Detailed Implementation

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0017] Specifically, such as Figure 1As shown in the embodiment of this application, a dynamic bonding device for synthetic leather is provided, specifically including: a first roller conveyor 100, a second roller conveyor 200, a first heating device 300, a second heating device 400, and a diversion device 500, specifically: Release paper is placed on the first roller conveyor 100. The release paper is advanced by the rotation of the rollers on the first roller conveyor 100. A second roller conveyor 200 is set on one side of the first roller conveyor 100. One end of the second roller conveyor 200 is located on the first roller conveyor 100. A pressure roller 210 is installed on the second roller conveyor 200. A base fabric is placed on the second roller conveyor 200. The base fabric is bonded to the release paper by the drive of the pressure roller 210 to form synthetic leather. The synthetic leather moves on the first roller conveyor 100.

[0018] Before the release paper and the base fabric are bonded, an applicator 110 is provided on the release paper. The applicator 110 applies glue to the side of the release paper facing the base fabric to bond the base fabric and the release paper, so as to facilitate the formation of synthetic leather.

[0019] After the synthetic leather bonding is completed, it needs to undergo high-temperature treatment. This high-temperature treatment is carried out by a first heating device 300 and a second heating device 400, specifically as follows: In this application, the first heating device 300 is connected to the first roller conveyor 100. The first heating device 300 is provided with a pressing member 310 and a heating device 320. The pressing member 310 presses the synthetic leather, which facilitates the heating device 320 to heat the synthetic leather. The pressing member 310 is installed on the first roller conveyor 100 through a support frame. The pressing member 310 includes multiple pressing blocks 311 and pressing rods 312. The pressing rods 312 are installed on the first heating device 300 and are positioned in the direction of movement of the synthetic leather. Multiple pressing blocks 311 are provided on one end of the pressing rods 312 facing the synthetic leather. The multiple pressing blocks 311 are movably connected to the pressing rods 312, and the multiple pressing blocks 311 press the synthetic leather by their own weight. The pressing member 310 is located on both sides of the first heating device 300, so that the heating device 320 is located between the two pressing members 310.

[0020] In the above, the pressing block 311 slightly compresses the synthetic leather in this application to avoid seepage and floating in this application.

[0021] Preferably, in this application, a telescopic motor is also provided on the pressure rod 312, and the pressure rod 312 in this application is controlled by the telescopic motor to facilitate the adjustment of the pressing force of the pressure block 311 on the synthetic leather.

[0022] Preferably, in this application, the pressure block 311 is detachably connected to the pressure rod 312 to facilitate the adjustment of the pressure on the synthetic leather.

[0023] In the first heating device 300, the heating device 320 consists of multiple heating elements 321 and a temperature detector 322. The multiple heating elements 321 are arranged in a rectangular shape in the first heating device 300, which can uniformly heat the synthetic leather and avoid uneven heating of some parts of the synthetic leather, thus avoiding quality problems.

[0024] The heating element 321 is specifically located at the bottom or top of the first roller conveyor 100. In this application, it is preferably located at the top to facilitate heating of the synthetic leather.

[0025] In this embodiment, the heating element 321 is more preferably provided at both the bottom and top of the first roller conveyor 100, so that the synthetic leather is heated more evenly.

[0026] Heating element 321 preheats the synthetic leather, and the heating temperature is stepped, ranging from 90 to 110 degrees Celsius. This stepped heating occurs along the direction of movement of the synthetic leather. Specifically: like Figures 2-3 As shown in the embodiment of this application, the heating element 321 is laid out in a long strip along the direction of the synthetic leather, and the heat released by each heating element 321 is fixed, so that one end of the long strip heating element 321 has a heating range of 90 degrees Celsius, the other end has a heating range of 110 degrees Celsius, and the heating temperature in the middle part increases by 5 degrees to form each heating area, so as to perform stepped heating of the synthetic leather.

[0027] During the heating process, the temperature of the synthetic leather needs to be controlled at all times to avoid excessively high or low temperatures. To avoid this, the temperature detector 322 in this application detects the surface temperature of the synthetic leather to control the temperature adjustment of the heating unit in each area.

[0028] In the second heating device 400, the heater 410 is located above the synthetic leather. The heater 410 performs secondary heating on the synthetic leather, and the temperature range of the heater 410 on the synthetic leather is 110-145 degrees Celsius. The heater 410 performs staged gradient heating on the synthetic leather.

[0029] In this application, the heating stage of the heater 410 for the second heating is the same as that of the heater 410 for the first heating, and will not be described in detail here.

[0030] In the second heating, a temperature detector 322 is also provided. The temperature detector 322 detects the temperature range of the second heating and thus controls the temperature range of the synthetic leather.

[0031] Its control method is the same as the temperature control for the first heating.

[0032] After being heated twice, the synthetic leather enters the cutting device 600, which can cut the synthetic leather into sections for sorting and categorizing.

[0033] The cutting device 600 is also equipped with a detection device 610, which can detect the degree of penetration of the segmented synthetic leather and mark the segmented synthetic leather so that the synthetic leather is divided into qualified synthetic leather and unqualified synthetic leather.

[0034] When synthetic leather shows obvious signs of penetration, it is considered a substandard product. When synthetic leather does not show obvious signs of penetration, it is considered a qualified product. In this case, the synthetic leather can be marked to record whether it is qualified or not.

[0035] After the synthetic leather is marked, it needs to be sorted. A sorting device 500 is installed to handle this. Figure 2 and Figure 4 As shown, the diversion device 500 includes a diversion plate 530, a first channel 510, and a second channel 520. The diversion plate 530 is equipped with a motor 531 and a steering roller 532. The steering roller 532 is connected to the output end of the motor 531. The motor 531 controls the rotation of the steering roller 532 to divert the synthetic leather, so that qualified synthetic leather enters the first channel 510 and unqualified synthetic leather enters the second channel 520. Among them, motor 531 is a servo motor 531.

[0036] Multiple steering rollers 532 are provided, and all of them are installed in the same direction. All of the steering rollers 532 are driven by a motor 531 for steering.

[0037] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
