Description

Technical Field

[0001] The invention relates to the technical field of bottle making machines, and in particular to a glass tube bottle making machine with a preheating control function. Background Art

[0002] In the field of glass product production, especially in the glass bottle manufacturing industry, bottle making machines play a vital role. When processing glass tubes, traditional bottle making machines often preheat the glass tubes at the workstation before performing subsequent molding operations. This is because glass is a poor conductor of heat. If it is not preheated, various problems may occur in the glass bottles.

[0003] Among them, the structure of the bottle making machine and the function of each workstation are the same, and after the lamp head used for heating the glass tube on the workstation is debugged and qualified, the position is fixed. In this way, the standard of the produced bottles can be unified. However, it is precisely because the position of the heating lamp head and the structure of the bottle making machine are fixed that the traditional bottle making method is restricted. That is, the traditional bottle making method is to cut off the head end of the glass tube as waste. That is, after the glass tube runs to the second circle and the length specification meets the height requirement of the processing, the finished bottle is produced. If the finished bottle is produced at the head end of the glass tube in the first circle, the temperature is directly increased according to the adjusted heating lamp head. In this way, the heating and forming position of the glass tube is not uniform, and the softening of the glass material may increase, the produced glass bottles may be difficult to form, or the glass bottles may be easily unqualified.

[0004] Therefore, the traditional bottle making machine cannot make bottles at the head end of the glass tube, so about 60 mm of the glass tube at the head end of each glass tube will be wasted, resulting in a significant increase in production costs. Summary of the invention

[0005] The present invention provides a glass tube bottle making machine with a preheating control function, which solves the problem that the traditional bottle making machine in the related art cannot make bottles at the head end of the glass tube, so the head end part of each glass tube will be wasted, resulting in increased production costs.

[0014] A limit plate is arranged on the preheating seat, the limit plate is L-shaped, the corner of the limit plate is located above the flame spraying part, and the limit plate is used to limit the lifting height of the flame spraying part.

[0015] As a further technical solution, it also includes:

[0016] A lifting seat, the lifting direction of the flame spraying member and the lifting direction of the lifting seat are parallel to the rotation axis of the rotating working disk, the station is used to install the rotating glass tube, and also includes:

[0017] A follower plate is rotatably arranged on the lifting seat, and the rotation axis of the follower plate is parallel to the rotation axis of the glass tube. After the lifting seat supports the glass tube, the glass tube drives the follower plate to rotate.

[0018] As a further technical solution, it also includes:

[0019] A U-shaped limiting member is arranged on the lifting seat and is located above the follower plate, and the projection area of ​​the follower plate is located within the projection area of ​​the U-shaped limiting member.

[0020] As a further technical solution, it also includes:

[0021] A clamp is rotatably arranged on the workstation and is used for clamping the outer wall of the glass tube and driving the glass tube to rotate.

[0022] As a further technical solution, the follower plate has a through hole, the lifting seat has a groove, the through hole is connected to the groove, and further includes:

[0023] A centering piece is arranged in the groove and passes through the through hole, and the centering piece is used to limit the center position of the bottom of the glass tube.

[0024] As a further technical solution, the centering piece includes:

[0025] Two centering pendulums are swingably arranged on the inner wall of the groove, the two centering pendulums are symmetrically arranged, and one end of the centering pendulum has a centering portion, the centering portion is located in the glass tube, and after the centering pendulum swings, the centering portion abuts against or cancels the abutment against the inner wall of the glass tube.

[0026] As a further technical solution, the centering swing rod is in a broken line shape, and the centering member further includes:

[0029] The working principle and beneficial effects of the present invention are:

[0030] In order to realize the bottle making at the first end of the glass tube of the bottle making machine, the lifting seat of the second station of the bottle making machine is innovatively set up, that is, the positioning of the glass tube for the first loading and the positioning of the circulating bottle are treated differently, and the two are distinguished to different heights by lifting. The fixed length of the circulating bottle is the height of a bottle body. For example, the height of the bottle body should be 40mm. Then, after the lifting seat takes over the circulating bottle, the positioning push rod that pushes it to rise and fall is lowered by 40mm; for the glass tube loaded for the first time, the length of the first end of the material is 2-3mm, because the port here only makes the bottle mouth but not the bottle bottom, and it needs to be heated at the back station. Different treatment can realize personalized and precise control of the glass tube preheating process, and there is no need to cut off the head end, which improves the utilization rate of the tube, greatly saves costs, and improves economic benefits. It is of great significance.

