Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically to a coating device for metal surface treatment with good cooling effect. Background Technology

[0002] Metal surface treatment is a process that artificially forms a surface layer on the base material with different mechanical, physical, and chemical properties from the base material. The purpose of metal surface treatment is to meet the requirements of corrosion resistance, wear resistance, decoration, or other special functions of products. For metal surface treatment, a coating device is often required to coat a protective film or decorative film onto the metal surface.

[0003] For example, patent CN222132404U discloses a device for coating antifouling film on metal surfaces, including a coating module and a cleaning module. The coating module includes a table frame, a pad installed on the top of the table frame, an adhesive box attached to the top of the pad, a motor connected to the adhesive box, and a coating roller movably installed inside the adhesive box. The output shaft of the motor is fixedly connected to the coating roller. The cleaning module includes a top plate installed on the top of the table frame.

[0004] However, the existing equipment has poor coating effect when in use. Not only is the coating angle limited and difficult to adapt to the surface treatment needs of complex workpieces, but it also requires multiple manual operations when adjusting the coating, which increases labor intensity and affects processing efficiency and consistency. Furthermore, the cooling effect is poor and the slow cooling speed directly restricts the overall efficiency of metal surface treatment. Uneven cooling can easily lead to quality defects such as cracking and peeling of the coating, which seriously affects the final quality of metal surface treatment.

[0005] Therefore, in order to solve such problems, we propose a coating device for metal surface treatment with good cooling effect. Utility Model Content

[0006] The purpose of this invention is to provide a coating device for metal surface treatment with good cooling effect, so as to solve the problems mentioned in the background art. When using the existing device, the coating effect is not good. Not only is the coating angle limited and it is difficult to adapt to the surface treatment needs of complex workpieces, but multiple manual operations are required when adjusting the coating, which increases labor intensity and affects the processing efficiency and consistency. Furthermore, the cooling effect is poor and the slow cooling speed directly restricts the overall efficiency of metal surface treatment. Uneven cooling can easily lead to quality defects such as cracking and peeling of the coating, which seriously affects the final quality of metal surface treatment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coating device for metal surface treatment with good cooling effect, comprising a base, a first sliding groove provided at the rear of the top of the base, a first lead screw rotatably connected in the first sliding groove, a first motor fixedly connected to the left end of the first lead screw, a first slider threadedly connected to the first lead screw, a bracket fixedly connected to the top of the first slider, a U-shaped frame fixedly connected to the bracket, a second motor fixedly connected to the top of the U-shaped frame, the output end of the second motor penetrating the top of the U-shaped frame, a rotating component fixedly connected to the output end of the second motor, a sleeve rod movably connected to the side of the rotating component away from the output end of the second motor, a deflecting rod rotatably connected to the U-shaped frame, a fixing block fixedly connected to the left end of the deflecting rod, a nozzle fixedly connected to the bottom of the fixing block, a deflecting component fixedly connected to the deflecting rod, and the deflecting component movably connected to the sleeve rod.

[0008] Furthermore, a limiting groove is provided behind the first sliding groove at the top of the base, and a limiting rod is fixedly connected in the limiting groove. An L-shaped block is fixedly connected to the lower part of the rear outer wall of the bracket, and the L-shaped block is movably connected to the limiting rod.

[0009] Furthermore, a fixing rod is fixedly connected to the lower part of the front outer wall of the bracket, and a scraper is fixedly connected to the fixing rod.

[0010] Furthermore, a fan is fixedly connected to the bottom of the fixing block, and the fan faces the nozzle.

[0011] Furthermore, a liquid storage tank is fixedly connected to the bottom of the base, a pump body is fixedly connected to the rear of the liquid storage tank, a pipe is fixedly connected to the pump body, and the end of the pipe is fixedly connected to the nozzle.

[0012] Furthermore, a second sliding groove is provided on the left side of the front top of the base, a second lead screw is rotatably connected in the second sliding groove, a third motor is fixedly connected to the left end of the second lead screw, a second slider is threadedly connected to the second lead screw, and a left clamping plate is fixedly connected to the top of the second slider. A right clamping plate is fixedly connected to the right side of the top of the base, and a placement frame is fixedly connected to the top of the base.

