Description

Technical Field

[0001] This utility model relates to the field of automotive parts drying technology, specifically a drying device for automotive parts production and processing. Background Technology

[0002] In the field of automotive parts manufacturing and processing, the drying process is of paramount importance. However, traditional automotive parts drying methods have many drawbacks and are difficult to meet the stringent requirements of modern automotive production for high efficiency and high quality.

[0003] Traditional drying equipment uses a very simple hot air jet method, often only supplying heat from the top or side. This results in severely uneven heating of automotive parts, with some areas unable to obtain sufficient heat, leading to significantly longer drying times and extremely low overall efficiency. Moreover, since it is impossible to achieve all-round drying, it is often necessary to frequently adjust the position of the parts or repeat the drying operation, which undoubtedly further increases production time and costs.

[0004] Traditional tunnel oven drying equipment generally lacks an effective way to observe the internal condition in real time. Operators find it difficult to accurately grasp the state of automotive parts during the drying process and cannot adjust the drying parameters in a timely manner according to the actual situation. This can easily lead to over-drying or under-drying. Over-drying may damage the performance of the parts, causing them to deform or become brittle; under-drying will affect subsequent processing procedures and product quality, such as causing the coating adhesion to decline and the assembly accuracy to decrease.

[0005] Because traditional drying methods struggle to achieve uniform heating, uneven heating is a common problem for automotive parts during the drying process. Overheating in some areas can cause parts to deform, crack, or become damaged, while underheated areas may retain moisture or other impurities, severely impacting the quality and lifespan of the parts. This not only increases the scrap rate but also raises production costs, negatively affecting the overall quality and reliability of the vehicle. Utility Model Content

[0020] 3. Preventing gas leakage: In the sluice assembly, a rubber curtain is installed inside the ventilated sluice to ensure that there is no gas leakage in the area where the side nozzles are not located, and that gas can still be delivered in the area where the side nozzles are located due to the support of the connecting parts; in the side spray assembly, the top curtain is set so that the soft curtain of the ventilated sluice folds inward to better prevent gas overflow. These designs effectively reduce hot gas leakage and improve energy utilization efficiency.

[0021] 4. Precise drying operation: A transparent observation window is set on the front surface of the tunnel oven, which allows for real-time observation of the internal conditions of the tunnel oven.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-4This utility model provides a drying technology solution for automotive parts: a drying device for automotive parts production and processing, including a tunnel furnace 1, support members 3, rotating wheels 4, and a conveyor belt 5. Support members 3 are provided on both the left and right sides of the tunnel furnace 1. The support members 3 bear the weight of the rotating wheels 4 and provide support force to the rotating wheels 4. The rotating wheels 4 are provided on the inner side of the support members 3. When rotating, they can drive the conveyor belt 5 to move. The rotating wheels 4 are connected to the conveyor belt 5. The objects at the top driven by the rotating wheels 4 will be transported from right to left by the conveyor belt 4. A transparent observation window 2 is provided on the front surface of the tunnel furnace 1 for real-time observation of the interior of the tunnel furnace to complete the precise drying work.

[0035] A high-pressure jet assembly is installed on the right side of the tunnel furnace 1. This assembly releases high-pressure jets onto the automotive parts before they enter the furnace, blowing off any water adhering to their surface. A gas delivery pipe 13 is located at the top of the tunnel furnace 1, transmitting gas to various top jet nozzles 14 and sliding delivery pipes 15, primarily serving to transport hot gas. Multiple top jet nozzles 14 are located at the bottom of the gas delivery pipe 13, spraying hot gas from top to bottom to dry the automotive parts. Sliding delivery pipes 15 are located on both the front and rear sides of the bottom of the gas delivery pipe 13, receiving the hot gas and simultaneously transferring it to… The side nozzles and the slide pipe 15 are provided with a slide assembly on the side near the conveyor belt 5. The side nozzles 18 slide on the outer wall of the slide pipe 15 to dry the automotive parts from multiple directions, which can make the automotive parts heat more evenly. The slide pipe 15 is provided with a side nozzle assembly, which can be used to slide on the outer wall of the slide pipe (15) to dry the automotive parts from all directions. It can also make the automotive parts heat more evenly to prevent the workpiece from being damaged due to uneven heating or overheating in some areas. The top of the tunnel furnace 1 is provided with a motor 25, which can generate power to transmit power to the entire machine.

[0036] Specifically, the high-pressure jet assembly includes a connector 6, which is located on the left side of the tunnel furnace 1 and is used to connect the high-pressure jet assembly and the gas delivery pipe 13, enabling the high-pressure jet assembly to eject high-pressure hot gas. A straight pipe 7 is provided at the bottom end of the connector 6, used to connect the top connector 6 and the bottom first rotary joint 8. The first rotary joint 8 is provided on the outer wall of the bottom end of the straight pipe 7, allowing a first bent pipe 9 to rotate at the bottom end of the straight pipe 7 via the first rotary joint 8. A first bent pipe 9 is provided on the inner wall of the bottom end of the first rotary joint 8, used to connect the top... The first rotary joint 8 at one end and the second rotary joint 10 at the bottom end are provided. The second rotary joint 10 is provided on the outer wall of the bottom end of the first bent pipe 9 to ensure that the second bent pipe 11 can rotate at the bottom end of the first bent pipe 9 through the second rotary joint. The inner wall of the second rotary joint 10 is provided with the second bent pipe 11 for connecting the second rotary joint 10 and the air nozzle. The bottom end of the second bent pipe 11 is provided with the air nozzle 12, which can spray high-pressure hot air to clean the water adhering to the surface of the automotive parts, thus making subsequent drying more convenient.

