Description

Technical Field

[0001] This utility model relates to the technical field of wet wipe production equipment, and in particular to a horizontally feeding wet wipe machine. Background Technology

[0002] A wet wipe machine is an automated device that continuously produces single wet wipes from rolls of non-woven fabric through processes such as unwinding, folding, adding liquid, and cutting. In existing technologies, horizontally moving wet wipe machines typically arrange functional mechanisms sequentially along the conveying direction, but they suffer from the following shortcomings: 1. Conventional folding mechanisms often use horizontally arranged folding plates or paper folding rods for reciprocating paper insertion and folding. During folding, the wet wipes are prone to slippage or shifting. Furthermore, the installation structure of the folding plates occupies a large amount of horizontal space, which is not conducive to a compact layout of the equipment. At the same time, the wet wipes lack an effective flattening and tightening structure when entering the folding mechanism, resulting in the wet wipes being in a loose state during folding, which easily leads to uneven folding, skewed creases, and other problems, affecting the folding quality. 2. During the liquid spraying and conveying process, wet wipes are generally equipped with only a single set of traction rollers. After passing through the water spraying mechanism, the wet wipes enter the cutting process, lacking a stable clamping structure for the wet wipes after liquid addition and a structure for handling excess liquid. This results in uneven moisture content of the wet wipes and a decrease in cutting accuracy during cutting. 3. The traction mechanism and output mechanism are often driven independently, requiring multiple sets of motors and control systems to coordinate. This not only increases the equipment manufacturing cost but also makes it difficult to accurately guarantee synchronization, easily causing the wet wipes to accumulate or be pulled at the process transition points. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a horizontally moving wet wipe machine with a compact structure, reasonable design, precise folding, stable conveying, and high transmission synchronization.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a transversely moving wet wipe machine, including a roll unwinding frame, a turning mechanism, a folding mechanism, a water spraying mechanism, a cutting mechanism and an output mechanism arranged sequentially along the wet wipe conveying direction. A front traction component is provided between the turning mechanism and the folding mechanism. A set of rear traction components is provided on both the front and rear sides of the water spraying mechanism. The two sets of rear traction components are synchronously driven by a driving component. The folding mechanism includes a folding frame and several sets of folding components arranged on the folding frame. Each set of folding components includes two folding base plates arranged vertically opposite each other. Two folding plates are vertically arranged between the two folding base plates, and a folding groove for the wet wipe to pass through is formed between the two folding plates.

[0005] Preferably, the front traction assembly includes a front traction frame, on which a front traction roller and a front drive assembly for driving the front traction roller to rotate are vertically arranged, and the front traction frame is also provided with a front traction auxiliary roller adapted to the front traction roller.

[0006] Preferably, the folding assembly is slidably mounted on the folding frame via the first guide rail, and the folding plate is slidably mounted between the folding substrates via the second guide rail. The cross-section of the folding groove is composed of multiple V-shaped grooves connected in sequence, and the V-shaped angle of the folding groove of each folding assembly gradually decreases along the wet wipe conveying direction.

[0007] Preferably, each rear traction assembly includes two sets of traction units arranged symmetrically above and below each other, forming a traction channel between the two sets of traction units for the wet wipes to pass through. The traction unit includes a driving roller, multiple driven rollers, and a traction belt wound around the driving roller and the driven rollers.

[0008] Preferably, the drive assembly includes a first drive motor, the output end of which is driven and connected to one of the drive rollers via a first synchronous belt, and the drive rollers of the rear traction assembly are connected to each other via a second synchronous belt.

[0009] Preferably, the output mechanism includes two sets of oppositely arranged discharge conveying components, forming a discharge channel between the two sets of discharge conveying components. Both sets of discharge conveying components include discharge rollers, and the two discharge rollers are connected by a synchronous pulley drive. One of the discharge rollers is connected to the drive roller of the traction unit by a third synchronous belt drive.

[0010] Preferably, the water spraying mechanism includes a water tank and a water trough located at the upper port of the water tank. The water trough is provided with main water spraying pipes on both sides of the wet wipe conveying track. Each main water spraying pipe is vertically connected to several branch water spraying pipes. The upper port of the water tank extends from the output end of the rear traction component at the front of the water spraying mechanism to the input end of the output mechanism.

