Description

Technical Field

[0001] This invention relates to the field of injection molding panel processing technology, and in particular to a polishing machine for injection molding panel processing. Background Technology

[0002] Injection-molded panels are panels made through injection molding. Plastic panels are panels made of plastic materials through injection molding. One step in the processing of injection-molded panels is to polish both sides to improve the quality and gloss of both sides of the panel. When polishing injection-molded panels, soft polishing brushes are generally used. However, a polishing machine for injection-molded panel processing is required for polishing.

[0003] However, traditional polishing machines for injection molded panels still have some problems during use. Traditional polishing machines for injection molded panels generally use a single-sided polishing method, polishing one side first and then the other side. This results in a waste of time and low work efficiency when polishing injection molded panels. Therefore, a polishing machine for injection molded panels is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a polishing machine for injection molded panels, which solves the problem that traditional polishing machines for injection molded panels generally use a single-sided polishing method, where the other side is polished after one side is finished, which is time-consuming.

[0006] The polishing structure includes a storage box mounted on the top of a fixed frame, a first bidirectional screw mounted in the middle of the fixed frame, a first threaded sleeve mounted on the outside of the first bidirectional screw, a connecting rod fixed on the outside of the first threaded sleeve, a mounting box fixed on one side of the connecting rod, a rotating gear mounted on one side of the inside of the mounting box, a rotating shaft mounted inside the rotating gear, a transmission gear set mounted on one side of the rotating gear, and a polishing brush mounted on one end of the transmission gear set.

[0008] Preferably, the drive motor is connected to the water pump via a belt, one end of the water pump is connected to the storage tank, and the other end of the water pump is connected to one end of the annular pipe.

[0009] Preferably, the outer side of the first bidirectional screw is provided with an external thread, the inner side of the first screw sleeve is provided with an internal thread, and the first bidirectional screw and the first screw sleeve form a threaded connection. Two sets of polishing brushes are provided, and the two sets of polishing brushes are symmetrically distributed on one side inside the fixing frame.

[0010] Preferably, the spiral blades are provided in multiple sets, and the multiple sets of spiral blades are distributed in a ring inside the nozzle.

[0011] Preferably, a clamping structure is provided on one side of the mounting bracket. The clamping structure includes a mounting groove inside the mounting bracket, a second bidirectional screw installed inside the mounting groove, a second threaded sleeve installed outside the second bidirectional screw, a fixing plate installed outside the second threaded sleeve, a clamping strip fixed to one end of the fixing plate, a sliding groove inside the clamping strip, a slider installed inside the sliding groove, a connecting block fixed to one side of the slider, springs fixed to both ends of one side of the connecting block, a clamping block fixed to one side of the springs, a mounting base installed on one side of the clamping block, and a cylinder movably installed at the middle position of the mounting base.

[0012] Preferably, a connecting plate is fixed to the bottom end of one side of the fixed plate, a second gear is installed on one side of one end of the connecting plate, a third gear is fixed to the front end of the second gear, a first gear is installed on one side of the second gear, one end of the first gear is connected to one side of one end of the connecting plate, a second rack is fixed to the bottom end of the connecting block, a first rack is installed to the bottom end of the third gear, and the bottom end of the first rack is fixed to the top end of the worktable.

[0013] Preferably, the bottom end of the second rack is provided with a plurality of teeth, which mesh with the first gear.

[0014] Preferably, the clamping strips are provided in two sets, and a panel is provided at the middle position of the two sets of clamping strips. The two sets of clamping strips are symmetrically distributed on both sides of the panel.

[0015] Preferably, a guide rod is provided on one side of the clamping block, and two sets of guide rods are symmetrically distributed on one side of the clamping block.

[0016] The present invention provides a polishing machine for injection molding panel processing, which has the following advantages: by setting a polishing structure, the panel can be polished on both sides at the same time, making the polishing efficiency higher; and by setting a clamping structure, the polishing process is more stable.

[0017] With the polishing structure, the two sets of polishing brushes can polish both sides of the panel at the same time, making the panel polishing more efficient.

[0018] Furthermore, by using the first bidirectional screw and the first screw sleeve together, the spacing between the two sets of polishing brushes can be adjusted, so that the position of the two sets of polishing brushes can be adjusted according to the thickness of the panel, so that it can polish panels of different thicknesses.

[0019] Furthermore, during polishing, the polishing liquid inside the storage tank can be extracted and sprayed by using a water pump and a ring pipe, without the need for additional power. It can also be started or stopped simultaneously with the polishing brush, reducing the waste of polishing liquid.

[0020] Furthermore, the spiral blade configuration can form a spiral channel inside the nozzle to guide the polishing slurry, causing it to expand as it passes through the small hole in the center of the nozzle. This expansion helps to break the polishing slurry into smaller droplets. When the polishing slurry is sprayed out through the nozzle on one side of the small hole, it mixes with air and atomizes, thus spraying the polishing slurry in an atomized manner. This allows the atomized polishing slurry to adhere more evenly to the surface of the panel. Moreover, when the atomized polishing slurry forms a spray, the droplets have lower momentum, which means that when they impact the panel surface, the droplets have less reflectivity and can land more accurately on the processed surface, reducing polishing slurry waste and lowering costs.

