[0002] With the rapid development of the hygiene products market, consumers have higher and higher requirements for hygiene products. As a key part of hygiene products, the absorbent core layer plays a role in absorbing and storing a large amount of liquid. The quality of its performance directly affects the liquid absorption quality and use time of hygiene products.

[0003] An existing absorbent core layer includes an upper layer, a middle layer and a lower layer. The middle layer is provided with a through hole connecting the upper and lower layers. The horizontal cross-section of the through hole gradually increases from the upper layer to the lower layer, that is, a conical hole or a teardrop-shaped hole is formed to improve the permeability. The middle layer material is a foaming material. In order to process the conical hole in the middle layer, it is generally mainly formed by puncturing with a heated needle. When the needle pierces the middle layer, the conical or teardrop-shaped hole is formed by hot-scalding the middle layer material. In order to facilitate the processing of this product, the existing processing method is relatively cumbersome. Therefore, a device that can make a needle-punch hole in the middle layer of the product is to be developed. Summary of the invention

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 4 The present embodiment provides a shell 1, a puncturing mechanism 2 is arranged inside the shell 1, a pad 3 adapted to the puncturing mechanism 2 is installed in the shell 1, a heating element 4 is installed on the side of the puncturing mechanism 2 away from the pad 3, the puncturing mechanism 2 includes a puncture assembly 21, connecting rods 22 are fixedly installed on both sides of the puncture assembly 21, a driving unit 23 for driving the connecting rod 22 to rotate is fixedly installed on the surface of the connecting rod 22, and a driving element 24 for driving the puncture assembly 21 to move toward the pad 3 is installed on the connecting rod 22.

[0018] Because the middle layer of the absorbent core layer is a special core layer, it is provided with multiple conical holes inside. The formation process of the holes is as follows: First, the absorbent core layer to be processed, which we refer to as the sanitary napkin core here, that is, the sanitary napkin is placed on the pad 3, wherein the heating element 4 heats the needle-punching component 21, and the heated needle-punching component 21 is driven to move through the driving unit 23 and the connecting rod 22, so that the heated part of the needle-punching component 21 is flipped to the same side as the sanitary napkin. At this time, the driving element 24 drives the needle-punching component 21 to move toward the sanitary napkin, so that the heated needle-punching component 21 punctures the sanitary napkin, and then the driving unit 23 moves the needle-punching component 21 to the heating element 4 again for heating. After the sanitary napkin is punctured, the needle-punching component 21 is driven away from the sanitary napkin, and then the next unprocessed sanitary napkin is guided to move onto the pad 3 to wait for the processing of the needle-punching component 21.

[0019] See also Figure 3 and Figure 4 The acupuncture assembly 21 includes a shaft cylinder 211, a connecting rod 22 fixedly mounted on the axial side of the shaft cylinder 211, wherein the axis of the connecting rod 22 coincides with the axis of the shaft cylinder 211, and four thorn plates 212 are fixedly mounted on the circumferential side of the shaft cylinder 211, and the four thorn plates 212 are evenly distributed around the circumference of the shaft cylinder 211.

[0020] The shaft cylinder 211 is driven to rotate by the rotation of the connecting rod 22, that is, the pricking plate 212 on the shaft cylinder 211 is driven to rotate. When the workpiece heats the acupuncture assembly 21, that is, the tips of the pricking needles sprinkled on the pricking plate 212 are heated by the heating element 4, and then the heated pricking plate 212 is rotated to a position opposite to the backing plate by the driving unit 23, and then the pricking plate 212 is driven by the driving element 24 to perform pricking and ironing processing on the sanitary napkin.

[0021] See also Figure 4 The driving unit 23 includes a rack 231 fixedly mounted on the inner wall of the housing 1 , and a ratchet 232 meshing with the rack 231 is fixedly mounted on the side surface of the connecting rod 22 .

