Abstract
Description
Technical Field
[0001] This invention relates to the field of glass bottle processing technology, and more specifically, to a device for processing decorative holes in glass bottles to reduce the effects of sagging. Background Technology
[0002] Glass wine bottles are widely used in the packaging and storage of alcoholic beverages such as baijiu and huangjiu due to their advantages including good chemical stability, excellent sealing, controllable light transmission, and recyclability. Most existing glass wine bottles are made of soda-lime glass through a blowing process. The molded bottle is mainly composed of the bottle mouth, bottle shoulder, bottle body and bottle bottom. After filling, it is sealed with a bottle cap to preserve the wine.
[0003] Most existing glass bottles are made of soda-lime-silica glass and are mass-produced by blow molding using a row-type bottle-making machine. The production process is as follows: raw materials are mixed and melted into molten glass in a tank furnace at high temperature; a feeder cuts the molten glass into droplets of fixed weight, which fall into the initial mold and are then blown with air to form hollow bubbles; the bubbles are transferred to the forming mold, where high-pressure air is used to press the glass into the mold cavity to obtain the bottle blank.
[0004] To enhance the competitiveness of glass wine bottles, a more distinctive design is needed. Therefore, decorative holes are set on the glass wine bottles, with the holes extending through the glass to maintain the airtightness of the glass wine bottles.
[0005] However, in the production of glass bottles with decorative holes, conventional mold blowing requires the design of a column corresponding to the decorative hole at the mold. The decorative hole is created within the column by occupying its space. However, because air is blown from the bottle mouth, the droplet splits into two streams at the column, then merges at the bottom of the mold, creating a glass wall between the column and the mold bottom. To address this, a technical optimization is proposed: blow-blowing is performed on a glass bottle without decorative holes. After the bottle is formed, while the glass is still unhardened, a punch is used to press out the hole. However, it was found that due to the viscosity of the glass droplet, it cannot be directly broken off. A portion of the glass wall must remain within the decorative hole, which is then removed later to complete the decorative hole processing.
[0006] However, because the glass wall formed by this method is relatively thick, cutting it is more troublesome and requires further processing of the cut area. Therefore, the punch can be improved by setting a groove in the middle of the punch, resulting in a glass wall that is thin at the periphery and bulging in the middle, which can reduce the connection between the glass wall and the glass bottle inside the decorative hole. However, due to the influence of gravity, the bulging part in the middle of the glass wall will droop downwards, causing it to stick to the glass bottle, thus failing to achieve the goal of optimizing the cutting operation. Summary of the Invention
[0007] To address the aforementioned problems, this invention provides a glass bottle decorative hole processing device that reduces the impact of sagging, thereby minimizing glass wall sagging during processing.
[0008] This invention is achieved through the following technical solution: a glass bottle decorative hole processing device that reduces the effect of sagging, including a base, two mold blocks slidably connected on the base, each mold block having a mold groove, a driving component for driving the mold blocks to close on the base, and processing holes on both sides of the mold blocks; Each mold block is equipped with a first telescopic rod. A probe rod is fixedly connected to the output shaft of the first telescopic rod. A recess is provided on the side of the probe rod away from the first telescopic rod. The probe rod is used to insert into the processing hole to squeeze the glass bottle and produce a glass wall that is thick in the middle and thin at the edges. A hole is provided in the middle of the recess, and a push rod is slidably connected in the hole. A second telescopic rod is provided on the probe rod to drive the push rod to slide in the hole. A consumable rod is detachably connected to the side of the push rod away from the second telescopic rod. The consumable rod is used to insert into the middle of the glass wall and support the glass wall under the drive of the push rod.
[0009] Furthermore, the depth of the recessed edge is less than the depth of the recessed center.
[0010] Furthermore, a conical receiving pit is provided in the middle of the depression, and the depth of the receiving pit is less than the insertion depth of the probe rod.
