Description

S. A. filter core wrapping machine

The utility model relates to a kind of electromechanical integration production facilities that improves the filter core labor efficiency.

At present, domestic existing installation is single head and twines mode of operation, pure mechanical cam feeding structure, contact relay control circuit.Backward in technique, production efficiency is low, can not adapt to the variation of production technology rapidly, productive costs height, poor product quality, maintenance of equipment inconvenience.

The purpose of this utility model provides a kind of production facilities, and it can increase substantially labor efficiency, adapts to the change of production technology rapidly, reduce technology and adjust the time, guarantee the stability of product design, obviously reduce the production site area, make maintenance adjustment, easily and fast.

The purpose of this utility model is achieved in that in Figure 16, this production facilities is made up of three parts, convertible bin (1), cradle (2), wrapping machine (3), wherein convertible bin and cradle, be used for the supply and the conveying of raw material, wrapping machine is finished the filter core task of twining.This production facilities is eight common mode of operation of twining.The positive eight charging tray stations of convertible bin are used for the normal operation feed; reverse side eight charging tray stations are load/unload stations; can effectively reduce reloads shuts down man-hour; the upset of bin is by manually finishing; location, clamping are realized by two locating dowel pins; the loading and unloading of each charging tray are that dish shape nut and open washer are used, and do not need any manipulative device, just can load and unload fast.Because eight working-spindles are in one line, and the charging tray on the convertible bin is arranged on a vertical plane according to certain rules, therefore designed a cradle, with the arrangement of the two, do a cambic conversion, to distribute on the vertical plane surface, be transformed into upper and lower two straight line distribution forms, distribute by the straight line of two straight lines again to wrapping machine feeding air supported head.Adopt forward and backward orifice plate segmentation transition structure, reduced the tension force of stockline.Wrapping machine is work like this: manually load onto the plastics mandrel on eight main shafts, with stockline on mandrel, press the automatic circulation button, two location, clamp turnover panel, drive, Rotate 180 ° by rotating driver, the unsteady top function that realizes locating, clamping with the end face gear ring, main shaft starts, and is fixed on the feeding air supported head on the rigidity sliding panel simultaneously, and winding is finished in left and right motion.This feed system is two air cylinder driven infinite speed variation structures, can left and right two direction infinite speed variations by the rigidity sliding panel of two air cylinder driven.Main shaft adopts variable-frequency governor, realizes infinite speed variation, therefore can adapt to the variation of production technology.Be the precision that guarantees to twine, support beam is provided with the line ball roller device.After winding was finished, main shaft stopped, and braking rapidly, and two location, clamping turnover panel rotate up 180 °, and hand cuts across disconnected each stockline, takes off filter core, finishes a working cycle.All winding process is finished by an industrial programmable controller (PLC), and automatic circulation job procedure and technology adjustment program are arranged in the memory of PLC.For driving the location, clamping turnover panel action and the left and right motion of feeding air supported head, designed pneumatic control system.

Because adopt such scheme, labor efficiency increases substantially, when filter core specification requirement variation, can adjust production technology rapidly, and the production site area occupied reduces obviously, equipment failure rate is low, and maintenance is adjusted, easily and fast.

Below in conjunction with accompanying drawing the utility model is described further.
