The cutting edge part at the front part of the cutting knife 20 is flush with the lower end of the guide groove 1806 and is used for a third air cylinder 1809; a slot is formed; the PE tape 17 is cut by the lower end of the guide groove 1806 by the drive of the lower part 19.

As shown in fig. 5 and 6, the main structure of the clamping mechanism 18 on the third lifting platform 8 is the same as that of the clamping mechanism 18 on the first lifting platform 10, and will not be described again. The difference lies in that: on one hand, the guide groove 1806 in the clamping mechanism 18 on the third lifting platform 8 is provided with a slot which is communicated with the slotted hole 1805, and the slot is used for enabling the corresponding guide groove 1806 to be separated from the PE belt 17 which is inserted between the large end plate 103 and the small end plate 101; on the other hand, the third air cylinder 1809 is not provided on the corresponding clamp bracket 1801; a slot is formed; 19 and a corresponding cutter 20.

As shown in fig. 7 and 8, the glue applying mechanism 3 on the second lifting table 9 includes a glue applying bracket 304 fixed on the corresponding horizontal sliding base 11, and the glue applying bracket 304 is sequentially provided with a glue injecting nozzle 301, a hot melting pipe 302, a guide pipe 303 and a fourth air cylinder 305 from left to right. A piston rod of the fourth cylinder 305 concentrically corresponds to the guide tube 303 and is used for pushing the glue stick in the guide tube 303 into the hot melt tube 302, a heating assembly for heating the glue stick to form liquid glue is arranged in the hot melt tube 302, and the glue injection nozzle 301 is connected with the hot melt tube 302 and is used for applying the liquid glue between the slit 109 and the PE tape 17.

The glue coating mechanism 3 on the fourth lifting platform 4 is the same as the glue coating mechanism 3 on the second lifting platform 9, and the description is omitted. The difference lies in that the glue spreading mechanisms 3 on the second lifting platform 9 are horizontally distributed, and the glue spreading mechanisms 3 on the fourth lifting platform 4 are obliquely distributed, so that the glue spreading on the large end plate 103 is facilitated.

The specific implementation method of the embodiment includes the following steps:

1) the first, second, third and fourth elevating tables 10, 9, 8 and 4 are adjusted to the positions shown in fig. 1, so that the guide grooves 1806 of the two clamping mechanisms 18 are respectively located at the upper and lower sides of the same slit 109 on the small end plate 101. The end of the PE tape 17 is manually inserted into the upper guide slot 1806, the second cylinder 1802 of fig. 3 is controlled to extend its piston rod to cause the ram 1804 to compress the PE tape 17, and then the first cylinder 1807 of fig. 3 is controlled to extend its piston rod to cause the ram 1804 to thread the PE through the strip window 1803 to be twisted down. When ram 1804 reaches the lower end of window 1803, the piston rod of second cylinder 1802 is controlled to retract away from PE tape 17, and then first cylinder 1807 is controlled to retract again to the state shown in fig. 3. The above-mentioned operation is repeated until the lower end of the PE tape 17 is twisted to pass through the lower end of the lower guide 1806, and the state shown in fig. 1 is obtained.

2) And controlling the piston rod of the second air cylinder 1802 in the figure 5 to extend to enable the pressing head 1804 to press the PE belt 17. And starting a second motor 13 to drive the third lifting platform 8 to descend, and simultaneously starting a fourth motor on the third lifting platform 8 to drive the corresponding horizontal sliding base 11 to move rightwards, so that the lower guide groove 1806 descends to the position of the large end plate 103 and is in butt joint with the corresponding slit 109. The PE tape 17 is rubbed through the corresponding slit 109 by the method described in step 1).

3) And the fourth motors on the second lifting platform 9 and the fourth lifting platform 4 drive the glue injection mechanisms to translate to the position of the slit 109 penetrating through the PE belt 17, and the glue injection mechanisms respectively cling to glue injection and then drive the two glue injection mechanisms to move reversely to leave the positions. The upper guide groove 1806 is driven to rotate by the first motor 14 to leave the small end plate 101, and is driven by a third air cylinder 1809; a slot is formed; the cutter knife 19 is driven to extend the cutter knife 20 to cut the PE from the lower end of the upper guide groove 1806.

4) The third motor 203 drives the casting mold 1 to rotate for a specific angle, so that the other group of slits 109 corresponds to the upper and lower guide grooves 1806, the first motor 14 and the second motor 13 drive the first lifting platform 10 and the third lifting platform 8, and the two guide grooves 1806 are butted with the slits 109 on the small end plate 101 again.

5) And repeating the tape threading process, threading all the slits 109 on the small end plate 101 and the large end plate 103 through the PE tape 17, and then taking down the casting mold 1 from the driving shaft 201. The tapered sleeve 107 is fastened to the small end plate 101, and the first guide post 105 and the large end plate 103 are fixed to complete the preparation of the casting mold 1, and the slit 109 refractory bricks are further prepared by casting and high-temperature firing.
