[0002] Paper bubble envelopes are a type of express packaging bag that uses bubble paper as an inner lining to protect mailed items from damage. Paper bubble envelopes are usually used to mail items that need protection, such as books, clothing, and electronic products. The bubble paper lining can effectively alleviate the vibration and impact generated during transportation, thereby protecting the items from damage.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The invention relates to a bag opening gluing device for a paper bubble envelope. The method comprises the following steps: placing the paper bubble envelope bag on a conveying platform and starting a transmission machine to drive the envelope bag to move to the other end, and simultaneously starting a heater to heat a hot pressing roller to increase its temperature. During the movement of the envelope bag, the envelope bag moves to the bottom of the rotating roller and pushes a connecting arm to move upward under the limit of a lifting rod. Meanwhile, the moving envelope bag drives the rotating roller to rotate. Since a heated hot pressing roller is arranged on the rotating roller, the hot pressing roller will rotate along with the rotating roller and roll over the bag opening of the envelope bag during the rotation process. Since the temperature of the hot pressing roller is relatively high, the bubble layer at the bag opening of the envelope bag will shrink rapidly after contacting the hot pressing roller. After the paper bubble envelope bag passes through the hot pressing under the pressing mechanism, the hot pressing part can be glued by using a gluing roller and a slitting roller. The device is convenient for improving the tightness of gluing at the bag opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 4 A first fixing nut 201 is threadedly sleeved on the screw rod 2, a second fixing nut 202 is threadedly sleeved on the screw rod 2, a bottom end of the screw rod 2 is fixedly connected to a bottom plate 203, a sleeve 204 is slidably sleeved on the outside of the bottom end of the screw rod 2, a first spring 205 is arranged inside the sleeve 204, a rotating block 206 is fixedly connected to the bottom of the sleeve 204, a pressure seat 207 is rotatably connected to the rotating block 206, a rotating groove 208 is opened on the top of the pressure seat 207, a rotating wheel 209 is rotatably connected to the bottom of the pressure seat 207, the first fixing nut 201 is arranged on the upper surface of the protective cover 102, the second fixing nut 202 is arranged on the lower surface of the first fixing nut 201, the first spring 205 is movably sleeved on the screw rod 2, and the rotating block 206 is rotatably connected to the inside of the rotating groove 208.

[0028] By setting a pressure seat 207 and a rotating wheel 209, the envelope bag can be pressed and fixed when the pressing mechanism 3 performs heat pressing on the bag mouth of the envelope bag. By setting a first fixing nut 201 and a second fixing nut 202, the positions of the pressure seat 207 and the rotating wheel 209 can be adjusted to adapt to paper bubble envelope bags of different thicknesses.

[0029] Working principle: when a bag-mouth gluing device for a paper bubble envelope is used, in the initial state, first, the control panel 103 is installed on one side of the conveying platform 1 through the rear case 101, and the gluing roller 106 and the slitting roller 107 arranged on the inner side of the rear case 101 are rotatably connected above the conveying platform 1, so as to facilitate gluing the paper bubble envelope bag. At the same time, a screw 2 is installed on the protective cover 102 arranged on one side of the rear case 101, and the sleeve 204 and the rotating block 206 at the bottom of the screw 2 are connected with the pressing seat 207 and the rotating wheel 209 through the rotating groove 208, so as to facilitate pressing and fixing the envelope bag. At the same time, the fixed plate 301 arranged on the inner side is connected to the connecting arm 303 through the lifting rod 302, and the connecting arm 303 is rotatably connected with the rotating roller 305 and the hot pressing roller 306, and the outer side of the hot pressing roller 306 is provided with a heater 308, so as to heat the hot pressing roller 306 to heat the bag mouth;

[0030] When it is necessary to improve the tightness of gluing the bag opening, first place the paper bubble envelope bag on the conveyor platform 1 and start the conveyor 104 to drive the envelope bag to move to the other end. At the same time, start the heater 308 to heat the hot pressing roller 306 to make it warm up.

Since the rotating roller 305 is provided with a heated hot pressing roller 306, the hot pressing roller 306 will also rotate during the rotation of the rotating roller 305 and roll over the bag opening of the envelope bag. Since the temperature of the hot pressing roller 306 is relatively high, the bubble layer of the bag opening of the envelope bag will shrink rapidly after contacting the hot pressing roller 306. After the paper bubble envelope bag passes through the hot pressing from the bottom of the pressing mechanism 3, the hot pressing area can be glued using the gluing roller 106 and the slitting roller 107. This device is convenient for improving the tightness of gluing the bag opening.