[0011] The beneficial effects of this utility model are:

[0012] 1. By vertically setting the folding plate between the upper and lower folding base plates and forming a folding groove with multiple V-shaped grooves, the wet wipes are continuously and progressively folded along the vertical channel, which effectively reduces the lateral space occupied by the folding mechanism. The V-shaped angle of the folding groove gradually decreases along the conveying direction, so that the wet wipes are folded from sparse to dense, avoiding the problems of crease skewing and paper slippage caused by a large angle fold in one go. The folding is highly neat. A front traction component is added to the front of the folding mechanism to clamp and flatten the wet wipes before they enter the folding process, so that the wet wipes remain taut during the folding process, further improving the accuracy and efficiency of folding.

[0013] 2. Rear traction components are installed on both sides of the water spraying mechanism. Before entering the water spraying area, the wet wipes are stably clamped by the front rear traction components. After adding liquid, they immediately enter the traction channel of the rear rear traction components. The multiple driven rollers of the rear rear traction components guide and squeeze the wet wipes after adding liquid, which can naturally drain excess liquid, making the moisture content of the wet wipes more uniform and controllable before cutting. At the same time, the upper port of the water tank extends to cover the entire conveying path from the liquid adding area to the output mechanism, so that the secondary dripping after adding liquid and the liquid drained in the later section can fall directly into the water tank for recycling, effectively preventing liquid splashing and contaminating the machine, and ensuring the uniformity of the moisture content of the wet wipes before cutting.

[0014] 3. The active rollers of the two sets of rear traction components are linked by the second synchronous belt, and the output roller of the output mechanism is connected to the active roller of the traction unit through the third synchronous belt. This allows the traction before and after water spraying and the output after cutting to be driven by the same drive motor, reducing the number of independent motors and sensors, lowering manufacturing costs, and ensuring the precise synchronization of the entire line's conveying speed.

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0022] like Figures 1 to 5 The illustrated horizontally feeding wet wipe machine has a frame on which, along the conveying direction of the nonwoven fabric roll, are arranged in sequence an unwinding frame 1, a turning mechanism 2, a front traction assembly 9, a folding mechanism 3, a water spraying mechanism 4, a cutting mechanism 5, and an output mechanism 6. A set of rear traction assemblies 7 are provided on both the front and rear sides of the water spraying mechanism 4.

[0023] The unwinding frame 1 has horizontally mounted unwinding rollers for carrying the nonwoven fabric rolls. The turning mechanism 2 includes several horizontally arranged first guide rollers, inclined turning rollers, and several vertically arranged second guide rollers, which are used to guide the unwound nonwoven fabric from the horizontal direction to the vertical direction so that it can enter the folding mechanism 3.

[0024] The front traction assembly 9 is located between the steering mechanism 2 and the folding mechanism 3. The front traction assembly 9 includes a front traction frame 91, on which a front traction roller 92 and a front drive assembly 938 for driving the front traction roller 92 are vertically mounted. The front drive assembly 938 can be powered by an independent motor or by linkage with a downstream transmission mechanism. The front traction frame 91 also has a front traction auxiliary roller 94 adapted to the front traction roller 92. The upper and lower ends of the front traction auxiliary roller 94 are slidably mounted on the front traction frame 91 via adjusting components. The adjusting components include a slider and a lead screw structure, with the slider rotating relative to the end of the front traction auxiliary roller 94. The connection is made so that the lead screw is rotatably mounted on the front traction frame 91. The lead screw passes through the slider and is threadedly engaged with the slider. By turning the lead screw, the slider can be driven to move along the front traction frame 91, thereby precisely adjusting the gap between the front traction auxiliary roller 94 and the front traction roller 92 to accommodate wet wipe materials of different thicknesses. Through the cooperation of the front traction roller 92 and the front traction auxiliary roller 94 and the cooperation of the rear traction component 7, the wet wipe is effectively flattened and tightened before entering the folding mechanism 3, ensuring that the two ends of the wet wipe are in a stable taut state during folding, thus providing a guarantee for subsequent precise folding.

[0025] The folding mechanism 3 includes a folding frame 31 with a first guide rail 35. Several sets of folding components are slidably mounted on the folding frame 31 via the first guide rail 35, and the spacing between each set of folding components can be adjusted according to production needs. Each set of folding components includes two folding base plates 32 arranged vertically opposite each other. Two folding plates 33 are mounted between the two folding base plates 32 via a second guide rail 36, which are located on the same vertical plane. That is, the inner walls of the two folding plates 33 are parallel to each other and located in the same plane, with a gap between the two plates to form a folding groove 34 for the wet wipe to pass through. The cross-section of the folding groove 34 is composed of multiple V-shaped grooves connected in sequence. The bending direction of the V-shaped grooves causes the wet wipe to be gradually squeezed and folded along the conveying direction. Along the conveying direction of the wet wipe, the V-shaped angle of the folding groove 34 in each set of folding components gradually decreases from about 135° to about 30° to 45°, realizing a progressive folding shape from sparse to dense. Those skilled in the art can adjust the number of folding components and the specific value of the V-shaped angle according to the material of the wet wipes and the required number of folding layers. Such adjustments are within the range that can be determined by conventional experimental methods and do not require creative labor.

