[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] This embodiment discloses a self-propelled floor seam caulking machine, as Figure 1 shown, mainly composed of a caulking component 1, a driving component 2, a transmission component 3, and a moving component 4. The driving component 2 is used to provide the original driving force to the transmission component 3. A part of the transmission force of the transmission component 3 is used for the moving component 4 to move along the ground, and another part of the transmission force is used for the caulking component 1 to achieve automatic caulking. The structures of the above components will be described one by one with reference to the respective drawings below.

[0036] As Figure 1 , Figure 4 , Figure 5 shown, the moving component 4 includes a bottom plate 41. The middle parts of the front end and the rear end of the bottom plate 41 respectively extend outward to form convex parts. A front wheel axle 46 is installed on the front convex part, and a rear wheel axle 45 is installed on the rear convex part. Front wheels 42 are respectively installed at both ends of the front wheel axle 46, and rear wheels 43 are respectively installed at both ends of the rear wheel axle 45. A glue outlet hole 47 penetrating the thickness direction is opened in the middle of the bottom plate 41 near the rear wheel end. A glue scraping plate 49 is installed at the bottom of the bottom plate 41 behind the glue outlet hole 47. A guide pin 48 is installed at the bottom of the front convex part of the bottom plate 41. The guide pin 48 is fixed to the bottom of the front convex part in a detachable manner. For example, a threaded hole is opened on the bottom surface of the front convex part, and an external thread is provided on the outer wall of the guide pin 48, and it is assembled by a threaded connection method. The upper part of the guide pin 48 is cylindrical, and the lower part is conical. The guide pin 48 is used to insert into the floor seam to play a guiding role during the moving process. In order to form a better guiding effect and remove certain impurities in the floor seam, the guide pin 48 is preferably selected to have a size equivalent to the width of the floor seam.

[0037] Further optimize the moving component 4. Considering that the caulking plate 49 may scrape the floor joint glue onto the floor tiles on both sides of the floor joint, in order to timely remove the floor joint glue on the floor tile surface, in this embodiment, raw tape 44 is wound around each front wheel 42. One end of the raw tape 44 is fixed to the front wheel 42, and a length of the other end of the raw tape 44 is pulled out and wound and fixed to the rear wheel 43. When the bottom plate 41 moves, the raw tape 44 wound around the front wheel 42 is continuously wound onto the rear wheel 43, and the sticky property of the raw tape 44 is used to remove the floor joint glue on the floor tile surfaces on both sides of the floor joint. After the caulking is completed, the raw tape 44 can be removed and discarded. In order to ensure a better cleaning effect, the distance between the edges of the raw tape 44 wound on the two front wheels 42 on the opposite sides (i.e., the inner sides) should be exactly the same as the width of the floor joint.

[0038] As Figure 2 , Figure 3 , Figure 9 , Figure 10 shown, the caulking component 1 is mainly composed of a support component 11, a rubber tube caulking component 12, and a rubber cylinder 13. Among them, the support component 11 includes a slender support rod 111 and a support 112. The support 112 is fixed to the top of the support rod 111, and the bottom of the support rod 111 is fixed to the bottom plate 41. The support 112 is semi-circular arc-shaped, and the cylindrical barrel of the rubber cylinder 13 is supported and fixed by the support 112. Considering the convenience of observing the stock of the floor joint glue in the rubber cylinder 13 and also for the convenience of filling the rubber cylinder 13 with glue, in this embodiment, an open end 136 is formed on one side of the barrel of the rubber cylinder 13. To prevent the floor joint glue inside the rubber cylinder 13 from flowing out from the open end 136, the rubber cylinder 13 is installed obliquely relative to the top surface of the bottom plate 41 by using the support component 11.

[0039] Further illustrate the structure of the rubber cylinder 13. As Figure 3 shown, the barrel of the rubber cylinder 13 is divided into an upper barrel 131, a middle barrel 132, and a lower barrel 133. The upper barrel 131 is a cylindrical barrel, the middle barrel 132 is a semi-circular arc structure with one side open, and the support 112 supports the middle barrel 132. The lower barrel 133 is a conical barrel with an open bottom. When the rubber cylinder 13 is installed, the lower barrel 133 is inserted into the glue outlet hole 47 on the bottom plate 41. Connecting rods 135 are provided between the upper barrel 131 and the lower barrel 133 on both sides of the middle barrel 132, and the gap between the connecting rods 135 and the edge of the middle barrel 132 forms a sliding groove 134.

