Description

Technical Field

[0001] This utility model belongs to the technical field of sheet metal processing equipment, specifically, it relates to an improvement in the structure of a grinding machine. Background Technology

[0002] The existing equipment structure for grinding belts is as follows: it is equipped with 3 belt rollers, 2 belt rollers are arranged at the bottom near the belt as driven rollers, and 1 belt roller is arranged at the top as the driving roller. The belt is wound around the 3 belt rollers. The grinding pillow is fixed on the frame and pressed between the 2 belt rollers at the bottom to press the belt into contact with the plate.

[0003] During grinding, the active roller at the top rotates, causing the abrasive belt to move between the active roller and the two driven rollers at the bottom. When it moves to the position of the grinding pillow component, the pressure of the grinding pillow component makes it come into contact with the plate and rub against it.

[0004] This type of grinding method, where the abrasive belt grinds along the conveying direction of the board, will create multiple vertical lines on the surface of the board, making the surface cleanliness of the board unable to meet the user's needs.

Therefore, they should not be construed as limitations on this utility model.

[0072] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection.

[0073] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0074] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0075] In some embodiments of this application, a grinding machine is proposed, comprising:

[0076] 100 racks;

[0077] The conveyor bed, located below the frame 100, is used to convey the sheet metal.

[0078] The grinding machine is supported by a frame 100 and positioned above the conveyor bed. The plates continuously fed from the conveyor bed can be ground by the grinding machine located above.

[0079] In some embodiments of this application, the grinding machine includes: a sanding belt unit 200 and a grinding unit 300. The grinding unit 300 is used to drive the sanding belt unit 200 to move. The sanding belt unit 200 is mainly used for grinding. The sanding belt unit 200 includes: a sanding belt frame 210 and a sanding belt roller 220 assembled on the sanding belt frame 210.

[0080] The grinding unit 300 includes a grinding pillow component 400, which can be pressed onto the sanding belt 240 and adsorbed onto the sanding belt 240 and drive the sanding belt 240 to move.

[0081] In some embodiments of this application, two sanding belt rollers 220 are provided and symmetrically arranged on the sanding belt frame 210, with the axes of the two sanding belt rollers 220 being parallel to each other and in the same horizontal plane.

[0082] The sanding belt 240 is wound around two sanding rollers 220 at both ends.

[0083] When selecting, a longer sanding belt 240 roll can be used, which is partially stored by being wound onto two sanding belt rollers 220 respectively, thereby increasing the length of the sanding belt 240 used for grinding.

[0084] The belt abrasive drive mechanism 230 is used to drive two belt abrasive rollers 220 to rotate in order to perform the winding and unwinding of the belt abrasive 240.

[0085] When the drive unit operates, it drives two sanding belt rollers 220 to operate synchronously. One sanding belt roller 220 performs a winding motion, while the other sanding belt roller 220 performs an unwinding motion. The synchronous winding and unwinding of the two sanding belt rollers 220 ensures that the sanding belt 240 between the two sanding belt rollers 220 can always be kept taut, thus ensuring the effect of subsequent grinding.

[0086] The abrasive belt 240 is arranged such that one end is wound around one abrasive belt roller 220 multiple times, and the other end is wound around another abrasive belt roller 220 multiple times. This structure allows the portion of the abrasive belt 240 participating in grinding below the grinding pillow component 400 to be replaced by continuous unwinding and rewinding operations after the abrasive belt 240 wears out. Compared with the existing technology of fixed-length winding arrangement of the abrasive belt 240, this increases the length of the abrasive belt 240 participating in grinding. The abrasive belt 240 can be recycled and unwound for repeated use, reducing the replacement cycle of the abrasive belt 240 and improving production efficiency.

[0087] The grinding unit 300 is assembled onto the frame 100 and includes:

[0088] Two eccentric grinding mechanisms 310 are provided and arranged side by side. Each of the eccentric grinding mechanisms 310 includes:

[0089] The rotating component 311 has an eccentric portion 3111;

[0090] The drive mechanism 320 is connected to the rotating component 311 and drives the rotating component 311 to rotate.

[0091] In the specific arrangement, the two eccentric grinding mechanisms 310 are arranged vertically.

[0092] The rotating component 311 is a rotating shaft 540, which is connected to the drive mechanism 320.

[0093] When the drive mechanism 320 is activated, it can correspondingly drive the rotating component 311 connected to it and the eccentric part 3111 above it to rotate.

