Description

Technical Field

[0001] The invention relates to the technical field of baking varnish coating production, in particular to a mixing device used for diluting amino baking varnish coating. Background Art

[0002] Amino paint is widely used in the fields of automobile, engineering machinery and aviation industry. Compared with traditional paint, amino paint has good weather resistance, chemical properties and scratch resistance. Amino paint is generally made of raw materials such as resin, additives, pigments and diluents. During its production process, it needs to go through mixing and grinding processes to achieve uniform mixing and suitable viscosity. The process flow is generally to stir the mixed raw materials evenly first, then send the mixed raw materials to the grinder for grinding to increase its viscosity, and finally add additives for stirring again. After reaching the specified performance, the finished product can be packaged.

[0003] Because the paint is sticky, it will adhere to the inner wall of the mixing container, the stirring equipment and the grinding equipment during the production process. Before the next production, the adhered paint needs to be cleaned to avoid affecting the subsequent products. The diluent that has a good cleaning effect on the adhered paint is its diluent, and the used diluent can be recycled again through the evaporation process. However, the current cleaning steps mostly use manual cleaning, which is not efficient. If the cleaning is not timely, the adhered paint will harden due to environmental factors, which increases the difficulty of cleaning.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please refer to the attached Figure 1 -Attached Figure 6The embodiment of the present invention provides a mixing device for diluting amino paint, including a base 1, a hydraulic turntable 2 is embedded in the middle of the base 1 and fixedly connected, a lifting device is fixedly connected to the rotating end of the hydraulic turntable 2, a transmission box 3 is arranged at the top of the lifting device, and the vertical axis of the middle of the transmission box 3 coincides with the rotating axis of the hydraulic turntable 2. The transmission box 3 is a cross-shaped structure, and its four corners are all arranged as rotating output ends, and a group of two symmetrical rotating output ends are respectively provided with a dispersing and stirring device, and another group of two symmetrical rotating output ends are respectively provided with a grinding device, and a spraying device is provided in the dispersing and stirring device and the grinding device for spraying a diluent, and the spraying device in the dispersing and stirring device rotates synchronously with the dispersing and stirring device. The base 1 is also a cross-shaped structure, and processing tanks 4 are respectively arranged at its four corners, and the processing tanks 4 correspond to the dispersing and stirring device and the grinding device one by one, respectively. One group of two symmetrical processing tanks 4 is used to load mixed raw materials, and a feeding device is arranged on the outside, and another group of two symmetrical processing tanks 4 is used to load diluent.

[0024] Through the coordination of the hydraulic turntable, the transmission box 3, the lifting device and the spraying device, two groups of production can be carried out simultaneously, which improves the production efficiency, and at the same time, the cleaning of the dispersing and stirring device or the grinding device can be carried out synchronously with the production. After the production is completed, the dispersing and stirring device, the grinding device and the processing tank can be automatically and synchronously cleaned, which further improves the cleaning efficiency and avoids the hardening problem caused by untimely cleaning. By utilizing the combined effect of rotary spraying and stirring, the diluent and the dispersing and stirring device, the grinding device and the processing tank are fully and repeatedly collided, thereby improving the cleaning effect.

[0025] The lifting device includes four outer pillars 5, which are symmetrically arranged around the rotation axis of the hydraulic turntable 2. The bottom ends of the four outer pillars 5 are fixedly connected to the rotating end of the hydraulic turntable 2, and the lower parts are fixedly connected to each other through the lower fixed plate 6, and the tops are fixedly connected to each other through the upper fixed plate 7. The opposite surfaces of the four outer pillars 5 are provided with sliding grooves with upper ends opened, and the inner pillars 8 are slidably connected in the sliding grooves. The top ends of the inner pillars 8 are fixedly connected to the bottom wall of the transmission box 3, and the lower parts of the four inner pillars 8 are fixedly connected through connecting plates 9. The bottom wall of the lower fixed plate 6 is fixedly connected to a motor 10, and the output end of the motor 10 is fixedly connected to a screw rod 11. The outer wall of the bottom end of the screw rod 11 penetrates and is rotatably connected to the middle part of the lower fixed plate 6, and the top end of the screw rod 11 is rotatably connected to the middle part of the upper fixed plate 7, and the threaded end of the screw rod 11 penetrates and is threadedly connected to the middle part of the connecting plate 9.

