect between the sealing strip and the hot pressing plate 6; on the whole, the present application can effectively increase the overall strength and sealing effect of the sealing strip.

[0025] Further optimization plans also include:

[0026] The notch 8 is formed on the first sealing side of the upper cavity bead 4 close to the hot pressing plate 6 , and the square head bead 1 is fitted into the notch 8 .

[0027] The main function of the notch 8 is to install the square-headed bead 1 of the sealing strip so that the deformation of the square-headed bead 1 in the notch 8 is minimized and the supporting strength is large enough.

[0028] Further optimization plans also include:

[0029] The shoulder 3 is formed at the connection between the square head bead 1 and the arc bead 2 on both sides, and the shoulder 3 abuts against the first sealing side surface of the upper cavity bead 4 close to the hot pressing plate 6.

[0030] The shoulder 3 is arranged between the square-headed bead 1 and the arc-shaped bead 2, so that during the deformation of the arc-shaped bead 2, the shoulder 3 plays a supporting role, thereby greatly improving the service life of the rubber strip.

[0031] According to a further optimized solution, the width of the square head pressure strip 1 is 18 mm-18.5 mm, and the height is 11.8 mm-12.2 mm.

[0032] The width of the square head bead 1 is 18.2 mm and the height is 12 mm. This arrangement can effectively increase the overall strength of the sealing strip and adapt to the installation of the upper cavity bead 4 and the hot pressing plate 6.

[0033] According to a further optimized solution, the cross section of the arc-shaped bead 2 is semicircular, and the arc-shaped side surface of the arc-shaped bead 2 is arranged away from the square-head bead 1.

[0034] The arc-shaped pressure strip 2 with a semicircular cross section utilizes the high sealing property of the circular structure to maximize the sealing effect.

[0035] According to a further optimization scheme, the radius of the arc-shaped layering strip 2 is 12 mm-13 mm.

[0036] The radius of the arc-shaped bead 2 is 12.5 mm. This arrangement enables the sealing strip to more fully contact the hot pressing plate 6, thereby ensuring a sufficient sealing effect.

[0037] According to a further optimization scheme, the distance between the shoulder 3 and the side surface of the square head bead 1 is 6 mm-7.8 mm, that is, the shoulder 3 exceeds the size of the side surface of the square head bead 1.

[0038] The distance between the shoulder 3 and the side of the square head strip 1 is 6.8 mm. With this arrangement, when the upper cavity strip 4 is connected to the hot pressing plate 6, the shoulder 3 can play a supporting role during the extrusion and deformation of the arc strip 2, thereby effectively improving the service life of the sealing strip.
