[0002] In the field of industrial product surface treatment, texture polishing is a key process to improve the appearance and performance of products.

[0003] Currently available texture polishing equipment generally suffers from insufficient automation. Most machines can only perform polishing in a single direction and cannot flexibly adjust to the texture requirements of different workpiece surfaces, resulting in poor polishing effects and failing to meet diverse processing needs. Furthermore, the texture polishing mechanisms of existing equipment often employ a fixed structure design, preventing the polishing belt from vibrating within a small range according to polishing requirements, leading to suboptimal polishing quality and difficulty in achieving ideal results. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a fully automatic texture polishing machine, which aims to solve the problem that existing texture polishing machines are unable to achieve the ideal polishing effect.

[0005] The present invention adopts the following technical solution:

[0006] The fully automatic texture polishing machine includes a cabinet containing a conveyor table. The upper part of the cabinet has doors on both the left and right sides facing the conveyor table. Multiple texture polishing mechanisms are housed within the cabinet. Each texture polishing mechanism includes a fixed frame mounted on the cabinet. A lifting frame slides within the fixed frame. A lifting drive assembly is mounted on the fixed frame, driving the lifting frame to move up and down. A sliding carriage that can move left and right is located within the lifting frame. A left-right drive assembly is also mounted on the lifting frame to drive the sliding carriage's left and right movement. A swing frame is located below the sliding carriage. A pair of connecting shafts rotate vertically on the sliding carriage. The tops of the connecting shafts are connected by a belt, and the bottoms of the connecting shafts have an eccentric shaft. The swing frame is mounted to the end of the eccentric shaft and has a rotatable polishing belt. A counterweight seat is mounted on the eccentric shaft, and a counterweight plate is mounted on the counterweight seat. The lifting frame has a swing drive assembly to drive the connecting shafts to rotate.

[0007] Furthermore, each of the connecting shafts is provided with a pulley at its top, and a matching belt is fitted between the pulleys. The swing drive assembly includes a fixed seat mounted on the lifting frame, and a swing motor is provided on the fixed seat. The drive shaft of the swing motor is provided with a first universal joint, and the other end of the first universal joint is rotatably connected to the connecting shaft at the same position.

[0008] Furthermore, the left and right drive assembly includes a movable motor mounted on the lifting frame, the drive shaft of the movable motor is provided with an eccentric wheel, and a pull rod is rotatably provided at the eccentric position of the eccentric wheel, the end of the pull rod being rotatably connected to the corresponding position of the slide.

[0009] Furthermore, the lifting drive assembly includes a pair of left and right top seats mounted on the top of the fixed frame. A set of worm gear lifts is vertically mounted on the top seats, and a coupling is rotatably connected between the two top seats. Both ends of the coupling are equipped with linkage sprockets. One end of the input shaft of the worm gear lift is equipped with a driven sprocket. Matching linkage chains are provided between the linkage sprockets and driven sprockets on the same side. The other end of the input shaft of one worm gear lift is equipped with a driving sprocket. A lifting motor is mounted on the top seat on the same side as the driving sprocket. The lifting motor drives the driving sprocket to rotate through the chain.

[0010] Furthermore, a pair of grinding rollers are rotatably mounted on the swing frame, with a matching polishing belt fitted between the grinding rollers. A grinding motor is mounted on the lifting frame, and a second universal joint is rotatably mounted on the drive shaft of the grinding motor.