[0026] The motor 10 drives the screw rod 11 to rotate, so that the connecting plate 9 drives the inner support 8 to move up and down along the slide groove in the outer support 5, thereby realizing the lifting and lowering of the transmission box 3. At the same time, by adopting the setting of four outer supports 5 and inner supports 8 arranged in a cross shape corresponding to the transmission box 3, the support stability is improved, and the torque resistance during the rotation process is improved.

[0027] A main pulley 12 is rotatably connected in the middle of the transmission box 3, and slave pulleys 13 are rotatably connected in the four corners of the transmission box 3. The main pulley 12 and the slave pulley 13 are connected by a transmission belt 14. A motor 2 15 is fixedly connected to the center of the upper wall of the transmission box 3, and the output end of the motor 2 15 is fixedly connected to the rotating shaft end of the main pulley 12.

[0028] The main pulley 12 is driven to rotate by the second motor 15, and then the main pulley 12 drives the four slave pulleys 13 to rotate synchronously through the transmission belt 14.

[0029] The dispersing and stirring device includes a stirring rod 16, the top end of the stirring rod 16 is fixedly connected to the rotating shaft end of the pulley 13, the bottom end of the stirring rod 16 is fixedly connected to a stirring head 17, the upper part of the stirring rod 16 is sleeved and rotatably connected to a stabilizing cylinder 18, the top end of the stabilizing cylinder 18 is fixedly connected to the bottom wall of the transmission box 3, and the bottom end is fixedly connected to a cover plate 19, which is sleeved on the outer wall of the stirring rod 16, and the cover plate 19 matches the processing tank 4.

[0030] The grinding device includes a grinding rod 20, the top end of the grinding rod 20 is fixedly connected to the rotating shaft end of the pulley 13, a grinding head 21 is arranged at the bottom of the grinding rod 20, a stabilizing cylinder 22 is sleeved on the outer wall of the grinding rod 20 and rotatably connected, the top end of the stabilizing cylinder 22 is fixedly connected to the bottom wall of the transmission box 3, and a cover plate 23 is sleeved on the outer wall and fixedly connected, and the cover plate 23 matches the processing tank 4.

[0031] It should be noted that the four slave pulleys 13 are arranged opposite to each other in pairs and correspond to the four corners of the transmission box 3. One group of two symmetrical slave pulleys 13 are fixedly connected to the stirring rod 16 for driving the stirring rod 16 to rotate, and the other group of two symmetrical slave pulleys 13 are fixedly connected to the grinding rod 20 for driving the grinding rod 20 to rotate, thereby realizing the synchronous rotation of the stirring rod 16 and the grinding rod 20. The stabilizing cylinder 1 18 and the stabilizing cylinder 2 22 are respectively used to improve the stability of the stirring rod 16 and the grinding rod 20 during the rotation process. At the same time, the cover plate 1 19 and the cover plate 2 23 are respectively fixedly connected to the bottom walls of the four corners of the transmission box 3 through the stabilizing cylinder 1 18 and the stabilizing cylinder 2 22, so that they rise and fall synchronously with the rise and fall of the transmission box 3 and do not rotate. The cover plate 1 19 and the cover plate 2 23 are both matched with the processing tank 4, so that they cover and seal the processing tank 4 to prevent the volatilization of the diluent.

[0032] The spraying device includes a shower tray 1 24, a shower tray 25 and an infusion tube 26, wherein both shower tray 1 24 and shower tray 25 adopt an upper opening structure, and the bottom wall is provided with evenly distributed spray holes, the top end of shower tray 1 24 is embedded in and rotatably connected to the bottom wall of cover plate 19, and the bottom wall of shower tray 1 24 is sleeved and fixedly connected to the outer wall of stirring rod 16, the top end of shower tray 25 is embedded in and fixedly connected to the bottom wall of cover plate 23, and the bottom wall of shower tray 25 is sleeved on the outer wall of stabilizing cylinder 22, one end of infusion tube 26 is connected to the output port of diluent conveyor, and the other end passes through cover plate 19 and cover plate 23, and is connected to the inside of shower tray 1 24 and shower tray 25.

