Description

Technical Field

[0001] This application relates to the field of filling machine technology, and in particular to a filling nozzle device. Background Technology

[0002] Existing filling machines are a type of packaging machine and play an important role in the packaging industry. With the rapid development of industries such as food, cosmetics, and pharmaceuticals, the demand for filling machines is also increasing. With the advancement of mechanical technology, filling machines have become mechanized, improving production efficiency and filling quality.

[0003] Traditional filling machines use nozzles to deliver liquid from the supply tank into the storage bottle. Some liquids are prone to foaming if sprayed directly downwards during filling. Subsequent packaging and sealing require the machine to stand and allow the foam to dissipate before further processing. To solve this problem, workers need to disassemble the nozzles and reinstall them with angled nozzles, allowing the liquid to flow down the inner wall of the storage bottle, thus reducing foaming. This frequent nozzle replacement method is time-consuming and labor-intensive and needs improvement. Utility Model Content

[0004] In order to enable the filling machine to flexibly adjust the spray direction, this application provides a filling nozzle device.

[0005] This application provides a filling nozzle device, which adopts the following technical solution:

[0006] A filling nozzle device includes a base, on which a filling unit is disposed. The filling unit includes a nozzle inner body, an outer rotating shell rotatably connected to the nozzle inner body, and a liquid inlet pipe for connecting to a liquid supply tank. The nozzle inner body is disposed at the end of the liquid inlet pipe away from the liquid supply tank. The liquid inlet pipe is disposed on the base. The nozzle inner body is provided with a first through hole and a first oblique spray hole. The outer rotating shell is provided with a second through hole for connecting to the first through hole and a second oblique spray hole for connecting to the first oblique spray hole.

[0007] By adopting the above technical solution, one end of the liquid inlet pipe is connected to the liquid supply tank, and the other end is connected to the inner body of the nozzle, so that the liquid in the liquid supply tank can smoothly enter the inner body of the nozzle through the liquid inlet pipe. The outer rotating shell is rotatably connected to the inner body of the nozzle. When the second straight through hole on the outer rotating shell is connected to the first straight through hole in the inner body of the nozzle, the side wall of the outer rotating shell will block the first oblique spray hole in the inner body of the nozzle. At this time, the liquid can only be sprayed out from the first and second straight through holes. When the second oblique spray hole on the outer rotating shell is connected to the first oblique spray hole in the inner body of the nozzle, the bottom of the outer rotating shell will block the first straight through hole in the inner body of the nozzle. At this time, the liquid can only be sprayed out from the first and second oblique spray holes. Thus, the operator only needs to rotate the outer rotating shell to flexibly adjust the spray direction, which improves the practicality and filling efficiency of the filling machine.

[0008] Preferably, the base is provided with a drive mechanism for driving the outer housing to rotate.

[0009] By adopting the above technical solution and utilizing the drive mechanism, the drive mechanism can drive the outer rotating shell to rotate, thereby realizing the automatic adjustment of the spray direction, improving filling efficiency, and reducing the complexity and labor intensity of manual operation.

[0010] Preferably, the driving mechanism includes a rack slidably disposed on the base and a limiting component for limiting the rack, and a gear for meshing with the rack is fixedly disposed on the outer rotating housing.

[0011] By adopting the above technical solution, the rack on the base and the gear on the outer rotating shell form a meshing transmission. By operating the rack to slide, the rack drives the gear and the outer rotating shell to rotate smoothly. The position of the rack is limited by the limiting component, which ensures that the outer rotating shell maintains a stable position during the filling process.

[0012] Preferably, the limiting component includes a connecting plate and a limiting bolt. The connecting plate is disposed on the rack, and the limiting bolt is threadedly connected to the connecting plate. The base is provided with threaded holes for forming a threaded engagement with the limiting bolt, and the array of threaded holes is provided with a plurality of such holes.

[0013] By adopting the above technical solution, and using the connecting plate and the limiting bolt, after the connecting plate and the rack slide to the appropriate position, they are connected to the base by the limiting bolt, thereby fixing the position of the rack, that is, locking the rotation angle of the outer rotating shell, and thus achieving precise filling control.

[0014] Preferably, the base includes a main body and a lifting plate, the lifting plate is slidably disposed on the main body, a fixing rod is disposed on the main body, the liquid inlet pipe and the rack are both disposed on the lifting plate, and a first cylinder is disposed on the lifting plate, the piston rod of the first cylinder being fixedly connected to the fixing rod.

