Description

Technical Field

[0001] This utility model relates to the field of powder processing technology, and in particular to a machine for removing impurities from transparent thermosetting powder coatings. Background Technology

[0002] Transparent thermosetting powder coatings are environmentally friendly coating materials that use thermosetting resins as a matrix and are cured at high temperatures to form a three-dimensional cross-linked network structure. However, in the production process of transparent thermosetting powder coatings, metal debris, fiber impurities, and undispersed agglomerated particles or electrostatically adsorbed contaminants are inevitably introduced. The presence of these impurities can lead to defects in the coating such as particle protrusion, reduced transparency, uneven gloss, or even localized breakdown, which seriously affect the appearance quality and mechanical properties of the product. Therefore, impurity removal machines are required.

[0003] Traditional impurity removal methods mainly rely on airflow sorting (utilizing particle density differences), electrostatic dust removal (through charge adsorption), or vibrating sieving (physical sieve interception). Vibrating sieving consists of an impurity removal barrel, filter plates, and a vibrator: First, the filter plates are installed inside the impurity removal barrel. Then, the vibrator drives the filter plates to vibrate. Next, the powder to be removed is poured into the barrel through the top. Under the action of gravity, the powder passes through the vibrating filter plates, causing the electrostatically adsorbed agglomerated particles to disperse into a monodisperse state, reducing the risk of sieve clogging, while the impurities are isolated, thereby achieving the effect of impurity removal.

[0004] However, existing filter plates, when vibrated, have poor dispersion effect on agglomerated particles due to the single vibration force, and cannot achieve dispersion effect on some stubborn particles, thus affecting the overall filtration effect. Therefore, this application proposes a transparent thermosetting powder coating impurity removal machine. Utility Model Content

[0005] The purpose of this invention is to address the problem of poor dispersion in the prior art by proposing a transparent thermosetting powder coating impurity removal machine.

[0006] The technical solution of this utility model: A transparent thermosetting powder coating impurity removal machine, comprising an impurity removal barrel, wherein a filter plate is disposed inside the impurity removal barrel, and further comprising:

[0007] The device box is symmetrically distributed on both sides of the impurity removal barrel. A limiting rod is fixed inside the device box and passes through the first filter plate. A second filter plate is arranged inside the impurity removal barrel and above the first filter plate. A connecting ring is fixed to the top of the second filter plate and is rotatably connected to the inner wall of the impurity removal barrel. A driving mechanism is arranged on the outside of the impurity removal barrel for moving the first filter plate.

[0008] Optionally, the drive mechanism includes a motor, an impact rod, and a connecting rod. The motor is mounted on the outside of the impurity removal barrel, the impact rod is driven to the outside of the motor's output end, and the connecting rod is fixed to the outside of the filter plate.

[0009] Optionally, a spring is sleeved on the outer side of the limiting rod, and the two ends of the spring are respectively fixedly connected to the device box and the filter plate.

[0010] Optionally, the second filter plate is provided with a rotating mechanism that cooperates with the first filter plate. The rotating mechanism is used to drive the second filter plate to rotate when the first filter plate is raised or lowered.

[0011] Optionally, the rotating mechanism includes a screw and a slider. The screw is fixed to the top of the first filter plate, and the slider is fixed inside the second filter plate. The slider is threadedly connected to the outer side of the screw.

[0012] Optionally, the device box has a sliding groove inside, and an isolation plate is slidably connected inside the sliding groove. The isolation plate is fixed to the outside of the connecting rod.

[0013] Optionally, a roller is provided on the outer side of the striking rod, and the roller is rotatably connected to the end of the connecting rod away from the device box.

[0014] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. This device achieves efficient impurity removal through the cooperation of filter plate one and filter plate two drive mechanisms. The drive mechanism moves the rigid filter plate one up and down, pushing the powder to contact the flexible filter plate two, where the agglomerated particles are crushed by compression and shearing. The vibration of the filter plate when it falls and the elastic deformation of the flexible plate generate vibration energy, preventing the powder from agglomerating again. The flexible filter plate two adaptively adjusts the gap to enhance vibration transmission and avoid clogging. The mechanical linkage design replaces traditional screening, effectively improving the impurity removal effect and continuous working capability.

