Description

Technical Field

[0001] The present invention relates to the technical field of powder spreading equipment, and particularly relates to a powder spreading production line. Background Art

[0002] The high homogenization of the surface effects of ceramic tiles brought about by the popularization of inkjet technology has forced glaze material enterprises, equipment enterprises, and ceramic enterprises to rack their brains to find new ceramic tile decoration effects. With the application of dry particles in domestic ceramic enterprises, the situation of product homogenization brought about by the popularization of inkjet technology has been broken. The difference between dry particles and ordinary glazes is that dry particles themselves can achieve a relatively thick glaze layer effect. For this reason, the differences in the surface textures of ceramic tiles are more obvious, and the forms of expression of dry particles are also rich and diverse.

[0003] The combination of the application of dry particles and inkjet technology can achieve many effects, including not only color but also surface texture. Decorating products by spraying dry particles is better than spraying special inks. Through an inkjet printing device, glue is sprayed through a printing channel for precise positioning, then dry particles are sprinkled by a dry particle machine, and then the dry particles outside the glue area are sucked away by negative pressure, that is, the process of "spraying glue - sprinkling dry particles - sucking away the excess dry particles" is used to achieve the pattern of dry particles.

[0004] However, the surface of daily-use ceramics with dry particles is concave, and the traditional method of sucking dry particles by negative pressure is not applicable. Therefore, it is necessary to manually pick up the green body and perform a powder pouring operation to pour out the excess dry particles inside. Summary of the Invention

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "install", "connect", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0031] The following will Figures 1 to 7 describe the embodiments of the present invention.

[0032] As Figures 1 - 7 shown, this embodiment relates to a powder spreading production line, including a conveying line, a glue spraying assembly 100, a powder spreading mechanism 200, and a powder pouring mechanism.

[0033] Among them, the conveying line is used to convey workpieces. In this embodiment, the workpiece is a ceramic bowl. The glue spraying assembly 100 is used to spray glue on the workpieces on the conveying line; the powder spreading mechanism 200 is used to spread dry particles on the workpieces sprayed with glue on the conveying line; the powder pouring mechanism, the powder pouring mechanism includes a manipulator 3 and a driving device, the manipulator 3 is used to clamp the workpiece, and the driving device is used to drive the manipulator 3 to pour the dry particles inside the workpiece and place the workpiece on the conveying line.

[0034] Based on the above structure, during operation, the workpiece is placed on the conveying line, and the conveying line conveys the workpiece along a predetermined route. When the workpiece reaches the glue spraying station, the glue spraying assembly 100 performs a glue spraying operation on the workpiece at the glue spraying station. After the glue spraying operation is completed, the workpiece is conveyed by the conveying line to the next station. When it reaches the powder spreading station, the powder spreading mechanism 200 performs a dry particle spreading operation on the glue spraying position of the workpiece. After the dry particle spreading operation is completed, the workpiece is conveyed by the conveying line to the next station. When it reaches the powder pouring station, the manipulator 3 clamps the workpiece for a powder pouring operation, and the driving device drives the manipulator 3 to pour the excess dry particles that are not adhered by the colloid inside the workpiece. After pouring the dry particles, the driving device drives the manipulator 3 to place the workpiece back on the conveying line, and then the workpiece is conveyed by the conveying line to the next station.

[0035] It can be seen that the present invention conveys the workpiece through the conveying line, and then uses the glue spraying assembly 100 and the powder spreading mechanism 200 to perform glue spraying and dry particle spreading operations on the workpiece on the conveying line respectively. Then, using the manipulator 3 and the driving device in the powder pouring mechanism, the workpiece is clamped, the dry particles inside the workpiece are poured, and the workpiece is placed on the conveying line to replace manual powder pouring operations, realizing automated operations and improving production efficiency.

