Description

Technical Field

[0001] This application relates to the field of wet wipe processing technology, and in particular to a slitting device for a wet wipe production line. Background Technology

[0002] In the production of wet wipes, the slitting of non-woven fabric is one of the steps. During the slitting process, some non-woven fabric is not completely broken after cutting and still maintains a certain connection. However, the existing slitting mechanism lacks an effective separation device, making it difficult to completely separate these incompletely broken non-woven fabrics. This may lead to problems such as non-woven fabric entanglement in subsequent production processes, affecting production efficiency and product quality.

[0003] Meanwhile, the subsequent conveying and stacking of the slit nonwoven fabric are also crucial steps. The connection between the existing slitting mechanism and the conveying device is not smooth enough. When transferring the slit nonwoven fabric from the slitting area to the packaging line, issues such as fabric displacement and wrinkles can easily occur, which is detrimental to subsequent stacking and packaging operations.

[0004] To address the aforementioned issues, a slitting device for a wet wipes production line is now designed. Utility Model Content

[0005] This application provides a slitting device for a wet wipe production line to solve the problem in the related art where some slitting mechanisms do not completely sever the nonwoven fabric after slitting, and still maintain a certain connection.

[0006] Firstly, a slitting device for a wet wipes production line is provided, comprising:

[0007] Conveyor line one and conveyor line two are arranged sequentially;

[0008] The conveyor line is sequentially equipped with a tensioning mechanism, a slitting mechanism, and a partitioning mechanism. The tensioning mechanism is used to tension the conveyed nonwoven fabric, the slitting mechanism is used to slit the nonwoven fabric, and the partitioning mechanism separates the nonwoven fabric that has not been broken after slitting.

[0009] The slitting mechanism includes a mounting frame, a rotating shaft rotatably mounted inside the mounting frame, cutting blades arranged in a ring on the rotating shaft, and a driving component mounted on the mounting frame. The driving component drives the rotating shaft to rotate, thereby cutting the non-woven fabric through the cutting blades.

[0010] The second conveyor line is equipped with a stacking mechanism, which is used to stack the slit nonwoven fabric.

[0011] In some embodiments, the conveyor line includes a frame and a steel belt conveyor mounted on the frame, the steel belt conveyor having a stainless steel conveyor belt for conveying nonwoven fabric.

[0012] In some embodiments, the partition mechanism includes a mounting plate mounted on a frame, two drive rollers rotatably mounted on the mounting plate, a conveyor belt being driven to the outer sides of the two drive rollers, and a second drive member mounted on the mounting plate, which is connected to one of the drive rollers to drive the conveyor belt to rotate.

[0013] The lower surface of the conveyor belt is in contact with the cut non-woven fabric on the stainless steel conveyor belt;

[0014] The rotation direction of the conveyor belt is the same as

[0015] In some embodiments, the second conveyor line includes a second frame, on which two conveyors are symmetrically arranged vertically, and the two conveyors have a stacking channel that is interconnected.

[0016] In some embodiments, the conveyor includes:

[0017] The side panels are set on the second frame;

[0018] Two drive rollers are rotatably mounted at both ends of the two side plates;

[0019] A conveyor belt is connected between the outer sides of the two drive rollers on the same side.

[0020] A drive shaft is coaxially arranged between the two drive rollers at one end;

[0021] A driving component three is provided on one side plate;

[0022] The driving component three is connected to one end of the transmission roller and is used to drive the two conveyor belts two to rotate synchronously.

[0023] There is a gap between the two conveyor belts, and the upper and lower gaps are connected to form a stacking channel.

[0024] In some embodiments, the stacking mechanism includes:

[0025] A bracket is installed above the two side plates above;

[0026] A cylinder mounted on a bracket;

[0027] A pressing plate connected to the cylinder piston rod, the pressing plate being located above the gap;

[0028] An electric push rod is installed on frame two;

[0029] A receiving plate is disposed above the piston rod of the electric push rod, and the receiving plate is located in the middle of the stacking channel.

