Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, specifically to an automatic bottle conveying machine. Background Technology

[0002] In the glass bottle manufacturing industry, the formed glass bottles need to be transported to an annealing furnace for annealing treatment to eliminate internal stress and ensure product quality. The traditional method is manual bottle feeding, in which bottle carriers shuttle back and forth between the bottle-making machine and the annealing furnace. This method has obvious drawbacks: on the one hand, the bottle carriers' labor intensity is extremely high, requiring frequent handling of glass bottles, which can easily lead to physical fatigue and injury over long periods of time; on the other hand, in order to maintain production efficiency, a large number of bottle carriers need to be employed, resulting in high labor costs and severely limiting the economic benefits and development scale of enterprises.

[0003] With technological advancements, the technology of conveyor belts for transporting glass bottles has been increasingly applied in production. However, glass bottles removed from the bottle-making machine are at high temperatures. If placed directly on the conveyor belt, the heat is concentrated at the bottom of the bottle, and the bottom of the bottle is in direct contact with the conveyor belt, causing rapid heat conduction and a sudden drop in temperature at the bottom. Meanwhile, the temperature of other parts of the bottle drops more slowly. This uneven temperature change generates significant thermal stress inside the glass bottle, easily leading to cracks or even breakage. Furthermore, as the bottles move on the conveyor belt, friction and collisions between the bottles and with the belt itself can cause scratches and damage to the fragile surface of the glass at high temperatures, affecting the product's appearance and performance.

[0004] Existing technology CN209537308U discloses a cooling device for glass bottle manufacturing. It uses gas storage bags on both sides of a conveyor belt. When a glass bottle is conveyed between the gas storage bags, the bags discharge gas to cool the lower end and bottom of the bottle, effectively reducing the temperature of the bottom. However, this technology still has several drawbacks: 1. It only cools the glass bottle during the conveying process. Due to the limitation of the conveying distance, it may not achieve a good cooling effect. To achieve the ideal cooling effect, the conveying distance of the cooling area needs to be increased, which undoubtedly extends the production line length, increases factory space requirements and equipment investment costs, and also reduces production efficiency; 2. When cooling glass bottles with high temperatures, the high temperature may affect the structure and performance of the gas storage bags, posing an explosion risk and threatening production safety. Utility Model Content

[0005] The present invention aims to provide an automatic bottle conveying machine to automatically transport glass bottles and ensure the cooling effect of the glass bottles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic bottle conveyor includes a conveyor belt with a secondary cooling mechanism and a primary cooling mechanism at the feeding end of the conveyor belt. The primary cooling mechanism includes a temporary storage platform with a first cooling air duct around its top. The inner side of the first cooling air duct has a plurality of first air holes evenly distributed. The temporary storage platform has a plurality of placement trays evenly distributed, each with bottle bottom cooling air holes. The temporary storage platform has a cooling air channel that communicates with the bottle bottom cooling air holes. The first cooling air duct is connected to the cooling air channel and is connected to a cooling air source.

[0008] Preferably, as an improvement, the conveyor belt includes a supporting square tube with supporting feet at the bottom. A drive wheel is rotatably mounted at one end of the supporting square tube, and a driven wheel is rotatably mounted at the other end. A conveyor belt is tensioned between the drive wheel and the driven wheel. The top of the supporting square tube is supported below the top surface of the conveyor belt. The secondary cooling mechanism includes a second cooling duct installed inside the supporting square tube. The second cooling duct is connected to a cooling air source. Several second air holes are evenly distributed on the top of the second cooling duct. The top plate of the supporting square tube consists of a perforated top plate and a non-perforated top plate. The perforated top plate is located above the second cooling duct and is positioned near the feeding end of the conveyor belt.

[0009] Preferably, as an improvement, the non-perforated top plate is covered with an insulation cover, which is placed on the conveyor belt, and the inner wall of the insulation cover is provided with a high-temperature resistant insulation layer.

[0010] Preferably, as an improvement, the insulation cover includes three sub-insulation covers, which are detachably connected to the supporting square tube, and each of the three sub-insulation covers has a handle fixed to its top.

[0011] Preferably, as an improvement, the first cooling duct, the cooling air passage, and the second cooling duct share a single cooling air source.

