Description

Round table type felt sleeve needling machine

Technical Field

The utility model belongs to the technical field of special processing machinery for nonwoven felts, and particularly relates to a circular truncated cone-shaped felt sleeve needling machine.

Background

The above-mentioned circular truncated cone-shaped felt cover is known as a shape of a hollow, i.e., vertically penetrating, sleeve, as seen in daily life, in which the opening diameter of one end is small and the opening diameter of the other end is large, as the definition of the circular truncated cone-shaped felt cover is interpreted by the term. The raw material of the round table-shaped felt sleeve mainly adopts carbon fiber with excellent heat preservation and heat insulation performance, and the round table-shaped felt sleeve can be used as a protective sleeve for heat preservation, heat insulation, shock resistance, buffer enhancement and the like of valuable industrial products, and can be applied to the fields of military industry and aerospace, for example, as a specific safety protective sleeve for certain military products.

For conventional needling machines, needling machines for processing nonwoven products such as nonwoven fabrics, nonwoven mats, etc., are naturally conceivable, and such needling machines are not known in the published chinese patent literature, such as CN101149286B (automated multifunctional needling machine), CN102808290B (roller needling machine), CN106087258B (double-sided-to-needling machine), CN105734836a (a low noise needling machine), CN106087259a (a high speed biaxial-oriented ectopic-to-needling machine), and CN106988023a (a small blanket-to-blanket needling machine), etc. In addition, needling machines for carbon fiber nonwoven products are also known in the patent literature, such as CN211036324U (a needling machine for processing carbon fiber products), CN211171122U (carbon fiber flat needling machine), CN212771285U (a needling machine for carbon fibers) and CN103161033B (a needling machine for processing carbon fiber products), and the like.

The needling machine exemplified above is not limited to only one part of the production line of a nonwoven product set including a bale opener, an opener, a lapping machine and a needling machine, and the baled nonwoven fiber bale is opened by the bale opener and fed to the opener by a conveyor curtain, is lapped by the opener after being opened, is lapped by the lapping machine into a web layer of desired grammage or thickness, is needled by the needling machine, and is discharged to obtain a nonwoven product such as a nonwoven fabric, nonwoven felt or other similar planar and unlimited length product. However, the round table-shaped felt cover cannot be produced by adopting the traditional complete non-woven product production line because of the special shape, and even cannot be used even by a traditional needling machine. Because the trapezoidal felt is needled by the special-shaped felt needling machine, and then two sides of the trapezoidal felt in the length direction are jointed by a machine such as an industrial sewing device or by hand to form the round table-shaped felt sleeve embryonic form, the entanglement effect (entanglement effect formed in the needling process) among fibers such as carbon fibers forming the round table-shaped felt sleeve embryonic form cannot reach the firm degree required by practical use, and the round table-shaped felt sleeve embryonic form is manufactured by the process and then needled for the second time so as to achieve the aim of full compaction.

It is limited by the foregoing factors, and the current densification, i.e. solidification, processing mode for the round table-shaped felt sleeve blank is generally as follows: the round table shaped felt cover embryonic form processed by the previous working procedure is arranged on the felt cover die, and the needling and the round table shaped felt cover embryonic form are continuously and manually needled by a worker, so that the round table shaped felt cover embryonic form is firm (i.e. compact) until the round table shaped felt cover embryonic form is formed into the round table shaped felt cover which finally meets the use requirement.

Undoubtedly, the efficiency of needlepunching machines capable of achieving densification needling of round-table-shaped mat blanks without needlepunching by hand is quite low due to the lack of a relatively reasonable and simple structure at present, and not only is the quality of needling insufficient to meet the desired requirements, but also the quality difference of round-table-shaped mats made by the same worker cannot be eliminated, and moreover, the working intensity and psychological pressure of workers are high.

The invention patent application publication number CN110373813A discloses a cylinder needling machine and a manufacturing method of a seamless belt base cloth cylinder felt, and the publication number CN106988023B discloses a small-diameter felt sleeve needling machine which can only process cylindrical felts with the same diameter and cannot process the strengthening of a round table-shaped felt sleeve.

In view of the above, it is of positive importance to design a needling machine that meets the requirements for needling a round-table-shaped felt jacket, with the technical solutions described below being produced in this context.
