DETAILED DESCRIPTION

[0031] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0032] As a specific embodiment, the improved exhaust valve hot press feeding device of the embodiment of the utility model includes a feeding device 1, which includes an ejector 13, an output guide rail 15 and a feeding carrier 19 provided with a storage cavity 11. A guide rail cavity 151 for accommodating an exhaust valve (not shown in the accompanying drawings, which is substantially the same as the exhaust valve in CN217892073U) is provided in the output guide rail 15. The exhaust valve falls in the guide rail cavity 151 by its own weight and the weight of the exhaust valve above it, and is output from the output end of the guide rail cavity 151. Usually, the carrier top plate 192 of the feeding carrier 19 is movable, for example, it is hinged to the top of the fitting wall 16 or the top of the carrier side plate 191. The storage cavity 11 can be exposed by rotating the carrier top plate 192, so as to facilitate the addition of the exhaust valve into the storage cavity 11.

[0033] The ejector 13 is arranged in a close fit in the buffer cavity 12 and has the power to continuously and reciprocate without stopping. It is easy to understand that the thickness of the ejector 13 is roughly equal to the thickness of the buffer cavity 12 and fits well. For example, a driving device 18 in the form of a cylinder is fixedly arranged on the fitting wall 16 described later, and the output end of the driving device 18 is fixedly connected to the ejector 13. The output end of the driving device 18 is lifted and lowered back and forth, so that the ejector 13 has the power to lift and lower back and forth. Of course, the driving device 18 can also provide the power to lift and lower back and forth in other ways.

[0034] The loading carrier 19 includes a fitting wall 16 and a buffer cavity plate 121 . The fitting wall 16 , the buffer cavity plate 121 and the top end of the ejector 13 together form a buffer cavity 12 .

[0035] The bottom end surface of the storage cavity 11 is a storage cavity slope 111, and the buffer cavity 12 is located at the lowest point of the storage cavity slope 111 and is connected to the storage cavity 11. Due to its own weight, the exhaust valve in the storage cavity 11 approaches and falls into the buffer cavity 12 on the storage cavity slope 111. The thickness of the buffer cavity 12 is roughly the thickness of the exhaust valve, so the exhaust valves falling into the buffer cavity 12 are roughly vertical (that is, the axial centerline of the exhaust valve is roughly horizontal).

[0036] The part of the fitting wall 16 above the buffer cavity 12 is recessed to form an inclined rail 14 parallel to the ejector 13. It should be noted that the fitting wall 16 and the inclined rail 14 thereon are formed by combining multiple parts, which also means that the fitting wall 16 is recessed to form the inclined rail 14.

[0037] The inclined rail 14 includes an inclined rail groove 141 and an inclined rail groove support surface 143 located outside the inclined rail groove 141; Figure 5 As shown, an inclination angle 149 is set between the inclined rail 14 and the horizontal plane.

[0038] The lowest end of the inclined rail 14 is communicated with the output guide rail 15. For example, the output guide rail 15 is provided with a guide rail inlet 152 communicated with the guide rail cavity 151, and the lowest end of the inclined rail 14 is communicated with the guide rail inlet 152.

[0039] The working principle is that the ejector 13 is lifted and lowered back and forth to lift up the exhaust valve at its top (the exhaust valve is vertical, and the outer edge of the exhaust valve is closer to the fitting wall 16 than the exhaust valve body), so that the exhaust valve exceeds the inclined rail 14, and the exhaust valve tilts toward the fitting wall 16 and rolls along the inclined rail 14. In the exhaust valve, the exhaust valve whose outer edge enters the inclined rail groove 141, the exhaust valve body is supported by the inclined rail groove support surface 143 and can continue to roll along the inclined rail groove 141 until it rolls to the lowest end of the inclined rail 14, or is supported by other exhaust valves. In the exhaust valve, the exhaust valve whose outer edge does not enter the inclined rail groove 141, the exhaust valve outer edge rolls on the inclined rail groove support surface 143 and falls from the inclined rail 14 to the cache cavity 12 or the storage cavity 11. It is easy to understand that the thickness of the inclined rail 14 is roughly equal to the thickness of the exhaust valve, so that the exhaust valve is vertical.

[0040] In the process of the exhaust valve tilting toward the fitting wall 16 and rolling along the inclined rail 14, the ejector 13 does not need to maintain a position aligned with the guide rail inlet 152, but can continue to lift the exhaust valve after moving downward. Therefore, the ejector 13 can be lifted and lowered back and forth, so that the exhaust valve is always present on the inclined rail 14, so that the exhaust valve can be continuously output to the output guide rail 15, which is beneficial to improving production efficiency, reducing the height of the output guide rail 15 and reducing costs.

