Description

Technical Field

[0001] This invention relates to the field of glass machinery technology, specifically to the cantilever and bottle clamping mechanism and production process for a five-line bottle making machine. Background Technology

[0002] Traditional row-type bottle making machines are commonly referred to in the industry as "four-row machines" because the glass bottle manufacturing process mainly includes four stations: the initial mold station, the forming station, the resting plate station, and the conveyor belt station. The initial mold and forming sides are connected by a flipping mechanism, the forming side and the resting plate by a bottle clamping mechanism, and the resting plate and the conveyor belt by a bottle-pushing mechanism. Glass bottles enter the bottle making machine as droplets and are formed. The production process can be simply described as follows: the glass droplets first enter the initial mold at the initial mold station, where they undergo steps such as air blowing, back blowing, or stamping to form a preliminary preform. The flipping mechanism flips the mouth mold and the preliminary preform into the forming mold at the forming side station. After a forward blowing process in the forming mold, a formed bottle is formed. Then, the forming mold opens, and the bottle clamping mechanism transfers the formed bottle from the forming mold to the resting plate for cooling. Finally, the bottle-pushing mechanism transfers the glass bottles from the resting plate surface onto the conveyor belt for output.

[0003] The above-described production process is for one column of a row-type bottle-making machine. However, with the continuous improvement of people's aesthetic standards, some special-shaped glass bottles are gradually gaining popularity, such as thick-bottomed glass bottles and high-brightness glass bottles. These high-end glass bottles are generally produced in small batches with multiple varieties. Therefore, when processing high-end glass bottles, different types of glass bottles may be produced simultaneously in different columns of the row-type bottle-making machine. However, traditional row-type bottle-making machines ("four-row machines") cannot meet these production demands. The reason is:

[0004] (1) Factors related to the bottle clamping mechanism. The function of the bottle clamping mechanism is to transfer the glass bottle in the molding mold to the stationary plate. During this transfer process, the bottle body needs to remain vertical to prevent damage from impact between the bottle mouth and the bottle body. The cantilever bottle clamping mechanism is a common type, such as the technical solution described in the Chinese utility model patent with application number 202221301086.8, application date May 27, 2022, and patent name "A Quickly Adjustable Bottle Clamping Mechanism".

[0005] In the cantilever bottle clamping mechanism, the power shaft of the power mechanism is connected to the housing of the cantilever, and the input shaft of the cantilever passes through the power shaft of the power mechanism. The bottle clamping bracket is installed on the output shaft of the cantilever, and a bottle clamping jaw for gripping glass bottles is installed at the bottom of the bottle clamping bracket. When the power mechanism outputs power to the housing of the cantilever, it drives the housing of the cantilever to perform a combined motion of lifting, lowering, and translating in the vertical direction. During this process, the input shaft of the cantilever remains stationary, while the output shaft of the cantilever rotates on its own axis and revolves around the input shaft. The bottle clamping bracket remains in a vertical state. The cantilever further drives the bottle clamping bracket to move back and forth between the forming side station and the stopping plate station, realizing the clamping of bottles from the forming side station and the release of bottles from the stopping plate station.

[0006] The fundamental reason why traditional cantilever bottle clamping mechanisms cannot produce different types of glass bottles in different rows of a row-type bottle making machine is that the components of the traditional cantilever bottle clamping mechanism cannot be adjusted. Specifically: 1) As is generally known in the field, in the initial mold side station and the forming side station of a "four-row machine," the distance between the initial mold and the forming mold is fixed and cannot be adjusted due to the position of the mold and the flipping mechanism. Furthermore, in the stop plate station and the conveyor belt station, the surface height of the conveyor belt must remain at the same horizontal plane throughout the entire conveying process. This means that the stop plate and the bottle-shifting mechanism must be at the same horizontal plane as the conveyor belt. In other words, the spacing of the processes preceding the bottle clamping mechanism is a fixed value, and the height of the processes following the bottle clamping mechanism is also a fixed value. Moreover, the spacing between the forming side station and the stop plate station in different rows of a row-type bottle making machine cannot be independently adjusted.

[0007] Therefore, when different types of glass bottles need to be produced in different columns of a row-type bottle making machine, the bottle clamping mechanism in different columns of the row-type bottle making machine needs to have different motion trajectories. Furthermore, since the bottle clamping mechanism is a compound motion of lifting and translation during operation, and the components of the traditional cantilever bottle clamping mechanism cannot be adjusted, it is difficult to meet the processing requirements of high-end glass bottles.

