Description

Technical Field

[0001] The present invention relates to the technical field of wall panel polishing, and specifically to a polishing mechanism for wall panel processing that is convenient for adjustment. Background Art

[0002] With the rapid development of the current social and economic construction, the demand for solid wood wall panels has been increasing year by year. Solid wood wall panels are made of log and retain the original form of the wood to the greatest extent during the processing, and have good moisture absorption performance, which leads to instability. In addition, the width of general solid wood wall panels on the market is below 200 mm, but when the width of the solid wood wall panel is too large, it is impossible to ensure flatness and small deformations are likely to occur.

[0003] And recessed wire grooves are often provided on the wall panel. Conventional polishing machines mostly use grinding wheels or wool wheels for grinding. However, for some T-shaped grooves, in the position close to the inside of the polishing machine, it is in the grinding dead zone, making it difficult to achieve effective polishing in the above areas. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a polishing mechanism for wall panel processing that is convenient for adjustment, including a grip. A first fixing plate is fixedly connected to the side wall of the grip. A fixing block is fixedly connected to the side wall of the first fixing plate. A driving motor is fixedly connected to the end of the first fixing plate away from the fixing block. The output end of the driving motor is fixedly connected to a driving cylinder, and a grinding belt is sleeved on the outer wall of the driving cylinder; A driving mechanism is fixedly connected to the side wall of the first fixing plate and is used to ensure that the grinding belt is always in a taut state; A linkage mechanism is fixedly connected to the bottom of the fixing block. Before use, the linkage mechanism is first placed inside the groove of the wall panel, and then the worker presses it forcefully, forcing the linkage mechanism to deform; An outward expansion mechanism is fixedly connected to the inner wall of the linkage mechanism and is used to generate deformation inside the groove of the wall panel and fill the grinding belt into the groove of the wall panel; Among them, before use, the staff places the device inside the groove of the wall panel through the grip, and then presses the grip, causing the linkage mechanism to deform and filling the grinding belt into the inner groove of the wall panel. Then, the driving motor drives the grinding belt to rotate inside the groove of the wall panel through the driving cylinder.

[0005] Preferably, the driving mechanism includes: A contraction component, which is fixedly connected to the side wall of the first fixing plate through an extrusion component; The extrusion component includes four telescopic rods fixedly connected to the side wall of the first fixing plate, and the other ends of the four telescopic rods are rotatably connected to a rotating column; A moving component, which is fixedly connected to the side wall of the first fixing plate through a sliding component; The sliding member includes a first fixing rod fixedly connected to one side wall of the fixing plate. A rotating rod is rotatably connected to the side wall of the first fixing rod, and a roller is rotatably connected to the end of the rotating rod away from the first fixing rod. Among them, the four telescopic rods are grouped in pairs, and the two in each group are in a mutually opposing state, ensuring that the two rotating columns are in a rotating state with the outer wall of the abrasive belt.

[0006] Preferably, the linkage mechanism includes: An outward expansion component, which is fixedly connected to the bottom of the fixed block by pressure addition. The pressure member includes a support frame fixedly connected to the bottom of the fixed block. Two rotating columns are rotatably connected to the inner wall of the bottom of the support frame. An outward pushing plate is fixedly connected to the outer walls of the two rotating columns. A limiting plate is fixedly connected to the inner wall of the bottom of the support frame. A control component, which is fixedly connected to the inner wall of the support frame through a linkage member. The linkage member includes a second fixing rod fixedly connected to the inner wall of the support frame. A support block is fixedly connected to the outer wall of the outward pushing plate. A pushing rod is slidably connected to the inner wall of the through hole of the support block. One end of the pushing rod is rotatably connected to the side wall of the second fixing rod. Among them, when the grip drives the support frame to be pressed downward, at this time the two outward pushing plates will be pressed to expand outwards; and when the device is in an unoperated state, the limiting plate will limit the rotation of the outward pushing plates to ensure that the outward pushing plates are in an outwardly inclined state.

[0007] Preferably, the outward expansion mechanism includes: A rotating component, which is fixedly connected to the side wall of the outward pushing plate through a pushing member. The pushing member includes a second fixing plate fixedly connected to the side wall of the outward pushing plate. A V-shaped spring piece is fixedly connected to the side wall of the second fixing plate. A pushing component, which is rotatably connected to the inner wall of the outward pushing plate through a pressure member. The pressure member includes a rotating square plate rotatably connected to the inner wall of the outward pushing plate. A sliding long plate is slidably connected to the inner wall of the rotating square plate. An L-shaped rotating rod is fixedly connected to the top of the sliding long plate. Among them, the end of the V-shaped spring piece away from the second fixing plate is rotatably connected to the side wall of the rotating square plate. And when in the unoperated state, since the V-shaped spring piece is always in a compressed state, when the restriction outside the rotating square plate disappears, at this time the V-shaped spring piece will generate a relatively large mechanical force, forcing the rotating square plate to open outwards, forcing the L-shaped rotating rod and the rotating square plate to rotate outwards.

