When opening, the cylinder 5 compresses, pulling the pull rod 6 to move towards the direction of the cylinder 5 so as to open the upper panel 2; in order to open the upper panel 2 more quickly, an auxiliary cylinder is arranged at one end of the opening (namely, the end far away from the avoidance groove), the auxiliary cylinder is arranged below the fixed frame 1 and is separated from the cylinder 5 at two ends of the opening, and is used for pushing a force-bearing part arranged at the bottom of the upper panel 2 when the door is opened, so as to help the upper panel 2 to be opened quickly; when the door is closed, the auxiliary cylinder can also slow down the impact force of the upper panel 2 on the fixed frame 1. The force receiving portion is provided at the bottom of one end of the upper panel 2 away from the inclined surface 22.
The cylinder 5 is preferably controlled by a three-position four-way pneumatic reversing valve, and the auxiliary cylinder is preferably controlled by a two-position three-way pneumatic reversing valve. When the door is opened, the cylinder 5 drives the piston rod of the cylinder to drive the pull rod 6 to pull the upper panel 2, and meanwhile, the piston end of the auxiliary cylinder is ventilated, the piston rod of the auxiliary cylinder pushes forwards to push the stress part arranged at the bottom of the upper panel 2, so that the upper panel 2 is pushed away; when the door is closed, the cylinder 5 drives the piston rod to drive the pull rod 6 to push towards the auxiliary cylinder, and when the stress part of the upper panel 2 is contacted with the piston rod of the auxiliary cylinder, the throttle valve arranged on the exhaust pipe of the auxiliary cylinder can control the exhaust amount of the throttle valve, so that the piston rod of the auxiliary cylinder is slowly retracted, the door closing speed of the upper panel 2 is slowed down, and the door is completely closed.
The upper panel 2 is provided with an inclined surface 22 for guiding on one end surface near the cover plate part 11, so that the upper panel 2 can slide smoothly when being opened or closed, and is not blocked. To ensure that the upper panel 2 must fall completely into the opening when closed, the length of the opening is greater than the length of the upper panel 2. In the closed state, a proper gap is left between the end of the upper panel 2 with the inclined surface 22 and the cover plate portion 11. According to the door opening structure of the press residual frame of the extruder, when the extruder is in a closed state, the cover plate part 11 is flush with the upper panel 2, the tops of the upper panel 2 and the cover plate part 11 are flush with the ground, and when the extruder is opened, the upper panel 2 and the cover plate part 11 are overlapped. The upper part of the pressing residual frame is provided with a guide chute, the guide chute is arranged under the ground, the upper part of the guide chute is used for receiving pressing residual materials of the extruder, and the lower part of the guide chute is communicated with the pressing residual frame so as to collect the pressing residual materials. The excess material falls into the excess frame from the guide chute, and when necessary, the upper panel 2 can be opened, and the excess material can be directly taken out from the opening.
The invention adopts automatic control, when the door is opened, the door opening switch of the driving device is pressed, the air cylinder 5 pulls the pull rod 6, the roller 4 rolls and climbs to the translation part 32 along the rising part 33 in the chute 3, then rolls in the horizontal direction in the translation part 32 to drive the upper panel 2 to move towards the cover plate part 11, in the process, the upper panel 2 also has a certain height to be lifted while moving horizontally until the upper panel 2 is integrally covered on the cover plate part 11 of the fixed frame 1, the driving device stops driving, and the opening is completely opened; when the door-closing switch of the driving device is pressed during closing, the air cylinder 5 pushes the pull rod 6, the roller 4 firstly rolls to the rising part 33 along the horizontal direction in the chute 3, then rolls down along the rising part 33 to drive the upper panel 2 to move towards the opening direction, in the process, the upper panel 2 also has a certain height to descend while moving horizontally until the inclined surface 22 arranged on the end surface of the upper panel 2 completely falls into the opening, the driving device stops driving, and the opening is completely closed.
As another embodiment, a detecting device and an alarm device are arranged below the fixed frame 1 of the invention, and the detecting device is used for detecting whether the residual pressing materials in the residual pressing frame are full or not. The detection device preferably adopts infrared detection, is arranged at the upper part of one side wall of the residual pressing frame and is lower than the position of the fixed frame 1, and when residual materials in the frame are piled up to exceed the height of infrared detection, the alarm device gives an alarm to inform staff of timely cleaning.
The whole door opening structure of the extrusion machine residual pressing frame is flush with the ground when the door opening structure is in a closed state, so that the accident probability of workers can be reduced to the minimum, and the personal safety of the workers is ensured; when needed, the upper panel is opened by the control cylinder through the automatic control system, so that the pressing residual material can be taken out, the labor is saved, and the working efficiency is improved. When in an open state, the frame door is overlapped with the cover plate part of the fixed frame, so that the space is saved, and the opening of the residual pressing frame can be maximized. The roller and the chute are in point contact, so that the contact area between the roller and the chute can be reduced to the greatest extent, friction force is reduced, the roller can flexibly move in the chute, and the blocking phenomenon is prevented.
