Description

Technical Field

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

[0002] 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.

[0003] When cleaning the water outlet valve of a drinking water bucket, the water outlet valve needs to be aligned with the water outlet of the flushing mechanism to ensure effective cleaning of the water outlet valve of the drinking water bucket; however, in the actual operation process of cleaning the water outlet valve of the drinking water bucket, the water outlet valve of the drinking water bucket is often not positioned accurately, resulting in the water outlet valve and the water outlet cannot be accurately aligned, thereby causing the water outlet valve to not be cleaned properly, affecting the reuse of the drinking water bucket.

[0004] Therefore, in order to solve the above-mentioned technical problems, it is extremely urgent to develop a positioning device for a water outlet valve of a drinking bucket. Utility Model Content

[0005] In order to solve the deficiencies of the prior art, the utility model provides a positioning device for a water outlet valve of a drinking water bucket, which avoids the problem of inaccurate positioning between the water outlet valve of the drinking water bucket and the external flushing outlet, thereby causing the water outlet valve of the drinking water bucket to not be cleaned properly.

[0006] The technical effects to be achieved by the present invention are achieved through the following technical solutions:

[0007] The utility model provides a positioning device for a water outlet valve of a drinking water bucket, comprising:

[0008] transmission channel;

[0009] A rotating clamping mechanism is provided above the transmission channel and is used to clamp the drinking water bucket and rotate it;

[0010] A sensing mechanism for sensing the position of a water outlet valve of a drinking water bucket; and

[0011] The water outlet valve positioning mechanism includes a calibration component, a positioning drive component, and a first positioning plate and a second positioning plate respectively provided on both sides of the transmission channel, wherein the calibration component is connected to a side of the first positioning plate close to the transmission channel;

[0012] Among them, after the sensing mechanism senses the position of the water outlet valve of the drinking water bucket, the rotating clamping mechanism stops rotating, the positioning drive component drives the first positioning plate and the second positioning plate to approach and clamp the drinking water bucket, and the calibration component is clamped on the water outlet valve of the drinking water bucket to achieve positioning of the water outlet valve of the drinking water bucket and the external flushing outlet.

[0013] In some implementations, the calibration assembly includes a calibration plate connected to the first positioning plate, and the calibration plate is provided with a calibration groove for clamping the water outlet valve of the drinking bucket.

[0014] In this implementation, the calibration groove of the calibration plate is clamped to the water outlet valve of the drinking bucket to achieve fixed positioning of the water outlet valve of the drinking bucket, thereby ensuring the accuracy of positioning between the water outlet valve of the drinking bucket and the external flushing outlet.

[0015] In some implementations, a limiting groove is provided on a side of the first positioning plate close to the drinking water bucket, and the calibration groove is located in the middle of the limiting groove.

[0016] In some implementations, the positioning device of the water outlet valve of the drinking bucket further includes a valve opening mechanism, which is connected to the upper portion of the calibration component and is disposed toward the transmission channel.

[0017] In this implementation, when the first positioning plate approaches the transmission channel and drives the calibration component to be clamped on the water outlet valve of the drinking bucket, the valve opening mechanism will abut against the valve opening handle of the water outlet valve of the drinking bucket, so that the water outlet valve of the drinking bucket is in an open state; when the first positioning plate is away from the transmission channel, the valve opening mechanism will release the state of abutting against the valve opening handle of the water outlet valve of the drinking bucket, and at this time the water outlet valve of the drinking bucket is closed.

[0018] In some implementations, the valve opening mechanism includes a connecting portion and an abutting portion, the connecting portion is connected to the upper portion of the calibration component, one end of the abutting portion is connected to the connecting portion, and the other end is used to abut the valve opening handle of the water outlet valve of the drinking bucket.

[0019] In some implementations, the abutment portion has an inclined guide surface.

[0020] In this implementation, the guide surface ensures that the abutment part abuts smoothly against the valve opening handle of the water outlet valve of the drinking bucket, and increases the abutment area between the abutment part and the valve opening handle of the water outlet valve of the drinking bucket, thereby ensuring the reliability of the abutment part in opening the water outlet valve of the drinking bucket.

[0021] In some implementations, the positioning drive assembly includes a positioning cylinder having a piston rod, wherein a free end of the piston rod is connected to a side of the first positioning plate and / or the second positioning plate facing away from the transmission channel.

[0022] In some implementations, the rotary clamping mechanism includes a mounting plate and a clamping assembly, the mounting plate is located above the transmission channel, and the clamping assembly is rotatably connected to a side of the mounting plate close to the transmission channel.

