Description

Technical Field

[0001] The utility model relates to the technical field of ball bead screening machines, specifically a ball bead screening machine. Background Technique

[0002] Ball beads can refer to various beads or spheres with spherical or quasi-spherical appearances. During the production of ball beads, a ball bead screening machine can be used to precisely screen the ball beads to meet the strict requirements of different industries and fields for indicators such as the size and quality of the ball beads. The ball bead screening machine is an important material screening device and plays an important role in multiple industries, and it can be widely used in industries such as the chemical industry and the pharmaceutical industry.

[0003] The ball bead screening machine uses a set of parallel roller shafts. The roller shafts are rotated by the drive of a motor, and then the ball beads placed on the roller shafts are driven to move, thereby realizing the screening of the ball beads. Under the background of the rapid development of industrial automation and manufacturing, as a key device, the performance and efficiency of the ball bead screening machine directly affect the overall efficiency of the production line.

[0004] Currently, when using a ball bead screening machine, it is necessary to first rotate the appropriate screening machine according to the size of the ball beads, then check and power on the screening machine, and then the ball beads can be placed on the screening machine. Screening is achieved through the change in the distance between a set of roller shafts from small to large, and the ball beads after screening need to be stored separately.

[0005] However, since the distance between the roller shafts in the existing screening machine is fixed and cannot be adjusted according to the actual screening size of the ball beads, it is necessary to replace the equipment according to different requirements, thereby increasing the screening cost and reducing the work efficiency. Content of the Utility Model

[0006] Based on this, the purpose of the present utility model is to provide a ball bead screening machine to solve the technical problem that since the distance between the roller shafts in the existing screening machine is fixed and cannot be adjusted according to the actual screening size of the ball beads, it is necessary to replace the equipment according to different requirements, thereby increasing the screening cost and reducing the work efficiency.

[0007] To achieve the above object, the present utility model provides the following technical solutions: a ball bead screening machine, comprising a housing, the bottom of the housing is respectively hinged with a first support rod and a second support rod, a group of roller shafts are rotatably connected in the housing, one end of each roller shaft is movable in a corresponding hole, each hole is rotatably connected with a bearing through a rotating shaft, each bearing is installed on the outer surface of the corresponding roller shaft, a gear is provided on the outer surface of one end of each roller shaft close to the bearing, and the tooth blocks of the gear are of a planar structure, a group of grooves are provided at one end of the housing away from the gear, each groove is slidably connected with a convex block that fits the groove, one side of each convex block is slidably connected with a connecting member, and the other side of the connecting member is hinged to one end of the corresponding roller shaft, a fixed block is fixedly connected to one side of the housing close to the convex block, a clamping block is slidably connected in the fixed block, and connecting rods are respectively hinged between the two ends of the clamping block and the corresponding convex block.

[0008] By adopting the above technical solution, the clamping block slides in the fixed block, and through the transmission of the connecting rod, the convex block can be driven to move in the groove. Since one end of a group of roller shafts is rotatably connected to the housing through a rotating shaft and a bearing, when the convex block moves, the other ends of this group of roller shafts will move synchronously, thereby changing the relative distance between the roller shafts. The distance between the roller shafts from the end close to the gear to the end close to the convex block will gradually increase or decrease. And because the gear is set to be of a planar structure, the meshing degree between them can remain relatively stable during the movement of the roller shafts and will not be affected by the change of the position of the roller shafts. The screening machine can have high flexibility and adjustability, can be adjusted according to the screening size requirements of different ball beads, without replacing the whole device, which is convenient for improving work efficiency and reducing screening costs.

[0009] The present utility model is further provided that the output end of a motor is connected to one end of one of the roller shafts close to the gear, the motor is installed in a noise reduction box, a support block is fixedly connected to one side of the housing, and the noise reduction box slides on the top of the support block.

[0010] By adopting the above technical solution, the noise generated during the operation of the motor can be effectively reduced by the noise reduction box, and the position of the motor can be flexibly adjusted due to the sliding connection between the noise reduction box and the support block, ensuring that it does not affect the driving of the roller shafts by the motor, which is convenient for better use of the screening machine.

[0011] The present utility model is further provided that an arc-shaped slider is fixedly connected to the bottom of the noise reduction box, and an arc-shaped chute that fits the arc-shaped slider is provided on the top of the support block, and the arc-shaped slider rotates concentrically with the rotating shaft.

[0012] By adopting the above technical solution, the arc-shaped chute and the arc-shaped slider are provided, enabling the muffler to drive the motor to slide on the top of the support plate. Since the arc-shaped slider rotates concentrically with the rotating shaft, the motor can move synchronously with the roller shaft, thus avoiding affecting the driving of the roller shaft and ensuring the stability and continuity of the screening process.

