Abstract
Description
Technical Field
[0001] This invention belongs to the field of aerosol processing equipment, specifically relating to an automatic tube feeding device for omnidirectional and multi-point alignment of the hose of an atomizing nozzle. Background Technology
[0002] A sprayer is a tool or device that disperses liquid (or partially atomizable solids) into fine droplets (or particles) through specific units and sprays them evenly onto a target area in a mist form. Its core function is to convert liquid substances into an aerosol state (microscopic suspended particles), thereby improving efficiency (such as coverage area, adhesion, etc.) or meeting specific scenario requirements (such as disinfection, dust suppression, and pesticide application). A common example is a perfume spray nozzle, which includes a perfume pump, a press cap, and an outer cap. The press cap includes a bottle cap and a pressure cap with a spray channel. The spray channel is connected to the outlet tube of the perfume pump. When the pressure cap is pressed down, the liquid inside the perfume pump is compressed and sprayed out from the outlet tube and spray channel, thus completing the perfume spraying. Specifically, the length of the spray tube (hose) is cut according to usage needs. However, during the assembly process of the spray tube (hose), due to the deformation and difficulty in repositioning of the spray tube (hose), the following insertion defects exist:
[0003] 1) During production or transportation, the spray tube (hose) is inevitably squeezed, so there is a high probability that it will be deformed (that is, the hose may be in various working conditions, such as no deformation, small deformation, or large deformation). In the actual assembly process, since concentric insertion is required, once the tube opening is deformed, the insertion will fail. When this happens, manual intervention is required. The hose is pulled out, the deformed part is cut off, and then it is reinserted into the corresponding channel before continuous processing can continue. The probability of compression deformation is the frequency of manual intervention. Not only does it require high-frequency manual operation by operators, but there is also a probability that nozzles with missing tubes will flow into the market, which causes great confusion or bottleneck for enterprise processing.
[0004] 2) Due to the characteristics of hoses, conventional hose delivery generally does not use clamping, because clamping would increase the deformation rate of the hose. Therefore, hose compensation is mainly carried out by friction. If the actual hose delivery stroke is not equal to the hose compensation length (or when the hose and the hose delivery device move relative to each other), it will cause the hose assembly to be of different lengths, that is, reduce the product qualification rate. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an improved automatic tube feeding device for atomizing nozzle with omnidirectional and multi-point alignment.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0007] An automatic hose feeding device for atomizing nozzles with omnidirectional and multi-point alignment includes a sleeve with an internal hose feeding channel, a hose feeding power unit located below the sleeve to feed the hose upward into the hose feeding channel, and multiple sets of first shaping elements formed on the inner wall of the sleeve. These sets of first shaping elements are spaced apart along the length of the sleeve, and each set includes balls arranged in a ring array on the inner wall of the sleeve. The center of each ring array is located on the center line of the sleeve, and each set of balls forms a spaced-apart ring alignment point. The ring areas of the multiple sets of ring alignment points are relatively combined to form a vertically extending hose feeding channel. Specifically, the inner diameter of the hose feeding channel gradually decreases from bottom to top, and the number of contact points between the hose and the ring alignment points at different inner diameters increases from bottom to top to correct the circumferential profile of the hose. The inner diameter of the top ring area is equal to the outer diameter of the hose. The hose feeding power unit includes a pressure feeding roller assembly. The assembly includes two opposing pressure rollers, with a pressure delivery channel between the two rollers forming a radial extrusion and shaping of the hose. There is at least one set of pressure rollers, and one or more sets of pressure rollers constitute a second shaping component with a radial alignment point. The automatic hose feeding device also includes a third shaping component located below the hose feeding power unit. The third shaping component includes a shaping tube and a rolling extruder. The rolling extruder is radially aligned along the shaping tube, and forms alignment points through radial extrusion. The extrusion amount formed by the second and third shaping components is less than or equal to 1 / 4 of the hose's outer diameter. The extrusion direction of the alignment points intersects with the extrusion direction formed by the pressure roller assembly, and a radial extrusion and shaping channel is formed between the alignment points. After the hose passes through the radial extrusion and shaping channel, the pressure delivery channel, and the hose feeding channel sequentially from bottom to top, forming multiple shaping and alignment processes, it is fed from the top of the sleeve, maintaining the hose and the pump tube of the atomizing nozzle as concentric.
