Description

Technical Field

[0001] This application relates to the field of tire sealant filling, and in particular to an automated tire sealant filling device and filling method thereof. Background Technology

[0002] Tire sealant is a mixture containing various high-molecular chemical materials. It is widely applicable to the rubber tires of various electric vehicles, motorcycles, and small and medium-sized cars. It is particularly effective for tire punctures with a diameter of about 1-5 mm and is an essential item to carry with you. Tire sealant filling refers to the process of filling the tire sealant into a container, which makes it easy to store and convenient to use.

[0003] Currently, the standard procedure for filling tire sealant is as follows: the can is picked up manually one by one, the can opening is aligned with the tire sealant outlet, and the tire sealant is filled into the can to complete the filling.

[0004] However, this operating mode is obviously not only laborious, but also has very low efficiency in filling tire sealant. Summary of the Invention

[0005] In order to improve the problems existing in the above-mentioned technology, this application provides an automated tire repair fluid filling equipment and filling method thereof.

[0006] In a first aspect, this application provides an automated tire sealant filling device, which adopts the following technical solution: An automated tire sealant filling device includes: a workbench with a conveyor belt mechanism, a discharge assembly, and a replenishment assembly. The discharge assembly includes a discharge box, a solenoid valve, and a discharge pipe. The discharge box is mounted on the workbench, the discharge pipe is connected to the discharge box, the solenoid valve is mounted on the discharge pipe, and the replenishment assembly is connected to the discharge box.

[0007] By adopting the above technical solution, multiple tanks are placed sequentially on the conveyor belt mechanism, and the conveyor belt mechanism is controlled to transport the tanks sequentially to the discharge pipe; then the solenoid valve is controlled to open the discharge pipe to fill the tire sealant into the tank; thus, not only is labor-saving, but also during filling, there is no need for manual judgment of the filling progress, thereby improving the filling efficiency of tire sealant.

[0008] Optionally, the fluid replenishment assembly includes: a fluid replenishment tank, a partition, a moving rod, a connecting pipe, a sliding plate, a guide rod, a lead screw, and a handwheel. The fluid replenishment tank is disposed on the worktable, the partition is slidably disposed within the fluid replenishment tank, the guide rod is fixed to the worktable, the sliding plate is slidably sleeved on the guide rod, the lead screw is rotatably mounted on the worktable and passes through the sliding plate and is threadedly engaged, the handwheel is fixedly connected to the lead screw, one end of the moving rod is fixed to the partition and the other end is fixed to the sliding plate, one end of the connecting pipe is connected to the fluid replenishment tank and the other end is connected to the discharge tank.

[0009] By adopting the above technical solution, if the tire sealant in the discharge tank is insufficient, the screw is turned by handwheel to drive the slide plate to move closer to the sealant tank. That is, the moving rod drives the partition to move, so that the partition squeezes the tire sealant into the discharge tank to replenish the discharge tank, thereby ensuring the continuous filling of tire sealant into the tank.

[0010] Optionally, a limit rod is fixedly installed on the worktable.

[0011] By adopting the above technical solution, the limiting rod is used to limit the tank, so that the conveyor belt mechanism can stably transport the tank, making it less likely for the tank to tilt or tip over.

[0012] Optionally, a positioning component is provided on the worktable. The positioning component includes a positioning part, which includes a positioning plate and a pushing cylinder. The pushing cylinder is fixed on the worktable, and the output shaft of the pushing cylinder is fixedly connected to the positioning plate.

[0013] By adopting the above technical solution, during the tank transportation process, the push cylinder is activated to push the positioning plate; then, the tank will contact the positioning plate until the second tank contacts the positioning plate, at which point the conveyor belt mechanism can be stopped, thereby ensuring that the discharge pipe is aligned with the opening of the tank, so as to achieve the effect of not wasting tire sealant.

[0014] Optionally, the positioning assembly further includes a driving part and an extension part. The driving part includes a support rod, a rack, a gear, a drive rod, and a pull rope. The rack is fixed to the positioning plate, the support rod is fixed to the worktable, the drive rod is rotatably mounted on the support rod, the gear is coaxially sleeved on the drive rod, and the rack meshes with the gear. The extension part is disposed inside the discharge pipe, and one end of the pull rope is wound around the drive rod, and the other end is connected to the extension part.

