The utility model has the following working principle:

The outer cap is spirally and vibrationally fed from the outer cap vibration feeding disc 1 to one end of the outer cap positioning feeding track 21, the outer cap is blocked by left and right discharging stop blocks 23 of the outer cap positioning feeding track 21 under the action of spring force of discharging springs 24, whether the outer cap is in place or not is detected by a first optical fiber sensor, then a stirring rod 222 of a stirring multi-shaft moving assembly 221 installed on the outer cap stirring mechanism 22 moves downwards, the lower end of the stirring rod 222 is inserted into the inner wall of the outer cap, the stirring multi-shaft moving assembly 221 drives the stirring rod 222 to move from one end of the outer cap positioning feeding track 21 to the other end, the stirring rod 222 stops after passing through the discharging stop blocks 23 and moves an equidistant position, and then the stirring multi-shaft moving assembly 221 resets, so that the stirring rod 222 resets to an initial position.

After the outer caps are placed on the outer cap positioning and feeding track 21 at equal intervals, the shifting fork moving assembly 41 drives the shifting fork plate 42 to approach the outer caps on the outer cap positioning and feeding track 21, so that the accommodating groove 421 on the shifting fork plate 42 is inserted into the outer cap upper end shape, then the shifting fork moving assembly 41 drives the shifting fork plate 42 to advance towards the other end of the outer cap positioning and feeding track 21, so that the outer caps on the outer cap positioning and feeding track 21 reach the detection point of the first optical fiber sensor 63, the first optical fiber sensor 63 detects whether paper pads exist at the bottom of the inner wall of the outer caps, and if no paper pads exist, the outer caps are judged to be defective products, and the defective outer cap discharging device 6 designed at the rear end position in the outer cap positioning and feeding track 21 is used for discharging. Then the shifting fork moves the assembly 41 to reset the shifting fork plate 42 and return to the initial position, and the actions are repeated in such a way that the outer caps are sequentially shifted until the outer cap positioning and feeding track 21 is fully filled, the outer cap baffle 25 is arranged at the other end of the outer cap positioning and feeding track 21 to limit, and the second optical fiber sensor detects whether the outer caps are in shortage or not, if the outer caps are detected, all actions of the front end are suspended (namely, the outer caps on the outer cap positioning and feeding track 21 are stopped to move), and if the outer caps are in shortage caused by the fact that the outer caps are defective after being discharged, the outer caps continue to operate until the second optical fiber sensor detects the shortage of the outer caps.

After the outer cap reaches the other end position of the outer cap positioning and feeding track 21, the material taking multi-shaft moving assembly 31 on the outer cap material taking device 3 drives the expansion shaft 32 to enable the lower end position of the expansion shaft 32 to be inserted into the inner wall of the outer cap, then the expansion shaft driving piece 33 drives the inner core expansion rod to move upwards, so that the outer cylinder is expanded, the inner wall of the outer cap is simultaneously tensioned, then the material taking multi-shaft moving assembly 31 drives the expansion shaft 32 to clamp the outer cap to move upwards and move to the position right above the outer cap assembling lower ejector rod of the outer cap pressing device 5, then the material taking multi-shaft moving assembly 31 drives the expansion shaft 32 to move downwards, so that the outer cap is directly inserted into the filling hole on the outer cap assembling lower ejector rod 521, the inner core expansion rod is moved downwards by the expansion shaft driving piece 33, so that the outer cylinder is reset and contracted to be separated from the outer cap, and then the material taking multi-shaft moving assembly 31 enables the expansion shaft 32 to return to the original position.

When the porcelain tube of the fuse clamped by the clamp of the turntable enters the outer cap pressing device 5 (the structure of the turntable can be seen in patent content of publication No. CN210837615U, which is not expanded in detail), the outer cap is put into the filling hole of the outer cap assembly lower mandril 521 of the outer cap pressing device 5, and the horizontal driving member 525 installed on the outer cap pressing device 5 drives the displacement seat 524 to advance towards the porcelain tube, so that the outer cap assembly lower mandril 521 reaches the position right under the porcelain tube of the fuse on the clamp of the turntable, and the positioning work is performed by the limiting block 527. Then, the cap pressing driving member 522 moves up to drive the outer cap assembling jack to move upwards, so that the outer cap assembling jack jacks up the outer cap assembling lower jack 521 to move upwards, and the proximity clamp is used for detecting whether the outer cap assembling jack works in place, then the outer cap in the filling hole of the outer cap assembling lower jack 521 is jacked into the lower end (one end) position of the porcelain tube, meanwhile, the upper end (two ends) surface of the porcelain tube is propped against the lower end working surface of the outer cap assembling upper jack 512, after the pressure sensor 513 installed on the outer cap assembling upper jack 512 monitors the pressure value, and the displacement sensor 514 resets with the displacement obtained by the displacement detection block on the outer cap assembling lower jack 521, so that the outer cap assembling lower jack 521 moves down to reset, and the horizontal moving member drives the displacement seat 524 to reset, so that the outer cap assembling lower jack 521 returns to the initial position, and one end outer cap pressing assembling work is completed. In this cycle.
