Description

Technical Field

[0001] The invention relates to the field of lamp production and processing accessory devices, and more specifically to a glass raw material blow molding device for lamp processing. Background Art

[0002] The production and processing of lamps usually involves multiple steps, including design, material selection, processing and assembly. The specific steps are that the designer formulates the overall structure and appearance of the lamp, adopts the low-cost plastic bulb shell on the market, forms the bulb shell by blow molding, and then assembles it, and then conducts quality inspection on the bulb before packaging and shipment.

[0003] At present, most of the bulb shells on the market are made of plastic materials. The price of plastic bulb shells is lower than that of glass bulbs, and after breaking, it is safer to handle the broken bulbs and not easy to be scratched. However, when the plastic bulb shell is blown, it is heated at high temperature to make the plastic bulb shell in a molten and thermoplastic state. At this time, the raw materials used to make the bulb shell are extremely soft. During the cooling process of the bulb shell blow molding, the part of the bulb shell that is blown up and expanded below will gradually deform and elongate due to its own gravity. Even in the mold, it will fall and accumulate, resulting in different inner wall thicknesses of the finished product after cooling. The inner wall thickness of the elongated part of the bulb shell is smaller. When used for a long time in places with high temperatures in summer, such as Yunnan, Guizhou, Sichuan and other places in my country, the highest temperature in summer can usually reach 39 degrees Celsius, which will make the internal temperature of the bulb shell higher and higher. Due to the principle of thermal expansion and contraction of gas, the gas inside the bulb shell expands due to heat and squeezes the inner wall of the bulb shell. The position with a smaller inner wall thickness of the bulb shell is more likely to break than other positions with a larger inner wall thickness. For this reason, a glass raw material blow molding equipment for lamp processing is proposed. Summary of the invention

The water inlet cavity is connected with the circular cavity, and a circulating water pipe is also fixedly inserted at one end of the circular cavity away from the water inlet cavity. The circular cavity can be connected with the water tank through the circulating water pipe away from one end of the water inlet cavity. Rotating blades are fixedly installed on the outer surface of the blow molding ball, and the rotating blades can be driven to rotate after water is passed into the water inlet cavity. The circulating water pipe is a soft water pipe.

[0008] Furthermore, the overall shape of the rotating blade is spherical, and the rotating blade is rotatably sealed with the inner wall of the circular cavity. The rotating blade is composed of a plurality of inclined arc-shaped blades, and each of the blades is provided with a plurality of groups of guide grooves at equal intervals. The water in the circular cavity can flow through the surface of the blow-molded ball through the guide grooves.

[0009] Furthermore, a spherical blowing cavity is provided inside the blow molding ball, and four groups of slots are provided on the inner wall of the blow molding cavity. Each group of the slots is provided with an anti-distortion component that supports the blow molding raw material. Each group of the slots is fixedly connected to a bellows, and the outer end of each group of the bellows is fixedly connected to a contact plate. After each group of the bellows is contracted, the contact plate can be completely contracted into the slot, and when each group of the contact plates is contracted into the slot, the surface of the contact plate and the surface of the blow molding cavity are on the same spherical surface.

[0010] Furthermore, each group of the blow-molded balls has an inner wall provided with a chute and a flow channel that are interconnected, and the diameter of the flow channel is smaller than the diameter of the chute, and each group of the bellows has a lumen that is interconnected with the flow channel, and the chute is provided with a reset component that is used in conjunction with the bellows, and the reset component includes an airbag disposed in the chute, one end of the airbag being fixedly connected to the inner wall of the chute close to one end of the flow channel, and the other end of the airbag can be extended after the airbag is inflated.

The water flow impacts the rotating blade, and the rotating blade rotates to rotate the blow-molded but not completely cooled bulb shell inside the blow molding ball, thereby changing the center of gravity of the bulb shell, reducing the uneven thickness distribution of the inner wall of the bulb shell after cooling due to the fact that the bulb shell is still in an easily deformed state after blow molding due to its own gravity.

A conveyor belt 21 is fixedly installed on the discharge base 2, and the conveyor belt 21 is located below the material discharge chute 24. The blowing unit 12 and the blow molding machine head 11 are used in conjunction with the light bulb blow molding mold 3. A blow molding port 34 connected to the outside is provided inside the light bulb blow molding mold 3. A circular cavity 31 connected to the blow molding port 34 is provided inside the light bulb blow molding mold 3. A blow molding ball 32 is arranged in the circular cavity 31. A rotating rod 33 is rotatably installed on the inner wall of the circular cavity 31, and the blow molding ball 32 rotates in the circular cavity 31 through the rotating rod 33.

