Description

Technical Field

[0001] This invention relates to the field of building decoration equipment, and in particular to a tile gap filling device. Background Technology

[0002] With the continuous development of the building decoration industry, ceramic tiles are widely used for indoor and outdoor wall and floor tiling due to their advantages such as beauty, wear resistance, and ease of cleaning. After the tiles are laid, a certain width of gap (usually 1-5mm) is left between adjacent tiles to release thermal expansion and contraction stress and improve the overall decorative effect. To prevent stains from seeping in, mold from growing, and to enhance the aesthetics, the tile gaps need to be sealed, a process known as "grout sealing".

[0003] Currently, conventional grout sealing installation mainly uses manual methods: First, grout cleaning tools (such as grout cleaning cones, angle grinders, etc.) are used to manually remove cement mortar residue from the gaps; then, masking tape or anti-fouling wax is applied to both sides of the gaps to prevent grout from overflowing and contaminating the tile surface; next, grout is injected into the gaps using a caulking gun; finally, a grout ball or scraper is used to compact and trim the grout, and after it has cured, the masking tape is removed or any remaining adhesive is cleaned. This process has the following significant drawbacks: The process is complicated and inefficient: multiple steps such as cleaning the joints, applying paper (or wax), injecting glue, pressing the edges, and cleaning need to be completed in separate steps. Operators need to squat and stand up repeatedly and change tools, resulting in high labor intensity and a limited daily construction area per person. Construction quality depends on manual experience: problems such as inconsistent cleaning depth, uneven glue application, and uneven edge pressing frequently occur, which can easily lead to the grout falling off, sinking, or overflowing, affecting the final decorative effect.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Example 1 See Figures 1 to 10 The present invention provides a tile gap filling device, including a vehicle body 1 that moves along the tile gap, a guide wheel 2 rotatably disposed in the middle of the vehicle body 1 for guiding the vehicle body 1 to move along the tile gap, an axle 3 rotatably disposed in the rear of the vehicle body 1, a driving wheel 4 fixedly disposed at both ends of the axle 3, and a handle provided on the vehicle body 1 for the user to hold and push the vehicle body 1 to move. The front end of the vehicle body 1 is equipped with a grouting mechanism 5 for cleaning cement mortar residue in the tile gaps, and the rear end of the vehicle body 1 is equipped with a filling mechanism 6 for filling the tile gaps with sealant and pressing and smoothing the filled sealant.

[0030] When in use, the operator holds the handle and aligns the device with the tile gap to be treated, so that the front opening mechanism 5 is inserted into the gap; then push the vehicle body 1 forward, and the vehicle body 1 moves along the gap with the support of the traveling wheels 4. The guide wheel 2 in the middle fits against the tile surface and automatically guides the vehicle body 1 to move along the center line of the gap, ensuring the stability of the working path. During the movement, the front-end grouting mechanism 5 simultaneously breaks up the cement mortar residue in the tile gaps, completing the grout cleaning operation. The filling mechanism 6 located at the rear of the vehicle body 1 injects the grout sealant into the cleaned gaps, and compacts and smooths the surface, making the grout sealant flush with the tile surface and with smooth edges. The entire process only requires one push operation to continuously complete the three processes of grout cleaning, sealant injection, and edge pressing and leveling.

[0031] By integrating the three major processes of cleaning joints, injecting adhesive, and pressing and smoothing the edges into the same machine, the operator can complete all operations with just one push, avoiding the multi-step repetitive work of "first squatting down to clean joints - then injecting adhesive - finally smoothing" in the traditional process, thus improving construction efficiency.

[0032] The slit opening mechanism 5 includes a motor 7 fixedly installed in the middle of the vehicle body 1. A drive wheel 8 is coaxially fixedly mounted on the motor shaft of the motor 7. An intermediate shaft 9 is rotatably mounted at the front end of the vehicle body 1. A driven wheel 10 connected to the drive wheel 8 via a transmission belt is fixedly mounted at one end of the intermediate shaft 9. A swing arm 11 is also rotatably mounted on the vehicle body 1. Its rotation axis is coaxial with the intermediate shaft 9. A cutting blade 12 and a driven gear 13 are rotatably mounted on both sides of the movable end of the swing arm 11, and the cutting blade 12 and the driven gear 13 are fixed coaxially. A drive gear 14 is also fixedly mounted on the intermediate shaft 9, and the driven gear 13 meshes with the drive gear 14; An adjustment unit 15 for controlling the position of the swing arm 11 is located at the front end of the vehicle body 1.

