Description

Technical Field

[0001] The present invention relates to the technical field of core spraying, and specifically to a spraying device for an environmentally friendly vehicle-mounted coated core. Background Art

[0002] The spraying device for an environmentally friendly vehicle-mounted coated core usually consists of parts such as a spraying table, a movable support plate, a fixing device, and a control device, and usually sprays on canned cores with uniform sizes.

[0003] The patent with the patent announcement number CN222000413U relates to a paint spraying device for core production, belonging to the technical field of paint spraying devices. It includes a mounting frame. The top of the mounting frame is fixedly connected with a mounting box. Two corresponding first rotating disks are rotatably connected inside the mounting box. A connecting pipe is fixedly connected inside the first rotating disk. A plurality of paint spraying pipes are fixedly connected inside the connecting pipe. Two corresponding connecting blocks are fixedly connected to the top of the mounting box. A first transmission mechanism is arranged inside the connecting block. Two corresponding second rotating disks are rotatably connected inside the mounting box. Two corresponding electric telescopic rods are fixedly installed inside the second rotating disk. The output end of the electric telescopic rod is fixedly connected with a clamping block. The beneficial effect of this patent is that through the mutual cooperation of two groups of first transmission mechanisms, the first rotating disk, the connecting pipe, the paint spraying pipe, the paint can, the conveying pipe, and the pressure pump, the core can be evenly painted.

[0004] In the above patent, through the mutual cooperation of two groups of first transmission mechanisms, the first rotating disk, the connecting pipe, the paint spraying pipe, the paint can, the conveying pipe, and the pressure pump, the core can be evenly painted. However, it is difficult to avoid the agglomeration of excess paint, which affects the fixing effect of the core. The agglomerated paint will increase the gap between the core and the sliding disk, making the core prone to shaking during the spraying process, thus affecting the uniformity and integrity of the coating. Therefore, it is very necessary to design a spraying device for an environmentally friendly vehicle-mounted coated core with strong practicability and preventing the agglomeration of excess paint from affecting the fixing of the core. Summary of the Invention

[0005] The purpose of the present invention is to provide a spraying device for an environmentally friendly vehicle-mounted coated core to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: A spraying device for an environmentally friendly vehicle-mounted coated iron core, including a spraying table and spraying equipment, further comprising a placement module, a load-bearing module, and a liquid return module. The spraying equipment is arranged on the top of the spraying table. A spraying plate is fixedly installed on the top of the spraying table. A sliding rod penetrates through the right side of the spraying plate. A sliding plate is fixedly installed on the left side of the sliding rod. A sliding groove is opened on the left side of the sliding plate. A U-shaped plate is slidably installed on the front and rear walls of the sliding plate. The placement module includes a sliding disk, an activity groove, an activity plate, a limiting groove, a sliding frame, a rotating rod, and a sliding disk. The sliding disk is rotatably installed on the left side of the U-shaped plate. The activity groove is opened on the top of the spraying table. A material collection groove is opened on the top of the spraying table. The activity plate is slidably installed on the inner wall of the material collection groove. The limiting groove is opened on the top of the activity plate. The sliding frame is fixedly installed on the top of the spraying table. The rotating rod rotatably penetrates through the left and right walls of the sliding frame. The sliding disk is fixedly installed on the right side of the rotating rod. An adsorption frame is slidably installed on the inner wall of the material collection groove. A magnet is fixedly installed on the top of the adsorption frame. When the U-shaped plate sways to the left, it drives the sliding disk to sway, and the sliding disk sways to shake off the excess paint on its left side, thereby preventing the excess paint from caking and affecting the fixation of the iron core.

[0007] According to the above technical solution, an activity support plate is fixedly installed on the left side of the sliding plate. The sliding plate abuts against the activity plate. A first spring is arranged between the sliding plate and the U-shaped plate. When the U-shaped plate moves to the right, it pulls the first spring. The first spring deforms and stores energy under the pull of the U-shaped plate. After the U-shaped plate moves to the right and disengages from the contact with the iron core, the first spring can drive the U-shaped plate to return to its initial position.

