Description

Technical Field

[0001] This utility model relates to the field of ceramic tile processing technology, specifically to an automatic marking device. Background Technology

[0002] Tiles are a type of acid- and alkali-resistant building or decorative material made from refractory metal oxides and semi-metal oxides through grinding, mixing, pressing, glazing, and sintering. The back of each tile is printed with labels, icons, and other information. Some high-quality tiles require secondary processing before sale, necessitating the removal of these labels. For some tile label removal operations, workers use a handheld grinder. During grinding, the worker first flips the tile over, then starts the grinder and applies its grinding head to the label on the back of the tile. However, manual grinding is slow, and prolonged exposure to the dust generated during grinding puts a heavy burden on the worker's health. Therefore, we propose an automated label removal device.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-5 This embodiment provides a technical solution:

[0033] An automatic marking device includes a frame 1 for supporting the main body of the device, a limiting mechanism for guiding and limiting the tiles, a double-row synchronous belt conveyor 14 for conveying the tiles, and a marking mechanism for marking the lower markings on the tiles. The marking mechanism is installed below the double-row synchronous belt conveyor 14 and includes a lifting component and a lifting component position adjustment unit. The lifting component position adjustment unit is used to adjust the position of the lifting component so that it contacts the tile, and can also adjust the position of the lifting component according to different tile sizes or different marking positions.

[0034] It also includes a controller 2, which is located outside the frame 1 or fixedly mounted on the frame 1, and the input terminal of the controller 2 is electrically connected to an external power supply.

[0035] Example 1:

[0036] An automatic marking device includes a frame 1. A fixed bracket 4 is located on the upper left side of the frame 1. An electro-hydraulic actuator 5 is located in the middle of the fixed bracket 4. A mounting bracket 6 is located between the telescopic ends of the electro-hydraulic actuator 5. A uniformly distributed guide wheel 7 is rotatably connected to the lower side of the mounting bracket 6 via a bearing. The device also includes a controller 2 located outside the frame 1. The input end of the controller 2 is electrically connected to an external power source, and the input end of the electro-hydraulic actuator 5 is electrically connected to the output end of the controller 2. Two connecting brackets 8 are located in the middle of the upper side of the frame 1. Two longitudinally symmetrically distributed arc-shaped seats 12 are installed between the connecting brackets 8. A uniformly distributed guide wheel 13 is rotatably connected to the upper side of the arc-shaped seats 12 via a bearing. Rectangular grooves 9 are formed at both the front and rear ends of the upper side of the connecting brackets 8. Bolts 10 are inserted into the rectangular grooves 9. The upper end of the bolt 10 is fixedly connected to the lower side of the adjacent arc-shaped seat 12. A nut 11 is threaded into the middle of the bolt 10, and the nut 11 is fitted into the adjacent rectangular groove 9. Double-row synchronous belt conveyors 14 are provided on both the upper left and right sides. The input end of the double-row synchronous belt conveyor 14 is electrically connected to the output end of the controller 2. When grinding and removing the label on the back of the tile, the tile whose label needs to be removed is first horizontally conveyed to the upper left end of the double-row synchronous belt conveyor 14 on the right side through external equipment. The controller 2 starts the double-row synchronous belt conveyors 14 on the left and right sides to run. The double-row synchronous belt conveyor 14 runs through the meshing transmission of the synchronous belt and the synchronous wheel, so that the two horizontally distributed synchronous belts inside move synchronously. Through the contact friction between the lower side of the tile and the synchronous belt, the tile is driven to move horizontally to the left. When the tile whose label needs to be ground enters the synchronous belt of the double-row synchronous belt conveyor 14 on the left side from the synchronous belt of the double-row synchronous belt conveyor 14 on the right side, during this process, the front and rear ends of the tile slide in contact with the corresponding guide wheel 13. The guide wheel 13 limits the longitudinal movement of the tile to prevent it from moving horizontally.When the tile moves to the left-side double-row synchronous belt conveyor 14, the upper side of the tile contacts the lower outer side of the guide wheel 7. The guide wheel 7 vertically limits the tile's rightward movement, ensuring it fits onto the synchronous belt of the left-side double-row synchronous belt conveyor 14, facilitating subsequent marking operations. After marking, the tile is then conveyed to the next process via the synchronous belt of the left-side double-row synchronous belt conveyor 14. During the operation of the automatic marking equipment, the controller 2 activates the electro-hydraulic push rod 5, causing its telescopic end to drive the guide wheel 7 vertically via the mounting bracket 6. This adjusts the vertical limit gap between the guide wheel 7 and the synchronous belt of the left-side double-row synchronous belt conveyor 14 according to changes in tile thickness. Simultaneously, the operator rotates the nut 11, which is threaded onto the bolt 10, moving it away from the head of the bolt 10. This releases the bolt 10 and nut 11 from their engagement with the rectangular groove 9. The fixed connection is made (when the bolt 10 and nut 11 are fixedly connected to the rectangular groove 9, the upper side of the head of the bolt 10 is pressed against the lower outer edge of the rectangular groove 9, and the lower side of the nut 11 is pressed against the upper outer edge of the rectangular groove 9. Through the cooperation of the head of the bolt 10 and the nut 11, they are pressed against the rectangular groove 9, thereby achieving the fixation between the three and thus fixing the arc seat 12). Then, the arc seat 12 is moved to drive the bolt 10 to move longitudinally along the rectangular groove 9, thereby adjusting the tile conveying guide distance between the front and rear guide wheels 13 according to the change of tile width. Then, the arc seat 12 is fixed to the corresponding connecting frame 8 again through the same principle. This device, through the transmission element, can adjust the position of the tile grinding mark guide limit part in the device according to the change of the tile size itself, improve the application range of the tile grinding mark of the device, and also includes a grinding mark mechanism.

