Description

Technical Field

[0001] This invention relates to the field of wet wipe production technology, specifically to a wet wipe production equipment. Background Technology

[0002] Wet wipes are disposable hygiene products made of pure water, spunlace nonwoven fabric and various additives, used for wiping the face, hands or skin. They have cleaning, disinfecting, antibacterial and moisturizing functions. Wet wipes are divided into high water content, medium water content and low water content types according to their water content. The higher the water content, the easier it is for the liquid in the wet wipe to be extracted.

[0003] A search revealed a patent publication number CN208773678U that proposes a non-woven fabric cutting device for producing wet wipes. In this patent document, the wet wipes are flattened and fixed before being squeezed and cut. Because wet wipes have a high moisture content, they are easily contaminated during the fixing process. However, existing equipment cannot promptly determine the contamination status of the wet wipes. Therefore, there is an urgent need for a wet wipe production device to solve this problem.

[0032] 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.

[0033] The present invention provides the following embodiments:

[0034] Example 1

[0035] This invention provides a wet wipe production equipment, such as... Figure 1 As shown, a conveying platform 1 is provided. A rotary cutting mechanism 2 is provided at the center of the conveying platform 1. A conveying roller assembly 11 is provided on the left side of the conveying platform 1. A conveying collection mechanism 5 and a hygiene testing and sampling mechanism 9 are provided sequentially on the right side of the conveying platform 1 along the direction of wet paper towel movement. The hygiene testing and sampling mechanism 9 is used to perform microbial sampling and testing on the stacked wet paper towels.

[0036] The sanitary testing and sampling mechanism 9 includes a traveling truss 91, which is bolted to the conveyor platform 1. A traveling platform 92 is slidably connected to the traveling truss 91. A lead screw 93 is threaded through and connected to the traveling platform 92. The two ends of the lead screw 93 are rotatably connected to the traveling truss 91. A lead screw motor is bolted to one side of the traveling truss 91. The output end of the lead screw motor is connected to the lead screw 93. An electric telescopic rod 94 is bolted to the bottom of the traveling platform 92. A probe sampling structure 10 is bolted to the working end of the electric telescopic rod 94. External disinfection structures 95 are provided on both sides of the traveling truss 91.

[0037] The preferred conveyor roller assembly 11 has its rotating seat bolted to the conveyor frame 1.

[0038] The working principle and beneficial effects of the above technical solution are as follows: the raw material of wet wipes is continuously conveyed through the conveyor roller group 11 on the left. The rotating seat of the conveyor roller group 11 is fixed on the conveyor frame 1 by bolts, which facilitates installation and debugging. The conveyor frame 1 serves as the main body of the equipment, providing support and positioning for each mechanism. When the conveyor roller group 11 conveys the wet wipes to the rotary cutting mechanism 2, the rotary cutting mechanism 2 uses the tension generated by the rotation to stretch and cut the wipes by rotating in opposite directions. The cut wet wipes are simultaneously clamped by the cutter structure 3 and fed into the conveying and collecting mechanism 5. The conveying and collecting mechanism 5 conveys the cut strips of wet wipes to the designated position and then stacks them gradually. The stacked wet wipes are sampled and tested by the hygiene testing and sampling mechanism 9 to determine the microbial content on the batch of wet wipes.

[0039] The lead screw 93 of the sanitary testing sampling mechanism 9 rotates in both directions on the traveling truss 91. Due to the threaded connection between the traveling platform 92 and the lead screw 93, the traveling platform 92 reciprocates along the traveling truss 91. The reciprocating motion of the traveling platform 92 drives the electric telescopic rod 94 to move. When it reaches the designated position, the electric telescopic rod 94 extends and retracts, and sampling is achieved through the probe sampling structure 10. The external disinfection structure 95 sterilizes and disinfects the outer surfaces of the electric telescopic rod 94 and the probe sampling structure 10 with ultraviolet light to avoid interference from external microorganisms.

[0040] This invention employs a rotary cutting mechanism 2 to cut wet wipes. This mechanism achieves cutting through counter-rotating at a uniform speed, reducing swaying during the cutting process, minimizing cutting length deviation, and ensuring high precision. Simultaneously, the tension generated by rotation during cutting stretches and cuts the wet wipes, reducing large-area contact and preventing excessive compression that could cause liquid seepage. The conveying and collecting mechanism 5 promptly conveys and stacks the cut wet wipes, ensuring production efficiency and reducing the risk of contamination during transport. Furthermore, the automatic stacking mechanism offers high precision. The hygiene testing and sampling mechanism 9 ensures online monitoring and sampling of the wet wipes, allowing for timely understanding of the hygiene status of each production batch. The traveling truss 91, lead screw 93, and traveling platform 92 enable precise positioning of the probe sampling structure 10, ensuring stable sampling. Additionally, the hygiene testing and sampling mechanism 9 features a self-disinfection function, guaranteeing its cleanliness.

