Description

Technical Field

[0001] The invention relates to the technical field of metal processing part manufacturing, and in particular to a metal processing part drying system. Background Art

[0002] In the production process of metal parts, it is generally necessary to dry the metal parts. Drying of metal parts is one of the important steps that affect the quality of metal parts. The degree of drying of metal parts directly reflects how long their shelf life is. When drying metal accessories, the painted metal accessories are usually placed in a dryer. A heating component is provided inside the dryer, which maintains the temperature in the dryer at 50 to 60 degrees.

[0003] For example, the application document with Chinese invention publication number CN118045732B discloses an integrated device for painting and drying metal parts. The device is achieved by arranging jet pipes opposite to each other in a drying hood. The gas ejected from the jet pipes directly intersects above the metal parts, thereby changing the direction of the gas and dividing the drying hood into a first space and a second space to dry the surface of the metal parts.

[0006] Preferably, the surface of the conveyor belt device is hollowed out.

[0007] Preferably, a reciprocating assembly is provided below the fixed plate, a connecting block is installed at the working end of the reciprocating assembly, and a plurality of groups of rubber strips are glued to the lower end surface of the connecting block.

[0008] Preferably, the reciprocating assembly comprises two sets of slide rails fixedly mounted between two sets of baffles and arranged in parallel, an electric slider is slidably mounted on each set of slide rails, and the connecting block is fixedly mounted between the two sets of electric sliders.

[0009] Preferably, the lifting assembly comprises an electric push rod fixedly mounted on a fixed plate, wherein an output end of the electric push rod faces downward and is fixedly connected to the movable block.

[0010] Preferably, the drying mechanism comprises a plurality of sets of fans fixedly installed in a linear array, and the output ends of the fans face downward and are fixedly provided with air outlet hoods.

[0011] Preferably, two groups of symmetrically arranged wind shields are fixedly installed on both sides of the inner wall of the air outlet cover, and the two groups of wind shields are distributed in an eight-shaped shape.

[0012] Preferably, symmetrically arranged air outlets are fixedly mounted on both sides of the lower end of the air outlet cover, the air inlet ends of the air outlets are located above the corresponding wind shield plates, and the air outlet ends of the air outlets are located below the corresponding wind shield plates.

[0013] Preferably, the driving assembly includes a cover shell fixedly mounted on the upper end surface of the mounting plate, a motor is fixedly mounted on an outer wall of one side of the cover shell, the output end of the motor is fixedly connected to a rotating shaft after rotating through the side wall of the cover shell, a bevel gear is keyed on the rotating shaft, a vertically arranged rotating rod is rotatably mounted inside the cover shell, a bevel gear is fixedly sleeved on the outer side of the rotating rod, the bevel gear is meshingly connected with the bevel gear, and the upper end of the rotating rod is fixedly connected to the connecting plate after rotating through the top wall of the cover shell.

[0014] Preferably, the magnetic poles of the two groups of magnetic blocks are opposite.

[0015] Compared with the prior art, the advantages of the present invention are: In the present application, an electric slider, a connecting block, a rubber strip, etc. are arranged. When the steel pipe moves to the lower end of the slide rail, the electric slider is started, so that the electric slider slides back and forth along the inner wall of the slide rail and drives the connecting block to move synchronously. The movement of the connecting block drives several rubber strips to move synchronously, so that the rubber strip can reciprocate and wave the steel pipe, thereby making the steel pipe flat on the conveyor belt device, avoiding multiple steel pipes from being stacked together and causing insufficient subsequent drying, thereby improving the subsequent drying effect.

[0016] In the present application, by configuring an electric push rod, a movable block, an air bag and a liquid level tank, when the electric push rod drives the air bag to fit the surface of the conveyor belt device, the liquid inside the air bag can enter the liquid level tank opened inside the movable block, and the liquid level sensor will send an electrical signal to the controller, which will control the air volume of the subsequent fan after receiving the signal, thereby controlling the air volume of the fan according to the number of steel pipes. On the one hand, it can avoid the situation where the steel pipes are not completely dried due to the small air volume, and on the other hand, it can avoid the situation where the temperature of the steel pipes is too high and oxidation occurs due to the large air volume drying a small number of steel pipes, thereby further improving the uniformity of drying and reducing the damage to the steel pipes caused by drying.

