Description

Technical Field

[0001] The invention relates to the technical field of glass fiber cloth processing equipment, in particular to a material guide roller of glass fiber cloth drying equipment. Background Art

[0002] Glass fiber cloth needs to be properly surface treated during production, that is, a surface treatment agent (generally a wetting agent, which includes adhesives, lubricants, emulsifiers and other ingredients) is coated on the surface of the glass fiber. The surface treatment agent forms a film on the surface, which not only helps to enhance the strength of the fabric, but also improves the wear resistance and waterproof properties of the fabric. During surface treatment, the glass fiber cloth is first sizing in an impregnation tank containing the wetting agent, and then conveyed to the dryer through the cloth guide roller for drying and film formation.

[0003] For example, a material guiding device of a glass fiber cloth drying equipment with publication number CNCN214736678U has the following defects when guiding the glass fiber cloth, such as: the hot air flow blown out from the air outlet in the heating chamber is directly blown to the suspended end surface of the glass fiber cloth between two adjacent groups of support tubes. If the air flow is large, it will undoubtedly blow the suspended end surface of the glass fiber cloth to bulge, which is easy to affect its safety and quality. Summary of the invention

[0004] The purpose of the present invention is to provide a material guide roller for glass fiber cloth drying equipment.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0006] A material guide roller of a glass fiber cloth drying device comprises a box body and a cloth guide roller located in the box body, wherein both ends of the cloth guide roller are provided with a rotating shaft penetrating the side wall of the box body:

[0007] The cloth guide roller is provided with an air cavity, wherein the outer wall of the cloth guide roller is axially buckled with multiple groups of supporting mechanisms, wherein the supporting mechanisms include two groups of inclined plates axially arranged on the outer side of the cloth guide roller, wherein an eight-shaped structure is formed between the two groups of inclined plates, and an arc-shaped plate is arranged at the smallest opening end of the two groups of inclined plates, and air outlet holes are evenly arranged on the side walls of the inclined plates, wherein the side walls of the cloth guide roller corresponding to the two groups of inclined plates are evenly provided with connecting holes connected with the air cavity;

[0008] The rotating shaft is provided with an installation channel connected to the wind cavity, one group of the installation channels is provided with an air inlet pipe fixed to the side wall of the box body through a bracket, and a plurality of air inlets are provided on the side wall of the air inlet pipe in the wind cavity, and a boss is also provided at the end of the air inlet pipe in the wind cavity, wherein a rotating shaft is fixed on the boss through a bearing, and one end of the rotating shaft passes through another group of installation channels and is connected to the motor, fan blades are provided on the rotating shaft in the wind cavity, and an L-shaped frame for fixing the motor is provided on the side wall of the box body.

[0009] Preferably, the number of the supporting mechanisms is at least five groups, wherein multiple groups of supporting mechanisms are evenly arranged on the outer side wall of the cloth guide roller.

[0010] Preferably, the rotating shaft and the air inlet pipe are adapted to the inner diameter of the corresponding installation channel.

[0012] Preferably, the cloth guide roller is composed of a cylinder and circular plates located at both ends of the cylinder, wherein the circular plates are fixed to the two ends of the cylinder by bolts.

[0013] The beneficial effects of the present invention are as follows: the present invention introduces a hot air flow into the air cavity through the air inlet pipe and the air inlet, wherein the air flow enters the cavity formed by the two groups of inclined plates and the arc-shaped plates through the connecting port, and then is obliquely ejected from the air outlet to contact the end face of the glass fiber cloth. By bending the hot air flow so that it is blown out obliquely and contacts the glass fiber cloth, the situation in which the hot air flow is radially blown onto the end face of the glass fiber cloth, causing the glass fiber cloth to produce large fluctuations or arches, is prevented, thereby improving the safety and quality of the glass fiber cloth; at the same time, the motor drives the fan blades to rotate in the air cavity through the rotating shaft, thereby disturbing the air flow in the air cavity to accelerate its flow rate, so that the gas in the air cavity can be quickly discharged through the connecting hole and the air outlet to contact the glass fiber cloth, thereby drying it.

