[0002] With the improvement of people's living standards and the change of aesthetic concepts, tile seam beautification construction has become a trendy topic, constantly attracting more customers to learn more, and has become an indispensable part of home improvement projects. In addition to being waterproof, oil-proof, and anti-bacterial, seam beautification also has a beautification effect that ordinary caulking agents cannot achieve.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0038] In one embodiment of the present invention, see Figures 1 to 10A glue-spraying device for decoration and renovation comprises a mobile trolley 1, a glue-spraying cylinder 22, a rotating material-changing mechanism 57, a hydraulic extrusion mechanism 58, an angle adjustment mechanism 59 and an automatic tracking mechanism 60; a driving motor 3 is rotatably installed at the bottom tail end of the mobile trolley 1, and a driving wheel 2 is installed on the output shaft of the driving motor 3; the middle part of the glue-spraying cylinder 22 is rotatably connected to the front end of the mobile trolley 1, a nozzle 23 is installed at the front end of the glue-spraying cylinder 22, a first top block 25 is slidably connected inside the glue-spraying cylinder 22, a mounting frame 28 is fixedly connected to the outer wall of the glue-spraying cylinder 22, and the inner diameter of the glue-spraying cylinder 22 is the same as that of the rubber hose; a one-way valve 38 is installed on the side of the outer wall of the glue-spraying cylinder 22 close to the nozzle 23, and the material discharge of the one-way valve 38 The end faces the inside of the glue barrel 22, the feeding end of the one-way valve 38 is fixedly connected to the fixed barrel 39, the fixed barrel 39 is fixedly connected with a positioning barrel 41, the positioning insert barrel 40 is slidably connected to the positioning barrel 41, the positioning insert barrel 40 is connected to the valve core of the one-way valve 38, the positioning barrel 41 and the fixed barrel 39 are outerly provided with a third spring 42, the positioning insert barrel 40 and the glue outlet of the hose cooperate with each other; the rotary material changing mechanism 57 is installed between the mounting frame 28 and the glue barrel 22; the hydraulic extrusion mechanism 58 is installed on the mounting frame 28 and the glue barrel 22; the angle adjustment mechanism 59 is installed between the mobile trolley 1 and the glue barrel 22; the automatic tracking mechanism 60 is installed at the front end of the mobile trolley 1;

[0039] The present invention firstly carries out simultaneous loading of multiple groups of rubber hoses by means of the rotating material changing mechanism 57, and adjusts the angle of the rubber tube 22 and the height of the nozzle 23 according to the height of the brick joint by means of the angle adjusting mechanism 59, and at the same time installs the automatic tracking mechanism 60 into the brick joint, and then extrude the rubber hose by means of the hydraulic extrusion mechanism 58, so that the colloid in the rubber hose is extruded into the rubber tube 22, and at the same time, the hydraulic extrusion mechanism 58 controls the first top block 25 to move in the rubber tube 22 in a direction away from the nozzle 23, so that the rubber hose is extruded into the rubber tube 22 through the spatial change caused by the movement of the first top block 25. Part of the colloid in the glue barrel 22 is stored, while the other part is sprayed out along the nozzle 23 for glue application. When the colloid in a group of rubber tubes is extruded, the hydraulic extrusion mechanism 58 automatically resets. During this process, the hydraulic extrusion mechanism 58 controls the first top block 25 to move in the glue barrel 22 toward the nozzle 23, thereby extruding the colloid stored in the glue barrel 22. At this time, the rotary material changer can rotate to rotate and replace the empty rubber tube below the output end of the hydraulic extrusion mechanism 58 with a full rubber tube, and then the above process can be repeated to achieve uninterrupted glue application without stopping the machine.

[0040] During the gluing process of the equipment, the mobile trolley 1 is driven by the driving motor 3 to move at a uniform speed, and automatically moves forward along the direction of the brick joint under the action of the automatic tracking mechanism 60, thereby achieving full-automatic tracking of the brick joint and uniform gluing.