[0094] To ensure the synchronization of the two rotating parts 311, the drive mechanism 320 is configured to include a drive motor 321 and two reducers 322. The two reducers are respectively connected to the two rotating parts 311, and the two reducers are connected to each other through a connecting shaft 740. The drive motor 321 is connected to one of the reducers in a transmission connection.

[0095] The grinding pillow component 400 is pressed onto the sanding belt 240 portion located between the two sanding belt rollers 220, and is connected to the sanding belt frame and the grinding unit 300.

[0096] During grinding, the grinding unit 300 operates, driving the grinding pillow component 400 connected to it and the sanding belt unit 200 connected to the grinding pillow component 400 to perform circumferential translation to grind the board.

[0097] When the two eccentric grinding mechanisms 310 are connected, the eccentric parts 3111 are respectively connected to the positions near the two ends of the grinding bolster component 400.

[0098] During grinding, two drive mechanisms 320 drive two rotating parts 311 to rotate synchronously. The two rotating parts 311 exert synchronous force on the grinding bolster 400 connected to them through the eccentric part 3111. Under the force of the two rotating parts 311, the grinding bolster 400 connected to them is driven to perform circumferential translation. Since the grinding bolster 400 is connected to the sanding belt frame and pressed on the sanding belt 240, the sanding belt frame and the sanding belt 240 are also driven to perform circumferential translation synchronously.

[0099] By grinding the board material using the aforementioned circular translation method, the vertical lines can be moved and ground in a circular motion, thereby completely removing the vertical lines on the board material and making the surface finish of the board material better meet the user's requirements.

[0100] In some embodiments of this application, the grinding pillow component 400 is located below and between the two sanding belt rollers 220, and is pressed onto the top surface of the sanding belt 240, forming a V-shaped structure on the line connecting the grinding pillow component 400 and the two sanding belt rollers 220.

[0101] Two sanding belt rollers 220 are arranged above, and the grinding bolster component 400 is arranged below the two sanding belt rollers 220 at the middle position. When it presses on the sanding belt 240, it will give the sanding belt 240 a downward clamping force. Meanwhile, the two sanding belt rollers 220, which are located above the grinding bolster component 400, will give the sanding belt 240 an upward lifting force. Under the opposite forces of the grinding bolster component 400 and the sanding belt rollers 220 on the sanding belt 240, the sanding belt 240 and the grinding bolster component 400 can fit more tightly, ensuring that the two will not have relative displacement when the sanding belt 240 drives the grinding bolster component 400 to move.

[0102] In some embodiments of this application, the belt abrasive drive mechanism 230 includes:

[0103] The first drive device 231 is mounted on the sanding belt frame 210 and is connected to one of the sanding belt rollers 220 in a transmission manner.

[0104] The second drive unit 232 is mounted on the sanding belt frame 210 and is connected to another sanding belt roller 220 in a transmission connection.

[0105] The first drive device 231 drives the sanding belt roller 220 connected thereto to perform a winding / unwinding motion, and the second drive device 232 drives the sanding belt roller 220 connected thereto to perform an unwinding / winding motion.

[0106] Specifically, the first drive device 231 includes a first drive motor 321 and a first reducer connected to the first drive motor 321, wherein the first reducer is connected to one of the sanding belt rollers 220 in a transmission connection.

[0107] The second drive unit 232 includes a second drive motor 321 and a second reducer, the second reducer being connected to another sanding belt roller 220.

[0108] The first drive motor 321 drives the first reducer to rotate, which in turn drives one of the sanding belt rollers 220 to rotate for unwinding. The second drive motor 321 drives the second reducer to rotate the other sanding belt roller 220 for winding.

[0109] When the sanding belt 240 on the sanding belt roller 220 connected to the first drive motor 321 has a remaining set length, the first drive motor 321 and the second drive motor 321 can be controlled to rotate in opposite directions, driving the sanding belt roller 220 connected to the second drive motor 321 to perform an unwinding motion and the sanding belt roller 220 connected to the first drive motor 321 to perform a winding motion, so as to realize the repeated use of the sanding belt 240 until the sanding belt 240 is damaged and then replaced, further extending the service life of the sanding belt 240.

[0110] In some embodiments of this application, the sanding belt frame 210 includes:

[0111] Two sub-frames 211 are symmetrically arranged at both ends of the sanding belt roller 220 and rotatably connected to the sanding belt roller 220. The two sub-frames 211 are respectively connected to both ends of the grinding pillow component 400.

[0112] The first drive device 231 and the second drive device 232 are mounted on one of the sub-frames 211.

