Technical Field
[0001] This utility model relates to the technical field of stone paint mixers, specifically to a feeding device for a high-efficiency stone paint mixer. Background Technology
[0002] Stone paint is a type of coating that closely resembles the decorative effect of marble and granite. It is mainly made from natural sand of various colors, and most of the raw materials are in powder form. The stone paint mixer, also known as the stone paint blender, is a professional production equipment for producing stone paint coatings. Because the mixer is large, it is very inconvenient to feed the material from a height, so it is necessary to use some lifting and feeding equipment to assist in feeding the material.
[0003] Existing auger conveyors are the most commonly used conveying equipment. During use, they are typically supported by a fixed bracket welded to their bottom, tilting them upwards to feed the stone paint mixer. However, using a fixed bracket for support results in poor adjustability, making it inconvenient to adjust the discharge port or position of the feeding device. To solve these problems, an automatic lifting and feeding device for a stone paint mixer can be described in existing technology (Chinese patent application number CN201820849054.9, application date 2018-06-04). This feeding device, through the vertical mobility of the screw and support rod, allows for easy adjustment of the tilt of the feeding pipe, thus facilitating the adjustment of the discharge port height. The casters at the bottom of the support legs allow for quick and easy adjustment of the position of the feeding pipe and discharge port.
[0004] Although the above-mentioned device can solve the problem of adjusting the position of the discharge port, there are still problems when using the device. The raw materials inside the feed hopper are conveyed by the auger. At this time, a certain amount of powder will remain inside the feed hopper. Manual intervention is required to process the residual powder, which is a rather cumbersome process.
[0005] Therefore, we proposed that the feeding device of the high-efficiency stone paint mixer can effectively solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a feeding device for a high-efficiency stone paint mixer, so as to solve the problem mentioned in the background art that the raw materials inside the feeding hopper of the current feeding device on the market are conveyed by the auger, and at this time, a certain amount of powder will remain inside the feeding hopper. At this time, manual intervention is required to process the residual powder, which is a cumbersome process.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a high-efficiency stone paint mixer, comprising a movable base with a locking mechanism, wherein a conveying pipe is connected to the top of the movable base via a support structure, a discharge port is provided at the bottom left side of the conveying pipe, and a feeding hopper is provided at the upper right side, wherein a driving component is installed at the right end of the conveying pipe, and the driving component is connected to the auger conveying rod inside the conveying pipe to drive it to convey raw materials; the auger conveying rod is connected to a dispersing component for dispersing the raw materials in the feeding hopper via a synchronizing component, and the dispersing component is linked to a striking mechanism, which can apply vibration to the feeding hopper to avoid raw material accumulation.
[0008] As a preferred technical solution of this application, the support structure includes a support rod and a hydraulic push rod fixed to the top of the movable base. The top of the support rod is rotatably connected to the bottom of the conveying pipe. A sliding sleeve is rotatably connected to the top of the hydraulic push rod. The sliding sleeve is slidably fitted on the outside of the guide rail. The guide rail is fixedly connected to the conveying pipe. Through the rotatable connection between the support rod and the conveying pipe, and in conjunction with the hydraulic push rod driving the sliding sleeve to slide along the guide rail, the tilt angle of the conveying pipe can be flexibly adjusted, realizing stepless adjustment of the discharge port height, adapting to the inlet position of different specifications of mixers, and improving the versatility of the equipment.
[0009] As a preferred technical solution of this application, the guide rail is fixed on the outer wall of the conveying pipe, and the sliding sleeve forms a sliding fit structure with the outer wall of the conveying pipe through the guide rail. The fixed connection between the guide rail and the conveying pipe ensures that the sliding sleeve can stably drive the conveying pipe to rotate around the support rod when sliding, avoids the conveying pipe shaking during the adjustment process, improves the stability and accuracy of the angle adjustment, and ensures the continuity of the feeding process.
[0010] As a preferred technical solution of this application, the driving component is a drive motor, the synchronizing component is a synchronous belt, and the dispersing component is a stirring rod rotatably disposed in the feed hopper. The stirring rod is connected to the auger conveyor rod via the synchronous belt. The drive motor drives both the auger conveyor rod and the stirring rod simultaneously, and the synchronous belt enables them to operate synchronously without the need for an additional power source, thus saving energy. The stirring rod can disperse and stir the raw materials in the feed hopper, preventing powder from clumping and blocking the feed inlet, and ensuring the smooth flow of raw materials.
