Description

Technical Field

[0001] The invention relates to the technical field of profile cleaning, and in particular to a profile surface cleaning device. Background Art

[0002] During the processing of profiles, impurities such as oil, rust, and scale will appear on the surface, which seriously affect the appearance quality and performance of the profiles. Therefore, after the profile processing is completed, the surface of the profile needs to be cleaned to remove impurities on the profile surface. The profile surface after cleaning is cleaner, which is conducive to improving the adhesion of the coating and facilitating the subsequent surface spraying of the profile to ensure the anti-corrosion performance and appearance quality of the profile.

[0003] Referring to the Chinese patent document with the authorization announcement number CN213738280U and the announcement date July 20, 2021, the name is a profile cleaning system, which includes a lifting assembly, a swing rod, a clamping assembly and a cleaning tank. The clamping assembly is arranged on the swing rod, and the clamping assembly is used to clamp the profile. When cleaning the profile, the swing rod is driven up or down by the lifting assembly, so that the swing rod and the profile are immersed in the cleaning tank for cleaning.

[0004] Since the surface shape of the profile is complex and there are multiple through grooves of different shapes, in order to promote the flow of cleaning liquid and facilitate the discharge of waste water after cleaning, the profile is currently mostly cleaned in an inclined manner.

[0005] With respect to the above-mentioned related technologies, the contact position between the profile and the clamping assembly is difficult to be cleaned by the cleaning liquid, resulting in incomplete cleaning of the profile; and the various profiles currently on the market have complex shapes and different sizes, and there are multiple grooves of different shapes in the profile, which makes it difficult for the cleaning liquid to fully flow into and out of the grooves, resulting in incomplete cleaning, the existence of dead corners for cleaning, and the problem that dirt and cleaning liquid are difficult to discharge. Summary of the invention

[0006] In view of this, the present invention provides a profile surface cleaning device, aiming to solve the technical problems in the prior art that there are cleaning dead corners, dirt and cleaning liquid are difficult to discharge, and the cleaning effect is not ideal.

[0007] In order to solve the above technical problems, the present invention provides a profile surface cleaning device, which adopts the following technical scheme: a profile surface cleaning device, including a cleaning pool and a lifting beam, a placing frame is connected below the lifting beam, and a plurality of swing rods are arranged in sequence from top to bottom on both sides of the placing frame; the swing rod is rotatably connected to the placing frame through a horizontally placed hinge shaft, and a swing assembly for controlling the swing rod to swing around the central axis of the hinge shaft is provided on the lifting beam; both ends of the swing rod are connected to a horizontally placed mounting shaft, and a plurality of support rollers that can support the bottom surface of the end of the profile are rotatably sleeved on the mounting shaft, a clockwork spring is provided between the support roller and the mounting shaft, a support rod is connected between the two mounting shafts, and the support rod is provided with a limiting roller that can abut against the top surface of the middle part of the profile and a limiting member that can control the limiting roller to abut or separate from the profile.

[0008] By adopting the above technical scheme, through the hinge shaft, moving rod and pulling rod, when the moving rod moves back and forth vertically, the swing rod can swing around the central axis of the hinge shaft, so that the two ends of the profile move up alternately. The cleaning method of the profile swinging up and down in the cleaning tank can promote the cleaning liquid to enter the interior of the through groove, improve the comprehensiveness of cleaning, and also enhance the fluidity and impact force of the cleaning liquid, which helps to flush away dirt and impurities from the surface of the profile and the through groove, can improve the situation of cleaning dead corners, and enhance the cleaning effect of the device.

[0009] A structure is used to limit the position of the profile using supporting rollers and limiting rollers. As the profile swings, the profile slides to the left or right end under the action of the profile's gravity. During the sliding process, the profile and the supporting rollers and limiting rollers move relative to each other, changing the contact surfaces of the supporting rollers, limiting rollers and the profile, further reducing cleaning dead angles and improving the cleaning effect of the device. A clockwork spring is provided to limit the number of rotations of the supporting roller, thereby limiting the relative displacement of the profile and the supporting roller, improving the stability of the device and avoiding the profile from accidentally slipping off the supporting roller as much as possible.

[0010] The structure using two supporting rollers to support both ends of the profile is conducive to the removal of the profile. Compared with the previous method in which both ends of the profile are fixed by clamping components, the profile is not easy to conflict with the structure when being taken, and has better stability.

[0011] Optionally, the swing assembly includes a moving rod arranged below the lifting beam, the lifting beam is provided with a moving part capable of controlling the vertical reciprocating movement of the moving rod, a pull rod is provided between the moving rod and the hinge shaft, and the left end of the pull rod is slidably connected to the moving rod in the horizontal direction.

