[0017] 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.

[0018] Please see Figure 1-6 As shown in the figure, a bamboo and wood product polishing device according to an embodiment of the present invention includes a machine base 1. A clamping unit 2 for fixing bamboo and wood products is provided on the top surface of the machine base 1. A stand 3 is provided on the top surface of the machine base 1 at the position corresponding to the clamping unit 2. A polishing unit 30 is provided on the top of the stand 3 at the position corresponding to the clamping unit 2. A dust collection unit 4 is provided on the inner side of the stand 3 at the position corresponding to the polishing unit 30. A power supply module 31 is fixedly provided on the rear side of the stand 3. The power supply module 31 is electrically connected to the polishing unit 30 through a wire 32. A first guide sleeve 33 and a second guide sleeve 34 are respectively provided on the stand 3. The wire 32 passes through the first guide sleeve 33 and the second guide sleeve 34 in sequence and is connected to the polishing unit 30. A gravity block 35 is sleeved on the part of the wire 32 between the first guide sleeve 33 and the power supply module 31.

[0019] During use, the clamping unit 2 securely fixes the bamboo and wood materials, replacing manual gripping and solving the burden of arms dangling in the air and needing to hold the materials tightly in traditional operations, while also avoiding the safety hazards caused by materials detaching due to friction. The grinding unit 30 adopts a handheld design, allowing workers to actively pull the grinder to contact the materials for grinding, making operation flexible. The first and second guide sleeves 34 provide directional guidance for the wire 32, and the reserved length between the wire 32 and the power supply module 31 meets the grinding machine's stretching requirements while preventing the wire 32 from becoming tangled or messy. The gravity block 35 uses its own weight to automatically pull down the wire 32 after the grinder is used, causing the grinder to quickly return to its original position without manual repositioning, improving operational convenience. The dust collection unit 4 collects dust in a timely manner, improving the working environment and reducing health risks. The power supply module 31 adopts existing technology products commonly used in the field, mainly used to provide stable power support for the grinding unit 30. Its specific structure and working principle are well known to those skilled in the art. For example, a switching power supply of Model Mean Well LRS-100-24, a DC power supply of Model Delta PMT-24V100W1AA, or a battery suitable for powering small equipment (such as a 12V / 20Ah lead-acid battery) can be selected. The power supply function can be realized by electrically connecting it to the grinding unit 30 through the wire 32. It will not be described in detail here.

[0020] The conductor 32 is covered by a protective sleeve 36, and the gravity block 35 is fitted on the outside of the protective sleeve 36.

[0021] During use, the protective sleeve 36 outside the wire 32 can enhance the protection of the wire 32, prevent the wire 32 from being worn or scratched during equipment operation, and extend its service life; the outer wall of the protective sleeve 36 is smooth, reducing the frictional resistance with the first and second guide sleeves 34, ensuring smooth pulling and retraction when the grinder is stretched and reset, and improving the operating feel.

[0022] The lower opening end of the second guide sleeve 34 is connected to a receiving kit 37, the receiving kit 37 is formed with a receiving groove 38, the top of the grinding unit 30 is formed with a receiving end that matches the receiving groove 38, and the outer opening end of the receiving groove 38 is provided with a cushioning pad 39.

[0023] In use, the receiving groove 38 of the receiving kit 37 is adapted to the receiving end of the grinder. In the initial state, the grinder can be stably limited in the receiving groove 38 to prevent it from shaking randomly. The receiving structure guides the grinder to reset, ensuring accurate reset and improving the continuity of operation.

[0024] The polishing unit 30 is a handheld polisher.

