Description

Technical Field

[0001] This invention relates to the field of automotive seat clip production technology, specifically to a water-cooled drying equipment and production system for automotive seat clips. Background Technology

[0002] Appendix Figure 13 The cross-sectional structure of a car seat clip body 01 is shown. The main body 011 has a side plate 012 formed on its side, and protrusions A013 and B014, which serve as a buckle structure, are formed on its bottom. The protrusions at both locations form corner structures with the bottom surface of the main body 011 and with the side plate 012.

[0003] This clip is manufactured using an extrusion molding process. The existing conventional cooling and shaping process involves immersing the extruded profile entirely in cooling water. However, when this process is applied to this type of clip, the significant difference in surface area between the plate and the clipping area leads to a severe imbalance in the cooling rate of the profile: the clipping area, being small in volume and surface area, cools down quickly and completes shaping first; the larger plate structures, such as the main plate 011 and side plate 012, cool down slowly, exhibiting a significant cooling lag. This ultimately results in uneven cooling and shrinkage across different parts of the profile, easily causing warping and deformation, exceeding tolerances in critical dimensions, and a high product defect rate.

[0004] In addition, due to the complex irregular cross-section of the card strip, subsequent drying and impurity removal are difficult. Summary of the Invention

[0005] Based on the above-mentioned technical problems, this application provides a water-cooled drying equipment and production system for automotive seat clips, which first drips water to cool the product plate structure, and then immerses the entire plate in water cooling to ensure the molding quality of the clips.

[0006] On one hand, this application provides a water-cooled drying device for automotive seat clips, including a drive mechanism and a drip cooling unit, an immersion water cooling unit, and a hot air drying unit that are sequentially connected along the conveying direction of the automotive seat clip body; The drip cooling unit includes an inner tube and an outer cylinder; The inner tube is horizontally fixed to the side of the base plate, the outer cylinder is sleeved on the outside of the inner tube, and the driving mechanism can drive the outer cylinder to rotate. Several baffles are evenly distributed around the axis of the inner wall of the outer cylinder. Each baffle extends radially along the inner tube and is movably fitted to the outer wall of the inner tube. A flow divider is formed between two adjacent baffles. The inner tube is equipped with a drip hole group at the top and a return hole group at the bottom. Water baffles are fixed on both sides of the return hole group on the inner wall of the inner tube. As the outer cylinder rotates, when the flow distribution chamber moves to coincide with the drip hole group, water drips through the drip hole group onto the main body and side plate, achieving drip cooling.

[0007] In one implementation, the immersion water cooling unit includes a water cooling tank and a minor interference flow wheel; The water-cooling tank has a U-shaped cross-section, with one end fixed to the side of the substrate away from the inner tube, and the substrate has a through hole connecting the water-cooling tank and the inner tube. The bottom of the water-cooling tank has several recessed sections arranged along the length of the water-cooling tank on the side closest to the substrate. Each of the turbulence-inducing water wheels is correspondingly located in the submerged section. The drive mechanism can simultaneously drive the turbulence-inducing water wheels to rotate in the corresponding submerged section, so as to create a surge in the water cooling tank and above each submerged section where the liquid level is higher than the body of the car seat clip.

[0008] In one implementation, two baffles are fixed on the side of the water-cooling tank away from the substrate, and an immersion water-cooling cavity is formed between the two baffles in the water-cooling tank. Both baffles are provided with through holes of equal height for the car seat clip body to pass through. The liquid level inside the water-cooling chamber is higher than the upper surface of the car seat clip body.

[0009] In one implementation, a water storage area is formed inside the inner pipe between two baffles; A water supply unit is provided below the end of the water-cooling tank away from the substrate for supplying water to the immersion water-cooling cavity; The water immersed in the water-cooling cavity can flow into the water storage area inside the inner tube.

[0010] In one implementation, the turbulence impeller includes a shaft and a minor turbulence plate; The shafts are rotatably installed in the sunken part in a one-to-one correspondence, and the outer walls of each shaft are evenly distributed with spoilers.

