Description

Technical Field

[0001] This invention relates to the field of computer casing processing technology, and in particular to a dyeing apparatus for computer casings. Background Technology

[0002] Computers, commonly known as PCs, are modern intelligent electronic devices capable of running programs and automatically and rapidly processing massive amounts of data. With the rapid development of electronic technology, people have increasingly higher demands for the richness of colors on the surface of computer casings. During the processing of the casing, the color on the surface is achieved through processes such as cleaning, chemical polishing, dyeing, sealing, and baking. Then, the casings are manually mounted piece by piece on a rack, which is then manually lifted and placed into a cleaning tank. After cleaning, they are manually lifted out and placed into a chemical polishing tank. After a specific time, they are lifted out and placed into a dyeing tank. After dyeing for several hours, they are placed into a sealing tank to prevent color fading. Finally, they are placed in an oven to remove surface water droplets.

[0003] In the prior art, such as Chinese Patent No. CN208538030U, a laptop casing is disclosed, including a lower casing. The lower surface of the inner sidewall of the lower casing is fixedly connected to the lower surfaces of four support plates. A first sliding sleeve is engaged with the left side of the support plate, and a first sliding rod is sleeved on the inner wall of the first sliding sleeve. The right end of the first sliding rod is fixedly connected to the left side of a first connecting plate, and the right side of the first connecting plate is fixedly connected to the left end of a first support rod. By setting up a first sliding rod, a spring, a first sliding sleeve, a trapezoidal block, a second sliding rod, a second support rod, a locking block, and a second groove, the operator can move the trapezoidal block by pushing and pulling a ring, causing the roller to move back and forth in the two first grooves on the side of the trapezoidal block. This allows the first sliding rod to drive the locking block into or out of the second groove, realizing the installation, fixing, and disassembly of the main unit casing, saving time and effort and bringing convenience to the operator's work.

[0004] However, in the existing technology, computer casings are processed by manually handling the hangers and then putting the casings on the hangers into the dyeing tank for dyeing. However, during the dyeing process, the soaking time of each tank cannot be effectively controlled, the time is not accurate, and the work time is even forgotten, which affects the dyeing effect of the casings and thus affects the product quality. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the existing technology that, during the processing of computer casings, the hanging fixtures are manually moved and the casings on the fixtures are then placed into the dyeing tank for dyeing. However, during the dyeing process, the soaking time in each tank cannot be effectively controlled, the time is inaccurate, or the work time is even forgotten, which affects the dyeing effect of the casings and thus affects the product quality. Therefore, this invention proposes a dyeing device for computer casings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dyeing device for computer casings, comprising: a dyeing pool, a buzzer provided on one outer surface of the dyeing pool, a timer provided on the front surface of the dyeing pool near one side, and a flashing light provided on the front surface of the dyeing pool near the top.

[0007] A movable component is fixedly installed on the top of the dyeing tank. The movable component includes a forward and reverse motor. A threaded rod is fixedly installed at the output end of the forward and reverse motor. A support frame is threadedly fitted on the outer surface of the threaded rod. A limiting rod is movably embedded on the front surface of the support frame near the bottom. A hydraulic rod is fixedly installed at the top inside the support frame. A fixing plate is fixedly installed at the bottom of the hydraulic rod. Multiple connecting rods are fixedly installed at the bottom of the fixing plate. The outer surfaces of the multiple connecting rods are all connected to spring clips by bolts.

[0008] Preferably, multiple telescopic rods are fixedly installed on the top of both sides of the fixed plate, and the top of each of the two telescopic rods is fixedly connected to the top of the inside of the support frame. This facilitates the support of the fixed plate by the two telescopic rods, increases stability, and prevents shaking during movement.

[0009] Preferably, the bottom of the forward and reverse motors is fixedly connected to the top of the dyeing tank near the front surface, and both ends of the limiting rod are fixedly installed on the top of the dyeing tank near one side, which facilitates the strengthening of the stability of the forward and reverse motor installation and allows the support frame to move normally under the limitation of the limiting rod.