[0011] As a preferred technical solution of this application, one end of the stirring rod extending outside the feed hopper is fixed to one side of the striking mechanism. The striking mechanism includes a rotating rod fixed to the stirring rod. Several striking rods are slidably arranged inside the rotating rod. The outer side of each striking rod is connected to the interior of the rotating rod via a return spring. A through hole is provided inside the rotating rod, and the other end of the through hole is connected to an air delivery disc. The outer end of the air delivery disc is connected to an air jet strip via a connecting pipe. The striking mechanism includes a rotating rod fixedly connected to the dispersing component. The rotating rod has several slidable striking rods inside its protruding part. These striking rods are connected to the inner wall of the rotating rod via a return spring. A through hole is opened inside the rotating rod, connecting to an air conveying disc. The air conveying disc is connected to an air jet strip via a connecting pipe. The stirring rod drives the rotating rod to rotate synchronously. Under the action of centrifugal force and the return spring, the striking rods periodically impact the feed hopper, generating vibration to prevent raw material accumulation. Simultaneously, as the striking rods slide, compressed air is sent to the air jet strip through the through hole, air conveying disc, and connecting pipe, forming a dual cleaning process of "vibration and air blowing," thoroughly resolving the problem of raw material residue on the inner wall of the feed hopper.
[0012] As a preferred technical solution of this application, a set of rubber rings is nested at one end of the striking rod that extends into the rotating rod to facilitate the compression and delivery of gas. A one-way air inlet is provided at the outer end of the rotating rod, and one end of the air jet strip is installed in an inclined downward position inside the feed hopper. A one-way air outlet is installed inside the air jet strip. The rubber rings enhance the sealing between the striking rod and the rotating rod, ensuring effective air compression. The one-way air inlet ensures a continuous supply of air inside the rotating rod, and the one-way air outlet prevents gas backflow and increases the jet pressure. The inclined downward installation of the air jet strip can accurately blow away the raw materials remaining on the inner wall of the feed hopper, enhancing the cleaning effect and reducing manual intervention.
[0013] As a preferred technical solution of this application, the striking rods are distributed in several groups at equal angles with respect to the center of the rotating rod, and rubber balls are provided on the outer side of the striking rods. The outer side of the rubber balls corresponds to the two groups of fixed plates on one side of the feed hopper. The equal angle distribution of the striking rods can make the feed hopper body bear force evenly, the vibration effect more balanced, and avoid local material accumulation. The rubber balls reduce the noise during the striking and the wear on the feed hopper body, and extend the service life of the equipment. The plates and rubber balls can amplify the vibration amplitude when they collide, further improving the anti-accumulation effect.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The feeding device of this high-efficiency stone paint mixer uses a drive motor to drive the auger conveyor rod, which synchronously links the mixing rod in the feeding hopper to disperse the raw materials; the mixing rod drives the striking mechanism, causing the striking rod to vibrate the feeding hopper, preventing raw materials from accumulating and remaining. The support structure allows for adjustment of the conveying pipe angle, improving adaptability, reducing manual intervention, and increasing feeding efficiency, as detailed below:
[0015] 1. When the drive motor drives the auger conveyor rod, the stirring rod in the feed hopper body is linked by the synchronous belt to disperse the raw materials and prevent them from clumping. At the same time, the stirring rod drives the striking mechanism, so that the striking rod on the rotating rod continuously strikes the feed hopper body under the action of the return spring. Combined with the air jet strip, it effectively prevents the accumulation and residue of raw materials, eliminating the need for manual cleaning and improving the smoothness of feeding.
[0016] 2. In the support structure, the hydraulic push rod can slide along the guide rail through the sliding sleeve. Combined with the rotational connection between the support rod and the conveying pipe, the angle of the conveying pipe can be flexibly adjusted to meet the feeding height requirements of different mixers and enhance the versatility of the equipment.

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, 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 Figures 1-6This utility model provides the following technical solution: a feeding device for a high-efficiency stone paint mixer.
[0026] Example 1: This example provides a feeding device for a high-efficiency stone paint mixer, which solves the problems of raw material accumulation in the feed hopper 12 and inconvenient adjustment of the feeding angle during the feeding process of stone paint raw materials. Its structure is as follows: Figure 1 -Appendix Figure 6 As shown, it specifically includes: casters with locking mechanisms at the bottom, allowing for flexible movement and fixed position, such as... Figure 1 , Figure 2 A support rod 2 is fixed to the top left side, and a hydraulic push rod 3 is fixed to the right side. The top of the support rod 2 is rotatably connected to the bottom of the conveying pipe 6, and the top of the hydraulic push rod 3 is rotatably connected to a sliding sleeve 4. The sliding sleeve 4 is slidably fitted on the outside of the guide rail 5. The guide rail 5 is fixed to the top of the movable base 1 and extends along the length of the conveying pipe 6. By extending and retracting the hydraulic push rod 3, the sliding sleeve 4 can be driven to slide along the guide rail 5, thereby adjusting the tilt angle of the conveying pipe 6. A discharge port 7 is opened at the bottom left side of the conveying pipe 6, and a feed hopper 12 is welded to the upper right side, with an auger conveying rod 9 rotatably installed inside. Figure 4 As shown, a drive motor 8 is bolted to the right end of the conveying pipe 6. The output end of the drive motor 8 is fixed to the right end of the auger conveyor rod 9 via a coupling. Starting the drive motor 8 can drive the auger conveyor rod 9 to rotate, conveying the raw material in the feed hopper 12 along the conveying pipe 6 to the discharge port 7 for discharge; Figure 3 As shown, the outer side of the right end of the auger conveyor rod 9 is connected to the stirring rod 11 via a synchronous belt 10. The stirring rod 11 is rotatably installed inside the feed hopper 12 and rotates synchronously with the auger conveyor rod 9 to disperse the raw materials. A rotating rod 13 is welded to one end of the stirring rod 11 that extends out of the feed hopper 12, forming the main body of the striking mechanism.
