1、 Product Introduction

A single spiral, single group iron sheet is wound into a brush. (Usually using a brush)

Two sets of double helix iron plates are intertwined to form a brush. (New product)

１，３，５，７，９. .. Is white, 2, 4, 6, 8, 10 .. Is black, with two sets of intertwined brushes.

(Actually made in full white)

2、 Introduction to the advantages and disadvantages of single spiral and double spiral brushes

1. Normally used brushes are single helix, but the bristles will condense together when they come into contact with water, and regardless of whether they rotate tightly

There will definitely be gaps.

A - The gaps between bristles, regardless of how dense they appear before use, will condense and create gaps when exposed to water during use.

B - No matter how tight the iron sheets are, there will always be gaps between them.

2. The double helix brush solves the gap problem mentioned above.

C - The gap between bristles. Regardless of whether the bristles aggregate with water before or after use, there will always be contact surfaces between the bristles

Fill the gaps.

D - Gap between iron sheets

The gap between iron sheets can be filled by the slope.

3. The contact surface of a single spiral brush rotating once is 1 point, but the contact surface of a double spiral brush rotating once is 2 points, doubling the effect.

4. The inclination angle of the double helix brush is twice that of the single helix, so the contact and peeling force will increase.

3、 Introduction to bristle manufacturing forms.

Spiral roller

1. Brush fixing method: The bristles are planted into a continuous U-shaped iron plate, and then processed and clamped to fix the bristles.

2. Manufacturing of winding brush drum:

A. Wrap the fixed plate with implanted bristles continuously around the axis, and then fix it.

The fixing method between the fixing plate and the axis of the B implanted bristles:

a. Use special fixing fixtures to secure the axis with screws.

b. Fix to the axis using welding.

Hair planting wheel brush

1. Hair planting arrangement:

A Thousand Bird Hair Planting Method: Planting pores arranged in a staggered manner is currently the most commonly used hair planting method for cleaning glass.

B Chessboard style hair planting method: planting pores arranged in a staggered manner.

C single spiral hair planting method: numerical hair planting method based on degree. (Rotate from one side to the other, can be left to right or right to left)

Double helix hair planting method: Spiral planting method from the center outwards.

2. Hair planting aperture: Currently, commonly used hair planting apertures include O2, O3, O4, O5, O7 (depending on the product used)

3. Material of hair planting layer:

The commonly used materials for the hair planting layer are PVC, PP, and PE

4. Calculation of brush roller diameter

A total outer diameter of bristles=axis diameter (thickness of hair planting layer and height of hair planting) X 2

The total outer diameter tolerance of bristles B is taken as ± 0.05m/m, and the diameter tolerance of the planting layer is taken as ± 0.1m/m
