Description

Technical Field

[0001] This utility model relates to the field of foam insulation board cutting devices, and in particular to a foam insulation board transport device and bottom cutting component. Background Technology

[0002] Polystyrene foam insulation board is a building insulation material made of polystyrene resin, mainly used for building wall and roof insulation. Foam insulation boards are made by foaming raw materials in a mold. After foaming in the mold, the bottom surface may be slightly uneven, and some foam particles may be suspended, which is not conducive to subsequent cutting of insulation boards of the same size. This also affects the practicality and aesthetics of the insulation board. In existing technology, when transporting the foamed insulation board, a saw blade is usually placed at the bottom to cut it flat. However, because the part to be cut is relatively thin, and the foamed insulation board has a certain weight, the saw blade cuts horizontally, requiring a single, complete cut. This results in high cutting resistance, difficulty in cutting, and an inability to guarantee the flatness of the cut. Utility Model Content

[0003] To overcome the problem in the background art that saw blades are not easy to cut the bottom surface of foam insulation boards flat, this utility model provides a foam insulation board transport device and a bottom cutting component. By setting a rotatable roller cutter, and the rotation direction of the roller cutter and the cutting edge of the side blade are both facing the movement direction of the foam insulation board, the side blade can rotate downward to cut the bottom surface of the foam insulation board, and the overall cut is distributed into multiple cutting points, which can greatly reduce the resistance of each cut, greatly reduce the cutting resistance, make cutting easier, and maintain a high degree of flatness after cutting.

[0004] The technical solution of this utility model is as follows: A foam insulation board transport device and a bottom cutting assembly are disclosed. The device includes a transport device installed in a frame to transport foam insulation boards and a cutting assembly for cutting the bottom of the foam insulation boards. The cutting assembly includes a rotatable roller cutter with several rows of side blades on its circumference. The rotation direction of the roller cutter and the orientation of the cutting edges of the side blades are both opposite to the movement direction of the foam insulation board.

[0005] Compared with existing technologies, the beneficial effects of this technical solution are as follows: When the roller cutter rotates, its side blades rotate downwards to cut the bottom surface of the foam insulation board. Compared with the horizontal cutting in the prior art, this cutting angle can significantly reduce cutting resistance and make cutting easier. By setting multiple rows of side blades, the overall cutting can be distributed into multiple cutting points, which can significantly reduce the resistance of each cut and improve the flatness of the cut. The bottom surface of the foam insulation board can be flatter after cutting.

[0006] Preferably, the side cutting edges of each row are arranged spirally along the circumference of the hob, and the side cutting edges of adjacent rows are arranged alternately.

[0007] Its beneficial effects are as follows: by setting the side blades arranged in an alternating spiral trajectory, the cutting points can work continuously and alternately when the roller cutter rotates, which improves the cutting efficiency. Moreover, the alternating arrangement can cut every part of the bottom surface of the foam insulation board in place, ensuring the overall flatness.

[0008] More preferably, the roller cutter is a cylindrical structure, arranged horizontally and perpendicular to the direction of movement of the foam insulation board, with one end fixedly connected to the output shaft of the motor and the other end fixed in the bearing in the mounting base.

[0009] Its beneficial effects are as follows: the cylindrical structure and arrangement direction are more conducive to the smooth cutting of the bottom surface of the foam insulation board by the roller cutter; the motor provides power for the rotation of the roller cutter, and the roller cutter can rotate freely under the constraint of the bearing.

[0010] More preferably, the side blade is mounted on a helical protrusion on the circumferential surface of the hob and is evenly arranged along the length of the helical protrusion.

[0011] Its beneficial effect is that the side blades are arranged on the spiral protrusions, making it easier to cut the bottom surface of the foam insulation board.

[0012] More preferably, the side blade is a rectangular blade, which is fixed to the surface of the spiral protrusion by fasteners, and its cutting edge extends beyond the side of the spiral protrusion.

[0013] Its advantages are: by using fasteners for fixing, it is easier to replace the side blade; the cutting edge of the side blade extends beyond the side of the spiral protrusion, allowing the side blade to cut smoothly on the bottom surface of the foam insulation board.

[0014] Preferably, the transport device includes several rollers installed in the frame, the rollers are arranged horizontally and evenly distributed along the transport direction, and rotate by chain drive; the foam insulation board is placed on the surface of the rollers, and the rotation of the rollers drives the foam insulation board to move.

