Description

Technical Field

[0001] This invention relates to the field of glass production equipment technology, and in particular to a stemmed glass welding device. Background Technology

[0002] A stemmed glass is an elegant and beautiful glass vessel, typically used for drinking red wine or champagne. Generally, the manufacturing process involves separately manufacturing the body and stem, then welding them together at high temperatures to form the stemmed glass we commonly see in daily life. Welding of stemmed glasses is usually achieved using a glass welding machine. An existing application (application number 202422791772.3) describes a fully automatic stemmed glass welding machine. This application includes a frame and a welding mechanism mounted on the frame. The frame includes a base, a lower turntable, and an upper turntable arranged sequentially from bottom to top. The lower and upper turntables are rotatably connected to the base. The base is equipped with a mechanism for driving the lower turntable and... The upper turntable rotates synchronously and intermittently. The welding mechanism includes several lower support seats, several upper clamps, several torches, and a lower crossbar. Each lower support seat is rotatably mounted on the lower turntable at intervals along its circumference. Each upper clamp is rotatably mounted on the upper turntable at intervals along its circumference, and each lower support seat corresponds to one upper clamp. The lower crossbar is located at the bottom of the lower turntable and extends along its rotation trajectory. The top structure of the lower crossbar is higher in the middle and lower at both ends. Each torch is rotatably mounted on the side of the lower turntable at intervals along its circumference and is located above the lower crossbar. This device has the following disadvantages: During welding, the cup body and cup foot need to move, but the existing torch position is fixed and cannot move with the connection between the cup body and cup foot. This results in a short contact time between the connection between the cup body and cup foot and the flame, leading to poor welding results. In addition, pausing the turntable to increase the contact time between the flame and the connection would lengthen the processing time and reduce processing efficiency. Summary of the Invention

[0022] A cup body adsorption component 3.3 is connected to the upper end of the lower top rod 3.51. The cup body adsorption component 3.3 includes a sleeve 3.31, which is fixed to the upper end of the lower top rod 3.51 by bolts. The sleeve 3.31 is connected to the ventilation groove. The upper end of the sleeve 3.31 is connected to the air supply pipe 3.32. A placement plate 3.33 is connected to the upper side of the air supply pipe 3.32. An adsorption hole is provided on the placement plate 3.33, which is connected to the air supply pipe 3.32.

[0023] A fixed frame 9 is also provided on the upper side of the turntable 2. A vacuum adsorption mechanism 9.1, a lubricating oil circulation mechanism 10 and an upper bridge plate 11 are also provided on the fixed frame 9. The vacuum adsorption mechanism 9.1 is connected to the workstation assembly device 3. The lubricating oil circulation mechanism 10 inputs lubricating oil into the workstation assembly device 3. The upper bridge plate assembly 11 is configured to cooperate with the workstation assembly device 3.

[0024] like Figure 17As shown, the vacuum adsorption mechanism 9.1 includes a vacuum generator 9.2, which includes a sealed box body. The box body is fixed to the upper side of the fixing frame 9 by bolts. A vacuum pump is provided inside the box body, and an exhaust pipe is provided on the upper side of the box body. The exhaust pipe is connected to the exhaust port of the vacuum pump. A set of suction connectors is connected to the outside of the box body. The suction connectors are connected to a gas distribution mechanism through pipes. The gas distribution mechanism is connected to the corresponding fourth air holes 3574 through a set of air pipes 9.3. The gas distribution mechanism includes an annular box body 9.4, which is connected to the lower side of the fixing frame 9 and has an open lower side. The annular box body 9.4 is connected to the suction connectors through a set of pipes.

[0025] like Figure 18 As shown, a first gas distribution plate 9.5 is rotatably connected to the lower opening of the annular box 9.4. The first gas distribution plate 9.5 has an annular plate structure with annular grooves on both the inner and outer sides. An annular retaining plate is located in each annular groove, and each annular retaining plate is connected to an annular fixing plate 9.9. Both annular fixing plates 9.9 are connected to the opening of the annular box 9.4, allowing the first gas distribution plate 9.5 to rotate between the two annular fixing plates 9.9. A set of first air holes 9.7 are provided on the circumference of the first gas distribution plate 9.5, forming an annular air cavity between the first gas distribution plate 9.5 and the annular box 9.4. A second gas distribution plate 9.6 is connected to the lower side of the first gas distribution plate 9.5. The second gas distribution plate 9.6 is connected to... Connected to turntable 2, the turntable 2 drives the second gas distribution plate 9.6 to rotate. A set of L-shaped second air holes 9.8 are provided on the circumference of the second gas distribution plate 9.6. The second air holes 9.8 are corresponding to the first air holes 9.7.

