Description

Technical Field

[0001] The invention relates to the technical field of aluminum-plastic plate degreasing and cleaning devices, in particular to a spray degreasing device used for aluminum-plastic plate processing. Background Art

[0002] In the production process of aluminum-plastic panels, the surface will be contaminated with grease due to various factors such as raw materials, production equipment or production environment. Degreasing is an important pretreatment step in the processing of aluminum-plastic panels, which affects the quality of subsequent processing. Traditional degreasing methods rely on manual labor, which is costly, inefficient and has safety risks.

[0003] Chinese patent application document CN113073333A discloses a spray degreasing device for aluminum-plastic panel processing. The aluminum-plastic panel is positioned on the inner side of the installation frame, and the clamping force of the clamping block is conveniently adjusted under the telescopic action of the reset rod. Under the action of the clamping block, the aluminum-plastic panel can be effectively positioned and fixed. With the rotation of the rotating shaft, the aluminum-plastic panel can be effectively processed in multiple directions. Elastic fibers are arranged inside the cleaning fibers, and connecting beads are fixedly installed at the bottom of the elastic fibers. The strong elastic force can effectively prevent the internal holes of the anti-blocking panel from being blocked. With the rotation of the connecting rod, the cleaning effect can be effectively achieved. The interior of the connecting beads is a hollow structure, and the nozzle rotates inside the spray block through the connecting beads, which is convenient for multi-angle adjustment and can effectively achieve the effect of full spraying.

[0004] However, in the actual use of the device, the device still only relies on the natural contact between the degreasing agent and the aluminum-plastic plate to degrease the aluminum-plastic plate, and cannot promote its dissolution and reaction rate. At the same time, it relies on manual placement and removal. The degreasing agent will cause more or less harm to the human body in the long run, and has certain safety hazards.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1: Figure 1 and Figure 2 As shown, a spray degreasing device for aluminum-plastic plate processing comprises a device shell 1, a feeding conveyor belt 11 and a discharging conveyor belt 12 are respectively arranged at the front and rear parts of the inner cavity of the device shell 1, clamping arm circulation structures 5 are symmetrically arranged on the left and right sides of the inner surface of the device shell 1, and a plurality of aluminum-plastic plate fixing structures 6 are arranged on the inner surfaces of the two clamping arm circulation structures 5 in a curved distribution, synchronous belts 4 that are transmission-connected to the adjacent clamping arm circulation structures 5 are arranged at both ends of the device shell 1, and a driving structure 3 is commonly arranged at one end of the two synchronous belts 4 away from the clamping arm circulation structures 5, and a driving motor 2 that is fixedly connected to the ground through a motor bracket is fixedly connected to the input end of the driving structure 3, a degreasing agent storage tank 7 is opened at the front part of the inner cavity of the device shell 1, and a spray cleaning structure 8 is arranged at the part of the inner cavity of the device shell 1 located at the rear side of the degreasing agent storage tank 7.

[0038] It should be noted that the above-mentioned feed conveyor belt 11 and discharge conveyor belt 12 are both conventional material conveying structures in the prior art. In the present invention, their basic functions of conveying and carrying materials are utilized, and their internal principles, structures and control methods are not described in detail.

[0039] Specifically, to achieve the spray cleaning function, refer to Figure 3 The spray cleaning structure 8 includes two spray pipes 81 fixedly connected to the inner wall of the device shell 1, and the inner surface of the device shell 1 on the front side of the two spray pipes 81 is rotatably connected with a scrubbing roller 82. A sewage pool 83 is opened on the bottom wall of the inner cavity of the device shell 1 located below the spray pipes 81 and the scrubbing roller 82, and the sewage pool 83 is connected to the sewage pipe through a drain pipe.

[0040] The spray pipe 81 is connected to an external clean water tank, and clean water is continuously supplied to the spray pipe 81 to rinse the degreasing agent on the aluminum-plastic plate and clean it through the scrubbing roller 82. After spraying and rinsing both sides of the aluminum-plastic plate, it is sent out through the discharge conveyor belt 12 at the rear side.

[0041] During the operation of this embodiment, the aluminum-plastic plate is first fed into the device housing 1 at a certain frequency through the feed conveyor belt 11, and the aluminum-plastic plate fixing structure 6 is driven to move periodically through the clamp arm circulation structure 5 to drive the aluminum-plastic plate to be immersed and turned in the degreasing agent storage tank 7 to make it fully infiltrated and fully react with the degreasing agent in the degreasing agent storage tank 7. After that, it is sprayed through the spray pipe 81 and rinsed with the scrubbing roller 82. After the rinsing is completed, it is sent out by the discharge conveyor belt 12, so as to realize continuous and automatic degreasing, reduce the participation of personnel, improve the degreasing efficiency, reduce the residual chemical reagents on the surface of the aluminum-plastic plate, and improve the product quality.

