DETAILED DESCRIPTION

[0022] The implementation modes of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation modes of the present invention are not limited to the following embodiments, and the present invention relates to relevant necessary components in the technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the technical personnel in the technical field.

[0023] A non-speed-reducing embossing and perforating device for producing sanitary products, comprising a device body, an unwinding device 1, a conveying frame 2, an embossing and perforating device 3, a slitting device 4 and a winding device 5 arranged in sequence along the length direction of the device body; In the technical solution of the unwinding device 1 of the present invention, the unwinding device 1 includes a first unwinding group 11 and a second unwinding group 12, and a heating wire material receiving group 8 is provided at the material output end of the first unwinding group 11 and the second unwinding group 12, and a material storage group 9 connected to the heating wire material receiving group 8 is provided on the conveying frame 2. After the material passes through the first unwinding group 11 or the second unwinding group 12, it is unwound into the material storage group 9 and stored through multiple Z-shaped windings; The first unwinding group 11 includes an unwinding bracket 13, an unwinding roller 14, a supporting bracket 15 and a first linear drive mechanism 16, the unwinding roller 14 extends in a direction perpendicular to the end face of the unwinding bracket 13, one end of the supporting bracket 15 is hinged to the unwinding bracket 13, and the other end is hinged to the output end of the first linear drive mechanism 16, the bottom end of the first linear drive mechanism 16 is hinged to the unwinding bracket 13, and the first linear drive mechanism 16 drives the supporting bracket 15 to swing back and forth toward the unwinding roller 14; During unwinding, the material roll is passed through the unwinding roller 14, and the supporting bracket 15 is supported at the bottom of the material roll under the drive of the first linear drive mechanism 16. As the material roll is unwound, the diameter of the material roll is reduced, and the output end of the first linear drive mechanism 16 continues to extend to keep the supporting bracket 15 in contact with the bottom of the material roll.

[0024] It should be noted that the second unwinding group 12 has the same structure as the first unwinding group 11, and the first unwinding group 11 and the second unwinding group 12 are symmetrically arranged with the heating wire material receiving group 8 as the center line. When the first unwinding group 11 unwinds the material, the material head of the second unwinding group is pulled into the heating wire material receiving group 8 by manual or mechanical traction to prepare the material receiving equipment.

[0025] In the technical solution of the heating wire splicing group 8 of the present invention, the heating wire splicing group 8 includes a first welding component 81, a second welding component 82 and a welding plate 83; The first welding assembly 81 includes a welding block 84, a horizontally arranged first reciprocating drive mechanism 85, and a welding wire arranged on the end surface of the welding block 84 facing the welding plate 83, the welding block 84 is connected to the output end of the first reciprocating drive mechanism 85, and the first reciprocating drive mechanism 85 drives the welding block 84 to reciprocate toward the welding plate 83; The second welding assembly 82 has the same structure as the first welding assembly 81 , and the first welding assembly 81 and the second welding assembly 82 are symmetrically arranged with the welding plate 83 as the center line.

[0026] It should be noted that the output ends of the first welding assembly 81 and the second welding assembly 82 are arranged horizontally opposite to each other, and the welding plate 83 is vertically arranged between the first welding assembly 81 and the second welding assembly 82. When the first unwinding group 11 is continuously unwinding, the material head of the second unwinding group 12 passes from the second welding assembly 82 and the welding plate 83 from bottom to top by manual or mechanical traction, and is folded along the top of the welding plate 83 to between the first welding assembly 81 and the welding plate 83; When the first unwinding group 11 completes unwinding and starts to connect the materials, the first reciprocating drive mechanism 85 drives the welding block 84 to move horizontally toward the welding plate 83, and utilizes the welding wire to weld the cloth unwound by the first unwinding group 11 with the material heads unwound by the second unwinding group 12, and cuts off the excess material tails of the first unwinding group 11, so as to achieve the goal of eliminating tail materials and keeping the material heads available without shaving waste.

[0027] In the technical solution of the material storage group 9 of the present invention, the material storage group 9 includes a first swing bracket 91, a second swing bracket 92 and a material storage roller 93, and the ends of the first swing bracket 91 and the second swing bracket 92 are provided with a circumferential driving mechanism 94 for driving the first swing bracket 91 and the second swing bracket 92 to swing toward each other or back to back, and the material storage roller 93 is arranged at equal intervals along the length direction of the first swing bracket 91 and the second swing bracket 92; The conveying frame 2 is provided with a material storage plate frame 21 at a position corresponding to the material storage group 9, and the first swing bracket 91 and the second swing bracket 92 are vertically and parallelly arranged on the end surface of the material storage plate frame 21; There are two circumferential drive mechanisms 94, which are hinged to the bottom end of the first swing bracket 91 and the top end of the second swing bracket 92 respectively. The storage rollers 93 on the first swing bracket 91 and the storage rollers 93 on the second swing bracket 92 are staggered in the horizontal direction to form a Z-shaped storage conveying path.

[0028] It should be noted that the material unwound by the unwinding device 1 is transported from bottom to top to the storage group 9, and the storage group 9 is provided with a plurality of storage rollers 93 on the first swing bracket 91 and the second swing bracket 92. The material is wound on the storage rollers 93 of the first swing bracket 91 and the second swing bracket 92, and serves to store the material while being transported. When the first unwinding group 11 and the second unwinding group 12 are changing materials and receiving materials, the circumferential driving mechanism 94 drives the first swing bracket 91 to swing toward the second swing bracket 92, and the circumferential driving mechanism 94 drives the second swing bracket 92 to rotate. The bracket 92 swings toward the first swing bracket 91, thereby shortening the gap of the material storage conveying path between the first swing bracket 91 and the second swing bracket 92, so that the material storage group 9 is close to being closed. When the unwinding device 1 changes materials and connects materials, the materials in the material storage group 9 are continuously output to the lower workstation, thereby realizing non-stop material change and connection. When the material connection action is completed, it switches to the second unwinding group 12 for unwinding. At the same time, the material storage group 9 starts to store materials to the initial position to prepare for the next material connection. The above actions are repeated to achieve the purpose of connecting the materials on the first unwinding group 11 and the second unwinding group 12 without reducing the speed.