[0030] In some embodiments, the tensioning mechanism includes two fixed frames disposed opposite each other on the frame, and a guide roller is driven between the two fixed frames;

[0031] Two fixed blocks are slidably arranged on the frame, and two sliding rods are arranged opposite each other between the two fixed blocks. Two abutting blocks are slidably arranged on the outer side of the two sliding rods, and the end of the abutting block near the guide roller is arc-shaped.

[0032] In some embodiments, a guide portion is provided at one end of the steel belt conveyor and the upper conveyor that are in contact with each other, the guide portion being used to guide the slit nonwoven fabric on the steel belt conveyor to the upper conveyor;

[0033] The guiding part includes two fixed seats 1 set above the steel belt conveyor and two fixed seats 2 set on the upper conveyor. A rotating shaft 2 is rotatably connected between the two fixed seats 1 and between the two fixed seats 2. Two guide rollers 2 are arranged opposite each other on the rotating shaft 2. A conveyor belt 3 is drivenly connected to the outer side of the two guide rollers 2 on the same side.

[0034] This application provides a slitting device for a wet wipe production line. Through the cooperation of the slitting mechanism and the partitioning mechanism, while the cutting blade cuts the non-woven fabric, the conveyor belt applies tension to one end of the non-woven fabric, forming a synergistic effect. This action mode can ensure that the non-woven fabric is completely separated after slitting, avoid the problem of non-woven fabric sticking together, and improve production efficiency and product quality.

[0035] The tensioning mechanism keeps the non-woven fabric flat and taut before cutting. Because the non-woven fabric is taut during the cutting process, the cutting blade can apply cutting force evenly, making the cut surface smoother and flatter, reducing the generation of burrs and fluff, and improving the appearance quality and comfort of the wipes.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] This application provides a slitting device for a wet wipe production line, which solves the problem in some existing slitting mechanisms in the related art that, after slitting nonwoven fabric, some nonwoven fabric is not completely broken after cutting and still maintains a certain degree of connection.

[0046] Please see Figures 1-3A slitting device for a wet wipe production line includes: a first conveyor line 1 and a second conveyor line 2 arranged sequentially; the first conveyor line 1 is sequentially equipped with a tensioning mechanism 3, a slitting mechanism 4, and a separating mechanism 5. The tensioning mechanism 3 is used to tension the conveyed non-woven fabric, the slitting mechanism 4 is used to slit the non-woven fabric, and the separating mechanism 5 separates the non-woven fabric that has not been broken after slitting; the slitting mechanism 4 includes a mounting frame 41, a rotating shaft 42 is rotatably mounted inside the mounting frame 41, the rotating shaft 42 is equipped with annularly distributed cutting blades 43, and a driving component 44 is mounted on the mounting frame 41. The driving component 44 drives the rotating shaft 42 to rotate, thereby cutting the non-woven fabric through the cutting blades 43. The driving component 44 includes a drive motor and a reducer. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to one end of the rotating shaft 42. The second conveyor line 2 is equipped with a stacking mechanism 6, which is used to stack the slit non-woven fabric.

[0047] It should be noted that when the non-woven fabric is being cut, the other end of the non-woven fabric is located at the bottom of the conveyor belt 54 of the partition mechanism 5. That is, when the cutting blade 43 cuts the non-woven fabric, the conveyor belt 54 simultaneously applies force to pull one end of the non-woven fabric, so that the cut non-woven fabric can be completely separated.

[0048] Specifically, after the slitting equipment in the wet wipes production line is turned on, the nonwoven fabric enters from the starting end of conveyor line 1, passes through the tensioning mechanism 3, the slitting mechanism 4, and the partitioning mechanism 5 in sequence, and finally arrives at the stacking mechanism 6 on conveyor line 2. The entire conveying process is ensured by conveyor line 1 and conveyor line 2 to ensure that the nonwoven fabric can move smoothly and continuously.

[0049] When the nonwoven fabric enters the conveyor line 1, it first reaches the tensioning mechanism 3. The tensioning mechanism 3 applies appropriate tension to the nonwoven fabric, keeping it flat and taut during the conveying process. This helps the subsequent slitting mechanism 4 to accurately cut the nonwoven fabric and avoids problems such as inaccurate cutting dimensions or uneven cutting surfaces caused by the loosening of the nonwoven fabric.