[0025] When in use, the handheld sander can be actively held and pulled by the operator to flexibly adjust the sanding angle and intensity, adapting to the sanding needs of different parts of bamboo and wood materials (such as curved surfaces and edges); with the automatic reset function of the gravity block 35, there is no need to manually place it after use, reducing operation steps, reducing workload, and improving efficiency; see the attached instruction manual. Figure 5 This is a schematic diagram of another embodiment of the grinding unit of this utility model. The grinding unit in this device has two embodiments: Embodiment 1 is described in the appendix of the instruction manual. Figure 1-2 The machine adopts a horizontally downward-facing grinding disc structure, which is well-suited for sanding flat bamboo and wood products. When sanding bamboo boards, flat bamboo components, etc., the horizontally downward-facing grinding disc can naturally fit the surface of the workpiece. The operator can hold the vertical part more smoothly and apply force more evenly. This allows the sanding force to be applied evenly to the workpiece, effectively avoiding the problem of over-sanding or under-sanding in some areas due to the tilt of the grinding disc. It improves the flatness and consistency of the surface sanding. It is especially suitable for standardized sanding operations of batch bamboo flat products, which can reduce the operation of repeatedly adjusting the angle manually and improve sanding efficiency. Example 2 (see attached instruction manual) Figure 5 The device adopts a structure similar to existing angle grinders, with the grinding disc located on the side. Its advantage lies in adapting to the complex contour grinding needs of bamboo and wood products. For bamboo irregular parts (such as bamboo carvings and bamboo curved decorative parts) and workpieces with edge and corner structures, the side grinding disc can flexibly reach into narrow areas and fit curved surfaces and edges. By adjusting the grip posture, the operator can accurately grind the side edges, corners, and curved surfaces of bamboo products, making up for the limitations of the flat grinding structure in handling irregular parts, expanding the device's adaptability to diverse bamboo and wood products, and achieving full-scene grinding coverage from flat surfaces to complex contours. The handheld sanders used are existing technology products. Their design needs to meet the requirements of being small and lightweight, so that operators can easily hold them with one hand for flexible sanding operations. These sanders are generally equipped with replaceable sanding heads and have multiple speed adjustment functions to adapt to the sanding needs of bamboo and wood products of different materials. For example, the Dongcheng S1B-FF02-125 angle grinder can be selected. It weighs about 1.1kg, is small in size and has stable power, and is suitable for fine sanding of the edges, corners and curved surfaces of bamboo and wood products. The aforementioned handheld grinder, thanks to its lightweight nature, can be temporarily placed using the housing kit of this device, while also meeting the flexibility requirements of operators for handheld grinding.

[0026] The clamping unit 2 includes a base 20, a fixed clamp 21 is mounted on the top surface of the base 20, a movable clamp 22 that cooperates with the fixed clamp 21 is slidably disposed on the upper surface of the base 20, a guide groove 23 is formed on the base 20, a positioning screw 24 is rotatably disposed in the guide groove 23, a guide slider 25 that is adapted to the guide groove 23 is formed on the lower surface of the movable clamp 22, and a threaded through hole 26 that is adapted to the positioning screw 24 is formed on the guide slider 25.

[0027] When in use, the fixed clamp 21 and the movable clamp 22 cooperate, and through the sliding structure of the positioning screw 24 and the guide slider 25, the clamping distance can be precisely adjusted to firmly fix bamboo and wood materials of different sizes, ensuring that the materials do not shift during sanding. This provides a stable foundation for the operation of the handheld sander and avoids sanding deviations caused by material shaking. It replaces manual holding and solves the problem of the arm being suspended in the air and having to resist friction to hold the material in traditional operation, greatly reducing the workload.

[0028] One end of the positioning screw 24 extends through to the front of the base 20 and is connected to a rotating rocker arm 27.

[0029] When in use, rotating the rocker arm 27 makes it easier to rotate the positioning screw 24, and the operator can easily adjust the position of the movable clamp 22 to clamp the material. The operation is convenient, further reducing the operator's burden and improving work efficiency.

[0030] Both the fixed clamp 21 and the movable clamp 22 are provided with detachable clamping blocks 28 on their opposing sides.

[0031] When in use, the detachable clamping block 28 can be replaced according to the shape (such as round or irregular shape) or material (such as fragile bamboo strips) of the bamboo and wood materials to ensure that different types of materials can be tightly clamped, avoid slipping during sanding, and provide a guarantee for the stable operation of the handheld sander. At the same time, the clamping block 28 can be replaced separately after wear, reducing maintenance costs. The detachable connection between the fixed clamp 21 and the movable clamp 22 and the clamping block 28 adopts conventional fastener installation methods in the field, such as existing technologies such as bolt and nut mating and screw and threaded hole mating. Specifically, threaded holes are pre-set on the opposite sides of the fixed clamp 21 and the movable clamp 22, and through holes are opened at the corresponding positions of the clamping block 28. Fasteners (such as bolts or screws) pass through the through holes and are screwed into the threaded holes to complete the fixing of the clamping block 28. When disassembling, the clamping block 28 can be removed by loosening the fasteners. Its connection structure is simple and is a commonly used technology in the industry, and will not be described in detail here.

