[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Specific implementation examples are given below.
[0023] like Figures 1 to 3 As shown in the embodiment of this utility model, a batch spraying device for injection molded parts includes a base plate 1; a support leg 11 is fixedly connected to the top of the base plate 1; a worktable 12 is fixedly connected to the top of the support leg 11; a conveying assembly is installed in the middle of the worktable 12; two symmetrically arranged first telescopic rods 13 are fixedly connected to the top of the worktable 12 away from the conveying assembly; a first support plate 14 is fixedly connected to the top of the first telescopic rods 13; a plurality of equidistantly distributed connecting rods 15 are fixedly connected to the bottom of the first support plate 14; the connecting rods 15 are located away from the... An adjusting cylinder 16 is rotatably connected to the end of the first support plate 14; a steel rope 17 is rotatably connected to the middle of the adjusting cylinder 16; two symmetrically arranged second telescopic rods 19 are fixedly connected to the top of the workbench 12 near the top of the first telescopic rod 13; a second support plate 110 is fixedly connected to the top of the second telescopic rods 19; two symmetrically arranged liquid storage tanks 111 are fixedly connected to the top of the second support plate 110; a liquid storage pipe 112 is fixedly connected to the bottom of the liquid storage tanks 111 and passes through the second support plate 110; a steel rope 17 is rotatably connected to the middle of the second support plate 110. The moving connection has multiple symmetrically arranged atomizing nozzles 18; the end of the steel rope 17 away from the adjusting cylinder 16 is fixedly connected to the atomizing nozzle 18; during operation, the injection molded part is transferred to the bottom of the atomizing nozzle 18 using the conveying assembly. Since the connecting rod 15 and the adjusting cylinder 16 are threadedly connected, rotating the adjusting cylinder 16 clockwise causes the steel rope 17 to wind around the middle of the adjusting cylinder 16, thus adjusting the angle of the atomizing nozzle 18 in the same direction, and vice versa. After adjusting the nozzle angle, the pressure pump in the middle of the liquid storage tank 111 is turned on. The pressure from the pressure pump allows the paint inside the storage tank 111 to be fed into the middle of the atomizing nozzle 18 through the storage pipe 112, spraying the injection molded parts on the top of the workbench 12. Through the above structure, the winding or releasing of the steel rope 17 can be easily controlled by rotating the adjusting cylinder 16, thereby precisely adjusting the angle of the nozzle and achieving continuous and fine angle adjustment to meet the spraying requirements of various injection molded parts. This ensures that the paint is sprayed onto the surface of the injection molded parts at the optimal angle and direction, ensuring that the paint is evenly covered on the surface of the injection molded parts and improving the spraying quality.
[0024] like Figures 1 to 2As shown, the conveying assembly includes a driven block 2; a drive block 26 is rotatably connected to the side wall of the worktable 12 away from the first telescopic rod 13; two symmetrically arranged driven blocks 2 are fixedly connected to the side wall of the worktable 12 near the drive block 26; a first belt 21 is rotatably connected to the middle of the drive block 26 and the driven block 2; a lead screw 23 is fixedly connected to the middle of both the drive block 26 and the driven block 2, and passes through the worktable 12; a slider 24 is slidably connected to the middle of the lead screw 23; a suction cup 25 is fixedly connected to the top of the slider 24; a first motor 22 is rotatably connected to the side wall of the drive block 26; during operation, the... After the injection molded part is placed on top of the suction cup 25, the first motor 22 is turned on. The output end of the first motor 22 drives the drive block 26 to rotate. The rotation of the drive block 26 drives the first belt 21 and the driven block 2 to rotate. At this time, the suction cup 25 in the middle of the lead screw 23 also slides along the fixed trajectory, which can convey the injection molded part to the bottom of the atomizing nozzle 18 for spraying. Through the above structure, the accuracy of the spraying position can be ensured, ensuring that each injection molded part can be sprayed evenly and consistently, improving the stability of the spraying quality, and reducing paint waste and product defects caused by position deviation.
[0025] like Figure 4 As shown, two symmetrically arranged fixed blocks 3 are fixed to the top of the worktable 12 away from the first motor 22; a third support plate 31 is fixed to the top of the fixed blocks 3; multiple pulleys 32 distributed at equal intervals are rotatably connected to the top of the third support plate 31; a second belt 34 is rotatably connected to the middle of the pulleys 32; a second motor 36 is rotatably connected to the top of the pulleys 32 and is located in the middle; a rotating rod 33 is fixed to the bottom of the pulleys 32; multiple fan blades 35 distributed at equal intervals are fixed to the middle of the rotating rod 33; during operation, after the injection molded part is sprayed, the slider 24 and the suction cup 25 can remove the injection molded part. When the plastic part is delivered to the bottom of the fan blade 35, the second motor 36 is turned on. The output of the second motor 36 drives the second belt 34 and the pulley 32 to rotate synchronously. The rotation of the pulley 32 drives the rotating rod 33 to rotate. When the rotating rod 33 rotates, the fan blade 35 generates airflow, which can quickly dry the sprayed injection molded part. Through the above structure, the airflow generated by the fan blade 35 can accelerate the airflow, which helps the coating on the surface of the injection molded part to dry evenly, making the coating smoother and more even, improving the appearance quality and performance of the coating, and reducing problems such as flow marks and blistering on the coating surface caused by uneven drying.