[0013] The present utility model is further provided that a conveying device is installed at one end of the housing close to the second support rod. A funnel is provided at one end of a set of roller shafts close to the conveying device, and the outlet of the conveying device and the funnel are connected to the housing through a bracket.

[0014] By adopting the above technical solution, the conveying device can continuously convey the to-be-screened beads into the funnel, and then the funnel ensures the smooth transition of the beads from the conveying device to the roller shaft area for screening, reducing the decrease in screening efficiency caused by poor material flow or accumulation, and facilitating the improvement of the screening work efficiency.

[0015] The present utility model is further provided that a plurality of limiting grooves are provided at the bottom inside the housing. Each limiting groove is slidably connected with a limiting block that fits the limiting groove. The top of each limiting block is fixedly connected with a collection box, and the collection box is located below a set of roller shafts.

[0016] By adopting the above technical solution, the limiting block can limit the position of the collection box, preventing it from shifting inside the housing and affecting the collection of the screened beads. Moreover, the connection mode of the collection box with the limiting block through the limiting groove makes the disassembly and assembly simple and fast. At the same time, since the collection box is located below the roller shafts, the screened beads can directly fall into the collection box, facilitating the improvement of work efficiency.

[0017] The present utility model is further provided that a clamping groove is provided inside the fixed block. A clamping block that fits the clamping groove is slidably connected inside the clamping groove. A threaded rod that fits the clamping block is rotatably connected inside the clamping groove, and the clamping block moves on the outer surface of the threaded rod. The top of the threaded rod movably penetrates the top of the fixed block and extends to the outside.

[0018] By adopting the above technical solution, rotating the threaded rod can drive the clamping block to move inside the clamping groove, thereby realizing the adjustment of the position of the clamping block. Moreover, the clamping groove can limit the clamping block, ensuring that the clamping block can only move along a predetermined path, thus realizing the adjustment of the position of the convex block.

[0019] The present utility model is further provided that the second support rod includes a sleeve and a movable rod. The movable rod is threadedly connected inside the sleeve, and the top of the movable rod is hinged to the bottom of the housing.

[0020] By adopting the above technical solution, the rotating movable rod can easily adjust its position within the sleeve, thereby changing the overall height of the second support rod. Then, the inclination angle of the housing can be adjusted according to actual needs to make it present an inclined plane structure, which helps to better screen the ball beads.

[0021] In summary, the present utility model mainly has the following beneficial effects:

[0022] In the present utility model, by driving the sliding of the clamping block, the convex block moves within the groove through the transmission of the connecting rod. And since one end of a set of roller shafts is rotationally connected to the housing through a rotating shaft and a bearing, when the convex block moves, it will drive the other end of this set of roller shafts to move synchronously, thereby changing the relative distance between the roller shafts. From the end close to the gear to the end close to the convex block, the distance between the roller shafts will gradually become larger or smaller. And since the gear is set as a planar structure, the meshing degree between them can remain relatively stable when the roller shafts move and will not be affected by the change of the roller shaft position. This enables the screening machine to have high flexibility and adjustability, and can be adjusted according to the screening size requirements of different ball beads without replacing the entire device, which helps to improve work efficiency and reduce screening costs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0030] Next, the embodiments of the present utility model will be described according to its overall structure.

[0031] A ball bead screening machine, as Figures 1-5 shown, includes a housing 1. A first support rod 2 and a second support rod 3 are respectively hinged to the bottom of the housing 1, which can support the housing 1. A set of roller shafts 4 are rotatably connected in the housing 1. The second support rod 3 includes a sleeve 301 and a movable rod 302. The movable rod 302 is threadedly connected in the sleeve 301, and the top of the movable rod 302 is hinged to the bottom of the housing 1. Therefore, the position of the movable rod 302 in the sleeve 301 can be easily adjusted by rotating the movable rod 302, so that the height of the second support rod 3 can be changed, and then the inclination angle of the housing 1 can be adjusted according to actual needs to make it present an inclined surface structure, which is convenient for better screening of ball beads.

