Description

Technical Field

[0001] This invention relates to the field of flame polishing apparatus technology, and more specifically to an automated flame polishing apparatus for glass bottles. Background Technology

[0002] An automated glass bottle flame polishing device is an industrial equipment specifically designed to improve the surface finish of glass bottles (such as medicine bottles, cosmetic bottles, wine bottles, etc.) at the bottle neck or overall. It utilizes a high-temperature flame to instantly heat the glass surface, causing it to slightly melt. By leveraging the surface tension of the glass itself, it eliminates tiny cracks, burrs, and unevenness, thereby obtaining a smooth, transparent, and glossy surface.

[0003] During production, the flame polishing device still has the following problems: 1. When existing flame polishing equipment polishes glass bottles, the surface of the glass is heated at high temperature, while the internal temperature is relatively low. This temperature difference in the bottle body can easily generate internal stress, which can lead to phenomena such as cold cracking, dark cracking, or chipping during or after processing.

[0004] 2. When flame polishing square bottles, the distance from the flame nozzle differs between the flat edges and corners of the bottle's outer wall. This results in the corners receiving significantly more heat than the flat edges. This uneven heating not only creates temperature differences between different parts of the bottle but also leads to variations in polishing results. For example, the corners may be excessively melted while the flat edges are insufficiently polished, affecting the product's appearance consistency and overall quality.

[0005] 3. During the polishing process of glass bottles, the bottle body is prone to positional shift or angular deflection on the tray, deviating from the set polishing center, which leads to inaccurate flame polishing position and affects the flame polishing effect.

[0006] Therefore, it is necessary to propose an automated glass bottle flame polishing device to solve the above problems. Summary of the Invention

[0012] Preferably, the control component includes a control housing connected to a gas pipe, a conical portion is provided inside the control housing, a conical block is slidably connected inside the conical portion, and a first hydraulic cylinder is connected to the outside of the control housing, with the output end of the first hydraulic cylinder connected to the conical block.

[0013] Preferably, a square cam is connected to the top of the outer wall of the lower rotating rod. The shape of the square cam is the same as the cross-section of the bottle. A second hydraulic cylinder is connected to the inner side of the outer frame. The second hydraulic cylinder is connected to the first hydraulic cylinder, and the second hydraulic cylinder controls the extension of the first hydraulic cylinder.

[0014] Preferably, the lifting assembly includes a lifting ring connected to the bottom of the lower rotating rod, an annular frame connected to the inner side of the outer frame, a sliding groove opened on the inner ring surface of the annular frame, a moving part provided on the sliding groove, a sliding pin located in the sliding groove connected to the outer wall of the lifting ring, a guide frame connected to the bottom of the lower support, and the lifting ring slidably connected to the guide frame.

[0015] Preferably, a reset ring is connected to the outer wall of the upper rotating rod, and a one-way toothed portion is provided on the outer wall of the reset ring. A reset frame is connected to the bottom of the rotating frame, and a blind hole is provided inside the reset frame.

[0018] Compared with existing known technologies, the technical solution provided by this invention has the following significant advantages: 1. By installing heating wires and guide vanes inside the turntable frame, and in conjunction with the air supply component at the bottom, hot airflow can be introduced into the turntable frame during bottle transport. The annular hot airflow evenly surrounds the bottle from all sides, causing the overall temperature of the bottle to rise uniformly. This significantly reduces the internal stress caused by instantaneous high temperature, thereby effectively reducing the occurrence of bottle cold cracking, micro-cracks, and chipping. At the same time, it also preheats the bottle, improving the effect of the next flame polishing. Furthermore, when the turntable frame moves to the polishing nozzle position, the airflow supply channel is automatically blocked to prevent the airflow from interfering with the polishing flame, ensuring polishing efficiency.

[0019] 2. By using a square cam, a first hydraulic cylinder, a second hydraulic cylinder, and a conical block, the flame size can be controlled according to different parts of the bottle. When the flame heats the flat surface of the bottle, it remains constant; when the flame heats the corner of the bottle, it automatically reduces the flame intensity at the corner, thereby reducing the temperature difference on the bottle and ensuring that all parts of the bottle are polished by the flame, thus improving product consistency.

