[0045] Referring to Figure 1 , Figure 6 and Figure 7 , the bottle cap conveying assembly 21 comprises two parallelly arranged bottle cap conveying belts 211; the bottle cap conveying belt 211 is axially and horizontally arranged, and the two bottle cap conveying belts 211 are supported above the first bottle body conveying belt 11 by the support; a gap is left between the two bottle cap conveying belts 211 for the feeding end 52 and the tube 53 of the push type bottle cap 5 to pass through. The conveying ends of the two cap bodies 51 cooperate to overlap the bottom end of the cap body 51 of the push type bottle cap 5 and convey the push type bottle cap 5. When the cap body 51 is conveyed, the feeding end 52 and the tube 53 of the push type bottle cap 5 are placed in the gap between the two bottle cap conveying belts 211 and the bottom end of the cap body 51 is overlapped on the two bottle cap conveying belts 211, so that the push type bottle cap 5 can be conveyed by the two bottle cap conveying belts 211.

The two limiting side bars 2111 cooperate with the limiting top bar 2112 to limit the cap body 51 conveyed by the two bottle cap conveying belts 211, so as to limit the swinging of the cap body 51 during the conveying process.

[0047] Referring to Figure 1 , Figure 6 and Figure 8 , the output end of the bottle cap conveying assembly 21 is further provided with a transfer part, which includes two parallel cap supporting plates 212 connected to the output ends of the two bottle cap conveying belts 211, and a gap is left between the two cap supporting plates 212 for the feeding end 52 and the tube 53 of the press-type bottle cap 5 to pass through. The two cap supporting plates 212 cooperate to support the bottom end of the cap body 51 of the press-type bottle cap 5. The press-type bottle cap 5 conveyed by the two bottle cap conveying belts 211 can be transferred to the two cap supporting plates 212.

[0048] Referring to Figure 1 , Figure 6 and Figure 8 , the bottle cap spacing assembly 22 includes two parallel spacing conveying belts 221, which are vertically arranged in the axial direction and are supported on the frame by supports. The two spacing conveying belts 221 leave a gap between them for the feeding tube 53 and the tube 53 of the press-type bottle cap 5 to pass through. The input ends of the two spacing conveying belts 221 respectively extend below the two cap supporting plates 212. The conveying directions of the two spacing conveying belts 221 are oppositely arranged. The annular belt of the spacing conveying belt 221 is uniformly connected with a plurality of clamping blocks 222, and a limiting notch is formed on the side of the clamping block 222 away from the annular belt, which is used for embedding the bottom feeding end 52 of the cap body 51. The clamping blocks 222 on the two spacing conveying belts 221 are arranged one by one. When the clamping blocks 222 of the two spacing conveying belts 221 move to the bottom of the two cap supporting plates 212, the corresponding clamping blocks 222 of the two spacing conveying belts 221 cooperate to clamp the feeding end 52 of the cap body 51 on the transfer part, and convey the cap body 51 to the gap between the two spacing conveying belts 221.

[0049] Through the above setting, the two interval conveying belts 221 cooperate with the corresponding clamping blocks 222 to clamp and convey the pressed bottle caps 5 in the transfer part, and the clamping blocks 222 make the pressed bottle caps 5 conveyed subsequently to the interval between the two interval conveying belts 221 at a certain distance, so that the cap body 51 is better gripped by the cap screwing part 33, and the adjacent pressed bottle caps 5 are limited from abutting against each other, and the situation that the electrically rotating clamping jaw 333 of the cap screwing part 33 grabs the pressed bottle cap 5 is affected. The limiting notches outside the clamping blocks 222 are arranged to facilitate the corresponding clamping blocks on the two interval conveying belts 221 to clamp the feeding end 52 of the cap body 51 more stably.

The limiting spring 2133 is arranged higher than the limiting top blocking strip 2112. When the cap body 51 of the pressed bottle cap 5 is overlapped on the two cap supporting plates 212 of the transfer part, the two blocking blocks 2131 are arranged oppositely with the cap body 51.

[0051] The cap body 51 of the pressed bottle cap 5 conveyed out subsequently via the two bottle cap conveying belts 211 can abut against the two limiting blocking blocks 2131, on the one hand, the cap body 51 can be prevented from being pushed out of the transfer part by the cap body 51 conveyed subsequently, and on the other hand, the cap body 51 can be positioned by the two blocking blocks 2131, so that the corresponding blocking blocks 2131 of the two interval conveying belts 221 can clamp and convey the feeding end 52 of the cap body 51 more accurately.

When the lifting driving part 32 of the cap screwing mechanism 3 cooperates with the transverse driving part 34 to drive the cap screwing part 33 to drive the cap body 51 and the bottom end of the pipe 53 to be inserted into the bottle mouth of the bottle, the clamping jaw cylinder 353 drives the two straightening plates 354 to move away from each other, so that the cap body 51 can be smoothly inserted into the bottle mouth end.
