Description

Technical Field

[0001] This invention relates to the field of assembly line dispensing technology, and in particular to an assembled anti-splash device for dispensing nozzles. Background Technology

[0002] Dispensing nozzles are nozzles used for dispensing liquids or gases. They are commonly used in dispensing, filling, and spraying operations in the medical, cosmetic, food, and chemical industries. In assembly line operations, dispensing nozzles are needed to assist in the quantitative and rapid dispensing of materials. However, existing dispensing nozzles usually spray materials directly, and the existing devices lack limiting protection for the discharge port, which can easily lead to material splashing and waste. Furthermore, the simple guide sleeve is insufficient to buffer the sprayed material, resulting in excessive impact force when the material is discharged.

[0003] Therefore, in order to address the above problems, we are now developing an assembled splash-proof device for dispensing nozzles that automatically limits and prevents splashing of materials while buffering the material discharge. Summary of the Invention

[0004] To overcome the shortcomings of existing devices, such as the lack of limiting protection for the discharge port, which easily leads to material splashing and waste, and the difficulty of buffering the sprayed material with a simple guide sleeve, resulting in excessive impact force when the material is discharged, this invention provides an assembled anti-splash device for a dispensing nozzle that automatically limits and prevents splashing of the material, while also buffering the material during discharge.

[0005] The technical solution of the present invention is as follows: an assembled anti-splash device for a dispensing nozzle, comprising a dispensing nozzle, a threaded sleeve, an adapter ring, and an anti-splash mechanism. The threaded sleeve is rotatably provided on the top of the dispensing nozzle, and an adapter ring is provided on the lower part of the threaded sleeve. The dispensing nozzle is provided with an anti-splash mechanism for preventing the sprayed material from splashing. The anti-splash mechanism includes a fixing ring, a first fixing seat, an anti-splash plate, and a torsion spring. The fixing ring is provided on the lower part of the dispensing nozzle, and six first fixing seats are evenly provided on the outer edge of the fixing ring. An anti-splash plate for shielding the sprayed material is rotatably provided on each of the first fixing seats. A torsion spring is provided between each anti-splash plate and an adjacent first fixing seat, and the torsion spring is wound around the anti-splash plate.

[0006] As a preferred embodiment of the present invention, it further includes a pressure-reducing mechanism, which includes a sliding frame, a fixed frame, a guide fan blade, a bearing sleeve, a flow divider plate, and springs. The sliding frame is slidably arranged inside the dispensing nozzle, and the fixed frame is arranged inside the sliding frame for diverting and buffering the material. The bottom of the fixed frame is rotatably arranged with a guide fan blade for guiding the material. The bottom of the guide fan blade is rotatably arranged with a bearing sleeve, and the bottom of the bearing sleeve is arranged with a flow divider plate for diverting and guiding the material. Two springs are arranged symmetrically between the sliding frame and the dispensing nozzle.

[0007] As a preferred embodiment of the present invention, it further includes an expansion mechanism, which includes a sliding ring, a connecting rod, an expansion plate, and a second fixed seat. The sliding ring is slidably disposed at the lower part of the dispensing nozzle, and the connecting rod is uniformly rotatably disposed at the outer edge of the sliding ring. Six second fixed seats are uniformly rotatably disposed at the upper outer edge of the fixed ring, and an expansion plate is rotatably disposed on each of the second fixed seats for further blocking the gaps between the splash guards. The expansion plate is rotatably connected to the adjacent connecting rod.

[0008] As a preferred embodiment of the present invention, it further includes a retracting mechanism, which includes a wire frame, a pull rope, and an anti-detachment guard plate. A wire frame is provided on the inner side of each splash guard plate, and a pull rope for fixing and retracting the splash guard plate is provided between the wire frame and the diverter plate. An anti-detachment guard plate is provided on each wire frame to prevent the pull rope from loosening.

[0009] As a preferred technical solution of the present invention, it also includes a merging mechanism, which includes a merging hopper and an assisting block. The merging hopper is installed at the bottom of the diverting plate, and assisting blocks are provided on both the left and right sides of the merging hopper for easy pulling and disassembly.

[0010] As a preferred embodiment of the present invention, it further includes a scraping mechanism, which includes a rotating plate and an anti-overflow plate. The rotating plate is provided at the lower part of the guide fan blade, and the anti-overflow plate is provided on the rotating plate.

[0011] As a preferred embodiment of the present invention, the adapter rings are all multi-faceted prismatic structures.

[0012] As a preferred embodiment of the present invention, the splash guards are all of the following structure: narrow at the top and wide at the bottom.

[0013] As a preferred embodiment of the present invention, the top of the fixing frame has a sloping structure.

