Description

Technical Field

[0001] The invention relates to the technical field of tile processing and conveying, in particular to a tile feeding device for a polishing machine. Background Art

[0002] Glazed tiles are a new type of tiles that are made by polishing the surface of ordinary glazed tiles. Compared with ordinary tiles, their surface is smoother, harder and more wear-resistant. Therefore, during the processing of glazed tiles, a conveying device is required to transport the tiles to the polishing machine.

[0003] The patent publication number of the existing patent application is: CN116873507A, and the publication date is October 13, 2023. The name of the patent is "A kind of automatic brick feeding device for tiles". The patent includes a first support frame, a brick feeding mechanism and a fixing mechanism. The upper surface of the first support frame is movably connected to the second support frame, and a fixed plate is symmetrically fixed on one side of the second support frame. The automatic brick feeding device for tiles, through the setting of the brick feeding mechanism and the fixing mechanism, sets the parameters of the stepping motor through the control panel to adjust the speed of the control wheel to control the distance between the tiles pushed onto the conveyor belt for transmission. Therefore, with the cooperation of the main controller, the control panel, the fixing mechanism, the brick feeding mechanism, the first electric telescopic rod, the first infrared sensor and the block, it is possible to easily adjust the distance between the controlled tiles to avoid collision and damage between the tiles, and avoid the situation where the tiles are piled up on the conveyor belt. The automated brick feeding method improves the brick feeding efficiency.

[0004] The above application has shortcomings. In actual processing, the tiles need to be neatly placed in the polishing machine for polishing. Generally, a simple conveyor belt structure is used to transport the tiles. Due to the incomplete consistency of the shape and size of the tiles, as well as factors such as vibration and offset during transportation, the tiles often collide and dislocate during transportation, thereby affecting the polishing effect and production efficiency. At the same time, when the tiles move at high speed on the conveyor belt, if they encounter obstacles or edges on both sides of the conveyor belt, collision and friction are likely to occur, causing damage to the edges of the tiles or scratches on the surface, further reducing the product qualification rate and production efficiency. Summary of the invention

[0005] The object of the present invention is to provide a brick feeding device for a polishing machine to solve the deficiencies in the above-mentioned prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

A pair of abutment rods that abut against the anti-collision and deviation correction mechanisms are fixedly connected on both sides of the inner wall of the conveyor platform. When the conveyor belt conveys tiles, it drives the transmission belt to run synchronously. The abutment rods force the anti-collision and deviation correction mechanisms abutting against it to reserve a tile insertion space. When the anti-collision and deviation correction mechanism is removed from the abutment rods, the anti-collision and deviation correction mechanism squeezes the edge of the tile and corrects the tile conveying position.

[0008] Preferably, driving shafts are installed at both ends of the conveyor belt, and transmission shafts are installed at both ends of the transmission belt, and the driving shafts and the transmission shafts are connected via belt transmission.

[0009] Preferably, a pair of transmission rollers are installed in the conveying platform, the top surface of the conveyor belt is in contact with the bottom of the transmission rollers, and a plurality of conveying rollers are installed between the pair of transmission rollers.

[0010] Preferably, the anti-collision and deviation-correcting mechanism includes a hollow partition fixed to the outside of the conveyor belt, a pressure frame is elastically installed in the hollow partition, pads are fixedly connected on both sides of the inner wall of the conveyor platform, the abutment rod is fixed to the top surface of the pad, pressure plates are elastically installed on both sides of the pressure frame outside the hollow partition, and a tension spring is installed between the pressure plate and the pressure frame.

[0011] Preferably, the bottom of the pressure plate is slidably connected to a push plate, the back of the push plate is fixedly connected to a push rod, the end of the push rod is vertically fixedly connected to a telescopic rod, and the top surface of the pad is provided with a guide groove for inserting the telescopic rod.

[0012] Preferably, the groove body between the two driving rollers in the guide groove is close to the conveyor belt, and when the telescopic rod moves to this section of the groove body, the push plate moves toward the tile direction.

