Description

Technical Field

[0001] This utility model relates to the field of wood polishing technology, specifically a poplar wood polishing device. Background Technology

[0002] Polishing machines, also known as grinding machines, are commonly used for mechanical grinding, polishing, and waxing. Their working principle is as follows: an electric motor drives a sponge or wool polishing disc mounted on the machine to rotate at high speed. Due to the combined action of the polishing disc and polishing compound, friction is applied to the surface to be polished, thereby removing paint contaminants, oxide layers, and shallow scratches. Polishing and sanding have almost the same effect; for wood, polishing can remove burrs and rough surfaces, making them smoother.

[0003] Currently, most wood polishing devices only have one polishing roller above the conveyor structure, which can only polish the upper surface of the wood. To completely polish a wood board, the polishing surface needs to be adjusted multiple times and the polishing process needs to be repeated, so there is room for improvement in work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a poplar wood polishing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A poplar wood polishing device, comprising: The material conveying structure includes a material conveying frame, wherein a polishing wheel built-in groove is provided in the middle of the material conveying frame, and polishing wheel support frames are fixedly installed on both sides of the upper surface of the material conveying frame; The lower pressure frame is fixedly installed above the opening of the internal groove of the polishing wheel and on the upper side of one end of the material conveyor; The No. 1 grinding structure is rotatably installed between the internal groove of the polishing wheel and the polishing wheel support frame; The No. 2 grinding structure is rotatably mounted on both sides of the material conveyor.

[0006] Furthermore, the bottom of the material conveyor is fixedly installed with a support leg column by a corner bracket, and a limit groove is opened on the upper side of the material conveyor. The middle of the limit grooves on both sides of the polishing wheel is rotatably sleeved with a conveyor belt.

[0007] Furthermore, the lower pressure frame includes: Side brackets are fixedly installed on both sides of the opening in the limiting groove; The limiting slide is located inside the side frame; The limit slider is engaged inside the limit groove; The pressure roller has its end rotatably connected to the limit slider. The force plate is slidably attached to the upper end of the limiting groove; The compression spring is fitted between the limit slider and the force plate; An adjusting screw is screwed onto the upper end of the side frame, and the lower end of the adjusting screw is rotatably connected to the limiting slider.

[0010] Furthermore, the first and second rotating shafts are fitted with bushings on their side surfaces, and a felt polishing wheel is fixedly fitted onto the side surface of the bushing.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The slit poplar planks are placed on the upper surface of the conveyor frame and continuously moved forward under the pressure and limiting of the lower press frame. First, two sets of No. 2 grinding structures grind and polish the two sides of the planks. Then, the lower press frame above the built-in groove of the polishing wheel presses the planks, forcing the bottom surface of the planks into close contact with the No. 1 grinding structure in the built-in groove of the polishing wheel, thus grinding and polishing the bottom of the planks. As the planks continue to move forward, the No. 1 grinding structure installed between the polishing wheel support frames finally grinds and polishes the upper surface of the planks. During the movement of the planks, all four sides can be ground and polished simultaneously, eliminating the need for traditional grinding devices to grind different sides of the planks multiple times and to adjust the turning of the grinding surface, greatly improving work efficiency.

[0012] 2. The No. 1 rotating shaft is installed inside the limiting groove and polishing wheel support frame by snap-fit. The limiting end and the limiting sleeve are interlocked and fixed with bolts to achieve limiting. The No. 1 motor is connected by the interlocking sleeve and the interlocking end.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5In this embodiment of the utility model, a poplar wood polishing device includes a material conveying structure 1, which includes a material conveying frame 101. The material conveying frame 101 has a polishing wheel built-in groove 104 in the middle, and polishing wheel support frames 105 are fixedly installed on both sides of the upper surface of the material conveying frame 101; a lower pressure frame 2, which is fixedly installed above the opening of the polishing wheel built-in groove 104 and on the upper side of one end of the material conveying frame 101; a first grinding structure 3, which is rotatably installed in the polishing wheel built-in groove 104 and between the polishing wheel support frame 105; and a second grinding structure 4, which is rotatably installed on both sides of the material conveying frame 101.

