Technical Field

[0001] The present invention relates to the technical field of sanitary napkins, and particularly to a winding device for sanitary napkins. Background Art

[0002] Currently, sanitary napkins are all packaged in independent small pieces. Taking out such packaged sanitary napkins in public places will inevitably cause embarrassment. For example, in a sanitary napkin packaging structure with a tissue paper disclosed in the patent with the publication number CN206372191U, after curling the independently small-piece packaged sanitary napkin, an outer cover is sleeved outside, or it is packaged into the shape of a candy by a knotted film. Currently, the production method is to curl the sanitary napkin manually and then sleeve the outer cover, resulting in relatively low production efficiency. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a winding device for sanitary napkins.

At the front end of the machine table, there is a first conveying mechanism for conveying sanitary napkins, and a second conveying mechanism for conveying adhesive tapes is installed. The end of the second conveying mechanism is adapted to the end of the first conveying mechanism. A pressing roller mechanism for pressing the adhesive tape onto the bottom surface of the sanitary napkin is installed at the end of the second conveying mechanism and the first conveying mechanism. A third conveying mechanism is arranged on the side of the pressing roller mechanism away from the first conveying mechanism, and a winding mechanism for winding the sheet-shaped sanitary napkin into a roll shape is arranged at the end of the third conveying mechanism.

[0005] A first air suction box for adsorbing the sanitary napkin on the surface of the first conveying mechanism is arranged inside the first conveying mechanism, a second air suction box for adsorbing the adhesive tape on the surface of the second conveying mechanism is arranged inside the second conveying mechanism, and a third air suction box for adsorbing the sanitary napkin on the surface of the third conveying mechanism is arranged inside the third conveying mechanism.

[0006] The adhesive tape is in a roll shape structure, and a hanging shaft device for hanging the adhesive tape is installed on the machine table.

[0007] The pressing roller mechanism consists of an upper roller controlled to press down by a first air cylinder and a lower roller installed on the machine table. A cutter for cutting the adhesive tape is installed on the side of the lower roller close to the adhesive tape.

[0008] The winding mechanism consists of a winding motor and a winding rod group installed on the rotating shaft of the winding motor. A bending baffle is installed on the outside of the winding rod group. The winding rod group is composed of two parallel winding rods. The front end of the sanitary napkin is placed between the two winding rods and rotated. With the cooperation of the bending baffle, the sheet-shaped sanitary napkin is wound into a roll shape.

[0009] A push rod is arranged in the middle of the winding rod group.

[0010] A first detection optoelectronic device is arranged on one side of the winding mechanism close to the third conveying mechanism; a feeding detection optoelectronic device is arranged at the front end of the first conveying mechanism, and a product tail material optoelectronic device is arranged on one side of the pressure roller mechanism close to the first conveying mechanism.

[0011] Blocking strips are arranged on both sides of the first conveying mechanism.

[0019] Some embodiments of the present invention provided below will be described with reference to the drawings.

[0020] Refer to Figure 1A sanitary napkin winding device comprises a machine table 1, wherein a first conveying mechanism 2 for conveying sanitary napkins is arranged at the front end of the machine table 1, and a second conveying mechanism 4 for conveying adhesive tape is installed, the end of the second conveying mechanism 4 is adapted to the end of the first conveying mechanism 2, and the ends of the second conveying mechanism 4 and the first conveying mechanism 2 are installed with a pressing roller mechanism for pressing the adhesive tape onto the bottom surface of the sanitary napkin, a third conveying mechanism 7 is arranged on the side of the pressing roller mechanism away from the first conveying mechanism 2, and a winding mechanism 8 for winding a sheet-like sanitary napkin into a roll is arranged at the end of the third conveying mechanism 7. Compared with the manual production method, the efficiency is higher, and the production process of curling the sanitary napkin and the production process of putting a jacket on the outside of the sanitary napkin are separated, the production steps are further subdivided, redundant operations and time waste are reduced, the production process is made more efficient, and the product quality is improved.

[0021] The first conveying mechanism 2 is provided with a first suction box 3 for adsorbing the sanitary napkin on the surface of the first conveying mechanism 2, the second conveying mechanism 4 is provided with a second suction box 5 for adsorbing the adhesive tape on the surface of the second conveying mechanism 4, and the third conveying mechanism 7 is provided with a third suction box 6 for adsorbing the sanitary napkin on the surface of the third conveying mechanism 7.

[0022] The adhesive tape is in a roll-like structure, and a hanging shaft device 9 for hanging the adhesive tape is installed on the machine 1. The thickness of the adhesive tape is at least 0.1 mm, and it has a certain strength. It is adsorbed on the surface of the second conveying mechanism 4 through the second suction box 5. When the second conveying mechanism 4 is driven, the adhesive tape is pulled forward.

