Description

Technical Field

[0001] The utility model relates to the technical field of bottled water production, in particular to a cleaning device for a water outlet valve of a drinking water barrel. Background Art

[0002] In order to facilitate water collection, more and more drinking water barrels are now equipped with water outlet valves. The water outlet valves are usually installed on the lower side of the drinking water barrel body. In this way, when taking water, there is no need to turn the drinking water barrel upside down to let the water in the barrel flow out from the opening of the drinking water barrel. You only need to place the drinking water barrel forward and open the water outlet valve to get water.

[0003] At present, most domestic pure water processing companies have adopted highly automated assembly lines to produce bottled water. Due to the high cost of manufacturing barrels, companies usually recycle and reuse the barrels. Before the recycled barrels are filled with pure water again, the surface area, interior and water outlet valve of the drinking water barrels need to be cleaned and disinfected.

[0004] Since drinking water barrels equipped with water outlet valves are different from conventional drinking water barrels, this puts forward new requirements for the cleaning method of drinking water barrels. The common practice in the industry today for cleaning the water outlet valves of drinking water barrels is for workers on the production line to flush the water outlet valves of the buckets with handheld high-pressure water guns. This method requires a lot of manual work, has low flushing efficiency and high labor costs.

[0005] Therefore, in order to solve the problems of the technologies described above, it is extremely urgent to develop a cleaning device for the water outlet valve of a drinking water bucket. Utility Model Content

[0007] The technical effects to be achieved by the present invention are achieved through the following technical solutions:

[0009] Mounting rack;

[0010] A cleaning mechanism, mounted on the mounting frame;

[0012] The alignment mechanism includes an alignment sensing member for sensing the water outlet valve of the drinking water bucket;

[0013] The clamping assembly rotates after clamping the drinking water bucket, and the clamping assembly stops rotating after the alignment sensor senses the water outlet valve of the drinking water bucket, so that the water outlet valve of the drinking water bucket is aligned with the water outlet of the cleaning mechanism.

[0014] In some implementations, the barrel clamping mechanism further includes a lifting drive assembly, and the lifting drive assembly is disposed between the mounting frame and the connecting plate.

[0017] In this implementation, the output end of the rotary drive member is connected to the mounting shaft to drive the mounting shaft to rotate. The rotation of the mounting shaft drives the clamping structure to rotate, ensuring the reliability of the clamping assembly driving the drinking bucket to rotate.

[0018] In some implementations, the rotary drive member includes a rotor, a first right-angle gear, and a second right-angle gear, wherein the first right-angle gear is sleeved on the rotor, and the second right-angle gear is sleeved on the second end of the mounting shaft and meshes with the first right-angle gear.

[0019] In some implementations, the clamping structure includes a clamping jaw and a clamping driver, the clamping jaw is connected to the first end of the mounting shaft, and the clamping driver drives the clamping jaw to close or open.

[0020] In this implementation, when the external conveying mechanism conveys the drinking water bucket to the cleaning space, the clamping assembly descends under the drive of the lifting drive assembly, and the clamping drive drives the jaws to open so that the jaws are located on the periphery of the drinking water bucket, and then the clamping drive drives the jaws to close so that the jaws clamp and fix on the periphery of the drinking water bucket, thereby ensuring the reliability of the clamping structure in clamping the drinking water bucket.

[0021] In some implementations, the clamping jaw has at least two clamping arms, and the clamping drive member includes a clamping cylinder and a clamping piston rod. The clamping piston rod passes through the clamping cylinder, and both ends of the clamping piston rod are respectively connected to the clamping arms.

[0022] In some implementations, there are a plurality of clamping assemblies, and the plurality of clamping assemblies are rotatably connected to the connecting plate in sequence and at intervals.

[0023] In some implementations, the lifting drive assembly includes a first drive structure and a second drive structure, and the connecting plate is connected across the first drive structure and the second drive structure.

[0025] In this implementation method, the water source flows into several branch pipes through the main pipe and is then output from the water outlets of the branch pipes. The water outlets of the several branch pipes are set upward. Under the action of pressure, water is sprayed out from the water outlets of the several branch pipes, thereby flushing the water outlet valve of the drinking water barrel, thereby ensuring the reliability of the drinking water barrel water outlet valve cleaning device.

[0026] In some implementations, the alignment mechanism also includes a first clamping plate, a second clamping plate and a clamping drive member, the first clamping plate and the second clamping plate are arranged on both sides of the conveying direction of the drinking water bucket, and the clamping drive member drives the first clamping plate and the second clamping plate to approach or move away from the cleaning space.

