Description

Technical Field

[0001] This utility model relates to the field of automotive gasket polishing technology, specifically to a planetary centrifugal polishing machine for processing automotive gaskets. Background Technology

[0002] Planetary centrifugal polishing machines for processing automotive gaskets work by simultaneously rotating and revolving a drum containing the gasket, polishing stones, polishing aids, and water. Centrifugal force generates strong and uniform friction between the gasket and the polishing media. This efficiently removes burrs, scale, oil, and other impurities from the surface of the automotive gasket, improving its surface finish while maintaining its original dimensions and shape.

[0003] In the existing technology, when processing automotive gaskets using a planetary centrifugal polishing machine, the traditional manual feeding method involves placing the gaskets into the drum and directly dumping them in batches. This causes the gaskets to tend to accumulate in one place within the drum, resulting in some gaskets being completely enveloped by the polishing medium and unable to fully contact the grinding medium. This leads to localized over-polishing and localized unpolished areas, resulting in poor polishing uniformity. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a planetary centrifugal polishing machine for processing automotive gaskets, which solves the technical problems of direct batch dumping, gasket accumulation, and poor polishing uniformity in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a planetary centrifugal polishing machine for processing automotive gaskets, comprising: The polishing machine body has a controller on its front surface, a door groove at the top of the polishing machine body, a door assembly inside the door groove, a roller inside the polishing machine body, and a feeding mechanism at the top of the roller. The feeding mechanism includes a connecting box, a baffle plate, and a distributing component. The connecting box is fixedly installed on the top wall of the drum, the baffle plate is located inside the connecting box, and the distributing component is located on one side of the baffle plate. The distributing component is used to disperse and feed automotive gaskets into the drum.

[0006] For example, at least one embodiment of this utility model provides a planetary centrifugal polishing machine for processing automotive gaskets. The top of the connecting box is provided with a square groove, and an inlet is fixedly installed at the upper end of the square groove. A sealing cover is provided at the top of the inlet. Two inclined flow plates are provided, and the two inclined flow plates are symmetrically arranged below the inlet. The ends of the two inclined flow plates that are close to each other are fixedly connected.

[0007] For example, at least one embodiment of this utility model provides a planetary centrifugal polishing machine for processing automotive gaskets, wherein baffles are fixedly installed at the front and rear ends of the two inclined flow plates, and the top of the baffle near the feed inlet is fixedly connected to the top wall inside the connecting box.

[0008] For example, at least one embodiment of this utility model provides a planetary centrifugal polishing machine for processing automotive gaskets. The material distribution assembly is provided in two sets, and the two sets of material distribution assemblies are symmetrically arranged at the ends of two inclined plates away from each other. The material distribution assembly includes a material distribution barrel. The top and bottom ends of the material distribution barrel are respectively fixedly installed on the top and bottom walls inside the connecting box. A slot is opened on the side of the material distribution barrel near the inclined plate, and one end of the inclined plate is inserted into the material distribution barrel through the slot.

[0009] For example, at least one embodiment of this utility model provides a planetary centrifugal polishing machine for processing automotive gaskets. The dispensing hopper is equipped with a motor. One end of the motor is fixedly installed on the top wall inside the dispensing hopper. The output end of the motor is fixedly installed with a rotating shaft. The bottom end of the rotating shaft is rotatably installed on the bottom wall inside the dispensing hopper. The outer surface of the lower end of the rotating shaft is provided with a bearing. The inner ring surface of the bearing is fixedly connected to the outer surface of the rotating shaft. The outer ring surface of the bearing is provided with a push plate.

[0010] For example, at least one embodiment of this utility model provides a planetary centrifugal polishing machine for processing automotive gaskets. The pusher plate is provided with four push plates, and the four push plates are fixedly installed at equal distances on the outer ring surface of the bearing at their closest ends. Triangular blocks are fixedly installed on the top wall of the push plate. The bottom wall of the material distribution barrel is provided with four feeding grooves at equal distances. The top wall of the roller is provided with a through groove corresponding to the feeding groove position.

[0011] For example, at least one embodiment of this utility model provides a planetary centrifugal polishing machine for processing automotive gaskets. The machine door assembly includes two symmetrically arranged arc-shaped doors. Slide tracks are provided on both sides of the door groove. Both ends of the two arc-shaped doors are slidably installed in the slide tracks. Receiving grooves are provided at the upper and lower ends of the door groove.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-4 As shown, it illustrates a planetary centrifugal polishing machine for processing automotive gaskets according to one embodiment of the present invention, comprising: The polishing machine body 1 has a controller 2 on its front surface, a door groove 7 at the top of the polishing machine body 1, an organic door assembly 3 inside the door groove 7, a roller 4 inside the polishing machine body 1, and a feeding mechanism 5 at the top of the roller 4. The feeding mechanism 5 includes a connecting box 51, a baffle plate 53, and a distributing component 55. The connecting box 51 is fixedly installed on the top wall of the roller 4. The baffle plate 53 is located inside the connecting box 51. The distributing component 55 is located on one side of the baffle plate 53. The distributing component 55 is used to disperse the automotive gaskets into the roller 4. The baffle plate 53 can guide the feeding direction and buffer the impact, allowing the automotive gaskets to slide slowly into the roller 4 along the inclined surface, instead of falling directly vertically. The distributing component 55 can prevent the automotive gaskets from accumulating. When a batch of automotive gaskets are fed in, the distributing component 55 will evenly distribute the automotive gaskets into the roller 4.