[0017] In the present application, by arranging the fan, air outlet hood, wind shield and air outlet, on the one hand, the hot air blown out from the middle position of the air outlet hood can directly act on the surface of the steel pipe to dry it, and on the other hand, the hot air blocked by the wind shield will enter the two groups of air outlets respectively. When passing through a narrow passage, the wind speed is accelerated and the temperature is reduced, so that the steel pipe can be fully dried from both sides. At the same time, the cooled hot air is used to dry the inside of the steel pipe, which can reduce the oxidation inside the steel pipe and improve the quality of drying the steel pipe.

[0018] In the present application, by configuring the cover, the connecting plate and the magnetic blocks, when the motor is running, the meshing action between the bevel gear and the bevel gear can drive the rotating rod to rotate. When the rotating rod rotates, it drives the connecting plate and the two groups of magnetic blocks thereon to move synchronously. Since the magnetic poles of the two groups of magnetic blocks are opposite, when the two groups of magnetic blocks rotate, they will exert force on several steel pipes on the conveyor belt device, thereby causing the steel pipes to roll during the drying process, so that the residual liquid inside the steel pipes can evaporate faster, thereby improving the efficiency of steel pipe drying.

[0019] In summary, the present application, through the setting of the above-mentioned structure, can control the air volume according to the number of parts while avoiding the stacking of steel pipes, fully dry the surface of the steel pipe from multiple angles and in all directions, and reduce the oxidation inside the steel pipe.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1 to 10A metal processing parts drying system comprises a base 1, wherein two groups of baffles 11 arranged symmetrically are fixedly mounted on the upper end surface of the base 1, and a conveyor belt device 14 is installed between the two groups of baffles 11, and the conveyor belt device 14 is a prior art, and its specific structural design is not repeated here. A fixed shell 12 is fixedly connected between the top ends of the two groups of baffles 11, and a fixed plate 121 is fixedly mounted at the front of the fixed shell 12 (i.e., the metal processing parts entry end), and an electric push rod 3 is fixedly mounted on the upper end of the fixed plate 121, and the output end of the electric push rod 3 faces downward and is fixedly connected with a movable block 31, and an air bag 32 is glued to the lower end of the movable block 31, and the air bag 32 is filled with flowing liquid, which can be water, alcohol, lubricating oil, etc. A liquid level tank 34 connected to the air bag 32 is opened inside the movable block 31, and a liquid level sensor 33 is arranged inside the liquid level tank 34, and the liquid level sensor 33 is a prior art, and its specific structural design is not repeated here.

[0024] When the liquid in the airbag 32 enters the liquid level tank 34 , the liquid level sensor 33 sends an electrical signal to the controller 13 , and the controller 13 controls the air output of the subsequent fan 4 after receiving the signal.

[0025] Two groups of slide rails 2 are fixedly installed in parallel between the two groups of baffles 11 in front of the movable block 31, and an electric slider 21 is slidably installed on each group of slide rails 2. A connecting block 22 is fixedly installed between the two groups of electric sliders 21. The lower end surface of the connecting block 22 is glued with multiple groups of vertically arranged rubber strips 23. The two groups of electric sliders 21 move synchronously, thereby driving the connecting block 22 to move. The movement of the connecting block 22 can also drive the multiple groups of rubber strips 23 to move synchronously, so that when several steel pipes reach the lower end of the rubber strip 23, the reciprocating motion of the rubber strip 23 driven by the connecting block 22 can make the rubber strip 23 reciprocate and undulate the steel pipe, so that the steel pipe can be laid flat on the conveyor belt device 14, so as to avoid multiple steel pipes being stacked together to cause insufficient subsequent drying, thereby improving the subsequent drying effect.

