Description

Technical Field

[0001] The utility model relates to the technical field of gauze production equipment, in particular to a gauze processing oven equipment. Background Art

[0002] Gauze is a thin, breathable cotton fabric with a sparse warp and weft, typically made from pure cotton yarn. Its characteristic mesh structure allows for excellent air permeability and water absorption, making it widely used in medical and daily life applications. It also boasts fast production speeds and low costs.

[0003] During the production and processing of gauze, it needs to go through processes such as sizing, weaving, bleaching, washing, drying, and finishing. The bleaching step is to bleach the woven gauze base cloth to remove impurities and stains in the yarn, so that the gauze color is pure white. The bleached gauze needs to be dried to remove excess moisture for subsequent finishing and processing.

[0004] Currently, gauze is typically dried using hot air drying, which uses a serpentine heating tube to heat the interior of the oven, and an internal motor to drive the fan blades, allowing the hot air to heat and dry the gauze. However, when the gauze contains a lot of moisture, this drying method cannot completely remove the moisture from the gauze, and the drying process requires high power, resulting in high energy consumption.

[0013] Furthermore, two tensioning rollers corresponding to each other and with a gap between them are provided between two adjacent air guide tubes. The gap between the two tensioning rollers in the same group is used for gauze to pass through. The tensioning rollers are rotatably connected to the box body, and the rotation axis is parallel to the axis of the air guide tube.

[0014] Furthermore, both ends of the tensioning roller are provided with moving blocks, and the same end of the two tensioning rollers in the same group are rotatably connected to the same moving block, and the moving block is vertically slidably connected to the inner wall of the box.

[0015] Furthermore, a guide roller is provided inside the box body at a position corresponding to the discharge port, and the guide roller is rotatably connected to the box body for guiding the gauze.

[0019] 1. By arranging at least two sets of parallel squeezing assemblies at the feed inlet in the box, the gauze with moisture enters the box from the feed inlet and is squeezed by at least two squeezing rollers to squeeze out the moisture contained in the gauze as much as possible. In addition, along the conveying direction of the gauze, the gap between the two adjacent squeezing rollers gradually decreases, and the gauze can be squeezed at least twice with gradually increasing squeezing force, so that the internal moisture of the gauze is squeezed out as much as possible before the hot air drying, which is convenient for the subsequent drying process. At the same time, the moisture in the gauze is squeezed out in advance, which effectively reduces the energy consumption required for the subsequent drying process.

[0020] 2. By adopting the method of opening an air outlet slot on the air guide tube, hot air can be blown out from the air outlet slot of the air guide tube. The gauze is wound around the air guide tube for transportation, so that the gauze can be dried by the hot air blown out from the air outlet slot when passing through the surface of the air guide tube.

DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of this application more clear, the following will further describe the embodiments of this application in conjunction with the accompanying drawings. The following describes a preferred embodiment of the present application among multiple possible embodiments, which is intended to provide a basic understanding of the present application, but is not intended to identify the key or decisive elements of the present application or to limit the scope of protection.

[0026] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0028] In the description of this application, it should be noted that the circuits, electronic components and modules involved in this application are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to internal structures and methods.

[0029] It should be further noted that, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0030] The embodiment of the present application provides a gauze processing oven device, referring to Figure 1 The gauze processing oven equipment includes a box body 1, the interior of the box body 1 is hollow, and an air guide tube 2 for blowing and drying the gauze 3 is provided inside the box body 1. The gauze 3 is dried inside the box body 1.

[0031] A feed port 11 is formed through one side wall of the box 1, and a discharge port 12 is formed through the other side wall of the feed port 11. The gauze 3 enters the box 1 through the feed port 11 and is discharged from the discharge port 12 after drying. A guide roller 15 is provided inside the box 1 at a position corresponding to the discharge port 12. The guide rollers 15 are provided with two guide rollers 15 arranged in an upper and lower corresponding manner and spaced apart. The two guide rollers 15 are rotatably connected to the inner wall of the box 1. The gap between the guide rollers 15 allows the gauze 3 to pass through. The guide rollers 15 can provide guidance for the discharge process of the gauze 3.

[0032] The air duct 2 is horizontally and rotatably connected to the box body 1. The number of air ducts 2 can be multiple. In the embodiment of the present application, there are four air ducts 2, and the four air ducts 2 are staggered and spaced from bottom to top, and the air ducts 2 are arranged in parallel.

[0033] The air guide tubes 2, which are staggered and spaced from bottom to top, can be arranged in a serpentine manner for the gauze 3 to be transported. The gauze 3 arranged in a serpentine manner inside the housing 1 can effectively extend the transport path of the gauze 3, and in an oven of the same size, can effectively increase the drying time of the gauze 3, thereby improving the drying effect of the gauze 3.

[0034] Furthermore, the interior of the air duct 2 is hollow, and one end of the air duct 2 can be connected to an external hot air source such as a hot air blower. A plurality of air outlet slots 21 are formed through the side wall of the air duct 2. The plurality of air outlet slots 21 are spaced apart along the circumference of the air duct 2 and are connected to the interior of the air duct 2. This allows hot air to enter the air duct 2 and be blown out through each of the air outlet slots 21. Since the gauze 3 is wound around each of the air ducts 2, the hot air can be blown directly onto the gauze 3 after being blown out of the air outlet slots 21, thereby heating and drying the gauze 3.