[0015] By adopting the above technical solution, since the piston rod of the first cylinder is fixedly connected to the fixed rod, the lifting plate is driven to move up and down on the main body by the extension and retraction of the first cylinder. Thus, the lifting plate drives the liquid inlet pipe and the inner body of the nozzle to move up and down, thereby realizing the automatic lifting of the filling process.

[0016] Preferably, the main body is symmetrically provided with a clamping assembly for clamping and fixing the outer rotating shell and a second cylinder for driving the clamping assembly to slide on the main body.

[0017] By adopting the above technical solution, the clamping component can stably fix the outer rotating shell and prevent the nozzle inner body and the outer rotating shell from shaking during the filling process. The second cylinder drives the clamping component to slide on the main body, thereby realizing the automatic clamping or release of the outer rotating shell during the filling process, which facilitates the lifting plate to drive the liquid inlet pipe and the nozzle inner body to rise and fall.

[0018] Preferably, the clamping assembly includes a sliding rod and a clamping plate for clamping and fixing the outer rotating housing. The sliding rod is slidably disposed on the main body, the piston rod of the second cylinder is connected to the sliding rod, and the clamping plate is disposed on the sliding rod.

[0019] By adopting the above technical solution, and utilizing the sliding rod and clamping plate, the second cylinder drives the sliding rod to clamp the clamping plate and fix the outer rotating shell, thereby ensuring the stability of the nozzle inner body and the outer rotating shell during the filling process.

[0020] Preferably, a contour groove is provided on the side of the clamping plate near the outer rotating shell, and the outer rotating shell and the contour groove of the clamping plate form an abutting fit.

[0021] By adopting the above technical solution and utilizing the contour groove, the clamping plate can clamp the outer shell more tightly, preventing the outer shell from shaking during the filling process and affecting the filling effect, thereby improving the stability of the filling process.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. One end of the liquid inlet pipe is connected to the liquid supply tank, and the other end is connected to the inner body of the nozzle, allowing liquid in the liquid supply tank to smoothly enter the inner body of the nozzle through the liquid inlet pipe. The outer rotating housing is rotatably connected to the inner body of the nozzle. When the second straight through hole on the outer rotating housing is connected to the first straight through hole in the inner body of the nozzle, the side wall of the outer rotating housing will block the first oblique spray hole in the inner body of the nozzle. At this time, liquid can only be sprayed out from the first and second straight through holes. When the second oblique spray hole on the outer rotating housing is connected to the first oblique spray hole in the inner body of the nozzle, the bottom of the outer rotating housing will block the first straight through hole in the inner body of the nozzle. At this time, liquid can only be sprayed out from the first and second oblique spray holes. Thus, the operator only needs to rotate the outer rotating housing to flexibly adjust the spray direction, improving the practicality and filling efficiency of the filling machine.

[0024] 2. The rack on the base and the gear on the outer rotating shell form a meshing transmission. By operating the rack to slide, the rack drives the gear and the outer rotating shell to rotate smoothly. The position of the rack is limited by the limiting component, which ensures that the position of the outer rotating shell remains stable during the filling process.

[0025] 3. The clamping assembly can stably fix the outer rotating shell, preventing the nozzle inner body and the outer rotating shell from shaking during the filling process; the second cylinder drives the clamping assembly to slide on the main body, thereby realizing the automatic clamping or release of the outer rotating shell during the filling process, which facilitates the lifting plate to drive the liquid inlet pipe and the nozzle inner body to rise and fall.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0033] This application discloses a filling nozzle device.

[0034] Reference Figure 1 A filling nozzle device includes a base 1, which includes a main body 11 and a lifting plate 12. Both ends of the lifting plate 12 in the length direction are in sliding engagement with the main body 11. A filling unit 13 is provided on the lifting plate 12. Multiple filling units 13 are provided. In this embodiment, three filling units 13 are provided. Since the structure and connection method of the three filling units 13 are the same, one of the filling units 13 will be used as an example for explanation.

[0035] Reference Figure 2 and Figure 3 The filling unit 13 includes a nozzle inner body 131, an outer rotating shell 132, and a liquid inlet pipe 133 for connecting to the liquid supply tank. The nozzle inner body 131 and the outer rotating shell are rotatably connected. In this embodiment, a stepped surface 1311 is provided on the outer ring of the nozzle inner body 131. The inner ring of the outer rotating shell 132 and the stepped surface 1311 of the nozzle inner body 131 form an abutting fit, that is, the outer rotating shell 132 is sleeved on the nozzle inner body 131. By using the stepped surface 1311 on the nozzle inner body 131, the outer rotating shell 132 can be stably rotated on the nozzle inner body 131, preventing the outer rotating shell 132 from falling off during rotation.

