Description

Technical Field

[0001] This utility model relates to a cylinder pressing and feeding device for a sander, belonging to the field of feeding. Background Technology

[0002] Sanding machines, widely used in the wood processing industry, primarily function to polish the surface of boards, improving their flatness and smoothness. During operation, the feeding device plays a crucial role, ensuring the boards are stably and accurately fed into the sanding area to guarantee even sanding.

[0003] Most existing sanding machine feeding devices use spring-loaded feeding. While this method can meet basic feeding needs to a certain extent, it also has several problems. First, springs are prone to breakage under long-term stress from tension and compression, which can lead to malfunctions in the feeding device and potentially cause safety accidents. Second, with increased usage time and frequency, the elasticity of the springs gradually decreases. This shortens the stroke of the pressure roller, resulting in insufficient pressure and difficulty in effectively pressing the sheet metal onto the feeding roller, thus affecting the normal operation of the sanding machine.

[0004] Furthermore, decreased spring elasticity makes it difficult to precisely control the clamping force, causing the sheet material to slip or deviate during feeding, further affecting sanding quality and production efficiency. In actual production, due to insufficient clamping, the sheet material may sometimes bounce back, causing accidents that result in injury or property damage, leading to significant economic losses and safety hazards for the company.

[0005] In summary, existing sanding machine feeding devices have significant shortcomings in terms of stability and safety. There is an urgent need for an improved feeding device to solve the problems existing in the current technology, improve the working performance and production efficiency of the sanding machine, and at the same time ensure the personal safety of the operators.

Those skilled in the art should understand that modifications or substitutions can be made to the details and form of the technical solution of the present invention without departing from the spirit and scope of the present invention, but all such modifications and substitutions fall within the protection scope of the present invention.

[0021] See Figure 1 and Figure 2 This utility model relates to a cylinder-driven pressing and feeding device for a sander, comprising: a pressing cylinder 1, mounted on the upper frame and arranged vertically, for providing a constant air pressure driving pressing force; a limiting component for limiting the lifting height of the upper pressing roller 8; a guiding mechanism for guiding the upper pressing roller 8 when it moves up and down; the upper pressing roller 8, rotatably mounted on the upper frame and guided by the guiding mechanism, the upper pressing roller 8 floating up and down with the thickness of the sheet material; a lower feeding roller 9 for supporting the sheet material, rotatably mounted on the lower frame, and forming a space for sheet material conveying between the roller and the upper pressing roller 8; the air pressure output of the pressing cylinder 1 is dynamically adjusted by an external pressure regulating valve to achieve flexible pressing of sheets of different thicknesses.

[0022] Based on the above structural design, this utility model achieves the following advantages:

[0023] Constant air pressure drive: The pressing cylinder 1 provides constant air pressure to drive the clamping force, ensuring stable and reliable pressing force and avoiding the problem of insufficient pressing force caused by the deterioration of spring elasticity in the traditional spring pressing method.

[0024] Dynamic adjustment: The air pressure output can be dynamically adjusted by an external pressure regulating valve, which can precisely control the clamping force according to the thickness of the board, achieve flexible clamping, and ensure that the board remains in a stable state during the sanding process.

[0025] Limiting component: The limiting component includes adjusting block 7 and limiting bolt 2. By adjusting the height of bolt 2 on limiting block 3, the lifting height of upper pressure roller 8 can be precisely controlled to ensure that the distance between pressure roller and plate is appropriate, thereby improving sanding quality and efficiency.

[0026] Guide mechanism: Provides stable guidance for the up and down movement of the upper pressure roller 8, ensuring that the pressure roller runs smoothly during the lifting process and avoiding uneven pressing caused by shaking or deviation.

[0027] Flexible clamping: The air pressure output of the clamping cylinder 1 can be dynamically adjusted by an external pressure regulating valve, which can adapt to boards of different thicknesses and ensure that the appropriate clamping force is applied to the board during the sanding process, avoiding damage to the board or uneven sanding caused by excessive or insufficient clamping force.

[0028] Up and down floating: The upper pressure roller 8 floats up and down with the change of the plate thickness, which can automatically adapt to the change of plate thickness and ensure that the pressure roller always maintains good contact with the plate, thereby improving the sanding quality and efficiency.

[0029] Stable operation: By using a cylinder pressing method, the equipment failure caused by spring breakage or loss of elasticity in the traditional spring pressing method is avoided, which improves the stability and reliability of the equipment and extends its service life.

[0030] This utility model's air cylinder pressing and feeding device for sanding machines solves the problems existing in the traditional spring pressing method by adopting an air cylinder pressing method. It has the advantages of stable and reliable pressing force, precise lifting height control, adaptability to different thickness plates, improved equipment service life, and improved production efficiency and safety. It has broad application prospects and market potential.