[0008] Preferably, each set of ball bearings is installed via an annular mounting base and an annular cover, and each ball bearing is arranged in a universal rolling configuration, with the portion of each ball bearing protruding from the annular cover forming an annular calibration point. Using universal ball bearings not only achieves the required radial compression shaping but also provides motion guidance, further improving the uniformity of the tube length. Furthermore, it also effectively corrects minor twisting of the tubing (although the probability of twisting is small, this function does exist), further improving the product insertion quality.
[0009] According to a specific embodiment and preferred aspect of the invention, multiple sets of balls are relatively staggered along the length of the sleeve. Based on this staggered arrangement, final shaping is performed at different radial positions so that the shaped hose meets the requirements for concentric insertion.
[0010] Alternatively, multiple sets of balls can be aligned vertically along the length of the sleeve.
[0011] According to another specific embodiment and preferred aspect of the invention, the extrusion direction of the alignment point is perpendicular to the extrusion direction formed by the pressure roller assembly. This perpendicular relative extrusion shaping allows for better hose shaping.
[0012] According to another specific embodiment and preferred aspect of the invention, the extrusion amount formed by the third shaping member is greater than that formed by the second shaping member. Based on the different extrusion amounts, the resulting shaping and clamping effects are different, which is more beneficial for the shaping and recovery of the hose. Generally, the extrusion amount formed by the second shaping member is 1 / 5 of the hose's outer diameter; the extrusion amount formed by the third shaping member is 1 / 4 of the hose's outer diameter. Here, based on the limitation of the extrusion amount, it mainly avoids over-extrusion. At the same time, if the hose itself experiences over-extrusion, it can quickly achieve a near-circular cross-section shaping. That is, under two unequal extrusion amounts, it is possible to achieve a near-circular (or elliptical, with relatively similar lengths of the major and minor axes) cross-section of the hose entering the delivery channel.
[0013] In some specific embodiments, the surfaces of each pressure roller are decorated with anti-slip knurling. This anti-slip knurling prevents slippage during output and reduces the probability of relative movement of the hose.
[0014] In some specific implementations, one of the two pressure rollers is a coding roller, and the tube feeding stroke is controlled based on the number of rotations and circumference of the coding roller. The principle of a conventional coding roller is adopted to control the length of the fed or supplemented tube, thereby providing the necessary conditions for the uniformity of the hose length.
[0015] According to another specific embodiment and preferred aspect of the invention, the rolling extruder includes two extrusion rollers circumferentially offset from the pressure rollers and arranged on opposite sides of the forming tube. Using extrusion rollers not only achieves the desired extrusion shaping but also provides motion guidance.
[0016] Preferably, the extrusion roller is a follower roller, and the surface of the extrusion roller is also decorated with anti-slip knurling. The follower roller is a non-powered roller, which simplifies the structure and reduces production costs. At the same time, the anti-slip knurling prevents slippage during output and reduces the probability of relative movement of the hose.
[0017] Furthermore, a wheel seat is provided on the inner wall of the shaping tube, and the extrusion wheel is mounted on the wheel seat and rotates around a horizontal pivot.
[0018] In some specific embodiments, there are multiple sets of rolling extruders, spaced apart along the length of the forming tube. The combined extrusion and forming effect of these multiple sets results in a better overall quality improvement in the tube feeding process.
[0019] In addition, the automatic tube feeding device also includes a spring connected to the bottom of the third shaping component and fitted around the outer periphery of the tube, and a cleaning module fixed to the lower end of the spring and capable of cleaning the surface of the tube. The spring and cleaning module can swing with the traction of the tube. This elastic swinging avoids pulling on the tube and reduces the deformation rate of the tube feeding; the cleaning module cleans the surface of the tube, preventing residual objects from causing shaping failures. The cleaning module can use cleaning cotton or a cleaning cloth, etc.