[0037] The grinding mechanism is an inclined grinding mechanism 3. The inclined grinding mechanism 3 includes a connecting seat 31, a slide rail 32, a connecting seat 33, a connecting seat 34, a lifting component 35, and a lateral movement component 36. There are three connecting seats 31, which are located inside the frame 1. A slide rail 32 is located on the upper side of each connecting seat 31, and a connecting seat 33 is connected to the slide rail 32. Connecting seats 34 are located on both the left and right sides of the upper side of the connecting seat 33. A lifting component 35 is located on the upper side of the connecting seat 34. A lateral movement component 36 is located between the connecting seat 33 and the frame 1. The lifting component 35 includes a support frame 351, a rotating shaft 352, a support plate 353, a grinding machine 354, a rotating shaft 355, a rotating shaft 356, and... An electro-hydraulic actuator 357 and a support frame 351 are respectively disposed on the upper side of a connecting seat 34. The upper end of the support frame 351 is rotatably connected to a support plate 353 via a rotating shaft 352. A grinder 354 is disposed on the upper side of the support plate 353 near the lateral center of the connecting seat 33. A rotating shaft 356 is rotatably connected to the upper side of the connecting seat 34 away from the lateral center of the connecting seat 33 via a bearing 2. A rotating shaft 355 is rotatably connected to the lower side of the support plate 353 away from the lateral center of the connecting seat 33 via a bearing 3. An electro-hydraulic actuator 357 is disposed between the rotating shaft 355 and the vertically adjacent rotating shaft 356. The input ends of the electro-hydraulic actuator 357 and the grinder 354 are electrically connected to the output end of the controller 2. The lateral movement assembly 36 includes a connecting seat. The components include four 361, stud 362, connecting seat 363, and handwheel 364. Connecting seat 361 is located on the front and rear sides of the middle left side of frame 1. The lower end of connecting seat 361 is rotatably connected to stud 362 via bearing 4. Connecting seat 363 is located in the middle of the lower side of connecting seat 33. Stud 362 is threadedly connected to the longitudinally adjacent connecting seat 363. Handwheel 364 is located at the opposite end of stud 362. When the tile moves to the grinding mark position (during this process, a photoelectric sensor is installed inside the device to detect the position of the tile. The photoelectric sensor uses a common method in existing technology to detect the position of the tile using light signals and transmits the detected tile model to controller 2 in the form of an electrical signal), then the control... Device 2 starts the grinder 354 and the electro-hydraulic actuator 357. The telescopic end of the electro-hydraulic actuator 357 moves upward and rotates in conjunction with the rotating shaft 355 (the grinder 354 drives the corresponding grinding wheel to rotate via its own motor, using the grinding force generated by the high-speed rotation of the grinding wheel to achieve the grinding operation). This causes the support plate 353 to rotate upward around the axis of the corresponding rotating shaft 352 (during this process, the fixed end of the electro-hydraulic actuator 357 rotates adaptively around the axis of the corresponding rotating shaft 356, and the telescopic end of the electro-hydraulic actuator 357 rotates adaptively around the axis of the corresponding rotating shaft 355). This causes the grinding part of the grinder 354 to tilt upward and lift up to contact the bottom of the tile, thus performing a grinding mark operation on the bottom of the tile. After the grinding mark on the bottom of the tile is completed,Controller 2 controls the retraction end of electro-hydraulic actuator 357 to reset, restoring grinder 354 to its initial state. Then, controller 2 starts the left-side double-row synchronous belt conveyor 14, which transports the marked tiles to other processes. During operation of the automatic grinding equipment, the operator can rotate handwheel 364 according to the tile's volume, causing the corresponding stud 362 to rotate. During rotation, stud 362, through a threaded connection, drives the corresponding connecting seat 363 to move longitudinally. Connecting seat 363 then drives the corresponding connecting seat 33 to move longitudinally along the corresponding slide rail 32. This allows for longitudinal adjustment of the grinding points of grinder 354 at both ends according to the tile's size, making the device suitable for grinding different types of tiles. When using the automatic grinding equipment, it can... A corrugated tube is installed between the connecting seat 4 361 and the longitudinally adjacent connecting seat 5 363, as well as between the opposing inner surfaces of the two connecting seats 5 363. The corrugated tube is movably sleeved on the outer end of the adjacent stud 1 362, providing dust protection to the exposed parts of the stud 1 362 and preventing dust and other impurities from interfering with its transmission. The corrugated tube is a corrugated structure made of multiple layers of stacked metal sheets. Its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance. This device, through the cooperation of its components, can automatically transport and mark tiles without manual intervention, improving tile marking efficiency. Simultaneously, through transmission elements, the device can adjust the position of the tile marking part according to changes in the tile's size and label position, expanding the device's applicability for tile marking.

