Description

Technical Field

[0001] This invention relates to the field of nozzle assembly technology, and more specifically, to a spray bottle nozzle assembly device. Background Technology

[0002] As a common tool for household cleaning and garden irrigation, the spray bottle's core component, the nozzle assembly, mainly consists of a shell (used to form a water flow channel) and a valve core (used to control the water flow switch and flow rate). The two need to be precisely pressed together to achieve a sealed assembly, and the assembly quality directly determines the water output stability and service life of the spray bottle.

[0003] Currently, there are two main types of assembly methods for nozzle components: manual assembly, which is suitable for small-batch production. Operators need to manually grasp the outer shell and valve core, align the valve core with the assembly hole of the outer shell, and press it into place. However, the efficiency is extremely low, the cost is high, the quality is unstable, and the uneven pressure of manual pressing can easily lead to valve core misalignment. Moreover, long-term operation can easily result in missing valve cores, requiring additional investment in quality inspection costs.

[0004] Some companies have tried using simple semi-automatic equipment to press the valve core by driving the pressure head with a cylinder, but there are still key shortcomings: on the one hand, the loading process requires manual assistance to place the outer shell and valve core in the positioning station respectively, which cannot achieve continuous flow of "loading, assembly and unloading"; on the other hand, the frictional resistance between the valve core and the inner wall of the outer shell is large during the assembly process, which can easily cause the valve core to jam or the outer shell to deform. Therefore, a spray bottle nozzle assembly device is provided. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a spray bottle nozzle assembly device, which aims to solve the problems mentioned in the background art.

[0006] The present invention provides the following technical solution: a spray bottle nozzle assembly device, including a base, on which an assembly component is disposed;

[0007] The assembly assembly includes a limiting ring mounted on a base, with an inner liner rotatably connected to the center of the limiting ring and a connecting ring on the outer side of the inner liner. The inner liner and the connecting ring rotate synchronously to simultaneously load, assemble, and unload the valve body and the outer shell.

[0008] A central column is movably connected to the middle of the inner liner, and the bottom end of the central column is fixed to the base. Several first push rods are slidably connected to the inner liner. A pressure plate is covered on the top of the inner liner. Several first material picking slots are opened on the outer side of the pressure plate, which are respectively located at one end of the corresponding first push rod. The nozzle shell is positioned by the first push rods and the first material picking slots, and is used for the inner liner, push rods and pressure plate to rotate and transport the nozzle shell.

[0009] Several second push rods are slidably connected to the connecting ring, and each second push rod has a material support rod at its top end and a pulley rod at its bottom end. A spring is sleeved on the outside of the pulley rod. An inclined groove is formed on the limiting ring, and a wave slope is formed on the inclined groove. The pulley rod is slidably connected to the inclined groove and the wave slope so that the pulley rod contacts the inclined groove, causing the second push rod and the material support rod to move upward, which is used to press the outer shell and the valve core together. The wave slope makes the second push rod and the material support rod move up and down, making the press assembly of the outer shell and the valve core more tight.

[0010] Optionally, in a possible implementation, the top end of the inner liner is provided with an installation groove, and the inner wall of the installation groove and the outer side of the central column are respectively provided with protrusions. An installation cavity is formed between the installation groove and the central column, and a plurality of connecting pins are movably connected in the installation cavity. The top ends of the plurality of connecting pins are inserted into one end of the first push rod and rotatably connected to the first push rod. The outer side of the connecting pin extends to the protrusion, so that when the inner liner drives the first push rod and the connecting pin to rotate, the connecting pin contacts the protrusion and generates an amplitude that is transmitted to the nozzle and valve core through the first push rod, thereby generating an amplitude to reduce the friction between the nozzle and the valve core.

[0011] Optionally, in a possible implementation, a bracket is slidably connected to the outer side of the pressure plate. The bracket is mounted on the base via a column, and several blocks are provided in the middle of the bracket. The cross-sectional shape of the multiple blocks is arc-shaped, and the blocks are located on the outer side of the pressure plate. A guide arc plate is embedded in the block for clamping the material between the first material feeding slot and the block for conveying and assembling.