[0026] A plurality of sets of fans 4 are fixedly installed in a linear array on the rear side of the interior of the fixed shell 12. The output end of the fans 4 faces downward and is fixedly installed with an air outlet hood 41. The number of fans 4 and the air outlet hood 41 can be set according to actual needs. The more fans 4 there are, the faster the drying effect and speed will be. Two sets of wind shields 42 are fixedly installed on both sides of the inner wall of the air outlet hood 41 in a symmetrical arrangement. The two sets of wind shields 42 are arranged in an eight-shaped pattern. Two sets of air outlets 43 are fixedly installed on both sides of the lower end of the air outlet hood 41 in a symmetrical arrangement. The air inlet end of the air outlet 43 is located above the corresponding wind shield 42, and the air outlet end of the air outlet 43 is located below the corresponding wind shield 42.

[0027] When the fan 4 is running, part of the hot air blown out enters from the upper end of the air outlet 43 under the guidance of the wind shield 42 and is blown out from the lower end of the air outlet 43. On the one hand, the flow velocity of the hot air will be accelerated when passing through the narrow passage inside the air outlet 43, and on the other hand, its temperature will be reduced while passing through the narrow passage inside the air outlet 43. Then the hot air is discharged through the lower end of the air outlet 43. At this time, the cooled hot air will be directly blown onto the steel pipe (metal processing part) to dry it.

[0028] A plurality of mounting plates 5 fixedly mounted between two baffles 11 are arranged in a linear array on the inner side of the conveyor belt device 14, and each mounting plate 5 is located directly below the corresponding fan 4. Two groups of symmetrically arranged cover shells 51 are fixedly mounted on the upper end surface of the mounting plate 5, and a motor 52 is fixedly mounted on the outer wall of one side of the cover shell 51. The output end of the motor 52 is fixedly connected to a rotating shaft 53 after rotating through the side wall of the cover shell 51, and a bevel gear 54 is keyed on the rotating shaft 53. A vertically arranged rotating rod 56 is rotatably mounted inside the cover shell 51, and a bevel gear 55 is fixedly sleeved on the outer side of the rotating rod 56, and the bevel gear 55 is meshed with the bevel gear 54. The upper end of the rotating rod 56 is fixedly connected to a connecting plate 57 after rotating through the top wall of the cover shell 51, and two groups of symmetrically arranged magnetic blocks 58 are fixedly mounted on the upper end surface of the connecting plate 57, and the magnetic poles of the two groups of magnetic blocks 58 are opposite.

[0029] When the motor 52 is running, the meshing action between the bevel gear 54 and the bevel gear 55 can drive the rotating rod 56 to rotate. When the rotating rod 56 rotates, it drives the connecting plate 57 and the two groups of magnetic blocks 58 thereon to move synchronously. Since the magnetic poles of the two groups of magnetic blocks 58 are opposite, when the two groups of magnetic blocks 58 rotate, a force is generated on several steel pipes on the conveyor belt device 14, so that the steel pipes roll during the drying process, so that the residual liquid inside the steel pipes can evaporate faster, thereby improving the efficiency of steel pipe drying.

[0030] The specific working principle of the present invention is as follows: the steel pipe is intermittently placed on the surface of the conveyor belt device 14, and the conveyor belt device 14 is driven to rotate. The conveyor belt device 14 will drive the steel pipe to enter the fixed shell 12. When the steel pipe moves to the lower end of the slide rail 2, the electric slider 21 is started, so that the electric slider 21 slides back and forth along the inner wall of the slide rail 2 and drives the connecting block 22 to move synchronously. The movement of the connecting block 22 will drive a number of rubber strips 23 to move synchronously. When a number of steel pipes reach the lower end of the rubber strip 23, the reciprocating motion of the rubber strip 23 is driven by the connecting block 22, so that the rubber strip 23 can reciprocate and wave the steel pipe, thereby making the steel pipe flat on the conveyor belt device 14, avoiding multiple steel pipes from being stacked together to cause insufficient subsequent drying, thereby improving the subsequent drying effect.

