Abstract

PURPOSE: An assortment device is provided to elevate recycling efficiency of waste vinyl by improving assortment performance by easily separating dirt and alien materials mixed in waste vinyl by pulverizing the waste vinyl. CONSTITUTION: A rotary blade assembly is formed by inserting a blade(64) and a spacer to be orthogonal on a rotary shaft(61) and arranging the blades at a certain interval. The blades orthogonal to each other form a group. The rotary blade assembly is rotated by being connected to a gear motor(66) with its rotary shafts(61). One of a group of rotary blade assemblies is rotated at higher speed than the other rotary blade assembly. The blades are rotated while being closed to each other with their sides, thus a cutting effect like a scissors is obtained and cutting performance is excellent. In respective rotary blade assembly, waste vinyl removal guides(70) are fixed. The bottom of the guide has a guide face with a smooth slope, thus the removed vinyl falls down by the speed rotated by the blades or a spacer. On the lower of a pulverizer(60), a transfer conveyor(80) is installed to transfer the vinyl cut by a first and a second pulverizing drums to a recycling process after pulverization.

Description

Selector

The present invention relates to a sorter to increase the recycling efficiency of the waste vinyl by finely crushed to recycle the waste vinyl to easily separate the dirt and foreign matter mixed in the waste vinyl to improve the sorting function of the waste vinyl.

Vinyl has the advantages of moldability and sealability, so it is mainly used as a wrapping paper for packing various foods or a farmhouse's vinyl house. These vinyls provide considerable convenience to daily life and allow farmers to increase their productivity and increase their income, but they are also a major contributor to environmental pollution because they do not rot easily.

In particular, in rural areas, vinyl used in the production of crops, such as vinyl houses, is exchanged after a certain period of time, and the replaced waste vinyl is collected and recycled to prevent environmental pollution. However, even if you try to recycle the vinyl by recycling equipment, the existing equipment does not separate the foreign substances and dirt mixed in the vinyl properly, and the quality of the recycled vinyl product is deteriorated. As a result, the regeneration business was not activated.

Therefore, avoiding the collection of waste vinyl has resulted in farmers incinerated or left unattended, increasing environmental pollution.

However, in recent years, due to the seriousness of environmental pollution, efforts are being made to revitalize the recycling business of vinyl. As a part of this, a sorting machine has been developed to effectively separate the wastes and foreign substances mixed with the waste vinyl and finely crush the vinyl to regenerate the recycling efficiency. To increase.

Such selectors have already been introduced in Utility Model Publication Nos. 91-3345 and 93-6956.

First, the sorting machine introduced in Utility Model Publication No. 91-3345 is provided with a top and bottom inlet roller which cuts a surface in front of a shredding drum having a plurality of blades attached to its outer circumference to form unevenness corresponding to each other. There is a net installed in the plate with a plurality of holes through which dirt passes. And the lower part of the network is in communication with the dust collector is to suck the dirt into the dust collector through the suction motor. In particular, the inlet roller is to transmit power to the chain, the spring device for adjusting the tension is installed on one side of the chain is to move up and down according to the amount of plastic passing.

With this structure, when the inlet roller supplies vinyl, the shredding drum is shredded and the shredded vinyl is rotated by the blade and is transferred to the waste vinyl collector by centrifugal force, and the dirt mixed with the waste vinyl is passed through the waste discharge hole of the net. Discharged. Subsequently, the dirt passing through the waste discharge hole by the operation of the suction motor is discharged to the dust collector.

On the other hand, Utility Model Publication No. 93-6956 has a rubber introduction roller with a rubber plate coated on its outer circumference instead of an uneven roller in the front, and consists of two shredding drums of different sizes. A fixed blade is fixed between the rubber inlet roll and the first shredding drum, and the screen for filtering dirt is not a plate structure but a screen structure by welding rods.In order to discharge the dirt effectively, the guide plate for screw conveyor and dirt removal is The air was blown through a blower fan to separate the waste and vinyl and at the same time light vinyl was sent to the waste vinyl collector. That is, the waste plastic is sent to the collector by the wind.