[0012] Optionally, in a possible implementation, a first gear is provided at the bottom of the inner liner, and a second gear is provided on the outside of the first gear. The second gear meshes with the first gear, and a motor for driving the second gear to rotate is provided at the bottom of the base. A transfer disc is provided on the outside of the limiting ring, and a rotating shaft is provided at the bottom of the transfer disc. The rotating shaft is connected to the output end of the motor via a belt and pulley for synchronous driving of the second gear and the transfer disc to rotate. Several second material feeding slots are provided on the outside of the transfer disc for placing valve cores. A first vibrating feeder for feeding material is provided on one side of the transfer disc. The first vibrating feeder is located at the top of the transfer disc. A second vibrating feeder is provided on the side of the transfer disc away from the first vibrating feeder for conveying the outer shell. A hopper is provided on one side of the limiting ring, and the top of the hopper is inclined upward for conveying the assembled nozzle.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. This invention utilizes an integrated motor transmission design. The motor output drives the inner liner to rotate via the second and first gears, and also drives the transfer disc to rotate synchronously via a belt pulley. This ensures that the conveying rhythm of the outer shell driven by the inner liner is perfectly matched with the transfer rhythm of the valve core driven by the transfer disc. Simultaneously, with the addition of a first and second vibrating feeder, orderly and precise material supply is achieved without the need for manual assistance in feeding. Finally, the inclined design of the discharge hopper allows the finished product to slide out automatically, and the pressing force is stable, ensuring the assembly and sealing of the nozzle and reducing the defect rate of finished products.

[0015] 2. When the connecting pin between the inner liner and the central column rotates with the inner liner, it will intermittently contact the protrusion to generate a longitudinal amplitude. This amplitude is transmitted to the outer shell and the valve core through the second push rod, which can reduce the frictional resistance between the valve core and the inner wall of the outer shell and avoid valve core jamming or scratches on the inner wall of the outer shell; on the other hand, it can help the valve core to automatically align with the assembly hole and avoid assembly misalignment.

[0016] 3. The inclined groove of the limiting ring of the present invention is provided with a continuous wave slope. When the pulley rod slides along the inclined groove, it drives the top rod and the material support rod to move upward and downward. The upward process realizes the initial pressing of the valve core and the outer shell. The downward process eliminates the assembly gap between the valve core and the outer shell through intermittent top pressure, so that the two fit more tightly. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Example 1

[0029] The water spray bottle nozzle assembly device disclosed in this embodiment, such as Figure 1 As shown, its core includes a base 1, an assembly component set on the base 1, a transfer mechanism and a feeding and unloading mechanism. The mechanisms work together to achieve automated feeding, precise assembly and efficient unloading of the nozzle shell and valve core. No manual intervention is required throughout the process, which greatly improves assembly efficiency and reduces the risk of missing parts.

[0030] The base 1 serves as the supporting foundation for the entire device. It is made of high-strength aluminum alloy in one piece and has anti-slip pads at the bottom to ensure the stability of the device during operation. The assembly component is centrally located on the upper surface of the base 1 and is responsible for the positioning and pressing assembly of the outer shell and the valve core. The transfer mechanism is located on one side of the assembly component and is used for the precise transfer of the valve core. The feeding and unloading mechanisms correspond to the discharge ends of the transfer mechanism and the assembly component, respectively, to realize the automatic supply of materials and the output of finished products.

[0031] The assembly component is the core execution unit of this device, such as... Figure 3 , 4 As shown, it includes components such as a limiting ring 2, an inner liner 3, a connecting ring 4, a central column 5, a first push rod 6, a pressure plate 7, and a bracket 17. The specific structure is as follows:

[0032] like Figure 1 , 4 As shown, the limiting ring 2 is fixed to the upper surface of the base 1 by bolts, and has a ring structure. A groove 13 is machined around its inner wall. Figure 8 As shown, the inclined groove 13 has a continuous wave slope 14 integrally formed on the groove wall. The height difference between the crest and trough of the wave slope 14 can be set to 3-5mm, which is used to cooperate with the pulley rod 12 to realize the up-and-down movement of the second top rod 9.

[0033] like Figure 6 , 7 As shown, the inner liner 3 has a cylindrical structure, and its lower part is rotatably connected to the central through hole of the limiting ring 2 via a bearing. The connecting ring 4 is fixed to the middle of the outer wall of the inner liner 3 by screws. The two are coaxially arranged and rotate synchronously. The top of the inner liner 3 has mounting grooves evenly distributed circumferentially. The inner wall of the mounting groove and the outer wall of the central column 5 are both integrally formed with protrusions 15, such as... Figure 7 As shown, protrusion 15 is hemispherical and distributed at intervals along the circumference.

[0034] An annular mounting cavity is formed between the inner liner 3 and the central column 5, and several connecting pins 16 are movably connected within the mounting cavity, such as... Figure 6 As shown, the connecting pin 16 is cylindrical, with its top end rotatably connected to one end of the first push rod 6 via a pin shaft, and its bottom end extending above the protrusion 15. When the inner liner 3 rotates, the connecting pin 16 will intermittently contact the protrusion 15, generating longitudinal amplitude.

