DETAILED DESCRIPTION

[0026] 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 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.

[0027] like Figure 1-Figure 5The piercing processing device of an elastic composite paper shown in the figure comprises a feed conveyor roller 1, a discharge conveyor roller 2 and a piercing roller 4. The elastic composite paper tape is input from the feed conveyor roller 1 and is driven toward the discharge conveyor roller 2 to form a tape drive route 3. The piercing roller 4 is installed at a position between the feed conveyor roller 1 and the discharge conveyor roller 2. The piercing roller 4 is arranged on the tape drive route 3. The piercing roller 4 is connected to the discharge conveyor roller 2 to form a synchronous and same-speed rotation effect. The elastic composite paper tape passes through the roller surface of the piercing roller 4. The elastic composite paper tape and the roller surface of the piercing roller 4 form a section of adhesion. The puncture roller 4 has a closing stroke 31, and a plurality of pricking needles 5 are movably mounted on the roller surface of the puncture roller 4. The pricking needles 5 can extend beyond the roller surface of the puncture roller 4. The pricking needles 5 puncture the elastic composite paper tape within the fitting stroke 31. The present invention relies on the feed conveyor roller 1 and the discharge conveyor roller 2 to transmit the elastic composite paper tape. The puncture roller 4 can automatically puncture the paper surface during the transmission of the elastic composite paper tape. Due to the increase in puncture holes, the air permeability of the elastic composite paper is significantly enhanced, which can meet the application requirements in the direction of sanitary products. The puncture operation of the present invention has the advantages of high degree of automation and controllable puncture points.

[0028] like Figure 2 and Figure 3 As shown, the roller surface of the puncturing roller 4 is equipped with a plurality of needle boxes 6, each needle box 6 is correspondingly equipped with a puncture needle 5, the needle boxes 6 are evenly arranged, and the puncture needles 5 can form a uniform puncture effect on the paper surface. The interior of the puncturing roller 4 is hollow, and the tail ends of the puncture needles 5 extend into the interior of the puncturing roller 4 after passing through the needle boxes 6. The puncturing roller 4 is equipped with a needle driving mechanism 7, which is used to drive the extension and retraction of the puncture needles 5. The needle driving mechanism 7 includes a needle driving seat 71 fixedly inserted in the puncturing roller 4, and the puncture needles 5 are arranged on the roller surface of the puncturing roller 4. The tail end of the needle is kept in contact with the outer wall of the needle drive seat 71, and a protrusion 711 is connected to the outer wall of the needle drive seat 71. When the tail end of the needle of the pricking needle 5 is not in contact with the protrusion 711, the needle head of the pricking needle 5 is hidden in the needle box 6, which neither affects the transmission of the paper tape nor effectively protects the pricking needle 5. When the tail end of the needle of the pricking needle 5 is in contact with the protrusion 711, the needle head of the pricking needle 5 extends outward beyond the roller surface of the puncture roller 4. At this time, the pricking needle 5 can form a puncture effect on the tape surface of the elastic composite paper tape.

[0029] like Figure 4 As shown, the raised portion 711 is arranged corresponding to the fitting stroke 31, and the raised portion 711 corresponds to the state that the needle head of the pricking needle 5 extends beyond the roller surface of the puncture roller 4. During the length stroke of the raised portion 711, the pricking needle 5 will continue to be inserted into the tape surface of the paper tape until the length of the raised portion 711 is completed and the pricking needle 5 leaves the tape surface of the paper tape. The state that the needle head of the pricking needle 5 extends beyond the roller surface of the puncture roller 4 only appears in the fitting stroke 31. Before completing the fitting stroke 31, the pricking needle 5 needs to automatically retract and leave the paper tape, which will neither affect the transmission of the paper tape nor cause the pricking needle 5 to be pulled, bent or damaged.

[0030] like Figure 3 As shown, the puncture needle 5 and the needle box 6 are elastically installed to ensure that the puncture needle 5 can automatically retract. A spring hole 61 is provided in the needle box 6, and a spring 62 and a piston 63 are installed in the spring hole 61. The piston 63 is fixedly connected to the outer wall of the puncture needle 5, and the piston 63 is matched and installed in the spring hole 61. The piston 63 plays a role in guiding the movement of the puncture needle 5. The piston 63 can drive the puncture needle 5 to move in the length direction of the spring hole 61 (that is, telescopic movement). The puncture needle 5 is installed through the needle box 6, and the needle head of the puncture needle 5 can move beyond the roller surface of the puncture roller 4. The needle tail of the puncture needle 5 can extend to contact the outer wall of the needle drive seat 71. When the needle tail of the puncture needle 5 does not contact the protrusion 711, the puncture needle 5 is only pushed by the elastic force of the spring 62. At this time, the spring 62 can pull the puncture needle 5 to move toward the central axis direction of the puncture roller 4, and the needle head of the puncture needle 5 can be hidden in the needle box 6.

