Description

Technical Field

[0001] The present application relates to the field of cardboard longitudinal trimming equipment, and in particular to a beam seat mechanism for mounting a board support. Background Art

[0002] Paperboard is also called board paper. It is a thick paper sheet made of various pulps and interwoven fibers.

[0003] After the cardboard is produced, both sides are rough, and both sides need to be trimmed to make the cardboard regular. The production of corrugated cardboard mainly uses computer slitting and trimming machines for cutting, which not only has high production efficiency, but also has high slitting accuracy. The cutting quality of the corrugated cardboard by the computer slitting and trimming machine is mainly determined by the plate support (knife anvil) matched with the cutting wheel. The plate support is composed of a fixed aluminum support and comb teeth. The more fully the plate support supports the corrugated cardboard, the smaller the rough edges of the corrugated cardboard after cutting, and the smaller the trimming width of the corrugated cardboard.

[0004] The utility model patent with patent number CN214265835U discloses a fiberboard support, wherein the cutter is located between the blade combs of the board support when cutting the cardboard. The tetrafluoroethylene board is a support board for supporting the cardboard. When the fiberboard support is used, the cutter is located between the blade combs of the blade comb assembly and is close to the support board without damaging the support board. The position of the cutter and the board support is optimal, and the effect of corrugated cardboard cutting is the best.

[0005] Corrugated cardboard is a multi-layer structure, usually including three-layer, five-layer and seven-layer structures. When cutting cardboard with different layers, the cardboard runs on the frame, and the cutter moves up from the bottom of the cardboard to cut the cardboard. Due to the different thickness of the cardboard, the top surface of the corrugated cardboard keeps in contact with the board support 9, refer to Figure 1 When the setting is just right for cutting five-layer cardboard, the cutter cuts deeper when cutting thin corrugated cardboard (such as three-layer cardboard), and it is easy to cut the support plate of the board support 9, causing damage to the support plate. When cutting thicker corrugated cardboard (such as seven-layer cardboard), the cutter cuts shallower, and the cutter is located farther away from the support plate, which is easy to cause burrs during cutting, affecting the quality of the cardboard. Summary of the invention

[0006] In order to ensure that the cutter always remains in the best position on the board support when cutting cardboards of different thicknesses, the present application provides a beam seat mechanism for mounting the board support on a cardboard cutting device.

[0007] The present application provides a beam seat mechanism for mounting a board support on a cardboard cutting device, which adopts the following technical solution:

[0008] The beam seat mechanism for mounting the board support on the cardboard cutting device comprises a crossbeam and mounting seats symmetrically arranged at both ends of the crossbeam, wherein the mounting seats comprise a fixed seat and a transverse adjustment seat horizontally slidably arranged on the fixed seat; a vertical adjustment seat is vertically slidably connected to the transverse adjustment seat, and the end of the crossbeam is arranged on the vertical adjustment seat;

[0009] A step block is slidably provided on the lateral adjustment seat, and the step block is located below the end of the beam. A plurality of step surfaces are provided on the top surface of the step block, and the horizontal heights of the plurality of step surfaces are different. The step surfaces are used to support the beam, and different step surfaces are replaced after the step block slides to support the beam.

[0010] By adopting the above technical solution, when cutting thin cardboard, the thickness of the thin cardboard is small, the step block slides, so that the lower step surface is located below the cross beam, and after the vertical adjustment seat moves down, the lower step surface supports the cross beam, and the bottom of the board support can just fit the top surface of the thin cardboard. The horizontal adjustment seat slides to adjust the horizontal position of the cross beam, so that when the board support contacts the top surface of the cardboard, the cutter is located close to the support plate when cutting.

[0011] When cutting thin cardboard, the high-stepped surface is located below the crossbeam. After the vertical adjustment seat moves down, the high-stepped surface supports the crossbeam, and the bottom of the board support can just fit the top surface of the thick cardboard. At the same time, the horizontal adjustment seat also slides, so that when the cutter is cutting, the position of the cutter is close to the support plate. The application solution ensures that the position of the cutter is kept close to the support plate when cutting thin or thick cardboard, so that the board support has a good supporting effect on the cardboard, and it is not easy to have burrs when cutting.

[0012] Optionally, a buffer block for abutting the step surface is provided at the bottom of the end of the beam.

