[0002] Slim cigarette packs are placed in boxes and need to be removed for order allocation. Conventionally, this is done manually, with the packs being fed into an order allocation device. This method is inefficient and labor-intensive. To address this issue, the inventor designed a slim cigarette pack opening machine (publication number CN117533618A). However, the top ear opening device can only perform suction cutting for boxes of fixed heights. The top ear suction cup cannot be adjusted in height, making it unsuitable for cutting top ear boxes of various heights on the production line. This results in low equipment utilization and high equipment costs. Summary of the Invention

Detailed Implementation

[0008] The present invention will be further described below with reference to specific embodiments.

[0009] Example 1: Refer to Figure 1-5 As shown, the upper ear opening device of the case opening machine includes an upper ear centering and cutting assembly 201, a pressure plate 202, and a second-station conveyor 203. The upper ear centering and cutting assembly 201 is installed on the upper ear centering frame 228 and is used to press the lower ear plates 8 on both sides of the case 6 and cut the tape on both sides of the upper ear plate 7. Two vertical connecting arms 239 are provided at the left and right ends of the upper ear centering frame 228. The two vertical connecting arms 239 are connected to the upper ear frame assembly 204 through the upper ear lifting linkage drive mechanism. The pressure plate 202 is connected to the upper ear lifting linkage drive mechanism and moves in conjunction with the upper ear centering frame 228 to form a linkage mechanism. The box body is centered and locked by cutting. The pressure plate 202 is vertically slidably connected to the top of the upper ear frame assembly 204. The second-station conveyor 203 is installed in the middle of the bottom side of the upper ear frame assembly 204. The upper ear centering and cutting assembly 201 centers the box body and cuts the tape at both ends of the upper ear plate on both sides. The pressure plate cylinder presses down on the box body to prevent shaking or movement. The second-station conveyor 203 transports the box body. The second-station conveyor includes multiple rollers, a conveyor frame, and a conveyor motor. The multiple rollers are evenly spaced and connected to the top of the conveyor frame. Adjacent rollers are connected by a multi-wedge belt for transmission. A roller is connected to the motor shaft of a conveyor motor via a multi-wedge belt. The conveyor motor is installed inside the conveyor frame. Driven by the conveyor motor, all rollers rotate in one direction. The system also includes a second stop assembly 212, which is mounted on a second-station conveyor 203 and extends out from the roller gap of the second-station conveyor 203 for limiting. When the box is conveyed by the second-station conveyor, it reaches the second stop assembly 212 and is stopped. The upper ear lifting linkage drive mechanism drives the pressure plate 202 to descend and the upper ear centering and cutting assembly 201 to descend in a coordinated manner to achieve centering pressure. Hold the housing 6, control the upper ear centering cutting component to align and fix the upper ear plate and cut the tape at both ends. After cutting, control the linkage pressure plate 202 to rise and drive the upper ear centering cutting component 201 to rise and release the aligned housing 6, and retract the limit of the second parking component 212. Under the power of the second station conveyor 212, it enters the next station (the lower ear opening device opens the lower ear). The upper ear lifting linkage drive mechanism is used to link the upper ear centering cutting component and the pressure plate 1 (same as above and below) to realize the centering of the housing, thereby facilitating the centering and adsorption fixation of the upper ear, and adapting to the needs of different housing height changes.

[0010] The second parking device assembly 212 includes an L-shaped baffle and a limiting telescopic cylinder. The baffle is fixedly connected to the upper ends of two stop-start guide rods. The two stop-start guide rods are connected to a crossbeam via stop-start linear bearings. The crossbeam is fixedly connected to the conveyor frame. The cylinder rod of the limiting telescopic cylinder is fixedly connected to the middle of the baffle. The two stop-start guide rods are arranged on both sides. The cylinder seat of the limiting telescopic cylinder is fixedly connected to the crossbeam. By the action of the limiting telescopic cylinder, the baffle is controlled to extend out of the roller 134 or retract, thereby realizing the parking and opening of the box. The baffle has an L-shaped cross section and good rigidity.

