Description

Technical Field

[0001] The invention relates to the technical field of grinder application, in particular to a three-roll grinder for adhesive production. Background Art

[0002] Three-roller grinding machine is mainly used for grinding various liquid slurries and paste materials such as paints, inks, pigments, plastics, cosmetics, soaps, ceramics, rubber, etc. The three-roller grinding machine has three rollers installed on an iron frame with the center in a straight line. It can be installed horizontally or slightly tilted. The grinding effect is achieved by the mutual extrusion of the surfaces of the three horizontal rollers and the friction at different speeds. After grinding, the material is scraped off by the scraper installed in front of the front roller. Due to the different rotation directions of the three rollers (the speed increases from back to front), a good grinding effect is produced. Adhesive is one of the most important auxiliary materials in packaging operations and is widely used in packaging operations. Adhesive has A sticky substance can connect two separate materials together with the help of its sticky properties. There are many types of adhesives. In the adhesive production process, a three-roll grinder is often used. However, the color paste on the first grinding roller and the second grinding roller is conducted by the grinding contact between the grinding rollers. If the last part of the residual color paste is not cleaned up, it will cause the color paste to form on the grinding roller, affecting the next grinding work. The staff is required to wipe it to ensure the next use of the grinding roller. After each operation of the three-roll grinder, the staff is required to clean the grinding roller, which is troublesome, resulting in poor grinding efficiency and affecting the processing effect. For this reason, we proposed a three-roll grinder for adhesive production. Summary of the invention

[0038] In the present invention, a plurality of support plates 18 are fixedly connected to an array on one side of the linkage plate 17, and water spray panels 19 are respectively fixedly connected to the plurality of support plates 18.

[0039] In the present invention, the transmission mechanism includes a first pulley 33 fixedly connected to the output shaft of the driving motor 32, a second pulley 34 is fixedly connected to one end of the third connecting seat 4 corresponding to the first pulley 33, and the outside of the second pulley 34 is connected to the outside of the first pulley 33 by the same belt 35.

[0040] In the present invention, the linkage mechanism includes a first bevel gear 27 fixedly connected to one end of the first connecting seat 2, a linkage rod 26 is rotatably connected to one side of the body 1, one end of the linkage rod 26 is fixedly connected to the second bevel gear 39 corresponding to the first bevel gear 27, one side of the second bevel gear 39 is meshed with the first bevel gear 27 for transmission, the other end of the linkage rod 26 is fixedly connected to the sprocket 28, one end of the bidirectional reciprocating screw rod 12 is fixedly connected to the one-way sprocket 29 corresponding to the sprocket 28, and the same chain 30 is transmission-connected between the one-way sprocket 29 and the sprocket 28.

[0041] In the present invention, the top of the body 1 is symmetrically fixedly connected with a threaded rod and a limit rod, and the two threaded rods and the limit rod are respectively movably provided with a limit plate 36, a material guide plate 37 is installed on one side of the interior of the body 1, a drainage plate 38 is fixedly connected to the lower part of the interior of the body 1, and the bottom array of the body 1 is fixedly connected to a support column.

[0042] Working principle: during use, when it is necessary to grind the adhesive, the two limit plates 36 are fixedly installed on the upper part of the machine body 1. After being fixed, the first pulley 33 is driven to rotate forwardly by the positive start of the driving motor 32. The positive rotation of the first pulley 33 drives the second pulley 34 to rotate forwardly synchronously through the belt 35. The positive rotation of the second pulley 34 drives the third connecting seat 4 to rotate forwardly synchronously. When the positive rotation of the third connecting seat 4 drives the third grinding roller 7 to rotate synchronously, the rotation of the third grinding roller 7 drives the rotation of the third gear plate 10. At the same time, through the meshing transmission with the second gear plate 9 and the first gear plate 8, the first grinding roller 5 and the second grinding roller 6 are driven to rotate synchronously respectively, so as to grind the adhesive. At the same time, the ground adhesive is scraped off from the first grinding roller 5 through the guide plate 37.

[0043] When it is necessary to clean the surfaces of the first grinding roller 5, the second grinding roller 6 and the third grinding roller 7, the two limit plates 36 are removed, and the reverse start of the driving motor 32 drives the first pulley 33 to rotate in the reverse direction, and at the same time drives the third grinding roller 7 to rotate in the reverse direction, thereby driving the first grinding roller 5 to rotate, and the rotation of the first grinding roller 5 drives the rotation of the first connecting seat 2, and the rotation of the first connecting seat 2 drives the reverse rotation of the first bevel gear 27, and the reverse rotation of the first bevel gear 27 is meshed with the second bevel gear 39 for transmission, and the rotation of the second bevel gear 39 drives the rotation of the connecting rod 26, and the reverse rotation of the connecting rod 26 drives the reverse rotation of the sprocket 28, and at the same time drives the reverse rotation of the one-way sprocket 29 through the chain 30. When the grinding process is performed, when the driving motor 32 is started in the forward direction, the one-way sprocket 29 rotates in the forward direction, and when the one-way sprocket 29 rotates in the forward direction, it does not mesh with the bidirectional reciprocating screw rod 12 for transmission. Therefore, when the grinding process is performed, the bidirectional reciprocating screw rod 12 remains stationary;

[0044] When the one-way sprocket 29 rotates in the opposite direction, it meshes and rotates with the two-way reciprocating screw 12, thereby driving the rotation of the two-way reciprocating screw 12. The rotation of the two-way reciprocating screw 12 drives the two moving frames 13 to move relatively in the opposite directions along the guide rod 31. The movement of the two moving frames 13 drives the telescopic fence 14 to extend and retract, thereby driving the two sliding blocks 15 to move synchronously along the sliding rod 16. The movement of the sliding block 15 drives the linkage plate 17 to extend and retract, and at the same time drives the scraper 20 to reciprocate synchronously, thereby scraping and cleaning the surfaces of the first grinding roller 5, the second grinding roller 6 and the third grinding roller 7. The water spray panel 19 sprays the cleaning liquid, and the surfaces of the first grinding roller 5, the second grinding roller 6 and the third grinding roller 7 are sprayed and cleaned by the cleaning liquid. After the surfaces of the first grinding roller 5, the second grinding roller 6 and the third grinding roller 7 are cleaned, the electric heating ring 25 is energized for heating. After the electric heating ring 25 is energized, the first grinding roller 5, the second grinding roller 6 and the third grinding roller 7 are heated, thereby drying the first grinding roller 5, the second grinding roller 6 and the third grinding roller 7, effectively ensuring that the surfaces of the first grinding roller 5, the second grinding roller 6 and the third grinding roller 7 are dry, avoiding rust due to moisture, which affects the later use effect.
