Problems solved by technology
[0002] In the current flat mesh + drum spunlace process popular at home and abroad, when the fiber web after flat mesh spunlace is transferred to the subsequent hydroentangling drum, the following situations may occur in the fiber web: 1. Because it is stuck on the flat mesh curtain and is not transferred to the subsequent hydroentanglement drum, the production is interrupted; 2. Although the fiber web is transferred to the drum, due to its relatively small strength, it is easy to cause major accidents drafting, resulting in shrinkage and burrs at the same time

Embodiment Construction
[0019] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.
[0020] Such as figure 1 As shown, the wet state fiber web active transfer drum device of the present invention comprises a drum liner 3, a vacuum box 4 is installed inside the drum liner 3, and a drum cover 1 is set on the outside of the drum liner 3; A seal 2 is installed on the inner tank 3, and a vacuum groove 5 is arranged on the drum inner tank 3. The width of the vacuum groove 5 is 8mm-30mm. The pressure of the vacuum box 4 is 0.05bar-0.5bar. The drum sleeve 1 consists of two parts: a cylinder body and a rebound layer. The barrel is perforated by thin steel plate, with an opening rate of 50%-90%; the outside of the barrel is covered with a rebound layer with micropores. The rebound layer is a stainless steel braided mesh layer or a nickel mesh layer, and the opening rate is 20-40%. An installa...

The invention relates to a drum device having a function of initiatively transferring wet fiber webs and belongs to the technical field of auxiliary devices for spunlace nonwoven production. The drum device having the function of initiatively transferring the wet fiber webs comprises a drum liner; a vacuum chamber is installed inside the drum linear; a drum sleeve is sleeved to the external of the drum linear; a sealing part is installed on the drum linear; a vacuum groove is formed in the drum linear. According to the drum device having the function of initiatively transferring the wet fiber webs, the drum linear is fixed and not rotates and an external motor drives the drum sleeve to rotate when the drum device operates; when the fiber webs which are fixed through front flat web spunlace heads pass the drum device along with a web curtain, the fiber webs can be initiatively transferred to the drum device due to a negative pressure adsorption function of the vacuum groove which is formed in a contact position of the fiber webs; the fiber webs are prevented from being adhered to the flat web curtain to be brought to be under a spunlaced machine and not operating according to a normal path and accordingly the problem that heads are difficult to generate during the spunlace strengthening process is solved.
Description
technical field [0001] The invention relates to a transfer drum device with the active transfer function of a wet fiber web, and belongs to the technical field of auxiliary devices for spunlace non-woven fabric production. Background technique [0002] In the current flat mesh + drum spunlace process popular at home and abroad, when the fiber web after flat mesh spunlace is transferred to the subsequent hydroentangling drum, the following situations may occur in the fiber web: 1. Because it is stuck on the flat mesh curtain and is not transferred to the subsequent hydroentanglement drum, the production is interrupted; 2. Although the fiber web is transferred to the drum, due to its relatively small strength, it is easy to cause major accidents At the same time, it causes shrinkage and burrs. Based on this, the present invention is proposed. Contents of the invention [0003] In order to solve the above-mentioned technical problems of the prior art, the object of the pres...