The sealing block is located in the annular air cavity. The sealing block can block the corresponding first air holes 9.7 on the first gas distribution plate 9.33. That is, when the corresponding workstation assembly device 3 rotates to the material feeding device 8 below, the sealing block can block the corresponding first air holes 9.7, so that the corresponding cup body adsorption component 3.3 loses its suction, thereby enabling the material feeding device 8 to complete the feeding of the cup body.

[0026] The lubricating oil circulation mechanism 10 works in conjunction with the lubrication system inside the machine body 3.1. The lubrication system is an existing structure, including an oil inlet 3.8, lubrication pipelines, and an oil drain pipe 3.9.

[0027] like Figure 24As shown, the lubricating oil circulation mechanism 10 includes a main pipe 101, to which a set of oil delivery pipes 102 are connected. The oil delivery pipes 102 are hook-shaped, and the oil inlet 3.8 is configured to cooperate with the oil delivery pipes 102, that is, the lubricating oil output from the oil delivery pipes 102 can drip into the oil inlet 3.8 to lubricate the parts inside the machine body 3.1. The lubricating oil that enters the machine body 3.1 is finally discharged from the oil drain pipe 3.9. An annular oil box 104 is connected to the base 1 by a set of support rods. The annular oil box 104 is located below the oil outlet of the oil drain pipe 3.9. The discharged lubricating oil enters the annular oil box 104. An oil pump is connected to the lower side of the annular oil box 104 by a delivery pipe. The oil pump is connected to the main pipe 101 through the output pipe 103. The oil pump fills the input main pipe 101 with the lubricating oil in the annular oil box 104, thereby forming a circulation of lubricating oil.

[0028] An oil leak prevention component 312 is connected between every two adjacent machine bodies 3.1. The oil leak prevention component 312 is an arched plate with baffles connected to both sides of the arched plate. Two corresponding oil inlets 3.8 are set on the upper side of each end of the arched plate. When the machine body 3.1 rotates, the lubricating oil will drip onto the arched plate and flow along the arched plate to the oil inlets 3.8 on both sides. This can prevent the lubricating oil from falling between the two machine bodies 3.1 and prevent lubricating oil waste.

[0029] like Figure 25 and Figure 26 As shown, the upper bridge plate 11 includes two upper bridge plates, which are configured to cooperate with the upper transmission mechanism 3.4. The two upper bridge plates 11 are connected to the upper side of the fixed frame 9 through the bracket 111. The upper structure of the upper bridge plate 11 is a central protrusion with both sides inclined downward. When the upper transmission mechanism 3.4 passes the upper bridge plate 11, the upper transmission mechanism 3.4 controls the cup foot gripper 3.2 to open to clamp the cup foot. The two upper bridge plates can control the cup foot gripper 3.2 to clamp or release the cup foot in the corresponding position.

[0030] like Figure 19 As shown, a lower overpass plate assembly 17 is also connected to the base 1. The lower overpass plate assembly 17 is configured to cooperate with the traveling wheel 3.54, as shown. Figure 23As shown, the lower bridge plate assembly 17 includes a first bridge plate 171 and a second bridge plate 172. An input plate 173 is hinged to the input end of the first bridge plate 171. The input plate 173 is inclined downwards, and a first support plate is connected to the lower end of the input plate 173. The first support plate is connected to the base 1. A step plate assembly 175 is sequentially connected to the upper side of the first bridge plate 171. In this embodiment, the step plate assembly 175 includes two step plates, thus forming two upward steps. A first output plate 174 is hinged to the output end of the first bridge plate 171. The first output plate 174 is inclined downwards and is positioned... On the upper side of the first bridge plate 171, a second output plate 178 is hinged to the output end of the second bridge plate 172. A second support plate is connected to the lower end of the second output plate 178. The second support plate is connected to the base 1. The lower sides of the first bridge plate 171 and the second bridge plate 172 are supported and lifted by a lifting support mechanism 176. The lifting support mechanism 176 consists of two sets of worm gear lifts. The first bridge plate 171 and the second bridge plate 172 are moved up and down by the two sets of worm gear lifts. The worm gear lift is existing technology, so its structure, series connection method and driving method will not be described in detail.

