Description

Technical Field

[0001] The present invention relates to the technical field of molded air duct forming, and specifically to a continuous production and processing device and process method for molded energy-saving air ducts. Background Art

[0002] In past usages, "molding" mostly referred to a process of plastic forming and processing. Under pressure (usually with heating simultaneously), plastic materials are formed by means of a mold or a die. Here, "mold" is used to modify "molding". In a patent application with the publication number CN118636427A, an extrusion device for pipes that prevents foaming and cools down, includes a connecting pipe and a fixed pipe. An activity pipe is fixedly installed on the connecting pipe. One end of the activity pipe can be connected to the fixed pipe. An activity plate is fixedly installed at one end of the activity pipe close to the fixed pipe. A plurality of activity threaded members are rotatably installed on the activity plate. A fixed plate is fixedly installed at one end of the fixed pipe close to the activity pipe. At a position corresponding to the activity threaded members on the fixed plate, a fixed threaded rod is fixedly installed. The fixed threaded rod is threadedly connected to the activity threaded members. A connecting frame is fixedly installed inside the fixed pipe close to the activity pipe. An internal fixing member is fixedly installed between the connecting frames. An extrusion chamber is formed between the internal fixing member and the activity pipe. However, the thermoplastic air duct parts extruded in the above document are at a relatively high temperature when they first come out. Once the ambient temperature is relatively low, they will come into contact with cold air, resulting in too fast a cooling speed. This fails to solve the problem of the cross-sectional shape of the pipe changing due to its own weight or external force. And when cooling rapidly, it is easy to cause too large a temperature difference between the inner and outer layers of the pipe, generating internal stress, which will also cause problems such as cracking or deformation.

[0006] Preferably, a sliding groove is provided inside the rotating sleeve, a heat preservation groove is provided on the inner wall of the rotating sleeve, and the rotating sleeve is slidably connected to the outer wall of the cage plate through the sliding groove.

[0007] Preferably, the interior of the extrusion tube is communicated with the interior of the extrusion head, and the interior of the extrusion head is communicated with the interior of the rotating sleeve.

[0008] Preferably, the outer wall of the rotating sleeve is provided with an adaptive change mechanism, and the adaptive change mechanism includes a motion detection sensor, and the motion detection sensor is fixedly connected to the inner wall of the insulation tank, and the motion detection sensor is electrically connected to the hollow shaft motor, and the motion detection sensor is used to control the rotation speed of the hollow shaft motor.

[0011] Preferably, an elastic strip is fixedly connected to one side of the fixing ring close to the rotating sleeve, one end of the elastic strip is fixedly connected to one side of the rotating sleeve, and the elastic strip is used to reset the fixing ring and the cage plate.

[0012] A molded energy-saving air duct continuous production and processing device comprises the following steps: S1: Put the plastic particles into the feed box, then start the extruder to melt, and melt the plastic particles through internal high temperature heating; S2: The melted solution is extruded to the outside through the extrusion tube and the mold inside the extrusion head, and cooled and shaped; S3: The extruded plastic part enters the rotating sleeve and the covering plate, and the rotation of the rotating sleeve and the covering plate is used to shape the plastic part and slowly cool it. Then, as the extrusion continues, the plastic part is separated from the rotating sleeve and the covering plate to complete the molding of the air duct.

[0013] The present invention provides a molded energy-saving air duct continuous production and processing device and a process method thereof. It has the following beneficial effects: 1. The present invention sets a stepped cooling mechanism to achieve that when the plastic material is just extruded from the pipe, it is in a high-temperature molten state. The material is extremely soft and easy to deform. It is slowly cooled by heat preservation, and the semi-heat preservation and semi-heat dissipation method of the subsequent cover plate is used to avoid the cross-sectional shape of the pipe being changed due to its own weight or external force, and to avoid rapid cooling that may cause excessive temperature difference between the inner and outer layers of the pipe and generate internal stress. After heat preservation, the overall temperature of the pipe is more uniform, and slow cooling can significantly reduce the internal stress, avoiding the risk of cracking or deformation in the later stage.

