Description

Technical Field

[0001] This utility model belongs to the technical field of spraying devices, specifically relating to a magnetic block processing spraying device with residual material recovery. Background Technology

[0002] The magnetic block processing and spraying device is mainly based on the principles of high-pressure airless spraying, electrostatic spraying, or air spraying. It evenly covers the surface of the magnetic block with protective coating to form a strong protective film. Taking electrostatic spraying as an example, the device uses a high-voltage electrostatic generator to charge the coating. When the magnetic block passes near the spray gun, the charged coating particles are quickly and evenly adsorbed onto the surface of the magnetic block under the action of electrostatic force, achieving efficient and precise spraying operations.

[0003] In the process of coating magnetic blocks, to ensure that the surface of the magnet is completely covered by the coating and to achieve the desired protective and aesthetic effect, operators often use a relatively large amount of paint in a single spraying. This is mainly because magnetic blocks have different shapes, and it is difficult to achieve uniform adhesion to special areas such as corners and grooves. To avoid blind spots in the coating, it is necessary to increase the amount of paint used to ensure complete coverage.

[0004] However, this spraying method leads to significant paint waste. During the spraying process, due to gravity and spraying pressure, a large amount of excess paint drips directly onto the bottom of the placement platform along the surface of the magnetic blocks and the spray gun's trajectory. This scattered paint is extremely difficult to collect, as conventional collection tools struggle to reach into crevices for effective cleaning. The dried paint adheres tightly to the bottom of the placement platform; forcibly scraping it off with scrapers not only damages the platform's surface material but also causes the paint to break into fine particles, further spreading to other parts of the equipment, increasing the cleaning area and hindering subsequent cleaning. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic block processing spraying device with waste material recovery, aiming to solve the problem that during the spraying process, due to gravity and spraying pressure, a large amount of excess paint drips directly onto the bottom of the placement platform along the surface of the magnetic block and the spray gun's trajectory. This spilled paint is extremely difficult to recover, as conventional collection tools struggle to reach into crevices for effective cleaning. The dried paint adheres tightly to the bottom of the placement platform; forcibly scraping it off with scrapers not only easily damages the platform's surface material but also causes the paint to break into fine particles, further spreading to other parts of the equipment, increasing the cleaning area and hindering subsequent cleaning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a magnetic block processing spraying device with waste material recovery, comprising a frame, a sprayer installed inside the frame, a placement platform at the bottom of the sprayer, the outer walls on both sides of the placement platform being installed on the inner wall of the frame, and the bottom of the placement platform being movably connected to the top opening of the receiving hopper.

[0007] The bottom opening of the receiving hopper is closely connected to the outer wall of the top opening of the liquid storage frame. A positioning wheel is movably connected to each side of the liquid storage frame. The upper and lower sides of the positioning wheel are movably connected to the outer wall of a horizontal plate. One side of the two horizontal plates is welded to the outer wall of one side of the fixed plate, and the other side of the fixed plate is welded to the inner wall of the frame.

[0008] In order to enable the liquid storage frame to slide along a fixed trajectory inside the frame, as a magnetic block processing and spraying device with residual material recovery of this utility model, preferably, two guide strips are symmetrically installed on the inner wall of the bottom of the frame cavity, and two limiting blocks are symmetrically installed on the longitudinal inner wall of the guide strips, with the other end of the limiting block abutting against the outer wall of one side of the liquid storage frame.

[0009] The bottom of the liquid storage frame is provided with two sliding grooves that are adapted to the corresponding guide strips. The liquid storage frame is slidably connected to the guide strips through the sliding grooves. Two notches are opened on both sides near the bottom of the liquid storage frame, and a filter screen is embedded in the inner wall of the top opening end of the notch.

[0010] In order to ensure that the liquid storage frame can be fixed in the docking position after docking with the material receiving hopper, as the magnetic block processing and spraying device with residual material recycling of this utility model, preferably, a protrusion is welded to the upper and lower sides of the positioning wheel, the protrusion is movably installed in the strip groove of the horizontal plate, one side of the outer wall of the protrusion is fixedly connected to one end of the connecting rod, and the other end of the connecting rod is fixedly connected to one side of the slider.

[0011] A baffle is welded between the two sliders. One side of the baffle is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to one side of the fixed plate. The slider is slidably installed in the strip groove of the horizontal plate. The maximum stroke of the slider from the end away from the protrusion to the end of the strip groove is greater than the depth of the notch.

[0012] In order to ensure that the excess material on the placement table can fall completely into the collection hopper, as a magnetic block processing and spraying device with excess material recycling of this utility model, preferably, the collection hopper is installed in the cavity of the frame, and the opening size of the top of the collection hopper is larger than the plane size of the placement table.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When in use, the bottom of the liquid storage frame is installed into the cavity of the frame along the two guide strips. When one side of the liquid storage frame is blocked by the limit block, the top of the liquid storage frame is precisely aligned with the bottom opening of the receiving hopper.

[0015] In addition, under the action of the spring, the positioning wheel is reset through the baffle, slider, linkage rod and protrusion. In this way, the protrusion on the outer wall of the positioning wheel will be inserted into the corresponding recess, thereby fixing the liquid storage frame in the current position.

[0016] When the sprayer sprays the ferromagnet placed on the platform, excess paint falls into the collection hopper through the gap on the limit block, and then falls down the slope of the collection hopper into the liquid storage frame to be collected. In this way, the above structure can recycle the excess material during use, which facilitates later cleaning. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-4 The present invention provides the following technical solution: a magnetic block processing spraying device with residual material recovery, including a frame 1, a sprayer 2 installed inside the frame 1, the sprayer 2 being installed inside the frame 1 through a displacement mechanism, and in use completing the horizontal and forward and backward movement trajectory above the placement platform 3 through the displacement mechanism, thereby completing the magnetic spraying operation on the relative area.

