Description

Technical Field

[0001] This utility model belongs to the field of acrylic sheet processing technology, specifically relating to a device for polishing the surface of extra-thick acrylic sheets. Background Technology

[0002] Acrylic sheet (polymethyl methacrylate) is a common transparent plastic with high light transmittance, weather resistance, and easy processing. It is widely used in advertising signs, display racks, lamps, furniture, handicrafts and other fields. Polishing is a very important step in its processing.

[0003] In the prior art, such as the polishing device for engineered stone slabs with application number 202122516408.2, a frame is composed of two L-shaped plates and several horizontal plates installed on the front and rear sides between the two L-shaped plates. In this utility model, a side clamping mechanism is set up to cooperate with the bearing plate and the receiving plate. The bearing plate supports the engineered stone slab, and the gravity of the engineered stone slab drives the guide rod to move downward. The wedge block is driven to move through the support plate and the connecting rod.

[0004] In the above, the wedge block and the slab stone are locked together to keep the position of the slab stone relatively fixed, which ensures the polishing effect of the slab stone to a certain extent. However, after reading the technical solution, it is found that the wedge block responsible for clamping and stabilizing can only allow the slab stone to be polished in a fixed position. Moreover, the distance between the slab stone and the polishing part needs to be adjusted each time the polishing is carried out. Multiple adjustments will result in poor polishing effect and cannot meet the polishing precision requirements of the slab stone. Utility Model Content

[0005] The purpose of this invention is to provide a device for polishing the surface of extra-thick acrylic sheets, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes an L-shaped plate, with a base plate on the upper surface of the L-shaped plate. A lifting assembly is fitted onto the base plate. The lifting assembly includes a flat frame, with a through-hole shaft at one end of the flat frame. A grinding disc is fixedly connected to the bottom of the through-hole shaft, and a drive motor is adapted to be installed at the top of the through-hole shaft. A lifting and pressing assembly is fitted onto the flat frame, including a lifting and pressing rod fixed to the flat frame. A vertical spring is fitted to the bottom of the lifting and pressing rod, and a sliding column is provided at the bottom of the vertical spring. A lifting plate is pressed against the lower surface of the sliding column, and a plate is placed on the side of the lifting plate.

[0007] In a preferred embodiment of this utility model, a rotating bearing is rotatably sleeved in the middle of the lifting plate, a support kit is provided on the end face of the rotating bearing, and the lifting plate is fitted with an alignment component. An adapter seat is slidably fitted on the side of the sliding column, and the bottom of the adapter seat is fixed to the base plate.

[0008] In a preferred embodiment of this invention, the alignment component includes a disc fixed to one end of the lifting plate, and an annular track is provided on the inner side of the disc.

[0009] As a preferred embodiment of this utility model, the inner wall surface of the annular track is slidably fitted with a support rod, and a spider frame is adapted to be installed on the side of the support rod.

[0010] As a preferred embodiment of this utility model, a universal ball is installed at the bottom of the plate, and the surface of the universal ball is movable in conjunction with the spider frame.

[0011] In a preferred embodiment of this utility model, the spider frame is composed of multiple curved straight rods, and the bottom of the spider frame is set to a flat shape.

[0012] In a preferred embodiment of this utility model, a hair dryer is placed on the side of the plate, and the bottom of the hair dryer is adapted to be installed on the L-shaped plate.

[0013] As a preferred embodiment of this utility model, the lifting assembly further includes a collar, the side of which is fixed to the flat frame, and a screw is threadedly connected to the inner side of the collar. A power motor is adapted to be installed on the top of the screw, the surface of which is fixed to the L-shaped plate, and the bottom of the screw is embedded in the base plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the cooperation of the base plate and the lifting component, the flat frame can stably place the insert shaft and grinding disc to achieve the polishing of the board. In addition, the cooperation of the lifting rod and the vertical spring can push the sliding column down to lift the board through the elastic force of the vertical spring, causing the board placed on the side plate of the lifting plate to be lifted. In this process, the vertical spring is first compressed by the lifting rod, and the compression generates elastic force. According to the basic principle of action and reaction force, the bottom end face of the vertical spring will generate a rebound force (i.e., the downward pressure acting on the lifting plate). Since the vertical spring is compressed first and then pressed down, the lifting of the board is slightly delayed after the pressing of the lifting rod. Therefore, during the polishing operation, the grinding disc will rotate first and the board will be lifted later. This method allows the board to repeatedly contact the grinding disc, making the polishing effect smooth and stable, avoiding the grinding disc from cutting too deeply and leaving pits on the surface of the board, and improving the polishing precision.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This utility model embodiment proposes a device for polishing the surface of extra-thick acrylic sheets, including an L-shaped plate 1; exemplarily, such as... Figures 1-3 As shown.

[0023] The upper surface of the L-shaped plate 1 is provided with a base plate 2. The base plate 2 is fitted with a lifting assembly 3. The lifting assembly 3 includes a flat frame 34. One end of the flat frame 34 is provided with a through shaft 35. The bottom of the through shaft 35 is fixedly connected to a grinding disc 36, and the top of the through shaft 35 is fitted with a drive motor 37. The flat frame 34 is fitted with a lifting and pressing assembly 4. The lifting and pressing assembly 4 includes a lifting and pressing rod 41 fixed to the flat frame 34. The bottom of the lifting and pressing rod 41 is fitted with a vertical spring 42. The bottom of the vertical spring 42 is provided with a sliding column 43. The lower surface of the sliding column 43 presses against a lifting plate 45. A plate 56 is placed on the side of the lifting plate 45.