[0020] 3. Through the coordinated design of clamping discs, arc grooves, clamping plates, sleeves, and active rods, the clamping state can be automatically switched according to the workstation status. When the turntable moves to the polishing position, the clamping plates move outward to avoid obstructing the flame. After polishing by the nozzle, the bottle is re-clamped and precisely centered. It can release the clamp when the flame is heated and reposition and clamp when the bottle is transported, preventing the bottle from tilting or deflecting during rotation and transport, and ensuring that the bottle is always in the center position of the turntable.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] The conventional components and key load-bearing components in this case are selected in accordance with standards in terms of material selection, heat treatment process and structural dimensions to ensure that they have sufficient strength, stiffness and fatigue resistance under rated load and expected working conditions. These are all conventional design considerations well known to those skilled in the art.

[0025] Depend on Figures 1 to 9The device includes a central base 101, which is cylindrical in shape. Multiple sets of rhomboid heat-insulating components are provided on the top outer wall of the central base 101 to reduce the impact of heat on the surrounding environment. A rotating frame 102 is rotatably connected to the outer wall of the central base 101. The rotating frame 102 is externally driven by a drive structure to rotate. A circumferentially distributed turntable frame 103 is connected to the top of the rotating frame 102. A rotating disk 104 is rotatably connected inside the turntable frame 103. Multiple turntable frames 103 are fixed on top of the rotating frame 102, and the rotating disk 104 is used to hold square bottles. A heating wire 105 and guide vanes 106 are connected inside the turntable frame 103. The guide vanes 106 are inclined to guide the upward airflow. The bottom of the rotating disk 104 is connected to an upper rotating rod 107, and the bottom of the rotating frame 102 is connected to an air supply assembly. The air supply assembly is connected to the interior of the rotating frame 102. The air supply assembly intermittently supplies air to the rotating disk frame 103. When the rotating disk frame 103 moves between two adjacent flame nozzles, the air supply assembly introduces airflow into the rotating disk frame 103. When the internal airflow flows, it comes into contact with the heating wire 105, heating the airflow. The blown hot airflow flows upward, heating the bottle body. Because flame polishing causes the glass surface to reach a high temperature instantly while the internal temperature is low, internal stress is generated. The annular hot airflow evenly surrounds the bottle body from all sides, raising the bottle body temperature, improving temperature uniformity, reducing the influence of external temperature on the bottle body, and reducing the possibility of cold cracking, micro-cracks, and chipping. At the same time, it serves as a preheating function, improving the effect of flame polishing at the next nozzle position. Below the upper rotating rod 107 is a lower rotating rod 108, and a connecting assembly connects the upper rotating rod 107 and the lower rotating rod 108. The bottom of the lower rotating rod 108 is externally connected to a rotation drive structure. The turntable frame 103 on the rotating frame 102 has a heating position and a loading / unloading position. When the turntable frame 103 moves to the polishing position, the rotating disk 104 inside the turntable frame 103 rotates, thereby performing rotating flame polishing on the bottle. When it moves to the loading / unloading position, the connecting assembly disconnects the lower rotating rod 108 and the upper rotating rod 107, so that the rotating disk 104 does not rotate, so as to facilitate the loading / unloading of the bottle.

[0026] An outer frame 109 is provided on the outer side of the rotating frame 102. A gas pipe 110 is connected to the outer side of the outer frame 109. A flame nozzle is provided at the end of the gas pipe 110, and the flame emitted polishes the bottle. A control component is connected to the gas pipe 110 to control the gas supply, thereby controlling the size of the flame. A lifting component is connected to the bottom of the lower rotating rod 108. The lifting component controls the movement of the connecting component. When it moves to the polishing position, the rotating disk 104 is rotated through the connecting component. A clamping component is connected inside the rotating disk 104 to position the bottle so that the bottle is located at the center of the rotating disk 104, ensuring that the flame polishing effect of each bottle is the same and improving product consistency.

[0027] The rotating disk 104 on the rotating frame 102 is used to hold square bottles. The rotating frame 102 rotates intermittently via a drive device at the bottom. The bottles on the rotating disk 104 stop as they pass each flame nozzle in sequence. After stopping, the rotating disk 104, controlled by the bottom drive device, rotates 360 degrees, polishing the bottles with flames through the nozzles. Each flame nozzle has a different height, serving to polish different areas. For example, the nozzles are arranged sequentially from top to bottom, polishing the top first, and then the bottom. After the rotating disk 104 completes one rotation, the rotating frame 102 continues to rotate, and this cycle repeats. The side furthest from the nozzles is the loading and unloading area.

