Description

Technical Field

[0001] This utility model relates to the field of diaper production, specifically to an arc-shaped cutting device for diaper production. Background Technology

[0002] The production of disposable diapers involves multiple steps, from the preparation of raw materials to the packaging and quality inspection of the final product. During the production process, the folded diapers need to be cut with concave arcs on both sides to accommodate the comfort of the legs when wearing them. The arc cutting device used in the arc cutting process is an indispensable production component in disposable diaper production equipment.

[0003] Traditional cutting devices generate waste that is not cleaned up in time and accumulates on the workbench, affecting cutting efficiency. They can only cut one side of the diaper at a time in an arc shape, which is inefficient. Moreover, most of the operations in the process are still done manually, resulting in high production costs and high labor intensity for personnel. They cannot achieve automated loading and unloading and automated cutting. Utility Model Content

[0004] To address the issues of waste residue being accumulated on the workbench during cutting, affecting cutting efficiency, the inability to perform arc-shaped cutting on only one side of the diaper at a time (resulting in low efficiency), and the fact that most operations are still manual, leading to high production costs and labor intensity, and the inability to achieve automated loading and unloading and automated cutting, this invention provides an arc-shaped cutting device for diaper production.

[0005] A curved cutting device for diaper production includes a worktable with a conveyor belt rotatably mounted on it for conveying diapers. A support frame is fixedly mounted on the worktable, and cutting plates are symmetrically arranged on both sides of the support frame. Each cutting plate includes a curved cutting groove and an inclined guide plate. A limit frame is also provided next to the cutting plate, and the limit frame includes a through-hole with an arc-shaped opening that overlaps with the outer end of the arc-shaped cutting groove. Several rotating cylinders are arranged inside the limit frame. A set of electric telescopic rods and a set of object sensors are fixedly mounted on the top of the support frame. Each telescopic end of the electric telescopic rods is fixedly equipped with a curved cutting blade, which is adapted to the arc-shaped cutting groove.

[0006] Furthermore, a servo motor is mounted on the outer wall of the workbench via a mounting bracket, and conveyor rollers are rotatably mounted at both ends of the workbench. The conveyor rollers are compatible with the conveyor belt and can drive it to transport materials. One of the conveyor rollers is fixedly connected to the output shaft of the servo motor. A control panel is fixedly mounted on the top wall of the support frame. The control panel is electrically connected to the servo motor, a set of electric telescopic rods, and a set of object sensors.

[0007] Furthermore, the top wall of the arc-shaped cutting groove in the cutting plate is flush with the top wall of the conveyor belt, and the inclined upper end of the inclined guide plate is fixedly set on the side wall of the arc-shaped cutting groove, which can guide the cut diaper waste to its inclined lower end.

[0008] Furthermore, the limiting frame is arranged parallel to the conveyor belt, and the inner sidewalls of the two limiting frames are fixedly provided with grooves. The rotating drum includes a central shaft that is rotatably set between the top and bottom walls of the groove. An outer cylinder is fixedly set on the outer wall of the central shaft, and an arc-shaped through hole is provided through the top and bottom walls of the groove.

[0009] Furthermore, the curved cutting blade is positioned directly above the curved cutting groove, and a set of object sensors are positioned directly above the waist and bottom ends of the diaper.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the cutting scheme steps can be preset on the control panel, so that the device can automatically cut according to the preset steps. The diaper is placed on the conveyor belt, with both ends just in contact with the rotating drum, which plays a fixed and limiting role to avoid displacement during cutting. Then, when the object sensor senses that the diaper has entered the cutting area, the electric telescopic rod is activated to drive the two arc-shaped cutting blades through the arc-shaped cutting groove to cut both sides of the diaper at the same time, which improves the degree of automation and cutting efficiency. The waste generated during cutting can be guided away from the worktable along the inclined guide plate, and a waste collection frame can be placed under the inclined guide plate.

The following will refer to the accompanying drawings. Figures 1-5 The present invention will be described in detail with reference to the embodiments.

[0022] An arc-shaped cutting device for diaper production includes a workbench 1, a conveyor belt 2 rotatably mounted on the workbench 1 for conveying diapers, a servo motor 13 mounted on the outer wall of the workbench 1 via a mounting bracket, and conveyor rollers 14 rotatably mounted at both ends of the workbench 1. The conveyor rollers 14 are adapted to the conveyor belt 2 and can drive it to convey diapers. One of the conveyor rollers 14 is fixedly connected to the output shaft of the servo motor 13.

