Description

Technical Field

[0001] This utility model relates to the field of acrylic sheet production technology, and in particular to a trimming structure for acrylic sheet processing. Background Technology

[0002] Acrylic sheets are widely used in modern decoration, advertising displays, and industrial manufacturing due to their high transparency, aesthetic appeal, and durability. However, after being cut and shaped, acrylic sheets often have rough and uneven edges with burrs and irregularities. This not only affects the appearance but may also cause scratches during handling or use. Furthermore, rough edges are not conducive to subsequent assembly and installation. Therefore, developing a reasonable and effective acrylic sheet trimming structure is of great significance for improving the quality of acrylic sheets, their safety, and expanding their application range.

[0003] Most existing trimming devices require workers to manually push the acrylic sheet when trimming it. Trimming equipment with a feeding mechanism usually feeds at a straight angle, which may cause the trimming process to be unstable when dealing with irregularly shaped acrylic sheets, and also affect the smoothness of the trimming.

[0004] An existing patent (publication number: CN222681074U) proposes an edge trimming device for acrylic sheets, belonging to the field of acrylic sheet production technology. Its key technical features include a base with a worktable fixedly connected to its top. First, the worktable is fixed to the base. Then, the worktable restricts the range of motion of a sliding component. Next, the sliding component fixes the rotational position of an adjusting component, achieving the movement effect of the adjusting component. Then, the adjusting component adapts to acrylic sheets of different shapes, improving stability during the trimming process. Next, a limiting component adjusts the trimming position of the acrylic sheet. Finally, a dust collection component collects the waste generated during the trimming process. The sliding component fixes the rotational position of the adjusting plate. Then, a positioning pin passes through the adjusting plate and is fixedly connected to the sliding component, thus restricting the rotational position of the adjusting plate. Finally, a fixing bolt passes through the adjusting plate and is threadedly connected to the sliding component, thus fixing the adjusting plate.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, when using existing structures to trim acrylic sheets of different hardness, the replacement of the grinding rod is time-consuming and cumbersome, leading to a longer production cycle. Furthermore, the surface of the acrylic sheet has slight unevenness, which can easily result in uneven trimming.

[0006] Therefore, a trimming structure for acrylic sheet processing is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5The present invention provides the following technical solution:

[0028] A trimming structure for processing acrylic sheets includes a worktable 1, a through hole 2 on the left side inside the worktable 1, a floating adjustable component 3 on the left side of the bottom of the worktable 1, a motor 4 at the bottom of the floating adjustable component 3, a quick-release component 5 at the top of the floating adjustable component 3, the quick-release component 5 being inside the through hole 2, and a polishing rod 6 being bolted to the top of the quick-release component 5.

[0029] The floating adjustable component 3 includes a horizontal block 31, the top of which is bolted to the bottom of the worktable 1. A first sliding groove 32 is provided inside the horizontal block 31. A first slider 33 and a second slider 34 are slidably arranged inside the first sliding groove 32. A pressure spring 35 is connected between the first slider 33 and the second slider 34. The bottom of the first slider 33 is bolted to the top of the motor 4.

[0030] In this embodiment: The trimming structure, with the workbench 1 as the core component, has a pre-drilled through-hole 2 on the left side inside the workbench 1 to provide space for subsequent component installation and operation. Next, the top of the horizontal block 31 in the floating adjustable component 3 is securely bolted to the bottom of the workbench 1 to ensure structural stability. Then, the motor 4 is installed at the bottom of the floating adjustable component 3, allowing power to be transmitted upwards through this component. Afterwards, the quick-release component 5 is installed on top of the floating adjustable component 3 and placed within the through-hole 2, enabling it to operate normally within the hole's range. Finally, the grinding rod 6 is bolted to the top of the quick-release component 5. When the motor 4 starts, power is transmitted sequentially through the floating adjustable component 3 and the quick-release component 5 to the grinding rod 6, causing it to rotate and trim the acrylic sheet. The floating adjustable component 3 includes the horizontal block 31, the first... The system includes a sliding groove 32, a first slider 33, a second slider 34, and a pressure spring 35. The top of the horizontal block 31 is bolted to the bottom of the worktable 1, which serves to fix the floating adjustable component 3. The first slider 33 and the second slider 34 can slide in the first sliding groove 32 inside the horizontal block 31. They are connected by the pressure spring 35. The bottom of the first slider 33 is bolted to the top of the motor 4. When the motor 4 vibrates during operation, or when the grinding rod 6 encounters changes in resistance while trimming the acrylic sheet, the first slider 33 will slide in the first sliding groove 32, compressing or stretching the pressure spring 35. The extension and contraction of the pressure spring 35 can buffer vibration and adjust pressure, ensuring the stability and adaptability of the grinding rod 6 in contact with the acrylic sheet during the trimming process, and avoiding damage to the sheet due to excessive pressure or poor trimming effect due to insufficient pressure.

