Description

Technical Field

[0001] This utility model specifically relates to a surface leveling device for wood product processing, belonging to the field of wood product processing technology. Background Technology

[0002] Wood products typically require surface leveling during processing. The purpose of leveling is to create a smooth, even surface, improving the product's appearance and lifespan. This is usually achieved by using a planer or sandpaper to remove burrs and protruding particles, or by using sandpaper, grinding wheels, or belt sanders to polish the surface, removing imperfections and unevenness for a smoother finish. However, some existing wood leveling devices can only set the sanding roller to a certain height and sand the wood product at the same height. This method is unsuitable for addressing specific surface imperfections in practical applications. The existing surface leveling device, which is designed to level uneven surfaces, has low practicality. To address this, Chinese Patent Publication No. CN221604028U discloses a surface leveling device for wood product processing. This device uses a second slider to drive the sanding roller to slide up and down, thereby improving the leveling effect on wood products. However, existing leveling devices are prone to edge warping and tilting of the wood product when the sanding roller contacts the end of the wood product. Furthermore, during the feeding process of the wood product onto the sanding roller, it is easily contaminated by the table surface, resulting in an uneven bottom surface. Additionally, friction and vibration between the bottom surface of the wood product and the table surface can easily lead to localized over-sanding and damage to the surface flatness. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes a surface leveling device for wood product processing. This device can limit the external dimensions and press the top of the wood product profile before performing surface leveling, ensuring the consistency of the entire profile surface during the leveling process.

[0004] The present invention relates to a surface leveling device for wood product processing, comprising a base, wherein a linear sliding component is fixed to the top of the base; and a surrounding plate is fixed to the outside of the base. A positioning push plate, comprising a sliding plate body, wherein a locking plate component is provided on the sliding plate body; the bottom surface of the sliding plate body is fixed to the sliding end of a linear sliding component; the sliding plate body is movably disposed inside the enclosure panel; A leveling unit includes a hollow cavity seat with a hollow top surface. Supports are fixed to the outer sides of both ends of the cavity seat. A sliding column is slidably mounted on the support, and the sliding column is fitted and fixed to the surrounding plate. A leveling and grinding component is fixed to the bottom of the inner side of the cavity seat. The pressure plate unit includes support arms fixed to the middle of both sides of the cavity seat. A row of pressure rollers is fixed to the bottom surface of the support arms at intervals through roller seats. The bottom surface of the pressure rollers is flush with the bottom grinding surface of the leveling and grinding part. A strain pressure unit is provided on the support arm on the input side. The bottom surface of the strain pressure unit protrudes from the bottom surface of the pressure rollers. A guide post is fixed to the top of the support arm. A spanning plate is fixed across the outer side of the top of the enclosure plate. The guide post moves through the spanning plate. A lifting hydraulic cylinder is fixed to the middle of the top surface of the spanning plate. The piston rod of the lifting hydraulic cylinder moves out of the spanning plate and is fixed to the middle of the top surface of the cavity seat.

[0005] When leveling the surface of the wood product, the wood profile is first placed on the sliding plate. Then, the pressure plate unit actuates, and the piston rod of the lifting hydraulic cylinder drives the chamber seat downward. During the linear descent, the guide columns and sliding columns provide linear guidance, ensuring that the leveling unit and the pressure plate unit slide linearly. When the pressure roller and the strain pressure unit contact the top surface of the wood profile, the lifting hydraulic cylinder drives the leveling unit and the pressure plate unit to continue descending until the strain pressure unit reaches the set pressure value. At this point, the lifting hydraulic cylinder locks in place, and the pressure roller on the support arm presses the wood profile tightly. Next, the outer edge of the wood profile is locked by the locking plate, and the top surface of the wood profile is flush with the top surface of the locking plate. Then, the linear sliding component drives the sliding plate to slide linearly. Since the bottom surfaces of the pressure roller and the leveling and grinding component are flush, the wood profile is fed smoothly. The leveling and grinding component can then grind the top surface of the wood board to a smooth finish. After the grinding is completed, the lifting hydraulic cylinder is reset, and the ground wood board is removed from the leveling and grinding component. Then, the locking plate is reset, and the ground wood board can be removed from the sliding plate.

[0006] Furthermore, the linear sliding component includes a linear slide rail fixed on the base, a dovetail slider slidably disposed on the linear slide rail, and the dovetail slider fixed to the bottom surface of the slide plate body; an inlet / outlet pusher is fixed to the end of the slide plate body; after the top surface and side of the wooden profile are limited, the slide plate body is then driven to slide linearly by the inlet / outlet pusher, thereby realizing that the wooden profile on the slide plate body is continuously sanded and leveled by the leveling and sanding component.

