Description

Technical Field

[0001] This invention relates to the field of glassware manufacturing equipment technology, specifically to a blowing device for heat-insulated double-layer glassware and its implementation method. Background Technology

[0002] Glassware is manufactured using the blow molding method. First, molten glass is picked up using a tube, then the surface of the molten glass is leveled and shaped into a regular oval shape for subsequent blowing. After shaping, it is pre-blown so that it can be sent to the forming mold of the glassware to be produced for blowing.

[0003] However, the following defects exist in the blowing process:

[0004] 1. The blowing process is done manually, which requires high skill from employees, is inefficient, and has low productivity.

[0005] 2. During the blowing process, since the molten glass is in a fluid state, it deforms under the action of gravity. Therefore, it is necessary to ensure that the molten glass has a regular shape during blowing. The molten glass needs to be rotated continuously to overcome the influence of gravity. Rotating while blowing places high demands on the employees and is labor-intensive. If the manual rotation is unstable, it will lead to poor shaping effect and affect the quality of the blown shape. Summary of the Invention

[0006] The purpose of this invention is to provide a blowing device and method for heat-insulated double-layer glassware, which has the advantages of simple and convenient operation, reduced labor intensity, and guaranteed blowing quality. It solves the problems mentioned in the background art, such as high labor intensity, low production efficiency, and unstable rotation leading to irregular shaping of liquid glass and poor production quality.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

The bottom end of the support frame is fixedly welded to the center of the upper end of the positioning seat. The positioning seat has expansion bolt mounting holes. The bracket is fixedly welded to the top end of the support frame.

[0012] Preferably, the rotating mechanism includes a micro motor, a turntable, and a rotating cylinder. A motor partition is welded to the center of the rotating cylinder. The micro motor is assembled inside the rotating cylinder, and its output end face is connected to the motor partition. A motor fixing rod is welded inside the rotating cylinder at the upper end of the motor partition, and the motor fixing rod is fastened to the outside of the micro motor. A rubber cover is provided at the upper end of the rotating cylinder, and the rubber cover is tightly fastened inside the rotating cylinder, with its bottom end contacting the upper end face of the micro motor. The turntable is located at the lower end of the rotating cylinder. The top end of the rotating drum is fixedly connected to the output end of the micro motor. A plug rod is fixedly welded to the output end of the rotating drum. The plug rod has a positioning hole and is inserted into the plug groove. A pin is provided on the side end of the plug rod and is inserted into the plug groove and the positioning hole. A switch hole is provided on the side end of the rotating drum. A control switch is mounted on the switch hole and is in contact with the micro motor. A blowing air pipe is movably connected to the round hole in the center of the rotating seat. The other end of the blowing air pipe is connected to the rotating drum and to the blowing equipment.

[0013] Preferably, the metal trachea is provided with a first pin positioning component and a second pin positioning component inside, the first pin positioning component and the second pin positioning component are located at both ends of the metal trachea, and the pin is inserted into the metal trachea and positioned by the first pin positioning component and the second pin positioning component.

[0014] Preferably, both ends of the first and second pin positioning members are inwardly arc-shaped, and the through holes of the first and second pin positioning members are equal to the outer diameter of the pin.

[0015] Preferably, the rear end of the metal air tube is provided with a first ring clamp and a second ring clamp, and a movable rotating rod is sleeved on the metal air tube. The movable rotating rod has a first ring groove and a second ring groove. The first ring clamp is fastened in the first ring groove, and the second ring clamp is fastened in the second ring groove. The length of the movable rotating rod is 15cm.

[0016] According to another aspect of the present invention, a method for implementing a blowing apparatus for heat-insulated double-walled glassware is provided, comprising the following steps:

[0017] S1: Insert the plug rod into the plug groove, then insert the pin into the plug groove and positioning hole to fix the rotating mechanism on the preforming device. Then, hold the movable rotating rod and the rotating cylinder, and insert the metal gas pipe into the furnace to pick up the molten glass. After picking up the molten glass, place the metal gas pipe on the upper surface of the molding mold. Press the switch button. At this time, the micro motor works to drive the turntable to rotate. The rotation of the turntable drives the rotating seat to rotate, which in turn drives the metal gas pipe to rotate, so that the molten glass on the front end of the sticking tube rolls and shapes in the molding mold. Adjust the height and angle of the sticking tube until the molten glass is shaped and the surface is smooth. Then remove the pin, remove the blowing gas pipe and pull out the rotating mechanism. At this time, insert the pin to drill a hole in the molten glass that the front end of the sticking tube contacts, so that the molten glass can be blown into shape.

