Specifically, the lateral wall of the box body 11 is provided with a drawing box 15, the drawing direction of the drawing box 15 is perpendicular to the conveying direction of the strip-shaped kraft paper 2, a preset position in the drawing box 15 is used for placing a conical flask, and after the drawing box 15 is pushed into the box body 11, the conical flask is located under one of the round kraft paper 21.

More specifically, as shown in fig. 3, a filling plate 151 made of foam or sponge is disposed in the drawing box 15, a placing groove 152 is disposed at the top of the filling plate 151, the bottom of the placing groove 152 completely penetrates through the filling plate 151, and the placing groove 152 is used for matching with the erlenmeyer flask, so that the erlenmeyer flask is ensured to be placed at a preset position and cannot move in the packaging process.

Specifically, the covering assembly is arranged above the box body 11 and used for pressing one of the round kraft paper 21 downwards so as to cover the bottle mouth of the conical bottle. The package of tying locates 11 tops of box, including 3 at least manipulators, be used for pulling open stretch cord 31, make its round kraft paper 21 of constraint bottleneck, during the concrete use, three position on the clamping part centre gripping stretch cord 31 of 3 manipulators, then stretch cord 31 is outwards pulled open to the level, again with stretch cord 31 downstream to the bottleneck department of erlenmeyer flask, and the bottleneck is located stretch cord 31, the manipulator gathers together earlier this moment, when the nearly round kraft paper 21 of soon, stretch cord 31 is loosened to the clamping part, thereby constraint round kraft paper 21. Need to explain: the manipulator can be a six-axis robot and other conventional structures, is not shown in the attached drawings, and the clamping part also belongs to the conventional structures, for example, a power part and two clamping hands are arranged, and the power part adjusts the opening and closing of the two clamping hands.

When the scheme is implemented, the pulling box 15 is pulled out, the conical bottle to be packaged is placed at the preset position of the pulling box 15, and after the pulling box 15 is pushed in, the conical bottle is just positioned under one round kraft paper 21; under the action of the coating component, the round kraft paper 21 is pressed downwards to be separated from the strip kraft paper 2, and the round kraft paper 21 is coated on the bottle mouth of the conical bottle; under the action of the manipulator, the round kraft paper 21 is bound by the elastic rope 31. In the process, the kraft paper does not need to be manually packaged and bound.

In order to facilitate the mechanical arm to clamp the elastic rope 31, the elastic rope 31 needs to be arranged at a specific position in advance, and the specific way is as follows: as shown in fig. 4, prick a mouthful subassembly and still include runner 32, third motor 33, runner 32 center one side normal running fit in first support, third motor 33 output shaft is connected to the center opposite side, the second support is located to third motor 33, first support, the second support is all connected in box 11, third motor 33 drive runner 32 makes it rotate in vertical plane, runner 32 is located directly over one of them circular kraft paper 21, runner 32 periphery evenly distributed has a plurality of pieces of strutting, every piece of strutting includes three evenly distributed's the board 34 that struts, the centre of a circle of three board 34 that struts is located the same point, two adjacent board 34 that strut have the interval of predetermineeing, stretch cord 31 overlaps in three board 34 periphery that struts.

When the device is used, the third motor 33 drives the rotating wheel 32 to enable one of the strutting pieces to be located at the lowest position, at the moment, the lowest strutting piece is vertically downward, and the elastic rope 31 on the lowest strutting piece is horizontal; then 3 mechanical hands act on the elastic rope 31 at the lowest position from the space of the opening plates 34 respectively, and the mechanical hands horizontally open the elastic rope 31 outwards; when the elastic rope 31 is separated from the opening plate 34, the manipulator moves the elastic rope 31 downwards to the bottleneck of the conical flask; the robot is gathered up first, and when the robot approaches the circular kraft paper 21, the clamping part of the robot loosens the elastic rope 31, thereby binding the circular kraft paper 21.

the using stage is that the conical flask is placed at a preset position in the drawing box (15); the first lifting piece (42) extends to enable the two limiting rings (41) to fix the strip-shaped kraft paper (2); the second lifting piece (22) extends to enable the two lower pressing rings (24) to press down the circular kraft paper (21) positioned in the two limiting rings (41), and the circular kraft paper (21) is coated on the bottle mouth of the conical bottle; the 3 manipulators act on the elastic ropes (31) from the space between the opening plates (34), the elastic ropes (31) are pulled open and then move downwards to the bottle mouth, and the manipulators loosen the elastic ropes (31) to enable the manipulators to bind the circular kraft paper (21); taking out the conical flask from the pull box (15);

a reset stage: resetting the manipulator; the second expansion piece (23) is shortened to enable the lower pressing ring (24) to be separated from the bottle opening, the second lifting piece (22) is shortened, and the second expansion piece (23) is extended to enable the lower pressing ring (24) to reset; the first lifting piece (42) is shortened to enable the limiting ring (41) to loosen the strip-shaped kraft paper (2); the next round kraft paper (21) is conveyed to a preset position under the driving of the first motor and the second motor; the third motor (33) drives the wheel (32) so that the next spreader is located at the lowermost part of the wheel (32).

8. Method for the automatic packaging of bottle mouths according to claim 7, characterized in that the preparation phase: the method comprises the steps that the strip-shaped kraft paper (2) on the feeding roller (12) is unfolded to the tops of two adjusting rollers (13), then the strip-shaped kraft paper is inserted between two clamping plates (142) from the gap of an arc-shaped plate (141), a first telescopic piece (144) extends to enable the two clamping plates (142) to clamp the end portions of the strip-shaped kraft paper (2), and a first motor and a second motor respectively drive the feeding roller (12) and the receiving roller (14) to enable the first round kraft paper (21) to be conveyed to a preset position.