[0011] In one implementation, the drive mechanism includes a drive motor, a rotating shaft, and gears; A mounting base is fixed to the side of the water-cooling tank, and a rotating shaft is rotatably mounted on the mounting base and extends along the length of the water-cooling tank. The drive motor is fixed on the mounting base, and its output shaft is fixedly connected to the end of the rotating shaft; The rotating shaft passes through the substrate and is rotatably connected to the substrate. The gear is fixed on the end of the shaft away from the drive motor, and a gear ring is fixed on the side of the outer cylinder, and the gear ring meshes with the gear.

[0012] In one implementation, one end of each shaft extends through to the outside of the recessed portion and is fixedly mounted with a worm gear body; Each shaft is equipped with a helical section at a position corresponding to the position of each worm gear body; The helical part and the rotating shaft form a worm structure, and the worm structure meshes with the worm wheel body in a one-to-one correspondence.

[0013] In one implementation, the hot air drying unit includes a drying cylinder, a reversing shroud, a suction pipe, and a pair of annular pipes; The drying cylinder is located on the downstream side of the water-cooling tank, and annular pipes are fixed on the inner wall of the drying cylinder near both ends. Several jet nozzles are arranged in a ring around the axis of the drying cylinder on the annular tube. The jet nozzles on the same side are clustered together towards one side of the other annular tube; Both annular pipes are connected to air supply pipes, and the air supply pipes are connected to external hot air blowers. The reversing cover is fixed inside the drying cylinder and located at the center between the two annular tubes. Several suction ports that communicate with the interior are evenly distributed around the axis of the drying cylinder on the inner edge wall of the reversing cover. The reversing cover is connected to the suction pipe, and the other end of the suction pipe is connected to an external industrial vacuum cleaner.

[0014] In one implementation, the water supply unit includes a water storage tank, a water supply pump, and a water supply pipe; The water storage tank is located below the end of the water-cooling tank furthest from the substrate, and has an opening at the top for receiving water discharged from the end of the water-cooling tank furthest from the substrate. The water supply pump is located at the bottom of the water storage tank. One end of the water supply pipe is connected to the water supply pump, and the other end is connected to the side of the water cooling tank and communicates with the immersion water cooling cavity. The inner tube has an upward-facing water collection tank at the lower end away from the base plate. The bottom of the water collection tank is connected to a return water pipe, and the other end of the return water pipe is connected to a water storage tank.

[0015] On the other hand, this application also provides an automotive seat clip production system, which includes the aforementioned water-cooled drying equipment.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0017] The directional and quantitative dripping pre-cooling structure formed by the inner tube and outer cylinder can accurately pre-cool and shape the main body and side plate with lagging temperature drop rate, reduce the initial temperature difference between them and protrusions A and B, solve the problem of unbalanced cooling rate in existing processes, effectively suppress the defects of uneven cooling shrinkage and warping deformation of profiles, and improve the accuracy of key dimensions and batch consistency of products.

[0018] The water cooling structure is formed by intermittent liquid surface surge water cooling through the spaced turbulent water wheels in the water cooling tank. Combined with the constant liquid level immersion shaping in the end water cooling cavity, a temperature homogenization process is formed in the adjacent surge intervals. This avoids the secondary imbalance of cooling rate caused by continuous immersion. At the same time, it can flush out heat exchange bubbles and hot water layers trapped at the interface, enhance heat exchange efficiency, and finally achieve full-structure immersion cooling of the profile without dead angles, effectively improving the molding quality of the car seat clip body.

[0019] The opposing hot air flow inside the drying cylinder forms a hot air field that completely wraps around the profile, thoroughly blowing away residual water droplets on the profile surface and in the corner gaps. Combined with the negative pressure suction in the middle, it can promptly discharge hot and humid air. At the same time, it can peel off impurities from the profile surface and gaps without contact, avoiding secondary adhesion of impurities and scratches on the profile surface.

[0020] The outer cylinder and each set of turbulent water wheels are driven synchronously by a single power source of drive motor, which greatly simplifies the equipment transmission structure and reduces manufacturing costs and failure rate. At the same time, the closed-loop water circulation system formed by the water storage tank realizes the self-stabilized pressure supply of water from the overflow of the immersion water cooling chamber to the inner pipe, without the need for additional independent pressure regulating and pumping components, ensuring constant drip pressure and stable precooling effect.

