Description

Technical Field

[0001] The utility model relates to the technical field of epoxy resin processing equipment, in particular to an automatic proportioning device for epoxy resin. Background Art

[0002] Epoxy resin is a high molecular polymer. Generally, epoxy resin needs to be mixed with other chemical materials to make it into a liquid glue with strong viscosity. Epoxy resin has the characteristics of high strength, strong adaptability, and waterproof and oil-proof. By mixing epoxy resin, curing agent and fatty acid in a certain proportion, commonly used floor paint can be produced. Floor paint has the characteristics of wear resistance, corrosion resistance and oil resistance. When mixing existing epoxy resins, it is necessary to rely on the experience of employees to mix the appropriate proportion. When employees lack experience, the ratio is likely to be unbalanced, resulting in a thinner epoxy resin formula and poor adhesion.

[0003] The utility model patent with publication number CN 221108240 U discloses a raw material layered proportioning structure for preparing modified epoxy resin. In this scheme, a reaction tank is set up, the outer wall of the reaction tank is fixedly connected to a connecting seat, the bottom of the connecting seat is fixedly connected to an annularly distributed support leg, the upper surface of the reaction tank is fixedly installed with a top cover, the top cover is vertically limited and slidably connected to a mounting frame, and the mounting frame is provided with a proportioning mechanism; by setting a discharge port on the discharge pipe to discharge the material to different positions in the reaction tank, the raw materials are fully contacted with the basic epoxy resin, and the stirring shaft in the reaction tank is cooperated with the stirring shaft to stir, so as to prevent the raw materials from being continuously discharged at the same position and accumulating and agglomerating, so that the basic epoxy resin, functional modifier, filler and other raw materials can be fully mixed, and the discharge speed is controlled to further prevent the raw materials from accumulating and agglomerating in the reaction tank, so that the raw materials at different layers can be fully mixed.

[0004] However, the above solution still has some shortcomings. For example, in the above solution, the feeding speed is controlled by driving the spiral blade by a motor. However, the spiral blade rotated by the motor still requires the operator to manually control the feeding amount. When the operator makes an error in operation, it will still lead to different mixing ratios, affecting the uniformity of product quality. In view of this, we propose an automatic mixing device for epoxy resin. Utility Model Content

[0025] Example 1

[0026] An automatic proportioning device for epoxy resin, such as Figure 1 、 Figure 3 、 Figure 4As shown, it includes a mixing drum 1; an automatic proportioning mechanism 2 is provided on the mixing drum 1, and the automatic proportioning mechanism 2 includes a bracket 201, the bracket 201 is fixedly connected to the top of the mixing drum 1, and the bottom end of the bracket 201 is connected to a proportioning drum 202, and the interior of the proportioning drum 202 is connected to a driving rod 203, and the top end of the driving rod 203 is arranged through the bracket 201, and the middle of the driving rod 203 is fixedly connected to a first reciprocating screw rod 204, and the first reciprocating screw rod 204 is meshedly connected with a sleeve 205, and the bottom end of the sleeve 205 is fixedly connected to a piston 206. The automatic proportioning mechanism 2 can automatically proportion two different raw materials during the process of feeding the raw materials, thereby improving the feeding effect of the raw materials and reducing the uneven product quality caused by different proportions of the raw materials. The bracket 201 can support the automatic proportioning mechanism 2, and there are two or more proportioning cylinders 202. In this scheme, two are taken as an example. The proportioning cylinder 202 can load different raw materials. The driving rod 203 structure can drive the first reciprocating screw 204, and the first reciprocating screw 204 drives the piston 206 to rise and fall, thereby realizing the quantitative addition operation of the raw materials inside the proportioning cylinder 202. The top of the proportioning cylinder 202 is connected to the sealing cylinder 207, and the sealing cylinder 207 is fixedly connected to the bottom of the bracket 201. A feeding pipe 208 is fixedly connected to one side of the sealing cylinder 207. A proportioning groove 209 is opened on the side of the sealing cylinder 207. A sealing plate 210 is slidably connected inside the proportioning groove 209 to seal The cylinder 207 structure can conveniently support the proportioning cylinder 202, and the feeding pipe 208 on the side of the sealing cylinder 207 can facilitate the feeding operation of the raw materials. The piston 206 structure is a non-circular structure, and the piston 206 corresponds to the structure inside the sealing cylinder 207. In addition, the proportioning groove 209 opened on the side of the sealing cylinder 207 can be closed by a sealing plate 210, so that the opening position of the proportioning groove 209 can be conveniently controlled, thereby adjusting the output of the raw materials inside the proportioning cylinder 202 by the piston 206 to realize automatic proportioning operation. At the same time, a one-way valve can be added to the bottom end of the proportioning cylinder 202 and the feeding pipe 208, and the one-way conveying of the raw materials can be realized through the one-way valve. A dual-axis motor 211 is fixedly connected to the bracket 201.