[0011] Specifically, the upper ear lifting linkage drive mechanism includes an upper ear vertical slider guide rail pair 240, a frame lifting drive arm 241, a drive shaft 242, a pressure plate lifting drive arm 243, a pressure plate lifting guide rod 244, and an upper ear lifting power mechanism 245. The two ends of the drive shaft 242 are rotatably connected to the inner top of the upper ear frame assembly 204 via bearing seats. Two vertical connecting arms 239 are connected to both sides of the upper ear frame assembly 204 via two upper ear vertical slider guide rail pairs 240. Two symmetrically arranged frame horizontal slide grooves 246 are fixedly connected to the upper ends of the two vertical connecting arms 239. The grooves of the two frame horizontal slide grooves 246 are arranged horizontally relative to each other. Two frame lifting drive arms 243 are used, with one end symmetrically fixed via a sleeve connection (using screw locking). A frame drive roller 233 is rotatably connected to a drive shaft 242 at one end and a frame drive roller 233 at the other end. The frame drive roller 233 is placed in a frame horizontal slide groove 246 and can move within the frame horizontal slide groove 246. The frame lifting drive arm 241, which rotates around the drive shaft 242, can drive the two vertical connecting arms 243 to move up and down along the upper ear vertical slider guide rail pair 240. One end of the pressure plate lifting drive arm 243 is fixedly connected to the middle of the drive shaft 242 and is parallel to the frame lifting drive arm 241 on the same side of the drive shaft 242. The length of the frame lifting drive arm 241 is half the length of the pressure plate lifting drive arm 243. That is, when the box is pressed together: when the pressure plate 202 descends a distance of 2H, the upper ear is aligned with the middle frame. The frame 228 descends a distance H to open the housing. When the housing is released, the pressure plate 202 and the upper ear centering frame 228 rise and move in opposite directions. The other end of the pressure plate lifting drive arm 243 is rotatably connected to a pressure plate drive roller 247. The top surface of the pressure plate 202 has a horizontal sliding groove 234, which consists of two symmetrical strip-shaped through holes located on the two side walls along the length of the upper-opening strip-shaped groove. The pressure plate drive roller 247 is symmetrically positioned within the two strip-shaped through holes of the horizontal sliding groove 234. Two pressure plate lifting guide rods 243 are symmetrically fixed to the front, rear, and center of the top surface of the pressure plate 202. These guide rods are connected via a pressure plate lifting linear bearing 235. At the top of the upper ear frame assembly 204, the pressure plate lifting drive arm 243, which rotates around the drive shaft 242, can drive the pressure plate 202 to move up and down along the pressure plate lifting guide rod 244. The drive shaft 242 is connected to the upper ear lifting power mechanism 245 that drives its rotation. The upper ear lifting power mechanism 245 is mounted on the top of the upper ear frame assembly 204 and includes an upper ear drive motor 236 and a double-row sprocket transmission mechanism 237. The upper ear drive motor 236 is fixedly connected to the top of the upper ear frame assembly 204. The driving double-row sprocket of the double-row sprocket transmission mechanism 237 is fixedly connected to the motor shaft of the upper ear drive motor 236, and the driven double-row sprocket of the double-row sprocket transmission mechanism 237 is fixedly connected to the drive shaft 242.It adopts a double-row chain drive, providing ample power to ensure the power requirements and transmission stability for lifting and pressing.

[0012] The working principle of the upper ear lifting linkage drive mechanism is as follows: When it is necessary to press the box 1, the box stops on the supporting conveyor (the second station conveyor 203, and the lower ear lifting linkage drive mechanism is the third station conveyor). The upper ear lifting power mechanism drives the rotating shaft to rotate, and the pressure plate lifting drive arm 243 drives the pressure plate 202 to descend along the pressure plate lifting guide rod 244 until it is pressed against the top surface of the box. At the same time, the frame lifting drive arm 241 synchronously drives the upper ear centering frame 228 to descend, so that the upper ear centering cutting component 201 descends synchronously, and finally ensures that the suction cup adsorbs the ear plate of the box (the pressure plate descends 2H, and the upper ear centering cutting component 201 descends H). After the box is finally pressed, the adsorption and cutting of the ear plate are completed by the upper ear centering cutting component 201. When it is necessary to release the box, the rotating shaft is rotated in the opposite direction.

The arc-shaped surface of the slicing blade 205 faces upward. Two sets of arc-shaped slicing blades 205 are used, with two blades in each set arranged opposite each other and able to move relative to each other under the drive of the longitudinal and transverse lifting and moving mechanism 206 to simultaneously cut the tape on both sides. Each set of slicing blades 205 is connected to the left and right sides of the upper ear centering frame 228 through the longitudinal and transverse lifting and moving mechanism 206. The telescopic suction cup assembly 207 is installed on the longitudinal and transverse lifting and moving mechanism 206 to adsorb the upper ear.

The two ends of the longitudinal guide rod 219 are fixedly connected to two brackets 220. 220 is fixedly connected to the base frame 221. A scriber lifting cylinder 213 controls the sliding mounting plate 215 to move vertically along the lifting guide rail pair 214, realizing the vertical movement of the scriber. Two scribers can move relative to each other on the longitudinal guide rod 219 via a linear bearing seat 218. The longitudinal movement assembly 210 includes a horizontal longitudinal sliding plate 216, a longitudinal guide rail pair 222, and a longitudinal telescopic cylinder 223. One end of the horizontal longitudinal sliding plate 216 is fixedly connected to a slider of the longitudinal guide rail pair 222, and the rear end extends backward and is vertically bent to form a bent part.

Driven by the longitudinal telescopic cylinder 223, the linear bearing seat 218 moves along the longitudinal guide rod 219. The lateral movement assembly 211 includes the base frame 221, the rotating seat 226, and the lateral guide rail pair 227. The bottom frame 221 is fixedly connected at both ends to the sliders of two transverse guide rail pairs 227.
