Description

Technical Field

[0001] This utility model relates to the field of inner tube shaping technology, and in particular to an automatic inflatable and shaping tire inner tube inflator. Background Technology

[0002] Inner tubes, also known as tire inner tubes, are circular elastic tubes with valves used to maintain tire pressure. The valves are used to inflate the tires and maintain a certain pressure inside. Inner tubes should have good airtightness, heat resistance, elasticity, aging resistance, and minimal permanent deformation. They are generally made of butyl rubber. Inner tubes are air-bearing containers used for inflation and vibration damping. They are auxiliary air-bearing containers used in the inner cavity of tires of automobiles, motorcycles, bicycles, and rickshaws. According to the main materials they contain, they can be divided into natural rubber inner tubes and butyl rubber inner tubes. Inner tube shaping devices are required during the manufacturing of inner tubes.

[0003] Existing inner tube shaping devices, such as the one disclosed in patent CN221697988U, involve a bicycle inner tube shaping device. A motor drives one gear to rotate, which in turn drives a gear ring. The gear ring's rotation drives several other gears, which in turn drive a rack meshing with it to move relative to or away from each other. This, in turn, drives multiple shaping plates to move coaxially. The position of the shaping plates is adjusted according to the size of the inner tube. After the inner tube is inflated and shaped, the relative movement of the racks allows the shaping plates to shrink and move coaxially, facilitating the removal of the inner tube and the shaping of inner tubes of different sizes. However, in practical use, this patent primarily uses the shaping plates to restrict the inner tube's position. As the shaping plates move coaxially, gaps appear between adjacent plates, causing the inner tube to not be completely flush against them. The unflush parts may deform during the shaping process, making it inconvenient for practical use. Utility Model Content

[0004] The purpose of this invention is to provide an automatic inflation and shaping machine for tire inner tubes, which solves the problem that while the inner tube is restricted by a shaping plate, gaps will exist between adjacent shaping plates as the shaping plates move coaxially. This causes the inner tube to not be completely attached to the shaping plate, and the unattached parts will deform during the shaping process, making it inconvenient for practical use.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An automatic tire inner tube inflation and shaping machine includes a worktable, a crossbar fixedly mounted on the surface of the worktable, an electric telescopic rod fixedly mounted on the surface of the crossbar, a connecting sleeve rotatably connected to the output end of the electric telescopic rod, a tray rotatably connected to the surface of the worktable, and a mold body provided on the surface of the tray. The mold body includes an upper mold and a lower mold. The upper mold is installed at the bottom of the connecting sleeve, and the lower mold is installed on the surface of the tray. Both the upper mold and the lower mold are annular structures, and annular rods are provided on the sides of the upper mold and the lower mold that are close to each other. The outer walls of the two annular rods are both set with an arc-shaped structure to achieve a state of mutual contact with the surface of the inner tube.

[0007] Preferably, a first insert rod is fixedly installed on the top of the upper mold, a second insert rod is fixedly installed on the bottom of the lower mold, insertion holes are opened on the bottom of the connecting sleeve and the surface of the tray, bolts are threadedly connected to the side wall of the connecting sleeve, threaded holes are opened on the surface of the first insert rod, an iron block is fixedly installed inside the insertion hole on the surface of the tray, and a magnet is fixedly installed at the bottom end of the second insert rod.

[0008] Preferably, the surface of the second insertion rod is provided with protrusions to prevent relative rotation after the second insertion rod is inserted into the insertion hole on the tray surface.

[0009] Preferably, a positioning rod is fixedly installed on the top of the lower mold, and a positioning groove adapted to the size of the positioning rod is opened on the bottom of the upper mold.

[0010] Preferably, a motor is fixedly installed at the bottom of the workbench, and the output shaft port of the motor is fixedly connected to the tray.

[0011] Preferably, both the upper and lower molds have arc-shaped grooves on their surfaces to accommodate the inner tube valve.

[0012] This utility model has at least the following beneficial effects:

[0013] Install the corresponding mold body according to the size of the inner tube. The upper mold is installed on the connecting sleeve, and the lower mold is installed on the tray. Then, the inner tube is placed on the outer wall of the annular frame inside the lower mold. The upper mold is then moved downward using an electric telescopic rod so that the upper mold and the lower mold overlap. At this time, air is injected into the valve on the inner tube so that the inner tube is fully filled, and the surface of the inner tube can completely fit the surface of the annular frame, the upper mold, and the lower mold. The inner walls of the upper mold and the lower mold are both set as arc surfaces that adapt to the arc shape of the inner tube. Combined with the annular frame with an outer ring structure, a good shaping effect is achieved. Attached Figure Description

