Description

Technical Field

[0001] This invention relates to the field of battery recycling technology, and in particular to a rotary polishing device for the outer surface of a fuel filter housing. Background Technology

[0002] A filter is an accessory that uses filter paper to filter impurities or gases. According to different filtration functions, it can be divided into oil filters, fuel filters (gasoline filters, diesel filters, oil-water separators and hydraulic filters), air filters and cabin air filters, etc.

[0003] The filter housing is a container for the filter, and it is cylindrical. After processing and forming, the filter housing needs to be polished to make it smoother. Chinese Patent (Announcement No.: CN112108950A) discloses an end face polishing device for filter processing. The wheel set is installed on the outer wall of the column through bearings. One wheel on the left side of the column is installed on the worktable through bearings. A second pulley is installed at the bottom position of the left side of the column. The first pulley and the second pulley are connected by belt drive. An installation plate is fixedly installed at the top position of the inner cavity of the box. While ensuring working stability, the polishing efficiency is improved.

[0004] However, the above-mentioned patent only ensures the stability of the working process and does not take into account the large amount of debris generated during grinding that splashes in all directions. If the debris enters other components and causes accidents, in addition, during repeated grinding, a certain amount of debris will adhere to the surface. If it is not cleaned in time, it will further affect the grinding quality and greatly reduce the overall smoothness of the filter housing. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by providing a rotary polishing device for the outer surface of a fuel filter housing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rotary polishing device for the outer surface of a fuel filter housing, comprising an operation box, wherein a guide rail is provided inside the operation box near the top, and a movable block is movably connected to the outer surface of the guide rail, and an electric telescopic rod is fixedly connected to the lower outer surface of the movable block.

[0007] One end of the electric telescopic rod is fixedly connected to the moving block, and the other end is fixedly connected to a U-shaped frame. A grinding roller is rotatably connected inside the U-shaped frame, and a motor is set at the position corresponding to the grinding roller on one side of the outer surface of the U-shaped frame. The output end of the motor passes through the inside of the U-shaped frame and is fixedly connected to the grinding roller.

[0008] Electric push rods are provided on both sides of the inner surface of the control box. One end of the electric push rod is fixedly connected to a connecting block. A motor is provided on one outer surface of the connecting block. A connecting frame is fixedly connected to the output end of the motor. A collection frame for collecting waste is fixedly connected to the side of the connecting frame away from the output end of the motor. A base is fixedly connected to the bottom of the inner surface of the control box. A collection mechanism for collecting waste is provided between the base and the two sets of collection frames.

[0009] Furthermore, a limiting plate is fixedly connected inside one set of the collection frames, and the cross-section of the limiting plate is trapezoidal. The limiting plate is hollow, and the inner diameter of the limiting plate gradually increases from the base toward the collection frame. A limiting mechanism for fixing the filter housing is provided inside another set of the collection frames.

[0010] Furthermore, the limiting mechanism includes a partition fixedly connected inside the collection frame, and the partition has a triangular cross-section. The inner diameter of the partition gradually increases from the base toward the collection frame, and the partition is hollow. Several sets of annular strips are fixedly connected at equal intervals on the outer surface of the partition, and the annular strips are made of rubber.

[0011] Furthermore, two sets of T-shaped columns are symmetrically and movably connected inside the collection frame corresponding to the partition. One end of each T-shaped column extends through to the outside of the collection frame and is movably connected thereto. A spring is provided on the outer part of the T-shaped column located outside the collection frame. One end of the spring is fixedly connected to the collection frame, and the other end is fixedly connected to the T-shaped column. An arc-shaped plate is fixedly connected to the inner end of the T-shaped column located inside the collection frame. Several sets of rectangular rubber strips are fixedly connected at equal intervals on the inner surface of the arc-shaped plate.

