[0002] During the production process of medical bedding, the fabric needs to be hot-pressed and laminated by a heat-sealing device. The hot-pressing and laminating process of the fabric is a process of spraying glue and heating on the injection-molded skeleton and manually covering the fabric. The hot-pressed and laminated fabric generally has back foam and non-woven fabric. During lamination, the non-woven fabric can prevent the glue from penetrating into the foam and cloth, avoiding uneven fabric thickness.

[0003] A Chinese patent with publication number CN205853541U discloses an easy-to-use fabric glue composite hot pressing machine. By adopting a liquid heating and hot pressing structure, the pressing surface is heated evenly, and the glue is evenly distributed by adopting an elastic vibration structure, so that the fabric bonding is more uniform. It is highly electric and mechanized, easy and quick to use, and meets the quality requirements of the work.

[0004] The heat sealing device in the above patent document can only fix fabrics of a single thickness, that is, it can only perform composite heat pressing treatment on fabrics of a single thickness, and cannot quickly fix fabrics of different thicknesses, so its practicality is poor.

Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0025] Reference Figure 1-Figure 5 A heat sealing device for the production of medical bedding, comprising a platform 1, a glue groove 2 is provided on the upper surface of the platform 1, a U-shaped mounting plate is fixedly installed on the upper surface of the platform 1, an electric telescopic rod 3 is fixedly installed on the lower surface of the mounting plate, a pressing roller 4 is fixedly installed at the bottom end of the driving shaft of the electric telescopic rod 3, a liquid groove is provided in the pressing roller 4, a heat-conducting liquid is filled in the liquid groove, and an electric heating rod is provided in the liquid groove;

[0026] The front and rear surfaces of the pressure roller 4 are fixedly installed with fixed blocks, and a rotating shaft 5 is rotatably installed on the surface of the fixed block. A mounting roller 6 is fixedly installed at one end of the rotating shaft 5. A positioning groove 7 for the end of the fabric to enter is horizontally opened on the surface of the mounting roller 6. Two through openings respectively connected to the two positioning grooves 7 are horizontally opened on the surface of the mounting roller 6. A positioning plate 8 is slidably arranged in the through opening. A first threaded rod 9 is rotatably installed on the surface of the mounting roller 6. A slider 10 is threadedly sleeved on the first threaded rod 9. The slider 10 is fixedly connected to the positioning plate 8 through a connecting plate 11. The two rotating shafts 5 are controlled to rotate by a transmission assembly. The transmission assembly includes two gears 12 respectively fixedly sleeved on the two rotating shafts 5, two rack rods 13 respectively meshed with the two gears 12, and a second threaded rod 14 vertically rotatably installed on the upper surface of the pressure roller 4. A slide plate 15 is threadedly sleeved on the second threaded rod 14. The slide plate 15 is fixedly connected to the two rack rods 13 through two connecting rods.

[0027] First, place the fabric to be heat-sealed under the pressure roller 4, and place the two ends of the fabric in the two positioning grooves 7 respectively, then control the positioning plate 8 to move by rotating the first threaded rod 9, until the positioning plate 8 presses the fabric in the positioning groove 7 tightly against the positioning groove 7 to complete the fixation of the fabric, and then control the slide plate 15 to move with the two rack rods 13 by rotating the second threaded rod 14, and the two gears 12 respectively meshed with the two rack rods 13 will respectively drive the two rotating shafts 5 and the two mounting rollers 6 to rotate, so as to roll up the fabric and make it straight until the fabric can fit tightly with the pressure roller 4, at this time, the heat-conducting liquid in the liquid tank is heated by the electric heating rod, and then the electric telescopic rod 3 is started to make the fabric enter the glue tank 2 and contact with the glue in the glue tank 2.

[0028] The groove wall of the positioning groove 7 and the surface of one end of the positioning plate 8 close to the positioning groove 7 are both bonded with an anti-slip layer, and the material of the anti-slip layer is rubber;

[0029] The anti-skid layer made of rubber material has good elasticity and viscosity, so that the friction between the positioning plate 8, the positioning groove 7 and the contact surface of the fabric can be increased, thereby improving the effect of positioning the fabric.

[0030] A scraper assembly is provided on the surface of the pressure roller 4, and the scraper assembly is used to scrape off excess glue on the surface of the fabric. The scraper assembly includes a sliding block 16, a spring rod 17 fixedly installed on the lower surface of the sliding block 16, and a scraper 18 fixedly installed at the bottom end of the spring rod 17. A sliding frame 19 is fixedly installed on one side of the pressure roller 4 through a connecting rod. The sliding block 16 is horizontally slidably arranged in the sliding frame 19. The sliding block 16 is controlled to move by a pressing component. The pressing component includes an inclined plate 20 fixedly installed at the bottom of the sliding block 16, a support rod vertically fixedly installed at the bottom of the glue tank 2, and an I-shaped block 21 fixedly installed at the top of the support rod. A sliding opening 22 is opened on the surface of the inclined plate 20, and the I-shaped block 21 is slidably arranged in the sliding opening 22;

[0031] When the fabric is placed under the pressure roller 4, it needs to be located between the scraper 18 and the pressure roller 4. Then, when the fabric moves toward the glue groove 2, the I-shaped block 21 will slide in the slide 22. Under the action of the inclined surface pressure, the scraper 18 will move horizontally. Then, when the fabric moves out of the glue groove 2, the scraper 18 will move in the direction opposite to the direction of movement just now. During the movement, the scraper 18 will slide in contact with the fabric, so that excess glue on the surface of the fabric can be scraped off and fall into the glue groove 2. While avoiding waste, the excess glue can also be recycled.

[0032] In the utility model, the fabric to be heat-sealed is first placed under the pressing roller 4, and the two ends of the fabric are placed in the two positioning grooves 7 respectively, and then the first threaded rod 9 is rotated to control the positioning plate 8 to move until the positioning plate 8 presses the fabric in the positioning groove 7 tightly against the positioning groove 7 to complete the fixing of the fabric, and then the two rotating shafts 5 and the two mounting rollers 6 are controlled by the transmission component to rotate relative to each other, and the fabric is rolled up to make it straight, until the fabric can fit tightly with the pressing roller 4, at this time, the heat-conducting liquid in the liquid tank is heated by the electric heating rod, and then the electric telescopic rod 3 is started to make the fabric enter the glue tank 2 and contact with the glue in the glue tank 2, so that fabrics of different thicknesses can be quickly fixed, and at the same time, the fabric can be straightened to make its surface flat and fit tightly with the pressing roller 4, which improves the practicality of the device and improves the heat-sealing effect.

[0033] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