[0031] Secondly, in order to adapt to the above adjustments and ensure the smooth progress of the bottle making process, the traditional preheating system under fixed position is changed, and the preheating seats of the 3rd, 4th and 5th stations of the bottle making machine are innovatively set. The preheating flame-jet parts installed thereon are changed to be highly controllable, that is, the preheating function is adjusted accordingly. For the glass tubes loaded for the first time, the flame-jet parts on the preheating seat should be raised by 2-3mm, so that the head end of the tube mouth can be baked when passing through the 3rd, 4th and 5th stations, and then restored to their original position after baking. In this way, the glass tube can be produced qualified only when the subsequent bottle is formed; for the cycle production of bottles, the flame-jet parts will not be moved after arriving at the 3rd, 4th and 5th stations, and the glass tubes that have been fixed in length will be baked and heated, and then run to the subsequent stations for bottle bottom separation, so as to ensure the uniformity of product quality, so that the bottle making machine can quickly adapt to different production tasks and achieve the goal of not generating waste at the head end of each glass tube of the bottle making machine and directly producing finished bottles.

DETAILED DESCRIPTION

[0042] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0044] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0046] Reference Figure 1 to Figure 8, which is the first embodiment of the present invention, proposes a glass tube bottle machine with a preheating control function, comprising: a rotating working disk 1, the rotating working disk 1 has a plurality of workstations 101, the plurality of workstations 101 are arranged along the circumference of the rotating working disk 1, and the workstations 101 are used to install glass tubes 2; a plurality of preheating seats 3 and lifting seats 7, after the rotating working disk 1 rotates, the workstations 101 drive the glass tube 2 to pass through the lifting seats 7 first, and then pass through each of the preheating seats 3 in turn, the lifting seats 7 are located below the workstations 101, and the lifting seats 7 are used to support and determine the height position of the glass tube 2 after being lifted; a flame spraying part 4, the flame spraying part 4 is lifted and arranged on the preheating seat 3, and the flame spraying part 4 is used to heat the glass tube 2 at different heights after being lifted.

[0047] In this embodiment, the glass tube is automatically fixed in length during the production process. When the bottle making machine is working, the glass tube 2 is inserted into the station 101 of the rotating working disk 1. The tube insertion action is completed by the tube insertion machine. At the same time, the tube insertion machine can transmit a signal to the lifting seat 7 of the second station, and then the positioning push rod in the form of a cylinder pushes the lifting seat 7 to rise and fall after receiving the signal, so that the tube mouth reaches the height of the rolled bottle mouth; after the height of different glass tubes is determined according to the signal, the automatic lifting and heating system at the subsequent third, fourth, and fifth stations is used, that is, driven by the rotating working disk 1, the glass tube 2 on the station 101 passes through a plurality of preheating seats 3 in sequence, and the preheating seats 3 are The liftable flame spraying part 4 is only executed when the first round of glass tubes are made into bottles. The lifting and heating system is no longer executed for other glass tubes after the first round. The design of the multi-station 101 and the liftable flame spraying part 4 enables the bottle making machine to flexibly adjust the preheating time and heating intensity according to actual production needs to achieve the best preheating effect, and there is no need to cut off the head end, thereby ensuring process consistency and ensuring that in the subsequent preheating process, each incoming glass tube 2 can enter the preheating process at the required height position, thereby improving the utilization rate of the tubes, greatly saving costs, and improving economic benefits. It is of great significance and also ensures the stability of product quality and the continuity and repeatability of the process.

