Description

Technical Field

[0001] The invention relates to the technical field of tobacco machinery, and in particular to a multifunctional disassembly and assembly tool for a nozzle assembly. Background Art

[0002] The cigarette production process requires strict control of the temperature and humidity of the surrounding environment, so the high-pressure micro-mist system is widely used in conjunction with the building automatic control system to achieve temperature and humidity control. The high-pressure micro-mist nozzle is a key component of the high-pressure micro-mist system. After the water vapor is atomized through the nozzle, it sprays out mist particles, which can quickly absorb heat from the air to complete vaporization and diffusion, thereby achieving the purpose of air humidification and cooling. The nozzle is a vulnerable part. When the nozzle is severely worn, problems such as poor atomization effect, large pressure loss, easy clogging, and even seepage and leakage will occur, which will not achieve the purpose of humidification and cooling; therefore, the worn nozzle ring needs to be replaced in time.

[0003] The nozzle assembly is composed of a base and a nozzle. Due to the tight fit and high precision requirements, the nozzle assembly is easily damaged during disassembly. At present, when the nozzle assembly fails, tools such as screwdrivers and needle-nosed pliers are required to disassemble the deflector and nozzle assembly. The disassembly process is complicated and time-consuming, and the nozzle connection wire is easily broken and scrapped due to central stress overload during the disassembly process, resulting in a waste of resources.

[0004] In some special cases, when the nozzle is damaged, the nozzle base is not damaged.

[0062] like Figures 1 to 12 As shown, an embodiment of the present invention provides a multifunctional disassembly and assembly tool for a nozzle assembly, which includes a barrel 100, a clamping mechanism 200, a locking pin 900, a shell 400 and a force unloading ring 300; wherein, an accommodating hole 110 is provided in the axial direction of the barrel 100, a first locking hole 150 is provided in the radial direction of the barrel 100, and a first elastic positioning mechanism 700 is provided on the side wall of the barrel 100; the clamping mechanism 200 is rotatably arranged in the accommodating hole 110, a plurality of straight clips 210 are provided on the clamping mechanism 200, and the plurality of straight clips 210 are evenly distributed on the circumferential surface, and a second locking hole 221 is provided in the radial direction of the clamping mechanism 200; the locking pin 900 is inserted into the first locking hole 150, or The locking pin 900 is sequentially inserted into the first locking hole 150 and the second locking hole 221; the shell 400 is arranged in the accommodating hole 110, the shell 400 is connected to the clamping mechanism 200, an accommodating space is arranged in the shell 400, the straight clip 210 is arranged in the accommodating space, and the outer side surface of the straight clip 210 abuts against the inner wall of the accommodating space, and a clamping space for clamping the nozzle 1 is formed between the inner sides of multiple straight clips 210; the unloading ring 300 is arranged in the accommodating hole 110, and multiple positioning holes 320 are evenly arranged on the side wall of the unloading ring 300, the positioning holes 320 cooperate with the first elastic positioning mechanism 700, and the unloading ring 300 is also provided with a mounting hole 310 for cooperating with the nozzle base 2.

[0063] The existing high-pressure fine mist nozzle assembly generally includes a base 2 and a nozzle 1. One end of the base 2 is threadedly connected to the nozzle 1, and the other end of the base 2 has a stud 3 for connecting to the device. The installation or removal of the high-pressure fine mist nozzle assembly is achieved by applying a torque to the base 2. The base 2 is generally a hexagonal column. In this embodiment, in order to cooperate with the base 2, the mounting hole 310 on the unloading ring 300 can also be a hexagonal hole that cooperates with the hexagonal column.

