[0028] As described in the background technology, in existing hot melt adhesive material particle mixing devices, material particles often adhere to the inner wall of the device during the mixing process. This is mainly due to the special properties of hot melt adhesive material particles, such as viscosity and fluidity, which make them easy to contact and adhere to the inner wall of the device when stirred or rotated. The attached material particles will hinder the flow of materials during the mixing process, resulting in uneven mixing, thereby affecting the quality of the hot melt adhesive product.

[0029] In order to solve this technical problem, the utility model provides a hot melt adhesive material particle mixing device, which is used for mixing hot melt adhesive material particles.

[0030] Specifically, please refer to Figure 1 、 Figure 3 and Figure 4 The hot melt adhesive material particle mixing device specifically includes:

[0031] Mixing tank 1, a cover plate 2 is installed on the top of the mixing tank 1, and two support rods 201 are fixedly installed on the top of the cover plate 2, a support base 202 is fixedly connected between the two support rods 201, the middle part of the support base 202 is connected to a first transmission tube 203 through a bearing, a rotating shaft 204 is inserted in the first transmission tube 203, a driving member 21 is arranged between the rotating shaft 204 and the support base 202, the bottom end of the rotating shaft 204 extends into the mixing tank 1 and is fixedly connected to a plurality of stirring blades 209, the bottom end of the first transmission tube 203 is fixedly connected to a second transmission tube 210, both sides of the second transmission tube 210 are fixedly connected to a support frame 211, two scrapers 212 are fixedly connected between the two support frames 211, the scraper 212 contacts the inner wall of the mixing tank 1, and the scraper 212 is arranged at an angle, and the scraper 212 is used to scrape off the material on the inner wall of the mixing tank 1.

[0032] The hot melt adhesive material particle mixing device provided by the utility model has a scraper 212 set up in the present application. The scraper 212 can effectively scrape off the material particles attached to the inner wall of the mixing tank 1 during the rotation process, ensuring that the material can be evenly distributed during the mixing process, thereby improving the uniformity of the mixing, and preventing the material from adhering to the inner wall of the mixing tank 1 during the mixing process, thereby reducing material waste and reducing production costs.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0036] Example 1, please refer to Figure 1 、 Figure 3 and Figure 4, a hot melt adhesive material particle mixing device, including a mixing tank 1, a cover plate 2 is installed on the top of the mixing tank 1, and two support rods 201 are fixedly installed on the top of the cover plate 2, a support base 202 is fixedly connected between the two support rods 201, the middle part of the support base 202 is connected to a first transmission tube 203 through a bearing, a rotating shaft 204 is inserted in the first transmission tube 203, a driving member 21 is provided between the rotating shaft 204 and the support base 202, the bottom end of the rotating shaft 204 extends into the mixing tank 1 and is fixedly connected to a plurality of stirring blades 209, the bottom end of the first transmission tube 203 is fixedly connected to a second transmission tube 210, and the second transmission tube 211 is fixedly connected to the mixing tank 1. Both sides of the moving tube 210 are fixedly connected to support frames 211, and two scrapers 212 are fixedly connected between the two support frames 211. The scrapers 212 are in contact with the inner wall of the mixing tank 1, and the scrapers 212 are arranged at an angle, and the scrapers 212 are used to scrape off the material on the inner wall of the mixing tank 1. Through the arrangement of the scrapers 212, the scrapers 212 can effectively scrape off the material particles attached to the inner wall of the mixing tank 1 during the rotation process, ensuring that the material can be evenly distributed during the mixing process, thereby improving the uniformity of the mixing, and preventing the material from adhering to the inner wall of the mixing tank 1 during the mixing process, thereby reducing material waste and reducing production costs.

[0037] Further, such as Figure 3 As shown, the outer surface of the rotating shaft 204 passes through the second transmission tube 210, and bearings are provided at the connection between the outer surface of the rotating shaft 204 and the first transmission tube 203 and the second transmission tube 210. The setting of the bearings enables the support seat 202 to support the first transmission tube 203, and the first transmission tube 203 to support the rotating shaft 204.

[0038] Further, such as Figure 1 and Figure 3 As shown, the driving member 21 includes a first bevel gear 205 fixedly mounted on the top of the rotating shaft 204 and a second bevel gear 206 fixedly mounted on the outer surface of the first transmission tube 203. A third bevel gear 207 is meshed between the second bevel gear 206 and the first bevel gear 205, and a motor 208 is installed between the third bevel gear 207 and the two support rods 201. The motor 208 can make the rotating shaft 204 and the first transmission tube 203 rotate in opposite directions through the third bevel gear 207, the first bevel gear 205 and the second bevel gear 206. Due to the plate-shaped arrangement of the scraper 212, it can not only scrape off the material on the inner wall of the mixing tank 1, but also play a stirring role during the rotation of the scraper 212. Therefore, the stirring direction of the scraper 212 is opposite to that of the stirring blade 209, so that the material in the mixing tank 1 can be stirred in multiple directions to improve the uniformity of stirring.