[0010] Preferably, a fixing block is fixedly installed on the top of the dyeing pool near the other side, and one end of the threaded rod is movably embedded in the front surface of the fixing block, so that the threaded rod can be supported by the fixing block, preventing the threaded rod from becoming unstable and shaking during rotation, and improving stability.

[0011] Preferably, an L-shaped rod is fixedly installed at the top of the dyeing pool near the rear surface, with one end of the L-shaped rod extending movably through to the front surface of the support frame. This facilitates improved stability of the support frame during movement, thanks to the auxiliary support of the L-shaped rod.

[0012] Preferably, springs are provided on the outer surfaces of both multi-section telescopic rods. One end of each spring is fixedly connected to the top of the fixed plate, and the other end of each spring is fixedly installed on the top inside the support frame. This facilitates the buffering effect of the hydraulic rods under the action of the springs, which helps to smoothly push the fixed plate.

[0013] Preferably, a square groove is formed on the outer surface of the dyeing pool near the bottom, and a heating chamber is formed on one side inside the square groove. An electric heating plate is provided at the bottom of the heating chamber. Heat is generated by activating the electric heating plate, and the temperature inside the heating chamber gradually increases under the heating of the electric heating plate, thereby facilitating the increase of the temperature of the dyeing pool.

[0014] Preferably, the top of the heating chamber is provided with multiple heat-conducting plates, the inside of the square groove is fitted with an inspection door by multiple screws, and the rear surface of the dyeing pool is fixedly fitted with an installation plate. This facilitates the heat transfer to be accelerated under the action of multiple heat-conducting plates, thereby increasing the temperature of the dyeing solution inside the dyeing pool and accelerating the dyeing process of the computer casing. The inspection door also allows maintenance personnel to easily inspect the inside of the heating chamber.

[0015] Preferably, a water pump is fixedly installed on the top of the mounting plate. The water inlet of the water pump is connected to a suction pipe via a flange. A tapered tube is fixedly connected to one end of the suction pipe. A filter screen is fixedly installed on the inner wall of the suction pipe near one end. This facilitates the pumping of the dyeing solution from the dyeing pool into the suction pipe through the tapered tube under the pressure of the water pump. The tapered tube is wider at the bottom and narrower at the top, which helps to expand the absorption range and concentrate the flow into the suction pipe. The filter screen can filter out impurities in the dyeing solution, preventing impurities from entering the water pump.

[0016] Preferably, the outlet end of the water pump is connected to a drain pipe via a flange. A circular hole is provided on the rear surface wall inside the dyeing tank. The outer surface of the suction pipe is fixedly connected to the inner wall of the circular hole. One end of the suction pipe extends into the interior of the dyeing tank, facilitating the discharge of dyeing solution into the drain pipe. The drain pipe is connected to an external waste liquid tank, and the dyeing solution is discharged into the external waste liquid tank through the drain pipe, facilitating subsequent centralized treatment and discharge of waste liquid.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0018] 1. In this invention, when in use, the computer casing is hung on the spring clip holder, with the upper and lower ends of the spring clip holder engaging inside the computer casing to support it. Then, the hydraulic rod is activated to slowly push the fixing plate downwards, allowing the lower half of the casing to gradually enter the dyeing pool for dyeing. The dyeing time is set using a timer. Next, the external power supply to the forward and reverse motors is turned on, causing the threaded rod to rotate via the motor's output. This causes the support frame to slowly move backwards, thus moving the casing, fixed by the spring clip holder, backwards a certain distance. Then, the reverse rotation of the forward and reverse motors causes the threaded rod to rotate in the opposite direction, thereby moving the support frame and the lower... The shell moves forward and, driven by the forward and reverse motors, maintains a constant reciprocating motion inside the dyeing tank. Since the lower surface of the shell is continuously dyed while the middle section is dyed intermittently, the overall color effect on the shell is lighter towards the center and darker towards the sides. When the timer reaches its preset time, the controller buzzer sounds to remind the staff that dyeing is complete, and the shell can be removed. Simultaneously, the controller controls a flashing light to indicate which dyeing tank has finished dyeing, allowing staff to locate the shell promptly. This achieves precise control of the shell's soaking time, improving the dyeing effect.

