Description

Technical Field

[0001] This utility model relates to the technical field of biodegradable membrane production equipment, and in particular to a biodegradable membrane heating device. Background Technology

[0002] In the production of biodegradable films, after the molten polymer is extruded from the extruder die, it usually needs to be pre-shaped by calendering rollers. After passing through multiple sets of calendering rollers, the film's temperature will be lower than its glass transition temperature or softening point, which can lead to problems such as insufficient material ductility, unevenness, and easy breakage in subsequent stretching processes. Therefore, the film is usually heated a second time between the calendering and stretching processes. In some cases, due to the large number of calendering roller sets, the long calendering path, and changes in ambient temperature, it is sometimes necessary to add heating devices to certain parts of the production line to better control the film temperature before stretching. However, current heating devices are difficult to install quickly, and modifying the production line would lead to prolonged downtime and seriously affect the production schedule.

[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] refer to Figure 1-7 An exemplary embodiment illustrates a biodegradable membrane heating device, including a base 1, a mounting frame 2, a heating component 3, and a shielding component 4; the mounting frame 2 is vertically and flexibly mounted on the base 1; the heating component 3 includes a housing 31 and a heating element 32 disposed within the housing 31, the housing 31 being dampedly hinged to the mounting frame 2 about a horizontal axis, and the housing 31 having an opening 311 for the heating element 32 to output energy; the shielding component 4 is disposed at the opening 311 of the housing 31 to control the size of the cross-sectional area through which energy can pass through the opening 311.

[0037] The heating device features a convenient overall structure for easy transport and rapid transfer, enabling quick installation and disassembly on the production line. When a heating device needs to be added, it can be quickly placed in a suitable location without requiring large-scale modifications to the production line, minimizing disruption to normal production. The mounting frame 2 is height-adjustable on the base 1, allowing for flexible adjustment of the heating component 3's height based on the actual position and height of the film on the production line. The housing 31 of the heating component 3 is damped and hinged to the mounting frame 2 around a horizontal axis, allowing the housing 31 to rotate freely within a certain angle range and stably remain in the desired position. The angle of the housing 31 can be flexibly adjusted according to the film's orientation, thereby changing the direction of energy output from the heating element 32, allowing for more precise application of heating energy to the film. The shielding component 4 is located at the opening 311 of the housing 31. By controlling the cross-sectional area through which energy can pass through the opening 311, the energy output from the heating element 32 to the film can be easily adjusted. This ensures the film reaches the appropriate temperature before stretching while preventing excessive energy output and overheating damage.

[0038] Among these, the energy, as mentioned above, includes heat, thermal radiation (such as infrared radiation), etc.

[0039] like Figure 6 and Figure 7As shown, the height and pitch angle of the heating component 3 can be adjusted according to the direction, height, and position of the film at the location where the heating device is installed. Specifically, by moving the position of the heating device and adjusting the height of the heating component 3, the distance between the heating component 3 and the film can be adjusted, thus roughly adjusting the amount of energy output from the heating component 3 to the film; while the shielding component 4 can more precisely adjust the amount of energy output from the heating component 3 to the film.

[0040] In this embodiment, the heating element 32 is an infrared heater. The heating element 32 outputs infrared radiation to the thin film, and the thin film absorbs the infrared radiation and generates heat to achieve heating.

[0041] In some embodiments, to facilitate the adjustment of the pitch angle of the housing 31 of the heating assembly 3, such as... Figure 2 As shown, the mounting bracket 2 is a U-shaped bracket, and the side of the mounting bracket 2 is provided with a first knob 21 for rotating the housing 31.

[0042] The pitch angle of the housing 31 can be adjusted by turning the first knob 21, which is convenient to operate.

[0043] In some embodiments, to facilitate adjustment of the height of the heating component 3, such as... Figure 1 As shown, a telescopic rod 11 is vertically mounted on the base 1, and the mounting bracket 2 is mounted on the top of the telescopic rod 11.

[0044] There are many ways to achieve telescopic adjustment of the telescopic rod 11. In this embodiment, the telescopic rod 11 includes a first rod body (not marked in the figure) and a second rod body (not marked in the figure). The first rod body and the second rod body are threaded together. The first rod body and the second rod body are respectively connected to the base 1 and the mounting bracket 2. Thus, this embodiment uses a relatively simple structure to achieve height adjustment of the heating component 3, and the manufacturing cost is low. Of course, in other embodiments, other lifting structures can also be used.

[0045] In some embodiments, to facilitate the transfer of the heating device, such as Figure 1 As shown, the base 1 is equipped with casters 12 at its bottom. This allows for flexible movement of the heating device and its easy installation onto the biodegradable membrane production line. The casters 12 have a self-locking function.

[0046] In some embodiments, such as Figure 3-5As shown, the shielding assembly 4 includes a mounting frame 41, multiple shielding plates 42, a connecting rod 43, and a second knob 44. The mounting frame 41 is located at the opening 311 of the housing 31. The multiple shielding plates 42 are mounted on the mounting frame 41, with both ends of each shielding plate 42 respectively located on a first rotating shaft 421. The shielding plates 42 are rotatably mounted on the mounting frame 41 via the first rotating shaft 421. A gap is formed between adjacent shielding plates 42. A second rotating shaft 422 is also provided on each shielding plate 42. The second rotating shaft 422 is parallel to the first rotating shaft 421. The connecting rod 43 is hinged to the second rotating shaft 422 on the multiple shielding plates 42. The second knob 44 is fixedly connected to the first rotating shaft 421 of one of the shielding plates 42.

[0047] In this embodiment, when the second knob 44 is rotated, the second knob 44 will drive one of the shielding plates 42 to rotate on the mounting frame 41 through the first rotating shaft 421, and the shielding plate 42 will drive the other shielding plates 42 to rotate through the connecting rod 43, so that all shielding plates 42 rotate synchronously; when the shielding plate 42 rotates, the cross-sectional area of ​​the gap between adjacent shielding plates 42 will change, thereby adjusting the amount of energy output to the thin film by the heating component 3.

[0048] In summary, this application provides a biodegradable membrane heating device that is easy to transport and can be quickly installed and disassembled on the production line without requiring large-scale modifications to the production line, thus reducing interference with the production schedule. The mounting frame 2 is height-adjustable, allowing for flexible adjustment of the height of the heating component 3 according to the position of the film. The housing 31 has a damped hinge that allows for free rotation and stable positioning, and can adjust the angle according to the direction of the film to accurately deliver heating energy. The shielding component 4 can control the energy output cross-sectional area, facilitating energy adjustment and meeting the temperature requirements before film stretching while preventing overheating and damage.

[0049] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