[0031] Specifically, such as Figure 3 As shown, the quick-release assembly 5 includes a connecting block 51. The output shaft of the motor 4 extends to the top of the first slider 33 and is bolted to the bottom of the connecting block 51. A mating groove 52 is provided inside the connecting block 51.

[0032] Specifically, such as Figure 3 As shown, a first strong magnet 53 is provided at the bottom of the docking groove 52, and a docking block 54 is slidably disposed inside the docking groove 52.

[0033] Specifically, such as Figure 3 As shown, a second strong magnet 55 is provided at the bottom inside the docking block 54, and the top of the docking block 54 is bolted to the bottom of the polishing rod 6.

[0034] In this embodiment: In the trimming structure, the output axis of the motor 4 extends upward, passes through the top of the first slider 33, and is bolted to the bottom of the connecting block 51, thereby ensuring that the power of the motor 4 is directly transmitted to the connecting block 51. The connecting block 51 has a docking groove 52 for docking with other components. A first strong magnet 53 is installed at the bottom of the groove. At the same time, a docking block 54 is prepared, with a second strong magnet 55 installed at the bottom inside. The bottom of the grinding rod 6 is bolted to the top of the docking block 54 as one piece. When installing the grinding rod 6, the docking block 54 is aligned with the docking groove 52 and inserted. The strong attraction between the first strong magnet 53 and the second strong magnet 55 makes the docking block 54 firmly fixed in the docking groove 52, thereby realizing the connection between the grinding rod 6 and the power output of the motor 4. When the grinding rod 6 needs to be replaced after a period of use, a certain external force is applied to overcome the magnetic force between the two strong magnets, and the docking block 54 can be pulled out, quickly completing the disassembly of the grinding rod 6.

[0035] Specifically, such as Figure 2 As shown, a pressure adjusting pin 7 is threadedly connected to the left side of the inside of the horizontal block 31, and the right side of the pressure adjusting pin 7 contacts the left side of the second slider 34.

[0036] Specifically, such as Figure 2 As shown, the left side of the pressure regulating pin 7 extends to the left side of the horizontal block 31 and is bolted with the turntable 8.

[0037] In this embodiment: During the acrylic sheet trimming process, the pressure of the floating adjustable component 3 needs to be adjusted to accommodate sheets of different thicknesses and hardnesses. In this component, a pressure adjusting pin 7 is threadedly connected to the left side of the horizontal block 31, allowing it to move left and right within the horizontal block 31. The right side of the pressure adjusting pin 7 contacts the left side of the second slider 34, and the left side extends to the left side of the horizontal block 31 and is bolted to the turntable 8. When encountering a thicker or harder acrylic sheet, the operator rotates the turntable 8 clockwise, causing the pressure adjusting pin 7 to move to the right within the horizontal block 31. The pressure adjusting pin 7 pushes the second slider 34. 4. Slide to the right within the first sliding groove 32 to compress the pressure spring 35 between the first slider 33 and the second slider 34. After the pressure spring 35 is compressed, the pressure supplied to the first slider 33 increases, which in turn increases the pressure on the acrylic sheet by the motor 4 and the polishing rod 6 connected to the first slider 33, ensuring the trimming effect. Conversely, when encountering a thinner or softer acrylic sheet, the operator rotates the turntable 8 counterclockwise to move the pressure adjusting pin 7 to the left, reducing the compression of the pressure spring 35 and the pressure of the polishing rod 6 on the acrylic sheet, thus avoiding damage to the sheet.

