Description

Technical Field

[0001] This invention relates to the field of spray sunscreen production, and more specifically to a filling device for spray sunscreen production. Background Technology

[0002] Filling is one of the production processes for spray sunscreens, which involves filling the concentrated sunscreen solution into cans. Specifically, one or more precision-machined pistons reciprocate within a cylinder, drawing a fixed volume of concentrate with each stroke and then pushing it into the can.

[0003] During filling, sunscreen concentrates typically contain emulsifiers and surfactants. If the liquid is dropped from a height onto the surface (or the bottom of an empty can), it easily generates a large amount of foam. The unstable volume of the foam can lead to inaccurate filling volumes. Furthermore, the impact of the liquid flow can cause splashing, with some droplets adhering to the can opening or upper wall, failing to reach the metered portion and resulting in volume loss and fluctuations in the actual weight of each can. Therefore, immersion filling is generally used. Specifically, the filling head is lowered and inserted into the can, close to the bottom, allowing the liquid to flow from the bottom, thus solving the aforementioned problems. However, this method still has some areas for improvement. For example, the technical means to address the above problems is to ensure a smooth and stable injection process with minimal surface turbulence, thereby reducing foam and splashing. However, initially, the can is empty. During the initial stage of liquid injection and surface formation, fluctuations are inevitable. Since the filling process typically takes only a few seconds, subsequent injection from the bottom further exacerbates these fluctuations. In other words, this only reduces foaming and splashing, but does not eliminate them. Therefore, this invention proposes a filling device for spray sunscreen production that, based on the aforementioned techniques, further reduces foaming and splashing, improving filling quality. Summary of the Invention

[0004] To address the problems mentioned in the background above, the present invention provides a filling device for the production of spray sunscreens.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0006] A filling device for producing spray sunscreen includes a filling component. The filling component includes a fixed bracket, a movable bracket 1 that is slidably arranged on the fixed bracket along the vertical direction, a movable bracket 2 that is slidably arranged on the movable bracket 1 along the vertical direction, two driving components that are arranged on the movable bracket 2, a three-way pipe 2 that is arranged between the output ends of the two driving components, and a filling component that is arranged at the remaining port of the three-way pipe 2.

[0007] The filling component includes a vertically arranged filling tube connected to a three-way pipe 2. A sealing ring is fitted on the outside of the filling tube. A spring 2 is installed between the sealing ring and an external step located at the upper end of the filling tube. A limiting ring located below the sealing ring is installed on the outside of the filling tube. An air hole is provided through the end face of the sealing ring, and a one-way valve 3 is installed in the air hole. The one-way valve 3 is used to make the air in the air hole flow upward in one direction.

[0008] As a further improvement and optimization of the present invention, the filling tube is provided with a support body near its lower end. A guide rod is slidably installed on the support body in the vertical direction. The upper end of the guide rod is located above the support body and is provided with a bolt. A spring three is sleeved on the outside of the guide rod between the bolt and the support body. A sealing head is provided at the lower end of the guide rod. Initially, under the elastic force of the spring three, the sealing head seals the lower end of the filling tube from below.

[0009] As a further improvement and optimization of the present invention, an ultrasonic vibrator is provided on the outer surface of the two-way pipe.

[0010] As a further improvement and optimization of the present invention, the driving component includes a cylindrical shell arranged vertically;

[0011] The bottom of the cylinder shell is provided with a three-way pipe, and the remaining two ports of the three-way pipe are respectively provided with one-way valve one and one-way valve two;

[0012] The ends of the one-way valves of the two driving components are connected by a replenishment pipe. The one-way valve is used to allow the concentrated sunscreen liquid in the replenishment pipe to flow into the three-way pipe in one direction.

[0013] The second three-way pipe is located between the ends of the two one-way valves of the two driving components. The one-way valve is used to allow the sunscreen concentrate in the first three-way pipe to flow into the second three-way pipe in one direction.

[0014] As a further improvement and optimization of the present invention, a piston is provided inside the cylindrical shell, and the piston is driven by a linear module set at the upper end of the cylindrical shell to move inside the cylindrical shell.

[0015] As a further improvement and optimization of the present invention, the filling component also includes a vertically arranged cylinder and a connecting bracket disposed between the cylinder output end and the movable bracket.