[0008] (2) Polishing Mechanism Factors. When producing high-brightness glass bottles, polishing is required. Since the glass bottles are exposed to high temperatures during production, the most suitable polishing method is hot polishing (such as fire polishing using a spray gun). However, traditional four-row machines do not have a polishing process within their internal workstations. Existing polishing technology places the fire polishing mechanism at the end of the bottle-making process on the conveyor belt, as described in Chinese Utility Model Patent Application No. 202423009555.0, filed on December 6, 2024, entitled "A Fire Polishing Device for Glass Products." The drawback of this fire polishing method is that by the time the glass bottle reaches the conveyor belt, its temperature has already dropped significantly, making it difficult to achieve the desired polishing effect and resulting in a large waste of fuel.

[0009] (3) Cooling Factors. For traditional glass bottles, the thickness of the body and the bottom can be considered approximately the same. However, for thick-bottomed glass bottles, the thickness of the bottom is significantly greater than the thickness of the body. Therefore, the cooling methods used in traditional "four-row machines" are insufficient to cool thick-bottomed glass bottles. Furthermore, because the bottom of the glass bottle is thicker, it accumulates a lot of heat during the internal processing. If a large temperature difference is forcibly applied to cool the bottle after it is output from the forming side, the glass bottle is prone to cracking due to the large temperature difference, seriously affecting the quality of the product.

[0010] Therefore, designing a technical solution that can upgrade the traditional four-row machine in the simplest way possible to produce high-end glass bottles such as thick-bottomed glass bottles and high-brightness glass bottles, while also meeting the production mode of small batches and multiple varieties of high-end glass bottles, has become an urgent problem to be solved in this field. Summary of the Invention

[0011] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a cantilever and clamp bottle clamping mechanism and production process for a five-row bottle making machine. By setting an adjustable clamping device, the height difference between glass bottles of different shapes can be eliminated. Therefore, it is possible to produce glass bottles of different shapes in different columns of the five-row bottle making machine at the same time. By simply upgrading the traditional row-type bottle making machine, it is possible to produce high-grade glass bottles through the traditional four-row machine, while meeting the production mode of small batch and multiple varieties of high-grade glass bottles.

[0012] The technical solution adopted by the present invention to solve its technical problem is: the cantilever and bottle clamping mechanism of the five-element bottle making machine includes a cantilever assembly and a bottle clamping assembly. The bottle clamping assembly includes a bottle clamping bracket and a gripper device disposed on both sides of the bottle clamping bracket. The cantilever assembly is connected to the bottle clamping bracket in the bottle clamping assembly. The feature is that: a mounting seat is provided at the end of the bottle clamping bracket. The mounting seat is slidably connected to the bottle clamping bracket. The gripper device is mounted on the side of the mounting seat in a liftable manner.

[0013] Preferably, the mounting base is located at both ends of the clamp bottle bracket, and the gripper device is mounted on the side of the mounting base away from the connection between the cantilever assembly and the clamp bottle assembly.

[0014] Preferably, an adjustment mechanism for achieving unidirectional translation between the two mounting seats is installed at the bottom of the clamp bottle bracket; the adjustment mechanism includes an adjustment rod, the two ends of which are threadedly connected to the mounting seats at both ends.

[0015] Preferably, the thread pitches at both ends of the adjusting rod are different.

[0016] Preferably, a liftable internal cooling pipe is provided at the bottom of the clamp bottle bracket, and a delivery channel for supplying cooling air to the internal cooling pipe is formed by docking within the connected cantilever assembly and clamp bottle assembly.

[0017] Preferably, the cantilever assembly includes a cantilever housing, and the cantilever input shaft and the cantilever output shaft are rotatably and vertically disposed on two opposite end faces of the cantilever housing. The cantilever input shaft and the cantilever output shaft are connected inside the cantilever housing by a transmission mechanism, and the clamp bottle bracket is fitted outside the cantilever output shaft.

[0018] The production process of the Five Elements Bottle Making Machine, which utilizes a cantilever and bottle clamping mechanism, is characterized by the following steps:

[0019] Step a: The glass material droplet forms a preliminary preform in the first station, and the preliminary preform is transferred to the second station by the flipping mechanism, where it forms a molded bottle.

