[0002] The plaster sticking is a common treatment method in traditional Chinese medicine clinical treatment, and the processing method of the traditional black plaster is to coat a layer of circular plaster on the sheet-shaped base material. The existing automatic plaster production equipment such as CN215779998U discloses an automatic plaster spreading device, and its working principle is that the ointment flows into the medicine distribution disc from the discharge hole at the bottom of the discharge cavity, and then the ointment flowing from the medicine distribution hole is uniformly spread on the medicine cloth through the rotating medicine distribution disc; then the conveying belt continues to convey, and the isolation film on the film collecting and releasing roller is attached to the medicine cloth to isolate the plaster, the height between the isolation film on the film collecting and releasing roller and the medicine cloth is limited by the pressing plate, when the plaster on the medicine cloth moves to the bottom of the pressing block, the pressing block is pushed downward by the first electric push rod on the supporting frame, so that the heat-resistant soft pad at the bottom of the pressing block contacts with the isolation film, thereby pressing the plaster between the isolation film and the medicine cloth, so that the plaster becomes more flat and uniform, thereby forming.

[0003] In the existing automatic plaster production equipment, since the position of the pressing block is fixed, when the plaster moves to the lower side of the pressing block, the transmission belt needs to stop running first, and after the pressing block completes pressing, the transmission belt continues to run, which leads to the discontinuity of the plaster production process, thereby reducing the production efficiency of the plaster.
