[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0020] The following describes a device for testing the viscosity of hot-melt road marking paint according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 3 As shown, the hot-melt road marking paint viscosity testing device of the embodiment of the utility model may include a housing 1, a driving mechanism 2, a surrounding mechanism 3, a feeding port 4, a receiving mechanism 5, two stirring mechanisms 6 and a plurality of viscosity meters 7.

[0022] Among them, the driving mechanism 2 is arranged on the outer shell 1, the top of the outer shell 1 is provided with two slots 11, the surrounding mechanism 3 is installed on the top of the outer shell 1, the feeding port 4 is arranged on the surrounding mechanism 3, the bottom of the outer shell 1 is upwardly concave, and discharge ports 12 are provided on both sides of the outer shell 1.

[0023] In the embodiment of the utility model, the bottom of the shell 1 is concave so that the paint can be located on both sides of the shell 1, and at the same time, it is convenient to collect the paint after collecting it.

[0024] The receiving mechanism 5 is installed inside the housing 1 , and the receiving mechanism 5 is connected to the driving mechanism 2 .

[0025] It should be noted that the receiving mechanism 5 can cooperate with the driving mechanism 2 to drive the stirring mechanism 6 to rotate, thereby stirring the paint inside the housing 1.

[0026] The two stirring mechanisms 6 are installed on the receiving mechanism 5 . The stirring mechanism 6 may include an arc-shaped shell 61 , an inner groove 611 , a plurality of heating rods 62 and a blocking plate 63 .

[0027] A plurality of heating rods 62 are installed on the surface of the arc-shaped shell 61 .

[0028] It can be understood that by heating the coating material with the heating rod 62 while the coating material is rotating, the coating material can be heated more fully and evenly.

[0029] An inner groove 611 is formed on the surface of the arc-shaped shell 61 , a blocking plate 63 is installed on a side of the inner groove 611 close to the receiving mechanism 5 , and a viscosity meter 7 is installed on the stirring mechanism 6 .

[0030] It should be noted that the groove is used to collect the paint at the top of the arc-shaped shell 61. When part of the paint remains on the top of the stirring mechanism 6, the paint can slide from the surface of the arc-shaped shell 61 to the inner groove 611, and then flow into the bottom of the outer shell 1 on the opposite side.

[0031] Specifically, when the viscosity of the paint needs to be tested, the relevant personnel put the paint into the accommodating cavity 33 from the feeding port 4, and the paint flows from the slot 11 into the inside of the shell 1 on both sides through the first inclined plates 31 on both sides. The rotating motor 21 is controlled to punch, and the rotating motor 21 drives the first gear 22 to rotate. During the rotation of the first gear 22, the transmission chain 23 is driven to rotate. Based on the transmission relationship between the transmission chain 23 and the second gear 53, the second gear 53 will also rotate. When the second gear 53 rotates, the second gear 53 will drive the connecting rod 52 to rotate, and then drive the stirring mechanism 6 to rotate to heat and stir the marking paint, so that the paint is heated and mixed more evenly.

[0032] After the stirring is completed, the viscosity meters 7 on both sides can test the viscosity of the marking paint respectively. The test results obtained by multi-point testing can be more accurate. When the test is completed, the paint can be discharged from the discharge port 12.

[0033] Therefore, by mixing the coating while heating it, the viscosity measurement deviation caused by local overheating or insufficient melting is avoided, the accuracy of the test result is improved, and it is beneficial to the performance evaluation of the coating.

[0034] In the embodiment of the present utility model, a gate valve may be provided on the surface of the discharge port 12 to control the discharge of the coating material.

[0035] In one embodiment of the present invention, Figure 2 As shown, the driving mechanism 2 may include a rotary motor 21 , a first gear 22 and a transmission chain 23 .

[0036] The rotating motor 21 is mounted on the housing 1 , the center of the first gear 22 is connected to the output shaft of the rotating motor 21 , and the transmission chain 23 is meshed with the first gear 22 .

[0037] It can be understood that the meshing relationship between the first gear 22 and the transmission chain 23 can drive the second gear 53 to rotate.

[0038] In one embodiment of the present invention, Figure 1 As shown, the enclosing mechanism 3 may include a first inclined plate 31 and a surrounding plate 32.

[0039] The two first inclined plates 31 are installed on the inner sides of the two slots 11 and are located at the top of the driving mechanism 2 . The surrounding plate 32 is installed on the top of the housing 1 . After installation, the first inclined plates 31 and the surrounding plate 32 enclose a receiving cavity 33 .

[0040] It should be noted that when the paint is fed into the feed port 4, the paint can enter the grooves 11 on both sides from the first inclined plates 31 on both sides, and slide from the inclined plates on both sides to the inside of the housing 1. The heating speed of the paint can be increased, and the measurement efficiency can be improved.

[0041] In one embodiment of the present invention, Figure 1 As shown, the receiving mechanism 5 may include a bearing seat 51 , a connecting rod 52 and a second gear 53 .

[0042] Among them, the bearing seat 51 is symmetrically installed on the inner wall of the shell 1, the connecting rod 52 is installed between the two bearing seats 51, the second gear 53 is installed in the middle of the connecting rod 52 and is on the same vertical line as the first gear 22, and the second gear 53 is meshed and connected with the transmission chain 23.

[0043] It should be noted that the meshing relationship between the first gear 22 and the second gear 53 described in this embodiment and the transmission chain 23 can ensure that the second gear 53 drives the connecting rod 52 to rotate, and the bearing seats 51 arranged on both sides can maintain the rotation of the connecting rod 52.

[0044] In one embodiment of the present invention, Figure 1 As shown, the shapes of the bottom of the housing 1 and the two stirring mechanisms 6 match each other.

[0045] It should be noted that the shape of the bottom of the housing 1 can ensure the normal rotation of the stirring mechanism 6, and at the same time, can keep the paint inside the housing 1 and can be easily discharged from the downwardly inclined housing 1 after the test is completed.

[0046] In summary, the hot-melt road marking paint viscosity testing device of the embodiment of the utility model avoids viscosity measurement deviation caused by local overheating or insufficient melting by mixing the paint when heating the paint, improves the accuracy of the test results, and is conducive to the performance evaluation of the paint.
