Description

Technical Field

[0001] This utility model relates to the field of stone paint production kettle technology, specifically a stone paint production kettle wall scraping device. Background Technology

[0002] Real stone paint is a type of coating that closely resembles the decorative effect of marble and granite. It is mainly made of natural stone powder in various colors and is used to create a stone-like effect on the exterior walls of buildings. Therefore, it is also known as liquid stone.

[0003] During the mixing process of real stone paint production, material adheres to the vessel wall, which leads to insufficient mixing of the real stone paint. Therefore, in actual production, a corresponding scraper is needed inside the real stone paint production vessel to scrape the material off the vessel wall. However, the existing scraper is always in contact with the vessel wall, which is prone to wear and reduces the scraping effect. Based on this, a scraper device for real stone paint production vessel is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a scraping device for a stone paint production kettle in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wall scraping device for a stone paint production vessel, comprising a vessel body assembly consisting of a mixing vessel, a feed inlet, and a discharge outlet. The feed inlet is located on one side of the top of the mixing vessel, and the discharge outlet is fixed to the middle of the bottom of the mixing vessel and communicates with the inner cavity of the mixing vessel. A dual-mode mixing assembly extending into the interior of the mixing vessel is provided on the top of the mixing vessel. The dual-mode mixing assembly includes a mixing unit, a wall scraping switching unit, and a lifting unit.

[0006] The stirring unit is used to stir the materials inside the stirring vessel;

[0007] The lifting unit is used to lift the stirring unit, thereby enabling the expansion or contraction of the wall scraping switching unit. The expansion of the wall scraping switching unit is used to scrape the inner wall of the stirring vessel.

[0008] As a further embodiment of this utility model: the stirring unit includes a drive motor, a lifting seat, a rotating shaft, stirring blades, and a rectangular stirring frame;

[0009] The drive motor is fixedly installed on the top of the lifting seat. The drive motor and the lifting seat are located above the top of the mixing tank. The output end of the drive motor passes through the lifting seat and is fixedly connected to the rotating shaft. The rotating shaft extends into the interior of the mixing tank. The stirring blades and the rectangular stirring frame are fixed on the outside of the rotating shaft and located inside the mixing tank. The rectangular stirring frame is distributed on the outside of the stirring blades.

[0010] The stirring blades and rectangular stirring frame are driven by a drive motor to rotate in a circular motion to stir the materials inside the stirring vessel.

[0012] The fixed cylinder seat is installed at the top center of the mixing tank. The rotating sleeve is connected to the inside of the fixed cylinder seat by a limiting ball and protrudes into the inside and top of the mixing tank. The conical cylinder is fixed to the bottom of the rotating sleeve. The rotating shaft completely passes through the rotating sleeve and the conical cylinder.

[0013] The horizontal limiting groove is symmetrically opened on both sides of the rectangular stirring frame and runs through the upper and lower ends of the rectangular stirring frame. The wall scraper is horizontally slidably connected to the inner side of the horizontal limiting groove. The top horizontal part of the wall scraper extends to the top of the conical surface of the conical cylinder. The drag-reducing ball is rotatably connected to the top horizontal part of the wall scraper and fits against the conical surface of the conical cylinder.

[0014] The two ends of the spring are respectively fixed to one side of the vertical part at the top of the wall scraper and the side of the inner wall at the top of the horizontal limiting slide groove. The spring is used to provide the wall scraper with a thrust toward the conical cylinder.

[0015] In normal operation, the spring retracts to the inner side of the horizontal limit slide groove and will not contact the inner wall of the mixing vessel. The rectangular stirring frame moves down so that the top horizontal part of the wall scraper is pressed against the conical surface of the conical cylinder to make the wall scraper move horizontally and fit against the side of the inner wall of the mixing vessel. The bottom of the rectangular stirring frame fits against the bottom of the inner wall of the mixing vessel to realize the wall scraping operation on the side and bottom of the inner wall of the mixing vessel.

