Description

Technical Field

[0001] This utility model relates to the field of fiber leather processing technology, specifically to a fiber leather composite heating device. Background Technology

[0002] Fiber leather is a synthetic material, usually made from island fiber nonwoven fabric as the base material. It is formed by impregnating polyurethane slurry and then wet solidifying it to form island fiber / polyurethane composite material. After fiber opening (dissolution method, alkali reduction or toluene reduction) treatment, and finally through different finishing processes, smooth or suede fiber leather with wear resistance, cold resistance, breathability and aging resistance can be produced. When hot pressing fiber leather, heating device is required to heat and soften the fiber leather.

[0003] For example, a heating device for PVC leather manufacturing, with application number CN201821022261.3 and authorization announcement date of 20190115, includes a heating box, a box cover, and several placement plates. The placement plates are fixed to the middle of the inner walls on both sides of the heating box via several brackets. A rotating shaft is provided between each pair of adjacent placement plates, with one end of the shaft penetrating the side wall of the heating box and positioned outside the box. A motor is installed on one side of the heating box, and the output end of the motor is connected to one end of one of the rotating shafts. A baffle plate is fixed to the side of the inner wall at the bottom of the heating box. This heating device for PVC leather manufacturing, with its heating tubes inside the heating box, can quickly conduct heat when used in conjunction with a heat-conducting plate, achieving uniform heating of the PVC synthetic leather at the top of the placement plates and avoiding excessively high local temperatures that could affect heating quality.

[0004] Traditional fiber leather heating devices mostly use jet heating. While this method can achieve the heating purpose, it is less effective at heating thicker fiber leather and cannot quickly heat thicker fiber leather to the predetermined temperature. Therefore, there is an urgent need to design a composite fiber leather heating device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fiber leather composite heating device to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fiber leather composite heating device includes a housing. Two electric push rods are bolted to both sides of the bottom of the inner wall of the housing, and the output ends of four electric push rods are bolted to a housing. Multiple lower heating rollers are mounted inside the housing via bearings. Multiple heat-absorbing covers are bolted to one side of the outer wall of the top of the housing, with one end of each heat-absorbing cover extending into the housing. An upper heating roller is mounted inside each heat-absorbing cover via bearings, positioned above the lower heating rollers. Two jetting assemblies are bolted to the inside of the housing, with one jetting assembly facing downwards and the other facing upwards. Connecting pipes are inserted into one side of the outer wall of each of the multiple heat-absorbing covers, with both ends of the connecting pipes extending into the two jetting assemblies respectively.

[0008] Furthermore, material inlets are provided on both outer walls of the box, and multiple guide rollers are installed inside the box via bearings.

[0009] Furthermore, the jet assembly includes a jet box, inside which two fans in contact with each other are bolted, and one end of the connecting pipe extends into the interior of the jet box.

[0010] Furthermore, the top of the jet box is threaded with multiple nozzles, and two heating tubes are bolted to the outer wall of one side of the jet box.

[0011] Furthermore, a dust collection assembly is bolted to one side of the outer wall of the housing. The dust collection assembly includes a dust collection hood, which is bolted to the top side of the housing. The bottom end of the dust collection hood extends into the housing, and the bottom end of the dust collection hood is opposite to the upward-facing jet assembly.

[0012] Furthermore, a dust collection box is bolted to one side of the outer wall of the box, and a connecting pipe is inserted into the top of the dust collection box. One end of the connecting pipe is connected to the dust collection hood. A dust collection pump is bolted to one side of the bottom of the dust collection box, and the dust collection pump is connected to the dust collection box through a pipe.

[0013] In the above technical solution, the fiber leather composite heating device provided by this utility model has the following beneficial effects:

[0014] With its electric push rod, housing, lower heating roller, and upper heating roller, this device heats fiber leather by first introducing the fiber leather into the chamber, then activating the electric push rod. The housing then lifts up multiple lower heating rollers, allowing the lower and upper heating rollers to heat fiber leather of different thicknesses. This method ensures direct contact between the heat source and the fiber leather, achieving uniform and rapid heating. Simultaneously, during the heating process, the lower and upper heating rollers can remove loose threads from the fiber leather through heating.

