Description

Technical Field

[0001] This utility model relates to the technical field of aluminum product drying, specifically to a drying device for aluminum product processing. Background Technology

[0002] During the manufacturing process, such as extrusion, stamping, cutting, grinding and polishing, aluminum products will be contaminated with various pollutants, such as process grease, metal particles, polishing compounds, natural oxide layer, fingerprints and dust. Therefore, aluminum products will be cleaned after processing.

[0003] Residual moisture on the surface after cleaning can cause a series of problems, such as water stains and water spots. After the water evaporates, the dissolved minerals in the water remain on the surface, forming white or gray spots and streaks; residual moisture acts as a carrier of electrolytes, and if it contains impurities such as chloride ions, it can form micro-batteries on the aluminum surface, accelerating pitting corrosion; moisture is difficult to drain naturally in threaded holes, riveting joints, and component gaps, and long-term accumulation can lead to severe localized corrosion; if there is moisture on the surface, it will dilute the concentration of the electrolytic cell, resulting in uneven oxide film thickness, inconsistent color, insufficient hardness, or defects.

[0004] Tunnel oven dryers are commonly used drying equipment. There are standalone tunnel oven dryers as well as integrated cleaning and drying equipment. The main differences lie in the cleaning and drying efficiency and equipment cost. Because there are cost issues in replacing equipment, standalone tunnel oven dryers are relatively more widely used.

[0005] Chinese patent application CN201911195410.5, entitled "A Tunnel Oven for High-Efficiency Drying," discloses a tunnel oven for high-efficiency drying. Its main structure is similar to common tunnel ovens, including a conveyor belt, related drive equipment, and an oven. The process involves placing parts on the conveyor belt, manually smoothing the aluminum products to prevent accumulation, and then the conveyor belt transports the aluminum products into the oven for drying. However, aluminum products generally have various shapes and sharp corners; smoothing them directly by hand can cause hand injuries. Therefore, a drying device for aluminum product processing needs to be designed. Utility Model Content

[0006] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problem of hand injuries caused by smoothing parts in the prior art.

[0007] To achieve the above objectives, this utility model provides a drying device for aluminum product processing, including a tunnel furnace dryer body with a conveyor belt, and further including: a smoothing unit mounted on the feeding end of the tunnel furnace dryer body, the smoothing unit including a rotating shaft mounted on the feeding end of the tunnel furnace dryer body via a pair of bearing seats and located above the conveyor belt, a pair of adjusting disc mechanisms symmetrically mounted on both ends of the rotating shaft, a plurality of smoothing rods parallel to the rotating shaft and distributed at intervals along the circumferential direction of the rotating shaft and respectively adjustable at both ends and mounted on the adjusting disc mechanisms, and a drive mechanism for driving the rotating shaft to rotate, wherein the length direction of the smoothing rods is perpendicular to the conveying direction of the conveyor belt.

[0008] Preferably, the adjusting disc mechanism includes a mounting disc fixedly sleeved on the end of the rotating shaft along a coaxial line, a mounting sleeve sleeved on the outside of the rotating shaft and fixedly connected to the mounting disc, an adjusting disc rotatably mounted on the mounting sleeve along a coaxial line, and several sets of sliding mechanisms spaced along the circumferential direction of the mounting disc and slidably mounted on the mounting disc along the corresponding radial direction of the mounting disc. The mounting sleeve has a protruding flange, and a hexagonal pressure plate is threaded onto the end of the mounting sleeve. The two ends of the handle are respectively mounted on corresponding sliding mechanisms. Each sliding mechanism is equipped with a first pulley. The adjusting disc has several arc-shaped grooves spaced along the circumferential direction off-axis. The first pulleys slide into the corresponding arc-shaped grooves.

[0009] Preferably, the sliding mechanism includes a mounting base slidably connected to the mounting plate, a second pulley slidably connected to the mounting base along the sliding direction of the mounting base and connected to the end of the handle, a transmission plate slidably connected to the mounting base along the sliding direction of the mounting base and capable of contacting the side of the second pulley near the axis of the mounting plate, and a spring mounted on the mounting base and abutting against the side of the transmission plate away from the second pulley, wherein the first pulley is mounted on the mounting base.