[0042] Embodiment 2: Based on Embodiment 1, this embodiment drives the aluminum-plastic plate fixing structure 6 and the aluminum-plastic plate clamped by the aluminum-plastic plate fixing structure 6 to move periodically in the device housing 1 through the driving part 52 arranged in the guide groove 51, and utilizes the cooperation of the limit plate 524 and the aluminum-plastic plate fixing structure 6 to enable the aluminum-plastic plate to move and continuously flip in the degreasing agent storage groove 7, so that the degreasing agent contacted by the aluminum-plastic plate circulates on the surface of the aluminum-plastic plate and promotes it to react with the grease on the surface of the aluminum-plastic plate, fully dissolves the grease on the surface of the aluminum-plastic plate, and improves product quality.

[0043] Specifically, in order to guide the aluminum-plastic plate to move in the device housing 1, refer to Figure 3 , Figure 4 and Figure 5The clamp arm circulation structure 5 includes guide grooves 51 symmetrically opened on the inner surface of the device shell 1. The inner surfaces of the two guide grooves 51 are provided with driving parts 52. The outer surface of the driving part 52 is rotatably connected to the adjacent aluminum-plastic plate fixing structure 6. The inner surface of the device shell 1 is located at the lower guide groove 51. Both sides are symmetrically fixed with guide plates 53 with the same trajectory as the guide groove 51.

[0044] Further, in order to drive the aluminum-plastic plate to fully immerse the degreasing agent in the degreasing agent storage tank 7, refer to Figure 4 The guide groove 51 is an annular track, the lower part of which is located on the upper side of the degreaser storage groove 7 and extends downward into the degreaser storage groove 7 in a trapezoidal shape and returns to the horizontal track from the rear side of the degreaser storage groove 7 upward.

[0045] In summary, the guide groove 51 can be divided into two parts, a horizontal part and a trapezoidal part. The trapezoidal part is located in the area where the degreaser storage groove 7 is located, and is used to drive the aluminum-plastic plate fixing structure 6 and the aluminum-plastic plate clamped therein into the degreaser in the degreaser storage groove 7. The degreaser filled in the degreaser storage groove 7 can react with the grease on the surface of the aluminum-plastic plate to dissolve it in the degreaser, thereby reducing the grease residue on the surface of the aluminum-plastic plate.

[0046] The degreasing agent used is a conventional surfactant, such as polyvinyl pyrrolidone PVP, polyethylene glycol PEG, sodium dodecyl sulfate SDS, etc., which has less harm to the environment and has a faster reaction rate;

[0047] The guide groove 51 can make the aluminum-plastic plate fixing structure 6 turn over continuously in the degreasing agent storage tank 7, so as to mobilize the aluminum-plastic plate to rotate continuously in the degreasing agent storage tank 7, and stir the degreasing agent in the degreasing agent storage tank 7 to flow greatly, thereby accelerating its reaction rate.

[0048] Further, in order to drive the aluminum-plastic plate fixing structure 6 to move in the guide groove 51 so as to drive the aluminum-plastic plate to move in the device housing 1, refer to Figure 6 and Figure 7 The driving part 52 includes a driving belt 522 wound around the inner surface of the guide groove 51, and the left and right sides of the inner surface of the driving belt 522 are wound with driving wheels 521 connected to the adjacent synchronous belt 4. The outer surface of the driving belt 522 is fixedly connected with a plurality of supporting plates 523 rotatably connected to the aluminum-plastic plate fixing structure 6 in a curved distribution. The driving part 52 also includes a limiting plate 524 fixedly connected to the inner surface of the guide groove 51 away from the driving belt 522.

[0049] First, it should be noted that the synchronous belts 4 on both sides can achieve synchronous and unidirectional rotation through the action of the driving structure 3, thereby driving the driving wheels 521 on both sides to run synchronously, thereby ensuring the synchronous movement of the aluminum-plastic panel fixing structures 6 on both sides of the same aluminum-plastic panel.

[0050] When the driving wheel 521 is driven by the synchronous belt 4 to drive the driving belt 522 to move periodically, the driving belt 522 will drive the aluminum-plastic panel fixing structure 6 to move through the support plate 523 during the movement, thereby driving the aluminum-plastic panel to move along a predetermined trajectory.

