Description

Technical Field

[0001] This utility model relates to the technical field of drying devices for imitation leather materials, and in particular to a drying device for a bacterial cellulose imitation leather material film. Background Technology

[0002] Proper drying can stabilize the properties of imitation leather films, such as maintaining good feel, strength, and elasticity, and preventing problems such as mold, deterioration, and adhesion caused by moisture or solvent residue, thereby improving product quality and service life. However, traditional methods of drying imitation leather films involve sandwiching two pieces of cardboard with leather texture between two wooden boards, binding and pressing the two wooden boards together, and then air-drying the imitation leather film between the two cardboard pieces. This method is slow, and the pressure decreases due to moisture evaporation and shrinkage during the drying process, making it impossible to maintain continuous pressure and thus reducing the quality of the imitation leather film. Therefore, we propose a drying device for bacterial cellulose imitation leather films. Utility Model Content

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Example 1: As Figure 1-5 As shown, a drying device for a bacterial cellulose imitation leather material film includes a drying chamber 1, a temperature control structure 6, and an extrusion board 5. A servo motor 2 is fixedly installed in the middle of the upper surface of the drying chamber 1. The output end of the servo motor 2 passes through a hole opened in the upper surface of the drying chamber 1 and is connected to a lead screw 3. An extrusion structure 4 is spirally installed on the surface of the lead screw 3. Guide slides 9 are fixedly installed near the four corners of the inner upper surface of the drying chamber 1. A diversion chamber 10 is fixedly installed on one side of the drying chamber 1. The temperature control structure 6 is installed on the side of the diversion chamber 10. A fan 7 is connected to the input end of the temperature control structure 6. A microcontroller control box 8 is installed near the front port of the upper surface of the drying chamber 1.

[0021] Both sides of the drying oven 1 are provided with guide holes 11. One side of the interior of the drying oven 1 is connected to the interior of the distribution chamber 10 through the guide holes 11, and the other side is connected to the outside through the guide holes 11 to discharge the evaporated moisture. The front port of the drying oven 1 is equipped with a heat preservation door 12 through a hinge. The guide holes 11 are used to disperse and discharge the airflow in the distribution chamber 10, so that hot airflow can pass through the evaporation holes 53 on each layer, thereby achieving the effect of uniform drying.

[0022] The extrusion structure 4 includes a guide plate 41, sliding holes 42, through holes 43, extrusion springs 44, pressure sensors 45, force-sharing plates 46, and limiting sliding columns 47. A threaded hole is provided in the middle of the guide plate 41, and the lead screw 3 is screwed to the guide plate 41 through the threaded hole. Sliding holes 42 are provided near the four corners of the surface of the guide plate 41, and through holes 43 are provided near the four corners of the surface of the guide plate 41. Extrusion springs 44 are fixedly installed on the lower surface of the guide plate 41 at the lower edge of the through holes 43. Pressure sensors 45 are fixedly installed on the lower surface of each extrusion spring 44. The lower surfaces of the four pressure sensors 45 are fixedly installed to the same force-sharing plate 46. When the power is on, the control can be achieved via the microcontroller on the control box 8. The control button controls the servo motor 2 to drive the lead screw 3 to rotate, thereby causing the guide plate 41 to move downward along the guide slide column 9. When the force plate 46 contacts the uppermost extruded cardboard 5, the extrusion spring 44 will be compressed and contracted. At this time, the limit slide column 47 will pass upward through the insertion hole 43. At the same time, because the pressure sensor 45 is under pressure, it converts the pressure it senses into an electrical signal and transmits it to the microcontroller control box 8, which displays it on its screen, allowing the operator to check the corresponding pressure in real time until the predetermined pressure value is reached and then stop controlling the servo motor 2. The limit slide column 47 is set to prevent the extrusion spring 44 from bending laterally when compressing it, and plays a guiding role for the extrusion spring 44.

[0023] The guide pin 9 slides through the sliding hole 42 to guide the guide plate 41; the guide pin 9 limits the guide plate 41 through the sliding hole 42, so that the guide plate 41 can only move downward or upward when the screw 3 rotates, thereby squeezing and releasing.

[0024] The extruded cardboard 5 includes a leather texture plate 51, a corrugated plate 52, and an evaporation hole 53. The leather texture plate 51 is fixedly installed on both the upper and lower surfaces of the corrugated plate 52, and the evaporation hole 53 is provided between the leather texture plate 51 and the corrugated plate 52. In use, multiple extruded cardboard 5s alternately press multiple imitation leather material films in the middle. The surface of the leather texture plate 51 has a texture, so after long-term pressing and drying, its texture will be imprinted on its surface. During drying, the moisture of the imitation leather material film is absorbed through the leather texture plate 51 and then evaporated and carried away by the heated gas flowing through the evaporation hole 53.

[0025] The temperature control structure 6 includes a temperature controller 61, a temperature sensor 62, and an electric heating mechanism 63. The temperature controller 61 is fixedly installed on the upper surface of the drying oven 1. The temperature sensor 62 is embedded inside the distribution cavity 10. The output end of the electric heating mechanism 63 is connected to the distribution cavity 10 through a flow guide channel. The output end of the fan 7 is connected to the input end of the electric heating mechanism 63. The temperature sensor 62 is electrically connected to both the temperature sensor 62 and the electric heating mechanism 63 through wires. The fan 7 is powered by a microcontroller in the microcontroller control box 8. Both the temperature controller 61 and the microcontroller control box 8 are connected to the mains power supply through wires. The servo motor 2 is controlled by the microcontroller in the microcontroller control box 8 via a wire. When the power is turned on, the microcontroller control box 8 immediately supplies power to the fan 7 to run. At the same time, the mains power also supplies power to the temperature controller 61. Then, the upper and lower limit temperature ranges of the temperature control are set through the temperature controller 61. The temperature sensor 62 monitors the air temperature in the distribution chamber 10 and feeds it back to the temperature controller 61 in real time. The temperature controller 61 controls whether to supply power to the electric heating mechanism 63 for heating based on the temperature. When the temperature is lower than the lower limit temperature, the electric heating mechanism 63 is supplied with power for heating. When the temperature is higher than or equal to the upper limit temperature, the electric heating mechanism 63 is stopped from supplying power for heating.

[0026] It should be noted that this utility model is a drying device for a bacterial cellulose imitation leather material film. In use, the insulated door 12 is opened, and the alternately stacked extruded cardboard 5 and imitation leather material film are placed inside the drying chamber 1. The insulated door 12 is then closed. The temperature control structure 6 controls the servo motor 2 to drive the lead screw 3, causing the guide plate 41 to move downwards. When the pressure plate 46 begins to press the uppermost extruded cardboard 5, the pressure sensor 45 senses the pressure and displays the pressure value on the display screen of the microcontroller control box 8 via wires for the user to view. The pressure is adjusted to a suitable level and then stopped. The temperature control structure 6 is then activated, and the fan... The machine 7 introduces outside air, and the electric heating mechanism 63 heats the airflow and pours it into the distribution chamber 10. At the same time, the temperature sensor 62 monitors the internal temperature of the distribution chamber 10 in real time to ensure that the temperature is suitable. At this time, the airflow is distributed to the drying chamber 1 through the guide hole 11. Then, the airflow carries away the moisture absorbed by the leather texture plate 51 through the evaporation hole 53 and is discharged out through the guide hole 11 on the other side. During this period, if the shrinkage pressure of the imitation leather material film decreases due to drying, the servo motor 2 can be adjusted to make the force plate 46 press down to reach the predetermined pressure value. The pressure sensor 45 is model N10A and the temperature controller 61 is model XMT-101.
