Description

Technical Field

[0001] The invention relates to the technical field of cleaning plastic printed matter, and in particular to a multi-stage washer for plastic printed matter and a use method thereof. Background Art

[0002] Plastic printing refers to plastic printed with text and patterns, including plastic film, sheet plastic and other special plastics. Plastics are generally printed with ink, but defective products may appear in the printing process. In order to facilitate the recycling of defective products, the defective plastic printed materials need to be crushed and then cleaned with special cleaning fluid. In the cleaning process, multi-stage cleaning is generally used to clean the ink on the plastic.

[0003] The current multi-stage washer uses multiple cleaning tanks. The crushed plastic is added to the primary cleaning tank for cleaning and then taken out to the second cleaning tank for cleaning. The same method is used for multi-stage cleaning to clean it. However, when cleaning the ink on the plastic printed matter, the ink will float on the surface of the cleaning liquid after it falls off. When the plastic printed matter is taken out, it needs to pass through the surface of the cleaning liquid. At this time, a large amount of ink may be adhered to the plastic printed matter again, and the number of cleaning times required will increase, which may affect the cleaning efficiency and cleaning effect of the plastic printed matter. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a multi-stage washer for plastic printed materials that can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Preferably, the stirring mechanism comprises a rotating shaft which is sealed and rotatably connected in the net barrel, a plurality of stirring rods are fixedly connected to the rotating shaft, a motor is fixedly connected in the sealing column, and an output end of the motor is fixedly connected to the rotating shaft.

[0008] In order to facilitate the discharge of ink on the liquid surface in the cleaning bucket, further, a storage bucket is arranged on one side of the cleaning bucket, an overflow port is arranged between the storage bucket and the cleaning bucket, and a second drain pipe is fixedly connected to one side of the storage bucket.

[0009] Preferably, a return pipe is fixedly connected between the storage barrel and the cleaning barrel, and the return pipe is arranged at the lower side of the cleaning barrel, and a one-way valve and a flow control valve are arranged in the return pipe.

[0010] In order to facilitate the replenishment of cleaning liquid, preferably, a water level detector is fixedly connected to the fixed plate, a supply pump is provided on one side of the cleaning bucket, a supply pipe is fixedly connected to the output end of the supply pump, and the supply pipe is communicated with the cleaning bucket.

[0011] In order to facilitate the rapid rise of the liquid level in the cleaning barrel, further, the axis of the isolation barrel is colinear with the axis of the cleaning barrel, and an annular cavity is provided between the isolation barrel and the cleaning barrel.

[0012] Preferably, a connecting rod is fixedly connected to the upper side of the storage barrel, and a baffle is fixedly connected to the lower end of the connecting rod.

[0013] In order to prevent water overflowing from the overflow port from hitting the liquid surface of the storage barrel, further, a baffle plate is fixedly connected to the baffle plate, and a first gap is arranged between the lower end of the baffle plate and the inner wall of the storage barrel.

[0014] In order to improve the cleaning effect of plastic printed materials, further, the upper end of the rotating shaft is fixedly connected with an inclined plate that fits with the upper side of the net barrel.

[0015] A method for using a multi-stage washer for plastic printed matter mainly comprises the following steps:

[0016] Step 1: Crush the defective plastic printed materials;

[0017] Step 2: Place the crushed plastic into the net bucket, and then thread the threaded net cover to the lower end of the net bucket;

[0018] Step 3: Place the net bucket and sealing column in the isolation bucket;

[0019] Step 4: Stir the plastic in the net barrel through the stirring mechanism so that the ink on the plastic is fully contacted with the cleaning liquid and falls off, and the fallen part of the ink floats on the water surface in the cleaning barrel;

[0020] Step 5: After cleaning, remove the sealing column.

[0021] Compared with the prior art, the present invention provides a multi-stage washer for plastic printed materials, which has the following beneficial effects:

[0022] 1. The multi-stage washer for plastic printed materials controls the motor to rotate the shaft through the controller. At this time, the shaft drives multiple stirring rods to stir the plastic in the net barrel to make it fully contact with the cleaning liquid. At this time, the ink on the plastic is washed and falls off. The density of some water-insoluble ink is lower than the density of water. At this time, part of the ink floats to the water surface of the cleaning barrel. After the cleaning is completed, the sealing column is lifted upward, and the liquid level in the cleaning barrel is always higher than the lower edge of the isolation barrel during the rising process of the sealing column. At this time, the sealing column and the net barrel are not in contact with the liquid surface of the floating impurities, thereby effectively preventing the washed plastic from taking away a large amount of detached ink and affecting the cleaning effect of the plastic printed materials, thereby effectively improving the cleaning effect and cleaning efficiency of the plastic printed materials.