[0039] Further, such as Figure 1 、 Figure 3 and Figure 5As shown, the cover plate 2 is installed on the top of the mixing tank 1 by fixing bolts. After unscrewing the fixing bolts, the cover plate 2 can be removed from the top of the mixing tank 1, which is convenient for cleaning of various components. The top of the mixing tank 1 is provided with two protective plates 3 located on both sides of the cover plate 2. A number of hand-tightening bolts 302 are provided between the protective plates 3 and the mixing tank 1. The hand-tightening bolts 302 can fix the position of the protective plates 3. After unscrewing the hand-tightening bolts 302, the protective plates 3 can be removed from the top of the mixing tank 1, which is convenient for cleaning the inside of the mixing tank 1.

[0040] Example 2, the hot melt adhesive material particle mixing device provided in Example 1 is further optimized, specifically, as Figure 1 、 Figure 3 and Figure 5 As shown, a socket 301 is provided on the protective plate 3, and a filter basket 303 is inserted into the socket 301. Both sides of the top of the filter basket 303 are fixedly connected with baffles 304. The baffles 304 can limit the filter basket 303. The filter basket 303 can move up and down in the socket 301. The filter basket 303 can screen the material particles and reduce the situation where large particles of material fall into the mixing tank 1 and affect the uniformity of the material after mixing.

[0041] Further, such as Figure 5 As shown, a handle 305 is fixedly connected between the filter basket 303 and the top of the blocking bar 304 , and the handle 305 is used to assist in lifting the filter basket 303 .

[0042] Further, such as Figure 5 As shown, a guide wheel 213 is fixedly connected to the top of the support frame 211. The position of the guide wheel 213 corresponds to the position of the filter basket 303, and arc-shaped slopes are provided on both sides of the bottom of the filter basket 303. The scraper 212 drives the guide wheel 213 to rotate during rotation. When the guide wheel 213 contacts the bottom of the filter basket 303, it can push the filter basket 303 to rise. After the guide wheel 213 is separated from the filter basket 303, the filter basket 303 is reset under the action of gravity, so that the filter basket 303 can vibrate up and down during the stirring process, which is convenient for screening materials. Since the materials fall into the mixing tank 1 after screening, the materials are not piled in the mixing tank 1 at one time during this process, but are equivalent to being dispersed and added, so that the mixing of the materials is more uniform.

[0043] Example 3, the hot melt adhesive material particle mixing device provided in Example 1 or 2 is further optimized, specifically, as Figure 1 and Figure 2 As shown, a plurality of support columns 103 are fixedly connected to the outer surface of the mixing tank 1 , and the support columns 103 are used to support the mixing tank 1 .

[0044] Further, such as Figure 1 and Figure 2As shown, a reinforcement ring 104 is fixedly connected between the support columns 103 , and the reinforcement ring 104 is used to reinforce the support columns 103 .

[0045] Further, such as Figure 2 As shown, a discharge port 101 is provided at the bottom of the mixing tank 1, and a sealing plug 102 is threadedly connected to the inner wall of the discharge port 101. After the mixing is completed, the sealing plug 102 is rotated to separate the sealing plug 102 from the discharge port 101 so that the material in the mixing tank 1 can be discharged from the discharge port 101.

[0046] The use process of the hot melt adhesive material particle mixing device provided by the utility model is as follows:

[0047] The material particles are poured into the baffle 304 and the motor 208 is started. The motor 208 makes the rotating shaft 204 and the first transmission tube 203 rotate in opposite directions through the third bevel gear 207, the first bevel gear 205 and the second bevel gear 206. The rotating shaft 204 drives the stirring blade 209 to rotate, and the first transmission tube 203 drives the scraper 212 to rotate. During the rotation of the scraper 212, the material on the inner wall of the mixing tank 1 is scraped off, and the scraper 212 also plays a stirring role during the rotation process. The scraper 212 and the stirring blade 209 cooperate to mix The material in the tank 1 is stirred to mix the material. The scraper 212 drives the guide wheel 213 to rotate during its rotation. When the guide wheel 213 contacts the bottom of the filter basket 303, it can push the filter basket 303 to rise. After the guide wheel 213 is separated from the filter basket 303, the filter basket 303 is reset under the action of gravity, so that the filter basket 303 vibrates up and down during the stirring process. After the mixing is completed, the sealing plug 102 is rotated to separate the sealing plug 102 from the discharge port 101, so that the material in the mixing tank 1 can be discharged from the discharge port 101.