[0113] Each sub-frame 211 includes:

[0114] The main frame 2111 is arranged vertically and is used to assemble two sanding belt rollers 220. Each sanding belt roller 220 is rotatably connected to the two main frame bodies 2111 at both ends during connection.

[0115] And the bending frame 2112, which is connected to the main frame 2111 and the grinding pillow component 400.

[0116] The main frame 2111 includes a main body and two support arms. The two support arms are symmetrically arranged on the main body, and a clearance space is formed between the two support arms.

[0117] In some embodiments of this application, the grinding machine also includes a belt tensioning device. During the grinding process, the belt 240 located between the grinding bolster component 400 and the belt roller 220 may become loose. In order to avoid the belt 240 becoming loose and affecting the grinding effect, a tensioning mechanism is provided at the position of the belt 240 between the grinding bolster component 400 and the belt roller 220 to press the belt 240 and achieve tensioning of the belt 240.

[0118] A tensioning section is formed on the abrasive belt 240 located between the grinding bolster component 400 and the abrasive belt roller 220. Two tensioning sections are formed on the abrasive belt 240 between the two abrasive belt rollers 220 and the grinding bolster component 400, and the two tensioning sections are arranged opposite to each other.

[0119] The institutions that tighten monetary policy include:

[0120] The tensioning drive component 710 is assembled onto the sanding belt frame 210 and includes a moving part 711.

[0121] The tensioning drive component 710 is a tensioning drive cylinder, which includes a cylinder seat, a fixed plate on the sanding belt frame 210, an insertion hole on the fixed plate, a shaft hole on the cylinder seat, and a connecting shaft 740 with one end interference-fitted into the insertion hole and the other end interference-fitted into the cylinder seat to achieve support and fixation of the cylinder seat.

[0122] The movable part 711 is the cylinder rod of the tension drive cylinder, which can perform telescopic movement.

[0123] The connecting unit is rotatably connected to the moving part 711;

[0124] The tension roller assembly 720, which is eccentric, is connected to the connecting unit;

[0125] When the tensioning drive 710 moving part 711 is activated, it drives the connecting unit to rotate. The connecting unit drives the tensioning roller group 720 connected to it to rotate and change its position, pressing the sanding belt 240 to move in the direction of the symmetrical line close to the middle position of the two sanding belt rollers 220 to tension the sanding belt 240.

[0126] When the cylinder rod of the tensioning drive cylinder extends or retracts, it drives the connecting unit connected to it to rotate, which in turn drives the eccentric tensioning roller group 720 to rotate. The tensioning roller group 720 is eccentric, and when it rotates, it changes the contact position with the sanding belt 240. When the eccentric section of the tensioning roller group 720 contacts the sanding belt 240, it will squeeze the sanding belt 240 and make it move towards the middle position of the two sanding belt rollers 220, that is, towards the direction of the symmetrical line of the two sanding belt rollers 220, so as to tighten the sanding belt 240.

[0127] The movable part 711 is connected to the connecting unit via a spherical bearing 750.

[0128] Each tensioning section is equipped with a tensioning mechanism, and the two tensioning mechanisms are positioned opposite each other.

[0129] The tensioning roller assembly 720 includes: a tensioning outer roller 721;

[0130] The inner tensioning roller 722, which is eccentric, is arranged inside the outer tensioning roller 721 and is rotatably connected to the outer tensioning roller 721. The inner tensioning roller 722 and the outer tensioning roller 721 can be rotatably connected by bearings.

[0131] When the inner tensioning roller 722 rotates, it can drive the outer tensioning roller 721 connected to it to rotate.

[0132] The tensioning inner roller 722 extends from the tensioning outer roller 721 at both ends. After extending, one end passes through the sub-frame 211 corresponding to the position of the connecting unit and connects to the connecting unit, while the other end is directly rotatably connected to another sub-frame 211.

[0133] The connection unit includes:

[0134] The connector 730 has a first connecting portion 532 and a second connecting portion 532;

[0135] The connecting shaft 740 is connected to the rotating connector 730 and the first connecting part 532;

[0136] The tensioning inner roller 722 is connected to the second connecting part 532.

[0137] The first connecting part 532 is a first connecting hole formed on the connector 730. The connecting shaft 740 is inserted into the first connecting hole to be fixedly connected with the connector 730. The other end of the connecting shaft 740 is fixedly connected to the rotating connector 730.

[0138] The second connecting part 532 is a second connecting hole for inserting the tensioning inner roller 722.

[0139] The rack 100 includes a first frame 110, a second frame 120, and a third frame 130.