[0021] With the clamping structure in place, the panel can be held in place by using two sets of clamping strips during the polishing process, preventing the panel from moving around during polishing.

[0022] Furthermore, as the polishing brush polishes both sides of the panel along a straight line, the first linear motor moves. To make the panel more stable during polishing, the first gear meshes with the first rack, causing the first gear to rotate. This rotation, in turn, meshes with the second gear, driving the third gear to rotate. Since the surface of the third gear meshes with the bottom end of the second rack, it causes the connecting block at the top of the second rack to follow the polishing brush on the panel surface. The connecting block then moves to both sides of the panel, corresponding to the polishing position of the brush, thus clamping the panel and making it more stable during polishing. This completes the clamping process. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-13 The present invention provides a polishing machine for injection molding panel processing, including a worktable 1 and a panel 8. A first linear motor 3 is installed on one side of the top of the worktable 1, and a mounting bracket 2 is installed on the top of the first linear motor 3. A second linear motor 4 is installed on the other side of the top of the worktable 1, and a fixing bracket 5 is installed on the top of the second linear motor 4. A polishing structure 6 is provided on the top of the fixing bracket 5.

[0039] A clamping structure 7 is provided on one side of the mounting bracket 2. The clamping structure 7 includes a mounting groove 7011 opened inside the mounting bracket 2. A second bidirectional screw 7010 is installed inside the mounting groove 7011. A second threaded sleeve 7012 is installed on the outside of the second bidirectional screw 7010. A fixing plate 7013 is installed on the outside of the second threaded sleeve 7012. A clamping strip 704 is fixed to one end of the fixing plate 7013.

[0040] Reference Figures 1-3 and Figures 9-13 As shown: When polishing panel 8, panel 8 is first placed in the middle position of clamping strip 704. During placement, the external power supply starts the second bidirectional screw 7010 to rotate. When the second bidirectional screw 7010 rotates, it works with the second screw sleeve 7012 to drive the two sets of clamping strips 704 to move towards the middle position. As the clamping strips 704 move, the cylinders 7018 on one side of the clamping blocks 702 at both ends of the clamping strips 704 will first contact the two sides of panel 8 to pre-clamp the panel 8. As the clamping strips 704 continue to move, the springs 7014 on one side of the clamping blocks 702 will contract, and then one side of the clamping strips 704 will press against both ends of panel 8 to clamp again, thereby completing the clamping work of panel 8 and preventing panel 8 from moving around during polishing.

[0041] The polishing structure 6 includes a storage box 601 mounted on the top of a mounting frame 5. A first bidirectional screw 608 is mounted in the middle of the interior of the mounting frame 5. A first threaded sleeve 609 is mounted on the outside of the first bidirectional screw 608. A connecting rod 6012 is fixed to the outside of the first threaded sleeve 609. A mounting box 606 is fixed to one side of the connecting rod 6012. A rotating gear 6013 is mounted on one side of the interior of the mounting box 606. A rotating shaft 607 is mounted inside the rotating gear 6013. A transmission gear set 6014 is mounted on one side of the rotating gear 6013. A polishing brush 6010 is mounted at one end of the transmission gear set 6014. A drive motor 603 is mounted on one side of the top of the mounting frame 5. A bevel gear set 604 is mounted on one side of the output end of the drive motor 603. A connecting shaft 605 is mounted at the bottom of one end of the bevel gear set 604. The bottom end of the connecting shaft 605 is connected to the top end of the rotating shaft 607. A water pump 602 is mounted on the side. An annular tube 6015 is mounted on the outer side of a polishing brush 6010 at one end of the mounting box 606. A nozzle 6011 is mounted on one end of the annular tube 6015. A spiral blade 6016 is mounted on one side of the nozzle 6011. A spray hole 6017 is opened on one side of the nozzle 6011. A drive motor 603 is connected to the water pump 602 via a belt. One end of the water pump 602 is connected to a storage tank 601, and the other end of the water pump 602 is connected to the annular tube 6015. One end of the tube 6015 is connected, the outer side of the first bidirectional screw 608 is provided with external thread, the inner side of the first screw sleeve 609 is provided with internal thread, and the first bidirectional screw 608 and the first screw sleeve 609 form a threaded connection. Two sets of polishing brushes 6010 are provided, and the two sets of polishing brushes 6010 are symmetrically distributed on one side inside the fixing frame 5. Multiple sets of spiral blades 6016 are provided, and the multiple sets of spiral blades 6016 are distributed in a ring inside the nozzle 6011.