[0020] Step b: The cantilever assembly rotates forward and, through the gripper devices on both sides of the bottle clamping bracket, transfers the molded bottle obtained in the second station to the third station, and at the same time transfers the original molded bottle in the third station to the fourth station.

[0021] Step c: The cantilever assembly performs the first reverse rotation and stops above the formed bottle in the third station. The formed bottle is then polished, and internal and external cooling processes are performed in the third station.

[0022] In step d, the cantilever assembly performs a second reverse rotation, causing the gripper devices on both sides of the bottle clamp support to return to the upper part of the second and third workstations and face downwards towards the formed bottles in their respective workstations.

[0023] Preferably, before performing step a, an adjustment step is also performed, in which the gripper devices located at the upper part of the second and third workstations in step d are adjusted laterally with different spacings; and the relative position of the gripper devices and the mounting base in the vertical direction is adjusted vertically.

[0024] Preferably, the lateral adjustment distance of the gripper device located at the upper part of the second station is: R{1-cos[arcsin((hc / 6) / R)]};

[0025] The lateral adjustment distance of the gripper device located at the upper part of the third station is: 2R{1-cos[arcsin((hc / 6) / R)]};

[0026] The vertical adjustment distance between the gripper device and the mounting base in the vertical direction is: hc / 3;

[0027] Where R is the center distance between the axes of the cantilever input shaft and the cantilever output shaft in the cantilever assembly, and hc is the height difference between the tallest and shortest formed bottles in the five-line bottle making machine.

[0028] Compared with the prior art, the beneficial effects of this invention are:

[0029] In the cantilever and clamp bottle fixture mechanism and production process of this five-row bottle making machine, the height difference between different types of glass bottles can be eliminated by setting an adjustable gripper device. Therefore, it is possible to produce different types of glass bottles in different columns of the five-row bottle making machine at the same time. By simply modifying the traditional row-and-column bottle making machine, it can meet the characteristics of small-batch, multi-variety production of high-end glass bottles.

[0030] In the five-element bottle-making machine, the third station is used to polish the glass bottles, which is more conducive to achieving the production requirements of high-brightness glass bottles.

[0031] In the third station, the glass bottles can be polished while also being cooled internally and externally. In particular, the bottom of the glass bottle can be cooled from both the top and bottom, achieving gradual cooling of the glass bottle throughout the bottle-making process. This avoids the possibility of the glass bottle exploding when forced to cool down by a large temperature difference, and is especially suitable for the production of thick-bottomed glass bottles.

[0052] Figures 1-19 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figures 1-19 The present invention will be further described below.

[0053] Example 1:

[0054] like Figures 1-2 As shown, the five-line bottle-making machine includes a first station 1, a second station 2, a third station 5, a fourth station 7, and a fifth station 9 arranged sequentially along the glass bottle 26 processing flow. The first station 1, the second station 2, the fourth station 7, and the fifth station 9 are respectively equivalent to the initial mold side station, the forming side station, the resting plate station, and the conveyor belt station in the traditional "four-line machine". The first station 1 and the second station 2 are connected by a flipping mechanism 3, which clamps and flips the die and the formed preform in the first station 1 (initial mold side station) into the forming mold in the second station 2 (forming side station). The support at the fourth station 7 and the fifth station 9 are connected by the bottle-transfer mechanism 8. The glass bottle 26 formed in the molding mold at the second station 2 is transferred to the surface of the rest plate 10 at the fourth station 7 for cooling. Finally, the bottle-transfer mechanism 8 transfers the glass bottle 26 on the surface of the rest plate 10 to the conveyor belt 11 at the fifth station 9 for output, and then performs subsequent cooling, steam coating, and bottle rejection processes.

[0055] In this Five Elements Bottle Making Machine (hereinafter referred to as "Five Elements Machine"), the specific implementation methods, working principles and working processes of the first station 1, the second station 2, the fourth station 7 and the fifth station 9 are the same as those of the prior art, and will not be repeated here.