[0064] When the nozzle assembly needs to be disassembled, the barrel 100 in this embodiment can be connected to the driving mechanism, and the other end of the barrel 100 can be connected to the base 2 through the mounting hole 310 on the unloading ring 300. At the same time, the nozzle 1 can pass through the mounting hole 310 and extend into the clamping space formed between the inner sides of each straight clip 210. Among them, the clamping space is a space that is approximately hole-shaped, and its diameter is slightly smaller than the outer diameter of the nozzle 1. When the nozzle 1 is inserted into the clamping space, each straight clip 210 can be squeezed, and the squeezed straight clip 210 will be twisted and tilted at a certain angle, that is, one straight clip 210 is twisted and approached to an adjacent straight clip 210 after being squeezed, and at the same time, some straight clips 210 have a tendency to expand outward in the radial direction after being squeezed, but are blocked by the shell 400. The straight clip 210 will be elastically deformed after being squeezed by the shell 400 and the nozzle 1 at the same time, so that the squeezing force of the straight clip 210 on the nozzle 1 is increased, thereby improving the clamping and fixing ability of the nozzle 1. When the base 2 is removed from the equipment, the straight clip 210 clamps the nozzle 1, so that the entire high-pressure micro-mist nozzle assembly will not fall off the disassembly tool.

[0065] During the disassembly process, the cylinder 100 can be driven to rotate by the driving mechanism, and the cylinder 100 can drive the unloading ring 300 to rotate synchronously, so that the base 2 can be driven to rotate by the unloading ring 300 to realize the disassembly of the base 2. Since the nozzle 1 is fixed on the base 2, the base 2 and the nozzle 1 can be removed as a whole at the same time when the base 2 is removed.

[0066] Conversely, when it is necessary to install the nozzle assembly on the device, the barrel 100 can be driven to rotate in the opposite direction so that the stud 3 on the base 2 is gradually tightened on the device. When the preset torque value is reached during the installation of the base 2, the base 2 cannot continue to rotate, while the barrel 100 is still rotated by the driving mechanism at this time, and the unloading ring 300 also has a tendency to rotate relative to the base 2; since the unloading ring 300 is fixedly connected to the base 2 through the mounting hole 310, the unloading ring 300 is constrained by the base 2 and cannot rotate. At this time, a torque is generated between the rotating barrel 100 and the fixed unloading ring 300, so that the part of the first elastic positioning mechanism 700 that cooperates with the positioning hole 320 is moved out of the positioning hole 320 under the action of the above-mentioned torque, so that the first elastic positioning mechanism 700 is The first elastic positioning mechanism 700 retracts slightly, and the cylinder 100 can continue to rotate relative to the unloading ring 300. When the first elastic positioning mechanism 700 reaches the next positioning hole 320, the first elastic positioning mechanism 700 can cooperate with the positioning hole 320 again. At the same time, the first elastic positioning mechanism 700 will hit the edge of the positioning hole 320, and can transmit the impact generated by the impact to the operator, and make a sound of impact. The operator can clearly judge that the base 2 has been installed through the impact and sound, and stop the operation of the driving mechanism. Of course, since the driving mechanism drives the cylinder 100 to rotate at a high speed, when the operator realizes that the preset torque has been reached, the first elastic positioning mechanism 700 may have been matched and separated with multiple positioning holes 320, and can make multiple impact sounds, so that the operator can accurately determine that the base 2 has reached the preset torque. In addition, through the cooperation between the first elastic positioning mechanism 700 and the unloading ring 300, the torque from the cylinder 100 is released when the preset torque is reached, which can avoid the unloading ring 300 and the cylinder 100 from getting stuck when the preset torque is reached, causing the drive mechanism to stall and burn out.

[0067] In addition, when the nozzle assembly is installed, when the nozzle assembly reaches a preset torque, the base 2 will no longer rotate, while the barrel 100 will continue to rotate. If the clamping mechanism 200 is fixedly connected to the barrel 100, the clamping mechanism 200 will rotate synchronously with the barrel 100. Since the straight clip 210 on the clamping mechanism 200 is clamped on the nozzle 1, when the clamping mechanism 200 rotates, the straight clip 210 will have continuous sliding friction with the nozzle 1, causing accelerated wear of the nozzle 1 and reducing the service life of the nozzle 1. For this reason, in this embodiment, the clamping mechanism 200 is rotatably arranged in the receiving hole 110 of the barrel 100, that is, the clamping mechanism 200 and the barrel 100 can rotate relative to each other, that is, when the barrel 100 rotates, the clamping mechanism 200 is kept motionless by the large static friction between the nozzle 1 and it, so that the wear of the nozzle 1 caused by the straight clip 210 can be completely avoided, and the service life of the nozzle 1 is extended.

