Description

Technical Field

[0001] The utility model belongs to the technical field of building decoration, and particularly relates to a wood board polishing device for building decoration. Background Technique

[0002] Wood boards are the most common raw materials in the production of various types of furniture. Through the splicing and installation of wood boards, various types of furniture with different functions can be formed. Among them, during the processing, the wood boards need to be polished. Most of the existing wood board polishing devices are exposed, and a large amount of debris and dust will fly during the polishing of the wood boards. A large amount of debris and dust will pollute the working environment and affect the physical health of the staff for a long time. At the same time, the debris and dust adhere to the plates after polishing, and the staff still need to clean them, increasing the workload of the staff.

[0003] The utility model patent with the publication number of CN108381363A discloses a polishing machine for building decoration, which relates to the field of building decoration. It includes a base, a fixed column is fixedly installed on the top of the base, a through hole is opened at the top of the fixed column, and first chutes are opened on both sides of the inner wall of the fixed column. A sliding rod is arranged in the middle of the inner cavity of the fixed column, and the sliding rod is slidably connected with the fixed column through a slider inside the first chute. For this polishing machine for building decoration, by installing an electric push rod to move to the right side of the fixed column, it can drive the second bracket to jack up, so that the movable rod moves upward, adjusting the height of the processing plate, which is beneficial for different staff to adjust the table to a suitable height according to their own height during the polishing process. By opening dust outlet holes on the processing plate, when the device processes wood boards, the wood chips generated during the processing can pass through the dust outlet holes and enter the inside of the dust storage box through the absorption of the fan.

[0004] Although this technology can absorb the debris and dust generated during the processing of wood boards, avoiding the pollution of the working environment by the debris and dust and the impact on the physical health of the staff, this technology cannot position the wood boards, resulting in the easy displacement of the wood boards during the polishing process, affecting the polishing effect and quality of the wood boards.

[0065] Example 1:

[0066] As Figures 1-3 shown, this embodiment provides a wood board polishing device for building decoration, including:

[0067] Base 1;

[0068] Bracket 2, arranged on both sides of the top of the base 1;

[0069] Guide shell 3, arranged on the bracket 2, and the guide shell 3 is a hollow structure;

[0070] Limiting groove 4, arranged on the opposite surfaces of the two guide shells 3, and the limiting groove 4 extends to penetrate the hollow structure of the guide shell 3, and the limiting groove 4 is used to support and limit the wood board;

[0071] Support plate 5, arranged between the two guide shells 3, the top surface of the support plate 5 is flush with the bottom surface of the limiting groove 4 of the guide shell 3, and the support plate 5 is used to support the wood board to be polished;

[0072] Polishing mechanism 9, arranged on the guide shell 3, and used to polish the surface of the wood board to be polished;

[0073] Positioning mechanism 6, arranged in the hollow structure of the guide shell 3, and used to position the wood board to be polished;

[0074] This positioning mechanism 6 includes:

[0075] Frame one 61, arranged on the front and rear sides of the top of the guide shell 3;

[0076] Cylinder 62, arranged on the frame one 61;

[0077] Connecting plate 63, arranged on the piston rod of the cylinder 62;

[0078] Positioning plate 64, arranged between the two connecting plates 63 on the same side, and the positioning plate 64 is located at the upper side inside the hollow structure of the guide shell 3.

[0079] In this technical solution, the base 1 provides a stable foundation for the entire device. The brackets 2 are arranged on both sides of the top of the base 1 to support and stabilize the guide shell 3. The guide shell 3 is installed on the brackets 2 and has a hollow structure to provide support and guidance for the wooden board. The limiting groove 4 is arranged on the opposite side of the guide shell 3 and penetrates through the guide shell 3 to support and limit the position of the wooden board. The support plate 5 is installed between the two guide shells 3, and the top surface is flush with the bottom surface of the limiting groove 4 to provide a support surface for the wooden board. The first frame 61 is installed on the front and rear sides of the top of the guide shell 3 to support the positioning mechanism 6. The cylinder 62 is installed on the first frame 61, and the connecting plate 63 is pushed by the piston rod of the cylinder 62. The connecting plate 63 is connected to the piston rod of the cylinder 62 and moves back and forth with the movement of the cylinder 62. The positioning plate 64 is arranged between the connecting plates 63 and is located on the upper side inside the hollow structure of the guide shell 3 to play a role in accurately positioning the wooden board.

[0080] When it is necessary to polish the surface of the wooden board, the wooden board to be polished is placed on the support plate 5. Both ends of the wooden board enter the hollow structure of the guide shell 3 through the limiting groove 4 and are supported and positioned by the guide shell 3 and the limiting groove 4. The connecting plate 63 and the positioning plate 64 are driven by the cylinder 62 to adjust the position of the positioning plate 64, and the wooden board is accurately positioned in the hollow structure of the guide shell 3, so that the positioning plate 64 fixes the wooden board at a specified position to ensure the accurate positioning of the wooden board in the guide shell 3 and prevent it from moving during the polishing process.