[0041] As one of the specific implementations, Figure 7 As shown, the lowest end of the ramp 14 is deflected downward by a drop height 145 to form a ramp extension section 144, and the ramp extension section 144 is connected to the output guide rail 15. For example, the ramp extension section 144 passes through the carrier side plate 191 and is connected to the guide rail inlet 152. When the exhaust valve at the drop height 145 enters the guide rail inlet 152, it will jump downward and slightly increase the speed of entering the guide rail inlet 152, thereby ensuring that the exhaust valve enters the guide rail inlet 152.

[0042] As one of the specific implementations, the top end of the ejector 13 is arranged horizontally.

[0043] As one of the specific implementations, the top of the ejector 13 is provided with an ejector outer edge groove 131 and an ejector support surface 133 located outside the ejector outer edge groove 131; the ejector outer edge groove 131 is in contact with the fitting wall 16. It can ensure that the exhaust valves at the top of the ejector 13 are in a posture where the outer edges of the exhaust valves are close to the fitting wall 16.

[0044] As one of the specific implementations, when the ejector 13 rises to the maximum height, the top of the ejector 13 exceeds the highest end of the ramp 14. Exhaust valves lifted by the ejector 13 may exist on the entire ramp 14, which can increase the probability of having exhaust valves with required postures on the ramp 14, thereby improving the reliability of exhaust valves output by the ramp 14.

[0045] As one of the specific implementations, a pre-blocking plate 112 is fixedly disposed in the storage cavity 11 ; the bottom end of the pre-blocking plate 112 and the storage cavity inclined surface 111 are combined to form a material passing hole 113 .

[0046] As one of the specific implementations, the cross-sectional area of ​​the feeding hole 113 near the bottom end of the inclined rail 14 (the plane intercepted along the plane of the pre-blocking plate 112) is smaller than the cross-sectional area of ​​the feeding hole 113 near the top end of the inclined rail 14. For example, the cross section of the feeding hole 113 is a triangle. The exhaust valve moves downward due to its own weight on the storage chamber inclined surface 111. After passing through the feeding hole 113, more exhaust valves enter the buffer chamber 12 near the top end of the inclined rail 14 (or accumulate above the buffer chamber 12 on the top end of the inclined rail 14) and are located near the bottom end of the inclined rail 14, which can improve the reliability of the output exhaust valve.

[0047] As one of the specific implementations, a pre-blocking plate inclination angle 114 is provided between the pre-blocking plate 112 and the vertical plane, and the top of the pre-blocking plate inclination angle 114 is closer to the ejector 13 than the bottom thereof. When the ejector 13 moves upward and pushes up the exhaust valves gathered at the top opening of the buffer chamber 12, in this process, the pre-blocking plate inclination angle 114 limits the pushed-up exhaust valves, making them have a tendency to approach the top opening of the buffer chamber 12 (there is also a certain interaction force between the exhaust valves); when the ejector 13 moves downward and sinks into the top opening of the buffer chamber 12, the exhaust valves gathered at the top opening of the buffer chamber 12 are easier to enter the buffer chamber 12 due to the tendency to approach the top opening of the buffer chamber 12, that is, the exhaust valves gathered at the top opening of the buffer chamber 12 can enter the buffer chamber 12 more easily, that is, the exhaust valves gathered at the top opening of the buffer chamber 12 can enter the buffer chamber 12 more easily, thereby improving reliability.

[0048] As one of the specific implementations, Figure 5 As shown, one side of the ejector 13 is flush with the side where the highest end of the ramp 14 is located, and the width of the ejector 13 is smaller than the width of the ramp 14 ( Figure 5 The embodiment in which the width of the ejector 13 is equal to the width of the ramp 14 is shown, and the width of the ejector 13 is smaller than the width of the ramp 14 is not shown). Even the exhaust valve lifted by the portion of the ejector 13 closest to the lowest end of the ramp 14 has a distance to roll toward the ramp 14, which can increase the probability of the exhaust valve in the required posture existing on the ramp 14, thereby improving the reliability of the exhaust valve output by the ramp 14.

[0050] As used in the present invention, the terms "a", "an", etc. do not indicate a limitation of quantity, but rather indicate the presence of at least one of the referenced object.
