DETAILED DESCRIPTION

[0022] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1-Figure 3 The utility model proposes a multi-station lifting frame for fixing a knife remover, comprising a lifting mechanism 1, a lifting frame plate 2 and a knife remover unit 3. A connecting block 4 is fixedly connected to the middle position of the top of the lifting frame plate 2. The lifting frame plate 2 is fixedly connected to the lifting mechanism 1 through the connecting block 4. A plurality of placement holes 5 are opened on the top of the lifting frame plate 2. The plurality of placement holes 5 are symmetrically arranged in pairs. A plurality of assembly holes 6 are opened on the top of the lifting frame plate 2. Four of the plurality of assembly holes 6 are arranged in a circular array on the outside of the corresponding placement holes 5. The knife remover unit 3 is fixedly installed in the corresponding placement holes 5 and the plurality of assembly holes 6.

[0024] In this embodiment, the inner side wall of the storage hole 5 is ground and polished, and a positioning groove 7 is opened on the inner side wall of the storage hole 5 .

[0025] In this embodiment, the assembly hole 6 is configured as a tapered hole, and the inner side wall of the tapered hole is configured as a smooth surface.

[0026] It should be noted that grinding and polishing can make the inner wall surface of the hole smoother and reduce surface roughness and unevenness. Polishing can eliminate the roughness of the inner wall of the hole, reduce surface defects, improve corrosion resistance, extend service life, and facilitate the insertion of the knife remover unit and prevent the surface from being scratched when the knife remover unit is inserted. The inner wall of the tapered hole gradually becomes thinner to form a cone, which improves the positioning accuracy and stability of the bolt, makes the bolt easier to install, and can provide a better tightening effect, making the knife remover unit and the lifting frame installed more stably.

[0027] In this embodiment, the lifting frame plate 2 is made of stainless steel, and the connecting block 4 is made of steel plate.

[0028] It should be noted that stainless steel has high strength and corrosion resistance, and its processing performance is also relatively good, making it easy to open holes. Steel plates also have high strength and rigidity, so they can provide better supporting performance and are more convenient in installation and maintenance.

[0029] In this embodiment, a plurality of threaded holes 8 are formed on one side of the lifting frame plate 2, and a plurality of threaded grooves are formed on one side of the connecting block 4, and the threaded holes 8 are matched with the corresponding threaded grooves.

[0030] In this embodiment, a notch groove 9 is formed on one side of the lifting frame plate 2, and a built-in groove 10 is formed on one side of the notch groove 9. The tops and bottoms of the notch groove 9 and the built-in groove 10 are both opened.

[0031] It should be noted that the provision of the notch groove and the built-in groove enables the lifting frame plate to fit closely with the frame plate of the lifting mechanism, thus playing a better role in guiding movement.

[0032] In this embodiment, a plurality of grooves are formed on one side of the connection block 4 , and first connection holes 11 are formed in the grooves.

[0033] In this embodiment, four second connection holes 12 are opened on the front side of the connection block 4, and the four connection holes are symmetrically arranged in pairs.

[0034] It should be noted that, as shown in the accompanying drawings Figure 1 As shown, the lifting mechanism is connected to the connecting block through an active slider and two auxiliary sliders. The connecting block is fastened to the matching groove body on the active slider through four first connecting holes, and is fastened to the matching groove body on the auxiliary slider through four second connecting holes. The multi-point connection improves the stability of the connection between the connecting block and the lifting mechanism, which not only enables the connecting block to obtain a larger load capacity, but also the stable installation of the connecting block can keep the lifting frame stable.

[0035] The working principle of the device in this embodiment is: the lifting frame proposed in this utility model is a part of a knife picking machine, which is used to pick up multiple knives at the same time. By placing the knife picker unit 3 through the placement hole 5, the smooth surface of the placement hole 5 can reduce the friction resistance, which is convenient for the placement of the knife picker unit 3 and prevents the surface from being scratched when the knife picker unit 3 is placed. The assembly hole 6 and the hole on the knife picker unit 3 are used for bolt connection. The setting of the tapered hole improves the positioning accuracy and stability of the bolt, makes the bolt easier to install, and can provide a better fastening effect. The lifting mechanism 1 drives the lifting frame to move up and down to perform the knife picking operation by cooperating with the connecting block 4.

[0036] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