[0041] In one case of this embodiment, see Figure 5 , Fig. 9 and Fig.10 The hydraulic extrusion mechanism 58 includes a first hydraulic cylinder 24, a second hydraulic cylinder 34 and a hydraulic pump 44; the second hydraulic cylinder 34 is installed on the mounting frame 28, and the output shaft of the second hydraulic cylinder 34 is fixedly connected with a second top block 35, and the second top block 35 cooperates with the fixed cylinder 39 to clamp the rubber hose and extrude the rubber hose through the extension of the second top block 35. The first hydraulic cylinder 24 is installed at the tail of the rubber barrel 22, and the output shaft of the first hydraulic cylinder 24 is fixedly connected to the first top block 25. The cylinder volumes of the first hydraulic cylinder 24 and the second hydraulic cylinder 34 are the same, but the inner diameter of the second hydraulic cylinder 34 is twice the square root of the first hydraulic cylinder 24, and the first hydraulic cylinder 24 is close to A first hydraulic oil port 26 is provided at one end of the glue barrel 22, a second hydraulic oil port 27 is provided at one end of the first hydraulic cylinder 24 away from the glue barrel 22, a third hydraulic oil port 36 is provided at one end of the second hydraulic cylinder 34 close to the second top block 35, a fourth hydraulic oil port 37 is provided at one end of the second hydraulic cylinder 34 away from the second top block 35, the hydraulic pump 44 is installed on the mobile trolley 1, a steering valve 45 is installed between the feeding end and the discharging end of the hydraulic pump 44, four groups of fifth hydraulic oil ports 46 are installed on the steering valve 45, and the four groups of fifth hydraulic oil ports 46 are respectively connected to the first hydraulic oil port 26, the second hydraulic oil port 27, the third hydraulic oil port 36, and the fourth hydraulic oil port 37;

[0042] The hydraulic extrusion mechanism 58 pressurizes and pumps the hydraulic oil in the pipeline through the setting of the hydraulic pump 44, and automatically switches and adjusts the flow direction of the hydraulic oil in the first hydraulic oil port 26, the second hydraulic oil port 27, the third hydraulic oil port 36, and the fourth hydraulic oil port 37 through the setting of the steering valve 45. When a group of rubber hoses moves below the second top block 35, the second top block 35 is in a retracted state, while the first top block 25 remains in an extended state. At this time, oil flows into the first hydraulic oil port 26 in the first hydraulic cylinder 24, and oil flows out from the second hydraulic oil port 27. The output shaft of the first hydraulic cylinder 24 enters a retracted state under the push of the hydraulic oil, thereby driving the first top block 25 to move in the direction away from the nozzle 23 in the rubber barrel 22. At the same time, oil flows out from the third hydraulic oil port 36 in the second hydraulic cylinder 34, and oil flows into the fourth hydraulic oil port 37. The output shaft of the second hydraulic cylinder 34 enters an extended state under the push of the hydraulic oil. state, thereby driving the second top block 35 to move in the direction close to the rubber tube, thereby squeezing the rubber tube, and injecting the colloid in the rubber tube into the glue barrel 22. At this time, the colloid of the moving part of the first top block 25 will be sucked into the glue barrel 22, and since the cylinder volume of the first hydraulic cylinder 24 and the second hydraulic cylinder 34 are the same, but the stroke of the second hydraulic cylinder 34 is twice that of the first hydraulic cylinder 24, and the time required for a set of reciprocating movements of the first hydraulic cylinder 24 and the second hydraulic cylinder 34 is the same, that is, the moving speed of the second top block 35 is twice that of the first top block 25. At this time, the inflow speed of the colloid entering the glue barrel 22 is twice the speed of the colloid suction when the first top block 25 moves, and the excess colloid will be sprayed out along the nozzle 23, thereby completing the glue application, that is, half of the colloid in the rubber tube is sprayed out along the nozzle 23, and the other half is stored in the glue barrel 22 under the suction of the first top block 25;

