The bubble stabbing device for the calender can achieve production of products with different widths, adjusts total distance of reciprocating motion of knife heads, main parts are the chain wheel, the chain and the like, so that machining precision of parts is low, machining and production costs of a machine are low, the operation can be achieved through a general variable frequency motor and a voltage/frequency (V/F) control mode inverter, so that electric control cost is low.

Description

The thorn air bubble apparatus that calender is used

Technical field

The utility model relates to the thorn air bubble apparatus that a kind of calender is used.

Background technology

Calender can be mingled with some bubbles in the calender line mesoglea or between glue-line and roll surface, the existence impact calendering quality of these bubbles, generally the applying roller at calender is equipped with the thorn air bubble apparatus, this device scratches the glue face on the roller, make gas overflowing, the thorn air bubble apparatus generally generally adopts two kinds of structures: the chuck block that the first adopts the rotation drive of positive and negative screw rod to be loaded on the slide moves around, break bar on the chuck block scratches glue-line, the second adopts high-quality variable-frequency motor to drive the positive and negative rotation of ball screw, and ball screw drives the chuck block that is loaded on the slide and moves around.The structural disadvantages of the first thorn air bubble apparatus is: the processing of forward lead screw is difficulty relatively, when the cord of calendering different in width, the distance that break bar moves can not be adjusted, the shortcoming of the second structure is: during calender work, variable-frequency motor needs frequently rotating, electric machine temperature rise is higher, and is higher to the Electric Machine Control performance requirement, so cost is higher.

The utility model content

The purpose of this utility model provides the thorn air bubble apparatus that a kind of calender is used.

The technical scheme that the utility model adopts for achieving the above object is: the thorn air bubble apparatus that a kind of calender is used, comprise the associated mode variable-frequency motor, sprocket wheel, chain, axle, the first support, the first duplex chain wheel, double strand chain, the second duplex chain wheel, the second support, tensioning spring, pin, linear bearing, coulisse, knife rest, three cutter heads and screw mandrel, the associated mode variable-frequency motor is connected on the power shaft of reductor, sprocket wheel is installed on the output shaft of reductor, chain is installed in an end of axle, the first duplex chain wheel is installed in the other end of axle, axle is installed on the first support, the second duplex chain wheel, tensioning spring is installed on the second support, double strand chain is connected between the first duplex chain wheel and the second duplex chain wheel, pin and linear bearing are fixed on the chain, one end of pin is inserted in the chute of coulisse, coulisse is fixed on the slide of linear bearing, three cutter heads are fixed on the coulisse, three middle cutter heads of cutter head are fixed on the knife rest, the cutter head of the right and left is installed on the slide block of linear bearing, and screw mandrel is connected between three cutter heads.

Described axle is installed on the first support by bearings.

The thorn air bubble apparatus that a kind of calender of the utility model is used, knife rest can be followed roller within calender left and right arms plate friction speed moves back and forth with different speed, and three cutter heads can adapt to the film that calender is produced different in width, displacement is adjustable not needing to realize the frequent rotating of motor, break bar is automatically reciprocating, can realize the difference of article of manufacture width, adjust total distance that cutter head moves back and forth, major part is sprocket wheel, chain etc., part processing precision is low, and the machined production cost is low, the logical variable-frequency motor of one Daepori and V/F control model frequency converter can realize that automatically controlled cost is low.

Description of drawings

Fig. 1 is the structural representation of the thorn air bubble apparatus used of a kind of calender of the utility model.

Fig. 2 is that the A-A of Fig. 1 is to view.

Fig. 3 is that the B-B of Fig. 1 is to view.

Fig. 4 is that the C-C of Fig. 1 is to view.

Fig. 5 is that the D of Fig. 2 is to view.

Among the figure: 1. associated mode variable-frequency motor, 2. sprocket wheel, 3. chain, 4. axle, 5. the first support, 6. the first duplex chain wheel, 7. double strand chain, 8. the second duplex chain wheel, 9. the second support, 10. tensioning spring, 11. pins, 12. linear bearing, 13. coulisses, 14. knife rests, 15. cutter heads, 16. screw mandrels.

The specific embodiment

Extremely shown in Figure 5 such as Fig. 1, the thorn air bubble apparatus that calender is used, comprise associated mode variable-frequency motor 1, sprocket wheel 2, chain 3, axle 4, the first support 5, the first duplex chain wheel 6, double strand chain 7, the second duplex chain wheel 8, the second support 9, tensioning spring 10, pin 11, linear bearing 12, coulisse 13, knife rest 14, three cutter heads 15 and screw mandrel 16, variable-frequency motor 1 is according to the operating rate of calendering main frame roller, export different rotating speeds, this motion is through the speed change output of reductor, sprocket wheel 2 is installed on the output shaft of reductor, drive chain 3, chain 3 is installed in an end of axle 4, the other end of axle is equipped with the first duplex chain wheel 6, axle 4 is installed on the first support 5 by bearings, the rotation of chain 3 can drive the rotation of the first duplex chain wheel 6, another second duplex chain wheel 8 is installed on the second support 9, on the second support 9, tensioning spring 10 is housed also, the nut that turns on the tensioning spring makes the second duplex chain wheel 8 move to the direction away from the first duplex chain wheel 6 with regard to compressible tensioning spring, thereby tensioning double strand chain 7, because double strand chain adopts the double strand chain with annex, therefore can be on chain steady pin and linear bearing, when the first duplex chain wheel 6 rotates, can drive the second duplex chain wheel 8, make and be fixed on the chain pin 11 and between the first duplex chain wheel 6 second duplex chain wheels 8, move reciprocatingly, coulisse 13 is fixed on the slide of linear bearing 12, above it by the chute of a bar shaped, be inserted with the other end of pin 11 in the chute, when pin 11 is reciprocating, it is reciprocating just to drive coulisse 13, three fixing cutter heads also can be followed coulisse and be done same motion on the coulisse, a cutter head is fixed on the knife rest 14 in the middle of three cutter heads 15, the cutter head of the right and left is installed on the slide block of linear bearing, on 2 linear bearing mounting tool posts 14, therefore the cutter head of the right and left can along away from/move near the direction of middle cutter head, turn screw mandrel 16 with regard to the distance between the cutter head of the capable of regulating left and right sides, with the total distance that realizes that cutter head moves back and forth.
