[0001] This utility model relates to the field of paper towel processing technology, and in particular to a paper towel drying mechanism. Background Technology

[0002] Paper towels, also known as household paper, include napkins, handkerchiefs, toilet paper, facial tissues, etc., and are commonly used in daily life. Their components include chlorine, bleach, and wood pulp, which are renewable resources. With the increasing development of the catering and hotel industries, the demand for paper towels for cleaning is constantly expanding, and their usage is continuously rising in various daily situations. During paper towel processing, paper towels that have absorbed large amounts of water and disinfectants during production need to be dried before subsequent cutting.

[0003] Patent CN221484126U discloses "a drying device for paper towel production, including a housing and a retaining plate, wherein an air heating component is fixedly installed inside the housing. In this drying device for paper towel production, while heating the paper towels on the conveyor belt, the motor drives the first pulley assembly sleeved on the surface of the first rotating rod to rotate. The first movable rod driven by the first pulley assembly drives the second movable rod to rotate through the first bevel gear and the second bevel gear. The cooling fan at the end of the second movable rod blows the hot air inside the device outward to avoid the formation of high-temperature water vapor inside, which would affect the lifespan of the internal mechanical structure of the device."

[0004] Regarding the aforementioned technologies, the inventors believe that in actual use, the paper towels absorb water and disinfectant, resulting in excessive moisture. The air heating component takes a long time to dry the paper towels with excessive moisture, thus reducing the drying efficiency of the equipment. Therefore, improvements are needed.

[0014] By adopting the above technical solution, the hot air blower can send hot air into the upper and lower drying pipes through the guide hood. The upper and lower drying pipes can dry the top and bottom of the paper towel, thereby reducing the drying dead area and improving the drying efficiency.

[0015] In summary, this utility model has at least one of the following beneficial effects:

[0016] 1. By squeezing the paper towels with the idler rollers and the squeeze rollers, the liquid inside the paper towels can be squeezed out, thereby reducing the moisture content of the paper towels and reducing the drying time of the paper towels by the hot air blower, thus improving the drying efficiency.

[0023] The following is combined with Figure 1-4 The utility model is described in further detail.

[0024] This utility model discloses a paper towel drying mechanism, referring to... Figure 1-2 The device includes a body 1, a squeezing mechanism, and a hot air blower 3. The paper towel is in the shape of an uncut strip. The body 1 is the housing of the drying mechanism. The body 1 has through holes 11 on both sides for the paper towel to pass through. The paper towel can enter and exit the body 1 through the through holes 11. A traction mechanism such as a winding roller can be set outside the device to pull the dried paper towel.

[0025] Reference Figure 2 The squeezing mechanism includes a roller 2 rotatably mounted inside the machine body 1 for carrying and conveying paper towels, a squeezing roller 21 movably mounted inside the machine body 1 for pressing down and conveying the paper towels on top of the roller 2, and a telescopic mechanism installed inside the machine body 1 for driving the squeezing roller 21 to rise and fall. The roller 2 can lift the paper towels on top, and the squeezing roller 21 is located directly above the roller 2.

[0026] After the squeezing roller 21 moves down, it can work with the fixed support roller 2 to squeeze the paper towel in the middle, thereby squeezing out the liquid in the paper towel and reducing the moisture in the paper towel. The telescopic mechanism can drive the squeezing roller 21 to move up and down, thereby adjusting the squeezing force of the squeezing roller 21 on the paper towel. For example, if the distance between the squeezing roller 21 and the support roller 2 is small, the squeezing force on the paper towel is large, and if the distance between the squeezing roller 21 and the support roller 2 is large, the squeezing force on the paper towel is small.

[0027] Reference Figure 2-3 The telescopic mechanism includes an electric push rod 23 fixedly installed on the top of the inner wall of the machine body 1, and a connecting frame 22 fixedly installed at the bottom of the electric push rod 23. The extrusion roller 21 is rotatably connected to the bottom inner side of the connecting frame 22. The electric push rod 23 can drive the connecting frame 22 and the extrusion roller 21 to move up and down. The connecting frame 22 can connect the electric push rod 23 and the extrusion roller 21.

[0028] Reference Figure 2-3 The outer walls of the machine body 1 and the connecting frame 22 are respectively fixedly installed with several motors 24 for driving the idler roller 2 and the squeeze roller 21 to rotate. The several motors 24 can be synchronous motors or other motors that can rotate synchronously. The synchronous rotation is a public technology and will not be described in detail here. The several motors 24 can drive the idler roller 2 and the squeeze roller 21 to rotate, thereby squeezing and conveying the paper towel.

[0029] Reference Figure 2 A drain pipe 12 is fixedly provided at the bottom of the inner wall of the machine body 1. The drain pipe 12 can discharge the water that is squeezed out by the support roller 2 and the squeezing roller 21 and flows to the bottom of the machine body 1.