[0068] It should be noted that the above descriptions are all about the disassembly or installation of the nozzle base 2, and since the nozzle 1 is fixed on the base 2, when the base 2 is disassembled and assembled, the base 2 and the nozzle 1 can be disassembled and assembled as a whole. During the disassembly and assembly of the base 2, the locking pin 900 is only inserted into the first locking hole 150, and does not extend into the second locking hole 221.

[0069] When only the nozzle 1 needs to be disassembled, the unloading ring 300 can be removed from the dual-purpose disassembly tool, that is, the connection between the unloading ring 300 and the base 2 is not needed, but the nozzle 1 is directly inserted into the clamping space formed between the inner sides of the plurality of straight clips 210 for clamping the nozzle 1, and the nozzle 1 is clamped by the cooperation of the straight clips 210 and the housing 400. Then, the locking pin 900 can be simultaneously inserted into the first locking hole 150 and the second locking hole 221 to achieve relative fixation between the barrel 100 and the clamping mechanism 200, so that in the process of driving the barrel 100 to rotate, the clamping mechanism 200 can be driven to rotate synchronously through the locking pin 900, thereby driving the nozzle 1 to rotate synchronously, thereby achieving the disassembly and assembly of the nozzle 1 on the base 2.

[0070] That is to say, when the base 2 is not damaged but the nozzle 1 is damaged, the nozzle 1 can be disassembled by synchronously rotating the clamping mechanism 200, the locking pin 900 and the barrel 100 without disassembling the base 2; and when the base 2 is damaged, the base 2 can be disassembled by cooperating with the unloading ring 300, the clamping mechanism 200 and the barrel 100. Thus, the dual-purpose disassembly tool realizes the selective disassembly of the nozzle base 2 or the nozzle 1, improves the disassembly efficiency, and reduces the damage caused during the disassembly process.

[0071] Specifically, the first locking hole 150 includes a transverse groove portion 152 and a straight hole portion 151, the straight hole portion 151 passes through the side wall of the cylinder 100, the transverse groove portion 152 is recessed inward from the side wall surface of the cylinder 100, and one end of the transverse groove portion 152 is vertically connected to one end of the straight hole portion 151; the locking pin 900 includes a locking section 910 and a bending section 920, the locking section 910 and the bending section 920 are rotatably connected, when the bending section 920 is rotated to a colinear position with the locking section 910, the locking section 910 is penetrated into the second locking hole 221, and the bending section 920 is penetrated into the straight hole portion 151, so that the cylinder 100 and the clamping mechanism 200 can be relatively fixed to realize the disassembly and assembly of the nozzle 1. The locking section 910 may be fully or partially inserted into the second locking hole 221 , and after the bending section 920 is inserted into the straight hole portion 151 , the end of the bending section 920 will not protrude from the surface of the side wall of the cylinder 100 .

[0072] When the bending section 920 rotates to a position perpendicular to the locking section 910, the locking section 910 is inserted into the straight hole 151, and the bending section 920 is locked in the transverse groove 152. At this time, the locking section 910 will not be inserted into the second locking hole 221, so that the barrel 100 and the clamping mechanism 200 can rotate relative to each other to realize the disassembly and assembly of the nozzle base 2. After the bending section 920 is locked in the transverse groove 152, the surface of the bending section 920 and the surface of the side wall of the barrel 100 can form a complete arc surface.

[0073] In order to ensure that the locking pin 900 can be fastened in the second locking hole 221 and prevent it from falling off during the synchronous rotation of the barrel 100 and the clamping mechanism 200, a partial internal thread can be provided in the second locking hole 221, and a partial external thread can be provided on the locking section 910 of the locking pin 900, thereby the locking pin 900 can be fastened in the second locking hole 221 through the cooperation of the internal and external threads. Of course, a partial internal thread can also be provided in the first locking hole 150, and the locking section 910 can also be threadedly connected with the first locking hole 150, thereby preventing the locking pin 900 from falling off when the barrel 100 rotates alone.

[0074] A plurality of second locking holes 221 may be evenly arranged in the circumferential direction of the clamping mechanism 200 , so that the first locking hole 150 and the second locking hole 221 can be aligned by rotating the barrel 100 at a small angle.