[0041] Example 2

[0042] Based on Example 1, such as Figure 2 , Figure 3 , Figure 5 As shown, the rotary cutting mechanism 2 includes two rotary support seats 21, which are bolted to the front and rear sides of the conveyor frame 1 respectively. The two rotary support seats 21 are symmetrical to each other. A rotating shaft 1 22 and a rotating shaft 23 are connected through and rotatably between the two rotary support seats 21. The rotating shaft 1 22 and the rotating shaft 23 are arranged symmetrically up and down. A rotary wheel 24 is keyed to the center of the rotating shaft 1 22 and the rotating shaft 23. A tool structure 3 is provided on the rotating wheel 24. A gear 25 is keyed to one side of the rotating shaft 1 22 and the rotating shaft 23. A drive gear 26 is provided between the rotating shaft 1 22 and the rotating shaft 23. The gear 25 and the drive gear 26 mesh with each other. A drive motor 27 is provided on one side of the drive gear 26. The drive motor 27 is bolted to the side of the conveyor frame 1. The drive gear 26 is keyed to the output shaft of the drive motor 27. Cranks 28 are bolted to both ends of the rotating shaft 23. A rotary pushing structure 4 is provided on the side of the two rotary support seats 21.

[0043] The tool structure 3 includes several tool holders 31, which are respectively disposed in several nested tool slots 32. The nested tool slots 32 are arranged in a ring on the circumference of the rotary wheel 24. The tool holders 31 are all sleeved on the fixing bolts 33. Both ends of the fixing bolts 33 are threaded through and connected to the rotary wheel 24. A cutting blade 34 is fixedly connected to the tool holder 31. Two buffer sleeves 35 are symmetrically fixedly connected to one side of the cutting blade 34. A crossbar 36 is fixedly connected between the two buffer sleeves 35.

[0044] The rotary pushing structure 4 includes a crossbar 41, with both ends of the crossbar 41 slidably connected to the pushing chute 42, which is located on the conveying platform 1. A right-angle push plate 43 is bolted to the center of the crossbar 41. A push-pull electric telescopic rod 44 is provided above the pushing chute 42 and is bolted to the conveying platform 1. The working end of the push-pull electric telescopic rod 44 is bolted to the crossbar 41. Photoelectric sensors are provided on the push-pull electric telescopic rod 44 and the crank 28.

[0045] The working principle and beneficial effects of the above technical solution are as follows: After the drive motor 27 starts, the output shaft drives the drive gear 26 to rotate. Since the drive gear 26 meshes with two gears 25 at the same time and is an external meshing structure, the rotating shaft 1 22 and the rotating shaft 23 will rotate in opposite directions. The rotating shaft 1 22 and the rotating shaft 23 drive their respective rotary wheels 24 to rotate. The rotation of the rotary wheels 24 drives the knife holder 31 in the nested knife groove 32 to form a relative rotational cutting motion. The cutting blade 34 cuts the wet paper towel. During the cutting process, the horizontal strip 36 is synchronously moved under the action of the spring force in the buffer sleeve 35. The wet paper towel is clamped and cut into two parts. The front part of the wet paper towel is clamped by the horizontal bar 36 on the front cutting blade 34 and enters the conveying and collecting mechanism 5. The rear part of the wet paper towel continues to move forward under the clamping of the horizontal bar 36 on the rear cutting blade 34, waiting for the next cutting blade 34 to cut. The fixing bolt 33 ensures that the blade holder 31 is fixedly installed in the nested blade groove 32 by passing through the blade holder 31 and the rotary wheel 24. The spring elasticity of the buffer sleeve 35 makes the horizontal bar 36 keep the wet paper towel clamped before and after entering the cutting blade 34.

