Description

Technical Field

[0001] The utility model relates to the field of exhaust equipment, in particular to a hot air exhaust device for a die head of a casting machine. Background Art

[0002] The cast film machine is a device specially used for making cast film. It is widely used in many industries, such as flexible packaging film industry, medical protective materials, traditional packaging film, etc. The cast film machine needs to be heated at high temperature when it is started, so that the granules are melted at high temperature and then flow out from the die head to form the required product. Therefore, high-temperature hot air will be generated at the die head. The high-temperature hot air at the die head is easy to be retained in the workshop and cannot be discharged in time, which will cause the temperature of the workshop to gradually rise. The operating workers may be unable to bear the high temperature of the workshop, and the hot air generated will be accompanied by certain harmful components, affecting their health. Utility Model Content

[0003] In view of this, the utility model provides a hot gas discharge device for a die head of a casting machine which can effectively discharge high-temperature hot gas and purify the gas.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A hot air discharge device for a film casting machine die head comprises a frame, a die head arranged on the frame, and an exhaust mechanism located above the die head; the exhaust mechanism comprises an air collecting hood, an air suction box and a flexible air pipe connected in sequence, a support platform is provided at the top of the frame, the air collecting hood is slidably clamped on the support platform, a first opening connected to the air suction box is provided on the air collecting hood, a refrigeration plate is also provided in the air collecting hood, a second opening connected to the flexible air pipe is provided on the air suction box, and a filter element is provided at one end of the flexible air pipe close to the air suction box.

[0006] In the above technical solution, the hot air generated above the die head is directly captured by the setting of the gas collecting hood, and the efficient transmission of the air suction box and the flexible air pipe ensures that the hot air can be discharged quickly and effectively, effectively preventing the accumulation of hot air in the workshop, thereby optimizing the working environment. Secondly, the gas collecting hood is installed on the support table by sliding the card, making the use of the gas collecting hood more flexible. When the die head stops working, the gas collecting hood can be pushed into the support table to avoid contamination, reduce space occupation, and facilitate the maintenance of the die head.

[0007] In addition, the hood is equipped with a cooling plate, which can effectively reduce the temperature of the hot air entering the suction box, thereby further improving the efficiency of hot air discharge and reducing the burden on subsequent processing equipment. The filter element is designed to filter out dust and impurities in the hot air, improve gas quality, protect subsequent processing equipment from pollution, and extend the service life of the equipment.

[0008] Optionally, in a possible implementation, the air intake box includes a box body with a hollow interior, and a fan, the second opening is located at the top of the box body, and the fan is detachably fixed to the inner wall of the box body.

[0009] In the above technical solution, the detachable design of the fan allows it to be easily removed from the box when the fan fails or needs to be cleaned, without disassembling the entire suction box, thereby simplifying the maintenance process and improving work efficiency. In addition, the second opening is located at the top of the box, so that the airflow generated by the fan can be discharged smoothly, avoiding the accumulation of airflow in the box, and ensuring the air intake and exhaust effects of the equipment.

[0010] Optionally, in a possible implementation, a limiting ridge is provided on the top of the box body, and the limiting ridge is arranged around the second opening. The filter element is detachably arranged in the limiting ridge and covers the second opening.

[0011] In the above technical solution, by providing a limiting flange surrounding the second opening, the filter element can be accurately aligned and placed in the flange, thereby ensuring accurate installation of the filter element. And because the filter element is detachable, when the filter element needs to be replaced or cleaned, it can be easily taken out of the flange and replaced. Secondly, the close fit between the limiting flange and the filter element ensures good sealing of the second opening, which can prevent air from leaking between the filter element and the box body, thereby improving the filtering effect and performance of the air intake box.

[0012] Optionally, in a possible implementation manner, a first threading hole is provided on the box body, and the first threading hole is close to the fan.

[0013] In the above technical solution, the setting of the first wire threading hole can provide a certain convenience for the wiring of the fan wires. Since the fan usually needs to be connected to a power cord or other control wires, the wire threading holes close to the fan allow these wires to pass through the box directly and smoothly, avoiding the wires from being too long or bending, reducing the risk of wire damage, and also improving the overall aesthetics.

[0014] Optionally, in a possible implementation manner, a second threading hole is provided on the air collecting hood, and the second threading hole is close to the refrigeration plate.

[0015] Similarly, the provision of the second wire threading hole can provide a certain convenience for the wiring of the refrigeration panel wires, allowing the wires to pass through the gas collecting hood directly and smoothly, avoiding the wires from being too long or bending, reducing the risk of wire damage, and improving the overall aesthetics.

[0016] Optionally, in a possible implementation, an extension plate is further provided on the air collecting hood, a guide rail is provided on the support platform, one end of the extension plate is connected to the side wall of the air collecting hood, and the other end is slidably clamped on the guide rail.