[0027] In summary, the present invention has at least the following advantages:

[0028] The utility model provides a cleaning device for the water outlet valve of a drinking water bucket. The clamping component clamps the drinking water bucket and then rotates to drive the drinking water bucket to rotate. When the alignment sensing component senses the water outlet valve of the drinking water bucket, the clamping component stops rotating to stop the rotation of the drinking water bucket and fix it. At this time, the water outlet valve of the drinking water bucket and the water outlet of the cleaning mechanism are aligned with each other, so that the cleaning mechanism can flush the water outlet valve of the drinking water bucket, thereby realizing fully automatic cleaning of the water outlet valve of the drinking water bucket, with high cleaning efficiency and no need for manual operation, thereby reducing labor costs.

[0040] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1:

[0043] Please see the attached Figure 1 ~Attached Figure 2 The cleaning device of the water outlet valve of the drinking water bucket of the present invention comprises a mounting frame 1, a cleaning mechanism 2, a barrel clamping mechanism 3 and an alignment mechanism 4.

[0044] Please combine Figure 1 and Figure 2 , Figure 1 The diagram shows the structural relationship among the mounting frame 1, the cleaning mechanism 2, the barrel clamping mechanism 3 and the alignment mechanism 4 in the embodiment of the present invention. Figure 2 The diagram illustrates the specific structure of the barrel clamping mechanism 3 in an embodiment of the present invention. Specifically, the cleaning mechanism 2 is mounted on the mounting frame 1; the barrel clamping mechanism 3 is mounted on the mounting frame 1 and forms a cleaning space 21 with the cleaning mechanism 2. The barrel clamping mechanism 3 includes a connecting plate 31 and a clamping assembly 32. The connecting plate 31 is connected to the mounting frame 1, and the clamping assembly 32 is rotatably connected to a side of the connecting plate 31 adjacent to the cleaning space 21. The alignment mechanism 4 includes an alignment sensor 41 for sensing the position of the water outlet valve of the drinking water bucket. The clamping assembly 32 rotates after gripping the drinking water bucket. The alignment sensor 41 senses the water outlet valve of the drinking water bucket, and the clamping assembly 32 stops rotating after the clamping assembly 32 stops rotating, thereby aligning the water outlet valve of the drinking water bucket with the water outlet of the cleaning mechanism 2.

[0045] In this embodiment, an external conveying mechanism transports the drinking water bucket to the cleaning space 21. The clamping assembly 32 clamps the drinking water bucket and rotates, thereby driving the drinking water bucket to rotate. After the alignment sensor 41 senses the water outlet valve of the drinking water bucket, the clamping assembly 32 stops rotating, causing the drinking water bucket to stop rotating. At this time, the water outlet valve of the drinking water bucket is aligned with the water outlet of the cleaning mechanism 2, allowing the cleaning mechanism 2 to flush the water outlet valve of the drinking water bucket. Specifically, after the water outlet valve of the drinking water bucket is aligned with the water outlet of the cleaning mechanism 2, the cleaning mechanism 2 is opened, and the water outlet of the cleaning mechanism 2 sprays clean water or a cleaning solution or other medium to flush the water outlet valve of the drinking water bucket, thereby achieving the purpose of automatically cleaning the water outlet valve of the drinking water bucket. After the flushing is completed, the clamping component 32 releases the drinking water bucket, and the external conveying mechanism outputs the drinking water bucket from the cleaning space 21 to the next workstation; the clamping component 32 clamps the next drinking water bucket with a water outlet valve to be cleaned, and the clamping component 32, the alignment sensor 41 and the cleaning mechanism 2 repeat the above actions to achieve fully automatic cleaning of the water outlet valve of the drinking water bucket, with high cleaning efficiency and reduced labor cost investment.

[0046] Preferably, the alignment sensor 41 is mounted above the cleaning mechanism 2. Thus, when the clamping assembly 32 rotates and thereby drives the drinking bucket to rotate, the alignment sensor 41 senses the drinking bucket's outlet valve and the drinking bucket immediately stops rotating, ensuring that the drinking bucket's outlet valve is precisely aligned with the cleaning mechanism 2, thereby ensuring effective cleaning of the drinking bucket's outlet valve while also reducing water waste. The alignment sensor 41 can be a sensor.

[0047] In the above-mentioned cleaning device for the water outlet valve of the drinking water bucket, the clamping component 32 clamps the drinking water bucket and rotates to drive the drinking water bucket to rotate. When the alignment sensor 41 senses the water outlet valve of the drinking water bucket, the clamping component 32 stops rotating to stop the rotation of the drinking water bucket and fix it. At this time, the water outlet valve of the drinking water bucket and the water outlet of the cleaning mechanism 2 are aligned with each other, so that the cleaning mechanism 2 can flush the water outlet valve of the drinking water bucket, thereby realizing fully automatic cleaning of the water outlet valve of the drinking water bucket, with high cleaning efficiency and no need for manual operation, thereby reducing labor costs.

