Description

Technical Field

[0001] This utility model relates to the field of air-jet loom technology, and in particular to a novel frame for an air-jet loom with airbag fabric. Background Technology

[0002] Conjugate cam air-jet looms, due to their high weft-beating force and long weft-in time, can meet the requirements for weaving heavy fabrics. The frame structure of an air-jet loom is as follows: Figure 1 and Figure 2 As shown, the left and right wall panels and the left and right bases are usually connected only by four parallel crossbeams. This frame structure can accommodate ordinary tension fabrics, but it is relatively weak for airbag fabrics with extremely high tension. Therefore, the frame structure of existing looms cannot meet the requirements of the ultra-high upholstery tension of automotive airbag fabrics. Utility Model Content

[0003] This invention provides a novel frame for an air-jet loom for airbag fabric, which solves the problem that the existing air-jet loom frames have low strength and cannot meet the ultra-high tension requirements for weaving airbag fabric.

[0004] This utility model provides a novel frame for an air-jet loom, including a left wall assembly, a right wall assembly, and a crossbeam assembly connecting the left and right wall assemblies; the left wall assembly includes a left wall panel and a left base connected below it, the right wall assembly includes a right wall panel and a right base connected below it, and the crossbeam assembly includes a front upper beam, a rear upper beam, a front lower beam, and a rear lower beam arranged parallel to the left and right wall assemblies; reinforcing members are also installed on the end faces of the left and right wall panels near the rear upper beam; a first intermediate connecting member is also installed between the front upper beam, the rear upper beam, the front lower beam, and the rear lower beam, and a second intermediate connecting member is installed between the front lower beam and the rear lower beam.

[0005] Optionally, the reinforcement includes a left bracket mounted on the left end face of the left wall panel, a right bracket mounted on the right end face of the right wall panel, and a reinforcing beam connecting the left and right brackets.

[0006] Optionally, the first intermediate connecting member includes a front connecting frame connecting the front upper beam and the front lower beam, a rear connecting frame connecting the rear upper beam and the rear lower beam, and an intermediate connecting plate connecting the front connecting frame and the rear connecting frame.

[0007] Optionally, a reinforcing connecting frame is also connected between the front connecting frame and the extension of the front upper beam bottom plate, and a clearance groove for installing the drive shaft is also formed between the front connecting frame and the reinforcing connecting frame.

[0008] Optionally, the upper and lower edges of the intermediate connecting plate are both machined into bevels.

[0009] Optionally, multiple first intermediate connectors are provided along the length of the loom.

[0010] Optionally, the second intermediate connector includes a lower connecting plate that connects the front lower beam and the rear lower beam, with an intermediate foot plate installed at each end of the lower connecting plate.

[0011] Optionally, multiple second intermediate connectors are provided along the length of the loom.

[0012] Optionally, both the front and rear lower beams are made of H-beams, with the upper parts of both ends of the H-beams connected to the left and right wall panels respectively, and the lower parts of both ends of the H-beams connected to the left and right bases respectively.

[0013] Optionally, both the left and right bases have multiple foot connection holes at their bottoms.

[0014] The beneficial effects of the novel air-jet loom frame provided by this utility model are as follows:

[0015] 1. The new frame has high strength and high rigidity through the setting of reinforcing parts, first intermediate connecting parts and second intermediate connecting parts, which improves the deformation resistance under extreme tension. It can provide a stable and reliable basic frame for air-jet looms to manufacture one-piece molded airbag fabric. Based on this, air-jet looms can be developed to produce airbag fabric air-jet looms with large jacquard openings.

[0016] 2. Through the coordinated action of the front connecting frame, rear connecting frame and intermediate connecting plate in the first intermediate connecting component, the four crossbeams become a whole, thereby improving the rigidity of the frame; the upper and lower ends of the intermediate connecting plate are designed as bevels to facilitate the up and down movement of the jacquard opening and reduce friction; the setting of the reinforced connecting frame increases the rigidity of the front upper beam bottom plate, thereby ensuring the support strength of the weft insertion shaft seat mounted on the front upper beam bottom plate, and at the same time, the reinforced connecting frame and the front connecting frame form a relief groove to facilitate the disassembly and assembly of the main drive shaft.