[0023] In this implementation, the clamping assembly clamps the drinking bucket and rotates relative to the mounting plate, thereby driving the drinking bucket to rotate relative to the sensing mechanism. When the sensing mechanism senses the position of the water outlet valve of the drinking bucket, the clamping assembly stops rotating and the drinking bucket stops rotating, ensuring the reliability of the calibration assembly being connected to the water outlet valve of the drinking bucket.

[0024] In some implementations, there are a plurality of the clamping assemblies, and the plurality of the clamping assemblies are rotatably connected to the mounting plate at intervals.

[0025] In some implementations, the rotary clamping mechanism further includes a plurality of rotary driving members, and the plurality of rotary driving members respectively drive the plurality of clamping assemblies in a one-to-one correspondence.

[0026] In summary, the present invention has at least the following advantages:

[0027] The utility model provides a positioning device for a water outlet valve of a drinking water bucket, wherein a calibration component is connected to a side of a first positioning plate close to a transmission channel. When the positioning drive component respectively drives the first positioning plate and the second positioning plate close to the transmission channel and clamps the drinking water bucket, the first positioning plate clamps the drinking water bucket and at the same time the calibration component is clamped on the water outlet valve of the drinking water bucket, so that the water outlet valve of the drinking water bucket is fixed and positioned with an external flushing outlet, thereby avoiding the problem of inaccurate positioning between the water outlet valve of the drinking water bucket and the external flushing outlet, which causes the water outlet valve of the drinking water bucket to not be cleaned properly.

[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 positioning device of the water outlet valve of the drinking water bucket of the present invention includes a transmission channel 1, a rotating clamping mechanism 2, a sensing mechanism 3 and a water outlet valve positioning mechanism 4.

[0044] Please combine Figure 1 and Figure 2 , Figure 1 The diagram shows the structural relationship among the transmission channel 1, the rotary clamping mechanism 2, the sensing mechanism 3 and the water outlet valve positioning mechanism 4 in the embodiment of the present utility model. Figure 2The diagram illustrates the specific structure of the water outlet valve positioning mechanism 4 in an embodiment of the present invention. Specifically, a rotating clamping mechanism 2 is disposed above the transmission channel 1, used to clamp and rotate the drinking bucket. A sensing mechanism 3 is used to sense the position of the drinking bucket's water outlet valve. The water outlet valve positioning mechanism 4 includes a calibration assembly 41, a positioning drive assembly 42, and a first positioning plate 43 and a second positioning plate 44, respectively disposed on either side of the transmission channel 1. The calibration assembly 41 is connected to the side of the first positioning plate 43 closest to the transmission channel 1. After the sensing mechanism 3 senses the position of the drinking bucket's water outlet valve, the rotating clamping mechanism 2 stops rotating, the positioning drive assembly 42 drives the first positioning plate 43 and the second positioning plate 44 to approach and clamp the drinking bucket, and the calibration assembly 41 engages the drinking bucket's water outlet valve, thereby achieving positioning of the drinking bucket's water outlet valve and the external flushing outlet.

[0045] In this embodiment, the drinking water bucket is transported to the transmission channel 1 via an external conveying mechanism, so that the rotating clamping assembly 22 located above the transmission channel 1 clamps the drinking water bucket. The rotating clamping assembly 22 rotates, thereby driving the drinking water bucket to rotate. When the sensing mechanism 3 senses the drinking water bucket outlet valve, the rotating clamping assembly 22 stops rotating, thereby stopping the drinking water bucket. The positioning drive assembly 42 respectively drives the first positioning plate 43 and the second positioning plate 44 toward the transmission channel 1, thereby clamping the drinking water bucket. Because the calibration assembly 41 is connected to the first positioning plate 43, when the first positioning plate 43 moves toward the transmission channel 1, it simultaneously drives the calibration assembly 41 toward the transmission channel 1, allowing the calibration assembly 41 to engage with the drinking water bucket outlet valve, thereby securing the drinking water bucket outlet valve. This, in turn, allows the drinking water bucket outlet valve and the external flushing outlet to achieve precise fixed positioning, ensuring reliable positioning and cleaning of the drinking water bucket outlet valve. Preferably, the sensing mechanism 3 is located above the calibration assembly 41 and is a sensor.

[0046] It can be understood that when the sensing mechanism 3 senses the position of the water outlet valve of the drinking water bucket, and the rotating clamping component 22 has a slight deviation in the process of stopping rotation, the position of the water outlet valve of the drinking water bucket and the distance between the external flushing water outlet will also have a slight deviation, and accurate alignment cannot be achieved. At this time, since the calibration component 41 is connected to the first positioning plate 43, when the first positioning plate 43 and the second positioning plate 44 are respectively close to the drinking water bucket, the calibration component 41 can calibrate the position of the water outlet valve of the drinking water bucket, thereby avoiding the problem of inaccurate positioning with the external flushing water outlet caused by deviation in the position of the water outlet valve of the drinking water bucket.