[0023] In traditional conventional technology, the entire body 01 of the car seat clip is directly immersed in cooling water after extrusion. Due to the large difference in specific surface area between the main body 011, side plate 012 and protrusions A013 and B014, the cooling rate of each part is seriously unbalanced. Protrusions A013 and B014 cool down faster and set first, while the main body 011 and side plate 012 cool down later. This ultimately results in uneven cooling and shrinkage of the car seat clip body 01, warping and deformation, and out-of-tolerance of key dimensions, leading to a high product defect rate.

[0024] The industry's conventional approach to addressing this issue mainly involves adjusting cooling water temperature, extending cooling time, optimizing extrusion process parameters, or adding a simple overall spray pre-cooling process. None of these approaches address the core root cause of the imbalance in cooling rates between different structures and cannot fundamentally solve the aforementioned defects.

[0025] To address the aforementioned problems, this application provides an automotive seat clip production system. Please refer to [link / reference]. Figure 12 The production system includes a co-extruder 02, a water-cooled drying equipment, a traction machine 03, and a slitting machine 04, which are connected sequentially from upstream to downstream of the process. The traction machine 03 provides traction power for the entire process. The co-extruder 02 is equipped with an extrusion die. After the raw material is extruded and shaped by the co-extruder 02, it enters the water-cooled drying equipment for water cooling and shaping to obtain the car seat clip body 01. Then, the slitting machine 04 is used to cut the shaped car seat clip body 01 according to the size to obtain the final product.

[0026] Among them, the water-cooled drying equipment can first drip water-cool the product plate structure and then immerse the whole in water-cooling, which ensures the molding quality of the car seat strip body 01. This makes the production system effectively adaptable to the production process of the car seat strip body 01. The following is a detailed description in conjunction with the embodiments.

[0027] This invention is not limited to the specific embodiments listed below. Those skilled in the art can implement this invention using various other specific embodiments based on the content disclosed herein. Any modifications or alterations made to the design structure and concept of this invention fall within the protection scope of this invention. It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Please see Figures 1 to 11 The automotive seat clip water-cooled drying equipment includes a base plate 05 and a drip cooling unit, an immersion water cooling unit, and a hot air drying unit that are coaxially connected in sequence along the conveying direction of the automotive seat clip body 01. It also includes a drive mechanism for synchronously driving the drip cooling unit and the immersion water cooling unit, and a water supply unit for providing circulating cooling water to the equipment.

[0030] The substrate 05 serves as the mounting base for the equipment and is fixed on the base frame. The drip cooling unit and the immersion water cooling unit are respectively fixed on both sides of the substrate 05. The conveying channels of each unit are aligned to adapt to the extrusion direction of the upstream co-extruder 02, ensuring that the high-temperature car seat clip body 01 is conveyed smoothly along a straight line, and avoiding bending and deformation of the car seat clip body 01 due to its own weight, scratching deformation, or angle traction under high temperature conditions.

[0031] The drip cooling unit includes an inner tube 1 and an outer cylinder 2. The inner tube 1 is horizontally fixed to the feed side of the substrate 05. The inner cavity of the inner tube 1 is the primary conveying channel of the car seat clip body 01. Its feed end is coaxially set with the discharge port of the extrusion die of the upstream co-extruder 02, so that the freshly extruded high-temperature car seat clip body 01 directly enters the inner cavity of the inner tube 1.

[0032] like Figure 3 and Figure 4 As shown, the outer cylinder 2 is coaxially sleeved on the outside of the inner tube 1, and both ends of the inner tube 1 extend to the outside of the outer cylinder 2. The two ends of the outer cylinder 2 are rotatably connected to the outer wall of the inner tube 1 in a sealed manner (the sealed rotatable connection method adopts existing technology), ensuring that there is no radial movement during the rotation of the outer cylinder 2 and that the rotation is smooth.

[0033] Several baffles 21 are evenly distributed around the axis of the inner wall of the outer cylinder 2. Each baffle 21 extends radially along the inner tube 1, and the inner end of the baffle 21 slides against the outer wall of the inner tube 1. An independent diversion cavity 22 is formed between two adjacent baffles 21. This structure makes the volume of each diversion cavity 22 fixed, which can realize quantitative and intermittent dripping supply, fundamentally ensuring the uniformity and controllability of the dripping amount.