[0012] Furthermore, the collection mechanism includes a dustproof net fixedly connected inside the collection frame, and a connecting shaft is rotatably connected to one side of the inner surface of the collection frame. One end of the connecting shaft inside the collection frame is fixedly connected to a fan blade, and the other end extends through the interior of the connecting frame and is fixedly connected to a transmission wheel. A drive wheel is rotatably connected to the outer surface of the collection frame at one side of the transmission wheel, and a conveyor belt is connected between the drive wheel and the transmission wheel.

[0013] Furthermore, a gear is fixedly connected to one side of the drive wheel, and movable slots are provided on both sides of the upper outer surface of the base. A guide post is movably connected inside the movable slot, and one end of the guide post extends through to the outside of the movable slot and is fixedly connected to an internal gear ring. The internal gear ring corresponds to and meshes with the gear. A second spring is provided between the guide post and the movable slot, and both ends of the second spring are fixedly connected to both.

[0014] Furthermore, an arc-shaped seat is fixedly connected to the upper outer surface of the base, and a liquid storage chamber is provided inside the base, and a filter plate is provided inside the liquid storage chamber. The liquid storage chamber communicates with the inner surface of the arc-shaped seat.

[0015] Furthermore, a pressing head is provided on the upper outer surface of the filter plate, and a spray plate is provided at the top of the pressing head. The pressing head is connected to the liquid storage chamber, and the two ends of the spray plate are fixedly connected to two sets of internal toothed rings through movable blocks.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. In this invention, by setting two sets of collection frames and partitions and limiting plates on both sides of the base, and by using the partitions and limiting plates to abut against the open end and closed end of the filter body respectively, filter housings of different specifications can be fixed from both ends.

[0018] Furthermore, during the process of the filter housing and the partition plate coming into contact, the arc plate is squeezed by the filter housing and pushes the T-shaped column to both sides. Under the action of the spring, the arc plate further limits the filter housing from all sides. Thus, by using the arc plate, the partition plate and the limiting plate in cooperation, the filter housing can be limited in all directions, which improves the stability of the filter housing during the polishing process and improves the polishing quality.

[0019] 2. In this invention, by setting up a collection frame, a fan blade, and an internal gear ring to work together, during the process of the collection frame driving the filter housing to rotate and be polished, the internal gear ring drives the gear to drive the fan blade to rotate, accurately adsorbing the debris generated during the polishing process into the corresponding collection frame for collection, preventing debris from splashing into the interior of the operating equipment for a long time and affecting its operation, and adsorbing the debris during the polishing process.

[0020] Meanwhile, during the process of using the internal gear ring to drive the fan blades to rotate and adsorb debris, the gear reaction force can be used to move the spray plate up and down to squeeze the pressing head, so that the flushing coolant inside the liquid storage chamber is sprayed out through the spray plate to flush the surface of the filter housing. The debris drips onto the surface of the filter plate with the flushing liquid, cleaning the debris on the surface of the filter housing, avoiding the impact of residual debris on the filter surface on further grinding, and improving the grinding quality.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: As Figure 1 and Figure 2 As shown, the present invention proposes a rotary polishing device for the outer surface of a fuel filter housing, including an operation box 1. A guide rail 2 is provided inside the operation box 1 near the top, and a moving block 3 is movably connected to the outer surface of the guide rail 2. The moving block 3 is controlled to move along the guide rail 2 to the polishing area. An electric telescopic rod 4 is fixedly connected to the lower outer surface of the moving block 3.

[0031] Furthermore, one end of the electric telescopic rod 4 is fixedly connected to the moving block 3, and the other end is fixedly connected to a U-shaped frame 5. A grinding roller 6 is rotatably connected inside the U-shaped frame 5, and a motor 7 is set at a position corresponding to the grinding roller 6 on one side of the outer surface of the U-shaped frame 5. The output end of the motor 7 passes through the interior of the U-shaped frame 5 and is fixedly connected to the grinding roller 6, so that the electric push rod pushes the grinding roller 6 to move down and fit into the filter housing. The grinding roller 6 rotates with the output end of the motor 7 and grinds the filter housing.

