Description

Styrofoam shredder {STYROFOAM SHREDDING MACHINE}

The present invention relates to a styrofoam pulverizer, and especially in crushing styrofoam with high compressibility, it is difficult to grind to an appropriate size due to the unique compressibility and adhesive force of styrofoam, so that many defects occur and vibration and noise generated by high-speed rotation of the crushing plate. And it relates to a styrofoam grinder for preventing problems such as shortening the life of the machine.

In general, a styrofoam grinder is pulverized by smashing the styrofoam bundle supplied to the bundle of the appropriate size of the grinding plate rotating at high speed. Here, the crushing plate of styrofoam is pulverized by pulverizing the styrofoam by the centrifugal force of high speed rotation by connecting the pulverizing plate to the main shaft which rotates at a high speed at a suitable size and a suitable interval.

A conventional typical styrofoam grinder for pulverizing styrofoam by means of a high speed rotating grinding plate is shown in FIG. 1.

In Figure 1, reference numeral 101 is a motor base, 102 is a motor, 103 is a pulley, 104 is a belt, 105 is a spacer, 106 is a grinding plate, 107 is a main shaft, 108 is a grinding plate shaft, 109 is a bearing, 110 is The connecting plate, 111 is a perforated network, 112 is a body.

As shown in FIG. 1, the conventional styrofoam grinder is connected to the driving motor 102 by the pulley 103 and the V-belt 104. The connecting plate for connecting the grinding plate shaft 108 to the rotating main shaft 107 ( 110 is mounted by the spacing 105 at appropriate intervals, and two or three grinding plate shafts 108 are assembled in the connecting plate 110 at equal intervals, and the grinding plate shaft 108 has a grinding plate. 106 is attached by the spacer 105 at equal intervals. Styrofoam is pulverized by the centrifugal force generated by the pulverizing plate 106 rotating at a high speed by the high speed rotation of the main shaft 107. On the other hand, the lower part of the main shaft 107 is provided with a perforated network 111 with a radius slightly larger than the rotation radius of the grinding plate 106 centered on the main shaft to serve to filter the crushed styrofoam Styrofoam pulverized larger than the size is repeatedly hit the crushing plate 106 to be crushed.

However, the styrofoam pulverizer crushing the styrofoam by the above device is crushing the styrofoam with tremendous centrifugal force by the high-speed rotation of the crushing plate 106, but the size of the crushed styrofoam is unstable due to the unstable size of the crushing efficiency decreases Machine and device breakdown is frequently caused by rotation, and the perforated network is frequently blocked by styrofoam that is not crushed under the proper size, and the perforated network is damaged by pinching of styrofoam between the grinding plate 106 and the perforated network 111. There is a lot of work that takes a lot of time to repair the perforation network.

The present invention has been devised in view of the problems of the prior art as described above, and has a large number of trapezoidal blades instead of crushing the styrofoam with high compressive strength and strong adhesive force by pulverizing plate with a large centrifugal force by high speed rotation. It can be crushed to the right size by cutting and crushing using a rack die that can be adjusted to the cutter and the proper clearance, minimizing the defect rate and eliminating the need for high speed spindle rotation. The purpose of the present invention is to provide a styrofoam grinder that can significantly improve productivity while increasing the output per unit time.

Specific means for achieving the above object;

This is achieved by forming a lot of polygonal blades in a multi-tiered multi-faceted cutter and using a rack die to engage the cutter blades to adjust the gap of the teeth.

The styrofoam grinder according to the present invention is basically the same as the general styrofoam grinder as shown in FIG. There is a cutter (6) for crushing styrofoam, a perforated network (30) for filtering the crushed styrofoam, a rack die (19) for adjusting the intermeshing gap and the elm block (25) for perforating the upper and lower perforations of the present invention, rotary for refrigerant supply The styrofoam pulverizer according to the present invention has the styrofoam supplied to the top of the crusher by rotating the guide plate 18 and the cutter 6, respectively. 37. The styrofoam pulverized product dropped into the perforated net 30 and fell through the perforated net of the cutter blade 7 and the rack die 19 which rotates in the direction of rotation to the perforated net 30 passes through the perforated net. What is transferred to the process and not passed through the perforated net is conveyed to the grinding position by the rotation of the cutter and pulverized. Hereinafter, the configuration of the present invention will be described in detail. Is assembled by sliding fitting to a cutter drum 8 welded to a main shaft 9 supported by a fixed side bearing 11 on the right side of the machine and a support side bearing 13 on the left side of the machine and the cutter 6 It is divided into 400mm long for easy manufacturing and handling. The surface of the cutter has a multi-polygonal cutter blade (7) formed in multiple rows, and the cutter blade is shown in Fig. 3 in consideration of workability and styrofoam cutability. Likewise, it is safe to have a side shape of an isosceles trapezoid and a plane shape close to the trapezoid, and the height of the cross section cutter blade 7 is 3 to 5 as shown in FIG. The limiter is suitable, and the pitch between the radial cutter blades (7) is 10 to 15 millimeters, and the pitch between the axial cutter blades (7) is about 4 to 7 millimeters. Care should be taken when the valley between pitches is acute, as the crushed styrofoam is jammed. On the other hand, the size of the cutter 6 is enough to set a diameter of 300 millimeters and a length of 1600 millimeters in the case of aiming a grinding amount of 5 to 10 cubic meters per hour. The main spindle 9 supporting the cutter and transmitting the rotational force serves to transmit the output of the motor 2 to the cutter 6 and to remove heat, which is the root cause of many problems occurring in the styrofoam grinder. The hollow shaft is manufactured to serve as a delivery passage of the refrigerant, and a rotary joint 14 is installed at a supporting side end of the main spindle 9 to supply the refrigerant. In order to transfer the refrigerant to the heat source, the main spindle 9 has a plurality of holes for delivering the refrigerant of the appropriate size in the radial direction, and the heat sources to which the refrigerant is to be transferred are bearings (11, 13), cutter (7), There are scraper (17) contacts on both ends of the cutter. Especially, the cutter blade has a cooling effect as well as prevents clogging of crushed styrofoam, which requires a large number of small refrigerant delivery holes, and has a diameter of 300 millimeters and a length of 1600 millimeters. Cutters require more than 1000 refrigerant delivery holes with a diameter of 0.5 millimeters. In addition, an important heat source is the cutter blade (7) of the rack die (19), but there is no pipe line through the main spindle (9). Supply the refrigerant through. Refrigerants used here include water, air, vaginal gas, and freon gas. However, if water is used as a refrigerant, a separate system is required. It is safe to use dragon air.

