[0002] A laminator is a device that bonds two or more layers of materials together with an adhesive to endow the original materials with new functions. For example, it is often used for films and aluminum foils, films, papers, non-woven fabrics, etc. A heating device is usually provided on a multi-layer thin film laminator. However, the existing heating devices...

[0003] The structure of the product can be referred to a multi-layer thin film laminator disclosed in the Chinese Patent Document Publication No.: CN214522067U. There are side walls, and the number of the side walls is two. One side of each side wall is fixedly connected with bearings, and the number of the bearings is six. One side of three of the bearings is clamped with a first material shaft, one side of two of the bearings is clamped with a second material shaft, and one side of the other bearing is threadedly connected with a winding shaft. One side of the side wall close to the first material shaft is rotatably connected with a first flattening shaft.

[0004] In the above structure, it is inconvenient to heat multiple thin films while threading them.

[0005] Therefore, a heating device for a multi-layer thin film laminator that can conveniently heat multiple thin films simultaneously is needed. Summary of the Utility Model

[0006] This section of the present application is used to briefly introduce concepts, which will be described in detail in the following Detailed Description section. This section of the present application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0007] To solve the technical problems mentioned in the above Background Art section, some embodiments of the present application provide a heating device for a multi-layer thin film laminator, including: a mounting frame for mounting and setting on the heating device; a plurality of opening and closing substrates movably arranged on the mounting frame; a thin film heating plate arranged on the opening and closing substrates; collection boxes located on both sides of the thin film heating plate on the opening and closing substrates, a roller shaft is rotatably connected in the collection groove, and a scraper that fits against the side surface of the roller shaft is also arranged in the collection groove.

[0008] Through the movably arranged opening and closing substrates, it is convenient to place thin films between the opening and closing plates and heat multiple thin films.

[0009] Further, the installation frame body includes two side plates and a bottom plate. The two side plates and the bottom plate form a U-shaped structure. Adjustment slots are provided on the side plates. One end of the opening and closing substrate is hinged with a connecting head that is slidably arranged in the adjustment slot. An adjustment screw rod is rotatably connected to the side plate. One end of the adjustment screw rod is inserted into the adjustment slot and passes through the connecting head and is threadedly connected to the connecting head.

[0010] By rotating the adjustment screw rod to drive the connecting head to slide, thereby driving the connecting head to move, and then driving the opening and closing substrate to move, the distance between the opening and closing substrates is adjusted, which is convenient for controlling the distance between the film heating plate and the film, so as to ensure the heating effect.

[0011] Further, the connecting head has a side plate portion for supporting the opening and closing substrate.

[0012] By supporting the opening and closing substrate with the side plate portion, the opening and closing substrate is limited to be parallel to the film.

[0013] Further, the other end of the opening and closing substrate is threadedly connected with a bolt that passes through the opening and closing substrate, and the head end of the bolt is supported on the side plate for supporting the opening and closing substrate.

[0014] After adjusting the distance between the opening and closing substrates through the connecting head, by rotating the set bolt, the length of the head of the bolt passing through the opening and closing substrate is adjusted, so that the head of the bolt is supported on one side plate to support the opening and closing substrate.

[0015] Further, the opening and closing substrates are arranged in a stepped structure in sequence on the installation frame body, and the projections of multiple opening and closing substrates on the horizontal plane do not overlap.

[0016] By arranging the opening and closing substrates in a stepped structure in sequence, it is convenient for the opening and closing substrates to be opened in sequence, which is convenient for putting multiple films in.

[0017] Further, a part of the side surface of the roller shaft is located outside the collection box and is farther away from the side of the film heating plate where the opening and closing substrate is located, so that the roller shaft supports the film to avoid contacting the film heating plate.

[0018] By the provided roller shaft, it is avoided that the film contacts the film heating plate and is damaged.

[0019] Further, a receiving cavity is arranged in the collection box, a scraper is slidably arranged in the receiving cavity, and an elastic member is also arranged in the receiving cavity. Two ends of the elastic member respectively abut against the wall of the receiving cavity and the scraper.

[0020] By the provided scraper, the impurities attached to the surface of the roller shaft are scraped off.

[0021] Further, the surface of the roller shaft is coated with an anti-adhesion material.

[0022] By the anti-adhesion material, it is avoided that the heated film adheres to the surface of the roller shaft.

[0023] Furthermore, the roller shaft is a hollow cylinder, and a plurality of groups of through holes are formed in the side surface of the roller shaft. An air pump is arranged on the opening and closing substrate, and the air outlet end of the air pump is communicated with the inner cavity of the roller shaft through a rotary seal.

[0024] The air is discharged through the vent holes to prevent the heated film from contacting the surface of the roller shaft.

