Description

Technical Field

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

[0002] As a convenient cleaning product, wet wipes are widely used in daily life and medical care. Their production process usually includes steps such as unwinding, folding, impregnation, slitting, and rolling. Rolling is the last key process in wet wipe production, and its quality directly affects the uniformity of the product and the user experience.

[0003] Existing wet wipe rolling equipment typically uses belts or rollers with pressure plates for initial winding, followed by final tightening and shaping via other mechanisms or spatial arrangements. However, in the initial winding stage, the wet wipe sheet becomes heavier and softer due to the liquid content, making it difficult to feed stably into the winding station. This can lead to slippage, misalignment, or failure to form an initial bend, resulting in failed rolling or a loose, loose finished product. Furthermore, existing rolling and shaping mechanisms are poorly adaptable to wet wipe sheets of varying lengths, thicknesses, and moisture levels. Adjusting the rolling pressure and contact friction is inconvenient, affecting product consistency and production efficiency. In addition, the connection between wet wipe transport, cutting, and rolling in existing equipment is often not smooth enough, resulting in inaccurate action timing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a wet wipe rapid roll forming machine that has accurate and reliable roll initiation and stable and efficient roll process.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a wet wipe rapid rolling forming machine, including a main frame and a rolling mechanism disposed thereon. The rolling mechanism includes a third rolling roller, a lower rolling plate, a rolling toothed rack and a rolling belt. The third rolling roller is disposed below the rolling belt. A first discharge roller for tensioning the rolling belt is provided in the rolling belt corresponding to the third rolling roller. The lower rolling plate is inclinedly disposed below the rolling belt. The rolling toothed rack is disposed between the third rolling roller and the lower rolling plate. The tooth grooves on the surface of the rolling toothed rack are conical. An insert plate is movably disposed on one side of the input end of the third rolling roller and the rolling belt to push the wet wipe from between the third rolling roller and the rolling belt into the tooth grooves of the rolling toothed rack.

[0006] Preferably, the rolling mechanism further includes a first rolling roller and a second rolling roller arranged in a triangle with the first discharge roller. The rolling belt is sleeved on the first discharge roller, the first rolling roller, and the second rolling roller. The rolling belt includes a conveying section between the first discharge roller and the first rolling roller and a rolling section between the first discharge roller and the second rolling roller. The lower rolling plate and the rolling toothed rack are arranged below the rolling section.

[0007] Preferably, the rolling mechanism further includes a second discharge roller and a third discharge roller, and the second discharge roller and the third discharge roller are fitted with a conveyor belt adapted to the conveying section of the rolling belt, and the rolling belt and the conveyor belt form a conveying channel at the entrance of the rolling mechanism.

[0008] Preferably, a rotating frame is rotatably provided on the inner side of the winding belt, and a winding pressure roller is retractably provided on the rotating frame by bolts. The winding pressure roller is correspondingly arranged with the winding rack and abuts against the inner side of the winding belt.

[0009] Preferably, a swing arm is rotatably provided below the conveying channel, and an insert plate is provided at the movable end of the swing arm. A connecting rod is hinged on the swing arm, and an eccentric disk is connected to the movable end of the connecting rod to drive the swing arm to swing.

[0010] Preferably, the main frame is provided with an unwinding mechanism, a folding mechanism, a traction mechanism, a wetting mechanism for wetting the nonwoven fabric, and a cutting mechanism for cutting the nonwoven fabric in sequence along the working direction.

[0013] The beneficial effects of this utility model are:

[0014] 1.

Detailed Implementation

[0023] 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

[0024] like Figures 1 to 4The illustrated wet wipe rapid roll forming machine includes a main frame 1, which serves as the supporting skeleton of the entire equipment. The main frame 1 is primarily equipped with a roll forming mechanism 2. To achieve a complete wet wipe production line, along the working direction (i.e., the direction of travel of the non-woven fabric and wet wipes), a roll unwinding mechanism 3, a folding mechanism 4, a traction mechanism 5, a wetting mechanism 6, and a cutting mechanism 7 are sequentially arranged. The inlet of the roll forming mechanism 2 is connected to the outlet of the cutting mechanism 7.

