Problems solved by technology

Its disadvantages are: due to the need to control the swing of the belt, it is necessary to clamp the belt on both sides during installation, which can easily cause the edges of the belt on both sides; the clamping force of the belt on the belt is large, and when the belt is running In this case, the high friction between the belt and the retaining strips will cause excessive wear of the belt and reduce the service life of the belt; affected by the belt processing technology, it is difficult to guarantee the width error of the belt and the straightness error of the side, and the belt will still remain between the retaining strips. will shake left and right

Embodiment

[0022] Embodiment: a kind of belt correction device (see image 3 ), which is characterized in that it consists of a pressure wheel assembly and a roller rib assembly; the pressure wheel assembly presses the belt 2 and forms an angle α with the shortest line in the width direction of the belt 2; the roller rib assembly and the belt 2 wherein Side contact, roller rib assembly is the positioning and datum of belt 2.

[0023] The pinch wheel assembly includes a bracket 4-1 and a pinch wheel 4-2; the pinch wheel 4-2 in the pinch wheel assembly is mounted on the bracket 4-1 and presses the belt 2, the bracket 4-1 and the pinch wheel 4 -2 and the shortest line in the width direction of the belt 2 form an angle α. (See image 3 )

[0024] The angle α is 15°. (See image 3 )

[0025] The pressure wheel assembly is divided into two groups. (See image 3 )

[0026] The roller rib assembly includes 39 rollers 5 . (See image 3 )

[0027] Its outer side of each roller 5 in the...

Abstract

The invention provides a belt correction device. The belt correction device is characterized in that the belt consists of a pressure wheel assembly and a roller wheel flange assembly; the pressure wheel assembly presses the belt and forms an angle alpha with the shortest connecting line at the width direction of the belt; the roller wheel flange assembly is in contact with one side of the belt; the roller wheel flange assembly is used as the reference for positioning the belt. The working method comprises the following steps that the belt runs according to the working direction; in the running process of the belt, the belt laterally moves to the roller wheel flange assembly under the action of the inclined pressure wheel assembly; and one side of the belt is in contact with the roller wheel flange assembly to block the side, so that the side is tightly close to the roller wheel flange assembly to move right forwardly. The device and the method provided by the invention have the advantages that the belt positioning is accurate and stable; the defect brought by accuracy error of the belt is overcome; as the belt is positioned at single side, the requirement on positioning accuracy for a wide belt to convey printed goods for a long distance is ensured; and in addition, the inclined angle of the pressure wheel assembly is small, the belt is gradually close to the single-sided roller wheel flange assembly in the movement, so that the belt can be positioned stably.

Description

(1) Technical fields: [0001] The invention relates to a belt straightening device on a printing machine, which is especially suitable for a device that uses a wide flat belt on the printing equipment to transport printed products. (2) Background technology: [0002] In the sheet-fed conveying equipment, the swing amount of the flat belt during the conveying process directly affects the processing accuracy of the equipment. Therefore, it is extremely important to control the swing amount of the wide belt. [0003] Orthotic devices in the prior art (see figure 1 , figure 2 ) is to use the transmission side bar 1-1 and the operation side bar 1-2 to press the two sides of the width of the belt 2, a groove is formed between the bar and the platform, and the two sides of the belt are stuck in the groove to control The left and right swing of the belt can improve the positioning accuracy of printed products. Its disadvantages are: due to the need to control the swing of the be...