The dual-axis motor 211 can drive the driving rod 203 and the reciprocating screw rod respectively through the output shafts at both ends. The moving seat 215 structure can be reciprocated and lifted under the drive of the second reciprocating screw rod 214. At the same time, the guide rod 216 structure can guide the moving seat 215 to prevent the moving seat 215 from rotating under the drive of the second reciprocating screw rod 214. The end of the output shaft at one end of the dual-axis motor 211 is fixedly connected to a guide rod 216, which is set through the moving seat 215. The side of the driving wheel 212 is connected with a ratchet.The top of the driving rod 203 and the top of the second reciprocating screw rod 214 are fixedly connected to a ratchet 213 that meshes with the ratchet teeth. The ratchet 213 can cooperate with the ratchet teeth so that the dual-axis motor 211 can drive the driving rod 203 to rotate in one direction or drive the second reciprocating screw rod 214 to rotate in one direction. That is, through the different rotation directions of the dual-axis motor 211, it is convenient to switch between the driving rod 203 and the second reciprocating screw rod 214. A positioning hole 217 is provided at the bottom end of the side of the driving rod 203. A positioning rod 218 is slidably connected to the positioning hole 217.

The proportioning drum 202 can be conveniently driven by the dual-axis motor 211. There are two groups of magnets 219 on the side of the moving base 215, and they are both located in the same vertical line. At the same time, the magnets 219 on the same side of the moving base 215 have opposite polarities. That is, by adjusting the position of the moving base 215, the outward or inward movement of the positioning rod 218 can be conveniently controlled.

[0027] Example 2

[0028] like Figure 2 As shown, a stirring mechanism 3 is provided inside the mixing drum 1, and the stirring mechanism 3 includes a stirring rod 301, which is fixedly connected to the bottom end of the guide rod 216, and a stirring blade 302 is fixedly connected to the side of the stirring rod 301. The stirring rod 301 structure is fixedly connected to the end of the output shaft of the dual-axis motor 211 through the guide rod 216. During the feeding process, the stirring rod 301 can be kept in continuous rotation, so that the raw materials are fully mixed. A stirring frame 303 is rotatably connected inside the mixing drum 1, and a buffer spring 304 is fixedly connected to the outside of the stirring frame 303. The end of the spring 304 is fixedly connected to a scraper 305, the inner side of the stirring frame 303 is fixedly connected to a stirring shaft 306, the top inner side of the stirring frame 303 is fixedly connected to a gear ring 307, and the outer bottom end of the mixing drum 202 is fixedly connected to a gear 308 that meshes with the gear ring 307. The gear ring 307 on the inner side of the stirring frame 303 and the gear 308 on the outer side of the mixing drum 202 are meshed with each other. When the mixing drum 202 rotates, the stirring frame 303 can be driven by the gear 308, so that the inner wall of the mixing drum 1 can be cleaned through the stirring frame 303.

[0029] When the automatic proportioning device for epoxy resin of the present invention is in use, the position of the sealing plate 210 is adjusted before loading, so that the opening position of the proportioning groove 209 corresponds to the loading ratio of the raw materials. When the loading operation is performed, the dual-axis motor 211 rotates forward, and the output shaft at the top of the dual-axis motor 211 drives the ratchet 213 and the driving rod 203 at the bottom of the ratchet 213 to rotate in one direction through the ratchet teeth on the outside of the driving wheel 212. At this time, the ratchet teeth on the outside of the driving wheel 212 of the output shaft at the bottom of the dual-axis motor 211 are in a disengaged state from the ratchet 213 at the top of the second reciprocating screw rod 214, and the first reciprocating screw rod 204 in the middle of the driving rod 203 is continuously rotating. During the movement, the sleeve 205 drives the piston 206 to continuously rise and fall. When the piston 206 descends, the piston 206 squeezes the air inside the sealing cylinder 207 from the proportioning groove 209. When the piston 206 descends to the sealing plate 210, the proportioning groove 209 is closed. The piston 206 that continues to descend continuously compresses the air inside the sealing cylinder 207 and the proportioning cylinder 202. At the same time, since the feed pipe 208 and the proportioning cylinder 202 are controlled by the one-way valve, the raw material inside the proportioning cylinder 202 is squeezed out from the outlet at the bottom of the proportioning cylinder 202. When the feeding operation is completed, the dual-axis motor 211 rotates in the opposite direction, and the ratchet on the output shaft at the bottom of the dual-axis motor 211 The teeth then mesh with the ratchet 213 at the top of the second reciprocating screw 214, and at the same time, the driving wheel 212 on the output shaft at the top of the dual-axis motor 211 disengages from the ratchet 213 at the top of the driving rod 203, and the continuously rotating second reciprocating screw 214 drives the moving seat 215 to move up and down, and switches the magnet 219 on the side. After the magnet 219 switches, the magnet 219 with the opposite polarity to the magnet 219 at the end of the positioning rod 218 switches to the same polarity as the magnet 219 at the end of the positioning rod 218, and the positioning rod 218 is then driven by the magnet to move toward the proportioning cylinder 202. When the positioning rod 218 moves to the inside of the positioning hole 217, the driving rod 2 03 is then fixed to the mixing barrel 202. When the adjustment is completed, the dual-axis motor 211 rotates forward again. When the driving rod 203 is driven, the mixing barrel 202 is driven to rotate synchronously through the positioning rod 218. At this time, the stirring rod 301 is driven by the output shaft at the bottom end of the dual-axis motor 211 and is rotated through the transmission of the guide rod 216, and the stirring frame 303 is rotated under the transmission of the gear 308 on the outside of the mixing barrel 202. The stirring blade 302 on the outside of the stirring rod 301 and the stirring shaft 306 on the inside of the stirring frame 303 can enhance the mixing effect of the raw materials. At the same time, the scraper 305 on the outside of the stirring frame 303 can prevent the raw materials from adhering to the wall of the mixing barrel 1.