[0046] When the wet paper towels are stacked under the transport of the conveying and collecting mechanism 5, the crank 28 at the outer end of the rotating shaft 23 rotates synchronously with the rotating shaft 23. When the crank 28 passes the push-pull electric telescopic rod 44, the photoelectric sensors on both transmit signals to each other. The push-pull electric telescopic rod 44 pushes the crossbar 41 to slide in the push groove 42, which drives the right-angle push plate 43 to move. When the right-angle push plate 43 moves forward, it pushes out the stacked wet paper towels. After the push-pull electric telescopic rod 44 drives the crossbar 41 and the right-angle push plate 43 to reset, the linkage control of cutting and feeding is realized.

[0047] This invention utilizes a dual-axis counter-rotating cutter structure 3 to create a "cutting" effect. Compared to single-axis cutting, this improves cutting efficiency and stability, reduces slippage or tearing issues associated with single-sided cutting, and ensures that the feeding rhythm and cutting frequency are precisely matched by the crank 28 and the rotating shaft 23. The design of the nested cutter groove 32 and the fixing bolt 33 allows for quick disassembly and replacement of the cutter holder 31 without the need for an overall disassembly mechanism, reducing maintenance costs and downtime. The buffer sleeve 35 absorbs the impact force of mutual collisions through elastic deformation, ensuring stable delivery of wet paper towels.

[0048] Example 3

[0049] Based on Example 1, such as Figure 4 , Figure 6 , Figure 7 As shown, the conveying and collecting mechanism 5 includes four electric rollers 51, which are symmetrically distributed in pairs on both sides of the transverse trough 52. The transverse trough 52 is located on the conveying platform 1. Several driven rollers 53 are arranged horizontally on the right side of each of the four electric rollers 51. The four electric rollers 51 and the several driven rollers 53 are all located on the side wall of the transverse trough 52. The four electric rollers 51 and the several driven rollers 53 are connected by flexible belts 54. A pressing structure 6 is provided above the transverse trough 52, and a collecting mechanism 7 is provided below the transverse trough 52.

[0050] The pressing structure 6 includes two support plates 61, which are symmetrically fixed to the top surface of the conveyor frame 1. A crankshaft 62 is provided between the two support plates 61, with both ends of the crankshaft 62 passing through and rotatably connected to the two support plates 61. A crankshaft motor 63 is bolted to the outer side of one of the support plates 61. One end of the crankshaft 62 is connected to the working end of the crankshaft motor 63. A roller 64 is rotatably connected to the middle section of the crankshaft 62. A semi-circular arc plate 65 is provided below the crankshaft 62. Wheel 64 slides relative to semi-circular arc plate 65. A reciprocating crossbar 66 is fixedly connected to the bottom of the semi-circular arc plate 65. Slide rails 67 are bolted to the inner side walls of the two supporting upright plates 61. The two ends of the reciprocating crossbar 66 are slidably connected in the slide rails 67. A compression elastic element 610 is provided between the reciprocating crossbar 66 and the slide rails 67. A pressing plate 68 is bolted to the lower end of the reciprocating crossbar 66. Pressing rods 69 are fixedly connected to both sides of the reciprocating crossbar 66. The bottom of the pressing rods 69 passes through and is slidably connected to the conveyor frame 1.

[0051] The working principle and beneficial effects of the above technical solution are as follows: The electric roller 51 is driven to rotate by a motor. The working end of the electric roller 51 and several driven rollers 53 are rotatably connected to the side wall of the transverse groove 52. The electric roller 51 drives the driven rollers 53 to rotate synchronously through the flexible belt 54, forming a continuous conveying power. The material is placed between two flexible belts 54. The wet paper towel is conveyed horizontally along the movement of the flexible belt 54. The crankshaft motor 63 synchronously drives the crankshaft 62 to rotate. The roller 64 in the middle section of the crankshaft 62 rolls in the arc-shaped track of the semi-circular arc plate 65. When the wet paper towel reaches the... When the pressing structure 6 is below, the crankshaft 62 rotates, the roller 64 pushes the semi-circular arc plate 65 to drive the reciprocating crossbar 66 to move downward along the slide 67, the compression elastic element 610 stores elastic potential energy, the pressing plate 68 presses the wet paper towel between the flexible belts 54 into the collection mechanism 7, and at the same time the pressing rod 69 presses down on the collection mechanism 7, the crankshaft 62 continues to rotate, after the roller 64 leaves the highest point of the semi-circular arc plate 65, the compression elastic element 610 releases potential energy to push the reciprocating crossbar 66 to reset and move upward, driving the pressing plate 68 and the pressing rod 69 to form a periodic up and down reciprocating motion;

[0052] This invention utilizes a flexible belt 54 to connect the electric roller 51 and the driven roller 53, which can maintain flexible conveying of wet paper towels while enhancing the support for the wet paper towels, preventing sagging or deviation during conveying. The crankshaft 62 is speed-regulated by the crankshaft motor 63, which can precisely control the pressing frequency in conjunction with the conveying speed to achieve fixed-distance pressing, and has high linkage.