[0051] Embodiment 3: Based on Embodiment 2, this embodiment drives the aluminum-plastic plate to rotate in the degreasing agent storage tank 7 through the cooperation of the driving component 61 in the aluminum-plastic plate fixing structure 6, the limit plate 524, and the tooth groove 525, and cooperates with the action of the spray pipe 81 and the scrubbing roller 82 to spray and scrub both sides of the aluminum-plastic plate, thereby improving the cleaning efficiency and quality, reducing the grease and degreasing agent residue on the surface of the aluminum-plastic plate, and improving product quality.

[0052] Specifically, to achieve the clamping and fixing of the aluminum-plastic panel, refer to Figure 7 The aluminum-plastic plate fixing structure 6 includes a driving component 61 that is slidably connected to the inner surface of the guide groove 51. A convex connecting shaft 62 is fixedly connected to the side of the driving component 61 close to the inner cavity of the device housing 1. A pressing component 63 is symmetrically arranged on the outer surface of the convex connecting shaft 62, and a clamping component 64 is symmetrically arranged on the front of the outer surface of the convex connecting shaft 62.

[0053] The driving assembly 61 can drive the aluminum-plastic plate fixing structure 6 to move along the predetermined track of the guide groove 51 under the action of the driving belt 522 and the supporting plate 523. At the same time, the limiting plate 524 and the tooth groove 525 can be used to drive the aluminum-plastic plate to flip at a predetermined position, so that the degreasing agent or the cleaning structure can act on all surfaces of the aluminum-plastic plate, thereby improving the degreasing efficiency.

[0054] Further, in order to drive the aluminum-plastic panel to move in the device housing 1 into the area where the degreasing agent storage tank 7 and the spray cleaning structure 8 are located for spray degreasing, refer to Fig. 9 , Fig.10 , Fig.11 and Fig.12 The driving assembly 61 includes a pulley 611 which is slidably connected to the inner surface of the guide groove 51, the outer surface of the inner central axis of the pulley 611 is rotatably connected to the inner surface of the adjacent support plate 523, the central axis of the pulley 611 is fixedly connected to a gear 612, and the outer ring of the teeth of the gear 612 is rotatably connected to a pulley 2 613; a limiting plate 524 is located at the inner side of the degreaser storage groove 7 and is provided with a plurality of tooth grooves 525, and a portion of the limiting plate 524 located between the two spray pipes 81 is provided with tooth grooves 525.

[0055] The pulley 1 611 slides inside the guide groove 51, and when the gear 612 contacts the limiting plate 1 524, the teeth on both sides thereof slide on the surface of the limiting plate 1 524 through the pulley 2 613, and the pulley 1 611 does not rotate at this time. When the gear 612 contacts the tooth groove 525, the pulley 1 611 is driven to rotate through the gear 612 due to the meshing action of the tooth groove 525 and the gear 612, thereby driving the clamping assembly 64 to rotate through the convex connecting shaft 62, thereby driving the aluminum-plastic plate to rotate at the corresponding position of the degreasing agent storage tank 7 or the spray cleaning structure 8;

[0056] It should be particularly noted that one of the areas where the tooth grooves 525 are located is the action area of ​​the degreasing agent storage tank 7, that is, the area where the guide groove 51 is trapezoidal. The tooth grooves 525 are arranged along the entire path, so that the aluminum-plastic plate can start to rotate slowly after entering the degreasing agent in the degreasing agent storage tank 7, stirring the degreasing agent to make it flow on the surface of the aluminum-plastic plate, promoting the reaction between the degreasing agent and the grease on the surface of the aluminum-plastic plate, and improving the reaction rate. At the same time, part of the grease can be taken away by the flow and stirring effects, promoting the activation of the grease and detaching from the surface of the aluminum-plastic plate;

[0057] The second is located between the two groups of spray pipes 81 and the scrubbing rollers 82. When the trapezoidal area of ​​the guide groove 51 returns to the horizontal area, the tooth grooves 525 set will make the aluminum-plastic plate just in a horizontal state, and after being sprayed and scrubbed by the first coarse spray pipe 81 and the scrubbing roller 82, it is turned to the other side through this group of tooth grooves 525, and then the other side is sprayed and cleaned through the second group of spray pipes 81 and the scrubbing roller 82.

