[0002] Jacquard machines have been widely used in the textile industry. People's expectations for textile colors, large flower patterns, and high-quality fabrics are getting higher and higher. To date, most home textile manufacturing companies still use traditional mechanical jacquards, electronic multi-arm jacquards, rapier and shuttle jacquards, which generally have low productivity and are difficult to meet people's demand for weaving large flower patterns and high-quality home textile products. The shaftless jacquard machine is a device that replaces the vertical shaft with a sprocket drive component.

[0003] At present, most home textile manufacturing companies are in urgent need of equipment transformation of traditional home textile manufacturing industries. Due to the high prices and high maintenance costs of similar foreign products, the design of the opening mechanism of domestic electronic jacquard machines is difficult to compare with similar foreign products in terms of reliability and stability. The load force of the inner and outer knife lifting frames in the jacquard machine equipment currently on the market is relatively large, resulting in uneven impact force of the inner and outer knife lifting frames during the reciprocating lifting motion, making it difficult to maintain balanced lifting.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 In this embodiment, a large-scale jacquard machine balancing mechanism without vertical shaft support includes a jacquard machine body 1, a fan frame 2 and two sets of inner and outer knife lifting frames 5. Two pillars 3 are fixed on the left and right ends of the jacquard machine body 1 on the side opposite to the fan frame 2. A lifting component 4 for driving the two inner and outer knife lifting frames 5 to rise and fall is provided between the front and rear pillars 3. The two lifting components 4 are respectively fixed on the left and right sides of the top of the jacquard machine body 1, and a balancing structure 6 is provided on the opposite side of the two lifting components 4.

[0021] See also Figure 2-3 The balancing structure 6 in this embodiment includes a vertical plate 61 fixed on a side opposite to the two lifting components 4, three support rods 62 are slidably connected to the inner cavity of the vertical plate 61, a pressure plate 63 is fixed to the lower ends of the three support rods 62, a slide bar 64 is fixed to the lower end of the pressure plate 63, a first resistance spring 65 is sleeved on the outer surface of the slide bar 64, and a vertical column 66 is slidably connected to the outer surface of the slide bar 64. The balancing structure 6 also includes resistance components arranged on the front and rear sides of the lower end of the pressure plate 63.

[0022] Among them, three circular holes are opened at the top of the vertical plate 61, and the support rods 62 pass through the circular holes to the inside of the vertical plate 61 and are slidably connected with it, so that the support rods 62 can move into or out of the inside of the vertical plate 61 through the circular holes, so that the three support rods 62 in the same group can drive the pressure plate 63 to move in the inner cavity of the vertical plate 61, and the three support rods 62 can be prevented from falling off from the inside of the vertical plate 61 by passing through the pressure plate 63.

[0023] Moreover, the vertical column 66 is fixed to the bottom of the inner cavity of the vertical plate 61, and a slot is opened at the top of the vertical column 66. The sliding rod 64 passes through the interior of the slot and is slidably connected thereto, so that the sliding rod 64 can move into the interior of the vertical column 66 through the slot, so that the pressure plate 63 can abut against the vertical column 66, and the pressure plate 63 and the vertical column 66 can squeeze the first resistance spring 65.

[0024] At the same time, the top ends of the three support rods 62 are fixed to the lower end of the fan frame 2, and the vertical plate 61 is fixed between the two inner and outer knife lifting lifting frames 5, so that when the lifting assembly 4 drives the vertical plate 61 to move, the vertical plate 61 can drive the two inner and outer knife lifting lifting frames 5 in the same group to perform reciprocating lifting and lowering movements, and at the same time, the load force of the inner and outer knife lifting lifting frames 5 can also be reduced.

[0025] See also Figure 3The resistance assembly in this embodiment includes two hinged rods 67 hingedly connected to the lower end of the pressure plate 63 and the bottom of the inner side of the vertical plate 61. The opposite ends of the front and rear sets of hinged rods 67 are hingedly connected to push blocks 68. The upper and lower ends of the push blocks 68 are fixed with pressure blocks 69. The outer surface of the pressure block 69 is slidably connected to an I-shaped rod 610, and the outer surface of the I-shaped rod 610 is sleeved with a second resistance spring 611.

[0026] Secondly, the opposite ends of the front and rear groups of I-shaped rods 610 are respectively fixed to the front and rear walls of the inner cavity of the vertical plate 61, so that the two groups of I-shaped rods 610 can be fixed inside the vertical plate 61, so that the upper and lower I-shaped rods 610 of the same group can support the pressure block 69 and the second resistance spring 611, and at the same time, the upper and lower I-shaped rods 610 of the same group can support the push block 68 through the upper and lower pressure blocks 69, so that when the upper and lower hinged rods 67 of the same group are squeezed, the two hinged rods 67 of the same group gradually move to an inclined state, so that the two hinged rods 67 of the same group can push the push block 68 to move stably in the inner cavity of the vertical plate 61.

[0027] In addition, sliding holes are provided at opposite ends of the front and rear groups of pressure blocks 69, and the pressure blocks 69 are slidably connected to the inner sides of the sliding holes, so that the pressure blocks 69 can slide on the outer surface of the I-shaped rod 610, so that the pressure blocks 69 can squeeze the second resistance spring 611.

[0028] It should be noted that the lifting assembly 4 and the electronic components mentioned in the text are well known to the public in the prior art, so their working principles will not be described in detail in the text.

[0029] The working principle of the above embodiment is:

[0030] When in use, when the lifting assembly 4 drives the inner and outer knife lifting frame 5 to move up and down through the vertical plate 61, the three support rods 62 of the same group can gradually move into the interior of the vertical plate 61, so that the three support rods 62 can drive the pressure plate 63 to move, and the slide bar 64 can gradually move into the interior of the vertical column 66, so that the pressure plate 63 abuts against the vertical column 66, that is, the pressure plate 63 and the vertical column 66 cooperate to squeeze the first resistance spring 65, thereby reducing the load of the inner and outer knife lifting frame 5 to move up and down, and reducing the reciprocating lifting and lowering motion. The impact force of uneven load can realize dynamic balanced lifting and lowering, enhance the mechanical operation performance and reliable use. At the same time, the pressure plate 63 can squeeze the upper and lower groups of hinged rods 67, so that the front and rear groups of hinged rods 67 can push the front and rear push blocks 68 to move away from each other. When the front and rear push blocks 68 move away from each other, the front and rear groups of pressure blocks 69 can be pushed to slide on the outer surfaces of the two groups of I-shaped rods 610, so that the pressure blocks 69 can squeeze the second resistance spring 611, which can further reduce the load of the reciprocating movement of the inner and outer knife lifting frame 5.