[0008] Preferably, the contraction component includes a first spring fixedly connected to the outer wall of the telescopic rod; Among them, when the abrasive belt changes due to the deformation of the bottom linkage mechanism and the outward expansion mechanism, the telescopic rod will produce corresponding shrinkage deformation. At this time, the first spring will be compressed to store potential energy and ensure that the abrasive belt is in a tight state during operation.

[0009] Preferably, the moving component includes a torsion spring fixedly connected to the inner wall of the rotating rod, and one end of the torsion spring away from the rotating rod is fixedly connected to the side wall of the first fixed rod; Among them, when the worker drives the first fixing plate and the moving component downward through the handle, the roller will always contact the outer wall of the wall panel to ensure that the device can slide along the outer wall of the wall panel.

[0010] Preferably, the outward expansion component includes a reset spring fixedly connected between the two outer pushing plates; Among them, when the outer pushing plates open outward, the reset spring will be compressed to produce deformation and store potential energy to provide power for subsequent reset.

[0011] Preferably, the control component includes a sliding square tube fixedly connected to the side wall of the outer pushing plate. A beveled skateboard is slidably connected to the inner wall of the sliding square tube, and a second spring is fixedly connected to the side wall of the beveled skateboard; Among them, as the outer pushing plate is pressed and moves outward, at this time, as the outer pushing plate rotates upward, since the second fixed rod is in a fixed state, the second fixed rod will push the push rod along the inner wall of the support block, forcing the other end of the push rod to press the bevel of the beveled skateboard, so that the beveled skateboard moves away from the outer wall of the rotating square plate and releases the restriction on the rotating square plate.

[0012] Preferably, the rotating component includes a rotating round rod fixedly connected to one end of the outer pushing plate away from the support frame; Among them, the potential energy released by the two V-shaped spring pieces is much greater than the pressure released by the four first springs.

[0013] The pushing component includes a third spring fixedly connected to the bottom of the sliding long plate, and one end of the third spring away from the sliding long plate is fixedly connected to the inner wall of the rotating square plate; Among them, in the non-working state, the third spring is in a semi-compressed state. When the rotating square plate rotates outward, if the inner groove of the wall panel is thin, the L-shaped rotating rod will be pressed and slide downward along the inner wall of the rotating square plate. If the groove of the wall panel is thick, the third spring will push the L-shaped rotating rod upward, forcing the inner wall of the L-shaped rotating rod to always closely adhere to the inner wall of the groove of the wall panel.

[0014] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic that the inner wall corners of the T-shaped groove are mostly ninety degrees. A linkage mechanism and an outward expansion mechanism are arranged inside the device. When the device is on the inner wall of the wire groove, with the application of the top pressure, at this time, the fixed block will force the two outer push plates to rotate outward. As the outer push plates rotate, the outer push plates will drive the inclined plane slide plate and the sliding square tube to approach the second fixed rod, causing the end of the push rod to press the inner inclined plane of the inclined plane slide plate, forcing the inclined plane slide plate to approach the direction of the second spring. At this time, the inclined plane slide plate will move away from the outer wall of the rotating square plate, thereby releasing the restriction of the inclined plane slide plate on the rotating square plate. Driven by the V-shaped spring piece, the rotating square plate drives the L-shaped rotating rod to expand outward synchronously and produces a "click" sound, causing the linkage mechanism and the outward expansion mechanism to change from Figure 1 the state to Figure 2 the state. At this time, the L-shaped rotating rod will press the abrasive belt tightly against the inside of the T-shaped wire groove of the wall panel. At this time, the driving motor drives the abrasive belt to rotate through the driving cylinder, forcing the abrasive belt to fully rub the inner wire groove of the wall panel. Through the application of the above components, the polishing efficiency of the device on the inner wall of the wire groove is increased; (2) The present invention utilizes the characteristic that the above V-shaped spring piece drives the rotating square plate and the L-shaped rotating rod to rotate outward. When the V-shaped spring piece generates a strong push, at this time, the V-shaped spring piece will generate Figure 9 the thrust in the G direction in . This pressure will form a relatively stable triangle with the rotating square plate and the outer push plate. Both of the two first springs in the device will effectively absorb the mechanical power generated by the two groups of first springs, ensuring that during the process of the device moving horizontally along the inner wall of the wire groove, the staff does not need to always maintain a downward pressing posture. While applying a relatively small downward pressure, the device can be driven to move horizontally left and right; BRIEF DESCRIPTION OF THE DRAWINGS