[0036] Reference Figure 1 and Figure 2The liquid inlet pipe 133 is installed on the lifting plate 12. The nozzle inner body 131 is threadedly connected to the end of the liquid inlet pipe 133 away from the liquid supply tank, so that the liquid in the liquid supply tank can smoothly enter the nozzle inner body 131 through the liquid inlet pipe 133. The nozzle inner body 131 is provided with a first through hole 1312 and a first oblique spray hole 1313. Three first through holes 1312 are arranged in a circumferential array, and any one of the first through holes 1312 is located at the bottom of the nozzle inner body 131. Three first oblique spray holes 1313 are arranged in a circumferential array, and any one of the first oblique spray holes 1313 is located on the periphery of the nozzle inner body 131. The bottom of the outer rotating shell 132 is provided with a second through hole 1321 corresponding to the shape and number of the first through hole 1312. The periphery of the outer rotating shell 132 is provided with a second oblique spray hole 1322 corresponding to the shape and number of the second oblique spray hole 1322.

[0037] Reference Figure 2 and Figure 3 When filling liquids that do not easily foam, the outer rotating housing 132 is rotated so that the second through hole 1321 is connected to the first through hole 1312 of the nozzle inner body 131. At this time, the side wall of the outer rotating housing 132 will block the first oblique spray hole 1313 of the nozzle inner body 131, so the liquid can only be sprayed out from the first through hole 1312 and the second through hole 1321.

[0038] Reference Figure 2 and Figure 3 When filling liquids that are prone to foaming, rotating the outer housing 132 connects the second oblique spray hole 1322 with the first oblique spray hole 1313 of the nozzle inner body 131. At this time, the bottom of the outer housing 132 will block the first through hole 1312 of the nozzle inner body 131, so the liquid can only be sprayed from the first oblique spray hole 1313 and the second oblique spray hole 1322, and the liquid can be sprayed onto the inner wall of the storage bottle, reducing the foaming of the liquid. With the design of the nozzle inner body 131 and the outer housing 132, the operator only needs to rotate the outer housing 132 to flexibly adjust the spray direction, which improves the practicality and filling efficiency of the filling machine.

[0039] Reference Figure 1 and Figure 4 The lifting plate 12 is provided with a drive mechanism 124, a sliding groove 125 and a threaded hole 126 for driving the outer rotating housing 132 to rotate.

[0040] Reference Figure 4 and Figure 5The drive mechanism 124 includes a rack 1241 that is slidably disposed in a sliding groove 125 and a limiting component 1242 for limiting the rack 1241. A gear 1323 is fixedly disposed on the outer rotating housing 132. In this embodiment, the gear 1323 is welded to the outer rotating housing 132, and the rack 1241 and the gear 1323 form a meshing transmission.

[0041] Reference Figure 4 and Figure 5 A lever 12411 is welded to one end of the rack 1241 away from the gear 1323 to facilitate the sliding of the rack 1241 by the operator. The limiting component 1242 includes a connecting plate 12421 and a limiting bolt 12422. The connecting plate 12421 is welded to the lever 12411, and the limiting bolt 12422 is threadedly connected to the connecting plate 12421. Multiple threaded holes 126 are arranged in a linear array. In this embodiment, four threaded holes 126 are provided, and any threaded hole 126 can form a threaded engagement with the limiting bolt 12422.

[0042] Reference Figure 4 and Figure 5 When in use, the operator pushes the lever 12411 to drive the rack 1241 to slide in the sliding groove 125, so that the rack 1241 drives the gear 1323 and the outer rotating housing 132 to rotate smoothly. When the outer rotating housing 132 rotates to the appropriate position, the position of the rack 1241 is limited by the limiting bolt 12422, thereby fixing the position of the rack 1241.

[0043] Reference Figure 1 and Figure 5 When the position of the rack 1241 is limited, the rotation angle of the outer rotating housing 132 is also locked, thereby achieving precise filling control. The lifting plate 12 is provided with a guide rail 121, a sliding block 122 that slides on the guide rail 121, and a clamping ring 123 for clamping and fixing the liquid inlet pipe 133. The guide rail 121 is integrally formed on the lifting plate 12. The clamping ring 123 clamps and fixes the liquid inlet pipe 133, and the clamping ring 123 is connected to the sliding block 122 by bolt threads, so that the operator can set the liquid inlet pipe 133 in a suitable position on the lifting plate 12 by sliding the sliding block 122.