[0015] By adopting the above technical solution, during the transportation of the tank, the push cylinder is activated to move the positioning plate halfway, thus ensuring that the tank can contact the positioning plate and achieve the effect of positioning the tank; during this process, the gear drives the drive rod to rotate, and the drive rod releases the pull rope, thereby extending the part to bring the tank closer.

[0016] Optionally, the extension portion includes: an extension tube, a ring plate, and a pressure spring. The extension tube is disposed inside the discharge pipe. The inner wall of the discharge pipe has a sliding groove, and the inner wall of the sliding groove has an annular groove. One end of the ring plate is disposed in the sliding groove, and the other end is disposed in the annular groove. The ring plate is fixedly connected to the extension tube. The pressure spring is fixed between the ring plate and the inner wall of the annular groove. The end of the pull rope away from the drive rod is fixedly connected to the ring plate.

[0017] By adopting the above technical solution, when the gear drives the drive rod to rotate, the drive rod releases the pull rope, and through the downward pressure of the spring, the ring plate will drive the insertion tube to move downward, thus approaching the tube body; after positioning the two tanks, the push cylinder is activated again to push the positioning plate to move the remaining half distance; during this process, the insertion tube continues to move downward and is inserted into the tank body, so that during filling, the tire sealant will be poured into the tank body through the insertion tube, further ensuring that the tire sealant is completely poured into the tank body, thus reducing the likelihood of waste.

[0018] Optionally, the extension portion further includes a sealing sleeve, which is fixedly fitted onto the annular plate.

[0019] By adopting the above technical solution, the sealing sleeve can improve the sealing performance between the ring plate and the inner wall of the ring groove, thus making it less likely for the tire sealant to leak.

[0020] Optionally, the insertion tube is provided with a splash-proof component, which includes a splash-proof part, a slider, a sleeve, a sealing gasket, and a return spring. The insertion tube has a mounting groove, the slider is slidably disposed in the mounting groove, the sleeve is sleeved on the insertion tube and fixed to the slider, the sealing gasket is fixed to the sleeve, and the return spring is fixed between the slider and the inner wall of the mounting groove.

[0021] By adopting the above technical solution, during the process of the insertion tube extending into the tank, the sealing gasket will come into contact with the top wall of the tank, and the slider will slide upward relative to it, thereby the return spring will press the sealing gasket onto the tank to seal the opening of the tank.

[0022] Optionally, the splash-proof assembly further includes an enlarged section, which includes a pressure rod, a pressure plate, a movable plate, a rubber sleeve, a hose, and a connecting spring. The discharge pipe is provided with a receiving cavity. The pressure plate and the movable plate are both slidably disposed within the receiving cavity. The rubber sleeve is sleeved on the movable plate. The connecting spring is fixed between the pressure plate and the movable plate. One end of the pressure rod is fixed to the pressure plate, and the other end extends through to the outside of the receiving cavity. A water storage cavity is formed on the sealing gasket. One end of the hose communicates with the receiving cavity, and the other end communicates with the water storage cavity.

[0023] By adopting the above technical solution, during the downward movement of the ring plate, the ring plate contacts the pressure rod and presses down on the pressure rod. The pressure rod will push the pressure plate and the moving plate downward, thereby squeezing the water in the accommodating cavity into the water storage cavity to increase the volume of the sealing gasket. After the sealing gasket comes into contact with the tank body, the sealing gasket will expand in all directions, thereby adapting to the opening size of different tanks and improving applicability.

[0024] Secondly, this application provides a filling method for an automated tire sealant filling device, employing the following technical solution: A filling method for an automated tire sealant filling device includes the following steps: S1: Multiple tanks are placed sequentially on the conveyor belt mechanism and transported by the conveyor belt mechanism; S2: Whenever the tank is transported to the bottom of the discharge pipe, the tank is positioned using a positioning plate to ensure that the discharge pipe is aligned with the opening of the tank; S3: Control the solenoid valve to open the discharge pipe to fill the tire sealant into the tank.

[0025] By adopting the above technical solution, tire repair fluid can be filled quickly.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. Not only does it save labor, but it also eliminates the need for manual monitoring of the filling progress, thereby improving the filling efficiency of tire sealant.

[0027] 2. If the tire sealant in the discharge tank is insufficient, turn the screw by handwheel to drive the slide plate closer to the sealant tank. This moves the baffle plate, which then squeezes the sealant into the discharge tank to replenish it, thus ensuring continuous filling of the tank with sealant.

