Description

Technical Field

[0001] This application relates to the field of metal sandwich panel technology, and in particular to a metal plate trimming device. Background Technology

[0002] Metal-faced sandwich panels are structural panels consisting of two layers of thin metal sheets and a core of rigid insulation material such as rock wool or rigid foam plastic, assembled on a dedicated automated production line. Due to their rich colors, aesthetically pleasing structure, ease of high-capacity prefabrication in factories, and advantages such as fire resistance and high strength, metal-faced sandwich panels are widely used in various building and cold storage construction projects.

[0003] When metal sandwich panels are used in different applications, the materials and dimensions of the upper and lower metal panels are often different. For example, when used as building roofs or walls, the widths of the inner and outer metal panels vary greatly in order to meet requirements for aesthetics and structural strength, and the widths are rarely integers.

[0004] Due to the continuous nature of metal sheet production, metal sheet manufacturers typically supply sheets of fixed integer widths. Furthermore, each batch of a particular specification requires large-volume production.

[0005] Furthermore, while existing cutting methods can produce metal sheets of the corresponding specifications, they require processing the entire roll of metal separately, resulting in poor flexibility. Additionally, the cut strips need to be collected manually, taking up a lot of space, consuming a lot of labor, and sometimes posing safety concerns.

[0006] In view of this, it is necessary to improve the existing metal sheet trimming device to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a metal sheet trimming device to solve the problem that existing cutting methods require manual collection of the trimmed strips, resulting in significant manpower and space consumption. Crucially, it can be used in conjunction with automated production lines without incurring any additional processing time.

[0008] To achieve the above objectives, the present invention provides a metal plate trimming device for trimming metal plates. The metal plate trimming device includes a roller shear for trimming the metal plate, a slicing cover for receiving the trimmed edge material, a pressure roller disposed within the slicing cover for clamping and conveying the edge material, a shearing component disposed within the slicing cover for cutting the edge material into small pieces, and a driving assembly. The driving assembly includes a driving component and a pulley assembly connected to the driving component and connecting the roller shear and the pressure roller. The driving component and the shearing component are connected.

[0009] As a further improvement of the present invention, the shearing member includes a shearing bracket and a first cutter disposed at both ends of the shearing bracket. The shearing bracket is connected to the driving member to drive the first cutter to rotate. The first cutter is used to cut off the edge material.

[0010] As a further improvement of the present invention, the metal plate trimming device further includes a second cutter disposed inside the slicing cover, the second cutter being located below the edge material, and the first cutter and the second cutter pressing the edge material to cut it off.

[0011] As a further improvement of the present invention, the pressure roller includes a first pressure roller connected to and driven to rotate by the driving member, a second pressure roller disposed below the first pressure roller, and an elastic member for supporting the second pressure roller to adjust the distance between the second pressure roller and the first pressure roller, wherein the edge material is located between the first pressure roller and the second pressure roller.

[0012] As a further improvement of the present invention, the slicing cover is provided with a flared opening on the side facing the roller shear for allowing edge material to enter.

[0013] As a further improvement of the present invention, the height of the roller shear is higher than the height of the pressure roller in the vertical direction.

[0014] As a further improvement of the present invention, the roller shear includes a rotating shaft connected to the pulley assembly to drive the pulley assembly to work, and two metal rubber roller shear wheels connected to one end of the rotating shaft. The metal rubber roller shear wheels are used to push and cut the metal plate.

[0015] As a further improvement of the present invention, the roller shear also includes a gearbox connected to the rotating shaft, the driving component includes a drive motor and a reducer, the drive motor is connected to the gearbox to drive the rotating shaft to rotate, and the reducer is used in conjunction with the pulley assembly.

[0016] As a further improvement of the present invention, the metal plate trimming device further includes a first mounting base for mounting the roller shear, the slicing cover, the pressure roller, the shearing component, and the drive assembly.

[0017] As a further improvement of the present invention, the number of the roller shear, the slicing cover, the pressure roller, the shearing component, the driving assembly, and the first mounting base are all two, and the two first mounting bases are arranged on both sides of the metal plate to cut both sides of the metal plate simultaneously.

