Description

Technical Field

[0001] This utility model relates to the field of door and window manufacturing equipment technology, and in particular to a cooling device for door and window manufacturing. Background Technology

[0002] In modern door and window manufacturing, metal or plastic door and window profiles typically undergo high-temperature processing steps such as extrusion and welding. To ensure the dimensional stability and mechanical properties of the profiles after forming, rapid and effective cooling is essential. Currently, the commonly used method is to spray or immerse the high-temperature profiles in water to achieve rapid cooling.

[0003] However, water-cooled window and door profiles will have a lot of moisture adhering to their surfaces. If natural air drying is relied upon, not only will the drying speed be slow and occupy a lot of production space, seriously affecting production efficiency, but for metal profiles, prolonged dampness will also cause surface oxidation or corrosion, forming water stains or rust spots. This not only affects the appearance of the product, but also negatively impacts the adhesion of subsequent surface treatment processes such as spraying and coating.

[0004] To address these issues, some existing production lines add a separate drying process after the cooling step. However, this typically means manually handling the wet profiles from the cooling area or transferring them to the drying equipment via a separate conveyor system. This separate operation disrupts the continuity of the production process, increases additional labor costs and material transfer time, and the profiles are more prone to physical damage such as bumps and scratches during multiple handling processes, thus reducing the final product's pass rate. The entire process is cumbersome, has low automation, and is difficult to improve overall efficiency.

[0005] Therefore, this utility model proposes a cooling device for door and window manufacturing to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the cooling device for door and window manufacturing, such as the separation of door and window profile cooling and drying processes, low degree of automation, and easy damage to profiles during the transfer process, this utility model aims to provide a cooling device for door and window manufacturing with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a cooling device for door and window manufacturing, including a box, a conveying mechanism and a cooling mechanism disposed inside the box, and a control panel disposed on the outer wall of the box.

[0008] The cooling mechanism includes a cooling tank and a drying tank arranged sequentially along the moving path of the conveying mechanism. A nozzle is fixedly connected to the top of the cooling tank, and a second nozzle is also installed inside the cooling tank. The profile is rapidly and uniformly cooled in three dimensions by spraying water from both above and below. The cooling tank and the drying tank are physically separated by a baffle plate, which effectively isolates the dry and wet areas.

[0009] The conveying mechanism includes a slide rail fixedly connected to the inner wall of the box and a drain rack that can move on the slide rail. The drain rack is slidably connected to the slide rail through a sliding strip on its outer wall, forming a stable guiding and bearing system.

[0010] The control panel controls the conveyor mechanism via electrical connection, enabling the drain rack to move automatically back and forth between the cooling tank and the drying tank, seamlessly connecting the cooling and drying processes.

[0011] Preferably, the inside of the drain rack is provided with a placement net for supporting door and window profiles; in order to improve the stability of the transfer process, multiple shock-absorbing blocks made of elastic rubber are fixedly connected between the two sides of the placement net and the inner wall of the drain rack to absorb vibration and impact and protect the surface of the profiles from damage.

[0012] Preferably, a dryer is fixedly connected above the drying trough, with the air outlet of the dryer facing the inside of the drying trough, which can blow hot air to quickly and forcefully dry the door and window profiles in the area, effectively preventing rust.

[0013] Preferably, the cooling device further includes a coolant circulation system; the system includes a coolant storage tank located at the bottom of the tank and a drain pipe connecting the bottom of the cooling tank to the coolant storage tank for centralized recycling of used coolant.

[0014] Preferably, the coolant circulation system further includes a water outlet pipe connecting the coolant storage tank to spray head one and spray head two; in order to realize the power delivery and temperature control of the coolant, a water pump and a chiller are installed in series on the water outlet pipe to ensure the effect of spray cooling.

[0015] Preferably, in order to ensure the cleanliness of the circulating coolant, a filter screen is installed near the inlet of the coolant storage tank; the end of the drain pipe is located above the filter screen, so that the recovered coolant can be effectively filtered out of impurities before entering the storage tank.

