Description

Technical Field

[0001] The invention relates to the technical field of glass fiber cloth processing equipment, in particular to a device for uniformly coating glass fiber cloth impregnation liquid. Background Art

[0002] Glass fiber cloth is an inorganic non-metallic material made of glass fiber as raw material. It has excellent mechanical properties, heat resistance, insulation and chemical stability. It is widely used in civil engineering, industrial manufacturing, electronics and electrical fields. Glass fiber cloth impregnation is a key process link in the production and application of glass fiber cloth. The impregnation effect directly affects the performance and application quality of glass fiber cloth.

[0003] During the impregnation process, the glass fiber cloth is prone to incomplete impregnation, and the impregnation liquid is difficult to dry quickly after impregnation, which affects production. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a device for uniformly coating glass fiber cloth with impregnating liquid, which solves the problem that the glass fiber cloth is easily not thoroughly impregnated during the impregnation process and the impregnating liquid is difficult to dry quickly after impregnation, thus affecting production.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a device for uniformly coating glass fiber cloth impregnation liquid, comprising a processing box, a servo motor and a brake cylinder, two transmission screws are arranged inside the processing box, and the positions of the two transmission screws are symmetrically distributed front and back about the middle position of the processing box, and the outer surfaces of the two transmission screws are provided with two sections of threads with opposite rotation directions and equal lengths, and the outer surfaces of the two transmission screws are threadedly sleeved with two adjusting thread seats, and the two adjusting thread seats threadedly sleeved on the outer surface of the same transmission screw are respectively threadedly sleeved on the outer surfaces of the two sections of threads, and the two transmission screws are connected by a transmission belt, and two mounting rods are arranged inside the processing box, and the two ends of the mounting rods are respectively fixedly connected to the side walls of the two adjusting thread seats, and the opposite side walls of the two mounting rods are fixedly connected with a plurality of limit clips.

[0006] Preferably, two mounting shafts are provided inside the processing box body, and the mounting shafts are transmission-connected to the transmission screw through a transmission belt, and a plurality of negative pressure fans are fixedly connected to one end of the mounting shaft away from the inner wall of the processing box body, and the driving end of the servo motor passes through the side wall of the processing box body and extends into the interior thereof and is fixedly connected to one of the mounting shafts, and the other mounting shaft is rotationally connected to one end of the inner wall of the processing box body close to the inner wall of the processing box body.

[0007] Preferably, the output end of the braking cylinder penetrates through the bottom of the processing box body and extends into the interior thereof, and is fixedly connected with an adjusting piston plate. The outer side wall of the adjusting piston plate is attached to the inner side wall of the processing box body, and the interior of the processing box body is filled with an infiltration liquid.

[0008] Working principle: During use, the positions of both sides of the fiberglass cloth are limited by the limiting clips. The braking cylinder is started, and the output end of the braking cylinder drives the adjusting piston plate to move upward, pushing the infiltration liquid upward until the fiberglass cloth is submerged. At this time, the servo motor is started, and the driving end of the servo motor drives one of the mounting shafts to drive the two transmission lead screws to perform forward and reverse rotations with a fixed period through the transmission belt, thereby realizing periodic changes in the distances at both ends of the fiberglass cloth, generating relative displacement with the infiltration liquid, and improving the infiltration effect. During the opening and closing of the fiberglass cloth, the negative pressure generated by the rotation of the negative pressure fan will drive the infiltration liquid to continuously wash the fiberglass cloth, further improving the infiltration effect. When the infiltration operation is completed, the braking cylinder is started, and the output end of the braking cylinder contracts, causing the infiltration liquid to separate from the fiberglass cloth. The servo motor continues to operate, continuously vibrating the fiberglass cloth to shake off the excess infiltration liquid, achieving the effect of recovering the excess infiltration liquid. At the same time, the negative pressure generated by the rotation of the negative pressure fan will accelerate the drying of the infiltration liquid and improve the production effect.

[0009] (III)Advantages The present invention provides a device for uniformly coating an infiltration liquid on a fiberglass cloth. It has the following advantages: 1. For this device for uniformly coating an infiltration liquid on a fiberglass cloth, the driving end of the servo motor drives one of the mounting shafts to drive the two transmission lead screws to perform forward and reverse rotations with a fixed period through the transmission belt, thereby realizing periodic changes in the distances at both ends of the fiberglass cloth, generating relative displacement with the infiltration liquid, and improving the infiltration effect. During the opening and closing of the fiberglass cloth, the negative pressure generated by the rotation of the negative pressure fan will drive the infiltration liquid to continuously wash the fiberglass cloth, further improving the infiltration effect.

[0010] 2. For this device for uniformly coating an infiltration liquid on a fiberglass cloth, when the infiltration operation is completed, the braking cylinder is started, and the output end of the braking cylinder contracts, causing the infiltration liquid to separate from the fiberglass cloth. The servo motor continues to operate, continuously vibrating the fiberglass cloth to shake off the excess infiltration liquid, achieving the effect of recovering the excess infiltration liquid. At the same time, the negative pressure generated by the rotation of the negative pressure fan will accelerate the drying of the infiltration liquid and improve the production effect.