[0012] Preferably, as an improvement, mounting brackets are fixed on both sides of the supporting square tube, and slide rails are provided on the mounting brackets along the conveying direction. Mounting blocks are fixed at both ends of the driven wheel's shaft, and the mounting blocks are slidably connected to the slide rails. Lead screws are rotatably connected to both ends of the driven wheel's shaft, and nuts are fixed on the mounting brackets. The lead screws are threaded into the nuts.

[0013] Preferably, as an improvement, the bottom of the temporary storage platform is provided with casters.

[0014] Preferably, as an improvement, the length ratio of the perforated top plate to the non-perforated top plate is 3:4.

[0015] Preferably, as an improvement, a heating pipe is installed on the inner wall of the heat insulation cover, and several spray holes are evenly opened on the inner side of the heating pipe. The heating pipe is connected to a gas source.

[0016] Preferably, as an improvement, a light is provided on one side of the conveyor belt.

[0017] The principles and beneficial effects of this solution are as follows:

[0018] 1. After being removed from the bottle-making machine, glass bottles are first placed on a temporary storage platform before being transferred to a conveyor belt. While on the platform, a primary cooling mechanism utilizes cooling ducts around the platform and cooling channels at the bottom to cool the bottles from multiple directions. The primary cooling ducts blow cooling air through primary air holes, quickly removing heat from the bottle's perimeter. Additionally, because the bottom of the bottle is thicker and heat is concentrated there, cooling channels connect to cooling holes at the bottle bottom on the placement tray for targeted cooling of the bottom. During the initial stage of transport, a secondary cooling mechanism continues cooling through a second cooling duct within the supporting square tube and a second air hole at the top. This two-stage cooling process, compared to existing technologies that only cool during transport, more effectively reduces the temperature at the bottom of the bottle, minimizing deformation and cracking caused by thermal stress due to large temperature differences between the bottle body and bottom. This significantly improves cooling efficiency and quality, ensuring a high product qualification rate.

[0019] 2. This solution uses a supporting square tube to support the conveyor belt, with the drive wheel and driven wheel working together to achieve transmission. A second cooling duct is cleverly installed inside the supporting square tube, utilizing a perforated top plate to allow cooling air to act on the glass bottles. This design organically integrates cooling functionality with the transmission structure, without occupying excessive additional space, resulting in a compact equipment structure. During operation, cooling and transmission occur simultaneously, reducing process time and improving overall production efficiency. Furthermore, the supporting square tube and related components form a stable frame, providing reliable support for the conveyor belt, ensuring smooth operation during transmission, reducing the risk of collisions and tipping of glass bottles caused by belt swaying and shaking, and contributing to the safety and quality of glass bottle transmission.

[0020] 3. After the glass bottle is formed at a high temperature, it is first cooled rapidly by blowing air to reduce its temperature and prevent quality problems such as bottom deformation and thermal stress concentration caused by high temperature, thus achieving initial shaping of the glass bottle. However, the temperature of the glass bottle is still unstable after cooling. If it is directly exposed to the environment, the sudden temperature change will generate new thermal stress, affecting the quality. Therefore, this solution uses an insulation cover to maintain the temperature of the glass bottle in the non-perforated top plate section, thereby improving the stability of product quality. The inner wall of the insulation cover is equipped with a high-temperature resistant insulation layer, which can effectively block external heat exchange.

[0021] 4. The insulation cover consists of three sub-insulation covers that are detachably connected to the supporting square tube, and each has a handle at the top. This facilitates installation and disassembly. For example, during routine maintenance, repair, or replacement of parts, workers can easily lift the sub-insulation covers using the handles for quick disassembly. This allows for convenient inspection, cleaning, and repair of the interior of the insulation cover and related components of the conveyor belt, significantly reducing maintenance time and improving equipment maintainability and work efficiency.

[0022] 5. The first cooling duct, cooling air passage, and second cooling duct share a single cooling air source, reducing the purchase and installation costs of air source equipment. Simultaneously, during operation, a unified air source facilitates centralized management and maintenance, reducing energy consumption, achieving energy conservation and emission reduction, and lowering long-term operating costs.

[0023] 6. The adjustment structure, consisting of slide rails, mounting blocks, screws, and nuts on both sides of the supporting square tube, allows for flexible adjustment of the driven wheel's position on the slide rail by rotating the screw. During long-term use, the conveyor belt may loosen due to wear and stretching. This structure allows for timely adjustment of the driven wheel's position, effectively regulating the conveyor belt's tension, preventing slippage and deviation, ensuring stable operation, and guaranteeing accurate positioning of glass bottles during transport. This prevents glass bottles from colliding or falling due to conveyor belt issues.

