Description

Technical Field

[0001] This utility model relates to the field of needle punching machine technology, specifically to a needle punching machine for processing carbon fiber products. Background Technology

[0002] A needle-punching machine is a blanket-forming device that compresses and needles refractory fiber blanket blanks of a certain thickness to form refractory fiber blankets. It utilizes needles with triangular or other shaped cross-sections and barbs on their edges to repeatedly pierce the fiber web. The fiber web, fed into the needle-punching machine from a cross-linking or air-laid machine, is very loose, possessing only a certain strength generated by the cohesion between fibers, but this strength is very weak. When multiple needles pierce the fiber web, the barbs on the needles cause the fibers on the surface and subsurface of the web to move from the planar direction to the vertical direction, causing the fibers to shift vertically. This vertical displacement of the fibers exerts a certain amount of pressure on the web, causing the fibers within the web to clump together and be compressed.

[0003] However, in existing needle punching machines, the corresponding needle punching mechanism is fixed to the support plate. When the support plate and base need to be disassembled for maintenance and reassembled, the positioning is cumbersome, affecting assembly efficiency. Therefore, those skilled in the art have provided a needle punching machine for processing carbon fiber products to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a needle punching machine for processing carbon fiber products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A needle punching machine for processing carbon fiber products includes a support plate, a base connected to the bottom of the support plate, a needle punching mechanism installed between corresponding surfaces of the two support plates, a metal crossbar connected between corresponding surfaces of the two support plates, and a positioning device provided on the top of the base.

[0007] The positioning device includes a movable block, a metal handle connected to one side of the movable block, a guide groove on the top of the base, a movable sleeve connected to the outside of the movable block, a positioning pad connected to one side of the support plate, a fixed column connected to the top of the positioning pad, a shielding pad installed on the top of the fixed column, a positioning clip movably sleeved on the outside of the fixed column, and a positioning groove inside the movable sleeve.

[0008] As a further improvement of this utility model: the movable block and the metal handle are bonded and fixed together, and a groove adapted to the size of the fixed post is provided on the outer side of the movable sleeve.

[0009] As a further improvement of this utility model: the size of the positioning block is adapted to the size of the positioning groove, and the base is slidably connected to the moving block through the guide groove.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This device is equipped with a positioning device. After the support plate and the base are disassembled, the needle punching mechanism between the two support plates can be maintained and repaired. After maintenance, when the support plate and the base need to be reassembled and positioned, the positioning between the support plate and the base can be completed quickly. After positioning, bolts can be used to fix it, avoiding the cumbersome positioning and fixing situation, improving maintenance efficiency, and facilitating the processing of carbon fiber products.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-2 In this embodiment of the present invention, a needle punching machine for processing carbon fiber products includes a support plate 1, a base 2 connected to the bottom of the support plate 1, a needle punching mechanism 3 installed between the corresponding surfaces of the two support plates 1, a metal crossbar 4 connected between the corresponding surfaces of the two support plates 1, and a positioning device 5 provided on the top of the base 2.

[0017] The positioning device 5 includes a movable block 51, a metal handle 52 connected to one side of the movable block 51, a guide groove 53 on the top of the base 2, a movable sleeve 54 connected to the outer side of the movable block 51, a positioning pad 55 connected to one side of the support plate 1, a fixing post 56 connected to the top of the positioning pad 55, a shielding pad 57 installed on the top of the fixing post 56, the movable block 51 and the metal handle 52 are bonded together, the outer side of the movable sleeve 54 has a groove adapted to the size of the fixing post 56, a positioning block 58 is movably sleeved on the outer side of the fixing post 56, a positioning groove 59 is opened inside the movable sleeve 54, the size of the positioning block 58 and the size of the positioning groove 59 are adapted, the base 2 is slidably connected to the movable block 51 through the guide groove 53, when the support plate 1 and the base 2 are disassembled, the needle-punching mechanism 3 between the two support plates 1 can be maintained. For maintenance and repair, when it is necessary to reassemble and position the support plate 1 and the base 2 after maintenance, the support plate 1 can be placed on top of the base 2. At this time, the bottom surface of the positioning pad 55 on the outside of the support plate 1 is in contact with the top surface of the base 2. Then, move the positioning block 58 on the outside of the fixing post 56 upward to avoid the positioning block 58 from blocking the moving sleeve 54. Then, push the metal handle 52 horizontally to move the moving block 51 and the moving sleeve 54, so that the moving sleeve 54 is movably fitted onto the outside of the fixing post 56.
