Technical Field

[0001] This utility model belongs to the field of carpet lamination production technology, specifically relating to a cooling device for carpet lamination machines. Background Technology

[0002] In the carpet lamination process, after the lamination rollers press the carpet together, rapid cooling is required to ensure the carpet's flatness and quality. However, traditional cooling methods often suffer from low cooling efficiency and uneven cooling, easily leading to defects such as carpet deformation and wrinkles. Therefore, a cooling device capable of efficient and uniform cooling is needed. Summary of the Invention

By symmetrically arranging an upper air-cooling mechanism and a lower air-cooling mechanism, it can simultaneously cool both sides of the laminating roller, thereby improving cooling efficiency. The angle of the air guide plate is adjustable, allowing for flexible adjustment of the air outlet direction according to the carpet thickness and cooling requirements, ensuring uniformity of the cooling effect. A flow equalization net is installed inside the air duct to effectively distribute the airflow evenly and avoid carpet deformation caused by local temperature differences.

[0004] To achieve the above objectives, the specific technical solution of this application is as follows:

[0005] A cooling device for a carpet laminating machine includes an upper air-cooling mechanism and a lower air-cooling mechanism, which are symmetrically arranged on the upper and lower sides of the laminating pressure roller. Each of the upper and lower air-cooling mechanisms includes a fan, a guide plate, and an air duct. The fan is connected to the working surface of the laminating pressure roller through the air duct.

[0007] Furthermore, the fan is a variable frequency fan, and its speed is dynamically adjusted by the PLC control system according to the real-time monitoring signal of the temperature sensor, which is located on the discharge side of the composite pressure roller.

[0008] Furthermore, the air duct is equipped with a flow equalization net to evenly distribute airflow and prevent local temperature differences from causing carpet deformation.

[0009] Furthermore, the bottom of the air duct of the lower air-cooling mechanism is provided with a negative pressure dust suction port, which is connected to an external dust removal system to absorb dust and fiber debris generated during the cooling process.

[0010] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] It should be noted that the terms "upper," "lower," "left," "right," "front," and "rear" used in the following description refer to the directions shown in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Furthermore, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 and Figure 2 As shown, an embodiment of a cooling device for a carpet laminating machine includes an upper air-cooling mechanism and a lower air-cooling mechanism, which are respectively installed above and below the laminating pressure roller, arranged symmetrically. Both the upper and lower air-cooling mechanisms include a fan, an air guide plate, and an air duct. The fan is connected to the working surface of the laminating pressure roller through the air duct. The air guide plate has an adjustable angle structure to adjust the air outlet direction. The laminated carpet is pressed by the laminating pressure roller.

[0022] The angle adjustment mechanism of the air guide plate includes a servo motor, a rotating shaft, and angle limiting blocks. The servo motor is fixed on a mounting bracket on the outside of the air duct, and its output shaft is rigidly connected to the rotating shaft. The rotating shaft passes through the rotation center of the air guide plate. Angle limiting blocks are symmetrically arranged on both sides of the rotating shaft to limit the rotation angle range of the air guide plate. An encoder is integrated inside the servo motor, which can provide real-time feedback of the rotation angle of the air guide plate to the PLC control system to achieve precise angle control. Several sets of rotating shafts and air guide plates are provided, evenly distributed at the end of the air duct. Several rotating shafts are driven synchronously by the servo motor through gear sets or belts.

[0023] The air guide plate's adjustable angle range is set from 10° to 80°, which can adapt to the cooling needs of carpets of different thicknesses. When the air guide plate angle is adjusted to a smaller angle (such as 10°), the airflow blows towards the carpet surface in a near-vertical direction. The airflow has stronger penetration and can penetrate deep into the carpet, quickly removing heat from multiple layers of material and preventing a decrease in adhesive strength due to heat retention.

[0024] When using a thinner carpet, adjust the air deflector to a larger angle (e.g., 80°) so that the airflow covers the carpet surface at a parallel or inclined angle, forming a uniform "air curtain" to avoid localized overcooling or airflow impact that could cause deformation of the thin material.

[0025] The fan is a variable frequency fan, and its speed is dynamically adjusted by the PLC control system based on real-time monitoring signals from the temperature sensor. The temperature sensor is located on the discharge side of the composite pressure roller, which can monitor the carpet temperature in real time and transmit the signal to the PLC control system. The PLC control system automatically adjusts the fan speed according to the temperature signal to achieve the best cooling effect.

[0026] The air duct is equipped with a flow equalization mesh to evenly distribute airflow and prevent carpet deformation caused by localized temperature differences. The flow equalization mesh uses a multi-layered mesh structure to effectively disperse airflow, making the airflow more uniform.

[0027] The bottom of the air duct of the lower air-cooling unit is equipped with a negative pressure dust suction port, which connects to an external dust removal system to absorb dust and fiber debris generated during the cooling process. The negative pressure dust suction port can generate a certain negative pressure to draw dust and fiber debris into the dust removal system, maintaining a clean production environment.

[0028] Working Principle: After the composite carpet is pressed by the composite rollers, the upper and lower air-cooling mechanisms start simultaneously. A fan delivers cool air to the working surface of the composite rollers through an air duct to cool the carpet. The air guide plate, adjusted by a servo motor according to the carpet thickness and cooling requirements, ensures optimal airflow direction. A temperature sensor monitors the carpet temperature in real time and transmits the signal to the PLC control system. The PLC control system automatically adjusts the fan speed based on the temperature signal, achieving dynamic cooling control. A flow distribution mesh within the air duct ensures even airflow distribution, preventing carpet deformation caused by localized temperature differences. The negative pressure suction port of the lower air-cooling mechanism absorbs dust and fiber debris generated during the cooling process, maintaining a clean production environment.

[0029] In summary, this application has a simple structure. By symmetrically arranging the upper and lower air-cooling mechanisms, it can simultaneously cool both sides of the composite pressure roller, thereby improving cooling efficiency. The angle of the air guide plate is adjustable, which can flexibly adjust the air outlet direction according to the thickness of the carpet and the cooling requirements, ensuring the uniformity of the cooling effect. A flow equalization net is set in the air duct to effectively and evenly distribute the airflow and avoid carpet deformation caused by local temperature differences.

[0030] It should be noted that the accompanying drawings merely illustrate the technical concept of the present invention and should not be used to limit the scope of protection of the present invention. For those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and all such improvements and modifications fall within the scope of protection of the claims of the present invention.