[0014] 2. The present invention provides a stepped cooling mechanism, so that when the plastic material passes through the inner wall of the rotating sleeve and the inner wall of the cage plate, the rotating sleeve will be quickly rotated to form a circular wrapped state, so that the newly extruded material will not be deformed due to the high temperature and soft texture, and the high-temperature plastic material can be shaped by rotating the wrapping; 3. The present invention provides a stepped cooling mechanism to ensure that the plastic material will not be easily deformed when passing through the rotating sleeve and the covering plate for stable fit and wrapping for heat dissipation. As the plastic material passes through the rotating sleeve and the covering plate one by one due to its own gravity, the surface will not be uneven due to the pressure caused by the downward pressure. While achieving slow heat preservation and cooling of the shaping, the smoothness and stability of the surface can be ensured simultaneously. The interlaced separation method of the rotating sleeve and the covering plate can also allow the extruded plastic parts to remain in the channel with the same inner diameter even if they pass through different heat dissipation channels, thereby avoiding deformation of their own diameter.

[0015] 4. The present invention sets an adaptive change mechanism. As the rotating sleeve rotates faster, the hinged rod is lifted and opened at a larger angle. Then, the distance to the right by pulling the cover plate by the elastic pull rope is further, and the total length of the stepped sleeve formed by the rotating sleeve and the cover plate is correspondingly increased, so that the plastic material whose residence time in the rotating sleeve and the cover plate is shortened can stay longer, completing the preset stepped stable heat dissipation work, and will not cause the problem of too short extrusion cooling time of the plastic material due to the change of extrusion speed.

[0016] 5. The present invention sets an adaptive change mechanism. As the hinged rod is lifted and opened, the hinged rod will pull the elastic cloth at the bottom. The elastic cloth can be deformed to form a fan-shaped wind-collecting surface, which drives the air to flow quickly. The faster the plastic parts are extruded, the larger the area of ​​the elastic cloth that is pulled and opened is, thereby forming a more efficient heat dissipation effect, avoiding the deformation problem caused by the short heat dissipation time when the high-temperature plastic parts are extruded quickly, so that while extending the insulation time, the insulation effect during rapid extrusion is reduced as much as possible, so that the temperature of the plastic parts after leaving the insulation structure will not differ too much from the low temperature of the environment.

DETAILED DESCRIPTION

[0019] Example 1: Please refer to Figure 1-4The present invention provides a technical solution: a molded energy-saving air duct continuous production and processing device, comprising a bottom plate 1, an extruder 2 is fixedly connected to the top of the bottom plate 1, an extrusion tube 5 is fixedly connected to one side of the extruder 2, a feed box 7 is arranged on the top of the extruder 2, an extrusion head 6 is fixedly connected to one side of the extrusion tube 5, and a stepped cooling mechanism 3 is arranged on one side of the extrusion tube 5; The stepped cooling mechanism 3 comprises: A hollow shaft motor 301, one side of the hollow shaft motor 301 is fixedly connected to one side of the extrusion tube 5, a rotating sleeve 302 is fixedly connected to the output end of the hollow shaft motor 301, and a connecting block 303 is fixedly connected to the inner wall of the rotating sleeve 302. The connecting block 303 is a square frame structure, and the hollow shaft motor 301 is used to drive the rotating sleeve 302 and the connecting block 303 to rotate; A plane bearing 307, which is a circular ring structure. One side of the plane bearing 307 is fixedly connected to one side of the extrusion head 6, and the other side of the plane bearing 307 is fixedly connected to a rotating sleeve 304. A cover plate 305 is provided on one side of the rotating sleeve 304; When in use, the plastic particles are put into the feed box 7, and then the extruder 2 is started to melt, and the internal extrusion pieces are melted and then extruded through the extrusion tube 5 and the extrusion head 6 to form a circular air duct, thereby completing the molding of the air duct; When the plastic material is extruded, the hollow shaft motor 301 is synchronously started to control the rotation of the rotating sleeve 302 and the connecting block 303. When the connecting block 303 rotates, the rotating sleeve 304 is driven to rotate. When the rotating sleeve 304 rotates, it can freely rotate on one side of the extruder head 6 through the plane bearing 307, so that when the plastic material passes through the inner wall of the rotating sleeve 304 and the inner wall of the cage plate 305, the rotating sleeve 304 is used to form a circular wrapping state, so that the newly extruded material will not be deformed due to the high temperature and soft texture, and the high-temperature plastic material can be shaped by rotating and wrapping; Example 2: Please refer to Figure 1-9 On the basis of the first embodiment, the present invention provides a technical solution: the inner wall of the rotating sleeve 304 is slidably connected to the outer wall of the covering plate 305, and the end of the covering plate 305 away from the rotating sleeve 304 is fixedly connected with a fixing ring 306, and the fixing ring 306 is a circular ring structure.

