Description

Technical Field

[0001] This utility model relates to the field of color-printed mulch film production technology, and in particular to an energy-saving heating cover for a plastic extruder used in the production of color-printed mulch film. Background Technology

[0002] In the field of color-printed mulch film production, plastic extruders are the core equipment for melting and shaping raw materials. Currently, the production of color-printed mulch film has extremely high requirements for the uniformity of raw material melting. It is necessary to ensure that the masterbatch is evenly dispersed in the molten raw material to ensure the consistency of the mulch film color. At the same time, functional additives (such as anti-aging agents, heat-insulating agents, etc.) need to be fully mixed to achieve the specific performance of the mulch film. All of this depends on the uniformity of the heating environment on the outer surface of the plastic extruder.

[0003] Existing plastic extruder heating systems generally suffer from prominent problems such as high heat loss, uneven heating, and long preheating time, resulting in low energy utilization and limited production efficiency. Therefore, we have launched a new energy-saving heating cover for plastic extruders used in the production of color-printed mulch films. Utility Model Content

[0004] The main objective of this invention is to provide an energy-saving heating cover for plastic extruders used in the production of color-printed mulch films, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An energy-saving heating cover for a plastic extruder used in the production of color-printed mulch film includes a heating cover body with a heating chamber inside. Two fixing plates are fixedly connected to the upper right side of the heating cover body, and a heating mechanism is fixedly installed inside the two fixing plates. Fixing openings are provided at the middle of the left and right ends of the heating cover body, and sealing rings are provided inside the two fixing openings. Supporting mechanisms are fixedly connected to the lower left and lower right ends of the heating cover body. A control panel is provided at the front end of the heating cover body.

[0006] Preferably, the heating mechanism includes a heating fan, an air inlet pipe is fixedly connected to the output end of the heating fan, a diverter pipe is fixedly connected to the end of the air inlet pipe away from the heating fan, a plurality of connecting pipes are fixedly connected to the lower part of the outer surface of the diverter pipe, a heating tube is fixedly connected to the lower end of each of the plurality of connecting pipes, a support block is fixedly connected to the front and rear parts of the outer surface of each of the plurality of heating tubes, and a plurality of air outlets are fixedly connected to the inner surface of each of the plurality of heating tubes.

[0007] Preferably, the heating fan is fixedly installed inside two fixed plates, the air inlet pipe is inserted and fixedly connected to the upper wall of the heating chamber, and the diversion pipe and several heating pipes are all located inside the heating chamber.

[0008] By adopting the above technical solution: the heating fan serves as the source of hot air, and the air inlet pipe connected to its output end can guide the generated hot air into the distribution pipe. The distribution pipe then distributes the hot air to each heating pipe through several connecting pipes, forming a complete and efficient hot air delivery path.

[0009] Preferably, the heating tubes are distributed at equal distances, and the axis of the heating tubes is horizontally aligned with that of the two fixed ports.

[0010] By adopting the above technical solution: several heating tubes are distributed at equal intervals, which can form uniform heating points along the length of the plastic extruder, ensuring that each section of the extruder is heated evenly. The heating tubes are horizontally aligned with the axis of the two fixed ports, ensuring that the relative positions of the heating tubes and the extruder inserted in the fixed ports are precisely aligned, so that the air outlets on the heating tubes can face the outer surface of the extruder, ensuring that the hot air acts directly on the parts that need to be heated, reducing heat diffusion and waste, and improving heating uniformity.

[0011] Preferably, the ends of the several support blocks away from the heating tube are fixedly connected to the inner wall of the heating cavity, and the several air outlets are arranged in a ring array.

[0012] By adopting the above technical solution, several air outlets are arranged in a ring array, which can deliver hot air to the outer surface of the extruder from multiple angles, achieving full coverage of the circumference of the extruder and further improving the heating uniformity.

[0013] Preferably, the support mechanism includes a support base, and an ear plate is fixedly connected to the lower left end of the support base. Mounting bolts are inserted and connected to the front upper end and the rear upper end of the ear plate.

[0014] Preferably, the upper end of the support base is fixedly connected to the heating cover, and the two mounting bolts are symmetrically distributed front and back.

[0015] By adopting the above technical solution, the support base is fixedly connected to the heating cover, which can support the heating cover. The two mounting bolts are symmetrically distributed front and back, so that the support base and the mounting surface are evenly stressed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the coordinated operation of the heating fan, air inlet pipe, distribution pipe, and connecting pipe, hot air is delivered to multiple heating pipes evenly distributed along the length of the plastic extruder. The hot air is then evenly distributed through air outlets arranged in a ring array on the outer surface of the extruder. This combination of ring-array air outlets and evenly spaced heating pipes ensures that hot air fully covers the outer surface of the plastic extruder, creating a highly uniform heating environment. This shortens the preheating time after the extruder starts up, improving energy efficiency. Simultaneously, the uniform heating environment promotes the even dispersion of color masterbatch and functional additives in the raw materials during the production of color-printed plastic film, reducing rework and re-production due to substandard product performance. Rework and re-production not only repeatedly consume raw materials but also occupy the operating time of equipment such as the plastic extruder, causing the equipment to consume energy again for heating and extrusion processes. Therefore, reducing rework and re-production indirectly reduces energy waste in the production process, forming a dual energy-saving effect of directly reducing preheating energy consumption and indirectly reducing rework energy consumption, thus lowering the company's energy costs. 2. The plastic extruder is inserted and fixed in the two fixing ports. The sealing rings at the two fixing ports can fit tightly against the outer wall of the plastic extruder and the edge of the fixing ports, sealing the gap between them and preventing the heat inside the heating hood from escaping through the gap, thus reducing heat loss. By fixing two support seats at the bottom of the heating hood, the hood can be supported. The heating hood can be fixed to the mounting surface by mounting bolts, which not only strengthens the support effect of the support seats, but also makes the heating hood fixed in the installation position for use.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: An energy-saving heating cover for a plastic extruder used in the production of color-printed mulch film includes a heating cover body 1, a heating chamber 2 inside the heating cover body 1, two fixing plates 3 fixedly connected to the upper right side of the heating cover body 1, a heating mechanism 4 fixedly installed inside the two fixing plates 3, fixing openings 5 ​​at the middle of the left and right ends of the heating cover body 1, sealing rings 6 inside the two fixing openings 5, support mechanisms 7 fixedly connected to the lower left and lower right ends of the heating cover body 1, and a control panel 8 at the front end of the heating cover body 1.