A handwheel 1583 is located at the end of the stud 1582 furthest from the longitudinal center of the frame 1. The input ends of the grinder 1563 and the electro-hydraulic actuator 1566 are electrically connected to the output end of the controller 2. The vertical lifting grinding mechanism 15 performs grinding operations on the bottom of the ceramic tile. During this process, the controller 2 starts the grinder 1563 and the electro-hydraulic actuator 1566. The telescopic end of the electro-hydraulic actuator 1566 extends, driving the trapezoidal slider 1565 to slide along the slide rail 1564. As the trapezoidal slider 1565 moves, it presses upwards against the pulley 1568, which is in vertical contact with it, through its own trapezoidal inclined surface.The pulley 1568 indirectly drives the corresponding grinder 1563 vertically upward via the lifting frame 1562 along the slide rail 4 1561. The pulley 1568 then presses upward along the inclined surface of the trapezoidal slider 1565, thus achieving the grinding operation on the bottom of the tile. When adjusting the lateral position of the grinding point of the left-side grinder 1563, the operator rotates the handwheel 1573, causing it to drive the gear 1572 to rotate via the auxiliary shaft 1571. The gear 1572 engages with the rack plate 1574, causing the left-side L-shaped plate 155 to move along the corresponding slide rail 3 1563. 4. The corresponding grinding machine 2 (1563) is moved laterally to adjust the grinding point position. When adjusting the grinding distance between two adjacent grinding machines 2 (1563), the operator rotates the left handwheel 3 (1583) to make it slide longitudinally along the corresponding slide rail 2 (152) via the threaded connection to the corresponding longitudinal sliding seat 153. This allows for longitudinal adjustment of the grinding point position of the grinding machines 2 (1563) at both ends according to the size of the tile, making the device suitable for grinding different types of tiles. After grinding the bottom of a single tile, the controller 2 controls the electro-hydraulic push rod 3 (1566) to reset its extension end.

