Description
Technical Field
[0001] The utility model belongs to the technical field of drive devices, and specifically relates to an energy-saving drive device based on automatic control. Background Art
[0002] Electric sieves are easy to use, simple to operate, high screening efficiency, accurate screening results, etc., so they are widely used in chemical, food, medicine, metallurgy, mining, construction and other fields. For example, in the chemical field, electric sieves are used to separate materials such as powders, particles and liquids; in the food field, electric sieves are used to separate flour, starch, sauces, etc.; in the pharmaceutical field, electric sieves are used to screen medicinal materials, pharmaceutical raw materials and medicines.
[0003] The electric screen mainly uses a motor and a crankshaft to drive the screen on the steel frame to move back and forth in a straight line. In this way, after the material is placed on it, it will continue to shake, and use inertia to separate debris, sand, gravel and other debris in the material.
[0004] When screening garlic in a food factory, a single-chip microcomputer is used to control the motor, which automatically drives the crankshaft to drive the screen to reciprocate in a straight line. However, there is often an interval when garlic is bagged. During this interval, the electric screen continues to operate, causing the electric screen to waste electricity during the garlic feeding interval, resulting in poor energy saving during the garlic feeding interval when driving the electric screen. For this reason, we propose an energy-saving drive device based on automatic control. Utility Model Content
[0005] The purpose of the utility model is to provide an energy-saving driving device based on automatic control, which can detect the feeding interval, and the controller automatically controls the servo motor to stop during the feeding interval, so as to improve the energy saving performance during the garlic feeding interval in the process of driving the electric sieve.
[0006] The technical solutions adopted in this utility are as follows:
[0007] An energy-saving driving device based on automatic control comprises two steel frames and a servo motor arranged between the two steel frames, and also comprises a controller fixedly connected to any one of the steel frames. The interval between the two steel frames forms a motion channel. The two ends of the motion channel are respectively used for loading and unloading and are respectively fixed with two button switches and displacement sensors. A material guide plate is arranged at a position above the two button switches at the loading end of the motion channel. The servo motor, the two button switches and the two displacement sensors are all connected to the controller signal. When driving the electric sieve, the bags of garlic are poured into the motion channel in batches along the material guide plate. The garlic is pressed down to guide the material. One side of the plate flips down, and the guide plate presses the button switch, sending a start signal to the controller along the signal repeater, controlling the servo motor to pull the screen to move back and forth in the motion channel to shake the garlic, and the garlic slowly rolls down from the unloading end of the motion channel, and the unloading signal is detected by two displacement sensors until all the garlic is unloaded. If the two displacement sensors do not detect the unloading signal within the specified time period after the button switch is triggered by the start signal, it means that it is in the garlic feeding interval. The controller can automatically control the servo motor to stop in the garlic feeding interval to improve the energy saving in the garlic feeding interval during the driving of the electric sieve.
[0008] The two steel frames are fixed with bearing seats on the sides away from each other, and the two bearing seats are rotatably connected to the two sides of the guide plate on the sides close to each other, supporting the guide plate from two points so that it is suspended above the two button switches. After being pressed down, it can swing downward in a coaxial unidirectional manner around the two bearing seats, and can be pressed down to trigger the button switch. The guide plate itself can be made of aluminum alloy or plastic, which is light in weight and will not trigger the button switch when pressed down alone.
[0009] Elastic pads are fixed on the upper surfaces of the two steel frames near the feeding end of the moving channel. The elastic pads may be rubber columns with annular, porous, honeycomb or other structures, which are slightly higher than the button switch, so that the guide plate can be supported before the button switch, so that the guide plate will not touch the button switch when it is suspended in the air, thereby avoiding accidental touch of the two. When the garlic presses down on the guide plate, the elastic pad will be deformed, causing the guide plate to swing down and trigger the button switch. After the guide plate is unloaded, the elastic pad restores its shape, which can push the guide plate to swing up and disengage from the button switch.