[0020] A sliding groove 308 is provided inside the rotating sleeve 304 , and a heat preservation groove 309 is provided on the inner wall of the rotating sleeve 304 . The rotating sleeve 304 is slidably connected to the outer wall of the covering plate 305 via the sliding groove 308 .

[0021] The interior of the extrusion tube 5 is connected to the interior of the extrusion head 6, and the interior of the extrusion head 6 is connected to the interior of the rotating sleeve 304; When the air duct is extruded through the extruder head 6, it will first enter the inner wall of the rotating sleeve 304, and as it continues to be pushed outward, it will enter the inner wall of the cover plate 305, and finally be discharged through the opening of the fixing ring 306. In this process, the plastic material with a higher temperature will first contact the inner wall of the rotating sleeve 304 after being extruded from the extruder head 6, and the inner wall of the rotating sleeve 304 is provided with a heat preservation groove 309, so there is air between the plastic material and the heat preservation groove 309, thereby reducing the heat conduction of direct contact. The air in the heat preservation groove 309 is not circulated, and the air is a poor conductor of heat, which can achieve the heat preservation effect on the plastic material for a period of time, and achieve slow cooling through the inner wall of the rotating sleeve 304 with a small contact area, and continue to be extruded It will enter the cover plate 30 5, there is a gap between the shielding plates 305 and the shielding plates 305, so as to utilize the low temperature of the air connected to the outside to further open it for heat dissipation, and at the same time utilize the contact between the plastic material and the shielding plate 305, the shielding plate 305 is a heat absorbing material, and completes a stable and uniform heat absorption effect, so that the pipe just extruded by the plastic material is in a high-temperature molten state, and the material is extremely soft and easy to deform. It is slowly cooled by heat preservation, and the subsequent half-heat preservation and half-heat dissipation method of the shielding plate 305 is used to avoid the cross-sectional shape of the pipe being changed due to its own weight or external force, and to avoid rapid cooling that easily causes excessive temperature difference between the inner and outer layers of the pipe, resulting in internal stress. After heat preservation, the overall temperature of the pipe is more uniform, and slow cooling can significantly reduce internal stress, avoiding the risk of cracking or deformation in the later stage; At the same time, it can also ensure that the plastic material will not be easily deformed when passing through the rotating sleeve 304 and the covering plate 305 for stable adhesion and wrapping for heat dissipation. As the plastic material passes through the rotating sleeve 304 and the covering plate 305 one by one due to its own gravity, the surface will not be uneven due to the pressure caused by the pressing depression. While achieving slow heat preservation and cooling of the shaping, the surface is also ensured to be smooth and stable. The interlaced separation method of the rotating sleeve 304 and the covering plate 305 can also keep the extruded plastic parts in the channel with the same inner diameter even if they pass through different heat dissipation channels, thereby avoiding deformation of their own diameter. Example 3: Please refer to Figure 1-14 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the outer wall of the rotating sleeve 304 is provided with an adaptive change mechanism 4, the adaptive change mechanism 4 includes a motion detection sensor 401, the motion detection sensor 401 is fixedly connected with the inner wall of the heat preservation tank 309, the motion detection sensor 401 is electrically connected to the hollow shaft motor 301, and the motion detection sensor 401 is used to control the rotation speed of the hollow shaft motor 301.

