Description

Technical Field

[0001] This utility model relates to the field of seed coating technology, specifically a multi-functional spraying device for a coating machine. Background Technology

[0002] Coating machines are mainly used in the pharmaceutical, chemical, and food industries. They can perform organic film coating, water-soluble film coating, and sustained-release coating on materials such as tablets, pills, and candies. The working principle of the coating machine is to continuously and uniformly coat the material by rotating the bed, so that a uniform coating film is formed on the surface of the material, thereby achieving the effects of protecting the material, improving stability, and beautifying the appearance.

[0003] Seed coating is a seed processing technology that involves coating seeds with active ingredients such as pesticides, fertilizers, growth regulators, and other auxiliary materials. It involves applying a coating agent to the surface of selected seeds, thus granulating them. Types include rotary drum, floating, and combined types. It consists of a coating tank, mixing, metering, spraying, air supply, power, and transmission devices.

[0004] When using existing seed coating machine spraying devices, the spraying device is often fixed inside the coating machine. When there is a lot of material to be coated, the fixed spraying position cannot be adjusted, and the material on the edge may be sprayed unevenly, affecting the coating effect. This leads to a longer coating operation time and reduces the work efficiency of the operator. Therefore, a multi-functional spraying device for coating machines is needed to meet people's needs. Utility Model Content

[0005] The purpose of this invention is to provide a multi-functional spraying device for coating machines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional spraying device for a coating machine, comprising a device body and a liquid storage tank, wherein the device body and the liquid storage tank are connected by a liquid delivery pipe, and a spraying mechanism and a rotating mechanism are arranged inside the device body; the spraying mechanism is installed on a baffle that passes through the accommodating chamber of the rotating mechanism, and sprays the material inside the rotating mechanism; the spraying mechanism includes a fixed plate, a slider, a spraying pipe, a fixing component, and a nozzle, wherein the fixed plate is fixed to the baffle, and the slider is slidably installed on the fixed plate; the slider is provided with a fixing bolt for adjusting the tightness between the slider and the fixed plate, the spraying pipe is installed on the slider and connected to the liquid delivery pipe through a connecting pipe, the fixing component is fixed to the other end of the connecting pipe through a connecting sleeve, and the nozzle is installed on the fixing component and connected to the spraying pipe. The spraying mechanism composed of the fixed plate, slider, spraying pipe, fixing component, and nozzle achieves precise spraying of materials. The slider can slide on the fixed plate, allowing adjustment of the nozzle position to accommodate materials of different sizes or shapes.

[0007] Further describing the aforementioned solution, the rotating mechanism includes a roller installed within the main body of the device. Multiple baffles are installed on the inner ring of the roller, and toothed blocks are installed on the outer ring of the roller. A movable groove is formed within the main body of the device, and a motor is installed within the movable groove. The motor drives the toothed blocks and rotates the roller via gears. The cooperation between the toothed blocks and the motor gears drives the roller to rotate, achieving automatic material turnover and ensuring that the material surface can fully contact the sprayed liquid.

[0008] Optionally, a glass cover is installed at the feeding port on one side of the main body of the device. A locking device is installed at one end of the glass cover, and a rotary switch is installed at one end of the locking device. The locking device is used to lock the glass cover onto the main body of the device. The design of the glass cover facilitates observation of the internal working conditions, while the locking device and rotary switch ensure operational safety.

[0009] More preferably, the liquid spraying mechanism has at least two sets of sliders, spray pipes, fixtures and nozzles, and each set of spray pipes is connected by a retractable liquid delivery pipe. This ensures the uniformity and efficiency of the liquid spraying. Especially when processing materials with more edge parts, the retractable liquid delivery pipe allows the components in the liquid spraying mechanism to move as needed without affecting the liquid transmission, improving the flexibility and applicability of the equipment.

