Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating technology, and in particular to a strong cooling mechanism for a coating line. Background Technology
[0002] In a coating production line, after the workpiece has been sprayed and baked, it must undergo a forced cooling process to rapidly and evenly reduce it to room temperature to meet the requirements of subsequent processes. The efficiency, energy consumption, and adaptability of the forced cooling process to different workpieces directly affect the overall production efficiency, operating costs, and product quality of the entire production line.
[0003] A search revealed patent CN222739602U, which discloses a forced cooling chamber for a non-standard parts coating line, relating to the field of coating line processing technology. This forced cooling chamber includes an operating box, a placement mechanism, and a driving mechanism. The placement mechanism includes a support component and a connecting component disposed within the operating box. The connecting component connects the support component and the operating box. The support component has a perforated plate. The driving mechanism includes a U-shaped connecting frame on the support component and a gear within the U-shaped connecting frame. This device, through the support component, ensures that parts placed on the perforated plate can move horizontally without contacting the inner wall of the operating box. This design eliminates the need for manual handling of the forced-cooling parts, reducing the workload of workers and preventing damage to the forced-cooling equipment due to collisions between parts and the equipment during handling. This plays a crucial protective role in ensuring the normal operation of the device.
[0004] While the above solution achieves a certain degree of automation in material handling and avoids manual processing, it still has the following significant drawbacks, making it difficult to meet the demands of modern flexible, high-efficiency, and energy-saving production:
[0005] 1. Integral structure, poor flexibility and high energy consumption: This equipment is a single, integrated cooling chamber. Regardless of the number of workpieces requiring cooling, air must be supplied to the entire chamber for cooling whenever the equipment is started. This "all-on" mode cannot be adjusted according to the actual production load, resulting in huge energy waste and high operating costs when only a small number of workpieces need to be processed.
[0006] 2. Inability to achieve parallel processing and flexible production: It has only one effective workstation, allowing it to process only one type of workpiece at a time, and the cooling parameters cannot be differentiated according to workpiece characteristics. This makes it extremely unsuitable for scenarios requiring the simultaneous cooling of multiple different types of workpieces with varying cooling process requirements, severely limiting the flexibility of production scheduling.
[0007] 3. Lack of consideration for airflow connection and sealing: While this solution primarily addresses the issue of automatic workpiece transfer, it lacks detailed and optimized design regarding how to efficiently and securely deliver cooling air into the unit carrying the workpiece. The cold air may blow directly into the entire enclosure rather than being concentrated and directed at the workpiece, resulting in relatively low cooling efficiency and potential energy loss due to poor sealing.
[0008] Therefore, in order to solve the aforementioned problems, we propose a strong cooling mechanism for coating lines. Utility Model Content
[0009] The purpose of this invention is to address the deficiencies in the existing technology by proposing a strong cooling mechanism for a coating line.

[0015] Furthermore, a solenoid valve is fixedly installed inside the gas pipeline, and both the solenoid valve and the electromagnet are electrically connected to the controller.
[0016] Furthermore, multiple infrared sensors are fixedly installed at equal intervals from top to bottom on the rear side inside the housing.

[0018] Furthermore, a door is movably installed on the front of the cooling box, and the door is fixed by a latch. Handles are fixedly installed on both the left and right sides of the front of the door.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0028] Reference Figure 1-4A strong cooling mechanism for a painting line includes a housing 1. An air supply mechanism 2 is fixedly installed on the top of the housing 1, and an air supply channel 3 is fixedly installed on the back of the housing 1. The air supply mechanism 2 is connected to the air supply channel 3. Multiple output pipes are fixedly installed at equal intervals from top to bottom on the rear side inside the housing 1, and all of the multiple output pipes are connected to the air supply channel 3. Multiple cooling boxes 5 are slidably installed from top to bottom inside the housing 1. Connecting pipes are fixedly installed on the rear side of each of the multiple cooling boxes 5, and the multiple cooling boxes 5 are connected to the corresponding output pipes through the connecting pipes. A controller 8 is fixedly installed on one side of the housing 1, and the air supply mechanism 2 is electrically connected to the controller 8.
[0029] The air supply mechanism 2 delivers cold air into the cooling box 5 through the air supply pipe 3, output pipe, and connecting pipe. The cooling box 5 can store the workpieces that need to be cooled, thereby achieving the cooling of the workpieces. The air supply mechanism 2 is an existing electrical component and can be selected according to actual needs.
[0030] The output pipeline includes a gas supply pipe 11, with an electromagnet 12 fixedly installed at the front end of the gas supply pipe 11. The connecting pipeline includes a connecting pipe 13, with an iron ring 14 fixedly installed at the rear end of the connecting pipe 13, and a sealing ring fixedly installed on the rear side of the iron ring 14. A solenoid valve is fixedly installed inside the gas supply pipe 11, and both the solenoid valve and the electromagnet 12 are electrically connected to the controller 8.
