Description

Technical Field

[0001] The present application relates to the technical field of pelletizers, and in particular to a pelletizer with adjustable pelletizing size. Background Art

[0002] The plastic raw materials are extruded into strips by the extrusion equipment. In order to facilitate transportation and production, the strips of plastic raw materials need to be cooled and cut into small granules, which are generally processed by a plastic pelletizer.

[0003] The existing pelletizer includes a cutting knife and a rotating motor, and the rotating motor drives the cutting knife to cut the plastic.

[0004] With respect to the above-mentioned related technologies, the inventor believes that most of the existing pelletizers can only cut plastic raw materials into pellets of one size, and have the defect of being unable to adjust the pelletizing size. Utility Model Content

[0005] In order to be able to adjust the granulation size, the present application provides a granulator with adjustable granulation size.

[0006] The present application provides a pelletizer with adjustable pelletizing size, which adopts the following technical solution:

[0007] A pelletizer with adjustable granulation size comprises a body, wherein support seats are fixedly arranged between the four corners of the body and the ground, a first roller and a second roller are rotatably connected in the body, a first rotating motor driving the first roller and a second rotating motor driving the second roller are installed on the side wall of the body, a first rotating shaft is fixedly arranged on the circumferential side wall of the first roller, a plurality of cutting knives are arranged around the circumference of the first rotating shaft, a fixing rod is rotatably connected to one side of the cutting knife, connecting rods are fixedly arranged between both ends of the fixing rod and the second rotating shaft, linkage plates are fixedly arranged at both ends of the cutting knife, an adjusting component for adjusting the angle of the cutting knife is arranged between the linkage plate and the first rotating shaft, and a second rotating shaft is fixedly arranged on the axial side wall of the second roller.

[0008] By adopting the above technical solution, the staff changes the angle of the linkage plate by adjusting the component. The linkage plate causes the cutting knife to rotate around the fixed rod during the movement, thereby changing the angle between the cutting knife and the first rotating shaft, and then changing the spacing between the cutting knife heads. The different spacings between adjacent cutting knife heads can cut out particles of different sizes, thereby achieving the effect of being able to adjust the granulation size.

[0009] Optionally, there are two adjustment components, and the two linkage components are respectively arranged at two ends of the first rotating shaft. The linkage component includes an adjustment disk and an adjustment rod. The adjustment disk is sleeved on the first rotating roller and is rotatably connected to the first rotating shaft. There are multiple adjustment rods, and the adjustment rods correspond to the linkage plates one by one. One end of the adjustment rod is hinged to the linkage plate, and the other end of the adjustment rod is hinged to the adjustment disk. A locking nut is provided on the side of the adjustment disk away from the first rotating shaft, and the locking nut is sleeved on the first rotating roller and the two are threadedly connected.

[0010] By adopting the above technical solution, the staff rotates the adjusting disk, and the adjusting disk causes the adjusting rod to move. The adjusting rod causes the linkage plate to move during the movement, thereby changing the angle of the linkage plate. After the adjustment is completed, the staff rotates the locking nut to tighten the adjusting disk and the first rotating shaft, thereby achieving the effect of the adjusting component adjusting the angle of the linkage plate.

[0011] Optionally, an anti-skid pad is provided between the locking nut and the adjusting disk, and the anti-skid pad is sleeved on the first rotating roller.

[0012] By adopting the above technical solution, the anti-skid pad increases the friction between the locking nut and the adjusting disk, making it difficult for the locking nut and the adjusting disk to move relative to each other, thereby achieving the effect of the locking nut pressing the adjusting disk tightly.

[0013] Optionally, a mounting seat is provided under the body, support rods are fixed between the four corners of the mounting seat and the ground, a mounting groove is provided on the surface of the mounting seat facing the body, a filter plate is embedded in the mounting groove, a feed port is penetrated through the inner bottom wall of the mounting seat at the mounting groove, and a first collection box is provided below the mounting seat.

[0014] By adopting the above technical solution, the small pieces of granular plastic that have been cut fall from the machine body to the surface of the filter plate. The filter plate screens the granular plastic according to the size of the granular plastic. The granular plastic that meets the requirements falls into the first collection box through the filter plate, and the granular plastic that does not meet the requirements remains on the surface of the filter plate. After cutting, the workers collect the plastic particles that do not meet the requirements and reprocess them. Through the above structure, the effect of improving the granulation quality is achieved.

[0015] Optionally, a second collection box is disposed on one side of the mounting seat, and the mounting seat is arranged to be inclined downward toward the second collection box.

[0016] By adopting the above technical solution, the granular plastic that does not meet the requirements slides into the second collection box along the inclined direction of the mounting seat, and there is no need for workers to collect it, thereby achieving the effect of reducing the labor intensity of the workers.

[0017] Optionally, a vibration machine is installed on one side of the mounting base.

[0018] By adopting the above technical solution, the vibrator is started to vibrate the filter plate, thereby achieving the effect that the filter plate is not easy to be blocked.

[0019] Optionally, a plug hole is formed through the side wall of the mounting seat, a positioning hole is formed on the side wall of the filter plate, the plug hole is aligned with the positioning hole, bolts are provided in the plug hole and the positioning hole, and the filter plate and the mounting seat are both threadedly connected with the bolts.

[0020] By adopting the above technical solution, the filter plate and the mounting seat are fixed by bolts, so that the filter plate and the mounting seat are not easy to separate after the vibration machine is started; when the granulation size changes, it is necessary to replace the filter plate with a different aperture, and the filter plate can be removed by removing the bolts. Through the above structure, the filter plate and the mounting seat are fixed and the filter plate is easily replaced.

[0021] Optionally, a plurality of fixed blocks are fixedly provided around the circumference of the first rotating shaft, the number of the fixed blocks is the same as the number of the cutting knives and corresponds one to one, a groove is provided on the side wall of the fixed block facing the cutting knife, one side of the cutting knife is embedded in the groove, a slider is fixedly provided on the side wall of the cutting knife facing the fixed block, and a sliding groove adapted to the sliding of the slider is provided on the inner wall of the fixed block at the groove.

[0022] By adopting the above technical solution, during the process of changing the angle of the cutting knife, the cutting knife causes the slider to slide along the slide groove, thereby improving the stability of the cutting knife movement; during the cutting process of the cutting knife, the first rotating shaft causes the fixed block and the cutting knife to move together. During this process, the fixed block limits the cutting knife, thereby achieving the effect of stable cutting by the cutting knife.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The staff changes the angle of the linkage piece by adjusting the components, thereby changing the distance between the cutting knife heads by changing the angle of the cutting knife, thereby achieving the effect of being able to adjust the granulation size;

[0025] 2. The filter plate screens the granular plastic according to the size of the granular plastic and separates the granular plastic that does not meet the requirements, thereby achieving the effect of improving the granulation quality;
