Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0056] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0057] In some embodiments of this application, a grinding machine is proposed, comprising:

[0058] First base component 100;

[0059] The second base component 200 is slidably connected to the first base component 100;

[0060] Sanding belt unit 300, used for sanding sheet metal;

[0061] The grinding mechanism 400 is assembled onto the second base component 200 and connected to the sanding belt unit 300. When in operation, it can drive the sanding belt unit 300 to move and grind the plate material conveyed by the conveyor bed.

[0062] The grinding mechanism 400 provides the power for the movement of the sanding belt unit 300. The grinding mechanism 400 is connected to the sanding belt unit 300 and can drive the sanding belt unit 300 to move, thereby performing corresponding grinding operations on the board through the sanding belt unit 300.

[0063] In some embodiments of this application, the abrasive belt unit 300 includes:

[0064] The sanding belt frame and the sanding belt rollers symmetrically arranged on the sanding belt frame, with the two ends of the sanding belt wound around the two sanding belt rollers respectively.

[0065] The grinding mechanism 400 includes a grinding power mechanism and a sanding pad, and the grinding power mechanism drives the sanding pad to move.

[0066] The sanding pad is placed on the sanding belt between the two sanding rollers and is connected and fixed to the sanding belt frame.

[0067] The grinding power mechanism includes:

[0068] There are two eccentric grinding mechanisms arranged side by side.

[0069] Each eccentric grinding mechanism includes: a rotating component 820 having an eccentric portion;

[0070] The drive mechanism 810 is connected to the rotating component 820 and drives the rotating component 820 to rotate.

[0071] The eccentric parts of both eccentric grinding mechanisms are connected to the sanding pad, and the sanding pad is connected to the sanding belt frame.

[0072] The drive mechanism 810 is configured to include a drive motor and two reducers. The two reducers are respectively connected to two rotating parts 820. The two reducers are connected to each other through a connecting shaft. The drive motor and one of the reducers are connected in a transmission connection.

[0073] When the belt sanding device is working, the two eccentric grinding mechanisms move synchronously, driving the sanding pad, sanding belt frame, sanding roller and sanding belt connected to it to perform circumferential translation to sand the board.

[0074] The rotating component 820 includes a rotating main body and an eccentric part, with the axis of the rotating main body and the axis of the eccentric part offset by a certain distance.

[0075] The rotating main body is the rotating main body segment, and the eccentric part is the eccentric shaft segment.

[0076] During connection, the rotating main body section and the drive mechanism 810 are connected, and a connecting sleeve 830 is sleeved on the outer side of the eccentric part. A fixing plate 840 is fixedly connected to the bottom of the connecting sleeve 830.

[0077] The fixing plate 840, sanding pad, and sanding belt holder are fixed together by screws.

[0078] The grinding mechanism 400 is assembled onto the second base component 200. At the same time, the grinding mechanism 400 is connected to the sanding belt unit 300, so that both the sanding belt unit 300 and the grinding unit are connected to the second base component 200.

[0079] The second base component 200 is slidably connected to the first base component 100. When the second base component 200 slides relative to the first base component 100, it can correspondingly drive the sanding belt unit 300 and the grinding mechanism 400 connected above it to slide synchronously, so that the sanding belt unit 300 and the grinding mechanism 400 can slide out relative to the first base component 100.

[0080] In this way, when the relevant components in the sanding belt unit 300 or the grinding mechanism 400 need to be repaired or disassembled, it is only necessary to slide the second base component 200 out relative to the first base component 100 and perform the corresponding maintenance operation in the outer area of ​​the grinding machine. It is no longer limited by the maintenance space and the maintenance operation is more convenient and faster.

[0081] Since there is no need for staff to climb onto the first base component 100 to perform maintenance or related work, potential safety hazards caused by climbing for maintenance are avoided.

[0082] In some embodiments of this application, in order to enable the second base component 200 to automatically slide out relative to the first base component 100 during the maintenance of the grinding machine, the grinding machine is also provided with a sliding drive device 510 and a transmission device 520 connected to the sliding drive device 510.

[0083] The transmission device 520 is arranged on the second base component 200 and the first base component 100 and is connected to the sliding drive device 510. When the sliding drive device 510 is activated, the transmission device 520 drives the second base component 200 to slide out relative to the first base component 100.

[0084] The sliding drive device 510 provides sliding power. The sliding drive device 510 can be a motor and a reducer. The motor and the reducer are connected, and the reducer has an output end.

