The screws 107 are provided with pulleys 108, and a transmission belt is connected between the pulleys 108.

[0035] The clamping assembly 300 has two clamping assemblies 300, and the clamping assembly 300 includes a support frame 301, a servo electric cylinder 303, a clamping plate 304, a movable groove 305, a rubber balloon 306 and a movable plate 307. The servo electric cylinder 303 is arranged at the bottom of the support frame 301, and the movable rod of the servo electric cylinder 303 is connected to the clamping plate 304. A movable groove 305 is opened on one side of the bottom of the clamping plate 304, and the opening of the movable groove 305 is connected to the movable plate 307. The movable groove 305 contains hydraulic oil, and the inner cavity of the movable groove 305 contains several rubber balloons 306. The material of the movable plate 307 is rubber.

[0036] The clamping assembly 300 also includes a connecting skin 1 309, a bent plate 311 and a connecting skin 2 312. The top of the movable plate 307 is provided with a bent plate 311, and the bent plate 311 is an arc-shaped elastic connecting plate. The top of the bent plate 311 is provided with a connecting skin 2 312. The top of the connecting skin 2 312 is connected to the inner side of the inner top wall of the movable groove 305. The top of the connecting skin 2 312 is more than 5 mm away from the opening edge of the movable groove 305. The connecting skin 1 309 is connected between the bottom end of the movable plate 307 and the inner bottom wall of the movable groove 305. The two clamping plates 304 are a group and are arranged face to face. The material of the bent plate 311 is hard plastic, and the materials of the connecting skin 2 312 and the connecting skin 1 309 are rubber.

[0037] The bent plate 311 has a smooth transition effect.

[0038] The second connecting skin 312 is located on the inner side of the movable groove 305, so that when the paper is inserted between the two clamping plates 304, the bottom end of the paper will directly collide with the outer side of the second connecting skin 312, and the bottom end of the paper will reach the outer side of the movable plate 307 along the second connecting skin 312 and the bent plate 311.

[0039] The clamping assembly 300 further includes a connecting rope 310, and the connecting rope 310 is arranged between the rubber balloons 306, and a connecting rope 312 is also connected between part of the rubber balloons 306 and the inner wall of the movable groove 305;

[0040] The rubber balloon 306 allows the liquid inside the movable tank 305 to shrink in volume.

[0041] The clamping assembly 300 further includes a second guide rod 302 and a retaining ring 308. The second guide rod 302 is disposed on one side of the top of the clamping plate 304. The second guide rod 302 is movably plugged with the support frame 301. The retaining ring 308 is disposed on one side of the support frame 301 facing the clamping plate 304.

[0042] The material of the retaining ring 308 is elastic rubber, and the second guide rod 302 makes the support frame 301 more stable during linear motion.

[0043] The binding machine assembly 100 further includes a guide rod 106. Two groups of horizontal guide rods 106 are arranged inside the movable chamber 102. The guide rods 106 pass through the support frame 301. The support frame 301 is movably connected to the guide rods 106. Each group of guide rods 106 is composed of two guide rods 106.

[0044] The guide rod 106 makes the linear motion of the support frame 301 more stable.

[0045] The glue binding machine assembly 100 further includes a hot melt glue box 103 and a fan 104. A transport assembly 200 is disposed on one side of the inner bottom wall of the active cavity 102, a fan 104 is disposed on the other side of the inner bottom wall of the active cavity 102, and a hot melt glue box 103 is disposed in the middle of the inner bottom wall of the active cavity 102;

[0046] The hot melt glue box 103 applies glue to the paper, and the fan 104 blows out air to dry the paper.

[0047] The transport assembly 200 includes a box 201, a running chamber 202, a sliding roller 203 and a transport belt 204. The box 201 has a running chamber 202 at the top. Two sliding rollers 203 are rotatably connected to the inside of the running chamber 202. The outside of the sliding roller 203 is wrapped with a transport belt 204. The transport belt 204 is in contact with the bottom end of the support frame 301.

[0048] The conveyor belt 204 supports the bottom of the paper and moves along with the support frame 301. When the sliding roller 203 rolls, the conveyor belt 204 moves and operates.

[0049] The specific implementation method is as follows: put the paper flat from the position between the two clamping plates 304, and the bottom of the paper touches the transport component 200 to stop. Then, the servo electric cylinder 303 pushes the two clamping plates 304 closer to each other, and the movable plates 307 on the clamping plates 304 respectively press against one side of the paper to clamp the paper. The motor 105 drives the two screw rods 107 to rotate synchronously. The screw rods 107 control the two clamping plates 304 and the clamped paper to pass through the hot melt glue box 103 and the fan 104 in turn. The hot melt glue box 103 applies glue liquid, and the fan 104 makes the glue liquid dry.

[0050] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