[0023] 2. The multi-stage washer for plastic printed materials, by setting an isolation barrel, a net barrel and a sealing column to work together, prevents the plastic printed materials from contacting the cleaning liquid surface, effectively prevents the cleaned plastic printed materials from taking away floating impurities and ink on the liquid surface again, effectively improves the cleaning effect of the plastic printed materials, and can appropriately reduce the number of multi-stage cleaning of the plastic printed materials.

[0024] 3. In the multi-stage washer for plastic printed materials, after the primary washing barrel washes the plastic printed materials, when the next net barrel containing the plastic printed materials is placed in the isolation barrel, the sealing column squeezes the water in the isolation barrel into the washing barrel, and after the net barrel and the plastic printed materials enter the washing barrel, the liquid level in the washing barrel rises. After the liquid level rises to the overflow port, the water at the liquid surface in the washing barrel flows into the overflow port. After the sealing column completely enters the isolation barrel, the liquid level in the washing barrel rises. At this time, the liquid level in the washing barrel is higher than the liquid level in the storage barrel. At the same time, the one-way valve prevents the liquid in the washing barrel from flowing into the storage barrel. At this time, the ink on the liquid surface of the washing barrel and some floating impurities enter the storage barrel, thereby effectively removing the impurities and ink in the washing barrel, effectively ensuring the cleanliness of the washing liquid in the washing barrel, and thus effectively improving the washing effect of the plastic printed materials.

[0025] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. The present invention effectively prevents the cleaned plastic from taking away a large amount of detached ink and affecting the cleaning effect of the plastic printed matter, thereby effectively improving the cleaning effect and cleaning efficiency of the plastic printed matter.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Example 1: Reference Figure 1-Figure 6 A multi-stage washer for plastic printed materials, comprising: a plurality of washing barrels 1, and also comprising: a fixed plate 102, fixedly arranged on the upper side of the washing barrel 1; an isolation barrel 103, fixedly arranged on the fixed plate 102, and one end of the isolation barrel 103 is arranged in the washing barrel 1; a sealing column 2, sealingly and slidingly connected in the isolation barrel 103; a net barrel 203, arranged on the lower side of the sealing column 2; a hanging buckle 201, fixedly arranged on the top of the sealing column 2; a controller 107, arranged on one side of the washing barrel 1; a stirring mechanism, arranged in the net barrel 203, and the stirring mechanism is used to stir the plastic in the net barrel 203; a threaded net cover 204, threadedly connected to the lower side of the net barrel 203; a first drain pipe 101, arranged on one side of the washing barrel 1.

[0035] The stirring mechanism includes a rotating shaft 205 which is sealed and rotatably connected in the net barrel 203 , a plurality of stirring rods 206 are fixedly connected to the rotating shaft 205 , a motor 202 is fixedly connected in the sealing column 2 , and an output end of the motor 202 is fixedly connected to the rotating shaft 205 .

[0036] The upper end of the rotating shaft 205 is fixedly connected with an inclined plate 207 which is in contact with the upper side of the net barrel 203 .

[0037] When the defective plastic printed materials are washed, the plastic printed materials are broken up by an external breaking mechanism, and then the broken plastic is placed in the net barrel 203 , and the threaded net cover 204 is rotated to seal the lower end of the net barrel 203 .

[0038] An appropriate amount of cleaning liquid is added into the cleaning bucket 1 , wherein the cleaning liquid is a mixture of a cleaning agent and water, and the liquid level in the cleaning bucket 1 is made higher than the lower edge of the isolation bucket 103 .