[0032] Electric push rods 10 are provided on both sides of the inner surface of the control box 1. One end of the electric push rod 10 is fixedly connected to a connecting block. A motor 11 is provided on the outer surface of one side of the connecting block. A connecting frame 13 is fixedly connected to the output end of the motor 11. A collection frame 12 for collecting waste is fixedly connected to the side of the connecting frame 13 away from the output end of the motor 11. The two sets of electric push rods 10 move towards the filter housing to limit their movement. A base 14 is fixedly connected to the bottom of the inner surface of the control box 1.

[0033] Example 2: Figure 2-7 As shown, the difference between this embodiment and embodiment 1 is that a limiting plate 15 is fixedly connected inside a set of collection frames 12, and the cross-section of the limiting plate 15 is trapezoidal, the limiting plate 15 is hollow, and the inner diameter of the limiting plate 15 gradually increases from the base 14 toward the collection frame 12. The closed end of the filter housing abuts against the limiting plate 15. The other set of collection frames 12 is provided with a limiting mechanism 8 for fixing the filter housing.

[0034] The limiting mechanism 8 includes a partition 81 fixedly connected inside the collection frame 12. The partition 81 has a triangular cross-section. The inner diameter of the partition 81 gradually increases from the base 14 toward the collection frame 12. The partition 81 is hollow. Several sets of annular strips 82 are fixedly connected at equal intervals on the outer surface of the partition 81. The annular strips 82 are made of rubber. The open end of the filter housing abuts against the partition 81, and the annular strips 82 fit against the filter housing.

[0035] Two sets of T-shaped columns 83 are symmetrically and movably connected inside the collection frame 12 corresponding to the partition 81. One end of the T-shaped column 83 extends through to the outside of the collection frame 12 and is movably connected thereto. A spring 84 is provided on the outer part of the T-shaped column 83 located outside the collection frame 12. One end of the spring 84 is fixedly connected to the collection frame 12, and the other end is fixedly connected to the T-shaped column 83. An arc-shaped plate 85 is fixedly connected to the end of the T-shaped column 83 located inside the collection frame 12.

[0036] During the process of the filter housing and the partition plate 81 coming into contact, the arc plate 85 is squeezed by the filter housing and pushes the T-shaped column 83 to both sides. Under the action of the spring 84, the arc plate 85 is further limited from all sides of the filter housing. Several sets of rectangular rubber strips 86 are fixedly connected at equal intervals on the inner surface of the arc plate 85. The rectangular rubber strips 86 can increase the frictional resistance between the filter and the filter, and prevent the filter housing from rotating relative to the collection frame 12.

[0037] Example 3: Figure 2-6As shown, the difference between this embodiment and embodiments 1 and 2 is that a collection mechanism 9 for collecting waste is provided between the base 14 and the two sets of collection frames 12. The collection mechanism 9 includes a dustproof net 91 fixedly connected to the inside of the collection frame 12, and a connecting shaft is rotatably connected to one side of the inner surface of the collection frame 12. One end of the connecting shaft located inside the collection frame 12 is fixedly connected to a fan blade 92, and the other end passes through the inside of the connecting frame 13 and is fixedly connected to a transmission wheel 93. A drive wheel 94 is rotatably connected to the outer surface of the collection frame 12 located on one side of the transmission wheel 93, and a conveyor belt 95 is connected between the drive wheel 94 and the transmission wheel 93.

[0038] A gear 96 is fixedly connected to one side of the drive wheel 94, and movable slots are provided on both sides of the upper outer surface of the base 14. A guide post 97 is movably connected inside the movable slot, and one end of the guide post 97 extends through to the outside of the movable slot and is fixedly connected to an internal gear ring 98. The internal gear ring 98 corresponds to and meshes with the gear 96.

[0039] As the collection frame 12 moves toward the base 14, the gear 96 enters the corresponding internal gear ring 98 and meshes with it. As the collection frame 12 rotates, the gear 96 rotates inside the internal gear ring 98, causing the fan blade 92 to rotate. The suction surface of the fan blade 92 faces the dustproof net 91, and the fan blade 92 adsorbs the debris generated during the grinding process into the collection frame 12.