[0048] Specifically, for the glass tube that is loaded for the first time, the length of the head end can be 2-3mm, because the port here only makes the bottle mouth but not the bottle bottom, it needs to be heated at the subsequent station, and then when passing through the preheating seat 3, the flame-spraying part on the preheating seat should be raised by 2-3mm, so that the head end of the tube can be baked when passing through the 3rd, 4th and 5th stations, and return to its original position after the baking is completed. After that, the No. 6 station will use a fixed lamp holder to spray fire and heat it up, and then the purpose of bottle mouth molding can be achieved through subsequent processing, which meets the production standards.

[0049] Furthermore, a plurality of preheating seats 3 are arranged along the circumference of the rotating working disk 1, and the flame spraying part 4 has a connecting portion 401, and also includes: a driving shaft 5, which is rotatably arranged on the preheating seat 3, located on one side of the flame spraying part 4, and is threadedly connected to the connecting portion 401. After the driving shaft 5 rotates, it drives the flame spraying part 4 to rise and fall.

[0050] In the present embodiment, a threaded drive is adopted for the lifting of the flamethrower 4. Specifically, a rotating drive shaft 5 is driven by a motor on the fixed preheating seat 3, which is threadedly connected to a plate-type connecting portion 401 welded on the flamethrower 4 to drive the flamethrower 4 to lift and lower. The flamethrower 4 uses a pipeline flame-spraying method connected to the combustible gas, which facilitates adjusting the combustible gas flow rate through a valve on the pipeline, thereby controlling the amount of flame spraying, thereby controlling the heating temperature.

[0051] Furthermore, it also includes: a limit plate 6, which is arranged on the preheating seat 3, the limit plate 6 is L-shaped, and the corner of the limit plate 6 is located above the flame spraying part 4, and the limit plate 6 is used to limit the lifting height of the flame spraying part 4.

[0052] In this embodiment, in order to determine the lifting height of the flamethrower 4 according to the actual production scenario, an L-shaped limit plate 6 made of steel is welded on the preheating seat 3. While realizing the function, the structure is simplified and the cost is greatly saved. It is ensured that the corner of the limit plate 6 is located above the flamethrower 4, and then when the height is raised to adapt to the processing position of different products, the highest position is limited to prevent the flamethrower 4 from rising all the time, resulting in the disconnection of the connecting part 401 and the drive shaft 5, and the subsequent steps cannot be carried out.

[0053] Furthermore, the lifting direction of the flame-spraying member 4 and the lifting direction of the lifting seat 7 are both parallel to the rotation axis of the rotating working disk 1. The workstation 101 is used to install the rotating glass tube 2, and also includes: a follower disk 8, which is rotatably arranged on the lifting seat 7, and the rotation axis of the follower disk 8 is parallel to the rotation axis of the glass tube 2. After the lifting seat 7 supports the glass tube 2, the glass tube 2 drives the follower disk 8 to rotate.

[0054] In this embodiment, since the lifting direction of the flame spraying member 4 and the lifting direction of the lifting seat 7 are both parallel to the rotation axis of the rotating working disk 1, the two realize precise coordinated work in the height direction. When the flame spraying member 4 is lifted and lowered according to the process requirements to heat the glass tube 2 at different height positions, the height position of the glass tube 2 determined by the lifting seat 7 can accurately correspond to the heating position of the flame spraying member 4, avoiding the heating deviation caused by the height instability of the glass tube 2, further improving the accuracy and uniformity of heating, helping to optimize the preheating effect of the glass tube 2 and improve product quality.

[0055] In the operation of the bottle making machine, the glass tube 2 is not only driven to switch between each station 101, but also needs to be rotated by other components to evenly bear the heating temperature of the flame spraying part 4. Therefore, a follower plate 8 parallel to the axial direction of the glass tube 2 is further installed on the top of the lifting seat 7 through a bearing. When the lifting seat 7 lifts and supports the glass tube 2 to a specified height, the follower plate 8 rotates with the glass tube 2, reducing the relative sliding friction between the glass tube 2 and the lifting seat 7, greatly reducing the damage to the surface of the glass tube 2 caused by friction and the resistance to the operation of the equipment. This helps to maintain the smoothness of the surface of the glass tube 2, reduce the generation of impurities, and reduce the wear and energy consumption of the equipment caused by friction, extend the service life of the equipment, and improve the stability and smoothness of the equipment operation.