[0028] When the turntable frame 103 moves to the polishing position, the airflow blown out from the turntable frame 103 will affect the polishing flame and reduce the polishing efficiency. The following provides a structure that will not affect the flame: Specifically, the air supply assembly includes an air supply ring frame 201 connected to the bottom of the outer wall of the turntable frame 103. The bottom of the turntable frame 103 extends into the air supply ring frame 201. A through hole communicating with the air supply ring frame 201 is provided on the outer wall of the turntable frame 103, allowing airflow from the air supply ring frame 201 to enter the turntable frame 103 through the through hole. A connecting ring 202 connects multiple air supply ring frames 201. The bottom of the outer frame 109 is connected to an outer air supply ring 203 rotatably connected to the connecting ring 202. The connecting ring 202 connects multiple air supply ring frames 201 together, and the outer ring surface of the connecting ring 202 is rotatably connected to the outer air supply ring 203. The outer air supply ring 203 is fixed in position, while the connecting ring 202 rotates with the air supply ring frame 201. The inner side of the outer air supply ring 203 has equally spaced air supply slots 204, located between adjacent nozzle positions. The bottom of the outer frame 109 is connected to an air supply pipe 205 that communicates with the air supply slots 204. (Reference) Figure 3When the air supply ring 201 and connecting ring 202 rotate to the nozzle position, the hole on one side of the air supply ring 201 is located between the two air supply slots 204 and is not connected to the air supply slots 204, thus blocking the airflow supply to the turntable 103. When the air supply ring 201 rotates to correspond with the air supply slots 204, the airflow in the air supply slots 204 will enter the turntable 103 through the air supply ring 201. During flame polishing, the airflow supply is blocked, and as the square bottle is conveyed to the next station, hot airflow is blown out from the bottom to heat the bottle body.

[0029] When the turntable frame 103 moves to the loading / unloading position, the rotating disc 104 will affect the loading / unloading. The following provides a structure to disconnect the upper rotating rod 107 from the power structure: Specifically, the connecting assembly includes an upper gear disc 301 and a lower gear disc 302. The opposing sides of the upper gear disc 301 and lower gear disc 302 are provided with meshing teeth, allowing the upper gear disc 301 and lower gear disc 302 to mesh together for power transmission. The upper gear disc 301 is connected to the bottom of the upper rotating rod 107, and the top of the lower rotating rod 108 is connected to a disc frame 303. The lower gear disc 302 is slidably connected to the inside of the disc frame 303. The inside of the disc frame 303 is provided with a limiting structure, allowing the lower gear disc 302 to slide only up and down within the disc frame 303. The lower gear disc 302 and the disc frame 303 are connected by a spring. Even if the teeth of the upper gear 301 and the lower gear 302 are not aligned, the lower gear 302 can be retracted into the disc holder 303 by the compression of the spring. When the disc holder 303 rotates, the lower gear 302 will re-engage with the upper gear 301 under the action of the spring, thereby improving the meshing efficiency of the upper gear 301 and the lower gear 302.

[0030] Each lower rotating rod 108 requires a drive structure to control the rotation of the rotating disk 104. However, setting multiple drive structures not only increases the difficulty of control but also leads to asynchronous rotation. The following provides a structure for controlling the rotation of multiple rotating disks 104: Specifically, a spline portion is provided on the outer wall of the lower rotating rod 108, and a spline sleeve 304 is splinedly connected to the outer wall of the lower rotating rod 108. A lower support 305 is connected to the rotating frame 102, and the lower support 305 rotates synchronously with the rotating frame 102. The spline sleeve 304 is rotatably connected to the lower support 305, and its position on the lower support 305 is fixed, allowing only rotation to drive the internal lower rotating rod 108 to rotate. The lower rotating rod 108 can slide up and down within the spline sleeve 304. A sprocket 306 is connected to the bottom of the outer wall of the spline sleeve 304. Multiple sprockets 306 are connected by a transmission chain 307. When the transmission chain 307 rotates, it drives multiple sprockets 306 to rotate. The sprockets 306 drive the lower rotating rod 108 to rotate via the spline sleeve 304. The lower rotating rod 108 drives the upper rotating rod 107 at the top to rotate through the meshing of the upper gear plate 301 and the lower gear plate 302, thereby driving the rotating disk 104 to rotate. A rotary drive motor 308 is connected to the lower support 305. One of the spline sleeves 304 and the rotary drive motor 308 are connected via a chain drive structure 309. The chain drive structure 309 consists of sprockets 306 and a chain; this is a mature existing structure and will not be described in detail here. The rotary drive motor 308 drives one of the spline sleeves 304 to rotate via the chain transmission structure 309. The spline sleeve 304 drives the other sprockets 306 to rotate via the bottom sprocket 306 and the transmission chain 307, thus driving multiple sprockets 306 to rotate synchronously. To improve the contact between the transmission chain 307 and the sprockets 306, a tensioning wheel is connected to the lower bracket 305 to increase the wrap angle of the transmission chain 307. The tensioning wheel structure is a mature existing structure and will not be described in detail here.

