Description

Technical Field

[0001] This utility model belongs to the field of vibratory machines, and in particular relates to a vibratory machine with a soundproof cover and a dehumidification function. Background Technology

[0002] A vibratory mill is a common piece of equipment used for grinding workpieces. The existing structure of a vibratory mill includes a tubular casing, a vibratory disc inside the casing, a discharge port at the top of the vibratory disc, and a spiral grinding groove on the top surface of the vibratory disc. The vibratory disc is located at the top of the casing, and a support frame connects it to the casing below. Multiple springs connect the vibratory disc to the support frame. A vibrating mechanism is located at the bottom of the grinding groove. When the vibrating motor in the vibrating mechanism rotates forward, the material spirals and rises along the grinding groove, i.e., it rises, entering the grinding working state. When one cycle is completed, the vibrating motor in the vibrating mechanism reverses, and the material spirals down along the grinding groove, i.e., it recedes. A sorting sieve plate for separating abrasive particles and workpieces is located at the discharge port. The sorting sieve plate extends to the upper end of the grinding groove, and a discharge plate connecting the vibratory disc is located between the sorting sieve plate and the grinding groove. When the discharge plate is lowered, it connects the sorting sieve plate and the grinding groove.

[0003] The existing method of using a vibratory mill is as follows: In the initial state, the discharge plate flips upward, separating the upper end of the grinding tank from the sorting screen plate. Abrasive grains and workpieces are placed in the grinding tank, and grinding water and grinding aids are added. The vibratory motor is started to rotate forward. Under the action of the vibration mechanism, the abrasive grains and workpieces roll and climb inward along the grinding tank (i.e., rising tide), and then fall back from the upper end of the grinding tank to the lower end. This cycle continues until the workpiece is ground to the required standard. At this point, some material will accumulate at the high position of the grinding tank, preventing the discharge plate from being lowered. Therefore, the vibratory motor needs to be started to rotate in reverse to allow the material to recede to one end, exposing the high position of the grinding tank. With no material, the discharge plate can be lowered. After the discharge plate is lowered, the vibratory motor is started to rotate forward again. The material rises and passes through the sorting screen plate, where the abrasive grains and workpieces are separated. The abrasive grains fall back into the grinding tank, and the workpieces are discharged from the discharge port.

[0004] The drawbacks of existing vibratory mills are that the discharge plate is manually operated, which is not conducive to automated control, and a lot of noise is generated during the grinding process. Utility Model Content

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0028] Example 1. A vibratory machine with a soundproof cover and dehumidification function, such as... Figure 1 and Figure 2 As shown, the device includes a tubular housing 1, inside which is a grinding container 2. The grinding container 2 has an annular thin-walled structure. A discharge port 3 is located at the top of the grinding container 2. A spiral grinding groove 4 is located on the top surface of the grinding container 2, with a spiral angle slightly less than 360°. The upper and lower ends of the grinding groove 4 are connected by inclined surfaces. A PU covering layer is provided on the inner wall of the grinding groove 4. A support 5 connecting the grinding container 2 to the housing 1 is located below the grinding container 2. Multiple springs 6 are located between the grinding container 2 and the support 5. A vibration mechanism 7 is located at the bottom of the grinding groove 4. A grid plate 8 is located at the discharge port 3, extending towards the upper end of the grinding groove 4. A discharge plate 9 is located between the grid plate 8 and the grinding groove 4. Its features are as follows:

[0029] The discharge plate 9 is provided with a rotating shaft 10 connected to the grinding container 2 on the side near the sorting screen plate 8. One end of the rotating shaft 10 extends out of the grinding container 2 and is provided with a swing rod 11. The end of the swing rod 11 is provided with a first cylinder 12. The output end of the first cylinder 12 is hinged to the swing rod 11, and the cylinder body of the first cylinder 12 is hinged to the outer wall of the grinding container 2.

[0030] The discharge plate 9 is provided with a regular hexagonal prism-shaped through hole 13. The rotating shaft 10 passes through the through hole 13. The part of the rotating shaft 10 inside the through hole 13 is a regular hexagonal prism that matches the through hole 13. Both ends of the rotating shaft 10 are connected to the grinding container 2 through a seated bearing 14. The seated bearing 14 is located on the outside of the grinding container 2.

[0031] The swing arm 11 is threadedly connected to the rotating shaft 10. The swing arm 11 is provided with a groove 15. The inner end of the groove 15 extends to the rotating shaft 10. Two open clamping plates 16 are formed on both sides of the groove 15. A locking screw 17 is provided between the two open clamping plates 16.

[0032] The top of the housing 1 is provided with a soundproof cover 18, and the outer side of the housing 1 is provided with a support column 19. The lower end of the support column 19 is provided with a base 20 connected to the housing 1. The upper end of the support column 19 is hinged to one side of the soundproof cover 18. A second cylinder 21 is provided between the support column 19 and the housing 1. The cylinder body of the second cylinder 21 is hinged to the base 20, and the output end of the second cylinder 21 is hinged to the soundproof cover 18.