[0027] Push the movable base 1 to the vicinity of the mixer's feed inlet, and fix the base by stepping on the brake pads to prevent the device from shifting during feeding. Adjust the angle of the conveying pipe 6 by using the hydraulic push rod 3 so that the discharge port 7 is aligned with the mixer. Put the real stone paint raw material into the feed hopper 12, start the drive motor 8, and the auger conveyor rod 9 rotates to convey the material. At the same time, the mixing rod 11 rotates synchronously to disperse the raw material and prevent clumping, thereby achieving the conveying effect.
[0028] Example 2: Based on Example 1, this example further explains the specific operation of the striking mechanism and the air jet structure;
[0029] like Figure 5As shown: Multiple sliding holes are radially opened inside the rotating rod 13, and a striking rod 14 is slidably installed in each sliding hole. The inner end of the striking rod 14 is connected to the bottom of the sliding hole through a return spring 15. When the stirring rod 11 rotates synchronously with the auger conveying rod 9, one end of it extending out of the outside of the feed hopper 12 drives the rotating rod 13 to rotate coaxially. The striking rods 14, radially distributed inside the rotating rod 13, generate centrifugal force due to rotation, overcoming the elastic force of the return spring 15 and sliding outward until the rubber ball at the outer end strikes the fixed plates on both sides of the feed hopper 12. After the impact, the contraction force of the return spring 15 is greater than the centrifugal force, pulling the striking rods 14 back into the rotating rod 13. As the rotating rod 13 continues to rotate, the centrifugal force drives the striking rods 14 to extend outward and strike again. The resulting periodic cycle frequency is related to the rotation speed of the stirring rod 11. In addition, since the striking rods 14 are distributed at equal angles about the center of the rotating rod 13, and the impact point of the rubber ball and the plate covers the outer wall of the feed hopper 12, the feed hopper 12 can vibrate, causing the attached raw materials to fall off due to vibration and avoiding local accumulation.
[0030] like Figure 6 As shown: The rotating rod 13 has a through hole 16 inside, one end of which is connected to the sliding hole, and the other end is connected to the air conveying plate 17 through a rotary joint. The air conveying plate 17 is connected to the air jet strip 19 through the connecting pipe 18. The air jet strip 19 is fixed to the inner wall of the feed hopper 12 with an inclined downward direction and has a built-in one-way air outlet. The rubber ring nested in the inner end of the striking rod 14 enhances the sealing with the sliding hole of the rotating rod 13. When the striking rod 14 slides outward, its inner space shrinks, and the air is compressed and forced into the air conveying plate 17 through the through hole 16. At the same time, the one-way air inlet at the outer end of the rotating rod 13 automatically opens to replenish the air into the sliding hole. The compressed air is diverted through the air conveying plate 17 to the connecting pipe 18 and finally delivered to the air jet strip 19 fixed to the inner wall of the feed hopper 12. The air jet strip 19 is set with an inclined downward direction and has a built-in one-way air outlet to prevent the raw material from entering the pipeline in reverse. The high-pressure airflow directly blows away the fine powder adhering to the inner wall of the hopper, forming a "shedding force" with the vibration. The system works synergistically to thoroughly remove any residual raw materials that were not completely removed by the impact and vibration. Vibration loosens clumps or sticky materials from the hopper wall, while the airflow blows the loosened fine particles to the feed inlet, where they are promptly conveyed by the auger conveyor rod 9 to prevent secondary accumulation. At the same time, the cushioning effect of the rubber balls reduces impact noise and hopper wear. In addition, the air jet strip 19 is located at the corner of the right inner wall of the feed hopper 12 to prevent raw materials from accumulating at the corner due to gravity. This entire process requires no manual intervention, significantly improving feeding efficiency and raw material utilization.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