[0015] By using the connected pipes and air jet components, when heating the fiber leather, the fan inside the air jet box can be started. The started fan will draw heat from the heat-absorbing roller inside the heat absorption hood through the connected pipes. Subsequently, the air carrying the heat will be sprayed out through the nozzles to preheat or reheat the top and bottom sides of the fiber leather, realizing the utilization of preheating and composite heating of the fiber leather. At the same time, the upward-facing air jet components can remove dust from the fiber leather by air jetting.

[0016] With the dust collection component in place, when the device is used, the dust pump can be activated, which will create a negative pressure inside the dust collection box. Because of the negative pressure inside the dust collection box, the dust collection box will draw air from inside the dust collection hood through the connecting pipe. Subsequently, the dust collection hood will generate suction to adsorb dust and other impurities on the fiber leather, thus cleaning the fiber leather and improving the practicality of the device.

[0026] Specifically, in this embodiment, the enclosure includes a housing 1. Two electric push rods 8 are bolted to both sides of the bottom of the inner wall of the housing 1. The electric push rods 8 are preferably of the THK model. A housing 9 is bolted to the output ends of the four electric push rods 8. Multiple lower heating rollers 10 are mounted inside the housing 9 via bearings. When the four electric push rods 8 are activated, the output ends of the electric push rods 8 lift the housing 9, which in turn lifts the multiple lower heating rollers 10, causing the lower heating rollers 10 to lift the fiber leather, bringing the top of the fiber leather into contact with the upper heating roller 11. Multiple heat-absorbing covers 3 are bolted to the outer wall of one side of the top of the housing 1. The heat-absorbing covers 3 are made of heat-insulating material, and one end of each heat-absorbing cover 3 extends into the interior of the housing 1. Upper heating rollers are mounted inside the heat-absorbing covers 3 via bearings. The upper heating roller 11 and the lower heating roller 10 are preferably Herkules GTH-450 models. When the upper heating roller 11 and the lower heating roller 10 are started, they will generate heat. After a period of preheating, the fiber leather that the upper heating roller 11 and the lower heating roller 10 can contact will be heated. The upper heating roller 11 is located above the lower heating roller 10. Two jet assembly 7 are installed inside the housing 1 by bolts. One jet assembly 7 is facing downwards and the other jet assembly 7 is facing upwards. A connecting pipe 2 is inserted into the outer wall of one side of the multiple heat absorption hoods 3. The connecting pipe 2 facilitates the connection of the jet assembly 7 and the multiple heat absorption hoods 3 together. Both ends of the connecting pipe 2 extend into the two jet assembly 7 respectively.

[0027] This utility model provides a fiber leather composite heating device. When heating fiber leather using this device, the fiber leather can be first introduced into the housing 1, and then the electric push rod 8 can be activated. The housing 9 will lift up multiple lower heating rollers 10, so that the lower heating rollers 10 and the upper heating rollers 11 can heat fiber leather of different thicknesses. In this way, the heat source is in direct contact with the fiber leather, which can achieve uniform and rapid heating. At the same time, during the heating process, the lower heating rollers 10 and the upper heating rollers 11 can remove the threads on the fiber leather by heating.

[0028] In one embodiment provided by this utility model, such as Figure 1-2 As shown, both sides of the outer wall of the box 1 are provided with material inlets 5, which facilitate the entry and exit of the fiber leather into and out of the box 1. Multiple guide rollers 6 are installed inside the box 1 through bearings, which facilitate the movement of the fiber leather inside the box 1.