[0022] The outer wall of the rotating sleeve 304 is fixedly connected with a hinge block 402 , the inner wall of the hinge block 402 is hinged with a hinge rod 403 , one end of the hinge rod 403 is fixedly connected with an elastic pull rope 404 , and one end of the elastic pull rope 404 is fixedly connected to the outer wall of the covering plate 305 .

[0023] The bottom of the hinge rod 403 is fixedly connected with an elastic cloth 405 , and the elastic cloth 405 is elastic.

[0024] The side of the fixed ring 306 close to the rotating sleeve 304 is fixedly connected with an elastic strip 406, one end of the elastic strip 406 is fixedly connected to one side of the rotating sleeve 304, and the elastic strip 406 is used to reset the fixed ring 306 and the cover plate 305; When the plastic material moves radially along the rotating sleeve 304 and the cover plate 305, the motion detection sensor 401 arranged in the heat preservation tank 309 can detect the speed of the plastic material passing radially through the rotating sleeve 304 and the cover plate 305, and proportionally adjust the hollow shaft motor 301 to control the rotation speed of the rotating sleeve 302 according to the extrusion speed. When the speed of the extruded plastic material is faster, the rotating sleeve 302 drives the connecting block 303, the rotating sleeve 304 and the cover plate 305 to rotate faster. Therefore, the rotating sleeve 304 and the cover plate 305 will accelerate their rotation correspondingly when the plastic material passes quickly to ensure its stable shaping. When the extrusion speed is increased, the plastic material will be retained in the step-wise heat dissipation between the rotating sleeve 304 and the cover plate 305 for a shorter time. At this time, when the rotation speed of the rotating sleeve 304 and the cover plate 305 is correspondingly increased, the rotating sleeve 304 will centrifugally swing the outer wall outward through the hinged rod 403 hinged by the hinge block 402 to lift a larger angle, so that when the hinged rod 403 is lifted, the elastic pull rope 404 is pulled, and the elastic pull rope 404 can be stretched by elastic force, and the connected cover plate 305 is pulled synchronously. The faster the rotation speed of 304 is, the greater the lifting and opening angle of the hinge rod 403 is, and the farther the distance that the cover plate 305 is pulled to the right by the elastic pull rope 404 is, the total length of the stepped sleeve formed by the rotating sleeve 304 and the cover plate 305 is correspondingly increased, so that the plastic material whose residence time in the rotating sleeve 304 and the cover plate 305 is shortened can stay longer, completing the preset stepped stable heat dissipation work, and will not cause the problem of too short extrusion cooling time of the plastic material due to the change of extrusion speed; As the hinge rod 403 is lifted and opened, the hinge rod 403 will pull the elastic cloth 405 at the bottom, and the elastic cloth 405 can be deformed to form a fan-shaped wind-absorbing surface, which drives the air to flow quickly. When the plastic part is extruded faster, the elastic cloth 405 is pulled and opened to a larger area, thereby forming a more efficient heat dissipation effect, avoiding the deformation problem caused by the short heat dissipation time when the high-temperature plastic part is extruded quickly, so that the heat preservation effect during fast extrusion is reduced as much as possible while extending the heat preservation time, so that the temperature of the plastic part after leaving the heat preservation structure will not differ too much from the low temperature of the environment; When the speed of extruding the plastic part is fast, as the cover plate 305 is pulled out of the rotating sleeve 304, the cover plate 305 will open the sliding groove 308 that originally covers the rotating sleeve 304, so that the sliding groove 308 is also opened synchronously, so that when the high-temperature plastic part is extruded quickly, the area of ​​the connecting passage between the open rotating sleeve 304 and the external air is used to further improve the corresponding cooling efficiency of the plastic part, ensuring that it can be fully cooled in this state; When the rotation speeds of the rotating sleeves 302 and 304 decrease, the cover plate 305 will be pulled back to its original position by the elastic force of the elastic strip 406 , thereby achieving the function of the cover plate 305 being inserted into the interior of the rotating sleeve 304 .
