[0034] Embodiment 1

[0035] This embodiment provides a constant-temperature production reaction device for mildew-proof leather auxiliaries. As Figure 1 shown, it includes a mixing tank 1. A shock-absorbing base 2 is fixedly installed at the bottom of the mixing tank 1. A feeding port 4 is fixedly installed at the top of the mixing tank 1. A motor 3 is fixedly installed at the center of the top of the mixing tank 1. A sandwich layer is provided on the inner wall of the mixing tank 1, and a heating pipe 5 is fixedly installed in the sandwich layer. The heating pipe 5 heats the raw materials inside the mixing tank 1 to enable the raw materials to be produced in a constant-temperature environment. A heat conduction plate is fixedly installed between the mixing tank 1 and the heating pipe 5 to make the heating more uniform. A temperature control device is fixedly installed on the inner wall of the mixing tank 1. The temperature control device is electrically connected to the heating pipe 5 through a controller to detect the temperature inside the mixing tank 1 and adjust the heating temperature of the heating pipe 5 in real time to achieve the effect of constant temperature. The temperature control device is a prior art, so it will not be described in detail here.

[0036] As Figure 2 andFigure 3 As shown, an anti-curing component 6 is provided inside the mixing tank 1. The anti-curing component 6 includes a stirring shaft 61, stirring blades 62, a differential component, a rotating cylinder 63, and a diversion scraping block 68. The stirring blades 62 are fixedly installed on the rod body of the stirring shaft 61. The stirring shaft 61 is rotationally connected to the rotating cylinder 63 through the differential component. The diversion scraping block 68 is fixedly installed on the arc surface of the rotating cylinder 63.

[0037] As Figure 4 shown, the diversion scraping block 68 is in the shape of a frustum of a square pyramid. The side of the diversion scraping block 68 facing the inner wall of the mixing tank 1 has an arc surface structure. The arc radian of the arc surface of the rotating cylinder 63 is the same as that of the inner wall arc surface of the mixing tank 1. This increases the contact area between the diversion scraping block 68 and the mixing tank 1, and at the same time makes the scraping effect better.

[0038] The rotating cylinder 63 drives the diversion scraping block 68 to rotate through the differential component. The diversion scraping block 68 scrapes off the raw materials adhering to the inner wall of the mixing tank 1. At the same time, the raw materials move along the inclined surface of the diversion scraping block 68 towards the center of the mixing tank 1 for mixing. A plurality of diversion scraping blocks 68 are provided and are evenly distributed at equal angles along the inner wall of the mixing tank 1. A scraping strip 69 is fixedly installed on the top of each diversion scraping block 68. The scraping strip 69 is a long strip formed by thermoplastic polyurethane elastomer, which has the characteristic of high temperature resistance and prevents melting during the production of leather auxiliaries. The scraping strip 69 contacts the inner wall of the mixing tank 1, and the scraping strip 69 scrapes off the adhering raw materials on the inner wall of the mixing tank 1.

[0039] As Figure 2 shown, an annular groove is provided on the inner wall of the mixing tank 1. A positioning ring 8 is rotatably connected in the annular groove. The tops of a plurality of scraping strips 69 are fixedly connected to the positioning ring 8. The positioning ring 8 fixes the positions of the plurality of scraping strips 69, so that the scraping strips 69 are always in a vertical state. A guiding groove is provided on the diversion scraping block 68, and the guiding groove diverts the raw materials shoveled up by the diversion scraping block 68.

[0040] When cleaning the mixing tank 1, the diversion scraping block 68 and the scraping strip 69 scrape off the anti-mildew leather auxiliaries remaining on the inner wall of the mixing tank 1, avoiding the influence of the remaining anti-mildew leather auxiliaries on the subsequent production of anti-mildew leather auxiliaries.

[0041] A plurality of groups of stirring blades 62 are provided. The plurality of groups of stirring blades 62 are evenly distributed at equal intervals along the stirring shaft 61. A plurality of stirring blades 62 are provided in each group, and the plurality of stirring blades 62 are evenly distributed at equal angles around the rod body of the stirring shaft 61. The motor 3 drives the stirring shaft 61 to rotate, so that the stirring blades 62 rotate. The design of the plurality of groups of stirring blades 62 enables the raw materials at different heights inside the mixing tank 1 to be mixed, improving the mixing efficiency.

[0042] In this embodiment, while the stirring shaft 61 and the stirring blades 62 stir and mix the raw materials, the stirring shaft 61 drives the rotating cylinder 63 to rotate, so that the diversion scraping block 68 and the scraping strip 69 rotate to scrape off the viscous raw materials adhering to the inner wall of the mixing tank 1. At the same time, the diversion scraping block 68 diverts the adhering raw materials to move them towards the center of the mixing tank 1, preventing the raw materials from adhering to the inner wall of the mixing tank 1 for a long time and being heated and cured by the heating pipe 5, and preventing the cured raw materials from causing poor heat transfer and affecting the constant temperature environment in the mixing tank 1.

