Description

Technical Field

[0001] This utility model relates to the field of raw material screening technology, specifically a separation and screening device for the production of fluorocarbon powder coatings. Background Technology

[0002] In modern industrial production, fluorocarbon powder coatings are widely used in construction, home appliances, automobiles, and other fields due to their excellent weather resistance, corrosion resistance, wear resistance, and good decorative properties. As market demands for the quality of fluorocarbon powder coatings continue to rise, the screening and processing of raw materials and finished products during production becomes particularly crucial.

[0003] Most commercially available fluorocarbon powder coating separation and sieving devices use a single sieving structure. This coating sieving method makes it difficult to separate impurities of different particle sizes, resulting in low sieving accuracy and failing to meet high-standard production requirements. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a separation and sieving device for the production of fluorocarbon powder coatings, which solves the problem of difficulty in separating impurities of different particle sizes, resulting in low sieving accuracy.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a separation and sieving device for fluorocarbon powder coating production, comprising a tank, an inlet fixedly connected to the top of the tank, an outlet fixedly connected to the bottom of the tank, a drive motor fixedly connected to the outer wall of the tank, an observation window provided on the outer wall of the tank, and a sieving component and a cleaning component fixedly connected to the inner wall of the tank; the sieving component includes a first rotating shaft, a striking block fixedly connected to the outer wall of the first rotating shaft, a first fixing block fixedly connected to the inner wall of the tank, a first pulley fixedly connected to the output end of the drive motor, the outer wall of the first pulley being connected to the outer wall of a second pulley via a transmission belt, a second rotating shaft fixedly connected to the outer wall of the second pulley, and a second fixing block rotatably connected to the outer wall of the second rotating shaft.

[0008] Preferably, a first spring is fixedly connected to the bottom of the first fixing block. The first fixing block is fixedly connected to the first screen through the first spring, and the bottom of the first spring is fixedly connected to the outer wall of the first screen. The outer wall of the first fixing block is fixedly connected to the inner wall of the tank. The outer wall of the first screen is slidably connected to the inner wall of the tank. The outer wall of the striking block is in contact with the bottom of the first screen. The first fixing block restricts the position of the second spring. When the striking block is in contact with the first screen, it will squeeze it, causing the first screen to move upward. When the striking block is not in contact with the first screen, the first spring will reset the first screen through its own elasticity, causing the first screen to reciprocate to perform preliminary screening of the powder on its surface.

[0009] Preferably, the outer wall of the second pulley is rotatably connected to a cam via a second rotating shaft, and the end of the second rotating shaft is fixedly connected to the outer wall of the cam. The inner wall of the cam is rotatably connected to a connecting rod, and the outer wall of the connecting rod is fixedly connected to a second screen. The outer wall of the second fixing block is fixedly connected to the outer wall of the tank. The second screen is slidably connected to the inner wall of the tank via a groove, and the groove is formed in the wall of the tank. The second fixing block restricts the position of the second rotating shaft. The second screen reciprocates and slides due to the pulling of the cam and the connecting rod, thus performing secondary screening of the powder.

[0010] Preferably, the cleaning assembly includes a push-pull plate, a handle is fixedly connected to the outer wall of the push-pull plate, a second spring is sleeved on the outer wall of the handle, a connecting plate is slidably connected to the outer wall of the handle, and a plug is fixedly connected to the inner wall of the connecting plate.

[0011] Preferably, the push-pull plate is slidably connected to the tank body via a groove, and the groove is formed in the wall of the tank body, allowing the push-pull plate to slide along the groove formed in the inner wall of the tank body.

[0012] Preferably, one end of the second spring is fixedly connected to the outer wall of the push-pull plate, and the other end of the second spring is fixedly connected to the outer wall of the connecting plate. The insertion rod is inserted into the tank through a slot, and the slot is opened in the wall of the tank. Pulling the connecting plate moves the insertion rod with the connecting plate without inserting it into the tank. Pulling the handle can drive the push-pull plate to move, which can clean the impurities remaining on the outer wall of the first screen.