[0032] The base 20 has two fixed ear plates 29 formed on its left and right sides, and the two fixed ear plates 29 are equipped with fasteners.

[0033] When in use, the fixed ear plate 29 and the fastener can firmly fix the clamping unit 2 on the equipment base 1, preventing the clamping unit 2 from shifting due to vibration during grinding, ensuring the stability of the material fixation, and indirectly ensuring the safety of the operator (no need to worry about accidents caused by the shaking of the material or the clamping unit 2).

[0034] The vacuuming unit 4 includes a suction cover 40, a suction port 41 formed at the bottom of the suction cover 40, and a suction pipe 42 connected to the top of the suction cover 40, which is connected and cooperates with an external vacuuming mechanism.

[0035] During use, the suction hood 40 is fixedly connected to the stand 3 via a fixing rod. The suction port 41 of the suction hood 40 is close to the grinding area, which can efficiently collect the dust generated during grinding and prevent the dust from affecting the operator's vision or being inhaled. The suction pipe 42 transports the dust to the external dust collection mechanism, keeping the working environment clean and reducing the dust pollution to the grinder and the wire 32, thereby indirectly ensuring the smooth operation and service life of the equipment. The suction tube 42 is connected to the external vacuuming mechanism using a conventional detachable connection method in the art, such as through snap-fit, threaded connection, or sleeve connection, which facilitates disassembly and maintenance. The external vacuuming mechanism can be a commonly used product in the art, such as an industrial vacuum cleaner (e.g., the Haier ZL1205G industrial vacuum cleaner or the Midea C7 vacuum cleaner). Its specific structure and working principle are well known to those skilled in the art; it mainly achieves dust suction and collection by generating negative pressure, and will not be elaborated further here. The suction hood 40 of the dust collection unit 4 can be connected to the stand 3 in various ways to adapt to different polishing scenarios: In the first embodiment, refer to the appendix of the specification. Figure 1-2 The suction cover 40 is fixedly connected to the stand 3 by a fixing rod, and its position and the angle of the suction port 41 remain constant, making it suitable for grinding operations on a fixed area; in the second embodiment, refer to the appendix of the instruction manual. Figure 6 An adjustment plate is provided at the rear end of the suction cover 40, and an adjustment ear plate is provided on the inner side of the upright frame 3. The adjustment plate and the adjustment ear plate are rotatably connected, and fasteners are provided on the adjustment ear plate. By loosening the fasteners, the adjustment plate can be rotated to change the angle of the suction cover 40, thereby adjusting the orientation of the suction port 41. After adjusting to a suitable angle, the adjustment plate and the adjustment ear plate are fixed by the fasteners, so as to adapt to the sanding needs of different parts of bamboo and wood products and improve the targeting of dust collection.

[0036] The specific working process of this utility model is as follows: During operation, the positioning screw 24 is first rotated by rotating the rocker arm 27, causing the movable clamp 22 to slide along the guide groove 23. The distance between the fixed clamp 21 and the movable clamp 22 is adjusted, and the bamboo and wood material is placed between them and clamped (the appropriate clamping block 28 can be replaced according to the material; the clamping unit 2 is fixed to the equipment base 1 by the fixed ear plate 29 and fasteners); the operator holds the handheld grinder (initially located in the receiving groove 38 of the receiving kit 37) and pulls it downwards, using the motor-driven grinding head to grind the fixed material. During the process, the first and second guide sleeves 34 guide the wire 32, and the protective sleeve 36 prevents the wire 32 from being stretched and damaged and ensures smooth pulling. The reserved length of the wire 32 meets the stretching requirements. The dust generated by grinding enters the suction pipe 42 through the suction port 41 of the suction cover 40 and is collected by the external dust collection mechanism. After grinding is completed, the staff releases the grinder, and the gravity block 35 pulls down the wire 32 due to its own weight, which drives the grinder to reset along the guide structure. The buffer pad 39 reduces the impact during reset, so that the grinder is re-stable in the receiving groove 38. Finally, the clamping unit 2 is released and the material is removed.

[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