[0008] According to the above technical solution, a second spring is arranged between the activity plate and the activity groove. When the activity plate moves downward, it squeezes the second spring. The second spring deforms and stores energy under the squeeze of the activity plate. After the U-shaped plate is aligned with the limiting groove, the second spring can drive the activity plate to return to its initial position. The activity support plate contacts the top of the spraying table. The activity plate contacts the inner wall of the activity groove. The activity plate moves upward under the elastic force of the second spring, and the upward movement of the activity plate causes the sliding plate to contact the limiting groove and be limited by the activity plate.

[0009] According to the above technical solution, the load-bearing module is used to lift the iron core, and the liquid return module is used to recover the coating. The load-bearing module includes an adsorption spring, a lifting plate, and a lifting rod. The magnet moves downward to disengage from the contact with the iron core, and the magnet moves downward to disengage from the contact with the iron core, thereby ensuring that the iron core will not be blocked by the magnet during spraying. The adsorption spring is arranged between the adsorption frame and the material receiving groove. The lifting plate is fixedly installed on the inner wall of the adsorption frame, and the lifting rod is fixedly installed at the bottom of the adsorption frame. The adsorption frame moves downward to squeeze the adsorption spring, and the adsorption spring deforms and stores energy under the extrusion of the adsorption frame. After the sliding plate disengages from the contact with the lifting plate, the adsorption spring can drive the adsorption frame to return to the initial position.

[0010] According to the above technical solution, the top of the lifting plate is set as an inclined surface, the magnet is set as an arc, and the lifting rod is elastic. The adsorption frame moves upward to drive the magnet to move upward, and the magnet moves upward to carry the iron core after spraying.

[0011] According to the above technical solution, the liquid return module includes a liquid return hole, a separation frame, a separation groove, a liquid return rod, and a liquid return plate. The liquid return plate moves back and forth to press and break the caked coating on the top of the separation frame. The liquid return hole is opened at the bottom of the material receiving groove. The separation frame is fixedly installed on the inner wall of the liquid return hole. The separation groove is opened at the top of the separation frame. The liquid return rod slides through the top of the separation groove, and the liquid return plate is fixedly installed on the top of the liquid return rod.

[0012] According to the above technical solution, the liquid return module further includes a liquid return spring, an elastic telescopic rod, and a liquid injection hole. The liquid return spring is arranged between the separation groove and the liquid return plate. The liquid return plate moves downward to squeeze the liquid return spring, and the liquid return spring deforms and stores energy under the extrusion of the liquid return plate. After the liquid return plate disengages from the contact with the adsorption frame, the liquid return spring can drive the liquid return plate to return to the initial position. The elastic telescopic rod is fixedly installed at the bottom of the inner wall of the material receiving groove, and the liquid injection hole is opened on the circumferential surface of the elastic telescopic rod.

[0013] According to the above technical solution, a rubber ring is arranged between the free end and the fixed end of the elastic telescopic rod. A fatty hydrocarbon solvent is arranged inside the elastic telescopic rod. A rubber valve is arranged on the inner wall of the liquid injection hole. The rubber valve of the liquid injection hole deforms under the extrusion of the fatty hydrocarbon solvent, and the deformation of the rubber valve releases the seal of the liquid injection hole.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) The spraying device of the environmentally friendly vehicle-mounted coated iron core moves the movable plate upward so that the sliding plate contacts the limiting groove and is limited by the movable plate. By limiting the sliding plate, the outer wall of the can-shaped iron core can be evenly supported to avoid deformation due to excessive force when the sliding plate fixes the iron core, thereby ensuring that the coating adhesion and appearance quality meet the standards. The sliding plate shakes off the excess paint on the left side of itself, thereby preventing the excess paint from agglomerating and affecting the fixation of the iron core, reducing the shaking of the iron core caused by the agglomeration of the paint, and improving the surface flatness of the iron core coating, thereby reducing the rework rate of the iron core spraying.