[0050] The nonwoven fabric continues to move forward after being tensioned and enters the slitting mechanism 4. The drive motor in the drive unit 44 of the slitting mechanism 4 starts, and its output shaft transmits power to the reducer. The reducer adjusts the speed of the drive motor and then outputs power to the rotating shaft 42, causing the rotating shaft 42 to rotate at a set speed. When the rotating shaft 42 rotates, the cutting blade 43 also rotates at high speed. During the conveying process, the nonwoven fabric passes through the rotating cutting blade 43 and is cut into the required width size.

[0051] At the same time, while the cutting blade 43 is cutting the non-woven fabric, the other end of the non-woven fabric is located at the bottom of the conveyor belt 54 of the partition mechanism 5. The conveyor belt 54 runs at a certain speed and applies a pulling force to one end of the non-woven fabric. This pulling force works in conjunction with the cutting force of the cutting blade 43 to completely separate the cut non-woven fabric into independent small segments of non-woven fabric.

[0052] After separation, the small segments of non-woven fabric enter the second conveyor line 2 through the end of conveyor line 1, and are then conveyed to the stacking mechanism 6. The stacking mechanism 6 stacks the small segments of non-woven fabric layer by layer to form a neat stack of wet wipes, which facilitates the subsequent packaging process.

[0053] The tensioning mechanism 3 ensures that the non-woven fabric remains flat and taut before cutting. Because the non-woven fabric is in a taut state during the cutting process, the cutting blade 43 can apply cutting force evenly, making the cut surface smoother and flatter, reducing the generation of burrs and fluff, and improving the appearance quality and comfort of the wet wipes.

[0054] With the cooperation of the slitting mechanism 4 and the partitioning mechanism 5, while the cutting blade 43 cuts the non-woven fabric, the conveyor belt 54 applies tension to one end of the non-woven fabric, forming a synergistic effect. This action mode can ensure that the non-woven fabric is completely separated after slitting, avoid the problem of non-woven fabrics sticking together, and improve production efficiency and product quality.

[0055] The rotational speed of the shaft 42 is precisely controlled by the drive component 44, which in turn controls the cutting speed of the cutting blade 43, ensuring that the non-woven fabric can be cut into small segments of precise size to meet the specifications of wet wipe production. This is existing technology and will not be described in detail here.

[0056] like Figure 1 and Figure 2 As shown, the conveyor line 1 in this embodiment includes a frame 11 and a steel belt conveyor 12 mounted on the frame 11. The steel belt conveyor 12 has a stainless steel conveyor belt 121 for conveying nonwoven fabric.

[0057] After conveyor line 1 is started, the steel belt conveyor 12 begins to operate under the drive of the power unit, transmitting power to the drive roller of the stainless steel conveyor belt 121. The drive roller drives the stainless steel conveyor belt 121 to perform continuous cyclical motion. This is existing technology and will not be described in detail here.

[0058] The non-woven fabric is placed at the starting end of the stainless steel conveyor belt 121. As the conveyor belt moves, the non-woven fabric is smoothly conveyed forward, passing through the tensioning mechanism 3, the slitting mechanism 4 and the partitioning mechanism 5 in sequence to complete the corresponding processing steps.

[0059] The frame 11 provides a stable support frame for the entire conveyor line 1, which can bear the weight of the steel belt conveyor 12 and the non-woven fabric, ensuring that the conveyor line can transport smoothly during operation.

[0060] Stainless steel conveyor belt 121 has high strength and hardness, can withstand large tensile and frictional forces, and is not easily deformed or damaged. At the same time, the smooth surface of stainless steel provides moderate friction with the non-woven fabric, ensuring that the non-woven fabric does not slip during conveying while avoiding damage to the non-woven fabric due to excessive friction.

[0061] In the wet wipe production environment, the conveyor belt will come into contact with humidifying liquids and other substances. The stainless steel conveyor belt 121 has good corrosion resistance and can resist the erosion of these substances. It is not easy to rust and corrode, thus extending the service life of the conveyor belt.

