[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-9 The present invention provides a fully automatic liquid dispensing device for wet wipes, including a conveying mechanism, a liquid dispensing mechanism, a flipping mechanism and a positioning and separation mechanism;

[0033] The conveying mechanism includes a conveyor frame 1, a conveyor belt 2, and a drive motor 3. The conveyor frame 1 is equipped with two parallel conveyor belts 2, which are synchronously driven by the drive motor 3. There is a gap between the two conveyor belts 2. The drive motor 3 drives the conveyor belts 2 to rotate, which in turn drives the wet wipes to be conveyed backward. When the wet wipes are conveyed to a set position, the conveying stops. Since it is a cyclic conveying, the set position can be obtained by testing the trajectory in advance, or it can be achieved by using a position sensor in conjunction with servo control. In this invention, it is preferred to obtain the position by testing in advance.

[0034] The liquid dispensing mechanism includes guide rails, with two guide rails arranged at the front and rear, namely a front guide rail 4 and a rear guide rail 5. The two guide rails are fixed above the conveying mechanism by an external frame and are perpendicular to its conveying direction. The front guide rail 4 is equipped with a first front slide block 6 and a second front slide block 7 that can be driven to slide, and the rear guide rail 5 is equipped with a first rear slide block 8 and a second rear slide block 9 that can be driven to slide. The first front slide block 6 and the first rear slide block 8 are front-to-back, and the second front slide block 7 and the second rear slide block 9 are front-to-back. A first liquid dispensing mechanism 10 and a second liquid dispensing mechanism 11 are respectively installed between the first front slide block 6 and the first rear slide block 8 and between the second front slide block 7 and the second rear slide block 9. Thus, by driving the first front slide block 6 and the first rear slide block 8 and the second front slide block 7 and the second rear slide block 9 to move, it is convenient to adjust the position of the first liquid dispensing mechanism 10 and the second liquid dispensing mechanism 11 relative to the conveyor belt 2, and further realize the alternating clamping and dispensing of liquid from wet wipes.

[0035] The liquid adding mechanism includes a connecting seat 12 that is fixedly connected to the first front slide 6, the second front slide 7, the first rear slide 8, and the second rear slide 9 respectively. A connecting rod 13 is installed between two corresponding connecting seats 12. Multiple sets of spraying devices 14 are sequentially and spaced on the connecting rod 13. By setting the connecting rod 13, the position of the spraying device 14 can be adjusted in advance and then fixed as needed to meet different interval requirements.

[0036] The flipping mechanism includes four third guide rails 15, each equipped with a synchronous belt and a reduction motor 16 driving its up-and-down movement. Four connecting seats 12 are fixedly connected to the synchronous belts of the four third guide rails 15. Mounting plates 17 are fixed to the bottom ends of two corresponding third guide rails 15. Synchronous flipping motors 18 are fixed to the outer sides of each mounting plate 17. A flipping plate 19 is fixed to the mounting plate 17 via a rotating shaft, which is fixedly connected to the output end of the synchronous flipping motor 18 via a coupling. The flipping plate 19 has opposing first clamps 20 and second clamps 21 at both ends. Connecting heads 22 are provided at both ends of the first clamps 20. Each connecting head 22 has a slot that can hold the head of the flipping plate 19. The head of the flipping plate 19 located within the slot has two positioning holes 23. Pins 24 corresponding to the positioning holes 23 are mounted on the connecting head 22. The outer ends of the two pins 24 are connected by baffles. 25. Fixed connection, the first clamp 20 and the second clamp 21 are each equipped with multiple sets of elastic clamps at intervals, and the elastic clamps on the two clamps are arranged opposite to each other; the reduction motor 16 of the corresponding flipping mechanism drives the synchronous belt to move. Since the relative position of the connecting seat 12 and the slide remains unchanged, the third guide rail 15 can be driven to descend. The reduction motor 16 drives the third guide rail 15 and the entire flipping mechanism to rise. After the position is appropriate, the synchronous flipping motor 18 drives the flipping plate 19 and the first clamp 20 and the second clamp 21 to flip. Then the spraying device 14 on it sprays the corresponding wet wipes. The spray volume during the spraying can be precisely controlled. At the same time, during the spraying, the wet wipes can be flipped by the flipping mechanism, and the entire flipping mechanism can perform lifting and lowering movements. By testing the lifting and lowering trajectory in advance, it can be ensured that the relative height with the spray head is always maintained during the spraying, avoiding the influence caused by the different heights of the wet wipes from the spray head when rotating, and achieving high-precision spraying and liquid addition.