[0010] Preferably, the drive mechanism includes a motor mounted on the feed end of the tunnel oven dryer body via a mounting bracket, a pair of synchronous pulleys respectively fixedly sleeved on the end of the rotating shaft and the output shaft of the motor, and a synchronous belt that is drively connected to the pair of synchronous pulleys.

[0011] Preferably, the dial on the adjustment plate has a handle.

[0012] Preferably, a guide rod that slides through the mounting base is fixedly mounted on the side of the transfer plate away from the second pulley, the length direction of the guide rod is consistent with the sliding direction of the second pulley, and the spring is sleeved on the guide rod.

[0013] According to the above technical solution, the drying device for aluminum product processing provided by this utility model has the following beneficial effects during use: Firstly, the conveyor belt will carry the aluminum products through the smoothing unit. The rotating shaft drives several smoothing rods to rotate through a pair of adjusting disc mechanisms. The smoothing rods will intercept the aluminum products on the upper layer. At this time, the conveyor belt will still carry the aluminum products on the lower layer to continue moving. This can control the stacking height of the aluminum products and prevent several aluminum products from piling up together, which would cause the internal aluminum products to not be dried. This ensures high safety in use. Secondly, the rotating shaft can drive the guide rod to rotate. If the guide rod is fixed at a certain height, it is easy for aluminum products to get stuck. By driving several guide rods to rotate through the rotating shaft, the stacking height of aluminum products can be controlled, and the problem of jamming can be avoided, as well as damaging friction between the guide rod and the aluminum products. Thirdly, the position of the guide bar on the adjustment plate mechanism can be adjusted to regulate the minimum distance between the guide bar and the conveyor belt, thereby controlling the stacking height of aluminum products. It can be adjusted according to specific usage conditions, making it highly practical.

[0014] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0019] like Figure 1-5 As shown, a drying device for aluminum product processing includes a tunnel furnace dryer body 2 with a conveyor belt 1, and further includes a smoothing unit mounted on the feed end of the tunnel furnace dryer body 2. The smoothing unit includes a rotating shaft 3 mounted on the feed end of the tunnel furnace dryer body 2 via a pair of bearing seats and located above the conveyor belt 1; a pair of adjusting discs 7 symmetrically mounted on both ends of the rotating shaft 3; several smoothing rods 4 distributed along the circumference of the rotating shaft 3 and whose ends are adjustable and mounted on the adjusting discs 7, which are parallel to the rotating shaft 3; and a drive mechanism for driving the rotating shaft 3 to rotate. The length direction of the smoothing rods 4 is perpendicular to the conveying direction of the conveyor belt 1.

[0020] In the above technical solution, the rotation tangent direction at the bottom of the rotating shaft 3 is opposite to the conveying direction of the conveyor belt 1. When in use, several aluminum products are placed on the conveyor belt 1. The conveyor belt 1 will carry the aluminum products through the smoothing unit. The drive mechanism drives the rotating shaft 3 to rotate. Through a pair of adjusting discs 7, several smoothing rods 4 will rotate. The smoothing rods 4 will intercept the aluminum products located on the upper layer. At this time, the conveyor belt 1 will still carry the aluminum products on the lower layer to continue moving. This can control the stacking height of the aluminum products and prevent several aluminum products from piling up together, which would cause the internal aluminum products to not be dried. The safety of use is high. At the same time, the rotating shaft 3 can drive the guide rod 4 to rotate. If the guide rod 4 is fixed at a certain height, the aluminum products are prone to jamming. By driving several guide rods 4 to rotate through the rotating shaft 3, the stacking height of the aluminum products can be controlled, the jamming problem can be avoided, and damaging friction between the aluminum products can be avoided. The position of the guide bar 4 on the adjustment plate 7 mechanism can be adjusted to adjust the minimum distance between the guide bar 4 and the conveyor belt 1, control the stacking height of aluminum products, and can be adjusted according to specific usage conditions, making it highly practical. This drying device can not only dry aluminum products, but also other common metal parts; the main body 2 of the tunnel furnace dryer is a mature existing technology, so only part of the structure is shown in the figure, and its working principle and structure will not be described in detail in this article.

