Description

Technical Field

[0001] The utility model belongs to the technical field of heat pressing, and specifically relates to a high-temperature heat pressing mechanism. Background Art

[0002] In the film lamination process, heat pressing is a key process step, which directly affects the adhesion and overall quality of the film. Traditional heat pressing mechanisms usually complete the process in one heat pressing process. However, due to the characteristics of the film material, a single heat pressing is difficult to fully achieve the ideal effect. Therefore, a new mechanism is needed that can perform heat pressing on the film material twice in a shorter time to improve the heat pressing effect. Utility Model Content

[0003] The purpose of the present invention is to provide a high-temperature hot pressing mechanism, which can perform hot pressing treatments on the film material twice in sequence in a short time through two hot pressing rollers, thereby improving the hot pressing effect.

[0004] The technical solutions adopted in this utility are as follows:

[0005] A high-temperature hot pressing mechanism comprises a bracket on which two groups of hot pressing rollers are arranged in parallel. The hot pressing rollers comprise high-temperature resistant rubber rollers and heating rollers which are arranged in parallel vertically and rotatably. The spacing between the high-temperature resistant rubber rollers and the heating rollers is adjustable.

[0006] Furthermore, a downward pressure cylinder is fixedly connected to the upper side of the bracket, and an output end of the downward pressure cylinder is connected to a high temperature resistant rubber roller.

[0007] Furthermore, a vertically arranged sliding groove is provided on the bracket, and a small support connected to the output end of the downward pressure cylinder is vertically slidably connected inside the sliding groove, and the high temperature resistant rubber roller is rotatably connected to the small support.

[0008] Furthermore, a stepping motor connected to the heating roller is fixedly connected to the bracket.

[0009] Furthermore, the high temperature resistant rubber roller is located on the upper side of the heating roller.

[0010] Furthermore, rotor bearings are installed between the heating roller and the bracket and between the high temperature resistant rubber roller and the small support.

[0011] The technical effects achieved by this utility model are:

[0012] The high-temperature hot pressing bonding mechanism of the present invention can improve the hot pressing effect by arranging two hot pressing rollers to perform hot pressing treatments on the film material twice in sequence within a short period of time. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0019] like Figure 1-3 As shown, a high-temperature hot pressing mechanism comprises a bracket 1, on which two sets of hot pressing rollers are mounted, the hot pressing rollers comprise a high-temperature resistant rubber roller 2 and a heating roller 3 which are vertically arranged in parallel and rotatable, and the distance between the high-temperature resistant rubber roller 2 and the heating roller 3 is adjustable;

[0020] At this time, when hot pressing is carried out, the film material is passed through the gap between the high-temperature resistant rubber roller 2 and the heating roller 3 in the two sets of hot pressing rollers, and then the distance between the high-temperature resistant rubber roller 2 and the heating roller 3 is adjusted to make the high-temperature resistant rubber roller 2 and the heating roller 3 fit tightly with the film material. In the process of the film material passing through the high-temperature hot pressing mechanism, the two hot pressing rollers will perform hot pressing treatment on the film material twice in turn in a short time to improve the hot pressing effect.

[0021] Among them, there are many ways to move the high-temperature resistant rubber roller 2 or the heating roller 3, such as manual adjustment and electric adjustment. The electric adjustment is selected in the present technical solution. Specifically, the upper side of the bracket 1 is fixedly connected with a downward pressure cylinder 4, and the output end of the downward pressure cylinder 4 is connected to the high-temperature resistant rubber roller 2. At this time, the distance between the high-temperature resistant rubber roller 2 and the heating roller 3 can be adjusted by moving the high-temperature resistant rubber roller 2, and the adjustment method is relatively simple.

[0022] Moreover, in order to improve the stability of the high temperature resistant rubber roller 2, a vertically arranged sliding groove 6 is opened on the bracket 1. The interior of the sliding groove 6 is vertically slidably connected with a small support 7 connected to the output end of the downward pressure cylinder 4. The high temperature resistant rubber roller 2 and the small support 7 are rotatably connected. At this time, the horizontal deviation of the high temperature resistant rubber roller 2 is limited by the small support 7, so that the horizontal displacement of the high temperature resistant rubber roller 2 can be reduced and the stability can be improved.

[0023] At the same time, a stepping motor 5 connected to the heating roller 3 is fixedly connected to the bracket 1. The heating roller 3 can be driven to rotate by the kinetic energy output of the stepping motor 5, thereby reducing the friction force on the film material when it moves.

[0024] Among them, the position of the high temperature resistant rubber roller 2 is preferably located on the upper side of the heating roller 3. Compared with setting the heating roller 3 on the upper side, the heating roller 3 set on the lower side can contact the lower side of the film material, which better reduces the friction force on the film material when it moves.

[0025] At the same time, rotor bearings are installed between the heating roller 3 and the bracket 1 and between the high temperature resistant rubber roller 2 and the small support 7 to reduce the friction force when the high temperature resistant rubber roller 2 and the heating roller 3 rotate.

[0026] The working principle of the utility model is: when performing heat pressing, the film material is passed through the gap between the high-temperature resistant rubber roller 2 and the heating roller 3 in the two sets of heat pressing rollers, and then the distance between the high-temperature resistant rubber roller 2 and the heating roller 3 is adjusted by the downward pressure cylinder 4, so that the high-temperature resistant rubber roller 2 and the heating roller 3 are closely fitted to the film material. In the process of the film material passing through the high-temperature heat pressing mechanism, the two heat pressing rollers will perform two heat pressing treatments on the film material in turn in a short time, thereby improving the heat pressing effect.

[0027] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
