Description

Technical Field

[0001] This utility model relates to the technical field of chemical protective clothing production equipment, specifically a heat sealing device for chemical protective clothing production. Background Technology

[0002] Chemical protective suits are a type of protective clothing. Firefighting protective suits are crucial equipment for protecting the personal safety of firefighters on the front lines of firefighting. Also known as protective clothing, protective work clothes, or firefighting suits, they generally feature high coverage, a tight seal, and ease of operation. Firefighting protective suits are specialized protective equipment used to protect firefighters from flames and radiant heat. To ensure the airtightness of chemical protective suits, lightweight chemical protective suits are typically manufactured using a combination of sewing and heat sealing. While sewing requires less investment, the sewn areas have poorer sealing performance due to the presence of seam holes, resulting in relatively lower chemical protection. Therefore, heat sealing has gradually replaced sewing as the primary method.

[0003] Chinese utility model patent CN220283014U discloses a heat-sealing device for producing chemical protective suits. The device comprises: a workbench on which a first roll of adhesive fabric and a second roll of adhesive fabric are rotatably mounted, both of which are wound with adhesive fabric; a lower mold base on the workbench, on which a lower mold is mounted; a support frame on the workbench, on which a hydraulic cylinder and an upper mold base are mounted; and an upper mold and a heat-sealing mechanism are mounted on the upper mold base.

[0004] However, the fabric winding wheel of the heat sealing device for producing chemical protective clothing cannot adjust the winding pressure, which easily leads to wrinkles or excessive stretching of the coated fabric, affecting the heat sealing quality. At the same time, the limiting roller is prone to accumulating dust and impurities, contaminating the fabric and reducing the cleanliness and quality of the product. Therefore, a heat sealing device for producing chemical protective clothing is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a heat-sealing device for the production of chemical protective suits, which has advantages such as adjustable pressure and good cleaning effect, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A heat-sealing device for producing chemical protective clothing includes a workbench, a heat-sealing mechanism disposed on the top of the workbench, and a first roll of adhesive fabric and a second roll of adhesive fabric rotatably connected to one side of the top of the workbench. One side of the top of the workbench is provided with an adjustable winding mechanism for winding adhesive fabrics of different thicknesses and materials, and the other side of the top of the workbench is provided with a cleaning device. The adjustable winding mechanism includes a mounting frame fixedly connected to the top of the workbench. A drive motor is fixedly mounted on the outside of the mounting frame. A winding roller is fixedly connected to the output shaft of the drive motor. An electric push rod is fixedly mounted on the top of the mounting frame. A slider is fixedly connected to the output end of the electric push rod. A pressure roller is rotatably connected inside the slider. The cleaning device includes a suction tube and a mounting box located on the top of the workbench. A negative pressure fan is rotatably connected to the outside of the mounting box, and a delivery pipe is fixedly connected between the mounting box and the suction tube.

[0007] Furthermore, the mounting bracket has an internal groove that matches the slider, and the slider and the groove are slidably connected.

[0008] Furthermore, there are two sets of electric push rods and sliders. The two sets of electric push rods and sliders are symmetrically distributed on the upper surface of the mounting frame and extend into its interior. The pressure roller is rotatably connected to the interior of the two sets of sliders and is located on top of the take-up roller.

[0009] Furthermore, a conveying mechanism is provided on the top of the workbench. The conveying mechanism includes a fixed frame fixedly connected to the top of the workbench. A conveying roller is rotatably installed inside the fixed frame. A geared motor is fixedly installed outside the fixed frame. The output shaft of the geared motor is fixedly connected to one end of the conveying roller.

[0010] Furthermore, the mounting box is fixedly connected to the outside of the fixing frame, and the suction tube is fixedly installed inside the fixing frame and located on the upper surface of the conveying roller.

[0011] Furthermore, a collection plate is slidably connected inside the mounting box, and a movable port adapted to the collection plate is opened inside the mounting box. A check valve is fixedly installed inside the conveying pipe.