[0013] Preferably, both ends of the transmission roller are fixedly connected to limit rings, the spacing between the two limit rings is adapted to the width of the conveyor belt, and a cleaning brush sleeve is embedded outside the transmission roller, and the bristles on the surface of the cleaning brush sleeve respectively contact the outside of the conveyor belt and the back of the tile.

[0014] Preferably, the top of the abutment rod is fixedly connected to an abutment rack, the bottom of the abutment frame is abutted against the abutment rack, an airbag is installed inside the hollow partition, the bottom of the airbag abuts against the top of the abutment frame, and the top of the airbag is installed with an air blowing hose connected to the airbag in the adjacent hollow partition, and the air port of the air blowing hose faces the conveyor belt.

[0015] Preferably, a connecting seat is slidably installed on the top of the pressure frame, a connecting rod is hinged on the connecting seat, a pulling frame is installed on the top of the pressure plate in the hollow partition, a through groove is vertically opened on the pulling frame for the end of the connecting rod to be inserted, a connecting shaft is fixedly connected to the central hinge point of the connecting rod, one end of the connecting shaft passes through the hollow partition and is fixedly connected to a cross bar, a connecting spring is provided on the outer sleeve of the connecting shaft, and both ends of the connecting spring are respectively against the cross bar and the hollow partition.

[0016] Preferably, a check rack is fixedly connected to one side of the inner wall of the through groove, and the end of the connecting rod is clamped with the check rack.

[0017] In the above technical solution, by setting a conveyor belt as the main load-bearing and conveying component for tiles, its operation not only drives the advancement of tiles, but also drives the synchronous movement of the transmission belt, and transmits power to the anti-collision and correction mechanism, so that each anti-collision and correction mechanism can move to the corresponding position in turn when the tiles are placed on the conveyor belt, and automatically adjust its movement speed according to the speed and position changes of the conveyor belt. The anti-collision and correction mechanism can not only separate adjacent tiles to avoid collision between adjacent tiles, but also, in the initial stage of tile transportation, utilize the abutment cooperation between the anti-collision and correction mechanism and the abutment rod to ensure that sufficient insertion space is reserved under the anti-collision and correction mechanism to ensure that the corners of the tiles can enter the insertion space. As the tiles continue to be conveyed, the anti-collision and correction mechanism gradually moves away from the abutment rod. At this time, when the adjacent anti-collision and correction mechanism has initially defined the position of the tiles, the anti-collision and correction mechanism moved away from the abutment rod will push and reset to press the edge of the tiles. This action can effectively correct and avoid the deviation of the tiles during transportation. Since the anti-collision and correction mechanisms are evenly spaced on the outside of the transmission belt, they can continuously and stably correct the tiles to ensure that the tiles maintain the correct position and posture during the entire transportation process. This continuous and precise control improves the success rate and efficiency of the polishing operation, and reduces rework and waste caused by improper positioning or damage of tiles.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] See also Figure 1-9 A polishing machine brick feeding device provided by an embodiment of the present invention includes a conveying platform 1 and a conveyor belt 2 installed in the conveying platform 1, and also includes a pair of transmission belts 3, which are respectively installed on both sides of the inner wall of the conveying platform 1, and the transmission belt 3 is connected to the conveyor belt 2 for transmission, and a plurality of anti-collision and deviation correction mechanisms 4 are distributed at equal intervals on the outside of the transmission belt 3. A pair of abutment rods 101 that abut against the anti-collision and deviation correction mechanism 4 are fixedly connected on both sides of the inner wall of the conveying platform 1. When the conveyor belt 2 conveys tiles, it drives the transmission belt 3 to run synchronously. The abutment rod 101 forces the anti-collision and deviation correction mechanism 4 abutting against it to reserve a tile insertion space. When the anti-collision and deviation correction mechanism 4 is removed from the abutment rod 101, the anti-collision and deviation correction mechanism 4 squeezes the edge of the tile and corrects the tile conveying position.