[0017] Specifically, the slit and standardized poplar boards are placed on the upper surface of the feeding frame 101 and continue to move under the pressure and limit of the lower pressure frame 2. First, two sets of No. 2 grinding structures 4 grind and polish the two sides of the boards. Then, the lower pressure frame 2 above the polishing wheel's built-in groove 104 presses down on the boards, forcing the bottom surface of the boards into close contact with the No. 1 grinding structure 3 in the polishing wheel's built-in groove 104, thus grinding and polishing the bottom of the boards. As the boards continue to move, the No. 1 grinding structure 3 installed between the polishing wheel support frames 105 finally grinds and polishes the upper surface of the boards. During the movement of the boards, all four sides can be ground and polished simultaneously, eliminating the need for traditional grinding devices to grind different sides of the boards multiple times and to adjust the grinding surfaces by flipping them over, greatly improving work efficiency.

[0018] Example 1 like Figure 1 As shown, in this embodiment, the bottom of the conveyor frame 101 is fixedly installed with support legs 102 by angle brackets. The upper side of the conveyor frame 101 has a limiting groove 103. The middle of the limiting grooves 103 on both sides of the polishing wheel's internal groove 104 is rotatably sleeved with a conveyor belt 106. The lower pressing frame 2 includes: a side frame 201, which is fixedly installed on both sides of the opening of the limiting groove 103; a limiting slide groove 202, which is opened inside the side frame 201; and a limiting slider 203, which slides and locks. The following components are attached to the inside of the limiting slide groove 202: a pressure roller 204, the roller end of which is rotatably connected to the limiting slider 203; a force plate 205, which is slidably engaged with the upper end of the limiting slide groove 202; a downward pressure spring 206, which is engaged between the limiting slider 203 and the force plate 205; an adjusting screw 207, which is screwed onto the upper end of the side frame 201, and the lower end of the adjusting screw 207 is rotatably connected to the limiting slider 203; and an adjusting knob 208, which is fixedly installed on the upper end of the adjusting screw 207.

[0019] In this embodiment, the pressure spring 206 provides thrust to the limiting slider 203, giving the pressure roller 204 a constant downward pressure tendency. The adjusting knob 208 can be used to rotate the adjusting screw 207 to adjust the actual height of the force plate 205 at the top of the limiting groove 202, thereby adjusting the upper limit position of the pressure spring 206 and adjusting the downward pressure of the pressure roller 204. The pressure roller 204 presses the wooden board into the limiting groove 103, and the conveyor belt 106 continuously moves the wooden board forward. The pressure roller 204 directly presses the wooden board above the polishing wheel's built-in groove 104, avoiding the felt polishing wheel 308 in the polishing wheel's built-in groove 104 from supporting the wooden board and affecting the tightness of the fit, thus affecting the polishing effect.

[0020] Example 2 Based on Example 1, this invention supplements the specific method for replacing the felt polishing wheel 308 after prolonged and excessive wear, which was not mentioned in Example 1.

[0021] like Figure 5 As shown, in this embodiment, the first polishing structure 3 includes: a limiting sleeve 301, which is mounted on one side of the polishing wheel's internal groove 104 and the polishing wheel support frame 105 via bearings; a limiting end 302, which is engaged with the limiting sleeve 301; a first rotating shaft 303, which is fixedly mounted on one side of the limiting end 302; a engaging end 304, which is fixedly mounted on one end of the first rotating shaft 303; a first motor 305, which is fixedly mounted on the other side of the polishing wheel's internal groove 104 and the polishing wheel support frame 105; and a engaging sleeve 306, which is fixedly mounted on the output end of the first motor 305. 06 is interlocked with the snap-fit ​​end 304 that passes through the built-in groove 104 of the polishing wheel and the polishing wheel support frame 105; the second grinding structure 4 includes: a mounting plate 401, which is fixedly installed on both sides of the material conveyor 101; a second motor 402, which is fixedly installed on the bottom side of the mounting plate 401; a second rotating shaft 403, which is fixedly installed on the output end of the second motor 402; a fixing plate 404, which is fixedly installed on the upper end of the second rotating shaft 403 by bolts; a bushing 307 is sleeved on the side surface of the first rotating shaft 303 and the second rotating shaft 403, and a felt polishing wheel 308 is fixedly sleeved on the side surface of the bushing 307.

[0022] In practice, the first rotating shaft 303 is rotatably installed inside the limiting groove 103 and the polishing wheel support frame 105 by snap-fitting. The limiting end 302 and the limiting sleeve 301 are interlocked and fixed with bolts to achieve limiting. The first motor 305 is connected to the interlocking sleeve 306 and the interlocking end 304. The first rotating shaft 303 can be directly pulled out to facilitate the replacement of the felt polishing wheel 308 installed in the polishing wheel groove 104 and the polishing wheel support frame 105. At the same time, the felt polishing wheel 308 sleeved at the second rotating shaft 403 is fixed by the fixing plate 404 and bolts, which also facilitates its replacement.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