[0022] Through the mutual cooperation between the ratchet and the rack 231, when the acupuncture assembly 21 moves toward the pad 3, the ratchet 232 engages with the rack 231 to drive the connecting rod 22 to rotate. When the acupuncture assembly 21 moves away from the pad 3, the ratchet 232 engages with the rack 231 and the connecting rod 22 does not rotate. Therefore, when the pricking plate 212 has finished processing the sanitary napkin, the driving member 24 drives the pricking assembly 21 to move in the direction of the heating member 4, that is, drives the pricking assembly 21 to move in the direction away from the pad 3, and the pricking assembly 21 does not rotate, thereby driving the pricking plate 212 away from the side of the pad 3 to move in the direction of the heating member 4, so that the pricking needles on the pricking plate 212 are heated. When the driving member 24 drives the pricking assembly 21 to move in the direction of the pad 3, the ratchet 232 and the rack 231 are engaged, and the pricking assembly 21 rotates, thereby rotating the pricking plate 212 that has been heated to a position opposite to the pad 3, and the sanitary napkin that has been processed once will move to the upper side of the pricking assembly 21, waiting for the heating member 4 to heat again. As the driving member 24 continues to move, the pricking plate 212 processes the surface of the sanitary napkin. After the processing is completed, the driving member 24 moves again and repeats the above operation, thereby achieving the effect of scalding and pricking the surface of the sanitary napkin.

[0023] See also Figure 3 and Figure 4The driving member 24 includes a slide rail 241 and an electric slider 242. The electric slider 242 is slidably mounted on the slide rail 241. A kit 243 is fixedly mounted on the electric slider 242. The kit 243 is sleeved on the surface of the connecting rod 22. The electric slider 242 moves on the slide rail 241, thereby driving the connecting rod 22 to move through the kit 243, thereby driving the acupuncture assembly 21 to move.

[0024] In the process of the needling assembly 21 being driven to rotate by the ratchet and the rack 231, there is a gap between the ratchet and the rack 231, and when the ratchet and the rack 231 are engaged to drive the needling assembly 21 to rotate, the inertia of the needling assembly 21 will cause the needling assembly 21 to deviate by a certain angle. When the pricking plate 212 processes the sanitary napkin on the pad 3, the needles on the pricking plate 212 are not perpendicular to the pad 3, affecting the puncturing effect.

[0025] See also Figure 4 and Figure 5 To solve the above technical problems, the position of the pricking plate 212 is corrected after the acupuncture assembly 21 is rotated. A square block 25 is fixedly installed on the side of the connecting rod 22 away from the acupuncture assembly 21, and a correction hole 26 is opened on the side of the square block 25. A guide groove 27 is opened on the side of the square block 25. A first plug rod 28 is fixedly installed on the inner wall of the housing 1. When the ratchet is located between the rack 231 and the pad 3, the first plug rod 28 is located in the correction hole 26.

[0026] When the driving member 24 drives the pricking assembly 21 to move in the direction of the pad 3, the ratchet first contacts the rack 231. When the two are meshed, the ratchet drives the connecting rod 22 and the pricking assembly 21 to rotate, thereby transferring the heated pricking plate 212 to a position opposite to the pad 3. As the driving member 24 drives the pricking assembly 21 to continue to move, the square block 25 on the connecting rod 22 gradually approaches the first insertion rod 28. If an angle deviation occurs after the rotation of the pricking assembly 21 is completed, the square block 25 will first contact the inner wall of the guide groove 27 when contacting the first insertion rod 28. Under the interaction force between the guide groove 27 and the first insertion rod 28, the pricking assembly 21 with a deflected angle will be gradually corrected. After the pricking assembly 21 is corrected, that is, the needles on the pricking plate 212 are perpendicular to the pad 3, at this time, the first insertion rod 28 can just be inserted into the correction hole 26, thereby limiting the rotation of the square block 25, the connecting rod 22 and the pricking assembly 21.

[0027] In order to facilitate the insertion of the first insertion rod 28 into the correction hole 26, a first roller 281 is rotatably mounted on one side of the first insertion rod 28 close to the square block 25. When the first insertion rod 28 is about to contact the inner wall of the guide groove, the first roller 281 contacts the inner wall of the guide groove first. Compared with the sliding friction between the first insertion rod 28 and the inner wall of the guide groove, the rolling friction between the first roller 281 and the inner wall of the guide groove makes it easier for the first insertion rod 28 to slide into the correction hole 26 along the inner wall of the guide groove.