[0075] Among them, an inclined surface or an arc surface 211 is provided on the straight clamping piece 210 to provide a guide for the insertion of the nozzle 1, so as to facilitate the insertion of the nozzle 1 into the clamping space formed by each straight clamping piece 210, and also facilitate the nozzle 1 to gradually squeeze the straight clamping piece 210 during the insertion process, so that it undergoes elastic deformation to clamp the nozzle 1.

[0076] Furthermore, in order to enhance the clamping force of the straight clamping piece 210 on the nozzle 1 , a wear-resistant coating glue is provided on the straight clamping piece 210 .

[0077] Among them, the straight clip 210 can be a thin plate structure made of metal material, such as a copper sheet, an iron sheet, a steel sheet, etc. In this embodiment, in order to achieve a certain elasticity of the straight clip 210 so as to clamp the nozzle 1 through its own elastic deformation, while ensuring that the straight clip 210 has a certain strength and will not wear and break after long-term use, the straight clip 210 is preferably a copper sheet.

[0078] Specifically, the first elastic positioning mechanism 700 includes a limiting column 730, a first spring 720 and a first locking bolt 710; a first limiting hole 130 is provided on the side wall of the cylinder 100, and the limiting column 730 is arranged in the first limiting hole 130. After the limiting end of the limiting column 730 extends out of the first limiting hole 130, it cooperates with the positioning hole 320 on the unloading ring 300, and the two ends of the first spring 720 are respectively abutted against the limiting column 730 and the first locking bolt 710, and the first locking bolt 710 is fixedly connected to the first limiting hole 130.

[0079] After the positioning hole 320 on the unloading ring 300 is aligned with the limiting column 730, the limiting end of the limiting column 730 can be pushed into the positioning hole 320 by the elastic force of the spring, thereby positioning the unloading ring 300 in the cylinder 100 so that the unloading ring 300 can rotate with the cylinder 100.

[0080] In the process of installing the nozzle assembly to the equipment, when the tightening of the nozzle assembly has reached the preset torque, the unloading ring 300 is constrained by the nozzle base 2 and no longer rotates. At this time, as the barrel 100 continues to rotate, a torsion force is generated between the barrel 100 and the unloading ring 300, and the torsion force acts on the limit column 730, and the torsion force will generate a component force in the axial direction of the limit column 730 to push the limit column 730 out of the positioning hole 320. When the limit column 730 is completely out of the positioning hole 320, the limit column 730 is acted upon by the spring to engage with the side wall of the unloading ring 300 except the positioning hole 320. Partially maintain contact, and as the cylinder 100 rotates, the limiting end of the limiting post 730 will slide on the side wall of the unloading ring 300 until the limiting post 730 reaches the next positioning hole 320, at which time the limiting end of the limiting post 730 can be re-matched with the current positioning hole 320, and the limiting post 730 will collide with the current positioning hole 320, giving the operator a vibration touch and a collision sound, thereby reminding the operator that the nozzle assembly has been installed; at the same time, the above-mentioned matching method of the limiting post 730 and the positioning hole 320 can realize automatic unloading when the preset torque is reached, thereby avoiding the problem of sticking.

[0081] The first limiting hole 130 is a tapered hole, the limiting column 730 is a tapered column matched with the tapered hole, and the end surface of the limiting column 730 is a spherical surface.

[0082] The above-mentioned limit column 730 is a conical column, which means that the diameter of the limit column 730 gradually decreases in the direction of the limit end. When the limit column 730 is matched with the first limit hole 130, the limit column 730 can be prevented from automatically falling off from the first limit hole 130; and by setting the end face of the limit column 730 as a spherical surface, when a torque is generated between the unloading ring 300 and the cylinder 100, it is convenient to generate a component force to push the limit column 730 after the inner wall of the positioning hole 320 contacts the spherical surface, thereby avoiding jamming between the positioning hole 320 and the limit column 730.