[0062] like Figure 2 and Figure 6 As shown, in one embodiment, the partition mechanism 5 includes a mounting plate 51 mounted on a frame 11. Two drive rollers 52 are rotatably mounted on the mounting plate 51, and a conveyor belt 54 is driven to the outer sides of the two drive rollers 52. A second drive member 53 is mounted on the mounting plate 51, connected to one of the drive rollers 52 to drive the conveyor belt 54 to rotate. The second drive member 53 includes a drive motor and a reducer. The output shaft of the drive motor is connected to the input shaft of the reducer, and the input shaft of the reducer is connected to one end of any of the drive rollers 52. The lower surface of the conveyor belt 54 contacts the cut non-woven fabric on the stainless steel conveyor belt 121; the rotation direction of the conveyor belt 54 is opposite to the conveying direction of the stainless steel conveyor belt 121.

[0063] When the equipment is started, the drive motor in drive component 53 starts to run, and its output shaft transmits power to the reducer. The reducer adjusts the speed of the drive motor, reduces the speed and increases the torque, and then outputs the power to the connected drive roller 52.

[0064] The powered drive roller 52 begins to rotate. Since the two drive rollers 52 are connected to the conveyor belt 54 on their outer sides and the conveyor belt 54 has a certain tension, the other drive roller 52 will also rotate, thereby causing the conveyor belt 54 to rotate in a circular motion.

[0065] The nonwoven fabric being cut rests on the stainless steel conveyor belt 121. As the conveyor belt 54 rotates, its lower surface contacts one end of the nonwoven fabric being cut. Since the rotation direction of the conveyor belt 54 is opposite to the conveying direction of the stainless steel conveyor belt 121, the conveyor belt 54 applies a tension force to the nonwoven fabric in the same direction as the conveying direction. Under this tension force, any nonwoven fabric that was not completely separated after cutting is completely separated.

[0066] Specifically, when the stainless steel conveyor belt 121 rotates clockwise to transport the non-woven fabric, the conveyor belt 54 rotates counterclockwise, so that the tension applied to the non-woven fabric is in the same direction as the transport of the stainless steel conveyor belt 121.

[0067] The conveyor belt 54 rotates in the opposite direction to the conveying direction of the stainless steel conveyor belt 121, which can generate a strong reverse tension to ensure that the slit non-woven fabric can be separated quickly and thoroughly.

[0068] The transmission system consisting of two drive rollers 52 and a conveyor belt 54 can achieve continuous cyclic motion, enabling continuous slitting operation on the cut nonwoven fabric.

[0069] like Figure 1 and Figure 4 As shown in this embodiment, the second conveyor line 2 includes a second frame 21, and the second frame 21 has two conveyors 22 symmetrically arranged vertically, with a stacking channel 23 connecting the two conveyors 22.

[0070] Conveyor line 2 is mainly used for the stacking of non-woven fabrics in the wet wipes production process. Through two symmetrically arranged conveyors 22 and the stacking channel 23 connecting them, the non-woven fabrics can be accurately stacked during the conveying process, providing the required material form for the packaging process.

[0071] When conveyor line 2 is started, the upper and lower conveyors 22 start operating simultaneously. The upper conveyor 22 transports the upper nonwoven fabric forward. When the nonwoven fabric reaches the stacking channel 23, the stacking mechanism 6 stacks the nonwoven fabric. Multiple stackings are performed as needed. The stacked nonwoven fabric sheets are then fed onto the lower conveyor 22 and continue to be transported forward to complete the stacking process.

[0072] like Figure 2 and Figure 4 As shown, specifically, in one embodiment, the conveyor 22 includes: side plates 221 disposed opposite to each other on the frame 21; two drive rollers 222 rotatably disposed at both ends of the two side plates 221; a conveyor belt 223 drivingly connected between the outer sides of the two drive rollers 222 on the same side; a drive shaft 224 coaxially disposed between the two drive rollers 222 at one end; a drive component 225 disposed on one side of the side plate 221; the drive component 225 is connected to one end of the drive rollers 222 and is used to drive the two conveyor belts 223 to rotate synchronously; there is a gap between the two conveyor belts 223, and the upper and lower gaps are connected to form a stacking channel 23. The drive component 225 includes a drive motor and a reducer, the output shaft of the drive motor is connected to the input shaft of the reducer, both ends of the drive shaft 224 extend outside the side plate 221, and the output shaft of the reducer is connected to either end of the drive shaft 224.