[0036] Among them, the driving device includes a horizontal rotation driving component, a lifting driving component, and an up-and-down swing driving component. The horizontal rotation driving component includes a rotating table 4, the lifting driving component includes a lifting plate 5, and the up-and-down swing driving component includes an up-and-down swing shaft 6. The lifting plate 5 is arranged on the rotating table 4, the up-and-down swing shaft 6 is rotatably arranged on the lifting plate 5, and the manipulator 3 is arranged at one end of the up-and-down swing shaft 6 away from the lifting plate 5. During operation, the workpiece is conveyed by the conveyor line to the powder pouring station, and the workpiece is located below the manipulator 3. The lifting plate 5 operates to drive the up-and-down swing shaft 6 and the manipulator 3 arranged on the up-and-down swing shaft 6 to move downward. Then, the manipulator 3 clamps the workpiece. After clamping, the lifting plate 5 operates to drive the manipulator 3 to move upward, so that the workpiece leaves the conveying surface of the conveyor line. Then, the rotating table 4 operates to rotate, driving the lifting plate 5, the up-and-down swing shaft 6, and the manipulator 3 arranged on the rotating table 4 to rotate. Thus, the workpiece leaves from above the conveyor line. Then, the up-and-down swing shaft 6 operates to drive the manipulator 3 to rotate, so as to drive the workpiece to rotate. Thus, by only presetting to rotate the workpiece to a suitable angle and position, the dry particles inside the workpiece can be smoothly poured. Thus, the powder pouring operation is completed. Then, through the reset movement of the up-and-down swing shaft 6, the lifting plate 5, and the rotating table 4, the workpiece can be placed back on the conveyor line to replace manual powder pouring operation, realizing automated operation and improving production efficiency.

[0037] Specifically, the horizontal rotation drive assembly further includes a base 7 and a drive motor 8, the lifting drive assembly further includes a lifting cylinder 9, and the vertical swing drive assembly further includes a bearing block 10, a swing plate 11, a connecting seat 12, and a drive cylinder 13. The turntable 4 is rotatably arranged on the base 7, the drive motor 8 is arranged on the base 7 and is in transmission connection with the turntable 4, the fixed end of the lifting cylinder 9 is arranged on the turntable 4, and the drive end of the lifting cylinder 9 is connected to the bottom of the lifting plate 5. The bearing block 10 and the connecting seat 12 are arranged on the lifting plate 5, the vertical swing shaft 6 is rotatably arranged on the bearing block 10, the swing plate 11 is arranged at one end of the vertical swing shaft 6 close to the lifting plate 5, the length direction of the drive cylinder 13 is perpendicular to the length direction of the vertical swing shaft 6, the fixed end of the drive cylinder 13 is hinged to the connecting seat 12, and the drive end of the drive cylinder 13 is hinged to the free end of the swing plate 11. During operation, the workpiece is conveyed by the conveyor line to the powder pouring station, and the workpiece is located below the manipulator 3. The drive end of the lifting cylinder 9 contracts to drive the lifting plate 5 and the components on the lifting plate 5 to move downward. Then, the manipulator 3 clamps the workpiece. After clamping, the drive end of the lifting cylinder 9 extends to drive the manipulator 3 to move upward, so that the workpiece leaves the conveying surface of the conveyor line. Then, the drive motor 8 operates to drive the turntable 4 to rotate relative to the base 7, thereby driving the components arranged on the turntable 4 to rotate. The workpiece leaves from above the conveyor line. Then, the drive end of the drive cylinder 13 extends to drive the swing plate 11 and the vertical swing shaft 6 to rotate relative to the bearing block 10 to drive the manipulator 3 to rotate, so as to drive the workpiece to rotate. Thus, by presetting to rotate the workpiece to an appropriate angle and position, the dry particles inside the workpiece can be smoothly poured, and the powder pouring operation is completed. Then, by driving the cylinder 13, the lifting cylinder 9, and the drive motor 8 to perform reset movement, the workpiece can be placed back on the conveyor line to replace manual powder pouring operation, realizing automatic operation and improving production efficiency. It should be noted that the fixed end of the drive cylinder 13 is hinged to the connecting seat 12, and the drive end of the drive cylinder 13 is hinged to the free end of the swing plate 11, so that the drive cylinder 13 has an angle adjustment margin. Therefore, when the drive end of the drive cylinder 13 extends and contracts, it will adaptively adjust its own angle to avoid jamming. Thus, the present solution can adopt a drive structure of a linear cylinder, which has the advantage of lower cost compared with using a motor and a rotary cylinder.

