Description
Technical Field
[0001] This utility model relates to the technical field of nonwoven wiping cloth production equipment, specifically to a flame retardant spraying device for flame-retardant nonwoven wiping cloth. Background Technology
[0002] In the production process of nonwoven wiping cloths, flame retardant coating is usually required to impart flame retardant properties. An existing patent, CN204074326U, describes a nonwoven cloth coating device, which includes a gun body and a colorant cylinder. The colorant cylinder is sequentially connected to a main channel, a secondary channel, a nozzle interface, and a nozzle. The secondary channel includes a first channel, a second channel, and a third channel. The nozzle interface includes a fixed nozzle interface and a movable nozzle interface. The first and third channels are connected to the movable nozzle interface, and the second channel is connected to the fixed nozzle interface. The nozzles are equipped with nozzle sleeves, effectively improving work efficiency. By selecting different nozzles for spraying, different objects can be sprayed. The nozzle sleeves prevent debris from entering the channels, ensuring unobstructed flow. This invention is simple, ingenious, and low-cost, making it worthy of widespread use.
[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: during the spraying process, some flame retardant will be sprayed outside the non-woven fabric, resulting in waste of flame retardant. At the same time, it is necessary to clean up the excess flame retardant, which increases production costs and production time. Therefore, we propose a flame retardant spraying device for flame-retardant non-woven wiping cloth to solve the above-mentioned problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a flame retardant spraying device for flame-retardant nonwoven wiping cloths. This device solves the problem that in existing spraying processes, some flame retardant is sprayed outside the nonwoven cloth, resulting in waste of flame retardant. In addition, it requires cleaning up excess flame retardant, which increases production costs and time.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a flame retardant spraying device for flame retardant nonwoven wiping cloth, including a workbench, a guide rail mechanism is fixedly connected to the outside of the workbench, the guide rail mechanism is arranged horizontally, and there are two guide rail mechanisms in total;
[0006] The two guide rail mechanisms are fixedly connected to the front and rear sides of the worktable in opposite directions. Both guide rail mechanisms have transverse grooves inside. A horizontally arranged unfolding push rod is fixedly connected inside the transverse groove. A moving component is installed on the output end of the unfolding push rod. A connecting bracket is fixedly connected to the outside of the moving component. A supply pipe for supplying materials is fixedly connected to the top surface of the transverse component in the connecting bracket. A nozzle assembly is fixedly connected in a linear array on the bottom surface of the connecting bracket.
[0007] Preferably, the nozzle assembly is connected to the supply pipe, and a residual material collection pipe is fixedly connected to the bottom surface of the worktable, and the residual material collection pipe is connected to the worktable.
[0008] Preferably, the workbench has a frustum-shaped structure that is thicker at the top and thinner at the bottom, and a support leg assembly is fixedly connected to the bottom surface of the workbench, with the support leg assembly being arranged longitudinally.
[0009] Preferably, the support leg assembly has four locations, and the four support leg assemblies are respectively fixedly connected to the four corners of the bottom surface of the workbench. The bottom of the four support leg assemblies is also fixedly connected to a support assembly.
[0010] Preferably, the support component is a rectangular frame structure, and a notch is provided at the top of the worktable, with a driven guide roller rotatably connected inside the notch.
[0011] Preferably, there are four driven guide rollers, with each pair of longitudinally adjacent driven guide rollers forming a group. A servo motor is installed at the front end of the worktable, and the rear output shaft of the servo motor is connected to the driven guide roller. A fabric assembly passes through the interior of the driven guide roller.
[0012] Preferably, a filter plate assembly is fixedly connected to the inner side of the workbench, and the filter plate assembly has filter holes arranged in a rectangular array inside.
[0013] Beneficial effects
[0014] This invention provides a flame retardant spraying device for flame-retardant nonwoven wiping cloths. Compared with the prior art, it has the following advantages:
[0015] The flame retardant spraying device for this flame-retardant nonwoven wiping cloth, through the linkage structure of the guide rail mechanism, unfolding push rod and spray pipe assembly, can flexibly adjust the spraying range according to the width of the cloth assembly, avoiding the edge spraying blind spots or over-spraying problems caused by changes in the width of the cloth in traditional fixed spraying devices. At the same time, the design of the truncated cone-shaped worktable and the waste material collection pipe allows the dripping flame retardant to be automatically collected and recycled. Compared with the existing technology of directly discarding or additional cleaning, it significantly reduces the waste of flame retardant, lowers production costs, and simplifies the subsequent cleaning process.