[0047] The above-mentioned positioning device of the drinking water bucket water outlet valve, the calibration component 41 is connected to the side of the first positioning plate 43 close to the transmission channel 1. When the positioning drive component 42 respectively drives the first positioning plate 43 and the second positioning plate 44 close to the transmission channel 1 and clamps the drinking water bucket, the first positioning plate 43 clamps the drinking water bucket while the calibration component 41 is clamped to the drinking water bucket water outlet valve, so that the drinking water bucket water outlet valve is fixed and positioned with the external flushing outlet, avoiding the problem of inaccurate positioning between the drinking water bucket water outlet valve and the external flushing outlet, which causes the drinking water bucket water outlet valve to not be cleaned properly.

[0048] In some preferred embodiments, please continue to see Figure 2 , Figure 2 The diagram illustrates the structural relationship between the calibration slot 412 and the drinking bucket's outlet valve in an embodiment of the present invention. Specifically, the calibration assembly 41 includes a calibration plate 411 connected to a first positioning plate 43. Calibration plate 411 defines a calibration slot 412 for engaging the drinking bucket's outlet valve. The movement of the first positioning plate 43 drives the movement of the calibration plate 411. When the first positioning plate 43 approaches the transmission channel 1 and clamps the drinking bucket, the calibration slot 412 of the calibration plate 411 engages with the drinking bucket's outlet valve, securing the valve and ensuring accurate positioning between the drinking bucket's outlet valve and the external flushing outlet.

[0049] In some more preferred embodiments, a limiting groove 431 is defined on the side of the first positioning plate 43 proximal to the water bucket, and the calibration groove 412 is located in the middle of the limiting groove 431. When the first positioning plate 43 approaches the transmission channel 1 and clamps the water bucket, the limiting groove 431 limits the water bucket, making the first positioning plate 43 more stable when clamping the water bucket, thereby ensuring that the calibration groove 412 is more secure when engaging the water outlet valve of the water bucket. Since the calibration groove 412 is located in the middle of the limiting groove 431, the calibration groove 412 further ensures the reliability of calibrating the water outlet valve of the water bucket.

[0050] Example 2:

[0051] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the positioning device of the water outlet valve of the drinking water bucket of the utility model. Figure 3 ~Attached Figure 5 .

[0052] Please combine Figure 3 and Figure 4 , Figure 3 and Figure 4 The diagram shows the structural relationship between the valve opening mechanism 5 and the calibration assembly 41 in the embodiment of the present invention. Specifically, the positioning device of the water outlet valve of the drinking bucket also includes a valve opening mechanism 5, which is connected to the upper part of the calibration assembly 41 and is arranged toward the transmission channel 1.

[0053] In this embodiment, when the first positioning plate 43 approaches the transmission channel 1 and thereby drives the calibration assembly 41 to engage with the drinking bucket outlet valve, the valve opening mechanism 5 located above the calibration assembly 41 abuts against the valve opening handle of the drinking bucket outlet valve, causing the drinking bucket outlet valve to be in an open state, facilitating external flushing of the water outlet to clean the interior of the drinking bucket outlet valve. When the first positioning plate 43 moves away from the transmission channel 1 and thereby drives the calibration assembly 41 to release the engagement with the drinking bucket outlet valve, the valve opening mechanism 5 further releases the engagement with the valve opening handle of the drinking bucket outlet valve, closing the drinking bucket outlet valve, facilitating external flushing of the water outlet to clean the exterior of the drinking bucket outlet valve, thereby ensuring the reliability of the overall structure. It should be noted that the switch handle of the drinking bucket outlet valve is located above the drinking bucket outlet valve.

[0054] In some preferred embodiments, the valve opening mechanism 5 includes a connecting portion 51 and an abutting portion 52. The connecting portion 51 is connected to the upper portion of the calibration assembly 41. One end of the abutting portion 52 is connected to the connecting portion 51, and the other end is used to abut the valve opening handle of the water outlet valve of the drinking bucket. The connecting portion 51 is connected between the calibration assembly 41 and the abutting portion 52. When the calibration assembly 41 approaches the transmission channel 1, it simultaneously drives the connecting portion 51 and the abutting portion 52 toward the transmission channel 1, so that the abutting portion 52 abuts the valve opening handle of the water outlet valve of the drinking bucket, thereby opening the water outlet valve of the drinking bucket, facilitating the external flushing of the water outlet to clean the interior of the water outlet valve of the drinking bucket. When the calibration assembly 41 moves away from the transmission channel 1, the abutting portion 52 releases the abutting state of the valve opening handle of the water outlet valve of the drinking bucket, closing the water outlet valve of the drinking bucket, facilitating the external flushing of the water outlet to clean the exterior of the water outlet valve of the drinking bucket.

