Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling, in particular to a cooling device. BACKGROUND

[0002] The detachable leg assembly is a furniture part convenient to disassemble and assemble, which is mainly used for the support structure of furniture such as chairs. The detachable leg assembly is usually composed of a five-star leg and a plurality of tubular and front-back through detachable legs. The five-star leg includes a cylindrical fixing sleeve and a plurality of hollow tubular mounting legs. The detachable leg sleeve is arranged on the other end of the mounting leg and is detachably fixedly connected with the mounting leg. This structure makes the detachable leg have the advantages of convenient disassembly and assembly and facilitating transportation. However, in the actual production process, the cooling of the five-star leg has always been one of the key links restricting the efficiency of the product. The five-star leg is relatively soft after being injection molded and cannot be machined, so it must be fully cooled.

[0003] At present, the commonly used cooling methods for the five-star leg include natural cooling, water cooling and air cooling. These three cooling methods all need a large cooling space for the five-star leg to be fully cooled, which is not convenient for automatic production in the production site and affects the production efficiency. CONTENT OF THE INVENTION

[0004] Therefore, the present application provides a cooling device which can fully cool the five-star leg and has high cooling efficiency.

[0005] The present application provides a cooling device, which comprises a cooling table, a positioning column fixedly connected with the cooling table, and a jacking mechanism. The positioning column is slidingly connected with a supporting plate. The supporting plate has opposite supporting surfaces and a stress surface. The jacking mechanism can apply force to the stress surface to make the supporting plate slide along the positioning column.

[0006] By adopting the technical scheme of the present application, the rapid positioning and cooling height change of the five-star leg are realized through the sliding design of the jacking mechanism and the supporting plate. Compared with the traditional cooling method, the device can reduce the time and space required for cooling the five-star leg, which makes the production site more compact and orderly arranged, thereby speeding up the production rhythm, improving the production efficiency, and being conducive to realizing automatic production and lean management.

[0007] In some embodiments, the jacking mechanism comprises a push rod and a first driving member. The cooling table is provided with a through hole through which the push rod passes and is connected with the stress surface. The first driving member drives the push rod to slide along the through hole to push the supporting plate to slide.

[0008] By adopting the technical scheme of the present application, the jacking mechanism is simple and compact in structure, easy to install and deploy in limited space. By adjusting the output force of the first driving member and the stroke of the push rod, the jacking height and speed of the supporting plate can be accurately controlled to meet different application requirements. In addition, the cooperation design of the push rod and the through hole can also ensure the stability and reliability of the jacking process, and the first driving member and the push rod jacking end can be conveniently arranged on the upper and lower surfaces of the cooling table, and the structure is more reasonable.

[0009] In some embodiments, a base is also included, and the jacking mechanism further includes a screw rod, a guide rod, a push plate, and a bracket, the bracket is fixedly connected with the base, the guide rod is fixedly connected with the bracket, the push plate is slidingly connected with the guide rod and threadedly connected with the screw rod, the push rod is fixedly connected with the push plate and slidingly connected with the bracket, and the first driving member is connected with the screw rod to drive the screw rod to rotate.

[0010] By adopting the above technical scheme, the threaded connection design of the screw rod and the push plate makes the jacking process more stable and reliable. By adjusting the rotation speed and direction of the screw rod, the sliding stroke, direction, and speed of the push plate can be accurately controlled to meet different application requirements. In addition, the design of the guide rod and the bracket also enhances the stability and load-bearing capacity of the entire mechanism. Through the cooperative work of the screw rod, the guide rod, the push plate, and the bracket, accurate and stable jacking operation of the supporting plate is realized.

[0011] In some embodiments, the positioning column is a hollow circular tube structure, one end of the positioning column away from the cooling table is closed, and the other end close to the cooling table is in communication with a cooling hole on the cooling table, and the cooling hole penetrates through the upper and lower surfaces of the cooling table.

[0012] By adopting the above technical scheme, the cooling medium can enter the hollow circular tube of the positioning column through the cooling hole to cool, and the fixing sleeve of the five-star foot is sleeved outside the hollow circular tube, so that the positioning column can exchange heat with the five-star foot to reduce the temperature of the five-star foot.

[0013] In some embodiments, the side wall of the positioning column is provided with a plurality of air outlet holes penetrating through the side wall.

