In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the scope of protection of this patent.

As shown in fig. 1 to 6, in this embodiment, the table top with reversible knife strips provided by the present invention includes a table top frame 1 and a knife strip module 2, the table top frame 1 is provided with the knife strip module 2, and further includes a supporting mechanism 3, the knife strip module 2 includes a plurality of knife strips 4 arranged in parallel at intervals, and two ends of the knife strips 4 are fixed to the table top frame 1 through the supporting mechanism 3; both sides of the blade 4 are provided with sawtooth structures 5, and the sawtooth structures 5 on both sides of the blade 4 are symmetrical to bear plates and assist in cutting. Can continue to use the sawtooth structure 5 of opposite side with sword strip 4 upset after the sawtooth structure 5 of one side is impaired can't use, compare the sword strip that only one side has the sawtooth structure, the life of sword strip has increased one time, has practiced thrift the cost of sword strip greatly.

As shown in fig. 3 to 5, the blade module 2 further includes a blade pressing plate 6, the blade 4 includes side blades 7 on both sides and a middle blade 8 in the middle, the middle blade 8 is provided with a through hole 9, the blade pressing plate 6 passes through the through hole 9 of the middle blade 8, and both ends of the blade pressing plate 6 are fixedly connected to the side blades 7. The blade pressing plates 6 may be arranged in multiple groups at intervals, so as to increase the stability of the entire blade module 2, for example, five groups of blade pressing plates 6 are arranged in the embodiment shown in fig. 5, and of course, the number of the blade pressing plates 6 should be flexibly set according to specific conditions, for example, the length of the blade 4, and the application is not limited thereto.

Specifically, the knife strip pressing plate 6 comprises a strip-shaped plate 10 and mounting seats 11, and the mounting seats 11 are arranged at two ends of the strip-shaped plate 10; strip shaped plate 10 passes through-hole 9, and bar shaped hole 13 has still been seted up to bar shaped plate 7 fixed connection of 7 with side sword strips through mount pad 11 on the bar shaped plate 10, and the major axis of bar shaped hole 13 is parallel with the major axis of bar shaped plate 10. Wherein, as shown in fig. 4, the through-hole 9 that 8 middle parts of middle sword strips were seted up sets up to the cross shape hole, as shown in fig. 5, a plurality of draw-in grooves 12 have been seted up at the strip shaped plate 10 interval, and draw-in groove 12 can cooperate the joint so that strip shaped plate 10 is fixed with middle sword strip 8 with cross shape hole. Specifically, after the strip-shaped plate 10 passes through the middle of the cross-shaped hole, the strip-shaped plate 10 is pushed to the left or to the right, so that the clamping groove 12 and the cross-shaped hole can be clamped in a matched manner, and the strip-shaped plate 10 and the middle knife bar 8 are kept fixed. The side blades 7 on both sides are not provided with through holes 9, and the side blades 7 can be directly connected and fixed with the mounting seats 11 on both sides of the strip-shaped plate 10 by bolts. The mount pad 11 on the right side of the blade support plate 6 shown in fig. 5 is an integrated structure formed by bending the strip-shaped plate 10, and the mount pad 11 on the left side of the blade support plate 6 is a detachable structure connected by bolts, so that when the blade support plate 6 needs to pass through the cross-shaped hole, the mount pad 11 on one side can be detached only, and after the strip-shaped plate 10 passes through all the blades 4, the mount pad 11 is installed and fixed, and the detachment and the assembly are more convenient. After the knife strips 4 are combined to form a module, an integral sub-component is formed, so that the stress of each knife strip in the module is more uniform, and the operation during installation and overturning is more convenient when the knife strips need to be replaced.

As shown in fig. 2 to 3, the supporting mechanism 3 includes a C-shaped member with three bent sides and a blocking plate, the blocking plate is fixed at an opening of the C-shaped member, the blocking plate is provided with a fixing groove, and two ends of the blade bar 4 are inserted into the fixing groove to fix the blade bar 4 to the table top frame 1. Specifically, the supporting mechanism 3 is made by adopting a mode of three-side bending C-shaped piece and one-side welding blocking plate, the bending piece is simple to manufacture, the welding blocking plate can increase the strength of the supporting mechanism 3, the space can be saved, and a sufficient cutting breadth space is reserved for the table board. The number and the interval of the fixing grooves formed in the supporting mechanism are the same as those of the middle knife strips 8. The end part of the knife strip 4 is inserted into the fixing groove, so that the position fixing effect and the load bearing effect can be achieved.

After the knife strip modules 2 are assembled, the knife strip modules are integrally arranged on the supporting mechanisms 3, and when the knife strip modules are installed, each knife strip 4 is clamped into a corresponding fixing groove of the supporting mechanism 3, so that front and back positioning is realized. After the cutter bar 4 is installed, the cutter bar 4 is pressed by the cutter bar pressing plate 6, and the cutter bar 4 is pressed by screws through the strip holes 13 on the strip plates 10 and the screw holes on the supporting mechanism 3, so that the cutter bar 4 is fixed. And the elongated hole 13 used on the strip-shaped plate 10 can adjust the error caused by the uneven length of the knife strip 4, so that the installation is more convenient.

The supporting mechanism 3 may be fixed on the table top frame 1 by welding, or may be fixed by bolting, which is not limited in this application. The circular arc size of the circular arc of the rectangular pipe that supporting mechanism 3 used through bending the formation equals with mesa frame 1 is welded in two circular arc seams, and the welding can be more convenient, and the welding seam that forms after the welding is also more firm, also welds a welding seam between the plane of the downside arc surface of supporting mechanism 3 and mesa frame 1 to this joint strength who guarantees supporting mechanism 3 and mesa frame 1. Meanwhile, reinforcing ribs are arranged between the supporting mechanism 3 and the table top frame 1, for example, triangular reinforcing ribs can be welded, and the bearing capacity of the supporting mechanism 3 can be further enhanced.

As shown in fig. 1, a leveling plate is fixed on the upper end surface of the table top frame 1, and a guiding rule 14 is fixed on the upper end surface of the leveling plate. Because the outside of the table top frame 1 can not have other mechanisms, the guiding ruler 14 can only be installed at the position crossing the table top frame 1 and the supporting mechanism 3, the parallelism of the guiding ruler 14 needs to be ensured when the guiding ruler is installed, the upper end surface of the supporting mechanism 3 and the upper end surface of the table top frame 1 are inevitably uneven, a leveling plate can be fixed on the two surfaces in a welding mode, a knife is processed above the leveling plate, the parallelism of the leveling plate is ensured, then a mounting hole is processed on the leveling plate, and the guiding ruler 14 is fixed on the leveling plate by screws.