[0042] Reference Figures 1-8As shown: After panel 8 is clamped, the external power supply starts the first bidirectional screw 608. After starting, the first bidirectional screw 608, in cooperation with the first screw sleeve 609, adjusts the position of the two sets of polishing brushes 6010. When the two sets of polishing brushes 6010 are adjusted to polish both sides of panel 8, they stop moving. During polishing, the drive motor 603 is started. After starting, the drive motor 603 drives the connecting shaft 605 to rotate through the bevel gear set 604. When the connecting shaft 605 rotates, it drives the rotating shaft 607 to rotate. When the rotating shaft 607 rotates, it drives the rotating gear 6013 to rotate. When the rotating gear 6013 rotates, it drives the polishing brushes 6010 to rotate through cooperation with the transmission gear set 6014. Since there are two sets of polishing brushes 6010, both sides of panel 8 can be polished simultaneously, making the polishing efficiency higher. When the drive motor 603 starts, it also drives the belt to rotate the two sets of polishing brushes 6010. The water pump 602 rotates, thereby drawing polishing slurry from the inside of the storage tank 601 and then spraying it out through the nozzle 6011 at the bottom of the annular tube 6015. The connecting pipe between the annular tube 6015 and the water pump 602 is a corrugated pipe, which does not affect the position adjustment of the mounting box 606. When the polishing slurry passes through the inside of the nozzle 6011, the spiral blade 6016 is set to form a spiral channel to guide the polishing slurry, causing it to expand when it passes through the small hole in the middle of the nozzle 6011. This expansion helps to break the polishing slurry into smaller droplets. When the polishing slurry is sprayed out through the nozzle 6017 on one side of the small hole, it mixes with air and atomizes, thus spraying the polishing slurry in an atomized manner. The atomized polishing slurry can adhere more evenly to the surface of the panel 8, and the droplets of the atomized polishing slurry have lower momentum when forming a spray. This means that when the droplets hit the surface of the panel 8, the reflection ability of the droplets is smaller, and they can fall more accurately on the processed surface, reducing the waste of polishing slurry and lowering costs.

[0043] The clamping bar 704 has a groove 7015 inside, and a slider 7016 is installed inside the groove 7015. A connecting block 703 is fixed to one side of the slider 7016, and springs 7014 are fixed to both ends of one side of the connecting block 703. A clamping block 702 is fixed to one side of the springs 7014, and a mounting base 7017 is installed on one side of the clamping block 702. A cylinder 7018 is movably installed at the middle position of the mounting base 7017. A connecting plate 705 is fixed to the bottom end of one side of the fixing plate 7013. A second gear 707 is installed on one side of one end of the connecting plate 705, and a third gear 708 is fixed to the front end of the second gear 707. A first gear 708 is installed on one side of the second gear 707. Gear 706, one end of the first gear 706 is connected to one side of the connecting plate 705, the bottom end of the connecting block 703 is fixed with a second rack 709, the bottom end of the third gear 708 is mounted with a first rack 701, the bottom end of the first rack 701 is fixed to the top end of the worktable 1, the bottom end of the second rack 709 is provided with a number of teeth, the number of teeth mesh with the first gear 706, two sets of clamping bars 704 are provided, a panel 8 is provided in the middle of the two sets of clamping bars 704, the two sets of clamping bars 704 are symmetrically distributed on both sides of the panel 8, a guide rod is provided on one side of the clamping block 702, and two sets of guide rods are symmetrically distributed on one side of the clamping block 702.

[0044] Reference Figures 1-3 and Figures 9-13As shown: When the polishing brush 6010 is rotating and preparing to polish, the first linear motor 3 is activated to push the clamped panel 8 into contact with the polishing brush 6010 for polishing. As the polishing brush 6010 polishes the panel 8, with the movement of the first linear motor 3, the polishing brush 6010 moves along a straight line on the surface of the panel 8 at both ends. To make the panel 8 more stable during polishing, as the first linear motor 3 pushes the polishing brush 6010 across the surface of the panel 8, the third gear 708 first contacts one end of the surface of the first rack 701. With the movement of the first linear motor 3, the third gear 708 moves on the surface of the first rack 701. Because the third gear 708 meshes with the first rack 701, the third gear 708 rotates. During rotation, the third gear 708, through its engagement with the second gear 707, drives the first gear 706 to rotate. Since the surface of the first gear 706 meshes with the bottom end of the second rack 709... The connecting block 703 at the top of the second rack 709 will move along the position of the polishing brush 6010 to both sides of the panel 8. When the polishing brush 6010 polishes a certain position on the surface of the panel 8, the connecting block 703 will drive the clamping block 702 to move to both sides of the panel 8 at the same polishing position as the polishing brush 6010, clamping the panel 8 for polishing. This makes the panel 8 more stable when the polishing brush 6010 is polishing. The position of the polishing brush 6010 for polishing can be adjusted left and right by the setting of the second linear motor 4. Since the first rack 701 is installed on the worktable 1 and a sufficient distance is reserved in advance between it and the polishing brush 6010, it does not affect the left and right movement of the polishing brush 6010. In addition, a sufficient distance is reserved between the two sets of second racks 709 and the panel 8, so that the left and right movement of the polishing brush 6010 at the bottom of the panel 8 is not affected. This completes the polishing work on both sides of the panel 8, making the polishing of the panel 8 more efficient.

[0045] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
