Description

Technical Field

[0001] The present invention relates to the technical field of glass product production, and particularly relates to a glass container production device. Background Art

[0002] Glass containers have been used until now because they are non-toxic, odorless, have good barrier properties and are transparent and beautiful. Common glass containers include wine glasses, beverage bottles, medicine bottles, cosmetic bottles, and so on. In the production of glass containers, after being made by a bottle-making machine, the glass containers are cooled and shaped, and finally sent into an annealing furnace for annealing. After annealing, the performance of the glass containers is greatly improved.

[0003] When a bottle-making machine makes a glass container, it is necessary to use clamping pliers that can be opened and closed to form a molding cavity for the glass container. When the left and right clamping pliers are opened, the glass container is separated from the left and right clamping pliers of the clamping pliers, that is, the glass container is demolded from the clamping pliers, which is convenient for taking out the glass container from the clamping pliers.

[0004] However, in actual applications, there is a situation where the clamping force is insufficient, resulting in residual materials in the formed glass container and the need to increase the grinding process. For example, taking the clamping pliers and control mechanism of a glass bottle-making machine with the patent announcement number CN202465483U as an example, the two relatively clamping pliers in this technology are the commonly used clamping pliers at present. In this technology, the opening and closing of the clamping pliers are controlled by the stroke of a cylinder. The linear motion of the cylinder realizes the opening and closing of the two clamping pliers through a linkage mechanism. However, because the connection position for controlling the clamping of the clamping pliers is on the side close to the rotation center of the clamping pliers, and there is also a complex linkage mechanism connected between the cylinder and the clamping pliers, a large thrust is required when the clamping pliers are fully locked. And this thrust comes from the cylinder, so the cylinder needs to be kept under a large pushing force for a long time, reducing the service life of the cylinder. Summary of the Invention

[0005] The present invention aims to provide a glass container production device to solve the problem in the prior art that the clamping force of the clamping pliers is insufficient and the service life of the cylinder is easily reduced in order to achieve a greater clamping force.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A glass container production device includes a frame, a turntable rotatably mounted on the frame, and a plurality of clamping mechanisms evenly distributed in the circumferential direction of the turntable. The frame is equipped with a heating mechanism for heating the clamping mechanisms, a charging pipe for injecting molten glass into the clamps, and a stamping mechanism for pressing and forming the glass container. The heating mechanism, the charging pipe, and the stamping mechanism are arranged in sequence along the rotation direction of the turntable. Each clamping mechanism includes a left clamp, a right clamp, and two pushing arms. The left clamp and the right clamp are rotatably connected, and both the left clamp and the right clamp are rotatably connected to the pushing arms. The two pushing arms are symmetrically arranged with respect to the rotation center of the left clamp and the right clamp. The clamping mechanism further includes a connecting seat. One end of the pushing arm is rotatably connected to the connecting seat, and the other end of the pushing arm is rotatably connected to the middle part of the corresponding clamp. It also includes a linear actuator for pushing the connecting seat away from or towards the rotation center of the clamp.

[0008] The principle and advantages of this solution are as follows: When using this solution, when the glass container production device produces wine glasses, multiple clamping mechanisms work simultaneously, forming a multi-station production device. The idle clamping mechanisms are closed and transferred under the heating mechanism with the turntable, and the heating mechanism preheats and heats the clamping mechanisms. After the mold is heated, the clamping mechanism is transferred under the charging pipe with the turntable, and the molten glass falls along the charging pipe into the clamping mechanism. Then, the clamping mechanism carrying the molten glass continues to rotate with the turntable and reaches under the stamping mechanism, and the stamping mechanism aligns with the mold cavity of the clamping mechanism for stamping to realize the stamping and forming of the wine glass. After the wine glass cools on the clamping mechanism, it is taken out after the clamping mechanism is opened.