[0031] Because the distances between the flat surfaces and the four corners of the square bottle's outer wall and the flame nozzle are different, the corners are subjected to a greater flame impact during flame polishing than the flat surfaces. This not only creates a temperature difference between the corners and flat surfaces but also results in inconsistent flame polishing effects, affecting the bottle's quality. The following structure provides a way to ensure that each location receives the same flame polishing effect: Specifically, the control assembly includes a control housing 401 connected to the gas pipe 110. The control housing 401 contains a conical portion 402, and its interior has slots for connecting the conical portion 402 and the gas pipe 110. This allows combustible gas to enter the conical portion 402 and then flow into another section of the gas pipe 110, subsequently forming a flame from the nozzle. A conical block 403 is slidably connected within the conical portion 402. By controlling the distance between the conical block 403 and the conical portion 402, the amount of combustible gas entering is controlled, thereby adjusting the flame size. A first hydraulic cylinder 404 is externally connected to the control housing 401, and the output end of the first hydraulic cylinder 404 is connected to the conical block 403. The distance between the conical block 403 and the conical portion 402 is controlled by the extension amount of the first hydraulic cylinder 404. In one embodiment, a detection structure is provided on the outer frame 109. When a corner of the cylinder is detected, the first hydraulic cylinder 404 is extended to reduce the supply of combustible gas.

[0032] The detection structure set on the outer frame 109 to detect the state of the bottle is not only easily affected by the high temperature of the flame, but also the transparent bottle will affect the detection accuracy. The following is a structure for automatically controlling the extension of the first hydraulic cylinder 404: Specifically, a square cam 405 is connected to the top of the outer wall of the lower rotating rod 108. The shape of the square cam 405 is the same as the cross-section of the bottle. The lower rotating rod 108 will drive the square cam 405 to rotate. At the same time, the top will drive the square bottle located on the rotating disk 104 to rotate through the connecting component. At this time, the angle between the square bottle and the square cam 405 is the same. A second hydraulic cylinder 406 is connected to the inner side of the outer frame 109. The second hydraulic cylinder 406 is connected to the first hydraulic cylinder 404. The second hydraulic cylinder 406 controls the extension of the first hydraulic cylinder 404. When the corner of the square cam 405 contacts the extension rod of the second hydraulic cylinder 406, it presses the extension rod into the second hydraulic cylinder 406. At this time, the hydraulic oil in the second hydraulic cylinder 406 enters the first hydraulic cylinder 404, causing the extension end of the first hydraulic cylinder 404 to extend, thereby controlling the size of the flame. The first hydraulic cylinder 404 and the second hydraulic cylinder 406 have internal spring structures for resetting. The initial position of the extension end of the first hydraulic cylinder 404 is the retracted state; the initial position of the extension end of the second hydraulic cylinder 406 is the extended state. The extension ends of the first hydraulic cylinder 404 and the second hydraulic cylinder 406 are also called the actuating ends. The hydraulic cylinder structure is a mature existing structure and will not be described in detail here.

[0033] When the turntable frame 103 moves to the polishing position with the flame nozzle, the upper rotating rod 107 and the lower rotating rod 108 need to be connected to control the rotation of the turntable 104; after passing the nozzle position, it will return to the disconnected state, requiring timely action. The following provides a structure that automatically controls the up-and-down movement of the lower rotating rod 108 as it rotates: Specifically, the lifting assembly includes a lifting ring 501 connected to the bottom of the lower rotating rod 108, which drives the lower rotating rod 108 to move up and down. An annular frame 502 is connected to the inner side of the outer frame 109. A sliding groove 503 is formed on the inner annular surface of the annular frame 502. A moving part is provided on the sliding groove 503, facing upwards. The position of the moving part on the sliding groove 503 corresponds to the position of the nozzle. A sliding pin located within the sliding groove 503 is connected to the outer wall of the lifting ring 501. When the lifting ring 501 moves to the moving part of the sliding groove 503, it drives the lower rotating rod 108 to move upwards via the sliding pin within the sliding groove 503. A guide frame 504 is connected to the bottom of the lower support 305, and the lifting ring 501 is slidably connected to the guide frame 504. The guide frame 504 is connected to the bottom of the lower support 305 and moves together with the lower rotating rod 108. The function of the guide frame 504 is to restrict the lifting ring 501 to only move up and down, preventing the lifting ring 501 from rotating. In one embodiment, the guide frame 504 is configured as a guide optical axis or a slide rail structure to restrict the lifting ring 501 to only move up and down.