[0015] (2) The spraying device for the environmentally friendly vehicle-mounted coated iron core moves the magnet downward to break contact with the iron core, thereby ensuring that the iron core will not be blocked by the magnet during spraying. After the magnet breaks contact with the iron core, the circumferential surface of the iron core can be completely exposed to the spraying range of the spraying equipment, avoiding the problem of too thin coating caused by blocking the magnet, thereby ensuring that the circumferential surface of the iron core is evenly covered with the coating.

[0016] (3) The spraying device for the environmentally friendly vehicle-mounted coated iron core supports the iron core after spraying by moving the magnet upward to prevent the iron core from slipping after spraying. When the magnet adsorbs the supporting iron core upward, it can evenly apply force to fix its position, avoiding scratches on the iron core coating caused by collision and slipping, thereby ensuring the integrity of the coating.

[0017] (4) The spraying device of the environmentally friendly vehicle-mounted coated iron core drives the iron core and the sliding plate to rotate together through the rotation of the sliding plate. When the iron core rotates, the magnet absorbs the iron slag adhered to the surface of the iron core. The residual iron slag on the surface of the iron core will cause the coating to have problems such as bulges or insufficient adhesion. Timely removal of the iron slag can avoid the formation of granular defects after the coating is cured and improve the spraying effect of the spraying equipment.

[0018] (5) The spraying device of the environmentally friendly vehicle-mounted coated iron core presses and breaks the paint agglomerated on the top of the separation frame through the reciprocating movement of the liquid return plate. The agglomerated paint is converted into flowable fine particles or liquid through the pressing and breaking of the liquid return plate, thereby avoiding large pieces of paint from being discarded due to inability to be processed, thereby improving the paint recovery efficiency and meeting the environmentally friendly production requirements.

[0019] (6) The spraying device of the environmentally friendly vehicle-mounted coating core releases the seal of the injection hole by deforming the rubber valve. The rated aliphatic hydrocarbon solvent inside the elastic telescopic rod enters the receiving tank through the injection hole to mix with the waste paint. The rapid switching of the rubber valve between sealing and opening can avoid the leakage or volatilization of the aliphatic hydrocarbon solvent. The timely injection of the aliphatic hydrocarbon solvent prevents the waste paint from drying up again in the receiving tank, thereby greatly shortening the paint recovery time.

Detailed implementation manners

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1:

[0023] Please refer to Figure 1-7, the present invention provides a technical solution: an environmentally friendly spraying device for a vehicle-mounted coated iron core, including a spraying table 1 and spraying equipment, further including a placement module, a load-bearing module, and a liquid return module. The spraying equipment is arranged on the top of the spraying table 1. A spraying plate 2 is fixedly installed on the top of the spraying table 1. A sliding rod 3 penetrates through the right side of the spraying plate 2. A sliding plate 4 is fixedly installed on the left side of the sliding rod 3. A sliding groove 5 is opened on the left side of the sliding plate 4. A U-shaped plate 6 is slidably installed on the front and rear walls of the sliding plate 4. The placement module includes a sliding disk 7, a moving groove 8, a moving plate 9, a limiting groove 10, a sliding frame 12, a rotating rod 13, and a sliding disk 14. The sliding disk 7 is rotatably installed on the left side of the U-shaped plate 6. The moving groove 8 is opened on the top of the spraying table 1. A material receiving groove 151 is opened on the top of the spraying table 1. The moving plate 9 is slidably installed on the inner wall of the material receiving groove 151. The limiting groove 10 is opened on the top of the moving plate 9. The sliding frame 12 is fixedly installed on the top of the spraying table 1. The rotating rod 13 rotatably penetrates through the left and right walls of the sliding frame 12. The sliding disk 14 is fixedly installed on the right side of the rotating rod 13. An adsorption frame 152 is slidably installed on the inner wall of the material receiving groove 151. A magnet 154 is fixedly installed on the top of the adsorption frame 152. By shaking the sliding disk 7, the excess paint on its left side is shaken off, thereby preventing the excess paint from caking and affecting the fixation of the iron core, reducing the shaking of the iron core caused by the caking of the paint, improving the flatness of the surface of the iron core coating, and thus reducing the rework rate of the iron core spraying.