[0073] Side plates 221 are mounted opposite each other on frame 21, serving as the basic support structure for conveyor 22 and providing installation positions for other components. Meanwhile, non-woven fabric is positioned between the two side plates 221 to limit the movement of the conveyed non-woven fabric.

[0074] When the drive motor in drive component 225 starts, its output shaft drives the input shaft of the reducer to rotate. After the reducer reduces speed and increases torque, it transmits power to the transmission shaft 224 through the output shaft. Since the transmission shaft 224 is coaxially connected to the two transmission rollers 222 on the same side, the transmission rollers 222 will rotate together with the transmission shaft 224. The rotation of the transmission rollers 222 drives the conveyor belt 223 to rotate in a cycle. The two conveyor belts 223 rotate synchronously under the action of drive component 225.

[0075] like Figure 2 and Figure 5 As shown, in one embodiment, the stacking mechanism 6 includes: a bracket 61 disposed above the two upper side plates 221; a cylinder 62 disposed on the bracket 61; a pressing plate 63 connected to the piston rod of the cylinder 62, the pressing plate 63 being located above the gap; the pressing plate 63 includes a fixing plate disposed at the bottom end of the piston rod of the cylinder 62, and two pressing blocks disposed opposite each other at the bottom end of the fixing plate, the pressing blocks being located directly above the center of the gap. An electric push rod 64 is disposed on the second frame 21; a receiving plate 65 is disposed above the piston rod of the electric push rod 64, the receiving plate 65 being located in the middle of the stacking channel 23. Four rectangular guide rods are disposed at the bottom of the receiving plate 65, and a second fixing plate is disposed on the outer side of the electric push rod 64, the second fixing plate having insertion holes adapted to the guide rods, the guide rods slidingly engaging with the corresponding insertion holes.

[0076] The pressing block is located directly above the center of the gap, allowing the pressing disc 63 to apply pressure evenly to the nonwoven fabric, ensuring that the nonwoven fabric does not shift during the pressing process and improving the accuracy of stacking.

[0077] The electric push rod 64 is mounted on the frame 21. The extension and retraction of its piston rod can drive the receiving plate 65 to move up and down. The electric push rod 64 can control the position of the receiving plate 65 to realize the layered stacking and conveying of non-woven fabric. During the stacking process, the piston rod of the electric push rod 64 is in the extended state, so that the receiving plate 65 is located below the two upper conveyor belts 223. When the non-woven fabric is stacked in multiple layers, the electric push rod 64 drives the receiving plate 65 to descend, so that the stacked non-woven fabric comes into contact with the lower conveyor belt 223 for conveying.

[0078] The receiving tray 65 is positioned above the piston rod of the electric push rod 64 and in the middle of the stacking channel 23. It serves as a support platform for non-woven fabric stacking and can receive non-woven fabric pressed down from the upper conveyor belt 223. The bottom of the receiving tray 65 is equipped with four rectangular guide rods that slide in conjunction with corresponding insertion holes to ensure the stability of the receiving tray 65 during its up-and-down movement, preventing the receiving tray 65 from shaking or tilting, thereby ensuring that the non-woven fabric can be stacked neatly.

[0079] In actual production, the piston rod of the electric push rod 64 is in the extended state, and the receiving plate 65 is located below the two upper conveyor belts 223, ready to receive the non-woven fabric. The piston rod of the cylinder 62 extends, driving the pressing plate 63 to move downward, pressing the cut non-woven fabric on the upper conveyor belt 223 onto the receiving plate 65. Since the pressing block of the pressing plate 63 is located directly above the center of the gap, it can ensure that the non-woven fabric falls accurately onto the receiving plate 65.

[0080] After repeated pressing, the nonwoven fabric is stacked in multiple layers on the receiving tray 65. During this process, the electric push rod 64 keeps the piston rod extended, and the receiving tray 65 remains in the same position, continuously receiving the pressed nonwoven fabric. When the nonwoven fabric is stacked to the set number of layers, the piston rod of the electric push rod 64 retracts, causing the receiving tray 65 to descend. At this time, the stacked nonwoven fabric comes into contact with the lower conveyor belt 223, which transports the stacked nonwoven fabric out. After the receiving tray 65 transports the nonwoven fabric out, the piston rod of the electric push rod 64 extends again, causing the receiving tray 65 to rise to the initial position. The above actions are repeated to continuously stack the nonwoven fabric.