[0040] The rubber tube caulking component 12 is as Figure 9 and Figure 10As shown in the figure, it mainly consists of a reset pull bar 121, a slider 122, a rubber pressing plate 123, a force transmission pull bar 124, and a pull bar box 125. Among them, the pull bar box 125 is a rectangular box body with an open bottom. The inside of the pull bar box 125 is used to store the reset pull bar 121 wound into a disc shape. The reset pull bar 121 is similar to the structure of a steel tape measure. One end of it is fixed inside the pull bar box 125, and the other end extends out from the open bottom of the pull bar box 125 and is fixedly connected to the top of the slider 122. The slider 122 is embedded in the sliding groove 134 and can slide up and down along the sliding groove 134. The rubber pressing plate 123 is a sheet-shaped circular plate. Two sliders 122 are symmetrically fixed at both ends of the rubber pressing plate 123. The bottom of each slider 122 is fixedly connected to one end of the force transmission pull bar 124.

[0041] As Figure 4 , Figure 6 , Figure 7 , Figure 8 shown, the drive assembly 2 includes a motor 21, a motor force transmission rod 22, and a motor force transmission belt 23. The motor 21 is installed on the bottom plate 41. One end of the motor force transmission rod 22 is connected to the motor output shaft, and the other end of the motor force transmission rod 22 is connected to the motor force transmission belt 23. The transmission assembly 3 includes two driving gears 33 located above the two front wheels 42. The two driving gears 33 are connected by a gear force transmission rod 31. The other end of the motor force transmission belt 23 is connected to the gear force transmission rod 31. The front wheel axle 46 and the gear force transmission rod 31 are connected by a wheel force transmission belt 32. A support plate 35 is provided on the top of the front convex part of the bottom plate 41. An arc-shaped groove is formed on the top of the support plate 35, and the surface of the groove is smooth. The gear force transmission rod 31 is supported by the groove. On both sides of the glue outlet hole 47 on the bottom plate 41, there are driven gear sets 36 respectively. The driven gear sets 36 are connected to the driving gears 33 by gear chains 34.

[0042] Among them, the structure of the driven gear set 36 is as Figure 7 and Figure 8As shown in the figure, it mainly includes an external gear 361, an internal gear 362, an internal gear shaft 363, a tray 365 and a return spring 364. The inner ring of the external gear 361 is hollow, and the inner wall is provided with teeth that match the teeth on the outer ring of the internal gear 362. The purpose is that when the internal gear 362 is inserted into the inner ring of the external gear 361, the two gears can mesh with each other, and the internal gear 362 can rotate synchronously with the external gear 361. If the internal gear 362 is pushed, it can be disengaged from the inner ring of the external gear 361, separating the two. The outer ring of the internal gear 362 has teeth. The middle part of the internal gear 362 is fixed to one end of the internal gear shaft 363. The other end of the internal gear shaft 363 is fixedly connected to the middle part of the circular tray 365. A return spring 364 is sleeved on the internal gear shaft 363 between the internal gear 362 and the tray 365. One end of the return spring 364 is fixed on the tray 365, and the other end of the return spring 364 is fixed on the internal gear 362. The internal gear shaft 363 outside the tray 365 is fixedly connected to the bottom end of the force transmission pull bar 124. A pressing opening is provided on the outer shell covering the gear chain 34 at the position corresponding to the driven gear set 36, so that the internal gear 362 can be exposed in the pressing opening for convenient alignment of the pressing force application. The tray 365 is located outside the other end of the outer shell, playing a limiting role.