[0024] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0025] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0026] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0027] Combination Figure 1-6 As shown, the fully automatic texture polishing machine includes a cabinet 1, a conveyor table 2 inside the cabinet 1, and doors 3 on both the left and right sides of the upper part of the cabinet 1 facing the conveyor table 2. Multiple texture polishing mechanisms are installed inside the cabinet 1. Each texture polishing mechanism includes a fixed frame 4 mounted on the cabinet 1, a lifting frame 5 slidably mounted inside the fixed frame 4, and a lifting drive assembly on the fixed frame 4. The lifting drive assembly drives the lifting frame 5 to move up and down. A sliding carriage 6 that can move left and right is installed inside the lifting frame 5, and a left and right drive assembly is also provided on the lifting frame 5 to drive the sliding carriage 6 to move left and right. Figure 4As shown, a swing frame 9 is located below the slide 6, combined with... Figure 5-7 As shown, the slide 6 has a pair of vertically rotatable connecting shafts 7. The top of the connecting shafts 7 is connected by a belt 14, and the bottom of the connecting shafts 7 has an eccentric shaft 8. The swing frame 9 is installed at the end of the eccentric shaft 8. The swing frame 9 is provided with a rotatable polishing belt 10. The eccentric shaft 8 is provided with a counterweight seat 11, and the counterweight seat 11 is provided with a counterweight plate 12. The lifting frame 5 is provided with a swing drive assembly for driving the connecting shafts 7 to rotate.

[0028] In this device, the cabinet serves as the main frame of the entire equipment, providing installation space and protection for the internal components. The cabinet contains a conveyor platform that carries the workpieces to be polished and transports them to the working area of ​​the texture polishing machine. The diagram shows three spaced-apart texture polishing mechanisms, allowing for simultaneous multi-station polishing of workpieces and improving polishing efficiency. The upper part of the cabinet has doors on both sides facing the conveyor platform, facilitating equipment maintenance and repair, as well as workpiece loading and unloading operations.

[0029] When using this device to texture a workpiece, firstly, based on the thickness of the workpiece, the lifting drive assembly moves the lifting frame up and down to adjust the distance between the polishing belt and the conveyor table, ensuring that the polishing belt makes full contact with the workpiece surface. Then, the workpiece is placed at the input end of the conveyor table, which moves the workpiece into the cabinet.

[0030] When the workpiece moves to the bottom of the texture polishing mechanism, the polishing belt rotates to polish the workpiece surface. During the polishing process, the left and right drive components drive the carriage to move left and right, expanding the polishing range of the polishing belt. The swing drive components drive the swing frame and the polishing belt to vibrate in a small range in the horizontal plane, so that the polishing belt polishes the texture of the workpiece surface in a specific motion trajectory in the horizontal plane.

[0031] In this structure, the connecting shaft 7 rotates, while the eccentric shaft 8 is eccentrically positioned to the connecting shaft 7. Therefore, during the rotation of the connecting shaft 7, it can drive the eccentric shaft 8 to rotate around the connecting shaft 7 as its axis. The swing frame is installed at the bottom of the eccentric shaft 8, thus allowing the swing frame to vibrate within a small range. This is a specific structural feature. Figure 4-5 In the process, each of the connecting shafts 7 is provided with a pulley 13 at its top, and a matching belt 14 is fitted between the pulleys 13. The swing drive assembly includes a fixed seat 15 mounted on the lifting frame 5. The fixed seat 15 is provided with a swing motor 16. The drive shaft of the swing motor 16 is provided with a first universal joint 17 (both ends of the universal joint are universal joints). The other end of the first universal joint 17 is connected to the connecting shaft 7 at the same position.

[0032] When the workpiece is textured and polished, the swing drive assembly drives the swing frame to swing. Specifically, the swing motor starts to work and drives the corresponding connecting shaft to rotate through the first universal joint. Under the transmission action of the belt and pulley, the two connecting shafts rotate synchronously, driving the eccentric shaft and the swing frame to swing, so that the polishing belt swings and polishes the workpiece surface to adapt to the polishing requirements of different textures on the workpiece surface.

[0033] The eccentric shaft is equipped with a counterweight seat, which has multiple counterweight plates. In practice, the counterweight plates can be added or removed according to actual polishing needs to adapt to different polishing requirements.

