Description

Technical Field

[0001] This invention relates to the field of glassware manufacturing technology, specifically to an automatic centering turntable mechanism and a glassware transfer and forming press. Background Technology

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

[0003] Patent document CN114075030A, published on February 22, 2022, discloses a rapid prototyping device for glassware and its prototyping process, specifically relating to the field of glassware processing technology. The device includes a support plate with a bearing on its upper surface. The inner wall of the bearing is sleeved with the outer surface of a rotating shaft, and the bottom end of the rotating shaft is fixedly connected to the upper surface of a first rotating plate. This invention achieves clamping contact between two templates by setting up a first rotating plate, a second rotating plate, a drive assembly, a connecting rod, a connecting hole, a placement plate, a support pad, a moving rod, and templates. At this time, the glassware can be fed and formed in a mold composed of the two templates and a bottom plate. After the moving wheel separates from the support pad, the moving plate moves downward, and the two templates automatically separate from the formed glassware, reducing the probability of damage during glassware clamping and removal. This ensures a smooth and efficient process for feeding, forming, and removing the glassware, and to a certain extent, guarantees a more ideal overall processing efficiency and effect.

[0004] In the prior art of the aforementioned patent, after the glassware is pressed and formed, it needs to be reheated to eliminate stress and reduce the risk of cracking. However, during this process, the glassware is removed from the mold and moves on a rotating tray, making it difficult to center. It may also deviate further from the center position due to centrifugal force, which can easily cause uneven heating. Therefore, there is an urgent need for an automatic centering turntable mechanism and a glassware transfer and forming press to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic centering turntable mechanism and a glassware transfer forming press to overcome the above-mentioned shortcomings in the prior art.

The mechanism also includes: an edge-adhesive component, of which multiple components are evenly arranged circumferentially on the trays and rotatably mounted on the trays. During its rotation stroke, the edge-adhesive component has a first position where it is retracted into the tray and a second position where it is tilted upward and extends out of the tray. A linkage component is used to link the rotation of the trays and the rotation of the edge-adhesive component. During the process of the turntable carrying the trays to rotate into the heating zone, the edge-adhesive component switches back and forth between the first position and the second position once.

[0008] Preferably, a sleeve is coaxially connected to the lower end of the tray, and the lower end of the sleeve is rotatably connected to the turntable.

[0009] Preferably, the linkage component includes a rotating block rotatably disposed within the tray and a slidably disposed rack. The rotating block is provided with a first sliding groove, and the rack is connected with a first sliding pin movably connected to the first sliding groove.

The rotation of the rotating block is linked to the rotation of the turntable relative to the rotating seat through the spiral assembly.

[0010] Preferably, the spiral assembly includes an abutment sleeve that is elastically and dynamically movable at the lower end of the sleeve column and a rotating rod coaxially connected to the rotating block. The lower end of the rotating rod is coaxially inserted into the abutment sleeve and a sliding protrusion is provided on the outer wall. A spiral groove matching the sliding protrusion is provided on the inner side of the abutment sleeve. A first lifting platform matching the wedge shape of the abutment sleeve is provided on the side of the rotating seat near the heating zone.

[0011] Preferably, the heating zone is provided with a bottom firing station. When the turntable carries the tray to the bottom firing station, the edge-attaching part is kept in the second position and moved and tightened towards the center of the tray. At the same time, the edge-attaching part is wedge-shapedly pressed against the bottom of the glassware on the tray.

[0012] Preferably, the tray is provided with a connecting seat, one end of the edge-attaching part is rotatably connected to the connecting seat and can be slidably arranged laterally, the connecting seat is provided with an elastic component to prevent the edge-attaching part from sliding, the rotating seat is provided with a second lifting platform that matches the wedge shape of the abutment sleeve at the position corresponding to the bottom firing station, the rotating shaft of the edge-attaching part is provided with a locking block, and the connecting seat is provided with a protruding edge that limits the rotation of the locking block.

[0013] Preferably, the connecting seat is slidably disposed within the tray, and the tray is provided with an adjustment component for controlling the movement of the connecting seat. The rack is connected to the first sliding pin through a sleeve that is movably sleeved on the outside, and the sleeve is provided with a clamping component for limiting the relative movement of the rack.

[0014] Preferably, the adjusting assembly includes a ring body rotatably disposed within the tray, the ring body being provided with a second sliding groove, the bottom of the connecting seat being provided with a second sliding pin matching the second sliding groove, an adjusting screw being threadedly disposed on the side wall of the tray, a bevel gear being synchronously disposed at one end of the adjusting screw extending into the tray, and a bevel gear ring being disposed on the outer wall of the ring body engaging with the bevel gear.