[0021] A water inlet cavity 35 is also provided inside the bulb blow molding mold 3. The water inlet cavity 35 is arranged below the blow molding port 34. A circulating water pipe 5 is fixedly inserted at one end of the water inlet cavity 35. The water tank 13 can pass water into the water inlet cavity 35 through the circulating water pipe 5. The water inlet cavity 35 is connected to the circular cavity 31.

[0022] The light bulb blow molding mold 3, the rotating blades 4 and the blow molding ball 32 can all be divided into two with the movement of the second electric guide rail 23, and the initial state of the blow molding ball 32 before and after the water enters the water inlet chamber 35 is the same. Two groups of synchronously moving second electric guide rails 23 are arranged on the first electric guide rail 22. When the two groups of second electric guide rails 23 are working, the light bulb blow molding mold 3 can be divided into two and move away from each other. The blow molding machine head 11 is provided with one group, and the blowing unit 12 is provided with two groups, and the blow molding machine head 11 is located between the two groups of blowing units 12.

[0023] A circulating water pipe 5 is also fixedly inserted into the end of the circular cavity 31 away from the water inlet cavity 35. The circular cavity 31 can be connected to the water tank 13 through the circulating water pipe 5 away from the end of the water inlet cavity 35. The outer surface of the blow ball 32 is fixedly installed with a rotating blade 4, and the rotating blade 4 can be driven to rotate after water is passed into the water inlet cavity 35. The circulating water pipe 5 is a soft water pipe.

[0024] When blow molding the bulb shell of the lamp, first start the blow molding machine head 11 on the blow molding base 1, and the blow molding machine head 11 injects the hollow tubular plastic raw material into the bulb blow molding mold 3, then the first electric guide rail 22 works to move the second electric guide rail 23 to the blowing unit 12, and aligns the blowing port 34 of the bulb blow molding mold 3 with the nozzle of the blowing unit 12 (it should be specially noted here that the blowing unit 12 is composed of an air pump and a nozzle, and the nozzle can be aligned with the blowing port 34 after the second electric guide rail 23 moves the bulb blow molding mold 3). At this time, the water tank 13 and the blowing unit 12 work (it should be specially noted here that there is a pump inside the water tank 13 to pump water out of the water tank 13), and the blowing unit 12 blows up the hollow tubular plastic raw material and expands it until it fills the entire blow molding ball 32. At the same time, the water tank 13 passes the water through the water inlet cavity 3 5 is pumped into the circular cavity 31. When water enters the circular cavity 31 through the water inlet cavity 35, the water flow will impact the rotating blades 4 and make the rotating blades 4 rotate. The rotating blades 4 will also rotate with the blow molding ball 32. After waiting for one second, the blow molding of the bulb shell is completed. At this time, the second electric guide rail 23 works to separate the bulb blow molding mold 3 and the blow molding ball 32. The bulb shell falls onto the conveyor belt 21 through the discharge chute 24, and the blow molding of the bulb shell is completed. The bulb shell inside the blow molding ball 32 will continuously rotate during the blow molding process, changing its own center of gravity, which can reduce the bulb shell during the blow molding cooling. Because the bulb shell itself is not completely cooled, it is still in an easy deformation state. The bulb shell is affected by gravity. After cooling, the inner wall thickness of the bulb shell is unevenly distributed, which effectively improves the uniformity of the inner wall thickness of the bulb shell after molding, thereby improving the quality of the bulb shell. like Figure 1As shown in the figure, the blow molding machine head 11 injects raw materials into the left light bulb blow molding mold 3, and then the first electric guide rail 22 is started to move the two light bulb blow molding molds 3 to the left. At this time, the right light bulb blow molding mold 3 is injected with raw materials by the blow molding machine head 11, and the blowing port 34 of the left light bulb blow molding mold 3 is aligned with the nozzle of the blowing unit 12 at this time. The blowing unit 12 blows air into the left light bulb blow molding mold 3 to realize the blow molding action. When both light bulb blow molding molds 3 complete this action, the left light bulb blow molding mold 3 moves downward. The second electric guide rail 23 on the left side works to separate the left light bulb blow molding mold 3, so that the light bulb shell inside the left light bulb blow molding mold 3 is discharged onto the conveyor belt 21 by its own gravity, and then the second electric guide rail 23 works to close the left light bulb blow molding mold 3, and then the first electric guide rail 22 works to move the two light bulb blow molding molds 3 to the right, at this time, the right light bulb blow molding mold 3 is aligned with the right blowing unit 12 to complete the blow molding action, and at the same time, the left light bulb blow molding mold 3 is injected with raw materials by the blow molding machine head 11; It should be noted that the cavity used for molding inside the blow-molded ball 32 can be designed in shape according to the needs of the light bulb and is not limited to a spherical light bulb.

