Description

Technical Field

[0001] This utility model relates to the field of component cooling, and in particular to the field of paint drying technology, specifically a rapid cooling and drying device for threaded sleeve paint. Background Technology

[0002] In the surface treatment process of threaded sleeves, there is a significant technical shortcoming in the cooling process after paint drying. The current process is as follows: First, the painted threaded sleeve is placed in a 140℃ oven and heated for half an hour to complete the curing. Then, it is transferred to an open cooling workbench and forced to cool by ordinary electric fans. After it has completely cooled and the paint is dry, it is poured into a turnover box.

[0003] This traditional method has the following drawbacks:

[0004] (1) Low space utilization. The cooling platform occupies a large area, but can only hold 6 baskets of workpieces at a time. The working area and the material turnover space are squeezed against each other.

[0005] (2) The cooling efficiency bottleneck is prominent, and the 30-minute cooling time for a single batch causes a delay in the production line cycle time;

[0006] (3) The open structure of the cooling table makes the effective utilization rate of the electric fan airflow less than 40%, a large amount of wind energy is lost, the wind force is dispersed and not concentrated, and the cooling time is long.

[0007] (4) Environmental pollutants spread, and volatile organic compounds (VOCs) diffuse throughout the paint spraying workshop under the influence of disordered airflow, resulting in a strong and pungent smell of paint.

[0008] A prior art patent (CN114367426A) discloses an integrated heating and cooling device for screw gluing that can be used with a conveyor belt. The device includes a top plate and a housing. Support plates are bolted to both sides of the bottom of the top plate. A housing is bolted to the front of the opposite side of the support plates. A cooling mechanism is installed inside the housing, and a drying mechanism is installed inside the housing. A first through-slot is formed on the opposite side of the housing, and second through-slots are formed on both the front and back of the housing. A first motor and a rotating... The cooperation of the disc, the first moving plate, the rack plate, the fixed gear, the rotating rod, the second moving plate, the cold air fan, and the first connecting frame improves the cooling effect of the screws, allowing the dried screws to cool down quickly, which facilitates subsequent processing and storage. The second motor, the rotating shaft, the driving gear, the driven gear, the lead screw, the threaded sleeve, the fixed fan, the heating box, the tee pipe, and the second connecting frame further improve the drying effect of the screws, allowing the adhesive to solidify quickly. Although both are used for drying screw threaded sleeve products, the structure is relatively complex and includes a conveyor structure; the screw structure is driven by a conveyor belt, which is different from the technical solution in this case.

[0009] A prior art patent (CN208853190U) discloses a decorative wood panel paint drying device. The device includes a hydraulic cylinder at the bottom of one inner wall of the drying chamber for guiding a placement seat through a roller shutter door. The placement seat is mounted on the hydraulic cylinder, and a rotating shaft between the placement seat and the hydraulic cylinder allows the placement seat to rotate vertically. A support plate has several ventilation holes evenly distributed, and parallel partitions are evenly distributed on its upper surface. A spiral wind channel is spirally arranged on the inner wall of the drying chamber to guide the direction of hot airflow. Several air inlets are evenly distributed at the bottom of the drying chamber, and the spray direction of the air inlets matches the spiral wind channel. A visual fluorescent formaldehyde sensor is installed inside the drying chamber. This invention offers high drying efficiency and easy cleaning. Although it is used for drying products, the object is wood paneling, not threaded sleeves. While it discloses a waste gas collection structure, it focuses on formaldehyde collection and does not provide purification or emission reduction.

[0010] Existing technology discloses a spray-painted parts drying oven (patent number CN221288579U), which not only purifies the waste gas generated during drying, preventing it from polluting the environment and affecting employee health, but also reuses the heat in the waste gas, improving thermal efficiency and reducing energy loss. It includes a furnace body structure, a hook mechanism, a heating mechanism, a conveying mechanism, a recovery mechanism, and a purification mechanism. The hook mechanism is installed on the furnace body structure to facilitate hanging the spray-painted parts, the heating mechanism is installed on the furnace body structure to heat the air, the conveying mechanism is installed on the furnace body structure to transport the hot air into the drying oven, the recovery mechanism is installed on the furnace body structure to collect the waste gas in the drying oven, and the purification mechanism is installed on the furnace body structure to treat the waste gas. Although this technology discloses a drying device integrating heating, drying, and waste gas recovery, its product holding unit is a hook structure, which differs from this technical solution; moreover, the dust collection drawer and shelf structure are not disclosed. Summary of the Invention

[0011] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a rapid cooling and drying device for threaded sleeve paint, so as to solve the difficulties of the prior art.