[0028] 3. The limit rod is used to limit the tank, so that the conveyor belt mechanism can transport the tank stably, making it less likely for the tank to tilt or tip over. Attached Figure Description

[0031] This application provides an automated tire repair fluid filling device.

[0032] Example 1: See Figure 1 An automated tire sealant filling device includes: a workbench 1, on which a conveyor belt mechanism 11 is provided. In this embodiment, the conveyor belt mechanism 11 is a commercially available conventional conveyor belt mechanism 11 used for transporting the tank. A discharge assembly 2 is provided on the workbench 1. In this embodiment, the discharge assembly 2 has two sets, and the discharge assembly 2 is used to fill the tire sealant into the tank.

[0033] See Figure 1 The discharge assembly 2 includes a discharge box 21, a solenoid valve 22, and a discharge pipe 23. The discharge box 21 is fixed on the workbench 1 and is located directly above the conveyor belt mechanism 11. The discharge pipe 23 is connected to the discharge box 21. The solenoid valve 22 is installed on the discharge pipe 23 to control the opening or closing of the discharge pipe 23. In this embodiment, both the solenoid valve 22 and the conveyor belt mechanism 11 are controlled by a PLC controller. During filling, multiple cans are placed sequentially on the conveyor belt mechanism 11, and the conveyor belt mechanism 11 is controlled to transport the cans sequentially to the discharge pipe 23. Then, the solenoid valve 22 is controlled to open the discharge pipe 23 to fill the cans with tire sealant. When the cans are full, the control valve closes the discharge pipe 23 to stop filling, and the conveyor belt mechanism 11 transports the next can to the discharge pipe 23 again. This not only saves labor but also eliminates the need for manual judgment of the filling progress, thereby improving the filling efficiency of tire sealant.

[0034] See Figure 1 , Figure 2 and Figure 3 Furthermore, a fluid replenishment assembly 3 is provided on the workbench 1. The fluid replenishment assembly 3 includes: a fluid replenishment tank 31, a partition 32, a moving rod 33, a connecting pipe 34, a sliding plate 35, a guide rod 36, a lead screw 37, and a handwheel 38. The fluid replenishment tank 31 is fixed on the workbench 1 and has a replenishment inlet for replenishing tire sealant into the fluid replenishment tank 31. The partition 32 is slidably disposed inside the fluid replenishment tank 31 and slides horizontally. The partition 32 is used to divide the interior of the fluid replenishment tank 31 into two cavities. In this embodiment, a sealing sleeve can be fitted on the partition 32 to improve the sealing between the partition 32 and the fluid replenishment tank 31.

[0035] See Figure 1 The lead screw 37 is rotatably mounted on the worktable 1 and is horizontally positioned. The lead screw 37 passes through the slide plate 35 and is threadedly engaged with the slide plate 35. The guide rod 36 is fixed to the worktable 1 and is horizontally positioned. The slide plate 35 is slidably fitted onto the guide rod 36 and slides horizontally. The function of the guide rod 36 is to prevent the slide plate 35 from rotating along with the lead screw 37. One end of the moving rod 33 is fixed to the side wall of the partition 32, and the other end passes through the replenishment tank 31, extends outward, and is fixedly connected to the slide plate 35.

[0036] See Figure 1One end of the connecting pipe 34 is connected to the replenishment tank 31, and the other end is connected to the discharge tank 21. The handwheel 38 is fixed to the lead screw 37, and the handwheel 38 facilitates the rotation of the lead screw 37. If the tire sealant in the discharge tank 21 is insufficient, the handwheel 38 is used to rotate the lead screw 37 to drive the slide plate 35 to move closer to the replenishment tank 31. That is, the moving rod 33 drives the partition plate 32 to move, so that the partition plate 32 squeezes the tire sealant into the discharge tank 21 to replenish the discharge tank 21, thereby ensuring the continuous filling of tire sealant into the tank.

[0037] See Figure 1 Furthermore, a positioning assembly is provided on the workbench 1. The positioning assembly includes a positioning part 4, which includes a positioning plate 41 and a pushing cylinder 42. The pushing cylinder 42 is installed on the side wall of the workbench 1. In this embodiment, the pushing cylinder 42 is controlled by a PLC controller. The output shaft of the pushing cylinder 42 is fixedly connected to the positioning plate 41. The positioning plate 41 is L-shaped and located above the conveyor belt mechanism 11. During the transport of the tank, the pushing cylinder 42 is activated to push the positioning plate 41. Subsequently, the tank will contact the positioning plate 41 until the second tank contacts the positioning plate 41. At this point, the conveyor belt mechanism 11 is stopped, thereby ensuring that the discharge pipe 23 is aligned with the opening of the tank, thus minimizing waste of tire sealant.