[0030] Reference Figure 2-4 The machine body 1 is equipped with a cleaning mechanism for cleaning the idler roller 2 and the extrusion roller 21 after the connecting frame 22 moves upward. The cleaning mechanism includes an upper cleaning component 4 located inside the machine body 1 for cleaning the surface of the extrusion roller 21 after the connecting frame 22 moves upward, and a lower cleaning component 41 located at the bottom of the connecting frame 22 for cleaning the surface of the idler roller 2 after the connecting frame 22 moves upward. A fixing plate 14 located above the extrusion roller 21 is fixedly provided on the inner wall of the machine body 1. The upper cleaning component 4 is fixedly installed at one end of the fixing plate 14. A U-shaped frame 25 is fixedly provided on one side of the bottom of the connecting frame 22. The lower cleaning component 41 is fixedly provided at the bottom inside the U-shaped frame 25. The upper cleaning component 4 and the lower cleaning component 41 can be made of objects with cleaning effect, such as sponges.

[0031] The fixing plate 14 can support and fix the upper cleaning component 4, and the U-shaped frame 25 can connect the connecting frame 22 and the lower cleaning component 41, and support and fix the lower cleaning component 41. One end of the upper cleaning component 4 will abut against the outer surface of the upward-moving extrusion roller 21, and the top of the lower cleaning component 41 will abut against the outer surface of the fixed support roller 2 after it moves upward.

[0032] When the electric push rod 23 shortens, it will drive the connecting frame 22, the squeezing roller 21, the U-shaped frame 25, and the lower cleaning component 41 to move upward as a whole. After moving upward, the outer surface of the squeezing roller 21 will come into contact with the upper cleaning component 4, so that the upper cleaning component 4 can clean the outer surface of the squeezing roller 21 in conjunction with the rotation of the squeezing roller 2. After moving upward, the lower cleaning component 41 will come into contact with the outer surface of the idler roller 2, so that the lower cleaning component 41 can clean the outer surface of the idler roller 2 in conjunction with the rotation of the idler roller 2. This makes it difficult for foreign matter adhering to the outer surfaces of the idler roller 2 and the squeezing roller 21 to be wiped onto the paper towel, thereby ensuring the quality of the paper towel after drying.

[0033] Reference Figure 2-3 A hot air blower 3 is installed inside the machine body 1 to dry the squeezed paper towel. A guide hood 31 is fixedly provided at the blowing end of the hot air blower 3. An upper drying pipe 32 for blowing and drying the top of the paper towel is fixedly provided at the bottom of one side of the guide hood 31. A lower drying pipe 33 for blowing and drying the bottom of the paper towel is fixedly provided at the bottom of the side of the guide hood 31 away from the upper drying pipe 32. The blowing end of the upper drying pipe 32 is directly facing the top of the paper towel, while the bottom end of the lower drying pipe 33 goes around the paper towel and is directly facing the bottom of the paper towel. The guide hood 31 can send the hot air from the hot air blower 3 into the upper drying pipe 32 and the lower drying pipe 33.

[0034] The hot air blower 3 can send hot air into the upper drying pipe 32 and the lower drying pipe 33 through the guide shroud 31. The upper drying pipe 32 and the lower drying pipe 33 can dry the top and bottom of the paper towel, thereby reducing the drying dead corner and improving the drying efficiency.

[0035] Reference Figure 1-2 A fan 13 is fixedly installed on one side of the machine body 1 to exhaust the high-temperature water vapor inside the machine body 1. A maintenance door is provided on one side of the machine body 1. The fan 13 can exhaust the high-temperature water vapor generated after the paper towels are dried inside the machine body 1, so that high-temperature water vapor will not easily form inside the machine body 1 and affect the life of its internal components.

[0036] The implementation principle of a paper towel drying mechanism according to an embodiment of this utility model is as follows:

[0037] In use, the electric push rod 23 is extended and retracted to drive the connecting frame 22 and the squeezing roller 21 to rise and fall. When the squeezing roller 21 moves down, it can press down the paper towel on the top of the support roller 2. Then, several motors 24 are turned on to drive the support roller 2 and the squeezing roller 21 to rotate, thereby squeezing and conveying the paper towel. This can squeeze out the liquid in the paper towel, reduce the moisture in the paper towel, reduce the subsequent drying time of the paper towel, and improve the drying efficiency.

[0038] Next, the hot air blower 3 can be turned on. The hot air blower 3 can send hot air into the upper drying pipe 32 and the lower drying pipe 33 through the guide shroud 31. The upper drying pipe 32 and the lower drying pipe 33 can dry the top and bottom of the paper towel, thereby reducing the drying dead corner and improving the drying efficiency.

[0039] When it is necessary to clean the idler roller 2 and the squeeze roller 21, the electric push rod 23 can be shortened to drive the connecting frame 22, the squeeze roller 21, the U-shaped frame 25 and the lower cleaning component 41 to move upward as a whole. After moving upward, the outer surface of the squeeze roller 21 will contact the upper cleaning component 4, so that the upper cleaning component 4 can clean the outer surface of the squeeze roller 21 in conjunction with the rotation of the squeeze roller 21. After moving upward, the lower cleaning component 41 will contact the outer surface of the idler roller 2, so that the lower cleaning component 41 can clean the outer surface of the idler roller 2 in conjunction with the rotation of the idler roller 2, thereby ensuring the quality of the paper towel after drying.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
