Randy McBride with Western Belting Ltd, has revolutionized conveyor belt cleaners with the newly developed and patented Just-In Scraper. With over 25 years of experience servicing conveyor systems, Randy McBride has developed an efficient and extremely effective conveyor belt cleaner which meets and exceeds our customer’s expectations.
The Just-In Scraper comes ready for install with brackets and stickers that identify the front.
The blades are compressed , banded and the bands are easily removed once installed.
Having the scraper compressed during installation saves time.
The purpose of a conveyor belt cleaner is to prevent residue build up on the surface of the conveyor belt. When residue builds up on a belt it can cause damage to the conveyor belt and/or conveyor structure resulting in costly maintenance and repairs. This carry back debris can also be transferred to the ground or waterways under the conveyor causing environmental damage and costly clean up or possible fines. The Just-In Scraper greatly reduces production down time and improves the bottom line.
The Just-In Scraper’s core is a high pressure air bladder with no moving mechanical parts…just a cushion of air…moving the conveyor belt cleaning blade up, down and in tangent with the moving belt. The Just-In Scraper distributes constant pressure across the entire width of the conveyor belt, and its effectiveness is not limited by any irregularities due to conveyor belt surface wear, pulley surfaces covered in slide lag, mechanical belt fasteners, reversing conveyors, and liquid removal (such as water). Pressure to the air bladder is maintained by attaching a regulator supplied from an external air source. Placing the regulator in a remote location away from the Just-In Scraper, allows for an easy and safe adjustment of pressure to the cleaning blade.
The revolutionary design of the Just-In Scraper can clean conveyor belts widths of 12” and wider more effectively than anything else out there on the market
Most commonly asked questions.
How does the scraper help save the environment?
By directing the material off the face of the belt in a efficient manner, helps protect water ways and contaminants that could seep in the ground.
What would be the advantage of controlling cleaning pressure from a distance?
Safety as well as convenience of control.
Having the ability to decrease and increase pressure from a control both with the other operation systems.
Where do I put the scraper on the system?
Anywhere along the return side, preferably a hold down roll keeping the under side stable so that the scraper can maintain even pressure.
Can it act as a primary scraper system?
Yes, As long as the scraper maintains a 7-10 degree angle carrying back position and falls under the ark of product flow and in some cases two can be placed on the head pulley with great results.
Note: If the scraper makes a chatter sound the angle carrying back may not be enough.
How accurate does the install with the calculations of square and level have to be?
The scraper runs on an air cushion and self levels on the face of the belt and pulley.
How much air pressure should be used?
It is recommended to adjust the pressure at a safe distance and as the belt is in operation.
Start low and work your way up. Over pressure can decrease scraper life.
On the 18” and 24” wide belts 3 Lbs to 10 Lbs depending on the product that’s running.
( Customer preference)
On the 30” too 96” wide belts 9 Lbs to 12 Lbs depending on the product that’s running.
( Customer preference)
Why don’t you use a urethane scraper blade?
Most urethane's, as they become softer become weaker and tend to tear under the drag.
The scraper blade that comes with the product has three layers of rubber, it can flex with the air movement. As the scraper rubber wears in the middle, the pressure regulates the contact with the belt at all times.
Changing the scraper blade.
Price of replacement blades can be an issue for customers, using heavy conveyor belt as a replacement blade by using the old blade as a template for the hole punching.
Note: A bead of silicone between the red outer cover and the scraper blade must be applied during blade change.
Note: The scraper material must not be of a segmented hard material. Uneven wear can result in possibility damaging the scraper components.
Why do you need the red material?
The Red portion of the scraper is attached to the scraper blade so it will move with the cleaning blade and because the face of the belt is seldom perfectly flat it vibrates and allows material to slide off.
Can I make my own mounting system?
The mounting brackets are just a suggested means of mounting the scraper. To get the scraper into some areas the customer may have to cut the mounting flanges on the scraper and can mount it in a different way.
Note: Welding to the actual body of the scraper or heating it with a torch is not recommended and can cause damage to the inner workings.
