Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of glass container manufacturing, and particularly relates to a glass container and a glass container manufacturing process. BACKGROUND

[0002] Glass containers are common utensils in daily life and are widely used in beverage containers, food packaging, laboratory utensils and other fields. The traditional glass container production process mainly adopts blowing or pressing forming methods to make the glass melt material into the required shape in the mold. However, the existing technology still has many limitations in producing glass containers with special surface structures;

[0003] In the glass container forming process, the traditional blowing forming method mainly relies on gas pressure to make the glass melt material adhere to the inner wall of the mold. This method is good for simple container shapes, but when fine surface pits or complex textures are needed, the glass melt material often cannot fully fill the fine structure of the mold, resulting in incomplete forming or uneven thickness. Especially in the manufacture of glass containers with multiple pits, the flowability of the glass melt material is limited during the static blowing process, making it difficult to perfectly wrap the protruding structure inside the mold, resulting in blurred pit profiles and inconsistent depths on the surface of the final product. SUMMARY

[0004] Therefore, the technical problem to be solved by the present application is to provide a glass container and a glass container manufacturing process that can make the melt material uniformly adhere to the mold and form clear pits during the blowing forming process of the glass container, thereby improving the forming quality.

[0005] A glass container manufacturing device comprises a fixed ring, a rotating ring rotatably connected to the fixed ring, a moving seat fixedly connected to the rotating ring, two semicircular blocks connected to the moving seat, a plurality of cylindrical protrusions fixedly connected to each semicircular block, the two semicircular blocks capable of being combined into a complete cylinder, and an incomplete arc groove formed in each semicircular block.

[0006] The device further comprises a base, a rotating shaft connected to the base, a support plate fixedly connected to the rotating shaft, and a bottom plate fixedly connected to the lower side of the base, wherein the support plate can be inserted between the two semicircular blocks.

[0007] The device further comprises two insertion rods slidably connected to the rotating shaft, two insertion holes formed in the moving seat, and the rotating shaft rotatably connected to the base.

[0008] The device further comprises a driving plate slidably connected to the base, a driving ring fixedly connected to the driving plate, and the two insertion rods slidably connected to the driving ring.

[0009] The glass container manufacturing device is used for a manufacturing process of the glass container, and the process comprises the following steps.

[0010] Step one: combine two half-circular blocks with multiple cylindrical protrusions on the inner wall into a complete cylindrical mold, and position the support plate at the bottom of the mold;

[0011] Step two: fill the glass melt into the forming space formed by the two half-circular blocks and the support plate;

[0012] Step three: insert the blowing pipe into the channel formed by the incomplete arc groove of the half-circular blocks, and blow gas into the glass melt;

[0013] Step four: drive the rotating ring to rotate at a uniform speed, and the glass melt is continuously and uniformly pressed towards the inner wall of the mold under the action of centrifugal force, ensuring that it fully fills the mold groove and tightly wraps the cylindrical protrusions, thereby obtaining a clear and consistent pit texture;

[0014] Step five: after the glass container is cooled and shaped, operate the electric push rod to smoothly separate the two half-circular blocks along the horizontal rod;

[0015] Step six: slide the two L-shaped rods, remove the glass container after cooling, and complete the processing. BRIEF DESCRIPTION OF DRAWINGS

[0027] The utility model provides a glass container manufacturing equipment, including fixed ring 201, rotationally connected with rotating ring 202 on fixed ring 201, and fixedly connected with moving seat 203 on rotating ring 202, and two half circular arc blocks 101 are connected on moving seat 203, and a plurality of cylindrical bosses 103 are fixedly connected in each half circular arc block 101, and two half circular arc blocks 101 can be spliced into a complete cylinder, and not complete arc groove 105 is set up on each half circular arc block 101, and first motor is fixedly connected on fixed ring 201, and gear is fixedly connected on the output shaft of first motor, and gear ring is fixedly connected on rotating ring 202, and gear is engaged with gear ring, and one mould groove is arranged in each half circular arc block 101, and a plurality of cylindrical bosses 103 are fixedly connected in a plurality of mould grooves.

[0028] Before carrying out forming operation, the glass melt to be blown is placed in the space between two half circular arc blocks 101, then the gas pipe that can be blown is inserted into the circular arc groove formed by two not complete arc grooves 105, then the gas pipe is started to blow gas into the glass melt, so that the glass melt is expanded and shaped according to the mould groove between two half circular arc blocks 101, thereby forming the glass container shape, and in the process of forming the specified shape, the glass melt will be attached to a plurality of cylindrical bosses 103, thereby forming a glass container with a plurality of pits on the surface, thereby achieving the effect of manufacturing a glass container with pits.

