Description

Technical Field

[0001] The utility model relates to the technical field of sanding machines, and more specifically to a wood processing sanding machine. Background Art

[0002] Sanding machine, also known as belt sander and polishing machine, is a mechanical equipment used to complete sanding work. It involves a wide range of industries and a wide variety of categories. Among them, in the process of wood processing, it is usually necessary to use a sanding machine to sand the uneven outer wall of the wood to make the outer wall of the wood smoother and flatter, and the thickness is uniform to meet the needs of subsequent processing.

[0003] Chinese patent authorization announcement number: CN218697175U provides a sanding machine for wood processing. This solution can adjust the height of the threaded rod and the back plate at one end of the threaded rod through the designed lifting structure, so that when the back plate is used to clamp the wood, the height of the back plate will never exceed the thickness of the wood itself, avoiding damage to the back plate by the grinding roller during the sanding process, which is conducive to the normal progress of wood processing.

[0004] However, when sanding wood, both sides usually need to be sanded, and this solution can only sand one side of the wood at a time. When sanding the other side, the wood needs to be removed, turned over and re-fixed to meet the requirement that the height of the abutment plate does not exceed the thickness of the wood itself. This increases the number of manual operation steps, brings inconvenience to use, and reduces the efficiency of wood processing. Therefore, a wood processing sanding machine is proposed to address the above problems. Utility Model Content

A pair of symmetrical movable blocks 405 are connected, one end of the movable blocks 405 is fixedly connected to a connecting rod 406 and an electric push rod 408 respectively, one end of the connecting rod 406 is fixedly connected to a clamping plate 407, and the output end of the electric push rod 408 is fixedly connected to a positioning plate 409. The positioning component 4 also includes a second servo motor 403, the second servo motor 403 is installed on the outer end of the mounting plate 402, and the output end of the second servo motor 403 is fixedly connected to a bidirectional lead screw 404, and the end of the bidirectional lead screw 404 away from the second servo motor 403 is rotatably connected to the mounting plate 402, and a pair of movable blocks 405 are both installed with screw sleeves matching the bidirectional lead screw 404.

[0031] Sanding machine, also known as belt sander and polishing machine, is a mechanical equipment used to complete sanding work. It involves a wide range of industries and a wide variety of categories. Among them, in the process of wood processing, it is usually necessary to use a sanding machine to sand the uneven outer wall of the wood to make the outer wall of the wood smoother and flatter, and the thickness is uniform to meet the needs of subsequent processing.

[0032] In this solution, the electric push rod 408 is in an extended state in the initial state, and one end of a pair of positioning plates 409 that is close to each other passes over the clamping plate 407 and comes between the pair of clamping plates 407. At this time, the worker can place the wood on the inner side of the pair of positioning plates 409, so that the edge positions on both sides of the wood overlap the inner end of the positioning plate 409, and then the worker can start the second servo motor 403 to drive the bidirectional screw rod 404 to rotate. When the bidirectional screw rod 404 rotates, it will drive the pair of movable blocks 405 to move through a pair of screw sleeves. The pair of movable blocks 405 slide on the inner end of the mounting plate 402 and move synchronously in the direction of approaching each other, thereby driving the pair of clamping plates 407 to clamp the two ends of the wood. At this time, the bottom ends of both sides of the wood are still in contact with the inner end of the positioning plate 409.

[0033] See also Figure 2-3 The cross-section of the positioning plate 409 is U-shaped, and the positioning plate 409 is arranged on the outside of the clamping plate 407. Gaps are arranged between the upper and lower ends of the clamping plate 407 and the inner wall of the positioning plate 409. A through hole 410 is opened on the positioning plate 409, and the connecting rod 406 passes through the through hole 410.

[0034] After completing the clamping of the wood, the worker starts the first servo motor 401 to drive the mounting plate 402 to rotate 180° to turn the wood over. In this solution, the bottom end of the outer surface of the sanding roller is at the same horizontal position as the top end of the inner wall of the positioning plate 409. Since there are gaps between the upper and lower ends of the clamping plate 407 and the inner wall of the positioning plate 409, the top end of the clamping plate 407 is lower than the upper surface of the wood at this time. Then the worker synchronously starts a pair of electric push rods 408 to retract, so that the positioning plate 409 is separated from the wood and comes to one side of the clamping plate 407. The moved positioning plate 409 will come to both sides of the sanding machine base 3, and will not be on the moving route of the sanding machine base 3. At this time, the worker starts the electric slide rail 2 to drive the sanding machine base 3 to move toward the inner end of the sanding machine body 1, so that the sanding roller can pass through the upper surface of the wood and polish its upper surface, and the sanding roller will not hit the clamping plate 407 or the positioning plate 409, thereby avoiding the sanding roller from damaging equipment other than the wood.