[0024] 7. The inner wall of the insulation cover is equipped with heating pipes connected to a gas source. When needed, the glass bottle body can be heated and kept warm by spraying flames through the nozzles. This can meet the needs of various glass bottle production processes. For example, some special glass bottles need to be kept within a specific temperature range for subsequent processing after molding. The heating pipes can help achieve this requirement, thus broadening the applicability of this solution in different glass bottle production processes.

[0025] 8. The lighting on one side of the conveyor belt provides sufficient illumination, allowing workers to clearly observe the appearance of the glass bottles during transport. This enables them to promptly detect quality defects such as cracks, bubbles, pinholes, and deformation on the surface of the glass bottles, facilitating the timely removal of unqualified products.

[0026] 9. The length ratio of the perforated top plate to the non-perforated top plate is set at 3:4, which rationally divides the cooling and insulation zones on the conveyor belt. The perforated top plate, in conjunction with the second cooling duct, achieves initial cooling, while the non-perforated top plate, combined with the insulation cover, provides subsequent insulation. This length ratio makes the connection between the cooling and insulation processes more reasonable. While ensuring effective initial cooling of the glass bottles, it provides appropriate duration and space for subsequent insulation, resulting in a smoother and more reasonable temperature change of the glass bottles during transportation, optimizing the temperature control process and improving product quality stability.

[0030] The following detailed description illustrates the specific implementation method:

[0031] The reference numerals in the accompanying drawings include: conveyor belt 1, support square tube 11, support foot 12, conveyor mesh belt 13, drive wheel 14, driven wheel 15, perforated top plate 16, non-perforated top plate 17, temporary storage platform 2, placement tray 21, bottle bottom cooling air hole 22, first cooling air duct 23, first air hole 24, insulation cover 3, sub-insulation cover 31, mounting bracket 4, slide rail 41, mounting block 42, nut 43, and lead screw 44.

[0032] Example 1:

[0033] like Figure 1 and Figure 3 As shown, an automatic bottle conveyor includes a conveyor belt 1. A primary cooling mechanism is provided at the feeding end of the conveyor belt 1. The primary cooling mechanism includes a temporary storage platform 2. Rollers (not shown) are installed at the bottom of the temporary storage platform 2. A first cooling air duct 23 is fixed around the top of the temporary storage platform 2. A plurality of first air holes 24 are evenly distributed on the inner side of the first cooling air duct 23 (the side facing the center of the temporary storage platform 2). A plurality of placement trays 21 are evenly fixed on the temporary storage platform 2. Bottle bottom cooling air holes 22 are evenly distributed on the placement trays 21. A cooling air duct is installed inside the temporary storage platform 2, and the cooling air duct communicates with the bottle bottom cooling air holes 22. The first cooling air duct 23 communicates with the cooling air duct and is connected to a cooling air source. In this embodiment, the cooling air source is compressed air, which is provided by a compressor. The number of temporary storage platforms 2 is set according to actual needs. In this embodiment, there are two temporary storage platforms 2, placed on the side of the feeding end of the conveyor belt 1. Only one temporary storage platform 2 is shown in the figure.

[0034] Combination Figure 2 As shown, the conveyor belt 1 includes a supporting square tube 11, with multiple supporting legs 12 welded and fixed to the bottom of the supporting square tube 11, the multiple supporting legs 12 being evenly supported on the bottom of the supporting square tube 11. A drive wheel 14 is rotatably mounted on one end of the supporting square tube 11, the drive wheel 14 being driven by a motor, and a driven wheel 15 is rotatably mounted on the other end of the supporting square tube 11. A conveyor belt 13 is tensioned between the drive wheel 14 and the driven wheel 15, and the top of the supporting square tube 11 is supported below the top surface of the conveyor belt 13. A secondary cooling mechanism is provided on the conveyor belt 1. The secondary cooling mechanism includes a second cooling air duct installed inside the supporting square tube 11. The second cooling air duct shares a cooling air source with the first cooling air duct 23. Several second air holes are evenly opened on the top of the second cooling air duct. The top plate of the supporting square tube 11 is composed of a perforated top plate 16 and a non-perforated top plate 17. The perforated top plate 16 is located near the feeding end of the conveyor belt 1. The length ratio of the perforated top plate 16 to the non-perforated top plate 17 is 3:4. The perforated top plate 16 is located above the second cooling air duct.

