[0002] As a key component ensuring the sealing performance of a freezer, the quality of the freezer's sealing strip directly affects its insulation effect and service life. In the production process of freezer sealing strips, uniform mixing of raw materials is a crucial step in ensuring the strip's performance. Existing mixing devices lack effective fault monitoring mechanisms. If components such as the mixing motor or mixing shaft experience malfunctions during mixing, these problems are difficult to detect in a timely manner. This not only leads to uneven mixing of raw materials but may also cause further equipment damage, increasing maintenance costs and production downtime. Utility Model Content

[0005] Furthermore, the control cabinet is equipped with a timing module that is electrically connected to it. The timing value of the timing module is less than the time it takes for the stirring drive motor to rotate one revolution.

[0006] Furthermore, a synchronization plate is fixedly installed on the stirring shaft, and the synchronization plate is adjacent to the top plate; a mating sensing block that can cooperate with a proximity switch is embedded between the top and bottom surfaces of the synchronization plate; when the proximity switch senses the mating sensing block, the proximity switch sends a feedback signal to the control cabinet, and the control cabinet controls the timing module to reset the timing.

[0007] Furthermore, a set of audible and visual alarms electrically connected to the control cabinet is fixedly installed on the top surface of the top plate; when the timing value of the timing module is reached, the timing module sends a feedback signal to the control cabinet, and the control cabinet controls the audible and visual alarms to start.

This avoids interference from the unstable state at the beginning of startup on the monitoring signal, improves the accuracy of monitoring, and the sensing and monitoring mechanism is synchronously linked with the rotation of the stirring shaft. Through the combination of mechanical structure and electrical control, a closed-loop fault monitoring logic is formed, which reduces external environmental interference and ensures the stability and reliability of fault monitoring.

A set of proximity switches 1013 is fixedly installed on the top surface of the inner end of the mounting groove 1012. The proximity switches 1013 are electrically connected to the control cabinet. The proximity switches 1013 start after the stirring drive motor 105, and the delay time is determined according to the speed of the stirring drive motor 105. A timing module 1014 is provided inside the control cabinet and is electrically connected to it. The timing value of the timing module 1014 is less than the time it takes for the stirring drive motor 105 to rotate one revolution. A similar device is fixedly installed on the stirring shaft 109. Step plate 107, synchronization plate 107 and top plate 104 are adjacent to each other; a mating sensing block 1011 that can sense and cooperate with proximity switch 1013 is embedded between the top and bottom surfaces of synchronization plate 107; when proximity switch 1013 senses mating sensing block 1011, proximity switch 1013 sends a feedback signal to control cabinet, control cabinet controls timing module 1014 to reset timing; a set of audible and visual alarms 106 electrically connected to control cabinet is fixedly installed on the top surface of top plate 104; when the timing module 1014 is reached... When the timing value is 14, the timing module 1014 sends a feedback signal to the control cabinet, and the control cabinet controls the audible and visual alarm 106 to start; a mixing tank 108 is opened on the top surface of the raw material mixing shell 1; the bottom end of the stirring shaft 109 is located in the mixing tank 108, and a set of stirring blades 1010 are fixedly installed on the bottom end of the stirring shaft 109; a set of solenoid valves 102 connected to the mixing tank 108 are fixedly installed on the bottom surface of the raw material mixing shell 1; an electric heating layer 101 electrically connected to the control cabinet is fixedly installed on the outer circumference of the raw material mixing shell 1.

[0026] The working principle of this embodiment:

[0027] Raw materials for producing refrigerator sealing strips are added into the mixing tank 108. When the device is started, the control cabinet first controls the stirring drive motor 105 to start. The power of the stirring drive motor 105 is transmitted to the stirring shaft 109 through the rotating shaft, causing the stirring shaft 109 to rotate. Since the stirring blade 1010 at the bottom of the stirring shaft 109 is located in the mixing tank 108, the stirring blade 1010 rotates synchronously with the stirring shaft 109, stirring the raw materials for producing refrigerator sealing strips in the mixing tank 108. This allows different raw materials to mix with each other under the action of stirring force, achieving a uniform mixing effect. At the same time, the control cabinet can control the electric heating layer 101 to work according to the raw material mixing process requirements. The electric heating layer 101 heats the raw material mixing shell 1 and the internal mixing tank 108, adjusting the raw material temperature to a suitable range, promoting the fusion reaction between raw materials, and improving the mixing quality.

[0028] During the rotation of the stirring shaft 109, the synchronization plate 107 fixedly installed on the stirring shaft 109 rotates synchronously with the stirring shaft 109. The mating sensing block 1011 embedded in the synchronization plate 107 forms a mating relationship with the proximity switch 1013 in the mounting groove 1012. The proximity switch 1013 is electrically connected to the control cabinet, and its start time is delayed compared to the stirring drive motor 105. The delay time is set according to the speed of the stirring drive motor 105 to ensure that the sensing and monitoring mechanism starts working only after the stirring system enters a stable rotation state. When the synchronization plate 107 rotates with the stirring shaft 109 to a specific position, so that the mating sensing block 1011 is opposite to the proximity switch 1013, the proximity switch 1013 senses the mating sensing block 1011 and then sends a signal back to the control cabinet. After receiving the signal, the control cabinet controls the internal timing module 1014 to reset the timing, so that the timing module 1014 restarts the timing.

[0029] The timing module 1014 inside the control cabinet is electrically connected to the control cabinet. Its preset timing value is less than the time it takes for the stirring drive motor 105 to rotate one revolution. Under normal stirring conditions, for every revolution of the stirring shaft 109, the cooperating induction block 1011 will sense the proximity switch 1013 once, and the timing module 1014 will be reset once, and the preset timing value will not be reached. If the stirring system malfunctions, such as the stirring drive motor 105 or the stirring shaft 109 is stuck, the synchronization plate 107 and the cooperating induction block 1011 will stop rotating, the proximity switch 1013 will no longer sense the cooperating induction block 1011, and the timing module 1014 will not be reset and will continue to time. When the timing module 1014 reaches the preset timing value, the timing module 1014 will send a signal to the control cabinet, and the control cabinet will then control the audible and visual alarm 106 on the top plate 104 to start. The alarm will promptly remind the operator that the equipment is abnormal through sound and light, so that the operator can quickly troubleshoot the fault and avoid equipment damage or affecting the mixing quality of raw materials.

[0030] Once the raw materials have been thoroughly mixed in the mixing tank 108 and meet the process requirements, the operator can open the solenoid valve 102 at the bottom of the raw material mixing shell 1 through the control cabinet. The mixed raw materials are then discharged through the communication channel between the solenoid valve 102 and the mixing tank 108, completing one raw material mixing operation.