[0053] Example 4

[0054] Based on Example 3, such as Figure 8 , Figure 9 , Figure 10 As shown, the collecting mechanism 7 includes a semi-open housing 71, which is bolted to the bottom surface of the conveying platform 1. A reset sleeve 72 is fixedly connected to the bottom of the semi-open housing 71. A reset support rod 73 is slidably connected inside the reset sleeve 72. A compression elastic element 74 is provided between the bottom of the reset support rod 73 and the reset sleeve 72. A support plate 75 is fixedly connected to the top of the reset support rod 73. The support plate 75 slides relative to the semi-open housing 71. Guide grooves 76 are provided on both sides of the semi-open housing 71. The guide groove 76 has a ratchet track 77 and a reset slide 78 on its side wall. The ratchet track 77 and the reset slide 78 are connected to each other at both ends. The bottom of the reset slide 78 is provided with a one-way catch. The ratchet in the ratchet track 77 meshes with one end of the pawl 79. The other end of the pawl 79 is slidably connected in the horizontal slide 710. The horizontal slide 710 is fixedly connected to the side of the support plate 75. A compression elastic element 711 is provided between the pawl 79 and the horizontal slide 710. The left side of the guide groove 76 is provided with a retraction push structure 8.

[0055] The retraction push structure 8 includes a retraction tooth frame 81, which is slidably connected to the side wall of the guide groove 76. A compression elastic element 83 is provided between the retraction tooth frame 81 and the guide groove 76. Several limiting partitions 82 are rotatably connected inside the retraction tooth frame 81. A rotational elastic element is provided between the retraction tooth frame 81 and the limiting partitions 82. The limiting partitions 82 mesh with the pawl 79. The top of the retraction tooth frame 81 abuts against the pressing rod 69.

[0056] The working principle and beneficial effects of the above technical solution are as follows: When the wet paper towel is pressed by the pressing plate 68 and falls into the support plate 75 in the semi-open housing 71, the pressing rod 69 presses the retraction tooth frame 81, causing the retraction tooth frame 81 to slide along the guide groove 76 and squeeze and compress the elastic element 83. At the same time, due to the upward limiting effect of the limiting partition 82 (when the limiting partition 82 rotates in the retraction tooth frame 81, the limiting partition 82 can only rotate downward, and the upward rotation is restricted by the structure of the retraction tooth frame 81), the limiting partition 82 pushes the pawl 79 to move downward one step along the ratchet in the ratchet track 77 and engage with the ratchet in the ratchet track 77. At the same time, the support plate 75 drives the reset support rod 73 to slide along the reset sleeve 72 and squeeze and compress the elastic element 74. After the pressing rod 69 resets, the retraction tooth frame 81... The compression elastic element 83 is used to reset the paper towels upward until it reaches the top. During this process, the pawl 79 will squeeze the limiting partition 82 to make it rotate downward. After the retraction tooth frame 81 is reset, the limiting partition 82 is reset under the action of the rotating elastic element. When the support plate 75 descends to the lowest end, the rotary pushing structure 4 pushes the stacked wet paper towels out of the support plate 75. Then, the pressing structure 6 presses the retraction tooth frame 81 again, pushing the pawl 79 along the ratchet track 77 into the reset slide 78. The pawl 79 slides along the horizontal slide 710 and squeezes the compression elastic element 711. Under the action of the compression elastic element 74, the reset support rod 73 and the support plate 75 are pushed up. After the pawl 79 reaches the top of the reset slide 78, it returns to the top of the ratchet track 77 under the action of the compression elastic element 711 and engages with the limiting partition 82.

[0057] This invention utilizes a support plate 75 to support and collect wet wipes, while simultaneously employing a reset sleeve 72 and a reset support rod 73 to achieve a lifting function. This design allows for continuous stacking of wet wipes, ensuring automatic edge alignment during stacking and improving stacking regularity. Furthermore, the design of the ratchet path 77 and the reset slide 78 ensures that the support plate 75 gradually descends and resets upon reaching the bottom. The design of the retraction tooth frame 81 and the limiting partition 82 prevents direct compression of the wet wipes during stacking, ensuring the saturation of the liquid within the wet wipes.