[0037] The positioning and separation mechanism is arranged in two sets, each including a positioning cylinder 26, a displacement cylinder 27, a positioning plate 28, and a finger cylinder 29. The positioning cylinder 26 is vertically arranged. The displacement cylinder 27 is mounted on the top output end of the positioning cylinder 26. The positioning plate 28 is mounted on the body of the displacement cylinder 27. A connecting plate 30 is mounted on the output end of the displacement cylinder 27. The finger cylinder 29 is mounted on the connecting plate 30 with an upward orientation. An openable and closable cylinder finger 31 is mounted on the output end of the finger cylinder 29. When it is necessary to pick up a wet wipe, the head end of the flip plate 19 that mates with the slot of the connector 22 faces downward. After it is in position, the head end of the flip plate 19 will be fully inserted into the slot of the connector 22. Then the finger cylinder 29 drives the cylinder finger. When the cylinder finger 31 opens, it can insert the pin 24 into the positioning hole at the head end of the flip plate 19 through the baffle 25. Then the cylinder finger 31 closes, and the five sets of wet wipes will be clamped between the upper and lower second clamps 21 and the first clamp 20, and held by the elastic clamps on the two clamps. When it is necessary to remove the wet wipes after adding liquid, the positioning groove 39 of the first clamp 20 is inserted into the positioning pin 38 and is accurately positioned. Then the finger cylinder 29 drives the cylinder finger 31 to open. The part of the cylinder finger 31 near the connector of the first clamp 20 presses against the first clamp 20, while the other part pulls the pin 24 out of the positioning hole of the flip plate 19 by pushing the baffle 25 outward, so that the first clamp 20 is disengaged from the flipping mechanism.

[0038] Please see Figure 1 The gap between the two conveyor belts 2 is greater than the width of the first clamp 20 and the second clamp 21. After the first clamp 20 and the second clamp 21 are placed flat on the positioning plate 28, their top surfaces are lower than the top surfaces of the conveyor belts 2. In this embodiment, the clamps can be placed between the two conveyor belts 2 without interference, and the top surfaces of the clamps do not interfere with the conveyor belts 2 driving the wet wipes to be transported above the clamps.

[0039] Please see Figure 1 Each of the spraying devices 14 includes multiple liquid spraying heads and a metering pump. In this embodiment, when the device is flipped, the spraying device 14 sprays the corresponding wet wipes, and the spraying volume during the spraying can be controlled individually and precisely.

[0040] Please see Figure 1 The flip plate 19 is symmetrically arranged at both ends. The first clamp 20 and the second clamp 21 have the same structure and are arranged opposite each other. In this embodiment, the first clamp 20 and the second clamp 21 have the same structural design, so the upper and lower positions of the first clamp 20 and the second clamp 21 can be replaced. This allows the wet wipe to be reversed when it is picked up from the spray and after it is put back into the spray. Since the wet wipe needs to be taken out, there are requirements for the upper and lower surfaces when packaging. The design that the upper and lower surfaces can be reversed after the wet wipe is put back can make the corresponding side face up as needed, which is convenient for subsequent packaging.

[0041] Please see Figure 6 The head end of the flip plate 19 is smaller than the size of the middle body, and a retaining groove 32 is formed between the head end and the middle body. In this embodiment, it is convenient for the head end of the flip plate 19 to be fully inserted into the slot of the connector 22 for positioning, as well as for the stability during the positioning process.

[0042] Please see Figure 8 Each set of elastic clamps includes multiple positioning rods 33. The top of each positioning rod 33 is provided with a clamp 34 with a diameter larger than the body. The clamp is provided with a positioning cylinder 35 through which the positioning rod 33 passes. The other end of the positioning rod 33 is provided with a stop 36. A buffer spring 37 is sleeved on the positioning rod 33 between the clamp 34 and the clamp. In this embodiment, the design of multiple clamps 34 facilitates the full clamping of the wet wipe while allowing the outer side of the wet wipe to open, which is conducive to the spray liquid entering the interior of the wet wipe and being fully absorbed. The design of the buffer spring 37 together achieves an elastic clamping effect.

[0043] Please see Figure 6 , Figure 10 The positioning and separation mechanism further includes a positioning pin 38 located on the positioning plate 28. The head of the positioning pin 38 is tapered. The outer sides of the first clamp 20 and the second clamp 21 are provided with positioning grooves 39 corresponding to the positioning pin 38. In this embodiment, the tapered head design of the positioning pin 38 facilitates insertion into the positioning groove 39. The cooperation between the positioning pin 38 and the positioning groove 39 can position the clamp when it is placed between the conveyor belts 2.

[0044] Please see Figure 10 The positioning separation mechanism also includes a positioning support frame 40, and the upper part of the positioning support frame 40 is provided with a positioning slot 41. In this embodiment, the positioning slot 41 can position the side of the clamp, further improving the positioning stability effect when the clamp is placed between the conveyor belts 2.

[0045] Please see Figure 1 The first front slide block 6 and the second front slide block 7 are driven by a synchronous belt on the front guide rail 4, and the first rear slide block 8 and the second rear slide block 9 are driven by a synchronous belt on the rear guide rail 5. The synchronous belts on the front guide rail 4 and the rear guide rail 5 are driven synchronously by a synchronous motor 42. In this embodiment, a synchronous motor 42 drives the slide blocks on the two guide rails to slide synchronously, thereby improving the synchronicity of sliding on both sides and improving the machining accuracy.