[0038] Among them, the conveyor line includes a first conveyor section 14 and a second conveyor section 15. There is a spacing 16 between the first conveyor section 14 and the second conveyor section 15. The first conveyor section 14, the rotating table 4, and the second conveyor section 15 are arranged in sequence along the conveying direction of the workpiece. There are at least three sets of the lifting plate 5, the up-and-down swing shaft 6, and the manipulator 3. At least three sets of the lifting plates 5 are arranged circumferentially along the rotating table 4. One set of the manipulator 3 is located above the first conveyor section 14, one set of the manipulator 3 is beside the spacing 16, and one set of the manipulator 3 is located above the second conveyor section 15. In this embodiment, the workpiece is conveyed from the first conveyor section 14 towards the second conveyor section 15. The rotating table 4 is located above the spacing 16. There are four sets of the lifting plate 5, the up-and-down swing shaft 6, and the manipulator 3. The four sets of the lifting plates 5 are evenly distributed circumferentially along the rotating table 4. One set of the manipulator 3 is located above the first conveyor section 14, one set of the manipulator 3 is beside the spacing 16, one set of the manipulator 3 is beside the other side of the spacing 16, and one set of the manipulator 3 is located above the second conveyor section 15. During operation, the manipulator 3 above the first conveyor section 14 is at the first station, the manipulator 3 beside the spacing 16 is at the second station, the manipulator 3 above the second conveyor section 15 is at the third station, and the manipulator 3 beside the other side of the spacing 16 is at the fourth station. Among them, the first station is used to clamp the workpiece, the second station is used to pour the dry particles inside the workpiece, the third station is used to release the workpiece and place it on the second conveyor section 15, and the fourth station is used for the manipulator 3 to be in a waiting state. In this way, only by rotating the rotating table 4, the operations of clamping the workpiece, pouring the dry particles inside the workpiece, releasing the workpiece, and the waiting state can be carried out simultaneously, improving the overall working efficiency of the production line.

[0039] Among them, the manipulator 3 includes a mounting bracket 17 and clamping fingers 18. The mounting bracket 17 is connected to the driving device. An air nozzle 19 is arranged on the mounting bracket 17. The air nozzle 19 is communicated with the inside of the mounting bracket 17. There are at least two clamping fingers 18. At least two clamping fingers 18 are movably arranged on the mounting bracket 17. In this embodiment, there are four clamping fingers 18. The air nozzle 19 is used to supply air into the inside of the mounting bracket 17 to drive the clamping fingers 18 to clamp the workpiece. That is to say, the manipulator 3 is a pneumatic manipulator 3. When in use, the air nozzle 19 is externally connected to a gas supply device. The gas supply device supplies air into the inside of the mounting bracket 17 through the air nozzle 19 to drive the clamping fingers 18 to clamp the workpiece. Using a pneumatic manipulator 3 is not easy to damage the workpiece and avoid causing waste products during production.

[0040] Among them, the structure of the finger 18 has various forms. In one embodiment, the finger 18 includes a mounting portion 20, a first bending portion 21, and a second bending portion 22. The mounting portion 20 is movably arranged on the mounting bracket 17. The first bending portion 21 is connected to the mounting portion 20 and is bent relative to the mounting portion 20. The second bending portion 22 is connected to the first bending portion 21 and is bent relative to the first bending portion 21. The mounting portion 20, the first bending portion 21, and the second bending portion 22 are integrally in a Z shape. That is, the finger 18 is in a rigid form. By setting the first bending portion 21 and the second bending, the finger 18 is integrally in a Z shape, which is beneficial for more firmly clamping the workpiece and preventing it from falling. Among them, a soft rubber pad 26 is arranged on the inner side of the fingertip of the finger 18. When the soft rubber pad 26 contacts the workpiece, it can increase the friction force, firmly clamp the workpiece, and prevent it from falling. At the same time, it can also play a buffering role during clamping, not easily damage the workpiece, and avoid causing waste during production.

