[0001] The utility model belongs to the technical field of non-alkali glass fiber yarn production, and particularly relates to a tensioning device for non-alkali glass fiber yarn production with automatic feeding. Background Technique

[0002] Non-alkali glass fiber, also known as E glass fiber, refers to glass fiber with low alkali metal oxide content. Glass fiber is an excellent inorganic non-metallic material, usually used as a reinforcing material, electrical insulating material, heat insulating and heat preservation material, etc. in composite materials, and is widely used in various fields of the national economy.

[0003] Referring to a tensioning device for non-alkali glass fiber yarn spinning with the reference publication number of CN216107398U, although this patent can automatically feed non-alkali glass fiber yarn during use, during the process of transporting non-alkali glass fiber yarn spinning, due to the lack of baffle plates at both ends of the roller, the non-alkali glass fiber yarn spinning will deviate during the feeding process, making it inconvenient for people to use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tensioning device for non-alkali glass fiber yarn production with automatic feeding, which has a simple structure and reasonable design, in order to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

Detailed Embodiment

[0018] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] As Figure 1 - Figure 4 shown, a tensioning device for the production of non-alkali fiberglass yarn with automatic feeding includes a bottom plate 1, two brackets 2 installed on the top of the bottom plate 1, and a top plate 3 installed on the tops of the two brackets 2. A tensioning mechanism is installed at the bottom of the top plate 3. The tensioning mechanism includes two telescopic mechanisms installed on the bottom surface of the top plate 3, two fixing plates 5 installed at the bottoms of the two telescopic mechanisms, and a tensioning roller 6 installed between the two fixing plates 5. The telescopic mechanism includes a sleeve 4 installed on the bottom surface of the top plate 3, a spring 18 installed on the inner wall of the top of the sleeve 4, and a telescopic rod 17 sleeved inside the sleeve 4. The bottom of the spring 18 is fixedly connected to one end of the telescopic rod 17, and the bottom end of the telescopic rod 17 extends to the outside of the sleeve 4 and is fixedly connected to the top of the fixing plate 5. Feeding mechanisms are installed inside both of the two brackets 2, and the tensioning mechanism is located between the two feeding mechanisms. The feeding mechanism includes two feeding rollers 7 rotatably connected inside the brackets 2, two baffles 9 sleeved outside the two feeding rollers 7, a rotating mechanism installed outside the feeding rollers 7 for driving the feeding rollers 7 to rotate. The rotating mechanism includes two gears 10 installed outside the two feeding rollers 7 and meshing with each other, and a driving motor 16 installed on one side of the bracket 2 for driving one of the feeding rollers 7 to rotate. A driving mechanism installed on the top of the top plate 3 for driving the two baffles 9 to approach or move away from each other. The driving mechanism includes two connecting plates 12 located on the top of the top plate 3, moving plates 14 installed at both ends of the two connecting plates 12, and a driving component installed on the top of the top plate 3 for driving the two connecting plates 12 to approach or move away from each other. The bottoms of the four moving plates 14 are respectively fixedly connected to the tops of the four baffles 9. The driving component includes two support plates 11 installed on the top of the top plate 3, a threaded rod 13 rotatably connected between the two support plates 11, and two threaded sleeves 15 threadedly connected to the outside of the threaded rod 13. The bottoms of the two threaded sleeves 15 are respectively fixedly connected to the tops of the two connecting plates 12. A rotating motor 8 for driving the threaded rod 13 to rotate is installed on one side of one of the support plates 11.

[0020] It should be noted that for the tensioning device for the production of non-alkali fiberglass yarn with automatic feeding, when in use, the non-alkali fiberglass yarn passes through between two feeding rollers 7, contacts the bottom of the tensioning roller 6 and then passes through between another two feeding rollers 7. Then, the distance between two baffles 9 can be adjusted according to the width of the non-alkali fiberglass yarn for spinning. When the rotating motor 8 rotates, it will drive the threaded rod 13 to rotate. At this time, the two threaded sleeves 15 will move. When the two threaded sleeves 15 move, they will drive the two connecting plates 12 to move. The two connecting plates 12 will move towards the side close to each other, and further drive the two baffles 9 to move towards the side close to each other, thereby reducing the distance between the two baffles 9. When the baffle 9 contacts the non-alkali fiberglass yarn, the rotating motor 8 stops rotating. At this time, the driving motor 16 is started. The driving motor 16 will drive one of its feeding pipes 7 to rotate. Under the meshing of the two gears 10, the two feeding rollers 7 will rotate simultaneously, thereby driving the non-alkali fiberglass yarn to move, and further realizing the automatic feeding operation. When feeding the non-alkali fiberglass yarn, the non-alkali fiberglass yarn will pass through the tensioning roller 6. Since the height of the tensioning roller 6 is lower than that of the feeding mechanism, when the non-alkali fiberglass yarn passes through the bottom of the tensioning roller 6, it will drive the tensioning roller 6 to lift and lower, and further drive the telescopic rod 17 to lift and lower, so that the spring 18 expands and contracts, thus facilitating the continuous tensioning adjustment of the non-alkali fiberglass yarn.

[0021] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