[0026] The water spraying mechanism 4 is located behind the folding mechanism 3 and includes a water tank 41 and a water trough 42 located at the upper port of the water tank 41. The upper port of the water tank 41 is a rectangular container opening, whose length extends from the output end of the rear traction assembly 7 at the front of the water spraying mechanism 4 to the input end of the output mechanism 6. The width of the water trough 42 matches the width of the wet wipe conveying track. A main water spraying pipe 43 is provided on each side of the track corresponding to the water trough 42. Several branch water spraying pipes 44 are vertically connected along the length of each main water spraying pipe 43, and the nozzles of the branch water spraying pipes 44 face the wet wipes. A liquid pump (not shown in the figure) pumps the impurity in the water tank 41 to the main water spraying pipe 43, and sprays it evenly onto the wet wipes that pass through the branch water spraying pipes 44.

[0027] Each rear traction assembly 7 includes two traction units arranged symmetrically at the top and bottom, forming a traction channel for the wet wipes to pass through. Each traction unit includes a drive roller 71, multiple driven rollers 72, and a traction belt 73 wound around the drive roller 71 and the driven rollers 72. The surface of the traction belt 73 is textured to increase friction, ensuring stable clamping and conveying of the wet wipes.

[0028] The drive assembly 8 includes a first drive motor 81, the output of which is connected to one of the drive rollers 71 of one of the rear traction assemblies 7 via a first synchronous belt 82. The drive rollers 71 of the two rear traction assemblies 7 are connected by a second synchronous belt 83, enabling the two rear traction assemblies 7 to operate synchronously. This structure ensures that the wet wipes are stably pulled before and after adding liquid, and the rear traction assembly 7, located behind the water spraying mechanism 4, gently presses and drains the wet wipes while pulling them. Excess liquid squeezed out and liquid that drips naturally from the surface of the wet wipes fall into the rear half of the recovery area at the upper port of the water tank 41 before entering the cutting mechanism 5, and flow back to the water tank 41.

[0029] The cutting mechanism 5 includes a cutting roller, a blade support roller, and a second motor that drives them to rotate. The cutting roller is equipped with a spiral or straight cutting blade for cutting the continuously folded wet wipes into single pieces.

[0030] The output mechanism 6 includes two sets of discharge conveying components arranged vertically opposite each other, forming a discharge channel between them. Each set of discharge conveying components includes a discharge roller 61, a discharge guide roller, and a discharge belt. The lower discharge conveying component also has a discharge auxiliary roller below its output end. The discharge belt of this component is wound around the auxiliary roller for easy connection to subsequent workstations. The discharge rollers 61 of the two sets of discharge conveying components are connected by a synchronous pulley 62. One of the discharge rollers 61 is connected to the drive roller 71 of the second rear traction component 7 via a third synchronous belt 63, ensuring that the cut single-piece wet wipes are output at a rate synchronized with the traction speed, preventing stacking or breakage at the discharge port.

[0031] The working process of this embodiment is as follows: The non-woven fabric roll is unwound by the unwinding roller and guided to the vertical direction by the turning mechanism 2; then it enters the front traction assembly 9, where the non-woven fabric is clamped and conveyed by the front traction roller 92 and the front traction auxiliary roller 94, and enters the folding mechanism in a stable tension state; the non-woven fabric passes through the folding grooves 34 of each folding assembly in sequence, and is gradually folded under the guidance of the V-shaped channel; the folded non-woven fabric strip is clamped by the first rear traction assembly 7 and sent into the water tank 42 area of ​​the water spraying mechanism 4, where liquid is evenly added through the upper and lower water spraying branch pipes 44; the wet wipe strip after adding liquid enters the second rear traction assembly 7, where excess liquid is squeezed out while being pulled and conveyed, and the dripping liquid and drained water are collected by the water tank 41 below; then it enters the cutting mechanism 5, where the cutting roller and the blade pillow roller cut it into single wet wipes of a specified length; finally, the output mechanism 6 sends the single wet wipes out to the next station (such as the stacking or packaging station).
