[0002] Glassware is made of more than a dozen raw materials such as broken glass, soda ash, sodium nitrate, carbonated shells, quartz sand, etc. It is a container made through high-temperature melting and shaping processes. Glass products of different shapes can be produced according to different molds. The existing glassware forming machines can basically meet the daily use needs of industrial production, but there are still some shortcomings that need to be improved.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] See also Figure 1-8 An embodiment of the present invention provides an intermittent material transfer mechanism for an automatic glassware forming machine, comprising a base 1, a turntable 2 rotatably provided on the base 1, a plurality of molds 3 arranged circumferentially on the turntable 2, and a branch pipe 4 vertically provided on one side of the turntable 2, a nozzle 5 provided at the upper end of the branch pipe 4, a cooling station provided below the nozzle 5, and each mold 3 switches to the cooling station cyclically with the intermittent rotation of the turntable 2; a valve body assembly provided on the branch pipe 4, for controlling the spraying and stopping of the nozzle 5, and when there is a mold 3 at the cooling station, the nozzle 5 keeps spraying, and when there is no mold 3 at the cooling station, the nozzle 5 keeps stopping.

[0034] Specifically, the base 1 is used to support the turntable 2 and is integrated with a servo drive mechanism for controlling the intermittent rotation of the turntable 2; the edge of the turntable 2 is also provided with at least a receiving station for receiving molten glass raw materials, a pressing station for pressing the glass into shape, a shaping station for cooling the pressed glass products, and a material taking station for taking out the shaped glass products along the rotation direction of the turntable 2. The above stations, including the cooling stations, are evenly arranged on the turntable 2; the cooling stations are arranged before the receiving station and after the material taking station along the rotation direction of the turntable 2; the molds 3 are preferably 5-15, and the multiple molds 3 are evenly arranged on the turntable 2, and the arrangement spacing corresponds to the neat switching setting of each station. The branch pipe 4 is used to support the nozzle 5, which is suspended above the mold 3 and sprays downward. 1 to 3 cooling stations can be set adjacent to each other to meet different cooling requirements. The valve body assembly's control of the nozzle 5 is linked to the intermittent rotation of the turntable 2. When the turntable 2 drives the mold 3 to rotate to the cooling station and stays still for a period of time, the valve body assembly controls the nozzle 5 to keep spraying, and when the turntable 2 drives the mold 3 to rotate, the valve body assembly controls the nozzle 5 to keep stopping. In other words, the control action of the valve body assembly triggering the nozzle 5 to spray and stop is integrated with the rotation action of the turntable 2 that drives the mold 3 to rotate. In actual use of this technical solution, when the turntable 2 drives the mold 3 to move to the cooling station, the turntable 2 stops rotating for a period of time, and at this time the valve body assembly is linked to trigger the nozzle 5 to keep spraying to spray and cool the inside of the mold 3. Then the turntable 2 continues to rotate, so that the mold 3 leaves the cooling station, and the valve body assembly is linked to control the nozzle 5 to keep it stopped. This can avoid the waste caused by the uninterrupted spraying of the nozzle 5 and the wetting of the equipment, and can also accurately control the cooling process of the mold 3.

[0035] Compared with the prior art, the intermittent material transfer mechanism of the automatic glassware forming machine proposed in the embodiment of the present invention can control the spraying and stopping of the nozzle 5 by setting a valve body assembly, and is triggered respectively when the mold 3 enters or leaves the cooling station. This can avoid the waste caused by the uninterrupted spraying of the nozzle 5 and the wetting of the equipment, and can also accurately control the cooling process of the mold 3, thereby improving the practicality of the device.

[0036] As a preferred technical solution of this embodiment, the valve body assembly includes an interactive chamber 6 arranged in the branch pipe 4, a conduit 7 communicating with the interactive chamber 6 and used to connect to an external water source is provided at the upper end of the branch pipe 4, a piston column 8 is movably provided in the interactive chamber 6, and a support rod 9 is fixedly provided at the lower end of the piston column 8 to slide through the side wall of the branch pipe 4. The end of the support rod 9 is arranged in contact with the edge of the upper surface of the turntable 2, and a plurality of grooves 10 corresponding to each mold 3 are provided on the edge of the upper surface of the turntable 2. Specifically, the nozzle 5 is connected to the upper end side wall of the interactive chamber 6, and the conduit 7 is connected to the top of the interactive chamber 6; the piston column 8 is movable in the interactive chamber 6 to block the position where the nozzle 5 is connected to the interactive chamber 6, and After the piston column 8 descends, a part of the interactive cavity 6 of the conduit 7 limited by the piston column 8 is connected to the nozzle 5; the piston column 8 blocks the connection between the conduit 7 and the nozzle 5, corresponding to the support rod 9 being in contact with the upper surface of the turntable 2. When the piston column 8 descends to connect the conduit 7 and the nozzle 5, the support rod 9 moves down and embeds into the groove 10; the groove 10 is preferably V-shaped to meet the requirement that the conduit 7 automatically enters and exits the groove 10 when the turntable 2 rotates; the conduit 7 is connected to the external water source and maintains water pressure, and then when the support rod 9 corresponds to the groove 10, the water pressure forces the piston column 8 to descend, and the support rod 9 also descends and embeds into the groove 10, and the conduit 7 and the nozzle 5 are also connected.