[0031] The guiding mechanism includes a side support plate 6 mounted on the frame, and the limiting component is mounted on the side support plate 6, which is vertically oriented. The vertical orientation of the side support plate 6 provides stable support and guidance for the limiting component, ensuring that the limiting component remains vertical during vertical movement and avoiding inaccurate guidance due to tilting or offset.

[0032] The limiting component is installed on the side support plate 6, and the adjusting block 7 can move smoothly up and down within the range limited by the limiting component, which reduces friction and wear and improves the service life and reliability of the guide mechanism.

[0033] The limiting assembly includes an adjusting block 7 and a limiting bolt 2. The adjusting block 7 is arranged horizontally and mounted on a rotating bearing 4. The limiting bolt 2 is vertically mounted on the upper part of one side of the adjusting block 7, and a guide slider 5 is vertically mounted on the lower part of the other side of the adjusting block 7. The two ends of the upper pressure roller 8 are mounted in the guide slider 5 through the rotating bearing 4. The rotating bearing 4 slides up and down in the groove of the guide slider 5. The adjusting block 7 is driven by the pressure cylinder 1.

[0034] It also includes a limiting block 3, on which a limiting bolt 2 is installed. By adjusting the height of the bolt 2 on the limiting block 3, the limiting distance can be adjusted. Adjusting the height of the limiting bolt 2 on the limiting block 3 allows for precise control of the lifting height of the upper pressure roller 8, ensuring a suitable distance between the pressure roller and the material, thus improving sanding quality and efficiency. The guiding mechanism provides precise guidance for the up-and-down movement of the limiting assembly, ensuring stability during adjustment and preventing inaccurate lifting height due to shaking or offset.

[0035] The working principle of this utility model is as follows:

[0036] 1. Start the pressure cylinder:

[0037] The pressing cylinder 1 is mounted on the upper frame and is set vertically. When the device is started, the pressing cylinder 1 provides a constant pressing force through air pressure output.

[0038] 2. Adjusting block for the pressure cylinder drive:

[0039] The piston rod of the pressing cylinder 1 is connected to the adjusting block 7, which drives the adjusting block 7 to move downward along the side support plate 6.

[0040] 3. The adjusting block drives the rotating bearing 4 and the upper pressure roller 8:

[0041] The adjusting block 7 is set horizontally and slidably mounted on the side support plate 6. When the adjusting block 7 moves downward, it drives the rotating bearing 4 and the upper pressure roller 8 connected to it to move downward together within the guide slider 5.

[0042] 4. Limiting components restrict the lifting height:

[0043] The limiting bolt 2 is installed on the limiting block 3. By adjusting the height of the limiting bolt 2 on the limiting block 3, the lifting height of the upper pressure roller 8 can be precisely controlled. The limiting assembly ensures that the distance between the upper pressure roller 8 and the sheet material is appropriate.

[0044] 5. The guiding mechanism provides stable guidance:

[0045] The guide slider 5 has a groove that provides stable guidance for the up-and-down movement of the upper pressure roller 8. The guide slider 5 is mounted on the side support plate 6 to ensure that the upper pressure roller 8 runs smoothly during the lifting and lowering process.

[0046] 6. The upper pressure roller moves up and down according to the thickness of the sheet material:

[0047] The upper pressure roller 8 is mounted on the guide slider 5 at both ends via rotating bearings 4, allowing it to float up and down as the thickness of the sheet changes. The rotating bearings 4 slide up and down within the grooves of the guide slider 5, ensuring that the upper pressure roller 8 always maintains good contact with the sheet.

[0048] 7. Lower feed roller supports the plate:

[0049] The lower feed roller 9 is mounted on the lower frame to support the sheet metal and forms a space for sheet metal conveying between it and the upper pressure roller 8. When the lower feed roller 9 rotates, it drives the sheet metal forward.

[0050] 8. Dynamically adjust clamping force:

[0051] The air pressure output of the pressure cylinder 1 is dynamically adjusted through an external pressure regulating valve, which can precisely control the clamping force according to the thickness of the sheet material, achieving flexible clamping. This ensures that the appropriate clamping force is applied to the sheet material during the sanding process, avoiding damage to the sheet material or uneven sanding caused by excessive or insufficient clamping force.

[0052] Through the above steps, the pneumatic cylinder pressing and feeding device for sanding machines of this utility model achieves advantages such as stable and reliable clamping force, precise lifting height control, adaptability to different thicknesses of plates, improved equipment service life, and enhanced production efficiency and safety. The pneumatic cylinder pressing method avoids the problems existing in the traditional spring pressing method, ensuring the stability and reliability of the equipment during operation, and has broad application prospects and market potential.
