Abstract
Description
Technical Field
[0001] The utility model relates to a component on a film blowing machine, in particular to a full-automatic foam stabilizing device. Background Art
[0002] The main function of the air ring on the film blowing machine is to cool the film bubbles blown out by the film blowing machine so that they can be quickly formed, thereby achieving the improvement of production efficiency. The film bubble has a certain temperature just after coming out of the mold. It passes through the film stabilizing frame and the herringbone frame and is stretched and rolled up by the winding mechanism. During the traction process, the outer size of the bubble film is mainly fixed by the film stabilizing frame. Otherwise, the outer diameter of the bubble film will be deformed and expanded due to the internal air pressure. The baffles on the traditional film stabilizing frame are all adjusted manually, which is very laborious and inefficient, greatly delaying the progress of the work. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a fully automatic bubble stabilizing device, the purpose of which is to control the movement of the baffles through a servo motor, accurately control the interval between the baffles, and further control the outer diameter of the membrane bubble.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fully automatic foam stabilizing device, comprising a frame, the frame is square in shape, and the four sides of the frame are respectively equipped with rotatable screws, the four screws are divided into front, rear, left and right screws, and the four screws are driven by a servo motor, and also include front, rear, left and right baffles, the left and right baffles are respectively installed on the front and rear screws through the first nut sleeve thread transmission, the front and rear baffles are respectively installed on the left and right screws through the second nut sleeve thread transmission, the two first nut sleeves on the left and right baffles have opposite thread spiral directions, the two second nut sleeves on the front and rear baffles have opposite thread spiral directions, the first nut sleeve of the left / right baffle and the second nut sleeve of the front / rear baffle adopt opposite spiral directions, so as to realize stable expansion or contraction adjustment of the four baffles driven by the servo motor.
[0005] Guide rollers are respectively installed at the upper and lower ends of each baffle.
[0006] The servo motor is fixed on the frame, the output shaft of the servo motor is connected to the front screw, the front screw and the left and right screws are respectively driven by bevel gear meshing, and the right screw and the rear screw are driven by bevel gear meshing.
[0007] The beneficial effects of the present utility model are as follows: The servo motor can drive the four screws to rotate, and then drive the baffles on the screws to move axially along them. Since the spiral directions of the two first nut sleeves and the second nut sleeve are opposite, the servo motor drives the front, rear, left, and right baffles to form a square channel with an expandable or contractible size. The servo motor adjusts the rotation speed and direction of the screws through the controller, accurately adjusts the distance between the baffles, thereby stably controlling the outer diameter size of the film bubble. Compared with the traditional manual adjustment method, the adjustment accuracy and efficiency are significantly improved.
[0008] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments. Description of the Drawings

[0012] The following specifically describes the present utility model through embodiments, which are only used to further illustrate the present utility model and cannot be construed as a limitation of the protection scope of the present utility model.
[0013] As Figure 1 , Figure 2 shown, this embodiment discloses a fully automatic bubble stabilizing device, including a frame 1, the frame 1 is square-shaped, rotatable screws 2 are respectively installed on the four side frames of the frame 1, the four screws 2 are divided into front, rear, left, and right screws 22, the four screws 2 are driven by a servo motor 4, and also include four front, rear, left, and right baffles 3. The left baffle 31 and the right baffle 32 are respectively installed on the front and rear screws 24 through the first nut sleeve by screw drive, the front baffle 33 and the rear baffle 34 are respectively installed on the left screw 23 and the right screw 22 through the second nut sleeve by screw drive. The spiral directions of the two first nut sleeves on the left baffle 31 and the right baffle 32 are opposite, and the spiral directions of the two second nut sleeves on the front baffle 33 and the rear baffle 34 are opposite. The first nut sleeve of the left / right baffle and the second nut sleeve of the front / rear baffle adopt reverse spiral directions, so that the four screws can rotate synchronously and in the correct direction, realizing stable expansion or contraction adjustment of the four baffles driven by the servo motor.
[0014] Guide rollers 5 are respectively installed at the upper and lower ends of each baffle 3. The guide rollers can reduce the frictional resistance of the film bubble and at the same time reduce the film bubble scratching.
[0015] The servo motor 4 is fixed on the frame 1. The output shaft of the servo motor 4 is in transmission connection with the front screw rod 21. The front screw rod 21 is in meshing transmission with the left screw rod 23 and the right screw rod 22 respectively through bevel gears, and the right screw rod 22 is in meshing transmission with the rear screw rod 24 through bevel gears.
[0016] With the above technical solution, the servo motor 4 can drive the four screw rods 2 to rotate, and then drive the baffle 3 on the screw rod 2 to move axially along it. Since the spiral directions of the two first nut sleeves and the second nut sleeve are opposite, the servo motor 4 drives the front, rear, left and right baffles 32 to form a square channel with an expandable or contractible size. The servo motor adjusts the rotation speed and direction of the screw rod through the controller, accurately adjusts the distance between the baffles, so as to stably control the outer diameter size of the film bubble. Compared with the traditional manual adjustment method, the adjustment accuracy and efficiency are significantly improved.