However, in the case of Utility Model Publication No. 91-3345, since the first inlet roller is made of metal, there is an advantage that the surface of the roller is not damaged by foreign matter mixed with waste vinyl such as stone or metal. Since the surface of the roller must be cut to form the uneven portion on the surface, it is difficult to process the uneven portion, and the plate forming the roller is thick, so that the weight goes out more than necessary, which causes the power loss.

In addition, when soil is caught in the uneven portion, frictional force is reduced, so that not only the waste vinyl is not properly transported, but also the waste vinyl is attracted by the shredding drum, and thus the shredding efficiency is lowered.

In addition, the chain that transmits power when the upper inlet roller flows up and down according to the amount of waste vinyl is tensioned by the expansion and contraction of the spring device. Therefore, when the load is large, the chain passes over the sprocket. Since it does not transmit rotational force, it does not smoothly introduce waste vinyl. In addition, since the rotational force of the upper and lower inlet rollers is different, the irregularities formed on the surface are not engaged with each other, so that the friction force is reduced. As a result, the screening effect is inferior.

Second, since the shredding drum is composed of one piece, the waste vinyl that is not shredded is wound on the drum, which reduces the waste vinyl shredding efficiency, which leads to the disadvantage of reducing the waste vinyl sorting efficiency. There is a disadvantage.

Third, when the waste is discharged to the dust collector through the suction motor, the waste vinyl cut by the shredding drum is sucked together, so the waste vinyl is not transported well to the waste vinyl container. There is a need to accumulate and not remove the dust collector and to remove it later. In addition, since a device such as a dust collector is required, there is a costly installation cost.

Fourth, because the mesh for filtering foreign matter and dirt is made of a plate perforated a plurality of holes on the surface, a lot of holes must be drilled during the manufacture of the mesh, which is cumbersome and time consuming. In addition, the strength of the plate network is weak, so the hole can not be processed large, there is a disadvantage that only through the small foreign matter and dirt and not through the bulky dirt.

In addition, since the network is formed integrally, if a part is damaged, the entire network needs to be replaced, and thus, the replacement work is difficult and cumbersome, which adds a lot of cost.

On the other hand, in the case of Utility Model Publication No. 93-6956, first, the inlet roller is attached to the surface of the roller instead of the uneven portion on the surface of the roller to reduce the weight of the roller and improve the processability, but the part of the plate made of rubber If part is damaged by foreign material such as stone or metal, it will tear in the grain direction of plate and should be replaced frequently.

In addition, since the upper inlet roller receives power through the chain from the lower inlet roller like the former inlet roller, the chain passes through the sprocket when the upper roller does not rotate well when a large load is applied due to a large amount of waste vinyl. Since it is not transmitted, waste vinyl is not smoothly transported and noise is generated when the chain splashes and crosses the sprocket.

In addition, due to the drawback of the draw roller, when the waste vinyl, which does not shred waste vinyl, is wound on the shredding drum, the shredding efficiency of the shredding drum is reduced, and at the same time, it causes the failure of the sorting machine.

In addition, since the induction roller and the crushing drum are driven by one motor, the rotation of the induction roller is rotated forward and backward to control the amount of waste vinyl in driving, and all the apparatuses rotate forward and backward together. Nevertheless, it is impossible in the structure that transmits power to the pulley and the belt because the crushing drum that rotates at high speed is stopped at the moment and there is a closed stage in which this operation is not made.

Secondly, because there are a plurality of shredding drums and a blade is installed between the shredding drum and the inlet roller, the sorting function is improved, but the two drums and the inlet roller are rotated by one motor, and in particular, the secondary Since the crushing drum is designed to rotate faster than the primary crushing drum, it is heavily loaded. In addition, because the belt is used to transfer power to the crushing drum, when a lot of load is applied in this way, a large amount of slip occurs between the pulley and the belt, resulting in power loss. The waste vinyl wound on the primary shredding drum can be kicked off by the secondary shredding drum, but the waste vinyl wound on the second shredding drum cannot be kicked off, so the manager has to remove it from time to time.