[0035] A heat insulation cover 3 is installed on the non-perforated top plate 17, which is placed on the conveyor belt 13. A high-temperature resistant insulation layer made of quartz wool is fixed on the inner wall of the heat insulation cover 3. The heat insulation cover 3 includes three sub-heat insulation covers 31, which are detachably connected to the supporting square tube 11 by bolts. Handles are welded to the top of the three sub-heat insulation covers 31.

[0036] In this embodiment, the driven wheel 15 is slidably mounted on the supporting square tube 11 to adjust the tension of the conveyor belt 13. Specifically, mounting brackets 4 are welded and fixed to the two side walls of the supporting square tube 11. A slide rail 41 arranged along the conveying direction is welded to the mounting brackets 4. Mounting blocks 42 are fixed to both ends of the driven wheel 15's shaft. The mounting blocks 42 are slidably connected to the slide rail 41. A lead screw 44 is rotatably connected to both ends of the driven wheel 15's shaft. A nut 43 is welded and fixed to the mounting bracket 4. The lead screw 44 is threaded into the nut 43.

[0037] In practical application, after the glass bottle is formed, it is placed on the placement tray 21 of the temporary storage platform 2. Cooling air is delivered to the first cooling air duct 23 and the cooling air channel through pipes. The first air hole 24 on the inner side of the first cooling air duct 23 blows cooling air out to the bottom of the glass bottle, while the bottle bottom cooling air hole 22 on the placement tray 21 is connected to the cooling air channel, blowing air onto the glass bottle from the bottom, forming a cooling mode that combines the top and bottom, quickly reducing the temperature of the glass bottle, preventing problems such as deformation and thermal stress concentration due to high temperature, and initially shaping the glass bottle.

[0038] After one cooling cycle, the glass bottles are transferred to the conveyor belt 13. Driven by a motor, the drive wheel 14 rotates, causing the conveyor belt 13 to move and transport the glass bottles to the next workstation. In this embodiment, the conveying direction is... Figure 1 The direction is from right to left. When the glass bottle is conveyed on the conveyor belt 13, it first passes through the area of ​​the perforated top plate 16 of the supporting square tube 11. The cooling air source enters the second cooling air duct inside the supporting square tube 11 and blows the cooling air upward from the second air hole at the top of the second cooling air duct. The cooling air continues to cool the glass bottle through the perforated top plate 16, ensuring that the glass bottle is further cooled in the early stage of the conveying process to meet the process requirements.

[0039] After secondary cooling, the glass bottle continues to move with the conveyor belt 13 to the area of ​​the non-porous top plate 17 and enters the insulation cover 3. The quartz wool insulation layer on the inner wall of the insulation cover 3 plays a role in effectively slowing down the heat loss of the glass bottle, preventing the temperature from dropping suddenly due to environmental factors and generating new thermal stress, while meeting the temperature requirements of the subsequent annealing process, maintaining the temperature stability of the glass bottle, and ensuring product quality.

[0040] If the conveyor belt 13 becomes loose, its tension can be adjusted by changing the position of the driven wheel 15. Specifically, the operator rotates the lead screw 44. Since the lead screw 44 is threadedly connected to the nut 43, its rotation causes the driven wheel 15's shaft and mounting block 42 to slide on the slide rail 41, thereby changing the distance between the driven wheel 15 and the drive wheel 14. This restores the tension of the conveyor belt 13 to normal, ensuring smooth transport of glass bottles and preventing collisions or drops caused by belt slack.

[0041] Example 2:

[0042] The difference between this embodiment and Embodiment 1 is that a heating pipe is installed on the inner wall of the insulation cover 3. Several nozzles are evenly distributed on the inner side of the heating pipe (the side facing the conveyor belt 13), and the heating pipe is connected to a gas source. When needed, the gas source can be activated to spray flames onto the glass bottle through the nozzles on the heating pipe for insulation.

[0043] Example 3:

[0044] In this embodiment and in embodiment 2, a light is provided on one side of the conveyor belt 1. The light allows the operator to observe the appearance of the glass bottles and promptly screen out products that do not meet the appearance requirements.