[0024] A movable support plate 11 is fixedly installed on the left side of the sliding plate 4. The sliding plate 4 abuts against the moving plate 9. A first spring is arranged between the sliding plate 4 and the U-shaped plate 6. When the U-shaped plate 6 moves to the right, the first spring is pulled. The first spring deforms and stores energy under the pulling of the U-shaped plate 6. After the U-shaped plate 6 moves to the right and disengages from the contact with the iron core, the first spring can drive the U-shaped plate 6 to return to its initial position.

[0025] A second spring is arranged between the moving plate 9 and the moving groove 8. When the moving plate 9 moves downward, the second spring is compressed. The second spring deforms and stores energy under the compression of the moving plate 9. After the U-shaped plate 6 is aligned with the limiting groove 10, the second spring can drive the moving plate 9 to return to its initial position. The movable support plate 11 contacts the top of the spraying table 1. The moving plate 9 contacts the inner wall of the moving groove 8. The moving plate 9 moves upward under the elastic force of the second spring. The upward movement of the moving plate 9 causes the sliding plate 4 to contact the limiting groove 10 and be limited by the moving plate 9. By limiting the sliding plate 4, the outer wall of the can-shaped iron core can be evenly supported, avoiding deformation of the iron core due to excessive force when the sliding disk 7 fixes the iron core, so as to ensure that the coating adhesion and appearance quality meet the standards.

[0026] The paint in the existing solution is epoxy resin impregnating varnish, and the epoxy resin is diluted with alcohol or ethyl acetate. Now it is changed to water-based paint and diluted with pure water, thereby reducing the usage amount of alcohol or ethyl acetate.

[0027] The original epoxy resin usage amount in the existing solution: alcohol usage amount = 1:10. After changing to the water-based paint, epoxy resin: water = 1:10. By completely stopping the use of alcohol or ethyl acetate, both cost can be saved and environmental impact can be reduced.

[0028] During operation, after placing the iron core on the top of the adsorption frame 152, a linear motor is arranged on the right side of the sliding rod 3 and the output end of the linear motor is fixedly connected to the right side of the sliding rod 3. Start the linear motor to drive the sliding rod 3 to move towards the iron core. The movement of the sliding rod 3 towards the iron core drives the sliding plate 4 to move. The movement of the sliding plate 4 drives the U-shaped plate 6 to move. The movement of the U-shaped plate 6 towards the iron core drives the sliding disk 7 to move. The movement of the sliding disk 7 towards the iron core contacts the iron core and squeezes the iron core. The sliding disk 7 moves to the right under the reaction force of the squeezed iron core. The movement of the sliding disk 7 to the right drives the U-shaped plate 6 to move to the right. The U-shaped plate 6 gradually aligns with the limiting groove 10. After the U-shaped plate 6 aligns with the limiting groove 10, the movable plate 9 moves upward under the elastic force of the second spring. The upward movement of the movable plate 9 causes the sliding plate 4 to contact the limiting groove 10 and be limited by the movable plate 9. After the sliding plate 4 is limited by the movable plate 9, the sliding disk 7 cooperates with the sliding disk 14 to fix the iron core. After the iron core is fixed, a servo motor is arranged on the left side of the rotating rod 13 and the output end of the servo motor is fixed to the left side of the rotating rod 13. Start the servo motor to drive the rotating rod 13 to rotate. The rotation of the rotating rod 13 drives the sliding disk 14 to rotate. The rotation of the sliding disk 14 drives the iron core and the sliding disk 7 to rotate together. At the same time, start the spraying equipment to perform spraying operation on the iron core. After the spraying operation is completed, manually press the movable plate 9 to move downward. The downward movement of the movable plate 9 disengages from the contact with the sliding plate 4 and releases the limitation on the sliding plate 4. After the limitation of the sliding plate 4 is released, the linear motor drives the sliding rod 3 to move to the right to reset. The movement of the sliding rod 3 to the right to reset drives the sliding plate 4 and the U-shaped plate 6 to move to reset. The movement of the U-shaped plate 6 to the right disengages from the contact with the iron core. After the U-shaped plate 6 moves to the right and disengages from the contact with the iron core, the U-shaped plate 6 shakes to the left under the elastic force of the first spring. The shaking of the U-shaped plate 6 to the left drives the sliding disk 7 to shake. The shaking of the sliding disk 7 shakes off the excess paint on its left side, thereby preventing the excess paint from caking and affecting the fixation of the iron core. Embodiment 2:

[0029] Please refer to Figure 1-8, on the basis of the first embodiment, in this embodiment, the load-bearing module is used to lift the iron core, and the liquid return module is used to recycle the coating. The load-bearing module includes an adsorption spring 153, a lifting plate 155, and a lifting rod 156. The adsorption spring 153 is arranged between the adsorption frame 152 and the material receiving groove 151. The lifting plate 155 is fixedly installed on the inner wall of the adsorption frame 152, and the lifting rod 156 is fixedly installed at the bottom of the adsorption frame 152. When the adsorption frame 152 moves downward, it squeezes the adsorption spring 153. The adsorption spring 153 deforms and stores energy under the extrusion of the adsorption frame 152. After the sliding plate 4 disengages from the contact with the lifting plate 155, the adsorption spring 153 can drive the adsorption frame 152 to return to its initial position. After the magnet 154 disengages from the contact with the iron core, the circumferential surface of the iron core can be completely exposed within the spraying range of the spraying device, avoiding the problem of too thin coating caused by the shielding of the magnet 154, and thus ensuring that the circumferential surface of the iron core is evenly covered with the coating.

[0030] The top of the lifting plate 155 is set as an inclined surface, the magnet 154 is set as an arc, and the lifting rod 156 is elastic. When the adsorption frame 152 moves upward, it drives the magnet 154 to move upward. When the magnet 154 moves upward to carry the sprayed iron core, the iron core can be evenly stressed to fix its position, avoiding the scratching of the iron core coating caused by collision and slipping, and thus ensuring the integrity of the coating. And timely removal of iron slag can avoid the formation of granular defects after the coating is cured and improve the spraying effect of the spraying device.

[0031] The liquid return module includes a liquid return hole 161, a separation frame 162, a separation groove 163, a liquid return rod 164, and a liquid return plate 165. The liquid return hole 161 is opened at the bottom of the material receiving groove 151. The separation frame 162 is fixedly installed on the inner wall of the liquid return hole 161. The separation groove 163 is opened at the top of the separation frame 162. The liquid return rod 164 slides through the top of the separation groove 163, and the liquid return plate 165 is fixedly installed at the top of the liquid return rod 164. Through the pressing and crushing of the liquid return plate 165, the agglomerated coating will be transformed into flowable fine particles or liquid state, thereby avoiding the waste of large pieces of coating that cannot be processed, and thus improving the recycling efficiency of the coating to meet the requirements of environmentally friendly production.

[0032] The liquid return module further includes a liquid return spring 166, an elastic telescopic rod 167, and a liquid injection hole 168. The liquid return spring 166 is arranged between the separation groove 163 and the liquid return plate 165. When the liquid return plate 165 moves downward, it squeezes the liquid return spring 166. The liquid return spring 166 deforms and stores energy under the extrusion of the liquid return plate 165. After the liquid return plate 165 disengages from the contact with the adsorption frame 152, the liquid return spring 166 can drive the liquid return plate 165 to return to its initial position. The elastic telescopic rod 167 is fixedly installed at the bottom of the inner wall of the material receiving groove 151, and the liquid injection hole 168 is opened on the circumferential surface of the elastic telescopic rod 167.

[0033] A rubber ring is arranged between the free end of the elastic telescopic rod 167 and the fixed end of the elastic telescopic rod 167, and the rubber ring can increase the sealing between the free end of the elastic telescopic rod 167 and the fixed end of the elastic telescopic rod 167. An aliphatic hydrocarbon solvent is arranged inside the elastic telescopic rod 167, and a rubber valve is arranged on the inner wall of the liquid injection hole 168. The rubber valve of the liquid injection hole 168 is deformed by the squeezing of the aliphatic hydrocarbon solvent, and the deformation of the rubber valve releases the seal of the liquid injection hole 168. The rapid switching of the rubber valve between sealing and opening can avoid leakage or volatilization of the aliphatic hydrocarbon solvent, and the timely injection of the aliphatic hydrocarbon solvent can prevent the waste paint from drying up again in the receiving trough 151, thereby greatly shortening the paint recovery time.