Third, since the net, that is, the screen is a structure in which a plurality of rods are welded and connected, like the cover of the plate structure described above, if a part is damaged, the entire cover needs to be replaced, which makes the replacement work difficult and cumbersome, which adds a lot of cost. have.

In addition, since two drums have one screen with the same hole size, dirt and vinyl of the primary shredding drum can be separated, but the waste vinyl to be sent to the next process by the second shredding drum cannot be filtered out. There is a lung dump that is thrown away with foreign objects and dirt.

Therefore, the present invention has been devised to solve the above-described conventional closure.

It is an object of the present invention to apply urethane on the surface of the inlet roller, operate the inlet roller and each shredding roller by each motor, and ensure the power transmitted to the upper inlet roller through the gear means which can be transmitted even during the up and down operation of the inlet roller. It can be delivered to the shredding drum at a constant speed at all times regardless of the size of the vinyl supply, and the shredding drum is composed of primary and secondary shredding drums to improve the shredding efficiency. To provide.

Another object of the present invention is to allow the replacement of the screen and the size change of the net by the assembly of a number of parts to filter the foreign matter and dirt, the screen is shredded by the primary shredding drum and the secondary shredding drum The purpose is to improve the sorting function of waste vinyl by deciding the waste vinyl.

Another object of the present invention is to be able to discharge quickly when discharging dirt.

Hereinafter, the specific structure of the present invention will be described in detail with reference to the accompanying drawings.

1 is a side view showing the structure of the sorter according to the invention, Figure 2 is a front view showing the structure of the sorter according to the invention, Figure 3 is a plan view showing the structure of the sorter according to the invention.

As shown in the front of the sorting machine of the present invention, a conveyor 10 for conveying and supplying vinyl is installed, and an inlet roller 20 is provided with an inlet roller 20 for introducing the vinyl supplied by the conveyor 10 into the inside. have. The inlet roller 20 has a pair of two rollers which are folded up and down, and is provided with two pairs in front and back. The shafts 22a and 22b of each of the upper and lower rollers 21a and 21b constituting a pair are both sides. It is condensed to the frame 14 provided perpendicularly from the main body. The upper and lower rollers 21a and 21b are coated with urethane 23 having good elasticity and good friction. The upper part of the frame 14 is formed with a notched hole cut up and down, and both ends of the shaft 22a of the upper roller 21a are inserted therebetween, and between the upper end of the notched hole and the shaft 22a of the upper roller 21a. The spring device 28 for restoring the upper roller 21a is provided. The spring device 28 has a pressure rod 281 is installed to the frame 14 so as to be able to flow up and down, and pushes the pressure rod 281 downward around the pressure rod 281 to elastically support the upper roller 21a. A spring 282 is provided. The roller installed at the top by this structure rotates while flowing up and down according to the thickness and amount of the vinyl to be drawn.

And the inlet roller 20 is rotated through a separate dedicated motor. The motor consists of a gear motor 29 capable of producing a large torque at low speed because the inlet roller 20 rotates at low speed, and is capable of forward and reverse rotation to adjust the amount of inlet. That is, since the gear motor 29 rotates at a low speed, the inertia rotational power is small, so that the forward rotation, the reverse rotation, and the stop operation can be performed instantaneously in a short time, and when the vinyl is sucked in by the primary crushing drum 30a to be described later, Since the roller 20 rotates at a constant speed, it is possible to prevent the waste vinyl from being sucked up by the brake action by the gear motor 29.

In addition, the sprocket 291 is installed at one end of the lower roller shaft (22b) is connected to the drive gear motor 29 and the chain (292) for exclusive use of the retractor roller 20 to receive power. At the opposite end of the lower roller 21a connected to the gear motor 29 as shown in FIGS. 4A and 4B, the first gear 24 and the first gear 24 are provided at the shaft end of the upper roller 21a. The second gear 25 having the same size as the first gear 24 is provided. In addition, between the first gear 24 and the second gear 25, third and fourth idler gears 26a and 26b for transmitting power are provided, and the first gear 24 and the third gear meshing with the first gear 24 and the second gear 25 are provided. The idle gear 26a and the fourth idle gear 26b meshing with the second gear 25 are connected by the first and second connecting arms 27a and 27b, respectively, to rotate while maintaining the upper mesh. At the same time, the third idler 26a and the fourth idler 26b are connected by a third connecting arm 27c which is free to rotate. Therefore, while the upper roller 21a moves up and down, the rotational force is always transmitted, and since the rotational force is reliably transmitted through the gear of the same size, the upper and lower rollers 21a and 21b always rotate at the same rotational speed.