[0038] See Figure 1 Furthermore, a limit rod 12 is fixedly installed on the workbench 1. The limit rod 12 is located at both ends of the conveyor belt mechanism 11 along the width direction, and two limit rods 12 are provided at each end. The two limit rods 12 are arranged vertically. The limit rods 12 are used to limit the tank, so that the conveyor belt mechanism 11 can stably transport the tank, so that the tank is not easy to tilt or tip over.

[0039] The working principle of Example 1 is as follows: During filling, multiple tanks are placed sequentially on the conveyor belt mechanism 11, and the conveyor belt mechanism 11 is controlled to transport the tanks sequentially to the discharge pipe 23; then the solenoid valve 22 is controlled to open the discharge pipe 23 to fill the tanks with tire sealant; when the tanks are full, the control valve closes the discharge pipe 23 to stop filling, and the conveyor belt mechanism 11 transports the subsequent tanks to the discharge pipe 23 again. This not only saves labor, but also eliminates the need for manual judgment of the filling progress, thereby improving the filling efficiency of tire sealant.

[0040] Example 2: See Figure 4 The difference between this embodiment and Embodiment 1 is that the positioning component further includes a driving part 5 and an extension part 6.

[0041] See Figure 5The drive unit 5 includes a support rod 51, a rack 52, a gear 53, a drive rod 54, and a pull rope 55. The rack 52 is fixed to the positioning plate 41. The support rod 51 is fixed to the side wall of the worktable 1 and is located on the same side of the worktable 1 as the push cylinder 42. The drive rod 54 is rotatably mounted on the top wall of the support rod 51 via a bearing, and the gear 53 is coaxially sleeved on the drive rod 54, meshing with the rack 52. One end of the pull rope 55 is wound around the drive rod 54, and the other end is connected to the extension part 6.

[0042] See Figure 6 , Figure 7 and Figure 8 The extension part 6 includes an extension tube 61, an annular plate 62, and a compression spring 63. The extension tube 61 is disposed inside the discharge pipe 23 and can slide along the axis of the discharge pipe 23. An annular groove 231 is formed on the inner side wall of the discharge pipe 23, and an annular groove 232 is formed on the inner top wall of the groove 231. One end of the annular plate 62 is disposed in the groove 231 and the other end is disposed in the groove 232, and it slides in the vertical direction. The annular plate 62 is fixedly sleeved on the extension tube 61, and the end of the pull rope 55 away from the drive rod 54 passes through the groove 232 and is fixedly connected to the top wall of the annular plate 62.

[0043] See Figure 8 One end of the compression spring 63 is fixed to the inner top wall of the annular groove 232, and the other end is fixed to the top wall of the annular plate 62. The compression spring 63 is used to press down the annular plate 62. During the transportation of the tank, the push cylinder 42 is activated to push the positioning plate 41 to move half a distance, that is, to ensure that the tank can contact the positioning plate 41, so as to achieve the effect of positioning the tank. During this process, the gear 53 drives the drive rod 54 to rotate, the drive rod 54 releases the pull rope 55, and through the downward pressure of the compression spring 63, the annular plate 62 will drive the insertion tube 61 to move downward, thereby approaching the tube body. After positioning the two tanks, the push cylinder 42 is activated again to push the positioning plate 41 to move the remaining half distance. During this process, the insertion tube 61 continues to move downward and is inserted into the tank body, so that during filling, the tire sealant will be poured into the tank body through the insertion tube 61, to further ensure that the tire sealant is completely poured into the tank body, thereby avoiding waste.

[0044] See Figure 8 Furthermore, the insertion part 6 also includes a sealing sleeve 64, which is fixedly sleeved on the ring plate 62 and abuts against the inner wall of the ring groove 232. The sealing sleeve 64 is made of rubber and can improve the sealing between the ring plate 62 and the inner wall of the ring groove 232, so that the tire sealant is less likely to leak.

[0045] See Figure 8Furthermore, the insertion tube 61 is provided with a splash-proof component, which includes a splash-proof part 7 and an enlarged part 8.

