Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a cleaning device used in the production of plastic parts. Background Technology

[0002] Plastic parts are components or parts made of plastic materials and are widely used in electronics, automotive, medical, aerospace, construction, and other fields. In the production process of plastic parts, surface treatment cleaning equipment is indispensable. This type of equipment can remove oil, dust, and other impurities from the surface of plastic parts, improving the appearance quality of the product.

[0003] A cleaning device for surface treatment of plastic parts, disclosed in publication number CN217990252U, includes a mounting frame and a mounting plate. The mounting frame has an "n"-shaped cross-section in its main view. A sliding opening is formed in the top wall of the mounting frame, and a mounting block is slidably mounted within the inner cavity of the sliding opening in a left-right direction. A vertically oriented electric lifting rod is mounted on the bottom wall of the mounting block. A small ultrasonic cleaner and a drying chamber are located below the electric lifting rod. The drying chamber is a hollow rectangular body with an open top wall, and drying fans are symmetrically arranged on the front and rear side walls of the inner cavity of the drying chamber. This utility model can perform ultrasonic cleaning and drying on multiple plastic mobile phone casings simultaneously.

[0004] The inventors have discovered at least the following problems in the prior art:

[0005] First, the above-mentioned equipment requires the plastic phone case to be installed between multiple sliding plates before cleaning. In addition, the drying air cannot reach the contact area between the plastic phone case and the sliding plates during drying. Therefore, not only will the clamped parts not be cleaned, limiting the number of cases that can be cleaned each time, but it is also very easy to dry unevenly during drying.

[0006] Secondly, the process of drying the plastic phone casing after cleaning requires the cooperation of a motor and a lifting rod to transfer the cleaned plastic phone casing into the drying chamber. Therefore, the operation is not only cumbersome, but also increases the cost of use.

[0007] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0008] In order to overcome the shortcomings of the existing technology, this utility model proposes a cleaning device for surface treatment of plastic parts.

[0009] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0010] A cleaning device for surface treatment of plastic parts includes a cleaning tank and a drying chamber. A connecting member is provided between the cleaning tank and the drying chamber. A flipping mechanism is provided above the connecting member. A drive motor is installed on one side of the connecting member. An arc-shaped guide rail is fixedly connected above the cleaning tank and the drying chamber. A bearing mechanism is provided around the flipping mechanism. Connecting mechanisms are provided at both ends of the bearing mechanism. A pneumatic mechanism is provided inside the drying chamber. The flipping mechanism includes a flipping shaft and a receiving frame fixedly connected to one side of the flipping shaft. Vertical guide rail two and vertical guide rail one are fixedly connected to the upper and lower parts of the receiving frame, respectively. The bearing mechanism includes a bearing cylinder and fan blades fixedly connected to both ends of the bearing cylinder. A guide wheel is rotatably connected to one end of the bearing cylinder. The pneumatic mechanism includes an air jet pipe and a curved pipe, which cooperate with the bearing cylinder. The connecting mechanism includes a sliding block one and a sliding block two, which are located at both ends of the bearing cylinder, and one side of each sliding block one and sliding block two is slidably connected inside the vertical guide rail two and vertical guide rail one.

[0011] Preferably, the two ends of the bearing cylinder are respectively fixedly connected to a rotating shaft one and a rotating shaft two, the guide wheel is located on one side of the rotating shaft one, the rotating shaft one is rotatably connected to the inside of the sliding block one, and the rotating shaft two is rotatably connected to the inside of the sliding block two.

[0012] Preferably, a spring is provided inside the sliding block two, and the spring is located on one side of the rotating shaft two.

[0013] Preferably, one side of the sliding block has a cut surface, and the guide wheel fits into the cut surface.

[0014] Preferably, the output end of the drive motor is connected to a drive chain, which surrounds one end of the rotating shaft and is movably connected inside the connector.

[0015] Preferably, an induced draft fan is installed on the outside of the drying oven, and the output end of the induced draft fan is connected to an air jet pipe. A flared mouth is provided at one end of the air jet pipe and the curved pipe that are close to each other.

[0016] Preferably, a second door panel is movably connected to the periphery of the bearing cylinder, a first door panel is provided on one side of the drying box, and the bottom surface inside the drying box is an inclined bottom surface.

