Be applied to the stroke automatic locking positioning device on the screen decorating machine
Technical field
The utility model relates to a kind of screen decorating machine, specifically is meant the stroke automatic locking positioning device that is applied on the screen decorating machine.
Background technology
The characteristics of screen decorating machine require the silk screen frame to aim at following lining is strict, in case the somewhere dislocation, whole cloth will be scrapped.And in the at present general screen printing apparatus, the silk screen frame is fixedly connected to hard and connects, and can so strict aims between silk screen frame and the platen of placing lining, key be by self precision of equipment.Like this self processing request of equipment is wanted high, corresponding manufacturing cost is also high, and popularity rate is lower in the industry.
The utility model content
The utility model provides the stroke that is applied on screen decorating machine automatic locking positioning device, the not high shortcoming of Aligning degree between the platen that its main purpose is to overcome existing silk screen frame and place lining.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Be applied to the stroke automatic locking positioning device on the screen decorating machine; Comprise sign indicating number son and the actuating unit that is used to drive the side-to-side movement of silk screen frame; This yard son comprises the young seat of the sign indicating number that is installed on the platen frame and cooperates with the young seat of sign indicating number and be installed in the inductive head on the silk screen frame; Offer groove on the young seat of this yard, and it also is provided with the inductor that cooperates and be used to control the actuating unit break-make with inductive head, said inductive head is provided with the bullet bolt that carries out clamping matching with groove.
The young seat of aforementioned sign indicating number is provided with a plurality of, and it is along the platen frame length direction layout of being separated by.
Aforementioned actuating unit is a servomotor.
Can know by above-mentioned description the utility model structure; Compare with prior art; The utlity model has following advantage: this stroke automatic locking positioning device adopts the sign indicating number son and is assemblied in the young design of going up inductor of sign indicating number; Make on silk screen frame and the workbench that in order to accurate positioning between the platen of placing lining, the silk screen frame is difficult for positioning, has reduced the defect rate of product.During action, when the inductor on the young seat of sign indicating number was sensed inductive head, it exported signal, makes actuating unit break off, and bullet bolt moves down and is inserted in the groove simultaneously, i.e. silk screen frame stroke lock-bit is accomplished.
Description of drawings
Fig. 1 is the sketch map of the utility model user mode, the state that bullet bolt does not move down.
Fig. 2 is the sketch map of the utility model user mode, the state after bullet bolt moves down.
The specific embodiment
The specific embodiment of the utility model is described with reference to the accompanying drawings.
See figures.1.and.2.Be applied to the stroke automatic locking positioning device on the screen decorating machine; Comprise sign indicating number son and the actuating unit 2 that is used to drive 1 side-to-side movement of silk screen frame; This yard son comprises the young seat 4 of the sign indicating number that is installed on the platen frame 3 and cooperates with the young seat 4 of sign indicating number and be installed in the inductive head 5 on the silk screen frame 1; Offer groove 40 on the young seat 4 of this yard, and it also is provided with the inductor that cooperates and be used to control actuating unit 2 break-makes with inductive head 5, said inductive head 5 is provided with the bullet bolt 50 that carries out clamping matching with groove 40.The young seat 4 of this yard is provided with a plurality of, and it is along the platen frame 3 length directions layout of being separated by.
Above-mentioned actuating unit 2 is a servomotor, and the characteristics of this servomotor are that starting torque is big, and when stator one has control voltage, rotor rotates immediately, and it is fast, highly sensitive promptly to have a starting; When stator one voltage out of hand, rotor shuts down immediately.
The above-mentioned specific embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
