Description

Technical Field

[0001] The present application relates to the technical field of planing machines, and in particular to an energy-saving and noise-reducing planing machine. Background Art

[0002] Planers are indispensable tools for wood processing and are widely used in house construction, housing decoration, woodworking workshops, field woodworking operations, and vehicle, ship, and bridge construction to perform operations such as planing, chamfering, and cutting of various woods.

[0003] In the prior art, a planer using a series-excited motor is generally used. This planer has the advantages of high production efficiency and a flat and smooth planed surface. However, since the motor speed of the planer is as high as more than 20,000 in the working state (including no-load state and load planing state), the noise generated by the planer will exceed 95dB, causing many troubles to the users. On the one hand, the noise far exceeds the national environmental sound emission standards, causing great noise distress to the users and greatly reducing the comfort of use. On the other hand, in the no-load state, the high-speed running motor will further cause energy waste, poor energy saving and environmental protection, and greatly reduced practicality.

[0004] Therefore, there is an urgent need for a planing machine that saves energy and reduces noise. Utility Model Content

[0005] The purpose of the present application is to provide an energy-saving and noise-reducing planer to solve the problems existing in the prior art, such as low comfort level in use, poor energy conservation and environmental protection, and the need for further improvement in practicality of the planer.

[0006] The embodiments of the present application can be implemented through the following technical solutions:

[0012] Furthermore, the photoelectric emitting end and the photoelectric receiving end of the laser beam sensing switch are arranged on two sides of the planer body facing each other.

[0013] Furthermore, a second position detection sensor is provided at the outlet end of the planer body, and the second position detection sensor is electrically connected to the controller.

[0020] The energy-saving and noise-reducing planer provided by the embodiment of the present application has at least the following beneficial effects:

[0021] The planer in the present application works in two states during use, one is a no-load noise reduction state, and the other is a load planing state. It continuously cycles between the no-load state and the load state, and the usage ratio of the no-load state and the load state is basically 50% each.

[0031] Figure 1 , Figure 2 They are schematic diagrams of the structure of an energy-saving and noise-reducing planer in the present application at different viewing angles, such as Figure 1 , Figure 2 As shown, an energy-saving and noise-reducing planer includes a base 1, a frame 2, and a planer body 3. The base 1 and the frame 2 are matched and connected to form a shell with an accommodating space inside. The planer body 3 is connected to the shell. A lifting seat 8 is provided above the base 1. A pointer 9 is provided on one side of the lifting seat 8. The pointer 9 points to a scale 10 on the right side cover of the frame 2, so as to find the feeding height of the inlet end of the planer body 3.

[0032] An inlet of the planer body 3 is provided between the base 1 and the lifting seat 8. Along the feeding and discharging direction of the planer body 3, a first position detection sensor 6 is provided at the inlet end of the planer body 3 for detecting the position of the wood.

[0033] In some preferred embodiments, in order to increase the accuracy of position detection during wood planing, a second position detection sensor 7 may also be provided at the outlet end of the planer body 3 to detect whether the wood is removed through the outlet end of the planer body 3.

[0034] In some preferred embodiments, the first position detection sensor 6 and the second position detection sensor 7 may be mechanical contact switches, photoelectric diffuse reflection induction switches, or laser beam induction switches.

[0035] In some preferred embodiments, the mechanical contact switch is a pressure sensor, the sensing element of the pressure sensor is a pressure sensitive element, and the pressure sensitive element is arranged at the entrance between the base 1 and the lifting seat 8.

[0036] In some preferred embodiments, when the first position detection sensor 6 and the second position detection sensor 7 are photoelectric diffuse reflection induction switches, the photoelectric emitting end and the photoelectric receiving end of the photoelectric diffuse reflection induction switch are arranged opposite to each other at the upper and lower parts of the entrance between the base 1 and the lifting seat 8.

[0037] In some preferred embodiments, when the first position detection sensor 6 and the second position detection sensor 7 are laser beam sensing switches, the photoelectric emitting end and the photoelectric receiving end of the laser beam sensing switch are arranged on opposite sides of the planer body 3 .

[0038] Furthermore, the planer body 3 is provided with a controller connected to its motor, and the first position detection sensor 6 and the second position detection sensor 7 are both electrically connected to the controller and send detection signals to the controller respectively. The controller controls the motor of the planer body 3 to reduce speed by reducing voltage or frequency modulation according to the detection signals sent by each position detection sensor, so that when any position detection sensor recognizes the material, the motor of the planer body 3 is in a high-speed operation state. Only when the two position detection sensors cannot recognize the material, the motor of the planer body 3 is in a reduced speed state, ensuring that the planer body 3 is judged as an unloaded state when there is no wood put in, that is, when the sensor cannot detect the wood, the controller sets the motor speed to 50% speed, thereby reducing noise. When the wood passes through and the sensor detects the wood, it is judged as a loaded state. At this time, the controller inside the machine sets the motor speed to 100% speed until the wood is completely discharged through the planer body 3, and then the motor speed is reduced to 50% through the controller to enter the noise reduction mode.

[0039] In some preferred embodiments, the controller includes a control circuit such as Figure 3 As shown, the control circuit includes an input terminal L pole, an input terminal N pole, an output terminal positive pole, and an output terminal negative pole. The input terminal L pole of the control circuit is connected to the L pole of the power supply, and the output terminal positive pole is connected to the positive pole of the motor of the planer body 3;

[0040] The N pole of the input terminal of the control circuit is connected to the N pole of the power supply, and the negative pole of the output terminal is connected to the negative pole of the motor of the planer body 3.

[0041] In some preferred embodiments, a delay circuit module is provided in the control circuit, and the first position detection sensor 6 is electrically connected to the control module through the delay circuit module, and the delay circuit module is used to generate a base delay time signal and a peak delay time signal and output them to the control module, so that when the motor of the planer body 3 is in a load state, when the first position detection sensor 6 sends a material removal signal to the controller, under the action of the delay circuit module of the controller, the controller will not immediately send a stop command to the motor of the planer body 3, but will maintain the motor speed at 100% after a set period of time, until the wood is completely discharged from the planer body 3, and then the motor speed will be reduced to 50% through the controller to enter the noise reduction mode to avoid material jamming in the planer body 3.

[0042] In some preferred embodiments, the delay circuit module is a delay circuit with 555IC as the core, including a base delay circuit, a peak delay circuit, a base delay potentiometer and a peak delay potentiometer. The base delay potentiometer and the peak delay potentiometer respectively adjust the length of the base delay time and the peak delay time, and the base delay time and the peak delay time are switched with each other.

[0043] In some preferred embodiments, a switch 30 is connected to the planer body 3, and the switch 30 is electrically connected to the controller, so that the machine can be switched between the noise reduction mode and the normal working mode.

[0044] In some preferred embodiments, the inlet end and the outlet end of the base 1 are respectively connected to the first support plate 4 and the second support plate 5. In the working state, the first support plate 4 and the second support plate 5 extend outward along the feeding and discharging direction of the planer body 3 to support the wood and provide supporting force for the wood.

[0045] The above is a detailed introduction to the specific implementation methods of the present application. For those skilled in the art, several improvements and modifications may be made to the present application without departing from the principles of the present application. These improvements and modifications also fall within the scope of protection of the claims of the present application.