[0012] Optionally, the left end of the pull rod is connected to a rotating block, the moving rod is provided with a sliding groove extending horizontally for the rotating block to slide, and the placement frame is provided with a rotating groove for the right end of the pull rod to rotate.

[0013] Optionally, multiple fixed shafts are arranged in sequence from top to bottom on both sides of the moving rod, a swing blade is rotatably sleeved on the fixed shaft, a fixed rod is fixedly connected to the middle of the left side of the fixed shaft, and a fixed groove is opened on the left side of the swing blade for the fixed rod to slide, and the fixed groove is used to limit the swing angle of the swing blade so that the swing blade always remains in a state of being tilted downward from left to right.

[0014] By adopting the above technical solution, a swinging blade is set. As the moving rod moves back and forth vertically, under the pushing action of the moving rod and the buoyancy of the cleaning liquid, the swinging blade swings up and down, and the swinging direction is limited. The swinging blade makes the cleaning liquid tend to move in the lower right direction.

[0015] When the swing blades swing up and down, they can drive the cleaning liquid in the cleaning pool to flow, increase the kinetic energy of the cleaning liquid, thereby enhancing the impact force on the surface of the profile, helping to remove stubborn stains, and also making the cleaning liquid more evenly distributed, improving the uniformity of cleaning. Since the flow of the cleaning liquid is accelerated, the cleaning efficiency of the device can also be improved, saving the space occupied by the device.

[0016] Optionally, the support rollers at corresponding positions on the two mounting shafts form a group of support rollers, and the multiple groups of support rollers on the mounting shafts are arranged at intervals with the multiple support rods.

[0017] By adopting the above technical solution, multiple groups of support rollers are arranged at intervals with multiple support rods, that is, a support rod is provided between each two adjacent groups of support rollers, so that the limiting rollers and limiting members on the same support rod can limit the profiles on both sides of the support rod, which is beneficial to the installation of the structure, saves device space, and improves the stability of the device.

[0018] Optionally, a vertical rod is fixedly connected to the support rod, a rotating ring is detachably connected to the top of the vertical rod, and two symmetrically arranged limiting rollers are connected to the rotating ring.

[0019] By adopting the above technical solution, the two limiting rollers respectively limit the profiles on both sides of the support rod, which is convenient for operation.

[0020] Optionally, the limiting member includes a limiting bolt, which is threadedly connected to the inner wall of the rotating ring and the top of the vertical rod in sequence, and the top of the limiting bolt can abut against the top surface of the rotating ring.

[0021] By adopting the above technical solution, the position of the rotating ring relative to the vertical rod can be limited by rotating the limit bolt, which is convenient for use.

[0022] Optionally, the bottom surface of the rotating ring is connected to a plurality of circumferentially arranged protrusions, the top end of the vertical rod is provided with a plurality of grooves corresponding to the protrusions one by one, and the protrusions are slidably inserted into the inner walls of the grooves.

[0023] By adopting the above technical solution, the setting of the protrusions and the grooves is conducive to improving the stability of the device and avoiding as much as possible the accidental displacement of the rotating ring and the limiting roller during the operation of the device.

[0024] Optionally, both ends of the support roller are fixedly sleeved with limiting rings capable of abutting against the side walls of the profile.

[0025] By adopting the above technical solution, the limiting ring limits the position of the profile, thereby improving the stability of the device.

[0026] In summary, the present invention includes the following beneficial technical effects: 1. The cleaning method of profile swinging is adopted to promote the cleaning liquid to enter the interior of the profile, improve the comprehensiveness of cleaning, reduce the existence of cleaning dead corners, enhance the fluidity and impact force of the cleaning liquid, help to clean and discharge dirt, and improve the cleaning effect of the device. When the profile swings, the profile slides back and forth left and right, which can change the contact position between the profile and the device, further reduce the cleaning dead corners of the device, and use support rollers as support to facilitate the removal of the profile and easy use.

[0027] 2. The swing blades swing up and down, which can drive the cleaning liquid in the cleaning pool to flow, increase the kinetic energy of the cleaning liquid, thereby enhancing the impact force on the surface of the profile, helping to remove stubborn stains, and can also make the cleaning liquid more evenly distributed, improving the uniformity of cleaning. Since the flow of the cleaning liquid is accelerated, the cleaning efficiency of the device can also be improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0031] The following is combined with Figure 1 -Attached Figure 6 The present invention is described in further detail.

