Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber belt production, in particular to a pressing mechanism for a glass fiber belt coiling machine. Background Technique

[0002] The glass fiber belt is made of high-temperature resistant and high-strength glass fiber through special processes, and has the characteristics of high temperature resistance, heat preservation and insulation, insulation, fire prevention and flame retardance, corrosion resistance, aging resistance, weather resistance, high strength, smooth appearance, etc. It is mainly divided into glass fiber heat preservation and heat insulation belts, silicone rubber glass fiber protection and heat insulation belts, glass fiber radiation protection and heat insulation belts, etc. During the production of glass fiber belts, a coiling machine is required to coil the finished belt into a cake shape.

[0003] When an operator uses the coiling machine to coil the glass fiber belt, a relevant pressing mechanism is often used to prevent the glass fiber belt from running off and shifting during the coiling process, resulting in an unattractive coiled glass fiber belt. The existing pressing mechanism generally uses a stainless steel pressing plate to squeeze one side of the glass fiber belt. Since the extrusion is not mechanized enough, the glass fiber belt is not evenly stressed, often resulting in the glass fiber belt being damaged.

[0004] As disclosed in a pressing mechanism for a coiling machine with the publication number CN220906684U, by setting a lifting plate, a pressing block, a second motor, a rotating rod and a rotating plate, when the operator starts the second motor, the operation of the second motor will cause the rotating rod to drive the rotating plate to rotate. At this time, the rotating plate will rotate and squeeze the pressing block, causing the pressing block to move downward, and the pressing block will drive the fixing plate to move downward at the same time. At this time, the fixing plate will cause the lifting plate to move downward smoothly under the limiting action of the limiting plate. At this time, the lifting plate will smoothly squeeze the glass fiber belt, and there will be no phenomenon of the glass fiber belt shifting and running off.

[0005] However, during the use of this device, the glass fiber belt cannot be tensioned, resulting in the coiled glass fiber belt being not compact, causing the pressed glass fiber belt to be loose and affecting the coiling quality of the glass fiber belt.

[0006] Therefore, we urgently need to provide a pressing mechanism for a glass fiber belt coiling machine. Content of the Utility Model

[0007] The purpose of the utility model is to provide a pressing mechanism for a glass fiber belt coiling machine to solve the problem that the glass fiber belt cannot be tensioned during use, resulting in the coiled glass fiber belt being not compact, causing the pressed glass fiber belt to be loose and affecting the coiling quality of the glass fiber belt as mentioned in the above background technique.