[0012] To achieve the above and other related objectives, this utility model provides a rapid cooling and drying device for threaded sleeve paint, comprising:

[0013] The outer casing 1 has a double door on the front and openings at the top and bottom;

[0014] Guide bracket 2, multiple sets of guide brackets 2 for guiding and loading the threaded sleeve product basket are arranged inside the outer shell body 1;

[0015] An air outlet filter unit is installed on the top of the outer shell 1, and a second high-power fan 4 is installed inside the air outlet filter unit.

[0016] A high-power fan 3 with an upward airflow direction is installed inside the lower part of the outer casing 1;

[0017] A dust collection drawer 5 is provided inside the outer casing 1, below the No. 1 high-power fan 3, and is a push-pull dust collection drawer 5.

[0018] Furthermore, the airflow direction of the No. 1 high-power fan 3 and the No. 2 high-power fan 4 is the same, both facing the upward air outlet filter unit.

[0019] In this technical solution, for efficient cooling of the threaded sleeve product after high-temperature curing, a dual-fan system combining bottom active air supply and top suction is used in this embodiment. The product basket is positioned and guided using guide bracket 2 to optimize the airflow path, achieving concentrated and efficient delivery of cooling airflow, significantly improving the cooling rate and uniformity. At the same time, a push-pull dust collection drawer is set at the bottom for easy cleaning of residual impurities, quickly completing dust collection and improving equipment maintenance efficiency. In addition, an integrated exhaust filter unit at the top can effectively remove harmful gases during the cooling process and improve the air quality in the workshop.

[0020] According to the preferred embodiment, a pair of guide brackets 2 are symmetrically arranged, and the opening of the pair of guide brackets 2 is larger on the side closer to the double doors.

[0021] Furthermore, the guide support 2 is provided with an upper and lower two-layer structure.

[0022] In this technical solution, the guide bracket 2 is designed as a two-layer structure, with each layer consisting of two symmetrically arranged guide brackets 2. The opening on the side closer to the double doors is larger to facilitate the smooth introduction of the product basket from the double doors and its sliding positioning along the guide bracket 2 to the designated position inside the outer shell 1. This significantly improves the ease of operation and positioning accuracy when introducing the product basket, avoids jamming caused by misalignment, and enhances the overall efficiency and safety of the equipment.

[0023] According to the preferred embodiment, a gap is left between the guide bracket 2 and the left and right inner sides of the outer shell body 1.

[0024] In this technical solution, by setting a gap between the guide bracket 2 and the left and right inner sides of the outer shell 1, the product basket has better ventilation performance during the air drying process. Airflow can flow in the gap, avoiding the impact of local air pressure changes on the overall airflow circulation efficiency. At the same time, this structure can also reduce heat conduction between the guide bracket 2 and the outer shell 1, reduce the risk of surface temperature rise of the outer shell 1, and improve operational safety.

[0025] According to the preferred embodiment, a guide plate 6 is installed at the bottom of the upper guide bracket 2. One end of the guide plate 6 is fixed to the guide bracket 2, and the other end extends downward and is fixed to the inner wall of the outer shell body 1.

[0026] In this technical solution, when the product located on the upper guide bracket 2 is air-dried, the airflow at the bottom can be guided by the guide plate 6 to flow in a set direction. The airflow of the No. 1 high-power fan 3 is weakened after passing through the product on the lower guide bracket 2. Then, the airflow is concentrated by the guide plate 6 and passes through the middle of the upper guide bracket 2, which concentrates the airflow, increases the air speed, and greatly improves the cooling efficiency.

[0027] According to the preferred design, the No. 1 high-power fan 3 is installed below the lower guide bracket 2.

[0028] Furthermore, the blades of the No. 1 high-power fan 3 are coated with an anti-static coating.