[0013] Furthermore, the top of the base is provided with a mounting groove, in which a condenser tube is embedded, and both the mounting groove and the condenser tube are S-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are: a coating device for metal surface treatment with good cooling effect, which adopts a novel structural design, the specific details of which are as follows: (1) This coating device for metal surface treatment with good cooling effect can drive the nozzle to achieve flexible multi-angle deflection through the coordinated transmission of the second motor, rotating part, sleeve rod, deflecting part and deflecting rod. When the output end of the second motor drives the rotating part to rotate, the rotating part pushes and pulls the deflecting part through the sleeve rod, so that the deflecting rod connected to the U-shaped frame deflects around the axis, thereby driving the nozzle at the bottom of the fixed block on the left end of the deflecting rod to adjust the tilt angle. This structure breaks through the limitation of the traditional device "single fixed coating angle" and can accurately adapt to the surface coating requirements of complex-shaped metal workpieces such as arc and inclined surface, ensuring that all areas of the workpiece can be uniformly covered. At the same time, the device uses multiple structures The design ensures coating precision. On one hand, the scraper on the fixed rod below the front outer wall of the bracket can move synchronously with the bracket to smooth the coating liquid just sprayed on the workpiece surface in real time, effectively avoiding local accumulation or uneven thickness of the coating. On the other hand, the left and right clamping plates at the top of the base form a clamping structure. The left clamping plate is driven by the second lead screw by the third motor, which can stably fix workpieces of different sizes and prevent the workpieces from shifting during the coating process. When the bracket moves horizontally, the L-shaped block below the rear outer wall slides along the limiting rod in the limiting groove of the base, providing precise guidance for the bracket and ensuring that the nozzle always moves along the preset trajectory, thus ensuring the final coating quality.

[0015] (2) The coating device for metal surface treatment with good cooling effect adopts a dual cooling structure of active air cooling by fan and condensation at the bottom of condenser tube. The air cooling directly acts on the coating surface, and the condensation conducts the cold energy from the bottom of the workpiece. The dual action greatly accelerates the cooling speed, solving the problem of slow cooling and efficiency restriction of traditional devices. The condenser tube and the mounting groove are both designed in an S shape, which can increase the contact area between the condenser tube and the base, so that the cold energy is evenly distributed on the surface of the base. Combined with the fan blowing evenly on the coating surface, it avoids local cooling that is too fast or too slow, effectively preventing the coating from cracking, peeling and other quality defects due to uneven cooling, and ensuring the final quality of metal surface treatment.

[0016] Furthermore, the support is limited by the L-shaped block and the limit rod when it moves to prevent the support from shifting. The deflection rod is rotatably connected to the U-shaped frame, and the sleeve rod is movably connected to the rotating and deflection parts. The clearance between each component is reasonable, and there is no jamming or shaking during operation, ensuring the long-term stable use of the device. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Example 1: A coating device for metal surface treatment with good cooling effect. Through the coordinated action of components such as rotating part 14, sleeve rod 141, deflecting rod 15 and deflecting part 16, the spraying angle of the nozzle 152 is adjusted. Then, through the threaded connection between the first lead screw 11 and the first slider, the horizontal position of the nozzle 152 is adjusted. This prevents poor coating effect, which not only has a single coating angle and is difficult to adapt to the surface treatment needs of complex workpieces, but also requires multiple manual operations during coating adjustment, which increases labor intensity and affects processing efficiency and consistency.

[0021] like Figure 1 - Figure 4As shown, a coating device for metal surface treatment with good cooling effect includes a base 1, which serves as the basic support component of the device, providing a load-bearing foundation for the stable operation of the entire device. A first groove is formed at the rear of the top of the base 1, and a first lead screw 11 is rotatably connected in the first groove. A first motor is fixedly connected to the left end of the first lead screw 11. When the first motor is started, its output end can directly drive the first lead screw 11 to rotate stably in the first groove at the rear of the top of the base 1. A first slider is threadedly connected to the first lead screw 11, and a bracket 12 is fixedly connected to the top of the first slider. Since the first lead screw 11 and the first slider are threadedly connected, and the top of the first slider is fixedly connected to the bracket 12, the rotation of the first lead screw 11 will transform into the horizontal line of the first slider. The movement of the support 12 causes it to move smoothly along the slide groove. Simultaneously, a limiting groove is provided behind the first slide groove at the top of the base 1, with a limiting rod fixedly connected within it. An L-shaped block is also fixedly connected to the lower part of the rear outer wall of the support 12, and this L-shaped block is movably connected to the limiting rod. The L-shaped block on the lower part of the rear outer wall of the support 12 slides synchronously along the limiting rod in the limiting groove of the base 1, forming a double guiding constraint. This completely prevents the support 12 from shifting or wobbling during movement, ultimately achieving precise horizontal adjustment of subsequent components linked to the support 12. This allows for flexible adaptation to the full-surface coating requirements of metal workpieces of different lengths. A U-shaped frame 13 is fixedly connected to the support 12, providing mounting support for the upper components. The top of the U-shaped frame 13 is fixedly connected to... A second motor is connected to the U-shaped frame 13. A deflector rod 15 is rotatably connected to the U-shaped frame 13. A fixing block 151 is fixedly connected to the left end of the deflector rod 15. A nozzle 152 is fixedly connected to the bottom of the fixing block 151. A deflector component 16 is fixedly connected to the deflector rod 15, and the deflector component 16 is movably connected to the sleeve rod 141. The sleeve rod 141 is movably connected to the side of the rotating component 14 away from the output end of the second motor. The output end of the second motor passes through the top of the U-shaped frame 13, and the rotating component 14 is fixedly connected to the output end of the second motor. When the second motor at the top of the U-shaped frame 13 is started, its output end passes through the top of the U-shaped frame 13, directly driving the rotating component 14 to rotate around the motor output shaft. Because the side of the rotating component 14 away from the motor output end is movably connected to the sleeve rod 141, the rotating component 14... During rotation, the sleeve rod 141 exerts a pushing and pulling force on the deflecting component 16 fixed on the deflecting rod 15. Since the deflecting rod 15 and the U-shaped frame 13 are rotatably connected, the deflecting component 16, under force, will cause the deflecting rod 15 to deflect around the rotation point, thereby causing the nozzle 152 at the bottom of the left end fixing block 151 of the deflecting rod 15 to adjust its tilt angle synchronously. This can precisely adapt to the surface coating requirements of workpieces with complex shapes such as arcs and slopes, ensuring that irregular areas of the workpiece can also be effectively covered. A fixing rod 17 is also fixedly connected to the lower part of the front outer wall of the bracket 12, and a scraper 171 is fixedly connected to the fixing rod 17. During the spraying of the coating liquid by the nozzle 152, the scraper 171 installed on the fixing rod 17 at the lower part of the front outer wall of the bracket 12 will move synchronously with the movement of the bracket 12.The freshly sprayed coating liquid on the workpiece surface is leveled in real time to remove excess liquid, ensuring a uniform coating thickness and preventing localized accumulation or uneven thickness. A storage tank 2 is fixedly connected to the bottom of the base 1, storing the coating liquid and providing a raw material supply for the coating operation. A pump body is fixedly connected to the rear of the storage tank 2, with a pipe fixedly connected to it. The end of the pipe is fixedly connected to the nozzle 152. When the pump body is activated, it stably delivers the coating liquid stored in the storage tank 2 to the nozzle 152 through a dedicated pipe. The nozzle 152 then evenly sprays the coating liquid onto the metal workpiece surface according to preset parameters.