[0029] After the glass material is contacted with the space between two half circular arc blocks 101 by blowing gas, thereby generating certain adhesion, the rotating ring 202 can be rotated on the fixed ring 201, thereby driving the moving seat 203 to rotate synchronously, in the process, two half circular arc blocks 101 will rotate synchronously with the moving seat 203, thereby making the glass container rotate synchronously with two half circular arc blocks 101, in the rotating process, the glass melt will be thrown outward due to the centrifugal force, thereby making the glass melt more efficiently and uniformly attached to the surface of a plurality of cylindrical bosses 103, thereby ensuring the forming effect of the glass container, in the process, two not complete arc grooves 105 will rotate continuously, and the gas pipe will not move, thereby ensuring the normal operation of the gas pipe gas inlet operation, thereby cooperating with the rotation of two half circular arc blocks 101 to make the glass melt more fully attached to the mould groove inside two half circular arc blocks 101, and uniformly attached to the surface of a plurality of cylindrical bosses 103, thereby forming a glass container with pits.

[0030] When the rotating ring 202 drives the semicircular block 101 to rotate, the glass melt is continuously pressed outward under the action of centrifugal force. This dynamic pressure supplements the filling force brought by the gas pressure in the static blowing process, so that the glass melt can be more tightly and uniformly filled into every corner of the mold groove, especially in complex or more subtle structures. This effectively reduces defects such as local thinning or insufficient filling caused by poor flow of glass melt. Under the action of pure blowing, the melt may not perfectly wrap the bumps to form clear pits. The centrifugal force generated by rotation provides the glass melt with a normal pressure towards the side of the bumps, prompting the melt to more fully wrap each cylindrical bump 103, thereby forming pits on the surface of the container with clearer contours and more consistent depth, improving the forming quality of the surface texture.

[0031] The pits can create gaps between the cup walls, which can prevent the cups from being tightly sucked together due to negative pressure when multiple cups are stacked for storage, making the stack more stable and easier to access. At the same time, the pits provide a natural resting place for the fingers, forming an excellent anti-slip effect and making the grip more stable, effectively preventing slipping.

[0032] The base 401 is also provided, and the rotating shaft 301 is connected to the base 401. The support plate 302 is fixedly connected to the rotating shaft 301. The bottom plate 402 is fixedly connected to the lower side of the base 401. The support plate 302 can be inserted between the two semicircular blocks 101.

[0033] After the glass melt is placed between the two semicircular blocks 101, the support plate 302 will support the glass melt, allowing it to be in the space formed between the support plate 302 and the two semicircular blocks 101. Then the glass melt is blown and rotated to successfully complete the subsequent glass container forming operation.

[0034] The surface of the support plate 302 can be made of a material that is not easily adhered to glass, such as a special ceramic coating or treated graphite, which is not easily adhered to glass and has a certain wear resistance. When the glass melt is blown and expanded to adhere between the two semicircular blocks 101, and then the two semicircular blocks 101 are rotated to drive the glass melt to rotate, the support plate 302 will not rotate, thereby continuously rubbing the bottom surface of the glass container against the surface of the support plate 302, naturally abrading and smoothing the bottom surface of the glass container, and effectively eliminating the burrs or unevenness that may occur due to improper demolding or bottom treatment in traditional processes, directly obtaining a smooth bottom surface.

[0035] The bottom plate 402 can be in contact with the ground, thereby supporting the base 401 and stably supporting the support plate 302.

[0036] It also includes two plug rods 303 that are slidably connected to the rotating shaft 301. The movable seat 203 is provided with two plug holes 204. The two plug rods 303 can be inserted into the two plug holes 204 respectively. The rotating shaft 301 is rotatably connected to the base 401.

[0037] An electromagnetic block is provided on the base 401. Under normal circumstances, the electromagnetic block is used to attract and fix the rotating shaft 301 to prevent the rotating shaft 301 from rotating. When the glass container to be formed cannot withstand the abrasion and smoothing operation intensity when it is not completely cooled due to its own material or thickness characteristics, the attraction force of the electromagnetic block can be removed. Then, the two plug rods 303 are slid upward and inserted into the two plug holes 204. Subsequently, when the rotating ring 202 rotates, the rotating ring 202 will drive the moving seat 203 to rotate. The rotating moving seat 203 will drive the rotating shaft 301 to rotate through the cooperation of the two plug holes 204 and the two plug rods 303, so that the support plate 302 rotates synchronously with the glass container. This maintains the support effect while eliminating the grinding effect on the bottom surface of the glass container, so as to adapt to different production needs.

[0038] It can quickly switch between two processing modes: bottom surface polishing and no polishing. This allows a single machine to efficiently produce a variety of glass containers, from thick-walled cups that require a mirror-like bottom to thin-walled art cups that cannot withstand polishing, without the need to change molds or adjust the entire production line. This greatly improves equipment utilization and production scheduling efficiency. It is suitable for flexible production lines with multiple varieties and small batches, or for producing high-end glass products with complex shapes and uneven thicknesses. It can select the most suitable bottom surface treatment solution according to the specific characteristics of each batch of products.