[0017] In the above technical solution, an extension plate is arranged on the air collecting hood and a guide rail is provided on the support platform so that the extension plate can be slid and adjusted along the guide rail, thereby enhancing the flexibility and adjustability of the use of the air collecting hood. At the same time, the guide rail can also support the extension plate to prevent the air collecting hood from being offset or tilted, thereby ensuring that the air collecting hood can effectively exert its effect.

[0018] Optionally, in a possible implementation, the extension plate is an “L”-shaped structure.

[0019] In the above technical solution, the "L"-shaped extension plate can facilitate the connection between the air hood and the guide rail, that is, the extension plate, as a part of the air hood, can facilitate the air hood to slide along the guide rail, and can also provide additional support or coverage area for the air hood in the horizontal and vertical directions.

[0020] Optionally, in a possible implementation manner, the extension plate and the guide rail are two groups symmetrically arranged on opposite sides of the air collecting hood.

[0021] In the above technical solution, since the extension plate and the guide rail are symmetrically arranged on both sides of the air collecting hood, it can ensure that the air collecting hood remains balanced during use, thereby avoiding tilting or shaking, and can also increase the support area of ​​the air collecting hood, making it more stable during movement or use.

[0022] Optionally, in a possible implementation manner, one end of the flexible air pipe away from the air suction box is further connected to an exhaust pipe.

[0023] In the above technical solution, by connecting the exhaust pipe, the flexible air pipe can more effectively discharge the gas in the air intake box, thereby ensuring the smoothness of the exhaust process. Since the flexible air pipe has good flexibility, after connecting the exhaust pipe, the entire exhaust system can be arranged and installed more flexibly.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] The hot air discharge device of the utility model collects the hot air above the die head through the air collecting hood, and cooperates with the efficient transmission of the air suction box and the flexible air pipe to ensure that the hot air is discharged quickly and effectively. The setting of the refrigeration plate and the filter element can reduce the gas temperature and improve the gas quality. Therefore, the device effectively reduces the heat accumulation and air pollution in the workshop, is more environmentally friendly and energy-saving, optimizes the working environment, and protects the health of the operators.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0033] Please refer to Figure 1The present embodiment provides a hot air discharge device for a casting machine die head 2, comprising a frame 1, a die head 2 arranged on the frame 1, and an exhaust mechanism 3 located above the die head 2; the exhaust mechanism 3 comprises an air collecting hood 31, an air suction box 32 and a flexible air pipe 33 connected in sequence, the air collecting hood 31, the air suction box 32 and the flexible air pipe 33 are connected in sequence, a support platform 11 is provided at the top of the frame 1, the air collecting hood 31 is slidably mounted on the support platform 11 and can slide to the top of the die head 2, a first opening 311 connected to the air suction box 32 is provided on the air collecting hood 31, and a refrigeration plate 34 is also provided in the air collecting hood 31, a second opening 3211 connected to the flexible air pipe 33 is provided on the air suction box 32, and a filter element 35 is provided at one end of the flexible air pipe 33 close to the air suction box 32.

[0034] This embodiment directly captures the hot air generated above the die head 2 by setting up the gas collecting hood 31, and cooperates with the efficient transmission of the air suction box 32 and the flexible air pipe 33 to ensure that the hot air can be discharged quickly and effectively, effectively preventing the accumulation of hot air in the workshop, thereby optimizing the working environment. Secondly, the gas collecting hood 31 is installed on the support platform 11 by sliding the card, making the use of the gas collecting hood 31 more flexible. When the die head 2 stops working, the gas collecting hood 31 can be pushed into the support platform 11, which can avoid contamination, reduce space occupation, and facilitate the maintenance of the die head 2.

[0035] In addition, a cooling plate 34 is provided in the air collecting hood 31, which can effectively reduce the temperature of the hot air entering the air suction box 32, thereby further improving the efficiency of hot air discharge and reducing the burden on subsequent processing equipment. The filter element 35 is designed to filter out dust and impurities in the hot air, improve gas quality, protect subsequent processing equipment from pollution, and extend the service life of the equipment.

[0036] In this embodiment, the air suction box 32 includes a hollow box body 321 and a fan 322. The second opening 3211 is located at the top of the box body 321, and the fan 322 is detachably fixed to the inner wall of the box body 321. The box bottom is a bottom opening structure, and the fan 322 is placed between the second opening 3211 and the bottom opening. The bottom opening is the direction of air suction, that is, the gas is sucked from the bottom opening of the box bottom to the second opening 3211, and the bottom and top of the box body 321 are respectively connected to the air collecting hood 31 and the flexible air pipe 33.

