[0002] Traditional jacquard machines mostly use stand-shaft structures for transmission, but such structures have obvious limitations. First, stand-shaft transmission efficiency is relatively low, and it is prone to become a high-incidence point of mechanical failures. Second, once the stand-shaft is damaged, the replacement cost is high, and it will seriously delay the production progress. In addition, the maintenance and maintenance of the jacquard machine with a stand-shaft structure are relatively complex, which increases the operating cost of the enterprise. In view of the limitations of the traditional stand-shaft jacquard machine, the demand for non-stand-shaft jacquard machine driving devices in the market is increasing. The non-stand-shaft design can simplify the mechanical structure, improve the transmission efficiency, reduce the failure rate, and reduce the maintenance and maintenance cost. At the same time, the non-stand-shaft jacquard machine also has better flexibility and adaptability, which can meet the production needs of different specifications and types of fabrics.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme of the present application clear, complete description, and the advantages are more clear and obvious, the following will be further described in detail with the help of the attached drawings. It should be understood that the specific embodiments described here are part of the embodiments of the present application, not all the embodiments, only to explain the embodiments of the present application, and not for the limitation of the embodiments of the present application, all other embodiments obtained by the ordinary skill in the art without doing creative work, belong to the scope of protection of the present application.

[0038] Embodiment one, please refer to Figures 1 to 19 The present application provides a technical scheme: a driving device for large-scale non-vertical axis pattern machine, comprising a mounting side plate 1, a support vertical plate 11 is fixedly installed on the inner side of the mounting side plate 1, a gear piece is arranged on the support vertical plate 11, a swing boom 2 is rotatably connected to the outer surface of the gear piece, a boom swing shaft 21 is fixedly connected to the other end of the swing boom 2, a lifting pattern plate 12 is movably connected to the both sides of the boom swing shaft 21, the lifting pattern plate 12 is movably installed on the inner side of the support vertical plate 11, an embedded groove 120 is formed on the lifting pattern plate 12, a compensation plate 121 is movably embedded in the inner side of the embedded groove 120, a boom protection mechanism is arranged on the lifting pattern plate 12 and the compensation plate 121, the boom protection mechanism comprises a protective cover plate 3, a hollow column rod 31 and a cylindrical mounting inner cylinder 32.

[0039] In Example 2, based on Example 1, to adjust the preload of the bearing at the connection between the swing boom 2 and the swing shaft 21 and the lifting jacquard plate 12: a gas linkage assembly is provided on the cylindrical mounting inner cylinder 32. The gas linkage assembly includes a sealing plate 321, and a miniature air pump 322 is provided on the outer surface of the sealing plate 321. The output end of the miniature air pump 322 extends to the inner side of the cylindrical mounting inner cylinder 32. A preload spring 323 is fixedly connected to the inner surface of the miniature air pump 322, and a piston 324 is fixedly connected to the other end of the preload spring 323. The piston 324 is movably mounted on the inner surface of the cylindrical mounting inner cylinder 32. A bearing preload adjustment assembly is provided at the end of the piston 324 near the sealing plate 321. The bearing preload adjustment assembly includes a first preload plate 3241, a rotating gear 3242, and a second preload plate 3241. 43. The lower end of the pre-tightening plate 3241 is fixedly connected to the outer surface of one end of the piston 324. The inner surface of the pre-tightening plate 3241 and the outer surface of the pre-tightening plate 3243 are movably connected to the surfaces of bearing 1 and bearing 2, respectively. A toothed plate 1 is provided on the inner side of the upper end of the pre-tightening plate 3241. The outer surface of the toothed plate 1 meshes with the outer surface of the rotating gear 3242 and rotates. The rotating gear 3242 is rotatably installed on the inner center of the compensation plate 121. A toothed plate 2 meshes with the outer surface of the rotating gear 3242 and is fixedly installed on the outer surface of the upper end of the pre-tightening plate 3243. Limiting grooves are respectively opened at both ends of the hollow column rod 31 and the cylindrical mounting inner cylinder 32. The inner wall of the limiting groove is movably connected to the outer surface of the pre-tightening plate 3241. A rubber memory sealing block is provided on the inner side of the limiting groove for sealing the limiting groove. In this embodiment, when the bearing preload needs to be adjusted, gas is introduced into the inner side of the cylindrical mounting inner cylinder 32 through the sealing plates 321 at both ends of the cylindrical mounting inner cylinder 32. The micro air pump 322 is activated, allowing gas to enter between the piston 324 and the sealing plates 321. At this time, the piston 324 is continuously pushed inward by the gas, and the preload spring 323 undergoes tensile deformation. As the pistons 324 on both sides move inward, the bearing preload adjustment assembly is triggered. The piston 324 drives the first preload plate 3241 to move horizontally inward. The inner toothed plate 3241 meshes with the surface of the rotating gear 3242, and the outer toothed plate 3243 moves horizontally due to the rotation of the rotating gear 3242. (Refer to...) Figure 11 As shown, at this time, the relative movement of pre-tightening plate 1 3241 and pre-tightening plate 2 3243 pre-tightens the inner bearing 1 and bearing 2. It should be noted that when the miniature air pump 322 and the bearing preload adjustment assembly are not triggered, bearing one and bearing two achieve preload on the bearing side through the elastic compression of the preload spring 323. This avoids the bearing preload adjustment when the preload spring 323 loses its elasticity after long-term use. It is worth noting that during the relative movement of preload plate one 3241 and preload plate two 3243, they are respectively assisted in limiting the movement through the limiting groove and the compensation plate 121. The reason for setting the rubber memory sealing block inside the limiting groove is to block the limiting groove and prevent gas from escaping from the limiting groove, thereby achieving an auxiliary sealing effect for the gas.