[0029] In another embodiment provided by this utility model, such as Figure 3 As shown, the jet assembly 7 includes a jet box 12. Inside the jet box 12, two fans 13 are bolted together and are in contact with each other. The fan 13 is preferably a 9G0624P4H003 anti-splash axial flow fan. One end of the connecting pipe 2 extends into the jet box 12. Multiple nozzles 15 are threadedly connected to the top of the jet box 12. Two heating tubes 14 are bolted to one side of the outer wall of the jet box 12. The heating tubes 14 are preferably 6200 infrared heating tubes. When the heating tubes 14 are started, they can heat the air inside the jet box 12. When the fans 13 and heating tubes 14 inside the jet box 12 are started, the started fans 13 will draw heat from the heat-absorbing roller 11 inside the heat-absorbing cover 3 through the connecting pipe 2. The air carrying heat will then be reheated by the heating tubes 14 and then sprayed out through the nozzles 15 to preheat or reheat the top and bottom sides of the fiber leather, realizing the utilization of preheating and composite heating of the fiber leather.

[0030] In another embodiment provided by this utility model, such as Figure 1 and Figure 4As shown, a dust collection assembly 4 is bolted to one outer wall of the housing 1. The dust collection assembly 4 includes a dust collection hood 16, which is bolted to the top outer wall of the housing 1. The bottom end of the dust collection hood 16 extends into the interior of the housing 1. The bottom end of the dust collection hood 16 is opposite to the upward-facing jet assembly 7. A dust collection box 17 is bolted to one outer wall of the housing 1. A dust discharge port is provided on one outer wall of the dust collection box 17, and a connecting pipe 19 is inserted into the top of the dust collection box 17. One end of the connecting pipe 19 is connected to the dust collection hood 16. A dust pump 18 is bolted to the bottom outer wall of the dust collection box 17. The dust pump 18 is of a superior model. Select an HG-120W / 220V (single-phase) vortex air pump. Start the vacuum pump 18. The vacuum pump 18 will put the dust collection box 17 into a negative pressure state. Because the dust collection box 17 is under negative pressure, it will draw air from the vacuum hood 16 through the connecting pipe 19. Then the vacuum hood 16 will generate suction to adsorb dust and other impurities on the fiber leather, thus cleaning the fiber leather. At the same time, the upward-facing jet component 7 can remove dust from the fiber leather by jetting air. The two work together to clean both sides of the fiber leather. The vacuum pump 18 is connected to the dust collection box 17 through the pipe. Example

[0031] A fiber leather composite heating device includes a housing 1. Two electric push rods 8, preferably of model THK, are bolted to the bottom sides of the inner wall of the housing 1. A housing 9 is bolted to the output ends of the four electric push rods 8. Multiple lower heating rollers 10 are mounted inside the housing 9 via bearings. When the four electric push rods 8 are activated, the output ends of the electric push rods 8 lift the housing 9, which in turn lifts the multiple lower heating rollers 10, causing the lower heating rollers 10 to lift the fiber leather, bringing the top of the fiber leather into contact with the upper heating roller 11. Multiple heat-absorbing covers 3, made of heat-insulating material, are bolted to the outer wall of one side of the top of the housing 1, with one end of each heat-absorbing cover extending into the interior of the housing 1. Upper heating rollers 10 are mounted inside the heat-absorbing covers 3 via bearings. The roller 11, upper heating roller 11, and lower heating roller 10 are preferably Herkules GTH-450 models. When the upper heating roller 11 and lower heating roller 10 are started, they will generate heat. After a period of preheating, the fiber leather that the upper heating roller 11 and lower heating roller 10 can contact will be heated. The upper heating roller 11 is located above the lower heating roller 10. Two air jet components 7 are installed inside the housing 1 by bolts. One air jet component 7 is facing downwards and the other air jet component 7 is facing upwards. Connecting pipes 2 are inserted into the outer wall of one side of the multiple heat absorption hoods 3. The connecting pipes 2 facilitate the connection of the air jet components 7 and the multiple heat absorption hoods 3 together. The two ends of the connecting pipes 2 extend into the two air jet components 7 respectively. Example