[0037] The detachable design of the fan 322 allows it to be easily removed from the box 321 when the fan 322 fails or needs to be cleaned, without having to disassemble the entire suction box 32, thereby simplifying the maintenance process and improving work efficiency. In addition, the second opening 3211 is located at the top of the box 321, so that the airflow generated by the fan 322 can be discharged smoothly, avoiding the accumulation of airflow in the box 321, and ensuring the suction and exhaust effects of the equipment.

[0038] In this embodiment, a limiting convex edge 3736 is provided on the top of the box body 321, and the limiting convex edge 3736 is arranged around the second opening 3211. The filter element 35 is detachably arranged in the limiting convex edge 3736 and covers the second opening 3211. The limiting convex edge 3736 is an annular cylindrical structure. Taking a cylinder as an example, the second opening 3211 can be set to a circular shape. The diameter of the limiting convex edge 3736 is greater than the diameter of the second opening 3211. Therefore, the limiting convex edge 3736 and the edge of the second opening 3211 will form a step-like structure, and the filter element 35 can be placed at the step-like structure.

[0039] Therefore, by providing the limiting flange 3736 surrounding the second opening 3211, the filter element 35 can be accurately aligned and placed in the flange, thereby ensuring the accurate installation of the filter element 35. And because the filter element 35 is detachable, when the filter element 35 needs to be replaced or cleaned, it can be easily taken out from the flange and replaced. Secondly, the tight fit between the limiting flange 3736 and the filter element 35 ensures good sealing of the second opening 3211, which can prevent air from leaking between the filter element 35 and the box body 321, thereby improving the filtering effect and performance of the suction box 32.

[0040] In this embodiment, the box body 321 is provided with a first threading hole 3212, and the first threading hole 3212 is close to the fan 322. The provision of the first threading hole 3212 can provide a certain convenience for wiring the wires of the fan 322. Since the fan 322 usually needs to be connected to a power line or other control lines, the threading hole close to the fan 322 allows these wires to pass through the box body 321 directly and smoothly, avoiding excessive length or bending of the wires, reducing the risk of wire damage, and also improving the overall aesthetics.

[0041] Similarly, the air collecting cover 31 is provided with a second threading hole 312, and the second threading hole 312 is close to the refrigeration plate 34. The second threading hole 312 can provide a certain convenience for the wiring of the wires of the refrigeration plate 34, so that the wires can pass through the air collecting cover 31 directly and smoothly, avoiding the excessive length or bending of the wires, reducing the risk of wire damage, and improving the overall aesthetics.

[0042] In this embodiment, an extension plate is further provided on the air collecting hood 31, and a guide rail 12 is provided on the support platform 11. One end of the extension plate is connected to the side wall of the air collecting hood 31, and the other end is slidably clamped on the guide rail 12. Among them, the extension plate is an "L"-shaped structure. The connection between the extension plate and the guide rail 12 can be an "I"-shaped connection, that is, the guide rail 12 is an "I"-shaped structure, and the extension plate is a corresponding "I"-shaped groove structure, which has the advantage that the sliding direction between the extension plate and the guide rail 12 can be limited, and at the same time it also has good support.

[0043] In this embodiment, an extension plate is provided on the air collecting hood 31, and a guide rail 12 is equipped on the support platform 11, so that the extension plate can be slid and adjusted along the guide rail 12, thereby enhancing the flexibility and adjustability of the use of the air collecting hood 31. At the same time, the guide rail 12 can also support the extension plate to prevent the air collecting hood 31 from being offset or tilted, thereby ensuring that the air collecting hood 31 can effectively exert its effect.

[0044] In addition, the "L"-shaped extension plate can facilitate the connection between the air hood 31 and the guide rail 12, that is, the extension plate, as a part of the air hood 31, can facilitate the air hood 31 to slide along the guide rail 12, and can also provide additional support or coverage area for the air hood 31 in the horizontal and vertical directions.

[0045] In this embodiment, the extension plate and the guide rail 12 are symmetrically arranged in two groups on opposite sides of the air collecting hood 31, and the two guide rails 12 are parallel to each other. Since the extension plate and the guide rail 12 are symmetrically arranged on both sides of the air collecting hood 31, it can ensure that the air collecting hood 31 remains balanced during use, thereby avoiding tilting or shaking, and can also increase the support area of ​​the air collecting hood 31, making it more stable during movement or use.

[0046] It should be noted that the end of the flexible air pipe 33 of this embodiment away from the air suction box 32 is also connected to an exhaust pipe 38. By connecting to the exhaust pipe 38, the flexible air pipe 33 can more effectively discharge the gas in the air suction box 32, thereby ensuring the smoothness of the exhaust process, and because the flexible air pipe 33 has good flexibility, after connecting to the exhaust pipe 38, the entire exhaust system can be arranged and installed more flexibly.