In addition, the first and second shredding drums 30a and 30b in which a plurality of blades 35 are provided on the surface of the sorter are installed. The blade 35 is bolted to and fixed to a plurality of protrusions 34 protruding in a ring shape on the surface of the crushing drum, and the interval between the first and second crushing drums 30a and 30b is that the blades 35 cross each other. The blade 35 has a triangular plate structure and has blades 22 formed on both sides of the blade as shown in FIG. It has a bent shape, and the root portion is composed of a coupling portion 24 formed with a plurality of screw holes to fold the coupling portion 24 of the blade 35 on one side of the above-described protrusion 34 to be coupled and fixed with screws. . In this case, the blade 35 coupled to the primary shredding drum 12a is fixedly coupled to the surface opposite to the surface of the protruding portion 34 to which the blade 35 of the second shredding drum 12b is coupled.

In addition, each of the primary crushing drum (30a) and the secondary crushing drum (30b) is provided with a separate dedicated motor (31a) (31b), each pulley (32a) on one side of the primary and second crushing drum shaft (301, 302) ) 32b is formed to receive power from the motors 31a and 31b to the belt 33 and rotate in the same direction. Because of this structure, the 1st and 2nd shredding drums 30a and 30b are supplied with separate power, so even if a large resistance occurs in one shredding drum, they are not influenced by each other's operation, and even if the amount of vinyl is large enough to extinguish them. You have as much power as you can. In particular, the occurrence of the slip phenomenon of the belt 33 is significantly reduced than the conventional structure to prevent the loss of power. In addition, the primary and second crushing drums (30a, 30b) are installed close to each other, the primary crushing drum (30a) is larger than the secondary crushing drum (30b) and at the same time the primary crushing drum (30a) Faster than the speed of the inlet roller 20, the secondary shredding drum 30b rotates faster than the primary shredding drum 30a. The speed ratio of the secondary shredding drum 30b to the primary shredding drum 30a is preferably about 1.5 to 1. In addition, when the incoming waste vinyl is agglomerated, it is difficult to crush it smoothly only by the rotational force of the motor, so that the waste vinyl is shredded using the inertial force of the drum. Therefore, the weight of the pulleys (32a) and (32b) installed on the primary and secondary shredding drum shafts acts as a flywheel to maintain the rotational force.

6 is a structural diagram of a screen according to the present invention, as shown in the lower portion of the first and second shredding drums (30a, 30b) is not made of a porous body so that the foreign material such as dirt does not pass through the escape The screen 40 is provided. The screen 40 is formed by a plurality of support members 41 placed vertically, and a plurality of rods 43 penetrating the support members 41 at regular intervals. The support member 41 has a structure that is bent in an arc shape along the curved surface of each of the first and second shredding drums 30a and 30b at the lower portion of the first and second shredding drums 30a and 30b. On the side of the support member 41, a plurality of holes 42a into which the rods 43 are fitted are formed at regular intervals. The gap between the holes 42a corresponding to the lower part of the secondary shredding drum 30b is closely spaced. The hole of the screen 40 was made small. In addition to the hole 42a into which the rod 43 is fitted, the hole 42b into which the other spacing holding rod 44 is fitted is formed intermittently. When the rod 43 and the gap retaining rod 44 are inserted into the support member 41, a spacer 46 for maintaining the gap of the support member 41 is inserted, and the support member and the support are supported by the spacer 46. The gap between the members 41 is adjusted. When the rods 43 and 44 are fitted in this way, the screen 40 is assembled by screwing nuts at both ends. In addition, the rear side of the screen 40 is gently extended in the upward direction is formed with a guide portion 47 for guiding the vinyl cut by the secondary shredding drum (30b) to the next process.