[0034] Specifically, the main supporting member of the device is a conveyor platform 1, on which a conveyor belt 2 driven by a motor is laid. The conveyor belt 2 runs continuously under the drive of the motor and is responsible for conveying the tiles to be processed from the feed end to the feed end located at the entrance of the polishing machine, and then allowing the tiles to enter the processing area of ​​the polishing machine. In order to enhance the stability and accuracy of the tile transportation, a pair of parallel transmission belts 3 are installed on both sides of the inner wall of the conveyor platform 1. These transmission belts 3 are linked with the conveyor belt 2 through a transmission structure, that is, when the conveyor belt 2 starts to run, the transmission belt 3 will also start synchronously to form lateral protection and guidance for the tiles. Several anti-collision and deviation correction mechanisms 4 arranged at equal intervals on the outside of the transmission belt 3 are used to separate adjacent tiles to avoid friction and collision between the corners of the tiles. Each anti-collision and deviation correction mechanism 4 also has a downward fixing structure so that it can squeeze the tiles when in contact to ensure their stability during transportation, and it is also convenient to achieve fine-tuning and correction of the position. Two pairs of abutment rods 101 are fixed on both sides of the inner wall of the conveyor platform 1, wherein the two coaxial abutment rods 101 are at the conveying The positions of the two conveyor belts 3 and the anti-collision and deviation correction mechanism 4 are respectively corresponding to the moving paths of the anti-collision and deviation correction mechanism 4. When the anti-collision and deviation correction mechanism 4 on both sides of the conveyor belts reaches the top of the abutment rod 101, the downward pressing structure in the anti-collision and deviation correction mechanism 4 is lifted upward by the abutment rod 101, and the placement space of the tiles is not occupied. At this time, the tiles are placed at the rear position of the anti-collision and deviation correction mechanism 4, and one side of the tiles is abutted against it. During the continuous operation of the conveyor belt 2, the anti-collision and deviation correction mechanism 4 on the two conveyor belts 3 is When leaving the abutment rod 101, the structure 4 is reset and squeezes two corners of the tile respectively, corrects the offset of the tile, and stabilizes two corners on one side of the tile to ensure that the tile is transported in the correct posture. Then the adjacent anti-collision and correction mechanism 4 at the rear moves to the abutment rod 101, and the downward pressing structure therein is first lifted and then reset to squeeze the two corners on the other side of the tile, so that the tile will not deviate too much during the transportation process, ensuring that it can accurately enter the processing area of ​​the polishing machine and the tile feeding device of the polishing machine.

[0035] Compared with the prior art, the embodiment of the present invention sets the conveyor belt 2 as the main load-bearing and conveying component of the tiles. Its operation not only drives the tiles forward, but also drives the synchronous movement of the transmission belt 3, and transmits power to the anti-collision and correction mechanism 4, so that each anti-collision and correction mechanism 4 can move to the corresponding position in turn when the tiles are placed on the conveyor belt 2, and automatically adjust its moving speed according to the speed and position changes of the conveyor belt 2. The anti-collision and correction mechanism 4 can not only separate adjacent tiles to avoid collision between adjacent tiles, but also in the initial stage of tile transportation, the anti-collision and correction mechanism 4 can be used to cooperate with the abutment rod 101 to ensure that sufficient insertion space is reserved under the anti-collision and correction mechanism 4 to ensure that the corners of the tiles can enter the insertion space. In the connecting space, as the tiles continue to be conveyed, the anti-collision and correcting mechanism 4 gradually moves away from the abutment rod 101. At this time, when the adjacent anti-collision and correcting mechanism 4 has preliminarily defined the position of the tiles, the anti-collision and correcting mechanism 4 moved away from the abutment rod 101 will push and reset to press the edge of the tiles. This action can effectively correct and avoid the deviation of the tiles during the transportation process. Since the anti-collision and correcting mechanisms 4 are evenly spaced on the outside of the transmission belt 3, they can continuously and stably correct the tiles to ensure that the tiles maintain the correct position and posture during the entire transportation process. This continuous and precise control improves the success rate and efficiency of the polishing operation, and reduces the rework and waste caused by improper positioning or damage of tiles.