The lifting component 3 166 includes a slide rail 8 1661, a lifting frame 2 1662, a grinding machine 3 1663, and an electro-hydraulic push rod 4 1664. The transverse moving component 2 167 includes an auxiliary shaft 2 1671, a gear 2 1672, a handwheel 4 1673, and a rack plate 2 1674. The transverse moving component 3 168 includes a connecting seat 9 1681, a stud 3 1682, and a handwheel 5 1683. The connecting seat 8 161 is located inside the frame 1, and the upper side of the connecting seat 8 161 is provided with a slide rail 6 162. A longitudinal sliding seat 2 163 is slidably connected between them. A slide rail 7 164 is provided on the upper side of the longitudinal sliding seat 2 163. An L-shaped plate 2 165 is slidably connected to the outer sides of slide rail 7 164 and the two rightmost slide rails 6 162. A slide rail 8 1661 is provided on the side wall of L-shaped plate 2 165. A lifting frame 2 1662 is slidably connected to the outer side of slide rail 8 1661. A grinding machine 3 1663 is provided on the upper side of lifting frame 2 1662. The bottom wall of L-shaped plate 2 165 is fixedly connected to the lower side of lifting frame 2 1662 via the telescopic end of electro-hydraulic push rod 4 1664. An auxiliary shaft 2 1671 is rotatably connected to the bottom wall of the left L-shaped plate 2 165 via bearing 8. A gear 2 1672 is provided in the middle of the bottom wall of auxiliary shaft 2 1671. A gear 2 1672 is provided at the opposite end of auxiliary shaft 2 1671. The machine has a handwheel 1673, a rack plate 1674 on the upper side of the longitudinal shift seat 163, a gear 1672 meshing with the adjacent rack plate 1674, and evenly distributed connecting seats 1681 inside the frame 1. A stud 1682 is rotatably connected to the middle of the connecting seat 1681 via a bearing 1682. The longitudinal shift seat 163 and L-shaped plate 165 are threadedly connected to the adjacent stud 1682. A handwheel 1683 is located at the end of the stud 1682 furthest from the longitudinal center of the frame 1. The input ends of the grinder 1663 and the electro-hydraulic actuator 1664 are electrically connected to the output end of the controller 2. The vertical lifting grinding mechanism 16 performs grinding operations on the bottom of the ceramic tile. During this process, the controller 2 activates the electro-hydraulic actuator 1664 and the grinder 1673. 663. The telescopic end of the electro-hydraulic actuator four 1664 extends, thereby driving the corresponding lifting frame two 1662 to move vertically upward along the slide rail eight 1661. The lifting frame two 1662 drives the corresponding grinder three 1663 to move vertically upward, so that the grinding part of the grinder three 1663 contacts the bottom of the tile by moving upward, thereby realizing the grinding operation. When adjusting the horizontal position of the grinding point of the left grinder three 1663, the operator turns the handwheel four 1673, which drives the gear two 1672 to rotate through the auxiliary shaft two 1671. The gear two 1672 is connected to the adjacent rack plate two 1674 through meshing, so that the L-shaped plate two 165 on the left side drives the corresponding grinder three 1663 on the left side to move laterally along the slide rail seven 164.To adjust the lateral position of the grinding point of the left-side grinder 3 1663, and to adjust the grinding distance between two longitudinally adjacent grinders 3 1663, the operator rotates handwheel 5 1683, causing stud 3 1682 to rotate. During the rotation of stud 3 1682, the corresponding longitudinal sliding seat 2 163 or the right-side L-shaped plate 2 165 moves longitudinally along the corresponding slide rail 6 162 via a threaded connection, thus adjusting the longitudinal grinding distance between the two longitudinally adjacent grinders 3 1663.

