Description

Technical Field

[0001] This utility model relates to the technical field of condiment processing equipment, and in particular to an automatic preheating system for condiment bottle caps. Background Technology

[0002] Bottled condiments need to be preheated before the label is sprayed on the cap. Existing technology typically uses preheating devices, but these devices still have the following problems: 1. The preheating device has poor automation, and the heating time is usually controlled by the speed of the conveyor belt. The speed at which the bottle cap passes through the heating zone is controlled to control the heating time. However, after long-term use, the speed of the conveyor belt is not always kept at a constant speed. During on-site production, the speed often fluctuates. At this time, it is difficult to control the preheating time. Moreover, in case of unexpected situations, it is difficult to remove the bottle from the preheating device. 2. Existing preheating devices can also use low-temperature plasma treatment devices, but low-temperature plasma requires the heat source to be in direct contact with the bottle cap, which may cause the bottle cap to change color. In addition, the cost is high and there are certain requirements for the operating environment. Utility Model Content

[0003] This utility model provides an automatic preheating system for condiment bottle caps, aiming to solve the problems mentioned above, such as poor automation of existing preheating devices, inconvenient control of heating time, difficulty in removing the bottle body in case of accidents, and high cost and requirements of plasma treatment equipment.

[0016] The embodiments will be further described below with reference to the accompanying drawings.

[0017] like Figures 1-4As shown in the preferred embodiment 1, an automatic preheating system for condiment bottle caps includes a telescopic device 2 that moves vertically on one side of the conveyor belt 1. A heating cover 3 is synchronously moved on the moving end of the telescopic device 2. The opening of the heating cover 3 faces downward and is directly opposite the conveyor belt 1. An electric heating tube 4 is provided on the inner wall of the heating cover 3, and the heating cover 3 forms a heating groove 301 through the electric heating tube 4 to heat the bottle cap. A control device 7 is provided on one side of the conveyor belt 1, and a distance measuring sensor 5 is provided on the top side of the heating cover 3 to detect the vertical distance between the top of the heating cover 3 and the conveyor belt 1. A bottle cap sensing sensor 6 is provided on the top side of the conveyor belt 1 to sense the bottle cap. The telescopic device 2, the electric heating tube 4, the conveyor belt 1, the distance measuring sensor 5 and the bottle cap sensing sensor 6 are all electrically connected to the control device 7.

[0018] In the above embodiment, the telescopic device 2 and the conveyor belt 1 are linked together with the distance measuring sensor 5 and the bottle cap sensing sensor 6 through the control device 7. When the bottle cap sensing sensor 6 senses the bottle cap, the bottle cap is located directly below the heating cover 3.

[0019] In the above embodiment, the control device 7 includes a housing 701, which houses a programmable PLC controller and a timer. The outer side of the housing 701 is equipped with a display screen 702 and an operation keyboard 703. These are all existing automatic control electrical devices.

[0020] The control process is controlled by the programmable PLC controller of the control device 7. The display screen 702 is used to display the output power of the electric heating tube 4, as well as the bottle cap sensing status and the distance of the distance sensing sensor. The control process is as follows: The controller supplies power to the electric heating tube 4 according to the set power, and maintains the temperature in the range of approximately 40~50℃. At this time, the spirally arranged electric heating tube 4 forms a heat accumulation area in the heating groove 301 of the cover. At the same time, the rising and falling distance parameters and heating time are set, and the bottle body carrying the bottle cap is conveyed along the conveyor belt 1. When the bottle cap sensing device 6 detects the bottle cap, it sends a signal to the controller. After receiving the signal, the controller pauses the conveyor belt 1 and then starts the telescopic device 2 to descend, and the heating cover 3 descends synchronously. When the ranging sensor 5 detects the set distance parameter for the descent, the ranging sensor 5 sends a signal to the controller, the controller brakes the telescopic device 2 to maintain its position, and starts the timer. At this time, the bottle cap is located in the heat accumulation area without contacting the electric heating tube 4 for preheating. After the timer reaches the set duration, the controller controls the telescopic device 2 to rise. When the distance sensor 5 detects that the device has risen to the set distance parameter, the controller brakes the telescopic device 2 to maintain its position and restarts the conveyor belt 1 to wait for the next bottle cap sensing.

[0021] During the process, you only need to control the electric heating element 4 to run at the set low power. The temperature should be within this range. There is no need to control the temperature too much, as the temperature itself is already low.

[0022] In a preferred embodiment 2, a horizontally arranged mounting platform 101 is provided on one side of the conveyor belt 1, and the telescopic device 2 is mounted on the mounting platform 101 for mounting the telescopic device 2.

[0023] As a preferred embodiment 3, such as Figure 5 As shown, an opening can also be provided on the side of the conveyor belt 1 located at the installation platform 101 to avoid collisions during descent.

[0024] As a preferred embodiment 4, the telescopic device 2 includes two vertically arranged slide rods 201 on the mounting platform 101. The same slider 202 is installed on the slide rods 201. The slider 202 and the two slide rods 201 form a limiting sliding. A hydraulic cylinder 203 is provided on the mounting platform 101 on one side of the slider 202, and the output end of the slider 202 and the hydraulic cylinder 203 are linked. The other side of the slider 202 is fixedly installed with the heating cover 3.

