Description

Technical Field

[0001] The utility model relates to the field of glass bottle production equipment, and particularly to a glass bottle forming system. Background Art

[0002] Glass blowing is divided into two categories. One is machine blowing, and the main machine for machine blowing is a bubble blower. Utilizing the plasticity of the glass liquid, high-pressure gas is used to blow the rotating glass raw material to form the glass raw material into shape. The other is manual blowing. In manual blowing, a blowing tube with a suitable thickness is used to pick up the glass liquid to one end of the blowing tube. The worker blows air at one end of the blowing tube to blow the glass liquid on the blowing tube into a bubble shape. Then, the glass liquid is put into a mold, and the bubble is blown into shape again.

[0003] Currently, the Chinese patent with the application number 201210594379.4 discloses a production method for 5 - 6 drops of a row type bottle making machine, including steps such as receiving and loading materials; forming the vacuum bottle mouth; reverse blowing; turning and transporting the prototype; reheating and stretching; positive blowing; clamping the bottle; cooling and transporting, etc. It also discloses a row type bottle making machine composed of 26 parts such as a primary mold mechanism, a forming mold mechanism, a core pushing mechanism, a mouth clamp, etc. In the step of turning and transporting the prototype, a glass bottle prototype needs to be obtained through the primary mold mechanism, and then the mouth of the glass bottle prototype is clamped and flipped by the mouth clamp to reach the forming mold mechanism to complete the glass bottle forming work. In this process, the requirements for clamping the bottle by the mouth clamp are relatively high. When clamping and grasping the bottle with the mouth clamp, it should not be too high, too low, or the center is not correct. If it is too high, it is easy to cause the bottle mouth to burst, black spots at the bottom of the bottle mouth, or offset mouth; if it is too low, it is easy to cause the bottle neck to burst, black spots on the bottle neck, flat bottle neck, squatting and offset bottom, and the outer diameter of the bottle body exceeding the upper limit. The position for clamping and grasping the bottle by the mouth clamp should be based on the upper plane of the mouth clamp, and it should grasp and clamp between 0.5 - 1 mm below the bottle mouth edge. At the same time, the clamping and moving in and out actions should be stable to avoid the bottle sticking due to the bottle shaking in the mouth clamp fixture of the mouth clamp. The clamping and grasping action of the mouth clamp should be based on clamping the bottle so that it does not fall. If it is too fierce, it is easy to cause the bottle neck to burst, the bottle mouth to burst, flat mouth, and flat bottle neck. The requirements for the equipment accuracy are relatively high, which increases the production cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a glass bottle forming system to simplify the difficulty of turning and transporting the prototype, thereby reducing the accuracy requirements of the equipment and the production cost.

[0005] To achieve the above object, the utility model adopts the following technical solutions: a glass bottle forming system, comprising a frame and a turntable. A feed pipe is fixedly arranged on the frame, and the feed pipe is communicated with a liquid distributor. The turntable is rotatably arranged on the frame, and a plurality of stations are evenly arranged along the center of the turntable. Each station includes a feeding unit, a transfer and blowing mechanism, and a forming unit from top to bottom. The feeding unit includes a prototype mold. A first sealing section is arranged at the lower end of the prototype mold, and an air inlet hole is arranged on the side wall of the first sealing section. The air inlet hole is communicated with compressed air. The transfer and blowing mechanism includes a housing and a gripper. The housing is rotatably connected with the turntable. A mandrel is arranged in the housing, and a through hole is arranged in the center of the mandrel. The mandrel includes an air outlet end and an air inlet end. The gripper is hinged on the mandrel. The feed pipe is arranged above the feeding unit. When the raw material enters the prototype mold, the transfer and blowing mechanism is in an inverted state. The gripper and the air outlet end block the bottom of the prototype mold, and a flash forming cavity is formed through the gap between the gripper and the air outlet end. The air inlet end is fixedly connected with an end cap, and a hollow air inlet part is arranged on the side wall of the end cap. When the transfer and blowing mechanism is in an upright state, the air inlet hole is communicated with the air inlet part.

[0006] The beneficial effect of this solution is that in this application, the prototype is directly formed on the gripper, without the need to correct the clamping position through precision instruments, which simplifies the difficulty of prototype turning and feeding. At the same time, the surface of the prototype formed in this application has a hardened glass layer, and when turning and feeding, the requirement for the turning speed is relatively low.

