Description

Technical Field

[0001] This invention relates to the field of flatbed press grinding equipment, specifically to a brake pad grinding machine for a double steel belt continuous flatbed press. Background Technology

[0002] Currently, double-strand continuous flatbed presses used for producing engineered wood panels consist of an upper press, a lower press, and continuously circulating steel belts that wrap around both the upper and lower presses. The upper and lower steel belts are driven by drive rollers. Brake pads are installed on the drive rollers to increase the coefficient of friction with the steel belts. With prolonged operation, the brake pads on the drive rollers wear down, requiring replacement. The replaced brake pads have a height difference, which, over time, wears down the steel belt surface, causing scratches and affecting the uneven thickness and quality of the panels. Therefore, newly replaced brake pads need to be polished on-site. However, the height difference of the newly replaced brake pads causes the belt on the polisher to slip off from the drive roller or shift during polishing, affecting the polishing effect and potentially damaging the polisher. Summary of the Invention

[0003] To overcome the above-mentioned defects, embodiments of the present invention provide a brake pad grinding machine for a double steel belt continuous flat press, which solves the technical problem that the grinding belt is prone to slipping or shifting from the drive wheel when the grinding machine moves along the drive roller axis during the existing double steel belt continuous flat press brake pad grinding process, resulting in poor grinding effect.

[0004] According to one aspect, at least one embodiment of the present invention provides a brake pad grinding machine for a double-belt continuous flat press, used for grinding brake pads on the drive roller of the flat press, comprising: The mounting plate is detachably mounted on the flat press frame; A cross slide is mounted on the mounting plate and located on one side of the drive roller, and the cross slide is provided with a movable plate; A grinding component is disposed on the movable plate. The grinding component includes a drive wheel and a grinding belt driven by the drive wheel. The grinding component can approach the drive roller under the drive of the movable plate of the cross slide table, and move along the axial direction of the drive roller under the drive of the movable plate of the cross slide table, so as to grind the brake pads on the drive roller by the grinding belt. An anti-detachment mechanism is provided on the movable plate of the cross slide table. The anti-detachment mechanism has two side stop rollers, which are located on both sides of the grinding belt to limit the two side edges of the grinding belt.

[0005] Optionally, the grinding element further includes: A driver is mounted on the movable plate and is capable of moving along with the movable plate. The drive wheel is located at the output end of the driver. A lifting bracket is mounted on the housing of the driver. A driven wheel is rotatably mounted on the upper end of the lifting bracket. The grinding belt is wound around the driving wheel and the driven wheel. The lifting bracket is used to adjust the distance between the driven wheel and the driving wheel to tension or loosen the grinding belt.

[0006] Optionally, the lifting bracket includes: A fixing plate is detachably mounted on the housing of the driver, and the anti-detachment strap mechanism is mounted on the fixing plate; A lifting rod is mounted on the fixed plate, and a mounting base is hinged to the upper end of the lifting rod. The driven wheel is rotatably mounted on the mounting base. A fastening bolt passes through the lifting rod and is threadedly connected to the mounting base. The fastening bolt is used to lock the mounting base onto the lifting rod.

[0007] Optionally, the anti-slip strap mechanism includes: A frame is mounted on the fixed plate. A sliding frame is slidably mounted on the side of the frame near the grinding belt. Two pressure rollers are rotatably mounted on the sliding frame, and the two pressure rollers press against the two side edges of the grinding belt respectively. A reversing assembly is mounted on the frame. The reversing assembly includes a base, a reversing wheel, a first slide, and a second slide. The reversing wheel is rotatably mounted on the base. The first slide is located above the base and rolls with the reversing wheel. The first slide is fixedly connected to the sliding frame and moves horizontally under the drive of the sliding frame. The second slide is located below the base and rolls with the reversing wheel, and can run in the opposite direction to the first slide under the action of the reversing wheel. A connecting frame is disposed on the second slide block, and the connecting frame surrounds both sides of the grinding belt. Two side guide rollers are rotatably disposed on the connecting frame. The area between the side guide rollers and the pressure roller is the grinding area. The grinding belt in the grinding area is used to contact the brake pad and grind the brake pad. When the grinding belt in the grinding area shifts, the pressure roller can be pushed by the grinding belt to drive the first slide block to move laterally, so that the second slide block moves in the opposite direction under the action of the first slide block, and drives the grinding belt to reset.

[0008] Optionally, the seat body is provided with a sliding groove, and the reversing wheel is rotatably disposed in the sliding groove. The reversing wheel is a gear. The first slide has a first rack portion, and the second slide has a second rack portion. Both the first rack portion and the second rack portion mesh with the reversing wheel.