[0018] S2: The metal gas tube formed by the front glass liquid is placed on the support, the rotating mechanism is installed again, the blowing gas tube is connected, and the blowing equipment is connected through the blowing gas tube. Then, the micro motor is controlled to rotate. While the micro motor drives the front material tube to rotate, air is blown through the blowing gas tube to blow the front glass liquid formed into a preform. Different rotations effectively overcome the sagging deformation caused by gravity and ensure the roundness of the blown preform.

[0019] S3: After the molten glass reaches the pre-forming roundness and the pre-forming is blown, the pre-formed molten glass at the front end of the metal air tube can be sent to the forming mold again. Continue to rotate and blow air. Maintaining rotation ensures that the molten glass is evenly stressed and overcomes the influence of gravity, thus ensuring the forming effect. The forming mold can be set according to actual production needs. After forming, add cold water to the connection end between the formed glass and the adhesive tube to cool and break it, and then remove it to complete the manufacturing of the required glassware.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The movable rotating rod of the present invention is movably assembled on the metal air pipe. When the movable rotating rod is held, the metal air pipe can rotate normally. During operation, the micro motor provides power and drives the metal air pipe to rotate through linkage, so that the glass liquid on the front adhesive tube rolls and shapes in the molding die. Compared with manual rotation, it greatly reduces labor intensity and improves molding efficiency.

[0022] 2. This invention uses a pin to drill a hole in the molten glass that contacts the front end of the adhesive tube, providing a breakthrough point during blowing to shape the molten glass. The first and second pin positioning parts define the pin in the center of the metal air tube. Both ends of the first and second pin positioning parts are inwardly arc-shaped, allowing the pin to pass smoothly through them. The through holes of the first and second pin positioning parts are equal to the outer diameter of the pin, preventing it from shaking after insertion. The hole is drilled in the center and ensures the perpendicularity of the drilled hole, resulting in uniform force on the molten glass and overcoming the influence of gravity, thus ensuring the blowing effect.

[0023] 3. In the pre-forming process of this invention, a micro motor is controlled to drive the front-end molten glass to drill holes and adjust its shape. Simultaneous air blowing is performed through the blowing pipe. With the help of manual adjustment of the height and angle of the molten glass in real time, the molten glass at the front end is blown into a pre-form. The continuous rotation effectively overcomes the sagging deformation caused by gravity, ensuring the roundness of the blown pre-form. The rotation and blowing of the molten glass are carried out by a power device instead of manual operation. During the blowing operation, the production personnel can concentrate on observing the forming state of the molten glass and adjust the blowing volume, rotation speed and angle according to the real-time forming state, thereby improving the quality of the blown forming.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To address the existing problems of high labor intensity, low production efficiency, and unstable rotation leading to irregular shaping of liquid glass and consequently poor production quality, please refer to [the relevant documentation / reference]. Figures 1-6 This embodiment provides the following technical solution:

[0033] like Figure 1-6 As shown, a blowing device for heat-insulated double-layered glassware includes a blowing device 1, a primary shaping device 2, a preforming device 3, and a rotating mechanism 4. The preforming device 3 is installed on the side of the primary shaping device 2, and the rotating mechanism 4 is assembled at the rear end of the blowing device 1. The blowing device 1 is mounted on the primary shaping device 2 and the preforming device 3.

[0034] As a further embodiment of the present invention: such as Figure 2 As shown, the air blowing device 1 includes a metal air pipe 101, a material-adhesive pipe 102, and a pin 104. The material-adhesive pipe 102 is fixedly welded to the front end of the metal air pipe 101, and the surface of the material-adhesive pipe 102 is frosted. A rotating seat 105 is provided at the rear end of the metal air pipe 101. The rotating seat 105 is fixedly welded to the metal air pipe 101. An insertion groove 1051 is opened at the lower end of the rotating seat 105, and the pin 104 is inserted into the metal air pipe 101.

[0035] By adopting the above technical solution: the frosted surface of the adhesive tube 102 at the front end of the metal gas tube 101 is used to pick up the molten glass in the furnace, and then the adhesive tube 102 at the front end of the metal gas tube 101 is placed on the molding mold 23.

[0036] As a further embodiment of the present invention: such as Figure 1 As shown, the initial shaping device 2 includes a shaping seat 21 and a cooling water tank 22. The shaping seat 21 is assembled on the rear side of the cooling water tank 22. The upper end of the shaping seat 21 is provided with a positioning slot 211, and the shaping mold 23 is mounted on the positioning slot 211 of the shaping seat 21.