[0048] In some preferred embodiments, please continue to see Figure 2 , Figure 2 The diagram illustrates the structural relationship between the lifting drive assembly 33, the mounting frame 1, and the connecting plate 31 in an embodiment of the present invention. Specifically, the barrel clamping mechanism 3 also includes the lifting drive assembly 33, which is disposed between the mounting frame 1 and the connecting plate 31. The lifting drive assembly 33 drives the connecting plate 31 up and down, thereby driving the clamping assembly 32 up and down. The clamping assembly 32 descends, clamping the drinking bucket. The lifting drive assembly 33 then drives the clamping assembly 32 upward, thereby raising the drinking bucket. After the drinking bucket is raised, the clamping assembly 32 begins to rotate, rotating the drinking bucket until it aligns with the cleaning mechanism 2. After the cleaning mechanism 2 cleans the drinking bucket's outlet valve, the lifting drive assembly 33 drives the clamping assembly 32 downward, lowering the drinking bucket. This stabilizes the drinking bucket on the external conveying mechanism, preventing friction and wear between the bottom of the drinking bucket and the external conveying mechanism when the drinking bucket rotates. Preferably, the external conveying mechanism can be a conveyor line that passes through the cleaning space 21 and is located below the barrel clamping mechanism 3.

[0049] Example 2:

[0050] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the cleaning device of the water outlet valve of the drinking water bucket of the utility model. Figure 3 ~Attached Figure 5 .

[0051] Among them, see Figure 3 , Figure 3 The diagram illustrates the structural relationship between the mounting shaft 321, bearing 322, clamping structure 323, and rotary drive member 324 in an embodiment of the present invention. Specifically, the clamping assembly 32 includes the mounting shaft 321, bearing 322, clamping structure 323, and rotary drive member 324. The mounting shaft 321 passes through the connecting plate 31, the bearing 322 is sleeved on the mounting shaft 321 and abuts the connecting plate 31, the clamping structure 323 is connected to the first end of the mounting shaft 321, and the rotary drive member 324 drives the mounting shaft 321 to rotate.

[0052] In this embodiment, the output end of the rotary drive member 324 is connected to the mounting shaft 321 to drive the mounting shaft 321 to rotate. The rotation of the mounting shaft 321 drives the clamping structure 323 to rotate, ensuring the reliability of the clamping assembly 32 in rotating the drinking bucket. The bearing 322 is sleeved onto the mounting shaft 321, reducing the resistance encountered by the mounting shaft 321 during rotation, thereby enabling smoother rotation of the clamping structure 323 and improving the stability of the connection between the mounting shaft 321 and the connecting plate 31, thereby making the overall structure more compact. Preferably, the bearing 322 sleeves onto the mounting shaft 321 and abuts against both sides of the connecting plate 31.

[0053] In some preferred embodiments, the rotary drive member 324 includes a rotor 3241, a first right-angle gear 3242, and a second right-angle gear 3243. The first right-angle gear 3242 is sleeved on the rotor 3241, and the second right-angle gear 3243 is sleeved on the second end of the mounting shaft 321 and meshes with the first right-angle gear 3242. The first right-angle gear 3242 and the second right-angle gear 3243 cooperate to enable the rotary drive member 324 to drive the mounting shaft 321 to rotate. This cooperation ensures that the mounting shaft 321 is driven to rotate while also reducing the space occupied by the rotary drive member 324. This results in a smaller footprint for the rotary drive member 324 within the clamping assembly 32, a simpler structure, and improved assembly convenience.

[0054] In some preferred embodiments, the clamping structure 323 includes a clamping jaw 3231 and a clamping driver 3232. The clamping jaw 3231 is connected to the first end of the mounting shaft 321, and the clamping driver 3232 drives the clamping jaw 3231 to retract or open. When an external conveying mechanism transports the drinking bucket to the cleaning space 21, the clamping assembly 32 is lowered by the lifting driver 33. The clamping driver 3232 drives the clamping jaw 3231 to open, positioning the clamping jaw 3231 around the outer periphery of the drinking bucket. The clamping driver 3232 then drives the clamping jaw 3231 to retract, clamping and securing the clamping jaw 3231 around the outer periphery of the drinking bucket, thereby ensuring that the clamping structure 323 can reliably clamp the drinking bucket. Preferably, the specific position where the clamp 3231 clamps the drinking bucket is the water outlet section on the upper part of the drinking bucket. Since the cross-sectional diameter of the water outlet section is smaller than the cross-sectional diameter of the drinking bucket body, it is easier for the clamp 3231 to clamp. In this way, the volume of the clamping assembly 32 can also be reduced, thereby reducing the space occupied by the overall structure.

