Description

Technical Field

[0001] This utility model relates to the field of air shaft technology, specifically an axially adjustable air shaft. Background Technology

[0002] For example, a patent publication number CN218201317U discloses an axially adjustable air shaft, which includes a housing, a drive shaft, and an adjustment mechanism. The housing has a shaft hole that extends through both ends of the housing. A portion of the drive shaft is inserted into the shaft hole from the first end of the shaft hole. The adjustment mechanism includes an adjustment shaft and an adjustment sleeve. One end of the adjustment shaft is rotatably connected to the end of the drive shaft located in the shaft hole, and the other end of the adjustment shaft extends out from the second end of the shaft hole. The adjustment sleeve is rotatably disposed in the shaft hole, and one end of the adjustment sleeve extends out from the second end of the shaft hole. The adjustment sleeve has an adjustment hole with an internal thread on its wall. The adjustment shaft passes through the adjustment sleeve, and the outer wall of the adjustment shaft has an external thread. The external thread on the adjustment shaft engages with the internal thread of the adjustment hole. By rotating the adjustment shaft, the adjustment sleeve can be moved axially on the drive shaft, thereby adjusting the packaging film roll to the normal position on the air shaft and achieving timely correction of the packaging film.

[0003] However, during the use of the above-mentioned equipment, due to the design of its internal casing and drive shaft, when correcting the packaging film, the operator needs to hold the outer wall of the air shaft and rotate it to control the position adjustment of the air shaft on the outer wall of the rotating shaft. When the operator exerts force to rotate, the part of the packaging film already wrapped around the outer wall of the air shaft is easily twisted, resulting in wrinkles in the packaging film and rendering it unusable. This reduces the axial adjustment performance of the air shaft and affects its normal use. Therefore, in order to address this issue, we propose a more convenient and practical air shaft that meets the usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide an axially adjustable air shaft to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an axially adjustable air shaft, including a mounting mechanism for fixed setting, the mounting mechanism including a fixing frame, through holes on both sides of the fixing frame, a first control rod screwed into the through holes, a clamping plate rotatably connected to one end of the first control rod, an adjustment mechanism provided on one side of the mounting mechanism for adjusting the axial direction, the adjustment mechanism including an adjustment component and an inner shaft, an air shaft body fixedly connected to the outer wall of the inner shaft, rotating plates fixedly connected to both sides of the inner shaft, and a mounting plate provided on one side of the rotating plates.

[0006] Furthermore, a fixing plate is fixedly connected to the top center of the fixing frame, and a slot is opened in the top center of the fixing plate, with a sliding block slidably connected inside the slot.

[0007] Furthermore, a through hole is provided on one side of the fixed plate, and a first lead screw is rotatably connected in the through hole. The first lead screw is screwed to a sliding block. A servo motor is installed on one side of the fixed plate, and the output end of the servo motor is connected to the first lead screw.

[0008] Furthermore, the adjustment component includes an adjustment frame connected to a sliding block, and a lifting block is slidably connected to the inner wall of one side of the adjustment frame.

[0009] Furthermore, a through hole is provided at the center of the top of the adjustment frame, and a second lead screw is screwed into the through hole. One end of the second lead screw is rotatably connected to the lifting block, and the other end is fixedly connected to a control ring.

[0010] Furthermore, a through hole is provided on one side of the lifting block, and a third lead screw is slidably connected to the through hole. A rotating ring is rotatably connected to one side of the lifting block, and the rotating ring is screwed to the third lead screw. A connecting ring is rotatably connected to one end of the third lead screw, and one side of the connecting ring is connected to the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This axially adjustable air shaft, through the installation and adjustment mechanisms, first connects the rotating plate and the mounting plate using bolts and other connectors. Then, manually rotating the control ring drives the second lead screw to rotate, causing the lifting block to move along the adjustment frame. Next, manually controlling the rotating ring drives the third lead screw. Under the action of the connecting ring, the movement of the rotating plate and the mounting plate causes the inner shaft and the air shaft body to move, adjusting the axial direction. This device can adjust the position to meet the usage requirements of the air shaft, improving the axial adjustment performance of the air shaft, ensuring the normal use of the air shaft, and is highly practical and suitable for widespread application.

[0013] Meanwhile, the installation mechanism can easily adjust the position of the air shaft to adapt to different production needs, ensuring that the air shaft is stable and reliable after installation and is not easy to loosen. Attached Figure Description

Before using this equipment, a thorough inspection should be conducted to ensure that all components are securely installed and free from looseness or damage. When adjusting the axial position of the air shaft, it should be adjusted appropriately according to the thickness and width of the packaging film to avoid excessive tension or slack, which could affect the flatness and stability of the packaging film. Simultaneously, the operator should be familiar with the working principle of the adjustment mechanism 2 to ensure accurate and rapid adjustment.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: an axially adjustable air shaft, including a mounting mechanism 1 for fixed setting. The mounting mechanism 1 includes a fixing frame 101, with through holes on both sides of the fixing frame 101. A first control rod 102 is screwed into the through holes.

[0022] It should be noted that during use, firstly, the fixing frame 101 is placed on the connector, then the first control lever 102 is manually rotated to drive the clamping plate 103 for fixing, then the servo motor 107 drives the first lead screw 106 to make the sliding block 105 move along the fixing plate 104 to adjust the position of the air shaft. The installation mechanism 1 can easily adjust the position of the air shaft to adapt to different production needs and ensure that the air shaft is stable and reliable after installation and is not easy to loosen.

[0023] like Figure 3 As shown, the adjustment assembly includes an adjustment frame 201, which is connected to a sliding block 105. A lifting block 202 is slidably connected to the inner wall of one side of the adjustment frame 201. A through hole is opened in the center of the top of the adjustment frame 201, and a second lead screw 203 is screwed into the through hole.

Under the action of the connecting ring 207, the inner shaft 3 and the air shaft body 4 move through the movement of the rotating plate 209 and the mounting plate 208, adjusting the axial direction. The adjusting mechanism 2 has a precise axial adjustment function and a convenient operation method, so it can adapt to air shafts of different specifications and types, as well as different production environments and needs.

[0025] During use, the sliding block 105 and the adjusting frame 201 are connected, and the rotating plate 209 and the mounting plate 208 are connected.

Next, the servo motor 107 drives the first lead screw 106 to make the sliding block 105 move along the fixed plate 104. The control ring 204 is manually rotated to drive the second lead screw 203 to rotate and make the lifting block 202 move along the adjusting frame 201. Then, the rotating ring 206 is manually controlled to drive the third lead screw 205 to move. Under the action of the connecting ring 207, the inner shaft 3 and the air shaft body 4 move through the movement of the rotating plate 209 and the mounting plate 208 to adjust the axial direction.
