Abstract
The invention relates to an anti-folding device on a spiral duct machine, which is characterized by comprising a fixed block (1), a connecting rod (2) and a pressure roller (5); one end of the connecting rod (2) is connected with the fixed block (1), and a connector (3) is welded on the other end of the connecting rod (2); a spring (4) is sleeved on the connecting rod (2) between the fixed block (1) and the connector (3); and the pressure roller (5) is arranged on the connector (3). The anti-folding device on the spiral duct machine can eliminate creases produced when an air duct is bent through the action of the pressure roller when the spiral duct is formed and the angle of the pressure roller can be adjusted according to the size of the air duct, so that the product quality is improved.
Description
Technical field
The present invention relates to a kind of folding preventing device.Be particularly related to the folding preventing device on a kind of stainless steel spiral duct forming machine.Belong to the tuber technical field.
Background technology
The band material that Spiral ducted unit is mainly used in web-like rolls into airduct cylindraceous.Spiral duct because of identical all areas of a circle greater than rectangular area, and do not have the dead angle, have that inner wall smooth is attractive in appearance, intensity is big, characteristics such as sealing height, construction install convenience are widely used in the industry such as purification, environmental protection of central air conditioner system, room air.
Spiral ducted unit is to rely on the spiral mould straight forming, and this molding mode is easy to generate folding line in the lower protection annealing material of the strength of materials when material is softer, influence product quality.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of folding preventing device is provided, prevent that Spiral ducted unit from folding line occurring when moulding, improve the quality of products.
The object of the present invention is achieved like this: the folding preventing device on a kind of Spiral ducted unit, described folding preventing device comprises fixed block, connecting rod and pressure roller, described fixed block is fixed on the perpendicular guide rail of adjustment diameter of Spiral ducted unit, described connecting rod one end inserts fixed block, and part is exposed to fixed block, the part that described connecting rod exposes fixed block is provided with spacing catch, the other end of described connecting rod is welded with joint, on the connecting rod between described fixed block and the joint, be with spring, described joint is provided with pressure roller, the angle of described pressure roller can be regulated automatically, is close to pipe on one side.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention can eliminate the folding line that airduct produces when crooked by the effect of pressure roller in the process of spiral duct moulding, and the angle of pressure roller can automatically adjust according to the size of airduct, thereby improves the quality of product.
Description of drawings
Fig. 1 is a structural representation of the present invention.