[0014] By adopting the above technical scheme, the cooling medium can be discharged through the air outlet hole to cool the five-star foot, and the cooling efficiency is higher.

[0015] In some embodiments, the end of the positioning column away from the cooling table has a guide surface.

[0016] By adopting the above technical scheme, the guide surface facilitates the sleeving of the five-star foot on the positioning column.

[0017] In some embodiments, the cooling table is connected with a second driving member for driving the rotation of the cooling table, and the cooling device has a feeding station and a taking station.

[0018] By adopting the above technical solution, the five-star foot can be rotated from one station (such as the feeding station) to another station (such as the taking station), thereby realizing seamless connection in the automatic production process. This automatic operation not only improves production efficiency, but also reduces manual intervention and production cost. The rotation design also helps to optimize the cooling effect. When the cooling table rotates, different parts of the five-star foot can be in turn in contact with the cooling medium, and the heat on the five-star foot can be more evenly cooled, thereby improving the cooling efficiency and uniformity and further improving the cooling effect. In actual application, the feeding station and the taking station are usually designed as two fixed positions on the cooling device. The feeding station is used to place the five-star foot to be cooled, and the taking station is used to take out the five-star foot that has been cooled. By controlling the rotation of the cooling table, the five-star foot can be ensured to be moved from the feeding station to the taking station at the right time, thereby realizing automation and continuity of the entire production process.

[0019] In some embodiments, a feeding sensor is arranged at the feeding station, and a taking sensor is arranged at the taking station.

[0020] By adopting the above technical solution, the feeding sensor is installed on the feeding station, and its main function is to detect whether the five-star foot has been correctly placed on the feeding station. When the five-star foot is placed on the feeding station, the feeding sensor will send a signal that the five-star foot has arrived and the driving of the sliding of the supporting plate and the cooling can be started. This signal can trigger the control system of the cooling device to start the corresponding program, such as starting the second driving member to rotate the cooling table to the feeding station, or starting the cooling medium circulation system, etc. Similarly to the feeding sensor, the taking sensor is installed on the taking station, which is used to detect whether the five-star foot has been cooled and is ready to be taken out. When the five-star foot completes the cooling process on the cooling table and rotates to the taking station, the taking sensor will send a signal that the five-star foot is ready to be taken out. This signal can trigger the control system to stop the cooling program, such as closing the cooling medium circulation system, or starting the taking mechanism to take out the five-star foot from the taking station. Through the cooperation of the feeding sensor and the taking sensor, the cooling device can realize more automatic and intelligent operation. These two sensors not only improve the operation accuracy of the device, but also reduce the need for manual intervention, thereby improving the production efficiency. In addition, the sensors can also provide valuable data for the maintenance and fault detection of the device, such as the accuracy of the placement position of the five-star foot, the stability of the cooling time, etc.

[0021] In some embodiments, the material taking station and the material placing station are each provided with the jacking mechanism, the cooling table is circumferentially distributed with at least three positioning columns around the rotation center, and two jacking mechanisms are arranged to correspond to any two adjacent positioning columns in the material taking station and the material placing station.

[0022] By adopting the above technical solution, the two jacking mechanisms can correspond to any two adjacent positioning columns, which means that no matter which positioning column the five-star foot is placed on the cooling table, the jacking mechanism can accurately drive. This design not only improves the flexibility and adaptability of the equipment, but also ensures the stability and accuracy of the five-star foot during taking, placing and cooling. By adding jacking mechanisms and evenly distributing positioning columns, the cooling equipment has been significantly improved in terms of automation, operation efficiency, stability and reliability. This design makes the cooling equipment better adapt to the needs of modern industrial production, improves production efficiency, reduces production cost, and provides more stable and reliable service for users.

[0023] In some embodiments, the number of positioning columns is n, and the cooling equipment further comprises n-2 air coolers. When the cooling table rotates and the two jacking mechanisms correspond to the two adjacent positioning columns, the other positioning columns correspond one-to-one to the air coolers.