[0009] In this solution, by connecting the pushing arm to the middle part of the clamp and with the setting of the connecting seat, the movement of the linear actuator pushing the connecting seat is directly converted into the rotation of the pushing arm pushing the corresponding clamp. Compared with the existing clamp structure, the number of components is streamlined; at the same time, the clamping force action point when the clamps hold each other tightly is in the middle of the clamp. Compared with the existing technology where the clamping force acts on the position of the clamp close to the rotation center, this solution is beneficial to making the clamping mechanism more tightly clamped and improving the clamping force; in addition, the acting force of the linear actuator is transmitted to the pushing arm through the connecting seat, reducing the transmission process compared with the existing technology, which is beneficial to achieving a higher clamp locking force under the same thrust of the linear actuator, and thus is beneficial to extending the service life of the linear actuator (such as a cylinder).

[0010] In addition, in this solution, since the linear actuator is fixedly installed, and the number of clamping mechanisms is multiple, and multiple clamping mechanisms are installed on the turntable, that is, when the turntable rotates, the clamping mechanisms rotate accordingly. All clamping mechanisms can only be opened after being pushed by the linearly actuators with fixed positions when rotating with the turntable. That is, this solution enables all clamping mechanisms to share one linear actuator when opening the mold, reducing the cost of the glass container production device.

[0011] Preferably, as an improvement, the pushing arm includes an adjusting sleeve and connecting rods threadedly connected to both sides of the adjusting sleeve. The thread directions of the two connecting rods and the adjusting sleeve are opposite. One connecting rod is used for rotatably connecting to the connecting seat, and the other connecting rod is used for rotatably connecting to the middle of the clamping tongs.

[0012] Beneficial effects: When adopting this solution, during the bottle-making process of glass containers, if it is found that the clamping force of the clamping tongs mechanism is insufficient or too large, the adjusting sleeve can be rotated. When the adjusting sleeve rotates, due to the opposite thread directions of the connecting rods on both sides, when the adjusting sleeve rotates, the two connecting rods approach or move away from each other. When they approach each other, the length of the entire pushing arm shrinks; when they move away from each other, the length of the entire pushing arm extends. Extending the pushing arm can help increase the clamping force, and vice versa to reduce the clamping force. This solution realizes the adjustment of the clamping force of the clamping tongs mechanism.

[0013] Preferably, as an improvement, a locking nail is threadedly connected to the adjusting sleeve. The locking nail is perpendicular to the adjusting sleeve and can abut against the outer periphery of the connecting rod. The locking nail is installed in a provided locking hole. There are multiple locking holes on the adjusting sleeve, and the multiple locking holes are evenly distributed in the circumferential direction of the adjusting sleeve.

[0014] Beneficial effects: When adopting this solution, by setting multiple locking holes, each locking hole can install a locking nail. When the adjusting sleeve needs to be rotated, all the locking nails on the locking holes are removed, and then a handle or wrench that can be inserted into the locking hole is used to rotate the adjusting sleeve, making the rotation of the adjusting sleeve very labor-saving. After the adjusting sleeve is adjusted in place, driving a locking nail into one of the locking holes can complete the position locking of the adjusting sleeve relative to the connecting rod, which not only facilitates the rotational adjustment of the adjusting sleeve but also facilitates the position locking of the adjusting sleeve after the adjustment is completed, thereby realizing the fixation of the length of the pushing arm.

[0015] Preferably, as an improvement, an annular protrusion is provided on the turntable, and a guiding seat is provided on the frame. The guiding seat is located inside the annular protrusion. The left clamping tongs and the right clamping tongs are located outside the annular protrusion. The outer edge of the guiding seat includes an arc section and a clearance section. The arc section is concentric with the turntable, and an arc-shaped channel is formed between the arc section and the inner wall of the annular protrusion. The clearance section is concave towards the center of the turntable, and a clearance space is formed between the clearance section and the inner wall of the annular protrusion. The connecting seat can be radially slidably connected to the annular protrusion. The connecting seat penetrates through the annular protrusion and a rolling body is rotatably installed at the end of the annular protrusion. The rolling body can abut against the arc section. The linear actuator is used to push the connecting seat away from the rotation center of the clamping tongs when the connecting seat moves with the turntable to the clearance section.

[0016] Beneficial effects: Through the settings of the clearance section and the arc section, when the gripper mechanism rotates to the arc section along with the turntable, the outer peripheral side wall of the arc section defines the radial displacement of the longitudinal section of the connecting seat, ensuring that the gripper mechanism always maintains the state of mechanical locking and clamping when the connecting seat is in the arc section position. There is no need for external equipment to ensure the clamping of the gripper mechanism, reducing the equipment cost. At the same time, the clamping force is not affected by external equipment, so the continuous maintenance of the clamping force is more reliable.