Before use, first place the linkage mechanism 2 into the groove of the wallboard, and then the worker presses it forcefully, forcing the linkage mechanism 2 to deform; An outward expansion mechanism 3 is fixedly connected to the inner wall of the linkage mechanism 2 and is used to generate deformation inside the groove of the wallboard and fill the grinding belt 18 into the groove of the wallboard; Among them, before use, the staff places the device into the groove of the wallboard through the handle 13, then presses the handle 13, causing the linkage mechanism 2 to deform and the grinding belt 18 to fill the inner groove of the wallboard. Then, the driving motor 16 drives the grinding belt 18 to rotate inside the groove of the wallboard through the driving cylinder 17.

[0020] The driving mechanism 1 includes: A contraction component 11, and the contraction component 11 is fixedly connected to the side wall of the first fixing plate 14 through an extrusion part; The extrusion part includes four telescopic rods 111 fixedly connected to the side wall of the first fixing plate 14.

A rotating rod 122 is rotatably connected to the side wall of the first fixing rod 121. The end of the rotating rod 122 away from the first fixing rod 121 is rotatably connected to a roller 123; Among them, the four telescopic rods 111 are grouped in pairs, and the two in each group are in an opposing state, ensuring that the two rotating columns 112 are in a rotating state with the outer wall of the grinding belt 18; Before use, first place the wallboard on the ground. Then, the staff holds the handle 13 and ensures that the linkage mechanism 2 is inserted into the T-shaped wire groove of the wallboard. Then, press the handle 13 forcefully, forcing the entire device to be pressed downward. After hearing a "click" sound inside, continue to press the device until it can no longer move downward. Then, turn on the power of the driving motor 16, and the staff pushes the device to move horizontally along the direction of the wire groove to complete the basic polishing process.

[0021] The linkage mechanism 2 includes: An outward expansion component 21, which is fixedly connected to the bottom of the fixed block 15 by pressure fixation; The pressure component includes a support frame 211 fixedly connected to the bottom of the fixed block 15. At the inner wall of the bottom of the support frame 211, two rotating columns 212 are rotatably connected. At the outer walls of the two rotating columns 212, an outer pushing plate 213 is fixedly connected. At the inner wall of the bottom of the support frame 211, a limiting plate 214 is fixedly connected; A control component 22, which is fixedly connected to the inner wall of the support frame 211 through a linkage member; The linkage member includes a second fixed rod 221 fixedly connected to the inner wall of the support frame 211. At the outer wall of the outer pushing plate 213, a support block 223 is fixedly connected. Inside the through hole of the support block 223, a pushing rod 222 is slidably connected. One end of the pushing rod 222 is rotatably connected to the side wall of the second fixed rod 221; Wherein, when the grip 13 drives the support frame 211 to press downward, at this time the two outer pushing plates 213 will be pressed to expand outwards; and in the non-working state of the device, the limiting plate 214 will limit the rotation of the outer pushing plate 213 to ensure that the outer pushing plate 213 is in a state of tilting outwards.

[0022] The outward expansion mechanism 3 includes: A rotating component 31, which is fixedly connected to the side wall of the outer pushing plate 213 through a pushing member; The pushing member includes a second fixing plate 311 fixedly connected to the side wall of the outer pushing plate 213. At the side wall of the second fixing plate 311, a V-shaped spring piece 312 is fixedly connected; A pushing component 32, which is rotatably connected to the inner wall of the outer pushing plate 213 through a pressure component; The pressure component includes a rotating square plate 321 rotatably connected to the inner wall of the outer pushing plate 213. Inside the inner wall of the rotating square plate 321, a sliding long plate 323 is slidably connected. At the top of the sliding long plate 323, an L-shaped rotating rod 324 is fixedly connected; Wherein, one end of the V-shaped spring piece 312 away from the second fixing plate 311 is rotatably connected to the side wall of the rotating square plate 321. And in the non-working state, since the V-shaped spring piece 312 is always in a compressed state, when the restriction outside the rotating square plate 321 disappears, at this time the V-shaped spring piece 312 will generate a relatively large mechanical force, forcing the rotating square plate 321 to open outwards, forcing the L-shaped rotating rod 324 and the rotating square plate 321 to rotate outwards; For the convenience of installation by using the groove of the wall panel, most of the grooves or wire grooves are in a mutually communicating state. After the inner part of the wire groove is polished, the staff horizontally push the device to the edge of the plate, presenting as Figure 2state, and after the device continues, at this time the reset spring 215 will drive the outer push plates 213 at both ends to reset. When polishing the subsequent wire grooves, the staff also needs to first press the L-shaped rotating rods 324 at both ends and rotate the square plate 321, so that the above two components return from Figure 9 the state to Figure 6 the state.

