Description

Technical Field

[0001] The invention belongs to the technical field of special-shaped non-woven product processing machinery, and in particular relates to a lifting and rotating device for a felt mold bearing platform. Background Art

[0002] The special-shaped non-woven products mentioned above mainly refer to non-woven felts with irregular side lengths and certain special uses. A typical example is a non-woven felt with a trapezoidal plane shape obtained after needling, and then sewn by another subsequent sewing process after needling to form a hollow cone-shaped non-woven felt cone sleeve. This product can be used as a heat insulation and heat protection sleeve for the head of missiles, shells, etc. in the aerospace military field. The essential difference from the processing of conventional non-woven fabrics is that in order to obtain the aforementioned trapezoidal non-woven felt, it is usually necessary to equip the corresponding felt mold, otherwise it will cause serious waste, because if according to the conventional production mode of non-woven products, after needling by a needle punching machine, the needle punched product can be cut into the trapezoidal shape that meets the size requirements, but if processed in this way, there is no doubt that it will cause waste of resources due to the large cutting margin. Moreover, the material of this non-woven felt is very expensive, and the loss caused by cutting is usually unbearable for ordinary non-woven product manufacturers.

[0003] After searching by the applicant, a large amount of technical information related to acupuncture machines can be found in the disclosed Chinese patent documents, such as: CN101149286B (automatic multifunctional acupuncture machine), CN102808290B (drum acupuncture machine), CN106087258B (double-sided acupuncture machine), CN105734836A (a low-noise acupuncture machine), CN106087259A (a high-speed double-axis guided acupuncture machine) and CN106988023A (a small blanket cover acupuncture machine), etc. In addition, needle punching machines for carbon fiber nonwoven products can also be found in patent documents, such as CN211036324U (a needle punching machine for processing carbon fiber products), CN211171122U (a flat needle punching machine for carbon fiber), CN212771285U (a needle punching machine for carbon fiber) and CN103161033B (a needle punching machine for processing carbon fiber products), etc. However, there is no technical inspiration for processing the final product or the final shape of the nonwoven shaped felt which is a hollow cone and can be used as a heat-proof cone sleeve for the head of a missile. The applicant's persistent exploration and repeated design show that the use of a felt mold that meets the requirements of needle punching shaped nonwoven felt is an ideal choice to avoid waste, but the felt mold needs to provide needle punching conditions for the needle plate (with needles arranged on the needle plate) of the needle punching mechanism of the structural system of the needle punching machine. Because the felt mold of the aforementioned special-shaped non-woven felt has a large head end and a small head end, that is, a large radius end and a small radius end, and during the needling process of the needles on the needle supply plate, the felt mold together with the composite fiber layer to be needling covered thereon needs to be in a horizontal state, and the felt mold must also rotate slowly during the needling process. If the above two technical factors are not reasonably solved, it will be difficult or even impossible to process the aforementioned special-shaped non-woven felt products such as trapezoidal shapes. The technical solution to be introduced below is produced under this background. Summary of the invention

[0020] In order to more clearly understand the technical essence and beneficial effects of the present invention, the applicant provides a detailed description in the form of embodiments below. However, the description of the embodiments is not a limitation of the present invention. Any equivalent changes made based on the concept of the present invention that are merely formal and not substantial should be regarded as within the scope of the technical solution of the present invention.

[0021] In the following description, all concepts related to up, down, left, right, front and back directions or orientations are based on Figure 1 The position state is taken as a reference, and thus it cannot be understood as a special limitation on the technical solution provided by the present invention.

[0022] See also Figures 1 to 3, shows a shaped felt mold carrier 10, a shaped felt mold carrier platform 20, a shaped felt mold carrier platform bracket 30, a shaped felt mold carrier platform turntable drive mechanism 4, a shaped felt mold carrier platform bracket lifting and restoring mechanism 5 and a moving trolley 6, the shaped felt mold carrier 10 is fixed on the shaped felt mold carrier platform 20, and the shaped felt mold carrier platform 20 is arranged on the shaped felt mold carrier platform bracket 30, the rear end of the shaped felt mold carrier platform bracket 30 is pivotally connected to the rear end of the moving trolley 6, and the front end of the shaped felt mold carrier platform bracket 30 is connected to the shaped felt mold carrier platform bracket lifting and restoring mechanism 5, and the shaped felt mold carrier platform bracket lifting and restoring mechanism 5 is arranged on the aforementioned shaped felt mold carrier platform bracket 3 0 and is also connected to the front end of the aforementioned moving trolley 6, the shaped felt mold bearing platform bracket lifting and restoring mechanism 5 makes the shaped felt mold bearing platform bracket 30 and the front side of the shaped felt mold bearing platform 20 lift upward so that the aforementioned shaped felt mold bearing frame 10 is in a horizontal state during the needling process, the shaped felt mold bearing platform turntable driving mechanism 4 is arranged at the rear end of the aforementioned shaped felt mold bearing platform bracket 30 and is transmission connected with the shaped felt mold bearing platform 20, the shaped felt mold bearing platform turntable driving mechanism 4 drives the shaped felt mold bearing platform 20 and rotates together with the aforementioned shaped felt mold bearing frame 10, the moving trolley 6 is arranged on a pair of moving trolley guide rails 61 for forward and backward movement, and the pair of moving trolley guide rails 61 are laid on the floor.

[0023] Based on the above, and combined with Figures 1 to 3 It can be seen from the diagram that the front side of the shaped felt mold supporting platform 20 together with the front side of the shaped felt mold supporting frame 10 is tilted downward relative to the rear side, that is, the front side is significantly lower than the rear side. In this state, the needling machine corresponding to the top of the shaped felt mold supporting frame 10 cannot perform needling, because only when the needles on the needle plate of the needling mechanism of the structural system of the needling machine fully correspond to the object to be pierced can the needling requirements be met. In other words, since the aforementioned needle plate together with the needles arranged thereon are on a horizontal plane as a whole, the object to be pierced must also remain horizontal relative to the needle plate and the needle areas thereon, that is, the object to be pierced must remain parallel to the needles in the area corresponding to the needles.
