Abstract
The invention discloses a screw extruder safety device convenient for safety disc replacement. The screw extruder safety device comprises a safety seat (6) mounted on a bearing seat (7), wherein a safety gasket seat (5) capable of moving along an axial direction of the bearing seat (7) is arranged in the safety seat (6), and the safety gasket seat (5) comprises a cavity (9) on which a safety disc (4) is arranged. The screw extruder safety device is simple in structure, convenient and rapid for mounting and use, the halt time for maintaining the apparatus is short, and the production efficiency of the device is greatly improved.
Description
Technical field
The present invention relates to a kind of rubber plastic machinery, specifically a kind of screw extruder particularly relates to a kind of screw extruder safety device.
Background technology
Screw extruder is when work, for preventing that the film extrusion pressure from surpassing extruder and setting relevant devices such as roll adjustment screw mandrel screw pair that safe load damages cylinder or be connected with cylinder, reductor, motor, on the bearing block of last cylinder, be provided with a safety device.Promptly when film extrusion pressure overload occurring, the Connection Block on the roll adjustment screw mandrel damages the safety disc in the safety device and reports to the police and shut down.Existing safety device is because be enclosed construction, emergency seat and safety pad bar are overall structure, when changing safety disc, need to change behind the parts such as dismounting roll adjustment screw mandrel, gland, not only waste time and energy, and influence the normal use of equipment, and then influence production efficiency, cause the waste of production capacity.
Summary of the invention
The purpose of this invention is to provide a kind of screw extruder safety device that is convenient for changing safety disc.
The present invention adopts following technical scheme to realize its goal of the invention, a kind of screw extruder safety device, it comprises the emergency seat that is installed on the bearing block, it is characterized in that being provided with in the emergency seat safety pad bar that can move along the bearing block axial direction, described safety pad bar comprises a cavity, and cavity is provided with safety disc.
The present invention is a conveniently moving, and described safety pad bar is provided with handle.
Because adopt technique scheme, the present invention has realized goal of the invention preferably, it is simple in structure, installation, easy to use, quick, and the equipment downtime maintenance time is short, has improved efficiency of equipment greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of safety pad bar 5;
Fig. 3 is the vertical view of Fig. 2.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
By Fig. 1, Fig. 2, Fig. 3 as can be known, a kind of screw extruder safety device, it comprises the emergency seat 6 that is installed on the bearing block 7, bearing block 7 is installed on the cylinder, gland 2 is installed on the emergency seat 6, gland 2 forms a chamber with emergency seat 6, the top in chamber is equipped with roll adjustment screw mandrel 1, Connection Block 3 is connected with roll adjustment screw mandrel 1 by screw, the bottom in chamber is equipped with the safety pad bar 5 that can move along bearing block 7 axial directions, described safety pad bar 5 comprises a cavity 9, and cavity 9 is provided with safety disc 4, and safety disc 4 contacts with 3 of Connection Blocks.
Be conveniently moving, safety pad bar 5 is provided with handle 8.
When the present invention works; plate-like safety disc 4 is placed on the safety pad bar 5; when film extrusion pressure overload occurring; bearing block 7 drives on the emergency seat 6 and moves; safety disc 4 is the cracked cavity 9 that falls under Connection Block 3 effect, and checkout gear detects the shutdown of reporting to the police of safety disc 4 fragments in the cavity 9 by the detection hole 10 on emergency seat 6, the safety pad bar 5.When changing safety disc 4, only need to extract safety pad bar 5 out in emergency seat 6, pour out safety disc 4 fragments, the new safety disc 4 of packing into advances safety pad bar 5 in the emergency seat 6 then and promptly finishes replacing.
Claims (2)