[0011] Furthermore, the consumable rod is made of glass, and a guide section is provided at the end of the consumable rod away from the top rod.
[0012] Furthermore, the end of the push rod near the consumable rod is detachably connected to the consumable rod via an electric suction cup.
[0013] Furthermore, a filling groove is provided on one side of the probe, and the filling groove is connected to the hole.
[0014] Furthermore, the end of the consumable rod away from the flow guide is provided with a snap-fit groove, and a metal part is detachably snapped into the snap-fit groove. The metal part includes a sheet body, and an elastic snap-fit member is fixedly connected to the sheet body. The elastic snap-fit member is used to snap into the snap-fit groove.
[0015] Furthermore, the end of the push rod near the consumable rod is detachably connected to the consumable rod via an electromagnet.
[0016] Furthermore, the mold block is equipped with a feeding component, which includes a box body. The bottom of the box body is provided with a release port, and the box body is provided with a storage cavity for stacking consumable bars. The end of the box body near the release port is provided with an electric release door, and the end of the box body near the release port is provided with an electric clamping assembly. The electric clamping assembly and the electric release door are spaced apart by the height of one consumable bar.
[0017] Furthermore, a buffer pad is provided inside the hole, and the position of the buffer pad corresponds to the filling groove.
[0018] The technical solution of the present invention has at least the following beneficial effects: This solution is used to process decorative holes in glass bottles. Two mold blocks will close together, and the mold groove will restrict the shape of the glass bottle, thereby restricting the droplets entering the closed mold blocks. This allows the droplets to form the general appearance of the glass bottle after blowing. At this time, since the probe rod has not been inserted, the decorative holes have not yet been formed on the glass bottle that has only been blown.
[0019] Driven by the first telescopic rod, the probe can penetrate into the mold block and press the glass bottle that has not yet solidified, pressing out symmetrical recesses on both sides of the glass bottle. As the pressing continues, the last two recesses meet together, forming a glass wall at the junction. Because the probe is designed with a recess for optimization, the connection between the glass wall and the glass bottle is thinner, while the middle of the glass wall is thicker, making it easier to cut away the glass wall in subsequent processing, so that the two recesses on both sides can be connected to form a through decorative hole.
[0020] In this solution, after the glass wall is formed, a sizing rod is driven into the middle of the glass wall using a top rod. The sizing rod is a rigid structure. After being placed into the glass wall, the thick molten glass in the center of the glass wall will adhere to the sizing rod through adhesion, thereby overcoming the problem that the molten glass accumulates due to the depression, causing it to flow downwards under gravity and stick to the glass bottle.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0026] The following detailed description illustrates the specific implementation methods: Example 1 As attached Figures 1-7 As shown, a glass bottle decorative hole processing device for reducing the effect of sagging includes a base 1, two mold blocks 2 are slidably connected on the base 1, each mold block 2 is provided with a mold groove 3, the base 1 is provided with a driving component 4 for driving the mold blocks 2 to close, the driving component 4 is a hydraulic cylinder, and processing holes 5 are provided on both sides of the mold blocks 2.
[0027] Each mold block 2 is equipped with a first telescopic rod 6, which is a cylinder. A probe rod 7 is fixedly connected to the output shaft of the first telescopic rod 6. A recess 8 is provided on the side of the probe rod 7 away from the first telescopic rod 6. The depth of the edge of the recess 8 is less than the depth of the center of the recess 8. A conical receiving pit 14 is provided in the middle of the recess 8. The depth of the receiving pit is less than the insertion amount of the probe rod 7. The probe rod 7 is used to insert into the processing hole 5 to squeeze the glass bottle and produce a glass wall 9 that is thick in the middle and thin at the edges.