In this way, the positioning of the wooden board is realized, the displacement of the wooden board during the polishing process is prevented, the accuracy and quality of the wooden board during the polishing process are ensured, and the positioning of wooden boards with different thicknesses can be carried out to adapt to different wooden board sizes and polishing requirements.

[0081] Embodiment 2:

[0082] This embodiment provides a wooden board polishing device for building decoration. In addition to including the technical solution of the above embodiment, it also has the following technical features.

[0083] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 shown, in this embodiment, preferably, a sliding mechanism 7 for assisting the movement of the wooden board in the limiting groove 4 is provided inside the hollow structure of the guide shell 3. The sliding mechanism 7 includes:

[0084] There are two groups of the housing 71, and the two groups of the housing 71 are respectively arranged at the lower side inside the guiding housing 3 and the bottom of the positioning plate 64. The two groups of the housing 71 are both located in the hollow structure of the guiding housing 3 and are arranged in an up-and-down manner. Each group of the housing 71 has two, and the two housings 71 are arranged side by side;

[0085] There are multiple support shafts 72, which are evenly spaced along the length direction of the housing 71;

[0086] The pulley 73 is rotatably arranged on the support shaft 72. The pulley 73 is located inside the housing 71, and the upper end of the pulley 73 protrudes from the housing 71. The opposite surfaces of the pulleys 73 in the same guiding housing 3 are arranged.

[0087] In this technical solution, the wooden board to be polished is placed in the hollow structure of the guiding housing 3 through the limiting groove 4, and the wooden board is located on the pulley 73. The pulley 73 rotates on the support shaft 72, and the support shaft 72 maintains the stability of the pulley 73. Since the upper end of the pulley 73 protrudes from the housing 71, the wooden board can rotate smoothly in the guiding housing 3, and the rotation of the pulley 73 reduces the friction, making the movement of the wooden board smoother. When the wooden board needs to be polished, the wooden board is placed into the hollow structure of the guiding housing 3, and the wooden board is located on the pulley 73. Then, the wooden board is pushed, and the movement of the wooden board drives the pulley 73 to rotate. Thus, the pulley 73 assists the wooden board to slide in the guiding housing 3. After the wooden board is moved to a suitable position, the air cylinder 62 is started. The air cylinder 62 drives the connecting plate 63 to drive the positioning plate 64 to move. The positioning plate 64 drives the upper housing 71 to move downward. The housing 71 drives the pulley 73 to move downward through the support shaft 72. The pulley 73 moves to contact with the wooden board. The wooden board is accurately positioned in the hollow structure of the guiding housing 3 through the pulley 73 on the positioning plate 64, so that it remains stable during the polishing process and the polishing effect is improved. After the polishing is completed, the positioning plate 64 is driven by the air cylinder 62 to drive the upper pulley 73 to move away from contact with the wooden board. Then, the polished wooden board is taken out. The rotation of the lower pulley 73 reduces the friction, making the movement of the wooden board smoother. In this way, the movement of the wooden board in the guiding housing 3 is assisted, which is convenient for taking out or placing it and reduces the wear on the wooden board.

[0088] Embodiment 3:

[0089] This embodiment provides a wooden board polishing device for building decoration. In addition to including the technical solution of the above embodiment, it also has the following technical features.

The dust suction hopper 84 is arranged at the bottom of the support plate 5, below the dust outlet slots 81 and communicated with them, and is used to collect and guide the dust. The connecting pipe 85 is connected to the bottom of the dust suction hopper 84 and is responsible for transporting the dust and debris to the negative pressure fan 86. One end of the negative pressure fan 86 is connected to the connecting pipe 85 and the other end is connected to the dust collection box 83, and is used to generate negative pressure and suck the dust and debris into the dust collection box 83.

[0098] During the polishing of the wooden board, the generated dust and debris fall into the dust suction hopper 84 through the dust outlet slots 81. The dust and debris collected by the dust suction hopper 84 are transported to the negative pressure fan 86 through the connecting pipe 85. The negative pressure suction generates negative pressure, sucks the dust and debris in the dust suction hopper 84 into the negative pressure fan 86 through the connecting pipe 85. The negative pressure fan 86 sucks and discharges the dust and debris into the dust collection box 83. The dust collection box 83 is responsible for storing and concentrating these dust and debris to keep the working area clean. After the dust and debris are collected by the dust collection box 83, they can be cleaned regularly to ensure the effective operation of the device and the cleanliness of the operating environment.