[0033] Preferably, a self-locking device 23 can be provided between the silencing cover 18 and the support column 19. The self-locking device 23 is connected to the outer wall of the support column 19. The self-locking device consists of a limit switch and an electric push rod. The electric push rod is connected to the PLC controller 27 through the limit switch. When the silencing cover 18 is opened to the correct position, the silencing cover 18 contacts the detection end of the limit switch. The limit switch sends a signal to the PLC controller 27, and the PLC controller 27 causes the electric push rod to extend and insert into the positioning hole at the rear of the silencing cover 18, locking the silencing cover 18.

[0034] Preferably, a buffer device 22 can be provided between the muffler 18 and the base 20. The buffer device 22 can be a hydraulic rod, with the upper and lower ends of the hydraulic rod hinged to the muffler 18 and the base 20 respectively, to prevent violent collisions caused by the muffler 18 opening and closing too quickly.

[0035] The inner side of the soundproof cover 18 and the inner wall of the housing 1 are both provided with soundproofing cotton.

[0036] A drain valve 25 is provided at the lowest point of the grinding tank 4. Opening the drain valve 25 can discharge grinding wastewater. Preferably, a filter screen for intercepting abrasive particles can be installed at the outlet of the drain valve 25.

[0037] Working principle: The movement of the discharge plate 9 is achieved by the first cylinder 12. When the first cylinder 12 extends, it pushes the swing arm 11, which drives the discharge plate 9 to rotate upward, preventing material from entering the sorting screen plate 8. The abrasive particles and workpieces continue to circulate in the grinding tank 4, with the workpieces continuously circulating. When the first cylinder 12 retracts, the discharge plate 9 rotates downward, and the material enters the discharge plate 9 from the upper end of the grinding tank 4. The workpieces are separated from the abrasive particles at the sorting screen plate 8, and the workpieces are discharged from the discharge port 3. To adjust the rotation position of the discharge plate 9, loosen the locking screw 17 and rotate the discharge plate 9 to the corresponding angle. At this time, the rotating shaft 10 will move axially a very small distance relative to the swing arm 11. Then tighten the locking screw 17. Adjustment is convenient.

[0038] When grinding the workpiece, the second cylinder 21 is in the retracted state, which closes the muffler 18 and reduces noise. In other states, the second cylinder 21 is in the extended state, which opens the muffler 18.

[0039] The remaining parts operate in the same way as existing vibratory machines.

[0040] Example 2. Based on Example 1, a control cabinet 26 is provided on the outside of the housing 1. The control cabinet 26 is equipped with a PLC controller 27 (a full-function flexible programmable controller, model XD3-16R-E, and an industrial touch screen based on an intelligent operating system, model TGA63S-MT). The first cylinder 12 is connected to the air source through the first solenoid valve 29, and the second cylinder 21 is connected to the air source through the second solenoid valve 30. The first solenoid valve 29, the second solenoid valve 30, the drain valve 25, and the vibration mechanism 7 are all connected to the PLC controller 27. A flow pump 28 and a metering pump 31 are connected to the PLC controller 27. The outlets of the flow pump 28 and the metering pump 31 both pass through the housing 1 and are connected to the grinding tank 4.

[0041] The working principle of Example 2 is as follows: First, the material and workpiece are placed into the grinding tank 4, and then the following actions are sequentially performed by the built-in program of the PLC controller:

[0042] 1) The PLC controller 27 extends the first cylinder 12 via the first solenoid valve 29, causing the discharge plate 9 to rotate upwards.

[0043] 2) The PLC controller 27 causes the second cylinder 21 to retract via the second solenoid valve 30, and the silencer 18 closes onto the housing 1, entering the closed state.

[0044] 3) The PLC controller 27 adds a certain amount of grinding water to the grinding tank 4 through the flow pump 28, and the PLC controller 27 adds a certain amount of grinding aid to the grinding tank 4 through the metering pump 31.

[0045] 4) PLC controller 27 starts the vibrator to rotate forward, and the material rolls inward in a humid state, circulating in the grinding tank 4. After a period of time, the workpiece grinding is completed, and PLC controller 27 starts the vibrator to rotate in reverse, and the material is dehumidified and collects at the bottom of the grinding tank 4, so that the high part of the grinding tank 4 is covered with material.

[0046] 5) The PLC controller 27 causes the first cylinder 12 to retract through the first solenoid valve 29, and the discharge plate 9 rotates downward. One end of the discharge plate 9 is aligned with the high position of the grinding tank 4, and the material can reach the sorting screen plate 8 from the discharge plate 9.

[0047] 6) When the PLC controller 27 starts the vibration motor to rotate forward, the material rolls inward and rises to a high tide state. The material arrives at the sorting screen plate 8, and the workpiece passes smoothly through the sorting screen plate 8. The abrasive particles and grinding water fall back into the grinding tank 4 through the holes of the sorting screen plate 8, and the workpiece is discharged from the discharge port 3.

[0048] 7) PLC controller 27 opens drain valve 25 to drain the dirty water in grinding tank 4.

[0049] 8) PLC controller 27 extends the first cylinder 12 through the first solenoid valve 29, and the discharge plate 9 rotates upward; PLC controller 27 extends the second cylinder 21 through the second solenoid valve 30, the silencer 18 opens, the vibrator returns to the initial state, and the next batch of workpieces can be ground.
