Description

Technical Field

[0001] This invention relates to the field of cotton gauze production technology, specifically a disinfection device for the production of medical cotton gauze. Background Technology

[0002] As a medical dressing, medical gauze requires extremely high cleanliness and sterility during its production process. In traditional production processes, dust removal, disinfection, and drying of gauze are mostly carried out in separate steps, resulting in dispersed equipment, large floor space, high energy consumption, and easy secondary contamination during material transfer between processes.

[0003] Existing disinfection devices are ineffective at completely removing firmly attached fine dust with simple blowing, affecting the cleanliness of the cotton gauze. Secondly, if the cotton gauze is not fully flattened or the spray is uneven during disinfection, it can easily lead to disinfection of incomplete areas. Furthermore, the spray volume cannot be adaptively adjusted according to the production line speed, potentially resulting in wasted disinfectant or insufficient spraying. Therefore, we provide a disinfection device for the production of medical cotton gauze. Summary of the Invention

[0004] The purpose of this invention is to provide a disinfection device for the production of medical cotton gauze to solve the problems mentioned in the background art.

[0005] The present invention can be achieved through the following technical solution: a disinfection device for the production of medical cotton gauze, comprising a box and a negative pressure generating device set on the top of the box, wherein the box is provided with a dust removal chamber, a liquid spraying chamber and a drying chamber that are independent of each other in sequence; The dust removal chamber is equipped with rollers for conveying and flattening cotton yarn. A base is provided below the horizontal unfolded surface of the cotton yarn. Multiple vibration components are provided on the top of the base along the conveying direction of the cotton yarn. Exhaust ports connected to the negative pressure generating device are provided on both sides of the top of the base and above the horizontal unfolded surface of the cotton yarn. Multiple rollers are installed inside the spray chamber. The cotton yarn passes around the rollers in a horizontal reciprocating S-shaped direction. Each roller has a spray assembly on the outer side of its curved surface. The spray direction of the spray assembly is perpendicular to the current curved surface of the cotton yarn. The drying chamber is equipped with multiple rollers, and the cotton yarn passes around the rollers in a vertical reciprocating S-shaped direction. The bottom of the drying chamber is equipped with a drying pipe that blows hot air upwards, and an ultraviolet lamp is installed between every two rollers.

[0006] A further technical improvement of the present invention is that: each of the vibration components includes a fixing strip fixed to the top of the base, and a plurality of fixing sleeves are linearly fixed through the top of the fixing strip. A sliding seat is slidably arranged in each fixing sleeve. A compression spring is sleeved on the outer periphery of the sliding seat and respectively abuts between the fixing sleeve and the top bearing boss of the sliding seat. A vibration ball is placed in the groove at the top of the bearing boss. A reciprocating lifting seat that can move up and down is arranged below the fixing strip. An electromagnet is provided at the bottom of the sliding seat and magnetically fixed to the reciprocating lifting seat.

[0007] A further technical improvement of the present invention is that: a crankshaft driven by a motor is rotatably arranged below the reciprocating lifting seat, a crankshaft connecting seat is rotatably sleeved on the outer circumference of the crankshaft, a connecting rod is arranged between the crankshaft connecting seat and the fixing bar, and the two ends of the connecting rod are rotatably connected to the crankshaft connecting seat and the fixing bar respectively.

[0008] A further technical improvement of the present invention is that: a through groove is provided in the sliding seat, a column extending into the through groove is fixed at the bottom of the vibrating ball, and an anti-detachment block is fixed at the bottom of the column.

[0009] A further technical improvement of the present invention is that the spraying speed of the spraying assembly includes two control modes: one is controlled by the airflow velocity, and the other is controlled by the rotational speed of the roller.

[0010] A further technical improvement of the present invention is that, in the airflow velocity control mode, the liquid spraying assembly includes a liquid storage tank and an atomizing spray strip located at the bottom of the liquid storage tank. The liquid storage tank is provided with a liquid storage cavity, and a vent pipe is provided through the middle of the liquid storage tank. One end of the vent pipe extends into the atomizing spray strip, and the other end is connected to a high-pressure air source. A capillary outlet pipe extending below the liquid surface of the liquid storage cavity is provided on the outer side of the constriction port of the vent pipe.

