DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] Please refer to Figures 2-6 As shown in the figure, a limiting structure includes a plate body 100, the lower part of the plate body 100 is fixedly connected with a round tube 190, the round tube 190 penetrates through the plate body 100, the inside of the round tube 190 is slidably connected with a guide rod 170, the guide rod 170 is connected with a baffle 140 for blocking the movement distance of the material on the material collecting side, a fixing unit 150 for fixing the guide rod 170 is arranged between the guide rod 170 and the round tube 190, so that the distance of the guide rod 170 sliding in the round tube 190 is controlled on the material feeding side, thereby adjusting the distance between the baffle 140 and the plate body 100, then the guide rod 170 is fixed by using the fixing unit 150, and when cutting to a fixed length, the material is in contact with the baffle 140 to determine the fixed length position, and the material of the fixed length can be obtained after cutting.

[0032] The number of the round tube 190 is one or two, when the round tube 190 is one, the guide rod 170 only slides relative to the round tube 190, so that the relative rotation between the guide rod 170 and the round tube 190 is prevented, and it is ensured that the baffle 140 connected to the tail of the guide rod 170 is in a parallel state;

[0033] When the number of the round tube 190 is two, a pull handle 171 is fixedly connected between the two guide rods 170 on the material feeding side, so that the user can hold the pull handle 171 to drive the two guide rods 170 to move together when using.

[0034] The outer wall of the guide rod 170 is marked with a length scale, and the user adjusts to the specified position according to the length scale during actual operation.

[0035] The circular tube 190 and the plate body 100 are fixed by welding, and the circular tube 190 can also be provided as a hollow bolt, which is combined with a nut to fix the circular tube 190 on the plate body 100.

[0036] Please refer to Figure 7 As shown, the fixing unit 150 includes a threaded cap 151 and a C-shaped ring 152, the outer wall of the circular tube 190 is provided with an outer thread 153 connected with the threaded cap 151, and the C-shaped ring 152 is located in the threaded cap 151 and abuts against the circular tube 190 at the adjacent position. When the threaded cap 151 is screwed with the circular tube 190, the C-shaped ring 152 is pressed to clamp the guide rod 170, thereby fixing the position of the guide rod 170. In this way, the user can quickly adjust and fix the position during use, improving the adjustment efficiency.

[0037] Please refer to Figure 8 As shown, the fixing unit 150 includes a hand screw nut 155, the outer wall of the guide rod 170 is provided with an outer thread 154 connected with the hand screw nut 155, and the end of the guide rod 170 at the material collecting side is sleeved with a return spring 156. By screwing the hand screw nut 155 and the outer thread 154, the relative position of the hand screw nut 155 on the guide rod 170 is changed, and combined with the elastic return characteristic of the return spring 156, the position of the baffle 140 is fixed.

[0038] Please refer to Figure 4 As shown, the guide rod 170 is fixedly connected with the baffle 140, and the baffle 140 is a baffle 141. This way can intercept and position some materials without adhesion, such as plastic rods and dried traditional Chinese medicines. After the material is cut, it will fall and separate under the action of its own gravity, and then in the next round, the material that has not been cut will be blocked, and the new material will be pushed to the baffle 140, ensuring the normal feeding.

[0039] Please refer to Figure 4 , 5As shown in Figures 6 and 9, the guide rod 170 is slidably connected to the baffle 140, and the baffle 140 is a baffle 2 142. The surface of the baffle 2 142 is provided with a slide groove 1421 that slides relative to the guide rod 170. The baffle 2 142 is connected to a tension spring 1422 that drives it close to the starting direction of cutting. Specifically, one end of the tension spring 1422 is connected to the baffle 2 142, and the other end is connected to the upper part of the baffle 142 for fixing the motor 123. The upper part of the baffle 2 142 is in contact with a blocking shaft 1423, and the blocking shaft 1423 is fixedly connected to the tool holder 130. In this way, materials that are adhered and difficult to separate from the baffle 140 can be intercepted and positioned. During cutting, the knife holder 130 moves downward with the blocking shaft 1423, and the blocking shaft 1423 is used to press the second baffle 142 downward. During cutting, the interception of the cut material is gradually removed, so that it can fall normally. As the knife holder 130 moves upward, under the traction of the tension spring 1422, the second baffle 142 is gradually moved upward to carry out a new round of interception. For example, in the field of food cutting, thin slices of potatoes and radishes will adhere to the blade. If they are intercepted by the fixed baffle 141, it is difficult to directly cut the material. With the above-mentioned means, as the cutting progresses, the material is tilted and flipped toward the position of the second baffle 142 to achieve falling.

[0040] At the end of the guide rod 170, a gasket 172, a hollow tube 173 and a gasket 172 are connected in sequence by screws 174. The hollow tube 173 slides with the slide groove 1421. If only one guide rod 170 is used, the outer contour of the hollow tube 173 is rectangular, thereby limiting the reverse rotation of the baffle 2 142 when sliding.

The outer surface of the plate body 100 is located at the feeding position and is detachably fixed with a hopper 160. When disassembling, the hopper 160 is set to a structure that slides up and down and is plugged in. After use, it can be lifted up to be detachable. When in use, it can be effectively plugged in under the action of gravity.