[0029] In this technical solution, the No. 1 high-power fan 3 is installed below the lower guide bracket 2, so that the airflow generated by the No. 1 high-power fan 3 will not directly interfere with the positioning and introduction process of the product basket in the guide bracket 2, and at the same time it is more conducive to the airflow rising evenly from the bottom, improving the overall airflow circulation efficiency.

[0030] In addition, by coating the blades of the No. 1 high-power fan 3 with an anti-static coating, the accumulation of static electricity caused by airflow friction during fan operation is effectively suppressed, thereby avoiding the adsorption or damage of static electricity to the threaded sleeve products in the product basket, and improving the stability of the equipment in high dust environments and the safety of product handling.

[0031] According to the preferred embodiment, the air outlet filter unit includes an air collecting hood 7 and a filter flue 8 arranged sequentially on the top of the outer casing 1, and a second high-power fan 4 is installed at the inlet of the air collecting hood 7.

[0032] The smoke outlet direction of the filter flue 8 is different from that of the air collection hood 7.

[0033] Furthermore, the smoke outlet direction of the filter flue 8 is perpendicular to the smoke outlet direction of the air collecting hood 7.

[0034] In this technical solution, the top of the outer casing 1, in the direction of smoke outlet, is fixedly installed with a second high-power fan 4's air collection hood 7 and a filter duct 8;

[0035] The exhaust direction of the filter flue 8 is perpendicular to the exhaust direction of the air collector hood 7, forming a horizontal exhaust path. While utilizing the filter flue 8 to adsorb harmful gases volatilized during the cooling process, it prevents hot air and odors from flowing back into the equipment, thus improving the air circulation quality during equipment operation.

[0036] According to the preferred embodiment, the air collecting hood 7 adopts a flared structure, the air inlet of the air collecting hood 7 is connected to the top opening of the outer shell body 1, and the air outlet is connected to the filter flue 8 through a flange.

[0037] In this technical solution, by designing the air collecting hood 7 as a flared horn structure and using a flange connection to combine it with the filter flue 8, the uniformity and flow efficiency of the airflow entering the filter flue 8 are improved, thereby enhancing the overall purification capacity of dust collection. At the same time, it is easy to disassemble and maintain, improving the stability and practicality of the equipment.

[0038] According to the preferred embodiment, a removable metal filter is provided at the bottom of the air collector shroud 7, and the metal filter is located below the second high-power fan 4.

[0039] In this technical solution, the metal filter screen can be used to intercept large particulate impurities that rise with the hot airflow, preventing impurities from entering the filter flue and causing blockage or reducing the purification efficiency of the activated carbon exhaust gas treatment device. The metal filter screen is fixed to the inner wall of the air collection hood by a snap-fit ​​structure, which is convenient for regular disassembly, cleaning or replacement.

[0040] According to the preferred scheme, the filter flue 8 is equipped with an activated carbon waste gas treatment device.

[0041] Furthermore, the activated carbon waste gas treatment device has a honeycomb-shaped granular activated carbon filling structure.

[0042] In this technical solution, the filter flue 8 is equipped with an activated carbon exhaust gas treatment device. The activated carbon exhaust gas treatment device is a filter cavity filled with honeycomb-shaped activated carbon. The honeycomb activated carbon can effectively enhance the ability to adsorb residual harmful gases and volatile organic compounds in the airflow, thereby improving the overall purification efficiency.

[0043] According to the preferred embodiment, the dust collection drawer 5 is equipped with a metal filter and an electrostatic dust removal module.

[0044] In this technical solution, the metal filter and electrostatic dust removal module can improve dust collection efficiency, especially for fine particles, thus improving the overall dust removal performance. At the same time, the electrostatic dust removal module 13 is reusable, reducing maintenance frequency and operating costs.

[0045] This invention addresses the efficient cooling of threaded sleeve products after high-temperature curing. A dual-fan system, combining bottom-mounted active airflow and top-mounted suction, with a baffle plate optimizing the airflow path, achieves concentrated and efficient cooling air delivery, significantly improving cooling rate and uniformity. Furthermore, an integrated top-mounted exhaust filter unit and activated carbon waste gas treatment device effectively remove harmful gases, improving workshop air quality. A dust collection drawer facilitates cleaning of paint residue and dust, enhancing maintenance efficiency. The overall structure is compact, with high space utilization, and adaptable to the production needs of drying multiple sets of threaded sleeves.