[0024] In some examples, such as Figure 2 As shown, the door assembly 3 includes two symmetrically arranged arc-shaped doors 31. Slide tracks 6 are provided on both sides of the door groove 7. Both ends of the two arc-shaped doors 31 are slidably installed in the slide tracks 6. Receiving grooves are provided at the upper and lower ends of the door groove 7. The ends of the two arc-shaped doors 31 that are far apart are located in the receiving grooves. A rubber layer 32 is fixedly installed on the side wall of the two arc-shaped doors 31 that are close to each other.

[0025] Two curved doors 31 are symmetrically arranged, with both ends embedded in the slide rails 6 on both sides of the door groove 7. They can slide in both directions along the slide rails 6, opening to the sides or closing to the middle. The receiving grooves at the upper and lower ends of the door groove 7 provide sliding space for the curved doors 31. When closed, the ends of the curved doors 31 that are close together are joined together. When opened, they are stored in the receiving grooves without occupying external space. The rubber layers 32 on the side of the two curved doors 31 fit tightly together when closed to form a sealing surface.

[0026] Handles 33 are fixedly installed on the top wall of the two curved doors 31 near each other. A connecting block 34 is fixedly installed on the top of one of the handles 33. A threaded hole is opened on the other end of the connecting block 34, and a bolt 35 is threadedly connected in the threaded hole. A threaded hole is opened on the top of the other handle 33. After the curved door 31 is closed, the bolt 35 on the connecting block 34 is rotated to make it threadedly connected to the threaded hole at the top of the other handle 33.

[0027] The two curved doors 31 are firmly locked. When the polishing machine is working, the high-speed revolution and rotation of the roller 4 generate strong vibrations. The bolts 35 are tightened to ensure that the curved doors 31 will not loosen due to vibration, thus avoiding safety hazards. At the same time, the sealing effect of the rubber layer 32 is maintained to ensure the stability of the polishing process.

[0028] During feeding, turn bolt 35 to unlock, grasp handle 33 to push the two arc-shaped doors 31 to the sides and store them into the receiving slot, exposing the feeding mechanism 5 at the top of the roller 4. The automotive gaskets are then fed through the inlet 52. After feeding, push handle 33 to close the two arc-shaped doors 31 in the middle, and the rubber layer 32 fits tightly. Turn bolt 35 to screw it into the threaded hole on the other side to lock the door, ensuring sealing and fixation. Set the parameters through controller 2 to start the equipment. When the roller 4 rotates at high speed, the arc-shaped doors 31 remain stable under the locking of bolt 35 and the limiting action of slide 6. The rubber layer 32 effectively seals, preventing polishing liquid from splashing and noise from leaking out.

[0029] In some examples, such as Figure 4 As shown, a square groove 11 is provided at the top of the connecting box 51. An inlet 52 is fixedly installed at the upper end of the square groove 11. A sealing cover 56 is provided at the top of the inlet 52. Two inclined flow plates 53 are provided. The two inclined flow plates 53 are symmetrically arranged below the inlet 52. The two inclined flow plates 53 are fixedly connected at their closest ends. The car gasket is slowly slid in along the inclined surface, instead of falling directly vertically, avoiding the corners from being bumped and the surface from being scratched.

[0030] Both inclined plates 53 are fixedly installed with baffles 54 at their front and rear ends. The top of the baffle 54 near the feed inlet 52 is fixedly connected to the top wall inside the connecting box 51.

[0031] Open the sealing cover 56 and feed the automotive gasket through the inlet 52. After falling from the inlet 52, the gasket slides down the inclined surfaces of the two side baffles 53, reducing the falling speed and avoiding edge and corner damage caused by vertical fall. The baffle 54 can prevent the gasket from falling from the front and rear sides of the baffle 53 into the gap inside the connecting box 51 when it slides down, ensuring that the gasket can enter the roller 4 along the baffle 53. The baffle 54 restricts the sliding trajectory of the gasket and prevents the thin gasket from shifting due to inertia.

