Description

Technical Field

[0001] This utility model relates to the field of paint drying technology, specifically to a raw material drying device for paint production. Background Technology

[0002] Paint is a chemical mixture that can firmly cover the surface of an object, serving as a protective, decorative, marking, and other special-purpose coating. The authoritative book in the coatings industry, "Coating Technology," defines it as follows: "Coating is a material that can be applied to the surface of an object using different construction techniques to form a firmly adhered, continuous solid film with a certain strength. In the production of paint, most of the raw materials are mineral raw materials, which need to be dried."

[0003] In response, Chinese patent application number CN209840651U discloses a drying device for paint raw materials. Addressing the issue of limited functionality in existing drying systems, the following solution is proposed: a drying mechanism and a dehydration mechanism. The dehydration mechanism includes a dehydration tank. A first partition plate arranged along the diameter direction is installed at the bottom of the dehydration tank. A disc is welded to the top of the first partition plate. A rotating shaft is installed at the center of the top of the disc. A rotating block is fixedly sleeved on the outer ring of the rotating shaft and slidably sleeved with the inner wall of the dehydration tank. The top of the rotating block has receiving grooves arranged in an array along its axis, and the bottom of the receiving grooves has a discharge channel arranged along the diameter direction of the rotating block. This invention replaces the wetter desiccant, thereby improving the drying of humid and hot airflow, enabling continuous operation, and reducing energy loss and increasing efficiency by drying the moisture in the humid and hot airflow before reuse.

[0004] However, in actual use, the raw materials can only be placed on the surface of the conveyor for drying, and the lower end of the raw materials will contact the surface of the conveyor. As a result, the drying effect of the lower end of the raw materials is poor, and the raw materials cannot be dried quickly and evenly. At the same time, there is no storage function when unloading. Therefore, improving and perfecting the above problems has become an urgent issue to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a raw material drying device for paint production, in order to solve the problems mentioned in the background art, where raw materials can only be placed on the surface of the conveyor for drying, and the lower end of the raw material will contact the surface of the conveyor, resulting in poor drying effect at the lower end of the raw material, and the inability to dry the raw material quickly and evenly. At the same time, it does not have a collection function when unloading.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material drying device for paint production, comprising a base plate, a support plate mounted on the top surface of the base plate, a drying cylinder mounted on the upper surface of the support plate, a feed pipe provided on the top surface of the drying cylinder, a motor housing mounted on the right side surface of the drying cylinder, a servo motor disposed inside the motor housing, a rotating shaft mounted through the output end of the servo motor on the right side surface of the drying cylinder, a rotating cylinder mounted on the outer surface of the rotating shaft, and a first placement plate mounted on both the upper and lower surfaces of the rotating cylinder, with a mesh body disposed inside the first placement plate.

[0007] Preferably, a second placement plate is installed on both the front and rear surfaces of the rotating cylinder, and the second placement plate has the same structure as the first placement plate.

[0008] Preferably, a limiting ring is provided on the right side surface of the first and second placement plates, and the limiting ring is adapted to the drying cylinder.

[0009] Preferably, the inner bottom wall of the drying cylinder is provided with a feeding groove, and a blocking plate is installed inside the feeding groove.

[0010] Preferably, a telescopic rod is installed at the lower end of the blocking plate, and a storage box is installed at the lower end of the telescopic rod. The storage box is installed on the upper surface of the base plate, and the material discharge trough and the blocking plate are mutually compatible.

[0011] Preferably, an air supply head is installed inside the drying cylinder, an air supply frame is installed on the front surface of the air supply head, a conveying pipe is installed on the front surface of the air supply frame, a hot air fan is installed at the front end of the conveying pipe, a fixing frame is installed on the lower surface of the hot air fan, and the fixing frame is installed on the top surface of the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This paint production raw material drying device, through the setting of a support plate, drying cylinder, feed pipe, rotating shaft, rotating cylinder, first placement plate, mesh body, second placement plate, limiting ring, and feeding chute, firstly feeds paint raw material into the feed pipe during drying, and then the raw material falls into the drying cylinder, where it falls between the first and second placement plates. Each of the first and second placement plates has four sets of placement areas, thus providing four places for raw material placement. Then, a servo motor is started, driving the rotating shaft to rotate, which in turn drives the rotating cylinder to rotate. The raw material placed on the surfaces of the first and second placement plates rotates with the rotating cylinder, thus increasing the contact area between the raw material and the hot air inside the drying cylinder. This allows for efficient rotational drying of the raw material, changing its position and extending the contact time between the outer surface of the raw material and the hot air. Simultaneously, the limiting ring design limits the position of the raw material, preventing it from falling during rotation, demonstrating the practicality of the design.

[0014] 2. This raw material drying device for paint production, consisting of a storage box, telescopic rod, blocking plate, air supply frame, air supply head, conveying pipe, hot air fan, and fixed frame, allows for material unloading after the drying process. The raw material is piled between the first and second placement plates on the lower surface of the drying cylinder. The telescopic rod is then activated, causing the blocking plate to move downwards, opening the previously sealed unloading trough. The raw material, under gravity, falls from the trough into the storage box for collection. The rotating cylinder continues to rotate, and the first and second placement plates guide the remaining raw material into the unloading trough, providing a guiding effect for rapid unloading. The storage box collects the dried raw material. The hot air fan delivers hot air through the conveying pipe, which is then conveyed to the drying cylinder via the air supply frame and air supply head. This high internal temperature within the drying cylinder allows the raw material to dry, demonstrating the device's functionality. Attached Figure Description