[0011] A further technical improvement of the present invention is that, in the roller speed control mode, the spraying assembly includes a liquid storage tank and an atomizing spray strip located at the bottom of the liquid storage tank. The liquid storage tank is provided with a liquid storage cavity, and a vent pipe is provided through the middle of the liquid storage tank. A transmission bevel gear is rotatably provided on the outside of the vent pipe. Multiple wedge-shaped protrusions are evenly provided on the top of the transmission bevel gear. A liquid outlet valve that can move up and down is provided above the wedge-shaped protrusions, thereby controlling the opening and closing state of the leakage hole at the bottom of the liquid storage tank. A transmission bevel gear meshes with one side of the transmission bevel disc, and the transmission bevel gear is connected to the corresponding roller via a transmission belt.

[0012] A further technical improvement of the present invention is that: the atomizing spray strip includes an atomizing chamber and a spraying chamber, the atomizing chamber is provided with liquid fragments, a plurality of distribution holes are provided between the atomizing chamber and the spraying chamber, and a plurality of spray holes are provided at the bottom of the spraying chamber.

[0013] A further technical improvement of the present invention is that the distribution holes are gradually densely distributed from the middle to both sides within the atomizing spray strip.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses the mechanical vibration of the vibration component to shake up the dust embedded in the cotton yarn fibers, overcoming the shortcomings of insufficient removal of attached substances by relying solely on negative pressure suction. The synergistic effect of vibration and negative pressure suction allows the dust to fall off and be immediately sucked away by the negative pressure, achieving efficient dust removal. In addition, the vibration mode, which uses electromagnet control and spring energy storage, has strong impact force and high energy utilization efficiency, achieving high-efficiency operation with low energy consumption.

[0015] 2. This invention sprays disinfectant along the normal direction by spraying it onto the curved surface of the cotton gauze on the roller of the spraying component, ensuring that the disinfectant can evenly cover every part of the curved surface without any spray dead corners; utilizing Bernoulli's principle, the high-speed airflow generates negative pressure at the converging port of the vent pipe to automatically draw in and atomize the liquid, resulting in good atomization effect, small droplets, and easy penetration into the gauze fibers.

[0016] 3. In Example 2, the wedge-shaped protrusions evenly arranged on the top of the transmission bevel gear disc cooperate with the liquid outlet valve to control the opening and closing state of the leakage hole; when the production line speed increases, the roller speed increases synchronously, driving the opening frequency of the liquid outlet valve to increase, thereby automatically increasing the amount of liquid sprayed per unit time, realizing the precise matching of the amount of liquid sprayed with the production speed, which not only ensures the disinfection effect at high speed, but also avoids the waste of liquid at low speed, and has a high degree of intelligence.

[0020] To further illustrate the technical means and effects adopted by the present invention to achieve the 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.

[0021] Example 1 Please see Figure 1 As shown, a disinfection device for the production of medical cotton gauze includes a box 1 and a negative pressure generating device 2 set on the top. The box 1 has a dust removal chamber 101, a spraying chamber 102 and a drying chamber 103 arranged from left to right. Inside the dust removal chamber 101, cotton yarn is conveyed and laid out flat by rotating rollers. An upper exhaust port 4 is provided above the horizontal unfolded surface, and a base 3 is provided below the horizontal unfolded surface. Multiple vibrating components 7 are installed in the middle of the base along the cotton yarn conveying direction, and a lower exhaust port 5 is symmetrically provided at the top edge of the base 3. Both the upper exhaust port 4 and the lower exhaust port 5 are connected to the negative pressure generating device. Specifically, such as Figures 2-3 As shown, the vibrating assembly 7 includes a fixing strip 701 fixed to the top of the base 3. Multiple fixing sleeves 702 are linearly arrayed and fixed through the fixing strip 701. A sliding seat 703 is slidably installed in each fixing sleeve 702. The top of the sliding seat 703 is provided with a bearing boss for bearing the vibrating ball 705. A compression spring 704 is sleeved on the outer periphery of the sliding seat 703. The two ends of the compression spring 704 abut against the bearing boss and the fixing sleeve 702 respectively. A pressure sensor is attached to the bottom of the bearing boss. The pressure sensor is used to collect pressure data and convert it into the on / off state of the electromagnet fixed to the bottom of the sliding seat 703. The sliding seat 703 is provided with a through groove, the top of the bearing boss is provided with a groove, the vibrating ball 705 is placed in the groove, the bottom of the vibrating ball 705 is fixed with a column 706, the column 706 extends into the through groove, the bottom of the column 706 is fixed with an anti-detachment block 707, the presence of the anti-detachment block 707 prevents the column 706 from completely detaching from the through groove. A reciprocating lifting seat 708 is provided below the fixing bar 701. The bottoms of multiple sliding seats 703 are magnetically fixed to the reciprocating lifting seat 708 by electromagnets. A crankshaft 711 driven by a motor is rotatably installed below the fixing bar 701. A crankshaft connecting seat 710 is rotatably sleeved on the outer circumference of the crankshaft 711. A connecting rod 709 is provided between the crankshaft connecting seat 710 and the fixing bar 701. The two ends of the connecting rod 709 are rotatably connected to the crankshaft connecting seat 710 and the fixing bar 701, respectively.