[0014] As a preferred embodiment of the present invention, the non-adjacent sides of the assist block are all protruding structures.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses the cooperation between the anti-splash plate and the torsion spring. When the material is sprayed out through the dispensing nozzle, the impact force of the material spraying causes the anti-splash plate to rotate and unfold, thereby automatically limiting and guiding the material, avoiding material splashing and waste, and also buffering the material and reducing the impact force of the material spraying.

[0016] 2. In this invention, the material impacts the sliding frame during the discharge process, causing the sliding frame to slide downwards, thereby compressing the springs. During this process, the material is diverted and depressurized sequentially through the fixed frame, guide fan blades, and diverter plate, thus avoiding excessive pressure when the material is sprayed out.

[0017] 3. The present invention uses the rotation and unfolding of the splash guard to drive the unfolding of the extension plate, thereby blocking and protecting the gaps between the splash guards and preventing materials from flying out through the gaps, which would result in incomplete material splash protection.

[0018] 4. The present invention uses a diverter plate to pull the pull rope, so that the pull rope can limit and lock the splash guard, preventing the splash guard from accidentally unfolding when not in use and improving the stability of the splash guard. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0029] An assembled splash guard for dispensing nozzles, such as Figure 1 and Figure 2 As shown, it includes a dispensing nozzle 1, a threaded sleeve 2, an adapter ring 3, and a splash guard 4. The top of the dispensing nozzle 1 is rotatably connected to the threaded sleeve 2, and the lower part of the threaded sleeve 2 is connected to the adapter ring 3. The adapter ring 3 has a multi-faceted prismatic structure, which is convenient for the operator to rotate and use. The dispensing nozzle 1 is equipped with a splash guard 4, which is used to prevent the sprayed material from splashing.

[0030] It should be noted that when materials need to be packaged and discharged on the production line, this device can be installed on the discharge port. By rotating the adapter ring 3, the threaded sleeve 2 is connected to the spray head of the production line. During the material spraying process, the anti-splash mechanism 4 shields and prevents the material from splashing and wasting.

[0031] like Figure 1 and Figure 3 As shown, the anti-splash mechanism 4 includes a fixing ring 41, a first fixing seat 42, an anti-splash plate 43, and a torsion spring 44. The lower part of the dispensing nozzle 1 is connected to the fixing ring 41, and six first fixing seats 42 are evenly connected to the outer edge of the fixing ring 41. An anti-splash plate 43 is rotatably connected to each of the first fixing seats 42. The anti-splash plate 43 is used to shield the sprayed material. The anti-splash plate 43 has a structure that is narrow at the top and wide at the bottom, which can effectively guide the material. A torsion spring 44 is connected between the anti-splash plate 43 and the adjacent first fixing seat 42.

[0032] It should be noted that when the material is sprayed downwards through the dispensing nozzle 1, the force of the sprayed material will impact and push the splash guards 43 to rotate and unfold to the side away from each other. The torsion springs 44 will deform under the force. At this time, the splash guards 43 unfold to guide and limit the sprayed material, avoiding material splashing and waste. It should be noted that when the dispensing nozzle 1 stops discharging material, the splash guards 43 will rotate and reset to the side closer to each other under the action of the torsion springs 44. In summary, through the cooperation between the splash guards 43 and the torsion springs 44, when the material is sprayed out through the dispensing nozzle 1, the impact force of the sprayed material causes the splash guards 43 to rotate and unfold, thereby limiting and guiding the material and avoiding material splashing and waste.

[0033] like Figure 2 and Figure 4As shown, it also includes a pressure-reducing mechanism 5, which includes a sliding frame 51, a fixed frame 52, a guide fan blade 53, a bearing sleeve 54, a flow divider plate 55, and a spring 56. The sliding frame 51 is slidably connected inside the dispensing nozzle 1, and the fixed frame 52 is connected inside the sliding frame 51. The fixed frame 52 is used to divert and buffer the material. The top of the fixed frame 52 has a sloping structure, which can reduce the impact force during the material spraying process. The guide fan blade 53 is rotatably connected to the bottom of the fixed frame 52. The guide fan blade 53 is used to guide the material. The bearing sleeve 54 is rotatably connected to the bottom of the guide fan blade 53. The flow divider plate 55 is connected to the bottom of the bearing sleeve 54. The flow divider plate 55 is used to divert and guide the material. The flow divider plate 55 can push and squeeze the upper inner side of the splash guard 43. Two symmetrical springs 56 are connected between the sliding frame 51 and the dispensing nozzle 1.

