Description

Technical Field

[0001] The invention relates to the field of cutting technology, in particular to cutting equipment for building panels, and specifically refers to an online synchronous cutting machine. Background Art

[0002] In the production process of building components, for board-type components such as cement boards, they are usually first made into long strips and then cut into the required length as needed.

[0003] When cutting plates to length, the plate production line of the prior art is stationary. After the cutting is completed, the plate can continue to move to cut the next plate, which is very inefficient. In addition, most of the existing online cutting machines use the bevel cutting method, but this kind of cutting machine cannot solve the problem of too wide chip removal gap of the cutting pad, resulting in poor cutting quality and unsightly cutting seams. In addition, when cutting long plates with poor strength, the plate is very easy to break due to the lack of a transition support structure. Summary of the invention

[0004] In view of the shortcomings of the cutting machines in the prior art, the present invention provides an online synchronous cutting machine, which can complete the fixed-length cutting of the plates moving online while avoiding affecting the normal operation of the plates on the production line.

[0005] The present invention is achieved through the following technical scheme, providing an online synchronous cutting machine, including a traveling frame moving along the plate conveying direction, a plate supporting device relatively stationary with the traveling frame, and a cutting device installed on the traveling frame and moving along the cutting direction.

[0006] When the present solution is in use, the plate to be cut is placed on the plate supporting device, so that the traveling frame, the plate and the cutting device move synchronously along the plate conveying direction, thereby ensuring that the cutting device and the plate are relatively stationary in the plate conveying direction, and realizing the synchronous movement of the cutting device and the plate in the plate conveying direction. Through the movement of the cutting device along the cutting direction, online synchronous cutting of the plate is realized, and the cutting direction is the width direction of the plate, which is perpendicular to the plate conveying direction.

[0007] As an optimization, the plate support device is provided with a plate clamping and fixing device. This optimization solution fixes the plate by providing the plate clamping and fixing device, thereby preventing the plate from shifting during the cutting process and improving the cutting quality.

[0008] As an optimization, the plate clamping and fixing device includes clamping cylinders located on both sides of the plate, the cylinder body of the clamping cylinder is fixedly connected to the side frame, and a clamping plate is installed on one end of the clamping cylinder piston facing the plate. This optimization solution fixes the plate by the clamping cylinder, and the clamping and loosening actions are rapid, which is conducive to improving production efficiency. By setting the clamping plate, the contact area with the plate is increased to prevent the plate from being clamped.

[0009] As an optimization, the plate support device is further provided with a support plate supported on the bottom surface of the plate, and the support plate is provided with a support plate gap located below the cutting gap of the plate. This solution prevents corner drop and edge collapse at the lower end of the cutting gap during cutting by providing the support plate and the support plate gap.

[0010] As an optimization, it also includes a number of fixed rollers installed on the fixed frame and supporting the plate; the plate support device includes two side frames slidably mounted on the fixed track and respectively located on both sides of the fixed frame, and a number of movable rollers supporting the plate are installed on both side frames. This optimization scheme forms a pull-out roller conveying mechanism through the fixed frame located in the middle and the two side frames located on both sides of the fixed frame. Before cutting, the side frames and the movable rollers move as a whole to convey the plate, and send the front of the plate to the conveying device in front of the cutting machine. After cutting, the plate moves to the next process under the action of the front conveying device, and the side frames and the walking frame move backward to reset. At this time, the subsequent plates are supported by the fixed rollers, which solves the problem of the cutting device supporting the plate when cutting the plate and resetting the cutting machine.

[0011] As an optimization, the side frame is fixedly connected to the traveling frame. This optimization scheme realizes the relative stillness of the side frame and the traveling frame by means of fixed connection, ensures the reliability of synchronous movement of the two, and uses only one set of power device to drive the traveling, thus simplifying the structural setting.

[0012] As an optimization, the cutting device includes a cutting motor with a cutting saw blade installed, an upper slider slidably mounted on a traveling frame, and a transverse driving device driving the upper slider to move in the width direction of the plate, and a vertical driving device driving the cutting motor to move vertically is installed on the upper slider. The setting of this optimization scheme realizes the vertical and transverse movement of the cutting motor and the cutting saw blade. The cutting saw blade first moves down to the cutting height, then moves horizontally for cutting, and rises after the cutting is completed, making the cutting action more stable and avoiding the tilting of the cutting seam, which is conducive to reducing the width of the support plate seam and improving the support and protection of both sides of the lower end of the cutting seam of the plate.

[0013] As an optimization, the vertical drive device is a vertically arranged cutting cylinder, and vertical guide rods fixed to the upper slider are respectively arranged on both sides of the cutting cylinder, and a moving seat for installing the cutting motor is slid upward on the vertical guide rod, and the moving seat is connected to the piston rod of the cutting cylinder. This optimization scheme drives the moving seat to move up and down by the cutting cylinder, thereby driving the cutting motor to move up and down, and the action is fast and reliable. The vertical guide rod is provided to provide a guiding effect, thereby ensuring vertical cutting.

