Description

Technical Field

[0001] This application relates to the technical field of glass bottle manufacturing, and in particular to a cold-end spraying machine for glass bottle manufacturing. Background Technology

[0002] Glass is a commonly used material in modern life and can be made into various utensils, containers, and flat glass. In the glass bottle production and processing industry, a protective layer needs to be sprayed onto the outer wall of the glass bottle using spraying equipment to achieve both decorative and protective effects. Various spraying effects enhance the appearance of the product.

[0003] In existing technology, spraying equipment includes a conveyor belt and a spray nozzle. The conveyor belt transports glass bottles, and the spray nozzle is installed above the conveyor belt and facing the glass bottles. When the conveyor belt is running, paint is sprayed outward through the spray nozzle to act on the glass bottles, thereby coating a protective layer on the outer wall of the glass bottles. However, if spraying is performed directly on freshly processed glass bottles, the high surface temperature of the glass bottles will cause the paint to evaporate rapidly, affecting the uniformity and adhesion of the coating, thus reducing the protective effect. In addition, spraying in a high-temperature environment may also cause defects such as paint blistering and sagging. Since the ends of the glass bottles cool down relatively quickly, even with one-piece spraying, the appearance quality of the product will be seriously affected. Therefore, further improvements are needed. Utility Model Content

[0004] To address the above problems, this application provides a cold-end spraying machine for the preparation of glass wine bottles.

[0005] This application provides a cold-end spraying machine for glass bottle manufacturing, which adopts the following technical solution: A cold-end spraying machine for glass bottle manufacturing includes a frame, a conveyor belt mounted on the frame for transporting glass bottles, a spraying mechanism mounted on the frame, and a temperature detection mechanism mounted on the frame. The temperature detection mechanism includes multiple infrared temperature probes spaced apart along the length of the frame, with different heights to detect the temperature at different heights of the glass bottles. The infrared temperature probes are electrically connected to a host computer, which processes the data measured by the probes. The host computer is also electrically connected to a controller, which executes instructions sent by the host computer based on the processed data. The controller is electrically connected to the spraying mechanism, which includes multiple spray frames spaced apart along the length of the frame and spray nozzles mounted on the spray frames, with different heights for each nozzle.

[0006] By adopting the above technical solution, in the glass bottle manufacturing process, this cold-end spraying machine uses a conveyor belt on the frame to transport glass bottles. Multiple infrared temperature probes, spaced apart along the length of the frame, accurately detect the temperature at different heights of the glass bottles. The detected data is transmitted to a host computer for processing. The host computer then sends instructions to a controller, which in turn controls the spraying mechanism. The multiple spraying frames spaced apart along the frame allow for targeted spraying based on the temperature at different heights of the glass bottles. This reduces the problems of rapid paint evaporation, coating uniformity, and adhesion issues caused by direct spraying on high-temperature glass bottles. It also reduces defects such as blistering and sagging caused by high-temperature spraying, improving the protective effect of the coating and the product's appearance quality.

[0007] Preferably, the spraying frame slides along the length of the frame, and the spraying mechanism further includes a fixing component to limit the sliding of the spraying frame.

[0008] By adopting the above technical solution, since different bottles require different amounts of time to dissipate heat, and the conveying speed of our transmission belt is relatively fixed, the horizontal position of the spraying frame can be adjusted as needed by sliding the spraying frame along the length of the frame, and then fixed by the fixing components.

[0009] Preferably, the lower end of the spraying frame is fixedly connected to a first slider, and the upper surface of the frame is provided with a first sliding groove for the first slider to slide and connect. The fixing assembly includes a fixing plate connected to the first slider and a fixing bolt threaded through the fixing plate. The fixing bolt is threadedly connected to the frame.

[0010] By adopting the above technical solution, specifically through the first slider and the first slide groove, the sliding of the spraying frame is realized. The first slider is restricted by fixing bolts passing through the fixing plate to connect with the machine frame by threads.

[0011] Preferably, the infrared temperature probe is disposed on the spraying frame, and the spraying frame and the infrared temperature probe are misaligned.

[0012] By adopting the above technical solution, the infrared temperature probe is placed on the spraying rack, providing a mounting carrier for the infrared temperature probe, thereby reducing the cost of having to set up a separate mounting carrier.

[0013] Preferably, both the infrared temperature probe and the spray head are connected to a second slider, and a second groove is provided on the surface of the spray frame near the conveyor belt. The second slider is slidably connected to the second groove, and a limiting member is provided on the spray frame to restrict the sliding connection of the second slider.

