Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, in particular to a flux grinding machine. Background Art

[0002] During the flux production process, the prepared flux raw materials must be mixed uniformly in a certain proportion. The mixed flux raw materials are then placed in a grinding machine. The materials are ground by adjusting parameters such as the roller speed and gap. Finally, the ground flux is filtered to remove impurities and particles. This grinding process requires the use of a grinder, with a three-roller grinder being a common type of flux grinding equipment. This grinding process uses three rollers to repeatedly squeeze and shear the material, achieving the desired grinding effect. However, existing three-roller grinders often leave a large amount of residual material on the discharge plate after grinding.

[0003] To this end, Chinese patent publication CN220091555U discloses a three-roller mill that uses a scraper box to scrape away residual material from the discharge plate. However, the three rollers in the three-roller mill described in the aforementioned patent and prior art experience inconsistent force, leading to inconsistent wear on the surfaces of the three rollers, which in turn affects the subsequent grinding effect. Furthermore, the rollers only apply a squeezing force to the material, flattening the particles and preventing them from being fully ground. This results in inadequate grinding and low grinding efficiency. Summary of the Invention

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] like Figures 1 to 9 As shown, a flux grinding machine provided by an embodiment of the present invention includes a frame 100, a grinding assembly 200, a scraper 300, a switching mechanism 400, a distance control assembly and a control system.

[0039] The rack 100 is sequentially provided with a first position, a second position and a third position from the rear to the front;

[0040] The grinding assembly 200 includes three grinding rollers 210, the axes of which extend in the left-right direction. The three grinding rollers 210 are respectively installed at a first position, a second position, and a third position. The grinding rollers 210 are rotatably mounted on the frame 100. Each grinding roller 210 is connected to a drive assembly 110, which is used to drive the grinding roller 210 to rotate about its own axis.

[0041] The scraper 300 is tilted and arranged at the front side of the frame 100. The rear side of the scraper 300 abuts against the grinding roller 210 at the third position, and the rear end of the scraper 300 is higher than the front end.

[0042] The switching mechanism 400 is used to move the grinding roller 210 originally located at the first position to the second position, move the grinding roller 210 originally located at the second position to the third position, and move the grinding roller 210 originally located at the third position to the first position;

[0043] The distance adjustment component is used to adjust the distance between two adjacent grinding rollers 210;

[0044] The control system is used for the rotation speed of the grinding roller 210 .

[0045] When grinding the flux, the raw materials are mixed evenly according to the proportions. The mixed flux is then poured between the two grinding rollers 210 away from the scraper 300. The drive assembly 110 drives the corresponding grinding rollers 210 to rotate. During the rotation of the grinding rollers 210, the two grinding rollers 210 in the first and second positions rotate in opposite directions and at different speeds. The flux is subjected to friction and shear forces, and the diameter of the granular material decreases. The ground flux passes through the gap between the two grinding rollers 210 and adheres to the surface of the grinding rollers 210. As the grinding rollers 210 continue to rotate, the flux reaches between the two grinding rollers 210 in the second and third positions. The two grinding rollers 210 in the second and third positions rotate in opposite directions and at different speeds, grinding the flux a second time and adhering to the surface of the grinding rollers 210. As the grinding rollers 210 rotate, the fully ground flux reaches the contact point between the scraper 300 and the grinding rollers 210 and is scraped onto the surface of the scraper 300, completing the grinding. During the grinding process, the distance between the two grinding rollers 210 can be adjusted by the distance adjustment component, thereby adjusting the fineness of the flux.

[0046] After a period of grinding, the three grinding rollers 210 exhibit varying degrees of wear. The switching mechanism 400 causes the positions of the three grinding rollers 210 to change, shifting the grinding roller 210 originally in the first position to the second position, the grinding roller 210 originally in the second position to the third position, and the grinding roller 210 originally in the third position to the first position. The control system controls the drive assembly 110 as needed, thereby adjusting the rotational speed of the corresponding grinding roller 210. By providing a switching mechanism 400 to adjust the position of the grinding rollers 210, the present invention solves the problems of poor grinding performance and inconsistent wear on multiple rollers in the prior art, thereby extending the service life of the grinding machine.

[0047] In a further embodiment, the frame 100 is provided with a track connected end to end, and a movable plate 211 is provided at both ends of the axial direction of the grinding roller 210, and the movable plate 211 is installed in the track; the grinding roller 210 is rotatably connected to the movable plate 211;

[0048] The driving assembly 110 includes a driving motor 111, a driving wheel 112, and a driven wheel 113; the driving motor 111 is fixedly connected to the movable plate 211; the driving wheel 112 is synchronously rotated and mounted on the output shaft of the driving motor 111, and the driven wheel 113 can be movably mounted on the frame 100 in the left and right directions, and is sleeved on the rotating shaft of the grinding roller 210, and the rotating shaft of the grinding roller 210 is synchronously rotated and connected to the first end face gear 212; the driven wheel 113 is synchronously rotated and connected to the second end face gear 114 toward the side of the first end face gear 212; the first end face gear 212 is meshed with the second end face gear 114.

