Description

Technical Field

[0001] This utility model relates to the field of ceramic tile spraying technology, and in particular to an automatic spraying device for anti-slip layer of ceramic tiles. Background Technology

[0002] In the field of building decoration materials, ceramic tiles are widely used for floor and wall decoration due to their aesthetic appeal and durability. With the upgrading of market demands, consumers are increasingly requiring higher functionalities from ceramic tiles, especially anti-slip performance, which has become a core indicator for damp environments such as bathrooms, kitchens, and outdoors. Currently, mainstream anti-slip ceramic tiles are typically manufactured using a surface-spraying anti-slip layer process, which increases the coefficient of friction by attaching materials such as metal particles and anti-slip coatings to the tile surface.

[0003] Among them, Chinese Patent No. CN216879992U discloses an automatic spraying device for anti-slip layer on ceramic tiles. It includes a fixed slide rail and a movable slide rail, with the movable slide rail slidably mounted on the fixed slide rail and having one rail. It also includes a spraying component and a positioning ruler. Both ends of the spraying component are slidably connected to the fixed and movable slide rails, respectively. The spraying component includes a left air outlet, a right air outlet, a flexible connecting pipe, and a drive component. Both ends of the left air outlet are slidably connected to the fixed and right air outlets, respectively. The second end of the right air outlet is slidably connected to the movable slide rail. The bottom end of the flexible connecting pipe is fixedly connected to the left and right air outlets. The flexible connecting pipe is made of a flexible material. The drive component is fixedly mounted on the fixed slide rail, and its drive end is fixedly connected to the spraying component. Both ends of the positioning ruler are slidably connected to the fixed and movable slide rails, respectively. This application solves the defect of uneven spraying caused by inaccurate tile positioning, which is still present in this application.

[0004] The device adjusts the length of the spraying component to match the width of the tile by using fixed and movable slide rails. However, the spraying component only uses left and right air outlets and flexible connecting pipes, lacking a core atomizing component (such as a spray nozzle). When the paint is delivered to the air outlet by external equipment, due to the lack of atomization power and precise control of the nozzle, the paint is easily sprayed out in the form of liquid accumulation or particle scattering, resulting in uneven coating thickness on the tile surface. Therefore, we propose an automatic anti-slip layer spraying device for tiles. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic spraying device for anti-slip layer of ceramic tiles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic anti-slip coating device for ceramic tiles includes a base, with fixed plates vertically fixed to both sides of the top of the base. A clamping assembly that adapts to the size of the ceramic tile is provided between the two fixed plates. The clamping assembly achieves positioning and clamping of ceramic tiles of different sizes through a hydraulic drive mechanism.

[0008] The top of the fixed plates on both sides is equipped with a dual-track synchronous moving assembly. The top of the moving assembly is connected to a support frame. The top of the support frame is equipped with a first hydraulic cylinder. The bottom output end of the first hydraulic cylinder passes through the bottom of the support frame and is connected to a spraying assembly. An industrial-grade PLC controller is installed on one side of the support frame. The controller has a built-in anti-slip layer spraying process algorithm, which can automatically match the spraying parameters according to the material and size of the tile.

[0009] As a preferred embodiment of this utility model, the clamping assembly includes two clamping plates symmetrically arranged inside the fixed plate. A second hydraulic cylinder is provided on the outer wall of both sides of the fixed plate, and the output end of the second hydraulic cylinder passes through the inner wall of the fixed plate and is fixedly connected to the clamping plate.

[0010] As a preferred embodiment of this utility model, auxiliary directional slide rods are provided on both sides of the two fixed plates and on the front and back of the second hydraulic cylinder. One end of each auxiliary directional slide rod passes through the inner wall of the fixed plate and is fixedly connected to the clamping plate.

[0011] As a preferred embodiment of this utility model, the inner surface of the clamping plate is provided with a rubber protective pad, the clamping plate is provided with a pressure sensor, and one end of the front side of the clamping plate is provided with an ultrasonic edge detection sensor.

[0012] As a preferred embodiment of this utility model, the movable component includes movable mounting seats fixedly mounted on two fixed plates. Each of the two movable mounting seats has a T-shaped groove extending through the top. A T-shaped slider is slidably connected in each T-shaped groove. A lead screw is provided in one T-shaped groove, and a straight guide tube is provided in the other T-shaped groove.

[0013] As a preferred embodiment of this utility model, the lead screw on one side is threadedly connected to one of the T-shaped sliders, and the linear guide tube on the other side is slidably connected to another T-shaped slider. A drive motor is provided on the back of the movable mounting base on one side, and its output end is connected to one end of the lead screw for transmission.

[0014] As a preferred embodiment of this utility model, the spraying assembly includes a spraying bracket connected to the output end of the first hydraulic cylinder. The bottom of the spraying bracket is provided with multiple nozzles, and each of the multiple nozzles is provided with an electromagnetic control valve. The other side of the top of the spraying bracket is provided with a flexible hose connected to an external paint spraying mechanism.