[0028] A hole 10 is provided in the middle of the recess 8. A push rod 11 is slidably connected in the hole 10. A second telescopic rod 12 is provided on the probe rod 7 to drive the push rod 11 to slide in the hole 10. The second telescopic rod 12 is a cylinder. A consumable rod 13 is detachably connected to the side of the push rod 11 away from the second telescopic rod 12. The end of the push rod 11 near the consumable rod 13 is detachably connected to the consumable rod 13 through an electric suction cup. The consumable rod 13 is made of glass. A guide part 15 is provided at the end of the consumable rod 13 away from the push rod 11. The consumable rod 13 is used to insert into the middle of the glass wall 9 and support the glass wall 9 under the drive of the push rod 11.
[0029] This embodiment is used for processing decorative holes on glass bottles. In the early stage of processing, as with conventional techniques, the two mold blocks 2 are closed to create a cavity with the same shape as the target glass bottle without decorative holes, and the shape of the glass bottle is restricted by the mold groove 3. Subsequently, the droplet entering the closed mold block 2 is restricted by the mold groove 3, so that the droplet can form the approximate appearance of the glass bottle after blowing. At this time, since the probe 7 has not been inserted, the decorative holes have not yet been formed on the glass bottle that has only been blown.
[0030] To form the decorative hole, the probe 7, driven by the first telescopic rod 6, extends into the mold block 2, pressing down on the still-unsolidified glass bottle. Symmetrical recesses are pressed into both sides of the bottle. As the pressing continues, the last two recesses merge, creating a glass wall 9 at the junction. Because the probe 7 has an optimized recess 8, the connection between the glass wall 9 and the bottle is thinner, while the middle section of the glass wall 9 is thicker. This facilitates further processing by cutting away the glass wall 9, connecting the two recesses to form a through decorative hole. Because the connection between the glass wall 9 and the bottle is thin, the area requiring grinding and finishing is smaller. However, after the molten glass accumulates in the middle of the glass wall 9, its thickness makes it more prone to flow. Therefore, after the mold block 2 separates, the molten glass in the middle of the glass wall 9 may sag and adhere to the bottle, making subsequent cutting of the glass wall 9 difficult.
[0031] In this embodiment, after the glass wall 9 is formed, the second telescopic rod 12 is activated. The second telescopic rod 12 pushes the top rod 11, and the pushing action of the top rod 11 drives a consumable rod 13 into the middle of the glass wall 9. The consumable rod 13 is a rigid structure. After being placed into the glass wall 9, the thick molten glass in the center of the glass wall 9 will adhere to the consumable rod 13 through adhesion, making it less likely to flow. This overcomes the problem that the molten glass accumulates due to the depression 8, causing it to flow downwards under gravity and stick to the glass bottle.
[0032] Because of the design of the consumable rod 13, the edge of the recess 8 is designed to be thinner to reduce the connection thickness between the glass wall 9 and the glass bottle. At the same time, the middle part of the recess 8 corresponds to the middle part of the subsequent glass wall 9. Its shape should enhance the adhesion between the molten glass and the consumable rod 13. Therefore, the middle part of the recess 8 is designed as a conical receiving pit 14 so that the middle part of the glass wall 9 can better fit the consumable rod 13.
[0033] The glass wall 9 and the consumable rod 13 will need to be cut off later. The glass wall 9 is made of glass, so it can be cleaned and recycled, improving resource utilization. The consumable rod 13 needs to have a certain degree of rigidity, so it can also be made of glass. When the glass wall 9 is cut off, it can be cleaned and recycled along with the glass wall 9.
[0034] When the consumable rod 13 is inserted into the glass wall 9, it will cause the glass wall 9 to deform. Although the glass wall 9 will be cut off later, if the deformation is too large, it will still affect the shape of the glass bottle. Therefore, one end of the consumable rod 13 is set as a flow guide 15. The flow guide 15 can reduce the deformation caused when the consumable rod 13 is inserted into the glass wall 9, so as not to affect the shape of the glass bottle.