[0056] Unlike the traditional "four-line machine," this five-line machine adds a third station 5, namely the fire polishing station, between the forming side station and the resting plate station. A fire polishing mechanism 6 is installed in the fire polishing station. The glass bottles 26 output from the forming side are first transferred to the fire polishing station, where they undergo polishing by the fire polishing mechanism 6. Then, the glass bottles 26 are transferred again from the third station 5 to the fourth station 7. In this five-line machine, placing the fire polishing station between the forming side station and the resting plate station maximizes the utilization of the residual heat from the glass bottles 26 as they exit the forming mold at the forming side station, reducing the fuel consumption of the fire polishing mechanism 6 during the hot polishing process of the glass bottles 26 at the station.

[0057] Combination Figure 3 The fire polishing mechanism 6 includes a polishing bracket 16, a nozzle bracket vertically arranged on one side of the polishing bracket 16, and a polishing nozzle 15 mounted on the top of the nozzle bracket. Gas and oxygen are respectively introduced into the polishing nozzle 15 through different pipes. A polishing drive motor 18 is provided on one side of the polishing bracket 16, a polishing drive gear 12 is fixed to the motor shaft of the polishing drive motor 18, a polishing driven gear 13 is meshed on one side of the polishing drive gear 12, and a polishing base mold 14 is coaxially fixed at the center of the polishing driven gear 13.

[0058] After the glass bottle 26 output from the second station 2 is transferred to the surface of the polishing base mold 14 by the cantilever clamping bottle mechanism 4, the polishing drive motor 18 drives the polishing base mold 14 to rotate through the polishing drive gear 12 and the polishing driven gear 13. The glass bottle 26 on the surface of the polishing base mold 14 rotates accordingly. During the rotation, flames are sprayed out from the polishing nozzle 15 on the side to achieve thermal polishing of the glass bottle 26.

[0059] An external cooling pipe 17 is provided on the top of the polishing mold 14. One end of the external cooling pipe 17 is connected to external cooling gas. The top of the external cooling pipe 17 extends upward to the center of the polishing mold 14 and communicates with the cooling port at the center of the polishing mold 14.

[0060] In a traditional four-line machine, the forming side station and the stopping plate station are connected by a bottle clamping mechanism. However, in this five-line machine, a cantilever bottle clamping mechanism 4 is also provided between the second station 2 and the third station 5. The cantilever bottle clamping mechanism 4 is different from the bottle clamping mechanism in the traditional four-line machine in that: the cantilever bottle clamping mechanism 4 of this application realizes the connection between the front and rear three stations at the same time: that is, the glass bottle 26 at the second station 2 is transferred to the third station 5, and at the same time the glass bottle 26 at the third station 5 is transferred to the fourth station 7.

[0061] like Figures 4-5As shown, the cantilever bottle clamping mechanism 4 includes a cantilever assembly 20 and a bottle clamping assembly. The bottle clamping assembly includes a bottle clamping bracket 21, which is connected to the cantilever assembly 20. A gripper device for grasping and placing glass bottles 26 is installed on the lower part of the bottle clamping bracket 21. Similar to the prior art, the cantilever assembly 20 is connected to the output shaft of a power mechanism (not shown in the figure). The rotation of the power mechanism drives the cantilever housing 38 (see figure 38). Figure 11 The cantilever housing 38 performs a combined lifting and translation motion. While the cantilever housing 38 performs the combined motion, the bottle clamp support 21 and the gripper device are always in a vertical state and move back and forth between the front and rear workstations with the cantilever assembly 20 to realize the transfer of glass bottles 26.

[0062] Combination Figures 6-7 Guide rods 24 are horizontally extended from both ends of the bottle clamp bracket 21. A first mounting seat 33 and a second mounting seat 25 are respectively provided on both sides of the base plate. The guide rods 24 on both sides pass through the first mounting seat 33 and the second mounting seat 25 respectively. Therefore, the first mounting seat 33 and the second mounting seat 25 can slide along the guide rods 24 on the corresponding sides respectively.

[0063] A gripper device is provided at the first mounting base 33 and the second mounting base 25 respectively. The gripper device at the first mounting base 33 is directly installed at the bottom of the first mounting base 33, and the gripper device at the second mounting base 25 is movably installed on the side of the second mounting base 25. Figures 8-9 As shown, an adjustment groove 35 is provided in the middle of the side plate of the second mounting base 25. The gripper device of the second mounting base 25 is inserted into the adjustment groove 35 through the dovetail groove structure on its side. A positioning screw 34 is installed in the adjustment groove 35. The positioning screw 34 passes through the adjustment groove 35 and is screwed into the gripper device. After the height position of the gripper device is adjusted, it is locked and positioned by the positioning screw 34.

