Description

Automatic workpiece cleaning machine

technical field

The invention relates to a cleaning device, in particular to a fully automatic workpiece cleaning machine for cleaning workpieces of different sizes.

Background technique

In the mechanical industry, the cleanliness of the workpiece surface affects the quality of the workpiece, so cleaning the workpiece surface is a very important link. At present, different cleaning fluids are used to clean the workpiece. After cleaning through multiple processes, the workpiece is generally placed in the drum. There are screen holes on the outer wall of the drum, and the drum is placed in the solution pool for rolling cleaning. However, the amount of cleaning liquid required for such cleaning is very large, resulting in high cost; cleaning is troublesome. After cleaning a process, it is necessary to take out all the workpieces and put them into the drum in the next process, which is very troublesome and takes a lot of time. It leads to low work efficiency; it is difficult to clean thoroughly. The cleaning liquid enters from the screen hole on the outer wall of the drum and stays in the drum to clean the workpiece. Get it all out.

Contents of the invention

The present invention aims to solve the above-mentioned shortcomings of the prior art, and provides a fully automatic workpiece cleaning machine, which has a compact and simple structure, can recycle various cleaning liquids, and cleans them thoroughly, requiring less cleaning liquid.

The technical solution adopted by the present invention to solve its technical problems: this fully automatic workpiece cleaning machine includes a casing and a drum, the two ends of the drum are axially connected to the casing, the casing is provided with a motor to drive the rotation of the drum, and the drum is located on On the upper part of the casing, there is a cover plate on the drum, and one end of the cover plate is hinged on the drum, and the wall of the drum is provided with sieve holes distributed at intervals, and a liquid spray pipe with a spray port is arranged inside the drum; The sieve plate is installed obliquely, the outer end of the sieve plate is connected to the discharge port outside the casing; there is a cavity under the sieve plate, and the bottom of the cavity is provided with a cleaning liquid outlet and a clean water outlet, and a cleaning liquid outlet and a clean water outlet There are sealing plugs for opening and closing the outlet at the top; the cleaning liquid outlet and the clean water outlet are respectively connected to the cleaning liquid storage tank and the clean water storage tank through the liquid outlet pipes, and the cleaning liquid storage tank and the clean water storage tank are connected to each other. Water pumps are respectively provided, and the water pumps are connected with the inlets of the spray pipes through water pipes.

The bottom of the cavity is provided with a cleaning liquid outlet and a clean water outlet, and the bottom of the casing is correspondingly provided with a cleaning liquid storage tank and a clean water storage tank, and the cleaning liquid storage tank and the clean water storage tank store the required cleaning liquid respectively. and clean water, the cleaning liquid or clean water is pumped into the spray pipe through the water pump to rinse the workpiece. If washing the workpiece with cleaning liquid, open the sealing plug on the cleaning liquid outlet and close the sealing plug on the clean water outlet, so that the cleaning liquid after rinsing the workpiece flows back into the cleaning liquid storage tank; use the same principle to wash the workpiece with clean water. In this way, it is not necessary to take the workpiece out of the drum to complete the multi-channel flushing process for the workpiece, which is simple and convenient to operate and high in work efficiency.

The structure of the machine is compact and the overall structure is simple. The roller is set on the top of the casing, which is convenient for putting the workpiece into the roller and observing the condition of the roller; the nozzle is used to clean the workpiece in the roller, and the cleaning liquid in the nozzle is applied by the water pump. Cleaning by means of spraying is cleaner, and the workpiece in the drum is cleaned in a large area, with high cleaning efficiency. The cleaning liquid is injected from the spray pipe and flows out from the screen holes on the outer wall of the drum. The cleaning liquid keeps flowing in the direction of discharge. , so that the waste residue on the workpiece is discharged together with the cleaning liquid, and the cleaning is more thorough; the cleaning liquid that flows out after cleaning falls in the cavity, and flows from the corresponding liquid outlet to the liquid storage tank, and the waste residue is left in the filter through the filter device. In the liquid storage tank, the clean cleaning liquid is re-drawn to the injection pipe for recycling through the water pump, which saves the amount of cleaning liquid.

A control device is also installed in the casing, the control device controls the rotation of the drum and the cylinder on the liquid outlet, the control device controls the rotation speed of the drum, and keeps a slow speed during normal cleaning, and speeds up the rotation speed of the drum after cleaning to achieve The effect of drying; and the cylinder pushes and pulls each sealing plug to control the on-off of the liquid outlet.

In order to be further improved, the bottom of the cavity is provided with an anti-rust liquid outlet, and the anti-rust liquid outlet is connected with a liquid outlet pipe. The outlet of the liquid pipe is correspondingly provided with an anti-rust liquid storage tank. A water pump is arranged inside, a water pipe is connected to the water pump, a check valve is arranged on the water pipe, and the outlet of the water pipe is connected to the inlet of the liquid spray pipe. Firstly, the workpiece is cleaned with cleaning solution, and then dried, then rinsed with clean water, brushed again, and sprayed with anti-rust liquid on the surface of the workpiece, which can prevent the workpiece from rusting and improve the service life of the workpiece.

The drum is round, and the round drum is suitable for larger workpieces. When the workpiece rolls in the drum, due to the larger volume, the collision force between the workpieces and between the workpiece and the inner wall of the drum is relatively large. The damage of the workpiece due to collision can be reduced, thereby improving the quality of the workpiece.

The rollers are polygonal. This structure is suitable for small workpieces. When the workpieces are rolling in the drum, due to the small size, the collision force between the workpieces and between the workpieces and the inner wall of the drum is small, and the workpieces cannot be dispersed, resulting in insufficient cleaning of the workpieces by the cleaning solution. thorough.

The motor is connected to one end of the drum, and the inlet of the liquid spray pipe is located at the other end of the drum, and the inlet of the liquid spray pipe stretches out of the drum and is connected with various water pipes. The structure of this design is reasonable, more compact, and the overall volume of the machine is reduced.

A cover is arranged above the drum. The cover shell plays a protective role, and also prevents the liquid in the drum from splashing outwards.

Wherein the sealing plug is fixed on the cylinder, the cylinder is fixed on the mounting plate, and the mounting plate is fixed in the casing.

The beneficial effects of the present invention are: the structural design of the present invention is reasonable, although the structure is comparatively simple, but the realized function is powerful, can realize the cleaning of various cleaning fluids to workpiece, adopt the mode of flushing, make the waste residue on the workpiece with cleaning fluid The flow is completely discharged from the drum, the cleaning effect is good, the cleaning liquid can be recycled, which saves the amount of cleaning liquid, and it is convenient to clean. Put the workpiece into the drum to complete multiple cleaning processes. The drum also has a drying function. Simple, suitable for cleaning workpieces of different sizes, and conducive to wide use.
