[0002] In the fiber processing industry, the needle loom is an important equipment, which is mainly used to reinforce and connect fiber raw materials by needle punching to form nonwoven materials with certain strength and thickness. However, in the use of the needle loom, especially on the output side, the tension and support of the fiber web is an important technical challenge.

At this time, the fiber mesh on the surface of the tensioning roller 313 continuously tightens and relaxes the fiber mesh, and through reciprocating operation, dynamic adjustment of the tension of the fiber mesh is achieved.

[0037] Embodiment 3, refer to the attached Figure 1-16On the basis of the second embodiment, in order to realize the assembly of the eccentric shaft 312 and the tensioning roller 313: the outer surfaces of both sides of the sleeve ring plate 4 are respectively fixedly installed with a convex ring plate 1 41 and a convex ring plate 2 42, the convex ring plate 1 41, the sleeve ring plate 4 and the convex ring plate 2 42 are an integrally formed welding structure, and an insertion rod 3122 is fixedly installed on the inner side wall of the convex ring plate 1 41, and the insertion rod 3122 is provided in multiple groups and arranged in a circular array with respect to the central axis of the eccentric shaft 312, and the outer surfaces of the insertion rod 3122 are respectively movably plugged with the inner walls of the flange plate 1 3121 and the flange plate 2 3131, and the inner ring surface of the convex ring plate 1 41 is fixedly installed with a square insert 411, and the outer surface of the square insert 411 is movably plugged with the inner wall of the square embedding groove 3132, and the rotating disk 311 is rotated. A protective cover 6 is detachably installed on the outside, and one side of the protective cover 6 is fixedly connected to the outer surface of the support frame 22. An oil pipeline is penetrated and connected to the upper end of the protective cover 6. A solenoid valve is arranged on the inner side wall of the oil pipeline, and a nozzle is sealed and connected to the output end of the oil pipeline. A telescopic cylinder 7 is fixedly provided on the outer surface of one side of the sleeve ring plate 4 close to the convex ring plate 42. Fixed rings are respectively arranged at both ends of the telescopic cylinder 7. The telescopic cylinder 7 and the fixed ring are respectively coaxially distributed with respect to the eccentric shaft 312. In this embodiment, the protection cover 6 is provided to protect the operation of the rotating disk 311 to avoid the teeth of the rotating disk 311. The telescopic cylinder 7 is additionally provided on the outer wall of the sleeve ring plate 4 close to the rotating disk 311, so as to connect the eccentric shaft 312 and the convex ring plate 42. The dustproof treatment is performed at the place, which further prevents the fiber debris generated during the transmission of the fiber web from causing the rotating disk 311 to jam during the operation. At the same time, the locking assembly 43 can be retracted and shielded as a whole, which further improves the dustproof effect, facilitates daily maintenance, and reduces the pressure of subsequent cleaning. Before or after the use of the fiber web bracket, the eccentric shaft rod 312 and the tensioning roller 313 are disassembled and assembled. At this time, the sleeve ring plate 4 is always sleeved on the surface of the eccentric shaft rod 312 as a whole. When it is necessary to assemble the two, the flange plates 2 3131 at both ends of the tensioning roller 313 are aligned with the flange plate 1 3121 at one end of the eccentric shaft rod 312. Then, the sleeve ring plate 4 is manually moved as a whole to one side of the tensioning roller 313, and the sleeve ring plate 4 is on the eccentric shaft rod 312 When the eccentric shaft 312 and the tension roller 313 are in a state of being disengaged from each other, the eccentric shaft 312 and the tension roller 313 are in a state of being disengaged from each other.Through the above arrangement, the sleeve ring plate 4 can not only realize the compensatory assembly of the eccentric shaft 312 and the tensioning roller 313, but also serve as the limiters on both sides of the tensioning roller 313 to limit the positions of both sides of the fiber web, thereby preventing the fiber web from being offset during transportation, further improving the production quality of the fiber web, and thus realizing the multifunctionality of the sleeve ring plate 4. ;

