Description

Technical Field

[0001] The utility model relates to the technical field of acupuncture machines, in particular to a high-precision synchronous double-puncture acupuncture machine. Background Art

[0002] The needle loom is used to prepare high-performance fiber fabrics by densely needle-punching multi-layer fiber cloths. The fiber web is repeatedly punctured by needles with triangular or other shaped cross-sections and barbed hooks on the edges. The fiber web from the cross-web or air-web machine is very fluffy when fed into the needle loom. It only generates a certain strength due to the cohesion between the fibers, but the strength is very poor. When multiple needles penetrate the fiber web, the barbed hooks on the needles will drive the fibers on the surface and sub-surface of the fiber web to move from the plane direction of the fiber web to the vertical direction of the fiber web, causing the fibers to shift up and down. The fibers that shift up and down will squeeze the fiber web to a certain extent, causing the fibers in the fiber web to be close together and compressed.

[0003] After searching, the existing Chinese patent publication number is: CN220413676U, which provides a high-precision synchronous needling machine. This patent improves the needling efficiency and quality by needling the fabric from the upper and lower directions respectively. The upper gear steering box of the upper spindle and the lower gear steering box of the lower spindle are connected together through the second coupling, and the upper spindle and the lower spindle are driven synchronously to improve the synchronization accuracy of the movement of the upper needle seat and the lower needle seat.

[0004] Although the above patent can synchronously drive the upper spindle and the lower spindle to improve the synchronization accuracy of the movement of the upper needle seat and the lower needle seat, the above high-precision synchronous needle loom still has the following problems: it is impossible to adjust the force between the needle and the plate, so that the pressure of the needle cannot be adjusted according to different materials and requirements.

DETAILED DESCRIPTION

[0030] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2 The utility model discloses a high-precision synchronous needle-piercing machine, comprising a base 1, a carrying plate 2 is fixedly connected to the left and right sides of the base 1, and the components that need to work can be carried by the installed carrying plate 2, a driving motor 3 is fixedly connected to the top of the carrying plate 2, and an eccentric wheel 4 is fixedly connected to the output end of the driving motor 3, and the eccentric wheel 4 is driven to rotate by the rotation of the driving motor 3, and the bottom of the eccentric wheel 4 is rotatably connected to a rotating rod 5, and the other side of the rotating rod 5 is rotatably connected to a connecting rod 6, and the bottom of the connecting rod 6 is rotatably connected to a connecting column 7, and the other side of the connecting column 7 is rotatably connected to a slider 8, and the outer ring of the slider 8 is slidably connected to an upper plate 9, and the upper plate 9 is fixedly connected to the carrying plate 2, and the sliding connection between the slider 8 and the upper plate 9 allows the needle assembly to move up and down to perform needle movement.

[0033] Reference Figure 2 and Figure 3 The bottom of the slider 8 is fixedly connected to a connecting plate 11, and the top left side of the connecting plate 11 is fixedly connected to a first push rod motor 12. The output end of the first push rod motor 12 passes through the connecting plate 11 and is fixedly connected to a nylon rope 13. The contraction of the first push rod motor 12 causes the needle plate 16 to contract through the nylon rope 13, thereby deforming the spring 15. The bottom of the nylon rope 13 is fixedly connected to the needle plate 16. Fixedly connected telescopic columns 14 are evenly distributed on the bottom of the connecting plate 11. The installed telescopic columns 14 can fix the spring 15 and contract at the same time. The outer ring of the telescopic column 14 is slidably connected to the spring 15, and a moving component is provided on the top of the base 1.

[0034] Reference Figure 1-3The moving component includes a lower plate 17, which is slidably connected to the carrying plate 2. The installation of the lower plate 17 allows the needle plate 16 to move so as to intersect with the needle plate 16 below the upper plate 9, thereby improving the processing accuracy. The front and rear sides of the lower plate 17 are fixedly connected to the limiting plate 10, and the lower plate 17 is allowed to slide safely on the carrying plate 2 through the limiting of the limiting plate 10. A second push rod motor 18 is fixedly connected to one side of the base 1, and a connecting block 19 is fixedly connected to the output end of the second push rod motor 18, and the connecting block 19 is slidably connected to the base 1. The second push rod motor 18 allows the connecting block 19 to slide on the base 1, thereby driving the lower plate 17 to slide. The other side of the connecting block 19 is fixedly connected to the driving motor 3, and the lower plate 17 is slidably connected to the slider 8.

[0035] Working principle: when it is necessary to process materials, the driving motor 3 is started at the same time to drive the eccentric wheel 4 to rotate so that the slider 8 and the upper plate 9 slide up and down so that the needle plate 16 moves together. When it is found that the pressure of the needle needs to be adjusted during processing, the first push rod motor 12 is started to shrink the nylon rope 13, so that the needle plate 16 shrinks and compresses the spring 15 on the telescopic column 14, so as to provide greater flexibility and adaptability to meet the needs of different needle applications. After starting the driving motor 3 for a period of time, the second push rod motor 18 is started to slide the connecting block 19 on the base 1, thereby driving the lower plate 17 to slide on the supporting plate 2, thereby forming a situation where the needles between the needle plates 16 cross each other, thereby greatly improving the processing accuracy. At the same time, the limit plate 10 on the lower plate 17 can well ensure that the lower plate 17 slides safely on the supporting plate 2.