[0049] During grinding, the driving motor 111 drives the driving wheel 112 to rotate synchronously, and the driving wheel 112 drives the driven wheel 113 to rotate. When the driving wheel 112 rotates, the second end gear 114 drives the first end gear 212 to rotate synchronously, thereby driving the grinding roller 210 to rotate.

[0050] In a further embodiment, a switching plate 213 is slidably mounted on the rotating shaft of each grinding roller 210 , and the driven wheel 113 is rotatably mounted on the switching plate 213 ;

[0051] The switching assembly includes a chain 410, a fixed plate 420 and three sprockets 430; the fixed plate 420 is fixedly connected to the frame 100, and the chain 410 is connected end to end and fixedly connected to the outer periphery of the fixed plate 420; a sprocket 430 is rotatably installed on the rotating shaft of each grinding roller 210; the sprocket 430 is arranged on the side of the driven wheel 113 away from the first end face gear 212, and the three sprockets 430 are all engaged with the chain 410; the sprocket 430 is synchronously connected to the third end face gear 431 toward the side of the corresponding driven wheel 113 for synchronous rotation; the driven wheel 113 is synchronously connected to the fourth end face gear 115 toward the side of the third end face gear 431 for synchronous rotation, and the fourth end face gear 115 extends out of the switching plate 213; the switching plate 213 is connected to an adjustment assembly, which is used to adjust the distance between the switching plate 213 and the sprocket 430 under the instruction of the control system.

[0052] When grinding is required, the corresponding switching plate 213 is driven by the adjusting component to move toward the first end face gear 212. When the switching plate 213 moves, the driven wheel 113 moves synchronously, and the distance between the first end face gear 212 and the second end face gear 114 is reduced until the two are engaged. At this time, the driving motor 111 drives the active wheel 112 to rotate synchronously, and the active wheel 112 drives the driven wheel 113 to rotate synchronously, and the second end face gear 114 rotates synchronously with the driven wheel 113, and then drives the grinding roller 210 to rotate through the first end face gear 212 to grind the flux.

[0053] When the position of the grinding roller 210 needs to be changed, the switching plate 213 is driven by the adjustment component to move toward the sprocket 430. When the switching plate 213 moves, the driven wheel 113 moves synchronously, and the first end face gear 212 and the second end face gear 114 are disengaged; the distance between the third end face gear 431 and the fourth end face gear 115 is reduced until they are engaged. At this time, the driving motor 111 drives the sprocket 430 to rotate through the driving wheel 112, the driven wheel 113, the fourth end face gear 115 and the third end face gear 431 in sequence. Since the sprocket 430 is engaged with the chain 410, during the rotation of the sprocket 430 In the embodiment, the sprocket 430 moves along the trajectory of the chain 410. When the grinding roller 210 originally located at the first position reaches the second position, the control system controls the corresponding adjusting component to disengage the third end face gear 431 and the fourth end face gear 115; when the grinding roller 210 originally located at the second position reaches the third position, the control system controls the corresponding adjusting component to disengage the third end face gear 431 and the fourth end face gear 115; when the grinding roller 210 originally located at the third position reaches the first position, the control system controls the corresponding adjusting component to disengage the third end face gear 431 and the fourth end face gear 115.

[0054] In a further embodiment, the adjustment assembly includes a cylinder and an adjustment spring 214. The cylinder is mounted on the frame 100, with its other end connected to the switching plate 213. The ends of the adjustment spring 214 abut the movable plate 211 and the driven wheel 113, respectively. When grinding flux, the cylinder is activated, driving the switching plate 213 toward the movable plate 211 until the first face gear 212 and the second face gear 114 engage. As the switching plate 213 moves, the adjustment spring 214 compresses and accumulates force. To change the position of the grinding roller 210, the cylinder is activated, driving the switching plate 213 toward the sprocket 430. During this process, the adjustment spring 214 releases its force until the fourth face gear 115 and the third face gear 431 engage.

[0055] In a further embodiment, a moving assembly 120 is provided at the second position of the frame 100, and the moving assembly 120 is used to drive the grinding roller 210 located at the second position to move back and forth along the axial direction.