[0081] The pressing block of the pressing plate 63 is located directly above the center of the gap, which can accurately press the non-woven fabric into the designated position of the receiving plate 65, avoiding the non-woven fabric from shifting or misaligning during the stacking process. At the same time, the receiving plate 65 ensures its stability during the up and down movement through the sliding cooperation between the guide rod and the fixing plate 2, further improving the accuracy of non-woven fabric stacking.

[0082] According to actual production needs, the number of nonwoven fabric stacking layers, stacking height and conveying speed can be adjusted by adjusting parameters such as the pressing force of cylinder 62, the extension stroke and speed of electric push rod 64. This is existing technology and will not be described in detail here.

[0083] like Figure 1 and Figure 2As shown, in one embodiment, the tensioning mechanism 3 includes two fixed frames 31 disposed opposite to each other on the frame 11, and a guide roller 32 is connected between the two fixed frames 31; two fixed blocks 33 are slidably disposed opposite to each other on the frame 11, two sliding rods 34 are disposed opposite to each other between the two fixed blocks 33, and two abutting blocks 35 are slidably disposed on the outer side of the two sliding rods 34, and the end of the abutting block 35 near the guide roller 32 is arc-shaped.

[0084] When the tension of the nonwoven fabric needs to be adjusted, the abutment block 35 is moved to the appropriate position by pushing the abutment block 35 to slide on the slide bar 34.

[0085] Subsequently, the fixed block 33 is pushed to slide on the frame 11, so that when the fixed block 33, the slide bar 34 and the abutment block 35 move toward the guide roller 32, their arc-shaped ends will gradually increase the pressure on the nonwoven fabric passing over the guide roller 32, so that the nonwoven fabric is subjected to greater tension, thereby achieving tension; conversely, when the abutment block 35 moves away from the guide roller 32, the pressure on the nonwoven fabric decreases, and the tension of the nonwoven fabric will also decrease accordingly.

[0086] like Figure 2 and Figure 4 As shown, in another embodiment, a guide part 7 is provided at one end of the steel belt conveyor 12 and the upper conveyor 22 that are in contact with each other. The guide part 7 is used to guide the nonwoven fabric cut on the steel belt conveyor 12 onto the upper conveyor 22. The guide part 7 includes two fixed seats 71 arranged above the steel belt conveyor 12 and two fixed seats 72 arranged on the upper conveyor 22. A rotating shaft 73 is rotatably connected between the two fixed seats 71 and between the two fixed seats 72. Two guide rollers 74 are arranged opposite each other on the upper part of the rotating shaft 73. A conveyor belt 75 is drivenly connected to the outer side of the two guide rollers 74 on the same side. The bottom of the conveyor belt 75 is in contact with the nonwoven fabric. A drive motor is provided on one fixed seat 71, and the output shaft of the drive motor is connected to one end of the rotating shaft 73.

[0087] When the drive motor starts, its output shaft drives the rotating shaft 73 to rotate. The rotation of the rotating shaft 73 causes the guide roller 74 to rotate accordingly. The guide roller 74 then drives the conveyor belt 75 to circulate. Since the bottom of the conveyor belt 75 is in contact with the non-woven fabric, the non-woven fabric is smoothly guided to the conveyor 22 above under the action of the friction of the conveyor belt 75, thus completing the transfer of the non-woven fabric between different conveying devices.

[0088] The conveyor belts on both sides of the nonwoven fabric come into contact with the two sides of the nonwoven fabric. Through continuous friction, the nonwoven fabric is guided, avoiding shaking, deviation or jamming during the transfer process, thus ensuring the smoothness of the nonwoven fabric conveying.

[0089] The guide unit 7 is equipped with an independent drive motor, and its operation is not affected by the steel belt conveyor 12 and the overhead conveyor 22.

[0090] Furthermore, the independent power system can control the movement speed and force of the conveyor belt according to the conveying speed and load of the nonwoven fabric, thereby improving the accuracy and reliability of nonwoven fabric guidance.