[0015] Its beneficial effects are: the rollers are used to support and transport the foam insulation boards, and this transportation method can greatly reduce transportation resistance.

[0016] More preferably, the roller is parallel to the cutter and lower than the cutter, with a height difference of 6-10 mm between them.

[0017] Its beneficial effect is that this height difference range can keep the bottom surface of the foam insulation board flat and avoid the problem of excessive cutting.

[0018] Preferably, it also includes guide devices arranged on both sides of the foam insulation board. Each guide device includes several vertically arranged guide wheels, which are evenly distributed along the transport direction and are connected to the side of the foam insulation board.

[0019] Its beneficial effects are as follows: the guide wheel is used to guide the movement of the foam insulation board and prevent the foam insulation board from deviating from the normal transportation track. When the foam insulation board moves, it can drive the guide wheel to rotate. This guiding method reduces the frictional resistance between the foam insulation board and the guide wheel, and further reduces the transportation resistance.

[0020] More preferably, the conveyor belt is driven by a vertically arranged drive roller; the conveyor belt is arranged inside the cover, and the upper and lower ends of the guide roller shaft are fixedly connected to the cover.

[0021] Its beneficial effects are: the cover is used to install and fix the guide wheels, and also provides a certain degree of protection.

[0022] More preferably, the side of the cover closest to the foam insulation board has an open structure, and the cover is fixedly connected to the frame by fasteners.

[0023] Its beneficial effects are: it facilitates the guide wheel 21 to contact the side of the foam insulation board through the opening, and the fasteners are used to fix the cover to the frame.

Detailed Implementation To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example 1: As Figs. 1-2The illustration shows a foam insulation board transport device and a bottom cutting assembly. The device includes a transport unit installed within a frame 1 for conveying foam insulation boards 5, and a cutting assembly for cutting the bottom of the foam insulation boards 5. The transport unit is located between two frames 1 on either side. The frames 1 are fixed to the ground by lower columns 11 and extend from the transport starting point to the transport endpoint. The transport unit transports the foam insulation boards 5 from the transport starting point to the transport endpoint. The foam insulation board 5 is a polystyrene foam insulation board.

[0026] The cutting assembly includes a rotatable roller cutter 3. The circumference of the roller cutter 3 is provided with several rows of side blades 31, with a certain gap between each row of side blades 31. The rotation direction of the roller cutter 3 and the orientation of the cutting edge 32 of the side blades 31 are opposite to the moving direction of the foam insulation board 5. That is, the rotation direction of the roller cutter 3 and the orientation of the cutting edge 32 of the side blades 31 are both towards the moving direction of the foam insulation board 5. When the roller cutter 3 rotates, its side blades 31 rotate downward to cut the bottom surface of the foam insulation board 5. Compared with the horizontal cutting in the prior art, this cutting angle can significantly reduce cutting resistance and make cutting easier. By setting multiple rows of side blades 31, the overall cutting can be distributed into multiple cutting points, which can significantly reduce the resistance of each cut and improve the cutting flatness. The bottom surface of the foam insulation board 5 can be flatter after cutting.

[0027] Example 2: Based on Example 1, the side blades 31 are optimized. Each row of side blades 31 is spirally arranged around the circumference of the roller cutter 3, and adjacent rows of side blades 31 are staggered, meaning that the interval between adjacent side blades 31 is the same and they partially overlap in the rotation direction of the roller cutter 3. By setting the side blades 31 to be staggered according to the spiral trajectory, the cutting points can work continuously and alternately when the roller cutter 3 rotates, improving cutting efficiency. Furthermore, the staggered arrangement can cut every part of the bottom surface of the foam insulation board 5 to the required depth, ensuring overall flatness.

[0028] Preferably, the roller cutter 3 is a horizontally arranged cylindrical structure, with its arrangement direction perpendicular to the moving direction of the foam insulation board 5. This structure and arrangement direction are more conducive to the roller cutter 3 making a smooth cut on the bottom surface of the foam insulation board 5. One end of the roller cutter 3 is connected to the output shaft of the motor 34 via a key connection, and the other end is fixed in a bearing in the mounting base 36. The motor 34 provides power for the rotation of the roller cutter 3. By controlling the speed of the motor 34 to 1435 rpm, the roller cutter 3 can make better cuts at a suitable speed. The motor 34 is fixed on the support frame 35. The support frame 35 and the mounting base 36 can be directly fixed to the ground or mounted on the two side frames 1.