[0025] The extension and retraction are powered by hydraulic cylinder 203. The output end of hydraulic cylinder 203 moves to drive slider 202 to move synchronously along slide rod 201 to complete the lifting and lowering action. The movement of slider 202 drives heating cover 3 to move synchronously.

[0026] In the above embodiment, the slider 202 is parallel to the conveyor belt 1. The middle position of the slider 202 on the side closer to the conveyor belt 1 is fixedly connected to the heating cover 3 through the first connecting block 204. The middle position of the slider 202 on the side away from the conveyor belt 1 is fixedly connected to the fastening sleeve 206 through the second connecting block 205. The output end of the hydraulic cylinder 203 is linked with the fastening sleeve 206 through fasteners. The fixed end base of the hydraulic cylinder 203 is fixedly installed on the installation platform 101 through fasteners.

[0027] The first connecting block 204 is perpendicular to the slider 202 and also perpendicular to the intermediate axis of the heating cover 3; The second connecting block 205 is perpendicular to the slider 202 and also perpendicular to the intermediate axis of the fastening sleeve 206.

[0028] To ensure the stability of installation and movement, and to facilitate the alignment of the heating cover 3 with the bottle cap.

[0029] In a preferred embodiment 5, the heating cover 3 is cylindrical, and a coaxial cylindrical heating groove 301 is provided at the bottom of the heating cover 3. Helically arranged electric heating tubes 4 are provided on the inner wall of the heating groove 301. When the bottle cap sensing device 6 senses the bottle cap, a gap exists between the outer periphery of the bottle cap and the inner periphery of the electric heating tubes 4. This ensures that there is no direct contact with the heat source, and the bottle cap is preheated within the heating groove 301 through radiation and hot air.

[0030] In a preferred embodiment 6, the ranging sensor 5 includes a connecting plate 501. One end of the connecting plate 501 is fixedly mounted to the top of the heating cover 3 by fasteners. The other end of the connecting plate 501 extends outward from the heating cover 3 and is provided with a first mounting base 502. A ranging sensor 503 is fixedly mounted on the first mounting base 502 by fasteners. The output / sensing end of the ranging sensor 503 faces the conveyor belt 1. Distance sensing is performed by the ranging sensor 503 to indirectly control the lifting height of the heating cover 3.

[0031] In the above embodiments, the first mounting base 502 can be integrally formed with the connecting plate 501, which facilitates installation and use, and the output / sensing end of the ranging sensor 503 does not exceed the bottom of the heating cover 3, so as to avoid conflict with the bottle body or heating.

[0032] In a preferred embodiment 7, the bottle cap sensing device 6 includes an L-shaped base 601. The L-shaped base 601 is snapped onto the top outer side of the conveyor belt 1 and fixedly engaged with the conveyor belt 1 by fasteners. A vertically arranged support rod 602 is provided at the top of the L-shaped base 601, and a second mounting seat 603 is provided at the top of the support rod 602. An infrared sensor 604 is fixedly mounted on the second mounting seat 603 by fasteners. The output / sensing end of the infrared sensor 604 is perpendicular to the conveying direction to detect bottle caps traveling along the conveying direction. The bottle cap is sensed by the infrared sensor 604. The L-shaped base 601 forms a fixed rod shape with the conveyor belt 1 and can adapt to right angles on the sides of the conveyor belt 1, facilitating installation on various conveyor belt sides. The support rod 602 is used to raise the height of the second mounting seat 603 to ensure the sensing of the bottle cap.

[0033] In the above embodiments, the bottle cap sensing device 6 is usually located on the side of the conveyor belt 1 away from the telescopic device 2 to avoid conflict with the telescopic process.

[0034] The working principle of this utility model: The controller supplies power to the electric heating tube 4 according to the set power, and maintains the temperature in the range of approximately 40~50℃. At this time, the spirally arranged electric heating tube 4 forms a heat accumulation area in the heating groove 301 of the cover. At the same time, the rising and falling distance parameters and heating time are set, and the bottle body carrying the bottle cap is conveyed along the conveyor belt 1. When the bottle cap sensing device 6 detects the bottle cap, it sends a signal to the controller. After receiving the signal, the controller pauses the conveyor belt 1 and then starts the telescopic device 2 to descend, and the heating cover 3 descends synchronously. When the ranging sensor 5 detects the set distance parameter for the descent, the ranging sensor 5 sends a signal to the controller, the controller brakes the telescopic device 2 to maintain its position, and starts the timer. At this time, the bottle cap is located in the heat accumulation area without contacting the electric heating tube 4 for preheating. After the timer reaches the set duration, the controller controls the telescopic device 2 to rise. When the distance sensor 5 detects that the device has risen to the set distance parameter, the controller brakes the telescopic device 2 to maintain its position and restarts the conveyor belt 1 to wait for the next bottle cap sensing.