[0035] Reference Figure 1At least two groups of extrusion assemblies 4 are provided inside the box body 1 at locations corresponding to the feed port 11. In the embodiment of the present application, three groups of extrusion assemblies 4 are provided. Each group of extrusion assemblies 4 includes two extrusion rollers 41 that are spaced apart and correspond to each other in the upper and lower directions. The three groups of extrusion assemblies 4 are spaced apart along the conveying direction of the gauze 3. All the extrusion rollers 41 are horizontally placed and rotatably connected to the inner wall of the box body 1. The gap between two extrusion rollers 41 in the same group is sufficient for the gauze 3 to pass through. In addition, the gap between the extrusion rollers 41 of two adjacent groups of extrusion assemblies 4 gradually decreases along the conveying direction of the gauze 3.

[0036] After the gauze 3 with moisture enters casing 1 inside from feed port 11, through the squeezing of at least two squeezing rollers 41, the moisture contained in gauze 3 is squeezed out as much as possible, and along gauze 3 conveying directions, the gap between adjacent two groups of squeezing rollers 41 is gradually reduced, and the squeezing process that the squeezing force is gradually increased at least twice can be carried out to gauze 3, so that gauze 3 is squeezed out internal moisture as much as possible between carrying out hot air drying, it is convenient to subsequent drying process, and the moisture in gauze 3 is squeezed out in advance simultaneously, effectively reducing the energy consumption required for subsequent drying process. In other embodiments of the present application, the quantity of squeezing assembly 4 can be increased or decreased according to actual conditions, and can satisfy that the moisture in gauze 3 is fully squeezed out.

[0037] At the same time, the feed port 11 is located below the discharge port 12, which facilitates the water in the gauze 3 to fall after being squeezed out, and also prevents the water squeezed out of the gauze 3 from falling back on the gauze 3.

[0038] Further, refer to Figure 1 To facilitate the collection of moisture squeezed out of the gauze 3, a water collecting box 5 is detachably connected to the bottom of the box body 1. The detachable connection can be made by snapping or fixing with bolts, thereby fixing the water collecting box 5 to the bottom of the box body 1. A water outlet 51 is provided on the side wall of the water collecting box 5. The water outlet 51 is located near the bottom of the water collecting box 5. The water outlet 51 can be connected to an external drainage pipe, and the water collected in the water collecting box 5 can be discharged from the water outlet 51.

[0039] Furthermore, a filter plate 13 is fixed on the top of the water collecting box 5, which separates the box body 1 from the internal space of the water collecting box 5, and a number of water filtering holes 14 are spaced apart on the filter plate 13. The water squeezed out of the gauze 3 can enter the water collecting box 5 from the water filtering holes 14, while the debris other than the water is blocked in the box body 1 by the filter plate 13 and can be cleaned separately later to avoid the debris from clogging the water outlet 51.

[0040] Reference Figure 1 and Figure 2A ventilation mesh tube 22 is coaxially sleeved outside the air guide 2. The sidewalls of the ventilation mesh tube 22 are a mesh structure that allows for ventilation. The gauze 3 is wrapped around the ventilation mesh tube 22. The ends of the ventilation mesh tube 22 are fixed to the air guide 2 so that the ventilation mesh tube 22 rotates synchronously with the air guide 2. A ventilation gap 23 is left between the ventilation mesh tube 22 and the air guide 2, and the air outlet slot 21 is connected to the ventilation gap 23.

[0041] Hot air can be blown out from the air outlet slot 21 of the air guide 2, and the gauze 3 is wound around the air guide 2 for transportation, so that the gauze 3 can be dried by the hot air blown out from the air outlet slot 21 when passing through the surface of the air guide 2. During the entire drying process, the gauze 3 is always in close contact with the surface of the air guide 2, and the hot air blown out from the air outlet slot 21 can directly act on the surface of the gauze 3, thereby reducing heat loss and improving the effect of hot air drying the gauze 3. At the same time, the hot air partially blocked by the gauze 3 can be diffused from the air gap 23, thereby strengthening the convection of the hot air and preventing the air outlet slot 21 from being blocked by the gauze 3, resulting in the hot air being suffocated in the air guide 2.

[0042] In the embodiment of the present application, the two air guide tubes 2 at the bottom can be connected to an external hot air source, while the two air guide tubes 2 at the top can be connected to an external cold air source. Thus, the gauze 3 is first dried quickly by hot air, and then cooled and dried by cold air, which can quickly reduce the temperature of the gauze 3.

[0043] Further, refer to Figure 1 and Figure 3 Two tensioning rollers 6 corresponding to each other and with a gap between them are provided between two adjacent air guide tubes 2. The gap between the two tensioning rollers 6 in the same group can allow the gauze 3 to pass through. A moving block 61 is provided at both ends of the tensioning roller 6. The same end of the two tensioning rollers 6 in the same group is rotatably connected to the same moving block 61, so that the two tensioning rollers 6 in the same group can move synchronously. The moved tensioning rollers 6 can adjust the tension of the gauze 3 during transportation.

[0044] Furthermore, a guide rail 16 is fixed to the inner wall of the housing 1 corresponding to the movable block 61. The guide rail 16 is placed vertically, and the movable block 61 is slidably connected to the guide rail 16, so that the movable block 61 can slide vertically along the guide rail 16, thereby freely adjusting the position of the movable block 61. The movable block 61 can be fixed in position relative to the guide rail 16 by inserting a stopper such as a stopper pin. There are many ways to fix the movable block 61, all of which are existing technical solutions and will not be described in detail here.

[0045] The implementation principle of the gauze processing oven equipment in the embodiment of the present application is as follows: after the gauze 3 enters the box body 1, it is first squeezed by multiple groups of squeezing rollers 41 to squeeze out the moisture in the gauze 3 as much as possible, and then the gauze 3 is serpentine-wound on the air guide tube 2, and the hot air is blown toward the surface of the gauze 3 through the air outlet slot 21 on the air guide tube 2, performing multi-stage drying treatment on the gauze 3.