[0016] 2. Through the structural design of the rotating mechanism, this device enables the second filter plate to rotate as the first filter plate moves up and down. This utilizes centrifugal force to disperse the powder and prevent its accumulation. At the same time, the squeezing and shearing forces and the rotational tangential forces in the contact area of ​​the two plates work together to break up hard lumps, achieving uniform powder dispersion and efficient dissociation, and significantly improving the impurity removal and anti-clogging effect.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] like Figures 1-3 As shown, this utility model proposes a transparent thermosetting powder coating impurity removal machine, including an impurity removal barrel 1. A filter plate 2 is installed inside the impurity removal barrel 1. Powder to be removed is fed into the impurity removal barrel 1 through its top. Under the action of gravity, the powder passes through the filter plate 2, and the impurities inside are isolated. The machine also includes: a device box 3 symmetrically distributed on both sides of the impurity removal barrel 1; a limiting rod 4 fixedly connected inside the device box 3, the limiting rod 4 penetrating the filter plate 2; a filter plate 5 installed inside the impurity removal barrel 1 and above the filter plate 2; the diameter of the small holes inside the filter plate 5 is larger than the diameter of the small holes inside the filter plate 2 to facilitate powder passage; and the filter plate 5 can also perform preliminary filtration and impurity removal on the powder. A connecting ring 6 is fixedly connected to the top of the filter plate 5, and the connecting ring 6 is rotatably connected to the inner wall of the impurity removal barrel 1, providing support for the filter plate 5.

[0026] Among them, such as Figure 3As shown, a driving mechanism is provided on the outside of the impurity removal barrel 1. The driving mechanism is used to move the filter plate 2. The driving mechanism will first drive the filter plate 2 to rise. The powder that has not yet fallen off the top of the filter plate 2 will rise synchronously with the filter plate 2. The rising powder will contact the filter plate 5 and be squeezed by the filter plate 2 and the filter plate 5, thereby breaking up the agglomerated powder particles and making them loose. It should be noted that there will still be a certain gap between the filter plate 2 and the filter plate 5 at the limit distance of the rise. The filter plate 5 is made of flexible material and can deform appropriately. When the filter plate 2 rises to the limit distance, the driving mechanism ends the control of the filter plate 2. The filter plate 2 will fall naturally under the action of gravity. The upward movement of the filter plate 2 and the contact of the powder with the filter plate 5 will generate an upward vibration force. When the filter plate 2 falls to the bottom, it will generate a downward vibration force with the inner wall of the device box 3. The vibration force generated by both can achieve the function of dispersing the powder and preventing clogging.

[0027] In addition, such as Figure 2 and Figure 3 As shown, the drive mechanism includes a motor 7, an impact rod 8, and a connecting rod 9. The drive mechanism is described in detail below:

[0028] The motor 7 is installed on the outside of the impurity removal barrel 1, and the impact rod 8 is connected to the outside of the output end of the motor 7. When the motor 7 is running, it will drive the impact rod 8 to... Figure 3 With the viewing angle rotating clockwise, the connecting rod 9 is fixed to the outside of the filter plate 2. When the impact rod 8 rotates, it will contact the connecting rod 9. At this time, the connecting rod 9 is subjected to the squeezing force of the impact rod 8, which will drive the filter plate 2 to move upward. As the impact rod 8 rotates, the impact rod 8 will stop squeezing the connecting rod 9, and the filter plate 2 and the connecting rod 9 will fall under the action of gravity. Then, the impact rod 8 will squeeze the connecting rod 9 again, thus repeating the above action.

[0029] Furthermore, such as Figure 3 As shown, a spring 10 is sleeved on the outer side of the limiting rod 4. The two ends of the spring 10 are fixed to the device box 3 and the filter plate 2 respectively. When the filter plate 2 moves upward, it will cooperate with the device box 3 to squeeze the spring 10, causing the spring 10 to deform under force and generate elastic potential energy. When the filter plate 2 stops squeezing the spring 10, the spring 10 will release the elastic potential energy, thereby pushing the filter plate 2 to move downward quickly, avoiding the filter plate 2 falling slowly by gravity and the situation of jamming.

