Description

Technical Field

[0001] The utility model relates to the technical field of automobile carpet composite production lines, in particular to an automobile composite carpet heating device. Background Art

[0002] Currently, composite fabrics for automotive carpets are typically formed by bonding two fabric layers together with an adhesive layer. During this bonding process, the hot-melt powder applied to the surface of the first fabric layer must first be melted. In existing technology, this hot-melt powder is typically melted in an oven. However, because the oven is long and the heating mechanism is located in only one area, temperature differences occur within the oven. Furthermore, the hot-melt powder applied to the first fabric layer has varying thicknesses at different locations. This results in incomplete melting of the hot-melt powder at different locations, which in turn reduces the quality of the composite fabric. Utility Model Content

[0020] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0021] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0022] like Figure 1 and Figure 2 As shown, a composite carpet heating device for automobiles provided by the present invention includes an oven 1, a conveyor belt 2, and a controller. An inlet and an outlet are respectively provided on two opposite sides of the oven 1. Both ends of the conveyor belt 2 pass through the oven 1 and carry the carpet into the oven 1 along the direction from the inlet to the outlet. A heating mechanism is provided inside the oven 1, and the heating mechanism includes a heating plate 3. The heating plate 3 is located above the conveyor belt 2 and is parallel to the conveying direction of the conveyor belt 2. A plurality of groups of heating units are provided on the heating plate 3. The plurality of groups of heating units are spaced apart along the extension direction of the heating plate 3 to form a plurality of heating areas inside the oven 1. Each group of heating units corresponds to a heating area. Each heating area is provided with a temperature sensor. The temperature sensor is electrically connected to the controller, and the controller is electrically connected to the heating unit.

[0023] In this embodiment, a carpet is coated with hot-melt powder by a powdering mechanism and then conveyed by a conveyor belt 2 into an oven 1 for heating. After being heated in oven 1, the hot-melt powder forms a bonding layer on the carpet's surface, which then bonds with another carpet to form a composite carpet. Typically, oven 1 is only equipped with a heating mechanism for melting the hot-melt powder. However, due to varying amounts of powder applied to the carpet surface and temperature differences at different locations within oven 1, the hot-melt powder melts incompletely and unevenly, resulting in reduced carpet composite quality. To address this issue, oven 1 in this embodiment employs a zoned heating mode for temperature control. Specifically, multiple heating units are provided on a heating plate 3 to create multiple heating zones within oven 1. The temperature of each heating zone is monitored by a temperature sensor. A controller controls the operation of the heating units based on the temperature information fed back by the temperature sensors. This allows for adjustable temperatures in different zones within oven 1, ensuring that the hot-melt powder on the carpet surface is uniformly molten, thereby improving the hot-melt powder's melting quality.

[0024] As a preferred embodiment, a servo thermostat is further included, the controller is electrically connected to the servo thermostat, the servo thermostat is electrically connected to the temperature sensor, and the servo thermostat is electrically connected to the heating unit.

[0025] In this embodiment, in order to more accurately control the operation of the heating unit and to adapt to the heating melting points of different hot-melt powders, the controller of this embodiment can preset a temperature value and transmit the information to the servo thermostat. The servo thermostat controls the heating unit to start heating. At the same time, the temperature sensor starts to provide temperature feedback on the temperature in the oven 1 and feeds back the real-time temperature information to the servo thermostat. After receiving the feedback information, the servo thermostat compares the set temperature value transmitted by the controller with the feedback value of the temperature sensor, and outputs the heating power to the heating unit according to the size of the comparison value. That is, when the temperature difference of the comparison value is too large, the output power of the heating unit is increased, and when the temperature difference of the comparison value is small, the output power of the heating unit is reduced. Since the servo thermostat can intelligently adjust and control the output power of the heating unit according to the real-time temperature in the oven 1, the temperature fluctuation of the oven 1 is very small, and the temperature control accuracy is within ±1°C, which can effectively improve the hot-melt quality of the hot-melt powder. In addition, since the servo thermostat can intelligently control the output power of the heating unit, it solves the energy waste problem of the previous heating unit always outputting full power for heating.

[0026] As a preferred embodiment, each group of heating units includes a plurality of heating tubes 4 , and the extension direction of the plurality of heating tubes 4 is arranged perpendicular to the conveying direction of the conveyor belt 2 .