[0020] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:
[0021] Existing spray hoses (rubber hoses) are inevitably subjected to compression during production or transportation, resulting in a significant probability of deformation. During actual assembly, due to the need for concentric insertion, any deformation at the hose opening will lead to insertion failure. In such cases, manual intervention is required to remove the deformed portion of the hose and reinsert it into the corresponding channel before continuous processing can continue. The probability of compression deformation directly correlates to the frequency of manual intervention, necessitating not only frequent manual work by operators but also the possibility of nozzles with missing hoses entering the market, causing considerable confusion or bottlenecks for manufacturers. Furthermore, due to the characteristics of the hose, conventional hose feeding methods are generally not adopted... Clamping methods, which increase hose deformation, rely primarily on friction for hose replacement. This leads to inconsistencies when the actual hose delivery stroke doesn't match the hose's replacement length (or when relative movement occurs between the hose and the delivery device), resulting in uneven hose lengths and reduced product yield. This invention, however, cleverly addresses these shortcomings with its integrated design of a multi-point, all-around automatic hose delivery device based on an atomizing nozzle. Using this automatic delivery device, the hose enters the radial extrusion and shaping channel, the pressure delivery channel, and the delivery channel sequentially from bottom to top, with the first and second channels forming radial directions in different directions. The extrusion and shaping process, combined with a third, progressively increasing ring-shaped and aligned stage, ensures that the hose and the pump tube of the atomizing nozzle remain concentric from the top of the sleeve during delivery. Therefore, this invention breaks with traditional delivery methods by fully utilizing alignment and extrusion in different directions to form a near-circular cross-section for shaping and clamping. Furthermore, the progressively increasing number of ring-shaped alignment points maintains the same circular cross-section output, meeting the basic requirements of concentric insertion. Therefore, the following combinations can be chosen: radial extrusion and shaping channel and delivery channel working together; or pressure delivery channel and delivery channel working together; or extrusion and shaping channel, pressure delivery channel, and delivery channel working together, to meet different requirements. The co-core output of deformed or non-deformed hoses not only eliminates the defects of poor assembly or high assembly failure rate caused by deformed hoses, but also enables continuous, efficient and high-quality production, while significantly reducing the frequency of operator intervention. On the other hand, based on the formed synchronous clamping, the defect of relative hose movement is eliminated, so that the hose length is kept equal, improving the consistency of hose assembly length. In addition, based on the extrusion amount limit, over-extrusion is avoided, and the hose cross-section entering the hose channel is shaped to be close to a circle (or the cross-section is elliptical, and the lengths of the major and minor axes are relatively close), which greatly reduces the correction pressure of the hose channel, thereby cooperating to complete the co-core output.

[0040] like Figures 1 to 5 As shown, the atomizing nozzle of this embodiment has an all-round and multi-point positioning automatic tube feeding device, which includes a sleeve 1 with a tube feeding channel inside and a tube feeding power unit 2 located below the sleeve 1 to feed the tube upward into the tube feeding channel.
[0041] In some specific embodiments, the sleeve 1 is a straight tube and is arranged in the vertical direction. At the same time, multiple sets of first shaping elements 3 are formed on the inner wall of the sleeve 1.
[0042] In this example, there are three sets of first shaping components 3 (of course, there could be two, four, or more sets), spaced apart along the length of the sleeve 1. Specifically, each set of first shaping components 3 includes a ball bearing 30 arranged in a ring array on the inner wall of the sleeve, a ring mounting base 31, and a ring cap 32. The ball bearing 30 is a universal ball bearing, and the ball bearing 30 protrudes from the ring cap 32 to form rolling contact points. At the same time, the center of the ring array of the three sets of first shaping components 3 is located on the center line of the sleeve 1, and the ball bearing 30 is aligned vertically (or staggered vertically) along the length of the sleeve 1. Based on the vertical arrangement, the final shaping is performed based on different radial positions so that the shaped hose meets the requirements for concentric insertion. Therefore, the portion of each first shaping component 3 protruding from the ring cap 32 forms a ring alignment point, and multiple ring alignment points form a vertically extending tube delivery channel. The hose G is transmitted upward from the circumferential contour at each ring alignment point.
[0043] Furthermore, the inner diameter of the tube feeding channel gradually decreases from bottom to top, and the number of contact points at different inner diameters of the tubing increases from bottom to top to correct the circumferential profile of the tubing. The inner diameter of the annular area at the top is equal to the outer diameter of the tubing. That is, in the gradually decreasing annular correction points, the number of contacts between the ascending tubing and the corresponding correction points increases (note that this does not refer to an increase in the number of correction points in each annular area, but rather an increase in the number of actual contacts between the tubing and the corresponding annular area), thereby gradually correcting the alignment and achieving concentric output. However, these three sets of first shaping components can only be used for tubing with small deformation. For tubing with large deformation, it is obviously impossible to achieve the required concentric output. In addition, the reason why the increase in the number of correction point contacts is related to the inner diameter of the tube feeding channel is mainly to gradually correct the cross-sectional shape of the tubing and to achieve optimal concentric output of the tubing as the number of contact points increases.
[0044] In some specific embodiments, the tube feeding power unit 2 includes a pressure roller assembly 20 and a power motor. The pressure roller assembly 20 includes two pressure rollers 200 that move in opposite directions, wherein the pressure channel between the two pressure rollers 200 forms a radial extrusion and shaping of the tube G.
