Description

Technical Field

[0001] The present invention belongs to the technical field of multi-layer composite carpet processing, and particularly relates to a drying and winding device for processing multi-layer composite carpets. Background Art

[0002] In the production process of multi-layer composite carpets, drying and winding are crucial steps. Traditional drying devices often adopt a single hot air drying method, which cannot accurately dry each layer of carpets with a multi-layer composite structure, resulting in low drying efficiency and easy to affect the carpet quality due to local overheating or insufficient drying. In terms of winding, manual operation or simple mechanical winding is difficult to ensure the uniformity of the tension of the carpet during the winding process, and problems such as wrinkles and stretching deformation are likely to occur.

[0003] Therefore, in view of the above problems, further improvements are made. Summary of the Invention

[0004] The main purpose of the present invention is to provide a drying and winding device for processing multi-layer composite carpets, which is linked by a drying module, a winding module and a control module to solve the problems of low drying efficiency, poor winding quality and insufficient automation in the prior art.

[0005] To achieve the above object, the present invention provides a drying and winding device for processing multi-layer composite carpets, including a drying module, a winding module and a control module, wherein:

[0006] The drying module includes a top layer air outlet unit, a bottom layer air outlet unit, an intermediate layer air outlet unit and an infrared heating unit, wherein:

[0007] During drying, the infrared heating unit is started through the control module, and the multi-layer composite carpet is first infrared heated by infrared heating elements, so that the moisture inside the surface layer of the multi-layer composite carpet is vaporized;

[0008] Then, the top layer air outlet unit, the bottom layer air outlet unit and the intermediate layer air outlet unit are simultaneously started through the control module. The top layer air outlet unit dries the top layer of the multi-layer composite carpet with the first hot air at a first angle (preferably blown in at 45 degrees), and takes away the vaporized moisture while hot drying; the bottom layer air outlet unit dries the bottom layer of the multi-layer composite carpet with the second hot air at a second angle (preferably blown in at 45 degrees); the intermediate layer air outlet unit dries the intermediate layer of the multi-layer composite carpet with the third hot air at a third angle (preferably blown vertically) (accurately drying each layer of the multi-layer composite carpet through a multi-layer air outlet channel);

[0009] The winding module includes a tension control unit and a winding deviation correction unit. The tension control unit real-time detects the winding diameter and tension data of the multi-layer composite carpet during the winding process, and transmits the obtained winding diameter and tension data to the control module. The control module analyzes and controls the winding motor to make the winding motor output a winding speed suitable for the current winding situation, so as to perform dynamic adjustment according to the winding situation (different winding diameters generate different tensions, so it is necessary to adjust the winding speed to ensure that the carpet always maintains a uniform tension); the winding deviation correction unit real-time detects the edge position of the multi-layer composite carpet on the winding roller through a camera during the winding process, and transmits the position data to the control module to determine whether the edge position is within the appropriate range of the winding roller. If it is detected that the edge position deviates from the preset distance, the control module drives the winding roller to perform position adjustment, so that the multi-layer composite carpet returns to the correct winding path, ensuring that the edge of the wound carpet is neat.

[0010] As a further preferred technical solution of the above technical solution, for the first hot air of the top air outlet unit, the temperature is 60°C, the wind speed is 5m / s, and the circulation frequency is 10 times per minute, quickly drying the top layer of the multi-layer composite carpet (generally the wool fiber surface layer) and taking away the vaporized moisture;

[0011] For the second hot air of the middle air outlet unit, the temperature is 80°C, and the hot air is evenly distributed through the porous air duct, the wind speed is 3m / s, and the circulation frequency is 8 times per minute, deeply drying the middle layer of the multi-layer composite carpet (generally the chemical fiber middle layer);

[0012] For the third hot air of the bottom air outlet unit, the temperature is 70°C, the wind speed is 4m / s, and the circulation frequency is 9 times per minute, ensuring that the bottom layer of the multi-layer composite carpet (generally the rubber composite bottom layer) is fully dried.

[0013] As a further preferred technical solution of the above technical solution, waste heat recovery units are provided at the air outlets of the top air outlet unit, the bottom air outlet unit, and the middle air outlet unit. The heat in the discharged high-temperature hot air is recovered through a heat exchanger, and the recovered heat is used to preheat the fresh air entering the drying module, so that the fresh air is preheated before entering each air outlet unit through heat exchange (reducing the energy consumption of the hot air system).