[0040] In Example 3, based on Example 2, to achieve auxiliary lubrication at the connection between the swing boom 2, the boom swing shaft 21, and the hollow column rod 31: an annular groove 320 is provided on the outer ring surface of the cylindrical mounting inner cylinder 32, and a lubrication filling component is provided on the inner side of the annular groove 320. The lubrication filling component includes an annular sleeve 34, the cross-section of the annular sleeve 34 is in the shape of an "I" shape, a reserved groove 1 is uniformly provided on the inner wall of the annular surface of the annular sleeve 34, and a reserved groove 2 is provided on the inner wall of the outer ring of the cylindrical mounting inner cylinder 32. The reserved groove 1 and the reserved groove 2 correspond to each other; a filling cavity is formed between the outer side of the annular sleeve 34 and the inner side of the hollow column rod 31, and a sponge ring 342 is provided on the inner side of the filling cavity. One end of the annular sleeve 34 is connected to a filling pipe 341, which penetrates the inner wall of the cylindrical mounting inner cylinder 32 and extends to the outside of the cylindrical mounting inner cylinder 32. A rubber seal is provided at the input port of the filling pipe 341. In this embodiment, an annular sleeve 34 is installed on the inner wall of the annular groove 320. A sponge ring 342 is sleeved inside the filling cavity formed between the annular sleeve 34 and the hollow column rod 31. The combination of the annular sleeve 34 and the sponge ring 342 achieves compensation filling at the annular groove 320. When it is necessary to add lubricating oil to the filling cavity, the lubricating oil is injected into the rubber seal at the input end of the filling pipe 341 using an injection needle tool. The oil enters the filling cavity. At this time, the sponge ring 342 can serve as a temporary storage component for the lubricating oil.

[0041] In Example 4, based on Example 3, in order to trigger the auxiliary extrusion component during the movement of the piston 324 and achieve the auxiliary extrusion of lubricating oil: the inner ring surface of the cylindrical mounting inner cylinder 32 is provided with an inner circumferential groove 3200, and an auxiliary extrusion assembly is provided inside the inner circumferential groove 3200. The auxiliary extrusion assembly includes a deformation bladder ring 35, and the two ends of the deformation bladder ring 35 are respectively in movable contact with the outer surface of the piston 324; an extrusion protrusion 351 is fixedly connected to the outer ring surface of the deformation bladder ring 35. The extrusion protrusion 351 is provided in multiple sets and arranged in a circular array about the horizontal central axis of the cylindrical mounting inner cylinder 32. The extrusion protrusion 351 corresponds one-to-one with the reserved groove 1 and the reserved groove 2. The outer surface of the extrusion protrusion 351 is in movable contact with the inner ring surface of the sponge ring 342. In this embodiment, when the piston 324 is pushed by the gas at both ends, the piston 324 pushes the both ends of the deformation capsule ring 35, at this time, the deformation capsule ring 35 is deformed by the external force, the extrusion block 351 is matched with the reserved groove one and the reserved groove two, the extrusion block 351 is extruded from the communicated reserved groove to the sponge ring 342, at this time, the saturated lubricating oil is seeped out from the penetration hole 310, the bearing pre-tightening is realized through the gas linkage assembly, and at the same time, the auxiliary lubrication at the connecting position is realized.