[0033] The spraying device includes two modes, one of which is that the shower plate 24 is rotatably connected to the cover plate 19 and fixedly connected to the stirring rod 16, so that the shower plate 24 rotates synchronously with the rotation of the stirring rod 16, and then the diluent enters the shower plate 24 from the infusion tube 26, and when it is sprayed out from the spray hole, the sprayed liquid column is affected by the centrifugal force generated by the rotation, and a diffusion spray phenomenon occurs, which increases the spray area on the one hand and realizes the flushing of the inner wall of the processing tank 4, and on the other hand, increases the impact force of the liquid column, thereby improving the cleaning strength and efficiency; the other mode is that the shower plate 25 is connected to the cover plate 26, and the diluent enters the shower plate 24 from the infusion tube 26, and then sprays out from the spray hole, and the sprayed liquid column is affected by the centrifugal force generated by the rotation, and the diffusion spray phenomenon occurs, which increases the spray area on the one hand and realizes the flushing of the inner wall of the processing tank 4, and increases the impact force of the liquid column on the other hand, thereby improving the cleaning strength and efficiency; 23 is fixedly connected and is fixedly connected to the stabilizing cylinder 22. In this mode, the diluent is normally sprayed out only from the spray hole of the shower plate 25. This arrangement is adopted because, on the one hand, it is difficult to connect the shower plate 25 with the grinding rod 20 due to the structural limitation of the grinding device itself. On the other hand, the two processing tanks 4 for loading the diluent are mainly used to clean the dispersing stirring device and the grinding device. The probability of the inner wall being adhered is low, and there is no need to flush the inner wall. Even if the inner wall needs to be flushed due to long-term use, the shower plate 1 24 can be rotated and flushed through the hydraulic turntable 2.

[0034] A discharge pipe 27 is arranged on the bottom wall of the processing tank 4, wherein the discharge pipe 27 of the processing tank 4 for loading the mixed raw material is connected with the storage tank and the diluent recovery device at the same time, and valves for opening and closing are respectively arranged thereon, and the discharge pipe 27 of the processing tank 4 for loading the diluent is connected with the diluent recovery device, and a valve is arranged on the pipeline.

[0035] The two processing tanks 4 for loading the mixed raw materials are connected to the storage tank and the diluent recovery device at the same time, so that the amino paint coating after mixing enters the storage tank through the discharge pipe 27 to facilitate the subsequent packaging operation, and the diluent after cleaning the processing tank 4 enters the diluent recovery device for recycling again. When the diluent in the processing tank 4 for loading the diluent needs to be replaced, the diluent therein is first discharged into the diluent recovery device, and then the diluent is injected through the spraying device.

[0036] The feeding device includes a feeding hopper 28, and telescopic rods 29 are rotatably connected to both sides of the outer wall in the middle of the feeding hopper 28, one end of the inner rod of the telescopic rod 29 is fixedly connected to a bracket 30, and a spring 31 is sleeved on the outer wall of the inner rod of the telescopic rod 29, one end of the spring 31 is fixedly connected to the side wall of the bracket 30, and the other end is fixedly connected to the end face of the outer rod of the telescopic rod 29, the outer wall of the bracket 30 and the upper part of the feeding hopper 28 are fixedly connected by a spring 2 32, and the bottom of the bracket 30 is fixedly connected to the outer wall of the processing tank 4.

[0037] The feeding hopper 28 is used to provide convenience for the feeding process. When feeding is required, the lifting device drives the transmission box 3 to rise, and the feeding hopper 28 is freed from the restriction of the cover plate 19 or the cover plate 23, and is pushed to the top of the opening on the processing tank 4 under the action of the spring 1 31. At the same time, under the action of the spring 2 32, the discharge port of the feeding hopper 28 is tilted toward the center of the processing tank 4, so that the discharge port of the feeding hopper 28 is completely within the range of the opening on the processing tank 4 to facilitate the addition of raw materials; when the feeding is completed, the lifting device drives the transmission box 3 to descend, and the cover plate 19 or the cover plate 23 contacts the tilted feeding hopper 28 during the descending process, and pushes the feeding hopper 28 to move outward and align, so that the feeding hopper 28 moves out of the range of the opening on the processing tank 4.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