[0037] By adopting the above technical solution: the function of the initial shaping device 2 is to flatten the surface of the molten glass adhered to the adhesive tube 102 and shape it into a spherical shape. The operation process is as follows: rotate the metal air tube 101, and the adhesive tube 102 at the front end will also rotate. At this time, the molten glass on the adhesive tube 102 will rotate continuously in the shaping mold 23. The shaping state of the molten glass on the adhesive tube 102 will be observed in real time. The angle and height of the metal air tube 101 will be adjusted according to the shaping state. The upper end of the shaping mold 23 will support the metal air tube 101. The height can be adjusted by moving the metal air tube 101 on the upper end surface of the shaping mold 23. The shaping angle can be adjusted by pushing or pressing the rear end of the metal air tube 101 up or down to adjust the position of the contact surface between the molten glass and the inner end surface of the shaping mold 23. After the molten glass is shaped and the surface is flattened, a hole is drilled in the molten glass at the front end of the adhesive tube 102 using the pin 104 so that the molten glass can be blown into shape.

[0038] As a further embodiment of the present invention: such as Figure 3 As shown, the preforming device 3 includes a support frame 31, a positioning seat 32, and a bracket 33. The bottom end of the support frame 31 is fixedly welded to the center of the upper end of the positioning seat 32. The positioning seat 32 has an expansion bolt mounting hole 321. The bracket 33 is fixedly welded to the top end of the support frame 31.

[0039] By adopting the above technical solution: the preforming device 3 serves to support the metal air pipe 101, and the support frame 31 is fixed to the side end of the pre-forming device 2 by expansion bolts through the expansion bolt mounting holes 321. Figure 3 The bracket 33 is V-shaped and has a smooth arc edge, which facilitates the mounting of the metal air pipe 101 and the adjustment of the angle. After the initial shaping device 2 shapes the molten glass, smooths the surface, and drills holes, the metal air pipe 101 is mounted on the bracket 33 and blown while rotating, so that the molten glass is blown into a preform. Due to the effect of gravity, it will sag. Therefore, continuous rotation can effectively overcome the sag deformation caused by gravity and ensure the roundness of the blown preform.

[0040] As a further embodiment of the present invention: such as Figure 4-6As shown, the rotating mechanism 4 includes a micro motor 41, a turntable 42, and a rotating drum 43. A motor partition 44 is welded to the center of the rotating drum 43. The micro motor 41 is assembled inside the rotating drum 43, and its output end face is connected to the motor partition 44. A motor fixing rod 45 is welded to the rotating drum 43 above the motor partition 44, and the motor fixing rod 45 is fastened to the outside of the micro motor 41. A rubber cover plate 46 is provided at the upper end of the rotating drum 43, and the rubber cover plate 46 is tightly fastened inside the rotating drum 43, with its bottom end contacting the upper end face of the micro motor 41. The turntable 42 is located at the lower end of the rotating drum 43, and its top end is fixedly connected to the output end of the micro motor 41. A plug-in rod 47 is fixedly welded to the output end of the turntable 42, and the plug-in rod 47 has a positioning hole 471, which is inserted into the plug-in groove 1051. Inside; a pin 48 is provided on the side end of the plug rod 47, and the pin 48 is inserted into the plug groove 1051 and the positioning hole 471; a switch hole 49 is provided on the side end of the rotating drum 43, and a control switch is mounted on the switch hole 49 in contact with the micro motor 41; a blowing air pipe 5 is movably connected to the round hole in the center of the rotating seat 105, and the other end of the blowing air pipe 5 is connected to the blowing equipment through the rotating drum 43; a first ring 1011 and a second ring 1012 are provided at the rear end of the metal air pipe 101, and a movable rotating rod 103 is sleeved on the metal air pipe 101. A first ring groove 1031 and a second ring groove 1032 are provided on the movable rotating rod 103. The first ring 1011 is fastened in the first ring groove 1031, and the second ring 1012 is fastened in the second ring groove 1032. The length of the movable rotating rod 103 is 15cm.