[0036] In a further embodiment of the present invention, driving shafts 201 are installed at both ends of the conveyor belt 2, and transmission shafts 301 are installed at both ends of the transmission belt 3. The driving shaft 201 and the transmission shaft 301 are connected by a belt 202. Specifically, while the conveyor belt 2 is conveying tiles, it can also drive the transmission belts 3 on both sides of the conveyor belt 2 to run synchronously through the belt 202, so that the transmission belt 3 drives each anti-collision and correction mechanism 4 and the tiles to maintain the same moving speed, ensuring that the tiles will not be offset due to the movement of the anti-collision and correction mechanism 4 during transportation, and allowing the anti-collision and correction mechanism 4 to limit the tiles more stably.

[0037] In a further embodiment of the present invention, a pair of transmission rollers 5 are installed in the conveyor platform 1, the top surface of the conveyor belt 2 is in contact with the bottom of the transmission rollers 5, and a concave area is formed on the top surface of the conveyor belt 2 between the pair of transmission rollers 5. A plurality of conveyor rollers 6 are installed between the pair of transmission rollers 5, and the conveyor rollers 6 and the transmission rollers 5 are both in the concave area. Specifically, the transmission rollers 5 press the conveyor belt 2 to change the shape of the top surface of the conveyor belt 2, so that the tiles can be horizontally moved from the conveyor belt 2 to the conveyor rollers 6. Since the contact area between the conveyor rollers 6 and the tiles is greatly reduced compared to the contact area between the conveyor belt 2 and the tiles, the anti-collision and correction mechanisms 4 on the transmission belts 3 on both sides can more easily calibrate the position of the tiles. At the same time, the tiles on the conveyor rollers 6 will also be pushed forward by the anti-collision and correction mechanisms 4, so that the tiles can be corrected in the process of moving forward and centered before entering the entrance of the polishing machine. In the process of correction, the back of the tiles will not contact the conveyor belt 2, thereby reducing the wear on the conveyor belt 2 during the offset adjustment of the tiles and extending the service life of the conveyor belt 2.

[0038] In a further embodiment of the present invention, the anti-collision and deviation correction mechanism 4 includes a hollow partition 401 fixed to the outside of the conveyor belt 2, the hollow partition 401 is installed on the conveyor belt 2 by bolts or other fasteners, a pressure frame 402 is elastically installed in the hollow partition 401, a compression spring 413 is installed between the top of the pressure frame 402 and the top of the inner wall of the hollow partition 401, pads 102 are fixedly connected on both sides of the inner wall of the conveyor platform 1, the abutment rod 101 is fixed to the top surface of the pad 102, and it is located on the movable path of the pressure frame 402, and pressure plates 403 are elastically installed on both sides of the pressure frame 402 outside the hollow partition 401, a tension spring 404 is installed between the pressure plate 403 and the pressure frame 402, a plug-in protrusion is fixedly connected to one side of the pressure plate 403, and a plug-in protrusion matching the plug-in protrusion is vertically opened on the side of the pressure frame 402 The slide groove has the tension spring 404 located in it. Specifically, the pressure frame 402 and the abutment rod 101 are in abutment with each other. When the pressure frame 402 in the anti-collision and correction mechanism 4 does not abut the abutment rod 101, the pressure frame 402 presses down with the pressure plate 403 under the action of the compression spring 413. When the bottom of the pressure frame 402 abuts against the abutment rod 101 and moves forward, the pressure frame 402 lifts the pressure plate 403, thereby facilitating the corners of the tiles to enter under the pressure plate 403. When the pressure frame 402 is removed from the abutment rod 101, the pressure plates 403 on both sides firmly press the two adjacent tiles under the pulling of the pressure frame 402 and the action of the tension spring 404. The pressure plate 403 can gently press the tiles tightly through the cooperation of the compression spring 413 and the tension spring 404, thereby reducing the vibration caused by the pressure plate 403 pressing the tiles.

