Description

Technical Field

[0001] The utility model relates to the technical field of papermaking equipment, in particular to a papermaking forming wire. Background Art

[0002] In the papermaking process, pulp is turned into paper through a series of technological steps and equipment, and the papermaking machine is one of the main equipment. The pulp is sent to the headbox and sprayed onto the forming wire surface through the headbox. The forming wire is an important component on the papermaking machine and is a device for paper sheet forming and dewatering on the papermaking machine. It dehydrates the pulp suspension from the headbox and transports the paper web to the subsequent sections. Among them, the long wire forming and drying is the most common method. In the papermaking process, the pulp is transported onto the forming wire. During the process of running with the wire, the water and other liquids in the pulp are filtered, and the raw material fibers in the pulp are separated from the water medium to form a wet paper web on the forming wire, then dehydrated by pressing, and finally dried into paper. Currently, the common papermaking forming wire has the following deficiencies: the wear resistance of the wire edge of the forming wire is not high and it is easy to be damaged during use; moreover, the dewatering efficiency of the forming wire during use is relatively low, and usually, the way of increasing the length is needed to improve the dewatering rate, which increases the papermaking cost. Summary of the Utility Model

[0003] The purpose of this application is to provide a papermaking forming wire, aiming to solve the problems in the prior art.

[0004] An embodiment of this application provides a papermaking forming wire, including a synthetic wire; the synthetic wire includes a top layer, a middle layer, and a bottom layer; both the top layer and the bottom layer are carbon fiber wires; the middle layer is a water absorption layer; protection wires are arranged on both left and right sides of the synthetic wire; the connection wire is in a U-shaped groove; connection buckles are arranged on the inner wall of the top of the protection wire, and corresponding card slots are arranged at the bottom; the middle layer is formed by multiple warp and weft threads intertwined with each other; the weft threads are polyester steel wires; the warp threads are high moisture absorption fiber threads.

[0005] Further, the carbon fiber wire is woven from carbon fiber filaments.

[0006] Further, the joint between the protection wire and the synthetic wire is filled with high-temperature resistant glue.

[0007] Further, both the top layer and the bottom layer of the synthetic wire are connected to the middle layer through weft threads in the weft direction.

[0008] Further, the connection buckle is made of flexible polyester fiber.

[0009] The beneficial effect of the utility model is that a water absorption layer is added in the middle of the forming wire to increase the strength and wear resistance of the whole wire body. The water absorption layer is woven from polyester steel wires and high moisture absorption fiber threads, which not only retains the stability of the steel wires but also adds water absorption, improving the dewatering rate of the whole forming wire.