[0025] The winding mechanism 2 includes a first discharge roller 201, a first winding roller 202, a second winding roller 203, a third winding roller 204, a lower winding plate 205, a winding rack 206, a second discharge roller 210, and a third discharge roller 211. The first discharge roller 201, the first winding roller 202, and the second winding roller 203 are arranged in a triangle to support and tension a winding belt 207 with a triangular structure. The winding belt 207 includes a conveying section 208 located between the first discharge roller 201 and the first winding roller 202, and a section connected to and positioned above the conveying section 208. The first discharge roller 201 and the second twisting roller 203 are connected by a twisting section 209; the second discharge roller 210 and the third discharge roller 211 are fitted with a conveyor belt 212 that is compatible with the conveying section 208 of the twisting belt 207. The twisting belt 207 and the conveyor belt 212 are closely fitted with the conveying section 208 of the twisting belt 207. The two form a conveying channel 213 at the entrance of the twisting mechanism 2, which clamps and conveys the wet wipe sheet. The conveying channel 213 is directly opposite to and located below the exit of the cutting mechanism 7, and is used to receive the cut wet wipe sheet.

[0026] The third rolling roller 204 is positioned below the first discharge roller 201. The lower rolling plate 205 is inclinedly positioned below the rolling section 209 of the rolling belt 207, forming a gradually widening wedge-shaped rolling space between itself and the rolling section 209. The rolling toothed rack 206 is positioned between the starting end of the third rolling roller 204 and the lower rolling plate 205. The side of the rolling toothed rack 206 close to the third rolling roller 204 abuts against the third rolling roller 204 to effectively transfer the wet wipe to the rolling toothed rack 206. The grooves 214 on the surface of the rolling toothed rack are conical. These grooves 214 are used to "bite" the wet wipe in the initial stage of rolling, assisting it in forming the initial winding.

[0027] To achieve precise guidance and initial bending of the wet wipe sheet before it enters the rolling process, a swing arm 215 is rotatably provided below the conveying channel 213. The movable end of the swing arm 215 is provided with an insert plate 216. Driven by the swing arm 215, the insert plate 216 can swing back and forth within one working cycle and precisely bend the lower part of the wet wipe slightly above the upper part and insert it into the narrow gap between the third rolling roller 204 and the conveying section 208 of the rolling belt 207 until it abuts against the tooth groove 214 of the rolling rack 206. A connecting rod 217 is hinged on the swing arm 215. The movable end of the connecting rod 217 is connected to an eccentric disk 218 to drive the swing arm 215 to swing. By driving the eccentric disk 218 to rotate through a motor (not shown in the figure), the rotational motion can be converted into the reciprocating swing of the swing arm 215, thereby driving the insert plate 216 to perform the insertion and retraction actions.

[0028] To optimize the rolling effect, the surface of the rolling belt 207 is provided with rolling teeth (not shown in the figure), and the upper surface of the lower rolling plate 205 is evenly provided with several raised strips 219 perpendicular to the rolling direction. The rolling teeth and raised strips 219 can significantly increase the friction with the outer layer of the wet wipe roll, making it roll more tightly during rolling. In addition, a rotating frame 220 is rotatably provided on the inner side of the rolling belt 207. A rolling pressure roller 222 is telescopically provided on the rotating frame 220 via bolts 221. The rolling pressure roller 222 is correspondingly arranged with the rolling teeth 206 and abuts against the inner side of the rolling belt 207. The position of the rolling pressure roller 222 abutting against the inner side of the rolling belt 207 can be changed by rotating the frame 220, and the extension length of the rolling pressure roller 222 can be changed by turning the bolts 221. The pressure and position of the rolling belt 207 on the wet wipe in the area of ​​the rolling teeth 206 can be adjusted to meet the requirements of different products.