[0041] Among them, as Figures 6 - 7 shown, at least two fingers 18 are arranged oppositely. In this embodiment, four fingers 18 are arranged, and every two fingers 18 are arranged oppositely. Among them, the structure of the finger 18 has various forms. In another embodiment, the finger 18 is made of an elastic material, the shape of the finger 18 is arc-shaped, and an air vent cavity is arranged inside the finger 18. The air vent cavity is communicated with the inside of the mounting bracket 17. The air nozzle 19 is used to ventilate the inside of the mounting bracket 17 and the air vent cavity to drive the fingertips of the finger 18 to approach each other or move away from each other. That is, the finger 18 is made of an elastic material. By ventilating the inside of the mounting bracket 17 and the air vent cavity through the air nozzle 19, the finger 18 deforms, realizing two working forms of the fingertips of the finger 18 approaching each other or moving away from each other. Thus, the fingertips of the finger 18 are used to approach each other to clamp the workpiece, and the fingertips of the finger 18 are used to move away from each other to loosen the workpiece. Compared with the traditional rigid finger 18 structure, it has the advantages of simple structure and low cost.

[0042] Among them, the manipulator 3 further includes a first adjusting rod 27. Displacement adjusting holes are arranged along the length direction of the first adjusting rod 27, and the mounting bracket 17 is arranged on the displacement adjusting holes. In this way, by adjusting the position of the mounting bracket 17 on the displacement adjusting holes, the position of the finger 18 can be adjusted, thereby realizing the adjustment of the distance 16 between the two fingers 18 and meeting the requirements of different workpiece sizes, so as to improve the adjustment function of the manipulator 3. In this embodiment, the manipulator 3 further includes a second adjusting rod. The first adjusting rod 27 and the second adjusting rod are arranged in a cross shape. Four fingers 18 are arranged, and two of the fingers 18 are arranged on the first adjusting rod 27, and the other two fingers 18 are arranged on the second adjusting rod. In this way, it is more beneficial to firmly clamp the workpiece by the four fingers 18 and prevent it from falling.

[0043] Among them, the powder spreading production line further includes a dry granule recycling device. The dry granule recycling device includes a recycling hopper 23, a vacuum feeder 24 and a hoist 25. The recycling hopper 23 is arranged on one side of the powder pouring mechanism. A filter screen is arranged inside the recycling hopper 23. The feeding port of the vacuum feeder 24 is communicated with the discharging port of the recycling hopper 23 through a pipeline. The discharging port of the vacuum feeder 24 corresponds to the storage hopper of the hoist 25. The discharging port of the hoist 25 is used to supply dry granules to the storage hopper of the powder spreading mechanism 200. During operation, the manipulator 3 pours the dry granules inside the workpiece into the recycling hopper 23. The dry granules pass through the filter screen and fall to the discharging port of the recycling hopper 23, while the impurities are filtered by the filter screen. Then, the vacuum feeder 24 sucks the dry granules at the discharging port of the recycling hopper 23 to the discharging port of the vacuum feeder 24 through vacuum suction. The discharging port of the vacuum feeder 24 corresponds to the storage hopper of the hoist 25. Therefore, by only setting a valve body, it can control the dry granules to fall into the storage hopper of the hoist 25. Then, through the lifting action of the hoist 25, the dry granules at the low position are conveyed to the high position, and the discharging port of the hoist 25 is made to correspond to the storage hopper of the powder spreading mechanism 200, so as to supply dry granules to the storage hopper of the powder spreading mechanism 200, realizing the recycling and reuse of dry granules.
