Description

Technical Field

[0001] This utility model relates to the field of heat processing monitoring technology for food or beverage packaging, specifically a device for detecting the temperature of the seam of an easy-open can. Background Technology

[0002] Aluminum cans are common metal packaging containers, primarily used for holding beverages and food. During can production and subsequent processing, such as high-temperature sterilization after beverage filling and curing after can coating, strict temperature control is required for the entire can body, especially the seams, such as rolled edges and welded edges. This is because seams are often weak points in the can's strength and sealing; uneven temperature distribution during high-temperature processing can easily lead to can deformation, coating failure, and internal pressure leakage. Therefore, during production, a furnace temperature tracking device is needed to measure the temperature at single points inside or outside the can, monitoring the temperature of the center or surface of the can to ensure the can temperature remains normal.

[0003] Traditional furnace temperature tracking devices mostly use single-point temperature measurement inside or outside the can, which can usually only monitor the temperature of the middle or surface of the can, and it is difficult to accurately sense the true temperature of the edge seam area. On the production line, the edge seam position of a single can is not easy to fix and the positioning is difficult. Conventional sensing detection methods are difficult to continuously and stably measure the temperature of the edge seam. If the edge seam temperature is abnormal, such as too low leading to incomplete sterilization, or too high causing deformation, it is often not detected in time, which poses a risk to product consistency and safety. To this end, we propose an easy-open can edge seam temperature detection device. Utility Model Content

This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this invention is to provide a device for detecting the temperature of the seam of an aluminum can, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature detection device for the seam of an aluminum can, comprising a main body, a detection bracket fixed at the top center of one side of the main body, the detection bracket including a support platform, an electric telescopic rod fixed at the bottom of one end of the support platform, a connecting platform fixed at the bottom end of the electric telescopic rod, connecting rods fixed on both sides of the bottom surface of the connecting platform, a rotating seat fixed at the bottom end of the connecting rod, a servo motor fixed at the center of the top surface of the rotating seat, a probe shaft connected to the center of the bottom surface of the rotating seat, a CCD camera fixed at the center of the bottom surface of the probe, a clamping claw mounted on the side of the bottom surface of the probe, a clamping servo motor connected to the end of the clamping claw, a patch fixed at the bottom end of the clamping claw, thermocouple sensors fixed around the inside of the patch, and an aluminum can sample attached to the inner wall of the patch.

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This utility model provides, for example Figure 1-5 The device for detecting the edge temperature of an aluminum can, as shown, includes a main body 1. A detection bracket 2 is fixed to the top center of one side of the main body 1. The main body 1 includes a device platform 101. An operation panel 102 is fixed to one side of the top of the device platform 101. A base 103 is fixed to the bottom of the device platform 101. A core processor is installed inside the device platform 101. A transmission bracket 104 is fixed to the center of one side of the device platform 101. A transmission belt 105 is mounted on the top surface of the transmission bracket 104.

[0029] To ensure stable transport and structural support for this temperature detection device on the aluminum can production line, such as Figure 1 As shown, this temperature detection device can be stably mounted on the bottom through the equipment platform 101 and the base 103 fixed to the base, while the inner wall part is fixed to the transmission bracket 104. The two ends of the transmission bracket 104 are connected to the production line, so that the transmission belt 105 mounted in the transmission bracket 104 can transport the can sample 213 on the production line, which facilitates the stable detection process of the whole equipment.

[0030] The core processor of the device is mainly mounted on a PCB board. The image acquisition card, microcontroller, PLC and CCD camera 208 soldered on the PCB board work together to precisely adjust the direction of the probe head 207 and the clamping claw 209 during the detection process, so as to stably clamp the can sample 213 and control the detection temperature in real time.

[0031] like Figure 2-5 As shown, the detection bracket 2 includes a support platform 201, and an electric telescopic rod 202 is fixed to the bottom of one end of the support platform 201. A connecting platform 203 is fixed to the bottom end of the electric telescopic rod 202, and connecting rods 204 are fixed to both sides of the bottom surface of the connecting platform 203. A rotating seat 205 is fixed to the bottom end of the connecting rod 204, and a servo motor 206 is fixed to the center of the top surface of the rotating seat 205. A probe head 207 is axially connected to the center of the bottom surface of the rotating seat 205, and a CCD camera 208 is fixed to the center of the bottom surface of the probe head 207. A clamping claw 209 is mounted on the side of the bottom surface of the probe head 207, and a clamping servo motor 210 is axially connected to the end of the clamping claw 209. A patch 211 is fixed to the bottom end of the clamping claw 209, and a thermocouple sensor 212 is fixed to the four sides of the inside of the patch 211. An aluminum can sample 213 is attached to the inner wall of the patch 211.

[0032] To provide accurate monitoring of the inner and outer seams of aluminum can sample 213, such as Figure 2-5 As shown, this temperature detection device uses a support platform 201 equipped with an electric telescopic rod 202 to raise and lower the connecting platform 203. It can work with a CCD camera 208 to identify the aluminum can sample 213 being transported directly below. The core processor controls the angle of the probe head 207 and the clamping claw 209 to align them with the edge of the aluminum can sample 213. Through the clamping of the patch 211 of the clamping claw 209 and the thermocouple sensor 212, the device can maintain the clamping and positioning of the aluminum can sample 213 while monitoring the temperature of the inner and outer walls. This provides actual data on the temperature distribution in the edge area, which can be used to optimize the heating curve, improve the heat transfer design, and reduce the defect rate.

[0033] The aforementioned electric telescopic rod 202 can drive the probe head 207 to adjust up and down. At the same time, the single-sided clamping claw 209 and the thermocouple sensor 212 are used for probe-type detection, which can be adjusted to detect different depths of the tank, thus flexibly adapting to different tank sizes and production line layouts, and has good scalability and portability.

[0034] In summary, when this temperature detection device is in use, the transmission bracket 104 first connects to the aluminum can production line, and the aluminum cans are transported by the conveyor belt 105. When the aluminum cans are transported and enter directly below the bracket platform 201, the CCD camera 208 performs image recognition on the aluminum can sample 213 passing below, and transmits the image information to the image acquisition card of the core sensor. After analysis and processing, the image is sent to the core processor for further processing. The angle of the edge seam of the aluminum can sample 213 is identified from the top surface. Subsequently, the servo motor 206 is controlled by the PLC to drive the probe head 207 to rotate, so that the clamping claw 209 on one side of the probe head 207 contacts the aluminum can sample. The angle of the seam 213 is aligned, and the adjusted angle is checked again by the CCD camera 208. Then, the electric telescopic rod 202 drives the connecting platform 203 to descend until the probe head 207 and the clamping claw 209 mounted on the bottom of the connecting platform 203 penetrate the inner and outer walls of the can sample 213. Then, the clamping servo motor 210 drives the clamping claw 209 to clamp the inner and outer walls of the can sample 213 simultaneously. At this time, the patch 211 at the end of the clamping claw 209 and the thermocouple sensor 212 simultaneously detect the temperature of the inner and outer walls of the seam and transmit the temperature data to the core processor. If the temperature does not meet the requirements, a buzzer will sound to provide an on-site warning, and the detection process is completed.

Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