[0009] Optionally, the first slide is provided with a connecting rod, and the first slide is fixedly connected to the sliding frame through the connecting rod; the connecting frame is L-shaped, and the connecting frame has a longitudinal rod and a transverse rod, the longitudinal rod is used to connect with the second slide, and the transverse rod is used to install the two side rollers.

[0010] Optionally, the pressure roller is truncated cone-shaped, with its smaller diameter end close to the sliding frame.

[0011] Optionally, the cross slide includes: A transverse slide is mounted on the frame; The feed slide is slidably mounted on the transverse slide, and the moving plate is slidably mounted on the feed slide.

[0012] Optionally, the rotation direction of the drive wheel is opposite to that of the drive roller.

[0013] Optionally, several brake pads can be detachably mounted on the outer peripheral wall of the drive roller, with two axially adjacent brake pads arranged in a staggered manner.

[0014] The beneficial effects of this invention are as follows: In this invention, when grinding is required, the mounting plate is fixed to the frame, the cross slide is activated, and the moving plate of the cross slide moves the grinding component closer to the drive roller, causing the grinding belt to contact the brake pads. The drive wheel drives the grinding belt to run, and simultaneously the cross slide moves the grinding component along the drive roller axially to grind the brake pads at different positions. When the grinding belt deviates from the drive roller, the side guard rollers on both sides push the grinding belt back onto the drive roller. This prevents the grinding belt from slipping or shifting off from the drive roller when the grinder moves along the drive roller axially, ensuring the grinding effect, preventing damage to the grinder, ensuring that newly replaced brake pads are ground flat, reducing steel belt wear, and ensuring uniform plate thickness and quality.

[0024] like Figures 1-9 The diagram illustrates a brake pad grinding machine for a double-strand continuous flat press according to an embodiment of the present invention. It is used to grind several brake pads 3 mounted on the drive roller 2 of the flat press. The grinding machine includes a mounting plate 4, a cross slide 5, a grinding element 6, and an anti-detachment mechanism 7 mounted on the grinding element 6 to prevent the grinding belt 62 from deviating from the drive wheel 61. The mounting plate 4 is detachably mounted on the flat press frame 1. The cross slide 5 is disposed on the mounting plate 4 and located on one side of the drive roller 2. The grinding element 6 is mounted on a movable plate 53 of the cross slide 5. The grinding element 6 includes a drive wheel 61 and a grinding belt 62 driven by the drive wheel 61. The grinding element 6 can move closer to or further away from the drive roller 2 under the action of the cross slide 5 and can move axially along the drive roller 2 under the drive of the drive roller 2. The anti-detachment mechanism 7 is mounted on the grinding element 6, with its two side guide rollers 71 located on both sides of the grinding belt 62.

[0025] In the above scheme, when grinding is required, the mounting plate 4 is fixed to the frame 1 by a steel frame or bolts. Then, the cross slide 5 is started. The lateral movement and feed of the cross slide 5 can be driven by a screw motor and manually. The cross slide 5 drives the grinding piece 6 closer to the drive roller 2, so that the grinding belt 62 contacts the brake pad 3. The drive wheel 61 drives the grinding belt 62 to run. At the same time, the cross slide 5 drives the grinding piece 6 to move axially along the drive roller 2 to grind the brake pad 3 at different positions. When the grinding belt 62 deviates from the drive wheel 61, the side guard rollers 71 on both sides will push the grinding belt 62 back onto the drive wheel 61. This can prevent the grinding belt 62 from slipping or shifting off from the drive wheel 61 when the grinder moves axially along the drive roller 2, ensuring the grinding effect, preventing damage to the grinder, grinding the newly replaced brake pad 3 flat, and reducing steel belt wear.

[0026] Furthermore, the driver 63 of the grinding component 6 is mounted on the movable plate 53 of the cross slide 5 and can move with the cross slide 5. The drive wheel 61 is mounted on the movable end of the driver 63, which serves as the drive motor. The drive motor can not only drive the drive wheel 61 but also change the speed of the drive wheel 61. The lifting bracket 64 is mounted on the housing of the driver 63. A driven wheel 645 is rotatably mounted on the end of the lifting bracket 64 away from the driver 63. The grinding belt 62 is wound around the drive wheel 61 and the driven wheel 645 in sequence. The lifting bracket 64 can adjust the distance between the driven wheel 645 and the drive wheel 61 to tension or loosen the grinding belt 62.

[0027] In the above scheme, before grinding, the distance between the driven wheel 645 and the drive wheel 61 is adjusted by the lifting bracket 64. The distance is increased when the grinding belt 62 needs to be tensioned and decreased when it needs to be loosened. During grinding, the driver 63 drives the drive wheel 61 to rotate, and the drive wheel 61 drives the grinding belt 62 and the driven wheel 645 to run, coordinating with the movement of the cross slide 5 to grind the brake pad 3. The tension of the grinding belt 62 can be flexibly adjusted by the lifting bracket 64 to ensure close contact between the grinding belt 62 and the brake pad 3, improving grinding efficiency and effect, and facilitating the replacement and maintenance of the grinding belt 62.

