Description

Technical Field

[0001] This invention relates to the field of protective clothing production technology, specifically to a seam sealing device for protective clothing production. Background Technology

[0002] Protective clothing includes fire-fighting protective clothing, industrial protective clothing, medical protective clothing, military protective clothing, and protective clothing for special groups. Protective clothing is mainly used in industries and departments such as fire fighting, military, shipbuilding, petroleum, chemical, painting, cleaning and disinfection, and laboratories. During the production of protective clothing, the seams of the fabric need to be sealed using a seam sealing machine.

[0003] According to the hot air seam sealing machine for protective clothing described in Chinese Patent No. CN212666733U, the protective clothing cannot be effectively heat-sealed, resulting in poor sealing and easy internal delamination and damage. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a seam sealing device for the production of protective clothing, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a seam sealing device for protective clothing production, comprising a body, an adhesive device disposed within the inner cavity of the body, a guide channel fixedly connected to the surface of the body in front of the adhesive device, a conveyor belt rotatably connected to the inner cavity of the guide channel, a straightening box fixedly connected to the inner cavity of the guide channel, a semiconductor heater fixedly connected to the inner cavity of the straightening box, temperature-conducting blocks connected to both sides of the semiconductor heater via a connecting structure, a temperature-conducting plate fixedly connected to the bottom of the temperature-conducting blocks, a drive shaft rotatably connected to the inner cavity of the straightening box, a straightening wheel and a temperature-conducting wheel rotatably connected to the surface of the drive shaft located within the inner cavity of the straightening box, the surface of the temperature-conducting wheel abutting against the surface of the temperature-conducting plate, two straightening wheels symmetrically distributed on both sides of the temperature-conducting wheel, and guide grooves formed on the surface of both straightening wheels.

[0006] As a further aspect of the present invention: the guide patterns on the surfaces of the two straightening wheels are arranged in opposite directions, both facing away from the heat-conducting wheel.

[0007] As a further aspect of the present invention: the surface of the temperature guiding wheel abuts against the adhesive part of the protective clothing, and the surface of the straightening wheel abuts against both sides of the adhesive part of the protective clothing.

[0008] As a further aspect of the present invention: the side of the temperature guiding plate is provided with an arc shape that fits the surface of the temperature guiding wheel.

[0009] As a further aspect of the present invention: the connection structure includes a connection frame fixed to one side of the semiconductor heater, and the inner cavity of the connection frame is provided with an insertion groove for insertion into the surface of the temperature-conducting block.

[0010] As a further aspect of the present invention: the top of the straightening box is threaded with a connecting bolt, one end of which passes through the straightening box, the connecting frame and the temperature-conducting block in sequence and extends into the inner cavity of the temperature-conducting block. The surface of the connecting bolt is threadedly connected to the inner cavities of the connecting frame and the temperature-conducting block, respectively.

[0011] As a further aspect of the present invention: two temperature-conducting blocks are provided, and are respectively connected to the heating end and the cooling end of the semiconductor heater, with the heating end of the semiconductor heater located behind the cooling end.

[0012] During use, the protective suit, after being seam-sealed and glued, is conveyed into the guide channel and transported by a conveyor belt to a location below the semiconductor heater. The semiconductor heater then operates, heating the rear temperature-conducting rollers and cooling the front temperature-conducting rollers. Simultaneously, the straightening rollers stretch the protective suit to both sides, preventing wrinkles. The temperature-conducting rollers then press against the surface of the protective suit, heating the interior for more thorough heat contact. The suit is then conveyed to a location below the cooling temperature-conducting rollers, where it rapidly cools and solidifies. During heat conduction, temperature is transferred to the surface of the temperature-conducting plate via temperature-conducting blocks. A connecting structure allows for quick installation and removal of the temperature-conducting blocks. Disassembly involves removing the connecting bolts, pulling them out of the straightening box, connecting frame, and temperature-conducting blocks, removing the worn temperature-conducting blocks, replacing them, and inserting the new blocks into the slots within the connecting frame. The connecting bolts are then rotated to lock the temperature-conducting blocks in place, and the process continues.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This invention effectively utilizes the cooling and heating functions of a semiconductor heater. It first heats the garment to ensure close contact, then rapidly cools and shapes it. The rear heat-conducting roller provides heat while cooling the front heat-conducting roller. At this time, the straightening roller stretches the protective clothing to both sides through the surface of the straightening roller and the heat-conducting roller, preventing wrinkles. Then, the heat-conducting roller presses against the surface of the protective clothing, providing heat to the interior and ensuring more thorough heating and contact. The clothing is then transported to the cooling heat-conducting roller, which allows the protective clothing to cool and solidify rapidly.

[0015] 2. The present invention adopts a connection structure that allows for quick disassembly and assembly of the temperature-conducting block. During disassembly, the connecting bolt is removed and pulled out from the straightening box, connecting frame and temperature-conducting block. The worn temperature-conducting block is removed and replaced. After replacement, the new temperature-conducting block is inserted into the insertion slot in the connecting frame. Then, the connecting bolt is rotated to lock the temperature-conducting block in the connecting frame and continue working. Attached Figure Description

