Automatic sprayer tube insertion and cutting assembly machine

Abstract

This invention relates to an automatic sprayer tube insertion and cutting integrated assembly machine, which includes a positioning unit, a spray tube insertion unit, and a punching unit. On one hand, this invention, through the setting of a correction channel, can correct and reset deformed spray tubes. Simultaneously, after punching, the spray tube deforms and resets synchronously with automatic repositioning, eliminating the defect of misalignment during insertion due to spray tube deformation and providing the necessary conditions for high-quality spray tube insertion. On the other hand, based on the protrusion of the spray tube insertion end, the sleeve insertion end and the stepped portion are separated, allowing insertion to be performed with the reinforcement assistance of the sleeve insertion end. This ensures not only proper insertion but also prevents the spray tube from being pulled off when the sleeve insertion end falls back. Furthermore, the spray tube is further straightened during the descent of the correction channel, thereby improving the uniformity of the spray tube assembly length.

Description

Technical Field

[0001] This invention belongs to the field of sprayer processing equipment, specifically relating to an automatic sprayer tube insertion and cutting integrated assembly machine. Background Technology

[0002] A sprayer is a tool or device that disperses liquid (or partially atomizable solids) into fine droplets (or particles) using 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, pesticide application, etc.). 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 is cut according to usage needs. However, in the actual insertion process, due to the deformation and difficulty in repositioning of the spray tube itself, the following insertion defects exist:

[0003] 1) The cutting is based on the insertion of the plug, that is, the part of the insertion port is punched. The punching process will cause deformation of the injection pipe insertion port. Once the deformation cannot be restored to its natural state (or the end cannot be corrected), it will directly cause difficulty in the alignment and insertion of the next pump body. Moreover, it is easy to fail to insert properly, and there is also a probability that it cannot be inserted at all.

[0004] 2) During the insertion process of conventional plugs, the tube end expands outward due to insertion and tightens against the inner wall of the plug. When the insertion is completed, the plug will pull the spray tube as it falls, which will lead to insertion failure. At the same time, the insertion head cannot effectively straighten the spray tube, resulting in inconsistent punching lengths, which will affect the product qualification rate.

[0005] 3) The spray pipe used is generally coiled. When the spray pipe itself is squeezed or deformed, it is difficult to align and insert it. That is, the resulting disassembly and assembly strain capability is very poor. Summary of the Invention

[0006] 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 insertion and cutting assembly machine for sprayers.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] An automatic nozzle insertion and trimming assembly machine for a sprayer is disclosed. The sprayer includes a nozzle body and a spray tube. The assembly machine includes a positioning unit for the nozzle body, a spray tube insertion unit, and a cutting unit. The inlet end of the nozzle body extends downward and has a stepped portion with a gradually decreasing outer diameter and a disassembly / assembly portion extending downward from the bottom of the stepped portion. The spray tube insertion unit includes a vertically movable insertion seat, a tube insertion kit arranged vertically on the insertion seat, and a device mounted on the insertion seat that automatically pushes the spray tube out from the upper end of the tube insertion kit. The replacement assembly includes a sleeve, a set of balls formed on the inner wall of the sleeve and rolling freely, the sets of balls being spaced vertically and circumferentially around the sleeve to form an annular channel that rolls against the outer circumference of the spray tube, the centers of the multiple annular channels being aligned, and the multiple annular channels forming a straightening channel for the spray tube to pass through. The spray tube, ejected from bottom to top, is aligned based on the straightening channel and returns to its original position after contact with the outer circumference, and the length of the ejected tube is less than or equal to the length of the step portion; the punching unit includes a base mounted on the insert seat, a punching power component that reciprocates linearly along the direction perpendicular to the insert seat, and a punching head, wherein the punching head corresponds between two annular channels, and the punching head can enter and exit the insert seat and the sleeve to horizontally punch the spray tube inside the tube.

[0009] Preferably, the balls are staggered vertically between adjacent sets. This provides strong correction capability, facilitating the rapid repositioning of the deformed spray nozzle.

[0010] Furthermore, multiple sets of balls are gradually staggered from top to bottom. This creates a comprehensive correction, ensuring that the protruding parts are in the optimal state for assembly.

[0011] According to a specific embodiment and preferred aspect of the invention, in the axial projection of the cannula assembly, contacts formed by multiple sets of balls are distributed at intervals around the center of the sleeve; or, in the axial projection of the cannula assembly, multiple contacts are connected to form a ring that matches the outer diameter of the spray tube. Regardless of the contact distribution, they are always on a circular trajectory, thus more comprehensively implementing the self-circumferential compression correction of the spray tube.