[0024] A rotating bearing 46 is rotatably sleeved in the middle of the lifting plate 45. A support kit 47 is provided on the end face of the rotating bearing 46. The lifting plate 45 is equipped with an alignment component 5. An adapter seat 44 is slidably fitted on the side of the sliding column 43. The bottom of the adapter seat 44 is fixed to the base plate 2.

[0025] The alignment component 5 includes a disc 51 fixed to one end of the lifting plate 45, and an annular track 52 is provided on the inner side of the disc 51.

[0026] Specifically, through the cooperation of the base plate 2 and the lifting assembly 3, the flat frame 34 can stably place the insert shaft 35 and the grinding disc 36 to polish the plate 56. The cooperation of the lifting rod 41 and the vertical spring 42 allows the sliding column 43 to press down on the lifting plate 45 through the elastic force of the vertical spring 42, causing the plate 56 placed on the side plate of the lifting plate 45 to be lifted. During this process, the vertical spring 42 is first compressed by the lifting rod 41, generating elastic force. This compression utilizes the basic principle of action and reaction forces. The bottom end face of the vertical spring 42 will generate a rebound force (i.e., the downward pressure acting on the lifting plate 45). Since the vertical spring 42 is compressed first and then pressed down, the lifting of the plate 56 is slightly delayed after the pressing of the lifting rod 41. As a result, during the polishing operation, you will see that the grinding disc 36 rotates first and the plate 56 is lifted up later. This method will allow the plate 56 to repeatedly contact the grinding disc 36, making the polishing effect smooth and stable, avoiding the grinding disc 36 from cutting too deeply and leaving pits on the surface of the plate 56, and improving the polishing precision.

[0027] The cooperation between the support kit 47 and the rotating bearing 46 makes the lifting plate 45 more stable. The adapter seat 44 on the side of the sliding column 43 allows the sliding column 43 to always fall vertically with a straight falling trajectory. The adapter seat 44 can serve as a support to provide long-term stability for the sliding column 43. The annular track 52 on the inner side of the disc 51 provides support at the bottom when the plate 56 comes into contact with the continuously rotating grinding disc 36, reducing the deviation of the plate 56 during polishing.

[0028] The inner wall surface of the annular track 52 is slidably fitted with a support rod 53; for example, such as Figures 2-4 As shown.

[0029] A spider-shaped frame 54 is fitted to the side of the support rod 53.

[0030] A swivel ball 55 is installed at the bottom of the plate 56, and the surface of the swivel ball 55 is movable in conjunction with the spider frame 54.

[0031] The spider-shaped frame 54 is composed of multiple curved straight rods, and the bottom of the spider-shaped frame 54 is set to a flat shape.

[0032] Specifically, through the sliding engagement of the support rod 53 and the annular track 52, the downward thrust generated during the polishing of the plate 56 is offset by this sliding force. The polished surface of the plate 56 is always in contact with the bottom of the grinding disc 36, resulting in a more durable polished surface and higher polishing precision. Furthermore, the adaptive installation of the spider frame 54 allows its unique spider leg structure to better distribute the downward thrust of the plate 56. Compared to the internal clamping structure of the wedge block, this force-sharing structure better ensures the balance of the plate 56, which is beneficial to improving polishing precision. Additionally, the installation of the universal ball 55 on the top of the spider frame 54 provides spherical support for the plate 56, thereby providing a better support plane for the polishing of the plate 56.

[0033] A hair dryer 6 is placed beside the plate 56; for example, such as Figures 3-4 As shown.

[0034] The bottom of the hair dryer 6 is fitted and installed to fit the L-shaped plate 1.

[0035] The lifting assembly 3 also includes a collar 33, the side of which is fixed to the flat frame 34, and the inner side of the collar 33 is threaded with a screw 31. A power motor 32 is adapted to be installed on the top of the screw 31, the surface of the power motor 32 is fixed to the L-shaped plate 1, and the bottom of the screw 31 is embedded in the base plate 2.

[0036] Specifically, the combination of the blower 6 and the plate 56 allows the debris from the plate 56 after polishing to be blown away in time, avoiding affecting the polishing accuracy. The combination of the power motor 32, the screw 31 and the collar 33 allows the collar 33 to move along the surface of the screw 31, facilitating direct contact between the grinding disc 36 and the plate 56.

[0037] Working principle: First, install the plate 56 and the universal ball 55, then connect the universal ball 55 to the spider frame 54. The bottom end face of the spider frame 54 is fitted with the support rod 53, so that the support rod 53 slides in conjunction with the annular track 52 opened on the inner side of the disc 51.

[0038] Then, the power motor 32 is started, which drives the screw 31 to rotate. This further causes the collar 33 to move along the surface of the screw 31 and the flat frame 34 to move synchronously. The lifting rod 41 set at the bottom of the flat frame 34 first presses against the vertical spring 42. The vertical spring 42 is first compressed and then stretched to push, causing the sliding column 43 to slide vertically along the inner side of the adapter seat 44. Then the sliding column 43 continues to move down, causing one end of the lifting plate 45 to press down. Under the support of the rotating bearing 46 and the support kit 47, the other end of the lifting plate 45 lifts the plate 56, causing the plate 56 to rise and contact the lower surface of the grinding disc 36.

[0039] At the same time, the drive motor 37 is turned on, causing the grinding disc 36 to rotate continuously. When the grinding disc 36 comes into contact with the plate 56, the plate 56 will deviate downwards. The spider frame 54 set at the bottom of the plate 56 evenly distributes this force, keeping the plate 56 in a fixed position and achieving contact polishing with the grinding disc 36.