[0041] By adopting the above technical solution: when on the initial shaping device 2, after placing the adhesive tube 102 at the front end of the metal air tube 101 on the shaping mold 23, hold the movable rotating rod 103 with one hand and the rotating cylinder 43 with the other hand, and press the switch button installed on the switch hole 49. At this time, the micro motor 41 works to drive the turntable 42 to rotate. The rotation of the turntable 42 drives the rotating seat 105 to rotate, which in turn drives the metal air tube 101 to rotate, so that the glass liquid on the front adhesive tube 102 rolls and shapes in the shaping mold 23 until the glass liquid is shaped and the surface is smoothed. Then, the pin 48 is removed, the blowing air tube 5 is removed and the rotating mechanism 4 is pulled out. At this time, the pin 104 is inserted to drill a hole in the glass liquid in contact with the front end of the adhesive tube 102 so that the glass liquid can be blown into shape.

[0042] As a further embodiment of the present invention: such as Figure 2As shown, the metal trachea 101 is provided with a first pin positioning member 106 and a second pin positioning member 107. The first pin positioning member 106 and the second pin positioning member 107 are located at both ends of the metal trachea 101. The pin 104 is inserted into the metal trachea 101 and positioned by the first pin positioning member 106 and the second pin positioning member 107. Both ends of the first pin positioning member 106 and the second pin positioning member 107 are in the shape of an inner arc. The through holes of the first pin positioning member 106 and the second pin positioning member 107 are equal to the outer diameter of the pin 104.

[0043] By adopting the above technical solution: the first pin positioning member 106 and the second pin positioning member 107 are used to limit the pin 104, so that the pin 104 is located in the center of the metal gas tube 101. When drilling the glass liquid that is in contact with the front end of the adhesive tube 102, it can be drilled in the center and the verticality of the drill hole can be guaranteed. If the drill hole is skewed, the thickness of the glass liquid around the hole will be uneven during the later blowing process, which will cause the blown glass liquid to be skewed due to uneven force, requiring correction and increasing the workload. Therefore, the above setting effectively overcomes this problem. Both ends of the first pin positioning member 106 and the second pin positioning member 107 are inward arc-shaped, which allows the pin 104 to pass smoothly through the first pin positioning member 106 and the second pin positioning member 107. The through holes of the first pin positioning member 106 and the second pin positioning member 107 are equal to the outer diameter of the pin 104, so that the pin 104 will not wobble after being inserted.

[0044] To better illustrate the blowing process, this embodiment presents a method for implementing a blowing apparatus for insulated double-walled glassware, comprising the following steps:

[0045] Step 1: Insert the connector rod 47 into the connector slot 1051, and then insert the pin 48 into the connector slot 1051 and the positioning hole 471 to fix the rotating mechanism 4 onto the preforming device 3. Then, hold the movable rotating rod 103 and the rotating cylinder 43, and insert the metal gas pipe 101 into the furnace to pick up the molten glass. After picking up the molten glass, place the metal gas pipe 101 on the upper surface of the molding mold 23, and press the switch button. At this time, the micro motor 41 works to drive the turntable 42 to rotate. The rotation of turntable 42 drives the rotation of rotating seat 105, which in turn drives the metal air tube 101 to rotate, so that the molten glass on the front end of the adhesive tube 102 rolls and shapes in the molding mold 23. The height and angle of the adhesive tube 102 are adjusted until the molten glass is shaped and the surface is smoothed. Then the pin 48 is removed, the blowing air tube 5 is removed and the rotating mechanism 4 is pulled out. At this time, the pin 104 is inserted to drill a hole in the molten glass that the front end of the adhesive tube 102 contacts, so that the molten glass can be blown into shape.

[0046] Step 2: The metal air tube 101, which is formed by molding the front glass liquid, is placed on the support 33, the rotating mechanism 4 is installed again, and the blowing air tube 5 is connected. The blowing air tube 5 is connected to the blowing equipment, and then the micro motor 41 is controlled to rotate. While the micro motor 41 drives the front adhesive tube 102 to rotate, it is blown up through the blowing air tube 5, so that the front molded glass liquid is blown into a preform. The continuous rotation effectively overcomes the sagging deformation caused by gravity and ensures the roundness of the blown preform.

[0047] Step 3: After the molten glass reaches the pre-formed roundness and the pre-formed glass is blown, the pre-formed molten glass at the front end of the metal air tube 101 can be sent to the forming mold again. Continue to rotate and blow air. Keep rotating to ensure that the molten glass is evenly stressed and overcome the influence of gravity, thus ensuring the forming effect. The forming mold can be set according to the actual production needs. After forming, add cold water to the connection end between the formed glass and the adhesive tube 102 to cool and break it, and then remove it to complete the manufacturing of the required glassware.