[0032] The embodiment of the present invention discloses a profile surface cleaning device. Figures 1 to 6 A profile surface cleaning device includes a cleaning tank 1, a hoisting beam 2, a support, a swing assembly 6 and a clamping assembly 7.

[0033] Reference Figure 1 There are multiple cleaning pools 1, which are arranged in sequence. Different cleaning liquids are contained in the multiple cleaning pools 1. The profile 9 is cleaned by the cleaning liquids in the multiple cleaning pools 1 in sequence, so as to remove the oil and dirt on the surface of the profile 9. The hoisting beam 2 is horizontally arranged above the cleaning pool 1. Support frames 21 for supporting the hoisting beam 2 are arranged on both sides of the cleaning pool 1. When in use, the vertical reciprocating movement and translation of the hoisting beam 2 are controlled by an external hoisting device, such as a crane.

[0034] Reference Figure 2 , Figure 3 and Figure 4, the support is arranged below the hoisting beam 2, and the support includes a placement frame 3, a swing rod 4 and a hinge shaft 5. The placement frame 3 is arranged vertically, and the placement frame 3 extends into the interior of the cleaning tank 1. There are multiple swing rods 4, and the multiple swing rods 4 are divided into two groups. The two groups of swing rods 4 are respectively connected to the two sides of the placement frame 3. The multiple swing rods 4 of each group of swing rods 4 are arranged in sequence from top to bottom, which is conducive to keeping the device balanced. The hinge shaft 5 is arranged horizontally, and there are multiple hinge shafts 5. Each hinge shaft 5 is penetrated by the placement frame 3 in a rotating connection. The two ends of the hinge shaft 5 are fixedly connected to the swing rods 4 located on both sides of the placement frame 3 in turn, so that the swing rod 4 swings around the central axis of the hinge shaft 5 as a reference, and the rotation of the same hinge shaft 5 can control the two swing rods 4 located on both sides of the placement frame 3 to swing synchronously, which is convenient for use.

[0035] The swing rod 4 swings, driving the profile 9 on the swing rod 4 to swing. The cleaning method of the swinging profile 9 can promote the cleaning liquid to enter the interior of the through groove, improve the comprehensiveness of cleaning, and also enhance the fluidity and impact force of the cleaning liquid, which helps to flush away dirt and impurities from the surface of the profile 9 and the through groove, and can improve the situation of cleaning dead corners and enhance the cleaning effect of the device.

[0036] Reference Figure 3 and Figure 4 The swing assembly 6 is used to control the swing rod 4 to swing around the central axis of the hinge shaft 5. The swing assembly 6 includes a moving rod 61, a moving member 62 and a pull rod 63.

[0037] The moving rod 61 is arranged below the hoisting beam 2, and the moving member 62 is arranged on the hoisting beam 2. The moving member 62 can control the vertical reciprocating movement of the moving rod 61. A plurality of pull rods 63 are provided, and the plurality of pull rods 63 correspond to the plurality of swing rods 4 one by one. The left end of the pull rod 63 is slidably connected to the moving rod 61 along the left-right direction, and the right end of the pull rod 63 passes through the placement frame 3 and is connected to the hinge shaft 5.

[0038] The moving member 62 controls the moving rod 61 to move back and forth vertically. During the movement, the pull rod 63 pulls the hinge shaft 5 to make the hinge shaft 5 swing.

[0039] It is convenient to control the swing range and direction of the swing arm 4, and to synchronously control the swing of multiple hinge shafts 5. It can avoid conflicts between multiple swing arms 4 and multiple profiles 9 as much as possible, which is beneficial to improving the stability of the device and ensuring the normal operation of the device.

[0040] Specifically, the moving part 62 can be a linear output element such as a linear motor or a linear cylinder to drive the vertical reciprocating movement of the moving rod 61. Due to the limitations of the use environment, when selecting a specific model, a linear drive element suitable for use in a humid environment is selected as the moving part 62 in this embodiment.

[0041] Reference Figure 4and Figure 5 Specifically, the left end of each pull rod 63 is connected to a rotating block 631, the moving rod 61 is provided with a plurality of sliding grooves 632, the plurality of sliding grooves 632 correspond to the plurality of pull rods 63 one by one, the sliding grooves 632 extend in the horizontal direction, the sliding grooves 632 are provided for the sliding of the rotating block 631, the placement frame 3 is provided with a plurality of rotating grooves 633, the plurality of rotating grooves 633 correspond to the plurality of pull rods 63 one by one, and the rotating grooves 633 are provided for the right end of the pull rod 63 to rotate. Avoid conflicts between structures as much as possible to ensure the normal operation of the device, so that when the moving rod 61 moves back and forth vertically, the pull rod 63 pulls the hinge shaft 5, so that the hinge shaft 5 and the swing rod 4 swing around the central axis of the hinge shaft 5.