[0140] The second frame 120 is slidably connected to the first frame 110, and the third frame 130 is equipped with the eccentric grinding mechanism 310 on its top.

[0141] The third frame 130 is the third crossbeam, with both ends located within the clearance space formed by the two sub-frames 211. The main body of the sub-frame 211 is located below the third frame 130, and it is connected to the grinding wheel component 400 by a bent frame 2112 that bends from the vertical to the horizontal direction.

[0142] The second frame 120 includes a second support plate 121 and a second support column 122 disposed on the second support plate 121.

[0143] The second support column 122 is symmetrically arranged at both ends of the third frame 130, which is located above the second support plate 121.

[0144] The above-described connection arrangement of the first frame 110 with the belt abrasive 210, the second frame 120 and the eccentric grinding mechanism 310 above it can achieve a compact arrangement between the belt abrasive 210 and the frame 100, reducing the space occupied and the overall volume of the grinding machine.

[0145] In some embodiments of this application, the grinding machine further includes a height adjustment mechanism 140, disposed between the third frame 130 and the second frame 120, for adjusting the height of the third frame 130.

[0146] When the thickness of the input plate changes, the height of the eccentric grinding mechanism 310 and the sanding belt unit 200 on the third frame 130 also needs to be adjusted. The height adjustment mechanism 140 arranged between the third frame 130 and the second frame 120 can adjust the height of the sanding belt unit 200 and the eccentric grinding mechanism 310 so that they can be adapted to different plate thicknesses.

[0151] When set up, the height adjustment power unit 141 includes a height adjustment motor and a height adjustment reducer connected to the height adjustment motor, and the output end of the height adjustment reducer is connected to the adjustment screw 142.

[0152] To achieve uniform height adjustment of the third frame 130 and the grinding unit 300 and sanding belt unit 200 above it, two height adjustment mechanisms 140 are provided, symmetrically arranged at both ends of the third frame 130.

[0153] During adjustment, the two height adjustment power components 141 operate simultaneously, driving the adjustment screw 142 connected to them to rotate, which in turn drives the adjustment nut 143 connected to it to move the third frame 130, the sanding belt unit 200, and the grinding unit 300 in a vertical linear motion, thereby achieving overall height adjustment.

[0154] The sliding guide assembly 144 includes a slider / slide rail disposed at the end of the third frame 130 and a slide rail / slider disposed on the second support column 122, and the height adjustment is achieved through the sliding cooperation of the slide rail and the slider.

[0155] In some embodiments of this application, the rotation axes of the two rotating components 311 are parallel to each other, and the axes of the eccentric parts 3111 are parallel to each other and have the same eccentricity. During grinding, the two rotate at the same speed, in the same direction and with the same phase. With the above arrangement, the two eccentric grinding mechanisms 310 can move synchronously to drive the grinding pillow component 400 and the sanding belt unit 200 to perform circumferential translation for circumferential grinding.

[0156] In some embodiments of this application, the rotating component 311 is a rotating shaft 540, which includes:

[0157] Rotating main body 3112;

[0158] The limiting part 3113 is connected to the rotating main body part 3112 and the eccentric part 3111;

[0159] The axis of the rotating main body 3112 is parallel to the axis of the eccentric part 3111 and has a certain distance between them.

[0160] The rotating main body 3112 is the rotating main body segment of the rotating shaft 540, the limiting part 3113 is the limiting segment, and the eccentric part 3111 is the eccentric segment. The rotating main body segment, the limiting segment and the eccentric segment are connected in sequence.

[0161] To support the rotating main body 3112, a sleeve is provided on the outside of the rotating main body 3112. The rotating main body 3112 and the sleeve are rotatably connected, and the sleeve is fixed on the third frame 130.

[0162] In some embodiments of this application, the grinding machine includes:

[0163] The connection component includes:

[0164] The first connector 330 is sleeved on the outside of the eccentric part 3111 and connected to the eccentric part 3111.

[0165] The second connector 340 is fixedly connected to the first connector 330;

[0166] The sanding belt frame 210 is partially disposed between the second connector 340 and the grinding pillow component 400;

[0167] An elastic element is arranged between the sanding belt frame 210 and the second connecting member 340;

[0168] The locking component passes through the second connector 340, the elastic element and the sanding belt frame 210 and is locked and fixed inside the grinding pillow component 400.

[0169] The first connecting member 330 is a first connecting sleeve, which is sleeved on the outside of the eccentric part 3111 and is rotatably connected to the eccentric part 3111 through a bearing or directly fixedly connected to the eccentric part 3111.

