[0020] The inventors of the present application have discovered that when applying decals to glass bottles, it is necessary to first brush hot water on the surface of the bottle and heat the surface of the bottle; however, there are obvious limitations in actual operation. First, the manual heating method cannot ensure that the temperature of the bottle body is uniform, which can easily lead to local overheating or overcooling of the bottle body, resulting in the decal paper being too hard to be positioned, and the problem of cracked labels can easily occur, which seriously affects the quality of the final product. Secondly, the manual application of hot water is slow in operation and is difficult to meet the needs of large-scale production.

The temperature control device is used to maintain a stable temperature in the heating box 2. Before applying a sticker on the surface of the glass bottle, the glass bottle is conveyed to the heating box 2 by the conveying device 11 to preheat the glass bottle as a whole.

[0021] Reference Figure 2 , 3The temperature control device includes an insulation layer 21, a heating tube 22, an electric control system 23 and a first temperature sensor 24. The insulation layer 21 is attached to the side wall of the heating box 2 and is made of aluminum foil with high reflectivity to reduce heat loss. The heating tube 22 is fixed on the inner wall of the insulation layer 21 and is made of high-temperature resistant nickel-chromium alloy wire to ensure long-term stable operation. The electric control system 23 is electrically connected to the heating tube 22 to control the power of the heating tube 22. The heating rate can be adjusted by adjusting the current. The first temperature sensor 24 is arranged in the heating box 2 and is a PT100 platinum resistance temperature sensor with high precision and fast response. The first temperature sensor 24 is electrically connected to the electric control system 23 to monitor the temperature in the heating box 2 in real time, and transmit the monitored temperature signal to the electric control system 23 to control the power of the heating tube 22 to ensure that the temperature in the heating box 2 is stable and controlled within the set range.

At the same time, the rising process of the bubbles can also increase the contact area between water and air, which helps to quickly dissipate heat and prevent the water temperature from being too high, thereby not only improving the heating efficiency, but also ensuring the uniform application of hot water, and further improving the heating effect on the surface of the glass bottle.

[0024] Reference Figure 2 , 6 A water brushing mechanism 4 is provided in the heating box 2, and the water brushing mechanism 4 is connected to the water tank 3 and is used to brush hot water onto the surface of the glass bottle. After the glass bottle enters the heating box 2 and is preheated as a whole, the hot water in the water tank 3 is brushed onto the surface of the glass bottle through the water brushing mechanism 4, thereby achieving uniform heating of the surface of the glass bottle, avoiding heat exchange between the hot water and the glass bottle itself after being brushed onto the glass bottle, thereby causing the glass bottle to be overheated or overcooled, making it difficult to position the decal paper or causing cracks in the label, thereby improving the decal quality.

[0025] Reference Figure 6 The water brushing mechanism 4 includes a mounting frame 41, a brush frame 42, a first driving member 43, a brush 44 and a water delivery assembly.

The brush frame 42 is slidably arranged on the mounting frame 41 along the vertical direction. The brush 44 is fixedly arranged on the brush frame 42. The first driving member 43 adopts a rodless cylinder. The rodless cylinder is fixedly arranged on the mounting frame 41, and the piston rod of the rodless cylinder is fixedly connected to the brush frame 42 for driving the brush frame 42 to slide.

The water pump 45 is installed on the water tank 3 and adopts a centrifugal pump with large flow and stable pressure. The water inlet end of the water pump 45 is connected with a water inlet pipe 451. The water inlet pipe 451 extends into the water tank 3, and the end of the water inlet pipe 451 away from the water pump 45 is close to the bottom wall of the water tank 3. One end of the water guide pipe 46 is connected with the water outlet end of the water pump 45, and the other end of the water guide pipe 46 is connected with the water inlet 4412 of the mounting ring 441. The water guide pipe 46 is made of PVC material with good flexibility and anti-aging. The hot water in the water tank 3 is transported to the cavity 4411 of the mounting ring 441 through the water pump 45 and the water guide pipe 46, and then flows out from the water outlet 4413 of the mounting ring 441, thereby soaking the surface of the brush 44. The brush 44 is set in a ring shape so that the hot water is evenly brushed on the surface of the glass bottle.