[0022] Example 2: Unlike Example 1, the horizontal position of the left clamping plate 31 is adjusted by the threaded connection between the second lead screw 3 and the second slider, which works in conjunction with the right clamping plate to fix and hold the metal part. The fan 153 at the bottom of the fixing block 151 is used to cool the coating liquid sprayed from the nozzle 152. The condenser tube 34 is installed through the mounting groove 33. The S-shaped distribution of the condenser tube 34 is used to improve the cooling effect of the condenser tube 34 and prevent poor cooling performance. Slow cooling speed directly restricts the overall efficiency of metal surface treatment, and uneven cooling can easily lead to quality defects such as cracking and peeling of the coating, which seriously affects the final quality of metal surface treatment.

[0023] like Figure 5 - Figure 6As shown, a fan 153 is fixedly connected to the bottom of the fixing block 151, and the fan 153 faces the nozzle 152. Its working principle is that when the nozzle 152 sprays the coating liquid onto the workpiece surface, the fan 153 starts and blows uniform cold air onto the newly formed coating surface. The cold air can quickly remove the heat from the coating surface, perform preliminary cooling of the coating, and accelerate the curing of the coating surface. A second sliding groove is provided on the left side of the top front of the base 1. A second lead screw 3 is rotatably connected in the second sliding groove. A third motor is fixedly connected to the left end of the second lead screw 3. A second slider is threadedly connected, and a left clamping plate 31 is fixedly connected to the top of the second slider. A right clamping plate is fixedly connected to the right side of the top of the base 1. The working principle is that starting the third motor will drive the second lead screw 3 in the second slide groove at the front of the top of the base 1 to rotate at a constant speed. Since the second lead screw 3 and the second slider are threadedly connected, and the top of the second slider is fixedly connected to the left clamping plate 31, the rotational motion of the second lead screw 3 can be converted into the horizontal linear motion of the second slider, thereby driving the left clamping plate 31 to move towards the workpiece side along the slide groove until the left clamping plate 31 and the right clamping plate fixed on the right side of the base 1 together form a stable clamp for the workpiece. The clamping force of the two clamping plates firmly fixes the workpiece, effectively preventing the workpiece from shifting or shaking during the subsequent coating process, providing a basic guarantee for the subsequent coating accuracy. A placement frame 32 is fixedly connected to the top of the base 1. Its working principle is to place the metal workpiece to be processed stably. With the positioning function of the placement frame 32, it is ensured that the bottom of the workpiece is completely attached to the surface of the base 1, avoiding tilting of the workpiece during initial placement. An installation groove 33 is opened on the top of the base 1, and an installation groove 33 is embedded in the installation groove 33. The condenser tube 34, and the mounting groove 33 and the condenser tube 34 are both S-shaped. The working principle is that after the coolant or other condensing medium is introduced into the condenser tube 34, the condenser tube 34 will transfer the cold energy to the bottom of the workpiece through the base 1, and cool the coating film at low temperature from the bottom of the workpiece. This forms a synergistic effect of synchronous cooling from top to bottom with the cooling method of the fan 153. This can not only greatly improve the cooling efficiency, but also ensure that the coating film is heated evenly. It can completely avoid quality problems such as coating cracking and peeling caused by local overheating or differences in cooling rate, and ensure the final quality of the coating film on the metal surface.

[0024] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] 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.
