[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] See also Figure 1-7The embodiment of the present invention provides a preheating device for producing tempered glass containers, comprising:

[0034] Ring conveyor line 1;

[0035] The clamp assembly 4 can be displaced along the annular conveyor line 1; a first area section, a second area section, and a third area section are sequentially provided in the moving stroke of the clamp assembly 4;

[0036] In the first area, the glass body 6 is placed on the fixture assembly 4 by the first robot 3;

[0037] The flamethrower 5 heats the end of the glass body 6 when the glass body 6 is displaced in the second section, and the clamp assembly 4 centers the glass body 6 and drives it to rotate.

[0038] The second manipulator 2, in the third area, docks the glass base with the glass body 6 by the second manipulator 2 to form a complete glass container;

[0039] When the glass container moves to the first area, the clamp assembly 4 is unlocked, and the glass container is unloaded by the first manipulator 3 .

[0040] In the embodiment of the present invention, the ring conveyor line 1 is composed of a chain and a sprocket, which can drive the clamp assembly 4 to move along a specific route;

[0041] In the first section, the first manipulator 3 can grab the glass body 6 and place it on the clamp assembly 4. As the circular conveyor line 1 conveys the glass body 6, it enters the second section. At this time, the clamp assembly 4 passively clamps and positions the glass body 6. The flame mouth of the flamethrower 5 is aligned with the end of the glass body 6. The flame heats the glass body 6. During the movement of the glass body 6, the clamp assembly 4 also drives the glass body 6 to rotate. In this way, by arranging the flamethrower 5 on one side of the glass body 6, an annular heating of the glass body 6 can be achieved, so that the cup mouth of the glass body 6 melts evenly.

[0042] As the glass body 6 is transported by the circular conveyor line 1, it enters the third area. After entering the third area, the second robot 2 grabs the glass base and connects the glass base to the glass body 6. Since the upper part of the glass body 6 is in a melted state, the glass body 6 and the glass base will be connected together.

[0043] As the circular conveyor line 1 conveys, the glass container consisting of a glass base and a glass body 6 moves to the first area section. A rotary unit is provided in the first area section. The rotary unit drives the clamp assembly 4 to unlock, and the first robot 3 will grab the glass container to separate the glass container from the clamp assembly 4. Also in this area, the first robot 3 will re-clamp a new glass body 6 and place it on the clamp assembly 4. This device continuously conveys the glass body 6 and preheats the glass body during the conveying process to reduce the waiting time of the robot, thereby greatly improving the equipment utilization rate, changing the single-station intermittent production to circular continuous conveying, reducing the waiting time of the robot, and improving the equipment utilization rate by more than 50%.

[0044] Compared with the existing single-station heating, in order to improve efficiency and shorten the heating time, the flame temperature is higher, but the glass has poor thermal conductivity, the local temperature rises too quickly, thermal stress is easily generated, and cracks are easily generated. The present invention increases the time required for heating while improving efficiency, and the temperature rises less per unit time, so as to form a temperature ladder in the glass body 6. Passive self-rotation heating replaces fixed-station heating, and the heating uniformity is improved by 40%, and the defective rate is reduced to below 0.1%.

[0045] In the embodiments of the present invention, please refer to Figure 1 The travel route of the annular conveyor line 1 can be set to any one of circular, rectangular, elliptical and triangular shapes.

[0046] The travel route of the glass body 6 transported by the annular conveyor line 1 can be any one of circular, rectangular, elliptical, and triangular. Corresponding structures are set in the areas along the way to achieve the functions achieved by the present invention. The fire protection settings of the annular conveyor line 1 and the selection of the corresponding driving source are well-known technologies in the technical field and will not be elaborated here.

[0047] In the embodiments of the present invention, please refer to Figure 1 The flamethrower 5 is arranged along the moving path of the glass body 6, and its flame temperature is greater than 650℃.

[0048] The flamethrower 5 consists of a nozzle and a nozzle. The nozzle is arranged along the axial direction of the nozzle, and the axial direction of the nozzle is arranged along the moving direction of the glass body 6. In this way, during the advancement of the glass body 6, the flame ejected by the nozzle can heat the upper port of the glass body 6, so that the upper part of the glass body 6 is melted, which is convenient for the connection of the glass base. The fuel and flame intensity of the flamethrower are set according to actual needs, which belongs to the well-known technology in this technical field and will not be repeated here.

[0049] In the embodiments of the present invention, please refer to Figure 1 and Figure 2The clamp assembly 4 includes a rotating part and a self-locking assembly 47. During the movement of the glass body 6, the rotating part rotates around itself. In the initial stage of rotation, the self-locking assembly 47 is synchronously driven to expand. The self-locking assembly 47 squeezes the inner wall of the glass body 6 to center the glass body 6 and rotate it.

[0050] During the conveying process of the annular conveyor line 1, the clamp assembly 4 is in the second area segment. At this time, the rotating part will rotate, and the self-locking assembly 47 will be driven to expand during the rotation. Since the glass body 6 is covered on the outside of the clamp assembly 4, the self-locking assembly 47 will inevitably be squeezed on the inner wall of the glass body 6 during the expansion process. In this way, the glass body 6 is centered and clamped by the self-locking assembly 47 to facilitate the subsequent installation of the glass base, and is squeezed on the glass body 6 by the self-locking assembly 47. In this way, the glass body 6 will be driven to rotate together, and the flamethrower 5 will evenly heat the end of the glass body 6 during the rotation.