[0016] As a further improvement and optimization of the present invention, the movable support one is provided with a lifting component for driving the movable support two to move in the vertical direction.

[0017] As a further improvement and optimization of the present invention, the lifting component includes a synchronous belt group arranged on a movable bracket. The traction direction of the synchronous belt group is arranged vertically. There are two synchronous belt groups arranged along the axis of their own pulleys. A lifting shaft is arranged between the synchronous belts of the two synchronous belt groups. Two lifting shafts are arranged in an array along the extension direction of the synchronous belts. The lifting shafts are parallel to the pulleys of the synchronous belt groups.

[0018] One side of the movable support frame 2 has a protrusion extending outwards. The protrusion extends horizontally and is perpendicular to the axis of the lifting shaft.

[0019] The vertical line where the highest point of the pulley of the synchronous belt set is located is named Line 1, and the vertical line where the quadrant point of the pulley of the synchronous belt set faces the movable bracket 2 is named Line 2. The end of the boss is located between the two synchronous belt sets and simultaneously between Line 1 and Line 2.

[0020] As a further improvement and optimization of the present invention, a spring is provided between the movable support one and the movable support two, and the elastic force of the spring is used to drive the movable support two to move downward in the vertical direction.

[0021] Compared with the prior art, the beneficial effects of this invention are as follows:

[0022] In this case, while injecting sunscreen concentrate into the empty can through the lower end of the filling tube, the tube is simultaneously pulled upwards, keeping its lower end below and close to the liquid surface in the empty can. This achieves the purpose of injecting sunscreen concentrate into the empty can. During the injection process, the can opening is continuously sealed by a sealing ring, causing the air pressure inside the empty can to increase. When the air pressure exceeds the opening pressure of the one-way valve three, the air inside the empty can is discharged through the one-way valve three. It is important to note that the one-way valve three can only be discharged if it is pushed open by the air pressure inside the empty can. That is, during the injection of sunscreen concentrate, the area above the liquid surface in the empty can is under positive pressure. Its technical advantage lies in:

[0023] Technical effect 1: When the lower end of the filling tube is close to the bottom of the empty can and the sunscreen concentrate is injected, the liquid level in the empty can rises as the sunscreen concentrate is continuously injected, and the air pressure above the liquid level increases. Therefore, in the initial stage of injection, the liquid level fluctuation when the sunscreen concentrate enters the empty can can be effectively suppressed, thereby greatly reducing the foam and splashing problems caused by liquid level fluctuation.

[0024] Technical effect 2: During the subsequent injection of sunscreen concentrate, a constant positive pressure is maintained above the liquid surface, that is, there is always a downward suppressive pressure above the liquid surface, which can maintain the suppression of liquid surface fluctuations. Thus, when the sunscreen concentrate is injected from bottom to top, the foaming and splashing problems caused by liquid surface fluctuations are further reduced.

[0025] In summary, the combination of technical effect 1 and technical effect 2 can effectively suppress liquid surface fluctuations on the basis of existing immersion filling technology, and further reduce the foaming and splashing problems caused by liquid surface fluctuations.

[0026] Technical Effect 3: Throughout the injection process, the lower end of the filling tube is close to the liquid surface, meaning that the portion of the filling tube immersed in the sunscreen concentrate is relatively short. After filling, the filling tube is vibrated by an ultrasonic vibrator, causing the concentrate remaining on the filling tube to detach and fall into the empty tank. The advantages are: firstly, it can minimize the amount of concentrate remaining on the filling tube; secondly, the vibration shakes the remaining concentrate off and into the empty tank, thus significantly improving the injection accuracy.

Detailed Implementation

[0040] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0041] This plan is attached Figure 1 This is a schematic diagram of a spray sunscreen can, including an empty can (a), an aerosol valve (b), and a cap (c).

[0042] Reference Figures 1-11 A filling device for producing spray sunscreen includes a conveying component 100 and a filling component 200. The former is used to pull an empty can to the filling position of the filling component 200, and the latter is used to inject sunscreen concentrate into the empty can.

