Technical Field

[0001] The utility model relates to the technical field of welding rod production equipment, in particular to a powder mixing device. Background Art

[0002] Welding rod coatings are a layer of fine-grained materials with varying physical and chemical properties that are uniformly bonded and coated onto the surface of the welding core. They play a crucial role in the welding process, ensuring that the weld metal possesses the required chemical composition and mechanical properties, and ensuring that the welding rod exhibits good welding process performance. Therefore, pressure-coating the coating is an essential step in welding rod production. The coating is composed of various minerals, ferroalloy organics, and chemical products (such as water glass). The composition of welding rod coatings is quite complex, with as many as seven or eight ingredients typically found in a single coating formulation. Therefore, prior to pressure-coating, the coating components must be mixed and stirred according to the formula.

The device comprises a base, a mixing barrel mounted on the base, a drive shaft disposed within the mixing barrel and provided with an annular bevel groove, multiple connecting rods mounted within the annular bevel groove, a mixing plate with a variable area mounted at the lower ends of the connecting rods, and an adjustment assembly mounted on the mixing plate. Driven by a motor, the drive shaft rotates, driving the mixing plate, mounted within the annular bevel groove, to alternately move up and down, stirring the material.

[0004] The production of the medicine coating requires that the raw materials have a certain viscosity and humidity when mixed. However, during the stirring process of the above-mentioned prior art, some of the raw materials are easily adhered to the barrel wall of the mixing barrel, resulting in uneven mixing. Utility Model Content

[0005] The purpose of the utility model is to overcome the above technical deficiencies and propose a medicine powder mixing device to solve the technical problem in the prior art that part of the raw materials are easily adhered to the barrel wall of the mixing barrel during the stirring process, resulting in uneven mixing.

[0006] In order to achieve the above technical purpose, the present invention adopts the following technical solutions:

[0008] Mixing barrel;

[0009] A stirring assembly, the stirring assembly being arranged in the stirring barrel;

[0010] A scraper, the scraper is arranged in an annular shape and adapted to the inner diameter of the mixing barrel, and the scraper is movably mounted on the inner wall of the mixing barrel along a vertical direction; and

[0011] A driving assembly is connected to the scraper to drive the scraper to move.

[0012] In one embodiment, the upper side of the scraper is gradually tilted downward toward the middle of the mixing barrel, and the lower side of the scraper is gradually tilted upward toward the middle of the mixing barrel.

[0013] In one embodiment, an annular groove is provided in the middle of one side of the scraper facing the side wall of the mixing barrel.

[0014] In one embodiment, the driving assembly includes a magnetic part and a driving component. The magnetic part is movably installed on the outer periphery of the mixing barrel along the vertical direction. The magnetic part is magnetically engaged with the scraper. The driving component is connected to the magnetic part to drive the magnetic part to move.

[0015] In one embodiment, the driving component includes a mounting seat, a screw and a driving motor. The mounting seat is movably mounted on the outer periphery of the mixing barrel in a vertical direction. The mounting seat is provided with a threaded hole. The magnetic member is mounted on the mounting seat. The screw is rotatably mounted on the outer periphery of the mixing barrel along an axis in a vertical direction.

At this time, the driving component is started, and the scraper is driven to reciprocate in the vertical direction by the driving component. Since the scraper is adapted to the inner diameter of the stirring barrel, the scraper is close to the inner wall of the stirring barrel, thereby scraping off the material adhered to the side wall. The scraped material falls under the action of its own gravity, thereby preventing the material from adhering to the scraper. Such a setting can quickly clean the material on the side wall to avoid uneven mixing.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] In order to solve the technical problem in the prior art that some raw materials are easily adhered to the barrel wall of the mixing barrel during the stirring process, resulting in uneven mixing, the utility model provides a powder mixing device that can quickly clean the materials on the side wall to avoid uneven mixing.

[0031] See also Figure 1 , Figure 1 This is a schematic structural diagram of a medicine powder mixing device in one embodiment of the present invention.

[0032] The utility model provides a medicine powder mixing device, comprising a stirring barrel 1, a stirring component 2, a scraper 3 and a driving component 4; the stirring component 2 is arranged in the stirring barrel 1; the scraper 3 is arranged in an annular shape and is adapted to the inner diameter of the stirring barrel 1, and the scraper 3 is movably installed on the inner wall of the stirring barrel 1 along the vertical direction; the driving component 4 is connected to the scraper 3 to drive the scraper 3 to move.

