Description
Technical field
The present invention relates to blister packaging apparatus field more particularly to a kind of mould table elevating mechanisms.
Background technology
Blister packaging equipment needs use mould table structure, mould table to be lifted when handling plastic uptake product,
The lifting of mould table at present interlocks with cylinder and connecting rod, but uses connecting rod, and area occupied is big, up and down space
It is limited by connecting rod.In addition, being directed to the blister packaging of medical industry, required stroke is little, and the movement of cylinder controls connecting rod
It is deep mixed due to blister packaging product without multi-section stroke function, when especially doing shallow product, if using cylinder, due to
The stroke of cylinder is fixed, and cylinder need to drop to original position, can occupy more times, and production efficiency is relatively low.
Invention content
To overcome disadvantages mentioned above, the purpose of the present invention is to provide it is a kind of it is compact-sized, can be suitably used for different depth products,
Improve the mould table elevating mechanism of production efficiency.
In order to reach object above, the technical solution adopted by the present invention is：A kind of mould table elevating mechanism, including mold
Platform, pedestal are provided with the elevating mechanism of control mould table lifting on the pedestal, and the elevating mechanism includes servo motor, circle
Column casing, big belt wheel, ball nut, lead screw and float flange, the ball nut are fixed on the upper end of cylindrical drum, the lead screw
With ball nut screw-thread fit, for the lead screw through ball nut and below mould table, the lead screw is vertical with mould table,
The float flange is fixed at the top for the lead screw for stretching out ball nut, and at least one is fixedly installed on the float flange
A guide post, the guide post are embedded in the bottom of the mould table, and the output end of the servo motor is provided with output gear, institute
Big belt wheel is stated with a circle dentalation, the big belt wheel is fixed on the excircle of cylindrical drum, the big belt wheel and output gear
The synchronous belt of cooperation is arranged on wheel.
The advantageous effect of inventive die platform elevating mechanism is that, when servo motor starts, synchronous belt drives big belt wheel rotation,
Since big band gear is fixed with cylindrical drum, cylindrical drum rotates therewith, and ball nut also rotates, phase between cylindrical drum and ball nut
To static, due to multiple guide posts insertion mould table bottom on float flange, lead screw will not rotate with ball nut, cause to roll
With lead screw relative rotation occurs for pearl nut, and lead screw generation is moved up and down compared to ball nut；By servo motor rotate forward/
Reversion control lead screw lifting, then controls mould table lifting.For the cooperation driving of cylinder and connecting rod, due to lead screw
Lifting has multi-section stroke by Serve Motor Control, servo motor, can be according to the random adjusting control of depth of product；As depth
Shallow product is spent, servo motor makes mould table that need not return to original position, production efficiency can be improved in this way；In addition, using servo electricity
Machine replaces traditional cylinder, and corresponding speed is fast, and power output is constant, further increases the efficiency of complete machine.
Be as a further improvement on the present invention, since the lifting of mould table is directly acted on by lead screw, if mould table with
Lead screw is in direct contact for a long time, then lead screw easily damages, and then causes the service life of lead screw to reduce, is asked to solve this
Topic is provided with lead screw protection structure and extends the service life of lead screw to protect lead screw between the pedestal and mould table.