A clutch is mounted on the drive wheel, and the clutch intermittently locks the relative position between the turntable and the drive wheel.

[0017] In the above technical solution, the beneficial effects of the present invention are:

[0018] This automatic centering turntable mechanism uses multiple edge-adhesive components. Under the action of the linkage components, when any tray enters the heating zone with the turntable, the edge-adhesive components rotate in conjunction. First, they switch from a first position to a second position, that is, each edge-adhesive component pushes the corresponding side of the glassware on the tray from the circumferential direction to automatically center the glassware. Then, the edge-adhesive components switch back from the second position to the first position so as not to affect the subsequent transfer of glassware. This ensures that the glassware is automatically centered and that the heating is uniform.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0037] Please see Figure 1-12 An automatic centering turntable mechanism provided in this embodiment of the invention includes a turntable 2 rotatably connected to a rotating base 1 and multiple trays 3 arranged circumferentially on the turntable 2. A heating zone is provided on one side of the turntable 2. The turntable 2 rotates to carry each tray 3 sequentially through the heating zone. The mechanism also includes: an edge-adhesive member 4, which is evenly arranged in multiple pieces on the circumference of the trays 3 and rotatably mounted on the trays 3. During its rotation stroke, the edge-adhesive member 4 has a first position where it is retracted into the tray 3 and a second position where it is tilted upward and extends out of the tray 3; and a linkage component, which is used to link the rotation of the trays 3 and the rotation of the edge-adhesive member 4. During the process of the turntable 2 carrying the trays 3 to rotate into the heating zone, the edge-adhesive member 4 switches back and forth between the first position and the second position once.

[0038] Specifically, the turntable 2 rotates intermittently on the rotating base 1, and the angle of each rotation is consistent with the angle of the multiple trays 3 changing sequentially; the trays 3 are preferably 10-20, evenly arranged around the circumference; the heating zone is surrounded by an arc-shaped guard plate set on the outer side of the turntable 2, and the heating zone is arranged sequentially with a firing port station and a firing bottom station along the intermittent movement direction of the trays 3. At the firing port station on the inner wall of the heating zone, a flame nozzle is set pointing to the height of the upper opening of the glassware carried on the tray 3, and at the firing bottom station on the inner wall of the heating zone, a flame nozzle is set pointing to the height of the lower base of the glassware carried on the tray 3; at least a feeding station and a discharging station are also set in the circulation trajectory of the trays 3, with the feeding station set before entering the heating zone and the discharging station set after leaving the heating zone. The edge-attaching element 4 is preferably rod-shaped or plate-shaped; the number of edge-attaching elements 4 on the same tray 3 is not less than 3; the upper surface of the tray 3 is provided with a through groove for the edge-attaching element 4 to be stored and extended; the free end of the edge-attaching element 4 during rotation is always arranged radially along the tray 3; the edge-attaching element 4 is in the first position, and its whole body does not protrude above the upper surface of the tray 3; the edge-attaching element 4 is in the second position, and the diameter of the circle formed by the position where each edge-attaching element 4 contacts the glassware is consistent with the outer diameter of the corresponding height of the glassware; under the action of the linkage component, each edge-attaching element 4 rotates synchronously, and the rotation angle is consistent; the function of the linkage component is to control the rotation of the edge-attaching element 4, and during the process of the turntable 2 carrying the tray 3 to rotate into the heating zone, the edge-attaching element 4 is controlled to first switch from the first position to the second position, and then switch back from the second position to the first position, completing one switching back and forth. In practical use, the turntable 2 rotates to carry any tray 3 into the heating zone. Then, under the action of the linkage component, the edge-attaching parts 4 first switch from the first position to the second position. That is, each edge-attaching part 4 pushes the corresponding side of the glassware on the tray 3 from the circumferential direction to make the glassware automatically center. Then, the edge-attaching parts 4 switch back from the second position to the first position so as not to affect the subsequent transfer of glassware. This ensures that the glassware is automatically centered and that the heating is uniform.

[0039] Compared with the prior art, the automatic centering turntable mechanism proposed in this embodiment of the invention is provided with multiple edge-adhering parts 4. Under the action of the linkage component, when any tray 3 enters the heating zone with the turntable 2, the edge-adhering parts 4 rotate in linkage and first switch from the first position to the second position. That is, each edge-adhering part 4 pushes the corresponding side of the glassware on the tray 3 from the circumferential direction to make the glassware automatically center. Then the edge-adhering parts 4 switch back from the second position to the first position so as not to affect the subsequent transfer of glassware. The above ensures that the glassware is automatically centered and that the heating is uniform.

