Abstract
Description
Technical Field
[0001] This utility model relates to the field of nonwoven fabric production equipment, and in particular to a disinfection and sterilization device for nonwoven fabric production. Background Technology
[0002] Non-woven fabric is a common non-textile material, and materials made from it are very common in daily life, from small items like masks and disposable slippers to large items like disposable bed sheets. During the production of non-woven fabric, especially when producing products with high hygiene requirements, it is necessary to disinfect the fabric. A common disinfection method is to soak the non-woven fabric in disinfectant and then dry it. However, the non-woven fabric becomes heavier after being soaked, and it is easy to stretch during movement, leading to damage. Therefore, developing a disinfection and sterilization device for non-woven fabric production that reduces the stretching of the fabric during movement is particularly necessary. Summary of the Invention
[0003] The purpose of this invention is to provide a disinfection and sterilization device for non-woven fabric production, which has the advantage of reducing the stretching of non-woven fabric during movement.
[0004] The technical solution adopted is as follows:
[0005] A disinfection and sterilization device for nonwoven fabric production includes a disinfection tank with two limiting rollers inside. Feeding rollers and an extrusion unit are respectively installed at both ends of the disinfection tank. The extrusion unit includes a frame located at the upper end of the disinfection tank. A fixed roller is rotatably mounted on the frame, and a moving roller is positioned diagonally above the fixed roller. The frame is equipped with a lifting mechanism connected to the moving roller. A plate chain conveyor is inclinedly mounted on the frame. The plate chain conveyor includes multiple chain plates connected end-to-end. Pressure plates are hinged to both ends of each chain plate, and coil springs are installed between the pressure plates and the chain plates. Vertical guide plates are installed on both sides of the plate chain conveyor.
[0006] Preferably, the lifting mechanism includes two vertically extending electric telescopic rods, the upper ends of which are rotatably connected to fixed rollers on the same side.
[0007] Preferably, the outer surfaces of the fixed roller and the moving roller are uniformly provided with multiple anti-slip strips.
[0008] Preferably, the end of the chain plate is provided with a limiting block corresponding to the pressure plate on the same side.
[0009] Preferably, a support plate is provided in the disinfection pool below the limiting roller.
[0010] Preferably, the disinfection pool is equipped with a liquid level alarm.
[0011] Compared to existing technologies, the advantages are:
[0012] 1. In this utility model, the disinfection pool is filled with disinfectant. The nonwoven fabric passes under the limiting roller and enters the extrusion unit along the inclined plate chain conveyor. The disinfectant contained in the nonwoven fabric is squeezed out and flows back into the disinfection pool. During the movement of the nonwoven fabric on the plate chain conveyor, the pressure plate is guided by the action guide plate so that when the chain plate is above the plate chain conveyor, the pressure plate presses on the chain plate, thereby clamping the two ends of the nonwoven fabric and reducing the stretching of the nonwoven fabric during the movement.
[0013] 2. In this utility model, a support plate is provided below the limiting roller to support the non-woven fabric and reduce the stretching of the non-woven fabric after it is wetted. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 4 As shown:
[0020] Example 1: A disinfection and sterilization device for nonwoven fabric production includes a disinfection tank 1 with an opening at the top. The disinfection tank 1 is filled with disinfectant solution. A drain valve 2 is provided at the bottom of the disinfection tank 1 to drain the disinfectant solution. Two limiting rollers 4 are provided inside the disinfectant solution. The two limiting rollers 4 have the same specifications and the same installation height. Feeding rollers 6 and extrusion units are respectively provided at both ends of the disinfection tank 1. The feeding rollers 6 guide the nonwoven fabric entering the disinfection tank 1. The nonwoven fabric passes over the feeding rollers 6 and passes under the limiting rollers 4.
[0021] The extrusion unit includes a frame 7, which is located at the upper end of the disinfection tank 1. A fixed roller 8 is rotatably mounted on the frame 7, and a drive motor 9 is fixedly mounted on the frame 7. The drive motor 9 is connected to the fixed roller 8 and drives the fixed roller 8 to rotate. A movable roller 10 is located diagonally above the fixed roller 8. The movable roller 10 has the same specifications as the fixed roller 8. The frame 7 is equipped with a lifting mechanism connected to the movable roller 10. The lifting mechanism controls the lifting and lowering of the movable roller 10, thereby adjusting the distance between the movable roller 10 and the fixed roller 8. When the nonwoven fabric is inserted between the movable roller 10 and the fixed roller 8, the distance between the movable roller 10 and the fixed roller 8 is increased to facilitate the passage of the nonwoven fabric. The fixed roller 8 and the movable roller 10 squeeze the nonwoven fabric to squeeze out the disinfectant solution inside the nonwoven fabric and return it to the disinfection tank 1.
[0022] A plate chain conveyor 12 is inclinedly mounted on the frame 7. The upper and lower ends of the plate chain conveyor correspond to the moving roller 10 and the limiting roller 4. The plate chain conveyor 12 includes multiple chain plates 13 connected end-to-end. Each end of a chain plate 13 is hinged with a pressure plate 14. A coil spring is installed between the pressure plate 14 and the chain plate 13. Without external interference, the spring force prevents the pressure plate 14 from contacting the chain plate 13. Vertically extending motion guide plates 16 are installed on both sides of the plate chain conveyor 12. The motion guide plates 16 extend vertically, such as... Figure 4 As shown, the two ends of the motion guide plate 16 are semi-circular.