[0056] Furthermore, it also includes: a U-shaped limiting member 9, which is arranged on the lifting seat 7 and located above the follower plate 8, and the projection area of ​​the follower plate 8 is located within the projection area of ​​the U-shaped limiting member 9.

[0057] The welding and fixing of the U-shaped limiter 9 facilitates providing a protective limiter for the glass tube 2 in the process of the lifting seat 7 supporting the glass tube 2 to a specified height, constraining the movement of the glass tube 2, preventing the glass tube 2 from tilting or falling in the vertical direction, and avoiding the position where the glass tube 2 is separated from the lifting seat 7, and can be separated directly under the drive of the rotating working disk 1; and in order to ensure that the relative position of the glass tube 2 and each component is accurate during the entire processing process, which is beneficial to the normal operation of the equipment and the smooth progress of the production process, the projection area of ​​the follower disk 8 is required to be within the projection area of ​​the U-shaped limiter 9 to ensure that the follower disk 8 is within the U-shaped limiter 9.

[0058] The U-shaped stopper 9 is arranged without occupying too much space, and can ingeniously realize the effective limit of the glass tube 2. Its compact structure, coordinated with the layout of the lifting seat 7, the follower plate 8 and other components, helps to optimize the overall spatial structure of the equipment, making the equipment more compact and reasonable, improving the space utilization rate of the production site, and facilitating the installation, maintenance and operation of the equipment.

[0059] Furthermore, it also includes: a clamp 10, which is rotatably arranged on the work station 101, and is used to clamp the outer wall of the glass tube 2 and drive the glass tube 2 to rotate.

[0060] In this embodiment, the bottle making machine uses the clamp 10 at the station 101 to determine the position of the glass tube 2 and drives it to rotate relative to the station 101 to complete the corresponding processing steps. The clamp 10 is usually made of soft material to avoid damaging the glass tube 2, and has a certain gap with the incoming glass tube 2 to adjust different clamping positions. Therefore, after the incoming material is stably supported by the lifting seat 7, the clamp 10 stably clamps the glass tube 2.

[0061] Furthermore, the follower plate 8 has a through hole 801, the lifting seat 7 has a groove 701, the through hole 801 is connected to the groove 701, and also includes: a centering piece 11, the centering piece 11 is arranged in the groove 701 and passes through the through hole 801, and the centering piece 11 is used to limit the bottom center position of the glass tube 2.

[0062] In this embodiment,

[0063] During the clamping process of the clamp 10, the glass tube 2 may be clamped crooked due to the lack of components for accurately centering the glass tube 2. When it is subsequently transferred to a different processing position, the processing and heating effect is further affected. Therefore, a centering piece 11 is installed at the lifting seat 7 to accurately center the glass tube 2 before it is fed into the material or preheated to ensure product quality.

[0064] In the initial stage, the glass tube 2 is accurately placed on the follower plate 8. At this time, the centering piece 11 located in the groove 701 of the lifting seat 7 extends upward through the through hole 801 opened in the follower plate 8 to accurately limit the bottom center position of the glass tube 2. When the glass tube 2 starts to rotate under the action of the clamp 10, it drives the follower plate 8 to rotate synchronously. The centering piece 11 and the clamp 10 work together to ensure that the glass tube 2 remains in a stable state during the rotation process without any displacement or shaking. Under such stable conditions, the glass tube 2 passes through each preheating seat 3 in turn, is heated by the flame-spraying piece 4, completes the preheating process, and then enters the subsequent bottle making process.