[0031] When the walking wheel 3.54 travels on the first bridge plate 171 and the second bridge plate 172, the cup body suction component 3.6 can drive the cup body and the upper cup foot to move relative to each other, so that the distance between the cup body and the cup foot is first pulled closer. Then, the cup body is melted by the flame spraying device 6 below. After passing through two step plates 175, the connection between the cup body and the cup foot is squeezed together. When passing through the first output plate 174, the connection between the cup body and the cup foot is stretched. Finally, before passing through the second output plate 178, the cup foot gripper 3.4 has released the cup foot. At the same time as the cup foot is released, the cup body suction component 3.6 drives the cup body to move downwards, so that the cup body moves to the feeding device 8. At this time, the sealing block blocks the corresponding first air hole 9.7, so that the corresponding cup body suction component 3.3 loses its suction force, and the feeding device 8 can then complete the feeding of the cup body.

[0032] like Figure 19-21As shown, a self-rotating drive mechanism is connected to the base 1. The self-rotating drive mechanism includes a transmission belt mechanism and a drive device 14. The transmission belt mechanism includes a support frame 18, on which a set of guide support wheels 15 are connected. A transmission belt 13 is sleeved on the set of guide support wheels 15. The transmission belt 13 drives the transmission wheel 3.7. In this embodiment, the transmission belt 13 is a chain, and the transmission wheel 3.7 is a sprocket. The sprocket meshes with the chain, that is, when the workstation assembly device 3 rotates, it will drive the transmission wheel 3.7 to rotate. The transmission wheel 3.7 meshes with the transmission belt 13, which will drive the transmission wheel 3.7 to rotate. The transmission wheel 3.7 drives the main drive shaft 3.6 to rotate, and the main drive shaft 3.6 will drive the cup foot gripper 3.2 and the cup body adsorption component 3.3 to rotate.

[0033] The transmission belt mechanism also includes a tensioner assembly 16, which includes three tensioner mechanisms. Each tensioner mechanism includes a support column 161, a fixed plate 162 connected to the upper side of the support column 161, a through hole on the fixed plate 162, a threaded sleeve 163 connected to one side of the through hole, a screw 164 threadedly connected inside the threaded sleeve 163, the screw 164 rotatably connected to a movable plate 165 through the through hole, a guide rod 167 connected to one side of the movable plate 165, a corresponding guide hole on the fixed plate 162, a guide rod 167 inserted into the guide hole, and a tensioner 166 rotatably connected to the movable plate 165. The tension of the chain 13 is adjusted by the tensioner 166.

[0034] The driving device 14 drives the transmission belt 13 to rotate. The driving device 14 includes a placement frame 141, a set of bearing sleeves 142 connected to the placement frame 141, a rotating shaft inserted into the bearing sleeves 142, and a second sprocket 143 connected to the upper end of each rotating shaft. A chain meshes between the set of second sprockets 143. A first bevel gear is connected to the lower side of one of the rotating shafts. A third motor 144 is provided on the lower side of the placement frame 141. The third motor 144 is equipped with a reducer. A second bevel gear is connected to the output shaft of the reducer. The second bevel gear meshes perpendicularly with the first bevel gear. The third motor 144 drives one of the second sprockets 143 to rotate, thereby driving the chain to rotate. The rotation of the chain further accelerates the rotation speed of the cup foot gripper 3.2 and the cup body adsorption component 3.3.

[0035] On the outer side of turntable 2, along its rotation direction, are arranged a cup holder feeding device 4, a cup body feeding device 5, a flame-blowing device 6, an air-cooling device 7, and a feeding device 8.

[0036] The cup holder feeding device 4, the cup body feeding device 5, and the unloading device 8 are all existing robotic gripping structures. The cup holder feeding device 4 and the unloading device 8 have the same structure, both being support rods that clamp the cup feet. The cup body feeding device 5 is used to clamp the cup body.

[0037] In this embodiment, the number of flame-spraying devices 6 is two, such as... Figure 3 As shown, the flame-throwing device 6 includes a first support frame 6.1, a first reciprocating moving mechanism 6.2 connected to the first support frame 6.1, a flame-throwing mechanism 6.3 provided on the first reciprocating moving mechanism 6.2, and a gas supply mechanism 6.4 and a gas mixing mechanism 6.5 provided on the first support frame 6.1. The gas supply mechanism 6.4 is connected to the gas mixing mechanism 6.5 through a pipe.

