Detailed implementation mode

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0020] As Figures 1 to 4 shown, a needle punching machine includes a machine body 2. The machine body 2 includes a feeding port 21 and a discharging port 22. A first hydraulic cylinder 31 and a second hydraulic cylinder 32 surrounding the first hydraulic cylinder 31 are further installed on the machine body 2. Mounting plates 33 are fixed to both the first hydraulic cylinder 31 and the second hydraulic cylinder 32. A disassembly and assembly table 34 is detachably connected to the mounting plate 33. Needle punching seats 35 are also detachably connected and arranged on the disassembly and assembly table 34. A number of needle points 362 for puncturing the fiber blanket are provided on the needle punching seats 35;

[0021] A protection plate 4 is further installed in the machine body 2. The protection plate 4 is located directly below the needle punching seats 35 and a number of needle points 362 and directly above the material 7. A number of first through holes 41 through which the needle points 362 can pass are opened on the protection plate 4; The needle points 362 are aligned with the corresponding first through holes 41 on the protection plate 4.

[0022] A tray mechanism is further included in the machine body 2. The tray mechanism includes a bottom frame 51. A number of lifting motors 52 are installed in the bottom frame 51. A shock absorber 53 is fixed to the lifting rod of the lifting motor 52. A bottom plate 54 is fixed to the shock absorber 53. The bottom plate 54 is located directly below the material 7.

[0023] In the present utility model, the shock absorber 53 is a prior art. The shock absorber 53 includes a spring and a damper, which are used to effectively reduce the vibration of the bottom plate 54 when the needle punching machine works and touches the bottom plate 54, extend the service life of the device, and make it safer.

[0024] With the above structure, the mounting plate 33 is driven to rise or fall by the first hydraulic cylinder 31 and the second hydraulic cylinder 32. If some of the needles 362 on all the needle seats 35 on the disassembly and assembly table 34 are worn, broken, or the angle of the needles 362 is offset and need to be replaced, the disassembly and assembly table 34 can be directly removed from the mounting plate 33 for overall replacement, which is conducive to more convenient replacement. If some of the needles 362 on any one or two of the needle seats 35 on the disassembly and assembly table 34 are worn, broken, or the angle of the needles 362 is offset, through the several detachably mounted needle seats 35 provided on the disassembly and assembly table 34, the waste caused by overall replacement can be avoided. The needle seat 35 that needs to be replaced can be removed from the disassembly and assembly table 34 and replaced with new needles 362 that can be used normally, which is conducive to avoiding the waste caused by overall replacement, greatly reducing the replacement cost, making the replacement more convenient, and avoiding waste.

[0025] As Figures 1 to 4 shown, second connecting blocks 37 are detachably mounted on both the front and rear sides of the needle seat 35. The second connecting blocks 37 are hinged with third connecting blocks 38, and the third connecting blocks 38 are fixed on both the front and rear sides of the needle seat 35 by first screws 39.

[0026] As Figures 1 to 4 shown, the needle seat 35 is provided with a first groove 351. Guide rails 352 are symmetrically arranged in the first groove 351. The needle member 362 includes a sliding plate 361 and needles 362. The guide rails 352 are in sliding fit with the sliding plate 361, and a number of needles 362 are arranged and fixed on the sliding plate 361.

[0027] With the above structure, before the detachably mounted needle seat 35 is assembled to the disassembly and assembly table 34, the second connecting blocks 37 and the two sides of the needle seat 35 are also connected by fourth screws. The operator can first remove the fourth screws on both sides of the needle seat 35, thereby removing the second connecting blocks 37. Subsequently, the needle member 362 is sent into the needle seat 35. At this time, the sliding plate 361 is in sliding fit with the guide rails 352, which is conducive to quickly sending the needle member 362 into the first groove 351 of the needle seat 35. The principle of sending the needle member 362 out of the needle seat 35 is the same. The second connecting blocks 37 and the two sides of the needle seat 35 are also connected by fourth screws. Subsequently, the second connecting blocks 37 are reassembled on the needle seat 35 through the fourth screws, which is conducive to more convenient replacement of the needle member 362 and firm fixation. When the needle seat 35 is installed on the disassembly and assembly table 34, the third connecting blocks 38 are flipped on one side of the second connecting blocks 37 until they are close to the side wall on one side of the disassembly and assembly table 34. Then, the third connecting blocks 38 on both sides are connected and fixed to both sides of the disassembly and assembly, which is conducive to convenient disassembly, assembly, and replacement of the needle seat 35 according to actual needs, and has stronger practicability.

[0028] As shown Figures 1 to 4 In the figure, fixed seats 331 are symmetrically arranged on both the left and right sides of the mounting plate 33. First rotating plates 341 are rotatably arranged on both the left and right sides of the disassembly and assembly table 34. A first connecting block 342 matching the fixed seat 331 is provided on the first rotating plate 341. The fixed seat 331 passes through one side of the fixed seat 331, the first connecting block 342, and the other side of the fixed seat 331 in sequence through bolts to fix the first connecting block 342.

[0029] With the above structure, when installing the disassembly and assembly table 34 onto the mounting plate 33, the first rotating plates 341 on both sides of the disassembly and assembly table 34 can be flipped until the first rotating plates 341 are flipped and abutted against one side of the fixed seat 331 on the mounting plate 33. Second through holes are provided on both the fixed seat 331 and the first rotating plate 341. Then, bolts are passed through one side of the fixed seat 331, the first connecting block 342, and the other side of the fixed seat 331 in sequence and fixed, which is beneficial to firm fixation, more convenient for overall replacement of the disassembly and assembly table 34, and has strong practicability.

[0030] As shown Figures 1 to 4 In the figure, threaded holes are provided on both the front and rear sides of the disassembly and assembly table 34, and the first screw 39 is threadedly connected in the threaded holes of the disassembly and assembly table 34.

[0031] With the above structure, when installing one of the acupuncture seats 35, since a number of threaded holes are provided on the disassembly and assembly table 34 for installing the acupuncture seat 35, the third connecting blocks 38 provided on both sides of the acupuncture seat 35 can be fixed on the disassembly and assembly table 34 through the first screws 39. The first screws 39 are threadedly connected in the threaded holes of the disassembly and assembly table 34, which is beneficial to firm fixation, stable structure, and simple and convenient installation.

[0032] As shown Figures 1 to 4 In the figure, the protection plate 4 is detachably connected to the inside of the machine body 2 through the second screw 6. By detachably connecting the protection plate 4 to the inside of the machine body 2, if it is necessary to use a thicker or thinner acupuncture needle 362, and the first through hole 41 on the protection plate 4 is not universal, then the protection plate 4 also needs to be replaced, which is beneficial to replacement according to needs, convenient replacement, and has strong practicability.
