When the outer conical surface of the valve core 232 fits with the inner conical surface of the valve seat 231, the glue cavity 233 and the glue pump are connected. The outlet 2311 is closed, and the glue in the glue chamber 233 cannot be sprayed onto the bottom plug 20 through the outlet 2311. When the outer cone surface of the valve core 232 and the inner cone surface of the valve seat 231 are separated, the glue chamber 233 is connected to the outlet 2311, and the glue pump is connected to the glue chamber 233 through the rubber hose 2331, and can pump glue into the glue chamber 233 through the rubber hose 2331, and can generate pressure in the glue chamber 233, so that the glue in the glue chamber 233 can pass through the gap between the outer cone surface of the valve core 232 and the inner cone surface of the valve seat 231 and spray out through the outlet 2311. This structure realizes the gluing process of the bottom plug 20 by the valve core 232 sliding back and forth in the valve seat 231.

[0057] Furthermore, the first glue-applying component 23 also includes a glue-applying fixed seat, a sliding member 234, a first elastic member 235 and a second elastic member 236. The sliding member 234 is slidably arranged on the glue-applying fixed seat, an annular boss 2321 is arranged on the outer peripheral surface of the valve core 232, the sliding member 234 is sleeved on the valve core 232 and can abut against one end surface of the annular boss 2321, the glue-applying fixed seat is provided with a spring pressure plate 237, the second elastic member 236 is sleeved on the valve core 232 and abuts against the other end surface of the annular boss 2321 and between the spring pressure plate 237, the glue-applying fixed seat is also provided with a spring seat 238, and the two ends of the first elastic member 235 are connected between the spring seat 238 and the sliding member 234; the bottom plug transmission component 21 is provided with a protrusion 2121, and the protrusion 2121 The number of settings matches the number of installation slots. When the plug-in transfer disc 211 of the bottom plug transfer component 21 rotates, the protrusion 2121 abuts against the sliding member 234. The sliding member 234 drives the valve core 232 to slide in the valve seat 231 through the annular boss 2321 to overcome the elastic force of the second elastic member 236, so that the glue chamber 233 and the outlet 2311 are connected. When the protrusion 2121 is separated from the sliding member 234, the first elastic member 235 can return the sliding member 234, and the second elastic member 236 can slide the valve core 232 in the valve seat 231 to close the glue chamber 233 and the outlet 2311. This structure realizes that the plug-in transfer disc 211 can automatically control the injection of glue when it rotates, and the matching is accurate. In this embodiment, the first elastic member 235 is a tension spring, and the second elastic member 236 is a compression spring.

[0058] Specifically, the sliding member 234 includes a vertically connected crossbar 2341 and a vertical bar 2342, the end of the crossbar 2341 away from the vertical bar 2342 is provided with an abutment portion 2341a, the glue application fixed seat is also provided with a guide sleeve 239 and a sliding seat 230, the crossbar 2341 is slidably arranged in the guide sleeve 239, the upper end of the vertical bar 2342 is slidably arranged on the sliding seat 230, the lower end of the vertical bar 2342 is sleeved on the valve core 232, and the protrusion 2121 inserted into the transfer disk 211 can abut against the abutment portion 2341a, so that the sliding member 234 moves. This structure makes the structure of the sliding member 234 more reasonable and the movement smoother.

[0059] It can be understood that the structure of the second glue applying component 43 is the same as that of the first glue applying component 23, and the plugging transfer disk 211 of the middle plug transfer component 41 is also provided with a protrusion 2121, and its structure is the same as the structural principle of the plugging transfer disk 211 of the bottom plug transfer component 21, which will not be repeated here.

[0060] Refer to Figure 1 and Figure 2 The first push component 24 is arranged below the plug-in transfer disk 211 of the bottom plug transfer component 21, and is used to push the bottom plug 20 from the bottom of the paper tube 10 into the paper tube 10. The first push component 24 includes a cam 241, a compression spring 242, a push rod 243 and a guide plate 244. The push rod 243 is provided with a plurality of mounting grooves corresponding to each other. The guide plate 244 is provided with a plurality of through holes. The plurality of push rods 243 are respectively penetrated through the plurality of through holes. The lower end of the push rod 243 is provided with a follower 2431. The compression spring 242 is sleeved on the outer circumference of the push rod 243 and the two ends are respectively against the guide plate 244 and the follower 2431. When the guide plate 244 rotates, the push rod 243 can be driven to rotate. The follower 2431 is against the curved surface of the cam 241 to realize the lifting and lowering movement of the push rod 243, so that the bottom plug 20 can be pushed into the paper tube 10.

[0061] In order to prevent the paper tube 10 from not moving when the first pushing component 24 pushes the bottom plug 20 into the paper tube 10, the bottom plug transfer component 21 also includes a limit plate 212 and an outer guard plate 213. The limit plate 212 of the bottom plug transfer component 21 is arranged at the upper end of the insertion transfer disk 211 of the bottom plug transfer component 21. When the paper tube 10 is located in the installation groove, the upper end of the paper tube 10 can abut against the limit plate 212 of the bottom plug transfer component 21. The outer guard plate 213 is arranged around the outer peripheral surface of the insertion transfer disk 211, and the inner surface of the outer guard plate 213 can abut against the outer peripheral surface of the paper tube 10. This structure enables the push rod 243 of the first pushing component 24 to push the bottom plug 20 into the paper tube 10, and the side and top of the paper tube 10 are limited, so that the position of the paper tube 10 is fixed, and the bottom plug 20 is pushed in more smoothly.

