Description

Technical Field

[0001] The utility model relates to the technical field of hollow plate cutting machinery, in particular to a hollow plate cutting device with a positioning structure. Background Art

[0002] Hollow board (also called hollow grid board, Wantong board, corrugated board, double wall board) is called pp plate sheet in English. It is a new material with light weight (hollow structure), non-toxic, pollution-free, waterproof, shockproof, anti-aging, corrosion-resistant and rich colors. Compared with cardboard structure products, hollow board has the advantages of moisture resistance and corrosion resistance. Compared with injection molding products, hollow board has the advantages of shock resistance, flexible structure design, and no need to open injection molds. At the same time, the board can flexibly add anti-static and conductive masterbatch through the control of raw materials to produce plastic hollow board with conductive and anti-static functions. The surface resistivity of anti-static board can be controlled between 106~1011. The surface resistivity of conductive board can be controlled between 103~105.

[0003] Hollow board is mainly used in electronics, packaging, machinery, light industry, postal service, food, medicine, pesticide, home appliances, advertising, decoration, cultural supplies, optical and magnetic technology, bioengineering, medicine and health, etc. It is a new type of environmentally friendly packaging material.

[0004] After the hollow board is produced, it needs to be cut. The existing cutting device needs to abut and position the two sides of the board when cutting the board to prevent the cutting from being offset. However, when abutting and positioning, the board is easily squeezed by the material and causes bulging in the center of the board. Because the center of the traditional cutting device lacks a corresponding downward pressure structure to limit and prevent bulging, bulging during cutting may cause cutting offset and affect the cutting; at the same time, the cutting device abuts the hollow board on both sides to limit it to prevent displacement, but the friction with the board is large during cutting, and generally the operator needs to use a large force to push the board forward for cutting. The large force will cause the board to deform slightly. Therefore, when the friction is large, it is not convenient for the operator to push the board forward smoothly for cutting, and it is also easy to cause cutting deviation.

[0005] To this end, we propose a hollow plate cutting device with a positioning structure to solve the above-mentioned problems Utility Model Content

[0006] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a hollow plate cutting device with a positioning structure.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A hollow plate cutting device with a positioning structure is designed, comprising a cutting table, a first electric cylinder, a second electric cylinder and a third electric cylinder. An installation cavity is opened inside the front of the cutting table, a U-shaped mounting plate is welded to the upper end surface of the cutting table, the first electric cylinder is symmetrically mounted on the vertical surfaces at both ends of the U-shaped mounting plate by bolts, and the second electric cylinder is symmetrically fixedly connected to the center position of the upper end surface of the U-shaped mounting plate by bolts.

[0009] Furthermore, a U-shaped pressing block is fixed to the telescopic end of the second electric cylinder by bolts, and a pressing roller is installed on the inner symmetrical rotating shaft of the U-shaped pressing block.

[0010] Furthermore, the telescopic end of the first electric cylinder is connected to a side clamping plate via bolts, and the lower end surface of the side clamping plate is slidably connected to the cutting operating table.

[0011] Furthermore, the abutting surface between the side clamping plate and the hollow plate is provided with a mounting groove, and the inner symmetrical rotating axis of the mounting groove is connected with a side abutting roller.

[0012] Furthermore, the side abutment rollers are connected with rubber limiting belts.

[0013] Furthermore, a third electric cylinder is fixed by bolts at the center position of the inner side of the mounting cavity, the telescopic end of the third electric cylinder is connected to the left side of the lower end surface of the square mounting plate by bolts, a cutting motor is fixed by bolts on the upper end surface of the square mounting plate, and a circular cutter is installed on the rotating shaft of the cutting motor.

[0014] Furthermore, a cutting reserved opening is provided on the surface of the cutting operating table at the top end of the installation cavity, and the position of the cutting reserved opening corresponds to the circular cutter.

[0015] The utility model proposes a hollow plate cutting device with a positioning structure, the beneficial effect of which is that the first electric cylinder is extended to drive the rubber limiting belt to abut against the side of the hollow plate and the second electric cylinder is extended to drive the lower pressure roller to abut against the two sides of the cutting point of the hollow plate, so that the center bulging affecting the cutting can be avoided during cutting. At the same time, when the hollow plate is pushed, the rubber limiting belt is rotated along the installation groove through the side abutment roller and the lower pressure roller rolls on the surface of the hollow plate, thereby reducing the friction between the side clamping plate and the side of the hollow plate and the U-shaped lower pressure block and the upper end surface of the hollow plate, which facilitates smooth pushing for cutting.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-6 A hollow plate cutting device with a positioning structure comprises a cutting operation table 1, a first electric cylinder 2, a second electric cylinder 3 and a third electric cylinder 4. An installation cavity 11 is opened inside the front of the cutting operation table 1. The installation cavity 11 is used to install the third electric cylinder 4, a square mounting plate 41 and a cutting motor 42. At the same time, the installation cavity 11 can also be used to store some equipment maintenance supplies. A U-shaped mounting plate 13 is welded on the upper end surface of the cutting operation table 1. The U-shaped mounting plate 13 is made of metal and has a U-shaped structure. The vertical surfaces at both ends of the U-shaped mounting plate 13 are symmetrically mounted with the first electric cylinder 2 by bolts. The number of the first electric cylinders 2 is 2. The center position of the upper end surface of the U-shaped mounting plate 13 is symmetrically fixed with the second electric cylinder 3 by bolts. The number of the second electric cylinders 3 is 2.

