Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of three-roller machines, in particular to a three-roller machine with an adjustable discharge port. Background Art
[0002] In the related art, the three-roll mill is referred to as the three-roll mill for short. The three-roll mill can be divided into two types: experimental three-roll mill and production three-roll mill. The three-roll mill achieves the grinding effect by squeezing the surfaces of three horizontal rollers against each other and rubbing at different speeds. Since the three-roll mill is the most effective grinding and dispersing equipment for high-viscosity materials. With the development of the three-roll mill, it has been widely used in the manufacture of slurries such as paints, inks, pigments, and plastics. The relative position between the discharge port and the rollers of a traditional three-roll mill is generally not adjustable. This will make it impossible for the discharge port to efficiently collect the material on the rollers when grinding materials of different thicknesses, reducing production efficiency. Utility Model Content
[0003] The purpose of the utility model is to provide a three-roller machine with an adjustable discharge port to solve the problems raised in the above background technology.
[0004] In view of the above problems, the technical solution proposed by the present invention is:
[0005] A three-roller machine with an adjustable discharge port comprises a machine body, an adjustment mechanism, and a shielding mechanism, wherein the machine body comprises a chassis, three groups of grinding rollers are rotatably connected inside the chassis, a driving member is installed on the outside of the chassis, and the driving member drives the three groups of grinding rollers to rotate independently, an opening is provided on the side of the chassis, a discharge member is slidingly provided inside the chassis below the three groups of grinding rollers, the discharge member has a discharge port, and the discharge port is located in the opening, the adjustment mechanism adjusts the height of the discharge member, and the shielding mechanism comprises a first connecting strip installed on the top surface of the opening, the interior of the first connecting strip is connected to a first reel via a coil spring, a first shielding cloth is wound on the outside of the first reel, and the free end of the first shielding cloth is installed on the top surface of the discharge member.
[0006] The beneficial effect of adopting the above further solution is that the adjustment mechanism is used to ensure that the tail end of the discharge piece can always contact the material on the end grinding roller, thereby scraping the material on the end grinding roller. In this way, when grinding materials of different thicknesses, the material on the roller can be efficiently collected.
[0007] Furthermore, the adjustment mechanism includes a limit bar installed at the bottom of the chassis, the interior of the limit bar is connected to a first threaded rod and a second threaded rod through a bearing, the threads of the first threaded rod and the second threaded rod are opposite to each other, a coupling is connected between the first threaded rod and the second threaded rod, the outer sides of the first threaded rod and the second threaded rod are respectively threadedly engaged with a second connecting block and a fourth connecting block, and the second connecting block and the fourth connecting block slide inside the limit bar, the bottom surface of the discharge piece is installed with a first connecting block and a third connecting block, a first connecting rod is rotatably connected between the first connecting block and the second connecting block, and a second connecting rod is rotatably connected between the third connecting block and the fourth connecting block. Furthermore, an organic box is installed on the outer side of the chassis, a motor is installed inside the machine box, the output end of the motor is transmission-connected to the second threaded rod, and a plurality of heat dissipation slots are provided on the outer side of the machine box.
[0008] Furthermore, the first connecting block, the second connecting block, the third connecting block and the fourth connecting block all have grooves, and pins are rotatably connected in the grooves. Both ends of the first connecting rod and the second connecting rod are installed on the outside of the pins.
[0009] The beneficial effect of adopting the above further scheme is that the motor drives the first threaded rod and the second threaded rod to rotate synchronously. Because the threads of the first threaded rod and the second threaded rod are opposite to each other, the second connecting block and the fourth connecting block will move in opposite directions, so the first connecting rod and the second connecting rod will rotate, thereby changing the height of the discharge piece.
[0010] Furthermore, the discharge part includes a discharge plate, the top surface of the discharge plate is a slope, a connecting frame is installed on one side of the top surface of the discharge plate, the discharge port is located in the connecting frame, the first connecting block and the third connecting block are installed on the bottom surface of the discharge plate, and the free end of the first shielding cloth is installed on the top surface of the connecting frame.
[0011] The beneficial effect of adopting the above-mentioned further solution is that the four sides of the discharge plate are in contact with the inner wall of the chassis, so the material cannot flow out of the gap between them. Because the first shielding cloth is wrapped around the outside of the first reel that can be reset, when the discharge plate is raised or lowered, the first shielding cloth can always cover the space between the connecting frame and the opening. At the same time, the two sides of the connecting frame are in contact with the side walls of the opening, so the material can only flow out from the discharge port. Furthermore, the shielding mechanism also includes a second connecting strip mounted on the bottom surface of the opening. The interior of the second connecting strip is connected to the second reel via a coil spring. The outside of the second reel is wound with a second shielding cloth. The free end of the second shielding cloth is mounted on the bottom surface of the discharge plate.
[0012] The beneficial effect of adopting the above further solution is that since the second shielding cloth is wound around the outside of the second reel that can be reset, when the discharge plate is raised or lowered, the second shielding cloth can always cover the space between the discharge plate and the opening, thereby preventing dust from adhering to the first threaded rod and the second threaded rod.
[0013] Furthermore, a hopper is installed on the top surface of the chassis.
[0014] The beneficial effect of adopting the above-mentioned further scheme is that the hopper is used for feeding, and the material to be ground is added between the grinding roller at the head end and the grinding roller in the middle section. The driving part drives the three sets of grinding rollers to rotate independently, and the speeds are different. In this way, after the grinding roller at the head end and the grinding roller in the middle section have ground the material, the material will adhere to the grinding roller in the middle section and be ground by the grinding roller in the middle section and the grinding roller at the tail end, and the tail end of the discharge plate is squeezed with the grinding roller at the tail end. When the grinding roller at the tail end rotates, the material attached to the grinding roller at the tail end can be scraped off, and the material slides on the inclined surface and flows out from the discharge port.
[0015] Compared with the prior art, the beneficial effect of the present invention is that the three-roller machine with an adjustable discharge port uses an adjustment mechanism to ensure that the tail end of the discharge piece can always contact the material on the end grinding roller, thereby scraping the material on the end grinding roller. In this way, when grinding materials of different thicknesses, the material on the roller can be efficiently collected. BRIEF DESCRIPTION OF THE DRAWINGS
