Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of acupuncture machines, in particular to a novel acupuncture device for acupuncture machines. Background Art
[0002] At present, the needle loom is a blanket-making device that compacts and needle-punches a refractory fiber blanket of a certain thickness into a refractory fiber blanket. It uses a triangular or other shaped cross-section and a barbed hook on the edge to repeatedly puncture the fiber web. The fiber web unloaded 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 squeeze the fiber web to a certain extent, causing the fibers in the fiber web to move closer and be compressed.
[0003] Among them, the working principle of the needle loom mainly involves mechanically fixing fiber materials together to form materials with specific structure and strength, such as non-woven fabrics.
[0004] In the market, during the needling process, the needles of the machine will penetrate the fiber web, and the barbed hooks on the needles will drive the fibers on the surface of the fiber web, causing the fibers to shift in the vertical direction, thereby generating compression and increasing the strength and density of the fiber web. However, this operation can only compress the fiber web in one direction, resulting in the fiber web being turned over after processing to ensure its firmness and stability, and being compressed in the opposite direction for a second time, thereby greatly increasing the processing time of the fiber web. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content
[0005] The purpose of the utility model is to provide a new needling device for a needling machine, which solves the problems raised in the background technology.
[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a novel needling device for a needling machine, comprising a mounting frame, a needle plate fixedly mounted in the middle of the mounting frame, a plurality of groups of equally spaced needles fixedly mounted at the bottom of the needle plate, and a repeated thread insertion mechanism mounted on each group of needles;
[0007] The repeated wire insertion mechanism includes multiple groups of equally spaced first barbed hooks provided on the outer wall of the acupuncture needle, second barbed hooks provided between two adjacent groups of the first barbed hooks, a fitting block movably installed in each group of the second barbed hooks, a piston hole provided in the middle of the acupuncture needle, a piston rod movably installed in the piston hole, and multiple groups of equally spaced connecting rods rotatably installed on the piston rod, the other ends of the multiple groups of connecting rods are fixedly installed at one end of each group of fitting blocks, and a driving frame is fixedly installed on the top of the mounting frame.
[0008] As an optional solution of the technical solution of the present application, a piston cylinder is fixedly installed on the bottom side of the inner side of each group of piston holes, and each group of piston cylinders is movably installed on the bottom of multiple groups of piston rods to support the piston rods.
[0009] As an optional solution of the technical solution of the present application, limit sliding grooves are provided on both sides of the interior of the driving frame, and limit sliding blocks are slidably installed in the two groups of the limit sliding grooves, and the push plate can be used for limiting.
[0010] As an optional solution of the technical solution of the present application, a push plate is fixedly installed between the two groups of limit sliders, and the bottom of the push plate is fixedly installed on the top of multiple groups of piston rods and connected to the multiple groups of piston rods.
[0011] As an optional solution of the technical solution of the present application, an electric push rod is fixedly installed on the top of the driving frame, and the bottom of the electric push rod is fixedly installed on the top of the push plate, which can push the push plate to move up and down.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0013] 1. According to the technical solution of the present application, when the needle plate box on the needling machine drives the mounting frame to move upward, it will drive multiple groups of needles to detach from the fiber web, and at the same time drive the electric push rod to press down multiple groups of piston rods, so that the piston rods can drive multiple groups of connecting rods to move downward along the piston holes, so that the fitting blocks installed on the outside of each group of connecting rods are away from the second barbed hooks, so that the second barbed hooks appear on the needles, driving the fibers on the surface of the fiber web, causing the fibers to shift downward in the vertical direction, thereby generating compression, thereby ensuring that the needles on the needle plate can repeatedly compress both sides of the fiber web during the up and down movement, thereby greatly increasing the strength and density of the fiber web.
[0014] 2. The technical solution of this application is to slide limit sliders in two sets of limit slides, and a push plate is fixedly installed between the two sets of limit slides. When the electric push rod is driven to push the push plate up and down, the limit slider in the limit slide can be used to limit the push plate installed between the two sets of limit slides, thereby ensuring that the multiple sets of piston rods at the bottom of the push plate move up and down in the vertical direction.

