Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and in particular to a wood product processing and polishing mechanism. Background Technology

[0002] In the wood processing industry, polishing, especially the surface treatment of boards, is a key process for improving the appearance and texture of products. Currently, common polishing equipment often uses two conveyor mechanisms arranged in a cross shape: one is used to carry and transport the board to be polished, and the other is used to install and transport polishing sandpaper (or sanding belt). Through the perpendicular and intersecting movement of the two conveyors, the sandpaper and the surface of the board are made to generate relative friction, thereby achieving the purpose of polishing.

[0003] During the polishing process, since the two conveyors only move in a fixed direction in a straight line, the contact and friction path between the sandpaper and the board is relatively fixed and highly repeatable. The friction trajectory of the sandpaper on the board is basically a single, straight line or slightly intersecting lines in the same direction. The polishing path is highly consistent and lacks variation in friction mode, making it difficult to obtain a uniform and delicate texture effect on the surface of the board. Utility Model Content

[0004] In view of the fact that the contact and friction path between existing sandpaper and board is relatively fixed and highly repeatable, making it difficult to obtain a uniform and delicate texture effect on the board surface, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a wood product processing and polishing mechanism, the purpose of which is that the contact trajectory between the board surface and the sandpaper changes non-linearly, breaking the limitations of the traditional fixed path.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a wood product processing and polishing mechanism, including a base plate, a sliding chamber slidably installed on the top of the base plate, a belt conveyor for placing boards installed inside the sliding chamber, a bracket fixed on the top of the base plate, two electric telescopic rods fixed on the top of the bracket, and a polishing component installed between the movable ends of the two electric telescopic rods;

[0007] A guide rail is installed on the top of the base plate and below the translation chamber. A slider is installed on the bottom of the translation chamber, directly opposite each guide rail. A reciprocating translation component for pushing the translation chamber to move back and forth is installed on the top of the base plate and on one side of the translation chamber, and the movable end of the reciprocating translation component is fixed to the side of the translation chamber.

[0008] As an improved technical solution, multiple sets of U-shaped positioning frames are installed at equal intervals on the outer wall of the conveying end of the belt conveyor. Two U-shaped positioning frames in the same set are arranged in a relative state, and a cavity for restricting the plate is formed between the two U-shaped positioning frames in the same set.

[0009] As an improved technical solution, the polishing assembly includes a U-shaped frame fixed to the telescopic end of an electric telescopic rod. Both sides of the U-shaped frame are equipped with drive rollers, and a drive motor for driving the drive rollers to rotate is installed at one end of the outer side of the U-shaped frame. A conveyor belt is installed between the two drive rollers, and polishing sandpaper is adhered to the outer wall of the conveyor belt.

[0010] As an improved technical solution, the reciprocating translation assembly includes multiple rotating shafts rotatably mounted on the top of the base plate. A rotating disk is fixed to the end of the rotating shaft away from the base plate, and a push-pull strip is rotatably installed between the top of the rotating disk and the outer wall of the translation chamber.

[0011] As an improved technical solution, a second mounting shaft is rotatably mounted on the outer edge of the end face of the rotating disk away from the rotating shaft, and a first mounting shaft is rotatably mounted on the side of the translation chamber near the push-pull bar via a bearing, with a push-pull bar rotatably mounted between the first mounting shaft and the second mounting shaft.

[0012] As an improved technical solution, a synchronous pulley is sleeved on the rotating shaft, and a synchronous belt is installed between multiple synchronous pulleys. A set of tensioning pulleys for limiting the synchronous belt is installed on the top of the base plate and between two adjacent rotating shafts.

[0013] As an improved technical solution, the reciprocating translation component also includes a servo motor mounted on the top of the base plate. The drive end of the servo motor is fixedly mounted with a drive gear, and a driven gear meshing with the drive gear is sleeved on the rotating shaft near the drive gear.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a servo motor drives a drive gear to rotate. Under the meshing transmission of the drive gear and the driven gear, the servo motor directly drives an outer rotating shaft to rotate. Under the transmission of the synchronous belt and the synchronous pulley, multiple rotating shafts rotate synchronously. That is, one servo motor can drive multiple rotating shafts to rotate synchronously at the same time, reducing production and usage costs.

[0016] 2. This utility model drives the board to move laterally back and forth through a reciprocating translation component, so that the board produces a compound motion of swaying and moving forward during the polishing process, which greatly improves the uniformity of the polished surface, significantly enhances the polishing effect, and makes the texture more uniform and delicate. In addition, the swaying of the board helps to automatically shake off the wood chips and dust generated during the polishing process, reducing their accumulation in the contact area between the sandpaper and the board. This not only effectively avoids the accumulation of wood chips, but also improves the utilization rate of sandpaper. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0024] Reference Figures 1-3This is the first embodiment of the present invention, which provides a wood product processing and polishing mechanism. This wood product processing and polishing mechanism includes a base plate 1, a sliding chamber 2 slidably installed on the top of the base plate 1, a belt conveyor 3 for placing boards installed inside the sliding chamber 2, a bracket fixed on the top of the base plate 1, and the sliding chamber 2 passing through the interior of the bracket. Two electric telescopic rods 6 are fixed on the top of the bracket, and the telescopic ends of the electric telescopic rods 6 are located inside the bracket. A polishing component 5 is installed between the movable ends of the two electric telescopic rods 6, and the polishing component 5 is located directly above the belt conveyor 3 and is in a cross-shaped offset state from the belt conveyor 3. The extension of the electric telescopic rods 6 drives the polishing component 5 to move longitudinally, and the height of the polishing component 5 is adjusted according to the thickness of the board, so that the polishing sandpaper 52 is tightly and fully attached to the outer wall surface of the board, thereby improving the polishing quality and the flexibility of the polishing mechanism.