[0038] The gas mixing mechanism 6.5 is connected to the flame-spraying mechanism 6.3 via a pipe. Natural gas and oxygen are delivered to the flame-spraying mechanism 6.3 through the gas supply mechanism 6.4 and the gas mixing mechanism 6.5 to weld the connection between the cup foot and the cup body. The first reciprocating moving mechanism 6.2 allows the flame-spraying mechanism 6.3 to move with the welding point, ensuring the welding effect. The pipes are not shown in the figure. All pipes are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods.

[0039] like Figure 4 As shown, the first reciprocating moving mechanism 6.2 includes a mounting plate 6.21 and a first mounting strip 6.22.

A mounting bracket 6 is fixedly connected to one side of the connecting plate 6.25. 26. A fourth motor 6.27 is fixedly connected to the mounting bracket 6.26. The output end of the fourth motor 6.27 is fixedly connected to a gear 6.29 that meshes with the rack 6.28 via a reducer. By starting the fourth motor 6.27, the gear 6.29 rotates. Because the gear 6.29 meshes with the rack 6.28, the first mounting strip 6.22, which is equipped with the rack 6.28, moves on the mounting plate 6.21 via the guide roller 6.24. This ensures that the flame-spraying mechanism 6.3 can follow the welding point and ensure the welding effect. After a set of cup body and cup foot is welded, the drive motor 6.27 is started again to rotate the gear 6.29 in the opposite direction, causing the first mounting strip 6.22 to drive the flame-spraying mechanism 6.3 to move to the initial position, waiting for the next round of cup foot and cup body.

[0040] like Figure 5As shown, the cross-section of the first mounting strip 6.22 is trapezoidal, and the bottom of the guide roller 6.24 is located above the protruding structure of the first mounting strip 6.22 and abuts against it; the guide roller 6.24 limits the first mounting strip 6.22 to prevent it from moving up and down.

[0041] like Figure 6 As shown, the gas delivery mechanism 6.4 includes two sets of first brackets 6.41 fixedly installed on the first support frame 6.1. A first gas delivery pipe 6.42 and a second gas delivery pipe 6.43 are detachably installed on the first brackets 6.41. Multiple sets of delivery pipes 6.44 are fixedly connected to the first gas delivery pipe 6.42 and the second gas delivery pipe 6.43. The delivery pipes 6.44 are connected to the gas mixing mechanism 6.5 through pipes. One end of the first gas delivery pipe 6.42 and the second gas delivery pipe 6.43 is provided with a connector, which is connected to the supply source of natural gas and oxygen respectively through the connector.

[0042] The first bracket 6.41 has a positioning hole, and a U-shaped rod is installed inside the positioning hole. The first air supply pipe 6.42 and the second air supply pipe 6.43 are located inside the two sets of U-shaped rods, respectively. The outer surfaces of both ends of the U-shaped rod have threaded grooves 6.317, and fixing nuts are threaded onto the threaded grooves 6.317. By tightening the fixing nuts, the U-shaped rod can be detached from the positioning rod, thus achieving a detachable effect. like Figure 7 and Figure 8 As shown, the gas mixing mechanism 6.5 includes two sets of second brackets 6.51 fixedly installed with the first support frame 6.1. A horizontal plate 6.52 is fixedly connected to the second bracket 6.51, and a mixing component 6.53 adapted to the flame-throwing mechanism 6.3 is fixedly connected to the horizontal plate 6.52. By setting up the mixing component 6.53 to mix natural gas and oxygen, the welding work of the flame-throwing mechanism 6.3 is facilitated.

