[0001] The utility model belongs to spinning apparatus technical field, concretely relates to a ring blow -off box alignment detection device. BACKGROUND

[0002] In actual production, the process of changing the side blow -off spinning box on the production line into the ring blow -off spinning box often encounters the phenomenon that the ring blow -off cylinder and the spinning assembly cannot be precisely aligned after installation, which will greatly affect the cooling effect of the yarn. The main reasons for this problem are as follows:

[0003] Equipment aging problem: due to the long service life of the ring blow -off box equipment, part of the structure may deform, resulting in that precise alignment cannot be achieved after installation.

[0004] Non-standard operation problem: the maintenance installation personnel did not strictly operate according to the requirements during the installation process, resulting in that the slot of the blow -off box and the assembly cannot be aligned.

[0005] The existing method for confirming whether the alignment is correct is to view the spinning assembly from the bottom of the ring blow -off box, and to observe the alignment by the naked eye, but this method has many problems: first, the spinning assembly still contains high-temperature melt after the metering pump is closed, which may drop due to gravity, which will cause great safety hazards to the person observing from the top; second, the naked eye observation is easily affected by light, angle and other factors, and it is difficult to completely and accurately judge the alignment, which often leads to errors.

[0006] Therefore, it is necessary to propose a safe, fast and efficient detection device to solve the above problems. UTILITY MODEL CONTENTS