[0029] The wetting mechanism 6 includes a water tank 61 containing a soaking solution 62 (such as disinfectant, essence, etc.). Nylon rollers 63 are located near the bottom of the water tank 61 to draw the non-woven fabric into the water tank for thorough wetting. A set of first conveying rollers 64 is located on both sides of the upper port of the water tank 61 to lift and convey the non-woven fabric soaked in the soaking solution 62, while simultaneously performing preliminary draining. The cutting mechanism 7 includes a rotating roller shaft 71 and a blade rest shaft 72. The roller shaft 71... A cutter 73 is provided on the surface along its axial direction. A groove 74 is provided on the blade pillow shaft 72 along its axial direction. A blade pillow blade 75 adapted to the cutter 73 is slidably provided in the groove 74. This sliding design makes it easy to adjust the position of the blade pillow blade 75 according to the thickness of the nonwoven fabric. A second conveying roller group 76 is provided above the roller shaft 71 and the blade pillow shaft 72 to feed the wetted nonwoven fabric smoothly into the cutting position. A support plate 77 is provided on the side of the second conveying roller group 76 near the wetting mechanism 6 to provide support before the nonwoven fabric is cut.

[0030] To ensure coordinated operation of the entire machine and improve the degree of automation, this invention features a reasonable transmission system. A set of motors (not shown in the figure) synchronously drive the first conveyor roller group 64, the second conveyor roller group 76, and the second discharge roller 210 at the entrance of the rolling mechanism 2 via a transmission chain or belt. This ensures that the material conveying speed is consistent from wetting to entering the rolling conveyor channel 213. The first discharge roller 201, the second discharge roller 210, and the third rolling roller 204 are connected by a synchronous belt to achieve synchronous rotation, ensuring that the conveying section 208 of the rolling belt 207 is in sync with the conveyor belt. Linear velocity matching between 212 and between the rolling section 209 and the third rolling roller 204; another set of motors (not shown in the figure) simultaneously drives the roller shaft 71 and the eccentric disk 218. The roller shaft 71 and the blade rest shaft 72 mesh through a pair of transmission gears (not shown in the figure) to achieve opposite rotation of the two, thereby completing the fixed-length cutting. The rotation of the eccentric disk 218 is converted into the reciprocating swing of the insert plate 216. This design ensures that for each piece of wet wipe cut, the insert plate 216 performs an insertion action to guide the wet wipe to the starting position of the rolling, and the action rhythm is precisely synchronized.

[0031] The main frame 1 is equipped with a water receiving tank 861 below the wetting mechanism 6, the cutting mechanism 7, and the rolling mechanism 2. It can collect the excess soaking liquid 62 that drips from the wet wipes during the production process, as well as the liquid that drips from the equipment, so as to facilitate centralized recycling and treatment, realize the recycling of resources, and keep the working environment clean.

[0032] The nonwoven fabric roll is unwound by the unwinding mechanism 3, folded into the required number of layers by the folding mechanism 4, and then diverted by the traction mechanism 5 to be transported to the water tank 61 of the wetting mechanism 6 for impregnation. The impregnated nonwoven fabric is lifted by the first conveyor roller group 64 and initially drained, then supported by the support plate 77 and transported by the second conveyor roller group 76 to the cutting mechanism 7. The roller shaft 71 and the blade pillow shaft 72 rotate in opposite directions, cutting the nonwoven fabric into wet wipe sheets of a specified length. The cut wet wipe sheets fall into the conveying channel 213 formed by the twisting belt 207 and the conveyor belt 212 and continue to be transported downwards. When the front end of the wet wipe sheet is transported to the appropriate position, the eccentric plate 218 causes the swing arm 215 to swing the insert plate 216. 216 is inserted between the third rolling roller 204 and the rolling belt 207 at a position slightly above the lower end of the wet wipe sheet until it abuts into the groove 214 of the rolling toothed bar 206, causing the wet wipe sheet to bend upward. As the wet wipe continues to be conveyed and the insert plate 216 retracts in time, it begins to roll under the drive of the rolling belt 207. The wet wipe roll passes through the positioning and engagement of the groove 214 of the rolling toothed bar 206, and is clamped and rolled by the third rolling roller 204. Finally, it enters the inclined space between the rolling section 209 of the rolling belt 207 and the lower rolling plate 205 with the protrusion 219. Under continuous rolling and friction, it is rolled and compacted to form a compact cylindrical wet wipe roll before being output, completing the entire rolling and forming process.