[0014] By adopting the above technical solution, since the height of the bottles to be sprayed varies, the height positions of the infrared temperature measuring probe and the spray head also vary. To achieve this requirement, the second slider is slidably connected to the second slide groove, and then the limiting component is used to limit the movement, so that it can be adjusted according to the requirements, thereby improving the adaptability of the spraying machine.

[0015] Preferably, the second chute is provided along the entire length of the spraying frame in the height direction.

[0016] By adopting the above technical solution, the number of spray nozzles and infrared temperature probes required varies depending on the height of the bottle. Therefore, in order to meet the requirements, the second chute is set along the entire length of the spray frame.

[0017] Preferably, the frame is provided with an air cooling mechanism, which includes an air outlet pipe disposed on the spray frame and a gas nozzle connected to the air outlet pipe. A plurality of gas nozzles are disposed along the length of the frame, and the gas nozzles are offset from the spray head.

[0018] By adopting the above technical solution, an air-cooling mechanism is installed on the frame, and several air outlet pipes of the air-cooling mechanism are set on the spray frame and staggered from the spray head. When the glass bottle is being sprayed, the air blown out by the air outlet pipes can cool the glass bottle, reducing the rapid evaporation of paint caused by the high surface temperature of the glass bottle, which affects the uniformity and adhesion of the coating, thereby improving the protective effect. At the same time, it reduces defects such as paint blistering and sagging caused by spraying in high temperature environment. Moreover, the staggered setting can not affect the spraying operation of the spray head while cooling, ensuring the normal operation of the spraying work and helping to improve the appearance quality of the product.

[0019] Preferably, the gas nozzle is also connected to a second slider, which also limits the height position of the gas nozzle through the limiting member.

[0020] By adopting the above technical solution, a second slider is also provided for the gas nozzle, so that the height position of the gas nozzle can be adjusted as needed to improve the cooling effect on the glass bottle.

[0021] In summary, this application has the following beneficial effects: The temperature at different heights of the glass bottle is detected by a temperature detection mechanism. After the data is processed by the host computer, the controller controls the spraying mechanism to reduce spraying at high temperatures, improve the uniformity and adhesion of the coating, and enhance the protective effect.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0025] This application discloses a cold-end spraying machine for the preparation of glass wine bottles.

[0026] Example 1: A cold-end spraying machine for glass bottle manufacturing, as described in the following figure. Figure 1 , Figure 2 It includes a frame 1, a conveyor belt 2 mounted on the frame 1 for transporting glass bottles, a drive mechanism 3 for driving the conveyor belt 2, a spraying mechanism 4 mounted on the frame 1, and a temperature detection mechanism 5 mounted on the frame 1.

[0027] Specifically, the drive mechanism 3 includes a transmission roller 31 rotatably connected to the frame 1 and a first drive motor 32 for driving the transmission roller 31 to rotate. At least two transmission rollers 31 are provided and are respectively provided at both ends of the frame 1 for the conveyor belt 2 to be wound around. The first drive motor 32 is fixedly connected to the side wall of the frame 1, and the output shaft of the first drive motor 32 is rotatably passed through the frame 1 to be fixedly connected to one of the transmission rollers 31.

[0028] The spraying mechanism 4 includes a spraying frame 41 that is slidably connected to the frame 1, a fixing component 42 that restricts the sliding of the spraying frame 41, a nozzle 43 disposed on the spraying frame 41, and a conveying component 44 connected to the nozzle 43 for conveying paint.

[0029] In this embodiment, several spraying frames 41 are spaced apart along the length of the frame 1. The spraying frames 41 are mounted on the frame 1, and their length is parallel to the width of the frame 1. The spraying frames 41 are slidably connected to the frame 1. A first slider 411 is fixedly connected to the lower end of the spraying frame 41. A first groove 11 is provided on the upper surface of the frame 1 for the first slider 411 to slide and connect. The fixing component 42 specifically includes a fixing plate 421 fixedly connected to the first slider 411 and a fixing bolt 422 threaded through the fixing plate 421. Threaded holes for the fixing bolt 422 to be threadedly connected are provided on the upper surface of the frame 1 or the inner bottom wall of the first groove 11. The threaded holes are spaced apart along the length of the frame 1. By rotating the fixing bolt 422, it can be threadedly connected to the threaded hole or directly pressed against the inner bottom wall of the first groove 11 to restrict the sliding of the first slider 411, thereby fixing the horizontal position of the spraying frame 41.