[0024] Reference Figure 1-3 An automatic tire inner tube inflation and shaping machine includes a worktable 1. A crossbar 2 is fixedly installed on the surface of the worktable 1. An electric telescopic rod 3 is fixedly installed on the surface of the crossbar 2. A connecting sleeve 5 is rotatably connected to the output end of the electric telescopic rod 3. A tray 7 is rotatably connected to the surface of the worktable 1. A mold body 4 is provided on the surface of the tray 7. The mold body 4 includes an upper mold 41 and a lower mold 42. The upper mold 41 is installed at the bottom of the connecting sleeve 5, and the lower mold 42 is installed on the surface of the tray 7. Both the upper mold 41 and the lower mold 42 are annular structures, and annular rods 43 are provided on the sides of the upper mold 41 and the lower mold 42 that are close to each other. The outer walls of the two annular rods 43 are both set with an arc-shaped structure to achieve a fit with the surface of the inner tube. In use, the mold body 4 of the corresponding size is first installed according to the size of the inner tube. The upper mold 41 is installed on the connecting sleeve 5, and the lower mold 42 is installed on the tray 7. Then, the inner tube is placed on the outer wall of the annular frame 43 inside the lower mold 42. The upper mold 41 is then moved downward using the electric telescopic rod 3 so that the upper mold 41 and the lower mold 42 overlap. At this time, air is inflated into the valve on the inner tube so that the inner tube is fully filled, and the surface of the inner tube can completely fit the surface of the annular frame 43, the upper mold 41, and the lower mold 42. The inner walls of the upper mold 41 and the lower mold 42 are both set as arc surfaces that match the arc shape of the inner tube. Combined with the annular frame 43 with an annular outer wall structure, a good shaping effect is achieved.

[0025] Furthermore, a first insert rod 45 is fixedly installed on the top of the upper mold 41, and a second insert rod 46 is fixedly installed on the bottom of the lower mold 42. Insertion holes are provided on the bottom of the connecting sleeve 5 and the surface of the tray 7. Bolts 6 are threadedly connected to the side wall of the connecting sleeve 5. Threaded holes are provided on the surface of the first insert rod 45. An iron block is fixedly installed inside the insertion hole on the surface of the tray 7. A magnet block 47 is fixedly installed at the bottom of the second insert rod 46. The upper mold 41 is inserted into the insertion hole inside the connecting sleeve 5 using the first insert rod 45 and then fixed using the bolts 6. The lower mold 42 is inserted into the insertion hole on the tray 7 using the second insert rod 46. An iron piece is provided in the insertion hole on the tray 7. With the help of the magnet block 47 at the bottom of the second insert rod 46, the second insert rod 46 can be attracted to the tray 7. In this way, when the upper mold 41 moves upward, the lower mold 42 will not detach from the tray 7. Moreover, the upper mold 41 and the lower mold 42 are installed in this way, which facilitates disassembly and makes it easy to change different molds according to different inner tubes.

[0026] Furthermore, the surface of the second insertion rod 46 is provided with protrusions to ensure that the second insertion rod 46 cannot rotate relative to the insertion hole on the surface of the tray 7 after being inserted.

[0027] Furthermore, a positioning rod 44 is fixedly installed on the top of the lower mold 42, and a positioning groove 48 that matches the size of the positioning rod 44 is opened at the bottom of the upper mold 41. The positioning rod 44 and the positioning groove 48 make it easier for the upper mold 41 and the lower mold 42 to be merged, and also allow the upper mold 41 and the lower mold 42 to rotate synchronously.

[0028] Furthermore, a motor 8 is fixedly installed at the bottom of the workbench 1. The output shaft port of the motor 8 is fixedly connected to the tray 7. By setting the motor 8, the tray 7 can be driven to rotate, thereby driving the upper mold 41 and the lower mold 42 to rotate, which facilitates all-round observation of the inner tube condition and facilitates inflation of the inner tube valve.

[0029] Furthermore, both the upper mold 41 and the lower mold 42 have arc-shaped grooves on their surfaces to accommodate the inner tube valve.

[0030] In summary, during use, the mold body 4 of the corresponding size is first installed according to the inner tube size. The upper mold 41 is installed on the connecting sleeve 5, and the lower mold 42 is installed on the tray 7. Then, the inner tube is placed on the outer wall of the annular frame 43 inside the lower mold 42. The upper mold 41 is then moved downward using the electric telescopic rod 3 so that the upper mold 41 and the lower mold 42 overlap. At this time, air is inflated into the valve on the inner tube so that the inner tube is fully filled, allowing the surface of the inner tube to completely conform to the surfaces of the annular frame 43, the upper mold 41, and the lower mold 42. The inner walls of the upper mold 41 and the lower mold 42 are both set as arc surfaces that adapt to the arc shape of the inner tube. Combined with the annular frame 43 with its annular outer wall structure, a good shaping effect is achieved. The upper mold 41 is inserted into the insertion hole inside the connecting sleeve 5 using the first insertion rod 45, and then fixed with bolts 6. The mold 42 is inserted into the insertion hole on the tray 7 using the second insertion rod 46. The insertion hole on the tray 7 is equipped with an iron piece, which, together with the magnet 47 at the bottom of the second insertion rod 46, allows the second insertion rod 46 to be attracted to the tray 7. This prevents the lower mold 42 from detaching from the tray 7 when the upper mold 41 moves upward. Moreover, the installation of the upper mold 41 and the lower mold 42 in this way facilitates disassembly, making it easy to change different molds according to different inner tubes. The positioning rod 44 and the positioning groove 48 make it easier for the upper mold 41 and the lower mold 42 to be combined, and also allow the upper mold 41 and the lower mold 42 to rotate synchronously. The motor 8 drives the tray 7 to rotate, thereby driving the upper mold 41 and the lower mold 42 to rotate, which facilitates all-round observation of the inner tube and convenient inflation of the inner tube valve.