[0019] 2. In this invention, when the forward and reverse motors drive the support frame to reciprocate, the top of the support frame slides on the outer surface of the L-shaped rod. With the auxiliary support of the L-shaped rod, the stability of the support frame during movement is improved. Under the action of the two multi-section telescopic rods and the spring, the fixed plate is supported, increasing stability and preventing shaking during movement. Under the action of the spring, the hydraulic rod is buffered, which is conducive to smoothly pushing the fixed plate.

[0020] 3. In this invention, during use, the operator can activate the heating plate according to the dyeing situation to generate heat. Under the heating of the heating plate, the temperature inside the heating chamber gradually increases. The heating chamber is equipped with multiple heat-conducting plates, which transfer heat to the top of the heating chamber, gradually increasing the temperature at the bottom of the dyeing pool. Through heat transfer, the temperature of the dyeing solution inside the dyeing pool is increased, providing more energy for the movement of dye molecules, promoting dye dissolution and dispersion, increasing dye penetration speed, and improving work efficiency. An inspection door is installed inside the square tank with screws. The operator can remove the inspection door by unscrewing the screws, facilitating maintenance personnel to inspect the inside of the heating chamber. When the dye solution needs to be replaced after multiple dyeing cycles, the water pump is started. Under the pressure of the water pump, the dye solution inside the dyeing tank is drawn into the suction pipe through the conical tube, and then discharged into the drain pipe. The drain pipe is connected to the external waste liquid tank. The dye solution is discharged into the external waste liquid tank through the drain pipe, which facilitates the centralized treatment and discharge of waste liquid. The structure of the conical tube is shown in the figure. It is set with a wider bottom and a narrower top, which helps to expand the absorption range and concentrate the flow into the suction pipe. When the dye solution flows into the suction pipe, it will pass through the filter screen. The filter screen can filter out impurities in the dye solution, preventing impurities from entering the water pump and causing damage to the water pump, thus affecting the normal operation of the water pump and achieving the effect of facilitating the discharge of waste liquid.

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Please see Figure 1-7 This invention provides a technical solution: a dyeing device for computer casings, comprising: a dyeing pool 1, a buzzer 2 provided on one outer surface of the dyeing pool 1, a timer 3 provided on the front surface of the dyeing pool 1 near one side, and a flashing light 4 provided on the front surface of the dyeing pool 1 near the top; a moving component 5, the moving component 5 being fixedly installed on the top of the dyeing pool 1, the moving component 5 including a forward and reverse motor 501, a threaded rod 502 fixedly installed at the output end of the forward and reverse motor 501, a support frame 503 threadedly sleeved on the outer surface of the threaded rod 502, a limiting rod 507 movably embedded on the front surface of the support frame 503 near the bottom, a hydraulic rod 504 fixedly installed at the top inside the support frame 503, a fixing plate 505 fixedly installed at the bottom of the hydraulic rod 504, and multiple connecting rods 506 fixedly installed at the bottom of the fixing plate 505, the outer surfaces of the multiple connecting rods 506 being connected to spring clips 508 by bolts.

[0032] like Figures 1-4 As shown, multiple telescopic rods 6 are fixedly installed on the top of the fixed plate 505 near both sides. The top of the two telescopic rods 6 are fixedly connected to the top of the inside of the support frame 503, so that the fixed plate 505 can be supported by the two telescopic rods 6, increasing stability and preventing shaking during movement.

[0033] like Figures 1-4As shown, the bottom of the forward and reverse motor 501 is fixedly connected to the top of the dyeing pool 1 near the front surface. Both ends of the limiting rod 507 are fixedly installed on the top of the dyeing pool 1 near one side, which helps to strengthen the stability of the forward and reverse motor 501 installation. Under the limitation of the limiting rod 507, the support frame 503 can move normally.