[0016] This flame retardant spraying device for flame-retardant nonwoven wiping cloth uses a servo motor to drive the driven guide roller, which in turn drives the cloth assembly to move at a constant speed. Combined with the uniform atomization spraying of the spray nozzle assembly, it achieves uniform adhesion of the flame retardant to the cloth surface. This solves the problem of uneven spraying caused by manual feeding or unstable rotation speed in existing technologies. In addition, the filter plate assembly and filter hole assembly can filter impurities in the flame retardant in real time, avoid spray nozzle blockage, and ensure continuous and stable spraying process. Compared with traditional devices without a filtration structure, it further improves product quality and production efficiency. Attached Figure Description

[0024] 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.
[0025] Please see Figures 1-6 This utility model provides a technical solution: a flame retardant spraying device for flame retardant non-woven wiping cloth, including a workbench 1, a guide rail mechanism 3 fixedly connected to the outside of the workbench 1, the guide rail mechanism 3 is arranged horizontally, and there are two guide rail mechanisms 3 in total.
[0026] Two guide rail mechanisms 3 are fixedly connected to the front and rear sides of the workbench 1 in opposite directions. Both guide rail mechanisms 3 have transverse grooves inside. A horizontally arranged unfolding push rod 301 is fixedly connected inside the transverse groove. A moving component 3011 is installed on the output end of the unfolding push rod 301. A connecting bracket 3012 is fixedly connected to the outside of the moving component 3011. A supply pipe 3013 for supplying materials is fixedly connected to the top surface of the transverse component in the connecting bracket 3012. A nozzle assembly 3014 is fixedly connected in a linear array on the bottom surface of the connecting bracket 3012.
[0027] Two transverse guide rail mechanisms 3 are set on the outside of the workbench 1. The unfolding push rod 301 in the guide rail mechanism 3 is connected to the connecting bracket 3012 with the supply pipe 3013 and the spray nozzle assembly 3014 through the moving component 3011. By adjusting the position of the output end of the unfolding push rod 301, the moving component 3011 and the spray nozzle assembly 3014 can be moved laterally, so that the spraying range of the spray nozzle assembly 3014 can be adapted to the cloth assembly 2011 of different widths, ensuring that the flame retardant evenly covers the entire width of the cloth assembly 2011 and avoiding blind spots caused by changes in the width of the cloth.
[0028] See Figures 1-3 The nozzle assembly 3014 is connected to the supply pipe 3013, and the residual material collection pipe 101 is fixedly connected to the bottom surface of the worktable 1, and the residual material collection pipe 101 is connected to the worktable 1.
[0029] By connecting the nozzle assembly 3014 with the supply pipe 3013, the flame retardant in the supply pipe 3013 can be transported to the nozzle assembly 3014 for spraying. An excess material collection pipe 101 connected to the workbench 1 is provided at the bottom of the workbench 1. Excess flame retardant dripping during the spraying process can be collected on the surface of the workbench 1 and collected in the excess material collection pipe 101, so as to realize the recovery of flame retardant that is not attached to the cloth assembly 2011, reduce waste and simplify the subsequent cleaning process.
[0030] See Figures 2-4 The workbench 1 has a frustum-shaped structure that is thicker at the top and thinner at the bottom, and a support leg assembly 1011 is fixedly connected to the bottom surface of the workbench 1. The support leg assembly 1011 is arranged longitudinally.
[0031] The workbench 1 adopts a frustoconical structure that is thicker at the top and thinner at the bottom, with the bottom end connected to the longitudinal support leg assembly 1011. The frustoconical structure can guide the dripping flame retardant to flow along the inclined surface of the workbench 1 towards the center, making it easy for the residual material collection pipe 101 to collect it centrally. The longitudinal setting of the support leg assembly 1011 provides vertical support to the workbench 1, ensuring the overall structural stability of the device and avoiding the impact of shaking on the spraying accuracy during the spraying process.
[0032] See Figures 5-6The support leg assembly 1011 has four parts, and the four support leg assemblies 1011 are fixedly connected to the four corners of the bottom surface of the workbench 1. The bottom of the four support leg assemblies 1011 is also fixedly connected to the support assembly 1012.
[0033] The four support legs 1011 are fixed to the four corners of the bottom surface of the workbench 1, and the bottom is connected to the support component 1012 of the rectangular frame structure. The support component 1012 increases the contact area between the device and the ground, distributes the weight of the workbench 1, and further improves the stability of the device when it is placed, preventing tilting or shaking caused by unstable center of gravity. It is especially suitable for long-term continuous spraying operations.
[0034] See Figures 1-3 The support component 1012 has a rectangular frame structure, and the top of the worktable 1 has a notch, and the driven guide roller 2 is rotatably connected inside the notch.
