Description

Technical Field

[0001] The utility model relates to the field of non-woven fabric needling machines, in particular to a needling machine used for non-woven equipment. Background Art

[0002] Since the non-woven equipment needle loom runs at high speed during operation, the gear box is prone to heat up during use. The existing non-woven equipment needle loom gear box is directly bolted to the needle loom frame, so the gear box is subjected to large stress during operation and its life is greatly reduced.

[0003] Therefore, it is necessary to design a needle loom for nonwoven equipment with low stress and long service life. Utility Model Content

[0004] The technical problem to be solved by the present utility model is that the gear box of the existing non-woven equipment needle loom is directly bolted to the needle loom frame. During operation, the gear box is subjected to large forces, has poor heat dissipation, and has a greatly reduced service life. Since the direct bolting to the needle loom frame requires too high machining precision for the gear box, it cannot be mass-produced at present.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a needling machine for non-woven equipment, the needling machine includes a frame, and several groups of relatively designed bearing seats are fixedly installed on the inner bottom of the frame, the several groups of relatively designed bearing seats are arranged in two rows, and gear boxes are arranged between the several groups of relatively designed bearing seats, and a rigid coupling is connected between the shafts between two adjacent bearing seats.

[0006] An oil pressure shock absorber is fixedly installed on the top or bottom of the gear box, and the other end of the oil pressure shock absorber is fixedly installed on the frame.

[0007] The beneficial effects of the utility model are as follows:

[0008] By fixedly connecting the bearing seat to the frame, overhead gearbox, the gearbox main shaft and the eccentric main shaft are connected by a rigid coupling through the bearing seat (reducing the gearbox processing accuracy requirements), the precision error between the shafts is greatly reduced, thereby reducing the shaking of the shaft during rotation. When the needling machine is working, the force on the gearbox becomes smaller and the service life is greatly increased. Since the gearbox body does not need to be directly installed on the needling machine, the volume of the gearbox body can be reduced. Since the force on the gearbox body is greatly reduced, the thickness of the gearbox body can also be reduced, so that the heat dissipation is better and the service life of the gearbox is increased. When the needling machine is working, the gearbox will vibrate, and the oil pressure shock absorber can play a role in buffering and shock absorption. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0013] See also Figure 1-2 The needling machine includes a frame 1, and several groups of relatively designed bearing seats 2 are fixedly installed on the inner bottom of the frame 1. The several groups of relatively designed bearing seats 2 are arranged in two rows, and gear boxes 3 are arranged between the several groups of relatively designed bearing seats 2. The shafts between two adjacent bearing seats 2 are connected with rigid couplings 4 (stable and reliable but with strict requirements on precision); by fixedly connecting the bearing seats 2 to the frame 1, the overhead gear box 3, and the shafts between the bearing seats 2 are connected by a rigid coupling 4, the error between the shafts is greatly reduced, thereby reducing the shaking during shaft rotation. When the needling machine is working, the force on the gear box 3 becomes smaller and its service life is greatly increased. Since the gear box body does not need to be directly installed on the needling machine, the volume of the gear box body can be reduced. Since the force on the gear box body is greatly reduced, the thickness of the gear box body can also be reduced, so that the heat dissipation is better and the gear box life is increased.

[0014] A hydraulic shock absorber 5 is fixedly installed on the top or bottom of the gear box 3, and the other end of the hydraulic shock absorber 5 is fixedly installed on the frame 1; when the needling machine is working, the gear box 3 will vibrate, and the hydraulic shock absorber 5 can play a role in buffering and shock absorption.

[0015] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