In addition, the lower portion of the screen 40 is formed with a hopper-shaped guide plate 50 for collecting foreign matter (dirt) falling as shown in Figure 1, the lower portion of the guide plate 50, the discharge conveyor 52 for discharging the dirt is It is installed. Therefore, the foreign matter passing through the screen 40 is sent to the waste disposal plant by the discharge conveyor (52).

On the other hand, the waste vinyl guided by the guide portion 47 of the screen 40 is supplied to the shredder 60.

The shredder 60 has a blade 64 for shredding the waste vinyl transferred into small particles as shown in Figs. 1, 3, 7, 8, and 9, a rotation shaft 61 for rotating the blade, and a rotation shaft. The gear motor 66 which rotates 61 is comprised. The blade 64 is formed in a number of tooth-shaped blades on the outer circumference of the special steel and can be moved horizontally when coupled to the rotating shaft 61, spline processing to rotate integrally with the rotating shaft 61, carburizing heat treatment Increased wear resistance. And the spacer 62 is also splined and coupled to the rotating shaft 61, like the blade (64). In addition, a power transmission device for transmitting power from the gear motor 66 is required to rotate the rotary shaft 61. A helical gear is suitable to apply a uniform and continuous force to the gear gear when performing the crushing operation of the blade. . In addition, the helical gear is preferably heat treated in order to increase the hardness.

The blades 64 and the spacers 62 are alternately fitted to the rotary shaft 61 such that the blades 64 are arranged at regular intervals to form one rotary blade assembly 67. The rotary blade assembly 67 is installed adjacent to the blade 64 to cross the blade to form a pair with each other. At this time, in order to increase the shredding effect, a plurality of sets of rotary blade assembly 67 of such a structure may be installed laterally, or may be installed in multiple stages as well as up and down.

The rotary blade assembly 67 is rotated by each rotary shaft 61 is connected to the gear motor 66. At this time, one of the rotary blade assembly 67 of the rotary blade assembly 67 is to be rotated at a faster speed than the other rotary blade assembly. And since the blades 64 are rotated in a state in which the sides are close to each other, so that a cutting effect such as scissors is obtained, the cutting ability is excellent.

In addition, waste vinyl removal guides 70 are fixedly installed on the rotary blade assemblies 67 as shown in FIGS. 10 and 11. A plurality of waste vinyl removal guides 70 are arranged in a frame of the crusher 60 so as to correspond one-to-one to each blade 64 of the rotary blade assembly 67. The structure of the guide 70 is a blade at a position corresponding to each blade 64 of the rotary blade assembly 67 at the same time as the front surface 71 forms a curved surface, such as the radius of curvature of the spacer 62 fitted to the rotary shaft 61. A plurality of blade grooves 72 are formed through which 64 is inserted. And the bottom surface is provided with a guide surface 73 having a gentle inclination falls to the bottom by the speed at which the removed vinyl is rotated by the blade 64 or the spacer 62.

In addition, the conveying conveyor 80 is installed in the lower part of the shredder 60 to finely shred the vinyl cut by the first and second shredding drums (30a, 30b) in the shredder 60 and then moved to the regeneration process. .

Looking at the operating relationship of the present invention having such a structure as follows.

First, when the vinyl used to grow crops in the field is collected and placed on the conveyor 10, the conveyor 10 transfers the vinyl to the inlet roller 20, and the workers roughly pick up the foreign matter or dirt. Isolate. This operation prevents the blade 35 of the shredding drum from being damaged by bulky and hard foreign matter.