[0034] The inner tube 1 has a drip hole group 11 at the top and a return hole group 12 at the bottom. The hole structures in the drip hole group 11 and the return hole group 12 are evenly arranged along the length of the inner tube 1. Water baffles 13 are fixed on both sides of the return hole group 12 on the inner wall of the inner tube 1. A closed water storage area is formed between the two water baffles 13 to collect the water dripping from above and intercept and store a certain amount of water to ensure that the water level in the water storage area is constant, thereby ensuring that the drip pressure is stable without the need for additional independent pressure regulating and stabilizing components.

[0035] A small gap is left between the baffle plate 13 and the car seat clip body 01 to facilitate delivery. This gap does not interfere with the continuous delivery of the car seat clip body 01, and minimizes the leakage of water in the water storage area to both sides of the axis, thus further ensuring the stability of the dripping process.

[0036] It should be noted that the core cause of the cooling deformation of the car seat clip body 01 is the imbalance of cooling rates of different structures, rather than the cooling time or insufficient cooling water temperature. This application proposes a cooling and shaping approach that pre-cools the main body 011 and side plate 012, which have slow temperature drop, to reduce the initial temperature difference between them and the protrusions A013 and B014, which have fast temperature drop.

[0037] To achieve the aforementioned directional and quantitative precooling approach, this application designs a special structure in which a coaxially nested inner tube 1 and a rotatable outer cylinder 2 are fitted together. An independent diversion chamber 22, separated by a partition 21, works in conjunction with the drip hole group 11 and the return hole group 12 to form a closed-loop circulation of water filling, directional dripping, and return, as detailed below: Please see Figure 4 (The curved arrows in the figure indicate the rotation direction of the outer cylinder 2). The drive mechanism drives the outer cylinder 2 to rotate coaxially around the inner tube 1. The water level in each diversion cavity 22 is shown by the corresponding dotted lines. As shown by the straight arrows in the figure, when a diversion cavity 22 rotates to the position that coincides with the return hole group 12, the cooling water in the water storage area enters the diversion cavity 22 through the return hole group 12 to complete the quantitative water filling. As the outer cylinder 2 continues to rotate, the diversion cavity 22 carries the cooling water and rotates upward. When it rotates to the position directly above the main body 011 and side plate 012 of the car seat clip body 01, the cooling water continuously drips through the drip hole group 11 onto the surface of the main body 011 and side plate 012 under the action of gravity, and performs precise pre-cooling on the large-size structure.

[0038] When the above-mentioned droplets fall on the upper surface of the car seat clip body 01, they will be diverted to both sides. After flowing past both sides of the car seat clip body 01, they will fall into the water storage area between the two baffles 13 under the action of gravity, and then flow back to the diversion chamber 22 through the return hole group 12 to achieve circulation.

[0039] The above mechanism forms a liquid flow that mainly covers the upper part and sides of the main body 01 of the car seat clip, which can first pre-cool and shape the large surfaces of the main body 011 and the side body 012. Then a small amount of liquid will contact the protrusions A013 and B014 to achieve delayed cooling of the protrusions A013 and B014, so that the overall structure is initially shaped.

[0040] It is evident that the above-mentioned drip cooling mechanism is completely different from conventional continuous spraying or fixed drip hole structures (conventional structures cannot achieve directional and quantitative dripping; either the overall coverage causes the snap-fit ​​structure to cool prematurely, exacerbating the rate imbalance problem, or the uncontrollable dripping volume leads to unstable pre-cooling effect).

[0041] The diameter, number, and distribution of the drip holes in the drip hole group 11 can be adapted and adjusted according to the overall width of the car seat card strip body 01 to ensure that the drip coverage area is completely matched with the plate structure, thereby further improving the accuracy of pre-cooling.

[0042] like Figure 5 As shown, the immersion water cooling unit includes a water cooling tank 3 and a water impeller 4. The cross-section of the water cooling tank 3 is U-shaped, and one end of it is fixed to the side of the substrate 05 away from the inner tube 1. The substrate 05 has a through hole that connects the inner tube 1 and the water cooling tank 3.