[0043] The mixing assembly 6.53 includes a mounting base 6.531 connected to the first support frame 6.1. A connecting base 6.532 is detachably mounted on the mounting base 6.531. Limiting grooves 6.533 are formed on one side of both the connecting base 6.532 and the mounting base 6.531. An air supply pipe 6.534 is provided between the two sets of limiting grooves 6.533. One end of the air supply pipe 6.534 is fixedly connected to a mixing cylinder 6.535, and the other end of the air supply pipe 6.534 is connected to a flame-throwing mechanism 6.3 via a pipe. A second air pipe 6.536 is fixedly connected to the side of the mixing cylinder 6.535 away from the air supply pipe 6.534. A connecting pipe 6.537 is fixedly connected to one side of the mixing cylinder 6.535, and a first air pipe 6.538 is fixedly connected to the other side of the connecting pipe 6.537. Equipment is installed on the first air pipe 6.538 and the second air pipe 6.536. Valve 6.539, first gas pipe 6.538, and second gas pipe 6.536 are respectively connected to the delivery pipe 6.44 on the first gas delivery pipe 6.42 and the second gas delivery pipe 6.43. The limiting groove 6.533 has an arc-shaped structure. The mounting base 6.531 is provided with a threaded hole, and the connecting base 6.532 is provided with a through hole corresponding to the threaded hole. The inside of the through hole is provided with a threaded rod adapted to the threaded hole. Natural gas and oxygen are delivered to the first gas pipe 6.538 and the second gas pipe 6.536 respectively through the first gas delivery pipe 6.42 and the second gas delivery pipe 6.43. Then, the natural gas and oxygen enter the mixing cylinder 6.535. After mixing, they are delivered to the flame-spraying mechanism 6.3 to facilitate subsequent welding work. The valve 6.539 can adjust the closed state of the first gas pipe 6.538 and the second gas pipe 6.536.

[0044] like Figures 9-10As shown, the flame-spraying mechanism 6.3 includes multiple sets of first adjustment components 6.31 fixedly connected to the first reciprocating moving mechanism 6.2. Each first adjustment component 6.31 is equipped with a flame-spraying gun 6.32, which is connected to the mixing component 6.53 via a pipe. Each first adjustment component 6.31 includes a support rod 6.311 fixedly connected to the first reciprocating moving mechanism 6.2. A first fixing box 6.312 is sleeved on the outer surface of the support rod 6.311. A crossbar 6.313 extends through one side of the first fixing box 6.312. A fixing ring 6.314 and a second fixing box 6.315 are sleeved on the outer surface of the crossbar 6.313. Mounting hole 6.316 is provided on the 315. Flamethrower 6.32 is installed and connected inside mounting hole 6.316. Threaded groove 6.317 is provided on one side of the outer surface of crossbar 6.313. Threaded sleeve 6.318 is threadedly connected to the outer surface of crossbar 6.313 through threaded groove 6.317. One side of threaded sleeve 6.318 abuts against the second fixing box 6.315. The height of flame gun 6.32 can be adjusted by the first fixing box 6.312, the angle of flame gun 6.32 can be adjusted by rotating the second fixing box 6.315, and then fixed by screwing on threaded sleeve 6.318, thus achieving the effect of adjustable flame gun 6.32.

[0045] A handle is fixedly connected to one side of the threaded sleeve 6.318, making it easy for users to turn the threaded sleeve 6.318.

[0046] The flame-spraying mechanism 6.3 is aligned with the cup foot and cup body to be welded. Natural gas and oxygen are supplied to the first gas pipe 6.538 and the second gas pipe 6.536 respectively through the first gas pipe 6.42 and the second gas pipe 6.43. Then, the natural gas and oxygen enter the mixing cylinder 6.535, and after mixing, they are supplied to the flame-spraying gun 6.32 for welding at the connection between the cup foot and cup body. To ensure the welding effect, since the turntable supporting the cup body and cup foot is rotating, the first reciprocating movement mechanism 6.2 needs to be activated to rotate the flame-spraying mechanism 6.3 along with the turntable. After welding is completed, the first reciprocating movement mechanism 6.2 is activated again to return the flame-spraying mechanism 6.3 to the initial position to wait for welding the next set of cup feet and cup bodies. By setting up the first reciprocating movement mechanism 6.2, the flame-spraying mechanism 6.3 can move with the welding point, thus ensuring the welding effect without affecting work efficiency.

[0047] In this embodiment, the number of air-cooled devices 7 is two, such as... Figure 11As shown, the air-cooling device 7 includes a second support frame 7.1, on which a second reciprocating moving mechanism 7.2 is connected. A blower mechanism 7.3 is mounted on the second reciprocating moving mechanism 7.2. An air supply mechanism 7.4 is also mounted on the second support frame 7.1. The air supply mechanism 7.4 is connected to the blower mechanism 7.3 via a pipe. The air supply mechanism 7.4 delivers cold air to the blower mechanism 7.3 to cool the welded joint between the cup foot and the cup body. The second reciprocating moving mechanism 7.2 allows the blower mechanism 7.3 to move with the welded joint, ensuring effective cooling. The pipes are not shown in the figure. All pipes are standard components or parts known to those skilled in the art, and their structure and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods.