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] Please see Figure 1-4This invention provides a technical solution: a seam sealing device for protective clothing production, comprising a body 1, an adhesive device disposed in the inner cavity of the body 1, a guide channel 2 fixedly connected to the surface of the body 1 in front of the adhesive device, a conveyor belt 3 rotatably connected to the inner cavity of the guide channel 2, a straightening box 4 fixedly connected to the inner cavity of the guide channel 2, a semiconductor heater 9 fixedly connected to the inner cavity of the straightening box 4, temperature-conducting blocks 12 connected to both sides of the semiconductor heater 9 via connecting structures, a temperature-conducting plate 14 fixedly connected to the bottom of the temperature-conducting blocks 12, a drive shaft 5 rotatably connected to the inner cavity of the straightening box 4, a straightening wheel 7 and a temperature-conducting wheel 6 rotatably connected to the surface of the straightening box 4 on the drive shaft 5, the surface of the temperature-conducting wheel 6 abutting against the surface of the temperature-conducting plate 14, two straightening wheels 7 are provided and symmetrically distributed on both sides of the temperature-conducting wheel 6, and guide grooves 8 are formed on the surface of both straightening wheels 7. In use, the protective clothing after seam sealing is conveyed into the guide channel 2 and transported by the conveyor belt 3 to the semi-finished section. Below the conductor heater 9, the semiconductor heater 9 is currently operating, supplying heat to the rear heat-conducting roller 6 and cooling the front heat-conducting roller 6. At this time, the straightening roller 7 stretches the protective suit to both sides below the heat-conducting roller 6, preventing wrinkles. Then, the heat-conducting roller 6 presses against the surface of the protective suit, supplying heat to the interior for more thorough heat contact. The heat is then transported to the cooling heat-conducting roller 6, where it rapidly cools and solidifies. During heat conduction, through… The temperature-conducting block 12 transfers temperature to the surface of the temperature-conducting plate 14. The connection structure allows for quick disassembly and assembly of the temperature-conducting block 12. During disassembly, the connecting bolt 13 is removed and pulled out from the straightening box 4, the connecting frame 10, and the temperature-conducting block 12. The worn temperature-conducting block 12 is then removed and replaced. The new temperature-conducting block 12 is then inserted into the insertion slot 11 in the connecting frame 10. The connecting bolt 13 is then rotated to lock the temperature-conducting block 12 in the connecting frame 10, and the operation can continue.

[0023] The guide patterns 8 on the surfaces of the two straightening rollers 7 are set in opposite directions, both facing away from the side of the heat-conducting roller 6. The straightening rollers 7 are stretched to both sides by the protective clothing below the heat-conducting roller 6 on the surface of the straightening rollers 7 to prevent wrinkles from forming.

[0024] The surface of the heat-conducting roller 6 abuts against the adhesive part of the protective suit, and the surface of the straightening roller 7 abuts against both sides of the adhesive part of the protective suit. The heat-conducting roller 6 presses against the surface of the protective suit to heat the inside, making the heat contact more thorough. Then it is transported to the bottom of the cooling heat-conducting roller 6, and the protective suit is quickly cooled and shaped through the heat-conducting roller 6.

[0025] The side of the heat-conducting plate 14 has an arc shape that fits the surface of the heat-conducting wheel 6, resulting in more thorough contact and better heat conduction.

[0026] The connection structure includes a connection frame 10 fixed to one side of the semiconductor heater 9. The inner cavity of the connection frame 10 has an insertion groove 11 for inserting into the surface of the temperature-conducting block 12. The top of the straightening box 4 is threaded with a connecting bolt 13. One end of the connecting bolt 13 passes through the straightening box 4, the connection frame 10 and the temperature-conducting block 12 in sequence and extends into the inner cavity of the temperature-conducting block 12. The surface of the connecting bolt 13 is threaded into the inner cavities of the connection frame 10 and the temperature-conducting block 12 respectively. During disassembly, the connecting bolt 13 is removed and pulled out from the straightening box 4, the connection frame 10 and the temperature-conducting block 12. The worn temperature-conducting block 12 is removed, and after replacement, the new temperature-conducting block 12 is inserted into the insertion groove 11 in the connection frame 10. Then, the connecting bolt 13 is rotated to lock the temperature-conducting block 12 in the connection frame 10 and continue working.

[0027] Two heat-conducting blocks 12 are provided, and they are respectively connected to the heating end and the cooling end of the semiconductor heater 9. The heating end of the semiconductor heater 9 is located behind the cooling end, effectively utilizing the cooling and heating functions of the semiconductor heater 9 to first heat it to make it in close contact, and then quickly cool it to solidify it.

[0028] In use, the protective suit, after being sewn and glued, is conveyed into the guide channel 2 and then transported by the conveyor belt 3 to a position below the semiconductor heater 9. At this time, the semiconductor heater 9 operates, heating the rear temperature guide roller 6 and cooling the front temperature guide roller 6. Simultaneously, the straightening roller 7 stretches the protective suit to both sides below the temperature guide roller 6, preventing wrinkles. Then, the temperature guide roller 6 presses against the surface of the protective suit, heating the interior for more thorough heat contact. Finally, the suit is conveyed to a position below the cooling temperature guide roller 6, where it is further heated by the temperature guide roller. Wheel 6 enables the protective suit to cool and solidify quickly. During heat conduction, the temperature is transferred to the surface of the temperature-conducting plate 14 through the temperature-conducting block 12. The connecting structure allows for quick installation and removal of the temperature-conducting block 12. During disassembly, the connecting bolt 13 is removed and pulled out from the straightening box 4, connecting frame 10, and temperature-conducting block 12. The worn temperature-conducting block 12 is then removed and replaced. The new temperature-conducting block 12 is then inserted into the insertion slot 11 in the connecting frame 10. Finally, the connecting bolt 13 is rotated to lock the temperature-conducting block 12 in the connecting frame 10, and the work can continue.
