Description

Cutting machine of perforation machine {CUTTER OF HOLE CUTTING MACHINE}

The present invention relates to a cutting machine of an air hole, and more particularly, in forming seed germination holes in the plastic paper, the plastic paper is temporarily sucked into the cutting machine at the time of setting before the drilling, and is set by the rotating body after cutting. The present invention relates to a cutting machine of an air perforator which can smoothly pierce a plastic sheet by eliminating the phenomenon in which the cutting is automatically lowered by the wind and sticks to the cutting machine side.

Generally, the pore means a machine for forming a hole for seeding into a vinyl to germinate seeds of a crop. This air hole process is one of the processes in which vinyl is produced, which is installed in a vinyl production line and classified as one of a series of vinyl production processes.

1 is an explanatory diagram schematically showing a general vinyl production process including a pore process.

In this figure, reference numeral 10 denotes a vinyl making machine, 20 denotes an air hole, and 30 denotes a winding machine for winding the produced vinyl film in roll form. In the vinyl maker 10, vinyl in a raw state is made of vinyl in a film form, and is transferred to the air hole 20 through a plurality of idle rollers 12, and in the air hole 20, the film is formed at an appropriate interval and diameter. After forming a plurality of holes in the plastic paper (X) of the shape and then wound in a roll (roll) form in the winder (30) of the next step is sold after the packaging process.

The perforator 20 has a plurality of crossbars 21 are arranged in a radial shape of a circle and the cutting machine 23 including a plurality of motors (M) is installed on the crossbars 21 on the plastic paper (X) The punched-in plastic paper X is wound so that it may be wound by the winding machine 30 through many idle rollers 22 and 32 also.

The cutting machine 23 has a circular rotating body 23a which rotates in response to the rotation of the motor M, and includes a bracket 26 which supports the motor M and the rotating body 23a. do. The rotating body 23a forms a plurality of fixing holes 23b to fix the blade 24, and the fixing holes 23b form different radii from the center of the rotating body 23a, respectively. The sizes of the holes X 'and X' 'formed in the plastic paper X are adjustable.

As shown in FIGS. 5 and 8, the bracket 26 is fixed on the crossbar 21 by catching the fixing clip 40 on the fixing piece 26a protruding from the edge (FIG. 6). Reference). The fixing clip 40 is formed on both ends of the resilient wire 42 by the engaging projection 44 having a triangular cross section to be caught by the locking groove 21a of the crosspiece 21.

Next, an operation of forming holes X 'and X' 'in the plastic paper X will be described.

As shown in FIG. 2, the plastic paper X approaches the cutter 23 in the direction of the arrow to drill holes X ′ and X ″. That is, the crosspiece 21 disposed in a cylindrical shape in the air hole 20 rotates at a predetermined rotational speed, and the blade 24 of the cutter 23 rotates at a high speed. Subsequently, the plastic paper X is transferred onto the cutting machine 23, and the plastic paper X contacts the ends of the central axis 25 to hold the centers of the holes X ′ and X ″ to be drilled. The instantaneous blade 24 is in contact with the plastic paper (X) to form a hole (X '), (X' ') instantaneously.

In addition, for general information about the air hole 20 or the basic process of drilling holes, see Utility Model Publication No. 90-10414 (Nov. 17, 1990).

However, the conventional air hole 20 has the following problem.

1. Referring to FIG. 2, when the plastic paper X approaches the cutting machine 23 which rotates at high speed, the bracket 26 is not formed so that no air passage hole is formed. As a result, an air pressure difference occurs between the upper side A and the lower side B. FIG. That is, the low pressure is always formed in the vicinity of the central axis 25 by the rotating body 23a rotating at a high speed rotation of the motor M, and wind is formed in the radial direction of the rotating body 23a.

At this time, the plastic paper (X) approaching is sucked into the side where the low pressure is formed (center shaft 25 side), and in this state, when the cutting operation is performed by the blade 24 momentarily, the remaining round vinyl is cut. The cut is stuck to the central axis 25.

This phenomenon is fatal for the perforator 20, which continues to perform the cutting process. As the cut generated in the previous hole-making operation stays on the central axis 25, it hinders the subsequent drilling operation. As well as deteriorating the accuracy of subsequent drilling operations.

In addition, as the cutouts stagnate near the central axis 25, the motor M is overloaded, and there is a problem of component burnout, and the work must be frequently stopped to remove the cuts from the central axis 25. It is pointed out as a cause of productivity deterioration because the punching process cannot be made.