[0085] The transmission device 520 includes a transmission rack and a transmission gear, the transmission gear being connected to the output end of the reducer, and the transmission gear and the transmission rack meshing.

[0086] In the configuration, the transmission rack is mounted on the second base component 200 and arranged along the length of the second base component 200.

[0087] When the motor rotates, it drives the reducer to run. The output end of the reducer drives the transmission gear to rotate. The transmission gear meshes with the transmission rack, causing the transmission rack and the second base component 200 connected to the transmission rack to slide relative to the first base component 100.

[0088] By setting up a sliding drive device 510 in conjunction with a transmission device 520, the second base component 200 can be automatically slid out relative to the first base component 100, achieving automatic sliding without the need for manual operation and saving manpower.

[0089] In some embodiments of this application, a sliding track 210 is provided on at least one side of the second base component 200, and a sliding roller 110 that cooperates with the sliding track 210 is provided on the first base component 100.

[0090] To enable the second base component 200 to slide smoothly relative to the first base component 100, sliding tracks 210 are provided on both sides of the second base component 200, and two sets of rolling rollers are also provided on the first base component 100 to cooperate with the two sliding tracks 210 respectively.

[0091] The sliding track 210 and the sliding roller 110 work together to guide the sliding of the second base component 200, so that it does not deviate from its direction during the sliding process.

[0092] The sliding roller 110 is provided with a roller groove, and the sliding track 210 is inserted into the roller groove and slides along the roller groove. In the installation, multiple sliding rollers 110 are provided and arranged along the length direction of the second base component 200.

[0093] The sliding track 210 is inserted into a plurality of sliding rollers 110 to slide relative to the sliding rollers 110.

[0094] Meanwhile, since the sliding rail 210 is inserted into the roller groove, the movement of the sliding rail 210 can be limited by the upper and lower walls of the roller groove.

[0095] In some embodiments of this application, the grinding mill further includes:

[0096] An anti-warping component is disposed on the first base component 100 and pressed onto the second base component 200, and is in rolling connection with the second base component 200.

[0097] When the second base component 200 is pulled outward relative to the first base component 100, as the outward portion of the second base component 200 becomes longer, the weight of its outer portion will become heavier and heavier. In order to prevent the second base component 200 from tilting up at one end due to the uneven weight at both ends during the pulling process, anti-warping components are arranged on the first base component 100. These components can be pressed onto the second base component 200 to prevent it from tilting up and ensure the normal sliding out of the second base component 200.

[0098] When the anti-warping component is installed, it is pressed onto the top surface of the second base component 200 and rolled between the second base component 200, so that the friction between it and the second base component 200 is rolling friction. In this way, when the second base component 200 slides out, it can both ensure the pressing and limiting of the second base component 200 and reduce the friction between it and the second base component 200, ensuring that the second base component 200 slides out smoothly.

[0099] In some embodiments of this application, the first base component 100 includes a first end 120 and a second end 130 disposed opposite to the first end 120.

[0100] The second base component 200 is slidably pulled out relative to the first base component 100 along the direction from the first end 120 to the second end 130, and the anti-warping component is disposed near the second end 130.

[0101] As the second base member 200 slides from the first end 120 to the second end 130, continuing from the first base member 100, it continuously extends out from the second end 130 and the length of the extension from the second end 130 continuously increases. That is, the length of the unsupported part in the outer region continuously increases. By placing the anti-warping component near the position of the second end 130, the part of the second base member 200 on the first base member 100 can be pressed tightly, thereby preventing it from warping.

[0102] In some embodiments of this application, the anti-warping component includes:

[0103] The anti-warping seat 610, fixed on the first base member 100, includes:

[0104] Main support part 611; and

[0105] The connecting part 612 is vertically connected to the main body support part 611;

[0106] The rolling pressing assembly is horizontally mounted on the connecting part 612 and extends toward the second base member 200.

[0107] In some embodiments of this application, the rolling pressing component includes:

[0108] Shaft 620 is inserted into the connecting part 612;

[0109] A rolling bearing 630 is assembled to the end of the shaft 620 that extends from the connecting part 612 and is used to press onto the second base member 200.

[0110] A first locking part 621 is provided on the shaft body 620, and a retaining ring is locked in the first locking part 621. The retaining ring limits one end of the rolling bearing 630.

