Description

PVC floor tile cutting equipment {PVC floor tile cutting equipment}

The present invention relates to a PVC floor tile cutting device that allows easy and continuous cutting of PVC floor tiles.

In general, a floor tile cutter inserts a pad for floor tiles between the upper and lower die and the punch, and then cuts them by the lifting and lowering action of the punch, or lowers a single blade like a shear device to cut it, and then raises it again. It is used to cut through a structure in which the task is repeated, and to make cutting possible by continuously feeding and feeding the pad.

The cutting knives used in these floor tile cutting machines are made of a material that has excellent wear resistance and is not easily worn or damaged, preventing frequent replacement and ensuring that the products being cut are precisely cut.

However, in the case of these floor tile cutters, most of them had a structure that cut the floor tiles when lowering and then returned to the top, which reduced cutting speed and work efficiency.

The PVC floor tile cutting device according to the present invention includes an installation stand (10), a connecting member (20), a moving cutter (30), a guide part (40), a fixed cutter (50), and a supply roller part (60).

The installation stand 10 is installed at one end of the cylinder unit 11 and moves forward and backward horizontally along the LM guide 12.

That is, the LM guide 12 is installed horizontally at the top of the holder 100, and the cylinder part 11 is installed outside the top of the holder 100 so that the piston can be discharged horizontally at the bottom of the LM guide 12. do.

Accordingly, the upper end of the installation stand 10 is installed on the LM guide 12 so as to be movable left and right, and one side (left side) is connected to the piston of the cylinder part 11, so that the cylinder part 11 is compressed/moved. It has a structure that moves left and right along the LM guide (12) when discharging, and has the shape of a square plate.

The connecting member 20 is a link member whose one end is connected to the lower end of the installation stand 10. The upper end (one end) is rotatably connected to the lower end of the installation stand 10, and the lower end (the other end) is connected to the lower end of the installation stand 10. is rotatably connected and installed at the top of the mobile cutter 30, which will be described later.

Two of these connecting members 20 are installed between the installation stand 10 and the mobile cutter 30 so that they are spaced apart from each other and perform the same operation at the same time, but the number can be varied depending on the user's embodiment.

The movable cutter 30 has the other end of the above-described connecting member 20 linked at the upper end, and at the lowermost end, an upper cutting blade 31 forming first and second cutting blades 32 and 33 at the upper and lower ends. This is a part formed by a diagonal line at a diagonal setting angle toward the longitudinal direction.

In the present invention, the upper cutting blade 31 has a structure in which the upper cutting blade 31 gradually lowers as it descends and is installed at an angle from left to right, so that the fixed cutting blade 51, which will be described later (shearing device), is similar to the cutting method of scissors. Cutting begins from the right side of the upper cutting blade 31, which is in contact first, and proceeds toward the left side.

In addition, this movable cutter 30 is installed on one side of a plurality of pressing parts 70 spaced apart from each other, and by descending together with the movable cutter 30, the movable cutter 30 cuts the PVC floor tile (T). When cutting, the PVC floor tile (T) adjacent to the cutting position is compressed by the elastic member 72 to fix the position.

Looking at the configuration of the pressing part 70 for this, a fixing table 71 installed on one side of the mobile cutter 30, an elastic member installed perpendicular to the fixing table 71 and wound to be tensionable/compressible ( 72) (ex: spring, etc.) and a cushion member 73 that serves as a cushion and is located at the bottom of the elastic member 72.

In addition, the upper cutting blade 31 has a first recessed portion 34 where the first and second cutting blades 32 and 33 do not contact the fixed cutting blade 51, and the first and second cutting blades 32 , 33), the contact area with the fixed cutting blade 51 can be reduced to reduce wear and increase cutting efficiency.

Accordingly, in the initial state in which the cylinder portion 11 is compressed, the upper end (a) of the link connected to the installation table 10 is positioned at the rear end than the lower end (b) of the link connected to the movable cutter 30. When the piston of the cylinder unit 11 is discharged and the upper and lower ends (a, b) of the link become vertical, the movable cutter 30 is lowered while contacting the fixed cutter 50 to perform the first cutting. After going through the first cutting step, the piston of the cylinder unit 11 is discharged relatively more than the first cutting step, so that the upper end (a) of the link is located at the front than the lower end (b) of the link, The mobile cutter 30 is in contact with the fixed cutter 50 to have a second cutting step in which secondary cutting is performed, and the PVC floor tile (T) that moves in one direction between the mobile cutter 30 is formed. This is so that the movable cutter 30 can be cut continuously twice when descending and rising when it comes into contact with the fixed cutter 50.

In the present invention, the movable cutter 30 repeats lowering and lowering once until the piston is completely discharged to perform two cuts, so even when the piston is compressed and returned to its original state, the movable cutter 30 lowers and lifts again. It would be natural for the cutting process to be carried out twice while repeating.

The guide portion 40 is installed on both sides of the above-described movable cutter 30 and guides the movable cutter 30 so that it can only be raised and lowered vertically.

This guide portion 40 is made of a plurality of rollers, and is installed on the holder 100 on the front and rear sides of the movable cutter 30 so as to rotatably correspond to the movable cutter 30, so that the movable cutter 30 It can be configured to allow ascending and descending only vertically.

Of course, if the guide part 40 is made of a plurality of rollers, both sides of the moving cutter 30 may also be made of a shape corresponding to these rollers.

The fixed cutter 50 is spaced apart from the lower end of the above-described movable cutter 30 and is fixedly installed on the holder 100, and the fixed cutting blade 51 on one side contacts the upper cutting blade 31 in the longitudinal direction. It is the part that is formed horizontally with the ground.

In addition, the fixed cutting blade 51 has a second recessed portion 52 that is depressed in the longitudinal direction at the middle of one surface, and one surface that is in contact with the ascending and descending upper cutting blade 31 and the first, By reducing the contact area of the second cutting blades (32, 33), wear of the first and second cutting blades (32, 33) can be reduced and cutting efficiency can be increased.

The supply roller unit 60 is a roller installed at the front of the movable cutter 30 and provides PVC floor tiles (T) between the movable cutter 30 and the fixed cutter 50.

The supply roller unit 60 for this purpose is provided by a first roller unit 62 rotatably installed at the front end of the fixed cutter 50, and a raising and lowering cylinder unit 61 at the top of the first roller unit 62. It is installed to be able to go up and down, and when transporting the PVC floor tile (T), it is lowered to correspond to the first roller unit 62, and the PVC floor tile (T) located between the first roller unit 62 is moved. It consists of a second roller unit (63) that transports the PVC floor tile (T) to the cutting position, so that the second roller unit (63) is lowered only on the PVC floor tile (T) and moves the PVC floor tile (T) placed on the first roller unit (62). This means that it can be carried out in one direction.

In addition, the supply roller unit 60 has an encoder installed on the motor shaft of the rotating second roller unit 63, so that the supplied PVC floor tiles (T) are continuously cut to a preset length. The length of (T) can be adjusted.