[0046] The working principle of the automatic marking equipment provided by this utility model is as follows: When grinding and removing the label on the back of a tile, the tile whose label needs to be removed is first horizontally conveyed to the upper right end of the double-row synchronous belt conveyor 14 on the left side by an external device. The controller 2 starts the double-row synchronous belt conveyors 14 on both the left and right sides to run. The double-row synchronous belt conveyor 14 runs through the meshing transmission of the synchronous belt and the synchronous wheel, so that the two horizontally distributed synchronous belts inside move synchronously. Through the contact friction between the bottom side of the tile and the synchronous belt, the tile is driven to move horizontally to the left. When the tile moves to the double-row synchronous belt conveyor 14 on the right side, the upper side of the tile contacts the lower outer side of the guide wheel 7. The guide wheel 7 vertically limits the rightward movement of the tile, so that it fits against the synchronous belt of the double-row synchronous belt conveyor 14 on the left side, which facilitates the subsequent marking operation. When the tile moves to the marking position, the marking mechanism performs the marking operation on the bottom of the tile. The position of the marking mechanism can be adjusted according to the different sizes of tiles or the position of different bottom marks. The grinding mechanism has three designs.

[0047] (1) The bottom of the tile is ground using the tilting grinding mechanism 3. During this process, the controller 2 starts the grinding machine 354 and the electro-hydraulic push rod 357. The telescopic end of the electro-hydraulic push rod 357 moves upward and is connected to the rotating shaft 355 (the grinding machine 354 drives the corresponding grinding wheel to rotate through its own motor, and the grinding operation is achieved by using the grinding force generated by the high-speed rotation of the grinding wheel). This causes the support plate 353 to rotate upward around the axis of the corresponding rotating shaft 352 (during this process, the fixed end of the electro-hydraulic push rod 357 rotates adaptively around the axis of the corresponding rotating shaft 356, and the telescopic end of the electro-hydraulic push rod 357 rotates adaptively around the axis of the corresponding rotating shaft 355). This causes the grinding part of the grinding machine 354 to move upward. The device tilts upwards and lifts to contact the bottom of the tile, thus performing a grinding operation on the bottom of the tile. After the bottom of the tile is ground, the controller 2 controls the telescopic end of the electro-hydraulic push rod 357 to reset, so that the grinder 354 returns to its initial state. The operator can rotate the handwheel 364 according to the volume of the tile to drive the corresponding stud 362 to rotate. During the rotation of the stud 362, the corresponding connecting seat 363 moves longitudinally through the threaded connection. The connecting seat 363 drives the corresponding connecting seat 33 to move longitudinally along the corresponding slide rail 32. Thus, the longitudinal position of the grinding points of the grinder 354 at both ends can be adjusted according to the size of the tile, making the device suitable for grinding operations on different types of tiles.

[0048] (2) The bottom of the tile is ground using the vertical lifting grinding mechanism 15. During this process, the controller 2 starts the second grinding machine 1563 and the third electro-hydraulic push rod 1566. The telescopic end of the third electro-hydraulic push rod 1566 extends and drives the trapezoidal slider 1565 to slide along the fifth slide rail 1564. During the movement of the trapezoidal slider 1565, it pushes the pulley 1568 vertically against it through its own trapezoidal inclined surface. This causes the pulley 1568 to indirectly drive the corresponding second grinding machine 1563 to move vertically upward through the lifting frame 1562 along the fourth slide rail 1561. The grinding operation on the bottom of the tile is achieved by the pulley 1568 pushing and moving upward along the inclined surface of the trapezoidal slider 1565. When adjusting the horizontal position of the grinding point of the second grinding machine 1563 on the left, the operator turns the second handwheel 1573 to make it pass through Auxiliary shaft 1571 drives gear 1572 to rotate. Gear 1572 meshes with rack plate 1574, causing L-shaped plate 155 on the left to move the corresponding grinding machine 1563 laterally along the corresponding slide rail 154. When adjusting the grinding distance between two adjacent grinding machines 1563, the operator rotates the left handwheel 1583 to make it slide longitudinally along the corresponding slide rail 152 via the threaded connection of the corresponding longitudinal shift seat 153. This allows for longitudinal adjustment of the grinding points of the grinding machines 1563 at both ends according to the size of the tile, making the device suitable for grinding different types of tiles. After grinding the bottom of a single tile, controller 2 controls the electro-hydraulic push rod 1566 to reset its extension end.