[0010] Furthermore, both sides of the fixed plate and the slider are provided with grooves to accommodate ball bearings. The ball bearings are installed in the grooves, and the slider slides on the fixed plate via the ball bearings. A baffle is provided at the end of the groove of the slider to prevent the ball bearings from falling out. The ball bearing grooves on both sides of the slider reduce friction, allowing the slider to slide more smoothly on the fixed plate, increasing the service life and working efficiency of the equipment. The liquid storage tank is also equipped with a liquid pump connected to the infusion pipe. The liquid pump is used to draw liquid from the liquid storage tank and deliver it to the spray pipe through the infusion pipe, ensuring a stable liquid supply.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) By setting a fixed plate and a slider, when the raw material needs to be coated, the raw liquid is transported to the fixed part through the spray pipe and sprayed through the nozzle. The slider position is fixed by rotating the slider at the top of the slider. When the slider is pushed to move, the ball rotates in the groove, making the sliding more convenient. When the slider moves to the appropriate position, one end of the fixing bolt is tightened to abut against the fixed plate to fix the position of the slider. By adjusting the position of the two sliders, the area covered by the spray is guaranteed, which improves the production efficiency.

[0013] (2) By setting baffles and toothed blocks, when the material rotates in the roller, the baffles make the material spread evenly, which is convenient for coating. By starting the motor to drive the gear to rotate, the meshing toothed blocks will rotate. The toothed blocks drive the roller to continuously stir the material, making the surface of the material more evenly coated, thus improving the applicability of the device.

Detailed Implementation

[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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figures 1-6 As shown, this embodiment discloses a multi-functional liquid spraying device for a coating machine, including a device body 1 and a liquid storage tank 4. The device body 1 and the liquid storage tank 4 are connected by a liquid delivery pipe 5. A liquid pump connected to the liquid delivery pipe 5 is installed inside the liquid storage tank 4. The liquid pump is used to draw liquid from the liquid storage tank 4 and deliver it to the spraying pipe 26 through the liquid delivery pipe 5, ensuring a stable liquid supply. The device body 1 is internally equipped with a spraying mechanism 2 and a rotating mechanism 3.

[0027] like Figures 2 to 6 As shown, the spraying mechanism 2 is installed on the baffle 32 that passes through the receiving chamber of the rotating mechanism 3. The baffle 32 is fixed inside the main body 1 of the device. The spraying mechanism 2 sprays the material inside the rotating mechanism 3. The spraying mechanism 2 includes a fixed plate 21, a slider 22, a spray pipe 26, a fixing member 28, and a nozzle 29. The fixed plate 21 is fixed on the baffle 32, and the slider 22 is slidably installed on the fixed plate 21. The slider 22 is provided with fixing bolts 25 to adjust the tightness between the slider 22 and the fixed plate 21. The spray pipe 26 is installed on the slider 22 and connected to the infusion pipe 5 through a connecting pipe 9. The fixing member 28 is fixed to the other end of the connecting pipe 9 through a connecting sleeve 27. The nozzle 29 is installed on the fixing member 28 and connected to the spray pipe 26. The spraying mechanism 2, composed of the fixed plate 21, slider 22, spray pipe 26, fixing member 28, and nozzle 29, achieves precise spraying of materials. The slider 22 can slide on the fixed plate 21, allowing the position of the nozzle 29 to be adjusted to accommodate materials of different sizes or shapes. In this embodiment, the spray mechanism 2 has two sets of slider 22, spray pipe 26, fixing member 28, and nozzle 29, and each set of spray pipe 26 is connected by a retractable inlet pipe 5. This ensures the uniformity and efficiency of the spray, especially when processing materials with relatively narrow edges. The retractable inlet pipe 5 allows the components in the spray mechanism 2 to move as needed without affecting the liquid transfer, improving the flexibility and applicability of the equipment. In some embodiments, the number of spray mechanisms 2 can be increased or decreased as needed.