[0064] When the height of the clamping assembly needs to be adjusted, the clamping assembly at the bottom of the first mounting base 33 is adjusted by the cantilever assembly 20, and then the height of the gripper device at the second mounting base 25 is adjusted separately. This allows for the simultaneous transfer of glass bottles 26 at both workstations without requiring the gripper devices at the first mounting base 33 and the second mounting base 25 to have independent lifting and lowering adjustment functions.

[0065] Similar to existing technologies, the gripper device includes a bottle-clamping cylinder 27, a bottle-clamping connecting rod 28, and grippers. The piston rod of the bottle-clamping cylinder 27 is connected to the upper part of the bottle-clamping connecting rod 28, and the grippers are installed at the lower part of the bottle-clamping connecting rod 28. When the piston rod of the bottle-clamping cylinder 27 rises and falls, it drives the grippers at the bottom to open and close through the bottle-clamping connecting rod 28, thereby gripping and placing the glass bottle 26. The specific structure of the bottle-clamping connecting rod 28 also adopts a structure known in the art, such as the "bottle clamping fixture" described in Chinese invention patent application number 202310689996.0, application date June 12, 2023, entitled "A Servo Bottle Clamping Mechanism for the Fourth Station of a Rotary Bottle Making Machine," which will not be described in detail here. The air inlet pipes of the two bottle-clamping cylinders 27 are respectively connected to an external air source. Through the external air source (in conjunction with a solenoid valve), air is supplied to the bottle-clamping cylinders 27, allowing for independent control of the two bottle-clamping cylinders 27.

[0066] An adjusting rod 23 is also provided below the base plate of the bottle clamp support 21. An adjusting column 22 is coaxially fixed in the middle of the adjusting rod 23. The adjusting column 22 preferably adopts an external hexagonal shaft that is coaxially fixed with the adjusting rod 23 so that the adjusting rod 23 can be rotated through the adjusting column 22. The top of the adjusting column 22 is embedded in the bottom surface of the base plate of the bottle clamp support 21 to limit the position of the adjusting column 22 and the adjusting rod 23.

[0067] The adjusting rod 23 is located between the two guide rods 24. Both ends of the adjusting rod 23 pass through the first mounting base 33 and the second mounting base 25, respectively. Each end of the adjusting rod 23 has two external threads in the same direction, and threaded sleeves 32 are installed in the first mounting base 33. One end of the adjusting rod 23 is threadedly connected to the first mounting base 33 via the threaded sleeve 32, and the other end is directly threadedly connected to the second mounting base 25. Therefore, when the adjusting rod 23 is rotated by the adjusting pin 22, the first mounting base 33 and the second mounting base 25 translate in the same direction under the action of the two guide rods 24.

[0068] like Figures 11-12 As shown, the cantilever assembly 20 includes a cantilever housing 38. A cantilever output wheel 42 and a cantilever input wheel 45 are arranged side-by-side within the cantilever housing 38. A cantilever tension wheel 47 is also provided on the side between the cantilever output wheel 42 and the cantilever input wheel 45. Both the cantilever output wheel 42 and the cantilever input wheel 45 are sprockets. A cantilever chain 46 is fitted around the cantilever output wheel 42, the cantilever input wheel 45, and the cantilever tension wheel 47, and simultaneously meshes with them.

[0069] A cantilever input shaft 39 is coaxially fixed at the cantilever input wheel 45, and a cantilever output shaft 44 is coaxially fixed at the cantilever output wheel 42. The cantilever output wheel 42 and the cantilever output shaft 44 extend from the front and rear end faces of the cantilever housing 38, respectively. Figure 13A connecting boss 48 is provided at the end of the cantilever housing 38 near the cantilever input shaft 39. The connecting boss 48 connects the cantilever housing 38 to the power shaft of the power mechanism so that the power mechanism can drive the cantilever housing 38 to rotate. At this time, the cantilever input shaft 39 passes through the power shaft of the power mechanism and is locked after passing through the power shaft of the power mechanism to prevent the cantilever input shaft 39 from rotating when the cantilever housing 38 rotates.