[0083] Furthermore, the positioning hole 320 includes a conical surface 322 and a cylindrical surface 321, and the conical surface 322 and the cylindrical surface 321 are two opposite surfaces in the positioning hole 320, and the conical surface 322 and the cylindrical surface 321 are both arranged in the rotation direction of the unloading ring 300, wherein the conical surface 322 refers to the inner surface in the positioning hole 320 that forms an acute angle with the axial direction, and the cylindrical surface 321 refers to the inner surface in the positioning hole 320 that is parallel to its axial direction.

[0084] When the nozzle 1 needs to be disassembled, the cylinder 100 drives the unloading ring 300 to rotate through the limiting column 730. At this time, the limiting column 730 is always in contact with the cylindrical surface 321 in the positioning hole 320, so as to generate a tangential force on the side wall of the positioning hole 320 that can drive the unloading ring 300 to rotate, and no radial component force of the unloading ring 300 will be generated, thereby ensuring that the unloading ring 300 can rotate reliably and realizing the disassembly of the nozzle 1.

[0085] When the nozzle 1 needs to be installed, the barrel 100 drives the unloading ring 300 to rotate through the limiting column 730. At this time, the spherical surface of the limiting column 730 is always in contact with the conical surface 322 in the positioning hole 320. At this time, the spherical surface of the limiting column 730 can generate a tangential force on the conical surface 322 to drive the unloading ring 300 to rotate, and can also generate a radial force to push the limiting column 730 away from the unloading ring 300. When the base 2 of the nozzle 1 does not reach the preset torque, the tangential force can always drive the unloading ring 300 to rotate, and the limiting column 730 will not be pushed out of the positioning hole 320 by the radial force; when the base 2 of the nozzle 1 reaches the preset torque, the unloading ring 300 no longer rotates, and the radial force can push the limiting column 730 out to achieve unloading.

[0086] Further, if Figure 4 As shown, the accommodating hole 110 includes a first hole 111 and a second hole 112, the diameter of the first hole 111 is larger than the diameter of the second hole 112, the unloading ring 300 is arranged in the first hole 111, the clamping mechanism 200 and the shell 400 are arranged in the second hole 112, and the first limiting hole 130 is connected to the first hole 111.

[0087] Among them, an arc groove 330 is provided on the side wall of the unloading ring 300, and the arc groove 330 surrounds the side wall of the unloading ring 300. The limiting end of the limiting column 730 is always located in the arc groove 330, thereby preventing the unloading ring 300 from detaching from the first hole 111 after the limiting end moves out of the positioning hole 320.

[0088] Further, if Figure 5 As shown, the depth of the first hole 111 is greater than the thickness of the unloading ring 300 . After the positioning hole 320 cooperates with the limiting column 730 , a gap 113 is maintained between the step surface formed by the unloading ring 300 and the first hole 111 and the second hole 112 .

[0089] When the nozzle assembly is installed to a preset torque, the continued rotation of the barrel 100 will cause the limit post 730 to continue to engage and disengage with the multiple positioning holes 320 until the driving mechanism stops; and long-term collision, engagement or separation between the limit post 730 and the positioning hole 320 will cause accelerated wear of the positioning hole 320, thereby causing the positioning hole 320 to be unable to maintain receiving sufficient tangential force to drive the unloading ring 300 to rotate. In order to reduce the wear on the positioning hole 320, when the nozzle assembly is installed to reach a preset torque, the operator can apply a certain thrust to the barrel 100 in the direction of the nozzle assembly when hearing the first or second sound produced by the limit column 730 colliding with the positioning hole 320. When the limit column 730 rotates with the barrel 100 and contacts a portion outside the positioning hole 320, the barrel 100 is acted upon by the thrust to move axially relative to the unloading ring 300, and the moving distance is less than or equal to the above-mentioned gap 113, so that the limit column 730 can be misaligned with the positioning hole 320 in the axial direction of the unloading ring 300, so that the limit column 730 no longer engages or separates with the subsequent positioning hole 320 as the barrel 100 rotates until the driving mechanism stops; thereby reducing the number of times the limit column 730 engages with the positioning hole 320, effectively reducing the wear on the positioning hole 320 and extending the service life.