[0037] The first bend 9 can rotate at the bottom end of the straight pipe 7 via the first rotary joint 8, while the bend 11 can rotate at the bottom end of the first bend 9 via the second rotary joint 10. The cooperation between the bend and the rotary joint enables the nozzle 10 to clean automotive parts in various directions, and thus it can also be used for automotive parts of various shapes.

[0038] The connector 6 passes through the tunnel furnace 1 and is interconnected with the gas supply pipe 13, so as to ensure that the gas supply pipe 13 can input gas into the high-pressure jet assembly.

[0039] More specifically, the slide assembly includes a slide 16, which is disposed on the left and right sides of the slide pipe 15 near the conveyor belt 5 to limit the sliding trajectory of the follower wheel 23. A ventilation slide 17 is provided on the inner side of the slide 16, which can limit the sliding trajectory of the side nozzle 18 while supplying air to the connector side nozzle 18.

[0040] The ventilation duct 17 is equipped with a rubber curtain inside. The rubber curtain can prevent air leakage in the position where the side nozzle 18 is not located. If the side nozzle 18 is located, air can still be supplied to the side nozzle 18 due to the support of the connector 19.

[0041] More specifically, the side spray assembly includes a side spray nozzle 18, which is located on the side of the slide pipe 15 near the conveyor belt 5. The side spray nozzle 18 is used to spray hot air onto the automotive parts for drying. A connector 19 is provided inside the ventilation slide 17. Due to its internal cavity characteristics, gas can be input from the slide pipe 15 to the side spray nozzle 18. A limiting member 20 is provided on the side of the connector 19 near the slide pipe 15. The connector 19, in conjunction with the side spray nozzle 18, allows the side spray nozzle 18 to slide better on the ventilation slide 17. A fixing member 21 is provided on the side of the slide pipe 15 near the 8, which is used to fix the drive wheel 22 and the side nozzle 18. The drive wheel 22 is provided on the inner side of the fixing member 21, which can drive the side nozzle 18 to slide on the outer wall of the slide pipe 15 to perform multi-directional jet drying of the automotive parts. The inner wall of the slide 16 is provided with a follower wheel 23, which is used in conjunction with the drive wheel 22. The upper and lower ends of the connector 19 are provided with top curtain members 24, which make the soft curtain of the ventilation slide 17 fold inward, which can better prevent gas from overflowing.

[0042] The limiting member 20 is disposed inside the slide pipe 15. The limiting member 20 is connected to the side nozzle 18 through the connector 19. The left and right lengths of the limiting member 20 are greater than the width of the ventilation slide 17. This allows the side nozzle 18 to draw gas from the slide pipe 15 and slide better on the outer wall of the slide pipe 15.

[0043] The back of the slide pipe 15 is provided with a slide for the drive wheel 22 to slide. It is used in conjunction with the drive wheel 22 to limit the movement trajectory of the drive wheel 22 and prevent the drive wheel 22 from deviating.

[0044] The length of the top curtain 24 is greater than the distance between the side nozzle 18 and the rubber soft curtain of the ventilation slide 17, so that the soft curtain of the ventilation slide 17 folds inward, which can better prevent gas from overflowing.

[0045] Working principle: When car parts need to be dried, the machine is first adjusted according to the shape and appearance of the car parts. The position of the two air nozzles 12 is adjusted by the cooperation between the straight pipe 7, the first rotary joint 8, the first bent pipe 9, the second rotary joint 10 and the second bent pipe 11. When the car parts pass through the air nozzles 12, the air nozzles 12 will spray high-pressure gas onto them, thereby initially cleaning the water adhering to the surface of the car parts.

[0046] In addition, the orientation of the side nozzle 18 needs to be adjusted. By controlling the drive wheel 22 to rotate in the slide on the back of the slide pipe 15, it drives the side nozzle 18 to slide inside the ventilation slide 17 via the fixing member 21. Due to the cooperation of the slide 16 and the follower wheel 23, this sliding becomes more stable. When the side nozzle 18 slides, the top curtain member 24 will first contact the rubber soft curtain of the ventilation slide 17, and the connecting member 19 will be connected. This method is to reduce the friction between the connecting member 19 and the rubber soft curtain, thereby making the sliding... The movement is smoother. Furthermore, the soft curtain is pushed inward by the top curtain 24, making it less likely for the gas inside the slide pipe 15 to leak outward. However, any slight leakage at the edge of the connector 19 will be blocked by the side nozzle 18, thus not affecting the drying process. When the side nozzle 18 slides, the other end of the connector 19 is connected to the limiting member 20, which also provides some control over the soft curtain. The main function of the limiting member 20 is to restrict the movement trajectory of the side nozzle 18 and prevent the side nozzle 18 from tilting uncontrollably.

[0047] After adjusting the position of the side nozzle 18, the motor 25 can be started to drive the tunnel furnace 1 and the internal components to dry the automotive parts.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