[0016] Preferably, the box body has an inlet and an outlet for the drain rack to enter and exit on opposite sides; in order to support the movement of the drain rack outside the box body, a bracket is fixedly connected to the outside of the box body at the positions corresponding to the inlet and outlet respectively, and a slide rail extends from the inside of the box body to the bracket.

[0017] Preferably, in order to facilitate operators to monitor the working status inside the enclosure in real time, an observation window is also provided on the side wall of the enclosure. The observation window is inlaid with a transparent sealing plate, which allows for clear observation without affecting the overall sealing of the equipment.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problems of dispersed processing procedures, low automation, and low production efficiency of door and window profiles in the prior art by setting up a conveying mechanism that can automatically transfer door and window profiles between the cooling mechanism and the drying mechanism, and integrates the cooling and drying processes into one, thus achieving the technical effect of automated continuous production and significantly improving processing efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figures 1 to 4 This utility model provides a cooling device for door and window manufacturing, which aims to solve the problems of separation of door and window profile cooling and drying processes, low degree of automation and poor transfer stability in the prior art.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a cooling device for door and window manufacturing has an overall structure that mainly includes a box 1 as the main body for installation, a cooling mechanism 2 and a conveying mechanism 3 disposed inside the box 1, and a control panel 7 fixedly connected to the outer wall of the box 1. Specifically, the cooling mechanism 2 is used to cool and dry the door and window profiles. It includes a cooling tank 201 and a drying tank 211 arranged sequentially along the moving path of the conveying mechanism 3. The cooling tank 201 and the drying tank 211 are physically separated by a fixedly connected baffle plate 210. The baffle plate 210 can effectively prevent the coolant in the cooling tank 201 from splashing into the drying tank 211. The conveying mechanism 3 is used to carry door and window profiles and complete automated transfer inside the box 1. The conveying mechanism 3 includes a slide rail 302 fixedly connected to the inner wall of the box 1, and a drain rack 303 that can reciprocate along the slide rail 302. A sliding strip 304 that slides with the slide rail 302 is fixedly connected to the outer wall of the drain rack 303. Through the sliding connection structure between the sliding strip 304 and the slide rail 302, the drain rack 303 can move smoothly inside the box 1. The control panel 7 is electrically connected to the drive motor of the conveying mechanism 3 to precisely control the operation of the conveying mechanism 3, so that the drain rack 303 can perform programmed reciprocating motion along the slide rail 302 between the cooling tank 201 and the drying tank 211, thereby realizing the automatic transfer of door and window profiles between the cooling and drying stations. In order to achieve efficient cooling, a nozzle 202 is fixedly connected to the top of the cooling tank 201, and a nozzle 203 is also provided inside the tank of the cooling tank 201. The combination of nozzle 202 and nozzle 203 can provide three-dimensional spray cooling to the door and window profiles located on the drain rack 303 from multiple directions.

[0026] Please refer to Figure 4 The interior of the drain rack 303 is equipped with a placement net 305 for directly supporting door and window profiles. The mesh structure of the placement net 305 facilitates the rapid dripping of coolant. Between the two sides of the placement net 305 and the inner wall of the drain rack 303, multiple shock-absorbing blocks 306 are fixedly connected by adhesive or snap-fit. The shock-absorbing blocks 306 are made of elastic rubber and their function is to absorb the vibration and impact generated by the drain rack 303 during start-up, stop or movement by using their own elastic deformation, thereby preventing the door and window profiles placed on the placement net 305 from shaking, bumping or scratching. The drain rack 303 forms a stable sliding fit with the slide rail 302 fixedly connected to the inner wall of the box 1 through the sliding strip 304 fixedly connected to its outer wall. This fit structure provides precise guidance and limit for the reciprocating motion of the drain rack 303. This design, which combines a stable load-bearing net 305, a shock-absorbing block 306, a precisely positioned slide rail 302, and a sliding strip 304, ensures the high stability and safety of door and window profiles throughout the automated transfer process, effectively balancing transfer efficiency and profile protection.

