AI Technical Summary
The supply and return flow control of the existing vulcanization machine robot lifting cylinders does not match, resulting in the slow drop speed of the robot falling too quickly, which can easily damage the equipment.
A supply and return flow conversion device including a shell, baffle and pressure spring is designed. By adjusting the water flow channel design, the return water flow is greater than the water supply flow, thereby achieving accelerated decline of the robot while avoiding the rise too fast.
The accelerated decline of the robot is achieved, avoiding equipment damage, and improving tire assembly efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire production equipment, and particularly relates to a device for converting the supply and return water flow of a lifting water cylinder of a manipulator of a vulcanizer. Background Art
[0002] The lifting water cylinder of the tire loading manipulator of a mechanical vulcanizer is a single-acting water cylinder. When the manipulator rises, power water is supplied through the water cylinder pipeline and injected into the single-acting water cylinder to generate an upward lifting force with a pressure of 2.2 MPa. When the manipulator descends, it can only rely on its own gravity to discharge the power water in the single-acting water cylinder, so as to make the manipulator descend. In actual use, the descending speed of the manipulator is very slow, affecting the tire loading efficiency. If the diameter of the water cylinder pipeline is simply increased, the manipulator will rise too fast, which is likely to cause damage to the equipment. There is an urgent need for a device that can control the supply and return water flow of the power water to match the on-site use requirements. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a device for converting the supply and return water flow of a lifting water cylinder of a manipulator of a vulcanizer aiming at the defects existing in the prior art.
[0004] The technical solution of the utility model is: a device for converting the supply and return water flow of a lifting water cylinder of a manipulator of a vulcanizer, including a housing, a baffle and a compression spring. One end of the housing is provided with a first water passing port close to the lifting water cylinder, and the other end is provided with a second water passing port. The baffle is located inside the housing, its outer diameter is smaller than the inner diameter of the housing, and a through hole coaxially arranged with the first water passing port is opened at the center thereof. The aperture of the through hole is smaller than the inner diameter of the first water passing port. One end of the compression spring is fixed on the back of the baffle, and the other end is fixed on the inner wall of the housing where the second water passing port is located. When power water is supplied through the water cylinder pipeline, the baffle fits on the inner wall of the housing where the first water passing port is located.
[0005] Preferably, the housing is a cylinder.
[0006] Preferably, the first water passing port and the second water passing port are coaxially arranged and are both located at the center of the end of the housing.
[0007] Preferably, the inner diameters of the first water passing port and the second water passing port are equal.
[0008] Compared with the prior art, the utility model has the following advantages:
[0009] The device has a simple structure and strong practicability. It can make the return water flow greater than the supply water flow, and while realizing the accelerated descent of the manipulator, it can also prevent the manipulator from rising too fast and causing damage to the equipment.

[0013] The following further describes the present utility model in conjunction with the drawings and embodiments. Embodiment 1
[0014] Referring to Figure 1-2 As shown, a return flow conversion device for the lifting water cylinder 1 of a vulcanizer manipulator includes a housing 4, a baffle plate 5 and a compression spring 6. The housing 4 is a cylinder, one end of which is provided with a first water passing port 401 close to the lifting water cylinder 1, and the other end is provided with a second water passing port 402. The baffle plate 5 is located inside the housing 4, its outer diameter is smaller than the inner diameter of the housing 4, and a through hole 501 coaxially arranged with the first water passing port 401 is opened at its center. The aperture of the through hole 501 is smaller than the inner diameter of the first water passing port 401. One end of the compression spring 6 is fixed on the back of the baffle plate 5, and the other end is fixed on the inner wall of the housing 4 where the second water passing port 402 is located. When the water cylinder pipeline 2 supplies power water, the baffle plate 5 fits on the inner wall of the housing 4 where the first water passing port 401 is located.
[0015] The inner diameters of the first water passing port 401 and the second water passing port 402 are equal, and both are connected to the thickened water cylinder pipeline 2.
[0016] More specifically, the first water passing port 401 and the second water passing port 402 are coaxially arranged, and both are located at the center of the end of the housing 4.
[0017] During use, the diameter of the water cylinder pipeline 2 is increased, and this device is installed on the water cylinder pipeline 2 between the lifting water cylinder 1 and the conversion valve 3. When supplying power water, the power water enters the inner cavity of the housing 4 through the second water passing port 402, and then flows to the lifting water cylinder 1 through the through hole 501 and the first water passing port 401 in sequence. Since the aperture of the through hole 501 is smaller than the inner diameter of the first water passing port 401, the water supply flow rate will not increase significantly, thus avoiding damage to the equipment caused by the too-fast rising of the manipulator. When discharging the power water, the power water enters the inner cavity of the housing 4 through the first water passing port 401, and presses the baffle plate 5 to the right, thereby increasing the flow passage, so that the return water flow rate is greater than the water supply flow rate, realizing the accelerated descent of the manipulator.
[0018] This device has a simple structure and strong practicability. It can make the return water flow rate greater than the water supply flow rate. While realizing the accelerated descent of the manipulator, it can also avoid damage to the equipment caused by the too-fast rising of the manipulator.
[0019] The present utility model is not limited to the above-mentioned embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present utility model, and the changed content still falls within the protection scope of the present utility model.
