Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flexible film processing nozzle technology, and in particular relates to a surface treatment nozzle for flexible film processing. Background Technology
[0002] In the processing of flexible membrane materials, surface treatment is a key step to improve its performance and applicability, which includes processes such as coating, cleaning and decontamination, and modification and activation. Among them, the surface treatment nozzle, as the core execution component, directly affects the spray pattern, coverage uniformity and accuracy of the treatment medium, and plays a decisive role in the final quality of the flexible membrane. Traditional nozzles are often fixed with simple bolts. However, under prolonged high-pressure spraying and equipment vibration, the bolts are prone to loosening, leading to leaks in the connection between the nozzle and the pipeline. This requires workers to retighten the bolts. Therefore, simple bolt fixing is not a long-term and stable solution for fixing nozzles, which increases the workload of workers and reduces overall production efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a surface treatment nozzle for flexible film processing. A fastening mechanism is implemented, specifically by pushing up the locking ring, aligning the fastening block with the bottom of the long vertical groove, and then pushing it upwards. After the fastening block enters the arc-shaped groove, it is rotated left to the end. After loosening, the fastening block enters the short vertical groove. The locking ring is then rotated clockwise to move it downwards until the limiting protrusion contacts the top of the limiting ring, completing the fixation. When changing the nozzle, the locking ring is rotated counterclockwise until the limiting protrusion contacts the bottom of the mounting tube, and the nozzle is pushed up until the fastening block enters the arc-shaped groove. It is then rotated right until it cannot be rotated further, and after loosening, the fastening block enters the long vertical groove. This design, with the fastening block entering the short vertical groove, integrates the nozzle and the delivery tube. The connection between the two is further strengthened by rotating the locking ring, effectively reducing leakage caused by nozzle loosening. This solves the problem that traditional nozzle connections rely on bolts for fixing, but these bolts are prone to loosening under prolonged high pressure and vibration, leading to increased maintenance workload and reduced work efficiency.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a surface treatment nozzle for flexible film processing, comprising an installation tube, a conveying tube fixedly connected to the bottom of the installation tube, and a nozzle inserted into the bottom of the conveying tube, and further comprising: A fastening mechanism, located below the mounting pipe, is used to securely connect the nozzle and the delivery pipe; and A replacement mechanism is located on the outside of the mounting tube and is used for quickly replacing different nozzles.
[0005] Furthermore, a sealing ring is installed on the inner wall of the nozzle, and two symmetrically arranged fastening blocks are fixedly connected to the inner wall of the nozzle. The outer surface of the nozzle is provided with threads, and the sealing ring is made of rubber.
[0006] Furthermore, the replacement mechanism includes a turntable, which is cross-shaped. Placement rings are fixedly connected to each of the four corners of the turntable. A fixed post is rotatably connected inside the turntable. Two anti-drop rings are fixedly connected to the bottom of the outer surface of the fixed post. The sides of the two anti-drop rings that are close to each other abut against the top and bottom of the turntable, respectively.
[0007] Furthermore, a limiting ring is fixedly connected to the outer surface of the conveying pipe, and a sealing groove is formed on the outer surface of the conveying pipe, with the sealing ring and the sealing groove being adapted to each other.
[0008] Furthermore, the front and back surfaces of the conveying pipe are provided with long vertical grooves, arc-shaped grooves and short vertical grooves, which are interconnected. The arc-shaped grooves are arc-shaped, and the short vertical grooves are shorter than the long vertical grooves.
[0009] Furthermore, the width of the fastening block is the same as the width of the long vertical groove and the short vertical groove. A locking ring is provided on the outer side of the nozzle. The inner wall of the locking ring is provided with threads. A limiting protrusion is fixedly connected to the top of the locking ring. The locking ring slides and limits the outer surface of the delivery pipe through the top limiting protrusion. The locking ring is threadedly connected to the outer surface of the nozzle through the threads on the inner wall.
[0010] Furthermore, the three inner rings of the placement rings are respectively provided with atomizing nozzles, linear nozzles and fan-shaped nozzles. The parts connected to the inner walls of the atomizing nozzles, linear nozzles and fan-shaped nozzles are the same. A fixing block is fixedly connected to the outer surface of the fixing column. The end of the fixing block away from the fixing column is fixedly connected to the outer surface of the mounting tube.