[0010] A limiting block is provided on one side of the two button switches away from the elastic pad. The two limiting blocks are fixedly connected to the adjacent steel frames. After the guide plate swings down a certain distance, it abuts against the limiting block and is limited to avoid excessive squeezing of the button switch.
[0011] Ceramic plates are fixed on both edges of the guide plate. The two ceramic plates are respectively vertically facing the two button switches. The guide plate uses the smooth surface of the ceramic plate to contact the button switch to reduce friction, wear the ceramic plate first, and scrap the ceramic plate first during maintenance.
[0012] Above both of the two displacement sensors, there are shielding covers. The two sides of the two shielding covers are respectively folded down along the two sides of the adjacent displacement sensors and are fixedly connected to the adjacent steel frames, shielding the dust falling from above, which can play a certain dust-proof role and is beneficial to improving the accuracy of the beam-to-beam detection of displacement by the two displacement sensors.
[0013] The technical effects achieved by this utility model are as follows:
[0014] In a kind of energy-saving driving device based on automatic control of this utility model, when driving an electric sieve, pour the bagged garlic onto the movement channel in batches along the guide plate. These garlic press down one side of the guide plate and turn it down, and the guide plate presses the push button switch, and sends a start signal to the controller along the signal repeater, controlling the servo motor to pull the sieve net to move left and right reciprocally in the movement channel to shake the garlic. And the garlic slowly rolls down from the discharging end of the movement channel and is detected by the two displacement sensors for the discharging signal. Until all the garlic is discharged, if the two displacement sensors do not detect the discharging signal within the specified time period after the push button switch is triggered by the start signal, it means that it is in the garlic feeding interval, and the controller can automatically control the servo motor to stop running during the garlic feeding interval, so as to improve the energy saving during the process of driving the electric sieve in the garlic feeding interval.

[0022] In order to make the purpose and advantages of the present utility model clearer and more understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection of the specific claims of the present utility model.
[0023] As Figures 1-5 shown, an energy-saving drive device based on automatic control includes two steel frames 1 and a servo motor 2 disposed between the two steel frames 1. It also includes a controller 3 fixedly connected to any one of the steel frames 1. The controller 3 can be a Mitsubishi series single-chip microcomputer purchased from the market. The interval between the two steel frames 1 forms a movement channel. The two ends of the movement channel are respectively used for feeding and discharging materials, and are respectively fixed with two push-button switches 4 and displacement sensors 6. High-head push-buttons of the HBDGQ10 / HBDGQ12 model purchased from the market can be selected, with an IP40 protection level, a brass-nickel-plated housing, corrosion-resistant, pressure-resistant, and wear-resistant. A guide plate 5 is provided at the position above the two push-button switches 4 at the feeding end of the movement channel. The servo motor 2, the two push-button switches 4, and the two displacement sensors 6 are all signal-connected to the controller 3. 7. The feeding end of the movement channel is placed obliquely upward on the ground. When driving the electric sieve, the bagged garlic is poured in batches along the guide plate 5 onto the movement channel. These garlics press down the guide plate 5 and turn it over while sliding down onto the sieve mesh. And the guide plate 5 presses down the push-button switch 4, and sends a start signal to the controller 3 along the signal repeater, controlling the servo motor 2 to rotate forward to drive the crankshaft and several articulated rods to pull the sieve mesh to reciprocate left and right in the movement channel to shake the garlic, and under the action of inertia, the soil residues and other impurities are shaken off, while the garlic slowly rolls down from the discharging end of the movement channel and is detected by the two displacement sensors 6 for the discharging signal until all the garlic is discharged. If the two displacement sensors 6 do not detect the discharging signal within a specified time period after the push-button switch 4 is triggered by the start signal, it means that it is in the garlic feeding interval, and the controller 3 can automatically control the servo motor 2 to stop running during the garlic feeding interval, so as to improve the energy saving during the process of driving the electric sieve in the garlic feeding interval.