[0070] like Figure 14 As shown, a cantilever input channel 40 is axially formed at the center of the cantilever input shaft 39, a cantilever housing channel 41 is provided inside the cantilever housing 38, and a cantilever output channel 43 is axially formed at the center of the cantilever output shaft 44. The cantilever input channel 40, cantilever housing channel 41, and cantilever output channel 43 are connected end to end to form a cantilever channel.

[0071] Further integration Figure 10 as well as Figure 15 The top of the clamp bottle bracket 21 is provided with a mounting hole, and the connecting sleeve 19 is inserted into the mounting hole at the top of the clamp bottle bracket 21. The cantilever output shaft 44 is then inserted into the connecting sleeve 19 and rotatably connected to the connecting sleeve 19, thereby realizing the connection between the cantilever assembly 20 and the clamp bottle bracket 21.

[0072] A through hole communicating with the cantilever output channel 43 is radially opened at the end of the cantilever output shaft 44. A channel is opened inside the connecting sleeve 19. After the cantilever output shaft 44 and the connecting sleeve 19 are fitted together, the cantilever output channel 43 communicates with the channel inside the connecting sleeve 19. A support channel 36 is opened inside the clamp bottle support 21. The cantilever output channel 43 is further communicated with the support channel 36 through the channel inside the connecting sleeve 19. An internal cooling air hole 37 is provided on the bottom surface of the base plate of the clamp bottle support 21. The internal cooling air hole 37 is the air outlet port of the support channel 36. A cylindrical air pipe seat 29 is installed on the bottom surface of the base plate of the clamp bottle support 21. The upper end of the air pipe seat 29 is connected to the internal cooling air hole 37. The internal cooling air pipe 30 is inserted from the lower end of the air pipe seat 29. The internal cooling air pipe 30 is installed inside the air pipe seat 29 in a height-adjustable manner. An internal cooling air head 31 is installed at the bottom of the internal cooling air pipe 30.

[0073] An opening communicating with the cantilever input channel 40 is radially provided at the outer end of the cantilever input shaft 39. After the cantilever input shaft 39 passes through the power shaft of the power mechanism, it is connected to the external cooling air source. At this time, the external cooling air source passes through the cantilever input channel 40, the cantilever housing channel 41, the cantilever output channel 43, the channel in the connecting sleeve 19, and the bracket channel 36 in sequence, and enters the air pipe seat 29. It is then blown out by the internal cooling air head 31 at the end of the internal cooling air pipe 30 inside the air pipe seat 29.

[0074] The specific working process and working principle are as follows:

[0075] The production process achieved by the above-mentioned five-element bottle-making machine includes the following steps:

[0076] Step 1: Glass material is dripped into the first station 1 to form a preliminary bottle preform.

[0077] Step 2: The flipping mechanism 3 transfers the prototype blank to the molding mold in the second station 2, and forms a molded bottle in the molding mold.

[0078] Step 3: The cantilever clamp mechanism 4 grips the glass bottle 26.

[0079] The molding die in the second station 2 is opened, and the cantilever assembly 20 rotates to the initial position. During the process of the cantilever assembly 20 moving to the initial position, or before the cantilever assembly 20 moves to the initial position, gas is introduced into the bottle clamping cylinders 27 of the two side gripper devices, so that the piston rods of the two side bottle clamping cylinders 27 are output. The piston rods of the bottle clamping cylinders 27 open the grippers at the bottom through the corresponding bottle clamping connecting rods 28.

[0080] After the cantilever assembly 20 rotates to its initial position, the gripper devices on both sides are positioned directly above the bottle openings of the glass bottles 26 in the second and third workstations 2 and 5, respectively, with the two sets of grippers located outside the corresponding bottle openings of the glass bottles 26. An external air source actuates the bottle-clamping cylinder 27, resetting the piston rod. The grippers on both sides then grip the glass bottles 26 in the second and third workstations 2 and 5, respectively. Figure 16 The state shown.

[0081] Step 4, forward clamping of the cantilever clamping mechanism 4;

[0082] The cantilever assembly 20 rotates 180 degrees under the drive of the power mechanism. At this time, the glass bottles 26 originally in the second station 2 and the third station 5 are transferred to the third station 5 and the fourth station 7, respectively. Figure 17 The state shown.

[0083] Then the bottle clamp cylinders 27 on both sides are reset, and the glass bottles 26 that have been transferred to the third station 5 and the fourth station 7 are released by the gripper devices on both sides respectively.