[0025] The U-shaped pressing block 31 is fixed to the telescopic end of the second electric cylinder 3 by bolts. The U-shaped pressing block 31 is made of metal and has a U-shaped structure. The U-shaped pressing block 31 is located on both sides of the upper end of the cutting reserved opening 12, and the inner side symmetrical rotating shaft of the U-shaped pressing block 31 is installed with pressing rollers 32. In the present application, the number of pressing rollers 32 inside the U-shaped pressing block 31 is 2, which can be increased or decreased accordingly in actual production as needed. When in use, the U-shaped pressing block 31 is extended by the second electric cylinder 3 to drive the U-shaped pressing block 31 to move downward. When the U-shaped pressing block 31 moves downward, it abuts against the surface of the hollow plate through the pressing roller 32, which can abut against it downward so that it is close to the surface of the cutting operating table 1 to prevent bulging at the center cutting position. At the same time, the pressing roller 32 is rotatably connected to the inner side of the U-shaped pressing block 31 and can rotate along the U-shaped pressing block 31. When pushing the hollow plate, the pressing roller 32 rolls on the surface of the hollow plate to reduce friction.

[0026] Furthermore, the telescopic end of the first electric cylinder 2 is connected to the side clamping plate 21 by bolts, and the lower end surface of the side clamping plate 21 is slidably connected to the cutting table 1. The extension of the first electric cylinder 2 drives the side clamping plate 21 to move inward along the surface of the cutting table 1 to abut against the hollow plate.

[0027] Furthermore, the side clamping plate 21 and the abutting surface of the hollow plate are provided with a mounting groove 22, and the side clamping plate 21 can be changed in size accordingly as needed. The inner symmetrical rotating shaft of the mounting groove 22 is connected with a side abutting roller 23. In the present application, the number of the side abutting rollers 23 located inside the mounting groove 22 is 4, and the size and quantity of the mounting groove 22 and its inner side abutting rollers 23 can be increased or decreased according to the actual needs of the length of the side clamping plate 21. When the side clamping plate 21 moves inward, the side abutting rollers 23 abut against the two sides of the hollow plate through the rubber limiting belt 24. Because the side abutting rollers 23 are rotatably installed on the inner side of the mounting groove 22 and can rotate along the mounting groove 22, when the hollow plate is pushed to move along the surface of the cutting operation table 1, the side abutting rollers 23 will rotate along the mounting groove 22, thereby reducing the friction between the side clamping plate 21 and facilitating the smooth pushing of the hollow plate along the surface of the cutting operation table 1.

[0028] In more detail, the side abutment rollers 23 are connected with rubber limiting belts 24 , and the rubber limiting belts 24 abut against two sides of the hollow plate when the side clamping plates 21 move inwards.

[0029] In general, a third electric cylinder 4 is fixed by bolts at the center position inside the mounting cavity 11. The extension and retraction of the third electric cylinder 4 can drive the square mounting plate 41, the cutting motor 42 and the circular cutter 43 to move up and down. The extension end of the third electric cylinder 4 is connected to the left side of the lower end surface of the square mounting plate 41 by bolts. The cutting motor 42 is fixed to the upper end surface of the square mounting plate 41 by bolts. A circular cutter 43 is installed on the rotating shaft of the cutting motor 42. When the cutting motor 42 rotates, the circular cutter 43 rotates to cut the hollow plate.

[0030] Finally, a cutting reserved opening 12 is provided on the surface of the cutting operating table 1 at the top of the installation cavity 11, and the position of the cutting reserved opening 12 corresponds to the position of the circular cutter 43. When the third electric cylinder 4 extends to drive the square mounting plate 41, the cutting motor 42 and the circular cutter 42 to move upward, the circular cutter 43 passes upward through the cutting reserved opening 12 to cut the hollow plate on the surface of the cutting operating table 1.

[0031] Working method: Place the hollow plate on the cutting operation table 1, extend the first electric cylinder 2 to drive the side clamping plate 21 to move inward along the surface of the cutting operation table 1, use the rubber limiting belt 24 to abut the two sides of the hollow plate, and then extend the second electric cylinder 3 to drive the U-shaped lower pressing block 31 to move downward, and abut the surface of the hollow plate at the upper end of the cutting reserved opening 12 through the lower pressing roller 32, and abut the surface of the hollow plate downward to prevent bulging at the center cutting position to affect the cutting effect;

[0032] Because the side abutment rollers 23 are rotatably mounted on the inner side of the mounting groove 22 and can rotate along the mounting groove 22, when the hollow plate is pushed to move along the surface of the cutting table 1, the rubber limiting belt 24 will drive the side abutment rollers 23 to rotate along the mounting groove 22 and the lower pressure roller 32 is rotatably connected to the inner side of the U-shaped lower pressure block 31 and can rotate along the U-shaped lower pressure block 31. When the hollow plate is pushed, the lower pressure roller 32 rolls on the surface of the hollow plate, thereby reducing the friction between the side clamping plate 21 and the hollow plate and the U-shaped lower pressure block 31 and the hollow plate, making it convenient to smoothly push the hollow plate to move along the surface of the cutting table 1 for cutting.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