[0045] In this example, there is one set of pressure rollers 20 (of course, two or more sets are also possible), and the pressure roller set 20 constitutes the second shaping element of the radial calibration point; at the same time, the wheel surface of each pressure roller 200 is decorated with anti-slip knurling s. This anti-slip knurling prevents output slippage and reduces the probability of relative movement of the hose. In addition, one of the two pressure rollers 200 is a coding roller, and the hose feeding stroke is controlled based on the number of turns and circumference of the coding roller. The principle of a conventional coding machine is adopted to control the length of the hose feeding or replenishment, thereby providing the necessary conditions for the uniformity of hose length.
[0046] In some specific embodiments, the automatic pipe feeding device also includes a third shaping component 4 disposed below the pipe feeding power unit 2. The third shaping component 4 includes a shaping tube 40 and a rolling extruder 41. The rolling extruder 41 is arranged radially along the shaping tube, and the rolling extruder 41 forms alignment points by radial extrusion. The extrusion direction of the alignment points intersects with the extrusion direction formed by the pressure feeding wheel group 20, and a radial extrusion shaping channel is formed between the alignment points.
[0047] In this example, the extrusion direction formed by the alignment point is perpendicular to the extrusion direction formed by the pressure roller assembly 20. This perpendicular relative extrusion shaping achieves better hose shaping. The extrusion amount formed by the third shaping component 4 (i.e., the extrusion amount formed by the rolling extruder 41) is greater than the extrusion amount formed by the second shaping component (i.e., the extrusion amount formed by the pressure roller assembly 20). Based on the different extrusion amounts, the resulting shaping and clamping effects are different, which is more beneficial for the hose's plastic recovery. In this example, the extrusion amount formed by the second shaping component is 1 / 5 of the outer diameter of the hose G; the extrusion amount formed by the third shaping component 4 is 1 / 4 of the outer diameter of the hose G. Due to the limitation on the extrusion amount, it mainly avoids over-extrusion. At the same time, if the hose itself experiences over-extrusion, it can quickly achieve a near-circular cross-section shaping. That is, under two unequal extrusion amounts, the cross-section of the hose entering the delivery channel can be nearly circular (or the cross-section is elliptical, and the lengths of the major and minor axes are relatively close) to achieve shaping.
[0048] In some embodiments, a wheel seat 42 is provided on the inner wall of the shaping tube 40, and the extrusion roller 410 is mounted on the wheel seat 42 rotating around a horizontal pivot. There is one set (or multiple sets, spaced apart along the length of the shaping tube) of rolling extruder 41. Multiple sets create a superimposed extrusion and shaping effect, thereby improving the quality of the tube feeding. The rolling extruder 41 includes two extrusion rollers 410 that are circumferentially offset from the pressure roller 200 and aligned on opposite sides of the shaping tube 40. Using extrusion rollers 410 not only achieves the required extrusion and shaping but also provides motion guidance. The extrusion rollers 410 are follower rollers, and anti-slip knurling is also arranged on their surfaces. Follower rollers are unpowered rollers, simplifying the structure and reducing production costs. The anti-slip knurling prevents slippage during output and reduces the probability of relative movement of the hose. In addition, the automatic tube feeding device also includes a spring 5 connected to the bottom of the third shaping component 4 and fitted around the outer periphery of the tube G, and a cleaning module 6 fixed to the lower end of the spring 5 and capable of cleaning the surface of the tube G. The spring 5 and the cleaning module 6 can swing with the traction of the tube G. Based on the elastic swing, the traction of the tube is avoided to prevent pulling and reduce the deformation rate of the tube feeding; based on the cleaning module to clean the surface of the tube, the residual objects on the surface of the tube are avoided to prevent the shaping failure rate. At the same time, the cleaning module can use cleaning cotton or cleaning cloth, etc.
[0049] Furthermore, it needs to be further explained that: ① This application completely overturns the traditional hose feeding method. Regardless of whether the hose is deformed, it undergoes at least three shaping processes. Based on the movement of the hose during deformation and overall operation, this maintains the concentricity of the hose output, significantly reducing assembly failures and manual intervention rates, thus providing conditions for high-efficiency and high-quality assembly. In other words, it fundamentally solves the pain points in actual production. ② For hoses with large deformation, under two different directions of alignment and extrusion, it is possible that both extrusions will occur, or only one of them will. For hoses with small or no deformation, there are generally two extrusions. However, in this application, whether it is one or two extrusions, the principle of alignment and shaping ensures that the hose cross-section is close to a circle when it enters the hose feeding channel. Then, in cooperation with the hose feeding channel, based on the gradual increase of actual contact calibration points, the output hose is kept concentric.