[0043] When using the sealant applicator designed by the present utility model, first determine the sealant application position and the width of the floor joint. Select a guiding needle 48 adapted to the width of the floor joint and install it on the bottom plate 41. Then, sleeved the raw tape 44 on the two front wheels 42 and adjust the positions of the raw tapes 44 on the two front wheels 42 so that the distance between the two raw tapes 44 is exactly the same as the width of the floor joint. Pour the floor joint sealant into the glue cylinder 13. At this time, the pressure plate 123 is at the original position above the glue cylinder 13. After preparation, place the sealant applicator at the floor joint sealant application position and insert the guiding needle 48 into the floor joint. Start the motor 21. The output shaft of the motor drives the motor force transmission rod 22 to rotate. The motor force transmission rod 22 drives the motor force transmission belt 23 to rotate. The motor force transmission belt 23 drives the gear force transmission rod 31 to rotate. The gear force transmission rod 31 drives the front wheel axle 46 to rotate through the wheel force transmission belt 32. The front wheel axle 46 drives the front wheels 42 to rotate, so that the sealant applicator can move along the floor joint. At the same time, the gear force transmission rod 31 also drives the driving gear 33 to rotate. The driving gear 33 drives the outer gear 361 of the driven gear set 36 to rotate through the gear chain 34. When the inner gear 362 is engaged with the outer gear 361, the inner gear 362 rotates with the outer gear 361, and the inner gear shaft 363 rotates synchronously with the inner gear 362. The force transmission pull bar 124 can be continuously pulled down and wound around the inner gear shaft 363. The force transmission pull bar 124 will pull the slider 122 to move downward along the chute 134. The slider 122 will drive the pressure plate 123 to squeeze the floor joint sealant in the glue cylinder 13 downward, and continuously inject the floor joint sealant in the glue cylinder 13 into the floor joint through the glue outlet hole 47. During the automatic movement of the sealant applicator, it automatically applies sealant to the floor joint. The scraping plate 49 scrapes the floor joint sealant in the floor joint flat. During the movement of the front wheels 42, the raw tapes 44 connecting the front wheels 42 and the rear wheels 43 will adhere the floor joint sealant on the floor tiles on both sides of the floor joint to the raw tapes 44. The raw tapes 44 continuously come off the front wheels 42 and are wound around the rear wheels 43. After the sealant application is completed, remove the raw tapes 44 from the rear wheels 43 and throw them away, and clean the scraping plate 49.

[0044] Further explanation, during the movement of the glue machine, if the front wheel 42 collides with an obstacle (such as a wall), in order to avoid the motor 21 from continuing to run and malfunctioning, a sensor (such as a contact position sensor) can be installed at the front end of the bottom plate 41. After the collision, the sensor will feed back the signal to the controller that controls the motor 21, and the controller will issue a stop command to the motor 21. The front wheel 42 will no longer rotate, and the construction personnel will move the glue machine to the next glue application position for glue application. During the movement of the glue machine, if the ground seam glue in the glue cylinder 13 is used up, the glue pressing plate 123 will drop to the bottom of the glue cylinder 13. At this time, it is necessary to prevent the motor 21 from continuing to rotate. Therefore, a sensor can be installed at the bottom of the glue cylinder 13. Once it is detected that the glue pressing plate 123 has dropped to the specified position, it will be fed back to the controller, and the controller will issue a stop command to the motor 21, and the glue machine will stop the glue application work. An alarm can also be set on the glue machine. Once the controller receives the sensor signal fed back due to the exhaustion of the ground seam glue, the controller controls the alarm to emit a prompt sound to remind the construction personnel to fill the glue cylinder 13 with glue in time. During the glue filling operation, since the glue pressing plate 123 is already at the bottom of the glue cylinder 13, in order to reset the glue pressing plate 123 to the original position, it is necessary to push the inner gear 362 with force to disengage the inner gear 362 from the inner ring of the outer gear 361. Driven by the reset spring 364, the force transmission pull bar 124 wound on the inner gear shaft 363 gradually loosens, and when the reset pull bar 121 is pulled upward, the slider 122 moves upward continuously, pulling the glue pressing plate 123 back to its original position, and the pulled reset pull bar 121 is rewound and retracted into the pull box 125. When the glue pressing plate 123 is reset, glue can be poured into the glue cylinder 13. After the glue filling is completed, the front wheel 42 is rotated to drive the gear chain 34 to adjust the relative position of the outer gear 361 and the inner gear 362, so that the inner gear 362 is re-embedded in the inner ring of the outer gear 361 to complete the engagement of the two. At this point, the motor 21 can be restarted to continue the ground seam glue filling operation.
