Description

Manual tensioning roller applied to color-coated sheet production line

technical field

The utility model can belong to the field of mechanical (steel plate) processing, and relates to a color-coated production line, in particular to a manual tension roller applied to a color-coated plate production line.

Background technique

At present, in the color-coating production line, the color-coated board generally needs to be transported over a long distance for the next step of processing. However, because there is no tensioning device, the color-coated board is too loose, and it is easy to sag due to gravity, causing up and down shaking, and it is easy to be scratched during the shaking process, which affects product quality.

By searching, no disclosed technical solutions for solving the technical problems of the utility model have been found yet.

Contents of the invention

The purpose of this utility model is to provide a manual tensioning roller applied to the color-coated plate production line to alleviate the problem of no tension when the color-coated plate passes through a long distance, and to solve the problem of sagging, shaking, and scratching of the strip during operation. The problem.

The technical scheme that the utility model adopts is:

A manual tension roller used in a color-coated sheet production line, consisting of a front rubber roller and its front bearing seat, a rear rubber roller and its rear bearing seat, a front lifting mechanism, a rear lifting mechanism, a front bracket and a rear bracket, and the front bracket Two front bearing blocks at both ends of the front rubber roller are installed on the upper ends of both sides of the front rubber roller, and the front lifting mechanism is fixed on the front bracket below the two front bearing seats; the rear lifting mechanism is fixed on the upper end of the rear bracket behind the front rubber roller. The rear rubber roller and the rear bearing seat are installed in the middle part of the support, and the axes of the front rubber roller and the rear rubber roller are staggered.

Moreover, the structure of the front elevating mechanism is the same as that of the rear elevating mechanism, and they are all composed of a hand crank, a worm drive, a lead screw, a screw nut and a linear guide rail, and the linear guide rail is fixed on the front bracket or the rear bracket. The upper end of the guide rail is fixed with the front bearing seat or the rear bearing seat, and the screw nut is fixed on the front bearing seat or the rear bearing seat. The screw nut is engaged with the lead screw, and the lower end of the lead screw is coaxially installed with the worm wheel of the worm gear drive. The hand crank is connected with the worm of the worm gear drive.

The advantages and positive effects that the utility model adopts are:

1. The tension roller is realized by two rubber rollers and a set of adjustment device. The two rubber rollers are installed in front and rear dislocations, and the upper and lower positions are adjusted by the adjustment device. The color-coated plate passes between the two rubber rollers. Use the adjusting device to adjust the up and down position of the rollers to make it an S-shaped angle, squeeze the color-coated board tightly, and increase the tension of the color-coated board in this section, thus avoiding the product from sagging and swinging up and down.

2. The tension roller has a simple structure, scientific and reasonable design, and low cost, which can effectively avoid the problems that the color-coated board in the color-coated board production line is too loose and easily sags due to gravity, shakes up and down, and is easy to scratch during the shaking process , effectively improving product quality.

Detailed ways:

The utility model is described in further detail below through specific examples, the following examples are only descriptive, not limiting, and cannot limit the protection scope of the utility model with this.

A manual tension roller applied to a color-coated sheet production line, consisting of a front rubber roller 16, a front bearing seat 15, a front lifting mechanism, a front support 9, a rear rubber roller 7, a rear bearing seat 6, a rear lifting mechanism, and a rear support 8 Composition, two front bearing blocks at the two ends of the front rubber roller are installed on the upper ends of both sides of the front bracket, and the front lifting mechanism is fixed on the front bracket below the two front bearing seats. Each front lifting mechanism is composed of a hand crank 10, a worm gear Worm drive 11, lead screw 12, screw nut 14 and linear guide rail 13 constitute, linear guide rail is fixed on the front bracket, the front bearing seat of the front rubber roller is fixed on the upper end of the linear guide rail and the front bearing seat of the front rubber roller, and is fixed on the lower end of the front bearing seat. Install the screw nut, the screw nut meshes with the screw, the lower end of the screw is coaxially installed with the worm gear of the worm gear drive, and the hand crank is connected with the worm screw of the worm gear drive, so that the worm drives the worm gear when the hand crank rotates Rotate, the worm wheel drives the lead screw to rotate, and the lead screw meshes to drive the screw nut to move up and down, thereby driving the up and down displacement adjustment of the front bearing seat and the front rubber roller.

The rear lifting mechanism is fixed on the upper end of the rear bracket behind the front rubber roller. The rear rubber roller and its rear bearing seat are installed in the middle of the rear bracket. The axes of the rear rubber roller and the front rubber roller are staggered. The rubber rollers form an S shape. The structure and function of the rear lifting mechanism are exactly the same as those of the front lifting mechanism. It is made of hand crank 2, worm gear drive 1, leading screw 3, linear guide 5, screw nut 4, and its specific connection relationship is no longer repeated.

The working principle of the utility model is:

The linear guide rail is used as the executive mechanism for the front and rear rubber rollers to move up and down. The linear guide rail is fixed on the bracket. The bearing of the linear guide rail is connected with the bearing seat of the rubber roller with screws, and the nut of the bearing seat is connected. The hand crank is driven by a worm gear drive. When the lead screw rotates, it engages with the driving screw nut to realize the transformation from rotation to linear displacement; the bearing seat and linear guide rail linear displacement, so as to achieve the purpose of adjusting the up and down movement of the front and rear tension rollers. As shown in the figure, when the front and rear rubber rollers are misaligned to form an S shape, the color-coated plate will be squeezed tightly by the front and rear rubber rollers to increase the tension.