[0033] In use, the operator first swings the swing arm 11 downwards using the adjustment unit 15, lowering the cutting blade 12 to the working position and inserting it into the tile gap; then, the motor 7 is started, which drives the drive wheel 8 on its motor shaft to rotate. The drive wheel 8 drives the driven wheel 10 located at the front of the vehicle body 1 and the intermediate shaft 9 fixed thereto to rotate synchronously via a transmission belt; the drive gear 14 on the intermediate shaft 9 rotates accordingly and meshes with the driven gear 13 fixed to the same axis as the cutting blade 12, thereby driving the cutting blade 12 to rotate at high speed; as the vehicle body 1 moves along the tile gap, the rotating cutting blade 12 cuts and cleans the cement mortar residue in the gap; After the operation is completed, the operator operates the adjustment unit 15 again to swing the swing arm 11 upward, raising the cutting blade 12 off the ground and making it higher than the tile surface. This prevents the cutting blade 12 from scratching or colliding with the tile when the equipment moves or turns without load, ensuring that the vehicle body 1 can pass smoothly.

[0034] By adjusting the swing arm 11 up and down by adjusting the unit 15, the cutting blade 12 can be lowered to the working depth during the cleaning operation and raised to a safe height when not in operation, which effectively prevents the blade from hitting the tile surface during equipment transfer or storage and protects the integrity of the decorative surface.

[0035] The adjustment unit 15 includes a mounting base 16 fixedly mounted on the vehicle body 1, a control arm 17 rotatably mounted on the upper end of the mounting base 16, and a locking hook 18 rotatably mounted on the middle part of the control arm 17. A spring 19 is provided at the end of the locking hook 18 away from the mounting base 16. One end of the spring 19 is fixedly connected to the locking hook 18, and the other end is fixedly connected to the control arm 17. The movable end of the control arm 17 is rotatably connected to the connecting rod 20, and the movable end of the connecting rod 20 is rotatably connected to the movable end of the swing arm 11. A limiting block 21 is fixedly provided at the upper end of the mounting base 16, and a stop block 22 is provided at the lower part of the mounting base 16. When the control arm 17 rotates downwards to its lower side and abuts against the stop block 22, the locking hook 18 abuts against the side of the limit block 21 near the control arm 17 to lock the control arm 17 in the lower position, so that the cutting blade 12 is in the working position. When the locking hook 18 is hooked on the other side of the limit block 21, the control arm 17 is locked in the upper position, causing the cutting blade 12 to be raised to a position above the tile surface.

[0036] Before use, the equipment is in a non-operational state. The cutting blade 12 needs to be lifted off the ground to avoid scratching the tiles. At this time, the operator pulls the end of the locking hook 18 away from the spring 19 upwards to overcome the tension of the spring 19 and make the locking hook 18 disengage from the limit block 21. Furthermore, a control handle is provided on the locking hook 18 for easy hand pulling. Then, the control arm 17 is rotated upwards, which drives the connecting rod 20 to move, thereby pushing the swing arm 11 to swing upwards around the intermediate axis 9, raising the cutting blade 12 as a whole to a position higher than the surface of the tile. When the control arm 17 is rotated into position, the locking hook 18 is released. Under the action of the spring 19's restoring force, the locking hook 18 automatically hooks onto the upper side of the limit block 21, locking the control arm 17 in the upper position, thus achieving reliable retraction of the cutting blade 12.

[0037] When starting the grout cleaning operation, the operator pulls the locking hook 18 upward again to disengage it from the limiting block 21, and rotates the control arm 17 downward. This causes the swing arm 11 to swing downward via the connecting rod 20, allowing the cutting blade 12 to descend into the tile grout. When the control arm 17 rotates down to its bottom and contacts the stop block 22 at the bottom of the mounting base 16, the locking hook 18 automatically abuts against the lower side of the limiting block 21 under the action of the spring 19, locking the control arm 17 in the lower position and ensuring that the cutting blade 12 is stably at the working depth. Then, the motor 7 is started, and the vehicle body 1 moves along the grout to complete the grout cleaning operation. The entire switching process requires only one-handed operation of the locking hook 18, without the need for tools, and can quickly and reliably switch between "pass mode" and "working mode".

[0038] A volute 23 is fixedly installed on one side of the vehicle body 1. A fan blade is rotatably installed inside the volute 23, and the fan blade is fixed coaxially with the intermediate shaft 9. The volute 23 is provided with an air outlet, and an air outlet pipe 24 is connected to the air outlet. The air outlet pipe 24 extends to the middle of the vehicle body 1 and faces the tile gap.