[0034] When the lifting ring 501 is located in the sliding groove 503, the height of the square cam 405 is lower than that of the second hydraulic cylinder 406. When the lifting ring 501 moves into the moving part through the sliding pin, the square cam 405 will move upward with the lower rotating rod 108. At this time, the square cam 405 will be on the same plane as the second hydraulic cylinder 406, and the rotating square cam 405 will contact the second hydraulic cylinder 406.

[0035] When the lower gear 302 and the upper gear 301 separate, the rotating disk 104 inside the turntable frame 103 will rotate due to the influence of the flame. When the rotating disk 104 deflects, it will affect the reconnection of the connecting components and also cause an angle between the square bottle and the square cam 405. The following provides a structure that allows the rotating disk 104 to reset when the lower gear 302 and the upper gear 301 disengage, thus avoiding deflection: Specifically, a reset ring 505 is connected to the outer wall of the upper rotating rod 107. The outer wall of the reset ring 505 has a one-way toothed portion 506. The bottom of the rotating frame 102 is connected to a reset frame 507, and the reset frame 507 is fixed in position on the rotating frame 102. In one embodiment, the reset frame 507 is connected to the bottom of the gas supply ring frame 201. The reset frame 507 has a blind hole inside, and a push rod 508 is slidably connected in the blind hole. The push rod 508 has a certain length and can penetrate to the lowest position between two adjacent one-way toothed portions 506. The push rod 508 and the blind hole are connected by a spring. The spring is compressed, pushing the push rod 508 outwards so that the bottom of the push rod 508 is always in contact with the one-way toothed portion 506. A ball bearing is connected to the bottom of the push rod 508, which contacts the one-way toothed portion 506, changing the sliding contact into a rolling contact and reducing friction. When the upper gear 301 and lower gear 302 disengage, the push rod 508, under the pressure of the top spring, applies downward pressure to the upper surface of the one-way toothed portion 506. Because the one-way toothed portion 506 has an inclined surface, the reset ring 505 rotates. When the push rod 508 is at its lowest position on the reset ring 505, the reset ring 505 stops. Since the one-way toothed portion 506 is toothed, its lowest position is located between two one-way toothed portions 506.

[0036] The number of unidirectional teeth 506 is the same as the number of corner teeth on a square bottle. For example, when the bottle body is square, there are four unidirectional teeth 506. The lowest position of two adjacent unidirectional teeth 506 corresponds to the corner of the bottle body, thus serving to position the bottle body. (Reference) Figure 5 In the diagram, the black line segment with the arrow indicates the rotation direction of the upper rotating rod 107. When the upper rotating rod 107 drives the reset ring 505 to rotate normally, the push rod 508 is pressed into the blind hole under the action of the one-way toothed part 506. After passing through each one-way toothed part 506, it will re-extend, and this cycle continues, providing a one-way rotation function without causing jamming. During separation, under the action of the push rod 508, the reset ring 505 will reverse at a certain angle to achieve positioning.

[0037] In another embodiment, the unidirectional toothed portion 506 is a toothed portion with a double arc at the top. In this case, the lowest point is still located between two adjacent unidirectional toothed portions 506. The downwardly pressing push rod 508 will eventually be located between two toothed portions. The two adjacent toothed portions correspond to the sharp corners of the bottle body, thus also having a positioning function.