[0025] The sprayer 2 is connected to the feeding mechanism on the frame 1. When in use, the magnet is sprayed by the control box on one side of the frame 1 in conjunction with the supply of paint.

[0026] The bottom of the sprayer 2 is provided with a placement platform 3. The outer walls on both sides of the placement platform 3 are installed on the inner wall of the frame 1. The bottom of the placement platform 3 is movably connected to the top opening of the receiving hopper 4.

[0027] The bottom opening of the receiving hopper 4 is closely connected to the outer wall of the top opening of the liquid storage frame 5. The bottom of the receiving hopper 4 is made of deformable rubber material, which will deform during the docking process between the receiving hopper 4 and the liquid storage frame 5. After the receiving hopper 4 and the liquid storage frame 5 are docked, an effective sealing structure can be formed between the receiving hopper 4 and the liquid storage frame 5 to prevent residual material from leaking from the connection end between the receiving hopper 4 and the liquid storage frame 5.

[0028] A positioning wheel 6 is movably connected to each side of the liquid storage frame 5. The upper and lower sides of the positioning wheel 6 are movably connected to the outer wall of a horizontal plate 7. One side of the two horizontal plates 7 is welded to the outer wall of one side of the fixed plate 8, and the other side of the fixed plate 8 is welded to the inner wall of the frame 1.

[0029] Preferably, two guide bars 11 are symmetrically installed on the inner wall of the bottom of the cavity of the frame 1, and two limiting blocks 12 are symmetrically installed on the longitudinal inner wall of the guide bars 11. The other end of the limiting block 12 abuts against the outer wall of one side of the liquid storage frame 5.

[0030] The bottom of the liquid storage frame 5 is provided with two sliding grooves that are adapted to the corresponding guide bars 11. The liquid storage frame 5 is slidably connected to the guide bars 11 through the sliding grooves. Two recesses 51 are opened on both sides near the bottom of the liquid storage frame 5. A filter screen 52 is embedded in the inner wall of the top opening end of the recess 51.

[0031] In practical use, when a larger foreign object falls through the gap on the placement platform 3, the foreign object will fall onto the filter screen 52 along the trajectory of the receiving hopper 4. This can prevent the foreign object from mixing into the remaining material in the liquid storage frame 5.

[0032] Preferably, a protrusion 61 is welded to the upper and lower sides of the positioning wheel 6, and the protrusion 61 is movably installed in the strip groove of the horizontal plate 7. One side of the outer wall of the protrusion 61 is fixedly connected to one end of the connecting rod 62, and the other end of the connecting rod 62 is fixedly connected to one side of the slider 63.

[0033] A baffle 64 is welded between the two sliders 63. One side of the baffle 64 is fixedly connected to one end of the spring 65, and the other end of the spring 65 is fixedly connected to one side of the fixing plate 8. The sliders 63 are slidably installed in the strip groove of the horizontal plate 7. The maximum stroke of the slider 63 from the end away from the protrusion 61 to the end of the strip groove is greater than the depth of the notch 51.

[0034] In practical use, when the spring 65 returns to its original position, it will push the baffle 64 to move. When the baffle 64 moves, it will drive the sliders 63 on both sides to move in the strip groove of the horizontal plate 7. When the sliders 63 move, they will drive the protrusion 61 to move through the linkage rod 62. After the protrusion 61 moves, it will drive the positioning wheel 6 to return to its original position. In this way, the protrusion on the positioning wheel 6 will be inserted into the notch 51, thereby completing the positioning operation of the liquid storage frame 5.

[0035] Preferably, the receiving hopper 4 is installed in the cavity of the frame 1, and the top opening size of the receiving hopper 4 is larger than the plane size of the placement table 3.

[0036] In practical use, the receiving hopper 4 can collect the excess material falling from the placement platform 3 to the greatest extent possible.

[0037] First, precisely align the bottom of the liquid storage frame 5 with the two guide bars 11 inside the frame 1, and push it into the cavity of the frame 1 along the guide bars 11. The guide bars 11 provide precise guidance, ensuring that the liquid storage frame 5 will not shift or tilt during installation. When the liquid storage frame 5 is pushed to one side and is obstructed by the limiting block 12, this obstruction point is the mark of proper installation. At this point, the top of the liquid storage frame 5 and the bottom opening of the receiving hopper 4 are precisely aligned, and the two fit together seamlessly.

[0038] Simultaneously, under the powerful elastic potential energy of spring 65, the baffle 64, slider 63, connecting rod 62, and protrusion 61 are sequentially driven to move in tandem. After being pushed, baffle 64 causes slider 63 to slide within its corresponding track. The sliding of slider 63 then transmits power to protrusion 61 via connecting rod 62, ultimately causing protrusion 61 to reset the positioning wheel 6. After reset, the protrusion on the outer wall of positioning wheel 6 precisely engages with the corresponding recess 51 on liquid storage frame 5, forming a stable snap-fit ​​structure. This design not only prevents displacement of liquid storage frame 5 during equipment operation but also withstands certain external impacts, ensuring that liquid storage frame 5 always remains in the correct working position.

[0039] When the sprayer 2 sprays the ferromagnet placed on the placement platform 3, excess paint is inevitably produced. Under the influence of gravity, this excess paint flows downwards along the gaps in the placement platform 3. After falling into the collection hopper 4, the excess paint slides quickly down the slope and finally falls into the liquid storage frame 5 for collection, thus facilitating later cleaning.

[0040] 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.