[0039] The sealing column 2 is hoisted into the primary cleaning barrel 1 by an external crane for cleaning, so that the sealing column 2 is in the isolation barrel 103. During the cleaning process, the controller 107 controls the motor 202 to drive the rotating shaft 205 to rotate. At this time, the rotating shaft 205 drives multiple stirring rods 206 to stir the plastic in the net barrel 203 so that it is fully in contact with the cleaning liquid. At this time, the ink on the plastic is washed off, and the density of some water-insoluble ink is lower than the density of water. At this time, part of the ink floats to the water surface of the cleaning barrel 1. After the cleaning is completed, the sealing column 2 is hoisted upward, and the liquid level in the cleaning barrel 1 is always higher than the lower edge of the isolation barrel 103 during the rising process of the sealing column 2. At this time, the sealing column 2 and the net barrel 203 are not in contact with the liquid surface of the floating impurities, thereby effectively preventing the cleaned plastic from taking away a large amount of detached ink and affecting the cleaning effect of the plastic printed matter, thereby effectively improving the cleaning effect and cleaning efficiency of the plastic printed matter.

[0040] After the cleaning is completed in the primary cleaning barrel 1, the sealing column 2 in the primary cleaning barrel 1 is hoisted to the isolation barrel 103 of the next-level cleaning barrel 1 for secondary cleaning.

[0041] By setting up the isolation barrel 103, the net barrel 203 and the sealing column 2 to work together, the plastic printed matter is prevented from contacting the cleaning liquid surface, effectively preventing the cleaned plastic printed matter from taking away floating impurities and ink on the liquid surface again, effectively improving the cleaning effect of the plastic printed matter, and appropriately reducing the number of multi-stage cleaning of the plastic printed matter.

[0042] The rotating shaft 205 and the stirring rod 206 stir the plastic printed material in the net barrel 203, which can effectively reduce the turbulence of the cleaning liquid between the net barrel 203 and the cleaning barrel 1, thereby facilitating the floating of grease in the cleaning liquid between the cleaning barrel 1 and the net barrel 203, thereby effectively reducing the amount of ink mixed in the cleaning liquid.

[0043] The tilting plate 207 rotates in the net barrel 203 to press the floating plastic downward, and the stirring rod 206 rotates along the rotating shaft 205 to fully stir it, so that the plastics in the net barrel 203 rub against each other, thereby effectively improving the cleaning effect of plastic printed materials.

[0044] Example 2: Reference Figure 1-Figure 6 A multi-stage washer for plastic printed materials is basically the same as Example 1, further, a storage barrel 3 is set on one side of the cleaning barrel 1, an overflow port 304 is set between the storage barrel 3 and the cleaning barrel 1, and a second drain pipe 305 is fixedly connected to one side of the storage barrel 3.

[0045] A return pipe 301 is fixedly connected between the storage barrel 3 and the cleaning barrel 1 , and the return pipe 301 is arranged at the lower side of the cleaning barrel 1 . A one-way valve 302 and a flow control valve 303 are arranged in the return pipe 301 .

[0046] The axis of the isolation barrel 103 is colinear with the axis of the cleaning barrel 1 , and an annular cavity 105 is provided between the isolation barrel 103 and the cleaning barrel 1 .

[0047] After the primary cleaning barrel 1 cleans the plastic printed material, when the next net barrel 203 containing the plastic printed material is placed in the isolation barrel 103, the sealing column 2 squeezes the water in the isolation barrel 103 into the cleaning barrel 1, and after the net barrel 203 and the plastic printed material enter the cleaning barrel 1, the liquid level in the cleaning barrel 1 rises. After the liquid level rises to the overflow port 304, the water at the liquid surface in the cleaning barrel 1 flows into the overflow port 304. After the sealing column 2 completely enters the isolation barrel 103, the liquid level in the cleaning barrel 1 rises. At this time, the liquid level in the cleaning barrel 1 is higher than the liquid level in the storage barrel 3. At the same time, the one-way valve 302 prevents the liquid in the cleaning barrel 1 from flowing into the storage barrel 3. At this time, the ink on the liquid surface of the cleaning barrel 1 and some floating impurities enter the storage barrel 3, thereby effectively removing the impurities and ink in the cleaning barrel 1, effectively ensuring the cleanliness of the cleaning liquid in the cleaning barrel 1, and thus effectively improving the cleaning effect of the plastic printed material.

[0048] After cleaning, the sealing column 2 is lifted. At this time, the liquid level in the cleaning barrel 1 drops, and the cleaning liquid in the storage barrel 3 slowly flows back to the cleaning barrel 1 through the reflux pipe 301, so that the liquid levels in the storage barrel 3 and the cleaning barrel 1 are the same. At this time, the floating objects and ink in the storage barrel 3 float on the upper side, thereby preventing the floating ink and floating impurities from flowing back into the cleaning barrel 1 again.