[0017] 3. The front lower beam and the rear lower beam are connected by the lower connecting plate in the second intermediate connecting piece, which improves the rigidity of the connection between the two lower beams; the frame is connected to the ground by the intermediate foot plate, thereby improving the stability of the connection between the frame and the ground.

[0018] 4. By installing reinforcements on the relatively weak upper rear part of the loom, the connection strength between the left and right wall panels is improved by the reinforcing beam. At the same time, the great tension of the loom warp yarns acts on the left and right supports. This structure can effectively improve the support capacity of the rear of the wall panels.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this utility model.

[0031] like Figure 3-8 As shown, this utility model provides a novel frame for an air-jet loom, including a left wall assembly 1, a right wall assembly 2, and a crossbeam assembly 3 connecting the left wall assembly 1 and the right wall assembly 2; the left wall assembly 1 includes a left wall panel 11 and a left base 12 connected below it, the right wall assembly 2 includes a right wall panel 21 and a right base 22 connected below it, and the crossbeam assembly 3 includes a front upper beam 31, a rear upper beam 32, a front lower beam 33, and a rear lower beam 34 arranged parallel between the left wall assembly 1 and the right wall assembly 2; a reinforcing member 4 is also installed on the end face of the left wall panel 11 and the right wall panel 21 near the rear upper beam 32; a first intermediate connecting member 5 is also installed between the front upper beam 31, the rear upper beam 32, the front lower beam 33, and the rear lower beam 34, and a second intermediate connecting member 6 is installed between the front lower beam 33 and the rear lower beam 34.

[0032] The new frame of the air-jet loom for air-cushioned fabric consists of a left wall assembly 1, a right wall assembly 2, and a crossbeam assembly 3, forming the basic structure of the new frame. The left wall panel 11 and the left base 12 in the left wall assembly 1 are firmly connected vertically, and similarly, the right wall panel 21 and the right base 22 in the right wall assembly 2 are also firmly connected vertically. The two wall assemblies, left wall assembly 1 and right wall assembly 2, are then fixedly connected by four crossbeams in the crossbeam assembly 3: front upper beam 31, rear upper beam 32, front lower beam 33, and rear lower beam 34, ensuring the stability of the new frame and increasing its resistance to deformation. The four crossbeams are positioned between the two wall assemblies in four directions, as their names suggest: front upper, front front, front lower, and rear lower.

[0033] The reinforcing members 4 installed on the end faces of the left wall panel 11 and the right wall panel 21 near the rear upper beam 32 are used to reinforce the warp feed roller support section and prevent deformation due to insufficient rigidity. Simultaneously, since the rear upper part of the loom is relatively weak, the reinforcing members 4 can also improve the connection strength of the rear part of the wall panel. The first intermediate connector 5, located between the four crossbeams, firmly connects the four crossbeams together, improving rigidity without affecting the arrangement of the jacquard opening return spring. The second intermediate connector 6, located below the front lower beam 33 and the rear lower beam 33, increases the connection strength between the front and rear lower beams and also connects the frame to the ground, increasing the stability of the new frame's connection to the ground.

[0034] The novel frame of the airbag fabric air-jet loom provided by this utility model has high strength and high rigidity, and can provide a stable and reliable basic frame for the air-jet loom to manufacture one-piece molded safety airbag fabric. Based on this, the air-jet loom can be developed to produce airbag fabric air-jet looms with large jacquard openings.

[0035] like Figure 3 As shown, the reinforcing member 4 further includes a left bracket 41 installed on the end face of the left wall panel 11, a right bracket 42 installed on the end face of the right wall panel 21, and a reinforcing beam 43 connecting the left bracket 41 and the right bracket 42.

[0036] The reinforcing member 4 is used to strengthen the support portion of the warp feed roller. Specifically, the reinforcing beam 43 is jointly supported by the left bracket 41 installed on the end face of the left wall panel 11 and the right bracket 42 installed on the end face of the right wall panel 21, and then the support portion of the warp feed roller is reinforced by the reinforcing beam 43. The reinforcing beam 43 is installed in the relatively weak upper rear part of the loom, which can improve the connection strength between the left wall panel 11 and the right wall panel 21. At the same time, the great tension of the warp yarns of the loom acts on the left bracket 41 and the right bracket 42. This structure can effectively improve the support capacity of the rear part of the wall panel.