[0064] This utility model proposes a rapid cooling and drying device for threaded sleeve paint, which is used in the drying process of threaded sleeves. This utility model does not limit the type of threaded sleeve, but the structure of the rapid cooling and drying device for threaded sleeve paint is particularly suitable for the drying needs of threaded sleeves for automotive parts.

[0065] In general, the threaded sleeve paint rapid cooling and drying equipment proposed in this utility model mainly includes a housing body 1, a guide bracket 2, an air outlet filter unit, a high-power fan 3, and a dust collection drawer 5. See also... Figure 1 It shows the arrangement of the outer casing 1, guide bracket 2, air outlet filter unit, high-power fan 3, and dust collection drawer 5.

[0066] To achieve rapid cooling and air drying of threaded sleeves without environmental pollution, this paper addresses the following shortcomings of traditional methods in the background art: low space utilization (the cooling table occupies a large area but can only hold 6 baskets of workpieces at a time, resulting in a squeeze between the work area and material handling space); significant bottleneck in cooling efficiency (the 30-minute cooling time per batch causes production line delays); the open structure of the cooling table results in less than 40% effective utilization of the electric fan airflow, leading to significant energy loss, dispersed and unfocused airflow, and prolonged cooling time; and the diffusion of environmental pollutants, with volatile organic compounds (VOCs) spreading throughout the paint shop under the influence of disordered airflow, causing a pervasive and pungent paint odor. Therefore... In the technical solution provided in this embodiment, for the efficient cooling of threaded sleeve products after high-temperature curing, a dual-fan system combining bottom active air supply and top suction is used, along with a guide plate to optimize the airflow path, thereby achieving concentrated and efficient delivery of cooling airflow and significantly improving the cooling rate and uniformity. In addition, an integrated exhaust filter unit at the top and an activated carbon waste gas treatment device effectively remove harmful gases and improve the air quality in the workshop. The dust collection drawer facilitates the cleaning of paint residue and dust, improving maintenance efficiency. The overall structure is compact, with high space utilization, and is suitable for the production needs of drying multiple sets of threaded sleeves.

[0067] Specifically, in this embodiment, the top and bottom of the outer shell 1 are open structures, and the front is provided with a double door, which facilitates the simultaneous loading of 12 or more threaded sleeve products in the upper and lower layers for charging and drying. In order to achieve stable support for the load of threaded sleeve products, multiple sets of guide brackets 2 for guiding the load of threaded sleeve products are provided inside the outer shell 1. In this embodiment, the guide brackets 2 are provided as a two-layer structure, and each layer consists of two symmetrically arranged guide brackets 2. The guide brackets 2, together with the horizontal frame of the outer shell 1 near the double door, can achieve the purpose of supporting six sets of product baskets in a row in each set of guide brackets 2.

[0068] Furthermore, in order to achieve more convenient and stable rapid insertion and ejection of the threaded sleeve product basket, the guide bracket 2 has a larger opening on the side near the double doors, so that the product basket can be smoothly introduced from the side of the double doors and slidably positioned along the guide bracket 2 to the designated position inside the outer shell 1. This significantly improves the ease of operation and positioning accuracy when the product basket is introduced, avoids jamming caused by poor alignment, and improves the overall efficiency and safety of the equipment.

[0069] In addition, the product basket has better ventilation performance during the air drying process. There is a gap between the guide bracket 2 and the left and right inner sides of the outer shell 1, and the airflow can flow in the gap to avoid the overall airflow circulation efficiency being affected by local air pressure changes. At the same time, this structure can also reduce heat conduction between the guide bracket 2 and the outer shell 1, reduce the risk of the surface temperature of the outer shell 1 rising, and improve operational safety.

