Description

Technical Field

[0001] The utility model relates to the technical field of sheet cutting, in particular to an automatic fixed-length cutting sawing machine. Background Art

[0002] In the production process of laminates or molded boards, large-sized laminates or molded boards need to be cut into small-sized boards according to customer requirements, so as to put the laminates or molded boards into specific working environments for use.

[0003] As described above, in order to efficiently complete the cutting work of the boards, mechanical equipment is generally used to cut the boards. When using the mechanical equipment as shown in the appendix Figure 8 to cut the board, the operator needs to place the whole board on the mechanical equipment, and then operate the mechanical equipment to complete the cutting process of the board according to the preset parameters. Or use a composite material board cutting machine disclosed in a Chinese patent with the patent publication number CN101758513B to complete the cutting process of the board. The board cutting machine includes a digital display, a pneumatic control unit, a workbench, a vacuum cleaner, a scale, a moving carriage, a cutting saw and a pneumatic motor. The cross beam is fixed on one side of the workbench; the linear guide rail is located on the surface of the cross beam connecting plate. The moving carriage is fixed on the slider; the pneumatic motor and the cutting saw are installed on the moving carriage. The digital ruler is fixed on the cross beam connecting plate; the scale is located at one end of the workbench. The digital display and the pneumatic control unit are located above the cross beam column at one end of the workbench. The present invention obtains a high-straightness board edge through a high-precision guide rail, and the digital ruler and the digital display adopted make the equipment operation simple, realizing the mechanical cutting of composite material boards, and having the characteristics of simple structure, convenient use, low cost and high cutting efficiency.

[0004] Whether using the mechanical equipment shown in the appendix Figure 8 or the mechanical equipment provided by the above patent, the whole board needs to be placed on the mechanical equipment, and the whole board is cut into multiple separated small-sized boards by the mechanical equipment. In this way, although the cutting process of the board can be realized, in order to ensure the safety of the operator, it is generally required that during the operation of the mechanical equipment, the board located on the mechanical equipment should not be transferred, that is, only after the whole board is cut can the board located on the mechanical equipment be cleaned to facilitate the placement of the next whole board. Therefore, relatively speaking, the efficiency of cutting a batch of boards by this mechanical equipment is low. In addition, the sizes of the appendix Figure 8 and the device provided by the above patent are relatively large, that is, the area of the whole platform for placing the board is large. Even during the operation of the mechanical equipment, when the operator transfers the small-sized boards that have been cut, he needs to move around the mechanical equipment because the length and width of the mechanical equipment are relatively large, which is not conducive to the operator completing the transfer of multiple boards at one edge of the mechanical equipment, and invisibly increases the complexity of the operator's work.

DETAILED DESCRIPTION

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0026] As described in the background art, Figure 8 When the mechanical equipment shown cuts the plates, in order to ensure safety, the staff is generally not allowed to clean the cut plates before the entire plate is placed on the mechanical equipment and stops working. They can only be cleaned uniformly after the cutting is completed. This method reduces the efficiency of plate cutting. Therefore, in actual production, the staff will clean the cut plates one by one while the mechanical equipment is cutting the plates. This method is very dangerous. In addition, because the length and width of the mechanical equipment are large, when the staff cleans the cut plates, they need to move around the mechanical equipment according to the distribution of the plates to achieve the cleaning of the plates, that is, the staff cannot complete the cleaning of the plates at the same edge of the mechanical equipment. This method is more cumbersome.

[0027] like Figure 1 , Figure 5 , Figure 6As shown in the figure, in order to reduce the risk coefficient of the staff during the sheet cutting process and facilitate the cleaning of the sheet, this embodiment provides a device for sheet cutting. Specifically, it includes a bracket 1 and a cutting component 4. A workbench 12 is provided at the top of the bracket 1, and a notch 13 is provided on the workbench 12, and the notch 13 faces the middle of the bracket 1. The cutting component 3 includes a saw blade 31, a sleeve 33, a guide rail 34, and a threaded rod 36. The central axis of the saw blade 31 is connected to the output shaft of the motor. The top of the saw blade 31 can penetrate through the notch 13. The sleeve 33 is sleeved on the central axis of the saw blade 31, and a sliding column 331 can be fixedly provided below the sleeve 33. A support frame 332 is fixedly provided on the side of the sliding column 331. A guide groove 341 is provided on the guide rail 34, and a driving screw 47 is provided in the guide groove 341. The end of the driving screw 47 is connected to the motor. The sliding column 331 is arranged in the guide groove 341, and the driving screw 47 threadedly penetrates through the sliding column 331. The support frame 332 is attached to the guide rail 34, and the motor connected to the saw blade 31 is connected to the support frame 332. Under the operation of the motor, the saw blade 31 can rotate at a high speed. While the saw blade 31 rotates at a high speed, the motor can control the driving screw 47 to rotate. Since the driving screw 47 threadedly penetrates through the sliding column 331, the high-speed rotating saw blade 31 can be controlled to move along the length direction of the notch 13, thereby realizing the cutting process of the sheet.