[0011] This utility model has the following beneficial effects: 1. This utility model features a fastening mechanism. Specifically, by pushing up the locking ring, aligning the fastening block with the bottom of the long vertical groove, and then pushing it up, the fastening block enters the arc-shaped groove and is rotated to the left to the end. After loosening, the fastening block enters the short vertical groove. The locking ring is then rotated clockwise to move it down until the limiting protrusion contacts the top of the limiting ring, thus completing the fixation. When changing the nozzle, the locking ring is rotated counterclockwise until the limiting protrusion contacts the bottom of the mounting tube. The nozzle is then pushed up until the fastening block enters the arc-shaped groove, and then rotated to the right until it cannot be rotated further. After loosening, the fastening block enters the long vertical groove. This design, by having the fastening block enter the short vertical groove, makes the nozzle and the delivery tube form a whole. The connection between the two is further stabilized by rotating the locking ring, effectively reducing leakage caused by loosening of the nozzle.
[0012] 2. This utility model features a replacement mechanism, specifically a rotary table that allows for nozzle switching. The atomizing nozzle atomizes and discharges the liquid, the linear nozzle discharges a finer liquid, and the fan-shaped nozzle expands the liquid diffusion area. Since the nozzle diameter is the same as the placement ring diameter, the placement ring can stably support the threads on the outer surface of the nozzle, preventing the nozzle from falling off. This design allows for quick and flexible replacement of different nozzles, greatly improving production efficiency.

Detailed Implementation
[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-6 As shown, this utility model is a surface treatment nozzle for flexible film processing, including a mounting tube 1, a conveying tube 22 fixedly connected to the bottom of the mounting tube 1, a nozzle 21 inserted into the bottom of the conveying tube 22, and further including: Fastening mechanism 2, located below the mounting pipe 1, is used to ensure a more secure connection between the nozzle 21 and the delivery pipe 22; and Replacement mechanism 3 is located on the outside of the installation tube 1 and is used to quickly replace different nozzles.
[0019] A sealing ring 211 is installed on the inner wall of the nozzle 21. Two symmetrically arranged fastening blocks 212 are fixedly connected to the inner wall of the nozzle 21. The outer surface of the nozzle 21 is threaded. The sealing ring 211 is made of rubber.
[0020] The replacement mechanism 3 includes a turntable 31, which is cross-shaped. Placement rings 311 are fixedly connected to the four corners of the turntable 31. A fixed post 32 is rotatably connected inside the turntable 31. Two anti-drop rings 321 are fixedly connected to the bottom of the outer surface of the fixed post 32. The sides of the two anti-drop rings 321 that are close to each other abut against the top and bottom of the turntable 31, respectively.
[0021] A limiting ring 221 is fixedly connected to the outer surface of the conveying pipe 22, and a sealing groove 222 is opened on the outer surface of the conveying pipe 22. The sealing ring 211 is adapted to the sealing groove 222.
[0022] The front and back surfaces of the conveying pipe 22 are provided with a long vertical groove 223, an arc-shaped groove 224 and a short vertical groove 225. The long vertical groove 223, the arc-shaped groove 224 and the short vertical groove 225 are interconnected. The arc-shaped groove 224 is arc-shaped and the short vertical groove 225 is shorter than the long vertical groove 223.
[0023] The width of the fastening block 212 is the same as the width of the long vertical groove 223 and the short vertical groove 225. A locking ring 23 is provided on the outer side of the nozzle 21. The inner wall of the locking ring 23 is threaded. A limiting protrusion 231 is fixedly connected to the top of the locking ring 23. The locking ring 23 slides and limits the outer surface of the delivery pipe 22 through the top limiting protrusion 231. The locking ring 23 is threadedly connected to the outer surface of the nozzle 21 through the thread on the inner wall. Push the locking ring 23 up, align the fastening block 212 with the bottom of the long vertical groove 223, and push it up. After the fastening block 212 enters the arc-shaped groove 224, it turns left to the end. After releasing, the fastening block 212 enters the short vertical groove 225. The vertical groove 225 is rotated clockwise to move the locking ring 23 downwards until the limiting protrusion 231 contacts the top of the limiting ring 221, thus completing the fixation. When changing the nozzle, the locking ring 23 is rotated counterclockwise until the limiting protrusion 231 contacts the bottom of the mounting tube 1. The nozzle 21 is pushed up until the fastening block 212 enters the arc groove 224. It is then turned right until it cannot be rotated. After loosening, the fastening block 212 enters the long vertical groove 223. This setting allows the fastening block 212 to enter the short vertical groove 225, making the nozzle 21 and the delivery tube 22 a whole. The connection between the two is made more stable by rotating the locking ring 23, which can effectively reduce leakage caused by loosening of the nozzle.
