DETAILED DESCRIPTION
[0026] The specific implementation methods of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0027] like Figure 1 As shown, a toilet paper roll comprises an integrated structure formed by winding a continuous toilet paper, wherein a small portion of the toilet paper layer wound inside is an inner roll layer 11, and the inner roll layer 11 is in a bonded and hardened state. This state is formed by humidifying the toilet paper of the inner roll layer 11 and then air-drying, air-drying or baking. The liquid used for humidification can be water or a viscous glue liquid. The majority of the toilet paper layer wound outside is an outer roll layer 12, and the outer roll layer 12 is in a soft state that can be used by people. The inner roll layer 11 is used to replace the traditional paper tube and plays a similar role to the traditional paper tube. Specifically, the inner roll layer 11 is a hollow structure, which makes it easy to put the toilet paper roll on an axis-like structure so that it can rotate flexibly and is convenient for users to extract. The inner roll layer 11 can provide support for the outer roll layer 12. The circumference of the inner roll layer 11 is corrugated. This shape increases the interlayer contact area of the toilet paper in the inner roll layer 11, which is beneficial to the bonding of the inner roll layer 11 after drying to form an overall structure, and prevents the inner roll layer 11 from loosening and softening.
[0028] like Figure 2-Figure 5As shown, a rewinding device for producing the toilet paper roll includes a body 21 and an inner support rod 22, wherein the body 21 is provided with a rewinding station and a core-pulling station, two rewinding rollers 211 are horizontally provided at the rewinding station, and the two rewinding rollers 211 are rotatably connected to the body 21, and the two rewinding rollers 211 are driven to rotate by a motor. Since the motor belongs to a conventional power mechanism, it is not shown in the accompanying drawings, a pressure roller 212 is horizontally provided above the two rewinding rollers 211, and the end of the pressure roller 212 is rotatably connected to a swing arm 2121, one end of the swing arm 2121 is rotatably connected to the body 21, and the top of the body 21 is rotatably connected to a cylinder 2122, and the telescopic rod of the cylinder 2122 is rotatably connected to the other end of the swing arm 2121 Dynamic connection, when the cylinder 2122 is extended, it pushes the swing arm 2121 to swing downward, so that the pressure roller 212 falls; when the cylinder 2122 is shortened, it pulls the swing arm 2121 to swing upward, so that the pressure roller 212 rises. A water distribution pipe 213 is also provided above the two rewinding rollers 211, and a plurality of atomizing nozzles 2131 are evenly arranged on the water distribution pipe 213 along the axial direction of the rewinding roller 211. The plurality of atomizing nozzles 2131 are all facing between the two rewinding rollers 211. A water spraying power element is provided on the machine body 21. In this embodiment, the water spraying power element is a pneumatic sprayer 2132. The water inlet of the pneumatic sprayer 2132 is connected to the water tank, the air inlet is connected to the external air source equipment, and the water outlet is connected to the water distribution pipe 213.
[0029] The inner support rod 22 is a slender rod having a plurality of protrusions 221 and recesses 222 alternately provided around the circumference thereof to form a corrugated outer circumference. A baffle 223 is fixedly connected to one end of the inner support rod 22 .
[0030] During the rewinding operation, the toilet paper needs to be laid on the two rewinding rollers 211, and the inner support rod 22 is placed between the two rewinding rollers 211 to press the toilet paper. The body 21 in front of the rewinding roller 211 is provided with a blowing hole 214 facing upward and rearward, and the blowing hole 214 is connected to the external air source equipment. The air blown out by the blowing hole 214 will fold the end of the toilet paper back and cover it on the inner support rod 22, and then start the cylinder 2122 to make the pressure roller 212 press the toilet paper above the inner support rod 22, and then start the motor to make the two rewinding rollers 211 rotate in the same direction, driving the inner support rod 22 to rotate and wind the toilet paper, and start the pneumatic sprayer 2132 at the same time as starting the motor, so that multiple atomizing nozzles 2131 spray water mist to the toilet paper wound on the inner support rod 22, so that it absorbs water and sticks to the outer peripheral surface of the inner support rod 22, forming a connection with the outer peripheral surface of the inner support rod 22 The surface has a corresponding circumferential corrugated shape. After the inner support rod 22 rotates a certain number of times, the pneumatic sprayer 2132 stops working, so that water mist is no longer sprayed on the subsequently wound toilet paper. As a result, only a small part of the inner toilet paper layer of the rewound toilet paper roll is humidified, and then naturally bonded and hardened after drying to form the inner roll layer 11. If it is necessary to enhance the bonding and hardening effect of the inner roll layer 11, an appropriate amount of viscous glue can be added to the sprayed water. Since most of the toilet paper layers on the outside of the toilet paper roll are not humidified, they remain soft, forming an outer roll layer 12 for people to use. During the rewinding process, as the diameter of the toilet paper roll gradually increases, the pressure roller 212 gradually rises, and the cylinder 2122 acts as an air spring, so that the pressure roller 212 maintains a certain pressure on the toilet paper roll, and its function is to make the toilet paper roll tightly wound.
[0031] The core pulling station is located in front of the rewinding station. Two rollers 216 are horizontally arranged at the core pulling station. The two rollers 216 are rotatably connected to the machine body 21. A fixed plate 217 and a push plate 218 are provided between the two rollers 216. The fixed plate 217 is fixedly connected to the machine body 21. A first opening groove 2171 for avoiding the inner support rod 22 is provided on the fixed plate 217. A second opening groove 2181 for avoiding the inner support rod 22 is provided on the push plate 218. The bottom of the push plate 218 is fixedly connected to a slide 2182. The slide 2182 is rotated along the roller 217. 16 is axially slidably connected to the body 21, and the two ends of the sliding stroke of the slide 2182 on the body 21 are rotatably connected with a wheel 2192, a transmission belt 2193 is connected between the two wheels 2192, and the transmission belt 2193 is fixedly connected to the slide 2182. A servo motor 2191 is also provided on the body 21, and the servo motor 2191 is transmission-connected to a wheel 2192. The servo motor 2191 drives the wheel 2192 and the transmission belt 2193 to rotate, which can drive the slide 2182 and the push plate 218 to slide back and forth.
[0032] The rewound toilet paper roll is rolled onto the two rollers 216 so that the inner support rod 22 inside it is stuck in the first opening groove 2171 and the second opening groove 2181, and the baffle 223 on the inner support rod 22 is located on the side of the fixed plate 217 away from the push plate 218. A cutting and gluing mechanism 215 is provided between the rewinding station and the core pulling station. The cutting and gluing mechanism 215 is used to cut the toilet paper and apply glue to the end of the toilet paper in front of it. The cutting and gluing mechanism 215 is a prior art and its structure will not be described in detail here. According to the working principle, the cut and glued toilet paper roll is rolled on two rollers 216 until the end of the toilet paper coated with glue is adhered to the toilet paper roll, and then the servo motor 2191 is started to push the push plate 218 in the direction away from the fixed plate 217. The baffle 223 on the inner support rod 22 is blocked by the fixed plate 217, so that the inner support rod 22 cannot move with the toilet paper roll, thereby pulling the inner support rod 22 out of the toilet paper roll, and the inner roll layer 11 in the toilet paper roll forms a hollow structure.
[0033] In actual application, two inner support rods 22 can be equipped, and the two inner support rods 22 can be used alternately in the rewinding station and the core pulling station. When the core pulling operation is performed on the previous toilet paper roll, the next toilet paper roll can be rewound at the same time, thereby reducing waiting time and improving work efficiency.