[0043] I. Filling components 200

[0044] Reference Figures 7-11 The filling component 200 includes a fixed bracket 207, on which a movable bracket 208 is slidably disposed in the vertical direction. Furthermore, the filling component 200 also includes a vertically arranged cylinder 201 and a connecting bracket 202 disposed between the output end of the cylinder 201 and the movable bracket 208, so that the movable bracket 208 can be moved in the vertical direction by the cylinder 201.

[0045] A movable support 209 is slidably mounted on the movable support 1 208 along the vertical direction. Furthermore, a lifting component is provided on the movable support 1 208 to drive the movable support 2 209 to move along the vertical direction.

[0046] Specifically, refer to Figure 8 and Figure 9 The lifting component includes a synchronous belt group 210 mounted on a movable bracket 208. The traction direction of the synchronous belt group 210 is arranged vertically. There are two synchronous belt groups 210 along the axis of their own pulleys. A lifting shaft 211 is arranged between the synchronous belts of the two synchronous belt groups 210. There are two lifting shafts 211 arranged in an array along the extension direction of the synchronous belts. The lifting shafts 211 are parallel to the pulleys of the synchronous belt group 210.

[0047] A spring 2092 is provided between movable support 1 208 and movable support 209. The elastic force of spring 2092 is used to drive movable support 209 to move downward in the vertical direction.

[0048] One side of the movable support 209 has a boss 2091 extending from it. The boss 2091 extends horizontally and is perpendicular to the axis of the lifting shaft 211.

[0049] The vertical line where the highest point of the pulley of the synchronous belt group 210 is located is named Line 1. The vertical line where the quadrant point of the pulley of the synchronous belt group 210 faces the movable bracket 209 is named Line 2. The end of the boss 2091 is located between the two synchronous belt groups 210 and simultaneously between Line 1 and Line 2. That is to say, during the process of the synchronous belt group 210 moving with the lifting shaft 211, the lifting shaft 211 can approach the boss 2091 from below and move the boss 2091 and the movable bracket 209 upward. The spring 1 2092 is compressed. When the lifting shaft 211 moves close to the pulley, in addition to moving upward, the lifting shaft 211 also moves laterally. The lateral movement will cause the lifting shaft 211 to gradually disengage from the movement of the boss 2091. When the lifting shaft 211 passes the highest point of the pulley, the lifting shaft 211 disengages from the contact with the boss 2091, the spring 1 2092 releases its elastic force, and drives the movable bracket 209 downward. This process is repeated.

[0050] The movable support 209 is equipped with a drive component 212, and the output end of the drive component 212 is equipped with a filling component 213. Furthermore, there are two drive components 212 arranged side by side to achieve the purpose of alternating use and ensure the continuity of the filling action.

[0051] Reference Figure 10The driving component 212 includes a vertically arranged cylindrical shell 2121, a piston 2122 is sleeved inside the cylindrical shell 2121, and the piston 2122 is driven by a linear module 2123 located at the upper end of the cylindrical shell 2121, and moves inside the cylindrical shell 2121. The linear module 2123 can be implemented using existing lead screw linear movement technology, which will not be described in detail.

[0052] The bottom of the shell 2121 is provided with a three-way pipe 2124. The three-way pipe is a technology that can be implemented in the prior art. It includes three ports, which will not be described in detail. The remaining two ports of the three-way pipe 2124 are respectively provided with a one-way valve 2126 and a one-way valve 2128.

[0053] The ends of the one-way valves 2126 of the two drive components 212 are connected by a replenishment pipe 2125. The one-way valves 2126 are used to allow the sunscreen concentrate in the replenishment pipe 2125 to flow into the three-way pipe 2124 in one direction.

[0054] A three-way pipe 2127 is provided between the ends of the one-way valve 2128 of the two drive components 212. The remaining port of the three-way pipe 2127 is connected to the filling component 213. The one-way valve 2128 is used to allow the sunscreen concentrate in the three-way pipe 2124 to flow into the three-way pipe 2127 in one direction.

[0055] The linear module 2123 of the drive unit 212 drives the piston 2122 to move downward, which pushes the sunscreen concentrate in the cylinder shell 2121 into the three-way pipe 2127, and finally flows into the filling part 213.