[0026] like Figures 1 to 2As shown, the worktable 12 has multiple equally spaced grooves in the middle near the second telescopic rod 19; two symmetrically arranged springs 4 are fixed in the middle of the grooves; clamping plates 41 are fixed to the ends of the springs 4; a guide plate 42 is hinged to the side wall of the clamping plate 41 near the suction cup 25; during operation, when the injection molded part on the top of the suction cup 25 contacts the guide plate 42, the guide plate 42 will rotate under the force of the injection molded part, pushing the clamping plate 41 away. At this time, the springs 4 are compressed. When the injection molded part leaves the clamping plate 41, the springs 4 release their elastic potential energy, pushing the clamping plate 41 back to its initial position. Through the above structure, the cooperation of the clamping plate 41 and the guide plate 42 can realize the automatic diversion of the injection molded part, adapting to different production process requirements. The springs 4 can play a buffering role, avoiding damage to the injection molded part due to excessive impact force, and protecting the quality and integrity of the injection molded part.
[0027] like Figure 4 As shown, a placement rack 5 is slidably connected to the top of the base plate 1; a caster wheel 51 is rotatably connected to the bottom of the placement rack 5; during operation, the injection molded parts to be sprayed and the sprayed injection molded parts can be placed on the top of the placement rack 5 to ensure that they will not be damaged due to unstable placement during storage before and after spraying. The sliding design makes loading and unloading of injection molded parts and transfer between different work areas more convenient and efficient. Through the above structure, manual handling and waiting time can be effectively reduced, which helps to realize the automation process of batch spraying operations, thereby improving the overall production efficiency.
[0028] like Figure 2 As shown, a protective pad 6 is fixed to the side wall of the clamping plate 41 away from the spring 4; the protective pad 6 is made of rubber; during operation, when the injection molded part comes into contact with the clamping plate 41, the protective pad 6 can play a buffering role, and the protective pad 6 prevents the injection molded part from being damaged by collision. Through the above structure, the problem of scratches or wear on the surface of the injection molded part can be effectively reduced, which helps to maintain the appearance quality and integrity of the injection molded part.
[0029] like Figure 4 As shown, a protective plate 7 is fixed to the top of the placement rack 5; during operation, it can prevent the injection molded parts from colliding or rubbing against the placement rack 5 during placement or sliding, and avoid scratches, wear and other damage to the surface of the injection molded parts. Through the above structure, the protective plate 7 can also play a certain role in buffering and shock absorption, reducing the risk of damage or displacement of the injection molded parts due to vibration.
[0030] During operation, the injection molded part is transferred to the bottom of the atomizing nozzle 18 using the conveying assembly. Since the connecting rod 15 and the adjusting cylinder 16 are threadedly connected, rotating the adjusting cylinder 16 clockwise causes the steel rope 17 to wind around the middle of the adjusting cylinder 16, thus adjusting the angle of the atomizing nozzle 18 in the same direction. Turning it counter-clockwise adjusts the angle in the opposite direction. After adjusting the nozzle angle, the pressure pump in the middle of the liquid storage tank 111 is turned on. The pressure from the pressure pump forces the coating inside the liquid storage tank 111 through the liquid storage pipe 112 to the middle of the atomizing nozzle 18, thus atomizing the injection molded part at the top of the worktable 12. For spraying the plastic part, after placing the injection molded part on top of the suction cup 25, the first motor 22 is turned on. The output end of the first motor 22 drives the drive block 26 to rotate. The rotation of the drive block 26 drives the first belt 21 and the driven block 2 to rotate. At this time, the suction cup 25 in the middle of the lead screw 23 also slides along the fixed trajectory, which can convey the injection molded part to the bottom of the atomizing nozzle 18 for spraying. After the injection molded part is sprayed, the slider 24 and the suction cup 25 can send the injection molded part to the bottom of the fan blade 35. At this time, the second motor 36 is turned on. The output end drives the second belt 34 and pulley 32 to rotate synchronously. The rotation of pulley 32 drives the rotating rod 33 to rotate. When the rotating rod 33 rotates, it can generate airflow from the fan blade 35, which can quickly dry the sprayed injection molded parts. When the injection molded part on the top of the suction cup 25 contacts the guide plate 42, the guide plate 42 will rotate under the force of the injection molded part, pushing the clamping plate 41 away. At this time, the spring 4 is compressed. When the injection molded part leaves the clamping plate 41, the spring 4 releases its elastic potential energy, pushing the clamping plate 41 back to its initial position, so that the parts that need to be dried can be dried. The sprayed injection molded parts and the finished sprayed injection molded parts are placed on top of the placement rack 5 to ensure that they will not be damaged due to unstable placement during storage before and after spraying. The sliding design makes loading and unloading of injection molded parts and transfer between different working areas more convenient and efficient. When the injection molded parts come into contact with the clamping plate 41, the protective pad 6 can play a buffering role. The protective pad 6 prevents the injection molded parts from being damaged by collision. It can prevent the injection molded parts from colliding or rubbing against the placement rack 5 during placement or sliding, and avoid scratches, wear and other damage to the surface of the injection molded parts.