[0043] Embodiment 2

[0044] Based on Embodiment 1, this embodiment proposes a constant-temperature production reaction device for anti-mildew leather auxiliaries. As Figure 1 shown, a water spraying port is provided on the inner wall of the top of the mixing tank 1. A water pipe is inserted through the water spraying port to spray water so as to clean the mixing tank 1.

[0045] As Figure 3 shown, the differential assembly includes a convex block 64, a first gear 65, a second gear 66 and a ring gear tooth 67. A convex block 64 is fixedly installed at the bottom of the stirring shaft 61. A first gear 65 is fixedly installed at the bottom of the convex block 64. A ring gear tooth 67 is provided at the top of the rotating cylinder 63. The center of the bottom of the second gear 66 is rotationally connected to the rotating cylinder 63 through a rotating shaft. The first gear 65 is meshed with the ring gear tooth 67 through the second gear 66.

[0046] Through the gear ratio of the first gear 65, the second gear 66 and the ring gear tooth 67, the rotation speed of the rotating cylinder 63 is reduced. In order to make the effect of the diversion scraping block 68 and the scraping strip 69 scraping off the raw materials adhering to the inner wall of the mixing tank 1 better, the friction between the diversion scraping block 68, the scraping strip 69 and the inner wall of the mixing tank 1 is large. Therefore, if the diversion scraping block 68 and the scraping strip 69 rotate rapidly, it will cause wear of the diversion scraping block 68 and the scraping strip 69 and reduce their scraping effect. Therefore, it is necessary to reduce the speed to protect the diversion scraping block 68 and the scraping strip 69.

[0047] As Figure 3 shown, a groove is provided at the top of the rotating cylinder 63. The convex block 64 is inserted into the groove at the top of the rotating cylinder 63 to improve the sealing performance between the stirring shaft 61 and the rotating cylinder 63. The first gear 65, the second gear 66 and the ring gear tooth 67 are used in cooperation, and the rotating directions of the stirring shaft 61 and the scraping strip 69 are opposite, further improving the stirring effect.

[0048] As Figure 5As shown in the figure, a transposition assembly 7 is provided between the rotary drum 63 and the diversion scraping block 68. The transposition assembly 7 includes a transposition plate 71, a guide rod 72, a guide insertion cylinder 73, a first strong magnet 74, and a second strong magnet 75. The bottom of the transposition plate 71 is slidably connected to the inner wall of the bottom of the mixing tank 1. The side of the transposition plate 71 is fixedly connected to the guide rod 72. The guide rod 72 slides inside the guide insertion cylinder 73. The end of the guide insertion cylinder 73 is fixedly installed on the rotary drum 63. The second strong magnet 75 is fixedly installed on the convex block 64. The end of the guide rod 72 is fixedly installed with the first strong magnet 74.

[0049] Through the gear ratios of the first gear 65, the second gear 66, and the ring gear teeth 67, the rotational speeds between the stirring shaft 61 and the rotary drum 63 are different. One end of the second strong magnet 75 facing the first strong magnet 74 continuously changes stimuli as the stirring shaft 61 rotates. One end of the first strong magnet 74 facing the second strong magnet 75 is an S pole. The first strong magnet 74 first moves towards the second strong magnet 75. Subsequently, as the magnetic pole of the second strong magnet 75 rotating towards the first strong magnet 74 changes from an N pole to an S pole, at this time, the first strong magnet 74 is repelled and moves away from the second strong magnet 75. While the first strong magnet 74 moves, it drives the guide rod 72 to move. The guide rod 72 drives the transposition plate 71 to move. The transposition plate 71 reciprocates to drive the raw materials near the side wall of the mixing tank 1 to the center of the mixing tank 1, and pushes the raw materials at the center to the side wall position of the mixing tank 1, making the heating more uniform.

[0050] In this embodiment, through the gear ratios of the first gear 65, the second gear 66, and the ring gear teeth 67, the rotational speed of the diversion scraping block 68 is slower than that of the stirring shaft 61 to avoid the wear of the diversion scraping block 68 and the scraping strip 69 and the generation of heat caused by the large friction between the diversion scraping block 68, the scraping strip 69 and the inner wall of the mixing tank 1 and the fast rotational speeds of the diversion scraping block 68 and the scraping strip 69.

[0051] The above specific embodiments are merely several alternative embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