[0033] In this embodiment, the stirring assembly 2 is arranged in the stirring barrel 1, the scraper 3 is annularly arranged and adapted to the inner diameter of the stirring barrel 1, the scraper 3 is movably installed on the inner wall of the stirring barrel 1 in the vertical direction, and the driving assembly 4 is connected to the scraper 3 to drive the scraper 3 to move. When in use, the material is loaded into the stirring barrel 1, and then the stirring assembly 2 is started to stir the material. Since the material has a certain humidity and viscosity, part of the material adheres to the side wall of the stirring barrel 1. At this time, the driving assembly 4 is started, and the scraper 3 is driven by the driving assembly 4 to reciprocate in the vertical direction. Since the scraper 3 is adapted to the inner diameter of the stirring barrel 1, the scraper 3 is close to the inner wall of the stirring barrel 1, thereby scraping off the material adhered to the side wall. The scraped material falls under the action of its own gravity, thereby preventing the material from adhering to the scraper 3. Such a setting can quickly clean the material on the side wall to avoid uneven mixing.

[0034] In one embodiment, see Figure 3 The upper side of the scraper 3 is gradually tilted downward toward the middle of the mixing barrel 1 , and the lower side of the scraper 3 is gradually tilted upward toward the middle of the mixing barrel 1 .

[0035] In this embodiment, since the scraper 3 moves in the vertical direction, when scraping the material from bottom to top, the upper side of the scraper 3 contacts the material. In order to smoothly scrape the material and avoid the accumulation of material on the upper side, the upper side of the scraper 3 is gradually tilted downward toward the middle of the mixing barrel 1. When scraping the material from top to bottom, the lower side of the scraper 3 contacts the material. Therefore, the lower side of the scraper 3 is gradually tilted upward toward the middle of the mixing barrel 1. Setting the upper and lower sides of the scraper 3 as inclined surfaces is beneficial for the scraper 3 to scrape the material.

[0036] In one embodiment, see Figure 3 The scraper 3 is provided with an annular groove in the middle of one side facing the side wall of the mixing barrel 1.

[0037] In this embodiment, the diameter of the scraper 3 is adapted to the inner diameter of the mixing barrel 1, and the scraper 3 abuts against the side wall of the mixing barrel 1. In order to reduce the resistance of the scraper 3 to the movement in the vertical direction, the scraper 3 is provided with an annular groove in the middle of one side facing the side wall of the mixing barrel 1. Such a configuration can reduce the contact area between the scraper 3 and the side wall of the mixing barrel 1, thereby reducing the friction between the scraper 3 and the side wall of the mixing barrel 1.

[0038] Furthermore, in order to further improve the smoothness of the movement of the scraper 3, a plurality of balls 31 are provided in the annular groove, and the balls 31 abut against the side walls of the mixing barrel 1. A stopping protrusion is provided in the annular groove, and the stopping protrusion is located on the downward side walls of the annular groove and is arranged in an annular shape. The stopping protrusion can limit the ball 31 to prevent the ball 31 from detaching from the notch of the annular groove.

[0039] Furthermore, due to the provision of the stopping protrusion, in order to facilitate the installation and removal of the ball 31, a mounting hole connected to the annular groove is provided on the inner side of the scraper 3, and the diameter of the mounting hole is adapted to the ball 31. The ball 31 is installed in the annular groove through the mounting hole. The powder mixing device also includes a sealing member, which is detachably provided in the mounting hole so that when the ball 31 is installed in the buffer groove, the sealing member blocks the mounting hole.

[0040] In one embodiment, see Figures 2 to 4 The driving assembly 4 includes a magnetic part 41 and a driving component. The magnetic part 41 is movably installed on the outer periphery of the mixing barrel 1 along the vertical direction. The magnetic part 41 is magnetically engaged with the scraper 3. The driving component is connected to the magnetic part 41 to drive the magnetic part 41 to move.

[0041] In this embodiment, since the scraper 3 moves in the mixing barrel 1, and the mixing barrel 1 is filled with powder material during operation, the mixing barrel 1 is also provided with a stirring assembly 2, resulting in a small installation environment and installation space in the mixing barrel 1. The driving assembly 4 is not suitable to be arranged in the mixing barrel 1. Therefore, the scraper 3 is made of magnetic material, and the magnetic member 41 is movably installed on the outer periphery of the mixing barrel 1 along the vertical direction and is arranged corresponding to the scraper 3. The magnetic member 41 can be magnetically matched with the scraper 3 so that the magnetic member 41 can drive the scraper 3 to move in the vertical direction. The driving component is also arranged outside the mixing barrel 1 and can drive the magnetic member 41 to move. The magnetic member 41 is magnetically matched with the scraper 3, and then the driving component drives the magnetic member 41 to move, thereby achieving the purpose of driving the scraper 3 to move. The driving assembly 4 is arranged outside the mixing barrel 1. On the one hand, it can avoid occupying the space in the mixing barrel 1, and on the other hand, it can prevent the powder material from adhering to the driving assembly 4.

[0042] It should be noted that the mixing barrel 1 is made of non-magnetic material, which has no magnetism and magnetic isolation effect, thereby preventing the mixing barrel 1 from interfering with the scraper 3 and the magnetic member 41 .