[0055] In some preferred embodiments, the abutment portion 52 has an inclined guide surface 521. This ensures that the abutment portion 52 smoothly abuts the opening handle of the water bucket outlet valve and increases the contact area between the abutment portion 52 and the opening handle, thereby ensuring the reliability of the abutment portion 52 in opening the water bucket outlet valve. Furthermore, the guide surface 521 is inclined in the same direction as the opening handle of the water bucket outlet valve in the closed state, further enhancing the reliability of the abutment portion 52 abutting the opening handle of the water bucket outlet valve. Specifically, the guide surface 521 is inclined upward toward the transmission channel 1.

[0056] In some more preferred embodiments, see Figure 5 , Figure 5The diagram illustrates the structural relationship between the positioning cylinder 421, piston rod 422, and first positioning plate 43 in an embodiment of the present invention. Specifically, the positioning drive assembly 42 includes a positioning cylinder 421 having a piston rod 422. The free end of the piston rod 422 is connected to the side of the first positioning plate 43 and / or the second positioning plate 44 facing away from the transmission channel 1. The positioning cylinder 421 drives the piston rod 422 to extend and retract, thereby driving the first positioning plate 43 and / or the second positioning plate 44 toward or away from the transmission channel 1, ensuring the reliability of the first positioning plate 43 and / or the second positioning plate 44 clamping the drinking bucket, thereby ensuring the reliability of the calibration assembly 41 calibrating the position of the drinking bucket outlet valve, and further ensuring the reliability of the valve opening mechanism 5 abutting the valve opening handle of the drinking bucket outlet valve.

[0057] Example 3:

[0058] The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the positioning device of the water outlet valve of the drinking water bucket of the utility model. Figure 6 , Figure 6 The figure shows the structural relationship between the mounting plate 21 and the clamping assembly 22 in the embodiment of the present invention.

[0059] The rotary clamping mechanism 2 includes a mounting plate 21 and a clamping assembly 22 . The mounting plate 21 is located above the transmission channel 1 . The clamping assembly 22 is rotatably connected to a side of the mounting plate 21 close to the transmission channel 1 .

[0060] In this embodiment, the clamping assembly 22 clamps the drinking water bucket and rotates relative to the mounting plate 21, thereby driving the drinking water bucket to rotate relative to the sensing mechanism 3. When the sensing mechanism 3 senses the position of the water outlet valve of the drinking water bucket, the clamping assembly 22 stops rotating and the drinking water bucket stops rotating, thereby ensuring the reliability of the calibration assembly 41 being connected to the water outlet valve of the drinking water bucket.

[0061] In some preferred embodiments, multiple clamping assemblies 22 are provided, each rotatably connected to the mounting plate 21 at intervals. This allows the multiple clamping assemblies 22 to simultaneously and individually clamp multiple drinking water buckets, thereby improving the cleaning efficiency of the drinking water bucket outlet valves. It will be appreciated that multiple calibration assemblies 41 and valve opening mechanisms 5 are provided in a one-to-one correspondence with each of the multiple clamping assemblies 22.

[0062] In some more preferred embodiments, the rotary clamping mechanism 2 further includes a plurality of rotary drive members 23, each of which drives a corresponding plurality of clamping assemblies 22. This allows the rotary drive members 23 to output a stronger driving force, thereby improving the reliability of the clamping assembly 22 in driving the water bucket to rotate. This also avoids the problem of the plurality of clamping assemblies 22 ceasing to operate if the rotary drive members 23 malfunction.

[0063] The positioning device of the water outlet valve of the drinking water bucket of the present invention, the calibration component 41 is connected to the side of the first positioning plate 43 close to the transmission channel 1, when the positioning drive component 42 respectively drives the first positioning plate 43 and the second positioning plate 44 to approach the transmission channel 1 and clamp the drinking water bucket, the first positioning plate 43 clamps the drinking water bucket and at the same time the calibration component 41 is clamped to the water outlet valve of the drinking water bucket, so that the water outlet valve of the drinking water bucket is fixed and positioned with the external flushing outlet, avoiding the problem of inaccurate positioning between the water outlet valve of the drinking water bucket and the external flushing outlet, which causes the water outlet valve of the drinking water bucket to not be cleaned properly.