[0038] Specifically, such as Figure 1 , Figure 5 As shown, a guide plate 9 is provided on the left side of the top of the workbench 1. A notch 10 is provided on the surface of the guide plate 9, and the grinding rod 6 is located inside the notch 10.

[0039] Specifically, such as Figure 4 , Figure 5 As shown, two second sliding grooves 11 are provided on the left side inside the worktable 1. A third slider 12 is slidably arranged inside the second sliding groove 11. The tops of the two third sliders 12 are respectively bolted to the front and rear sides of the bottom of the guide plate 9. The front and rear sides inside the guide plate 9 are threaded with fixing pins 13. The bottom of the fixing pins 13 contacts the top of the worktable 1.

[0040] In this embodiment: a notch 10 is made on the surface of the guide plate 9, and the grinding rod 6 is placed in the notch 10. During trimming, the operator can move the acrylic plate along the guide plate 9 so that the part to be trimmed accurately contacts the rotating grinding rod 6. In order to allow the guide plate 9 to adapt to different grinding depths of the acrylic plate and thus adjust the protrusion distance of the grinding rod 6, two second sliding grooves 11 are made on the left side inside the worktable 1. Each groove is equipped with a sliding third slider 12. The tops of the two third sliders 12 are respectively bolted to the front and rear sides of the bottom of the guide plate 9. The guide plate 9 can then slide left and right in the second sliding grooves 11 through the third sliders 12. After the position of the guide plate 9 is adjusted and the protrusion distance of the grinding rod 6 is adjusted, fixing pins 13 are threadedly connected to the front and rear sides inside the guide plate 9. The fixing pins 13 are tightened so that the bottom of the guide plate 9 is in close contact with the top of the worktable 1, thereby fixing the guide plate 9 and preventing it from moving during the trimming process.

[0041] Working Principle: This trimming structure is based on a workbench 1, with a through hole 2 on its left side. The top of the horizontal block 31 of the floating adjustable component 3 is bolted to the bottom of the workbench 1. The motor 4 is installed at the bottom of the floating adjustable component 3, and the quick-release component 5 is installed on top of the floating adjustable component 3 and placed inside the through hole 2. The grinding rod 6 is bolted to the top of the quick-release component 5. After the motor 4 starts, the power is transmitted to the grinding rod 6 through the floating adjustable component 3 and the quick-release component 5, causing it to rotate. The horizontal block 31 of the floating adjustable component 3 has a first sliding groove 32, in which the first slider 33 and the second slider 34 can slide and are connected by a pressure spring 35. The bottom of the first slider 33 is bolted to the top of the motor 4. When the motor 4 vibrates or the grinding rod 6 encounters resistance, the first slider... The sliding mechanism 33 causes the pressure spring 35 to extend and retract, serving as a buffer and pressure regulator. The grinding rod 6 can be quickly replaced via the quick-release assembly 5. The connecting block 51 connected to the output shaft of the motor 4 has a docking groove 52 with a first strong magnet 53. The bottom docking block 54 of the grinding rod 6 has a second strong magnet 55. They are connected by magnetic force, and can be disassembled by applying external force to overcome the magnetic force. The floating adjustable assembly 3 can also adjust the pressure by rotating the turntable 8 connected to the pressure regulating pin 7 to adapt to different materials. During trimming, the notch 10 on the surface of the guide plate 9 accommodates the grinding rod 6. The operator moves the acrylic plate along it to trim. The grinding depth can be adjusted by sliding the guide plate 9 left and right through the second sliding groove 11 and the third slider 12 in the worktable 1. After adjustment, tighten the fixing pin 13 to fix the guide plate 9.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