The guide plate 18 for guiding the flow of styrofoam to the joints of the cutter blade 7 and the rack die 19 has one end assembled to the front and rear walls of the body 33 and the other end It is better to reach the root position of the tooth type of the rack die 19, and the guide surface may be roughened on the guide surface by knurling, rubber coating, punching, etc. for the holding role of crushed styrofoam. As shown in the figure, the half moon is the most common, but it can also be straight or stepped.

The rack die 19 meshed with the cutter blade 7 basically serves to stop the styrofoam coming down the guide plate 18 and the size of the styrofoam cut by the gap between the cutter blade 7 and the cutter blade 7. Plays a crucial role in determining To this end, in the present invention, as shown in Fig. 4, the pull bolt 21 and the stopper bolt 20 are provided to move the rack die 19 back and forth to finely adjust the gap with the cutter blade 7. In order to adjust the gap, first loosen the pull bolt (21) to allow the rack die (19) to move sufficiently, and then push the rack die little by little with the stopper bolts (20) on both sides to make the desired gap. Pull out (21) and fix it firmly. At this time, the clearance of the fitting part to be adjusted differs depending on the size of the cutter blade 7 and the rotation speed of the cutter 6, but about 1 to 3 millimeters is suitable. Thus, after the adjustment is completed, the fixing nut 22 and the fastening bolt are completed. (38) is to be tightened to prevent loosening due to vibration. The shape of the engagement portion of the rack die 19 is a trapezoidal shape through which the above-described cross-sectional shape of the cutter blade 7 can pass, and the thickness is not related to the size of the styrofoam to be crushed.

The perforated network 30, which primarily serves to filter the crushed styrofoam, is okay even when using a commercially available perforated network, but a rod or perforated network reinforcement bar 32 having a diameter of about 30 millimeters at both ends in the longitudinal direction so as not to be deformed. It is good to fix using. In addition, the perforated network 30 not only filters crushed styrofoam, but also serves to transport the styrofoam, which is not crushed to a desired size, back to the pulverization position by the cutter 6. In order to properly maintain and maintain this gap, a perforation network adjusting device is installed as shown in FIG. This perforating net adjusting device serves to separate the perforating net 30 from the cutter 6 for the maintenance and replacement of the perforating net 30 as well as for adjusting the clearance with the cutter 6. The perforated network adjusting device includes a clip die 26, a clip block 27, a clip bolt 29, an EL block 25, an EL guide 24, an adjusting bolt 23, a fixing nut 39, and a guide pin. 28) is mounted on the left plate of the body 33, and when adjusting the clearance of the perforation network 30, the clip bolt 26 is rotated by turning the adjusting bolt 23 to the right or left while the fixing nut 39 is loosened. Is fixed, the L block 25 is moved up and down by the L guide (24) to adjust the gap between the cutter (6) and the perforated network 30, the clip bolt for separation for replacement or repair of the perforated network (30) Loosen (29) slightly so that the perforated mesh reinforcement bar (32) can be pulled out and turn the adjusting bolt (23) to the right. It is moved to the position where the exchange of 30 is possible. The perforated network 30 moved to the perforated network exchange position for the perforated network exchange by opening the perforated network separating door in the upper left center of the styrofoam grinder and pulling out the perforated network is separated by the perforated network support block 31.

As described above, the styrofoam grinder according to the present invention is a unit by a rack die (19) capable of rotating the cutter (6) in which numerous cutter blades (7) of a polygonal polygon are formed and the engagement gap between the cutter blades (7).
