Description

Technical Field

[0001] The utility model belongs to the technical field related to base cloth production, and specifically relates to a stable tensioning structure for base cloth production. Background Art

[0002] The base cloth has the characteristics of tight texture, thickness, wear resistance, non-pilling and good air permeability. During the base cloth production process, multiple sets of power sources are required to achieve the tensioning of the cloth, which increases its tensioning cost. At the same time, due to the elasticity of the fibers inside the cloth, there is a risk of shrinkage of the base cloth after tensioning, which affects the quality of its tensioning. Application No. CN202322572046.8 discloses a tensioning adjustment structure for base cloth production. The base cloth is heated by setting a heating plate to stretch the fibers inside the base cloth, preventing the base cloth from tearing during the tensioning process, thereby ensuring the quality of its tensioning. The cooling box moves on the base cloth to shape the base cloth. Since the base cloth and the cooling box cannot effectively contact each other during the movement of the cooling box, the heat exchange is limited, and the cooling box cannot effectively achieve full coverage of the base cloth, resulting in uneven heat dissipation. The actual use effect needs to be improved.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0026] Among them, a gearbox 2 is fixedly installed on the outside of the heating support frame 8, and a motor 3 is set on the outside of the gearbox 2. Two motors 3 are arranged above and below the induction heating roller 1 to provide power support for the rotation of the induction heating roller 1.

[0027] Guide roller 1 4 and guide roller 3 6 are symmetrically arranged with respect to guide roller 2 5. The height positions of guide roller 1 4 and guide roller 3 6 are lower than the height position of guide roller 2 5. Guide roller 1 4, guide roller 2 5 and guide roller 3 6 cooperate with each other to keep the base cloth in a tensioned state.

[0028] A gearbox 2 13 is fixedly installed on the outside of the cooling support frame 10, and a motor 2 15 is fixedly installed on the outside of the gearbox 2 13. A driving gear 23 is installed on the main shaft of the motor 2 15. A driven gear 1 24 is meshed with the side of the driving gear 23, and a driven gear 2 25 is meshed above the driven gear 1 24. The motor 2 15 is used to provide power support for the rotation of the cooling roller 7.

[0029] There are two cooling rollers 7 arranged up and down. The cooling rollers 7 are designed as hollow structures. A through hole 26 is provided at the end of the cooling roller 7. The driven gear 1 24 is installed on the cooling roller 7 located below, and the driven gear 2 25 is installed on the cooling roller 7 located above. The rotation directions of the two cooling rollers 7 are opposite.

[0030] A cooling liquid inlet box 14 is provided on the outside of the gearbox 2 13, and a liquid inlet pipe 16 is provided on the outside of the cooling liquid inlet box 14. A cooling liquid outlet box 18 is provided on the side of the cooling support frame 10 away from the gearbox 2 13, and a liquid outlet pipe 17 is provided on the outside of the cooling liquid outlet box 18.

[0031] A control box 27 is provided on the cooling support frame 10 below the second gearbox 13 , and an MCU microcontroller is provided in the control box 27 .

[0032] The working principle of the present invention is as follows: in a normal processing state, the base cloth is in a tensioned state during the conveying process, and an anti-skid pattern that increases friction is provided on the guide roller. The base cloth drives the guide roller to rotate, and the guide roller has a certain angular velocity. After the base cloth is evenly heated by the induction heating roller 1, the base cloth expands due to heat, which will cause the conveying line speeds of the front and rear of the conveying device to be inconsistent. A heat expansion section is formed between the induction heating roller 1 and the cooling roller 7. The base cloth will be in a loose state in the heat expansion section, so the guide roller will slip and will not be able to rotate under the drive of the base cloth. A rotary encoder 20 is installed at a coaxial position on the outer side of the guide roller 5. The rotary encoder 20 can be selected: 1XP8001-1 / 1024. The rotary encoder 20 can detect whether the base cloth is in a tensioned state, and then adjust the position of the guide roller.

[0033] The specific adjustment process is as follows: When the rotary encoder 20 detects that the angular velocity of the guide roller 25 has intermittent changes, or the angular velocity is zero, it means that the guide roller has slipped. The control component in the operation box controls the operation of the lifting hydraulic rod 21. There are two lifting hydraulic rods 21. The hydraulic components supporting the two lifting hydraulic rods 21 are equipped with a diverter and collector valve. The diverter and collector valve controls the amount of oil entering each hydraulic cylinder to ensure that they extend and retract at the same speed and distance, thereby driving the guide bracket 12 to be adjusted up and down. After the rotary encoder 20 is adjusted to a stable angular velocity, the lifting hydraulic rod 21 stops working according to the feedback of the rotary encoder 20.

[0034] The utility model is provided with an induction heating roller 1 to uniformly heat the base cloth as a whole, and utilizes a cooling roller 7 to uniformly cool the base cloth, so as to ensure uniform heat exchange during the hot and cold changes of the base cloth, thereby improving the uniformity of thermal deformation of the base cloth, and thus improving the production quality of the base cloth. Three guide rollers are provided between the induction heating roller 1 and the cooling roller 7, among which the height of the guide roller located in the middle position can be automatically adjusted to ensure that the base cloth is in a tensioned state during the transportation process, avoid inconsistent conveying line speeds of the front and rear conveying devices of the base cloth conveying device, which causes wrinkles in the base cloth, and ensure the stability of the quality of the base cloth production process.