[0070] Based on this, since the outer shell 1 is equipped with two rows of guide brackets 2, that is, two rows of threaded sleeves with drying functions, the threaded sleeves at the bottom are directly affected by the high-power fan 3 below during the drying process. However, the airflow to the threaded sleeves at the top is obstructed. Therefore, a guide plate 6 is installed at the bottom of the upper guide bracket 2. One end of the guide plate 6 is fixed to the guide bracket 2, and the other end extends downward and is fixed to the inner wall of the outer shell 1. When the product on the upper guide bracket 2 is dried, the airflow at the bottom can be guided by the guide plate 6 to flow in a set direction. The airflow of the high-power fan 3 is weakened after passing through the product on the lower guide bracket 2. Then, the airflow is concentrated by the guide plate 6 and passes through the middle of the upper guide bracket 2, which concentrates the airflow, increases the air speed, and greatly improves the cooling efficiency.

[0071] As mentioned above, this embodiment provides a dual-fan system. On the one hand, a high-power fan 3 with the airflow direction facing upward is installed inside the lower part of the outer casing 1. On the other hand, an air outlet filter unit is installed on the top of the outer casing 1, and a second high-power fan 4 is installed inside the air outlet filter unit.

[0072] Based on this, the No. 1 high-power fan 3 is installed below the lower guide bracket 2, so that the airflow generated by the No. 1 high-power fan 3 will not directly interfere with the positioning and introduction process of the product basket in the guide bracket 2. At the same time, it is more conducive to the airflow rising evenly from the bottom, improving the overall airflow circulation efficiency. In addition, by coating the blade surface of the No. 1 high-power fan 3 with an anti-static coating, the accumulation of static electricity caused by airflow friction during fan operation is effectively suppressed, thereby avoiding the adsorption or damage of static electricity to the threaded products in the product basket, improving the stability of the equipment in high dust environment and the safety of product handling.

[0073] Meanwhile, regarding the second high-power fan 4, a more detailed explanation is provided: the air outlet filtration unit includes an air collecting hood 7 and a filter flue 8 sequentially arranged on the top of the outer casing 1. The second high-power fan 4 is installed at the inlet of the air collecting hood 7. The air collecting hood 7 adopts a trumpet-shaped flared structure. The air inlet of the air collecting hood 7 is connected to the opening at the top of the outer casing 1, and the air outlet is connected to the filter flue 8 through a flange. By designing the air collecting hood 7 as a trumpet-shaped flared structure and using a flange connection to combine it with the filter flue 8, the uniformity and flow efficiency of the airflow entering the filter flue 8 are improved, thereby enhancing the overall purification capacity of dust collection. At the same time, it is easy to disassemble and maintain, improving the stability and practicality of the equipment.

[0074] In addition, the metal filter screen can be used to intercept large particulate impurities that rise with the hot airflow, preventing impurities from entering the filter flue and causing blockage or reducing the purification efficiency of the activated carbon exhaust gas treatment device. The metal filter screen is fixed to the inner wall of the air collection hood by a snap-fit ​​structure, which is convenient for regular disassembly, cleaning or replacement.

[0075] Furthermore, in order to improve the air circulation quality during equipment operation, a high-power fan 4 is fixedly installed in sequence on the top of the outer casing 1 along the smoke outlet direction, forming a horizontal exhaust path. This changes the smoke outlet direction of the filter flue 8 to be perpendicular to the smoke outlet direction of the air collector 7. By using the filter flue 8 to adsorb harmful gases volatilized during the cooling process, the backflow of hot air and odors into the equipment is prevented.

[0076] It should be specifically noted that the filter flue 8 is equipped with an activated carbon exhaust gas treatment device. The activated carbon exhaust gas treatment device has a honeycomb-shaped granular activated carbon filling structure. The filter flue 8 is equipped with an activated carbon exhaust gas treatment device. The activated carbon exhaust gas treatment device is filled with a filter cavity with honeycomb-shaped activated carbon. The honeycomb activated carbon can effectively enhance the ability to adsorb residual harmful gases and volatile organic compounds in the airflow, thereby improving the overall purification efficiency.

[0077] Similarly, the dust collection drawer 5 is equipped with a metal filter and an electrostatic dust removal module. The metal filter and electrostatic dust removal module can improve dust collection efficiency, especially for fine particles, which has a stronger adsorption capacity and improves the overall dust removal performance. At the same time, the electrostatic dust removal module 13 can be reused, reducing the maintenance frequency and operating costs.

[0078] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