[0039] In a further embodiment of the present invention, a push plate 405 is slidably connected to the bottom of the pressure plate 403, a push rod 406 is fixedly connected to the back of the push plate 405, and a push plate is elastically connected to the other side of the push plate 405. A limit groove 302 for the push rod 406 to pass through is vertically opened on the transmission belt 3, and the end of the push rod 406 passes through the limit groove 302 and is vertically fixedly connected to a telescopic rod 407. A guide groove 103 for inserting the telescopic rod 407 is opened on the top surface of the pad 102. Specifically, as an intermediate component connecting the push plate 405 and the telescopic rod 407 One end of the push rod 406 is firmly fixed on the push plate 405, and the other end is connected to the top of the telescopic rod 407. The telescopic rod 407 can prevent the push rod 406 from bending during the lifting and lowering of the pressure plate 403. The moving trajectory of the telescopic rod 407 is changed by the guide groove 103, so that the push rod 406 pushes the push plate 405 toward the tile placement position at a suitable position. The push plates 405 in the anti-collision and deviation correction mechanisms 4 on both sides are pushed synchronously, so that the tiles can be adjusted to the central area of ​​the conveyor belt 2 when both sides are under force.

[0040] In a further embodiment of the present invention, the groove body between the two driving rollers 5 in the guide groove 103 is close to the conveyor belt 2. When the telescopic rod 407 moves to this section of the groove body, the push plate 405 moves toward the direction of the tile. Specifically, the guide groove 103 opened on the top surface of the pad 102 not only provides a stable moving path for the telescopic rod 407, but also realizes precise control of the position of the tile by adjusting its shape. In particular, the groove body part between the two driving rollers 5 is designed to be close to the conveyor belt 2. This design enables the push rod 406 to be pushed outward by changing the horizontal position of the telescopic rod 407 when the telescopic rod 407 moves to this section of the groove body. The push plate 405 is moved to complete the movement toward the tile on the conveying roller 6 between the two driving pressure rollers 5, and when the tile reaches above each conveying roller 6, the final position of the tile is adjusted by the cooperative push of the push plates 405 on both sides, so that the back of the tile will not contact the conveyor belt 2 during adjustment, and the friction on the back of the tile during the correction process is reduced, so that the push plate 405 can be pushed faster. When the tile moves to the feeding position, the corresponding push plate 405 will move back under the influence of the guide groove 103, and the abutment frame will also lift the pressure plate 403 after abutting against the abutment rod 101 at the feeding position, so as to facilitate the tile to enter the polishing machine.

[0041] In a further embodiment of the present invention, both ends of the transmission roller 5 are fixedly connected to limit rings 502, and the spacing between the two limit rings 502 is adapted to the width of the conveyor belt 2. A cleaning brush cover 501 is embedded outside the transmission roller 5, and the bristles on the surface of the cleaning brush cover 501 respectively contact the outside of the conveyor belt 2 and the back of the tile. Specifically, the spacing between the two limit rings 502 is adapted to the width of the conveyor belt 2. This design ensures that the transmission roller 5 can be tightly and evenly pressed against the conveyor belt 2 when rotating, and the conveyor belt 2 will not deviate and shake due to an excessively large gap, nor will the friction resistance be increased due to an excessively small gap to damage the conveyor belt 2. The brush sleeve 501 has a limited shifting range. The bristles on the surface of the cleaning brush sleeve 501 can contact the outside of the conveyor belt 2 and the back of the tile being conveyed at the same time when the driving roller 5 rotates, so that during the tile conveying process, the bristles can continuously brush the surface of the conveyor belt 2 to remove dust, debris and other impurities that may be attached, and gently brush away the floating dust on the back of the tile to maintain the cleanliness of the tile, so that the tile can be more smoothly attached to the conveyor belt 2 later. As the driving roller 5 rotates, the cleaning brush sleeve 501 continues to work, which not only improves the overall cleanliness of the tile conveyor line, but also reduces conveying failures caused by the accumulation of impurities, such as tile warping and jamming.

