Description

Technical Field

[0001] The utility model relates to the technical field of hole punching machines, in particular to a hole punching machine for producing nursing pads. Background Art

[0002] The hole punching machine in the production of nursing pads is used to punch holes in the padding to enhance its water absorbency and breathability. As the requirements for the comfort and performance of nursing pads increase, the research and development of hole punching machines are constantly improving to achieve more efficient and precise punching effects and enhance the overall function of the nursing pads.

[0003] However, in actual use, the following deficiencies still exist, such as: the existing hole-punching machine for producing nursing pads cannot ensure that the nursing pads are flat and wrinkle-free during the hole-punching operation. The hole-punching machine punches holes in the nursing pads to improve their absorption performance. However, if there are wrinkles on the nursing pads, the positions of the holes may not be accurately controlled, resulting in poor absorption effect. In addition, wrinkles may also hinder the flow of liquid in the nursing pads, further affecting the absorption performance. If the hole-punching machine cannot ensure that the nursing pads are flat and wrinkle-free, then additional processes are required to deal with these wrinkles, such as ironing and pressing. These additional processes not only increase production costs, but may also extend the production cycle.

[0004] Therefore, the utility model proposes a nursing pad production hole-dotting machine to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1-Figure 3 As shown, this embodiment provides a technical solution: a nursing pad production hole-dotting machine, comprising a base plate 1, a hole-dotting assembly 2 provided on the base plate 1, a tensioning assembly 3 provided on the base plate 1, and an adjustment assembly 4 provided on one side of the base plate 1 close to the hole-dotting assembly 2;

[0032] like Figure 1-Figure 2As shown, the hole-dotting assembly 2 includes a bracket 21, a fixed plate 22 is fixedly connected to the bracket 21, a first connecting plate 24 is slidably connected to the fixed plate 22, a first connecting rod 25 is fixedly connected to the first connecting plate 24, a second connecting rod 26 is fixedly connected to the first connecting plate 24, a second connecting plate 28 is fixedly connected to the first connecting rod 25, a third connecting plate 210 is fixedly connected to the second connecting rod 26, a first telescopic spring 29 is provided on the second connecting rod 26, a hole-dotting needle 211 is fixedly connected to the third connecting plate 210, and a first roller 213 is rotatably connected to the bracket 21;

[0033] like Figure 1 as well as Figure 3-Figure 4 As shown, the adjustment component 4 includes a screw 42 and a fixed block 44, the screw 42 is threadedly connected to a moving block 43, the fixed block 44 is slidably connected to a moving rod 45, the moving block 43 is fixedly connected to the moving rod 45, the fixed block 44 is rotatably connected to a first rotating block 46, the first rotating block 46 is rotatably connected to a second rotating block 47, the moving block 43 is rotatably connected to a third rotating block 48, the other end of the third rotating block 48 is rotatably connected to the second rotating block 47, the second rotating block 47 is rotatably connected to a fourth roller 49, the operator starts the third transmission motor 41, and its output end drives the screw 42 to rotate. As the screw 42 rotates, the moving block 43 begins to move smoothly along a preset trajectory, thereby pushing the moving rod 45 and the third rotating block 48 connected thereto to move synchronously. This action triggers the linkage mechanism between the second rotating block 47 and the fourth roller 49, so that they It can rotate smoothly. In this way, the fourth roller 49 effectively applies uniform pressure to the surface of the nursing pad, thereby achieving the effect of leveling and tensioning, ensuring that the nursing pad remains in the best condition before entering the next process. Then, the operator activates the electric telescopic rod 23 and the first transmission motor 212. The two work together to prompt the first roller 213 to slowly but steadily transport the leveled nursing pad to a position directly below the third connecting plate 210. At this time, the pre-set perforating needle 211 accurately penetrates the material to complete the precise punching task. The whole process is smooth and efficient, which not only greatly improves production efficiency, but more importantly, solves the problem of uneven position or uneven arrangement of holes caused by uneven nursing pads in traditional methods, ensuring the quality consistency and aesthetics of the final product, thereby solving the technical problem of uneven offset of holes caused by uneven nursing pads during perforation work.