[0048] like Figure 12 As shown, the second reciprocating moving mechanism 7.2 includes a second mounting plate 7.21 and a second mounting strip 7.22. The second mounting plate 7.21 is fixedly connected to the top of the second support frame 7.1. Two sets of guide assemblies are fixedly connected to the top of the second mounting plate 7.21. Each set of guide assemblies includes a base plate 7.23 fixedly mounted on the top of the second mounting plate 7.21. A guide roller 7.24 is rotatably connected to the top of the base plate 7.23. Figure 13 As shown, the second mounting strip 7.22 is slidably mounted on the top of the second mounting plate 7.21 via guide roller 7.24. A rack 7.28 is fixedly connected to one side of the second mounting strip 7.22, and a connecting plate 7.25 is fixedly connected to the top of the second mounting strip 7.22. A blower mechanism 7.3 is fixedly connected to the top of the connecting plate 7.25, and a mounting bracket 7.26 is fixedly connected to one side of the connecting plate 7.25. A fifth motor 7.27 is fixedly connected to the mounting bracket 7.26, and the output end of the fifth motor 7.27 is fixedly connected to a gear 7.29 that meshes with the rack 7.28 via a reducer. Since the turntable supporting the cup body and cup foot is in a continuous rotation state, in order to ensure the cooling effect, when the fifth motor 7.27 starts working, its output end drives the gear 7.29 to rotate via the reducer. The gear 7.29 and the second mounting strip... 7.22 The racks 7.28 on one side mesh with each other, thereby driving the second mounting strip 7.22 to slide on the guide roller 7.24 on the top of the second mounting plate 7.21. The sliding of the second mounting strip 7.22 will drive the connecting plate 7.25 fixedly connected to it to move, thereby causing the blower mechanism 7.3 fixed on the top of the connecting plate 7.25 to move synchronously with the rotation direction and speed of the turntable, so as to ensure that each position of the welding joint can be fully and evenly cooled. After the cooling operation of a set of cup feet and cup body is completed, the second reciprocating moving mechanism 7.2 is restarted, the drive motor 7.27 reverses, and through the transmission action of gear 7.29 and rack 7.28, the second mounting strip 7.22 slides in the opposite direction, driving the blower mechanism 7.3 back to the initial position, waiting to cool the next set of cup feet and cup body that have just been welded.

[0049] like Figure 14 As shown, the air supply mechanism 7.4 includes two sets of brackets 7.43 fixedly installed on the second support frame 7.1. The brackets 7.43 are fixedly installed with air boxes 7.41. An air supply pipe 7.42 adapted to the blower mechanism 7.3 is fixedly connected to the air box 7.41. The air supply pipe 7.42 is connected to the blower mechanism 7.3 through a pipe. A valve 7.44 is provided on the air supply pipe 7.42. The air box 7.41 is connected to an external air conditioning unit to ensure a stable supply of cold air. The cold air generated by the external air conditioning unit is delivered to the blower mechanism 7.3 through the air supply pipe 7.42. The blower mechanism 7.3 concentrates the cold air and blows it onto the welding parts of the cup foot and the cup body to achieve rapid cooling of the area.

[0050] like Figure 15 As shown, the blower mechanism 7.3 includes multiple sets of second adjustment components 7.31 fixedly connected to the second reciprocating movement mechanism 7.2. The second adjustment components 7.31 are provided with air cooling heads 7.32, which are connected to the air supply mechanism 7.4 through pipes. The air supply mechanism 7.4 delivers cold air to the air cooling heads 7.32, and then sprays it out from the air cooling heads 7.32 to cool the welded joint between the cup body and the cup foot.