[0014] As a further preferred technical solution of the above technical solution, the drying module further includes a humidity detection unit. The humidity detection unit respectively detects the humidity of the top layer, the middle layer, and the bottom layer of the multi-layer composite carpet and transmits the obtained humidity data to the control module. The control module determines whether the humidity of the top layer, the middle layer, and the bottom layer of the multi-layer composite carpet reaches the corresponding drying standard. If it reaches, the corresponding air outlet unit is closed, otherwise, continue drying.

[0015] As a further preferred technical solution of the above technical solution, when the control unit detects that the winding diameter of the multi-layer composite carpet reaches the threshold value, it controls the winding motor to stop driving the winding roller.

[0019] Preferred embodiment.

[0020] As Figure 1 shown, the present invention discloses a drying and winding device for processing multi-layer composite carpets, including a drying module, a winding module, and a control module, wherein:

[0021] The drying module includes a top air outlet unit, a bottom air outlet unit, a middle layer air outlet unit, and an infrared heating unit, wherein:

[0022] During drying, the infrared heating unit is started through the control module, and the multi-layer composite carpet is first subjected to infrared heating by infrared heating elements, so that the moisture inside the surface layer of the multi-layer composite carpet is vaporized;

[0023] Then, the top air outlet unit, the bottom air outlet unit, and the middle layer air outlet unit are simultaneously started through the control module. The top air outlet unit dries the top layer of the multi-layer composite carpet with the first hot air at the first angle (preferably blown in at 45 degrees), and takes away the vaporized moisture while hot drying; the bottom air outlet unit dries the bottom layer of the multi-layer composite carpet with the second hot air at the second angle (preferably blown in at 45 degrees); the middle layer air outlet unit dries the middle layer of the multi-layer composite carpet with the third hot air at the third angle (preferably blown vertically) (precise drying of each layer of the multi-layer composite carpet through a multi-layer air outlet channel);

[0024] The rewinding module includes a tension control unit and a rewinding deviation rectification unit. The tension control unit real-time detects the rewinding diameter and tension data of the multi-layer composite carpet during the rewinding process, and transmits the obtained rewinding diameter and tension data to the control module. The control module analyzes and controls the rewinding motor to enable the rewinding motor to output a rewinding speed suitable for the current rewinding situation, so as to perform dynamic adjustment according to the rewinding situation (different rewinding diameters generate different tensions, so it is necessary to adjust the rewinding speed to ensure that the carpet always maintains a uniform tension); the rewinding deviation rectification unit real-time detects the edge position of the multi-layer composite carpet on the rewinding roller through a camera during the rewinding process, and transmits the position data to the control module to determine whether the edge position is within the appropriate range of the rewinding roller. When it is detected that the edge position deviates from the preset distance, the control module drives the rewinding roller to adjust the position, so that the multi-layer composite carpet returns to the correct rewinding path and ensures that the edge of the rewound carpet is neat.

[0025] Specifically, for the first hot air of the top air outlet unit, the temperature is 60 °C, the wind speed is 5 m / s, and the circulation frequency is 10 times per minute, which quickly dries the top layer of the multi-layer composite carpet (generally the wool fiber surface layer) and takes away the vaporized moisture;

[0026] For the second hot air of the middle air outlet unit, the temperature is 80 °C, and the hot air is evenly distributed through the porous air duct. The wind speed is 3 m / s, and the circulation frequency is 8 times per minute, which deeply dries the middle layer of the multi-layer composite carpet (generally the chemical fiber middle layer);

[0027] For the third hot air of the bottom air outlet unit, the temperature is 70 °C, the wind speed is 4 m / s, and the circulation frequency is 9 times per minute, ensuring that the bottom layer of the multi-layer composite carpet (generally the rubber composite bottom layer) is fully dried.

[0028] More specifically, waste heat recovery units are provided at the air outlets of the top air outlet unit, the bottom air outlet unit, and the middle air outlet unit. The heat in the discharged high-temperature hot air is recovered through a heat exchanger, and the recovered heat is used to preheat the fresh air entering the drying module, and the fresh air is preheated through heat exchange before entering each air outlet unit (reducing the energy consumption of the hot air system).

[0029] Furthermore, the drying module further includes a humidity detection unit. The humidity detection unit detects the humidity of the top layer, the middle layer, and the bottom layer of the multi-layer composite carpet respectively and transmits the obtained humidity data to the control module. The control module determines whether the humidity of the top layer, the middle layer, and the bottom layer of the multi-layer composite carpet reaches the corresponding drying standard. If it reaches, the corresponding air outlet unit is closed, otherwise, the drying continues.

[0030] Furthermore, when the control unit detects that the winding diameter of the multi-layer composite carpet reaches the threshold, it controls the winding motor to stop driving the winding roller.
