Specific embodiments

[0034] The specific embodiments of the utility model will be explained below by referring to the specification drawings.

[0035] As a specific embodiment, the improved exhaust valve continuous heat pressing device of the embodiment of the utility model comprises a feeding device 1, a heat pressing device 2 and a continuous conveying device 3.

[0036] The feeding device 1 comprises an L-shaped (the two ends of the L shape have an approximately right angle between them) exhaust valve output guide rail 15 for outputting single-row exhaust valves 9. It is easy to understand that the single-row exhaust valves 9 are arranged in the exhaust valve output guide rail 15 at a time, and have a tendency to move towards the output end of the exhaust valve output guide rail 15 by relying on the gravity of the exhaust valves 9 themselves. It is easy to understand that the exhaust valve 9 comprises an exhaust valve body 92 which is a whole cylinder, and the top end of the exhaust valve body 92 extends outward to form a circular exhaust valve rim 91. The exhaust valve 9 is usually made of plastic or the like. Referring to the improved exhaust valve hot press feeding device disclosed in the prior art CN118876490A, the feeding device 1 usually further comprises a storage cavity 11 having a storage cavity inclined surface 111, and the reciprocating ejector 13 ejects the storage cavity inclined surface 111 onto the inclined rail 14 and then outputs from the inclined rail outlet 141 to the inlet end of the exhaust valve output guide rail 15.

[0037] The hot pressing device 2 comprises a hot press frame 29 and a hot pressing body 21 which is fixed on the hot press frame 29 and can be lifted. The hot pressing body 21 can be lifted by being driven by a hot pressing lifting device 219 which is a pneumatic cylinder or the like.

[0038] The continuous conveying device 3 comprises a positioning assembly 31 and a whole arrangement piece 32 which is provided with a whole arrangement groove 321; the positioning assembly 31 comprises a positioning fixed mold 311 and a cylindrical positioning lifting piece 312 which is arranged in the positioning fixed mold 311 and can be lifted, and the positioning fixed mold 311 is fixed on the output end of the whole arrangement piece 32. Usually, the bottom end of the positioning lifting piece 312 is connected with the output end of a positioning lifting device 319 which is a pneumatic cylinder or the like and can be lifted. The working principle of the hot pressing device 2 cooperating with the positioning assembly 31 to realize hot pressing is the same as that of the exhaust valve hot pressing device disclosed in the prior art CN220219930U, and details are not repeated here. It is easy to understand that the width of the whole arrangement groove 321 is approximately equal to the diameter of the exhaust valve rim 91, so that the exhaust valves 9 can be arranged in single row in the whole arrangement groove 321.

[0039] The whole arrangement piece 32 is fixedly provided with a pushing piece 329 which can move along the whole arrangement groove 321, and the pushing piece 329 pushes the exhaust valves 9 to reset, so that the exhaust valves 9 in the whole arrangement groove 321 can abut against each other and move towards the positioning assembly 31.

[0040] The whole arrangement piece 32 is provided with a transverse inlet 322, the output end of the exhaust valve output guide rail 15 communicates with the transverse inlet 322, and the exhaust valve output guide rail 15 can continuously convey the exhaust valves 9 in it into the whole arrangement groove 321 until the exhaust valves 9 in the exhaust valve output guide rail 15 abut against the side wall of the whole arrangement groove 321, but as mentioned above, the exhaust valves 9 in the exhaust valve output guide rail 15 have a tendency to move towards the whole arrangement groove 321 due to their own gravity.

[0041] The inner side wall of the whole arrangement groove 321 is provided with a blocking structure 323, such as a protrusion or a groove, which can abut against the exhaust valve rim 91 of the exhaust valve 9 to prevent the exhaust valve 9 from moving out of the whole arrangement groove 321. Figure 11As shown, the left and right inner side walls of the alignment groove 321 are provided with a blocking structure 323. Of course, the blocking structure 323 is provided at the bottom end face of the exhaust valve rim limiting body 328, or the inner wall of the low end of the alignment groove 321, which also belongs to the inner side wall of the alignment groove 321 being provided with the blocking structure 323; when the blocking structure 323 respectively abuts against the exhaust valve 9 in the alignment groove 321, the exhaust valve 9 is attached to the positioning lifting piece 312 in plan view (in other words, the exhaust valve 9 is tangent to the positioning lifting piece 312). Generally, for the exhaust valve 9 with the exhaust valve rim 91 and the exhaust valve body 92, the blocking structure 323 respectively abuts against the exhaust valve rim 91. Of course, the blocking structure 323 can also abut against the exhaust valve body 92.

