[0001] This utility model relates to the field of ventilation and temperature control technology in industrial plants, and in particular to a linkage mechanism between an automatic lifting door and an air curtain machine in a combined workshop. Background Technology

[0002] In the daily production and operation of the joint workshop, automatic lifting doors and air curtains are core equipment to ensure the smooth flow of logistics and environmental control.

[0003] However, in the existing technology, the two lack an effective linkage control mechanism: when the automatic lifting door is closed, the air curtain machine continues to run, and the equipment heats up severely due to long-term high-load operation, which poses safety hazards such as circuit aging and mechanical failure; in the case of cargo loading and unloading, the air curtain machine cannot start synchronously when the automatic lifting door is opened, and the high-temperature airflow or dust from the outside will quickly rush into the workshop, causing an imbalance in indoor temperature and humidity, affecting the comfort of the workers; therefore, in order to solve the above problems, this device proposes a linkage mechanism that combines the automatic lifting door and the air curtain machine in the workshop. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a linkage mechanism between an automatic lifting door for workshops and an air curtain machine.

[0007] A lifting door, wherein the lifting door is mounted on a door frame mounting bracket;

[0008] An air curtain machine, which is installed on the door frame mounting bracket at the top of the lifting door;

[0009] A control mechanism is mounted on the door frame mounting bracket and is used to control the start / stop of the air curtain machine.

[0010] When the lifting door is open, the control mechanism starts the air curtain machine; when the lifting door is closed, the control mechanism stops the air curtain machine.

[0011] The above technical solution further includes: the control mechanism includes a controller and a limit switch, the air curtain machine and the limit switch are electrically connected to the controller respectively, and a trigger component is installed on the lifting door. When the trigger component presses against the contact of the limit switch, the limit switch sends a control signal to the controller.

[0012] Furthermore, the triggering component includes a mounting bracket and a top wheel, the top wheel being rotatably mounted on the mounting bracket, and the contacts of the limit switch being located on the movement path of the top wheel.

[0013] Furthermore, a slide is fixedly installed on the outer wall of the lifting door, and a slider is fixedly installed on the outer wall of the mounting bracket. The slider is slidably connected to the inner wall of the slide. Two fixing plates are fixedly installed on the side wall of the slider. A set screw is threaded on the fixing plate, and the end of the set screw is movably pressed against the side wall of the slide.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this utility model, a control mechanism is provided, which enables the air curtain machine to automatically stop working when the automatic lifting door closes, avoiding the problem of overheating caused by prolonged operation of the equipment; when the automatic lifting door opens, the air curtain machine starts simultaneously and forms an airflow barrier, effectively blocking external heat, dust and other pollutants from entering the workshop, maintaining stable indoor temperature and humidity, and improving the comfort of personnel.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1

[0024] See attached document Figure 1-4 It includes: a lifting door 10, an air curtain machine 20, and a control mechanism. When the lifting door 10 is in the open state, the control mechanism controls the air curtain machine 20 to start; when the lifting door 10 is in the closed state, the control mechanism controls the air curtain machine 20 to stop running.

[0025] The control mechanism is mounted on the door frame mounting bracket and is used to control the start / stop of the air curtain machine 20; the lifting door 10 is mounted on the door frame mounting bracket; and the air curtain machine 20 is mounted on the door frame mounting bracket at the top of the lifting door 10.

[0026] In one embodiment of this utility model, the control mechanism includes a controller 31 and a limit switch 32. The air curtain machine 20 and the limit switch 32 are electrically connected to the controller 31. A trigger component is installed on the lifting door 10. When the trigger component presses against the contact of the limit switch 32, the limit switch 32 sends a control signal to the controller 31. Specifically, when the lifting door 10 is rising and opening, the lifting door 10 will drive the trigger component to move upward. During the upward movement of the trigger component, it will press against the contact of the limit switch 32. The limit switch 32 transmits an electrical signal to the controller 31, and the controller 31 controls the air curtain machine 20 to start. When the lifting door 10 is falling and closing, the lifting door 10 will drive the trigger component to move downward synchronously. During the downward movement of the trigger component, it will press against the contact of the limit switch 32. The limit switch 32 transmits an electrical signal to the controller 31, and the controller 31 controls the air curtain machine 20 to close.

[0027] In one embodiment of this utility model, the triggering component includes a mounting bracket 331 and a top wheel 33. The top wheel 33 is rotatably mounted on the mounting bracket 331, and the contacts of the limit switch 32 are located on the moving path of the top wheel 33. The top wheel 33 is cylindrical and is rotatably mounted on the mounting bracket 331. When the top wheel 33 presses against the contacts of the limit switch 32, the top wheel 33 can rotate, reducing the friction between itself and the contacts of the limit switch 32 and improving the protection of the contacts of the limit switch 32.

[0028] In one embodiment of this utility model, a slide 332 is fixedly installed on the outer wall of the lifting door 10, and a slider 333 is fixedly installed on the outer wall of the mounting bracket 331. The slider 333 is slidably connected to the inner wall of the slide 332. Two fixing plates 334 are fixedly installed on the side wall of the slider 333. A set screw 335 is threaded on the fixing plate 334, and the end of the set screw 335 is movably pressed against the side wall of the slide 332. Here, the position of the top wheel 33 can be adjusted during installation so that the position of the top wheel 33 adapts to the position of the limit switch 32 contact. When adjusting the position of the top wheel 33, the set screw 335 can be rotated counterclockwise to release the fixation of the set screw 335 to the fixing plate 334, thereby releasing the fixation of the slider 333 and the mounting bracket 331. After moving the position of the mounting bracket 331, the position of the top wheel 33 can be moved.

[0029] In this embodiment, the working principle of the device is as follows: when the automatic lifting door 10 rises and opens, the lifting door drives the trigger component to move upward synchronously. The top wheel 33 in the trigger component moves upward along the moving path of the limit switch 32 contact. When the top wheel presses against the limit switch contact, the limit switch 32 sends an electrical signal to the controller 31. After receiving the signal, the controller controls the air curtain machine 20 to start. The air curtain machine forms an airflow barrier to block external hot air, dust and other particles from entering the workshop.

[0030] When the automatic lifting door 10 descends and closes, the lifting door drives the trigger component to move downward synchronously. The top wheel 33 presses the contact of the limit switch 32 again. The limit switch sends another electrical signal to the controller 31, and the controller controls the air curtain machine 20 to stop running, so as to avoid the equipment from working under high load for a long time.

[0031] In the triggering assembly, the top wheel 33 is rotatably mounted on the mounting bracket 331. It can rotate when pressing the limit switch contact to reduce friction and protect the contact. The mounting bracket 331 is slidably connected to the slide 332 via the slider 333. During adjustment, the set screw 335 can be rotated counterclockwise to release the fixing plate 334, thereby adjusting the position of the mounting bracket 331 and the top wheel 33 to adapt to the position of the limit switch 32 contact. After adjustment, the set screw 335 can be tightened clockwise to fix it. Through the above linkage mechanism, the automatic lifting door and the air curtain machine work together, ensuring the stability of the environment and the safety of the equipment in the workshop.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