[0040] As a preferred technical solution in this embodiment, a sleeve 5 is coaxially connected to the lower end of the tray 3. The lower end of the sleeve 5 is rotatably connected to the turntable 2. Specifically, the sleeve 5 supports the tray 3, and the lower end of the sleeve 5 rotatably penetrates the upper end of the turntable 2. Limits are set at both the upper and lower penetration positions, thereby ensuring the height of the sleeve 5 and its stable rotation.

[0041] As a preferred embodiment, the linkage component includes a rotating block 6 rotatably disposed within the tray 3 and a slidably disposed rack 7. The rotating block 6 is provided with a first sliding groove 8, and the rack 7 is connected to a first sliding pin 9 movably connected to the first sliding groove 8. The rotating shaft of the edge piece 4 is coaxially connected to a gear 10 meshing with the rack 7. The rotation of the rotating block 6 is linked to the rotation of the turntable 2 relative to the rotating seat 1 through the spiral assembly. Specifically, the rotating block 6 is preferably in the shape of a circular plate and is coaxially disposed with the tray 3. The inner top surface of the tray 3 is provided with a groove for the rack 7 to move, and the direction of movement of the rack 7 is parallel to the radial direction of the tray 3. The two ends of the first sliding groove 8 are set at a certain angle to the line connecting the center of the rotating block 6, and there is a length difference between the two connecting lines. Thus, under the rotation of the rotating block 6, the first sliding groove 8... The sliding groove 8 moves relative to the first sliding pin 9 to allow the rack 7 to move smoothly closer to or away from the center of the rotating block 6; the axis of rotation of the edge-attaching part 4 is perpendicular to the direction of movement of the rack 7; the gear 10 is located on the lower side of the rack 7; the spiral assembly is triggered at a designated position; when the spiral assembly is triggered, for example, when the turntable 2 rotates relative to the rotating seat 1 to carry any tray 3 into the heating zone, the rotating block 6 rotates in conjunction, and then the rack 7 moves in conjunction with the first sliding groove 8 and the first sliding pin 9. The rack 7 first moves closer to the center of the rotating block 6, and then the gear 10 is driven to make the edge-attaching part 4 rotate upward from the first position to the second position. Then, the rack 7 moves away from the center of the rotating block 6, and then the gear 10 is driven to make the edge-attaching part 4 rotate downward from the first position back to the second position.

[0042] As a preferred embodiment, the spiral assembly includes an abutment sleeve 11 elastically movable at the lower end of the sleeve 5 and a rotating rod 12 coaxially connected to the rotating block 6. The lower end of the rotating rod 12 is coaxially inserted into the abutment sleeve 11 and has a sliding protrusion 13 on its outer wall. The inner side of the abutment sleeve 11 has a spiral groove 14 matching the sliding protrusion 13. The rotating seat 1 has a first lifting platform 15 that wedges with the abutment sleeve 11 on the side near the heating zone. Specifically, the lower end of the sleeve 5 has a cavity that matches the abutment sleeve 11. The top surface of the cavity is provided with a spring connecting the abutment sleeve 11. The lower end of the abutment sleeve 11 is spherical or has rounded edges. A key block is fixedly provided on the outer wall of the abutment sleeve 11, and a keyway matching the key block is provided on the inner wall of the cavity. This limits the abutment sleeve 11 to only move axially relative to the sleeve 5. The rotating rod 12 coaxially passes through the sleeve 5 and its upper end is connected to the rotating block 6. The coaxial fixed connection; the elastic force on the abutment sleeve 11 keeps it extending downwards to the longest position of the sleeve post 5, and the rotation position of the corresponding rotating block 6 is such that the rack 7 is at the end farther from the center of the rotating block 6 during the active stroke; the rotation direction of the spiral groove 14 is set so that when the abutment sleeve 11 rises relative to the sleeve post 5, the rotation direction of the rotating block 6 is linked to the movement of the rack 7 to move closer to the center of the rotating block 6, and conversely, when the abutment sleeve 11 falls relative to the sleeve post 5, the rotation direction of the rotating block 6 is linked to the movement of the rack 7 to move away from the center of the rotating block 6; the first lifting platform 15 is set directly below the trajectory of the abutment sleeve 11 as it rotates with the turntable 2, and the first lifting platform 15 extends in an arc shape with the center of the turntable 2 as the center, and the two ends of the extension are sloped. The maximum height of the first lifting platform 15 is such that after it abuts against the abutment sleeve 11, it triggers the edge-attaching part 4 to switch from the first position to the second position. In practical use, as the turntable 2 rotates to carry any tray 3 into the heating zone, the corresponding abutment sleeve 11 on the lower side of the tray 3 begins to abut against the first lifting platform 15. Thus, the abutment sleeve 11 rises relative to the sleeve post 5, thereby causing the rotating block 6 to rotate, making the rack 7 move closer to the center of the rotating block 6. This, in turn, causes the edge-attaching component 4 to rotate from the first position to the second position. When the abutment sleeve 11 abuts against the highest point of the first lifting platform 15, the edge-attaching component 4 is in the second position. After that, the abutment sleeve 11 descends relative to the sleeve post 5. Thus, according to the above principle, the edge-attaching component 4 switches back from the second position to the first position. This achieves the automatic centering function of the edge-attaching component 4 for the glassware on the tray 3.