[0013] By adopting the above technical solution, the buffer block plays an anti-collision role, reduces damage to components, and reduces noise.

[0014] Optionally, the step surfaces are arranged in a row, the step surfaces are arranged incrementally, and a step cylinder for driving the step block to slide horizontally is arranged on the lateral adjustment seat, and the step cylinder is a multi-position cylinder.

[0015] By adopting the above technical solution, the multi-position cylinder can stop at multiple nodes and have a locking effect, so that the position of the step block is stable, and the step surface is set to be incremental, which is convenient for forming gears. Each sliding displacement of the multi-position cylinder corresponds to a gear, which is convenient for regulation.

[0016] Optionally, an adjusting cylinder is fixed to the side wall of the fixing seat, the piston shaft of the adjusting cylinder is connected to the lateral adjusting seat through a bolt adjusting structure, and the adjusting cylinder drives the lateral adjusting seat to slide laterally;

[0018] By adopting the above-mentioned technical solution, when the plate support is in normal use, the support plate on the plate support will have slight wear, usually 3-5mm. If the plate support needs to continue to be used, the position of the plate support needs to be adjusted so that the cutter is as close to the unworn part of the support plate as possible when cutting paper. In the prior art, since a large number of plate supports are arranged on the crossbeam and are fixed with bolts, the position of the plate support on the crossbeam cannot be changed. Usually, the position of the plate support is not adjusted, but a new plate support is directly used, which has a high production cost. In the structure of the present application, the position of the connecting plate on the piston shaft of the adjusting cylinder is changed by adjusting the first bolt and the second bolt, thereby changing the position of the crossbeam, and then changing the position of all the plate supports at one time, which makes it convenient to adjust the position of the plate support, increases the service life of the plate support, and saves costs.

[0019] Optionally, a vertical slide rail is provided on the lateral adjustment seat, the vertical adjustment seat is slidably connected to the vertical slide rail, and a vertical cylinder for driving the vertical adjustment seat to slide vertically is provided on the fixed seat, the piston shaft of the vertical cylinder faces downward, and the top of the vertical cylinder is rotatably connected to the fixed seat by setting a first connecting shaft, and the piston shaft of the vertical cylinder is rotatably connected to the top of the vertical adjustment seat by setting a second connecting shaft, and the length direction of the first connecting shaft and the second connecting shaft is parallel to the length direction of the crossbeam.

[0020] By adopting the above technical solution, the top of the vertical cylinder is rotated to connect the fixed seat, the piston shaft of the vertical cylinder is facing downward, and the bottom of the piston shaft is rotated to connect the vertical adjustment seat, which is convenient for cylinder installation. There is no need to install the cylinder on the horizontal adjustment seat, reduce the gravity of the horizontal adjustment seat, reduce the driving force of the horizontal adjustment seat sliding, and facilitate the sliding of the horizontal adjustment seat. The vertical slide rail makes the vertical adjustment seat slide stably.

[0021] Optionally, an upper slide groove and a lower slide groove are provided on the fixed seat, the top end of the transverse adjustment seat is slidably connected in the upper slide groove, and the bottom end of the transverse adjustment seat is slidably connected in the lower slide groove, and a row of horizontally arranged sliding rollers are rotatably connected in the upper slide groove and the lower slide groove, and the transverse adjustment seat contacts the side where the two rows of sliding rollers are close to each other.

[0022] By adopting the above technical solution, the sliding roller reduces the sliding resistance of the lateral adjustment seat, making it easy for the lateral adjustment seat to slide.

[0023] Optionally, a positioning roller is rotatably connected to the fixed seat, the axis of the positioning roller is in the vertical direction, the lateral adjustment seat abuts against the positioning roller toward the horizontal side wall, and the positioning roller abuts the lateral adjustment seat against the fixed seat.

[0027] The fixed frame is provided with a travel switch, and the crossbeam is provided with a contact. When the fixed frame moves in the horizontal direction, the travel switch is triggered, and the travel switch and the vertical cylinder electrical signal are connected to the production management system.

[0028] By adopting the above technical solution, when paper jam occurs, the cardboard abuts against the plate support, thereby lifting the fixed frame. After the travel switch is triggered, it transmits a signal to the production management system. The production management system sends a signal to the vertical cylinder, and the vertical cylinder lifts the crossbeam, thereby reducing equipment damage and reducing cardboard loss.