[0024] The inner rings of the three placement rings 311 are respectively equipped with atomizing nozzles 33, linear nozzles 34, and fan-shaped nozzles 35. The parts connected to the inner walls of the atomizing nozzles 33, linear nozzles 34, and fan-shaped nozzles 35 are the same. A fixing block 322 is fixedly connected to the outer surface of the fixing post 32. The end of the fixing block 322 away from the fixing post 32 is fixedly connected to the outer surface of the mounting tube 1. Rotating the turntable 31 can switch the nozzles. The atomizing nozzle 33 atomizes and discharges the liquid, the linear nozzle 34 discharges a finer liquid, and the fan-shaped nozzle 35 expands the liquid diffusion area. The diameter of the nozzle is the same as the diameter of the placement rings 311. Therefore, the placement rings 311 can stably support the threads on the outer surface of the nozzles and prevent the nozzles from falling off. This setting allows for quick and flexible replacement of different nozzles, which greatly improves production efficiency.
[0025] A specific application of this embodiment is as follows: In use, first connect the installation pipe 1 to the external conveying device. Then, according to usage requirements, rotate the required nozzle to the bottom of the conveying pipe 22. At this time, push the locking ring 23 upwards. Then, align the two fastening blocks 212 on the inner wall of the nozzle 21 with the bottom of the two long vertical grooves 223 on the outer surface of the conveying pipe 22. After alignment, push the nozzle 21 upwards, and the two fastening blocks 212 will move upwards accordingly. When the fastening blocks 212 enter the arc-shaped groove 224, rotate the nozzle 21 to the left. When the fastening blocks 212 rotate to the end of the arc-shaped groove 224 away from the long vertical grooves 223, release the nozzle 21. At this time, the two fastening blocks 212 will enter the short... Inside the vertical groove 225, the nozzle 21 can only move vertically and cannot move horizontally. At the same time, the sealing ring 211 on the inner wall of the nozzle 21 enters the sealing groove 222 on the outer surface of the delivery pipe 22. At this time, the locking ring 23 is released and rotated clockwise. Since the locking ring 23 is connected to the thread on the outer surface of the nozzle 21 through the inner wall thread, and the nozzle 21 cannot move horizontally because the two fastening blocks 212 on the inner wall are in the short vertical groove 225, the locking ring 23 will move downward when rotated clockwise. When the limiting protrusion 231 at the top of the locking ring 23 contacts the top of the limiting ring 221, the locking ring 23 cannot continue to move downward. At this time, the locking ring 23 is firmly fixed to the nozzle 21. When it is necessary to replace other nozzles, the locking ring 23 can be rotated counterclockwise. When the limiting protrusion 231 contacts the bottom of the mounting tube 1, the locking ring 23 loses contact with the nozzle 21. At this time, the nozzle 21 is no longer fixed, and the nozzle 21 can be moved upward. When the two fastening blocks 212 encounter resistance while moving upward, they have entered the arc groove 224. At this time, rotate the nozzle 21 to the right until it can no longer be rotated. Then, release the nozzle 21, and the two fastening blocks 212 will enter the long vertical groove 223. When the threads on the outer surface of the nozzle 21 are aligned with the top of the placement ring 311... When in contact, the nozzle 21 has been removed. At this time, the turntable 31 can be rotated clockwise or counterclockwise as needed. The several holes at the bottom of the atomizing nozzle 33 can produce an atomization effect when the liquid injected into the installation pipe 1 and the delivery pipe 22 is discharged. The diameter of the bottom hole of the linear nozzle 34 is smaller than that of the nozzle 21, which can make the diameter of the discharged liquid finer. The fan-shaped nozzle 35 can make the diffusion area of the discharged liquid larger. When the turntable 31 is rotated, the two anti-drop rings 321 at the bottom of the fixing column 32 can prevent the turntable 31 from falling.