[0030] Reference Figure 3 In another embodiment, the fixing component 42 further includes a limiting strip 423 fixed to the fixing bolt 422. The length of the limiting strip 423 is longer than the width of the first slide groove 11. By rotating the fixing bolt 422, the two ends of the limiting strip 423 are respectively driven to abut against the two opposite inner sides of the first slide groove 11, thereby restricting the sliding of the spray frame 41.

[0031] Back Figure 1 , Figure 2 The nozzles 43 are spaced apart along the height of the spray frame 41, and are located on both sides of the spray frame 41. The conveying assembly 44 includes a conveying pipe 441 connected to a plurality of nozzles 43 located in the same vertical direction and a control pump 442 disposed on the conveying pipe 441. The control pump 442 is externally connected to a paint tank containing paint through a pipeline.

[0032] The temperature detection mechanism 5 includes multiple infrared temperature probes 51 spaced apart along the length of the frame 1, and also several infrared temperature probes 51 arranged along the height direction. These probes 51 are mounted on the spray frame 41 and offset from the spray nozzle 43. The infrared temperature probes 51 are used to detect the temperature at different heights of the glass bottle. They are electrically connected to a host computer, which processes the data measured by the probes. The host computer is also electrically connected to a controller, which executes commands sent by the host computer based on the processed data. The controller is electrically connected to a control pump 442, thereby controlling the spraying of the spray nozzle 43. Since the host computer and controller are existing technologies, they will not be described in detail here.

[0033] Furthermore, since there are glass bottles of different heights, in this embodiment, the nozzle 43 and the infrared temperature probe 51 are adjustable in the height direction. Specifically, both the nozzle 43 and the infrared temperature probe 51 are connected to a second slider, and the spray frame 41 has a second groove 412 on the side wall near the conveyor belt 2. The second slider is slidably connected to the second groove 412. The spray frame 41 is provided with a limiting member 413 that restricts the sliding connection of the second slider. The limiting member 413 can be set with reference to the fixing component 42 to fix the height position of the second slider.

[0034] In this embodiment, the second slide 412 is provided along the entire height direction of the spray frame 41 so as to provide a corresponding number of spray nozzles 43 and infrared temperature probes 51 as needed. For the delivery pipe 441 connected to the spray nozzle 43, in order to reduce the impact on the second slider during sliding, a through groove 414 is provided on the side wall of the spray frame 41. The length direction of the through groove 414 is parallel to the height direction of the spray frame 41 so that the delivery pipe 441 can pass through the through groove 414. In this embodiment, the delivery pipe 441 is a flexible hose, specifically a corrugated flexible hose.

[0035] Regarding the height positioning of the spray nozzles 43 and the infrared temperature probe 51, in this embodiment, they are specifically positioned corresponding to the bottle mouth, the middle of the bottle body, and the bottom of the bottle. Three spray nozzles 43 are correspondingly positioned along the conveyor belt 2, corresponding to the bottle mouth, the bottom of the bottle, and the middle of the bottle body, respectively. Therefore, the number of spray racks 41 is three. The infrared temperature probe 51 can also be positioned similarly to the spray nozzles 43, but in a staggered manner. Specifically, an additional spray rack 41 is provided for the initial placement of the infrared temperature probe 51.

[0036] The implementation principle of a cold-end spraying machine for glass bottle manufacturing according to an embodiment of this application is as follows: This embodiment uses a temperature detection mechanism 5 to comprehensively detect the temperature at different locations on the glass bottle. After the host computer processes the temperature data, the controller controls the spraying mechanism 4 to perform spraying according to instructions, reducing problems with coating uniformity and adhesion caused by high-temperature spraying, as well as defects such as paint blistering and sagging. Simultaneously, the arrangement of multiple nozzles 43 and spraying racks 41 enables more precise spraying, improving the product's appearance quality, representing a significant improvement over existing technologies.

[0037] Example 2: Reference Figure 4The difference from Embodiment 1 is that a cooling mechanism 6 is provided on the frame 1. The cooling mechanism 6 includes an air outlet pipe 61 disposed on the spray frame 41 and a gas nozzle 62 disposed at the air outlet end of the air outlet pipe 61. Several air outlet pipes 61 are spaced apart along the length of the frame 1. The air outlet end of the air outlet pipe 61, i.e., the gas nozzle 62, is offset from the spray head 43. In this embodiment, three gas nozzles 62 are provided, each corresponding to an infrared temperature sensor 51. In this embodiment, the air outlet pipe 61 is a flexible hose, specifically a corrugated flexible hose. An air pump is connected to the air outlet pipe 61, and the air pump is electrically connected to the controller.

[0038] The gas nozzle 62 is also connected to a second slider, and the height position of the gas nozzle 62 is limited by the limiting member 413.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