[0039] It also includes a drive plate 501 that is slidably connected to the base 401, a drive ring 502 that is fixedly connected to the drive plate 501, two plug rods 303 that are slidably connected to the drive ring 502, the cross-section of the drive ring 502 is T-shaped, and an electric push rod A that can push the drive plate 501 to slide is fixedly connected to the base 401.

[0040] The drive ring 502 can be moved by sliding the drive plate 501 up and down. The movement of the drive ring 502 will naturally cause the two plug rods 303 to slide, so that the two plug rods 303 can be inserted into the two plug holes 204. This ensures that the subsequent support plate 302 can rotate synchronously with the glass container and smoothly carry out the subsequent molding operation.

[0041] Further comprising two support rods 606, both of which are fixedly connected to the moving seat 203, each of which is fixedly connected with a connecting plate 603, both sides of each connecting plate 603 are fixedly connected with two side plates 601, two transverse rods 602 are fixedly connected between the two side plates 601 located on the same connecting plate 603, two sliding strips 104 are fixedly connected on each semicircular block 101, each sliding strip 104 is sliding between two transverse rods 602 in the vertical direction, the front side plate 601 is fixedly connected with an electric push rod B capable of pushing the front semicircular block 101 to slide, and the rear side plate 601 is fixedly connected with an electric push rod C capable of pushing the rear semicircular block 101 to slide.

[0042] When the rotation is completed and cooled by a period of standing, thereby removing the adhesion effect of the glass and the inner wall of the two semicircular blocks 101, the two semicircular blocks 101 can be operated to slide away from each other on the plurality of transverse rods 602, thereby taking out the glass container and completing the processing operation. When the two semicircular blocks 101 move, the air pipe will not move in the horizontal direction, but only move upward in the vertical direction, thereby avoiding interference during subsequent movement of the incomplete arc groove 105. Subsequently, the air pipe is fixed, thereby limiting the glass container when the two semicircular blocks 101 move, peeling the glass container from the two semicircular blocks 101 while keeping the glass container on the support plate 302 at all times, avoiding accidental dropping of the glass container, causing damage. That is, the air pipe forms a natural constraint on the mouth of the glass container, helping to peel the container from the inner wall of the mold while effectively preventing the container from moving with the mold or toppling over. The peeled glass container finally falls stably on the support plate 302 which is always stationary, thereby completely avoiding the risk of accidental dropping and breaking of the container during demolding.

[0043] Further comprising a top ring 701, two L-shaped rods 704 are connected to the top ring 701, and the two L-shaped rods 704 can slide along the top ring 701. Each L-shaped rod 704 is detachably connected with a blower capable of blowing cold air through a bolt.

[0044] After the two semicircular arc blocks 101 are moved away and the glass container is exposed, the two air blowers are started to blow cold air on the surface of the glass container, so that the glass container is quickly cooled and formed, ensuring the forming effect of the glass container. At the same time, the two L-shaped rods 704 can be operated to slide along the top ring 701, so that cold air is blown from different angles to the surface of the glass container, ensuring comprehensive cooling effect, facilitating cooling at different angles for the position of the pit, so as to ensure that the pit position can also be fully cooled and formed during the cooling and forming process, further ensuring the overall forming effect of the pit glass container. For the inwardly recessed structure of the pit, the traditional environmental cooling airflow cannot effectively enter, and the present device can directly blow air into the pit from multiple angles such as the oblique side, effectively reducing the internal stress caused by uneven cooling inside and outside, avoiding the occurrence of micro-cracks or contour deformation at the edge of the pit, so as to ensure that the geometry of the pit is clear and regular.

[0045] The moving blocks 702 are also included, and two moving blocks 702 are slidingly connected to the top ring 701. Each moving block 702 is fixedly connected with a contact arc block 703, and each contact arc block 703 is fixedly connected with an L-shaped rod 704 through a diagonal rod.

[0046] After the two semicircular arc blocks 101 are moved away and the glass container is exposed, the two air blowers are started to blow cold air on the surface of the glass container, so that the glass container is quickly cooled and formed, ensuring the forming effect of the glass container. At the same time, the two L-shaped rods 704 can be operated to slide along the top ring 701, so that cold air is blown from different angles to the surface of the glass container, ensuring comprehensive cooling effect, facilitating cooling at different angles for the position of the pit, so as to ensure that the pit position can also be fully cooled and formed during the cooling and forming process, further ensuring the overall forming effect of the pit glass container. For the inwardly recessed structure of the pit, the traditional environmental cooling airflow cannot effectively enter, and the present device can directly blow air into the pit from multiple angles such as the oblique side, effectively reducing the internal stress caused by uneven cooling inside and outside, avoiding the occurrence of micro-cracks or contour deformation at the edge of the pit, so as to ensure that the geometry of the pit is clear and regular.