[0034] like Figure 2 and Figure 3 As shown, a fixing block 9 is fixedly installed on the top of the dyeing pool 1 near the other side. One end of the threaded rod 502 is movably embedded in the front surface of the fixing block 9, so that the threaded rod 502 can be supported by the fixing block 9, preventing the threaded rod 502 from becoming unstable and shaking during rotation, and improving stability.

[0035] like Figures 1-3 As shown, an L-shaped rod 8 is fixedly installed on the top of the dyeing pool 1 near the rear surface. One end of the L-shaped rod 8 extends through to the front surface of the support frame 503, which facilitates the improvement of the stability of the support frame 503 when it moves with the auxiliary support of the L-shaped rod 8.

[0036] like Figures 1-3 As shown, springs 7 are provided on the outer surfaces of the two multi-section telescopic rods 6. One end of each spring 7 is fixedly connected to the top of the fixed plate 505, and the other end of each spring 7 is fixedly installed on the top inside the support frame 503. This facilitates the buffering effect of the hydraulic rod 504 under the action of the springs 7, which helps to smoothly push the fixed plate 505.

[0037] like Figures 6-7 As shown in the figure, a square groove 17 is provided on the outer surface of the dyeing pool 1 near the bottom. A heating chamber 18 is provided on one side inside the square groove 17. An electric heating plate 19 is provided at the bottom inside the heating chamber 18. Heat is generated by activating the electric heating plate 19. Under the heating of the electric heating plate 19, the temperature inside the heating chamber 18 gradually increases, thereby facilitating the increase of the temperature of the dyeing pool 1.

[0038] like Figures 1-2 and Figures 6-7 As shown, the top of the heating chamber 18 is provided with multiple heat-conducting plates 21, and the inside of the square groove 17 is equipped with an inspection door 10 by multiple screws. The rear surface of the dyeing pool 1 is fixedly installed with an installation plate 11, which facilitates the heat transfer to be accelerated under the action of multiple heat-conducting plates 21, thereby increasing the temperature of the dyeing solution inside the dyeing pool 1 and helping to speed up the dyeing process of the computer casing. The inspection door 10 facilitates maintenance personnel to inspect the inside of the heating chamber 18.

[0039] like Figure 2 and Figure 5As shown, a water pump 12 is fixedly installed on the top of the mounting plate 11. The water inlet of the water pump 12 is connected to a liquid extraction pipe 13 via a flange. A conical pipe 15 is fixedly connected to one end of the liquid extraction pipe 13. A filter screen 16 is fixedly installed on the inner wall of the liquid extraction pipe 13 near one end. This facilitates the extraction of the dyeing solution inside the dyeing pool 1 into the liquid extraction pipe 13 through the conical pipe 15 under the pressure of the water pump 12. The conical pipe 15 has a structure that is wider at the bottom and narrower at the top, which helps to expand the absorption range and concentrate the flow into the liquid extraction pipe 13. Under the filtering action of the filter screen 16, impurities in the dyeing solution can be filtered out, preventing impurities from entering the water pump 12.

[0040] like Figure 2 , Figure 5 and Figure 6 As shown, the outlet end of the water pump 12 is connected to the drain pipe 14 via a flange. A circular hole 20 is provided on the rear surface wall inside the dyeing tank 1. The outer surface of the suction pipe 13 is fixedly connected to the inner wall of the circular hole 20. One end of the suction pipe 13 extends into the interior of the dyeing tank 1, so that the dyeing liquid can be discharged into the drain pipe 14 through the suction pipe 13. The drain pipe 14 is connected to the external waste liquid pool. The dyeing liquid is discharged into the external waste liquid pool through the drain pipe 14, which facilitates the subsequent centralized treatment and discharge of waste liquid.

