1, horse nail machine planting brush: the most traditional brush making process, after punching holes on the surface of the brush roll or brush plate, use the horse nail planting machine to implant the brush hairs in a bunch of bunches into the brush roll or brush plate, the brush products made by this process are most widely used, one is the lower cost, the brush is made into a consumable, the cost is a must to consider. However, the brush roll made of horse nail planting hair has several shortcomings: First, the density is not enough, because there must be a certain spacing between each hole of the perforated planting hair, there is a spacing can not be planted out of high-density effect, in some special industries require high-density brush roll to work can not be used in this kind of horse nail machine planting hair of the brush roll; second is the bonding of the wire is not enough fastness, the so-called horse nail planting hair is the use of iron wire through a convex groove is pressed into the "U" type. The so-called studding method is to use iron wire through a convex groove is pressed into a "U" buckle, used to buckle the brush wire implanted in the punched holes, "U" buckle in the holes after crossing deep into the holes stuck, so that the combination of brush wire in the roller shaft, but the tension is limited, if in some special industries require high speed operation of the brush roller This process is not ideal for the production of brush rolls in some special industries that require high speed operation.
2, spring brush: spring brush process made of brush rollers to solve the problem of high density, fastness and other issues, the manufacture of the first after the strip brush equipment will be bristles by a steel wire pressed into the aluminum or stainless steel belt made of brush, and then wound in the roller shaft, the use of kettle weld the two ends, in some special industrial production, but also need to be made into a spring brush with a certain gap because of the need to take into account the special effects of dust and so on.
3, the pressure piece brush: is the brush wire tightly arranged together, and then put into a specific mold with a piece of steel through the stamping machine made of a piece of brush wheel, in the manufacture of brush rollers can be more than one piece of brush wheel strung together fixed in the roller shaft, the brush made of this process can be the highest density of brush wire, but the disadvantage is that the cost of the higher, and the efficiency of the manufacture of the slow.
4, injection molding brush: the brush wire is arranged into a special mold, and then the use of injection molding will be fused together with the brush wire and brush plate to form a one-piece, the advantages of this process lies in the high combining power of the bristles because it has been fused together with the brush plate, sanitation trucks, sweeping brushes are made with this process.
5, twisted wire brush: is the brush evenly discharged in the middle of two 0.5-2mm wire, one end of the clamping, the other end of the motor through the output force, the wire will be twisted molding, by the shearer trimming to standard size, hydraulic parts pipeline brushes, ball head brushes are made of this process.
6, strip brush: mainly used in the escalator industry, China's GB16899-1997 "escalators and moving walks manufacturing and installation safety standards" clearly stipulated in the "plus appropriate anti-clamping devices" to ensure passenger safety. The Hong Kong regional standard in the 1. 1. 5. 5 provisions: "in the escalator on the right and left end of the step side and the apron board with anti-clamping device can reduce the risk of accidents between ......", and provides for the anti-clamping device of the basic dimensions and the location of the apron board. The best installation position of the brush anti-pinch device is about 5mm from the front of the comb plate at the entrance and exit of the escalator ladder, installed on both sides of the apron board, covering the gap between the running steps and the apron board, and its installation height should be about 50mm above the steps at the entrance and exit of the escalator. Escalator brush: the brush hair extends long generally in 50mm-52mm or so, the thickness of the brush strip in 5mm×5mm, 6mm×6mm or 7mm×7mm is appropriate; brush brush wire material adopts soft black nylon wire (special requirements of flame retardant treatment of the nylon brush wire) is good, does not hurt clothes, but also have a certain degree of elasticity in the passenger's shoes touching the brush should be able to recover. Brush should be able to recover. Brush anti-pinch device consists of two parts, the base and brush, the base must be a good unit structure, does not allow the possibility of danger, and can be easily removed. Its surface should be smooth, no sharp edges, and firm and will not break. Brush bristles material using soft nylon wire (special requirements of flame retardant treatment of nylon bristles) is better, does not hurt clothing, but also to have a certain degree of hardness, in the passenger's shoes touch the brush should be able to recover. Equipped with brush device escalator, so that passengers appear escalator gap on both sides of the clip accident is almost zero, visible escalator brush plays a role is obvious.