[0012] According to another specific embodiment and preferred aspect of the invention, the sleeve penetrates the insert seat and protrudes from both the upper and lower ends, wherein the upper end constitutes the insert end, and during alignment insertion, the insert end wraps around the disassembly / removal portion; and / or, during alignment insertion, the insert end is aligned with or located below the variable diameter end of the stepped portion. Based on the design of the insert end, it not only cooperates with the ball bearing for shape correction, but also strengthens the protruding end of the sleeve to assist insertion, while the formed insertion position further improves the insertion quality (e.g., insertion in place), and will not pull the spray tube during descent, thus reducing the probability of detachment or loosening.

[0013] According to another specific embodiment and preferred aspect of the invention, there are at least two sets of balls located above the punching head. This is to optimize the correction effect while providing the necessary conditions for high-quality insertion.

[0014] According to another specific embodiment and preferred aspect of the present invention, the replacement assembly includes a replacement sleeve having a through channel inside, and a power unit mounted on the insert base and capable of moving the replacement sleeve up and down relative to the insert base. In short, after being connected to the power unit, the replacement sleeve can not only move synchronously with the insert base, but also move relative to the insert base to meet the needs of continuous supply and automatic replacement of the spray nozzle.

[0015] Preferably, at least one set of ball bearings is arranged in the through channel; that is, circumferential correction of the spray pipe can also be performed through the through channel.

[0016] Furthermore, a return spring is provided between the sleeve and the positioning sleeve, with the injection pipe extending upwards sequentially from the through-channel, the return spring, and the straightening channel. Based on this spring configuration, the operating mode of the power unit is further optimized, thus simplifying the positioning of the injection pipe.

[0017] According to another specific embodiment and preferred aspect of the invention, the assembly machine further includes a cleaning component located below the replacement sleeve, wherein the cleaning component includes a cleaning cotton freely sleeved around the periphery of the spray tube, wherein surface cleaning is performed based on the cleaning cotton moving against the underside of the replacement sleeve to allow relative movement between the spray tube and the cleaning cotton. The cleaning cotton removes residues or stains from the periphery of the spray tube, allowing a relatively clean spray tube to enter the calibration channel, improving calibration accuracy and insertion quality.

[0018] In addition, the positioning unit includes a positioning platform and a limiting pressure head located above the positioning platform that can move up and down. The limiting pressure head presses the nozzle body firmly onto the positioning platform to overcome the upward force caused by the insertion. A downward pressure force is used to counteract the upward force caused by the insertion. At this time, the downward pressure is greater than or equal to the upward force, thereby maintaining the nozzle body stationary while performing the alignment insertion.

[0019] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0020] In the current process of assembling the spray tube of a sprayer, due to the inherent deformation and difficulty in repositioning of the spray tube, the cutting is based on the insertion point, which involves punching the insertion port. This punching process causes deformation of the spray tube insertion port. Once the deformation cannot be restored to its natural state (or the end cannot be corrected), it directly leads to difficulty in aligning and inserting the next pump body, and easily results in incomplete insertion or even failure to insert at all. Furthermore, in conventional insertion methods, the tube end expands outwards during insertion, tightening against the inner wall of the insertion point. After insertion is complete... During the insertion process, the nozzle may be pulled, leading to insertion failure. Simultaneously, the insertion head cannot effectively straighten the nozzle, resulting in inconsistent cutting lengths and affecting product yield. Furthermore, the nozzles used are typically coiled, making alignment difficult when the nozzle itself is compressed or deformed, resulting in very poor assembly and disassembly strain resistance. This invention cleverly solves these shortcomings by comprehensively designing an automatic nozzle insertion and cutting assembly machine for sprayers. Using this assembly machine, firstly, based on the positioning unit, the nozzle... The main body is positioned, and the spray pipe extends upward from the calibration channel. The upward movement of the insert seat moves the spray pipe upward to insert the protruding end and the liquid inlet end of the nozzle body. Next, as the insert seat falls back, the calibration channel falls and straightens the spray pipe. At the cutting position, the cutting head enters the insert seat and sleeve to horizontally cut the spray pipe inside. Finally, the relative movement between the replacement component and the insert seat allows the cut end to protrude again after passing through the calibration channel, preparing for the next nozzle body insertion, thus completing the entire insertion process. Therefore, this invention, on the one hand, utilizes the calibration channel... The design can correct the deformation of the spray pipe and reset it. At the same time, after punching, the spray pipe deforms and resets synchronously with the automatic replacement. This not only eliminates the defect of not being able to be aligned and inserted due to the deformation of the spray pipe, but also provides the necessary conditions for high-quality insertion of the spray pipe. On the other hand, based on the protrusion of the spray pipe insertion end, the sleeve insertion end and the stepped part are separated. Thus, the insertion is carried out with the reinforcement assistance of the sleeve insertion end. Not only is the insertion in place, but the spray pipe will not be pulled off when the sleeve insertion end falls back. At the same time, the spray pipe is further straightened during the fall of the correction channel, thereby improving the uniformity of the spray pipe assembly length. Attached Figure Description

