[0033] Example 1:

[0034] like Figures 1 to 4 As shown, this embodiment provides a gluing mechanism, comprising: a gluing frame 21, a stopper 24, a first telescopic device 25, a glue tank 6, a cone head 66, and a transmission unit 7. The transmission unit 7 passes through the gluing frame 21, and the glue tank 6 is located on the side of the transmission unit 7. The first telescopic device 25 drives the glue tank 6 to move up and down relative to the gluing frame 21. The glue tank 6 has a glue cavity 60 formed therein. The glue tank 6 is fixedly connected to the cone head 66. The cone head 66 has a glue outlet 660 formed therein, and the glue outlet 660 is in communication with the glue cavity 60. The stopper 24 is located on the side opposite the glue tank 6. The transmission unit 7 can be a conveyor belt.

[0035] Based on the above technical solution, a second conical surface 661 is formed on the end of the cone head 66 away from the glue box 6 , and the glue outlet 660 is formed on the second conical surface 661 .

[0036] Based on the above technical solution, the glue box 6 includes a box cover 61 and a box body 62. The box cover 61 is fixed relative to the box body 62. The box cover 61 and the box body 62 are detachably connected. The box body 62 is formed with a connecting through hole 620. The two ends of the connecting through hole 620 are respectively connected to the glue chamber 60 and the glue outlet 660.

[0037] On the basis of the above technical solution, it also includes a threaded sleeve 64 and a blocking rod 65. The threaded sleeve 64 is fixedly connected to the box cover 61. The blocking rod 65 passes through the box cover 61 and the threaded sleeve 64. Part of the blocking rod 65 is formed with threads. The blocking rod 65 is threadedly connected to the threaded sleeve 64. The blocking rod 65 is located at one end of the glue chamber 60 and is formed with a first conical surface 651. The inner wall of the connecting through hole 620 is a conical surface. The first conical surface 651 is adapted to the conical surface of the connecting through hole 620. The blocking rod 65 coincides with the axis of the connecting through hole 620.

[0038] Based on the above technical solution, the end of the blocking rod 65 located outside the glue chamber 60 is formed with an enlarged portion 652 ; it also includes a sealing ring 67 , which is located between the box cover 61 and the blocking rod 65 .

[0039] On the basis of the above technical solution, it also includes a one-way valve 63, which is fixedly connected to the glue tank 6 and communicates with the glue chamber 60. The one-way valve 63 is connected to the pump through a hose with a sufficient length, and the pump is connected to the glue bucket;

[0040] It also includes a guide post 22 and a slider 23 . The guide post 22 is fixedly connected to the glue coating machine frame 21 , and the slider 23 is fixedly connected to the glue box 6 .

[0041] On the basis of the above technical solution, it also includes a first baffle 26 and a second telescopic device 27, the upper and lower ends of the second telescopic device 27 are fixedly connected to the glue coating frame 21 and the first baffle 26 respectively, and the first baffle 26 is located above the transmission unit 7;

[0042] The stopper 24 is a roller rotatably connected to the gluing machine frame 21 , a flat plate fixedly connected to the gluing machine frame 21 , or a conveyor belt.

[0043] Based on the above technical solution, the two glue boxes 6 are respectively located on the left and right sides of the transmission unit 7, and the cone heads 66 of the two glue boxes 6 are respectively located on the upper and lower sides of the upper surface of the transmission unit 7, and the tips of the cone heads 66 of the two glue boxes 6 are arranged opposite to each other.

[0044] Based on the above technical solution, the glue tank 6 is installed with a safety valve 68 and a pressure sensor 69. The safety valve 68 is used to discharge glue when the pressure is too high, and the pressure sensor 69 is used to detect the pressure of the glue to determine whether the operation is normal.

[0045] Working principle:

[0046] The corresponding connecting holes 620 are sealed based on the length and width of the cardboard bonding area. To seal, the sealing rod 65 is rotated, and the end of the rod 65 is inserted downward into the connecting hole 620. The cylindrical surfaces of the two rods mate, sealing the connecting hole 620. To release the seal, the sealing rod 65 is rotated upward and out of the connecting hole 620.

[0047] The cardboard 9 enters the gluing machine frame 21 along with the transmission unit 7, and the second telescopic device 27 drives the first baffle 26 to lower to block the cardboard 9 from moving along with the transmission unit 7 and position the cardboard 9 forward and backward. Preferably, the fourth telescopic devices 28 on both sides are used to position the cardboard 9 left and right.