[0030] In addition, such as Figure 3 and Figure 4As shown, the filter plate 25 has a rotating mechanism inside that cooperates with the filter plate 12. The rotating mechanism drives the filter plate 25 to rotate when the filter plate 12 is raised or lowered. When the filter plate 12 moves up or down, it will cooperate with the filter plate 25 to drive the rotating mechanism. The rotating mechanism will drive the filter plate 25 to rotate as the filter plate 12 moves. When the filter plate 25 rotates, it can generate centrifugal force on the powder on the surface, making the powder more evenly dispersed and avoiding the accumulation in one place. At the same time, in the compression zone formed by the dynamic meshing area of ​​the filter plate 12 and the filter plate 25, the powder is subjected to bidirectional shear force. This includes the pressure on the filter plate 12 and the tangential friction force generated by the rotation of the filter plate 25 to break up agglomerates. It also enhances the collision energy between particles through centrifugal acceleration, thereby achieving ultra-fine disintegration of hard agglomerates. This design completes the dual functions of dispersion and breakup simultaneously through the motion coupling mechanism, ensuring that the powder maintains a uniform fluidized distribution during the dynamic process.

[0031] Among them, such as Figure 4 As shown, the rotating mechanism includes a screw 11 and a slider. The rotating mechanism is described in detail below:

[0032] The screw 11 is fixed to the top of the filter plate 2, and the slider is fixed inside the filter plate 5. The slider is threadedly connected to the outer side of the screw 11. When the filter plate 2 rises and falls, it will drive the screw 11 to move synchronously. Since the screw 11 is fixed to the filter plate 2, the slider will rotate in order to match the movement trajectory of the outer thread of the screw 11. The rotation of the slider will then drive the filter plate 5 to achieve the purpose of rotation.

[0033] Furthermore, such as Figure 3 and Figure 5 As shown, the device box 3 has a sliding groove 12 inside, and an isolation plate 13 is slidably connected inside the sliding groove 12. The opening of the sliding groove 12 can provide the isolation plate 13 with a moving space. The isolation plate 13 is fixed to the outside of the connecting rod 9. When the connecting rod 9 moves up and down, the powder may leave the inside of the impurity removal barrel 1 from the space where the connecting rod 9 moves before it has been filtered. The isolation plate 13 can fill the gap between the connecting rod 9 and the device box 3. When the connecting rod 9 moves, it will drive the isolation plate 13 to move, thereby blocking the powder.

[0034] In addition, such as Figure 5 As shown, a roller 14 is provided on the outer side of the striking rod 8. The roller 14 is rotatably connected to the end of the connecting rod 9 away from the device box 3. The rotation of the roller 14 can reduce the friction force of the striking rod 8 directly contacting the connecting rod 9, thereby improving the service life of the device.

[0035] In this embodiment, the powder to be removed is fed into the removal tank 1 through its top. Under the action of gravity, the powder passes through the filter plate 2, while the impurities inside are isolated. When the motor 7 runs, it drives the impact rod 8 to rotate. When the impact rod 8 rotates, it contacts the connecting rod 9. The connecting rod 9 is then subjected to the squeezing force of the impact rod 8, which causes the filter plate 2 to move upward. The powder that has accumulated at the top of the filter plate 2 and has not yet fallen off will rise synchronously with the rise of the filter plate 2. As the powder rises, it will contact the filter plate 5 and be squeezed by both the filter plate 2 and the filter plate 5. This breaks down the agglomerated powder particles, making them loose. As the impact rod 8 rotates, it stops pressing on the connecting rod 9, and the filter plate 2 and the connecting rod 9 fall under the influence of gravity. Then, the impact rod 8 presses on the connecting rod 9 again, thus repeating the above action. When the filter plate 2 moves upward, it cooperates with the device box 3 to compress the spring 10, causing the spring 10 to deform under force and generate elastic potential energy. When the filter plate 2 stops pressing on the spring 10, the spring 10 releases its elastic potential energy, thereby pushing the filter plate 2 to move downward quickly.

[0036] When filter plate 12 rises and falls, it will drive screw 11 to move synchronously. Since screw 11 is fixed to filter plate 12, the slider will rotate in order to match the movement trajectory of the outer thread of screw 11. The rotation of the slider will then drive filter plate 25 to rotate.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