[0034] It should be noted that when the material is discharged through the dispensing nozzle 1, it will first contact the fixed frame 52 and be buffered and diverted under the guidance of the fixed frame 52. At the same time, as the fixed frame 52 is impacted by the material, the sliding frame 51 will begin to slide downward, thereby compressing the springs 56 and buffering and depressurizing the material. It should be particularly noted that when the material is discharged through the sliding frame 51, it will push the guide fan blades 53 to rotate, thereby depressurizing and diverting the material again. Finally, the material will be further depressurized and diverted through the diverting plate 55. The material is diverted and depressurized to prevent excessive pressure during spraying. At the same time, the diverter plate 55 slides downward with the sliding frame 51, which pushes the upper inner side of the splash guard 43, thereby assisting the splash guard 43 to rotate and unfold. In summary, the material impacts the sliding frame 51 during the discharge process, causing the sliding frame 51 to slide downward, which in turn compresses the spring 56. During this process, the material is diverted and depressurized in sequence through the fixed frame 52, the guide fan blade 53 and the diverter plate 55 to prevent excessive pressure during spraying.

[0035] like Figure 1 and Figure 5 As shown, it also includes an expansion mechanism 6, which includes a sliding ring 61, a connecting rod 62, an expansion plate 63, and a second fixed seat 64. The lower part of the dispensing nozzle 1 is slidably connected to the sliding ring 61, and the outer edge of the sliding ring 61 is uniformly rotatably connected to the connecting rod 62. The upper outer edge of the fixed ring 41 is uniformly rotatably connected to six second fixed seats 64, and each second fixed seat 64 is rotatably connected to an expansion plate 63. The expansion plate 63 is used to further block the gaps between the splash guards 43, and the expansion plate 63 is rotatably connected to the adjacent connecting rod 62.

[0036] It should be noted that when the splash guards 43 are impacted by materials and begin to rotate and unfold outwards, they will push the adjacent expansion plates 63 to unfold, causing the connecting rods 62 to rotate. When the connecting rods 62 begin to rotate, they will push the sliding rings 61 to slide upwards. As the expansion plates 63 rotate and unfold, they will block the gaps between the splash guards 43, thus preventing materials from flying out through the gaps between the splash guards 43. In summary, by rotating and unfolding the splash guards 43, the expansion plates 63 are pushed to rotate and unfold, thereby blocking and protecting the gaps between the splash guards 43, preventing materials from flying out through the gaps and causing incomplete material splash protection.

[0037] like Figure 1 and Figure 6 As shown, it also includes a retracting mechanism 7, which includes a wire frame 71, a pull rope 72, and an anti-detachment guard plate 73. The inner side of the splash guard 43 is connected to the wire frame 71, and the pull rope 72 is connected between the wire frame 71 and the diverter plate 55. The pull rope 72 is used to fix and retract the splash guard 43. The anti-detachment guard plate 73 is connected to the wire frame 71 to prevent the pull rope 72 from loosening.

[0038] It should be noted that when the splash guard 43 is in the retracted state, the diverter plate 55 will always maintain the traction on the pull rope 72, thereby preventing the splash guard 43 from accidentally rotating and unfolding. When the sliding frame 51 is impacted by material and begins to slide downward, it will drive the diverter plate 55 to move downward, thereby no longer pulling the pull rope 72, causing the pull rope 72 to slacken. The anti-detachment guard plate 73 will then block the pull rope 72, preventing it from detaching from the guide frame 71. At this time, the splash guard 43 can unfold under force. In summary, by pulling the pull rope 72 through the diverter plate 55, the pull rope 72 can limit and lock the splash guard 43, preventing the splash guard 43 from accidentally unfolding when not in use, thus improving the stability of the splash guard 43.

[0039] like Figure 2 and Figure 7 As shown in the figure, the merging mechanism 8 is also included. The merging mechanism 8 includes a merging hopper 81 and an assisting block 82. The merging hopper 81 is installed at the bottom of the diverting plate 55. The merging hopper 81 is connected to the left and right sides of the merging hopper 81. The assisting block 82 facilitates the pulling and disassembling of the merging hopper 81. The non-adjacent sides of the assisting block 82 are all protruding structures.

[0040] It should be noted that after the material is diverted and depressurized by the diverter plate 55, it is re-gathered by the converging hopper 81 to avoid the material being discharged in a concentrated manner and causing the material to scatter. When it is not needed, the converging hopper 81 can be pulled down by the assist block 82 to disengage the converging hopper 81 from the diverter plate 55.

[0041] like Figure 4 and Figure 8 As shown, it also includes a scraping mechanism 9, which includes a rotating plate 91 and an anti-overflow plate 92. The rotating plate 91 is connected to the lower part of the guide fan blade 53, and the anti-overflow plate 92 is connected to the rotating plate 91.

[0042] It should be noted that as the guide fan blades 53 rotate continuously, they will drive the anti-overflow plate 92 to rotate continuously, thereby scraping the upper part of the diverter plate 55 to prevent the diverter plate 55 from being blocked due to the accumulation of impurities.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