[0027] In a preferred embodiment, in order to achieve thorough drying of the door and window profiles, a dryer 212 is fixedly connected above the drying trough 211. The air outlet of the dryer 212 faces the inside of the drying trough 211, and the door and window profiles located in the drying trough 211 are quickly dried by blowing out hot air.

[0028] In a preferred embodiment, in order to achieve the recycling of coolant, the cooling device also includes a coolant circulation system. The coolant circulation system includes a coolant storage tank 205 located at the bottom of the housing 1, and a drain pipe 204 connecting the bottom of the cooling tank 201 to the coolant storage tank 205. Used coolant flows back to the coolant storage tank 205 through the drain pipe 204.

[0029] Based on the above-mentioned coolant circulation system, in order to deliver the coolant to the spray position, the system also includes a water outlet pipe 208 connecting the coolant storage tank 205 with the first spray nozzle 202 and the second spray nozzle 203. A water pump 209 for providing delivery power and a cooler 207 for reducing the temperature of the coolant are installed in series on the water outlet pipe 208.

[0030] Furthermore, in order to purify the recovered coolant, a filter screen 206 is installed near the inlet of the coolant storage tank 205, and the end of the drain pipe 204 is located above the filter screen 206. This arrangement allows the recovered coolant to be effectively filtered of impurities by the filter screen 206 before entering the coolant storage tank 205.

[0031] In a preferred embodiment, to facilitate the entry and exit of door and window profiles, an inlet 4 and an outlet 5 are respectively provided on opposite sides of the box 1 for the drain rack 303 to enter and exit. A bracket 301 is fixedly connected to the outside of the box 1 at the positions corresponding to the inlet 4 and the outlet 5 respectively. A slide rail 302 extends from the inside of the box 1 to the bracket 301 to support the movement of the drain rack 303 outside the box 1.

[0032] As a preferred embodiment, in order to facilitate operators to monitor the situation inside the box 1 in real time, an observation window 6 is also provided on the side wall of the box 1, and a transparent sealing plate is embedded in the observation window 6.

[0033] Working principle: First, the door and window profiles that need to be cooled are placed in the drain rack 303 of the conveying mechanism 3, which is stopped at the feed inlet 4, and are stably supported by the placement net 305. Then, the working program is started through the control panel 7. The control panel 7 controls the operation of the conveying mechanism 3. Under the guidance of the sliding strip 304 on the outer wall and the slide rail 302 on the inner wall of the box 1, the drain rack 303 is stably moved into the inside of the box 1 and is precisely positioned above the cooling tank 201. When the drain rack 303 reaches the cooling position, the control panel 7 instructs the cooling mechanism 2 to start working, and the water pump 209 starts to pump the low-temperature coolant in the coolant storage tank 205, which has been cooled by the refrigerator 207, through the water outlet pipe 208 to the nozzle 1 202 and nozzle 2 203. The nozzle 1 202 sprays the door and window profiles from top to bottom and the nozzle 2 203 sprays from bottom to top at the same time, achieving rapid and uniform cooling. During this process, the shock-absorbing block 306 can absorb the impact of the spray and keep the profile stable. During the cooling process, the used coolant will drip through the placement net 305 to the bottom of the cooling tank 201, and then flow back through the drain pipe 204. Before entering the coolant storage tank 205, the returned coolant will be filtered through the filter net 206 to remove impurities and then cooled again by the cooler 207, thereby achieving clean recycling of the coolant. The whole process can be monitored in real time through the observation window 6 on the side wall of the tank 1. After cooling is complete, the control panel 7 controls the drain rack 303 to continue moving along the slide rail 302, passing the baffle plate 210 and entering the top of the drying tank 211. At this time, the dryer 212 starts to dry the door and window profiles with hot air, thoroughly removing the residual coolant on the surface and preventing rust. Finally, the drain rack 303 transports the processed door and window profiles to the discharge port 5, and the entire automated cooling and drying process ends.