[0039] During equipment operation, when motor 7 starts, power is transmitted to intermediate shaft 9 via drive wheel 8, transmission belt, and driven wheel 10, causing intermediate shaft 9 to rotate, thereby driving the fan blades to rotate synchronously. This creates negative pressure and generates directional airflow within volute 23. This airflow enters air outlet 24 through the outlet of volute 23 and is blown towards the tile grout area from the outlet end of air outlet 24. When cutting blade 12 cuts and cleans the cement mortar residue in the grout, the resulting dust and fine debris are immediately blown away from the grout by the airflow from air outlet 24, preventing them from falling back into or adhering to the sidewalls of the grout. The entire grout cleaning and dust blowing process is completed simultaneously, ensuring the grout is clean and providing a good base for subsequent grout filling.

[0040] The filling mechanism 6 includes a frame 25 fixedly mounted on the vehicle body 1. The frame 25 is placed at an angle. A glue holder 26 for holding the grout tube 27 is installed on the frame 25. One end of the glue holder 26 is provided with an application unit 28 for filling the grout into the tile gaps, and the other end is provided with a drive unit 29 for pushing the glue inside the grout tube 27.

[0041] In use, first place the tube containing the grout into the adhesive holder 26, aligning the dispensing end of the tube with the application unit 28; then align the front of the device with the cleaned tile grout, and the operator holds the handle and pushes the vehicle 1 forward at a constant speed along the grout; as the vehicle 1 moves, the drive unit 29 is pushed forward by the piston inside the tube, causing the grout to be squeezed out from the front of the tube and evenly injected into the tile grout through the application unit 28. The entire filling process is completed synchronously with the movement of the device, without the need to stop the injection, achieving continuous and efficient grouting operations.

[0042] The drive unit 29 includes a housing 30 fixedly mounted on the rubber bracket 26, a worm gear 31 rotatably disposed inside the housing 30, and a worm wheel 32 rotatably disposed inside the housing 30 and meshing with the worm gear 31. The worm gear 32 has an internal thread at its center and is threadedly connected to a screw 33. One end of the screw 33 near the application unit 28 is fixedly provided with a piston 34 for pushing the adhesive inside the sealant tube 27, and the other end extends to the outer shell 30 and is fixedly provided with a knob. An output pulley 35 is fixedly installed at one end of the worm gear 31, and an input pulley 36 is also fixedly installed on the axle 3. The input pulley 36 and the output pulley 35 are connected by a belt 37.

[0043] First, insert the grout tube 27 into the grout holder 26 and align the front end of the tube with the application unit 28. Then, align the device with the cleaned tile grout. The operator holds the handle and pushes the vehicle body 1 forward at a constant speed. As the vehicle body 1 moves, the axle 3 rotates synchronously with the traveling wheel 4, causing the input pulley 36 fixed on it to rotate. The input pulley 36 transmits power to the output pulley 35 fixed to the end of the worm gear 31 through the belt 37, thereby driving the worm gear 31 to rotate inside the housing. The worm 31 meshes with the worm wheel 32, transmitting rotational motion to the worm wheel 32. Since the worm wheel 32 has an internal thread that engages with the screw 33, the rotation of the worm wheel 32 is converted into the linear pushing motion of the screw 33. The piston 34 at the front end of the screw 33 moves toward the application unit 28, continuously pushing the adhesive in the grout tube 27, so that the grout is stably and continuously squeezed out from the tube outlet and injected into the tile gaps through the application unit 28. If manual adjustment or pre-installation of the adhesive tube is required, the operator can directly rotate the knob on the outside of the outer casing 30 to drive the screw 33 to move in the opposite direction or slightly, thereby achieving precise control of the position of the piston 34.

[0044] The application unit 28 includes an extrusion tube 38 fixedly mounted on the adhesive holder 26. The front end of the extrusion tube 38 is detachably provided with an extrusion head 39. The extrusion head 39 is provided with a pressing plate 40 for pressing and smoothing the grout in the tile gap. A drive wheel 41 is rotatably mounted on the tube body of the extrusion tube 38. A first pulley 42 is mounted on one side of the drive wheel 41. An intermediate rod is also rotatably mounted on the tube body of the extrusion tube 38. A second pulley 43 and a third pulley 44 are mounted on both ends of the intermediate rod, respectively. An auger 45 is rotatably installed inside the extrusion tube 38. A driven bevel gear 46 is fixedly installed at the end of the auger 45 away from the extrusion head 39. A driving bevel gear 47 is rotatably installed on the tube body of the extrusion tube 38. A fourth pulley 48 is fixedly installed on one side of the driving bevel gear 47. The first pulley 42, the second pulley 43, the third pulley 44, and the fourth pulley 48 are connected by a timing belt 49.