[0042] Reference Figure 2 and Figure 3 The clamping assembly 7 is used to limit the position of the profile 9 relative to the swing rod 4. Each swing rod 4 is provided with a set of clamping assemblies 7. The clamping assembly 7 includes a mounting shaft 71, a supporting roller 72, a spring spring, a supporting rod 73, a limiting roller 74 and a limiting member 75.

[0043] The installation shaft 71 is placed horizontally, and two installation shafts 71 are provided. The two installation shafts 71 are arranged in parallel, and the two installation shafts 71 are respectively connected to the two ends of the swing rod 4. The installation shafts 71 play a supporting role, which is convenient for installing other structures.

[0044] There are multiple support rollers 72, and each installation shaft 71 is rotatably sleeved with multiple support rollers 72. The support rollers 72 are used to support the ends of the profile 9. The support rollers 72 are connected to the bottom surface of the profile 9. Specifically, the support rollers 72 at corresponding positions on the two installation shafts 71 form a group of support rollers 72, and a group of support rollers 72 supports the two ends of a profile 9.

[0045] The spring is disposed between the supporting roller 72 and the mounting shaft 71, and the spring can limit the number of rotations of the supporting roller 72. The spring is not shown in the figure.

[0046] The support rod 73 is disposed between the two mounting shafts 71 , and the support rod 73 plays a supporting role and is used for mounting other structures.

[0047] The limiting roller 74 is arranged on the support rod 73 , and the limiting roller 74 can abut against the top surface of the middle part of the profile 9 . The limiting roller 74 cooperates with the two supporting rollers 72 to limit the position of the profile 9 , so as to facilitate the movement of the profile 9 .

[0048] The limiting member 75 is disposed on the support rod 73 , and the limiting member 75 is used to change the position of the limiting roller 74 to facilitate the taking of the profile 9 .

[0049] A structure is used to limit the profile 9 by using supporting rollers 72 and limiting rollers 74. As the profile 9 swings, the profile 9 slides to the left or right end under the action of gravity of the profile 9. During the sliding process, the profile 9, the supporting rollers 72 and the limiting rollers 74 move relative to each other, thereby changing the contact surfaces of the supporting rollers 72 and the limiting rollers 74 with the profile 9, further reducing blind spots for cleaning and improving the cleaning effect of the device. A clockwork spring is provided to limit the number of rotations of the supporting rollers 72, thereby limiting the relative displacement of the profile 9 and the supporting rollers 72, improving the stability of the device and avoiding the profile 9 from accidentally slipping off the supporting rollers 72 as much as possible.

[0050] Furthermore, the structure of using two supporting rollers 72 to support both ends of the profile 9 is conducive to taking the profile 9. Compared with the previous method in which both ends of the profile 9 are fixed by the clamping assembly 7, the profile 9 is not easy to conflict with the structure when taking it, and has better stability.

[0051] Specifically, both ends of the support roller 72 are fixedly sleeved with a limiting ring, and the limiting ring abuts against the side wall of the profile 9. The limiting ring limits the position of the profile 9, which is conducive to improving the stability of the device.

[0052] Specifically, the multiple groups of support rollers 72 on the mounting shaft 71 are arranged at intervals with the multiple support rods 73. That is, a support rod 73 is provided between each two adjacent groups of support rollers 72, so that the multiple limiting rollers 74 and limiting members 75 on the same support rod 73 can limit the profiles 9 on both sides of the support rod 73, which is beneficial to the installation of the structure, saves the device space, and improves the stability of the device. Specifically, each support rod 73 is provided with a group of limiting members 75, each support rod 73 is provided with two limiting rollers 74, and a group of limiting members 75 can synchronously control the movement of the two limiting rollers 74.

[0053] Reference Figure 6 The limiting member 75 includes a vertical rod 751 , a rotating ring 752 , a limiting bolt 753 , a protrusion 754 and a groove 755 .

[0054] The vertical rod 751 is vertically arranged and fixedly connected to the top surface of the support rod 73. The rotating ring 752 is detachably connected to the top of the vertical rod 751, and the two limiting rollers 74 are symmetrically arranged and fixedly connected to the side wall of the rotating ring 752. The limiting bolt 753 is sequentially penetrated through the inner wall of the rotating ring 752 and the top of the vertical rod 751 in a threaded connection manner, and the top of the limiting bolt 753 can abut against the top surface of the rotating ring 752.

