TECHNICAL FIELD
[0001] The utility model relates to the technical field of paint production, especially relates to a paint heater for paint production line. BACKGROUND
[0002] When heating the paint, a paint heater for paint production line is often used, which is a device specially designed to improve the temperature control accuracy in the paint production process. By uniformly and efficiently heating the paint, it ensures that the paint is mixed, reacted and solidified at an appropriate temperature, thereby significantly improving production efficiency, ensuring the stability of product quality, and reducing production defects caused by improper temperature. It is an indispensable key equipment for optimizing the paint production process.
[0003] In the paint production line, the paint is usually input into the heater, which is uniformly heated by electric heating, steam heating or circulating hot air, etc. to reach the appropriate construction temperature. Then the heated paint is transported to the next production link, such as spraying or mixing process. The temperature control of the heater and the flow rate of the paint need to be accurately adjusted throughout the process to ensure product quality and production efficiency.
[0004] In the prior art, some paint heater devices for paint production line have many shortcomings. From the aspect of stirring, the existing device has a simple stirring structure design, and the shape and layout of the stirring paddle are unreasonable, so that the paint cannot be fully and uniformly stirred during the stirring process. Some paint is in the corner of the device for a long time and is not effectively stirred, resulting in uneven distribution of paint components. For example, in some paint production with high requirements for pigment dispersity, pigment agglomeration is serious due to insufficient stirring, which affects the color uniformity and stability of the paint. As for heating, the heating method in the prior art is inefficient, most of which uses a single heating element, and the contact area between the heating element and the paint is limited, so the heat transfer is slow. This not only leads to long heating time and reduces production efficiency, but also easily causes local overheating or insufficient heating of the paint. Local overheating can cause decomposition and deterioration of some components in the paint, affecting the quality of the paint. Insufficient heating cannot make the paint achieve the best performance, such as poor flowability of the paint, which makes it difficult to evenly apply during construction. Therefore, a paint heater for paint production line is proposed to solve the above problems. SUMMARY

[0037] The driving assembly comprises a motor 4, a device for providing stirring power, and a transmission device for transmitting power to a rotating shaft 5, the motor 4 is fixedly connected outside the motor 4, the rotating shaft 5 is rotatably connected inside the motor 4, the cleaning mechanism comprises a fixed block 15, which is a basic part of the cleaning mechanism, and is fixedly connected to one side of the outer side of the main stirring paddle 6 through a bolt, so as to ensure that the fixed block 15 will not be loose during stirring, and the outer side of the fixed block 15 is fixedly connected with a connecting rod 16, which connects the fixed block 15 and a follower rod 17, so that the follower rod 17 can move relative to the fixed block 15;
[0038] The outer side of the connecting rod 16 is rotatably connected with the follower rod 17, which can freely swing with the rotation of the main stirring paddle 6 and move with the movement of the connecting rod 16, so as to drive the scraper 18 to clean the inside of the heat-conducting barrel 2, the outer side of the follower rod 17 is fixedly connected with the scraper 18, which can be tightly attached to the inner surface of the heat-conducting barrel 2, so as to timely remove the paint attached to the barrel wall during stirring, ensure the heat-conducting effect and the cleanliness of the device, the scraper 18 is connected with the follower rod 17 through a rotating shaft 5, which can automatically adjust the angle during work to achieve the best cleaning effect, and is used for scraping the residual paint in the heat-conducting barrel 2, the outer side of the fixed block 15 is fixedly connected to the outer side of the main stirring paddle 6, and the outer side of the scraper 18 is rotatably connected to the inside of the heat-conducting barrel 2.
[0039] Referring to Figures 2 to 3 The bottom of the rotating shaft 5 is rotatably connected with a driving bevel gear 7, which converts the high-speed low-torque power input by the rotating shaft 5 into low-speed high-torque power output through meshing transmission with a driven bevel gear 10, so as to meet the needs of the device under different working conditions, and the bottom of the heat-insulating cylinder 1 is fixedly connected with two supports 8 on the left and right sides, so as to ensure that the driving rod 9 will not shake or displace during work, and to provide convenience for assembly and debugging of the whole device.