[0048] Figure 1At least one of the first telescopic devices 25 on the left and right sides drives the corresponding glue tank 6 toward the cardboard 9. The cardboard 9 is stopped by the stopper 24, preventing it from being pushed by the cone 66. After the cone 66 is inserted into the cardboard 9, the glue in the glue chamber 60 is squeezed out of the glue outlet 660 under the drive of the pump and enters the blind hole in the cardboard 9. Preferably, the multiple cones 66 are arranged in a rectangular lattice.

[0049] After gluing is completed, the first telescopic device 25 drives the glue box 6 to move upward and reset, the second telescopic device 27 and the fourth telescopic device 28 are both reset, and the cardboard 9 moves to the next mechanism along with the transmission unit 7.

[0050] It should be noted that this mechanism can be used in a box gluer and a nail gluer. Figure 4 As shown, the blind holes on the upper and lower sides can be located on the same straight line or staggered. After curing, the glue 92 forms multiple protrusions in the blind holes of the cardboard 9. The protrusions are embedded in the blind holes. This not only embeds the protrusions at a macro level, but the newly formed blind holes also increase the bonding area, thereby enhancing the bonding strength between the two sides of the cardboard 9.

[0051] At the same time, the blind holes restrict the flow of glue inside them. The evenly arranged blind holes make the glue distribution more uniform, further increasing the bonding strength. The glue cannot flow freely, preventing the glue from overflowing the bonding area.

[0052] Example 2:

[0053] like Figures 1 to 6 As shown, this embodiment provides a high-speed fully automatic nail pasting machine using the gluing mechanism described in Example 1, including: a paper feeding mechanism 1, a folding mechanism 3 and a nail box mechanism 4, the paper feeding mechanism 1, the gluing mechanism 2, the folding mechanism 3 and the nail box mechanism 4 are arranged in sequence, and the transmission unit 7 passes through the paper feeding mechanism 1, the gluing mechanism 2, the folding mechanism 3 and the nail box mechanism 4.

[0054] On the basis of the above technical solution, it further includes an output mechanism 5, wherein the paper feeding mechanism 1, the gluing mechanism 2, the folding mechanism 3, the box stapling mechanism 4 and the output mechanism 5 are arranged in sequence;

[0055] It also includes a pressure wheel 8, a third telescopic device 41 and a second baffle 42. The pressure wheel 8 and the third telescopic device 41 are respectively located on both sides of the nail box mechanism 4. The third telescopic device 41 drives the second baffle 42 to move up and down, and the pressure wheel 8 rotates relative to the nail box mechanism 4.

[0056] Working principle:

[0057] The paper feeding mechanism 1 regularly feeds the cardboard 9 into the gluing rack 21, and the gluing rack 21 performs the gluing operation on the cardboard 9. The glued cardboard is first pressed with an indentation in the folding mechanism 3, and then the two sides are folded, and the two sides coated with glue are fitted together. Before entering the nail box mechanism 4, the bonding area of ​​the cardboard 9 is first pressed and bonded by the pressure wheel, and then nailed into the box nail 93 in the nail box mechanism 4. Preferably, before nailing into the box nail 93, the third telescopic device 41 drives the second baffle 42 to move downward to stop and position the cardboard 9, and cylinders can also be set on both sides for left and right positioning (structure is like the fourth telescopic device 28). After completing the nailing of the box nail 93, the stop and positioning mechanism is reset, and the cardboard 9 continues to move into the output mechanism 5, and is counted in the output mechanism 5 and leaves this device.

[0058] When nailing the box, the box nail 93 is positioned so that it passes through the blind holes of the upper and lower aligned cardboards 9. When the box nail 93 penetrates the glue, it is glued. Part of the glue is squeezed into the gap between the box nail 93 and the cardboard 9, thereby wrapping the box nail 93, preventing the box nail 93 from rusting in a humid environment and causing cracks in the joints of the carton.

[0059] Preferably, the blind hole through which the nail box nail 93 passes has a larger volume than the other blind holes, so as to accommodate more glue to wrap around the nail box nail 93. When the cardboard 9 is corrugated paper, the corrugated paper is located between two layers of linerboard. The blind hole through which the nail box nail 93 passes can pass through one layer of linerboard, allowing the glue to enter the corrugated paper between the two layers of linerboard, thereby increasing the volume of glue to better wrap around the nail box nail 93 and prevent it from overflowing into the gap.

[0060] It should be noted that the paper feeding mechanism 1 , folding mechanism 3 , box stapling mechanism 4 and output mechanism 5 are all devices of the prior art.

[0061] The present invention has been described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
