Description

Technical Field

[0001] The utility model belongs to the technical field of film blowing machine accessories, in particular to an adjustable air ring of a film blowing machine. Background Art

[0002] The air ring is an important component of the blown film unit of plastic processing machinery, which is responsible for cooling and shaping the blown film bubble. The air ring has a great influence on the quality and output of blown film products.

[0003] In the prior art, a wind disk is rotatably arranged on the surface of the wind ring. When using the film blowing machine, the wind disk on the wind ring needs to be adjusted so that the blown film is aligned with the center of the wind ring. However, the wind disk has the following shortcomings in actual use:

[0004] 1. The positioning effect of the fan disc is poor. It is easy to rotate when subjected to external force, causing the membrane and the fan disc to be misaligned, affecting the quality of the finished product.

[0005] For this reason, we propose an adjustable air ring for film blowing machine. Utility Model Content

[0006] The utility model aims to solve the shortcomings of the prior art that the wind disk has a poor positioning effect and is prone to rotation when subjected to external force, causing misalignment between the film and the wind disk, thus affecting the quality of the finished product, and proposes an adjustable wind ring for a film blowing machine.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An adjustable air ring for a film blowing machine, comprising:

[0009] The wind ring body has a plurality of evenly distributed air inlets on its outer wall, an air outlet on its surface, a wind disk rotatably connected to the air outlet, a wind ring fixedly disposed on the surface of the wind disk, and two symmetrical adjustment mechanisms disposed on the surface of the wind disk;

[0010] The adjustment mechanism comprises an adjustment rod slidingly penetrating the surface of the wind disk, a fixing block is fixedly arranged on the outer wall of the bottom end of the adjustment rod, a plurality of limit blocks are fixedly arranged on the surface of the fixing block, and a tension spring is fixedly arranged between the fixing block and the wind disk for pulling the fixing block to reset;

[0011] It also includes a mounting ring, which is arranged below the wind disc. A plurality of ring-shaped and evenly distributed limiting grooves are provided at the bottom of the mounting ring, and the limiting grooves are used in conjunction with the limiting blocks.

[0012] In a possible design, a plurality of support columns are integrally formed at the bottom of the mounting ring, a through mounting hole is opened between the mounting ring and the support columns, a bolt is arranged in the mounting hole, and the bolt is threadedly connected to the air ring body.

[0013] In a possible design, a plurality of circular grooves are provided on the surface of the air ring body for use with the support column, and a threaded groove is provided at the bottom of each of the plurality of circular grooves, and the threaded groove cooperates with the bolt.

[0014] In a possible design, the mounting hole is a countersunk hole.

[0015] In a possible design, the outer walls of the two adjusting rods are integrally formed with positioning blocks, and two positioning grooves are provided in the air disc, and the positioning blocks and the positioning grooves cooperate with each other.

[0016] In a possible design, a spherical groove is provided at the bottom of the two adjusting rods, and a ball is provided in each of the two spherical grooves.

[0017] In the present application, when in use, the fan is connected to the air inlet, and the wind is injected by the fan. The wind enters the inner cavity of the air ring body from the air inlet, and then flows out from the air outlet to inflate the membrane;

[0018] When adjusting the fan disk, press the two adjusting rods downward at the same time to move the fixed block downward, thereby causing the limit block to disengage from the limit slot, and then directly push the adjusting rod to drive the fan disk to rotate, so that the membrane and the center of the wind circle are aligned, then release your hand, and the tension spring pulls the fixed block to reset, so that the limit block and the limit slot are connected, thereby positioning the fan disk.

[0019] Beneficial effects:

[0020] In the utility model, the adjustable film blowing machine air ring can stably position the air disk through the arrangement of multiple structures such as the adjusting rod, the limit block and the limit groove. The air disk can be rotated only by pressing two adjusting rods at the same time, so as to avoid the air disk being rotated by external force, and the adjustment is simple and convenient.

[0021] In the utility model, the adjustable air ring of the film blowing machine can make the ball contact with the air ring body when the pressing force is large through the setting of the ball, which can reduce the resistance of the air disk when it rotates, making it convenient for people to adjust the air disk;

[0022] In the utility model, the fan disk can be stably positioned to prevent the fan disk from rotating due to external force, and the adjustment is simple and convenient. When the pressing force is large, the ball and the wind ring body can be brought into contact, which can reduce the resistance encountered by the fan disk when it rotates, making it convenient for people to adjust the fan disk.