In the transmission process, the belt 12 transmits power through the friction between the belt 12 and the belt pulley 11, so it is necessary to ensure that the belt 12 and the belt pulley 11 have sufficient friction and tension. At the same time, the belt 12 also needs to have certain elasticity and buffering performance to reduce impact and vibration in the transmission process.
[0042] With reference to Figures 3 to 4 The inner part of the two belt pulleys 11 is rotatably connected with two driven rotating shafts 13 on the left and right sides, which is an intermediate link for power transmission.

At the same time, the driven rotating shaft 13 also supports and positions the longitudinal stirring mechanism 14, ensuring that the longitudinal stirring mechanism 14 maintains a stable posture during stirring.
[0043] The outer part of the two longitudinal stirring mechanisms 14 is fixedly connected to the outer part of the driven rotating shaft 13 on the upper and lower sides. The top side of the heat preservation cylinder 1 is fixedly connected with a heating box 19, which provides heat for the paint in the heat preservation cylinder 1, so that it can be kept within a certain temperature range to meet the process requirements of the paint. In the production process of the paint, some paints need to be stirred, reacted, etc. under specific temperature conditions. The heating box 19 can provide stable heat source to ensure that the quality and performance of the paint are not affected.
[0044] The outer part of the heating box 19 is fixedly connected with an oil return pipe 20, which recycles and retransmits the used liquid to realize the recycling of the liquid.

At the same time, it can also play the roles of heat dissipation, lubrication, etc. The outer part of the oil return pipe 20 is fixedly connected to the inner part of the heat preservation cylinder 1.
[0046] The outer side of the heat preservation cylinder 1 is fixedly connected with a paint outlet 22, and the paint which is uniformly stirred and meets the quality requirements is discharged from the heat preservation cylinder 1 to be processed or used subsequently.

The bottom space area of the heat preservation cylinder 1 is fixedly connected with a supporting leg 23. During the installation and use of the stirring device, the supporting leg 23 bears the weight of the heat preservation cylinder 1 and the materials and equipment in the heat preservation cylinder 1.
[0047] Working principle: the paint enters the heat conducting barrel 2 through the paint inlet 3, the motor 4 is started, the rotating shaft 5 is driven to rotate, the main stirring paddle 6 is driven to stir the paint, at the same time, the driving bevel gear 7 at the bottom of the rotating shaft 5 meshes with the driven bevel gear 10 to drive the driving rotating rod 9 to rotate, the driving rotating rod 9 transmits power to the driven rotating rod 13 through the belt pulley one 11 and the belt one 12 to make the longitudinal stirring mechanism 14 rotate to further stir the paint. In the stirring process, the heating box 19 provides heat for the paint in the heat preservation cylinder 1. The uniformly stirred and heated paint is discharged through the paint outlet 22. The used liquid is recycled through the oil return pipe 20 under the action of the circulating pump 21.
[0048] When the main stirring paddle 6 rotates, the fixed block 15 is driven to rotate to ensure that it does not loosen during stirring. One end of the connecting rod 16 is fixedly connected with the fixed block 15, and the other end is rotatably connected with the driven rod 17 which can freely swing with the rotation of the main stirring paddle. The scraper 18 is fixedly connected to the outer side of the driven rod 17 and can tightly fit the inner surface of the heat conducting barrel 2. The scraper 18 can timely remove the paint attached to the barrel wall during stirring to ensure the heat conduction effect and the cleanliness of the equipment. The scraper 18 is connected with the driven rod 17 through a rotating shaft 5 and can automatically adjust the angle during work. The scraper 18 removes the residual paint in the heat conducting barrel 2 to achieve the best cleaning effect.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features.