[0170] The second connector 340 is a second connecting plate, which is attached to the bottom of the first connector 330 and fixedly connected to the first connector 330.

[0171] The bent frame 2112 of the sanding belt frame 210 extends to the position between the second connector 340 and the grinding pillow component 400.

[0172] The elastic element is an elastic rubber pad.

[0173] An adjustment elongated hole is provided on the second connector 340.

[0174] During connection, the locking component passes through the adjustment elongated hole, the elastic element, and the bending frame 2112 and is locked and fixed inside the grinding pillow component 400 to achieve fixation.

[0175] The grinding pillow base is 410, and is elongated. The length of the grinding pillow component is 1000-1060cm, and the width is 170-190cm. The large overall area increases the grinding area and enhances the grinding effect.

[0176] When setting up, the grinding and vibration base can be configured as a long rectangular parallelepiped structure with its bottom surface set as a plane.

[0177] By setting the entire grinding pillow base 410 into a long strip structure, the contact area between it and the abrasive belt 240 can be increased, thereby increasing the contact area between the abrasive belt 240 and the plate, realizing large-area rapid grinding and improving grinding efficiency.

[0178] The grinding pillow base 410 is a rigid component. During molding, the grinding pillow base 410 can be made of aluminum profile to reduce the weight of the entire grinding pillow base 410.

[0179] The grinding pillow component 400 includes an elastic buffer 420, which is arranged below the grinding pillow base 410 and extends along the length of the grinding pillow base 410.

[0180] When in use, the grinding pillow component 400 mainly drives the sanding belt 240 to move and perform grinding operations on the plate through sanding belts 240 of different fineness.

[0181] Since the grinding pillow base 410 is a rigid component, if it directly drives the sanding belt 240 to wear the plate, the grinding pillow base 410 and the plate will have a hard contact fit, which may damage the plate being ground.

[0182] To avoid the above problems, an elastic buffer 420 is arranged below the grinding pad base 410. The elastic buffer 420 is elastic and can play a certain buffering role. This can avoid the hard contact between the grinding pad base 410 and the plate, and effectively avoid the problem of damage to the plate when grinding.

[0183] The elastic buffer 420 can change with the shape of the sanding belt 240, and can always maintain close contact with the sanding belt 240. It can effectively increase the support effect of the sanding belt 240, so that the sanding belt 240 fits the surface of the workpiece more closely when it comes into contact with the plate or other materials. It can adaptively change its shape according to the shape of the surface of the workpiece, improve the sanding effect, and increase the performance.

[0184] Wear-resistant component 430 is arranged along the length of the grinding pillow base 410 and below the elastic buffer component 420. After wrapping the elastic buffer component 420, its two ends are bent upward and fixedly connected to the grinding pillow base 410.

[0185] The wear-resistant part 430 is made of graphite cloth, which is used to reduce wear between the wear-resistant part and the abrasive belt 240.

[0186] When the graphite cloth is installed, it is attached to the bottom position of the elastic buffer 420, and its two ends along the width direction extend upward along the two sides of the elastic buffer 420 to the two sides of the grinding pillow base 410 and connect with the grinding pillow base 410.

[0187] The elastic buffer 420 can be wrapped and pressed between the graphite cloth and the grinding pillow base 410 to fix the elastic buffer 420.

[0188] An adsorption channel is formed between the wear-resistant part 430, the elastic buffer part 420 and the grinding pillow substrate 410.

[0189] In this embodiment, the grinding pillow component 400 can be used in conjunction with the negative pressure fan 800. By arranging the negative pressure fan 800 and the adsorption channel in a corresponding manner, a negative pressure is generated inside the adsorption channel when the negative pressure fan is working. Through the negative pressure, the abrasive belt 240 wrapped around the grinding pillow base 410 is firmly adsorbed onto the grinding pillow base 410, making it adaptable to the grinding machine structure in which the grinding pillow component 400 moves and grinds with the abrasive belt 240. Moreover, during the grinding process, the negative pressure adsorption prevents the abrasive belt 240 from moving and changing position relative to the grinding pillow component 400, thus ensuring the grinding effect.

[0190] In some embodiments of this application, the grinding pillow component 400 includes:

[0191] Two clamping parts 440 are provided, which are used to clamp the two ends of the wear-resistant part 430 respectively;

[0192] The locking member 450 passes through the pressing member 440 and is locked and fixed inside the grinding pillow base 410.

[0193] The pressing component 440 is a pressing plate that extends along the length of the wear-resistant substrate to uniformly press and fix the end of the wear-resistant component 430, thereby ensuring the grinding effect.