[0017] In addition, there are multiple gripper mechanisms in this solution, and all gripper mechanisms can rotate relative to the guiding seat. All gripper mechanisms will only be opened by the linear actuator when the connecting seat on the gripper mechanism moves to align with the clearance section, that is, all gripper mechanisms can achieve the opening of the gripper by sharing one linear actuator.

[0018] Preferably, as an improvement, the connecting seat is in a T shape. The horizontal section of the connecting seat is used for rotatably connecting the pushing arm, and the longitudinal section of the connecting seat is used for slidably connecting on the annular protrusion. The two pushing arms connected to the connecting seat are symmetrically arranged with respect to the longitudinal section, so that the movement of one longitudinal section of the connecting seat drives the two pushing arms to control the left gripper / right gripper.

[0019] Preferably, as an improvement, a transition section is provided between the clearance section and the arc section. The transition section includes a transition inclined surface and a transition arc surface. The transition inclined surface connects the clearance section and the transition arc surface, and the transition arc surface is connected to the arc section. The transition section is used for the rolling body to move from the clearance section along the transition section to the arc section.

[0020] Beneficial effects: Through the cooperative setting of the transition section, after the left gripper and the right gripper of the gripper mechanism are pushed open by the linear actuator, they can automatically push the longitudinal section of the connecting seat after moving along the transition inclined surface and the transition arc surface of the transition section, and then realize the closing of the gripper, that is, the clamping function. There is no need for an additional driving mechanism, and the clamping control of all gripper mechanisms realizes automatic clamping through the structural design of the guiding seat, reducing the cost and control difficulty of the production device.

[0021] Preferably, as an improvement, the stamping mechanism includes a lifting stamping head. A heat supplement mechanism is also installed on the machine frame. The heat supplement mechanism includes a first flame gun and a second flame gun. The heat supplement mechanism is used for heat supplementing the gripper mechanism after stamping. The first flame gun and the second flame gun are located at adjacent workstations. The first flame gun is used for heat supplementing the periphery of the mold cavity of the gripper mechanism, and the second flame gun is used for heat supplementing the center of the mold cavity directly. The gripper mechanism passes through the first flame gun first and then the second flame gun; a preliminary cooling pipe is also installed on the machine frame. The preliminary cooling pipe is located at the workstation between the stamping mechanism and the first flame gun, and the nozzle of the preliminary cooling pipe can be directly opposite to the mold cavity.

[0022] Preferably, as an improvement, the first flame gun is inclined towards the clamping mechanism, the first flame gun can rotate, and the rotation center of the first flame gun can coincide with the cavity center of the clamping mechanism directly below.

[0023] Preferably, as an improvement, the opening of the cup body of the pressed glass container faces upward, and the top surface of the cup body is flush with the top surface of the clamping mechanism or the top surface of the clamping mechanism is 3-5 mm higher than the top surface of the cup body.

[0024] Beneficial effects: In the prior art, for wine glasses with solid cup stems and cup seats, since the cup stems and cup seats extend downward from the cup body, the existing positive blowing mechanism cannot be blow-molded because the cup stems and cup seats of the glass container are solid. However, there are many problems with the method of directly stamping and pressing similar to stemmed glasses. For example, in simple stamping and pressing, it is difficult to completely press out the cup stems and cup seats, or the quality of the glass containers produced before and after pressing is inconsistent. It is necessary to make the stamped wine glasses into semi-finished products and then stretch the cup stems separately, which increases the equipment and reduces the production efficiency. Or, instead of the operation of stretching the cup stems separately, the stamping head of the stamping mechanism is placed on the wine glass being made during pressing. The stamping head and the clamping mechanism exist in the form of male and female molds. After the wine glass is completely made, the stamping head is removed from the wine glass. However, this method increases the time for placing and retrieving the stamping head, increases the process, and the stamping head cools together with the wine glass during molding, making it more difficult to cool the wine glass and reducing the production efficiency of the wine glass.

