Description

Technical Field

[0001] This utility model relates to the field of paint spraying technology, specifically a paint spraying device with purification function. Background Technology

[0002] In paint spraying operations, the quality and uniformity of the paint play a crucial role in the spraying effect.

[0003] However, paint is prone to sedimentation during storage. Since paint typically contains various pigments, fillers, and other solid components, these components gradually settle at the bottom of the paint can under gravity, causing the paint to separate. When spraying, directly using this sedimented and separated paint will result in uneven color and inconsistent thickness in the sprayed coating, severely affecting the spraying quality and product appearance. Furthermore, impurities such as residues from the production process and dust from transportation and storage can contaminate the paint. These impurities can clog the spray gun, affecting the smoothness of spraying and even damaging the spraying equipment. Therefore, a paint spraying device with a purification function is proposed to solve the above problems. Utility Model Content

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.

[0023] Please see Figures 1 to 4 In this embodiment, a paint spraying device with a purification function includes a base 1, a paint tank 2 and a spray gun 3. A filter screen 4 is fixedly connected to the inside of the paint tank 2, and an auxiliary component for assisting spraying is provided on the top of the paint tank 2.

[0024] Please see Figure 1 In this embodiment, the auxiliary components include a motor 5 fixedly connected to the top of the paint tank 2, a connecting rod 6 fixedly connected to the output shaft of the motor 5, a turntable 7 fixedly connected to the bottom end of the connecting rod 6, a scraper 8 fixedly connected to the bottom of the turntable 7, a transmission gear 9 fixedly connected to the outer side of the connecting rod 6, a driven gear 10 meshing with the right side of the transmission gear 9, a rotating rod 11 fixedly connected to the inner side of the center of the driven gear 10, a transmission wheel 12 fixedly connected to the right end of the rotating rod 11, a transmission belt 13 drivingly connected to the outer surface of the transmission wheel 12, a driven wheel 14 drivingly connected to the bottom end of the transmission belt 13, a mounting rod 15 fixedly connected to the inner side of the center of the driven wheel 14, and a stirring paddle 16 fixedly connected to the outer side of the mounting rod 15.

[0025] Specifically, four corners of the bottom of the base 1 are fixedly connected to movable wheels 17, and each movable wheel 17 is equipped with a brake.

[0026] It should be noted that the brake is used to ensure that the device is stably stopped when spraying is required in a fixed position, so as to avoid affecting the spraying accuracy and work safety due to accidental movement.

[0027] Specifically, a pusher 18 and a material pump 19 are fixedly connected to the top of the base 1. A material pump 20 is fixedly connected to the material pump 19 at the material pump end, and the other end of the material pump 20 is fixedly connected to the paint tank 2. A discharge pipe 21 is fixedly connected to the material pump 19 at the discharge end, and the other end of the discharge pipe 21 is fixedly connected to the spray gun 3.

[0028] Specifically, a mounting shell 22 is fixedly connected to the top of the base 1, an electric push rod 23 is fixedly connected to the inner bottom wall of the mounting shell 22, a mounting bracket 24 is fixedly connected to one end of the movable rod of the electric push rod 23, and the spray gun 3 is fixedly connected to the inner side of the mounting bracket 24.

[0029] It should be noted that the design of the mounting shell 22 not only provides a stable mounting base for the electric push rod 23, but also provides a certain degree of protection for the electric push rod 23, preventing it from being damaged by external impacts and dust. The electric push rod 23 is used to adjust the height of the spray gun 3, thereby enhancing its flexibility.

[0030] Specifically, a filling port is provided on the top of the inner side of the paint tank 2, and a cap that matches the filling port is provided on the top of the paint tank 2.

[0031] It should be noted that the cap effectively prevents paint leakage and external impurities from entering the paint container 2, ensuring the purity and quality of the paint.

[0032] Specifically, a protective shell 25 is fixedly connected to the inner top wall of the paint tank 2, and the transmission gear 9 and the driven gear 10 are both located inside the protective shell 25.

[0033] It should be noted that the protective shell 25 is made of lightweight plastic material, which has good insulation and corrosion resistance, effectively preventing the coating from affecting the transmission performance of the gears.

[0034] Specifically, the inner side of the turntable 7 has several openings, and the scraper 8 contacts the filter screen 4.

[0035] It should be noted that the nozzle is used for the coating to pass through the turntable 7, and the scraper 8 is used to effectively remove impurities and deposits from the surface of the filter screen 4.

[0036] Specifically, the left end of the mounting rod 15 passes through the right side wall of the paint tank 2 and the mounting port of the agitator 16 in sequence, and is rotatably connected to the inner left side wall of the paint tank 2.

[0037] The working principle of the above embodiments is as follows:

[0038] The paint is stored in the paint tank 2. When the paint passes through the filter screen 4, the filter screen 4 will intercept larger particles, impurities, and sediments in the paint to achieve purification filtration. After the motor 5 is started, its output shaft drives the connecting rod 6 to rotate. The connecting rod 6 drives the turntable 7 to rotate. The scraper 8 at the bottom of the turntable 7 contacts the surface of the filter screen 4. During the rotation of the turntable 7, the scraper 8 continuously scrapes off the impurities intercepted on the filter screen 4 to prevent the filter screen 4 from clogging and ensure that the filtration function of the filter screen 4 is continuously effective.

[0039] When the motor 5 rotates, the transmission gear 9 on the connecting rod 6 rotates accordingly. The transmission gear 9 meshes with the driven gear 10, driving the driven gear 10 to rotate. A rotating rod 11 is fixedly connected to the inner side of the center of the driven gear 10. The rotating rod 11 drives the transmission wheel 12 to rotate. The transmission wheel 12 drives the driven wheel 14 to rotate through the transmission belt 13. An installation rod 15 is fixedly connected to the inner side of the center of the driven wheel 14. The installation rod 15 drives the stirring paddle 16 to rotate inside the paint tank 2. The rotation of the stirring paddle 16 causes strong convection and stirring of the paint in the paint tank 2, which re-stirs the paint that has settled at the bottom of the tank evenly, preventing the paint from settling and separating due to long-term standing, and ensuring that the paint has a uniform texture and performance during the spraying process.

[0040] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