[0084] Step 5, polishing of glass bottle 26 in the third station 5.

[0085] In the third station 5, the fire polishing mechanism 6 is working. After the polishing nozzle 15 is ignited, it performs hot polishing on the surface of the glass bottle 26. At the same time, the polishing drive motor 18 is working, which drives the glass bottle 26 to rotate, completing the circumferential hot polishing of the bottle body.

[0086] Step 6, cooling in the third station 5.

[0087] The cantilever assembly 20 rotates in the opposite direction under the drive of the power mechanism, stopping when the internal cooling air pipe 30 rotates with the cantilever to directly above the glass bottle 26 in the third station 5. At this time, the external cooling air source sequentially passes through the cantilever input channel 40, the cantilever housing channel 41, the cantilever output channel 43, the channel in the connecting sleeve 19, and the bracket channel 36 to enter the air pipe seat 29, and is blown out by the internal cooling air head 31 at the end of the internal cooling air pipe 30 inside the air pipe seat 29, and blown into the interior of the glass bottle 26 to achieve internal cooling of bottle A. Figure 18 The state shown.

[0088] Meanwhile, the cooling gas supplied by the external cooling pipe 17 passes through the polished bottom mold 14 to externally cool the bottom of the glass bottle 26.

[0089] As is known to those skilled in the art, the step of externally cooling the bottom of the glass bottle 26 through the external cooling pipe 17 can be performed simultaneously with the polishing of the glass bottle 26 by the fire polishing mechanism 6, or when the glass bottle 26 in the second station 2 is transferred to the third station 5.

[0090] Step 7: The cantilever clamp mechanism 4 returns to its initial position;

[0091] After the preset cooling time is reached, the cantilever assembly 20 completes the entire reverse rotation under the drive of the power mechanism, that is, the gripper devices on both sides return to the second station 2 and the third station 5 respectively, and so on.

[0092] As is known to those skilled in the art, the cantilever assembly 20 can be powered by a servo motor. Therefore, the reciprocating rotation of the cantilever assembly 20 and the method of achieving the hovering action at the top of the second workstation 2 are common knowledge and conventional methods known to those skilled in the art.

[0093] Example 2:

[0094] The difference between this embodiment and Embodiment 1 is that: in a certain column of the five-element bottle-making machine, a glass bottle 26 with a different shape than that in Embodiment 1 is produced, such as... Figure 19 The large-mouthed, short bottle is shown. Since the forming mold at the second station 2 and the stopping plate 10 at the fourth station 7 cannot be adjusted in height, when replacing the glass bottle 26 with another type, in addition to replacing the grippers of the same size, the height difference caused by replacing the glass bottle 26 is eliminated by adjusting the cantilever clamp mechanism 4. The specific adjustment is based on:

[0095] Regardless of whether the bottles are tall or short, their bodies (excluding the neck) are always divided into two parts by the rotation center line from the second station 2 to the third station 5. The upper part is the rotation value y1, y2. The gripper device ensures that the molds at the second station 2 to the third station 5 are properly matched. Because the bottle conveyor (the fourth station 7 and the fifth station 9) is shared by all columns in the five-row bottle making machine, and the height of the conveyor belt 11 is the same, the difference hc between the body of short and tall bottles needs to be eliminated by the cantilever and bottle clamping mechanism.

[0096] Therefore, in this embodiment, before performing step 1 of the production process in embodiment 1, an adjustment step needs to be added. The specific production process steps are as follows:

[0097] Step 1: Adjustment of the cantilever clamp mechanism 4.

[0098] As described in Example 1, during the rotation of the cantilever assembly 20 driven by the power mechanism and the execution of the bottle clamping action, although the cantilever housing 38 has a fixed axis of rotation, namely the cantilever input shaft 39, the running trajectory of the cantilever housing 38 itself is a composite curve in the height and horizontal directions. When the cantilever assembly 20 performs the composite curve action, and the distance between the two gripper devices at the bottom of the bottle clamping bracket 21 and the cantilever input shaft 39 (i.e., the axis of rotation of the cantilever housing 38) is different, the adjustment of the cantilever bottle clamping mechanism 4 is actually to adjust the position of the gripper devices on both sides so that the gripper devices on both sides can smoothly complete the bottle clamping and bottle release actions at both ends of the movement curve of the cantilever housing 38. Furthermore, the adjustment of the position of the gripper devices on both sides is not an adjustment of the absolute distance in the height and horizontal directions.