[0031] The electromagnet at the front end of the gas pipe 11 and the iron ring at the rear end of the connecting pipe 13 form an automatic docking mechanism. When the cooling box 5 is pushed into place, the controller 8 controls the electromagnet 12 to be energized to generate magnetic force, which pulls the iron ring 14 and the entire cooling box 5 backward, so that the sealing ring is tightly pressed onto the interface end face of the gas pipe 11, achieving a reliable seal and realizing the quick assembly and disassembly effect of "push in and it's in, disconnect when the power is off".
[0032] Multiple infrared sensors are fixedly installed at equal intervals from top to bottom on the rear side inside the housing 1. The multiple infrared sensors are spaced apart from multiple output pipelines, and all multiple infrared sensors are electrically connected to the controller 8.
[0033] Each output pipeline has an independent solenoid valve and a corresponding infrared sensor, enabling the controller 8 to detect the presence of a cooling box 5 at each workstation. The controller 5 can then independently control the airflow cooling to each cooling box 5 according to the production cycle. This achieves the following effects:
[0034] 1. It can operate at non-full load, cooling only the cooling box 5 containing the workpiece, which is energy-saving and efficient.
[0035] 2. The cooling parameters of each cooling box 5, such as cooling time and air volume, can be set independently to meet the cooling needs of different workpieces.
[0036] 3. It achieves a high degree of modularity, and the number of cooling boxes 5 can be flexibly adjusted according to production needs.
[0037] Multiple protruding strips 4 are fixedly installed at equal intervals from top to bottom on both the left and right sides inside the housing 1. Grooves 10 that match the protruding strips 4 are opened on both the left and right sides of the cooling box 5. The cooling box 5 is slidably installed inside the housing 1 through the grooves 10 and the protruding strips 4. Exhaust grooves 9 are opened inside the multiple protruding strips 4 and the grooves 10.
[0038] The sliding fit between the protruding strip 4 and the groove 10 not only provides guidance, but the internal venting groove 9 can balance the pressure and orderly discharge gas that may leak into the gap between the side wall of the housing 1 and the cooling box 5 during the cooling process, preventing pressure buildup from affecting the smooth sliding of the cooling box. It also has a heat dissipation and dehumidification function, discharging hot and humid air, helping to reduce the overall internal temperature of the housing 1, preventing steam condensation on the guide rails that could cause corrosion or freezing, and ensuring reliable long-term operation.
[0039] A door 6 is movably installed on the front of the cooling box 5. The door 6 is fixed by a latch, and handles 7 are fixedly installed on both the left and right sides of the front of the door 6.
[0040] The handle 7 and latch on the door 6 allow operators to safely open and close the cooling box 5 and to pick up and put away workpieces.
[0041] Working principle:
[0042] First, the operator opens the door 6 of an empty cooling box 5 using handle 7, places the workpiece that has been painted and requires intensive cooling into the cooling box 5, and closes and locks the door 6. Then, the cooling box 5 is pushed into the predetermined depth along the ridge 4 inside the box body 1. When the cooling box 5 moves to the correct position, its rear connecting pipe 13 aligns with the corresponding air supply pipe 11 on the rear air supply channel 3.
[0043] Subsequently, the infrared sensor fixedly installed on the rear side of the housing 1, corresponding to the workstation, detects that the cooling box 5 has arrived and transmits a signal to the controller 8. The controller 8 then issues a command to energize the electromagnet 12 at the front end of the air supply pipe 11 at this workstation, generating a strong magnetic field. The magnetic force generated by the electromagnet 12 attracts the iron ring 14 fixed to the rear end of the connecting pipe 13, thereby slightly pulling the entire cooling box 5 backward, causing the sealing ring on the front side of the iron ring 14 to be tightly pressed against the end face of the air supply pipe 11, forming a sealed connection channel. At the same time, the controller 8 keeps the solenoid valve of this pipeline closed, waiting for the cooling command.
[0044] When the system needs to begin cooling operations, the controller 8 activates the air supply mechanism 2. Cool air is delivered to each output pipe via the air supply channel 3. At this time, the controller 8 only sends an opening command to the solenoid valve corresponding to the workstation where the cooling box 5 has been detected and the sealing connection has been completed. The clean cool air then passes through the opened solenoid valve, through the air supply pipe 11 and the connecting pipe 13, and finally enters the designated cooling box 5 to provide uniform and efficient forced cooling to the workpiece.
[0045] During the cooling process, a small amount of gas may escape from the gaps in the cooling box 5 or due to minor leaks in the sealing ring, entering the gap between the inner wall of the box 1 and the outer wall of the cooling box 5. This gas can be orderly discharged to the outside of the box 1 through the exhaust grooves 9 opened inside the protrusions 4 and the grooves 10, which can effectively prevent abnormal pressure rise inside the box 1, ensure smooth sliding of the cooling box 5, and also facilitate heat dissipation and moisture prevention.
[0046] After the preset cooling time or temperature is reached, the controller 8 closes the solenoid valve on the air supply pipe 11 of that station, stopping the air supply. Then, the controller 8 cuts off the power to the electromagnet 12, the magnetic force disappears, and the sealed connection between the cooling box 5 and its corresponding air supply pipe 11 is released. The operator can then easily pull the cooling box 5 out of the box body 1, open the box door 6, and take out the cooled workpiece.