[0043] The bottom of the water-cooled tank 3 is provided with several sunken parts 31 arranged along the length of the water-cooled tank 3 on the side near the base plate 05. The turbulence-dispersing water wheels 4 are rotatably installed in the sunken parts 31 in a corresponding manner. The structural design of the sunken parts 31 ensures that the main body of the turbulence-dispersing water wheels 4 is located below the normal liquid level in the water-cooled tank 3, which not only ensures the turbulence effect during rotation, but also prevents excessive overall liquid level fluctuations, thus avoiding the impact of liquid level fluctuations on the conveying stability of the car seat clip body 01.

[0044] The turbulence impeller 4 includes a shaft 41 and several turbulence plates 42. The shafts 41 are rotatably mounted on the two end side walls of the sinking part 31 in a corresponding manner. Turbulence plates 42 are evenly distributed and fixed on the outer wall of each shaft 41 along the circumference. A small anti-interference gap is left between the outer end of the turbulence plate 42 and the inner wall of the sinking part 31 to maximize the turbulence lifting effect while ensuring smooth rotation.

[0045] The drive mechanism can drive all the turbulence turbines 4 to rotate simultaneously within their corresponding submerged sections 31, thereby creating a continuous surge of liquid surface above each submerged section 31 within the water-cooling tank 3, such as... Figure 7 As shown by the dotted line, the height of the surging liquid level is higher than the top surface of the car seat clip body 01, so that the cooling water can completely cover all the structures of the car seat clip body 01, including the corner gap between the protrusion A013, the protrusion B014 and the plate, thus realizing the immersion water cooling of the car seat clip body 01.

[0046] The structure formed by the sunken part 31 and the turbulent water wheel 4 is arranged in multiple intervals along the length of the water cooling tank 3, which can intermittently immerse the car seat clip body 01 in water cooling, so that the car seat clip body 01 forms a brief temperature homogenization process in the interval between two adjacent sets of surges, so that the temperature of the main body 011, side plate 012 and protrusions A013 and B014 after cooling is further consistent, avoiding secondary imbalance of cooling rate caused by continuous immersion, and further suppressing uneven shrinkage and warping deformation.

[0047] Meanwhile, the intermittent liquid surges can repeatedly flush the surface and corner gaps of the car seat clip body 01, continuously expelling the air bubbles generated by heat exchange and the hot water layer stuck at the interface. This not only enhances the overall heat exchange efficiency but also completely eliminates cooling dead zones. The intermittent turbulence design also avoids large fluctuations in the overall liquid level in the water-cooling tank 3 caused by continuous rotation turbulence, ensuring the stability of the car seat clip body 01 during the conveying process and further improving the consistency and dimensional accuracy of the cooling and shaping of the car seat clip body 01.

[0048] like Figure 5 As shown in one example of this application, two baffles 32 are fixed on the side of the water-cooling tank 3 away from the substrate 05. An immersion water-cooling cavity 06 is formed in the water-cooling tank 3 between the two baffles 32. Both baffles 32 have through-holes 321 of equal height. The car seat clip body 01 passes smoothly through the through-holes 321. At the same time, the inner wall of the through-holes 321 is rounded and blunted to avoid scratching the surface of the car seat clip body 01 during transportation and to ensure the appearance quality of the product.

[0049] After intermittent liquid surface surge cooling, the car seat clip body 01 eventually enters the immersion water cooling chamber 06, as... Figure 8 As shown by the dotted line, the liquid level in the immersion water-cooling cavity 06 is higher than the top surface of the car seat clip body 01, which allows the car seat clip body 01 to be continuously cooled by water immersion in the immersion water-cooling cavity 06, thus completing the final water-cooling shaping.

