[0002] In the entire production process of glass bottles, feeders and bottle making machines are the main equipment on the glass bottle production line. In the feeder, the shearing mechanism is the main component of the feeder. The shearing mechanisms commonly used in the feeder include flat shearing mechanism and angle shearing mechanism.

[0003] The entire glass bottle production process involves a lot of equipment, such as the flat shear mechanism used on the feeder, and the subsequent equipment includes the bottle making machine, etc. When the subsequent equipment fails due to electrical reasons, the circuit needs to be stopped, so the shear mechanism needs to be stopped urgently. Or, because the feeder connected to the flat shear mechanism drops the material too quickly, the shearing speed cannot keep up, and the glass drop is in contact with the shear blade for a long time, which also requires an emergency stop and adjustment of the drop time. There are many unexpected situations during production, and they are difficult to predict. As the front end of the entire production process, it is necessary to stop the shearing immediately in the event of an emergency. The shearing mechanism is generally driven to close and open by a drive device, and shears the material when closed. In an emergency, if there is no protection mechanism to protect the shearing mechanism, the shearing mechanism continues to work normally, and the glass drop will cause damage to the shearing mechanism.

The two guide mechanisms enable the drive arm 2 to form a stable rectangle for translation, thereby enabling the shearing mechanism to shear more smoothly and improve product quality.

[0038] Working process:

[0039] The linear motor 9 is controlled to move the two drive arms 2 left and right, driving the corresponding connecting blocks 7, thereby positioning the shearing mechanism at the center of the shearing. One end of the drive arm 2 slides on the guide rail 11 via the slider 12, while the other end slides in the guide groove 101 via the guide sleeve 201. The two guide mechanisms allow the drive arms 2 to form a stable rectangle for translation, keeping the entire shearing process horizontal and improving product quality. While working, cooling air is blown through the vent 401, which blows the linear motor 9 through the cooling groove 601, preventing the linear motor 9 from overheating. The cylinder 5 is also ventilated to ensure that in an emergency, the telescopic rod of the cylinder 5 drives the driven column 14 to press against the action part of the limit block 3, pushing the drive arm 2 open to prevent dripping material from falling on the shearing mechanism.