[0012] Furthermore, the heat sealing mechanism includes a support frame and a lower mold fixedly installed on the top of the workbench. A hydraulic cylinder is fixedly installed on the top of the support frame, and an upper mold is fixedly connected to the output end of the hydraulic cylinder. The upper mold is located directly above the lower mold.

[0013] Furthermore, both the front and rear sides of the upper mold are rotatably connected to abutting rollers via connecting ears, and the two sets of abutting rollers are symmetrically distributed on the outside of the upper mold in a front-to-back manner.

[0014] Compared with the prior art, this utility model provides a heat-sealing device for the production of chemical protective suits, which has the following beneficial effects: 1. The heat-sealing device for producing chemical protective suits uses an electric push rod to extend and retract a slider that moves up and down within a chute. This allows the pressure roller to move closer to or further away from the take-up roller, precisely adjusting the pressure of the take-up roller on the coated fabric. This satisfies the different take-up pressures required for coated fabrics of varying thicknesses and materials, effectively preventing fabric wrinkles or excessive stretching due to improper pressure, improving take-up quality, and providing qualified fabric for subsequent production processes.

[0015] 2. The heat-sealing device for producing chemical protective suits uses a negative pressure fan to create negative pressure inside the installation box. The suction pipe draws dust, impurities, and production debris from the surface of the conveyor rollers into the installation box. A check valve prevents backflow of impurities, and the collection plate can be easily removed to clean the collected impurities. This effectively prevents contaminants from contacting the coated fabric, which helps improve product quality and protective performance. The conveyor rollers are driven by a geared motor to provide power for the transfer of the coated fabric on the workbench, allowing the fabric to pass through each processing stage smoothly and continuously.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3The heat sealing device for producing chemical protective clothing in this embodiment includes a workbench 1, a heat sealing mechanism 2 disposed on the top of the workbench 1, and a first coated fabric roll 3 and a second coated fabric roll 4 rotatably connected to one side of the top of the workbench 1. An adjustable winding mechanism 5 for winding coated fabrics of different thicknesses and materials is provided on one side of the top of the workbench 1, and a cleaning device 7 is provided on the other side of the top of the workbench 1. The heat sealing mechanism 2 includes a support frame 21 and a lower mold 24 fixedly installed on the top of the workbench 1. A hydraulic cylinder 22 is fixedly installed on the top of the support frame 21. An upper mold 23 is fixedly connected to the output end of the hydraulic cylinder 22. The upper mold 23 is located directly above the lower mold 24.

[0020] Specifically, the front and rear sides of the upper mold 23 are rotatably connected to abutting rollers 25 via connecting ears, and the two sets of abutting rollers 25 are symmetrically distributed on the outside of the upper mold 23.

[0021] In this embodiment, the adjustable winding mechanism 5 includes a mounting frame 51 fixedly connected to the top of the workbench 1. A drive motor 52 is fixedly mounted on the outside of the mounting frame 51, and a winding roller 53 is fixedly connected to the output shaft of the drive motor 52. An electric push rod 54 is fixedly mounted on the top of the mounting frame 51, and a slider 55 is fixedly connected to the output end of the electric push rod 54. A pressure roller 56 is rotatably connected inside the slider 55. By extending and retracting the electric push rod 54, the slider 55 moves up and down in the groove, thereby causing the pressure roller 56 to move closer to or further away from the winding roller 53, which can precisely adjust the pressure of the winding roller 53 on the coated fabric.

[0022] The mounting frame 51 has a groove inside that matches the slider 55, and the slider 55 and the groove are slidably connected. There are two sets of electric push rods 54 and two sets of sliders 55. The two sets of electric push rods 54 and sliders 55 are symmetrically distributed on the upper surface of the mounting frame 51 and extend into its interior. The pressure roller 56 is rotatably connected to the interior of the two sets of sliders 55 and is located on top of the take-up roller 53.

