Description

Technical Field

[0001] This application relates to the field of tire inner tube processing technology, and more specifically, to a flipping mechanism for a tire inner tube vulcanizing machine. Background Technology

[0002] The tire inner tube vulcanizing machine is a key piece of equipment for achieving the vulcanization and molding of tire inner tubes. The inner tube to be vulcanized is first placed in the mold groove of the lower mold. The vulcanizing machine forms a sealed space by lowering and closing the upper mold, thus completing the vulcanization of the tire inner tube. Afterwards, the upper mold needs to be raised to remove the vulcanized inner tube.

[0003] In related technologies, to facilitate the demolding of vulcanized inner tubes, for example, the prior art patent with publication number CN210282928U provides a flipping mechanism for a tire inner tube vulcanizing machine. This flipping mechanism hooks the hook to the lifting ring, drives the rotating shaft to rotate through the motor, and drives the rotating wheel to rotate. The lower pressure plate is pulled up through the wire rope, so that the lower pressure plate is at a certain angle to the horizontal plane. At this time, the vulcanized tire inner tube is easier to demold, and it is more convenient and faster for the operator to pick up the tire inner tube, reducing the workload of the operator and increasing efficiency.

[0004] Although the existing technical solutions mentioned above facilitate the inner tube feeding by setting hooks and lifting rings, there is no guiding or positioning structure between the hooks and lifting rings. The hooks and lifting rings are not easy to match and require precise manual alignment, which is inconvenient to operate. This makes it difficult to feed the vulcanized inner tubes and reduces production efficiency.

[0005] In view of this, we propose a flipping mechanism for a tire inner tube vulcanizing machine. Utility Model Content

[0006] The purpose of this application is to provide a flipping mechanism for a tire inner tube vulcanizing machine, which can effectively solve the problem in the prior art that requires manual alignment of hooks and lifting rings, resulting in inconvenience in unloading the vulcanized inner tube, and achieve the effect of facilitating the unloading of the vulcanized inner tube.

[0007] This application provides a flipping mechanism for an inner tube vulcanizing machine, comprising:

[0008] A support plate, wherein the support plate is disposed on the inner side of the vulcanizing lower mold;

[0009] A flipping component, located on one side of the support plate, is used to drive the support plate to flip.

[0010] A lifting plate is located at the bottom of the flipping assembly, and the lifting plate is driven by an external force to move the flipping assembly up and down;

[0011] A rotating plate is located at the bottom of the lifting plate, and the rotating plate is driven by an external force to rotate the lifting plate.

[0012] As an optional solution to the technical solution of this application, a connecting plate is fixedly provided on the side of the support plate near the flipping assembly. The grooves on the top of the support plate and the connecting plate cooperate with the vulcanizing lower mold. The flipping assembly includes a semi-toothed column, which is fixedly provided at the bottom of the connecting plate. A toothed plate is provided at the bottom of the semi-toothed column. The toothed plate is fixedly provided at the output end of the electric push rod B. The electric push rod B is fixedly provided at the top of the lifting plate.

[0013] As an optional solution to the technical solution of this application, a rotating shaft is fixedly provided on the inner side of the semi-tooth column, the rotating shaft is rotatably disposed on the inner side of two bearing plates, and the bearing plates are fixedly disposed on the top of the lifting plate.

[0014] As an optional solution to the technical solution of this application, the top of the lifting plate is provided with a sliding groove, and a slider is slidably arranged on the inner side of the sliding groove, and the slider is fixedly arranged on the bottom of the toothed plate.

[0015] As an optional solution to the technical solution of this application, the lifting plate is fixedly installed at the output end of the electric push rod C, and the electric push rod C is fixedly installed at the top of the rotating plate.

[0016] As an optional solution to the technical solution of this application, the rotating plate is fixedly installed at the output end of the drive motor, and the top of the rotating plate is provided with two sets of support plates, a flipping assembly and a lifting plate.

