Problems solved by technology
At present, there is no device for automatic heat-sealing of inorganic films. Using traditional methods to produce heat-sealing inorganic film products requires high labor costs, long-term use of electric irons, high power consumption, and insufficient stability of manual operation, resulting in uneven composite films. , easy to wrinkle, resulting in high scrap rate

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] like Figure 1 to Figure 3 As shown, a multi-film heat sealing device includes a bracket consisting of an upper cover 11, a base 12, and a column 13, a slide rail 2, an upper slide 31, a lower slide 32, a high-frequency electric heating device 33, a cylinder 4, a metal anvil 5, and a bottom plate 6.
[0017] The bracket is open on all sides, and the upper cover 11 and the base 12 are connected by four columns 13 around, and there are four cylindrical slide rails 2 connected to the upper cover 11 and the base 12 in the inner part, and on the slide rail 2 from top to bottom The upper slide plate 31, the high-frequency electric heating device 33 and the lower slide plate 32 fixed to each other are arranged in sequence, and the heat-conductive metal anvil 5 is arranged on the lower surface of the lower slide plate 32, which is located at the same level and distribu...

The invention discloses a multi-film heat sealing device which comprises a square support, a bottom plate, a plurality of sliding rails, an electric heating mechanism and a transmission device. The four side faces of the support are open, and the support is provided with an upper cover and a base. The bottom plate is arranged on the base of the support. The sliding rails are connected with the upper cover and the base. The electric heating mechanism is installed on the sliding rails and can slide. The transmission device is arranged between the electric heating mechanism and the support and controls the electric heating mechanism to move vertically. A plurality of heat conducting metal anvils located on the same horizontal plane are arranged on the lower surface of the electric heating mechanism. Heat sealing grooves matched with the metal anvils in shape are formed in the upper surface of the bottom plate. Substrates are arranged in the heat sealing grooves. Heat sealing convex rings are arranged on the portions, close to the peripheries, of the substrates. Filter composite films can be produced in batches; by means of the opening and closing design of a limiting plate, multiple sets of multi-layer films can be overlapped completely, overlapping precision is high, and lateral moving is avoided; by means of automatic high-frequency hot pressing, the films can be fused without creasing, the rate of finished products is large, and fast production is achieved.
Description
technical field [0001] The invention relates to the field of medical and sanitary product production equipment, in particular to a multi-film heat sealing device. Background technique [0002] Due to the excellent hydrophilicity of the inorganic membrane, it is easy to deform and diverge when treated with water or treatment liquid. Therefore, before the dipping treatment, it must be covered with an organic membrane up and down, and the periphery is heat sealed. The specific operation is to flatten the three layers of film together, place the organic film on the top and bottom, and the inorganic film in the middle, and manually heat and press with an electric iron to make the upper and lower organic films coated on the inorganic film thermally bonded together. Generally between 150°C and 180°C. Inorganic film heat sealing adopts edge heat sealing, which is required to be resistant to water, alcohol, etc. After being treated with polymer organic solution and dried, the heat s...