[0025] In this solution, the preliminary shaping of the wine glass is completed by the lifting stamping head, and then the preliminary cooling of the wine glass is achieved through the pipe orifice of the preliminary cooling pipe facing the cavity. Since the opening of the cup body faces upward, the cup body is quickly shaped through cooling. Then, the clamping mechanism is reheated by the rotating first flame gun, increasing the temperature of the clamping mechanism. Then, the cavity center of the clamping mechanism is reheated by the second flame gun. The cup stems and cup seats just correspond to the cavity center, enabling the raw material at the center of the bottom of the cup body to flow again towards the bottom of the cavity forming the cup stems and cup seats by being heated from inside and outside (inside is the clamping mechanism in contact with the wine glass, outside is the glass raw material of the wine glass itself). In this way, the cup stems and cup seats can be manufactured without the need for an additional stretching structure or long-term placement of the stamping head, which not only ensures the processing quality, reduces the processing cost, but also helps maintain the processing efficiency.

[0026] In addition, in this solution, since the top opening of the cup body of the glass container to be formed, i.e., the wine glass, is flush with the top surface of the clamping mechanism or the clamping mechanism is slightly higher than the cup body, after the wine glass is processed, the clamping mechanism only wraps around the outer wall of the wine glass, facilitating the mold opening of the wine glass; and the top surface of the cup body of the wine glass is relatively close to the top surface of the clamping mechanism, so that when the clamping mechanism is heated, the edge of the top surface of the wine glass will also be heated. Therefore, the raw material at the cup mouth of the wine glass will soften and become round and smooth, which is beneficial to improving the quality of the wine glass.

[0027] In addition, when adopting this solution, since the first flame gun can rotate and is inclined, one first flame gun can realize the circumferential scanning heating of the mold cavity, ensuring the uniform heating of the mold cavity by the clamping mechanism.

[0028] Preferably, as an improvement, the heating mechanism includes a circumferential heating gun and a central heating gun. Both the circumferential heating gun and the central heating gun are flame guns. The circumferential heating gun and the central heating gun are located at adjacent workstations. There are multiple circumferential heating guns, which are used to heat the periphery of the mold cavity of the clamping mechanism. The central heating gun is used to heat the center of the mold cavity. The clamping mechanism first passes through the circumferential heating gun and then through the central heating gun. A heat collecting cylinder is installed on the frame, and the heat collecting cylinder is sleeved on the central heating gun.

[0029] Beneficial effects: When adopting this solution, the circumferential heating gun is used to achieve the uniform heating of the clamping mechanism. The central heating gun makes the temperature at the center of the mold cavity relatively higher, which is beneficial to improving the fluidity of the raw material at the center of the mold cavity. At the same time, the setting of the heat collecting cylinder is beneficial to improving the heat utilization rate of the flame ejected by the central heating gun, making the temperature of the flame not easily undergo heat exchange with the outside world, thereby improving the heat utilization rate.

[0041] Embodiment

[0042] Combined with Figures 2 to 9 , a glass container production device includes a frame 10, a turntable 20 rotatably mounted on the frame 10, and a plurality of clamping mechanisms 30 evenly distributed in the circumferential direction of the turntable 20. A spray pipe 1 for cleaning the mold cavity of the clamping mechanism 30, a material spraying pipe 2 for spraying a release agent into the mold cavity of the clamping mechanism 30, a heating mechanism 3 for heating the clamping mechanism 30, a material injection pipe 4 for injecting molten glass into the clamp, a stamping mechanism 5 for pressing the glass container into shape, a preliminary cooling pipe 6 for preliminarily cooling the glass container, a first flame gun 7a for supplementing heat to the periphery of the mold cavity of the clamping mechanism 30, a second flame gun 7b for supplementing heat directly to the center of the mold cavity, and a cooling mechanism 8 are sequentially installed on the frame 10 along the rotation direction of the turntable 20.