[0021] In a preferred embodiment of the present invention, the adjusting disk 7 mechanism includes a mounting disk 5 coaxially fixedly sleeved on the end of the rotating shaft 3, a mounting sleeve 6 coaxially sleeved on the outside of the rotating shaft 3 and fixedly connected to the mounting disk 5, an adjusting disk 7 coaxially rotatably mounted on the mounting sleeve 6, and several sets of sliding mechanisms arranged at intervals along the circumferential direction of the mounting disk 5 and slidably mounted on the mounting disk 5 along the radial direction corresponding to the mounting disk 5. The mounting sleeve 6 has a protruding flange, and a hexagonal pressure plate 8 is threaded onto the end of the mounting sleeve 6. The two ends of the handle 4 are respectively mounted on corresponding sliding mechanisms. Each sliding mechanism is equipped with a first pulley 9. The adjusting disc 7 has several arc-shaped grooves 10 arranged along the circumferential direction off-axis. The first pulley 9 is slidably inserted into the corresponding arc-shaped groove 10.

[0022] In the above technical solution, loosening the hexagonal pressure plate 8 allows the adjustment plate 7 to rotate relative to the mounting plate 5. Through the cooperation of the arc groove 10 and the first pulley 9, several sets of sliding mechanisms can be brought together or dispersed simultaneously, and several levers 4 can be adjusted at the same time. The operation is simple and convenient. After the adjustment is completed, tighten the hexagonal pressure plate 8. The adjustment plate 7 is tightly clamped by the cooperation of the hexagonal pressure plate 8 and the flange.

[0023] In a preferred embodiment of the present invention, the sliding mechanism includes a mounting base 11 slidably connected to the mounting plate 5, a second pulley 12 slidably connected to the mounting base 11 along the sliding direction of the mounting base 11 and connected to the end of the handle 4, a transmission plate 13 slidably connected to the mounting base 11 along the sliding direction of the mounting base 11 and capable of contacting the side of the second pulley 12 near the axis of the mounting plate 5, and a spring 14 mounted on the mounting base 11 and abutting against the side of the transmission plate 13 away from the second pulley 12, wherein the first pulley 9 is mounted on the mounting base 11.

[0024] In the above technical solution, when the guide bar 4 comes into contact with the aluminum products, if several aluminum products become stuck together and cannot be separated, the guide bar 4 will not forcibly push the aluminum products, as forcibly pushing the aluminum products would damage them. In this case, the guide bar 4 will transmit the resistance to the second pulley 12, and the second pulley 12 will be forced to slide upward on the mounting base 11 to avoid the corresponding aluminum products. However, the upward sliding of the second pulley 12 on the mounting base 11 after encountering resistance will also be controlled accordingly. When the second pulley 12 slides upward on the mounting base 11, it will further compress the spring 14, which will increase the resistance of the second pulley 12 sliding upward. The greater the upward movement distance, the greater the resistance it encounters when sliding.

[0025] In a preferred embodiment of the present invention, the drive mechanism includes a motor 15 mounted on the feed end of the tunnel oven dryer body 2 via a mounting bracket, a pair of synchronous pulleys respectively fixedly sleeved on the end of the rotating shaft 3 and the output shaft of the motor 15, and a synchronous belt 16 that is connected to the pair of synchronous pulleys for transmission.

[0026] In the above technical solution, the motor 15 drives one of the synchronous pulleys to rotate, and the synchronous pulley connected to the rotating shaft 3 is driven to rotate through the synchronous belt 16.

[0027] In a preferred embodiment of this utility model, the dial on the adjustment plate 7 has a handle 17.

[0028] In the above technical solution, the handle 17 facilitates the rotation of the adjustment disc 7 during adjustment.

[0029] In a preferred embodiment of the present invention, a guide rod 18 that slides through the mounting base 11 is fixedly mounted on the side of the transfer plate 13 away from the second pulley 12. The length direction of the guide rod 18 is consistent with the sliding direction of the second pulley 12, and the spring 14 is sleeved on the guide rod 18.

[0030] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0031] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0032] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