[0028] Furthermore, the fixing plate 641 of the lifting bracket 64 is detachably mounted on the housing of the driver 63, the anti-slip mechanism 7 is disposed on the fixing plate 641, the lifting rod 642 is mounted on the fixing plate 641, the end of the lifting rod 642 away from the fixing plate 641 is hinged to the mounting base 644, the driven wheel 645 is rotatably mounted on the mounting base 644, and the fastening bolt 643 passes through the mounting base 644 and the lifting rod 642 to fix the two.

[0029] In the above solution, when it is necessary to disassemble or replace the grinding belt 62, the fastening bolt 643 can be loosened first, the mounting base 644 can be rotated through the hinge structure, and the lifting rod 642 can be lowered to remove the grinding belt 62. Then, the mounting base 644 can be flipped upward to change the relative position of the mounting base 644 and the lifting rod 642, and the driven wheel 645 can be replaced or adjusted. After adjustment, the fastening bolt 643 can be tightened to fix the mounting base 644. The flexible adjustment of the position of the driven wheel 645 is achieved through the hinge and the fastening bolt 643, ensuring accurate adjustment of the tension of the grinding belt 62. The structure is simple, the operation is convenient, and it is beneficial to improve the grinding stability.

[0030] Furthermore, the frame 70 of the anti-slip mechanism 7 is mounted on the fixed plate 641. A sliding frame 73 is slidably mounted on the side of the frame 70 near the grinding belt 62. Two pressure rollers 74 are rotatably mounted on the sliding frame 73. The two pressure rollers 74 abut against both sides of the grinding belt 62 respectively. The reversing assembly is mounted on the frame 70. The reversing assembly includes a seat 75, a reversing wheel 79, a first slide 76, and a second slide 77. The first slide 76 and the second slide 77 can move in opposite directions under the action of the reversing wheel 79. The sliding frame 73 is fixedly connected to the first slide 76. The connecting frame 78 is mounted on the second slide 77 and is located on both sides of the drive wheel 61 and the grinding belt 62. Two side guard rollers 71 are rotatably mounted on the connecting frame 78. The area between the pressure rollers 74 and the side guard rollers 71 is the grinding area. The grinding belt 62 in this area is used to contact and grind the brake pads 3.

[0031] In the above scheme, if the grinding belt 62 in the grinding area shifts during grinding, it will push the pressure roller 74 on one side, causing the sliding frame 73 to move laterally. The sliding frame 73 drives the first sliding block 76 to move. Under the action of the reversing component, the second sliding block 77 moves in the opposite direction, driving the connecting frame 78 and the side stop roller 71 to move. The side stop roller 71 pushes the grinding belt 62 back, so that the grinding belt 62 fully contacts the drive wheel 61. This forms a linkage correction mechanism, which can correct the shift of the grinding belt 62 in the early stage. The anti-slip effect is timely and reliable, ensuring the continuous and stable grinding process, improving grinding quality, and reducing the risk of equipment damage.

[0032] Furthermore, a groove 751 is provided on the seat 75, and a reversing wheel 79 is rotatably arranged in the groove 751. The reversing wheel 79 is a gear. The first slide 76 has a first rack portion, and the second slide 77 has a second rack portion. Both the first rack portion and the second rack portion mesh with the gear.

[0033] In the above design, the slide groove 751 is elongated and is a through groove. A reversing wheel 79 is rotatably mounted inside the slide groove 751. The reversing wheel 79 can only rotate on its own axis. A first rack portion is provided on the bottom surface of the first slide block 76 along its length, and a second rack portion is provided on the top surface of the second slide block 77 along its length. Both the first rack portion and the second rack portion mesh with gears. It should be noted that a limiting slide groove 751 is also provided at the bottom of the seat body 75. The second slide block 77 is slidably disposed within the limiting slide groove 751, which prevents the second slide block 77 from falling off. When the sliding frame 73 moves the first slide block 76, the first rack part drives the gear to rotate, and the gear rotation drives the second rack part, causing the second slide block 77 to move in the opposite direction to the first slide block 76, thereby realizing the reverse movement of the side stop roller 71. The reverse movement of the first slide block 76 and the second slide block 77 is realized through the meshing of the gear and rack. The structure is stable, the transmission is precise, and the synchronization of the two movements is guaranteed, thereby improving the response speed and correction effect of the anti-slip belt mechanism 7.