[0090] Furthermore, the disassembly and assembly tool also includes a bearing 600 . A rotating shaft 230 is also provided on the clamping mechanism 200 . The inner ring of the bearing 600 is fixedly connected to the rotating shaft 230 , and the outer ring of the bearing 600 is fixedly connected to the second hole 112 .

[0091] The inner ring of the bearing 600 and the rotating shaft 230 may be interference fit, and the outer ring of the bearing 600 and the cylinder 100 may also be interference fit. The bearing 600 can support the clamping mechanism 200 and the housing 400 to prevent the clamping mechanism 200 from shaking.

[0092] Among them, the clamping mechanism 200 is connected to the cylinder 100 through the bearing 600, which can facilitate the relative rotation of the clamping mechanism 200 relative to the cylinder 100. That is, when the cylinder 100 rotates, the clamping mechanism 200 can be kept stationary by the bearing 600. At the same time, the bearing 600 can support the clamping mechanism 200 to ensure its stability during operation.

[0093] Further, if Fig.10 and Fig.11As shown, in order to ensure the reliability of the connection between the shell 400 and the clamping mechanism 200, the clamping mechanism 200 also includes a connecting body 220, and the straight clamping piece 210 and the rotating shaft 230 are respectively arranged on both sides of the connecting body 220. The connecting body 220 is provided with an external thread, and the inner wall of the shell 400 is provided with an internal thread. After the shell 400 is sleeved on the straight clamping piece 210, it is fixedly connected to the connecting body 220 through the cooperation of the external thread and the internal thread.

[0094] Furthermore, the disassembly and assembly tool also includes a drive connector 500. A drive hole 120 is provided on the end of the barrel 100 away from the accommodating hole 110. One end of the drive connector 500 is fixedly connected to the drive hole 120, and the other end of the drive connector 500 is used to connect to the electric tool.

[0095] The driving connector 500 may be a prism with a polygonal cross section, a hexagonal prism in this embodiment, and the driving hole 120 may be a hole with a regular hexagonal cross section that matches the hexagonal prism, and the hexagonal prism may be interference-fitted with the driving hole 120. The driving connector 500 may be driven by an electric tool, which may be an electric tightening machine, an electric torque wrench, or the like.

[0096] Furthermore, the disassembly and assembly tool also includes a second spring 820, a second locking bolt 810 and a ball 830, and the second spring 820, the second locking bolt 810 and the ball 830 form a second elastic positioning mechanism 800, and a second limiting hole 140 and a third limiting hole are also provided on the side wall of the cylinder 100, and the second limiting hole 140, the third limiting hole and the driving hole 120 are connected in sequence, wherein the second limiting hole 140 and the third limiting hole are coaxial, and are both aligned with the axis of the third limiting hole. Vertically, the diameter of the second limiting hole 140 is larger than that of the third limiting hole, the ball 830 is arranged in the second limiting hole 140, and part of the ball 830 protrudes from the third limiting hole to the driving hole 120; the two ends of the second spring 820 are respectively abutted against the ball 830 and the second locking bolt 810; the second locking bolt 810 is fixedly connected to the second limiting hole 140; an annular groove 510 is provided on the driving connecting member 500, and the annular groove 510 is snap-fitted with the ball 830.

[0097] During the process of inserting the driving connector 500 into the driving hole 120, when the annular groove 510 has not reached the position aligned with the ball 830, the ball 830 is squeezed back into the second limiting hole 140 by the side wall of the driving connector 500. When the annular groove 510 reaches the position aligned with the ball 830, the ball 830 can be clamped into the annular groove 510 by the action of the second spring 820, thereby realizing the clamping limit of the driving connector 500.

[0098] In addition, since the clamping mechanism 200 is fastened in the cylinder 100 by the bearing 600, when the clamping mechanism 200 needs to be disassembled and replaced, after the annular groove 510 on the driving connector 500 cooperates with the ball 830, the driving connector 500 can continue to be pushed in the direction of the clamping mechanism 200, so that the annular groove 510 passes over the ball 830, and the driving connector 500 is abutted against the end face of the rotating shaft 230 of the clamping mechanism 200. At this time, continuing to push the driving connector 500 can realize the ejection of the clamping mechanism 200 out of the cylinder 100 and complete the disassembly.
