Description

Technical Field

[0001] The utility model relates to the technical field of looms, in particular to a novel cloth pressing roller for looms. Background Art

[0002] A textile machine, also known as a spinning machine, loom, or cotton spinning machine, is the full name for the tool that processes raw materials such as thread, silk, and linen into yarn and then weaves it into fabric. The cloth roller is a very common mechanism on textile machines. It typically consists of a perforated cloth roller and a pressing roller located next to it. The pressing roller presses the cloth against the cloth roller, increasing friction between the roller and the cloth, and keeping the cloth as taut as possible, facilitating collection.

[0003] Please refer to a loom cloth pressing roller with announcement number CN211546814U. In this patent, it is proposed that "the cloth pressing roller for looms in the prior art is easy to slip during the winding process of the loom, and when the cloth on the loom is wound from top to bottom, the cloth will tend to shrink toward the middle on both sides due to the loss of the side supports on both sides, causing the cloth edges on both sides to relax, the cloth edges on both sides of the rolled cloth roller to be uneven, the cloth to be loose, and the diameter of the cloth winding roller to be uneven, resulting in uncoordinated warp feeding and winding, making it unsuitable for winding." This patent provides threads with different rotation directions on both sides of the cloth pressing roller, which can effectively press the cloth edges on both sides and evenly guide them to both sides of the cloth winding roller, so that the cloth on the lower side of the cloth winding roller is uniform and compact. At the same time, the cross-section of the cloth pressing roller body is a semicircular structure, which can be suitable for different fabrics.

[0004] Although the above patent can prevent the cloth from slipping and make the winding uniform, during the process of winding thin fabrics, the threaded grooves provided on the cloth pressing roller will cause wrinkles in the thin fabric at the threaded grooves, making it difficult to ensure that the fabric rolled on the cloth rolling roller is uniform and compact. Its practical effect is not good and it has certain limitations when used. In view of this, the present application proposes a new type of loom cloth pressing roller. Utility Model Content

[0029] Among them, the driving component also includes two gear shafts 18 that are rotatably connected to the inside of the protective frame 14, and the two gear shafts 18 are meshed with each other. The outer side of the gear shaft 18 is fixedly connected to the second sprocket 17, and the outer sides of the first sprocket 16 and the second sprocket 17 are equipped with a chain 19, which facilitates the use of gear transmission to make the two second sprockets 17 rotate synchronously in opposite directions, and cooperates with the chain transmission structure to make the transmission roller groups 7 on the left and right sides rotate synchronously in opposite directions.

[0030] The beneficial effects of the above embodiment are:

[0031] The new loom cloth pressing roller can effectively guide the edges of the cloth in contact with the cloth pressing transmission belts 8 to the two sides of the cloth winding roller 2 through the reverse rotation of the two cloth pressing transmission belts 8, thereby keeping the cloth wound on the cloth winding roller 2 uniform and compact, so as to effectively improve the weaving efficiency and enhance the practicality of the device; in this process, the cloth pressing transmission belt 8 is in surface contact with the cloth, which can prevent the cloth from contacting and sinking and wrinkling, thereby further enhancing the practical effect of the device.

[0032] The working principle of the above embodiment is:

[0033] The new loom cloth pressing roller first needs to operate the micro motor 11 to drive the threaded rod 12 to rotate, so that the moving block 5 can move up and down inside the rotating block 4 as the threaded rod 12 rotates. After the moving block 5 drives the cloth pressing roller outer frame 6 to move toward the side away from the cloth winding roller 2, the rotation of the cloth pressing roller outer frame 6 can be adjusted by turning the knob 10, so as to adjust the orientation of the cloth pressing roller outer frame 6 and the cloth pressing transmission belt 8 according to the type of cloth to be wound. For heavy fabrics, the cloth pressing transmission belt 8 can be made to be close to the cloth on the cloth winding roller 2, and for light fabrics, the cloth pressing roller outer frame 6 can be made to be close to the cloth on the cloth winding roller 2.

[0034] Then, the rotating shaft 3 can be driven to rotate by an external driving device, so that the cloth winding roller 2 rotates to realize cloth winding. In this process, the gear transmission effect of the two gear shafts 18 can also be used to make the two second sprockets 17 rotate synchronously in the opposite direction. The transmission effect of the chain 19 on the first sprocket 16 and the second sprocket 17 can make the left and right drive roller groups 7 rotate synchronously in the opposite direction as the servo motor 15 runs, thereby effectively guiding the cloth edge contacting the cloth pressing transmission belt 8 to the two sides of the cloth winding roller 2, keeping the cloth wound on the cloth winding roller 2 uniform and compact, thereby effectively improving the weaving efficiency and enhancing the practicality of the device.