[0055] In some preferred embodiments, see Figure 4 , Figure 4The diagram illustrates the structural relationship between the clamping arms 323a and the clamping actuator 3232 in an embodiment of the present invention. Specifically, the clamping jaw 3231 comprises at least two clamping arms 323a. The clamping actuator 3232 includes a clamping cylinder 323b and a clamping piston rod 323c. The clamping piston rod 323c is disposed within the clamping cylinder 323b and connected at both ends to the clamping arms 323a. The clamping cylinder 323b drives the clamping piston rod 323c to extend and retract, thereby moving the at least two clamping arms 323a toward or away from each other. When the at least two clamping arms 323a approach, the clamping jaw 3231 clamps the drinking bucket. When the at least two clamping arms 323a move away from each other, the clamping jaw 3231 releases the drinking bucket. It is understandable that the number of clamping arms 323a can be increased or decreased according to actual operational requirements so that the clamping force generated by the clamping claw 3231 is adapted to the weight of the drinking bucket, thereby ensuring the reliability of the clamping claw 3231 in clamping the drinking bucket.

[0056] In some preferred embodiments, a plurality of clamping assemblies 32 are provided, and the plurality of clamping assemblies 32 are sequentially and rotatably connected to the connecting plate 31. The plurality of clamping assemblies 32 can simultaneously clamp and rotate a plurality of drinking water buckets in a one-to-one correspondence, thereby improving the cleaning efficiency of the water outlet valve of the drinking water bucket.

[0057] In some more preferred embodiments, see Figure 5 , Figure 5 The diagram illustrates the structural relationship between the connecting plate 31, the first drive structure 331, and the second drive structure 332 in one embodiment of the present invention. Specifically, the lifting drive assembly 33 comprises the first drive structure 331 and the second drive structure 332, with the connecting plate 31 connecting across the first and second drive structures 331 and 332. This ensures the balance and stability of the clamping assembly 32 when the lifting drive assembly 33 is raised and lowered, preventing the clamping assembly 32 from tilting during the lifting process, which could cause the water outlet valve of the drinking bucket to misalign with the water outlet of the cleaning mechanism 2.

[0058] Example 3:

[0059] The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the cleaning device of the water outlet valve of the drinking water bucket of the utility model. Figure 6 , Figure 6 The diagram schematically illustrates the structural relationship between the main pipeline 22 and the plurality of branch pipelines 23 in an embodiment of the present utility model.

[0060] Among them, the cleaning mechanism 2 includes a main pipe 22 and several branch pipes 23. The water inlet of the main pipe 22 is connected to the external water source, the water inlets of the several branch pipes 23 are connected to the water outlet of the main pipe 22, and the water outlets of the several branch pipes 23 are arranged upward.

[0061] In this embodiment, water flows through the main pipe 22 into the plurality of branch pipes 23 and is then discharged from the outlets of the branch pipes 23. The outlets of the plurality of branch pipes 23 are positioned upward, and under the action of pressure, water is ejected from the outlets of the plurality of branch pipes 23, thereby flushing the water outlet valve of the drinking water bucket, thereby ensuring the reliability of the drinking water bucket outlet valve cleaning device. It will be understood that the outlets of the plurality of branch channels are respectively arranged in a one-to-one correspondence with the plurality of clamping assemblies 32, so that the water outlet valve of the drinking water bucket and the water outlets of the branch channels are aligned with each other. It should be noted that the water inlet of the main channel is not limited to connecting to an external water source, but can also connect to other media sources used to clean and / or disinfect the water outlet valve of the drinking water bucket.

[0062] In some preferred embodiments, the alignment mechanism 4 further includes a first clamping plate 42, a second clamping plate 43, and a clamping driver 44. The first clamping plate 42 and the second clamping plate 43 are disposed on either side of the drinking water bucket in the conveying direction. The clamping driver 44 drives the first clamping plate 42 and the second clamping plate 43 toward or away from the cleaning space 21. After the water outlet valve of the drinking water bucket and the water outlet of the cleaning mechanism 2 are aligned, the clamping driver 44 drives the first clamping plate 42 and the second clamping plate 43 to simultaneously approach and clamp the drinking water bucket, thereby preventing the drinking water bucket from shifting during the cleaning process, which could result in incomplete cleaning of the water outlet valve.

[0063] In the cleaning device for the water outlet valve of a drinking water bucket of the present invention, the clamping component 32 clamps the drinking water bucket and rotates to drive the drinking water bucket to rotate. When the alignment sensor 41 senses the water outlet valve of the drinking water bucket, the clamping component 32 stops rotating to stop the rotation of the drinking water bucket and fix it. At this time, the water outlet valve of the drinking water bucket and the water outlet of the cleaning mechanism 2 are aligned with each other, so that the cleaning mechanism 2 can flush the water outlet valve of the drinking water bucket, thereby realizing fully automatic cleaning of the water outlet valve of the drinking water bucket, with high cleaning efficiency and no need for manual operation, thereby reducing labor costs.