[0023] The folded diapers are manually placed on the conveyor belt 2, so that the two sides of the diapers come into contact with the rotating drum 9 to form a limit. Alternatively, the conveyor belt 2 can be connected with the discharge conveyor belt in the previous diaper folding step to form an automated feeding for cutting. The servo motor 13 is started, driving the conveyor rollers 14 to rotate. The outer walls of the two conveyor rollers 14 are adapted to the inner wall of the conveyor belt 2, which can drive the conveyor belt 2 to achieve automatic conveying.

[0024] A support frame 3 is fixedly installed on the workbench 1. Cutting boards 4 are symmetrically arranged on both sides of the support frame 3. A set of electric telescopic rods 10 and a set of object sensors 11 are fixedly installed at the top of the support frame 3. The set of object sensors 11 are respectively located directly above the waist and bottom ends of the diaper. A control panel 15 is fixedly installed on the top wall of the support frame 3. The control panel 15 is electrically connected to the servo motor 13, the set of electric telescopic rods 10 and the set of object sensors 11.

[0025] The various processes and steps of cutting can be preset on the control system inside the control panel 15. Only when the waistband and crotch of the diaper are simultaneously within the sensing areas of the two object sensors 11 will a set of object sensors 11 transmit the sensed information to the control panel 15. The control panel 15 will then issue a pause instruction to the servo motor 13, so the conveyor belt 2 will temporarily stop conveying and the electric telescopic rod 10 will be instructed to extend downward for cutting, so that the arc-shaped cutting blade 12 can perform arc-shaped cutting on the diaper below.

[0026] Each of the telescopic ends of a set of electric telescopic rods 10 is fixedly equipped with an arc-shaped cutting blade 12. The arc-shaped cutting blade 12 is adapted to the arc-shaped cutting groove 5. The arc-shaped cutting blade 12 is positioned directly above the arc-shaped cutting groove 5. The control panel 15 controls the simultaneous activation of the set of electric telescopic rods 10, which drives the arc-shaped cutting blade 12 to approach the arc-shaped cutting groove 5 below. The outer end of the arc-shaped cutting blade 12 passes through the arc-shaped through hole 8 and continues to cut downwards until the arc-shaped cut on both sides of the diaper is completed on the arc-shaped cutting groove 5. The cutting efficiency is high.

[0027] The cutting plate 4 includes an arc-shaped cutting groove 5 and an inclined guide plate 6. The top wall of the arc-shaped cutting groove 5 in the cutting plate 4 is flush with the top wall of the conveyor belt 2. The inclined upper end of the inclined guide plate 6 is fixedly set on the side wall of the arc-shaped cutting groove 5, which can guide the cut diaper waste to its inclined lower end.

[0028] The arc-shaped cutting groove 5 facilitates the arc-shaped cutting blade 12 to cut the diapers in an arc shape. The waste material cut off from the diapers slides down the inclined guide plate 6 from the upper inclined end to the lower inclined end. A waste material collection box can be placed at the lower inclined end to collect the cut waste material. Then, a finished diaper collection box is placed below the tail of the conveyor belt 2 to collect the cut diapers.

[0029] Next to the cutting board 4, a limiting frame 7 is also provided. The limiting frame 7 includes an arc-shaped through hole 8 that runs through the board. The arc-shaped through hole 8 overlaps with the outer end of the arc-shaped cutting groove 5. The outer end of the arc-shaped cutting blade 12 passes through the arc-shaped through hole 8 and falls into the arc-shaped cutting groove 5 below for cutting.

[0030] The limiting frame 7 is arranged parallel to the conveyor belt 2 to limit the two sides of the diaper, preventing it from shifting on the conveyor belt 2 and affecting the cutting result. The inner sidewalls of the two limiting frames 7 are fixedly provided with grooves 16. Several rotating cylinders 9 are provided inside the limiting frame 7. The rotating cylinder 9 includes a central shaft 17 that is rotatably set between the top wall and the bottom wall of the groove 16. An outer cylinder 18 is fixedly set on the outer wall of the central shaft 17. An arc-shaped through hole 8 is provided through the top wall and the bottom wall of the groove 16.

[0031] The two side walls of the diaper are in contact with the outer tube 18. Under the transmission action of the conveyor belt 2, the drum 9 is driven to rotate forward when it is conveyed forward. This can reduce the friction on the sides of the diaper while limiting the position, and speed up the conveying speed.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