[0049] After a period of use, the controller 107 controls the electromagnetic valve in the second drain pipe 305 to open, so as to discharge the floating impurities and ink in the storage barrel 3 , and add a proper amount of cleaning liquid into the storage barrel 3 .

[0050] The flow rate of the liquid in the storage barrel 3 flowing into the cleaning barrel 1 is controlled by setting a flow control valve 303, so that it flows slowly. After the net barrel 203 is pulled out, the plastic inside it takes away the water in the cleaning barrel 1, causing the water level in the cleaning barrel 1 to drop instantly, and the water in the storage barrel 3 flows back through the reflux pipe 301, and then the water in the net barrel 203 slowly flows out into the cleaning barrel 1, causing the water level in the cleaning barrel 1 to rise. At this time, the water level in the cleaning barrel 1 is higher than the water level in the storage barrel 3, thereby affecting the storage amount of floating ink and impurities in the storage barrel 3. The flow control valve 303 is set for slow reflux, so that the storage barrel 3 can store floating ink and impurities.

[0051] Example 3: Reference Figure 1-Figure 6 , a multi-stage washer for plastic printed materials, which is basically the same as Example 1, and further, a connecting rod 4 is fixedly connected to the upper side of the storage barrel 3, and a baffle 401 is fixedly connected to the lower end of the connecting rod 4.

[0052] A baffle plate 402 is fixedly connected to the baffle plate 401 , and a first gap is provided between the lower end of the baffle plate 402 and the inner wall of the storage barrel 3 .

[0053] When water overflows from the overflow port 304, the overflowing water flows onto the baffle plate 401, and then is guided by the inclined baffle plate 402 to flow onto the inner wall of the storage barrel 3, and then flows downward along the inner wall, effectively preventing the water flowing out of the overflow port 304 from directly colliding with the water in the storage barrel 3, thereby effectively preventing the floating grease and impurities from being mixed with the water in the storage barrel 3 again, and further effectively preventing the water in the storage barrel 3 from returning and bringing the floating grease and impurities into the cleaning barrel 1 again, affecting the cleaning effect on the plastic printed matter.

[0054] Example 4: Reference Figure 1-Figure 6 , a multi-stage washer for plastic printed materials, which is basically the same as Example 1, and further, a water level detector 104 is fixedly connected to the fixed plate 102, a supply pump 106 is provided on one side of the cleaning barrel 1, and a supply pipe 108 is fixedly connected to the output end of the supply pump 106, and the supply pipe 108 is connected to the cleaning barrel 1.

[0055] The supply pipe 108 is communicated with the storage barrel 3 .

[0056] After completing a cleaning process, the sealing column 2 and the net bucket 203 are taken out, the liquid level in the cleaning bucket 1 is detected by the water level detector 104, and then the volume of cleaning liquid to be added is calculated by the controller 107. The controller 107 controls the supply pump 106 to supply cleaning liquid to the storage bucket 3, so that the liquid level in the storage bucket 3 rises to a certain height and then slowly decreases, thereby ensuring that the liquid level in the storage bucket 3 is consistent with the liquid level in the cleaning bucket 1.

[0057] If cleaning liquid is directly added into the cleaning barrel 1, after the sealing column 2 and the mesh barrel 203 are placed, the water flow overflowing from the overflow port 304 becomes larger. At this time, the baffle plate 402 may not be able to keep up with the flow diversion speed, which may affect the discharge effect of ink and impurities on the liquid surface of the cleaning barrel 1.

[0058] Embodiment 5: A method for using a multi-stage washer for plastic printing, mainly comprising the following steps:

[0059] Step 1: Crush the defective plastic printed materials;

[0060] Step 2: Place the crushed plastic into the net bucket 203, and then thread the threaded net cover 204 to the lower end of the net bucket 203;

[0061] Step 3: Place the net bucket 203 and the sealing column 2 in the isolation bucket 103;

[0062] Step 4: Stir the plastic in the net barrel 203 by means of a stirring mechanism, so that the ink on the plastic is fully in contact with the cleaning liquid and falls off, and the fallen part of the ink floats on the water surface in the cleaning barrel 1;

[0063] Step 5: After cleaning, take out the sealing column 2.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