[0031] After the rubber strip 23 has leveled the steel pipes, the conveyor belt device 14 will drive the steel pipes to continue moving until the steel pipes reach the lower end of the movable block 31. At this time, the electric push rod 3 is started, so that the electric push rod 3 pushes the movable block 31 to move downward. The downward movement of the movable block 31 will drive the airbag 32 to move synchronously until the surface of the airbag 32 fits with the surface of the conveyor belt device 14. Since flowing liquid is arranged inside the airbag 32 and since there are several steel pipes on the surface of the conveyor belt device 14, when the surface of the airbag 32 fits with the surface of the conveyor belt device 14, the several steel pipes will exert force on the liquid in the airbag 32. At this time, the internal pressure of the airbag 32 increases, and the liquid in the airbag 32 enters the liquid level groove 34 opened inside the movable block 31. A liquid level sensor 33 is provided in the part. When the liquid inside the airbag 32 enters the liquid level tank 34, the liquid level sensor 33 will send an electrical signal to the controller 13. The controller 13 will control the air output of the subsequent fan 4 after receiving the signal. Since the number of steel pipes transported intermittently on the conveyor belt device 14 is different in each batch, when the number of steel pipes on the conveyor belt device 14 is large, the liquid level entering the liquid level tank 34 will be higher. Therefore, when the liquid level is high, the controller 13 will increase the air output of the fan 4 to avoid the situation where the steel pipe is not completely dried due to the small air output. When the liquid level is low, the controller 13 will reduce the air output of the fan 4 to avoid the situation where a large air volume is used to dry a small number of steel pipes, causing the steel pipe temperature to be too high and oxidation to occur, thereby further improving the uniformity of drying and reducing the damage to the steel pipe due to drying.

[0032] When the steel pipe reaches the lower end of the fan 4, the controller 13 will start the fan 4, and the fan 4 will blow the hot air into the air outlet hood 41. Since two sets of symmetrical wind shields 42 are fixedly installed inside the air outlet hood 41, when the fan 4 blows the hot air out, the hot air is divided into three parts under the action of the wind shields 42. The hot air entering the air outlet hood 41 will directly contact the outer surface of the steel pipe, and then take away the liquid remaining on the outer surface of the steel pipe. When the fan 4 is blowing, the motor 52 is started synchronously, so that the motor 52 drives the rotating shaft 53 to rotate. The rotation of the rotating shaft 53 will drive the bevel gear 54 to move synchronously. The rotation of the bevel gear 54 will mesh with the bevel gear 55, so that the bevel gear 55 drives the rotating rod 56 to rotate along the inner wall of the cover shell 51. The rotation of the rotating rod 56 will drive the connecting plate 57 to move synchronously. The movement of the connecting plate 57 will drive the two groups of magnetic blocks 58 to move synchronously. Since the magnetic poles of the two groups of magnetic blocks 58 are opposite, when the two groups of magnetic blocks 58 rotate, they will generate force on several steel pipes on the conveyor belt device 14, so that the steel pipes will roll during the drying process, so that the residual liquid inside the steel pipes can evaporate faster, thereby improving the efficiency of steel pipe drying.

[0033] The hot air blocked by the wind shield 42 will enter the two groups of air outlets 43 respectively. When the hot air enters the air outlet 43, it will pass through the narrow channel inside the air outlet 43. At this time, the flow rate of the hot air is accelerated, so that the temperature of the air outlet 43 is reduced when passing through the narrow channel, and then the hot air is discharged through the lower end of the air outlet 43. At this time, the cooled hot air will be directly blown to the steel pipe. At this time, due to the rolling of several steel pipes, the hot air blown out of the air outlet 43 can directly dry the liquid remaining in the internal threads of the steel pipe, so that when drying the steel pipe, not only the surface of the steel pipe can be dried, but also the liquid remaining in the internal threads of the steel pipe can be dried, thereby improving the drying effect. At the same time, using the cooled hot air to dry the inside of the steel pipe can reduce the oxidation inside the steel pipe (the smoother the steel pipe, the less likely it is to oxidize at the same temperature, and the higher the temperature, the easier it is to oxidize), thereby improving the quality of steel pipe drying.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