[0031] like Figure 2 As shown, one end of the puncture roller 4 is open and the other end is closed, and the first roller frame 42 and the second roller frame 43 are respectively installed at both ends of the puncture roller 4, the closed end of the puncture roller 4 is connected to the shaft head 41, the shaft head 41 is rotatably connected to the first roller frame 42, the open end of the puncture roller 4 is rotatably connected to the second roller frame 43, the needle drive seat 71 is installed from the open end of the puncture roller 4, the first roller frame 42 and the second roller frame 43 play the role of rotating installation of the puncture roller 4, during production, the puncture roller 4 can rotate at a uniform speed, with the rotation of the puncture roller 4, the puncture needle 5 passes through the raised portion 711 of the needle drive seat 71 from time to time, the puncture needle 5 extends out of the roller surface of the puncture roller 4, and forms a puncture effect on the surface of the paper tape that has passed the fitting stroke 31.

[0032] like Figure 3 As shown, the outer wall of the needle box 6 is provided with a thread, and the needle box 6 is threadedly installed on the puncture roller 4. Two symmetrical power-assisting holes 64 are opened on the top of the needle box 6. The needle box 6 is detachably installed (in order to facilitate the replacement of different needle shapes). The power-assisting holes 64 are used to insert the mounting rod to facilitate the twisting of the needle box 6. The top of the needle box 6 does not exceed the roller surface of the puncture roller 4. The top of the needle box 6 is flat with the roller surface of the puncture roller 4 or slightly lower than the roller surface of the puncture roller 4 so as not to affect the transmission of the paper tape.

[0033] like Figure 2As shown, the needle-driving mechanism 7 also includes an outer bracket 72 and a transverse axis 73. The transverse axis 73 is fixedly connected to the top of the outer bracket 72. The needle-driving seat 71 is fixedly connected to the transverse axis 73. An axle support seat 44 is installed in the puncture roller 4. One end of the transverse axis 73 is rotatably connected to the axle support seat 44. The axle support seat 44 supports one end of the transverse axis 73. Since it is a rotatable connection, it does not affect the rotation of the puncture roller 4. In the present invention, the second roller frame 43 and the puncture roller 4 are both open on one side to facilitate the installation of the needle-driving seat 71. The needle-driving seat 71 is fixedly installed, and the puncture roller 4 is rotatably installed. Therefore, with the transmission of the elastic composite paper tape, the needle 5 can move to contact the raised portion 711 on the needle-driving seat 71 each time, and can form a puncture effect on the paper tape that is attached to the transmission of the puncture roller 4.

[0034] like Figure 1 As shown, a first transmission pulley 21 is installed on the discharge conveyor roller 2, and a second transmission pulley 411 is installed on the shaft head 41 of the puncture roller 4. The first transmission pulley 21 and the second transmission pulley 411 are connected through belt transmission. The discharge conveyor roller 2 is connected to a motor, which is the main power of the paper tape transmission. Through the above design, the puncture roller 4 and the discharge conveyor roller 2 can rotate synchronously at the same speed, so that the needle 5 can only form a puncture effect on the paper tape without forming a large rupture.

[0035] It is found in actual production that high-quality puncture holes cannot be formed by acupuncture alone, which will affect the improvement of air permeability. Therefore, the present invention adopts an electrically heated structure design for the raised portion 711 of the needle drive seat 71. During production, the raised portion 711 can be electrically heated. The needle 5 is made of a heat-conducting material and can conduct heat well. A heating effect can be formed when the needle 5 contacts the raised portion 711. At this time, the needle 5 has heat, that is, the needle 5 for puncture is in a heated state. Under the length stroke of the raised portion 711, the needle 5 and the paper tape maintain a puncture state. Since the needle 5 has heat, it can form a heat-setting effect on the puncture hole formed by the puncture, ensuring high-quality forming of the puncture hole. Under this design, high-quality and uniform puncture holes can be formed on the paper tape.

[0036] A puncture processing method for elastic composite paper is implemented by using an elastic composite paper puncture processing device and includes the following steps:

[0037] (a) The discharging conveyor roller 2 and the puncturing roller 4 are connected by belts, and the elastic composite paper tape passes through the feeding conveyor roller 1, the puncturing roller 4 and the discharging conveyor roller 2 in sequence to form a tape transmission route 3. The elastic composite paper tape forms a laminating stroke 31 on the roller surface of the puncturing roller 4. In the laminating stroke 31, the tape surface of the paper tape maintains laminating contact with the roller surface of the puncturing roller 4;

[0038] (b) Power is turned on to start the electric heating function of the raised portion 711, and all the needles 5 in contact with the raised portion 711 are in a heated state, that is, the needles 5 within the laminating stroke 31 are in a heated state, and the needles 5 extend beyond the roller surface of the puncturing roller 4, and the needles 5 form a puncture effect on the paper tape, and the puncture holes are shaped by heat;

[0039] (c) Turn on the discharging conveying roller 2, so that the discharging conveying roller 2 and the piercing roller 4 rotate synchronously at the same speed, and the elastic composite paper tape is pulled to form a transmission effect. As the piercing roller 4 rotates, the roller surface and the paper tape pass through the raised portion 711 area at the same time, and the puncture needles 5 on the roller surface are affected by the raised portion 711 to form an effect of extending and piercing the paper tape. This piercing effect only appears in the 31st section of the laminating stroke. As the paper tape continues to be driven, puncture holes are continuously formed on the surface of the paper tape, and the puncture holes can significantly enhance the air permeability of the elastic composite paper.

[0040] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