[0048] Working principle: The metal air pipe 101 extends into the furnace and the front end of the adhesive pipe 102 picks up the molten glass. After picking up the molten glass, the metal air pipe 101 is placed on the upper end of the molding mold 23. The micro motor 41 drives the metal air pipe 101 to rotate and adjusts the height and angle of the adhesive pipe 102 so that the molten glass on the front end of the adhesive pipe 102 rolls and shapes in the molding mold 23. After shaping, the blowing air pipe 5 is removed and the rotating mechanism 4 is pulled out. The pin 104 is inserted to drill a hole in the molten glass that the front end of the adhesive pipe 102 contacts and send it to the preforming device 3. The rotating mechanism 4 is installed and the blowing air pipe 5 is connected. The blowing air pipe 5 is connected to the blowing equipment. While controlling the rotation of the adhesive pipe 102, the blowing air pipe 5 blows the molten glass that has been shaped at the front end, so that the preformed glass is blown into shape. The continuous rotation effectively overcomes the sagging deformation caused by gravity and ensures the roundness of the blown preform. After the preform is blown, it is sent to the forming mold of the glassware to be produced for blowing.

When on the initial shaping device (2), after placing the adhesive tube (102) at the front end of the metal air tube (101) on the shaping mold (23), hold the movable rotating rod (103) with one hand and the rotating cylinder (43) with the other hand, press the switch button installed on the switch hole (49), the micro motor (41) works to drive the turntable (42) to rotate, the turntable (42) rotates to drive the rotating seat (105) to rotate, so that the glass liquid on the front adhesive tube (102) rolls and shapes in the shaping mold (23) until the glass liquid is shaped and the surface is smoothed, remove the pin (48), remove the blowing air tube (5) and pull out the rotating mechanism (4), insert the pin (104) to drill a hole in the glass liquid in contact with the front end of the adhesive tube (102) so that the glass liquid can be blown into shape.

2. A double layer glassware blowing apparatus according to claim 1, wherein: The preforming device (3) includes a support frame (31), a positioning seat (32) and a bracket (33). The bottom end of the support frame (31) is fixedly welded to the center of the upper end of the positioning seat (32). An expansion bolt mounting hole (321) is provided on the positioning seat (32). The bracket (33) is fixedly welded to the top end of the support frame (31).

3. A method of implementing the apparatus for blowing the double-heat-insulated glassware according to claim 2, characterized in that: Includes the following steps: S1: Insert the plug rod (47) into the plug groove (1051), and then insert the pin (48) into the plug groove (1051) and the positioning hole (471) to fix the rotating mechanism (4) on the preforming device (3). Then, hold the movable rotating rod (103) and the rotating cylinder (43) and insert the metal gas pipe (101) into the furnace to pick up the glass liquid. After picking up the glass liquid, place the metal gas pipe (101) on the upper end of the molding mold (23) and press the switch button. At this time, the micro motor (41) works to drive the turntable (42) to rotate. The turntable (42) rotates, which drives the rotating seat (105) to rotate, which in turn drives the metal air pipe (101) to rotate, so that the glass liquid on the front end of the adhesive tube (102) rolls and shapes in the molding mold (23), and adjusts the height and angle of the adhesive tube (102) until the glass liquid is shaped and the surface is smoothed. Then, the pin (48) is removed, the blowing air pipe (5) is removed and the rotating mechanism (4) is pulled out. At this time, the pin (104) is inserted to drill a hole in the glass liquid that the front end of the adhesive tube (102) contacts, so that the glass liquid can be blown into shape. S2: The metal air pipe (101) formed by the front glass liquid is mounted on the bracket (33), the rotating mechanism (4) is installed again, the blowing air pipe (5) is connected, the blowing equipment is connected through the blowing air pipe (5), and then the micro motor (41) is controlled to rotate. While the micro motor (41) drives the front adhesive tube (102) to rotate, air is blown through the blowing air pipe (5) to make the front glass liquid formed by the front liquid blown into a preform. The continuous rotation effectively overcomes the sagging deformation caused by gravity and ensures the roundness of the blown preform. S3: When the glass liquid reaches the pre-formed roundness and blown pre-form, the pre-formed glass liquid at the front end of the metal air pipe (101) is sent to the forming mold again, and rotation and blowing are continued. The rotation is maintained to ensure that the glass liquid is subjected to uniform force and to overcome the influence of gravity, so as to ensure the forming effect. The forming mold is set according to the actual production needs. After the forming is completed, cold water is added to the connection end of the formed glass and the adhesive tube (102) to cool and break it so as to remove it and complete the manufacturing of the required glassware.