[0043] In one embodiment, see Figures 2 to 4 The driving component includes a mounting seat 42, a screw rod 43 and a driving motor 44. The mounting seat 42 is movably mounted on the outer periphery of the mixing barrel 1 along the vertical direction. The mounting seat 42 is provided with a threaded hole. The magnetic member 41 is mounted on the mounting seat 42. The screw rod 43 is rotatably mounted on the outer periphery of the mixing barrel 1 along the axis in the vertical direction. The screw rod 43 is threadedly engaged with the mounting seat 42. The driving motor 44 is connected to one end of the screw rod 43.

[0044] In this embodiment, the mounting seat 42 is arranged in a ring shape, and the inner side of the mounting seat 42 is provided with a mounting groove adapted to the magnetic member 41, and the magnetic member 41 is arranged in the mounting groove. A plurality of guide rods 45 are arranged at intervals on the outer periphery of the mixing barrel 1, and the guide rods 45 are extended in the vertical direction. The mounting seat 42 is provided with a plurality of guide sleeves 46, and the plurality of guide sleeves 46 correspond one-to-one to the plurality of guide rods 45. Each guide sleeve 46 is slidably installed in the guide rod 45, so that the mounting seat 42 can move in the vertical direction. The upper and lower ends of the screw rod 43 are rotatably installed on the outside of the mixing barrel 1 and are threadedly matched with the mounting seat 42. The driving motor 44 is provided on the upper side of the mixing barrel 1, and the main shaft of the driving motor 44 is fixedly connected to the screw rod 43, so that the screw rod 43 can be driven to rotate by the driving motor 44, thereby driving the mounting seat 42 to move in the vertical direction.

[0045] In one embodiment, see Figures 1 to 2 The powder mixing device further includes a mounting barrel 5, which is sleeved around the outer periphery of the mixing barrel 1 and spaced apart from the mixing barrel 1. A mounting cavity is formed between the mounting barrel 5 and the mixing barrel 1, and the magnetic member 41 and the driving component are both located within the mounting cavity. The mounting barrel 5 provides a certain degree of protection, thereby preventing damage to the magnetic member 41 and the driving component.

[0046] In one embodiment, see Figure 3 There is a gap between the magnetic member 41 and the outer wall of the mixing barrel 1.

[0047] In this embodiment, the magnetic member 41 can move in the vertical direction. In order to reduce the movement resistance of the magnetic member 41, a gap is provided between the magnetic member 41 and the outer wall of the mixing barrel 1. Such a setting can prevent the magnetic member 41 from contacting the mixing barrel 1.

[0048] In one embodiment, a magnetic isolation member is provided on the inner side wall of the mounting tube 5 .

[0049] In this embodiment, in order to prevent the magnetic member 41 from interfering with the outside world, a magnetic isolation member is provided on the inner side wall of the installation tube 5 , and the magnetic isolation member can shield the magnetic member 41 .

[0050] In one embodiment, the magnetic member 41 is arranged in a ring shape.

[0051] In this embodiment, the scraper 3 is arranged in a ring shape. In order to increase the contact area between the magnetic member 41 and the scraper 3 and improve the magnetic attraction between the two, the magnetic member 41 is also arranged in a ring shape, and its thickness is slightly greater than the thickness of the scraper 3.

[0052] In one embodiment, the medicine powder mixing device further includes a temperature and humidity sensor, which is disposed in the mixing barrel 1 and is used to detect the temperature and humidity of the material in the mixing barrel 1 .

[0053] In this embodiment, the stirring assembly 2 includes a stirring shaft 21, a stirring paddle 22 and a stirring motor 23. The stirring shaft 21 is installed in the stirring barrel 1 in a vertical direction, and its lower end extends into the stirring barrel 1. The stirring paddle 22 is fixedly installed at the lower end of the stirring shaft 21. The stirring motor 23 is installed on the upper side of the stirring barrel 1. The main shaft of the stirring motor 23 is connected to the upper end of the stirring shaft 21 to drive the stirring shaft 21 to rotate through the stirring motor 23.

[0054] In order to better understand the present invention, the following Figures 1 to 4The technical solution of the utility model is described in detail:

[0055] During specific use, the material is loaded into the mixing barrel 1, and then the stirring component 2 is started to stir the material. Since the material has a certain humidity and viscosity, part of the material adheres to the side wall of the mixing barrel 1. At this time, the drive motor 44 is started, and the drive motor 44 drives the screw rod 43 to rotate, thereby driving the mounting seat 42 and the magnetic part 41 to move. The magnetic part 41 is magnetically engaged with the scraper 3, and then drives the scraper 3 to reciprocate in the vertical direction. The material adhered to the side wall is scraped off through the upper and lower sides of the scraper 3. The scraped material falls under the action of its own gravity, which can quickly clean the material on the side wall and avoid uneven mixing.

[0056] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