[0032] Subsequently, a set of holes 5 are provided at one end of the housing 1 close to the second support rod 3. One end of each roller 4 is movable within the corresponding hole 5. A bearing 6 is rotatably connected to each hole 5 through a rotating shaft 7, and each bearing 6 is installed on the outer surface of the corresponding roller 4. This enables each roller 4 and the bearing 6 to move within the hole 5 through the corresponding rotating shaft 7 without affecting the rotation of the roller 4 within the bearing 6. A gear 8 is provided on the outer surface of one end of each roller 4 close to the bearing 6, and a set of gears 8 are meshed with each other. At the same time, the tooth blocks of the gears 8 are of a planar structure. Therefore, the meshing degree between a set of gears 8 can remain relatively stable when the roller 4 moves and will not be affected by the change in the position of the roller 4. This allows the screening machine to have a high degree of flexibility and adjustability. A set of grooves 9 are provided at one end of the housing 1 away from the gears 8. A convex block 10 that fits the groove 9 is slidably connected to each groove 9. One side of each convex block 10 is slidably connected to a connecting member 11, and the other side of the connecting member 11 is hinged to one end of the corresponding roller 4, enabling the convex block 10 to drive one end of the roller 4 to move. A fixing block 12 is fixedly connected to one side of the housing 1 close to the convex block 10. A clamping block 14 is slidably connected within the fixing block 12, and connecting rods 16 are respectively hinged between the two ends of the clamping block 14 and the corresponding convex block 10, causing the clamping block 14 to slide within the fixing block 12 and then driving the convex block 10 to move within the groove 9 through the transmission of the connecting rod 16. Since the roller 4 and the bearing 6 rotate with the housing 1 through the rotating shaft 7, the other ends of this set of rollers 4 will be driven to move synchronously, thereby changing the relative distance between the rollers 4, making the distance between the rollers 4 from the end close to the gears 8 to the end close to the convex block 10 gradually increase or decrease. Thus, the distance between the rollers 4 can be adjusted according to the screening size requirements of different ball beads without replacing the entire device, facilitating the improvement of work efficiency and the reduction of screening costs.

[0033] Further, the output end of a motor 17 is connected to one end of one of the rollers 4 close to the gears 8. The motor 17 drives one of the rollers 4 to rotate, and then drives the other roller 4 to rotate through a set of rollers 4. The motor 17 is installed within a soundproof box 18, which can fix the motor 17. At the same time, a support block is fixedly connected to one side of the housing 1. An arc-shaped slider 20 is fixedly connected to the bottom of the soundproof box 18, and an arc-shaped chute 19 that fits the arc-shaped slider 20 is provided at the top of the support block, enabling the soundproof box 18 to slide on the top of the support plate through the arc-shaped chute 19 and the arc-shaped slider 20. Since the arc-shaped slider 20 rotates concentrically with the rotating shaft 7, the motor 17 can move synchronously with the roller 4, which can avoid affecting the driving of the roller 4, thus ensuring the stability and continuity of the screening process.

[0034] Meanwhile, a clamping groove 13 is provided inside the fixed block 12. A clamping block 14 that fits with the clamping groove 13 is slidably connected inside the clamping groove 13. A threaded rod 15 that fits with the clamping block 14 is rotatably connected inside the clamping groove 13, and the clamping block 14 moves on the outer surface of the threaded rod 15. The top of the threaded rod 15 movably penetrates through the top of the fixed block 12 and extends to the outside. Then, by rotating the threaded rod 15, the clamping block 14 can be driven to move inside the clamping groove 13, thereby realizing the adjustment of the position of the clamping block 14, and thus realizing the adjustment of the position of the bump 10.

[0035] In this embodiment, a conveying device 21 is installed at one end of the housing 1 close to the second support rod 3. A funnel 22 is provided at one end of a set of roller shafts 4 close to the conveying device 21, and the outlet of the conveying device 21 coincides with the top opening of the funnel 22, so that the conveying device 21 can continuously convey the to-be-screened beads into the funnel 22. Then, through the funnel 22, it is ensured that the beads are smoothly transferred from the conveying device 21 to the area of the roller shafts 4 for screening. The funnel 22 is connected to the housing 1 through a bracket 23, then the position of the funnel 22 can be fixed. And a plurality of limiting grooves 25 are provided at the inner bottom of the housing 1. A limiting block 26 that fits with the limiting groove 25 is slidably connected inside each limiting groove 25. The top of each limiting block 26 is fixedly connected with a collection frame 24. By means of the connection between the collection frame 24 and the limiting groove 25 through the limiting block 26, the disassembly and assembly become simple and fast. Also, the position of the collection frame 24 can be limited by the limiting block 26 to prevent it from displacing inside the housing 1 and affecting the collection of the screened beads. And the collection frame 24 is located below a set of roller shafts 4, so that the screened beads can directly fall into the collection frame 24, which is convenient for improving work efficiency.

[0036] Although the embodiments of the present invention have been shown and described, this specific embodiment is only an explanation of the present invention, and it is not a limitation of the invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations without creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