[0043] In another embodiment of the present invention, a bottom-firing station is provided in the heating zone. When the turntable 2 carries the tray 3 to the bottom-firing station, the edge-attaching piece 4 maintains the second position and moves and tightens towards the center of the tray 3. At the same time, the edge-attaching piece 4 and the bottom of the glassware on the tray 3 are wedge-shaped and pressed together. Specifically, in actual production, the tray 3 supports the glassware, which makes the bottom of the glassware blocked and difficult to reheat. The prior art uses a hollowed-out design for the tray 3, but the heating effect is still not obvious, and the heating time is often extended, which affects the product quality of the glassware. This embodiment is proposed to solve this problem. When the edge-attaching piece 4 is in the second position, it tilts upward and curves outward toward the outside of the tray 3, thereby contacting the bottom edge of the glassware through its tilted upper surface. When the tray 3 is in the firing position, each edge-attaching piece 4 maintains the second position and moves and tightens toward the center of the tray 3 simultaneously. The bottom of the glassware is pushed by a wedge-shaped compression, which can lift the glassware on the tray 3 to a certain height, causing the base to be suspended. This allows flame to be sprayed into the space to directly and fully heat the base of the glassware, greatly improving efficiency.

[0044] As a preferred embodiment, a connecting seat 16 is provided inside the tray 3. One end of the edge-attaching piece 4 is rotatably connected to the connecting seat 16 and can slide laterally. An elastic component is provided inside the connecting seat 16 to prevent the edge-attaching piece 4 from sliding. A second lifting platform 17 that matches the wedge shape of the abutment sleeve 11 is provided on the rotating seat 1 at the position corresponding to the bottom-burning station. A locking block 18 is provided on the rotating shaft of the edge-attaching piece 4. A protruding edge 19 that limits the rotation of the locking block 18 is provided on the connecting seat 16. Specifically, the connecting seat 16 is box-shaped, with the upper end... The corner away from the rotating block 6 is open, and the side wall of this side is provided with a waist-shaped hole. The rotating shaft of the edge piece 4 is movably connected to the waist-shaped hole. The elastic component includes a spring and a push block disposed in the connecting seat 16. The push block is disposed on the side close to the edge piece 4, and the spring is disposed on the other side of the push block and keeps pushing the push block, thereby keeping the edge piece 4 at the end of the connecting seat 16 away from the rotating block 6 without external force. The gear 10 and the locking block 18 are respectively located at both ends of the rotating shaft of the edge piece 4 and are located outside the connecting seat 16. The extension direction of component 8 forms a certain angle with the extension direction of component 4, but is less than 90°; when component 4 switches from the first position to the second position, the locking block 18 approaches the protruding edge 19 to limit component 4 to the second position. Then, when the rack 7 continues to move closer to the rotating block 6, it can pull the gear 10 to move component 4 closer to the center of the rotating block 6, while the elastic component is compressed by force; the maximum height of the second lifting platform 17 is higher than the maximum height of the first lifting platform 15, and the second lifting platform 17 is also the center of the turntable 2. The center is an arc shape with slopes at both ends. Furthermore, the maximum height of the second lifting platform 17 is set radially towards the firing position along the turntable 2. Thus, when the turntable 2 stops intermittently, and the tray 3 is facing the firing position, the abutting sleeve 11 corresponding to the tray 3 remains at the highest position of the second lifting platform 17. This maintains the state of the edge-attaching piece 4 lifting the glassware, so as to ensure that the glassware is fully fired at the firing position. Afterwards, when the turntable 2 rotates again, the edge-attaching piece 4 can be reset.

