Description

Technical Field

[0001] The utility model belongs to the technical field of napkin production, in particular to a slitting device for napkin production. Background Art

[0002] Napkins, also known as tissues or facial tissues, are disposable paper products used to wipe the corners of the mouth, hands or other surfaces to keep them clean. They are usually made from wood pulp or other plant fibers through papermaking processes. They are soft, absorbent, and not easy to shed, making them very suitable for daily use.

[0003] The existing slitting device for napkin production uses a conveying device to convey the napkin blanks to be cut. During the conveying process, the electric push rod drives the slitting seat to be pressed down, and the slitting knives evenly arranged on the slitting seat realize the slitting of the napkins. However, in actual use, since napkins can be divided into many categories and the specifications of different types of napkins are different, it is necessary for personnel to spend time and energy to adjust the distance between the slitting knives, which is not conducive to personnel use. Utility Model Content

[0004] In view of this, the utility model aims to solve the deficiencies of the prior art and provides a slitting device for napkin production, which can enable the slitting knives on the left and right sides to synchronously approach or move away from the slitting knife in the middle, quickly and accurately adjust the distance between the slitting knives, and then quickly and accurately adjust the size of the napkin slitting.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a slitting device for napkin production, comprising a frame, a plurality of evenly distributed supporting feet are arranged on the lower surface of the frame, a mounting seat is arranged on the upper surface of the frame, rotating rods are rotatably arranged on the left and right sides inside the mounting seat, sprockets are fixedly sleeved on the front and back sides of the outer arc surface of the rotating rod, a plate chain conveyor belt is arranged for transmission between the four sprockets, a plurality of evenly distributed supporting rollers are rotatably arranged inside the mounting seat, the outer sides of the supporting rollers are in contact with the plate chain conveyor belt, a supporting frame is arranged on the upper side of the mounting seat, a sliding column is slidably arranged on the middle part of the upper surface of the supporting frame, a slitting seat is arranged at the bottom end of the sliding column, and a slitting seat is arranged on the lower side of the inner part of the slitting seat. Two guide rails are symmetrically distributed front and back, and a fixed seat is connected and fixed between the middle parts of the outer arc surfaces of the two guide rails. Two movable seats are symmetrically distributed left and right and are slidably arranged between the two guide rails. Two driving seats are symmetrically distributed left and right and are slidably arranged between the two guide rails. The movable seats are both located between the fixed seat and the driving seat. Slitting knives are arranged at the bottom ends of the fixed seat, the movable seat and the driving seat, and an electric control module for driving the slitting knife to move horizontally is also arranged on the slitting seat; a motor 1 is arranged on the rear side of the mounting seat, and the output shaft of the motor 1 is fixed to the adjacent rotating rod by a coupling; two electric push rods are symmetrically distributed left and right and are arranged on the upper surface of the support frame, and the telescopic ends of the electric push rods are both connected and fixed to the slitting seat.

[0006] As a further improvement of the present invention, the electric control module includes a slider symmetrically and slidably arranged on the upper side of each movable seat, a rotating shaft is rotatably arranged in the middle of the upper surface of the fixed seat, a connecting rod 1 is rotatably arranged on the lower side of the outer arc surface of the rotating shaft, and a rotating rod 2 is rotatably arranged on the upper side of the outer arc surface of the rotating shaft, the two ends of the connecting rod 1 and the rotating rod 2 are respectively rotatably connected with adjacent sliders, two driving rods staggered up and down are rotatably arranged in the middle of the upper surface of the driving seat, and the ends of the driving rods away from the driving seat are respectively rotatably connected with adjacent sliders, and an electric control unit for controlling the movement of the driving seat is also arranged on the cutting seat; the electric control unit includes a bidirectional screw screw rotatably arranged on the upper side of the inside of the cutting seat, the two driving seats are threadedly connected to the bidirectional screw screw, and a motor 2 is arranged on the left side of the cutting seat, and the output shaft of the motor 2 is fixed to the bidirectional screw screw by a coupling.

[0007] As a further improvement of the present invention, a control panel is provided on the front side of the mounting seat, and the motor 1, the electric push rod and the motor 2 are all electrically connected to the control panel.

[0008] As a further improvement of the utility model, a plurality of evenly distributed cutting pads are arranged on the outer side of the plate chain conveyor belt.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] First, place the napkins that need to be cut on the plate chain conveyor belt, which transports the napkins. When the napkins are transported to the appropriate position under the cutting seat, the control panel controls the two electric push rods to run synchronously, so that the cutting seat drives the cutting knife to press down to cut the napkins quickly and stably.

[0011] Secondly, the operation of motor 1 is regulated by the control panel, so that motor 1 drives the rotating rod connected to it to rotate, and the transmission relationship between the four sprockets and the plate chain conveyor belt drives the plate chain conveyor belt to rotate, thereby realizing stable transportation of napkins.

[0012] Thirdly, the control panel adjusts the operation of motor 2, so that the output shaft of motor 2 drives the bidirectional screw connected to it to rotate, so that the bidirectional screw drives the two drive seats threadedly connected to it to move towards each other or away from each other. Since a triangular structure is formed between the drive rod, the movable seat and the drive seat, and a scissors-braced structure is formed between the movable seat, the connecting rod one and the rotating rod two, the two drive seats drive the two movable seats to move towards each other when they move towards each other, so that the slitting knives on the left and right sides can synchronously approach or move away from the slitting knife in the middle, and the spacing between the slitting knives can be quickly and accurately adjusted, and then the size of the napkin slitting can be quickly and accurately adjusted.

[0013] Fourthly, the cutting pad can increase the friction between the napkin and the plate chain conveyor belt, and at the same time make the slitting knife contact flexibly with the plate chain conveyor belt, so that the napkin can be better cut during the slitting process.