[0022] After being processed by the vibration component 7, the cotton yarn is conveyed into the spray chamber 102 and wound by multiple rollers 6 to form a horizontal reciprocating "S" shape. A spray component 9 is provided on the outer side of the curved surface of each roller 6 that contacts the cotton yarn. The spray component 9 is installed on the outer side of the roller 6 at a fixed angle by the mounting bracket 8, and the spray path of the spray component 9 is the normal direction of the corresponding curved surface. like Figures 4-5 As shown, the spray assembly 9 includes a liquid storage tank 901 and an atomizing spray strip 904 fixedly installed at its bottom. The liquid storage tank 901 has a liquid storage chamber 902 inside. A vent pipe 903 is installed through the middle of the liquid storage tank 901. One end of the vent pipe 903 extends and connects to the atomizing spray strip 904. The bottom of the vent pipe 903 has an opening at the constriction position. A connecting sleeve 906 is fixed on its outer side. The side wall of the connecting sleeve 906 has a flow channel hole that communicates with the opening. A homogenizing sleeve 907 is fixedly fitted on the outside of the connecting sleeve 906. The inner side wall of the homogenizing sleeve 907 has a homogenizing groove. The outer side wall of the homogenizing sleeve 907 has several liquid inlet holes. Each liquid inlet hole is connected to a capillary outlet pipe 905. The other end of the capillary outlet pipe 905 extends into the liquid storage chamber 902 and is below the surface of the disinfectant liquid. The atomizing spray strip 904 includes an atomizing chamber 9041 and a spray chamber 9042. A fragmented liquid block 9044 is fixed in the middle of the atomizing chamber 9041. The fragmented liquid block 9044 is located directly below the converging opening of the vent pipe 903. Several distribution holes 9043 are provided between the atomizing chamber 9041 and the spray chamber 9042. The distribution holes 9043 are gradually densely distributed from the middle to both sides. Several spray holes are evenly provided at the bottom of the spray chamber 9042, so that the spray path is perpendicular to the current curved surface position.

[0023] After being sprayed with disinfectant by multiple spray components 9 on both sides of the cotton gauze, the sprayed cotton gauze enters the drying chamber 103. Several rollers 6 are rotatably installed in the drying chamber 103, and the cotton gauze passes around the rollers 6 in a vertical reciprocating "S" shape. A drying pipe 10 is set at the bottom of the drying chamber 103, which blows dry hot air vertically upward to dry the cotton gauze and exhausts the humid air from the top of the chamber. In addition, an ultraviolet lamp 11 is installed between every two rollers to disinfect and sterilize the surface of the cotton gauze. After being disinfected and dried, the cotton gauze is output from the box 1, completing the entire disinfection process.

