Description

Technical Field

[0001] The utility model relates to the technical field of jacquard machines, in particular to a belt drawing device of the jacquard machine. Background Art

[0002] A jacquard loom is a device used in the textile industry to weave complex patterns. It uses punched cards to control the movement of each thread in the fabric, allowing it to weave fabrics with complex designs. The drawstring mechanism in a jacquard loom is usually part of the loom that controls the position or tension of the warp threads. The drawstring mechanism can have different designs, depending on its purpose and the function it is intended to achieve. For example, in some designs, the drawstrings may consist of a series of chains or ropes connected to the warp threads, and the position of the warp threads can be changed by lifting or loosening these drawstrings.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0023] Combine Figure 1 A belt drawing device of a large jacquard machine includes a support plate 1, and the support plate 1 is fixedly connected to two groups, one side of which is fixedly connected to a motor A2, and the output end of the motor A2 is fixedly connected to a winding roller 21.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1:

[0026] See also Figure 1 、 Figure 4 and Figure 5A fixing assembly 8 for fixing the belt is fixedly connected to one side of the winding roller 21. The fixing assembly 8 includes a fixing plate 81 fixedly connected to one side of the winding roller 21. The lower end of the fixing plate 81 is fixedly connected to a connecting rod 88. The connecting rod 88 is fixedly connected with two groups. One side of the two groups of connecting rods 88 is fixedly connected to a tooth block A87. The lower ends of the two groups of connecting rods 88 are commonly engaged with a clamping block 82. Clamping grooves 85 are provided on both sides of the clamping block 82. One side of the clamping groove 85 is fixedly connected to a spring 86. One side of the spring 86 is fixedly connected to a clamping plate 84. One side of the clamping plate 84 is fixedly connected to a tooth block B83. The tooth block B83 is meshed with the tooth block A87.

[0027] Specifically, the belt is placed between the connecting rod 88 and the block 82, and then the utility tool is used to squeeze the card plate 84 to make the spring 86 contract, thereby pulling the connecting rod 88 downward until the block 82 can clamp and fix the belt, and then the squeezing of the card plate 84 is released. At this time, the spring 86 recovers its deformation, so that the tooth block B83 is engaged and connected with the tooth block A87, which can fix the block 82, thereby fixing the belt and reducing the probability of slipping. Then the operation of the motor A2 can drive the winding roller 21 to rotate to reel the belt.

[0028] Example 2:

[0029] See also Figures 1-4 One side of one group of support plates 1 is fixedly connected to a motor B4, and the output end of the motor B4 is fixedly connected to a reeling roller 41, one side of one group of support plates 1 is fixedly connected to a guide rod 9, and the guide rod 9 is fixedly connected to two groups, one side of which is fixedly connected to a cleaning component fixed connection 6 for cleaning the belt, and the cleaning component fixed connection 6 includes a mounting plate fixed connection 61 fixedly connected to one side of the fixed connection of one group of support plates 1, and the mounting plate fixed connection 61 is fixedly connected to a motor C fixed connection 62 on one side of the fixed connection of the motor C fixed connection 62. The output end of the motor C fixed connection 62 is fixedly connected to a turntable fixed connection 63, and the turntable fixed connection 63 is fixedly connected to a fixed connection on one side. The shaft fixed connection 64 is fixedly connected, the outer surface of the fixed shaft fixed connection 64 is fixedly connected with a snap block fixed connection 67, the lower end of the snap block fixed connection 67 is fixedly connected with a connecting plate fixed connection 65, the lower end of the connecting plate fixed connection 65 is fixedly connected with a brush fixed connection 66, the mounting plate fixed connection 61 is fixedly connected on one side with a limit plate fixed connection 68, the limit plate fixed connection 68 is fixedly connected in two groups, the connecting plate fixed connection 65 is fixedly connected between the two groups of limit plate fixed connections 68, a heating rod 7 is fixedly connected between the two groups of support plates 1, one side of one group of support plates 1 is fixedly connected with a fan 5, and a waste box 3 is slidably connected between the two groups of support plates 1.

[0030] Specifically, the motor B4 drives the unwinding roller 41 to rotate, and the belt is unwound from the unwinding roller 41. The guide rod 9 can guide the moving direction of the belt, and the installation of two groups can prevent the belt from being stretched straight during the movement of the belt, reducing the probability of the belt breaking. The motor C62 drives the turntable 63 to rotate, and the fixed shaft 64 rotates, thereby driving the connecting plate 65 to move horizontally. The brush 66 contacts the belt to clean the dust on the belt. The fan 5 can blow away the dust on the belt, reducing the pollution of the belt. The dust falls into the waste box 3 for recycling. The heating rod 7 can heat the belt to make the belt soft, which is convenient for pulling the belt and reduces the probability of the belt breaking.
