Description

Technical Field

[0001] This utility model relates to the field of drum grinding machine technology, specifically to an adjustment device for a drum grinding machine. Background Technology

[0002] As is well known, in industries such as metal processing, electronics manufacturing, and chemical materials, drum grinding mills are core processing equipment. They achieve functions such as deburring, crushing, and polishing by rotating the drum and driving the grinding media to interact with the materials. Traditional single-drum grinding mills are widely used in small and medium-sized enterprises due to their simple structure and low cost. They can process large quantities of materials at a time. Double-drum grinding mills, on the other hand, utilize the squeezing and shearing forces between the drums to play an important role in precision processing fields such as lithium battery slurry homogenization and optical glass polishing.

[0003] The two rollers on existing drum grinding machines generally adopt a fixed structure, meaning that the initial distance between the two rollers is determined during the equipment manufacturing process and is difficult to adjust later. Although some equipment is equipped with adjustment functions, it requires complex operations such as disassembling bolts and adding or removing shims, which is not only time-consuming and labor-intensive, but also has low adjustment accuracy, making it difficult to meet the fine grinding needs of different materials. Utility Model Content

[0004] Technical problems to be solved In order to overcome the problem that the adjustment device of the existing drum grinder is inconvenient to adjust the spacing, this utility model provides an adjustment device for the drum grinder that has a convenient spacing adjustment effect.

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: an adjustment device for a drum grinder, comprising a base, multiple sets of movable plates, the movable plates being slidably disposed on one side of the base, two sets of drum bodies, the two sets of drum bodies being rotatably disposed between the multiple sets of movable plates, and two sets of adjustment components. Each adjustment component includes a horizontal plate disposed on one side of the base. Two sets of moving columns and two sets of push plates are slidably disposed inside the horizontal plate. One end of each moving column is fixedly disposed to one side of the movable plate. The movement of the moving column will cause the movable plate to shift, and the shift of the movable plate will cause the drum body to shift, thereby adjusting the distance between the two sets of drum bodies. A protrusion, which is semi-elliptical, is provided on the side of the push plate away from the moving column. Two sets of mounting shafts are provided on one side of the horizontal plate. A swing plate is rotatably disposed on the outer side of each mounting shaft, and the swing plate is used to push the push plate laterally. A half-gear is provided on one side of the swing plate, and a drive component is provided. The drive component is disposed inside the base, and one side of the drive component meshes with the half-gear.

[0006] Preferably, two sets of support plates are provided on one side of the horizontal plate, and the side of the support plate away from the horizontal plate is fixedly installed on one side of the base.

[0007] Furthermore, a spring is provided on one side of the movable column, and the end of the spring away from the movable column is fixedly installed inside the horizontal plate.

[0008] Furthermore, two sets of blocking plates are provided on the outer side of the push plate, and the two sets of blocking plates are located on both sides of the horizontal plate.

[0009] In a further embodiment, the swing plate is slidably disposed inside the horizontal plate on the side away from the half gear, a central shaft is disposed on the side of the swing plate away from the half gear, and a pulley is rotatably disposed on the outer side of the central shaft, with the outer side of the pulley contacting one side of the protrusion.

[0016] 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.

[0017] See Figures 1-8 An adjustment device for a drum grinder includes a base 1, a guide plate 7 welded to the top of the base 1, the guide plate 7 being inclined, four sets of movable plates 4 slidably connected to the top of the base 1, and the four sets of movable plates 4 being located on both sides of the guide plate 7 respectively. The front two sets of movable plates 4 are each equipped with a rotary motor 5, the output end of the rotary motor 5 being keyed to a drum body 6. When the rotary motor 5 is turned on, the output end of the rotary motor 5 will drive the drum body 6 to rotate and grind the material, and the two sets of drum bodies 6 are slidably connected between the four sets of movable plates 4. Two sets of adjustment components 2 are fixedly installed on the top of the base 1, and two sets of drive components 3 are installed inside the base 1, with one side of the drive component 3 meshing with one side of the adjustment component 2.

[0018] First, refer to Figures 1 to 5In this embodiment, the adjusting component 2 includes a horizontal plate 201. Two sets of support plates 205 are welded to the bottom of the horizontal plate 201. The bottom of the support plates 205 is welded to the top of the base 1. A sliding groove 204 is provided inside the horizontal plate 201. Two sets of moving columns 203 and two sets of push plates 207 are slidably connected inside the sliding groove 204. One end of the moving column 203 is welded to the movable plate 4. A protrusion 208 is welded to the side of the push plate 207 away from the moving column 203. The protrusion 208 is semi-elliptical. Two sets of mounting shafts 211 are welded to the bottom of the horizontal plate 201. A swing plate 212 is rotatably connected to the outside of the mounting shaft 211. A half gear 210 is fixedly connected to the outside of the swing plate 212. The half gear 210 meshes with one side of the driving component 3. A central shaft 213 is welded to the top of the swing plate 212. A pulley 214 is rotatably connected to the outside of the central shaft 213. The outside of the pulley 214 contacts one side of the protrusion 208.