[0028] When the heating element 4 heats the needles on the pricking plate 212, generally only the needle tips are heated, so that a conical hole or a teardrop-shaped hole can be formed in the middle layer. Therefore, when the pricking plate 212 is close to the heating element 4, the needles need to be kept perpendicular to the heating element 4. Therefore, when the pricking assembly 21 moves toward the heating element 4, correction is also required.

[0029] See also Figure 3 and Figure 4 In order to solve the above technical problems, a second plug rod 29 is fixedly installed on the inner wall of the housing 1, and the axis of the second plug rod 29 coincides with the axis of the second plug rod 29. The first plug rod 28 and the second plug rod 29 are respectively located on both sides of the square block 25. When the ratchet is located between the rack 231 and the heating element 4, the second plug rod 29 is located in the correction hole 26.

[0030] In the process of the driving member 24 driving the needling assembly 21 to move in the direction of the heating element 4, the ratchet first contacts the rack 231. When the two are in meshing state, the ratchet rotates idly and no longer drives the connecting rod 22 and the needling assembly 21 to rotate. However, due to the contact between the ratchet and the rack 231, the connecting rod 22 and the needling assembly 21 may be slightly deflected at an angle due to the action of friction. When the square block 25 contacts the second plug rod 29, the second plug rod 29 will first contact the inner wall of the guide groove 27. Under the interaction force between the guide groove 27 and the second plug rod 29, the needling assembly 21 with a deflection angle will be gradually corrected. After the needling assembly 21 is corrected, that is, the needles on the pricking plate 212 are perpendicular to the plane of the heating element 4, the second plug rod 29 can be inserted into the correction hole 26 at this time, thereby limiting the rotation of the square block 25, the connecting rod 22 and the needling assembly 21.

[0031] In order to facilitate the insertion of the second insertion rod 29 into the correction hole 26, a second roller 291 is rotatably mounted on the side of the second insertion rod 29 close to the square block 25. When the second insertion rod 29 is about to contact the inner wall of the guide groove, the second roller 291 first contacts the inner wall of the guide groove. Compared with the sliding friction between the second insertion rod 29 and the inner wall of the guide groove, the rolling friction between the second roller 291 and the inner wall of the guide groove makes it easier for the second insertion rod 29 to slide into the correction hole 26 along the inner wall of the guide groove.

[0032] In order to improve the support for the connecting rod 22, reduce the bearing pressure of the electric slider 242, and ensure the stability of the movement of the acupuncture assembly 21. A support plate is installed on the outside of the connecting rod 22, and the support plate is fixedly connected to the inner wall of the shell 1. A slide groove is opened on the support plate, and the connecting rod 22 is located in the slide groove, and the connecting rod 22 abuts against the inner wall of the slide groove.

[0033] The connecting rod 22 is supported by the support plate, thereby relieving the bearing pressure of the electric slider 242, thereby extending the service life of the electric slider. At the same time, the connecting rod 22 slides in the slide groove, thereby guiding the connecting rod 22 and improving the stability of the movement of the connecting rod 22.

[0034] The side wall of the shell 1 is provided with an inlet 5 and an outlet 6, and the outer wall of the shell 1 is provided with guide rollers 7 at the inlet 5 and the outlet 6. The sanitary napkin is guided into the shell 1 from the inlet 5 by the guide rollers 7, and goes out from the outlet 6 through the pad 3.

[0035] When the sanitary napkin passes through the pad 3, it is easy for the sanitary napkin to not contact the pad 3 and leave a gap, which will affect the puncture depth of the needle. In order to solve the above technical problems. A plurality of air guide holes 8 are provided on the pad 3, and an air pump 9 is installed on the outer shell 1. When the sanitary napkin passes through the pad 3, the air pump 9 works, and the air guide holes 8 on the pad 3 are all in a negative pressure state. When the sanitary napkin passes through the pad 3, an adsorption force will be generated on the sanitary napkin, so that the sanitary napkin is tightly attached to the pad 3. At the same time, when the needle on the pricking plate 212 is pierced on the sanitary napkin, the sanitary napkin can quickly dissipate heat to reduce excessive damage to the sanitary napkin after being heated.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