[0028] To accommodate different coating requirements, the nozzle 29 can be designed to be replaceable to adapt to materials of different particle sizes and shapes, or to allow selection of a suitable nozzle 29 based on the viscosity of different liquids. In other embodiments, a precision flow controller is added at the connection between the spray pipe 26 and the delivery pipe 5, enabling precise adjustment of the spray volume as needed to ensure coating uniformity and quality. In other embodiments, the angle of the nozzle 29 can be adjusted to ensure that the material surface is adequately covered.

[0029] like Figure 5 , 6 As shown in this embodiment, both sides of the fixed plate 21 and the slider 22 are provided with grooves 23 for accommodating balls 24. The balls 24 are installed in the grooves 23, and the slider 22 slides on the fixed plate 21 via the balls 24. A baffle is provided at the end of the groove 23 of the slider 22 to prevent the balls 24 from falling out. The ball grooves 23 on both sides of the slider 22 reduce friction, allowing the slider 22 to slide more smoothly on the fixed plate 21, increasing the service life and working efficiency of the equipment.

[0030] like Figure 3 As shown, the rotating mechanism 3 includes a roller 31 installed inside the main body 1 of the device. Multiple baffles 32 are installed on the inner ring of the roller 31, and toothed blocks 33 are installed on the outer ring of the roller 31. A movable groove 34 is provided inside the main body 1, and a motor 35 is installed within the movable groove 34. The motor 35 drives the toothed blocks 33 and rotates the roller 31 via gears 36. The interaction between the toothed blocks 33, the motor 35, and the gears 36 drives the roller 31 to rotate, achieving automatic material turnover and ensuring that the material surface can fully contact the sprayed liquid. In other embodiments, the motor 35 should have a speed-changing function, allowing adjustment of the speed according to material characteristics and process requirements to improve coating efficiency and effectiveness. To prevent vibration during high-speed operation, a counterweight can be added inside the main body 1 if necessary. The baffles 32 should be made of wear-resistant materials that are not easily reactive with the drug, such as stainless steel or engineering plastics.

[0031] like Figure 2 As shown, a glass cover 6 is installed at the feeding port on one side of the main body 1 of the device. A locking lock 7 is installed at one end of the glass cover 6, and a rotary switch 8 is installed at the other end of the locking lock 7. The locking lock 7 is used to lock the glass cover 6 onto the main body 1 of the device. The design of the glass cover 6 facilitates observation of the internal working conditions, while the locking lock 7 and the rotary switch 8 ensure the safety of operation.

[0032] To gain a more thorough and comprehensive understanding of the disclosure of this utility model, its principles will be further explained below in conjunction with its usage.

[0033] In use, the locking of the fixed lock 7 is released by turning the rotary switch 8, opening one end of the glass cover 6. The material to be coated is poured into the roller 31. The motor 35 is started, driving the gear 36 to rotate, which in turn drives the toothed block 33 meshing with the gear 36 to rotate. With the continuous rotation of the roller 31, the material is blocked and stirred by the baffle 32. The raw liquid is transported to the connecting pipe 9 through the liquid storage tank 4 and the liquid delivery pipe 5. The connecting pipe 9 transmits the raw liquid to the spray pipe 26, and the spray pipe 26 delivers the raw liquid to the nozzle 29 for atomized spraying. When the spray needs to be adjusted... When the area is being sprayed, rotating the top slider 22 releases the fixation of the slider 22's position. As the slider 22 moves, the ball bearing 24 rotates within the groove 23, making the sliding more convenient. Once the slider 22 is in the appropriate position, tightening one end of the fixing bolt 25 against the fixing plate 21 fixes the position of the slider 22. Adjusting the positions of the two sliders 22 adjusts the spray area, resulting in more uniform material coating and improved production efficiency. The coating condition can be observed through the glass cover 6, and the coated material can be removed, improving the device's versatility. After completing a batch of production, the inner cavity can be automatically cleaned by the spray device, reducing manual intervention and the risk of cross-contamination.

[0034] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention. This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and embodiments are to be considered exemplary only, and the true scope and spirit of the invention are indicated by the foregoing claims.

[0035] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