[0194] The locking element 450 is a locking screw, which passes through the pressing element 440 and is locked and fixed in the wear-resistant substrate to fix the pressing element 440.

[0195] In some embodiments of this application, the grinding wheel substrate 410 includes:

[0196] The first grinding wheel base 411 consists of two symmetrically arranged components.

[0197] The second grinding wheel base 412 is located below the first grinding wheel base 411, and its two ends are respectively connected and fixed to the two first grinding wheel bases 411;

[0198] Reinforcing connectors 730 are connected between two first grinding pad bases 411, and multiple connectors are provided and arranged along the length of the first grinding pad bases 411.

[0199] The first grinding pillow base 411 is the first grinding pillow beam, and two of them are set up symmetrically, with a gap between the two first grinding pillow beams.

[0200] The second grinding pillow base 412 is a second grinding pillow plate, which is rectangular and is attached to the bottom surface of the two first grinding pillow bases 411 and locked and fixed to the two first grinding pillow bases 411.

[0201] The reinforcing connector 730 is a reinforcing connecting plate, which is arranged above the second grinding pad plate, perpendicular to the two first grinding pad bases 411 and connected to the two first grinding pad bases 411 at both ends, so as to enhance the strength of the entire grinding pad base 410.

[0202] In some embodiments of this application, a first flow hole 413 is formed on the grinding wheel substrate 410;

[0203] A second flow hole is formed on the elastic buffer member 420;

[0204] A third flow hole is formed on the wear-resistant part 430;

[0205] The first flow hole 413, the second flow hole and the third flow hole are interconnected to form the adsorption channel.

[0206] In a specific configuration, the first flow hole 413 is set on the second grinding pad base 412, and multiple rows are set, with each row arranged along the length direction of the grinding pad base 410.

[0207] The second flow holes are also arranged in multiple rows, each corresponding to a different position on the second grinding wheel base 412, to ensure mutual communication.

[0208] The wear-resistant part 430 is made of graphite cloth, and the gaps between the holes formed by its weaving constitute the third flow hole.

[0209] In some embodiments of this application, in order to enable the second frame 120 to automatically slide out relative to the first frame 110 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.

[0210] The transmission device 520 is arranged on the second frame 120 and the first frame 110 and is connected to the sliding drive device 510. When the sliding drive device 510 is activated, the transmission device 520 drives the second frame 120 to slide out relative to the first frame 110.

[0211] The sliding drive device 510 provides sliding power. The sliding drive device 510 may be a motor and a reducer. The motor and the reducer are connected, and the reducer has an output end.

[0212] 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 together.

[0213] During setup, the transmission rack is mounted on the second frame 120 and arranged along the length of the second frame 120.

[0214] 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 frame 120 connected to the transmission rack to slide relative to the first frame 110.

[0215] By setting up a sliding drive device 510 in conjunction with a transmission device 520, the second frame 120 can be automatically slid out relative to the first frame 110, achieving automatic sliding without the need for manual operation, thus saving manpower.

[0216] In some embodiments of this application, a sliding rail 123 is provided on at least one side of the second frame 120, and a sliding roller 114 that cooperates with the sliding rail 123 is provided on the first frame 110.

[0217] In some embodiments of this application, the grinding mill further includes:

[0218] An anti-warping component is disposed on the first frame 110 and pressed onto the second frame 120, and is rotatably connected to the second frame 120.

[0219] As the second frame 120 is pulled outward relative to the first frame 110, the weight of the outer part of the second frame 120 will increase as the outward part of the second frame 120 is extended. In order to prevent the second frame 120 from tilting up due to the uneven weight at both ends during the pulling process, anti-warping components are arranged on the first frame 110. These components can be pressed onto the second frame 120 to prevent it from tilting up and ensure the normal sliding out of the second frame 120.

[0220] When the anti-warping component is installed, it is pressed onto the top surface of the second frame 120 and rolled between the second frame 120, so that the friction between it and the second frame 120 is rolling friction. In this way, when the second frame 120 slides out, it can both ensure the pressing and limiting of the second frame 120 and reduce the friction between it and the second frame 120, ensuring that the second frame 120 slides out smoothly.

[0221] In some embodiments of this application, the anti-warping component includes:

[0222] Anti-warping seat 530, fixed on the first frame 110, includes:

[0223] Main support part 531; and

[0224] The connecting part 532 is vertically connected to the main body support part 531;

[0225] The rolling pressing assembly is horizontally mounted on the connecting part 532 and extends toward the second frame 120.