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.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] A raw material drying device for paint production is disclosed in this application. The drying cylinder 3, the mesh body 9, the telescopic rod 14, the air supply frame 16, the air supply head 17, and the hot air blower 19 used in this application are all commercially available products. Their principles and connection methods are well-known prior art and will not be described in detail here. The device includes a base plate 1, a support plate 2 mounted on the top surface of the base plate 1, a drying cylinder 3 mounted on the upper surface of the support plate 2, a feed pipe 4 on the top surface of the drying cylinder 3, a motor housing mounted on the right side surface of the drying cylinder 3, a servo motor housed inside the motor housing, a rotating shaft 6 mounted through the output end of the servo motor on the right side surface of the drying cylinder 3, a rotating cylinder 7 mounted on the outer surface of the rotating shaft 6, and first placement plates mounted on both the upper and lower surfaces of the rotating cylinder 7. 8. The first placement plate 8 has a mesh body 9 inside. The front and rear surfaces of the rotating cylinder 7 are both equipped with second placement plates 10. The second placement plates 10 have the same structure as the first placement plate 8. The right side surfaces of the first placement plate 8 and the second placement plate 10 are provided with limit rings 11. The limit rings 11 are adapted to the drying cylinder 3. The inner bottom wall of the drying cylinder 3 is provided with a feeding groove 12. The feeding groove 12 is equipped with a blocking plate 15. The lower end of the blocking plate 15 is equipped with a telescopic rod 14. The lower end of the telescopic rod 14 is equipped with a storage box 13. The storage box 13 is installed on the upper surface of the bottom plate 1. The feeding groove 12 and the blocking plate 15 are adapted to each other. The drying cylinder 3 is equipped with an air supply head 17. The front surface of the air supply head 17 is equipped with an air supply frame 16. The front surface of the air supply frame 16 is... A conveying pipe 18 is installed on the surface of the base plate 1, and a hot air blower 19 is installed at the front end of the conveying pipe 18. A fixing frame 20 is installed on the lower surface of the hot air blower 19 and is installed on the top surface of the base plate 1. During drying, paint raw materials are first fed into the feed pipe 4, and then the raw materials fall into the drying cylinder 3. At this time, the raw materials fall between the first placement plate 8 and the second placement plate 10, and each of the first placement plate 8 and the second placement plate 10 is provided with four sets, so there are four places to place raw materials between the first placement plate 8 and the second placement plate 10. Then, the servo motor is started, and the servo motor drives the rotating shaft 6 to rotate. Then, the rotating shaft 6 drives the rotating cylinder 7 to rotate. At this time, the raw materials placed on the surface of the first placement plate 8 and the second placement plate 10 will... As the rotating drum 7 rotates, the raw material has extensive contact with the hot air inside the drying drum 3, allowing for comprehensive rotational drying. The design of the limiting ring 11 keeps the raw material in place, preventing it from falling during rotation. During drying, paint raw material is first fed into the feed pipe 4, then falls into the drying drum 3, landing between the first placement plate 8 and the second placement plate 10. Each placement plate 8 and 10 has four sets of placement areas, providing four places to hold the raw material. The servo motor is then activated.A servo motor drives the rotating shaft 6 to rotate, which in turn drives the rotating cylinder 7 to rotate. The raw materials placed on the first placement plate 8 and the second placement plate 10 rotate along with the rotating cylinder 7, allowing for greater contact between the raw materials and the hot air inside the drying cylinder 3. This overall rotational drying process changes the position of the raw materials, extending the contact time between their outer surfaces and the hot air. Simultaneously, the limiting ring 11 restricts the position of the raw materials, preventing them from falling during rotation. The mesh body 9 is mesh-like, and its aperture is smaller than that of the raw materials, preventing them from getting stuck inside. The mesh body 9 also allows for the circulation of hot air inside the drying cylinder 3.

[0023] Working Principle: When using this device, the operator first connects it to an external power source to provide electrical support. During drying, paint raw materials are first fed into the feed pipe 4, then fall into the drying cylinder 3, landing between the first placement plate 8 and the second placement plate 10. Each placement plate 8 and 10 has four sets of placement areas, providing four places to place the raw materials. The servo motor is then activated, driving the rotating shaft 6 to rotate, which in turn drives the rotating cylinder 7. The raw materials placed on the surfaces of the first and second placement plates 8 and 10 rotate with the cylinder 7, increasing their contact with the hot air inside the drying cylinder 3. This rotational drying process allows the raw materials to be dried more thoroughly. The device can change the position of the raw materials, extending the contact time between the outer surface and the hot air. Simultaneously, the limiting ring 11 restricts the position of the raw materials. After the drying process is completed, when it is time to unload the material, the material between the first placement plate 8 and the second placement plate 10 is piled on the lower surface of the drying cylinder 3. At this time, the telescopic rod 14 is activated, which drives the blocking plate 15 to move downward. The material trough 12, which is in a sealed state, is opened. The material falls from the inside of the material trough 12 into the storage box 13 under the action of gravity. The storage box 13 collects the material. Then, the rotating cylinder 7 continues to rotate, and the first placement plate 8 and the second placement plate 10 will drive the remaining material to continue to move into the material trough 12, thus providing a certain guiding effect and enabling the material to be unloaded quickly. The storage box 13 can receive the dried material as a whole. The hot air blower 19 can deliver hot air from the inside of the conveying pipe 18, and then deliver it into the inside of the drying cylinder 3 through the air delivery frame 16 and the air delivery head 17. Thus, the inside of the drying cylinder 3 is hot, and the material can be dried inside the drying cylinder 3. The above is the working principle of this utility model.
