Description

Technical Field

[0001] This utility model belongs to the field of jacquard machine technology, specifically relating to a fabric flattening structure for a computer jacquard machine. Background Technology

[0002] A jacquard machine is a type of machinery used in the textile industry. Its core function is to create complex patterns on the surface of fabric by controlling the rise and fall of warp yarns. It can translate designed patterns into mechanical movements, causing the warp yarns to interweave with the weft yarns according to specific rules, thereby weaving fabrics with exquisite patterns.

[0003] In the prior art, after the jacquard operation of the fabric, it is usually necessary to flatten the fabric. However, the existing flattening structure usually only flattens the fabric, which makes it very easy for indentations or edge wavy patterns to appear on the fabric surface. Therefore, we propose a fabric flattening structure for computer jacquard machines to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a fabric flattening structure for a computerized jacquard machine to solve the problems mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a fabric flattening structure for a computer jacquard machine, including a main component 1, an A flattening component 2 and a B flattening component 3 on the main component 1, and a drive component 4 on the main component 1, and the drive component 4 is connected to the A flattening component 2.

[0026] The main component 1 includes a base 11, which is configured as an L-shaped structure;

[0027] A flattening assembly 2 includes B drive rollers 21, and multiple B drive rollers 21 are provided. All B drive rollers 21 are provided on the base 11. Each B drive roller 21 is provided with a B drive shaft 24, and the multiple B drive shafts 24 penetrate and extend out of the surface of the base 11. Multiple sliding grooves are provided on the surface of the base 11. Multiple B driven rollers 22 are provided above the B drive rollers 21, and the distance between the multiple B driven rollers 22 and the multiple B drive rollers 21 gradually decreases. Each B driven roller 22 is provided with a limiting member 23, and the multiple limiting members 23 are provided in the sliding grooves.

[0028] Specifically, after the jacquard process on the fabric, the fabric can be flattened using the A flattening component 2. Through three sets of B drive rollers 21 and B driven rollers 22, the fabric can be lightly pressed multiple times, avoiding surface indentations or edge wavy lines caused by a single strong press. Since the distance between the B drive rollers 21 and B driven rollers 22 decreases from left to right, the fabric can be placed between the B drive rollers 21 and B driven rollers 22 from the left side, thereby gradually increasing the pressure on the fabric and preventing indentations or edge wavy lines from appearing on the fabric surface.

[0029] In this embodiment, the A flattening assembly 2 further includes a rack 25, a gear 26, a connecting rod 27, and a B motor 28. Multiple racks 25 are provided, and the multiple racks 25 are respectively provided on multiple B driven rollers 22. Multiple gears 26 are provided, and the multiple gears 26 are respectively provided on multiple B transmission rollers 21. The multiple gears 26 mesh with the multiple racks 25. The connecting rod 27 connects the multiple gears 26. The B motor 28 is provided on the B transmission rollers 21, and the output end of the B motor 28 is connected to the end of the connecting rod 27.

[0030] Specifically, in order to synchronously adjust the height of the three B driven rollers 22 according to the different thicknesses of the fabric, a rack 25 can be fixedly installed at the lower end of the B driven roller 22, and a gear 26 can be rotatably installed at the side end of the B drive roller 21 to mesh the rack 25 and the gear 26. Multiple gears 26 are connected through a connecting rod 27. At this time, the B motor 28 can be started to drive the gears 26 to rotate, thereby controlling the three B driven rollers 22 to rise and fall synchronously. During the rising and falling, the limiting member 23 can slide in the sliding groove, so that the B driven rollers 22 can rise and fall stably, thereby adjusting the pressure on the fabric.

[0031] In this embodiment, the drive assembly 4 includes a D motor 41, a B chain 42, a C chain 43, a D chain 44, and a B chain 45. The B chain 42, C chain 43, and D chain 44 are respectively connected to multiple B drive shafts 24. The B chain 45 connects the B chain 42, C chain 43, and D chain 44. The D motor 41 is mounted on the base 11, and the output end of the D motor 41 is connected to the B chain 42.

[0032] Specifically, when flattening the fabric, the D motor 41 can be started to drive the B toothed disc 42 to rotate. The rotation of the B toothed disc 42 drives the B chain 45, which in turn drives the C toothed disc 43 and the D toothed disc 44 to rotate together in the same direction as the B toothed disc 42. At this time, the B toothed disc 42, C toothed disc 43, and D toothed disc 44 can be connected to multiple B drive shafts 24, and then the multiple B drive shafts 24 can be connected to multiple B drive rollers 21. This allows the fabric to move when flattening the fabric. By controlling the distance between the multiple B driven rollers 22 and the B drive rollers 21, the fabric can move between the B drive rollers 21 and the B driven rollers 22, and the flattening operation can be performed simultaneously.