[0007] Further, the forming unit includes a forming mold. The forming mold includes a side mold. A second sealing section is arranged at the upper part of the side mold. A sealing part is fixed at the upper end of the housing. A rotary seal is arranged between the mandrel and the housing. When the transfer and blowing mechanism is in an inverted state, both the end cap and the sealing part are located in the second sealing section.

[0008] Beneficial effect: In the feeding stage, the second sealing section arranged on the side mold is used to block the air inlet part of the end cap, reducing the probability of glass raw material flowing into the through hole of the mandrel and blocking the through hole, and reducing the later maintenance cost.

[0009] Further, a discharging part is fixed on the rack. The discharging part is an arc-shaped plate coaxial with the turntable. A slope gradually rising in the rotation direction of the turntable is provided at the top of the arc-shaped plate; the gripper includes a clamping unit and an opening and closing unit. The clamping unit includes two symmetrically arranged gripper bodies. The two ends of the gripper body are respectively a driving end and a clamping end, and the middle is hinged to the mandrel; the opening and closing unit includes an opening and closing rod, an opening and closing plate, a first opening and closing part and a second opening and closing part. An installation groove is provided on the shell. One end of the opening and closing rod is hinged in the installation groove and abuts against the opening and closing plate, and the other end can move on the slope; the opening and closing plate is slidably arranged on the mandrel. Both the first opening and closing part and the second opening and closing part include a cylinder body and a piston rod. The piston rod divides the cylinder body into a rod chamber and a rodless chamber. The rodless chambers of the first opening and closing part and the second opening and closing part are communicated. The free ends of the cylinder body and the piston rod of the first opening and closing part are respectively hinged to the driving end. The cylinder body of the second opening and closing part is fixedly arranged on the mandrel, and the free end of the piston rod of the second opening and closing part is fixedly connected to the opening and closing plate.

[0010] Beneficial effects: During the production process of glass bottles, it is necessary to spray cooling water or demolding agent, and the humidity at the production site is relatively high. At the same time, the molten glass continuously radiates heat outward, making the temperature at the site relatively high. In a high-temperature and high-humidity environment, it is difficult to use electronic components. In this application, through the combination of pneumatic components and mechanical structures, the opening and closing of the gripper are controlled. By setting a corresponding discharging part on the rack and linking the discharging part with the opening and closing unit, the force of the turntable rotation is borrowed to complete discharging, reducing the use of electronic equipment and lowering the maintenance cost.

[0011] Further, the clamping unit further includes a connecting part and a guiding part. One end of the connecting part is fixedly connected to the gripper body, and the other end is hinged to the guiding part. The guiding part is slidably arranged on the mandrel.

[0012] Beneficial effects: Through the arrangement of the guiding part and the connecting part, the opening and closing angles of the two gripper bodies are the same, improving the controllability of the gripper.

[0013] Further, a heating part is also fixedly arranged on the rack. The heating part includes an arc-shaped heating section. An air outlet is provided on the upper surface of the arc-shaped heating section, and the air outlet is communicated with combustible gas.

[0014] Beneficial effects: By heating the glass bottle prototype with an open flame, the hardened glass layer on the surface of the glass bottle prototype is quickly heated to the molten state, improving the production efficiency of the glass bottle.

[0015] Further, the feeding pipe is arranged above the movement track of the prototype mold.

[0016] Further, a tension spring is fixed between the opening and closing plate and the mandrel.

[0017] Beneficial effects: Under the action of the tension spring, the second opening and closing member is in a contracted state, and the first opening and closing member is in an extended state, so that the clamping state of the clamping end of the gripper is kept stable, avoiding loosening during operation and affecting the forming quality of the glass bottle.

[0018] Furthermore, both the first opening and closing member and the second opening and closing member are gas springs, and the diameter of the second opening and closing member is larger than that of the first opening and closing member.

[0019] Beneficial effects: The diameter of the second opening and closing member being larger than that of the first opening and closing member means that the second opening and closing member can drive the first opening and closing member to contract a longer distance by extending a shorter distance, thus quickly completing the opening and closing work of the gripper and improving work efficiency.

[0020] Furthermore, it further includes a spraying unit. The spraying unit includes at least two groups of spray heads. The spray heads are connected to a demolding agent. The two groups of spray heads are arranged on the frame between the discharging part and the feeding pipe and respectively cool the prototype mold, the forming mold and the clamping unit.