[0023] In this embodiment, a conveying mechanism 6 is provided on the top of the workbench 1. The conveying mechanism 6 includes a fixed frame 61 fixedly connected to the top of the workbench 1. A conveying roller 62 is rotatably mounted inside the fixed frame 61, and a geared motor 63 is fixedly mounted outside the fixed frame 61. The output shaft of the geared motor 63 is fixedly connected to one end of the conveying roller 62. The geared motor 63 drives the conveying roller 62 to rotate, providing power for the transfer of the coated fabric on the workbench 1, so that the fabric can pass through each processing stage smoothly and continuously. At the same time, the suction tube 74 of the cleaning device 7 is installed inside the fixed frame 61 and located on the upper surface of the conveying roller 62, which can clean the surface of the fabric in real time during the transfer process; the adjustable winding mechanism 5 winds up the cleaned and processed fabric. All stages work closely together to form a complete production process, improving production efficiency and automation.

[0024] In this embodiment, the cleaning device 7 includes a suction pipe 74 and a mounting box 71 disposed on the top of the workbench 1. A negative pressure fan 72 is rotatably connected to the outside of the mounting box 71, and a delivery pipe 75 is fixedly connected between the mounting box 71 and the suction pipe 74.

[0025] The mounting box 71 is fixedly connected to the outside of the fixing frame 61, and the suction pipe 74 is fixedly installed inside the fixing frame 61 and located on the upper surface of the conveying roller 62.

[0026] Specifically, a collection plate 73 is slidably connected inside the mounting box 71, and a movable opening adapted to the collection plate 73 is provided inside the mounting box 71. A check valve is fixedly installed inside the conveying pipe 75. During production, the negative pressure fan 72 is started to create negative pressure inside the mounting box 71. The suction pipe 74 draws dust, impurities, and production debris from the surface of the conveying roller 62 into the mounting box 71 through the conveying pipe 75. The check valve prevents impurities from flowing back. The collection plate 73 can be easily pulled out to clean the collected impurities.

[0027] The working principle of the above embodiments is as follows: In use, the coated fabric is sequentially fed from the first coated fabric roll 3 and the second coated fabric roll 4 around the conveying roller 62 in the conveying mechanism 6, and through the suction pipe 74 in the cleaning device 7, finally reaching the take-up roller 53 in the adjustable take-up mechanism 5; the geared motor 63 drives the conveying roller 62 to rotate, ensuring stable conveying of the coated fabric; the negative pressure fan 72 generates negative pressure through the conveying pipe 75 and the suction pipe 74, adsorbing dust and impurities on the surface of the limiting roller, and conveying the impurities to the collection plate 73 in the mounting box 71 through the conveying pipe 75, keeping the surface of the limiting roller clean; the collection plate 73 can be removed and cleaned periodically, reducing manual maintenance time and costs; the electric push rod 54 drives the slider 55 to move up and down in the groove in the mounting frame 51, so that the pressure roller 56 moves closer to or further away from the take-up roller 53, thereby adjusting the pressure of the pressure roller 56 on the coated fabric; by adjusting the electric push rod 54, the pressure of the pressure roller 56 on the coated fabric can be adjusted. The telescopic length of push rod 54 can precisely control the pressure of pressure roller 56 on the coated fabric, adapting to fabrics of different thicknesses and materials, preventing wrinkles or excessive stretching during winding, and improving heat sealing quality. During heat sealing, the coated fabric is conveyed to the lower mold 24 of the heat sealing mechanism 2. Hydraulic cylinder 22 drives upper mold 23 to press down, and the contact roller 25 first contacts the coated fabric and adheres it tightly to the fabric, ensuring that the fabric is flat and adhered to the lower mold 24. Upper mold 23 continues to press down, and heat sealing mechanism 2 performs heat sealing treatment on the coated fabric. After heat sealing is completed, hydraulic cylinder 22 drives upper mold 23 to rise, preparing for the next heat sealing operation. During winding, drive motor 52 drives winding roller 53 to rotate, winding the coated fabric after heat sealing. Pressure roller 56, driven by electric push rod 54, applies appropriate pressure to the coated fabric to ensure that the fabric is flat during winding.