[0018] As a further improvement of the present invention, the metal plate trimming device further includes a second mounting base, a guide rail disposed on the upper surface of the second mounting base, a hand crank screw disposed on the upper surface of the second mounting base, and a handwheel for driving the hand crank screw. The first mounting base is mounted on the guide rail and the hand crank screw, and the handwheel is used to drive the first mounting base to move along the hand crank screw and move along the guide rail.

[0019] The beneficial effects of this invention are as follows: The metal sheet trimming device of this invention can continuously and quickly cut metal sheets to the target width without generating additional production or waiting time. It can be stopped at any time according to use. It can cut edge material into small sheet-like metal rolls, significantly reducing the volume of trimming waste during storage, making it convenient for collection and recycling, and avoiding the safety risks to operators from the sharp edges of strip metal. It avoids the problems of large volume and difficulty in storing tangled strip metal, as well as potential safety hazards. Attached Figure Description

[0030] like Figures 1 to 6 As shown, the metal plate trimming device 100 of the present invention is used to trim a metal plate 200. The metal plate trimming device 100 includes a roller shear 1 for trimming the metal plate 200, a slicing cover 2 for receiving the trimmed edge material 201, a pressure roller 3 disposed in the slicing cover 2 for clamping and conveying the edge material 201, a shearing component 4 disposed in the slicing cover 2 for cutting the edge material 201 into small pieces, a second cutter 5 disposed in the slicing cover 2, a drive assembly 6, a first mounting base 7, a second mounting base 8, a guide rail 9 disposed on the upper surface of the second mounting base 8, a hand crank screw 10 disposed on the upper surface of the second mounting base 8, and a handwheel 101 for driving the hand crank screw 10.

[0031] The driving assembly 6 includes a driving component 61 and a pulley assembly 62 connected to the driving component 61 and connecting the roller shear 1 and the pressure roller 3. The driving component 61 is connected to the shearing component 4. In this embodiment, only one set of driving component 61 and pulley assembly 62 is needed to drive the roller shear 1, the pressure roller 3 and the shearing component 4 to work.

[0032] The driving component 61 includes a drive motor 611 and a reducer 612.

[0033] The roller shear 1 includes a rotating shaft 11 connected to the pulley assembly 62 to drive the pulley assembly 62, two metal-rubber roller shear wheels 12 connected to one end of the rotating shaft 11, and a gearbox 13 connected to the rotating shaft 11. A drive motor 611 is connected to the gearbox 13, driving the rotating shaft 11 to rotate, which in turn drives the metal-rubber roller shear wheels 12 to rotate. The metal-rubber roller shear wheels 12 are used to push and cut the metal plate 200. When the metal-rubber roller shear wheels 12 rotate, they can both cut and trim the edges of the metal plate 200 and move the metal plate 200 forward in a horizontal direction.

[0034] The reducer 612 works in conjunction with the pulley assembly 62 to control the operation of the pressure roller 3 in order to cooperate with the operation of the roller shear 1.

[0035] The pressure roller 3 includes a first pressure roller 31 connected to and driven to rotate by the driving member 61, a second pressure roller 32 disposed below the first pressure roller 31, and an elastic member 33 for supporting the second pressure roller 32 to adjust the distance between the second pressure roller 32 and the first pressure roller 31. The edge material 201 is located between the first pressure roller 31 and the second pressure roller 32. The first pressure roller 31 is connected to the pulley assembly 62 so as to be driven to rotate by the pulley assembly 62.

[0036] The rotation of the first pressure roller 31 drives the movement of the edge material 201 between the first pressure roller 31 and the second pressure roller 32, and also drives the second pressure roller 32 to rotate. The elastic element 33 allows edge materials 201 of different thicknesses to enter between the first pressure roller 31 and the second pressure roller 32, and allows the second pressure roller 32 to cooperate with the first pressure roller 31 to press the edge material 201. That is, the greater the thickness of the edge material 201, the more the elastic element 33 is compressed, and the greater the distance between the first pressure roller 31 and the second pressure roller 32. The pressure between the first pressure roller 31 and the second pressure roller 32 is set to 30N-70N. In this embodiment, the linear speed of rotation of the first pressure roller 31 is the same as the linear speed of the metal-rubber roller shear wheel 12, so that the edge material 201 and the metal plate 200 move at the same speed.