[0041] The usage and working principle of this device are as follows: When in use, pour the dyeing solution into the dyeing pool 1. Then, hang the computer casing on the spring clip 508. The upper and lower ends of the spring clip 508 are engaged inside the computer casing, supporting it. Then, activate the hydraulic rod 504 to slowly push the fixing plate 505 downwards, allowing the lower half of the casing to gradually enter the dyeing pool 1 for dyeing. At this time, set the dyeing time using the timer 3. Next, turn on the external power supply of the forward and reverse motor 501. The output end of the forward and reverse motor 501 drives the threaded rod 502 to rotate, which in turn drives the support frame 503 to slowly move backwards, thereby moving the casing fixed by the spring clip 508 backwards a certain distance. Then, the forward and reverse motor 501 rotates in the opposite direction... The screw rod 502 rotates in the opposite direction, which in turn moves the support frame 503 and the shell below forward. Driven by the forward and reverse motors 501, the shell maintains a uniform reciprocating motion inside the dyeing tank 1. Since the lower part of the shell surface is continuously dyed, while the middle part is dyed intermittently, the overall color effect on the shell is lighter towards the center and darker towards the sides. When the timer 3 is set, the buzzer 2 of the controller sounds to remind the staff that the dyeing of the shell is over and that the dyeing can be stopped and the shell can be removed. At the same time, the controller controls the flashing light 4 to flash, indicating to the staff which dyeing tank 1 has finished dyeing the shell, making it easier for the staff to find it in time. This achieves the effect of controlling the soaking time of the shell, ensuring precise timing, and improving the dyeing effect. This invention solves the problem of manually handling the hangers during computer casing processing and then immersing the casings in dyeing tanks. However, the immersion time in each tank is difficult to control effectively, resulting in inaccurate timing and even forgetting the start time, affecting the dyeing effect and ultimately impacting product quality. When the forward and reverse motor 501 drives the support frame 503 to reciprocate, the top of the support frame 503 slides on the outer surface of the L-shaped rod 8. With the auxiliary support of the L-shaped rod 8, the stability of the support frame 503 during movement is improved. The two multi-section telescopic rods 6 and the spring 7 provide support for the fixed plate 505, increasing stability and preventing swaying during movement. The spring 7 also supports the hydraulic rod 5. 04 acts as a buffer, facilitating the smooth pushing of the fixed plate 505. The heating plate 19 is electrically connected to an external power source. Workers can activate the heating plate 19 to generate heat, depending on the dyeing situation. Under the heating of the heating plate 19, the temperature inside the heating chamber 18 gradually increases. Multiple heat-conducting plates 21 are installed inside the heating chamber 18, transferring heat to the top of the chamber and gradually raising the temperature at the bottom of the dyeing pool 1. This heat transfer increases the temperature of the dyeing solution inside the dyeing pool 1, providing more energy for the dye molecules to move, promoting dye dissolution and dispersion, increasing dye penetration speed, accelerating the dyeing process of the computer casing, and improving work efficiency. Workers can adjust the settings according to the actual situation.The option to activate the heating plate 19 is selected. An inspection door 10 is installed inside the square tank 17 using screws. Workers can remove the inspection door 10 by unscrewing the screws, facilitating maintenance of the heating chamber 18. When the dyeing solution in the dyeing tank 1 needs to be replaced after multiple dyeing cycles, the water pump 12 is activated. Under the pressure of the water pump 12, the dyeing solution in the dyeing tank 1 is drawn through the conical pipe 15 into the extraction pipe 13, and then discharged into the drain pipe 14. The drain pipe 14 is connected to an external waste liquid tank, facilitating subsequent centralized treatment and discharge of waste liquid. The structure of the conical pipe 15 is as follows... Figure 5 As shown, the bottom is wider and the top is narrower, which helps to expand the absorption range and concentrate the flow into the pumping pipe 13. When the dyeing solution flows into the pumping pipe 13, it will pass through the filter screen 16. Under the filtering action of the filter screen 16, impurities in the dyeing solution can be filtered out, preventing impurities from entering the pump 12 and causing damage to the pump 12, affecting the normal operation of the pump 12, thereby achieving the effect of facilitating the discharge of waste liquid.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