[0045] When the equipment is working, the operator aligns the front end of the equipment with the cleaned tile grout, so that the drive wheel 41 at the front end of the coating unit 28 is embedded in the tile grout. Then, the vehicle body 1 is pushed forward, and the drive wheel 41 rolls at the bottom of the grout. On the one hand, it automatically guides and positions itself along the center of the grout, ensuring that the entire machine's trajectory is strictly aligned with the grout. On the other hand, its rotational motion is transmitted through the first pulley 42 and the synchronous belt 49 to the second pulley 43 on the intermediate rod. The intermediate rod rotates synchronously and drives the fourth pulley 48 through the third pulley 44 and the synchronous belt 49 at its other end, thereby driving the active bevel gear 47 to rotate. The active bevel gear 47 meshes with the driven bevel gear 46 at the end of the auger 45, transmitting power to the auger 45 inside the extrusion tube 38, causing the auger 45 to rotate continuously, pushing the sealant from the tube to the extrusion head 39 and injecting it into the gap; at the same time, the pressing plate 40 fixed on the extrusion head 39 follows the extrusion position, pressing the edges and smoothing the surface of the newly filled sealant; throughout the process, the drive wheel 41 serves as both a walking guide and a power input source, improving the automation level of the whole machine.

[0046] The vehicle body 1 is also provided with a waxing mechanism 50. The waxing mechanism 50 includes a control rod 51 rotatably mounted on the vehicle body 1. The rotation axis of the control rod 51 is concentric with the axle 3. Two waxing rollers 52 are rotatably mounted at the movable end of the control rod 51. The outer surface of the waxing rollers 52 is a wax layer. A connecting gear 53 is rotatably installed at each end of the control lever 51. One connecting gear 53 is fixed coaxially with the axle 3, and the other is fixed coaxially with the wax roller 52. Two intermediate gears 54 are also provided between the two connecting gears 53. The two intermediate gears 54 mesh with each other and with an adjacent connecting gear 53.

[0047] Before performing the grouting operation, the operator first aligns the equipment with the tile grout to be treated; when the vehicle body 1 is pushed forward, the axle 3 rotates synchronously with the traveling wheel 4, driving the connecting gear 53 fixed on the same axis to rotate; this power is transmitted to the connecting gear 53 on the other side through two meshing intermediate gears 54, which in turn drives the wax brush roller 52 fixed on the same axis to rotate. Two wax rollers 52 first contact the tile surface during the movement of the equipment. The wax layer on their outer surface is evenly applied to the tile surface on both sides of the tile gap under the action of rotation and friction, forming a thin and continuous isolation wax film. Subsequently, the filling mechanism 6 at the rear of the equipment injects the grout into the gap. Even if a small amount of grout overflows onto the tile surface, it will not adhere due to the isolation effect of the wax film. There is no need to apply masking tape before construction, and it is easy to remove excess grout after construction.

[0048] The wax roller 52 rotates under gear transmission. The linear velocity of its contact part with the tile is opposite to the direction of travel of the vehicle body 1, thereby generating reverse friction on the tile surface during travel, so that the wax layer is evenly spread and firmly adhered.

[0049] Furthermore, a pressure applicator is installed between the vehicle body 1 and the control lever 51. The pressure applicator includes an inner rod and an outer tube. One end of the inner rod is rotatably connected to the vehicle body 1, and the outer tube is fitted onto the lower part of the inner rod and rotatably connected to the middle part of the control lever 51. A compression spring is fitted between the inner rod and the outer tube. One end of the compression spring abuts against the limiting step of the inner rod, and the other end abuts against the inner shoulder of the outer tube, ensuring that the wax roller 52 is always in close contact with the surface of the tile.

[0050] When using this invention, the operator holds the handle and aligns the device with the tile gap to be treated, so that the front opening mechanism 5 is inserted into the gap; then the vehicle body 1 is pushed forward, and the vehicle body 1 moves along the gap with the support of the traveling wheels 4. The guide wheel 2 in the middle is in contact with the tile surface and automatically guides the vehicle body 1 to move along the center line of the gap, ensuring the stability of the working path. During the movement, the front-end grouting mechanism 5 simultaneously breaks up the cement mortar residue in the tile gaps, completing the grout cleaning operation. The filling mechanism 6 located at the rear of the vehicle body 1 injects the grout sealant into the cleaned gaps, and compacts and smooths the surface, making the grout sealant flush with the tile surface and with smooth edges. The entire process only requires one push operation to continuously complete the three processes of grout cleaning, sealant injection, and edge pressing and leveling.

[0051] By integrating the three major processes of cleaning joints, injecting adhesive, and pressing and smoothing the edges into the same machine, the operator can complete all operations with just one push, avoiding the multi-step repetitive work of "first squatting down to clean joints - then injecting adhesive - finally smoothing" in the traditional process, thus improving construction efficiency.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
