Abstract
The utility model provides a rack synchronous mechanism for an automatic laminator, which comprises a motor and is characterized by further comprising an upper synchronous shaft and a lower synchronous shaft. An upper pressing unit gear and a lower pressing unit gear are respectively sleeved on the upper synchronous shaft and the lower synchronous shaft. A synchronous wheel and a group of rack pinions of the upper synchronous gear are arranged at two ends of the upper synchronous shaft respectively, the motor drives the synchronous wheel through a short-range synchronous belt, the rack pinions of the upper synchronous gear are connected to a group of rack pinions of the lower synchronous gear arranged at one end of the lower synchronous shaft through a linear plain shaft. The rack synchronous mechanism for the automatic laminator has the advantages that the rack pinions of the gears which serve as the synchronous driving mechanisms of the upper and lower pressing unit gears enable the synchronization to be more accurate. Furthermore, a cylinder is used for driving the upper and lower pressing unit gears to return, so that the response is more rapid.

Further, be provided with brake at the described other end of synchronizing shaft down.
The described synchromesh gear tooth bar pair that goes up comprises and intermeshingly goes up the synchronizing shaft gear and go up synchronous tooth bar, on the end of last synchronizing shaft geared sleeve synchronizing shaft on described.
On described the synchronizing shaft gear and on be provided with idle gear between the tooth bar synchronously, idle gear is respectively with last synchronizing shaft gear and go up synchronous tooth bar and be meshed.
Described synchromesh gear tooth bar pair down comprises that intermeshing synchronous tooth bar down reaches synchronizing shaft gear down, and following synchronizing shaft geared sleeve is outside an end of described synchronizing shaft down.
In order to reach further purpose, synchronizing shaft is equipped with on the end of described synchronizing wheel and is provided with clutch on described.
The piston rod of cylinder connects described synchronous tooth bar or the described synchronous tooth bar down, and described synchronous tooth bar or described synchronous tooth bar are down followed stretching out of piston rod or bounced back and do rectilinear motion.
The utility model has the advantages that: with rack-and-pinion as on pressing down the synchronous drive mechanism of unit, make more accurate synchronously.Further, drive with cylinder and to press down the unit and return, make that response is quicker.

The specific embodiment
For the utility model is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
As shown in Figure 1, a kind of tooth bar lazy-tongs that are used for automatic press mold machine that provide for the utility model, comprise motor 1, last synchronizing shaft 5 and following synchronizing shaft 15, on pressing unit gear 6 and pressing down that unit gear 13 is enclosed within synchronizing shaft 5 respectively and down on the synchronizing shaft 15, be respectively equipped with synchromesh gear tooth bar pair on synchronizing wheel 3 and a group at the two ends of last synchronizing shaft 5.In conjunction with Fig. 2, motor 1 is with 2 to drive synchronizing wheel 3 by short distance synchronously, at the synchronizing wheel 3 other clutches 4 that are provided with.Synchromesh gear tooth bar pair under one group of synchronizing shaft 15 1 ends was provided with brake 14 under last synchromesh gear tooth bar pair was positioned at by 9 connections of straight line optical axis on the other end of following synchronizing shaft 15.
As shown in Figure 3, last synchromesh gear tooth bar pair comprises synchronizing shaft gear 7, last synchronous tooth bar 8 and idle gear, and idle gear is meshed with last synchronizing shaft gear 7 and last synchronous tooth bar 8 respectively, and last synchronizing shaft gear 7 is enclosed within on the end of synchronizing shaft 5.
As shown in Figure 4, following synchromesh gear tooth bar pair comprises that intermeshing down synchronous tooth bar 11 reaches synchronizing shaft gear 12 down, and following synchronizing shaft gear 12 is enclosed within outside the end of described synchronizing shaft 15 down.The piston rod that is fixed on the cylinder 10 on the cylinder block connects synchronous tooth bar 11 down, and following synchronous tooth bar 11 is followed stretching out of piston rod and done rectilinear motion.
In conjunction with Fig. 1, link to each other by straight line optical axis 9 between following synchronous tooth bar 11 and the last synchronous tooth bar 8.
Discuss the course of work of present embodiment below in conjunction with Fig. 1:
Drive synchronizing wheel 3 by motor 1, clutch 4 adhesives, synchronizing wheel 3 drives to be gone up synchronizing shaft 5 and rotates, on pressing unit gear 6 to drive to press the unit to move downward.Last synchronizing shaft gear 7 drives goes up upwards rectilinear motion of synchronous tooth bar 8, go up synchronous tooth bar 8 together with straight line optical axis 9 and down synchronous tooth bar 11 motions, following synchronous tooth bar 11 drives synchronizing shaft gear 12 rotations down, drives and is pressing down unit gear 13, moves upward thereby driving is pressing down the unit.The upper and lower unit motion clutch 4 when the piston rod of cylinder 10 is withdrawn fully of pressing unclamps, and 14 adhesives of braking simultaneously maintain the upper and lower cell position of pressing.When upper and lower when pressing the unit to need that response is returned fast, because clutch 4 unclamps, having cut off last synchronizing shaft 5 is connected with the power of motor 1, at this moment, piston rod by cylinder 10 stretches out, and will descend synchronous tooth bar 11 to press down, and drives synchronizing shaft gear 12 rotations down by down synchronous tooth bar 11, drive is pressing down unit gear 13, and to press down the unit downward thereby drive.Simultaneously, down synchronous tooth bar 11 by straight line optical axis 9 drive go up synchronous tooth bar 8 together straight line move downward, go up synchronous tooth bar 8 and drive and go up 7 rotations of synchronizing shaft gear, pressing unit gear 6 in the drive, thereby pressing the unit downward on driving, finally finishing upper and lower snap back motion of pressing the unit.
