Abstract
The utility model relates to an automatic hydraulic expansion device for a rewinding and unwinding machine. The device is characterized by comprising a plurality of expanding and shrinking blocks (3), a central shaft (4) and a spindle (7), wherein the central shaft is arranged inside the spindle; one end of the central shaft is connected with a cylinder at the left end of a frame; a positioning disc (9) is fixed at the periphery of the middle of the spindle; radial chutes of which the number is equal to that of the expanding and shrinking blocks are uniformly distributed on the positioning disc; pairs of wedge blocks (11) are arranged between the expanding and shrinking blocks and the spindle and are clamped with a disc (13) which is sleeved on the spindle; and the disc is connected with a central shaft joint (12) which is arranged at the right end of the spindle through a connecting rod (14). A winding shaft part of the rewinding and unwinding machine can be expanded and shrunk through a hydraulic device, the metal plates can be fixed on the rewinding and unwinding machine without other modes, and the yield of the product can be improved.
Description
Technical field
The utility model relates to a kind of unwinding and rewinding machine automatic hydraulic harmomegathus device, relates in particular to the unwinding and rewinding machine automatic hydraulic harmomegathus device on a kind of double-sided metal sheet material covering film line.
Background technology
Double-sided metal sheet material covering film manufacturing line carries out blowing, rewinding and discharging through the unwinding and rewinding machine to sheet metal, and wherein the volume head of unwinding and rewinding machine plays main effect.Because each is different by the product specification that sheet metal processes, need often to add to change reel, and in discharging, need realize through instruments such as cranes, cause production efficiency to reduce.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of unwinding and rewinding machine automatic hydraulic harmomegathus device is provided, and enhances productivity, and makes things convenient for the workman to operate.
The purpose of the utility model is achieved in that a kind of unwinding and rewinding machine automatic hydraulic harmomegathus device, and it comprises a plurality of harmomegathus pieces, mandrel and main shaft, and said main shaft is a hollow shaft; It is installed on the frame through bearing seat; Said mandrel is arranged at main shaft inside, and an end of said mandrel links to each other with the oil cylinder of frame left end, is fixed with dowel disc in the periphery, middle part of said main shaft; On said dowel disc, be evenly distributed with the radial groove that equates with the harmomegathus number of blocks; One end of said harmomegathus piece is connected with radial groove, and the periphery of harmomegathus piece rectangular distribution and main shaft forms a cylindrical roll head, between said harmomegathus piece and main shaft, is provided with many to voussoir; Said many to voussoir be nested with the disk clamping on main shaft, disk links to each other through connecting rod with the mandrel joint that is arranged on the main shaft right-hand member.
Between said mandrel and main shaft, be provided with sliding sleeve.
Compared with prior art, the beneficial effect of the utility model is:
The spool part of the utility model unwinding and rewinding machine can rise big through hydraulic efficiency gear and dwindle; Sheet metal can not need adopt alternate manner just can be fixed on the unwinding and rewinding machine, does not need to add in addition reel again, improves the yield rate of product; Simultaneously can simplify discharge process, enhance productivity.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the birds-eye view of Fig. 1.