[0021] Beneficial effects: 1. Spraying the demolding agent is beneficial for demolding; 2. Cooling the gripper, the air outlet end of the mandrel, the prototype mold and the forming mold through the demolding agent can avoid the continuous increase in the temperature of the gripper, the air outlet end of the mandrel, the prototype mold and the forming mold during continuous production, delaying the hardening time of the glass raw material and increasing the forming difficulty of the glass raw material.

[0034] Example 1

[0035] Example 1 is basically as shown in the Figures 1-10 accompanying drawings. As Figures 1-10 shown, the glass bottle forming system includes a frame, a spraying unit, a turntable and a number of working stations. In the utility model, the number of working stations is six, and each working station includes a feeding unit 21, a transfer and blowing mechanism 23 and a forming unit 22. The turntable is rotatably arranged on the frame, and the working stations are arranged on the turntable and rotate together with the turntable.

[0036] As Figure 1 shown, a heating part 13, an adjusting part 14 and a discharging part 15 are welded on the frame. The heating part 13 includes an arc heating section, an air inlet pipe, an air inlet valve and an igniter. An air outlet is arranged on the upper surface of the arc heating section. The air outlet is communicated with the air inlet pipe. A check valve is arranged between the arc heating section and the air inlet pipe. The air inlet pipe is communicated with combustible gas. In this embodiment, the combustible gas is natural gas. The air inlet valve is arranged on the air inlet pipe. The arc heating section is coaxial with the turntable. The igniter is one of a piezoelectric ceramic igniter or a pulse igniter. The ignition principle is the same as that of a natural gas stove igniter. When the air inlet valve is opened, the igniter generates an electric spark to ignite the natural gas overflowing from the air outlet. Details are not described herein.

[0037] As Figure 1 shown, the adjustment part 14 is a rod-shaped structure welded to the frame at the lower end, and the upper end is inclined close to the working station and rotatably provided with a runner (not shown in the figure). The circle where the runner is located is tangent to the rotation trajectory when the lower end of the mandrel 232 is in the vertical state.

[0038] The unloading part 15 is welded to the frame. As Figure 1 , Figure 2 shown, the unloading part 15 is an arc-shaped plate as a whole. A slope gradually rising in the rotation direction of the turntable is provided at the top, and a discharge position 152 is provided at the bottom. When the working station rotates to the position where the unloading part 15 is located along with the turntable, the working station and the slope 151 act together to disassemble the formed glass bottles on the working station, and the disassembled glass bottles are taken out through the discharge position 152.

[0039] The spraying unit includes at least two groups of spray heads. The spray heads are connected to a release agent, and the two groups of spray heads are arranged on the frame between the unloading part 15 and the feed pipe 12.

[0040] As Figure 1 shown, the turntable includes an upper-layer turntable 111, a middle-layer turntable 112, and a lower-layer turntable 113 from top to bottom. The upper-layer turntable 111, the middle-layer turntable 112, and the lower-layer turntable 113 can be an integral body or three relatively independent structures. In this embodiment, the upper-layer turntable 111, the middle-layer turntable 112, and the lower-layer turntable 113 are independent structures. The upper-layer turntable 111, the middle-layer turntable 112, and the lower-layer turntable 113 are all rotatably arranged on the frame. The feeding unit 21, the transfer and blowing mechanism 23, and the forming unit 22 are respectively arranged on the upper-layer turntable 111, the middle-layer turntable 112, and the lower-layer turntable 113. During use, the upper-layer turntable 111, the middle-layer turntable 112, and the lower-layer turntable 113 rotate at the same angular velocity to ensure that the relative positions of the feeding unit 21, the transfer and blowing mechanism 23, and the forming unit 22 within the same working station remain fixed. When the equipment installed on the upper-layer turntable 111, the middle-layer turntable 112, or the lower-layer turntable 113 needs to be repaired, the upper-layer turntable 111, the middle-layer turntable 112, and the lower-layer turntable 113 can be misaligned to leave an operating space for convenient repair.