[0038] Embodiment 4, refer to the attached Figure 1-16 On the basis of the third embodiment, in order to realize the locking between the sleeve ring plate 4 and the eccentric shaft 312: the inner surface of the sleeve ring plate 4 and the convex ring plate 42 are movably connected to the outer surface of the eccentric shaft 312, and the outer ring surface of the convex ring plate 42 is provided with a receiving groove 421, and the inner cavity of the receiving groove 421 is provided with a locking assembly 43, and the locking assembly 43 includes a mounting block 431, and the mounting block 431 is fixedly mounted on the inner wall of the receiving groove 421, and a turning handle rod 432 is rotatably connected to the inner wall of the upper end of the mounting block 431, and an abutting rod 433 is fixedly connected to the outer surface of the upper end of the turning handle rod 432, and the abutting rod 433 is away from the turning handle rod A soft rubber block 4331 is fixedly provided on the lower surface of one end of 432, and a locking plate 435 is provided on one side of the mounting block 431. A pin 434 is rotatably connected to the inner wall of one end of the locking plate 435. The two ends of the pin 434 are respectively fixedly connected to the inner wall of the receiving groove 421. An insert block 436 is fixedly installed on the lower surface of the end of the locking plate 435 away from the pin 434. The outer surface of the insert block 436 is movably plugged into the inner wall of the slot 3111. In this embodiment, after the eccentric shaft rod 312 and the tensioning roller 313 are assembled, the handle rod 432 is manually rotated to rotate the abutment rod 433. At this time, the abutment rod 433 The soft rubber block 4331 at the lower end contacts the upper inclined surface of the locking plate 435, and one end of the locking plate 435 rotates with the pin 434. After the locking plate 435 is subjected to pressure from above, the plug block 436 is squeezed into the interior of the slot 3111, so as to clamp and assemble the eccentric shaft rod 312. Through such an arrangement, the locking between the sleeve ring plate 4 and the eccentric shaft rod 312 as a whole is achieved, which can effectively prevent the sleeve ring plate 4 from loosening after assembly, and realize the locking and braking of the sleeve ring plate 4; conversely, when it is necessary to disassemble the eccentric shaft rod 312 and the tensioning roller 313, it is first necessary to lock the plug of the eccentric shaft rod 312 The restriction of block 436 is released by manually rotating the handle rod 432, so that the abutment rod 433 is pushed in both directions, and the restriction of the abutment rod 433 is released above the locking plate 435. At this time, the locking plate 435 drives the plug block 436 to rotate upward around the pin shaft 434, thereby achieving separation from the eccentric shaft rod 312; after multiple sets of locking plates 435 are clamped with the eccentric shaft rod 312, the fixing ring on one side of the sleeve ring plate 4 is manually stretched to expand the telescopic cylinder 7, thereby covering the connection between the convex ring plate 42 and the eccentric shaft rod 312 to prevent the entry of external fiber debris and affect the subsequent maintenance effect.

[0039] Embodiment 5, refer to the attached Figure 1-16 On the basis of the fourth embodiment, in order to realize the convenient movement of the fiber net support mechanism 2 as a whole: the support movable unit 5 includes a limited hook plate 51, the limited hook plate 51 is fixedly installed on the inner side of the connecting rail 11, and a notch 511 is provided at the upper end of the limited hook plate 51, and a fixed seat 52 is fixedly installed on the inner wall of the lower end of the limited hook plate 51, and an articulated arm rod 53 is rotatably installed on the outer surface of the fixed seat 52, and an avoidance arc groove 211 is provided on the inner wall of one side of the movable base 21, and the outer surface of the articulated arm rod 53 is movably abutted against the inner ring surface of the avoidance arc groove 211, and a threaded column 531 is fixedly added to the end of the articulated arm rod 53 away from the fixed seat 52, and a locking nut 54 is threadedly connected to the outer surface of the articulated arm rod 53, and the lower surface of the locking nut 54 is movably abutted against the upper surface of the movable base 21; in this embodiment, when the fiber net support mechanism 2 as a whole needs to be used, the whole is moved, and the fiber net support mechanism 2 as a whole is moved by relying on the moving wheel 210 set at the lower end of the movable base 21. The movable base 21 is pushed and replaced with a structure that replaces the traditional fixed bracket, which is convenient for transportation and daily maintenance. When the fiber mesh support mechanism 2 is transported to the specified position as a whole, the inner surface of the movable base 21 slides over the connecting rail 11, and then the articulated arm 53 set on one side is manually moved, and moves toward the inner wall of the avoidance arc groove 211 preset on one side of the movable base 21, and then the locking nut 54 is manually rotated so that the locking nut 54 is threadedly adapted along the surface of the threaded column 531, and the locking nut 54 gradually moves downward, so that the locking nut 54 is close to the upper end of the limiting hook plate 51, so that the articulated arm 53 clamps the movable base 21. Through such a design, the free movement and locking of the fiber mesh support mechanism 2 as a whole can be effectively realized, ensuring stable operation in the working state, and the fiber mesh support mechanism 2 can be moved to one side when not working, reducing the floor space of the workshop, further solving the problem that the existing fiber mesh support is large in size and difficult to maintain, and realizing convenient maintenance of the fiber mesh support as a whole.

