Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an apparatus for processing plastic grains, and more particularly to an apparatus for transporting and cutting plastic grains that performs both operations of cutting and transporting plastic grains.

[0002]

[Prior art]

 As shown in FIGS. 1 and 2, the conventional plastic grain cutting and transporting apparatus has a structure in which a rotating cutter table 3 is installed at the inner bottom of a cylindrical pulverized raw material cylinder 2 having a hollow center. On the upper surface of the cutter base 3, a rotary blade 4 of two blades is provided. Then, the cutter table 3 is rotated by being connected to a motor 5 provided outside at the bottom of the pulverized raw material tube 2. A heating tube 6 is attached to the bottom right side of the pulverized raw material tube 2 to form a raw material inlet 7, and a screw 8 is provided inside the heating tube 6.

[0003] The operation procedure of the plastic grain cut transport device having such a structure is as follows. The plastic particles are put into the pulverized raw material cylinder 2, cut by the two blade rotating blades 4 on the cutter table 3, and then sent into the raw material inlet 7. The plastic particles are transported by the screw 8 and at the same time the already small-sized plastic particles are melted by the heat of the heating tube 6 and discharged from the raw material outlet 10 to be a plastic product.

[0004]

[Problems to be solved by the invention]

 However, the conventional apparatus has a problem that work cannot proceed smoothly due to structural defects described below. First, when plastic particles are put into the pulverized raw material cylinder 2 and cut by the two blade rotating blades 4 provided at an angle on the bottom end cutter table 3, the pulverized cut is incomplete and the cut plastic is cut. The size of the grains varies. Further, it is heated in the heating tube 6 and then transported to the raw material outlet 10. However, since most of the plastic solution is fine granules that are not completely dissolved, the quality is badly affected.

Second, the pressure of the raw material inlet 7 formed between the right side of the bottom end of the pulverized raw material cylinder 2 and the heating pipe 6 is larger than the acting force for pushing the raw material inlet 7, and the two blade rotating blades 4 rotate clockwise. On the other hand, when rotating to cut the plastic particles, the rotating force generated at the same time is too large. Therefore, the operation of putting the plastic particles into the raw material inlet 7 is not smooth, and it is difficult to put the raw material. At the same time, the number of plastic grains in the upper layer increases more and more, which adversely affects the rotation quality of the two-blade rotary blade 4. As described above, the two problems at the time of charging the raw materials have a bad influence on the discharge of the raw materials, and the capability of the machine cannot be fully exhibited.

On the other hand, there is another problem as follows. A screw 8 is installed in the heating tube 6 and a raw material inlet 7 is formed between the left end of the screw 8 and the pulverized raw material cylinder 2, but there is no support point there. Since the right side of the screw 8 is connected to the motor portion 11, there is no problem with the column of the motor portion 11, but there is a problem with the raw material inlet 7. In other words, since there is no support point, the weight of the screw 8 causes a problem that the screw 8 shakes greatly when rotated. Further, with only one support, there is a danger that the pressure at the raw material inlet 7 increases and the screw 8 is broken.

[0007] Therefore, in order to solve the above-mentioned problem, a main object of the present invention is to smoothly transport plastic particles at a raw material inlet. It is a further object of the present invention to stabilize screw rotation and prevent breakage.

[0008]

[Means for Solving the Problems]

 In view of the above problem, the plastic grain cutting and transporting device according to the first aspect of the present invention is configured such that a raw material inlet is installed in front of a ground raw material tube, and a raw material inlet is provided between the raw ground material tube and the raw material inlet stage. The cylinder has a hollow cylindrical inside, and a cutter base that can rotate in conjunction with a motor is provided at the bottom of the cylinder, and three or more blade crushing rotary blades arranged in a circumferential array are provided on the cutter base, and plastic cylinders are provided. In addition to the crushing operation, the crushing effect is obtained by combining with a non-sliding sword that protrudes from the inner wall edge of the crushed material cylinder, and the plastic material is smoothly fed into the material inlet by the rotating force of the cutter table. It can be inserted into

According to a second aspect of the present invention, there is provided a plastic grain cutting and transporting apparatus according to the first aspect, wherein a mandrel is provided at an end of the raw material inlet stand, and a bottom end of the mandrel is mounted on a base of the pulverized raw material cylinder. Insert the screw shaft end into the shaft hole provided at the upper end to form a support point, and insert a heating tube into the raw material inlet table on the opposite side of the shaft table to insert plastic particles. Is heated and transported to the raw material outlet by a screw. For this reason, the rotation of the screw is stabilized, and the risk of breakage of the screw is reduced.

[Embodiment of the invention]

 Hereinafter, a preferred embodiment of a plastic grain cut transport device according to the present invention will be described with reference to the drawings.

As shown in FIGS. 3 and 4, the raw material inlet table 12 is provided in front of the pulverized raw material cylinder 13, and a raw material inlet 14 is provided between the pulverized raw material cylinder 13 and the raw material inlet table 12. The pulverized raw material cylinder 13 has a hollow cylindrical interior, and is provided with a cutter base 16 rotatable in conjunction with a motor 15 at the bottom thereof. On the cutter table 16, three blade crushing rotary blades 17 are arranged in a circumferential arrangement to perform a crushing operation on the plastic particles. Further, a non-sliding sword 18 protruding from the inner wall edge of the crushed material cylinder 13 is provided in order to enhance the effect of crushing cut in combination with the three-blade crushing rotary blade 17. Further, the plastic can be smoothly introduced into the raw material inlet 14 by the rotational force of the cutter table 16. The crushing rotary blade of the cutter base 16 does not need to be configured with three blades, but may be configured with three or more blades.

On the other hand, a mandrel 19 is provided at the left end of the raw material inlet stand 12, and the bottom end thereof is supported in combination with the base 20 of the pulverized raw material cylinder 13. At the same time, the left end 22 of the center axis of the screw 21 is inserted into a shaft hole provided at the upper end, and is used as a support point on the left side to further stabilize the screw 21. A heating tube 23 is inserted into the right side of the raw material inlet table 12 to heat the plastic particles so that the plastic particles can be transported to the raw material outlet 24 by an internal screw 21.

[0013]

[Effect of the invention]

 By using a combination of a three-blade rotary blade on the cutter table and a stop sword protruding from the inner wall edge of the crushed material cylinder, plastic grains are cut on the inner wall surface when the cutter table rotates. Thus, the effect of complete crushing can be achieved. In addition, a raw material inlet table is provided at the front end of the crushed raw material cylinder, and the combination of the counterclockwise rotation of the cutter table and the rotation of the screw is activated to smoothly transport the plastic particles at the raw material inlet and prevent clogging of the material. Transportation becomes smooth. Furthermore, since the headstock on the left side of the raw material inlet stand is used as the support point of the mandrel on the left side of the screw, the screw rotates stably. Thus, the risk of screw breakage is reduced.