[0055] The limiting bolt 753 is rotated and moved upward until the limiting bolt 753 is separated from the vertical rod 751, and the rotating ring 752 is rotated to change the position of the limiting roller 74. After the rotation is completed, the limiting bolt 753 is installed so that the limiting bolt 753 is threadedly connected to the inner wall of the rotating ring 752 and the top of the vertical rod 751 in sequence, thereby limiting the position of the rotating ring 752 relative to the vertical rod 751. The structure is simple and easy to operate.

[0056] There are multiple protrusions 754, which are evenly arranged along the circumference of the rotating ring 752. The multiple protrusions 754 are fixedly connected to the bottom surface of the rotating ring 752. There are multiple grooves 755, which are opened on the top surface of the vertical rod 751. The multiple grooves 755 correspond to the multiple protrusions 754 one by one, and the protrusions 754 are slidably inserted into the inner walls of the grooves 755.

[0057] The arrangement of the protrusion 754 and the groove 755 is conducive to improving the stability of the device and avoiding as much as possible the accidental displacement of the rotating ring 752 and the limiting roller 74 due to other external forces during the operation of the device.

[0058] Reference Figure 3 and Figure 5 Furthermore, a plurality of swing blades 8 are provided on the moving rod 61. A plurality of fixed shafts 81 are arranged in sequence from top to bottom on both sides of the moving rod 61, and the swing blades 8 are sleeved on the fixed shafts 81. A fixed rod 82 is fixedly connected to the middle of the left side of the fixed shaft 81, and a fixed groove 83 for the fixed rod 82 to slide is provided on the left side of the swing blade 8. The fixed groove 83 is used to limit the swing angle of the swing blade 8 so that the swing blade 8 always maintains a state of being tilted downward from left to right.

[0059] As the moving rod 61 moves back and forth vertically, under the driving force of the moving rod 61 and the buoyancy of the cleaning liquid, the swing blade 8 swings up and down, and the swinging direction is limited. The swing blade 8 makes the cleaning liquid have a tendency to move in the lower right direction. When the swing blade 8 swings up and down, it can drive the cleaning liquid in the cleaning tank 1 to flow, increase the kinetic energy of the cleaning liquid, thereby enhancing the impact force on the surface of the profile 9, which is helpful to remove stubborn stains, and can also make the cleaning liquid more evenly distributed, improve the uniformity of cleaning, and because the flow of the cleaning liquid is accelerated, it can also improve the cleaning efficiency of the device and save the space occupied by the device.

[0060] The implementation principle of a profile surface cleaning device according to an embodiment of the present invention is as follows: The limiting bolt 753 is rotated to separate the limiting bolt 753 from the vertical rod 751, the rotating ring 752 is rotated to change the position of the limiting roller 74, and the profile 9 is placed on the supporting roller 72. The rotating ring 752 is rotated to make the limiting roller 74 correspond to the profile 9 in the vertical direction, and the protrusion 754 is slidably inserted into the groove 755. The limiting roller 74 abuts against the top surface of the middle part of the profile 9. The limiting bolt 753 is rotated to limit the position of the rotating ring 752. The supporting roller 72 cooperates with the limiting roller 74 to limit the position of the profile 9, thereby completing the loading and clamping of the profile 9.

[0061] After the profile 9 is clamped, the lifting beam 2 is moved, and the placement frame 3 and the swing rod 4 are immersed in the cleaning tank 1. During the immersion process, the moving rod 61 is controlled by the moving member 62 to move back and forth vertically, driving the multiple hinge shafts 5 to swing, thereby realizing the synchronous swinging of multiple profiles 9. After being immersed in the cleaning tank 1, the moving rod 61 moves back and forth vertically. It promotes the cleaning liquid to enter the interior of the through groove, improves the comprehensiveness of cleaning, and can also enhance the fluidity and impact force of the cleaning liquid, which helps to flush away dirt and impurities from the surface of the profile 9 and the through groove, and can improve the situation of cleaning dead corners and enhance the cleaning effect of the device. In the process of pulling the lifting beam 2 upward, the moving rod 61 moves back and forth vertically to promote the outflow of the cleaning liquid in the profile 9.

[0062] After cleaning is completed, the limiting bolt 753 is rotated to release the restriction of the limiting roller 74 on the profile 9, and the profile 9 is removed, thereby completing the unloading of the profile 9.

[0063] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
