Description

Technical Field

[0001] This utility model relates to the field of packaging material processing technology, specifically to a raw material cleaning device for packaging materials. Background Technology

[0002] Packaging materials refer to the materials used in manufacturing packaging containers, packaging decoration, packaging printing, packaging transportation, etc., to meet the packaging requirements of products. They include major packaging materials such as metals, plastics, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, chemical fibers, and composite materials, as well as auxiliary materials such as strapping, decoration, and printing materials. For example, in the production and processing of packaging bags made from plastic, the raw plastic material needs to be cleaned using a cleaning device. The traditional cleaning method involves placing plastic granules in a material frame and then rinsing the plastic with high-pressure water. However, when plastic granules with stubborn dust accumulate, rinsing alone cannot completely clean them, resulting in poor cleaning effects. Therefore, we propose a raw material cleaning device for packaging materials to solve the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a raw material cleaning device for packaging materials, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A raw material cleaning device for packaging materials includes a water tank. Two cleaning chambers are fixed to the top of the water tank via four supports. A rotating shaft is rotatably connected to each side wall of the two cleaning chambers via bearings. A rubbing plate adapted to the cleaning chamber is fixed to one end of each rotating shaft. Raised strips are fixed to one side wall of each rubbing plate in a circular array. A filter screen is fixed inside an opening in the outer wall of each cleaning chamber. A guide shell is fixed to the outer wall of each cleaning chamber outside the filter screen. A baffle is fixed inside a slot on the surface of the guide shell. A discharge pipe is fixed to the outer wall of each cleaning chamber. An electromagnetic butterfly valve is installed on each discharge pipe. Cleaning pipes are fixed to the outer walls of both cleaning chambers. A water pump is fixed to the top of the water tank. The inlet pipe of the water pump passes through the water tank and extends into it. The outlet pipe of the water pump is fixed to the cleaning pipes. A filter assembly is installed at the inlet at the top of the water tank.

[0006] Furthermore, the filter assembly includes a limiting seat fixed at the water inlet of the water tank, a filter bucket placed on the top of the limiting seat, a frame plate fixed inside the filter bucket, and an activated carbon honeycomb plate layer, a cotton cloth filter layer and a filter screen layer placed sequentially from bottom to top on the top of the frame plate.

[0007] Furthermore, each of the four rotating shafts has a sprocket fixed to its surface, and the corresponding two sprockets are connected by a chain drive.

[0008] Furthermore, each of the cleaning chambers has a mounting block fixed to its front side, and each mounting block has a vibration motor fixed inside its mounting groove.

[0009] Furthermore, each slot on the surface of the flow guide shell is fixed with a square sealing ring, and the baffle is tightly fitted with the corresponding square sealing ring.

[0010] Furthermore, each of the cleaning chambers is equipped with a feeding pipe at its top, and the feeding pipe inlet is funnel-shaped.

[0011] Compared with the prior art, the present invention provides a raw material cleaning device for packaging materials, which has the following beneficial effects:

[0012] This utility model, by setting up a water tank, a cleaning chamber, a rotating shaft, a rubbing plate, raised strips, a water filter screen, a flow guide shell, a baffle, a discharge pipe, a cleaning pipe, a water pump, and a filter assembly, allows the plastic raw material particles from the packaging bag to be sent into the cleaning chamber. Inside the cleaning chamber, the plastic raw material particles are repeatedly cleaned and rubbed by two counter-rotating rubbing plates, so as to more thoroughly remove the impurities adhering to their surfaces. The water used for cleaning is filtered by the filter assembly and can then flow back into the water tank for recycling. Furthermore, it makes it easier to remove and replace the filter assembly later. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of this utility model discloses a raw material cleaning device for packaging materials, including a water tank 1. Two cleaning chambers 2 are fixed to the top of the water tank 1 via four supports. Each cleaning chamber 2 has a feeding pipe 18 fixed to its top. The inlet of each feeding pipe 18 is funnel-shaped, facilitating the feeding of plastic raw material granules into the cleaning chamber 2 for cleaning. Two rotating shafts 3 are rotatably connected to the side walls of each cleaning chamber 2 via bearings. Each of the four rotating shafts 3 has a sprocket 13 fixed to its surface. Corresponding sprockets 13 are connected by a chain 14, allowing the four rotating shafts 3 to rotate simultaneously under the action of two motors, thereby saving production costs. A kneading plate 4, adapted to the cleaning chamber 2, is fixed to one end of each rotating shaft 3 for kneading. One side wall of plate 4 is fixed with protruding strips 5 in a circular array. A filter screen 6 is fixed inside the opening on the outer wall of the cleaning chamber 2. A guide shell 7 is fixed to the outer wall of the cleaning chamber 2 on the outside of each filter screen 6. A baffle 8 is fixed inside the slot on the surface of the guide shell 7. A square sealing ring 17 is fixed inside the slot on the surface of the guide shell 7. The baffle 8 fits tightly with the corresponding square sealing ring 17, thus preventing cleaning water from overflowing from the contact point between the guide shell and the baffle 8 when the cleaning chamber 2 drains. A discharge pipe 9 is fixedly connected to the outer wall of each cleaning chamber 2. An electromagnetic butterfly valve 19 is installed on each discharge pipe 9. Cleaning pipes 10 are fixed to the outer walls of both cleaning chambers 2. A water pump 11 is fixed to the top of the water tank 1. The water inlet of the water pump 11... A pipe runs through the water tank 1 and extends into it. The outlet pipe of the water pump 11 is connected and fixed to the cleaning pipe 10. A filter assembly 12 is installed at the water inlet at the top of the water tank 1. When using this packaging material cleaning device, the plastic raw material particles of the packaging bag can be sent into the cleaning chamber 2. At this time, the plastic raw material particles sent into it will be located between the two rubbing plates 4. Then, the water pump 11 can be started. After the water pump 11 starts, it can pump the cleaning water in the water tank 1 into the cleaning pipe 10. Then, through the cleaning pipe 10, it can be divided into the two cleaning chambers 2. Starting the two motors to rotate in opposite directions can drive the rubbing plates 4 on both sides to rotate in opposite directions. During the rotation of the rubbing plates 4, with the cooperation of the convex strips 5, the plastic raw material particles can be repeatedly rubbed. To ensure a thorough cleaning, the baffle 8 is opened after cleaning. The cleaning water then flows down through the filter screen 6 and the guide shell 7, and finally returns to the water tank 1 after being filtered by the filter assembly 12. If the plastic raw material granules need to be cleaned again after the first cleaning, simply repeat the above steps. Alternatively, a second cleaning method can be selected. After filling the cleaning chamber 2 with water to a certain height, the baffle 8 can be opened to a certain distance, and more cleaning water can be added to the cleaning chamber 2. This allows for the circulation of cleaning water to clean the plastic raw material granules. Finally, after the plastic raw material granules have been cleaned, the solenoid butterfly valve 19 on the discharge pipe 9 is opened, and the cleaned plastic raw material granules are discharged from the cleaning chamber 2.Curved viewing windows are installed on the outer wall of the washing chamber 2, making it convenient for staff to check the amount of plastic being added.

[0020] like Figure 2 and Figure 4 As shown, in some embodiments, the filter assembly 12 includes a limiting seat 1201 fixed at the water inlet of the water tank 1. A filter bucket 1202 is placed on the top of the limiting seat 1201. A frame plate 1203 is fixed inside the filter bucket 1202. An activated carbon honeycomb plate layer 1204, a cotton cloth filter layer 1205, and a filter screen layer 1206 are placed sequentially from bottom to top on the top of the frame plate 1203. In use, the cleaning water after use will fall into the interior of the filter bucket 1202 through the guide bucket 7. After being filtered by the activated carbon honeycomb plate layer 1204, the cotton cloth filter layer 1205, and the filter screen layer 1206, it will flow back into the interior of the water tank 1. Since the filter bucket 1202 is placed on the limiting seat 1201, and the activated carbon honeycomb plate layer 1204, the cotton cloth filter layer 1205, and the filter screen layer 1206 are all placed inside the filter bucket 1202, it can be easily removed for cleaning or replacement later.

[0021] like Figure 1 As shown, in some embodiments, mounting blocks 15 are fixed to the front of the cleaning chamber 2, and vibration motors 16 are fixed inside the mounting slots of the mounting blocks 15. During the unloading process after cleaning, starting the vibration motors 16 can cause the cleaning chamber 2 to vibrate, so as to speed up the unloading speed inside and discharge the raw material particles more thoroughly.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