[0023] Example two, please refer to Figures 2 - 9 , the present invention is a polishing mechanism for wall panel processing that is easy to adjust. On the basis of Example one, the contraction component 11 includes a first spring 113 fixedly connected to the outer wall of the telescopic rod 111; Among them, when the grinding belt 18 changes due to the deformation of the bottom linkage mechanism 2 and the outward expansion mechanism 3, the telescopic rod 111 will undergo corresponding contraction deformation. At this time, the first spring 113 will be compressed to store potential energy and ensure that the grinding belt 18 is in a taut state during operation; Utilizing the characteristic that the inner wall corners of the T-shaped groove are mostly ninety degrees, a linkage mechanism 2 and an outward expansion mechanism 3 are arranged inside the device. When the device is at the inner wall of the wire groove, with the application of the top pressure, the fixed block 15 will force the two outer push plates 213 to rotate outward at this time. As the outer push plates 213 rotate, the outer push plates 213 will drive the inclined plane slide plate 225 and the sliding square tube 224 to approach the second fixed rod 221, so that the end of the push rod 222 squeezes the inner inclined plane of the inclined plane slide plate 225, forcing the inclined plane slide plate 225 to approach the direction of the second spring 226. At this time, the inclined plane slide plate 225 will move away from the outer wall of the rotating square plate 321, thereby removing the restriction of the inclined plane slide plate 225 on the rotating square plate 321.

[0024] The moving component 12 includes a torsion spring 124 fixedly connected to the inner wall of the rotating rod 122, and one end of the torsion spring 124 away from the rotating rod 122 is fixedly connected to the side wall of the first fixed rod 121; Among them, when the worker drives the first fixing plate 14 and the moving component 12 to move downward through the handle 13, the roller 123 will always be in contact with the outer wall of the wall panel to ensure that the device can slide along the outer wall of the wall panel; Driven by the V-shaped spring piece 312, the rotating square plate 321 drives the L-shaped rotating rods 324 to expand outward synchronously and produce a "click" sound, so that the linkage mechanism 2 and the outward expansion mechanism 3 change from Figure 1 the state to Figure 2 the state. At this time, the L-shaped rotating rods 324 will squeeze the grinding belt 18 against the inside of the T-shaped wire groove of the wall panel. At this time, the driving motor 16 drives the grinding belt 18 to rotate through the driving cylinder 17, which will force the grinding belt 18 to fully rub the inner wire groove of the wall panel. Through the application of the above components, the polishing efficiency of the inner wall of the wire groove by the device is increased.

[0025] The outward expansion component 21 includes a return spring 215 fixedly connected between two outward pushing plates 213; Wherein, when the outward pushing plates 213 expand outwards, the return spring 215 will be compressed and deformed, and store potential energy to provide power for subsequent resetting; Utilizing the characteristic that the above V-shaped spring piece 312 drives the rotating square plate 321 and the L-shaped rotating rod 324 to rotate outwards, when the V-shaped spring piece 312 generates a strong push, at this time the V-shaped spring piece 312 will generate Figure 9 a thrust force in the G direction, and this pressure will form a relatively stable triangle with the rotating square plate 321 and the outward pushing plate 213. And both of the two spring ones 113 in the device will effectively absorb the mechanical power generated by the two groups of spring ones 113, ensuring that during the process of the device moving horizontally along the inner wall of the wire groove, the staff does not need to always maintain a downward pressing posture, and can drive the device to move horizontally left and right while applying a relatively small downward pressure.

[0026] The control component 22 includes a sliding square tube 224 fixedly connected to the side wall of the outward pushing plate 213. A beveled slide plate 225 is slidably connected to the inner wall of the sliding square tube 224, and a spring two 226 is fixedly connected to the side wall of the beveled slide plate 225; Wherein, when the outward pushing plate 213 is pressed and moves outwards, at this time as the outward pushing plate 213 rotates upwards, since the fixed rod two 221 is in a fixed state, at this time the fixed rod two 221 will push the push rod 222 along the inner wall of the support block 223, forcing the other end of the push rod 222 to squeeze the bevel of the beveled slide plate 225, so that the beveled slide plate 225 moves away from the outer wall of the rotating square plate 321 and releases the restriction on the rotating square plate 321.