[0034] In this device, combined Figure 3-4 The left and right drive assembly includes a moving motor 18 mounted on the lifting frame 5. The drive shaft of the moving motor 18 is equipped with an eccentric wheel 19. A pull rod 20 is rotatably mounted at the eccentric position of the eccentric wheel 19. The end of the pull rod 20 is rotatably connected to a corresponding position on the slide 6. When the moving motor starts, it drives the eccentric wheel to rotate, which in turn pulls the slide to move left and right within the lifting frame via the pull rod. This, in turn, moves the polishing belt left and right, achieving comprehensive polishing of the workpiece surface and avoiding polishing dead angles.

[0035] As a preferred structure, the lifting drive assembly includes a pair of left and right top seats 21 mounted on the top of the fixed frame 4. A set of worm gear lifters 22 is vertically mounted on the top seats 21, and a coupling rod 23 is rotatably connected between the two top seats 21. Both ends of the coupling rod 23 are provided with linkage sprockets 24. One end of the input shaft of the worm gear lifter 22 is provided with a driven sprocket 25. A matching linkage chain (not shown in the figure) is provided between the linkage sprockets 24 and the driven sprockets 25 on the same side. The other end of the input shaft of one of the worm gear lifters 22 is provided with a driving sprocket 27. A lifting motor 28 is provided on the top seat 21 on the same side as the driving sprocket 27. The lifting motor 28 drives the driving sprocket 27 to rotate through the lifting chain.

[0036] During the texture polishing process of the workpiece, when the polishing belt needs to move up and down, the lifting motor starts working. This drives the drive sprocket to rotate via the lifting chain, which in turn drives the corresponding worm gear lift. Under the transmission action of the coupling, drive sprocket, driven sprocket, and drive chain, the two sets of worm gear lifts work synchronously, causing the lifting frame to move up and down, thus adjusting the height of the polishing belt.

[0037] A pair of grinding rollers 26 are rotatably mounted on the swing frame 9, with a matching polishing belt 10 fitted between them. The polishing belt can move with the rotation of the grinding rollers to polish the surface of the workpiece. A grinding motor 30 is mounted on the lifting frame 5, and the drive shaft of the grinding motor 30 is equipped with a second universal joint 31, which is connected to one end of the corresponding grinding roller.

[0038] When the grinding motor starts, it drives the grinding roller to rotate via the second universal joint, which in turn drives the polishing belt to move, thus achieving texture polishing of the workpiece surface. During texture polishing, the second universal joint accommodates small-distance movements of the swing frame.

[0039] like Figure 3 The carriage 6 has dust collection covers 32 facing downwards on both the front and rear sides. The bottom of the dust collection cover is set towards the polishing belt. The dust collection cover 32 has an inner cavity and an air intake 33 is opened on the top of the dust collection cover. The inner side of the dust collection cover 32 has dust collection holes (which are covered in the figure).

[0040] The carriage has dust hoods facing downwards on both the front and rear sides, with the bottom of the dust hoods facing the polishing belt. The dust hoods have an inner cavity, and the top of the dust hoods has an air intake. The inner sides of the dust hoods also have suction holes. During the polishing process, the dust hoods draw the generated dust into the inner cavity through the suction holes and then discharge it through the air intake.

[0041] Combination Figure 1 , Figure 3 The top surface of the cabinet 1 is provided with a dust collection seat 34. The dust collection seat 34 has a confluence chamber. The front of the dust collection seat 34 has several round openings 35, and the back has a connection port 36. The round openings 35 are connected to flexible hoses. The flexible hoses pass into the cabinet and are connected to the corresponding air intake 33. A dust collection device 37 is provided in the cabinet 1 below the conveyor table. The dust collection device is connected to the connection port through a dust collection pipe.

[0042] The vacuum cleaner generates negative pressure, which draws dust from the vacuum hood into the vacuum cleaner through the hose, vacuum seat, and vacuum pipe for collection and processing. This effectively reduces dust in the work environment, protecting the health of operators and ensuring the normal operation of the equipment.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
