Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape processing, in particular to a slitting mechanism and pressure-sensitive adhesive tape processing equipment. Background Art

[0002] Hot-melt pressure-sensitive adhesive is mainly made by mixing and heating other materials such as rubber and resin. It is mainly used by applying it to the items where it is needed, and it is applied to substrates such as tissue paper and cloth to form a sticky tape.

[0003] According to a slitting mechanism and pressure-sensitive adhesive tape processing equipment disclosed in patent number CN 219926222 U, a compression spring and a pressure plate are arranged in cooperation. When the electric push rod drives the cutting knife and the pressure plate to move downward, the pressure plate first contacts the pressure-sensitive adhesive tape and applies downward pressure to the pressure-sensitive adhesive tape. The cutting knife continues to move downward through the compression spring and passes through the through hole on the pressure plate to cut the pressure-sensitive adhesive tape. However, when cutting, the device directly drives the cutting knife to descend linearly to cut the adhesive tape through the electric push rod. During the cutting process, the pressure-sensitive adhesive tape at the cutting position is easily deformed due to pulling. The shape of the adhesive tape affects the cutting quality; the pressing plate of the existing device contacts the pressure-sensitive adhesive tape before the cutting knife contacts the adhesive tape, and the bottom of the pressing plate is a flat structure. After the cutting is completed, the pressing plate needs a large force to separate from the pressure-sensitive adhesive tape, and the pressure-sensitive adhesive tape is easily pulled up due to the strong adhesion, thereby causing the adhesive tape to adhere to the pressing plate; and the existing device installs the adhesive tape after the previous step of gluing on the device for slitting, which consumes a lot of time and labor costs. For this reason, we propose a slitting mechanism and pressure-sensitive adhesive tape processing equipment. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0024] It should be noted that the adhesive tape can be conveyed by the adhesive tape conveying mechanism 2. While the adhesive tape conveying mechanism 2 is driven to convey the adhesive tape, the gluing mechanism 3 can gluing the conveyed adhesive tape, thereby improving the processing efficiency of the adhesive tape.

[0025] A slitting assembly 4 for slitting the pressure-sensitive adhesive tape is provided on the top of the base 1. The adhesive tape conveying mechanism 2 includes a conveying roller 6 and a glue coating roller 7. A fixed plate 5 is symmetrically fixedly connected to one end of the base 1, and the bottom ends between the two fixed plates 5 are rotatably connected to the conveying roller 6 and the glue coating roller 7 respectively. The glue coating roller 7 is located directly above the conveying roller 6.

[0026] It should be noted that when the utility model is used, the control system provided in the device controls the driving motor 9 to work, and the adhesive tape to be glued is conveyed between the conveying roller 6 and the glue coating roller 7 under the meshing connection of the two gears 8. When the glue coating roller 7 rotates, it drives the pulley 12 to rotate. Through the transmission connection between the two pulleys 12, the stirring shaft 11 rotates to stir the glue liquid inside the glue storage box 10. A heating element is also provided inside the glue storage box 10 for heating the glue liquid to prevent it from agglomerating. At the same time, the glue liquid in the gluing mechanism 3 flows to the outside of the glue coating roller 7 through the glue outlet, and the pressure-sensitive adhesive is stirred while the adhesive tape is conveyed. The upper surface of the adhesive tape is glued. When cutting is required, the electric telescopic rod 15 is controlled to work to move the rotating motor 16 downward. The rotating motor 16 is installed between the two support plates 20. The downward movement of the rotating motor 16 drives the support plate 20 to move downward, so that the two positioning rods 22 press down and fix the two sides of the cutting position. As the rotating motor 16 continues to move downward, the slitting knife 17 contacts the adhesive tape, and the linear module 14 is cooperated to cut the adhesive tape. After the cutting is completed, the piston rod of the electric telescopic rod 15 contracts to move the positioning rod 22 upward. Since the bottom end of the positioning rod 22 is designed in an arc shape, it can be easily separated from the adhesive tape.

[0027] The ends of the conveying roller 6 and the glue coating roller 7 are both fixedly connected with gears 8 through the fixed plate 5, and the two gears 8 are meshedly connected. A driving motor 9 is fixedly installed on the side wall of the fixed plate 5, and the output shaft end of the driving motor 9 is fixedly connected to the central axis of the gear 8.

[0028] It should be noted that the gear 8 is rotated by controlling the driving motor 9, and the conveying roller 6 and the glue coating roller 7 are rotated in opposite directions through the meshing connection between the two gears 8, so as to realize the conveying of the adhesive tape.

[0029] The gluing mechanism 3 includes a glue storage box 10, a stirring shaft 11 and a pulley 12. The glue storage box 10 is fixedly connected between the top ends of the two fixed plates 5, and the glue storage box 10 is a cylindrical structure. A loading port is provided on the top of the glue storage box 10, and a mounting cover is connected to the end of the loading port. A stirring shaft 11 is rotatably connected in the glue storage box 10. The end of the glue coating roller 7 away from the gear 8 and the end of the stirring shaft 11 are fixedly connected to the pulley 12 through the fixed plate 5, and the two pulleys 12 are connected by belt transmission. Glue outlets are equidistantly provided at the bottom of the glue storage box 10, and the glue outlets are located directly above the glue coating roller 7.

[0030] It should be noted that during the transportation of the pressure-sensitive adhesive tape by the conveying roller 6 and the glue coating roller 7, the glue liquid inside the glue storage box 10 is placed on the outside of the glue coating roller 7 through the glue outlet. During the rotation of the glue coating roller 7, the glue liquid can be evenly applied to the upper surface of the adhesive tape, so that the pressure-sensitive adhesive tape is coated with glue.

[0031] The slitting assembly 4 includes a fixed frame 13, a linear module 14, an electric telescopic rod 15, a rotating motor 16 and a slitting knife 17. The fixed frame 13 is fixedly connected to the top of the base 1, and the linear module 14 is arranged on the top of the fixed frame 13. The electric telescopic rod 15 is fixedly connected to the top of the sliding block of the linear module 14, and the piston rod end of the electric telescopic rod 15 passes through the sliding block and is connected to the rotating motor 16. The output shaft end of the rotating motor 16 is fixedly connected to the slitting knife 17. A cutting groove cooperating with the slitting knife 17 is provided at the top of the base 1 directly below the slitting knife 17.

[0034] It should be noted that, by controlling the operation of the electric telescopic rod 15, the rotating motor 16 is moved downward, and the rotating motor 16 is installed between the two support plates 20. The downward movement of the rotating motor 16 drives the support plates 20 to move downward, so that the two positioning rods 22 press down and fix the two sides of the cutting position.

[0038] It should be noted that, since the bottom end of the positioning rod 22 is designed to be arc-shaped, it can be easily separated from the adhesive tape.

[0039] A pressure-sensitive adhesive tape processing device comprises any one of the above slitting mechanisms.

[0040] It should be noted that the utility model integrates the gluing and slitting of the adhesive tape, which saves the manpower operation cost and greatly improves the processing efficiency of the adhesive tape.