[0015] As a preferred embodiment of this utility model, a laser rangefinder sensor is provided on the front side of the spraying bracket.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the spraying assembly is equipped with multiple nozzles, each with an electromagnetic control valve. The top of each nozzle is connected to an external material supply mechanism via a flexible hose. The hose delivers paint to the pressure equalization chamber inside the spraying bracket. The nozzle design provides atomization power and precise control, enabling the paint to be evenly atomized and sprayed. Simultaneously, a laser rangefinder on the front of the spraying bracket measures the distance between the spraying bracket and the tile surface in real time, feeding back to the PLC controller to adjust the height of the first hydraulic cylinder. This ensures a constant spraying distance and avoids uneven coating thickness due to height fluctuations. With the combined use of the nozzles, electromagnetic control valves, and laser rangefinder, the problem of liquid accumulation or particle scattering during paint spraying is solved, ensuring the uniformity of the coating thickness on the tile surface.

[0018] The design of the clamping assembly, including the symmetrical clamping plate, the second hydraulic cylinder, and the auxiliary directional slide, allows the second hydraulic cylinder to drive the clamping plate to clamp the tile. The symmetrical structure ensures balanced force on both sides, while the auxiliary directional slide provides guidance for the clamping plate and prevents swaying during hydraulic cylinder operation. This achieves precise positioning of the tile, ensuring that the tile edge is perpendicular to the spraying trajectory and preventing the spraying edge from shifting due to clamping tilt.

[0019] 2. In this utility model, the moving component adopts a dual-track drive structure with a T-shaped groove and a T-shaped slider. The T-shaped structure has a strong load-bearing capacity and can withstand the weight of the spraying component and the inertial force of movement, which can meet the spraying and moving needs of tiles of different sizes. With the combined use of the hydraulic drive mechanism of the clamping component and the dual-track drive structure of the moving component, the adaptability of the device to tiles of different specifications is improved and the application range of the device is expanded.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0029] like Figure 1-4As shown, this utility model provides a technical solution: an automatic anti-slip coating device for ceramic tiles, including a device base 1, with fixed plates 2 vertically fixed to both sides of the top of the device base 1, and a clamping component 3 that adapts to the size of the ceramic tile is provided between the two fixed plates 2. The clamping component 3 achieves positioning and clamping of ceramic tiles of different specifications through a hydraulic drive mechanism. The device base 1 provides overall support, and the fixed plates 2 provide an installation reference for the clamping component 3 and the moving component 4. The clamping component 3 achieves adaptive positioning of the ceramic tile through hydraulic drive, and the hydraulic system can provide a stable clamping force to ensure that the ceramic tile does not shift during the spraying process.

[0030] The top of the two fixed plates 2 is equipped with a double-track synchronous moving component 4. The top of the moving component 4 is connected to a support frame 5. The top of the support frame 5 is equipped with a first hydraulic cylinder 501. The bottom output end of the first hydraulic cylinder 501 passes through the bottom of the support frame 5 and is connected to a spraying component 6. An industrial-grade PLC controller 7 is set on one side of the support frame 5. The controller 7 has a built-in anti-slip layer spraying process algorithm, which can automatically match the spraying parameters according to the material and size of the tile. The double-track moving component 4 drives the spraying component 6 to move along the length of the tile. The first hydraulic cylinder 501 adjusts the spraying height. The PLC controller 7 integrates algorithms to realize automated control. For materials such as antique tiles and glazed tiles, it can automatically match the spraying pressure and the number of nozzles 602 that are opened.

[0031] The clamping assembly 3 includes two symmetrically arranged clamping plates 301. A second hydraulic cylinder 302 is provided on the outer wall of the two side fixing plates 2, and its output end is fixedly connected to the clamping plate 301. The second hydraulic cylinder 302 drives the clamping plate 301 to clamp the tile. The symmetrical structure ensures that the force on both sides is balanced, which can adapt to tiles of different thicknesses and avoid tile displacement or breakage due to insufficient clamping force or excessive tightness. Auxiliary directional slide rods 303 are provided on both sides of the fixing plate 2 and on the front and back of the second hydraulic cylinder 302. One end of the slide rod is fixedly connected to the clamping plate 301. The auxiliary directional slide rods 303 provide guidance for the clamping plate 301, prevent swaying when the hydraulic cylinder is driven, ensure that the edge of the tile is perpendicular to the spraying trajectory, and avoid the spraying edge displacement due to clamping tilt.

[0032] The inner surface of the clamping plate 301 is provided with a rubber protective pad and a pressure sensor is installed inside. An ultrasonic edge detection sensor 3011 is installed at one end of the front. The rubber protective pad prevents the tile surface from being scratched during clamping. The pressure sensor monitors the clamping force and feeds it back to the PLC controller 7, and the ultrasonic sensor detects the edge position of the tile.

