Description

Technical Field

[0001] The utility model relates to the technical field of cigarette rolling equipment, in particular to a spiral wire return protection door position limiting protection device. Background Art

[0002] The ZJ118 cigarette rolling and connecting unit is a widely used cigarette production equipment in tobacco enterprises. The equipment has the characteristics of advanced technology, beautiful appearance and convenient maintenance. For example, modular design is applied, the structure between each component is clear, the function is clear, and the maintenance is convenient. After the machine has been running for a long time, it is necessary to open each protective cover, regularly clean and maintain each component, and check the operating status of each component to keep the equipment in good operating condition at any time. The spiral wire return protection door is a spiral wire return rear door located on the steep angle wire lifting device. This is a safety protection door. During the operation of the equipment, it can protect the personal safety of the operator and prevent debris from entering the machine. At the same time, it can reduce noise to a certain extent. The spiral wire return protection door is mainly composed of a door body, a door frame, a door lock, and a hinge. The door lock can be freely rotated 45°. When the door latch of the door lock is at the 12 o'clock position, the door latch is buckled into the door frame, and the spiral wire return protection door is locked. When the door latch is at the 3 o'clock position, the door latch is disengaged and the protection door can be opened.

[0003] During the repair and maintenance process, the technicians found that when the steep-angle wire lifting device was opened outward, as the opening angle changed, the bolt on the upper part of the spiral wire return protection door gradually separated from the door panel and lost its locking function, so that when the steep-angle wire lifting device was not fully opened, the spiral wire return protection door automatically rotated from top to bottom and opened. However, during the process of the steep-angle wire lifting device being continuously opened, the upper side of the spiral wire return protection door had rotated to touch the ground, and the spiral wire return protection door formed a supporting point with the ground. Under the action of the gravity of the spiral wire return protection door, the hinges connecting the guard plate under the door body of the spiral wire return protection door could not bear the weight and were damaged.

Exemplarily, the diameter of the nut is smaller than the diameter of the receiving groove 112. Preferably, the receiving groove 112 is a circular groove, and the receiving groove 112 is coaxially arranged with the connecting hole 111.

[0033] In some embodiments, the base 100 is provided with an installation hole 130, and a screw passes through the installation hole 130 and is threadedly connected to the door body of the spiral wire return protection door, thereby realizing a detachable connection between the base 100 and the door body of the spiral wire return protection door, facilitating disassembly and assembly of the base 100.

[0034] In some embodiments, the end of the column 300 away from the cylinder 310 is provided with an external thread 320, and the external thread 320 is threadedly connected to the door frame of the spiral wire protection door, so as to facilitate the disassembly and assembly of the external thread 320 and the door frame of the spiral wire protection door. The side wall of the column 300 is provided with a mounting section 330, and the cross section of the mounting section 330 is hexagonal. The wrench can clamp the mounting section 330, and the wrench is pulled to rotate the column 300, so that the column 300 is threadedly connected to the door frame of the spiral wire protection door. Of course, in other embodiments, the cross section of the mounting section 330 can also be a quadrilateral or an octagon.