[0037] like Figure 3 , Figure 5 and Figure 6 As shown, the first intermediate connecting member 5 further includes a front connecting frame 51 connecting the front upper beam 31 and the front lower beam 33, a rear connecting frame 52 connecting the rear upper beam 32 and the rear lower beam 34, and an intermediate connecting plate 53 connecting the front connecting frame 51 and the rear connecting frame 52. Furthermore, a reinforcing connecting frame 54 is also connected between the front connecting frame 51 and the extension of the bottom plate of the front upper beam 31, and a clearance groove 55 for mounting the drive shaft is formed between the front connecting frame 51 and the reinforcing connecting frame 54.

[0038] The first intermediate connector 5 is used to firmly connect the four crossbeams together, thereby improving the rigidity of the frame. Specifically, the front connecting frame 51 connects the front upper beam 31 and the front lower beam 33, the rear connecting frame 52 connects the rear upper beam 32 and the rear lower beam 34, and then the intermediate connecting plate 53 connects the front connecting frame 51 and the rear connecting frame 52. In this way, the four crossbeams are formed as a whole through the first intermediate connector 5, thereby improving the rigidity of the frame.

[0039] Meanwhile, the reinforcing connecting bracket 54 connects the front connecting bracket 51 to the extension of the front upper beam 31 base plate, increasing the rigidity of the front upper beam 31 base plate and thus ensuring the support strength of the weft shaft seat mounted on the front upper beam 31 base plate. Additionally, a clearance groove 55 is formed between the reinforcing connecting bracket 54 and the front connecting bracket 51, which facilitates the disassembly and assembly of the main drive shaft.

[0040] like Figure 7 As shown in Tianyu 8, furthermore, the upper and lower edges of the intermediate connecting plate 53 are both machined into bevels.

[0041] The upper and lower ends of the intermediate connecting plate 53 are designed with bevels to guide the up-and-down movement of the jacquard opening and reduce friction.

[0042] Furthermore, multiple first intermediate connectors 5 are provided along the length direction of the loom.

[0043] The first intermediate connecting piece 5 is provided in several parts along the length of the loom (more precisely, the frame), and the number of parts varies depending on the width of the loom reed.

[0044] like Figure 4 and Figure 6 As shown, the second intermediate connector 6 further includes a lower connecting plate 61 that connects the front lower beam 33 and the rear lower beam 34, and an intermediate foot plate 62 is installed at each end of the lower connecting plate 61.

[0045] The second intermediate connector 6 primarily enhances the connection strength between the front lower beam 33 and the rear lower beam 34, while also improving the stability of the connection between the frame and the ground. Specifically, the lower connecting plate 61 connects the front lower beam 33 and the rear lower beam 34, thereby increasing the rigidity of the connection between the two lower beams. Then, the intermediate foot plates 62 installed at both ends of the lower connecting plate 61 connect the frame to the ground, thereby improving the stability of the connection between the frame and the ground.

[0046] Furthermore, multiple second intermediate connectors 6 are provided along the length direction of the loom.

[0047] Similar to the first intermediate connector 5, multiple second intermediate connectors are also provided along the length of the frame, and the number of second intermediate connectors 6 varies depending on the reed width of the loom.

[0048] like Figure 4 and Figure 6 As shown, both the front lower beam 33 and the rear lower beam 34 are made of H-beams. The upper parts of both ends of the H-beams are connected to the left wall panel 11 and the right wall panel 21, respectively, and the lower parts of both ends of the H-beams are connected to the left base 12 and the right base 22, respectively.

[0049] The front lower beam 33 and rear lower beam 34 in the new frame are made of high-strength, large-sized H-beams. These H-beams are quite tall, with the upper part of one end connected to the left wall panel 11 and the lower part connected to the left base 12. The upper and lower parts of the other end are connected to the right wall panel 21 and the right base 22, respectively. In other words, the front lower beam 33 and rear lower beam 34 firmly connect the wall panels and the base together, thereby improving the frame's rigidity.

[0050] like Figure 4As shown, both the left base 12 and the right base 22 have multiple foot connection holes 7 at their bottoms.

[0051] The foot connection holes 7 at the bottom of the left base 12 and the right base 22 are used to connect the rack to the ground, thereby improving the stability of the rack during installation and use.

[0052] It should be noted that the beat-up shaft bearing, main drive shaft, and loom reed width mentioned above are all well-known in the field and are familiar to those skilled in the art, and will not be elaborated upon here.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