[0025] like Figures 3 to 6 As shown, the overall shape of the rotating blade 4 is spherical, and the rotating blade 4 is rotatably sealed and installed with the inner wall of the circular cavity 31. The rotating blade 4 is composed of a plurality of inclined arc-shaped blades 41, and each blade 41 is evenly spaced to form a plurality of guide grooves 42. The water in the circular cavity 31 can flow through the surface of the blow-molded ball 32 through the guide grooves 42.

[0026] When the water tank 13 pumps water into the water inlet chamber 35 through the circulating water pipe 5, the water flow impacts the rotating blade 4 to rotate, and the water flow will enter the gap between the two blades 41 to exchange heat with the inside of the blow ball 32 to cool the inside of the blow ball 32. In the process of the rotating blade 4 rotating the blow ball 32, the blade 41 will rotate with the water flow. After the blow ball 32 rotates a circle, the space between each blade 41 will be filled with water, and the entire blow ball 32 will be cooled. At the same time, when the water flow enters between the two blades 41, the water flow between each blade 41 will enter the position between other blades 41 through the guide groove 42, so that the water flow can fill the position between every two blades 41 faster, thereby improving the cooling efficiency. Water enters the circular cavity 31 through the circulating water pipe 5, and then returns to the water tank 13 through the circulating water pipe 5. When the second electric guide rail 23 works to separate the bulb blow molding mold 3, the water in the circular cavity 31 that has not circulated to the water tank 13 will fall onto the conveyor belt 21 along with the bulb shell and thus be wasted. Since the overall shape of the rotating blade 4 is spherical, and the rotating blade 4 is rotatably sealed with the inner wall of the circular cavity 31, the fan blade 41 of the rotating blade 4 will occupy the volume inside the circular cavity 31, effectively limiting the amount of water that can enter the circular cavity 31, thereby reducing the waste of water when the bulb blow molding mold 3 is separated.

[0027] like Figure 5 , Figure 7 and Figure 8 As shown, a spherical blowing cavity 321 is provided inside the blow molding ball 32, and four groups of slots 322 are provided on the inner wall of the blow molding cavity 321. An anti-distortion component 6 for supporting the blow molding raw material is provided on each group of slots 322. A bellows 61 is fixedly connected to each group of slots 322, and a contact plate 62 is fixedly connected to the outer end of each group of bellows 61. After each group of bellows 61 is contracted, the contact plate 62 can be completely contracted into the slot 322. When each group of contact plates 62 is contracted into the slot 322, the surface of the contact plate 62 and the surface of the blow molding cavity 321 are on the same spherical surface.

[0028] When the blowing unit 12 blows air into the blowing port 34 of the bulb blow molding mold 3, the bulb shell is in the process of being blow-molded and expanded. The expanded part of the material will hang down due to its own gravity. At this time, the hanging bulb shell will fall on the contact plate 62, so that the contact plate 62 will lift up the hanging part, and along with the rotation of the bulb shell itself, it imitates the action of manually blowing the bulb, effectively solving the problem of deformation of the bulb when blow molding in a molten state.

[0029] like Figure 5 , Figure 7 and Figure 8 As shown, the inner wall of each group of blow-molded balls 32 is provided with a chute 323 and a flow channel 324 that are interconnected, and the diameter of the flow channel 324 is smaller than the diameter of the chute 323, and the interior of each group of bellows 61 is provided with a tube cavity 611 that is connected to the flow channel 324, and a reset component 7 is provided in the chute 323, and the reset component 7 is used in conjunction with the bellows 61, and the reset component 7 includes an airbag 72 arranged in the chute 323, one end of the airbag 72 is fixedly connected to the inner wall of the chute 323 near one end of the flow channel 324, and the other end of the airbag 72 can be extended after the airbag 72 is inflated, and the extendable end of the airbag 72 is fixedly connected to the conductive spring 71.

[0030] The contraction rate of the bellows 61 is the same as the expansion rate of the plastic during blow molding, and one end of the airbag 72 close to the flow channel 324 is sealed and connected to the card slot 322 .

[0031] The blow molding ball 32 is composed of two separable hemispheres. The blow molding base 1 can control the operation of the electric guide rail, the blow molding machine head 11 and the blowing unit 12 . The blow molding machine head 11 is electrically connected to the conductive spring 71 .

[0032] The inner wall of the sliding groove 323 at one end away from the flow channel 324 is elastically connected to the airbag 72 via the conductive spring 71 , and the air inlet end of the airbag 72 is in communication with the flow channel 324 .