[0046] See Figure 8 The splash-proof part 7 includes: a slider 71, a sleeve 72, a sealing gasket 73, and a return spring 74. A mounting groove 611 is provided on the side wall of the insertion tube 61 along the axial direction. The slider 71 is slidably disposed within the mounting groove 611 and slides vertically. The sleeve 72 is fitted onto the insertion tube 61 and is fixedly connected to the slider 71. The sealing gasket 73 is fixed to the bottom wall of the sleeve 72 and is made of rubber. The sealing gasket 73 improves the sealing performance between the sleeve 72 and the tank body.

[0047] See Figure 8 One end of the return spring 74 is fixedly connected to the inner top wall of the mounting groove 611, and the other end is fixedly connected to the slider 71. The return spring 74 is used to reset the slider 71. During the process of the insertion tube 61 extending into the tank, the sealing gasket 73 will contact the top wall of the tank, and the slider 71 will slide upward relative to it. Thus, the return spring 74 presses the sealing gasket 73 against the tank to seal the opening of the tank. This prevents the tire sealant from splashing out of the tank during the filling process, thus avoiding waste.

[0048] See Figure 8 The enlargement section 8 includes: a pressure rod 81, a pressure plate 82, a movable plate 83, a rubber sleeve 84, a hose 85, and a connecting spring 86. A receiving cavity 233 is provided on the discharge pipe 23. The receiving cavity 233 is annular and located below the slide groove 231, and contains water. Both the pressure plate 82 and the movable plate 83 are slidably disposed within the receiving cavity 233 and slide vertically, with the pressure plate 82 positioned above the movable plate 83. One end of the movable rod 33 is fixed to the top wall of the pressure plate 82, and the other end extends through the slide groove 231.

[0049] See Figure 8 A connecting spring 86 is fixed between the pressure plate 82 and the movable plate 83. The connecting spring 86 connects the pressure plate 82 and the movable plate 83 and facilitates the upward movement of the movable plate 83. A rubber sleeve 84 is fixedly sleeved on the side wall of the movable plate 83 and abuts against the inner wall of the accommodating cavity 233. The rubber sleeve 84 improves the sealing between the movable plate 83 and the inner wall of the accommodating cavity 233.

[0050] See Figure 8The sealing gasket 73 has a water storage cavity 731 inside. One end of the hose 85 is connected to the receiving cavity 233, and the other end is connected to the water storage cavity 731. In this embodiment, the hose 85 is long enough, and multiple hoses 85 are provided. During the downward movement of the ring plate 62, the ring plate 62 contacts the pressure rod 81 and presses down on the pressure rod 81. The pressure rod 81 pushes the pressure plate 82 and the moving plate 83 downward, thereby squeezing the water in the receiving cavity 233 into the water storage cavity 731 to increase the volume of the sealing gasket 73. After the sealing gasket 73 abuts against the tank body, the sealing gasket 73 will expand in all directions, thereby adapting to the opening size of different tanks and improving applicability.

[0051] The working principle of Example 2 is as follows: During the transportation of the tank, the push cylinder 42 is activated to move the positioning plate 41 halfway, ensuring that the tank can contact the positioning plate 41 to achieve the effect of positioning the tank. During this process, the gear 53 drives the drive rod 54 to rotate, the drive rod 54 releases the pull rope 55, and through the downward pressure of the compression spring 63, the ring plate 62 will drive the insertion tube 61 to move downward, thus approaching the tank. After positioning the two tanks, the push cylinder 42 is activated again to move the positioning plate 41 another halfway. During this process, the insertion tube 61 continues to move downward and is inserted into the tank. Thus, during filling, the tire sealant will be poured into the tank through the insertion tube 61, further ensuring that the tire sealant is completely poured into the tank, thus preventing waste.

[0052] This application also provides a filling method for an automated tire sealant filling device.

[0053] A filling method for an automated tire sealant filling device includes the following steps: S1: Multiple tanks are placed sequentially on the conveyor belt mechanism 11 and transported by the conveyor belt mechanism 11; S2: Whenever the tank is transported to the bottom of the discharge pipe 23, the positioning plate 41 is used to position the tank to ensure that the discharge pipe 23 is aligned with the opening of the tank; S3: Control solenoid valve 22 to open discharge pipe 23 to fill tire sealant into the tank.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