[0028] Reference Figure 6 A photoelectric sensor 47 is also provided on the mounting frame 41. The photoelectric sensor 47 is used to detect the position of the glass bottle. The photoelectric sensor 47 is electrically connected to the electronic control system 23. The electronic control system 23 is electrically connected to the conveying device 11, the rodless cylinder and the water pump 45 respectively. When the glass bottle is transported to the position of the brush rack 42, the photoelectric sensor 47 monitors the position of the glass bottle and controls the conveying device 11 to stop through the controller, so that the glass bottle is stationary under the brush rack 42. After that, the control system controls the water pump 45 to start, and the hot water in the water tank 3 is transported to the cavity 4411 of the mounting ring 441, and then flows out from the water outlet 4413 of the mounting ring 441 and soaks the surface of the brush 44. At the same time, the rodless cylinder is controlled to start, driving the brush rack 42 to slide downward first, and then slide upward, and the hot water is brushed onto the surface of the glass bottle through the brush 44. When the hot water is brushed on the surface of the glass bottle, the control system controls the conveying device 11 to start again, and the next glass bottle is brushed with hot water.

When the glass bottle moves to the position of the painting frame 42, the servo cylinder is first controlled by the electric control system 23 to start, drive the clamping frame 48 to slide down, put the clamping ring 481 on the glass bottle, and press the glass bottle through the soft rubber pad 482, increase the stability of the glass bottle, and ensure that the glass bottle will not move during the process of painting hot water.

[0030] The implementation principle of a heating conveyor line used for glass bottle decals in an embodiment of the present application is as follows: the power of the heating tube 22 is controlled by the electronic control system 23 to adjust the temperature in the heating box 2; before decals are applied to the surface of the glass bottles, the glass bottles are conveyed to the heating box 2 by the conveying device 11 to preheat the glass bottles as a whole; the power of the electric heater 31 is controlled by the electronic control system 23 to heat the water in the water tank 3 so that the water temperature in the water tank 3 is consistent with the temperature in the heating box 2.

[0031] During the preheating process of the glass bottle, the conveying device 11 conveys the glass bottle to the position of the brush rack 42, the photoelectric sensor 47 monitors the position of the glass bottle, and controls the conveying device 11 to stop through the controller, so that the glass bottle is stationary under the brush rack 42, and the servo cylinder is controlled to start through the electronic control system 23 to drive the clamping frame 48 to slide down, and the clamping ring 481 is set on the glass bottle, and the glass bottle is clamped by the soft rubber pad 482, and then the control system controls the water pump 45 to start, and the hot water in the water tank 3 is conveyed to the cavity 4411 of the mounting ring 441, and then flows out from the water outlet 4413 of the mounting ring 441 and soaks the surface of the brush 44, and at the same time, the rodless cylinder is controlled to start, driving the brush rack 42 to slide downward first, and then upward, and the hot water is brushed to the surface of the glass bottle through the brush 44, thereby achieving uniform heating of the surface of the glass bottle.

[0032] After the hot water is applied to the surface of the glass bottle, the clamping ring 481 is separated from the glass bottle, and the control system controls the conveying device 11 to start again, and the next glass bottle is subjected to the hot water application process; by preheating the glass bottle before applying the hot water, it is avoided that the hot water will not exchange heat with the glass bottle itself after being applied to the glass bottle, thereby causing the glass bottle to be overheated or overcooled, making it difficult to position the decal or causing the label to crack, thereby improving the decal quality. At the same time, the automated heating and application process replaces the traditional manual operation, improves the production speed, and meets the needs of large-scale production.