[0025] The beneficial effect of the present application is that it provides a heating device for a multi-layer film laminating machine that facilitates simultaneous heating of multi-layer films. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive. Those skilled in the art should understand that unless clearly stated otherwise in the context, it should be understood as "one or more".

[0039] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0040] Referring to Figures 1-4 , a heating device of a multi-layer film laminating machine includes: a mounting frame 100, an opening and closing substrate 101, a film heating plate 102, a collection box 103, a roller 104, and a scraper 105. The mounting frame 100 includes: two side plates 106 and a bottom plate 107. The two side plates 106 and the bottom plate 107 form a U-shaped structure. A plurality of adjustment slots 109 are provided on one side plate 106. A plurality of opening and closing substrates 101 are provided and are arranged in a stepped structure in sequence on the mounting frame 100. The projections of the plurality of opening and closing substrates 101 on the horizontal plane do not overlap. One end of the opening and closing substrate 101 is hinged with a connection head 108 that is slidably arranged in the adjustment slot 109. An adjustment screw 110 is rotatably connected to the side plate 106. One end of the adjustment screw 110 is inserted into the adjustment slot 109 and passes through the connection head 108 and is threadedly connected to the connection head 108. By rotating the adjustment screw 110, the connection head 108 is driven to slide, thereby driving the connection head 108 to move, and thus driving the opening and closing substrate 101 to move to adjust the distance between the opening and closing substrates 101.

[0041] In one embodiment, the connecting head 108 has side plate portions 111 for supporting the opening and closing substrate 101. When the opening and closing substrate 101 is rotated to be perpendicular to the connecting head 108 for convenient insertion of the thin film, and then the opening and closing substrate 101 is rotated so that the opening and closing substrate 101 is parallel to the thin film, the side plate portions 111 support the opening and closing substrate 101.

[0042] In another embodiment, a bolt 112 passing through the opening and closing substrate 101 is threadedly connected to the other end of the opening and closing substrate 101, and the head end of the bolt 112 is supported on the side plate 106 for supporting the opening and closing substrate 101. After adjusting the spacing of the opening and closing substrate 101 through the connecting head 108, the length of the head of the bolt 112 passing through the opening and closing substrate 101 is adjusted by rotating the bolt 112 at the same time, so that the head of the bolt 112 is supported on the side plate 106 on one side to ensure that the opening and closing substrate 101 is parallel to the thin film.

[0043] The thin film heating plates 102 are fixedly arranged on the upper and lower side surfaces of the opening and closing substrate 101. The collection boxes 103 are detachably installed on both sides of the thin film heating plates 102 on the opening and closing substrate 101. A roller shaft 104 is rotatably connected in the collection box 103. A part of the side surface of the roller shaft 104 is located outside the collection box and is farther away from the side of the thin film heating plate 102 away from the opening and closing substrate 101, so that the roller shaft 104 supports the thin film to avoid contacting the thin film heating plate 102. When the thin film is heated, the unwinding roller and the winding roller cooperate to make the thin film move. When the thin film is slack, the roller shaft 104 supports the thin film to avoid the thin film contacting the thin film heating plate 102.

[0044] In one embodiment, a motor is fixedly arranged on the collection box 103, and the power output end of the motor is fixedly connected to the roller shaft 104. The rotational linear speed of the roller shaft 104 is the same as the winding and unwinding speed of the thin film.

[0045] In one embodiment, the surface of the roller shaft 104 is coated with an anti-sticking material, and the anti-sticking material is a Teflon coating.

[0046] In another embodiment, the roller shaft 104 is a hollow cylinder, and a plurality of groups of through holes 113 are formed in the side surface of the roller shaft 104. An air pump is arranged on the opening and closing substrate 101, and the air outlet end of the air pump is in a cylindrical structure, and one end of the cylindrical shape extends into the roller shaft 104. Air flow is discharged through the through holes 113 to prevent the thin film from sticking to the roller shaft 104.

[0047] A receiving cavity 114 is arranged in the collection box 103, and the scraper 105 is slidably arranged in the receiving cavity 114.

[0048] In another embodiment, an elastic member 115 is further arranged in the receiving cavity 114, and both ends of the elastic member 115 are respectively abutted against the wall of the receiving cavity 114 and the scraper 105. The elastic member 115 is a spring.

[0049] Working process: Open the opening and closing substrate 101 to facilitate the film to be placed between the two opening and closing substrates 101 in sequence, and then heat multiple films. Heat the film through the film heating plate 102. When the film becomes slack, the roller 104 supports the film to prevent the film from being damaged. When adhesion occurs on the roller 104, clean the roller 104 with the scraper 105.

[0050] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
