[0027] 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.

[0028] 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.

[0029] like Figure 1-9As shown, the present invention provides an automotive carpet composite production line, comprising a first feeding mechanism 10, a second feeding mechanism 20, a powder sprinkling mechanism 30, a heating mechanism 40, a pressing mechanism 50, and a turning mechanism 60, which are sequentially arranged along a conveying direction. The first feeding mechanism 10 is used to convey a carpet surface layer to the pressing mechanism 50, and the second feeding mechanism 20 is used to convey a carpet bottom layer to the powder sprinkling mechanism 30. The powder sprinkling mechanism 30 is used to sprinkle hot melt powder on the surface of the carpet bottom layer and convey it to the heating mechanism 40. The heating mechanism 40 is used to heat the hot melt powder on the surface of the carpet bottom layer. The pressing mechanism 50 is used to press the heated carpet bottom layer and the carpet surface layer to form a composite carpet. The composite carpet emerging from the pressing mechanism 50 enters the turning mechanism 60, and is turned over by the turning mechanism 60 so that the bottom surface of the composite carpet faces upward.

[0030] In this embodiment, the carpet surface layer is conveyed to the powder sprinkling mechanism 30 by the first feeding mechanism 10, and the carpet surface layer is conveyed to the compounding mechanism by the second feeding mechanism 20, so that the carpet surface layer and the carpet bottom layer are conveyed at the same time, thereby improving production efficiency; thereafter, the carpet bottom layer is automatically powdered by the powder sprinkling mechanism 30, thereby improving powder sprinkling efficiency and powder sprinkling quality; then, the hot melt powder on the surface of the carpet bottom layer is heated by the heating mechanism 40 to ensure that the hot melt powder on the carpet surface can reach a molten state, and then the carpet surface layer and the carpet bottom layer are quickly compounded by the pressing mechanism 50, and finally, the compound carpet is automatically turned over by the turning mechanism 60, without the need for manual operation to different workstations, and without the need for manual loading and turning, thereby high production efficiency and reduced production costs, and at the same time, the powder sprinkling, heating and compounding processes are closely coordinated, which can realize automatic control and effectively ensure the quality of the compound carpet.

[0031] As a preferred embodiment, the flip mechanism 60 includes a flip bracket 61, on which a first guide roller 62 arranged perpendicular to the conveying direction, a second guide roller 63 arranged at 45 degrees to the first guide roller 62, a third guide roller 64 arranged parallel to the conveying direction, a fourth guide roller 65 arranged at 45 degrees to the third guide roller 64, and a fifth guide roller 66 arranged at 45 degrees to the fourth guide roller 65 are rotatably arranged. The top surfaces of the first guide roller 62 and the second guide roller 63 are at the same height, and the third guide roller 64 is arranged parallel to the conveying direction. 4. The top surfaces of the fourth guide roller 65 and the fifth guide roller 66 are at the same height and are both located below the second guide roller 63. The composite carpet emerging from the laminating mechanism 50 contacts the upper surface of the first guide roller 62 and is then guided downward around the second guide roller 63. The composite carpet emerging from the second guide roller 63 then passes downward around the third guide roller 64. The composite carpet emerging from the third guide roller 64 then passes downward around the fourth guide roller 65. The composite carpet emerging from the fourth guide roller 65 contacts the upper surface of the fifth guide roller 66 and is guided downward.

[0032] In this embodiment, the composite carpet emerges from the laminating mechanism 50 with its top surface facing upward, with the carpet surface layer facing upward. Subsequent processes require the composite carpet to be turned upward with its bottom surface facing upward. Traditionally, turning composite carpets is a manual process, which is labor-intensive and inefficient. In this embodiment, after the composite carpet emerges from the laminating mechanism 50, it passes through the first guide roller 62 with its top surface facing upward. It then passes over the second guide roller 63 from top to bottom. After exiting the second guide roller 63, it passes over the third guide roller 64 from top to bottom. After exiting the third guide roller 64, it passes over the fourth guide roller 65 from top to bottom. After exiting the fourth guide roller 65, it passes over the fifth guide roller 66 with its bottom surface facing upward. The ingenious design of the first, second, third, fourth, and fifth guide rollers 62, 63, 64, and 65 allows for convenient and quick automated turning of the composite carpet, significantly reducing labor and occupying a minimal footprint.