[0042] The working principle is that the pushing piece 329 pushes the exhaust valve 9, and the exhaust valve 9 in the alignment groove 321 abuts in turn until the exhaust valve 9 closest to the positioning lifting piece 312 is stopped by the blocking structure 323; the pushing piece 329 continues to push the exhaust valve 9, and the exhaust valve 9 closest to the positioning lifting piece 312 passes through the blocking structure 323 due to its own elastic deformation or the elastic deformation of the blocking structure 323, until it is located above the positioning lifting piece 312 and coaxial with the positioning lifting piece 312 (positioned due to abutting against the positioning fixed mold 311), and then the positioning lifting piece 312 abuts against the exhaust valve 9 to lift it up, and the hot pressing body 21 is pressed down to realize hot pressing and then take out the exhaust valve 9. In the process of the exhaust valve 9 passing through the blocking structure 323, the elastic force generated when the exhaust valve 9 itself deforms elastically or the blocking structure 323 deforms elastically and resets makes the exhaust valve 9 move quickly towards the positioning lifting piece 312, which can ensure the positioning accuracy of the exhaust valve 9 on the positioning lifting piece 312 by abutting against the positioning fixed mold 311. Repeating the above process can realize continuous hot pressing of the exhaust valve 9.

[0043] As one of the specific embodiments, the blocking structure 323 is a cylindrical protrusion (the same shape in cross section, such as a triangular column, a square column, etc.) such as a semicylindrical shape (half of the cylindrical shape taken by a plane passing through the cylindrical axis), or the blocking structure 323 is a spring piece perpendicular to the side wall of the alignment groove 321.

[0044] As one of the specific embodiments, the top end of the alignment groove 321 is provided with the exhaust valve rim limiting body 328, and the blocking structure 323 is completely located in the exhaust valve rim limiting body 328 in plan view. This can prevent the exhaust valve 9 from jumping up when passing through the blocking structure 323, and ensure the positioning accuracy of the exhaust valve 9 on the positioning lifting piece 312.

[0045] As one of the specific embodiments, the alignment piece 32 includes an alignment base 324 and two alignment side frames 325 fixed on the alignment base 324, and the alignment base 324 and the alignment side frames 325 jointly form the alignment groove 321, and the anti-jumping blocking piece 326 is arranged on the side wall of the alignment side frame 325. This facilitates the assembly of the alignment piece 32.

[0046] As one of the specific embodiments, the positioning clamping groove 152 is arranged on the side of the aligning member 32, and the bottom end (i.e. the output end) of the exhaust valve output guide rail 15 is embedded in the positioning clamping groove 152 and faces the transverse inlet 322. The assembly and positioning between the exhaust valve output guide rail 15 and the aligning member 32 are facilitated.

[0047] As one of the specific embodiments, the side wall of the aligning groove 321 extends to form the anti-jumping stopper 326 towards the transverse inlet 322, the bottom end of the exhaust valve output guide rail 15 is provided with an extension body 151, the extension body 151 extends into the transverse inlet 322, the extension body 151 is provided with an inclined angle 153 and the lowest point thereof is lower than the anti-jumping stopper 326. The exhaust valve 9 closest to the aligning groove 321 in the exhaust valve output guide rail 15 can enter the aligning groove 321 in a slightly inclined posture, the anti-jumping stopper 326 prevents the exhaust valve 9 from being buckled and also prevents the exhaust valve 9 from being stuck by the anti-jumping stopper 326.

[0048] As one of the specific embodiments, the hot pressing device 2 comprises a hot pressing frame 29, the hot pressing frame 29 comprises a longitudinal beam 291, a transverse beam 292 and an adjusting beam 293, the longitudinal beam 291 is arranged longitudinally and is fixedly connected with the transverse beam 292 and the aligning member 32 at both ends, the hot pressing body 21 is arranged at one end of the adjusting beam 293, and the other end of the adjusting beam 293 is connected with the transverse beam 292 through a long hole. While ensuring the overall strength of the hot pressing frame 29, the position of the hot pressing body 21 is adjusted, so that the hot pressing body 21 is aligned with the positioning lifting member 312.

[0049] As one of the specific embodiments, the continuous conveying device 3 further comprises an electric control operation member 33, the electric control operation member 33 comprises a linear guide rail 332 and an operation push plate 331 sliding with the sliding end of the linear guide rail 332, the linear guide rail 332 is fixed on the aligning member 32, and the linear guide rail 332 is further provided with a sensor 333 electrically connected with the hot pressing device 2 and the continuous conveying device 3. The improved exhaust valve continuous hot pressing device can be operated more conveniently on the side of the aligning member 32 by pushing the operation push plate 331.