[0058] Example 5

[0059] Based on Example 1, such as Figure 11 As shown, the external disinfection structure 95 includes a detection base 951, which is located on the conveyor frame 1. Several ultraviolet lamps 952 are installed on both sides of the detection base 951. A detection port 953 is provided inside the detection base 951, which is located below the traveling truss 91. A detection box 954 is bolted inside the detection base 951.

[0060] The probe sampling structure 10 includes a fan-shaped probe box 101, which is bolted to the working end of an electric telescopic rod 94. An electric rotating shaft 102 is provided at the bottom of the fan-shaped probe box 101, and a probe disk 103 is slidably connected to the electric rotating shaft 102. Four liquid aspiration probes 104 are arranged in a ring on the probe disk 103. Several sliding teeth 105 are fixedly connected to the bottom of the probe disk 103. A corrugated baffle 106 is fixedly connected inside the fan-shaped probe box 101. The sliding teeth 105 slide relative to each other along the corrugated baffle 106. Two short baffles 107 are arranged at intervals between the corrugated baffle 106 and the fan-shaped probe box 101. The two short baffles 107 are fixedly connected to the bottom of the fan-shaped probe box 101. A disinfection zone is provided between the two short baffles 107. An infrared emitter 108 is provided between the corrugated baffle 106 and the fan-shaped probe box 101. The infrared emitter 108 passes through and is fixedly connected to the bottom of the fan-shaped probe box 101.

[0061] The working principle and beneficial effects of the above technical solution are as follows: The traveling platform 92 moves on the traveling truss 91 via the lead screw 93 to achieve precise positioning of the probe sampling structure 10 above the detection base 951. After positioning, the electric telescopic rod 94 drives the probe sampling structure 10 to descend vertically, inserting the liquid aspiration probe 104 into the wet paper towel to be tested below the detection port 953. The liquid in the wet paper towel is absorbed by negative pressure. Subsequently, the electric telescopic rod 94 rises, and the traveling platform 92 drives the aspiration probe in the fan-shaped probe box 101 to rise. The liquid probe 104 moves to the detection chamber 954, and then the electric telescopic rod 94 descends again, allowing the liquid probe 104 to enter the detection port of the detection chamber 954 to detect the liquid in the wet wipe. After one liquid probe 104 completes sampling and testing, the working end of the electric rotating shaft 102 rotates in the fan-shaped probe box 101, driving the probe disk 103 to rotate 90° clockwise, so that the sampled liquid probe 104 rotates into the fan-shaped probe box 101, and the disinfected liquid probe 104 rotates out of the fan-shaped probe box. During rotation, the sliding teeth 105 of the box 101 first rise and then fall along the inclined surface of the corrugated partition 106. This ensures that when the aspiration probe 104 enters and exits the fan-shaped probe box 101 and passes through the low partition 107, the probe disk 103 and the aspiration probe 104 remain at a high position, allowing the bottom of the aspiration probe 104 to pass over the low partition 107. After passing over the low partition 107, the probe disk 103 and the aspiration probe 104 gradually descend to a low position, allowing the aspiration probe 104 between the two low partitions 107 to be immersed in the disinfection area. The alcohol disinfectant solution is used for cleaning and disinfection. At the same time, the infrared emitter 108 heats the aspiration probe 104 transferred from the alcohol disinfectant solution in the disinfection area, causing the alcohol disinfectant solution in the aspiration probe 104 to evaporate and perform secondary disinfection. The ultraviolet lamps 952 on both sides of the detection base 951 are automatically turned on before and after sampling to irradiate the detection port 953 area and the outside of the fan-shaped probe box 101, further killing microorganisms in the environment, forming a triple disinfection system of "alcohol immersion + infrared irradiation + ultraviolet irradiation".

[0062] This invention utilizes a combination of alcohol immersion (contact disinfection) and infrared and ultraviolet irradiation (non-contact disinfection) to perform three-dimensional sterilization of the surface, interior, and surrounding space of the liquid absorption probe 104, ensuring zero contamination during the sampling process. Through the 90° intermittent rotation of the electric rotating shaft 102, four samplings can be completed continuously without stopping the machine for disinfection, improving efficiency by more than 300% compared to a single liquid absorption probe 104. The movement trajectory of the traveling truss 91 can be preset by the PLC for precise positioning. At the same time, this design can perform real-time online sampling and detection of wet wipes, promptly identifying contamination status of wet wipes in each production batch.