[0226] In some embodiments of this application, the rolling pressing component includes:

[0227] Shaft 540 is inserted into the connecting part 532;

[0228] A rolling bearing 550 is assembled to the end of the shaft 540 that extends from the connecting part 532 and is used to press onto the second frame 120.

[0229] The first frame 110 includes a first end 115 and a second end 116 disposed opposite to the first end 115.

[0230] The grinding machine also includes a first limiting unit, which includes a first limiting member 117 disposed at the first end 115 of the first frame 110 and a first limiting cooperating member 124 disposed on the second frame 120 and cooperating with the first limiting member 117.

[0231] When the second frame 120 is slid out along the direction from the second end 116 to the first end 115, the distance it slides out is limited by the cooperation of the first limiting member 117 on the first frame 110 and the first limiting cooperating member 124 on the second frame 120, so as to prevent the second frame 120 from coming out of the first frame 110.

[0232] The first limiting component 117 is the first limiting block, and the first limiting mating component 124 is the second limiting mating block.

[0233] The first limiting unit includes a second limiting member 118 disposed at the second end 116 of the first frame 110 and a second limiting cooperating member 125 disposed on the second frame 120 and cooperating with the second limiting member 118.

[0234] When the second frame 120 slides and resets along the direction from the first end 115 to the second end 116, the second limiting member 118 on the first frame 110 and the second limiting cooperating member 125 on the second frame 120 cooperate to limit the sliding push distance, ensuring that the second frame 120 resets quickly.

[0235] 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 115 of the first frame 110 and a first limiting sensing element disposed on the second frame 120 and cooperating with the first limiting element.

[0236] 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.

[0237] The software limit is achieved by the first limit sensor and the first limit element to prevent the second frame 120 from falling out of the first frame 110 when it moves along the direction from the first end 115 to the second end 116.

[0238] The second limiting unit includes a second limiting element disposed at the second end 116 of the first frame 110 and a second limiting sensor disposed on the second frame 120 and cooperating with the second limiting element.

[0239] 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.

[0240] The second limit sensor and the second limit element work together to achieve software-controlled movement of the second frame 120 along the direction from the second end 116 to the first end 115.

[0241] The first limiting unit can mechanically limit the movement of the second frame 120, and the second limiting unit can software limit the movement of the second frame 120. The mechanical and software limiting work together to ensure the movement of the second frame 120 on the first frame 110.

[0242] In some embodiments of this application, the first frame 110 includes:

[0243] There are two longitudinal beams, 111 in total, arranged at a certain interval.

[0244] Two transverse beams 112 are provided and interconnected with the two longitudinal beams 111, forming a first clearance section between the longitudinal beams 111 and the transverse beams 112.

[0245] One of the transverse beams 112 is connected at both ends to one end of each of the two longitudinal beams 111, and the other transverse beam 112 is connected at both ends to the other ends of the two longitudinal beams 111.

[0246] Two extension plates 113 are provided and are respectively connected to two transverse beams 112. The sliding rollers 114 are provided on the two extension plates 113. The anti-warping component and the sliding drive device 510 are provided on one of the extension plates 113.

[0247] The first clearance part is the first clearance hole, and the first clearance hole is a square hole.

[0248] The second frame 120 is provided with a second clearance part, which is connected to the first clearance part. The second clearance part is a second clearance hole, which is corresponding to and connected to the first clearance hole.

[0249] The first and second clearance holes can be used to avoid the sanding belt unit 200 and the grinding unit 300.

[0250] In some embodiments of this application, the grinding mill has a first operating mode and a second operating mode:

[0251] When it is in the first working mode, the two eccentric grinding mechanisms 310 drive the sanding belt unit 200 to perform circumferential translational grinding. When the sanding belt 240 is grinding, the first driving device 231 and the second driving device 232 continuously maintain the winding and unwinding action. The displacement of the sanding belt 240 relative to the grinding pillow component 400 per minute is less than the width of one grinding pillow component 400.

[0252] Under the combined action of the first drive device 231 and the second drive device 232, the sanding belt 240 moves along the width direction of the grinding bolster component 400, so that the new sanding belt 240 partially replaces the sanding belt 240 located at the bottom part of the grinding bolster component 400.

[0253] When the grinding machine grinds the board, the first drive device 231 and the second drive device 232 can be controlled to keep moving continuously, so as to move the sanding belt 240 to replace the part of the sanding belt 240 located below the grinding bolster component 400 with a small displacement per minute, which is less than the width of one grinding bolster component 400, so as to achieve the purpose of replacing the old sanding belt 240 with the new one.