[0033] As a preferred embodiment, the powder sprinkling mechanism 30 includes a powder sprinkling bin 31, a powder sprinkling roller 32, a powder sprinkling drive for driving the powder sprinkling roller 32 to rotate, a screen 33 and a screen 33 drive for driving the screen 33 to vibrate. A powder outlet is provided at the bottom of the powder sprinkling bin 31, and the powder sprinkling roller 32 is rotatably arranged at the powder outlet of the powder sprinkling bin 31. The axis of the powder sprinkling roller 32 is parallel to the extension direction of the powder outlet. A plurality of powder receiving grooves are evenly distributed along the circumferential direction on the outer surface of the powder sprinkling roller 32. The extension direction of the powder receiving grooves is parallel to the axis of the powder sprinkling roller 32. The screen 33 is located below the powder sprinkling roller 32 and parallel to the extension direction of the powder sprinkling roller 32.

[0034] In this embodiment, after the carpet bottom layer enters the powder sprinkling mechanism 30, the powdering roller 32 sprinkles the powder in the powder sprinkling bin 31 onto the surface of the carpet bottom layer. The specific process is: the powder in the powder sprinkling bin 31 enters the powder receiving groove on the powder sprinkling roller 32 from the powder outlet, and then the powder sprinkling driving member drives the powder sprinkling roller 32 to rotate, and then the powder on the powder sprinkling roller 32 is sprinkled onto the screen 33 through rotation. The powder that falls on the screen 33 is vibrated and then sprinkled on the surface of the carpet bottom layer. Since the powder is sieved again by the high-frequency vibrating screen 33 during the falling process, the powder can be sprinkled more evenly and the powder distribution is finer, thereby ensuring that the powder is evenly sprinkled on the surface of the carpet bottom layer.

[0035] Specifically, in order to prevent the powder on the powdering roller 32 from adhering to the powder receiving trough and affecting the powdering, a plurality of brushes (not shown in the figure) are provided below the powdering roller 32. The brushes extend along the axis of the powdering roller 32 and are fixed relative to the powdering roller 32. The brushes are used to brush the powder in the powder receiving trough onto the screen 33. In this embodiment, the powder on the powdering roller 32 is brushed off by the brushes. On the one hand, this ensures that the powdering roller 32 can operate normally. On the other hand, the brushes can refine the powder and further improve the powdering effect.

[0036] As a preferred embodiment, the screen 33 includes a first layer of screen 33 and a second layer of screen 33 arranged in an upper and lower manner. The powder is vibrated and screened twice by the double-layer screen 33, so that the powder can be broken up and refined, thereby further improving the powdering effect.

[0037] In addition, in order to achieve a better vibration effect, the screen 33 driving assembly includes a first screen 33 driving member for driving the first layer of screen 33 to vibrate and a second screen 33 driving member for driving the second layer of screen 33 to vibrate. In this embodiment, the first layer of screen 33 and the second layer of screen 33 are vibrated respectively by the first screen 33 driving member and the second screen 33 driving member, which can better control the vibration frequency of different layers of screen 33 to achieve a better vibration effect. In this embodiment, the first screen 33 driving member and the second screen 33 driving member can be a vibration motor, wherein the vibration motor includes a body and a motor shaft, and a cam is installed at the shaft end of the motor shaft. The cam is placed at the lower part of the screen 33, and the cam is in contact with the screen 33. The rotation of the vibration motor drives the rotation of the cam, and the rotation of the cam causes the screen 33 to be squeezed and released to reciprocate, causing the screen 33 to vibrate.

[0038] As a preferred embodiment, the powder spreading drive member is a powder spreading motor, which can adjust the number of revolutions of the powder spreading roller 32 to achieve quantitative powder dropping. By driving the powder spreading roller 32 to rotate by the powder spreading motor, the rotation speed of the powder spreading roller 32 can be precisely controlled to achieve the effect of quantitative powder spreading.

[0039] As a preferred embodiment, the powder spreading mechanism 30 further includes a powder storage bucket 36, a powder delivery pipe 37, and a vacuum pumping assembly. The powder storage bucket 36 is connected to the powder spreading bin 31 via the powder delivery pipe 37, and the powder spreading bin 31 is connected to the vacuum pumping assembly via a pipe. In this embodiment, the powder spreading bin 31 is provided with a sealing cover (not shown in the figure). When the powder spreading bin 31 needs to be refilled with powder, the powder in the powder storage bucket 36 is pumped into the powder spreading bin 31 via the vacuum pumping assembly, thereby achieving an automatic loading function. Since the loading is achieved by vacuum pumping, the loading efficiency is improved. At the same time, compared with traditional manual loading, there is no dust pollution.