[0037] In another embodiment of the present invention, a drain port 11 is provided at the bottom of the mold 3, and a plunger 12 is movably provided in the drain port 11. The plunger 12 has a first position and a second position in the lifting stroke. When the plunger 12 is in the first position, its upper end is flush with the inner bottom surface of the mold 3 and blocks the upper end of the drain port 11. When the plunger 12 is in the second position, the upper end of the drain port 11 is opened to discharge the water in the mold 3. Specifically, the drain port 11 is bucket-shaped, and the upper end of the plunger 12 is provided in a truncated cone shape that matches the drain port 11, and the two are wedge-shaped. Furthermore, the portion below the truncated cone shape of the upper end of the plunger 12 is cylindrical. And the inner diameter is smaller than the minimum inner diameter of the drain outlet 11, so that a gap is left between the main part of the plunger 12 and the drain outlet 11 for water to pass through; a leakage net is set at the lower end of the drain outlet 11 to keep it open downward, and support and guide the plunger 12 to perform lifting and lowering activities. The inner bottom surface of the turntable 2 is set as an inclined surface to guide the water flow toward the center. The center opening at the lower end of the turntable 2 and a gap are left between it and the base 1 to continue to discharge the water flow downward. A water storage tank for receiving the water flow is set on the base 1, and the water flow can be guided to discharge the equipment. The above drainage method is existing technology and will not be repeated; the height of the plunger 12 in the first position is lower than its height setting in the second position.

[0038] As a preferred technical solution of this embodiment, the switching of the plunger 12 between the first position and the second position is linked to the lifting and lowering movement of the support rod 9 when passing through the groove 10 through a linkage assembly. Specifically, when the support rod 9 enters the groove 10 and descends, the linkage plunger 12 switches from the first position to the second position. When the support rod 9 leaves the groove 10 and ascends, the linkage plunger 12 switches from the second position to the first position. In actual use, when the mold 3 is driven by the turntable 2 to correspond to the cooling station, on the one hand, the nozzle 5 is linked to keep spraying water to the inner wall of the mold 3 to cool it down through the above process. On the other hand, the plunger 12 is linked to the linkage assembly to switch from the first position to the second position, so that the drain port 11 is opened to discharge the water after cooling. When the mold 3 leaves the cooling station, the nozzle 5 stops and the plunger 12 is linked to descend from the second position and switches back to the first position, so that the drain port 11 is closed. The upper end of the plunger 12 is flush with the inner bottom surface of the mold 3, which facilitates the subsequent molding of glass products in the mold 3.

[0039] As the preferred technical solution of this embodiment, the linkage assembly includes a lifting groove 13 provided in the side wall entity of the turntable 2, and a linkage block 14 is elastically provided in the lifting groove 13. The upper end of the linkage block 14 extends into the groove 10, and the side wall is linked to the plunger 12 through a lever assembly. Specifically, the lever assembly includes a lever 15 hinged in the turntable 2, and the two ends of the lever 15 are hinged to the linkage block 14 and the plunger 12 respectively; when the linkage block 14 descends, the plunger 12 rises, and when the linkage block 14 rises, the plunger 12 descends; a first elastic member 24 is provided on the bottom surface of the lifting groove 13 to support the linkage block 14, and the first elastic member 24 can preferably be a spring. When the linkage block 14 is not subject to external force, the first elastic member 24 keeps pushing the linkage block 14 upward, thereby correspondingly maintaining the plunger 12 in the first position; when the support rod 9 enters the groove 10, it can press the linkage block 14. At this time, the water pressure borne by the support rod 9 through the piston column 8 is greater than the elastic force of the first elastic member 24.

[0040] In the above embodiment, when the support rod 9 leaves the groove 10, the linkage block 14 rises and resets under the elastic force, so that the nozzle 5 stops spraying and the plunger 12 returns to the first position to block the drain port 11. As a result, part of the water flow is retained in the mold 3, affecting the subsequent process. To address this problem, the following embodiment is proposed.

[0041] In another embodiment proposed by the present invention, a limiting component is provided on the linkage block 14 for limiting its own height to maintain the plunger 12 in the second position, and the cancellation of the limiting component occurs after the corresponding mold 3 leaves the cooling station for a certain distance. Specifically, the setting of the limiting component is that when the mold 3 corresponds to the cooling station, the linkage block 14 is pressed by the support rod 9, and then the linkage plunger 12 rises and switches to the second position, and the linkage block 14 descends to the corresponding height and is limited, thereby maintaining the second position of the plunger 12. Subsequently, when the mold 3 leaves the cooling station, the linkage block 14 is canceled. Remove the support rod 9 and press it, but still maintain the height to keep the plunger 12 in the second position until the mold 3 leaves one end of the cooling station. The limit assembly cancels the limit, the linkage block 14 elastically rises, and the plunger 12 also links to switch back to the first position. As a result, the closing of the drain outlet 11 is delayed compared to the stop of the nozzle 5, so that the water flow in the mold 3 that is not discharged in time has sufficient time to be discharged, avoiding being retained in the mold 3; further, under the effect of this delay, the acceleration and centrifugal force generated when the turntable 2 rotates again can also prevent water droplets from being retained on the upper end of the plunger 12.