[0029] In the technical solution of the slitting device 4 of the present invention, a slitting roller 41, a first active roller 42 and a second active roller 43 arranged in a herringbone shape are provided at the output end of the slitting device 4, the slitting roller 41 abuts against the output end of the slitting device 4, the first active roller 42 and the second active roller 43 are symmetrically arranged on both sides of the slitting roller 41 and abut against the outer surface of the slitting roller 41; It should be noted that after the material is processed by the embossing and punching device 3, it bypasses from the bottom of the first active roller 42, passes through the abutment between the first active roller 42 and the slitting roller 41, bypasses along the top of the slitting roller 41, and passes downward through the abutment between the second active roller 43 and the slitting roller 41, and is output toward the winding device 5 to complete the winding. The material is wrapped in a herringbone shape between the three rollers, which cuts off the tension of the material before and after slitting, ensuring that the material tension is always consistent during slitting and the width is stable.

[0030] In the technical solution of the deviation correction device 22 of the present invention, the conveying frame 2 is provided with a deviation correction device 22, and the deviation correction device 22 includes a detection device 23 arranged above the storage group 9 and a deviation correction roller arranged at the conveying frame 2 near the discharge end; The detection end of the detection device 23 is provided with a detection roller, and the rear end of the detection device 23 is provided with a linear telescopic cylinder that drives it to move horizontally toward the detection roller; The conveyor frame 2 is provided with two correcting rollers at a position near the discharge end, and the ends of the correcting rollers are provided with T-shaped brackets and a swing device for driving the correcting rollers to swing horizontally. When the material is conveyed to the detection roller through the material storage group 9, the detection device 23 detects the width and edge position of the material, and corrects the position of the material through the deviation correction device 22 at the rear end of the conveying frame 2. Specifically, the deviation correction roller is driven to tilt toward the material correction direction through the swing device, so that the material is gradually corrected during the conveying process; The detection device 23 involved in the present invention can actually be set up using the detection device 23 in the existing non-woven fabric conveying equipment, such as infrared detection correction and visual image detection correction. The detection device 23 is selected to be able to obtain and meet the detection functions required by the present invention. Generally speaking, most types of detection devices 23 can meet this point, so their structure and basic control principles will not be explained in detail here.

[0031] Furthermore, in the above scheme, the embossing and perforating device 3 includes a circular bracket 31 and a convex embossing roller 32 and a concave embossing roller 33 inserted into the circular bracket 31 , and the convex embossing roller 32 is arranged above the concave embossing roller 33 .

[0032] Furthermore, in the above scheme, a tensioning mechanism 10 is provided between the slitting device 4 and the embossing and punching device 3, and the tensioning mechanism 10 includes a tensioning bracket 101, tensioning rollers 102 provided at both ends of the tensioning bracket 101, and a second linear driving mechanism 103; The middle part of the tensioning bracket 101 has a hinge axis 104 perpendicular to the material conveying direction. The second linear drive mechanism 103 is horizontally arranged on one side of the tensioning bracket 101, and the output end is hinged to one end of the tensioning bracket 101, so the fixed end of the second linear drive mechanism 103 is hinged to the equipment body.

[0033] In the technical solution of the winding device 5 of the present invention, the winding device 5 includes an air shaft 51, a friction roller 52, a material support assembly 53, a material pressing device 6 and a flat pressing device 7, the material support assembly 53 has the degree of freedom to rotate about the axis of the friction roller 52, and the material pressing device 6 has the degree of freedom to rotate about the axis of the friction roller 52; A hook portion 61 and a second reciprocating driving mechanism 62 for driving the hook portion 61 to move linearly and reciprocally are provided at the end of the pressing device 6 , and the inflatable shaft 51 is provided on the inner side of the hook portion 61 .

[0034] As an improvement of the above solution, the material supporting assembly 53 includes a material supporting bracket 531 and a material supporting aluminum roller 532 and a serrated knife 533 horizontally arranged on the material supporting bracket 531; The flat pressing device 7 comprises a guide rail 71 horizontally arranged at the unloading end of the unwinding device 1 and a flat pressing block 72 arranged on the guide rail 71 and sliding back and forth along the length direction of the guide rail 71 .

[0035] When the winding device 5 is changing the roll, the inflatable shaft 51 with double-sided tape pre-affixed is placed on the inner side of the hook portion 61 on the pressing device 6, the supporting component 53 rotates counterclockwise from the bottom to the top of the friction roller 52, and the tail of the wound material is lifted up by the supporting aluminum roller 532, and the material is quickly broken by the serrated knife 533. The broken material is adhered to the inflatable shaft 51 for winding, and after the supporting component 53 rotates counterclockwise to the initial position at the bottom, the pressing device 6 rotates the inflatable shaft 51 counterclockwise to a horizontal position, and after the flat pressure block 72 moves toward the pressing device 6 and presses the inflatable shaft 51 onto the friction roller 52, the inflatable shaft 51 is separated from the hook portion 61, and the pressing device 6 rotates clockwise to the initial position, waiting for the next material connection.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
