Description

Technical Field

[0001] This utility model relates to the field of papermaking wire production technology, and in particular to a drying device for producing monofilament papermaking wire. Background Technology

[0002] Monofilament papermaking mesh is a key filter material used in papermaking for paper forming. It is mainly made of single synthetic fibers through precision weaving. Its structure is usually a multi-layered interwoven mesh structure, characterized by uniform pore size, smooth surface, and high strength. It can effectively support fiber suspension and achieve dewatering and forming. This material is widely used in the production of cultural paper, packaging paper, and specialty paper. In the paper forming process, it has the functions of carrying fibers, uniformly dewatering, and transferring paper. It is an important component to ensure papermaking efficiency and paper quality.

[0003] In the existing technology, there is a drying process in the production of monofilament papermaking mesh. In the traditional method, the monofilament papermaking mesh is dried directly with hot air. However, the monofilament material has shrinkage stress, which may cause the monofilaments to entangle or stick together, resulting in blockage or deformation of the papermaking mesh, affecting the flatness of the papermaking mesh, increasing the scrap rate, and moisture is easy to exist inside the papermaking mesh, increasing the drying time and hindering the improvement of the working efficiency of the drying device. Therefore, in order to solve the above problems, this utility model proposes a drying device for the production of monofilament papermaking mesh. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drying device for monofilament papermaking mesh production. A motor drives a stretching roller to stretch and vibrate the monofilament papermaking mesh, offsetting the shrinkage stress of the material, preventing mesh blockage or deformation caused by monofilament entanglement or adhesion, reducing waste rate, ensuring mesh tension, reducing surface roughness or protrusions, and meeting the flatness requirements. The vibration causes internal moisture to migrate to the surface, reducing the moisture content of the monofilament papermaking mesh, shortening the required drying time, and improving the device's working efficiency.

[0005] This utility model provides the following technical solution: a drying device for monofilament papermaking wire production, comprising a shell, a cavity in the middle of the shell, a motor fixedly installed at the rear of the cavity, a rotating handle fixedly connected to the output shaft of the motor via a coupling, a traction rod movably connected to the front of the rotating handle via a shaft, a lifting rod movably connected to the bottom of the traction rod via a shaft, the lifting rod being movably sleeved with the bottom of the cavity, a connecting block fixedly installed at the bottom of the lifting rod, and a tension roller movably connected to the bottom of the connecting block via a shaft, the tension rollers being two in number and symmetrically distributed front and back, the motor driving the tension rollers to stretch and shake the monofilament papermaking wire, offsetting the material shrinkage stress, avoiding mesh blockage and deformation due to monofilament entanglement or adhesion, reducing surface roughness or protrusions, meeting flatness requirements, and the shaking causing internal moisture migration, reducing moisture content and thus shortening the required drying time, improving the working efficiency of the device.

[0006] Preferably, the left and right sides of the housing are respectively movably fitted with conveying rollers, and four guide rollers are uniformly movably fitted in the inner cavity of the housing. Monofilament papermaking mesh is provided on the conveying rollers and guide rollers. The monofilament papermaking mesh is transported to the inner cavity of the housing by the conveying rollers, and the guide rollers provide guidance for the monofilament papermaking mesh, so that the monofilament papermaking mesh can move continuously in the device, which is beneficial to the continuous operation of the drying device.

[0007] Preferably, a hot air blower is symmetrically and fixedly fitted onto the front and rear parts of the housing. A hot air pipe is fixedly installed on the side of the hot air blower facing the inner cavity of the housing. There are two hot air pipes, which are symmetrically distributed vertically. When the monofilament papermaking web moves to the right side of the inner cavity of the housing, the hot air blower is turned on. The hot air blower blows hot air onto the monofilament papermaking web through the hot air pipe to dry it. The hot air pipe and the monofilament papermaking web are at a certain angle to avoid direct blowing that would cause the monofilament papermaking web to curl.

