Description

Technical Field

[0001] This utility model relates to the field of television back cover production, and in particular to a waste heat recovery device for injection molding machines in the processing of television back covers. Background Technology

[0002] Injection molding machines generate a large amount of waste heat during the processing of TV back covers. Directly discharging this waste heat leads to energy waste and increases production costs. By using technical means to recover and reuse the waste heat generated during the injection molding process, energy conservation, emission reduction, and cost reduction can be achieved. By turning on the exhaust fan, the waste heat generated by the injection molding machine is extracted through the exhaust pipe and transported to the engine through the air supply pipe. Recovering the waste heat into the engine can reduce energy consumption and increase engine output power. At the same time, it can reduce greenhouse gas emissions. When waste heat is generated, it is usually accompanied by heat loss. The original injection molding machine lacked insulation for waste heat, which resulted in a large loss of waste heat and limited waste heat recovery effect.

[0003] To address the aforementioned issues, a waste heat recovery device for injection molding machines used in the processing of television back covers has been developed. Utility Model Content

[0004] In order to overcome the shortcomings of the original injection molding machine for producing TV back covers, which lacks heat preservation, resulting in large heat loss and limited heat recovery effect, this utility model provides a heat recovery device for injection molding machine in TV back cover processing.

[0005] The technical solution of this utility model is as follows: A waste heat recovery device for an injection molding machine used in the processing of a TV back cover includes an injection molding machine. An exhaust fan is installed on the upper front side of the injection molding machine. An exhaust pipe is connected between the upper part of the injection molding machine and the upper part of the exhaust fan. An air supply pipe is connected between the right side of the injection molding machine and the right side of the exhaust fan. A waste heat insulation mechanism is installed on the upper part of the injection molding machine. The waste heat insulation mechanism includes a first mounting frame. The first mounting frame is connected to the upper part of the injection molding machine. A second mounting frame is rotatably connected to the rear side of the first mounting frame. A heat insulation layer is connected between the inner side of the second mounting frame and the injection molding machine.

[0006] As a preferred technical solution of this utility model, it also includes a filtering mechanism, which includes a connecting frame. The connecting frames are symmetrically installed at the front of the exhaust fan, and an mounting plate is snapped between the two connecting frames. A filter screen is installed on the mounting plate.

[0007] As a preferred embodiment of this utility model, the lower part of the exhaust fan has a hollow structure to facilitate heat dissipation.

[0008] In a preferred embodiment of this utility model, the second mounting frame is snapped into the front side of the first mounting frame.

[0009] As a preferred embodiment of this utility model, a handle is installed on the front side of the second mounting frame.

[0010] As a preferred embodiment of this utility model, the mounting plate is a detachable connection structure.

[0011] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0012] This invention features a waste heat insulation mechanism. The insulation layer wraps around the parts of the injection molding machine that generate waste heat, thereby reducing heat loss and improving the waste heat recovery effect. The snap-fit ​​connection between the first and second mounting frames at the front makes it easier to replace the insulation layer. To prevent impurities from being sucked into the exhaust fan inlet, this invention includes a filter mechanism. The filter screen filters out impurities, thus protecting the exhaust fan. When impurities accumulate on the filter screen, the mounting plate can be removed to clean the filter screen. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0019] A waste heat recovery device for injection molding machines used in the processing of television back covers, such as Figure 1 and Figure 2As shown, the system includes an injection molding machine 1, an exhaust fan 2 mounted on the upper front side of the injection molding machine 1, a hollow structure at the bottom of the exhaust fan 2 for easy heat dissipation, an exhaust pipe 3 connecting the upper part of the injection molding machine 1 and the upper part of the exhaust fan 2, an air supply pipe 4 connecting the right side of the injection molding machine 1 and the right side of the exhaust fan 2, a waste heat insulation mechanism 5 mounted on the upper part of the injection molding machine 1, the waste heat insulation mechanism 5 including a first mounting frame 51, the upper part of the injection molding machine 1 connected to the first mounting frame 51, a second mounting frame 52 rotatably connected to the rear side of the first mounting frame 51, the second mounting frame 52 engaging with the front side of the first mounting frame 51, a handle mounted on the front side of the second mounting frame 52, and a heat insulation layer 53 connecting the inner side of the second mounting frame 52 to the injection molding machine 1.

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a filter mechanism 6, which includes a connecting frame 61. The front of the exhaust fan 2 is equipped with symmetrical connecting frames 61. A mounting plate 62 is snapped between the two connecting frames 61. The mounting plate 62 is a detachable connection structure, and a filter screen 63 is installed on the mounting plate 62.

[0021] Injection molding machines generate a large amount of waste heat during the processing of television back covers. Directly discharging this waste heat leads to energy waste and increases production costs. By using technological means to recover and reuse the waste heat generated during the injection molding process, energy conservation, emission reduction, and cost reduction can be achieved. By turning on the exhaust fan 2, the waste heat generated by injection molding machine 1 is extracted through the exhaust pipe 3 and transported to the engine via the air supply pipe 4. Recovering the waste heat into the engine reduces energy consumption, thereby increasing engine output power and reducing greenhouse gas emissions. However, waste heat generation is usually accompanied by heat loss. The original injection molding machine 1 lacked insulation for waste heat, resulting in significant waste heat loss. The heat recovery effect is limited. The waste heat insulation mechanism 5 can reduce the dissipation of waste heat. The heat insulation layer 53 wraps the parts of the injection molding machine 1 that generate waste heat, thereby reducing heat loss. The connection method of the first mounting frame 51 and the second mounting frame 52 snapping together at the front makes it easier to replace the heat insulation layer 53. By using the handle to flip the second mounting frame 52 upward, the second mounting frame 52 is released from the snapping state with the first mounting frame 51, thereby quickly replacing the heat insulation layer 53. In order to prevent impurities from being sucked into the air inlet of the exhaust fan 2, the filter screen 63 filters the impurities, thereby protecting the exhaust fan 2. When impurities accumulate on the filter screen 63, the mounting plate 62 can be removed to clean the filter screen 63.

[0022] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
