PVC covered rollers
PVC-covered rolls visual gallery
The PVC-covered carrier roll is the roll that is applied to a PVC-based contact surface on the transport body. The whole PVC tube should not be mixed with the plastic body roll. In this section, the impact of the cover on the external size, contact with the product and maintenance arrangement is explained.
The extension and the end of the external diameter.
The outer diameter of the roll completed with the outer diameter of the metal body to be applied is different. The outer diameter of the existing and even working roll should be based on the finished outer diameter when the new is prepared, the bottom tube and the cover size should also be indicated. The difference in heights of the side-stop roles may cause the product base to press more on some roles. The covering is straight along the tube and the ends are part of the installation control that does not draw to the shade, head or transfer part.
PVC contact surface can be assessed in unwanted products to contact directly with the metal body. The surface of the product is important in the selection of drawing sensitivity, contact form and the need for cleaning. Surface protection target does not mean that the cover will not leave footprint in any circumstances. If the product has a slurry, sharp edge or dirt, the contact surface should also be assessed. The testing with the real sample to be carried is more explicit than making the selection of the cover only according to the material name.
The type of coating and the method of application may vary according to the material to be supplied. If the coating coating is used with heat, the application temperature and coating rate are determined according to the data of the material concerned; a single processing temperature for all PVC coating is not accepted. The prepared surface is checked to sit properly on the tube, not to crush and not to change the place during the work. The coating is treated along with the production method of how to protect the roll and other head parts from the processing during the replacement of the coating.
The holding behavior of the cover in a roulette is influenced by the flow of the product and the arrangement of the accumulation. The cover limits should be positioned correctly with the areas located in the cable channel or chain dent. The position of the transmission element may not change while increasing the entire diameter of the cover; therefore the existing shell and shell dimensions must be checked together. In maintenance, the traces of the crossing, relaxation, surface hardening and permanent compression are followed. It is also important that the type of cover and the finished diameter in the changed roulette are consistent.
Measurement and connection control for PVC-covered rolls
The total length of the mile is written separately with the tube length in measurement. The mile output may not be the same on both sides. The clear openness between the mile, the hole or channel and end connection is recorded. The size of the spare part is taken from the old sample and the size of a overwhelmed surface should not be considered as the production value. If there is a technical picture, it is shared with the photo, the interpretation of the measurement and the position of the pieces is clearly made according to each other.
| The body size | External diameter, tube length and meat thickness |
|---|---|
| Measurement of Mills | Diameters, total size and output in two ends |
| Connection | Sixth slot, mile end and assembly part |
| beds | Rulman code, cover seating and non-flat |
| Working knowledge | Product base, load distribution, speed and environment |
Point to be checked and monitored
PVC surface should be kept clean and unharmed. sharp parts, shrimp or drainage can overlap the cover. Cleaning material is selected in accordance with the type of cover. If the surface is relieved, flushed or drainated, the tube and cover is studied together. When a roll is changed, the control is made that there is no difference in diameter and height that has been completed with the neighboring rolls. The holding, flow and trace behavior of the product on the new surface can be observed by sample.
Frequently Asked Questions
Does PVC cover change the finished roll diameter?
Yes. The bottom tube diameter and the outer diameter after covering should be specified separately. It is important that the finished diameter in the side-working rolls is consistent.
Is the PVC cutting roll the same as the PVC tube body roll?
No. Covered roll has a PVC touch surface on the body; the plastic roll tube itself can be plastic.
Is there a single process temperature for PVC coating?
The method of application, the temperature and the compression rate are determined by the data of the relevant coating material; the same value for each product is not assumptive.
What information should be shared for the offer?
In a new transport line, the product's base size, the weight of the piece, the number of the product accumulated on the line and the working time are indicated. The photo from close to two ends with the general appearance of the existing piece in the replacement roll or head is shared. The order's full roll is clearly written that it is only cover, the rolled head or the cover renewal. The piece, the material preference and the existing technical picture can be evaluated together and the production scope can be more accurate determined. The production scope can be pre-evaluated according to the photo, but the production basic measures must also be verified.