When the waste vinyl reaches the inlet roller 20, the inlet roller 20 rotates to introduce the waste vinyl into the inside of the sorting machine. At this time, the inlet roller 20 transmits power from the separate gear motor 29 to the lower roller 21a through the chain 292 and rotates the lower roller 21a so that the lower roller 21a is the first gear 24. ), The third and fourth idler gears 26a and 26b and the second gear 25 transmit power to the upper roller 21a. At this time, the upper roller 21a is rotated opposite to the lower roller 21a. Therefore, because the upper and lower rollers 21a and 21b rotate from the outside to the inward direction, the waste vinyl supplied therebetween is drawn in. At this time, the amount of vinyl supplied is irregular and may vary in thickness depending on the foreign matter mixed inside. If this situation is ignored and the upper and lower rollers 21a and 21b are installed in the engaged state, the waste vinyl will be caught by the inlet roller 20 and will not be transferred to the inside of the sorter. Therefore, when the amount of waste vinyl or a large amount of foreign matter passes, the upper roller 21a is raised to the upper part of the cutout hole of the frame 14 while compressing the spring 282 of the spring device 28, and then The space between the rollers 21a and 21b is widened to allow foreign materials to pass through with a large amount of waste vinyl or bulky materials. In addition, when the amount of waste vinyl passed is reduced, the waste vinyl continues to be drawn in at a constant speed since the load of the upper roller 21a and the elastic force of the spring device 28 are lowered to rotate while pressing the waste vinyl. Even if the upper roller 21a is raised in this manner, the first gear 24, the third and fourth idler gears 26a and 26b and the first to third arms 27a, 27b and 27c are raised. Since the two gears 25 remain connected, the rotational force is transmitted reliably.

In this way, the waste vinyl supplied by the inlet roller 20 is transferred to the inside of the sorting machine at a constant speed. The conveyed vinyl is shredded as the blade 35 mounted on the outer circumferential surface while the primary crushing drum 30a rotates. That is, the inlet roller 20 supplies the vinyl at almost the same speed, and the primary crushing drum 30a rotates faster than the conveying speed of the vinyl. Therefore, the supplied vinyl is cut by cutting down the waste vinyl which is entered while the blade 35 of the primary shredding drum 30a rotates. At this time, the blade 35 is attracted to the waste vinyl, which enters the rotational force to the primary shredding drum (30a) while hitting the waste vinyl, while pressing the waste vinyl by the weight of the upper roller (21a) and the spring device 28 Since the waste vinyl is bitten by the frictional force of the urethane 23 coated on the surface of the inlet roller 20, the waste vinyl is not attracted to the primary crushing drum 30a and is maintained at a constant speed by the inlet roller 20. Will be entered.

In addition, the cut vinyl is conveyed toward the secondary crushing drum 30b by the rotational force of the blade 35. And when the incoming vinyl is crushed by the blade 35, foreign matters such as soil or stones mixed in the vinyl are cut down by gravity as the vinyl is cut.

In addition, the vinyl cut by the primary shredding drum 30a and conveyed by the centrifugal force of the blade 35 is again cut by the second shredding drum 30b. That is, the secondary shredding drum 30b rotates in the same direction but the primary shredding drum 30a rotates in the same direction, but the primary shredding drum 30a rotates in the upward direction when viewed from a position where the blades 35 intersect. The drum 30b rotates downward. For this reason, the vinyl conveyed by the centrifugal force of the primary shredding drum 30a and the blade 35 again crosses the blade 35 of the secondary shredding drum 30b, and the blade 35 of the secondary shredding drum 30b. The vinyl is intercepted and cut second.

In addition, the waste vinyl shredded by the secondary shredding drum 30b is transferred to the next process by centrifugal force, and some of the waste vinyl is wound on the second shredding drum 30b and rotated.

If the quality of waste vinyl is different or the shredding particles of waste vinyl need to be controlled, the desired work efficiency can be achieved by adjusting the rotation speed of the primary and secondary shredding drums by replacing the pulleys installed at one end of the primary and secondary shredding drum shafts. Can be obtained.

On the other hand, when the first and second shredding drums 30a and 30b shred waste vinyl, the shredding efficiency varies depending on the structure of the blade 35 installed in the shredding drum. In particular, since the blade 35 of the present invention is formed in a jagged wave form, not only the cross-sectional area in contact with the waste vinyl increases, but also the waste vinyl is cut into a saw shape. Therefore, the waste vinyl can be cut more effectively. In addition, the blades 35 of the primary crushing drum 30a and the secondary crushing drum 30b use the blades 35 in the same direction. The continuous use of such a blade (35) should be replaced as the blade wears out and becomes dull. But the blade on the opposite side of the dull blade is like a new blade because it is not used at all. Since the blade 35 installed on the primary shredding drum 30a and the blade 35 installed on the second shredding drum 30b are installed in opposite directions, the blade 35 is used interchangeably as shown in FIG. 5B. Can be used without replacement.