[0027] The rotating component 31 includes a rotating round rod 313 fixedly connected to one end of the outward pushing plate 213 away from the support frame 211 and rotatably connected; Wherein, the potential energy released by the two V-shaped spring pieces 312 is much greater than the pressure released by the four spring ones 113.

[0028] The pushing component 32 includes a spring three 322 fixedly connected to the bottom of the sliding long plate 323. One end of the spring three 322 away from the sliding long plate 323 is fixedly connected to the inner wall of the rotating square plate 321; Wherein, in the non-working state, the spring three 322 is in a semi-compressed state. When the rotating square plate 321 rotates outwards, if the inner groove of the wall panel is relatively thin, at this time the L-shaped rotating rod 324 will be pressed and slide down along the inner wall of the rotating square plate 321. If the groove of the wall panel is relatively thick, at this time the spring three 322 will push the L-shaped rotating rod 324 to move upwards, forcing the inner wall of the L-shaped rotating rod 324 to always closely adhere to the inner wall of the groove of the wall panel, ensuring that the device can effectively polish wire grooves of different sizes and depths.

[0029] A specific application of this embodiment is as follows: Before using the present invention, first place the wall panel on the ground. Then, the staff holds the grip 13 and ensures that the linkage mechanism 2 is inserted into the T-shaped wire groove of the wall panel. Then, press the grip 13 forcefully to force the entire device to be pressed downward. After hearing the "click" sound inside, continue to press the device until it can no longer move downward. Then, turn on the power of the drive motor 16, and the staff pushes the device to move horizontally along the direction of the wire groove to complete the basic polishing process; Taking advantage of the fact that most of the inner wall corners of the T-shaped groove are ninety degrees, a linkage mechanism 2 and an outward expansion mechanism 3 are provided inside the device. When the device is at the inner wall of the wire groove, with the application of the top pressure, at this time, the fixed block 15 will force the two outer push plates 213 to rotate outward. As the outer push plate 213 rotates, the outer push plate 213 will drive the inclined plane slide plate 225 and the sliding square tube 224 to approach the second fixed rod 221, causing the end of the push rod 222 to press the inner inclined plane of the inclined plane slide plate 225, forcing the inclined plane slide plate 225 to approach the direction of the second spring 226. At this time, the inclined plane slide plate 225 will move away from the outer wall of the rotating square plate 321, thereby removing the restriction of the inclined plane slide plate 225 on the rotating square plate 321. Driven by the V-shaped spring piece 312, the rotating square plate 321 drives the L-shaped rotating rod 324 to expand outward synchronously and produces a "click" sound, causing the linkage mechanism 2 and the outward expansion mechanism 3 to change from Figure 1 the state of Figure 2 to the state of At this time, the L-shaped rotating rod 324 presses the abrasive belt 18 tightly against the inside of the T-shaped wire groove of the wall panel. At this time, the drive motor 16 drives the abrasive belt 18 to rotate through the drive cylinder 17, forcing the abrasive belt 18 to fully rub the inner wire groove of the wall panel. Through the application of the above components, the polishing efficiency of the device on the inner wall of the wire groove is increased; Figure 9 Taking advantage of the above characteristics that the V-shaped spring piece 312 drives the rotating square plate 321 and the L-shaped rotating rod 324 to rotate outward, when the V-shaped spring piece 312 generates a strong push, at this time, the V-shaped spring piece 312 will generate Taking advantage of the feature that the above L-shaped rotating rod 324 can slide along the inner wall of the rotating square plate 321, a third spring 322 is provided inside the device. When the third spring 322 is in an unoperated state, it is in a semi-compressed state. When the rotating square plate 321 rotates outward, if the inner groove of the wall panel is thin, at this time the L-shaped rotating rod 324 will be pressed and slide downward along the inner wall of the rotating square plate 321. If the groove of the wall panel is thick, at this time the third spring 322 will push the L-shaped rotating rod 324 upward, forcing the inner wall of the L-shaped rotating rod 324 to always closely adhere to the inner wall of the groove of the wall panel, ensuring that the device can effectively polish wire grooves of different sizes and depths.

[0030] For the convenience of installation, most of the grooves or wire grooves in the wall panel are in a communicating state. After the inner part of the wire groove is polished, the worker horizontally pushes the device to the edge of the plate, presenting a state as shown in Figure 2 . And when the device continues to move, at this time the reset spring 215 will drive the outer push plates 213 at both ends to reset. When polishing the subsequent wire grooves, the worker also needs to first press the L-shaped rotating rods 324 and the rotating square plate 321 at both ends, so that the above two components are restored from the state shown in Figure 9 to the state shown in Figure 6 .
