Description

Technical Field

[0001] This utility model relates to the field of sintering machine technology, and in particular to a dry sintering machine. Background Technology

[0002] Dry polishing machines are surface treatment equipment without liquid media. Their core function is to deburr, round corners, polish surfaces, and remove oxide scale from workpieces made of metal, plastic, and other materials through physical grinding. They are widely used in automotive parts, electronic components, precision hardware, and other fields. Compared with traditional wet polishing machines, they do not require subsequent drying or wastewater treatment, and have significant advantages such as environmental protection, energy saving, and no risk of workpiece corrosion. Their main structure includes a drive system, grinding media, dust removal system, frame, and protective system.

[0003] In current mainstream dry calender designs, a direct motor-driven spindle transmission mode is commonly used. The spindle, as the core power transmission component, drives the large drum within the equipment to complete the surface treatment process of the material. This transmission structure places extremely stringent requirements on the geometric precision of the spindle during operation. Since the spindle must simultaneously bear the dual functions of power output and drum support, its straightness directly determines the stability of the drum's rotation trajectory. Deviations in straightness can easily lead to eccentric rotation of the drum, affecting the uniformity of material processing. Concentricity, on the other hand, is directly related to the coaxiality of power transmission. If concentricity is not met, it will... Additional radial force is generated during transmission, which disrupts the stability of equipment operation. When the equipment is running at high speed, the spindle is constantly subjected to the combined stress of the roller's own weight, material load, and the transmission process. Under such conditions for a long time, the friction between the spindle and mating parts such as bearings will be significantly enhanced. This will not only accelerate the wear on the spindle surface, but may also cause an abnormal increase in the mating clearance. This cumulative wear will not only further reduce the spindle's accuracy retention, leading to a gradual decline in the equipment's machining accuracy, but will also increase the equipment's failure rate and prolong downtime for maintenance, which will have an adverse impact on overall production efficiency and operating cost control.

[0017] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a dry sizing machine, including a frame 1, with a rotating mechanism 2 installed on both the left and right sides of the frame 1. The rotating mechanism 2 drives the equipment to rotate. An adjustment mechanism 3 is provided on the right side of the frame 1. The adjustment mechanism 3 adjusts the position of the guide wheel. The rotating mechanism 2 includes a central shaft 201, which is rotatably connected to the top of the frame 1. A drive turntable 203 is rotatably connected to the left end of the central shaft 201. Rotating components 202 are installed on the left side and bottom of the drive turntable 203. A driven turntable 204 is rotatably connected to the right end of the central shaft 201. Auxiliary components 205 are installed on the bottom and right side of the driven turntable 204. Multiple connecting rods 206 are equidistantly arranged around the outer perimeter of the central shaft 201. The rotating assembly 202 includes a main motor 2021, which is mounted on the bottom left side of the frame 1. The main motor 2021 is model Y132M-4. It generates a rotating magnetic field by passing three-phase alternating current through the stator winding, causing the rotor to rotate following the magnetic field under the action of the magnetic field force. The output end of the main motor 2021 is fixedly connected to the drive wheel 2022. The outer wall of the drive wheel 2022 is driven by a belt 2023. The top inner wall of the belt 2023 is driven by the left side of the outer wall of the drive turntable 203. The auxiliary component 205 includes an auxiliary motor 2051, which is installed on the bottom right side of the frame 1. The auxiliary motor 2051 is model Y132M-4. It generates a rotating magnetic field by passing three-phase AC power through the stator winding, so that the rotor is rotated following the magnetic field under the action of the magnetic field force. The output end of the auxiliary motor 2051 is fixedly connected to a sprocket 2052. A chain 2053 is meshed with the outer wall of the sprocket 2052. A sprocket 2054 is meshed with the top inner side of the chain 2053. The sprocket 2054 is fixedly connected to the right side of the middle part of the driven turntable 204. The top and bottom walls of the right side of the middle part of the driven turntable 204 are provided with grooves 5. Motor brackets 6 are fixedly connected to the bottom left and right sides of the frame 1, and the top walls of the motor brackets 6 are fixedly connected to the bottom walls of the main motor 2021 and the auxiliary motor 2051. Specifically, the central shaft 201 horizontally spans the middle frame of the machine frame 1, and its two ends are fixed to the two side columns of the machine frame 1 by bearing seats. The central shaft 201 passes through the central through holes of the drive turntable 203 and the driven turntable 204 in sequence, which serves to install and fix the two turntables so that they can rotate freely around the central shaft 201. The main motor 2021 is fixed to the bottom platform of the machine frame 1 by bolts. The output shaft of the main motor 2021 engages with the central hole of the drive wheel 2022, driving the drive wheel 2022 to rotate. The drive wheel 2022 transmits power to the wheel groove on the edge of the drive turntable 203 through the belt 2023 sleeved in its wheel groove. The drive turntable 203... Link 206 is rigidly connected to driven turntable 204. When drive turntable 203 rotates under power, driven turntable 204 starts to rotate synchronously with drive turntable 203 at the same speed under the synchronous drive of the three link 206. Auxiliary motor 2051 is mounted on a bracket on the side of frame 1 near driven turntable 204. The output shaft of auxiliary motor 2051 is fixedly connected to sprocket 1 2052, which drives sprocket 1 2052 to rotate. The power is transmitted to sprocket 2054 through chain 2053 wrapped in the tooth grooves of sprocket 1 2052 and sprocket 2 2054, which drives drive turntable 203 and driven turntable 204 to rotate together to ensure smooth rotation.