[0033] The movable component 4 includes a movable mounting base 401 fixed on the fixed plate 2, with a T-shaped groove 402 inside. A T-shaped slider 403 is slidably connected in the T-shaped groove 402. A lead screw 4021 is provided on one side of the T-shaped groove 402, and a linear guide 4022 is provided on the other side. The T-shaped groove 402 and the T-shaped slider 403 cooperate to provide a stable moving track. The lead screw 4021 and the linear guide 4022 form a double-track drive structure. The T-shaped structure has a strong load-bearing capacity and can withstand the weight of the spraying component 6 and the inertial force of movement. The lead screw 4021 is threadedly connected to the T-shaped slider 403, and the linear guide 4022 is slidably connected to the other T-shaped slider 403. A drive motor 404 is provided on the back of the movable mounting base 401. The drive motor 404 drives the T-shaped slider 403 on one side to move through the lead screw 4021, and the linear guide 4022 guides the T-shaped slider 403 on the other side to move synchronously, so as to realize the position movement of the spraying component 6.

[0034] The spraying assembly 6 includes a spraying bracket 601 connected to a first hydraulic cylinder 501, with multiple nozzles 602 at the bottom and electromagnetic control valves 6021 on each nozzle 602. The top is connected to an external material supply mechanism via a hose 603. The first hydraulic cylinder 501 adjusts the height of the spraying bracket 601, and the nozzles 602 are controlled by the electromagnetic control valves 6021. The hose 603 delivers paint to the pressure equalization chamber inside the spraying bracket 601. A laser rangefinder sensor 8 is installed on the front of the spraying bracket 601 to measure the distance between the spraying bracket 601 and the tile surface in real time and feeds the data back to the PLC controller 7 to adjust the height of the first hydraulic cylinder 501, ensuring a constant spraying distance and avoiding uneven coating thickness due to height fluctuations.

[0035] The working process of this utility model is as follows: When using an automatic anti-slip coating device for ceramic tiles, firstly, the ceramic tile to be coated is placed on the device base 1, with both sides of the tile parallel to the fixing plate 2. At this time, the clamping assembly 3 is in its initial open state, providing space for the tile. The ultrasonic edge detection sensor 3011 on the front of the clamping plate 301 is activated to detect the edge position of the tile. Simultaneously, the PLC controller 7 begins to collect the size information of the tile, including length, width, and other data. Based on the collected tile size and material information, the PLC controller 7 sends a command to the second hydraulic cylinder 302, which drives the clamping plate 301 to move towards the tile. The symmetrical clamping plates 301 gradually clamp the tile. During the clamping process, the rubber protective pad on the inner surface of the clamping plate 301 contacts the tile surface to prevent the tile from being scratched. At the same time, the pressure sensor monitors the clamping force in real time and feeds the data back to the PLC. The controller 7 ensures that the clamping force can stably fix the tile without breaking it due to excessive tightness. The auxiliary directional slide bar 303 provides guidance for the clamping plate 301 during the clamping process, preventing swaying when the hydraulic cylinder is driven, and ensuring that the edge of the tile is perpendicular to the spraying trajectory.

[0036] The PLC controller 7 calculates the appropriate spraying height based on the thickness and material of the tile. After receiving the instruction, the first hydraulic cylinder 501 drives the spraying assembly 6 to move up and down. The distance between the spraying bracket 601 and the tile surface is measured in real time by the laser range sensor 8, and the data is fed back to the PLC controller 7 to adjust the height of the first hydraulic cylinder 501, ensuring a constant spraying distance and laying the foundation for uniform spraying in the future.

[0037] The drive motor 404 starts, and through the lead screw 4021, it drives the T-shaped slider 403 on one side to move within the T-shaped groove 402. At the same time, the linear guide 4022 guides the T-shaped slider 403 on the other side to move synchronously, so as to realize the smooth movement of the spraying component 6 along the length of the tile. During the movement, the anti-slip layer spraying process algorithm built into the PLC controller 7 automatically matches the spraying parameters, such as the spraying pressure and the number of nozzles 602 opening, according to the material and size of the tile. For example, for different materials such as antique tiles and glazed tiles, the corresponding parameters will be automatically adjusted to ensure the spraying effect.

[0038] During the movement of the spraying assembly 6, the electromagnetic control valve 6021 on the nozzle 602 opens or closes according to the instructions of the PLC controller 7. The paint is transported from the external feeding mechanism to the pressure equalization chamber inside the spraying bracket 601 through the hose 603, and then evenly sprayed out from the opened nozzle 602 to form an anti-slip layer on the tile surface. The laser range sensor 8 continuously monitors the distance between the spraying bracket 601 and the tile surface to ensure that the spraying distance is always kept at the set value, so as to avoid uneven coating thickness due to height fluctuations.

[0039] After the spraying operation is completed, the spraying component 6 returns to its initial position under the drive of the dual-rail moving component 4. The first hydraulic cylinder 501 adjusts the spraying bracket 601 to its initial height, the clamping component 3 returns to the open state, and all components of the device are reset, preparing for the next tile anti-slip layer spraying operation.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