[0016] As a further embodiment of this utility model: the lifting unit includes an electric push rod, and two electric push rods are provided.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] By setting up a dual-mode stirring component, the device can operate in two modes: pure stirring mode and stirring and scraping mode. When producing real stone paint, the stirring and scraping mode can be selectively activated during material stirring and during unloading. This not only prevents materials from adhering to the inner wall of the mixing vessel, ensuring thorough mixing, but also prevents the scraping component from constantly sticking to the inner wall of the mixing vessel, which would cause severe wear. This allows the scraping effect of the device to remain stable for a long time. Attached Figure Description

[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] Please see Figures 1-4In this embodiment of the present invention, a wall scraping device for a stone paint production vessel includes a vessel body assembly 1 consisting of a mixing vessel 101, a feed inlet 102, and a discharge outlet 103. The feed inlet 102 is located on one side of the top of the mixing vessel 101, and the discharge outlet 103 is fixed to the middle of the bottom of the mixing vessel 101 and communicates with the inner cavity of the mixing vessel 101. A dual-mode mixing assembly 2 extending into the interior of the mixing vessel 101 is provided on the top of the mixing vessel 101. The dual-mode mixing assembly 2 includes a mixing unit, a wall scraping switching unit, and a lifting unit. The mixing unit is used to mix the material inside the mixing vessel 101, and the lifting unit is used to lift the mixing unit, thereby enabling the wall scraping switching unit to expand or contract. The expansion of the wall scraping switching unit is used to scrape the inner wall of the mixing vessel 101.

[0029] The stirring unit includes a drive motor 201, a lifting seat 202, a rotating shaft 203, stirring blades 204, and a rectangular stirring frame 205;

[0030] The drive motor 201 is fixedly installed on the top of the lifting seat 202. The drive motor 201 and the lifting seat 202 are located above the top of the mixing vessel 101. The output end of the drive motor 201 passes through the lifting seat 202 and is fixedly connected to the rotating shaft 203. The rotating shaft 203 extends into the interior of the mixing vessel 101. The stirring blade 204 and the rectangular stirring frame 205 are fixed on the outside of the rotating shaft 203 and located inside the mixing vessel 101. The rectangular stirring frame 205 is distributed on the outside of the stirring blade 204.

[0031] The stirring blades 204 and the rectangular stirring frame 205 are driven by the drive motor 201 to rotate in a circular motion to achieve stirring of the materials inside the stirring vessel 101.

[0032] The wall scraping switching unit includes a horizontal limiting slide 206, a wall scraping component 207, a spring 208, a drag-reducing ball 209, a fixed cylinder seat 210, a rotating sleeve 211, and a conical cylinder 212.

[0033] The fixed cylinder seat 210 is installed at the top center of the mixing vessel 101. The rotating sleeve 211 is rotatably connected to the inside of the fixed cylinder seat 210 by the limiting ball 214 and protrudes into the inside and top of the mixing vessel 101. The conical cylinder 212 is fixed to the bottom of the rotating sleeve 211. The rotating shaft 203 completely penetrates the rotating sleeve 211 and the conical cylinder 212.

[0034] A horizontal limiting groove 206 is symmetrically opened on both sides of a rectangular stirring frame 205 and passes through the upper and lower ends of the rectangular stirring frame 205. A wall scraper 207 is horizontally slidably connected to the inner side of the horizontal limiting groove 206. The top horizontal part of the wall scraper 207 extends to the top of the conical surface of the conical cylinder 212. A drag-reducing ball 209 is rotatably connected to the top horizontal part of the wall scraper 207 and fits against the conical surface of the conical cylinder 212.

[0035] The two ends of the spring 208 are respectively fixed to one side of the vertical part at the top of the wall scraper 207 and the side of the inner wall at the top of the horizontal limiting slide groove 206. The spring 208 is used to provide the wall scraper 207 with a thrust toward the conical cylinder 212.

[0036] In normal operation, the spring 208 retracts to the inner side of the horizontal limit groove 206 and does not contact the inner wall of the mixing vessel 101. The rectangular stirring frame 205 moves down so that the top horizontal part of the wall scraper 207 is pressed against the conical surface of the conical cylinder 212 to make the wall scraper 207 move horizontally and fit against the side of the inner wall of the mixing vessel 101. The bottom of the rectangular stirring frame 205 fits against the bottom of the inner wall of the mixing vessel 101 to realize the wall scraping operation on the side and bottom of the inner wall of the mixing vessel 101.