[0062] The second pushing component 44 is disposed above the plug-in transfer disk 211 of the middle plug transfer component 41, and is used to push the middle plug 30 into the paper tube 10 from above the paper tube 10. The second pushing component 44 has the same structure as the first pushing component 24, which will not be repeated here. The middle plug transfer component 41 also includes a limit plate 212 and an outer protective plate 213. The limit plate 212 of the middle plug transfer component 41 is disposed at the lower end of the plug-in transfer disk 211 of the middle plug transfer component 41, so that the lower end of the paper tube 10 abuts against the limit plate 212 of the middle plug transfer component 41. The outer protective plate 213 is surrounded by the outer peripheral surface of the plug-in transfer disk 211, and the inner surface of the outer protective plate 213 can abut against the outer peripheral surface of the paper tube 10.

[0063] In this embodiment, a plurality of protrusions 2121 are evenly arranged on the outer circumference of the limiting plate 212 , and when the transfer disk 211 is inserted, it can drive the limiting plate 212 to rotate simultaneously.

The drying fixing seat 252 of the first drying component 25 is arranged around the outer peripheral surface of the drying transfer disk 251 and is located below the drying transfer disk 251 of the first drying component 25. A microwave cavity 2521 is arranged at one end facing the drying transfer disk 251. The microwave cavity 2521 is aligned with the part of the paper tube 10 where the bottom plug 20 is arranged. The height of the microwave cavity 2521 is not lower than the height of the bottom plug 20, so that the microwave cavity 2521 can cover the entire bottom plug 20, and the microwave cavity 2521 can cover multiple bottom plugs 20 at the same time. When the microwave generator 253 emits microwaves into the microwave cavity 2521, multiple bottom plugs 20 can be heated and dried at the same time to improve efficiency.

[0065] The drying fixed seat 252 of the second drying component 45 is arranged around the outer peripheral surface of the drying transfer plate 251 and is located in the middle of the drying transfer plate 251 of the second drying component 45, so that the microwave cavity 2521 of the second drying component 45 can be aligned with the part of the paper tube 10 where the middle plug 30 is set to dry the middle plug 30.

[0066] In order to further improve the drying efficiency, Figure 5 As shown, first bosses 2511 are provided on both sides of any mounting groove on the drying transfer plate 251 of the first drying component 25. When the paper tube 10 is arranged in the mounting groove, the outer surface of the first boss 2511 is higher than the paper tube 10, and the portion of the paper tube 10 where the bottom plug 20 is arranged is located between the first bosses 2511 on both sides of the mounting groove to form a relatively sealed space, so as to make the drying efficiency of the bottom plug 20 higher. The first boss 2511 extends upward from the bottom end of the drying transfer plate 251 of the first drying component 25 to the position where the bottom plug 20 is arranged on the paper tube 10 and is higher than the bottom plug 20.

[0067] like Figure 6 As shown, the second bosses 2512 are arranged on both sides of any installation groove on the drying transfer plate 251 of the second drying component 45. When the paper tube 10 is arranged in the installation groove, the outer surface of the second boss 2512 is higher than the paper tube 10, and the part of the paper tube 10 where the middle plug 30 is arranged is located between the second bosses 2512 on both sides of the installation groove to form a relatively sealed space, so as to make the drying efficiency of the middle plug 30 higher. The second boss 2512 extends upward from the bottom end of the drying transfer plate 251 of the second drying component 45 to the position where the middle plug 30 is arranged on the paper tube 10 and is higher than the middle plug 30.

[0068] The bottom end of the drying fixed seat 252 of the first drying component 25 extends toward the drying transfer plate 251 , and the extended portion of the drying fixed seat 252 of the first drying component 25 fits with the bottom surface of the drying transfer plate 251 to reduce microwave loss and improve the drying efficiency of the bottom plug 20 .

[0069] The feeding assembly 3 also includes a silo 31 and a rotating disk 33. The rotating disk 33 has a accommodating cavity. The bottom of the accommodating cavity is provided with a plurality of unloading holes 331 corresponding to the mounting grooves of the feeding transfer disk 32. The rotating disk 33 is provided with a scraper 332. The scraper 332 divides the accommodating cavity into a temporary storage area and an unloading area. The lower end of the rotating disk 33 is provided with a baffle plate 333 at the part of the temporary storage area. The silo 31 transports the material to the temporary storage area. The material can be filled in the unloading hole 331 and supported on the baffle plate 333. When the rotating disk 33 and the feeding transfer disk 32 rotate synchronously, the unloading hole 331 filled with the material enters the unloading area through the scraper 332, and the material falls and is filled in the paper tube 10 provided on the mounting groove. This structure enables the granular material to be filled in the paper tube 10.

[0070] Furthermore, the feeding hole 331 is set in an inverted cone shape, and the cross-sectional size of the feeding hole 331 gradually increases from the silo 31 to the feeding transfer plate 32. The inverted cone-shaped feeding hole 331 in this structure is more conducive to the flow of materials and improves the accuracy of filling.