DETAILED DESCRIPTION

[0017] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.

[0018] A guide roller of a glass fiber cloth drying device comprises a box body 1 and a cloth guide roller 2 located in the box body 1, wherein both ends of the cloth guide roller 2 are provided with a rotating shaft 3 penetrating the side wall of the box body 1:

[0019] The cloth guide roller 2 is provided with an air cavity 4, wherein the outer wall of the cloth guide roller 2 is axially buckled with multiple groups of support mechanisms 5, wherein the support mechanisms 5 include two groups of inclined plates 51 axially arranged on the outer side of the cloth guide roller 2, wherein an eight-shaped structure is formed between the two groups of inclined plates 51, and an arc plate 52 is arranged at the smallest opening end of the two groups of inclined plates 51, and the end surface of the arc plate 52 is provided with anti-slip grooves, and air outlet holes 6 are evenly arranged on the side walls of the inclined plates 51, wherein the side walls of the cloth guide roller 2 corresponding to the two groups of inclined plates 51 are evenly provided with connecting holes 7 connected with the air cavity 4;

[0020] The rotating shaft 3 is provided with an installation channel connected to the wind cavity 4, one group of the installation channels is provided with an air inlet pipe 8 fixed to the side wall of the box body 1 through a bracket 9, and a plurality of air inlet ports 10 are provided on the side wall of the air inlet pipe 8 in the wind cavity 4, a boss 11 is further provided at the end of the air inlet pipe 8 in the wind cavity 4, wherein a rotating shaft 13 is fixed on the boss 11 through a bearing 12, and one end of the rotating shaft 13 passes through another group of installation channels and is connected to a motor 14, a fan blade 15 is provided on the rotating shaft 13 in the wind cavity 4, and an L-shaped frame 16 for fixing the motor 14 is provided on the side wall of the box body 1.

[0021] like Figure 2 As shown, the number of the supporting mechanisms 5 is at least five groups, wherein multiple groups of supporting mechanisms 5 are evenly arranged on the outer side wall of the cloth guide roller 2 .

[0022] In this embodiment, the rotating shaft 13 and the air inlet pipe 8 are adapted to the inner diameter of the corresponding installation channel.

[0023] In this embodiment, the cloth guide roller 2 is composed of a cylinder and circular plates located at both ends of the cylinder, wherein the circular plates are fixed to both ends of the cylinder by bolts.

[0024] When in use, the cloth guide roller 2 is pressed against the glass fiber cloth, and the arc plate 52 on the supporting mechanism 5 is in contact with the glass fiber cloth to reduce the area covered by the corresponding end surface of the glass fiber cloth, thereby reducing the probability of the slurry on the surface of the glass fiber cloth being scratched;

[0025] At the same time, the hot air flow is introduced into the air cavity 4 through the air inlet pipe 8 and the air inlet 10, wherein the air flow enters the cavity formed between the two groups of inclined plates 51 and the arc-shaped plate 52 through the connecting hole 7, and then is obliquely ejected from the air outlet 6 and contacts the end surface of the glass fiber cloth. By bending the hot air flow so that it is blown out obliquely and contacts the glass fiber cloth, the situation in the past where the hot air flow is radially blown onto the end surface of the glass fiber cloth, causing the end surface of the glass fiber cloth to have a large fluctuation or arching, is prevented, thereby improving the safety and quality of the glass fiber cloth;

[0026] At the same time, the motor 14 drives the fan blades 15 to rotate in the wind cavity 4 through the rotating shaft 13, thereby disturbing the airflow in the wind cavity 4 to accelerate its flow rate, so that the gas in the wind cavity 4 can be quickly discharged through the connecting hole 7 and the air outlet 6 to contact the glass fiber cloth, thereby drying it.

[0027] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