[0007] Furthermore, the linear sliding component includes an electric linear slide fixed on the base, and the slide body is fixed to the slider of the electric linear slide. After the top surface and side of the wood profile are limited, the slide body is then driven by the electric linear slide to slide in a straight line, thereby realizing that the wood profile on the slide body is continuously polished and leveled by the leveling and sanding component.

[0008] Furthermore, the leveling and sanding component is a sanding roller or sanding belt driven by a motor; when the top surface of the wood product profile is leveled, it is sanded and leveled by the sanding roller or sanding belt, and the top surface of the wood product profile is on the same plane after sanding and leveling.

[0009] Furthermore, the locking plate includes multiple grooves spaced apart on both sides of the sliding plate body, and the two ends of the sliding plate body are integrally formed with raised edges; a locking block is slidably disposed inside the groove; a locking hydraulic cylinder is fixed to the bottom surface of the sliding plate body, and the locking hydraulic cylinder is fixed to the locking block; the locking block is flush with the top surface of the raised edge; in use, the wooden profile is first placed on the top surface of the sliding plate body and pressed by the pressure plate unit. Then, the locking block is driven by the locking hydraulic cylinder to slide linearly along the groove, so that the locking block can clamp the edge of the wooden profile, thereby clamping both sides of the wooden profile. As the sliding plate body slides, the rear end of the wooden profile is restricted by the raised edge, thereby limiting the sides and rear end of the wooden profile and enabling the wooden profile to be stably fed to the leveling and sanding part.

[0010] Furthermore, a dust removal connector is fixed to the side of the cavity seat; the dust removal connector is connected to a dust removal fan; the dust removal fan provides suction to the dust removal connector, thereby forming suction inside the cavity seat, sucking the grinding dust to the dust removal fan, and then sending it to the dust collection bin through the dust removal fan.

[0011] Furthermore, the strain pressure unit includes a wheel seat, on which a pressure roller is rolled. A support column is fixed at a distance from the top of the pressure roller. The support column moves through the support arm and is screwed with a limit nut. A pressure strain gauge is fixed between the support column and the top surface of the wheel seat. A spring body is provided between the support column and the wheel seat and the support arm. The spring body causes the pressure roller to protrude from the bottom surface of the pressure roller. When the pressure roller contacts the top surface of the wood product profile, the spring body is compressed until the top surface of the pressure strain gauge presses against the support arm. When the pressure strain gauge reaches the set pressure value, the lifting hydraulic cylinder maintains the current position.

[0012] Compared with the prior art, the surface leveling device for wood product processing of this utility model can limit the outer edge of the wood product profile through the locking plate, and the locking plate does not protrude from the top surface of the wood product profile. At the same time, the top surface of the wood product profile is pressed by the rolling pressure roller, realizing the complete limitation of the wood product profile and preventing edge warping or tilting during the leveling process. Under the rolling and pressing state, the wood product profile is fed linearly to the leveling and grinding part through the sliding plate, which can ensure the consistency of the entire profile surface during the leveling process.

[0020] Example 1: like Figures 1 to 6 The surface leveling device for wood product processing shown includes a base 1, on the top of which a linear sliding component is fixed; and a surrounding plate 2 is fixed to the outside of the base 1. The positioning push plate includes a sliding plate body 3, on which a locking plate component is provided; the bottom surface of the sliding plate body 3 is fixed to the sliding end of the linear sliding component; the sliding plate body is movably disposed inside the enclosure 2; The leveling unit includes a hollow cavity seat 4 with a top surface. Supports 5 are fixed to the outer sides of both ends of the cavity seat 4. A sliding column 6 is slidably mounted on the support 5. The sliding column 6 is fitted and fixed to the surrounding plate 2. A leveling and grinding component 7 is fixed to the bottom inner side of the cavity seat 4. The pressure plate unit includes support arms 8 fixed to the middle of both sides of the cavity seat 4. A row of pressure rollers 10 is fixed at intervals on the bottom surface of the support arms 8 through roller seats 9. The bottom surface of the pressure rollers 10 is flush with the bottom grinding surface of the leveling and grinding part 7. A strain pressure unit 11 is provided on the support arm 8 on the input side. The bottom surface of the strain pressure unit 11 protrudes from the bottom surface of the pressure rollers 10. A guide post 12 is fixed on the top of the support arm 8. A spanning plate 13 is fixed across the outer side of the top of the enclosure plate 2. The guide post 12 moves through the spanning plate 13. A lifting hydraulic cylinder 14 is fixed in the middle of the top surface of the spanning plate 13. The piston rod of the lifting hydraulic cylinder 14 moves out of the spanning plate 13 and is fixed to the middle of the top surface of the cavity seat 4.