[0037] In the vertical direction, the height of the roller shear 1 is higher than the height of the pressure roller 3, so that when the edge material 201 sinks naturally under the action of gravity, it can enter between the first pressure roller 31 and the second pressure roller 32.

[0038] The slicing cover 2 is provided with a flared opening 21 on the side facing the roller shear 1 for the edge material 201 to enter. The flared opening 21 opens at an angle of 3-10 degrees, which facilitates the entry of the edge material 201.

[0039] The shearing component 4 includes a shearing bracket 41 and a first cutter 42 disposed at both ends of the shearing bracket 41. The shearing bracket 41 is connected to the driving component 61 to drive the first cutter 42 to rotate. The first cutter 42 is used to cut off the edge material 201.

[0040] The second cutter 5 is located below the edge material 201, and the first cutter 42 and the second cutter 5 press the edge material 201 to cut it off.

[0041] This embodiment employs a double-blade fixing method. The second blade 5 is fixed, while the first blade 42 rotates. The edge material 201 is conveyed forward, moving to a position beyond the edge of the second blade 5 and gradually extending outward. The shearing bracket 41 is connected to the reducer and pulley assembly 62, rotating at a set speed. This rotation brings the blade of the first blade 42 into position, where it engages with the second blade 5 to perform a shearing action, thereby cutting off the edge material 201. The cut edge material 201 falls naturally under gravity, facilitating recycling.

[0042] The number of the roller shear 1, the slicing cover 2, the pressure roller 3, the shearing component 4, the driving assembly 6, and the first mounting base 7 are all two. The two first mounting bases 7 are disposed on both sides of the metal plate 200 to simultaneously cut both sides of the metal plate 200. In other embodiments, only one set of first mounting bases 7 may be provided on one side to cut only one side of the metal plate 200.

[0043] The first mounting base 7 is used to mount the roller shear 1, the slicing cover 2, the pressure roller 3, the shearing component 4, and the drive assembly 6. The first mounting base 7 is mounted on the guide rail 9 and the hand crank screw 10. The handwheel 101 is used to drive the first mounting base 7 to move along the hand crank screw 10 and then along the guide rail 9. The guide rail 9 is perpendicular to the width direction of the metal plate 200. Thus, by moving the first mounting base 7, the position of the roller shear 1 and the pressure roller 3 relative to the metal plate 200 can be moved, thereby controlling the cutting width of the metal plate 200.

[0044] The metal plate trimming device 100 of the present invention is used as follows:

[0045] According to the required width of the metal plate 200, rotate one or both hand crank screws 10 to drive the first mounting base 7 to move relative to the second mounting base 8 to the corresponding position; start the drive motor 611 to drive the roller shear 1 to work, so as to cut the metal plate 200 to the specified width and drive the metal plate 200 to move towards the pressure roller 3; the edge material 201 cut off from both sides moves downward under the action of gravity until it enters the slicing cover 2 and enters between the first pressure roller 31 and the second pressure roller 32. The first pressure roller 31, driven by the pulley assembly 62, drives the edge material 201 forward at the same speed as the rollers. The shearing bracket 41 rotates, driving the first cutter 42 to rotate, and cuts the edge material 201 at the position close to the second cutter 5. The cut edge material 201 falls naturally under the action of gravity, and a recycling box for collecting the cut edge material 201 can be set below.

[0046] The metal sheet trimming device 100 of this invention is directly installed between the uncoiling and forming processes of a sandwich panel production line. It processes continuously during sandwich panel production without incurring any additional production time. It can continuously and quickly cut the metal sheet 200 to the target width without generating extra production or waiting time, and can be stopped at any time as needed. It can cut the edge material 201 into small pieces of metal coil trimming waste, significantly reducing its volume during storage, facilitating collection and recycling, and avoiding the safety risks to operators from sharp metal strips. It avoids the problems of large volume and difficulty in storing tangled metal strips, as well as potential safety hazards.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