[0023] The pressure plate 14 on the chain plate 13 above the plate chain conveyor 12 is rotated to contact the action guide plate 16, so that the pressure plate 14 presses on the plate chain. The non-woven fabric is held by the pressure plate 14 and the chain plate 13. The pressure plate 14 on the chain plate 13 near the fixed roller 8 is rotated to disengage from the action guide plate 16, so that the pressure plate 14 rotates to a vertical position and releases the non-woven fabric.
[0024] Example 2: A disinfection and sterilization device for non-woven fabric production includes a disinfection tank 1 with an opening at the top. The disinfection tank 1 is filled with disinfectant solution. A drain valve 2 is installed at the bottom of the disinfection tank 1 to drain the disinfectant solution in the disinfection tank 1. A liquid level alarm 3 is installed in the disinfection tank 1. When the remaining disinfectant solution is low, the liquid level alarm 3 will issue an alarm signal to remind the staff to add disinfectant solution.
[0025] The disinfectant solution has two limiting rollers 4 inside. The two limiting rollers 4 are identical in size and installed at the same height. A support plate 5 is installed in the disinfection pool 1 below the limiting rollers 4. The support plate 5 supports the non-woven fabric and reduces the stretching of the non-woven fabric after it is wetted. Feeding rollers 6 and extrusion units are respectively installed at both ends of the disinfection pool 1. Feeding rollers 6 guide the non-woven fabric entering the disinfection pool 1. The non-woven fabric passes over the feeding rollers 6 and passes under the limiting rollers 4.
[0026] The extrusion unit includes a frame 7, which is located at the upper end of the disinfection tank 1. A fixed roller 8 is rotatably mounted on the frame 7, and a drive motor 9 is fixedly mounted on the frame 7. The drive motor 9 is connected to the fixed roller 8 and drives the fixed roller 8 to rotate. A movable roller 10 is located diagonally above the fixed roller 8. The movable roller 10 has the same specifications as the fixed roller 8. The frame 7 is equipped with a lifting mechanism connected to the movable roller 10. The lifting mechanism includes two vertically extending electric telescopic rods 11. The upper ends of the electric telescopic rods 11 are rotatably connected to the fixed roller 8 on the same side. The lifting mechanism controls the lifting and lowering of the movable roller 10, thereby adjusting the distance between the movable roller 10 and the fixed roller 8. When the nonwoven fabric is inserted between the movable roller 10 and the fixed roller 8, the distance between the movable roller 10 and the fixed roller 8 is increased to facilitate the passage of the nonwoven fabric. Multiple anti-slip strips are evenly arranged on the outer surfaces of the fixed roller 8 and the movable roller 10 to reduce slippage. The fixed roller 8 and the movable roller 10 extrude the disinfectant solution inside the nonwoven fabric and return it to the disinfection tank 1.
[0027] A plate chain conveyor 12 is inclinedly mounted on the frame 7. The upper and lower ends of the plate chain conveyor correspond to the moving roller 10 and the limiting roller 4. The plate chain conveyor 12 includes multiple chain plates 13 connected end-to-end. Each end of a chain plate 13 is hinged to a pressure plate 14. A coil spring is installed between the pressure plate 14 and the chain plate 13. Each end of a chain plate 13 has a limiting block corresponding to the pressure plate 14 on the same side. Without external interference, the spring force and the limiting plate's positioning keep the pressure plate 14 vertical. Both sides of the plate chain conveyor 12 are vertically mounted with motion guide plates 16, which extend vertically. Figure 4 As shown, the two ends of the motion guide plate 16 are semi-circular.
[0028] The pressure plate 14 on the chain plate 13 above the plate chain conveyor 12 is rotated to contact the action guide plate 16, so that the pressure plate 14 presses on the plate chain. The non-woven fabric is held by the pressure plate 14 and the chain plate 13. The pressure plate 14 on the chain plate 13 near the fixed roller 8 is rotated to disengage from the action guide plate 16, so that the pressure plate 14 rotates to a vertical position and releases the non-woven fabric.
[0029] The specific working process is as follows: Disinfectant is added to the disinfection tank 1 to submerge the limiting roller 4. The nonwoven fabric is passed over the feed roller 6 and under the limiting roller 4, then passes over the top of the plate chain conveyor 12 and enters between the fixed roller 8 and the moving roller 10. The drive motor 9 and the plate chain conveyor 12 are started. The nonwoven fabric is wetted and disinfected by the disinfectant. Then it enters the plate chain conveyor 12 and rotates until the outer side of the pressure plate 14 on the chain plate 13 above the plate chain conveyor 12 contacts the action guide plate 16, so that the pressure plate 14 presses on the plate chain. The pressure plate 14 and the chain plate 13 hold the nonwoven fabric, reducing the stretching of the nonwoven fabric. The pressure plate 14 on the chain plate 13 near the fixed roller 8 of the plate chain conveyor disengages from the action guide plate 16, so that the pressure plate 14 rotates to a vertical position to release the nonwoven fabric. It enters between the fixed roller 8 and the moving roller 10 to squeeze out the disinfectant between the nonwoven fabric and return it to the disinfection tank 1.