[0099] The specific method for adjusting the parameters is as follows:

[0100] Let R be the center distance between the axes of the cantilever input shaft 39 and the cantilever output shaft 44, and let hc be the difference in bottle body between the tallest formed bottle and the shortest formed bottle produced by this series of forming machines.

[0101] The specific adjustment method and parameters are as follows:

[0102] Adjustment 1: Adjustment of the vertical distance of the gripper device.

[0103] The locking of the side clamping device of the second mounting base 25 is released by the positioning screw 34, so that the clamping device descends a distance of hc / 3.

[0104] Adjustment 2: Adjustment of the horizontal distance of the gripper device.

[0105] The horizontal translation distance of the gripper device at the first mounting base 33 is: R{1-cos[arcsin((hc / 6) / R)]}, while the horizontal translation distance of the gripper device at the second mounting base 25 is: 2R{1-cos[arcsin((hc / 6) / R)]}.

[0106] That is, the translation distance of the gripper device at the second mounting base 25 is twice the translation distance of the gripper device at the first mounting base 33, and the translation directions are the same. The translation of the first mounting base 33 and the second mounting base 25 is completed simultaneously under the rotation of the adjusting rod 23. Therefore, the thread pitch at the threaded connection between the adjusting rod 23 and the second mounting base 25 is twice the thread pitch at the threaded connection between the adjusting rod 23 and the first mounting base 33. Let the thread pitch at the threaded connection between the adjusting rod 23 and the second mounting base 25 be p, then the thread pitch at the threaded connection between the adjusting rod 23 and the first mounting base 33 is 2p. Therefore, when adjusting, the rotation angle of the adjusting rod 23 is R{1-cos[arcsin((hc / 6) / R)]} / p.

[0107] The cantilever assembly 20 still rotates 180°, but it exhibits a "head-up" phenomenon at the initial state of the second station 2 and a "head-down" phenomenon at the initial state of the third station 5. Therefore, vertical distance adjustment is performed as described in adjustment 1. However, due to the aforementioned "head-up" and "head-down" phenomena, the clamping center of the second station 2 is slightly offset, requiring correction. Horizontal distance adjustment is then performed as described in adjustment 2. The two clamping devices have different adjustment distances, ultimately aiming to maintain the precise centering of the clamping device at the second station 2.

[0108] Adjustment 3, adjustment of the internal cooling pipe 30,

[0109] When the cantilever assembly 20 rotates to the internal cooling process, the internal cooling pipe 30 is adjusted so that it is slightly higher than the mouth of the glass bottle 26, and the gripper does not collide with the mouth of the bottle.

[0110] The parameter adjustment is further illustrated through a specific example: As is generally known in this field, the difference in bottle height (hc) between short and tall bottles is ≤240mm. Taking the maximum value, hc=240mm, and assuming the pitches on both sides of the adjusting shaft are p=1mm and 2p=2mm, and the center distances from the second station 2 to the third station 5 and from the third station 5 to the fourth station 7 are both 250mm, i.e., R=125mm, then the specific adjustment parameters are:

[0111] Rotate the adjusting rod 23 so that it rotates 6.57 times (R{1-cos[arcsin((hc / 6) / R)]} / p), causing the gripper device at the first mounting base 33 to translate to the second station 2 by a distance of R{1-cos[arcsin((hc / 6) / R)]} = 6.57 mm. Simultaneously, the gripper device at the second mounting base 25 translates to the second station 2 by a distance of 2R{1-cos[arcsin((hc / 6) / R)]} = 13.14 mm. Release the locking of the side clamping device on the second mounting base 25 using the positioning screw 34, causing the clamping device to descend a distance of hc / 3 = 80 mm.

[0112] After the above adjustments, the clamping device maintains precise centering at the second station 2 and the third station 5, respectively.

[0113] Example 3:

[0114] The difference between this embodiment and Embodiment 1 is that the support channel 36 inside the clamp bottle support 21 is omitted. The air supply lines for the clamp bottle cylinder 27 and the internal cooling air pipe 30 are both external pipes to meet different needs such as lubrication or filtration, while reducing the processing difficulty of the clamp bottle support 21.

[0115] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