[0049] (3) The bottom of the tile is ground using the vertical lifting grinding mechanism 16. During this process, the controller 2 starts the electro-hydraulic push rod 1664 and the grinding machine 1663. The telescopic end of the electro-hydraulic push rod 1664 extends, thereby driving the corresponding lifting frame 1662 to move vertically upward along the slide rail 1661. The lifting frame 1662 drives the corresponding grinding machine 1663 to move vertically upward, so that the grinding part of the grinding machine 1663 contacts the bottom of the tile by moving upward, thereby realizing the grinding operation. When adjusting the horizontal position of the grinding point of the grinding machine 1663 on the left, the operator turns the handwheel 1673 to drive the gear 1672 to rotate through the auxiliary shaft 1671. The gear 1672 rotates through the adjacent rack plate 1674. The meshing connection between the two allows the L-shaped plate 2 165 on the left to move laterally along the slide rail 7 164, driving the corresponding grinding machine 3 1663 on the left to move laterally, thus adjusting the lateral position of the grinding point of the grinding machine 3 1663. When adjusting the grinding distance between two longitudinally adjacent grinding machines 3 1663, the operator rotates the handwheel 5 1683 to drive the stud 3 1682 to rotate. During the rotation of the stud 3 1682, the corresponding longitudinal sliding seat 2 163 or the L-shaped plate 2 165 on the right moves longitudinally along the corresponding slide rail 6 162 through the threaded connection, thus adjusting the longitudinal grinding distance between two longitudinally adjacent grinding machines 3 1663. At the same time, the controller 2 activates the electro-hydraulic push rod 2 5, causing its telescopic end to move vertically through the mounting bracket 6, driving the guide wheel 1 7 to move from... The vertical limiting gap between guide roller 7 and the synchronous belt of the left double-row synchronous belt conveyor 14 is adjusted according to the change in tile thickness. Then, controller 2 starts the double-row synchronous belt conveyors 14 on both sides. The right double-row synchronous belt conveyor 14 conveys the marked tile to the left onto the synchronous belt of the left double-row synchronous belt conveyor 14. When the marked tile moves to the left from the synchronous belt of the left double-row synchronous belt conveyor 14 and leaves the equipment, both the front and rear ends of the tile slide in contact with the corresponding guide roller 13. The guide roller 13 limits the longitudinal movement of the tile to prevent horizontal deviation. The device can automatically perform marking operations on the bottom of the tile, which is convenient to use. At the same time, the operator turns the nut. 11 moves away from the head of bolt 10 by being threaded into bolt 10, thereby releasing the fixed connection between bolt 10 and nut 11 and rectangular groove 9 (when bolt 10 and nut 11 are fixedly connected to rectangular groove 9, the upper side of the head of bolt 10 is in contact with the lower outer edge of rectangular groove 9, and the lower side of nut 11 is in contact with the upper outer edge of rectangular groove 9. The head of bolt 10 and nut 11 cooperate to make contact with rectangular groove 9, thereby fixing the three together and thus fixing the arc-shaped seat 12). Then, the arc-shaped seat 12 is moved to drive bolt 10 to move longitudinally along rectangular groove 9, thereby adjusting the tile conveying guide distance between the front and rear sets of guide rollers 13 according to the change of tile width.Subsequently, the arc-shaped seat 12 is fixed to the corresponding connecting frame 8 using the same principle. When the automatic marking equipment is in use, a bellows can be movably fitted onto the outside of the stud. The bellows wraps around the exposed part of the stud to prevent dust and other impurities from interfering with the stud's transmission. The bellows is a corrugated structure made of multiple layers of stacked metal sheets. Its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance.
