When shopping in shopping malls, when we take the escalator, careful friends will notice that there is a row of brushes on both sides of the escalator steps. At this time, it is inevitable that some passengers will be curious: what are these escalator brushes used for, and what is the meaning of their existence? So, what are the brushes on both sides of the escalator steps in the mall used for? In fact, whether it is in a shopping mall or a supermarket, or even the subway escalator we take in our daily travel, the brushes installed in a row next to the escalator steps are used to prevent pinching, that is, to prevent pinching. The real name of this anti-pinch brush is "Apron Plate Anti-Pinch Device". The main purpose of setting this brush for escalator safety is to remind us that it is dangerous here, so don't approach it. Because there will be a certain gap between the steps of the escalator, between the steps and the upper and lower end stations, and the surrounding apron boards, to be precise, the gap is not more than 4 mm. Although the gap is not greater than 4 mm, such a small gap may cause clothes or shoelaces to be caught and caught, resulting in escalator safety accidents. In addition, my country has stated in the "Safety Specifications for the Manufacture and Installation of Escalators and Moving Walks (GB16899-2011) that the brush on the escalator is mainly used to prevent pinching. The escalator is equipped with escalator safety brushes in shopping malls mainly to prevent accidents when passengers enter and exit the escalator. Therefore, it is necessary to install safety brushes on escalators in shopping malls to ensure the safety of passengers.

The brushes of the escalator are usually installed on both sides of the lower part of the escalator to prevent the safety hazard caused by the entanglement of items such as shoelaces or clothes in the gap between the steps of the escalator and the side panels of the escalator. It is common in shopping malls, supermarkets or subway entrances and exits on the escalator, play the role of anti-pinch. Generally, this brush is set up mainly to remind us that there is danger here, so don't approach it. In addition, the brush on the escalator has another function, which is to prevent some small parts such as coins, mobile phones, keys, etc. from falling into or getting stuck in the gap, thus affecting the normal operation of the machine. So, when you see this, you should know: where is the brush of the escalator and what is the main function of the brush of the escalator. Here, it is worth mentioning that when taking an escalator, you must pay attention to the three common escalator danger points as follows: 1. The gap between the apron board and the steps The dangerous point of the escalator is the place where the brush is provided as a protective device, that is, the gap between the escalator apron and the steps. Although the gap is very small, no more than 4mm, it is very dangerous for children who are active and have little safety awareness. 2. The junction between the steps and the ground If the gap between the steps of the escalator and the ground is not properly maintained, it is likely to become larger. If you are not careful, this place is prone to escalator safety accidents. 3. Triangular area The so-called "triangular area" refers to the triangular area formed by the handrail and the upper floor. This is a dangerous "thunder point" of the escalator. When the escalator goes up to the triangular area, if the child is active or mischievous, if the child sticks his hand or head out of the handrail, his head may be caught, or even There will be bigger safety accidents while taking the elevator.

Industrial brushes are used for polishing, deburring, grinding and other purposes. There are many problems that need to be paid attention to in the use of industrial brushes, and the precautions should be popularized for users. Precautions for the use of industrial brushes: Industrial brushes sometimes have quality problems due to the wear of the shaft, the bending of the brush filaments, the abuse of the operator or improper use, etc. Try not to use damaged or malfunctioning brushes. Because this may lead to aggravated brush damage and human injury, the brush should be replaced as soon as possible, and related operations should be improved to avoid unsafe production. When using industrial brushes, avoid excessive force, otherwise the brush filaments will be bent and deformed, heat will accumulate after friction, the brush will be damaged and dull, and the service life will be greatly reduced. If you think the cutting power of the brush is not enough, it is recommended to use a sharper brush or increase the speed of the brush appropriately, instead of using too much force.

Industrial brush deburring is a process that removes burrs on the surface of the workpiece by using the brush disc to rotate and instantly rub against the workpiece to generate cutting force. For workpieces with uneven surface within 100mm, the orifice, inner hole, step edge, surroundings and surface of the workpiece can be deburred by using the brush deburring machine. According to the different materials of the workpiece, choose different brush discs to deburr. Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. It has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically remain unchanged even at a temperature of 500℃. It still has high hardness at 1000℃. Therefore, the corner passivation processing of cemented carbide requires the use of Sweden BP-MX corner passivation polishing brush deburring machine. And cutting tool polishing, edge passivation, deburring processing. By changing the workbench or clamping method, it can not only process flat disk workpieces, but also passivate, polish and deburr the corners of shaft parts. Flat or slightly concave-convex workpieces are evenly processed by abrasive brushes on a planetary light extraction table. Through the rotary motion of the worktable, the workpiece carrier and the brush, the corners of the workpiece in all directions are uniformly passivated and deburred. In this process, the upper surface of the workpiece is also polished simultaneously. Modular design allows special combinations to suit customer's application; compound interchangeable table for maximum flexibility; dry or wet processing possible; automatic compensation for brush roller wear leads to consistency of results; can produce various edge shapes; fully enclosed working environment; touch-screen simple operation interface.