[0034] During operation, the sliding plate 4 moves toward the direction close to the iron core, driving the movable support plate 11 to move. The movable support plate 11 moves and contacts the inclined surface at the top of the lifting plate 155 and squeezes the lifting plate 155. The lifting plate 155 moves downward due to the squeezing of the movable support plate 11. The lifting plate 155 moves downward, driving the adsorption frame 152 to move downward. The adsorption frame 152 moves downward, driving the magnet 154 to move downward. The magnet 154 moves downward and breaks away from the contact with the iron core. The magnet 154 moves downward and breaks away from the contact with the iron core, thereby ensuring that the iron core will not be blocked by the magnet 154 during spraying, thereby ensuring the integrity of the iron core spraying area. After the spraying operation of the spraying equipment is completed, the linear motor is started to drive the sliding rod 3 to move in the direction away from the magnet 154. The sliding rod 3 moves in the direction of the magnet 154 with The movable sliding plate 4 moves to reset, and the sliding plate 4 moves to reset and disengages from the contact with the lifting plate 155. After the sliding plate 4 disengages from the contact with the lifting plate 155, the adsorption frame 152 moves upward under the elastic force of the adsorption spring 153, and the adsorption frame 152 moves upward to drive the magnet 154 to move upward. The magnet 154 moves upward to support the iron core after spraying to prevent the iron core from slipping after spraying. At the same time, after the iron core is fixed, a servo motor is provided on the left side of the rotating rod 13 and the output end of the servo motor is fixed to the left side of the rotating rod 13. The servo motor is started to drive the rotating rod 13 to rotate, and the rotation of the rotating rod 13 drives the sliding plate 14 to rotate. The rotation of the sliding plate 14 drives the iron core and the sliding plate 7 to rotate together. When the iron core rotates, the magnet 154 adsorbs the iron slag adhered to the surface of the iron core to improve the spraying effect of the iron core.

[0035] The adsorption frame 152 moves downward, driving the lifting rod 156 to move downward. The lifting rod 156 moves downward to contact and squeeze the liquid return plate 165. The liquid return plate 165 moves downward under the squeezing of the lifting rod 156. When the adsorption frame 152 moves upward under the elastic force of the adsorption spring 153, the adsorption frame 152 moves upward to reset and disengage from the contact with the liquid return plate 165. After the liquid return plate 165 is separated from the contact with the adsorption frame 152, the liquid return plate 165 moves upward under the elastic force of the liquid return spring 166. The liquid return plate 165 moves back and forth to press and break the paint agglomerated on the top of the separation frame 162. At the same time, the adsorption frame 152 moves downward to squeeze the free end of the elastic telescopic rod 167, and the elastic telescopic rod 167 is elastically retracted. The free end of the rod 167 is squeezed by the adsorption frame 152 and moves downward. The free end of the elastic telescopic rod 167 moves downward to squeeze the aliphatic hydrocarbon solvent inside the elastic telescopic rod 167. The aliphatic hydrocarbon solvent inside the elastic telescopic rod 167 is squeezed by the free end of the elastic telescopic rod 167 and enters the liquid injection hole 168. The aliphatic hydrocarbon solvent entering the liquid injection hole 168 squeezes the rubber valve of the liquid injection hole 168. The rubber valve of the liquid injection hole 168 is squeezed by the aliphatic hydrocarbon solvent and deformed. The deformation of the rubber valve releases the seal of the liquid injection hole 168. After the seal of the liquid injection hole 168 is released, the aliphatic hydrocarbon solvent inside the elastic telescopic rod 167 enters the receiving trough 151 through the liquid injection hole 168 and mixes with the waste paint.