[0017] The beneficial effects of this utility model are:

[0018] The technical solution of this utility model is as follows: By cooperating with the set flipping mechanism, bearing mechanism, pneumatic mechanism and connecting mechanism, when cleaning plastic mobile phone cases, they are first placed inside the bearing cylinder, and then the cleaning tank is opened for cleaning. Afterwards, the entire bearing mechanism and connecting mechanism can be flipped into the drying box for drying. After flipping, the bearing mechanism can be driven by the pneumatic mechanism to generate self-rotation. This not only allows for the cleaning and drying of a larger number of plastic mobile phone cases, but also reduces the number of operation steps in the cleaning and drying process, thereby reducing the cost of use.

[0019] The technical solution of this utility model is as follows: through the cooperation of the flipping mechanism, the bearing mechanism, the pneumatic mechanism and the connecting mechanism, when the bearing mechanism is driven to rotate by the airflow blown from the jet pipe and the curved pipe, the connecting mechanism can also make the bearing mechanism slide back and forth. The airflow can also accelerate the flow of air inside the drying chamber, thereby ensuring that the plastic parts are subjected to uniform heat and airflow throughout the drying process, and thus the drying is more uniform.

[0032] The following will be combined with the appendix Figure 1 To be continued Figure 5 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0033] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0034] Reference Figures 1-6 As shown, this utility model provides a cleaning device for surface treatment of plastic parts, including a cleaning tank 1 and a drying box 2. A connecting part 3 is provided between the cleaning tank 1 and the drying box 2. A flipping mechanism 6 is provided above the connecting part 3. A drive motor 4 is installed on one side of the connecting part 3. An arc-shaped guide rail 5 is fixedly connected above the cleaning tank 1 and the drying box 2. A bearing mechanism 7 is provided around the flipping mechanism 6. A connecting mechanism 9 is provided at both ends of the bearing mechanism 7. A pneumatic mechanism 8 is provided inside the drying box 2.

[0035] The flipping mechanism 6 includes a flipping shaft 61 and a receiving frame 62 fixedly connected to one side of the flipping shaft 61. Vertical guide rail 65 and vertical guide rail 64 are fixedly connected to the upper and lower parts of the receiving frame 62, respectively.

[0036] The bearing mechanism 7 includes a bearing cylinder 71 and wind turbine blades 72 fixedly connected to both ends of the bearing cylinder 71. A guide wheel 75 is rotatably connected to one end of the bearing cylinder 71.

[0037] The pneumatic mechanism 8 includes a jet pipe 81 and a curved pipe 82, which cooperate with the bearing cylinder 71.

[0038] The connecting mechanism 9 includes a sliding block 1 91 and a sliding block 2 92. The sliding block 1 91 and the sliding block 2 92 are located at the two ends of the bearing cylinder 71, and one side of the sliding block 1 91 and the sliding block 2 92 are slidably connected to the inside of the vertical guide rail 2 65 and the vertical guide rail 1 64.

[0039] The cleaning tank 1 is an existing ultrasonic cleaning device for cleaning plastic parts, containing cleaning fluid and equipped with a controller on the outside; the drying box 2 has two pairs of drying fans installed on its inner side wall for drying the plastic parts.

[0040] Auxiliary rollers 63 are rotatably connected to both sides of the receiving frame 62. The auxiliary rollers 63 fit into the inner wall of the arc-shaped guide rail 5, thereby maintaining stability during the flipping of the entire flipping mechanism 6.

[0041] The receiving frame 62, vertical guide rail 2 65 and vertical guide rail 1 64 all have guide grooves. The inside of the guide groove is equipped with a buffer pad to protect the free fall of the bearing mechanism 7 after flipping. The inner wall of the guide groove fits the sliding block 1 91 and sliding block 2 92. The height of vertical guide rail 2 65 is higher than that of vertical guide rail 1 64. Therefore, when the flipping mechanism 6 flips and the bearing mechanism 7 enters the interior of the drying box 2, the chamfer of the fan blade 72 can be located exactly between the jet pipe 81 and the curved pipe 82.

[0042] In a further embodiment, the two ends of the bearing cylinder 71 are respectively fixedly connected to a rotating shaft 73 and a rotating shaft 74, the guide wheel 75 is located on one side of the rotating shaft 73, the rotating shaft 73 is rotatably connected to the inside of the sliding block 91, and the rotating shaft 74 is rotatably connected to the inside of the sliding block 92.

[0043] In this embodiment, both the first rotating shaft 73 and the second rotating shaft 74 are provided with limit disks, so that they can rotate inside the first sliding block 91 and the second sliding block 92, and can also slide. The first sliding block 91 and the second sliding block 92 are both composed of a cylinder and a slider. The slider part is slidably connected inside the second vertical guide rail 65 and the first vertical guide rail 64, while the cylinder is connected to the first rotating shaft 73 and the second rotating shaft 74.