[0056] The linear module 2123 of the drive unit 212 drives the piston 2122 to move upward, so that the sunscreen concentrate in the storage tank connected to the replenishment pipe 2125 is drawn into the cylinder shell 2121 to achieve the purpose of replenishment.

[0057] Reference Figure 10 and Figure 11 The filling component 213 includes a filling tube 2132 that is arranged vertically and connected to the tee tube 2127.

[0058] A sealing ring 2133 is fitted on the outside of the filling tube 2132. A spring 2131 is provided between the sealing ring 2133 and the external step provided at the upper end of the filling tube 2132. A limiting ring 2136 is provided on the outside of the filling tube 2132 below the sealing ring 2133 to prevent the sealing ring 2133 from dislodging from the filling tube 2132.

[0059] The end face of the sealing ring 2133 is provided with an air hole 2134 and a one-way valve 2135 is provided inside the air hole 2134. The one-way valve 2135 is used to make the air in the air hole 2134 flow upward in one direction.

[0060] The filling tube 2132 has a support body near its lower end inside. A guide rod 2137 is slidably installed on the support body in the vertical direction. The upper end of the guide rod 2137 is located above the support body and is equipped with a bolt. A spring 2138 is sleeved on the outside of the guide rod 2137 between the bolt and the support body. A sealing head 2139 is provided at the lower end of the guide rod 2137. Initially, under the elastic force of the spring 2138, the sealing head 2139 seals the lower end of the filling tube 2132 from below.

[0061] Furthermore, an ultrasonic vibrator 214 is provided on the outer surface of the three-way pipe 2127.

[0062] The process of filling component 200 injecting sunscreen concentrate into the empty can located below it is specifically manifested as follows:

[0063] First, the cylinder 201 drives the movable bracket 208 to move down, so that the lower end of the filling tube 2132 extends into the empty can and is close to the bottom of the can. During this process, the sealing ring 2133 will press against and seal the opening of the empty can.

[0064] Then, the linear module 2123 drives the piston 2122 to move down, and the sunscreen concentrate flows into the filling pipe 2132 through the three-way pipe 1 2124 and the three-way pipe 2127, and pushes the sealing head 2139 down, so that the lower end of the filling pipe 2132 opens and the sunscreen concentrate flows into the empty can.

[0065] At the same time, the synchronous belt group 210 runs, driving the lifting shaft 211 to move. The lifting shaft 211 cooperates with the boss 2091, driving the movable bracket 209 to move upward. The movable bracket 209 moves upward together with the driving component 212 and the filling component 213.

[0066] In other words, while injecting sunscreen concentrate into the empty can through the lower end of the filling tube 2132, the filling tube 2132 is simultaneously pulled upwards, keeping its lower end below and close to the liquid surface in the empty can. This achieves the purpose of injecting sunscreen concentrate into the empty can. During the injection process, the can opening is continuously sealed by the sealing ring 2133, causing the air pressure inside the empty can to increase. When the air pressure exceeds the opening pressure of the one-way valve 2135, the air inside the empty can is discharged through the one-way valve 2135. It is important to note that the one-way valve 2135 can only be discharged when it is pushed open by the air pressure inside the empty can. That is, during the injection of sunscreen concentrate, the area above the liquid surface in the empty can is under positive pressure. Its technical advantage is:

[0067] Technical effect 1: When the lower end of the filling tube 2132 is close to the bottom of the empty can and the sunscreen concentrate is injected, the liquid level in the empty can rises as the sunscreen concentrate is continuously injected, and the air pressure above the liquid level increases. Therefore, in the initial stage of injection, the liquid level fluctuation when the sunscreen concentrate enters the empty can can be effectively suppressed, thereby greatly reducing the foam and splashing problems caused by liquid level fluctuation.

[0068] Technical effect 2: During the subsequent injection of sunscreen concentrate, a constant positive pressure is maintained above the liquid surface, that is, there is always a downward suppressive pressure above the liquid surface, which can maintain the suppression of liquid surface fluctuations. Thus, when the sunscreen concentrate is injected from bottom to top, the foaming and splashing problems caused by liquid surface fluctuations are further reduced.

[0069] In summary, the combination of technical effect 1 and technical effect 2 can effectively suppress liquid surface fluctuations on the basis of existing immersion filling technology, and further reduce the foaming and splashing problems caused by liquid surface fluctuations.