[0038] When the square bottle shifts or rotates on the rotating disk 104, it will deviate from the square cam 405, thus affecting the flame polishing effect. The following provides a structure for centering the bottle: Specifically, a clamping disk 601 is rotatably connected inside the rotating disk 104. The clamping disk 601 has evenly distributed circumferential arc-shaped grooves 602, the arc of which is the same as the curvature of the centrifugal blades on a centrifugal fan, forming a centrifugal shape. A clamping groove 603 is formed at the top of the rotating disk 104. The clamping assembly includes a clamping plate 604 located above the rotating disk 104, made of high-temperature resistant material. In one embodiment, the clamping plate 604 is equipped with rollers to accommodate the movement of the bottle. A sliding pin is slidably connected to the bottom of the clamping plate 604 within the arc-shaped grooves 602 and the clamping groove 603. When the clamping disk 601 rotates, it drives the sliding pin to slide within the clamping groove 603, thereby controlling the movement of the clamping plate 604. By moving multiple clamping plates 604, the bottle is positioned at the center of the rotating disk 104, while maintaining the angle of the square bottle to prevent tilting or deflection. The bottom of the clamping disk 601 is connected to a sleeve 605 located inside the upper rotating rod 107. A spiral groove 606 is formed on the inner side of the sleeve 605. The top of the lower rotating rod 108 is connected to an active rod 607 extending into the sleeve 605, rotatably connected to the top of the lower rotating rod 108. A sliding pin is connected to the outer wall of the active rod 607, located within the spiral groove 606. When the active rod 607 moves up and down, the sliding pin on the active rod 607 slides within the spiral groove 606, thereby driving the sleeve 605 to rotate. The rotation of the sleeve 605 depends only on the height position of the active rod 607, regardless of whether the upper rotating rod 107 is rotating. When the active rod 607 is at the top, the rotating clamping disc 601 causes the clamping plate 604 to be in the open state; when the active rod 607 is at the bottom, the movement of the sliding pin in the spiral groove 606 causes the clamping disc 601 to rotate, thereby causing multiple clamping plates 604 to move towards the middle position, thereby clamping and positioning the bottle.

[0039] Since the moving part on the sliding groove 503 corresponds to the nozzle, the lower rotating rod 108 will drive the driving rod 607 to move upward whenever it moves to the nozzle position. When the turntable frame 103 moves to the nozzle position, the driving rod 607 moves upward, and the rotating clamping plate 601 will cause the clamping plate 604 to move outward to avoid the clamping plate 604 affecting the flame; after passing the nozzle, the driving rod 607 will move downward, at which time the clamping plate 604 moves towards the bottle body to re-clamp and reposition the bottle body, and this process is repeated. It has the function of releasing the clamp when the flame is heating and repositioning and clamping when the bottle body is being transported.

[0040] The rotating frame 102 needs to rotate on the central base 101 to transport the bottles. The following describes a structure for driving the rotating frame 102: Specifically, a chassis is connected to the bottom of the central base 101, providing support. A rotary motor 111 is connected to the chassis. The rotary motor 111 and the rotating frame 102 are connected via a worm gear transmission structure 112, which consists of a worm wheel and a worm. The rotary motor 111 drives the rotating frame 102 to rotate through the worm gear transmission structure 112.

[0041] To prevent the heat from the nozzle from affecting the loading and unloading position, a heat shield 113 is connected to the top of the outer frame 109, and the bottles are loaded and unloaded by the loading and unloading machine.

[0042] In use, the feeding machine places the bottle on the rotating disk 104. The rotary motor 111 drives the rotating frame 102 to rotate on the central base 101 through the worm gear transmission structure 112. When the rotating disk 104 rotates to the position of the nozzle, the sliding pin on the lifting ring 501 moves into the moving part of the sliding groove 503, causing the lower rotating rod 108 and the active rod 607 to move upward. At this time, the connecting component at the top of the lower rotating rod 108 will be connected together. The lower rotating rod 108 will then drive the upper rotating rod 107 to rotate. The rotary drive motor 308 drives multiple sprockets 306 to rotate through the transmission chain 307. The sprockets 306 drive the rotating disk 104 to rotate through the spline sleeve 304. The flames emitted by the nozzle polish the bottle on the rotating disk 104.

[0043] The lower rotating rod 108 drives the square cam 405 to rotate. The outer wall of the square cam 405 contacts the second hydraulic cylinder 406. The shape of the outer side of the cam compresses the extended end of the second hydraulic cylinder 406, thereby controlling the extension of the first hydraulic cylinder 404. This controls the size of the flame to fit the edges and corners of the bottle.

[0044] After the rotating disk 104 completes one revolution, the rotating frame 102 continues to rotate. At this time, the lower rotating rod 108 moves downward, and the connecting assembly disconnects the lower rotating rod 108 from the upper rotating rod 107. The downward-moving top rod 508 causes the clamping plate 604 to move towards the center position, repositioning the bottle body, and then moving it to the next polishing station. When it reaches the unloading position, the bottle body is removed by the unloading machine.

[0045] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