[0058] Further, in order to cooperate with the guide plate 53 to drive the two clamping components 64 to clamp the aluminum-plastic plate, refer to Fig.13 and Fig.14 The pressing assembly 63 includes pressing blocks 631 symmetrically distributed in the upper and lower parts. The two pressing blocks 631 are provided with a sliding groove 635 at one end close to the convex connecting shaft 62. The convex connecting shaft 62 is provided with an annular groove 634 at one end close to the pressing block 631. The inner surface of the annular groove 634 is slidably connected with a limit plate 2 633 symmetrically connected to the upper and lower parts. The inner surface of the limit plate 2 633 is slidably connected with the inner surface of the adjacent sliding groove 635. The two pressing blocks 631 are provided with a through hole 1 636 symmetrically at one end close to each other. The inner surfaces of the two through holes 1 636 on the same side are slidably connected with the limit shaft 632. The two pressing blocks 631 are provided with an arc groove 637 that is closely attached to the adjacent clamping assembly 64 on one side away from the pulley 1 611. The two pressing blocks 631 are provided with a plane that is in contact with the guide plate 53 on one side away from each other. The two guide plates 53 have the same trajectory as the guide groove 51, and the left and right sides of the two guide plates 53 are horn-shaped.

[0059] In order to enable the clamping assembly 64 to clamp the aluminum-plastic plate during the degreasing and spray cleaning process, the clamping assembly 64 is in a relaxed state within the action range of the feed conveyor belt 11 and the discharge conveyor belt 12, and a pressing assembly 63 is provided to cooperate with the guide plate 53 to act on the clamping assembly 64 so that the clamping assembly 64 can clamp the aluminum-plastic plate;

[0060] Specifically, when the second limiting plates 633 on both sides are at the bell mouth formed by the two guide plates 53, that is, within the range of the feed conveyor belt 11 and the discharge conveyor belt 12, they will move away from the outside under the action of the limiting shaft 632, and at this time, the clamping plate 641 is not subjected to force and is in an open state;

[0061] However, when the pressing block 631 gradually enters the track formed by the two guide plates 53, it will be gradually pressed inward by the guide plates 53, the limiting shaft 632 is stressed, and the clamping plate 641 is pressed inward by the arc groove 637;

[0062] Therefore, the aluminum-plastic plate will be gradually clamped in the feeding conveyor belt 11 area so that the clamping plate 641 carries the aluminum-plastic plate into the area where the degreasing agent storage tank 7 is located, and the aluminum-plastic plate will be gradually released in the discharging conveyor belt 12 area so that it falls on the discharging conveyor belt 12 and is taken away by the discharging conveyor belt 12.

[0063] And because there is a partial flat surface on the side where the pressing block 631 contacts the guide plate 53, when the driving assembly 61 rotates, it will not drive the pressing block 631 to rotate, thereby avoiding the aluminum-plastic plate from falling off during the wetting and spraying process. Moreover, its flat surface portion is relatively small, and its smoothness of movement will not be affected during the turning process.

[0064] The annular groove 634 provided at the same time can limit the pressing block 631 without affecting the rotation of the driving assembly 61 .

[0065] Further, to achieve the clamping and loosening of the aluminum-plastic panel, refer to Fig.13 and Fig.14 The clamping assembly 64 includes a through hole three 647 symmetrically opened at the upper and lower front of the outer surface of the narrower part of the convex connecting shaft 62 and a limit rod two 646 slidably connected to the inner surface of the through hole three 647, the ends of the two limit rods two 646 away from each other are fixedly connected to the limit ring 643, the ends of the two limit rings 643 away from the convex connecting shaft 62 are fixedly connected to the clamping plate 641, the ends of the two clamping plates 641 close to each other are linearly distributed and fixedly connected to a plurality of airbag cushions 642, the ends of the two limit rings 643 close to each other are opened with a through hole two 645, the inner surfaces of the two through holes two 645 are slidably connected to the limit rod one 644, and the outer surfaces of the two limit rings 643 are respectively tightly attached to the inner arc surface of the arc groove 637 on the same side.

[0066] When the pressing block 631 is pressed inward, the limiting ring 643 will be driven to move inward along the limiting rod 1 644 and the through hole 3 647, and at this time, the limiting rod 2 646 is compressed and stores energy. When the limiting ring 643 drives the splint 641 inward, the airbag cushion 642 will be pressed against the surface of the aluminum-plastic plate. Since the airbag cushion 642 will have a certain deformation, the contact between the splint 641 and the aluminum-plastic plate can be made closer, thereby ensuring the stability of the clamping and fixation.

[0067] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