[0013] (III) Beneficial Effects

[0014] This invention provides a separation and sieving device for the production of fluorocarbon powder coatings. It has the following beneficial effects:

[0015] (I) The separation and sieving device for fluorocarbon powder coating production has a first screen that reciprocates under the synergistic action of a striking block, a first fixed block, and a first spring, which can perform preliminary screening of powder and separate larger particle impurities in a timely manner. The second screen, with the help of a convex disc, a connecting rod, and a second rotating shaft, forms a reciprocating sliding motion to achieve secondary screening and further separate fine impurities. This two-stage screening structure improves the separation efficiency and quality of powder compared to a single screening method, ensuring that the produced fluorocarbon powder coating has uniform particle size and low impurity content, meeting the requirements of high-standard production.

[0016] (II) The separation and screening device for fluorocarbon powder coating production can clean the impurities remaining on the outer wall of the first screen by pulling the connecting plate to disengage the insert rod from the slot and then pulling the handle to drive the push-pull plate to slide in the chute. This automatic cleaning structure avoids the tedious operation of frequent manual disassembly and cleaning, which not only saves time and labor costs, but also prevents the screen from being blocked due to the accumulation of impurities, ensuring the continuous screening work and extending the service life of the equipment.

[0024] 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.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a separation and sieving device for fluorocarbon powder coating production, comprising a tank 1, an inlet 2 fixedly connected to the top of the tank 1, an outlet 3 fixedly connected to the bottom of the tank 1, a drive motor 4 fixedly connected to the outer wall of the tank 1, an observation window 5 opened on the outer wall of the tank 1, and a sieving component 6 and a cleaning component 7 fixedly connected to the inner wall of the tank 1; the sieving component 6 includes a first rotating shaft 61, a striking block 62 fixedly connected to the outer wall of the first rotating shaft 61, a first fixing block 63 fixedly connected to the inner wall of the tank 1, and the drive motor 4... A first pulley 66 is fixedly connected to the outlet end. The outer wall of the first pulley 66 is connected to the outer wall of the second pulley 67 via a transmission belt. A second rotating shaft 69 is fixedly connected to the outer wall of the second pulley 67. A second fixing block 68 is rotatably connected to the outer wall of the second rotating shaft 69. A first spring 64 is fixedly connected to the bottom of the first fixing block 63. The first fixing block 63 is fixedly connected to the first screen 65 via the first spring 64, and the bottom of the first spring 64 is fixedly connected to the outer wall of the first screen 65. The outer wall of the first fixing block 63 is fixedly connected to the inner wall of the tank 1. The outer wall of the first screen 65 is slidably connected to the inner wall of the tank 1. The outer wall of the striking block 62 is in contact with the bottom of the first screen 65. The first fixing block 63 restricts the position of the second spring. When the striking block 62 is in contact with the first screen 65, it will squeeze it, causing the first screen 65 to move upward. When the striking block 62 is not in contact with the first screen 65, the first spring 64 will reset the first screen 65 through its own elastic force, causing the first screen 65 to reciprocate to perform preliminary screening of the powder on its surface. The outer wall of the second pulley 67 is rotatably connected to the cam 6 via the second rotating shaft 69. 10. The end of the second rotating shaft 69 is fixedly connected to the outer wall of the cam 610. The inner wall of the cam 610 rotates to connect the connecting rod 611. The outer wall of the connecting rod 611 is fixedly connected to the second screen 612. The outer wall of the second fixing block 68 is fixedly connected to the outer wall of the tank 1. The second screen 612 is slidably connected to the inner wall of the tank 1 through a groove. The groove is opened in the wall of the tank 1. The second fixing block 68 restricts the position of the second rotating shaft 69. The second screen 612 is pulled by the cam 610 and the connecting rod to form a reciprocating sliding motion, and performs secondary screening of the powder.

