DETAILED DESCRIPTION

[0024] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] Example 1

[0027] A piano cover drying device for preventing deformation, such as Figure 1 , Figure 2 As shown, the drying device includes a base 1, a shell 2, a door 3, a return air device 1 4, a return air device 2 10, a fan 8, a dryer 1 9, and a dryer 2 14; the door 3 is mounted on the shell 2 by hinges; the return air device 1 4 and the return air device 2 9 are mounted on the door 3 by bolts, the dryer 1 9 is fixed to the top inner side of the shell 2 by bolts, the dryer 2 14 is fixed to the bottom inner side of the shell 2 by bolts, the fan 8 is mounted on the rear inner side of the shell 2 by bolts, and the fan 8 is mounted at the same horizontal position as the return air device 1 4 and the return air device 2 9; as shown Figure 4 As shown, the structures of the return air unit 1 4 and the return air unit 2 10 are bulged upward in the center, forming a semi-annular cavity at the bottom of the return air unit 1 4 and the return air unit 2 10 .

[0028] In this case, when the drying device is working, the operator closes the door 3, and the return air device 1 4 and the return air device 2 10 form a return air mechanism to form an annular cavity at the bottom. When the dryer is working, the dryer 1 9 and the dryer 2 14 start to heat up, so that the temperature inside the drying device increases, and the fan 8 starts to run, blowing air into the drying device to make the air flow and dry the piano cover as a whole. As the fan 8 runs, the hot air will be blown onto the door 3. Because the return air device 1 4 and the return air device 2 10 are installed on the door 3, the hot air will be gathered in the cavity and the gathered hot air will be returned along the original route. The gathered hot air collides with the wind blown in by the fan 8, driving the internal circulation of the drying device, so that the drying device can evenly heat the piano cover.

[0029] like Figure 1 As shown, the drying device also includes an electric lock 5, a control panel 6, and a glass window 7. The control panel 6 is installed on one side of the outer shell 2; the electric lock 5 is installed on the door 3 by bolts, and the electric lock 5 and the control panel 6 are electrically connected; the glass window 7 is installed on one side of the outer shell 2, side by side with the control panel.

[0030] In this case, workers can control the opening and closing of the electric lock 5 through the control panel 6. When the drying device is working, extremely high heat is accumulated inside the dryer. If the door 3 is opened rashly, the heat will erupt instantly and burn the operator. When the temperature inside the drying device does not reach the safe temperature, the operation panel 6 will lock the electric lock 5 until it reaches the appropriate temperature. The control panel 6 transmits a signal to the electric lock 6 to adjust the safety lock 6 to the unlocking mode. The user then opens the door 3. When the drying device is working, the operator can observe the situation inside the drying device through the glass window.

[0031] In order to solve the problem of how to control the internal temperature of the drying device; Figure 2 As shown, the drying device also includes a temperature sensor 11, which is installed on the inner side of the housing 2 by bolts. The temperature sensor 11 is electrically connected to the control panel 6, and the control panel 6 controls the operation of the dryer 1 9 and the dryer 2 14 based on the signal of the temperature sensor 11.

[0032] In this case, by installing the temperature sensor 11, the temperature inside the drying device can be monitored in real time. The operator can check the temperature inside the drying device through the operation panel 6. At the same time, the operation panel of the drying device can pre-install the drying conditions of the corresponding piano cover wood. It only needs to select the preset program to automatically heat up. The temperature can be dynamically adjusted by the temperature sensor 11 to realize intelligent drying and avoid the piano cover from cracking due to excessive temperature.

[0033] In order to solve the problem of how to adjust the wind force; Figure 2 As shown, the drying device further includes a wind sensor 15 , which is installed on the inner side of the housing 2 by bolts. The wind sensor 15 is electrically connected to the control panel 6 , and the control panel 6 controls the operation of the fan 8 based on the signal of the wind sensor 15 .

[0034] In this case, the wind sensor 15 detects the wind force inside the drying device and transmits the detection data to the control panel 6. The control panel 6 appropriately controls the motor speed of the fan 8 according to the preset conditions, thereby adjusting the air flow inside the dryer.

[0035] In order to solve the problem of material in and out; Figure 1 , Figure 3As shown, the drying device also includes a limiter 12, a ball screw 13, a ball nut 17, a stepper motor 19, a stop plate 16, and a conduit 20. The conduit 20 is horizontally installed on the inner side of the shell 2 by bolts, the limiter 12 is fixed in front of the conduit 20 by bolts, the ball screw 13 is installed inside the conduit, the ball nut 17 is sleeved on the ball screw 13, the output end of the stepper motor 19 is connected to the tail of the ball screw 13 through a coupling, the stepper motor 19 is fixed to the inner side of the shell by bolts, the stop plate 16 is fixed to the ball nut 17 by bolts, and there is a steel pipe in the middle of the stop plate, and the steel pipe is welded to the side wall of the stop plate, leaving gaps between the steel pipes.

[0036] In this case, the operator places the piano cover on the stop plate and presses a button on the control panel 6. The control panel 6 starts the stepper motor 19 through an electrical signal. The stepper motor 19 controls the ball screw 13 to transport the piano cover to the inside of the drying device. After drying, the control panel 6 transmits an electrical signal to the stepper motor 19 according to a preset program to control the stepper motor 19 to transport the piano cover out of the drying device after drying, thereby avoiding the workers from manually pulling out the stop plate 16 from the previous machine, reducing the workload and preventing the workers from being burned by high temperature.

[0037] The working principle and use process of the utility model are as follows: the operator places the piano cover to be dried on the stop plate 16, and then starts the stepper motor 19 on the control panel 6 to transport the piano cover to the inside of the drying device. The operator adjusts the preset content on the control panel 6, and then clicks the start heating button, and the dryer 1 9 and the dryer 2 14 start to heat. As the temperature inside the drying device increases, when it reaches the preset temperature, the control panel 6 controls the fan 8 to start. During drying, the control panel 6 adjusts the speed of the fan 8 in real time according to the preset content through the data of the temperature sensor 11 and the wind sensor 15, and adjusts the power of the dryer 1 9 and the dryer 2 14. According to the preset conditions, after baking is completed, the control panel 6 controls the dryer 1 9 and the dryer 2 14 to stop heating, senses the temperature inside the drying device through the temperature sensor 11, and uses the fan 8 to cool down the inside of the device. After reaching a safe temperature, the control panel 6 controls the electric lock to unlock, and after the operator opens the door 3, controls the stepper motor 19 to push the ball screw 13 to transport the piano cover out of the drying device.