[0032] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Therefore, they should not be construed as limitations on this invention.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0038] like Figures 1 to 6 As shown in this embodiment, the automatic tube insertion and cutting assembly machine for the sprayer includes a nozzle body W1 and a spray tube W2. The nozzle body W1 is a commonly used push-pump assembly, and the spray tube W2 is a commonly used plastic tubing. Because plastic tubing is flexible, it is difficult to recover its shape after deformation during punching or production. The assembly machine includes a positioning unit 1 for the nozzle body W1, a spray tube insertion unit 2, and a punching unit 3. The assembly machine aligns and inserts the spray tube W2 into the nozzle body W1, and then punches the spray tube to the required length to complete the assembly process.

[0039] Specifically, the positioning unit 1 includes a positioning platform 10 and a limiting pressure head 11 located above the positioning platform 10 and capable of vertical movement. The limiting pressure head 11 presses and positions the nozzle body W1 onto the positioning platform 10 to overcome the upward force caused by the insertion. A downward pressure force is used to counteract the upward force caused by the insertion; this downward pressure is greater than or equal to the upward force, thus maintaining the nozzle body W1 stationary during alignment and insertion. In this example, the liquid inlet end of the nozzle body W1 extends downwards and has a stepped portion t with a gradually decreasing outer diameter and a disassembly / removal portion c extending downwards from the bottom of the stepped portion t.

[0040] The spray tube insertion unit 2 includes an insertion seat 20 that moves up and down, a tube insertion kit 21 arranged in the up and down direction on the insertion seat 20, a replacement component 22 installed on the insertion seat 20 and capable of automatically filling and ejecting the spray tube W2 from the upper end of the tube insertion kit 21, and a power component 23.

[0041] In some specific embodiments, the cannula assembly 21 includes a sleeve 210 and multiple sets of freely rolling balls 211 formed on the inner wall of the sleeve 210. The multiple sets of balls 211 are spaced vertically, and each set of balls 211 is spaced around the circumference of the sleeve to form an annular channel that rolls against the outer circumference of the spray tube W2. The centers of the multiple annular channels are aligned, and the multiple annular channels form a straightening channel for the spray tube to pass through. The spray tube W2, which is pushed out from bottom to top, is aligned based on the straightening channel and then emerges from the top of the sleeve after restoring its deformation. The length of the emerging part is equal to the length of the stepped portion t. The sleeve 210 passes through the insertion seat 20 and emerges from both the upper and lower ends, wherein the upper end forms the insertion end m, and the insertion end m is wrapped around the disassembly part during alignment insertion; and / or, during alignment insertion, the insertion end m is located below the variable diameter end of the stepped portion. Based on the design of the insert end, it not only works with the ball bearings for shape correction but also strengthens the protruding end of the sleeve to assist in insertion. Simultaneously, the resulting insertion position further improves the quality of insertion (e.g., proper insertion), and reduces the probability of detachment or loosening by not pulling on the spray tube during retraction. Each pair of adjacent sets of ball bearings 211 are staggered vertically. This results in strong correction capability, facilitating rapid repositioning of the deformed spray tube. Multiple sets of ball bearings 211 are progressively staggered from top to bottom. This provides comprehensive correction, ensuring the protruding part is in the optimal assembly state. In the axial projection of the insert assembly 21, the contacts formed by multiple sets of ball bearings 211 are spaced apart around the center of the sleeve; or, in the axial projection of the insert assembly 21, multiple contacts are connected to form a ring matching the outer diameter of the spray tube. Regardless of the contact distribution, they are always on a circular trajectory, thus implementing more comprehensive peripheral compression correction of the spray tube.

[0042] The alignment component 22 includes an alignment sleeve 220 with an internal through-channel and a power unit 221 mounted on the insert base 20 and capable of moving the alignment sleeve 220 up and down relative to the insert base 20. In short, after being connected to the power unit, the alignment sleeve can not only move synchronously with the insert base 20 but also move relative to the insert base 20 to meet the needs of continuous supply and automatic alignment of the spray tube W2. In this example, at least one set of ball bearings 211 is arranged in the through-channel; that is, circumferential alignment of the spray tube can also be performed through the through-channel. Furthermore, a return spring 222 is provided between the sleeve 210 and the alignment sleeve 220, and the spray tube W2 passes through the through-channel, the return spring, and the alignment channel sequentially upwards. Based on the spring arrangement, the working mode of the power unit is further optimized, thereby simplifying the alignment of the spray tube.