[0040] Specifically, an upper hopper 38 is provided at the output end of the powder delivery pipe 37. The powder discharge end of the upper hopper 38 is configured in a conical structure. In this embodiment, the powder discharge port of the upper hopper 38 extends into the sealing cover. The upper hopper 38 smoothly guides the powder into the powder spreading bin 31. At the same time, the conical structure of the powder discharge end ensures uniform powder discharge and prevents powder from adhering to the inner circumference of the upper hopper 38.

[0041] As a preferred embodiment, the powder spreading mechanism 30 also includes a low limit switch (not shown in the figure) and a high limit switch 39, and the low limit switch and the high limit switch 39 are both connected to the controller, and the controller is electrically connected to the vacuum pumping component. The low limit switch and the high limit switch 39 are both arranged on the inner wall of the powder spreading bin 31, and the low limit switch is used to detect whether the powder in the powder spreading bin 31 reaches the first set height, and the high limit switch 39 is used to detect whether the powder in the powder spreading bin 31 reaches the second set height. The low limit switch and the high limit switch 39 can both generate height information and provide the generated height information to the controller, and the controller controls the start or stop of the vacuum pumping component according to the height information.

[0042] In this embodiment, when the powder level in the powder spreading bin 31 is lower than a first set height, the low limit switch generates low level information and provides the generated low level information to the controller. The controller controls the activation of the vacuum assembly based on the low level information, and the vacuum assembly draws the powder in the powder storage bucket 36 into the powder spreading bin 31. When the powder level in the powder spreading bin 31 is higher than a second set height, the high limit switch 39 generates high level information and provides the generated high level information to the controller. The controller controls the deactivation of the vacuum assembly based on the high level information. The powder level in the powder spreading bin 31 can be accurately controlled by the low limit switch and the high limit switch 39.

[0043] In a preferred embodiment, the powder spreading mechanism 30 further includes a guide rod 34, a powder leveling plate 35 movably mounted on the guide rod 34, and a powder leveling drive assembly for driving the powder leveling plate 35 to reciprocate on the guide rod 34. The guide rod 34 is positioned within the powder spreading bin 31 and extends along the length of the bin 31. In this embodiment, the movable powder leveling plate 35 pushes the powder toward both sides of the bin 31, thereby preventing the powder from accumulating in the center of the bin 31. Furthermore, the movement of the powder by the powder leveling plate 35 also prevents the powder from agglomerating.

[0044] The powder distribution drive assembly includes a powder distribution motor and a transmission assembly. The guide rod 34 is a screw, and one end of the powder distribution plate 35 is threadedly connected to the screw via a nut. Both ends of the screw are rotatably connected to the powder distribution bin 31, and one end extends outside the powder distribution bin 31 to connect to the output end of the powder distribution motor via the transmission assembly. In this embodiment, the powder distribution motor drives the screw to rotate via the transmission assembly. The rotation of the screw drives the nut to move along the axis of the screw, which in turn drives the powder distribution plate 35 to reciprocate on the screw.

[0045] Specifically, the transmission assembly includes a first sprocket, a second sprocket and a transmission chain. The first sprocket is fixed on the screw rod, the second gear is installed on the output shaft of the powder pushing drive motor, and the first sprocket and the second sprocket are connected in transmission through the transmission chain.

[0046] As a preferred embodiment, the heating mechanism 40 includes an oven 401, a conveyor belt 402, and a controller. An entrance and an exit are respectively provided on two opposite sides of the oven 401. Both ends of the conveyor belt 402 pass through the oven 401 and carry the carpet into the oven 401 along the direction from the entrance to the exit. A liftable heating plate 403 is provided inside the oven 401. The heating plate 403 is located above the conveyor belt 402 and parallel to the conveying direction of the conveyor belt 402. The heating plate 403 is provided with multiple groups of heating units. The multiple groups of heating units are arranged at intervals along the extension direction of the heating plate 403 to form multiple heating zones inside the oven 401. Each group of heating units corresponds to a heating zone. Each heating zone 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.

[0047] In this embodiment, after the carpet base layer is sprinkled with hot-melt powder by powdering mechanism 30, it is then transported by conveyor belt 402 into oven 401 for heating. After being heated in oven 401, the hot-melt powder forms a bonding layer on the carpet base layer, which then bonds to the carpet top layer to form a composite carpet. Typically, oven 401 is only equipped with heating mechanism 40 to melt the hot-melt powder. However, due to varying amounts of powder applied to the carpet surface and temperature differences at different locations within oven 401, the hot-melt powder may not melt thoroughly and evenly, resulting in reduced carpet composite quality. To address this issue, the oven 401 of this embodiment adopts a zoned heating mode for temperature-controlled heating. Specifically, multiple groups of heating units are provided on the heating plate 403 to form multiple heating zones within the oven 401. The temperature of each heating zone is monitored by a temperature sensor, and the controller controls the operation of the heating unit based on the temperature information fed back by the temperature sensor. This allows the temperature in different zones within the oven 401 to be adjustable, ensuring that the hot-melt powder on the carpet surface is uniformly molten, thereby improving the hot-melt quality of the hot-melt powder.