[0050] The water supply unit is a closed-loop water circulation structure, which includes a water storage tank 9, a water supply pump 91, and a water supply pipe 92, such as Figure 1 , Figure 2 and Figure 5As shown, the water storage tank 9 is located below the end of the water cooling tank 3 away from the substrate 05, and has an opening at the top for receiving the cooling water overflowing from the water cooling tank 3. The inner tube 1 is provided with an upward-facing water collection tank 14 below the end away from the substrate 05. The bottom of the water collection tank 14 is connected to a return water pipe 15, and the other end of the return water pipe 15 is connected to the water storage tank 9 for recycling excess water overflowing from the end of the outer cylinder 2 away from the substrate 05.

[0051] The water supply pump 91 is located at the bottom outlet of the water storage tank 9. One end of the water supply pipe 92 is connected to the water supply pump 91, and the other end is connected to the side of the water cooling tank 3 and communicates with the immersion water cooling cavity 06 to form a complete closed-loop water circulation system.

[0052] Water pump 91 pumps water from storage tank 9 through water supply pipe 92 into immersion water cooling chamber 06. Water in immersion water cooling chamber 06 overflows from one side throughlet 321 back into storage tank 9, and from the other side throughlet 321 into water cooling tank 3 located between substrate 05 and side baffle 32. Finally, water enters inner tube 1 through through hole on substrate 05. Water overflowing from the end of outer cylinder 2 away from substrate 05 falls into water collection tank 14, and finally flows back into storage tank 9 through return water pipe 15.

[0053] The above structure enables the recycling of cooling water, significantly reducing water consumption. At the same time, the water storage tank 9 can be equipped with a filter component (using existing technology, not shown in the figure) and a refrigeration component (using existing technology, not shown in the figure) to filter and remove impurities from the recycled water and control its temperature, ensuring that the supplied cooling water temperature is constant and further improving the stability of cooling.

[0054] Furthermore, the drip cooling unit of this application adopts a self-stabilizing design with overflow water supply from the immersion water cooling chamber 06. The water in the storage area comes directly from the overflow of the immersion water cooling chamber 06, eliminating the need for additional independent water pumps, pipelines, pressure regulating valves, and other components. This simplifies the equipment structure and ensures a constant water level and stable drip pressure in the storage area, guaranteeing that the uniformity of the drip is not affected by fluctuations in the upstream water supply pressure. This design is linked with the overall water circulation system, simultaneously achieving water supply and pressure stabilization.

[0055] In addition, the above mechanism allows the liquid at the dripping hole group 11 to drip down due to natural gravity, avoiding the excessive impact on the car seat clip body 01 caused by the high pressure of the dripping outflow due to the pumping system, which would cause the car seat clip body 01 to bend and deform.

[0056] The drive mechanism adopts a single power source synchronous drive design, which includes a drive motor 51, a rotating shaft 52, and a gear 55, such as... Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a mounting base 5 is fixed to the side of the water cooling tank 3, and a rotating shaft 52 is rotatably mounted on the mounting base 5 along the length of the water cooling tank 3. A drive motor 51 is fixed to the side of the mounting base 5, and its output shaft is fixedly connected to the end of the rotating shaft 52.

[0057] The rotating shaft 52 passes through the base plate 05 and rotates with the base plate 05 through the bearing to ensure the coaxiality and stability of the rotating shaft 52 during rotation. The gear 55 is fixed at the end of the rotating shaft 52 away from the drive motor 51. A toothed ring 56 is coaxially fixed on the side of the outer cylinder 2. The gear 55 and the toothed ring 56 mesh with each other to realize that the rotating shaft 52 drives the outer cylinder 2 to rotate synchronously.

[0058] One end of each shaft 41 extends through to the outside of the recessed portion 31 and is fixedly mounted with a worm gear body 53. A helical portion 54 is provided on the rotating shaft 52 at a position corresponding to each worm gear body 53. The helical portion 54 and the rotating shaft 52 form a worm structure that meshes with each worm gear body 53 to form a worm gear transmission pair.

[0059] When the drive motor 51 is working, its output shaft can drive the entire assembly consisting of the rotating shaft 52, the spiral part 54 and the gear 55 to rotate. Through the worm gear transmission pair, it can drive each turbulent water wheel 4 to rotate. Through the meshing transmission of the gear 55 and the gear ring 56, it can drive the outer cylinder 2 to rotate. This structure allows a single drive motor 51 to simultaneously drive the outer cylinder 2 and all the turbulent water wheels 4 to move synchronously, which not only greatly simplifies the equipment structure, but also reduces manufacturing costs and equipment failure rate.