[0034] Furthermore, a connecting rod 72 is provided on the first slide block 76, and the first slide block 76 is connected to the sliding frame 73 through the connecting rod 72; the connecting frame 78 is L-shaped, and the connecting frame 78 has a longitudinal rod body 781 and a transverse rod body 782. The longitudinal rod body 781 is used to connect with the second slide block 77, and the transverse rod body 782 is used to install two side rollers 71.

[0035] In the above scheme, a connecting rod 72 is installed on the first slide block 76. The connecting rod 72 is a long rod. To prevent the long rod from vibrating during grinding, a slide rail for limiting the connecting rod 72 can be set above the seat body 75. A trolley plate with wheels is set near the slide rail on the connecting rod 72 to reduce or eliminate the vibration of the connecting rod 72. The first slide block 76 is connected to the sliding frame 73 through the connecting rod 72. The connecting frame 78 is L-shaped and has a longitudinal rod 781 and a transverse rod 782. The longitudinal rod 781 is connected to the second slide block 77, and the transverse rod 782 is used to install two side guide rollers 71. When the first slide block 76 moves, it drives the sliding frame 73 to slide synchronously through the connecting rod 72. When the second slide block 77 moves, the longitudinal rod 781 drives the transverse rod 782 and the side guide rollers 71 to move, so that the side guide rollers 71 act precisely on both sides of the grinding belt 62. The connecting rod 72 ensures that the sliding frame 73 and the first sliding block 76 are firmly connected and have good synchronization. The L-shaped connecting frame 78 makes the side roller 71 installed in a reasonable position, which can accurately push the grinding belt 62 back and improve the reliability of the anti-slip belt.

[0036] Furthermore, the pressure roller 74 is frustum-shaped, with its smaller diameter end close to the sliding frame 73 and its larger diameter end away from the sliding frame 73.

[0037] In the above scheme, when the grinding belt 62 deviates, it will contact the inclined surface of the pressure roller 74. As the deviation increases, the thrust of the grinding belt 62 on the pressure roller 74 is transmitted along the inclined surface, making it easier to move the sliding frame 73, thereby quickly triggering the anti-detachment mechanism 7. The truncated cone shape makes the pressure roller 74 more sensitive to the deviation of the grinding belt 62, triggering the correction action earlier, reducing the deviation of the grinding belt 62, improving the anti-detachment effect, and at the same time reducing the wear of the pressure roller 74 on the grinding belt 62.

[0038] Furthermore, the transverse slide 51 of the cross slide 5 is mounted on the frame 1, the feed slide 52 is slidably mounted on the transverse slide 51, a movable plate 53 is mounted on the feed slide 52, and the driver 63 is mounted on the movable plate 53.

[0039] In the above scheme, when the grinding part 6 needs to be moved axially along the drive roller 2, the transverse slide 51 drives the feed slide 52, the moving plate 53, and the grinding part 6 to move laterally; when the distance between the grinding part 6 and the drive roller 2 needs to be adjusted, the feed slide 52 drives the moving plate 53 and the grinding part 6 to move closer to or away from the drive roller 2, so that the grinding belt 62 contacts or leaves the brake pad 3. The cross slide 5 enables the grinding part 6 to move smoothly in two directions, meeting the grinding needs of the brake pad 3 at different positions, with precise movement, improving grinding efficiency and the flatness of the brake pad 3.

[0040] Furthermore, the rotation direction of the drive wheel 61 is opposite to the rotation direction of the drive roller 2.

[0041] In the above scheme, the rotation direction of the drive wheel 61 is opposite to that of the drive roller 2. During grinding, the drive roller 2 drives the brake pad 3 to rotate, and the drive wheel 61 drives the grinding belt 62 to rotate in the opposite direction, so that the contact area between the grinding belt 62 and the brake pad 3 forms a reverse relative motion. The reverse rotation increases the relative speed between the grinding belt 62 and the brake pad 3, improves grinding efficiency, makes the surface of the brake pad 3 smoother and flatter, and shortens the grinding time.

[0042] Furthermore, multiple brake pads 3 are detachably mounted on the outer peripheral wall of the drive roller 2, with two adjacent brake pads 3 arranged circumferentially staggered along the axial direction of the drive roller 2. In the above scheme, when installing brake pads 3, the new brake pads 3 are detachably fixed to the drive roller 2, ensuring that axially adjacent brake pads 3 are misaligned. When the grinder grinds the brake pads 3, the misaligned arrangement makes the grinding belt 62 more evenly stressed and the grinding more thorough. The detachable design facilitates the replacement of brake pads 3, and the misaligned arrangement avoids continuous height differences between adjacent brake pads 3, reduces local wear on the grinding belt 62, makes the grinding more uniform, extends the service life of the steel belt, and ensures uniform plate thickness.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