[0043] The power component 23 is a commonly used transmission screw, and the forward and reverse rotation of the screw drives the insertion seat 20 to rise and fall, thereby performing insertion and retraction operations.

[0044] The punching unit 3 includes a base 30 mounted on the insert 20, a punching power member 31 that reciprocates linearly along the direction perpendicular to the insert 20, and a punching head 32, wherein the punching head 32 corresponds between two annular channels, and the punching head 32 can enter and exit the insert 20 and the sleeve 210 to punch the liquid spray tube W2 inside the tube horizontally.

[0045] In addition, the assembly machine also includes a cleaning component 4 located below the replacement sleeve 220. The cleaning component 4 includes a cleaning cotton 40 freely fitted around the outer periphery of the spray tube W2. The cleaning cotton 40 moves against the underside of the replacement sleeve 220, causing relative movement between the spray tube W2 and the cleaning cotton 40 to perform surface cleaning. The cleaning cotton removes residue or stains from the outer periphery of the spray tube, allowing a relatively clean spray tube to enter the calibration channel, improving calibration accuracy and insertion quality.

[0046] In summary, using this assembly machine, firstly, the nozzle body is positioned by the positioning unit, while the spray pipe extends upward from the correction channel. The upward movement of the insert seat moves the spray pipe upward to insert the protruding end and the liquid inlet end of the nozzle body. Secondly, as the insert seat falls back, the correction channel falls and straightens the spray pipe. At the cutting position, the punching head enters the insert seat and sleeve to horizontally cut the spray pipe inside. Finally, the relative movement between the positioning component and the insert seat causes the cut end to protrude again after passing through the correction channel, preparing for the next nozzle body insertion, thus completing the entire insertion process. Therefore, this invention, through the setting of the correction channel, can correct and reset the deformed spray pipe, and simultaneously, after punching, the spray pipe automatically repositions itself. The step-by-step deformation and reset mechanism not only eliminates the defect of misalignment during insertion due to nozzle deformation, but also provides the necessary conditions for high-quality nozzle insertion. Secondly, the protrusion at the nozzle insertion end separates the sleeve insertion end from the stepped section, allowing insertion with the reinforcement of the sleeve insertion end. This ensures proper insertion and prevents the nozzle from being pulled off during the sleeve insertion end's retraction. Furthermore, the retraction of the correction channel further straightens the nozzle, improving the uniformity of the nozzle assembly length. Thirdly, the staggered arrangement of adjacent sets of balls creates a strong correction capability, facilitating rapid reset of the deformed nozzle. Multiple sets of balls are gradually staggered from top to bottom, providing comprehensive correction and ensuring the protruding part presents the optimal assembly position. The fourth aspect is that regardless of the distribution of the contact points, they are always on a circular trajectory, thus enabling more comprehensive self-circumferential extrusion correction of the spray tube; the fifth aspect is that based on the design of the sleeve end, it not only works with the ball bearings for shape correction, but also strengthens the protruding end of the sleeve to assist in insertion, while the resulting insertion position further improves the quality of insertion (e.g., insertion in place), and will not pull the spray tube during descent, reducing the probability of detachment or loosening; the sixth aspect is that there are at least two sets of ball bearings above the punching head to ensure the best correction effect and provide the necessary conditions for high-quality insertion; after the auxiliary sleeve is connected to the power unit, it can not only move synchronously with the insertion seat, but also move relative to the insertion seat to meet the needs of continuous supply and automatic operation of the spray tube. In addition to the need for alignment, at least one set of ball bearings is arranged in the through channel; that is, the circumferential alignment of the spray tube can also be performed through the through channel. At the same time, a return spring is also provided between the sleeve and the alignment sleeve. The spray tube passes through the through channel, the return spring, and the alignment channel in sequence. Based on the spring setting, the working mode of the power unit is further optimized, thereby making it easier to perform the alignment of the spray tube; the seventh aspect is to use cleaning cotton to remove the residue or stains on the outer circumference of the spray tube, so that the relatively clean spray tube enters the alignment channel, improving the alignment accuracy and improving the insertion quality; the eighth aspect is to use the downward pressure to counteract the upward force caused by the insertion. At this time, the downward pressure is greater than or equal to the upward force, thereby keeping the nozzle body stationary while performing the alignment insertion.

[0047] 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.