[0060] like Figure 1 , Figures 9 to 11 As shown, the hot air drying unit includes a drying cylinder 6, a reversing cover 8, a suction pipe 82, and a pair of annular pipes 7. The drying cylinder 6 is located on the downstream discharge side of the water cooling tank 3. The inner cavity of the drying cylinder 6 is the drying channel for the car seat clip body 01, and is aligned with the inlet 321 to ensure that the cooled car seat clip body 01 smoothly enters the drying channel.

[0061] Two annular tubes 7 are fixed to the inner wall of the drying cylinder 6 near the two ends of the axis. Several air nozzles 71 are arranged in a ring around the axis of the drying cylinder 6. All the air nozzles 71 on the same side are clustered and inclined towards one side of the other annular tube 7. That is, the air nozzles 71 at the feed end are inclined towards the discharge end, and the air nozzles 71 at the discharge end are inclined towards the feed end, forming a hot air field that sprays in opposite directions.

[0062] Both annular pipes 7 are connected to air supply pipes 72, which are connected to external hot air blowers to provide a stable hot air source for the drying process.

[0063] The reversing cover 8 is fixed inside the drying cylinder 6 at the center between the two annular tubes 7. Several suction ports 81 that communicate with the interior are evenly distributed on the inner edge wall of the reversing cover 8 around the axis of the drying cylinder 6. One end of the reversing cover 8 is connected to the suction pipe 82, and the other end of the suction pipe 82 is connected to an external industrial vacuum cleaner.

[0064] In the drying process, such as Figure 11 As shown by the dotted arrow, the external hot air blower supplies hot air to the annular pipe 7 through the air supply pipe 72. The hot air is ejected at high speed through the inclined jet nozzle 71. The two sets of opposing jets of hot air converge in the middle of the drying cylinder 6 to form a hot air field that completely surrounds the car seat clip body 01, which can thoroughly blow away residual water droplets on the surface of the car seat clip body 01, including the corner gaps.

[0065] The industrial vacuum cleaner creates negative pressure through the suction pipe 82 and suction port 81, which promptly draws the hot and humid air carrying water droplets out of the drying cylinder 6, achieving directional flow of hot air and avoiding the decrease in drying effect caused by the circulation of hot and humid air in the drying cylinder 6. This completely solves the problem of oxidation and discoloration caused by water stains on the surface of the car seat clip body 01, ensuring the appearance quality of the product. At the same time, the hot air can be recycled after dehumidification and heating, reducing production energy consumption.

[0066] In addition, the synergistic effect of the aforementioned opposing converging hot air field and the central annular negative pressure suction also serves to remove impurities from the surface of the car seat clip body 01, as detailed below: After the two hot air streams collide, they form a high-speed, wall-adhering flow along the irregular cross-sectional contour of the clip, enveloping the main body 011, side plate 012, and the protruding clip structure. The shearing force generated by the airflow on the profile surface can directly peel off loose impurities such as dust, scale particles, and low-molecular-weight precipitates attached to the plane. At the same time, the wall-adhering flow can flow along the corner gaps between the clip and the plate, breaking the static flow field in the gaps and directly impacting the residual molten flash and debris in the gaps, achieving mechanical removal of impurities without dead angles.

[0067] In addition, after the opposing high-speed airflows collide, a high-intensity turbulent field is formed around the clip, breaking the adhesion between impurities and the profile; at the same time, the hot air simultaneously heats and evaporates the water film on the surface, allowing the impurities to completely lose their bonding carrier, detach from the profile surface and suspend in the airflow, creating favorable conditions for impurity removal.

[0068] Unlike traditional unidirectional flow systems that only blow impurities toward the discharge end or even get stuck deep in the gaps, the two sets of opposing airflows combined with the negative pressure suction airflow in the middle have a strong ability to peel off impurities stuck deep in the gaps, avoiding secondary adhesion of impurities. Moreover, the impurity removal and drying mechanism does not come into contact with the car seat clip body 01 throughout the entire process, avoiding scratches on the surface of the car seat clip body 01.

[0069] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