[0027] As a preferred embodiment, the heating tube 4 of each heating unit group is detachably connected to the interior of the heating plate 3. When the heating tube 4 needs to be replaced or repaired, it can be replaced by simply removing the heating tube 4 from the heating plate 3, which improves the problem of difficulty in replacing and repairing the heating tube 4.

[0028] As a preferred embodiment, the heating tube 4 is an infrared heating tube 4. Infrared heat radiation heating has the advantages of high thermal efficiency, fast heating speed, and long service life.

[0029] As a preferred embodiment, the conveyor belt 2 is a Teflon mesh conveyor belt. Teflon mesh conveyor belts are characterized by high temperature resistance and high air permeability. The mesh size of the Teflon mesh conveyor belt in this embodiment is preferably 5mm, which is conducive to uniform temperature conduction and can better support the carpet surface for smooth transportation.

[0030] As a preferred embodiment, the heating mechanism further includes a lifting assembly for driving the heating plate 3 to move upward and downward. In this embodiment, the lifting assembly drives the heating plate 3 to move upward and downward, so that the distance between the heating unit and the carpet surface can be automatically adjusted to adjust the optimal heating distance required by different carpets.

[0031] As a preferred embodiment, the lifting assembly includes multiple lifting units 5, a transmission mechanism 6 and a driving member 7. One end of each lifting unit 5 is connected to the top of the heating plate 3, and the other end of each lifting unit 5 is connected to the driving member 7 through the transmission mechanism 6. The driving member 7 links the multiple lifting units 5 to rise and fall synchronously through the transmission mechanism 6.

[0032] In this embodiment, multiple lifting units 5 are driven to rise and fall synchronously by only one driving member 7, which has a simple structure and stable operation, effectively ensuring the absolute synchronization of the lifting units 5, improving the reliability and stability of the operation of the entire heating plate 3, reducing the equipment failure rate, and reducing the equipment manufacturing and maintenance costs.

[0033] As a preferred embodiment, the transmission mechanism 6 includes two first transmission rods 61 parallel to each other and a second transmission rod 62 vertically connected to the two first transmission rods 61, and the two ends of the second transmission rod 62 are respectively connected to the middle parts of the two first transmission rods 61, and the ends of the second transmission rod 62 are connected to the middle parts of the first transmission rods 61 through a right-angle commutator. The ends of the two first transmission rods 61 each drive one of the lifting units 5, and the second transmission rod 62 is connected to the driving member 7 and is driven to rotate by the driving member 7.

[0034] During operation, the driving member 7 drives the second transmission rod 62 to rotate, and the two ends of the second transmission rod 62 respectively drive the two first transmission rods 61 to rotate through the right-angle commutator. The two ends of each first transmission rod 61 drive a group of lifting units 5 to lift and lower. The two first transmission rods 61 can drive four groups of lifting units 5 to perform synchronous lifting operations.

[0035] The drive member 7 of this embodiment drives the four groups of lifting units 5 to rise and fall synchronously via the transmission mechanism 6. This streamlined overall structure minimizes the production material and processing and installation costs of the drive member 7, improving the smoothness of the heating unit's rise and fall and its load-bearing capacity, thus enabling a wide range of applications. Furthermore, the "I"-shaped transmission structure, in which a second transmission rod 62 drives two first transmission rods 61, ensures good drive synchronization between the lifting units 5, facilitating precise control of the degree of elevation of the lifting units 5. The drive member 7 of this embodiment is preferably a motor. In other embodiments, the drive member 7 may alternatively be another drive component capable of rotating the second transmission wire.

[0036] As a preferred embodiment, the lifting unit 5 includes a lifting screw 51 and a protective box 52. The protective box 52 is arranged on the top of the oven 1. The lower end of the lifting screw 51 is movable through the oven 1 and is fixedly connected to the heating plate 3. The upper end of the lifting screw 51 passes through the protective box 52 and is connected to the thread of the protective box 52. The upper part of the lifting screw 51 is connected to the end of the first transmission rod 61 through a bevel gear set. The connection between the lifting screw 51 and the first transmission rod 61 is located in the protective box 52. In this embodiment, the connection between the lifting screw 51 and the first transmission rod 61 is hidden by the protective box 52, which not only provides safety protection and makes the product more beautiful, but also makes the installation and adjustment of the lifting screw 51 more convenient.