[0042] In example five, on the basis of example four, in order to realize the auxiliary guide of the lubricating oil seeped out from the penetration hole 310, and further realize the distribution of the lubricating oil to the connecting position, the protective cover plate 3 is fixedly installed on the outer surface of the lifting jacquard plate 12 through bolts, the inner side of the hollow column rod 31 is rotatably connected with the inner wall of both ends of the arm swing shaft 21 through bearing one, the outer surface of both ends of the arm swing shaft 21 is rotatably connected with the inner wall of the lifting jacquard plate 12 through bearing two, the cylindrical installation inner cylinder 32 is fixedly installed on the inner side of the hollow column rod 31, the protective cover plate 3, the hollow column rod 31 and the cylindrical installation inner cylinder 32 are coaxially distributed; the both ends of the hollow column rod 31 are fixedly connected with the inner wall of the protective cover plate 3, the central inner wall of the hollow column rod 31 is provided with the penetration hole 310, the inner side surface of the arm swing shaft 21 is provided with the reserved ring cavity, the inner wall of the reserved ring cavity is communicated with the penetration hole 310, the inner wall of the reserved ring cavity is provided with the threaded groove 210, and the both ends of the reserved ring cavity are respectively provided with the through circular hole 2100; the outer side of the protective cover plate 3 is provided with an auxiliary heat dissipation assembly, the auxiliary heat dissipation assembly comprises an annular air baffle 33 and a connecting air pipe 331, the inner side surface of the annular air baffle 33 is clamped and installed with the inner wall of the protective cover plate 3, the inner side ring surface of the annular air baffle 33 is sealingly connected with one end of the connecting air pipe 331, and the other end of the connecting air pipe 331 away from the annular air baffle 33 is penetratingly connected with the inner wall of the sealing plate 321; In this embodiment, as shown in Figure 8 and Figure 11 the arm swing shaft 21 is fixedly connected with one end of the swing arm 2, when the swing arm 2 is driven to move by the gear piece, the arm swing shaft 21 is movably connected with the outer side of the hollow column rod 31 through the bearing one, when the lubricating oil is seeped out from the penetration hole 310, it enters the reserved ring cavity between the hollow column rod 31 and the arm swing shaft 21, and finally enters the inner side of the bearing two through the through circular hole 2100, the threaded groove 210 is arranged on the inner side of the reserved ring cavity, in order to guide the lubricating oil, and ensure that the lubricating oil is uniformly distributed on the reserved ring cavity and the outer ring surface of the hollow column rod 31 in the process of high-speed rotation, so that the activity between the bearing one and the hollow column rod 31 is smooth, the movement wear of the bearing one and the bearing two is respectively reduced, and the bearing overheating damage can be avoided at the same time; It should also be noted that an auxiliary heat dissipation component is connected to the outside of the protective cover plate 3. Specifically, multiple sets of connecting air ducts 331 pass through the interior of the sealing plate 321 to divert the gas. At this time, the gas enters the inner side of the annular air plate 33 and blows towards both sides of the swing arm 2 and the swing shaft 21. This not only provides auxiliary heat dissipation at the connection, but also achieves auxiliary cooling by forming an oil film on the bearing surface, further reducing the wear and heat at the connection between the swing arm 2 and the swing shaft 21 and the lifting jacquard plate 12.

[0043] Example 6: Based on Example 5, the present invention further proposes a method for using a drive device for a large-scale vertical shaftless jacquard machine, comprising the following steps: Step 1: Gas linkage component triggers bearing preload adjustment: By introducing gas into both ends of the cylindrical mounting inner cylinder 32, the gas enters between the piston 324 and the sealing plate 321 via the micro air pump 322, pushing the piston 324 to move inward. During the movement of the piston 324, the preload plate 1 3241 moves horizontally, causing the toothed plate 1 to mesh with the rotating gear 3242, which in turn causes the toothed plate 2 on the preload plate 2 3243 to move relative to each other, thus preloading bearing 1 and bearing 2. Step 2: Install the lubrication filling component and inject lubricating oil: Install an annular sleeve 34 with an "I" shape on the inner wall of the annular groove 320 to form a filling cavity. Use an injection needle to inject lubricating oil into the input end of the filling pipe 341 through the rubber seal. The oil will be temporarily stored in the sponge ring 342 in the filling cavity to prepare for the subsequent lubrication process. Step 3: Gas linkage component synchronously achieves auxiliary lubrication: When the piston 324 is pushed by gas, it will squeeze the deformation ring 35 of the auxiliary compression component, causing the deformation ring 35 to deform and apply pressure to the sponge ring 342 through the reserved groove. The lubricating oil in the saturated state seeps out from here, enters the reserved ring cavity between the hollow column rod 31 and the boom swing shaft 21 through the permeation hole 310, and then is distributed to the inner side of the bearing through the flow round hole 2100, thereby achieving automatic lubrication and reducing friction between components; Step 4: Setting up auxiliary heat dissipation components to reduce temperature: An auxiliary heat dissipation component, annular air plate 33 and connecting air duct 331, is set on the outside of the protective cover plate 3. Multiple sets of connecting air ducts 331 penetrate the interior of the sealing plate 321 to divert the gas. After the gas enters the annular air plate 33, it blows towards the swing arm 2 and both sides of the swing arm shaft 21. This not only helps to dissipate heat, but also helps to form an oil film, further reducing wear and heat at the connection and ensuring the normal operation of the jacquard machine.