[0033] In this embodiment, the main component 1 also includes an A drive roller 12, an A driven roller 13, an A motor 14, an A chain 15, and an A chain 16. There are two A drive rollers 12 and two A driven rollers 13, and they are symmetrically arranged. Both A drive rollers 12 and A driven rollers 13 are mounted on the base 11. Each of the two A drive rollers 12 is provided with an A drive shaft 17, which penetrates and extends out of the surface of the base 11. There are two A chain 15s, and each A chain 15 is connected to one of the two A drive shafts 17. The A chain 16 connects the two A chain 15s. The A motor 14 is mounted on the base 11, and its output end is connected to the A chain 15.

[0034] Specifically, in order to guide the fabric, two A drive rollers 12 and A driven rollers 13 are provided on the main component 1. When flattening the fabric, the fabric can be placed between the left A drive rollers 12 and A driven rollers 13, and then passed between multiple B drive rollers 21 and B driven rollers 22 to complete the flattening operation of the high-density jacquard area. When flattening the low-density jacquard area, the fabric can be passed between the left A drive rollers 12 and A driven rollers 13, and then passed between the right A drive rollers 12 and A driven rollers 13, and then passed through the B flattening component 3 to complete the flattening operation. In use, an A drive shaft 17 is set on the two A drive rollers 12, and an A toothed disc 15 is set on the A drive shaft 17. The two A toothed discs 15 are connected by an A chain 16. At this time, by starting the A motor 14, the two A toothed discs 15 can be driven to rotate, thereby guiding the fabric.

[0035] In this embodiment, the flattening assembly 3 includes a C drive roller 31, a C driven roller 32, a C motor 33, and a C drive shaft 34. The C drive roller 31 and the C driven roller 32 are both mounted on the base 11. The C drive shaft 34 is mounted on the C drive roller 31 and extends through and out of the surface of the base 11. The C motor 33 is mounted on the base 11, and the output end of the C motor 33 is connected to the C drive shaft 34.

[0036] Specifically, when flattening the fabric in the low-density jacquard area, the fabric can first be passed between the left-side drive roller 12 and driven roller 13, then between the right-side drive roller 12 and driven roller 13, and then between the C drive roller 31 and driven roller 32 to flatten it. During flattening, a C drive shaft 34 can be set on the C drive roller 31, and the output end of the C motor 33 can be connected to the C drive shaft 34. By starting the C motor 33, the C drive shaft 34 can be rotated, so that the fabric can be flattened while moving.

[0037] In this embodiment, both the C drive roller 31 and the C driven roller 32 are provided with multiple hemispherical structures, and the multiple hemispherical structures are arranged in a circumferential array.

[0038] Specifically, in order to improve the flattening efficiency when flattening the fabric in the low-density jacquard area, multiple hemispherical structures can be set on the surface of C drive roller 31 and C driven roller 32. The multiple hemispherical structures are arranged in a circumferential array. The pressure can be increased through the hemispherical structures, thereby improving the flattening efficiency.

[0039] In this embodiment, multiple spherical grooves are provided on multiple B drive rollers 21 and B driven rollers 22, and the multiple spherical grooves are arranged in a circumferential array.

[0040] Specifically, when flattening the fabric in the high-density jacquard area, in order to avoid indentations or edge wavy patterns on the fabric surface, multiple B drive rollers 21 and B driven rollers 22 can be set, and multiple spherical grooves can be opened on the B drive rollers 21 and B driven rollers 22, thereby reducing the pressure during flattening. Through multiple low-pressure flattening operations, the fabric in the high-density jacquard area can be flattened.

[0041] The working principle and usage process of this utility model are as follows: When flattening the jacquard fabric, the fabric can be placed in flattening component A 2 or flattening component B 3 according to different jacquard densities. When flattening the fabric in the high-density jacquard area, the flattening component A 2 can be driven by the driving component 4. Flattening component A 2 can flatten the fabric in the high-density jacquard area. When flattening the fabric in the low-density jacquard area, flattening component B 3 can be used to quickly flatten the fabric.

[0042] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
