Description

Technical Field

[0001] This utility model relates to the technical field of stone paint mixers, specifically to a feeding mechanism for a stone paint mixer. Background Technology

[0002] Real stone paint is a coating that closely resembles marble and granite in its decorative effect. It is mainly made of natural stone powder in various colors and is used to create a stone-like effect on building exteriors. Therefore, it is also known as liquid stone. Real stone paint is mainly made of high molecular polymers, natural colored stone sand, and related additives. After drying and curing, it becomes as hard as stone. It has the characteristics of fire resistance, water resistance, acid and alkali resistance, pollution resistance, non-toxicity, odorlessness, strong adhesion, and never fading. In the production process of real stone paint, a mixer is used for mixing. The real stone paint mixer (real stone paint blender) is a professional mechanical equipment for producing real stone paint coatings. Its core function is to achieve uniform mixing of high-viscosity raw materials such as colored sand and emulsion through efficient mixing technology, providing key production support for the architectural coatings industry. Due to the large size of the mixing equipment and the excessive height of the feed inlet, the raw materials are heavy when piled on the ground. It is necessary to use a shovel to feed the raw materials, which consumes a lot of physical strength, has low efficiency, and makes it difficult to ensure the continuity of feeding.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202320267326.5, application date 2023-02-21) provides a feeding device for a stone paint mixer, including a support frame, on which a feeding component is provided. The feeding component has two slots at its bottom and is attached to the mixer body. Four bolts are internally threaded onto the feeding component. The feeding component includes a tray, and the support frame is attached to the tray. Two electric push rods are fixedly connected to one side of the tray, and the other ends of the two electric push rods are fixedly connected to the corresponding side of a storage box. The storage box is attached to the tray. This feeding device for the stone paint mixer, by incorporating electric push rods, a storage box, a baffle, and a ramp, facilitates the conveying of materials into the mixer body via the feeding component. Simultaneously, different materials can be placed inside the storage box and conveyed simultaneously, thereby improving the working efficiency of the feeding device.

[0004] If the raw materials for stone paint have high moisture content, the particles are prone to sticking together. For example, powders stored in a humid environment, such as calcium carbonate powder and talc powder, will gradually aggregate into lumps after entering the hopper due to the humidity. These lumps may get stuck at the hopper's outlet, hindering the normal flow of materials and causing blockages. During the use of the above-mentioned device, it is impossible to avoid the stone paint from clogging inside the hopper, which forces the feeding process to be interrupted, greatly reducing the output per unit time and significantly decreasing the overall production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for a stone paint mixer, so as to solve the problem mentioned in the background art that it is impossible to avoid the stone paint from clogging inside the hopper, which leads to the forced interruption of the feeding process, greatly reduces the output per unit time, and significantly reduces the overall production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a stone paint mixer, comprising a base, a support frame fixedly connected to the upper surface of the base, a protective plate fixedly connected to the upper front side of the support frame, and auxiliary wheels fixedly connected to the upper outer side of the protective plate, the auxiliary wheels being symmetrically distributed about the center of the protective plate; a limiting rod fixedly connected to one end of the upper surface of the base near the support frame, the limiting rod being slidably connected to a fixing block, and a hopper fixedly connected to the front side of the fixing block, the hopper being slidably disposed on the front side of the support frame; a buffer pad fixedly connected to the lower rear side of the hopper, a drive shaft fixedly connected inside the hopper, and an auxiliary stirring component fixedly connected to the surface of the drive shaft, the auxiliary stirring component being rotatably disposed inside the hopper; a limiting plate fixedly connected to the lower rear side of the hopper, and a sliding column slidably connected inside the limiting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The feeding mechanism of this real stone paint mixer adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The feeding mechanism of the real stone paint mixer can effectively avoid material blockage inside the hopper by setting auxiliary stirring components and sliding columns, maintain good flow of material inside the hopper, and ensure that material can flow from the hopper into the conveying mechanism without interruption, thus avoiding feeding interruption caused by blockage and greatly improving feeding efficiency.

[0015] Furthermore, the rubber buffer pads ensure that the hopper surface is subjected to uniform force, allowing the material to be more evenly distributed inside the hopper and generating more stable vibrations, maintaining the normal flow of material inside the hopper and ensuring a smooth feeding process.

[0027] 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.

[0028] Example 1: The support frame 2, base 1, and protective plate 3 improve the stability of the device during operation, preventing deformation and damage due to excessive local stress. Figures 1-3 As shown: It includes a base 1, a support frame 2 fixedly connected to the upper surface of the base 1, a protective plate 3 fixedly connected to the upper front side of the support frame 2, and an auxiliary wheel 4 fixedly connected to the upper outer side of the protective plate 3. The auxiliary wheels 4 are symmetrically distributed about the center of the protective plate 3. A limit rod 5 is fixedly connected to one end of the upper surface of the base 1 near the support frame 2. A fixing block 17 is slidably connected to the limit rod 5. A hopper 14 is fixedly connected to the front side of the fixing block 17. The hopper 14 is slidably disposed in front of the support frame 2. A buffer pad 18 is fixedly connected to the lower rear side of the hopper 14. A drive shaft 15 is fixedly connected inside the hopper 14. An auxiliary stirring component 23 is fixedly connected to the surface of the drive shaft 15. The auxiliary stirring component 23 is rotatably disposed inside the hopper 14. A limit plate 19 is fixedly connected to the lower rear side of the hopper 14. A sliding column 20 is slidably connected inside the limit plate 19.