[0050] In summary, with this automatic tubing feeding device, the tubing enters the radial extrusion and shaping channel, the pressure feeding channel, and the tubing feeding channel sequentially from bottom to top. The first and second channels form radial extrusion and shaping in different directions, which, combined with the progressively increasing shaping and alignment at the third annular point, ensures that the tubing is fed from the top of the sleeve, maintaining concentricity between the tubing and the pump tube of the atomizing nozzle. Therefore, this invention breaks with traditional tubing feeding methods by fully utilizing the alignment extrusion in different directions to form a near-circular cross-section shape and clamping. Furthermore, the progressively increasing alignment at the annular alignment points maintains the same circular cross-section output, meeting the basic requirements for concentric insertion. Therefore, the radial extrusion and shaping channel and the tubing feeding channel can be used in combination; or the pressure feeding channel and the tubing feeding channel can be used in combination. Alternatively, a combination of extrusion and shaping channels, pressure feeding channels, and tube feeding channels can be used to achieve co-core output of hoses with varying degrees of deformation or no deformation. This not only eliminates defects such as poor assembly or high assembly failure rates caused by deformed hoses but also enables continuous, efficient, and high-quality production, while significantly reducing operator intervention frequency. Furthermore, the synchronous clamping eliminates the defect of relative tube movement caused by the hose itself, ensuring equal tube lengths and improving the consistency of hose assembly lengths. Thirdly, the use of universal ball bearings not only achieves the required radial extrusion and shaping but also provides motion guidance, further improving the uniformity of tube length. Additionally, there's another layer of meaning: when a small amount of hose twisting occurs (although the probability of twisting is small, it is indeed...) With this function, it can also be reset well, further improving the product insertion quality; fourthly, multiple sets of balls are relatively staggered or vertically aligned along the length of the sleeve, that is, based on the vertical layout, different radial positions are formed for final shaping, so that the shaped hose meets the requirements of concentric insertion; fifthly, the alignment and correction point forms a compression direction perpendicular to the compression direction formed by the pressure feeding wheel group, and a vertical relative compression shaping is adopted, which can better achieve hose shaping. At the same time, based on the different compression amounts formed by the shaping components, the shaping and clamping effects are different, and it is more conducive to the plastic recovery of the hose. Generally, the compression amount formed by the second shaping component is 1 / 5 of the hose outer diameter, and the compression amount formed by the third shaping component is... The diameter is 1 / 4 of the outer diameter of the hose. That is, based on the limitation of the extrusion amount, it mainly avoids excessive extrusion. At the same time, once the hose itself is over-extruded, it can also be quickly shaped into a near-circular cross section. In other words, under two unequal extrusion amounts, the cross section of the hose entering the hose delivery channel can be shaped into a near-circular cross section (or the cross section is elliptical, and the lengths of the major and minor axes are relatively close). The sixth aspect is that the wheel surface of each pressure roller is decorated with anti-slip knurling. This anti-slip knurling avoids output slippage and reduces the probability of relative movement of the hose. At the same time, one of the two pressure rollers is a code roller, and the number of turns and circumference of the code roller are used to control the hose delivery stroke. That is, the principle of conventional code rollers is used to control the length of the hose delivery or replacement, thereby providing the necessary conditions for the uniformity of hose length.The seventh aspect utilizes an extrusion wheel, which not only forms the required extrusion shape but also provides motion guidance. The extrusion wheel is a follower wheel, and its surface is also decorated with anti-slip knurling. This means the follower wheel is a non-powered wheel, simplifying the structure and reducing production costs. The anti-slip knurling also prevents slippage during output, reducing the probability of relative movement of the hose. The eighth aspect involves a spring and cleaning module that swings with the hose's traction, preventing pulling and reducing the deformation rate of the hose. The cleaning module cleans the hose surface, preventing residual substances from causing shaping failures. The cleaning module can use cleaning cotton or cloth, etc.
[0051] The present invention has been described in detail above, with the aim of enabling those skilled in the art to understand and implement the invention. However, this description should not be construed as limiting the scope of protection of the invention. All equivalent changes or modifications made in accordance with the spirit and essence of the invention should be included within the scope of protection of the invention.
