A quantitative screw or a quantitative valve for controlling the amount of powder discharged is provided in the discharge pipe 322. The hopper 321 is filled with powder, and the powder is discharged to the inner tube through the discharge pipe 322 connected to the bottom of the hopper 321. The quantitative screw or the quantitative valve is used to control the amount of powder discharged. Since a plurality of discharge pipes 322 are provided, a plurality of inner tubes on the linear track 31 can be filled with powder at the same time.

[0054] like Fig.11The first plugging device 33 includes a plurality of third vacuum suction nozzles 331 that can move up and down and forward and backward, a plug mold 332 arranged on one side of the linear track 31, and a plug feeding channel 333 arranged on one side of the plug mold 332. The plug mold 332 can move left and right. A plurality of third openings 3321 are provided on the side of the plug mold 332 close to the plug feeding channel 333. The plurality of third vacuum suction nozzles 331 move down from the top of the plug mold 332 to overlap with the plurality of third openings 3321 and absorb the plugs, then start to move up, move forward to the top of the linear track 31, move down to overlap with the inner tube, then start to move up, and then move backward to the top of the plug mold 332. The third vacuum suction nozzle 331 is used to absorb the plugs. The plurality of third vacuum suction nozzles 331 can absorb a plurality of plugs at the same time. The plug mold 332 is used to transfer the plugs in batches.

[0055] It should be noted that the forward and backward movement and the left and right movement are relative to the linear track 31. Fig. 9 and Fig.11 As shown, the rear side is the side of the linear track 31 close to the plug mold 332, the side of the linear track 31 relative to the plug mold 332 is called the front side, the side of the linear track 31 close to the first conveying track 2 is the left side, and the side of the linear track 31 away from the first conveying track 2 is the right side; the plug feeding channel 333 is responsible for conveying the plug to the plug mold 332, and the initial position of the plug mold 332 is as shown in FIG. Fig.11 As shown, while the plug mold 332 moves to the right, the plugs enter the multiple third openings 3321 of the plug mold 332 one by one from the outlet of the plug feeding channel 333 until all the third openings 3321 are loaded with plugs, and then the multiple third vacuum suction nozzles 331 start to move downward from the top of the plug mold 332 until they overlap with the multiple third openings 3321 and suck up the multiple plugs at the same time, and then the multiple third vacuum suction nozzles 331 move forward with the plugs to the top of the linear track 31, and at the same time the plug mold 332 moves to the left to the initial position and then moves to the right again to allow the next batch of plugs to enter the plug mold 332, and then the multiple third vacuum suction nozzles 331 move downward again. The plug is pressed into the inner tube on the linear track 31, and at the same time, the plurality of third vacuum nozzles 331 stop sucking the plug so that the third vacuum nozzles 331 are separated from the plug. Finally, the plurality of third vacuum nozzles 331 first move upward and then move backward to the top of the plug mold 332. At this time, the third vacuum nozzle 331 enters the next cycle to ensure continuous plugging. The circulation route of the third vacuum nozzle 331 is: it moves downward from the top of the plug mold 332 to overlap with the plurality of third openings 3321 and suck the plug, then starts to move upward, then moves forward to the top of the linear track 31, then moves downward to overlap with the inner tube, then starts to move upward, and then moves backward to the top of the plug mold 332. Among them, the third vacuum nozzle 331 can be driven by a cylinder or other mechanism to achieve up and down movement and forward and backward movement.

[0056] Preferably, a retaining plate 34 that can move left and right and front and back is provided on the other side of the linear track 31 relative to the plug mold 332, and a plurality of fourth openings 341 are provided on the side of the retaining plate 34 close to the linear track 31. After the retaining plate 34 moves backward to overlap with the linear track 31 so that the bottom cover is inserted into the fourth openings 341, it moves rightward to drive the bottom cover to move rightward along the linear track 31. The retaining plate 34 is driven by a cylinder or other mechanism to realize the up-down movement and left-right movement. The fourth opening 341 is used to insert the bottom cover with the inner tube pressed thereon. When the positioning plate 34 moves forward and backward, the bottom cover with the inner tube pressed thereon can enter or leave the fourth opening 341. When the positioning plate 34 moves backward to a position overlapping with the linear track 31, the bottom cover with the inner tube pressed thereon enters the fourth opening 341. When the positioning plate 34 moves forward, the bottom cover with the inner tube pressed thereon leaves the fourth opening 341 and separates from the positioning plate 34. When the positioning plate 34 moves left and right at a position overlapping with the linear track 31, the bottom cover with the inner tube pressed thereon can move left and right with the positioning plate 34. When the overlapping position of the linear track 31 moves to the right, multiple bottom covers with pressed inner tubes on the linear track 31 can be moved simultaneously. Therefore, preferably, the number of the fourth openings 341 on the positioning plate 34 is 2 to 8 times the number of the feeding tubes 322, and the multiple here is an integer multiple. The positioning plate 34 moves along the following route to improve the efficiency of powder filling and plugging: the initial position of the positioning plate 34 is the position where the left end of the positioning plate 34 is closest to the left end of the linear track 31 and the fourth opening 341 of the positioning plate 34 is not inserted into the bottom cover with pressed inner tubes. The positioning plate 34 moves backward from the initial position to the position where the fourth opening 341 of the positioning plate 34 is closest to the left end of the linear track 31 and the bottom cover with pressed inner tubes is not inserted. Fig. 9 The position where the positioning plate 34 overlaps with the linear track 31 allows the bottom cover with the inner tube pressed thereon to enter the fourth opening 341, as shown in FIG. Fig. 9 The position shown is defined as the first position, and then the positioning plate 34 moves a fixed distance to the right to the second position, dragging all the bottom covers with inner tubes pressed on the linear track 31 to move to the right. The fixed distance can be set according to the number of feeding tubes 322. If the number of feeding tubes 322 is 6, the fixed distance to the right is the distance of 6 fourth openings 341. When the positioning plate 34 moves a fixed distance to the right once, a part of the bottom covers with inner tubes pressed arrives under the powder filling device 32, and the bottom covers originally located under the powder filling device 32 are moved to the bottom of the first pressing device 33, and the bottom covers originally located under the first pressing device 33 are moved out, and then the positioning plate 34 moves forward to separate the bottom covers with inner tubes pressed from the positioning plate 34. This position is called the third position, and then the positioning plate 34 moves to the left from the third position back to the initial position. The positioning plate 34 repeatedly moves along the route of the initial position - the first position - the second position - the third position, and can transport the bottom caps pressed with the inner tubes along the linear track 31 in batches. Moreover, the positioning plate 34 has a short stroke, which is conducive to speeding up the powder filling and plugging speed, thereby improving the assembly efficiency of the bottle caps.