[0035] The driven guide roller 2 is rotatably connected to the slot at the top of the workbench 1. The support component 1012 has a rectangular frame structure. The driven guide roller 2 can support and guide the fabric component 2011. Under the guidance of the driven guide roller 2, the fabric component 2011 remains flat as it passes through the spraying area, avoiding uneven spraying caused by fabric wrinkles or deviation. At the same time, the rectangular frame structure of the support component 1012 provides a stable foundation for the installation of the driven guide roller 2.
[0036] See Figures 2-5 There are four driven guide rollers 2 in total, with each pair of longitudinally adjacent driven guide rollers 2 forming a group. A servo motor 201 is installed at the front end of the worktable 1. The rear output shaft of the servo motor 201 is connected to the driven guide roller 2, and a fabric assembly 2011 passes through the inside of the driven guide roller 2.
[0037] Four driven guide rollers 2 are arranged in pairs longitudinally adjacent to each other. The front servo motor 201 is connected to the driven guide rollers 2 through the rear output shaft, driving the driven guide rollers 2 to rotate and drive the fabric assembly 2011 to move at a constant speed. The precise speed control of the servo motor 201 can ensure that the fabric assembly 2011 passes under the spray nozzle assembly 3014 at a constant speed. With the stable spray amount of the spray nozzle assembly 3014, the flame retardant is evenly adhered to the fabric assembly 2011, improving the efficiency of automated continuous production.
[0038] See Figures 1-3 A filter plate assembly 2012 is fixedly connected to the inner side of the workbench 1. The filter plate assembly 2012 has a filter hole assembly 2013 arranged in a rectangular array inside.
[0039] The filter plate assembly 2012 is fixed inside the workbench 1. The filter plate assembly 2012 has a rectangular array of filter holes 2013 inside. During the spraying process, the filter holes 2013 can filter impurities (such as fabric fibers, equipment debris, etc.) that may be mixed into the flame retardant, preventing impurities from entering the spray nozzle assembly 3014 and causing blockage, ensuring the purity of the flame retardant and the unobstructed spraying channel, thereby ensuring the stability of the spraying process and the spraying quality.
[0040] During operation, the fabric assembly 2011 enters from the front end of the worktable 1, passes through the driven guide roller 2 in the top notch, and the four driven guide rollers 2 are divided into two groups (each two longitudinally adjacent to each other form a group). The front servo motor 201 drives the driven guide roller 2 to rotate through the rear output shaft, causing the fabric assembly 2011 to move at a constant speed in the horizontal direction. The rotation of the driven guide roller 2 supports the fabric assembly 2011 and keeps it flat, avoiding wrinkles that may affect the spraying effect.
[0041] When it is necessary to adapt to fabric components 2011 of different widths, the push rod 301 (which is horizontally set in the horizontal groove of the guide rail mechanism 3) is activated, and its output end pushes the moving component 3011 to move horizontally along the guide rail mechanism 3, thereby driving the connecting bracket 3012, the supply pipe 3013 and the spray nozzle assembly 3014 to adjust their positions horizontally in sync, so that the spraying area of the spray nozzle assembly 3014 covers the full width of the fabric component 2011.
[0042] The supply pipe 3013 is connected to an external flame retardant supply source to deliver the flame retardant to the nozzle assembly 3014 at the bottom of the connecting bracket 3012. The nozzle assembly 3014 is arranged in a linear array to spray the flame retardant onto the fabric assembly 2011 below in a uniform atomized state.
[0043] During the spraying process, flame retardant that does not adhere to the fabric assembly 2011 drips onto the surface of the workbench 1. Since the workbench 1 has a truncated cone-shaped structure that is thicker at the top and thinner at the bottom, the dripping flame retardant converges along the inclined surface to the residual material collection pipe 101 at the bottom of the workbench 1. The residual material collection pipe 101 is connected to the workbench 1, guiding the excess flame retardant to the recycling system for recycling. The filter plate assembly 2012 fixed inside the workbench 1 and its internal rectangular array filter hole assembly 2013 can intercept impurities in the flame retardant (such as fabric fibers, equipment debris, etc.), preventing impurities from entering the spray pipe assembly 3014 and causing blockage, thus ensuring that the spraying channel is unobstructed. The workbench 1 is supported by the four corner support leg assemblies 1011. The rectangular frame structure support assembly 1012 at the bottom of the support leg assembly 1011 increases the contact area with the ground, ensuring that the device is stable and does not shake during the spraying process.
[0044] In summary, this device, by providing a driven guide roller 2, can guide the fabric assembly 2011.
[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