[0008] Preferably, a guide pipe is provided at the top of the inner cavity of the housing and above the cavity. The right end of the inner cavity of the guide pipe is located above the hot air pipe. Five drying plates are uniformly fixed in the middle of the inner cavity of the guide pipe. The hot air flow generated by drying enters the guide pipe and passes through multiple drying plates to remove moisture, which facilitates the reuse of the hot air flow and improves the energy utilization efficiency of the device.

[0009] Preferably, a fixing frame is fixedly installed at the left end of the inner cavity of the guide pipe, and a guide fan is fixedly installed in the middle of the fixing frame. A maintenance plate is movably connected to the upper part of the shell above the drying plate via a shaft. An exhaust port is opened on the upper part of the shell to the left of the maintenance plate. The hot airflow is blown towards the monofilament papermaking mesh on the left side of the inner cavity of the shell by the guide fan to pre-dry the monofilament papermaking mesh. The water vapor generated during drying is discharged through the exhaust port. The maintenance plate can be opened to replace the drying plate periodically to ensure the drying effect of the hot airflow.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The motor drives the transmission mechanism, causing the stretching roller to stretch and vibrate the monofilament papermaking mesh. This applies a certain stretching force to the monofilament papermaking mesh, counteracting the shrinkage stress of the material, eliminating local stress concentration, and preventing mesh blockage or deformation caused by monofilament entanglement or adhesion. This reduces manual sorting costs and waste rate. The stretching ensures the mesh is taut, reducing surface roughness or protrusions and meeting the flatness requirements of the formed mesh. The up-and-down vibration of the material causes internal moisture to migrate to the surface. Combined with the micro-tension stress during stretching, this reduces the moisture content of the monofilament papermaking mesh, shortens the required drying time, and improves the working efficiency of the drying equipment.

[0012] 2. During the drying process, the hot airflow enters the guide pipe. The hot airflow passes through multiple drying plates to reduce its water content. Then, driven by the guide fan, the hot airflow blows towards the monofilament papermaking mesh on the left side of the inner cavity of the shell, pre-drying the monofilament papermaking mesh. Pre-drying reduces the moisture content of the monofilament papermaking mesh, reducing the amount of moisture that needs to be removed when it enters the hot air drying equipment, thereby shortening the drying time, reducing the processing pressure of the hot air blower, extending the service life of the heating element, and reducing maintenance costs. Traditional direct high-temperature drying may cause some polymer thermal degradation due to excessive temperature difference, affecting the strength of the monofilament papermaking mesh. Gradient temperature rise drying avoids sudden thermal damage to the monofilament papermaking mesh and ensures a high yield rate. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 A drying device for producing monofilament papermaking webs includes a housing 1. A cavity 2 is formed in the middle of the inner cavity of the housing 1. A motor 3 is fixedly installed at the rear of the cavity 2. A rotating handle 4 is fixedly connected to the output shaft of the motor 3 via a coupling. A traction rod 5 is movably connected to the front of the rotating handle 4 via a shaft. A lifting rod 6 is movably connected to the bottom of the traction rod 5 via a shaft. The lifting rod 6 is movably sleeved with the bottom of the cavity 2. A connecting block 7 is fixedly installed at the bottom of the lifting rod 6. Two tension rollers 8 are movably connected to the bottom of the connecting block 7 via a shaft. Conveying rollers 9 are movably sleeved on the left and right sides of the housing 1. Four guide rollers 10 are evenly movably sleeved in the inner cavity of the housing 1. Monofilament papermaking webs 11 are mounted on the conveying rollers 9 and the guide rollers 10. The monofilament papermaking webs 11 are transported to the inner cavity of the housing 1 via the conveying rollers 9 and the guide rollers 10. 1. Provides guidance. During the movement of the monofilament papermaking mesh 11, the motor 3 is started, which drives the rotating handle 4 to rotate. The rotating handle 4 drives the traction rod 5 to swing. The traction rod 5 drives the lifting rod 6 to move up and down. The lifting rod 6 drives the stretching roller 8 to move up and down through the connection of the connecting block 7. This causes the stretching roller 8 to stretch and shake the monofilament papermaking mesh 11. By applying a certain stretching force to the monofilament papermaking mesh 11, the shrinkage stress of the material is offset, local stress concentration is eliminated, and mesh blockage or deformation caused by monofilament entanglement or adhesion is avoided. This reduces manual sorting costs and waste rate. Stretching ensures that the mesh is taut, reduces surface roughness or protrusions, and meets the requirements for the flatness of the formed mesh. The up and down shaking of the material causes the internal moisture of the material to migrate to the surface. Combined with the micro-tension stress during stretching, the moisture content of the monofilament papermaking mesh 11 is reduced, the required drying time is shortened, and the working efficiency of the drying device is improved.

