Description

Technical Field

[0001] The invention belongs to the technical field of scanners, and in particular relates to a scanner which can move on the surface of a plane material by itself to extract patterns on the surface of the plane material for use. Background Art

[0002] Due to the limited size of scanners currently used in offices, in some industries such as the ceramic and other building materials industries, printing is often used to print patterns or decorative textures onto the surface of tiles or decorative materials. These patterns or decorative textures sometimes need to be completely scanned and extracted from other similar products before printing. When the size of decorative materials such as tiles is large, it is far beyond the size of existing scanners. It is difficult to use existing scanners to scan and extract the complete patterns or decorative textures on the surface of large-size tiles and other decorative materials. This brings certain troubles to the extraction of production materials in the industry. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention aims to provide a scanner that can walk on the surface of a planar material to scan and extract its surface patterns, making the scanning and extraction of surface patterns of large-sized planar materials simpler and more convenient.

[0004] To achieve the above object, the present invention adopts the following technical solution:

[0005] A scanner that can walk on the surface of a flat material to scan and extract its surface pattern comprises a scanning head. The composition of the scanning head is the same as that of an existing scanner. Rollers are installed on the front and rear of the scanning head respectively through axles. The two ends of the axles are connected by a transmission belt. One end of one of the axles is connected to the drive motor through a pulley assembly. A reference white bar is placed on the lower belt strip of the transmission belt across the scanning window of the scanning head. A metal sheet is provided on one end of the reference white bar, and the metal sheet corresponds to a proximity switch. White bar limit blocks are provided on both sides of the scanning head at the sides of the reference white bar. The drive motor and the proximity switch are respectively electrically connected to the circuit main board built into the scanning head. Initially, the metal sheet corresponds to the proximity switch and works when the power is turned on. The scanning is started, the driving motor works and drives the roller to move. The movement of the roller will drive the transmission belt to rotate. The reference white strip placed on the transmission belt will move with the transmission belt to the white strip limit block on the side of the wheel shaft that is not connected to the pulley assembly and then stop, completing the scanning reference verification. At this time, the metal sheet is disengaged from the proximity switch, and the driving motor reverses to drive the roller to move on the surface of large-size tiles and other decorative materials to scan the surface patterns of the materials. It walks on the surface of flat materials to scan and extract their surface patterns, making the scanning and extraction of surface patterns of large-size flat materials simpler and more convenient. After the scanning is completed, the driving motor reverses again instantly, and the transmission belt reverses instantly, causing the reference white strip to move with the transmission belt and be blocked by the white strip limit block on the other side, and then reset to correspond to the proximity switch again.

[0006] Preferably, the pulley assembly includes a driving pulley, a first driven pulley, a second driven pulley and a third driven pulley, the driving motor is mounted on the housing of the scanning head through a mounting frame, the driving pulley is mounted on the motor shaft of the driving motor, the first driven pulley is mounted on the mounting frame and is connected to the driving pulley through a first belt, the second driven pulley is coaxially connected to the first driven pulley, and the third driven pulley is mounted on the wheel shaft and is connected to the second driven pulley through a second belt.

[0007] Furthermore, a tensioning pulley for adjusting the tension of the first belt is installed on the mounting frame between the driving pulley and the first driven pulley.

[0008] Preferably, the proximity switch is located above the metal sheet, and the proximity switch is fixed on the housing of the drive motor.

[0009] Preferably, the transmission belt is connected to the wheel axle through a synchronous pulley, and seat bearings are fixedly arranged at the front and rear of the scanning head, and the wheel axle is installed on the seat bearings.

[0010] The present invention has the following beneficial effects:

[0011] The invention is a scanner that can walk on the surface of a plane material, scan and extract its surface patterns. The driving motor can drive the roller to walk on the surface of large-size ceramic tiles and other decorative materials to scan the surface patterns of the materials. When the scanning is initially started, the roller will drive the transmission belt to rotate while walking. The reference white strip placed on the transmission belt will move with the transmission belt to the white strip limit block and then stop, thus completing the scanning reference verification. The invention has the advantages of being able to walk on the surface of a plane material, scan and extract its surface patterns, and making the scanning and extraction of the surface patterns of large-size plane materials simpler and more convenient.

The transmission belt 4 is preferably connected to the axle 2 through a synchronous pulley 42, and one end of one axle 2 is connected to the driving motor 6 through a pulley assembly 5. A reference white strip 7 is placed on the lower strip 41 of the transmission belt 4 across the scanning window of the scanning head 1. A metal sheet 8 is provided on one end of the reference white strip 7. The metal sheet 8 corresponds to a proximity switch 9. The proximity switch 9 is preferably fixed on the housing of the driving motor 6 and is correspondingly located above the metal sheet 8.