[0025] A guide rail is installed on the top of the base plate 1 and below the translation chamber 2. A slider is installed on the bottom of the translation chamber 2 and at the position of each guide rail. The slider slides on the guide rail. A reciprocating translation component 7 for pushing the translation chamber 2 to move back and forth is installed on the top of the base plate 1 and on one side of the translation chamber 2. The movable end of the reciprocating translation component 7 is fixed to the side of the translation chamber 2.

[0026] The reciprocating translation component 7 drives the board to move laterally back and forth, causing the board to generate a complex motion of swaying and moving forward during the polishing process. This makes the relative motion trajectory between any point on the board surface and the sandpaper running above it complex and varied, no longer a straight-line friction in a single direction. This greatly improves the uniformity of the polished surface, significantly enhances the polishing effect, and makes the texture more uniform and delicate. In addition, the swaying of the board helps to automatically shake off the wood chips and dust generated during the polishing process, reducing their accumulation in the contact area between the sandpaper and the board. This not only effectively avoids wood chip accumulation but also improves the utilization rate of the sandpaper.

[0027] Multiple sets of U-shaped positioning frames 4 are installed at equal intervals on the outer wall of the conveyor end of the belt conveyor 3. Two U-shaped positioning frames 4 in the same group are set in a relative state, and a cavity is formed between the two U-shaped positioning frames 4 in the same group to limit the plate. The cavity between the two U-shaped positioning frames 4 in the same group is used to limit the plate to be polished. On the one hand, it can limit the plate in the polishing state and prevent the plate from deviating during the polishing process, thereby improving the polishing effect of the plate.

[0028] The polishing assembly 5 includes a U-shaped frame 51 fixed to the telescopic end of the electric telescopic rod 6. Both sides of the U-shaped frame 51 are equipped with drive rollers 54. One end of the outer side of the U-shaped frame 51 is equipped with a drive motor for rotating the drive rollers 54. The drive end of the drive motor is connected to the shaft end of the drive rollers 54. A conveyor belt 53 is installed between the two drive rollers 54. Polishing sandpaper 52 is adhered to the outer wall of the conveyor belt 53.

[0029] The reciprocating translation component 7 includes multiple rotating shafts 71 rotatably mounted on the top of the base plate 1. A rotating disk 72 is fixed to one end of the rotating shaft 71 away from the base plate 1. A push-pull strip 73 is rotatably mounted between the top of the rotating disk 72 and the outer wall of the translation chamber 2. The rotation of the rotating disk 72 will reciprocate and pull the translation chamber 2 in a horizontal movement state through the push-pull strip 73. That is, the board is in a reciprocating horizontal movement state during the polishing process, which changes the contact path between the polishing sandpaper 52 and the board and helps to improve the polishing effect.

[0030] The rotating disk 72 is rotatably mounted on the outer edge of the end face away from the rotating shaft 71. The translation chamber 2 is rotatably mounted on the side near the push bar 73 via a bearing, and the push bar 73 is rotatably mounted between the mounting shaft 74 and the mounting shaft 75.

[0031] A synchronous pulley 78 is sleeved on the rotating shaft 71, and a synchronous belt 77 is installed between multiple synchronous pulleys 78. A set of tensioning pulleys 76 for limiting the synchronous belt 77 is installed on the top of the base plate 1 and between two adjacent rotating shafts 71. The synchronous belt 77 is located between two tensioning pulleys 76 in the same set.

[0032] The reciprocating translation assembly 7 also includes a servo motor 710 mounted on the top of the base plate 1. The drive end of the servo motor 710 is fixedly mounted with a drive gear 711. A driven gear 79 that meshes with the drive gear 711 is sleeved on a rotating shaft 71 near the drive gear 711. The servo motor 710 directly drives one of the outer rotating shafts 71 to rotate. Under the transmission action of the synchronous belt 77 and the synchronous pulley 78, multiple rotating shafts 71 rotate synchronously. That is, one servo motor 710 can drive multiple rotating shafts 71 to rotate synchronously at the same time, reducing production and usage costs.

[0033] The working principle of this utility model is as follows: The plate is placed on the conveyor belt of the belt conveyor 3 and located between the two U-shaped positioning frames 4 in the same group. The belt conveyor 3 drives the plate to move towards the polishing assembly 5.

[0034] When the board passes under the polishing component 5, the drive motor drives the polishing sandpaper 52 to rotate. Under the high-speed rotation of the polishing sandpaper 52, the outer wall surface of the board is polished.

[0035] While the belt conveyor 3 is conveying the plates, the servo motor 710 drives the drive gear 711 to rotate. Under the meshing transmission of the drive gear 711 and the driven gear 79, the servo motor 710 directly drives an outer rotating shaft 71 to rotate. Under the transmission of the synchronous belt 77 and the synchronous pulley 78, multiple rotating shafts 71 rotate synchronously.

[0036] The rotating disk 72 rotates along with the rotating shaft 71. Under the linkage of the push-pull bar 73, the mounting shaft 1 74 and the mounting shaft 2 75, the rotation of the rotating disk 72 will reciprocate through the push-pull bar 73 to move the translation chamber 2 in a horizontal state. That is, the board is in a reciprocating horizontal state during the grinding process, which changes the contact path between the polishing sandpaper 52 and the board, which is beneficial to improving the grinding effect.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