[0042] In a further embodiment of the present invention, an abutment rack 104 is fixedly connected to the top of the abutment rod 101, and the bottom of the abutment frame 402 abuts against the abutment rack 104. An air bag 408 is installed inside the hollow partition 401, and the bottom of the air bag 408 abuts against the top of the abutment frame 402. An air blowing hose 409 connected to the air bag 408 in the adjacent hollow partition 401 is installed on the top of the air bag 408, and the air blowing port of the air blowing hose 409 faces the conveyor belt 2. Specifically, when the abutment frame 402 moves and contacts the abutment rack 104 on the abutment rod 101, the teeth on the abutment rack 104 push the abutment frame 402 upward, and then the abutment frame 402 is pushed upward. When in the tooth groove position, the pressure frame 402 is lowered and reset by the force of the compression spring 413, and the reciprocating lifting of the pressure frame 402 is used to squeeze the airbag 408 in the hollow partition 401, so that the gas inside the airbag 408 is discharged through the blowing hose 409. The airbags 408 in two adjacent hollow partitions 401 are connected through the blowing hose 409, and the blowing port of the blowing hose 409 is just facing the tile stacking area on the conveyor belt 2. When the gas in the airbag 408 is compressed and ejected, multiple fine airflows are formed, which directly act on the conveyor belt 2 and the tiles thereon. This airflow helps to remove tiny dust and impurities on the surface of the tiles and the surface of the conveyor belt 2.

[0043] In a further embodiment of the present invention, a connecting seat 7 is slidably installed on the top of the pressure frame 402, and a connecting rod 701 is hinged on the connecting seat 7. The hinge point on the connecting rod 701 is located at the center of the connecting rod 701. A pulling frame 410 is installed on the top of the pressure plate 403 in the hollow partition 401. A through groove 411 is vertically opened on the pulling frame 410 for the end of the connecting rod 701 to be inserted. A connecting shaft rod 702 is fixedly connected to the central hinge point of the connecting rod 701. One end of the connecting shaft rod 702 passes through the hollow partition 401 and is fixedly connected to a cross bar 703. A connecting spring 704 is provided on the outer sleeve of the connecting shaft rod 702. The two ends of the connecting spring 704 are respectively against the cross bar 703 and the hollow partition 401. Specifically, the two ends of the connecting rod 701 are respectively inserted into the pulling frames 410 on the two pressure plates 403. When the pressure frame 402 moves up from the abutment rod 101, After opening, as the pressure frame 402 and the pressure plates 403 on both sides descend, the pressure plates 403 are pulled downward under the action of the tension spring 404, so that the pressure plates 403 on both sides simultaneously press the two tiles separated by the hollow partition 401. If the adjacent corners of the two tiles are on the same horizontal plane, the pulling frames 410 on both sides are just placed on the two ends of the connecting rod 701, so that the connecting rod 701 and the cross bar 703 connected to the connecting rod 701 are maintained in a relatively horizontal state. When the height difference between the adjacent corners of the two tiles is large, the pulling frames 410 on the pressure plates 403 on both sides will be at different heights, causing the connecting rod 701 and the cross bar 703 outside the hollow partition 401 to tilt. The staff can check the flatness of the tile corners by directly observing the state of the cross bar 703, thereby further ensuring the quality of the finished product after the tile is polished.

[0044] In a further embodiment of the present invention, a check rack 412 is fixedly connected to one side of the inner wall of the through groove 411, and the end of the connecting rod 701 is engaged with the check rack 412. The inner wall of the conveyor platform 1 is fixedly connected to a wedge-shaped baffle 105 that abuts against the cross bar 703. The position of the wedge-shaped baffle 105 is located above the feeding end of the conveyor belt 2. Specifically, under the action of the connecting spring 704 on the connecting shaft 702, the connecting seat 7 is forced to move with the connecting rod 701 in the direction of the check rack 412, so that the end of the connecting rod 701 is engaged with the check tooth groove on the check rack 412. After the pressure plate 403 descends to a suitable position to press the tiles, the pressure plate 403 is limited by the cooperation of the connecting rod 701 and the check rack 412 to prevent accidental loosening of the pressure plate 403 during the fixing process, thereby further improving the stability of the tile transportation process. When the cross bar 703 moves forward and abuts against the wedge-shaped baffle 105, the cross bar 703 will be squeezed into the hollow partition 401, so that the end of the connecting rod 701 and the check rack 412 are disengaged, and the pressure plate 403 can be lifted up when the abutment frame 402 is lifted up by the abutment rod 101 at the feeding end, so that another tile can be fixed again later.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
