Description

Technical Field

[0001] The utility model relates to the technical field of coating production, in particular to a coating heating device. Background Art

[0002] When producing water-based paint, a heater is needed to heat the paint. For example, Chinese authorized patent CN220206314 U discloses a water-based paint heater with uniform heating. The heating cylinder rotates in a support sleeve, and the stirring of the internal material by a stirring paddle is combined with the high temperature generated by the heating resistance wire evenly laid in the cavity of the heating cylinder, so that the material can be heated evenly.

[0003] This device still has some shortcomings that need further improvement. First, its heat source is located inside the shell of the heating cylinder. Therefore, the paint on the outside of the cylinder is obviously exposed to different heat than the paint on the inside. Moreover, when the cylinder diameter is large, the paint is heated only by heat radiation from the outside to the inside, which takes a long time. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, the utility model provides a technical solution: a paint heating device, including a base 1 and a bearing seat 2 rotatably installed on the top of the base 1, a cylinder 3 is arranged on the base 1, the cylinder 3 can drive the bearing seat 2 to rotate on the base 1, and the cylinder 3 can drive the heating tube 5 to tilt for easy unloading.

[0026] like Figure 1 , 4 As shown, a support frame 4 is provided on the top of the bearing seat 2, and a dark groove 41 is opened on the inner side of the support frame 4. A plurality of groups of rotatable support rollers 42 are installed in the dark groove 41, and the support rollers 42 are in contact with the outer wall of the heating tube 5. In the traditional contact mode, the heating tube 5 and the support mechanism directly belong to the sliding static friction mode, and the friction force is relatively large, and the load requirement for the first motor 6 is large. Here, a rotatable support roller 42 and a similarly rotatable heating tube 5 are used, and the friction coefficient between the two is small, and the load is small. A rotatable heating tube 5 is provided on the support frame 4, and a gear ring 8 is provided on the outer wall of the heating tube 5. A first motor 6 is also provided on the bearing seat 2, and a rotatable driving gear 7 is installed on the output end of the first motor 6, and the driving gear 7 is meshed with the gear ring 8.

[0027] like Figure 1 As shown, a feed port 9 and a discharge port 10 are respectively provided at the top and the bottom of the heating cylinder 5 .

[0028] like Figure 2 As shown, a heating chamber 51 is provided in the heating tube 5 (the heating chamber 51 is not connected with the feed port 9 and the discharge port 10 ), and a heating wire 52 is provided in the heating chamber 51 .

[0029] like Figure 2 As shown, a second motor 11 is provided on one side of the heating tube 5, and a hollow stirring shaft 12 is installed at the output end of the second motor 11. An air outlet 121 is provided on the stirring blade of the stirring shaft 12. The air outlet 121 has a small aperture and a high hot air flow pressure, so the paint will not enter the air outlet 121 and cause blockage. A support plate 13 is also provided on the top of the supporting seat 2, and one end of the stirring shaft 12 passes through the heating tube 5 and extends into the support plate 13.

[0030] like Figure 3As shown, a heating pipe 14 is installed on one side of the support plate 13, and a switch valve 15 is provided on the heating pipe 14. The air outlet of the heating pipe 14 extends into the support plate 13 and is connected to the air inlet of the stirring shaft 12. A sealing ring 18 is provided at the connection between the heating pipe 14 and the support plate 13.

[0031] like Figure 3 As shown, the support plate 13 has a built-in drying sleeve 16 , the two ends of which are respectively connected to the heating pipe 14 and the stirring shaft 12 , the rotation of the stirring shaft 12 will not interfere with the drying sleeve 16 , and a water-absorbing sponge 17 is arranged in the drying sleeve 16 .

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field.

[0033] When in use, the paint enters the heating tube 5 through the feed port 9, and the first motor 6 and the second motor 11 are started synchronously. The first motor 6 drives the driving gear 7 to rotate, and then drives the heating tube 5 to start rotating. The second motor 11 drives the stirring shaft 12 to rotate, thereby stirring the paint and making it evenly heated. It should be noted that the direction of the heating tube 5 is preferably opposite to that of the stirring shaft 12, so that the turning rate of the paint can be accelerated.

[0034] Heat is radiated from the outside to the inside through the heating wire 52 in the heating chamber 51, and the switch valve 15 is opened to introduce external hot air. The hot air enters the stirring shaft 12 after being dried by the water-absorbing sponge 17, and finally is ejected through the air outlet holes 121 on the numerous stirring blades at the end to contact the coating, realizing heat radiation from the inside to the outside, thereby improving the heating efficiency.

[0035] To summarize, the paint heating device improves the stirring shaft, adopts a hollow structure, and then connects an external heat source at the axis of the stirring shaft. The heat source is introduced into the stirring shaft and released through the stirring blades on the stirring shaft to directly contact the paint. Since the stirring shaft is located in the center of the heating cylinder and is combined with the heat source on the outside, an internal and external dual heating mode is formed. In this way, not only the paint is heated more evenly, but also the heating time is shortened and the efficiency is improved.

[0036] It should be noted that the electrical components appearing in this article are all connected to the external main controller and 220V or 380V mains electricity, and the main controller can be a conventional known device for controlling computers, etc. Its control principle, internal structure and control switch mode are all conventional means of the prior art, which are directly quoted here without further elaboration. In this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