[0020] Hot air blowers 12 are symmetrically fixedly fitted to the front and rear parts of the housing 1. Hot air pipes 13 are fixedly installed on the side of the hot air blower 12 facing the inner cavity of the housing 1. There are two hot air pipes 13, symmetrically distributed vertically. A guide pipe 14 is opened at the top of the inner cavity of the housing 1, above the cavity 2. The right end of the guide pipe 14 is above the hot air pipe 13. Five drying plates 15 are evenly fixedly installed in the middle of the inner cavity of the guide pipe 14. A fixing frame 16 is fixedly installed at the left end of the inner cavity of the guide pipe 14. A guide fan 17 is fixedly installed in the middle of the fixing frame 16. A maintenance plate 18 is movably connected to the upper part of the housing 1, above the drying plate 15, via a shaft. An exhaust port 19 is opened on the upper part of the housing 1, to the left of the maintenance plate 18. When the monofilament papermaking mesh 11 moves to the right side of the inner cavity of the housing 1, the hot air blower 12, and the hot air blower 12 blows hot air onto the monofilament papermaking mesh 11 through the hot air pipe 13, thereby allowing the papermaking mesh to enter the inner cavity. The hot airflow generated during drying enters the guide pipe 14 and passes through multiple drying plates 15 for drying. The dried hot airflow is then blown by the guide fan 17 towards the monofilament papermaking mesh 11 on the left side of the inner cavity of the housing 1 for pre-drying. Pre-drying reduces the moisture content of the monofilament papermaking mesh 11, reducing the amount of moisture that needs to be removed when it enters the hot air blower 12 drying equipment, thereby shortening the drying time. Traditional direct high-temperature drying may cause some polymer thermal degradation due to excessive temperature difference, affecting the strength of the monofilament. Gradient heating drying avoids sudden heat damage to the monofilament papermaking mesh 11. Pre-drying reduces the processing pressure of the hot air blower 12, which can reduce the operating power of the equipment, extend the service life of the heating element, and reduce maintenance costs. The water vapor generated during drying is discharged through the exhaust port 19. The inspection plate 18 can be opened to periodically replace the drying plates 15 to ensure the drying effect of the hot airflow.

[0021] Working principle: The monofilament papermaking web 11 is transported to the inner cavity of the housing 1 by the conveying roller 9. The guide roller 10 provides guidance for the monofilament papermaking web 11. During the movement of the monofilament papermaking web 11, the motor 3 is started, which drives the rotating handle 4 to rotate. The rotating handle 4 drives the traction rod 5 to swing. The traction rod 5 drives the lifting rod 6 to move up and down. The lifting rod 6 drives the stretching roller 8 to reciprocate up and down through the connecting block 7, so that the stretching roller 8 stretches and shakes the monofilament papermaking web 11. When the monofilament papermaking web 11 moves to the inner cavity of the housing 1... When the right side is turned on, the hot air blower 12 blows hot air through the hot air pipe 13 to the monofilament papermaking mesh 11 for drying. The hot air flow generated by drying enters the guide pipe 14 and passes through multiple drying plates 15 for drying. The dried hot air flow is blown by the guide fan 17 to the monofilament papermaking mesh 11 in the left side of the inner cavity of the housing 1 for pre-drying. The water vapor generated by drying is discharged through the exhaust port 19. The maintenance plate 18 can be opened to replace the drying plates 15 periodically to ensure the drying effect of the hot air flow.