[0033] When the conductive spring 71 is not energized, the elastic force is greater than the air pressure inside the tube cavity 611 , and when the bellows 61 is extended, the contact plate 62 contacts the material inserted into the blow molding cavity 321 .

[0034] In order to ensure that the contact plate 62 can always support the bulb shell during the blow molding process of the bulb shell, when the second electric guide rail 23 works to close the bulb blow molding mold 3, since the blowing unit 12 is not working, the conductive spring 71 is in a power-off state, and the conductive spring 71 will stretch. It should be particularly noted here that the conductive spring 71 is in a compressed state when it is energized, and the conductive spring 71 will shrink after it is energized. When current is passed through the spring, the current directions in adjacent coils of the spring are the same. According to the effect of the magnetic field on the current, parallel and directional currents attract each other, causing the coils to attract each other, thereby shrinking the spring, and the conductive spring 71 pushes the retractable end of the airbag 72 to shrink, and the gas inside the airbag 72 is discharged into the bellows 61 through the flow channel 324, and the bellows 61 is thereby stretched, causing the contact plate 62 to stretch, and when the blow molding machine head 11 injects raw materials into the bulb blow molding mold 3, the four groups of contact plates 62 will contact the hollow tubular plastic raw materials, and It plays a supporting role for the hollow tubular plastic raw material, and then the blowing unit 12 performs a blow molding action on the bulb shell inside the blow molding cavity 321. The blowing unit 12 is working, and the conductive spring 71 is in a conductive state at this time. The conductive spring 71 will gradually compress and stretch the contracted airbag 72. The airbag 72 will suck out the gas inside the tube cavity 611. At this time, the bellows 61 will gradually shrink, and the contact plate 62 will gradually approach the card slot 322 until the contact plate 62 completely enters the card slot 322. In the above process, the bulb shell is also in a gradual expansion process. Since the contraction rate of the bellows 61 is the same as the expansion rate of the plastic during blow molding, the contact plate 62 is always in a state of holding up the bulb shell. The contact plate 62 can always hold up the bulb shell during the blow molding and expansion process of the bulb shell, thereby solving the problem that the bulb shell is bent due to its own gravity during blow molding, and improving the production quality of the bulb shell. When the air blowing unit 12 is working, the conductive spring 71 is energized and contracts, so that the contact plate 62 gradually approaches the slot 322 and enters the slot 322, so that the contact plate 62 supports the expanding bulb shell, while not exerting a large pressure on the bulb shell, leaving a groove on the surface of the bulb shell and causing quality problems of the bulb shell; When the blowing unit 12 is closed, the conductive spring 71 stretches due to power failure, causing the bellows 61 to stretch and bring the contact plate 62 close to the hollow tubular plastic raw material, thereby achieving a reset effect and improving the automation effect of the bulb blow molding mold 3. When the blowing unit 12 is closed, the conductive spring 71 stretches due to power failure. If the bulb shell is stuck to the inner wall of the blow molding cavity 321, during the process of the conductive spring 71 being stretched due to power failure, the contact plate 62 will push the bulb shell stuck to the inner wall of the blow molding cavity 321 out of the blow molding cavity 321, thereby assisting in material unloading.

[0035] Usage: When blow molding the bulb shell of the lamp, first start the blow molding machine head 11 on the blow molding base 1, and the blow molding machine head 11 injects the hollow tubular plastic raw material into the bulb blow molding mold 3. Then the first electric guide rail 22 works to move the second electric guide rail 23 to the blowing unit 12, and align the blowing port 34 of the bulb blow molding mold 3 with the nozzle of the blowing unit 12. At this time, the water tank 13 and the blowing unit 12 work, and the blowing unit 12 blows up the hollow tubular plastic raw material and expands it until it fills the entire blow molding ball 32. At the same time, the water tank 13 pumps water into the circular cavity 31 through the water inlet cavity 35, so that the rotating blade 4 rotates while blowing the The ball 32 rotates, and after waiting for one second, the blow molding of the bulb shell is completed. At this time, the second electric guide rail 23 works to separate the bulb blow molding mold 3 and the blow molding ball 32, and the bulb shell falls onto the conveyor belt 21 through the discharge chute 24, and the blow molding of the bulb shell is completed. The bulb shell inside the blow molding ball 32 will continue to rotate during the blow molding process, changing its own center of gravity, which can reduce the bulb shell during blow molding cooling. Since the bulb shell itself is in an easily deformable state, the bulb shell is affected by gravity. After cooling, the inner wall thickness of the bulb shell is unevenly distributed, which effectively improves the uniformity of the inner wall thickness of the bulb shell after molding, thereby improving the quality of the bulb shell.

[0036] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