[0043] In this embodiment, the heating mechanism 3 includes a circumferential heating gun 3a and a central heating gun 3b. Both the circumferential heating gun 3a and the central heating gun 3b are flame guns. The circumferential heating gun 3a and the central heating gun 3b are located at adjacent workstations. There are multiple circumferential heating guns 3a. In this embodiment, the circumferential heating guns 3a are fixedly installed and the number is 4. Each circumferential heating gun 3a is inclined relative to the center of the cavity and is used to heat the periphery of the mold cavity of the clamping mechanism 30. The central heating gun 3b is vertically oriented towards the mold cavity and is used to heat the center of the mold cavity. The clamping mechanism 30 first passes through the circumferential heating gun 3a and then through the central heating gun 3b. A heat collecting cylinder 3c is installed and suspended on the frame 10. The heat collecting cylinder 3c is sleeved on the central heating gun 3b so that the flame generated by the combustion of the central heating gun 3b can surround the cavity, greatly improving the heating efficiency.

[0044] The stamping mechanism 5 includes a lifting cylinder 5a and a stamping head 5b. The lifting cylinder 5a is fixed on the frame 10 (the lifting cylinder 5a is a schematic diagram in the figure). The output rod of the lifting cylinder 5a is arranged vertically for lifting. The stamping head 5b is fixedly installed at the bottom of the output rod. A connecting plate 5c is fixed on the output rod. Multiple guide rods 5d (the number of guide rods 5d in this embodiment is 3) are hung on the connecting plate 5c. A buffer plate 5e is fixed at the bottom of the guide rod 5d. The buffer plate 5e is located below the connecting plate 5c. A spring 5f is provided between the connecting plate 5c and the buffer plate 5e. The spring 5f is sleeved on the guide rod 5d. When the lifting cylinder 5a drives the output rod to move downward towards the clamping mechanism 30, the buffer plate 5e first contacts the clamping mechanism 30. As the lifting cylinder 5a gradually controls the output rod to extend downward, the connecting plate 5c on the output rod drives the spring 5f to be pressed against the buffer plate 5e. At the same time, the stamping head 5b at the bottom of the output rod also gradually inserts into the mold cavity. During this process, due to the presence of the buffer plate 5e and the spring 5f, when the stamping mechanism 5 presses downward, the buffer plate 5e first gradually compresses the clamping mechanism 30, and then the stamping head 5b inserts into the mold cavity, ensuring the stability of the stamping process. When the stamping head 5b disengages from the clamp, the buffer plate 5e is also used to gradually reduce the pressure on the clamping mechanism 30, so that the upward movement of the stamping head 5b is not sudden, thereby ensuring the stamping quality.

[0045] The opening of the cup body of the pressed glass container faces upward, and the top surface of the cup body is flush with the top surface of the clamping mechanism 30 or the top surface of the clamping mechanism 30 is 3 - 5 mm higher than the top surface of the cup body.

[0046] The first flame gun 7a is inclined towards the clamping mechanism 30, and the flame of the first flame gun 7a sprays towards the periphery of the mold cavity. The first flame gun 7a can rotate (the first flame gun 7a is driven by a separate driver to rotate), and the rotation center of the first flame gun 7a can coincide with the center of the mold cavity of the clamping mechanism 30 directly below.

[0047] The cooling mechanism 8 includes two cooling pipes, which are located at adjacent workstations, and each cooling pipe can blow cold air towards the center of the mold cavity.

[0048] Each clamping mechanism 30 includes a left clamp 31, a right clamp 32, two push arms 33, a connecting seat 34 and a base 35. The base 35 is fixedly installed on the turntable 20 by bolts. The left clamp 31 and the right clamp 32 are rotatably connected to the base 35, and the rotation centers of the left clamp 31 and the right clamp 32 are coaxial. A push arm 33 is rotatably connected to the middle of each of the left clamp 31 and the right clamp 32. One end of the push arm 33 is rotatably connected to the clamp (left clamp 31 or right clamp 32), and the other end of the push arm 33 is rotatably connected to the connecting seat 34. The two push arms 33 are symmetrically arranged with respect to the rotation center of the clamp. The distance between the two push arms 33 at the end connected to the connecting seat 34 is less than the distance between the two push arms 33 at the end connected to the clamp. The rotation center of the clamp is located within the angular space formed by the two push arms 33.