[0014] The beneficial effects of the present invention are as follows: the cutting is achieved during the synchronous movement of the cutting device and the plate, thereby improving the working efficiency; by arranging a support plate and a support plate seam, the cutting seam of the plate is supported, thereby improving the cutting quality and the integrity of the plate after cutting; and by a pull-out roller conveying mechanism, the stability of the cutting and the support of the plate when the cutting machine is reset are guaranteed.

DETAILED DESCRIPTION

[0024] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0025] The cutting machine of this embodiment is located in the cement board production line. In front of the cutting machine is a chain conveying device for conveying the cut boards to the next workstation. Behind the cutting machine is a push plate device for pushing the boards forward, for pushing the boards forward or limiting the backward movement of the boards when the cutting machine is reset. The cutting machine of this embodiment can be used not only for cutting building boards, but also for cutting other non-metallic pipe boards.

[0026] This embodiment provides a structure of an online synchronous cutting machine, such as Figure 1As shown, it includes a traveling frame 1 that moves along the plate conveying direction, a plate supporting device 6 that is relatively stationary with the traveling frame, and a cutting device 3 that is installed on the traveling frame and reciprocates along the cutting direction.

[0027] The walking frame is slidably mounted on the first slide rail on the main frame of the production line, and a walking motor 7 is fixedly mounted on the walking frame, a first gear is mounted on the motor shaft of the walking motor 7, the first gear is meshed with a fixed first rack, the first rack is fixed to the upper end of the L-shaped support frame, and the lower end of the L-shaped support frame is fixedly connected to the main frame, and the first gear is driven by the walking motor to move along the first rack, thereby realizing the movement of the walking frame.

[0028] This embodiment also includes a plurality of fixed rollers 14 installed on the fixing frame 5 and supporting the plate. The fixing frame is fixedly arranged, and the lower end of the legs of the fixing frame is provided with a screw rod for adjusting the height, which is used for leveling the fixing frame as a whole.

[0029] The plate supporting device includes two side frames which are slidably mounted on a fixed rail 16 and are respectively located on both sides of the fixed frame. The side frames are fixedly connected to the walking frame. A plurality of movable rollers 11 for supporting the plate are installed on the two side frames. The movable rollers 11 are parallel to the fixed rollers and are located at the same height to support the plate at the same time.

[0030] A plate clamping and fixing device 13 is provided on the side frame. The plate clamping and fixing device of this embodiment includes clamping cylinders 18 respectively located on both sides of the plate. The clamping cylinders on both sides are arranged opposite to each other, and the cylinder body of the clamping cylinder is fixedly connected to the side frame. A clamping plate 17 is installed at one end of the piston of the clamping cylinder facing the plate 4.

[0031] The plate support device is also provided with a support plate 12 supported on the bottom surface of the plate. The two ends of the support plate are respectively installed on the two side plates. A support plate gap is opened on the support plate and is located directly below the cutting gap of the plate. The support plate gap is opposite to the cutting gap, and the width is adapted to the thickness of the cutting saw blade.

[0032] The cutting device includes a cutting motor 9 equipped with a cutting saw blade 10, an upper slider slidably mounted on a traveling frame crossbeam, and a transverse driving device driving the upper slider to move along the width direction of the plate. The traveling frame is fixed with a transverse rail 19 slidably connected to the upper slider. The transverse driving device includes a transverse motor 2 fixedly connected to the upper slider and a second gear mounted on the motor shaft of the transverse motor. The second gear is meshed with a second rack. The second rack is located below the second gear and is fixedly connected to the traveling frame. In order to improve the synchronization between the plate and the cutting machine, the transverse motor of this embodiment adopts a high-precision servo motor.

[0033] A vertical driving device for driving the cutting motor to move vertically is installed on the upper slider. The vertical driving device is a vertically arranged cutting cylinder 8. Vertical guide rods fixed to the upper slider are respectively provided on both sides of the cutting cylinder. A moving seat 15 for installing the cutting motor is slidably provided on the vertical guide rod, and the moving seat is connected to the piston rod of the cutting cylinder.

[0034] When in use, the plate is clamped by the clamping cylinder so that the plate moves synchronously with the traveling frame, ensuring the synchronization of the cutting machine and the plate along the plate conveying direction when cutting. After the front of the plate is sent to the chain conveyor device, the cutting saw blade moves horizontally to complete the cutting of the plate, and the cutting cylinder drives the cutting saw blade to move upward. The plate moves forward under the action of the chain conveyor device, and the traveling frame drives the side frame to move backward and reset, and the next plate is clamped, conveyed and cut, and the cycle is repeated.

[0035] When cutting a plate, the cutting device moves in both the X direction and the Y direction. The X-direction cutting travel distance D depends on the Y-direction cutting travel speed of the cutting saw blade. If the plate is wide, the Y-direction travel time of the cutting saw blade is long, and the X-direction cutting travel distance D is long. In this case, a roller support device needs to be added to the length of the distance D to prevent the plate from breaking due to vibration during cutting. This embodiment forms a pull-out roller conveying mechanism by setting fixed rollers and movable rollers, which solves the problem of the cutting device supporting the plate when cutting the plate and resetting the cutter.