[0035] Several first push rods 6 are evenly slidably connected to the outer side wall of the inner liner 3 in the circumferential direction. The first push rods 6 are arranged horizontally, and the end away from the connecting pin 16 extends to the first material feeding slot 8 of the pressure plate 7, which is used to position and support the nozzle housing.

[0036] like Figure 4 , 6 As shown, the central column 5 is cylindrical, with its bottom end fixed to the center of the base 1 by a thread, and its top end extending into the interior of the inner liner 3, coaxially arranged with the inner liner 3, providing guiding support for the rotation of the inner liner 3.

[0037] like Figure 3 , 5 As shown, the pressure plate 7 has an annular disc structure and is placed on top of the inner liner 3. Several first material intake slots 8 are evenly distributed circumferentially on its outer wall. The shape of the first material intake slots 8 matches the shape of the nozzle housing and is used to accommodate the nozzle housing. The bracket 17 is fixed to the base 1 by a column and is arranged around the outside of the pressure plate 7. Several stops 18 are evenly fixed circumferentially in the middle of the bracket 17, such as... Figure 5As shown, the cross-section of the baffle 18 is arc-shaped, which is consistent with the curvature of the outer wall of the pressure plate 7. The inner wall of the baffle 18 is embedded with a guide arc plate 19. The guide arc plate 19 is made of polytetrafluoroethylene material and has a smooth surface. It is used to clamp the nozzle shell between the first material feeding slot 8 and the baffle 18 to prevent the shell from shifting during the conveying process.

[0038] like Figure 7 , 8 As shown, several second push rods 9 are slidably connected to the outer side wall of the connecting ring 4 in a circumferential direction. The second push rods 9 are arranged vertically, and a material support rod 10 is welded to their top end to support the valve core and push it into the housing. A pulley rod 12 is welded to the bottom end of the second push rod 9. A spring 11 is sleeved on the outer side of the pulley rod 12. The top end of the spring 11 abuts against the lower surface of the connecting ring 4, and the bottom end abuts against the limiting platform of the pulley rod 12 to provide a reset elastic force for the second push rod 9.

[0039] A pulley is installed at the bottom of the pulley rod 12. The pulley is rolledly connected to the inclined groove 13 and the wave slope 14 of the limiting ring 2. When the connecting ring 4 rotates with the inner liner 3, the pulley slides along the inclined groove 13 and moves up and down under the action of the wave slope 14, thereby driving the second top rod 9 and the material support rod 10 to rise and fall synchronously.

[0040] Example 2

[0041] Based on Embodiment 1, this embodiment discloses a spray bottle nozzle assembly device, including a transmission mechanism;

[0042] like Figure 1 , 7 As shown, the transmission mechanism includes a first gear 20, a second gear 21, a motor 22, and a belt drive assembly, which are used to provide power to the inner liner 3 and the transfer disc 23 and achieve synchronous rotation.

[0043] The first gear 20 is fixed to the bottom outer wall of the inner liner 3 by a key connection and is coaxially arranged with the inner liner 3;

[0044] The second gear 21 is mounted on the base 1 via a bearing seat and meshes with the first gear 20 to ensure smooth transmission;

[0045] The motor 22 is a servo motor, which is fixed to the bottom of the base 1 by bolts. Its output shaft is connected to the rotating shaft of the second gear 21 by a coupling, and is used to drive the second gear 21 to rotate.

[0046] A rotating shaft is welded to the bottom of the transfer plate 23. The rotating shaft is mounted on the base 1 through a bearing seat. The rotating shaft is connected to the output end of the motor 22 through a belt and a pulley, so that the motor 22 synchronously drives the second gear 21 and the transfer plate 23 to rotate, ensuring that the assembly rhythm is consistent.

[0047] Example 3

[0048] Based on Example 2, this example discloses a spray bottle nozzle assembly device, including a feeding and unloading mechanism;

[0049] like Figure 2 As shown, the feeding mechanism includes a first vibrating feeder 25 and a second vibrating feeder 26, and the unloading mechanism is a hopper 27.

[0050] The first vibrating feeder 25 is fixed on the base 1 and located on the top side of the transfer plate 23. Its discharge port is aligned with the second material feeding slot 24 of the transfer plate 23, and is used to orderly transport the valve core to the transfer plate 23.

[0051] The transfer plate 23 is disc-shaped, and its outer side wall is evenly provided with a number of second material picking slots 24. The shape of the second material picking slots 24 is adapted to the valve core and is used to carry and transfer the valve core.