[0021] When leveling the surface of the wood product, the wood product profile is first placed on the sliding plate 3. Then, the pressure plate unit is activated, and the piston rod of the lifting hydraulic cylinder 14 drives the cavity seat 4 downward. During the straight downward movement, the guide column 12 and the sliding column 6 provide linear guidance, ensuring that the leveling unit and the pressure plate unit slide linearly. When the pressure roller 10 and the strain pressure unit 11 contact the top surface of the wood product profile, the lifting hydraulic cylinder 14 drives the leveling unit and the pressure plate unit to continue downward until the strain pressure unit 11 reaches the set pressure value. At this time, the lifting hydraulic cylinder 14 locks in place, and the pressure roller 10 on the support arm 8 presses against the wood product. The profile is tightly pressed together; then, the outer side of the wood profile is locked by the locking plate, and the top surface of the wood profile is flush with the top surface of the locking plate; then, the linear sliding component drives the sliding plate 3 to slide linearly, and since the bottom surfaces of the pressure roller 10 and the leveling and grinding component 7 are flush, the top surface of the wood board can be ground flat by the leveling and grinding component 7 while the wood profile is being fed smoothly; after the grinding is completed, the lifting hydraulic cylinder 14 is reset, and the ground wood board is removed from the leveling and grinding component 7. Then, the locking plate is reset, and the ground wood board can be removed from the sliding plate 3.

[0022] The linear sliding component includes a linear slide rail 15 fixed on the base 1, and a dovetail slider 16 slidably disposed on the linear slide rail 15. The dovetail slider 16 is fixed to the bottom surface of the slide plate body 3. An inlet / outlet pusher 17 is fixed to the end of the slide plate body 3. After the top surface and side of the wood product profile are limited, the slide plate body 3 is driven to slide linearly by the inlet / outlet pusher 17, thereby realizing that the wood product profile on the slide plate body 3 is continuously polished and leveled by the leveling and sanding component 7.

[0023] The linear sliding component includes an electric linear slide 19 fixed on the base 1, and the slide body 3 is fixed to the slider of the electric linear slide 19. After the top surface and side of the wood product profile are limited, the slide body 3 is driven to slide in a straight line by the electric linear slide 19, so that the wood product profile on the slide body 3 is continuously polished and leveled by the leveling and sanding component 7.

[0024] The leveling and sanding component 7 is a sanding roller or sanding belt driven by a motor; when the top surface of the wood product profile is leveled, it is sanded and leveled by the sanding roller or sanding belt, and the top surface of the wood product profile is on the same plane after sanding and leveling.

[0025] The locking plate includes multiple grooves 20 spaced apart on both sides of the sliding plate body 3. The sliding plate body 3 has protruding edges 21 integrally formed at both ends. Locking blocks 22 are slidably arranged inside the grooves 20. Pressure strain gauges are fixed on the inner surface of the locking blocks 22 to detect whether the clamping is in place. A locking hydraulic cylinder 23 is fixed on the bottom surface of the sliding plate body 3. The locking hydraulic cylinder 23 is fixed to the locking blocks 22. The top surface of the locking blocks 22 is flush with the top surface of the protruding edges 21. In use, the wooden profile is first placed on the top surface of the sliding plate body 3 and pressed by the pressure plate unit. Then, the locking hydraulic cylinder 23 drives the locking blocks 22 to slide linearly along the grooves 20, so that the locking blocks 22 can clamp the edges of the wooden profile, thereby clamping both sides of the wooden profile. As the sliding plate body 3 slides, the rear end of the wooden profile is restricted by the protruding edges 21, thereby limiting the sides and rear end of the wooden profile and enabling the wooden profile to be stably fed to the leveling and sanding parts 7.

[0026] A dust removal connector is fixed to the side of the cavity seat 4; the dust removal connector is connected to the dust removal fan; the dust removal fan provides suction to the dust removal connector, thereby forming suction inside the cavity seat 4, sucking the grinding dust to the dust removal fan, and then sending it to the dust collection bin through the dust removal fan.

[0027] The strain pressure unit 11 includes a wheel seat 24, on which a pressure roller 25 is rolled. A support column 26 is fixed at a distance from the top of the pressure roller 25. The support column 26 moves through the support arm 8 and is screwed with a limit nut. A pressure strain gauge 18 is fixed between the top surface of the wheel seat 24 and the support column 26. A spring body is provided between the support column 26 and the support arm 8. The spring body causes the pressure roller 25 to protrude from the bottom surface of the pressure roller 10. When the pressure roller 25 contacts the top surface of the wood product profile, the spring body is compressed until the top surface of the pressure strain gauge 18 presses against the support arm 8. When the pressure strain gauge 18 reaches the set pressure value, the lifting hydraulic cylinder 14 maintains the current position.
