When the original machine rotating piece 12 rotates, the shaft end adapter 33 is driven to rotate, the cam follower 32 is further driven to rotate, and the encoder end adapter 31 is connected in parallel to rotate, so that the encoder assembly 20 acquires phase information. Thus, even if the control system of the original machine member 10 is closed, the phase information of the original machine rotating member 12 cannot be directly acquired, and the encoder assembly 20 can also indirectly acquire the phase information of the original machine rotating member 12.

Further, as shown in fig. 3, the encoder assembly 20 includes an encoder 21, an encoder mounting plate 22 and an encoder connecting plate 23, where the encoder 21 is detachably connected to the encoder mounting plate 22, at least one first bar hole 221 is formed on the encoder mounting plate 22, a first connecting hole 231 corresponding to the first bar hole 221 is formed on the encoder connecting plate 23, and a detachable first connecting piece is disposed between the first bar hole 221 and the first connecting hole 231; at least one second bar-shaped hole 232 is formed in the encoder connecting plate 23; the original equipment 11 is provided with a second connecting hole 111 corresponding to the second strip-shaped hole 232, and a detachable second connecting piece is arranged between the second strip-shaped hole 232 and the second connecting hole 111; the first bar hole 221 and the second bar hole 232 are vertically arranged, and optionally, the first bar hole 221 and the second bar hole 232 are respectively horizontally arranged and vertically arranged, so that a detachable connecting piece has enough space in the bar holes to move and adjust, and the two degrees of freedom of the encoder 21 can be adjusted up and down and left and right.

Optionally, the detachable connection mode has various advantages of convenient detachment, easy maintenance, cost saving and the like, and the detachable connection mode can be detached and assembled without damaging the connecting piece, and generally adopts threaded connection, snap connection, bolt connection, spring connection and the like.

The through hole 311 in this embodiment may be a kidney-shaped hole, where the kidney-shaped hole is firstly a through hole, and secondly two ends of the kidney-shaped hole are semicircular arcs, and the middle is a parallel plane, and when each component is assembled, the positions of some parts are difficult to achieve an ideal position or the positions between the parts need to be adjusted, and generally, the kidney-shaped hole is designed.

As shown in fig. 5 and 6, the cam follower 32 includes a follower body 321 and a sleeve 322, the sleeve 322 is sleeved outside one end of the follower body 321, the other end of the follower body 321 is provided with a threaded end 323, and one end of the follower body 321 sleeved with the sleeve 322 extends into the through hole 311, so that the sleeve 322 slides in the through hole 311.

The cam follower 32 is a mechanical motion transmission device, and is widely applied to various production equipment such as packaging machines, hydraulic machines, plastic injection molding machines and the like. The cam operates on the principle that the movement of the other mechanical elements is driven by the rotation of the cam. The shape and the size of the cam can be designed according to different spin balls, so that different movement modes and movement tracks are realized. The cam follower 32 has stable motion, high precision, high reliability, long service life and large bearing capacity, and is mostly used in a process of needing a stable power transmission when moving at a high speed.

Further, as shown in fig. 7 and 8, one end of the shaft end adapter 33 is provided with a threaded hole 333, and the threaded end 323 of the follower body 321 is connected to the threaded hole 333, so that the encoder 21 and the original machine rotating member 12 can be connected.

Because the encoder 21 is hard to ensure coaxiality with the original machine rotating part 12, the eccentric structure does not require coaxiality, and can also meet the requirement that the original machine element 10 drives the encoder 21 to rotate, so that the encoder 21 is convenient to cooperate with the original machine element 10 and is convenient to install.

Further, as shown in fig. 9 and 10, one end of the encoder 21 is provided with a locking ring 211, and the first protrusion 313 is inserted into the locking ring 211.

When the locking member 2114 is unlocked, the opening 2111 becomes larger, and the first protrusion 313 can be released.

In this embodiment, the first protruding portion 313 is locked by not only providing a notch to use a locking member, but also screw locking and eccentric locking: the inclined locking, the four-bar mechanism locking, etc., can firmly attach the first boss 313 to the encoder 21.