[0049] Each push arm 33 includes an adjustment sleeve 331 and connecting rods 332 threadedly connected to both sides of the adjustment sleeve 331. The thread directions of the two connecting rods 332 and the adjustment sleeve 331 are opposite. One connecting rod 332 on the same push arm 33 is used for rotatably connecting to the connecting seat 34, and the other connecting rod 332 is used for rotatably connecting to the middle of the clamp.

[0050] A locking nail 333 is threadedly connected to the adjustment sleeve 331. The locking nail 333 is perpendicular to the adjustment sleeve 331, and the locking nail 333 can abut against the outer circumference of the connecting rod 332. The locking nail 333 is threadedly installed in the locking hole 334. There are multiple locking holes 334 on the adjustment sleeve 331, and the multiple locking holes 334 are evenly distributed in the circumferential direction of the adjustment sleeve 331.

[0051] The turntable 20 is intermittently rotated by a separate driver (not shown in the figure). An annular protrusion 201 is fixed on the turntable 20. The clamp is located outside the annular protrusion 201. The connecting seat 34 is T-shaped. The horizontal section of the connecting seat 34 is used for rotatably connecting the push arm 33. The vertical section of the connecting seat 34 is radially slidably connected to the annular protrusion 201. The two push arms 33 connected to the connecting seat 34 are symmetrically arranged with respect to the vertical section. The vertical section penetrates through the annular protrusion 201 and a rolling body 341 is rotatably connected to its free end. The rolling body 341 in this embodiment is a bearing, and the inner ring of the bearing is fixed to the end of the vertical section.

[0052] A guide base 101 is fixedly installed on the frame 10. The guide base 101 is located inside the annular protrusion 201. The outer edge of the guide base 101 includes an arc segment 1011, a clearance section 1012 that is recessed towards the center of the annular protrusion 201, and a transition section 1013 located between the clearance section 1012 and the arc segment 1011. An arc-shaped channel for the rolling element 341 is formed between the arc segment 1011 and the inner wall of the annular protrusion 201. A clearance space for the radial movement of the rolling element 341 along the longitudinal section is formed between the clearance section 1012 and the annular protrusion 201. The transition section 1013 includes a transition inclined surface and a transition arc surface. The transition inclined surface connects the clearance section 1012 and the transition arc surface, and the transition arc surface is connected to the arc segment 1011. The transition section 1013 is used for the rolling element 341 to move from the clearance section 1012 along the transition section 1013 to the arc segment 1011.

[0053] After the left clamping jaw 31 and the right clamping jaw 32 are clamped and closed, the rolling element 341 moves in the arc-shaped channel and the outer ring of the rolling element 341 abuts against the outer periphery of the arc segment 1011.

[0054] A shielding disc 102 is fixedly installed above the guide base 101. The shielding disc 102 is located directly above the annular protrusion 201 and covers the top of the annular protrusion 201.

[0055] A linear actuator 40 is also fixedly installed on the frame 10. The linear actuator 40 is fixedly installed on the top of the shielding disc 102. The linear actuator 40 uses a cylinder. The end of the piston rod of the linear actuator 40 is fixedly installed with a push block 401. A guide rod 402 is also fixedly connected to the push block 401. The guide rod 402 is slidably connected to the cylinder. The sliding direction of the guide rod 402 is the same as the sliding direction of the piston rod. The axial direction of the piston rod is parallel to the radial direction of the annular protrusion 201. The push block 401 is located above the push arm 33. The push block 401 can abut against the horizontal section of the connecting seat 34. The horizontal section is located between the annular protrusion 201 and the push block 401.

[0056] The linear actuator 40 is used to push the longitudinal section of the connecting seat 34 into the clearance section 1012 through the push block 401 when the longitudinal section of the connecting seat 34 moves to face the clearance section 1012 of the guide base 101 along with the turntable 20.

[0057] In this embodiment, the glass container manufactured is Figure 1 a wine glass with a solid cup stem and a cup base as shown. The bottom surface of the cup base of the manufactured wine glass has a spherical surface that is concave towards the cup body. A curved surface protrusion that fits the bottom surface of the cup base is provided on the base 35. When the clamping jaw mechanism 30 is opened, the wine glass will be restricted by the spherical convex surface on the base 35 to ensure that the wine glass does not shake after the left clamping jaw 31 and the right clamping jaw 32 of the clamping jaw mechanism 30 are opened.