[0044] In a further embodiment, a spring 94 is provided inside the sliding block 92, and the spring 94 is located on one side of the rotating shaft 74.

[0045] In this embodiment, the spring 94 is mainly used to continuously push the rotating shaft 74 and the entire bearing cylinder 71 close to the sliding block 91. During the rotation of the bearing cylinder 71, the cooperation between the guide wheel 75 and the cut surface 93 will cause the entire bearing mechanism 7 to slide back and forth.

[0046] In a further embodiment, a cut surface 93 is provided on one side of the sliding block 91, and the guide wheel 75 fits into the cut surface 93.

[0047] In this embodiment, the cut surface 93 is formed in its cylindrical part, and the cross section of the cut surface 93 is arc-shaped. Therefore, when the guide wheel 75 is in contact with its surface and the bearing cylinder 71 rotates, the bearing cylinder 71 will be passively allowed to slide back and forth. The bearing cylinder 71 has a protruding ear plate at the guide wheel 75, and the guide wheel 75 is rotatably connected to the ear plate.

[0048] In a further embodiment, the output end of the drive motor 4 is connected to a drive chain 41, which surrounds one end of the rotating shaft 61 and is movably connected inside the connector 3.

[0049] In this embodiment, the flip shaft 61 is rotatably connected above the connector 3 via a rotating shaft, and a sprocket is provided on the periphery of the rotating shaft at one end, so that it can cooperate with the drive chain 41.

[0050] In a further embodiment, an exhaust fan 83 is installed on the outside of the drying chamber 2. The output end of the exhaust fan 83 is connected to an air jet pipe 81. A flared mouth 84 is provided at one end of the air jet pipe 81 and the curved pipe 82 that are close to each other.

[0051] In this embodiment, the curved pipe 82 is arc-shaped, with one end aligned with the jet pipe 81 and the other end facing the chamfer of the wind turbine blade 72. It is mainly used to drive the wind turbine blade 72 and the entire support cylinder 71 to rotate. The flared mouth 84 is used to expand the range of the air vent, so that the airflow ejected from the jet pipe 81 can better enter the curved pipe 82, and at the same time, it can also adapt to the support cylinder 71 that is sliding back and forth.

[0052] In a further embodiment, a second door panel 76 is movably connected to the periphery of the bearing cylinder 71, a first door panel 21 is provided on one side of the drying box 2, and the bottom surface inside the drying box 2 is an inclined bottom surface 22.

[0053] In this embodiment, door panel 76 is connected to the bearing cylinder 71 via a hinge, and is used to open and place in and take out plastic parts. When door panel 76 is opened inside the drying chamber 2, the plastic parts can fall into the drying chamber 2 and be guided by the inclined bottom surface 22 to be concentrated near door panel 21. At this time, door panel 21 can be opened to collect the plastic parts, which makes unloading more convenient. In addition, the inclined bottom surface 22 needs to be cleaned after each unloading to prevent contamination of the cleaned plastic parts during the unloading process.

[0054] The working principle of this utility model is as follows:

[0055] After a certain number of plastic parts are put into the inside of the carrier cylinder 71, the door panel 76 is closed. Then the cleaning tank 1 is turned on to clean the plastic parts immersed in the carrier cylinder 71. After cleaning, the drive motor 4 can be operated by the controller outside the cleaning tank 1. This drives the entire flipping mechanism 6, the carrier mechanism 7 and the connecting mechanism 9 to rotate around the flipping shaft 61 via the drive chain 41. This causes the carrier mechanism 7 and the connecting mechanism 9 to flip into the inside of the drying chamber 2. Then the drying fan inside the drying chamber 2 is turned on for drying.

[0056] During the drying process, the controller can operate the blower 83, which will cause the jet pipe 81 to spray out high-pressure airflow. The airflow will drive the fan blade 72, and after passing through the fan blade 72, it will be guided by the curved pipe 82 and blow back to the fan blade 72, thereby causing the bearing cylinder 71 to rotate. The sprayed airflow can also accelerate the flow of air inside the drying chamber 2, thereby accelerating the drying process of the plastic parts.

[0057] During the rotation of the bearing cylinder 71, the guide wheel 75, which is fixedly connected to one end of the bearing cylinder 71, will roll along the surface of the cut surface 93. In conjunction with the spring 94, which is rotatably connected to the other end of the bearing cylinder 71 in the sliding block 92, the entire bearing cylinder 71 will sway left and right during the rotation, thus making the drying process more uniform.

[0058] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