[0040] The working principle and use process of the present invention are as follows: in actual operation, first, the fiber net support mechanism 2 is moved as a whole, and the fiber net support mechanism 2 is pushed as a whole by the moving wheel 210 provided at the lower end of the movable base 21, replacing the structure of the traditional fixed support, which is convenient for transportation and daily maintenance. When the fiber net support mechanism 2 is transported as a whole to the specified position, the inner surface of the movable base 21 slides above the connecting rail 11, and then the articulated arm 53 provided on one side is manually moved, and moves to the inner wall of the avoidance arc groove 211 preset on one side of the movable base 21, and then the locking nut 54 is manually rotated so that the locking nut 54 is threadedly adapted along the surface of the threaded column 531, and the locking nut 54 is gradually downward, thereby making the locking nut The nut 54 is in close contact with the upper end of the limiting hook plate 51, so that the articulated arm rod 53 clamps the movable base 21. Through such a design, the free movement and locking of the fiber web support mechanism 2 as a whole can be effectively realized, ensuring stable operation in the working state; furthermore, the fiber web after acupuncture and shaping on a part of the output side of the needle loom body 1 is stretched, and the upper part of the guide roller 231 and the lower part of the tensioning roller 313 are successively passed through, and finally wound with the winding mechanism set on one side. At this time, before or after the use of the fiber web support, the eccentric shaft rod 312 and the tensioning roller 313 are disassembled and assembled. At this time, the sleeve ring plate 4 is always sleeved on the surface of the eccentric shaft rod 312 as a whole. When it is necessary to assemble the two, the tensioning roller 313 is The flanges 3131 at both ends are aligned with the flanges 3121 at one end of the eccentric shaft 312, and then the sleeve ring plate 4 is manually moved to move toward the side of the tensioning roller 313 as a whole, and the sleeve ring plate 4 slides on the surface of the eccentric shaft 312. After moving a certain distance, the insertion rod 3122 installed on the inner side wall of the convex ring plate 1 41 is aligned with and inserted into the flange hole between the flange 1 3121 and the flange 2 3131. At this time, the eccentric shaft 312 and the tensioning roller 313 are initially limited by the insertion rod 3122. When the sleeve ring plate 4 is continued to be moved forward, the square insert 411 installed on the inner annular surface of the convex ring plate 1 41 is adapted and plugged into the inner wall of the square insert groove 3132 opened at one end of the tensioning roller 313, thereby achieving Double limit of the eccentric shaft rod 312 and the tensioning roller 313; in addition, after the eccentric shaft rod 312 and the tensioning roller 313 are assembled, the handle rod 432 is manually rotated to rotate the abutment rod 433. At this time, the soft rubber block 4331 at the lower end of the abutment rod 433 contacts the upper inclined surface of the locking plate 435, and one end of the locking plate 435 rotates with the pin shaft 434. After the locking plate 435 is subjected to pressure from above, the plug block 436 is squeezed into the interior of the slot 3111, so as to clamp and assemble the eccentric shaft rod 312. Through such a setting, the locking between the entire sleeve ring plate 4 and the eccentric shaft rod 312 is achieved, which can effectively prevent the sleeve ring plate 4 from loosening after assembly, and realize the locking and braking of the sleeve ring plate 4.
