Description

Shredder for waste synthetic resin film

The present invention relates to a waste synthetic resin film shredder that can effectively remove foreign substances on the surface while cutting the recycled synthetic resin film to increase the value as a recycled material.

Agricultural waste synthetic resin films collected from vinyl houses, mulching media, etc., and waste synthetic resin films collected after being used for general merchandise packaging have a recycling value. In order to recycle this kind of waste plastic film, it is necessary to go through the cutting process, which is the preliminary stage of pelletization, and to remove foreign substances such as dirt and dust on the surface.

Most of the waste synthetic film collected in the vinyl house and mulching media is long-lasting. Long life waste synthetic resin film is not easily picked up for easy handling, but it is common practice to walk and discard it as a bundle, and the waste synthetic resin film collected in this state is not easy to be shredded and removes dirt and foreign matter from the surface. It is not formidable either. This makes it difficult to recycle the raw materials of agricultural waste synthetic resin film.

Until now, waste plastic film fragments are dependent on hand scissors and are always exposed to the risk of hand injury, and the removal of soil and foreign substances is also manpower dependent. Overall, the process of recycling waste plastic film is inefficient, inefficient, and dusty. It also causes problems that harm the health of the worker and the environment in the workplace.

It is practically very difficult to remove foreign substances by washing with water one by one. Water supply and labor costs are too high, and it is not unreasonable to unfold and wash the agglomerated waste plastic film masses one by one.

In addition, the cutting of the waste synthetic resin film by hand may impede pelletization due to the uneven specification of the cut products.

Therefore, the object of the present invention is to efficiently perform the cutting operation and the removal of foreign matters on the surface, which are the previous steps for pelletizing the agricultural waste synthetic resin film that can be recycled, and the waste synthetic resin film fragments to facilitate pelletization. It is to provide a thinner for waste synthetic resin film that can be uniform in size.

.

The problem to be implemented in the present invention is to cut a waste synthetic resin film into a narrow strip shape by installing a cutting part formed of a cutter having circular blades and a supporting roll corresponding to the cutter at regular intervals on a rotating shaft at the tip of the base. On the back of the cutting part, a vibrating roll vibrates by the oscillation means such as pneumatic or cam, and installs a foreign material removal part to drop foreign materials, and then vibrates to the surface of the waste synthetic resin film cut after being cut into a belt and buried on the surface. To remove foreign substances such as dirt and dust, and to make constant winding of the waste plastic resin film which is pulled into the cut waste plastic film fragment on the rear base of the foreign material removal unit and to the regular winding of the cut waste plastic film fragment. Fixed width cutting and washing of waste synthetic resin film It can be achieved with a thinner for waste synthetic resin film which can be configured to handle the removal of foreign matter after cutting.

A series of operations are carried out by cutting agricultural waste synthetic resin films that are collected randomly with a lot of foreign substances such as soil, dust, and straw into strips of a certain width, removing foreign substances on the surface of the cut waste synthetic resin film, and winding them on the winding part. It is very efficient because it is carried out collectively in one machine, and the size of waste plastic film to be cut is uniform, so it is easy to be pelletized in later work, and foreign matters on the surface of waste plastic film are removed mechanically after cutting, thus removing Is very efficient and does not require personnel to remove debris, so there is no concern for health.

In FIG. 1, the thinner for waste synthetic resin film proposed by the present invention is composed of a base 10, a cutting unit 20, a foreign material removing unit 30, and a pulling unit 40.

The base 10 supports the foreign material removing unit 30 and the pulling unit 40, including the cutting unit 20, and is a balanced frame that can be commonly seen.

The cutting part 20 cuts the waste synthetic resin film injected from the front end side of the base 10 in a continuous width, and is composed of a cutter 21, a motor 22, a blade 23, and a support roll 24. do.

Referring to FIG. 2, the cutter 21 cuts the waste synthetic resin film introduced under the rotary blade 21b installed at a predetermined interval on a single rotary shaft 21a at intervals of the rotary blade 21b. It is provided on the blade 23 which stood at the front-end | tip of (10).

The motor 22 is a driving means for rotating the cutter 21 by connecting a drive pulley mounted on the motor shaft and a driven pulley mounted on the motor end portion of the rotary shaft 21a with a belt, and mounted on the base 10. It also serves as a driving means for the pull portion (40).

The blade 23 is installed across the tip of the base 10 to support the cutter 21.

The waste synthetic resin film to be inserted into the cutting unit 20 is not uniform in thickness, such as a part of a plurality of layers and a part of the sheet. In order to effectively cut such waste synthetic resin film, it is more advantageous to allow the cutter 21 to be more flexible by changing the height of the cutter 21 than the supporting roll 24 having a fixed position on the base 10 according to the thickness of the waste synthetic resin film. Do.

In consideration of this point, the rod-shaped guide rod 25 is attached to the apex of the bearing rotatably supporting both ends of the rotating shaft 21a of the cutter 21 so that the upper blade 23 of the cutter is horizontally attached. The support plate 26a, 26b is penetrated in the longitudinal direction, and a collar 27 is attached on the guide rod 25 between the upper and lower support plates 26a, 26b and a spring is provided between the collar 27 and the upper support plate 26b. The cutter 21 can be effectively cut up and down elastically according to the thickness of the waste synthetic resin film loaded by loading (28).

In order to enable such a lifting operation of the cutter 21, the shaft hole 29 drilled in one post is drilled in the longitudinal hole type considering the lifting width of the cutter 21.

The foreign material removal unit 30 is to drop the foreign matter that is buried in the cut waste plastic film passing through the vibrating roll 32 is vibrated by the oscillation means 31, the oscillation means 31 in the drawing is pneumatic It is illustrated in the form of a tank, which is easy to vibrate by pneumatic pressure periodically supplied by placing the shaft of the vibrating roll 32 on the elastic body 35 fitted in the longitudinal hole 34 of the bearing 33. The oscillation means 31 of the vibrating roll 32 may be replaced by a cam driving method.

Pulling portion 40 is to pull the long waste synthetic resin film cut out in a narrow width to the cutting speed to facilitate winding to the winding portion 50, the upper driven side pull roll 41 and the lower driving side pull The rolls 42 are coupled to each other to rotate and pull out the waste synthetic resin film cut therebetween. The power of the drive side pull roll 42 is obtained from the motor 22.

In FIG. 1 again, the waste synthetic resin to be cut between the cutter 21 and the support roll 24 in front of the base 10 when the cutter 21, the vibrating roll 32, and the upper and lower pull rolls 41 and 42 are in operation. The tip of the film (a) is pushed in. The waste synthetic resin film (a) is as it has been collected. That is, the foreign matter is not removed, and the aggregates are united together, and the sheet refers to the single sheet.

The waste synthetic resin film (a) is squeezed between the cutter 21 and the support roll 24 to be cut in a predetermined width by the cutter 21 while being moved in the advancing direction.

The waste synthetic resin film fragment (b) is passed through the vibrating rolls 32 of the foreign material removing unit 30 and then bites between the pulling rolls 41 and 42. In these processes, foreign matter buried on the surface of the waste plastic film fragment (b) is pulled at a constant speed while being dropped by the violent movement of the vibrating roll 32.

The waste synthetic resin film fragment (b) exiting the pull section 40 is wound on a typical roll winding unit 50.

Since the waste synthetic resin film is cut to a certain width, it is possible to homogenize pelletization in a subsequent process. In addition, it was difficult to drop off materials such as soil and dust due to the factors such as wideness and agglomeration. It is possible to remove foreign substances easily and hygienically and safely and efficiently by the method of cutting and vibration of the waste resin film. .