[0024] As Figure 5 shown, the controller 3 is equipped with a control system, which can be called by those skilled in the art by writing a program into a storage medium. It can generally be implemented independently, so it is not necessary to write it out.
[0025] As Figure 1 and Figure 2 shown, bearing seats 7 are fixedly provided on the sides of the two steel frames 1 away from each other. The sides of the two bearing seats 7 close to each other are respectively rotatably connected to both sides of the guide plate 5, supporting the guide plate 5 from two points so that it is suspended above the two push-button switches 4. After being pressed down, it can swing downward unidirectionally around the coaxial axis of the two bearing seats 7 and can press down and trigger the push-button switch 4. The guide plate 5 itself can be made of aluminum alloy or plastic, with a small weight, and pressing it alone will not trigger the push-button switch 4.
[0026] like Figure 1 and Figure 2 As shown, elastic pads 8 are fixed on the upper surfaces of the two steel frames 1 near the feeding end of the motion channel. The elastic pads 8 can be rubber columns with annular, porous, honeycomb or other structures, which are slightly higher than the button switch 4, so that the guide plate 5 can be supported before the button switch 4, so that the guide plate 5 will not contact the button switch 4 when it is suspended in the air, avoiding accidental contact between the two. When the garlic presses down on the guide plate 5, the elastic pad 8 will be deformed, causing the guide plate 5 to swing down and trigger the button switch 4. After the guide plate 5 is unloaded, the elastic pad 8 restores its shape and can push the guide plate 5 to swing up and disengage from the button switch 4.
[0027] like Figure 1 and Figure 2 As shown, a limit block 9 is provided on one side of the two button switches 4 away from the elastic pad 8, and the two limit blocks 9 are fixedly connected to the adjacent steel frame 1. After the guide plate 5 swings down a certain distance, it abuts against the limit block 9 and is limited to avoid excessive squeezing of the button switch 4.
[0028] like Figure 1 and Figure 3 As shown, ceramic plates 10 are fixed on both edges of the guide plate 5. The two ceramic plates 10 are respectively vertically facing the two button switches 4. The guide plate 5 uses the smooth surface of the ceramic plates 10 to contact the button switches 4 to reduce friction and give priority to wearing the ceramic plates 10. The ceramic plates 10 are scrapped first during maintenance.
[0029] like Figure 2 and Figure 4 As shown, a shielding cover 11 is provided above the two displacement sensors 6. The two sides of the two shielding covers 11 are folded downward along the two sides of the adjacent displacement sensors 6 and are fixedly connected to the adjacent steel frames 1 to block the dust falling from above. It can play a certain dust-proof role and is beneficial to improve the accuracy of the two displacement sensors 6 in detecting displacement by the light beams.
[0030] The working principle of the utility model is as follows: when the electric sieve is driven, bags of garlic are poured into the motion channel in batches along the guide plate 5, the garlic presses down the guide plate 5 and turns down, slides onto the screen, and the guide plate 5 presses down the button switch 4, sends a start signal to the controller 3 along the signal repeater, controls the servo motor 2 to rotate forward, drives the crankshaft and a plurality of articulated rods to pull the screen to reciprocate left and right in the motion channel, so as to shake the garlic and throw off impurities such as soil residue under the action of inertia.
[0031] The garlic slowly rolls downward from the unloading end of the motion channel, and unloading signals are detected by two displacement sensors 6 until all the garlic is unloaded.
[0032] If the two displacement sensors 6 do not detect the blanking signal within the specified time period after the button switch 4 is triggered to start the signal, it indicates that it is in the garlic feeding interval. The controller 3 can automatically control the servo motor 2 to stop during the garlic feeding interval, so as to improve the energy saving performance of the process of driving the electric sieve during the garlic feeding interval.
[0033] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in this field without special explanation and limitation.
