Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, in particular to a feeding device for the production and processing of crystalline epoxy resin coatings. Background Art

[0002] Crystalline epoxy resin coatings may be in a crystalline state at room temperature or low temperature. Their crystallization characteristics will affect the fluidity of the material. Compared with ordinary liquid or powdered coating raw materials, they are more prone to problems such as blockage and uneven flow during the feeding process. The chemical stability and viscosity of the coating also require that contamination or excessive stirring be avoided during the feeding process. Therefore, a feeding device for the production and processing of crystalline epoxy resin coatings is required for feeding.

[0003] However, during the use of the existing feeding device for the production and processing of crystalline epoxy resin coatings, due to the uneven particle size in the raw materials, the larger particles of crystalline raw materials directly enter the production and processing links, which will lead to uneven microstructure of the coating. During the coating film formation process, the distribution of the resin matrix around the larger particles is different from that around the small particles, thereby affecting the physical properties of the film layer. Utility Model Content

[0004] The purpose of the utility model is to provide a feeding device for the production and processing of crystalline epoxy resin coatings. By setting a vibrating screening mechanism, the utility model solves the problem that during use of the existing feeding device for the production and processing of crystalline epoxy resin coatings, due to the uneven particle size in the raw materials, the larger particles of crystalline raw materials directly enter the production and processing links, which will lead to uneven microstructure of the coating. During the film-forming process of the coating, the distribution of the resin matrix around the larger particles is different from that around the small particles, thereby affecting the physical properties of the film layer.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a feeding device for producing and processing crystalline epoxy resin coatings, comprising a feeding pipe, on which a vibration screening mechanism and a feeding mechanism are provided;

[0007] A screening box is provided above the feed pipe, a funnel is fixedly connected to the bottom of the screening box, a connecting pipe is provided at the bottom of the funnel, the bottom of the connecting pipe is connected to the feed pipe, a fixing sleeve is fixedly connected to the outer wall of the feed pipe, the top of the fixing sleeve is fixedly connected to the screening box, the vibrating screening mechanism includes a vibrating screening assembly and a reset assembly, the vibrating screening assembly includes a screening plate slidably connected to the inner wall of the feed pipe, a rotating shaft 1 is rotatably connected to the right inner wall of the feed pipe, and the left side of the rotating shaft 1 rotates and extends outside the screening box.

[0008] Furthermore, an eccentric wheel is fixedly connected to the outer wall of the rotating shaft 1, and a U-shaped adapter block is fixedly connected to the bottom of the screening plate, and the eccentric wheel is adapted to the U-shaped adapter block.

[0009] Furthermore, the reset assembly includes trapezoidal sliders fixedly connected to the front and rear inner walls of the screening box respectively, and trapezoidal slide grooves are provided on the front and rear sides of the screening plate. The sides of the two trapezoidal sliders close to each other slide and extend into the two trapezoidal slide grooves respectively.

[0010] Furthermore, U-shaped support plates are fixedly connected to the left and right inner walls of the feeding pipe, the bottoms of the two U-shaped support plates are fixedly connected to telescopic rods, and the bottoms of the two telescopic rods are fixedly connected to the screening plate.

[0011] Furthermore, springs are sleeved on the outer walls of the two telescopic rods, the tops of the two springs are fixedly connected to the two U-shaped support plates respectively, and the bottoms of the two springs are fixedly connected to the screening plate.

[0012] Furthermore, the feeding mechanism includes a second rotating shaft rotatably connected to the left inner wall of the feeding pipe, the left side of the second rotating shaft rotates and extends outside the feeding pipe, and a screw dragon piece is fixedly connected to the outer wall of the second rotating shaft.

[0013] Furthermore, a motor is provided on the left side of the feeding tube, the output shaft of the motor is fixedly connected to the second rotating shaft through a coupling, a motor sleeve is fixedly connected to the outer wall of the motor, and the right side of the motor sleeve is fixedly connected to the feeding tube.