[0051] In the embodiments of the present invention, please refer to 1 and Figure 2 The rotating part includes a side plate 41, a support plate 42, an inclined plate 43, a connecting plate 44, a base 45, a rotating sleeve 46, a gear 461, and a rack 462. The connecting plate 44 is fixedly connected to the circular conveyor line 1, the base 45 is fixedly mounted on the connecting plate 44, the rotating sleeve 46 is rotatably connected to the base 45, the gear 461 is fixedly sleeved on the rotating sleeve 46, and the rack 462 is set on the rotation path of the gear 461. The side plate 41 is fixedly mounted on the base 45, the support plate 42 is fixedly mounted on the upper part of the side plate 41, and the inclined plate 43 is mounted on one side of the support plate 42. The upper end of the rotating sleeve 46 passes through the support plate 42, and the support plate 42 is above the gear 461.

[0052] The connecting plate 44 is fixedly connected to the chain of the circular conveyor line 1. Therefore, during the operation of the circular conveyor line 1, the movement of the chain drives the movement of the connecting plate 44, and the rack 462 is fixed to the frame of the circular conveyor line 1, and the rack 462 is always fixed. Therefore, during the operation of the circular conveyor line 1, the connecting plate 44 drives the base 45 to move, and when the base 45 is displaced along the length direction of the rack 462, the gear 461 is engaged with the rack 462 at this time, so that the gear 461 will rotate, and the gear 461 is fixed on the rotating sleeve 46, so the rotating sleeve 46 will rotate, and the side plate 41 is fixedly installed on the base 45. Therefore, the side plate 41, the support plate 42 and the inclined plate 43 will migrate synchronously with the base 45, and the support plate 42 is above the gear 461, so that the glass body 6 can be supported by the support plate 42 to ensure that after the first manipulator 6 places the glass body 6, the glass body 6 can stably follow the clamp assembly 4 to move forward.

[0053] The rotary unit 7 is used to drive the gear 461 to reverse. When the glass body 1 moves one circle and needs to be unloaded, the rotary unit 7 drives the gear 461 to reverse to achieve the retraction of the self-locking component 47, so that the glass container can be removed smoothly.

[0054] In the embodiments of the present invention, please refer to Figure 2-7 The base 45 is formed by splicing a first splicing block 451 and a second splicing block 452 together.

[0055] The self-locking assembly 47 includes a transmission shaft 471, a linkage 472, a screw rod 473, a sliding member 474, an elastic member 475, and a fitting member 48. The elastic member 475 is rotatably connected in the first splicing block 451. The transmission shaft 471 is fixedly mounted on the elastic member 475. A pair of sliding members 474 are slidably connected to the upper sides of the rotating sleeve 46. The two ends of the screw rod 473 are respectively threadedly connected to a pair of sliding members 474. The fitting member 48 is fixed on the sliding member 474. The transmission shaft 471 and the screw rod 473 are transmission-connected via the linkage 472.

[0056] The base 45 adopts a split design to facilitate the installation of the rotating sleeve 46 and the elastic member 475;

[0057] When the gear 461 is initially in contact with the rack 462, the elastic member 475 cannot rotate at this time due to a certain resistance between the elastic member 475 and the first splicing block 451. However, since the rotating sleeve 46 will inevitably rotate at this time, when the rotating sleeve 46 rotates, as shown in the attached Figure 2 and 3 As shown, since the linkage member 472 is a pair of bevel gears, which are respectively provided on the transmission shaft 471 and the screw rod 473, and the transmission shaft 471 does not rotate at this time, the rotation of the rotating sleeve 46 will inevitably cause the bevel gear located on the screw rod 473 to revolve, and since the pair of bevel gears are engaged, the bevel gear located on the screw rod 473 will also rotate on its own, synchronously driving the screw rod 473 to rotate on its own, and the screw rod 473 and the sliding member 474 are in threaded connection. Under the action of the thread force, the sliding member 474 will move outward, and the fitting member 48 will expand outward, and the fitting member 48 will fit on the inner wall of the glass body 6, so that the centering clamping of the glass body 6 is achieved;

[0058] See attached figure Figure 5-7 A movable ball 4751 is slidably inserted into the elastic member 475 , and a round hole 4752 adapted to the movable ball 4751 is opened on the first splicing block 451 .

[0059] A spring 4753 is provided in the elastic member 475 , and the spring 4753 applies an outward thrust to the movable ball 4751 .

[0060] As the fitting part 48 is completely fitted to the inner wall of the glass body 6, the screw rod 473 can no longer rotate, but the clamp assembly 4 continues to move forward, and the gear 461 is still rotating. Therefore, by providing a movable ball 4751 at the bottom of the elastic part 475, after the fitting part 48 is fully unfolded, the torsion exerted on the transmission shaft 471 continues to increase, so that the movable ball 4751 will retract against the elastic force of the spring 4753, and the movable ball 4751 will disengage from the circular hole 4752, so that the elastic part 475 can rotate compared to the first splicing block 451. Through the above structure, the glass body 6 can be automatically centered and clamped during transportation, and driven to rotate, thereby ensuring transportation stability, and the flamethrower 5 is provided on one side to achieve uniform heating of the glass body 6.

[0061] Furthermore, the bonding member 48 is made of a material with high thermal conductivity and high temperature resistance. Its thermal conductivity is high, and the bonding member 48 is completely bonded to the inner wall of the glass body 6 and extends along the axial direction of the glass body 6. In this way, during the heating process, the bonding member 48 can be used to conduct heat to the port of the glass body 6, which helps to form a temperature step on the glass body 6 and further reduce the risk of breakage.

[0062] Furthermore, during the movement in the second area, since the bonding member 48 continuously applies an expanding pressure to the glass body 6, once some cracks appear on the glass body 6, the glass body 6 will be shattered under the action of the expanding force of the bonding member 48. Intelligent sorting can automatically remove cracked defective products through the overload of the bonding member, reducing detection costs and reducing waste of glass base materials.

[0063] 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.