[0045] In another embodiment of the present invention, the connecting seat 16 is slidably disposed within the tray 3. An adjusting component for controlling the movement of the connecting seat 16 is disposed within the tray 3. The rack 7 is connected to the first sliding pin 9 via a sleeve 20 movably fitted on its outer side. A clamping component for limiting the relative movement of the rack 7 is disposed on the sleeve 20. Specifically, in actual production, glassware exists in different sizes. This embodiment is proposed to adapt to the production of different glassware. The sliding direction of the connecting seat 16 is consistent with the sliding direction of the rack 7. The clamping component is used to lock or unlock the relative position of the rack 7 and the sleeve 20. When the clamping component is locked, since the rack 7 and the gear 10 remain engaged, the rack 7 moves simultaneously as the adjusting component adjusts the position of the connecting seat 16. Then, the clamping component re-locks the position between the rack 7 and the sleeve 20, thus achieving the adjustment of the position of the connecting seat 16, which is also the adjustment of the position of the edge piece 4. Furthermore, the follow-up movement of the rack 7 achieves stepless adjustment. The adjusting component controls the synchronous movement of each connecting seat 16.

[0046] As a preferred technical solution in this embodiment, the adjusting component includes a ring 21 rotatably disposed within the tray 3, a second sliding groove 22 disposed on the ring 21, a second sliding pin 23 matching the second sliding groove 22 disposed at the bottom of the connecting seat 16, an adjusting screw 24 rotatably disposed on the side wall of the tray 3, a bevel gear 25 rotatably disposed at one end of the adjusting screw 24 extending into the tray 3, and a bevel ring 26 meshing with the bevel gear 25 disposed on the outer wall of the ring 21. Specifically, the ring 21 is sleeved on the outside of the rotating block 6; the two ends of the second sliding groove 22 are set at a certain angle to the center line of the ring 21, and there is a length difference between the two connecting lines, thus, in As the ring 21 rotates, the second sliding groove 22 moves relative to the second sliding pin 23, so that the connecting seat 16 can move smoothly closer to or away from the center of the ring 21. One end of the adjusting screw 24 extends out of the outer wall of the tray 3, and this end is provided with a scale for easy observation. The other end of the adjusting screw 24 is preferably in the shape of a cross column or a polygonal column, and a sleeve coaxially connected to the bevel gear 25 is sleeved on the outside, so that the rotation of the bevel gear 25 is synchronized with the adjusting screw 24 and does not affect the threaded feed movement of the adjusting screw 24. In addition, the threaded feed action of the adjusting screw 24 adjusts its length extending out of the tray 3, and the adjustment size can be easily known by its surface scale.

[0047] As a preferred technical solution of this embodiment, the clamping assembly includes a threaded hole provided in the first sliding pin 9, and a clamping screw 27 is threaded into the threaded hole. One end of the threaded hole is connected to the inside of the kit 20. The lower end of the clamping screw 27 extends movably out of the bottom surface of the tray 3. Specifically, another through groove is provided at the bottom of the tray 3 for the clamping screw 27 to move through. The clamping screw 27 clamps the rack 7 part in the kit 20 through the threaded feed action, thereby restricting the relative movement between the rack 7 and the kit 20. Conversely, after the clamping screw 27 is loosened, the rack 7 can move relative to the kit 20.

[0048] A glassware transfer forming press includes an automatic centering turntable mechanism and a rotating base 1. A drive wheel 28 is rotatably mounted on the rotating base 1 to drive each tray 3 to rotate. A clutch 29 is mounted on the drive wheel 28. The clutch 29 intermittently locks the relative position of the turntable 2 and the drive wheel 28. Specifically, the drive wheel 28 is controlled to rotate by a servo system. A driven wheel connected to the drive wheel 28 is mounted on the sleeve 5 at the lower end of each tray 3. The clutch 29 is intermittently engaged or disengaged by the servo system. When the clutch 29 is engaged, the turntable 2 rotates with the drive wheel 28, thus carrying each tray 3 in a stepwise motion. When the clutch 29 is disengaged, the turntable 2 stops due to rotational damping, while the drive wheel 28 drives each tray 3 to rotate. The specific working principle described above is existing technology and will not be elaborated further.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