[0111] A first stop 622 is provided on the shaft 620 to limit the other end of the rolling bearing 630.

[0112] A second stop 623 is provided on the shaft 620, which abuts against the side of the connecting part 612 near the second base member 200.

[0113] A washer 650 is fitted on the shaft 620, and the washer 650 is attached to the side of the connecting part 612 away from the first base member 100.

[0114] The locking nut assembly 640 is locked and fixed on the shaft 620 to press and fix the washer 650.

[0115] By fixing the shaft 620 to the connecting part 612 and limiting the rolling bearing 630, the second base member 200 can roll relative to the rolling bearing 630 when it moves.

[0116] An clearance groove is provided on the main support part 611 to allow clearance from the locking nut assembly 640 and the washer 650.

[0117] In some embodiments of this application, the grinding machine further includes a first limiting unit, which includes a first limiting member 140 disposed at a first end 120 of the first base component 100 and a first limiting mating member 220 disposed on the second base component 200 and cooperating with the first limiting member 140.

[0118] When the second base component 200 is slid out along the direction from the second end 130 to the first end 120, the distance of its sliding pull-out is limited by the cooperation of the first limiting member 140 on the first base component 100 and the first limiting cooperating member 220 on the second base component 200, so as to prevent the second base component 200 from coming out of the first base component 100.

[0119] The first limiting component 140 is the first limiting block, and the first limiting mating component 220 is the second limiting mating block.

[0120] The first limiting unit includes a second limiting member 150 disposed at the second end 130 of the first base member 100 and a second limiting cooperating member 230 disposed on the second base member 200 and cooperating with the second limiting member 150.

[0121] When the second base component 200 slides and resets along the direction from the first end 120 to the second end 130, the sliding push distance is limited by the cooperation of the second limiting member 150 on the first base component 100 and the second limiting cooperating member 230 on the second base component 200, so as to ensure that the second base component 200 resets quickly.

[0122] In some embodiments of this application, the grinding machine further includes a second limiting unit, which includes a first limiting element disposed at the first end 120 of the first base member 100 and a first limiting sensing element disposed on the second base member 200 and cooperating with the first limiting element.

[0123] The first limit sensor is a first touch switch, and the first limit element is a first touch block that cooperates with the first touch switch.

[0124] The software limit is achieved by the first limit sensor and the first limit element to prevent the second base component 200 from moving in the direction from the first end 120 to the second end 130, thus preventing it from coming out of the first base component 100.

[0125] The second limiting unit includes a second limiting element disposed at the second end 130 of the first base component 100 and a second limiting sensing element disposed on the second base component 200 and cooperating with the second limiting element.

[0126] The second limit sensor is a second touch switch, and the second limit element is a second touch block that cooperates with the second touch switch.

[0127] The second limiting sensor and the second limiting element work together to achieve software limiting of the second base component 200 when it moves along the direction from the second end 130 to the first end 120.

[0128] The first limiting unit can mechanically limit the movement of the second base component 200, and the second limiting unit can software limit the movement of the second base component 200. The mechanical and software limiting work together to ensure the movement of the second base component 200 on the first base component 100.

[0129] In some embodiments of this application, the first base component 100 includes:

[0130] There are two longitudinal beams, each 160mm long, arranged at a certain interval.

[0131] Two transverse beams 170 are provided and interconnected with the two longitudinal beams 160, forming a first clearance section between the longitudinal beams 160 and the transverse beams 170.

[0132] One of the transverse beams 170 has its two ends connected to one end of each of the two longitudinal beams 160, and the other transverse beam 170 has its two ends connected to the other ends of the two longitudinal beams 160.

[0133] Two extension plates 171 are provided, which are respectively connected to two transverse beams 170. The sliding rollers 110 are provided on the two extension plates 171. The anti-warping component and the sliding drive device 510 are provided on one of the extension plates 171.

[0134] The first clearance part is the first clearance hole, and the first clearance hole is a square hole.

[0135] The second base component 200 is provided with a second clearance portion 240, which is connected to the first clearance portion. The second clearance portion 240 is a second clearance hole, which is located in the same position as the first clearance hole and is connected to it.

[0136] The first and second clearance holes can be used to avoid the sanding belt unit 300 and the grinding mechanism 400.

[0137] The second base component 200 includes: a second base plate 250;

[0138] And the second support column 260, of which two are provided and symmetrically arranged on the second base plate 250;
