[0034] The described dispensing mechanism includes a pusher 7, a fixing unit, and a glue discharging unit. The pusher 7 is a common pneumatic cylinder body, which is connected to an external controller and a gas source. The structure and usage mode of the pneumatic cylinder body are well-known prior arts to those skilled in the art and will not be elaborated here. The pusher 7 is provided with a push rod, and an installation block 71 is fixedly arranged at the bottom of the push rod. An installation hole is arranged at the front part of the installation block 71, and the installation hole is a threaded hole.

[0035] The described fixing unit includes a fixing frame 72 and a connecting piece. The fixing frame 72 is used to fixedly clamp the glue discharging unit. A fixing groove and a clamping hole are arranged on the fixing frame 72. An installation through hole is also arranged at the front part of the fixing frame 72, and the installation through hole is arranged corresponding to the installation hole. The connecting piece is a screw. The installation frame is fixedly installed at the front part of the installation block 71 through the screw.

[0036] The described glue discharging unit includes a glue discharging pipe 73, and the top of the glue discharging pipe 73 is connected to a glue discharging mechanism. Specifically, the structure and usage mode of the glue discharging pipe 73 and the glue discharging mechanism are well-known prior arts to those skilled in the art and will not be elaborated here. The glue discharging pipe 73 is sleeved and fixed in the clamping hole.

[0037] The described dispensing mechanism further includes a pressing elastic sheet 74 and a pressing driver, and the pressing driver is fixed on the frame 1. The pressing elastic sheet 74 is pressed down under the drive of the pressing driver to limit the position of the binding tape when the binding tape and the stack of papers are at the dispensing position. A friction block 75 is fixedly arranged at the front section of the pressing elastic sheet 74 to assist in giving a certain frictional force to the binding tape so that the binding tape fits tightly with the front part of the stack of papers.

[0038] The described dispensing mechanism further includes a pressing head 8, and the pressing head 8 is rotatably arranged at the lower part of the support plate 11. An opening matching the pressing head 8 is arranged on the support plate 11 so that the pressing head 8 rotates and is exposed. The lower end of the pressing head 8 is connected to a pressing rotating shaft, and the pressing rotating shaft is driven to rotate by a motor. An elastic stop block 81 is arranged above the dispensing mechanism, and the elastic stop block 81 cooperates with the pressing head 8 to bend and deform the binding tape, facilitating the formation of the dispensing.

[0039] A collecting mechanism is further included. The collecting mechanism includes a collecting push rod 9 and a collecting stop bar 91. The collecting push rod 9 pushes the bundled stack of papers to the rear part of the frame 1 under the drive of a driver. The collecting stop bar 91 is installed and fixed through baffles 21 arranged on both sides of the frame 1 to block the stack of papers pushed by the collecting push rod 9, facilitating subsequent processes such as packing and storage.

[0040] Usage process: Start the device. The separation driver 23 drives the snap fastener to slide on the partition piece 24 after the adjustment and installation. When the snap fastener moves downward, it pushes the lower end of the partition piece 24 to move outward, that is, away from both sides of the material in the storage bin 2. Subsequently, when the snap fastener rises under the drive of the separation driver 23, the lower end of the partition piece 24 moves toward the storage bin 2. The lower end of the partition piece 24 passes through the partition opening 22 and lifts the paper above the height of the pre-treated paper stack inside the storage bin 2 upward. The electric push rod drives the separation plate 16 to move and insert into the gap between the formed papers. The feeding push plate 15 pushes the remaining stacked papers below the separated position of the separation plate 16 to move in a stack. If there is excess paper at the top of the stacked papers, the height baffle 25 blocks the excess paper at the top of the stacked papers. The bottom pre-treated paper stack is pushed below the discharge belt 31. The discharge belt 31 drives the paper stack to move and longitudinally tightens the paper stack with the auxiliary piece 33, and tightens the paper stack to drive it below the limit piece 4.

[0041] The movement of the material conveyor belt 5 causes the pushing protrusion 51 to abut against the edge of the paper stack and continuously drives the paper stack to move.

[0042] When the paper stack is pushed by the pushing protrusion 51 to below the tape winding unit, the paper stack position is sensed by the photoelectric sensor, and the tie strap transportation unit is started. The lowermost tie strap in the tie strap stack rotates downward by friction to reach the position of the guiding piece 62, and the lower part of the tie strap is inserted into the preset opening of the support plate 11. The paper stack is pushed to bend at the pressure belt piece 63, so that one side of the advancing direction of the paper stack abuts against one side of the tie strap. Driven by the material conveyor belt 5, the pressure belt piece 63 and the support plate 11 respectively bend the upper and lower sections of the tie strap, so that the tie strap fits the upper and lower surfaces of the advancing paper stack.

[0043] When the tie strap and the paper stack run to below the dispensing mechanism, the pressing driver drives the pressing elastic piece 74 to press the tie strap to make it further shaped. The dispensing head dispenses glue on the tie strap under the drive of the pushing protrusion. After the dispensing is completed, the dispensing mechanism returns to the initial state, and the pressing head 8 rotates to press the tail of the tie strap against the glue application part, realizing the adhesion and closing of the tie strap to the paper stack. The completed paper stack breaks away from the position of the support plate 11 with the inertia of the push of the material conveyor belt 5 and reaches in front of the collecting push rod 9. The collecting push rod 9 senses the arrival of the material through the photoelectric sensor and pushes the paper stack to the collecting stop bar 91 for subsequent processing.

[0044] Example 2, asFigures 7 to 9 As shown, on the basis of Embodiment 1, a cover adding mechanism is further provided between the paper feeding mechanism and the bundling mechanism. The cover adding mechanism includes a fixing plate 3, a discharging belt 31, a driving belt pulley 32, a limiting block, and an auxiliary piece 33. The fixing plate 3 is obliquely fixed at the next working step position of the paper feeding mechanism of the frame 1. A pulley of the discharging belt 31 is arranged below the fixing plate 3. The driving belt pulley 32 is arranged on a driving belt pulley rotating shaft, the driving belt pulley rotating shaft is rotatably arranged in a bearing, and the outer ring of the bearing is fixedly arranged on the frame 1 through a bearing base. The driving belt pulley rotating shaft is driven by a motor arranged on one side of the frame 1. The limiting block is fixedly arranged above the front part of the discharging belt 31. A number of cover papers for standby use are stored on the fixing plate 3. A gap between the limiting block and the discharging belt 31 allows one cover paper to pass through.

[0045] The auxiliary piece 33 is in a curved shape with a protruding tail. The auxiliary piece 33 is arranged between two groups of the material conveyor belts 5. The paper stack pushed out by the paper feeding mechanism is pushed by the material conveyor belts 5 and gradually rises along the auxiliary piece 33, so that the paper stack finally runs to the upper part of the cover paper and merges with the cover paper to form a new paper stack with a cover at the bottom to be bundled, so as to increase the aesthetic degree.