[0040] Example 4: Figure 2-6 As shown, the difference between this embodiment and embodiments 1, 2, and 3 is that a second spring 99 is provided between the guide post 97 and the movable groove, the internal gear ring 98 is always meshed with the teeth in the gear 96, and during the rotation of the gear 96, the internal gear ring 98 is driven up and down by the second spring 99 and the gear 96, and the two ends of the second spring 99 are fixedly connected to both of them respectively. An arc-shaped seat 910 is fixedly connected to the upper outer surface of the base 14, and a liquid storage chamber 911 is provided inside the base 14.

[0041] A filter plate 912 is installed inside the liquid storage chamber 911. The liquid storage chamber 911 is connected to the inner surface of the arc-shaped seat 910. A pressing head 913 is installed on the upper outer surface of the filter plate 912. A spray plate 914 is installed at the top of the pressing head 913. The pressing head 913 is connected to the liquid storage chamber 911. Both ends of the spray plate 914 are fixedly connected to two sets of internal gear rings 98 through movable blocks. The spray plate 914 moves up and down repeatedly to squeeze the pressing head 913, but the internal gear rings 98 are always engaged with the teeth in the gear 96. The flushing coolant inside the liquid storage chamber 911 flushes the surface of the filter housing. Debris drips onto the surface of the filter plate 912 with the flushing liquid, thereby further flushing the debris on the surface of the filter housing.

[0042] The working process and principle of this invention are as follows:

[0043] Step 1: Before polishing, place the filter housing on the surface of the arc plate 85. The length of the filter housing is greater than the length of the spray plate 914, so it will not fall into the liquid storage chamber 911, and make the open end of the filter housing correspond to the partition plate 81.

[0044] Step 2: Simultaneously control the two sets of electric push rods 10 to move closer to the filter housing. The closed end of the filter housing abuts against the limiting plate 15, and the open end of the filter housing abuts against the partition plate 81. The annular strip 82 fits against the filter housing. Therefore, the limiting plate 15 and the partition plate 81 cooperate with each other to fix filter housings of different specifications from both ends, ensuring the stability of the filter housing during the grinding process and improving the grinding quality.

[0045] Step 3: During the process of the filter housing and the partition plate 81 coming into contact, the arc plate 85 is squeezed by the filter housing and pushes the T-shaped column 83 to both sides. Under the action of the spring 84, the arc plate 85 further limits the filter housing from all sides. The rectangular rubber strip 86 can increase the frictional resistance between the filter and the filter, and prevent the filter housing and the collection frame 12 from rotating relative to each other.

[0046] Step 4: As the collection frame 12 moves toward the base 14, the gear 96 enters the corresponding internal gear ring 98 and meshes with it. The moving block 3 is controlled to move along the guide rail 2 to the area to be polished, so that the electric push rod pushes the polishing roller 6 down and fits against the filter housing. Then, the motor 1 7 and the motor 2 11 are controlled to run at the same time. The polishing roller 6 rotates with the output end of the motor 1 7 and polishes the filter housing. The motor 2 11 drives the collection frame 12 and the filter body to rotate.

[0047] Step 5: During the rotation of the collection frame 12, as the gear 96 rotates inside the internal gear ring 98, the gear 96 drives the fan blade 92 to rotate. The suction surface of the fan blade 92 faces the dustproof net 91, so the fan blade 92 adsorbs the debris during the grinding process. During the rotation of the gear 96, the internal gear ring 98 is driven by the spring 99 and the gear 96 to drive the spray plate 914 to move up and down repeatedly to squeeze the pressing head 913. However, the internal gear ring 98 is always engaged with the teeth inside the gear 96. The flushing coolant inside the liquid storage chamber 911 flushes the surface of the filter housing. The debris drips onto the surface of the filter plate 912 with the flushing liquid, further flushing the debris on the surface of the filter housing. After the grinding is completed, the debris on the surface of the filter plate 912 and inside the collection frame 12 is cleaned.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