[0070] Technical Effect 3: Throughout the injection process, the lower end of the filling tube 2132 is close to the liquid surface. In other words, the portion of the filling tube 2132 immersed in the sunscreen concentrate is relatively short. After filling is completed, the ultrasonic vibrator 214 drives the filling tube 2132 to vibrate, which causes the concentrate remaining on the filling tube 2132 to detach and fall into the empty can. The advantages are: on the one hand, it can minimize the amount of concentrate remaining on the filling tube 2132; on the other hand, the vibration shakes the residual concentrate off and into the empty can, thus greatly improving the injection accuracy.

[0071] After filling is completed, the drive component 212 stops filling and drives the movable bracket 208 to move upward through the cylinder 201. Then, the lifting shaft 211 disengages from the boss 2091, and the filling component 200 is reset, completing one filling cycle.

[0072] II. Conveying Components 100

[0073] Reference Figure 5 and Figure 6 The filling component 200 also includes a fixing plate 206 located below the filling component 213. A rotating disk 205 is rotatably mounted on the upper surface of the fixing plate 206, and the rotating shaft 2052 formed at the rotatable mounting location is arranged vertically. A motor 204 is powered to the end of the rotating shaft 2052, and the rotating disk 205 is coaxial with the rotating shaft 2052.

[0074] A support hole 2051 is provided through the end face of the rotating disk 205. The lower opening of the support hole 2051 is blocked by the fixing plate 206. Multiple support holes 2051 are arranged in an array along the circumference of the rotating disk 205.

[0075] Reference Figure 3 and Figure 4 The conveying assembly 100 includes a conveyor belt assembly 101, the pulleys of which are arranged vertically.

[0076] The upper surface of the conveyor belt of the conveyor belt assembly 101 is provided with placement holes 102, and multiple placement holes 102 are arranged in an array along the extension direction of the conveyor belt.

[0077] The lower surface of the conveyor belt is provided with a base plate 103, and the upper surface of the base plate 103 is provided with a discharge hole 104, a loading hole 105 and a discharge hole 106. When the conveyor belt moves, the placement hole 102 can be arranged coaxially with the three holes in sequence.

[0078] Reference Figure 6 The end face of the fixing plate 206 is provided with a top hole 2061. The top hole 2061 is coaxial with the feeding hole 105. During the rotation of the rotating disk 205, the support hole 2051 can be arranged coaxially with the discharge hole 104, the feeding hole 105, the top hole 2061, or the filling pipe 2132.

[0079] Reference Figure 5 The connecting bracket 202 is equipped with a feeding rod 203, which is coaxial with the top hole 2061.

[0080] The empty can is placed in the placement hole 102 of the conveyor belt assembly 101 by existing robotic arms or manual techniques. The empty can is moved by the conveyor belt assembly 101. When the empty can is at the discharge hole 104, it will fall into the support hole 2051 through the discharge hole 104. Then, the empty can is brought to the bottom of the filling pipe 2132 by the rotation of the rotary disk 205, and the two are coaxial.

[0081] Meanwhile, the previously filled empty can is transferred to the top hole 2061 and supported by the feeding rod 203. During the filling process, when the cylinder 201 drives the connecting bracket 202 to move upward and reset the filling component 200, the feeding rod 203 moves upward along with it, which can lift the previously filled empty can into the placement hole 102 of the conveyor belt group 101. At the same time, the conveyor belt group 101 starts and pulls the empty can away. When the can moves to the discharge hole 106, it leaves through the discharge hole 106. Of course, existing robotic arm technology can also be used to pull it away.

[0082] III. Reference Figure 5Alternatively, a first placement component 300, a screwing component 301, and a second placement component 302 can be set above the rotating disk 205, and all three are located between the filling component 200 and the feeding hole 105. The first placement component 300 is used to place the aerosol valve into the empty can after filling, and the screwing component 301 is used to screw the aerosol valve to complete the threaded connection between the aerosol valve and the empty can. The second placement component 302 is used to put the cap on the upper end of the aerosol valve. These three components can all be implemented using existing technology and are not the core of this case, so they will not be elaborated on.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