[0047] The air blower is no longer fixed at one point, but moves with the moving block 702 on the top ring 701, and the blowing angle and coverage range continuously change. This dynamic sweeping ensures that cold air uniformly acts on the entire outer surface of the glass container, avoiding local temperature difference and internal stress concentration that may be caused by fixed-point cooling, which is crucial for preventing glass container deformation or micro-cracks. The pit and other inwardly recessed structures are difficult to cool, and the linkage mechanism enables the air blower to blow air from multiple angles into the pit, ensuring that the inner and outer walls of the pit are cooled synchronously and uniformly, so as to ensure that the geometry of the pit is clear and regular, effectively improving the forming quality of containers with special surface texture.

[0048] The top ring 701 is provided with an annular rubber, which can increase the sliding friction of the moving block 702, so that the moving block 702 can be stably placed on the top ring 701 without other external forces, waiting for subsequent driving operation.

[0049] Each of the connecting plates 603 is fixed with two inclined plates 604, and the two inclined plates 604 on each connecting plate 603 are distributed in a V shape. The front end of each V-shaped area is provided with a rectangular groove 605, and a plurality of air holes are formed on each connecting plate 603.

[0050] The V-shaped area is opposite the area where the plurality of pits are located. When the air blower is used to blow, the cold air blown by the air blower can be gathered by the V-shaped area, and then the rectangular groove 605 is used to blow the pit area in a targeted manner, so as to strengthen the cooling effect of the pit area, and further facilitate the stable formation of the pit area, and improve the efficient and stable forming function;

[0051] The two inclined plates 604 distributed in a V shape on each connecting plate 603 form an effective air collecting area. The V-shaped structure is opposite the pit area on the glass container, and the rectangular groove 605 at the front end acts as an air nozzle. When the air blower is started, the cold air that may be diffused is effectively gathered by the V-shaped area, and is accelerated to shoot out through the narrow outlet of the rectangular groove 605, forming a concentrated and higher intensity cooling airflow. This reinforced airflow is precisely directed to the pit, which is a key part with relatively poor heat dissipation conditions and difficult cooling, achieving targeted air cooling reinforcement, effectively promoting the synchronous and uniform cooling of the inner and outer walls of the pit. This is crucial for preventing the pit from deforming or generating internal stress due to uneven cooling, and directly improves the forming precision and structural integrity of the container with special surface texture;

[0052] The air holes on the connecting plate 603 can reduce the shielding of the connecting plate 603 to the cold air, further avoiding the formation of a dead zone at the position of the connecting plate 603 during the cooling process, and ensuring the uniformity of the cooling operation;

[0053] The connecting plate 603 itself has a certain volume. If it is a solid structure, it will block and disturb the cooling airflow in the rear area, and it is easy to form a slow cooling dead zone at the corresponding position on the surface of the glass container, leading to uneven cooling rate of each part of the product, and then causing warping or stress concentration. By opening a plurality of air holes on the connecting plate 603, part of the cooling air can penetrate the connecting plate itself. This design significantly reduces the shielding area of the connecting plate to the airflow, ensures that the airflow can more uniformly cover the entire surface of the glass container, thereby effectively eliminating the potential cooling dead zone and ensuring the uniformity of the cooling process, providing a key process guarantee for obtaining a glass container with high dimensional stability and low internal stress.

[0054] The glass container manufacturing device is used for a manufacturing process of a glass container, and the process comprises the following steps:

[0055] Step one: combine two half-circular blocks 101 with multiple cylindrical protrusions 103 fixed on the inner wall into a complete cylindrical mold, and position the support plate 302 at the bottom of the mold;

[0056] Step two: fill the glass melt into the forming space formed by the two half-circular blocks 101 and the support plate 302;

[0057] Step three: insert the blowing pipe into the channel formed by the incomplete arc grooves 105 of the half-circular blocks 101, and blow gas into the glass melt;

[0058] Step four: drive the rotating ring 202 to rotate at a constant speed, and the glass melt is continuously and uniformly pressed to the inner wall of the mold under the action of centrifugal force, so as to ensure that the glass melt fully fills the mold groove and tightly wraps the cylindrical protrusions 103, thereby obtaining a clear and consistent recess texture;

[0059] Step five: after the glass container is preliminarily cooled and shaped, operate the electric push rod to smoothly separate the two half-circular blocks 101 along the transverse rod 602;

[0060] Step six: slide the two L-shaped rods 704, take down the glass container after cooling, and complete the processing.

[0061] The glass container manufactured by the glass container manufacturing process has a plurality of recesses on the surface.