[0023] The pressing roller mechanism is composed of an upper roller 11 controlled by a first cylinder 10 to be pressed downward and a lower roller 12 installed on the machine platform 1. A cutter 13 for cutting the adhesive tape is installed on the side of the lower roller 12 close to the adhesive tape.

[0024] The winding mechanism 8 is composed of a winding motor and a winding rod group installed on the rotating shaft of the winding motor. A bending baffle 14 is installed on the outer side of the winding rod group. The winding rod group consists of two parallel winding rods. The front end of the sanitary napkin is placed between the two winding rods and rotated, and the sheet-like sanitary napkin is wound into a roll shape in cooperation with the bending baffle 14.

[0025] A pushing rod controlled by a second cylinder is arranged in the middle of the winding rod group.

[0026] A first detection photoelectric device 15 is provided on the side of the winding mechanism 8 close to the third conveying mechanism 7; a feeding detection photoelectric device 16 is provided at the front end of the first conveying mechanism 2, and a product tail photoelectric device 17 is provided on the side of the pressure roller mechanism close to the first conveying mechanism 2.

[0027] On both sides of the first conveying mechanism 2, there are stop strips 18 to prevent the sanitary napkin from running off during output.

[0028] At the front end of the first conveying mechanism 2, there is a placement mechanism 19 for placing single sanitary napkins. At the lower end of the placement mechanism 19, there is a single-piece automatic sheet feeding mechanism 20. The placement mechanism 19 can only pass one sanitary napkin at a time. There is a placement groove in the placement mechanism 19. The sanitary napkin is placed in the placement groove and slides towards the single-piece automatic sheet feeding mechanism 20 by gravity. Inside the single-piece automatic sheet feeding mechanism 20, there is a conveyor belt for conveying the sanitary napkin to the front end of the first conveying mechanism 2, and the sanitary napkin is conveyed to the first conveying mechanism 2.

[0029] There is friction between the conveyor belt and the sanitary napkin. When the sanitary napkin contacts the conveyor belt, it is pulled and conveyed towards the first conveying mechanism 2.

[0030] Overall production process: Production workers put sanitary napkins into the placement mechanism 19 (multiple pieces can be placed). The single sanitary napkins are conveyed to the first conveying mechanism 2 through the single-piece automatic sheet feeding mechanism 20. The feeding detection optoelectronic device 16 detects that a sanitary napkin enters the first conveying mechanism 2. When the first conveying mechanism 2 conveys the sanitary napkin to the pressure roller mechanism, it continues to convey forward. When the distance between the end of the sanitary napkin and the pressure roller mechanism is 10 - 30 millimeters, the second conveying mechanism 4 drives, pulling the adhesive tape forward until the adhesive tape contacts the bottom of the sanitary napkin. The first conveying mechanism 2 and the second conveying mechanism 4 continue to drive. The pressure roller mechanism presses the sanitary napkin and the adhesive tape together. When the product tail material optoelectronic device 17 detects that the sanitary napkin completely passes through the pressure roller mechanism, the second conveying mechanism 4 continues to drive for 10 - 30 millimeters. The cutter 13 is activated to cut the adhesive tape. At the same time, the second conveying mechanism 4 stops driving, and the pressure roller mechanism continues to rotate, conveying the sanitary napkin to the third conveying mechanism 7. The third conveying mechanism 7 conveys the sanitary napkin to the winding mechanism 8. When the first detection optoelectronic device 15 detects that the sanitary napkin enters between the winding rods, the winding motor is started, and in cooperation with the bending baffle 14, the sheet-shaped sanitary napkin is wound into a roll shape. Finally, the roll-shaped sanitary napkin is pushed out by the push rod, collected by the worker, and put into the sanitary napkin packaging, thus completing one production.

[0031] The length of each piece of adhesive tape is 20 - 60 millimeters. Half of it is pasted at the end of the sanitary napkin, and the other half protrudes from the end of the sanitary napkin. After being wound by the winding mechanism 8, the protruding part is pasted on the outermost side of the roll-shaped sanitary napkin, fixing the end of the sanitary napkin to the side wall of the roll-shaped sanitary napkin and shaping it.

[0032] The front end of the placement mechanism 19 can be connected to a sanitary napkin production line, further improving automation and production efficiency.

[0033] After the push rod pushes out the roll-shaped sanitary napkin, it can be directly packaged, or after collection, it can be transported to the next process and then packaged in the same way, realizing modular production and improving production efficiency.
