Four-roller tabletting device

Abstract

The invention relates to a four-roller tabletting device. The four-roller tabletting device comprises a rack, an upper supporting roller, a lower supporting roller, an upper rolling roller, a lower rolling roller, a roller distance adjusting assembly used for adjusting the distance between the upper rolling roller and the lower rolling roller, and a power assembly driving the upper supporting roller, the lower supporting roller, the upper rolling roller and the lower rolling roller to rotate, wherein the power assembly comprises a motor driving the upper supporting roller and the lower supporting roller to rotate correspondingly, the roller distance adjusting assembly comprises lead screws arranged on the two sides of the rack correspondingly, two sliding pieces matching with the two leadscrews correspondingly and a driving piece for driving the lead screws to rotate, the two ends of the upper supporting roller and the two ends of the upper rolling roller in the length direction are installed on the two sliding pieces correspondingly, the upper supporting roller is located over the upper rolling roller, the lower supporting roller is located under the lower rolling roller, the central axes of the upper supporting roller, the lower supporting roller, the upper rolling roller and the lower rolling roller are located on the same vertical plane, the diameters of the upper supporting roller, the lower supporting roller are consistent, and the diameters of the upper rolling roller and the lower rolling roller are consistent, the diameter of the upper supporting roller is largerthan that of a upper rolling pipe. The four-roller tabletting device has the effect of improving the accuracy of the rolling thickness of a metal sheet.

Description

technical field [0001] The present application relates to the field of metal sheet pressing technology, in particular to a four-roller tablet pressing device. Background technique [0002] Jewelry involves metal sheets such as gold foil, silver foil, and copper foil. The sheet pressing device is a heavy-duty machine that is commonly used in the production of metal sheets. The sheet pressing device is usually obtained by multi-pass rolling with a two-roller sheeting device. Its function is to roll the metal sheet thinner to meet the needs of jewelry making, so as to facilitate subsequent processing. [0003] In view of the related technologies mentioned above, the inventor believes that there are the following defects: after long-term use of the traditional two-roller tableting device, the two rollers are prone to deformation, resulting in the phenomenon that the rolled metal sheet is prone to appear thick in the middle and thin on both sides. The required rolling thickness ...

Problems solved by technology

[0003] In view of the related technologies mentioned above, the inventor believes that there are the following defects: after long-term use of the traditional two-roller tableting device, the two rollers are prone to deformation, resulting in the phenomenon that the rolled metal sheet is prone to appear thick in the middle and thin on both sides. It makes the rolling thickness required for the metal sheet inaccurate, and it is difficult to meet the needs of the actual processing accuracy of jewelry.