[0042] As a preferred technical solution of the embodiment of the present invention, the limit assembly includes a limit column 16 elastically arranged on the linkage block 14, one end of the limit column 16 movably penetrates the side wall of the linkage block 14 away from the plunger 12, and a ring body 17 is elastically rotated in the turntable 2. The inner wall of the ring body 17 is provided with a limit groove 18 matching the limit column 16, and a retractable lever 19 is provided on the ring body 17. The lever 19 moves upward and penetrates the upper surface of the turntable 2 and is in the active stroke of the support rod 9. When the lever 19 is pushed by the support rod 9, it continuously descends to It does not hinder the height of the support rod 9. Specifically, the linkage block 14 is fitted on the inner side of the ring body 17; the movable direction of the limiting column 16 is set along the radial direction of the turntable 2, and a spring groove is provided on the linkage block 14. A second elastic member 25 is provided in the spring groove to connect the limiting column 16. When the limiting column 16 does not correspond to the limiting groove 18, the limiting column 16 is against the inner wall of the ring body 17 so that the second elastic member 25 maintains the compressed stored elastic potential energy; the limiting groove 18 is formed in a concave shape on the inner wall of the ring body 17, and its two ends are set along the circumferential direction of the ring body 17, limiting One end of the positioning groove 18 is gradually recessed toward the other end to transition to the inner wall of the ring body 17; a slider is provided on the inner side of the ring body 17, and a slide groove matching the slider is provided in the turntable 2 entity. A third elastic member 26 is provided in the slide groove. The third elastic member 26 maintains the ring body 17 in a static state without external force. In this state of the ring body 17, the linkage block 14 descends and drives the limiting post 16 to correspond to the deepest end of the limiting groove 18. At this time, the limiting post 16 is embedded in the limiting groove 18 to limit the movement of the linkage block 14; The limiting groove 18 is wedge-shapedly matched with the limiting column 16; a vertical socket is provided on the ring body 17, and the lower end of the shift rod 19 remains movably inserted into the socket; a sliding pin 20 is provided on the side wall of the shift rod 19, and an inclined slot 21 matching the sliding pin 20 is provided on the side wall of the turntable 2; while the shift rod 19 rotates synchronously with the ring body 17 around the axis of the turntable 2, the sliding pin 20 interacts with the inclined slot 21 to make the shift rod 19 rise and fall, and the direction in which the shift rod 19 is pushed by the support rod 9 is the direction of resisting the elastic force of the third elastic member 26 on the ring body 17.In actual use of this technical solution, when the turntable 2 rotates to drive the mold 3 to correspond to the cooling station, the support rod 9 enters the groove 10 to press the linkage block 14, and the linkage block 14 descends to switch the plunger 12 to the second position, and the linkage block 14 drives the limiting column 16 to descend to correspond to the limiting groove 18, and the limiting column 16 elastically extends out and embeds into the limiting groove 18, thereby limiting the linkage block 14 and also limiting the plunger 12 to the second position; after that, the turntable 2 rotates again, driving the mold 3 to leave the cooling station, and the support rod 9 also leaves the groove 10 to cancel pressing the linkage block 14, but the linkage block 14 cannot rise immediately due to the limit, and then, as the rotation of the turntable 2 continues, the support rod 9 fits the turntable 2 The upper surface slides to approach and begin to push the lever 19, and the lever 19 drives the ring body 17 to rotate relative to the turntable 2, and the limit groove 18 on the inner side of the ring body 17 forces the limit column 16 to slowly disengage from the limit groove 18 through wedge cooperation. At the same time, the lever 19 slowly descends by virtue of the action of the sliding pin 20 and the inclined slide groove 21. Finally, the limit column 16 disengages from the limit groove 18 to cancel the limit on the linkage block 14, the linkage block 14 rises, and the plunger 12 also switches from the second position to the first position. In addition, the support rod 9 also passes smoothly from the top of the lever 19 that has been retracted to the corresponding height, and then the ring body 17 rotates again under the elastic force, so that the limit groove 18 and the lever 19 also return to the initial position.

[0043] As a preferred technical solution of the above embodiment, a cantilever 22 fixed to the base 1 is provided in the turntable 2, and the end of the cantilever 22 corresponds to the bottom where the plunger 12 passes and is provided with a guide slope 23. When the plunger 12 passes the guide slope 23, it is forced to lift up. Specifically, the edge of the guide slope 23 is chamfered, and the lower end of the passing plunger 12 can be wedge-shaped and squeezed to force the plunger 12 to rise; when the plunger 12 corresponds to the guide slope 23, the mold 3 corresponding to the plunger 12 is located at a station between the shaping station and the material taking station, which is preferably a demolding station. At this time, the lifting of the plunger 12 triggered by the guide slope 23 can lift the glass product just shaped in the mold 3 to a certain height to help demolding, thereby facilitating the subsequent material taking process.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