[0024] By adopting the above technical solution, the number of positioning columns is set to n (n≥3), and these positioning columns are circumferentially distributed around the rotation center of the cooling table. The air coolers are installed at the bottom of the cooling table and correspond one-to-one to the positioning columns (except for the positioning columns corresponding to the two jacking mechanisms). When the cooling table rotates and the two jacking mechanisms correspond to the two adjacent positioning columns, the other positioning columns (i.e., the positioning columns without corresponding jacking mechanisms) will have air coolers below or near them to provide cold air. During the cooling process, the cooling table rotates at a set speed and direction. When the five-star foot is placed on the material placing station, it will pass through the position of each air cooler in turn as the cooling table rotates, and will be cooled by the cold air from the air coolers. Since the number and layout of the positioning columns and air coolers are carefully designed, the five-star foot can be evenly cooled during the cooling process.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. Compared with traditional cooling methods, this equipment can reduce the space required for cooling five-star feet, and the production site can be more compact and orderly arranged, which is conducive to lean management.

[0027] 2. It can speed up the production rhythm and improve the production efficiency, which is conducive to realizing automatic production.

[0028] 3. The cooling is more uniform, and the cooling efficiency is higher. BRIEF DESCRIPTION OF DRAWINGS

When the cooling table 1 rotates and the two lifting mechanisms 4 correspond to the positions of two adjacent positioning columns 6, the remaining positioning columns 6 correspond to the positions of the air coolers 9 one by one. This design can fully utilize space resources, improve cooling efficiency, and reduce energy consumption.

[0047] Two limit rods 7 are also fixedly provided on the cooling table 1. The two limit rods 7 are arranged on the outer periphery of the support plate 3.

The end of the positioning column 6 facing away from the cooling table 1 is sealed, while the end closest to the cooling table 1 is connected to the cooling holes on the cooling table 1, forming a cooling channel. The sidewall of the positioning column 6 is provided with multiple air outlet holes 61 extending through the sidewall to evenly distribute the cooling medium and improve cooling efficiency. The end of the positioning column 6 facing away from the cooling table 1 has a guide surface 62 to facilitate the smooth insertion of the five-star foot.

The cooling table 1 is also connected to a second drive element, such as an electric motor, to rotate the cooling table 1, facilitating automated production.

[0050] See also Figures 3-6The jacking mechanism 4 includes a push rod 44, two guide rods 42, a screw rod 43, the push rod 44, a bracket 45, a push plate 46, and a first driving member.

The cooling table 1 is provided with a through hole through which the push rod 44 passes and is connected with the stress surface 32, and the first driving member drives the push rod 44 to slide along the through hole to push the supporting plate 3 to slide. In the embodiment, the first driving member is a jacking motor 41, and a motor shaft of the jacking motor 41 is fixedly connected with the screw rod 43. The first driving member can also be a pneumatic cylinder or a hydraulic cylinder, or an electric push rod, and the specific selection depends on the production environment and equipment conditions. The push rod 44 can be made of steel or aluminum alloy to ensure its strength and durability. The structure design can accurately control the sliding distance and speed of the supporting plate 3, and improve the controllability and stability of the cooling process.

[0051] The positioning column 6 is provided with air outlet holes 61 on the side wall, and the end of the positioning column 6 away from the cooling table 1 is provided with a guide surface 62, which is convenient for the five-star foot to be put in.

[0052] The cooling equipment in the embodiment adopts a wind cooling system for cooling, which includes a cooling fan 9 and an air duct, is used for assisting the cooling liquid circulation system, and further improves the cooling efficiency.

[0053] Specifically, the cooling fan 9 can be a centrifugal fan or an axial flow fan, which is used for generating high-speed airflow and blowing cooling air to the five-star foot through the air outlet holes 61. The air duct can be made of aluminum or stainless steel, which is used for guiding the direction and speed of the cooling air. The wind cooling system can be combined with the cooling liquid circulation system to form a composite cooling system, which further improves the cooling efficiency.

[0054] The cooling equipment can also include a cooling liquid circulation system. The cooling system can adopt air cooling or water cooling. The water cooling circulation system includes a liquid storage tank, a pump, a filter, and a radiator, which are used for circulating and supplying cooling liquid, and further improve the cooling efficiency. By increasing the cooling liquid circulation system, the continuous supply and recycling of the cooling liquid can be realized, and the cooling efficiency of the five-star foot is further improved. The design of the cooling liquid circulation system can ensure the cleanliness and temperature stability of the cooling liquid, and avoid the decrease of the cooling effect caused by the pollution or temperature fluctuation of the cooling liquid. This design not only improves the cooling quality, but also effectively reduces the production cost, improves the production efficiency, and meets the demand of large-scale production.