[0065] Furthermore, the centering piece 11 includes: two centering pendulum rods 1101, the two centering pendulum rods 1101 are swingably set on the inner wall of the groove 701, the two centering pendulum rods 1101 are symmetrically set, and one end of the centering pendulum rod 1101 has a centering portion 1102, the centering portion 1102 is located in the glass tube 2, after the centering pendulum rod 1101 swings, the centering portion 1102 abuts against or cancels the abutment against the inner wall of the glass tube 2.

[0066] In this embodiment, the specific centering member 11 includes two centering pendulum rods 1101. When the glass tube 2 is placed on the follower disk 8, the centering pendulum rod 1101 is initially in a natural state. Subsequently, the centering pendulum rod 1101 starts to swing through an external driving mechanism (such as air circuit control, cylinder, motor, etc.) or other linkage devices, and the centering portion 1102 at one end of the centering pendulum rod 1101 gradually approaches the inner wall of the glass tube 2 until it abuts against the inner wall of the glass tube 2, thereby performing a centering operation on the glass tube 2 from the inside.

[0067] At this time, the centering parts 1102 of the two symmetrically arranged centering rocker arms 1101 work together to accurately determine the center position of the glass tube 2 so that it can be correctly and accurately clamped by the clamp 10 later. When the glass tube 2 needs to be transferred to the next workstation 101, the centering rocker arm 1101 is driven to swing in the opposite direction, and the centering part 1102 cancels the contact with the inner wall of the glass tube 2. At the same time, the lifting seat 7 is lowered to make the centering piece 11 extend out of the glass tube 2 as a whole. The glass tube 2 can be smoothly transferred by the rotating work disk 1. The whole process realizes the effective control and flexible adjustment of the center position of the glass tube 2, ensuring the accuracy and stability of the processing process.

[0068] Furthermore, the centering rocker 1101 is in a broken line shape, and the centering member 11 also includes: a driving platform 1103, which is raised and lowered in the groove 701, and the driving platform 1103 has two guiding slopes 1104, and the two guiding slopes 1104 are symmetrically arranged, and the other end of the centering rocker 1101 abuts against the guiding slope 1104. After the driving platform 1103 is raised and lowered, it drives the two centering rockers 1101 to swing.

[0069] In this embodiment, the structure of driving the centering pendulum 1101 adopts the form of a driving platform 1103 that is lifted and lowered in the groove 701. Its lifting and lowering relies on simple air path control to ensure that the driving platform 1103 has a short lifting path. The two symmetrically arranged guide slopes 1104 of the driving platform 1103 provide a limiting guide function for the other end of the centering pendulum 1101. As the driving platform 1103 rises, its two symmetrically arranged guide slopes 1104 contact and interact with the other end of the centering pendulum 1101. Due to the inclination angle of the guide slopes 1104, the centering pendulum 1101 is thrust by the slopes and begins to swing. The centering pendulum 1101 swings with its connection point with the inner wall of the groove 701 as the axis, so that the centering portion 1102 located in the glass tube 2 gradually approaches the inner wall of the glass tube 2. Finally, the centering portion 1102 closely abuts against the inner wall of the glass tube 2, and the glass tube 2 is centered and positioned from the inside, ensuring the stability of the glass tube 2 during rotation and processing.

[0070] The centering rocker 1101 is designed to be in a broken line shape, so as to pass through the through hole 801 of the follower plate 8 and avoid the position of the follower plate 8 .

[0071] Furthermore, the guiding inclined surface 1104 has a guiding groove 1105 , and the other end of the centering rocker 1101 has a guiding portion 1106 , and the guiding portion 1106 is slidably disposed in the guiding groove 1105 .

[0072] In this embodiment, in order to ensure that the guiding slope 1104 can always act on the other end of the centering pendulum 1101 so that it can follow the driving platform 1103 to move, a guiding groove 1105 is opened on the surface of the guiding slope 1104, and a guiding part 1106 adapted to the bottom of the other end of the centering pendulum 1101 is welded, and the two are connected by snap-connection, and ensure that the guiding part 1106 can slide in the guiding groove 1105, such as a T-shaped or special-shaped design, so that after the driving platform 1103 is raised or lowered, the centering pendulum 1101 can be stably pushed to complete the centering operation.
