Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic shafts, in particular to a novel pneumatic shaft sleeve. Background Art

[0002] An air expansion shaft is a device used to wind or unwind coils. It uses the principle of air pressure to provide support and fastening for the roll. The air expansion shaft usually consists of a hollow metal shaft and two closed end covers. There are multiple air vents inside the shaft. When using the air expansion shaft, the shaft is inserted into the inner diameter of the coil and the air pressure is transmitted to the inside of the shaft through the air source. When the air pressure increases, the shaft will expand, so that the coil is tightly fixed on the shaft.

[0003] When the operator of the existing pneumatic shaft clamps the material tube, the material tube is likely to be not clamped in place, resulting in deviation in the material winding and affecting the subsequent use of the material. For this reason, we propose a new pneumatic shaft sleeve. Utility Model Content

[0004] The utility model aims to provide a novel pneumatic shaft sleeve to achieve the effect of limiting the clamping of a material tube, so as to solve the problem that when the operator of the existing pneumatic shaft clamps the material tube, the material tube is likely to be not clamped in place, resulting in deviation in the material winding and affecting the subsequent use of the material.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of pneumatic shaft sleeve, comprising a sleeve and a side seat, wherein a side seat is installed on one side of the sleeve, an adjusting disk is installed on one side of the side seat through a sliding column, an extrusion disk is installed on one side of the adjusting disk through a supporting column, a spring is installed on the inside of the adjusting disk at one side of the supporting column through a spring groove, a proximity switch is installed inside the spring groove, and a control box is installed on one side of the side seat near the bottom.

[0006] Preferably, a controller is installed at the bottom of the control box, an alarm is installed at the top of the control box, and the alarm is electrically connected to the proximity switch.

[0007] Preferably, a movable column is installed on one side of the adjustment disk near the top, and the movable column is inserted into the side seat.

[0008] Preferably, an adjusting column is installed on one side of the side seat at the position of the moving column, the adjusting column is sleeved inside the moving column, and the adjusting column is screwed together with the moving column via a thread.

[0009] Preferably, a clamping groove is provided on the outer surface of the sleeve, a positioning frame is installed inside the clamping groove, an inner groove is provided on the top of the positioning frame, and bearings are installed on both sides of the inner groove through positioning shafts.

[0010] Preferably, there are sixteen positioning frames in total, and the sixteen positioning frames are equally divided into four groups, and the four groups of positioning frames are evenly distributed on the outer surface of the sleeve.

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

[0012] 1. The utility model achieves the effect of limiting the clamping of the material tube by arranging an extrusion disk, an adjustment disk, a support column and a proximity switch. The adjustment disk is arranged on one side of the side seat through a sliding column, the extrusion disk is arranged on one side of the adjusting disk through a support column, a spring is arranged on one side of the support column through a spring groove inside the adjusting disk, and a proximity switch is arranged inside the spring groove to solve the problem that when the operator of the existing pneumatic shaft clamps the material tube, the material tube is likely to be not clamped in place, resulting in deviation in the material winding and affecting the subsequent use of the material, thereby ensuring the clamping effect of the material tube and thus ensuring the normal winding of the material.

[0013] 2. The utility model achieves the effect of conveniently adjusting the clamping position of the material pipe by arranging an adjusting column, an adjusting disk and a moving column. The moving column is arranged near the top on one side of the adjusting disk, and the moving column is inserted into the inside of the side seat. An adjusting column is arranged on one side of the side seat at the position of the moving column, and the adjusting column is sleeved inside the moving column. The adjusting column and the moving column are screwed together by threads to solve the problem that the positioning and clamping position of the existing material pipe is fixed, material pipes of different lengths cannot be positioned and installed, and the applicability of the pneumatic shaft is poor. It is convenient to position and clamp material pipes of different lengths, thereby ensuring the applicability of the pneumatic shaft.

[0014] 3. The utility model achieves the effect of facilitating the unloading of the material pipe by setting a positioning frame and a bearing. A clamping groove is provided on the outer surface of the sleeve, a positioning frame is provided inside the clamping groove, an inner groove is provided on the top of the positioning frame, and bearings are provided on both sides of the inner groove through the positioning shaft to solve the problem that during the use of the existing pneumatic shaft, the material is heavy after being wound for a period of time, and the material unloading convenience of the material pipe is not good, thereby improving the unloading convenience of the pneumatic shaft.
