DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, 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 them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] like Figure 1-2 As shown, the fiber flannel hot cutting device in one embodiment of the utility model comprises a lower mold mechanism 10 and an upper mold mechanism 20 arranged relatively, the lower mold mechanism 10 comprises a lower mold plate 11 for carrying the fiber flannel. The upper mold mechanism 20 comprises an upper mold plate 21, a punching blade 22 and a top blade 23, the upper mold plate 21 can approach or move away from the lower mold plate 11 under an external driving device, the punching blade 22 is fixed on the upper mold plate 21 and faces the lower mold plate 11, and can approach the lower mold plate 11 with the movement of the upper mold plate 21, and cut the fiber flannel on the lower mold plate.

[0025] The punching blade 22 may be bent or deviated after long-term use, resulting in an increase in the defect rate. Therefore, in this embodiment, a top blade 23 is fixed on the upper template 21, and the top blade 23 supports the punching blade 22 to maintain its shape during long-term use, prevent it from being bent or deviated, and ensure the yield rate.

[0026] In this embodiment, the top blade 23 includes a base 231 fixed to the upper mold plate 21 , and a top block 232 protruding from the base 231 . The top block 232 directly abuts against the punching blade 22 to maintain its shape.

[0027] In this embodiment, the punching blade 22 includes two first blades 221 arranged opposite to each other. To ensure that each blade operates stably for a long time, each first blade 221 abuts against a top blade 23 .

[0028] Preferably, since the first blade 221 is relatively long, a plurality of top blade members 23 are respectively arranged on the side of each first blade 221 to increase the number of supporting positions and ensure the rigidity and stability of the first blade 221. Figure 1As shown, the top blade members 23 on the outer side of the first blade 221 have the same distance between each other.

[0029] like Figure 1 As shown, the punching blade 22 also includes two second blades 222 arranged opposite to each other, which are respectively connected to the ends of the first blade 221, so that the entire punching blade 22 is in the shape of a "mouth". A top blade 23 is also arranged on the outside of the second blade 222 to support and provide support for the second blade 222 to prevent bending or displacement. All top blades 23 are arranged on the outside of the first blade 221 or the second blade 222, and because of their short length, they are Figure 1 In the illustrated embodiment, only one top blade 23 is disposed on the outer side of each second blade 222 .

[0030] It is easy to imagine that the number and position of the top blades 23 on the outside of the first blade 221 and the second blade 222 are not limited by the above embodiment and can be set and adjusted according to actual production conditions and support effects to achieve the best effect.

[0031] Preferably, in order to ensure the moving direction and the cutting position of the punching blade 22, a positioning mechanism is provided between the upper and lower molds, including a positioning column 25 protruding from the upper mold 21, and a positioning hole 12 recessed on the lower mold 11 and cooperating with the positioning column 25. The positioning column 25 can be inserted into the positioning hole 12, so that the punching blade can always maintain the same position when it moves downward to the lower mold 11.

[0032] Furthermore, the upper template 21 and the lower template 11 are both rectangular structures. Therefore, in order to improve the positioning effect, positioning columns 25 are distributed at the four corners of the upper template 21, and corresponding positioning holes 12 are respectively provided at the four corners of the lower template 11 to further ensure the moving direction of the punching blade 22.

[0033] It is conceivable that the number and positions of the positioning columns 25 and the positioning holes 12 are not limited by the above-mentioned embodiments, that is, the positioning columns 25 can be set on the lower template 11 and the positioning holes 12 can be set on the upper template 21, or the positioning columns 25 and the positioning holes 12 can be set on the lower template 11 at the same time, and the upper template 21 can be adaptively set.

[0034] In one embodiment, the upper mold mechanism 20 further includes a heating assembly 24 for heating the punching blade 22, and the heating assembly 24 includes a heating platform 241 and a heating pipe 242. The heating pipe 242 is fixed to the heating platform 241 and heats it, and the upper mold plate 21 is also fixed to the heating platform 241. Since the heating pipe 242 needs to heat the heating platform 241 first, and then the heating platform 241 heats the upper mold plate 21 and the punching blade 22, the two heating operations can well ensure the consistency of temperature and prevent the punching blade 22 from having a temperature difference that affects the normal cutting operation.

[0035] like Figure 1 As shown, the heating pipe 242 is arranged at the edge of the heating platform 241, and the heating pipe 242 is arranged on both opposite sides of the heating platform 241 to improve the heating effect and further ensure the temperature consistency. It is easy to imagine that the heating pipe 242 can also be arranged on the remaining two sides of the heating platform 241. The heating component 24 can be heated by liquid heating, electric heating or other forms, which are not limited in this embodiment.

[0036] In one embodiment, the temperature of the punching blade 22 is controlled at 95° by adjusting the heating pipe 242 . When the fiber flannel is cut at this temperature, the defect rate is reduced by 8%, so the yield is higher and the production cost is reduced.

[0037] It is conceivable that the specific temperature of the punching blade 22 can be adjusted according to the different proportions of different materials to achieve the optimal set temperature and minimize the defective rate.

[0038] In a preferred embodiment, the lower template 11 is polished to have a smooth bearing surface, maximizing the smoothness of its surface to ensure that the punching blade 22 is not damaged after pressing down, and is also conducive to the storage of the fiber flannel.

[0039] The fiber flannel hot cutting equipment in this embodiment can work stably for a long time and can smoothly cut through the edge fibers of the fiber flannel. On this basis, the punching speed can be increased. Before optimization, the punching rate is 120 PCS / H. After optimization, the punching rate can be stabilized to 410 PCS / H without damaging the punching blade 22, thereby greatly improving production efficiency.

[0040] It is obvious 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 regarded as exemplary and non-restrictive from any point of view, 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. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