[0032] This embodiment further defines the features of Embodiment 1. Both sides of the outer wall of the housing 1 have inlets 5 for material entry and exit of the fiber leather. Multiple guide rollers 6 are mounted inside the housing 1 via bearings, facilitating the movement of the fiber leather within the housing 1. The air jet assembly 7 includes an air jet box 12. Two contacting fans 13 are bolted inside the air jet box 12. The fans 13 are preferably 9G0624P4H003 anti-splash axial flow fans. One end of the connecting pipe 2 extends into the air jet box 12. Multiple nozzles 15 are threadedly connected to the top of the air jet box 12. One side of the outer wall of the air jet box 12... Two heating tubes 14 are bolted on. The preferred model for heating tubes 14 is a 6200 infrared heating tube. Activating heating tubes 14 heats the air inside the air jet box 12. Activating the fan 13 inside the air jet box 12 and the heating tubes 14 causes the fan 13 to extract heat from the upper heating roller 11 inside the heat absorption hood 3 via the connecting pipe 2. The air then undergoes secondary heating via heating tubes 14 before being sprayed out through nozzles 15, preheating or reheating the top and bottom sides of the fiber leather. This achieves the utilization of preheating and the treatment of the fiber leather. The composite heating element of the casing 1 is as follows: A dust collection assembly 4 is bolted to one side of the outer wall of the casing 1. The dust collection assembly 4 includes a dust collection hood 16, which is bolted to the top side of the outer wall of the casing 1. The bottom end of the dust collection hood 16 extends into the interior of the casing 1. The bottom end of the dust collection hood 16 is opposite to the upward-facing jet assembly 7. A dust collection box 17 is bolted to one side of the outer wall of the casing 1. A dust discharge port is provided on one side of the outer wall of the dust collection box 17, and a connecting pipe 19 is inserted into the top of the dust collection box 17. One end of the connecting pipe 19 is connected to the dust collection hood 16. A dust pump 18 is bolted to the bottom side of the outer wall of the dust collection box 17. The dust pump 18 is of type 18. The preferred pump is an HG-120W / 220V (single-phase) vortex air pump. When the vacuum pump 18 is started, the vacuum pump 18 will create a negative pressure inside the dust collection box 17. Because the dust collection box 17 is under negative pressure, it will draw air from the inside of the vacuum hood 16 through the connecting pipe 19. Subsequently, the vacuum hood 16 will generate suction to adsorb dust and other impurities on the fiber leather, thus cleaning the fiber leather. At the same time, the upward-facing jet component 7 can remove dust from the fiber leather by jetting air. The two work together to clean both sides of the fiber leather. The vacuum pump 18 is connected to the dust collection box 17 through a pipe.

[0033] Working Principle: When using this device to heat fiber leather, the fiber leather can first be introduced into the housing 1 through the feed port 5, and then led out of the housing 1 through another feed port 5. Next, the upper heating roller 11 and lower heating roller 10 are started. The started upper heating roller 11 and lower heating roller 10 generate heat. After a period of preheating, the four electric push rods 8 are started. The output end of the electric push rods 8 will lift the housing 9, which in turn will lift multiple lower heating rollers 10, causing the lower heating rollers 10 to lift the fiber leather, so that the top of the fiber leather contacts the upper heating roller 11. Then, the traction device is started to wind up the fiber leather. During the winding process, the upper heating roller 11 and lower heating roller 10 will heat the fiber leather. During the heating process, the dust pump 18 can be started first, which will collect dust. The inside of the dust collection box 17 is under negative pressure. Because the inside of the dust collection box 17 is under negative pressure, the dust collection box 17 will draw air from the inside of the dust collection hood 16 through the connecting pipe 19. Then the dust collection hood 16 will generate suction to adsorb dust and other impurities on the fiber leather, thus cleaning the fiber leather. During the heating process, the fan 13 and heating tube 14 inside the air jet box 12 can be started. The started fan 13 will draw heat from the heat dissipation of the upper heating roller 11 inside the heat absorption hood 3 through the connecting pipe 2. The air carrying the heat will then be reheated by the heating tube 14 and then sprayed out through the nozzle 15 to preheat or reheat the top and bottom sides of the fiber leather, thus realizing the utilization of preheating and composite heating of the fiber leather. At the same time, the upward-facing air jet component 7 can remove dust from the fiber leather by air jetting.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