[0055] By increasing the air cooling system, the cooling liquid circulation system and the air cooling system can be complementary, further improving the cooling efficiency of the five-star foot. The design of the air cooling system can ensure the uniform distribution and high-speed flow of the cooling air, effectively taking away the heat on the surface of the five-star foot and accelerating the cooling speed. This design not only improves the cooling quality, but also effectively deals with unexpected situations during production, improving the reliability and stability of production.

[0056] The working principle of this embodiment: the cooling equipment can realize efficient cooling of the five-star foot through the cooperation of the cooling table 1, the positioning column 6 and the jacking mechanism 4. When the cooling table 1 rotates, the two jacking mechanisms 4 correspond to the supporting plates 3 located at the material taking station 13 and the material placing station 12, and the jacking mechanisms 4 drive the supporting plates 3 to move up and down along the positioning columns 6. The positioning columns 6 of other stations correspond to the air coolers 9 under the cooling table 1, and the air coolers 9 blow cold air into the internal hollow cavities of the positioning columns 6 through the cooling holes of the cooling table 1, and the cold air flows out from the air outlets 61 to cool the five-star feet on the positioning columns 6. The cooling holes on the cooling table 1 and the cooling channels in the positioning columns 6 can guide the uniform distribution of the cooling medium and accelerate the cooling process of the five-star foot. The precise control of the jacking mechanism 4 can ensure the smooth sliding of the supporting plate 3 and avoid damage to the five-star foot during the cooling process. The placement sensor 2 and the material taking sensor 5 can monitor the state of the five-star foot in real time, ensuring the continuity and stability of the production process. This cooling equipment not only improves the cooling efficiency of the five-star foot, but also reduces production costs, improves production efficiency and meets the needs of modern furniture manufacturing.

[0057] Embodiment 2

[0058] The difference between this embodiment and embodiment one is that the cooling equipment also includes a monitoring system, which includes a camera and an image recognition module, for real-time monitoring of the five-star foot state during the cooling process to ensure the smooth progress of the cooling process. The camera can be installed above or beside the cooling table 1 to take real-time images of the five-star foot. The image recognition module can be a deep learning-based image recognition algorithm to analyze the state of the five-star foot and detect whether there are any abnormal conditions.

[0059] By increasing the monitoring system, the cooling efficiency of the five-star foot and the reliability of the production process can be further improved. The design of the monitoring system can monitor the state of the five-star foot in real time to ensure the smooth progress of the cooling process.

[0060] Embodiment 3

[0061] The difference between this embodiment and the above embodiments is that the cooling equipment also includes a temperature sensor and a controller, the temperature sensor is used to monitor the cooling temperature of the five-star foot in real time, and the controller adjusts the flow and temperature of the cooling medium according to the feedback signal of the temperature sensor to realize more precise temperature control.

[0062] Specifically, the temperature sensor can be a thermocouple or an infrared thermometer installed above or beside the cooling table 1 to monitor the temperature change of the five-star foot in real time. The controller can be a PLC (Programmable Logic Controller) or a single-chip microcomputer to receive the signal of the temperature sensor and control the flow and temperature of the cooling medium. The controller can automatically adjust the parameters of the cooling medium according to the preset temperature curve to ensure that the five-star foot is cooled within the optimal temperature range, improving the cooling quality and efficiency.

[0063] In addition, the cooling device also includes an alarm device that will issue an alarm when the cooling temperature of the five-star foot exceeds the preset safety range, reminding the operator to take timely measures to prevent the quality of the five-star foot from being affected by the temperature not meeting the cooling requirements.

[0064] By adding temperature sensors and controllers, precise control of the cooling process of the five-star foot can be achieved. Real-time monitoring by the temperature sensor and intelligent adjustment by the controller can ensure that the five-star foot remains within the optimal temperature range throughout the cooling process. This design not only improves the cooling quality, but also effectively prevents subsequent processing quality problems caused by temperature fluctuations, improving the reliability and stability of the production process. At the same time, the alarm device can timely alert potential risks to ensure production safety.