[0026] The cleaning component 7 includes a push-pull plate 71, a handle 72 fixedly connected to the outer wall of the push-pull plate 71, a second spring 73 sleeved on the outer wall of the handle 72, a connecting plate 74 slidably connected to the outer wall of the handle 72, and a rod 75 fixedly connected to the inner wall of the connecting plate 74. The push-pull plate 71 is slidably connected to the tank 1 through a groove, and the groove is opened in the wall of the tank 1. The push-pull plate 71 slides in the groove opened in the inner wall of the tank 1. One end of the second spring 73 is fixedly connected to the outer wall of the push-pull plate 71, and the other end of the second spring 73 is fixedly connected to the outer wall of the connecting plate 74. The rod 75 is inserted into the tank 1 through a slot, and the slot is opened in the wall of the tank 1. Pulling the connecting plate 74 moves the rod 75 with the connecting plate 74 without inserting it into the tank 1. Pulling the handle 72 can move the push-pull plate 71, which can clean the impurities remaining on the outer wall of the first screen 65.

[0027] In use, when sieving powder coating is required, the motor is started, and the motor drives the first rotating shaft 61 to rotate. The first rotating shaft 61 drives the striking block 62 on the outer wall to move. When the striking block 62 rotates to contact the bottom of the first screen 65, it will exert an upward squeezing force on the first screen 65. At this time, since the first fixing block 63 is fixed to the inner wall of the tank 1, it restricts the position of the first spring 64. Under the squeezing of the striking block 62, the first screen 65 overcomes the elastic force of the first spring 64 and moves upward. When the striking block 62 continues to rotate and no longer contacts the first screen 65, the first spring 64 pulls the first screen 65 back to its original position by its own elastic force. This cycle continues. Then, the first screen 65 vibrates continuously up and down under the action of the striking block 62, causing the fluorocarbon powder coating falling on the first screen 65 to fall through the screen holes during the vibration, while larger particles of impurities or insufficiently dispersed powder clumps remain on the first screen 65, completing the initial screening. When the second belt pulley 67 rotates, it drives the second rotating shaft 69 fixedly connected to it to rotate. During the rotation of the second rotating shaft 69, the cam 610 fixedly connected to the end of the second rotating shaft 69 rotates together with the second rotating shaft 69. During the rotation of the cam 610, the second screen 612 is pulled through the connecting rod 611. When the cam 610 rotates, the second screen 612 is pulled through the connecting rod 611. When the first screen 612 rotates to a specific position, it pulls the connecting rod 611, which in turn causes the second screen 612 to slide back and forth within the groove in the wall of the tank 1. During this back-and-forth sliding process, the second screen 612 performs a secondary screening of the powder that has passed through the first screen 65, further separating out finer impurities or powder particles that do not meet the particle size requirements. This ensures that the fluorocarbon powder coating passing through the second screen 612 meets the required particle size standard. Finally, the qualified powder is discharged from the outlet 3 at the bottom of the tank 1. After the first screen 65 has completed multiple screening operations, some larger particles of impurities or powder clumps may remain on its surface. At this time, the cleaning component 7 is required for cleaning. Pull the connecting plate 74. Since one end of the second spring 73 is fixedly connected to the push-pull plate 71 and the other end is fixedly connected to the connecting plate 74, the insertion rod 75 moves with the connecting plate 74 during the pulling process, so that the insertion rod 75 is no longer inserted into the slot opened in the wall of the tank 1. At this time, pull the handle 72 again, and the push-pull plate 71 can slide in the groove opened in the wall of the tank 1. During the sliding process, the push-pull plate 71 can scrape off the impurities remaining on the outer wall of the first screen 65. After cleaning, release the connecting plate 74. Under the elastic force of the second spring 73, the insertion rod 75 is reinserted into the slot to fix the push-pull plate 71 for the next cleaning operation.