[0043] After that, when the colloid in the rubber hose is squeezed out, the second hydraulic cylinder 34 cannot continue to extend and the first hydraulic cylinder 24 cannot continue to contract, the steering valve 45 turns and controls the flow direction of the hydraulic oil in the first hydraulic oil port 26, the second hydraulic oil port 27, the third hydraulic oil port 36, and the fourth hydraulic oil port 37 to change. At this time, the first hydraulic oil port 26 in the first hydraulic cylinder 24 discharges oil and the second hydraulic oil port 27 enters oil. The output shaft of the first hydraulic cylinder 24 enters the extended state under the push of the hydraulic oil, thereby pushing the first top block 25 to move in the direction close to the nozzle 23, thereby squeezing the colloid in the rubber barrel 22, and because the first top block The moving speed of the second top block 25 is half of that of the second top block 35, so the glue discharging speed at the nozzle 23 remains unchanged. At the same time, the third hydraulic oil port 36 in the second hydraulic cylinder 34 is supplied with oil, and the fourth hydraulic oil port 37 is supplied with oil. The output shaft of the second hydraulic cylinder 34 enters a contracted state under the push of the hydraulic oil, thereby driving the second top block 35 to move and reset. When the second top block 35 moves to the top, the second hydraulic cylinder 34 cannot continue to contract and the first hydraulic cylinder 24 cannot continue to extend, and the steering valve 45 turns again. In this process, the empty rubber hose under the second top block 35 is rotated and replaced with a full rubber hose through the rotating material changing mechanism 57.

[0044] By repeating the above process, the colloid can be automatically replenished without stopping the machine, and the staff only needs to remove the empty hose from the rotary material changing mechanism 57 and replenish it with a new hose full of colloid.

[0045] In one case of this embodiment, see Fig. 9 The rotating material changing mechanism 57 includes a rotating rod 29, a rotating frame 30, and a motor 43; the rotating rod 29 is rotatably connected between the mounting frame 28 and the glue barrel 22, the rotating frame 30 is fixedly connected to the rotating frame 30, and a plurality of groups of circumferentially distributed plug-in barrels 31 are fixedly connected to the rotating frame 30, and a spring barrel 32 is slidably connected to the plug-in barrel 31, and a second spring 33 is installed between the spring barrel 32 and the plug-in barrel 31, and the motor 43 is installed on the mounting frame 28, and the output shaft of the motor 43 is connected to the rotating rod 29, and the motor 43 is a stepping motor, and the signal of the stepping motor is sent by the steering valve 45;

[0046] The rotating material changing mechanism 57 elastically lifts the spring cylinder 32 through the setting of the second spring 33, and the spring cylinder 32 lifts the hose, so that the bottom of the hose is higher than the fixed cylinder 39. After that, when the steering valve 45 completes two steering operations, the steering valve 45 sends a pulse signal. After receiving a set of pulse signals, the motor 43 starts and rotates a step. The motor 43 drives the rotating rod 29 to rotate, and the rotating rod 29 drives the rotating frame 30 to rotate. The rotating frame 30 drives the hose to rotate, so that the vacant hose above the fixed cylinder 39 is rotated and replaced. When the new hose rotates to the top of the fixed cylinder 39 After that, the second top block 35 is pressed down again, thereby pressing the hose downward. The pressure on the hose is first transmitted to the second spring 33, thereby compressing the second spring 33, and the spring tube 32 slides into the insertion tube 31. At the same time, the hose is pressed down synchronously, so that the bottom of the hose is inserted into the positioning insert tube 40, and the positioning insert tube 40 is driven to move into the positioning tube 41 by the pushing of the hose, and the third spring 42 is compressed. At this time, the positioning insert tube 40 drives the valve core of the one-way valve 38 to move, thereby opening the one-way valve 38. At this time, the colloid in the hose is injected into the glue cylinder 22 along the one-way valve 38 under the pushing of the second top block 35.

[0047] In one case of this embodiment, see Figure 2 The angle adjustment mechanism 59 includes a fixed rod 52, a slider 53, a driving arm 54, and a screw 55. The fixed rod 52 is fixedly connected to the base, the slider 53 is slidably installed on the fixed rod 52, one end of the driving arm 54 is rotatably connected to the slider 53, and the other end of the driving arm 54 is rotatably connected to the glue barrel 22. The screw 55 is rotatably connected to the base, the screw 55 is threadedly connected to the slider 53, and a knob 56 is fixedly connected to the screw 55. The angle adjustment mechanism 59 drives the screw 55 to rotate by screwing the knob 56. The screw 55 is threadedly connected to the slider 53 to convert the rotational motion of the screw 55 into the linear motion of the slider 53. The slider 53 drives the driving arm 54 to rotate and lift, and the driving arm 54 drives the glue barrel 22 to rotate and lift, thereby adjusting the pitch angle of the glue barrel 22.

