The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.
[0023] As Figures 1 to 4 shown, a non-woven fabric stenter setting device of the present utility model includes:
[0024] A mounting base 1 and a connection assembly. Transmission shafts 2 are respectively arranged in two groups of shaft holes of the mounting base 1. Two coaxially arranged transmission shafts 2 are symmetrically arranged at both ends of the stenter roll 3. Two groups of mounting members 4 are symmetrically arranged on the mounting base 1. The mounting members 4 are arranged corresponding to the stenter roll 3. A moving member 5 is arranged inside the mounting member 4. A threaded rod 6 is arranged on the moving member 5. The threaded rod 6 is arranged inside the threaded hole of the mounting member 4. A support shaft 7 is arranged in the shaft hole of the threaded rod 6. Two groups of support shafts 7 are symmetrically and coaxially arranged at both ends of the clamping roll 8. Sponge layers are arranged on the outer walls of the stenter roll 3 and the clamping roll 8. The connection assembly is arranged on the mounting base 1 and is connected to the transmission shaft 2 and the support shaft 7. The connection assembly is used for controlling the rotational resistance of the stenter roll 3 and the clamping roll 8:
[0025] A transfer assembly is arranged on the mounting base 1 and is used for stably transporting the non-woven fabric after stenting; by the connection assembly, the rotational resistance of the stenter roll 3 and the clamping roll 8 is increased. This design controls the stenting strength of the non-woven fabric. By precisely controlling the rotational resistance of the stenter roll 3 and the clamping roll 8, the tension of the non-woven fabric during the stenting process is ensured to be uniform, thereby improving the forming quality and production efficiency of the non-woven fabric. The design of the transfer assembly ensures the stable transportation of the non-woven fabric after stenting, avoids material damage caused by uneven tension or unstable transportation, and improves the finished product rate. The combined design of the moving member 5 and the threaded rod 6 makes it simple and fast to adjust the distance between the stenter roll 3 and the clamping roll 8, reduces the adjustment time and labor cost, and has convenient tension adjustment, improving the production efficiency.
[0026] As Figures 1 to 4As shown, as a preferred solution, the connecting component includes two groups of auxiliary members 9 provided at both ends of the mounting base 1. A flow guide member 10 is provided inside the auxiliary member 9. Two groups of limiting members 11 are symmetrically provided on the flow guide member 10. The two groups of limiting members 11 are respectively in contact connection with the transmission shaft 2 and the support shaft 7. An adjusting component is provided on the two groups of limiting members 11. The adjusting component includes a connecting column 12 provided on one group of limiting members 11 and a connecting pipe 13 provided on the other group of limiting members 11. The connecting column 12 is arranged inside the inner cavity of the connecting pipe 13. A nut 14 is provided on the external thread of the connecting pipe 13. A spring 15 is provided on the nut 14. The other end of the spring 15 is connected to the limiting member 11 provided with the connecting column 12. A damping pad 16 is provided at the contact end of the limiting member 11 with the transmission shaft 2 and the support shaft 7; through the adjusting component (the connecting column 12, the connecting pipe 13, the nut 14 and the spring 15), the relative rotational resistance between the stenter roll 3 and the clamping roll 8 can be finely adjusted, ensuring uniform tension of the non-woven fabric during the stenter process, improving the forming quality and dimensional stability of the non-woven fabric. By screwing the nut 14 to compress or release the spring 15, the pressure of the limiting member 11 on the transmission shaft 2 and the support shaft 7 can be changed, realizing rapid adjustment of the stenter tension, reducing the downtime for adjustment, and improving production efficiency. The damping pad 16 provided at the contact end of the limiting member 11 with the transmission shaft 2 and the support shaft 7 can effectively absorb vibration, reduce mechanical wear, extend the service life of the equipment, and at the same time reduce the running noise. The movement trajectory of the limiting member 11 is limited by the cooperation of the auxiliary member 9 and the flow guide member 10.