[0058] The specific process of this embodiment is as follows:

[0059] I. Mold opening and closing of the gripper mechanism 30

[0060] When this embodiment is adopted, when the gripper mechanism 30 moves with the turntable 20 to a position where the longitudinal section of the connecting seat 34 faces the clearance section 1012 of the guiding seat 101, the turntable 20 stops rotating. At this time, the linear drive 40 is activated, driving the push block 401 to act on the transverse section of the connecting seat 34, and then pushing the connecting seat 34 to move towards the center of the turntable 20 (i.e., away from the rotation center of the left and right grippers 32). The radial movement of the connecting seat 34 drives the push arm 33 to open the corresponding gripper around the rotation center of the gripper, and when the gripper mechanism 30 opens, the mold opening of the left gripper 31 and the right gripper 32 is achieved.

[0061] After the gripper mechanism 30 opens and the wine glass is taken out, the turntable 20 rotates again, and the longitudinal section of the connecting seat 34 moves towards the transition section 1013 and the arc section 1011 of the guiding seat 101. During the movement of the turntable 20, the rolling body 341 on the longitudinal section rolls along the transition section 1013 until the longitudinal section moves into the arc section 1011. During the process of the longitudinal section moving from the clearance section 1012 along the transition section 1013 to the arc section 1011, the longitudinal section of the connecting seat 34 gradually moves automatically towards the outside of the annular protrusion 201. The push arm 33 also drives the left gripper 31 and the right gripper 32 to approach each other under the movement of the connecting seat 34, and finally the gripper mechanism 30 is closed.

[0062] II. Production process of the wine glass

[0063] When this embodiment is adopted, when the gripper mechanism 30 moves with the turntable 20 to face the clearance section 1012 of the guiding seat 101, the mold opening of the gripper mechanism 30 is achieved by driving the movement of the connecting seat 34 through the linear drive 40. After the mold opening, the wine glass is taken out by the robot.

[0064] Then the turntable 20 continues to rotate, and the opened gripper mechanism 30 gradually closes under the rotation of the turntable 20. When it rotates to the next station of the mold opening and closing station (the station corresponding to the linear drive mechanism is the mold opening and closing station), the blowing pipe 1 cleans the cavity of the gripper mechanism 30. At this station, the gripper mechanism 30 is not completely closed yet, so it is convenient for the blowing pipe 1 to clean the mold cavity.

[0065] Next, the turntable 20 continues to rotate to the next station. At this station, the gripper mechanism 30 is closed, and the spraying pipe 2 blows out the mold release agent into the mold cavity to facilitate the demolding of the subsequent wine glass.

[0066] Then, the turntable 20 continues to rotate until the gripper mechanism 30 faces the heating mechanism 3. The 4 circumferential heating guns 3a of the heating mechanism 3 heat the circumference of the cavity of the gripper mechanism 30 at one station, and then the central heating gun 3b heats the center of the cavity at the next station to complete the overall heating of the gripper mechanism 30.

[0067] After that, the clamping mechanism 30 is transferred to the material injection station with the turntable 20. The material injection pipe 4 injects molten glass into the mold cavity. At the next station, the mold cavity is stamped by the stamping mechanism 5 to form a wine glass blank. In this stamping process, the cup stem and the cup base are not yet fully qualified. The clamping mechanism 30 needs to rotate with the turntable 20 to the preliminary cooling pipe 6, and the cup body is cooled by the preliminary cooling pipe 6.

[0068] After that, the turntable 20 drives the clamping mechanism 30 to the reheating mechanism. The inner and outer heating of the wine glass blank is realized by the first flame gun 7a and the second flame gun 7b of the reheating mechanism, so that the glass raw material generates a certain flow, and the cup stem and the cup base are fully formed.

[0069] Finally, the clamping mechanism 30 drives the formed wine glass to the lower part of the station with the cooling pipe, and the shaping of the wine glass is realized by injecting cold air into the mold cavity through the cooling pipe.

[0070] The entire production device relies on the intermittent rotation of the turntable 20 to complete different operations at different stations, and then realizes the fully automated production of wine glasses, with high production efficiency.

[0071] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