[0014] Furthermore, pulleys are fixedly connected to the left extensions of the second rotating shaft and the first rotating shaft, and belts are sleeved on the two pulleys.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up a vibrating screening mechanism, when it is necessary to add materials, the motor can be started, and the motor drives the second shaft to rotate. When the second shaft rotates, it will drive the first shaft to rotate through the pulley and the belt. When the first shaft rotates, the first shaft will drive the eccentric wheel to rotate. When the raised part of the eccentric wheel rotates to contact the U-shaped adapter block, the screening plate will move upward under the mutual cooperation of the eccentric wheel and the U-shaped adapter block. At this time, the spring on the telescopic rod will undergo elastic deformation and be compressed to generate elastic force. When the eccentric wheel disengages from the U-shaped adapter block, the screening plate will be reset under the action of the elastic force of the spring. This reciprocating motion generates vibration, which makes it possible to continuously rearrange the raw material particles, and smaller particles are more likely to pass through the sieve holes, thereby improving the screening efficiency and ensuring that only particles that meet the requirements enter the subsequent production and processing links. Large particles and small particles can be accurately separated, thereby improving the quality stability of the product.

[0017] 2. By setting up a feeding mechanism, the material that has been screened after vibration will enter the feeding pipe through the funnel and the connecting pipe under the action of its own gravity. At this time, since the second shaft is rotating, the rotation of the second shaft will also drive the auger piece to rotate, thereby conveying the required added material into the required feeding device, so that it can be ensured that the material can continuously and stably enter the required feeding device. The action of gravity initially guides the material, and the auger piece further pushes the material to overcome possible resistance, thereby ensuring the reliability of material transmission. The auger piece continuously pushes the material forward in the feeding pipe, keeping the material in a loose state, preventing it from stagnant accumulation in the feeding pipe and blocking the pipeline, thereby ensuring the smooth flow of the material transmission channel.

[0029] The feeding mechanism 3 includes a second rotating shaft 301 rotatably connected to the inner wall of the left side of the feeding tube 1, the left side of the second rotating shaft 301 rotates and extends to the outside of the feeding tube 1, and a screw piece 302 is fixedly connected to the outer wall of the second rotating shaft 301. A motor 303 is provided on the left side of the feeding tube 1, and the output shaft of the motor 303 is fixedly connected to the second rotating shaft 301 through a coupling. A motor sleeve 304 is fixedly connected to the outer wall of the motor 303, and the right side of the motor sleeve 304 is fixedly connected to the feeding tube 1. The second rotating shaft 301 and the left extension of the rotating shaft 1 212 are both fixedly connected. It is connected to a pulley 305, and a belt 306 is provided on the two pulleys 305. By setting up a feeding mechanism 3, it is ensured that the material can continuously and stably enter the device for required feeding.

[0030] A specific application of this embodiment is as follows: when in use, first connect the right side of the feeding pipe 1 to the device for adding the required material, pour the required material onto the screening plate 211 in the screening box 101, and then start the motor 303. The motor 303 drives the second rotating shaft 301 to rotate. When the second rotating shaft 301 rotates, the first rotating shaft 212 is driven to rotate through the pulley 305 and the belt 306. When the first rotating shaft 212 rotates, the first rotating shaft 212 drives the eccentric wheel 213 to rotate. When the raised part of the eccentric wheel 213 rotates to contact the U-shaped adapter block 214, the screen plate 211 will move upward under the cooperation of the eccentric wheel 213 and the U-shaped adapter block 214. At this time, the spring 225 on the telescopic rod 224 will be elastically deformed and compressed to generate elastic force. When the eccentric wheel 213 is separated from the U-shaped adapter block 214, the screen plate 211 will be reset under the action of the elastic force of the spring 225, and the reciprocating vibration is generated, so that the raw material particles can be continuously re-set. The new arrangement makes it easier for smaller particles to pass through the sieve holes, thereby improving screening efficiency and ensuring that only particles that meet the requirements enter the subsequent production and processing links. It can accurately separate large particles from small particles, thereby improving product quality stability. After vibration, the screened material will enter the feed pipe 1 through the funnel 102 and the connecting pipe 103 under the action of its own gravity. At this time, since the second shaft 301 is rotating, the rotation of the second shaft 301 will also drive the auger piece 302 to rotate, thereby transferring the required added material into the required feeding device, so that it can be ensured that the material can continuously and stably enter the required feeding device. The action of gravity initially guides the material, and the auger piece 302 further pushes the material to overcome possible resistance, thereby ensuring the reliability of material transmission. The auger piece 302 continuously pushes the material forward in the feed pipe 1, so that the material remains loose, preventing it from stagnantly accumulating in the feed pipe 1 and blocking the pipeline, thereby ensuring the smooth flow of the material transmission channel.