[0028] As Figure 2 , Figure 5 shown, in order to be able to adapt to sheets of different thicknesses, end plates 32 are connected to both ends of the guide rail 34 by bolts. A buckle column 35 is provided at the end of the end plate 32, and a threaded rod 36 is threadedly penetrated. The end of the threaded rod 36 is connected to the motor. At the same time, a buckle groove 11 is provided on the side wall of the bracket 1. The central angle of the buckle groove 11 is greater than 180°, and an enlarged groove (i.e., the size at this place is larger than the size of the rest of the buckle groove 11) is provided at the lower end. The buckle column 35 can pass through the enlarged groove and enter the buckle groove 11. With the cooperation of the buckle groove 11 and the buckle column 35, the end plate 32 is stably and movably arranged on the bracket 1, providing support for the threaded rod 36 to rotate and adjust the position of the end plate 32, thereby adjusting the height of the saw blade 31 protruding from the workbench 12 to adapt to sheets of different thicknesses.

[0029] As Figure 2 , Figure 3 , Figure 4As shown in the figure, in order to control the movement of the sheet material located above the workbench 1, mounting grooves 14 are provided at both ends of the workbench 12. The mounting grooves 14 are arranged along the length direction of the workbench 12 and are distributed on both sides of the notch 13 of the workbench 12. A stepped groove 15 is provided on the side wall of the mounting groove 13, and a limiting plate 16 is connected by bolts at the stepped groove 15. Conveying devices 5 are provided at the mounting grooves 14. The conveying devices 5 include an endless belt 51, supporting rollers 52 and a driving shaft 53. Multiple supporting rollers 52 are evenly distributed and penetrate through the annular plate 51. The driving shaft 53 penetrates through the supporting rollers 52 and is connected to a motor. The end shafts of the supporting rollers 52 extend into the space formed by the stepped groove 15 and the limiting plate 16. At the same time, the upper side of the endless belt 51 is higher than the upper side of the workbench 1. When the motor controls the driving shaft 53 to rotate, the endless belt 51 can be controlled to rotate, thereby supporting the movement of the sheet material located above the endless belt 51, that is, cutting a small-sized sheet material, and then the movement of the small-sized sheet material can be controlled to separate from the workbench 12. The end shafts of the supporting rollers 52 extend into the space between the limiting plate 16 and the stepped groove 15, and the limiting plate 16 can be quickly disassembled and assembled, which provides convenience for repairing or replacing the conveying device 5 according to requirements.

[0030] As Figure 1 , Figure 7 shown, a detection assembly 4 can also be provided at the end of the workbench 12 to measure the size of the sheet material through the detection assembly 4. Specifically, the detection assembly 4 includes a vertical frame 41, a horizontal plate 42 and two baffle plates 44. The two baffle plates 44 are respectively sleeved at both ends of the horizontal plate 42 and are both threadedly sleeved at both ends of the same bidirectional screw 45. An infrared rangefinder 43 is provided on one baffle plate 44. A rotating motor 46 is provided above the horizontal plate 42. The top of the rotating motor 46 is sleeved on the vertical frame 41 and is threadedly penetrated with a driving screw 47. The driving screw 47 is arranged above the vertical frame 41. The bidirectional screw 45 and the driving screw 47 are respectively connected to a motor. After the cut sheet material moves to directly below the detection assembly 4, the conveying device 5 used to support the movement of the cut sheet material stops working, and the motor is used to control the driving screw 47 and the bidirectional screw 46 to rotate, adjusting the positions of the baffle plates 44 so that the two baffle plates 44 are distributed on both sides of the sheet material and are in contact with the sheet material, and the width or length of the sheet material is measured through the operation of the infrared rangefinder 43. After measuring the width or length, under the operation of the rotating motor 46, the horizontal plate 42 is controlled to rotate, changing the positions of the baffle plates 44, which provides convenience for measuring another data. In actual production, an industrial camera can also be installed on the side of the rotating motor 46 according to actual needs to capture the position of the sheet material through the industrial camera. If the measured data of the sheet material does not meet the standard, an alarm is issued to remind the staff to remove the sheet material.

[0031] As Figure 1As shown, in order to stably place the plate to be slit relative to the workbench 12, a limiting roller 2 can be provided at one end of the workbench 12 away from the detection component 4. The limiting roller 2 contacts the upper side of the plate, and a wheel body is provided on the limiting roller 2, and the wheel body is located at the edge of the plate.

[0032] The above-mentioned motor, infrared rangefinder 43, etc. are all electrically connected to the control box 17, and a display screen and an alarm can also be provided on the control box 17 for the staff to operate by touching the screen.

[0033] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