[0018] Reference Figure 2 and Figure 5 The adjusting mechanism 3 includes a mounting ring 301, which is fixedly connected to the outer wall of the driven turntable 204. Rotating handles 302 are rotatably connected to the middle of the front and rear sides of the mounting ring 301. Screw assemblies 303 are installed on the inner sides of the two rotating handles 302. The screw assembly 303 includes an adjusting screw 3031, which is fixedly connected to the end of the mounting ring 301. A screw nut 3032 is threadedly connected to the outer wall of the adjusting screw 3031. A wheel axle 3033 is fixedly connected to the right side of the middle part of the screw nut 3032. Both lead screw nuts 3032 have multiple sliding tenons 4 fixedly connected at equal intervals on their outer walls. Specifically, when the position of the guide wheel needs to be adjusted, the operator holds the end of the rotating handle 302 and rotates it clockwise or counterclockwise. One end of the rotating handle 302 is fixedly connected to one end of the adjusting screw 3031 via a coupling, causing the adjusting screw 3031 to rotate synchronously around its own axis. Both ends of the adjusting screw 3031 are fixed in the preset mounting holes inside the driven turntable 204, and its axial and radial positions are fixed and cannot move. As the adjusting screw 3031 rotates, the guide wheel... The screw nut 3032, whose outer and inner threads engage with the outer thread of the adjusting screw 3031, will move back and forth along the axis of the adjusting screw 3031. The outer side of the screw nut 3032 is fixedly connected to one end of the wheel axle 3033. The threads of the adjusting screw 3031 and the screw nut 3032 have a self-locking function, that is, after the adjusting screw 3031 is stopped from rotating, the screw nut 3032 can remain in the current position, preventing the wheel axle 3033 from being abnormally displaced due to external force after adjustment.

[0019] Reference Figure 1 and Figure 3 The inner and outer walls of the driving turntable 203 and the driven turntable 204 are equidistantly connected to the connecting shafts 8, and the ends of the multiple connecting shafts 8 are fixedly connected to the grinding grooves 7. Specifically, the grinding groove 7 revolves around the central axis 201 along with the rotation of the driven turntable 204 and the driving turntable 203 via the connecting shaft 8, thereby achieving the purpose of grinding.

[0020] Working principle: The central shaft 201 spans the middle of the frame 1, passing through the drive turntable 203 and the driven turntable 204, serving as a mounting and fixing mechanism. The main motor 2021 drives the drive wheel 2022 to rotate, which transmits power to the drive turntable 203 via the belt 2023. The drive turntable 203 is rigidly connected to the driven turntable 204 via the connecting rod 206. When the drive turntable 203 rotates, the driven turntable 204 begins to rotate synchronously with the drive turntable 203 under the drive of the connecting rod 206, assisting in rotation. Motor 2051 drives sprocket 2052 to rotate, and transmits power to sprocket 2054 through chain 2053. Sprocket 2054 is directly connected to driven turntable 204. Auxiliary main motor 2021 drives drive turntable 203 and driven turntable 204 to rotate together. This set of equipment transmits power to drive turntable 203 and driven turntable 204 themselves, instead of transmitting power through central shaft 201, which solves the problem in the prior art that the main shaft will wear out more and more with the use of the equipment. When the position of the guide wheel needs to be adjusted, rotate the rotating handle 302 to drive the adjusting screw 3031 to rotate synchronously. The adjusting screw 3031 is fixed inside the driven turntable 204 by bearings, and its position is fixed. As the adjusting screw 3031 rotates, the screw nut 3032 will move back and forth, and the threads of both have a self-locking function to prevent abnormal displacement of the wheel axle 3033 after adjustment. This mechanism can adjust the position of the guide wheel in real time as needed, increasing the stability of the equipment operation.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