[0051] like Figure 16 As shown, the second adjustment assembly 7.31 includes a support rod 7.311 fixedly connected to the second reciprocating moving mechanism 7.2. A first fixing box 7.312 is sleeved on the outer surface of the support rod 7.311. A crossbar 7.313 is provided through one side of the first fixing box 7.312. A fixing ring 7.314 and a second fixing box 7.315 are sleeved on the outer surface of the crossbar 7.313. A mounting hole 7.316 is provided on the second fixing box 7.315. A connecting rod 7.319 is provided inside the mounting hole 7.316. The air cooling head 7.32 is fixedly connected to the connecting rod 7.319. On one side of 319, a threaded groove 7.317 is provided on the outer surface of the crossbar 7.313. A threaded sleeve 7.318 is threadedly connected to the outer surface of the crossbar 7.313 through the threaded groove 7.317. One side of the threaded sleeve 7.318 abuts against the second fixing box 7.315. The height of the air cooling head 7.32 can be adjusted by moving the first fixing box 7.312 up and down, the air blowing angle of the air cooling head 7.32 can be adjusted by rotating the connecting rod 7.319, and then the threaded sleeve 7.318 can be screwed to complete the fixation, thereby achieving the effect of adjustable air cooling head 7.32.

[0052] When using this device, first, precisely align the air-cooling head 7.32 of the blower mechanism 7.3 with the welded connection between the cup foot and the cup body. Connect the air box 7.41 in the air supply mechanism 7.4 to the external air-generating equipment to ensure a stable supply of cold air. The cold air generated by the external air-generating equipment will be delivered to the air-cooling head 7.32 through the air supply pipe 7.42. The air-cooling head 7.32 will concentrate the cold air and blow it onto the welded area between the cup foot and the cup body, achieving rapid cooling of this area. Since the turntable supporting the cup body and cup foot is in a continuous rotation state, in order to ensure the cooling effect, the second reciprocating moving mechanism 7.2 needs to be activated. The drive motor 7.27 in the second reciprocating moving mechanism 7.2 starts working, and its output end drives the gear 7.29 to rotate through the reducer. The gear 7.29 meshes with the rack 7.28 on one side of the second mounting strip 7.22, thereby driving the second mounting strip 7.22 to the top of the second mounting plate 7.21. The guide roller 7.24 slides, and the sliding of the second mounting strip 7.22 will drive the connecting plate 7.25 fixedly connected to it to move. In turn, the blower mechanism 7.3 fixed on the top of the connecting plate 7.25 moves synchronously with the rotation direction and speed of the turntable, always keeping the air cooling head 7.32 precisely aligned with the welding point. This ensures that every position at the welding point receives sufficient and uniform cooling. After the cooling operation of a set of cup feet and cup body is completed, the second reciprocating moving mechanism 7.2 is started again, and the drive motor 7.27 reverses. Through the transmission action of gears 7.29 and racks 7.28, the second mounting strip 7.22 slides in the reverse direction, driving the blower mechanism 7.3 back to the initial position, waiting to cool the next set of cup feet and cup body that have just been welded. Through this workflow, this device can significantly improve the cooling effect after welding of stemmed cups without affecting the overall production line processing efficiency, thus ensuring product quality.

[0053] Working principle: First, the drive device 1.1 drives the turntable 2 to rotate. The turntable 2 drives the corresponding workstation assembly device 3 to the upper center of the first upper bridge plate 11, causing the cup foot gripper 3.2 to open. Then, the cup foot is fed by the cup foot feeding device 4, so that the cup foot gripper 3.2 can hold the cup foot. The turntable 2 then rotates, and the cup body is fed by the cup body feeding device 5, so that the cup body is placed on the placement tray 3.33. The vacuum adsorption mechanism 9.3 adsorbs the cup body on the placement tray 3.33. Next, the traveling wheel 3.54 travels on the lower bridge plate assembly 17, so that the cup body adsorption component 3.6 can drive the cup body and the upper cup foot to move relative to each other, so that the distance between the cup body and the cup foot is first pulled closer. Then, the flame device 6 below melts the flame. After passing through two stepped plates 175, the connection between the cup body and the cup foot is joined together. When passing through the first output plate 174, the connection between the cup body and the cup foot is stretched to control the height of the stemmed cup. Then, the welded joint is rapidly cooled by the air cooling device 7. Finally, before passing through the second output plate 178, it passes through the second upper bridge plate 11, where the cup foot gripper 3.2 releases the cup foot, allowing the welded cup body to fall onto the placement tray 3.33. After passing through the second output plate 178, the welded cup body moves to the unloading device 8. At this time, the corresponding first air hole 9.7 moves to the sealing plate, which seals the corresponding first air hole 9.7, causing the corresponding cup body adsorption component 3.3 to lose its adsorption force. The unloading device 8 can then unload the welded cup body.