[0034] The above solutions also have the problem that the tension of the nursing pad cannot be satisfied when the nursing pad is stretched. Figure 1-Figure 2As shown: an electric telescopic rod 23 is installed on the fixed plate 22, the first connecting plate 24 is fixedly connected to the output end of the electric telescopic rod 23, the fixed plate 22 is fixedly connected to the limiting plate 27, the first connecting rod 25 is slidably connected in the limiting plate 27, and the second connecting rod 26 is slidably connected in the limiting plate 27. Since the electric telescopic rod 23 is installed on the fixed plate 22, and the first connecting plate 24 is fixedly connected to the output end of the electric telescopic rod 23, when the electric telescopic rod 23 is started, the output end of the electric telescopic rod 23 can drive the first connecting plate 24 to move. Since the fixed plate 22 is fixedly connected to the limiting plate 27, the first connecting rod 25 is slidably connected in the limiting plate 27, and the second connecting rod 26 is slidably connected in the limiting plate 27, so that the limiting plate 27 can limit the movement of the first connecting rod 25 and the limiting plate 27, preventing the first connecting rod 25 and the second connecting rod 26 from deviating during movement. One end of the first telescopic spring 29 is fixedly connected to the second connecting plate 28. The other end of 9 is fixedly connected to the third connecting plate 210, and the second connecting plate 28 is slidably connected to the second connecting rod 26. The first transmission motor 212 is installed on the bracket 21, and the first roller 213 is fixedly connected to the output end of the first transmission motor 212. Since one end of the first telescopic spring 29 is fixedly connected to the second connecting plate 28, and the other end of the first telescopic spring 29 is fixedly connected to the third connecting plate 210, the hole-dotting assembly 2 can play a buffering role when performing a hole-dotting operation on the nursing pad to prevent the nursing pad from being damaged by excessive downward pressure. Since the second connecting plate 28 is slidably connected to the second connecting rod 26, the cooperation of the second connecting plate 28 and the first telescopic spring 29 can provide a buffering effect. Since the first transmission motor 212 is installed on the bracket 21, and the first roller 213 is fixedly connected to the output end of the first transmission motor 212, when the first transmission motor 212 is started, the output end of the first transmission motor 212 can drive the first roller 213 to rotate;

[0035] like Figure 1 as well as Figure 3As shown, the tensioning assembly 3 includes a first support frame 31 and a second support frame 34, the first support frame 31 is fixedly connected to the base plate 1, a second transmission motor 32 is installed on the first support frame 31, and a second roller 33 is fixedly connected to the output end of the second transmission motor 32, the second support frame 34 is fixedly connected to the base plate 1, a limiting rod 35 is fixedly connected inside the second support frame 34, a slider 36 is slidably connected to the limiting rod 35, a second telescopic spring 37 is provided on the limiting rod 35, one end of the second telescopic spring 37 is fixedly connected to the second support frame 34, and the other end of the second telescopic spring 37 is fixedly connected to the slider 36, and a third roller 38 is rotatably connected to the slider 36. The operator places the nursing pad roll on the second roller 33, and the nursing pad is stretched to pass through the third roller 38, the fourth roller 49 and the first transmission motor 212. Through the cooperation of the provided limiting rod 35, the slider 36 and the second telescopic spring 37, the third roller 38 can be fine-tuned up and down to adapt to the tension generated by the nursing pad during processing;

[0036] like Figure 1 as well as Figure 3-Figure 4 As shown, a third transmission motor 41 is installed on the base plate 1, a screw 42 is fixedly connected to the output end of the third transmission motor 41, and a fixed block 44 is fixedly connected to the base plate 1. Since the third transmission motor 41 is installed on the base plate 1 and the screw 42 is fixedly connected to the output end of the third transmission motor 41, when the third transmission motor 41 is started, the output end of the third transmission motor 41 will drive the screw 42 to rotate. Since the fixed block 44 is fixedly connected to the base plate 1, the base plate 1 can support and fix the fixed block 44.

[0037] Working principle:

[0038] like Figures 1-4As shown, first, the operator places the nursing pad roll on the second roller 33, and the nursing pad is stretched through the third roller 38, the fourth roller 49 and the first transmission motor 212. Through the cooperation of the set limit rod 35, the slider 36 and the second telescopic spring 37, the third roller 38 can be fine-tuned up and down to adapt to the tension generated by the nursing pad during processing. Then, the operator starts the third transmission motor 41, and its output end drives the screw 42 to rotate. As the screw 42 rotates, the moving block 43 begins to move smoothly along the preset trajectory, thereby pushing the moving rod 45 and the third rotating block 48 connected thereto to move synchronously. This action triggers the linkage mechanism between the second rotating block 47 and the fourth roller 49, allowing them to rotate smoothly. In this way, the fourth roller 49 effectively applies uniform pressure to the surface of the nursing pad, thereby achieving the effect of leveling and tensioning, ensuring that the nursing pad remains in the best condition before entering the next process. Then, the operator activates the electric telescopic rod 23 and the first transmission motor 212. The two work together to prompt the first roller 213 to slowly but steadily transport the leveled nursing pad to a position directly below the third connecting plate 210. At this time, the pre-set perforating needle 211 accurately penetrates the material to complete the precise punching task, which not only greatly improves production efficiency, but more importantly solves the problem of hole position offset or uneven arrangement caused by the unevenness of the nursing pad in the traditional method, ensuring the quality consistency and aesthetics of the final product.
