The driving wheel and the driven wheel are connected by an annular transmission chain 209, and the driving wheel is driven by a motor on one side thereof.

[0033] The fixing plates 200 on both sides of the lifting frame 2 are respectively fixedly mounted with guide rails 204 that cooperate with the sliding block 105 for guidance.

[0034] The screw rod assembly includes a screw rod 215, which is horizontally installed between the right end of the fixing frame 2 and the mounting plate 202 at the right end.

[0035] The base plate 301 is provided with fixed seats 308 arranged at intervals, and the long axis 307 is mounted on the base plate 301 through the fixed seats 308. The long axis 307 is provided with transverse bevel gears 306 arranged at intervals, and one side of the transverse bevel gear 306 is respectively installed with a longitudinal bevel gear 305 meshing with it at an angle of 90 degrees.

[0037] When the above structures are working, they are distributed in pairs on both sides of the circulating conveyor belt, and are staggered and arranged relative to each other. The guide rod of the cylinder 313 on the box supporting mechanism 3 extends, and the transmission plate 312 drives the long shaft 307 to rotate, and the long shaft 307 drives the transverse bevel gear 306 and the left and right box supporting plates 309 to rotate counterclockwise. Further, the transverse bevel gear 306 drives the longitudinal bevel gear 305 to rotate, and the longitudinal bevel gear 305 drives the front and rear box supporting baffles 310 to flip, so that the left and right box supporting plates 309 and the front and rear box supporting baffles 310 remain in a horizontal state.

[0038] Further, if Figure 5 As shown, when the carton enters the packing position with the conveyor, the guide rod of the cylinder 313 installed on the cylinder seat 311 of the bottom plate 301 shrinks, and the transmission plate 312 rotates downward, driving the long shaft 307 to rotate clockwise. The rotation of the long shaft 307 drives the transverse bevel gear 306 and the left and right box support plates 309 to rotate clockwise. At the same time, the transverse bevel gear 306 drives the longitudinal bevel gear 305 to rotate. Further, the clockwise rotation of the long shaft 307 rotates the left and right box support plates 309 downward, and the rotation of the longitudinal bevel gear 305 also rotates the front and rear box support plates 310 downward, supporting the four cover plates of the carton outward, and at this time, the secondary packing machine packs the carton. When the packing is completed, the guide rod of the cylinder 313 on the box support mechanism 3 extends, and the transmission plate 312 drives the long shaft 307 to rotate, and the long shaft 307 drives the transverse bevel gear 306 and the left and right box support plates 309 to rotate counterclockwise. Further, the transverse bevel gear 306 drives the longitudinal bevel gear 305 to rotate, and the longitudinal bevel gear 305 drives the front and rear box support baffles 310 to flip, so that the left and right box support plates 309 and the front and rear box support plates 310 remain horizontal. At this time, the conveyor rotates to transport the boxed finished product to the next station.

[0039] Depend on Figures 1 to 4 As described above, the bottom frame 1 is composed of a front panel 100, a rear panel 101, an upper fixing plate 102, two reinforcing plates 103 and two side plates 104. A slider 105 connected to the lifting frame 2 is installed on the front panel. Figure 5 The conveyor shown is connected.

[0040] Furthermore, the lifting frame 2 is composed of a fixing plate 200, an upper fixing plate 201, a mounting plate 1 202, and a fixing frame 203. A driving screw 205 and a driven screw 211 are installed on the fixing frame 203, and the two screws are fixed to the fixing frame 203 through a rotating sleeve 217 and a bushing 218. The middle position of the two screws is connected to the upper fixing plate 102 on the bottom frame 1 through a nut 206. Guide rails 204 are installed on both sides of the lifting frame 2, and the guide rails 204 are connected to the slider 105 on the bottom frame 1 to maintain the balance of the lifting frame 2 when it is lifted.

[0041] Furthermore, a driving wheel 207 and a driving wheel 208 are installed on the upper end of the active screw rod 205 of the lifting frame 2, and a driven wheel 210 is installed on the driven screw rod 211. The active wheel 208 and the driven wheel 210 are connected by a ring transmission chain 209. When the driving wheel 207 rotates, the active wheel 208, the transmission chain 209, the driven wheel 210 and the active screw rod 205 are driven to rotate, and at the same time, the driven wheel 210 drives the driven screw rod 211 to rotate in the same direction. Since the middle position of the active screw rod 205 and the driven screw rod 211 is fixed to the bottom frame 1 by a nut 206, when the active screw rod 205 and the driven screw rod 211 rotate, the active screw rod 205 and the driven screw rod 211 will move up and down with the spiral, driving the lifting frame 2 and the box support mechanism 3 installed on the lifting frame 2 to move up and down accordingly.

[0042] Further, if Figure 1 As described, a motor 212 is installed on the mounting plate 1 202 at the right end of the lifting frame 2, and a driving wheel 213 is installed on the output shaft end of the motor 212. A screw rod 215 is installed on the upper part of the mounting plate 1 202, and a driven wheel 214 is installed on the right end of the screw rod 215. The driving wheel 213 and the driven wheel 214 are connected by a transmission belt 219. Two guide rails 216 are installed on the fixed plate 201 on the lifting frame 2. The guide rails 216 are connected to the slider 2 314 on the box supporting mechanism 3.

[0043] Further, if Figure 1 The box supporting mechanism 3 is composed of a nut plate 300, a bottom plate 301, a side plate 302, a vertical plate 303, a second mounting plate 304 and a cylinder seat 311. The nut plate 300 is connected to the screw rod 215 on the lifting frame 2. When the motor 212 rotates, it drives the second driving wheel 213, the transmission belt 219 and the second driven wheel 214 to rotate, and the second driven wheel 214 drives the screw rod 215 to rotate, and the rotation of the screw rod 215 drives the nut plate 300 to move left and right. The nut plate 300 drives the box supporting mechanism 3 to move left and right.

[0044] Further, if Figure 1 , Figure 2 , Figure 3As described above, the longitudinal bevel gear 305 is installed on the fixing seat 308 on the bottom plate 301 of the box supporting mechanism 3. The transverse bevel gear 306 is installed on the second mounting plate 304. The longitudinal bevel gear 305 is fixed to the long shaft 307. The longitudinal bevel gear 305 and the transverse bevel gear 306 form a 90-degree angle transmission connection.

[0045] like Figure 5 As shown, as the length of the carton is different, the box supporting mechanism 3 moves toward or away from each other under the drive of the motor 212. As the height of the carton is different, the box supporting mechanism 3 moves up and down under the drive of the active screw rod 205.
