Oiling device

Abstract

The invention relates to an oiling device used for oiling outer walls of inflated casings. The oiling device comprises a plurality of oiling rollers, oiling material layers and a roller retaining device. Each oiling roller is in a waist drum shape with a thin middle and two thick ends and is capable of freely rotating around a center rotation axis, each oiling roller is provided with a hollow oil injection hole on the center rotation axis, one end of each oil injection hole is closed while the other end of each oil injection hole is communicated with an oil inlet pipe through a rotary connector, and a plurality of micropores are uniformly and peripherally distributed on the outer wall of each oiling roller and communicated with the corresponding oil injection hole. Each oiling material layer is made of an oil adsorbing and spreading material and coats the outer wall of the corresponding oiling roller. The roller retaining device is designed to be suitable for pressing the oiling rollers against outer walls of the inflated casings. By design of quantity and outer wall profiles of the oiling rollers, each casing corresponds to at least one oiling roller in any arc on the periphery of an outer wall cross section.

Description

technical field [0001] The invention relates to an oiling device, in particular to an oiling device for oiling the outer wall of an inflated casing tube. Background technique [0002] In some occasions, the tubular film needs to be evenly coated with lubricating oil or other liquids on the outer wall, such as the production process of artificial casings. The outer wall of the casing is evenly covered with a thin layer of oil. On the one hand, it is convenient for the folding device to fold the casing when it is folded. On the other hand, it is easy to stretch and pull the folded casing during enema, without sticking together layer by layer. [0003] The original technology has the oil spray method and the oil box smear method. The oil mist sprays several spray heads surrounding the casing to spray fine oil mist to the casing. The disadvantage is that part of the sprayed oil mist diffuses in the air. If it is not sucked and discharged, it will affect the environment. A venti...

Problems solved by technology

Greasing box smearing is usually an oiling box connected to the oil pipe with openings at both ends, passing the inflated tubular casing through the middle, and touching the casing through the annular sponge or oil-absorbing cotton ring on the inner wall of the oiling box to smear the oil On the outer wall of the casing, the shortcoming needs to be replaced with different ring sponges or oil-absorbing cotton rings on the inner wall of the grease box according to the different calibers of the casings. The inner hole of the ring sponge and the caliber of the casing must match. Inflated casings will cause uneven oil film on the surface of casings. If there is too much contact, it will generate a lot of friction, which will affect the smooth feeding of the next shrinking process.