[0017] As an optional solution to the technical solution of this application, a set of lifting blocks is slidably arranged on the inner side of the support plate, and a lifting plate is fixedly arranged at the bottom of the lifting blocks. The lifting plate is fixedly arranged at the output end of the electric push rod A, and the electric push rod A is fixedly arranged at the bottom of the support plate by a fixing frame.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] (1) This application uses a flipping component. After the inner tube is vulcanized, it is cooled by an external cooling mechanism. Then, the flipping component and its connected support plate are lifted by the lifting plate to demold the tire from the vulcanization mold. Then, the lifting plate and its connected flipping component and support plate are rotated by the rotating plate to move the inner tube to the unloading point. The inner tube is unloaded by the flipping component driving the support plate to rotate. Therefore, it effectively solves the problem in the prior art that it is inconvenient to unload the vulcanized inner tube because it requires manual alignment of the hook and lifting ring. It achieves the effect of easy demolding and unloading of the vulcanized inner tube.

[0020] (2) This application slides a lifting block inside the support plate. After the inner tube of the vulcanized tire cools down, the lifting plate is pushed up by the electric push rod A, thereby pushing the lifting block up so that the lifting block extends into the inner tube and the inner tube is not easy to fall off during subsequent movement.

Detailed Implementation

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 This application discloses a flipping mechanism for a tire inner tube vulcanizing machine, including a support plate 1. The support plate 1 is disposed inside the vulcanizing lower mold 100. A flipping component 2 is disposed on one side of the support plate 1 for driving the support plate 1 to flip. A lifting plate 3 is disposed at the bottom of the flipping component 2. The lifting plate 3 is driven by an external force to move the flipping component 2 up and down. A rotating plate 4 is disposed at the bottom of the lifting plate 3. The rotating plate 4 is driven by an external force to move the lifting plate 3 to rotate.

[0028] Before vulcanization, the flipping mechanism needs to be pre-installed inside the vulcanization lower mold 100 to ensure that the top of the support plate 1 fits against the bottom of the mold groove of the vulcanization lower mold 100. After the inner tube has completed vulcanization in the vulcanization lower mold 100 and the vulcanization upper mold, the inner tube is cooled by the cooling mechanism. The lifting plate 3 drives the flipping component 2 and the support plate 1 to rise to demold the inner tube. Then, the rotating plate 4 drives the lifting plate 3, the flipping component 2 and the support plate 1 to rotate to achieve position transfer, so that the inner tube moves to the unloading position. Then, the flipping component 2 drives the support plate 1 to flip to unload the inner tube, thus realizing automatic demolding and unloading of the inner tube. The vulcanization lower mold 100, the vulcanization upper mold and the cooling mechanism are all existing technical equipment. For details, please refer to the patent with technical publication number CN210282928U, which provides a flipping mechanism for a vulcanizing machine for inner tubes. It will not be described in detail here.

[0029] Reference Figure 1 - Figure 4 A connecting plate 11 is fixedly installed on the side of the support plate 1 near the flipping assembly 2. The grooves on the top of the support plate 1 and the connecting plate 11 cooperate with the vulcanizing lower mold 100. The flipping assembly 2 includes a semi-toothed column 21, which is fixedly installed at the bottom of the connecting plate 11. A toothed plate 22 is provided at the bottom of the semi-toothed column 21, and the toothed plate 22 is fixedly installed at the output end of the electric push rod B23. The electric push rod B23 is fixedly installed at the top of the lifting plate 3. A rotating shaft 211 is fixedly installed on the inner side of the semi-toothed column 21, and the rotating shaft 211 is rotatably set. Inside the two bearing plates 212, the bearing plates 212 are fixedly installed on the top of the lifting plate 3. The top of the lifting plate 3 is provided with a sliding groove 31. A slider 311 is slidably installed inside the sliding groove 31. The slider 311 is fixedly installed on the bottom of the toothed plate 22. The lifting plate 3 is fixedly installed at the output end of the electric push rod C32. The electric push rod C32 is fixedly installed on the top of the rotating plate 4. The rotating plate 4 is fixedly installed at the output end of the drive motor 41. The top of the rotating plate 4 is provided with two sets of support plates 1, a flipping assembly 2 and a lifting plate 3.

[0030] When it is necessary to drive the support plate 1 to flip, the electric push rod B23 is activated. The piston rod of the electric push rod B23 retracts, causing the toothed plate 22 to slide along the slide groove 31. The slider 311 slides synchronously with the toothed plate 22 to ensure that the toothed plate 22 moves smoothly. The toothed plate 22 drives the half tooth column 21 to rotate around the rotating shaft 211 through tooth surface meshing. The half tooth column 21 then drives the support plate 1 to flip synchronously through the connecting plate 11, realizing the angle adjustment of the support plate 1, so that the inner tube can slide down the support plate 1 at an angle to realize the feeding action.