[0056] When grinding the flux paste, the three driving components 110 drive the three grinding rollers 210 to rotate respectively, and the moving component 120 drives the grinding roller 210 located at the second position to move back and forth along the axis. When the flux is located between two adjacent grinding rollers 210, it is not only squeezed by the two grinding rollers 210, but also subjected to shear force in the left and right directions, so that the flux is fully ground and the grinding efficiency of the flux is improved.

[0057] In a further embodiment, the moving assembly 120 includes a moving mounting frame 121, a moving motor 122, a moving spring 123, a first connecting rod 124 and a second connecting rod 125; the moving mounting frame 121 can be movably installed on the frame 100 in the left and right directions, and the slide rail at the second position is set on the moving mounting frame 121; the moving spring 123 extends in the left and right directions, and its two ends are respectively abutted against the frame 100 and the moving mounting frame 121; the moving motor 122 is installed on the frame 100, one end of the first connecting rod 124 is synchronously rotatably connected to the output shaft of the moving motor 122, and the other end is hinged to the second connecting rod 125, and the end of the second connecting rod 125 away from the first connecting rod 124 is hinged to the moving mounting frame 121.

[0058] During the grinding process, the three driving components 110 drive the three grinding rollers 210 to rotate respectively. After the mobile motor 122 is started, it drives the first connecting rod 124 to rotate. During the rotation of the first connecting rod 124, the second connecting rod 125 drives the mobile mounting frame 121 to move left and right, and then drives the grinding roller 210 located in the second position to move left and right. During the movement of the mobile mounting frame 121, the mobile spring 123 is compressed and released back and forth.

[0059] In a further embodiment, baffles 220 are provided on both sides of the grinding roller 210 in the axial direction. The baffles 220 are vertically arranged and extend in the front-to-back direction. The baffles 220 are detachably fixed to the frame 100 and clamped above the grinding roller 210. This prevents the flux from leaking from both sides of the grinding roller 210 during the grinding process.

[0060] In a further embodiment, the scraper 300 is wavy. During the grinding process, the grinding roller 210 closest to the scraper 300 abuts the scraper 300. As the grinding roller 210 rotates, the flux on the grinding roller 210 is scraped onto the upper surface of the scraper 300. Due to the high viscosity of the material, the material that reaches the scraper 300 first is pushed by the material that arrives later, causing it to flow. Due to the wavy shape of the scraper 300, the material that reaches the scraper 300 is separated and stored in recessed positions within the scraper 300. Material in one recessed position is not pulled by material in adjacent recesses, thus eliminating the problem of material flow being slowed down by the pull of adjacent material, which can lead to accumulation at the end of the scraper 300 where it abuts the roller.

[0061] In a further embodiment, the scraper 300 is connected to a swinging assembly 310, which is used to drive the scraper 300 to move axially along the grinding roller 210. When the scraper 300 is deformed, a gap appears between the scraper 300 and the roller. As the roller rotates, the undeformed portion of the scraper 300 can smoothly scrape the flux from the roller, while the scraper 300 at the deformed position has a poor scraping effect or may even be unable to scrape the flux from the roller. However, since the scraper 300 is wavy, although the grooves at the deformed position cannot scrape the material, the adjacent raised positions can scrape the flux from both sides during the process of the scraper 300 being driven left and right by the swinging assembly 310, thereby solving the problem of poor scraping effect when the scraper 300 is deformed.

[0062] In a further embodiment, the swing assembly 310 includes a swing bracket 311, a rotating plate 312, a swing motor 313, and a swing cam 314; the swing bracket 311 is arranged at the front end of the frame 100; the rotating plate 312 is rotatably mounted on the swing bracket 311, and the rotating plate 312 is horizontally connected to the guide rod 316; the scraper 300 is fixedly connected to the moving block 301, and the moving block 301 is slidably mounted on the guide rod 316; the swing motor 313 is fixedly connected to the rotating plate 312, and the output end of the swing motor 313 is synchronously rotated and connected to the swing cam 314; a swing spring 315 is provided on the guide rod 316, and the two ends of the swing spring 315 are respectively abutted against the moving block 301 and the swing bracket 311, and the swing spring 315 makes the moving block 301 abut against the swing cam 314.

[0063] The swing motor 313 drives the swing cam 314 to rotate. In the process of the swing cam 314 and the moving block 301 contacting from the near point to the far point, the moving block 301 is pushed away from the axis of the swing cam 314. At the same time, the swing spring 315 accumulates force. In the process of the swing cam 314 and the moving block 301 contacting from the far point to the near point, the swing spring 315 releases the elastic force, pushing the moving block 301 to approach the axis of the swing cam 314, and repeating the cycle.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