[0048] In one case of this embodiment, see Figure 7 and Figure 8The automatic tracking mechanism 60 includes a front fork 4 fixedly connected to the front end of the mobile vehicle 1, a rotating shaft 5 is rotatably connected in the front fork 4, a steering wheel 6 is fixedly connected to the bottom of the rotating shaft 5, a bogie 16 is fixedly connected to the top of the rotating shaft 5, and a driving rod 17 is connected to the rotating wheel between the bogies 16, a fixed frame 7 is fixedly connected to the front fork 4, a mounting seat 8 is fixedly connected in the fixed frame 7, a rotating cylinder 9 is rotatably connected in the mounting seat 8, a connecting shaft 10 is installed in the rotating cylinder 9, a connecting shaft 10 is fixedly connected to a connecting frame 13 at the bottom of the connecting shaft 10, and a rotating frame 13 is rotatably connected in the connecting frame 13 A disc-shaped clamping knife 14 is connected, a limiting groove 11 is arranged in the inner wall of the rotating cylinder 9, a limiting block 12 is fixedly connected to the outer wall of the connecting shaft 10, the limiting block 12 cooperates with the limiting groove 11, a first spring 15 sleeved on the connecting shaft 10 is arranged between the connecting frame 13 and the mounting seat 8, a handle 21 is fixedly connected to the top of the connecting shaft 10, a guide rod 18 is fixedly connected to the driving rod 17, a rotating arm 19 is fixedly connected to the rotating cylinder 9, an adjusting groove 20 is arranged in the rotating arm 19, and the guide rod 18 is arranged in the adjusting groove 20;

[0049] When the automatic tracking mechanism 60 is in a non-working state, the staff needs to lift the connecting shaft 10 through the handle 21 and rotate it 90 degrees. At this time, the connecting shaft 10 drives the limit block 12 to escape from the limit groove 11, and then rotates 90 degrees driven by the connecting shaft 10, so that the limit block 12 and the limit groove 11 are misaligned with each other. At this time, the limit block 12 does not fall under the obstruction of the rotating cylinder 9. At this time, the disc-shaped clamping knife 14 rises under the drive of the connecting shaft 10 and is higher than the driving wheel 2 and the rotating cylinder 9. The automatic tracking mechanism 60 is used to prevent the disc-shaped card knife 14 from contacting the ground when not in operation, and to prevent the disc-shaped card knife 14 from contacting the hard ground and causing damage to the disc-shaped card knife 14. When the automatic tracking mechanism 60 is used, the staff needs to rotate the handle 21 to make the limit groove 11 and the limit block 12 overlap with each other. At this time, the connecting shaft 10 drives the limit block 12 to be inserted into the limit groove 11 under the elastic push of the first spring 15. At this time, the connecting shaft 10 and the rotating cylinder 9 are in the action of the limit groove 11 and the limit block 12. The disc-shaped clamping knife 14 is axially fixed by the lower part, and the disc-shaped clamping knife 14 is driven by the connecting shaft 10 to descend and is lower than the driving wheel 2 and the steering wheel 6, and then the disc-shaped clamping knife 14 is clamped into the brick joint, and then when the mobile trolley 1 moves, the disc-shaped clamping knife 14 rolls in the brick joint driven by the mobile trolley 1, and when the direction of the brick joint changes, the disc-shaped clamping knife 14 rotates along the direction of the brick joint under the lateral limit of the brick joint, and the disc-shaped clamping knife 14 drives the connecting shaft 10 to rotate, and the disc-shaped clamping knife 14 drives the rotating cylinder 9 to rotate through the limiting groove 11 and the limiting block 12, and the rotating cylinder 9 drives the rotating arm 19 to rotate, and the rotating arm 19 drives the driving rod 17 to move through the mutual cooperation of the adjusting groove 20 and the guide rod 18, and the driving rod 17 drives the bogie 16 to rotate around the rotating shaft 5, and the bogie 16 drives the steering wheel 6 to rotate through the rotating shaft 5, thereby automatically adjusting the forward direction of the mobile trolley 1, and then the mobile trolley 1 automatically tracks the brick joint.