[0046] Please see Figure 4The pin 24 has a groove on one side, and a positioning bead 43 is installed in the groove. The positioning bead 43 is connected to the pin 24 through a compression spring located in the groove. The connector 22 has a positioning bead groove 44, which corresponds to the position of the positioning bead 43 after the pin 24 is fully inserted. The diameter of the positioning bead groove 44 is smaller than the diameter of the positioning bead 43. In this embodiment, when the pin 24 is separated from the flip plate 19, the positioning bead 43 will be squeezed back into the groove when the pin 24 is pulled out. When the pin 24 needs to position the flip plate 19, after it is fully inserted, the positioning bead 43 will be stuck in the positioning bead groove 44 under the action of the compression spring, so that the pin 24 is not easy to loosen and disengage when flipping. The design of the positioning bead groove 44 being smaller than the diameter of the positioning bead 43 prevents the positioning bead 43 from entering the positioning bead groove 44 and getting stuck.

[0047] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0048] Working principle: Before adding liquid, the first clamp 20 of the first liquid adding mechanism 10 corresponding to the flipping mechanism is placed in the interval between the two conveyor belts 2 and positioned by the positioning plate 28. The displacement cylinder 27 brings the finger cylinder 29 and the cylinder finger 31 to the outside of the baffle 25 on the pin 24. The spraying device 14 is preferably set in five groups. The stacked wet wipes are placed on the two conveyor belts 2 at the same interval as the spraying device. The wet wipes are multiple pieces stacked on top of each other and laid flat. It is not limited to wet wipes. It is also applicable to paper towels such as wet toilet paper that need to be added with liquid.

[0049] When adding liquid, the drive motor 3 drives the conveyor belt 2 to rotate, which in turn drives the wet wipes to be conveyed backward. When the wet wipes are conveyed to the set position, the conveying stops. Since it is a cyclic conveying, the set position can be obtained by testing the trajectory in advance, or it can be achieved by using a position sensor in conjunction with servo control. In this invention, it is preferred to obtain the position by testing in advance. After a batch of five sets of wet wipes are in place, the positioning cylinder 26 drives the positioning plate 28 to rise, which in turn drives the first clamp 20 to rise. The elastic clamp causes the wet wipes to rise and detach from the conveyor belt 2.

[0050] During this period, the geared motor 16 of the corresponding flipping mechanism drives the synchronous belt to move. Since the relative position of the connecting seat 12 and the slide remains unchanged, the third guide rail 15 can be driven to descend. During this period, the head end of the flipping plate 19 that cooperates with the slot of the connecting head 22 faces downward. After it is in place, the head end of the flipping plate 19 will be fully inserted into the slot of the connecting head 22. Then, the finger cylinder 29 drives the cylinder finger 31 to open. When the cylinder finger 31 opens, the pin 24 can be inserted into the positioning hole at the head end of the flipping plate 19 through the baffle 25. Then the cylinder finger 31 closes. At this time, the five sets of wet wipes will be clamped between the upper and lower second clamp 21 and the first clamp 20, and clamped by the elastic clamps on the two clamps.

[0051] The geared motor 16 drives the third guide rail 15 and the entire flipping mechanism to rise. After the position is appropriate, the synchronous flipping motor 18 drives the flipping plate 19 and the first clamp 20 and the second clamp 21 to flip. Then the spraying device 14 on it sprays the corresponding wet wipes. The spray volume during spraying can be precisely controlled. At the same time, the wet wipes can be flipped by the flipping mechanism during spraying. The entire flipping mechanism can also move up and down. By testing the lifting trajectory in advance, the relative height with the spray head can be maintained at all times during spraying. This avoids the influence caused by the different heights of the wet wipes from the spray head when rotating, and achieves high-precision spraying and liquid addition.

[0052] During the spraying and liquid addition process of the first liquid addition mechanism 10, the first front slide 6 and the first rear slide 8 are moved away by the synchronous motor 42. At the same time, the second front slide 7 and the second rear slide 9 move to the top of the conveyor belt 2. Then, the first clamp 20 on the second liquid addition mechanism 11 is moved downward to the conveyor belt 2. Before it reaches the position, the displacement cylinder 27 pulls the finger cylinder 29 inward to return it to its original position. After it reaches the position, the positioning groove 39 of the first clamp 20 is inserted into the positioning pin 38 and is precisely positioned. Then, the finger cylinder 29 drives the cylinder finger 31 to open. The part of the cylinder finger 31 near the connector of the first clamp 20 presses against the first clamp 20, while the other part pulls the pin 24 out of the positioning hole of the flip plate 19 by pushing the baffle 25 outward, so that the first clamp 20 is disengaged from the flip mechanism. The liquid addition process of the previous batch of five sets of wet wipes is repeated. The same principle is used to cycle the process, which can realize the fully automatic and precise processing of wet wipes.

[0053] The first clamp 20 and the second clamp 21 have the same structural design, so the upper and lower positions of the first clamp 20 and the second clamp 21 can be interchanged. This allows the wet wipe to be reversed when it is picked up from the spray and when it is put back into the spray. Since the wet wipe needs to be taken out, there are requirements for the upper and lower surfaces during packaging. The design that the upper and lower surfaces can be reversed after the wet wipe is put back can make the corresponding side face up as needed, which is convenient for subsequent packaging.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can 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.
