Description

Technical Field

[0001] The utility model relates to a traction and clamping mechanism for straw production, belonging to the technical field of straws. Background Art

[0002] The straw uses the principle of atmospheric pressure. When using it, sucking away some air through the straw will cause the pressure inside the tube to decrease. In order to balance the air pressure, the atmospheric pressure will force the liquid inside the tube to rise. When you stop inhaling, the liquid inside the tube drops and the pressure returns to equilibrium. This is the wonderful principle and application of the straw. After the invention of plastic, paper straws were replaced by colorful plastic straws because plastic is more flexible and beautiful than paper straws.

[0003] During the straw processing, in order to maintain the stability of the straws during the production process and to correctly position the straws, the straws need to be clamped and pulled, so a pulling and clamping mechanism is needed. However, the existing technology may not be convenient for adjusting the clamping force according to the customary diameter while pulling and clamping the straws. Uneven clamping force may cause the straws to be deformed or damaged during the production process, such as bending, twisting or breaking, affecting the appearance and quality of the product. In addition, improper clamping may also cause the straws to be unstable in position during the pulling process, thereby affecting the dimensional accuracy and uniformity of the product.

[0004] Therefore, a traction and clamping mechanism for straw production is proposed. Utility Model Content

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4As shown, the embodiment of the utility model provides a traction clamping mechanism for straw production, including a bottom plate 1, a base 2 is fixedly installed on the top of the bottom plate 1, a through groove 8 is opened on the top of the bottom plate 1, a traction mechanism 3 is arranged in the inner cavity of the base 2, the traction mechanism 3 includes a servo motor 301, a threaded rod 302, a threaded sleeve 303 and a column 304, a clamping mechanism 4 is arranged on the top of the bottom plate 1, the clamping mechanism 4 includes a fixed sleeve 401, a spring 402, a through hole 403, a connecting rod 404, a clamping ring 405, a connecting plate 406 and a handle 407, the servo motor 301 is fixedly installed On the right side of the base plate 1, the threaded rod 302 is fixedly connected to the output end of the servo motor 301, the threaded sleeve 303 is threadedly connected to the surface of the threaded rod 302, the column 304 is fixedly connected to the top of the threaded sleeve 303, the fixed sleeve 401 is fixedly connected to the top of the column 304, the spring 402 is fixedly connected to the inner side of the fixed sleeve 401, the through hole 403 is opened on the left and right sides of the surface of the fixed sleeve 401, the connecting rod 404 is movably connected to the inner side of the through hole 403, the clamping ring 405 is fixedly connected to the inner side of the spring 402, and the connecting rod 404 is connected to the clamping ring 405.

[0027] By setting the traction mechanism 3, the straw can be clamped and driven to move forward at the same time. By setting the clamping mechanism 4, it can adapt to the clamping and traction of straws of different sizes, which can improve the versatility and flexibility of the equipment and adapt to the size of the straw. It can easily switch to produce straws of different specifications without replacing the entire machine.

[0028] Example 2

[0029] In one embodiment, the connecting plate 406 is fixedly connected to the outer side of the connecting rod 404, the handle 407 is fixedly connected to the outer side of the connecting plate 406, guide grooves 5 are opened on the front and rear sides of the inner cavity of the base 2, guide blocks 6 are fixedly installed on the front and rear sides of the surface of the threaded sleeve 303, and the guide blocks 6 are slidably connected in the inner cavity of the guide groove 5, a protective cover 7 is fixedly installed on the right side of the base 2, the servo motor 301 is located on the inner side of the protective cover 7, and mounting bolts 9 are fixedly installed on all sides of the surface of the bottom plate 1, and the lower ends of the mounting bolts 9 penetrate the bottom plate 1 and extend to the bottom of the bottom plate 1.

[0030] The setting of the guide groove 5 and the guide block 6 can play a guiding role to prevent the threaded sleeve 303 from being offset during movement. The setting of the protective cover 7 can protect the servo motor 301 from external collisions that may cause equipment failure. The base plate 1 can be installed and fixed by installing the bolts 9.

[0031] When the utility model is working: by pulling the handle 407 outward, the connecting plate 406 can be driven to move outward, and the connecting plate 406 will drive the connecting rod 404 and the clamping ring 405 to move outward while moving. The clamping ring 405 will squeeze the spring 402 during the movement. At this time, after the straw passes through the clamping ring 405, the hand can release the handle 407. At this time, after the spring 402 loses the squeezing of the external force, it can rebound by its own tension, thereby driving the clamping ring 405 to move inward, clamping and fixing the straw. At this time, the servo motor 301 can be started to work. After the servo motor 301 is started, it will drive the threaded rod 302 at the output end to rotate. During the rotation of the threaded rod 302, the threaded sleeve 303 can be driven to move laterally through the effect of the threaded connection, thereby pulling the straw forward.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