[0019] Specifically, in order to maintain the balance of the moving column 203, a limiting rod 206 is welded to the rear side of the horizontal plate 201. The moving column 203 is slidably connected to the outside of the limiting rod 206. Thus, on the one hand, the limiting rod 206 maintains the balance of the moving column 203 during movement, preventing the moving column 203 from becoming unbalanced and swaying during movement, and ensuring the normal displacement of the moving column 203. On the other hand, the limiting rod 206 restricts the direction of the moving column 203, preventing the device from failing due to misalignment of the moving column 203, and ensuring the normal use of the device.

[0020] Meanwhile, in order to enable the moving column 203 to move back quickly, a spring 202 is fixedly connected to one side of the moving column 203, and the end of the spring 202 away from the moving column 203 is fixedly connected to the inner wall of the slide groove 204. Thus, when the moving column 203 is pushed, the spring 202 will be squeezed by the moving column 203, and when the moving column 203 is no longer pushed, the spring 202 will bounce the moving column 203 back quickly.

[0021] Specifically, in order to prevent the push plate 207 from detaching from the horizontal plate 201, two sets of baffle plates 209 are welded on the outside of the push plate 207, and the two sets of baffle plates 209 are located at the top and bottom of the horizontal plate 201 respectively. Thus, the movement of the push plate 207 can be restricted by the baffle plates 209, and the push plate 207 can be prevented from detaching from the horizontal plate 201.

[0022] When the half gear 210 is pushed, the half gear 210 will drive the swing plate 212 to swing around the mounting shaft 211. At this time, one side of the swing plate 212 will drive the pulley 214 to swing by driving the central shaft 213 and push the protrusion 208 to move laterally. The lateral movement of the protrusion 208 will drive the push plate 207 to move. The movement of the push plate 207 will drive the movable plate 4 to move by pushing the moving column 203. The movement of the movable plate 4 will drive the rotating motor 5 and the roller body 6 to move laterally. At this time, the two sets of roller bodies 6 will move in opposite directions, thereby adjusting the distance between the two sets of roller bodies 6.

[0023] Finally, see Figure 1 , Figure 6 and Figure 7 In this embodiment, the drive assembly 3 includes a rotary motor 301, which is a bidirectional motor whose output end can rotate forward or backward. The rotary motor 301 is located inside the base 1. The output end of the rotary motor 301 is key-connected to a threaded tube 304. A sleeve 302 is screwed onto the outer side of the threaded tube 304. A threaded hole is opened inside the sleeve 302, and the thread on the inner wall of the threaded hole is compatible with the thread on the outer side of the threaded tube 304. When the threaded tube 304 rotates, it will drive the sleeve 302 to move linearly. A rack 303 is provided on both sides of the sleeve 302. The rack 303 meshes with the half gear 210. After the rotary motor 301 is turned on, the output end of the rotary motor 301 will drive the threaded tube 304 to rotate. The rotation of the threaded tube 304 will drive the sleeve 302 to move linearly. The movement of the sleeve 302 will drive the rack 303 to move. The movement of the rack 303 will drive the half gear 210 to rotate.

[0024] The adjustment device of this drum mill, through the cooperation between the push plate 207 and the moving column 203, will drive the movable plate 4 to move by pushing the moving column 203 when the push plate 207 moves laterally. The movement of the movable plate 4 will change the position of the drum body 6, thereby conveniently adjusting the gap between the two sets of drum bodies 6. This allows the device to flexibly adjust the gap between the drum bodies 6 according to the characteristics and fineness requirements of different materials, avoid material loss, and increase the versatility of the device.

[0025] Working principle: When using the adjusting device of this drum grinder, first place the adjusting device of the drum grinder in the desired position, then adjust the distance between the two sets of drum bodies 6, and turn on the two sets of rotary motors 301. The output end of the rotary motor 301 drives the threaded tube 304 to rotate. The rotation of the threaded tube 304 will drive the sleeve 302 to move linearly. The movement of the sleeve 302 will drive the rack 303 to move. The movement of the rack 303 will drive the half gear 210 to rotate. When the half gear 210 is driven, the half gear 210 will drive the swing plate 212 to swing around the mounting shaft 211 as the axis. At this time, the swing plate 212 swings. One side of the movable plate 212 will drive the pulley 214 to swing by driving the central shaft 213 and push the protrusion 208 to move laterally. The lateral movement of the protrusion 208 will drive the push plate 207 to move. The movement of the push plate 207 will drive the movable plate 4 to move by pushing the movable column 203. The movement of the movable plate 4 will drive the rotating motor 5 and the roller body 6 to move laterally. At this time, the two sets of roller bodies 6 will move in opposite directions, thereby adjusting the distance between the two sets of roller bodies 6. This allows the device to flexibly adjust the gap between the roller bodies 6 according to the characteristics and fineness requirements of different materials, avoiding material loss and increasing the versatility of the device.
