Description

Technical Field

[0001] This utility model belongs to the field of wood door processing technology, and more specifically, it relates to a door surface treatment device for wood door processing. Background Technology

[0002] In the field of wooden door processing technology, the surface treatment of the door surface (such as deburring, sanding and polishing) is a key process that affects the quality of finished wooden doors, directly determining the flatness of the wooden door's appearance, the adhesion of subsequent paint, and the overall aesthetics.

[0003] While existing door surface treatment devices for wooden door processing have improved efficiency, they still have some problems: Asynchronous double-sided sanding: Some devices can only sand one side, requiring the wood to be flipped for secondary processing, making it difficult to control processing precision; Incomplete dust collection: Traditional dust collection structures are poorly designed, failing to cover the entire sanding area, leading to dust accumulation and affecting the sanding effect. Therefore, there is an urgent need for a door surface treatment device that can efficiently and accurately complete double-sided sanding of wooden doors while also possessing good dust collection capabilities. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a door surface treatment device for wooden door processing, which is achieved by the following specific technical means:

[0005] A door surface treatment device for wooden door processing includes a base plate, a connecting plate fixedly connected to one end of the base plate, a bracket fixedly installed on the upper end of the connecting plate, two mounting plates arranged vertically within the bracket, a sandpaper roller rotatably mounted in each mounting plate, a drive motor for driving the sandpaper roller to rotate fixedly mounted on each mounting plate, a cylinder fixedly mounted at the top center of the bracket, the bottom end of the cylinder's telescopic rod fixedly connected to the center of the upper mounting plate for adjusting the distance between the two sandpaper rollers, a suction pipe fixedly mounted on the rear side of each mounting plate, a plurality of suction heads fixedly mounted equidistantly on each suction pipe, and a connecting hose connected to the side end of each suction pipe.

[0006] Furthermore, the vacuum heads on the lower vacuum tube are distributed vertically to the support direction and have their openings facing upwards, while the vacuum heads on the upper vacuum tube are inclined and have their openings facing downwards. Each of the vacuum heads is trumpet-shaped.

[0007] Furthermore, each of the connecting hoses is fixedly connected to a connecting flange for connecting to the air inlet port of the vacuum cleaner.

[0008] Furthermore, two guide rods are fixedly installed at the upper end of the mounting plate, each guide rod movably passing through the bracket to limit the movement of the mounting plate.

[0009] Furthermore, side plates are fixedly installed on both sides of the upper end of the base plate, and several rotating shafts are equidistantly installed between the two side plates.

[0010] Furthermore, fixing plates are fixedly installed on both sides of the upper end of the connecting plate, and several rotating shafts are equidistantly mounted between the two fixing plates.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This door surface processing device for wooden doors uses two vertically distributed mounting plates. Each mounting plate is equipped with a sandpaper roller and a drive motor. The drive motor can drive the sandpaper roller to rotate synchronously at high speed, which can complete the deburring and sanding of the upper and lower surfaces of the wooden door in one go, without the need for manual flipping, shortening processing time and improving processing efficiency. At the same time, it avoids the errors caused by secondary positioning, ensuring that the sanding force and flatness of the upper and lower surfaces of the door are consistent, effectively guaranteeing processing accuracy. The cylinder at the top of the bracket is fixedly connected to the upper mounting plate. The extension and retraction of the cylinder's telescopic rod can drive the upper mounting plate to rise and fall vertically, thereby adjusting the distance between the upper and lower sandpaper rollers, which can adapt to the processing needs of wooden door surfaces of different thicknesses.

[0013] 2. The upper and lower suction pipes use trumpet-shaped suction heads, arranged upwards and downwards respectively, to expand the suction range, accurately cover the sanding area, effectively adsorb sawdust and dust, prevent accumulation from affecting the sanding effect, and connect the hose to the external vacuum equipment to ensure real-time dust removal, improve the working environment, and protect the health of operators. A rotatable shaft is set on the base plate, which, together with the side plate limit, allows the wood board to slide smoothly during feeding, reduces frictional resistance, and avoids surface scratches. A second shaft on the fixed plate supports and transports the sanded wood board, preventing the wood board from colliding with the suction head below and ensuring the stability of the processing.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a door surface treatment device for wooden door processing, including a base plate 1. A connecting plate 2 is fixedly connected to one end of the base plate 1. A bracket 3 is fixedly installed on the upper end of the connecting plate 2. Two mounting plates 4 are arranged inside the bracket 3. The two mounting plates 4 are distributed vertically. A sandpaper roller 41 is rotatably installed in each mounting plate 4. A drive motor 42 for driving the sandpaper roller 41 to rotate is fixedly installed on each mounting plate 4. A cylinder 5 is fixedly installed at the middle of the top of the bracket 3. The bottom end of the telescopic rod of the cylinder 5 is fixedly connected to the middle of the upper mounting plate 4 for adjusting the distance between the two sandpaper rollers 41. A dust suction pipe 6 is fixedly installed on the rear side of each mounting plate 4. A plurality of dust suction heads 61 are fixedly installed at equal intervals on each dust suction pipe 6. A connecting hose 62 is connected to the side end of each dust suction pipe 6.