[0041] As Figure 4 shown, the feeding unit 21 includes two groups of prototype mold bodies 211 and a prototype mold opening and closing driving part 212. The prototype mold body 211 has a semi-cylindrical structure. The two groups of prototype mold bodies 211 are combined to form a prototype mold. A prototype mold rotating part 2112 and a prototype mold hinged part 2113 are welded on the prototype mold body 211. As Figure 9As shown, a first sealing section 2114 is welded or integrally formed at the lower end of the prototype mold. In this embodiment, the first sealing section 2114 is integrally formed with the prototype mold body 211. An air inlet hole 2111 is provided on the side wall of the first sealing section 2114. The rotating part 2112 of the prototype mold is rotatably connected to the frame. The prototype mold opening and closing driving member 212 is a telescopic driving member such as an oil cylinder or a cylinder. In this embodiment, the prototype mold opening and closing driving member 212 is a cylinder. The cylinder body of the cylinder is hinged to the frame, and the output device of the cylinder is hinged to the hinged part 2113 of the prototype mold. Thus, through the expansion and contraction of the prototype mold opening and closing driving member 212, the prototype mold body 211 is driven to rotate around the connection point where the rotating part 2112 of the prototype mold is rotatably connected to the frame, completing the opening and closing work of the prototype mold. The air inlet hole 2111 is communicated with compressed air.

[0042] The transfer and blowing mechanism 23 includes a housing 231, a rotating unit, a blowing unit, and a clamping and opening / closing unit, as Figure 5 shown. An installation groove 2312 is provided on the side wall of the housing 231. Rotating shafts 2311 are welded on both sides of the housing 231. The rotating shafts 2311 are rotatably arranged on the middle layer turntable 112 and drive the housing 231 to rotate in the vertical direction through the rotating unit. A sealing part 2313 is bonded to the upper end of the housing 231.

[0043] As Figure 3 shown, the rotating unit includes a rotating motor 2372 and a driven bevel gear 2371. The rotating motor 2372 is fixed to the middle layer turntable 112 by bolts. A driving bevel gear meshing with the driven bevel gear 2371 is key-connected to the output shaft. The driven bevel gear 2371 is key-connected to the rotating shaft 2311. The rotating motor 2372 is a servo motor. During use, the driving bevel gear is driven to rotate by the rotating motor 2372, and the driving bevel gear drives the rotating shaft 2311 to rotate, thereby driving the housing 231 to rotate in the vertical direction.

[0044] The blowing unit includes a mandrel 232 and an end cap 236. The mandrel 232 is fixedly arranged inside the housing 231. The end cap 236 is threadedly connected to the upper end of the mandrel 232. A rotating seal 235 is arranged between the housing 231 and the mandrel 232. The rotating seal 235 is bonded to the mandrel 232 and fits against the inner wall of the housing 231.

[0045] As Figure 5 、 Figure 10 shown, a through hole is provided in the center of the mandrel 232. A connecting part 2321 is welded to the outer wall of the mandrel 232. The lower end is an air outlet. As Figure 10 shown, an air inlet part 2361 is provided in the middle of the end cap 236. The air inlet part 2361 is made by a hollowing process.

[0046] When the transfer and blowing mechanism 23 is in the upright state, as Figure 10As shown, both the end cap 236 and the sealing portion 2313 are located within the first sealing section 2114. At this time, the air inlet portion 2361 is in communication with the air inlet hole 2111. With the cooperation of the rotary seal 235, compressed air enters the through hole within the mandrel 232 through the air inlet hole 2111 and the air inlet portion 2361 of the end cap 236, and flows out through the air outlet to perform the blow molding operation.

[0047] The clamping and opening / closing unit includes a clamp and an opening / closing unit. The clamp includes a clamp body 2341, a connecting member 2346, and a guiding member 2342 as Figure 6 shown. The clamp body 2341 includes a driving end and a clamping end. The middle of the clamp body 2341 is hinged to the connecting portion 2321, and the two ends are respectively the driving end and the clamping end. During use, by applying force to the driving end, the clamping end is driven to open and close. When the clamping end closes, the inner side of the clamping end and the outer side of the air outlet jointly form a flash molding cavity. The upper end of the connecting member 2346 is welded to the clamp body 2341, and the lower end is hinged to the guiding member 2342. The guiding member 2342 is slidably arranged on the mandrel 232, so as to ensure that the opening and closing angles of the clamp body 2341 are the same through the restriction of the guiding member 2342.