[0031] When demolding is required, the electric push rod C32 is activated. The piston rod of the electric push rod C32 extends upward and pushes the lifting plate 3 to rise. The lifting plate 3 drives the flipping assembly 2, the connecting plate 11 and the support plate 1 to rise synchronously, so that the vulcanized inner tube on the support plate 1 separates from the mold groove of the vulcanized lower mold 100, and demolding is completed.

[0032] When the inner tube needs to be moved, the drive motor 41 is started. The output shaft of the drive motor 41 drives the rotating plate 4 to rotate. The rotating plate 4 drives the lifting plate 3, the flipping component 2 and the support plate 1 to rotate synchronously through the electric push rod C32, so as to transfer the inner tube from the vulcanizing station to the unloading station. The two sets of support plates 1, flipping component 2 and lifting plate 3 can operate at the vulcanizing station and the unloading station respectively to realize continuous production.

[0033] Reference Figure 3 and Figure 4 A set of lifting blocks 12 is slidably arranged on the inner side of the support plate 1. A lifting plate 13 is fixedly arranged at the bottom of the lifting block 12. The lifting plate 13 is fixedly arranged at the output end of the electric push rod A14. The electric push rod A14 is fixedly arranged at the bottom of the support plate 1 through the fixing frame 15.

[0034] After the vulcanized inner tube has cooled down, start the electric push rod A14. The piston rod of the electric push rod A14 extends upward and pushes the lifting plate 13 to rise. The lifting plate 13 drives a set of lifting blocks 12 to rise synchronously along the inner side of the support plate 1, so that the lifting blocks 12 extend into the inner side of the inner tube and support and limit the inner tube from the inside.

[0035] During the subsequent transfer of the inner tube by the rotating plate 4, the lifting block 12 can effectively prevent the inner tube from falling off the support plate 1 due to shaking or gravity, thus improving the stability of the transfer process.

[0036] In summary, when using the flipping mechanism for the inner tube vulcanizing machine disclosed in this application embodiment, the flipping mechanism needs to be pre-installed inside the vulcanizing lower mold 100 before vulcanization to ensure that the top of the support plate 1 fits against the bottom of the mold groove of the vulcanizing lower mold 100. After the inner tube has completed vulcanization in the vulcanizing lower mold 100 and vulcanizing upper mold, the inner tube is cooled by the cooling mechanism. Then, the electric push rod A14 is started, and the piston rod of the electric push rod A14 extends upward to push the lifting plate 13 to rise. The lifting plate 13 drives a set of lifting blocks 12 to rise synchronously along the inner side of the support plate 1, so that the lifting blocks 12 extend into the inner side of the inner tube and support and limit the inner tube from the inside.

[0037] By activating the electric push rod C32, the piston rod of the electric push rod C32 extends upward, pushing the lifting plate 3 to rise. The lifting plate 3 drives the flipping component 2, the connecting plate 11 and the support plate 1 to rise synchronously, so that the vulcanized inner tube on the support plate 1 separates from the mold groove of the vulcanized lower mold 100, and the demolding is completed.

[0038] Then the drive motor 41 is started. The output shaft of the drive motor 41 drives the rotating plate 4 to rotate. The rotating plate 4 drives the lifting plate 3, the flipping component 2 and the support plate 1 to rotate synchronously through the electric push rod C32, transferring the inner tube from the vulcanizing station to the unloading station.

[0039] Then, the electric push rod B23 is activated. The piston rod of the electric push rod B23 retracts, causing the toothed plate 22 to slide along the slide groove 31. The slider 311 slides synchronously with the toothed plate 22, ensuring that the toothed plate 22 moves smoothly. The toothed plate 22 drives the semi-tooth column 21 to rotate around the rotating shaft 211 through tooth surface meshing. The semi-tooth column 21 then drives the support plate 1 to rotate synchronously through the connecting plate 11, realizing the angle adjustment of the support plate 1, so that the inner tube can slide down along the support plate 1 at an angle to realize the feeding action.
