The preforming device of thermoforming machine stacker mechanism
Technical field
The utility model relates to a kind of stacker mechanism of thermoforming machine, more specifically to a kind of preforming device of thermoforming machine stacker mechanism.
Background technology
At present, multistation thermoforming machine production line adopt usually stacker mechanism collect finished product.On multistation thermoforming machine production line, sheet material is shifted into the enterprising windrow of stacking station successively and folds after thermoforming, stamping-out, to collect.Goods after stamping-out, in order to stacking station can be displaced to smoothly, goods can not be thrust completely when stamping-out, several points must be left and sheet material is connected to, goods are taken on stacking station by pulling sheet material, and then with punch, goods depart from (part that after punching press, sheet material is remaining is waste paper) from sheet material.
General stacker mechanism is provided with drift, supporting plate in frame, and drift quantity is determined by chamber number, and supporting plate adopts polylith baffle for separating (as Figure 4-Figure 6) by chamber number.Send sheet chain to haul sheet material and move to the motion of stacking station and stopping, described sheet material is strained by sending sheet chain, and sheet plane held by supporting plate.Then, drift sweeps away and goods is pressed onto in supporting plate separate space.Finally, conveyer belt is sent the finished product of goods in order.
Due in mechanism, sheet material is only held by the sheet chain that send on both sides, and both sides send the span of sheet chain large, therefore easily occur the situation of gap in the middle part of sheet material, this easily causes drift to thrust freely, be difficult to punching press, cause goods cannot depart from from sheet material, affects the normal work of whole production line.
Summary of the invention
Technical problem to be solved in the utility model is that the sheet material being positioned at middle part for prior art can not get the shortcoming of good support, a kind of preforming device of thermoforming machine stacker mechanism is provided, sheet material can be clamped between supporting plate by the preforming device of this thermoforming machine stacker mechanism, efficiently avoid and occurs gap phenomenon.The technical scheme adopted is as follows:
A kind of preforming device of thermoforming machine stacker mechanism, comprise frame, supporting plate, drift, drift driving mechanism and two send sheet chain, described supporting plate is arranged in frame, supporting plate adopts polylith baffle for separating by chamber number, drift is contained in drift driving mechanism lower end, it is characterized in that: described preforming device also comprises tablet press mechanism, described tablet press mechanism comprises plate bracket, top board, reciprocating mechanism, described top board is arranged on plate bracket, plate bracket connects the piston axle of reciprocating mechanism, and described top board is positioned at above supporting plate.Goods after stamping-out are followed after sheet material is sent sheet chain to move to stacking station and are sent the stop motion of sheet chain, then reciprocating mechanism drives pressing plate bearing support to drive top board to move downward, make top board press toward supporting plate, clamp sheet material, then drift driving mechanism drives drift to move downward, goods are pressed onto in supporting plate separate space.Due in punching course, sheet material is clamped by top board and supporting plate all the time, therefore there will not be gap phenomenon, makes drift can sweep away finished product swimmingly.
Preferably scheme, the shape of described top board is identical with the shape of supporting plate.Can coordinate better during both contacts like this, sheet material is clamped.
Preferably scheme, the number of described reciprocating mechanism is two, and the two ends of described top board connect the motion end of two reciprocating mechanisms respectively by plate bracket.
The first scheme, described reciprocating mechanism is cylinder, and the motion end of reciprocating mechanism is the piston axle of cylinder.
First scheme, described reciprocating mechanism is hydraulic cylinder, and the motion end of reciprocating mechanism is the piston axle of hydraulic cylinder.Its shortcoming is, the action of hydraulic cylinder is slower.
The third scheme, described reciprocating mechanism is feed screw nut's reciprocating mechanism, and feed screw nut's reciprocating mechanism comprises motor, screw mandrel, nut, and screw mandrel connects the output shaft of motor, and nut sleeve is on screw mandrel, and the motion end of reciprocating mechanism is nut.
Preferably scheme, described drift driving mechanism is hydraulic cylinder.
Another kind of scheme, described drift driving mechanism is the drive plate that external driving mechanism is driven by transmission mechanism.
The utility model beneficial effect is against existing technologies, owing to being provided with tablet press mechanism, top board coordinates with supporting plate, clamp sheet material, therefore, it is possible to be clamped between supporting plate by sheet material, efficiently avoid and occur gap phenomenon, its structure is simple, be easy to processing, result of use is very good.

Detailed description of the invention
Embodiment 1
As Figure 1-3, the preforming device of the thermoforming machine stacker mechanism in the present embodiment, comprise frame 1, supporting plate 2, drift 3, drift driving mechanism and two send sheet chain 5, described supporting plate 2 is arranged in frame 1, supporting plate 2 adopts polylith dividing plate 6 to separate by chamber number, and drift 3 is contained in drift driving mechanism lower end.In the present embodiment, drift driving mechanism is the drive plate 4 that external driving mechanism is driven by transmission mechanism.
Described preforming device also comprises tablet press mechanism, and described tablet press mechanism comprises plate bracket 7, top board 8, reciprocating mechanism, and in the present embodiment, reciprocating mechanism is cylinder 9.
Described top board 8 is arranged on plate bracket 7, and plate bracket 7 connects the piston axle of cylinder 9, and described top board 8 is positioned at above supporting plate 2.Described cylinder 9 is arranged on cylinder supports frame 10.
The shape of described top board 8 is identical with supporting plate 2.Can coordinate better during both contacts like this, sheet material is clamped.
The number of described cylinder 9 is two, and the two ends of described top board 8 connect the piston axle of two cylinders 9 respectively by plate bracket 7.
Introduce the course of work below:
First, goods 12 after stamping-out station stamping-out are followed after sheet material 11 is sent sheet chain 5 to drive stacking station and are sent sheet chain 5 stop motion, then cylinder 9 drives pressing plate bearing support to drive top board 8 to move downward, make top board 8 press toward supporting plate 2, clamp sheet material 11, then drive plate 4 drives drift 3 to move downward, the goods 12 on sheet material 11 is pressed onto in the separate space of supporting plate 2.Due in punching course, sheet material is clamped by top board 8 and supporting plate 2 all the time, therefore there will not be gap phenomenon, makes drift 3 can sweep away finished product swimmingly.Just back move after drift 3 sweeps away finished product, get back to initial position, then top board 8 up moves, sets back.
Then, send sheet chain 5 to recover motion, continue to send sheet, carry out next working cycles.