[0044] Reference Figure 1A fixing rod 111 is provided on the main body 11. Both ends of the fixing rod 111 are integrally formed on the main body 11, and the fixing rod 111 is located above the lifting plate 12. A first cylinder 127 is installed on the side of the lifting plate 12 away from the liquid inlet pipe 133. The first cylinder 127 is fixed to the lifting plate 12 by bolts. The piston rod of the first cylinder 127 is fixedly connected to the fixing rod 111. In this embodiment, a clamping block 1111 is threadedly connected to the fixing rod 111 by bolts. The clamping block 1111 clamps and fixes the piston rod of the first cylinder 127.

[0045] Reference Figure 1 and Figure 3 Since the piston rod of the first cylinder 127 is fixedly connected to the fixed rod 111, the lifting plate 12 is driven to move up and down on the main seat 11 by the extension and retraction of the first cylinder 127. Thus, the lifting plate 12 drives the liquid inlet pipe 133 and the nozzle inner body 131 to move up and down, thereby realizing the automatic lifting and lowering of the filling process.

[0046] Reference Figure 1 The main body 11 is provided with a clamping assembly 112 and a second cylinder 113 for driving the clamping assembly 112 to slide on the main body 11. There are two clamping assemblies 112 symmetrically arranged, and the second cylinders 113 are symmetrically arranged at both ends of any clamping assembly 112, that is, there are four second cylinders 113. Any second cylinder 113 is fixedly installed on the main body 11 by bolts.

[0047] Reference Figure 1 Since the two clamping components 112 have the same structure and connection method, we will now describe one of the clamping components 112 as an example. The clamping component 112 includes a sliding rod 1121 and a clamping plate 1122 for clamping and fixing the outer rotating housing 132. Both ends of the sliding rod 1121 are slidably mounted on the main seat 11. The piston rod of any second cylinder 113 is connected to the corresponding sliding rod 1121. The clamping plates 1122 are set in three positions and quantities corresponding to the filling unit 13. Any clamping plate 1122 is connected to the sliding rod 1121 by bolt thread.

[0048] Reference Figure 1 By utilizing the sliding rod 1121 and the clamping plate 1122, the second cylinder 113 is operated to drive the sliding rod 1121 to move the clamping plate 1122 to clamp and fix the outer rotating shell 132, preventing the nozzle inner body 131 and the outer rotating shell 132 from shaking during the filling process, thereby ensuring the stability of the nozzle inner body 131 and the outer rotating shell 132 during the filling process.

[0049] Reference Figure 1A contour groove 11221 is provided on the side of any clamping plate 1122 near the outer rotating shell 132. The contour groove 11221 of any clamping plate 1122 forms an abutment fit with the outer ring of the outer rotating shell 132. The contour groove 11221 enables the clamping plate 1122 to clamp the outer rotating shell 132 more tightly, preventing the outer rotating shell 132 from shaking during the filling process and affecting the filling effect, thereby improving the stability during the filling process.

[0050] The implementation principle of this application embodiment is as follows: When filling a liquid that does not easily foam, the operator first pushes the lever 12411 to drive the rack 1241 to slide in the sliding groove 125, so that the rack 1241 drives the gear 1323 and the outer rotating housing 132 to rotate smoothly, so that the second through hole 1321 is connected to the first through hole 1312 of the nozzle inner body 131, and the limit bolt 12422 is connected and fixed to the appropriate threaded hole 126 on the lifting plate 12. At this time, the side wall of the outer rotating housing 132 will block the first oblique spray hole 1313 of the nozzle inner body 131, so that the liquid can only be sprayed out from the first through hole 1312 and the second through hole 1321.

[0051] When filling liquids that are prone to foaming, the outer rotating housing 132 is rotated so that the second oblique spray hole 1322 is connected to the first oblique spray hole 1313 of the nozzle inner body 131, and the limiting bolt 12422 is connected and fixed to the appropriate threaded hole 126 on the lifting plate 12. At this time, the bottom of the outer rotating housing 132 will block the first through hole 1312 of the nozzle inner body 131, so the liquid can only be sprayed out from the first oblique spray hole 1313 and the second oblique spray hole 1322, and the liquid can be sprayed onto the inner wall of the storage bottle, reducing the foaming of the liquid. Thus, the operator only needs to rotate the outer rotating housing 132 to flexibly adjust the spray direction, which improves the practicality and filling efficiency of the filling machine.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
