[0076] The entrance rubber tapping device 100 of this embodiment is provided for cutting the packing tape at the bonding point of the upper and lower flaps of the carton entering the workstation 1 of the right frame component 720. The device is installed at the entrance of the right frame component 720 by connecting the two ends of the first substrate 110 to the right frame component 720. At this time, the conveying component of the right frame component 720 for conveying the carton is arranged in the channel formed by the first vertical plate 121 and the second vertical plate 122 carton on the first opening and closing component 120, providing conveying and guiding functions for the carton to enter the right frame component 720. The passage is opened by moving the first vertical plate 121 and the second vertical plate 122 on the first opening and closing component 120 away from each other. At this time, the entrance rubber tapping device 100 is in a pre-carton receiving state. When the carton enters the passage, the first vertical plate 121 and the second vertical plate 122 approach each other to adapt the passage to the size of the carton. At this time, the first transmission component 141 and the second transmission component 142 respectively arranged on the first vertical plate 121 and the second vertical plate 122 clamp and convey the opposite sides of the carton to make the carton pass through the passage. At the same time, the carton moves relative to the first knife holder 131 and the second knife holder 132 installed on the first vertical plate 121 and the second vertical plate 122, providing a cutting function for the packing tape at the bonding point of the upper and lower flaps of the carton. By arranging a swing spring 1314 between the tension spring seat 1313 and the swing rod 1315, the swing spring 1314 provides an elastic force for the swing rod 1315 to rotate in the direction of the channel, so that the inlet knife disc assembly 1316 installed at the end of the swing rod 1315 is close to the channel. When the carton passes through the channel, the inlet knife disc assembly 1316 is pressed against the side of the carton under the action of the elastic force. When facing some cigarette cartons of the same specification but different batches, or when there is a certain size error caused by the transmission gap, the inlet knife disc assembly 1316 can always be pressed against the side of the carton through the automatic adjustment effect of the swing spring 1314; at the same time, by arranging a knife disc depth limit plate on the side of the knife disc, the knife disc depth limit plate has a depth limit surface. When the knife disc cuts the tape packing tape between the upper and lower flaps of the carton, the depth limit surface abuts against the surface of the carton, thereby limiting the further penetration of the knife disc and reducing the risk of scratching the strip box inside the carton. The cutting depth is controlled by the distance between the depth limit surface and the edge of the knife disc. It realizes the rubber tapping of cartons of different sizes within a certain range, greatly improving the compatibility, practicality and stability of the equipment.

The lifting screw is arranged in parallel with the lifting rail. The upper end of the lifting screw extends from the top of the tool holder top plate through the through hole. A hand wheel is fixed to the end of the lifting screw above the tool holder top plate. A spacer is arranged between the hand wheel and the tool holder top plate. The spacer is arranged around the lifting screw and provides support for the trapezoidal bolt through the spacer. A flange nut is provided on the lifting screw threaded connection below the tool holder top plate. The outer side of the flange nut is fixed to the lifting mounting plate 1312. The lifting screw is rotated by turning the hand wheel, so that the flange nut moves in the axial direction of the lifting screw, so as to adjust the position of the cutter disc on the lifting mounting plate 1312 in the vertical direction. After the adjustment is completed, the locking handle is used to squeeze the locking groove, and the diameter of the through hole is reduced by holding the shaft, so that the lifting screw is locked in the through hole, limiting the further rotation of the lifting screw and locking the position of the cutter disc.

[0080] In this embodiment, torque is manually input to the lifting screw through a hand wheel, which is low-cost and easy to adjust. In some other implementations, torque can also be input through a servo motor to improve the degree of automation of the equipment, and the position of the cutter disc can be adjusted. Technical personnel in this field can implement it according to actual conditions.

[0081] A swing guard plate is arranged outside the lifting installation plate 1312 and the lifting screw rod, and the swing guard plate has a limit surface that can limit the excessive displacement of the swing rod 1315. The swing guard plate of this embodiment plays a protective role, and at the same time, the swing guard plate can limit the swing rod 1315 from rotating in a direction away from the channel, preventing the swing tension spring 1314 from breaking and causing the swing rod 1315 to reverse and pop out accidentally, thereby further improving the safety of the equipment.

Define the direction in which the first synchronous pulley points to the second synchronous pulley as the first direction, and the direction in which the second synchronous pulley points to the first synchronous pulley as the first direction, then the synchronous toothed belts on both sides of the first synchronous pulley and the second synchronous pulley form a first direction segment and a second direction segment respectively, the first direction segment is the synchronous toothed belt in the direction in which the first synchronous pulley points to the second synchronous pulley, and the second direction segment is the synchronous toothed belt in the direction in which the second synchronous pulley points to the first synchronous pulley;

[0151] The input clamp is fixed to the first direction section, and the input clamp is arranged near the first synchronous pulley; the bottom of the input clamp is connected to the horizontal plate of the fixed frame at the bottom of the fixed frame 410 near one end of the push plate assembly 440 through the clamp seat. The output clamp is fixed to the second direction section, and the output clamp is arranged near the second synchronous pulley, and the side of the output clamp is connected to the inner side of the secondary frame side plate; thereby, the relative displacement between the primary frame 421 and the fixed frame 410 provides power, driving the secondary frame 431 to move back and forth along the length direction of the primary frame 421.

[0153] When in use, the servo motor provides power, and the lead screw is driven to rotate through the driving wheel, the power wheel and the transmission belt, and the rotation drives the lead screw to rotate forward and backward, thereby driving the primary frame 421 to translate back and forth relative to the fixed frame 410, thereby realizing the telescopic function of the primary pushing assembly 420. When the primary pushing assembly 420 is extended relative to the fixed frame 410, the synchronous pulley set fixed on the primary frame 421 and the input splint fixed on the fixed frame 410 produce relative movement, so that the input splint moves in the first direction (i.e., the direction in which the first synchronous pulley points to the second synchronous pulley), and the first synchronous pulley and the second synchronous pulley rotate under the drive of the synchronous toothed belt, driving the output splint to move in the second direction (i.e., the direction in which the second synchronous pulley points to the first synchronous pulley), driving the secondary frame side plate fixed to the output splint to move, and driving the secondary frame 431 to move relative to the primary frame 421 in the second direction, i.e., the secondary frame 431 extends from the primary frame 421, thereby realizing the telescopic function of the secondary pushing assembly 430.