[0026] Furthermore, the suction heads 61 located on the lower suction pipe 6 are distributed vertically to the support 3 and have their openings facing upwards. The suction heads 61 located on the upper suction pipe 6 are inclined and have their openings facing downwards. Each suction head 61 is trumpet-shaped, which expands the suction range, improves the efficiency of impurity adsorption, and ensures that there is no dust accumulation in the sanding area. This does not affect the sanding effect of the sandpaper roller 41 and also protects the health of the operator.

[0027] Furthermore, each of the connecting hoses 62 is fixedly connected to a connecting flange 63 for communicating with the air inlet port of the vacuum cleaner. The connecting hose 62 is designed as a hose and has a certain degree of flexibility to avoid motion interference when adjusting the distance between the two sandpaper rollers 41.

[0028] Furthermore, two guide rods 51 are fixedly installed on the upper end of the mounting plate 4. Each guide rod 51 movably passes through the bracket 3 to limit the movement of the mounting plate 4 and ensure that the mounting plate 4 moves stably in the vertical direction.

[0029] Furthermore, side plates 11 are fixedly installed on both sides of the upper end of the base plate 1, and several rotating shafts 12 are equidistantly installed between the two side plates 11 to reduce friction and make the wooden board move more smoothly.

[0030] Furthermore, fixing plates 7 are fixedly installed on both sides of the upper end of the connecting plate 2, and several rotating shafts 71 are equidistantly installed between the two fixing plates 7 to support and transport the sanded wooden board, so as to prevent the wooden board from colliding with the vacuum head 61 located below.

[0031] The working principle of this embodiment:

[0032] Step 1: Connect the air inlet of the external vacuum cleaner to the connecting hose 62 via the connecting flange 63 provided with the device, ensuring that the vacuum hose 6 is sealed and unobstructed. Based on the actual thickness of the wood board to be treated, activate the cylinder 5 at the top of the bracket 3. The telescopic rod of the cylinder 5 will drive the upper mounting plate 4 to rise and fall vertically (the lower mounting plate 4 is fixed) until the gap between the upper and lower sandpaper rollers 41 matches the thickness of the wood board (ensuring that the sandpaper rollers 41 can fit against the surface of the wood board without damaging it or failing to sand it properly). At the same time, the two guide rods 51 at the upper end of the upper mounting plate 4 slide synchronously along the through hole of the bracket 3. The movement direction of the mounting plate 4 is limited to prevent it from tilting and causing uneven contact between the sandpaper roller 41 and the wooden board, thus ensuring the sanding accuracy. The wooden board to be deburred is placed on the rotating shaft 12 on the base plate 1 (the side plates 11 on both sides of the base plate 1 can laterally limit the wooden board to prevent it from shifting). Since the rotating shaft 12 is a rotating structure, the wooden board can slide smoothly along the surface of the rotating shaft with manual pushing or external conveying mechanism assistance, and enter the sanding area between the upper and lower sandpaper rollers 41. The rolling design greatly reduces the frictional resistance between the wooden board and the device, and avoids new scratches on the surface of the wooden board due to sliding friction.

[0033] Step 2: Start the drive motors 42 on the two mounting plates 4. The drive motors 42 drive the corresponding sandpaper rollers 41 to rotate at high speed. When the wood board passes between the upper and lower sandpaper rollers 41, the sandpaper on the surface of the sandpaper rollers 41 will come into close contact with the upper and lower surfaces of the wood board. Through the grinding action of the sandpaper, the burrs, protrusions, rough edges and other impurities on the surface of the wood board are quickly removed. At the same time, the surface of the wood board is initially polished to make the door surface flat and smooth. Since the upper and lower sandpaper rollers 41 work synchronously, the deburring process of both sides of the wood board can be completed in one go.

[0034] Step 3: During the sanding process of the sandpaper roller 41, the external dust collection equipment is started simultaneously. The dust collection pipe 6 and the dust collection head 61 are used to collect dust in real time in the sanding area. The dust collection head 61 on the lower dust collection pipe 6 is perpendicular to the direction of the bracket 3 and the opening is facing upward. It can accurately absorb the wood chips generated by sanding the lower surface of the wood board. The dust collection head 61 on the upper dust collection pipe 6 is tilted downward. It can cover the dust on the upper surface of the wood board and the dust near the sandpaper roller 41. The horn-shaped dust collection head 61 expands the dust collection range and improves the efficiency of impurity adsorption, ensuring that there is no dust accumulation in the sanding area. This does not affect the sanding effect of the sandpaper roller 41 and also protects the health of the operators. After being sanded by the upper and lower sandpaper rollers 41, the wood board continues to be fed from the other side of the sandpaper roller 41 and leaves the device through the subsequent auxiliary conveying structure (or manual guidance). At this time, the burrs on the surface of the wood board have been completely removed and can enter the next process (such as painting, splicing, etc.).

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
