Description

Technical Field

[0001] The utility model relates to the technical field of printing and manufacturing equipment, in particular to a large wrap angle traction device which is convenient to adjust. Background Technique

[0002] Decorative paper is an essential raw material in many building materials products, such as the low-pressure boards and high-pressure boards used in furniture and cabinets, as well as fireproof boards, floors, etc. In the product structure, decorative paper mainly plays a decorative role in providing pattern designs and a covering role in preventing the seepage of the underlying glue solution. This layer requires the paper to have good covering power, impregnation property and printing performance. Decorative paper requires a smooth surface. During the winding process of decorative paper, if the decorative paper is not flat, creases and damages will occur to the decorative paper, affecting the winding effect. Therefore, it is necessary to pull the decorative paper flat for winding. Decorative paper is relatively thin and is easily damaged under the influence of tensile force. Therefore, it is necessary to improve the traction device. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] All the features disclosed in this specification, or all the steps in any method or process disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0018] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless specifically stated otherwise, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated otherwise, each feature is only an example of a series of equivalent or similar features.

[0019] Such as Figures 1-3As shown in the figure, an adjustable large wrap angle traction device includes a mounting plate 1 and a stretching roller 2. There are two mounting plates 1, and the stretching roller 2 is arranged between the two mounting plates 1. A first limiting roller 3 and a second limiting roller 4 are respectively arranged above and below one side of the stretching roller 2, and a third limiting roller 5 is arranged below the other side of the stretching roller 2. Fixed rods 6 are arranged at both ends of the first limiting roller 3, the second limiting roller 4, and the third limiting roller 5. A limiting block 7 is fixedly installed on the fixed rod 6. A plurality of long slots 8 are opened on the mounting plate 1, and the limiting block 7 is arranged in the long slot 8. A plurality of adjusting slots 9 are arranged on one side of the long slot 8 and communicate with the long slot 8. The bottom edge of the adjusting slot 9 is an arc structure, and a rubber pad 10 is arranged on the bottom edge of the adjusting slot 9.

[0020] Rotating plates 11 are arranged on both of the two mounting plates 1. A rotating node 12 is arranged at the upper end of the rotating plate 11 and is installed on the mounting plate 1 through the rotating node 12. A resisting roller 13 is installed between the two rotating plates 11. A soft cushion layer is coated on the outer surface of the resisting roller 13. Telescopic cylinders 14 are connected to the lower ends of the two rotating plates 11, and the telescopic cylinders 14 are arranged on the mounting plate 1. A limiting nut 15 is arranged on one side of each of the two rotating plates 11, and the limiting nut 15 is fixedly installed on the mounting plate 1. A limiting bolt 16 is arranged in the limiting nut 15; Bearings are arranged at the connection positions between the two ends of the stretching roller 2 and the mounting plate 1 and are installed through the bearings; Bearings are arranged at the connection positions between the first limiting roller 3, the second limiting roller 4, and the third limiting roller 5 and the fixed rod 6 and are installed through the bearings; The width of the limiting block 7 is greater than the sum of the width of the long slot 8 and the length of the adjusting slot 9; The diameter of the fixed rod 6 is smaller than the width of the adjusting slot 9; A rotating shaft is arranged at the connection position between the resisting roller 13 and the rotating plate 11 and is connected through the rotating shaft; A rotating shaft is arranged at the top end of the telescopic cylinder 14 and is connected to the rotating plate 11 through the rotating shaft.

[0021] During use, the front end of the decorative paper is successively wound around the first limiting roller 3, the stretching roller 2, the second limiting roller 4, and the third limiting roller 5, and then the front end of the decorative paper is connected to the subsequent device for printing or winding. After that, the telescopic cylinder 14 is controlled to pull the rotating plate 11 to rotate around the rotating node 12, so that the abutting roller 13 abuts against the stretching roller 2, and then the motor is used to pull and move the decorative paper for transportation; if it is necessary to adjust the abutting degree of the abutting roller 13, the rotation angle of the rotating plate 11 can be adjusted by adjusting the screwing-out length of the limit bolt 16 in the limit nut 15, so as to adjust the pressing degree between the abutting roller 13 and the stretching roller 2; if it is necessary to adjust the wrap angle of the decorative paper on the stretching roller 2, the fixing rod 6 clamped in the adjustment groove 9 can be adjusted to the required position and then moved to the corresponding adjustment groove 9, so as to adjust the upper and lower positions of the first limiting roller 3, the second limiting roller 4, and the third limiting roller 5, and thus adjust the wrap angle of the decorative paper on the stretching roller 2.

[0022] The design of this design scheme is ingenious. The setting of the first limiting roller 3 and the second limiting roller 4 enables the decorative paper to form a large wrap angle on the stretching roller 2, and the stress area of the decorative paper is larger, making the thinner decorative paper stretched flat and not easily damaged or broken under the influence of the tensile force; the position of the fixing rod 6 can be adjusted, and the wrapping angle of the decorative paper on the stretching roller 2 can be adjusted according to needs; the arc-shaped structure and the rubber pad 10 below the adjustment groove 9 can limit the fixing rod 6 to prevent the fixing rod 6 from displacing; the soft cushion layer covered on the outer surface of the abutting roller 13 can reduce the damage phenomenon caused by the pressure influence on the decorative paper; the limit bolt 16 can adjust the protruding length, so as to adjust the pressing degree between the abutting roller 13 and the stretching roller 2, and the use is diversified.

[0023] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