[0048] As Figure 7 shown, the opening / closing unit includes an opening / closing plate 2343, an opening / closing rod 233, a first opening / closing member 2344, and a second opening / closing member 2345. The opening / closing plate 2343 is slidably arranged on the mandrel 232. A tension spring (not shown in the figure) is also welded or bolted between the mandrel 232 and the opening / closing plate 2343. The axis of the tension spring is parallel to the axis of the mandrel 232. The opening / closing rod 233 is rotatably arranged in the installation groove 2312. The first opening / closing member 2344 and the second opening / closing member 2345 are both telescopic members such as cylinders, oil cylinders, or gas springs. In this embodiment, both the first opening / closing member 2344 and the second opening / closing member 2345 are gas springs. The gas spring includes a spring body and a piston rod. The piston rod is slidably arranged in the spring body and divides the spring body into a rod chamber and a rodless chamber. When the volume of the rodless chamber increases, the gas spring extends. The free ends of the spring body and the piston rod of the first opening / closing member 2344 are respectively hinged to the driving end of the clamp body 2341. The spring body of the second opening / closing member 2345 is bolted to the mandrel 232, and the free end of the piston rod is welded to the opening / closing plate 2343. The rodless chambers of the first opening / closing member 2344 and the second opening / closing member 2345 are in series. Under the action of the tension spring, the second opening / closing member 2345 is in a contracted state. When the second opening / closing member 2345 contracts, the first opening / closing member 2344 extends. The diameter of the piston rod of the second opening / closing member 2345 is larger than the diameter of the piston rod of the first opening / closing member 2344 to ensure that the second opening / closing member 2345 can extend and contract a shorter distance, so that the first opening / closing member 2344 can extend and contract a larger distance.

[0049] The molding unit 22 includes a bottom mold 222 and two groups of side molds 221, asFigure 8 As shown, a cylinder is bolted to the bottom end of the bottom mold 222, and the cylinder is bolted to the frame. Thus, the bottom mold 222 is driven to move up and down by the cylinder. As Figure 10 shown, a second sealing section 2213 is provided on the upper part of the side mold 221.

[0050] The forming unit 22 includes a forming mold. The forming mold includes a side mold 221 and a bottom mold 222. A side mold rotating part 2211 and a side mold hinged part 2212 are welded to the outer side of the body of the side mold 221. The side mold rotating part 2211 is rotatably connected to the frame. The side mold hinged part 2212 is hinged with a side mold opening and closing driving part 223. The side mold opening and closing driving part 223 is a telescopic driving part such as an oil cylinder or a cylinder. In this embodiment, the side mold opening and closing driving part 223 is a cylinder. The cylinder block of the cylinder is hinged to the frame, and the output device of the cylinder is hinged to the side mold hinged part 2212. Thus, through the expansion and contraction of the side mold opening and closing driving part 223, the body of the side mold 221 is driven to rotate around the connection point where the side mold rotating part 2211 is rotatably connected to the frame, completing the opening and closing work of the side mold 221. A second sealing section 2213 is provided on the upper part of the side mold 221. A sealing part 2313 is fixed to the upper end of the housing 231. A rotary seal is provided between the core shaft 232 and the housing 231. When the transfer and blowing mechanism 23 is in an inverted state, the end cover 236 and the sealing part 2313 are both located in the second sealing section 2213. A lifting driving part 2221 is fixed to the lower end of the bottom mold 222. In this embodiment, the lifting driving part 2221 is a cylinder. The cylinder block of the cylinder is bolted to the frame, and the output shaft is welded or bolted to the bottom mold 222.

[0051] During use, as Figure 1 shown, the lower end of the push-pull rod moves from one end to the other end of the slope 151, causing the front end of the push-pull rod to rotate downward. The opening and closing plate 2343 is pushed downward through the opening and closing part 2331, thereby driving the piston rod of the first opening and closing part 2344 to move downward. Furthermore, the volume of the rodless cavity of the first opening and closing part 2344 becomes larger. Since the rodless cavities of the first opening and closing part 2344 and the second opening and closing part 2345 are in series, the increase in the volume of the rodless cavity of the first opening and closing part 2344 will inevitably cause the volume of the rodless cavity of the second opening and closing part 2345 to become smaller. Thus, the upper ends of the gripper body 2341 approach each other, and the lower ends move away from each other. Furthermore, the lower end of the gripper body 2341 opens, facilitating the removal of the formed glass bottle.