[0254] In the second working mode, the two eccentric grinding mechanisms 310 drive the sanding belt unit 200 to perform circumferential translational grinding. After a preset time interval, the first driving device 231 and the second driving device 232 perform winding and unwinding actions to make the sanding belt 240 move a preset length relative to the grinding pillow component 400. The preset length is greater than or equal to the width of one grinding pillow component 400.

[0255] During the grinding process of the grinding machine on the board, the abrasive belt 240 can also be replaced at a set time interval according to the wear cycle of the abrasive belt 240 determined by the experiment. That is, the first drive device 231 and the second drive device 232 are controlled to move once every set time interval, moving a preset length greater than the width of one grinding pad component 400, so as to replace the worn abrasive belt 240 part at the bottom of the grinding pad component 400, so as to ensure the normal operation of the grinding operation.

[0256] After the sanding belt 240 is moved and ground by the grinding pillow component 400, dust from the grinding plate will adhere to its top. If the sanding belt 240 is directly wound onto the sanding roller 220 by the sanding belt 240 drive unit, it will not be able to be used normally in the later stages because of the sand and dust adhering to the sanding belt 240.

[0257] To avoid the aforementioned problems, in some embodiments of this application, a dust blowing mechanism is provided at the sanding belt 240 section between the grinding pillow component 400 and the sanding belt roller 220, arranged along the width direction of the sanding belt 240.

[0258] The dust blowing mechanism includes a dust blowing cylinder 610, which has a dust blowing cylinder rod. A dust blowing pipe 620 arranged along the width direction of the sanding belt 240 is mounted on the sanding belt frame 210. The dust blowing pipe 620 is provided with a plurality of dust blowing holes facing the sanding belt 240. The dust blowing pipe 620 is also provided with an air inlet connected to an air intake device to continuously blow air into the pipe.

[0259] The dust-blowing cylinder rod is telescopically connected to the dust-blowing pipe 620, and blows the dust off the sanding belt 240 through multiple dust-blowing holes on the blow-out pipe.

[0260] In the setup, the dust blowing mechanism is provided on both sanding belt sections between the grinding pillow component 400 and the two sanding belt rollers 220 to meet the dust blowing requirements of the sanding belt 240 when it is repeatedly wound up and unwound.

[0261] The method of using the grinding machine in this embodiment includes the following steps:

[0262] Based on the thickness of the conveyed plate, the height adjustment mechanism 140 is controlled to adjust the distance between the sanding belt 240 in the sanding belt unit 200 and the conveying bed.

[0263] When grinding plates of different thicknesses, the distance between the abrasive belt unit 200 and the plate needs to be adjusted. The height of the grinding unit 300 and the abrasive belt unit 200 connected to the grinding unit 300 can be adjusted by the height adjustment mechanism 140 so that it can be adapted to the thickness of the grinding plate.

[0264] The two eccentric grinding mechanisms 310 are activated, which drive the grinding pillow component 400 and the sanding belt 240 to perform circumferential translation to grind the plate.

[0265] The plate is conveyed to the grinding unit 300 via a conveyor bed. When it is conveyed to the grinding unit 300, the grinding pillow component 400 and the sanding belt 240 are driven to perform circumferential translational grinding by the action of two eccentric grinding mechanisms 310.

[0266] During the plate grinding operation, the first drive device 231 rotates along the first direction, the second drive device 232 rotates along the second direction, and the grinding machine operates in the first working mode or the second working mode.

[0267] During grinding, the grinder can be selected to enter either the first working mode or the second working mode.

[0268] When the length of the sanding belt 240 on the unwound sanding belt roller 220 is detected to be less than the set length, the first drive device 231 is controlled to rotate along the second direction, the second drive device 232 rotates along the first direction, and the eccentric grinding mechanism 310 maintains the grinding operation state, wherein the first direction and the second direction are opposite.

[0269] When the sanding belt 240 on the unwinding sanding belt roller 220 is less than the set length, it means that the sandpaper on the unwinding sanding belt roller 220 is about to run out. In order to prevent the sanding belt 240 from falling off and affecting the normal grinding operation, the first drive device 231 and the second drive device 232 can be controlled to rotate in opposite directions so that the unwinding sanding belt roller 220 can be wound up and the wound sanding belt roller 220 can perform unwinding motion.

[0270] The motion control of the first drive device 231 and the second drive device 232 can be achieved manually or through the controller of the grinding machine.

[0271] The remaining length of the 240mm sander belt can be determined visually or by using existing detection sensors.

[0272] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