[0023] In this embodiment, the heating mechanism 4 includes a heating fan 41. The output end of the heating fan 41 is fixedly connected to an air inlet pipe 42. The end of the air inlet pipe 42 away from the heating fan 41 is fixedly connected to a diversion pipe 43. A plurality of connecting pipes 44 are fixedly connected to the lower part of the outer surface of the diversion pipe 43. A heating pipe 45 is fixedly connected to the lower end of each of the plurality of connecting pipes 44. A support block 46 is fixedly connected to the front and rear parts of the outer surface of each of the plurality of heating pipes 45. A plurality of air outlets 47 are fixedly connected to the inner surface of each of the plurality of heating pipes 45. The heating fan 41 is fixedly installed in two fixed plates 3. The air inlet pipe 42 is inserted and fixedly connected to the upper wall of the heating cavity 2. The diversion pipe 43 and the plurality of heating pipes 45 are all located inside the heating cavity 2. The plurality of heating pipes 45 are distributed at equal distances and are horizontally aligned with the axis of the two fixed ports 5. The ends of the plurality of support blocks 46 away from the heating pipes 45 are fixedly connected to the inner wall of the heating cavity 2. The plurality of air outlets 47 are arranged in a ring array.

[0024] Through the above scheme: using the heating fan 41 as the power source, the generated hot air is transported to the distribution pipe 43 through the air inlet pipe 42. The distribution pipe 43 then distributes the hot air evenly to multiple equally spaced heating pipes 45 through several connecting pipes 44. Since the heating pipes 45 are horizontally aligned with the axis of the fixed port 5, it can ensure that the heating pipes 45 and the plastic extruder inserted in the fixed port 5 are precisely aligned, so that the heating pipes 45 can form a uniform heating unit along the length of the extruder. At the same time, the air outlets 47 distributed in a ring array on the inner surface of the heating pipes 45 can deliver hot air from the circumference of the extruder, creating a highly uniform heating environment.

[0025] In this embodiment, the support mechanism 7 includes a support base 71, an ear plate 72 is fixedly connected to the lower left end of the support base 71, and mounting bolts 73 are inserted and connected to the front and rear upper ends of the ear plate 72. The upper end of the support base 71 is fixedly connected to the heating cover 1, and the two mounting bolts 73 are symmetrically distributed front and back.

[0026] The above solution uses a support base 71 as a load-bearing component, with its upper end fixedly connected to the heating cover 1, which can bear the weight of the heating cover 1. The ear plate 72 at the left end of the support base 71 is fixed to the mounting surface by mounting bolts 73 symmetrically distributed at the front and rear. This not only strengthens the support effect of the support base 71, but also facilitates the installation of the heating cover 1.

[0027] It should be noted that this utility model is an energy-saving heating cover for a plastic extruder used in the production of color-printed mulch film. During use, two support seats 71 are fixed at the bottom of the heating cover 1 to provide stable support. The heating cover 1 is fixed to the mounting surface with mounting bolts 73, which not only enhances the support effect of the support seats 71, but also ensures that the heating cover 1 is stably positioned for use. The plastic extruder is inserted and fixed inside the two fixing ports 5. At the same time, the sealing rings 6 configured at the two fixing ports 5 can tightly fit the outer wall of the plastic extruder and the edge of the fixing ports 5, effectively sealing the gap between them and preventing the heat inside the heating cover 1 from escaping through the gap, thereby reducing heat loss. After the heating fan 41 is started, the heating fan 41 is used as the hot air source. The hot air generated by the heating fan 41 is transported to the distribution pipe 43 through the air inlet pipe 42. The distribution pipe 43 then distributes the hot air evenly to multiple equally spaced heating pipes 45 through several connecting pipes 44. Due to the axial position of the heating pipes 45 and the fixing ports 5, Maintaining a consistent horizontal alignment ensures precise alignment between the heating tube 45 and the plastic extruder inserted into the fixed port 5, allowing the heating tube 45 to form a uniform heating unit along the length of the extruder. Simultaneously, the air outlets 47, arranged in a ring array on the inner surface of the heating tube 45, deliver hot air comprehensively from the circumference of the extruder, creating a highly uniform heating environment. This shortens the preheating time after the extruder starts up, improving energy efficiency. Furthermore, the uniform heating environment promotes the even dispersion of color masterbatch and functional additives in the raw materials during the production of color-printed agricultural films, reducing rework and re-production due to substandard product performance. Rework and re-production not only repeatedly consume raw materials but also occupy the operating time of equipment such as the plastic extruder, causing the equipment to consume energy again for heating and extrusion processes. Therefore, reducing rework and re-production can further indirectly reduce energy waste in the production process, ultimately achieving a dual energy-saving effect of directly reducing preheating energy consumption and indirectly reducing rework energy consumption, thus lowering the company's energy costs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