The vinyl cut by the secondary shredding drum 30b as described above is guided by the screen guide 47 by the centrifugal force of the second shredding drum 30b and then transferred to the shredder 60. When conveyed, it is filtered by the screen 40 installed at the bottom and then conveyed along the guide 47 of the screen 40. On the other hand, the foreign matter (dirt) that is separated by the primary crushing drum (30a) and the secondary crushing drum (30b) falling by gravity passes through the network to the upper portion of the discharge conveyor 52 through the hopper-shaped guide plate 50 Will fall. The discharge conveyor 52 transfers the fallen foreign matter to the waste disposal plant.

Meanwhile, the first and second shredded vinyls transferred to the shredder 60 are shredded into fine particles while passing through the shredder 60, and the shredded vinyl particles are bound by distance, height and environment by the transfer conveyor 80. It is transferred to the next process without receiving. However, depending on the conditions, other conveying devices may be used instead of the conveying conveyor.

In addition, when the rotary blade assembly 67 cuts the waste vinyl supplied to the shredder 60, the waste vinyl is wound around the blade 64 or the spacer 62 to rotate together. In this case, the waste vinyl separation guide 70 Since it effectively removes the vinyl, the shredding effect of vinyl is increased.

In addition, the sorting device of the present invention is provided with a safety device. This safety device is achieved by providing a limit switch 37 on the drum cover 36. That is, a pair of the primary and secondary shredding drums (30a, 30b) is rotated at high speed by the high-speed motor (31a) (31b) with a plurality of sharp blades 35 installed on the outer peripheral surface, during use or after stopping When the drum cover 36 is opened due to the inspection of the crushing drums 30a and 30b and the replacement of the blade 36, the limit switch 37 is operated so that all operations of the sorter are stopped by this switch. It was. By this structure, the primary and secondary shredding drums 30a and 30b are always operated only when the cover 36 is closed, thereby protecting the worker from the sorter.

As described above, the present invention is rotated at the same rotational speed even if the inlet roller is driven by the chain from the drive motor and the upper roller is driven by the gear means from the lower roller, so that the amount of vinyl passed through is high. Since waste vinyl is always supplied constantly by the load of the upper roller and the frictional force of the urethane coated on the surface of the spring device and the retracting roller, the shredding effect is increased when shredded by the primary shredding drum.

In addition, as the waste vinyl gradually passes through the primary crushing drum, the secondary crushing drum, and the crusher gradually to finely crush, the crushing efficiency is further improved, and the screen is shredded in the primary crushing drum and the secondary crushing drum. According to the size of the waste vinyl, the screen consists of two parts with different sizes of holes, effectively separating the waste vinyl from foreign substances, thereby improving the sorting function of the sorter.

Also, as the blades of the primary shredding drum and the secondary shredding drum cross each other, the vinyl wound around the primary shredding drum is intercepted and transported while cutting the blade of the second shredding drum, so that the vinyl is wound around the primary shredding drum. As it is prevented, not only the function of the sorter is improved, but also the work efficiency is increased because there is no troublesome work to stop the sorter and remove the waste vinyl to remove the waste vinyl wound as in the prior art.

In addition, as the inlet roller and the first and second crushing drums are driven as separate dedicated motors, even if a large load is applied, the inlet roller and the first and second crushing drums can be sufficiently extinguished without power loss caused by the slip phenomenon as in the prior art. When adjusting, there is no reverse rotation of each of the shredding drum at the same time as in the prior art can be easily and conveniently adjusted the speed.

In addition, since the screen is assembled, it is easy to manufacture, partial replacement is possible in case of damage, and the size of the screen can be adjusted, thereby reducing costs.

In addition, as the waste vinyl is shredded finely by the shredder, the recycling efficiency of the waste vinyl is increased.