On the other hand, the thin cut material is stuck to the plastic paper (X) is completed by the electrostatic phenomenon is mixed and wound between the plastic paper (X) of the finished product in the winding step of the winding machine 30, which is a subsequent step. .

This mixing phenomenon, when the product is sold in the future to be used in the actual crops will be thrown on the ground or swayed in the wind, causing environmental pollution, and users will be very inconvenient when working on the crops.

The present invention has been devised to solve this problem in view of the above-mentioned conventional problems, and in forming the seed germination hole in the plastic paper, the plastic paper is temporarily sucked into the cutter side at the time of setting before the punching to be set, and after cutting It is to provide a cutting machine of the air perforator that can be punched in the plastic paper smoothly by eliminating the phenomenon that the cutting is automatically stuck downward by the wind generated by the whole to stick to the cutter side.

First, the schematic structure of the cutting machine 23 of the present invention will be described with reference to FIG. 3, while the circular rotating body 23a is embedded in the cover body 50 from the upper side and centered on the motor M output shaft at the bottom. It is fixed through the shaft 25. The cover body 50 surrounding the rotating body 23a and the brackets 26 thereunder are fixed to the motor main body separately from the rotating body 23a so that the rotational force of the motor M is transmitted only to the rotating body 23a. have.

Referring to Figs. 3 and 7, the rotor 23a will be described. The rotor 23a has a circular shape and is framed by a cross rib 23c therein. A plurality of fastening grooves 23b are formed at different radii from the central axis 25 so that the blades 24 can be fastened, and a space 23d is formed between the ribs 23c.

Referring to the cover body 50 of the present invention with reference to Figures 3 and 9, the cover body 50 is formed with an outer wall 52 for embedding the rotating body 23a and a plurality of air holes ( 54) formed underside. The flat bottom surface is provided with a hole for passing through the central axis 25 and a fixing hole 55 for fixing the cover body 50 to the bracket 26.

Referring to the brackets 26 of the present invention with reference to Figures 3 and 8, the brackets 26 is formed of four fixed to secure the fixing clip 40 in the vicinity of the corner of the overall shape is approximately square. A piece 26a is formed, and a plurality of air holes 26b for air flow corresponding to the air holes 54 of the rotating body 23a are formed, and a central hole for receiving the central axis 25 in the center portion ( 26c) and a fixing hole corresponding to the fixing hole 55 of the cover body 50 are formed.

It is formed by forming the locking projection 44 to be caught by the piece 26a.

The cutting machine 23 of the air hole according to the present invention having such a configuration forms holes X 'and X' 'in the plastic paper X during the manufacturing process as shown in FIG. When the air hole 20 rotates in the direction of the arrow, the plastic paper X is supplied onto the cutting machine 23, and the cutting machine 23 is supplied with the plastic paper X as shown by a large arrow in FIG. The rotating body 23a is rotated at a high speed in one direction by the motor M as indicated by an arrow indicating rotation.

At this time, air flow is formed around the cutting machine 23 by the rotating body 23a and the cover body 50 (see each arrow in FIG. 2). That is, a downward airflow is generated by the air introduced through the space 23d of the rotating body 23a around the central axis 25, and the rotating body between the rotating body 23a and the cover body 50. Ascending airflow is generated by the air introduced through the air hole 54 in the 23a and the air hole 26b in the cover 50.

The vinyl cut does not stick to the central axis 25.

This separation phenomenon is such that the circular cuts do not stick to the air hole 20 which is continuously being cut, so that the hole does not stay in the air hole 20, that is, the central axis 25, even when the hole cutting operation is continued. As a result, subsequent perforations work very smoothly, improving the accuracy of subsequent perforations.

In addition, the present invention adopts a fixed hole 40 of the shape as shown in Figures 4 and 6 in order to solve the problems appearing in the conventional fixed clip (40) as shown in FIG. The cutting machine 23 of the present invention is to be detached very quickly.

In more detail with respect to the fixed clip 40 of the present invention, the inside of the fixed clip 40 is formed by integrally forming the elastic piece 46 of the metal piece rich in elasticity and forming the locking projections 44 at both ends. Therefore, as shown in FIG. 6, the insertion strength is superior to that of the conventional fixed clip while being made very smoothly in inserting and mounting the triangular locking protrusion 44 into the locking groove 21a of the crosspiece 21, and the blade is excellent. (24) Even when the cutting machine 23 of the present invention is removed from the crosspiece 21 in the necessity of changing the size of the hole X 'or (X' ') or the like again, the fixing clip 40 It is very convenient to achieve the purpose just by simply cutting the.