[0032] In some examples, such as Figure 4 , Figure 5 and Figure 6 As shown, there are two sets of material distribution components 55, which are symmetrically arranged at the ends of the two inclined plates 53 away from each other. Each material distribution component 55 includes a material distribution barrel 551. The top and bottom ends of the material distribution barrel 551 are fixedly installed on the top and bottom walls of the connecting box 51, respectively. A slot 10 is provided on the side of the material distribution barrel 551 near the inclined plate 53. One end of the inclined plate 53 is inserted into the material distribution barrel 551 through the slot 10. The material distribution barrel 551 is fixed to the top and bottom walls of the connecting box 51. The connection between the inclined plate 53 and the material distribution barrel 551 is formed by the insertion of one end of the inclined plate 53 into the material distribution barrel 551, which can prevent the gasket from getting stuck or leaking at the connection between the inclined plate 53 and the material distribution barrel 551, and ensure that all gaskets can enter the material distribution barrel 551.

[0033] A motor 552 is installed inside the dispensing hopper 551. One end of the motor 552 is fixedly installed on the top wall inside the dispensing hopper 551. A rotating shaft 553 is fixedly installed at the output end of the motor 552. The bottom end of the rotating shaft 553 is rotatably installed on the bottom wall inside the dispensing hopper 551. A bearing 554 is provided on the outer surface of the lower end of the rotating shaft 553. The inner ring surface of the bearing 554 is fixedly connected to the outer surface of the rotating shaft 553. A push plate 555 is provided on the outer ring surface of the bearing 554. The motor 552 is fixed to the top of the dispensing hopper 551 and drives the bearing 554 and the push plate 555 to rotate through the rotating shaft 553. The bearing 554 ensures the stability of the rotating shaft 553 during rotation and reduces shaking.

[0034] Four push plates 555 are provided. The four push plates 555 are fixedly installed at equal distances on the outer ring surface of the bearing 554 at one end closest to each other. Triangular blocks 556 are fixedly installed on the top wall of the push plate 555. Four feeding grooves 9 are opened at equal distances on the bottom wall of the material distribution barrel 551. A through groove 8 is opened on the top wall of the roller 4 corresponding to the feeding groove 9. Triangular blocks 556 prevent multiple gaskets from accumulating on the surface of the push plate 555.

[0035] The motor 552 of the material distribution assembly 55 is started. The motor 552 drives the rotating shaft 553 to rotate. The rotating shaft 553 drives the four push plates 555 to rotate through the bearing 554. The pads slide from the inclined plate 53 into the material distribution barrel 551. The four equidistant push plates 555 continue to rotate, pushing the pads evenly along the bottom wall of the material distribution barrel 551 to avoid local accumulation of the pads in the barrel. The four discharge grooves 9 on the bottom wall of the material distribution barrel 551 are connected to the through grooves 8 on the top wall of the roller 4. The pads pushed by the push plates 555 fall into different areas of the roller 4 through the four discharge grooves 9, achieving uniform feeding. After feeding is completed, the sealing cover 56 and the machine door assembly 3 are closed. The polishing parameters are set through the controller 2, and the polishing machine is started.

[0036] Working principle: When the equipment is in standby mode, the arc-shaped door 31 is locked and closed. When feeding materials, the operator needs to turn the bolt 35 on the connecting block 34 at the top of one of the handles 33 to disengage it from the threaded hole of the other handle 33 and release the mechanical lock. Then, holding the handle 33, the operator pushes the two arc-shaped doors 31 to both sides along the slide rails 6 on both sides of the door groove 7. The end of the arc-shaped door 31 that is furthest away gradually slides into the receiving groove at the top and bottom of the door groove 7. After it is fully opened, the feeding mechanism 5 at the top of the roller 4 is exposed. The sealing cover 56 at the top of the feed port 52 is opened. The sealing cover 56 can keep the inside of the connecting box 51 clean when not feeding materials. A batch of automotive gaskets is poured into the feed port 52 at once. The gaskets fall into the V-shaped double inclined plate 53 below through the feed port 52 and slowly slide down the smooth inclined plate surface. Pushing the handle 33 closes the two arc-shaped doors 31 in the middle, and the rubber layer 32 fits tightly. Turn the bolt 35 to screw it into the thread on the other side. The hole is tightened to maintain the sealing effect of the rubber layer 32. The motor 552 of the dispensing assembly 55 is started. The motor 552 drives the rotating shaft 553 to rotate. The rotating shaft 553 drives the four push plates 555 to rotate synchronously through the bearing 554. The gasket slides along the inclined plate 53 to the end and enters the dispensing barrel 551 through the slot 10 on the side of the dispensing barrel 551. The gasket slides into the dispensing barrel 551 from the inclined plate 53. The four equally spaced push plates 555 continue to rotate, pushing the gasket evenly along the bottom wall of the dispensing barrel 551. The gasket pushed by the push plates 555 falls into different areas of the roller 4 through the four discharge slots 9, realizing feeding. After feeding is completed, the sealing cover 56 is closed. The polishing parameters speed and time are set by the controller 2. The polishing machine starts. After polishing is completed, the equipment stops automatically. Turn the bolt 35 to unlock the machine door, push open the arc door 31, and take out the polished car gasket from the roller 4.