[0048] In this embodiment, in order to more accurately control the operation of the heating unit and to adapt to different heating melting points of hot melt powder, the heating mechanism 40 also includes a servo temperature controller, the controller is electrically connected to the servo temperature controller, the servo temperature controller is electrically connected to the temperature sensor, and the servo temperature controller is electrically connected to the heating unit. In this embodiment, the controller can preset a temperature value and transmit the information to the servo temperature controller. The servo temperature controller 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 401 and feeds back the real-time temperature information to the servo temperature controller. After receiving the feedback information, the servo temperature controller 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 temperature controller can intelligently adjust the output power of the heating unit according to the real-time temperature in the oven 401, the temperature fluctuation of the oven 401 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 temperature controller can intelligently control the output power of the heating unit, it solves the problem of energy waste caused by the heating unit always outputting full power for heating.

[0049] As a preferred embodiment, each heating unit group includes several heating tubes 404, which extend perpendicularly to the conveying direction of the conveyor belt 402. The heating tubes 404 are infrared heating tubes. Infrared heat radiation heating offers advantages such as high thermal efficiency, rapid heating speed, and long service life. The heating tubes 404 in each heating unit group are detachably connected to the interior of the heating plate 403. When the heating tubes 404 need to be replaced or repaired, they can be simply removed from the heating plate 403, eliminating the difficulty of replacing or repairing the heating tubes 404.

[0050] As a preferred embodiment, the conveyor belt 402 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 5 mm, which is conducive to uniform temperature conduction and can better support the carpet surface for smooth transportation.

[0051] As a preferred embodiment, the heating mechanism 40 also includes a lifting component that drives the heating plate 403 to rise and fall. The lifting component includes multiple lifting units, a transmission mechanism and a lifting drive 409. One end of each lifting unit is connected to the top of the heating plate 403, and the other end of each lifting unit is connected to the lifting drive 409 through the transmission mechanism. The lifting drive 409 is linked to multiple lifting units through the transmission mechanism to rise and fall synchronously.

[0052] In this embodiment, the lifting assembly drives the heating plate 403 to move upward and downward, allowing for automatic adjustment of the distance between the heating unit and the carpet surface to achieve the optimal heating distance required for different carpets. Furthermore, this embodiment utilizes a single lifting drive 409 to synchronously lift multiple lifting units, resulting in a simple structure and stable operation. This effectively ensures absolute synchronization of the lifting units, improves the reliability and stability of the overall operation of the heating plate 403, reduces equipment failure rates, and lowers manufacturing and maintenance costs.

[0053] The transmission mechanism includes two mutually parallel first transmission rods 407 and a second transmission rod 408 perpendicularly connected to the two first transmission rods 407. The two ends of the second transmission rod 408 are respectively connected to the middle parts of the two first transmission rods 407. The ends of the second transmission rod 408 are connected to the middle parts of the first transmission rods 407 via a right-angle commutator. The ends of the two first transmission rods 407 each drive one of the lifting units. The second transmission rod 408 is connected to the driving member and is driven to rotate by the driving member. During operation, the lifting drive member 409 drives the second transmission rod 408 to rotate. The two ends of the second transmission rod 408 respectively drive the two first transmission rods 407 to rotate via the right-angle commutator. The two ends of each first transmission rod 407 drive a group of lifting units to lift and lower. The two first transmission rods 407 can drive four groups of lifting units to perform synchronous lifting operations.

[0054] The lifting drive 409 of this embodiment drives the four lifting units to rise and fall synchronously through a transmission mechanism. This streamlined overall structure minimizes the production material and processing and installation costs of the drive, 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 408 drives two first transmission rods 407, ensures good drive synchronization between the lifting units, facilitating precise control of the lifting degree of the lifting units. The lifting drive 409 of this embodiment is preferably a motor. In other embodiments, the lifting drive 409 may alternatively be another drive component capable of rotating the second transmission rod 408.

[0055] As a preferred embodiment, the lifting unit includes a lifting screw 405 and a protective box 406. The protective box 406 is arranged on the top of the oven 401.