[0020] The repeated wire insertion mechanism includes multiple groups of equally spaced first barbed hooks 2 provided on the outer wall of the acupuncture 12, second barbed hooks 21 provided between two adjacent groups of first barbed hooks 2, a fitting block 22 movably installed in each group of second barbed hooks 21, a piston hole 23 provided in the middle of the acupuncture 12, a piston rod 24 movably installed in the piston hole 23, and multiple groups of equally spaced connecting rods 25 rotatably installed on the piston rod 24, the other ends of the multiple groups of connecting rods 25 are respectively fixedly installed at one end of each group of fitting blocks 22, a driving frame 3 is fixedly installed on the top of the mounting frame 1, a piston cylinder is fixedly installed on the bottom side of each group of piston holes 23, and each group of piston cylinders is movably installed with the bottom of the multiple groups of piston rods 24, which can support the piston rods 24.
[0021] In this technical solution, when the needle plate 11 box on the mounting frame 1 is driven by the needle punching machine 12 to move upward, it will drive multiple groups of needles to detach from the fiber web, and at the same time drive the electric push rod 34 to press down multiple groups of piston rods 24, so that the piston rods 24 can drive multiple groups of connecting rods 25 to move downward along the piston hole 23, so that the fitting block 22 installed on the outside of each group of connecting rods 25 is away from the second barbed hook 21, so that the second barbed hook 21 appears on the needle, driving the fibers on the surface of the fiber web, causing the fibers to shift downward in the vertical direction, thereby generating compression, thereby ensuring that the needle punching machine 12 on the needle plate 11 can repeatedly compress both sides of the fiber web during the up and down movement, greatly increasing the strength and density of the fiber web.
[0022] In some technical solutions, limiting grooves 31 are provided on both sides of the driving frame 3, and limiting sliders 32 are slidably installed in the two sets of limiting grooves 31, and a push plate 33 can be used for limiting. A push plate 33 is fixedly installed between the two sets of limiting sliders 32, and the bottom of the push plate 33 is fixedly installed on the top of multiple sets of piston rods 24 and is connected to the multiple sets of piston rods 24.
[0023] In this technical solution, when the electric push rod 34 is driven to push the push plate 33 up and down, the limit slider 32 in the limit slide groove 31 can be used to limit the push plate 33 installed between the two groups of limit sliders 32, ensuring that the multiple groups of piston rods 24 at the bottom of the push plate 33 move up and down vertically.

Its structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.
[0027] When in use, the needle plate 11 on the mounting frame 1 is driven by the needle punching machine 12 to move downward, which will press down multiple groups of needles to penetrate the fiber web. The first barbed hook 2 on the needle will drive the fibers on the surface of the fiber web, causing the fibers to shift in the vertical direction, thereby generating compression and increasing the strength of the fiber web. Conversely, when the needle punching machine 12 drives the needle plate 11 on the mounting frame 1 to move upward, it will drive multiple groups of needles to break away from the fiber web, and at the same time drive the electric push rod 34 to press down multiple groups of piston rods 24, so that the piston rods 24 can drive multiple groups of connecting rods 25 to move downward along the piston holes 23, so that the fitting block 22 installed on the outside of each group of connecting rods 25 is away from the second barbed hook 21, so that the second barbed hook 21 appears on the needle. The fibers on the surface of the fiber web are driven to shift downward in the vertical direction, thereby generating compression, thereby ensuring that the needles 12 on the needle plate 11 can repeatedly compress both sides of the fiber web during the up and down movement, greatly increasing the strength and density of the fiber web. At the same time, limiting sliders 32 are slidably installed in the two sets of limiting slides 31, and a push plate 33 is fixedly installed between the two sets of limiting sliders 32. When the electric push rod 34 is driven to push the push plate 33 up and down, the limiting slider 32 in the limiting slide 31 can be used to limit the push plate 33 installed between the two sets of limiting sliders 32, ensuring that the multiple sets of piston rods 24 at the bottom of the push plate 33 move up and down in the vertical direction.