[0052] The specific implementation process is as follows:

[0053] Initial forming: The working state of the station is as Figure 9As shown, both the outer shell and the mandrel 232 are in an inverted state. The end cap 236 and the sealing part 2313 are both clamped inside the second sealing section 2213 of the forming die. The second sealing section 2213 and the rotating seal 235 block the air inlet part 2361 of the end cap 236, so that the lower end of the internal through hole of the mandrel 232 is blocked. The glass raw material falls from the feed pipe 12 and enters the prototype die through the flared opening at the upper end of the prototype die. Part of the glass raw material flows into the flash forming cavity formed by the gap between the mandrel 232 and the holder body 2341, hardens to form a flash, and is clamped between the holder body 2341 and the mandrel 232. The remaining part forms a cylinder under the action of the gravity of the glass raw material itself and the limitation of the prototype die. At the same time, the surface of the glass raw material in contact with the prototype die solidifies due to heat loss, and the prototype of the glass bottle is obtained;

[0054] Heating and melting: After the initial forming is completed, driven by the turntable, the station rotates to the heating part 13. Both the prototype die and the forming die are opened. The rotating motor 2372 drives the housing 231 to rotate, thereby driving the mandrel 232 to rotate, and further driving the transfer and blowing mechanism 23 to rotate 90 - 135°, so that the prototype of the glass bottle is horizontally or inclined downward above the heating part 13. The prototype of the glass bottle is heated by the open flame generated by the combustion of natural gas until the surface temperature of the prototype of the glass bottle rises to the same as the internal temperature of the prototype of the glass bottle, and then it leaves the heating part 13;

[0055] Adjustment and reset: After heating, the station reaches the area where the adjustment part 14 is located driven by the turntable. The transfer and blowing mechanism 23 rotates to a vertical state. When the transfer and blowing mechanism 23 cannot be in a vertical state, the lower end of the transfer and blowing mechanism 23 will push against the front end of the adjustment part 14. Driven by the adjustment part 14, the transfer and blowing mechanism 23 resumes the vertical state. At this time, the prototype die and the forming die are closed to clamp the upper and lower ends;

[0056] Forming: When the prototype die and the forming die are closed and the upper and lower ends are clamped, as Figure 10 shown, compressed air enters the inside of the end cap 236 through the air inlet hole 2111 and the air inlet part 2361, and blows and forms the prototype of the glass bottle through the through hole;

[0057] Unloading: When the hardening of the glass bottle is finished, the workstation reaches the unloading part 15 through the action of the turntable, and the transfer blowing mechanism 23 rotates 10-45 degrees, so that the roller is lifted to the slope, and the roller rolls on the slope, driving the opening and closing rod 233 to rotate, so that the opening and closing part 2331 is turned from an inclined state to a vertical state, pushing the opening and closing plate 2343 to slide downward on the core shaft 232, driving the second opening and closing piece 2345 to extend, and then driving the first opening and closing piece 2344 to contract, so that the lower end of the clamp body 2341 is unfolded, releasing the clamping of the flash, and completing the unloading work. After the unloading is completed, under the action of the tension spring, the opening and closing plate 2343 is reset, thereby driving the second opening and closing piece 2345 to reset, and then driving the clamp body 2341 to reset;

[0058] Cooling: After unloading is completed, cooling water spraying or mold release agent spraying is used to cool down the temperature of the holder body 2341 and the outlet end of the core shaft 232, reduce the temperature of the holder end during the next blowing, and reduce the hardening time of the glass raw material at the holder end.

[0059] Example 2

[0060] Embodiment 2 is basically the same as Embodiment 1, except that the blowing unit further includes a self-rotating driving structure (not shown in the figure), the self-rotating driving structure includes a turbine, a worm and a servo motor, and the core shaft 232 is rotatably arranged inside the housing 231, referring to Figure 5 The turbine is arranged on the outer wall of the core shaft 232 below the rotating seal 235, the worm is rotatably arranged on the housing 231, the worm is adapted to the turbine, the servo motor is bolted to the outer wall of the housing 231 and connected to the worm through the output shaft, so that the rotation of the servo motor drives the worm and the turbine to rotate, thereby driving the core shaft 232 to rotate in the housing 231.

[0061] The material of the end cover 236 and the clamp body 2341 can be a high-performance metal-based lubricating and wear-resistant material disclosed in the paper "Remarkable Wear Resistance in Complex Concentrated Alloys with Nanoscale Structure and Composition Fluctuations" published by the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences in the journal "Research", or other lubricating and wear-resistant materials to ensure the sealing performance and smoothness of the rotation of the end cover 236 during the rotation of the core shaft 232.

[0062] When heated and melted, the worm drives the turbine to rotate, thereby driving the core shaft 232 to rotate, so that the glass bottle prototype is heated up during the rotation process, preventing the molten glass from bending under the action of gravity.