[0037] The lifting unit includes an electric push rod 215. There are two electric push rods 215. The two electric push rods 215 are symmetrically fixed to the outer wall of the mixing vessel 101 by a bracket. The top of the output end of the electric push rod 215 is fixedly connected to the bottom of the lifting seat 202. The electric push rod 215 is used to realize the lifting operation of the lifting seat 202.

[0038] Two fixed guide rods 104 are symmetrically fixed on the top of the mixing vessel 101, and the lifting seat 202 is slidably sleeved with the two fixed guide rods 104.

[0039] In this embodiment, the stone paint production reactor has the following two operating modes:

[0040] The first mode is pure stirring mode. In this mode, the electric push rod 215 lifts the lifting seat 202 to a high position. The drag-reducing ball 209 on the top horizontal part of the scraper 207 is located at the highest point of the conical surface of the conical cylinder 212. The two scrapers 207 are retracted into the horizontal limiting groove 206 under the elastic force of the spring 208. That is, the scraper 207 does not contact the inner wall side of the mixing vessel 101. At the same time, the bottom of the rectangular stirring frame 205 does not contact the bottom of the inner wall of the mixing vessel 101.

[0041] In this case, the drive motor 201 is started, and the drive motor 201 drives the rotating shaft 203, stirring blades 204, and rectangular stirring frame 205 to rotate as a whole, which only plays the role of stirring materials and will not scrape the inner wall, side or bottom of the mixing vessel 101.

[0042] The second mode is the stirring and scraping mode. In this mode, the electric push rod 215 retracts, causing the lifting seat 202, drive motor 201, rotating shaft 203, stirring blade 204, and rectangular stirring frame 205 to move downward as a whole. The scraping component 207 moves downward simultaneously and is squeezed by the conical surface of the conical cylinder 212 through the drag-reducing ball 209. At this time, the scraping component 207 is subjected to a thrust, which causes the scraping component 207 to move horizontally along the trajectory of the horizontal limiting slide groove 206 and compress the spring 208 to further retract. Finally, the side of the scraping component 207 is in contact with the inner wall side of the stirring vessel 101. At the same time, the rectangular stirring frame 205 moves downward, causing the bottom of the rectangular stirring frame 205 to be in contact with the bottom of the inner wall of the stirring vessel 101.

[0043] At this time, the drive motor 201 is started. The drive motor 201 drives the rotating shaft 203, stirring blades 204, and rectangular stirring frame 205 to rotate as a whole. This not only stirs the material, but also the circumferentially running scraper 207 can scrape the inner side of the mixing vessel 101, and the bottom of the rectangular stirring frame 205 can scrape the bottom of the inner wall of the mixing vessel 101.

[0044] When producing real stone paint, the mixing and scraping mode can be selectively activated during material mixing and when unloading. This not only prevents the material from adhering to the inner wall of the mixing vessel 101 and ensures the material is fully mixed, but also prevents the scraping component 207 from being constantly in contact with the inner wall of the mixing vessel 101, which would cause severe wear. This allows the scraping effect of the device to remain stable for a long time.

[0045] Please refer to this carefully. Figures 1-4 The outer wall of the rotating shaft 203 at the contact position with the rotating sleeve 211 and the conical cylinder 212 is formed with a limiting protrusion, and the inner side of the rotating sleeve 211 and the conical cylinder 212 is formed with a vertical guide groove 213 for the limiting protrusion to slide vertically.

[0046] The inner side of the fixed sleeve 210 and the outer side of the rotating sleeve 211 are formed with annular grooves for the rolling of the limiting ball 214.

[0047] In this embodiment, the synchronous rotation of the rotating shaft 203, the rotating sleeve 211, and the conical cylinder 212 can be achieved through the cooperation of the limiting protrusion and the vertical guide groove 213. The fixed cylinder seat 210, the limiting ball 214, and the rotating sleeve 211 cooperate to provide support and limit the rotation of the rotating shaft 203, ensuring the stability of the vertical movement and rotation of the rotating shaft 203.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