[0029] Workers pour the stone paint raw material into the hopper 14 using a conveying device. After conveying is complete, the workers start the motor 10, causing the metal pull rope 13 to drive the hopper 14 to slide in front of the support frame 2. Figure 1 and Figure 3As shown, as the hopper 14 slides in front of the support frame 2, the sliding column 20 strikes the buffer pad 18 on the surface of the hopper 14, causing the hopper 14 to vibrate. This prevents interruption of feeding due to blockage and greatly improves feeding efficiency. Figure 6 and Figure 7 As shown, when the gear 16 on the surface of the drive shaft 15 inside the hopper 14 meshes with the rack 9 on the surface of the fixed plate 8, the drive shaft 15 rotates, driving the auxiliary stirring component 23 on the surface to rotate inside the hopper 14, maintaining the normal flow of material inside the hopper 14 and ensuring a smooth feeding process. Figure 2 As shown, this allows the hopper 14 to rotate in front of the support frame 2, enabling automatic feeding of the stone paint raw materials inside the hopper 14, greatly improving the production pace. Figure 2 As shown, the support frame 2 and protective plate 3 improve the stability of the device during operation, prevent the device from deforming and being damaged due to excessive local stress, ensure that the feeding device can still operate stably under full load, and at the same time ensure the overall stability and reliability of the feeding device.

[0030] Example 2: In this example, unlike Example 1, the size of the discharge port of the hopper 14 can be precisely adjusted by using the support frame 2, the motor 10, and the metal pull rope 13. This allows for precise quantitative feeding of each material according to the formula, ensuring the stability and consistency of the quality of the stone paint product. Figures 4-5 As shown: A fixing plate 8 is fixedly connected to the upper surface of the base 1 near the protective plate 3, and the fixing plates 8 are symmetrically distributed about the center of the support frame 2. A rack 9 is fixedly connected to the surface of the fixing plate 8 near the support frame 2. A motor 10 is fixedly connected to the upper surface of the base 1 away from the support frame 2, and a rotating shaft 12 is fixedly connected to the output end of the motor 10. A movable plate 11 is fixedly connected to the upper left side of the base 1. A rotating shaft 12 is rotatably arranged inside the movable plate 11. One end of a metal pull rope 13 is fixedly connected to the surface of the rotating shaft 12, and the other end of the metal pull rope 13 is fixedly connected to a hopper 14. The metal pull rope 13 is slidably arranged on the surface of the auxiliary wheel 4. A gear 16 is fixedly connected to the surface of the transmission shaft 15, and the gear 16 is rotatably arranged outside the hopper 14. The gear 16 and the rack 9 are meshed.

[0031] When the motor 10 is working, it drives the output shaft 12 to rotate inside the moving plate 11, such as... Figure 4 As shown, with the rotation of the shaft 12, the metal pull rope 13 on the surface retracts towards the surface, pulling the hopper 14 at the other end of the metal pull rope 13, causing the hopper 14 to slide on the front side of the support frame 2, and the fixing block 17 on the rear side of the hopper 14 to slide on the surface of the limiting rod 5, as shown. Figure 6 As shown, the metal pull rope 13 slides on the surface of the auxiliary wheel 4 outside the protective plate 3, reducing the friction between the metal pull rope 13 and the device, and extending the service life of the device, such as... Figure 4 As shown, when the gear 16 on the surface of the drive shaft 15 meshes with the rack 9 on the surface of the fixed plate 8, the drive shaft 15 drives the hopper 14 to rotate in front of the support frame 2, causing the material inside the hopper 14 to flow into the interior of the stone paint mixer, such as... Figure 5 As shown, this ensures that the material flow is uniform and stable throughout the entire feeding process. This not only improves the working efficiency of the device but also makes the feeding process more efficient, greatly accelerating the production pace.

[0032] In embodiment three, unlike embodiment two, the connecting plate 6, sliding column 20, and buffer spring 22 effectively prevent material blockage inside the hopper 14, maintaining good material flow within the hopper 14. Figures 6-7 As shown: A connecting plate 6 is fixedly connected to one end of the upper surface of the base 1 near the support frame 2, and an upper protrusion 7 is fixedly connected to one end of the surface of the connecting plate 6 near the hopper 14. The upper protrusions 7 are evenly distributed on the surface of the connecting plate 6, and the surface of the upper protrusions 7 is inclined. A lower protrusion 21 is fixedly connected to one end of the surface of the sliding column 20 near the connecting plate 6, and the surface of the lower protrusion 21 is inclined. One end of the buffer spring 22 is fixedly connected to the surface of the sliding column 20, and the other end of the buffer spring 22 is fixedly connected to the limit plate 19.

[0033] As the hopper 14 slides in front of the support frame 2, it causes the limiting plate 19 at the lower rear end of the hopper 14 to slide on the upper end of the base 1. Figure 6 As shown, when the lower protrusion 21 on the surface of the sliding column 20 contacts the upper protrusion 7 on the surface of the connecting plate 6, the upper protrusion 7 pushes the lower protrusion 21, causing the sliding column 20 to slide inside the limiting plate 19, and causing the buffer spring 22 on the surface of the limiting plate 19 to extend towards the surface of the sliding column 20, thereby causing the sliding column 20 to strike the buffer pad 18 on the surface of the hopper 14, such as... Figure 7 As shown, the hopper 14 vibrates, ensuring that the material can flow continuously from the hopper 14 into the conveying mechanism, avoiding interruption of feeding due to blockage, greatly improving feeding efficiency. The evenly spaced distribution of the upper protrusions 7 improves the working efficiency of the device, and the rubber buffer pad 18 ensures that the surface of the hopper 14 is evenly stressed, allowing the material to be more evenly distributed inside the hopper 14, and the vibration is more stable, maintaining the normal flow of material in the hopper 14 and ensuring a smooth feeding process.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