[0035] When the worker needs to sand the other side of the wood, he can first control the sanding machine base 3 to leave the upper side of the wood, and then start the pair of electric push rods 408 again to push the pair of positioning plates 409 in the direction of approaching each other, so that the positioning plates 409 come to the lower ends of both sides of the wood, and then the worker controls the second servo motor 403 to rotate in the opposite direction for a short distance, so that the pair of clamping plates 407 are slightly away from each other. At this time, the wood is separated from the clamping plates 407 and falls downward, and its two ends fall onto the inner wall of the positioning plate 409. Then the worker controls the pair of clamping plates 407 to approach each other again and clamp the wood again, and then controls the first servo motor 401 to rotate 180° again, so that the lower surface of the wood The wood is flipped to the upper side. At this time, the upward surface of the wood is still in contact with the top of the inner wall of the positioning plate 409 after rotating 180°. Then the worker controls the pair of positioning plates 409 to separate from the wood again, and controls the sanding machine base 3 to drive the sanding roller to pass through the wood surface, so as to achieve sanding of the other side of the wood. During the sanding process, the clamping plate 407 or the positioning plate 409 will not be bumped. The worker can pre-set the rotation sequence and rotation angle of the first servo motor 401 and the second servo motor 403 in the above process to proceed in sequence, so that the sanding process on both sides of the wood can be fully automated without the need for manual operation when turning the wood over.

[0036] Working principle:

[0037] The electric push rod 408 is in an extended state in the initial state. One end of a pair of positioning plates 409 that is close to each other passes over the clamping plate 407 and comes between the pair of clamping plates 407. At this time, the worker places the wood on the inner side of the pair of positioning plates 409 so that the edges of the wood on both sides overlap the inner end of the positioning plates 409. Then the worker starts the second servo motor 403 to drive the bidirectional screw rod 404 to rotate. When the bidirectional screw rod 404 rotates, it drives the pair of movable blocks 405 to move through a pair of screw sleeves. The pair of movable blocks 405 slide on the inner end of the mounting plate 402 and move synchronously in the direction of approaching each other. Then, a pair of clamping plates 407 are driven to clamp the two ends of the wood. After completing the clamping of the wood, the worker starts the first servo motor 401 to drive the mounting plate 402 to rotate 180 degrees to turn the wood over. The bottom end of the outer surface of the sanding roller and the top end of the inner wall of the positioning plate 409 are at the same horizontal position, and the top end of the clamping plate 407 is lower than the upper surface of the wood. Then the worker synchronously starts a pair of electric push rods 408 to retract, so that the positioning plate 409 is separated from the wood and comes to one side of the clamping plate 407. The moved positioning plate 409 will come to both sides of the sanding machine base 3, and will not be at the bottom of the sanding machine. The worker then starts the electric slide rail 2 to drive the sanding machine base 3 to move toward the inner end of the sanding machine body 1, so that the sanding roller passes over the upper surface of the wood and polishes its upper surface. The sanding roller will not hit the clamping plate 407 or the positioning plate 409. Then the worker controls the sanding machine base 3 to leave the upper side of the wood, and starts a pair of electric push rods 408 again to push a pair of positioning plates 409 in a direction close to each other, so that the positioning plates 409 come to the lower ends of both sides of the wood. Then the worker controls the second servo motor 403 to rotate in the opposite direction for a short distance, so that the pair of clamping plates 407 are slightly away from each other. The wood then separates from the clamping plate 407 and falls downward, with both ends falling onto the inner wall of the positioning plate 409. The worker then controls the pair of clamping plates 407 to move closer to each other and clamp the wood again. The worker then controls the first servo motor 401 to rotate 180° again to flip the lower surface of the wood to the upper side. At this time, the upward surface of the wood is still in contact with the top of the inner wall of the positioning plate 409 after rotating 180°. The worker then controls the pair of positioning plates 409 to separate from the wood again, and controls the sanding machine base 3 to drive the sanding roller to pass through the surface of the wood, so as to achieve sanding of the other side of the wood.