[0024] In use, the cotton yarn is introduced into the dust removal chamber 101 and then flattened and conveyed by multiple rollers 6. The corresponding exhaust port and motor are opened, and the motor drives the crankshaft 711 to rotate. As a result, the crankshaft connecting seat 710 and the connecting rod 709 on the crankshaft drive the reciprocating lifting seat 708 to move up and down. When the reciprocating lifting seat 708 moves downward, it pulls the sliding seat 703 fixed to it downward and compresses the compression spring 704. When the pressure of the compression spring 704 on the bearing boss reaches a certain value, the electromagnet is disconnected, so that the sliding seat 703 is released from the reciprocating lifting seat 708. Under the action of the compression spring 704, the sliding seat 703 transfers its potential energy. The energy is converted into kinetic energy, which is quickly bounced upwards to contact and vibrate the bottom surface of the cotton gauze. Specifically, at the end of the spring-constrained bounce of the sliding seat 703, the vibrating ball 705 leaves the groove under inertia and vibrates upwards to the bottom of the cotton gauze, causing the dust attached to it to fall off or be lifted up, and then discharged from the exhaust port by the negative pressure airflow. By controlling the crankshaft speed, when the crankshaft rotates to the highest point, the electromagnet is controlled to magnetically fix the reciprocating lifting seat 708 and the bottom of the sliding seat 703 again, and the vibrating ball 705 also re-enters the groove to enter the next stage of the energy accumulation process. This process is repeated to continuously vibrate and remove dust from the cotton gauze. When the cotton gauze enters the spray chamber 102, high-pressure, high-speed gas is introduced into the vent pipe 903 in each spray component 9. When the high-pressure, high-speed airflow passes through the converging port, it generates the Bernoulli effect, thereby drawing out the disinfectant from the storage chamber 902 through the capillary outlet pipe 905. The disinfectant enters the homogenizing sleeve 907, and then enters the vent pipe 903 through the connecting sleeve 906. It is then carried by the high-pressure, high-speed airflow into the atomizing chamber 9041. The airflow carries droplets that collide with the broken liquid block 9044 and atomizes them, spreading them to both sides. Then, it enters the spray chamber 9042 evenly through the distribution hole 9043 and is discharged, spraying onto the corresponding surface of the cotton gauze. The amount of liquid output is completely controlled by the airflow velocity. The drying chamber 103 performs heat drying and ultraviolet sterilization, completing the entire disinfection process.

[0025] Example 2 In Embodiment 1, the amount of liquid output from the spray assembly 9 is controlled by airflow. However, this is difficult to adaptively adjust when the cotton yarn conveying speed is uneven. Therefore, in this embodiment: Figures 6-7 As shown, a transmission bevel gear disk 909 is rotatably arranged on the outside of the vent pipe 903. Multiple wedge-shaped protrusions 910 are evenly arranged on the top of the transmission bevel gear disk 909. A liquid outlet valve 912 is arranged on the top of the wedge-shaped protrusions 910. The bottom of the liquid outlet valve 912 maintains rolling contact with the top of the transmission bevel gear disk 909 through ball bearings. A liquid outlet channel is arranged on one side of the liquid storage valve 912 and is connected to the homogenization sleeve 907 through a connecting liquid outlet pipe 911. A leakage hole is provided at the bottom of the liquid storage tank 901. The top of the liquid outlet valve 912 controls the opening and closing of the leakage hole. A transmission bevel gear 908 is meshed and driven on one side of the transmission bevel gear disc 908. The transmission bevel gear 908 is coaxially fixed with the transmission pulley rotatably located on one side of the liquid storage tank 901 via the transmission shaft. The transmission pulley is connected to the corresponding roller 6 by synchronous belt drive. When roller 6 rotates, it drives the transmission bevel gear disk 909 to rotate through the synchronous belt and gear transmission structure. As a result, the wedge-shaped protrusions 910 evenly arranged on its top intermittently lift the liquid storage valve 912. When the liquid storage valve 912 is lifted, it blocks the leakage hole, preventing liquid from flowing out. Under normal conditions, the liquid storage valve 912 will move downward due to the pressure of the disinfection hydraulic pressure and its own gravity, causing the leakage hole to open and allowing liquid to flow out. The faster the roller 6 conveys the cotton yarn, the higher the frequency of liquid flow, thus realizing adaptive liquid spraying operation according to the cotton yarn conveying speed.