[0029] Preferably, the side blade 31 is mounted on the spiral protrusion 33 on the circumferential surface of the roller cutter 3 and is evenly distributed along the length of the spiral protrusion 33. The spiral protrusion 33 is spirally arranged on the circumferential surface of the roller cutter 3, that is, it extends along a spiral trajectory and extends upward beyond the circumferential surface of the roller cutter 3. The side blade 31 is arranged on the spiral protrusion 33, which makes it easier to cut the bottom surface of the foam insulation board 5. In addition, the side blade 31 is a rectangular blade and is fixed to the surface of the spiral protrusion 33 by fasteners. The fasteners can be screws. This detachable fixed connection method is more conducive to the replacement of the side blade 31. The cutting edge 32 of the side blade 31 extends beyond the side of the spiral protrusion 33. This side is opposite to the moving direction of the foam insulation board 5. This arrangement allows the side blade 31 to cut the bottom surface of the foam insulation board 5 smoothly. Example 3: Based on Example 1, a preferred design is made. The transport device includes several rollers 4 installed in the frame. The rollers 4 are arranged horizontally and evenly along the transport direction. The two ends of their roller shafts 41 pass through side plates 12 fixed to the inner side of the frame 1. The rollers 4 rotate via chain drive. That is, two sets of sprockets 42 are fixed to one end of the roller shaft 41. The sprockets 42 of two adjacent rollers 4 are connected one-to-one by chains 43. Power is input from the drive sprocket connected to the drive motor, and then transmitted to the sprockets 42 through the chains 43. The rotation of the sprockets 42 drives the rollers 4 to rotate. The rotation of the rollers 4 then drives the subsequent rollers 4 to rotate in sequence through the sprockets 42 and chains 43. The foam insulation board 5 is placed on the surface of the rollers. When the rollers 4 rotate, they drive the foam insulation board 5 to move.

[0030] Furthermore, the roller cutter 3 can be arranged between any adjacent rollers 4, parallel to the rollers 4, and the spacing between the roller cutter 3 and the two side rollers 4 is the same as the spacing between adjacent rollers 4. The foam insulation board 5 passes through the rollers 4 and the roller cutter 3. The rollers 4 drive the foam insulation board 5 to move. When the foam insulation board 5 passes through the roller cutter 3, its bottom surface is cut flat, and then it continues to be transported forward through the rollers 4. The rollers 4 are used to support and transport the foam insulation board 5. This transportation method can greatly reduce transportation resistance.

[0031] In this embodiment, the roller 4 is parallel to and lower than the cutter 3, with a height difference of 6-10mm. The height difference between the roller 4 and the cutter 3 is the cutting thickness of the cutter 3 on the bottom surface of the foam insulation board 5. The specific cutting thickness can be set according to the specific situation of the foam insulation board 5 after foaming and molding. After cutting with the set cutting thickness, the bottom surface of the foam insulation board 5 remains flat, and there will be no situation of incomplete cutting or over-cutting. In this embodiment, the height difference between the roller 4 and the cutter 3 is 8mm, which can keep the surface of the foam insulation board 5 flat and prevent over-cutting.

[0032] Example 4: Based on Example 1, the transportation device is optimized and further includes guide devices arranged on both sides of the foam insulation board 5. Each guide device includes several guide wheels 21, which are vertically arranged on both sides of the foam insulation board 5 and evenly arranged along the moving direction of the foam insulation board 5. The guide wheels 21 are in contact with the side of the foam insulation board and are used to guide the movement of the foam insulation board 5 to prevent the foam insulation board 5 from deviating from the normal transportation trajectory. When the foam insulation board 5 moves, it can drive the guide wheels 21 to rotate. This guiding method reduces the frictional resistance between the foam insulation board 5 and the guide wheels 21, and further reduces the transportation resistance.

[0033] Preferably, the guide wheel 21 is arranged inside the cover 23, and the upper and lower ends of the axle 22 of the guide wheel 21 are fixedly connected to the cover 23. The cover 23 has an open structure in the shape of "]" for installing and fixing the guide wheel 21 and providing a certain degree of protection. The side of the cover 23 closest to the foam insulation board 5 is open, which facilitates the guide wheel 21 to contact the side of the foam insulation board 5 through the opening. The cover 23 is fixed to the upright plate 13 on the outer surface of the frame 1 by fasteners, which can be long bolts.

[0034] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