[0027] As Figures 1 to 4 shown, as a preferred solution, a fixing member 17 is provided on the mounting base 1. A driving motor 18 is provided on the fixing member 17. The output end of the driving motor 18 is coaxially arranged on one group of transmission shafts 2. The driving motor 18 is located on the stenter roll 3 on one side of the transfer component; the output end of the driving motor 18 is directly coaxially arranged on one group of transmission shafts 2. This direct drive design reduces the energy loss during the power transmission process and improves the transmission efficiency. The driving motor 18 is arranged on the fixing member 17 on the mounting base 1 and near the stenter roll 3 on one side of the transfer component. This layout not only saves space but also simplifies the power transmission path. The driving motor 18 provides the stenter power for the non-woven fabric.
[0028] As Figures 1 to 4As shown, as a preferred solution, the transfer assembly includes two sets of support rollers 19 disposed in the positioning holes of the mounting base 1. A conveyor belt 20 is rotatably disposed on the two sets of support rollers 19. A power motor 21 is disposed on the mounting base 1. The output end of the power motor 21 is coaxially connected to one set of support rollers 19. An operating table 22 is disposed on the mounting base 1. The conveyor belt 20 is in contact connection with the operating table 22. The direct coaxial connection of the power motor 21 to the support rollers 19 ensures the stability of the operation of the conveyor belt 20 and the precise control of the speed, which helps to keep the non-woven fabric from being affected by additional tension changes during the conveying process after tenter frame stretching, avoiding material damage. By disposing the two sets of support rollers 19 in the positioning holes of the mounting base 1, a simple and efficient transmission system is formed with the conveyor belt 20, which not only saves space but also simplifies the equipment maintenance and adjustment process. The contact connection between the operating table 22 and the conveyor belt 20 provides stable support for the conveyor belt 20.
[0029] As Figures 1 to 4 shown, as a preferred solution, a heating mechanism 23 and a cooling mechanism 24 are sequentially disposed at the top end of the mounting base 1. The heating mechanism 23 and the cooling mechanism 24 are located above the conveyor belt 20. The non-woven fabric is fixed in shape at high temperature through the heating assembly to enhance its dimensional stability. After the non-woven fabric is heated, it is quickly cooled to fix its form and avoid deformation.
[0030] As Figures 1 to 4 shown, as a preferred solution, multiple sets of support feet 25 are disposed at the bottom end of the mounting base 1. The design of the multiple sets of support feet 25 provides a solid ground contact area and at the same time facilitates the leveling of the device, increasing stability.
[0031] As Figures 1 to 4 shown, as a preferred solution, an adjusting wheel 26 is coaxially disposed on the threaded rod 6. The design of the adjusting wheel 26 enables the operator to intuitively adjust the distance between the tenter frame roller 3 and the clamping roller 8, improving the convenience and efficiency of the operation.
[0032] As Figures 1 to 4 shown, as a preferred solution, its working process is as follows:
[0033] The non-woven fabric raw material is fed into the equipment, ready for stenter setting. The drive motor 18 drives a set of transmission shafts 2 directly to drive the stenter rolls 3 to rotate, starting the stenter setting process. The rotational resistance between the stenter rolls 3 and the clamping rolls 8 is controlled by a connecting component to ensure uniform tension of the non-woven fabric during the stenter setting process. The rotation of the stenter rolls 3, in cooperation with the clamping rolls 8, appropriately stretches the non-woven fabric at the middle position between the two sets of stenter rolls 3. The stenter-set non-woven fabric is stably conveyed by the support roller 19 and the conveyor belt 20 of the transfer component. The power motor 21 controls the speed of the conveyor belt 20 to ensure the smoothness of the non-woven fabric during transportation. The non-woven fabric passes through the heating mechanism 23 and is subjected to high temperature to help fix its shape and enhance its dimensional stability. Subsequently, the non-woven fabric immediately passes through the cooling mechanism 24 and is quickly cooled to fix its form and avoid deformation.
[0034] For a non-woven fabric stenter setting device of the present utility model, its installation method, connection method or setting method are all common mechanical methods, and any implementation that can achieve its beneficial effects can be carried out.
[0035] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