[0052] The second vibrating feeder 26 is fixed on the base 1 and located on one side of the pressure plate 7. Its outlet is aligned with the first material receiving slot 8 of the pressure plate 7 and is used to orderly convey the nozzle housing to the first material receiving slot 8.

[0053] The feeding hopper 27 is made of stainless steel and is fixed to one side of the limiting ring 2 by a bracket. Its top is tilted upward at an angle of 30-45°. The top feed port is aligned with the discharge position of the pressure plate 7, and the bottom extends to the outside of the device to receive and transport the assembled nozzles.

[0054] The specific working principle is as follows: The water spray nozzle assembly device of this embodiment includes four stages: feeding, positioning, assembly, and unloading. The entire process is automated and synchronized. The motor 22 is started, and the motor 22 drives the second gear 21 to rotate through the coupling. The second gear 21 meshes and drives the first gear 20 and the inner liner 3 to rotate. At the same time, the motor 22 drives the transfer plate 23 to rotate synchronously through the belt and pulley. The rotational angular velocity of the inner liner 3 and the transfer plate 23 is consistent, ensuring that the assembly rhythm is matched.

[0055] When the valve core is fed, the first vibrating feeder 25 is started. Under the action of vibration, the valve core is output in an orderly manner along the discharge channel of the first vibrating feeder 25 and falls precisely into the second material picking slot 24 of the transfer plate 23. It is then transferred towards the assembly component as the transfer plate 23 rotates.

[0056] When the outer shell is loaded, the second vibrating feeder 26 is started. Under the action of vibration, the nozzle outer shell is output in an orderly manner along the discharge channel of the second vibrating feeder 26 and falls into the first material picking slot 8 of the pressure plate 7. Under the limiting action of the stop block 18 and the guide arc plate 19, the outer shell is stably clamped in the first material picking slot 8 and transferred to the assembly station with the rotation of the pressure plate 7 and the inner liner 3.

[0057] When the outer shell is transferred to the assembly station via the first material loading slot 8, the inner liner 3 drives the first push rod 6 to rotate synchronously. One end of the first push rod 6 abuts against the outer wall of the outer shell to achieve radial positioning of the outer shell. At the same time, the rotation of the inner liner 3 drives the connecting pin 16 to move around the central column 5. The bottom end of the connecting pin 16 intermittently contacts the central column 5 and the protrusion 15 on the inner liner 3, generating a longitudinal amplitude. This amplitude is transmitted to the outer shell and the valve core to be assembled later through the first push rod 6, effectively reducing the friction between the valve core and the inner wall of the outer shell, and providing convenience for subsequent pressing assembly.

[0058] When the transfer plate 23 transfers the valve core to the position directly below the assembly station, the valve core is exactly above the material support rod 10. At this time, the connecting ring 4 rotates with the inner liner 3, which drives the second push rod 9 and the pulley rod 12 to rotate synchronously. The pulley at the bottom of the pulley rod 12 slides along the inclined groove 13 of the limiting ring 2. The inclined structure of the inclined groove 13 causes the pulley rod 12 to gradually move upward, which in turn drives the second push rod 9 and the material support rod 10 to move upward. The material support rod 10 lifts the valve core upward and accurately embeds it into the nozzle housing below.

[0059] As the connecting ring 4 continues to rotate, the pulley enters the wave slope 14 area on the inclined groove 13. Under the action of the crests and troughs of the wave slope 14, the pulley rod 12 drives the second push rod 9 and the material support rod 10 to rise and fall, applying intermittent upward pressure to the valve core, making the valve core and the outer shell more tightly assembled and preventing loosening.

[0060] After assembly, the inner liner 3 continues to drive the pressure plate 7 to rotate. When the first material inlet 8 carrying the finished nozzle is transferred to the inlet of the hopper 27, under the action of the centrifugal force of the device rotation and the gravity of the finished product, the finished nozzle is separated from the first material inlet 8 and falls into the hopper 27. It slides out of the device along the inclined channel of the hopper 27, completing the entire assembly process.

[0061] In the above process, loading, positioning, assembly, and unloading are carried out synchronously and cyclically without manual intervention, which greatly improves the assembly efficiency of the spray bottle nozzle assembly. At the same time, it avoids problems such as omissions and loose assembly caused by manual assembly, making it suitable for large-scale mass production.

[0062] In this embodiment, the number of each component can be adjusted according to actual production needs. For example, the number of the first push rod 6, the first material picking slot 8, and the second material picking slot 24 can be set to 4-8, which does not affect the technical effect of the present invention.

[0063] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