[0035] Example 2 The difference from the above embodiment is that a filling groove 16 is provided on one side of the probe rod 7, and the filling groove 16 is connected to the hole 10. A snap-fit groove 17 is provided at the end of the consumable rod 13 away from the guide part 15. A metal part is detachably snapped into the snap-fit groove 17. The metal part includes a sheet 18, which is an iron sheet. An elastic snap-fit member 19 is bonded and fixed on the sheet 18. The elastic snap-fit member 19 can be a heat-resistant rubber block, an elastic metal sheet, etc. The elastic snap-fit member 19 is used to snap into the snap-fit groove 17.
[0036] One end of the push rod 11 near the consumable rod 13 is detachably connected to the consumable rod 13 via an electromagnet. The mold block 2 is equipped with a feeding component 20, which includes a box body 2001. The bottom of the box body 2001 has a release port 2002, and the box body 2001 has a storage cavity for stacking consumable rods 13. An electric release door 2003 is located at one end of the box body 2001 near the release port 2002, and an electric clamping assembly 2004 is also located at the same end. Both the electric release door 2003 and the electric clamping assembly 2004 consist of an electric push rod and a push block. The push block of the electric release door 2003 is used to close the release port 2002, while the push block of the electric clamping assembly 2004 is used to clamp the consumable rod 13. The electric clamping assembly 2004 is spaced apart from the electric release door 2003 by the height of one consumable rod 13. A buffer pad 21 is provided inside the hole 10, and the position of the buffer pad 21 corresponds to the filling groove 16.
[0037] The consumable rod 13 is used as a consumable and needs to be reassembled after each glass bottle is produced. Since the consumable rod 13 needs to be filled into the hole 10, the user needs to insert it into the mold block 2 for filling, which is inconvenient. Therefore, the filling process of the consumable rod 13 is improved by setting a filling groove 16 on one side of the probe 7. The user can insert the consumable rod 13 into the hole 10 through the filling groove 16, which optimizes the operation process. However, the filling efficiency is slow, and the operator needs to fill it after each glass bottle is produced, resulting in a decrease in output.
[0038] To further optimize the filling process, an automatic filling structure can be implemented. A feeder 20 is installed on the mold block 2. The feeder 20's housing 2001 can store several consumable rods 13, which are automatically released into the filling slot 16 through the release port 2002. The release of the consumable rods 13 is controlled by an electric clamping assembly 2004 and an electric release door 2003. When the electric release door 2003 is closed, the consumable rods 13 are stacked in the housing 2001. The electric clamping assembly 2004 clamps the second consumable rod 13 closest to the electric release door 2003. Thus, when the electric release door 2003 is opened, only one consumable rod 13 below the electric clamping assembly 2004 will fall down into the top rod 11, thereby controlling that only one consumable rod 13 is filled into the top rod 11 each time the feeder is used.
[0039] In addition to automatic feeding, an automatic connection structure is also required, meaning the consumable rod 13 needs to be detachably connected to the push rod 11; otherwise, when the mold block 2 moves, the consumable rod 13 may fall out of the hole 10. The consumable rod 13 is further improved by providing a locking groove 17 at the end of the consumable rod 13 away from the guide section 15, and a metal part is detachably locked within the locking groove 17. When the consumable rod 13 falls into the hole 10, the electromagnet at the end of the push rod 11 near the consumable rod 13 is energized, attracting the consumable rod 13 to the push rod 11 to constrain its position. After the consumable rod 13 is inserted into the glass wall 9, the electromagnet is de-energized, completing the detachment of the consumable rod 13. When the consumable rod 13 needs to be recycled and remelted, the metal part can be removed by forcefully pulling it out. The depth of the snap-fit groove 17 can be set to be much greater than the length of the elastic snap-fit part 19, so that the consumable rod 13 can have more hollow parts to reduce weight. The hollow parts need to be designed with vents to prevent cracking due to thermal expansion after contact with molten glass.
[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