[0057] Preferably, see Fig.10 The powder filling device 32 also includes a sliding plate 323 that can move up and down. The sliding plate 323 is provided with a plurality of through-tube holes 3231. The through-tube holes 3231 correspond to the feeding tube 322 one by one. The middle of the feeding tube 322 passes through the through-tube holes 3231. After the powder filling is completed, the sliding plate 323 moves downward until the bottom surface of the sliding plate 323 abuts against the top surface of the inner tube. Then, the bottom cover pressed with the inner tube moves to the right along the linear track 31. During the process of the bottom cover pressed with the inner tube moving to the right, the sliding plate 323 can scrape out the powder that exceeds the top surface of the inner tube to avoid affecting the subsequent plugging process. The sliding plate 323 can be driven by a cylinder or other mechanism to move up and down.

[0058] Preferably, see Fig.11 and Fig.12 The powder filling plugging machine 3 also includes a second plugging device 35. The powder filling device 32, the first plugging device 33 and the second plugging device 35 are arranged on the linear track 31 in sequence. The second plugging device 35 is used to pressurize the plug for the second time to ensure that the plug can be pressed into the inner tube in place. The second plugging device 35 includes a pressing plate 351 that can move up and down, and the pressing plate 351 is located above the linear track 31. When the pressing plate 351 moves downward, it can apply pressure to the plug so that the plug is pressed against the inner tube; in the powder filling plugging machine 3, when the third vacuum suction nozzle 331 of the first plugging device 33 carries the plug and moves downward above the inner tube, it can press the plug against the inner tube. When the pressing plate 351 of the second plugging device 35 moves downward, it pressurizes the plug again to ensure that the plug can be pressed into the inner tube in place. Among them, the pressing plate 351 can be driven by a cylinder or other mechanism to achieve up and down movement. Optionally, one or more pressing plates 351 may be provided; when one is provided, the projection area of ​​the pressing plate 351 should be able to cover all semi-finished bottle caps of a single batch; when multiple are provided, the pressing plates 351 correspond one to one with the semi-finished bottle caps.

[0059] Preferably, see Figure 2The assembly line of the ready-made beverage bottle caps also includes a visual inspection machine 6 for inspecting finished products and an electrostatic dust collector 7 for removing dust from the surface of finished products. The visual inspection machine 6 is arranged at the exit position of the finished product channel 57, and the electrostatic dust collector 7 is arranged at the exit position of the visual inspection machine 6. The finished products pass through the visual inspection machine 6, the electrostatic dust collector 7 and the packaging machine 8 in sequence. The visual inspection machine 6 inspects the assembly effect, and the unqualified bottle caps are quickly removed. The electrostatic dust collector 7 removes the static electricity of the bottle caps and the excess powder and dust on the surface; in this embodiment, the visual inspection machine 6 can adopt the same structure as the bottle cap visual inspection machine of patent CN210753848U, and the electrostatic dust collector 7 can adopt the same structure as the bottle cap electrostatic dust collector of patent CN211359886U, which will not be repeated here; the assembly line of the ready-made beverage bottle caps can also be provided with a packaging machine 8 for finished product packaging, and the bottle caps coming out of the electrostatic dust collector 7 are automatically boxed by the packaging machine 8 to achieve fully automated production.

[0060] In this embodiment, a reversing mechanism that can flip the bottom cover upside down by 180° is provided on the first conveying track 2, so that the bottom cover coming out of the first press 1 can be turned upside down. Since the inner tube is pressed on the bottom cover, the inner tube on the bottom cover is also turned upside down, which is suitable for the inner tube with the powder inlet located at the top, so that the powder inlet of the inner tube faces upward, which is convenient for powder filling. Optionally, the reversing mechanism includes a channel composed of multiple round steels extending along the travel direction of the bottom cover, and the multiple round steels are twisted so that the bottom cover pressed with the inner tube passing through the channel can be turned upside down by 180° to achieve reversal.