[0029] Optionally, at least two fixing brackets are provided, and the travel switches are provided at both ends of the fixing brackets.

[0030] By adopting the above technical solution, the number of travel switches is increased, and the contact points are increased. When a paper jam occurs, a travel switch will respond when either end of the fixed frame is lifted, making the paper jam detection sensitive, facilitating the production management system to carry out the corresponding subsequent procedures, and reducing equipment damage and cardboard loss.

[0053] Reference Figure 3 A buffer block 6 for abutting against the step surface 521 is fixed at the bottom of the end of the beam 1, and the buffer block 6 is a rubber block.

[0054] Reference Figure 6 , Figure 7 A mounting frame 7 for mounting a plate support 9 is installed on the cross beam 1. The mounting frame 7 includes a fixing frame 71 and a connecting structure 72 connecting the fixing frame 71 and the cross beam 1. The connecting structure 72 includes a fixing block 721 and a moving block 722. The fixing block 721 is fixed to the top surface of the cross beam 1. The moving block 722 is slidably connected to the fixing block 721. A connecting column 723 is fixed to the bottom of the moving block 722. A vertical hole is opened on the fixing block 721 for the connecting column 723 to slide. The fixing frame 71 is fixed to the bottom end of the connecting column 723.

The fixed frame 71 is provided with a plurality of plate holders 9, and the plate holders 9 are arranged along the length direction of the beam 1. A travel switch 8 is fixed on the fixed frame 71, and a contact is provided on the beam 1. When the fixed frame 71 moves in the horizontal direction, the travel switch 8 is triggered, and the travel switch 8 and the vertical cylinder 41 are sent electrical signals to connect the production management system.

[0056] The implementation principle of the beam seat mechanism for mounting the board support on the cardboard cutting device in an embodiment of the present application is as follows: during production, the fixed seat 21 is fixed on the frame of the longitudinal cutting device, the cardboard moves quickly on the longitudinal cutting device, and the cutter moves from bottom to top to cut the cardboard.

[0057] The vertical cylinder 41, the regulating cylinder 217, the step cylinder 53 and a plurality of travel switches are connected to the enterprise production management system at 8 points. When cutting five layers of cardboard, the relevant program is selected in the production management system. At this time, the step cylinder 53 drives the medium-height step surface 521 to correspond to the bottom of the buffer block 6, and the regulating cylinder 217 drives the horizontal adjustment seat 22 to slide, so that when the cutter cuts the cardboard, the cutter is located at the critical point close to the support plate 91, so that the cardboard support effect is good.

[0058] When cutting three-layer cardboard, the upper production management system controls the step cylinder 53 to drive the step block 52 to slide, so that the lowest step surface 521 is located below the buffer block 6. At the same time, the adjustment cylinder 217 drives the lateral adjustment seat 22 to slide horizontally away from the cutter direction, so that the cutter remains at the critical point close to the support plate 91 during cutting.

[0059] When cutting seven-layer cardboard, the production management system controls the step cylinder 53 to drive the step block 52 to slide, so that the highest step surface 521 is located below the buffer block 6. At the same time, the adjustment cylinder 217 drives the lateral adjustment seat 22 to slide horizontally close to the cutter direction, so that the cutter remains at the critical point close to the support plate 91 during cutting.

[0060] When the plate support 9 is worn, the support plate 91 loses 3-5mm in the depth direction of the gap between the blade combs. If the cutter is still located at the critical point close to the support plate 91 during cutting, the abutment effect of the cardboard is reduced due to the existence of the wear gap. At this time, after stopping the machine, adjust the first bolt 31 and the second bolt 32, so that the horizontal adjustment seat 22 moves horizontally 3-5mm near the cutter side and then fixes it, so that the crossbeam 1 moves horizontally near the cutter side, so that all the cutters are adjusted to be close to the cutter level at one time. When cutting, the cutter remains at the critical point close to the support plate 91, so that the plate support 9 can continue to be used, saving costs.

[0061] When a paper jam occurs, the stuck cardboard pushes the plate support upwards. At this time, the travel switch is triggered, and the vertical cylinder lifts the crossbeam. At the same time, the production management system stops the production line, reducing the waste of cardboard and preventing the equipment from being damaged.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
