Description

Technical Field

[0001] The utility model relates to the technical field of pelletizers, in particular to a wheel-type masterbatch pelletizer. Background Art

[0002] Masterbatch is a new type of special colorant for polymer materials. The masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly loading an extraordinary amount of pigment in a resin. Its tinting power is higher than the pigment itself. When processing, a small amount of masterbatch and uncolored resin are mixed to achieve a colored resin or product with a designed pigment concentration. The last step in the preparation of masterbatch is cutting and granulation. A pelletizer is often used. The common masterbatch pelletizer is composed of at least a chassis, a driving mechanism, upper and lower pressure wheels, a fixed knife and a rotary knife. The upper and lower pressure wheels feed the plastic strips into the pelletizing part, and the high-speed rotating rotary knife cooperates with the fixed knife to cut the plastic into granules. When the rotary knife of the existing pelletizer cuts the masterbatch plastic for a long time, the blade is often worn and needs to be replaced. However, the unworn part of the blade wheel group can continue to be used, and the blades are mostly integrally formed and fixed on the transmission shaft. It is inevitable to replace all of them, which is very wasteful. Therefore, a wheel-type masterbatch pelletizer is proposed. Utility Model Content

[0021] A wheel-type masterbatch pelletizer provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0022] Example:

[0023] Combination Figure 1-5 As shown, the utility model provides a wheel-type masterbatch pelletizer, including a shell 1, a discharge port 2 is provided on one side of the shell 1, a servo motor 3 is fixedly installed inside the shell 1, a rubber belt 4 is sleeved on the transmission end of the servo motor 3, and a pulley 5 is sleeved on one end of the rubber belt 4. When the servo motor 3 is started and starts to rotate, the pulley 5 will be indirectly driven to rotate under the action of the rubber belt 4 to realize transmission, so that the device can operate, a feed port 6 is provided on one side of the shell 1, and a guide wheel 7 is fixedly installed at a position near the feed port 6 on one side of the shell 1. The cooled strip plastic masterbatch is transported to the guide wheel 7 by a conveyor, and a plurality of grooves are also provided on the surface of the guide wheel 7, so that the strip masterbatch can be guided into the feed port 6 to wait for pelletizing, so as to avoid the strip masterbatch being stuck in the periphery of the pelletizer and unable to enter, thereby affecting pelletizing, a lower pressing wheel 8 is clamped inside the shell 1, and an upper pressing wheel 9 is arranged near the upper part of the lower pressing wheel 8 inside the shell 1.

[0024] Among them, the upper pressing wheel 9 includes a rotating rod 901, a first nut 904, and a second nut 905. Limiting holes are provided on both sides of the shell 1. The two ends of the rotating rod 901 are sleeved with the limiting holes. The two ends of the rotating rod 901 are threadedly connected with the first nut 904 and the second nut 905. The rotating rod 901 is stuck in the shell 1. Under the rotation and extrusion of the first nut 904 and the second nut 905, the first nut 904 and the second nut 905 are tightly fitted into the shell 1 to clamp the shell 1, so that the upper pressing wheel 9 can be stably placed in the shell 1. At the same time, due to the provision of the limiting holes, the upper pressing wheel 9 can be adjusted at will to smoothly clamp strip masterbatches of different sizes. The upper pressing wheel 9 includes a circular groove 903. The surface of the upper pressing wheel 9 is sleeved with the circular groove 903. A plastic shell 902 is provided on the surface of the circular groove 903. Under the guidance of the plastic shell 902, the strip masterbatch can smoothly reach the cutting area. The surface structure of the upper pressing wheel 9 is consistent with that of the lower pressing wheel 8, except that the lower pressing wheel 8 cannot be adjusted.

[0025] Furthermore, a splash plate 10 is fixedly installed inside the shell 1, and the masterbatch after being cut will splash everywhere. The splash plate 10 can prevent the cut masterbatch from flying around, thereby avoiding the loss and waste of the masterbatch. A fixed block 11 is fixedly installed inside the shell 1, and a ramp plate 12 is fixedly connected to the bottom of the fixed block 11. The bottom of the discharge port 2 is fixedly connected to the ramp plate 12, and the cut masterbatch will flow out from the discharge port 2 along the ramp plate 12 to avoid falling into the inside of the shell 1 and affecting the collection. A fixed knife 24 is fixedly installed on the top of the fixed block 11, and the fixed knife 24 cooperates with the rotating blade to cut the hard strip masterbatch into small particles for easy transportation. A circular fixing part 13 is fixedly installed at one end of the pulley 5, and a limited position pile 14 is fixedly connected to one side of the circular fixing part 13. A transmission shaft 15 is fixedly installed in the middle of the circular fixing part 13, and a connecting part 16 is sleeved on the surface of the transmission shaft 15. A center hole 23 is provided in the middle of the member 16, and the interior of the center hole 23 is fixedly sleeved with the transmission shaft 15, that is, when the pulley 5 rotates, the transmission shaft 15 and the connecting member 16 will be synchronously driven to rotate. A strip groove 17 is provided on the surface of the connecting member 16, and a rotary cutter wheel group 18 is sleeved inside the strip groove 17. When the connecting member 16 rotates, the rotary cutter wheel group 18 will be synchronously driven to rotate to cut and granulate the masterbatch. Hole-shaped grooves 19 are provided at both ends of the rotary cutter wheel group 18. A circular plate 20 is fixedly sleeved at one end of the rotary cutter wheel group 18, and one side of the circular plate 20 is fixedly connected to the limit pile 14. The two ends of the rotary cutter wheel group 18 are sleeved with the limit pile 14. Under the clamping of the circular fixing member 13 and the circular plate 20, the assembly of the rotary cutter wheel group 18 and the connecting member 16 can be stably fixed to achieve rotary cutting. A large nut 21 is threadedly connected to one end of the transmission shaft 15, and a bearing 22 is fixedly connected to one side of the large nut 21.

[0026] The working principle and use process of the utility model are as follows: first, when masterbatch of unqualified size is detected, that is, the cutter wheel group 18 is damaged, the power is turned off at this time, and when the pulley 5 stops running, the bearing 22 is removed, and the large nut 21 is rotated and unscrewed to move the circular plate 20 out. At this time, the damaged blade in the cutter wheel group 18 is checked, and it is pulled out from the strip groove 17, and then the new blade is inserted into the position of the original strip groove 17. At this time, the circular plate 20 is installed with one side of the limit pile 14 aligned with the cutter wheel group 18, and the limit pile 14 is further aligned with the hole-shaped groove 19 for sleeve connection. At this time, the large nut 21 is rotated and tightened with the threaded end of the transmission shaft 15 to fix it.
